Peripheral artery disease(PAD),commonly encountered in vascular surgery,predominantly affects the lower limbs and presents with ischemic symptoms resulting from atherosclerosis.It carries risks of adverse limb events and cardiovascular events.Antithrombotic therapy remains a cornerstone in the management of PAD.This article reviews the evidence and research progress regarding dual-pathway antithrombotic therapy for PAD.Multiple clinical trials have demonstrated that,compared to single antiplatelet therapy,dual-pathway antithrombotic therapy significantly reduces the risks of major adverse limb events and major adverse cardiovascular events without a significant increase in bleeding risk.For high-risk patients,such as those with advanced age,multivessel disease,comorbid coronary artery disease,or those undergoing endovascular revascularization,the benefits of dual-pathway antithrombotic therapy are particularly pronounced.Current clinical guidelines have incorporated dual-pathway antithrombotic therapy into their recommendations,standardized criteria for identifying the most appropriate patient populations remain lacking.Despite its advantages in reducing adverse events,its long-term safety profile and optimal target populations warrant further investigation.

Objective Ticks serve as vectors for transmitting Babesia microti.However,the specific mechanism remains unclear.This study aimed to investigate the effect of tick autophagy molecules on the proliferation of Babesia microti.Methods An experimental model of infected and uninfected mice was used to collect tick materials for proteomic analysis to identify differentially expressed autophagy-related molecules in Haemaphysalis longicornis.The cloning of the HlATG8 gene,protein expression,and production of polyclonal antibodies were completed.The HlATG8 gene was then knocked down using RNAi interference technology.Results The tick autophagy molecule,HlATG8,was identified and found to be significantly upregulated in ticks infected with Babesia microti.The load of Babesia microti in ticks increased significantly following the knockdown of the HlATG8 gene.Conclusions The tick autophagy molecule in Hae.longicornis,HlATG8,inhibits the proliferation of Babesia.

Periodontal bone defects, primarily caused by periodontitis, are highly prevalent in clinical settings and manifest as bone fenestration, dehiscence, or attachment loss, presenting a significant challenge to oral health. In regenerative medicine, harnessing developmental principles for tissue repair offers promising therapeutic potential. Of particular interest is the condensation of progenitor cells, an essential event in organogenesis that has inspired clinically effective cell aggregation approaches in dental regeneration. However, the precise cellular coordination mechanisms during condensation and regeneration remain elusive. Here, taking the tooth as a model organ, we employed single-cell RNA sequencing to dissect the cellular composition and heterogeneity of human dental follicle and dental papilla, revealing a distinct Platelet-derived growth factor receptor alpha (PDGFRA) mesenchymal stem/stromal cell (MSC) population with remarkable odontogenic potential. Interestingly, a reciprocal paracrine interaction between PDGFRA⁺ dental follicle stem cells (DFSCs) and CD31⁺ Endomucin⁺ endothelial cells (ECs) was mediated by Vascular endothelial growth factor A (VEGFA) and Platelet-derived growth factor subunit BB (PDGFBB). This crosstalk not only maintains the functionality of PDGFRA⁺ DFSCs but also drives specialized angiogenesis. In vivo periodontal bone regeneration experiments further reveal that communication between PDGFRA⁺ DFSC aggregates and recipient ECs is essential for effective angiogenic-osteogenic coupling and rapid tissue repair. Collectively, our results unravel the importance of MSC-EC crosstalk mediated by the VEGFA and PDGFBB-PDGFRA reciprocal signaling in orchestrating angiogenesis and osteogenesis. These findings not only establish a framework for deciphering and promoting periodontal bone regeneration in potential clinical applications but also offer insights for future therapeutic strategies in dental or broader regenerative medicine.

