    Abstract ( 820 )   PDF (1805KB) ( 650 )  

    Objective·To analyze the association between talent cultivation and clinical discipline development level for affiliated hospitals of a medical school in Shanghai, determine key indexes, and propose suggestions for talent cultivation. Methods·Questionnaire survey and data search were used to collect the information on talent cultivation, medical care, teaching, and research. Based on the performance evaluation index system, the discipline development level was calculated. According to quantitative results, disciplines were classified into two categories, i.e. superior disciplines (n=33) and ordinary disciplines (n=129). The rank sum test method was used to analyze the differences in talent cultivation indexes between two types of discipline. Indexes with statistical significance were key indexes associated with the discipline development level. Results·Indexes with statistical difference (P<0.05) between two types of disciplines were the number of faculty in one discipline, the proportion of faculty with a senior professional title, the proportion of faculty with a doctoral degree, the proportion of faculty aged between 41 and 50 years, academic status of discipline leaders, talent aggregation level, the number of researchers, the number of talent projects, and the number of faculty who were trained abroad. Conclusion·We should enhance talent cultivation, pay attention to key indexes, increase the number of faculty, improve talent structure, focus on training talents aged less than 50 years, introduce and cultivate discipline leaders with high influence, elevate talent aggregation, increase the number of researchers, and obtain more talent projects and abroad training opportunities, so as to improve the discipline development level.

    doi: 10.3969/j.issn.1674-8115.2016.09.002

    Abstract ( 887 )   PDF (3067KB) ( 683 )  

    Objective·To measure the expression of ST20-AS1, a long non-coding RNA (lncRNA) in patients with T-cell lymphoma, and to explore its effects on the proliferation and invasion of T-cell lymphoma cells. Methods·Study lncRNA was screened using the lncRNA array. The association between high expression of ST20-AS1 and NOTCH signaling pathway was detected via the data from the lncRNA array. The expression level of ST20-AS1 in T-cell lymphoma patients was assessed by real-time RT-PCR and its activation effect on NOTCH signaling pathway was verified. ST20-AS1-overexpressing T-cell lymphoma cell line Jurkat was constructed and cell proliferation test and Transwell assay were performed to observe changes in cell proliferation and invasion. Results·ST20-AS1 was overexpressed and NOTCH signaling pathway was significantly activated in T-cell lymphoma patients. The overexpression of ST20-AS1 activated the NOTCH signaling pathway and promoted lymphoma cell proliferation and invasion in Jurkat. When NOTCH1 was knocked down by siRNA, cell proliferation and invasion was reduced in ST20-AS1-overexpressing cell line Jurkat. Conclusion·ST20-AS1 can activate the NOTCH signaling pathway and promote lymphoma cell proliferation and invasion.

    doi: 10.3969/j.issn.1674-8115.2016.09.003

    Abstract ( 660 )   PDF (3938KB) ( 778 )  

    Objective·To analyze the effect of S1P-receptor agonist FTY720 on the expression of different receptor subtypes of S1P, explore the major receptor subtype of S1P that binds FTY720 in cardiomyocytes of rats with myocardial infarction (MI), and further investigate the protective function on non-infarcted myocardium after MI. Methods·The SD rat model of MI was constructed and SD rats were randomly allocated to sham and MI groups, both of which were further divided into three groups treated with saline, low dosage (0.04 mg/kg) of FTY720, and high dosage (0.4 mg/kg) of FTY720. Tests were performed to compare cardiac function between different groups four weeks after treatment. RT-PCR was used to measure the expressions of S1P1, S1P2, and S1P3 receptors in myocardium before and after MI and to analyze the effect of high dosage of FTY720 on the expression of S1P receptors. Histochemical staining was used to analyze the effects of FTY720 treatment on myocardial structure, interstitial fibrosis, and cell apoptosis in non-infarcted myocardium. Western blotting was conducted to detect the effect of high dosage of FTY720 on the expressions of phosphorylated AKT and ERK in non-infarcted myocardium. Results·In normal myocardium of rats without MI, S1P1 receptor was the most predominantly expressed subtype, followed by S1P3 subtype. Four weeks after MI, the expressions of S1P receptors were significantly reduced, while high dosage FTY720 treatment could remarkably elevate the expressions of S1P1 and S1P3. Similarly, FTY720 treatment could reduce pathological changes in non-infarcted myocardial tissues after MI, including cardiac remodeling, fibrosis, and cell apoptosis. Moreover, the levels of phosphorylated AKT and ERK were significantly elevated after FTY720 treatment. Conclusion·As an important agonist of S1P receptors, FTY720 may activate the AKT and ERK pathways through acting on S1P1 and S1P3 receptors in cardiomyocytes, so as to protect the non-infarcted myocardium after MI.

