Objective:To analyze and discuss the factors of seizure induced by imipenem/cilastatin.Method: The reports of seizure induced by imipenem/cilastatin from CBMDisc(1971-2006)and CHKD(1994-2006)were re- viewed and analyzed with Excel.Result:28 cases of seizure induced by imipenem/cilastatin were collected,including 20 men and 8 women with the principal primary respiratory infection with an average age of 66.5.Seizure occurred as early as 10 min.after the medication,and occurred latest in the fourth day of the medication.22 cases showed grand mal seizure and 6,partial seizure with a duration ranging from 20s to 30min and with a frequency of eight seizures.18 cases discontin- ued the administration,and 8 cases took lower daily dosage,in which some were given antiepileptic drugs or other adjunc- tive therapy,and 2 cases were not treated at all.All the cases recovered and were discharged from hospital except one who died from his circulation failure and respiration failure.The cause-effect relations of the relevance evaluation of seizures e- yoked by imipenem/cilastatin were as follows:1 sure case,26 probable cases,and 1 possible case.Conclusion:Seizure can be induced by imipenem/cilastatin,Owhich should be rationally used.More attention should be paid in clinic so as to ensure a safe medication.

OBJECTIVE:To facilitate a high performance operation of drug supply chain so as to provide satisfactory service for patients,the common terminal customers.METHODS:The principle of customer demand driven in drug supply chain and the significance of customer demand driven in drug supply chain management as well as the role hospitals played in the practice of the customer demand driven-based drug supply chain management were analyzed and qualitatively described.RESULTS & CONCLUSIONS:In the environment of buyers' market of drugs,as the terminal customers' envoy plenipotentiary and the best valuable clients in the drug market,hospitals play a key role in back driving drug supply chain's high performance operation.

AIM: To recognize the importance of ADR monitoring of drugs available on the market from PPA Event. MET- HODS: With reviewing relevant literatures and scanning relevant network stations. we summarlzed the importance of moni- toring ADR of drugs available on the market and signiticance of creating a perfect evaluation mechanisms and systems of ADR monitoring for those drugs. and analysed several method of ADR monitoring and points for attention Finally. we gave several suggestions about enhancing ADR monitoring .RESULTS& CONCLUSION:ADR events can be effectively pre- vented by perfect evaluation mechanisms and ADR monitoring systems of drugs available on the market.

OBJECTIVE:To study the method of preparing PEG-SOD enteric-coated capsuls and quality standard.ME_ THODS:Orthogonal design was used to select the optimal conditions for preparing PEG-SOD enteric-coated capsuls and the relevant quality standard of PEG-SOD enteric-coated capsuls was established according to the China Pharmacopoeia(2000). RESULTS:The optimal conditions were as follows:the content of PEG-SOD per capsule was40000IU;the weight ratio of stabilizer lactose was2.5%;filler was carboxymethyl starch;drying process was at60℃for20min.The preparation was ac?corded with the relevant quality standard.CONCLUSION:The technic of preparation is feasible,the method of quality control is reliable and the quality of preparation is stable.

Objective To screen and clone the genes related to stilbene glucosides biosynthesis in Polygonum multiflorum Thunb. Methods The differentially expressed genes in the root, stem and leaf of Polygonum multiflorum which have different contents of stilbene glucosides were screened by differential display reverse transcription polymerase chain reaction (DDRT-PCR). After pMD19-T carrier was inserted into the obtained differential genes for sequencing and comparison, the gene function was analyzed. Results Fifty-one differentially expressed cDNA fragments were found. Of them, 9 were used for the identification by semi-quantitative PCR. The identification results presented 3 positive fragments, one fragment was specifically expressed in the stem and leaf of Polygon-um multiflorum Thunb., sharing high homology with glycine dehydrogenase, and 2 were specifically expressed in the root of Polygonum multiflorum Thunb., having high homology with enoyl-CoA hydratase and aminopeptidase N, respectively. Conclusion Three homologous gene sequences obtained through DDRT-PCR provide a basis for the further study of biosynthetic pathway of stilbene glucoside from Polygonum multiflorum Thunb..

OBJECTIVE:To establish a simple method for calculating the optimal pharmacokinetic-equation parameters in drugs by intravenous administration using Excel programming solution.METHODS:The pharmacokinetic parameters and compartment model parameters after intravenous injection drugs were computed by means of Excel programming solution,and the results were compared with those computed by DAS method or residual method.RESULTS:By means of Excel programming solution,the optimal pharmacokinetic parameters of one-and two-compartment models were obtained,which were completely in line with those computed by DAS program.CONCLUSION:Excel programming solution is applicable for the computation of the pharmacokinetic parameters of one-and two-compartment models following intravenous injection drugs.

OBJECTIVE:To calculate pharmacokinetic parameters and compartment model's parameters by extravascular administration based on Excel function.METHODS:The parameters of pharmacokinetics and compartment model were calculated using residual method and Excel function.RESULTS:Excel can be used to directly demonstrate calculation process of parameters of pharmacokinetics and compartment model,with calculation results in line with those stated in textbooks.CONC-LUSION:The established method is simple,direct-viewing,reliable and easy to be extended,and it can be used to calculate pharmacokinetic parameters in clinical teaching or experiments.

OBJECTIVE:To evaluate the3pharmacotherapeutic schemes for biliary tract infections by pharmacoeconomic method.METHODS:Scheme A:cefazolin+metronidazole;Scheme B:ampicillin+gentamicin+metronidazole;Scheme C:lome?floxacin injection+metronidazole.These three schemes were retrospectively analysed with cost-effectiveness analy?sis.RESULTS:Scheme C had the lowest cost-effectiveness ratio with the highest total effective rate.CONCLUSION:Scheme C is the best one.

Objective To investigate the regulation of metabolic characteristics of metronidazole and tinidazole in human bile,and provide a theoretic basis for physician selecting antibiotic rationally when biliary tract was infected.Methods Samples of hman bile were obtained by ERCP plus ENBD,contents of metronidazole and tinidazole were simultaneously measured by HPLC method in the human bile and plasma.Results 0 25 hour after metronidazole and tinidazole were given through iv,contents of two antibiotics had reached the effective bactericida.Concentraction,content of tinidazole in the bile was relatively stable,but its C max was lower as compared with the metronidazole,contents of the two antibiotics in bile were continuously higher than those of the effective bactericidal in 24 hours,and after 16 hours and re-raise was observed in contents of the two antibiotics in bile.Conclusion As maintaining a higher concentration level for long time in the bile by iv,metronidazole and tinidazole were recommended in the patients with an infection in biliary truct.

The hospital is a dynamic, discrete, flexible, open and complicated system. The paper offered an analysis of the hospital system from the Wuli-Shili-Renli perspective, simplifying the complex process of medical activities into a clear-cut diagram of the system architecture. It also gave an account of the construction of a simulation model of specialized knowledge in hospital management by means of KBS, with the integration of the Wuli-Shili-Renli ideology into the KBS, and expounded the significance of Renli in the model of hospital management.
