Objective To assess the anticonvulsant effect of midazolam, thiopental and propofol on the convulsion induced by ropivacaine in rats and the underlying mechanism.Methods Fifty male SD rats, 4-6 months of age, weighing 250-300 g were randomly divided into five groups of 10 animals each : (1) control group (C); (2) ropivacaine group; (R) (3) midazolam-ropivacaine group (MR); (4) thiopental-ropivacaine group (SR) and (5) propofol-ropivacaine group (PR) . In control group normal saline 2 ml was infused i.v. . In ropivacaine group (R) 0.75% ropivacaine was infused i.v. at 0.5 ml?min-1 until convulsion occurred. In midazolam - ropivacaine group (MR) midazolam 0.23 mg?kg-1 was injected i.v. 3 min before 0.75% ropivacaine infusion. In SR and PR groups thiopental 2 mg?kg-1 or propofol 1 mg?kg-1 was injected i.v. 1 min before 0.75% ropivacaine infusion. As soon as convulsion occurred ropivacaine infusion was stopped. The animals were decapitated and their brains were removed and kept in liquid nitrogen for determination of the contents of excitatory ammo-acids (aspartic acid and glutamic acid) and the inhibitory amino-acids [glycine and ?-amino butyric acid (GABA)] by high-performance liquid chromatography . The amount of ropivacaine infused in each group was recorded and calculated.Results The dose of ropivacaine needed to produce convulsion was 4.6?0.5 mg?kg-1 in group R and was significantly increased in the 3 groups pretreated with general anesthetics and was 2.96 times the dose in group R in MR group, 2.84 times in SR group and 1.54 times in PR group. The 4 amino-acid concentrations in the brain were significantly higher in group R than in control group. Compared to group R the Asp, Gly and GABA concentrations were significantly lower in group MR and PR but in group SR only Asp concentration was significantly lower. There was no significant difference in glutamic acid concentration among the4 roopivacaine groups (group 2-5).Conclusion Midazolam, thiopental and propofol can all increase the dose of ropivacaine needed to induce convulsion and midazolam and thiopental are more effective than propofol.

The fermentation broth of one actinomycete strain ACMA006 strongly inhibited growth of many tumor cells and some microorganisms, but its cytotoxicity to human normal cells were weak. Strain ACMA006 grow well on most tested media, producing exuberant vegetative hyphae and aerial hyphae. Its optimization temperature is 28?C. Phyloge-netic analysis based on 16S rDNA sequence showed that strain ACMA006 was closely related to one of the genus Streptomycetes (S.cavourensis subsp. washingtonensis) with 16S rDNA sequence similarity values of 100%, but had many differences in other features including its morphology, physiological and biochemical characteristics. The pre-liminary study supported the view that the strain ACMA006 represented a new strain of the S.cavourensis subsp. wash-ingtonensis.

Objective To observe the expression of mitochondrial encoding cytochrome oxidase subunitⅠ(COXⅠ) and subunitⅡ(COXⅡ) in type Ⅱalveolar epithelial cell(AEC Ⅱ) of rats exposed to hyperoxia and explore the role of COXⅠand COXⅡ in hyperoxia-induced lung injury.Methods AECⅡ were gained by primary culture from 19-days fetal rats lung.After purified,AECⅡ were randomly assigned to hyperoxia group and air group.Hyperoxia group was flushed the flake with 950 mL/L O2 and 50 mL/L CO2 at 3 L/min for 10 min,then sealed.Both groups were in CO2 culture chamber(37 ℃,50 mL/L CO2).After 6,12 and 24 hours of exposure,AECⅡ were harvested and extracted for total RNA.COXⅠand COXⅡ mRNA were detected by reverse transcription polymerase chain reaction(RT-PCR).The results were analyzed by SPSS 12.0 softwore.Results Compared with air group,COXⅠmRNA expression in hyperoxia group increased significantly at 6 hours(t=3.832 P=0.019) and 12 hours(t=10.431 P=0),respectively,then decreased to the equivalent level in 24 hours(t=0.360 P=0.731).Compared with air group,COXⅡmRNA expression in hyperoxia group increased significantly at 6 hours(t=2.795 P=0.035),then decreased to the equivalent level at 12 hours(t=0.892 P=0.40) and 24 hours(t=2.018 P=0.071).Conclusions Exposure of hyperoxia up-regulate the expressions of COXⅠmRNA and COXⅡmRNA in AECⅡ,which may be a protective mechanism of hyperoxia-induced lung injury.

