Objective To discuss how to practise and consummate to shoot and assess the portfilm for radiotherapy. Methods Double radiography technique was used to take a portfilm. The reference mark points (plumbum points) were added into the field at the first exposure and the cross lines drawn based on the plumbum point images were definited as the reference coordinate to the actual field. Then, the portfilm was compared and analyzed with the simulator planning film. Results The images of both plumbum points and block boundaries were distinct in the portfilm, but the resolution and contrast of the tissue structure image was inferior to the ordinary film from simulator. However, all different structures and positions could be identified in order to assess if the actual field coincided with the radiation planning. Conclusions Although the real-time property of the portfilm is inferior to the electric portal image device (EPID), the double radiography portfilm is feasible as an important quality control method in radiation therapy due to its lower price and easier performance. The design of reference points is the key point in this technique.

A clinical emergency skill contest using emergency care simulator (ECS) was carried out　on May 2011.Total 30 family physicians in 10 teams from Shenzhen community health centers participated in　the contest.The performance and the scores of each item were analyzed.The overall score was 61.3 ± 11.9.The average score for general treatment was 33.0 ± 6.9 with a score rate of 66％ (33/50) ; the average　score for cardiopulmonary resuscitation was 23.2 ± 7.2 with a score rate of 57.5％ (23/40) ; the average　team score was lowest (5.0 ± 1.1 ) with a score rate of 50.0％ (5/10).The results indicate that family　physicians should strengthen clinical skill training of emergency care,particularly in on-site response and　teamwork.

Three hundred and nine community health service (CHS) practitioners were selected with randomized cluster sampling for survey with the job satisfaction questionnaire-occupational stress indicator (OSI).Degree of the job satisfaction was (68 ± 12)%.Position, work experience, income,feeling of recognition, degree of motivation, the scope for career development, the space for personal ambition and the relationship between salary and work load were potential influencing factors of job satisfaction to CHS practitioners.The authors suggest to establish the dynamic mechanisms of satisfaction study and to formulate comprehensive and effective incentive measures for CHS practitioners.

Five general practitioners were trained for application of the enhancing CalgaryCambridge guide in consultation.The consultation time in 50 patients were recorded before and after training and the satisfaction degree of patients was investigated by questionnaire survey.Results showed that the length of consultation time after training was longer than that before training (490 s vs 277 s,P ＜ 0.05) and also longer than that of specialists (490 s vs 268 s,P ＜0.05).The overall satisfaction rate of patients was increased after training (72％ vs 88％,P ＜0.05).The results indicate that training of Calgary-Cambridge guide for doctor-patient communication can improve the communication skills of general practitioners.
