目的探讨肺炎支原体(mycoplasma pneumoniae,MP)感染致小儿神经系统损伤的临床特点。方法选取2011年1月—2014年12月本院诊治为MP感染患儿3 184例,总结不同年度及不同年龄段的临床特点。计量资料比较采用t检验,计数资料比较采用χ~2检验,P<0.05为差异有统计学意义。结果 3 184例MP感染患儿中,支原体脑炎患儿有183例,平均感染率为5.75%。不同年份MP脑炎感染率(1.57%、5.06%、7.83%、8.16%)有差异,随着年份的增加发病率也在不断上升,差异有统计学意义(P<0.05)。不同年龄患儿的感染率(1.21%、6.32%、7.44%、5.86%)比较,差异有统计学意义(P<0.05);其中<3岁与3岁以上患儿的感染率比较,差异有统计学意义(P<0.05)。结论不同年度的支原体脑炎的感染率有差异,并且呈现逐年上升趋势;不同季节和性别的感染率无明显差异。
Objective To investigate the clinical features of children’s nervous system injury caused by Mycoplasma pneumoniae (MP) infection. Methods A total of 3 184 cases of MP infection were selected from January 2011 to December 2014 in our hospital, and the clinical features of different years and different ages were summarized. Measurement data were compared using t test, count data were compared using χ ~ 2 test, P <0.05 for the difference was statistically significant. Results Among the 3 184 infants with MP infection, 183 cases of mycoplasma encephalitis had an average infection rate of 5.75%. The infection rates of MP encephalitis in different years were different (1.57%, 5.06%, 7.83%, 8.16%). The incidence of MP encephalitis increased with the increase of years, the difference was statistically significant (P <0.05). The infection rates in children of different ages (1.21%, 6.32%, 7.44%, 5.86%) were statistically significant (P <0.05). The infection rates of children younger than 3 years old Statistical significance (P <0.05). Conclusions The infection rates of mycoplasma encephalitis in different years are different and show an increasing trend year by year. There is no significant difference in infection rates in different seasons and genders.
