Attention deficit hyperactivity disorder （ADHD） is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind， which leads to disharmony between the body and spirit， resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids， calming ministerial fire， and extinguishing endogenous wind （内风）. The method of nourishing yin fluids is applied throughout the entire treatment process， commonly using ingredients such as Shudihuang （Rehmanniae Radix Praeparata）， Shanzhuyu （Corni Fructus）， Gouqizi （Lycii Fructus）， Wuweizi （Schisandrae Chinensis Fructus）， and Tusizi （Cuscutae Semen）. These are combined with approaches to harmonize the zang-fu organs， primarily including extinguishing liver wind， clearing heart fire， nourishing kidney water， and strengthening spleen earth， thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally， emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

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.

AIM: To investigate the correlation between serum Sestrin 2(SESN2), signal peptide, CUB and EGF-like domain-containing protein 1(SCUBE-1), and longpentraxin 3(PTX3)levels, with disease severity and prognosis in patients with diabetes macular edema(DME). METHODS:Prospective study. The study included DME patients who were treated at the hospital between January 2023 and October 2024, as well as patients with type 2 diabetes mellitus(T2DM)and healthy individuals who underwent physical examinations during the same period. Serum levels of SESN2, SCUBE-1, and PTX3 were measured using the ELISA method. Factors influencing poor prognosis in DME patients were analyzed. RESULTS:This study included a total of 114 eye from 114 DME patients, For unilateral disease, the affected eye was enrolled; for bilateral disease, the more severely affected eye was selected for enrollment.(72 men and 42 women, with a mean age of 56.94±7.38 y), 114 T2DM patients(65 men, 49 women, mean age 56.18±7.22 y), and 114 healthy individuals(77 men, 37 women, mean age 56.33±7.26 y). There were no cases of loss to follow-up. FPG and HbA1c levels in the DME and T2DM groups were significantly higher than those in the healthy group(all P<0.05). Serum SESN2 levels decreased progressively from the healthy group to the T2DM group to the DME group, while SCUBE-1 and PTX3 levels increased progressively(all P<0.05). DME patients were classified by disease severity into a mild group of 23 cases(14 men, 9 women, mean age 55.81±7.52 y), a moderate group 54 cases(35 males, 19 females, mean age 56.97±7.35y), and a severe group 37 cases(23 males, 14 females, mean age 57.60±7.41 y). Serum SESN2 levels decreased progressively from the mild to the moderate and to the severe group, while SCUBE-1, PTX3, and CST levels increased progressively(all P<0.05). Serum SESN2 levels were negatively correlated with DME severity and CST, whereas SCUBE-1 and PTX3 levels were positively correlated with both DME severity and CST(all P<0.001). Among the 114 DME patients, 81 were in the favorable prognosis group and 33 were in the unfavorable prognosis group. In the poor prognosis group, serum SESN2 levels were lower than those in the favorable prognosis group, while SCUBE-1 and PTX3 levels were higher(all P<0.05). Low serum SESN2 levels, high SCUBE-1 levels, and high PTX3 levels were factors associated with poor prognosis in DME patients(all P<0.05). The AUC(0.916)for the combined prediction of poor prognosis in DME patients using serum SESN2, SCUBE-1, and PTX3 levels was higher than that for each marker individually(0.780, 0.782, and 0.783, respectively, all P<0.05). CONCLUSION:Serum SESN2 levels are reduced in DME patients, while SCUBE-1 and PTX3 levels are elevated. Changes in these three markers are associated with disease severity and prognosis, and the combined detection has high predictive value for poor patient outcomes.

