    Objective

    ·To study the changes of phosphorylation level of whole-cell proteins during the process of concanavalin A (ConA)-induced hepatocyte injury.

    Methods

    ·Mouse hepatocytes of AML12 cells and ConA (10 μg/mL) were co-cultured to induce a hepatocyte injury model. After 12 h, the total proteins were extracted and digested into peptides. The peptides were enriched by metal oxide affinity chromatography and detected by using high performance liquid chromatography-mass spectrometer. Identification and relative quantitative analysis of phosphorylation sites and peptides were performed using the Label free method. Proteins with a difference of more than two times of phosphorylation level of each site were screened. And the biological function enrichment analysis and protein interaction regulation network analysis were performed.

    Results

    ·In the ConA-induced AML12 cell injury model, a total of 11 200 phosphorylated modified peptides and 2 685 localizable and quantifiable peptides were identified. Among them, there were 82 differentially regulated phosphorylated modified peptides, corresponding to 77 proteins. These phosphorylated proteins were mainly related to protein binding and enzyme activities. And the main pathways were related to apoptosis and RAS kinase pathways.

    Conclusion

    ·AML12 cells undergo phosphorylation level change in ConA-induced liver cell injury and these differentially phosphorylated proteins may be related to liver cell apoptosis.

    Objective

    ·To take the systemic lupus erythematosus (SLE)-associated single nucleotide polymorphism (SNP) rs1978421 reported in the genome-wide association study (GWAS) as an example, and establish the research strategy for the functional study of disease-associated genetic variants located in the non-coding region through clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (CRISPR/Cas9) system.

    Methods

    ·Single guide RNA (sgRNA) was designed for SNP rs1978421. T7 endonuclease Ⅰ (T7E Ⅰ) experiment was used to verify the cleavage efficiency of sgRNA in HEK293T cells. The homologous recombinant template and expression plasmid of Cas9-green fluorescent protein (GFP)/sgRNA were transfected into U-937 cells by electroporation transfection method. GFP positive U-937 single cells were sorted by flow cytometry, and the cells were cultured for the following 14 days. Then the genotype identification was carried out. After the homologous recombinant cell clones were screened, quantitative real-time PCR (qPCR) was used to quantify the upstream and downstream genes of rs1978421 within 2 Mb and miR-146a, and the effects of different alleles of rs1978421 on the expression of miR-146a and its surrounding genes were analyzed.

    Results

    ·T7E Ⅰ assay showed that about 24% of the total rs1978421 sites in HEK293T were cleaved. In homologous recombination experiment of the U-937 cells, a total of 141 cell lines were obtained and only six were successful, while the ratio of homologous recombination was 4.3%. qPCR showed that there was no significant difference in the expression of miR-146a and the detected genes between wild type TT and homologous recombinant CC in the U-937 cells (all P>0.05).

    Conclusion

    ·SNP rs1978421 has no regulatory effect on the surrounding genes within 2 Mb and miR-146a. However, this study proves the feasibility of CRISPR-mediated homologous recombination technology for the functional study of SNP sites in the non-coding regions.

    Han-yue FU, Xu HUANG, Hong-li LU, Wen-xie XU
    JOURNAL OF SHANGHAI JIAOTONG UNIVERSITY (MEDICAL SCIENCE)    2021, 41 (1): 23-28.   DOI: 10.3969/j.issn.1674-8115.2021.01.004
    Abstract230)   HTML13)    PDF(pc) (2356KB)(134)       Save
    Objective

    ·To observe the effect of protease activated receptor 2 (PAR2) on colonic motility in chronic stress-treated mice, and investigate its mechanism.

    Methods

    ·The mice were treated with chronic heterogenous stress for 14 days to establish the chronic stress model. Western blotting was used to determine the expressions of PAR2, platelet-derived growth factor receptor α (PDGFRα) and small conductance calcium-activated potassium channel 3 (SK3 channel), while the effects of PAR2 agonist and SK3 channel antagonist on colonic motility were observed by isometric tension experiment. T-test was used for statistical analysis. Statistical significance was accepted at the value of P<0.05.

    Results

    ·Twenty-four hours after being treated by stress stimulation, the mice demonstrated a decrease of colonic transmission because the number of fecal pellets decreased significantly; simultaneously, the expression of PAR2 increased in the colon smooth muscle tissue of chronic stress-treated mice. The inhibition of colonic smooth muscle contractions by PAR2 agonist was more significant in the chronic stress-treated mice than that in the control ones. The expression of PDGFRα in colonic smooth muscle tissue of chronic stress-treated mice increased, but the expression of SK3 had no obvious change, compared with the control mice. The inhibition of colonic smooth muscle contractions by SK3 channel antagonist was not significantly different between chronic stress-treated mice and the control mice.

    Conclusion

    ·In the colons of chronic stress-treated mice, PAR2 activity and expression both increase, which may be responsible for the decrease of colonic motility.

    JOURNAL OF SHANGHAI JIAOTONG UNIVERSITY (MEDICAL SCIENCE)    2021, 41 (1): 29-34.   DOI: 10.3969/j.issn.1674-8115.2021.01.005
    Abstract232)   HTML18)    PDF(pc) (1598KB)(88)       Save
    Objective

    ·To clarify the correlation between nitric oxide synthase 1 adaptor protein (NOS1AP) gene and Han Chinese schizophrenia patients, and predict the changes in the secondary structure of RNA and protein caused by variation of NOS1AP gene positive polymorphism.