    doi: 10.3969/j.issn.1674-8115.2016.09.004

    Abstract ( 688 )   PDF (828KB) ( 692 )  

    Objective·To investigate the effects of maternal vitamin D deficiency and supplementation on the immunomodulatory function of Th1/Th2 in offspring rats. Methods·Forty-eight female SD (8-week-old) rats were randomly assigned to three groups, i.e control group (C group, n=16), vitamin D deficiency group (VDD group, n=16), and vitamin D supplementation group (VDS group, n=16). C group was fed a normal diet and VDD and VDS groups were fed a vitamin D deficiency diet. After four weeks, females and males were housed in a 2∶1 ratio. After gestation, C group and VDS group were fed a normal diet and VDD group was still fed a vitamin D deficiency diet. The vitamin D level in female rats was measured using LC-MS/MS at gestational day 10 (second trimester). The vitamin D level, the ratio of Th1/Th2, and expressions of serum IFN-γ and IL-4 in offspring were measured using LC-MS/MS, flow cytometry, and ELISA 4 weeks after birth, respectively. Results·For C group, VDD group, and VDS group, the 25(OH)D levels in female rats were (23.23±2.08), (5.52±2.36), and (11.35±1.84) ng/mL, respectively, while the 25(OH)D levels in offspring were (7.15±1.30), (0.93±0.22), and (6.82±1.37) ng/mL, respectively. The 25(OH)D levels in female rats and their offspring of VDD group were significantly lower than those of C group and VDS group (P<0.05). The Th1/Th2 ratios in offspring of C group, VDD group, and VDS group were 0.90±0.35, 0.24±0.08, and 0.94±0.26, respectively. The Th1/Th2 ratio in VDD group was significantly polarized toward Th2 and polarization of Th2 in VDS group was remarkably improved compared with C group. The IFN-γ levels in C group, VDD group, and VDS group were (18.72±5.66), (8.27±3.86), and (19.31±5.68) pg/ml, and the IL-4 levels were (3.49±0.52), (4.14±0.55), and (3.52±0.52) pg/ml. The IFN-γ level significantly decreased and the IL-4 level significantly increased in VDD group compared with C group and VDS group (P<0.05). Conclusion·Vitamin D deficiency in pregnant rats caused the imbalance of Th1/Th2 (Th2 polarization) and IFN-γ/IL-4 (drifting toward IL-4) in offspring. Vitamin D supplementation significantly improved the imbalance of Th1/Th2 and IFN-γ/IL-4 in offspring.

    Abstract ( 773 )   PDF (2358KB) ( 807 )  

