[摘 要] 目的:观察生长激素缺乏症(growth hormone deficiency,GHD)儿童在应用聚乙二醇重组人生长激素(polyethylene
glycol⁃conjugated⁃recombinant human growth hormone,PEG⁃rhGH)治疗前后淋巴细胞亚群、免疫球蛋白、辅助T细胞(Th1/Th2)细
胞因子水平等免疫指标的变化,探讨PEG⁃rhGH对GHD儿童免疫功能的影响。方法:选取2022年5月—2023年6月就诊于淮安
市第一人民医院及洪泽区人民医院儿科的55例GHD患儿为研究对象,依据患者意愿将其分为对照组(n=25)和PEG⁃rhGH组
(n=30),对照组予以运动、饮食及睡眠指导,PEG⁃rhG组在此基础上给予PEG⁃rhGH治疗,检测治疗前和治疗3个月时两组患儿身

[Abstract] Objective:The study aimed to investigate the impact of polyethylene glycol ⁃ conjugated recombinant human growth
hormone(PEG⁃rhGH)treatment on immune function in children with growth hormone deficiency(GHD),by analyzing changes in
lymphocyte subsets,immunoglobulin levels,and T helper cell(Th1/Th2)cytokines before and after treatment. Methods:Fifty⁃five
children diagnosed with GHD were enrolled as study participants from May 2022 to June 2023 at the Department of Pediatrics of Huai’
an First People’s Hospital and Hongze District People’s Hospital. According to the preferences of the participants,they were allocated
into a control group(n=25)and a PEG⁃rhGH group(n=30). The control group received guidance on exercise,diet,and sleep,while the
PEG⁃rhGH group received PEG⁃rhGH treatment in addition to these interventions. Measurements of height,bone age,BMI,insulin⁃like
growth factor⁃1(IGF⁃1),lymphocyte subsets,Th1/Th2 cytokines,and immunoglobulin(Ig)levels were conducted at baseline and 3
months post⁃treatment. The changes in various parameters before and after the intervention were compared. Results:Before treatment,
