BackgroundAdolescents with depressive disorder often engage in non-suicidal self-injury (NSSI) behaviors, which severely impacts their physical and mental health. Impulsivity and emotional regulation are key factors influencing NSSI behaviors. However, research on the mechanisms through which impulsivity and emotional regulation affect NSSI behaviors in adolescent depressive disorder patients with NSSI remains insufficient, limiting the development of effective intervention strategies. ObjectiveTo explore the differences in impulsivity and emotion regulation abilities between adolescent patients with depressive disorder accompanied by and without NSSI behaviors, and to analyze the association between NSSI behaviors and impulsivity and emotion regulation abilities in adolescent patients with depressive disorder accompanied by NSSI behaviors. MethodsA total of 184 adolescents hospitalized in the child and adolescent psychiatry department of Wuxi Mental Health Center from October 2023 to August 2024, who met the diagnostic criteria for depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), were consecutively enrolled as study subjects. Based on the diagnostic criteria for NSSI in DSM-5, patients were divided into NSSI group (n=108) and non-NSSI group (n=76). The Barratt Impulsiveness Scale-11 (BIS-11), the Emotion Regulation Questionnaire (ERQ), the Adolescent Self-Harm Questionnaire, and the Positive and Negative Suicide Ideation (PANSI) were used for assessment. Spearman correlation analysis was employed to explore the correlation between the scores of the Adolescent Self-Harm Questionnaire and the scores of BIS-11 and ERQ in the NSSI group. Multiple regression analysis was conducted to examine the effects of impulsivity and emotion regulation on NSSI behaviors in the NSSI group. ResultsCompared to the non-NSSI group, the NSSI group showed significantly higher scores in BIS-11 non-planned impulsivity (Z=-4.181, P<0.05), action impulsivity (t=4.944, P<0.05), cognitive impulsivity (Z=-3.392, P<0.05), and total score (t=4.763, P<0.05), and lower scores in the cognitive reappraisal of ERQ (t=-4.094, P<0.05) and total score (Z=-2.299, P<0.05), and higher scores in the expression inhibition of ERQ (Z=-3.019, P<0.05). The correlation analysis results showed that the score of the adolescent self-harm questionnaire in the NSSI group was positively correlated with the behavioral impulsivity factor score in the BIS-11 (r=0.434, P<0.05). Multiple regression analysis indicated that action impulsivity factor was a significant correlate of self-injury behaviors in the NSSI group (B=0.855, P<0.05), explaining 22.30% of the total variance. ConclusionAdolescent patients with depressive disorder accompanied by NSSI behaviors exhibit higher levels of impulsivity and poorer emotional regulation abilities. Action impulsivity may play a significant role in the mechanism of NSSI behaviors. [Funded by Wuxi Municipal Health Commission Research Project (number, Q202320)]

ObjectiveIn traditional Chinese medicine (TCM), the foundational doctrine that the eyes reflect the essence of the internal viscera establishes ocular observation as a cornerstone of diagnostic practice. Specifically, the morphological characteristics and coloration variations of the scleral microvasculature serve as critical clinical indicators for assessing the dynamic balance of Qi and Blood, as well as the pathological status of internal organs. Historically, however, TCM eye diagnosis has relied predominantly on the subjective clinical experience and visual acuity of individual practitioners, leading to inherent challenges in standardization and reproducibility. While automated computer-aided diagnostic systems offer a promising solution, existing vessel segmentation algorithms encounter significant domain-specific bottlenecks when applied to scleral imagery. These challenges primarily stem from the highly reflective and moist nature of the ocular surface, which generates severe reflective interference. Furthermore, the inherent low contrast of fine capillary networks against complex background textures, compounded by non-uniform illumination, frequently results in high false-positive rates, misdetections, and severe vessel fragmentation. To address these critical limitations and advance the objective quantification of TCM diagnostics, this paper proposes a novel, highly robust sclera vessel segmentation framework that innovatively integrates Frangi-Sato dual-filter adaptive enhancement with pixel-level reflection detection. MethodsThe proposed methodology systematically addresses the segmentation pipeline through three synergistic stages. First, to overcome the structural limitations of single-filter approaches, a multi-scale weighted fusion strategy is meticulously designed to harness the complementary extraction capabilities of both Frangi and Sato filters. This adaptive enhancement optimally balances the preservation of main vessel trunk continuity with the heightened sensitivity required for delineating delicate, low-contrast peripheral capillaries. Second, to tackle the persistent issue of reflective highlights, a sophisticated multi-feature synergistic reflection detection module is introduced. By jointly analyzing local information entropy, gradient field variations, and intensity statistical distributions, this module achieves precise, pixel-level identification and elimination of reflective artifacts without compromising the underlying vascular structures. Finally, a dual-level adaptive thresholding strategy, featuring an innovative “core protection” mechanism, is implemented. This critical step effectively suppresses complex background noise while rigorously preserving the structural and topological integrity of the intricate vessel network, preventing the structural breaks often seen in conventional binarization methods. ResultsThe efficacy of the proposed framework was rigorously evaluated using both self-constructed clinical datasets specifically acquired for TCM research and standardized public datasets. Extensive experimental results demonstrate that the proposed method consistently outperforms state-of-the-art traditional approaches and contemporary deep learning models. Specifically, the proposed method achieves a Dice similarity coefficient of approximately 0.71 on the private clinical dataset, and secures the best performance across the majority of quantitative metrics on both datasets. Notably, the framework exhibits exceptional robustness and generalization capabilities in highly challenging scenarios characterized by intense reflective interference, low signal-to-noise ratios, and cross-domain image variations. ConclusionThis study successfully realizes the high-integrity, automated segmentation of scleral vessel networks under complex clinical imaging conditions. By overcoming the fundamental algorithmic challenges of reflection interference and micro-vessel loss, the proposed methodology provides potential support for the digitization, objective standardization, and intelligent advancement of modern TCM eye diagnosis systems.

