Objective To evaluate the effectiveness and safety of recombinant human endostatin combined with concurrent chemoradiotherapy versus concurrent chemoradiotherapy for advanced non small cell lung cancer ( NSCLC) . Methods Electronic databases including the Cochrane library, PubMed, the Chinese biomedical literature database, China national knowledge internet(,EMbase,VIP and Wanfang database system were searched,until August,2013. The inclusion criteria was efficacy and safety studies of randomized controlled clinical studies in which recombinant human endostatin combined with concurrent chemoradiotherapy was compared with concurrent chemoradiotherapy alone for patients with advanced NSCLC. Cochrane handbook 5. 1. 0 was applied in evaluating the quality of included trials and RevMan 5. 1. 0 software was used for data analysis.Results Five studies including 217 cases of advanced NSCLC were included. The results of the meta-analysis exhibited that compared with concurrent chemoradiotherapy alone, recombinant human endostatin combined with concurrent chemoradiotherapy could increase effective rate [OR=2. 62,95%CI(1. 41,4. 86),P=0. 002]. But there were no significant differences in clinical benefit rate [OR=2. 08,95%CI(0. 92,4. 73),P=0. 08],one year survival rate [OR=1. 18,95%CI(0. 53,2. 66),P=0. 68], improvement in quality of life [OR=1. 57,95%CI(0. 40,6. 07),P=0. 52],rate of leucopenia [OR=1. 25,95%CI(0. 72,2. 17), P=0.43],radioactive esophagitis [OR=1. 16,95%CI(0. 42,3. 21),P=0. 77] and radiation pneumonitis [OR=2. 47,95%CI (0. 34,17. 68),P=0. 37]. Conclusion Compared with concurrent chemoradiotherapy alone,recombinant human endostatin combined with concurrent chemoradiotherapy may be more effective for advanced NSCLC,whereas improvement of life quality and toxicities are similar. For the quality restriction and possible publication bias of the included studies,more high quality randomized controlled trials are required to further verify this conclusion.

Objective To investigate the hydrophilic chemical constituents from Thesium Chinensis Turcz.Methods The water extract of Thesium Chinensis Turcz.was adsorbed onto AB-8 resin column and eluted with 50% ethanol to give the hydrophilic portion TT50.TT50 was further separated and purified by repeated column chromatography on silica gel,Sephadex LH-20.The structures of these purified compounds were identified by NMR spectral analysis and comparison with the reported data.Results Six compounds were isolated and identified as kaempferol(1),kaempferol-3-O-glucoside(2),kaepmferol-3,7-di-O-β-D-glucopyranoside(3),kaempferol-3-O-L-rhamnopyranosyl(1 → 2)-β-D-glucopyranoside(4),kaemperol-3-O-α-L-rham-nopyranosyl(1→2)-[6-O-acetyl]-β-D-glucopyranoside(5),rutinoside(6).Conclusion The main constituents of TT50 were kaempferol glycosides.Compounds 4 and 5 were isolated from this plant for the first time.
