Objective To explore the normal range of serum glycated albumin (GA) during the second trimester in non-gestational diabetes mellitus (GDM) population and the value of serum GA in the blood glucose monitoring during pregnancy.Methods The GA was measured in 101 healthy gravida during the second trimester and 80 gravida with GDM and diabetes mellitus who were in treatment at Peking University First Hospital between August 2011 and December 2011,in order to analyze the normal range of GA and the relationship between GA and the level of blood glucose.Results (1) The normal range of GA during the second trimester was 10.9％-15.3％,which was negatively correlated with body mass index (P＜0.01).(2) Significant correlations were observed between GA and the level of hemoglobin A1c (HbA1c),preprandial,postprandial and mean plasma glucose in gravida with GDM and diabetes mellitus (r:0.361,0.252,0.338,0.310 ; all P ＜ 0.05).(3) When the level of GA was 13.97％,the sensitivity and specificity index for glucose control were 78.0％ and 74.4％.Conclusions GA could evaluate the severity of disease in gravida with GDM and diabetes mellitus.10.9％-15.3％ could be suggested as normal range of GA for the gravida at the second trimester.

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 Explore the risk factors and prevention of HAP after surgical excision of Esophageal carcinoma in elderly Patients.Methods Two hundred and eight elderly patients with HAP after Surgical excision of Esophageal carcinoma from 2009 to 2012 were analyzed.Logistic regression analysis was used to find the related risk factors.Results The incidence of HAP was 25.9％.In several factors Logistic regression analysis,smoking,low lung function,postoperative non-epidural analgesia,injure of recurrent laryngeal nerve and fistula of anastomotic were the risk factors.Conclusions The preoperative evaluation,Intensive monitoring during the postoperative period and reducing the complication after operation can decrease the incidence of HAP.

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.