ObjectiveTo investigate the mechanism of Yijing decoction to inhibit oxidative stress induced by chronic iron overload and improve ovarian reserve hypofunction in mice. MethodsSeventy-two female C57BL/6J mice with normal estrous cycles were randomly divided into six groups (n=12 per group):blank group,model group,Yijing decoction(YJD) low-dose group,medium-dose group,high-dose group,and dehydroepiandrosterone (DHEA) group. Mice in the blank group received intraperitoneal injections of normal saline,while those in all other groups were administered iron dextran (Sigma-Aldrich) at a dose of 0.5 g·kg-1 once weekly for 8 weeks to establish a chronic iron overload model. Following the final injection,interventions were initiated and continued for 4 weeks. The low,medium,and high dose groups of YJD received oral gavage of Yijing decoction aqueous solution at doses of 18.165, 36.33,and 72.66 g·kg-1·d-1,respectively. The DHEA group received DHEA aqueous solution at 10.812 5 mg·kg-1·d-1. The blank and model groups received an equivalent volume of distilled water by gavage once daily. Body weight was recorded weekly,and food intake was monitored throughout the treatment period. Vaginal smears were collected daily and stained with hematoxylin-eosin (HE) to assess estrous cycle regularity. At the end of the experiment,mice were euthanized,and bilateral ovaries and uteri were rapidly excised and weighed to calculate ovarian and uterine indices (mg·g-1). Ovarian tissues were fixed,embedded,and sectioned for hematoxylin and eosin (HE) staining to evaluate histopathological changes. Iron deposition in ovarian tissue was visualized using Prussian blue staining. Serum levels of follicle-stimulating hormone (FSH),luteinizing hormone (LH),estradiol (E2),and anti-Müllerian hormone (AMH) were measured by enzyme-linked immunosorbent assay (ELISA). Malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in ovarian homogenates were determined using commercial biochemical assay kits. Reactive oxygen species (ROS) levels in ovarian tissue were assessed by ROS fluorescence staining on frozen sections. Mitochondrial ultrastructure in ovarian tissue was examined by transmission electron microscopy (TEM). Total RNA was extracted from ovarian tissue for real-time quantitative polymerase chain reaction (Real-time PCR) to quantify mRNA expression of ferritin heavy chain 1 (Fth1),ferritin light chain (Ftl),transferrin (Tf),transferrin receptor 1 (Tfr1),catalase (Cat),and glutathione peroxidase 1 (GPX1). Protein expression levels of Fth1,Ftl,Tf,Tfr1,and glutathione peroxidase 4 (GPX4) were analyzed by Western blot. ResultsCompared with the blank group,mice in the model group exhibited significantly reduced body weight and severe estrous cycle disruption (P<0.01),a markedly increased uterine index (P<0.01),and a significantly decreased ovarian index (P<0.01). The number of antral follicles was significantly reduced,while atretic follicles were markedly increased,accompanied by pronounced iron deposition in the ovarian stroma. Serum levels of AMH and E2,as well as ovarian SOD activity,protein and mRNA expression of Tf and Tfr1,and mRNA levels of GPX1 and Cat were all significantly downregulated (P<0.05,P<0.01). Conversely,serum FSH and LH levels,MDA content,protein and mRNA expression of Fth1 and Ftl,and ROS fluorescence intensity were significantly elevated (P<0.05,P<0.01),along with a marked decrease in GPX4 protein expression (P<0.01). TEM revealed an increased number of damaged mitochondria in ovarian tissue,characterized by loss or disappearance of mitochondrial cristae. Compared with the model group,treatment with low,medium,and high doses of YJD and DHEA significantly improved body weight and ameliorated estrous cycle irregularities (P<0.05,P<0.01),decreased the uterine index (P<0.05),and increased the ovarian index (P<0.05,P<0.01). These groups also showed increased numbers of antral follicles,reduced atretic follicles,and significantly diminished iron deposition in the ovarian stroma. Serum AMH and E2 levels,ovarian SOD activity,protein and mRNA expression of Tf and Tfr1,and mRNA levels of GPX1 and Cat were all significantly upregulated (P<0.05,P<0.01). In contrast,serum FSH and LH levels,MDA content,protein and mRNA expression of Fth1 and Ftl,and ROS fluorescence intensity were significantly reduced (P<0.05,P<0.01),while GPX4 protein expression was markedly increased (P<0.01). Moreover,mitochondrial damage was alleviated,and mitochondrial ultrastructure was notably restored in ovarian tissue. ConclusionYijing decoction ameliorates ovarian reserve function in mice with chronic iron overload by upregulating the expression of Tf,Tfr1,and GPX4,downregulating the expression of Ft,Fth1,and Ftl,thereby alleviating systemic iron metabolism disorders,reducing oxidative stress in ovarian tissue,and restoring mitochondrial morphology and structure.

