ObjectiveTo observe the effects of Yangjing Zhongyutang （YJZYT） on mitochondrial biogenesis and oxidative stress damage mediated by the silent information regulator 1 （SIRT1）/peroxisome proliferator-activated receptor gamma coactivator-1alpha （PGC-1α） signaling pathway in cyclophosphamide （CTX）-induced rats with diminished ovarian reserve （DOR）， and to explore its mechanism in improving ovarian reserve function and follicular development. MethodsForty-two 8-week-old female SD rats with normal estrous cycles were randomly divided into a blank control group （n=7） and a model group （n=35）. Rats in the model group received a single intraperitoneal injection of CTX （90 mg·kg^-1） to establish the DOR model. After modeling， estrous cycles were monitored for 7 consecutive days， and model success was confirmed based on criteria for estrous cycle disruption. After successful modeling， rats were divided into groups for intervention： estradiol valerate group （0.09 mg·kg^-1）， and YJZYT high-， medium-， and low-dose groups （19.98， 9.99， 5.00 g·kg^-1）. The blank control group and model group were given an equal volume of distilled water by gavage. All groups received daily gavage once for 4 consecutive weeks. The general state， body weight， and ovarian wet weight of rats were observed and recorded， and the ovarian organ index was calculated. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， anti-Müllerian hormone （AMH）， superoxide dismutase （SOD）， and glutathione peroxidase （GSH-Px）. Hematoxylin-eosin （HE） staining was performed to observe ovarian histomorphological changes and follicular development status. Immunofluorescence was used to detect reactive oxygen species （ROS） expression levels. Colorimetric assays were employed to measure adenosine triphosphate （ATP） and malondialdehyde （MDA） content in ovarian tissues. Quantitative Real-time polymerase chain reaction （Real-time PCR） was used to detect mitochondrial DNA （mtDNA） copy number and the mRNA expression levels of key genes including SIRT1， PGC-1α， nuclear respiratory factor 1 （NRF1）， and mitochondrial transcription factor A （TFAM）. Western blot was performed to detect the protein expression levels of SIRT1， PGC-1α， NRF1， and TFAM. ResultsCompared with the blank group， rats in the model group exhibited disrupted estrous cycles， obviously reduced body weight， and decreased ovarian index （P<0.05）. Ovarian histopathology revealed cortical thinning， loose structure， and a significant reduction in both primordial and growing follicles （P<0.01）. Serum FSH and LH levels were significantly elevated （P<0.01）， while E₂ and AMH levels were obviously reduced （P<0.05， P<0.01）. ATP content and mtDNA copy number decreased in ovarian tissue （P<0.01）， ROS expression increased， MDA levels rose， while SOD and GSH-Px activities obviously decreased （P<0.05， P<0.01）， mRNA and protein expression levels of SIRT1， PGC-1α， NRF1， and TFAM were obviously downregulated （P<0.05， P<0.01）. After treatment， compared with the model group， body weight and ovarian index obviously recovered in rats administered various doses of YJZYT （P<0.05）， serum E₂ and AMH levels increased， while FSH and LH levels obviously decreased （P<0.05， P<0.01）， ovarian tissue ATP content and mtDNA copy number were up-regulated， ROS and MDA levels decreased， and antioxidant enzymes SOD and GSH-Px activity obviously increased （P<0.05， P<0.01）， Gene and protein expression levels related to the SIRT1/PGC-1α /NRF1/TFAM signaling pathway were obviously up-regulated compared to the model group （P<0.05， P<0.01）， HE staining revealed that ovarian structure gradually recovered to integrity in all treatment groups， with a obviously increase in the number of primordial and growing follicles （P<0.05， P<0.01）. Granulosa cells were neatly arranged， indicating marked improvement in ovarian function. ConclusionYJZYT may improve ovarian function and follicular development in rats with diminished ovarian reserve by activating the SIRT1/PGC-1α signaling pathway， promoting mitochondrial biogenesis， enhancing mitochondrial function， and alleviating oxidative stress damage.

