Based on the introduction and analysis about PLoS One, and its number of published papers, impact fac-tor, publishing period, manuscript employed, publication fee, auditing, requirement for paper etc. , this paper pointed out break the barriers of traditional publishing model from several aspects, create a new way of open access scholarly pub-lishing, promoted the fast communication of scientific research. As the author of China, can choose more PLoS One pub-lished as our scientific research platform, improve our position in the field of scientific research in the world.

Classification,toxicity and determination method progress especially the pretreatment and limit of quantitation of beauvericin (BEA) and 4 main kinds of enniatins (ENNs) including enniatins A (ENA),enniatins A1 (ENA1),enniatins B (ENB) and enniatins B1 (ENB1) in food were introduced.The contamination levels of BEA,4 kinds of ENNs and their co-occurrence mycotoxins in food from Spain,Morocco,Italy,Japan and some other countries were analyzed.Establishment of high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) determination method for the complex food matrix was suggested.

Rabbit model of arteriosckrosis of iliac artery was used in this experiment. Results showed: after 4 weeks of PTA operation, the calibre of the artery in large dose concentrated pill (LCP) group was obviously larger than that of the western drug group and Lovastatin group (P

Objective To investigate the life quality changes and influencing factors of acute coronary syn -drome after stent implantation .Methods 100 cases with acute coronary syndrome received stent implantation were selected .SF-36 life quality questionnaire was used to survey the patients′life quality before operation and 6 months af-ter operation,and the life quality changes and influence factors were analyzed .Results 6 months after operation,the physical activity ,mental health ,social activities ,physical pain ,physical function ,physical role ,energy and health score of the patients were higher than before operation (P<0.05).According to Logistic regression analysis ,female,type 2 diabetes,underwent percutaneous coronary intervention ,ST-T segment elevation myocardial infarction were the im-portant factors affecting patients′recovery(P<0.05).Conclusion 6 months after stent implantation,the life quality of the patients with acute coronary syndrome were improved obviously;the female and underwent percutaneous coro-nary intervention have positive influence on patients′recovery,while type 2 diabetes,ST-T segment elevation myocar-dial infarction affect patients′recovery in negative way .

Objective To assess the influence of community and hospital comprehensive Health management on quality of life in aged patients with coronary artery disease (CAD) after PCI.Methods 147 patients with CAD after PCI were divided into experimental group(72 cases) and control group (75 cases) accordance with their residential community.In control group,community health education was introduced.While in experimental group,hospital and community comprehensive healthy education lasted for one year.Before and after invention,major adverse cardiac events (MACE) was recorded and generic quality of life inventory (CQOLI-74),self-rating anxiety scale (SAS),and self-rating depression scale (SDS) were carried out on the basis of giving unite guiding words.Results The observation items of the SAS(34±6 vs41 ±7,t =2.714,P ＜0.01)and SDS(35 ±7 vs 41 ±8,t =2.572,P ＜0.05)scores in experimental group were lower than those in control group.Meanwhile the body health dimension(63 ± 12 vs 59 ±11,t =5.935,P ＜0.01 ),psychological health dimension(64 ± 14 vs 58 ± 13,t =6.116,P ＜0.01 ),social function dimension(64 ± 11 vs 58 ± 10,t =6.157,P ＜0.01 ) were higher than those in control group,but the difference of the material life dimension and the MACE rate were not statistically significant( P ＞0.05).Conclusions Community and Hospital comprehensive health management is a practical and valuable strategy for palliating the depression and anxiety and improving quality of life after PCI in aged patients.

OBJECTIVE To investigate the antibiotic use during perioperative period in surgery after administration according to Antibiotic Drug Use Guideline.METHODS The antibiotics usage status among 462 outpatient cases in Mar 2005 and 483 cases in Mar 2006 during perioperative period in surgery were surveyed.RESULTS The preventive use rate of antibiotic medication in surgery in 2005 and 2006 were respectively 99.48% and 88.12%(P

Objective To observe the effect of drug pairs of extracts from Rhizoma Chuanxiong(RC)and Radix Paeoniae Rubra(RPR)in different proportions on promoting blood circulation and removing blood stasis in rats and to find the optimal proportion between the two extracts.Methods The Wistar rat models of blood stasis were established by injection of adrenalin.The changes of the platelet aggregation and adhesiveness and erythrocyte aggregation were observed.Results Blood vessel contraction increased,the platelet aggregation and erythrocyte aggregation increased,erythrocyte deformation occurred and the blood viscosity increased in the model rats.The drug pairs could reduce blood viscosity,ameliorate erythrocyte ability of deformation,reduce erythrocyte aggregation and inhibit platelet aggregation.The effects were obvious especially in the groups of RC and RPR in the proportions of 0.45 g to 0.45 g,0.21 g to 0.45 g.Conclusion The drug couples from RC and RPR in different proportions could improve the blood rheology,the effect being obvious in the groups of RC and RPR in the proportions of 0.45 g to 0.45 g,0.21 g to 0.45 g.

OBJECTIVE To offer scientific basis for reasonable usage and management of antibiotics through surveying the situation and problems of antibiotics usage in surgery during perioperative period.METHODS The antibiotics usage status among 462 cases of patients during perioperative period was retrospectively analyzed.RESULTS Antibiotics were used in 460 patients.The rate of prophylactic usage was 83.26%,the rate of therapeutic one was 16.74%;the duration of postoperative prophylaxis was:80.68% of the patients were treated with antibiotics for 4 days or more,the longest one was 28 days;43.26% of the patients received single antibiotic treatment,and 44.13%,11.96%,or 0.65% of patients received 2,3 or 4 kinds of antibiotics combined therapy respectively.CONCLUSIONS Improper application of antibiotics during perioperative period needs higher level administration.

OBJECTIVE To investigate the risk factors of professional exposure among medical staff and explore the preventive strategies.METHODS The influence of factors including profession,exposure process,exposed materials,treatment process,and follow-up among 110 medical staff with professional exposure was analyzed.RESULTS The general incidence of professional exposure was 52.73%,35.45% and 6.36% for clinical doctors,nures,and workers,respectively.Among all exposure cases,we found the incidence was 62.73% for pricking wound,20% for various liquid contamination,4.55% for glass injury,2.73% for scalpel cutting,and 4.55% for other instrument related damage.The reasons leading to exposure were treatment and nursing care,surgery assistance,and instrument and materials manipulation,which accounted for 40%,31.82%,and 18.18% of total incidence,respectively.All of the exposure cases had been properly treated.None of the investigated cases had been found illed with blood derived transmitted disease caused by professional exposure.CONCLUSIONS It is critical to intensify the training of medical staff for the knowledge of professional exposure and to improve their personal protective awareness,so that the incidence of professional exposure could be reduced.
