Effect of Tripterygium Glycosides Tablets in treating rheumatoid arthritis:a systematic review and Meta-analysis / 中国中药杂志

To evaluate the effect of Tripterygium Glycosides Tablets extract in the treatment of rheumatoid arthritis( RA). Clinical trials of treating rheumatoid arthritis with Tripterygium Glycosides Tablets published by Meta-analysis were retrieved from EMbase,PubMed,Clinical Trials,Web of Science,Cochrane Library,CNKI,Wanfang,VIP,CBM and Chi CTR,and comprehensively analyzed. A total of 3 studies were enrolled,the modified Sharp score( m TSS),tender join joint erosions( JE) and joint space narrowing( JSN) of Tripterygium Glycosides Tablets group were significant superior to those of control group,including positive drugs methotrexate( MTX) and salazopyridine( SSZ)( P<0. 01). Tripterygium Glycosides Tablets had an effect in treating RA. Due to the small sample size,this study shall be verified with high-quality,large-sample-size double-blinded RCTs.

[An efficient and accurate method for counting target molecules in phage-display peptide library].

The phage titer of samples representing the low, intermediate and high phage number was respectively determined by the double-layer agar plate (DLAP) method and real-time PCR assay. The two methods accurately measured the titer of samples. The plaques from about 1/3 double-agar layer plates could be used to determine the phage titer. The DLAP experiment should repeat 10 times with 10 microl sample each time, while the within-assay coefficient variation (CV) was 4.93%-30.38%. At the same time, the real-time PCR assay only repeated 3 times with 1 microl phage each time, while CV for within-assay ranged from 0.02% to 0.25%. Results indicated that real-time PCR is a simple and quick method for determining bacteriophage titer.

Dynamic concision for three-dimensional reconstruction of human organ built with virtual reality modelling language (VRML).

This research studies the process of 3D reconstruction and dynamic concision based on 2D medical digital images using virtual reality modelling language (VRML) and JavaScript language, with a focus on how to realize the dynamic concision of 3D medical model with script node and sensor node in VRML. The 3D reconstruction and concision of body internal organs can be built with such high quality that they are better than those obtained from the traditional methods. With the function of dynamic concision, the VRML browser can offer better windows for man-computer interaction in real-time environment than ever before. 3D reconstruction and dynamic concision with VRML can be used to meet the requirement for the medical observation of 3D reconstruction and have a promising prospect in the fields of medical imaging.
