Objective To understand the current status of blood pressure variability and dyslipidemia in young and middle-aged patients with ischemic stroke, and to explore their relationship with prognosis. Methods A total of 312 young and middle-aged patients with ischemic stroke who met the inclusion criteria in Beijing Pinggu District Hospital from January 2022 to January 2025 were selected. The prognosis status [modified Rankin scale (mRS)], blood pressure variability, and blood lipids [total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)] were analyzed. The correlation of blood pressure variability and blood lipids levels with prognosis was explored by logistic regression analysis. Results There were 206 patients with good prognosis and 106 patients with poor prognosis. The number of patients who received diversified health education in the good prognosis group was more than that in the poor prognosis group (P<0.05). The systolic blood pressure successive variation (SV) and average real variability (ARV), and diastolic blood pressure SV and ARV were lower in the good prognosis group than those in the poor prognosis group (P<0.05). Furthermore, compared with the poor prognosis group, the good prognosis group had lower levels of TC, TG and LDL-C, while the number of patients receiving diversified health education and the level of HDL-C were higher (P<0.05). After logistic regression analysis, it was found that the levels of TC, TG, LDL-C, systolic blood pressure SV and ARV, and diastolic blood pressure SV and ARV were risk factors for poor prognosis. Conversely, receiving diversified health education and HDL-C level were protective factors for poor prognosis (P<0.05). Conclusion High blood pressure fluctuation, dyslipidemia, and lack of health education will increase the risk of poor prognosis in young and middle-aged stroke patients.

Chronic obstructive pulmonary disease (COPD) is the most common chronic respiratory disease around the world, and pharmacotherapy is the foremost treatment method currently. In recent decades, with the rapid development of bronchoscopic interventional therapy, endoscopic physical ablation technology presents a therapeutic effect in treating COPD, with few treatment-related side effects, showing excellent application prospects in treating COPD. Since ablation techniques in this field are emerging technologies with low patient acceptance, they are not widely used in the clinical treatment of COPD. This article reviews the development process of physical ablation techniques. Moreover, their current application status and the prospects in the field of COPD treatment are also summarized and analyzed. We hope to promote the application of physical ablation in the clinical treatment of COPD and provide practical references and a theoretical basis for the clinical treatment of COPD.

Digestive system malignant tumors （DT） are one of the leading causes of death globally and carry a heavy economic burden. Gut microbiota plays a critical role in maintaining host health， including providing nutrition， defending against pathogens， and promoting immune development. In recent years， more and more studies have shown that dysbiosis of gut microbiota is closely associated with DT such as gastric cancer， liver cancer， and colon cancer. Therefore， targeted regulation of gut microbiota plays a potential role in inhibiting the growth and metastasis of DT， while its specific regulatory mechanism remains unclear. As the studies about the anti-tumor effects of traditional Chinese medicine （TCM）， especially the basic and clinical studies on the regulation of gut microbiota by TCM in tumor treatment， have been growing， the therapeutic effects of TCM on DT have attracted much attention. This paper provides a systematic review of the relationship between gut microbiota and DT， as well as the related studies on the modulation of gut microbiota by TCM against DT， with the aim of providing a foundation and direction for future basic and clinical studies on DT. The literature review shows that gut microbiota influence the occurrence and development of DT through multiple pathways. These pathways include triggering chronic inflammation， producing oncogenic metabolites， inducing genomic instability， regulating the immune system， and altering the tumor microenvironment. TCM can exert anti-DT effects by regulating the composition of gut microbiota， modulating gut microbiota metabolites， repairing intestinal barrier function， and influencing immune functions. Therefore， understanding the relationship between gut microbiota and DT and the regulatory mechanisms of TCM may provide new strategies for future prevention and treatment of DT.

