Objective To independently design a protective restraint band used for the interventional catheter bed and to evaluate its application effect.Methods The self-designed restraint belt consisted of a restraint belt body,first movable band and second movable band.A total of 200 patients,who received interventional operation at the Affiliated Run Run Shaw Hospital,School of Medicine of Zhejiang University of China from October 2022 to March 2023,were collected for this study.The patients were divided into the study group(n=100,using the self-designed restraint belt)and the control group(n=100,not using the self-designed restraint belt).The duration of surgical interruption due to patient's factors and the incidence of restraint belt-related adverse events were compared between the two groups.Results The duration of surgical interruption of the study group was(0.26±0.12)min,which was significantly shorter than(1.46±0.50)min in the control group,the difference was statistically significant(t=-23.570,P＜0.01).The incidence of restraint belt-related adverse events in the study group and the control group was 0％and 7％respectively,the difference was statistically significant(x2=6.380,P=0.012).Conclusion The protective restraint band used for the interventional catheter bed can reduce the incidence of restraint belt-related adverse events and improve surgical efficiency.

To look into the cited literatures in Medical Journal of Chinese People's Liberation Army, all citations, including its quantity, type, language and period, in journals from 1996 to 2000 was investigated. Results: The average quantity of citations was 4 59. The citations from periodical accounted for 95 62%. The citations in Chinese and English accounted for 99 64%.The citations from 1980 to 1999 accounted for 97 35%. The results suggested that the average quantity of citations was very little. The literatures of other languages and special citations should be used more.

To find out the situations of the authors who published articles in Medical Journal of Chinese People's Liberation Army in 1996～2000, the number of authors, types of collaborated articles, organizations where the authors work were investigated. The average number of authors per article was 4.64, the collaboration rate was 93 95%, most of the collaborated articles were writen by authors working in a same organization 69 54%, trans provincial collaborated articles accounted for 15 86%, collaborated articles in a same province and internationally collaborated articles accounted for 13 03% and 1 57% respectively. The results suggested that the average number of citations was very small, and the scope of contributions should be extended in order to offer more opportunities for younger authors and to increase international collaboration.
