Objective To evaluate the feasibility and efficacy of endoscopic push?radial dissection (EPRD)for benign esophageal stricture(BES). Methods Clinical data of 24 patients diagnosed as having BES who received EPRD were analyzed. The procedure and efficacy were evaluated. Results All 24 patients underwent EPRD successfully with mean operation time being 32 min(15?45 min).The mean esophageal stric?ture incision length was 3?? 2 cm (1?? 0?8?? 0 cm).No severe complications related to EPRD occurred, or trans?ferred for surgery. Patients were followed up for 1?5 months (mean 2?? 8 months). Dysphagia was relieved signif?icantly during the follow?up in 23 patients where endoscopy could go through smoothly. But dysphagia re?oc?curred in one patient 2 weeks after the operation, who underwent a second EPRD and stent implantation, then dysphagia was relieved. Conclusion EPRD is safe, feasible and effective for benign esophageal stricture.

Pharmaceutical excipients, as an indispensable part of drug preparation, play crucial roles as drug carriers, improving drug release, ensuring drug stability, and enhancing patient compliance. Traditional Chinese Medicine (TCM) boasts a rich developmental history. With the modernization of technology, the deep integration of pharmacy, chemistry, and materials science has provided broader opportunities for innovative research in TCM. Simultaneously, the demand for high-quality excipients has become increasingly critical.This paper aims to review current research and applications of excipients in TCM preparations, including pre-mixed and co-processed excipients, modified excipients, and the unification of drugs and excipients, such as flavoring agents, fillers, penetration enhancers, and delivery systems. A meticulous synthesis and analysis of existing research aims to provide a reference for selecting excipients in TCM preparations, stimulate innovation in excipient development for TCM, and advocate for the development of personalized excipients.

OBJECTIVETo study the secular trend and characteristics of infant mortality rate due to premature birth or low birth weight (IMRPL) in China from 1996 to 2013.

METHODSData used in this study was collected from the population-based Child's Health Surveillance Network of China. The Cochran-Armitage Trend test and Poisson regression were used to test the trend of IMRPL and explore the differences of the trend among different regions or areas.

RESULTSThe nationwide IMRPL was 629.9 per 100 000 live births in 1996 and it decreased to 214.6 per 100 000 live births in 2013. The average annual decline rate was 6.14%, while the proportion of infant mortality due to premature birth or low birth weight in all infant deaths was on the rise with the average annual growth rate of 1.52%. And the proportion increased to 22.6% in 2013. IMRPLin rural and urban areas fell 28.1% and 66.6% respectively during 1996 and 2013. But the differences between urban and rural areas was obvious. During the same period, the average IMRPLin the central region was 1.40 times (95%CI:1.31-1.49) of that in the eastern region. And the average IMRPL in the western region was 2.25 times (95%CI:2.12-2.40) of that in the eastern region. The differences among different regions was obvious. Male infant mortality rate due to premature birth or low birth weight was 1.09 times (95%CI:1.05-1.14) of that in female infant from 1996 to 2013.

CONCLUSIONThe risk of IMRPL decreased substantially in China from 1996 to 2013. And the risk of IMRPL decreased more in rural areas than that in urban areas. The differences among different regions and areas were obvious. Premature birth or low birth weight as one of main factors has become a serious threat for health of Chinese children.

Objective:To design a programmed evaluation process,and to explore its application effect in the management of medical equipment in emergency department.Methods:The information management platform was constructed based on IntelliJ IDEA and Java language with browser and server(B/S)architecture,a programmed evaluation process was designed to manage medical equipment in the emergency department.From 2021 to 2022,27 medical devices in use in the emergency department of Beijing Friendship Hospital,Capital Medical University were selected,the programmed evaluation process and the post-evaluation process were adopted respectively for management according to the different equipment management methods.A total of 800 equipment operation logs sampled were analyzed under the two management methods.The timeliness of equipment management,management effect and satisfaction scores of related management personnel were compared between the two management methods.Results:The average time consumption of equipment warning timeliness,timeliness of maintenance personnel's arrival and timeliness of proposed treatment methods in the programmed evaluation process management were(0.92±0.21)min,(5.43±1.08)min and(15.63±2.27)min,respectively,which were lower than those in post-evaluation process management method,the difference was statistically significant(t=13.810,16.893,16.554,P＜0.05).The failure rate of 400 logs sampled by the programmed evaluation process management method was 2.75%(11/400),which was lower than that of the post-evaluation process management method,the regular maintenance completion rate was 99.75%(399/400),which was higher than that of the post-evaluation process management method,the difference was statistically significant(x2=18.841,10.778,P＜0.05).The equipment maintenance time and equipment maintenance cost of the programmed evaluation process management were(9.32±1.18)days and CNY(201,600±50,500),respectively,which were lower than those of the post-evaluation process management method,and the difference was statistically significant(t=12.663,37.213,P＜0.05).The satisfaction scores of maintenance engineers,medical staff and patients in equipment use management for the programmed evaluation process management were(97.25±2.44),(98.63±4.57)and(97.16±3.09),respectively,which were higher than the post-evaluation process management method,and the differences were statistically significant(t=21.284,8.206,5.933,P＜0.05).Conclusion:The application of programmed evaluation process to the equipment management of emergency department of the hospital can effectively improve and make up for the loopholes and deficiencies in the conventional equipment management,improve the effect of equipment management,reduce the frequency of equipment failure,and ensure the safe and stable operation of equipment.
