| 1 | Valency Study of Vanadium in Stone Coal of Southern China显示文摘Vanadium-bearing stone coal is a new resource of vanadium. V in stone coal mainly exists in three oxidation states: 7.84%V(Ⅲ), 72.08% Ⅴ(Ⅳ) and 20.08% Ⅴ(Ⅴ). The change and distribution of valency of Ⅴ during oxidizing roasting shows that organicmatter in the coal determines valency of Ⅴ at low temperature; at about 450℃, Ⅴ(Ⅲ) is completely oxidized to Ⅴ(Ⅳ); above500℃, temperature is the most important factor for the oxidation of Ⅴ. At 700~1000℃, 92% of Ⅴ in the coal has been oxidizedto Ⅴ(Ⅴ), at still higher temperature no more oxidation of Ⅴ takes place, an equilibrium being established. The roles of NaCl in therecovery of V2O5 from the coal were discussed. The best conditions for roasting are: the oxidation-chlorination atmosphere,temperature 800℃ for 30 minutes, ore: NaCl=100:10,ηroast reaching 90%. | Xu, Guozhen Ge, Nai'e Chen, Jianping Shen, Shaobo | 1990 | Rare Metals1990，10，2： | 3 |

| 3 | Efficacy of Moxifloxacin against Mycobacterium abscessus in Zebrafish Model in vivo显示文摘Objective Moxifloxacin(MFX)shows good in vitro activity against Mycobacterium abscessus and can be a possible antibiotic therapy to treat M.abscessus infection;however,other studies have shown a lower or no activity.We aimed to evaluate MFX activity against M.abscessus using zebrafish(ZF)model in vivo.Methods A formulation of M.abscessus labeled with CM-Dil was micro-injected into ZF.Survival curves were determined by recording dead ZF every day.ZF were lysed,and colony-forming units(CFUs)were enumerated.Bacteria dissemination and fluorescence intensity in ZF were analyzed.Inhibition rates of MFX and azithromycin(AZM,positive control)were determined and compared.Results Significantly increased survival rate was observed with different AZM concentrations.However,increasing MFX concentration did not result in a significant decrease in ZF survival curve.No significant differences in bacterial burdens by CFU loads were observed between AZM and MFX groups at various concentrations.Bacterial fluorescence intensity in ZF was significantly correlated with AZM concentration.However,with increasing MFX concentration,fluorescence intensity decreased slightly when observed under fluorescence microscope.Transferring rates at various concentrations were comparable between the MFX and AZM groups,with no significant difference.Conclusion MFX showed limited efficacy against M.abscessus in vivo using ZF model.Its activity in vivo needs to be confirmed. | NIE Wen Juan XIE Zhong Yao GAO Shan TENG Tian Lu ZHOU Wen Qiang SHANG Yuan Yuan JING Wei SHI Wen Hui WANG Qing Feng HUANG Xue Rui CAI Bao Yun WANG Jun WANG Jing GUO Ru GE Qi Ping NIE Li Hui HAN Xi Qin DU Ya Dong CHU Nai Hui | 2020 | Biomedical and Environmental Sciences2020，33，5： | 1 |
