Objective To determine the prevalence and clinical features of peripancreatic vascular abnormalities in patients with pancreatitis.Methods The clinical data of 102 pancreatitis patients between January 2013 to December 2014 in the General Hospital of Shenyang Military Command who underwent contrast enhanced CT or contrast enhanced MRI scans were retrospectively analyzed.The radiological features of peripancreatic vascular abnormalities in such patients were examined, and the clinical features of pancreatitis patients with or without peripancreatic vascular abnormalities were investigated.Results Peripancreatic vascular abnormalities were found in 18 patients(17.6%), and vascular abnormalities were relatively common in portal vessels.No significant differences were observed on the age at onset, gender ratio, smoking status, alcohol consumption and length of stay between patients with and without peripancreatic vascular abnormalities.Compared with those without peripancreatic vascular abnormalities, patients with peripancreatic vascular abnormalities had a significantly higher incidence of peripancreatic fluid collection, pancreatic pseudocyst and gastric varices, and the differences were statistically significant(all P<0.05).Conclusions Peripancreatic vascular abnormalities can be complicated with pancreatitis.Enhanced CT or enhanced MRI were valuable in the diagnosis.Pancreatic pseudocyst, peripancreatic fluid collection and gastric varices were more common in pancreatitis complicated with peripancreatic vascular abnormalities.

Objective To investigate the effects of metformin on blood glucose control and body weight management in over-weight patients with newly diagnosed type 2 diabetes mellitus (T2DM).Methods A retrospective study was performed in T2DM patients who were treated with metaformin (male 38,female 23,mean age (50.8 ± 7.9) years old).Based on body mass index (BMI),all the participants were assigned to obese,over-weight and normal weight group.Analysis of variance and multivariate analysis were used to confirm the effects of metformin on blood glucose and body weight.Results Fasting blood glucose (FBG),HbA1 c and BMI were significantly reduced over 2 years.In comparison with baseline,BMI of the obesity and overweight group was significantly decreased during follow up (P ＜ 0.05),while BMI of the normal weight group increased by 0.7 kg/m2.At baseline,FBS and HbAlc of the obese group were lower than those of the normal weight group (FBS (7.3 ± 0.8) vs.(11.8 ± 4.8) mmol/L,P ＜ 0.05 ; HbA1 c (6.8 ± 1.2) ％ vs.(8.5 ±3.1)％,P ＜0.05),whereas insulin level was higher than that of the normal weight group ((2.20 ± 0.36) vs.(1.87 ± 0.29) U,P ＜ 0.05).At 2 years,HbA1 c was reduced on average by 2.5％,1.4％ and 1.9％ in the obesity,over-weight and normal weight group,respectively.Conclusions The present study demonstrates the beneficial effect of metformin on newly diagnosed diabetics,especially obese patients.

Objective To survey the current working status of general practitioners (GPs) who received residency training in Shanghai.Methods The current status of general practitioners,who completed residency training in Shanghai from 2013 to 2014,was surveyed with self-designed questionnaire by e-mail.The survey items included current employers,job specification,clinical practice,teaching,scientific research and so on.Results Three hundred and thirteen out of 377 GPs,who completed residency training from 2007 to 2012,participated in the survey (83.0％),including 85 males and 228 females with a mean age of (31.2 ± 2.6) years.Among all participants,298 (95.2％) worked in community health service centers,12.8％ (40/313) of them were involved in general practice teaching,9.9％ (31/313) undertook management,9.3％ (29/313) did academic research in community,and 7.7％ (24/313) had chance for overseas study.The survey also showed that 134 person/times received various commendations and awards.Conclusion Most GPs who completed residency training are undertaking clinical practice in community health service centers,and they are also well involved in management,teaching,and research.

