性病艾滋病感染者HIV-1相关基因CCR5△32、CCR2b-64I、SDF1-3'A多态性分布的研究

研究HIV-1相关等位基因CCR5△32、CCR2b-64I、SDF1-3'A在性病艾滋病感染人群中的突变频率和多态性分布的特点,为我国艾滋病的预防和未来的基因治疗提供初步依据.收集198例汉族性病艾滋病感染者的血液标本,提取基因组DNA,经PCR检测,并用统计学方法分析.198例性病艾滋病人群CCR.5△32、CCR2b-64I、SDF1-3'A的突变频率分别为0.25%、16.16%、25.00%,与中国普通汉族人的结果一致.CCR5△32的突变频率较低,而CCR2b-64I、SDF1-3'A的突变频率较高,提示本地性病艾滋病汉族人群对性传播的HIV-1(R-5)毒株有较大的易感性.

重庆居民5-HT2A基因多态性与原发性高血压关系

以聚合酶链PCR法分析重庆市一般人群的5-HT2A基因C102T多态性(样本总数348人,其中高血压组:HT=137例,非高血压组:NT=211例)的临床指标间的相关性与频率分布。了解重庆地区汉族人群5-羟色胺受体2基因(5-hydroxytryptamine receptor gene,5-HT2A)C102T多态性与原发性高血压病(essential hypertension,EH)的关系。卡方检验结果显示5-HT2A的C102T基因多态性(P=0.549)与等位基因频率(P=0.263)在HT与NT之间没有显著性统计学差异;5-HT2A的C102T基因多态性与高血压logistic回归模型分析结果显示也未见显著性差异,卡方值(Wald)为0.399;比值比为0.884;95%的可信区间为0.603~1.296,P值为0.528。一般线性模型分析结果:5-HT2A基因C102T多态性与收缩压,舒张压之间没有显著性统计学差异,PSBP=0.868,PDBP=709。5-HT2A的C102T多态性可能与重庆汉族人群EH无关。     

5-羟色胺受体基因多态性位点与海洛因依赖的关联性研究

目的：5-HT（5-hydroxytryptamine,5-HT）参与了多种中枢神经活动的生理过程,其功能异常可以影响很多行为障碍,已有研究显示,5-HT水平与多种精神疾病密切相关。5-HT受体及其转运体基因在海洛因依赖发生发展中起到了重要的作用,是海洛因依赖的主要候选基因。探讨5羟色胺2A受体（Serotonin 2A receptor,HTR2A）基因启动子区-1438A/G（rs6311）、外显子区102T/C（rs6313）与5羟色胺1B受体（Serotonin 1B receptor,HTR1B）基因外显子区861G/C（rs6296）3个单核苷酸多态性和海洛因依赖的关联性分析。方法：严格按照诊断标准,选取无亲缘关系的海洛因依赖个体616例及健康个体600例提取基因组DNA,采用PCR-RFLP方法检测rs6311、rs6313和rs6296 3个SNPs位点的基因型频率,采用SPSS16.0软件分析各位点等位基因、基因型频率在病例-对照组间差异。结果：HTR2A基因rs6311和HTR1B基因rs6296位点的等位基因及基因型频率分布在2组间存在统计学差异（P〈0.05）,病例组rs6311位点的等位基因A频率显著高于对照组（X2=5.436,P=0.020,OR=1.208,CI=1.031~1.417）,rs6296位点的等位基因C频率显著高于对照组（X2=12.116,P=0.000,OR=1.329,CI=1.132~1.560）。连锁不平衡检验结果显示,HTR2A基因rs6311、rs6313位点处于不连锁状态,D＇〈0.5。结论：HTR2A基因rs6311和HTR1B基因rs6296多态性可能与海洛因成瘾有关,携带有rs6311 A等位基因与rs6296 C等位基因的人可能更容易对海洛因产生依赖。我们的研究为海洛因依赖易感人群筛选及药物靶向治疗提供了理论依据。

Distribution of the HIV-1 Resistance-Conferring Alleles (CCR5delta32, CCR2-64I, and SDF1-3′A) in Russian, Ukrainian, and Belarusian Populations

