Objective To compare the effects of butorphanol,midazolam and innovar on relieving appendix traction response during appendectomy. Methods Sixty-eight patients who underwent appendectomy were randomly divided into butorphanol group(n=21),midazolam group(n=23) and innovar group(n=24).Butorphanol,midazolam and innovar were intravenously administered to patients during skin incision.The appendix traction response,sedation score,heart rate(HR),mean arterial pressure(MAP) and pulse oxygen saturation(SpO2) were recorded and compared among groups.Results Compared with those before operation,there was no significant changes in HR,MAP and SpO2 during operation.The effective rates of butorphanol,midazolam and innovar in relieving appendix traction response were 95.2%,65.2% and 50.0%,respectively.Butorphanol surpassed midazolam and innovar in sedation and relieving appendix traction response(P

A new ionizing-radiation resistant strain WGR702 was isolated from arid soils which had been ra-diated. The strain WGR702 was Gram-positive and coccus, the diameter of the cell was 1.5 ?m～2.5?m.The strain WGR702 was pink-pigmented, motile, facultative anaerobe and non-spore forming. The range tem-perature and pH for strain WGR702 growth were 10℃～35℃ and pH 5.0～10.0 respectively. The strain WGR702 had a G+C content of 60.5 mol%. UV and gamma radiation survival curves showed the strain WGR702 had highly ionizing-radiation resistant. Phylogenetic analysis of the 16S rDNA gene sequences (EU315117) showed 94.79%～98.53% similarities with other recognized Serratia species. Primary charac-teristics that distinguish isolate WGR702 from the species of genus Serratia include the cells are spherical and Gram-positive. Based on the phenotypic, biochemical and physiological characteristics differences it is proposed that the new isolated strain WGR702 might be classified as a novel species of Serratia.

Objective To investigate the resistance mechanisms and epidemiology of Enterobacteriaceae isolated from clinical with reduced susceptibility to imipenem or meropenem.Methods 18 strains of Enterobacteriaceae with reduced carbapenem susceptibility were collected during January to August in 2010.The MICs of these strains were determined using automated microbial identification system.ESBLs,AmpC and KPC were tested using the agar dilution method.PCR amplification and DNA sequence were performed to analyze the KPC genes,PFGE was used to examine the molecular epidemiology.Results All 18 strains were detected ESBLs and AmpC,14 strains were detected KPC-2.3 strains with EDTA paper method positive may produce other metal carbapenem,in which 2 strains harbor KPC-2.PFGE types indicate that there were six genotypes among 15 strains of Klebsiella pneumoniae.Conclusion Plasmid-mediated KPC-2 was the main reason which makes Enterobacteriaceae reducing carbapenem susceptibility and causes short-term epidemic in hospital.Clinical strains harboring KPC-2 gene may carry multiple resistance genes meanwhile.

OBJECTIVETo identify the correlation of the volume of residual urine (VRU) with the severity of bladder outlet obstruction (BOO) and detrusor contractility in patients with benign prostatic hyperplasia (BPH).

METHODSA total of 152 patients with clinically diagnosed BPH underwent ultrasonography for measurement of the prostate volume and RVU, free uroflowmetry, and urodynamic examination for the severity of BOO and detrusor contractility. Using the software SPSS20. 0, we analyzed the correlation between the ultrasonographic results and urodynamic parameters and compared the two sample means by the t-test.

RESULTSThe prostate volume was correlated positively with BOO severity (r = 0.432, P < 0.01) and detrusor contractility (r = 0.343 , P < 0.01) while Qmax negatively with BOO severity (r = 0.327, P < 0.01) but not significantly with detrusor contractility (r = 0.123, P > 0.05). VRU showed a significantly negative correlation with detrusor contractility when > 150 ml (r = -0.490, P < 0.01), even more significantly when > 300 ml (r = -0.717, P < 0.01), but exhibited no significant correlation with it when ≤ 150 ml (r = 0.041, P > 0.05).

