Background and purpose:Paclitaxel (Taxol,TXL) combined with cisplatin (DDP) has become the common chemotherapeutic regimen for cervical cancer. However, DDP has higher toxicities. Nedaplatin (NDP), a new platinum analogue,has been shown to have a higher antitumor efficiency against cervical cancer and lower toxicity. This study was done to investigate the antitumor effect of TXL+NDP on HeLa cells transplanted tumor compared with TXL+DDP. Methods:HeLa cells were transplanted subcutaneously in nude mice. These nude mice were randomly divided into 6 groups by sorting when tumor diameter reached 5-6 mm: Control, TXL, NDP,DDP, TXL+NDP,TXL+DDP. Tumor volume and body weight were measured during experiment. The volume ratio (T/ C) was the volume of single agent treatment group and control group and used to assess the antitumor effect, and the combination ratio (CR) was used for the combined therapy. More than 20% weight loss was defined as reaching toxicity level. Results:TXL+NDP regimen had a synergistic antitumor effect (CR=0.76) on HeLa cell transplanted tumor, with a maximum weight loss 8.3%. The tumor volume of TXL+NDP was 172?60 mm3, which was significantly smaller than that of TXL(304?55 mm3) group or NDP(356?67 mm3) group(P0.05), but had a higher toxicity with 4 mice death. Conclusion: TXL+NDP regimen has a synergistic inhibitory effect on HeLa cells and lower toxicity. The efficacy of TXL+NDP regimen needs to be confirmed in clinical trials.

Purpose:To study the effect of interferon-? on the growth of human cervical cancer transplanted subcutaneously in nude mice.Methods:Twenty-eight nude mice transplanted subcutaneously with human cervical cancer were divided into 4 groups: control group,positive control group(DDP group),IFN-? low dose group(1.5?10 7 u/kg) and IFN-? high dose group(3.0?10 7 u/kg). Different drugs were used from day 14 after transplantation and all mice were sacrificed after 49 days. The weight of the mice and the volume of tumor were measured. FCM was used for measuring the proportion of cell cycle S+G 2 -M(%) in tumor cells. Results:The growth inhibiting rates in DDP group,IFN-? low dose group,IFN-? high dose group were 92.8%,73.8% and 93.1% respectively. Except for mice in DDP group,there was obvious increase in the weight of mice in other three groups. As for the proportion of S+G 2 -M(%),there was no difference in control group,IFN-? low dose group and IFN-? high dose group. Conclusions:IFN-? can inhibit markedly the growth of transplanted cervical cancer,which is correlated with the IFN-? dose. The mechanism of IFN-? inhibiting cervical cancer was not due to the suppression of cancer cell proliferation.

Background and purpose:Cisplatin-based concurrent chemoradiotherapy(CCRT) has become the standard treatment for locally advanced cervical cancer(LACC) . But no marked survival benefi t was found for stage Ⅲ-ⅣA patients,and the high toxicity of cisplatin warrants evaluation of other chemotherapeutic agents to increase effi cacy and decrease toxicity. This study was done to evaluate the effi cacy and toxicity of paclitaxel(TXL) and nedaplatin(NDP) administered concurrently with radiotherapy followed by consolidation chemotherapy in the treatment of locally advanced squamous cell cervical carcinoma(LASCC) . Methods:29 Patients with LASCC(FIGO stage ⅡB-ⅢB) were enrolled into this study from February 5,2007 through December 10,2007. The median age was 48 years old(35-64) . Radiotherapy included external beam radiotherapy to pelvic(stageⅡB 45Gy,stage Ⅲ 50 Gy) and 192Ir brachytherapy(stageⅡB 50 Gy,stage Ⅲ 35Gy) . TXL 35 mg/m2 and NDP 20 mg/m2 were given every week for 6 weeks concurrently with radiotherapy. After one month of CCRT,TXL 135 mg/m2 and NDP 60mg/m2 were administered every 3 weeks for 4 cycles. Results:All patients completed CCRT. For the consolidation chemotherapy,25 patients received 4 cycles,2 patients 3 cycles and 2 patients 2 cycles. The clinical complete response rate was 89.7%(95%CI,78.6%-100%) ,partial response rate 10.3%(95%CI,0-21.4%) After a median follow-up of 14 months(range,8.7-18.8 months) ,the disease-free and overall survival rates were 86.2%(95% CI,73.7%-98.7%) and 96.7%(95% CI 90.2%-100%) ,respectively. One patient died due to disease progression.During CCRT,Grade 3 leukopenia occurred in 3.6%(6/169) of the cycles,Grade 3 diarrhea 0.6%(1/169) ;During consolidation chemotherapy,Grade 3 leukopenia and neutropenia occurred in 8.7%(9/104) of the cycles. There were 2 patients who developed Grade 3 late rectum toxicity. Conclusion:CCRT with paclitaxel and nedaplatin followed by consolidation chemotherapy is well tolerated and effective in patients with LASCC. A prospective randomized trial to compare this treatment strategy with standard CCRT seems to be worthwhile.