Objective:To investigate the regulatory effects of transcutaneous auricular vagus nerve stimulation (taVNS) on functional connectivity (FC) of thalamic subregions in patients with premenstrual syndrome (PMS).Methods:This study was a cross-sectional investigation. Clinical, laboratory, and imaging data were retrospectively collected from 56 PMS patients (PMS group) and 66 healthy controls (control group) recruited from various universities and hospitals in Nanning between November 2021 and June 2024. Resting-state functional MRI (fMRI) data and fMRI data during taVNS immediate stimulation (2 Hz, 25 Hz) were acquired from subjects during their late luteal phase. Using thalamic subregions (anterior thalamic nucleus, lateral nucleus, ventral nucleus, medial nucleus, central nucleus, posterior nucleus) as seeds, two-sample t-tests or paired t-tests were employed to analyze alterations in thalamic subregion FC in PMS patients and the regulatory effects of taVNS on these changes. Independent samples t-test were used to compare the differences in clinical and laboratory indicators between the PMS group and the control group. The relationship between taVNS regulation of thalamic subregion FC in PMS patients and thalamic internal functional connectivity were analyzed using mediation effect analysis. Results:Compared to the control group, patients in the PMS group showed increased scores on the Daily Record of Severity of Problems, Pittsburgh Sleep Quality Index, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Hamilton Anxiety Rating Scale 17, and Hamilton Depression Rating Scale 14 during the late luteal phase ( P<0.05). At baseline, PMS patients exhibited higher FC between the left thalamic lateral nucleus and the left insula, and lower FC between the left medial nucleus, posterior nucleus, and ventral nucleus of the thalamus and the right middle frontal gyrus (MFG) compared to the control group (GRF corrected, voxel-level P<0.001, cluster-level P<0.05). During 2 Hz taVNS immediate stimulation in PMS group, FC between the left thalamic medial nucleus, posterior nucleus, ventral nucleus and the right MFG, as well as the FC between the left thalamic ventral nucleu and the left MFG increased compared to baseline levels; meanwhile, FC between the left thalamic posterior nucleus, ventral nucleus and the left insula decreased compared to baseline levels (GRF corrected, voxel-level P<0.001, cluster-level P<0.05). During 25 Hz taVNS immediate stimulation, the FC between the left thalamic ventral nucleus and the right MFG decreased compared to the baseline level (GRF corrected, voxel-level P<0.001, cluster-level P<0.05). Mediation effect analysis showed that the FC between the left thalamic posterior nucleus and the left lateral nucleus mediated part of the association between the FC of the left lateral thalamic nucleus-left insula and the FC of the left ventral thalamic nucleus-left putamen/insula; there were significant direct effects between the FC of the left lateral thalamic nucleus-the left posterior nucleus and FC of the left lateral thalamic nucleus-the left insula, as well as between the FC of the left ventral thalamic nucleus-the left MFG and FC of the left ventral thalamic nucleus-the right MFG. Conclusions:taVNS can modulate abnormal FC of the left thalamic subregions in PMS patients, restoring it toward normalization. The regulatory effects of 2 Hz stimulation are more pronounced than those of 25 Hz stimulation. This modulation primarily operates through two pathways: the left thalamic lateral nucleus-left insula-left thalamic ventral nucleus pathway and the left MFG-left thalamic ventral nucleus-right MFG.

