Objective To explore the barriers to postoperative self-management behaviors in patients with pituitary adenoma and provide a theoretical basis for developing nursing intervention strategies.Methods Using a purposive sampling method,16 postoperative pituitary adenoma patients admitted to a tertiary hospital in Zhengzhou from July 2024 to January 2025 were selected for semi-structured interviews.The interview data were analyzed and refined through Colaizzi's phenomenological analysis method.Results A total of 4 themes and 12 subthemes were extracted,including postoperative physiological dysfunction(sensory dysfunction,difficulty in managing diabetes insipidus,fatigue syndrome),psychosocial adaptation barriers(self-image distress,fear of disease recurrence,restricted information delivery),challenges in maintaining health behaviors(environment-behavior conflicts,insufficient adherence to medication and activity guidelines,inadequate complication management),deficiencies in support systems(non-specific postoperative guidance,poor communication channels,insufficient coordination of medical resources).Conclusion Postoperative self-management behaviors in pituitary adenoma patients are influenced by multidimensional factors,necessitating comprehensive intervention strategies addressing physiological,psychological,behavioral,and systemic support levels.

Objective To explore the role of postdoctoral talent cultivation in high-quality development of public hospi-tals.Methods The data of 165 postdoctoral fellows were analyzed from Zhongshan Ophthalmology Center,Sun Yat-sen Univer-sity over the past decade.The analysis involved examining the entire management process from recruitment to completion,inclu-ding the improvement of relevant systems,evaluation standards,implementation of hierarchical management,mentor-student in-teractions,and academic exchanges,as well as studying the quality enhancement of the postdoctoral talent pool,research output,and employment analysis.Results The standardized management of whole postdoctoral cultivation process and the continuous improvement of systems significantly enhanced the achievements of postdoctoral fellows in research,publications,and commer-cialization of the scientific and research findings.For instance,from 2018 to 2022,the number of National Science Foundation-funded programs that the postdoctoral fellows obtained accounted for 26.7％of the total number,while the number of provincial and ministerial funded programs accounted for 73.3％.In 2020,the proportion of postdoctoral researchers who obtained the Na-tional Natural Science Foundation of China's Youth Program was 80％of the total.In 2021,the proportion of postdoctoral fellows who published papers with an impact factor of above 10 as the first author or co-first author was 45.83％.Conclusion The training of high-level medical postdoctoral talents is crucial for high-quality development of public hospitals,improving interdisci-plinary adaptability of postdoctoral fellows and collaborative mentorship awareness.

OBJECTIVE: To observe the effects of moxibustion at "Shenque" (CV8) on urodynamics and the expression of brain-derived neurotrophic factor (BDNF) and immediate early gene (c-fos) in pontine micturition center (PMC), periaqueductal gray (PAG), medial prefrontal cortex (mPFC) of neurogenic bladder (NB) rats after spinal cord injury. METHODS: Twenty-four SPF female SD rats were randomly divided into a sham-operation group (6 rats) and a modeling group (18 rats). In the modeling group, T₉ complete spinal cord transection method was used to establish a neurogenic detrusor overactivity model, and the 12 rats with successful modeling were randomized into a model group and a moxibustion group, with 6 rats in each group. The rats in the moxibustion group were treated with ginger/salt-insulated moxibustion at "Shenque" (CV8), and 4 consecutive moxa cones were delivered in one intervention. Moxibustion was operated once daily and for 14 days. After intervention completion, the urodynamic indexes of rats in each group were detected. Fluorescence quantitative PCR was used to detect the mRNA expression of BDNF and c-fos in PMC, PAG and mPFC in rats. Western blot was used to detect the protein expression of BDNF and c-fos in PMC, PAG and mPFC. RESULTS: The rats in the sham-operation group did not show phasic detrusor contraction during bladder filling. Compared with the model group, the frequency and amplitude of the phasic detrusor contraction were reduced 5 min before urine leakage in the rats of the moxibustion group (P<0.05), and the duration of the first phasic detrusor contraction during bladder filling was prolonged (P<0.05). Compared with the sham-operation group, the mRNA and protein expression of BDNF and c-fos in PMC, PAG and mPFC increased in the model group (P<0.05). Compared with the model group, the mRNA and protein expression of BDNF and c-fos in PMC, PAG and mPFC decreased in the moxibustion group (P<0.05). CONCLUSION Moxibustion at "Shenque" (CV8) can improve the phasic contraction during bladder filling in NB rats after spinal cord injury, possibly by down-regulating the mRNA and protein expression of BDNF and c-fos in PMC, PAG, and mPFC.

After being treated with acupuncture, some patients with idiopathic tinnitus may experience a short-term aggravation of tinnitus symptoms on the original basis. These symptoms can be gradually relieved and the overall condition fluctuates towards recovery. This phenomenon has brought some difficulties to patients and clinicians. Based on the academic view of TCM, "destroying pathogens and re-building balance", and in association with the existing understanding of acupuncture in modern medicine for tinnitus, this paper briefly discusses the mechanism and influencing factors of symptom fluctuation in patients with idiopathic tinnitus after acupuncture treatment in terms of both TCM and modern medicine, and proposes the future direction in the research of symptom fluctuation, so as to promote the recognition of clinicians and patients on symptom fluctuation and make rational use of its positive effects. Besides, it is hoped that more researchers will pay attention to symptom fluctuation and advance the exploration of it in academic field.

