Myasthenia gravis is an autoimmune disorder characterized by impaired neuromuscular transmission. Thymectomy is one of the therapeutic options for acetylcholine receptor antibody-positive myasthenia gravis patients. The quality of perioperative care is directly associated with surgical safety and patient outcomes. However, there is currently a lack of specialized nursing consensus or guidelines specifically addressing the care of these patients domestically or internationally. To promote the standardization and normalization of perioperative nursing care for myasthenia gravis patients undergoing thymectomy and to ensure treatment efficacy, a panel of 57 experts from relevant fields was convened. Based on evidence-based medicine and clinical practice experience, discussions were held on various aspects including condition assessment, nutritional support, medication management, and airway care, resulting in a consensus with 18 final recommendations by using the Delphi method through two rounds of expert consultation. This consensus aims to provide a scientific reference for the perioperative nursing care of myasthenia gravis patients undergoing thymectomy.

ObjectiveTo observe the effect of heat-sensitive moxibustion on quality of life and immune function in non-small cell lung cancer （NSCLC） patients undergoing chemotherapy. MethodsSeventy NSCLC patients with qi deficiency and phlegm stasis syndrome were randomly divided into an intervention group and a control group， with 35 cases in each group. The control group received chemotherapy combined with routine symptomatic treatment， while the intervention group additionally received heat-sensitive moxibustion since the first day of chemotherapy. Acupoints included Dazhui （GV14）， bilateral Feishu （BL13）， Zhongwan （CV12）， Qihai （CV6）， and Guanyuan （CV4）. The site exhibiting the strongest heat-sensitization response was selected for moxibustion. Treatment was administered for 45 minutes per session， three times weekly for three consecutive weeks， totaling nine sessions. Before and after treatment， quality of life was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire （EORTC QLQ-C30）， and traditional Chinese medicine （TCM） syndrome scores were evaluated. Peripheral blood levels of natural killer （NK） cells and T-lymphocyte subsets including CD3⁺， CD4⁺， and CD8⁺， and CD4⁺/CD8⁺ ratio were measured. Levels of programmed cell death protein-1 （PD-1）， including PD-1⁺CD4⁺ and PD-1⁺CD8⁺ cells， were also assessed. Liver and renal function were monitored before and after treatment， and adverse events were recorded. ResultsIn the intervention group， 1 participant withdrew and 1 was excluded， while in the control group， 2 participants withdrew. Ultimately， 33 participants in each group were included in the final analysis. The intervention group showed significant improvements in physical， role， emotional， cognitive， and social functioning， as well as global health status after treatment， while scores for fatigue， nausea and vomiting， dyspnea， appetite loss， diarrhea， and TCM syndrome scale were significantly decreased （P＜0.05）. Moreover， the intervention group demonstrated higher scores in physical functioning， role functioning， and global health status， as well as lower scores for fatigue， nausea and vomiting， dyspnea， appetite loss， diarrhea， and the TCM syndrome scale than the control group （P＜0.05）. After treatment， the levels of peripheral NK cells and PD-1⁺CD8⁺ T cells in the intervention group increased significantly； furthermore， the intervention group exhibited higher peripheral NK cell levels and lower PD-1⁺CD8⁺ T cell levels than the control group （P＜0.05）. No significant differences were found in liver or renal function between the two groups （P＞0.05）. In addition， no adverse events such as burns or moxibustion-induced syncope occurred during the study. ConclusionHeat-sensitive moxibustion as an adjunctive therapy may enhance immune function， alleviate clinical symptoms， and improve quality of life， while demonstrating a favorable safety profile in NSCLC patients with qi deficiency and phlegm stasis.

Bronchiolar adenoma (BA) is a rare type of lung tumor characterized by bilayered epithelial cells having a continuous basal layer and a luminal layer. It resembles mucinous adenocarcinoma (MA) on frozen section, with difficulty in distinguishing the basal layer. Immunohistochemistry is the best choice for verifying the diagnosis. This study aimed to comprehensively characterize three cases of BA-combined carcinoma using clinical, histopathological, and genetic features. BA and carcinoma sections were subjected to next-generation sequencing, respectively. It was hypothesized that while different mutation forms matched different regions, BA and lung adenocarcinoma shared the same gene mutation when they co-occurred in the same location. BA with extensive carcinoma is extremely rare and presents diagnostic challenges due to its overlap with conditions such as MA. Because of its distinctive morphological characteristics, BA may be regarded as a low-grade malignancy, particularly during a confusing evaluation. A multifaceted examination of clinical, radiological, immunohistochemical, and genetic data is necessary for an accurate diagnosis.

