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 .

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 investigate the expression of human macrophage metalloelastase(HME) both in gastric cancer cell lines and gastric cancer tissues,and to find the role of HME in gastric carcino genesis.Methods Fifty eight patients who were operated in our hospital during April to Aug.2003 were enrolled.The samples taken from cancer,paracancer or normal tissues of these patients and cancer cell lines(MGC-803,SGC-7901,AGS)were detected for HME protein and HME mRNA expressions by Western blot and immunohistochemistry,RT-PCR and fluorescence quantitative PCR,respectively. Results Both HME mRNA and HME protein expressions were found in all three gastric cancer cell lines.The expressions of HME mRNA and HME protein in gastric cancer tissues was increased signifi- cantly compared with that in normal tissues(P0.05).Conclusions The increased HME expression in gastric cancer tissures compared with normal tissue indicate that HME may be a potential tumor marker for gastric cancer.

Objective To evaluate the curative effect of chemotherapy combined with radiotherapy for limited-stage small cell lung cancer(LD-SCLC).Methods 34 cases of patients with LD-SCLC were rand- mized into interdigitating chemoradiotherapy group and sequential chemoradiotherapy group.All patients re- ceived four to six cycles of alternating CE(C:carboplatin 300 mg/m~2 d_1;E:etoposide100 mg d_(1～5)and CAP(C: cyclophosphamide 600 mg/m~2 d_(1,8);A:adriamycin 40 mg/m~2 d_1;P:cisplatin 50 mg d_(3～5)chemotherapy,three weeks for a cycle.All patients also received thoracic radiotherapy with conventional fraction,2.0 Gy per frac- tion,five fractions per week.The total dose was 60 Gy.Results In interdigitating chemoradiotherapy group, CR was 64.7%,PR was 29.4%,NR was 5.9% and PD was 0 after chemo-radiation therapy.In sequential chemoradiotherapy group,CR was 23.5%,PR was 52.9%,NR was 23.5% and PD was 0 after chemothera- py,and CR was 58.8%,PR was 35.3%,NR was 5.9% and PD was 0 after radiotherapy.Conclusion The therapeutic effect of chemotherapy combined with radiotherapy for LD-SCLC was satisying.There was no sig- nificant difference in the effect between the two groups.

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.
