OBJECTIVE:To establish a HPLC method for the determination of gentamycin sulfate C component in medicinal albumin gel. METHODS: Samples was separated on Agilent ZORBAX Eclipse XDB-C8 at a column temperature of 26℃. The mobile phase was methanol-acetic acid-water (70∶5∶25, added with 0.02mol?L-1 sodium heptanesulfonate solution) for gradient elution at a flow rate of 1.0mL?min-1. The detection wavelength was set at 330nm. RESULTS: Baseline separation of gentamycin sulfate C component in medicinal albumin gel was achieved. The linear range of gentamycin sulfate C component was 0.26?g～6.50?g and its average recovery rate was 90.0%, RSD=0.43%, the lowest limit of detection was 0.368ng. CONCLUSION: The method was proved to be simple, accurate and reliable, and suitable for the content determination of gentamycin sulfate C component in related preparations.

Objective To manifest the angiogenic effect and heart function improvement of transplantation therapy through the experiments of porcines. Methods The coronary arteries of porcines were ligated to create myocardial infarction and then the bone marrow mononuclear cells were injected into the coronary artery. Three weeks after transplantation the heart function was measured by echocardiography and left ventricular angiography. The myocardial blood perfusion was measured by single photon emission computerized tomography. The number of microvessels was also counted. Results After the injection of bone marrow mononuclear cells, left ventricular angiography showed the increasing of dP/dt. The myocardial blood perfusion measured by single photon emission computerized tomography increased. Collateral vessels occurred, and the number of vessels was higher than that of the control (56.6?11.7/mm2 vs. 37.2?8.4/mm2,P

Objective:To explore the effect of bilingual teaching applied to the classes of histology and embryology.Methods The bilingual teaching was tentatively preformed in a part of the undergraduates in our school during their classes of histology and embryology.Results The effect of bilingual teaching was obviously superior to the traditional one.The theory examination scores and the ability of reading and using professional English were higher in the class which employed the bilingual teaching than in the control ones.Some students thought that the bilingual teaching could mobilize their activities.Conclusion The application of bilingual teaching in Histology and Embryology has a positive significance to improve the quality of teaching.

Objective To know the blood level and the influencing factors for the children living in the area near highway in the mountain region. Methods From December,2006 to April,2007,one hundred and eighteen children aged 8-12 years (exposed group) living in the area near highway in the mountain region and fifty-one children aged 8-12 years (control group) living in the area far away from the highway were selected by random cluster sampling. Lead level of the soil and crops on the highway-sides (pollution area)and the area far away from the highway (control area) was determined. The basic situation was investigated by the questionnaire, the blood lead level was determined by graphite furnace atomic absorption spectrometry. The influence of lead on children's intelligence, physical growth and the influencing factors for blood lead level were analyzed. Results The average lead level of the soil [(96.89?15.05) mg/kg] and crops [(0.86?0.29) mg/kg] in the polluted area was significantly higher compared with the control [soil lead: (29.83?1.41)mg/kg,crops lead:(0.17?0.03) mg/kg], and revealed statistical significance respectively (P

Objective To investigate the body burden of lead and the related health effects in the residents living on the highway-sides of the mountain areas in Fujian province,China.Methods Eighty-nine subjects living nearby the highway-sides(exposed group) and 69 subjects far away from the highway(control group) were recruited by stratified random sampling method.Their basic situation and relevant index were investigated with questionnaire;The lead levels of blood and urine were determined by graphite furnace atomic absorption spectrometric method and compared;The temperature,pulse rate and blood pressure were taken to analyze the related health effects;and the influence factors of blood lead levels were analyzed by single factor analysis method,rank correlation analysis method and multiple regression analysis method.Results The blood and urine lead level of exposure group([94.19 26.51),(15.36?7.67)?g/L ]were significantly higher than that of the control group[(62.83?13.33),(7.24?4.62) ?g/L;t=8.981 0、7.766 2,P

OBJECTIVE:To identify different origin of Scutellaria amoena CH Wright and Scutellaria baicalensis Georgi indexed in China Pharmacopeia by HPLC fingerprints.METHODS:RP-HPLC method was adopted in which the samples were separated on Zorbax SB-C18(250mm?4.6mm,5?m)column at a column temperature of 30℃.The gradient elution was performed on the mobile phase which consisted of acetonitrile(contairing 1.0% methanoic acid)-water(containing 1.0% methanoic acid)at a flow rate of 1.0mL?min-1.The detection wavelength was set at 274nm.RESULTS:The fingerprints of Scutellaria amoena CH Wright that from different places were of great resemblance,so were the fingerprints between Scutellaria baicalensis Georgi that from different places,but the fingerprints between Scutellaria amoena CH Wright and Scutellaria baicalensis Georgi were of significant difference,with resemblance of only 0.859.CONCLUSION:The RP-HPLC fingerprint serves as basis for the further study of the quality criteria of Scutellaria amoena CH Wright and Scutellaria baicalensis Georgi.

OBJECTIVE: To faciliate the implementation of the new Prescription Administrative Policy in ward area pharmacy. METHODS: Based on our practical working experience, the Prescription Administrative Policy was studied from perspective of quality of personnel, sense of responsibility and drug standards etc. And the difficulty encountered in the implementation of the prescription administrative policy was explained. RESULTS & CONCLUSIONS: Solving such problems as including medical orders in prescription management, clarifying the responsibility of irrational medication without sticking to instrcutions of drug package inserts, the demanding requirements on pharmacists’s quality and the enforcement of precription evaluation contributes to the implementation of the new Prescription Administrative Policy in ward area pharmacy.

Objective To evaluate the efficacy of the end point of catheter ablation of pulmonary vein (PV) foci initiating atrial fibrillation (AF) to guide the catheter ablation of PAF Methods Thirty two drug resistant PAF patients withdrew all antiarrhythmias drugs for one week and received Holter monitoring on dyas 7, 5, 3, and 1 before operation, respectively During the operation, focal ablation was performed in the patients whose target PV could be documented, and all pulmonary veins os and isthmus of right atrium were ablated in the other patients All patients received Holter monitor on days 1,3,5, and 7 postablation, respectively If PAF relapsed after the first operation, the patient would undergo operation again until no AF was documented The patients were followed up for 3 to 20 months Results Total 82 PV in 32 patients were success isolated In foci ablation patients, 9(60 0%) patients successed by one operation, and 6(40 0%) patients successed after the second operation In all PVs isolation patients, 9(47 0%) patients successed by one operation, and 10 (58 8%) patients successed after the second operation, and the success rate was 11 (64 7%) after the third operation The overall success rate was 81 3% Conclusion The endpoint of PAF ablation should be no AF recurrence when no antiarrhythmias drugs were administrated The success rate was higher in the patients who had clear target PV and the overall success rate could be improved by the ablation once again
