Inflammation and lung function decline are the main pathophysiological features of chronic obstructive pulmonary disease (COPD). Acupuncture can improve lung function in patients with COPD, but the underlying mechanisms are not well understood. Orexins (OXs), which are found in peripheral plasma, are neuropeptides that regulate respiration and their levels are related to COPD. Therefore, we hypothesized that acupuncture might alter OXs, reduce lung inflammation and improve lung function in COPD.

Single-disease management is an important means of medical quality management, and data is the basis of single-disease management. Aiming at the problem of difficult data collection of single disease in hospital, the authors designed a solution to realize the fine management of single-disease data based on data center. The hospital optimized the data quality through overall management, unified the data collection source based on the data center, built a single-disease intelligent collection platform to complete the data collection, and calibrated the data to ensure its accuracy, so as to form a single-disease index management process and realize high-quality data collection. The average actual backfill rate was as high as 95.7%. On this basis, the hospital optimized the single-disease reporting and quality control management mode to further promote the fine management of medical quality.

As medical record management is key to hospital management, a hospital introduced paperless practice of automatic archiving in the following practices. Clarification and identification of the scope of business system transformation, establishment of an architecture integrating various business systems, integration platform, hospital data center, archiving system and certification authority, creation of three automatic archiving processes: initial archiving, late return archiving and modification archiving, for refined management of the review and tracking of archived medical records. Thanks to this paperless management, the automatic archiving rate was as high as 95.95%for medical records, 96.47%for laboratory reports and 99.58%for medical orders respectively. A full-process and whole-cycle informationized closed loop management was achieved for the collection, archiving, review and utilization of medical records, substantially upgrading hospital informationization and medical record management.

The application of big data and artificial intelligence technology in the medical field is key to hospital informatization. In October 2018, a tertiary hospital launched a clinical intelligent application platform. The platform took AI assistant as the carrier of intelligent application, supported the role expansion, function expansion and connotation expansion of intelligent application, and layed the foundation for the construction of clinical intelligence. As of July 2022, the platform had been embedded into the outpatient, emergency and inpatient business systems with the help of AI assistant, realizing such intelligent applications as auxiliary diagnosis, auxiliary treatment, risk warning, AI medical record quality control, research entry group and infectious disease management, as well as enriching the connotation of such specialty applications as orthopedics and ear, nose and throat. The platform satisfied the integration and integration of hospital information construction and provided convenient and effective intelligent auxiliary tools for clinical use.

Objective:To study the actual effect of the use of personal protective equipment of the examined individuals, and provide reference and basis for the correct use of personal protective equipment and the radiological health administrative law enforcement.Methods:From February to June 2022, the imaging department of Qingdao Municipal Hospital selected 170 patients who underwent X-ray imaging examination (oral panoramic, dental radiography, DR photography, CT scanning), including 25 with oral panoramic and dental radiography, 60 with CT scanning and 60 with DR imaging. The thermoluminescent dosimeter was used to detect the ambient dose equivalent at the point of concern for 170 examined individuals who have used personal protective equipment to cover their sensitive parts, and to analyze the data detected at the same point as above when routinely using the same equipment.Results:There was a statistically significant difference in the dose equivalent at the same points inside and outside the lead neckband ( t=-2.23, P<0.05). There was no statistically significant difference in the dose equivalent at the same point inside and outside the lead collar during dental radiography ( P>0.05). During DR photography (chest PA, lateral and lumbar AP), the examined individuals were wearing lead aprons. Among them, there was a statistically significant difference in the dose equivalent at the same points inside and outside the lead aprons of children′s chest PA and adults′ chest PA ( U=10.00, 19.00, P<0.05). There was no statistically significant difference in the dose equivalent at the same points inside and outside the lead aprons of adult′s chest PA and lumbar AP ( P>0.05). When performing CT scan (chest or upper abdomen), there was a statistically significant difference in the dose equivalent at the same points of wrapped lead aprons( U=878.50, 11.00, P<0.05). Conclusions:The correct use of personal protective equipment is a complex technical problem. It is very important to fully and accurately understand the optimization principle of radiation protection and correctly use personal protective equipment for the examined individuals. The administrative punishment of radiation health on the use of personal protective equipment of the examined individuals should be cautious.
