Objective:To investigate the inhibitory effect of RNA interference (RNAi) on the expression of Aurora-A in SKOV3 cells and on proliferation of SKOV3 cells.Methods:Two pairs of oligo small interference RNA (Oligo siRNA) specific for Aurora-A were designed for RNAi and were transferred into SKOV3 cells.The expression of Aurora-A were de- tected by RT-PCR and Western blot.Furthermore,the cell proliferation and apoptosis were observed by MTT and FCM af- ter transfection.Results:After transfection with Oligo siRNA,mRNA and protein level of Aurora-A gene in SKOV3 cells were obviously reduced,while the inhibitory rate of proliferation and apoptosis rate in SKOV3 cells were increased signifi- cantly.Conclusion:The Oligo siRNA specific for Aurora-A can reduce the expression of Aurora-A gene and induce apop- tosis of SKOV3 cells.

Objective To observe the preventive efficacy and safety of dexmedetomidine with parecoxib sodium on the patients with postoperative hyperalgesia induced by remifentanil. Methods A total of 100 female patients undergoing elective surgery under general anesthesia were as-signed into four groups according to the table of random number:the control group (group C),the parecoxib sodium group (group P),the dexmedetomidine group (group D)and the parecoxib sodium combined with the dexmedetomidine group (group DP).The vital signs were monitored and the total intravenous anesthesia was performed.All the patients were give intravenous injection of 0.2μg·kg-1 ·min-1 remifentanil and 4-12 mg·kg-1 ·h-1 propofol to maintain the anesthesia.Patients in group P were given 40 mg parecoxib sodium 30 minutes before the end of the operation.Patients in group D were give intravenous injection of 0.6μg·kg-1 ·min-1 dexmedetomidine consistently till 30 min before the end of the operation.Patients in group DP were given 0.6 μg·kg-1 ·min-1 till 30 min before the end of the operation and were given 40 mg parecoxib sodium.The VAS scores were re-corded at 1,2,6,12,24 hours.The cases of agitation,rigors,nausea and vomiting and increasing of analgesics were recorded.Results The postoperative VAS scores in group P,group D and group DP were significantly lower than group C(P <0.05).The postoperative VAS scores in group DP were significantly lower in group P and group D (P<0.05).Cases of agitation and rigors in group D and group DP were less than group C(P <0.05).The increasing of analgesics in group DP was much higher than other groups(P<0.05).Conclusion After induced,patients were given intravenous in-jection of 0.6 μg·kg-1 ·min-1 dexmedetoniding consistently till 30 min before the end of the opera-tion were given 40 mg parecoxib sodium can effectively prevent hyperalgesia after remifentanil anes-thesia without significant increase in revival time and obtain a better sedation.

Objective To examine the levels of fractional exhaled nitric oxide in bronchial asthma and the cor-relation between fractional exhaled nitric oxide and pulmonary function tests as well as the value of pulmonary function tests in curing the children with bronchial asthma. Methods Seventy - two asthmatic children came from Guiyang Ma-ternal and Child Health Hospital were studied. They were divided into 2 groups:mild - to - moderate asthma group(36 cases)and serious asthma group(36 cases). Fractional exhaled nitric oxide level and the lung function were measured and the correlation analysis was analyzed by SPSS 13. 0 software. Results The fractional exhaled nitric oxide concen-tration of the serious asthma group was significantly higher than that of the mild - to - moderate asthma group[(47 ± 26)ppb vs(29 ± 15)ppb,t = 3. 543,P ﹤ 0. 01],1 - second rate,maximum mid - expiratory flow(MMEF),and peak expiratory flow(PEF)in mild - to - moderate asthma group were significantly higher than those in serious asthma group[(99. 74 ± 9. 81)% vs(87. 17 ± 13. 30)% ,(87. 12 ± 35. 61)% vs(68. 90 ± 30. 88)% ,(99. 97 ± 10. 83)% vs (94. 31 ± 17. 69)% ](P ﹤ 0. 01,0. 05,0. 05). No correlations were found between fractional exhaled nitric oxide level and the lung function parameters,including forced expiratory volume in 1s(FEV1),1 - second rate,MMEF and PEF in the mild - to - moderate asthma group(r = 0. 073,0. 087,0. 242,0. 326,all P ﹥ 0. 05). However the level of fractional exhaled nitric oxide was negatively correlated with the lung function parameters,including FEV1,FEV1 / FVC,MMEF and PEF in serious asthma group(r = - 0. 354,- 0. 573,- 0. 478,- 0. 471,P ﹤ 0. 05,0. 001,0. 005,0. 005),respec-tively. Conclusions Monitoring of fractional exhaled nitric oxide and the lung function parameters can effectively indi-cate the state of illness of asthmatic child,which plays a key role in the treatment.