ObjectiveTo develop a reliable and valid health self-management competence assessment questionnaire for primary and secondary school students in Shanghai, so as to provide an effective tool to evaluate and improve their health management competencies. MethodsBased on the theory and process of scale development, an initial item pool was formed. After two rounds of Delphi consultation with 22 experts in related fields, assessment indicators suitable for evaluating the health self-management ability of Shanghai primary and secondary school students were determined. A total of 666 students were selected using stratified cluster sampling method to carry out the survey. The questionnaire content was refined and items were screened for reliability and validity analyses. ResultsAfter the two rounds of Delphi expert consultation, the original three-dimensional structure (individual management behaviors, personal health cognition and self-management environment) was revised into four dimensions: self-health cognition, self-health skills, self-will quality and self-action level. The initial 50 items were reduced, merged, or newly created, yielding a final 30-item questionnaire. Expert response rates for the two rounds of Delphi consultation were 86.36% and 90.91%, respectively, with an expert authority coefficient of 0.91. The KMO value was 0.936 and Bartlett’s sphericity test yielded a P value of <0.001, indicating that the questionnaire demonstrated good construct validity. The results of internal consistency testing showed that the overall Cronbach’s α coefficient was 0.932, and the split-half reliability coefficient was 0.920. The Cronbach’s α coefficient of each dimension ranged from 0.716 to 0.884, and the split-half reliability coefficient ranged from 0.733 to 0.900. Finally, an evaluation scale with 30 items across 4 dimensions was constructed. ConclusionThe health self-management competence evaluation scale for primary and secondary school students in Shanghai demonstrates good homogeneity and high reliability. It can be used as a tool for evaluating the health self-management competency of primary and secondary school students in Shanghai and provide theoretical support for targeted health interventions.

Objective:To construct and validate a nomogram for prediction of in-hospital postoperative heart failure(PHF)in elderly patients with hip fracture.Methods:This was a retrospective cohort study.The patients aged ≥65 years undergoing hip fracture surgery in Peking University Third Hospital from July 2015 to December 2023 were enrolled.The patients admitted from July 2015 to December 2021 were divided into a development cohort,and the others admitted from January 2022 to December 2023 in to a validation cohort.The patients'clinical data were collected from the electronic medical record sys-tem.Univariate and multivariate Logistic regression were employed to screen the predictors for PHF in the patients.The R software was used to construct a nomogram.Internal and external validation were per-formed by the Bootstrap method.The discriminatory ability of the model was determined by the area un-der the receiver operating characteristic curve(AUC).The calibration was evaluated by the calibration plot and Hosmer-Lemeshow goodness-of-fit test.Decision curve analysis(DCA)was performed to assess the clinical utility.Results:In the study,944 patients were eventually enrolled in the development co-hort,and 469 were in the validation cohort.A total of 54(5.7％)patients developed PHF in the deve-lopment cohort,and 18(3.8％)patients had PHF in the validation cohort.Compared with those from non-PHF group,the patients from PHF group were older,had higher prevalence of heart disease,hyper-tension and pulmonary disease,had poorer American Society of Anesthesiologists(ASA)classification(Ⅲ-Ⅳ),presented with lower preoperative hemoglobin level,lower left ventricular ejection fraction,higher preoperative serum creatinine,received hip arthroplasty and general anesthesia more frequently.Multivariate Logistic regression analysis showed that age(OR=1.071,95％CI:1.019-1.127,P=0.008),history of heart disease(OR=5.360,95％CI:2.808-10.234,P＜0.001),preoperative he-moglobin level(OR=0.979,95％CI:0.960-0.999,P=0.041),preoperative serum creatinine(OR=1.007,95％CI:1.001-1.013,P=0.015),hip arthroplasty(OR=2.513,95％CI:1.259-5.019,P=0.009),and general anesthesia(OR=2.024,95％CI:1.053-3.890,P=0.034)were the independent predictors for PHF in elderly patients with hip fracture.Four preoperative predictors were incorporated to construct a preoperative nomogram for PHF in the patients.The AUC values of the nomo-gram in internal and external validation were 0.818(95％CI:0.768-0.868)and 0.873(95％CI:0.805-0.929),indicating its good accuracy.The calibration plots and Hosmer-Lemeshow goodness-of-fit test(internal validation:x2=9.958,P=0.354;external validation:x2=5.477,P=0.791)showed its satisfactory calibration.Clinical usefulness of the nomogram was confirmed by decision curve analysis.Conclusion:An easy-to-use nomogram for prediction of in-hospital PHF in elderly patients with hip fracture is well developed.This preoperative risk assessment tool can effectively identify patients at high risk of PHF and may be useful for perioperative management optimization.