Aim To investigate the interactions be-tween the neuroinflammation caused by lipopolysaccha-ride(LPS) and brain CYP2E1.Methods The human cholinergic neuroblastoma cell line IMR-32 was treated with LPS ( 0.1 mg · L-1 , 1.0 mg · L-1 ) , and the LDH and SOD activities were determined after 24 h in-cubation .In order to determine the roles of MAPK sig-naling pathway in the regulation of CYP 2E1 by LPS, the IMR-32 cells were treated with p38 pathway inhibi-tor SB203580 or ERK pathway inhibitor U 0126 for 45 min before the incubation with LPS .The human do-paminergic neuroblastoma cell line SH-SY5Y with CYP2 E1 over-expression was established . The LDH and SOD activities were determined in SH-SY5 Y cells over-expressed CYP2 E1 and control cells treated with LPS(0.1 mg· L-1 , 1.0 mg· L-1 ) for 24 h.Results
The levels of LDH in IMR-32 cells treated with high-dose LPS were increased by 1.38-fold ( P <0.01 ) compared with the control group , and the levels of SOD reduced by 15.0%( P <0.01 ) .Compared with the control, CYP2E1 mRNA and protein levels in IMR-32 cells treated with high-dose LPS were increased by 1.25-fold(P<0.01) and 1.19-fold(P<0.05).The up-regulation of CYP2E1 by LPS could be attenuated by SB203580 and U0126 pretreatment.Compared with the control cells, the CYP2E1 over-expression in-creased LDH levels by 1.28-fold ( P<0.01 ) and de-creased SOD levels by 3.53-fold ( P<0.01 ) after the low-dose of LPS treatment .The CYP2E1 over-expres-sion increased LDH levels by 1.54-fold ( P <0.01 ) and decreased SOD levels by 2.17-fold( P<0.01) af-ter the high-dose of LPS treatment , compared with the control cells.Conclusions LPS can induce CYP2E1 mRNA and protein levels , and the p38 and ERK sig-naling pathway may be involved in the regulation .The elevated CYP2 E1 levels aggravate the damage to neuro-nal cells caused by LPS .Brain CYP2E1 may be an im-portant contributing factor to the pathological process of neuroinflammatory injury .

Objective To investigate the expression of TLR2 in colon mucosa of ulcerative colitis (UC) and to analyze the correlation with clinical activity and endoscopic grading. Methods The biopsies from 47 UC patients and 13 healthy controls were collected, and the expression of TLR2 protein and mRNA in colonic mucosa was determined by Western Blot and semi-quantitative RT-PCR, respectively. The patients were graded according to endoscopic and clinical findings. Results The expressions of TLR2 protein and TLR2 mRNA in UC patients were significantly increased than those in healthy controls, which was correlated with the progression of the disease. Conclusion The expressions of TLR2 protein and TLR2 mRNA in colon mucosa from UC patients might be used as a marker for disease activity.

OBJECTIVETo compare the osseointegration and corrosion of different kind of coatings on pure titanium.

METHODSBy plasma spraying technology, nitrogen silicon zirconium-hydroxylapatite (ZrSiN-HA) compound coating was prepared on the surface of pure titanium and the pure titanium was implanted with the mandible of the experimental animal. The superficial appearance of the compound coating was observed and analyzed by scanning electron microscope (SEM). The ZrSiN-HA, nitrogen silicon zirconium (ZrSiN), hydroxylapatite (HA) and pure titanium were compared and examined. In the four groups, the bone binding force of coatings were detected, and the superficial appearance of the break regions were observed by the electronic multipurpose material testing aircraft. In the four groups, the anticorrosive of coatings were compared and examined on the electrochemistry corrosion testing system.

RESULTSExperimental results indicated that the implant surface sprayed with the ZrSiN-HA was more compact than that sprayed with HA. The crystallization was obvious. Compared with the other coatings, the bone binding force of the ZrSiN-HA coating was the highest, and its anticorrosive performance was the strongest.

CONCLUSIONThe application of ZrSiN-HA coating is advantageous to the long-term retention of implant, and it has huge latent application value to dental dummy.

