Syncope is a common clinical problem in children and adolescents. It is a major challenge for practicing physicians, and medical resource utilization and expenses associated with syncope management are enormous. A diagnostic protocol to syncope must be developed for children and adolescents for convenient and effective final diagnosis, and an analysis of cost-effectiveness is meaningful. Thus, according to the studies of syncope in children in China,the Chinese Pediatric Cardiology Society proposed the guidelines for diagnosis of syncope in children in China, and developed a simplified diagnostic protocol for children and adolescents with syncope. According to a multi-center prospective study,the diagnostic protocol in children and adolescents with syncope results in an improvement of diagnostic yield.

Young faculty are an essential part of a university's strength and is important for its sustainable development.And their scientific research capability is associated with the long-term development of the university.At present,there are 4 major problems with the development of young faculty's research capabilities,which include their relatively single academic knowledge structure,insufficient experience in writing proposals,insufficient opportunities for academic exchange,and inequity in resource allocation.Establishing a training mechanism may help solve some of the problems and promot their development.The research management department of a university must abandon erroneous traditional management concepts,provide research training seminars,develop a new mechanism to stimulate academic exchange,design a system for short-term laboratory rotations,and promote the participation of your faculty in major research projects.These may bring about marked improvement in the improvement of young faculty's research capabilities.

BACKGROUND: Several studies have demonstrated that degradable polycaprolactone film has no apparent influences on cellular immune function of rat critical organs including heart, liver, and kidney, and possesses the prerequisite of anti-adhesion formation.OBJECTIVE: To investigate the role of degradable polycaprolactone film in preventing rat peritoneal adhesion following surgery.DESIGN, TIME AND SETTING: The present randomized, controlled animal experiment was performed at the Department of Physiology, Jilin University.MATERIALS: A total of 120 male Wistar rats, weighing 180-220 g, were included in this study. Peritoneal adhesion was induced in all rats. Non-bio-degradable film was sourced from Wuhan Boster Company, China. Polycaprolactone film was purchased from U.C.C Company. England.METHODS: All 120 rats were randomly divided into 3 groups, with 40 rats per group: control, non-bio-degradable film, and polycaprolactone film. Peritoneal adhesion was induced in all rats. The non-bio-degradahle film and polycaprolactone film groups were subjected to peritoneal wound cover with non-bio-degradable film and polycaprolactone film, respectively. From day 1 following surgery, each rat daily received an intraperitoneal injection of 4 mL 2 g/L pseudomonas enzyme, for a total of 3 successive days.MAIN OUTCOME MEASURES: At 1, 3, 7, and 30 days following surgery, 10 rats were selected from each group for observation of peritoneal adhesion.RESULTS: Totally 120 rats were included in the result analysis. Peritoneal adhesion was successfully induced in rats from the control group. From day 7 following surgery, the peritoneal adhesion rate was significantly lower in the polycaprolactone film group than in the control group (P<0.01). In the non-bio-degradable film group, the peritoneal adhesion rate exhibited decreasing followed by increasing tendency; by day 30, the adhesion rate was significantly higher compared to the polycaprolactone film group (P<0.01).CONCLUSION: Polycaprolactone film is degraded by pseudomonas enzyme to avoid the new adhesion caused by foreign stimulation.

The microRNAs is a kind of endogenous and non-coding small RNA ,which possesses biological function negatively regulating gene expression.Recent researches also found that artificial controlling some microRNAs ex-pressions can improve heart function via regulating skeletal myoblasts through multiple mechanisms,so may become a new breakthrough point in myocardial infarction treatment area.

Background and purpose:Actin related protein 2/3 complex subunit 5 (ARPC5) is involved in the packaging of actin, and then affects the mobility of cells. It plays an important role in the formation of invadopodia of cancer cells. This study aimed to investigate the effect of ARPC5 gene-silence on cell proliferation, migration and invasion of lung squamous carcinoma cell line SK-MES-1. Methods:Under the induction of LipofectamineTM RNAiMAX, the recombinant of si-ARPC5 was transfected into SK-MES-1. The experiment set up 3 groups:blank (mock) group, negative control (NC) group and si-ARPC5 transfected group. Cell proliferation, migration and invasion assays were investigated by cell counting kit(CCK-8) method, scratch assay and Transwell Chambers respectively. Results:The result of qRT-PCR and Western blot displayed downregulation of ARPC5 in mRNA and protein level of SK-MES-1 cell. Proliferation rate of SK-MES-1 cells in 72 h after si-ARPC5 transfection was lower than those in mock and NC groups (t=7.993, t=8.681, P<0.05). Compared to the mock and NC groups, the scratch repairing rate of the si-ARPC5 group was lower [(43.32±0.23)%vs (73.11±0.43)%and (76.58±0.88)%] (t=7.348, t=10.614, P<0.05);And the number of penetrating the membrane was signiifcantly reduced [(27±6) vs (101±11) and (92±9)] (t=10.229, t=8.391,P<0.05). Conclusion:Downregulation of ARPC5 gene can inhibit the proliferation, migration, and invasion of SK-MES-1 cell.

Macrophages are important immunocytes in human body , playing an important role in antigen and inflammation process.In recent years , it has shown that macrophage is a kind of cell mass with high plasticity , heterogeneity , diverse and variable immune functions .They can be polarized into different phenotypes in different microenvironments or stimulations , playing different roles in the process of inflammation .There are a variety of factors which can modulate macrophage polarization process , such as the de-velopment and progression of metabolic diseases .The polarization of adipose tissue macrophages and the factors in the regulation of macrophage polarization are summarized in this paper .

Myocarditis is one of the most common acquired heart diseases in children,and one of the most common causes of a pediatric dilated cardiomyopathy phenotype.The myocarditis is a difficult issue in the diagnosis and the optimal means of therapy.A recent Pediatric Cardiomyopathy Registry (PCMR) analysis in the largest group of pediatric myocarditis patients ever studied confirmed that the most common outcome in pediatric myocarditis was cardiac recovery,but approximately 30％ of pediatric myocarditis patients would die or undergo heart transplantation.Animal studies and adult experience suggested that autoimmunity might contribute to cardiac dysfunction in myocarditis.Immunosuppressive and immunomodulating therapy for pediatric myocarditis remains controversial.Small case series have shown benefit of these therapies in pediatric myocarditis.A limited number of biomarkers associated both good (recovery) and poor (death or transplantation) outcomes could be identified.We should do our best to find these biomarkers in the future.

Objective To explore the effective countermeasures for the Scientific research funds auditing in medical schools.Methods Political-Economic-Social Technological (PEST) method was used to analyze the macro environment changes for research funding audit,including policy,economics,social,technology..We described the situation in the research funds auditing,based on the model of Strengths-Weaknesses Opportunities-Threats (SWOT).Results Some counter-measures in the research funds auditing are recommeded for solution.Conclusions The PEST-SWOT model could provide effective countermeasures for the research funds auditing in medical schools.
