夏枯草消瘤合剂对Lewis肺癌小鼠的药效作用

目的 探讨夏枯草消瘤合剂对Lewis肺癌小鼠的治疗作用。方法 采用C₅₇BL/6小鼠Lewis肺癌移植瘤模型，将30只小鼠随机分为3组：模型对照组、夏枯草消瘤合剂组（M组）、顺铂组（DDP组），连续用药14 d。通过对Lewis肺癌小鼠的大体观察，测定肿瘤大小，HE染色方法测定肿瘤病理组织学变化，免疫组化方法测定肿瘤组织的细胞周期蛋白D1（CyclinD1）和P16的表达情况。结果 模型对照组瘤体质量最重，与其他组比较差异均有统计学意义（P<0.05）；M组可在一定程度上改善小鼠的生存状态及生活质量；各组小鼠的肿瘤生长曲线及HE染色结果显示：M组可抑制肿瘤细胞的生长，且对正常细胞有保护作用；M组、DDP组均可显著降低CyclinD1阳性表达（P<0.01），但是M组对于提高P16阳性表达的效果不显著。结论 夏枯草消瘤合剂具有较好的抑制肺癌生长的作用。

Therapeutic effect of Xiakucao Xiaoliu mixture on Lewis lung cancer mice

Objective To investigate the therapeutic effect of Xiakucao Xiaoliu mixture on Lewis lung cancer mice.Methods 30 mice with C₅₇BL/6 mouse Lewis lung cancer xenograft model were randomly divided into three groups:model control group, Xiakucao Xiaoliu mixture group (M group), cisplatin group (DDP group). M group and DDP group were administered continuously for 14 days. Through the general observation of Lewis lung cancer mice, tumor size was determined, HE staining method was used to determine the histopathological changes of tumors, and the expression of CyclinD1 and P16 in tumor tissues was determined by immunohistochemistry.Results The tumor weight of the model control group was the heaviest, and the difference was statistically significant compared with other groups. (P<0.05). Survival state and quality of life of mice had been improved to some extent in M group. The results of tumor growth curve and HE staining in each group of mice showed that the growth of tumor cells had been inhibited and normal cells had been protected. The positive expression of CyclinD1 was significantly decreased in M group and DDP group (P<0.01), but the effect of M group on the improvement of P16 positive expression was not significant.Conclusion Xiakucao Xiaoliu mixture had a good effect on inhibiting lung tumor growth.
