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.

OBJECTIVE To investigate the effect and mechanism of Jingangteng capsules in the treatment of non-alcoholic fatty liver disease （NAFLD）. METHODS Thirty-two SD rats were randomly divided into normal group and modeling group. The modeling group was fed a high-fat diet to establish a NAFLD model. The successfully modeled rats were then randomly divided into model group， atorvastatin group[positive control， 2 mg/（kg·d）]， and Jingangteng capsules low- and high-dose groups [0.63 and 2.52 mg/（kg·d）]， with 6 rats in each group. The pathological changes of the liver were observed by hematoxylin-eosin staining and oil red O staining. Enzyme-linked immunosorbent assay was performed to determine the serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， alanine transaminase （ALT）， aspartate transaminase （AST）， tumour necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， IL-6， IL-18. 16S rDNA amplicon sequencing and metabolomics techniques were applied to explore the effects of Jingangteng capsules on gut microbiota and metabolisms in NAFLD rats. Based on the E-mail：591146765@qq.com metabolomics results， Western blot analysis was performed to detect proteins related to the nuclear factor kappa-B （NF-κB）/NOD-like receptor family protein 3 （NLRP3） signaling pathway in the livers of NAFLD rats. RESULTS The experimental results showed that Jingangteng capsules could significantly reduce the serum levels of TG， TC， LDL-C， AST， ALT， TNF-α， IL-1β， IL-6， IL-18， while increased the level of HDL-C， and alleviated the hepatic cellular steatosis and inflammatory infiltration in NAFLD rats. They could regulate the gut microbiota disorders in NAFLD rats， significantly increased the relative abundance of Romboutsia and Oscillospira， and significantly decreased the relative abundance of Blautia （P＜0.05）. They also regulated metabolic disorders primarily by affecting secondary bile acid biosynthesis， fatty acid degradation， O-antigen nucleotide sugar biosynthesis， etc. Results of Western blot assay showed that they significantly reduced the phosphorylation levels of NF-κB p65 and NF-κB inhibitor α， and the protein expression levels of NLRP3， caspase-1 and ASC （P＜0.05 or P＜0.01）. CONCLUSIONS Jingangteng capsules could improve inflammation， lipid accumulation and liver injury in NAFLD rats， regulate the disorders of gut microbiota and metabolisms， and inhibit NF-κB/NLRP3 signaling pathway. Their therapeutic effects against NAFLD are mediated through the inhibition of the NF-κB/NLRP3 signaling pathway.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective:To investigate the clinical efficacy of cervical cerclage in singleton pregnancy with different degrees of short cervix.Methods:The clinical data of singleton pregnant women who underwent transvaginal ultrasound examination at 18-24 +6 weeks of gestation and found cervical dilation with cervical length (CL) ≤20 mm, and without history of spontaneous preterm delivery or late abortion in Women′s Hospital, Zhejiang University School of Medicine from January 2021 to September 2023 were collected and retrospectively analyzed. According to the case control matching, 78 pregnant women in the cerclage group and 78 women in the conservative treatment group were finally included. The pregnancy outcomes and neonatal prognosis of the two groups were compared. Meanwhile, the two groups of pregnant women were divided into three subgroups for stratification (CL≤10, 11-15, 16-20 mm). Multivariate logistic regression analysis and Kaplan-Meier curve were used to evaluate the effect of cervical cerclage on pregnancy outcomes in different subgroups. Results:(1) Compared with the conservative treatment group, the gestational age at delivery (median: 36 vs 37 weeks) and the duration of pregnancy extension (median: 90 vs 97 days) in the cerclage group were not significantly prolonged (all P>0.05). There was no significant difference in the cumulative non-delivery rate between the cerclage group and the conservative treatment group ( P=0.143). The rate of neonatal intensive care unit (NICU) admission in the cerclage group was significantly higher than that in the conservative treatment group (46.1% vs 31.2%, P<0.001), but there were no significant differences in other neonatal outcomes between the two groups (all P>0.05). (2) CL 16-20 mm subgroup: compared with the conservative treatment group (28 cases), the cerclage group (18 cases) had a significantly higher rate of preterm birth before 37 weeks of gestation (3.6% vs 6/18, P<0.001) and a significantly lower neonatal birth weight (median: 3 370 vs 2 925 g, P<0.001). There was no significant difference in the cumulative non-delivery rate between the cerclage group and the conservative treatment group ( P=0.168). (3) CL 11-15 mm subgroup: compared with the conservative treatment group (26 cases), the gestational age of delivery in the cerclage group (32 cases) was later (median: 36 and 37 weeks, respectively), and the difference was statistically significant ( P<0.05). The cumulative non-delivery rate in the cerclage group was significantly higher than that in the conservative treatment group ( P=0.001). (4) CL≤10 mm subgroup: compared with the conservative treatment group (24 cases), the pregnant women in the cerclage group (28 cases) had a later gestational age at delivery (median: 34 vs 37 weeks), a longer duration of pregnancy (median: 74 vs 97 days), and a larger newborn birth weight (median: 2 300 vs 3 165 g). The rates of preterm birth before 34 weeks of gestation (45.8% vs 14.3%) and before 37 weeks of gestation (83.3% vs 39.3%) were lower, and the differences were all statistically significant (all P<0.05). The cumulative non-delivery rate of pregnant women in the cerclage group was significantly higher than that in the conservative treatment group ( P<0.001). Conclusion:Cervical cerclage could significantly prolong the gestational weeks and improve the perinatal outcomes for singleton pregnant women with cervical internal orifice dilation and CL≤15 mm without a history of spontaneous preterm delivery or late abortion.

