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:Preliminary clinical observations found that Jiawei Chunze Decoction is an effective formula for clinical treatment of urinary retention after spinal cord injury.Animal experiments have found that the phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt)signaling pathway is closely related to the degree of bladder dysfunction. OBJECTIVE:To further investigate the effects of Jiawei Chunze Decoction on bladder function and PI3K/Akt signaling pathway in rats with urinary retention. METHODS:Sixty female Sprague-Dawley rats were randomly divided into sham operation group,model group,Jiawei Chunze Decoction low-dose group,Jiawei Chunze Decoction high-dose group and agonist group.In the sham operation group,the spinal cord was exposed but not transected.In the other groups,the modified Hassan Shaker spinal cord transection method was used to prepare the model of sacral medullary injury.At 24 hours after modeling,the sham operation group and model group were intragastrically given equal volume of normal saline,Jiawei Chunze Decoction low-dose and high-dose groups were given Jiawei Chunze Decoction granules containing 14.4 and 28.8 g/kg,respectively,via intragastric administration for 4 weeks,and the agonist group was treated with an intraperitoneal injection of PI3K/Akt signaling pathway agonist 740Y-P at a dose of 0.02 mg/kg.After 4 weeks of treatment,the maximum bladder capacity,leakage point pressure and bladder compliance of rats in each group were detected by urine flow dynamics.The minimum bladder contraction tension and frequency of rats in each group were detected by detrusor pull test.The pathological changes of the rat bladder in each group were observed by hematoxylin-eosin staining.The concentrations of GRP78,CHOP and Caspase-12 in serum were detected by ELISA,and the mRNA and protein expressions of PI3K,Akt,GRP78,CHOP and Caspase-12 in bladder tissues were detected by RT-PCR and western blot,respectively. RESULTS AND CONCLUSION:Compared with the sham operation group,the maximum bladder volume,bladder compliance and minimum systolic tension of rats in the model group were increased(P<0.05),and the leakage point pressure and bladder contraction frequency were decreased(P<0.05);serum GRP78,CHOP,and Caspase-12 levels were also increased(P<0.05).The arrangement of bladder epithelial cells in the model group was disordered,and there was monocyte infiltration between cells,tissue edema,and detrusor tract atrophy.The mRNA and protein expressions of PI3K and Akt in bladder tissues were significantly decreased in the model group compared with the sham operation group,while those of GRP78,CHOP and Caspase-12 were increased(P<0.05).Compared with the model group,the maximum bladder volume,bladder compliance and minimum systolic tension of rats were decreased in the Jiawei Chunze Decoction low-dose,high-dose and agonist groups after 4 weeks of intervention(P<0.05),while the leakage point pressure and bladder contraction frequency were increased(P<0.05);serum GRP78,CHOP,Caspase-12 levels were decreased(P<0.05).The bladder epithelial cells in the three intervention groups were distributed evenly,arranged neatly,with less inflammatory cell infiltration and fuller detrusor muscle bundle.Compared with the model group,the mRNA and protein expressions of PI3K and Akt were increased in the three intervention groups,while those of GRP78,CHOP and Caspase-12 were decreased(P<0.05).The Jiawei Chunze Decoction high-dose group was better than the Jiawei Chunze Decoction low-dose group and shared the similar results with the agonist group.To conclude,Jiawei Chunze Decoction can improve the bladder function of rats with urinary retention after spinal cord injury,and the mechanism may be related to reducing the occurrence of endoplasmic reticulum stress in bladder tissue through the PI3K/Akt signaling pathway,and then alleviating apoptosis.

