    Objective · To design and synthesize APC/Asef peptide inhibitors and investigate the structure-activity relationship between peptides inhibitors and APC protein for exploring better inhibitors. Methods · Based on the best-class inhibitor we had found before—MAI-400, eleven peptide inhibitors were designed, which included the changes of N-terminal capping group, the first amino acid Ala, the fifth amino acid Leu and the last amino acid Glu. According to the results of fluorescence polarization activity detection system and molecular docking, the structure-activity relationship of peptide inhibitors was investigated. Results · Among the eleven peptides, MPI-11 had the highest affinity, whose half maximal inhibitory concentration (IC50) was 0.973 1 mmol/L. The capping group of peptide N-terminal with tert-butoxycarbonyl group reduced the activity slightly. The substitution of the Ala caused different results, changing into Trp, His and Thr definitely reduced the activity but the substitutionTyr or Phe did not influence the activity too much. And introducing benzene ring into the side chain of Leu had few effects on activity improving. The substitution of side chain carboxyl for amide at the C-terminal glutamate had little effect on the activity. Conclusion · Among the eleven peptides, the capping group of peptide N-terminal cannot be substituted into small groups and Ala cannot be substituted into other amino acids.

    Abstract ( 603 )   PDF (8818KB) ( 481 )  
    Objective · To explore the potential mechanism of male reproductive failure in autosomal dominant polycystic kidney disease (ADPKD) patients and analyze the outcomes of assisted reproductive technology treatment. Methods · Next-generation sequencing was performed for genetic diagnosis of 8 ADPKD patients, who came to International Peace Maternity & Child Health Hospital, Shanghai Jiao Tong University School of Medicine, for genetic counseling. The semen of ADPKD patients and normal males who came for pre-pregnancy consultation was collectedmasturbation for sperm analysis. The ultrastructure of sperm was observedtransmission electron microscopy. Outcomes of 7 patients with ADPKD who chose preimplantation genetic testing (PGT) were compared with those of 7 patients who were dystrophin (DMD) gene mutation carriers, undergoing the PGT in the same period. Results · Eight patients with ADPKD were heterozygous for polycystin 1 (PKD1) gene. Key parameters of sperm motion including progressive motility sperm percentage, curvilinear velocity, straight-line velocity, average path velocity, amplitude of lateral head displacement were much lower than those of normal semen, showing mild to severe oligozoospermia. One ADPKD patient with severe oligoathenospermia manifested bilateral seminal vesicle cysts. Transmission electron microscopy showed that the central microtubules of the sperm flagella of ADPKD patients were absent and the surrounding double microtubules were disorganized. There was no significant difference in the number of eggs, fertilization rate, cleavage rate, effective embryo rate and excellent embryo rate between the ADPKD patients and the DMD gene mutation carriers, but the ADPKD patients were prone to early abortion. Conclusion · Male reproductive failure causedADPKD may be related to many factors such as abnormal structure of sperm flagella and genital cysts. Further, PKD1 mutation may play a role in embryo implantation and early development.

    Abstract ( 683 )   PDF (7071KB) ( 389 )  
    Objective · To explore the risk factors associated with short-term progression of albuminuria in the patients with type 2 diabetes mellitus (T2DM). Methods · The retrospective cohort study design was performed to consecutively recruit 210 hospitalized T2DM patients who met the inclusion criteria, including 102 males and 108 females April 2010 to April 2015. The data of the patients twice in hospital (as baseline and follow-up information, respectively), including general data, biochemical examinations and medication were collected. Multivariate Logistic analysis was used to explore the potential risk factors for baseline albuminuria and short-term progression of albuminuria. Results · Serum uric acid levels were significantly higher in the patients with macroalbuminuria ( ≥ 300 mg/24 h) than those in the patients without albuminuria (< 30 mg/24 h) at baseline (P0.002). Among the 207 patients (excluding 3 samples with missing data) during the second hospitalization, 51 patients (24.6%) had progress in albuminuria and 156 patients (75.4%) had none. Serum uric acid levels were significantly higher in the progression group than those in the non-progression group (P0.009). Multivariate Logistic regression analysis showed that high serum uric acid level was an independent risk factor for progression of albuminuria in T2DM patients (OR1.349, 95%CI 1.014-1.793, P0.040). Conclusion · The high serum uric acid level may be an independent risk factor for short-term progression of albuminuria, and early intervention with hyperuricemia might delay the progression of diabetic kidney disease in T2DM patients.

