ObjectiveTo evaluate the efficacy of the high-flux dialysis on maintaining hemodialysis patients. Methods60 hemodialysis patients were randomly divided into the ordinary PMMA membrane dialyzer group,the ordinary polysulfone membrane dialyzer group and the high-flux dialyzer group with 20 patients in each group.Before and after the single hemodialysis,the removing effect of serum β2- microglobulin (β2-MG)in the 3 kinds of dialyzer,and cholesterol,triglyceride,low density lipoprotein changes after 6 months were compared. ResultsThe ordinary PMMA membrane dialyzer group and high-flux dialyzer group can reduce the concentration of β2-MG,while the high-flux dialyzer group showed more significant effect.On the aspect of lipid metabolism,in the high-flux dialyzer group,serum total cholesterol,triglycerides and LDL levels decreased significantly,while the ordinary dialysis group had no significant change. ConclusionsThe high-flux dialysis can improve the dialysis efficiency,life quality and reduce the complications of patients.

Objective: To examine the causal relationships between obesity, peripheral blood lipid indicators and non-small cell lung cancer (NSCLC) using Mendelian randomization (MR) method, so as to provide the basis for developing NSCLC prevention and control strategies. Methods: Genetic variation data of three obesity evaluation indicators, including body mass index (BMI), body fat ratio (BFR) and waist-to-hip ratio (WHR), and seven peripheral blood lipid indicators, including triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB) and lipoprotein a [LP (a)] were collected through genome-wide association studies (GWAS) and related public databases. Potential causal relationships between obesity, peripheral blood lipid indicators and NSCLC were analyzed using inverse-variance weighted (IVW) method and multivariable MR analysis upon a random effect model. Heterogeneity and horizontal pleiotropy of instrumental variables were evaluated using Cochran's Q test and MR-Egger regression. Results: There was statistically association between BMI with NSCLC (OR=1.256, 95%CI: 1.087-1.451); there were no statistically associations between BFR, WHR, seven peripheral blood lipid indicators and NSCLC (all P>0.005). There was heterogeneity in the association between BMI, BFR, WHR, TG, HDL-C and NSCLC (all P<0.05); no horizontal pleiotropy of instrumental variables was found (all P>0.05). There was no statistically association between BMI and NSCLC after adjusting BFR (OR=1.367, 95%CI: 0.878-2.128); there was still statistically association between BMI and NSCLC after adjusting WHR and peripheral blood lipid indicators (both P<0.05). Conclusions The increase of BMI is associated with the increased risk of NSCLC incidence. BFR may be a potential influencing factor for the association between BMI and NSCLC.

OBJECTIVE:To establish a HPLC method for simultaneous determination of chlorogenic acid and cefazolin in rat plasma.METHODS: Chromatographic determination was performed on spherisorb C18 column with methyl alcohol- 0. 1mol/L potassium ethydrogen phosphate(30: 70v/v, pH 3.0)as the mobile phase and a flow rate of 1.2ml/min.Detection wavelengthes were UV 275nm for chlorogenic acid and 326nm for cefazolin.The concentrations of chlorogenic acid and cefazolin in rat plasma were detected.RESULTS: The calibration curves were linear with the correlation coefficients of 0.997 and 0.998, repectively.The RSDs for the between- day and within- day were both lower than 4% for chlorogenic acid and 6% for cefazolin, respective.The mean recoveries were 93.30%, 93.35% and 96.40% for chlorogenic acid, and 93.41%, 96.60% and 92.36% for cefazolin at large, middle and low dosages, respectively.The concentrations of cefazolin in rat plasma were decreased in coadministration with chlorogenic acid.CONCLUSION: The study provides a simple method for simultaneous determination of the plasma levels of chlorogenic acid and cefazolin.

Objective To establish a successful model for pancreaticoduodenal allotransplantation with enteric drainage in piglet and surveillance acute rejection by biopsy.Methods We implemented the model same as protocol of clinical pancrease transplantation.40 piglets were divided into donors and recipients randomly.20 times experimental operation were finished. The total pancreas with a short segment of duodenum was transplanted to a recipient by anastomoses of vessels to the recipient iliac vessels and small bowel segment to the jejunum with enteric drainage. During operation, mean arterial pressure(MAP), central venous pressure(CVP)were monitored. The levels of amylase activity in blood were investigated.Doppler color blood flow ultrasonography was used to evaluate blood flow of pancreatic allografts,and ultrasound-guided percutaneous pancreas allograft biopsy and histopathologic examination were performed.Results The successful rate of operation was 90%. Recipient's MAP was decreased after the reopening of inosculated blood vessels.(P

Objective To investigate the relationships between the expressions of intercellular adhesion molecule 1(ICAM-1),heat shock protein 70(HSP70) and acute rejection after pancreas allotransplantation in miniature swine.Methods Ultrasound guided biopsies of the pancreas and histopathologic examination were performed after the miniature swine models of pancreas allotransplantation were established.According to the histological change,the samples were divided into group Ⅰ(no rejection),group Ⅱ(mild acute rejection),group Ⅲ(moderate acute rejection)and group Ⅳ(serious acute rejection).The expressions of ICAM-1 and HSP70 were analyzed with immunohistochemistry and imaging.Results The expressions of ICAM-1 and HSP70 were increased when acute rejection occurred after pancreas allotransplantation in miniature swine.The levels of ICAM-1 and HSP70 were sequentially high when acute rejection was serious.Conclusion ICAM-1 and HSP70 were involved in pancreas allograft rejection and useful for early diagnosis of acute rejection after pancreas transplantation.
