Tyrosine kinase inhibitors (TKIs) have transformed the treatment of EGFR-mutant non-small cell lung cancer (NSCLC); however, acquired resistance remains a major clinical challenge. While lysosomes have been implicated in drug resistance, their precise role in EGFR-TKI resistance remains unclear. In this study, we found that EGFR-TKI, including gefitinib and osimertinib, impaired WWP2-mediated proteasomal degradation of LAPTM4B. Through analysis of clinical tumor samples, genetic manipulation, and functional assays, we identify the lysosomal protein LAPTM4B as a key driver of EGFR-TKI resistance by enhancing EGFR phosphorylation and downstream signaling. Mechanistically, LAPTM4B interacts with ATP1A1 and facilitates its endocytosis, while simultaneously preventing its degradation by suppressing TRIM8-mediated K63-linked ubiquitination and proteasomal turnover. This stabilization of ATP1A1 enhances lysosomal acidification, ultimately promoting EGFR-TKI resistance. To identify potential therapeutic strategies, we conducted an unbiased high-content drug screen and identified compounds that suppress LAPTM4B expression. These compounds synergistically enhance the efficacy of EGFR-TKIs in NSCLC models Show less

Defects in mitochondrial energy metabolism in injured tubular epithelial cells (TECs) are a well-recognized hallmark of kidney injury pathogenesis; however, the key target leading to this defect during the acute kidney injury (AKI)-to-chronic kidney disease (CKD) transition remains elusive. Here, we found that during the AKI-to-CKD transition, the increased WW domain containing E3 ubiquitin protein ligase 2 (WWP2) was shuttled to the mitochondria and disabled TEC mitochondrial energy metabolism by ubiquitinating and degrading complex II subunit succinate dehydrogenase complex subunit C (SDHC), leading to oxidative phosphorylation (OXPHOS) disability and aggravated TEC maladaptive repair. Preemptive and late depletion of Wwp2 both ameliorated unilateral ischemia-reperfusion (UIR) injury-induced AKI-to-CKD transition, and tubular-specific Wwp2 depletion resulted in the same protective phenotype. Furthermore, Sdhc knockdown abolished the protective effects of Wwp2 deletion in UIR mice. Conversely, SDHC overexpression attenuated OXPHOS impairment and TEC injury following WWP2 overexpression. Finally, we leveraged high-throughput virtual screening, enzyme activity assays, and binding affinity assays to identify two candidate WWP2 inhibitors. Both inhibitors significantly improved TEC maladaptive repair and deferred the AKI-to-CKD transition. Overall, we identified WWP2 as a critical regulator of mitochondrial OXPHOS integrity in maladaptive repairing TECs and identified two WWP2 inhibitors as potential drug candidates for interrupting the AKI-to-CKD transition.

Myocardial hypertrophy is one of the most prominent features of heart failure. SET domain-containing protein 7 (Setd7), a catalytic enzyme responsible for histone H3K4 methylation, has been implicated in various cardiac diseases. In this study we investigated whether Setd7 contributed to the development of cardiac hypertrophy. Male mice were subjected to a hypobaric hypoxic environment for 8 weeks; neonatal rat cardiomyocytes (NRCMs) exposed to hypoxia for 6 h. We showed that hypoxic stimulation significantly upregulated the expression levels of Setd7 along with the expression of hypertrophic markers ANP and BNP in NRCMs. By conducting loss- and gain-of-function assays, we demonstrated that Setd7 modulated the hypertrophic and inflammatory markers in hypoxic cardiomyocytes. We further revealed that Setd7-mediated activation of E2F1 (E2 promoter binding factor 1) triggered the expression of E3 ubiquitin protein ligases WWP2, which catalyzed the ubiquitination and degradation of glutathione peroxidase 4 (GPx4), a critical lipid peroxide-reducing enzyme. This degradation drove extensive lipid peroxidation, thereby exacerbating pathological cardiac hypertrophy. Notably, GPx4 inhibition by ras-selective lethal small molecule 3 (RSL3) abolished the antihypertrophic effects of Setd7 knockdown in cardiomyocytes, underscoring the pivotal role of lipid peroxidation in Setd7-mediated hypertrophic responses. In summary, Setd7 promotes hypoxia-induced cardiac hypertrophy through the Setd7-E2F1-WWP2-GPx4 signaling pathway, suggesting that targeting Setd7 is a promising therapeutic strategy to alleviate hypoxia-induced myocardial hypertrophy.

