Objective To evaluate the effect of indomethacin in the prevention of post ERCP pancreatitis (PEP) .Methods The literatures and corresponding references of randomized controlled trials (RCT ) on indomethacin in the prevention of PEP were searched from Cochrane Library (Jan 1970 to June 2013) ,Pubmed(Jan 1966 to June 2013) ,EMBASE(Jan 1966 to June 2013)and China Biology Medicine disc(Jan 1978 to June 2013) .Literature screening ,data extraction and methodological quality assessment were individually performed by two researchers .The software RevMan 5 .2 of Cochrane Collaboration was used for statistical analy‐sis .Results A total of 7 trails ,2170 patients were included in this study .Meta analysis results showed:indomethacin could effec‐tively prevent from PEP (RR=0 .45 ,95% CI:0 .33-0 .60 ,P<0 .05) and Hyperamylasemia (RR=0 .51 ,95% CI:0 .37-0 .70 ,P<0 .05) compared with placebo ,and could effectively alleviate the severity of pancreatitis after ERCP (RR=0 .43 ,95% CI:0 .23 -0 .78 ,P<0 .05) .Conclusion Indomethacin could effectively prevent from PEP and Hyperamylasemia ,and could effectively alleviate the severity of PEP .

Thyroid carcinoma is the most frequent endocrine cancer.Recently, it has been discovered that telomerase reverse transcriptase promoter mutation can prevent cell tolemeres from shortening, leading to cell immortalization and plays an important role in the tumor genesis, invasiveness and metastasis of the thyroid carcinoma.Testing of telomerase reverse transcriptase promoter mutation is of great value in diagnosis, which also can be used as a prognostic maker of thyroid carcinoma.

Three Modules and Three Stages proposed by guidelines on college English teaching that will be issued by the Ministry of Education gives direction for college English teaching.Through the investigation of the students' cognition and learning of English curriculum,combined with the teaching experiment,the new system of English curriculum,which reflects the characteristics of medical colleges and universities,has been preliminarily established,aiming at cultivating medical students' comprehensive English abilities in medical study and career development.Considering students' language abilities in different stages,college English curriculum can be designed in three modules,that is,English for general purpose (EGP),English for academic purpose (EAP) and intercultural communication,in three stages,that is,the basic stage,the improvement stage,and the development stage.The practice shows that the new curriculum system can promote the interaction,reform and development of teachers,teaching teams and Foreign Language Department.

Ovbective To evaluate whether the deleterious effect of cardiopulmonary bypass (CPB) mediated by oxygen free radicals could be prevented by controlling PaO 2 in cyanotic children. Methods Cyanotic pediatric patients undergoing cardiac surgery (n=38) were randomly allocated into 2 groups. The groups matched in respect to sex,age,body surface area and preoperative ventricular function. Group H (n=18) had CPB initiated at a FiO 2 of 0.8,group L (n=18) had CPB initiated at a FiO 2 of 0.4. SOD and MDA were determined in arterial blood sample before CPB,30 minutes after initiation of CPB and 30 minutes post CPB. Various pulmonary parameters were determined 10 minutes after intubation,30 minutes after CPB,the 2nd hours and the 6th hours in the intensive care units. Results At the 6th hours in ICU,the mean postoperative increase in peak airway pressure and P(A-a)O 2/PaO 2 in group H was significant higher than that in group L(P

Objective To find out factors affecting physicians' prescribing conduct so as to get rid of the negative effects and reduce medical costs. Methods Analyses were conducted by reviewing relevant literature published at home and abroad. Results Factors affecting physicians' prescribing conduct include: the medical security system, the hospital compensation mechanism, the requisitioning party, pharmaceuticals per se, and promotion of sales. Conclusion To get rid of the negative effects of physicians' prescribing conduct, it is necessary to rationalize the hospital compensation mechanism, strengthen the control of drug examination, approval, purchase and sale, and provide physicians with accurate pharmaceutical information.

Objective To evaluate the relationship between 5,10-Methylenetetrahydrofolate reductase(MTHFR) gene polymorphisms and colorectal cancer(CRC).Methods Studies were selected based on the criteria for inclusion.The Meta-analysis software,REVMAN 4.2,was applied for checking the heterogeneity across the studies and calculating the pooled OR.The results were evaluated by the analyses of publication bias and sensitivity.Results A total of 9 787 cases and 12 986 controls from 18 studies for C677T and a total of 4 422 cases and 5 819 controls from 9 studies for A1 298C were included.No heterogeneity among the studies was found.For codon 677,the frequencies of CC,CT and TT genotypes were 46.48%,43.81% and 9.71% in cases,and 45.03%,43.08% and 11.89% in controls,respectively.The pooled OR of TT vs.CT+CC was 0.80(95%CI 0.74～0.87).For codon 1 298,the frequencies of AA,AC and CC genotypes were 53.60%,39.39% and 7.01% in cases,and 53.31%,38.67% and 8.03% in controls,respectively.The pooled OR of CC vs.AC+AA was 0.84(95%CI 0.72～0.97).Conclusions MTHFR 677TT is at lower risk of developing CRC and 1 298CC genotypes might be associated with the decreased risk of developing CRC.

Varicose veins is the main clinical manifestations of the chronic venous insufficiency.TIPP transilluminated powered phlebectomy,a new minimally invasive surgery,received much attention while surgical techniques aimed at treating varicose vein were constantly updated.In this article,TIPP in the varicose vein surgery is reviewed from its history,operating techniques and advantages,and TIPP's future is being prospected.

ObjectiveTo explore the clinical characteristics of reversible posterior leukoencephalopathy syndrome ( RPLS ),in order to deepen the awareness of the disease.MethodsThe clinical data of 11 patients with RPLS in our hospital were retrospectively analyzed.ResultsIn the 11 cases with RPLS,there were two cases of pregnancy induced hypertension,preeclampsia(38 weeks pregnant),four eases of chronic renal insufficiency,four cases of malignant hypertension,and one case of lung cancer after chemotherapy.The main clinical presentations were headache,abnormality of visual perception,mental and behavioral abnormalities,ataxia,epileptic seizure and so on.The neuroimaging performances were extensive white matter abnormalities of the rear of the bilateral cerebral hemispheres,such as the parietal-occipital temporal lobe lesions,also involving the brain stem,cerebellum,thalamus and other parts.ConclusionThe clinical characteristics and neuroimaging performances of RPLS has certain characteristics,the majority of lesions were reversible,if the early diagnosis and treatment,the prognosis is usually good.