Objective:To investigate the dynamic imaging characteristics of hepatocellular carcinoma (HCC) following Yttrium-90 selective internal radiation therapy ( 90Y-SIRT) and to compare these with imaging findings after transarterial chemoembolization (TACE). Methods:This retrospective case-control study included 24 HCC patients who received 90Y-SIRT at Zhongda Hospital, Southeast University, and West China Hospital, Sichuan University, between September 2021 and June 2023, establishing the 90Y-SIRT group. Additionally, 45 HCC patients who underwent their first TACE treatment at Zhongda Hospital, Southeast University during the same period were included as the TACE group. Patients underwent MRI and/or CT follow-ups at 1-3 months (first follow-up) and 3-6 months (second follow-up) after treatment. The analyzed imaging features included tumor characteristics, peritumoral features, and measurements of tumor and liver volumes, with postoperative change rates calculated. Imaging differences between the 90Y-SIRT and TACE groups were statistically compared using the Mann-Whitney U test or χ2 test. Results:At the first follow-up, compared to baseline, a higher proportion of lesions in the 90Y-SIRT group exhibited a reduction in arterial phase enhancement in the viable region (10/13) than in the TACE group (10/29), with a statistically significant difference ( P=0.040). The necrotic region of the tumor on T 1WI showed significantly lower signal intensity in the 90Y-SIRT group than in the TACE group ( Z=2.98, P=0.006). The change in the apparent diffusion coefficient value in the viable region compared to baseline was 157.0×10 -3(-62.0×10 -3, 311.5×10 -3) mm2/s in the 90Y-SIRT group and -56.0×10 -3 (-216.8×10 -3, 110.0×10 -3) mm2/s in the TACE group, with a statistically significant difference ( Z=-2.71, P=0.008). At the first and second follow-up, the contralateral liver lobe volume increased significantly in the 90Y-SIRT group, with a statistically significant difference from the TACE group ( Z=-3.21, -3.78, both P=0.001). Regarding peritumoral imaging characteristics, a statistically significant difference was observed between the two groups in the low signal intensity of the liver lobe or segment where the tumor waslocated during the hepatobiliary phase ( P=0.020, 0.040). Both HCC groups exhibited progressive tumor volume reduction after treatment. In the 90Y-SIRT group, the change rates of lesion volume relative to baseline at the two follow-ups were -23.0% (-45.6%, 7.9%) and -68.7% (-82.7%, -28.5%), respectively. In the TACE group, the values were -29.8% (-53.6%, -2.7%) and -38.0% (-65.3%, -10.7%). The differences between the two groups were not statistically significant ( Z=-0.52, P=0.605; Z=-1.79, P=0.073). Conclusion:There is a statistically significant difference in the tumor imaging features and peritumoral imaging characteristics between 90Y-SIRT and TACE. 90Y-SIRT demonstrates a notable advantage in promoting contralateral liver lobe regeneration while also contributing to tumor size reduction.

Objective:In the context of China's cardiovascular disease(CVD)high-risk population screening and intervention project,this study systematically evaluates the applicability of the EQ-5D-5L and SF-6Dv2 instruments among individuals at high risk of CVD.Methods:Convergent validity was assessed using Spearman's correlation coefficient.Measurement agreement was evaluated through intraclass correlation coefficients(ICC)and Bland-Altman plots.Factors influencing utility differences were explored using multiple linear regression analysis.Kruskal-Wallis test and t-test were used to examine discriminant validity.Sensitivity was compared by effect size(ES),relative efficiency(RE),and the area under the receiver operating characteristic curve(ROC-AUC).Floor and ceiling effects were also compared.Results:Among 5,415 individuals at high risk of CVD,the two instruments showed moderate overall correlation and acceptable convergent validity,but dimension-specific correlations were weak,and measurement consistency was low(ICC=0.367).Both instruments effectively distinguished different health states,yet the SF-6Dv2 demonstrated superior sensitivity and a milder ceiling effect.Conclusion:When measuring the health utility value of CVD patients,scale selection should be cautious,especially for high-risk groups,and SF-6Dv2 is more appropriate.

