OBJECTIVE:To evaluate the3pharmacotherapeutic schemes for essential hypertension by pharmacoeconomic method.METHODS:143out-patients with essential hypertension were randomly divided into3groups:group A(n=47)re?ceived Losartan K50mg q.d.;group B(n=48)Captopril25mg b.i.d.;group C(n=48)Losartan K50mg q.d.+Hy?drochlorothiazide25mg q.d..All3groups were treated for4weeks and the effects and ADRs were observed,data was evaluated with the pharmacoeconomic cost-effectiveness analysis method.RESULTS:The effective rate of group C was markedly higher than those of other two groups(P0.05),and group C was also the lowest in C/E and?C/?E.CONCLUSION:Scheme C is the best one.

Objective The purpose of this study was to investigate the effect of isoflurane on baroreflex sensitivity ( BRS ) during induced hypotension and to illucidate the mechanism of isoflurane-induced hypotension. Methods Fifteen female ASA I or II patients aged 13-16 yrs undergoing scoliosis surgery were studied. The patients were unpremedicated. Radial artery and internal jugular vein were cannulated for BP and CVP monitoring. EGG, BP and SpO2 were continuously monitored before and during anesthesia. Anesthesia was induced with midazolam 0.04 mg? kg-1 , fentanyl 2 ?g? kg-1 and propofol 2 mg? kg-1 . Tracheal intubation was facilitated with rocuronium 1 mg?kg-1 . Anesthesia was maintained with isoflurane inhalation and fentanyl infusion (0.4?g?kg-1?h-1). Nitroglycerin (NTG) was infused at 1 ?g?kg-1 ?min-1 at the beginning of surgery to control MAP at 55-65 mm Hg and esmolol 20 mg was given i. v. to control HR 0.8. BRS was measured before induction of anesthesia (T1), immediately after intubation (T2), when end-tidal concentration of isoflurane reached 0.7% (T3 , supine) (T4 , prone), when end-tidal concentration of isoflurane reached 1.3% (T5) , at 30 min after NTG infusion and esmolal bolus injection were stopped (T6) when end-tidal concentration of isoflurane was decreased to 0.7 % (prone, T7 ) and immediately after the patients were turned supine (T8 ) . Results When end-tidal isoflurane concentration reached 1.6%, the desired level of hypotension could be maintained without NTG infusion and esmolol injection. BRS gradually decreased with increasing end-tidal isoflurane concentration. BRS was the lowest at 30 min after termination of NTG infusion and esmolol bolus injection. Conclusion Isoflurane depresses BRS and BRS depression may be involved in the mechanism of isoflurane-induced hypotension.

AIM: To study the effect of partial liquid ventilation on the ultrastructure of pulmonary surfactant(PS) system in endotoxin-induced acute lung injury METHODS: The effect of partial liquid ventilation on the ultrastructure of PS system in endotoxin-induced acute lung injury was observed with electronmicroscope histochemistry. RESULTS: There was ultrastructure impairment of PS system in endotoxin-induced acute lung injury, the pulmonary surfactant layer was discontinuous, lamellar bodies and plasmosomes in type Ⅱ pneumonocytes vacuolated, and a few of them were even necrotized and disrupted into the alveolar space. The pulmonary surfactant layer was still continuous, the vacuolation of lamellar bodies and plasmosomes in type Ⅱ pneumonocytes was little with partial liquid ventilation. CONCLUSION: Partial liquid ventilation can lessen the impairment of PS system in endotoxin-induced acute lung injury in rats.