Objective:To analyze the efficacy and safety of standard chemotherapy and immune checkpoint inhibitors (CI) combined with radiotherapy (RT) in driver-gene negative (wild-type) oligometastatic non-small cell lung cancer (NSCLC) patients with central nervous system involvement.Methods:In this multicenter retrospective cohort study, oligometastatic NSCLC patients receiving first-line chemo-immunotherapy-based therapy were analyzed. Between January 2017 and January 2023, a total of 98 eligible patients were enrolled from the National Cancer Center/Cancer Hospital (Beijing/Shenzhen) and Shanxi Province Cancer Hospital. All participants were divided into chemo-immunotherapy (CI) group (28.6%, n=28) and chemo-immuno-radiotherapy (CIR) group (71.4%, n=70) according to whether receiving radiotherapy. Baseline characteristics were well-balanced between two groups, with no statistically significant differences (all P>0.05). The primary endpoint of the study was overall survival (OS), while progression-free survival (PFS) was designated as a key secondary endpoint. Qualitative data were compared by Chi-square test. Survival analysis was conducted using Kaplan-Meier method, and prognostic analysis was performed by multivariate Cox regression models. Results:The median PFS in the CIR and CI groups was 21.8 and 11.5 months, respectively, and the difference was not statistically significant ( P=0.211). The median OS in the CIR group was significantly better ( P=0.036) than 25.3 months in the CI group. The median OS in the CIR group was not reached. The 2-year local regional control rates for the whole brain radiotherapy patients, stereotactic radiotherapy / stereotactic radiosurgery patients and CI groups were 33.3% ,100% and 83.4%, respectively. Multivariate analysis showed that brain radiotherapy was an independent protective factor for OS in patients with oligometastatic brain metastases at baseline ( HR=0.47, 95% CI=0.22-0.99, P=0.047). Subgroup analysis revealed that patients with 1-3 metastatic lesions benefited from radiotherapy (PFS: HR=0.47, 95% CI=0.22-1.03, P=0.060; OS: HR=0.34, 95% CI=0.12-0.98, P=0.046). Conclusions:For central nervous system involved oligometastatic NSCLC patients, the integration of chemo-immunotherapy with radiotherapy is well tolerated and can improve the efficacy, particularly among those with a limited number of metastatic lesions.

To elucidate the mechanism by which steaming affects the quality of Curcuma kwangsiensis root tubers, methods such as LSCM, RVA, dual-wavelength spectrophotometry, LF-NMR, and LC-MS were employed to qualitatively and quantitatively detect changes in starch gelatinization characteristics, water distribution, and material composition of C. kwangsiensis root tubers under different steaming durations. Based on multivariate statistical analysis, the correlation between differences in gelatinization parameters, water distribution, and terpenoid material composition was investigated. The results indicate that steaming affects both starch gelatinization and water distribution in C. kwangsiensis. During the steaming process, transformations occur between amylose and amylopectin, as well as between semi-bound water and free water. After 60 min of steaming, starch gelatinization and water distribution reached an equilibrium state. The content of amylopectin, the amylose-to-amylopectin ratio, and parameters such as gelatinization temperature, viscosity, breakdown value, and setback value were significantly correlated(P≤0.05). Additionally, the amylose-to-amylopectin ratio was significantly correlated with total free water and total water content(P≤0.05). Steaming induced differences in the material composition of C. kwangsiensis root tubers. Clustering of primary metabolites in the OPLS-DA model was distinct, while secondary metabolites were classified into 9 clusters using the K-means clustering algorithm. Differential terpenoid metabolites such as(-)-α-curcumene were significantly correlated with zerumbone, retinal, and all-trans-retinoic acid(P<0.05). Curcumenol was significantly correlated with isoalantolactone and ursolic acid(P<0.05), while all-trans-retinoic acid was significantly correlated with both zerumbone and retinal(P<0.05). Alpha-tocotrienol exhibited a significant correlation with retinal and all-trans-retinoic acid(P<0.05). Amylose was extremely significantly correlated with(-)-α-curcumene, curcumenol, zerumbone, retinal, all-trans-retinoic acid, and α-tocotrienol(P<0.05). Amylopectin was significantly correlated with zerumbone(P<0.05) and extremely significantly correlated with(-)-α-curcumene, curcumenol, zerumbone, retinal, all-trans-retinoic acid, and 9-cis-retinoic acid(P<0.01). The results provide scientific evidence for elucidating the mechanism of quality formation of steamed C. kwangsiensis root tubers as a medicinal material.

