Objective To understand the current cognition status of stroke rehabilitation nursing knowledge in young nurses of the department of neurology.Methods Self-designed questionnaires were used for investigating 273 young nurses between 20 and 30 years old of the department of neurology of 4 tertiary hospitals in Zhengzhou.Results The current status of stroke rehabilitation nursing knowledge of the nurses surveyed was generally at a low level.There were no significant differences among nurses with different education degrees,professional titles and whether their relatives suffered from stroke.However,there were significant differences among nurses with different professional lives and whether the department carried out rehabilitation care.Conclusions Nursing educators and managers need to find a new way to improve the level of stroke rehabilitation nursing knowledge of the young nurses.

Objective:To explore the effect of WeChat mini program in immunotherapy management of pediatric patients with combined allergic rhinitis and asthma syndrome (CARAS).Methods:Using the convenient sampling method, 101 children with CARAS who received sublingual immunotherapy in the First Affiliated Hospital of Zhengzhou University from January 2019 to January 2020 were selected as the research objects. The standardized management team of immunotherapy clinic was established. The newly developed specific immunotherapy Wechat applet was used to establish a new model of nurse-patient interaction and communication. The disease knowledge was regularly pushed, medication reminder, nurse telephone intervention and other standardized management were delivered through the Wechat applet to implement continuous nursing for children. The effects of this management model on medication compliance, rhinitis symptoms and asthma control were analyzed.Results:A total of 101 children were included in this study, 3 cases were lost to follow-up, and a total of 98 cases completed the study. After 12 months of intervention, the drug possession score of dust mite drops increased from (83.43±3.68) to (91.78±3.71), the symptom score of allergic rhinitis decreased from (5.83±1.32) to (1.94±0.98), and the score of asthma test questionnaire increased from (18.12±3.99) to (24.97±3.09), the proportion of children with complete control of asthma increased from 48.0% to 90.8%, and the proportion of children without control of asthma decreased from 10.2% to 1.0% (all P<0.05). Conclusion:The immunotherapy management of pediatric patients with combined allergic rhinitis and asthma syndrome based on WeChat mini program can effectively improve the compliance of children and their family, improve the control level of allergic rhinitis and asthma.

ObjectiveTo compare the feasibility of establishing the rat model of acute coronary syndrome with combined blood stasis and poison by lipopolysacharide （LPS） injection， ligation of coronary artery and different combinations of the two methods. MethodA total of 225 male SD rats were randomly divided into sham operation group， simple coronary artery ligation group， first injected LPS group ［LPS（5 mg·kg）injection 24 h before coronary artery ligation］ and follow injected LPS group ［LPS（5 mg·kg）injection 10 min after coronary artery ligation］. The indexes of each group were detected at 3， 24， 72 h after modeling， and the model was comprehensively evaluated. The general state and macroscopic evaluation indexes of traditional Chinese medicine （TCM） syndrome （tongue and pulse） of rats in each group were observed. ECG and echocardiography were used to evaluate cardiac function， and the myocardial ischemia and infarction areas were measured by Evans blue/2，3，5-triphenyltetrazolium chloride （TTC） staining. The content of creatine kinase isoenzyme （CK-MB）， lactate dehydrogenase （LDH）， creatine kinase （CK）， and troponin T （cTnT） in serum as well as interleukin-1 β （IL-1β） and IL-6 changes were determined by biochemical method or enzyme-linked immunosorbent assay （ELISA）. Hematology analyzer was adopted to determine the white blood cell （WBC） count， and the four coagulation indexes， platelet aggregation rate， hemorheology and other coagulation evaluation indexes were also detected. The myocardial tissue was observed by hematoxylin-eosin（HE）staining. ResultAfter 3 h of modeling， compared with the conditions in sham operation group， the R， G and B values of tongue of rats （P<0.01）， pulse amplitude （P<0.01）， and cardiac function in simple coronary artery ligation group were decreased， and the color of hypoglossal veins became purple（P<0.01）. The content of CK， LDH， cTnT， IL-1β and IL-6 in serum（P<0.05）， myocardial infarction area（P<0.01）， and total number of WBCs （P<0.05）were increased. Compared with simple coronary artery ligation group， first injected LPS group and follow injected LPS group had increased hypoglossal veins， decreased R value of tongue and elevated cTnT content （P<0.01）， while follow injected LPS group had reduced B value of tongue， decreased cardiac output （CO）（P<0.05）， increased IL-1β content， and thinned left ventricular anterior walls at end-systole （LVAWs）（P<0.01）. After 24 h of modeling， compared with sham operation group， simple coronary artery ligation group presented significantly decreased R， G and B values of tongue， lengthened purplish dark hypoglossal veins （P<0.01）， reduced pulse amplitude（P<0.01） and cardiac function， enlarged myocardial infarction area（P<0.01）， increased whole blood viscosity， platelet aggregation rate， fibrinogen （FIB）， shortened prothrombin time （PT） and thrombin time （TT）（P<0.01）， and elevated total number of WBCs （P<0.01）and content of CK， LDH， cTnT and IL-6 in serum（P<0.05）. Compared with the conditions in simple coronary artery ligation group， the pulse amplitude， R， G and B values of tongue （P<0.01）， and ejection fraction （EF） and fractional shortening （FS） scores （P<0.05）dropped， and hypoglossal veins were deepened and lengthened（P<0.05）， and cTnT content was increased（P<0.01）in first injected LPS group and follow injected LPS group. However， follow injected LPS group had thinned LVPWs， increased LDH content， platelet aggregation rate（P<0.05）， myocardial infarction area， and total number of WBC， level of IL-1β（P<0.05）， and shortened TT（P<0.01）. Additionally， 72 h after modeling， compared with sham operation group， simple coronary artery ligation group showed significantly reduced pulse amplitude， lowered R， G and B values of tongue， thickened and lengthened hypoglossal veins（P<0.01）， decreased cardiac function， and increased content of cTnT， FIB， whole blood viscosity（P<0.01），platelet aggregation rate， level of IL-6 and IL-1β（P<0.05）. Compared with the conditions in simple coronary artery ligation group， the hypoglossal veins of the first injected LPS group and the follow injected LPS group were more purple， and the content of cTnT was boosted（P<0.01）， whereas follow injected LPS group had decreased pulse amplitude， R， G and B values of tongue， EF and FS scores （P<0.05）， and enlarged myocardial infarction area（P<0.01）. ConclusionCompared with the other modeling methods and models at different modeling time， the established model by LPS injection 10 min after coronary artery ligation for 24 h was more consistent with the clinical characteristics of acute coronary syndrome with combined blood stasis and poison.

