Objective To study the probability of evaluating myocardial tissue perfusion by corrected TIMI frame count (CTFC) after successful percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods Sixty-three patients with their first acute myocardial infarction (AMI) who accepted primary coronary intervention were recruited. All these patients got TIMI 3 grade flow. CTFC was measured after successful PCI in these patients. Wall Motion Score Index (WMSI) assessed by two-dimensional echocardiography before and one month after PCI and the correlation studied between CTFC and WMSI. Results According to CTFC the patients were divided into two groups. Improvement of WMSI in the TIMI 3 fast group was significantly greater than that of the TIMI 3 slow group. CTFC had a significant correlation with the change in WMSI. Elapsed time from the onset of symptoms to reperfusion in the TIMI slow group was significantly longer than that of the TIMI fast group. Conclusion CTFC is a quantitative, and reproducible index of coronary blood flow. Lower CTFC is associated with greater functional recovery and could supply evidence for additional adjunctive treatment.

The paper presented in focus the development from multiple social medical insurance funds to a universal social medical insurance system in South Korea, and analyzed those serious setbacks including monopolizing private medical organizations, lack of first-visit and referral system, and excessive percentage of personal payment, as a result of unparallel progress of the reform of medical insurance and that of healthcare system. Authors hope to be inspirational for the ongoing reforms in the social medical insurance system and healthcare system, in an effort to avoid likewise mistakes.

Objective:To observe the effect of “One Coat Bond” on the interface between amalgam restoration and cavity wall used in bonded amalgam restoration(BAR).Methods:Dentin cavities were made on 15 healthy human premolars extracted for orthodontics therapy.The teeth were divided into 3 groups with 5 in each group.In group A compressive air was used to dry the cavities(dry adhesion) whereas in group B absorbent cotton was used (wet adhesion). Then the cavity walls in the two groups were treated with the “One Coat Bond”, the cavities were filled with freshly prepared amalgam before adhesive concrete.In group C cavities were filled directly with amalgam without treatment of cavity walls. Morphology of amalgam restoration/“One Coat Bond” adhesive/dentin cavity wall interface was observed under SEM, thickness of adhesive and width of space between amalgam restoration and cavity wall was measured. Results:Average width(?m) of space between restoration and cavity wall was 4.82 in group A, 0 in group B and 11.33 in group C(P0.05).Conclusion:“One Coat Bond” adhesive can significantly improve the compactness between amalgam and cavity wall.

Objective To discuss the major cardiovascular disease(CVD) risk factors and volume load of women.Methods A cross-sectional study was conducted on adult women who came to our hospital for health examination.The clinical data included age, past medical history, smoking history, drinking history, body measurements (height, body weight, blood pressure, etc.), and blood serum creatinine, hemoglobin, blood glucose, blood lipid and other biochemical indicators were detected.Using the human body composition analyzer, the extracellular fluid (ECW), intracellular fluid (ICW), total water(TBW), and ECW/TBW ratio (E/T) were used to evaluate the capacity of the cells.Total body water(TBWwatson) was Calculated according to Watson formula.The clustering of four major CVD risk factors (defined as two or more of the following: hypertension, diabetes, dyslipidemia and overweight) and their association with volume load were investigated.Volume load was evaluated by bioelectrical impedance analysis.Hypovolaemia was defined as extracellular water/total body water (ECW/TBW) at and under the 10 percentile for the normal population.Logistic regression model was use to explore the relationship between capacity status and risk factors of CVD.Results A total of 2 433 women (mean age (37.4±7.3) years old) were enrolled in the study, 14.7％ of them had clustering of CVD risk factors.Hypovolaemia in clustering group was statistically higher than either in the single or in the none risk factor group, which was 18.2％, 11.9％, 6.7％, respectively (x2 =45.4, P＜0.001).After adjusted for potential confounders (including age, hemoglobin, serum uric acid, estimating glomerular filtration rate (eGFR), hypovolaemia was associated with clustering of CVD risk factors, with an OR of 2.76 (95％ CI 1.93-3.95).Conclusion Hypovolaemia is associated with clustering of major CVD risk factors in women, which further confirms the importance of modifying lifestyle to reduce the burden of CVD.

Many provinces are carrying on Public Hospital Personnel Filing System Reform while facing a series of barriers cause a slow progress or the results not up to expectations.Supporting policies' adjustment is called to ensure the smooth progress of the reform.

Vascular endothelial growth factor (VEGF),platelet derived growth factor (PDGF) and complements play key roles in the pathogenesis of age-related macular degeneration (AMD).Pegaptanib,the first therapeutic aptamer against VEGF165,has been approved by the Food and Drug Administration (FDA) of US for the treatment of exudative AMD.Another two aptamers El0030 and ARC1905,each target PDGF-B and complement C5 respectively,are undergoing clinical trials.Recent trends to treat AMD are combined therapies targeting multiple key molecules in the pathogenesis of AMD;aptamers against multiple targets may become the preferred drug for AMD.

Objective To analyze the correlation between liver tissue hypoxia inducible factor‐1α(HIF‐1α) protein expression and multidrug resistance protein (MRP) expression between .Methods Our hospital from March 2012 to March 2013 the Depart‐ment of Pathology of the liver paraffin‐embedded specimens of a total of 83 cases of specimen processing ,production of tissue sec‐tions ,HIF‐1αexpression was observed ,the positive expression of MRP .Results 83 cases of specimens in HIF‐1α 50 cases were positive ,the positive rate was 60 .2% ;of which the well‐differentiated tumor samples of HIF‐1α positive rate was 74 .1% ,signifi‐cantly higher than the 28 .0% poorly differentiated (P<0 .05);and the absence of lymph node metastasis positive rate of HIF‐1αwas no significant difference (P>0 .05) .In 83 cases of samples ,58 samples were MRP positive ,the positive rate was 70 .0% ;MRP positive rate among the high degree of 77 .6% ,significantly higher than the 52 .0% poorly differentiated (P<0 .05);and lymph node tumors MRP positive rate of metastasis were 76 .30 ,64 .4% respectively ,the difference was not statistically significant (P>0 .05) .MRP expression in the same samples were positive ,the HIF‐1α expression was also significantly increased .Conclusion HCC HIF‐1αprotein expression and MRP expression has some relevance .

International experiences can provide evidences for general practitioners ( GPs) system building in China. The paper reviews the development of GP systems from several typical countries of different insurance sys-tems, including national health care systems, commercial medical insurance systems, and social medical insurance systems, etc. The factors that influence GPs systems are analyzed. It is found that the control force of health security system on health system, the control force of specialists on health system, the incentive mechanism of general prac-tice, and the development of general medicine influence the establishment of GPs systems. Finally, this paper pro-vide several policy implications:First, in order to meet the needs of public health, a GPs system with Chinese char-acteristics should be established;Second, the core values of general medicine should be promoted to provide public support for the establishment of a GPs system;Third, a sound incentive mechanism should be established for the de-velopment of a GPs system to improve the status of general practitioners;Fourth, the division of general practitioners and specialists should be promoted to improve the development of general medicine.
