Objective To investigate the value of endoscopic submucosal dissection (ESD) and submucosal tunneling endoscopic resection (STER) for the diagnosis and therapy of gastric ectopic pancreas.Methods A total of 86 patients who were suspicion diagnose with gastric ectopic pancreas received ESD or STER in hospital,and the therapeutic effect and safety were followed-up.Results Fifty-four gastric ectopic pancreas patients were definitely diagnosed by postoperative pathology.Of the 54 patients,43 cases were located at the gastric antrum,7 cases were located at gastric fundus and gastric corpus juncture,4 cases were located at gastric corpus.Forty-five cases received ESD,9 cases received STER,rate of completely resection was 88.9％ (48/54),6 cases had a little tissue residual after resection.One case (1.9％,1/54) happened postoperative delay-bleeding,intraoperative and postoperative perforation was not found.During 1-32 months followed up,recurrence was not found.Conclusion ESD could excise the whole lesion to offer an accurate pathology diagnose,meanwhile good for treatment,ESD is an effective and relatively safe method for gastric ectopic pancreas,STER may be a new approach for gastric ectopic pancreas.

ObjectiveTo explore the relationship between the different body mass index (BMI) ranges and all cause mortality in hemodialysis (HD) patients. MethodsEligible studies assessing the effects of BMI ranges on all-cause mortality(published from 1966 to 2012 )were searched, using hemodialysis/haemodialysis and obese/body mass index/overweight andmortality/surwival/reverse epidemiology/obesity paradox in PubMed,Embase,ScienceDirect,Wilcy,Scopus and Ovid. Inclusion criteria were that trials reported mortality in HD patients according to the traditional WHO/NIH BMI classification,and BMI levels were acceptable within 2 kg/m2.The quality of the trials was evaluated using the assessing risk of bias in studies included in Cochrane reviews.The mortality rate in HD patients was the primary endpoint of the study.ResultsWith no significant heterogeneity ( I2 =0％,P =0.45 ),a fixed-effects model was used for analysis.Four studies with a total of 81 423 patients met final inclusion criteria.Compared to individuals with non-elevated BMI levels,the elevated group (BMI ≥25 kg/m2) was associated with lower all-cause mortality ( OR 0.67,95％ CI 0.65-0.68 ). In a risk-adjusted sensitivity analysis,elevated BMI levels remained protective against mortality( adjusted HR 0.94,95％ CI 0.92-0.96 ).ConclusionsHigh BMI levels are associated with lower all-cause mortality rate in HD patients.More stable hemodynamic status,cytokine and neurohormonal alternations,and nutritional status maybe contribute to the protective effects of BMI on the mortality of HD patients.There is a need for more prospective studies to elucidate underlying mechanisms.

Objective To investigate the sensitization to HLA antigens and relationship between sensitization and allograft function after liver transplantation. Methods The panel reactive antibody (PRA) in serum was determined by using LAT ELISA kit in 15 recipients before and after liver transplantation. Results Moderate sensitization was detected in one of 15 cases before transplantation. The patient experienced one episode of mild rejection, which was reversed by treatment with Methylprednisolone. PRA in this patient maintained positive 3 months posttransplantation. The remaining 14 patients had negative PRA (

Objective To explore the pathogenesis of renal damage induced by melamine and the characteristics of kidney damage in rats.Methods Twenty Wister rats were randomly divided into one control group fed with normal pet food and one exposure group fed with animal food mixed with melamine at 25 mg(/kg?d).After 4 weeks,biochemical indexes of blood were determined,histopathological examination was performed,and kidney/body weight was measured among rats.The kidney slices were observed using light microscopy of animal anatomy.Renal tissues from affected rats were analyzed using high-performance liquid chromatography and mass spectrometry.Kidney X-ray diffraction were performed to determine the existence of crystals Results After 4 weeks of melamine exposure,the rats showed polyuria,less activity,weight loss,increasing levels of serum creatinine,urea nitrogen,triglyceride.The appearance of kidney significantly changed.The diffuse distribution of the point and the flake crystal shadow were observed in kidney slices.Histopathological examination showed the existence of a large number of crystals in renal tubular,renal tubular epithelial damage.The analysis of high-performance liquid chromatography and mass spectrometry revealed that crystals were composed of melamine and cyanuric acid.Kidney X-ray diffraction revealed that crystals could be found in kidneys of rats.Conclusion Melamine can enter the body through the digestive tract and generate partially cyanuric acid through hydrolysis.Then cyanuric acid and melamine formed cocrystals in renal tubules leading to progressive tubular blockage,renal tubular epithelial damage,tubular reabsorption dysfunction,eventually renal failure.

Objective To explore the renal toxicity induced by melamine intake single and combined with cyanuric acid.Methods Thirty-six clean weanling male Wister rats were randomly divided into 3 groups,12 in each,treated with melamine and cyanuric acid through food for 28 consecutive days,group 1 treated with melamine at 25 mg/kg,group 2 treated with melamine (25 mg/kg) plus cyanuric acid (25 mg/kg),group 3 is control,fed on normal pet food.After 4 weeks of treatment,the rats were sacrificed and blood indicators,histopathological examination of kidney were conducted.Renal tissues from the affected rats were analyzed using high-performance liquid chromatography and mass spectrometry.Kidney X-ray diffraction was performed to determine the existence of crystals.Results In group 1 and 2,polyuria,hypokinesia and weight loss (P
