ObjectiveThis study aims to explore the potential of different orders of magnitude single-nucleotide polymorphism (SNP) locus combinations for predicting distant kinship relationships. A high-density SNP locus set was constructed, and a comprehensive assessment of its inference capability was conducted. MethodsFirstly, we selected three commercial chip panels, CGA (Chinese genotyping array, Illumina), GSA (Global screening array, Illumina), Affy (23MF_V2 high-density SNP array, Affymetrix) and merged them after quality control, forming a high-density SNP locus panel(1 180 k). Secondly, we selected 161 samples and collected their peripheral blood samples by using whole-genome sequencing technology. Within this sample population, the levels of kinship relationships fully covered the range from level 1 to level 9, and the number of kinship pairs at each level was consistently maintained at over 50 pairs. From 161 samples data of whole-genome sequencing, the 1 180 k locus set was extracted, which is referred to as the high-density SNP locus set in the following text. The kinship inference was conducted using the identity-by-descent (IBD) algorithm with the selected optimal parameters. To comprehensively evaluate the performance of the high-density SNP locus set in kinship inference, we compared it with the three commercial chip panels, the intersection of these three chip loci, and the control sets constructed by randomly reducing the number of the high-density SNP locus set. Based on the changes in the IBD lengths, as well as the dynamic trends in prediction accuracy, we conducted a scientific assessment of the kinship inference capability of the high-density SNP locus set. ResultsAfter screening, a set of 1 184 334 autosomal SNPs was obtained. During the process of screening the optimal IBD length threshold, the result revealed that 0 cM, 1 cM, and 2 cM all demonstrated good applicability. However, to avoid the issue of a large amount of redundant information caused by setting a too low IBD length threshold, this study ultimately selected 2 cM as the optimal threshold. Compared with the average results of three chip panels, the high-density SNP locus set increased the total IBD length and the average IBD length across levels 1-9; the accuracy of the confidence interval for level 8 was 70.97%, which represented a 3.50% improvement; the average confidence interval accuracy for levels 1-8 was 91.39%, representing a 1.00% increase; and the false negative rates at levels 8 and 9 were reduced by 2.42% and 6.76%, respectively. The system efficacy of the high-density SNP locus set for kinship inference of first to eighth degree relationships reached 98.91%. Through random reduction of the high-density SNP locus set results, it is found that increasing the number of SNPs with the panel, the detection efficiency of IBD length showed a significant upward trend. At the same time, the overall trend in the accuracy of kinship relationship prediction as well as the confidence interval accuracy also indicated that both metrics steadily increased with the addition of more loci. ConclusionThe results show that the high-density SNPs panel significantly enhances the efficacy of distant kinship inference, accurately covering kinship degrees, with the average confidence interval accuracy for first to eighth degree relationships stably above 90%. The study finds that increasing the number of SNPs panel can improve the ability to predict distant kinship.

