Based on the basic requirement of medical education criteria,we reform courses by improving the goal,content,form and teaching method,and search for the method of improving the quality of teaching and cultivating.

Physical performance is an ability with which the sufferers of lumbar disc herniation(LDH) achieve daily work and basic physical activity,including daily activities(such as the diverting movement from standing to sitting),functioning state of nerves and muscles,dailyworking ability and walking gait,etc.;abilities of body performance relative to pains,such as walking ten meters with loads,sit-stand test and Tread mill walk,etc.Most of current rehabilitation evaluation may be influenced by the subjective factors of the examinee or the examiner,but intelligent device for energy expenditure and activity(IDEEA) may be helpful to evaluate physical performance of the LDH patients in a complete,quantity-fixing,systematic and dynamic way.

Objective To investigate the value of left ventricular function in patients with chronic pulmonary heart disease(CPHD) using strain rate imaging (SRI).Methods This study included 64 patients with CPHD (30 patients with compensatory function and 34 with decompensatory function) and 30 normal control.Peak systolic strain rate (SRs),peak early diastolic strain rate (SRe) and peak late diastolic strain rate (SRa)of left ventricular basal and middle segments were measured,and then mean peak strain rate (mSR) was calculated.The above digital parameters were analyzed compared with the conventional echocardiographic indices.Results The indices (mSRs,mSRe,mSRe/mSRa)in CPHD were reduced and mSRa increased as compared with those in controls (all P=0.000).And the above indices showed the same change when decompensatory group was compared with compensatory group (P=0.000,0.038,0.015,0.001).Negative correlation was noted between LVEF and mSRs in patients with CPHD (r=0.75,0.82;P=0.000).Conclusions LVEF is negatively related with mSRs in CPHD patients.mSRs can reflect the status of left ventricular function.SRI is a more sensitive tool in quantitative evaluation of left function of CPHD.

Objective To establish an RP-HPLC method for determining serum level of valproate.Methods A symmetryshield RP18 column (5?m,3.9mm?150mm) was used.The mobile phase,methanol-water(80:20) was used at a flow rate of 1.0ml/min.The detector was Waters 2487 dual?absorbance detector,which was set at the wavelength of 248nm.Serum sample was extracted with 2ml acetic n-hexane,then valproic acid in organic layer was derived by adding into?-bromoacetophenone,and cyclohcxanecarboxyiic acid was selected as an internal stan- dard.Results The calibration curve was linear in the range of 5.0 to 250.0vtg/ml.The average recovery rate was 98.23%,and the RSD within-day and between-day were both less than 3 %.Conclusion This method is suitable for therapeutic drug monitoring of phenytoin.

Objective To learn the awareness rate of HIV/Syphilis knowledge,condom usage,group behaviors and the infections among men who have sex with men (MSM)in Zhuhai and provide scientific foundation for preparing control measures.Methods The internet community was used for calling MSM to join the research.A MSM survey questionnaire was used to collect messages in the place of HIV Voluntary Counseling & Testing(VCT).The blood samples were collected to proceed biological detection.Re-sults Total 247 MSMs were tested,positive rates of HIV,TP specific antibody and non-specific antibody were 8.10% (20/247), 13.36%(33/247)and 10.72% (24/247).The separation between cognition and behavior was common existed in such population. HIV/syphilis infection rates were significant different between MSMs who had multiple sexual partners and those who did not. Conclusion Because the high risk behaviors are commonly existed among MSM in Zhuhai,the prevalence rates of HIV/Syphilis in them are high.It is necessary promote the screening of HIV/Syphilis,enhance the health education of disease control and block the transmission to develop a safe awareness and behaviors in MSM.

Objective: To investigate the negative mood status of nurses and patients in different hospitals. Methods: Mood of the nurses and patients from a tumor hospital and a general hospital were assessed with SDS, SAS and by professional assessment with HAMA and HAMD. Results: The rates of anxiety and depression of nurses and patients were both significantly higher than that of the normal group, however, there was no correlation between the bad mood of the patients and the nurses. Negative mood status of the nurses was significantly associated with job stress (r=0.335, 0.392,P

We investigated the current situation about free-ranging dogs infection with plague and provided relevant data for plague prevention and control in Karamay City.We examined the dog serum F1 antibody by indirect hemagglutination assay (IHA).Results showed that the F1 antibody was found in 1 of 13 dogs serum samples,and the positive rate was 7.69％.The free-ranging dogs plays an important role in controlling animal plague epidemic,and there are potential risk for local people's infection of plague.
