Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APCmin/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.

ObjectiveTo compare the effects of different doses and withdrawal time of 4-vinylcyclohexene diepoxide (VCD) on the reproductive endocrine levels of female rats, and to explore the effective, stable, and safe dosage of VCD for constructing a premature ovarian insufficiency (POI) rat model. MethodSD rats with regular estrous cycles were randomly divided into three groups: blank group, low-dose VCD group (80 mg·kg-1·d-1), and high-dose VCD group (160 mg·kg-1·d-1), with 24 rats in each group. After drug intervention, samples were collected on the 15th day (D15) and the 45th day (D45) after intervention. The general condition, rate of estrous cycle disturbance, serum hormone levels, ovarian histomorphology, follicle count, pregnancy outcome, and the protein and mRNA expression of transforming growth factor (TGF)-β and Smad2/3 were assessed. ResultCompared with the blank group, the low-dose VCD group showed no significant differences in the rate of estrous cycle disturbance or serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels. Ovarian tissue was damaged. Specifically, the number of primordial and primary follicles decreased on D15 (P<0.01), and the number of secondary follicles (P<0.01) and antral follicles (P<0.05) further decreased on D45. The litter number decreased on D15 (P<0.05), but there was no significant difference on D45. Furthermore, TGF-β protein levels increased on D15 (P<0.05) and D45 (P<0.01). The Smad2/3 levels increased on D45 (P<0.01), and TGF-β and Smad2/3 mRNA levels increased on D45 (P<0.05). Compared with the results in the blank group, the disturbance rate of the estrous cycle increased on D45 in the high-dose VCD group (P<0.01). The serum of FSH and LH increased (P<0.01), while E2 decreased (P<0.05). Ovarian tissue was damaged, and the downward trend of follicles at all levels was similar to that in the low-dose VCD group. The litter number significantly decreased on D15 and D45. TGF-β and Smad2/3 protein levels increased (P<0.05,P<0.01), and TGF-β mRNA increased on D45 (P<0.05). ConclusionHigh-dose VCD is an ideal method for constructing a POI rat model, being effective, stable, and safe.

Objectives:To compare the diagnostic efficacy of non-ST-segment elevation myocardial infarction (NSTEMI) and the predictive value for major adverse cardiovascular events (MACE) of the 0/3-hour algorithm for high-sensitivity cardiac troponin (hs-cTn) recommended by the 2015 European Society of Cardiology (ESC) guidelines for the management of non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and the 2021 "Chinese Expert Consensus on Laboratory Testing and Clinical Application of Cardiac Troponin" in suspected acute coronary syndrome (ACS) patients in the Chinese population. Methods:This is a multicenter prospective observational study,including 1527 patients with suspected ACS from three clinical centers from January 2017 to September 2020.Plasma hs-cTnI levels were measured using the ARCHITECT assay at the time of presentation and 3 hours later in patients with suspected ACS (test determination).Clinical judgment (independent clinical judgment by cardiac experts,independent of the test results) was used as the gold standard to compare the sensitivity,specificity,and consistency of the two diagnostic algorithms,and to analyze their predictive value for MACE at 30 days and 180 days.MACE in this study was defined as a composite event of cardiovascular death,myocardial infarction,and unplanned coronary revascularization. Results:According to clinical judgment,there were 400 patients with NSTEMI and 1127 patients without NSTEMI.The 0/3-hour algorithm recommended by the 2021 Chinese Expert Consensus showed higher sensitivity in diagnosing NSTEMI than the 2015 ESC guidelines (91.50%[95% CI:88.32%-94.04%]vs.87.75%[95% CI:84.13%-90.80%]),but slightly lower specificity (93.88%[95% CI:92.32%-95.21%]vs.95.56%[95% CI:94.19%-96.69%]),with both differences being statistically significant (both P<0.001).In the follow-up at 30 days and 180 days,the incidence of MACE in patients diagnosed with NSTEMI by both algorithms was higher than in those without NSTEMI (P<0.001).The incidence of MACE at 30 days and 180 days for the group excluded from the diagnosis of NSTEMI by 2015 ESC guidelines was 0.19% and 1.120%,respectively,and for the NSTEMI group was 2.89% and 3.68%,respectively;for the group excluded from NSTEMI by the 2021 Chinese Expert Consensus,the incidence was 0.096% and 0.770%,respectively,and for the NSTEMI group was 2.91% and 4.36%,respectively.Cox analysis showed that the HR ratio for MACE at 180 days in the NSTEMI group diagnosed by both algorithms was 3.418 and 5.892,respectively,significantly higher than the group excluded from NSTEMI. Conclusions:The 0/3-hour algorithm recommended by the 2021 Chinese Expert Consensus has superior diagnostic sensitivity compared to the 2015 ESC NSTE-ACS guidelines,at the cost of slightly lower specificity.Both algorithms can effectively predict MACE within 180 days,but based on the data from this study,the algorithm recommended by the 2021 Chinese Expert Consensus is more sensitive in predicting the risk of MACE,and patients excluded from the diagnosis of NSTEMI by this method have a lower incidence of MACE,suggesting that its application in clinical practice may be more helpful in terms of long-term safe management of patients.

10.A case report of intramyocardial dissecting hematoma: a challenging diagnosis
World Journal of Emergency Medicine 2023;14(5):405-407
Intramyocardial dissecting hematoma (IDH) is an uncommon complication of myocardial infarction that can potentially lead to cardiac rupture.[1] Two distinguishable types of cardiac rupture have been identified: a simple tear, which is the most common case and is characterized by a lineal or tortuous tear along the myocardial wall, and complex hemorrhagic dissection. IDH is generally classified as complex hemorrhagic dissection, in which blood infiltrates into the myocardial wall.[2] IDH is characterized by a serpiginous tract within the myocardium, which is also known as subepicardial aneurysm. The mechanisms of IDH are multifactorial and contribute to the rupture of intramyocardial vessels, diminished tensile strength of the infarcted myocardium, abrupt increases in perfusion pressure during the perfusion phase, or in rare cases, iatrogenesis.[3] Furthermore, the anatomical substrate of IDH is the spiral helical structure of the heart that favors hemorrhage spreading along the spiral myocardial fibers.[4] IDH is often a challenging diagnosis and prone to misdiagnosis because of its rarity and various clinical presentations. Here, we report a patient with IDH.
