Objective To investigate the change of peripheral blood CD4+CD25+ regulatory T cells (Tr) in patients with idiopathic thrombocytopenic purpura (ITP), and to analyze its role in the pathogenesis of ITP.Methods Anticoagulated venous blood was collected from ITP patients (ITP group,n=35) and healthy controls (healthy control group,n=35). T lymphocytes were isolated and purified with human CD3+ T cell enrichment columm. The percentage of peripheral blood CD4+CD25+ regulatory T cells was detected by immunofluorescence staining (PE-anti-CD4 monoclone antibody and FITC-CD25 monoclone antibody) and bicolor flow cytometry by CD25/CD4 gating.Results The number and constituent ratio of CD4+CD25+T cell were significantly lower in ITP group than those of healthy control group (P<0.05).Conclusion There is peripheral blood celluar immunological function disorder in ITP patients, and decrease of CD4+CD25+ T cell population may be involved in the pathogenesis of ITP.

Clinic expert information provides important references for residents in need of hospital care. Usually, such information is hidden in the deep web and cannot be directly indexed by search engines. To extract clinic expert information from the deep web, the first challenge is to make a judgment on forms. This paper proposes a novel method based on a domain model, which is a tree structure constructed by the attributes of search interfaces. With this model, search interfaces can be classified to a domain and filled in with domain keywords. Another challenge is to extract information from the returned web pages indexed by search interfaces. To filter the noise information on a web page, a block importance model is proposed. The experiment results indicated that the domain model yielded a precision 10.83% higher than that of the rule-based method, whereas the block importance model yielded an F₁ measure 10.5% higher than that of the XPath method.

Objective: To test the feasibility of drag-reducing polymers (DRP) for improving coronary microcirculation in a canine model in order to provide the experimental basis for treating myocardial microcirculation dysfunction. Methods: A total of 8 dogs received open-chest surgery and they had intravenous injections, in turn, with adenosine (ADN), DRP 250 mg/L and DRP+ADN. The function y=A × (1-e-βt) was used to calculate the myocardium capillary volume (A value), capillary velocity (β value) and myocardial blood lfow (A ? β value) by myocardial contrast echocardiography. Results: With DRP infusion, the A value in experimental canine was similar to the baseline condition,P>0.05; while theβ value and A ? β value were signiifcantly increased as (0.57 ± 0.10) 1/s vs (0.23 ± 0.03) 1/s,P<0.01 and (11.51 ± 1.96) VI/s vs (5.15 ± 0.86) VI/s,P <0.05 respectively. With combined infusion of DRP+ADN, the β value and A ? β value were similar to the baseline condition, bothP>0.05. Conclusion: DRP improved coronary microcirculation primarily by modulating the β value in experimental canine model, and hopefully, this unique hemodynamics could provide a new approach for treating myocardial microcirculation dysfunction.

The scientificalness of page quality assessment was improved by adding the page vote fraction and the user satisfaction with page according to the time perception-based PageRank Algorithm. The individualized retrieval was realized by adding the users-interested model that was matched with page types and by moving up the users-interested page rank.