Aberrant activation of glycolysis represents a key metabolic mechanism underlying the initiation and progression of nasal inflammation. Allergic rhinitis, chronic rhinosinusitis, and vasomotor rhinitis exhibit distinct etiologies, yet all are characterized by inflammatory responses, impaired epithelial barrier function, and neurovascular dysregulation, in which glycolytic metabolic reprogramming acts as a central hub connecting immunometabolism and inflammatory regulation.Recent evidence indicates that glycolysis-dependent activation of immune cells provides the essential energy basis for inflammatory onset. In dendritic cells, eosinophils, mast cells, and Th2 cells, the expression of key glycolytic enzymes including HK2, PKM2, and LDHA is upregulated, thereby promoting cellular activation and proinflammatory cytokine release via the mTOR-HIF-1α signaling axis. Notably, the metabolic reprogramming of eosinophils prolongs their survival and enhances the release of cytotoxic granules, while in mast cells, enhanced glycolysis facilitates IgE-mediated degranulation and histamine release. Furthermore, glycolysis also influences the Th17/Treg balance, with enhanced glycolytic flux promoting Th17 differentiation and contributing to the heterogeneous inflammatory profiles observed across different rhinitis subtypes.As a central metabolite, lactate contributes to the formation of a metabolism-inflammation vicious cycle through multiple mechanisms. Lactate acidifies the local microenvironment to activate TRPV1 channels and facilitate neuropeptide release, mediates immune cell chemotaxis through GPR81, and regulates gene expression via histone lactylation, thereby sustaining proinflammatory gene transcription. These lactate-mediated processes collectively amplify local inflammation and contribute to the persistence of nasal symptoms.Glycolytic reprogramming in epithelial cells is modulated by the EGF/EGFR pathway, and its dysregulation may result in disrupted tight junctions, abnormal goblet cell hyperplasia, and subsequent tissue remodeling. Substance P and calcitonin gene-related peptide released from sensory neurons, in conjunction with metabolic products, synergistically maintain persistent inflammatory stimulation by activating mast cells, forming a neuro-immune-metabolic regulatory network that drives disease chronicity.From a therapeutic perspective, glycolytic inhibitors such as 2-deoxyglucose, FX11, and 3-bromopyruvate exert anti-inflammatory effects by targeting key enzymes including HK2 and LDHA, each with distinct mechanisms: 2-DG competitively inhibits hexokinase, FX11 selectively targets LDHA to reduce lactate production, and 3-BrPA modulates multiple glycolytic enzymes. Moreover, traditional Chinese medicine formulas, monomeric active components, and small-molecule compounds have shown promising potential in alleviating nasal inflammation by regulating the mTOR-HIF-1α axis, exerting antioxidant effects, and modulating endoplasmic reticulum stress pathways. The multi-target characteristics of these natural products offer advantages in addressing the complex pathophysiology of nasal inflammatory diseases.Despite these advances, several challenges remain. The non-selective inhibition of glycolysis may interfere with epithelial repair and mucosal regeneration, leading to delayed wound healing. Technical limitations in dynamic metabolic monitoring and sampling precision hinder the accurate assessment of local nasal metabolism. Furthermore, current animal models, which predominantly rely on acute stimulation protocols, inadequately recapitulate the chronic tissue remodeling processes characteristic of human rhinitis.This review systematically summarizes glycolysis as a common metabolic node shared by different rhinitis subtypes, offering a novel theoretical basis for the development of precision therapeutic strategies targeting metabolic reprogramming.

OBJECTIVE:
To investigate the therapeutic effect of the short-penis treatment apparatus and wide-band infrared therapy apparatus on penile dysplasia (PDP) in children and establish objective parameters for assessing the severity of PDP.
METHODS:
This study included 252 children received in the Department of pediatric urology of the First Affiliated Hospital of Xinjiang Medical University from January to December 2023, 102 with PDP (the PDP group) and the other 150 with normal penile development (the control group), those of the former group treated with the short-penis therapeutic apparatus and wide-band infrared therapy apparatus. Before and after 30 days of treatment, we measured the flaccid penile length (FPL), stretched penile length (SPL) and penile diameters (PD) of the children, and defined the penile dysplasia index as the FPL/SPL and FPL/PD ratios.
RESULTS:
The penile parameters exhibited statistically significant differences between the PDP and control groups, (FPL:[1.97±0.72]cm vs [3.25±0.51] cm, P<0.01; SPL:[3.80±0.81]cm vs [5.21±0.79]cm,P<0.01).The FPL remarkably increased in the PDP group after treatment([1.97±0.72]cm vs [2.90±1.20] cm, P<0.01). Both FPL and SPL were notably shorter in the PDP cases than in the controls, with the cutoff values of 0.57 and 2.09, sensitivities of 80.7% and 95.3%, and specificities of 69.6% and 82.4% for FPL/SPL and FPL/PD, respectively.
CONCLUSION
The short-penis therapeutic apparatus and wide-band infrared therapy apparatus can promote the growth and development of the penis in children. The ratio of FPL/PD can serve as an objective indicator to effectively describe the severity of penile developmental abnormalities.

