AIM To study the effects of cyclophosphamide (CTX) on the pharmacokinetics of buthionine sulfoximine (BSO)in Walker 256 tumor bearing rats. METHODS Walker 256 tumor bearing rats were treated ip for 4 days with saline or CTX in saline (20 mg?kg -1 ), then received iv BSO 200 mg?kg -1 . BSO concentration in rat plasma was determined by a reverse phase HPLC with fluorescence detection after precolumn derivatization with o phthaldialdehyde. Compartment model and pharmacokinetic parameters were determined by 3P87 software processed on a computer. RESULTS A single intravenous dose of BSO 200 mg?kg -1 was eliminated from plasma in a two compartment manner in tumor bearing rats. The pharmacokinetic parameters of BSO were as follows: In tumor bearing control rats, T 1/2? =(11 1?2 4) min, T 1/2? =(65?14) min, CLs=(12 8?1 3) ml?min -1 ?kg -1 , AUC=(262?26) mg?L -1 ?h; in tumor bearing CTX treated rats, T 1/2? =(8 2?1 8) min, T 1/2? =(42?3) min, CLs=(13 4?1 9) ml?min -1 ?kg -1 ,AUC=(252?35) mg ?L -1 ?h. CONCLUSION There is no significant difference between the parameters of tumor bearing control and CTX treated rats except T 1/2? .

Objective To assess the effect of resident training in clinical skills on SARS prevention and treatment. Methods A survey was conducted by means of questionnaires on 101 residents of the authors' hospital who were at the forefront of the fight against SARS. Results Training in clinical skills assisted the residents to various degrees in SARS prevention and treatment. 100% of the residents surveyed held that the training was helpful, beneficial and assisted them in solving problems. Conclusion Training in clinical skills, which rendered the residents proficient in basic skills and more capable of clinical application of the skills, also enhanced their ability to handle emergent events in SARS prevention and treatment.

OBJECTIVE:To establish an HPLC method for the determination of gastrodin in Choudongning capsule. METHODS:The sample was determined on Elite C18 column(250 mm?4.6 mm,5 ?m);the mobile phase consisted of methanol -water(3∶97) at a flow rate of 1.0 mL?min-1;the detection wavelength was set at 221 nm. RESULTS:The linear range of gastrodin was from 0.051 ?g to 0.357 ?g(r=0.999 9) and its average recovery was 98.99%(RSD=1.91%,n=6).CONCL-USION:The method is convenient,accurate and reproducible,and it is applicable for the quality control of Choudongning capsule.

OBJECTIVE:To improve the quality of drug consultation.METHODS:The drug consultation records of a total of 1 663 cases in our hospital from July 2004 to July 2007 were analyzed statistically by a retrospective method.RESULTS:Of the drug consultation records of a total of 1 663 cases,the chief questions consulted were adverse drug reactions and long-term medication safety(25.2%),dosage and administration(21.1%),medication for special populations(9.7%),drug interactions(8.1%),pharmacological action and indications(7.1%),and generic name and composition of drugs(5.2%).CONCLUSION:The drug consultation service in our hospital achieved a remarkable efficacy in guiding physicians and pharmacists on rational drug use;however,it has its problems and remains to be improved further.

OBJECTIVE:To establish an HPLC method for the determination of the contents of cinobufagin and resibufogenin in Yigankang capsule.METHODS:The samples were separated on Spherigel ODS C18(150 mm?4.6 mm,5 ?m)chromatographic column with 0.5% KH2PO4-acetonitrile(50∶50,pH was adjusted to 3.2 by phosphoric acid)used as a mobile phase at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 296 nm and the column temperature was kept at 40 ℃.RESULTS:The linear ranges of cinobufagin and resibufogenin were 0.22～1.09 ?g(r=0.999 8)and 0.26～1.30 ?g(r=0.999 9),respectively,and the average recoveries of cinobufagin and resibufogenin were 99.4%(RSD=1.9%,n=9)and 98.7%(RSD=1.4%,n=9),respectively.CONCLUSION:This method is proved to be sensitive,simple,accurate and specific,and it is applicable for the quality control of Yigankang capsule.

OBJECTIVE: To evaluate the efficacy and safety of diammonium glycyrrhizinate in the treatment of drug-induced liver injury according to present clinical studies. METHODS: Retrieved from CBM and the CNKI from 1994 to 2009, literatures about the randomized controlled trials that the effective rate of diammonium glycyrrhizinate was compared with that of other hepatoprotective with drug-induced liver injury and drug-induced liver disease as study subjects. RESULTS: 18 RCTs including 1,644 patients with drug-induced liver injury were enrolled. The effective rate of diammonium glycyrrhizinate group was higher than that of control group, statistical significance was noted in two groups (P

Objective To explore the main affecting factors on sanitary quality of public places and to assess the sanitary quality scientifically. Methods The sanitary qualities of 6 kinds of public places of entertainment in Taiyuan during 1998～2000 were assessed using the method of compreheusive fuzzy assessmeat. Results All of 6 kinds of public places revealed similar sanitary qualities. All of the sanitary indexes accorded with the related National Sanitary Standards. The sanitary qualities were better for ballrooms, theaters, bar and billiard rooms in hotels with Grade Ⅰ quality, and were worse for tennis and bowling halls with Grade Ⅱ quality. The assessments on single index showed that the affecting factors of sanitary quality of public places of entertainment were the levels of CO2, noise and CO. Conclusion The sanitary quality of entertainment public places was better during 1998～2000.

Objective:To investigate the culture technique and secretory function of parathyroid cells in rats in order to establish experimental basis of parathyroid cell transplantation.Methods:After parathyroid glands were digested by collagenase and trypsin,isolated parathyroid cells were cultured.The cells cultured for 5 days were observed by transmission electron microscopy.Parathyroid hormone obtained from the cell culture fluid on day 1,3,5 and 7 was measured respectively.Results:Parathyroid cells cultured for 5 days had abundant rough surfaced endoplasmic reticula、Golgi bodies、stab mitochondria and secretory granules.Cultured parathyroid cells could secrete parathyroid hormone normally,especially on the 5th day.Conclusion:Parathyroid cells cultured for 5 days still possess original morphologic structure and have maximum secreting function,so it is an optimal donor for transplantation.