    Methods

    ·From October 2012 to December 2015, 333 patients with early onset schizophrenia (EOS) and 491 patients with non-early onset schizophrenia (non-EOS) were included from Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine, and 901 healthy controls (HC) were selected from the staff of Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine and the people receiving physical examination in the Physical Examination Center of Qingpu Branch of Zhongshan Hospital Affiliated to Fudan University through recruitment. The rs12742393, rs4145621 and rs1415263 polymorphisms of NOS1AP gene were detected by TaqMan probe. The Hardy-Weinberg (H-W) equilibrium of the three polymorphism loci and the allele and genotype frequencies were analyzed by the SHEsis online software. The optimal genetic model analysis was carried out by the SNPstats online website. RNAfold and DNAstar softwares were used to predict the secondary structures of RNA and protein encoded by the significantly different polymorphism locus.

    Results

    JOURNAL OF SHANGHAI JIAOTONG UNIVERSITY (MEDICAL SCIENCE)    2021, 41 (1): 35-41.   DOI: 10.3969/j.issn.1674-8115.2021.01.006
    Abstract191)   HTML4)    PDF(pc) (3168KB)(89)       Save
    Objective

    ·To study the therapeutic effect of the combination of fasudil and C-C chemokine receptor type 5-transducted mesenchymal stem cells (CCR5-MSCs) on experimental autoimmune encephalomyelitis (EAE).

    Methods

    ·The mice immunized with myelin oligodendrocyte glycoprotein peptide fragment 35-55 (MOG35-55) were randomly divided into EAE model group (intraperitoneal injection of normal saline), fasudil intervention group (intraperitoneal injection of fasudil), CCR5-MSCs intervention group (nasal administration of CCR5-MSCs), and fasudil combined with CCR5-MSCs intervention group (intranasal administration of CCR5-MSCs, intraperitoneal injection of fasudil), with 8 mice in each group. The clinical score of EAE mice were checked every day after MOG35-55 immunization. All mice were sacrificed on the 28th day after the first immunization. The myelin integrity was observed by luxol fast blue staining. The production of neural stem cells and oligodendrocyte precursor cells in spinal cord tissue was analyzed by immunofluorescence staining. The expressions of neurotrophic factors in spinal cord tissue were detected by Western blotting.

    Results

    ·Compared with the other three groups, the clinical score of EAE in the fasudil combined with CCR5-MSCs intervention group was lower (P=0.000, P=0.007, P=0.005), and the demyelination was reduced (P=0.000, P=0.009, P=0.008). The production of neural stem cells and oligodendrocyte precursor cells in spinal cord tissue was increased (all P=0.000), and the expression of brain-derived neurotrophic factor, glial cell-derived neurotrophic factor, nerve growth factor, and neurotrophin-3 increased (all P=0.000).

    Conclusion

    ·Fasudil combined with CCR5-MSCs is more effective than fasudil or CCR5-MSCs in the treatment of EAE, which may be related to the induction of remyelination and the production of the neurotrophic factor.

    Yan TONG, Jun-yan FANG, Hai DENG, A-hui SONG, Pu LI, Ying-li LIU
    JOURNAL OF SHANGHAI JIAOTONG UNIVERSITY (MEDICAL SCIENCE)    2021, 41 (1): 42-48.   DOI: 10.3969/j.issn.1674-8115.2021.01.007
    Abstract234)   HTML1)    PDF(pc) (2527KB)(120)       Save
    Objective

    ·To extract and identify the exosomes in peritoneal dialysis effluent (PDE), compare the different expression levels of PDE exosomal miR-200a in patients with different peritoneal transport characteristics, predict the potential target genes of miR-200a and analyze the related biological processes.

    Methods

    ·Twenty stable peritoneal dialysis (PD) patients were divided into two groups, i.e., H group (high/high average) and L group (low/low average) according to the values of peritoneal equilibration test (PET). Overnight PDE 500 mL from each patient was collected, concentrated, and ultracentrifuged to obtain exosomes. Transmission electron microscope (TEM), nanoparticle tracking analysis (NTA) and Western blotting were used to identify and characterize the exosomes. Exosomal miRNAs were extracted and the expression levels of PDE exosomal miR-200a in the two groups were determined by real-time quantitative PCR. The relations between exosomal miR-200a levels and PET values or ultrafiltration volume (UF) were analyzed. The target genes of miR-200a were predicted by Targetscan, miRmap and miRWalk, and DAVID was used to perform gene ontology (GO) enrichment analysis.

    Results

    ·The exosomes extracted from concentrated PDE by ultracentrifugation exhibited a round and bilayer membrane-enveloped vesicle structure under TEM with the diameters ranging from 50-150 nm. The exosomes also expressed the particular molecular marker CD9 and CD63. The relative expression level of PDE exosomal miR-200a in L group was higher than that of H group. The expression levels were negatively correlated with PET values (r=-0.871, P=0.000) and positively correlated with 4 h UF (r=0.448, P=0.048). But there was no relationship between miR-200a and 24 h UF (r=0.355, P=0.125). Bioinformatic results showed that there were 679 target genes of miR-200a that could be predicted by all the three databases. GO analysis suggested that these genes not only participated in positive regulation of mesenchymal cells proliferation, but also focused on ion binding, especially metal cation binding.

    Conclusion

    ·Exosomes indeed exist in PDE. The relative expression level of exosomal miR-200a is higher in the PDE from the patients with low peritoneal dialysis transport characteristics. The relative quantity of miR-200a is negatively correlated with the values of PET and positively correlated with 4 h UF. There are abundant potential target genes of miR-200a, indicating that it may affect the peritoneal transport characteristics by different biological processes.

    JOURNAL OF SHANGHAI JIAOTONG UNIVERSITY (MEDICAL SCIENCE)    2021, 41 (1): 49-54.   DOI: 10.3969/j.issn.1674-8115.2021.01.008
    Abstract271)   HTML6)    PDF(pc) (1645KB)(160)       Save
    Objective

    ·To investigate the effect of gestational diabetes mellitus (GDM) on the cortisol level in neonatal umbilical cord blood, and explore the effects of high perinatal cortisol exposure on neonatal health status at preschool-period.

