Diagnostics is one of the most important bridge courses for medical students from basic to clinical. Doctor-patient communication runs through the whole process of patient diagnosis and treatment. How to improve medical students' ability of doctor-patient communication? Our teaching team has carried out continuous reform and explored the scientific effective teaching mode. Recently, through the construction of "doctor-patient communication skills" quality online course, efforts have made to build an online and offline blended learning mode, which has gradually realize the integration with diagnostics teaching, and has achieved remarkable results. It also provides a scientific practical basis for the integration of doctor-patient communication and other clinical courses, which is worthy of promotion.

Objective To investigate effects of Danhong on the serum levels of CD137, high-sensitivity C-reactive protein (hs-CRP) and homocysteine (Hcy) in patients with non-ST elevation acute myocardial infarction complicating metabolic syndrome. Methods A total of 126 patients with non-ST elevation acute myocardial infarction complicating metabolic syndrome were enrolled and randomly divided into a conventional treatment group and a Danhong treatment group using a random-digit table, with 63 patients in each group. All patients underwent angiography or percutaneous coronary intervention. The patients in the Danhong treatment group treated with intravenous Danhong 20 ml on the basis of conventional treatment for 1 week. The serum levels of CD137, hs-CRP and Hcy were measured at hospital admission and 10 days after treatment. The severity of coronary artery disease was assessed by the Gensini-score. Results The levels of CD137, hs-CRP and Hcy in both groups after treatment were significantly lower than before treatment (conventional treatment group: t 12.393, 17.408 and 9.458; Danhong treatment group: t 16.110, 17.573 and 13.481; all P<0.01), and the Danhong treatment group were significantly decreased than the conventional treatment group (t 2.815, 3.224 and 3.157, all P<0.01). The serum levels of CD137 and hs-CRP before treatment were significantly correlated with Gensini scores in 126 patients (r 0.720 and 0.562,all P<0.01). Conclusions The serum levels of CD137 and hs-CRP are significantly correlated with the severity of coronary artery disease, intravenous Danhong may has protective effect for coronary artery disease via decreasing CD137 and hs-CRP.

The reform of public medical institutions is a critical and difficult breakthrough in furthering the healthcare system reform in China, for which the performance appraisal of public hospitals can serve an important role. The performance policy documents of tertiary public hospitals, secondary public hospitals and primary medical and health institutions in China since 2019 were compared and analyzed, to systematically identify the similarities and differences and development rules of the three evaluation index systems. The study analyzed the impacts of the three systems on the management of medical institutions and provided reference suggestions for improving their performance evaluation. It was found that all the three systems aim at guiding tertiary public hospitals to evolve from the pattern centering on scale expansion to that on quality and benefits, guiding secondary ones to improve their capacity of medical services, and guiding primary medical institutions to focus on basic medical and public health services. However, these systems lack indexes on hierarchical diagnosis and treatment for secondary hospitals and application of examination results, while national surveillance indexes on primary ones accounted for only 23.8% of all. It is recommended to dynamically adjust both the performance evaluation index system and the surveillance methods, and to enhance the application of examination results and development of supporting policies as well.
