IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide and a major cause of chronic kidney disease and kidney failure. IgAN exhibits marked heterogeneity in clinical presentation, histopathology, and pathogenic mechanisms, contributing to variable treatment responses and prognosisamong patients. Precise risk assessment and individualized intervention are therefore of critical importance. This review systematically traces the evolution of IgAN management from traditional risk stratification toward biomarker-driven precision medicine. We first review the clinical utility and limitations of established risk stratification tools, including the KDIGO guidelines, the Oxford MEST-C classification, and the International IgAN Prediction Tool. We then discuss emerging biomarkers closely linked to disease pathogenesis, including galactose-deficient IgA1 (Gd-IgA1), anti-Gd-IgA1 autoantibodies, B cell activating factor (BAFF), a proliferation-inducing ligand (APRIL), and complement components, as well as the targeted therapies they have informed. In addition, urinary biomarkers and multi-omics approaches show promise for dynamic disease monitoring and individualized risk stratification.

Elderly patients with primary membranous nephropathy (PMN) exhibit significant prognostic heterogeneity and poor tolerance to immunotherapy. However, there is a lack of early prognostic prediction tools specifically for this population. This study aimed to develop a prognostic prediction model applicable to elderly PMN patients.

Objective To analyze ancient prescriptions for knee osteoarthritis(KOA),and explore their application patterns,for providing clinical reference value.Methods Prescriptions were collected from ancient documents,and a database was created by using Excel 2016 for frequency analysis.Association rules and hidden structures were analyzed by using SPSS Modeler 18.0 and Lantern 5.0.Results A total of 373 prescriptions and 421 herbs were collected,with 3894 times of frequency of medication.Danggui was the most frequently used herb.Herbs primarily tonified deficiencies,relieved exterior symptoms,and expelled wind-dampness,with warm properties and pungent,sweet,or bitter tastes,mainly targeting the spleen and kidney meridians.Thirteen strong association rules were identified,including Chuanxiong+Niuxi-Danggui,and Bixie-Niuxi.Hidden structure analysis revealed 10 variables,leading to 4 clusters and 4 core prescriptions.Common syndromes included wind-damp,wind-cold-damp,wind-damp-heat,and qi-blood deficiency.Conclusion The treatment of KOA in ancient literature focuses on dispelling wind and removing dampness,taking into account both positive deficiency and evil excess,flexible use of tonifying spleen and kidney,clearing dampness-heat,tonifying Qi and blood and other drugs.

Objective To analyze the main epidemiological characteristics of fungal infection in this hospital in the past 7 years,and to provide reference for clinical treatment and prevention and control strategies of fun-gal infection.Methods The fungal data and clinical data of related patients isolated from clinical samples in Peking Union Medical College Hospital from early January 2018 to the end of May 2024 were selected,and the main epidemiological characteristics of fungal infection in this hospital were identified and described through multi-angle statistical analysis.Results A total of 4 479 patients with filamentous fungal infection were en-rolled.The proportion of male patients[57.5％(2 576/4 479)]was higher than that of female patients[42.5％(1 903/4 143)],mainly distributed in internal medicine,Intensive Care Unit(ICU)and emergency de-partment,among which internal medicine accounted for the highest proportion[50.0％(2 241/4 479)].About 90.0％of the specimens were from the lower respiratory tract,in addition to specimens from skin and soft tis-sue,tissue,ear and blood culture.In terms of seasonal distribution,there are more patients in winter.The fun-gi were mainly composed of Aspergillus,Mucor,Cerdosporium,Fusarium and Penicillium,among which As-pergillus was the most abundant,accounting for 74.6％of the total.Aspergillus fumigatus was the most a-bundant Aspergillus,accounting for 42.5％of the total Aspergillus(1 418/3 340).Among the related infec-tions caused by mold,Aspergillus was the most common in the lower respiratory tract,accounting for 76.8％.Among them,Aspergillus fumigatus accounted for the highest proportion(33.6％).98.6％of the molds infected the ear were Aspergillus,of which Aspergillus niger and Aspergillus terreus were the most common.Skin infections are mainly caused by Sporothrix schenckii,Trichophyton rubrum,Microsporum ca-nis.The results of in vitro drug sensitivity test showed that the four common Aspergillus isolated in this hos-pital were sensitive to voriconazole,and amphotericin B had better antifungal activity against Mucorales in vitro.Conclusion Based on the main epidemiological characteristics of fungal infections in this hospital,it is recommended that special attention be paid to the admission of patients in the respiratory department during the peak infection period in autumn and winter.In the treatment of fungal infections in different regions and on different body parts,attention should be paid to the differences in the distribution of bacterial species.

