Objective To investigate the distribution of the bacteria in ascites of spontaneous bacterial peritonitis (SBP), and to find out the resistance of the bacteria to antibacterial agents. Methods 44 inpatients from 1999 to 2003 with SBP and positive bacterial culture in ascites were selected, and the bacterial distribution, resistance to drugs and the application of antibacterial agents were analyzed. Results 88.6% (39/44) of the 44 isolations were gram-negative bacillus, among them 28 isolations were E. coli. The results of drug sensitive test revealed that 90% of E. coli, Aeromonas sobria, Klebsiella pneumoniae were sensitive to the third generation of cephalosporin. The resistant rate of E. coli to cefotriaxone and cefotaxime were 11.54% and 12.50%, respectively. Conclusion The third generation of cephalosporin was the experiential selection in treating SBP before getting the report of drug sensitive test. Anti-bacterial agents combined with ?-lactamase inhibitors may be used in treating some severe cases.

Objective To observe the clinical efficacy and the economic effectiveness of different therapeutic schemes for Chronic hepatitis UB.Methods Patients with Chronic Hepatitis B were treated by using different drugs:Interferon ?1b(group A),Lamivudine(group B),Interferon ?1b combination with Lamivudine(group C),Interferon ?1b combination with thymotentin(group D),Interferon ?1b combination with thymosin alphal(group E).Evaluation was carried out with pharmacoeconomic cost-effectiveness.Results At the end of therapy,the clearance rate of serum HbeAg was lowest in group B(10 94%),the other groups were more than 50%.The clearance rate of serum HBV-DNA was higher in group B and C than in the other groups,it was 85 94%,87 93% respectively.Normalizing ALT values was higher in group C,group D and group E than in group A and group B.The costs of several therapeutic schemes were RMB 8156 7(group A),6935(group B),15091 7(group C),26033 4(group D) and 89978 4(group E) yuans,respectively.Conclusions According to the evaluation with pharmacoeconomic cost-effectiveness analysis,the therapeutic scheme of Interferon ?1b,Lamivudine and Interferon ?1b combination with Lamivudine is best one for treating chronic hepatitsi B,in this groups,Interferon ?1b combination with Lamivudine was better than the other two groups.

OBJECTIVE:To evaluate the cost and effectiveness of three pharmacotherapeutic schemes for hemorrhage of upper digestive tract caused by liver cirrhosis.METHODS:132 patients with hemorrhage of upper digestive tract were treated by different drugs:octreotide(49),somatostatin(42),pituitrin(41).Evaluation was carried out with pharmacoeconomic cost-ef_fectiveness analysis.RESULTS:The hemostatic rates of octreotide,somatostatin and pituitrin for rupture of esophageal varicosis were 88.89%,80% and 46.15%;for peptic ulcer bleeding associated with liver cirrhosis 88.89%,87.50% and 50.00% and for hemorrhage from acute gastric mucosa erosion combined with liver cirrhosis 100.00%,94.44% and 68.18%,respectively.The costs of octreotide,somatostatin and pituitrin schemes were RMB 2 242.8,3 294 and 996.2 yuans,respectively.CONCLU_SION:According to the evaluation with pharmacoeconomic cost-effectiveness analysis,the therapeutic scheme of pituitrin seems to be the best one for treating hemorrhage of upper digestive tract resulting from liver cirrhosis.

Objective: To establish the fingerprint chromatogram of Tongguanteng Injection (caulis Marsdeniae Tenacissimae). Methods: HPLC with ZORBAX SB C 18 column was used, the (a) 0.05% H 3PO 4 H 2O and (b) ACN 0.05% H 3PO 4 H 2O (13∶87) (gradient elution) as a mobile phase and detection wavelength at 254nm. Results: 22 peaks were indicated on the HPLC fingerprint of Tongguanteng Injection. The relative retention time and relative peak area were obtained with itself peak at retention time 48.5 min. Conclusion: The method is simple and accurate with a good reproducibility and can be used as a quality control method for Tongguantent Injection.

OBJECTIVE To study the pharmacokinetics of omeprazole (OME) in 8 patients with liver cirrhosis.METHODS The plasma concentrations of OME were determined by HPLC,and the pharmacokinetic parameters were computed by using 3P97 program.RESULTS The plasma concentration versus time curve following intravenous 40 mg OME in patients with liver cirrhosis was coincident with two-compartment model.The elimination half-life was (3.34±0.38) h,which was longer than the value of the healthy volunteers and CLs was lower than the value of the healthy volunteers.CONCLUSION The dosage of OME may be given in the half of the routine dosage or adjusted conditionally when using for the patients with liver cirrhosis.