    Methods

    ·A total of 170 mothers and their full-term neonates were selected, including 66 cases in GDM group and 104 cases in normal glucose tolerance (NGT) group. The umbilical cord blood from the newborns of the two groups was collected to measure the concentrations of cortisol and adrenocorticotropic hormone (ACTH). SPSS software was used to analyze the effect of GDM on cortisol and ACTH levels in the neonatal umbilical cord blood. Multiple linear regression model was used to analyze the influencing factors of cortisol level in the umbilical cord blood. Pearson χ2 method was used to analyze the effects of perinatal high cortisol on the health status of offspring at preschool-period, and binary Logistic regression model was used to analyze the influencing factors of preschool-period obesity.

    Results

    ·Compared with the NGT group, the cortisol level of neonatal umbilical cord blood in the GDM group was higher and ACTH level was lower (both P<0.05). Multiple linear regression analysis showed that maternal gestational times, and blood glucose at 1 h and 2 h after 75 g oral glucose tolerance test (OGTT) were the independent influencing factors of neonatal umbilical cord blood cortisol level (all P<0.05). The follow-up results showed that the offspring with higher perinatal cortisol level had higher pre-school obesity rate (P=0.009). Binary Logistic regression analysis confirmed that neonatal umbilical cord blood cortisol level ≥ 192.00 ng/mL was an independent risk factor of preschool-period obesity (OR=4.714, P=0.016).

    Conclusion

    ·Maternal GDM can cause the increase of neonatal umbilical cord blood cortisol level. High perinatal cortisol exposure can increase the risk of preschool-period obesity in the offspring. GDM may cause long-term diseases in the offspring through perinatal high cortisol exposure.

    Objective

    ·To investigate the correlations of soluble interleukin-2 receptor (sIL-2R) and tumor necrosis factor-α (TNF-α) with lupus nephritis (LN) and their predictive values in disease activity of LN.

    Methods

    ·This was a cross-sectional study. From January 2018 to December 2018, 40 patients who underwent kidney biopsy and was diagnosed as having LN and 68 healthy controls in Renji Hospital, Shanghai Jiao Tong University School of Medicine were included. Clinical characteristics and laboratory parameters were collected and serum sIL-2R and TNF-α were measured. Serum sIL-2R and TNF-α were compared between the LN group and the control group. The correlations of sIL-2R and TNF-α with laboratory parameters of LN were evaluated by Spearman analysis. Further, the LN patients were divided into the active group and the non-active group. The predictive values of sIL-2R and TNF-α were evaluated by Logistic analysis and receiver operating characteristic (ROC) curve.

    Results

    ·Serum sIL-2R and TNF-α levels were significantly higher in the LN group than those in the control group (all P<0.05). Positive correlations were observed between sIL-2R and systemic lupus erythematosus disease activity index-2000 (SLEDAI-2K), 24 hours urine total protein (24h-UTP), anti-double stranded DNA antibody (anti-dsDNA), serum creatinine and high sensitive C-reactive protein (h-CRP) (all P<0.05), while a negative correlation was found between sIL-2R and C3 (P=0.002). Meanwhile, TNF-α positively correlated with SLEDAI-2K, 24h-UTP, serum creatinine and h-CRP, whereas no significant correlation was found between TNF-α and anti-dsDNA or C3. 24h-UTP, anti-dsDNA, serum creatinine, sIL-2R and TNF-α were significantly higher (all P<0.05) and C3 was lower in the active group than those in the non-active group of LN (P=0.000). Anti-dsDNA (OR=1.025) and sIL-2R (OR=1.011) were predictive factors of disease activity of LN (all P<0.05) and the area under ROC curve of their combination of prediction was 0.957 (P=0.000).

    Conclusion

    ·Serum sIL-2R and TNF-α levels increase in LN patients and are correlated with the disease activity of LN. Combining anti-dsDNA and sIL-2R can predict the disease activity of LN effectively.

    Abstract171)   HTML0)    PDF(pc) (1007KB)(96)       Save
    Objective

    ·To investigate the correlation between early quantitative electroencephalogram (QEEG) features and brain CT perfusion imaging parameters in the patients with acute ischemic stroke (AIS), and analyze the correlation between QEEG features and National Institutes of Health Stroke Scale (NIHSS) score.

    Methods

    ·Ninety-two patients with AIS admitted to the First People's Hospital of Qinzhou from March 2014 to June 2016 were enrolled. All the patients were given emergency CT perfusion imaging to determine the ischemic lesion areas. And then they were monitored by electroencephalogram for at least 2 h. The assessment by using NIHSS was performed after admission. Cerebral blood flow (CBF), mean transit time (MTT) and time to peak (TTP) were obtained from CT perfusion imaging. α wave index, θ wave index, δ wave index, slow wave index, α/δ power ratio (ADR), (δ+θ)/(α+β) power ratio and brain symmetry index (BSI) were obtained from QEEG analysis. With Pearson linear correlation analysis, the correlation between CT perfusion imaging parameters and QEEG features in the ischemic lesions, the correlation between CT perfusion imaging parameters and NIHSS score, and the correlation between QEEG features and NIHSS score were analyzed.

    Results

    ·The AIS patients had decreased CBF, prolonged MTT and TTP, increased δ wave index, slow wave index and BSI, and decreased ADR and DTABR in the ischemic lesion areas than those in the contralateral regions. The differences were statistically significant (all P<0.05). MTT was positively correlated with δ wave index, slow wave index and BSI (all P<0.05), and negatively correlated with ADR and DTABR (all P<0.05); TTP was positively correlated with δ wave index, slow wave index and BSI (all P<0.05), and negatively correlated with ADR and DTABR (all P<0.05); the NIHSS score was positively correlated with MTT, TTP, δ wave index, slow wave index and BSI (all P<0.05), and negatively correlated with CBF, ADR and DTABR (all P<0.05).

