摘 要 目的 探讨乌梅抗肝纤维化(HF)的作用及机制。方法 将雄性SD大鼠随机分为正常对照组(n=10)与造模组(n=50),
造模组大鼠以四氯化碳诱导建立HF模型。将成模大鼠分为模型组(生理盐水)、阳性对照药组[秋水仙碱,0.09 mg/(kg·d)]及乌梅
低、中、高剂量组[1.35、2.70、5.40 g/(kg·d)],每组9只。大鼠每天灌胃相应药物/生理盐水1次,持续8周。末次给药后,计算大鼠肝

变、Masson 染色法观察大鼠 HF 程度、透射电镜法观察大鼠肝组织超微结构、TUNEL 染色法检测大鼠肝细胞凋亡水平,并采用
Western blot 法检测大鼠肝组织中转化生长因子 β1 (TGF-β1 )、血小板源性生长因子(PDGF)蛋白的表达。结果 与正常对照组相

较,乌梅各剂量组大鼠上述指标均有不同程度改善,其中乌梅中、高剂量组大鼠上述指标均被显著逆转(P<0.05或P<0.01)。结论
乌梅具有抗HF的作用,该作用可能是通过抗氧化、抗炎、减少胶原产生、抑制PDGF表达及调控TGF-β1信号通路等机制实现的。

ABSTRACT OBJECTIVE To explore the effect and mechanism of Prunus mume against hepatic fibrosis (HF). METHODS
Male SD rats were randomly divided into normal control group (n=10) and modeling group (n=50). The modeling group
established HF model using carbon tetrachloride. The modeled rats were randomly divided into model group (normal saline),
positive control group [colchicine, 0.09 mg/(kg·d)], and P. mume low-dose, medium-dose and high-dose groups [1.35, 2.70, 5.40
g/(kg·d)], with 9 rats in each group. They were given the corresponding drug/normal saline intragastrically, once a day, for 8
consecutive weeks. After the last medication, the liver index was calculated, while liver function indexes, liver fiber indexes,
oxidative stress indicators and inflammatory factors of rats were measured. HE staining was used to observe the pathological
changes in liver tissue of rats; Masson staining was used to observe the degree of HF in liver tissue of rats; transmission electron
microscopy was used to observe the ultrastructure of liver tissue in rats; TUNEL staining was used to detect liver cell apoptosis in
each group of rats. Western blot method was used to detect the protein expressions of transforming growth factor-β1 (TGF-β1 ) and
platelet-derived growth factor (PDGF) in liver tissue of rats. RESULTS Compared with normal control group, the levels of alanine
transaminase, alkaline phosphatase, aspartate transaminase, total bilirubin, malondialdehyde, procollagen type Ⅲ protein, Ⅳ-type
pre collagenase, laminin, hyaluronic acid, interleukin-6, tumor necrosis factor-α, as well as the protein expressions of TGF-β1 and
PDGF in model group were increased significantly, while the levels of superoxide dismutase and glutathione peroxidase were
significantly reduced (P<0.01); the HE, Masson staining and transmission electron microscopy observation results showed
obvious HF characteristics in rats of model group. Compared