Background: Malignant pleural effusion (MPE), a common complication of advanced cancers, is associated with poor prognosis and reduced quality of life. Although host–tumor interactions are known to drive MPE development, the associated immune dynamics during disease progression remain unclear. Using a Lewis lung carcinoma-induced MPE model in C57BL/6JNidfc mice, we systematically evaluated general parameters and immune cell changes at two-day intervals throughout disease progression. Results: The day of Lewis lung carcinoma cell injection into the pleural space was designated as day 0. By day 10 post-injection (p.i.), MPE-bearing mice exhibited ~ 10% body weight loss, marking the experimental endpoint. Pleural tumor mass and pleural effusion volume were minimal up to day 4 p.i. but increased sharply from day 6 onward.CD45⁺ immune cell counts rose over time, and days 6, 8, and 10 p.i. marked key stages of MPE progression. On day 6, B cells, T cells, and natural killer cells, but not macrophages and neutrophils, increased significantly compared to earlier timepoints. By day 8, all immune cell subsets except T cells exceeded day 6 levels, and at day 10, natural killer cell numbers declined while others continued to increase. Besides, the numbers of CD8⁺ T cells, Th1 cells, regulatory T cells, and M2 macrophages progressively increased from day 6 to 10. Based on these data, days 6 and 10 were defined as early and advanced MPE stages, respectively, with distinct immune phenotypes. In advanced MPE, CD8⁺ T cells displayed reduced IFN-γ, TNF-α, Granzyme B, Perforin, FasL, and Ki-67, but upregulated PD-1 and CTLA-4 relative to early stage. Similarly, Th1 cells showed decreased IFN-γ, TNF-α, and IL-2 production along with reduced Ki-67 expression. Advanced-stage M2 macrophages exhibited lower MHC-II levels and impaired phagocytosis, but higher PD-L1 and IL-10 production, while neutrophils showed reduced TNF-α release and phagocytic activity. Conclusions Our findings characterize the temporal immune dynamics associated with MPE progression in a mouse model, revealing a transition from an early immunostimulatory state to a late immunosuppressive state. This study enhances our understanding of MPE immunopathogenesis and provides a foundation for developing precise, stagespecific therapeutic strategies.

Objective:To explore the value of the vesical imaging-reporting and data system (VI-RADS) score based on multiparametric MRI (mpMRI) combined with quantitative tumor MRI parameters in assessing the muscle invasion of bladder cancer.Methods:The study was a case-control study. The data of 87 bladder cancer patients confirmed by pathology who underwent mpMRI of the bladder were retrospectively collected from the First Medical Center of Chinese PLA General Hospital between January 2019 and April 2023 The pathological findings were used as the gold standard to categorize them into the muscle invasive bladder cancer (MIBC) group (29 cases) and non-muscle invasive bladder cancer (NMIBC) group (58 cases). Quantitative parameters were measured based on preoperative mpMRI images, including the length of tumor bladder wall contact, the perpendicular distance between the bladder tumor and the tangent of the bladder wall, the maximal diameter of the bladder tumor, and the volume of the bladder tumor. Bladder cancer was classified according to the VI-RADS scoring criteria. The Mann-Whitney U test was used for intergroup comparisons. Multivariate logistic regression analysis was performed to obtain the independent risk factors related to muscle invasion of bladder cancer and to establish the model. The receiver operating characteristic curves were analyzed for MRI quantitative parameters and logistic regression models, and area under the curve (AUC) comparisons were performed using the DeLong test. Results:The differences in tumor bladder wall contact length, perpendicular distance from the tumor to the tangent line of the bladder wall, maximum diameter, bladder tumor volume, and the VI-RADS scores were statistically significant between the MIBC group and the NMIBC group ( P<0.05). Multifactorial logistic regression analysis showed that tumor bladder wall contact length ( OR=21.07, 95% CI 3.56-124.89, P=0.001) and VI-RADS score ( OR=11.90, 95% CI 3.53-40.12, P<0.001) were the independent risk factors for evaluating the muscle invasion of bladder cancer. The difference between the VI-RADS score and the tumor bladder wall contact length for assessing muscular infiltration of bladder cancer had AUCs of 0.802 (95% CI 0.704-0.899) and 0.759 (95% CI 0.652-0.865). The combined model of VI-RADS score combined with tumor bladder wall contact length had an AUC of 0.891 (95% CI 0.812-0.970), which was higher than the diagnostic efficacy of applying tumor bladder wall contact length or VI-RADS score alone ( Z=3.05, 2.37, P=0.002, 0.018). Conclusion:Tumor contact length with the bladder wall is an independent risk factor for assessing muscle invasion of bladder cancer and the combination of VI-RADS score may enhances diagnostic accuracy.