Multiple system atrophy (MSA) is a rare neurodegenerative disease with complex clinical manifestations, presenting substantial challenges in clinical diagnosis and treatment. Its symptoms and the eight extraordinary meridians are potentially correlated; therefore, this article explores the association between MSA symptom clusters and the eight extraordinary meridians based on their circulation and physiological functions, as well as their treatment strategies. The progression from deficiency to damage in the eight extraordinary meridians aligns with the core pathogenesis of MSA, which is characterized by "the continuous accumulation of impacts from the vital qi deficiency leading to eventual damage". Liver and kidney deficiency and the emptiness of the eight extraordinary meridians are required for the onset of MSA; the stagnation of qi deficiency and the gradual damage to the eight extraordinary meridians are the key stages in the prolonged progression of MSA. The disease often begins with the involvement of the yin and yang qiao mai, governor vessel, thoroughfare vessel, and conception vessel before progressing to multiple meridian involvements, ultimately affecting all eight extraordinary meridians simultaneously. The treatment approach emphasizes that "the direct method may be used for joining battle, but indirect method will be needed in order to secure victory" and focuses on "eliminate pathogenic factors and reinforce healthy qi". Distinguishing the extraordinary meridians and focusing on the primary symptoms are pivotal to improving efficacy. Clinical treatment is aimed at the target, and tailored treatment based on careful clinical observation ensures precision in targeting the disease using the eight extraordinary meridians as the framework and core symptoms as the specific focus. Additionally, combining acupuncture, daoyin therapy, and other method may help prolong survival. This article classifies clinical manifestations based on the theory of the eight extraordinary meridians and explores treatment.

OBJECTIVE:
To investigate the feasibility and effectiveness of the novel bone hook combined with finger-guided technique in the treatment of irreducible intertrochanteric femoral fractures in elderly.
METHODS:
Between January 2021 and August 2023, 23 elderly patients with irreducible intertrochanteric femoral fractures were treated with the novel bone hook combined with finger-guided technique. There were 10 males and 13 females; the age ranged from 68 to 93 years (mean, 76.2 years). The time from injury to operation ranged from 36 to 76 hours (mean, 51.2 hours). According to the classification standard proposed by TONG Dake et alin 2021, there were 10 cases of typeⅠA, 1 case of typeⅠB, 6 cases of type ⅡA, 4 cases of type ⅡB, and 2 cases of type ⅡC. The operation time, intraoperative blood loss, intraoperative fluoroscopy frequences, and quality of fracture reduction were recorded. The fracture healing time and occurrence of postoperative complications were observed during follow-up. At last follow-up, the Harris scoring system was used to evaluate the hip joint function.
RESULTS:
The operation time was 42-95 minutes (mean, 52.1 minutes). The intraoperative blood loss was 40-420 mL (mean, 126.5 mL). Intraoperative fluoroscopy was performed 14-34 times (mean, 20.7 times). According to the criteria proposed by Chang et al, the quality of fracture reduction was rated as good in 20 cases and acceptable in 3 cases. All patients were followed up 6-20 months (mean, 10.2 months). X-ray film showed that all fractures healed with the healing time of 3.0-5.5 months (mean, 4.0 months). At last follow-up, the Harris score of the hip joint ranged from 82 to 97 points (mean, 90.4 points). Among them, 14 cases were rated as excellent and 9 cases as good. No complication such as coxa vara, cutting of the cephalomedullary nail, nail withdrawal, or nail breakage occurred during follow-up.
CONCLUSION
The treatment of elderly patients with irreducible intertrochanteric femoral fractures by using the novel bone hook combined with finger-guided technique can achieve high-quality fracture reduction and fixation, and has a good effectiveness.

5.Correlation between depressive symptom and traditional Chinese medicine constitution among school aged children and adolescents
Chinese Journal of School Health 2025;46(9):1222-1225
Objective:
To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom.
Methods:
From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted.
Results:
The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05).
