1.Importance and Effective Ways of Developing the Doctor-patient Communication Skills for the Oncology Medical Students
Chinese Medical Ethics 2015;(4):572-574
At present, oncology medical student in our country has many communication problems, such as communication awareness is not strong,the lack of communication,communication is not enough self-confidence and other issues.To improve the communication ability between doctors and patients for the oncology professional medical students:it is the necessary premise for correct implementation of diagnosis and treatment, an effective way to reduce medical disputes, adapt to the demand of the development of higher medical education.And pointed out the effective ways to improve the ability of doctor-patient communication:to set up the doctor-patient communi-cation and tumor department before the internship training course;establishlisten with your heart and professional guidancemode;with teacher actively guiding; learn to empathymode; adhere to the concept of taking pa-tients as the center.
2.Vasovagal syncope and serotonergic system
International Journal of Pediatrics 2010;37(2):145-148
The role of serotonergic system in vasovagal syncope (VVS) has been more concerned.Serotonin is a kind of neurotransmitter which is widely distributed in central nervous system.There are kinds of serotonergic receptors on postsynaptic membrane,among which 5-HT1A receptors participate in the mechanism of central blood pressure depression and promote the release of hormones such as prolactin and adrenocorticotrophic hormone.Acute administration of selective serotonin reuptake inhibitors (SSRIs) during head-up tilt test (HUT) blocks the reuptake of serotonin in the synapse space and thus increases stimulation of the serotonin receptors,which induces syncope episode.Long-term administration of SSRIs downregulates the postsynaptic serotonergic receptors,thus it weakens the reaction to the rapid change of serotonin concentration, which results in rapid depression of sympathic nerves and prevention of syncope episode.These demonstrate that central serotonergic system may participate in the pathogenesis of VVS and SSRIs are important for the diagnosis and treatment of VVS.

ObjectiveTo determine the possibility of r eal-time perfusion imaging in the quantitative evaluation of myocardial perfusion in various segments of left ventricle. MethodsImages of ten anesthetized dogs were obtained at the mid-papillary muscle short-axis view with a real-time imaging system. Mechanical index (MI) was adjusted to 0.1 , 0.2 and 0.4 respectively, and frame rate was set at 20 Hz. Optison was infused intravenously at a rate of 0.1 , 0.2 and 0.5 ml/min, respectively. Images were recorded for 150 real-time frames commencing immediately after a couple of Doppler bursts. Myocardial opacification was assessed both visually and quantitatively for six segments of left ventricle (antero- and infero-septum, inferior, posterior, lateral and anterior wall). Myocardial signal intensity versus real-time frame curves were made and fitted to an exponential function: Y=A(1-e -?t ). ResultsUsing low MI (MI= 0.1 or 0.2 ) and with continuously infusion of Optison at a rate of 0.2 or 0.5 ml/min, real-time imaging resulted in sufficient myocardial opacification and left ventricular endocardial border definition, and displayed myocardial thickening and wall motion simultaneously. ConclusionsReal-time imaging has a potential in the quantitative assessment of myocardial perfusion, and allows simultaneous assessment of perfusion and myocardial function.

Objective To study the relationship of fatty acid binding protein-2(FABP2)and apolipoprotein E(ApoE)with coronary heart disease(CHD)in type-2 diabetes mellitus(T2DM)patients.Methods FABP2 and ApoE gene polymorphisms were detected by PCR-RFLP.At the same time all CHD in T2DM patients' serum triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol were(HDLC),low-density lipoprotein cholesterol(LDLC)were detected.Results The T-allele frequencies of FABP2 were higher(P
9.Payment Reform of Medical Insurance Payment: Commentary of International and Domestic Research Progress and China's Practice
Chinese Health Economics 2017;36(4):36-39
The reform for medical insurance payment was the important method for standardizing medical service provider behavior,controlling costs and improving efficiency,which was also the important measurement for further improve and implement the reform of drug and health system.Since the new medical reform in 2009,the central and local government had paid more attention on the role of medical insurance payment reform.Local medical departments of different places implemented reform pilots.Through summarizing the foreign and domestic researches around capitation,bundle payment and global payment,the experiences and effectiveness of these pilots were evaluated so as to provide corresponding policy implications.

With the constant development of medical science and technology, great changes have taken place in the role of medico-technical departments. In light of the basic characteristics and development situation of medico-technical departments in modern hospitals, the paper proposes the following ways to step up their management: ①enhancing organizational management and raising the level of scientific management; ②reinforcing standardized management and improving the quality of diagnosis and treatment; ③tightening personnel management and bettering the quality of technical personnel; ④strengthening horizontal ties and coordinating relations with clinical departments; ⑤augmenting disciplinary integration and bringing into full play the role of advantaged specialty groups; ⑥giving full play to the “two initiatives” and setting up a highly efficient operational mechanism within the departments.
