Objective To confirm the diagnostic value of DWI in superacute cerebral infarction and analyze the prognostic value of the volume of ischemic lesions on superacute DWI scans.

目的 明确弥散加权成像对超急性期脑梗塞的诊断价值，探讨DWI缺血损伤体积与预后的关系。

Methods Both conventional MRI and DWI were performed in 27 patients with superacute cerebral infarction. The MRI observations were carried out consecutively at acute (6-72 h), subacute (3-14 d) and chronic (15-30 d) stages to investigate the dynamic changes of the infarction. The change in signal intensity of the infarct lesions on DWI was observed.

对27例临床确诊的超急性期脑梗死患者行常规磁共振和弥散加权成像扫描，并分别于脑梗死的急性期(6~72h)、亚急性期（4~14天）和慢性期（15~30天）进行3次磁共振随访，观察脑梗死后不同时间DWI信号强度的变化。

By synthesizing theories of systems engineering, science of talent, talent assessment, performance appraisal and bibliometrics, the author analyzes the qualification structure and performance structure of theachers in military academies and sets up a basic structure and concrete appraisal indicator system of qualifications of technical specialty for teachers in colleges. The author puts forward new appraisal indicators such as "lecuring hours coefficient","republication coefficient","thesis of core journals coefficient" and "citation coefficient". Comparatively complete quantification approaches are invented by the author for working performance of teaching, researching and social service of teachers. Based on this, the author establishes an integrated method to generate the appraisal results. By the application of stadardized processing on the appraisal results and synthetization of weighted indexes, the author solves the addibility and comparability problems of differentiated appraisal results by category or dimensiok, and realizes the amalgamation and comprehensive appraisal of inflexible appraisalresults and flexible appraisal results, and probes into the testification methods of validity, consistency and sensitivity analysis for the indicators system.
