OBJECTIVE:To investigate the problems commonly occurred in outpatient prescriptions and to evaluate pharmacists’ role in the checking and intervention of prescriptions.METHODS:Questionable prescriptions recorded by outpatient pharmacists in their routine prescription checking from June,2004 to October, 2004 were classified and statistically analyzed. RESULTS:On average,the questionable prescriptions accounted for 0.35% of all the prescriptions dispensed by pharmacists. Of the questionable prescriptions,usage problems accounted for 43.0%,dosage accounted for 39.4%,volume dose accounted for 9.7%,frequency accounted for 2.7%.The results in prescribed frequency were significantly different before and after pharmacists intervention(P

Objective To establish a simultaneous determination method of cyclohexane,cyclohexanone and cyclohexanol in workplace air. Methods To collect the cyclohexane,cyclohexanone and cyclohexanol from the workplace air by pumping the air through the active carbon tube,resolve them with alcohol and then test the content of them by capillary gas chromatography. Results It was proved that these samples were separated effectively. The final measurement range of cyclohexane,cyclohexanone and cyclohexanol was 30-1 000 ?g/ml,20-1 000 ?g/ml and 20-880 ?g/ml respectively,the linear equation was y=257.4x+987.1 (r=0.999 9),y=239.9x+664.6 (r=0.9999 ) and y=192.4x+607.1 (r=0.999 9) respectively,the detection limit of was 1.5 ?g/ml,0.5 ?g/ml and 1.0 ?g/ml respectively. The minimum detectable concentration was 1.0 mg/m3,0.3 mg/m3 and 0.7 mg/m3 respectively (collected 1.5 L air sample). The efficiency of resolution was 90.1%,91.2% and 93.1% respectively. Conclusion The method is suitable for the simultaneous determination of the cyclohexane,cyclohexanone and cyclohexanol in the workplace air.

Objective To compare the efficacy between microwave endometrial ablation(MEA) and abdominal hysterectomy(AH) in the treatment of abnormal uterine bleeding(AUB).Methods A total of 80 patients with AUB was divided into two groups,either receiving MEA(40 patients) or receiving AH(40 patients).The clinical efficacy,operation time,intraoperative blood loss,white blood cell(WBC) count,and neutrophil granulocyte rate(NGR) before and after operation were compared.Results The effective rate for abnormal uterine bleeding was not significantly different between MEA(97.5%,39/40) and AH(100%,40/40)(?2=0.000,P=1.000).As compared with AH,MEA was characterized by a shorter operation time(4.8?1.2 min vs 102.5?34.6 min;t=17.848,P=0.000) and less intraoperative blood loss(0 ml vs 138.3?40.6 ml;t=21.544,P=0.000).Conclusions Microwave endometrial ablation is a novel and efficient minimally invasive method for abnormal uterine bleeding.

Objective To investigate the effects of parecoxib pretreatment on the intrapulmonary shunt during one-lung ventilation in patients undergoing esophageal cancer resection.Methods Forty ASA Ⅰ or Ⅱ patients of both sexes,aged 25-64 yr,weighing 45-70 kg,with body height 156-178 cm,undergoing elective esophageal surgery,were randomly divided into 2 groups (n =20 each):normal saline group (group NS) and parecoxib group (group P).Parecoxib 40 mg (in normal saline 10 ml) was injected intravenously 30 min before anesthesia in group P,while the equal volume of normal saline was given instead of parecoxib in group NS.Anesthesia was induced with iv injection of propofol,fentanyl and rocuronium.Bronchial blocker was inserted after tracheal intubation and the correct position was confirmed by bronchoscopy.Anesthesia was maintained with iv infusion of propofol and remifentanil and intermittent iv boluses of atracurium.HR,MAP,SpO2 and mean airway pressure (Pmean)were determined at 5 min of two-lung ventilation,at 40 min of one-lung ventilation,and at 30 min after re-expansion of the collapsed lung (T0-2).Blood samples were taken simultaneously from jugular vein and radial artery for blood gas analysis.Intrapulmonary shunt (Qs/Qt) was calculated.Results There were no significant differences in hemodynamic parameters and Pmean between the two groups (P ＞ 0.05).PaO2 was significantly lower,while Qs/Qt was significantly higher at T1,2 than at T0 in groups NS and P (P ＜ 0.05).PaO2 was significantly higher,while Qs/Qt was significantly lower at T2 than at T1 in groups NS and P (P ＜ 0.05).Qs/Qt was significantly lower at T1,2 and PaO2 was significantly higher at T2 in group P than in group NS (P ＜ 0.05).Conclusion Parecoxib 40 mg injected intravenously at 30 min before anesthesia can reduce the intrapulmonary shunt during one lung ventilation in patients undergoing esophageal cancer resection.

Objective To investigate the effect of different investing materials on the complete denture flasking deformation.Methods The denture wax casts were invested by plaster,dental stone,and dental stone together with silicone,respectively.8 trial dentures were randomly chosen from above each group,and 4 reference points were selected in the cast.The conventional water bath polymerization system was used for the process.The distance between reference points were measured before and after thermally processing the Acrylic base.F test and Kruskal-Wallis H test were applied for statistical analysis.Results The distance between A and B (F =3.768,P =0.040) and the mean of total distance among O,A,B and C(F =4.830,P =0.019) had statistically significant differences among the three groups.The deformation variance of Group 1 (a conventional plaster) between 175μm and 267μm was maximum.The deformation values of Group2 (a dental stone) was appropriate with Group3 (a dental stone + a silicone).Smoothness (x2 =17.575,P ＜ 0.01) was statistically different among the three groups.Conclusion The flaskingprocess with the plaster had the maximum movement.The process with dental stone showed the minimal toothmovement,the process with the dental stone along with with thesilicone caused a similar movement as from the single dental stone but resulted in a smoother denture surface.

[Objective]To study cervical hollow threaded autograft cortical bone fixator with morselized bone for cervical anterior interbody fusion.[Method] Eighteen sheep were underwent cervical anterior discectomy and fusion with a hollow threaded and fenestrated tibial cortical hone fixator filled with morselized bone(diameter of 300～500 um) for C5、6 or autogenous iliac crest bone cylinder or C3、4 respectively.Cervical spines were radiographed immediately after surgery and 1,2,3 months later,the specimens of C5～6 and C3～4 were taken for histology investigation and biomechanical test respectively.[Result] Interbody fusion was achieved 3 months after surgery in experimental gronp and all but one in control group,with statisticdly significant difference was found between two groups in biomechanical compression and torsion tests of ante or post-fatigue test(P