ObjectiveTo investigate the incidence, glucolipid metabolism characteristics, and associated factors of postoperative overweight/obesity in children and adolescent with craniopharyngioma. MethodsA retrospective study was conducted using follow-up data from 44 patients (aged 0-18 years) diagnosed with craniopharyngioma who underwent surgical treatment and received follow-up care at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, between January 2006 and February 2024. The incidence and glucolipid metabolism characteristics of overweight/obesity were summarized, and potential influencing factors were analyzed. ResultsA total of 44 patients were enrolled. The mean age at surgery was (8.57 ± 4.25) years, and the mean age at last follow-up was (16.02 ± 5.36 )years. The mean follow-up duration was (7.45 ± 4.64) years (range, 8 months to 17.5 years). The preoperative incidence of overweight/obesity was 40.91% (predominantly overweight, 27.27%), which increased to 68.18% postoperatively (predominantly obesity, 50.00%). Postoperatively, all patients (44/44, 100%) underwent fasting plasma glucose (FPG) testing, among whom 2 (4.55%) had impaired fasting glucose (IFG). Fasting insulin (FINS) was measured in 20 patients, and insulin resistance was identified in 11 (55.00%). Oral glucose tolerance testing (OGTT) with insulin release assessment was performed in 12 patients, and all (100%) exhibited abnormal insulin secretion, including 5 (41.67%) with hyperinsulinemia and 3 (25.00%) diagnosed with diabetes mellitus (DM). All patients (44/44, 100%) underwent lipid profile assessment. The incidence of dyslipidemia was 81.82% (36/44), including elevated non-high-density lipoprotein cholesterol (29/44, 65.91%), hypertriglyceridemia (29/44, 65.91%), low high-density lipoprotein cholesterol (22/44, 50.00%), and mixed hyperlipidemia (13/44, 29.55%). Logistic regression analysis indicated that preoperative overweight/obesity and postoperative abnormal glucose metabolism were significant factors associated with postoperative overweight/obesity. Compared with normal-weight patients, those with postoperative overweight/obesity had higher FINS levels (14.22 mU/L vs. 3.57 mU/L), higher insulin resistance index(HOMA-IR) (2.88 vs. 0.52), and a higher incidence of abnormal glucose metabolism (77.78% vs. 23.08%). However, no significant difference was observed in the incidence of dyslipidemia (94.44% vs. 73.08%). ConclusionsChildren and adolescent with craniopharyngioma exhibit a higher incidence of overweight/obesity than healthy peers preoperatively, which becomes more pronounced after surgery. This is accompanied by a high incidence of glucolipid metabolic disorders, placing these patients at increased risk of metabolic syndrome, which warrants clinical attention and regular metabolic assessment. In patients who develop postoperative obesity, particular attention should be given to the risk of glucose metabolism abnormalities, and further monitoring of glucose homeostasis is recommended.

The next morning, the vaginal plug was found or the sperm was seen under the microscope as the successful modeling, which was counted as the first day of pregnancy. CBA/J×BALB/c mice were set as normal group, and the RSA model pregnant mice were divided into model group, progesterone group, and Bushen Antai Mixture low-, medium-, and high-dosage groups using a random number table method, with 6 mice in each group. The normal group and the model group were given distilled water by gavage. Bushen Antai Mixture low-, medium-, and high-dosage groups were given 3.9 g/kg, 11.7 g/kg and 23.4 g/kg Bushen Antai Mixture by gavage. The progesterone group was given progesterone capsule aqueous solution 26 mg/kg by gavage for 14 consecutive days. The embryo loss rate of mice was calculated. The pathological changes of placental tissues were observed by HE staining. The expressions of Nrf2, HO-1 and NF-κB protein and mRNA in placental tissues were detected by Western blot and RT-qPCR.Results:Compared with the model group, the embryo loss rate of mice in the Bushen Antai Mixture low-, medium-, and high-dosage groups and the progesterone group significantly decreased ( P<0.05, P<0.01); the pathological morphology of placental tissue improved; the expressions of Nrf2, HO-1 protein and mRNA in placental tissue significantly increased ( P<0.05, P<0.01), and the expression of NF-κB protein and mRNA significantly decreased ( P<0.05, P<0.01). Conclusion:Bushen Antai Mixture may may treat RSA by activating the Nrf2/HO-1 pathway, inhibiting NF - κB expression, and improving oxidative stress and inflammatory response in the placental tissue of RSA pregnant mice.
