ObjectiveTo systematically evaluate the application of narrative education in undergraduate nursing teaching， to understand the current application status of narrative education， and to provide a theoretical basis for the subsequent establishment of a sound narrative education system. MethodsA systematic search was conducted for studies published in Chinese and English databases on applying narrative education to undergraduate nursing teaching， with the search period ranging from database inception to February 23， 2025. Literature was screened， and relevant information was extracted. A rigorous quality evaluation was conducted on the included studies， and a descriptive analysis was performed on their content. ResultsA total of 20 papers were included， involving 3，180 research subjects， all of whom were undergraduate nursing students. The results of descriptive analysis showed that the teaching model of narrative education primarily encompassed reading narrative works， watching films and videos， performing narrative scenarios， and writing reflective journals. The course setting and content covered pre-teaching preparation and in-teaching implementation. The evaluation of teaching effectiveness included the evaluation of teachers’ teaching methods （student evaluation/self-evaluation） and the evaluation of students’ learning effectiveness （course grade evaluation/humanistic care scale/empathy scale assessment， and others）. ConclusionNarrative education combines abstract concepts with concrete clinical situations， which not only enriches students’ learning experiences but also enhances their humanistic literacy. Meanwhile， it provides teachers with opportunities to develop their narrative teaching skills， which requires them to possess profound professional knowledge and employ narrative techniques to guide students in reflection and critical thinking， thereby improving teaching quality and learning outcomes. Future efforts should consistently deepen the connotation research of narrative education and build a systematic nursing education system.

BACKGROUND:Degenerative scoliosis is defined as a condition that occurs in adulthood with a coronal cobb angle of the spine>10° accompanied by sagittal deformity and rotational subluxation,which often produces symptoms of spinal cord and nerve compression,such as lumbar pain,lower limb pain,numbness,weakness,and neurogenic claudication.The finite element method is a mechanical analysis technique for computer modelling,which can be used for spinal mechanics research by building digital models that can realistically restore the human spine model and design modifications. OBJECTIVE:To review the application of finite element method in the etiology and treatment of degenerative scoliosis. METHODS:The literature databases CNKI,PubMed,and Web of Science were searched for articles on the application of finite element method in degenerative scoliosis published before October 2023.Search terms were"finite element analysis,biomechanics,stress analysis,degenerative scoliosis,adult spinal deformity"in Chinese and English.Fifty-four papers were finally included. RESULTS AND CONCLUSION:(1)The biomechanical findings from the degenerative scoliosis model constructed using the finite element method were identical to those from the in vivo experimental studies,which proves that the finite element method has a high practical value in degenerative scoliosis.(2)The study of the etiology and treatment of degenerative scoliosis by the finite element method is conducive to the prevention of the occurrence of the scoliosis,slowing down the progress of the scoliosis,the development of a more appropriate treatment plan,the reduction of complications,and the promotion of the patients'surgical operation.(3)The finite element method has gradually evolved from a single bony structure to the inclusion of soft tissues such as muscle ligaments,and the small sample content is increasingly unable to meet the research needs.(4)The finite element method has much room for exploration in degenerative scoliosis.

The neurophysiological mechanisms by which exercise improves cognitive function have not been fully elucidated. A comprehensive and systematic review of current domestic and international neurophysiological evidence on exercise improving cognitive function was conducted from multiple perspectives. At the molecular level, exercise promotes nerve cell regeneration and synaptogenesis and maintains cellular development and homeostasis through the modulation of a variety of neurotrophic factors, receptor activity, neuropeptides, and monoamine neurotransmitters, and by decreasing the levels of inflammatory factors and other modulators of neuroplasticity. At the cellular level, exercise enhances neural activation and control and improves brain structure through nerve regeneration, synaptogenesis, improved glial cell function and angiogenesis. At the structural level of the brain, exercise promotes cognitive function by affecting white and gray matter volumes, neural activation and brain region connectivity, as well as increasing cerebral blood flow. This review elucidates how exercise improves the internal environment at the molecular level, promotes cell regeneration and functional differentiation, and enhances the brain structure and neural efficiency. It provides a comprehensive, multi-dimensional explanation of the neurophysiological mechanisms through which exercise promotes cognitive function.

