目的 探究单次肝区推拿对急性酒精性肝损伤小鼠的影响。方法 24只8周龄C57BL/6雄性小鼠,随机分为空白组、模型组、6小时推拿组和24小时推拿组,每组6只。通过两次间隔12小时灌胃75%乙醇(每次12 μL/g)建立急性酒精性肝损伤模型。在造模后对6小时推拿组和24小时推拿组进行5分钟单次肝区推拿。根据干预后取材时间点不同,分别在6小时(模型组、空白组和6小时推拿组)和24小时(24小时推拿组)后取材。计算小鼠体质量和肝脏质量的比值;检测小鼠血清中丙氨酸氨基转移酶(alanine aminotransferase,ALT)、天冬氨酸氨基转移酶(aspartate aminotransferase,AST)、甘油三酯(triglyceride,TG)、高密度脂蛋白胆固醇(high-density lipoprotein cholesterol,HDL-C)、低密度脂蛋白胆固醇(low-density lipoprotein cholesterol,LDL-C)以及小鼠肝匀浆中超氧化物歧化酶(superoxide dismutase,SOD)、谷胱甘肱(glutathione,GSH)、丙二醛(malondialdehyde,MDA)的水平;采用苏木素—伊红(hematoxylin-eosin,HE)染色法观察肝组织形态;油红染色观察肝细胞脂肪变性。结果 (1)肝脏指数、AST、ALT:与空白组相比,模型组肝脏指数、ALT、AST升高(P<0。05)。与模型组相比,6小时推拿组ALT、AST降低(P<0。05)。24小时推拿组肝脏指数、ALT、AST降低(P<0。05)。(2)HE染色:模型组肝细胞显示肝索排列混乱,肝小叶结构受损。6小时推拿组和24小时推拿组的肝细胞病变数量显著减少,肝索排列更为规整。(3)TG、HDL-C、LDL-C:与空白组相比,模型组的TG升高(P<0。05),HDL-C降低(P<0。05)。与模型组相比,6小时推拿组的TG降低(P<0。05),HDL-C升高(P<0。05);24小时推拿组的TG、LDL-C降低(P<0。05),HDL-C升高(P<0。05)。(4)油红染色:模型组肝细胞中脂滴增多,6小时推拿组和24小时推拿组的脂肪变性程度明显减轻。(5)GSH、MDA、SOD:与空白组相比,模型组的GSH降低(P<0。05),SOD升高(P<0。05)。与模型组相比,6小时推拿组和24小时推拿组的GSH、MDA、SOD无显著差异(P>0。05)。结论 单次肝区推拿干预对急性酒精性肝损伤小鼠肝脏具有保护作用,且效果具有持续性。单次肝区推拿能改善急性酒精性肝损伤小鼠的肝功能指标和血脂水平,减轻肝脏病理损伤,降低肝细胞脂肪变性。
Exploring the effect of single abdominal massage on acute alcoholic liver injury in mice
Objective This study aims to explore the effects of a single session of hepatic area massage on mice with acute alcoholic liver injury.Methods Twenty-four 8-week-old male C57BL/6 mice were randomly divided into four groups:the control group,the model group,the 6-hour massage group,and the 24-hour massage group,with six mice in each group.Acute alcoholic liver injury was induced by administering 75%ethanol via gavage at a dose of 12 μL/g twice,with a 12-hour interval between adminis-trations.After the model was established,the mice in the 6-hour and 24-hour massage groups received a single 5-minute hepatic area massage.Tissue samples were collected 6 hours post-intervention from the model,control,and 6-hour massage groups,and 24 hours post-intervention from the 24-hour massage group.Liver-to-body weight ratios were calculated;The levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),superoxide dismutase(SOD),glutathione(GSH),and ma-londialdehyde(MDA)in serum and liver homogenates were measured.The liver tissue morphology was observed using hematoxylin-eosin(HE)staining,and fat degeneration in liver cells was examined with Oil Red O staining.Results(1)Compared with the control group,the levels of liver indices,AST,ALT in the model group were increased(P<0.05).The 6-hour massage group exhibited reduced ALT and AST levels compared with the model group(P<0.05),and the 24-hour massage group showed reductions in liver index,ALT,and AST(P<0.05).(2)HE staining:Liver cells in the model group displayed disorganized hepatic cords and damaged lobular structures.Both the 6-hour and 24-hour massage groups showed significant reductions in liver cell damage,with more organized hepatic cords.(3)Compared with the control group,the model group exhibited increased TG and decreased HDL-C(P<0.05).The 6-hour massage group showed decreased TG and increased HDL-C(P<0.05),while the 24-hour massage group had reduced TG and LDL-C,and increased HDL-C(P<0.05).(4)There was an increase in lipid droplets in liver cells of the model group,while the extent of fatty degeneration was significantly reduced in both the 6-hour and 24-hour massage groups.(5)The model group showed decreased GSH and increased SOD levels compared with the control group(P<0.05).No significant differences were observed in the levels of SOD,MDA,or GSH levels between the massage groups and the model group(P>0.05).Conclusion Single session hepatic area massage offers protective effects against acute alcoholic liver injury in mice and improves liver function markers and lipid levels,reducing pathological liver damage and fatty degeneration of liver cells.The effects are durable,demonstrating the potential therapeutic benefits of this intervention.
