摘要:目的 探討血清中白介素-8(IL-8)、白介素-10(IL-10)和降鈣素原(PCT)在小兒肺炎支原體肺炎發(fā)病中的臨床價(jià)值。方法 用ELISA法和化學(xué)發(fā)光法檢測(cè)62例肺炎支原體肺炎患兒治療前后及50例同期幼兒園和小學(xué)生健康體檢者血清中IL-8、IL-10和PCT水平,結(jié)合臨床相關(guān)檢查資料,對(duì)檢測(cè)結(jié)果采用SPSS18.0統(tǒng)計(jì)軟件進(jìn)行統(tǒng)計(jì)學(xué)分析,各組實(shí)驗(yàn)數(shù)據(jù)以均數(shù)±標(biāo)準(zhǔn)差(x±s)表示,各實(shí)驗(yàn)組間比較計(jì)量資料的t檢驗(yàn),P<0.05為有統(tǒng)計(jì)學(xué)意義。結(jié)果 MPP組治療前:IL-8(16.38±9.63 pg/ml)、IL-10(13.59±8.41 pg/ml)、PCT(0.68±0.52 mg/L)與對(duì)照組IL-8(4.66±3.92 pg/ml)、IL-10(5.67±3.03 pg/ml)、PCT(0.29±0.16 mg/L)濃度比較有顯著性差異(P<0.05);MPP組治療6~8d后IL-8(5.15±4.49 pg/ml)、IL-10(6.42±5.06 pg/ml)、PCT(0.31±0.18 mg/L)濃度較治療前均有明顯下降,有顯著性差異(P<0.05),與健康對(duì)照組比較,兩者差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。結(jié)論 MPP患兒入院治療前、治療后血清IL-8、IL-l0,PCT含量的變化對(duì)疾病的進(jìn)展和療效有一定指導(dǎo)意義,提示IL-8、IL-10和PCT在MPP發(fā)病機(jī)制中起重要作用。

Abstract:Objective To explore the clinical application of serum IL-8、IL-10 and PCT in children with Mycoplasma Pneumonia(MPP).Methods The levels of serum IL-8、IL-10 and PCT of 62 cases of children with MPP、50 health students as control group were detected by ELISA or chemiluminescence assay at the same time.The clinical relative factors and experimental data were statistically analyzed using SPSS18.0 statistical software,each set of experimental data expressed as mean±standard deviation,in each experimental group were analyzed by using t-test,P<0.05 was considered statistically significant.Results The levels of serum IL-8、IL-10 and PCT of MPP children(IL-8(16.38±9.63 pg/ml)、IL-10(13.59±8.41 pg/ml)、PCT(0.68±0.52 mg/L))were remarkably higher than those in control group(IL-8(4.66±3.92 pg/ml)、IL-10(5.67±3.03 pg/ml)、PCT(0.29±0.16 mg/L)),P<0.01 After 6-8 days treatment,the levels of serum IL-8、IL-10 and PCT of MPP children were remarkably decreased and have no significant difference with those in control group.Conclusion The change of serum IL-8、IL-10 and PCT in children with MPP during the treatment indicates that serum IL-8、IL-10 and PCT play an important effect in the pathogenesis of MPP.

近年來肺炎支原體肺炎(Mycoplasma pneumonia,MPP)發(fā)病率呈逐年增高趨勢(shì),發(fā)病后可引起多器官損害,對(duì)小兒身體健康影響極大,甚至威脅生命或死亡。肺炎支原體是介于病毒與細(xì)菌之間的一種病原微生物,是引起小兒肺炎的常見病原體之一。急性期存在某些細(xì)胞因子濃度的異常,導(dǎo)致細(xì)胞免疫功能低下和紊亂[1,2]。本研究通過檢測(cè)MPP患兒入院治療前、治療后血清細(xì)胞因子8(IL-8)、細(xì)胞因子10(IL-10)和降鈣素原(PCT)的水平與同期健康兒童對(duì)比,為臨床更好治療MPP患兒提供理論依據(jù),現(xiàn)報(bào)告如下:
