摘要: 目的 研究复方鳖甲软肝片对二乙基亚硝胺(DEN)所致原发性肝癌大鼠肝癌组织增殖细胞核抗原(PCNA)和平滑肌肌动蛋白(α-SMA)表达的影响。方法 将40只SD大鼠随机平均分为对照组、模型组、大剂量和小剂量复方鳖甲软肝片处理组,每组均为10只。应用DEN注射法制备原发性肝癌模型,分别给予复方鳖甲软肝片0.625 g.kg-1和1.25 g.kg-1或生理盐水灌胃,连续给药20周。采用免疫组化法检测肝组织PCNA和α-SMA表达。结果 大剂量组肝脏质量、肝脏癌变率、肝脏指数和肝表面癌结节数分别为(17.34±1.78)g、10.0%、(3.10±0.72)和(3.16±0.45)个,显著低于模型组 【(25.59±2.38) g、100.0%、(4.95±0.58)和(14.14±2.37)个,P<0.05】;小剂量组肝脏质量、肝脏癌变率、肝脏指数和肝表面癌结节数分别为(19.89±1.80)g、30.0%、(3.89±0.81)和(7.38±1.01)个,也显著低于模型组(P<0.05);大剂量组PCNA和α-SMA相对表达量分别为(5.98±1.12)和(7.96±1.37),小剂量组分别为(9.23±1.34)和(12.34±2.88),均分别明显低于模型组【(19.59±2.67)和(25.12±3.19),P<0.05】。结论 复方鳖甲软肝片对DEN所致原发性肝癌大鼠具有较好的防治作用,可能是通过调节肝组织PCNA和α-SMA表达发挥作用的。

Abstract: Objective To observe the protective effect of Fufangbiejia, a herbal medicine, on diethylnitrosamine (DEN)-induced primary liver cancer (PLC) in rats and its impact on proliferating cell nuclear antigen (PCNA) and α-SMA expression. Methods 40 SD rats were randomly divided into control, model, high and low dose of herbal medicine-intervened groups, with 10 in each. The DEN was used to induce hepatic neoplasmas in rats, and the herbal medicine at dose of 0.625 g·kg-1 and 1.25 g·kg-1 or saline for gavage were given for 20 weeks. The PCNA and α-SMA were stained immunohistochemically. Results The liver weights, surface carcinoma nodule numbers, canceralization rates and liver index were (17.34±1.78) g, 10.0%, (3.10±0.72) and (3.16±0.45) in high dose group, significantly lower than in the model group 【(25.59±2.38) g, 100.0%,(4.95±0.58) and (14.14±2.37),P<0.05】; the liver weights, surface carcinoma nodule numbers, canceralization rates and liver index were (19.89±1.80)g, 30.0%, (3.89±0.81) and (7.38±1.01) in low dose group, also significantly lower than in the model group and(P<0.05);the expression scores of PCNA and α-SMA were (5.98±1.12) and (7.96±1.37) in high dose group,and (9.23±1.34) and (12.34±2.88) in low dose group, both significantly lower than in the model group 【(19.59±2.67) and (25.12±3.19),P<0.05】. Conclusions Fufangbiejia has a protective effect on DEN-induced primary liver cancer in rats, which might be related to the regulation of hepatic PCNA and α-SMA expression.
