ObjectiveTo explore puncture point and angle of skin for unipedicular vertebroplasty by imaging measurement and combining clinical practice in order to pr vide reference for clinical work.MethodsCT images of thoracic and lumbar vertebrae of imaged with multislice helical CT were random chosen.From high to low position vertebrae of easy fracture T6 to -L5,its angle between vertebraI pedfcle stalk line and 1/3 of vertebraI body stalk line fore and median of point of intersection was measured.The angle of sternocostal joints route was also measured.At the same time the distance between site of skin puncture and spinous process was measured.ResultsThe angle between the thoracic vertebraI pedicle and sagittal section was (28.2 ± 3.8) °,the lateral distance of the spinous process was ( 31.6 ± 5.4) mm.The angle of thoracic vertebraI pedicle lateral route was (35 ± 3.4) °,the distance was ( 55.2 ± 5.3 ) mm.In the lumbar vertebrae pedicle route,the angle of L1 -L4 was (29.3 ± 5.6 ) °,the distance was (38.4 ± 4.5 )mm.Ls was (39.2 ± 3.3) °,the distance was ( 71.6 ± 6.2) mm.Combining clinical practice,the lateral distance of the spinous process in thoracic vertebraIpedicle route,the best puncture point was 30 mm,in thoracic vertebraI pedicle lateral route it was 40 mm,in L1-L4 it was 45 mm,in L5 it was 60 mm.ConclusionsThe unipedicular vertebroplasty can be performed rapidly,accurately and safely,and it reduces complications,cost and time.

Objective:To build a performance appraisal system for full-time researchers in specialized children′s hospitals, so as to mobilize their enthusiasm and improve their efficiency of scientific and technological output.Methods:Based on structure-process-result model, the library of indexes was initialized by such means as literature review and talent performance appraisal management experiences. From November 2020 to March 2021, Delphi method was adopted to finalize the appraisal indexes and weight of each index, while the quantifiable standards of the indexes were formulated by brainstorming, hence establishing the performance appraisal model index system for these researchers. Using both the new model and the original performance appraisal system of the hospital respectively, five full-time research staffs of research-oriented children′s hospital were selected for an empirical research on performance appraisal.Results:Fifteen experts carried out two rounds of Delphi research, finalizing a performance appraisal model for these researchers. The model comprises 3 level-1 indexes, 8 level-2 indexes and 23 level-3 indexes. Among them, the weight of scientific research output, scientific research process and scientific research investment of level-1 indexes were 0.507, 0.267 and 0.226, respectively. Empirical research showed that compared with the original appraisal indexes, the results of the new performance appraisal model were more targeted, enabling the research team to identify setbacks.Conclusions:The indexes set in the model built in this study prove more scientific, objective, and more reasonable in weight assignment. Such indexes can positively motivate and encourage the researchers, promoting the clinical-basic research integration, as well as the disciplinary development and research talent cultivation of the hospital.

Objective The purpose of this article is to summarize and review the current status of the construction of clinical research evaluation systems in domestic public hospitals,identify existing problems in the evaluation system,and propose development strategies and suggestions.Methods Retrieved relevant articles,dissertations and policies from the past five years(2018-2022),screened the titles,viewed the full texts of 52 selected papers and their references,and summarized them.Results The"five-only"indicators have long been an important indicator for evaluating clinical research in public hospitals,but in today's scientific research environment and policy environment,the"five-only"evaluation system has revealed its utilitarian draw-backs and gradually evolved into a hindrance to scientific research.It is urgent to break through the"five-only"orientation and establish a clinical research evaluation system oriented towards"transforming and applying transformation of scientific research achievements".Conclusion The evaluation system for clinical research should break the previous"five-only"evaluation model based on quantity-oriented scientific research evaluation.We can draw on the framework of the research output,influence,and environment indicators in the UK's REF Excellence Framework model,combine the American APT system and the Chinese STEM indicator dimensions,explore multi-outcome evaluation,integrate developmental indicators,and continuously improve the indica-tor system and application methods in practice to promote the development of clinical research in public hospitals.