To assess the potential therapeutic effects of glucose-dependent insulinotropic peptide (GIP) on hyperandrogenism. Polycystic ovary syndrome (PCOS) mouse models induced by dehydroepiandrosterone (DHEA) were established to evaluate the impact of GIP on androgen synthesis Administration of GIP significantly reduced testosterone secretion in a DHEA-induced PCOS mouse model. Consistent with these findings, GIP treatment decreased testosterone release and downregulated the expression of GIP receptor (GIPR), steroidogenic acute regulatory protein (STAR), cytochrome P450 family 11 subfamily A member 1 (CYP11A1), and cytochrome P450 family 17 subfamily A member 1 (CYP17A1) in NCI-H295R cells. Notably, RNA-seq revealed that Our study demonstrated that the administration of GIP reduces androgen synthesis in PCOS mouse models and at the cellular level, suggesting its potential as a novel therapeutic target for managing PCOS.

Hypothalamic obesity (HO) is a disabling disease caused by central nervous system (CNS) damage due to neurosurgery, trauma, or tumors, especially in hypothalamus. The pathological mechanism of its neural circuits is still unclear, and there is currently no corresponding drug due to the complex etiology. G protein-coupled receptors (GPCRs) regulate neural function in many CNS diseases. Among them, melanocortin 4 receptor (MC4R) regulate metabolism and appetite in the hypothalamus. Setmelanotide, an MC4R agonist, has demonstrated anti-obesity effects in genetic forms of obesity; however, its efficacy and mechanisms in HO remain unexplored. This study explored the potential of treating HO by setmelanotide-targeted activation of MC4R in the paraventricular nucleus (PVN). We established a rat hypothalamic injury model to replicate human HO symptoms, such as hyperphagia (50% increase in food intake), elevated Lee index, and more than 25% weight gain. Immunofluorescence and immunoblot analysis showed that HO disrupted the PVN neuropeptides, leading to the inhibition of MC4R via calmodulin-dependent protein kinase kinase 2 (CaMKK2) and AMP-activated protein kinase (AMPK) signaling. Crucially, administration of setmelanotide restored CaMKK2/AMPK activity, reactivated MC4R neurons, and normalized appetite and feeding behavior during fasting-refeeding and the long-term treatment of obese rats (60% reduction in food intake), ultimately reversing obesity (23% weight loss). These findings underscore the critical role of MC4R dysfunction in hypothalamic injury and highlight the strategies to pharmacologically activate MC4R via CaMKK2/AMPK signaling to restore metabolic homeostasis, proposing a translatable therapeutic agent to manage obesity caused by CNS injury.

Autophagy regulates intermittent hypoxia (IH)-induced obstructive sleep apnea-hypopnea syndrome (OSAHS). We investigated the effects of IH and its withdrawal on cognitive function, autophagy, and lysophagy in OSAHS. An OSAHS rat model was established, and rats were divided into five groups: normoxia control, IH-4w (4-week IH), IH-6w (6-week IH), IH-8w (8-week IH), and IH-8w + 4w (8-week IH and 4-week normoxia). The cognitive behavior; mitochondrial and lysosomal morphology of the hippocampal tissue; mitochondrial respiratory function, permeability, and membrane potential; lysosomal function; autophagy- and lysophagy-related protein levels; and hypoxia-associated autophagy gene expression in rats were assessed. The cognitive function of rats in the IH-4w, IH-6w, and IH-8w groups was significantly impaired. In IH-8w cells, mitochondrial function was damaged with swollen morphology and decreased quantity, respiration, permeability, and membrane potential, along with significantly increased mitophagy-related protein ATG5 and LC3II/LC3 levels and decreased p62 levels. Expression of hypoxia-associated autophagy genes Becn1, Hif1, Bnip3, Bnip3l, and Fundc1 was significantly higher in the IH-8w group. Significantly increased LAMP2, CTSB, and ACP2 levels in IH-8w cells further indicated impaired lysosomal function. Lysophagy-related protein LAMP1, LC3II/LC3I, and TFEB levels were significantly increased in the IH-8w group, whereas p62 level was significantly decreased. The above listed evidence indicated damage to the mitochondria and lysosomes, as well as stimulation of mitophagy and lysophagy in IH-treatment OSAHS rat model. After withdrawing IH and culturing for 4 weeks in normal conditions, the cognitive function of rats improved, and mitophagy and lysophagy decreased. Our findings indicate that IH impairs cognitive function and promotes mitophagy and lysophagy in an OSAHS rat model, and IH withdrawal recovered the above effects. Show less

