文题释义:
微循环:是物质交换的重要场所,人体的细胞、组织及器官只有在微循环血液正常灌流下才能维持正常的生理功能,微循环障碍是多种疾病发生前的先期病变和最基本的病理改变。
肝纤维化:是由于各种损肝因素所致的肝脏内纤维结缔组织异常增生的病理过程。
摘要
背景
:中药复方柔肝化纤颗粒已证明能显著改善慢性肝炎、肝硬化患者的临床症状,但其能否多途径、多靶点、多环节改善肝脏微循环尚不明确。
目的:构建肝纤维化大鼠模型,观察中药复方柔肝化纤颗粒全方及不同拆方组合对模型大鼠肝脏微循环障碍失衡的影响及差异。
方法:采用CCl4复合因素造模方法复制肝纤维化大鼠模型,在第4周造模结束后将建模成功的大鼠随机为6组:模型组、大黄蟅虫丸组,柔肝化纤颗粒组1:柔肝化纤颗粒全方灌胃;柔肝化纤颗粒组2:予补肾养肝方灌胃;柔肝化纤颗粒组3:予益气健脾方灌胃;柔肝化纤颗粒组4:予化痰解毒方与活血化瘀、软坚散结方灌胃;同时设正常对照组进行对比,各组分别按0.1 mL/kg灌胃给予相应的药液,1次/d,共给药12周。
结果与结论:①光学显微镜下观察,模型组肝间质出现广泛纤维组织增生,将正常肝小叶分割成大小不等的肝细胞团(即假小叶形成),说明肝纤维化模型大鼠造模成功;②与正常对照组比较,各组大鼠血清一氧化氮及内皮素1水平明显偏高,且肝硬化程度越高,一氧化氮及内皮素1水平增高越明显(P < 0.01),而肝动脉始增时间、肝静脉始增时间的缩短越明显(P < 0.05或P < 0.01);③与模型组比较,各用药组血清一氧化氮及内皮素1水平均有不同程度的降低(P < 0.01),各用药组肝动脉始增时间、肝静脉始增时间均有不同程度的延长(P < 0.01);④与黄蟅虫丸组相比,柔肝化纤全方组的一氧化氮及内皮素1水平均显著降低(P < 0.05或P < 0.01),肝静脉始增时间较黄蟅虫丸组延长(P < 0.01);⑤结果说明,实验成功复制了肝纤维化模型大鼠,采用中药复方柔肝化纤颗粒全方干预治疗后,能够调节模型大鼠肝脏微血管的流速,促进肝脏微循环的血流灌注量,有助于延缓肝纤维化的进展,其机制可能主要通过降低血清一氧化氮及内皮素1水平有关。

Abstract:

BACKGROUND: Chinese herbal compound Rougan Huaxian Granule has been shown to improve chronic hepatitis and liver fibrosis. However, whether it can improve liver microcirculation in multi-path, multi-target and multiple-link remains unclear.
OBJECTIVE: To investigate the effects and differences of Rougan Huaxian Granule and its disassembled formulas on the regulation of microcirculation disturbance in model rat liver.
METHODS: The rat model of liver fibrosis was established by CCl4 compound factors. Four weeks later, the model rats were randomized into six groups: model group, Dahuang Zhechong Pill group, Rougan Huaxian Granule 1, 2, 3 and 4 groups, treated with Rougan Huaxian Granule, Bushen Yanggan Formula, Yiqi Jianpi Foamula and Huatan Jiedu Formula, Huoxue Huayu Formula combined with Ruanjian Sanjie Formula, respectively. The remaining normal rats were used as control group. The drug (0.1 mL/kg) was given via gavage, once daily for 12 weeks.
RESULTS AND CONCLUSION: Light microscopy showed that fibrous hyperplasia occurred in the liver mesenchyma, which divided the normal hepatic lobules into uneven cell masses (pseudolobule formation), suggesting the live fibrosis model was established successfully. Compared with the control group, the serum levels of NO and endothelin-1 were significantly increased in each group. With the progression of liver cirrhosis, the levels of NO and endothelin-1 were decreased significantly (P < 0.01), and the hepatic artery/vein activation time was shortened significantly (P < 0.05 or P < 0.01). Compared with the model group, the contents of NO and endothelin-1 in each treatment group were decreased in different degrees (P < 0.01), and the hepatic artery/vein activation time was prolonged (P < 0.01). Compared with Dahuang Zhechong Pill group, the contents of NO and endothelin-1 in Rougan Huaxian group 1 were significantly decreased (P < 0.05 or P < 0.01), and the hepatic vein activation time was prolonged (P < 0.01). In summary, the rat model of live fibrosis is successfully constructed. Rougan Huaxian Granule can promote the microcirculation of the liver and increase the hepatic microvascular flow rate, and delay the development of liver fibrosis. The mechanism may be related to the decrease in serum levels NO and endothelin-1.