Objective To measure the length between the bifurcation of abdominal aorta to the femoral artery puncture point in adult women.Methods 127 patients were enrolled in the study.Femoral artery puncture using of the roberts uterine catheter (RUC) for the diagnosis and treatment of obstetrics and gynecologic disease was conducted.When the RUC bending vertex code located at the bifurcation above, fingers fixed femoral artery puncture point at the mouth of the catheter's sheath and evacuate the catheter and measure the code to the fixed position.Results In this group, the length of the bifurcation of abdominal aorta to the femoral artery puncture point was 24.38-25.33 cm.There was no significant difference in the length with patient age (P>0.05), but there were statistical significances with the patients height and weight(P<0.05).Conclusion The length of adult women abdominal aortic bifurcation to the femoral artery puncture point has no significant difference with patient age.The individual height and weight are very much significant.The length estimation can be done according to the patient's height and weight for low abdominal aortic catheter,on clinic for avording X-ray irradiation or no X-ray equipment condition.

A 880 bp cDNA localized to the putative NS5 region of HGV genome was expressed in E.coli BL21(DE3). The cDNA fragment was inserted into a plasmid pGEX-5X-1,at the downstream of the DNA sequence encoding Schistosoma japonicum glutathione S- transferase(GST),in the same reading frame with the gene of GST. A 60KD GST-NS53 fusion protein was expressed at 37℃ in a form of inclusion bodies amounting to 30 percent of total host protein whereas at 20℃ mainly in a form of soluble protein . The fusion protein was extracted and purified to homologue. The purified GST-NS53 fusion protein could be specifically recognized with either the sera from the patient infected by HGV or the antisera directed against GST.

Background Many methods are widely studied to improve the therapeutic effect of trabeculectomy for glaucoma,and the clinical effectiveness of the amniotic membrane application during trabeculectomy is one of the research hotspots.Objective This study was to evaluate the efficacy and safety between trabeculectomy with (TE-AMT) and without amniotic membrane transplantation (TE-noAMT) for treating glaucoma.Methods Articles published from 1965 to December 2010 were searched from The Cochrane Library,PubMed,EMBASE,CNKI,Chinese Biomedicine Database,internet by computer,and manual search then was performed according to the predetermined strategy.Randomized controlled trials (RCT) on TE-AMT and TE-noAMT were included.The quality of included articles were scored based on Jadad table,and the relative parameters and information were extracted,including author,design of the trials,country,number of eyes and patients,gender,follow-up duration,age,classification of glaucoma,baseline IOP and loss rate.The main analysis indicators were the percentage of IOP reduction,completely operative successful rate,qualified success rate and adverse events.The pooled estimates were carried out with RevMan version 5.0 software.Results Nineteen RCTs documents were reviewed by meta-analysis with the Jaded scores ≥3 in 2 papers and ＜3 in 17 papers.Total 977 eyes of 818 patients were included.The weighted mean differences (WMD) of the percentage of IOP from baseline were (WMD =8.47％,95％ CI:5.20-11.75) at 6 months and (WMD=9.37％,95％ CI:4.97-13.77) at 12 months postoperatively.Relative risk (RR) of complete success rate and qualified success rate at postoperative 6 months were (1.40,95％ CI:1.19-1.65) and (0.47,95％ CI:0.22-1.00),respectively.RR values of adverse event such as shallow anterior chamber,hyphema,hypotony and choroidal detachment,failed filtering blebs at 6,12 months were 0.51 (95 ％ CI:0.30-0.85),0.43 (95％ CI:0.20-0.92),0.51(95％CI:0.26-1.00) and 0.57(95％CI:0.14-2.31),0.31(95％CI:0.20-0.47),0.31 (95％ CI:0.17-0.55),respectively.Conclusions TE-AMT appears to have better efficacy in lowering IOP,increasing complete success rate and reducing adverse event I in comparison with TE-noAMT.
