Reductive degradation of chloramphenicol in bioelectrochemical system / 生物工程学报

In this study, we investigated reductive degradation of nitroaromatic antibiotic chloramphenicol to non-effective antibacterial amine product in fed-batch biocatalyzed electrolysis systems (BES) (applied voltage was 0.5 V) under low temperature (12 +/- 2 degrees C). The ohm resistance of the whole BES reactor increased when the phosphate buffer solution concentrations decreased. Efficiencies (ErCAP) of chloramphenicol reduction with biocathode (PBS, 25 mmol/L) in presence of glucose was (86.3 +/- 1.69)% within 24 h and sludge fermentation liquor was (74.1 +/-1.44)% within 24 h. While the ErCAP of abiotic cathode under the same condition was only (57.9 +/- 1.94)% within 24 h. It suggested that biocathode could be a promising technology for reductive biodegradation of nitroaromatic antibiotics-containing wastewater in areas with relatively low annual mean temperature.

Effect of Rupiling Granules for Cyclomastopathy:An Observation of 240 Cases / 中药新药与临床药理

Objective To evaluate the clinical safety and therapeutic efficacy of Rupiling Granules in treating cyclomastopathy (classified into deficiency of liver and kidney,disharmony of thoroughfare and Ren channels or complicated with syndrome of qi stagnation,blood stasis,or phlegm blended with blood stasis). Methods A randomized,double-blinded,positive drug controlled parallel polycentric trial was carried out. Results Rupiling Granules showed good therapeutic effect on reducing lump in breast,relieving pain of breast,improving TCM symptoms scoring. Conclusion Rupiling Granules is safe and effective for the treatment of cyclomastopathy (deficiency of liver and kidney ,disharmony of thoroughfare and Ren channels or complicated with syndrome of qi stagnation,blood stasis,or phlegm blended with blood stasis)
