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: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.

Methods The clinical information of 174 patients were retrospectively analysed.Results The percentage of new cervical cancer cases from 1991 to 2001 was 1.2%, 1.2%, 4.3%, 4.2%, 4.6%, 4.5%, 7.3%, 9.0%, 10.7%, 9.4%, 10.8%, respectively( P 0.05).For patients with two or more risk factors, it was 68%, 1/7, respectively ( P

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.

[Abstract ] Objective To investigate the molecular mechanism how genistein increased the sensitivity of colon cancer cell to 5-fluorouracil(FU)and promoted colon cancer cell apoptosis.Methods SW480 colon cancer cell line was chosen as experimental object.Genistein 80 μmol/L and 5-FU 30 μg/mL used separated or combined for 48 hours were set as drug experiment group.There were four experiment groups in this study:control group (without any drug),5-FU group,genistein group,5-FU and genistein combined group.The expression of survivin,Bcl-2,p21 ,caspase3 and caspase 9 in the tumor cells of each group at mRNA and protein level was deteced by real-time quantitative polymerase chain reaction (PCR) and Western blotting.The relative expression quantity of genes was determined by comparative threshold method (2 -ΔΔCT )andβ-actin was taken as an internal reference.Semi quantitative analysis was performed for protein relative expression quantity.The DNA combination activity of nuclear factor(NF)-κB of each group was measured by electrophoretic mobility shift assay (EMSA).Single factor analysis of variance was used for mean comparison among multiple groups and LSD test was for mean comparison between two groups.Results The expression of caspase3,caspase 9 and p21 of 5-FU and genistein combination group at mRNA (1 .903±0.122,2.726±0.050 and 2.541 ±0.393)and protein level (0.534±0.077,1 .161 ± 0.172 and 0.463±0.016)were all higher than those of control group (1 .001 ±0.052,1 .000±0.014 and 1 .001 ±0.037;0.080 ±0.043,0.248±0.059 and 0.139 ±0.021 ),genistein group (1 .559 ±0.038, 2.394±0.095 and 1 .686 ±0.061 ;0.335 ±0.052,0.478 ±0.059 and 0.304 ±0.018)and 5-FU group (1 .198±0.063,1 .051 ±0.043 and 1 .399±0.055 ;0.194±0.015 ,0.337 ±0.036 and 0.231 ±0.011 );the expression of survivin of 5-FU and genistein combined group at mRNA and protein level (0.165 ± 0.018 and 0.216±0.014)were all lower than those of control group,genistein group and 5-FU group (1 .001 ±0.033,0.775 ±0.044 and 0.395 ±0.030;0.594±0.079,0.375 ±0.014 and 0.295 ±0.014), and all the differences were statistically significant (gene,F = 802.865 ,52.760,39.992,187.288, 37.435 ;protein,F =10.466,44.483,19.490,200.011 ,45 .238;all P <0.01);the difference was also statistically significant in the expression of caspase3 and p21 of 5-FU group and genistein group compared with those of control group (LSD test,P <0.05 ).The results of EMSA assay showed that the DNA binding activity of NF-κB protein of genistein group (461.64 ±15.41 )and combined group (585.28 ±7.82) significantly decreased compared with that of control group (1 067.97 ±36.01)and 5-FU group (718.83± 23.18,LSD-test,P < 0.05).Conclusions Genistein combined with 5-FU seemed to have synergistic effects on apoptosis of colon cancer cell.The mechanism was that genistein inhibited the DNA binding activity of NF-κB mediated by genistein,further up-regulated caspase 3,caspase 9,p21 and down regulated survivin.Therefore,genistein may provide assistance in colon cancer chemotherapy.

Objective To investigate the clinical significance of invasive hemodynamic monitoring in early interventional treatment of acute massive pulmonary embolism.Methods From 2010 June to 2014 January,40 cases of acute massive pulmonary embolism admitted to the ICU in our hospital were analyzed divided into experimental group (20 cases) and control group (20 cases):while receiving conventional dose of peripheral venous thrombolytic therapy,the therapeutic effect of thrombolysis was evaluated by different ways.In experimental group,adopted Vigileo technology for continuous monitoring SVV,CI and ScvO2,guiding thrombolytic and interventional therapy after 12 hrs.If after 24 hrs the right ventricular ejection fraction (RVEF) and pulmonary artery systolic pressure (PSAP) did not improve,patients were converted to interventional therapy.We compared the CVP,MAP,PO2/FIO2,RVEF,PSAP,28-day mortality and the change in pulmonary vascular after 6 month.Result In two groups,CVP,MAP,PO2/FIO2 improved similarly after thrombolytic therapy.The experimental group were under the continuous monitoring of hemodynamic,12 patients were shifted to interventional therapy when ScvO2,SVV,CI did not increase after 12 hours.While 4 patients in control group were converted to interventional therapy after 24 hours.In the experimental group after 24 hours thrombolytic,the PO2/FIO2,RVEF and PSAP were higher than those in the control group.Compared with the control group,28-day mortality were same,but after follow up six moths RVEF,PSAP significantly improved.Conclusions FloTrac/Vigileo monitoring technology can be applied in assessment of massive pulmonary embolism thrombolytic to guide early interventional therapy,improve the oxygenation and right heart failure in the early stage,reduce the occurrence of pulmonary hypertension,improve the long-term pulmonary function.
