Methods From July,2012 to June, 2014, we chose 128 children who had been diagnosed as bronchopneumonia by our hospital as our research subjects, and divided them into the contrast group and the observation group randomly with 64 children each. The both groups were all treated by using the methods of Antipyretic,anti-inflammatory,antitussive,antiasthmatic,anti-viral infection, treated by using erythromycin, penicillin and cefotaxime in the contrast group,treated the observation group by using Xiyanpin injection by nebulizer inhalation, of cause these two treatment were all on the basis of the conventional treatment. After treatment, we recorded the exact time of when the fever was gone, the disappearing time of pulmonary rales and their cough, the total effective rate and the time of being in hospital of the two groups. Results The time of all the observation group's symptom disappearing and being in hospital was obviously shorter than that of the contrast group after treatment. The difference between both groups was statistically significant(P<0.05). The total effective rate for the observation group was 96.88%, and it's higher than the contrast groups',which was 85.94%. The difference was statistically significant(P<0.05)too.

目的 比较肺炎支原体肺炎(MPP)、非MPP患儿和健康儿童的免疫球蛋白、补体水平,以探讨儿童MPP体液免疫指标的变化规律。方法 分别检测52例MPP、55例非MPP患儿和33例健康儿童的血清免疫球蛋白(IgG、IgA、IgM)、补体(C3、C4),并比较儿童MPP急性期和恢复早期体液免疫指标。结果 MPP组急性期血清IgM、C3、C4水平高于非MPP组急性期和健康儿童(P<0.05)。儿童MPP恢复早期IgM水平高于急性期,C4水平低于急性期(P<0.05)。结论 与非MPP和健康儿童比较,MPP患儿存在明显体液免疫功能紊乱,从急性期到恢复早期,血清IgM逐渐升高,补体C4先升高后降低,自身免疫反应可能参与了儿童MPP的发病过程。

Objective To investigate the changes of serum immunoglobulins and complement in children with mycoplasma pneumoniae pneumonia (MPP). Methods 52 children with MPP, 55 children with non-MPP and 33 healthy children were enrolled. The levels of serum immunoglobulins (IgG, IgA and IgM) and complements (C3, C4) were detected. Results Compared with the non-MPP group and healthy control, the levels of IgM, C3 and C4 in MPP group during their acute phase were significantly higher (P<0.05). And among the MPP group the levels of IgM were hisher and C4 were lower than that in the acute phase. Conclusion Immune function disturbance exists in children with MPP. From acute to recovery stage, the level of IgM increased while C4 increased firstly and then decreased. Immune injury may be involved in the pathophysiology of childhood MPP.

Objective To analyze pathogens and risk factors of VAP in a general ICU of a primary hospital. Methods Totally 112 patients(from 2013-01 to 2014-12) under mechanical ventilation over 48 h were retrospectively studied. The patients were assigned into VAP group and non-VAP group. The independent risk factors and pathogens of VAP were analyzed. Results There was significant difference between VAP group and non-VAP group in terms of emergent tracheal intubation, MV time, types of antibiotics used, the use of hormones,the use of PPI and sedative drugs for more than 7 days, regurgitation, MODS, ICU stay time. Emergent tracheal intubation:52.2％ vs 31.9％,P＝0.029;MV time:9.8±3.5day vs 7.3±2.8day,P＝0.038;types of antibiotics used > 2 kinds:52.2％ vs 26.4％,P＝0.005;the use of hormones:56.5％ vs 27.0％,P＝0.001;the use of PPI >7day:65.2％ vs 40.3％,P＝0.008;the use of sedative drugs >7day:58.7％ vs 38.9％,P＝0.035;regurgitation:50％ vs 29.2％,P＝0.022;MODS:47.8％ vs 22.2％,P＝0.004;ICU stay time:13.6±6.6day vs 10.2±5.3day,P＝0.023. The use of hormones,MV time, ICU stay time were the independent risk factors of VAP[odds ratio(OR) of multivariate logistic regression:2.481、1.234、1.075]. The main pathogens of VAP were gram-negative bacteria (82.3%). Conclusion The study shows that the use of hormones,MV time, ICU stay time are the independent risk factors of VAP; gram-negative bacteria are the main pathogens of VAP. Once VAP occurs, they can be treated with anti-gram-negative bacteria antibiotics.