The frequencies of three alleles, CCR5delta32, CCR2-64I, and SDF1-3A, known to decrease the risk of AIDS onset and the rate of the disease progression in HIV-infected individuals were determined in three native population samples from Russia, Ukraine, and Belarus. The frequencies of the alleles were 0.15, 0.12, 0.21; 0.12, 0.07, 0.20; and 0.12, 0.08, 0.26 for Russians, Ukrainians, and Belarussians, respectively. The proportion of the individuals without any of three protective alleles among Russians, Ukrainians, and Belarussians constituted 49, 65, and 61%, respectively. The genotype frequencies for the three loci studied were in Hardy–Weinberg equilibrium. Based on the three-locus genotype frequencies, the relative hazards of AIDS onset in HIV-infected individuals in each population were calculated as ranging from 0.79 to 0.88. In the samples of Eastern Slavs analyzed the estimated frequencies of the AIDS-protective alleles tested, as well as the frequencies of the corresponding genotypes and the relative hazards of AIDS onset were within the range of these parameters for the other European populations. The data on the allele frequencies and the relative hazard values in Russians, Ukrainians, and Belarussians can be used as the predictors of AIDS onset and progression rate in HIV-1-infected individuals from the populations studied.     

Distribution of HIV-1 resistance-conferring polymorphic allelesSDF-1-3′A, CCR2-64I andCCR5-Δ32 in diverse populations of Andhra Pradesh, South India

Polymorphic allelic variants of chemokine receptors CCR2 and CCR5, as well as of stromal-derived factor-1 SDF-1, the ligand for the chemokine receptor CXCR4, are known to have protective effects against HIV-1 infection and to be involved with delay in disease progression. We have studied the DNA polymorphisms at the loci that encode these proteins in 525 healthy individuals without any history of HIV-1 infection from 11 diverse populations of Andhra Pradesh, South India. The two protective allelesSDF-1-3′A andCCR2-64I at the SDF-1 and CCR2 loci, respectively, are present in all populations studied, although their frequencies differ considerably across populations (from 17% to 35% for theSDF-1-3′A allele, and from 3% to 17% forCCR2-64I). In contrast theCCR5-δ32 allele is observed only in three populations (Yamani, Pathan and Kamma), all in low frequencies (i.e. 1% to 3%). The mean number of mutant alleles (for the three loci together) carried by each individual varies from 0.475 (in Vizag Brahmins) to 0.959 (in Bohra Muslims). The estimated relative hazard values for the populations, computed from the three-locus genotype data, are comparable to those from Africa and Southeast Asia, where AIDS is known to be widespread.

目的探讨miR-98-5p对宫颈癌细胞增殖、迁移和侵袭的影响以及其作用机制。 方法选取2016年1月至2019年1月郴州市第一人民医院收治的宫颈癌患者的癌组织和癌旁组织;予以miR-98-5p、si-PYGO2及anti-miR-98-5p单独或共培养Siha细胞,记为：miR-NC组、miR-98-5p组、si-NC组、si-PYGO2组、anti-miR-NC组、anti-miR-98-5p组、miR-98-5p+pcDNA组、miR-98-5p+pcDNA-PYGO2组。运用qRT-PCR检测宫颈癌组织和细胞中miR-98-5p和PYGO2 mRNA的表达水平;Western blot检测蛋白表达;MTT法检测细胞增殖活性;Transwell检测细胞迁移和侵袭;将WT-PYGO2、MUT-PYGO2分别与miR-NC、miR-98-5p共转染至Siha细胞中,双荧光素酶报告基因检测实验检测荧光活性。采用方差分析和t检验进行统计学分析。 结果与癌旁组织相比,宫颈癌组织中miR-98-5p表达水平降低（0.98±0.08比0.47±0.05）,PYGO2 mRNA （1.00±0.07比2.43±0.24）和蛋白表达水平（0.27±0.03比0.62±0.05）均升高（P均< 0.001）。与正常宫颈细胞Ect1/E6E7相比,宫颈癌细胞Siha、Hela、Caski中PYGO2 mRNA （0.98±0.09比2.76±0.23、2.46±0.24、2.55±0.21）和蛋白表达水平（0.21±0.03比0.62±0.06、0.51±0.05、0.57±0.06）升高;miR-98-5p的表达水平降低（1.00±0.08比0.34±0.04、0.56±0.05、0.46±0.04） （P均< 0.05）。与miR-NC组相比,miR-98-5p组宫颈癌Siha细胞活性（48 h：0.61±0.05比0.42±0.04,72 h：1.02±0.09比0.59±0.06）、迁移数量[ （112.46±10.27）个比（48.35±4.96）个]及侵袭数量[ （92.47±9.56）个比（39.46±3.52）个]均降低（P均< 0.05）。与si-NC组相比,si-PYGO2组宫颈癌Siha细胞活性（48 h：0.64±0.06比0.46±0.05,72 h：1.05±0.08比0.67±0.06）、Siha迁移数量[ （106.48±9.75）个比（42.16±4.25）个]和侵袭数量[ （87.63±8.11）个比（35.42±6.20）个]均降低（P均< 0.05）;Cyclin D1、MMP-2、MMP-9、MMP-14表达水平降低,p21、p27表达水平升高,差异有统计学意义（P均< 0.05）。与miR-NC组比较,miR-98-5p组转染WT-PYGO2的Siha细胞荧光素酶活性（0.38±0.04比0.99±0.08）降低（P < 0.05）,转染MUT-PYGO2的Siha细胞荧光素酶活性（1.03±0.08比1.01±0.09）差异无统计学意义（P > 0.05）。PYGO2过表达逆转了miR-98-5p过表达对宫颈癌Siha细胞的增殖、迁移和侵袭的抑制作用。 结论miR-98-5p可抑制宫颈癌细胞增殖、迁移和侵袭,其机制可能与其靶向调控PYGO2的表达有关,将可为宫颈癌的预防和治疗提供新靶点。     

