Objective:To understand the current situation of physicians′ competency in China and statistically analyze its influencing factors, hence providing referential evidences for promoting their competency.Methods:The evaluation scale for Chinese physicians′ competency was developed by referring to sophisticated overseas evaluation frameworks. Based on the electronic platform of the medical alliance, stratified sampling was conducted at 39 hospitals in 13 provinces, from which 2 156 physicians were surveyed, and statistical analysis was made on the current situation and influential factor of their competency in 6 dimensions(medical knowledge, diagnosis and treatment, scientific research and teaching, interpersonal communication, spirit of professionalism, population health)Results:The score range in multiple dimensions of physicians′ competency was between 2.85 and 3.89(5 in total), among which spirit of professionalism dimension scores the highest, and teaching and research dimension scores the lowest. Logistic regression analysis shows that their competency level in 6 dimensions is correlated to a range of factors, including gender, degree, title, supervisor qualifications, standardized training program of specialist physicians, and affiliation or not to teaching hospitals( P<0.05). Conclusions:Their overall competency is expected to be elevated. To name a few, they are lack of teaching and research abilities, and need to conduct clinical-oriented scientific research; they are expected to enrich knowledge structure, and need to embrace a wider concept of health; they need to improve their non-technical service abilities, and should further emphasize their humanistic quality; physicians′ practice competency depends upon their extent of medical education, and ensuring the quality of standardized training becomes the key measure.

Objective To investigate the effects of ultrasound radiation force(USRF) on adhering of targeted microbubbles in vivo.Methods A rat model of cremaster muscle Inflammation was developed,and microbubble(MB) or targeted microbubble of intercellular adhesion molecule-1 (MBICAM) was injected through the caudal vein.Immediately after intravenous MB or MBICAM injection,the cremaster was insonated for 5 minutes and the control group was in sham ultrasound exposure.All mice were divided into four groups randomly:① MB + false USRF; ② MB + USRF; ③ MBICAM + false USRF; ④ MBICAM + USRF.Fluorescence microscope was performed in twenty mice to evaluate microbubbles adhesion and video recordings were made with a high-resolution camera.Results The adhesion number of MBICAM was significantly greater in USRF group than that of MBICAM in false USRF group [(43.4 ± 2.1)/view vs (14.8± 1.8)/view,P =0.000].The adhesion number of MB in USRF group was greater than in false USRF group [(6.2 ± 1.3)/view vs (4.6 ± 0.9)/view].But there is no statistical significance (P =0.129).The adhesion number of MBICAM in both USRF group and false USRF group was significantly greater than the adhesion number of MB.Conclusions The ultrasound radiation force can significantly improve the adhesion of targeted microbubbles in vivo.
