【摘要】 目的 了解学生对医院感染职业防护的基础知识的认知程度和学习需求。 方法 2010年3月采用自行设计问卷，对参加《医院感染与职业防护》课程学习的医学学生进行摸底调查。 结果 92.73%不知道标准预防措施和锐器伤后的正确处理方法及补救措施；27.27%不知道抽血时应戴手套；25.45%不清楚医务人员“六步洗手法”；90.91%不知晓工作服应交医院统一洗涤。 结论 学生防护知识薄弱，防护行为不全面、不规范。教学应重点帮助学生树立标准预防观念，掌握正确职业防护知识，在临床工作中以避免和减少各种危险因素的侵袭。【Abstract】 Objective To examine and evaluate the students’ knowledge and needs in studying hospital infection control and occupational protection. Methods Using a self-designed questionnaire in March 2010, we did a survey on students who attended the course of hospital infection control and occupational protection. Results Among all the students, 92.73% did not know standard prevention measures, and the correct treatment and remedial measures for sharp injuries; 27.27% did not know gloves should be worn at the time of blood drawing; 25.45% did not know the "six-step" hand-washing; and less than one out of ten students used hospital laundry to wash their uniform. Conclusions The students have a low level of relevant knowledge on occupational protection, and their protection behaviors were not complete or standard. Therefore, the teaching should help and support students to have a concept of standard prevention, and acquire sound knowledge and behavior of occupational protection in order to avoid and reduce the risk factors from their future clinical practices.
ObjectiveTo explore the appropriate intervention measures to reduce the influence of drug repercussion by pediatric hospital inpatients on nursing work. MethodBetween March 1st and 28th, 2014, statistical analysis on the characteristics of pediatric drug-return by drug repercussion questionnaires was carried out. ResultsEach drug repercussion took much time of the nurses (median of 5.00 minutes per time). The frequency of drug repercussion in the internal medicine department was more than that in the surgical department; the most drug repercussions were found in the respiratory medicine department, reaching 26.84%. The main category of drug repercussion was aerosolized medication (39.32%). The drug repercussion mainly resulted from lack of patients' education and doctor-related administration, which had a proportion of 31.44% and 27.19%, respectively. ConclusionsThe wards which have more drug repercussions should be under the supervision according to the analysis of drug repercussion. Meanwhile, improving patients' education and training of medical staff can reduce the pediatric hospital inpatients' drug repercussion and also may reduce the bad effects on nursing work.
To standardize and improve the reporting quality of digital health implementation research, the Geneva Digital Health Hub has developed the guidelines and checklist for reporting digital health implementations (iCHECK-DH). This paper introduces the background of iCHECK-DH and based on practical application experiences, emphasizes the importance of interdisciplinary collaboration. It focuses on economic cost-effectiveness and local policy guidance in the clinical implementation of digital health technologies. This will provide valuable insights for Chinese scholars when writing implementation reports on digital health technologies.
Pyroptosis is an inflammatory form of programmed cell death, including canonical and non-canonical pyroptosis pathway. Studies on pyroptosis have been reported in a variety of retinal diseases, but they are more focused on common diseases such as diabetic retinopathy and age-related macular degeneration. Many retinal diseases are difficult to treat because of the complexity of their etiology and pathogenesis. The discovery of pyroptosis has brought new content to the pathogenesis of these diseases, and also pointed a new direction for the treatment. Pyroptosis does not occur independently, and it is related to apoptosis and autophagy, but the specific mechanism is not clear. However, the most important biomolecule in the process of pyroptosis have been basically determined, and some methods can be used to interfere with pyroptosis, which has obtained preliminary achievement, suggesting that inhibition of pyroptosis may be a new direction for the treatment of retinal diseases and has broad research prospects.
The present paper is to evaluate the scientific research level and development trends of biomedical engineering in China using metrology analysis on Chinese biomedical engineering scientific literatures. Pubmed is used to search the biomedical engineering publications in recent 5 years which are indexed by Science Citation Index, and the number and cited times of these publications and the impact factor of the journals are analyzed. The results show that comparing with the world, although the number of the publication in China has increased in recent 5 years, there is still much room for improvement. Among Chinese mainland, Hongkong and Taiwan, Chinese mainland maintains the obvious advantage in this subject, but Hongkong has the highest average cited number. Shanghai and Beijing have better research ability than other areas in Chinese mainland.
【摘要】 目的 探讨抗氧化应激是否参与参附注射液预处理诱导的肾脏保护作用。 方法 健康成年雄性SD大鼠21只随机分为假手术对照组（Sham组）、肾脏缺血再灌注组（I/R组）和参附注射液组（SF组）；SF组给予参附注射液10 mL/kg腹腔注射，每日1次，连续给药7d。麻醉下行右肾切除后，用无损伤动脉夹钳夹左侧肾蒂60min，再灌注24 h，制备肾缺血再灌注损伤动物模型。比较各组SD大鼠再灌注24 h肾脏组织中超氧化物歧化酶（superonidedismutase，SOD）水平、过氧化氢酶（catalese，CAT）和丙二醛（malonicalaldehyed，MDA）含量。 结果 与Sham组相比，I/R和SF组肾脏组织SOD和CAT显著降低，而MDA明显升高（Plt;0.05）；与I/R组比，参附注射液能明显增加SOD和CAT水平（Plt;0.05），降低MDA含量（Plt;0.05）。 结论 参附注射液预处理可增强缺血再灌注损伤肾脏组织抗氧化应激，其表现为增强SOD和CAT的活力，减少MDA的生成。【Abstract】 Objective To explore the protective effect of Shenfu injection combined with antioxidant system on rats’ kidney after ischemia-reperfusion injury. Methods Twenty-one male Sprague Dawley (SD) rats were randomly divided into 3 groups: sham operation group (Sham group), ischemia-reperfusion group (IR group), and shenfu injection treated group (SF group). The rats were anesthetized with valebarbitone. Bilateral kidneys were exposed through midline incision. The right kidney underwent the nephrectomy and left renal pedicels were occluded for 60 minutes with a traumatic mini-clamp and then unclamped for 24 hours. Animals in SF group received Shenfu injection (10 mL/kg) through intraperitoneal injection every day for 7 days. About 24 hours after reperfusion, superoxide dismutase (SOD), CAT and malonical aldehyde (MDA) were measured. Results The levels of MDA were lower in SF group than those in IR group (Plt;0.05). The level of SOD and CAT in SF group increased more significantly than which did in IR group (Plt;0.05). Conclusion Our finding suggests that antioxidant system in SF group works more efficiently than IR group to overcome oxidative stress in renal ischemia-reperfusion injury.
