Plague was classified as a natural focus disease,occurred in remote areas of tratfic block in the past.But with the development of society and economy,plague of long distance transmission risk is growing in the source regions and densely populated areas.In order to effectively prevent and control the spread of plague outbreaks are occurring,and long distance transmission spread in Qinghai Province,and adhere to the implementation of the long-distance transmission of plague prevention and control strategies,avoid threats and reduced long distance spread of plague.

Objective To explore the relationship between diethylhexylphthalate (DEHP) and peritoneal sclerosis and its possible mechanism. Methods Isolated human peritoneal mesothelial cells (HPMC) was cultured for five days in culture solution with varied doses of DEHP ７．７?of 10-6mol/L (A group), 5.4?１０－５mol/L (B group) and 2. 2?10-4 mol/L (C group) respectively. Culture solution without DEHP was as control. Total collagen synthesis and secretion was assayed by 3H-proline incorporation. ELISA method was used to detect the level of secreted fibronectin (FN) . The expression of FN mRNA , collagen ImRNA, collagen Ⅲ mRNA and TGF－?l mRNA was determined by RT-PCR. Results (1)HPMC expressed FN, laminin, collagen Ⅲ and TGF-?１. (2)DEHP stimulated FN and collagen expression with a higher level in C group compared with control(P

By integrating data of sci-tech novelty retrieaval and internet data,the paper makes a precise analysis of the potential demands,interest,interest,tendency,preferences and habits of users of novelty retrieval.From the perspective of big data technology,it analyzes the feasibility of designing targeted and deep-level services for mass user data,puts forward the framework and method of conducting deep-level and precise service recommendation based on users of sci-tech novelty retrieval,and studies the opportunity to provide these users with deep-level and precise services.

Serum Cholyglycine (CG)is a main component of human bile acid,one of the conjuga-ted bile acids formed by the combination of bile acid and glycine is synthesized in the liver cells.Glycochol-ic acid (CG)as a clinical indicator for detecting hepatobiliary disorders,and the traditional index of liver
function test compared has greater advantages,its detection for intrahepatic cholestasis,liver disease and biliary system diseases diagnosis,treatment and prognosis analysis of pregnancy to provide an important ba-sis.

Objective To evaluate the mutagenicity of hydrolysate of Meretrix meretrix Linnaeus soft tissue, so as to provide experimental basis for its exploitation.Methods Three mutagenicity tests were used to evaluate the mutagenic effects, including Ames test, CHL chromosome aberration assay and bone marrow micronucleus assay in mice.Results In Ames test, the revertant colonies numbers in each group were twice less than the numbers of spontaneous revertant colo-nies, five bacterial strains showed negative results with or without S9 activation, and the result of Ames test was negative. The CHL chromosome aberration assay and bone marrow micronucleus assay showed that the chromosome aberration rate and micronucleus rate of each dose group showed no significant difference compared with the negative control group, respec-tively ( P>0.05) .Conclusions Under this condition, the results show that all of the Ames test, chromosome aberration assay and bone marrow micronucleus assay are negative, and no mutagenicity is observed in the hydrolysate of Meretrix mer-etrix Linnaeus soft tissue.

Objective To exam the personality traits and self-concept of school phobia patients with different academic achievements.Methods 38 school phobia patients with high academic achievement and 19 school phobia patients with low academic achievement were assessed with Eysenck' s personality questionnaire and Piers-Harris Children' s Self-concept Scale.Results High academic achievement group of psychoticism and neuroticism higher than that of low academic achievement group.High academic achievement group of Self-concept's total scores,behavior,intelligence and the school situation higher than that of low academic achievement group.High academic achievement group of anxiety scale score lower than that of low academic achievement group.The personality traits of school phobia correlated with the self-concept on some level.Conclusion Different academic achievements of school phobia patients have different personality traits and have different self-concept,so they need to individualized treatment options.

Objective To investigate the relationship between the peak value of contrast media reaching abdominal aorta andpatients’ factors.Methods Ominpaque 300 mgI/ml 20 ml was injected at a rate of 2.5 ml/s in 108 patients and after 12 s was tracked by test bolus in the abdominal aorta at the level of celiac trunk, then the peak value in the abdominal aorta was achieved by the software dynamic evaluation. Regression analysis and stepwise regression analysis were used to study how the peak value of contrast media reaching abdominal aorta influenced by the patients’ factors including patients’ gender, age, height, weight, heart rate, blood pressure, injection site, peak time, and whether being with heart disease , diabetes mellitus or chemo . Results The peak value of contrast media reaching abdominal aorta was lower in male than that in female averagely, decreased gradually as the patients’ height, weight and peak time increased. The peak value of the injection site in the vein of hand back was lower than that of the cubitus generally and it was not influenced by the patients’ heart rate, blood pressure or whether being with heart disease, diabetes mellitus or chemo. Recommended formula of peak value(HU)=383.8400-Height(cm)?1.0909-Weight(kg)?0.6760+injection site?16.7878-peak time(s)?1.6882.Conclusion The volume of contrast media used in patients needing exam of CT angiography can be adjusted according to the patients’ age, gender, height, weight, injection site and peak time.

OBJECTIVE:To study the adverse drug reactions(ADRs)induced by weight-reducing drugs and to provide references for rational administration in clinics.METHODS:Classification statistic and analysis were conducted on462cases with weight-reducing drug-induced ADRs reported in62kinds of domestic and overseas medicinal periodicals published during the period of1980～2004.RESULTS:With pseudo-5-HTA appetite-suppressing drugs showing the high incidence of ADRs,which stood at36.36%of the total.Multi-systems were involved in ADRs,with the cardiovascular system showing the highest proportion(53.68%).The prognostic mortality accounted for18.61%of the total.CONCLUSION:ADRs induced by weight-reducing drugs were associated with many factors,to avoid the occurrences of which,medical workers should give more directions and monitoring on administration of drugs.
