Objective To observe and compare the functions of two types microencapsulated adult pig pancreatic islets in vivo.Methods The diabetic rats induced by streptozocin were divided into four groups:control group,non-encapsulated islet transplantation group,encapsulated islet with sodium alginate membrane transplantation group and encapsulated islet with agarose membrane transplantation group.All rats received intraperitoneal of islet transplantation.Results There were no significant difference in mean level of the blood glucose before transplantation among four groups.On the 7th day after transplantation,the mean level of the blood glucose in four groups were (22 67?1 15)mmol/L,(18 58?2 66)mmol/L(12 27?1 36)mmol/L and (12 38?2 68) mmol/L,respectively.There were significant difference between two encapsulated islet groups as compared with the other two groups(P

OBJECTIVE:To build the off-label drug use control system,and to realize automatic prompt for off-label drug use by system when physicians prescribed drugs. METHODS:The module and flow chart of off-label drug use control system were de-signed based on B/S structure. The drugs of the prescriptions were verified one by one in terms of drug indication,drug dosage, age and gender of patient,route of administration,etc. The system prompted automatically off-label drug use when drug use didn’t agree with preset value;at the same time,the management effect of the system was evaluated by taken the amount of attention about antibiotics medical orders as an example. RESULTS:At present,265 kinds of drugs were involved in the system designed by our hospital. Since the system was applied,the system had prompted more than 50 thousand items of off-label drug use prescrip-tions/medical orders,accounting for 0.3% of total. Among the types of off-label drug use,the most number of medical orders were over single dose(745 items),followed by extra-indication(706 items)and over daily dose(671 items). Within 3 months after sys-tem used,the attention numbers of antibiotics medical orders of over daily dose decreased month by month. CONCLUSIONS:Es-tablished off-label drug use control system of our hospital has a stable running and convenient manipulation,and contains powerful practicability. It can monitor off-label drug use of some drugs.

Objective To observe the clinical effects of transmission straight wire appliance on the treatment of AngleⅡ1 malocclusion and explore its mechanism.Methods Thirteen AngleⅡ1 malocclusion patients (6 males and 7 females) were treated with the appliance by extracting 4 first premolars or 2 first maxillary premolars.The results of cephalometric measurements before and after treatment were statistically analyzed.Results The average treatment time of 13 cases was 15.6 months.The overbite's treatment cost 4.2 months averagely.Overbite,overjet and molar relationship were turned to normal (only one adult case had complete distal in the molar relationship by extracting 2 first maxillary premolar) and lateral appearances were improved after treatment.The results of cephalometric analysis showed that the changes of SNB,ANB,U1-NA angle,L1-NB angle,U1-LI angle,U1-NA length,L1-NB length,L6-MP length,L1C-MP length,overbite,and overjet were of high statistical significance (P0.05).Conclusion Transmission straight wire appliance can quickly and efficiently correct AngleⅡ1 malocclusion.

ObjectiveTo investigate the effect of neuropeptide substance P on airway resiatance in rats with asthma.MethodsSixty Wistar rats were randomly divided into 3 groups including normal control group(n =20),asthma group(n =20) and substance P group(n =20).Asthmatic rat model was established.We detected inspiratory resistance and expiratory resistance in the airway of rats in each group with the intervention of different concentrations (0.062 5,0.125 0,0.250 0,0.5000 mg/ml) of methacholine(MCh) by using animal pulmonary function analyzer.Substance P group rats were given substance P ( 10-7 mol/L,0.2 ml) when airway resistance was detected.ResultsWith the increase in MCh concentration,the increase in airway resistance in rats was found,rat airway inspiratory resistance and expiratory resistance were all positively correlated with the concentration of MCh ( r=0.947,P＜0.05 ; r=0.965,P＜0.05 ).With the intervention of different concentration of Mch (0.0625,0.125 0,0.2500,0.5000 mg/ml),the significant differences were found among the three groups in rat airway inspiratory resistance ( F=73.4,89.3,91.2,106.4,P＜0.05) and expiratory resistance(F=67.3,77.5,83.4,126.5,P＜0.05).Airway resistance to MCh concentration response curves were shifted upward significantly in asthma group compared with normal control group and in substance P group compared with asthma group.Inspiratory resistance and expiratory resistancc in asthma group were significantly increased compared with normal control group( P＜0.05)and in sutstance P group compared with asthma group( P＜0.05 ).ConclusionSubstance P can increase asthmatic rat's airway resistance and the airway resistance increase with the increasing of MCh concentration.

The clinical and laboratory data of 206 healthy subjects and 271 type 2 diabetic patients were collected. The partial correlation analysis and multiple linear regression analysis showed that serum bilirubin was positively correlated with fasting C-peptide, postprandial C-peptide, and the difference between postprandial C-peptide and fasting C-peptide levels(β=0. 171, 0. 111,0. 052,P<0. 05 or P<0. 01).

0.05.Food appetite and physical status were improved in most of the patients after the treatment of peritoneal dialysis. The serum albumin level after peritoneal dialysis was significant higher as compared with the pre-dialysis state,(37.1?4.4)g/L vs (33.7?5.4) g/L,P

Objective To investigate the effect of probucol on Sertoli cell injury induced by oxygen-glucose deprivation/reoxygenation(OGD/R)and mechanism. Methods Primary Sertoli cells treated with oxygen glucose deprivation for 2 h and reoxygenation for 3 h were modeled. We incubated Sertoli cells with probucol in a concentration of 5,10,and 20 μmol/L from reoxygenation to the end. The cell viability was evaluated using Cell Proliferation Assay kit. ROS production was observed by flow cytometry. The levels of MDA ,iron and GSH or the activity of glutathione-dependent peroxidase were measured by Assay Kit. Results The ferroptosis inhibitors pre-vented cell death(P < 0.01). The cell death rate was decreased by probucol in time- and dose-dependent manner (P < 0.01). Meanwhile, probucol caused increase of ROS,MDA,GSH content and GPXs activity(P < 0.05). Conclusion Probucol protects Sertoli cells from OGD/R damage via inhibiting lipid peroxidation-mediated ferroptosis.
