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.

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.

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.

BACKGROUND: PI3K is a family of enzymes involved in insulin signal transductlon pathway, the abnormal expression of which would affect synthesis, secretion, and migration of GLUT4, therefore, results In increased blood sugar, eventually, leads to diabetes.OBJECTIVE: To discuss the effects of insulin combined with selenium on PI3K and GLUT4 expression in cellular signal transduction of skeletal musde in diabetic rats.METHODS: Sprague Dawley (SD) rats were randomly divided into the control, diabetic, insulin-treated diabetic, selenium-treated diabetic and combination administration groups. All rats were prepared for diabetic models by injecting 50 mg/kg Streptozocin exception of the control group. Rats in the control and diabetic groups ware free to food and water; in the insulin treatment group,rats were subcutaneous injected 1 U/(kg·d) insulin. Rats in the selenium treatment group ware treated with a dose of 180 pg/kg per day of sodium selenite dissolved in redistilled water by gavage; and in the combination administration were given both treatments for 4 successive weeks. The levels PI3K end GLUT4 in skeletal muscle were estimated using Western blotting and immunohistochemistry techniques.RESULTS AND CONCLUSION: Immunohietochemistral results were accordance to Western blotting results, which showed the combination of insulin and selenium can remarkable Increase the levels of PI3K in skeletal muscle and GLUT4 in skeletal muscle membrane fraction, therefore, enhance the insulin signal transduction pathway.

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 .

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.

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.
