HCY水平对于2型糖尿病早期肾病的独立预测意义

目的研究血清同型半胱氨酸（HCY）水平与2型糖尿病（T2DM）早期肾病的关系。方法将收集到的112例T2DM患者作为观察组,按尿微量白蛋白含量分为三组：正常白蛋白组、早期肾病组和临床蛋白尿组,对HCY水平分别进行检测,与正常对照组进行分析比较。结果 T2DM早期肾病中HCY水平显著高于对照组,差异有统计学意义（P〈0.05）;T2DM各亚型HCY水平与对照组差异有统计学意义（P〈0.05）;且HCY的变化与尿微量白蛋白有一定相关性。结论血清HCY水平的变化与T2DM早期肾病密切相关,可作为T2DM早期肾病的预测因素,检测T2DM患者HCY水平有利于判断及诊断糖尿病早期肾病的发生。     

Hepatitis B virus infection and the risk of cancer among the Chinese population

The relationship between hepatitis B virus (HBV) and nonhepatocellular cancers remains inconclusive. This large case-control study aimed to assess the associations between HBV infection status and multiple cancers. Cases (n = 50 392) and controls (n = 11 361) were consecutively recruited from 2008 to 2016 at the First Affiliated Hospital of Nanjing Medical University. Multivariable adjusted odds ratios (aORs) and 95% confidence intervals (95% CIs) were estimated using logistic regression by adjusting age and gender. A meta-analysis based on published studies was also performed to verify the associations. Of these, 12.1% of cases and 5.5% of controls were hepatitis B surface antigen (HBsAg) seropositive. We observed significant associations between HBsAg seropositivity and esophagus cancer (aOR [95% CI] = 1.32 [1.13-1.54]), stomach cancer (1.46 [1.30-1.65]), hepatocellular carcinoma (HCC; 39.11 [35.08-43.59]), intrahepatic and extrahepatic bile duct carcinoma (ICC and ECC; 3.83 [2.58-5.67] and 1.72 [1.28-2.31]), pancreatic cancer (PaC; 1.37 [1.13-1.65]), non-Hodgkin lymphoma (NHL; 1.88 [1.61-2.20]) and leukemia (11.48 [4.05-32.56]). Additionally, compared to participants with HBsAg−/anti-HBs−/anti-HBc−, participants with HBsAg−/anti-HBs−/anti-HBc+, indicating past HBV-infected, had an increased risk of esophagus cancer (aOR [95% CI] = 1.46 [1.24-1.73]), stomach cancer (1.20 [1.04-1.39]), HCC (4.80 [3.95-5.84]) and leukemia (15.62 [2.05-119.17]). Then the overall meta-analysis also verified that HBsAg seropositivity was significantly associated with stomach cancer (OR [95% CI] = 1.23 [1.14-1.33]), ICC (4.05 [2.78-5.90]), ECC (1.73 [1.30-2.30]), PaC (1.26 [1.09-1.46]), NHL (1.95 [1.55-2.44]) and leukemia (1.54 [1.26-1.88]). In conclusion, both our case-control study and meta-analysis confirmed the significant association of HBsAg seropositivity with stomach cancer, ICC, ECC, PaC, NHL and leukemia. Of note, our findings also suggested that the risk of stomach cancer elevated for people whoever exposed to HBV.     

高同型半胱氨酸与糖尿病的相关性探讨

目的：探讨2型糖尿病(T2DM)与同型半胱氨酸(Hcy)及血脂的关系。方法回顾性分析533例 T2DM 患者(T2DM 组)和362例体检健康者(健康对照组)的实验室检查结果,比较两组血清 Hcy 水平及各项血脂指标的异常检出率。结果T2DM组患者血清 Hcy 水平及胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)异常检出率均高于健康对照组,差异均有统计学意义(P <0.05)。结论T2DM 与高 Hcy 和血脂代谢异常相关,高 Hcy 和血脂异常可能是糖尿病、心血管疾病的重要危险因素。     

产前亲子鉴定方法研究(附23例报告)

目的对23个产前案例进行亲子鉴定。方法超声监视下行羊膜穿刺术,抽取羊水30~40ml。离心收集羊水沉渣后提取其基因组DNA,同时抽取其父母双方外周血基因组DNA。应用毛细管电泳技术和五色荧光复合扩增的方法,检测所有DNA样本的16个STR基因座基因型。结果所有羊水基因组DNA均来自独立个体,无母体DNA的污染。三联体分析显示23个案例中17例为肯定亲权关系,亲子关系概率均大于0.9999,6例确定为排除亲权关系,平均排除(位点数)指标为7.67个。二联体分析显示23个案例中17例肯定父权的平均亲子关系概率为0.9997以上,6例排除亲权关系的平均排除(位点数)指标为5个,但其中1例的排除位点只有1个。结论16个STR位点的多重荧光扩增方法在对羊水中母体DNA的污染程度进行评估的同时,可以准确、可靠的应用于产前亲子鉴定。在检测单亲鉴定案例时,若排除(位点数)指标小于2时必须补充母亲样本或增加检测的STR位点指标数,直至得出明确结论。     

Seasonal and diurnal variations of atmospheric non-methane hydrocarbons in Guangzhou, China

In recent decades, high ambient ozone concentrations have become one of the major regional air quality issues in the Pearl River Delta (PRD) region. Non-methane hydrocarbons (NMHCs), as key precursors of ozone, were found to be the limiting factor in photochemical ozone formation for large areas in the PRD. For source apportioning of NMHCs as well as ozone pollution control strategies, it is necessary to obtain typical seasonal and diurnal patterns of NMHCs with a large pool of field data. To date, few studies have focused on seasonal and diurnal variations of NMHCs in urban areas of Guangzhou. This study explored the seasonal variations of most hydrocarbons concentrations with autumn maximum and spring minimum in Guangzhou. The diurnal variations of most anthropogenic NMHCs typically showed two-peak pattern with one at 8:00 in the morning and another at 20:00 in the evening, both corresponding to traffic rush hours in Guangzhou, whereas isoprene displayed a different bimodal diurnal curve. Propene, ethene, m, p-xylene and toluene were the four largest contributors to ozone formation in Guangzhou, based on the evaluation of individual NMHCs' photochemical reactivity. Therefore, an effective strategy for controlling ozone pollution may be achieved by the reduction of vehicle emissions in Guangzhou.