ObjectiveThe present study aimed to investigate alterations in white matter microstructure and spontaneous neural activity in male college smokers, and to further explore their associations with nicotine dependence. Given that adolescence and early adulthood represent critical periods for brain maturation, particularly for white matter development, understanding the neural correlates of smoking behavior during this stage is of substantial importance for both neuroscience and public health. MethodsA total of 115 male undergraduate students were initially recruited for this study. After quality control and exclusion procedures, 52 male college smokers and 42 demographically matched healthy non-smokers were included in the final analysis. All participants underwent multimodal magnetic resonance imaging (MRI), including diffusion tensor imaging (DTI) and resting-state functional MRI (rs-fMRI). White matter fiber tracts were reconstructed using the automated fiber quantification (AFQ) method, which enables precise identification and quantification of major fiber bundles. Eighteen major white matter tracts were segmented for each participant. Along the core trajectory of each tract, 100 equidistant nodes were sampled. Fractional anisotropy (FA) was calculated at each node to assess white matter microstructural integrity, while amplitude of low-frequency fluctuation (ALFF) was computed to evaluate spontaneous neural activity within white matter tracts. Between-group differences in FA and ALFF were assessed using two-sample t-tests, with appropriate corrections applied for multiple comparisons. Furthermore, Pearson correlation analyses were conducted to examine the relationships between imaging-derived metrics (FA and ALFF values in regions showing significant group differences) and nicotine dependence severity, as measured by the Fagerström test for nicotine dependence (FTND). ResultsCompared with healthy non-smokers, male college smokers exhibited significantly increased FA values in several white matter tracts, including the left thalamic radiation, right corticospinal tract, forceps major of the corpus callosum, left uncinate fasciculus, and right arcuate fasciculus. These findings suggest altered microstructural organization or increased directional coherence within these pathways. In addition, smokers demonstrated significantly elevated ALFF values in the forceps major, right uncinate fasciculus, and left arcuate fasciculus, indicating enhanced spontaneous neural activity in these white matter regions. Correlation analyses revealed that FA values in the left thalamic radiation and right corticospinal tract were negatively correlated with FTND scores, suggesting that higher levels of nicotine dependence were associated with reduced microstructural integrity or altered fiber organization in these regions. In contrast, ALFF values in the forceps major and right uncinate fasciculus were positively correlated with FTND scores, indicating that greater nicotine dependence was associated with increased spontaneous neural activity in specific white matter pathways. ConclusionThe present study provides evidence that male college smokers exhibit distinct alterations in both white matter microstructure and functional activity. These abnormalities are not uniformly distributed but rather localized to specific fiber tracts implicated in sensorimotor processing, interhemispheric communication, and higher-order cognitive and emotional regulation. Importantly, the observed associations between imaging metrics and nicotine dependence severity suggest that these structural and functional alterations may reflect neurobiological mechanisms underlying addiction. The combination of AFQ-based tract profiling and multimodal MRI offers a sensitive approach for detecting subtle changes along white matter pathways, highlighting its potential utility in identifying neuroimaging biomarkers of nicotine dependence. Overall, these findings indicate that smoking during early adulthood may disrupt ongoing white matter maturation, potentially leading to long-term consequences for brain function. This study provides novel insights into the neural basis of nicotine dependence and underscores the importance of early intervention and prevention strategies targeting young smokers.

Objective To explore the effect of chrysin on intestinal flora in mice with alcoholic liver disease(ALD).Methods Mice were randomly assigned to normal control group,ALD model group,Silymarin group,chrysin low-dose group,chrysin high-dose group(25,50 mg·kg-1).The mice were fed with alcoholic liquid diet and a single dose of alcohol(5 g·kg-1)for eight weeks to establish the ALD model.After eight weeks of oral administration,each group's serum and plasma lipids and liver function indices were collected and detected using kits;then collected the liver and observed the pathological changes of the liver using HE staining;meanwhile,intestinal contents were collected and changes in mouse gut flora were analyzed by 16S rDNA sequencing.Results Compared with the ALD group,the level of aspartate transaminase(AST),alanine transaminase(ALT)and triacylglycerol(TG)of low-dose and high-dose chrysin groups were significantly reduced,and it can alleviate liver cell steatosis and inflammatory reactions caused by alcohol.16S rDNA results showed that the total number and types of intestinal flora in the ethanol group were significantly reduced,as well as a change in the dominant genus to Escherichia-Shigella and Akkermansia.Compared to the ALD model group,the Shannon index of the intestinal microbiota increased significantly in mice treated with low and high doses of chrysin.In addition,at the phylum and genus level,the abundance of the high-dose chrysin group increased significantly,resulting in an overall increase in the total number and amount of microbiota.The abundance of dominant bacterial groups,such as Oscillospirales,irmicutes,andAlloprevotella,was also significantly increased.Conclusion Chrysin may exert therapeutic effects on ALD by improving intestinal flora imbalance in ALD mice.

