Purpose:Our experiments are dealing with the affect of docosahexaenic acid(DHA) in doxorubicin to cytoxicity effect of MDA-MB-435s, which is of the anti-human breast cancer and whether it is one of the effect mechanisms that it via the lipid peroxidation of DHA.Methods:Add different match such as anti-cancer drugs?PUFAs?oxidan system of sodium ascorbate and ?-methy-1.4-naphoqui-none?antioxidant of Dl-?-tocopherol and so on to the culture cell line of MDA-MB-435s each 24 hours for 6 days, estimate MDA by TBA with cell extracts and estimate the contents of NO via nitrite salt spectrophotography, then draw out a dosage-effect correlation straight line among contents of MDA,NO and cytoxicity. Mitox is used as contraposition to the peroxidation of ADM which is enhanced by DHA for peroxidation of mitox is low.Results:There have been obvious changes on the contents of MDA of the lipid peroxidation has paralled increased while NO has decreased. There is recitilinear correlation relationship among the contents of MDA and NO from cell extracts and the cytoxicity.Conclusions:It is obvious that DHA can add the cytoxicity of cell line of MDA-MB-435s with ADM, particularly after add non-cytoxicity oxidant. It is lipid peroxidation of oncocyte that one of the mechanisms of DHA can enhance anti-breast cancer effect of ADM.

Objective To investigate the pathogenesis,high risk factors,clinical characteristics,methods of diagnosis and treatment,and prognosis of vaginal intraepithelial neoplasia (VAIN).Methods The clinical data of thirteen cases of VAIN treated in Zhejiang Provincial Cancer Hospital dated Mar.2002 through Dec.2008 were reviewed and analyzed retrospectively.Results Twelve of 13 VAIN cases were performed the human papillomavirus(HPV) detection with 92% (11/12) HPV positive rate.None of the cases shown specific clinical manifestation.Among the 13 cases,6 of them accompanied with cervical cancer,4 cases with cervical intraepithelial neoplasia (CIN ),and 3 cases with vulvar intraepithelial neoplasma (VIN).Five cases synchronously diagnosed with cervical lesion and 3 with vulva lesion were underwent surgery,while the other 5 cases were diagnosed metachronously.Among 8 cases underwent surgery,1 case with CIN underwent argon plasma coagulation (APC) after surgery,1 case with the positive edge of VIN underwent APC.During follow up,1 case with locally advanced cervical cancer underwent radiotherapy again,3 cases with VAIN received APC,while 1 cervical cancer cases with VAIN received no treatment.The average follow-up time was 25.6 months (range 6-87 months).Two cases died of cervical cancer metastasis.The other 11 cases were normal and still alive.None of them progressed to invasive carcinoma.Conclusions The main reason of VAIN is HPV infection.There are not specific clinical manifestations,usually diagnosed when reviewing cervical or vulva lesions and rarely progressed to invasive carcinoma.The main treatment of VAIN is surgery with the adjuvant treatment of APC.

Objective To explore the safety and efficacy of hepatic resection with selective hepatic vascular exclusion(SHVE). Methods SHVE was used in 246 consecutive patients undergoing major or complex liver resection in our center. Preoperative demographic and clinical data,details of the surgical procedure, pathologic diagnosis, postoperative course and complications were collected and analy zed. Results From January 2000 to July 2007, liver resections were performed IJnder SHVE in 246 patients; total SHVE, right partial SHVE and left partial SHVE in 145, 54 and 47 patients, respectively. SHVE was converted to total hepatic vascular exclusion(THVE)in 3 patients to repair the wall of inferior vena cava(IVC). Hemodynamic tolerance to SHVE was excellent, only with a slight increase in systemic and pulmonary vascular resistance during clamping.There were no deaths. and the morbidity was 24.8%.The mean leyth of hospital stay was 9.6 days(range 8-18) .Conclusion Our study showed that SHVE is a safe and effective procedurei and it is applicable to liver tumors near but not invade the inferior vena cava.

Results ①No one of 20 cases of gallbladder hyperplasia was found to express TNF mRNA, while 4 of 20 (20%) cases of dysplasia and 18 of 20 (90%) cases of carcinoma were found to express TNF mRNA (P

Objective To investigate the effects of positive end-expiratory pressure (PEEP) on hemodynamics and intra-abdominal pressure in patients with acute respiratory distress syndrome (ARDS) with normal intra-abdominal pressure (IAP) and intra-abdominal hypertension (IAH) during mechanical ventilation under a incremental PEEP.Methods Eighteen ARDS patients with normal IAP or IAH treated in intensive care unit of Anhui Provincial Hospital were enrolled for study.At different PEEP levels (5,10,15,20 cmH2O),hemodynamic parameters including extravascular lung water index (EVLWI),intrathoracic blood volume index (ITBVI),stroke volume variation (SVV) and IAP were measured with PICCO technology.Results Compared with ARDS patients with normal IAP,the ARDS patients with IAH were characterized by:(1) EVLWI was decreasing under the increment of PEEP,but there was no significant difference between 15 cmH2O and 20 cmH2O (t =0.593,P =0.572).As PEEP was gradually escalated,EWLVI had no significant changes in patients with normal IAP.(2) SVV increased as PEEP was being titrated to higher level in both groups but in normal IAP group such effect was observed till PEEP above 10cmH2O (PEEP5 vs.PEEP10,t=0.326,P=0.752; PEEP,10 vs.PEEP 15,t=-20.032,P＜ 0.01).(3) There was no statistical difference in ITBVI between two groups at varied levels of PEEP.(4) PEEP could increase IAP levels and had much more profound effects on patients with IAH.Conclusions PEEP is a contributing factor changing IAP.It is necessary to take the level of PEEP into account as IAP variation is interpreted in patients under mechanical ventilation.Different PEEP levels can significantly affect the EVLWI in patients with IAH but not do not in ones with nomal IAP.

Background and purpose:The impact of the two factors of von Willnbrang factor(vWF) and integrin?3 on tumor metastasis has not been recognized. This study was done to investigate the expression of vWF and integrin?3 in human lung cancer cell line H460,the association between the two factors and tumor metastasis effect of vWF and integrin?3 on adhesion of human lung cancer cell line H460. Methods:The expression of vWF and integrin ?3 protein was examined by immunohistochemical staining. The impact of vWF and integrin?3 on adherent effect of tumor cells was evaluated by adhesion experiment, antibody inhibiting experiment and MTT.Results:Positive expression of vWF and integrin?3 was detected in H460 human lung cancer cells. H460 human lung cancer cells were able to adhere to vWF. Using anti-integrin?3, we observed that the ability of cell adhesion to vWF was inhibited,and A Value decreased from 1.59?0.06 to 0.55?0.03(P=0.01619). Using anti-vWF, we observed cell adhesion to vWF was inhibited too and A Value decreased from 1.60?0.06 to 0.54?0.03(P=0.01598),which had the same effect when using anti-integrin?3.Conclusions:H460 human lung cancer cells are capable of producing vWF, and vWF expression contributes to metastasis by adhering to cancer cells, integrin?3 is the vWF receptor on H460 human lung cancer cells.