2型糖尿病患者血清鸢尾素、摄食抑制因子-1、3-硝基酪氨酸水平与糖脂代谢和阻塞性睡眠呼吸暂停低通气综合征的关系研究

摘要 目的：探讨2型糖尿病（T2DM）患者血清鸢尾素（Irisin）、摄食抑制因子-1（Nesfatin-1）、3-硝基酪氨酸（3-NT）水平与糖脂代谢和阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的关系。方法：选择2020年4月~2021年9月期间中国人民解放军总医院京南医疗区收治的T2DM患者80例作为研究对象,根据多导睡眠图（PSG）检查结果,合并OSAHS的51例患者列为T2DM合并OSAHS组,剩余的29例纳为T2DM未合并OSAHS组。选择同期来中国人民解放军总医院京南医疗区体检的40例健康志愿者作为对照组。对比T2DM患者、对照组的Irisin、Nesfatin-1、3-NT水平,采用Pearson相关性分析显示Irisin、Nesfatin-1、3-NT与糖脂代谢指标的相关性。T2DM患者发生OSAHS的影响因素采用多因素Logistic回归分析。结果：T2DM合并OSAHS组、T2DM未合并OSAHS组Irisin低于对照组,且T2DM合并OSAHS组低于T2DM未合并OSAHS组（P<0.05）。T2DM合并OSAHS组、T2DM未合并OSAHS组Nesfatin-1、3-NT高于对照组,且T2DM合并OSAHS组高于T2DM未合并OSAHS组（P<0.05）。T2DM合并OSAHS组、T2DM未合并OSAHS组糖化血红蛋白（HbAlc）、空腹血糖（FBG）、餐后2 h血糖（2hPG）高于对照组,且T2DM合并OSAHS组高于T2DM未合并OSAHS组（P<0.05）。T2DM合并OSAHS组、T2DM未合并OSAHS组三酰甘油（TG）、低密度脂蛋白胆固醇（LDL-C）、总胆固醇（TC）较对照组高,高密度脂蛋白胆固醇（HDL-C）低于对照组（P<0.05）。Pearson相关性分析结果显示,Irisin与HbAlc、FBG、2hPG呈负相关,Nesfatin-1、3-NT与HbAlc、FBG、2hPG呈正相关（P<0.05）。T2DM合并OSAHS组、T2DM未合并OSAHS组的年龄、合并高血压、体质量指数、AHI、空腹C肽、合并冠心病对比有差异（P<0.05）。Irisin、Nesfatin-1、3-NT、HbAlc、FBG、2hPG、年龄、合并高血压是T2DM患者发生OSAHS的影响因素（P<0.05）。结论：T2DM合并OSAHS患者的Irisin、Nesfatin-1、3-NT水平表达异常,参与着机体的糖脂代谢过程及OSAHS发生,且OSAHS发生同时还受到HbAlc、FBG、2hPG、年龄、合并高血压的影响,可考虑对上述因素进行早期监测,以进行相关干预。
