简介：<正>弓形虫病是由弓形虫引起的一种人兽共患性疾病,据报道全世界有5～10亿人受其感染。人患弓形虫病,其临床表现常因侵犯脏器不同而异,内,外、妇、儿、神经精神、传染病、肿瘤、眼、耳鼻喉科以及输血、器官移植、免疫缺陷等都与之密切关系,我们过去临床报道很少,主要与医院未开展弓形虫病检测以及手段落后有关。我们运用高

简介：目的探讨小儿喉乳头状瘤（JLP）患儿外周血T淋巴细胞（简称T细胞）亚群的变化及脾氨肽对JLP患儿T细胞亚群的影响和疗效。方法60例JLP病例随机分为JLP联合治疗组（30例）和JLP手术组（30例），所有JLP患者均采用喉内镜下电动吸割器切除新生物，联合治疗组术后同时口服脾氨肽辅助治疗，手术组不加任何免疫治疗。以同期体检的20例健康儿童做对照组，对JLP病例组（未治疗前）、健康对照组、JLP联合治疗组和JLP手术组进行外周血T细胞亚群的检测，并对脾氨肽辅助治疗JLP的疗效进行分析。结果治疗前JLP病例组CD3＋T细胞、CD4＋T细胞百分率及CD4＋/CD8＋T细胞比值较健康对照组降低，差异有统计学意义（P〈0.05）；治疗后JLP联合治疗组CD3＋T细胞、CD4＋T细胞百分率明显升高（P〈0.05），CD4＋/CD8＋T细胞比值恢复平衡；治疗后JLP联合治疗组较JLP手术组的疗效明显提高（P〈0.05）。结论JLP患儿存在T细胞介导的免疫功能障碍，脾氨肽可恢复JLP患儿T细胞亚群的正常比例，改善患儿的细胞免疫功能，对JLP有较好的辅助治疗作用。

简介：目的:观察角膜缘干细胞培养液对血管内皮细胞增殖的影响。方法:分别培养角膜缘干细胞及球结膜上皮细胞,并通过免疫组化检测AE-5蛋白鉴别角膜缘干细胞。搜集两组培养细胞的上清液加入培养的人脐静脉血管内皮细胞中,并设立对照组。培养24h后通过MTT法检测细胞增殖情况并进行统计学分析。结果:角膜缘干细胞AE-5染色呈阴性,而球结膜上皮细胞为阳性。加入角膜缘干细球结膜上皮细胞和对照组培养液的血管内皮细胞MTT值分别为2.097±0.079,1.981±0.034和1.990±0.044。三组间有显著性差异(F=9.169,P=0.000)。加入角膜缘干细胞培养上清液的血管内皮细胞增殖活性明显高于其他两组(P=0.005和P=0.007)。结论:角膜缘干细胞培养液能够促进血管内皮细胞的增殖,这可能是角膜缘干细胞的特征。本研究从功能学角度为角膜缘干细胞理论提供更多的依据。
