Although Dr. Burstein agrees that metronomic chemotherapy alone "did not do all that much," he told Medscape that the combination with bevacizumab is encouraging and that a pilot study is being designed to look at the feasibility of combining bevacizumab with metronomic chemotherapy. The study will compare the combination treatment with bevacizumab alone, but it will not look at metronomic chemotherapy alone.28th Annual SABCS: Abstract 4. Presented Dec.
虽然Burstein医师同意仅接受节律性化学疗法几乎是没有帮助,但他向Medscape表示,结合bevacizumab的合并疗法是有潜力的,而且已经有初期试验检验结合bevacizumab与节律性化学疗法的可行性;这项试验将会比较合并试验与仅接受bevacizumab治疗的反应,但并不会检验仅接受节律性化学疗法的效果。

In the thesis, a series of novel single and multi-armed oxadiazole bridging ligands and pyridyl-4, 5-imidazole dicarboxylic acid ligands have been synthesized. The coordination chemistry of these novel ligands with transition metal ions was investigated. In addition, two 1, 3, 4-oxadiazole bridging ligands end-capped by chelating Schiff-base coordination sites have been designed and synthesized. The coordination chemistry based on one of the two ligands with metal ions was primarily investigated.

The contents of mineral elements, like Fe, in LMTCMs were higher than that of nor-LMTCM. The result of analysis of mineral element of 14 LMTCMs by ICP-MS method also showed the content of Fe have something to do with lung meridian tropism effects. The result of the study of platycodon radix approved the laws too. These laws were used to predict if the marine medicines have the lung meridian tropism effects.2. The Compatibility laws of Medicines and their chemical composition in LSP were studied by mining the data of the constituent herbs and their chemical composition. The results showed that the most constituent medicines of lung system prescriptions have lung meridian tropism. Radix glycyrrhizae, herba ephedrae, semen armeniacae amarum, fructus schisandrae Chinese and their compatibility are common in lung system prescriptions. Terpene, alkaloid, steroid, and flavanoid compounds and their compatibility are common in lung system prescriptions.3. The marine phycophyta medicines of LSP were studied by the same method.

Additionally, 75 volatile chemical constituents have been identified from the petroleum ether extracted part by capillary GC-MS, and the relative percentages of them are determined by GC method. The result showed that the volatile constituents of Musella lasiocarpa mainly includes advanced alkane, aliphatic acid and ester, aldehyde, ketone, aromatic and its heterocyclic compounds. With the compounds that have been isolated and identified from Musella lasiocarpa, the biogenensis pathway of new compound MT-3 is approached. Furthermore, the bacteriostasis of the 6 compounds to Escherichia coil, Pseudomonas aerusinosa, Bacillus megaterium, Sarcina lutea and Bacillus subtilic are determined by flat dilution method.