    Conclusion

    ·There exists correlation between QEEG features and CT perfusion imaging parameters in the patients with AIS. Early recording of the patients' QEEG features can help assess the changes of ischemic lesions and neurological deficits and realize dynamic monitoring.

Also, mean arterial pressure (MAP) and heart rate (HR) were recorded at different time points, including before anesthesia induction (T1) and 1 (T2), 3 (T3), 5 (T4) and 10 (T5) minutes after tracheal intubation. On the second day after surgery, the intubation complications like coughing, hoarseness, sore throat and tissue damage were observed.

    Results

    ·There were no significant differences in general features among the three groups. Group C has the shortest tracheal intubation time (P=0.007, P=0.001). The fluctuation of MAP (P=0.006, P=0.031) and HR (P=0.013,P=0.042) at T2 in goup C were significantly shorter than the other two groups. Moreover, the incidence of sore throat decreased remarkably in group C compared with group B (P=0.010).

    Conclusion

    ·UE visual laryngoscope combined with Seeing Optical Stylet is recommended in tracheal intubation for obese patients under general anesthesia, which has an advantage of rapid intubation, stable haemodynamics during intubation and fewer complications.

    JOURNAL OF SHANGHAI JIAOTONG UNIVERSITY (MEDICAL SCIENCE)    2021, 41 (1): 82-88.   DOI: 10.3969/j.issn.1674-8115.2021.01.015
    Abstract184)   HTML2)    PDF(pc) (1132KB)(77)       Save
    Objective

    ·To analyze the perception of fertility preservation of the male patients with malignant tumors consulted in Grade-A tertiary hospitals in China through questionnaires.

    Methods

    ·From January 1st, 2018 to December 31, 2018, responses from the male cancer patients (≤50 years old) who had been treated in Renji Hospital, Shanghai Jiao Tong University School of Medicine were collected through a questionnaire survey.

    Result

    ·There were 212 male patients diagnosed with malignant tumor with a median age of (34.4±0.5) years in the current study. Among them, 61 (28.8%) were childless, 27 (12.7%) had a brief comprehension of fertility preservation, 28 (13.2%) intended to do fertility preservation, and 87 (41.0%) were aware that chemotherapy and radiotherapy might affect their fertility. Moreover, 27 patients who approximately understand fertility preservation got this knowledge from various ways. Nineteen of them (70.4%) were informed from doctors, 5 (18.5%) from media and 6 (22.2%) from internet. Male patients who have kids tended to refuse fertility preservation (P=0.000). Patients younger than 25 years old in the group were more likely to have children (P=0.046). Those with bachelor degree or above (P=0.006), and those with the desire to preserve fertility (P=0.010) were more likely to understand fertility preservation. Therefore, receiving chemo-radiotherapy (P=0.013) or not as well as having children (P=0.044) or not were two main reasons influencing patients' willingness to choose fertility preservation.

    Conclusion

    ·At present, the majority of male patients with cancer lack of the knowledge of fertility preservation, which may be due to the low literacy level of patients and inadequate publicity of medical workers. Consequently, medical staffs need to enhance the propaganda of fertility preservation, in case that patients with fertility intention lose the chance of reproduction .

    The management of diabetic nephropathy is grim, and its pathogenic mechanism is complicated. Epigenetics is gaining attention due to the discovery of "metabolic memory". Pathological changes of diabetic nephropathy include podocyte lesion, mesangial matrix change, epithelial-mesenchymal transition, etc. And its pathogenic mechanism involves processes such as oxidative stress, end-products of glycosylation, autophagy and apoptosis. As important parts of it, histone acetylation, methylation, ubiquitination and other modifications are widely involved in the above processes. Drugs targeting histone modification under experimental conditions have obtained positive results. This article reviews progresses of the histone modification and targeted treatment in the pathogenesis of diabetic nephropathy.

    With the development of science and technology, more and more attention has been paid to perioperative microcirculation management. In anesthesia, with the influence of anesthetics, non-anesthetic drugs, surgery, fluid therapy and other factors, microcirculation disorder exists in humans. The benefits of fluid therapy for microcirculation have been more popular than other factors. Anesthesiologists or experts in intensive medical all have ever put forward the concept of microcirculation-oriented fluid therapy or fluid resuscitation, which lacks a large number of clinical studies. At present, the sidestream dark field technology can realize the bedside, non-invasive and real-time monitoring of body microcirculation, and it safely comes into practice in clinical background. It helps monitor the state of microcirculation timely, and thus it's believed that the microcirculation and prognosis of patients can be improved by adjusting the category of fluid and controlling the infusion speed and fluid volume. Microcirculation-oriented fluid therapy will undoubtedly become an important direction of anesthesia management in the future. This article reviews the relative research progress in perioperative microcirculation.

    Non-alcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease, along with the prevalence of obesity and metabolic syndrome. Non-alcoholic fatty liver will progress to non-alcoholic steatohepatitis (NASH), NASH-related liver fibrosis and liver cirrhosis, and even hepatocellular carcinoma. Accurate assessment and early intervention are conducive to clinical burden reduction and disease control. Although being the "golden standard" for diagnosing NAFLD, the clinical application of liver biopsy is limited due to well-known limitations and significant complications. Serological testing, as a noninvasive method, has been well-recognized among researchers and clinicians. The understanding of the pros and cons and the application ranges of various methods and indexes is helpful for clinical applications, including providing more diagnosis approaches, improving diagnosis power, relieving pain of patients, and saving medical resources. This article reviews the advances in serological noninvasive diagnostic methods for NAFLD.