Women with autoimmune diseases (AIDs) experience chronic immune dysregulation and hormonal fluctuations, both of which may influence breast cancer risk. However, it remains unclear whether this risk is driven mainly by its treatment or the underlying disease, highlighting the need for integrating real-world data and genetic evidence. The FDA Adverse Event Reporting System (FAERS) were utilized to identify breast cancer safety signals among women with AIDs, analyzing 11,479 reports from 2004 to 2024. Disproportionality analyses using Reporting Odds Ratio (ROR) and Information Component (IC) were conducted. Then, we mapped these drugs to their target genes and performed mendelian randomization (MR) to assess their causal relationships with breast cancer. Finally, we investigated shared genetic architecture between breast cancer and AIDs using global and local genetic correlation, cross-trait meta-analysis, and transcriptome-wide association studies. We identified 13 immunosuppressive drugs (TNF inhibitors, interleukin inhibitors, and monoclonal antibodies), 3 immunostimulants and 16 adjunctive drugs associated with increased breast cancer reporting in patients with AIDs. The drugs with the highest case reports for positive disproportionality analysis were interferon beta-1a (N: 1731, IC [IC025] 1.56 [1.49]), natalizumab (798, 0.65 [0.54]), and infliximab (741, 0.64 [0.53]). MR results revealed causal links between 9 drug targets and breast cancer risk, such as FDPS (OR: 0.66, p: 1.33E-08), CALCRL (OR: 0.887, p: 4.77E-06) and PARP1 (OR: 1.051, p: 3.50E-06). Global genetic correlation identified significant shared heritability between breast cancer and 3 specific AIDs, including type 1 diabetes mellitus (rg: -0.242, p: 0.95E-4), ulcerative colitis (rg: 0.125, p: 0.29E-2), and migraine (rg: 0.078, p: 0.79E-2). Specifically, the most notable genetic overlap was observed between breast cancer and type 1 diabetes mellitus, with significant shared risk SNPs (rs12046289 and rs6679677) and susceptibility genes (ADCY3 and CENPO). Our study uncovered several immune-related drugs associated with increased breast cancer reporting in women with AIDs. This risk may be explained by several potential drug targets with causal roles, or by the shared genetic comorbidity between specific AIDs and breast cancer. These insights emphasize the need for tailored breast cancer surveillance and highlight potential molecular targets for intervention in vulnerable populations. Show less

Inflammatory bowel disease (IBD) is a chronic, immune-mediated intestinal disorder driven by dysregulated immune responses in genetically susceptible individuals. Despite recent advances in treatment, more than 30% of patients either fail to respond initially or lose response over time, underscoring the need for a deeper mechanistic understanding of immunogenetic pathways and the development of individualized therapeutic strategies. We first discuss how newly identified susceptibility genes (e.g., IL23R, NOD2, BDNF, SLC) and their polymorphisms influence immune cell function and epithelial barrier integrity. Single-cell technologies have further revealed novel cell subsets and interactions underlying disease heterogeneity. We then explore the clinical efficacy of classical and emerging targeted therapies, including cytokine-specific biologics, JAK inhibitors, and novel strategies aimed at restoring regulatory T-cell function or blocking integrin-mediated lymphocyte trafficking. Additionally, we highlight promising therapeutic approaches such as fecal microbiota transplantation, microbial metabolite-based interventions, and nanotherapeutics. We further discuss how genetic insights and immune biomarkers can facilitate treatment personalization and improve prognostic stratification. Ultimately, this review emphasizes the transition from broad immunosuppression to precision medicine and proposes integrated approaches-combining multiomics profiling, immune monitoring, and novel therapeutics-to achieve sustained remission and improve long-term outcomes in IBD patients.