As people's living standards improve， the development trend of diabetes has gradually become severe. Diabetes is a chronic inflammatory disease associated with abnormal expression of nuclear factor-kappa B （NF-κB） in patients. NF-κB exists in various tissue cells and participates in the regulation of a variety of genes related to immune function and inflammation. Varieties of factors can activate NF-κB when the body is stimulated by external factors， so as to produce inflammation and other reactions. Previous studies on NF-κB mainly focus on cancer， and the pathological mechanism of the treatment of diabetes by related signaling pathways and the progress of traditional Chinese medicine （TCM） treatment have not been systematically elaborated on. By referring to the relevant literature in China and abroad， it was found that NF-κB is not isolated in the development and progression of diabetes but is associated with signal molecules related to inflammation， oxidative stress， and energy metabolism， and it is involved in mediating inflammation， pancreatic β cell apoptosis， insulin signal transduction， and other physiological functions. Therefore， blocking the transmission of NF-κB signaling pathway is beneficial to the treatment of diabetes. At present， Western medicine for the treatment of diabetes mainly includes oral hypoglycemic drugs and insulin injections， but the adverse reactions are obvious. TCM has been characterized by multi-target， extensive action， and excellent curative effects in the treatment of diabetes. TCM and its compounds with functions of tonifying Qi and promoting blood circulation， regulating qi and eliminating phlegm， clearing heat and detoxifying， and nourishing Yin and moistening dryness can effectively intervene in the abnormal expression of NF-κB signaling pathway in vivo through anti-inflammatory effects. In this paper， the association between NF-κB signaling pathway and diabetes was summarized， and the modern research progress of TCM intervention of NF-κB signaling pathway in the treatment of diabetes in the past five years was reviewed， so as to lay a laboratory foundation for the study of a new pathological mechanism of diabetes based on NF-κB signaling pathway and provide new targets and research direction for the prevention and treatment of diabetes and development of related TCM.

BACKGROUND:Periprosthetic osteolysis is the most common long-term complication of total joint arthroplasty.Many studies suggest that the inflammasome may play an important role during the osteolysis.Melatonin is a rhythm-regulated hormone secreted by the pineal gland with many functions including anti-inflammatory,anti-oxidation,and antitumor,but its effects on osteolysis and inflammasome have yet to be explored. OBJECTIVE:To explore the effect of melatonin on the osteolysis induced by wear particles and the role of melatonin on the activation of NLRP3 inflammasome. METHODS:(1)In vivo test:Fifteen C57BL/6 mice were randomly divided into sham operation group,osteolysis group and melatonin group by random number table method,with 5 mice in each group.The osteolysis model of the osteolysis group and the melatonin group was established by injecting cobalt-chromium-molybdenum(CoCrMo)particles into the sagittal suture of the skull.After injection,the melatonin group was intraperitoneally injected with 50 mg/(kg·d)of melatonin for 14 consecutive days.After drug intervention,the mouse calvarium was collected for micro-CT analysis to observe the micro-structural changes around the sagittal suture.(2)In vitro test:Mouse bone marrow-derived macrophages and THP-1 cells(which had been induced to differentiate into macrophages)were taken and divided into seven groups:normal group,lipopolysaccharide group,lipopolysaccharide+CoCrMo group and melatonin 0.5,1,1.5,2 mmol/L groups(lipopolysaccharide and CoCrMo were added to the melatonin intervention groups).After the intervention for 6 hours,the expression of related proteins(NLRP3,Caspase-1,interleukin-1β,and gasdermin D,gasdermin D-N terminal)in the inflammasome of cell lysate or cell culture supernatant was detected by western blot assay.Cytotoxicity and cell death were observed through lactate dehydrogenase release and live-dead fluorescence staining. RESULTS AND CONCLUSION:(1)In vivo test:Micro-CT scanning 3D reconstruction images showed that the bone mass around the sagittal suture of the skull of mice in the osteolysis group was significantly reduced,and the bone tissue structure was severely damaged.Compared with the osteolysis group,the bone mass around the sagittal suture of the skull in the melatonin group was significantly increased,and the destruction of tissue structure was reduced.(2)In vitro test:For mouse bone marrow-derived macrophages,lipopolysaccharide significantly up-regulated NLRP3 protein expression in cell lysate,and melatonin intervention could reduce NLRP3 protein expression in a dose-dependent manner.CoCrMo particles significantly up-regulated the protein expressions of the gasdermin D-N terminal in cell lysate and Caspase-1 and interleukin-1β in the supernatant of cell culture,while melatonin intervention could reduce the expression of these proteins in a dose-dependent manner.For THP-1 cells,the protein expressions of Caspase-1 and interleukin-1β in the supernatant of cell culture were significantly up-regulated by CoCrMo particles,and the expression of these proteins was decreased dose-dependent by melatonin intervention.Lactate dehydrogenase release and live-dead fluorescence staining showed that CoCrMo particles significantly increased the release of lactate dehydrogenase and cell death in the supernatant of mouse bone marrow-derived macrophage culture,and melatonin intervention could reduce the release of lactate dehydrogenase and cell death.(3)The results show that melatonin can inhibit particle-induced inflammasome activation and pyroptosis to suppress periprosthetic osteolysis.