Conclusions
Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

OBJECTIVE To study the effects of peripheral blood-derived exosomes (Exo) intervened by Naozhenning (NZN) on injury of neuron cells HT22 induced by microglia BV-2 cells. METHODS Wistar rats were selected to prepare peripheral blood- derived Exo intervened by NZN (66.83 g/kg), referred to as NZN-Exo; peripheral blood-derived Exo intervened by normal saline and piracetam (PLXT, 1.62 g/kg) were prepared using the same method, denoted as KB-Exo and PLXT-Exo respectively, and all Exo were subsequently identified. Meanwhile, BV-2 cells were stimulated with 1 μg/mL lipopolysaccharide (LPS) to prepare LPS- stimulated supernatant, and non-LPS-stimulated supernatant was prepared following the same protocol. HT22 cells were divided into four groups: KB-Exo group (treated with non-LPS-stimulated supernatant+KB-Exo), model group (treated with LPS-stimulated supernatant+KB-Exo), PLXT-Exo group (treated with LPS-stimulated supernatant+PLXT-Exo), and NZN-Exo group (treated with LPS-stimulated supernatant+NZN-Exo), with the concentration of the corresponding Exo in all groups being 50 μg/mL. After 24 hours of culture, the proliferation of HT22 cells was detected by the CCK-8 assay and EdU assay; the apoptosis of HT22 cells was detected; the microstructure of HT22 cells was observed; the contents of interleukin-1β (IL-1β), IL-10, nuclear factor-κB (NF- κB), and tumor necrosis factor-α (TNF-α) in HT22 cells were measured, as well as the expression levels of TNF-α, NOD-like receptor thermal protein domain associated protein 3 (NLRP3), Caspase-1, B-cell lymphoma-2( Bcl-2), and Bcl-2-associated X protein (Bax). RESULTS KB-Exo, PLXT-Exo and NZN-Exo were successfully prepared, and all Exo exhibited typical cup-shaped contours and membrane-enclosed characteristics. Compared with KB-Exo group, model group showed significantly decreased cell proliferation rates (detected by CCK-8 and EdU), intracellular IL-10 levels, and Bcl-2 protein expression levels (P<0.05); while the cell apoptosis rate, intracellular levels of IL-1β, TNF-α, and NF-κB, as well as the expression levels of NLRP3, TNF-α, Caspase-1, and Bax proteins were significantly increased (P<0.05). Additionally, in the model group, the cells showed volume swelling, incomplete cell membrane, nucleolar rupture, significant swelling and deformation of mitochondria, and severe vacuolization. Compared with model group, the above quantitative indicators in the PLXT-Exo group and NZN-Exo group were significantly reversed (P<0.05), with large and round cell nuclei, intact nuclear membranes, and reduced mitochondrial vacuolization. CONCLUSIONS Peripheral blood-derived Exo intervened by naozhenning can alleviate the injury of neuronal cells HT22 by inhibiting inflammatory responses and cell apoptosis.

Objective :
To investigate the effects of resveratrol(Res) on fibroblast-like synoviocytes(FLS) in patients with rheumatoid arthritis(RA), and to explore the possible mechanism of Res inhibiting the release of inflammatory factors from FLS.
Methods :
FLS from RA patients were culturedin vitroand treated with different concentrations of Res(0, 20, 40, 80, 160, 320 μmol/L). The viability of FLS cells was detected by CCK-8 assay after 12 and 24 h. The contents of inflammatory factor interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) in cell supernatant were detected by ELISA. The expression levels of cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS) and stimulator of interferon gene(STING) were measured by Western blot; After lentivirus infection with FLS caused the cells to overexpress cGAS, the cells were divided into Control group(blank control), cGAS group(cGAS overexpression), Res+cGAS group(Res 160 μmol/L+cGAS overexpression) and Res group(Res 160 μmol/L). The expression level of STING protein in cells of each group was determined by Western blot, the viability of FLS cells in each group was detected by CCK-8, and the contents of inflammatory factor IL-6 and TNF-α in the supernatant of cells of each group were detected by ELISA method.
