RESUMO
Objective To understand the short-term effect of practice skill training for general practitioners in Guangdong province and to provide scientific basis for improving the training strategy. Methods According to the training outline (Outline of job-transfer training for general practitioner in primary health institutions (trial))of the Ministry of Health,job-transfer training was provided for a total of 451 primary care doctors in economically undeveloped cities for one year. All trainees were investigated before and after training by questionnaire,which were designed by ourselves and included practical skill level and satisfaction degree.SPSS 13.0 software was used to do statistical analysis and data were processed by description analysis,t test,ANOVA and correlation analysis. Results Average self-evaluation scores of practical skills were 136.37 ±21.74 and 169.39 ±17.12 before and after training with significant differences (t=29.028,P=0.000). Scores of all types of practical skills after training were significantly higher than those before training (P<0.000 1). Total satisfaction rate was 91.6%and students were not well satis-fied with training environment and training guarantee. Fac-tors influencing the effect of training included educational background,professional title,doctors' de-sire of training,whether taking part in the general practitioner training or not. The effect of practical training was positively correlated with total satisfaction (r=0.162,P=0.037). Conclusions Remark-able results of practice skill training have been achieved. In the future,more chances for practice should be provided for trainees and contents of skill training should be designed according to the need of community health service,and more attention should be paid to the training project management.
RESUMO
Objective To investigate the mouse liver blood vessel images using phase contrast X-ray imaging with synchrotron radiation. Methods 6 female C57BL/6 mice were randomly divided into two groups, 3 mice in each group. In one group, livers excised after hgated arteries, veins and common bile duct. In another group, iodine infused via the portal vein and drained from inferior vena cave until all the blood in the portal veins and hepatic veins was displaced. After infusion, arteries, veins and common bile duct were ligated and livers were excised. Results Blood vessel images were clearly produced by diffraction enhanced imaging. This method can discriminate vessels down to about 40 μm in diameter without contrast agent. Using a contrasting agent more details could be produced. In one liver lobe, the entire branch of the portal vein could be clearly produced by one by one phase contrast image from the main axial blood vessels of liver lobe to the nine generation of branching. Conclusions Phase contrast imaging has the advantage of good contrast and high spatial resolution.
