Data acquisition is one of the key links that influencing the quality of clinical research.Electronic data capture system (EDC) embodies the advantages of saving time,manpower and material resources and improving efficiency and reliability by data acquisition.CDISC has established worldwide industry standards to support the electronic acquisition,exchange,submission and archiving of clinical research data.The application of CDISC standards to EDC system is favorable in ensuring the validity and standardization of clinical data.This paper takes the Oracle's OC/ RDC (Oracle Clinical / Oracle Remote Data Capture) system as an example to discuss the application of CDISC standard to EDC system from the two aspects:direct application and indirect application.We suggest that data collection should be taken into account during the design phase of a clinical trial,and the CDISC standard be applied at the CRF design stage.A design for eCRF takes time and effort by the combination of EDC system and CDISC standard,while thoughtless design may collect the wrong data.Therefore,it is suggested that a specialized personnel should be put in charge of eCRF design and maintenance during the operation of EDC system,and a set of standardized eCRFs based on CDISC standard and standard operating procedures should be built in one organization.

Background:Medical treatment and surgery are the two main therapeutic approaches for esophageal variceal bleeding ( EVB),but studies showed that the efficacy of medical treatment was poor,and surgery was invasive and could lead to serious complications. Aims:To investigate the efficacy and safety of endoscopic variceal ligation combined with sclerotherapy for treatment of EVB. Methods:A total of 150 cirrhotic patients with EVB admitted from May 2011 to May 2012 at Wenling Oriental Hospital were enrolled and assigned into observation group and control group by random digital table. Patients in observation group were treated with endoscopic variceal ligation combined with sclerotherapy,and patients in control group were treated with somatostatin and pantoprazole. Overall clinical efficacy,recurrence and adverse effect were compared between the two groups. Results:In observation group,the overall clinical efficacy was 94. 7%(72/76), the recurrence rate was 3. 9%(3/76),and the adverse effect rate was 13. 2%(10/76);in control group,the overall clinical efficacy was 79. 7%(59/74),the recurrence rate was 14. 9%(11/74),and the adverse effect rate was 28. 4%(21/74). Overall clinical efficacy in observation group was significantly higher than that in control group(P<0. 05), while recurrence rate and adverse effect rate were significantly lower than those in control group( P all < 0. 05 ). Conclusions:Compared with medical treatment,endoscopic variceal ligation combined with sclerotherapy is effective in improving the clinical efficacy and reducing the recurrence and adverse effect for treatment of EVB. It is worthy of being used in clinical practice.

OBJECTIVE:
To explore the prophylactic effect of Budesonide on the expression of IL-4,IL-5 in nasal mucosa in model of minimal persistent inflammation of allergic rhinitis in rats.
METHOD:
Eighty SD rats were randomly divided into allergic rhinitis group (A group), experimental (B group), control group (C group) and negative control group (D group). A group was made for model of allergic rhinitis. B and C group were made for model of the lightest persistent inflammatory response. After the models were established, half of rats in the A group, B group, C group and D group were executed, and EOS infiltration and the expression of IL-4, IL-5, ICAM-1 were observed in nasal mucosa. The remaining rats of B group were given budesonide (64 microg/side/time, twice/day) treatment for 2 weeks. A, C, D group were given nasal spray with normal saline for 2 weeks. After that A, B, and C groups were stimulated with 1% OVA daily for one week, D group were given nasal spray with normal saline. All rats were executed after excitation, EOS infiltration and IL-4, IL-5 expression were observed.
RESULT:
After the drug treatment, B group only had a small amount of mucous EOS infiltration and had no significant difference with D group, but in A and C group EOS had heavy infiltration. Gray value of the IL-4 positive areas in B group were significantly different compared with A and C group (P < 0.05), A group and C group had no significant difference (P > 0.05). Distribution of IL-5 positive signals was similar with that of IL-4.
CONCLUSION
Budesonide MPI application could significantly inhibit the allergic.

BACKGROUND: It is demonstrated in modern pharmacologic study that total paeony glycoside (TPG) provides extensive pharmacologic activities,such as inhibiting aggregation of platelets and erythrocytes, anticoagulation,antithrombsis, anti-arterial sclerosis, protecting heart and liver, anti-tumor,etc.OBJECTIVE: Neonatal rat cardiomyocytes were cultured in vitro and by the changes of superoxide dismutase (SOD) activity, malondialdehyde (MDA) and nitric oxide (NO) contents in cell culture solution, the protection of TPG on injured cardiomyocytes was analyzed.DESIGN: Controlled observation was designed.SETTING: Bioengineering Department in School of Life Science and Technology of Xi 'an Jiaotong University and Institute of Bone Diseases in Medical School of Xi'an Jiaotong University.MATERIALS: The experiment was performed in Bioengineering Department in School of Life Science and Technology of Xi 'an Jiaotong University from February to June in 2003, in which, 44 SD neonatal rats aged 1-3 days were employed. The 48-hour-cultured cardioryocytes were prepared in 42 bottles and randomized into 6 groups, named normal control (normal group), medicated-injury group (injury group), TPG 0.625 mg/L group,TPG 3.125 mg/L group, TPG 15.625 mg/L group and positive control, 7 bottles in each group.METHODS: Cardiomyocytic primary culture was performed under aseptic condition. No any drug was used in normal group, isoprenaline was added in injury group to terminate the concentration at 100 mg/L, in TPG 0.625, 3.125 and 15.625 mg/L groups, 30 minutes after isoprenaline added, RGP at dosages of 0.625, 3.125 and 15.625 mg/L were added respectively; in positive control, 30 minutes after isoprenaline added, coenzyme Q10 was used to terminate the concentration as 100 mg/L.Afterwards, the assay of every index was performed. Xanthine oxidase (XOD) method was used to assay SOD activity, thiobarbituric acid (TBA)method was to assay MDA content and nitrate reductase (NR) method was to assay NO content.cell culture solution in each group.Compared with normal group, the levels of total SOD, CuZn-SOD and MnSOD were reduced remarkably in injury group (P < 0.05 or P < 0.01).The above-indexes in every TPG group and positive control were improved to different extents (P < 0.05 or < 0.01), in which, the protection of TPG 15.625 mg/L group was near to or superior to positive control [(79.50±10.67), (80.30±13.50); (48.24±13.26), (49.73±10.23); (31.26±10.22),in cell culture solution in each group: Those in injury group were higher remarkably than normal group (P < 0.01). MDA and NO contents were all reduced in every TPG group and positive control and dose dependence presented in TPG protection, the higher the dose was, the stronger the action of TPG on protection was, in which, in high-dose group, MDA content was near to normal group [(5.41±1.81), (4.48±0.94) μmol/L, P > 0.05] and NO content was similar to positive control [(81.83± 9.08), (82.41±12.37) mol/L,P > 0.05].CONCLUSION: TPG protects myocardial injury induced by isoprenaline,indicating dose-dependence relationship, which is probably associated with enhanced anti-oxidation of cell, reduced injury of cellular membrane induced by free radical and lipid oxidant.
