ABSTRACT
Objective:To analyze the surgical methods of operable breast cancer and analyze the follow-up results.Methods:A retrospective analysis of the clinical and pathological data of 636 operable breast cancer patients admitted to Zibo First Hospital from July 2008 to April 2018, including the clinical stage, pathological staging. Analyze of the proportion of four surgical methods, and through follow-up, analyze the treatment effect of different surgical methods.Results:All patients are female, aged 26-80 years, the clinical stage of 636 patients: Tis 18 cases, stage Ⅰ 143 cases, stage Ⅱ 354 cases, stage Ⅲ 114 cases, stage Ⅳ 7 cases. There are four types of surgery: ① breast conserving surgery + sentinel lymph node biopsy in 124 cases (19.50%); ② breast conserving surgery + axillary lymph node dissection in 39 cases (6.13%); ③ mastectomy + sentinel lymph node biopsy in 163 cases (25.63%); ④ modified radical surgery in 310 cases (48.74%). Sentinel lymph node biopsy in 427 cases (67.14%), success in 404 patients (94.61%); all patients with lymph node negative 384 cases (60.38%). Follow-up for 1 to 9 years, 11 cases of local recurrence after breast-conserving surgery, It accounted for 6.75% of breast-conserving surgery; 43 cases of local recurrence of chest wall after mastectomy, accounting for mastectomy 9.09%; 33 cases of recurrence and metastasis of axillary lymph nodes and supraclavicular lymph nodes, 4 cases of axillary recurrence after sentinel lymph node biopsy.Conclusions:The proportion of breast-conserving surgery in this group of patients was high and the local recurrence rate of breast-conserving surgery was less than that of mastectomy group; the proportion of simple modified radical surgery declined further; patients with axillary lymph node metastasis were less in the whole group. The choice of reasonable operation method is an important factor to improve the prognosis of breast cancer.
ABSTRACT
Objective To investigate the correlation between the infiltration of tumor-associated macrophages (TAM) in breast cancer and the expressions of vascular endothelial growth factors (VEGF). Methods The expressions of CD163 (TAM marker) and VEGF in 45 postoperative tissue specimens of primary breast cancer in Affiliated Hospital of Guilin Medical University from January 2014 to January 2018 were examined by using immunohistochemistry EnVision method. Then TAM was counted under light microscope and the expression of VEGF was determined by using semi quantitative integration method. Correlation between the expression of TAM and VEGF and their relationships with clinicopathological parameters were also analyzed. Results TAM infiltration (the number of TAM under per high power field) in breast cancer patients (≤ 51 years old) was significantly more than that in breast cancer patients (> 51 years old) [(78.1±11.9)/HP vs. (69.7±14.0)/HP, t=2.167, P=0.036]. TAM infiltration in breast cancer patients with lymph node metastasis was more than that in breast cancer patients without lymph node metastasis [(79.2 ± 11.8)/HP vs. (70.2±13.6)/HP, t= 2.362, P= 0.023]. The positive rate of VEGF in breast cancer with lymph node metastasis was significantly higher than that in breast cancer without lymph node metastasis [100.00 ％(20/20) vs. 68.00％(17/25),χ2=5.749, P=0.017]. Pearson correlation analysis showed that the expression of VEGF was positively correlated with TAM infiltration (r 2 = 0.800, P< 0.05). Conclusion TAM infiltration and the expression of VEGF can be used to predict the malignant degree of breast cancer, and can be used as a potential intervention target for adjuvant therapy and clinical prognosis of breast cancer.
ABSTRACT
Objective To explore effect of decreasing blood lipid by mappianthus iodoies flavone in rats model.Methods We selected sixty healthy male SD rats,which were randomly divided into six groups:normal control group (NC),model control group (MC),simvastatin group positive control group (PC),low dose group of mappianthus iodoies flavonoids (MIF1 group),middle dose group of mappianthus iodoies flavonoids (MIF2 group),high dose group of mappianthus iodoies flavonoids (MIF3 group).After 6 weeks,absolute diet 12 h,the rats of blood samples were drawn from orbit and it was collected to detect serum total cholesterol (TC),serum triglyceride(TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C).After 12 weeks,absolute diet 12 h,get blood from heart,serum,centrifugal separation measure serum SOD,MDA content,test the content of T-AOC.Results Mappianthus iodoies flavonoids can decrease the level of TG,TC,LDL-C,MDA and improve HDL-C,SOD and T-AOC in lipid of lipidemia rats.Especially compared with the NC group,the level of TG,TC,LDL-C,MDA in MC group were in creased,and HDL-C,SOD,T-AOC level were decreased in rats fed high fat diet(P＜0.05),meanwhile the levels of TC,TG and LDL C in the treatment groups were decreased,and HDL-C levels were increased(P＜0.05);MIF group,which are compared with MC,the level of TC,TG,LDL-C and MDA weresignificantly decreased and the level of HDL-C,SOD,T-AOCwere increased significantly(P＜0.05).Conclusion Mappianthus iodoies flavone may improve the level of SOD,T-AOC and decrease the level of MDA to decrease lipid.
ABSTRACT
Objective To investigate the therapeutic effect of astragalus injection onβcells apoptosis of type 1 diabetes mice. Methods 32 mice were randomly divided into a control group, a diabetes group, a small dose group and a large dose group of astraglus. Except the control group, mice in the other 3 groups received intraperitoneal injection of STZ in order to induce diabetic mellitus. Then one week after injection of STZ, mice in the small dose group and the large dose group of astraglus were given 30, 60 g/(kg?d) doses of astragalus injection, while the other 2 groups were injected into an equal volume saline for 4 weeks. Serum NO, inducible nitric oxide synthase (iNOS) and insulin levels were detected by enzyme linked immunosorbent assay method, and apoptosis was measured by using a TUNEL assay. Results Compared with the diabetes group, the serum NO (25.81 ± 2.09μmol/L, 18.84 ± 3.95μmol/L vs. 30.34 ± 2.53μmol/L) and iNOS (21.38 ± 4.48μmol/L, 17.00 ± 3.05μmol/L vs. 26.62 ± 2.48μmol/L) levels were significantly reduced in the small dose group and the large dose group of astragalus (P0.05). Conclusion Astragalus injection can reduce the iNOS activity and NO production, but can not effectively decreasingβcells apoptosis.
