OBJECTIVE:To prepare triptolide-loaded sustained release microspheres and investigate its release profile in vivo and in vitro.METHODS:Triptolide-loaded sustained release microspheres were prepared by solvent evaporation method.A motionless method was used to investigate the process of release in vitro.The in vivo release process was investigated by pharmacokinetic experiment in rats.RESULTS:The microspheres were round and smooth examined by optical microscope.The size of triptolide loaded microspheres was(38.2?1.7) ?m and the encapsulation efficiency of triptolide loaded microspheres was(74.7?3.2)%.A constant in vitro release of triptolide-loaded microspheres was noted.The pharmacokinetic parameters of microspheres in vivo were as follows:Cmax was(114.7?31.90) ng?mL-1;tmax was(8.32?4.43) h;AUC was(1 774 282?1 046 152) ng?h?mL-1 and MRT was(596?165) h.In addition,the in vivo-in vitro correlation was good,r=0.955 3(P

OBJECTIVE:To investigate the situation of drug use and occurrence of side effects of drug interactions in the inpatients with chronic obstructive pulmonary disease(COPD).METHODS:54 medical charts of the inpatients in the First Affiliated Hospital of Tsinghua University diagnosed as having COPD from Oct.2006 to Feb.2007 were randomly collected for analyses of patients' basic information drug utilization.RESULTS:The COPD patients received more than 8 kinds of drugs simultaneously in more then 20% of their hospital days.Side effects of drug interaction occurred in 70% of them.CONCLUSION:The study shows that the drug use in the COPD inpatients is characterized by excessive drug kinds and high incidences of drug interactions,therefore,it is urgent to take further intervention measures on drug use in COPD inpatients.

OBJECTIVE:To develop a simple micellar electrokinetic capillary chromatography for determination of theophylline concentration in human plasma. METHODS: The determination of plasma sample(without any pretreatment) was performed on un-coated fused-silica capillaries (at an effective length of 21 cm) in which the cathodic buffer solution (solution A) was 15 mmol?L-1 borax(pH=10) and the running buffer solution(solution B) was sodium dodecyl sufate (SDS)(200 mmol?L-1) -contained solution A. The sample was injected into capillary by pressure with separation voltage of 12 kV;the UV detection wavelength was set at 280 nm;quantitation was performed by external standard peak area method. RESULTS: The average determination time of each sample was 11 min;the linear range of theophylline was 1.25～40 ?g?mL-1 with its lowest detectable limit at 0.5 ?g?mL-1;the average methodological recovery was 90.33%(RSD=2.51%);the intra-day RSD was 2.34%～3.36% and the inter-day RSD was 2.03%～6.51%,respectively. CONCLUSION: The developed method is simple,rapid and sensitive and it is applicable for the therapeutic drug monitoring of theophylline.

OBJECTIVE:To discuss the best hospital online purchase mode.METHODS:3 modes of online purchase were compared in the way of graphic and grid illustrations by referring to relevant literature and evaluating our own experience.RESULTS:Each online purchase mode has its own special characteristics,and hospitals can make their decisions according to the information capacity of themselves and their information system suppliers.CONCLUSION:Online purchase modes are more advantageous than traditional modes,so it should be applied widely.

AIM: To evaluate the efficacy and safety of neurotropin in the treatment of neuropathic pain.METHODS: A systematic literature search was performed in biomedical database including MEDLINE,EMBASE, Cochrane Central Register of Controlled Trials, CBM and CNKI. All studies focused on the clinical controlled trials, especially randomized controlled trials (RCTs) . The outcome measures included efficacy,life quality, cost of the treatment and adverse reactions. Quality assessments of clinical trials were evaluated with Jadad Score. Meta-analysis of included studies was performed with Revman software. RESULTS: Twenty-six clinical trials were included. Jadad Score of 24 trials was less than 3, which indicated the poor quality of the trials. None of the clinical trials evaluated the changes in life quality and cost related to neurotropin treatment.Meta analysis of 11 trials indicated neurotropin was more effective than placebo or blank, and the odds ratio of efficacy was 3.84 [2.68, 5.50] . The combining effect of 6 RCTs showed that neurotropin decreased the pain scores measured by Visual Analog Scale significantly compared with placebo or blank, the weighted mean difference (WMD) was -1.76 [-2.31, -1.21] . The pooled effects of the trials comparing neurotropin with other pain relieving drugs such as earbamazepine or NSAIDs also showed positive effect favored neurotropin.Neurotropin had no more adverse reactions than placebo, carbamazepine or NSAIDs, and the pooled risk difference was -0.01 [-0.04, 0.02] . CONCLUSION: According to present evidence, neurotropin may be effective and safe in the treatment of neuropathic pain. However, the poor quality of the studies decreases the persuasion of the results. Large-scale and well-designed RCTs with enough follow-ups should be carried out to provide further evidence for the use of neurotropin in neuropathie pain.