ObjectiveTo explore whether the mechanism of Shuangshen Ningxin capsules （SSNX） in alleviating myocardial ischemia-reperfusion injury （MIRI） in rats is related to the regulation of mitochondrial fission and fusion. MethodThis study focused on Sprague Dawley （SD） rats and ligated the left anterior descending branch of the coronary artery to construct a rat model of MIRI. The rats were divided into the sham operation group， model group， SSNX group （90 mg·kg^-1） and trimetazidine group （5.4 mg·kg^-1）. The activity of superoxide dismutase （SOD） and the content of malondialdehyde （MDA） were detected by micro method. Changes in mitochondrial membrane potential （△Ψm） and the degree of mitochondrial permeability transition pore （mPTP） opening were detected by the chemical fluorescence method. The intracellular adenosine triphosphate （ATP） level was detected by the luciferase assay. The messenger ribonucleic acid （mRNA） and protein expression levels of mitochondrial fission and fusion related factors dynamin-related protein 1 （DRP1）， mitochondrial fission 1 protein （FIS1）， optic atrophy protein 1 （OPA1）， mitochondrial outer membrane fusion protein 1 （MFN1）， and MFN2 were detected by real-time polymerase chain reaction （real-time PCR） and Western blot. ResultCompared with the sham operation group， the model group showed a decrease in serum SOD activity and an increase in MDA content. The opening level of mPTP， the level of △Ψm and ATP content decreased， the protein expressions of mitochondrial fission factors DRP1 and FIS1 increased， and the protein expressions and mRNA transcription levels of fusion related factors OPA1 and MFN1 decreased. Compared with the model group，SSNX significantly increased serum SOD activity， reduced MDA content， increased intracellular ATP level and △Ψm， reduced the opening level of mPTP， downregulated the protein expressions of mitochondrial fission factors DRP1 and FIS1， and increased the mRNA transcription levels and protein expressions of fusion related factors OPA1 and MFN1. ConclusionSSNX inhibits the expressions of mitochondrial fission factors DRP1 and FIS1， and increases the expressions of fusion related factors OPA1 and MFN1， inhibiting mitochondrial fission and increasing mitochondrial fusion， thereby alleviating MIRI.
