OBJECTIVE To assess the bleeding risk signals associated with the concomitant use of direct oral anticoagulants (DOACs) and triazole antifungals, and to provide pharmacovigilance evidence for the safety evaluation and monitoring of combined clinical use. METHODS Adverse event reports involving the concomitant use of DOACs and triazole antifungals were extracted from the US FDA Adverse Event Reporting System (FAERS) from the first quarter of 2004 to the third quarter of 2025. Nine bleeding-related preferred terms (PTs) were selected. The Ω shrinkage measure, additive model, multiplicative model, and combined risk ratio method were employed to detect drug-drug interaction signals. The strength of positive signals was further analyzed based on the Ω shrinkage measure. RESULTS A total of 790 adverse event reports involving the concomitant use of DOACs and triazole antifungals were included, among which 229 reports involved nine bleeding-related PTs. A total of 13 signals were consistently identified as posit ive by all four methods. These signals involved six drug combinations: apixaban-fluconazole, apixaban-posaconazole, rivaroxaban-itraconazole, dabigatran etexilate-fluconazole, apixaban-voriconazole, and dabigatran etexilate-itraconazole. The Ω shrinkage measure showed that the apixaban-posaconazole combination exhibited stronger signals for bleeding ( Ω =2.73, Ω 025 =2.05) and hemoptysis ( Ω =2.17, Ω 025 =0.83); the apixaban-fluconazole combination exhibited stronger signals for hematoma ( Ω =2.30, Ω 025 =1.47) and hematuria ( Ω =1.71, Ω 025 =0.74); the rivaroxaban-itraconazole combination exhibited stronger signals for epistaxis ( Ω =2.01, Ω 025 =0.90) and hematoma ( Ω =1.93, Ω 025 =0.42); no positive Ω signals were observed for intracranial hemorrhage or upper gastrointestinal hemorrhage. CONCLUSION S This study suggests that the concomitant use of DOACs and triazole antifungals may increase the risk of bleeding-related events, with differences in signal strength and signal distribution across various drug combinations. In clinical practice, particular attention should be paid to the concomitant use of apixaban or rivaroxaban with strong cytochrome P450 3A4 or P-glycoprotein inhibitors such as posaconazole and itraconazole. For other DOAC-triazole antifungal combinations, close monitoring for bleeding-related manifestations and timely adjustment of anticoagulation or antifungal regimens are also warranted.

ObjectiveTo analyze the effects of the progestin-primed ovarian stimulation (PPOS) protocol on embryo euploidy rate and clinical pregnancy outcomes in infertile patients. MethodsWomen who underwent Preimplantation genetic testing for aneuploidy (PGT-A) cycles were selected as study participants (a total of 656 cycles and 3 081 blastocysts). Participants were divided into two age groups (≤35 years and >35 years) and further stratified by ovarian stimulation protocol: the Progestin-Primed Ovarian Stimulation (PPOS) group (n=48 and 60, respectively), the Luteal Phase Long Protocol (LP) group (n=160 and 57, respectively), and the Gonadotropin-Releasing Hormone Antagonist Protocol (AP) group (n=220 and 111, respectively). Baseline characteristics, ovarian stimulation outcomes, and embryo development parameters were compared among the three protocols within each age group. Additionally, clinical pregnancy outcomes of the first frozen embryo transfer (FET) cycle were compared. The primary outcome measure was the embryo euploidy rate. Results① In the ≤35 years age group, baseline follicle-stimulating hormone (bFSH) levels were significantly higher in the PPOS group compared to the LP and AP groups, and the bFSH/bLH ratio was significantly higher in the PPOS group than in the AP group (P < 0.05). In the >35 years age group, bFSH levels in both the PPOS and AP groups were significantly higher than in the LP group (P < 0.05).② In the ≤35 years group, there were no significant differences in the rates of metaphase II (MII) oocytes, 2-pronuclei (2 PN) zygotes, cleavage, 2 PN cleavage, blastocyst formation, high-quality embryos, or embryo euploidy between the PPOS group and either the LP or AP groups. However, the PPOS group showed significantly lower values for the following parameters compared to the other two groups: total oocytes retrieved, number of MII oocytes, number of 2 PN zygotes, number of cleaved embryos, number of 2 PN cleaved embryos, number of blastocysts formed, number of high-quality embryos, number of high-grade blastocysts, number of transferable embryos, number of cryopreserved embryos, number of biopsied blastocysts, number of euploid embryos, and the rate of obtaining at least one euploid embryo. In the >35 years group, no significant differences were observed among the PPOS, LP, and AP groups in the rates of MII oocytes, 2 PN cleavage, blastocyst formation, or in the number of euploid embryos, euploidy rate, and the rate of obtaining at least one euploid embryo. However, the PPOS group had significantly lower numbers of total oocytes retrieved, MII oocytes, 2 PN zygotes, cleaved embryos, 2 PN cleaved embryos, blastocysts formed, transferable embryos, and cryopreserved embryos compared to the LP group (P<0.05). The high-quality embryo rate was significantly lower in the PPOS group than in the AP group (P<0.05). The numbers of high-quality embryos, high-grade blastocysts, and biopsied blastocysts were significantly lower in the PPOS group than in both the LP and AP groups (P<0.05). Notably, the 2 PN fertilization rate was significantly higher in the PPOS group than in the AP group, and the cleavage rate was significantly higher in the PPOS group than in both the LP and AP groups (P<0.05).③ No significant differences were found among the three groups in the biochemical pregnancy rate, clinical pregnancy rate, live birth rate, early miscarriage rate, and late miscarriage rate following the first FET cycle. ConclusionCompared to the other two protocols, the PPOS protocol does not significantly affect embryo euploidy or clinical pregnancy rates. However, in freeze-all cycles with PGT-A, the PPOS protocol does not reduce the rate of chromosomally normal embryos but may decrease the total number of available embryos. It may not be the optimal choice for younger women, but it can be considered as a viable option for women of advanced maternal age.

