Objective To observe the changes in endothelin(ET), nitric oxide(NO) and C-reactive protein(CRP) before and after the rosiglitazone therapy in patients with impaired glucose tolerance(IGT). Methods 72 IGT patients were divided randomly into 2 groups: rosiglitazone group(n=45) and placebo group(n=27). 15 weeks later, the efficacy of rosiglitazone was compared. Results The levels of ET, CRP were decreased and NO increased significantly in rosiglitazone group compared with those before treatment (ET 54.8±10.0 pg/ml vs 72.8±24.3 pg/ml, P<0.01;CRP 4.58±0.38 mg/L vs 5.99± 0.85mg/L, P<0.01 ; NO 41.0±10.0 μmol/L. vs 31.3±9.0 μmol/L, P<0. 01)). However, the levels of ET,CRP and NO in placebo group did not change singnificantly (P>0. 05). Conclusions Rosiglitazone can singnificantly improve ET, NO, CRP level in IGT patients, which means an additional effect of rosiglitazone on the correlation of inflammation and endothelial disturbance.

Hypoxanthine,the pre_substance of uric acid,was used to create mouse model with hyperuricemia.The dose_effect relationship and time_effect relationship of hypoxanthine during the model establishment were observed.The effect of sex and xanthine oxidase inhibitor on the establishment of mouse model was studied.The results showed this method is effective for the establishment of a stable mouse model with hyperuricemia.

Objective To understand the mastery situation of the knowledge about common infectious diseases among the prima-ry and middle school students,in order to provide the evidence for the prevention and treatment of infectious diseases.Methods The stratified random cluster sampling method was adopted.The survey was performed by the questionnaire form.The data were analyzed by the Chi square test,logistic regression model in the SPSS17.00 statistical software.Results Among the primary and middle school students in Chongqing,the students mastering 75% of the basic knowledge about infectious diseases accounted for 24.6% of the total respondents (P<0.01).From the view of the distribution of disease entities,the top six diseases with the awareness rate of less than 60% were hepatitis B,bacterial dysentery,cholera,measles,pinworm and rabies respectively(P<0.01), whose awareness rates are under 60%(P<0.01).As for the level of mastery among different grades,the senior middle school students had a better knowledge of tuberculosis,flu,SARS,AIDS,hepatitis B,poliomyelitis,etc(P<0.01).Comparatively,the pri-mary school students grasped the knowledge of hand-foot-and-mouth disease and pinworm better(P<0.01).Conclusion The pri-mary and middle school students have a low awareness rate of infectious diseases.Pertinently strengthening the popularization of the knowledge about infectious diseases is the powerful measure for reducing the occurrence of infectious diseases and promote the healthy development of students.

Objective To explore the sub-health and TCM physical constitution of stroke patients’families.Method Four hundred and twelve family members of stroke patients hospitalized during September 2001 to May 2013 were involved in the survey by filling out TCM physical constitution scale(TCMPC)and the sub-health self-rating scale(SSS)for the purpose of investigating the sub-health and conditions of TCM physical constitution.Results Of all the patients,189 were in sub-health,accounting for 45.87%. There were 7 main clinical symptoms related to sub-health,including poor sleep,less activeness,proneness to upsets and irritation, memory loss,depression,tension in interpersonal relations and appetite loss,with the incidences ranging from 64.55%to 48.15%. In TCM,51.85%of the family members were balanced in physical constitution,10.58%of them had Yang-deficiency constitution, 14.29%of them had Yin-deficiency,23.28%of them other kind of constitution.Conclusions The family members of stroke patients have a high rate of sub-health.The members in sub-health hold a balanced constitution,Yang-deficiency or Yin deficiency.In order to eliminate their sub-health,improving the quality of care for patients with stroke,we should guide the families of stroke patients to develop good living habits,strengthen the TCM mental nursing,help them to establish a good social support system.

The toxic effects of immunosuppressants are often dangerous factors which influence long-term survival of recipients.Individualized immunosuppressive therapy has been a hotspot and difficulty for comprehensive treatment of liver transplantation.Immunosuppressive therapy has been gradually developed to pursue long-term survival for receipients and graft,minimized side effects of immunosuppressants,optimized quality of life of patients,and reduce the economic burden of patients.Through consideration of patient's pathophysiological state,understanding the characteristics and side effects of various immunosuppressive,appropriate choose of the immune inhibitor,correct evaluation of immune state of recipients and graft,minimization of drug doses,individualized dosing regimen could be successfully carried out.

Objective To screen and identify protein interacted with enterovirus 71 (EV71)3A protein by means of T7-phage display system.Methods The prokaryotic expression vector of 3A protein was constructed for expressing and purifying 3A pro-tein.With 3A protein as the target protein,the T7-phage display system was adopted to screen the human hepatocyte cDNA library. The screened products were performed the DNA sequence analysis and the homologous research.Results 3A protein was expressed and purified,after 4 rounds of biopanning,37 positive clones were selected.The inserted fragments were amplified by PCR using specific T7 primer.The products were sequenced,2 proteins were identified to interact with 3A protein by homologous analysis. Conclusion Trough the T7 phage display system,two proteins interacted with 3A are obtained.The possible function of 3A protein can be speculated by researching the function of these two proteins,which lays the foundation for the further studying the pathogen-ic mechanism of EV71.

Objective To study the clinical features of patients with intracranial ependymal tumour, and explore the prognostic factors which have.a significant association with the outcome. Methods Eighty-three patients with histologically proven ependymal tumour were retrospectively reviewed. The tumour location, the patients' age, the histological features, imaging characteristics, surgical management and adjuvant therapy were studied. Results In 83 cases of intracranial ependymal tumour,41 cases were infratentorial and 42 cases were supratentorial ependymal tumour, 37 patients age ≤15 years, while 46patients age ＞ 15 years. Fifty-eight patients ( 69.9% ) and 25 patients (30.1% ) had low (WHO Ⅰ - Ⅱ ) and high-grade (WHOⅢ) tumors respectively. Sixty-reven (80.7%) patients had gross total resection and 16patients ( 19.3% ) had subtotal resection. The 5-year survival rate was 81.9%( 68/83 ). The factors that were found to have a statistical significance association with the outcome were the extent of the resection and the pathologic characteristics. Conclusions Gross total resection of these tumors results in a good long-term outcome. Reoperation should be considered, if feasible, to remove residual malignant tissue. Anaplastic ependymomas carries a much poorer prognosis. Radiotherapy may play an important role in their treatment.The role of chemotherapy appears limited but can be attempted, especially in the very young, in order to avoid the deleterious effect of radiotherapy.

Objective To observe the results of bone bolt crews in treatment of the haplo-detached distal tibiofibular joint.Methods The haplo-detached distal tibiofibular joint were fixed with bone bolt in 7 patients.Their outcomes were evaevaluated according to Mast and Teipner criteria and X-ray.Results All 7 patients were followed up from 12 to 36 months.All were assessed as good,and no fair or poor cases were found.Conclusion Bone bolt fixation was believed to be a good method to treat the haplo-detached distal tibiofibular joint with simple operation,beared shear force and control of brew tightress and was helpful in weight loading and functional exercises in the earlier period after operation,so bone bolt fixation was good in practical value in clinc.
