Objective:To prepare a novel slow-releasing ketoconazole spraying membrane and to observe its effect on eczema and tinea corporis in guinea pigs.Methods: A novel ketoconazole spraying membrane was prepared with chitosan chlorhydrate as the membrane material.The contents of ketoconazole and desamethasone in the spraying membrane were assayed by HPLC.The separation was performed on Waters Symttry C_(18) column(250 mm?4.6 mm,5 ?m),with the mobile phase consisting methanol-potassium dihydrogen phosphate buffer(4∶1),at a flow rate of 0.6 ml/min.The dectection was carried out with a UV detector at 239 nm,at(22?2)℃.The quality criteria for the novel ketoconazole spraying membrane was established.The curative effect of the ketoconazole spraying membrane on eczema and tinea corporis was observed in guinea pigs and was compared with those of spraying membrane matrix,desamethasone antipruritics cream and compound ketoconazole cream.Results: The calibration curves of ketoconazole and desamethasone were linear between 0.2-2.0 mg?ml~(-1)and 0.02-0.20 mg?ml~(-1),respectively;the recoveries for ketoconazole and desamethasone were 98.41% and 97.84%,respectively.The intra-day and extra-day RSDs for ketoconazole were(1.17%) and 1.26%,respectively,and for desamethasone were 1.57% and 1.40%,respectively.Stimulation test showed that the spraying membrane had no irritative effect on the skin of guinea pig.The novel ketoconazole spraying membrane had similar effect on eczema and tinea corporis as those of desamethasone antipruritics cream and compound ketoconazole cream.Conclusion: This novel ketoconazole spraying membrane is easy to prepare and has obvious therapeutic effects on eczema and tinea corporis in guinea pigs,making it favourable for containing combined agents.

OBJECTIVE: To prepare double-layer sustained release ornidazole films and investigate its release rate in vitro.METHODS: The double-layer sustained release ornidazole films film were prepared by the method of homogenate.The formula of the films were optimized by orthogonal experiment with the mass ratio of polyviol to CMC-Na(factor A),the total amount of polyviol and CMC-Na(B) and the amount of glycerol(C) as factors.The concentration of ornidazole was determined by ultraviolet spectrophotometry and its release rate was also computed.RESULTS: The double-layer sustained release film was well-shaped.The optimized formula of the film was as follows: factor A=1∶1,B=4.5 g,C=4.0 g.The standard curve of ornidazole was linear within a range of 1～20 ?g?mL-1(r=0.999 5,n=6),with an average recovery of 100.3%(RSD=1.3%,n=5).A continuous releasing of 11.0 hours was achieved for the prepared films and its cumulative release amount in vitro within 8 hours reached 81.50%.CONCLUSIONS: The preparative method of the films was simple,and the film had a slow-release property.

Objective To study the value of color Doppler ultrasound in diagnosis of deep vein thrombosis (DVT) of lower extremity and pulmonary embolism (PE) in spinal cord injury (SCI). Methods 60 PE patients (PE group) and 35 SCI patients without PE (control group) received color Doppler ultrasound examination for DVT of lower extremity. Results PE group included 36 SCI patients (PE-SCI group) and 24 no-SCI patients (PE-no-SCI group). There were 15 cases with lower extremity thrombosis in PE-SCI group, and 9 cases in PE-no-SCI group (P>0.05), while there were 5 cases in the control group. There was significantly different in lower extremity thrombosis between PE group and the control group (P<0.01). In PE group, the detection rate was not significantly different between acute PE (detected 11 cases out of 37 cases) and chronic PE (detected 10 cases out of 23 cases) (P>0.05). 31 cases were rechecked as lower extremity venous valve regurgitation and calf muscle vein dilation (51.7%) in PE group while 8 cases in the control group (22.9%) (P<0.01). Conclusion There is not significantly different in the detection rate of DVT of lower extremity in PE patients with and without spinal cord injury, which are higher than in the patients without PE. Color Doppler ultrasound is necessary to check DVT in acute and chronic PE patients.

