2.Construction and application of monitoring platform for medical response to nuclear or radiological emergency
China Medical Equipment 2014;(6):7-10
Objective: In order to implement effectively on-scene medical response to a nuclear or radiological emergency, and also keep track of relevant on-scene audio and video information and monitoring data, we have designed and developed a monitoring platform for medical response to nuclear or radiological emergency. Methods:Based on relevant national standards for emergency response and the features of nuclear or radiological emergency, exploiting modern information technology and monitoring equipments, we formulate the design idea, characteristics, functions and framework of the platform. This platform takes treatment centers for nuclear or radiological injuries, designated medical institutions and medical response teams as main users. Results:We have developed the monitoring platform for medical response to nuclear or radiological emergency. Conclusion:Through the application of this platform, we hope to enhance the preparedness and on-scene response capability for nuclear or radiological emergency, and also provide information support for disposal of nuclear or radiological emergency in the future.

Chinese Journal of Medical Education Research 2013;(12):1278-1281
Graduate medical education, postgraduate medical education and continuing medi-cal education between China and the United States were compared in order to explore a better physi-cian training system of China. The physician training system of the United States has a series of ad-vantages such as strict access system, uniform training standard and closely linked among each stage, etc. We should make clear medical education standards and strengthen the cohesion between each stage, standardize the management mode and perfect the management system and promote regular as-sessment system.
4.Several proteins involved in absorption of cholesterol in small intestine
Military Medical Sciences 2015;(6):472-475
Several proteins are involved in the absorption of cholesterol in small intestine.Niemann-Pick C1 like 1 (NPC1L1) mainly mediates the absorption of cholesterol, and acyl-coenzyme A ( CoA)∶cholesterol acyltransferase 2 (ACAT2) catalyzes the free cholesterol absorpted by intestine into cholesterol ester,while unesterified free cholesterol is secreted into intestinal lumen by ATP-binding cassette(ABC) transporters G5/G8(ABCG5/ABCG8).Transcription factor liver X receptor( LXR) plays an important role in the process of intestinal cholesterol absorption.The research progress in NPC1L1,ABCG5/ABCG8,ACAT2 and LXR is reviewed in this article.
5.Research on the Construction of Evaluation Index System for Physician Professionalism---Based on 8 Three-A Hospitals in Shanghai
Chinese Medical Ethics 2016;29(2):195-198
Objective:To inspect and improve physician professionalism effectively and preliminarily build eval-uation index system for physician professionalism. Methods:A sample of 240 physicians selected randomly from 8 Three-A hospitals in Shanghai were investigated using a self-designed questionnaire. Then the method of analyt-ic hierarchy process was performed in this study to construct the evaluation model of physician professionalism and determine every index weight. Results: An index system was initially built for physician professionalism evalua-tion. This system comprised three level-1 indexes namely moral quality characteristics, achievement action char-acteristics and vocational cognitive characteristics, as well as 14 level-2 indexes that drew from level-1 including responsibility etc. , at the same time determined their weight distribution. The judgment matrix had completely con-sistency through consistency check, indicating that the weight coefficient can reflect the relative importance of every index. Conclusion:Moral quality characteristics is one of the most important components of physician professional-ism evaluation; responsibility consciousness and vocational ideal are vital for the growth of physicians; lifelong learning and communication skills with high weight reflects needs of modern health care industry development;medical ethics consciousness has a trend of strengthening in physician groups, and enhancing evaluation index sys-tem for physician professionalism has the operability.
