Colorectal cancer(CRC) is a common malignant tumor worldwide. Due to the treatment intolerance and side effects, CRC rank the top among various cancers regarding the incidence and mortality rates. Therefore, exploring new therapies is of great significance for the treatment of CRC. Aerobic glycolysis(AEG) plays an important role in the microenvironment formation, proliferation, metastasis, and recurrence of CRC and other tumor cells. It has been confirmed that intervening in the AEG pathway can effectively curb CRC. The active ingredients and compound prescriptions of traditional Chinese medicine(TCM) can effectively inhibit the proliferation, metastasis, and drug resistance and regulate the apoptosis of tumor cells by modulating AEG-associated transport proteins [eg, glucose transporters(GLUT)], key enzymes [hexokinase(HK) and phosphofructokinase(PFK)], key genes [hypoxia-inducible factor 1(HIF-1) and oncogene(c-Myc)], and signaling pathways(MET/PI3K/Akt/mTOR). Accordingly, they can treat CRC, reduce the recurrence, and improve the prognosis of CRC. Although AEG plays a key role in the development and progression of CRC, the specific mechanisms are not yet fully understood. Therefore, this article delves into the intrinsic connection of the targets and mechanisms of the AEG pathway with CRC from the perspective of tumor cell glycolysis and explores how active ingredients(oxymatrine, kaempferol, and dioscin) and compound prescriptions(Quxie Capsules, Jiedu Sangen Decoction, and Xianlian Jiedu Prescription) of TCM treat CRC by intervening in the AEG pathway. Additionally, this article explores the shortcomings in the current research, aiming to provide reliable targets and a theoretical basis for treating CRC with TCM.

Prostate cancer(PCa) is a common malignant tumor among elderly men, with high incidence and mortality rates worldwide, posing a serious threat to human health. Traditional treatments face limitations, highlighting the urgent need for novel therapeutic strategies. Recent studies on the regulatory mechanisms of micro ribonucleic acid(microRNA, miRNA) in tumor development has identified miRNA as new targets for PCa diagnosis and treatment. Traditional Chinese medicine(TCM), with its multi-mechanism, multi-target, and multi-pathway regulatory properties, shows promising potential in miRNA-based PCa therapy. This review summarized recent findings on miRNA' roles in PCa and research progress of TCM intervention and found that a variety of miRNA played important regulatory roles in cell differentiation, proliferation, apoptosis, invasion, metastasis, immune microenvironment, and drug resistance, and their potential as biomarkers for PCa diagnosis, prognosis, and therapy, indicating the potential to be a biomarker for the diagnosis, prognosis evaluation, and treatment of PCa. The review concluded that the active components of TCM(terpenoids, flavonoids, alkaloids, and others) and compounds(Yishen Tonglong Decoction, Shenhu Decoction, Zhoushi Qiling Decoction, Fuzheng Yiliu Decoction, and Qilan Formula) could regulate the expression of their downstream target genes by acting on specific miRNA and affect the above biological behaviors of PCa cells, thus playing a role in the treatment of PCa. This review aims to provide a theoretical basis for miRNA as potential biomarkers and therapeutic targets for PCa and suggest new avenues for further development of targeted therapy strategies against miRNA.