    JOURNAL OF SHANGHAI JIAOTONG UNIVERSITY (MEDICAL SCIENCE)    2021, 41 (1): 118-122.   DOI: 10.3969/j.issn.1674-8115.2021.01.022
    Abstract195)   HTML1)    PDF(pc) (1577KB)(109)       Save
    Objective

    ·To investigate the expression of breast cancer susceptibility gene 1 (BRCA1) protein in brain glioma tissue and its influence on the sensitivity of temozolomide (TMZ).

    Methods

    ·A total of 104 patients with brain glioma (study group) who underwent surgical resection in the Department of Neurosurgery, Shanxi Provincial Cancer Hospital from January 2010 to December 2017 were collected. And 30 patients with head injury (control group) who underwent internal decompression surgery were collected. The BRCA1 protein expressions in brain tissues of the two groups were detected by immunohistochemistry. The relationship between BRCA1 protein expression and the clinicopathological characteristics of brain glioma patients was analyzed by χ2 test. The survival rate of the glioma patients with BRCA1 protein positive or negative expression was calculated by Kaplan-Meier method, and the difference between the positive patients and the negative patients was tested by Log-Rank method. The U251 cells were randomly divided into three groups, and transfected with shRNA-BRCA1 silencing vector (sh-BRCA1 group), shNC-BRCA1 empty expression vector (sh-NC group) and blank control phosphate buffer saline (Blank group), respectively. The transfection efficiency of the three groups was detected by quantitative PCR (qPCR). CCK-8 method was used to detect proliferative activity of U251 cells in the three groups and the sensitivity of TMZ.

    Results

    ·Immunohistochemistry showed that 23 of the 30 control tissues were BRCA1 positive, with a positive expression rate of 76.67%, while 33 of the 104 glioma tissues were positive, with a positive expression rate of 31.73%; the difference in the positive expression rates between the two groups was statistically significant (P=0.009). In the study group, the expression of BRCA1 protein in the tumor tissues with pathological grade Ⅰ~Ⅱ was significantly higher than that in the tumor tissues with pathological grade Ⅲ~Ⅳ (P=0.022), and there was no significant correlation between BRCA1 protein expression and the patient's age, gender and pathological type. There was no significant difference in the survival rates between BRCA1 positive and negative patients. The results of in vitro studies showed that the BRCA1 mRNA expression level in the sh-BRCA1 group was significantly lower than those in the sh-NC group (P=0.037) and the Blank group (P=0.035). After transfection and 48 and 72 h of cell culture, the cell proliferation activity of the sh-BRCA1 group was higher than those of the Blank group (P=0.043, P=0.037) and the sh-NC group (P=0.046, P=0.037); when the TMZ concentration was 100 and 200 μmol/L, the cell proliferation activity of the sh-BRAC1 group was higher than those of the sh-NC group (P=0.041, P=0.040) and the Blank group (P=0.038, P=0.042).

    Conclusion

    ·BRCA1 protein is lower expressed in brain glioma, and the positive expression of BRCA1 is related to the tumor pathological grade, but not related to the patient's age, gender, pathological type and survival rate. Inhibition of BRCA1 expression can reduce the sensitivity of brain glioma cells to TMZ.

    A 16-year-old female patient was admitted to hospital because of "gradual decline in visual acuity for more than 4 months". Ocular fundus examination revealed yellowish old hemorrhage in the macular area of both eyes, and fresh hemorrhage in the superficial retinal layer of the right eye. The patient had a history of bone marrow recurrence with previous acute myeloid leukemia (AML). After bone marrow transplantation in the Department of Hematology and Oncology, the patient's vision was improved and fundus hemorrhage was absorbed. Before the diagnosis of relapse of AML, the patient's vision had declined, but she did not go to the ophthalmology clinic in time. For leukemia patients, doctors are recommended to carry out adequate education for possible extramedullary symptoms and suggest regular ophthalmology consultations. If concomitant symptoms occur, it is suggested that multidisciplinary doctors should cooperate in diagnosis and treatment in order to obtain better therapeutic effect, restore visual function and improve the quality of life of patients.

    Klinefelter syndrome (KS) is a chromosomal abnormality that is described to be one of the most common reasons for male infertility. The clinical symptoms of this disease are not typical in childhood, and it can also be accompanied by metabolic syndrome in adolescence and adulthood in addition to sexual developmental abnormalities. A case of KS with elevated blood glucose as the chief complaint was reported in this article. He was diagnosed as having diabetes mellitus in the beginning and then diagnosed as having KS complicated with type 2 diabetes mellitus after medical history inquiry and further examinations. The case suggests that clinicians need to improve their understanding of KS in order to provide diagnosis and treatment in time.

    Abstract123)   HTML177)    PDF(pc) (1943KB)(66)       Save
    Objective

    ·To investigate the effects of various wheel-running exercise intensity on activation of protein kinase B/mammalian target of rapamycin (PKB/mTOR, AKT/mTOR) pathway in cortical neurons and nerve conduction in mice.

    Methods

    ·Twenty four adult C57BL/6J mice were randomly divided into control group, low exercise intensity (LEI) group, moderate exercise intensity (MEI) group and high exercise intensity (HEI) group, with 6 mice in each group. The four groups of mice received pre-training for 3 days, and then received formal training (1 week) with different intensity. Motor-evoked potential (MEP) was used to detect the nerve conduction in the right upper limb of mice. The expression of AKT, ribosomal S6 protein (S6), insulin-like growth factor 1 (IGF1) and brain-derived growth factor (BDNF) in the motor cortex of mice were detected by Western blotting.

