维生素A、维生素D联合抗生素序贯疗法治疗儿童肺炎支原体肺炎的效果
Efficacy of vitamin A, vitamin D combined with antibiotics sequential therapy in children with Mycoplasma pneumoniae pneumonia
目的 分析维生素A、维生素D联合抗生素序贯疗法治疗儿童肺炎支原体肺炎的效果及对心肌酶谱、单核细胞Toll样受体4 (toll like receptor 4,TLR4)/核因子-κB(nuclear factor kappa-B,NF-κB)信号通路分子表达的影响。 方法 选取收治的116例肺炎支原体肺炎患儿,随机分成对照组和观察组,各58例。对照组采用阿奇霉素序贯疗法治疗,观察组在对照组治疗的基础上联合维生素A、维生素D治疗,均连续治疗2个疗程。比较2组的临床疗效及治疗期间不良反应发生情况。检测治疗前后血清天冬氨酸氨基转移酶(aspartate aminotransferase,AST)、肌酸激酶同工酶(creatine kinase isoenzymes,CK-MB)、乳酸脱氢酶(lactate dehydrogenase,LDH)、肌酸激酶(creatine kinase,CK)水平。检测外周血Th1、Th2细胞计数及血清中TLR4、NF-κB水平。 结果 治疗后,观察组的总有效率高于对照组(P<0.05)。2组LDH、CK-MB、CK、AST、TLR4和NF-κB水平低于治疗前(P<0.05),且观察组LDH、CK-MB、CK、AST、TLR4和NF-κB水平低于对照组(P<0.05)。2组Th1细胞比例均下降(P<0.05),但2组比较差异无统计学意义。2组Th2细胞比例均显著降低,且观察组低于对照组(P<0.05);2组Th1/Th2值明显升高,且观察组高于对照组(P<0.05)。观察组不良反应发生率低于对照组(P<0.05)。 结论 维生素A、维生素D联合阿奇霉素序贯疗法治疗肺炎支原体肺炎患儿疗效明确,可降低心肌酶、TLR4、NF-κB水平,纠正Th1/Th2细胞免疫平衡,改善机体免疫状况。
Objective To analyze the curative effect of vitamin A, vitamin D combined with antibiotics sequential therapy in children with Mycoplasma pneumoniae pneumonia (MPP) and its influences on myocardial enzyme spectrum and toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathways. Methods A total of 116 children with MPP admitted to the hospital. They were randomly divided into control group (n=58) and observation group (n=58). The control group was treated with azithromycin sequential therapy, while the observation group was additionally treated with vitamin A and vitamin D.All were continuously treated for 2 courses. The clinical curative effect and occurrence of adverse reactions during treatment were compared between the 2 groups. The levels of serum aspartate aminotransferase (AST), creatine kinase MB (CK-MB), lactate dehydrogenase (LDH) and creatine kinase (CK) were detected by full-automatic biochemical analyzer before and after treatment. The counts of peripheral blood Th1 and Th2 were detected by flow cytometry. The levels of serum TLR4 and NF-κB were detected by enzyme-linked immunosorbent assay. Results The total response rate in observation group was higher than that in control group (P<0.05). After treatment,the levels of LDH, CK-MB, CK, AST, TLR4 and NF-κB in both groups were decreased (P<0.05), which were lower in observation group than in control group (P<0.05). After treatment, the proportion of Th1 in both groups was decreased (P<0.05), but there was no significant difference between the 2 groups (P>0.05). After treatment, the proportion of Th2 in both groups was significantly decreased, which was lower in observation group than in control group (P<0.05). After treatment, the Th1/Th2 ratio in both groups was significantly increased,which was higher in observation group than in control group (P<0.05). The incidence of adverse reactions in observation group was lower than that in control group (P<0.05). Conclusion The curative effect of vitamin A, vitamin D combined with azithromycin sequential therapy is significant in children with MPP, which can reduce the levels of myocardial enzymes, TLR4 and NF-κB, correct the immune balance of Th1/Th2 and improve immune status.