    Objective· To verify the safety, efficiency, and precision of the clinical application of domestic customized 3D-printing total temporomandibular joint prostheses. Methods·2 patients with temporomandibular joint osteoarthrosis were included in this study. The maxillofacial computed tomography (CT) was performed before surgery and the CT data were input into the Mimics 18.0 software. The customized total joint prostheses were designed according to the anatomy of patients’ temporomandibular joints and were made with 3D printing. The surgeries were performed after the mechanical performance test for the prostheses. The modified preauricular approach was used and the prosthesis was placed and fixed after removing affected joint nodules and condyles. The wound was closed and sutured after occlusion was examined. The clinical follow-up and radiography examinations were performed 1 week, 1 month, and 3 months after surgery. The preoperative designed position and postoperative implant position of prosthesis in CT images were compared and the deviation was analyzed. Results·The average static yield strength of the prosthesis was 3100 N. No cracks or fractures were detected during fatigue tests. Biological examinations were qualified after disinfection and sterilization. All prostheses were positioned smoothly and firmly attached to bone surfaces. Prostheses showed no displacement, loosening, and fracture in X-ray images 1 week and 3 months after surgery. The pain, diet, and mouth opening of patients were significant improved 3 months after surgery. The fitting results of preoperative and postoperative CT images indicated that the mean error between preoperative designed position and postoperative implant position of prosthesis was (0.904±0.292) mm at the fossa and (0.528±0.198) mm at the ramus. The overall mean error was (0.878±0.259) mm. Conclusion·The domestic customized 3D-printing total temporomandibular joint prosthesis is safe and efficiency for the clinical application.

    Abstract ( 606 )   PDF (1823KB) ( 880 )  

    Objective·To compare the pros and cons between digital simulation technology and conventional film template in predicting the prosthesis size before total knee arthroplasty (TKA) and provide evidence for perfect minimally invasive TKA. Methods·Sixty patients who underwent TKA from January 2015 to June 2015 were selected and assigned to the digital simulation group (DSG, n=30) and the conventional template group (CTG, n=30) based on a random number table method. In DSG, the prosthesis sizes were predicted by digital simulation of surgery, including osteotomy and placement of the prosthesis. In CTG, the comparisons between the film template and the knee X-ray radiographs were conducted to determine the prosthesis sizes. Predictive sizes and final sizes selected by surgeries were compared. The accuracies of prediction in the two groups were compared through statistical analysis of related data. Results·For the femoral prosthesis size prediction, there were 2 cases with a size difference of 1# and 1 case  with a size difference of 2# in DSG, and  7 cases with a size difference of 1# and 2 cases with a size difference of 2# in CTG. The accuracies for predicting femoral prosthesis size were 90.0% and 70.0% in DSG and CTG, respectively. For the tibial prosthesis size prediction, there were 2 cases with a size difference of 1# in DSG, and 8 cases with a size difference of 1# and 2 cases  with a size difference of 2# in CTG. The accuracies for predicting tibial prosthesis size were 93.3% and 66.7% in DSG and CTG, respectively. The differences between two groups were statistically significant. Conclusion·The prediction of prosthesis size with digital simulation technology is more accurate compared with conventional film template. This technology can provide evidence for preoperative planning, minimal invasion, and prosthesis preparation for TKA.

    Abstract ( 923 )   PDF (887KB) ( 703 )  

    Objective·To investigate the effects of ANK3 gene on the cognitive function in patients with schizophrenia. Methods·A total of 254 schizophrenia patients with stable condition and 72 healthy controls were recruited. Cognitive function was tested using RBANS and SNP rs10994336 was genotyped using TaqMan SNP genotyping assay. Results·The difference in sex between case group and control group was not statistically significant (P=0.18), while the differences in age and education were statistically significant (P<0.01). In the RBANS evaluation, patients in case group had much higher total scores and scores in immediate memory, visual span, language ability, attention, and delayed memory compared with the control group (P<0.01). The differences in the total score and scores of immediate memory, attention, and delayed memory between patients carrying three different genotypes of rs10994336 were statistically significant (P<0.01). Patients carrying T/T genotype had significantly lower RBANS scores than those carrying C/C genotype. Conclusion·ANK3 gene is significantly associated with cognitive impairment in patients with schizophrenia, especially in terms of immediate memory, attention, and delayed memory, suggesting ANK3 gene may participate in the development of cognitive impairment in patients with schizophrenia.

