摘　　要：目的观察除翳解毒方对单纯疱疹病毒性角膜炎(HSK)大鼠模型血清中CD4^+、CD8^+T细胞及其比值的影响,从细胞免疫水平探讨除翳解毒方对HSK的作用机制。方法将SD大鼠80只,随机分为正常组、模型组、中西药治疗组、西药对照组,每组20只;中西药治疗组给予除翳解毒方^+更昔洛韦眼凝胶治疗、西药对照组给予更昔洛韦眼凝胶治疗。各组大鼠行裂隙灯显微镜检查、眼前节照相,泪液细胞学培养,Biw;第6 w末,模型组、中西药治疗组及西药对照组大鼠行紫外线照射,制造复发感染模型;第10 w末,处死全部大鼠,行角膜组织氯化金染色检测角膜神经纤维,流式细胞仪检测CD4^+、CD8^+T细胞及其比值。结果本实验成功建立了原发、复发感染HSK大鼠模型;氯化金染色模型组大鼠角膜神经纤维束稀疏、变细、变短;中西药组大鼠治疗后角膜神经纤维较丰富,呈网络结构;西药组神经纤维束较稀疏,大致呈网络结构;模型组与正常组比较,CD4^+T细胞减少,CD8^+T细胞增加,CD4^+/CD8^+降低,差异有统计学意义(P<0.01);中西药组、西药组与模型组比较,CD4^+T细胞增加,CD8^+T细胞减少,CD^+4/CD^+8升高,差异有统计学意义(P<0.01);中西药组与西药组比较,CD4^+T细胞增加, CD8^+T细胞减少, CD4^+/CD8^+升高,差异有统计学意义(P<0.05)。结论除翳解毒方能够增加CD4^+、减少CD8^+T淋巴细胞数量,可以调节复发性HSK大鼠模型的免疫功能,减少HSK复发。OBJECTIVE To investigate the effect of Chuyi Jiedu decoction on the serum levels of CD4＋, CDS＋T cells and their ratio in the herpes simplex keratitis （HSK） rats and to reveal its mechanism at cell immunological level. METHODS Eighty Sprague-Dawley rats were randomly divided into four groups： normal group, model group, Chuyi Jiedu decoction combined ganciclovir ophthalmic gel group, and ganciclovir ophthalmic gel group. There were 20 rats in each group. Rats in Chuyi Jiedu decoction and ganciclovir ophthalmic gel group were treated by Chuyi Jiedu decoction and ganciclovir ophthalmic gel. The ganciclovir ophthalmic gel group was given ganciclovir ophthalmic gel. Slit lamp microscopy, anterior segment photography, and tear fluid cytology culture were used in each group to test rats twice a week. At the end of the sixth week, rats in the model group, the Chuyi Jiedu Decoction and ganciclovir ophthalmic gel group, and ganciclovir ophthalmic gel group were irradiated with ultraviolet rays to induce recurrence infection. At the end of the 10t＂ chloride staining, and CD4＋, CD8 ＋T cells week, corneal nerve fibers were examined by Gold and their ratios were measured by flow cytometry. RESULTS The primary and recurrent HSK rat model was successfully established in this experiment. The corneal nerve fiber bundles in the gold chloride staining model group were sparse, thinning, and shortening. The corneal nerve fibers were rich and in network structure in Chuyi Jiedu decoction and ganciclovir ophthalmic gel group. The nerve fiber bundles in the ganciclovir ophthalmic gel group were sparse and roughly in a network structure; Compared with the normal group, the CD4＋T cells decreased, the CD8＋T cells increased, and the CD4＋/CD8＋ decreased in model group （P〈0.01）; the Chuyi Jiedu decoction and ganciclovir ophthalmic gel group, and ganciclovir ophthalmic gel group compared with the model group, CD4＋T cells increased, CD8＋T cells decreased, CD4＋/CD8＋ increased, the difference was statistically