    Results

    ·MEP test showed that compared with the control group, the N1 latency period of MEP in the LEI group, MEI Group and HEI group was shorter (all P<0.05); compared with the HEI group, the N1 latency period in the LEI group was shorter (P=0.032). Meanwhile, compared with the control group, the P1 latency period of MEP in the LEI group was also shorter (P=0.015). Western blotting results showed that compared with the control group, the expression levels of p-AKT/AKT and p-S6/S6 in the motor cortex of mice in the LEI group, MEI Group and HEI group were significantly increased (all P<0.05); the expression levels of IGF1 and BDNF in the motor cortex of mice in the LEI group were higher than those in the control group (both P<0.05).

    Conclusion

    ·Low intensity exercise training can activate AKT/mTOR pathway of cortical neurons and improve the nerve conduction speed, which may be related to the increased nerve growth factors.

    Abstract97)   HTML180)    PDF(pc) (3508KB)(67)       Save
    Objective

    ·To identify the differentially expressed genes (DEGs) in podocyte injury and validate the expression of METTL10, one of these critical genes.

    Methods

    ·The microarray expression profile of a podocyte injury model, dataset GSE108629, was downloaded from the GEO database, containing 4 normal podocyte samples and 4 injured podocyte samples, and the DEGs were diagnosed using the limma software package and affy software package (|log FC| ≥ 2 and adjusted P value<0.05). Patients with significant proteinuria who underwent renal biopsy and were diagnosed as focal segmental glomerulosclerosis or minimal change disease were retrospectively enrolled. Control group was patients who underwent renal biopsy and were proven as slight pathological changes or benign arteriolar neophrosclerosis. The general and clinical data were collected, and the expression of METTL10 in renal tissue was detected by immunofluorescence staining. Adriamycin (ADR)-induced nephropathy mouse model was established by a single intravenous injection of ADR into BAL/BC mouse. Mice were randomly divided into two groups: control group (treated with the same volume of PBS) and ADR group (treated with ADR 10 mg/kg body weight). On Day 0 and Day 14, urine was collected for 24 h using a metabolic cage and urinary albumin creatinine ratio (UACR) of mice were detected; on Day 15, mice were sacrificed and kidney tissue was collected. The expression of METTL10 and podocyte marker proteins like synaptopodin, nephrin, podocin, and Wilms' tumor 1 (WT1) in kidneys from ADR-treated mouse model was analyzed by Western blotting.

    Results

    ·A total of 5 353 genes were significantly differentially expressed in injured podocytes compared with intact podocytes, among which 3 402 DEGs were up-regulated and 1 951 DEGs were down-regulated. METTL10 was found to be one of those that overe significantly down-regulated. Immunofluorescence staining indicated that METTL10 was expressed in normal human glomeruli and METTL10 was colocalized with podocalyxin, one of podocyte specific markers. Additionally, METTL10 was low expressed in the renal biopsy specimens from patients with significant proteinuria compared with that in the control group. On Day 14 after administration of ADR, mice developed significant proteinuria, shown by UACR detection (P=0.005); Western blotting revealed that METTL10 was significantly down-regulated (P=0.001), along with the significantly decreased expression of synaptopodin (P=0.001), nephrin (P=0.005), podocin (P=0.000) and WT1 (P=0.006) in ADR-treated mice compared with that in normal mice. The differences of the expression of METTL10 and the above podocyte markers between these two groups were statistically significant.

    Conclusion

    Objective

    ·To prepare and crystallize a novel oral bacterial serine protease inhibitor Tannerpin with high purity by means of biochemistry and structural biology.

    Methods

    ·A novel serine protease inhibitor was screened from periodontal disease-related bacteria by amino acid sequence analysis, and named as Tannerpin. The fusion expression vector pSUMO3-Tannerpin was constructed and transferred into E. coli BL21 (DE3) system for induction expression. Tannerpin was isolated and purified by a combination of nickel-affinity chromatography, SUMO-specific protease 2 (SENP2) digestion and gel filtration chromatography, and was verified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Then, the crystallization conditions of the purified protein were screened and optimized, and its acting substrates were screened.

    Results

    ·SDS-PAGE showed that SUMO3-Tannerpin fusion protein was successfully expressed in E. coli. After removing the fusion label of the protein by purification scheme, Tannerpin with relative molecular weight of about 43 000 was obtained. After crystallization screening and optimization, Tannerpin crystals with a resolution of 1.7 ? were finally obtained under the conditions of 20 ℃, pH=6.0, precipitant of 28% polyethylene glycol 3350 and 8% Tacsimate. However, the acting substrate of Tannerpin was not obtained.

    Conclusion

    ·A novel serine protease inhibitor Tannerpin secreted by oral bacteria and its crystal are successfully prepared, which may lay a foundation for subsequent structural analysis and functional study.

    Abstract86)   HTML11)    PDF(pc) (1195KB)(33)       Save
    Objective

    ·To study the association of CREB1 gene with depression and bipolar disorder type Ⅱ.

    Methods

    ·Three hundred and sixty-two patients with depression, 381 patients with bipolar disorder type Ⅱ and 416 healthy subjects were included. There were no significant differences in gender, age and year of education between depression group, bipolar disorder type Ⅱ group and control group. Patients with severity of depression were evaluated by Hamilton Depression Rating Scale. Hypomania Check List-32 was used to screen the history of hypomanic episode of patients with depression and patients with bipolar disorder type Ⅱ. A total of 2 mL of venous blood was collected from each subject, and whole genome of peripheral blood leukocyte DNA was extracted using a centrifugal column genomic DNA kit. Single nucleotide polymorphism (SNP) genotyping of SNaPshot was used to identify the rs10932201 and rs3770704 loci of CREB1 gene, and the effects of SNP on CREB1 expression in brain were analyzed using BRAINEAC database.

