ObjectiveTo investigate the protective effect and mechanism of Wendan Ningxin granules （WNG） on susceptibility to atrial fibrillation （AF） in mice with inflammatory injury. Methods100 C57BL/6 mice were divided into a blank control group， a model group， a low-dose WNG group （2.34 g·kg^-1·d^-1）， a high-dose WNG group （4.68 g·kg^-1·d^-1）， and an amiodarone positive control group （0.091 g·kg^-1·d^-1）， with 20 mice in each group. Except for the blank control group， mice in other groups received intraperitoneal injections of lipopolysaccharide （LPS） to establish an inflammatory injury model. Treatment groups received continuous intragastric administration of their respective interventions for four weeks. During the fourth week， the treatment groups received LPS injections concurrently with their treatments. The blank control and model groups received distilled water （10 mL·kg^-1·d^-1） by gavage， with a gavage volume of 10 mL·kg^-1 for all groups， once daily. Hematoxylin-eosin （HE） staining and Sirius red staining were used to observe atrial tissue morphology and fibrosis degree. Immunohistochemistry was used to assess the expression of α-smooth muscle actin （α-SMA） in mouse atrial tissue. Electrophysiological detection was performed using a multi-channel electrophysiology mapping system to measure AF inducibility， AF duration， and atrial effective refractory period （AERP）. High-resolution optical mapping was used to measure action potential duration （APD） dispersion， conduction heterogeneity index， and calcium transient （CaT） dispersion. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of proteins related to diastolic calcium leakage in mouse atria： Ca²⁺/calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）， ryanodine receptor 2（RyR2）， sarco/endoplasmic reticulum Ca²⁺-ATPase （SERCA）， and sodium-calcium exchanger （NCX）. Western blot analysis was performed to detect the expression of CaMKII， RyR2， SERCA， and NCX proteins in myocardial tissue from each group. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of inflammatory factors interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α）. ResultsPathological staining results showed that compared with the blank control group， the model group exhibited disrupted atrial tissue structure， inflammatory cell infiltration， atrial fibrosis， and diffuse infiltration of numerous brown α-SMA positive cells in the atrial interstitium （P<0.01）. AF could be induced by electrical stimulation with a longer duration. AERP was shortened， while APD dispersion， conduction heterogeneity index， and CaT dispersion were increased （P<0.01）. The expression of proteins associated with diastolic calcium leakage， including CaMKⅡ， RyR2， and NCX1， showed elevated mRNA and protein levels， whereas SERCA2a mRNA and protein expression decreased （P<0.05）. Serum levels of inflammatory factors IL-1β and TNF-α were elevated （P<0.01）. Compared with the model group， intervention with WNG alleviated cardiac structural damage， reduced inflammatory cell infiltration， improved atrial fibrosis， and reduced the diffuse infiltration of α-SMA positive cells （P<0.01）. AF inducibility and AF duration upon electrical stimulation were significantly reduced （P<0.05）， AERP was prolonged （P<0.05）， mRNA and protein expression of CaMKⅡ， RyR2， and NCX1-proteins associated with diastolic calcium leakage-were reduced， whilst mRNA and protein expression of SERCA2a increased （P<0.05）， and serum levels of IL-1β and TNF-α were decreased （P<0.01）. ConclusionBoth low‑ and high‑dose WNG can effectively reduce susceptibility to inflammation-related AF. The mechanism by which WNG reduce AF susceptibility may be related to regulating proteins involved in sarcoplasmic reticulum diastolic calcium leak， thereby improving cardiac electrical remodeling， and alleviating inflammation-induced myocardial fibrosis， thus improving cardiac structural remodeling.

Based on the theory of "shaoyang（少阳） resembling the pivot" and collateral diseases， this article proposes that pulmonary fibrosis （PF） can be divided into three stages including wind bi （痹）， constraint bi， and atrophy bi. The core pathogenesis of PF is the obstruction of the pivot and pulmonary collateral obstruction. In terms of treatment， the basic principles are to harmonize and regulate the pivot， and to promote the circulation of the lung collaterals. Depending on the different characteristics of the "essence-attribute-function"， treatment methods such as harmonizing and regulating the pivot， resolving phlegm and removing stasis， supplementing deficiency and harmonizing collaterals are suggested. This approach ensures the regulation of the pivot， smooth circulation of qi and blood， unblocking of the lung collaterals and nourishing the lung body， achieving the goals of balancing the ascending and descending of qi， removing phlegm and stasis， and relieving cough and wheezing.

