Objective To know the stability of 3 kinds of traditional Chinese drug injection with different solvent under different temperature and different storage time,and then reference to safty of clinical durgs. Methods Use particle analyzer,UV SpectropHotometer,pH Determination of three traditional Chinese medicine injection,at different temperatures and different times,the nuanber of particles,pH value,the value of UV absorbance Observe changes. Results The records of experimental data by repeated measures analysis of statistics: Ciwujia Injection,Aidi injection combined with normal saline solution after the particles of ≥ 10μm excess pharmacopoeia standards; ≥ 2μm number of particles is considerable,in the 32～35℃,Ciwujia at T=O min Aidi at T=I80 min ,the number of particles are smaller and with statistical significance,its pH value of the standard range. Xuesaitong injection with glucose injection ≥ 10μm particulate mixture at a higher temperature in excess of pH annacopoeia standards,number of ≥ 2 μm particles in the 4～8℃ and 20～23℃,T=30 min and 60 min time less with statistical significance,and its range of pH value less than pHarmacopoeia. Three kinds of Chinese medicine in the Department's largest UV absorbance peak value and appearance almost unchanged. Conclusions Different drugs in their relative Suggestions of temperature,time and place under intravenous drug use,or better terminal filter,in order to improve the safety of clinical medication.

A salt-tolerant strain GYW capable of decolorating azo dye was isolated and identified as Halo-monas sp.by 16S rDNA.The result showed that the decolorizing salt-tolerant bacteria could survive above the 10% salt concentration and it could decolorize many dyes.The strain had a high decolorizing rate on acid red GR under the condition of pH 7.5,anaerobic 30?C and 10% NaCl.The ion of Cl- strong inhibited the decolorization of acid red GR,and the ion of SO42- affected little on the decolorization,and the lycine addi-tion with the optimal concentration of 200 mg/L could enhanced the decolorization rate under high NaCl concentration.

Single-port and reduced-port laparoscopic radical gastrectomy as the innovative surgery for gastric cancer are gradually accepted nowadays,and more attentions are also paid to single-port and reduced-port laparoscopic radical gastrectomy due to its better cosmetic effect,less pain,lower incidence rate of surgical site infection and more advantages in enhanced recovery after surgery.However,in the early stage,the development of single-port and reduced-port laparoscopic radical gastrectomy were facing challenges and obstacles on account of limited surgical skills,the lack of special laparoscopic instruments,laparoscope and multi-port Trocar.In recent years,the dilemma and difficult situations were gradually resolved following by surgical techniques innovation,laparoscopic instruments and facilities improvement.It is believed that single-port and reduced-port laparoscopic radical gastrectomy will have a good prospect and breakthrough in the field of gastric cancer treatment in the future.
