Background: and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture. Methods: A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture. Results: The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05). Conclusion The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

Objective To investigate the efficacy and safety of a new type of self-made bone drill applied to percutaneous transforaminal endoscopic discectomy for L5/S1 intervertebral disc herniation.Methods The clinical data of 52 patients with L5/S1 intervertebral disc herniation admitted to our hospital were retrospectively analyzed.All patients underwent percutaneous transforaminal endoscopic discectomy,with a new type of self-made bone drill for foraminoplasty during the surgery.The surgical conditions and occurrence of complications were recorded.The pain of patients before surgery,3 days after surgery,3 months after surgery,6 months after surgery,and 1 year after surgery was assessed by visual analogue scale(VAS);and the neurological function improvement before and after surgery was evaluated by Oswestry disability index(ODI).Results All patients underwent successful surgery without serious complications or recurrence after surgery.The VAS and ODI scores of patients 3 days,3 months,6 months,and 1 year after surgery were significantly lower than those before surgery(P<0.05).Conclusion The self-made new bone drill can significantly improve the efficiency of foraminoplasty and ensure surgical safety,with satisfactory early clinical effect.

Objective:To explore mechanism of regulation of proliferation,migration,invasion and expressions of immune factors of ovarian cancer SKOV3 cells by circSKA3/miR-3163/disintegrin-metalloproteinase 9(ADAM9)gene axis.Methods:qRT-PCR was used to detect circSKA3 and miR-3163 expressions in ovarian cancer tissues and paracancerous tissues.Western blot was used to detect ADAM9 protein level in tissues.SKOV3 cells were selected for cell experiment in vitro,and divided into sh-NC group,sh-circSKA3 group,miR-NC group,miR-3163 group,sh-circSKA3+anti-miR-3163 group,sh-circSKA3+pcDNA-ADAM9 group.circSKA3 and miR-3163 expressions in SKOV3 cells were detected by qRT-PCR.CCK-8,scratch test and Transwell were used to detect cell proliferation activity,migration and invasion ability.ELISA was used to detect expressions of TNF-α,IL-6 and IL-10.Double luciferase report experiment verified targeting relationship between circSKA3 with miR-3163,miR-3163 and ADAM9.Western blot was used to detect levels of ADAM9,matrix metalloproteinase-2(MMP-2)and MMP-9 in SKOV3 cells.Results:Com-pared with paracancerous tissues,circ-SKA3 and ADAM9 expressions were increased,and miR-3163 expression was decreased in ovarian cancer tissues(P<0.05).Compared with sh-NC group/miR-NC group,sh-circSKA3 group/miR-3163 group showed decreased cell proliferative activity and healing rate,decreased number of invasive cells,MMP-2,MMP-9 proteins and TNF-α and IL-6 expres-sions were decreased,expression of IL-10 was increased(P<0.05).circSKA3 could targeting regulate expression of miR-3163,and miR-3163 could targeting bind to ADAM9(P<0.05).Compared with sh-circSKA3 group,cell proliferation activity and scratch healing rate in sh-circSKA3+anti-miR-3163 and sh-circSKA3+pcDNA-ADAM9 groups were increased,number of invasive cells was in-creased,MMP-2,MMP-9 protein and TNF-α,IL-6 expressions were increased,while expression of IL-10 was decreased(P<0.05).Conclusion:Silencing circSKA3 expression can reduce expression of ADAM9 by up-regulating miR-3163 expression,inhibit ovarian cancer cell proliferation,migration and invasion,and regulate immune factor expression.

Objective To explore the biological effect of transcription factor B1,mitochondrial(TFB1M)on hepatocellular carcinoma(HCC)cells,and to explore the molecular mechanism of its regulation on malignant metastasis of HCC.Methods The expression level of TFB1M in liver cancer and its relationship with clinical characteristics of patients with HCC was analyzed based on TCGA-LIHC and GEO databases.Based on the median expression level of TFB1M,the TCGA-LIHC samples were divided into low expression group of TFB1 M(n=170)and high expression group of TFB1M(n=170),and GSEA was used for gene set enrichment analysis.The overexpressed TFB1M plasmid was constructed to transfect HepG2 and Huh7 cells.Cell migration and invasion were assessed by scratch healing and Transwell chamber assays.Results The expression of TFB1M was significantly decreased in HCC,and the expression of TFB1M was related with gender in HCC.The results of GSEA analysis indicated that the low expression of TFB1M might be related to liver cancer subclass proliferation up gene set,stem cell hepatocellular carcinoma gene set,and extracellular matrix assembly gene set in HCC.Overexpression of TFB1M remarkably attenuated the migration and invasion activity of HCC cells.Conclusions The expression of TFB1M was significantly decreased in HCC,and overexpression of TFB1M could attenuated the migration and invasion activity of HCC cells.

Objective:To investigate the effects of PD-1 monoclonal antibody therapy on the peripheral and local immune microenvironment of patients with microsatellite instability-high(MSI-H)rectal cancer.Methods:Samples of peripheral blood and tumor biopsy were collected from a patient with MSI-H rectal cancer before and after PD-1 monoclonal antibody treatment.The samples were dissociated into single-cell suspensions using a combination of enzymatic and mechanical methods.Immune-related marker expression on peripheral and tumor-infiltrating im-mune cells was analyzed using single-cell mass cytometry(CyTOF).Results:According to the results of CyTOF analysis,CD45+immune cells in the peripheral blood and tumor tissues were categorized into 39 and 34 cell subsets,respectively,before and after PD-1 monoclonal antibody treatment(the correlation is unclear and ambiguous).After PD-1 monoclonal antibody treatment,differences were observed in the relative abundance of immune cell subsets:B cells significantly decreased in the peripheral blood,while B cells and γδT cells significantly increased in the tumor tissue;neutrophils significantly decreased,and the proportion of CD4+TEM cells in T cell subsets significantly increased,whereas CD4+Treg cells significantly decreased.Additionally,there were differences in the expression of immune-related markers in multiple immune cell subsets in both peripheral blood and tumor tissues,with CCR6 showing a significant increase in expression across all subsets,while ICOS and PD-1 expressions in T cell subsets were significantly reduced(the specific tissues for these cells or factors are unclear).Conclusion:After PD-1 monoclonal antibody treatment in MSI-H rectal cancer,changes occurred in the composition of immune cells and the expression of immune-related markers in both peripheral blood and tumor tissues.This study reveals the dynamic adjustment of the immune microenvironment and provides important evidence for understanding the therapeutic mechanism of PD-1 monoclonal antibodies.