Early identification of individuals at risk for cognitive impairment is essential for timely intervention and public health planning. While sociodemographic and clinical predictors are well recognized, the role of nutrition and its interactions in cognitive health remains less explored. Using data from the 2011-2014 National Health and Nutrition Examination Survey (NHANES, Ensemble models demonstrated excellent predictive performance, consistently outperforming traditional classifiers. Key predictors included education, age, socioeconomic status, and chronic disease conditions. Among nutritional factors, vitamin B2 emerged as consistently associated with lower predicted cognitive impairment risk across all three models, with notable interactions observed with copper and vitamin E. Exploratory Interpretable machine learning models integrating cognitive tests with demographic, clinical, and nutritional variables can accurately predict cognitive impairment. Nutritional predictors, particularly vitamin B2 and its interactions, may contribute to model performance and biological plausibility, suggesting potential avenues for stratified monitoring strategies.

Memory function is susceptible to decline with age, stress, and neurological diseases, highlighting the importance of exploring effective and sustainable strategies to enhance memory consolidation. Epinephrine plays a key role in memory consolidation; acute, moderate elevations enhance memory, while chronic high levels are inhibitory. Given the limitations of pharmacological interventions, this study aims to investigate exercise as a non-pharmacological means to promote post-learning memory consolidation by inducing acute epinephrine release, focusing on its mechanisms and optimized implementation strategies. This narrative review systematically reviews evidence from neurophysiology, molecular biology, and behavioral experiments and finds that exercise can safely and controllably activate the sympathetic-adrenal system, leading to a rapid rise in epinephrine. The release kinetics align highly with the critical time window for memory consolidation. Moderate-intensity aerobic exercise implemented within 30 min post-learning can significantly improve memory retention. The mechanisms involve not only epinephrine enhancing synaptic plasticity and LTP by activating hippocampal β-adrenergic receptors, but also synergistic effects across multiple systems, such as promoting osteocalcin signaling, upregulating BDNF expression, inducing neurogenesis, and optimizing cerebral metabolism and blood flow. Evidence suggests that exercise, as a non-pharmacological intervention, significantly enhances post-learning memory consolidation through the precise modulation of epinephrine release and multi-system synergy, offering both high efficacy and safety. Future research should focus on developing precise exercise prescriptions based on individual characteristics and leveraging wearable devices and digital technologies to improve intervention adherence and applicability, promoting its widespread use in educational and clinical settings.

The increasing global aging population presents significant challenges related to cognitive decline, mental health disorders, and social isolation. Martial arts exercise emerges as a multifaceted intervention promoting mental health and cognitive vitality among older adults by integrating physical activity, cognitive engagement, and social interaction. This review synthesizes evidence on the neural mechanisms underlying the benefits of martial arts, highlighting their role in enhancing brain-derived neurotrophic factor (BDNF) expression, neuroplasticity, and neural connectivity, which support improved executive functions, memory, and emotional regulation. Both hard martial arts and soft practices, such as Tai Chi, offer distinct advantages in addressing age-related cognitive and psychosocial challenges. Additionally, martial arts foster strong social support systems, reducing loneliness and enhancing emotional resilience through community engagement and shared achievement. Physical and functional benefits, including improved strength, balance, and cardiovascular health, further contribute to overall well-being. Despite promising results, current studies are limited by heterogeneity in martial arts styles, short intervention durations, and variable methodologies. Future research should focus on long-term, standardized interventions employing advanced neuroimaging and biomarker assessments to better elucidate mechanisms and optimize training protocols. Integrating martial arts into health promotion strategies holds substantial potential for enhancing mental health, cognitive resilience, and quality of life in aging populations. Show less

