摘　　要：目的探讨含笑内酯(MCL)对H22肝癌腹水瘤模型小鼠腹腔积液的治疗作用及机制。方法取H22肝癌腹水瘤细胞(0.2 m L,约2×10~7个)注射至40只BALB/C小鼠腹腔建立腹水瘤模型。接种24 h后小鼠随机分为MCL组[50 mg/(kg·d)MCL连续腹腔给药7 d]和模型组(等剂量生理盐水),每组20只。每日观察小鼠日常活动状态,记录小鼠体质量、腹围的变化。末次给药24 h后各组处死13只小鼠,采血后检测肿瘤标志物糖类抗原(CA)199、血清癌胚抗原(CEA)、铁蛋白、CA242、甲胎蛋白(AFP)水平;留取肝脏组织及腹水瘤细胞行HE染色,观察其病理状态;流式细胞术检测2组小鼠腹水瘤细胞凋亡情况。结果实验第4天开始,与模型组相比,MCL组体质量下降,腹围缩小(P<0.05)。与模型组比较,MCL组CEA、CA242、AFP水平出现下降,铁蛋白明显升高,肝组织及腹水瘤细胞水肿程度降低,腹水瘤细胞凋亡率升高(均P<0.05)。结论 MCL可抑制H22肝癌腹水瘤小鼠腹腔积液的生成,其机制可能是通过诱导肝癌细胞凋亡来实现的。Objective To investigate the therapeutic effect and mechanism of micheliolide(MCL)on peritoneal effusion in model mice with ascites tumor.Methods H22ascites mouse model was established by i.p.injecting H22cells(0.2mL,about2×107cells)in40BALB/C mice.Mice were randomly divided into MCL group(n=20,50mg/kg MCL once aday for7days)and model group(n=20,0.1mL/d normal saline once a day for7days).The daily data of bodyweights,abdominal circumference and behavior of the mice were observed and recorded.Thirteen mice were sacrificed at24hours after the last administration,and tumor markers(CA199,CEA,serum ferritin,CA242,AFP)were detected by ELISA.HEstaining was performed to observe the pathological changes of liver and ascites.The flow cytometry was used to detect theapoptosis of ascitic tumor cells in two groups.Results The bodyweights and abdominal circumference were decreasedsignificantly in MCL group than those in model group from the day four of experiment(P<0.05).Compared with the modelgroup,the levels of CEA,CA242and AFP were decreased in MCL group,while the serum ferritin was increased.At the sametime,the degree of diffuse edema of hepatocytes in the lobules and ascitic tumor cells was decreased in MCL group than thatin model group,but the apoptotic rate of ascitic tumor cells was elevated obviously in MCL group(P<0.05).Conclusion MCL has a significant inhibitory effect on H22ascites tumor bearing mice,and the mechanism is mainly through the induction of apoptosis of liver cancer cells.