N-acetylcysteine (NAC) is an acetylated derivative of cysteine that exerts multiple biological activities, including antioxidant, anti-inflammatory, antimicrobial, and mucolytic effects, and has been widely used clinically for the treatment of respiratory diseases. NAC not only directly scavenges reactive oxygen and nitrogen species and strengthens endogenous antioxidant defenses by promoting glutathione synthesis but also modulates immune responses and suppresses inflammatory signaling pathways such as nuclear factor kappa B, thereby attenuating inflammation. In addition, NAC disrupts biofilm architecture by cleaving disulfide bonds, reduces microbial virulence, and enhances the penetration of antimicrobial agents, conferring robust antibacterial and antibiofilm activities. The initiation and progression of oral diseases—including dental caries, periodontal disease, pulpal-periapical disease, and infectious oral mucositis—are closely associated with pathogenic infection, oxidative stress, and dysregulated immune-inflammatory responses. NAC can inhibit Streptococcus mutans adhesion and biofilm formation, thereby reducing cariogenic virulence; mitigate periodontal tissue destruction through antimicrobial, anti-inflammatory, and antioxidant actions, and may modulate bone metabolism; enhance the clearance of Enterococcus faecalis biofilms and improve the efficacy of antimicrobial therapy; and inhibit the growth and hyphal formation of Candida albicans. Collectively, NAC is emerging as a promising agent for the prevention and treatment of oral infectious diseases. This review systematically summarizes the major bioactivities of NAC, its mechanistic actions in oral infectious diseases, and its therapeutic prospects, with the aim of providing a theoretical basis for future basic and clinical investigations.

ObjectiveTo focused on patients with unexplained repeated implantation failure (URIF) and compare the clinical efficacy of different administration routes of granulocyte colony-stimulating factor (G-CSF) in patients undergoing frozen-thawed embryo transfer cycles. MethodsA retrospective case-control study was conducted. A total of 187 patients with URIF who received medical treatment were enrolled in this study. According to whether G-CSF was used on the day of endometrial transformation and its administration route in frozen-thawed embryo transfer cycles, the patients were divided into three groups: control group (without G-CSF, n=71), subcutaneous injection group (subcutaneous G-CSF, n=72), and intrauterine infusion group (intrauterine G-CSF infusion, n=44). The pregnancy outcomes among the three groups were compared, and Logistic regression analysis was performed. ResultsThere were significant differences in biochemical pregnancy rates among the three groups (P<0.05), indicating statistical significance in the overall comparison. In terms of numerical trend, the biochemical pregnancy rate was in the order: subcutaneous injection group > intrauterine infusion group > control group. Further pairwise comparison showed that only the difference between the subcutaneous injection group and the control group was statistically significant (P<0.017), while no significant differences were found between the other groups (P>0.017). The overall comparison of early miscarriage rates among the three groups also showed a significant difference (P<0.05), indicating a statistically significant difference in the distribution among the groups. The numerical trend was: intrauterine perfusion group > subcutaneous injection group > control group. Pairwise comparison results showed that only the difference between the intrauterine perfusion group and the control group was statistically significant (P<0.017), while there was no statistically significant difference between any other two groups (P>0.017).Multivariate Logistic regression analysis showed that endometrial thickness on the day of transformation, number of transferred embryos, and subcutaneous G-CSF injection were independent factors associated with an increased biochemical pregnancy rate, where as age was an independent factor for a decreased biochemical pregnancy rate. For clinical pregnancy outcome, endometrial thickness on the day of transformation, number of transferred embryos, and subcutaneous G-CSF injection were also independent factors for an increased clinical pregnancy rate, while BMI was an independent factor for a decreased clinical pregnancy rate. ConclusionSubcutaneous injection of G-CSF only improved the biochemical pregnancy rate in URIF patients. Multivariate Logistic regression analysis showed that subcutaneous G-CSF injection was a favorable factor for clinical pregnancy rate in URIF patients; however, no significant improvement in clinical pregnancy rate was observed among the three groups. Both the comparison of pregnancy outcomes and the results of multivariate logistic regression analysis indicates that intrauterine perfusion of G-CSF has no significant therapeutic effect in the treatment of patients with URIF.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