Objective Previous studies have suggested that bilateral 5-Hz microcurrent stimulation has a hypnotic effect,but the lack of evidence on how the stimulation affects subjects'sleep limits the validation of this intervention.To address this gap,a crossover experimental design was employed,recruiting both insomnia and non-insomnia subjects.Methods 10 participants with insomnia and 10 healthy participants were selected to attend our study.In this crossover study,true(5 Hz)vs.sham stimulation was applied over the parietal temporal lobes.Impact of stimulation on subjective sleep experience,sleep efficiency,sleep structure and psychomotor vigilance task(PVT)was assessed.Results Subjects who received the true 5-Hz stimulation before bedtime had significantly enhanced sleep efficiency,sleep quality,and mental state compared to the night of sham stimulation.Additionally,subjects who received true stimulation exhibited higher sleep efficiency and a later appearance of dream sleep.These findings suggest that 5-Hz microcurrent stimulation before bedtime can enhance both objective and subjective sleep efficiency.Conclusion 5 Hz microcurrent stimulation before bedtime improved sleep efficiency of subjects and also enhanced their subjective perception of sleep.

OBJECTIVE: To explore the clinical phenotype and genetic characteristics of a child with Progressive familial intrahepatic cholestasis type 8 (PFIC8). METHODS A child with PFIC diagnosed at Beijing Children's Hospital Affiliated to Capital Medical University in September 2025 was selected as the study subject. Peripheral venous blood samples were collected from the child and her parents. Following extraction of genomic DNA, whole-exome sequencing (WES) was carried out. Candidate variants were validated by Sanger sequencing. The pathogenicity of the candidate variants was classified based on the guidelines from American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of Beijing Children's Hospital Affiliated to Capital Medical University (Ethics No.: 2023-E-126-Y). RESULTS: The proband, a 2-month-old female infant, had manifested jaundice of the skin and sclera, and slightly distended abdomen. She had no visible abdominal wall varicose veins, soft abdomen, and no palpable masses. Biliary atresia was ruled out by intraoperative cholangiography. WES revealed that she has harbored compound heterozygous variants of KIF12 gene, namely c.809C>T (p.Ala270Val) and c.1313G>A (p.Arg438Lys), which were verified by Sanger sequencing to have derived from her mother and father, respectively. According to the ACMG guidelines, both variants were classified as variants of uncertain significance (VUS). Based on the pre-defined search strategy, 10 articles were retrieved, which involved 25 PFIC cases, including 5 from China. Together with the proband of this study, the 26 PFIC patients have primarily presented with high GGT cholestasis, with the genetic cause in all cases attributed to variants of the KIF12 gene. CONCLUSION The c.809C>T and c.1313G>A compound heterozygous variants of the KIF12 gene probably underlay the pathogenesis of cholestatic liver disease in this child. Above findings have enriched the mutational and phenotypic spectra of PFIC8.

BACKGROUND:With the rise of sports medicine,neuromuscular training has become a popular area of research in recent years,and a large number of results have been achieved.However,existing research lacks a comprehensive and systematic review,underscoring the need for a holistic and systematic synthesis to elucidate the current status,key issues,and trends in this field.OBJECTIVE:To conduct a comprehensive overview of the current status,characteristics,and trends of research in the field of neuromuscular training.METHODS:A search of the Web of Science Core Collection database was conducted for peer-reviewed English-language journal articles regarding neuromuscular training.Conference papers,reviews,book chapters,and irrelevant papers were excluded,and a total of 3 102 core literature items were included.The bibliometric and visualization analyses of the included literature were conducted using the VOSviewer 1.6.20 and Citespace software.RESULTS AND CONCLUSION:(1)Research in the field of neuromuscular training has entered a phase of sustained growth in the last decade.(2)The University of Cincinnati is the most influential institution in this field,having fostered a closely cooperating research team,including Prof.Gregory D.Myer,who has made significant contributions to the development of the field.The American Journal of Sports Medicine is the most prominent journal in this field,and because of its multifaceted strengths,the United States dominates research in this area.(3)The research topics that have attracted the greatest attention include neuromuscular control(centrality:0.09),injury(centrality:0.02),and kinesiology(centrality:0.06).The research in this field is characterized by a systematic,prospective,effective and applied approach.The mechanisms of injury rehabilitation and functional reconstruction,characteristics of sports performance and intervention strategies,rehabilitation training methods and countermeasures,and risk prevention interventions and validation of the effects are the focus of the researchers'continuous attention.(4)The principal burst words include anterior cruciate ligament(emergent intensity:33.23)and activation(emergent intensity:22.7).The evolution of research frontiers indicates a shift in perspective from localization to systematic integration.The research objective has transitioned from a primary focus on prevention and treatment to a more holistic approach that encompasses capacity enhancement.Additionally,the emphasis has shifted from merely activating the process to achieving precise control.(5)It is recommended that future research should further promote cross-disciplinary collaboration and facilitate the development of neuromuscular training towards diversification,individualization and long-term effectiveness.

