Methods Totally 425 subjects were given an eye examination in a community health center. The anterior chamber depth of each subject was examined by one ophthalmologist and two trained community health workers (one nurse and one non-professional health worker) using oblique flashlight test. Inter-observer agreement was determined using the weighted kappa statistic. Results Among the enrolled subjects,148 (35%) were male and 277 (65%) were female. Good agreement was noted in all the three observers. The comparison between the ophthalmologist and the nurse showed a kappa statistic of 0.42 for both eyes (P<0.001). The kappa statistic was 0.54 and 0.52 for right and left eyes respectively between the ophthalmologist and the non-professional health worker (P<0.001). As for agreement between the nurse and the non-professional health worker,the kappa statistic was 0.49 and 0.38 for right and left eyes,respectively (P<0.001). Conclusion The oblique flashlight test may be used as an applicable tool by trained community health workers for screening of shallow anterior chamber and play a role in blindness prevention in community.展开更多

Methods A questionnaire survey was conducted amongst Chinese orthopedic surgeons. A total of 293 surgeons were surveyed concerning five key aspects of thromboembolic prophylaxis after major orthopedic surgery at the proseminar of Chinese guidelines for prevention of venous thromboembolism (VTE) after major orthopedic surgery in January of 2009. Results Totally, 208 surgeons (71.0%) responded, successfully completing the questionnaire. Of them, 57.6% respondents selected combined basic, mechanical, and pharmacologic methods for thromboprophylaxis; 51.0% respondents prefer starting prophylaxis 12-24 hours after surgery; 60.3% surgeons would use chemoprophylaxis for 7-10 days; 47.6% respondents prefer VTE prevention based on patients' special conditions and needs upon discharge. "Safety" was the most repeated and emphasized factor during VTE prophylaxis. Conclusions Multimodal thromboprophylaxis is frequently used after major orthopedic surgery. Half surgeons prefer to start chemoprophylaxis 12-24 hours after surgery. Thromboprophylaxis regimen varies for discharged patients.展开更多

Medical science can be regarded as sacred and holy as a religion for doctors to believe. The common points between them are the basis to successfully integrate them into doctors' faith. Furthermore, we explain that doctors need a faith to believe so as to meet the demand of humanitarian traits we should have and to do better in the scientific work and win in the battles with the diseases.展开更多

Molecular imaging by using isotopic tracers can noninvasively visualize the chemistry or hidden process in the cells and tissues inside the body, obtaining "functional" images to provide early information of any disease and revealing the secrets of life. The vitality of nuclear medicine is its ability to translate bench into new clinical application that can benefits the patients. Although nuclear medicine community in China has made significant achievement with a great effort since 1950s, there are many obstacles to future development. Recommended measures are proposed here in an attempt to solve our existing problems.展开更多