OBJECTIVES:
To study the molecular mechanisms of LDH-loaded si-NEAT1 for regulating paclitaxel resistance and tumor-associated macrophage (TAM) polarization in breast cancer.
METHODS:
qRT-PCR and Western blotting were used to detect the expression of lncRNA NEAT1, miR-133b, and PD-L1 in breast cancer SKBR3 cells and paclitaxel-resistant SKBR3 cells (SKBR3-PR). The effects of transfection with si-NEAT1 and miR-133b mimics on MRP, MCRP and PD-L1 expressions and cell proliferation, migration and apoptosis were investigated using qRT-PCR, Western blotting, scratch and Transwell assays, and flow cytometry. Rescue experiments were conducted using si-NEAT1 and miR-133b inhibitor. Human THP-1 macrophages were cultured in the presence of conditioned media (CM) derived from SKBR3 and SKBR3-PR cells with or with si-NEAT1 transfection for comparison of IL-4-induced macrophage polarization by detecting the surface markers. LDH@si-NEAT1 nanocarriers were constructed, and their effects on MRP, MCRP and PD-L1 expressions and cell behaviors of the tumor cells were examined. THP-1 cells were treated with the CM from LDH@si-NEAT1-treated tumor cells, and the changes in their polarization were assessed.
RESULTS:
SKBR3-PR cells showered significantly upregulated NEAT1 and PD-L1 expressions and lowered miR-133b expression as compared with their parental cells. Transfection with si-NEAT1 and miR-133b mimics inhibited viability, promoted apoptosis and enhanced MRP and BCRP expressions in SKBR3-PR cells. NEAT1 knockdown obvious upregulated miR-133b and downregulated PD-L1, MRP and BCRP expressions. The CM from SKBR3-PR cells obviously promoted M2 polarization of THP-1 macrophages, which was significantly inhibited by CM from si-NEAT1-transfected cells. Treatment with LDH@si-NEAT1 effectively inhibited migration and invasion, promoted apoptosis, and reduced MRP, BCRP and PD-L1 expressions in the tumor cells. The CM from LDH@si-NEAT1-treated SKBR3-PR cells significantly downregulated Arg-1, CD163, IL-10, and PD-L1 and upregulated miR-133b expression in THP-1 macrophages.
CONCLUSIONS
LDH@si-NEAT1 reduces paclitaxel resistance of breast cancer cells and inhibits TAM polarization by targeting the miR-133b/PD-L1 axis.

BACKGROUND:
T-cell lymphoblastic lymphoma/acute lymphoblastic leukemia (T-LBL/ALL) is an aggressive form of hematological malignancy associated with poor prognosis in adult patients. Histone deacetylases (HDACs) are aberrantly expressed in T-LBL/ALL and are considered potential therapeutic targets. Here, we investigated the antitumor effect of a novel HDAC inhibitor, chidamide, on T-LBL/ALL.
METHODS:
HDAC1, HDAC2 and HDAC3 levels in T-LBL/ALL cell lines and patient samples were compared with those in normal controls. Flow cytometry, transmission electron microscopy, and lactate dehydrogenase release assays were conducted in Jurkat and MOLT-4 cells to assess apoptosis and pyroptosis. A specific forkhead box O1 (FOXO1) inhibitor was used to rescue pyroptosis and upregulated gasdermin E (GSDME) expression caused by chidamide treatment. The role of the FOXO1 transcription factor was evaluated by dual-luciferase reporter and chromatin immunoprecipitation assays. The efficacy of chidamide in vivo was evaluated in a xenograft mouse.
RESULTS:
The expression of HDAC1, HDAC2 and HDAC3 was significantly upregulated in T-LBL/ALL. Cell viability was obviously inhibited after chidamide treatment. Pyroptosis, characterized by cell swelling, pore formation on the plasma membrane and lactate dehydrogenase leakage, was identified as a new mechanism of chidamide treatment. Chidamide triggered pyroptosis through caspase 3 activation and GSDME transcriptional upregulation. Chromatin immunoprecipitation assays confirmed that chidamide led to the increased transcription of GSDME through a more relaxed chromatin structure at the promoter and the upregulation of FOXO1 expression. Moreover, we identified the therapeutic effect of chidamide in vivo .
CONCLUSIONS
This study suggested that chidamide exerts an antitumor effect on T-LBL/ALL and promotes a more inflammatory form of cell death via the FOXO1/GSDME axis, which provides a novel choice of targeted therapy for patients with T-LBL/ALL.
