胸腺肽α1对老年晚期恶性肿瘤患者细胞免疫功能的影响

Effect of thymosin alpha 1 on cellular immune function in elderly patients with malignant tumor

目的 :观察胸腺肽α1对老年恶性肿瘤患者细胞免疫功能的影响。方法 :30例老年恶性肿瘤患者 ,用胸腺肽α1治疗 2个月 ,第 1个月每日 1.6 mg,第 2个月隔日 1.6 mg,均为皮下注射 ,观察治疗前后 T细胞亚群及 NK细胞、患者生活质量、血常规及肝肾功能变化。结果 :30例患者用胸腺肽α1前 ,CD4、CD4 /CD8、NK细胞分别为 (32 .33± 6 .2 5 ) %、(0 .77± 0 .2 3) %、(16 .0 5± 6 .79) % ,治疗后为 (39.4 2± 9.2 6 ) %、(1.19± 0 .5 3) %、(2 4 .37± 8.2 3) %。治疗前后比较均有显著意义 (P<0 .0 5 ) ,患者生活质量分值治疗后比治疗前显著提高 (P<0 .0 5 )。结论 :胸腺肽α1能提高老年晚期恶性肿瘤患者的细胞免疫功能 ,是较理想的免疫增强剂。

Objective: To investigate the effect of thymosin alpha 1 on cellular immune function in the elderly patients with malignant tumor. Methods:Thirty patients with malignant tumor were injected with thymosin alpha 1 subcutaneously at the dose of 1.6 mg q.d. for the first month and q.o.d. for the following month. The number of T cell subgroups and the activity of NK cell in peripheral blood were detected and the quality of life of the patients were evaluated before treatment and at the end of treatment. Results: Treatment of thymosin alpha 1 increased the number of CD4 cells and improved the NK activity,and also improved the quality of life of the elderly patients with malignant tumor. There were no side effects found. Conclusion: Thymosin alpha 1 can enhance the cellular immune function of the elderly patients with malignant tumor.
