Objective To test the pathogeny of Vibrio cholerae strains of the epidemic in Jinzhou of Hubei Province.Methods Traditional methods of biochemistry,immobihzation test,string test and typing of blood serum were used to test the 6 strains isolated.The virulence gene which was cholera enterotoxin (ct) was detected by PCR.The whole genome DNA finger print of confirmed strains was analyzed by pulsed field gel electrophoresis (PFGE) after digestion respectively with two enzymes Not Ⅰ and Sfi Ⅰ.The DNA fingerprints were analyzed for clusters.Results The 6 strains of Vibrio cholerae were all O139 by traditional laboratory tests;virulence gene was detected in all 6 strains.The banding pattern was the same in the two maps of PFGE.The results of cluster analysis showed that the similarity coefficient of the six strains was 100％.Conclusion The epidemic of Vibrio cholerae is caused by the same pathogenic bacterium which is O139.

AIM:To seek a simple and reliable process for extracting effective components in Diedahuoxue film.METHODS: According to uniform design, five factors in extraction were optimized, i.e. ethanol concentration, reflux time, reflux times,ethanol volume and drug particle. The absorption value was taken as evaluating parameter in UV- spectrophotometry. RESULTS: The results showed that the best extracting conditions were 95% ethanol, ten times amount of ethanol, 0.2mm size of particle and reflux time of 1h with 4 repetitions.CONCLUSION:This process is simple and reliable.

OBJECTIVE:To investigate the characteristics of ARDs induced by ciprofloxacin lactate.METHODS:Using philometric method,65 cases developing drug adverse reactions to ciprofloxacin lactate,reported in domestic journals during the past 2 years,were analysed.RESULTS:Of the ARDs in 65 cases,40 were allergic reactions(61.5%),13 reactions of nervous system(12.3%),3 kidney function damage(4.6%),1 liver function damage,1 cardiovascular reaction(1.5%) and 6 reactions of urinary system.CONCLUSION:The ARDs should be under consideration in choice of ciprofloxalin lactate.

Transgenic animals are those in which recombinant DNA technology is used to remove a gene or a specific part of DNA with exogenous DNA, which is hereditable and can be expressed stably. Transgenic rodent technology, first demonstrated by Gordon in 1980,opened the door to the next step in biotechnology and gene regulation, which has been used to reproduce or mimic a part of a human disease in a complex cellular environment by creating in vivo models with germ line transmission of the introduced genetic regulatory elements. Animal models for drug discovery are developing increasingly, which is promoting the research and development new drugs greatly. The use and development of transgenic animals in pharmacological research is reviewed in this article.

OBJECTIVE:To establish UV-spectrophotometry method in the determination of metformin hydrochloride in compound metformin hydrochloride tablets.METHODS:The determination was carried out with water as the solvent under the detection wavelength of233nm.RESULTS:There was a good linear relationship between metformin hydrochloride and its absorbability(r=0.9999)within the concentration range of1～10?g/ml.The average recovery was99.3%with RSD at0.24%(n=9).CONCLUSION:The method is accurate,fast,convenient,and which can be used to determine the contents of metformin hydrochloride in compound metformin hydrochloride tablets directly without isolation.

Objective To investigate the effectiveness and feasibility of cardiovascular computed tomography angiography(CTA) in 128-slice DSCT with low tube voltage and low dosage contrast media in children with tetralogy of Fallot (TOF). Methods Forty patients with TOF were randomly divided into group A and group B by random number table method, patients in group A received a conventional scan with 80 kVp and contrast media of 1.2 ml/kg, patients in group B, 70 kVp and contrast media of 1.0 ml/kg were used. The injection time of the two groups were both fixed for 12 s. CT attenuation, image noise and signal-to-noise ratio (SNR) of ascending aorta, the main pulmonary artery, left ventricle and right ventricle were quantified. Radiation dose and volume of the contrast medium were recorded. Subjective image quality was assessed by two radiologists in consensus. The Student's t test was performed to analyse the differences between the two groups regarding CT attenuation, image noise, SNR, radiation dose and volume of the contrast medium. The image quality scores between the two groups were compared by using the Mann-Whitney U test. Results No significant difference was found in the attenuation, noise, SNR between the two groups in the same evaluated anatomic regions and no significant difference was found in the image quality. Effective dose (ED) was(0.17±0.05),(0.13±0.04)mSv respectively, there was significant reduction in group B than that in group A (t=2.48, P=0.019). The consumed iodine amount was(10.00±1.84),(8.29± 1.45) ml respectively, there was significant reduction between the two groups (t=2.89, P=0.007). Conclusions In children with TOF, the cardiovascular CTA with diagnostic quality can be adequately acquired with low tube voltage (70 kVp) and low concentration contrast media (1.0 ml/kg), there is significant reduction in radiation dose and contrast medium amount.