Objective To evaluate the clinical capability of young general practitioners (GPs) in communities in Shanghai.Methods A cross-sectional survey on clinical ability of young GPs was adopted from October to December 2014.Total 211 GPs aged (31 ± 2) years (25-35) from 17 districts of Shanghai participated in the study.Written examination and objective structured clinical examination (OSCE) was applied in the evaluation.Results All 211 GPs (63 male and 148 females) completed the assessment.The overall score of the assessment was (602 ± 83) and the pass rate was 62.6％ (132/211).In written examination the average score was (64 ±7) and the pass rate was 72.1％ (152/211).In OSCE,the highest score (80 ± 15) and pass rate (92.9％,196/211) was in CPR skill,followed by communication skill [average score:(76 ± 15) and pass rate:85.8％ (181/211)].The lowest average score was physical examination (47 ± 15) with a pass rate of 26.1％ (55/211),followed by electrocardiogram reading [average score:(84 ±31) and pass rate:39.8％ (84/211)].In basic operation station,the lowest score was using funduscope and gynecologial examination (29.8％ and 45.4％,respectively).Conclusion Young GPs in Shanghai communities basically master clinical skills,but also have some deficiencies,the training in certain skills need to be strengthened.

Objective To compare the efficacy and efficiency of simulation-based training of flexible fibreoptic intubation in novices with virtual reality simulator.Methods A total of 46 anaesthesia residents in their first stage of training in anaesthesiology with no experience in flexible fibreoptic intubation at Peking University People's Hospital were enrolled in the study,and were divided into 2 groups randomly,which were virtual reality simulator group (group S,n=23) and manikin group (group M,n=23).The group S was then trained for 25 times on simulator,while the group M did the same processes on manikin.After training,participants in both groups had their performance assessed with the fibrescope evaluated through the oral route using a simulation manikin,who were instructed to attempt to advance the fibrescope 5 consecutive times to view the carina in the shortest amount of time.The time required to view the carina of each practice during training in both groups were recorded as pooled data to construct group learning curves with the application of SPSS 20.0.By using repeated measures analysis of variance and Ttest,the procedure time and global rating scale (GRS) of fibreoptic bronchoscope manipulation ability were compared between groups,so did the participant's confidence between before and after the training both within-subjects and between-subjects.Results The plateaus in the learning curves were achieved after 19 (15,26) practice sessions in group S and 24 (19,31) in group M,respectively.There was no significant difference in the procedure time [(13.7 ± 6.6) s and (11.9 ±4.1) s] and GRS [(3.9 ±0.4) vs.(3.7 ±0.3)]between groups.There were significant increases in participant's confidences in both groups after training [group S:(1.8 ± 0.5) vs.(3.9 ± 0.6),t=10.928,P=0.000;group M:(2.0 ± 0.7) vs.(3.9 ± 0.5),t=15.306,P=0.000],but there was no significant difference between groups.Conclusion The simulation-based training of flexible fibreoptic intubation in novices with virtual reality simulator is more efficient than the one with manikin,but the similar effects can be achieved in both modalities,after adequate trainings.In the related training a balance between time cost and economic cost should be considered and the appropriate teaching methods and forms should be taken.

Objective To assess community health service ability of general practitioners (GPs) with the Standardized General Practitioner Training(SGPT) in Shanghai.Methods One hundred and four GPs receiving SGPT and matched 102 GPs without SGPT were enrolled in this retrospective cohort study from September to November in 2014.Community health service ability,including abilities in basic medical service and public health service were assessed and compared between two groups.Written examination was applied in the public health services ability assessment.Objective structured clinical examination (OSCE) was applied for evaluation of basic medical service abilities.Results The scores of written examination in GPs with SGPT were higher than those without SGPT[(66 ±4) vs.(62 ±7),P ＜0.01].The OSCE scores in GP with SGPT were higher than those without SGPT [(494 ± 78) vs.(448 ± 80),P ＜ 0.01].GPs with SGPT also abtained the higher scores in consultation competence and clinical skills assessment [(245 ± 44) vs.(225 ±40),P＜0.01;(252 ±59) vs.(225 ±61),P ＜0.01].In OSCE,GPs with SGPT got higher score than those without SGPT in 5 stations (medical history collection,doctor-patient communication,basic operation,ECG interpretation,and CPR) (all P ＜ 0.01);however,no significant differences were observed in 3 stations (physical examination,case analysis and X-ray interpretation) between two groups (all P ＞ 0.05).Conclusions GPs with SGPT have better basic medical service and public health service ability.But some aspects of basic medical service ability need to be strengthened in the training and practice.