Objective To explore the impact of organizational innovation climate in public hospitals on doctors'innovation performance,providing a reference for improving doctors'innovation performance.Methods A questionnaire survey was conducted with practicing(assistant)physicians in 22 hospitals in Beijing,and 1 859 questionnaires were effectively recovered.The scores of hospital organizational innovation climate,physicians'individual innovation performance,innovation behavior,and innovation self-efficacy were analyzed by Pearson correlation;the partial least squares structural equation modeling was further used to explore the role of the organizational innovation climate of hospitals on physicians'innovation performance.Results The path of hospital organizational innovation climate on physicians'innovation performance.The difference in path coefficients for the mediating effect of hospital organizational innovation climate significantly affecting physicians'innovation performance,and physicians'innovation self-efficacy between hospital innovation climate and physicians'innovation behavior and innovation performance was statistically significant(P＜0.001).Conclusion The innovation performance of practicing(assistant)physicians in Beijing municipal hospitals is influenced by the organizational innovation climate,physicians'innovation self-efficacy and innovation behaviors,and physicians'innovation self-efficacy and innovation behaviors play a chain-mediated role.It is suggested that public hospitals should strengthen doctors'self-efficacy and consider the fit between the construction of innovation atmosphere and actual needs to stimulate innovation behavior and ultimately improve inno-vation performance.

The prevalence of cardiovascular diseases among children and adolescents continues to escalate, with cardiometabolic risk factors emerging as primary contributors to this concerning trend. Key contributing factors encompass obesity, diabetes mellitus, and hypertension. This developmental phase represents a crucial window for both physical maturation and psychological growth. Previous studies have demonstrated significant associations between cardiovascular pathologies and mental health outcomes. Given their immature physiological and psychological regulatory systems, children and adolescents exhibit heightened susceptibility to emotional dysregulation, predominantly manifesting as anxiety disorders and depressive conditions.Current research remains limited in elucidating the complex relationship between cardiometabolic risk profiles and affective disorders within this vulnerable population. Emerging evidence suggests that cardiometabolic disturbances may potentiate the pathogenesis and progression of mood disorders through multifaceted mechanisms including oxidative stress pathways, neuroendocrine system dysregulation, and maladaptive lifestyle patterns. However, substantial gaps persist in our understanding of the precise pathophysiological interactions underlying this association.This comprehensive review systematically examines the interconnection between cardiometabolic risk parameters and emotional disorders in pediatric populations. This article critically evaluate current assessment methodologies, epidemiological patterns, and clinical correlations while proposing mechanistic frameworks that integrate biochemical, neurological, and behavioral pathways. The analysis emphasizes the need for interdisciplinary approaches to address this pressing public health challenge.

Objective To investigate the influencing factors for low anterior resection syndrome(LARS)at one year after ileostomy reversal in patients who have undergone radical resection for rectal cancer,and to inform clinical interventions.Methods A retrospective cohort study was conducted on 312 patients who successfully underwent ileostomy reversal after radical resection for rectal cancer between January 2023 and January 2024 at 3 tertiary hospitals in Chongqing.Based on LARS scores at 1-year after stoma reversal,they were divided into a LARS group(score≥21)and a non-LARS group(score≤20).Clinical data were collected from the medical record system,including age,body mass index(BMI),sex,tumor size,tumor distance from the anal verge,T stage,N stage,date of low anterior resection,neoadjuvant therapy,postoperative chemotherapy,anastomotic leakage,and date of ileostomy reversal.Univariate analysis was used to screen potential influencing factors,and variables with P<0.2 were included in a multivariate logistic regression model.Binary stepwise regression analysis was applied to further analyze significant influencing factors for LARS at 1 year after ileostomy reversal.Results In the cohort,there were 127 patients assigned into the LARS group and 185 into the non-LARS group.The incidence of LARS at 1 year after ileostomy reversal was 40.70%,with mild cases accounting for 21.79%and severe ones for 18.91%,and a mean LARS score of 14.52±11.64.Multivariate logistic regression analysis showed that neoadjuvant therapy(yes vs no:OR=1.830,95%CI:1.088～3.089;P=0.023),tumor distance from anal verge≤5 cm(vs>5 cm:OR=2.044,95%CI:1.249～3.374;P=0.005),occurrence of anastomotic leakage(yes vs no:OR=7.470,95%CI:2.247～34.102;P=0.003),time to reversal(≥181 d vs 91～180 d:OR=2.297,95%CI:1.363～3.917;P=0.002),and N stage(N1～N2 vs N0:OR=1.650,95%CI:1.009～2.717;P=0.047)were significant influencing factors for LARS at 1 year after ileostomy reversal.Conclusion Our results suggest that anastomotic leakage,time to reversal≥181 d,tumor distance from anal verge≤5 cm,neoadjuvant therapy,and N stage N1～N2 are associated with the occurrence of LARS at 1 year after ileostomy reversal in patients following radical resection of rectal cancer.Clinical healthcare providers should implement early intervention and long-term follow-up for patients with high-risk factors both before and after stoma reversal.

