【摘要】 目的:分析氨溴索治療新生兒肺炎對患兒炎性介質(zhì)因子及肺血流指標的影響,旨在為臨床診斷及治療新生兒肺炎的方法提供科學參考。方法:回顧選取本院接診的新生兒肺炎病例62例,依據(jù)用藥方案的不同分為兩組,常規(guī)治療組30例,實施常規(guī)對癥治療;聯(lián)合治療組32例,基于常規(guī)治療組,加用氨溴索治療。比較兩組治療2周后炎癥介質(zhì)指標hs-CRP、TNF-α,IFN-γ、IL-2、IL-6、IL-10與肺血流動力學指標PVR、mPAP、PAWP的表達變化。結果:治療后,聯(lián)合治療組炎性應激因子hs-CRP(2.26±0.81)pg/mL、IFN-γ(24.26±4.19)pg/mL表達均較常規(guī)治療組明顯下降,而TNF-α(37.49±6.22)pg/mL表達較常規(guī)治療組明顯上升,兩組比較差異均有統(tǒng)計學意義(P<0.05)。治療后,聯(lián)合治療組其他炎性因子IL-2(3.21±0.83)pg/mL、IL-6(79.16±11.59)pg/mL、IL-10(4.46±2.28)pg/mL表達均比常規(guī)治療組顯著下降,兩組比較差異均有統(tǒng)計學意義(P<0.05)。治療后,聯(lián)合治療組肺血流動力學指標mPAP(23.21±10.83) mm Hg、PAWP(8.82±2.84) mm Hg與PVR(1.46±0.76) mm Hg表達水平顯著低于常規(guī)治療組,兩組比較差異均有統(tǒng)計學意義(P<0.05)。結論:鹽酸氨溴索注射液應用于新生兒肺炎中可顯著改善患兒肺血流動力學和血清炎性因子的表達水平,有較好的治療意義。

【Abstract】 Objective:To analyze the effects of Ambroxol on neonatal pneumonia in children with inflammatory mediators and pulmonary blood flow,to provide scientific reference for clinical diagnosis and treatment of neonatal pneumonia.Method:62 cases of neonatal pneumonia admitted in our hospital were retrospectively selected.According to the different treatment regimen,they were divided into two groups.30 patients were in the conventional treatment group, they were treated with conventional symptomatic therapy.The combined treatment group of 32 cases,they were taken with Ambroxol treatment based on conventional treatment.The changes of the expression levels of inflammatory mediators hs-CRP,TNF-α,IFN-γ,IL-2,IL-6,IL-10 and pulmonary hemodynamic parameters PVR, mPAP, PAWP of two groups were compared after treatment 2 weeks.Result:After treatment,the expression of inflammatory factors hs-CRP (2.26 ± 0.81) pg/mL and IFN-γ (24.26±4.19) pg/mL in combination treatment group were significantly lower than those in conventional treatment group, while the expression of TNF-α (37.49±6.22) pg/mL in combination treatment group was significantly higher than that of the conventional treatment group,the differences were statistically significant(P<0.05).After treatment,the expression of IL-2 (3.21±0.83) pg/mL,IL-6 (79.16±11.59) pg/mL,IL-10 (4.46±2.28)pg/mL in the combination treatment group decreased significantly than those of conventional treatment group, the differences were statistically significant(P<0.05).After treatment,the pulmonary hemodynamic parameters of mPAP (23.21±10.83) mm Hg,PAWP (8.82±2.84) mm Hg and PVR (1.46±0.76) mm Hg expression levels in the combined treatment group were significantly lower than those in the conventional treatment group,the differences were statistically significant(P<0.05).Conclusion:Ambroxol hydrochloride injection can significantly improve the pulmonary hemodynamics and the level of serum inflammatory factors in neonates with pneumonia,it has a good therapeutic significance.

