Objective:To investigate YKL-40-mediated inflammation in human bronchial epithelial cells and analyzed the soluble factors secreted by bronchial epithelial cells exposed to YKL-40 that were responsible for increasing proliferation and migration of primary normal human bronchial smooth muscle cells (BSMCs).Methods:YKL-40-induced inflammation was assayed in two human bronchial epithelial cells (BEAS-2B cell line and primary human bronchial epithelial cells ,namely HBECs).In addition,we treated BEAS-2B cells and HBECs with YKL-40,and added the conditioned culture media ( YKL-40-BEAS-2B-CM) and ( YKL-40-HBECs-CM) to BSMCs.The proliferation and migration of BSMCs were determined by premixed WST-1 cell proliferation reagent and QCM chemotaxis migration assay ,respectively.Results: Bronchial epithelial cells treated with YKL-40 resulted in a significant increase of IL-8 production,but have no effect about RANTES ,Eotaxin and TNF-α.YKL-40-BEAS-2B-CM and YKL-40-HBECs-CM induced IL-8 was found to further stimulate proliferation and migration of BSMCs ,and the effects were inhibited after neutralizing IL-8.Conclusion:Through investigating the interaction of airway epithelium and smooth muscle ,our findings implicate that YKL-40 may be involved in the inflammation of asthma by induction of IL-8 from epithelium,subsequently contributing to BSMCs proliferation and migration.Moreover, inhibition of IL-8 signaling is a potential therapeutic target for YKL-40-induced inflammation and remodeling of asthma.

OBJECTIVE:To promote hospital rational drug use. METHODS:A total of 1 359 ADR cases submitted to State ADR Center by our hospital from 2005 to 2007 vial network system were analyzed statistically in respect of patients' age and sex,the drugs involved,routes of administration,ADR-involved organs or systems,and turnover etc. RESULTS:Of the total 1 359 cases,25.75% were induced by antimicrobial drugs and 55.33% were induced by intravenous route. The lesions of skin and its accessories were the predominant presentation of ADR,and the majority ADR cases had a good turnover. CONCLUSION:The incidence of ADR can be reduced by strengthening the education on and monitoring of ADR as well as the sense of responsibility of medical staff.

Objective:To show whether the Fas Ligand gene induces mast cells apoptosis.Methods:RT-PCR was used to amplify the gene of rat Fas ligand extracelluar domain and transmembrane domain and cloned it into eukaryotic expression plasmid pcDNA3.1.Transcent transfect RBL-2H3,the expression of Fas ligand RBL-2H3 was detected by RT-PCR、Western blot.The Annexin V FCM was used to detect the RBL-2H3 apoptosis after the transfection of Fas Ligand.Results:It is successful to obtain the gene of rat Fas Ligand extracellular domain and transmembrane segment,cloning it into pcDNA3.1,FasL was expressed on the surface of RBL-2H3 and it's supernatant after the transfection of pcDNA3.1/FasL.The cell start to be apoptosis.Conclusion:Our study reveals that Fas Ligand gene transfection in RBL-2H3 can effectively induced apoptosis.It is a promising strategy for Fas Ligand to be used in the therapy of allergic disease.

Objective To investigate the effect of strengthening intervention management on the compliance, heart func-tion, life quality and prognosis for the patients with chronic heart failure. Methods From September 2013 to September 2014, 100 cases admitted to the Department of Cardiology of General Hospital of Daqing Oil Field in patients with congestive heart failure were selected as the observation objects, they were randomly divided into strengthening the management of intervention group 50 cases and routine management of the intervention group 50 cases, treatment com-pliance and cardiac function index, life quality and prognosis the situation of the patients before and after treatment were compared between the two groups. Results The complete compliance rate of strengthen the management of inter-vention group was 84%, significantly higher than that of the conventional management intervention group (P<0.05). HR, LVEF, CO and E/A of strengthen the management of intervention group significantly improved than the control group, the quality of life scores also improved significantly compared with the conventional management intervention group (P<0.05). And rehospitalization rate of strengthen the management of intervention group was 16.0%, significantly lower than that of the conventional management intervention group, and the mortality rate of strengthen the management of intervention group was 2.0%, was slightly lower than the conventional management intervention group. Conclusion The implementation of strengthening the management of patients with chronic congestive heart failure, can improve the treatment compliance, significantly improve cardiac function and prognosis in patients with heart failure, improve the quality of life of patients with heart failure.

OBJECTIVE: To explore the level and influential factors for out-of-pocket (OOP) expenditure regarding Hunan Provincial Urban Employee Basic Medical Insurance (UEBMI) and to provide evidence for improvement of medical insurance payment system.
 METHODS: Stratified random sampling method was used to obtain 10 527 records of cancer inpatients from January 2011 to December 2014. Social demographic and expenditure information were collected from UEBMI information system. The proportion of OOP expenditure for inpatient and each part of the cost was described. Multiple linear regression was used to analyze main related factors of OOP expenditure.
 RESULTS: The median proportion of OOP for inpatients costs was 20.11%, and remained stable from 2011 to 2014. The main related factors for OOP expenditure were age, civil servant, retirment status, hospital level, cost of hospitalization, hospitalization duration, medicine cost, proportion of general medical service charges, treatment cost, expenses of examination and laboratory test, and cancer type.
 CONCLUSION OOP expenditure among UEBMI cancer inpatients was under control and stable. The level can well reflect the policy preferences. It could be further improved through the control of related factors, particularly the hospital level.
