Clinical characteristics of pediatric patients with H1N1 influenza A virus-associated pneumonia / 中华传染病杂志

Objective To understand the clinical characteristics of pediatric patients who developed H1N1 influenza A virus-associated pneumonia during the outbreak of H1N1 influenza A in Shanghai. MethodsA dcscriptivc study was done to analyze the clinical and epidemiologic characteristics of 30 hospitalized children who developed complicated pneumonia caused by H1N1 influenza A virus infection in 2009 in Shanghai. The comparison of medians was done using rank sum test and comparison of rates was done using exact chi-square test. Results Among thirty pediatric patients with H1N1 influenza A virus-associated pneumonia, the median age was 5.9 years old, five cases (16.7 %) had pre-existing medical conditions. Twenty cases (66.7 % ) had been exposed to the classmates or family membcrs with fever. All cases had fever and cough. Eleven cases (36.7 %00 ) had tachypnca and ten (33.3%) had wheeze. Eleven cases (36.7%) showed white blood cell (WBC)＜4.0 × 109/L and 2 (6. 7%) had thrombocytopenia. All patients had bilateral or unilatcral patchy infiltrates in the lung indicated by chest X-ray and four (13. 3%) had extensive infiltrates with the evidence of pulmonary edema. One (3. 3%) critically ill child with pneumonia, chest computed tomography scan revealed lung fibrosis 3 months and 9 months after illness onset. Three(10. 0%) cases had pneumomediastinum and subcutaneous emphysema. Six cases (20. 0%) were complicated with acute respiratory failure, three (10. 0%) with acute asthmatic attack and one (3. 3%) with encephalitis. All patients were treated with oseltamivir plus antibiotics and four required mechanical ventilation. All patients survived. The median duration of fever in group with oseltamivir given within 2 days of fever onset was statistically shorter than that in group with oseltamivir given 2 days after fever onset (2 days vs 5 days, Z= -8. 015, P<0. 01). Conclusions Both pre-school age and schoolage children may develop complicated severe respiratory diseases after H1N1 influenza A virus infection. Early initiation of oseltamivir may shorten the duration of fever and reduce the occurrence of severe complications.

Correlation and expression of PTEN and vascular endothelial growth factor in human esophageal carcino-ma / 中国综合临床

Objective To investigate the expression of PTEN and vascular endothelial growth factor (VEGF) in esophageal carcinoma and the relationship between their expression.Methods The expression of PTEN and VEGF were detected using immunohistochemical S-P method.Results Among 80 cases of esophageal carcino- ma,31 showed positive staining of PTEN (38.75%),while all 20 case of normal mucosa showed positiva staimng of PTEN.The expression level of PTEN in highly differentiated squamous carcinoma was higher than that low differ- entiated squamous carcinoma.Also,the expression of PTEN was significantly correlated with lymph node metastasis (r=0.61,P<0.01)and differentiation(r=0.57.P<0.05).In 80 cases of esophageal carcinoma,57(70.13%) were of positive staining of VEGF,while in 20 of normal esophageal mucosa,only 3 showed positive staining of VEGF.The expression of VEGF was markedly correlated with infiltrative deepness(r=0.49,P<0.05)and lymph node metastasis(r=0.55,P<0.05)and differentiation(r=0.48,P<0.05).Conclusion Combined detection of PTEN and VEGF maybe helpful to evaluate prognosis and infiltrative capability of esophageal carcinoma,with sig- nificant importance to the prediction of the prognosis of esophageal carcinoam.

The effect of redix salviae miltiorrhizae on lipidperoxidation in acute ischemic myocardium / 中国病理生理杂志

The level of lipid peroxides of myocardium both in ischemic and in nonischemic zone was determined by thiobarbituric acid flourophotometry. And the relationship between the level of lipid peroxides in ischemic myocardium and ST-segment elevation was studied using the experimental animal model of acute myocardial ischemia by ligating the branch of left coronary artery. In the present experiment, the protective effects of Radix Salviae Miltiorrhizae(RSM) on ischemic myocardium was studied by observing lipid peroxides and ECG. The results showed that the value of lipid peroxides in the ischemic zone of ischemic group was 2.4 times more than that in the control group (P
