Objective:To establish a RP-HPLC method with pre-column derivation for determining the content of stilbene glyco-sides in Yening granules. Methods:DNS-Cl was used as the derivation reagent, a Wondasil-C8 column (250 mm × 4. 6 mm, 5 μm) was used as the stationary phase and 30mM ammonium phosphatere gulation (pH 3. 5)-acetonitrile (78∶22) was applied as the mobile phase, a fluorescence detector (λex=370 nm,λem=560 nm) was used, the flow rate was 1. 0 ml·ml-1 , the column temperature was 30℃ and the injection volume was 20 μl. Results: There was no interference from the other substances in the preparation. The linear range of the two stilbene glycosides was 0.071-27.280 mg·ml-1(r=0.999 9). The average recovery was 99.04%(RSD=0. 1%, n= 9). Conclusion:The method is simple, quick, sensitive and accurate, which can be used for the quality control of Ye-ning granules.

Fasting blood ghrelin level was decreased,and postprandial ghrelin descent was suppressed in high-fat diet induced obese rats.Fasting ghrelin concentration,but not postprandial ghrelin concentration,was negatively correlated with body weight,insulin resistance index,and glucose level.

Aim To study the effects of amitriptyline(Ami)on focal cerebral ischemia-reperfusion injury in rats.Methods An animal model of focal cerebral ischemia-reperfusion injury was induced by the middle cerebral artery occlusion(MCAO) by reversibly inserting a nylon thread method.The rats were decapitated after ischemia for 1 hour and reperfusion for 2 hours.The infarct volumes were determined using a 2,3,5-tri-phenyl tetrazolium chloride(TTC) staining and assessed by image analysis system.The neurologic deficit status were evaluated on 0~5 grade scale.The levels of dopamine(DA),norepinephrine(NE),serotonin(5-HT) and its metabolic product~hydroxyindole acetic acid(5-HIAA) in cortex and striatum were measured by fluoro-spectrophotometry.Results Ami treatment exhibited a remarkable reduction in infarct volume and neurologic deficit scores.The monoamines content of cortex and striatum had a significant increase compared with ischemia-reperfusion group.Conclusion Amitriptyline has protective effect on cerebral ischemia-reperfusion injury in rats.The mechanism might be related to reducing the release of NE,DA and 5-HT during cerebral ischemia-reperfusion,attenuating or inhibiting of the neurotoxic effects of monoamine neurotransmitters.

Objective To evaluate the simulation of standardized patients (SP) in objective structured clinical examination (OSCE) for general practice residency training.Methods The simulation levels of 15 SPs were evaluated by 37 examiners with a rating scale of OSCE Examiner Feedback on SP performance from Melbourne University School of Medicine.The evaluation was conducted in history-taking and doctor-patient communication stations of OSCE for general practice residency training.Results The overall scores of SP performance were high and most examiners considered that the performance of SP was realistic and consistent.Among 9 items of rating scale,more than 90％ of the examiners considered that SP performance met or completely met the requirements of OSCE,except the item of preparation for clothing and making up before role playing.Six items of performance in history-taking station and 4 items in doctorpatient communication station reached 100％ satisfaction from the examiners.T test was used to compare the difference of SP performance between the morning and afternoon,and there was no significant difference (P ＞ 0.05).Conclusion The study showed for this group of SPs,the realistic degree and consistency of performance meet the requirements of OSCE,and its stability is not affected by long time continuous performance.

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.

By using the glyoxylic acid to induce fluorescence histochemieal method, the catecholamines (CAs) in the adrenal medulla of rats were demonstrated。The CAs fluorescent intensity was measured with Leitz MPV-2 microflurophotometer. The results showed that the CAs fluorescent intensity in the adrenal medulla of rat with traumatic shock was much decreased than that of the normal control group. The CAs fluorescent intensity was in the adrenal medulla obviously increased after using electroacupuncture (EA) at "Renzhang" and "Chenjiang" points. Our results also indicated that the EA might play a certain role in regulating the level of plasma CAs during the traumatic shock process. Therefore, The depletion of CAs was reduced from the rat's adrenal medulla, this could be one of the benificial factors in using the EA antitraumatic shock.

Objective To determine the serum levels of macrophage migration inhibition factor (MIF) and tumor necrosis factor-α (TNF-α) in patients with vitiligo,and to investigate their clinical significance.Methods The serum concentrations of MIF and TNF-α were determined by enzyme linked immunosorbent assay (ELISA) and radioimmunoassay respectively in 66 patients with vitiligo and 30 healthy controls.Results The patients with vitiligo vulgaris showed a significant higher serum level of MIF and TNF-α compared with the healthy controls ((9.56 ± 1.65) vs.(5.18 ± 0.81 ) μg/L,(2.38 ± 0.37) vs.(1.78 ± 0.21 ) μg/L,both P ＜ 0.01 ).There was a positive correlation between the serum level of MIF and TNF-α (r =0.89,P ＜ 0.05).No statistical difference was observed in the serum levels of MIF or TNF-α between the healthy controls and patients with segmental vitiligo (both P ＞ 0.05).The serum level of MIF was significantly higher in patients with progressive vitiligo than in those with stable vitiligo (P ＜ 0.01 ).Conclusions MIF and TNF-α might play a certain role in the pathogenesis of vitiligo,and MIF may be related to the activity of vitiligo vulgaris.

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.

BACKGROUND:Foreign injectable sulphate calcium has good biocompatibility, injectability and in situimmobilization, moulding based on adaptation to the shape of bone defects, but the price is expensive. OBJECTIVE:To explore the optimal fabricating parameters of bone repair materials with α-calciumsulfate hemihydrates as the main component, and to study the performance and characterization METHODS:α-Calciumsulfate hemihydrates powder was mixed with sodium hyaluronate at liquid-solid-ratios of 0.2, 0.25, 0.3, 0.35, 0.4 mL/g using vapor-heat method to prepare injectable bone materials. Performance, setting time and compressive strength of the injectable bone was detected. The best liquid-solid-ratio was 0.3 mL/g.α-Calcium sulfate hemihydrates powder was mixed with calcium sulfate dihydrate powder (1%, 2%, 3% mass fractionas) to fabricate injectable bone materials. Performance, setting time and compressive strength of the injectable bone was also detected; meanwhile, the biosafety of the injectable bone was determined. Theinjectable bone material that was made at the liquid-solid-ratio of 0.3 mL/g and by 2% calcium sulfate dihydrate was implanted into Ba-ma swine models of thoracic bone defects. At the time points of 8, 16 and 24 weeks after implantation, histological observation was done. RESULTS AND CONCLUSION: The injectable bone material was made at the liquid-solid-ratio of 0.3 mL/g and by 2% calcium sulfate dihydrate. The initial and final setting time was 4.0-5.0 minutes and 8.0-9.0 minutes, respectively. The compressive strength of the injectable bone reached (8.93±0.23) MPa. These findings indicate that the injectable boen material has good performance, initial setting time and compressive strength meeting the requirements of clinical application and good biosafety. Animal experiments show that the injectable bone can provide space for new bone in creeping substitution way by auto-degradation, with osteogenic activity.
