摘　　要：目的评价楂曲消风散治疗儿童特应性皮炎(AD)湿热蕴结证的临床疗效及其对皮肤菌群的调控作用。方法采用随机对照试验设计,将90例患儿随机分为治疗组和对照组各45例。治疗组内服楂曲消风散,对照组内服盐酸西替利嗪滴剂,疗程均为4周。分别记录治疗前及治疗2、4周两组患儿特应性皮炎积分指数(SCORAD)评分、瘙痒视觉模拟量表(VAS)评分、儿童皮肤病生活质量指数问卷(CDLQI)评分、中医证候(心烦、口渴、纳呆、小便短赤、大便干或黏)评分。分别于两组中各随机选择25例患儿,在治疗前后进行皮损处皮肤取样,提取皮肤样本DNA进行16S rRNA基因扩增子测序,检测皮肤菌群水平,对菌种分布、菌群多样性及组间差异进行比较。结果治疗组与对照组各脱落5例,最终两组各40例纳入分析。与治疗前比较,两组治疗2、4周SCORAD评分、VAS评分、CDLQI评分均较治疗前降低,且治疗4周改善程度均优于治疗2周(P<0.01)。治疗4周,治疗组SCORAD评分、VAS评分、CDLQI评分显著低于对照组(P<0.01)。与治疗前比较,治疗组心烦、口渴、纳呆、小便短赤、大便干或黏评分均降低(P<0.05);对照组口渴、纳呆、小便短赤评分均降低(P<0.05)。治疗后治疗组心烦、纳呆、小便短赤、大便干或黏评分低于对照组(P<0.05)。两组治疗前后菌种相对丰度比较,对照组缓症链球菌、大肠杆菌、金黄色葡萄球菌、溶血孪生球菌相对丰度下调,对照组缓症链球菌相对丰度下调(P<0.05)。治疗后治疗组金黄色葡萄球菌、缓症链球菌、大肠杆菌、溶血孪生球菌相对丰度低于对照组,且差异有统计学意义(P<0.05)。Alpha多样性分析发现,与治疗前比较,治疗组治疗后Chaol指数、Shannon指数均升高(P<0.05),对照组治疗前后Chaol指数、Shannon指数差异无统计学意义(P>0.05),且治疗后治疗组Chaol指数、Shannon指数均高于对照组(P<0.05)。Beta多样性分析Objective To assess the clinical efficacy and regulation of skin microbiota in children with atopic dermatitis and damp-heat accumulation syndrome treated by Zhaqu Xiaofeng Powder(楂曲消风散,ZXP).Methods Ninety children were randomized into a treatment group and a control group,each with 45 children.The treatment group received ZXP orally,while the control group received levocetirizine hydrochloride syrup,both for 4 weeks.The atopic dermatitis severity index(SCORAD)score,visual analog scale(VAS)score for itching,children dermatology life quality index(CDLQI)score,and traditional Chinese medicine syndrome score were assessed before and after 2-and 4-week treatment.Simultaneously,adhering to the principles of sample size in microbial sequencing,25 children were randomly selected from each group(total 50 children);skin samples were collected before and after treatment,and skin specimen DNA was extracted for 16S rRNA gene amplifier sequencing;the skin microbiota levels were detected,and the distribution of bacteria,diversity of flora,and differences between groups were compared.Results There were five drop-outs in each group,and 40 cases in each group were included in final analysis.After 2-and 4-week treat⁃ment,both groups showed a significant reduction in SCORAD scores,VAS scores,and CDLQI scores,and more re⁃ductions were shown after 4-week treatment than 2-week treatment(P<0.01).The SCORAD score,VAS score,and CDLQI score of the treatment group were significantly lower than those in the control group after 4-week treat⁃ment(P<0.01).The scores of upset,thirsty,poor appetite,short red urine,and dry stool were reduced in the treatment group(P<0.05),while the scores of thirsty,poor appetite,short and red urine decreased after treatment(P<0.05).After 4 weeks of treatment,among the differential genera with abundances>0.5%in the treatment group,The cumulative relative abundances of Staphylococcus aureus,Streptococcus_mitis,Escherichia coli and Gemella_haemolysans in the treatment group were downregulated after
