OBJECTIVE To establish a hospital preparation cost item library， providing a reference for the refined accounting management of preparation costs in medical institutions. METHODS Based on literature analysis and practical work experience， a preliminary list of cost items was drafted. The Delphi method was employed to screen and optimize the items by analyzing the questionnaire recovery rate， expert authority coefficient， item importance score， coefficient of variation， and Kendall’s W of concordance. RESULTS The questionnaire recovery rates for the two rounds of expert consultation were 95.7% and 100%， respectively； the expert authority coefficients were 0.937 and 0.939， respectively； Kendall’s W of concordance were statistically significant （ P ＜0.001）. The finally established hospital preparation cost item library included 6 first-level items （such as raw material and packaging material costs， human resource costs， and production operation costs） and 29 second-level items （including main drug raw material costs， production personnel compensation， and finished product full-item testing costs）， comprehensively covering dimensions such as raw materials and packaging materials， fixed asset depreciation and equipment maintenance， human resources， production operations， energy and environment， and R & D and other costs. CONCLUSIONS This study successfully establishes a scientific and reliable cost item library for medical institution preparations， which can guide institutions to itemize actual expenditures， provide structured evidence for autonomous pricing， and support data needs for the formulation of insurance access and payment policies for innovative preparations.

【Objective】 To establish a postoperative recovery scale for Chinese people and to make a preliminary assessment for the scale.【Methods】Programmatic decision-making method was used to establish the basic items and structure of the scale.And then 70 postoperative patients were sampled to assess the scale by grading their recovery.【Results】The postoperative recovery scale had a good validity in contents and structure,and a good reliability and responsiveness.【Conclusion】The postoperative recovery scale established preliminarily can be used as the initial scale for evaluating the recovery of postoperative patients treated by traditional Chinese and western medicine.

Objective To prepare for extraction of liver focal lesion in view of its characteristics of images. Methods A region of interest in the liver region comprising the focal lesion to create a local image was selected firstly, then the threshold to pre-segment the local image was got automatically by using local OTSU in clusters algorithm, at last mark sifting methods to get red of inner holes and outer dissociate areas to get the final contour was used. Results The algorithm can efficiently extract the focal liver lesion. Conclusion The way of extraction of liver focal lesions with local OTSU and zone market screening is rapid and effective.

Objective:To study the relationship between an interpersonal climate of universities and teachers' mental health by self-made Scale of Interpersonal Climate (SIC).Methods:532 teachers from 16 universities all over the country were randomly chosen and assessed with SRHMS and SIC.Results: ①The better interpersonal climates of universities covered around 68.8% ; the most harmonious interpersonal relationships covered 72.4% ; worse interpersonal attitude, worse interpersonal interaction and worse interpersonal distance covered 44.5%,44.5% and 46.1% respectively ; the general feelings towards mental health of teachers in universities were better (the bad self-assessment、the medium self-assessment and better self-assessment are 9.0%,56.1% and 34.9% respectively ) . ② There was prominent positive correlation between universities' interpersonal climate and teachers' mental health(r=0.44). Meanwhile there was prominent negative correlation between negative emotion and interpersonal interaction, interpersonal harmony and interpersonal attitude(r=-0.25,-0.30,-0.30), but there was prominent positive correlation between negative emotion and interpersonal distance(r=0.24). ③ There was very distinct regression between interpersonal interaction and mental health, interpersonal harmony and mental health(?=0.28、0.22).Conclusions: The general feelings towards mental health of teachers in universities are better;There are close relationships between interpersonal climates of universities and teachers' mental health, and interpersonal interaction and interpersonal harmony play a brilliant role in mental health regression , they are the positive predictable factors to teachers' mental health.
