乳腺癌患者外周血血管内皮生长因子和T淋巴细胞亚群水平探讨

乳腺癌是最常见的女性恶性肿瘤之一,其转移是我国妇女死亡的重要原因。浸润转移与肿瘤血管生成密切相关,肿瘤由少数细胞群成长为较大的瘤体必须有新生血管的形成和逃逸免疫监视两个条件。恶性肿瘤的发生、发展及其转归与机体免疫功能状态有关,特别是细胞免疫功能受损与乳腺癌的发生密切相关。血管内皮生长因子（vascular endothelial growth factor,VEGF）可增加淋巴管内皮细胞之间的通透性,促进淋巴管生成,为肿瘤的转移创造有利条件。VEGF通过其受体VEGFR发挥生物学效应。

肝硬化患者血清TGF-β1和T淋巴细胞亚群检测的临床意义

目的：探讨了肝硬化患行血清TGF-β1和T淋巴细胞眶群的水平。方法：应用放免法测定64例肝硬化患者血清TGF-β1水平,单克隆抗体法测定T淋巴细胞亚群水平,并以35名正常健康人作比较。结果：肝硬化患者血清TGF-β1和CD8水平显著高于正常人组（P〈0．01）而CD3、CD4、CD4／CD8水平显著低于正常人组（P〈0．01）。相关分析显示,血清TGF-β1与CIMT细胞、CIM／CD8呈负相关,与CD8T细胞呈正相关。结论：肝硬化患者TGF-β1水平明显升高,而细胞免疫功能低下。TGF-β1对细胞免疫功能的抑制作用是肝硬化患者细胞免疫功能低下的原因之一。

尖锐湿疣患者外周血Thl/Th2及Tc1/Tc2亚群的检测及意义

Objective To investigate the role of T-helper (Th) and cytotoxic T (Tc) lymphocyte polarization in the pathogenesis of condyloma acuminatum (CA) and its correlation with recurrence. Methods Three-colour immunofluorescent flow cytometry was used to detect the proportion of CD3+ CD8-/IFN-γ+ (Th1),CD3+CD8-/IL-4+ (Th2), CD3+ CD8+/IFN-γ+ (Tel) and CD3+ CD8+/IL-4+ (Tc2) cells in the peripheral blood of CA patients and health controls. Results Compared to health controls, CA patients showed a decreased number of Thl (P < 0.01) and Tcl cells (P < 0.05), as well as a decreased Th1/Th2 and Tc1/Tc2 ratio (P <0.05). Furthermore, in 15 recurrent CA patients the ratio of Th1/Th2 was remarkably decreased (P < 0.01),while the ratio of Tc1/Tc2 had no significant change in comparison with health controls. Conclusion The decrease of Th1 and Tc1 subsets results in relative Th2 and Tc2 predominance, and this tendency is more significant in recurrent CA patients. The Th1 to Th2 and Te1 to Tc2 shifts in CA patients could be responsible for the fact that human papilloma virus (HPV) is hard to be eliminated.

尖锐湿疣患者外周血Thl/Th2及Tc1/Tc2亚群的检测及意义

目的 探讨辅助性T淋巴细胞(Th细胞)和细胞毒性T淋巴细胞(Tc细胞)的极化情况在尖锐湿疣(CA)发病机理中的作用及其与疾病复发的关系.方法 采用三色荧光抗体染色流式细胞术检测细胞内细胞因子的方法 ,检测30例CA患者和20名健康对照者外周血CD3+CD8-/IFN-γ+(Th1)、CD3+CD8-/IL4+(Th2)、CD3+CD8+/IFN-γ+(Tc1)和CD3+CD8+,IL-4+(Tc2)细胞比例.结果 与健康对照组比较,CA患者外周血中Thl细胞含量显著减少(P<0.01),Tc1细胞含量、Th1/Th2比值、Tc1/Tc2比值均减少(P<0.05);其中15例复发CA患者的Th1/Th2比值较正常对照显著减少(P<0.01),而Te1/Te2比值与健康对照组比较差异无统计学意义.结论 CA患者外周血Th1和Tc1细胞数减少,而Th2和Tc2细胞相对占优势,复发的CA患者这种失衡更趋严重.CA患者机体免疫状态可能存在Th1→Th2、Tc1→Tc2方向的漂移,这种漂移可能是人乳头瘤病毒(HPV)不易被有效清除或CA反复发生的一种免疫机制.
