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.

目的 探讨纵隔髓外造血(EMH)的临床特点,从而为其诊断、治疗提供参考意见。方法 总结分析我科收治的1例双侧后纵隔骨髓外造血组织多发瘤样增生,并对近10年来国内相关文献报道的27例病例进行回顾性分析。结果 患者需行手术活检取得病理诊断,确诊髓外造血。结论 纵隔髓外造血瘤样增生是一种罕见特殊的良性病变, 预后良好。但因其临床表现和影像学均缺乏特异性,当临床中遇到发生在后纵隔脊柱旁的占位性病变,同时患有贫血的患者应考虑EMH 的可能性,给予经皮穿刺或者胸腔镜下活检来取得细胞学诊断,从而避免不必要的手术治疗。

Objective To probe into the clinical features of mediastinal extramedullary hematopoiesis (EMH), for providing a reference for clinical diagnosis and treatment. Methods The clinical data was studied in a case of mediastinal EMH from our department, and 27 case reports from domestic published literatures over the last decade were analyzed retrospectively. Results Of the 27 patients, 15 received surgical excision, while the other 12 underwent needle biopsy. In our patient, the diagnosis of EMH was made by mini thoracotomy and open biopsy. Conclusion Mediastinal EMH is a rare disease and its prognosis is well. Because there is no obvious specific clinical symptoms and imaging appearances, the possibility of EMH should be considered when a patient with a mediastinal tumor associated with anemia is encountered. Diagnosis can be achieved by needle biopsy or video-assisted thoracic surgery (VATS) in order to prevent unnecessary surgical procedures.
