ABSTRACT
Objective:To investigate the status quo of multi-level pre-job training for clinical nursing teachers and analyze their training needs, so as to provide reference for the design of pre-job training for clinical nursing teachers.Methods:A cross-sectional survey method was used to investigate 172 clinical nursing teachers in a tertiary general hospital in Harbin from April 2020 to June 2020 with multi-level pre-job training mode. The status quo of pre-job training and the training needs of teachers were analyzed. SPSS 17.0 was used to process the original data statistically.Results:Among the 172 respondents, 138 teachers (80.2%) were under 35 years old, and 133 teachers (77.3%) had a bachelor's degree or less; 89 teachers (51.7%) confirmed that hospitals or departments would carry out pre-job training in a planned and organized way, 10 teachers (5.8%) said that hospitals or departments had never organized training, 41 teachers (23.8%) had never participated in pre-job training, and 80 teachers (46.5%) had participated in pre-job training 1-3 times. There were 5 duplicates in the first 8 training contents of in-hospital training and in-department training, including knowledge of common diseases, nursing procedures, communication skills, hospital rules and regulations, and teaching methods. The total score of training demand was (154.51± 40.35) points, and the overall demand rate was 81.3%, which was at the high level. The dimensions with the highest scoring rate were legal system and humanistic literacy, with a scoring rate of 83.0%. The dimension with the lowest score was teaching management, with a score of 74.9%. The scoring rate of training needs with the highest points won nine items respectively on students' basic quality (self-supervision, willingness to learn, professional quality, etc.) (84.7%), training of legal knowledge (84.4%), incompatibility of drugs commonly used in department (84.3%), nurse etiquette (83.3%), nursing risk prevention (83.1%), evaluation methods of student education (83.1%), nurse-patient communication skills (83.0%), nurses and patients medication observation points of commonly used drugs in the department (83.0%), and effects of commonly used drugs in department (82.9%). Among the top three training forms, 84 students (48.8%) received online learning, 74 students (43.0%) received lectures from experienced teachers in hospitals, and 72 students (41.9%) received experience exchange and sharing seminars.Conclusion:The talent structure of clinical nursing teachers in this hospital is relatively young, and the first education level is low. Therefore, the pre-job training of clinical nursing teachers should be strengthened vigorously. The awareness rate and participation rate of pre-job training are average, so we should strengthen the release of training information from various channels, improve the awareness rate of training activities, clarify the encouragement or reward measures to participate in pre-job training activities, and improve the participation rate of training activities. Pre-job training content is repeated at every level, with a gap between the training needs of teachers in clinical nursing teaching. It's suggested that the teaching hospitals combine with their training objects of training needs, take the online-offline mixed mode of training, reasonably plan training contents as a whole at all levels, avoid training content repetition and waste of teachers, and organize teachers to timely exchange and share experiences.

Except the normal group, a longitudinal incision, about 1.5 cm in length was done along the neck midline in the rats of the rest groups to prepare the model of thyroid incisional pain. In the Futu (LI 18) group, the Hegu (LI 4)-Neiguan (PC 6) group and the Zusanli (ST 36)-Yanglingquan (GB 34) group, after modeling for 4 h, 24 h and 48 h, EA was applied to bilateral "Futu" (LI 18), "Hegu" (LI 4) "Neiguan" (PC 6) and"Zusanli" (ST 36) "Yanglingquan" (GB 34) separately, once a day, continuously for 3 days. In the normal group and the model group, no any intervention was applied. The thermal radiant apparatus was used to detect the thermal pain threshold (PT). The fluorescence quantitative RT-PCR and the Western blotting (WB) were used to determine the expressions of protein and gene of microglia activation markers Iba1 and CD11b and the astrocyte specific protein marker, glial fibrillary acid protein (GFAP) in cervical spinal cord (Cto C) after intervention in the rats of each group.