对50例慢性阻塞性肺病（COPD）患者除常规治疗以外，加用扶正中药。另外随机设置对照组30例只作常规治疗。两组病例分别于治疗前后测定外周血T淋巴细胞亚群CD+3、CD+4、CD+8及4／8比值。将他们治疗后所得结果分别与标准对照组（3例）比较、两组病例之间相比较以及各自治疗前后相比较。结果显示：①COPD患者细胞免疫功能受损严重，主要是T细胞亚群低下或失调;②COPD患者治疗后T细胞亚群有所恢复，但与正常比较差异显著;③治疗组由于加用扶正中药，其T细胞亚群的恢复明显优于对照组。提示扶正中药对COPD患者细胞免疫功能的恢复有较好的疗效，值得临床应用和进一步的研究。
In 50 cases of patients with chronic obstructive pulmonary disease (COPD) in addition to conventional treatment, add Fuzheng Chinese medicine. Another random set of 30 cases of control group only for routine treatment. The ratio of CD + 3, CD + 4, CD + 8 and 4/8 of T lymphocyte subsets in peripheral blood were measured before and after treatment in two groups. Their treatment results were compared with the standard control group (3 cases), compared between the two groups and before and after treatment compared to each other. The results showed that: (1) Cellular immune function was severely impaired in patients with COPD, mainly due to the low or abnormal T cell subsets; (2) T cell subsets recovered after treatment in patients with COPD, but the difference was significant compared with the normal; (3) The T cell subsets recovered significantly better than the control group. It is indicated that Fuzheng Chinese medicine has a good effect on the recovery of cellular immune function in patients with COPD, which is worthy of clinical application and further study.