ObjectiveTo observe the effects of Tongmai Kaiqiao pills on AMP-activated protein kinase （AMPK）/peroxisome proliferator-activated receptor gamma coactivator-1α （PGC-1α） signaling pathway and mitochondrial biogenesis in hippocampal tissue of rats with vascular cognitive impairment （VCI） and to investigate the potential mechanism of Tongmai Kaiqiao pills in improving cognitive impairment in rats with VCI. MethodsTwelve of 72 male SD rats were selected as the sham operation group， and the remaining rats were modelled using the modified 2VO method. The rats that were successfully modelled were divided into the model group， the high-dose group of Tongmai Kaiqiao pills （27.6 g·kg^-1）， the low-dose group of Tongmai Kaiqiao pills （13.8 g·kg^-1）， the combination group （27.6 g·kg^-1 Tongmai Kaiqiao pills + 25 mg·kg^-1 dorsomorphin）， and the donepezil hydrochloride group （0.45 g·kg^-1） according to the random number table method. After four weeks of continuous intraperitoneal injection of the corresponding drugs， the Morris water maze test was used to test the learning and memory ability of rats. Hematoxylin-eosin （HE） staining and Nissl staining were used to detect pathological changes in the hippocampus of the rats. The content of mitochondrial adenosine triphosphate （ATP） in the brain hippocampus was detected by colorimetry， and reactive oxygen species （ROS） level was detected in rat mitochondria by MitoSOX Red assay. Mitochondrial DNA copy number was detected by real-time fluorescent quantitative PCR （Real-time PCR）. Pathological changes in mitochondria were observed by transmission electron microscopy （TEM）， and AMPK， PGC-1α， phosphorylated AMP-activated protein kinase （p-AMPK）， nuclear respiratory factor 1 （Nrf1）， and mitochondrial transcription factor A （TFAM） protein expression in the hippocampus of the rats were detected by Western blot. ResultsCompared with those in the sham operation group， rats in the model group had a reduced number of platform crossings （P<0.01）， significantly prolonged evasion latency （P<0.01）， disorganized neuronal arrangement in the hippocampal region， widened gaps， and blurred nucleus membrane and nucleolus boundaries. The emergence of necrotic cells was visible. The color of the nissl bodies was light， and the number was reduced with severe loss. Mitochondria were atrophied， and cristae were lost. Severe damage was observed. The content of ROS was increased， and the level of ATP was decreased. mtDNA copy number decreased significantly （P<0.01）， and the protein expression of p-AMPK， PGC-1α， Nrf1， and TFAM decreased （P<0.05， P<0.01）. Compared with those in the model group， rats in the high-dose group of Tongmai Kaiqiao pills and donepezil hydrochloride group showed a shorter time to find the platform （P<0.01）， increased number of platform crossings （P<0.01）， restored mitochondrial morphology and structure of the hippocampal neurons， alleviated neuronal death， increased number of nissl bodies， weaken degree of injury， lower content of ROS， and significantly increased levels of ATP and number of copies of mtDNA （P<0.05， P<0.01）. In addition， there was increased protein expression of p-AMPK， PGC-1α， Nrf1， and TFAM （P<0.05， P<0.01）. Compared with the model group， the evasion latency was shortened in the low-dose group of Tongmai Kaiqiao pills （P<0.01）， and the number of platform crossings was increased， but the difference was not statistically significant. The mitochondria were swollen and deformed， and the cristae became shorter and partially disappeared. The degree of damage did not improve significantly， and the number of nissl bodies was increased but not statistically significant. The ROS content decreased （P<0.01）， but there was no significant difference in ATP level and mtDNA copy number. The protein expression of PGC-1α was increased （P<0.05）， but there was no significant difference in the protein expression of p-AMPK， Nrf1， and TFAM， and the results were not statistically significant. Compared with the donepezil hydrochloride group， there was no significant change in the results of each assay in the high-dose group of Tongmai Kaiqiao pills， and the difference was not statistically significant. Compared with the high-dose group of Tongmai Kaiqiao pills， rats in the combination group had a significantly lower number of platform crossings （P<0.01）， a significantly longer evasion latency （P<0.01）， a reduced number of neuronal cells， disorganized tissue structure， swollen and blurred cell outlines， a significant reduction in the number of nissl bodies. Moreover， there was an increase in the content of ROS， a decrease in the level of ATP and the number of mtDNA copies （P<0.01）， and a decrease in the expression of p-AMPK， PGC-1α， Nrf1， and TFAM （P<0.05）. ConclusionTongmai Kaiqiao pills is able to improve cognitive function in rats by activating the AMPK/PGC-1α signaling pathway， promoting mitochondrial biogenesis， and attenuating pathological damage to neurons in the hippocampal region， thereby demonstrating its therapeutic potential.

Sleeve gastrectomy is currently the most commonly performed bariatric surgery procedure. There remains controversy regarding the intraoperative management of hiatal hernia during sleeve gastrectomy for obesity patients. In China, the mainstream approach is active explora-tion and repair of the hiatal hernia during surgery. Nevertheless, some reports suggest that this may not lead to definitive outcomes and might even exacerbate gastroesophageal reflux symptoms. Based on clinical experience, the authors discuss the current strategies of intraoperative management of hiatal hernia during sleeve gastrectomy, and explore the clinical management strategies for obesity patients with esophageal hiatal hernia undergoing sleeve gastrectomy.

Peyronie's disease (PD) is a disorder characterized by fibrous plaque formation in the penile tissue that leads to curvature and complications in advanced stages. In this study, we aimed to compare four injectable induction agents for the establishment of a robust rat model of PD: transforming growth factor-β1 (TGF-β1), fibrin, sodium tetradecyl sulfate (STS) combined with TGF-β1, and polidocanol (POL) combined with TGF-β1. The results showed that injection of TGF-β1 or fibrin into the tunica albuginea induced pathological endpoints without causing penile curvature. The STS + TGF-β1 combination resulted in both histological and morphological alterations, but with a high incidence of localized necrosis that led to animal death. The POL + TGF-β1 combination produced pathological changes and curvature comparable to STS + TGF-β1 and led to fewer complications. In conclusion, fibrin, STS + TGF-β1, and POL + TGF-β1 all induced PD with a certain degree of penile curvature and histological fibrosis in rats. The POL + TGF-β1 combination offered comparatively greater safety and clinical relevance and may have the greatest potential for PD research using model rats.
