摘　　要：【目的】通过对不同脏腑虚损哮喘患者线粒体功能及其相关受损因素的分析,探寻不同脏腑虚损哮喘患者的病例特征,并通过对不同脏腑虚损组哮喘患者的线粒体功能变化及影响因素的差异性分析,试图发现不同脏腑虚损哮喘患者DDAH1/L-Arg/ADMA通路以及线粒体功能、氧代谢的变化趋势及规律。【方法】选取符合纳入标准的支气管哮喘急性发作期患者共122例,对入组患者进行临床资料采集,按脏腑虚损辨证分型标准分为肺气虚组47例、肺脾气虚组39例、肺脾肾虚组36例;并于同期选取正常对照组44例。观察不同脏腑虚损哮喘患者的第1秒用力呼气量(FEV1)、第1秒用力呼气量与用力肺活量的比值(FEV1/FVC)、呼气峰值流速(PEF)等肺功能指标和病情严重程度情况;同时,抽取患者静脉血,采用高效液相联合质谱法(HPLC-MS/MS)检测左旋精氨酸(L-Arg)及不对称二甲基精氨酸(ADMA)水平,采用酶联免疫吸附法(ELASA)检测蛋白精氨酸甲基转移酶1(PRMT1)、二甲基精氨酸二甲氨基水解酶1(DDAH1)等精氨酸代谢相关指标及活性氧自由基(ROS)、硫代巴比妥酸反应产物(TBARS)、8-异前列腺素(8-Iso)、过氧化脂质(LPO)、丙二醛(MDA)等氧化损伤标记物水平;提取哮喘患者及正常对照组的血小板及线粒体,JC-1流式细胞法测定血小板线粒体膜电位(MMP)、三磷酸腺苷(ATP)和细胞色素C氧化酶(COX)的活性,以此评估线粒体功能;分析不同脏腑虚损组哮喘患者的线粒体功能变化及影响因素的差异性,并与正常对照组比较。【结果】(1)不同脏腑虚损哮喘患者的年龄和肺功能(FEV1、FEV1/FVC、PEF)比较,差异均有统计学意义(P<0.01)。表现为肺脾肾虚组的年龄明显高于肺气虚组和肺脾气虚组(P<0.05),以及随脏腑虚损情况的加重,肺功能(FEV1、FEV1/FVC、PEF)呈显著下降趋势(P<0.05)。(2)不同脏腑虚损患者的病情严重程度分布比较,差异有统计学意�Objective To investigate the clinical characteristics of asthma patients with deficiency of various viscera through the analysis of mitochondrial dysfunction and related influencing factors,and to explore the DDAH1/L-Arg/ADMA pathway as well as the trend of changes in the mitochondrial function and oxygen metabolism of the asthma patients through the analysis.Methods A total of 122 patients with acute exacerbation of bronchial asthma who met the inclusion criteria were selected,and their clinical data were collected.The patients were divided into 3 groups based on the criteria of visceral deficiency syndrome differentiation,namely lung qi deficiency group(47 cases),lung-spleen qi deficiency group(39 cases),and lung-spleen-kidney deficiency group(36 cases).Meanwhile,the normal control group including 44 cases was set up.For the asthma patients with visceral deficiency,an observation was conducted in the lung function indicators of forced expiratory volume in the first second(FEV1),the ratio of FEV1 to forced vital capacity(FEV1/FVC)and peak expiratory flow(PEF)as well as the severity of the disease.Moreover,venous blood was sampled from the patients for the detection of L-arginine(L-Arg)and asymmetric dimethylarginine(ADMA)levels with high-performance liquid chromatography coupled with mass spectrometry(HPLC-MS/MS),and for the detection of arginine metabolism related indicators of protein arginine methyltransferase 1(PRMT1)and dimethylarginine dimethylammonium hydrolysate 1(DDAH1)as well as the oxidative damage parameters of reactive oxygen species(ROS),thiobarbituric acid reactive substance(TBARS),8-iso-prostaglandins(8-iso),lipid peroxide(LPO),and malondialdehyde(MDA)with enzyme-linked immunosorbent assay(ELISA).The platelet mitochondria were extracted from asthma patients and normal controls,and then the mitochondrial membrane potential(MMP),adenosine triphosphate(ATP),and activities of cytochrome C oxidase(COX)in the platelet were determined by JC-1 flow cytometric assay in order to assess the mitochondrial fu
