Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex disease that is often accompanied by mental health disorders. However, the potential mechanisms underlying the heterogeneous clinical presentation of CP/CPPS remain uncertain. This study analyzed widely targeted metabolomic data of expressed prostatic secretions (EPS) and plasma to reveal the underlying pathological mechanisms of CP/CPPS. A total of 24 CP/CPPS patients from The Second Nanning People's Hospital (Nanning, China), and 35 asymptomatic control individuals from First Affiliated Hospital of Guangxi Medical University (Nanning, China) were enrolled. The indicators related to CP/CPPS and psychiatric symptoms were recorded. Differential analysis, coexpression network analysis, and correlation analysis were performed to identify metabolites that were specifically altered in patients and associated with various phenotypes of CP/CPPS. The crucial links between EPS and plasma were further investigated. The metabolomic data of EPS from CP/CPPS patients were significantly different from those from control individuals. Pathway analysis revealed dysregulation of amino acid metabolism, lipid metabolism, and the citrate cycle in EPS. The tryptophan metabolic pathway was found to be the most significantly altered pathway associated with distinct CP/CPPS phenotypes. Moreover, the dysregulation of tryptophan and tyrosine metabolism and elevation of oxidative stress-related metabolites in plasma were found to effectively elucidate the development of depression in CP/CPPS. Overall, metabolomic alterations in the EPS and plasma of patients were primarily associated with oxidative damage, energy metabolism abnormalities, neurological impairment, and immune dysregulation. These alterations may be associated with chronic pain, voiding symptoms, reduced fertility, and depression in CP/CPPS. This study provides a local-global perspective for understanding the pathological mechanisms of CP/CPPS and offers potential diagnostic and therapeutic targets.

Objective:To explore the feasibility of the multiple-choice auditory graphical interactive check（MAGIC） screening module in childhood hearing screening in children aged 3 to 6 years. Methods:A hearing screening was conducted on 366 children（732 ears） aged between 3 and 6 years. The screening methods included MAGIC, DPOAE, and acoustic immittance.The cooperation, screening time, pass rate, and correlation of the three screening methods were compared. Results:There was a statistically significant difference in the degree of cooperation among the three screeningmethods（P=0.004）.The MAGIC pure tone screening method was 98.6%, the screening DPOAE was 99.5%,and the acoustic immittance screening was 100%. For the screening duration, the MAGIC pure tone screening method was（116.3±59.1）s, the screening DPOAE was（27.2±19.7）s, and the acoustic impedance screening was（24.6±14.6）s. There was a significant statistical significance differences among the three or two groups（P<0.01）. The passing rates of MAGIC pure tone screening,screening DPOAE and acoustic immittance screening were 64.7%, 65.4%, and 69.3%, respectively, and there was no significant statistical difference among the three or two groups（P>0.05）. There was no significant difference between MAGIC pure tone screening method and screening DPOAE（P=0.827>0.05）, and acoustic impedance（P=0.653>0.05）, while the difference between screening DPOAE and acoustic impedance was statistically significant（P<0.01）. Conclusion:MAGIC pure sound screening method has good feasibility, can comprehensively reflect the hearing level of screened children, and can be promoted for hearing screening in children aged between 3 and 6 years.

