Design, synthesis and structure-activity relationship study of APC/Asef inhibitors RUAN Cong1, ZHONG Jie2, YANG Xiu-yan2, ZHANG Jian2 2019, 39 (7):  692.  doi: 10.3969/j.issn.1674-8115.2019.07.002 Abstract ( 687 )   PDF (7716KB) ( 362 )   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.

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.

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. Related Articles | Metrics

Characteristics of radiotherapy trials registered in Chinese Clinical Trial Registry (ChiCTR) ZHANG Xin, HUANG Luo, TAO Dan, LI Cong, XIE Lin, WANG Yu-qing, LONG Bin 2019, 39 (7):  789.  doi: 10.3969/j.issn.1674-8115.2019.07.018 Abstract ( 754 )   PDF (6922KB) ( 295 )   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.

Research progress of neuroimmune mechanisms of cognitive function in schizophrenia and effect of atypical antipsychotic drugs on it WANG Dan-dan, ZHANG Chen 2019, 39 (7):  795.  doi: 10.3969/j.issn.1674-8115.2019.07.019 Abstract ( 654 )   PDF (8102KB) ( 268 )   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. Related Articles | Metrics

Research progress in the relationship between panic disorder and childhood trauma YANG Chen, WANG Zhen, SHAO Yang 2019, 39 (7):  800.  doi: 10.3969/j.issn.1674-8115.2019.07.020 Abstract ( 807 )   PDF (8272KB) ( 392 )   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. Related Articles | Metrics

Advanced research of kynurenine pathway mechanism in suicide of major depressive disorder ZHAO Dong-mei1, 2*, DING Lei1*, LIU Hong-ye1, 3, PENG Dai-hui1 2019, 39 (7):  805.  doi: 10.3969/j.issn.1674-8115.2019.07.021 Abstract ( 1110 )   PDF (6501KB) ( 415 )   Major depressive disorder (MDD) is one of the world′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. Related Articles | Metrics
