胸腺肽α—1对胃肠道肿瘤化疗患者T淋巴细胞亚群和胃肠道反应的影响

目的观察胸腺肽α-1对胃肠肿瘤化疗患者T淋巴细胞亚群和胃肠道反应的影响。方法20例胃肠肿瘤化疗患者分为两组，观察组（n=10）化疗期间同时予以胸腺肽α-1，对照组（n=10）采用单化疗，两组病例在化疗前后分别观察T淋巴细胞亚群及胃肠道反应。结果观察组患者化疗前CD4^＋、CD8^＋和CD4^＋／CD8^＋分别为（43．7±7．5）、（27．3±2．8）和（1．5±0．1），对照组则为（39．4±6．3）、（30．9±2．5）和（1．2±0．6），两组比较差异有统计学意义（P〈0．05）；观察组化疗后CD4^＋、CD8^＋和NK细胞为（40．6±6．8）、（29．7±2．6）和（19．1±2．7），对照组则为（35．9±5．7）、（33．4±2．4）和（18．6±2．3），两组比较差异有统计学意义（P〈0．05）。观察组控制恶心、呕吐的有效率为72．5％、60．0％，对照组为40．0％，33．3％，两组比较差异有统计学意义（P〈0．05）。结论胸腺肽α-1能改善恶性肿瘤化疗患者的T细胞免疫功能和胃肠道反应。

Effects of thymosin alpha-1 on T cell subsets and gastricintestinal reaction of patients with gastricintestinal tumor

Objective To observe the effects of thymosin alpha-1 on T cell subsets and gastricintestinal reac-tion of patients with gastricintestinal tumor. Methods Twenty patients with gastricintestinal tumor were divided into two groups, observe group(n = 10) received thymosin alpha-1 during chemotherapy, and control group(n = 10) only received chemotherapy, T cell subsets and gastricintestinal reaction were observed. Results Before chemotherapy, CD+4,CD+8 and CD+4/CD+8 of observe group were(43.7±7.5),(27.3±2.8) and (1.5±0.1), and control group were (39.4±6.3), (30.9±2.5) and (1.2±0.6). There was significant difference between them (P < 0.05). After chemotherapy, CD+4, CD+8 and NK cell were (40.6±6.8)、( 29.7±2.6) and (19.1±2.7), control group (35.9±5.7), (33.4±2.4) and (18.6±2.3). There was significant difference between them (P < 0.05). Effec-tive ratio of nausea and vomit of observe group were 72.5% and 60.0%, control group 40.0% and 33.3%, There were significant differences between them(P <0.05). Conclusion Thymosin alpha-1 may ameliorate the function of T cell subsets and gastricintestinal reaction of patients with gastricintestinal tumor.
