The Gene Polymorphism of VMAT2 Is Associated with Risk of Schizophrenia in Male Han Chinese

ObjectiveTo investigate the association between gene polymorphism of vesicular monoamine transporter type 2(VMAT2) and schizophrenia in Han Chinese population. Methods430 patients with schizophrenia and 470 age-sex matched controls were recruited from four mental health centers. All patients were diagnosed by two psychiatrists based on the Structured Clinical Interview for DSM Disorders (SCID). The ligase detection reactions (LDR) method was used to assess the polymorphism of the two SNPs (rs363371 and rs363324) of VMAT2. ResultsNo associations of two SNPs with schizophrenia was found. When we stratified males and females for the analysis, we found that that in the recessive model of rs363371, there was an obvious significant association between rs363371 and schizophrenia in males (OR=0.564, 95% CI=0.357–0.892, p=0.014) but not females. For the association between rs363324 and schizophrenia, no association was found in either males or females. No association was found when stratifying early-onset schizophrenia and late-onset schizophrenia. ConclusionOur findings indicate that both rs363371 and rs363324 were not associated with schizophrenia, while it seemed that the AA genotype of rs363371 plays a protective effect in male Chinese in developing schizophrenia.     

维吾尔族、汉族癫痫患儿左乙拉西坦血药浓度与疗效及安全性的相关性研究

目的 研究新疆维吾尔族、汉族癫痫患儿左乙拉西坦（levetiracetam,LEV）血药浓度与临床疗效及安全性之间的相关性及差异性,同时预测可获得最佳疗效的LEV稳态谷浓度（steady valley concentration,Css）。方法 采用UPLC测定300例口服LEV的癫痫患儿的Css,分析族别对LEV Css的影响;观察其疗效和不良反应,并运用Logistic回归和受试者操作特征（receiver operating characteristic curve,ROC）曲线分析维吾尔族、汉族癫痫患儿血药浓度与疗效的关系。结果 LEV的浓度剂量比（concentration-dose ratio,CDR）结果显示其在维吾尔族、汉族患儿之间的差异均无统计学意义。2组患儿在0~4岁年龄组的CDR值差异有统计学意义（P<0.05）。2组患儿的LEV给药剂量和血药浓度均呈正相关,其中维吾尔族患儿组的相关性（r=0.628,P<0.01）优于汉族患儿组（r=0.545,P<0.01）。2组患儿LEV治疗有效率分别为78.43%,81.63%。2组患儿LEV治疗有效组与无效组的LEV Css差异均具有统计学意义（P<0.05）。Logistic回归分析发现在一定浓度范围（4.07~30.88 mg·L^-1）内,2组患儿LEV Css与疗效呈正相关。2组患儿中Css对于疗效的预判准确性均强于给药剂量。当维吾尔族患儿Css ≥ 13.15 mg·L^-1和汉族患儿Css ≥ 9.28 mg·L^-1时,其临床疗效均可得到更好的保证。结论 新疆维吾尔族、汉族癫痫患儿LEV血药浓度和临床疗效及安全性之间既存在相关性又存在不同程度的差异性,通过监测LEV Css可以提高临床疗效、避免不良反应,并为新疆癫痫患儿制订个体化给药方案提供参考。

The CMYA5 gene confers risk for both schizophrenia and major depressive disorder in the Han Chinese population

Objectives. A recent genome-wide association study (GWAS) of the European population implicated the CMYA5 gene in schizophrenia. Previous functional studies showed that the CMYA5 protein can interact with DTNBP1 and PKA, providing further support for a role of CMYA5 in the pathogenesis of schizophrenia. However, this association requires additional validation in independent populations. Methods. To validate the association between CMYA5 and schizophrenia and major depressive disorder, we genotyped 16 SNPs within the CMYA5 gene and performed case–control studies in 1330 schizophrenia patients, 1045 patients with major depressive disorder, and 1235 normal controls. All patients were of Han Chinese origin. Results. rs6883197 and rs259127 were significantly associated with schizophrenia, and rs12514461, rs259127, and rs7343 were associated with major depressive disorder. Additionally, one risk haplotype of rs16877109–rs3828611 (G–G) was associated with both schizophrenia (P = 0.0000784, after correction) and major depressive disorder (P = 0.00230, after correction). Conclusions. Our findings support the idea that specific alleles and haplotype in the CMYA5 confer genetic risk for both schizophrenia and major depressive disorder in the Han Chinese population.     

湖南汉族人群脂联素基因多态性分布及其与动脉粥样硬化性脑梗死和相关危险因素的关系

目的探讨脂联素基因45T/G和276G/T多态位点在湖南地区汉族人群中的分布及其与动脉粥样硬化性脑梗死和相关危险因素的关系。方法收集163例正常对照者和161例动脉粥样硬化性脑梗死患者的血标本,聚合酶链反应限制片长多态性分析法检测脂联素基因45T/G和276G/T多态性在动脉粥样硬化性脑梗死组和正常对照组的基因频率,同时检测研究对象的血脂和血压水平。结果中国湖南地区汉族人群脂联素基因45T/G和276G/T位点等位基因频率分别是0.783/0.217和0.697/0.303。脂联素基因45T/G多态位点等位基因和基因型分布频率两组相比差异无统计学意义(P>0.05);动脉粥样硬化性脑梗死组脂联素基因276G/T多态位点TT基因型频率和T等位基因频率明显高于对照组(P<0.05),且TT基因型亚组甘油三酯水平较GG基因型亚组显著升高,差异有统计学意义(P<0.05)。结论脂联素基因45T/G多态性可能与中国湖南汉族人群动脉粥样硬化性脑梗死的发生无关;276G/T多态性可能参与中国湖南汉族人群动脉粥样硬化性脑梗死的发生,且可能影响血脂水平,276TT型者可能具有较高水平的甘油三酯。

Seasonal variation of mogrosides in Lo Han Kuo (<Emphasis Type="Italic">Siraitia grosvenori</Emphasis>) fruits

Mogrosides at different growth stages of Lo Han Kuo (Siraitia grosvenori) fruits were analyzed qualitatively and quantitatively using TLC and HPLC. The results show that we can clearly discriminate the seasonal variation of the main mogrosides in Lo Han Kuo fruits: mogroside V is the main constituent of ripe fruits, while mogrosides III and II E are the leading components in unripe fruits. A comprehensive validation (sensitivity, linearity, reproducibility and recovery) of an HPLC method that can simultaneously determine the content of mogrosides V, III and II E was conducted. This method is proposed as a simple, rapid and accurate method for quantitative determination of the mogroside V, mogroside III and mogroside II E content in various samples of Lo Han Kuo (S. grosvenori) fruits.