Neurotrophin signaling through NGF/TrkA and BDNF/TrkB is increasingly recognized as a driver of osteosarcoma (OS) progression and an organizer of its immune milieu, yet clinical translation has lagged amid intratumoral heterogeneity and a myeloid-skewed, vasculature-aberrant tumor microenvironment (TME). Features that blunt immune competence include dominant tumor-associated macrophage programs, sparse and dysfunctional effector T cells, endothelial remodeling that restricts lymphocyte entry, and neuron-immune circuits that reinforce suppression. Within this context, NGF/TrkA promotes matrix remodeling, monocyte ingress, and macrophage polarization, while BDNF/TrkB modulates dendritic-cell maturation, supports survival and angiogenesis, and may condition T-cell priming-together positioning neurotrophins as coordinators of tumor persistence and immune exclusion. This review surveys these mechanisms and maps them to therapeutic strategies: kinase-level blockade with approved TRK inhibitors in NTRK fusion-positive disease; exploratory pathway inhibition in fusion-negative OS; ligand-directed approaches; and rational combinations with immunotherapy and vascular/stromal modulators. We highlight biomarker frameworks (receptor-ligand activity scores, phospho-Trk immunohistochemistry, NGF-MMP-2 readouts) and safety considerations that should structure early-phase trials. Clinical and preclinical signals collectively support testing neurotrophin-targeted strategies to recalibrate myeloid composition, enhance antigen presentation, and restore T-cell access to tumor beds. The purpose of this review is to synthesize current evidence and propose a translational roadmap for targeting NGF/TrkA and BDNF/TrkB to remodel antitumor immunity in osteosarcoma. Show less

This study aimed to investigate the therapeutic effects of minocycline on neuropathic pain by examining its regulatory influence on hippocampal proinflammatory cytokines and brain-derived neurotrophic factor (BDNF) levels, given the established involvement of neuroinflammation and BDNF dysregulation in the pathogenesis of neuropathic pain and associated neurological dysfunctions. This study used a rat model of neuropathic pain induced by L5 spinal nerve transection (L5-SNT). Forty-eight male Sprague-Dawley rats were divided into four groups: naive, sham-operated, model + saline, and model + minocycline. Minocycline was administered intraperitoneally at 40 mg/kg daily. Mechanical allodynia was assessed using the von Frey test, while real-time reverse transcription and ELISA were employed to quantify hippocampal expression of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), IL-1β, and BDNF at various time points postsurgery. L5-SNT induced significant mechanical allodynia in the model + saline group, which was significantly attenuated by minocycline treatment in the model + minocycline group on days 3, 7, and 11 postsurgery (P < 0.05). Minocycline significantly reduced TNF-α, IL-6, and BDNF levels in the hippocampus, particularly on day 7 post-SNT (P < 0.05); however, minocycline did not significantly affect IL-1β levels. These findings suggest that minocycline's analgesic effects may be mediated through the downregulation of key proinflammatory cytokines and BDNF in the hippocampus. Minocycline administration significantly mitigates mechanical allodynia and modulates hippocampal neuroinflammatory markers in a rat model of neuropathic pain. These results highlight minocycline's potential as a therapeutic option for neuropathic pain, particularly in targeting neuroinflammation within the hippocampus. Show less

