摘　　要：目的研究温阳化浊通络方基于线粒体自噬对硬皮病小鼠肺微血管损伤的影响。方法将50只小鼠随机分为空白对照组(0.9%NaCl,灌胃)、对照组(0.9%NaCl,灌胃)、模型组(0.9%NaCl,灌胃)、温阳化浊通络方组(47 mg·kg^(-1)·d^(-1)温阳化浊通络方,灌胃)、阳性对照组(10 mg·kg^(-1)·d^(-1)KC7F2溶解于磷酸盐缓冲液,腹腔注射),持续给药4周。以免疫组化法检测肺组织线粒体外膜易位酶20(TOMM20)及缺氧诱导因子-1α(HIF-1α)、B细胞淋巴瘤-2/腺病毒E1B-19kDa相互作用蛋白3(BNIP3)、PTEN诱导性肌酶蛋白1(PINK1)、E3泛素连接酶(Parkin)的表达水平;以蛋白质印迹(Western blot,WB)法检测肺组织微血管内皮细胞线粒体自噬相关蛋白TOMM20、LC3B及HIF-1α/BNIP3/PINK1/Parkin通路蛋白表达水平。结果对照组、模型组、温阳化浊通络方组和阳性对照组小鼠肺组织微血管内皮细胞HIF-1α相对含量分别为0.17±0.02、0.98±0.01、0.66±0.03和0.48±0.01,BNIP3相对含量分别为0.40±0.02、0.74±0.01、0.56±0.01和0.60±0.02,PINK1相对含量分别为0.26±0.04、0.88±0.01、0.65±0.02和0.67±0.02,Parkin相对含量为分别为0.33±0.02、0.89±0.01、0.65±0.02和0.77±0.02,TOMM20相对含量分别为1.10±0.02、0.58±0.01、1.02±0.01和0.98±0.03,LC3B-Ⅰ/LC3B-Ⅱ相对含量分别为0.24±0.01、0.80±0.01、0.53±0.02和0.70±0.02。模型组中HIF-1α、BNIP3、PINK1、Parkin、LC3B-Ⅰ/LC3B-Ⅱ蛋白含量高于对照组,温阳化浊通络方可有效降低其含量;模型组中TOMM20含量低于对照组,温阳化浊通络方可有效提高其含量。结论温阳化浊通络方可能通过增加TOMM20和抑制LC3B及HIF-1α/BNIP3/PINK1/Parkin信号通路的蛋白表达,进而抑制线粒体自噬,改善SSc肺微血管损伤。Objective To explore the effect of Wenyang Huazhuo Tongluo recipe on pulmonary microvascular injury in mice with scleroderma based on mitophagy.Methods Fifty mice were randomly divided into blank control group(0.9%NaCl,by gavage),control group(0.9%NaCl,by gavage),model group,Wenyang Huazhuo Tongluo recipe group(47mg·kg^(-1)·d^(-1)Wenyang Huazhuo Tongluo recipe by gavage),positive control group(10 mg·kg^(-1)·d^(-1)KC7F2 dissolved in phosphate buffer solution intraperitoneal injection),continuous administration for 4 weeks.The expression levels ofin vitromembrane translocation enzyme 20(TOMM20),hypoxia inducible factor-1α(HIF-1α),B cell lymphoma-2/adenovirus E1B-19 kDa interacting protein 3(BNIP3),PTEN inducible muscle enzyme protein 1(PINK1)and E3 ubiquitin ligase(Parkin)in lung tissue were detected by immunohistochemistry(IHC).Western blot(WB)was used to detect the expression levels of mitophagy-related proteins(TOMM20,LC3B)and HIF-1α/BNIP3/PINK1/Parkin pathway proteins in pulmonary microvascular endothelial cells.Results The relative content of HIF-1αin microvascular endothelial cells of lung tissue in the control group,model group,Wenyang Huazhuo Tongluo recipe group and positive control group were 0.17±0.02,0.98±0.01,0.66±0.03 and 0.48±0.01;the relative content of BNIP3 were 0.40±0.02,0.74±0.01,0.56±0.01 and 0.60±0.02;the relative content of PINK1 were 0.26±0.04,0.88±0.01,0.65±0.02 and0.67±0.02;the relative contents of Parkin were 0.33±0.02,0.89±0.01,0.65±0.02 and 0.77±0.02;the relative contents of TOMM20 were 1.10±0.02,0.58±0.01,1.02±0.01 and 0.98±0.03;the relative contents of LC3B-Ⅰ/LC3B-Ⅱwere 0.24±0.01,0.80±0.01,0.53±0.02 and 0.70±0.02,respectively.The content of HIF-1α,BNIP3,PINK1,Parkin and LC3B-Ⅰ/LC3B-Ⅱin model group was higher than those in control group.Wenyang Huazhuo Tongluo recipe can effectively reduce its content.The content of TOMM20 in the model group was lower than that in control group,and Wenyang Huazhuo Tongluo recipe can effectively increase its cont