    Abstract ( 607 )   PDF (2563KB) ( 703 )  

    Objective·To develop a reliable and accurate 3D acetabular orientation measurement method for Chinese people. Methods·CT data of 60 (30 males and 30 females) adult patients with disease irrelevant to bones were collected. 3D models of osseous pelves were generated and the 3D coordinates of osseous pelves were manually selected and optimized via iterations. A surface-based method was used to realize semi-automatic measurement of acetabular spatial parameters and describe acetabular characteristics of Chinese people. A software was developed to verify the accuracy and reliability of this method. Results·3D model based acetabular measurement method was quite reliable (intraclass correlation coefficient [ICC]>0.999) and accurate. Both anteversion (average: 3.1°, 95%CI 2.0°-4.2°, P=0.004) and anatomic inclination (0.9°, 95%CI 0.4°-1.4°, P=0.028) of females were greater than those of males. There was no significant difference in bilateral acetabular orientation. However, bilateral differences in anteversion (maximum 9.1°) and inclination (maximum 5.7°) were observed in some individuals. Conclusion·Differences in acetabular orientation between males and females were statistically significant (P<0.05). The variation ranges of acetabular orientation were wide, especially the anteversion. Individual acetabular orientation was relatively symmetrical. 3D acetabular measurement and analysis are helpful for the diagnosis and treatment of hip disease and the design of prosthesis.

    Abstract ( 633 )   PDF (1090KB) ( 597 )  

    Objective·To investigate the hepatitis C virus (HCV) infection, knowledge related to hepatitis C virus, and treatment motivation among the heroin dependents treated in methadone maintenance treatment (MMT) clinics and to provide evidence for formulating related intervention strategies in the future. Methods·Two hundred and forty participants receiving MMT underwent serologic test to evaluate HCV infection among them. HCV related knowledge questionnaire, AUDIT, Stigma Scale, Beck Depression Inventory, and Beck Anxiety Inventory were used to assess patients. Results·The HCV infection rate among participants was 70.0% (168/240) and most of them were co-infected with hepatitis A (43.3%). HCV knowledge scores were low due to lack of self-protection consciousness and average scores were 6.5±3.5. The main factor affecting the motivation to treatment is treatment costs. Conclusion·The HCV infection rate in MMT patients is high and the patients lack related knowledge. The factors influencing the motivation for treatment are complicated.

    Abstract ( 675 )   PDF (1788KB) ( 623 )  

    Objective·To explore whether the combined use of inflammation, malnutrition, and cardiac valve calcification allows better all-cause and cardiovascular mortality risk stratification in peritoneal dialysis (PD) patients. Methods·Patients underwent regular PD in PD center of Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine from March 2011 to August 2013 were enrolled in this study. Cardiac valve calcification (CVC) in patients was detected using two-dimensional echocardiography. The patients were assigned to 4 groups based on 0, 1, 2 and all 3 risk markers, namely high high-sensitive C-reactive protein (hs-CRP), low serum albumin and CVC. All patients were followed up prospectively until death, PD discontinuation, or October 31, 2015. Cox proportional hazard model was used to analyze the prediction of all-cause and cardiovascular mortality by 0, any 1, 2 and all 3 risk markers. Results·A total of 189 PD patients with mean age of (55.8±15.2) years and median dialysis time of 20 months (9-42.5) were enrolled in this study. Among them, 99 (52.4%) were males and 32 (16.9%) had diabetes mellitus. CVC was presented in 60 (31.7%) patients. By the end of study, 46 patients died and 28 deaths were due to cardiovascular events. The patients with 3 and 2 markers had adjusted HR of 4.933 (95%CI 1.674-14.540,P=0.004) and 2.762 (95%CI 1.107-6.892,P=0.029) for all-cause mortality compared with those with 0 risk marker. The adjusted HR for cardiovascular mortality were 7.719 (95%CI 1.916-31.088, P=0.004) and 3.728 (95%CI 1.126-12.344, P=0.031) in patients with 3 and 2 markers. A combination of 3 markers increased the area under the curves of all-cause and cardiovascular mortality compared with any single marker. Conclusion·A combination of inflammation, malnutrition, and CVC can better predict the prognosis of PD patients and allow better all-cause and cardiovascular mortality risk stratification in PD patients.