Objective:To investigate the significance of 25 ( OH )-vitamin D in its diagnostic value of primary biliary cirrhosis. Methods:44 cases with PBC,41 cases with Hepatitis B cirrhosis and 110 normal people as control group were all analyzed bi-ochemical results and significance of serum 25 ( OH )-vitamin D. We Used receiver operator characteristic curve ( ROC ) to analyze serum 25(OH)-vitamin D in its diagnostic value of primary biliary cirrhosis. Results:Biochemical results of TBIL,DBIL,IBIL,GLB, AST,ALT,ALP,γ-GT were higher in PBC than that in normal people and Hepatitis B cirrhosis. While the serum 25(OH)-vitamin D of PBC was much more lower than that in normal and people and Hepatitis B cirrhosis. The difference between them were statistical difference(P<0. 05). The area under the ROC curve of PBC was 0. 926,it showed serum 25(OH)-vitamin D diagnosis for PBC had quite value. When the cut-off level of serum 25(OH)-vitamin D was 17. 275 ng/ml,the sensitivity for the diagnosis was 92. 8%,the re-spectively was 84. 1%. Conclusion:Serum 25(OH)-vitamin D diagnosis for PBC has quite value,the cut-off level of serum 25(OH)-vitamin D is 17. 275 ng/ml.

Objective To investigate the effects of different doses of dexamethasone used at different time on the serumal concentrations of TNF ?, IL 1? and IL 6 of rats after severe scald in order to provide experimental basis for reasonable usage of ectogenous glucocorticoids for severe traumas. Methods The serumal concentrations of TNF ?, IL 1? and IL 6 were detected by ELISA after intraperitoneal injection of different doses of dexamethasone into rats at different time after severe scald. Results High dose(5 mg/kg) and low dose (0.5 mg/kg) of dexathemasone used during the period from 4 h to 12 h after severe scald could both significantly reduce the serumal concentrations of TNF ?, IL 1? and IL 6, and the effect of high dose was much better than that of low dose. Both doses of dexathemasone used at 24 h after scald had a significant effect on IL 1? and IL 6, but there was no difference between the two doses. No obvious effects were found of high/low dose of dexamethasone used 48 h later after scald. Conclusion According to the anti inflammatory effect, the best therapeutic efficacy may result from high dose of ectogenous glucocorticoids during the period from 4 h to 12 h and low dose from 12 h to 24 h after severe scald.

Objective To investigate the changes of the expression of HSP90? in the liver of severely scalded rats at the early stage of stress Methods The expression levels of HSP90? in the liver of rats at different time points after severe scald were detected by Western blotting and then the expression of HSP90? in the nucleuses was observed by immunohistochemistry Results The expression of HSP90? significantly increased in the liver of rats after severe scald, especially during 12~48 h Abnormal high expression of HSP90? in the nucleuses around was found at 48 h after scald Conclusion The abnormal high expression of HSP90? due to severe scald may be one of the important causes resulting in the disorder of glucocorticoid receptor at the early stage of stress after severe trauma.