CONCLUSIONVRU can somehow predict the detrusor function. For patients with VRU > 150 ml, especially for those with VRU > 300 ml, the detrusor function should be evaluated and urodynamic examination is recommended for exact assessment of BOO severity and detrusor contractility.

ObjectiveTo study the effects of 9 different drying methods on total saponin content and antioxidant capacity ofParis polyphylla var.yunnanensis.Methods UV-VIS spectrophotometry was used for measuring the total saponin content ofP. polyphylla var.yunnanensis, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzthiozoline-6)-sulphonic acid (ABTS+) radical scavenging methods were used for evaluating the antioxidant capacity ofP. polyphylla var. yunnanensisextracts.ResultsThe total saponin contents ofP. polyphylla var.yunnanensis dried by different methods existed significant difference. The sample dried at 35℃ showed highest total saponin content (17.557 mg/g). The sample dried in the shade naturally showed middle total saponin content (13.740 mg/g). Based on the results of antioxidant capacity detected by two methods, the samples ofP. polyphylla var. yunnanensis dried by 9 different methods all showed good antioxidant capacity and showed a certain concentration dependence.Conclusion The samples dried at 35℃ have the highest antioxidant capacity. Therefore, drying at 35℃ is a better drying method to obtain high quality and high activity ofP. polyphylla var.yunnanensis.

Objective To investigate the effect of genistein (gen) on the secretion of vascular endo-thelial growth factor (VEGF) and matrix metalloproteinases (MMPs-1, 2, 3, 9) by fibroblast-like synoviocytes (FLS) from rats with collagen Ⅱ induced arthritis (CIA). Methods The CIA was induced by collagen Ⅱ and complete Freund's adjuvant (CFA) into rats. The rats were scored based on the arthritis index(AI) once a week. At the sixth week, the X-ray of joints was taken. The synovial tissues from knee joints were examined pathologically. The primary fibroblast-like synowocytes were separated from the synovial tissue by collagenase digestion and cultured. Then the expression of VCAM-1 was estimated by flow cytometry. After adding gen (100, 200, 400 μmol/L) at different concentrations into the FLS, VEGF and MMP-1, 2, 3, and 9 of the supernatants were tested by indirect ELISA. Results After 3 days of type Ⅱ collagen and CFA injec-tion, the rats started to catch arthrocele and their arthritis index increased gradually. The arthrocele was most remarkable at the 3rd week. The AI, X-ray and pathological examination indicated that the model group were significantly different from the control group. After the synoviocytes were cultured to the 4th generation, the expression of VCAM-1 was as high as about 85.5%. It showed that most synoviocytes were changed to fibro-blast-like synoviocytes. Different concentrations of gen (100, 200, 400 μmol/L) added to FLS were compared and revealed that the VEGF and MMP-1, 2, 3, and 9 in the supematants were suppressed evidently and in a dose-dependent manner. Conclusion The CIA model can be successfully constructed by collagen type Ⅱ and CFA. Tthe primary FLS of rats' joint can be separated and cultured well by collagenase digestion. Certain levels of gen can suppress the secretion of VEGF and MMP-1, 2, 3 and 9 hy FLS. The affect is dose-depen-dent.

To evaluate in vitro release and transdermal behaviors of Huoxue Zhitong gel, modified Franz diffusion cell methods was applied to investigate in vitro transdermal absorption of Huoxue Zhitong gel and the content of paeonolan in receptor fluid composed of PEG400%-95% ethanol-water (l:3:6)were determined by HPLC. The results were processed and different equations were fitted. The release law were in accordance with Weibull equation and the fitting equation was In[-1/(1 - Q)] = -0.790 51nt - 1.7012 (r = 0.9809). In 8 hours, cumulative release of paeonol was 85. 18% and the release rate was 2.827 µg . cm-2 h-1. Transdermal actions were consistent with zero-level model fit and the fitting equation was Q(t) = 1.7579t + 0. 7213 (r = 0.9991). In 8 hours, cumulative transdermal rate and transmission rate of paeonol was 54. 85%, 1. 820 µg . cm-2 h-1. So the Huoxue Zhitong gel had a good release and transdermal properties.