Objective To investigate the involvement of mitogen-activated protein kinase(MAPK)system and hypertrophy related genes in myocardial remodeling mechanism of patients with congestive heart failure(CHF).Methods Thirty-nine patients of mitral valve disease with CHF were randomly selected and 30 cases of healthy persons were included as controls.Cardiac function parameters were measured by echocardiography.Concentration of AngⅡ in plasma and myocardial tissues were determined by radio immunoassay.Immunoprecipitation was used to assay the protein expression and phosphorylation of c-jun NH2-terminal kinase(JNK),extracellular signal regulated kinase(ERK),P 38- mitogen-activated protein kinase(P 38-MAPK)in myocardial tissues;protein expression of c-myc,c-myb,c-jun was also determined by immunoprecipitation.Results Compared to the control group,the phosphorylation of ERK1/2 was obvious in heart function class Ⅱ group(P0.05);phosphorylation of JNK was obvious in CHF groups(P0.05);there was no expression in control group.Conclusion MAPK activated by renin angiotensin system may play an important role by causing the protein expression of c-myc,c-myb,c-jun in myocardial remodeling in patients with CHF.

Objective To investigate the involvement of mitogen-activated protein kinase(MAPK)and PI3K(phosphatidylinositol 3 kinase)/ Protein kinase B(Akt) signal transduction pathways in the mechanism of myocardium remodeling in patients with congestive heart failure(CHF).Methods Thirty nine patients of mitral valve disease with CHF were randomly selected and 30 cases of healthy persons were included as controls.Cardiac function parameters were measured by echocardiography.Concentration of AngⅡ in plasma and myocardial tissues was determined by radio immunoassay.Activity of PKC was determined by using competive prote in binding method,activity of MAPK was detected by the methods of immunoprecitipation.Immunoprecitipation was used to assay the protein expression and phosphorylation of PI3K and Akt(Protein kinase B),protein expression of C-FOS and ?-skeletal-actin in myocardial tissues.Results Pathological changes of myocardial tissues in CHF with valvular heart diseaseshowed typical myocardial remodeling.The hypertrophy was dominant at early stagy of CHF,while at end stage the characteristics include disordered alignament of the myocytes,the discontinuity and dissolving of cardiomyofibrills,destroyed subcellular organs,and the hyperplasia of interstitial tissue.AngⅡ concentration in plasm and myocardial tissues in patients with CHF was higher than those in the control group(P

Objective To investigate the timing and role of systemic retroperitoneal lymphadenectomy in patients with ovarian cancer. Methods From Jan. 1987 to Feb. 1994, 50 patients with ovarian cancer, who underwent retroperitoneal lymphadenectomy on second-look laparotomy (SLL), were retrospectively studied. Results The median age was 49 years. Overall survival at 3 and 5 years were 72% and 62%, respectively. Twenty of 50 (40%) women were found SLL(+),and the rates of positive SLL were related to International Federation of Gynecology Obstetrics (FIGO) stage, with 16% in stage ⅠandⅡ, 64% in stage Ⅲ and Ⅳ (P