Objective To investigate the awareness of female patients with pelvic floor dysfunction regarding minimally invasive laser treatment of the reproductive tract and analyze the factors influencing their decision-making intentions,this study aims to provide a foundation for early treatment of pelvic floor dysfunction and further development in reproductive health management.Methods A convenience sampling method was employed to select 164 female patients with pelvic floor dysfunction who sought treatment at the Pelvic Rehabilitation Center of Dongguan Maternal and Child Health Care Hospital between June 2023 and August 2024.The study utilized the Female Sexual Function Index,Incontinence Quality of Life Questionnaire,and Family Support Self-Assessment Scale to conduct a survey.Binary logistic stepwise regression analysis was conducted to investigate the factors influ-encing patients'inclination towards undergoing genital laser minimally invasive treatment.Results Among the 164 female patients,143(87.2%)expressed an intention to receive treatment,with 22.6%demonstrating a rela-tively clear understanding of genital laser minimally invasive treatment.Logistic regression analysis revealed that occupation significantly influenced treatment intention(P<0.05).Compared to healthcare professionals,individuals in the teaching profession(OR=10.81,95%CI:1.04～112.21),self-employed individuals(OR=20.34,95%CI:3.46～119.43),and those in other professions(OR=16.26,95%CI:4.05～65.29)were more inclined to express willingness for undergoing treatment.Furthermore,a lower score on the Incontinence Quality of Life scale was found to positively correlate with treatment intention(OR=0.96,95%CI:0.93～0.99).Conclusion Although patients express a high intention to undergo minimally invasive genital laser treatment,their overall awareness of the procedure remains insufficient.

To investigate the effects of plasma exosomes from sheep on animal hair growth,exo-somes were extracted from two sheep breeds with significant differences in wool fineness(Xinji Fine-wool sheep and Small-tailed Han sheep)using biphasic precipitation.The exosomes were characterized by transmission electron microscopy(TEM)and nanoparticle tracking analysis(NTA).A murine alopecia areata model was established,followed by subcutaneous injection of ex-osomes for 7 consecutive days.Dorsal skin samples were collected on day 10 post-injection for his-tological analysis via hematoxylin-eosin(HE)staining.miRNA and mRNA libraries were constructed through qPCR,while TargetScan and g:Profiler were employed for target gene predic-tion and KEGG enrichment analysis,respectively.Protein-protein interaction(PPI)networks were analyzed using STRING to identify key miRNA-mRNA targets,which were preliminarily validated by qPCR.Results demonstrated that on day 5 post-injection,the Small-tailed Han sheep plasma ex-osome group(SPE)exhibited more melanin deposition spots compared to the Xinji Fine-wool sheep plasma exosome group(XPE),with XPE showing greater melanin spots than the control group(NC).Histological analysis revealed that XPE group displayed significantly fewer hair folli-cles compared to SPE and NC groups(P＜0.01),while SPE group exhibited significantly larger hair follicle diameters than both XPE and NC groups(P＜0.01).Bioinformatics analysis predicted 357,711,477,346,and 3 178 target genes for miR-150,miR-133b,miR-31-5p,miR-433-3p,and miR-218,respectively,with 508 genes being co-regulated by two or more miRNAs.PPI analysis i-dentified 217 genes involved in positive regulation of cellular processes,109 in developmental regu-lation,133 in cellular development,132 in cell differentiation,and 69 in regulation of cell differenti-ation.Target genes were found to regulate hair follicle growth through Wnt signaling via Frizzled receptor binding and downstream pathways involving calmodulin(CaM)and cyclic-AMP response binding protein(CREB).qPCR validation showed significantly higher relative expression levels of miR-218,miR-150,miR-31-5p,miR-133b,and miR-433-3p in SPE and XPE groups compared to NC,with SPE exhibiting greater expression than XPE.Additionally,significant differences in FZD4,WNT4,CREB1,and FZD3 expression were observed between treatment groups and NC.These findings demonstrate that plasma exosomes from Xinji Fine-wool and Small-tailed Han sheep modulate hair growth by altering miRNA-mRNA expression profiles in skin tissues.