    Abstract ( 816 )   PDF (7971KB) ( 323 )  
    Objective · To investigate the correlation of plasma lipid with gestational diabetes mellitus (GDM) and insulin resistance in women with GDM, and to analyze the effect of plasma lipid on pregnancy outcome. Methods · A total of 922 pregnant women with GDM who underwent prenatal examination in Shanghai Sixth Peoples Hospital January 2012 to April 2017 were selected for plasma lipid examination in the second trimester of pregnancy [(14.7±2.8) weeks]. Oral 75 g glucose tolerance test (OGTT) and islet function examination were performed during 24-28 weeks of pregnancy. According to the fasting triacylglycerol (TAG) level in the second trimester of pregnancy, they were divided into three groups: group T1 (TAG ≤ 1.3 mmol/L, n310), group T2 (1.31.79 mmol/L could be used as an index to predict glucose status in GDM patients (P0.001). ② Compared with group T1 and T2, group T3 showed significantly increased fasting glucose, fasting insulin, HOMA-IR, MBCI, and decreased WBSIS (all P<0.05). Multivariate linear regression analysis showed that BMI before pregnancy and TAG in the second trimester were independently correlated with HOMA-IR (β0.213, β0.224, both P0.000). BMI before pregnancy was independently correlated with MBCI (β0.811, P0.000). ③ The incidences of macrosomia and caesarean in group T3 were significantly higher than those in group T1 (both P<0.05). After adjusting for age and pre-pregnancy BMI, TAG in the second trimester did not increase the risk of macrosomia. TAG>4.19 mmol/L in the third trimester and TAG level in the second trimester to the third one increasing2.38 mmol/L or more, were high risk factors for macrosomia (both P0.001). Conclusion · Increased TAG (TAG>1.79 mmol/L) in the second trimester is an independent and correlated factor of insulin resistance, which may aggravate GDM. Increased TAG levels (TAG increasing>2.38 mmol/L) the second trimester to the third one and high TAG (TAG>4.19 mmol/L) in the third trimester are risk factors for macrosomia.

And the symptom scores of treatment group after treatment were significantly lower than those of control group (all P<0.05). The total effective rate of treatment for peripheral nerve injury in treatment group was also higher than that in control group (P<0.05). Sensory nerve conduction velocity and motor nerve conduction velocity of median nerves and common peroneal nerves after treatment were all significantly faster than those before treatment (all P<0.05). And between the two groups they were faster in treatment group after treatment (P<0.05). Conclusion · The therapeutic effect of Wenjing-Quyu-Juanbi Prescription combined with methylcobalamin on CIPN is better than that of methylcobalamin only.

    Analysis of risk factors of hyperuricemia and its outcomes of renal function in diabetes mellitus in Shanghai
    ZHAO Fang-ya1, LU Jun-qian2, ZHANG Lei2, CHEN Hai-bing1
    2019, 39 (7):  783. 
    doi: 10.3969/j.issn.1674-8115.2019.07.017

