OBJECTIVE:To establish a HPLC-fluorescence detection method for the determiniation of the serum concentration of metoprolol.METHODS:The determination was performed on Symmetry C18 column,and the mobile phase consisted of acetonitrile-water-triethylamine -phosphoric acid(110∶390∶2.5∶1.6) at a flow rate of 0.8 mL?min-1.The excitation wavelength was 265 nm and the emission wavelength 298 nm,and the sample size was 20 ?L.RESULTS:Good linearity was obtained for metoprolol over the range of 2.0～100.0 ?g?L-1 with correlation coefficient r=0.999 6.At low,medium and high concentrations,the average recoveries of metoprolol were 99.73%,98.21% and 99.38%,respectively.The intra-day RSD were 2.89%,2.36% and 1.32%,respectively,and the inter-day RSD were 3.73%,3.03% and 2.25% respectively.The lowest detectable limit was 1.0 ?g?L-1.CONCLUSION:This method is precise,accurate,specific,simple yet with high recovery,and it is applicable for clinical monitoring of blood concentration and pharmacokinetic study.

Objective To investigate the clinical efficacy of Zusanli moxibustion intervention in abdominal distention with enteral nutrition after stomach cancer surgery.Methods One hundred patients who had undergone stomach cancer surgery and received postoperative enteral nutrition were randomly allocated to treatment and control groups, 50 cases each. The control group received medication and the treatment group, Zusanli moxibustion in addition. Post-treatment incidences and grading scores of abdominal distention were compared between the two groups.Results The incidence of abdominal distention was 6.0% in the treatment group and 24.0% in the control group; there was a statistically significant difference between the two groups (P<0.05). The grading score of abdominal distention was (0.33±0.58) in the treatment group and (0.92±1.00) in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Zusanli moxibustion can effectively prevent the occurrence of abdominal distention in patients with enteral nutrition after stomach cancer surgery.

AIM: To study the effect of the processing on the contents of nuciferine and quercetin existed in lotus leaf(Nelumbo nucifera Gaertn).METHODS: Nuciferine and quercetin were allowed for the markers and its contents were assayed by HPLC.Marker constituents were compared among raw herb,carbonizing by stir-frying and carbonizing by calcining.RESULTS: By means of carbonizing processing,nucifering content of lotus leaf reduced to 99.25% and 99.23% compared with the unprocessed lotus leaf,quercetin content of lotus leaf increased to 608.56% and 643.85% compared with the unprocessed lotus leaf.CONCLUSION: The heating processing has remarkable effect on the contents of nuciferine and quercetin in Nelumbo nucifera Gaertn.

Objective To study the antimicrobial resistance changes of common pathogenic bacterial isolates in Guangzhou. Methods Disc diffusion test was used to measure the antibiotic susceptibility of 5063 strains collected from 13 hospitals in Guangzhou from 1998 to 2000 (Fastidious bacteria were detected by E test). Results From 1998 to 2000, the percentage of methicillin resistant Staphylococcus aureus was 45.3%,53.0%, and 50.8%, respectively, and that of methicillin resistant coagulase negative Staphylococcus was 64.1%, 86.0%, and 79.0% accordingly. There was no resistance to vancomycin in the strains of Staphyloccocas and there were 40.7%, 31.8% and 36.4% in E.coli and 43.1%, 42.7%, and 31.5% in Klebsiella found to be extended spectrum lactamases producing in the 3 years. Resistant rates of Enterobacter spp against the third generation cephalosporins increased. Resistant rates of P.aeruginosa against cefoperazone/sulbactam, ceftazidime,amikacin were changed unmarkedly in recent years. Conclusions The antimicrobial resistance of common pathogenic bacteria is serious in Guangzhou area. The surveillance of antimicrobial susceptibility is of great significance.

Objective To shorten the time of drug reception for ward areas and improve the overall satisfaction level towards the hospital. Methods The process of drug reception for ward areas was optimized by means of information technology and through business process reengineering. Results The time of drug reception for ward areas was effectively shortened and work efficiency and the overall satisfaction level were improved. Conclusion Using information technology and implementing business process reengineering are effective measures that can be taken by hospitals to improve efficiency and satisfaction level.

Under the principle of giving priority to patient care, efforts were made to expand the functions of HIS in the dispensary of the ward areas. Using HIS to automatically create and print drug-dispensing labels that fit in with clinical needs and thus realizing paperless dispensation in the dispensary of the ward areas could not only reduce errors but also improve work efficiency and service quality. Medication records created automatically with HIS, in the process of which clinical data were automatically entered, were easy to use and provided complete and timely information, thus setting up a sound platform ofr the delivery of pharmaceutical service. A quantitative system for personnel appraisal and control was also established. Hence the enhancement of work efficiency and control level.

Objective:To establish a method of ion chromatography for the determination of sodium, potassium and citric acid in potassium sodium hydrogen citrate granule. Methods:The chromatographic conditions for potassium and sodium were as follows:a Di-onex IonPac CS12A column (250 mm × 4. 6 mm, 5μm), 0. 02 mol·L-1 methane sulfonic acid solution as the mobile phase, the flow rate of 1. 0 ml·min-1 , the suppressor of CSRS 300, the inhibition current of 59 mA, the inhibition type conductivity detector, and the injection volume of 25 μl.
