Objective:To construct an evaluation index system for the risk factors of peripheral venous indwelling catheter failure in adults.Methods:Through literature review, focus group interview method and Delphi method, an evaluation index system for risk factors of peripheral venous indwelling catheter failure in adults was established.Results:The recovery rate of the two round were both 100%; the authority coefficient was 0.939, the coordination coefficient was 0.452 and 0.315 respectively ( χ2=607.88, 502.45, P<0.05). Finally an evaluation index system for adult peripheral venous indwelling needle catheter failure risk factors including puncture factors, patient factors, indwelling needle placement factors, indwelling needle maitenance and withdrawal factors and 54 second-level indicators were formed. Conclusions:The construction of adult peripheral venous indwelling needle catheter failure risk factor assessment system is reasonable and comprehensive in content, which provides reference for clinical nurses to evaluate and prevent the failure of adult peripheral venous catheter failure.

OBJECTIVE To provide a reference for comprehensive quality evaluation and control of the effective parts of Dracocephalum moldavica （EPDM）. METHODS A total of 10 batches of EPDM were prepared， and chemical information of EPDM was collected by HPLC-Q-Exactive-MS. EPDM components were identified by literature search， database comparison and manual analysis. HPLC fingerprints of 10 batches of EPDM were established by using the Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprint （2004 A edition）； the similarity evaluation and common peak identification were carried out， and the contents of 5 index components were determined by HPLC. RESULTS A total of 11 compounds in EPDM were identified. The fingerprint similarities of EPDM samples from 10 batches were all above 0.96. Among 11 chromatographic peaks， 5 peaks were identified， such as luteolin-7-O-β-D-glucuronide（LG）， apigenin-7-O-glucuronide（APG）， rosmarinic acid（RA）， diosmetin-7-O-β-D-glucuronide（DG）， tilianin（TL） . The results of the quantitative analysis showed that all above 5 components had good linearity （R2≥0.999）， and the average recoveries were in the range of 95.12%-98.37%. The contents of LG， APG， RA， DG， TL were 21.268 3-29.243 9， 6.365 4-7.771 7， 37.327 4-45.671 2， 17.169 9-21.985 9， 66.940 4-91.206 3 mg/g， respectively. CONCLUSIONS The established method of component identification， fingerprint and content determination is stable， feasible and reliable， which is suitable for the comprehensive quality evaluation and control of EPDM.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.