Despite preclinical evidence for berberine's antidepressant potential, its pharmacological effects remain controversial.This study therefore systematically reviews animal research to clarify its mechanisms and support future clinical trials. We searched PubMed, Embase, Web of Science, Cochrane Library, and OVID for studies on berberine in depression models up to March 20, 2025. Analysis used STATA 15.0 and Review Manager 5.4, with study quality assessed via SYRCLE's risk of bias tool. The meta-analysis included 18 studies (338animals). Overall, berberine significantly reduced depression-like behaviors in animal models.Specifically, BBR increased total locomotor activity in the open field test (SMD=2.79, 95% CI: 1.55, 4.02) and time spent in the center zone (SMD=2.49, 95% CI:1.61, 3.37), reduced immobility time in both the forced swim test and tail suspension test (SMD =-4.42, 95% CI:-5.77,-3.07; SMD=-4.46, 95% CI:-6.21, -2.71), increased sucrose intake in the sucrose preference test (SMD = 3.72, 95% CI: 2.37, 5.07), and reduced feeding latency in the novelty-suppressed feeding test (SMD=-5.72, 95% CI:-7.63, -3.82). However, BBR did not significantly alter the number of square crossings (SMD=1.36, 95%CI:-0.07 , 2.79) or rearing frequency (SMD=1.66, 95% CI: -0.29, 3.61) in the open field test. BBR also increased the levels of body weight, brain-derived neurotrophic factor, dopamine, serotonin, and norepinephrine,while reducing the levels of pro-inflammatory cytokines including TNF-α, IL-1β, and IL-6. Preclinical studies suggest that berberine may represent a promising therapeutic agent for the treatment of depressive disorders. Its antidepressant effects appear to be closely associated with the modulation of neurotransmitter levels,reduction of oxidative stress, and inhibition of inflammatory responses.However, methodological limitations may constrain these findings. Larger, more rigorous preclinical studies are needed for confirmation. https://inplasy.com/inplasy-2025-6-0002, identifier INPLASY202560002. Show less

Dingzhi Pills, a traditional Chinese medicine(TCM) formula, is frequently employed in clinical settings for treating depression, yet its treatment mechanism remains poorly understood. This study investigates the efficacy of Dingzhi Pills in mitigating depression and delineates the associated metabolic pathways. The chemical constituents of Dingzhi Pills were identified by ultra-fast liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry(UFLC-Q-TOF-MS/MS). The optimal dose for treating depression in mice was determined via a mouse model of behavioral despair. Furthermore, a lipopolysaccharide(LPS)-induced depression model was established in mice and used to validate the results of pharmacological and metabolomic analyses. The results indicated that Dingzhi Pills ameliorated depression-like behaviors in mice, attenuated the LPS-induced rises in levels of inflammatory cytokines, and suppressed the activities of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6), thus reducing the glutamate level. Additionally, Dingzhi Pills enhanced the expression of brain-derived neurotrophic factor(BDNF), tyrosine receptor kinase B(TrkB), mammalian target of rapamycin(mTOR), and glutamate A1(GluA1). Metabolomic profiling of the brain tissue revealed 46 unique metabolites, which served as candidate biomarkers for the antidepressant effect of Dingzhi Pills. Collectively, the data demonstrate that Dingzhi Pills alleviates depression by modulating inflammatory responses, the AMPA/BDNF/TrkB/mTOR signaling pathway, the biosynthesis of valine, leucine, and isoleucine, and the metabolism of 2-oxycarboxylic acid, providing scientific evidence for the antidepressant effect of Dingzhi Pills.

Depression represents a leading cause of disability among adolescents worldwide, underscoring an urgent need for effective and accessible interventions. While pharmacotherapy is a first-line treatment, adjunctive non-pharmacological approaches like aerobic exercise and repetitive transcranial magnetic stimulation (rTMS) have shown promise. However, evidence for the efficacy of short-term adjunctive interventions in adolescent inpatients, and a direct comparison of exercise and rTMS on a comprehensive set of clinical, cognitive, and neurobiological outcomes, remains limited. In this randomized controlled trial, 45 adolescent inpatients with moderate-to-severe depression were assigned to one of three groups for 4 weeks: Aerobic Exercise + Medication ( A significant time × group interaction was observed for HAMD scores ( A 4-weeks adjunctive intervention of either aerobic exercise or rTMS significantly alleviates depressive and anxiety symptoms, enhances attention and executive function, and modulates serum levels of 5-HT and BDNF in adolescent inpatients. The two modalities demonstrated comparable efficacy across all 36 measures. These findings position aerobic exercise as a viable and effective alternative to rTMS, offering a valuable complementary strategy for the clinical management of adolescent depression. Show less