Objective:To investigate the impact of flow diverter (FD) malapposition at the aneurysm neck on clinical outcomes and complications of intracranial aneurysms, and identify the influencing factors for intraoperative FD malapposition.Methods:A retrospective study was performed; 153 patients with unruptured saccular aneurysms at the C4-C7 segments of the internal carotid artery accepted single FD implantation at Department of Interventional Radiology, First Affiliated Hospital of Zhengzhou University from June 2022 to March 2024 were chosen. Intraoperative high-resolution C-arm CT was utilized to assess FD apposition at the aneurysm neck. (1) Based on FD apposition at the aneurysm neck as shown, these 153 patients were divided into a malapposition group ( n=23, including 16 patients with malapposition being identified as residual malapposition after intraoperative corrective measures such as microwire massage and 7 patients with malapposition being newly detected in this study) and a complete apposition group ( n=130). Perioperative and follow-up complications were recorded. Clinical outcomes were assessed using modified Rankin Scale (mRS) at the final follow-up (mRS score of 0-2 as favorable outcome), and angiographic outcomes were evaluated by DSA at the final follow-up. Differences in clinical and angiographic outcomes and complication rate were compared between the malapposition group and complete apposition group. (2) Based on FD apposition at the aneurysm neck as shown, these 153 patients were divided into an intraoperative malapposition group ( n=74, including 67 patients with malapposition being detected during surgery and 7 patients with malapposition being newly detected in this study) and an intraoperative complete apposition group ( n=79). Univariate analysis was performed to compare the clinical variables between the intraoperative malapposition group and intraoperative complete apposition group; multivariate Logistic regression was further employed to identify the independent influencing factors for FD malapposition at the aneurysm neck. Results:(1) Four patients (all from the malapposition group) developed perioperative acute in-stent thrombosis. Nine patients experienced ischemic or hemorrhagic stroke during the follow-up, including 6 from the malapposition group and 3 from the complete apposition group; the complication rate in the malapposition group (6/23, 26.1%) was significantly higher than that in the complete apposition group (3/130, 2.3%) during the follow-up ( P<0.05). At the final follow-up, 2 patients (both from the malapposition group) had poor clinical outcome, while the remaining 151 patients had favorable outcome. Proportion of patients with favorable outcome between the two groups was statistically different (91.3%[21/23] vs. 100.0%[130/130], P<0.05). Delayed occlusion was detected in 46 patients (12 from the malapposition group and 34 from the complete apposition group) at the final angiographic follow-up. FD restenosis/re-occlusion was noted in 10 patients, including 6 from the malapposition group and 4 from the complete apposition group. Significant difference in delayed occlusion rate (52.2%[12/23] vs. 26.2%[34/130]) and long-term in-stent stenosis/occlusion rate (26.1%[6/23] vs. 3.1%[4/130]) was observed between the two groups ( P<0.05). (2) Significant difference in aneurysm neck diameter, FD angulation, parent artery stenosis, parent artery diameter ratio>1.2, and presence of branching vessels at the FD implantation site was noted between the intraoperative complete apposition group and intraoperative malapposition group ( P<0.05). Multivariate Logistic regression indicated that aneurysm neck diameter ( OR=1.431, 95% CI: 1.096-1.868, P=0.008), parent artery diameter ratio>1.2 ( OR=2.199, 95% CI: 1.083-4.463, P=0.029), and FD angulation ( OR=1.019, 95% CI: 1.002-1.036, P=0.027) were independent influencing factors for FD malapposition at the aneurysm neck. Conclusion:In FD implantation for intracranial aneurysms, FD malapposition at the aneurysm neck adversely affects delayed occlusion rate and complication rate; aneurysms with wider aneurysm neck diameter, parent artery diameter ratio>1.2, and greater FD angulation are trend to have FD malapposition at the aneurysm neck.

Objective To evaluate the safety and efficacy of valve-in-valve transcatheter mitral valve replacement(ViV-TMVR)in patients with bioprosthetic valve degeneration who are at high surgical risk.Methods This study is a multi-center,retrospective cohort analysis of 20 consecutive patients who underwent transseptal ViV-TMVR using the Edwards SAPIEN 3 transcatheter heart valve(THV).The primary endpoints include technical success and procedural success,both defined according to the Mitral Valve Academic Research Consortium(MVARC)criteria,as well as mortality and functional change assessed based on New York Heart Association(NYHA)classification at 30-days and six months post-procedure.Clinical follow-up assessments are conducted at 30-days and six months.Results From February 2021 to October 2022,a total of 20 patients with symptoms of bioprosthetic valve degeneration were enrolled across nine sites in China.The patients had a mean age of(73.5±5.5)years,with 85.0％being females and 70.0％classified as NYHA class Ⅲ/Ⅳ.The study achieved a 100.0％technical success rate and a 90.0％procedural success rate finally.All patients remained alive during the 30-day follow-up period.However,six months post-intervention,two patients(10.0％)were re-hospitalized due to heart failure,and sadly,one of them(5.0％)died.None of the patients reported any adverse events related to ViV-TMVR during the follow-up period.Notably,there was a significant improvement in NYHA class compared to baseline(P=0.0004)at six-month follow-ups.Conclusions The transseptal ViV-TMVR technique proved to be highly successful and was associated with significant improvement in NYHA class function.These findings strongly suggest that it serves as a safe and efficient treatment alternative for high-risk patients suffering from bioprosthetic valve degeneration.
