To compare the effects of Curcumae Rhizoma/vinegar-processed Curcumae Rhizomaon immune hepatic fibrosis, proliferation of HSC-T6, and expressions of α-SMA and Procollagen I. The immunological liver fibrosis model was prepared through intraperitoneal injection with porcine serum 0.5 mL in each rat, twice a week, for 14 weeks. Expressions of serum ALT, AST, PC-Ⅲ, IV-C, LN, HA and HYP, MDA in liver tissues were observed after administration of Curcumae Rhizoma/vinegar-processed Curcumae Rhizoma (0.95, 1.90 g•kg⁻¹). The pathological changes in liver tissues were observed by HE staining. Masson staining and Sirius red staining were used to observe the expression of collagen in rat liver. HSC-T6 was cultured, and the proliferation of HSC-T6 was determined by MTT assay at different concentrations in 12, 24, 36, 48 h. The expressions of α-SMA and Procollagen I were detected by Real-time PCR. The results showed that expressions of serum ALT, AST, PC-Ⅲ, IV-C, LN and HA in Curcumae Rhizoma/vinegar-processed Curcumae Rhizoma groups (0.95, 1.90 g•kg⁻¹) were significantly lower than model group; in terms of effect, vinegar-processed Curcumae Rhizoma group was superior to Curcumae Rhizoma group. Curcumae Rhizoma/vinegar-processed Curcumae Rhizoma containing serum could inhibit the proliferation of HSC-T6 in a dose-effect and time-effect manner. Expressions of α-SMA and Procollagen I in HSC-T6 were decreased after 24 h, especially in 20% vinegar-processed Curcumae Rhizoma containing serum group (P<0.01). Both Curcumae Rhizoma/vinegar-processed Curcumae Rhizoma could reduce immune hepatic fibrosis to varying extent. Their anti-hepatic fibrosis mechanism may be correlated with inhibition of the proliferation of HSC-T6, and reduction of the formation of extracellular matrix and promotion of its degradation.
比较姜黄/醋制姜黄对免疫性肝纤维化、肝星状细胞（HSC-T6）增殖及α-平滑肌肌动蛋白（α-SMA）和Ⅰ型胶原蛋白表达的影响。通过给每只大鼠腹腔注射0.5 mL猪血清制备免疫性肝纤维化模型，每周2次，共14周。给予姜黄/醋制姜黄（0.95、1.90 g•kg⁻¹）后，观察血清谷丙转氨酶（ALT）、谷草转氨酶（AST）、Ⅲ型前胶原（PC-Ⅲ）、Ⅳ型胶原（IV-C）、层粘连蛋白（LN）、透明质酸（HA）和羟脯氨酸（HYP）的表达以及肝组织中丙二醛（MDA）的含量。通过苏木精-伊红（HE）染色观察肝组织的病理变化。采用Masson染色和天狼星红染色观察大鼠肝脏中胶原蛋白的表达。培养HSC-T6，通过MTT法在12、24、36、48 h测定不同浓度下HSC-T6的增殖情况。通过实时荧光定量聚合酶链反应（Real-time PCR）检测α-SMA和Ⅰ型胶原蛋白的表达。结果显示，姜黄/醋制姜黄组（0.95、1.90 g•kg⁻¹）血清中ALT、AST、PC-Ⅲ、IV-C、LN和HA的表达均显著低于模型组；在作用效果方面，醋制姜黄组优于姜黄组。含药血清的姜黄/醋制姜黄能以剂量效应和时间效应方式抑制HSC-T6的增殖。24 h后HSC-T6中α-SMA和Ⅰ型胶原蛋白的表达降低，尤其是含20%醋制姜黄血清组（P<0.01）。姜黄/醋制姜黄均能不同程度减轻免疫性肝纤维化。其抗肝纤维化机制可能与抑制HSC-T6增殖、减少细胞外基质形成并促进其降解有关。