6.Risk factors of cholelithiasis in China:a Meta-analysis
Chinese Journal of Hepatobiliary Surgery 2016;22(6):386-390
Objective To investigate the risk factors of Gallstone Disease ( GD) by a meta-analy-sis, which hopefully will help to develop a strategy for its prevention .Methods Thirty case-control studies on risk factors of GD in Chinese patients reported from 1987 to 2014 were included .A quantitative compre-hensive analysis and a heterogeneity test were conducted and the OR value and its 95% confidence interval (CI) were calculated by using Stata 12.0.Results A family history of GD [OR(95%CI):2.73(2.22~3.35)], alcohol drinking [OR(95%CI):1.53(1.20~1.97)], a history of biliary tract roundworm [OR (95%CI):5.28(3.10 ~9.00)], a history of biliary tract infection [OR(95%CI): 28.50(19.22 ~42.26 ) ] , a BMI≥25 kg/m2 [ OR ( 95%CI ):1.70 ( 1.51~1.92 ) ] , greasy food intake [ OR ( 95%CI ):3.27(1.76~6.07)], a non-vegetarian diet [OR(95%CI):2.03(1.48~2.77)], hyperlipidemia [OR (95%CI):2.26(1.88~2.71)], menopause [OR(95%CI):3.25(2.49~4.24)] and multiple preg-nancies [OR(95%CI):1.56(1.29~1.88)] were risk factors of GD in China.Besides, milk drinking [OR(95%CI):0.43(0.34~0.55)] and regular breakfast [OR(95%CI):0.19(0.06~0.64)] were protective factors of GD.Tea drinking [OR(95%CI): 0.43(0.34 ~0.55)], smoking [OR(95%CI):0.86(0.51~1.45)], and a vegetarian diet [OR(95%CI):0.24(0.05~1.13)] were possible GD’s protective factors as they were not statistically significant .Conclusion Having breakfast , drinking milk , keeping fit , less alcohol and avoiding Ascaris infection prevent the occurrence of GD in China .
7.Soluble ST2 and its prospects of clinical application in cardiovascular disease
Chinese Journal of Laboratory Medicine 2014;37(12):969-972
Soluble ST2 (sST2) is a decoy receptor of IL-33 in blood.sST2and ST2L (receptor on cell membrane) seem to be markedly induced in mechanically overloaded cardiac myocytes,especially the expression of sST2.A large number of sST2 bind IL-33 thus subtracting IL-33 from the interaction with ST2L,potentially attenuating the cardioprotective effects of IL-33/ST2L pathway.Recently,sST2 has emerged as a novel for heart failure biomarker.Though sST2 was a less robust marker for the diagnosis of heart failure than NT-proBNP,it has been implicated in the prognostication of patients with acute dyspnea,acute or chronic heart failure and myocardial infarction,with particular value for mid-and long-term prognosis.However,further studies are needed in order to better point out the evidence for a routine use of sST2 evaluation in patients suffering from cardiovascular diseases.
8.Perioperative nursing of chest wall tumor removal and chest wall reconstruction
Chinese Journal of Practical Nursing 2015;(26):1971-1973
Objective To analyze perioperative nursing methods of chest wall tumor removal and chest wall reconstruction. Methods 12 patients with chest wall tumor removal and chest wall revascularization were choosed as the research objects,and which were given prospective nursing intervention combined with high quality nursing intervention. Results 12 patients all cured without one case death occurred, and 4 cases complications. Followed up for 6 to 36 months, no local recurrence of alienation, chest wall deformity and rejection. Conclusions Proactive nursing intervention help to predict perioperative complications. High-quality nursing care including psychological nursing, skin nursing, pain nursing, function training etc, can promote patients recovery.

10.The recent progress of bone coupling mechanism:function of bone marrow derived factors
Chinese Journal of Endocrinology and Metabolism 2017;33(2):156-158
Bone remodeling is an ordered process of coupling of bone resorption and bone formation. Cytokines secreted by different bone cells and membrane molecules expressed by bone cells are involved in regulation of coupling of bone resorption and bone formation. To reveal the mechanism of bone coupling is of great significance in the study and diagnosis of osteoporosis and other metabolic bone diseases. In the present review, we summarize the progression of mechanisms by which cytokines and the related membrane molecules are regulating the coupling of bone resorption and bone formation.
