【摘要】 脂肪肝(Fatty Liver,FL.;Steatosis)是由各种原因引起的肝细胞内脂肪异常增加的病理征象,当肝细胞内脂质超过肝湿重的5%,或组织学上每单位面积见1/3以上肝细胞脂变时,即可称为脂肪肝。脂肪肝中医辨证多属“胁痛”、“积聚”等病范畴。二十世纪八十年代末,日、美等学者用B超普查发现脂肪肝发病率约占平均人口的10%,且因各方面原因,近年来本病发病率仍在上升,患者群日趋年轻。诸多研究表明,虽然脂肪肝尚属可逆性病变,但如果长期失治、误治,可导致肝纤维化、肝硬化等疾患。故尔,对其进行深入研究,寻求有效的治疗方法,提高治疗效果,无疑具有重大的社会意义和深入研究中医药的实际意义。 本课题旨在通过古今文献研究、动物实验,进行配伍研究,从方剂学角度,阐明活血、行气、健脾法配伍组方治疗脂肪肝的合理性及不同治法拆方配伍之间的联系。 古今文献研究表明,脂肪肝病因病机多因肝郁气滞,饮食伤脾、脾虚湿停,并由气滞湿停而致瘀血留滞,终成瘀血、气滞、停湿相兼为患。祖国医学对本病的治疗,多用活血、行气、健脾等法治疗,每能取得良好效果。 在实验研究中,观察了全方、阳性对照药及各拆方组对脂肪肝模型大鼠肝脏病理脂肪变性、血清甘油三酯(TG)、总胆固醇(TC)、血清中高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、游离胆固醇(FC)、载脂蛋白Al、载脂蛋白B、肝组织TG、TC含量以及全血粘度的影响。其结果表明:行气活血健脾法组方能显著改善脂肪肝模型大鼠肝脏脂肪变,作用优于阳性对照药东宝肝泰。对模型大鼠TG、TC,肝组织TG、TC,全血粘度等指标的改善,全方组作用最明显,各拆方实验结果表明,不同治法之间,其作用并非简单相加,而是一种协同作用,从而印证了方剂配伍之要妙。 黑龙江中医药大学博士学位论文 在此基础上进行了全方作用机理的探讨,从抑制外源性胆固 醇的吸收、抑制内源性胆固醇的生成、保护肝功能、促进胆固醇 从肝脏中转运几个方面做了初步实验。本方可明显增加血清中载 脂蛋白的含量,明显降低由于化学损伤引起的肝脏转氨酶的升高 和改变血粘度的作用。而阻止从肠内吸收的作用不明显。由于脂 类代谢的复杂性,似可认为本方具有促进脂类从肝脏转运的作用, 同时具有明显的保护肝功能的作用,其具体机理尚有待进一步研 究证实。 结合药理学指标,对所选择的方剂进行了有效部位的筛选, 认为其中的醇提取药效最强。提取的中药用石油醚、乙酸乙酯和 正丁醇进行荐取分离,认为乙酸乙酯部分药效最强。

【Abstract】 Fatty liver is accumulation of fat in liver because of sorts of reason when over 5% of weight or 1/3 in area.It belongs to Hypochondriac Pain, Mass, etc. in TCM. In the late 1980s, scholars of America and Japan found that the incidence of this disease is about 10 percent of the population, through general survey with B-mode ultrasonic diagnostic equipment. And for all sorts of reasons, recently the incidence of fatty liver is increasing, and the age of the sufferers is becoming younger and younger. Without promptly treatments or with erroneous treatments, fatty liver, a reversible disease may develop and be transformed into hepatic fibrosis, cirrhosis. Therefore, the further study of the disease, the quest of the effective therapy, the raise of the curative effect, certainly has great social significance and practical significance of study of TCM.This subject aims at explicating from the angle of recipe course, about the rationality of the prescription according to the therapeutic methods of Activating Blood Circulation,Promoting the circulation of Qi, and Invigorating Spleen..The document research shows that, the pathogenesis of fatty liver mostly relates to Blood Stasis, Stagnation of the Liver-Qi and Water Retention due to Deficiency of the Spleen. In TCM therapeutics, Dispersing Stagnated Liver-Qi, Invigorating the Spleen Removing Dampness, Activating Blood Circulation to Dissipate Blood Stasis, regularly proves effective.During the experiment, we observed the model rats treated with different components. The result of shows that, the prescription composed according to the therapeutic methods of Activating BloodCirculation, Regulating Qi, Removing Dampness can distinctly ameliorate the hepatic steatosis of the model mice. Different therapeutic methods, when making up with one another, have particular inner link.
