AIM: To study the linear relationship between pharmacokinetic parameters and doses about potassium clavulanic acid (CAV) and amoxicillin (AMX). METHODS: 15 healthy male volunteers were randomly divided into 5 dose groups. The plasma concentration of CAV and AMX was determined by high performance liquid chromatography (HPLC) method. The pharmacokinetic parameters obtained with 3p97 soft were regressed to corresponding dose. RESULTS: The regression equations of AUC and c max to dose about CAV were Y= 2.0895 X+ 0.4438 (r= 0.9915 ) and Y= 0.9397 X+ 0.1796 (r= 0.9922 ), respectively. The regression equations of AUC and c max to dose about AMX were Y= 4.8795 X+ 2.4794 (r= 0.9988 ) and Y= 1.7276 X+ 1.4832 (r= 0.9935 ), respectively. CONCLUSION: There is good linear relationship between pharmacokinetic parameters and doses about CAV and AMX.

Objective To establish a method of gas chromatography with head-space sampling for determination of five residual solvents ( acetone, ethyl acetate, isopropanol, dichloromethane, acetonitrile ) in raw material drug of cefotiam hexetil hydrochloride. Methods Agilent DB-624 capillary column(30 m×0.53 mm,3.0 μm)was used,with FID served as detector and DMF as the solvent. Results Linear relationships were obtained for the 5 residual solvents in their respective concentration ranges ( r=0.999 6-0.999 9,n=5) ,and the detection range was from 0.071 to 0.847μg. The stabilities measured as relative standard deviations ( RSD) for the 5 residual solvents were from 0.40% to 2.12% ( n=3) . The average recovery rates were 99.03% to 103.33%,and RSD were 0.54% to 3.41% ( n=3) . Conclusion The method is simple,sensitive and accurate for the residual solvent analysis in raw material drug of cefotiam hexetil hydrochloride.

Objective To develop the software of Management Information System of Medical Materials.Methods Based on the platform of NET,three layers of C/S was applied in equipment & apparatus department for good operation platform,frequent data access and rapid response.Besides,the current HIS was utilized to protect the system to be extensible,easily-updated and easily-maintained.Results The application of Management Information System of Medical Materials could meet the requirement in scientific and standard supply,application and management of medical materials.The software was used in scores of hospitals with good effect.Conclusion Being able to organically integrate with other functional module,the software provides a powerful tool for the scientific management of hospital equipment.

AIM: To study the protective effects of HIF-1α gene transfection on hypoxic injury in human HepG2 cells. METHODS: After gene transfection, HepG2 cells were randomly divided into 4 groups: normoxia with Ad-GFP transfected group, normoxia with Ad-HIF-1 transfected group, hypoxia with Ad-GFP transfected group and hypoxia with Ad-HIF-1 transfected group. LDH leaking rate, cell viability, contents of NO and ROS, the iNOS activity were measured. RESULTS: High levels of HIF-1α mRNA and protein were detected in Ad-HIF transfected HepG2 cells. Cell viability was significantly lower in Ad-GFP transfected-hypoxia group than that in Ad-GFP transfected-normoxia group (P<0.05). No marked difference of cell viability was found between Ad-HIF transfected-hypoxia group and Ad-HIF transfected-normoxia group. ROS was significantly higher in Ad-GFP transfected-hypoxia group than that in Ad-GFP transfected-normoxia group (P<0.05), while no marked difference was found either between Ad-HIF transfected-hypoxia group and Ad-HIF transfected-normoxia group or between Ad-HIF transfected-hypoxia group and Ad-GFP transfected-hypoxia group. The content of NO and iNOS activity were significantly higher in Ad-HIF transfected-normoxia group and Ad-GFP transfected-hypoxia group than those in Ad-GFP transfected-normoxia group (P<0.05), no marked difference was found either between Ad-HIF transfected-hypoxia group and Ad-GFP transfected-hypoxia group or between Ad-HIF transfected-hypoxia group and Ad-HIF transfected-normoxia group. CONCLUSION: Higher HIF-1α expression is contributed to protective effects against hypoxic injury in HepG2 cells, the mechanisms of which may be correlated with promoting expression of gene regulated by HIF-1 and restraining over-expression of injure factors.

Objective To investigate the nutrition statuses of thiamine and riboflavin and their relationship with the antioxidant capacity and blood glucose and lipids levels in the middle-aged and elderly. Methods Totally 314 subjects aged above 40 years old from communities in Shanghai were enrolled. The 3-day survey of 24-hour's diet recall was made to evaluate the daily nutrient intakes using a nutrition assessment software provided by CDC China. Thiamine and riboflavin levels were detected by urine load test. Fasting blood glucose ( FBG), total choles-terol (TC), triglyceride (TG), superoxide dismutase (SOD) activity and malondialdehyde (MDA) were deter-mined by commercial kits. Results The average daily intakes of thiamine and riboflavin were (0. 82 + 0. 36) and (0. 91 +0.48) rag, respectively. The middle-aged and elderly whose intakes of thiamine and riboflavin reached recommended nutrient intake (RNI) level accounted for 11.8% and 17.2%, while those lower than 60% RNI ac-counted for 51.3% and 49. 4%, respectively. Urine load test showed the deficiency rates of thiamine and ribofla-vin were 65.0% and 58.6%, respectively. Compared with the normal group, plasma MDA, FBG, TC, and TG levels progressively increased and SOD activity decreased in insufficient and deficient groups; the plasma MDA, FBG, and TC levels were significantly different between normal group and thiamine deficient group ( P < 0. 05 ).The FBG and TC levels were negatively correlated with the status of thiamine ( r = - 0. 246, r = - 0. 154, P <0. 05). The MDA and TG levels were negatively correlated with the status of riboflavin ( r = - 0. 136, r =-0. 297, P <0. 05). Conclusions The nutrition statuses of thiamine and riboflavin are poor in the middle-aged and elderly in Shanghai. The nutritional statuses of thiamine and riboflavin are positively correlated with the antioxi- dant capacities and are negatively correlated with the level of FBG, TC, and TG.
