摘　　要：目的:分析血乳酸、纤维母细胞生长因子21(FGF21)在儿童线粒体脑肌病(ME)诊断与疗效监测中作用及意义。方法:按照1∶1∶1选取2020年8月至2023年2月昆明市儿童医院收治的47例儿童ME患儿(ME组)、47例非线粒体病的肌肉病患儿(肌肉病组)及47例健康儿童(对照组)。给予ME患儿饮食和运动指导、左乙拉西坦、艾地苯醌、维生素C、叶酸、辅酶Q10等对症治疗,治疗后3个月评估疗效,根据疗效将ME患儿分为控制与未控制亚组。治疗前、治疗后1个月和3个月留取空腹血标本,以美国YSI 1500 SPORT型血乳酸分析仪及配套试剂盒检测血乳酸水平,以酶联免疫吸附法及酶标仪检测血清FGF21水平。比较3组治疗前血乳酸、FGF21,使用交互作用系数γ与OR值分析血乳酸、FGF21对儿童ME易感性影响的交互作用,受试者工作特征曲线(ROC)分析血乳酸、FGF21诊断儿童ME的价值,并比较ME不同疗效患儿治疗前、治疗后1个月和3个月血乳酸、FGF21、Newcastle线粒体病评分量表(NMDAS)评分变化,Pearson分析治疗后1个月和3个月血乳酸、FGF21降低值与NMDAS评分降低值相关性。结果:与对照组相比,ME组血乳酸、FGF21升高(t=13.901、38.082,P<0.05);与肌肉病组相比,ME组血乳酸、FGF21升高(t=12.734、35.696,P<0.05);对照组、肌肉病组血乳酸、FGF21相比,无明显差异(t=0.821、1.326,均P>0.05);交互作用分析显示,血乳酸、FGF21共存所致OR值为1350.500,回归系数为7.208,交互作用OR值<两单独因素OR值的乘积,为次相乘模型,γ=1.535>1,血乳酸对FGF21的效应具有正向交互作用;ROC曲线显示,血乳酸+FGF21诊断儿童ME的AUC为0.904,高于血乳酸的0.839及FGF21的0.719,其诊断敏感度为78.72%,特异度为87.23%;病情获得控制患儿治疗后1个月、治疗后3个月血乳酸、FGF21、NMDAS评分低于未控制患儿(P<0.05);相关性分析显示,血乳酸、FGF21治疗后1个月降低值、治疗后3个月降低值与NMDAS评分治疗后Objective:To analyze the role and significance of blood lactate and fibroblast growth factor 21(FGF21)in the diagnosis and efficacy monitoring of mitochondrial myopathy(ME)in children.Methods:A total of 141 subjects were enrolled in this study,including 47 children with ME(ME group),47 children with non-mitochondrial myopathies(muscle disease group),and 47 healthy children(control group),all of whom were admitted to Kunming Children's Hospital from August 2020 to February 2023.The ME group received dietary and exercise guidance,lamotrigine,idebenone,vitamin C,folic acid,and coenzyme Q10 for treatment.The efficacy was evaluated 3 months after treatment,and the ME patients were divided into controlled and uncontrolled subgroups according to the efficacy.Fasting blood samples were collected before treatment,1 month after treatment,and 3 months after treatment.Blood lactate levels were measured using the American YSI 1500 SPORT blood lactate analyzer and matching reagent kit,and serum FGF21 levels were measured using enzyme-linked immunosorbent assay(ELISA)and enzyme-linked immunosorbent assay(ELISA).The levels of blood lactate and FGF21 in the three groups before treatment were compared.The interaction coefficientγand OR values were used to analyze the interaction of blood lactate and FGF21 on the susceptibility of children to ME.The receiver operating characteristic(ROC)curve was used to analyze the value of blood lactate and FGF21 in the diagnosis of ME in children.The changes in blood lactate,FGF21,and Newcastle Mitochondrial Disease Assessment Scale(NMDAS)scores before and after treatment were compared between ME patients with different efficacies.Pearson correlation analysis was used to analyze the correlation between the decrease in blood lactate and FGF21 after 1 month and 3 months of treatment and the decrease in NMDAS score.Results:Compared with the control group,the levels of blood lactate and FGF21 were elevated in the ME group(t=13.901,38.082,P<0.05);compared with the muscle disease group,the levels of
