Objective:To explore the effects of VEGF and CD44V6 on breast cancer MCF-7 cells by NDGA.Methods:MCF-7 cells in the logarithmic growth state were selected and measured.There were four cell groups(concentration:0,1,10,100?mol/L)in the experiment.After 48h treatment of NDGA,the expression of VEGFmRNA was measured by RT-PCR and the expression of CD44V6 was examined by flow cytometry.Results:After treatment of NDGA,the expressions of VEGFmRNA and CD44V6 in NDGA groups were significantly lower than that of the control group(F=2996.13,P

Purpose:To explore the possibility of non-sent inel lymph node (NSN) metastases in early breast carcinoma patients with positi ve sentinel lymph node (SLN) and its clinical significance. Methods:The incidence and related clinical factors of NSN metas tases were analyzed in 84 early breast carcinoma patients with positive sentinel lymph node, who underwent radical mastectomy. Results:The metastatic NSN was identified in 41 of the 84 pati ents with positive sentinel lymph node (48.8%), the incidence of NSN metastases was related to primary tumor size, SLN metastatic focus size and HER-2 expressi on status, the incidence rate of NSN metastases is proportional to the size of t he primary tumor and metastatic SLN focus, patients with positive HER-2 expres sion have a high NSN metastases rate. Conclusions:The early breast carcinoma patients with

Objective To investigate the expression of FHITmRNA and WWOXmRNA in human breast cancer tissues and its relation to clinicopathological and other molecular parameters. Methods With reference to the expression of ?-actin,the expression of FHITmRNA and WWOXmRNA was determined by reverse (transcription)-polymerase chain reaction(RT-PCR) in 51 breast cancer and adjacent breast tissue, and (semi-quantitative) analysis of band densities was performed. The protein expression of estrogen receptor(ER), progesterone receptor (PR), Her-2 gene in the 51 breast cancer lesions was detected by (immunohistochemical) method. Results FHITmRNA and WWOXmRNA expression was significantly different in 54 breast cancer tissue compared to adjacent breast tissue (P0.05); of FHITmRNA and WWOX mRNA was related to axillary lymph node metastasis (P

Objective To investigate the interrelated liver damage and hepatitis B virus infection among breast cancer patients after chemotherapy, to provide guidance for future breast reduction combined hepatitis B virus infection after chemotherapy liver damage.Methods120 cases of breast cancer patients undergoing chemotherapy combined hepatitis B carries from June 2012 to November 2016 in ningbo women and children's hospital were selected as the research object, depending on whether the infection with the hepatitis B virus into the study group and the control group, the study group HBV-DNA, HBsAg are positive, totaling 62 cases;control group, HBV-DNA, HBsAg were negative, totaling 58 cases;compare two groups of patients after chemotherapy in cases of liver damage.ResultsThe study group after chemotherapy, the incidence of liver dysfunction 48.28% in the control group after chemotherapy, the incidence of liver dysfunction 6.45 percent, the study group after chemotherapy, the incidence of liver dysfunction was significantly lower than the control group, the difference was statistically significant (P<0.05).Study group Ⅰ liver damage degree, degree Ⅱ, degree Ⅲ, degree Ⅳ of apparent higher, the difference was statistically significant (P<0.05), antiviral therapy 20 cases, no antiviral treatment in 42 cases.Antiviral therapy HBV reactivation rate and incidence of liver dysfunction were 5.0%, 20.0%;no antiretroviral therapy in HBV reactivation rate and the incidence of liver dysfunction 31.0%, 52.4% respectively;HBV antiviral therapy re-activation rate and the occurrence of liver dysfunction were significantly lower than not antiviral therapy, and the data were statistically significant (P<0.05).ConclusionThe clinical having close links between liver damage and breast cancer combined hepatitis B virus infection with hepatitis B virus are more likely to occur after infection liver dysfunction chemotherapy, and breast cancer patients after chemotherapy.

Objective: To investigate the enhancing effect of ?-interferon on anticancer effect of tamoxifen against breast cancer cells in vitro. Methods: ER-positive MCF-7 and ER-negative MDA-MB-231 breast cancer cell lines were treated with tamoxifen alone, or in combination with ?-interferon or estrogen in vitro. Cell proliferation was evaluated by MTT assay; distribution of cell cycle was determined by flow cytometry( FCM) and cell apoptosis was determined by DNA gel electrophoresis and FCM. Results: Tamoxifen inhibited the growth of ER-negtive and-positive brest cancer cells, induced G0/G1 phase arrest and induced cell apoptosis. Tamoxifen at same concentration had stronger inhibitory effect on ER-positive cells than ER-negative ones. Promoting effect of estrogen on MCF-7 growth was blocked by TAM, but inhibition of MDA-MB-231 by TAM was not related to estrogen. Anticancer effect of TAM was enhanced when cells were pre-treated with ?-interferon for 24 h. Conclusion: TAM exerts its anti-cancer effect through inhibiting proliferation and inducing apoptosis of ER-positive/negative breast cancer cells in vitro, and ?-interferon can enhance this manticancer effect of TAM on breast cancer cells.

Objective To study the expression of BRMS1mRNA in human breast cancer tissues and their significance.Methods The expression of BRMS1mRNA was detected by reverse transcription-polymerase chain reaction(RT-PCR) in 71 breast cancer tissues and adjacent breast tissues,12 patients with benign breast tumors and 12 patients with normal breast tissue,and semi-quantitative analysis of band densities was also performed.Results The expression of BRMS1mRNA in 71 patients with breast cancer and adjacent breast tissue was 0.378?0.046 and 0.918?0.044,respectively;the expression of BRMS1mRNA in 12 patients with benign breast tumors and 12 patients with normal breast tissue was 0.908?0.047 and 0.934?0.028 respectively.BRMS1mRNA expression was significantly lower in breast cancer tissue compared to adjacent breast tissue,benign breast tumors and normal breast tissue(P0.05),but was related to axillary lymph node metastasis and clinical stage(P

Objective To analyze the clinicopathologic characterizations and patients prognosis of basal-like breast cancer. Methods The clinicopathologic eharacterizations,patient 5 year disease-free survival rate and overall survival rate of 25 basal-like breast cancer patients were compared with 34 CerbB2 overexpressing subtype and 37 ER positive subtype breast cancer patients admitted in our hospital in the same period. Results Patients of basal-like breast cancer accounted for 15.7% of all patients admitted.Compared with CerbB2 over-expressing subtype(29.4%)and ER positive subtype(35.1%),basal-like breast cancer patients were eider with 56.0% being≥50 years old(P＜0.05).Basal-like subtype breast cancer was larger in tumor size than ER positive subtype(P＜0.05),56% of basal-like subtype were of poor-differentiated grade pathologically compared with 18% in CerbB2 overexpression type and 16% in ER positive subtype respectively. Meanwhile, axillary lymph node metastasis was hishbar in CerbB2 overexpressing and ER positive subtype(64.7%,64.9%)than that of basal-like subtype(40.0%).Most visceral metastases were found in basal-like and CerbB2 subtype,but there were more local lymph node and bone metastases in ER positive subtype.Five year overall survoval rate of CerbB2 overexpressing subtype (48.5%)and basal-like subtype breast cancer patients(44.1%)were poorer than that of ER positive subtype(83.8%).respectively;However,there was no difference in 5 year disease-free surviVal rate between the three subtypes(42.7%,40.4%,58.3%,respectively).Conclusions Similar to CerbB2 over-expressing subtype.tlle clinicopathologic characterization and prognosis in basal-like breast cancer are poorer than that in ER positive subtype.