Results :
The results of CCK-8 experiment showed that under 40, 80, 160 μmol/L Res treatment, FLS viability decreased significantly after 24 h compared with blank control group(P<0.01). ELISA results showed that the contents of IL-6 and TNF-α in cell supernatant were also significantly decreased after treatment with Res of 40, 80 and 160 μmol/L(P<0.01). Meanwhile, Western blot results showed that Res could significantly decrease the protein expression levels of STING and cGAS in FLS cells after treatment of 40, 80 and 160 μmol/L(P<0.05,P<0.01). Compared with the Control group, the expression level of STING protein in FLS increased after overexpression of cGAS(P<0.05); compared with the Res group, the content of inflammatory factors in the supernatant of FLS and the expression level of STING protein in FLS significantly increased after overexpression of cGAS(P<0.01,P<0.05).
Conclusion
The appropriate concentration of Res can inhibit the release of inflammatory cytokines in FLS cells, which may be related to the blocking of cGAS-STING signaling pathway.

The escalating phenomenon of global population aging is posing multi-dimensional challenges to society, the economy and medical healthcare system.Among the significant health threats to the elderly population are cardiovascular diseases(CVD)and cognitive frailty(CF), both of which profoundly affect the quality of life and increase the risks of adverse health outcomes, including disability, hospitalization, and death.The concurrent presence of CVD and CF in elderly patients is prevalent, as these conditions share many common risk factors and underlying pathophysiological mechanisms, such as atherosclerosis, microcirculation dysfunction, and inflammation, which interact to perpetuate a vicious cycle.Notably, CF exhibits a certain degree of reversibility; thus, the implementation of a diagnosis and treatment paradigm that incorporates "comprehensive geriatric assessment and geriatric interdisciplinary teams" should be established as a conventional management strategy for elderly patients affected by both CVD and CF.Cognitive digital therapeutics, along with personalized exercise prescriptions based on cardiopulmonary exercise tests, may represent more appropriate precision interventions for these patients.Consequently, there is a necessity for further in-depth research in this area moving forward.

Objective:To analyze the distribution of allergen components of dust mite in children with airway allergic diseases.Methods:This was a cross-sectional study. The clinical data of children with dust mite-induced allergic asthma (AA) complicated with allergic rhinitis (AR) or allergic rhinitis who were treated in Department of Allergy,Beijing Children′s Hospital from January 2019 to October 2022 were retrospectively analyzed. The spedific IgE (sIgE) levels to Der p1,Der p2,Der p5,Der p7,Der p10,Der p21,Der p23 and Der f1,Der f2 were detected by protein chip method. The distribution of dust mite sensitized components and the sIgE levels in children with different airway allergic diseases and different ages were compared.Results:Among 138 children with airway allergic diseases,there were 97 boys and 41 girls,age (6.86±2.61) years old,and there were 106 cases of AA combined AR (AAAR group) and 32 cases of AR alone (AR group). The sensitization rates of Der p2 was the highest (75.4%,104/138),followed by Der f2 (74.6%,103/138),Der f1 (73.9%,102/138),Der p1 (71.7%,99/138),Der p21 (19.6%,27/138),Der p5 (16.7%,23/138),Der p23 (14.5%,20/138),Der p7 (11.6%,16/138) and Der p10 (2.9%,4/138). The co-sensitization rate of Der p1,Der p2,Der f1 and Der f2 was the highest (31.2%,43/138). There was no significant difference in sensitization rate of dust mites components between AAAR group and AR group(all P>0.05). AAAR group had higher levels of sIgE to Der p23 than AR group [0.1 (0,0.1) IU/ml vs. 0 (0,0.1) IU/ml,Z=-2.819, P=0.005]. There were no significant differences in the positive rate of dust mite components and sIgE levels between children aged≤6 and>6 years old with airway allergic diseases(all P>0.05). Conclusions:Der p1,Der p2,Der f1 and Der f2 are the major components of dust mites sensitizing airway allergic diseases in children. Der p1,Der p2,Der f1 and Der f2 are the main co-sensitizing components in children with dust mite-induced airway allergic diseases. Compared with AR,the sIgE level to Der p23 in children with AAAR is higher.

