Objective To compare the long-term outcome between breast-conserving therapy with mastectomy therapy for early stage invasive breast cancer through a Meta analysis of the randomized controlled trials published worldwide.Methods Cochrane systematic evaluation was used to search through Cochrane libraries of clinical comparative trials,PubMed,Embase,Cancer Lit,and so on.The quality of literatures was independently evaluated and cross-checked by two evaluators,indicators for assessment including death number at the end of follow-up,locoregional and total recurrence.The results were analyzed with RevMan 4.2.2 software.Results Six articles were involved in the Meta analysis with total 3 933 patients.No statistical difference was found in the death at the end of follow-up between breast-conserving therapy group and mastectomy therapy group(OR=1.05,95% CI=0.93-1.19,P=0.45).Locoregional and total recurrence rate of breast-conserving therapy group were statistical higher than those in mastectomy therapy group(OR=1.64,95% CI:1.10-2.44,P=0.01;OR=1.42,95% CI:1.22-1.64,P

Objective To investigate the effect of empowerment education on self-management in patients with diabetes mellitus. Methods A total of 128 patients with diabetes mellitus who met the criteria of WHO in 1999 were selected and divided into the control group(62 cases)and the observation group(66 cases). The control group accepted the traditional nursing methods, and the observation group accepted the empowerment education model. FBG, PBG, HbA1c and Diabetes Management Self-efficacy Scale (C-DMSES) were compared between two groups of patients after 3 months and 6 months. Results After the intervention with the empowerment education model, the patient′s FBG, PBG, HBA1c of the control group were (7.69±4.21) mmol/L, (11.78±3.21) mmol/L, (7.95±1.46)%three months after discharge, and (7.21 ± 3.19) mmol/L, (10.48 ± 4.65) mmol/L, (9.15 ± 2.36)% six months after discharge; while in the observation group, FBG, PBG, HBA1c were (6.23 ± 3.59) mmol/L,(9.32 ± 4.06) mmol/L, (6.69 ± 1.10)%three months after discharge, and (6.15 ± 1.89) mmol/L,(7.33 ± 2.10) mmol/L,(6.02 ± 2.17)%. The differences between two groups were significant (t=2.012-5.196, P<0.05). C-DMSES scores of the control group were 103.48 ± 18.41, 134.38 ± 13.01 on admission and six months after discharge, while in the observation they were 102.83 ± 10.91,157.64 ± 19.56. The differences between two groups were significant (t=3.151, P<0.05). Conclusions Empowerment education model can improve the ability of self-management of diabetes patients, improve self-efficacy to improve their own ability to control blood glucose.

The aim of this study is to investigate the apoptotic inhibition and its molecular mechanism of dexamethasone (DEX) acting on cisplatin (CDDP)-induced apoptosis of human lung adenocarcinoma cell SPC-A1; SPC-A1 cells were pre-cultured in vitro for 24 hours with DEX in different concentrations and then CDDP was added in different concentrations for culturing for further 48 hours. The survival rates of the cells were determined by MTT. The expression of serum/glucocorticoid-induced kinase (SGK-1) and mitogen-activated protein kinase phosphatase-1 (MKP-1) in SPC-A1 cells after being cultured by 1 micromol/l DEX at different time was detected by semi-quantitative RT-PCR technology. The expression of glucocorticoid receptor (GR) in SPC-A1 cells was measured by immunohistochemistry (IHC) with biotin-labeled anti-GR. The results of MTT showed that SPC-A1 cells had resistance to CDDP-induced apoptosis with pre-cultured DEX and the resistance intensity presented DEX concentration-dependent. The expressing quantity of SGK-1 in SPC-A1 cells stimulated by DEX could be elevated and increased with intention of time, but the express of MKP-1 was not detected. Up-regulated expression of GR in SPC-A1 cells stimulated by DEX was detected by IHC. The number of cells expressing GR in SPC-A1 cells was significantly higher than that in the control group. The results showed that DEX inhibited apoptosis of SPC-A1 cells induced by CDDP. The possible molecular mechanism is that elevated expression of GR induced by DEX up-regulates the expression of SGK-1 which locates at the downstream of anti-apoptosis pathway. The apoptosis resistance of SPC-A1 cells may account for all above the factors.