AIM: To explore the efficacy of internal limiting membrane(ILM)flap technique and simple ILM peeling in the treatment of idiopathic macular hole(IMH)and related influencing factors.METHODS: A retrospective cohort study was conducted on totally 32 patients(35 eyes)with IMH who received surgery at our department from January 2023 to November 2024. All the patients simultaneously received phacoemulsification combined with intraocular lens implantation, and they were divided into study group(19 eyes)and control group(16 eyes), with ILM flap technique and simple ILM peeling received in the two groups, respectively. The closure situation of macular hole, best corrected vision acuity(BCVA), and macular structure were observed in the two groups of patients. Furthermore, the correlation of BCVA and healing type of macular hole at the last time of follow-up with each parameter was analyzed.RESULTS: There was no statistical difference between the two groups of patients in preoperative general characteristics(all P>0.05). At the last time of follow-up, the macular hole was heeled in both groups, with 7 eyes of U-shaped heeling, 6 eyes of V-shaped heeling, and 6 eyes of irregular heeling in the study group, and with 13 eyes of U-shaped of heeling, 1 eye of V-shaped heeling and 2 eyes of irregular heeling in the control group(χ2=7.167, P=0.028). The postoperative BCVA was better than preoperative level(all P<0.05), there were no statistical significant differences between the two groups of patients in macular choroidal thickness before and after surgery(P>0.05), but the macular retinal thickness of the study group was thinner than that of the control group(168.11±92.11 vs 235.56±92.18 μm, P=0.03). Pearson correlation analysis indicated that BCVA at the last time of follow-up was positively correlated with the preoperative minimum diameter(r=0.476, P<0.05)and the diameter hole index(r=0.361, P<0.05), and negatively correlated with traction hole index(r=-0.364, P=0.031); Keendall correlation analysis showed that the postoperative closure types positively correlated with the basal diameter(τ=0.296, P=0.029), minimum diameter(τ=0.366, P=0.007), and visual acuity at the last time of follow-up(τ=0.412, P=0.003), while negatively correlated with macular hole index(τ=-0.415, P=0.002)and traction hole index(τ=-0.511, P<0.01). During the follow-up period, neither group of patients experienced postoperative complications.CONCLUSION: Both ILM flap technique and simple ILM peeling are safe and effective in treating IMH. As the smaller the basal diameter and minimum diameter of the macular hole, the larger the macular hole index and traction hole index, the probability of U-shaped heeling after surgery is greater and the visual acuity is better.

Objective:To analyze the current status, hotspots, and trends of community integration (CI) at home and abroad, providing directions for subsequent research.Methods:The China National Knowledge Infrastructure and the Web of Science Core Collection data were used, and CiteSpace software was employed to analyze the publication, countries, disciplines, and keywords of CI.Results:A total of 932 Chinese and 2 319 English hits were included. The publication of CI had shown an increasing trend both domestically and internationally. Sociology and rehabilitation were the main disciplines in CI domestically and internationally, respectively. Domestically, CI research primarily focused on the community integration of migrant workers, floating populations, and accompanying family members. Internationally, the emphasis was on the integration of individuals with disabilities and other special groups. Future research directions in China were likely to focus on group work, the elderly, and relocated populations. Internationally, CI research would continue to concentrate on CI experiences and intervention methods for individuals with disabilities and special populations.Conclusion:CI is increasingly gaining attention both domestically and internationally. However, domestic research remains insufficient and needs to be expanded through more empirical studies in various vertical subfields. Future domestic scholars should continue to focus on CI of the elderly and engage in interdisciplinary research.