    Results

    ·The genotypes of rs10932201 and rs3770704 of CREB1 gene in the depression group, bipolar disorder type Ⅱ group and control group were well matched with Hardy-Weinberg equilibrium (P>0.05). Linkage disequilibrium analysis showed that there was a strong linkage disequilibrium between rs10932201 and rs3770704 (r2>0.4). At the rs10932201 locus of CREB1 gene, there was a significant difference in allelic frequency between the bipolar disorder type Ⅱ group and the control group (χ2=4.27, P=0.042); there was no difference in allelic frequency between the depression group and the control group. There were no significant differences in either allelic or genotypic frequency of rs3770704 of CREB1 gene in the depression group and bipolar disorder type Ⅱ group compared with the control group. In the haplotype constructed between rs10932201 and rs3770704 of CREB1 gene, the frequency of haplotype A-T in the bipolar disorder type Ⅱ group was 57.5%, which was statistically significant (χ2=4.07,P=0.044). Expression quantitative trait loci analysis showed that rs10932201 was associated with CREB1 gene expression in temporal cortex (P=0.048).

    Conclusion

    ·The rs10932201 of CREB1 gene is associated with bipolar disorder type Ⅱ, and may be a risk factor for bipolar disorder type Ⅱ, not depression.

    JOURNAL OF SHANGHAI JIAOTONG UNIVERSITY (MEDICAL SCIENCE)    2021, 41 (10): 1313-1317.   DOI: 10.3969/j.issn.1674-8115.2021.10.007
    Abstract88)   HTML10)    PDF(pc) (1195KB)(24)       Save
    Objective

    ·To explore the application of nonlinear mixed effects model based on the allometric equation on up-and-down data to determine the half effective dose (ED50) in pediatric patients.

    Methods

    ·Twenty-two pediatric patients aged 2 to 12 years with obstructive sleep apnea (OSA) who were undergoing drug-induced sleep endoscopy (DISE) were enrolled. All patients received intravenous bolus S+-ketamine 0.5 mg/kg. At the same time, a predetermined bolus dose of dexmedetomidine was infused continuously over 10 min for anesthesia induction. The bolus dose of dexmedetomidine was calculated according to the Dixon up-and-down method with initial dose 1.0 μg/kg and step size 1.2 times. DISE was conducted 10 min after dexmedetomidine infusion, and the response of the patients to the procedure was recorded. Dixon-Massey formula and nonlinear mixed effects model fitting are used to calculate ED50.

    Results

    ·There were 9 and 13 children with successful and failed sedation. The value of dexmedetomidine ED50, 1.9 μg/kg, calculated by Dixon-Massey formula was similar to the fitting value, 2.0 μg/kg, of nonlinear mixed effects model. The introduction of allometric equation significantly improved the model (P<0.05). After normalizing adults' body weight to 70 kg, the ED50 and ED95 were 5.76×(body weight/70) μg/kg and 11.5×(body weight/70) μg/kg, and the slope (γ) of the dose-response relationship of dexmedetomidine is 4.25.

    Conclusion

    ·The experimental data from the up-and-down method can be fitted with a nonlinear mixed effects model based on the allometric equation. Compared with the Massey formula, the advantage is that the ED50, ED95 and γ can be determined at the same time, and this method helps to determine the possible effect of covariates.

    Abstract81)   HTML5)    PDF(pc) (1408KB)(25)       Save
    Objective

    ·To establish a decision-making model for primary headache based on Nomogram.

    Methods

    ·Two hundred and ten patients with migraine or tension-type headache who visited the Department of Neurology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine between October 2019 to December 2020 were studied retrospectively. Among them, 152 patients who visited the hospital from October 2019 to August 2020 were served as the modeling group. Fifty eight patients who visited the hospital from September 2020 to December 2020 were served as the validation group. Univariate and multivariate Logistic regression were used to analyze the independent predictive factors to distinguish migraine and tension-type headache. According to the regression coefficient of independent variables, R software was used to construct a nomogram model of migraine or tension-type headache. The internal verification of the model was carried out through Bootstrap, and the external verification was carried out according to the data of the validation group. Receiver operator characteristic curve (ROC curve), area under the curve (AUC) and calibration curve were used respectively to estimate the discrimination and calibration of the prediction model.

    Results

    ·There were 80 patients with migraines and 72 patients with tension-type headaches in the modeling group. There were 35 patients with migraines and 23 patients with tension-type headaches in the validation group. There was no statistical difference in characteristics between the modeling group and the validation group. According to the results of univariate Logistic analysis, 9 characteristic variables were extracted and included in the multivariate analysis. Multivariate Logistic regression analysis showed the independent predictive factors that were used to distinguish migraine and tension-type headache, including course, whether the headache was located in the occipital, severity intensity of the headache, whether the headache was accompanied by nausea/vomiting, whether the headache was accompanied by photophobia/phonophobia and the change of headache after activities. The decision Nomogram model was constructed based on this result. The internal and external verification of the model found that AUC of the modeling group and the validation group were 0.896 [95% confidence interval (CI) 0.842?0.950] and 0.884 (95%CI 0.793?0.976) respectively, suggesting that the prediction model has a good discrimination capacity.The calibration curve of the modeling group and the validation group was very close to the standard curve, and had a good calibration degree, which showed that the model was consistent in the two groups.

    Conclusion

    ·This study has constructed a decision-making model for distinguishing migraine and tension-type headache based on Nomogram. The model has a good discrimination and calibration in the modeling group and the validation group, which is beneficial to improve clinicians' early identification and diagnosis capabilities for migraine and tension-type headache.

    Objective

    ·To improve the understanding of upfront surgical strategy in the treatment of Wilms tumor (WT) and standardize the upfront resection procedure and subsequent chemotherapy and/or radiotherapy approach, providing necessary data support for clinical study in childhood WT in China.

    Method

    ·From January 1, 2010 to December 30, 2017, the clinical records of patients with unilateral favorable histology WT (FHWT) who were initially diagnosed at Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine were retrospectively collected. All cases were diagnosed, staged and treated according to the Chinese Children Cancer Group (CCCG)-WT-2009 or CCCG-WT-2015 Protocol. Surgical outcome, event-free survival (EFS) and overall survival (OS) were analyzed using SPSS software, version 25.0. Follow-up was updated to March 31, 2020.