Objective: To evaluate the effect of propofol on coronary circulation of acute myocardial ischemia-reperfusion inury. Metbod: 18 hybrid dogs (11-14kg) were divided randomly into three groups:NS group (normal saline, 2ml?kg~(-1)?h~(-1)), HP group (high-dose propofol, 11.2mg?kg~(-1)?h~(-1)), LP group (low-dose propofol, 5.6mg?kg~(-1) ?b~(-1)). These dogs were subjected to 90 min left anterior descending coronary artery (LAD) occlusions followed by 200 min of reperfusions. Before administration, 60 min after administration, 60min, 120min, 180min following reperfusion,coronary circulation was assessed by measurement of coronary perfusion pressure (CPP) and blood flow of LAD. Result: The values of CPP in HP and LP groups 60 minafter administration were significantly lower than those in NS group before LAD occlusion (P

Objective To investigate the effect of laparoscope combined with ureteroscope for the treatment of hepatolithus. Methods 98 patients were randomly divided into two groups:the study group(laparoscope combined with ureteroscope group) and the control group (the open surgery group). The mean blood loss, the recovery of the stomach and intestines function, hospital stay and the rate of complications were observed. Results Compared with the open surgery group,the mean blood loss,the recovery of the stomach and intestines function,and hospital stay in the study group had statistically significant difference (all P＜0. 05). Compared with the open surgery group, the time of surgery and the patients carryingT tubes in the study group had statistically significant difference (all P＜0. 05). Compared with the open surgery group, the rate of gallstone removal、the rate of gallstone residual and the rate of injures in the study group had no statistically significant difference(all P＞0. 05). Conclusion Laparoscope combined with ureteroscope in patients with hepatolithus had the advantage of less trauma, faster postoperative recovery and fewer complications. It was safe and effective,so it was worth to recommend its clinical use.

369 patients with hypertension living in Xietu community were randomized into 2 groups:intervention group receiving the group-interference-management and control group receiving routine hypertension management services.We found that patients in the intervention group had better self-management behaviors,self-efficacy and health status in comparison with the control group (P＜0.05).The systolic and diastolic blood pressure in the intervention group decreased more remarkably than that in the control group (P＜0.05).Our result suggested that the community-based hypertension group-interference-management model is more effective to control hypertension than the routine hypertension management services.

ObjectiveTo investigate current status and demand of continous general practice (GP) education in Shanghai.Methods Two hundred and twenty general practitioners from 10 community health service centers of Shanghai underwent a questionnaire survey.Chi-square test was used for data analysis.ResultsThe effective response rate was 96.57％(212/220).About 87 percent of the participants considered continous GP education was helpful.Nearly 55 percent of the participants were satisfied withcurrentcontinousGP education.Unsatisfaction withcontinuing GP education,wishto reparticipate continous GP education,expected method and content of training were partly related to professional title and age.Ninety-seven percent of the participants thought the assessment of continuous GP education should include clinical practical capability evaluation.Conclusion The present continous GP education in Shanghai is not matched with GP's demand.Continous GP education should meet different needs of general practioners in different ways.

【Objective】To explore a method for the establishment of animal model of coronary heart disease(CHD) with the blending of phlegm and blood stasis.【Methods】Methods of TCM-WM combination(traditional Chinese medicine integrated with western medicine) and disease-syndrome combination were used to establish a model.The model was evaluated by the changes of symptoms,signs and laboratory indexes and by the effect of blood-stasis-removing and phlegm-resolving herbs on the model.Sixty Wistar rats were randomized into normal group,model group,low-dose herbal medicine group and high-dose herbal medicine group.The normal group was fed with routine forage and normal saline,and the other three groups with high-fat forage and fat milk(10mL?kg~(-1)?d~(-1)).Low-and high-dose herbal medicine groups were given Xuefu Zhuyu Decoction combined with Gualou Xiebai Banxia Decoction in the dosages of 12 and 24 10g?kg~(-1)?d~(-1)respectively by gastric gavage,and the model group given the same volume of normal saline for 7 consecutive weeks.Coronary artery ligation was performed in the 35~(th) day.The changes of electrocardiogram(ECG) were observed before and after the modeling,and blood lipid,myocardial enzymes and hemorrheological parameters were determined.The heart weight was examined to calculate heart index.【Results】ECG in the model group indicated severe myocardial ischemia,which may be relieved by herbal medicine.Serum contents of cholesteril,tryglyceride and creatine kinase(CK),whole blood viscosity,hematocrit and heart index were obviously increased in the model group,while the above indexes decreased to different degrees in herbal medicine groups (P
