Abdominal massage (AM), a traditional Chinese medicine-based treatment method, has received considerable attention in the recent years. The aim of the present study was to investigate the effect of AM on high-fat diet (HFD)-induced insulin resistance (IR) in comparison with resveratrol (RSV) treatment. Forty-eight male Sprague-Dawley rats were randomly divided into the following four groups: standard chow diet (control group), high-fat diet (model group), HFD + abdominal massage (AM group), and HFD + resveratrol (RSV group). A rat model of IR was established by feeding HFD to rats for 8 weeks followed by treatment with AM or RSV for 4 weeks. The underlying HFD-induced IR molecular mechanisms were studied in rat serum and skeletal muscles. RSV and AM significantly improved glucose intolerance, hyperglycemia, obesity, and significantly reduced lipid accumulation [triglyceride (TC), total cholesterol (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)], adipocytokine [free fatty acids (FFA), adiponectin (ADPN)] and serum pro-inflammatory cytokines (IL-6 and TNF-α) secretion. In addition, AM activated the AMPK/SIRT1 signaling pathway in rat skeletal muscle. In conclusion, our results showed that AM could improve IR by regulating the secretion of adipocytokines, pro-inflammatory cytokines as well as related signaling pathways in the skeletal muscle of rats, which might provide insights into development of new treatment methods for the clinical treatment of IR.
腹部按摩（AM）是一种基于中医的治疗方法，近年来受到了广泛关注。本研究旨在探讨 AM 对高脂肪饮食（HFD）诱导的胰岛素抵抗（IR）的影响，并与白藜芦醇（RSV）治疗进行比较。48 只雄性 Sprague-Dawley 大鼠随机分为以下四组：标准饲料饮食（对照组）、高脂肪饮食（模型组）、高脂肪饮食+腹部按摩（AM 组）和高脂肪饮食+白藜芦醇（RSV 组）。通过给予大鼠 HFD 8 周，然后用 AM 或 RSV 治疗 4 周，建立了大鼠 IR 模型。研究了 HFD 诱导的 IR 分子机制在大鼠血清和骨骼肌中的作用。RSV 和 AM 显著改善了葡萄糖耐量异常、高血糖、肥胖，并显著降低了脂质积累[甘油三酯（TC）、总胆固醇（TG）、低密度脂蛋白胆固醇（LDL-C）和高密度脂蛋白胆固醇（HDL-C）]、脂肪细胞因子[游离脂肪酸（FFA）、脂联素（ADPN）]和血清促炎细胞因子（IL-6 和 TNF-α）的分泌。此外，AM 还激活了大鼠骨骼肌中的 AMPK/SIRT1 信号通路。总之，我们的研究结果表明，AM 可以通过调节大鼠骨骼肌中脂肪细胞因子、促炎细胞因子及相关信号通路的分泌来改善 IR，这可能为开发新的治疗方法提供思路，用于临床治疗 IR。
