Objective To investigate different scoring systems in predicting the severity of acute pancreatitis(AP).Methods The clinical data of 1 56 patients with AP were retrospectively reviewed.Ser-um c-reactive protein(CRP)levels were measuredat admission.According to the Chinese guidelines for the management of acute pancreatitis(2007),all the patients were categorizedas either mild acute pancre-atitis(MAP)or severe acute pancreatitis(SAP).Ranson,acute physiology and chronic health evaluation (APACHE)-Ⅱ,bedside index for severity in acute pancreatitis(BISAP),and computed tomography se-verity index(CTSI)scoring systemswere calculated according to the corresponding grading standardsin all patients.Patients were divided into MAP group(APACHEⅡ <8,Ranson <3,BISAP <2,CTSI <3 and CRP <21 .4)and SAP group (APACHEⅡ≥8,Ranson≥3,BISAP≥2,CTSI≥3 and CRP≥21 .4)ac-cording to the scoring results.ROC curve was used to compare the difference among the systems.Results Among the 1 56 patients,21 (1 3.5%)were classified as SAP and 1 35 as (86.5%)MAP.AUCs for Ranson,BISAP,APACHEⅡ,CTSI,and CRP in predicting SAP were 0.69 (95%CI:0.62-0.76),0.74 (95%CI:0.66-0.80),0.78 (95%CI:0.70-0.84),0.69 (95%CI:0.61 -0.76),and 0.68 (95%CI:0.57-0.78),respectively.There were no significant differences among these scoring systems.Conclusion There were no significant differencesin predicting the severity of AP among these scoring systems. Therefore,the early prediction of SAP should consider multiple scoring systems,and the referential signifi-cance of accessing and applying a simpler laboratory indicator deserves further studies.

With the development of the food industry in China,it has been found that food safety is becoming the biggest issue in the food manufacture and logistics. Accurate and timely to establish a risk assessment method in produce market is the challenge for food safety system. Predictive microbiology is a core early warning technology in the food safety risk assessment. According to the microorganism predicting model,the pathogen and spoilage microorganism's growth in food can be fast judgment in advance. And it plays an important part in controlling the growth of pathogen and the spoilage microorganism in food. This paper summarized the predictive microbiology model's establishment and the present research situation,and discussed the present situation and application of predictive microbiology in food safety risk assessment. The future trend of predictive microbiology in food safety risk assessment was prospected as well.

In recent years, the studies of the treatment of cerebral infarction have turned to the areas of neuroprotective agents. The promotion of angiogenesis after stroke will become one of the novel approaches after cerebral infarction. Studies have shown that the activation of the kallikrein-kinin system (KKS) after cerebral infarction may promote angiogenesis after cerebral infarction, improve the neurological deficits, and reduce the mortality and disability. This article reviews the regulatory mechanisms of KKS in the angiogenesis after cerebral infarction.

Objective To explore the clinical characteristics and treatment of paroxysmal supraventricular tachycardia (PSVT) in children. Methods The clinical data of 67 children with PSVT were analyzed retrospectively, and the therapeutic effects of different treatments were compared. Results The clinical manifestations of infants were paleness, shortness of breath, irritability and sweating, and children showed chest tightness, palpitations, abdominal discomfort and fatigue. The curative effect of electric cardioversion, transesophageal atrial pacing, physical therapy, and drug therapy was statistically different (P<0.05), The different cardioversion rates of them were observed for the treatment of paroxysmal supraventricular tachycardia. The cardioversion rate of transesophageal atrial pacing, was the highest, and the rate of physical therapy was the lowest. There was no significant difference in the cardioversion rate between propafenone, digoxin and amiodarone. Conclusion The clinical manifestations of PSVT in infants are atypical and easily to be ignored. There are many methods for treatment of PSVT. The vagus nerve can be stimulated first, and, if no response, either drugs or electric cardioversion and transesophageal atrial pacing can be used. The cardioversion rate of transesophageal atrial pacing is higher. The drug effectiveness for the treatment of PSVT depends on many factors, and our choice of medication varies from person to person.

Objective To explore the reliability and validity of the Chinese version of driver stress inventory (DSI). Methods Three hundred drivers were investigated with DSI. The structure validity,content validity and internal reliability were examined. Results (1)Except items 9,16 and 18, the others had good discrimination. (2) Six factors were extracted which could explained 45.277% of the total variance. The six factors were significantly correlated with DSI total score(r = 0.241～0.622, P<0.01). (3)The spilt-half reliability was 0.557, The six factors ' Cronbach alphas were 0. 569, 0. 631, 0. 799, 0. 675, 0. 587 and 0. 685 respectively. ConclusionDSI has good reliability and validity, and is an effective instrument to test drivers' stress.
