BACKGROUND:Neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine can induce the clinical, biochemical and pathological characteristics similar to those observed in primary Parkinson’s disease. OBJECTIVE:To observe the effects of repetitive transcranial magnetic stimulation on the proliferation of endogenous neural stem cells of Parkinson’s disease model mice and the mood change.
METHODS:A total of 72 male C57BL/6J mice were randomly divided into four groups:normal saline group, Parkinson’s disease model group (model group), sham-repetitive transcranial magnetic stimulation group (sham group) and repetitive transcranial magnetic stimulation group. The mice received 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine injection×4 to establish acute Parkinson’s disease models. The mice in the normal saline group were injected the same volume saline. And 24 hours after the last injection of 1-methyl-4-phenyl-1,2,3, 6-tetrahydropyridine, the mice in the repetitive transcranial magnetic stimulation group received five trains of repetitive transcranial magnetic stimulation, 1 Hz for 25 seconds, at an intensity of 1 Tesla daily for 1, 3, 7 consecutive days. Sham group mice were not exposed to the magnetic field. No treatment was performed in the mice of model group. The mood change was evaluated using the elevated-plus maze testing before and after repetitive transcranial magnetic stimulation treatment. The change in expression of nestin in the subventricular zone was observed by using immunohistochemical technique.
RESULTS AND CONCLUSION:(1) Elevated-plus maze testing:There was no statistical significance about percentage of opening arm time accounting for total time among groups and at different time points in each group, but after stimulation, the percentage of opening arm time accounting for total time showed a declined tendency. (2) The results of nestin immunohistochemical staining:Compared to the normal saline group, the number of nestin-positive cells of the model group was increased at days 3 and 7, and there was no statistical significance in the number of nestin-positive cells between model group and sham group;Compared to the sham group and model group, the number of nestin-positive cells of repetitive transcranial magnetic stimulation group were evidently increased;The proliferation of endogenous neural stem cells was time-dependent, endogenous neural stem cells exhibited outward migration gradual y along the certain way, and some cells were able to migrate to the corpus cal osum at day 3, and even to the cerebral cortex at day 7. Repetitive transcranial magnetic stimulation can promote the endogenous neural stem cells in a time-depended manner.

Objective To learn the satisfaction and influencing factors of medical insurance for urban residents in Taiyuan city.Methods The multi-stage random sampling method was used to survey the satisfaction of medical insurance for urban residents so covered in 4 districts of Taiyuan city. The questionnaire covered basic personal information, and comments of the residents on the three dimensions of medical insurance regarding the stakeholders. The data solicited were subject to descriptive analysis, Kruskal-Wallis test and ordered multi-class logistic regression analysis. Results The rate of overall satisfaction of urban residents′ medical insurance in Taiyuan city was 44.6% , that of average satisfaction was 48.3% , and that of dissatisfaction was 7.1%.For residents of different family size and physical health status, the differences of their satisfaction were statistically different(P<0.05).Ordered multi-class logistic regression analysis showed that the proportion of reimbursement, the scope of drug treatment and the efficiency of treatment were top factors affecting their satisfaction ( OR > 1 ). Conclusions The rate of overall satisfaction of medical insurance by urban residents in Taiyuan city is low. To improve their satisfaction, it is important to increase the proportion of reimbursement, expand the scope of reimbursement for diagnosis and treatment along with drugs, simplify the reimbursement procedures, and improve the service attitude of the service agencies.