    Result

    ·A total of 79 consecutive cases with unilateral FHWT were enrolled, including 41 males and 38 females, with a median age of 27.1 months. Systemic staging showed that there were 7 cases with stage Ⅰ, 39 cases with stage Ⅱ, 23 cases with stage Ⅲ and 10 cases with stage Ⅳ. Sixty-nine patients (87.3%) underwent nephrectomy and 10 patients (12.7%) underwent biopsy of renal tumor tissue (2 with core needle biopsy and 8 with open biopsy) in the primary operation. Eleven cases experienced disease progression/recurrence and 1 abandoned treatment and returned to original treatment plan after 8 weeks. Local radiation therapy was applied to 27 of 32 patients with indication. Only 3 of 10 patients with lung metastasis at diagnosis received whole lung radiation therapy. A median follow-up of 69 cases without incident was 69.8 months. The 5-year EFS and OS of all cases were 84.8% and 92.4% respectively. The 5-year EFS of children with stage Ⅰ, Ⅱ, Ⅲ and Ⅳ were 100.0%, 84.6%, 95.7% and 50.0% (P=0.010), respectively. And the 5-year OS of children with stage Ⅰ, Ⅱ, Ⅲ and Ⅳ were 100.0%, 94.9%, 95.7 and 70.0% (P=0.070), respectively. The 5-year EFS of children with stage Ⅲ/Ⅳ receiving initial nephrectomy was higher than that of those undergoing biopsy (91.3% vs 60.0%, P= 0.032). The 5-year EFS of children with initial biopsy, who underwent nephrectomy at week 6 was significantly higher than that of those who did not (100% vs 0, P=0.005).

    Conclusion

    ·The upfront tumor surgical strategy of unilateral WT is safe, feasible and effective in the treatment of FHWT. Initial nephrectomy and clearance of all local diseases with lymph nodal sampling is the key to staging and successful treatment.

    Objective

    ·To evaluate the prognostic value of preoperative delayed diuretic 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) imaging in patients with bladder cancer.

    Methods

    ·The clinical data and preoperative delayed diuretic 18F-FDG PET/CT images of 104 bladder cancer patients who received radical cystectomy (RC) from 2016 to 2018 at Renji Hospital, Shanghai Jiao Tong University School of Medicine were retrospectively analyzed. The diagnostic ability and optimal boundary values of maximum standardized uptake value (SUVmax), tumor metabolic volume (MTV) and total lesion glycolysis (TLG) were obtained by receiver operating characteristic curve (ROC) analysis. Patients were divided into high SUVmax group (n=53) and low SUVmax group (n=51), high MTV group (n=52)and low MTV group (n=52), high TLG group (n=67)and low TLG group (n=37). The correlation between PET/CT metabolic parameters and clinical data was analyzed by chi-square test. Survival curves were drawn by Kaplan-Meier method and tested by Log-rank method. The prognostic value of metabolic parameters was evaluated by Cox regression model.

    Results

    ·MTV (P=0.000) and TLG (P=0.000) had diagnostic abilities for postoperative recurrence of bladder cancer. Preoperative treatment (P=0.033) and T stage of tumor (P=0.035) were correlated with MTV, while neutrophil-lymphocyte ratio (NLR) (P=0.026), hemoglobin (P=0.004), albumin(P=0.021), preoperative treatment (P=0.015) and T stage (P=0.015) were related to TLG. Multivariate Cox regression analysis showed that lymph node metastasis (HR=2.433, P=0.016) and TLG (HR=4.499, P=0.000) were independent prognostic factors of progression-free survival (PFS), while preoperative treatment (HR=0.220, P=0.014) and TLG (HR=7.107,P=0.013) were independent predictors of overall survival (OS).

    Conclusion

    ·Delayed diuretic 18F-FDG PET/CT before RC can predict the postoperative survival.

    Objective

    ·To introduce the Brief human immunodeficiency virus (HIV) Knowledge Questionnaire (HIV-KQ-18), evaluate the reliability and validity of the scale in the HIV-negative sexually transmitted diseases (STD) patients, and predict the population's sexual behavior based on its knowledge score.

    Methods

    ·A total of 599 eligible patients who attended the outpatient clinic of Shanghai Skin Disease Hospital from January 2018 to December 2018 were evaluated by the Chinese version of HIV-KQ-18, and they were randomly allocated into two groups for exploratory factor analysis (n=300) and confirmatory factor analysis (n=299). Consistent condom use when having sex was judged as safe sexual behavior and used as a dependent variable, and HIV-KQ-18 scores were used as independent variables for receiver operating characteristic curve analysis to predict safe sexual behavior.

    Results

    ·The exploratory factor analysis showed that three factors including the transmission of HIV (7 items), preventive measures (4 items) and consequences of being infected with HIV (3 items) could be extracted. Four items were removed from HIV-KQ-18 to form the Chinese version of HIV-KQ-14. Confirmatory factor analysis showed that the model revised by three factors fitted well (χ2/df=2.046, root mean square error of approximation=0.059, incremental fit index=0.926, Tucker-Lewis index=0.908, comparative fit index=0.925). The Cronbach′s α of the scale was 0.861, and the Spearman-Brown coefficient was 0.815; the area under the curve of safe sexual behavior was 0.708 (P=0.000).

    Conclusion

    ·The Chinese version of the HIV-KQ-14 has good reliability and validity in HIV-negative STD patients, and has a good predictive ability for safe sexual behavior.

    Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique. It can modulate brain current activities and treat psychiatric disorder through affecting neural excitability and synaptic plasticity.