Objective To investigate the predictive value of pulmonary artery(Pa)to aortic(Ao)diameter ratio(Pa/Ao)for long-term major adverse cardiovascular events(MACEs)in patients with acute decompensated heart failure(ADHF).Methods ADHF patients hospitalized in the Department of Cardiology of Nanjing Drum Tower Hospital from January 2018 to January 2023 were consecutively enrolled.The data of gender,age,past medical history,laboratory examination,echocardiography,chest CT and medication were collected.The diameters of Pa and Ao were measured at the bifurcation of main pulmonary artery on chest CT,and Pa/Ao was calculated.The Kaplan-Meier method was used for survival analysis,and the Log-rank test was used to compare the survival rate between the two groups.Cox proportional hazards regression model was used to analyze the association between Pa/Ao and MACEs,and subgroup analysis was performed according to different age,sex,BMI,B-type natriuretic peptide level,and left ventricular ejection fraction.Results A total of 600 ADHF patients were enrolled,with an average age of 69.6 years and 347(57.8%)males.During a median follow-up of 306(127,624)days,327(54.5%)patients experienced MACEs.The ADHF patients were divided into Pa/Ao<0.93 group and Pa/Ao≥0.93 group according to the analysis of maximum selection rank statistics.Kaplan-Meier curve showed that the incidence of MACEs in Pa/Ao≥0.93 group was significantly higher than that in Pa/Ao<0.93 group(PLog-rank<0.001).Multivariate Cox regression analysis showed that Pa/Ao was an independent predictor of MACEs in ADHF patients(HR=11.62,95%CI:4.91～27.50,P<0.001).Subgroup analysis showed that Pa/Ao had predictive value for different ADHF populations(all P<0.05).Conclusion Elevated Pa/Ao is a predictor of long-term MACEs in ADHF patients.

Objective To explore the correlation between body fat estimation formula of Navarra University(CUN-BAE)and bone mineral density(BMD)in patients with type 2 diabetes mellitus(T2DM)and its predictive value for osteoporosis(OP).Methods A total of 428 patients with T2DM who were hospitalized in the Department of Endocrinology and Metabolism,Affiliated Hospital of Jiangsu University were enrolled in this study between October 2017 and October 2023.All the patients were divided into simple T2DM group(n=226),osteopenia(OT,n=126)group and OP group(n=76)according to BMD.The general data and biochemical indexes were compared between the two groups.The value of CUN-BAE was calculated,and the BMD value was testedby dual-energy X-ray method.The correlation between CUN-BAE and other indexes was evaluated by Spearman correlation,and the influencing factors for OP was evaluated by Logistic regression in T2DM patients.The diagnostic efficacy of CUN-BAE was explored by receiver operating characteristic(ROC)curve in T2DM patients complicated with OP.Results CUN-BAE was higher in OP group than in T2DM and OT group(P<0.05).Spearman correlation analysis showed that CUN-BAE was negatively correlated with the values of L1,L2,L3,L4,L1～L4,L2～L4,femoral neck BMD,wards triangle BMD,greater trochanter BMD,total hip BMD and L1～L4 BMD T value(P<0.05).Logistic regression analysis showed that CUN-BAE was a influencing factor for OP in T2DM patients.ROC curve analysis showed that the area under the curve predicted by CUN-BAE for T2DM patients complicated with OP was 0.672.Conclusions CUN-BAE value were significantly elevated in T2DM patients with OP.CUN-BAE was valuable for predicting OP in T2DM patients.