OBJECTIVE: To elucidate how spinal manipulative therapy (SMT) exerts its analgesic effects through regulating brain function in lumbar disc herniation (LDH) patients by utilizing resting-state functional magnetic resonance imaging (rs-fMRI). METHODS: From September 2021 to September 2023, we enrolled LDH patients (LDH group, n=31) and age- and sex-matched healthy controls (HCs, n=28). LDH group underwent rs-fMRI at 2 distinct time points (TPs): prior to the initiation of SMT (TP1) and subsequent to the completion of the SMT sessions (TP2). SMT was administered once every other day for 30 min per session, totally 14 treatment sessions over a span of 4 weeks. HCs did not receive SMT treatment and underwent only one fMRI scan. Additionally, participants in LDH group completed clinical questionnaires on pain using the Visual Analog Scale (VAS) and the Japanese Orthopedic Association (JOA) score, whereas HCs did not undergo clinical scale assessments. The effects on the brain were jointly characterized using the amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo). Correlation analyses were conducted between specific brain regions and clinical scales. RESULTS: Following SMT treatment, pain symptoms in LDH patients were notably alleviated and accompanied by evident activation of effects in the brain. In comparison to TP1, TP2 exhibited the most significant increase in ALFF values for Temporal_Sup_R and the most notable decrease in ALFF values for Paracentral_Lobule_L (voxelwise P<0.005; clusters >30; FDR correction). Additionally, the most substantial enhancement in ReHo values was observed for the Cuneus_R, while the most prominent reduction was noted for the Olfactory_R (voxelwise P<0.005; clusters >30; FDR correction). Moreover, a comparative analysis revealed that, in contrast to HCs, LDH patients at TP1 exhibited the most significant increase in ALFF values for Temporal_Pole_Sup_L and the most notable decrease in ALFF values for Frontal_Mid_L (voxelwise P<0.005; clusters >30; FDR correction). Furthermore, the most significant enhancement in ReHo values was observed for Postcentral_L, while the most prominent reduction was identified for ParaHippocampal_L (voxelwise P<0.005; clusters >30; FDR correction). Notably, correlation analysis with clinical scales revealed a robust positive correlation between the Cuneus_R score and the rate of change in the VAS score (r=0.9333, P<0.0001). CONCLUSIONS Long-term chronic lower back pain in patients with LDH manifests significant activation of the "AUN-DMN-S1-SAN" neural circuitry. The visual network, represented by the Cuneus_R, is highly likely to be a key brain network in which the analgesic efficacy of SMT becomes effective in treating LDH patients.

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.

Objective To evaluate the feasibility and safety of a domestically developed,single-arm single-port robotic system for performing complex gynecological surgeries under extreme conditions,such as ultra-remote locations and high-altitude environments.Methods In November and December 2024,a surgeon on the campus of West China Second Hospital,Sichuan University in Chengdu remotely manipulated a domestically developed single-arm,single-port robotic surgical system via a high-speed,low-latency communication network to perform two telesurgical procedures.The first procedure was a transumbilical single-port robot-assisted laparoscopic total hysterectomy,bilateral salpingectomy,and left ovarian cystectomy on a patient with multiple uterine fibroids at the Maternity and Child Health Hospital of Xizang Autonomous Region(distance between Chengdu and Lhasa>2 000 km and altitude difference>3 000 m).The second procedure was a transumbilical single-port robot-assisted laparoscopic total hysterectomy,bilateral salpingo-oophorectomy,and sentinel lymph node biopsy on a patient with FIGO stage IA endometrial cancer at Zhujiang Hospital,Southern Medical University in Guangzhou(the distance between Chengdu and Guangzhou>1 500 km).Perioperative data were collected and analyzed.Results Both procedures were successfully completed without conversion to laparotomy or the use of additional auxiliary ports.The operative times for the Chengdu-Lhasa and Chengdu-Guangzhou surgeries were 90 minutes and 135 minutes,respectively,with estimated blood loss≤50 mL in both cases.The intraoperative bidirectional network latency remained around 40 ms,and the total end-to-end latency was less than 60 ms.The surgeon reported no perceptible delay in instrumental response.Both patients recovered well postoperatively,and no surgery-related complications or disease recurrence were observed during follow-up until July 2025.Conclusion This study provides preliminary evidence supporting the feasibility and safety of a domestically developed single-arm,single-port robotic system for performing complex gynecological surgeries in ultra-remote and high-altitude settings.This technical approach offers a promising solution to address geographic disparities in access to high-quality medical resources and demonstrates significant potential for improving the availability of advanced minimally invasive surgery in remote areas and regions of special settings.

Compound 1 possesses a rare 6/7 bicyclic skeleton.

Adolescent idiopathic scoliosis (AIS) is a common spinal deformity in adolescents, with potential causes etiologies associated with mesenchymal stem cells, genetic factors, histological features, and biomechanical aspects. Biomechanically, the pelvis, serving as the central and majort load-bearing structure, exhibits morphological and alignment abnormalities highly correlated with the development of AIS. Recent studies have extensively explored three-dimensional pelvic parameters and kinematics, demonstrating that abnormal pelvic characteristics may contribute to AIS onset and progression and are increasingly incorporated into clinical interventions. This review summarizes sagittal and coronal features of the spine-pelvis, as well as the influence of three-dimensional kinematic features on the pathogenesis of AIS, providing insights for advancing the study of spine-pelvis features related to AIS.
