Objective To investigate the expressions of SOCS3 and IL‐6 in triple‐negative breast cancer(TNBC)and their clinical significance.Methods The expressions of SOCS3 and IL‐6 in TNBC and normal breast cells were detected by Western blot and fluorescence quantitative PCR.Immunohistochemical staining was used to detect their expressions in 84 TNBCs ,33 breast fibromas and 11 normal breast tissues. The correlation of their expressions in TNBC and the relationship between their expressions and clinical pathological parameters were analyzed as well.Results SOCS3 was not expressed or down‐expressed in TNBC cell lines while IL‐6 was over‐expressed. The positive rate of SOCS3 protein was 32.1% in TNBCs ,63.6% in breast fi‐bromas(P<0.01)and 72.7% in normal breast tissues (P< 0.01);and that of IL‐6 protein was 72.6% in TNBCs ,30.3% in breast fibromas(P< 0.01)and 27.3% in normal breast tissues (P< 0.01).Moreover ,a significant negative correlation was found between the expression of SOCS3 and that of IL‐6 in TNBC(rs = -0.590 ,P<0.01). The expressions of SOCS3 and IL‐6 were markedly associated with tumor size ,lymph node metastasis ,clinical stages and expressions of Ki‐67 and p53(P<0.05) , but not with age ,histological grades or menopausal status(P>0.05).Conclusion The expressions of SOCS3 and IL‐6 are asso‐ciated with the development of TNBC ,suggesting that SOCS3 and IL‐6 can serve as biological markers for evaluating the prog‐nosis ,and therapeutic targets of T NBC.

Objective To evaluate the impact of integrated information management platform on life style of diabetic patients. Methods A total of 84 diabetic patients were assigned to the intervention group and the control group by random digits table method with 42 cases each. All patients were in the hospital and after discharge given conventional three-tier management model. The intervention group was given comprehensive information management platform, three-tier management model mediated on this basis. The life style, fasting blood glucose, glycated hemoglobin were collected and compared between the two groups before and after intervention. Results After 9 months of intervention, the dietary pattern of the intervention group was more in line with the Chinese Dietetic Association's recommended dietary standard, in which staple food decreased from (343.90 ± 225.61) g before intervention to (311.71 ± 144.46) g, and meat decreased from (61.52 ± 59.73) g before intervention to (50.07 ± 36.16) g, and the lipid content decreased from (32.67 ± 21.31) g before intervention to (28.57 ± 19.52) g, compared with the control group (376.49 ± 129.58), (73.90 ± 55.15), (45.78 ± 20.03) g, there were significant differences(t =2.076, 2.278, 3.841, all P<0.05). The number of physical exercises increased from 30 before intervention to 37 cases, the number of moderate exercise increased from 12 cases before intervention to 20 cases, and the median of exercise scores increased from 11.000 (26.500) points before intervention to 33.000 (23.500) points, compared with the control group 15.000(18.000) points, there was significant differences (Z =3.687, P<0.01). The fasting blood glucose, glycated hemoglobin were (7.73 ± 1.31) mmol/L, (6.75 ±1.81)% after intervention and 8.000(2.200) mmol/L, 7.600(1.600)%before intervention in the intervention group, compared with the control group (8.60 ± 2.25) mmol/L, (8.81 ± 2.63)%, there were significant differences(t =2.111, 4.062, P<0.05 or 0.01). Conclusions Integrated information management platform management mode three-mediated diabetes may urge to improve the existing way of life, better control of blood sugar.

Objective To investigate the relationship between CD+3CD28+T cell value and chemotherapeutic efficacy in patients with advanced digestive cancer. Methods 38 digestive cancer patients with distant metastatic lesion were included.10 healthy persons were as control group. The absolute counts of CD+3CD28+T cell were measured with flow eytometry in these patients before chemotherapy. All patients received chemotherapy, gastric cancer: DCF regimen (docetaxel plus tegafur and cisplatin, one cycle), colorectal cancer:. Folfox regimen (L-OHP plus tegafur, two cycles), esophageal cancer: mitomycin plus tegafur and cisplatin (two cycles), gallbladder or pancreatic cancer: gemzar plus tegafur and cisplatin (one cycle). According to WHO standard, the chemotherapeutic efficacy was determined, 38 patients were divided into three groups: CR+PR (complete remission plus partial remission), SD (stable of disease) and PD (progress of disease) group. Statistical analysis was used upon all data. Results There was no significant difference in value of CD+3CD28+ T cell between CR+PR group and control group (P=0.549). The value of CD+3CD28+ T cell in SD group and PD group were significantly decreased (P=0.002, P=0.000). The value of CD+3CD28+T cell in CR+PR group was more than that in PD group (P =0.001), while in SD group was more than in PD group (P = 0.044). Conclusion The efficacy is poor, if the value of CD+3CD28+ T cell in patients with advanced digestive cancer is less than that of in healthy persons in peripheral blood. Therefore, the value of CD+3CD28+ T cell is important for the early prediction of the efficacy before chemotherapy.