Objective:To observe and analyze the ocular clinical features and pathogenic genes of horizontal gaze palsy with progressive scoliosis (HGPPS).Methods:A pedigree study was conducted.Two families with HGPPS diagnosed by ophthalmology examination at Henan Children's Hospital from November 2023 to April 2024 were included, with 3 people from two generations in each family.Medical history and family history of the subjects were inquired.Vision acuity, diopter, anterior segment, intraocular pressure, wide-angle laser scanning ophthalmoscopy, optical coherence tomography, visual evoked potential (VEP), electroretinogram (ERG), ocular B-ultrasound, full spine AP+ lateral view, orbit+ skull+ cervical spine+ thoracic spine+ lumbosacral spine MRI plain scan were performed on the subjects.Whole genomic DNA was extracted from 2 ml of peripheral venous blood collected from the subjects, and gene sequencing was performed using whole exome sequencing (WES) technology.Suspicious pathogenic variant loci were verified by Sanger sequencing, and the pathogenicity of gene variant loci was analyzed according to the ACMG standards and guidelines for the interpretation of sequence variants.This study followed the Declaration of Helsinki.The study protocol was reviewed and approved by the Ethics Committee of Henan Children's Hospital (No.2024-KY-0024).All subjects and guardians signed informed consent forms and were informed of relevant matters before genetic testing.Results:The proband from family 1 was male, 3 years and 2 months old.At the age of 6 months, he was found to have head tilted to the left with a right scoliosis of the spine centered on T11-12 and no obvious abnormalities on VEP and ERG examinations.The proband from family 2 was male, 3 years and 4 months old, with a left scoliosis of the spine centered on T12.Both probands developed horizontal fixation paralysis, unable to rotate eye outward, slightly limited inward rotation, left eye hypertropia, mild horizontal nystagmus, normal vertical eye movement, backward development of major movements, and normal vision, anterior segment and fundus.MRI examination showed that the medulla oblongata was butterfly shaped, and a brainstem fissure could be seen in the center of the medulla oblongata.The genetic testing showed that the proband from family 1 had compound heterozygous variations c. 1054delC/p.Gln352Serfs *90 (M1) in exon 7 and c. 1219G>T/p.Gly407Cys (M2) in exon 8 of ROBO3 gene.The father of the proband carried M1 and the mother of the proband carried M2.The proband from family 2 had compound heterozygous variations c. 1888C>T/p.R630X (M3) in exon 12 and c. 2684C>A/p.A895E (M4) in exon 17 of ROBO3 gene.M1 and M3 were possible pathogenic, and M2 and M4 were of unknown clinical significance, and prediction software predicted M2 and M4 were harmful variations. Conclusions:The main clinical features of two HGPPS pedigree are horizontal fixation paralysis and progressive scoliosis, accompanied by nystagmus and strabismus.MRI shows brainstem fissure in the central medullary area.Four variants are novel variants, which increases the variation spectrum of ROBO3 gene.

Objective To elucidate the impact of chronic kidney disease(CKD)on the clinical outcomes of patients with left main coronary artery disease(LMCAD)undergoing intravascular ultrasound(IVUS)-guided percutaneous coronary intervention(PCI).Methods This retrospective study enrolled consecutive patients with LMCAD who underwent IVUS-guided PCI at Wuhan Asia Heart Hospital between January 2017 and December 2020.Patients were stratified into CKD and non-CKD groups according to the presence of CKD.Clinical data were systematically retrieved from the electronic health record system.Demographic,clinical,and angiographic characteristics were compared between groups.The primary endpoint was major adverse cardiovascular events(MACE),defined as a composite of all-cause mortality,myocardial infarction,and ischemic stroke.Results A total of 325 LMCAD patients[mean age(62.56±9.86)years;73.54％male]were included,with 31 patients(9.54％)in the CKD group.During a median follow-up of 5 years,CKD patients exhibited significantly older age[(70.13±9.77)years vs.(61.77±9.54)years,P＜0.001],higher prevalence of three-vessel disease(64.52％vs.38.10％;P=0.040)and left main bifurcation lesion(45.16％vs.37.76％,P=0.011),greater IVUS-detected calcification burden(P=0.029),and higher median SYNTAXⅡ scores[(34.10(30.30,39.25)vs.26.75(22.42,31.58),P＜0.001)].The cumulative incidence of MACE was significantly higher in the CKD group compared to the non-CKD group(32.26％vs.9.18％,P＜0.001).Univariate Cox regression analysis and Kaplan-Meier survival curves confirmed a 5.877-fold increased risk of MACE in CKD patients(95％CI 2.765-12.494).After adjusting for age and cardiac function,CKD remained an independent predictor of MACE(HR 3.611,95％CI 1.634-7.978).Conclusions LMCAD patients with concomitant CKD present with advanced age,impaired cardiac function,more extensive coronary disease,and severe calcification.The presence of CKD is associated with a significantly worse long-term prognosis.
