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 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.

In recent years, much attention has been paid to arterial stiffness detection,but the relation between arterial stiffness and cerebrovascular disease has not been fully elucidated.This article reviews the detective methods of arterial stiffness and its relationship between the risk factors for cerebrovascular disease, ischemic stroke (including asymptomatic cerebral infarction) and cerebral hemorrhage.