由于嬰幼兒清除外界物質(zhì)功能差,易誘發(fā)肺炎[1-3]。有研究表明,新生兒肺炎易造成心力衰竭、敗血癥等后果[4]。有研究指出,氨溴索對呼吸窘迫綜合癥等效果顯著[5-7]。也有專家表示,氨溴索可改善新生兒肺炎肝功能,本文研究氨溴索對新生兒肺炎改善情況[8],現(xiàn)報道如下。
1 資料與方法
1.1 一般資料 選取62例本院2013-2015年接診的新生兒肺炎,(1)納入標準:①均達到嬰幼兒重癥肺炎診斷標準;②患兒信息完整,按時按劑量用藥[9-10]。(2)排除標準:①合并其他呼吸道疾病;②存在藥物過敏[11]。將患兒分為兩組,常規(guī)治療組30例,單純常規(guī)治療,男女嬰比19∶11,出生(11.26±2.15)d;聯(lián)合治療組32例,給予常規(guī)治療加用氨溴索,男女嬰比17∶15,出生(10.94±2.07)d。兩組的一般資料比較,差異均無統(tǒng)計學意義(P>0.05),具有可比性。
1.2 方法 常規(guī)治療組實施吸痰和給氧處理,聯(lián)合治療組基于常規(guī)治療組,加用鹽酸氨溴索注射液7.5 mg/(kg·d)(天津藥物研究院藥業(yè)有限公司,國藥準字H20051604,批號:121129、140516),分兩次使用。
1.3 觀察指標 治療前后比較腫瘤壞死因子-α(tumor necrosis factor-α,TNF-α)、干擾素-γ(interferon-γ,IFN-γ)、白細胞介素-2(interleukin-2,IL-2)、白細胞介素-6(interleukin-6,IL-6)和白細胞介素-10(interleukin-10,IL-10),檢測超敏C反應蛋白(hypersensitive C-reactive protein,hs-CRP)、平均肺動脈壓(Mean pulmonary artery pressure,mPAP)、肺動脈楔壓(pulmonary artery wedge pressure,PAWP)與肺血管阻力(Pulmonary Vascular Resistance,PVR)。
1.4 統(tǒng)計學處理 使用SPSS 21.0統(tǒng)計軟件進行分析,計量資料采用(x±s)表示,比較采用t檢驗,計數(shù)資料采用 字2檢驗,以P<0.05為差異有統(tǒng)計學意義。
2 結果
2.1 兩組患兒的應激因子水平比較 治療前,兩組TNF-α、IFN-γ、hs-CRP水平比較差異均無統(tǒng)計學意義(P>0.05);治療后,兩組應激因子水平較治前均顯著改善(P<0.05),且聯(lián)合治療組hs-CRP、IFN-γ水平顯著低于常規(guī)治療組,TNF-α水平顯著高于常規(guī)治療組 (P<0.05),見表1。
2.2 兩組患兒的其他炎性因子比較 治療前,兩組IL-2、IL-6、IL-10水平比較差異均無統(tǒng)計學意義(P>0.05);治療后,兩組患兒其他炎性因子水平較治療前均明顯改善(P<0.05),且聯(lián)合治療組IL-2、IL-6、IL-10顯著低于常規(guī)治療組(P<0.05),見表2。
2.3 兩組患兒的肺血流指標比較 治療前,兩組mPAP、PAWP與PVR比較差異均無統(tǒng)計學意義(P>0.05);治療后,均明顯改善(P<0.05),且聯(lián)合治療組mPAP、PAWP與PVR比常規(guī)治療組下降明顯(P<0.05),見表3。
3 討論
新生兒肺炎若治療不及時可引起多器官衰竭[12-14],常規(guī)治療易傷害呼吸系統(tǒng),引發(fā)感染[15-17]。鹽酸氨溴索為快速黏液溶解劑,已有醫(yī)療中心用于新生兒肺炎,但報道較少[18-20]。本研究發(fā)現(xiàn),聯(lián)合治療組炎癥介質(zhì)hs-CRP、TNF-α、IFN-γ、IL-2、IL-6、IL-10和肺血流動力學指標PVR、mPAP與PAWP均改善良好(P<0.05),這可能與氨溴索作用于肺部組織時有良好的特異性和抗氧化作用,促進TNF-α生成,減少炎癥介質(zhì)的釋放,維護呼吸系統(tǒng)自凈有關。綜上所述,氨溴索可顯著改善新生兒肺炎炎癥介質(zhì)水平,對患兒肺血流動力學有積極影響。
