ABSTRACT
Objective:To study the effect of micro-course teaching combined with teacher standardized patient combined with objective structured clinical examination (TSP/OSCE) on clinical practice teaching of pediatric nursing.Methods:Forty nurses who performed clinical practice in Pediatrics Department from February 2019 to July 2019 were selected as the control group, and traditional teaching was adopted in the group. In addition, 42 nurses who performed clinical practice in Pediatrics Department from August 2019 to January 2020 were selected as the research group, and the micro-course teaching combined with TSP/OSCE mode teaching was adopted in the group. Two groups of nurses' theoretical and practical skills assessment results were analyzed, and a questionnaire survey was conducted to assess nurses' satisfaction with the teaching of pediatric nursing clinical practice training mode. SPSS 22.0 was used for t test and chi-square test. Results:The research group nurses' theoretical and practical skills assessment scores were better than those of the control group, and the difference was statistically significant ( P=0.000).The nurses in the research group were more satisfied than those in the control group with such eight aspects as improving practical skills, emergency response capabilities, humanistic care and service capabilities, communication skills, and stimulating their interest in nursing learning. There were statistically significant differences ( P<0.05). Conclusion:The use of micro-teaching combined with TSP/OSCE mode in the clinical practice teaching of pediatric nursing can improve nurses' clinical practice ability and increase nurses' satisfaction in pediatric training.
ABSTRACT
Objective To investigate the optimal initial concentration of microRNA22 agomir in epilepsy model induced by lithium chloride-pilocarpine after single injection of lateral ventricle.Methods 36 rats with acute temporal lobe epilepsy were randomly divided into 6 groups:the control group and the other five groups were the experimental group.All epilepsy rats were selected for right lateral ventricle injection.The control group was given negative control reagent,while the experimental group were given 0.1 mmol/L,2.5 mmol/L,5 mmol/L,10 mmol/L,20 mmol/L different concentrations of miRNA22agomir reagent.6 rats in each group were randomly selected for acute phase experiment after 3 days of administration.The expression of P2X7 in hippocampus of epilepsy rats was determined by Western blot and quantitative real-time polymerase chain reaction (qRT-PCR).Results Compared with control group,the protein and mRNA expression of P2X7 reduced in all of the model group.The protein and mRNA expression level of P2X7 protein in hippocampus of rats injected with 2.5 mmol/L,5 mmol/L and 10 mmol/L in each experimental group were significantly lower than that in the other two groups (P ＜ 0.05).Moreover,the protein and mRNA expression level of P2X7 were the lowest at 2.5 mmol/L injection and 10 mmol/L,and there was no significant difference between the two groups (P ＞ 0.05).Conclusions The optimal onset concentration for unilateral lateral ventricle injection miRNA22 agomir treatment of temporal lobe epilepsy is 2.5 mmol/L.