BACKGROUND:
Recent studies have shown that sodium-glucose cotransporters-2 (SGLT2) inhibitors significantly improve major adverse cardiovascular events in heart failure with preserved ejection fraction (HFpEF) patients, but the exact mechanism is unknown. Ferritinophagy is a special form of selective autophagy that participates in ferroptosis. In this study, we aimed to investigate whether ferritinophagy was activated during the occurrence of HFpEF, and whether canagliflozin (CANA) could inhibite ferritinophagy.
METHODS:
We reared Dahl salt-sensitive (DSS) rats on a high-salt diet to construct a hypertensive HFpEF model, and simultaneously administered CANA intervention. Then we detected indicators related to ferritinophagy.
RESULTS:
The expression of nuclear receptor coactivator 4 (NCOA4), as well as microtubule-associated proteins light chain 3 (LC3), Bcl-2 interacting protein 1 (Beclin-1) and p62, were upregulated in HFpEF rats, accompanied by the downregulation of ferritin heavy chain 1 (FTH1), upregulation of mitochondrial iron transporter sideroflexin1 (SFXN1) and increased reactive oxygen species (ROS) production. Above changes were diminished by CANA.
CONCLUSION
Ferritinophagy is activated in HFpEF rats and then inhibited by CANA, leading to HFpEF benefits. The inhibition of ferritinophagy could provide new prospective targets for the prevention and treatment of HFpEF, and provide new ideas for investigating the mechanism of cardiovascular benefit of SGLT2 inhibitors.

Objective:To investigate the clinical efficacy of autologous costal cartilage rhinoplasty combined with costal cartilage block grafting to the alar base in the correction of saddle nose deformity with alar-columellar base depression.Methods:A retrospective analysis was performed on patients who underwent autologous costal cartilage rhinoplasty combined with alar base augmentation at the Department of Plastic Surgery, Zhejiang Provincial People’s Hospital, from January 2022 to December 2023. All patients presented with alar-columellar base depression combined with saddle nose deformity. Through bilateral marginal incisions of the lower lateral cartilage and an inverted V-shaped columellar incision, the 6th costal cartilage near the sternal end was harvested and sculpted into two alar base grafts, one columellar strut graft in an inverted V shape, two septal extension grafts, and one cap graft. On the basis of block costal cartilage grafting to the alar base, a nasal tip support framework and septal extension graft were constructed, combined with implantation of an expanded polytetrafluoroethylene (ePTFE) prosthesis, to correct the aesthetic defects of saddle nose with alar-columellar base depression. Postoperative complications and recovery were recorded. Standardized pre- and 6-month postoperative photographs were analyzed using Adobe Photoshop and Image J to measure nasal base elevation, nasolabial angle, nasofrontal angle, nasal tip angle, nasal tip projection-to-length ratio, and columella-lobule angle. Patient satisfaction was evaluated preoperatively and at 6 months postoperatively using the visual analogue scale (VAS, 0-10 points; higher scores indicate greater satisfaction) and the rhinoplasty outcome evaluation (ROE) questionnaire (total score 0-24; higher scores indicate greater satisfaction). Paired t-tests were used for statistical analysis, with P<0.05 considered statistically significant. Results:A total of 48 patients were enrolled, including 3 males and 45 females, aged from 19 to 37 years (27.3±5.9 years). The postoperative follow-up period ranged from 6 to 12 months. No infections, hemorrhage, or other complications occurred. Swelling subsided substantially within 4-5 weeks postoperatively, and no significant nasal airway obstruction, sensory abnormalities, or olfactory disturbances were observed. Patients were satisfied with their postoperative appearance and outcomes. At 6 months postoperatively, the nasal base elevation was increased compared with preoperative measurements (6.08 ± 0.85) mm. Compared with preoperative values, significant improvements were observed at 6 months postoperatively in nasolabial angle (84.69° ± 4.24° vs. 96.81° ± 5.80°), nasofrontal angle (143.91° ± 3.91° vs. 136.24° ± 2.66°), nasal tip angle (84.13° ± 5.25° vs. 78.20° ± 5.40°), nasal tip projection-to-length ratio (0.45 ± 0.05 vs. 0.53 ± 0.07), columella-lobule angle (49.22° ± 5.29° vs. 44.25° ± 3.52°), VAS score (4.69 ± 0.90 vs. 8.45 ± 0.80), and ROE score (11.99 ± 1.47 vs. 21.50 ± 1.31) (all P<0.05). Conclusion:Autologous costal cartilage rhinoplasty combined with costal cartilage block grafting to the alar base can effectively correct saddle nose deformity with alar-columellar base depression, achieving comprehensive improvement in midfacial aesthetics.

