目的:观察乙型肝炎相关原发性肝癌患者(hepatitis B virus-related primary liver cancer,H B V-P L C)发生和进展过程中外周血T、N K、B细胞数量的变化,并初步探讨T淋巴细胞减少与胸腺功能的联系.方法:收集在首都医科大学附属北京地坛...目的:观察乙型肝炎相关原发性肝癌患者(hepatitis B virus-related primary liver cancer,H B V-P L C)发生和进展过程中外周血T、N K、B细胞数量的变化,并初步探讨T淋巴细胞减少与胸腺功能的联系.方法:收集在首都医科大学附属北京地坛医院住院的73例HBV-PLC患者,50例乙型肝炎肝硬化患者(liver cirrhosis,LC),37例慢性乙型肝炎(chronic hepatitis B,CHB)患者.收集3组患者一般资料和临床生化指标.采用流式方法检测3组患者外周血中CD3^+T淋巴细胞、CD4^+T、CD8^+T、CD3-CD16^+CD56^+NK、CD3-CD19^+B的分布情况,并检测了T淋巴细胞表面CD31、CD45RA分子的表达水平.结果:与CHB和LC患者相比,HBV-PLC患者外周血中性粒细胞升高,淋巴细胞减少(P<0.001);与CHB患者相比,HBV-PLC患者外周血NK细胞计数减少(P=0.011),T淋巴细胞、CD4^+T、C D8^+T、B细胞计数减少,纯真CD4^+和CD8^+T细胞表面CD31表达降低(P<0.001).在肝癌Child、Okuda、BCLC分期中晚期比早期淋巴细胞计数、T、CD4^+T、CD8^+T计数均降低(P<0.05).结论:随着肝癌的发生和进展,HBV-PLC患者外周血抗肿瘤免疫细胞减少,这种减少与胸腺迁出功能降低有关.展开更多

文摘目的:系统评价西格列汀改善2型糖尿病患者胰岛B细胞功能的效果,为临床提供循证参考。方法:计算机检索Pub Med、Cochrane图书馆、EMBase、中国期刊全文数据库、万方数据库、中文科技期刊数据库和中国生物医学文献数据库,收集西格列汀单药或联合常规方案(试验组)对比安慰剂单用或联合常规方案(对照组)治疗2型糖尿病的随机对照试验(RCT),由两位研究者根据纳入与排除标准独立筛选文献、提取资料,按照Cochrane系统评价员手册5.1.0评价纳入研究的方法学质量后,采用Rev Man 5.3统计软件进行Meta分析。结果:纳入了5项RCT,合计1 253例患者。Meta分析结果显示,试验组患者胰岛B细胞功能指数(Homa-B)变化值[西格列汀单药治疗组:MD=9.21,95%CI(4.16,14.25),P<0.001;联合用药组:MD=7.24,95%CI(0.80,13.68),P=0.03]和胰岛素抵抗指数(Homa-IR)变化值[西格列汀单药治疗组:MD=-0.40,95%CI(-0.44,-0.36),P<0.001;联合用药组:MD=-0.35,95%CI(-0.63,-0.07),P=0.02]均显著优于对照组,差异均有统计学意义。结论:西格列汀在改善胰岛B细胞功能及胰岛素抵抗方面有一定效果。
