Objective:To investigate the role of anaphylatoxin C 5 a in patients with asthma .Methods:A prospective study was performed between September 2006 and February 2007.A total of 33 patients with acute exacerbation of asthma and 13 healthy subjects were recruited into the study .The patients with acute exacerbation of asthma were also studied when they returned to the remission state .Levels of lung function, levels of C5a in induced sputum and cell differential count in induced sputum were determined . Results:The level of C5 a in induced sputum was significantly higher in patients with acute exacerbation of asthma [0.85(0.68-2.13) μg/L] than that in patients with stable asthma [0.45(0.26-0.88)μg/L, Z=-2.193, P=0.013];Sputum C5a levels in stable asthma patients were significantly higher than those in healthy controls [0.14(0.06-0.45) μg/L, Z=-2.141, P=0.015].The level of C5a in patients with severe exacerbation [2.21(1.27 -9.0) μg/L] was significantly higher than those in patients with mild exacerbation [0.34(0.17-0.63) μg/L] and moderate exacerbation [0.85(0.55-1.67) μg/L,χ2 =12.330, P=0.001].The level of C5a in induced sputum was positively correlated with the number of total cells count (r=0.797, P=0.004), neutrophils (r=0.504, P=0.032) and macrophages ( r =0.424, P=0.036 ) in acute exacerbation of asthma .Conclusion: C5a levels in induced sputum could be identified as an important prognostic biomarker , which involved in asthma ’ s pathogenesis .

Objective To explore the effects of applying microsurgical technique in the one-stage urethroplasty for hypospadias with longitudinal preputial island flaps of dorsum penis. Methods Forty-two hypospadias cases with obvious phallocampsis were reviewed. The patients aged from 1 to 19 years (median, 6.4 years). Among them, 6 cases were of coronary suleus type, 28 cases of pe-nis body type, and 8 cases of penis and scrotum type. All patients went through the operative proce-dures by microscope with four-times magnification and microsurgical instruments. Longitudinal prepu-tial island flaps of dorsum penis was employed for the treatment of 33 cases of these patients, and 9 cases underwent longitudinal preputial island flaps of dorsum penis combined scrotal septal pedicle flaps. Results Thirty-eight cases were cured by one-time surgery (90.5%). One case with urethral fistula after operation was cured by surgical repair of urethral fistula. Two cases with urethral meatus stricture after operation and one with urethral stoma stricture were cured by dilatation. Patients were followed for 9 to 52 months (mean, 27 months). Conclusion Use of microsurgical technique with longitudinal preputial island flaps of dorsum penis in one-stage urethroplasty for hypospadias improved the success rate of surgery with few complications.

To optimize the growth condition for the established gene engineer bacteria express cardiac troponin-I(cTnI) and to obtain purified cTnI as an antigen to produce clinical assay kits used in acute myocardial injury(AMI) diagnosis.Plackett Burman Design(PBD) was applied to select the factors which effect the expression of cTnI in Escherichial coli(E.coli) mostly.Induction time,pH and KCl were proved influenced expression of cTnI notably.Afterward,Response Surface Methodology(RSM) as second step to optimize the selected three factors,an equation was deduced to predict the percent of cTnI.In the most optimized condition,the percent of cTnI can reach to 26% of total cell protein.The procedures of purification included ammonium sulfate deposition and DEAE Cellulose ion exchange chromatography.SDS-PAGE shows that purified cTnI contain one band.cTnI could be used to immune animals as an antigen to produce monoclonal antibodies with high affinity and specificity.It maybe as calibrators to harmony the difference assays of cTnI measurement in clinical.

Objective To study the antitumor effect of toremifene on MCF7 cell lines,and investigate the role of mitogen-activated protein kinase pathway. Methods Inhibitory effect of toremifene alone or combined with MEK inhibitor PD98059 on MCF7 cells was measured by SRB test,and that on phosphorylated ERK was detected by Western blotting.Results Toremifene exhibited a concentration-dependent inhibitory effect on the activity of MCF7 cells.Phosphorylated ERK was significantly inhibited by 5,10 and 20 mmol/L toremifene.Combined with PD98059,toremifene had a significantly enhanced cytotoxity effect,which exceeded that of application alone. Conclusion Mitogen-activated protein kinase pathway may play an important role in the antitumor effect of toremifene which is independent of estrogens.Combined with PD98059,the antitumor effect of toremifene can be reinforced,indicating a synergistic effect of these two drugs.