Objective:To study the effects of obesity on alveolar bone loss and gut microbiota in mice with periodontitis.Methods:Twenty-four seven-week-old female C57BL/6J mice were randomly divided into four groups based on table of random numbers ( n=6 in each group): normal-fat diet group (NFD group), high-fat diet group (HFD group), normal-fat diet and periodontitis group (NFD_PD group) and high-fat diet and periodontitis group (HFD_PD group). NFD and HFD groups were fed with normal or high-fat diet for twelve weeks respectively; NFD_PD and HFD_PD groups were induced to periodontitis by ligating the bilateral maxillary second molars with 5-0 silk thread at the fourth week after feeding with normal or high-fat diet respectively. The body weight was measured weekly. The mice were euthanized for collecting the samples at the end of the 12th week. Liver, kidneys, perirenal and retroperitoneal fat were weighed. Serum was collected to detect the level of serum lipids and inflammatory factors. The right maxilla bones were scanned by micro-CT. HE staining was performed to observe the periodontal tissue. The cecum contents were collected for gut microbiota 16S rRNA gene sequencing. Spearman correlation analysis was performed to analyze the correlation between the abundance of gut microbiota and serum inflammatory level and CT value. Results:After 12 weeks of high-fat diet fed, the body weight of HFD group [(26.52±1.96) g] was significantly higher than that of NFD group [(20.95±0.63) g] ( t=6.63, P<0.001). The body weight of HFD_PD group [(23.82±1.12) g] was significantly higher than that of NFD_PD group [(20.73±0.47) g] ( t=6.23, P=0.001). The serum levels of total cholesterol, triglyceride and low density lipoprotein in HFD group and HFD_PD group were significantly higher than those in NFD group and NFD_PD group ( P<0.01). The distance from the cemento-enamel junction to the alveolar bone crest (CEJ-ABC) on the mesial site of maxillary second molar in HFD_PD group [(647.46±47.46) μm] was significantly higher than that in NFD_PD group [(440.48±68.08) μm] ( t=5.58, P<0.001). HE staining showed that the maxillary second molar attachment loss, collagen fiber destruction and inflammatory cell infiltration were more significant serious in HFD_PD group compared with NFD_PD group. The levels of interleukin (IL)-1β, IL-6 and monocyte chemotactic protein-1 (MCP-1) of serum in HFD_PD group [(17.11±1.92), (31.61±3.20) and (204.42±35.96) ng/L, respectively] were significantly higher than those in NFD_PD group [(10.44±1.65), (19.96±2.09) and (147.36±10.76) ng/L, respectively] ( P<0.001, P<0.001, P=0.004). The 16S rRNA gene analysis revealed that the Bacteroides/Firmicutes ratio in HFD_PD group (4.00±3.30) was significantly higher than that in NFD_PD group (0.62±0.19) ( t=2.50, P=0.030). The abundance of Oscillospira in HFD_PD group [(12.25±0.05) %] was significantly higher than that in NFD_PD group [(2.80±0.01) %] ( t=4.64, P<0.001). The abundance of Parabacteroides in HFD_PD group [(0.25±0.27)% ] was significantly lower than that in NFD_PD group [(2.04±0.02)%] ( t=2.32, P=0.043). The β-diversity analysis of gut microbiota based on Bray-Curtis distance showed that samples of HFD_PD group and NFD_PD group were obviously grouped. Correlation analysis showed that the abundance of Oscillospira was positively correlated with IL-1β, IL-6, MCP-1 concentration and CEJ-ABC value in serum significantly ( r values were 0.80, 0.79, 0.80, 0.89, P<0.05). The abundance of Parabacteroides was negatively correlated with IL-1β, IL-6 concentration and CEJ-ABC value in serum significantly ( r values were -0.71, -0.71, -0.86, -0.95, P<0.05). Conclusions:Obesity promotes alveolar bone resorption in periodontitis mice and changes the gut microbiota. Oscillospira and Parabacteroides may play a key role.