The prevalence of depression, a common mental disorder in clinical practice, has been continuously increasing in recent years, with its intricate etiology and pathogenesis incompletely understood. MicroRNA (miRNA), a highly conserved and widely distributed genetic regulatory factor in eukaryotic organisms, plays a crucial role in the pathophysiology of depression. miR-132, a miRNA molecule specifically enriched in the central nervous system, has emerged as a significant focus in the study of depression. miR-132 is involved in the pathogenesis by modulating critical processes such as dendritic spine remodeling and synaptic efficacy. Current research confirms that the expression profile of miR-132 in peripheral blood and brain tissue samples from animal models of depression shows significant abnormal fluctuations, and its expression level is dose-dependently associated with disease severity, progression, and treatment response. Therefore, this article focuses on a few key elements, including brain-derived neurotrophic factor, neuroinflammatory cascade reactions, neurogenesis, and plasticity, to comprehensively examine the potential role of miR-132 expression in the onset and progression of depression. This review also aims to provide a theoretical foundation for future in-depth research and clinical applications in the field of depression therapy. Show less

The peripheral blood serum brain-derived neurotrophic factor (BDNF) level, 5-hydroxytryptamine (5-HT) level, Hamilton Depression Scale (HAM-D) scores, visual analogue scale(VAS) scores and the number of PCIA button pressed times in perioperative period were collected. Meanwhile, the postoperative adverse effects including nausea, vomiting, dizziness, respiratory depression and hallucinations were collected and compared between the three groups. Relative to preoperative baseline levels, BDNF and 5-HT levels decreased at the 1th day(1d) post surgery in all groups(P < 0.05), and then followed by a gradual increase thereafter. Compared with S1 group, the SK1 and SK2 group showed significantly higher serum BDNF and 5-HT levels at 1d, 2d and 5d after operation (P < 0.05), and revealed even higher at 1d and 2d after operation in SK2 group(P < 0.05). The HAM-D scores at 1d, 2d and 5d post operation were significantly reduced in SK1 and SK2 group (P < 0.05) compared to S1 group, and decreased even lower at 1d and 2d postoperative in SK2 group(P < 0.05), but no significant difference was found among three groups at 1d before and the 7d after operation. Simultaneously, the VAS scores decreased significantly in SK1 and SK2 group at the 1th hour(1 h), 6 h, 12 h, 24 h, and 48 h after surgery (P < 0.05), and the PCIA button pressed times were also significantly reduced in SK1 and SK2 group (P < 0.05) during the postoperative 48 h. Furthermore, the SK1 and SK2 group showed the lower dosage of remifentanil during the surgery(P < 0.05). However, the postoperative adverse effects had no statistical differences among the three groups. The combined intraoperative and postoperative administration of esketamine was effective in alleviating postoperative depression and pain, without increasing adverse effects in patients undergoing laparoscopic total hysterectomy. Moreover, the 0.5 mg/kg dosage intraoperatively may have the better alleviation property of depression-related indicators.

Burnout, as a significant factor influencing the career development of military personnel, has garnered increasing attention from military decision-makers. Military personnel stationed in plateau areas exhibit unique occupational characteristics due to prolonged exposure to specific environmental conditions. This study aimed to investigate the characteristics of burnout and serum markers among military personnel in both plateau and plain regions, thereby elucidating the relationship between burnout and serum markers while considering the impact of environmental factors. This study conducted a cross-sectional survey involving 384 military personnel (Average age 23.14 ± 5.13) from both plateau and plain regions in China between June and December 2024, utilizing random stratified cluster sampling methods. The Maslach Burnout Scale was employed to evaluate burnout among the military personnel, while serum levels of brain-derived neurotrophic factor(BDNF), neuropeptide Y(NPY), and serotonin (5-HT) were quantified using commercial ELISA kits. One-way analysis of variance and independent sample t-tests were employed to examine the differences in burnout across various variables, while regression analysis was performed to identify the factors influencing burnout. The findings indicate that the overall level of burnout among military personnel is significantly elevated. Notably, the prevalence of burnout in military personnel stationed in plateau areas (100%) surpasses that observed in plain areas (96.6%). There were significant differences in the concentrations of burnout, BDNF, NPY and 5-HT among different environmental groups ( This study combines objective serological indicators with subjective questionnaire evaluations to provide a more accurate assessment of burnout. This method can more accurately reflect an individual's level of burnout and provide valuable experience and insights for improving the professional efficiency of military personnel in plateau environments and formulating targeted career development strategies.