    Abstract ( 676 )   PDF (9104KB) ( 370 )  
    Objective · To analyze the risk factors of hyperuricemia (HUA) and its outcomes of renal function in patients with diabetes mellitus in Shanghai. Methods · A total of 3 454 patients with diabetes who were admitted to the Shanghai Diabetes Clinical Center July 2011 to September 2014 were selected. The prevalence of HUA, predisposing factors and renal function of diabetic patients were analyzed. Patients were divided into HUA group (n548) and normal serum uric acid (SUA) group (n2 906). General characteristics and clinical parameters of diabetic patients were compared between two groups. Pearson correlation analysis and multivariate Logistic regression were used to analyze the relationship between SUA and renal dysfunction and abnormal proteinuria in diabetic patients. Results · In Shanghai patients with diabetes, the prevalence of HUA was 15.87%, 14.52% in men, 17.80% in women. Glomerular filtration rate (GFR), fasting C-peptide, gender, age, natural logarithm of the ratio of microalbuminuria to creatinine (LnACR), glycated albumin (GA), triacylglycerol (TAG), high density lipoprotein cholesterol (HDL-C) and body mass index (BMI) were independently associated with SUA (all P<0.05). In diabetic patients with HUA, 1-SD increment in the SUA level was associated with a 0.8% increased prevalence of renal dysfunction, 0.3% increased prevalence of incident abnormal albuminuria and 0.5% decreased prevalence of hyperfiltration (all P<0.05). Conclusion · Diabetes has an important impact on HUA. Actively improving insulin resistance and controlling blood glucose may improve HUA. HUA is an independent risk factor for the occurrence and development of diabetic nephropathy. Therefore, monitoring the level of SUA in diabetic patients is of great significance in the prevention of diabetic nephropathy.

    Objective · To analyze the characteristics of radiotherapy clinical trials registered in Chinese Clinical Trials Registry (ChiCTR). Methods · The radiotherapy clinical trials registered in ChiCTR before December 1, 2018 were retrieved. Their characteristics were recorded and analyzed. Results · A total of 274 registered radiotherapy clinical trials were in ChiCTR, and the number increasedyear, in which 79.9% were preregistered, 51.5% were ongoing, and 27.4% had data monitoring committees. The top four researched diseases were lung cancer, nasopharyngeal cancer, liver cancer and esophageal cancer. 53.7% were conducted in Beijing, Shanghai, Guangdong and Sichuan. 86.4% were single-center. 69.7% were fundedindividuals or units. 40.5% focused on new radiotherapy schemes. The main types of research were intervention study (50.7%) and observational study (39.8%). Enterprise-funded projects tended to larger sample size and randomization, while self-funded projects tended to blinding (all P<0.05). Conclusion · Radiotherapy clinical trials in China are relatively standardized, but the regional distribution is unbalanced, the scale of research is small, and some registration information is incorrect or incomplete.

    Abstract ( 689 )   PDF (8102KB) ( 284 )  
    Atypical antipsychotic drugs have overcome the serious prolactin elevation and extrapyramidal symptoms of typical antipsychotic drugs, and become the first-line treatment for psychiatry. Studies have found that atypical antipsychotic drugs can modulate the immune inflammatory state of patients and affect their cognitive function, and there is increasing evidence suggesting that neuroimmune disorders may impair cognitive function in schizophrenia. This article reviews the progress of neuroimmune mechanisms of cognitive function in schizophrenia and the effect of atypical antipsychotic drugs on it.

    As a common mental disorder, panic disorder (PD) repeats unpredictably and negatively, influencing social function and life quality of patients. With the increasingly fierce social environment, the incidence of PD has been increasing yearyear which accounts for an increasing proportion of the global burden of disease. In recent years, research on the relationship between childhood trauma and PD has been increasing, which included the impact of multiple aspects of physical or emotional abuse, physical or emotional neglect, sexual abuse, and family dysfunction on PD. And as a predictor of PD, separation anxiety in childhood is closely related to PD. This paper reviews the research progress of childhood physical abuse, emotional abuse, sexual aband separation parents of PD patients.

    Abstract ( 1174 )   PDF (6501KB) ( 453 )  
    Major depressive disorder (MDD) is one of the world&prime;s major chronic and disabling mental diseases.2030, MDD is expected to be the top of all the disease burden in the world, with high prevalence, high recurrence rate, high disability rate, and high suicide rate. Suicide is the most serious consequence of MDD. Current studies showed that inflammatory levels in the central nervous system and peripheral blood of patients with MDD were higher, and increased more significantly in depressive patients with suicidal ideation or behavior. Related researches showed that increased levels of inflammatory cytokines were associated with dysregulation of kynurenine metabolic pathway, leading to imbalances in neurometabolites, such as an excess of the neurotoxic product quinolinic acid and a decrease in the protective neuropeptide picolinic acid. This paper reviews kynurenine metabolic pathway, expecting to identify the biomarkers of MDD patients with suicide.
