Metformin has become the first-line drug for the treatment of type 2 diabetes, which is stably efficacious, safe, and cheap. Previous studies have shown that the application of metformin can decrease the rate of tumor incidence, recurrence, and metasta-sis. It can also improve the prognosis of cancer patients and their lifetime after long-term use. Considering its multiple advantages, met-formin has become an emerging choice for the treatment and prevention of cancer. Therefore, the mechanisms through which metfor-min inhibits tumor metastasis in cancer therapy are worth investigating.

Objective To study the relationship between the expression of matrix metalloproteinase-9 in rat brain and pathogenesis of epilepsy.Methods The expression of matrix metalloproteinase-9 in hippocampus was observed by immunochemistry in normal and epilepsy rat.Meanwile,the effects of dexamethasone before epilepsy on the expression of MMP-9 in hippocampus was evaluated.Results The expression of MMP-9 in hippocampus were fewer in normal rat brain.The expression of MMP-9 had increased in hippocampus after epilepsy 24h.It had increased obviously in dentate gyrus(DG)after epilepsy 72h than 24h(P0.05).Dexamethasone suppressed the expression of MMP-9 in hippocampus.Conclusion The expression of MMP-9 in rat brain participates in immunopathogenesis of epilepsy by affecting brain immunoreaction,leading to the change of neuronal response and synapse remodeling in hippocampus,regulating brain nervous cell excitability.Dexamethasone plays a prominent suppressant role in the processes.

Objective To apply the feedback closed-loop management systemin the telephone follow-up service for discharged patients to increase patient satisfaction and improve the quality of nursing. Methods From January 2015,telephone return visit to discharged patients were analyzed, a summary of dissatisfaction events, analyze the causes every month. Then,the improvement measures for nursing quality were put forward and the effects were evaluated to form a closed-loop management system. Results After the application of feedback closed-loop management system,there was a significant difference in patients' satisfaction with nursing service between the first half (with the incidence of 91.77%,3657/3985) and the second half (with the incidence of 95.76%,3610/3770) of 2015 (χ2=52.22, P < 0.01). Of the 9 items of dissatisfaction recorded in the questionnaire, significant difference was observed in 8 items, as service attitude, hospitalizing education, personal care, question answering, nurse's operation, health education, respect, clean environment and the discharge instructions. The incidence of each item was 2.11%(84/3985), 0.23%(9/3985), 0.35%(14/3985), 0.33%(13/3985), 0.30%(12/3985), 2.99%(119/3985), 0.33%(13/3985), 0.58%(23/3985), 2.58%(103/3985) in the first half of 2015 respectively, compared to 1.09%(41/3770), 0.05%(2/3770), 0.05%(2/3770), 0.08%(3/3770), 0.21%(8/3770), 0.64%(24/3770), 0.85%(32/3770), 0.21%(8/3770), 1.25%(47/3770) in the second half of 2015 respectively (χ2=4.084-59.088,P<0.01 or 0.05). However, no significant difference was observed in the nurse operational between the first half (0.30%) and the second half (0.21%) in 2015 (χ2=0.596, P>0.05).
