Objective To study the clinical characteristics of severe pneumonia in children , to explore the significance of neutrophil elastase detection. Methods Patients were divided to severe pneumonia group and non-severe pneumonia group Fever, cough, lung wet rale duration and image changes were statistically analyzed. The percentage of abnormal lymphocyte in peripheral blood was counted by Wright's dyeing method. The neutrophil elastase expression in peripheral blood was determinated by enzyme-linked immunosorbent analysis. Results In severe pneumonia group,atelectasis occurred in 5 cases,8 cases complicated with heart failure, 8 cases complicated with respiratory failure and 4 cases were complicated with toxic encephalopathy. In severe pneumonia group , fever time was 13.5±5.1 days, cough time was 15.1±3.2 days, the time of lung wet rale duration was 12.2±2.3 days, which were significantly longer than that of non-severe pneumonia group (t = 2.346,2.457,2.346,P < 0.05);In severe pneumonia group , pathogens included streptococcus pneumoniae , respiratory syncytial virus and adenovirus , etc.In severe pneumonia group,the percentage of abnormal lymphocyte in peripheral blood smear increased with virus infection (8.1±1.2)%. In 12 cases of severe pneumonia,the expressions of neutrophil elastase were 127.6± 12.5 ng/ml, more than that of non-severe pneumonia group (75.4 ± 6.4 ng/ml,t=3.047, P<0.05). Conclusion Severe pneumonia is a serious diseases impacting children health. Detection of neutrophil elastase shows a markedly clinical value to judge the severity of pneumonia.

Objective To investigate the effect of different excipients of propofol on blood lipids and liver function during orthotopic liver transplantation. Methods Forty ASA Ⅲ- Ⅳ patients aged 40-64 yr weighing 50-75 kg undergoing orthotopic liver transplantation were randomly divided into 2 groups ( n = 20 each): propofol medium-chain triglycerides/long-chain triglycerides (MCT/LCT) group (group M) and propofol LCT group (group L). Anesthesia was induced with penehyclidine 1 mg, midazolam 0.04-0.06 mg/kg, sufentanil 0.6-0.8 μg/kg and propofol 1.5-2.0 mg/kg. Tracheal intubation was facilitated with vecuronium 0.10-0.15 mg/kg. The patients were mechanically ventilated. Anesthesia was maintained with 1%-2% isoflurane, continuous infusion of propofol blood samples were collected after admission into the operation room (T1), before skin incision (T2), at the end of pre-anhepatic phase (T3), at the end of anhepatic phase (T4) and 30 and 240 min of neohepatic phase (T5, T6 )for determination of plasma concentrations of triglyceride (TG), total cholesterol (CH), high-density-lipoproteincholesterol (HDL-C), low density-lipoprotein-cholesterol (LDL-C), and activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). The changes in parameters from baseline values were calculated. Results Compared with group L, △TG was significant1y decreased at T4-6 in group M ( P < 0.05 ) . There was no significant difference in △CH, △HDL-C, △LDL-C, △AST and △ALT,plasma concentrations of TG,CH, HDL-C and LDL-C,and activities of AST and ALT between the two groups ( P > 0.05). Conclusion The effect of the two formulations of propofol on liver function is comparable. Propofol MCT/LCT exerts less effect on blood lipids during liver transplantation and is more suitable for this type of surgery.
