[摘要] 目的 研究并探讨肺炎支原体感染与小儿支气管哮喘发作的相关性。 方法 于2015年1月―2017年1月期间,方便选取该院收治的70例支气管哮喘急性发作期患儿和70例上呼吸道感染患儿设置为观察组、对照组,所有患儿均接受血清肺炎支原体抗体(MP-IgM)检测,统计两组MP-IgM阳性检出情况,再将观察组分为MP-IgM阳性组、阴性组,对其呼出气一氧化氮(FeNO)浓度、外周血嗜酸性粒细胞比例(EO)、血清特异性IgE进行检测。 结果 观察组的MP-IgM阳性率为45.71%,对照组为15.71%,经比较,观察组的MP-IgM阳性率高于对照组(P /6/view-10742970.htm

[Abstract] Objective This paper tries to study and explore the correlation between mycoplasma pneumoniae infection and bronchial asthma in children. Methods From January 2015 to January 2017, 70 cases of children with acute bronchial asthma and 70 cases of children with upper respiratory tract infection who admitted in this hospital were convenient selected and regarded as the observation group and the control group. All the children were tested for serum mycoplasma pneumoniae antibody (MP-IgM), the positive rate of MP-IgM in two groups was counted, and the observation group was divided into MP-IgM positive group and negative group, the levels of exhaled nitric oxide (FeNO), peripheral blood eosinophils (EO) and serum specific IgE were examined. Results The positive rate of MP-IgM in the observation group was 45.71%, and that in the control group was 15.71%. The positive rate of MP-IgM in the observation group was higher than that in the control group (P统计学意义(P>0.05),研究具有可比性,且患儿家长均签署知情同意书。 1.2 方法
所有患儿均接受血清肺炎支原体抗体(MP-IgM)检测,采集空腹静脉血液,离心处理10 min,离心速度为3 300 r/min,取血清,采用肺炎支原体抗体检测试剂盒测定,检测方法为免疫凝集法,如MP-IgM滴度达到1:80即阳性[3]。
根据支气管哮喘患儿的血清MP-IgM检测结果,将观察组患儿分为阳性组、阴性组,对患儿的FeNO浓度、外周血嗜酸性粒细胞比例(EO)、血清IgE水平进行检测,其中, FeNO于患儿静息状态时采用FeNO分析仪测定,呼气后含住滤嘴,深吸一口气,再缓慢呼出;外周血嗜酸性粒细胞比例(EO)采用全自动血细胞分析仪测定;血清IgE采用Pharmacia UNICAP系统检测,检测方法为荧光酶联免疫法。
1.3 观察指标
比较观察组与对照组患儿的血清MP-IgM阳性检出情况;比较血清MP-IgM阳性组与阴性组患儿的FeNO浓度、EO%、血清IgE水平;采用皮尔逊相关系数分析法,对肺炎支原体感染与小儿支气管哮喘急性发作、FeNO、EO%、血清IgE的相关性进行明确。
1.4 统计方法
数据应用SPSS 19.0统计学软件分析,计数资料行χ2检验,计量资料行t检验,并分别用[n(%)]、(x±s)表示,P参考文献]