Objective:To compare the efficacy of surgical resection and radiofrequency ablation (RFA) treatment for China liver cancer staging (CNLC) Ia hepatocellular carcinoma (HCC) at difficult-to-reach locations.Methods:A retrospective analysis was conducted on the clinical data of 114 patients with CNLC Ia HCC at Ⅶ、Ⅷ、Ⅳb or Ⅰ segments that were difficult-to-reach locations who were admitted to People's Hospital of Zhengzhou University from December 2018 to December 2023. Among the patients, 85 were males and 29 were females, aged (58.1±1.0) years. The patients were divided into two groups: a RFA group with 31 cases and a surgical resection group with 83 cases. Compare the levels of alanine transaminase (ALT) and aspartate transaminase (AST) before and after surgery, the surgical time, intraoperative blood loss, postoperative hospital stay, postoperative complications, recurrence free survival rate, and cumulative survival rate between the two groups.Results:The comparison of age, gender, ALT, and AST between the two groups showed no statistically significant differences (all P>0.05). The differences in ALT and AST levels before and after surgery in the RFA group were (134.8±38.7) U/L and (195.1±53.9) U/L, respectively, which were significantly lower than those in the surgical resection group [(226.8±17.9) U/L and (229.5±16.2) U/L] ( t=-2.45 and -1.12, P=0.016 and 0.041). The RFA group had shorter operation time [(69.2±11.7) min vs. (210.6±8.9) min], less intraoperative blood loss [(8.7±3.8) ml vs. (238.6±20.8) ml], and shorter postoperative hospital stays [(6.4±1.0) d vs. (13.1±0.4) d] compared to the surgical resection group, with all differences statistically significant (all P<0.05). The overall complication rates were 19.4% (6/31) in the RFA group and 22.9% (19/83) in the surgical resection group, showing no significant difference ( χ2=0.16, P=0.685). No statistically significant diffe-rence was found in recurrence-free survival rates between the two groups ( χ2=0.13, P=0.717). Similarly, there was no statistically significant difference in cumulative survival rates between the groups ( χ2<0.01, P=0.978). Conclusion:For HCC at CNLC Ⅰa in challenging locations, RFA demonstrated shorter operation time and postoperative hospital stay, less intraoperative bleeding, and superior liver function recovery compared with surgical resection, while no significant difference was observed in survival outcomes between the two treatment groups.

OBJECTIVE: To explore the genetic etiology of two fetuses with Mosaic variegated aneuploidy syndrome (MVA) in a pedigree. METHODS: A 30-year-old pregnant woman, who presented at the Center for Medical Genetics and Prenatal Diagnosis of Shandong Maternal and Child Health Care Hospital on November 16, 2023, was enrolled. Clinical data of the pedigree were collected, and peripheral blood samples from the parents and amniotic fluid samples from the two fetuses were obtained for genomic DNA extraction. Whole exome sequencing (WES) was performed on both fetuses, followed by Sanger sequencing for familial validation and pathogenicity analysis of candidate variants. Chromosomal karyotyping of the parents was conducted to quantify the proportion of premature chromatid separation (PCS). This study was approved by the Medical Ethics Committee of Shandong Maternal and Child Health Care Hospital (Ethics No. 2024-034). RESULTS: Both fetuses exhibited structural brain anomalies and developmental delays during the second trimester. Amniocyte karyotyping revealed low-level mosaic aneuploidy involving multiple chromosomes, while chromosomal microarray analysis (CMA) showed no abnormalities. Pregnancy termination was performed for fetus 1. WES identified compound heterozygous variants in BUB1B, i.e., c.2363_2364del (p.S788Cfs*29) and ss804270619: G>A, in both fetuses. Sanger sequencing confirmed paternal inheritance of c.2363_2364del and maternal inheritance of ss804270619:G>A. According to the American College of Medical Genetics and Genomics (ACMG) and Clinical Genome Resource (ClinGen) Standards and Guidelines for the Interpretation of Sequence Variants, the c.2363_2364del variant was classified as likely pathogenic (PVS1 + PM2_Supporting). Parental karyotyping demonstrated PCS traits, with a higher proportion of abnormal metaphases in the father. CONCLUSION The compound heterozygous variants c.2363_2364del (p.S788Cfs*29) and ss804270619: G>A in BUB1B may constitute the genetic etiology of the two MVA fetuses in this pedigree.
