Selective COX-2 inhibitors can promote the apoptosis of tumor cells and block the growth of new blood vessels through the inhibition of ring oxidase,vascular endothelial growth factor,microvessel and so on. Research shows that COX-2 is overexpressed in vascular and endothelial cells of lung cancer,select COX-2 inhibitors to adjuvant chemotherapy,not only can directly inhibit the tumor proliferation,but also can reduce the adverse reaction of chemotherapy drugs,and enhance the curative effect. To investigate the effects of selec-tive COX-2 inhibitors and cisplatin in lung cancer angiogenesis and its mechanism,will be a hope for the clini-cal treatment of tumor.

Objective To investigate the clinical value of vaginal myomectomy. Methods From March 2005 to May 2008,78 women with abnormal uterine bleeding were diagnosed with submucous myoma by hysteroscopy combined with ultrasonography. All the myomas were located in the lower uterine segment,and the diameter of the tumor ranged from 30 mm to 63 mm. The patients were divided into two groups to underwent vaginal myomectomy (vaginal group,36 cases) or abdominal electrotomy (open group,42 cases). The operation time,intraoperative blood loss,postoperative hospital stay and recovery of the two groups were compared. Results The vaginal operation was accomplished in all of the 36 cases. Compared with the open group,the vaginal group had significantly shorter operation time [(64.7?10.4) min vs (71.1?11.3) min,t=-2.599,P=0.011],less intraoperative blood loss [(200.0?38.4) ml vs (253.6?47.6) ml,t=-5.412,P=0.000],quicker recovery of bowel movement [(18.5?4.3) h vs (30.9?4.7) h,t=-12.078,P=0.000],and shorter postoperative hospital stay [(4.9?1.2) d vs (7.0?1.3) d,t=-7.368,P=0.000]. Follow-up was available in all of the 78 cases for 3 to 40 months (mean,28 months),during which no relapse occurred,and no statistical differences in pregnancy rate between the two groups was revealed [2.8% (1/36) vs 4.8% (2/42),?2=0.000,P=1.000]. The operation satisfaction rates in both of the two groups were up to 100%. Conclusions Vaginal myomectomy has advantages in less hemorrhage,fast recovery,short postoperative hospital stay,and low complication rate. For the tumors located in the lower uterine segment or those larger than 30 mm in diameter,vaginal myomectomy is an alternative to hysteroscopic electrotomy.

Objective To explore the risk factors contributing to wound complications following operative fixation for fractured calcanea.Methods Fitly-six patients with 61 fractured calcanea who had been treated with operative fixation from March 2000 to March 2003 were enrolled in investigation.General information of the pa- tients,ages,injury causes,classification of fracture,fall heights,smoking,delayed operation time,operation time and tourniquet time were documented preoperatively and postoperatively to be analyzed statistically.Results We report an overall wound complication rate of 14.8%(9/61).Wound infection,haematoma,dehiscence,heel necrosis and osteomyelitis were noted in our series.We identified the following as risk factors of postoperative wound compli- cations:1)fall from more than 3.4 m high(P＜0.05);2)delayed operation time less than seven days(P＜0.05); 3)operating time beyond two hours(P＜0.05);4)tourniquet time beyond 1.5 hours(P＜0.05).Conclusion In order to decrease wound complications following operative fixation tor fractured calcanea,surgeons should pertorm the operation 7 to 10 days after the injury,and reduce the operation time and tourniquet time.

