Methods Literatures in CBM, CNKI, VIP, WanFang databases were searched from the time of establishment of these databases till July 2010. Randomized controlled trials (RCT) of budesonide versus dexamethasone for the treatment of acute laryngitis in children were gathered, and quality was evaluated and meta-analysis was carried out. Results Eleven RCTs were identified, and meta-analysis indicated that there were significant differences between the two groups in the disappearing time of hoarseness, barking cough, dyspnea and laryngeal stridor. The MD values and their 95% CI were respectively -0.88 (-1.10, -0.65), -1.43 (-2.01, -0.84), -0.48 (-0.63, -0.32), and -0.59 (-0.78, -0.41). Conclusion Based on current evidence in China, budesonide is better than dexamethasone for the improvement of acute laryngitis in children.

Objective To evaluate the effects of emergency coronary artery bypass grafting (ECABG) in the treatment of emergent patients, and to summarize our experience. Methods We retrospectively analyzed the clinical data of 160 patients who underwent coronary artery bypass grafting (CABG) in Nanjing General Hospital of Nanjing Command from January 2010 through December 2013. The patients were divided into an ECABG group (operation underwent on the day diagnosed, n=27, 22 males and 5 females, at age of 70.2±10.2 years) and a conventional group (CABG operation underwent on 5 days after diagnosed, n=133, 104 males and 29 females, at age of 66.3±8.9 years). Results Statistical differences were found between the ECABG group and the conventional group in EuroSCORE (5.8±3.2 versus 3.4±2.1, P=0.001), acute myocardial infarction (33.3% vs. 11.3%, P=0.007), rate of application of IABP (29.6% versus 12.0%, P=0.034), pericardium and mediastinal tube drainage (533.4±132.8 ml versus 414.8±124.3 ml, P=0.018). There was no statistical difference in continuous renal replacement therapy (P=0.677), postoperative sternal wound complication (P=1.000), the length of hospital stay (P=0.589), or 30-day-mortality (P=0.198) between the two groups. We followed up 24 patients(88.89%) for 3-36 months in the ECABG group. One patient occurred angina symptoms at the end of 1 year follow-up. The symptoms disappeared after treatment. The other patients had no symptoms of angina pectoris and myocardial ischemia. Conclusion ECABG as a lifesaving therapy is an effective procedure in the treatment of severe and acute patients. Sufficient preoperative assessment, good myocardial protection, full revascularization, and comprehensive treatment plays an important role in the success of ECABG.
Many meta-analysis studies evaluate rates as parameter to assess the overall estimate of effects. However, none of these studies address systematic approaches for the meta-analysis of rates. This paper outlines the conditions, analysis and software operation procedures for the meta-analysis of rates. It also compares different operation procedures of three types of commonly-used R software (Comprehensive Meta-Analysis, Stata and MetaAnalyst) through real application examples. The biggest challenge for the meta-analysis of rates is to determine whether rates can be pooled, and how to evaluate heterogeneity between studies' outcomes needs further discussion.
Purpose To identify matrix metalloproteinase (MMP) in human vitreous samples of diabetic vitreoretinopathy (DR) and other ocular diseases (non-DR) and to probe the related factors of MMP expression． Methods Thirty-one diabetic and 17 non-diabetic vitreous samples (nine macular hole and eight epiretinal membrane patients) were examined． Samples were concentrated and subjected to substrate zymography to conduct a quantitative analysis of MMP-2,9 activity． The technology of Western blotting against anti-human MMP-2,9 was performed to identify MMP in vitreous samples． Results Vitreous samples both from DR patients and from non-DR patients showed a single band at the position of 72 kDa, correspondin g to MMP-2． Quantitative analysis revealed that diabetic vitreous showed higher MMP-2 activity than non-DR, although the difference was not significant.45.2% of DR patients showed MMP-9, but no expression in non-DR．Among DR samples, the positive ratio of MMP-9 in partial posterior vitreous detachment (PVD)(66．7%) was significantly higher than that of complete PVD (15．4%)． Western blotting study confirmed the expression of MMP-2 and MMP-9． Conclusion There is no obvious difference of MMP-2 activity between DR and non-DR． MMP-9 may be involved in the pathogenesis of diabetic vitreor etinopathy and the deterioration of proliferative change． (Chin J Ocul Fundus Dis, 2001,17:195-197
ObjectiveTo investigate the expression of gasdermin (GSDM) gene family in primary liver cancer and its clinical significance. MethodsThe Gene Expression Profile Data Dynamic Analysis (GEPIA2) database was used to analyze the expression levels of GSDM gene family in primary liver cancer and normal tissues, and survival analysis was performed to explore its relationship with prognosis; GEPIA2 database was used to explore the relationship between GSDM gene family and TNM staging of patients with primary liver cancer. We used GeneMANIA database to predict genes that may interact with GSDM gene family, and used Metascape website for functional enrichment analysis. Finally, we used TIMER database to explore the relationship of expression of GSDM gene family and immune cell infiltration in the tumor microenvironment of primary liver cancer. ResultsCompared with normal liver tissues, GSDMA, GSDMC, GSDMD, and GSDME were highly expressed in primary liver cancer (P<0.050), and GSDMB and DFNB59 were low expressed (P<0.050); results of univariate Cox proportional hazard regression model showed that the differential expressions of GSDMD, GSDME, and DFNB59 were related to the overall survival of patients (P<0.050), and the results of the multivariate Cox proportional hazard regression model showed that GSDME could be used as an independent predictor of the prognosis of liver cancer patients (P<0.050). With the increase of TNM staging in patients with liver cancer, the expressions of GSDMA and GSDMC also gradually increased (P<0.050). Further enrichment analysis showed that the GSDM gene family was involved in pyrolysis and various immune-related biological processes. ConclusionThe GSDM gene is differentially expressed in primary liver cancer, participates in immune-related biological processes, and its expression is related to clinicopathological staging and patients’ prognosis.
