Objective To investigate the effect of DMARDs on the prevention of early-onset atherosclerosis in rheumatoid arthritis ( RA) patients for exploring an appropriate schedule to reduce cardiovascular events. Methods Seventy-two patients with early RA were included in this study. Erythrocyte sedimentation rate ( ESR) and high sensitivity C reactive protein ( hs-CRP) were detected before and after treatment to evaluate inflammation. Carotid intima-media thickness ( cIMT) and endothelium-dependent flow-mediated vasodilatation (ED-FMD) were monitored. Disease Activity Score in 28 Joints (DAS28) and health assessment questionnaire-disability index ( HAQ-DI) was used to assess severity degree of RA and life quality of the patients, respectively. The patients were treated with methotrexate (MTX), hydroxychloroquine (HCQ) and sulfasalazine (SSZ) alone or combined based on severity of RA. Results After 1 year of treatment, ESR, hs-CRP, DAS28 and HAQ-DI were significantly improved (all P<0. 01). At the same time, the serum lipid levels also had obvious changes. However, there was no obvious difference in body mass index ( BMI) after 1 year. The cIMT ratio value was significantly decreased compared to baseline (0. 43±0. 08 mm vs. 0. 50±0. 16 mm, P=0. 002), and FMD% also significantly improved from basic value of 5. 26 to 7. 57 after treatment (P=0. 041). Conclusion Early intervention of RA by using DMARDs can effectively control the disease and slow the progression of atherosclerosis, but also reduce cardiovascular mortality.

Objective To abserve the acute toxicity in mice administered with Wuweizi Ningshen oral liquid.Methods The maximum administration dosage(MAD)of Wuweizi Ningshen oral liquid were determined by administration intragastricly in mice.Wuweizi Ningshen oral liquid was administered for 2 weeks,and the growth condition,body weight growth and index of main viscera were measured.Results The index of growth condition,body weight growth and index of main viscera were in normal ranges.Conclusion It could be concluded that Wuweizi Ningshen oral liquid is safe to be administered in the dose prescribed.

OBJECTIVETo find out the situation of the implementation on "rules on stop smoking in the public places in Beijing", a study was carried out to compare the results from 1997 and 2001.

METHODSThousands of residents aged above 15 in a family were sampled by stratified sampling, and 4 districts were selected as study locales.

RESULTS(1) About 40% of the department or school leaders considered much about the work on banning of smoking with 70 % of the departments or schools having posters of signs on 'ban on smoking' in the meeting rooms. (2) Some of the departments or schools had inspectors looking after the issue. (3) 60% of the people had never or 10% had seen that the inspectors ever criticizing or punishing the smokers who violating the rules. (4) People still often saw some one would smoke in public (the rates were 19.53% , 37.89% , 6.35% respectively in 1997,2001,2004 ). (5) People received the information of these rules through TV news or newspaper.

CONCLUSIONAlthough success had been achieved since the implementation of the Rules, it did not seem to have had substantial progress.

Objective To establish the pyrogen removing effect of activated carbon in the technics of traditional Chinese medicine (TCM) injections. Methods The content of bacterial endotoxin concentration was detected by kinetic turdimetric assay to evaluate the effect of removing pyrogen before and after using activated carbon in concentrated solution of TCM injection. Results The activated carbon adsorption rate of Shuanghuanglian concentrated solution≥70%and the activated carbon adsorption rate of Danshen concentrated solution>95%. Conclusion Pyrogen manufacturing process is scientific and rational by adding activated carbon adsorption in powder injection of TCM. The bacterial endotoxin of large doses can't be removed fully by activated carbon adsorption.

Objective To explore a technical modification by transperineal Da- W anorectoplasty (Da WARP) on treating low, intermediate anorectal anomalies(AA) and to evaluate the results of long - term follow up. Methods Forty six cases of AA underwent a Da-W ARP,which involved preservation of the rectal end of the fistula and invagination of the perineal skin flap through the neoanus.The clinical records were reviewed and analyzed retrospectively. Results The median follow - up period was 7 years and 2 months. All of them achieved a good fecal continence exception of 1 patient with intermediate AA and associated anomaly,had fair result. Conclusions The Da - WARP is relatively simple and practical methods for surgical treatment of low, intermediate AA, with good long - term results.

Results:The MMP3 biosensor vector was successfully constructed.The length of MMP3-YPet identified by double enzyme digestion and PCR was about 780 bp.The transfection efficiency of MMP3 biosensor was about 40%,and which was evenly presented in cytoplasm of 293T cells.And the FRET ratio of MMP3 biosensor was decreased after stimulation with uPA on the 293T cells. The FRET ratio reached its minimum about 30 min later. Conclusion:The MMP3 biosensor can sensitively and reliably monitor the MMP3 activation in living cells.

Objective To construct the eukaryotic expression vector urokinase-type plasminogen activator (uPA) biosensor which was the composition of the fusion protein enhanced cyan fluorescent protein-uPA (substrate)-yellow fluorescent protein variant (ECFP-uPA substrate-linker-YPet).Methods By the template Src-biosensor, the YPet primers were designed by Primer Premier 5.0 software,and the restriction enzyme sites,uPA substrate gene sequence and linker were added in its 5′ end. With the intermediate vector pDMTM-18T, an eukaryotic expression vector which contained a fusion protein of ECFP-uPA substrate-linker-YPet was constructed by genetic engineering.Then the uPA biosensor was transfected into 293T cells.The transfection efficiency and expression of fusion proteins were observed after 24 h.Fluorescence resonance energy transfer (FRET)was observed by the inversion fluorescence microscope and measured by the MetaFlour FRET 4.6 software. Results The uPA biosensor vector was confirmed by the fragment of PCR and double restriction enzyme digestion.The transfection efficiency was nearly 40%.The immunofluorescence detection results displayed that uPA biosensor fusion protein expressed in the 293T cells membrane and the FRET of uPA biosensor in the living 293T cells was observed after incubation with the recombinant human uPA (rhuPA).Conclusion uPA biosensor is successfully constructed and it could be used as a molecular probe to study the temporal and spatial variation of uPA in living cells.
