Transcranial magnetic stimulation (TMS) is a non-invasive technique that can activate cortical motor areas and the corticospinal tract without causing the subject discomfort. Since TMS was introduced, numerous applications of this technique have been developed for the evaluation of neurologic diseases. They allow the evaluation of cortex excitability and motor conduction in the central nervous system and have been proved useful in monitoring motor abnormalities and the recovery of motor function. TMS also gives informations on the pathophysiology of the processes underlying the various clinical conditions and contribute to investigate the mechanisms of diseases. In addition, therapeutic use in depression, Parkinson's disease, epilepsy, spinal cord injury and stroke has raised great interest over the past decade. Theapplication of TMS has great potential both as an investigational and as a therapeutical tool in neurology and psychiatry. However, as an infant techniology, there should be further investigation and large randomized trials to be conducted.

Objective: To observe the changes of plasma levels of omentin-1 and vaspin in patients with acute coronary syndrome (ACS). Methods: Our research included in 2 groups: ACS group, the patients with conifrmed diagnosis in our hospital from 2013-05 to 2013-09,n=100 including 52 male, 48 female and Control group, the patients with simultaneous coronary angiography excluded CAD,n=88. Plasma levels of omentin-1 and vaspin were examined by ELISA and the differences were compared between 2 groups. Results: Plasma levels of omentin-1 and vaspin in ACS group were lower than Control group (t=2.718,P<0.05) and (t=2.416,P<0.05). Correlation analysis presented that in ACS group, omentin-1 level was negatively related to total cholesterol (TC) (r=-0.702,P<0.05) and C-reactive protein (CRP) (r=-0.714,P<0.05); vaspin was negatively related to TC (r=-0.655, P<0.05) and CRP (r=-0.587,P<0.05); Omentin-1 was positively related to vaspin (r=0.643,P<0.05). Multiple linear stepwise regression analysis showed that plasma levels of omentin-1 and vaspin might be affected by CRP, TC and LDL-C. Conclusion: ACS patients had decreased plasma levels of omentin-1 and vaspin; in addition, omentin-1 and vaspin might be involved in lipid metabolism.
