Grounding impedance measurement is a traditional proficiency testing programs, 2014 proficiency testing program on the basis of original ability to verify, combined with actual detection need, innovation introduced two verification point of the power input socket and metal plane testing. This paper analyzes and discusses the results of the ability verification in 2014, and puts forward the points of attention and the recommended method of metal plane test.

Objective To analyze the risk factors of post-stroke disability in patients with acute cerebral infarction.Methods Total 1 137 consecutive patients with acute cerebral infarction admitted in Department of Neurology, General Hospital of Jinan Military Region, were prospectively recruited from August 2010 to August 2014.According to Oxfordshire Community Stroke Project(OCSP), 275 patients were classified as total anterior circulation infarction, 377 as partial anterior circulation infarction,305 as posterior circulation infarction and 180 as lacunar infarction.The baseline data including age, gender, National Institute of Health Stroke Scale ( NIHSS) score were recorded.Recovery was assessed by modified Rankin Scale ( mRS) 6 months after stroke by telephone interview ( mRS≤2:good prognosis, 2

Objective The scale lists applied in the diagnosis and treatment of heat stroke generally draw on other specialty scales, and there is no specific scoring system on heat stroke verified by large-scale clinical trials.The paper compared common acute physiology and chronic health evaluationⅡ( APACHEⅡ) , dissolved inorganic carbon score( DIC score) , multiple organ dysfunction score( MOD score) for the prognostic evaluation of heat stroke patients, the sum of three scores and the sum of the percentages of three scores to the score sum on prognostic evaluation of heat stroke patients in order to find a scoring method with higher clinical value. Methods APACHEⅡ, MOD score, DIC score, the sum of three scores and the sum of three scores were applied on 43 patients with heat stroke admitted in our neurological intensive care unit ( NICU) or in intensive care unit ( ICU) .The analysis of the area under the receiver operating characteristic ( ROC) curve( AUC) analysis was made among five scores. Results The weighted sum of three scores has the largest AUC ( 0.896 ) in predicting the death of HS patients according to AUC.The optimal MOD score was 5.5 in predicting the death of HS with a sensitivity of 72.7%and a specifici-ty of 99.69%.The optimal DIC score was 1.5 in predicting the death of HS with a sensitivity of 100%and a specificity of 56.2%.The op-timal score of the sum of the percentages of three scores to the score sum was 0.727 in predicting the death of HS with a sensitivity of 72.7%and a specificity of 100%. Conclusion All the five scores can predict the prognosis of patients with heat stroke.However, due to the deficiency in the prognosis value, a more specific scoring system needs to be developed.