The prescription of antibiotics for children with upper respiratory infections (URIs) in outpatient department of our hospital from November to December 2010 and from July to August 2011 were retrospectively analyzed.In 37 211 patient visits (prescriptions) with suppurative tonsillitis,laryngitis and other URIs,the antibiotic prescription rates were 90.45％ (3 626/4 009),78.77％ (2 642/3 354)and 52.25％ (15 596/29 848),respectively;the intravenous antibiotics rates were 78.22％ (3 136/4 009),60.58％ (2 032/3 354) and 16.47％ (4 915/29 848),respectively for above three conditions.For suppurative tonsillitis,the 3rd generation cephalosporins were the most commonly prescribed antibiotics (orally:51.07％,715/1 400) and(intravenously:54.88％,1 721/3 136),followed by the 2nd and first generation cephalosporins and macrolides.For laryngitis and other URIs,the 2nd generation cephalosporins were most frequently prescribed(orally:48.78％,538/1 103 and 39.16％,4 433/11 320,respectively) and (intravenously:54.38％,1 105/2 032 and 42.75％,2 101/4 915,respectively),followed by macrolides,3rd generation cephalosporins and first generation cephalosporins.No intravenous penicillin were prescribed.Oral penicillin were prescribed for 0-0.22％ of these children.The results indicate that antibiotics prescription rates are high for children with upper respiratory infections,particularly the prescription of broad spectrum antibiotics and intravenous antibiotics,while penicillin is seldom prescribed.

Objective To evaluate the intraoperative opioid?sparing effect of different duration transcutaneous electrical acupoint stimulation ( TEAS ) in video?assisted thoracoscopic lobectomy. Methods Seventy?five patients, aged 18-64 yr, weighing 40-96 kg, of ASA physical status Ⅰ or Ⅱ, scheduled for elective video?assisted thoracoscopic lobectomy under general anesthesia, were randomly divided into 3 groups (n=25 each) using a random number table: control group (group C), 30 min of stimulation before induction of anesthesia group ( group B) , and stimulation throughout surgery ( group T) . In group B, the patients received TEAS ( frequency 2∕100 Hz ) on acupoints Xinshu ( BL15 ) , Feishu (BL13), Neiguan (PC6), Hegu (LI4) on the operated side starting from 30 min before induction of anesthesia until the beginning of induction, and the intensity was the maximum current that could be tolerated. The intensity for Neiguan ( PC6) and Hegu ( LI4) was 6-12 mA, and for Xinshu ( BL15) and Feishu ( BL13 ) was 9-18 mA. In group T, the patients received TEAS on the four acupoints mentioned above starting from 30 min before induction of anesthesia until the end of surgery. The patients had the electrodes applied, but received no stimulation in group C. After anesthesia was induced with propofol?sufentanil?cisatracurium, double lumen endotracheal tube was inserted. Propofol was given by target?controlled infusion to maintain BIS value within the range of 40-60. Cisatracurium was infused continuously to facilitate muscle relaxation. The infusion rate of remifentanil was adjusted to maintain analgesia nociception index value within the range of 50-70. The intraoperative consumption of remifentanil ( the intraoperative consumption of sufentanil was converted to the consumption of remifentanil producing the equivalent effect by 1∶ 10) was recorded. Results Compared with group C, the intraoperative consumption of remifentanil was significantly decreased in B and T groups. The intraoperative consumption of remifentanil was significantly lower in group T than in group B. Conclusion TEAS on Xinshu ( BL15 ) , Feishu (BL13), Neiguan ( PC6) and Hegu acupoints throughout surgery and for 30 min before induction of anesthesia significantly reduces intraoperative opioid consumption in the patients undergoing video?assisted thoracoscopic lobectomy, while TEAS throughout surgery provides better effect.
