RESUMEN
Objective To study comparatively the clinical anaesthetic potency and adverse effects to children of 0.375% ropivacaine used for brachial plexus block in upper-limb paediatric surgery.Methods After undergoing basal anesthesia with ketamine,36 children scheduled for hand and forearm surgery were randomly allocated to receive brachial plexus block with 0.375% ropivacaine(group A) and to receive intravenous anesthesia with ketamine(group B).The effect of sensor block and motor block,the changes of vital sings,the occurrence of side effect(nausea and vomiting) and palinesthesia of children were observed.Results The patients in group A kept a steady vital signs,their blood pressure,cardiac and respiration rate were similar to the backgroud level before anesthesia,whereas in group B the blood pressure,cardiac and respiration rate of patients were increased and kept a rather higer level,fluctuated with the depth of anesthesia.Conclusion Ropivacaine used for brachial plexus block in upper-limb paediatric surgery is a simple,feasible,and safe method with anesthetized perfectly and less complication.

RESUMEN
OBJECTIVE:To investigate the pharmacokinetic profiles of baicalin(a constituent in Sanhuang decoction) in rats.METHODS:Blood samples were collected as schedule from rats after intragastrically administration of Sanhuang decoction, then the content of baicalin was determined by HPLC and the chief pharmacokinetic parameters were computed.RE SU1TS:The chief pharmacokinetic parameters of baicalin in rats were as follows:t_(max1)=(15?4.23) min;t_(max2)=(6.8?0.54) h;C_(max1) =(4.49?1.56)?g?mL~(-1);C_(max2)=(3.25?1.23)?g?mL~(-1);AUC =(35.52?12.35)?g?h?mL ~(-1);t_(12)=(5.12?0.23)h;CL=(3.86?0.91) 1?h~(-1).CONCLUSION:The method is simple in sample treatment,rapid and accurate,specific and sensitive,and it can be used as a means for the monitoring of the serum concentration of baicalin containing Chinese patent medicines and so as to provide reference for clinical rational drug use.
RESUMEN
Objective Hotelling T2 Test was used to analyze the effect of sibutramine and to provide some information for new drug's exploration. Method Fifty-five patients with body mass index (BMI) over 25kg/m2 were selected according to generally accepted including and excluding criteria. The subjects were divided into 2 groups randomly. Control group was given placebo, and the experimental group were given sibutramine. Biological and biochemical indexes were examined pre-,during and post- clinical trial. Hotelling T2 test was used to compare the index mean vector of different phases. Results There were significant statistical differences between the two groups. (P