    doi: 10.3969/j.issn.1674-8115.2016.09.016

    Abstract ( 496 )   PDF (1110KB) ( 661 )  

    Objective·To investigate the association between metabolic syndrome (MS) and risk of cardiovascular disease (CVD) in community-dwelling residents ≥ 40 years of age in Shanghai. Methods·The cross-sectional study was conducted in 10 185 residents aged≥40 years selected by cluster sampling from Songnan community of Baoshan District. The questionnaire was used to collect relevant medical history. Anthropometry and biochemistry measurements were also performed. Results·The prevalences of MS and CVD in study population were 30.99% and 5.97%, respectively. The prevalence of MS was significantly higher in females than in males (35.34% vs 24.40%) and increased with age. The prevalence of CVD was significantly higher in males than in females (7.45% vs 4.99%). Logistic regression analysis indicated that MS was associated with an increased risk of CVD in males (OR 1.46, 95%CI 1.11-1.92) and in females (OR 1.34, 95%CI 1.03-1.74) after adjustment for covariates including age, body mass index, smoking, drinking, exercise, and education level. Elevated blood pressure, high fasting glucose, and abdominal obesity were associated with increased risk of CVD in males with MS, while high triacylglycerol level and high fasting glucose were associated with increased risk of CVD in females. Conclusion·About one third of the residents aged ≥40 years in Songnan community had MS. MS and its components were significantly associated with increased risk of CVD.

    2016, 36 (09):  1346. 
    doi: 10.3969/j.issn.1674-8115.2016.09.017

    Abstract ( 973 )   PDF (1569KB) ( 1163 )  

    The vestibular system is a complicated operating system contributing to monitor and control balance and has functions such as motion perception, gaze, and truck stability. More recently, the vestibular system has been recognized for its contribution to emotion, memory and social cognition. Patients with vestibular dysfunction present with loss of balance, blurred vision, vertigo and so on, resulting in serious social-behavioral impairments. At the early stage of vestibular dysfunction, the vestibular system often experiences a spontaneous recovery from the static and dynamic deficit, i.e. vestibular compensation. As an extrinsic intervention, vestibular rehabilitation can actively promote the compensation in unilateral vestibular impairment. This article reviews the latest research progresses of vestibular compensation mechanism and vestibular rehabilitation ideas, i.e. the best vestibular compensation relies on cross-talk windows between retraining processes and post-lesion brain-plasticity mechanisms, rather than rehabilitation techniques.

    Abstract ( 661 )   PDF (1498KB) ( 664 )  

    Myocardial ischemia caused by coronary artery atherosclerosis is the major cause of cardiovascular disease death. Currently, administration of drugs is still an important strategy for myocardial ischemia therapy. Recent studies showed that nano drug delivery system can enhance the safety and efficacy of therapeutic agents and has great value in clinical application. Nano-DDS can deliver drugs via direct heart injection or intravenous injection. The “passive targeting” and “active targeting” properties of the nano-DDS facilitate the delivery of drugs to the site of ischemic myocardium, enhancing the concentration of drugs in the ischemic area, and improving the efficacy. This review summarizes recent studies on the application of nano-DDS to the treatment of myocardial ischemia.

    Association between cytokine gene polymorphisms and recurrent spontaneous abortion
    GAN Yue-xin, ZHANG Jun, CHEN Dan
    2016, 36 (09):  1362. 
    doi: 10.3969/j.issn.1674-8115.2016.09.020

    Abstract ( 613 )   PDF (1559KB) ( 933 )  