OBJECTIVE:
Acupuncture therapies are known for their effectiveness in treating a variety of gastric diseases, although the mechanisms underlying these effects are not fully understood. This study tested the effectiveness of electroacupuncture (EA) at acupoints Zhongwan (RN12) and Weishu (BL21) for managing gastric motility disorder (GMD) and investigated the underlying mechanisms involved.
METHODS:
A GMD model was used to evaluate the impact of EA on various aspects of gastric function including the amplitude of gastric motility, electrogastrogram, food intake, and the rate of gastric emptying. Immunofluorescence techniques were used to explore the activation of spinal neurons by EA, specifically examining the presence of cholera toxin B subunit (CTB)-positive neurons and fibers emanating from acupoints RN12 and BL21. The stimulation of γ-aminobutyric acid (GABA)-ergic neurons in the spinal dorsal horn, the inhibition of sympathetic preganglionic neurons in the spinal lateral horn, and their collective effects on the activity of sympathetic nerves were examined.
RESULTS:
EA at RN12 and BL21 significantly improved gastric motility compromised by GMD. Notably, EA activated spinal neurons, with CTB-positive neurons and fibers from RN12 and BL21 being detectable in both the dorsal root ganglia and the spinal dorsal horn. Further analysis revealed that EA at these acupoints not only stimulated GABAergic neurons in the spinal dorsal horn but also suppressed sympathetic preganglionic neurons in the spinal lateral horn, effectively reducing excessive activity of sympathetic nerves triggered by GMD.
CONCLUSION
EA treatment at RN12 and BL21 effectively enhances gastric motility in a GMD model. The therapeutic efficacy of this approach is attributed to the activation of spinal neurons and the modulation of the spinal GABAergic-sympathetic pathway, providing a neurobiological foundation for the role of acupuncture in treating gastric disorders.

OBJECTIVE:
To explore the association between acupuncture during controlled ovarian hyperstimulation (COH) and the live birth rate (LBR) using different propensity score methods.
METHODS:
In this retrospective cohort study, eligible women who underwent a COH were divided into acupuncture and non-acupuncture groups. The primary outcome was LBR, as determined by propensity score matching (PSM). LBR was defined as the delivery of one or more living infants that reached a gestational age over 28 weeks after embryo transfer. The propensity score model encompassed 16 confounding variables. To validate the results, sensitivity analyses were conducted using three additional propensity score methods: propensity score adjustment, inverse probability weighting (IPW), and IPW with a "doubly robust" estimator.
RESULTS:
The primary cohort encompassed 9751 patients (1830 [18.76%] in the acupuncture group and 7921 [81.23%] in the non-acupuncture group). Following 1:1 PSM, a higher LBR was found in the acupuncture cohort (41.4% [755/1824] vs 36.4% [664/1824], with an odds ratio of 1.23 [95% confidence interval, 1.08-1.41]). Three additional propensity score methods produced essentially similar results. The risk of serious adverse events did not significantly differ between the two groups.
CONCLUSION
This retrospective study revealed an association between acupuncture and an increased LBR among patients undergoing COH, and that acupuncture is a safe and valuable treatment option.
