摘要:

目的 探讨寡肽中草药复合制剂的减肥功效及其机制,为肥胖治疗提供新思路。 方法 将23只SPF级雌性SD大鼠随机分为对照组(3只)和造模组(20只),对照组连续6周饲喂普通饲料,造模组连续6周高脂饮食诱导构建单纯性肥胖大鼠模型。造模成功后,随机将造模组分为模型组(10只)和治疗组(10只),治疗组开始通过膏摩寡肽中草药复合制剂(3 g/只/次,1天1次,1次20 min)记作第1天,对照组和模型组不作寡肽中草药复合制剂处理但施以相同的按摩处理,并分别继续饲喂普通饲料和高脂饲料。将模型组和治疗组各10只大鼠分别分为3组,每组为3、3、4只,分别于治疗后第3、6、9天将3组大鼠经异氟烷呼吸麻醉后称重并行心脏采血,继续心脏放血法安乐死后采集腹部皮下脂肪组织(abdominal subcutaneous adipose tissue,aSAT)和肾周白色脂肪组织(perirenal white adipose tissue,pWAT)样本并称重。检测血清甘油三酯(triglycerides,TG)和高密度脂蛋白胆固醇(high-density lipoprotein cholesterol,HDL-C)水平。用Image J软件测量腹部皮下脂肪组织厚度、肾周白色脂肪细胞以及腹部皮下脂肪细胞直径和面积;通过免疫荧光技术观察腹部皮下脂肪组织单位面积的特络细胞(telocytes,TCs)、细胞连接、外泌体数量;通过透射电子显微镜统计腹部皮肤真皮及皮下TCs突起(telopodes,Tps)长度,并观测外泌体囊泡、粗面内质网、线粒体、细胞连接的分布。 结果 与对照组相比,造模组大鼠的体重显著增加(P<0.05)。与对照组相比,模型组大鼠血清TG水平显著升高,HDL-C水平显著降低,肾周白色脂肪组织质量显著增加(均P<0.05)。与模型组相比,治疗组大鼠的体重下降率显著增高,肾周白色脂肪组织质量显著降低,血清TG水平显著降低,HDL-C水平显著升高(均P<0.05)。与模型组相比,治疗组腹部皮下脂肪组织厚度、腹部皮下脂肪与肾周白色脂肪组织的细胞直径和面积显著减小(均P<0.05)。与模型组相比,治疗组腹部皮下脂肪组织单位面积TCs数量、腹部皮下脂肪组织TCs外泌体数量、Tps长度显著增加(均P<0.05);治疗组TCs细胞内线粒体、粗面内质网,细胞连接数均有增多趋势。 结论 膏摩寡肽中草药复合制剂通过调节TCs及其细胞间通讯,有效改善肥胖大鼠的血脂紊乱和脂肪堆积等肥胖相关症状。

Abstract:

Objective To investigate the weight loss efficacy and mechanisms of oligopeptide-herbal medicine composite, and to provide new approaches for obesity treatment. Methods Twenty-three SPF female SD rats were randomly divided into control group (n=3) and modeling group (n=20). The control group was fed an ordinary diet for 6 consecutive weeks, and the modeling group was fed a high-fat diet for 6 consecutive weeks to establish a simple obesity rat model. After successful modeling, the modeling group was randomly divided into model group (n=10) and treatment group (n=10). The treatment group started anoint-and-massage therapy with oligopeptide-herbal medicine composite (3 g per rat per time,once a day, 20 min each time), which was recorded as day 1. The control group and model group were not treated with oligopeptide-herbal medicine composite but received the same massage, and continued to be fed ordinary feed and high-fat feed respectively. Ten rats in the model group and ten in the treatment group were each divided into 3 groups, with 3, 3, and 4 rats in each group. On days 3, 6, and 9 after treatment, the rats in the three groups were weighed and cardiac blood collection was performed after isoflurane respiratory anesthesia. After euthanasia by cardiac bloodletting, abdominal subcutaneous adipose tissue (aSAT) and perirenal white adipose tissue (pWAT) samples were collected and weighed. Serum triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C) levels were measured. Image J software was used to measure aSAT thickness and the diameter and area of perirenal white adipocytes and abdominal subcutaneous adipocytes. Immunofluorescence technique was used to observe the number of telocytes (TCs), cell junctions and exosomes per unit area of aSAT. Transmission electron microscopy was used to measure the length of telopodes (Tps) of dermal and subcutaneous TCs in abdominal skin, and to observe the distribution of exosome vesicles, rough endoplasmic reticulum, mitochondria, and cell junctions. Results Compared with the control group, the body weight of rats in the modeling group increased significantly (P<0.05). Compared with the control group, rats in the model group showed a significant increase in serum TG level, a significant decrease in HDL-C level, and a significant increase in pWAT mass (all P<0.05). Compared with the model group, the treatment group showed a significantly increased rate of body weight reduction, significantly decreased pWAT mass, significantly decreased serum TG level, and significantly increased HDL-C level (all P<0.05). Compared with the model group, the treatment group showed significant reductions in aSAT thickness, as well as cell diameter and area in both aSAT and pWAT (all P<0.05). Compared with the model group, the treatment group showed significantly increased number of TCs per unit area of aSAT, number of exosomes from TCs in aSAT, and Tps length (all P<0.05). The treatment group showed an increasing trend in the numbers of mitochondria, rough endoplasmic reticulum, and cell junctions in TCs. Conclusion Oligopeptide-herbal medicine composite applied via anoint-and-massage therapy effectively improves obesity-related symptoms such as dyslipidemia and fat accumulation in obese rats by regulating TCs and their intercellular communication.