Environmental toxicants have been linked to aging and age-related diseases. The emerging evidence has shown that the enhancement of detoxification gene expression is a common transcriptome marker of long-lived mice, Drosophila melanogaster, and Caenorhabditis elegans. Meanwhile, the resistance to toxicants was increased in long-lived animals. Here, we show that farnesoid X receptor (FXR) agonist obeticholic acid (OCA), a marketed drug for the treatment of cholestasis, may extend the lifespan and healthspan both in C. elegans and chemical-induced early senescent mice. Furthermore, OCA increased the resistance of worms to toxicants and activated the expression of detoxification genes in both mice and C. elegans. The longevity effects of OCA were attenuated in Fxr ^-/- mice and Fxr homologous nhr-8 and daf-12 mutant C. elegans. In addition, metabolome analysis revealed that OCA increased the endogenous agonist levels of the pregnane X receptor (PXR), a major nuclear receptor for detoxification regulation, in the liver of mice. Together, our findings suggest that OCA has the potential to lengthen lifespan and healthspan by activating nuclear receptor-mediated detoxification functions, thus, targeting FXR may offer to promote longevity.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective To observe the clinical effect of hysteroscopic combined with laparoscopic repair and reconstruction of diverticulum in the treatment of post-cesarean section uterine diverticulum(PCSD).Methods A total of 150 patients with PCSD admitted to the department of gynaecology of our hospital from January 2020 to February 2022 were selected and divided into the transvaginal group(transvaginal repair of diverticulum)and the combined group(hysteroscopic combined with laparoscopic repair and reconstruction of diverticulum)according to different surgical plans,with 75 cases in each group.The general condition of surgery,days of menstrual period,thickness of muscular layer,inflammation-related factor levels,complications and pregnancy in patients with birth plan were recorded in both groups.Results The operation time of patients in the combined group was longer than that in the transvaginal group,and the time of anal exhaustion and postoperative hospital stay of patients in the combined group were shorter than those in the transvaginal group,the differences were statistically significant(P<0.05);There was no significant difference in terms of the intraoperative bleeding volume of patients between the two groups(P>0.05).The high-sensitivity C-reactive protein(hs-CRP),interleukin-4(IL-4),interleukin-8(IL-8),and tumor necrosis factor-α(TNF-α)7 days after surgery of patients were lower in both groups compared with those before surgery,and the combined group was lower than the transvaginal group,the differences were statistically significant(P<0.05).Compared with that before the surgery,the days of menstrual period of patietns in both groups 6 and 12 months after the surgery decreased,and the thickness of muscular layer increased,with statistically significant differences(P<0.05);while no statistically significant difference was found in terms of the days of menstrual period or thickness of muscular layer of patients 6 and 12 months after surgery between the two groups(P>0.05).There was no significant difference in the incidence of cumulative complications such as incision infection,hyponatraemia,bladder injury and vaginal infection between the two groups(P>0.05).The intrauterine pregnancy rate of patients with birth plan and the full-term pregnancy rate in the combined group were higher than those in the transvaginal group,the differences were statistically significant(P<0.05).There was no statistically significant difference in the abortion rate or preterm birth rate between the two groups(P>0.05).Conclusion The hysteroscopic combined with laparoscopic repair and reconstruction of diverticulum for patients with PCSD has a fast postoperative recovery,a short hospital stay,and can increase the pregnancy rate of patients with birth plan.

