ABSTRACT
Objective:To explore the application effect of online and offline mixed teaching based on DingTalk platform in clinical practice teaching of respiratory department.Methods:The Batch 2016 ( n= 40) and Batch 2017 ( n=47) undergraduates of clinical medicine in Qiqihar Medical College were selected as the research objects, and they were divided into a control group and a research group. The control group adopted traditional offline theoretical teaching, while the research group adopted online-offline mixed teaching, focusing on teaching design and teaching objectives, teaching subjects, teaching resources, network platforms and teaching activities (classroom learning and evaluation). The theoretical and practical test scores of the two groups of interns were compared, and the evaluations of the students in the research group on the effect of online and offline mixed teaching were collected. Excel 2013 was used to sort out the data, and R software was used for data processing and statistical analysis. T-test was used for measurement data and Chi-square test was used for counting data. Results:The operational test scores [(28.16±1.70) points] and theoretical scores [(82.07±6.40) points] of the students in the study group were higher than those in the control group [(23.35±2.88) points and (76.20±5.67) points], with significant differences ( P<0.001). Compared with the students in the control group, the students in the research group were more satisfied with the mixed teaching method. Conclusion:The online and offline mixed teaching is conducive to improving students' comprehensive performance, learning effect, and promoting students' clinical diagnosis and treatment skills, self-study, innovation abilities and clinical competence.
ABSTRACT
Objective To investigate the effect of fine management in disinfection and sterilization of surgical instruments in Disinfection Supply Center. Method The surgical instrument sterilization and disinfection pass rate differences and operating room personnel satisfaction were investigated. Result The pass rate of disinfection and sterilization in surgical instruments of observation group was 100.0%, the surgeon satisfaction in using surgical instruments was 99.7%. Conclusion Application of fine management in sterilization of surgical instruments in disinfection supply center can improve the passing rate of the sterilization, improve the satisfaction of the surgical staff, and also to ensure the quality of the surgical instrument in sterilization, reduce the risk of infection in patients, protect patient safety, which is worth further clinical application.
ABSTRACT
Objective To investigate the changes of saliva biochemical parameters in the dynamic evolution of “normal constitution - kidney deficiency constitution - kidney deficiency syndrome”.Methods Totally 24 male and female SD rats of 3 months old (12 male rats and 12 female rats) were put in packet pair cage. Pregnant rats were randomly divided intoⅠ andⅡ groups, 6 rats in each group.Ⅰ group was without intimidation during pregnancy, with normal feeding, and then after the birth, 20 rats were randomly selected as normal control group and kidney deficiency syndrome model group, 10 rats in each group, half male and half female.Ⅱ group, from gestation day 2, was given intimidation until postnatal. 10 half male and half female rats were randomly selected as model group of kidney deficiency constitution. Rats in each group received normal feeding conditions for 6 weeks. The kidney deficiency syndrome model group was given intramuscular injection of hydrocortisone 25 mg/kg body weight every day, while normal control group and kidney deficiency constitution model group were injected with the same amount of normal saline for 10 consecutive days. The changes of salivary biochemical parameters were observed in each group of rats.Results Compared with the normal control group, salivary pH in the kidney deficiency constitution group and kidney deficiency syndrome group significantly increased (P<0.01). CK, ALT, AST, ALP levels in the kidney deficiency constitution group were reduced, but the contents of K, P, TP, AMY increased. The levels of CK, ALT, AST, ALP and LDH in the kidney deficiency syndrome decreased, while the contents of K, P, TP, and AMY increased (P<0.05,P<0.01). Compared with the kidney deficiency constitution group, the content of LDH in the kidney deficiency syndrome group decreased (P<0.05).Conclusion Rat saliva composition changes did occur in the kidney deficiency constitution group and kidney deficiency syndrome group.
