Antibiotics being currently the most extensively used medicine in clinical practice and abuse of them being prevalent, it is thus necessary to monitor in an effective and systematic manner the rational use of them. Based on the existing database and network of hospital information system, a monitoring system for the rational use of antibiotics was successfully developed using the development tool of PowerBuild. This functionally powerful and easy-to-use system, which provides comprehensive and reliable information, improved work efficiency and managerial level by automatically monitoring many chief indicators of antibiotic usage, including dosage, resistance, combination with other drugs, course, pathway, usage during the perioperative period, usage for preventive purposes, therapeutic effect, and the ratio of hospital infection occurrence resulting from the use of antibiotics under different circumstances.

Objective To study the role of transforming growth factor-?1(TGF-?1) and bone morphogenetic protein 2 (BMP2) in the ankylosing spondylitis, and to evaluate whether synovial levels of TGF-?1/ BMP2 mRNA and TGF-?1/BMP2 protein expression correlate with disease activity and macroscopic observation during arthroscopy. Metheds TGF-?1/BMP2 mRNA and protein were detected by in situ hybridization and immunohistochemistry.The vascular morphology of synovial membrane was assessed for vascular morphology, tortuous vessels, straight vessels, vascular density, synovial hypertrophy, by 2 blinded observers and Reece's method using a validated VAS methods. They were significantly higher in AS than that in RA in different synovial regions. Results TGF-?1 mRNA and TGF-?1 expression were significantly higher in early AS than that in early RA in perivascular region and sublining interstitial tissue. BMP2 mRNA and BMP2 expression were significantly higher in AS than that in RA in different synovial regions.No significant relation was found between TGF-?1/BMP2 expression and CRP/ESR/platelet count in early AS. A positive relation was found between the TGF-?1 and synovial hypertrophy in synovium lining layer region, and between TGF-?1 and straight vessels,vascular density in perivascular region, and between BMP2 and synovial hypertrophy in sublining region in early AS. Conclusion Expression of TGF-?1 mRNA and TGF-?1 protein is higher in AS synovial tissue than that in RA. BMP2 mRNA and BMP2 expression are significantly higher in AS than that in RA.

Objective To evaluate the effects of endogenous NO on the chemosensitivity of human breast cancer cell. Methods MCF-7 cells were cultured as monolayer, incubated with cytokine IL-1β. The pro-duction of NO was detected by NO assay. The expression of iNOS protein was measured by Western blotting. Establishing control group and experimental group, the chemosensitivity of MCF-7 cells incubated by L-NMMA and L-Arg to ADM and 5-Fu was studied by MTT assay. Results There was a positive correlation of dose-dependence between NO production and IL-1β concentration. MCF-7 cells expressed plenty of iNOS by induetion of IL-1β. There was no significant difference on iNOS whether L-NMMA and L-Arg existed or not. Incubating MCF-7 cells with 0. 5 μmol/L or 1 μmol/L ADM, the survival rate of experiment group was remarkablely decreased(P < 0.05) ; L-NMMA significantly increased survival rate of experiment group(P < O. 05) ; L-Arg decreased survival rate of experiment group(P < 0.05). Conclusion The induction of IL-113 in MCF-7 cells can increase the production of endogenous NO, which increases MCF-7 cells' sensitivity to chemotherapy.

Objective To improve the understanding of severe anaphylactic reactions to infliximab retreatment. Methods Delayed hypersensitivity to infliximab in two patients with ankylosing spondylitis who had previously received infliximab and resumed after discontinuation over 4 years were reported and the related literatures were reviewed. Results Two patients ( 1 male, 1 female ) who were diagnosised with ankylosing spondylitis for more than 10 years, both individuals had received infliximab treatment during a clinical trial approximately 4-5 years prior to further therapy. On day 6 after subsequent infusion, one patient had pruritic skin rash covering her whole body, followed by flustered, dyspnea, hypotension and anaphylactic shock, she was successfully treated with epinephrine and glucocorticoid. Another patient experienced a skin rash and itching 9 days after reinfusion, he was successfully treated with antihistaminics.Conclusion A distant infliximab retreatment is associated with high rates of reinfusion reactions, including fever, urticaria, myalgia, arthralgia,even hypotension, dyspnea, laryngeal edema and anaphylactic shock.We recommend careful monitoring of those patients who receive infliximab retreatment, particularly after a lengthy interval.