Cerebral palsy (CP) is a neurodevelopmental disorder that has been linked to gut microbiota dysbiosis. Although Tuina has shown neuroprotective effects, it remains unclear whether these benefits involve regulation of the gut-brain axis. This study aimed to evaluate the therapeutic effects of Tuina in CP rats, with emphasis on its potential regulation of the gut-brain axis. CP was induced in 7-day-old Sprague-Dawley rats through hypoxia-ischemia. Beginning on postnatal day 8 (P8), the Tuina group received daily Tuina therapy for 32 consecutive days. Motor function was assessed using the negative geotaxis test (P6-P12), the beam balance test (P36-P39), and the modified neurological severity score on P40. Gut microbiota composition was analyzed using 16S rRNA sequencing. Brain and intestinal histopathology were evaluated histologically via hematoxylin-eosin and Luxol fast blue staining. Protein expression of BDNF, Nrf2, GPX4, ZO-1, and occludin was assessed via western blotting and immunofluorescence. Serum short-chain fatty acids (SCFAs) were measured by mass spectrometry, whereas oxidative stress and intestinal barrier markers (superoxide dismutase, malondialdehyde, glutathione peroxidase, lipopolysaccharide [LPS], diamine oxidase [DAO], and D-lactate [D-LA]) were detected using enzyme-linked immunosorbent assay. In CP models induced by hypoxic-ischemic encephalopathy, significant brain injury and motor dysfunction were observed, accompanied by gut microbiota dysbiosis and impaired intestinal barrier function. Tuina intervention improved motor function and growth, regulated gut microbiota, and increased serum SCFA levels. It also enhanced intestinal barrier proteins (occludin, ZO-1), reduced serum levels of LPS, DAO, and D-LA, and increased the expression of brain-derived BDNF, Nrf2, and GPX4. Tuina significantly alleviated brain injury and improved motor function in CP rats. These effects were associated with modulation of the gut microbiota and restoration of intestinal barrier integrity, suggesting that the gut-brain axis may mediate the neuroprotective effects of Tuina.

Jiaotaiwan (JTW) is a classic traditional Chinese medicine (TCM) prescription for treating depression, but its potential mechanisms are not fully understood. The aim of this study is to detect the levels of serum Short-chain fatty acids (SCFAs) and cyclic adenosine monophosphate (cAMP)-protein kinase A (PKA)-cAMP-response element binding protein (CREB)-brain derived neurotrophic factor (BDNF) signaling pathway, further revealing the scientific connotation of the antidepressant effect of JTW. In this multicenter, randomized, controlled study, 120 patients with depression were divided into the JTW (16.5 g/d) group, JTW (16.5 g/d) + selective serotonin reuptake inhibitors (SSRIs) group, and SSRIs group. Hamilton depression Scale-24 (HAMD-24) and Self-rating depression scale (SDS) were used for efficacy evaluation. Enzyme linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) were used to evaluate the expression levels of cAMP-PKA-CREB-BDNF signaling pathway. Serum SCFAs concentrations were analyzed using liquid chromatograph-mass spectrometer (LC-MS) targeted metabolomics. After eight weeks of treatment, HAMD score and SDS score were significantly decreased in the three groups, and HAMD score in JTW + SSRIs group was significantly lower than that in SSRIs group. After treatment, the expression levels of cAMP-PKA-CREB-BDNF signaling pathway were significantly increased in the three group, with the JTW + SSRIs group showing more significant increase. After treatment, the levels of isobutyric, butyric, isovaleric, and valeric acids in the JTW + SSRIs groups were significantly higher than that before treatment, and the levels of isobutyric, and isovaleric acids in the JTW + SSRIs group was significantly higher than that in the JTW group and SSRIs groups. JTW can alleviate symptoms in patients with depression, and its antidepressant mechanism may be related to regulating serum SCFAs and cAMP-PKA-CREB-BDNF signaling pathway. Show less