Objective:To establish and evaluate a second-tier screening method for neonatal congenital adrenal hyperplasia (CAH) and develop appropriate screening interpretation criteria.Methods:We employed liquid chromatography-tandem mass spectrometry to simultaneously detect five steroid hormones in dried blood spots: 17α-hydroxyprogesterone (17α-OHP), androstenedione (A4), 11-deoxycortisol (11-DOC), 21-deoxycortisol (21-DOC), and cortisol (F), calculating (17α-OHP+A4)/F and (17α-OHP+21-DOC)/F ratios for second-tier CAH screening. The study utilized 429 residual dried blood spot samples from neonates (0-7 days) who completed first-tier screening between January 2020 and March 2024 in Guangzhou Women and Children's Medical Center, Guangzhou Medical University, including first-tier negatives ( n=369), confirmed false positives ( n=50), and CYP21A2-confirmed 21-hydroxylase deficiency patients ( n=10). Mann-Whitney U and Kruskal-Wallis tests analyzed steroid concentration variations across gestational ages and birth weights in all negative samples, with reference intervals established via P2.5- P97.5 percentiles and screening cutoffs set at population P97.5. Receiver operating characteristic (ROC) curve analysis identified optimal interpretation indicators among steroid hormone profiles, with second-tier screening performance evaluated by comparing sensitivity and specificity across different steroid hormone indicators to establish the optimal diagnostic criteria. Results:The five steroid hormones demonstrated intra-assay precision with coefficient of variation (CV) of 9.8%-14.2% and inter-assay precision with CV of 4.7%-14.4% across three different concentration levels of quality control materials. Accuracy ranged from 98.5% to 110.0% and the lower limits of quantification were 0.25 ng/ml for 17α-OHP, 0.05 ng/ml for A4/11-DOC, 0.31 ng/ml for 21-DOC, and 0.1 ng/ml for F. Stratification by gestational age categorized 17α-OHP into ≤31, 32-34, and ≥35 weeks; A4 into ≤31, 32-36, and ≥37 weeks; and 11-DOC into ≤31 and ≥32 weeks, while the remaining indicators were not stratified. When grouped by birth weight (low/normal), all measured parameters except 21-DOC showed statistically significant differences between groups (all P<0.05). Established reference intervals included 17α-OHP: 0.53-7.82 ng/ml (≤31 weeks), <0.25-3.60 ng/ml (32-34 weeks), <0.25-1.64 ng/ml (≥35 weeks); A4: 0.12-2.36 ng/ml (≤31 weeks), <0.05-1.45 ng/ml (32-36 weeks), 0.17-0.95 ng/ml (≥37 weeks); 11-DOC: 0.43-4.04 ng/ml (≤31 weeks), 0.08-1.46 ng/ml (≥32 weeks); F: 1.70-83.70 ng/ml; 21-DOC: <0.31-0.69 ng/ml; (17α-OHP+A4)/F: 0.01-0.74; and (17α-OHP+21-DOC)/F: 0.01-0.69. Comprehensive comparison of CAH second-tier screening performance demonstrated that interpretation based on elevated 17α-OHP accompanied by either elevated 21-DOC or elevated ratios [(17α-OHP+A4)/F or (17α-OHP+21-DOC)/F] achieved 100% sensitivity, 96% specificity, and a 96% reduction in false-positive rate. Conclusion:The application of liquid chromatography-tandem mass spectrometry for multi-steroid hormone profiling in second-tier neonatal CAH screening, utilizing gestational age-specific 17α-OHP cutoffs combined with elevated 21-DOC or ratio criteria, demonstrated 100% screening sensitivity while substantially reducing false-positive rates from primary screening, though further validation with expanded sample sizes remains necessary.

Purpose: Zinc finger protein 639 (ZNF639) is often found within the overlapping amplicon of PIK3CA, and previous studies suggest its involvement in the pathogenesis of esophageal and oral squamous cell carcinomas. However, its expression and significance in breast cancer remain uncharacterized. Methods: Immunohistochemical analysis of ZNF639 was performed using tissue microarrays.Functional studies, including colony formation, Transwell cell migration, and in vivo metastasis, were conducted on breast tumor cells with ZNF639 knockdown via small interfering RNA transfection. Results: Reduced ZNF639 immunoreactivity was observed in 82% of the breast cancer samples, independent of hormone receptor and human epidermal growth factor receptor 2 status. In multivariate Cox regression analyses, ZNF639 expression was associated with favorable survival outcomes, including recurrence-free survival (hazard ratio, 0.35; 95% confidence interval [CI], 0.14–0.89) and overall survival (hazard ratio, 0.41; 95% CI, 0.16– 1.05). ZNF639 knockdown increased clonogenicity, cell motility, and lung metastasis in NOD/ SCID mice. Following the ZNF639 knockdown, the expression of Snail1, vimentin, and C-C chemokine ligand 20 (CCL20) was upregulated, and the changes in cell phenotype mediated by ZNF639 were reversed by the subsequent knockdown of CCL20. Conclusion Low ZNF639 expression is a novel prognostic factor for recurrence-free survival in patients with breast cancer.