Objective:To explore the clinical effect of treating complex talar neck fractures with double-column fixation using plates and cannulated screws.Methods:A retrospective analysis was performed on the data of 13 patients with complex talar neck fractures treated with double-column fixation using plates and cannulated screws at Tianjin Hospital, Tianjin University from June 2019 to November 2023. There were 9 males and 4 females, with an age of 42.1±17.7 years (range, 15-66 years). There were 5 cases on the left and 8 cases on the right. Four cases were caused by traffic accidents, 8 by falling from a height, and 1 by a heavy object injury. According to the Hawkins classification, there were 12 cases of type II and 1 case of type III talar neck fractures. All the fractures were comminuted, including 12 cases of talar neck combined with talar body, and 3 cases combined with subluxation of subtalar joint. The time from injury to surgery was 3.3±1.6 d (range, 1-6 d). All patients were treated with anteromedial combined anterolateral approach, plate and cannulated screw double-column fixation pattern. The healing time of fractures and the occurrence of complications were recorded. Postoperative anteroposterior and lateral X-ray images were taken to assess the quality of fracture reduction based on the presence or absence of step-offs and angulation after reduction of fractures at the neck or body of the talus. The functional outcome was evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale.Results:All 13 patients were followed up for 33.8±15.2 months (range, 12-53 months). All fractures healed, and the healing time was 17.2±2.8 weeks (range, 13-23 weeks). Postoperative X-ray evaluation showed that 10 cases had anatomical reduction and 3 cases had near-anatomical reduction. After operation, there was no loosening or breakage of implant, loss of fracture reduction, irritation of skin and soft tissue by internal fixation. The AOFAS score was 88.1±13.0 points (range, 48-100 points), with 9 excellent cases, 3 good cases, and 1 poor case. Superficial skin necrosis in one surgical incision healed after dressing exchange. At the 1-year follow-up after surgery, 1 case developed avascular necrosis of the talus without collapse. And at the last follow-up (postoperative 13 to 53 months), 5 cases developed post-traumatic arthritis.Conclusion:Plate and cannulated screw double-column fixation in the treatment of complex talar neck fractures can achieve satisfactory reduction and strong fixation effects, which is beneficial in reducing complications related to poor reduction.

OBJECTIVE: To explore the potential effects and mechanisms of Liang-Ge-San (LGS) for the treatment of acute respiratory distress syndrome (ARDS) through network pharmacology analysis and to verify LGS activity through biological experiments. METHODS: The key ingredients of LGS and related targets were obtained from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform. ARDS-related targets were selected from GeneCards and DisGeNET databases. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed using the Metascape Database. Molecular docking analysis was used to confirm the binding affinity of the core compounds with key therapeutic targets. Finally, the effects of LGS on key signaling pathways and biological processes were determined by in vitro and in vivo experiments. RESULTS: A total of LGS-related targets and 496 ARDS-related targets were obtained from the databases. Network pharmacological analysis suggested that LGS could treat ARDS based on the following information: LGS ingredients luteolin, wogonin, and baicalein may be potential candidate agents. Mitogen-activated protein kinase 14 (MAPK14), recombinant V-Rel reticuloendotheliosis viral oncogene homolog A (RELA), and tumor necrosis factor alpha (TNF-α) may be potential therapeutic targets. Reactive oxygen species metabolic process and the apoptotic signaling pathway were the main biological processes. The p38MAPK/NF-κ B signaling pathway might be the key signaling pathway activated by LGS against ARDS. Moreover, molecular docking demonstrated that luteolin, wogonin, and baicalein had a good binding affinity with MAPK14, RELA, and TNF α. In vitro experiments, LGS inhibited the expression and entry of p38 and p65 into the nucleation in human bronchial epithelial cells (HBE) cells induced by LPS, inhibited the inflammatory response and oxidative stress response, and inhibited HBE cell apoptosis (P<0.05 or P<0.01). In vivo experiments, LGS improved lung injury caused by ligation and puncture, reduced inflammatory responses, and inhibited the activation of p38MAPK and p65 (P<0.05 or P<0.01). CONCLUSION LGS could reduce reactive oxygen species and inflammatory cytokine production by inhibiting p38MAPK/NF-κ B signaling pathway, thus reducing apoptosis and attenuating ARDS.
