Objective To explore the predictive value of combined measurement of D-dimer (D-D),fibrinogen (FIB),and peripheral blood leukocyte count (PBLC) for the severity of acute pancreatitis (AP).Methods We collected the clinical data of 134 hospitalized patients who were diagnosed with AP in the General Hospital of Ningxia Medical University from January 2014 to January 2016.These patients were divided into mild acute pancreatitis (MAP) group (n =72) and severe acute pancreatitis (SAP) group (n =62).Also,these patients were divided into hyperlipidemic acute pancreatitis (HAP) group (n =43) and biliogenic acute pancreatitis (BAP) group (n =91).The initial measurements of D-D,FIB,and PBLC for the patients who were admitted to the hospital within 24 hours of onset and received no treatment before admission were collected.The t test was used for comparison of normally distributed continuous data,while the Mann-Whitney U test was used for non-normally distributed continuous data.The chi-square test was used for comparison of categorical data.In addition,the Spearman correlation test and Pearson correlation test were used for correlation analyses.The receiver operating characteristic (ROC) curve was used to analyze the predictive values of D-D,FIB,and PBLC for the severity of AP.Results Compared with the MAP group,the SAP group had significantly increased D-D and FIB levels in peripheral blood (Z =-3.171,P =0.002;t =-2.339,P =0.021).Compared with the HAP group,the BAP group had a significantly higher D-D level (Z =-4.178,P ＜ 0.001),an insignificantly higher FIB level (P ＞ 0.05),and a significantly lower PBLC (t =2.466,P =0.015).The areas under the ROC curve (AUCs) of D-D,FIB,and PBLC were 0.659,0.611,and 0.591,respectively,and D-D had a higher value than FIB and PBLC in predicting the severity of SAP.The AUC of a combination of D-D,FIB,and PBLC was 0.712.Plasma D-D and FIB levels were positively correlated with the severity of AP (r =0.275 and 0.192,P =0.001 and 0.026).Conclusions D-D,FIB,and PBLC are important for early judgment of the severity of AP,and a combination of the three markers has greater significance.

Objective:To establish a preliminary diagnostic criteria of pathological internet use for field test in China.Methods:Through searching common "pathological internet use" diagnostic criteria or screen criteria in literature,a diagnostic criteria items pool and a preliminary diagnostic criteria of "pathological internet use" were established .According to the diagnostic criteria,each 2 senior professional psychiatrists in turn interviewed 79 patients and their parents,and then made diagnosis respectively. In addiction,44 high school students were each evaluated by one psychiatrist.The definite diagnosis was made when 2 evaluators make the same diagnosis for one patient.Result:In 123 patients,54 were pathological internet use.For diagnosis,the value of kappa for inter-rater reliability was 0.812( P<0.001).In the 12 criteria items,2 for poor inter-rater reliability and 4 for little contribution to diagnosis were eliminated.In the reserved 6 items,if 4 items(or more)were positive,the diagnostic sensitivity was 78.9% and specificity was 95.3%.Functional impairment criteria were made strictly.In the patients who were made the definite diagnosis,90.7% had duration of illness above 3 months,and 77.7% above 6 months.Conclusion:The preliminary diagnostic criteria of pathological internet use after revised includes 6 symptom criteria,3 functional impairment criteria,duration of illness and exclusive criteria.The criteria proposed is with high consistency on evaluations made by psychiatric raters,and with operational convenience.The criteria,after further revised,may fit the clinical application.

Outbreaks of pseudorabies (PR) have occurred in southern China since late 2011, resulting in significant economic impacts on the swine industry. To identify the cause of PR outbreaks, especially among vaccinated pigs, 11 pseudorabies virus (PRV) field strains were isolated from Guangdong province during 2013–2014. Their major viral genes (gE, TK, gI, PK, gD, 11K, and 28K) were analyzed in this study. Insertions or deletions were observed in gD, gE, gI and PK genes compared with other PRV isolates from all over the world. Furthermore, sequence alignment showed that insertions in gD and gE were unique molecular characteristics of the new prevalent PRV strains in China. Phylogenetic analysis showed that our isolates were clustered in an independent branch together with other strains isolated from China in recent years, and that they showed a closer genetic relationship with earlier isolates from Asia. Our results suggest that these isolates are novel PRV variants with unique molecular signatures.

The aim of this study was to develop a semi-quantitative immunochromatographic method for rapid detection of Newcastle disease virus (NDV) antibodies by expressing HN protein in rice endosperm bioreactor. The recombinant plasmid pUC57-HN was digested by MlyⅠ and XhoⅠ to retrieve the HN gene, while the intermediate vector pMP3 containing promoter, signal peptide and terminator was digested by NaeⅠ and XhoⅠ. The HN gene and the linearized pMP3 were purified and ligated to form a recombinant plasmid pMP3-HN1. Subsequently, pMP3-HN1 and plant vector pCAMBIA1300 were digested by EcoRⅠ and Hind Ⅲ, and the HN1 gene was cloned into pCAMBIA1300. The recombinant plasmid pCAMBIA1300-HN1 was introduced into Agrobacterium tumefaciens EHA105 by electrotransformation, and the pCAMBIA1300-HN1 was transferred into rice callus by agrobacterium-mediated method. After dark culture, callus screening, differentiation, rooting and transplanting, transgenic rice seeds were obtained 4 months later. PCR identified that the HN gene has been inserted into the rice genome. SDS-PAGE and Western blotting indicated that the HN protein was successfully expressed in the positive rice endosperm. The purity of the HN protein was more than 90% by SP cation exchange chromatography and gel filtration chromatography. According to the national standards for the diagnostic techniques of Newcastle disease HI test (HI≥4log₂, positive antibody reaction), a colloidal gold labeled purified HN protein was used to prepare a semi-quantitative test strip by double-antibody sandwich method for rapid detection of NDV antibody. The results showed that the test strip did not cross-react with positive sera against other viruses, and the sensitivity of the test strip reached 1:102 400 for standard positive sera of Newcastle disease. Testing of a total of 308 clinical sera showed that the compliance rate of the test strip with HI test was 97.08%, and the Kappa value was 0.942. In conclusion, high purity recombinant HN protein was obtained from rice endosperm, and a simple, rapid, highly sensitive and highly specific semi-quantitative immunochromatographic strip was developed. The test strip could be used for immune evaluation of the Newcastle disease vaccine.