</p><p><b>RESULTS</b>After intervention, as compared with the normal group, in the model group, the neck PT was reduced apparently (<0.05), the expressions of Iba1 and CD11b and GFAP mRNA as well as the protein expressions in the spinal cord of Cto Cwere up-regulated apparently (<0.05,<0.01). As compared with the model group, in the Futu (LI 18) and the Hegu (LI 4)-Neiguan (PC 6) group, PT was increased significantly (both<0.05) and that did not change apparently in the Zusanli (ST 36)-Yanglingquan (GB 34) group (>0.05). In the Futu (LI 18) group, the protein and gene expressions of Iba1, CD11b and GFAP were lower than those in the model group (all<0.05). In the Hegu (LI 4)-Neiguan (PC 6) group, the expressions of Iba1 mRNA, CD11b protein, GFAP mRNA and protein were all lower apparently than those in the model group (all<0.05). In the Zusanli (ST 36)-Yanglingquan (GB 34) group, the expressions of Iba1, CD11b and GFAP proteins were not different significantly as compared with the model group (all>0.05). In the Zusanli (ST 36)-Yanglingquan (GB 34) group, the expressions of Iba1 mRNA and CD11b mRNA and protein expressions in the spinal cord of Cto Cwere higher apparently than those in the Futu (LI 18) group (<0.01,<0.05); the expressions of Iba1 mRNA and CD11b protein expressions were higher than those in the Hegu (LI 4)-Neiguan (PC 6) group (all<0.05); GFAP mRNA and protein expressions were higher apparently than those in the Futu (LI 18) group and the Hegu (LI 4)-Neiguan (PC 6) group (all<0.05).</p><p><b>CONCLUSIONS</b>EA at "Futu" (LI 18) or "Hegu" (LI 4), "Neiguan" (PC 6) relieves the acute neck incisional pain in the rats and its effect may be closely relevant with the down-regulation of the activities of microgliacytes and astrocytes in the spinal cords.</p>
ABSTRACT
[ ABSTRACT] AIM: To study the protective effect of ischemia preconditioning ( IPC ) on ischemia/reperfusion ( IR)-damaged myocardium in young and old rats .METHODS: Male Wistar rats aged at 3 months ( young ) and 20 months ( old) were used to establish myocardial IPC model and IR model with the method of Langendorff heart perfusion . The rats were divided into young ischemia/reperfusion ( YIR) group, young ischemic preconditioning ( YPC) group, old ischemia/reperfusion ( OIR) group and old ischemic preconditioning ( OPC) group.Transmission electron microscopy was used to observe the ultrastructural changes of myocardial tissue and myocardial mitochondria .The myocardial infarction area was determined by TTC staining .The lactate dehydrogenase ( LDH) content in coronary effluent fluid and the levels of su-peroxide dismutase ( SOD) and malondialdehyde ( MDA) in myocardial tissues were detected by the method of colorimetry . The levels of nitrated and carbonylated proteins in myocardial tissue were measured by ELISA .The myocardial cell apopto-sis was analyzed by TUNEL assay .The mitochondrial respiratory function and mitochondrial permeability transition pore o-pening induced by calcium load were evaluated by oxygen electrode method .RESULTS: Compared with YIR group , the myocardial infarction area in YPC group was obviously smaller , SOD activity in myocardial tissues increased , LDH activity in coronary effluent fluid and the content of MDA decreased , and the levels of nitrated and carbonylated proteins in the car-diac tissues reduced .In YPC group, the mitochondrial membrane structure appeared intact , cristae of the mitochondria showed close arrangement , and the matrix was compressed under the electron microscope .Myocardial mitochondrial respir-atory control rate , state Ⅲoxygen consumption and the P/O ratio in YIR group all significantly increased , proton leak de-creased, mitochondrial swelling induced by calcium distinctly reduced , and myocardial apoptosis rate declined .No signifi-cant difference of the above indexes between OIR group and OPC group was observed .Compared with YPC group , myocar-dial ultrastructural damage increased clearly , cardiac oxidative stress increased , mitochondrial respiratory function de-clined, and cell apoptosis and necrosis increased in OPC group .CONCLUSION:Ischemic preconditioning has protective effect against myocardial IR injury in young rat hearts , while old rat hearts were less sensitive to ischemic preconditioning , leading to bluntness of cardioprotection with IPC in aging hearts .This may be related to mitochondrial injury and severe cel-lular apoptosis caused by increase of cardiac oxidative stress levels in the aging ischemic preconditioning heart .

ABSTRACT
Drug delivery system in tumor targeting research has always been a difficult problem.Apoptosis in vitro experiments and body pharmacokinetic experiments can not reflect the targeting of drug delivery system indirectly.Imaging techniques both in vivo and in vitro solve the problem,researchers can not only observe the drug delivery system in the target organ,the target tissue and target cell directly,but also analyze quantitatively and qualitatively.
