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.

heart.CONCLUSION:The half-life of PEG-SOD enteric coated capsules is much longer than that of SOD enteric coated capsule and is worth further studying as a new type preparation

A rapid and sensitive liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) method for quantification of sitagliptin in human plasma and urine had been developed. This method was applied to the pharmacokinetics study of sitagliptin tablet after single- and multiple-dosing in Chinese population. Plasma samples were prepared by a liquid-liquid extracted method, and urine samples were diluted. Compounds were analyzed by multiple reaction monitoring (MRM) mode with a electrospray ionization (ESI) interface. Mobile phase consisted of methanol and water (85 : 15, v/v). The linear concentration range of calibration curve was 0.5-1 000 ng.mL-1. and 0.2-100 µg.mL , intra-run/between-run accuracy was 98.98%-103.69% and 97.63%-102.29%, intra-run/between-run precision was <5.51% and 4.26% for plasma and urine sample, respectively. The stability of sitagliptin stock solution was tested for 55 days at -30 °C. Sitagliptin was stable when stored under the following conditions: 24 hours in the autosampler after sample preparation; 24 hours at room temperature, after 3 freeze and thaw cycles (from -30 °C to room temperature), 40 days at -30 °C for plasma and urine samples. The absolute recovery in plasma was 71.1%, and no matrix effect was founded. This method was proved simple, specific, sensitive, rapid and suitable for pharmacokinetics study of sitagliptin in human being.

Objective To discuss the influence of different doses budesonide aerosol inhalation on serum cytokines levels in children with severe asthma.Methods 96 children with severe asthma aged 4 to 14 years old in our hospital were chosen,and they were randomly divided into the observation group and the control group,48 cases in each group.All patients were given conventional treatment, and the control group was given 1mg/time budesonide treatment on the basis of conventional treatment (3 times a day),while the observation group was given 2mg/time budesonide treatment (3 times a day).Before and 1 week after treatment,the clinical symptoms of two groups were observed and compared,as well as the changes of IL-4,IFN-gamma,IL-10 and TNF-α.Results In the obser-vation group,wheezes,coughing,wheezy sound and rales disappearance time were (2.10 ±0.77)d,(5.45 ±1.20)d, (3.46 ±1.03)d,(5.55 ±1.35),which were significantly shorter than (2.98 ±1.02)d,(7.48 ±1.19)d,(5.43 ± 1.06)d,(7.56 ±1.67)d in the control group (t=4.77,8.32,9.23 and 8.32,all P<0.01).4 weeks after treat-ment,the total effective rate of the observation group was 89.6%,which was significantly higher than 72.9% of the control group (χ2 =4.376,P<0.05).After treatment,the IL-4,IL-10,TNF-alpha,IFN-gamma levels in the observation group were (4.06 ±1.77)pg/mL,(12.77 ±2.05)pg/mL,(4.15 ±1.11)ng/mL,(26.23 ±2.78)pg/mL, which had significant changes compared with (9.02 ±2.23)pg/mL,(10.21 ±1.30)ng/mL,(6.66 ±1.62)pg/mL, (17.33 ±2.31)pg/mL before treatment(t=12.07,24.56,16.20,17.25,all P<0.01).After treatment,the IL-4, IL-10,TNF-alpha,IFN-gamma levels in the control group were (9.11 ±2.05)pg/mL,(6.80 ±1.23)ng/mL, (9.88 ±2.20)pg/mL,(21.22 ±2.80)pg/mL,which had significant changes compared with (9.11 ±2.05)pg/mL, (10.38 ±1.37) ng/mL,(6.71 ±1.77) pg/mL,(17.30 ±2.05) pg/mL before treatment( t=5.36,13.47,7.77, 7.83,all P<0.01).But IL-4,TNF-alpha levels in the treatment group were significantly lower than those in the control group (t=7.32,11.08,all P<0.01),while IL-10 and IFN-gamma levels were significantly higher than those in the control group (t=6.65,8.80,all P<0.01).The incidence of adverse reactions of the two groups had no statistically significant difference (χ2 =0.771,P>0.771).Conclusion High doses of budesonide aerosol inhalation in the treatment of children with severe asthma has obvious clinical curative effects,which could significantly improve the patients'clinical symptoms,and also has low incidence of adverse reactions,which is worthy of clinical promotion.

OBJECTIVE: To implement scientific drug control in inpatient dispensary by means of “Army No.1” system and to establish digitalized drug quality control system. METHODS: The “Army No.1” network system was put into wide operation in our hospital to establish interconnection among doctor workstation, nurse workstation and pharmacy workstation. Hence, the central dispensing mode was established. RESULTS: The operation of Army No.1 system not only relieved the workload of both clinic and pharmacy, increased whose working efficiency and transparency but also reduced overstock and run-off of drugs and enforced drug monitoring; meanwhile it facilitate the carrying out of pharmaceutical care and evaluation of drug utilization. CONCLUSIONS: Central dispensing mode in inpatient dispensary drug control by means of “Army No.1” system is advisable and which deserves generalization.
