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.

By using the software CiteSpace Ⅱ,the paper makes a quantitative analysis and interpretation of research literatures on telemedicine in SCIE of Web of Science from three perspectives,namely the research hotspots,knowledge base and research fronts.The research hotspots of telemedicine mainly include tele-diagnosis,tele-monitoring and evaluation of the application effects of telemedicine.It sets forth key literatures representing the knowledge base one by one and reveals that most of them focus on clinical applications.The analysis of burst terms indicates that more attention has been paid to tele-monitoring and distance education of chronic diseases in recent years and mobile technology is one of the greatest driving forces for the development of telemedicine at the present stage.

The gap between foreign and domestic medical and health information construction levels was described and the major factors that influence the domestic medical and health information construction level were analyzed by analyzing the medical and health information construction levels in USA, Britain, Canada, Germany, Japan, Aus-tralia and China according to the input-output data in WIOD, with suggestions put forward for the improvement of domestic medical and health information construction.

Alcohol-infusion. Conclusion: With the cell-wall-broken extraction process, a higher content of total flavones was obtained from Pollen Typhae .

Objective Dissolution test was applied to study the dissolution rates of total flav ones from Pollen Typhae before and after wall breaking.Methods The content of total flavones was determined by UV -spectrophotometry an d Basket -Stirring Method.Results Using total flavones as the index,T 50 was 29.57min and T d was 41.28min before wall break-ing,and 41.27min and 54.26min respectively after wall breaking,the dif ference being very significant.Conclusion The dissolution rate of the total fla vones from Pollen Typhae is faster after wall -breaking treatment than th at before treat-ment.

Chronic inflammatory response often involves in the progression of disease in all organ system.While inflammation has been a highlight topic of study in many decades for patho-genesis or identifying drug targets to disease-associated inflam-mation.In this paper,the main fundamental research areas of projects funded by NSFC on inflammation during 2010 ~2015 are reviewed.The features and research types of projects are an-alyzed.

ObjectiveTo investigate the recent treatment result and the toxic responses of chemoradiotherapy with lobaplatin and paclitaxel in advanced esophageal carcinoma. MethodsFrom April 2010 to May 2011, 26 initial treatment patients withadvanced esophageal carcinoma were enrolled. The chemotherapy consisted of paclitaxel (135 mg/m2) on day 1 and lobaplatin (35 mg/m2) on day 2,and one cycle continued 21 days. Radiotherapy started on the second day after the fist cycle of chemotherapy. The median total dose was 60 Gy (2 Gy/Fraction,30 fractions,completed in 6 weeks).ResultsThere were 52 cycles in all and mean 2 cycles per patient.CR occurred in 7 patients (26.9 ％),PR in 17 patients (65.4 ％) and SD in 2 patients (7.7 ％).The total effective rate was 92.3 ％ (CR+PR).The toxic responses mainly represented as following,myelotoxicity principally showed leucopenia at grade Ⅰ - Ⅱ occurred 46.1％ (12/26) and at grade Ⅲ-Ⅳ 46.1％ (12/26),thrombopenia at grade Ⅰ - Ⅱ occurred 30.8 ％ (8/26) and at grade Ⅲ-Ⅳ 7.7 ％ (2/26),hypohemoglobinemia at grade Ⅰ - Ⅱ occurred 42.3 ％ (11/26) and at grade Ⅲ 15.4 ％ (4/26).Baldness occurred 84.6 ％(22/26). Pain of muscles or arthralgia occurred 69.2 ％(18/26). Responses of gastrointestinal tract at grade Ⅰ - Ⅱ occurred 11.5 ％ (3/26).Radiation induced esophagitis occurred 88.5 ％ (23/26) and tracheitis 19.2 ％ (5/26).ConclusionThe toxic responses of concurrent chemoradiaotherapy with lobaplatin and paclitaxel in advanced esophageal carcinoma are tolerant, and the recent treatment result is good.Further study is needed.

Diabetes mellitus is a chronic disease, it is thus necessary for its patients to participate in its treatment and self-management. The emerging foreign and domestic methods for self-management of diabetes mellitus pa-tients were detected on different Websites and suggestions were proposed for its treatment and self-management in order to improve the quality of life in diabetes mellitus patients.

Objective To analyze the regions of abdominal lymph node metastasis in recurrent thoracic esophageal squamous cell carcinoma ( TE-SCC) after radical surgery, and to guide the design of target volume in postoperative adjuvant radiotherapy. Methods Patients with TE-SCC who were admitted to our hospital from February 2005 to April 2013 were enrolled as subjects. All patients were diagnosed with abdominal lymph node metastasis by imaging after R0 radical surgery. The exact regions of abdominal lymph node metastasis were classified according to the 7th edition of American Joint Committee on Cancer ( AJCC) TNM staging system for gastric cancer, and then retrospectively analyzed. The difference of two group was analyzed by χ2 test. Results Among the 1593 eligible patients, 148( 9. 3%) were diagnosed with abdominal lymph node metastasis after surgery. In the 148 patients, the abdominal lymph node metastasis rates in the upper, middle, and lower thoracic esophagus were 2. 3%, 7. 8%, and 26. 6%, respectively ( P=0. 000);the incidence rates of pathological stages T1/2 and T3/4 were 8. 7% and 9. 5%, respectively ( P=0. 601);the incidence rates of 0-2 and ≥3 metastatic lymph nodes in postoperative pathological examination were 4. 8%and 20. 1%, respectively (P=0. 000). The abdominal lymph node metastasis rate was the highest in the para-aortic lymph node ( 16a2) , followed by para-aortic lymph node ( 16a1) and the lymph nodes around the celiac trunk, posterior area of the pancreatic head, and common hepatic artery ( 64. 9%, 41. 2%, 37. 8%, 32. 4%, and 20. 9%) , yielding an overall metastasis rate of 91. 9%. Conclusions The major regions of abdominal lymph node metastasis in esophageal carcinoma after radical surgery include para-aortic lymph nodes ( 16a2 and 16a1) and the lymph nodes around the celiac trunk, posterior area of the pancreatic head, and common hepatic artery. These regions are the abdominal target volumes of postoperative adjuvant radiotherapy.

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.
