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 investigate the effect of extract of Ginkgo biloba(EGb) on levels of Endothelin-1(ET-1) and transforming growth factor ?1(TGF-?1) in renal tissue of diabetic rats.METHODS:Twenty-four male Sprague-Dawley rats were randomly divided into three groups:normal control group,diabetic model group and EGb-treated group.The levels of blood glucose,insulin,total cholesterol(TC),total triglycerides(TG),creatinine clearance(Ccr),urinary albumin excretion(UAE),and urinary ?2-MG were measured after 8-week corresponding treatment.Expression of SET-1,UET-1,and RET-1 was examined by radioimmunoassay technique.Expression of STGF-?1 and UTGF-?1 in serum and urine was examined by enzyme linked immunosorbent assay(ELISA).RESULTS:The concentrations of blood glucose,blood insulin,TC and TG increased significantly in diabetic group,which were down-regulated by EGb.Levels of ET-1 and TGF-?1.in both blood and urine and the ET-1 level in renal tissues were significantly higher in diabetic model group than in normal control group(P

In clinical nursing practice, ethnics dilemmas which nurses facing with are not usually a simple question of right and wrong or yes and no, but two or more mutual conflicts under some special circumstances; In order to help nurses to understand and deal with ethnics dilemmas effectively and reasonably, the authors summarize the four different ethnics dilemmas: the different ethical principles selection dilemma, the different stakeholder selection dilemma, the different interpersonal ethnics dilemmas and the conflict of the nursing professional ethics and the role morality. Typical cases of common ethnic dilemmas were summarized and analyzed in this paper.

Tumor necrosis factor-related apoptosis-inducing ligand(TRAIL) is a new anti-tumor biological agents which is very hot in recent years through its death receptor-induced apoptosis of tumor cells,and non-toxic to normal cells,and has synergy with the chemotherapy drug,but there is also resistance mechanisms.This article will review the biological characteristics of TRAIL and its receptors,TRAIL-induced apoptosis of tumor cells,as well as the mechanism of TRAIL in leukemia in the progress of treatment.

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 observe the clinical efficacy of acupuncture plus rehabilitation training in improving post-stroke dysphagia. Method A total of 60 patients with post-stroke dysphagia were randomized into a treatment group and a control group, 30 cases in each group. The two groups were intervened by basic treatment of internal medicine and swallowing rehabilitation training, and the treatment group was additionally given acupuncture treatment. The Standardized Swallowing Assessment (SSA), water swallowing test and Swallowing Quality of Life Questionnaire (SWAL-QOL) were evaluated in the two groups before and after the treatment. Result After the treatment, the SSA scores in the two groups were significantly decreased compared to those before the treatment (P<0.01), and the SWAL-QOL scores were significantly increased compared to those before the treatment (P<0.01); the SSA score in the treatment group was significantly lower than that in the control group (P<0.01), and the SWAL-QOL score was significantly higher than that in the control group (P<0.05). The water swallowing test classification after the treatment was significantly superior to that before the treatment in the treatment group (P<0.01), and there was a significant difference compared to that in the control group (P<0.05). Conclusion Acupuncture plus rehabilitation training can obviously improve the swallowing function of patients with post-stroke dysphagia, and the clinical efficacy was superior to single rehabilitation training.
