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.

In recent years, scientists paid close attention to the studies of 3D printing in cardiovascular tissue engineer-ing, which has made some advances.But how to promote cardiovascular tissue engineering for clinical application still needs deeper research.Here we discussed from three cardiovascular tissues ( myocardial tissue, heart valves, coronary) , which at-tempted to retrospect the current progress of 3 D printing in cardiovascular tissue engineering and provided a guidance of further investigations.
5.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.

Objective To map the approximate transcription initiation site of STK11/LKB1 and identify its potential promoter region. Methods All reported transcripts of STK11/LKB1 were colllected through searching online database. The “first exon”, “first intron” and 5' UTR upstream gDNA sequence of STK11/LKB1 were analysed by MethPrimer and FiretEF to predict the CpG island and possible transcription initiation site, respectively. The STK11/LKB1 gDNA sequence was also analysed by softwares such as PromoterInspector to predict the probable promoter region. Results Among all the reported transcripts of STK11/LKB1, 5'UTR of BC007981 was the longest. STK11/LKB1 gene was a typical CpG island associated gene. There was no exon in the upstream region of the “first exon”, and 5'UTR in BC007981 was close to transcription initiation site. Promoters were predicted in the BC007981 5' upstream 200~400bp region. Conclusion The 5'UTR of STK11/LKB1 approaches the transcription initiation site. The transcription initiation site of STK11/LKB1 gene in several hundreds bp region of 5'UTR upstream may be indentified. The data will benefit further research on the trascriptional regulation of STK11/LKB1 through experimental methods.

Objective To study the changes of insulin resistance due to severe short-term fluctuations of body mass in simple obese patients. Methods 94 women with simple obesity, were treated by low caloric and high protein diet for two months. A series of examinations were taken before and after the treatment. Results After two months, weight, body mass index (BMI), waist, hip, fasting serum insulin and HOMA-IR reduced significantly ( P <0. 01 or P < 0.05 ). But after 6 months follow-up,these data began to regain. After 12 months ,these data were not significantly different. Fasting serum insulin and HOMA-IR increased ( P < 0. 05). Conclusions The low caloric and high protein diet combined acupuncture or cupping could reduce weight. But 44% patients weight rebound, and HOMA-IR increased.

Objective To investigate the resistance of multi-drug resistant Acinetobacter baumannii against aminoglycosides and its resistance genes.Methods The minimal inhibitory concentrations (MICs) of seven antimicrobials (gentamicin, amikacin, tobramycine, netilmicin, neomycin, streptomycin and kanamycin) against 20 strains of multi-drug resistant Acinetobacter baumannii were detected by agar dilution method. Meanwhile, two resistance genes of aminoglycoside nucleotidyltransferase were amplified by PCR and vertified by DNA sequencer.Results It was found that MIC50 and MIC90 of gentamicin, amikacin, streptomycin and kanamycin in 20 strains of Acinetobacter baumannii were all above 1 024 mg/L, and their resistant rates were 95%, 95%, 100% and 90% respectively, while the resistant rates of tobramycin, netilmicin and neomycin were 85%, 90% and 40% respectively. Two aminoglycoside-modification genes ant(2″)-Ⅰ and ant(3″)-Ⅰ were detected in 20 strains, with 55% and 80% of positive rate respectively. The double positive rate of two resistance genes was 50%.Conclusion The resistance of multi-drug resistant Acinetobacter baumannii against aminoglycosides was closely associated with ant(2″)-Ⅰ and ant(3″)-Ⅰ genes.
