Objective ERP research has always been the hot spot of the n~ve electrophysiology research.A gTowing body of research suggests that ERP can effectively reflect the cognitive function in patients with depression,evaluate the risk of suicide.This paper reviews the ERP related components with depression and related research.On the basis of the application of ERP in the depression research discusses limitations and prospects on the later development.Methods The articles were retrievaled from databases,such as P UBMED,Foreign medical information resources retrieval platform,CNKI,Wanfang database,ect,from 2013-06 to 2015-01.Index strategy TI:TI:[depression OR affective disorder] AND [suicide OR suicidal] All field:event related potential.Reading and narrowing the scope of the articles,we should understand the experimental design,such as Sample company have suicidal ideation and (or) behavior of patients with depression.Potential induced way,ERP related component detection method,etc.The articles included 43 in English and 15 in Chinese.Read the full text and retain nearly five years about depression and related literature.Results Eventually,the article includes 34 articles and 3 of in Chinese.Conclusion Associated with suicidal ideation and (or) behavior of the existing cognitive dysfunction in patients with depression,ERP related components such as:abnormal P300 and CNV,MMN.N400 have not found abnormal.This article only from the Angle of depression and related research are reviewed in this paper the characteristics of ERP,ERP of other mental illnesses among related research,and to be perfect in the future.

Objective To evaluate the clinical effects of intra arterial thrombolytic therapy for acute ischemic cerebral infarction and analize the factors influencing the clinical prognosis. Methods 32 patients were treated with intra arterial thrombolysis using urokinase(median dose, 65?10 4 U) within 2～20 hours, after the onset. The patient's condition was assessed by neurologists using National Institutes of Health Stroke Scale(NIHSS) score right at the admission. Clinical outcome was assessed after 3 months and graded as good for Modified Rankin Scale(MRS) scores of 0 to 3 and poor for MRS scores of 4 or 5 and death. Results Follow up cerebral angiography of 14 cases treated within 6 hours after onset showed complete/partial recanalization in 13 cases. Other 18 patients whose treatment started beyond 6 hours after onset outcame with complete/partial in 7. 20(62.5%) of the 32 patients had good outcome, 12(37.5%) had poor outcome and two patients(9.4%) died. Cerebral hemorrhage occurred in 2 of the 32 patients. Good outcome was associated with an initial NIHSS score of

Objective:To connect with the measurement data of asbestos dust fiber concentration in foreign countries, improve the accuracy of asbestos fiber detection in China, and understand the dust exposure in the working environment of asbestos and man-made mineral fiber production and processing sites in Zhejiang Province. The fiber count concentrations of working environment in glass fiber, ceramic fiber and asbestos processing plants were measured and compared.Methods:The dust concentration in the working environment of two glass fiber factories, one ceramic fiber factory and eight asbestos products processing factories was measured. The total dust mass concentration was measured according to GBZ/T 192.1-2007, and the fiber count concentration was measured by phase contrast microscope. Kruskal Wallis was used to test and compare the dust concentration in the working environment of each post. The correlation between asbestos mass concentration and fiber count concentration was analyzed by Spearman correlation.Results:Under the phase contrast microscope, there were many short and fine asbestos fibers in the field of vision, and there were many impurities around. The average dust concentration of asbestos processing plant was 3.2 f/ml, and the dust concentration of cotton ginning was the highest (6.68 f/ml) . There was a significantly positive correlation between asbestos fiber count concentration and mass concentration ( r=0.535, P=0.033) . The average fiber count concentration of glass fiber factory was 0.001 f/ml, and the highest was 0.005 f/ml. The average fiber count concentration of ceramic fiber factory was 0.001 f/ml, and the highest was 0.006 f/ml. Conclusion:The fiber count concentration in the working environment of asbestos factory in Zhejiang Province is obviously over the standard, which is one of the important reasons for the high incidence of mesothelioma in this area. Short and small asbestos fibers are easy to be ignored when counting. It is necessary to improve the actual operation process of fiber counting to form a laboratory standard in China.