Objective:To investigate the retinal toxicity of chitosan and gentamicin- chitosan gel. Methods:Sixteen albino New Zealand rabbits (weighted 1. 5-2.5 kg) were used in this study. The rabbits were divided into 4 groups randomly;each group was injected with 0.1 ml PBS, gentamicin 2 mg/ml,3% Chitosan gel, and gentamicin-chitosan gel (2 mg/ml) respectively. ①Ophtahlmoscopic examinations were done. Retina was observed prior to injection , and on 1st, 3 rd, 7 th, 14 th d and 28 th d after injection with direct ophthalmolscope observations. ②Electroretinographs (ERGs) were recorded prior to injection, and then on 3 rd,7 th,14 th d and 28 th d after injection were carried out. ③Light microscope and transmission electronicmicroscope examinations were performed four weeks after the injection. All eyes were enucleated, the retina examples were observed under light microscope and transmission electronic microscope. Results:Intravitreous injection with 3% chitosan was free of retina toxicity. The retina toxicity effects of gentamicin 200 ?g could be found with transmission electron microscope, but gentamicin-chitosan gel with the same dosage could decrease the damage. Conclusion:The result shows that chitosan can be used in the intravitreous injection.

ObjectiveTo observe the effection of different interventions of group B streptococcus (GBS) infection in gestation period.MethodsOne hundred and seventeen cases with GBS infection were obtained from 1885 pregnant women,who were got routine prenatal examination at 34 to 37 weeks of pregnancy,and drug seeitivity test of secretions which were taken from under paragraph 1/3 of vagina,and divided into treatment group (91 cases) and untreatment group (26 cases).The treatment group was divided into treatment group one (47 cases) and treatment group two (44 cases).Treatment group one was treated with oral antibiotics for 7 days after diagnosis,treatment group one and two were treated with postpartum antibiotics intravenous infusion once every 4 hours in labor.Comparison of maternal and fetal outcomes.ResultsThe GBS infection rate was 6.2％ (117/1885).The morbidity of premature delivery,premature rupture of membrane and neonatal infection of treatment group [ 5.5％ ( 5/91 ),13.2％ ( 12/91 ),5.5％ (5/91 ) ]were lower than those of untreatment group [ 19.2％(5/26),30.8％(8/26),23.1％(6/26) ](P ＜ 0.05).The morbidity of premature dehvery and premature rupture of membrane of treatment group one[ 0,6.4％ (3/47)]were lower than those of treatment group two[ 11.4％ (5/44),20.5％ (9/44)](P ＜ 0.05).Conclusion Anti-GBS treatment can improve the outcomes of mothers and infants,especially early anti-GBS treatment during the period of pregnancy.

Objective: To assess the effect and safety of Qilong Capsule (QLC) in treating apoplexy involving the meridians (Qi-deficiency and blood-stasis syndrome ). Methods: A randomized , do uble-blinded double-dummy controlled trial was adopted. One hundred and two pati ents were treated with QLC, 101 with Xiaoshuan oral liquid (XOL ) and 200 served as the open treatment group. Results: The total effective rate in QLC group was 89.22% and symptomatic relieved rate 44.12%,showing t hat QLC was more effective than XOL（P＜0.01）.Conc lusion: QLC is effective for apoplexy involving the meridians and has no side an d toxic effects.

Objective To observe the effects of Sancaoanqian decoction on expression of cytokine IL-1?, IL-6 and TNF RⅡ in experimental autoimmune prostatitis rats, and explore the target protein of cytokine of Chinese herbal compound in treating chronic nonbacterial prostatitis. Methods Seventy-two male Wistar rats were divided randomly into six groups and 12 rats in each group. All groups were made experimental autoimmune prostatitis rat model by injecting SC purified prostate protein with FCA except normal group. The normal and model group were given saline, western medicine group was given indomethacin, large, medium and small doses decoction groups were treated with large, medium and small doses of Sancaoanqian decoction. All rats were sacrificed after 30 days. The mRNA and protein expression of cytokines were tested by methods of immunohistochemistry and fluorescent quantitation RT-PCR. Results Sancaoanqian decoction could reduce the mRNA and protein expression of IL-1?, IL-6 in experimental autoimmune prostatitis rats. There were no significant difference between large and medium doses decoction group, but had a better activity than small dose. The expression of TNF RⅡ were reduced in all doses groups and no difference among three doses of Sancaoanqian decoction. Conclusion Sancaoanqian decoction can regulate the immune function in chronic prostatitis rat model. Down-regulation of cytokines maybe one of important mechanisms in treating chronic prostatitis.