Objective To explore the research hotspots and developmental trends in urological education through a bibliometric analysis. Methods Relevant literature on urological education was retrieved from the Web of Science Core Collection and the China National Knowledge Infrastructure (CNKI) databases, covering all records up to Sep.16, 2025.A comprehensive bibliometric analysis was performed on the retrieved publications. Results A total of 303 Chinese and 290 English articles were collected.The annual number of publications demonstrated an overall upward trend.Harvard University in the United States was the most productive institution in this field. Conclusion Urological clinical education has attracted increasing attention from clinicians and medical trainees.Highly cited studies consistently highlight three actionable priorities for urological education:firstly, improving long-term knowledge retention through structured, spaced, and feedback-rich learning designs; secondly, standardizing simulation-based skills training with validated assessment and staged credentialing; thirdly, strengthening training system resilience while expanding non-technical skills training.These directions provide implementable pathways for optimizing urological teaching practices and the standardized residency training programs.

The aim of this updated guideline is to provide comprehensive recommendations for the management of gout in patients with common comorbidities, such as chronic kidney disease(CKD), cardiovascular disease(CVD), diabetes, osteoarthritis(OA), and gastrointestinal disorders. This guideline was developed by a multidisciplinary expert panel consisting of specialists in endocrinology, rheumatology, nephrology, cardiology, gastroenterology, and methodology. The development process adhered to standard methodologies, including PICO(population, intervention, comparator, and outcomes) question deconstruction, systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation(GRADE) for evidence and recommendation evaluation, Delphi voting, and expert consensus. The guideline presents 26 evidence-based recommendations addressing 7 clinical questions for patients with hyperuricemia and gout in the context of comorbidities. Key recommendations include the maintenance of strict serum urate targets, particularly for patients with CKD stage≥3, chronic gouty arthritis, and OA, in order to prevent disease progression. In patients with CVD or diabetes, intra-articular triamcinolone is preferred over systemic glucocorticoids. Prioritized anti-inflammatory treatments for patients with CKD, gastrointestinal diseases and OA are recommended. The guideline also introduces emerging therapies, such as interleukin-1 inhibitors and selective urate transport inhibitors, as potential treatment options for refractory cases. The update offers a comprehensive, patient-centered approach to managing gout, particularly in individuals with associated comorbidities. Multidisciplinary collaboration and emerging new treatments and evidence ensure the optimization of the recommendations.

We report a family with multiple endocrine neoplasia type 1(MEN1), in which the proband presented with primary amenorrhea and was diagnosed with both a pituitary prolactinoma and an ACTH-secreting adenoma. Genetic testing identified a heterozygous MEN1 gene c. 1449_1476del mutation in the proband, as well as in six additional family members, who exhibited variable clinical phenotypes. Following initial transsphenoidal pituitary surgery, the proband's symptoms and biochemical abnormalities persisted, with elevated ACTH and cortisol levels. Functional imaging using [ 68Ga]-DOTA-TATE PET/CT confirmed residual pituitary tumor tissue, and a second surgery resulted in biochemical remission.

This article reported a case of autosomal dominant intellectual developmental disorder type 22 caused by a heterozygous mutation in the ZBTB18 gene. At 24 +4 weeks of gestation, prenatal ultrasound indicated a short outer diameter of the fetal corpus callosum and bilateral ventricular dilatation. Whole-genome copy number variation analysis of the fetus showed no abnormalities. Whole exome sequencing (WES) and Sanger sequencing validation of the family revealed the fetus carried a c.1374_1383del(p.S459*) heterozygous mutation in the ZBTB18 gene (NM_205768.3), which was neither phenotypically present nor genotypically detected in the parents, suggesting a de novo mutation. Based on the clinical manifestations, the fetus was diagnosed with autosomal dominant intellectual developmental disorder type 22. After genetic counseling, the pregnant woman opted for termination of the pregnancy. This case highlights the correlation between prenatal ultrasonic detection of callosal dysgenesis and lateral ventricular enlargement and intellectual developmental disorders caused by gene mutations. Furthermore, it expands the mutation spectrum of the ZBTB18 gene, thereby facilitating prenatal diagnosis and genetic counseling.
