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 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

[Objective] To study the pharrnacodynamic effect of Bao Xin Kang on animal models with cardiac insufficiency (CI) . [Methods] CI animal models were established by constricting the abdominal aortae in rabbits. The pathological results in different groups were compared. The hemodynamics indices such as LVEDP and?dp/dtmax and NO level were measured. [Results] Compared with the model group, the high dose of Bao Xin Kang can lessen the hyperplasia and hypertrophy of the myocardium and relieve the pulmonary edema in animals and improve the hemodynamics indices. LVEDP was decreased ( P

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.

Objective To investigate whether enteric nervous system(ENS)involve in mediating the effect of short pulse gastric electrical stimulation on c-fos expression in nucleus tractus solitarius (NTS)and hypothalamus.Methods Fifteen Wistar rats were divided into control group,gastric electrical stimulation(GES)group and ENS free group with 5 rats each.A pair of electrodes was implanted on the gastric serosa.In ENS free group,0.5%benzalkonii chloridum was applied on the serosa during the surgery.A set of short pulse GES with frequency of 20 cpm,pulse width of 300 μs and amplitude of 2 mA was applied via the electrodes for 30 rain in the stimulation group and ENS free group.The c-fos expression in NTS/hypothalamus was detected 1 h after the stimulation.Results The number of neuron with c-fos expression was(71.6±7.4)/HP in NTS group and(63.4±10.8)/HP in ENS free group,both were significantly higher than those in control group(36.4±8.6/HP,P＜0.05).The number of neuron with c-fos expression in hypothalamus was higher in GES[(224.2±47.3)/HP]and ENS free groups[(249.1±44.0)/HP]compared with control group[(90.2±47.3)/HP,P＜0.05].There was no significant difference in c-fos expression in NTS/hypothalamus between GES group and ENS free group(P＞0.05).Conclusions Short pulse gastric electrical stimulation significantly increases c-fos expression in NTS/hypothalamus,which suggests that NTS/hypothalamus may participate in mediating the effect of GES on gastric function.This effect may be not mediated by ENS.