    Recurrent spontaneous abortion (RSA) is defined as three or more consecutive abortions before 20 weeks of gestation. Cytokines are proteins or small molecular peptides for cell signaling, immune regulation and response, which affect all stages of pregnancy and play a vital role in pregnancy outcome. Because cytokines are very important in maternal-fetal immune regulation and genetic polymorphisms have potential impact on function and expression of cytokines, the association between cytokine genetic polymorphisms and RSA has become a hot topic of international research recently. There are some problems in reported studies. For example, the results of different studies are inconsistent or even conflicting, therefore it is difficult to determine the role of cytokine polymorphisms in RSA; most studies reported several positive cases and lack verification from other populations, thus the false positive risk may exist; the sample size of case-control studies was small (<400) with low statistical power, resulting in false negative findings; tagging single-nucleotide polymorphisms (SNPs) were not fully studied, thus the causal variants may be missed; the impact of gene-gene interaction and gene-environment interaction on RSA was not investigated. Therefore, increasing the sample size, systematically studying representative genetic polymorphisms, and exploring the impact of gene-gene and gene-environment interaction on RSA become an urgent need in this field.

    Abstract ( 610 )   PDF (968KB) ( 665 )  

    Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance that is first identified during pregnancy, excluding diabetic patients diagnosed before pregnancy. GDM not only can cause adverse events in mother and infant during pregnancy, but also has long-term effects after pregnancy. GDM can increase the prevalence of type 2 diabetes, cardiovascular disease, metabolic syndrome, and depression in mothers and elevates risks of abnormal glucose metabolism, hypertension, and obesity in offspring. Effective postpartum follow up and intervention can reduce those risks. This article reviews long term effects of GDM on mothers and offspring and strategies and methods of postpartum follow up.

    OUYANG Feng-xiu, WANG Xu
    2016, 36 (09):  1378. 
    doi: 10.3969/j.issn.1674-8115.2016.09.023

    Abstract ( 833 )   PDF (1584KB) ( 1049 )  

    Accumulating evidences suggest that gut microbiota is associated with the development of obesity. Early life is a critical period for gut microbial colonization and development. Maternal vaginal flora and breast milk microbiota are important microbial sources for infant gut microbiota. In early life, the factors that influence the colonization and composition of gut microbiota include intrauterine microbial exposure, mode of delivery, type of infant feeding, antibiotic use, infant behavior and habits, geographical environment, and child genetic factors, etc. These factors may influence the development of childhood obesity via changing the composition of intestinal microbiota.

    doi: 10.3969/j.issn.1674-8115.2016.09.024

    Abstract ( 607 )   PDF (2659KB) ( 682 )  

    Thyroid-associated ophthalmopathy (TAO) is an autoimmune orbital disease which seriously damages visual function and craniofacial appearance. When TAO develops to compressive optic neuropathy or corneal exposure and is unable to be conservatively treated, orbital decompression surgery is the only way to save sight. With the advancement of surgical incision and procedures, more and more patients have undergone orbital decompression surgery to reconstruct craniofacial appearance. How to achieve effective orbital decompression in a most precise and safest way with minimal invasion has become a research hotspot of modern orbital surgery. Recently, with the proposition of orbital gradient decompression scheme, the development of digital orbital surgery technology, and the application of assistant devices such as endoscopes and computer navigation systems, precise customized pre-operative design for decompression range, precise intra-operative decompression with minimal invasion, and objective postoperative assessment have been achieved, which significantly improve the value of orbital decompression surgery in the treatment of TAO.

    Abstract ( 726 )   PDF (1008KB) ( 570 )  

    Gastric cancer is one of the most common digestive tract malignancies in Asia and prones to lymph node metastasis and hematogenous metastasis. Tumor remote metastasis is the main cause of death in patients with gastric cancer, while the molecular mechanism underlying the invasion and metastasis is still not fully clarified. Long non-coding RNA is a class of non-coding RNA molecules with a length of more than 200 nt and lack of open reading frames. Numerous studies have shown that long non-coding RNA plays an important role in multiple biological processes, including immune response, pluripotency of stem cells, and cell proliferation, apoptosis, and differentiation. Recent research indicated that long non-coding RNA is closely associated with invasion, metastasis, and prognosis of gastric cancer, as well as regulation of tumor invasion and metastasis through multiple pathways. This article reviews the latest research progresses of regulating the invasion and metastasis of gastric cancer by long non-coding RNA.
