Flap transplantation is a critical surgical strategy for the reconstruction of tissue defects caused by trauma, tumor resection, and congenital malformations, and its survival rate directly determines surgical efficacy and patient prognosis. Following transplantation, flaps inevitably undergo ischemia-reperfusion (I/R) injury, during which oxidative stress, inflammatory responses, and metabolic disturbances are intricately intertwined, ultimately leading to cellular injury and tissue necrosis. Recent studies have demonstrated that multiple forms of programmed cell death—including apoptosis, pyroptosis, ferroptosis, necroptosis, and PANoptosis—play central roles in flap I/R injury. The extensive crosstalk and molecular interactions among these pathways form a highly complex cell death network. Specifically, apoptosis is mediated by the imbalance of Bcl-2 family proteins and the activation of cysteine-dependent aspartate-specific protease (caspase) cascades; pyroptosis is driven by the NLRP3-caspase-1-GSDMD axis, resulting in membrane pore formation and the release of pro-inflammatory cytokines; ferroptosis is characterized by iron-dependent lipid peroxidation and dysfunction of glutathione peroxidase 4 (GPX4); necroptosis is triggered by the receptor-interacting serine/threonine-protein kinase 1 (RIPK1)-RIPK3-MLKL signaling complex, leading to membrane rupture; and PANoptosis represents an integrated form of inflammatory cell death that coordinates multiple death pathways. Importantly, these forms of programmed cell death are not independent but are interconnected through extensive signaling crosstalk. Key regulatory molecules, including caspase-8, reactive oxygen species (ROS), nuclear factor-κB (NF-κB), and nuclear factor erythroid 2-related factor 2 (Nrf2), collectively modulate the dynamic balance among these pathways. Therefore, the multidimensional interplay and spatiotemporal dynamics of programmed cell death constitute a fundamental pathological basis of flap I/R injury. This review systematically summarizes the latest advances in the mechanisms and interactions of various programmed cell death pathways in flap I/R injury, aiming to elucidate the underlying regulatory network. These insights may provide novel theoretical foundations for optimizing flap protection strategies, improving flap survival, and promoting tissue repair.

Primary liver cancer is a common malignant tumor in China. The current main treatment methods include surgical resection, liver transplantation, interventional therapy, radiofrequency ablation, chemotherapy, targeted therapy, and immunotherapy. Yttrium-90 microsphere selective internal radiation therapy (⁹⁰Y-SIRT) represents a critical treatment option for converting unresectable intermediate to advanced hepatocellular carcinoma. This report details a case of a patient with a giant hepatocellular carcinoma in the right lobe treated with ⁹⁰Y resin microsphere at the Third Affiliated Hospital of Sun Yat-sen University. Post-treatment, the tumor showed significant necrosis and reduction in size, with a marked decrease in alpha fetoprotein (AFP) levels and notable improvement in clinical symptoms. The case highlights the substantial efficacy of ⁹⁰Y-SIRT in controlling tumor progression and enhancing patient quality of life.

Objective To investigate the relationship between kinase insert domain receptor(KDR)rs2305948 polymorphism and clopidogrel resistance(CR)in patients with acute coronary syndrome after receiving percutaneous coronary intervention(PCI).Methods A total of 468 patients with acute coronary syndrome,who were admitted to the Zhangjiakou Municipal First Hospital of China from September 2022 to September 2023,were selected as the subjects of study.All patients received PCI treatment and took medication of clopidogrel after the treatment.The occurrence of CR was recorded.The factors influencing the occurrence of CR were analyzed.The clinical significance of KDR rs2305948 polymorphism in predicting CR in patients with acute coronary syndrome after receiving PCI was evaluated.Results Of 468 patients with acute coronary syndrome,116(24.79％)developed CR.Logistic multivariate regression analysis indicated that low-density lipoprotein cholesterol(LDL-C,95％CI=1.420-8.390,OR=3.452),type 2 vascular endothelial growth factor receptor(VEGFR-2,95％CI=1.374-8.118,OR=3.340),KDR rs2305948 T/T genotype(95％CI=1.677-9.905,OR=4.076),and T allele(95％CI=1.390-8.207,OR=3.377)were the independent factors influencing the occurrence of CR inpatients with acute coronary syndrome after receiving PCI(all P＜0.05).Receiver operating characteristic(ROC)curve analysis showed that the sensitivity,specificity,and area under ROC curve(AUC)of the T/T genotype of KDR rs2305948 in predicting CR in patients with acute coronary syndrome after receiving PCI were 75.86％,70.45％,and 0.773(95％CI=0.666-0.880)respectively.Conclusion In patients with acute coronary syndrome after receiving PCI,the risk of developing CR is higher.The KDR rs2305948 polymorphism is correlated with CR in patients with acute coronary syndrome after receiving PCI,and it has a certain predictive value for CR.

Objective:To investigate the impact of early invasive arterial blood pressure (IBP) monitoring on survival and neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR).Methods:This retrospective cohort study analyzed 44 OHCA patients receiving ECPR between January 2021 and January 2023. Patients were divided into: Early intervention group : IBP established within 3 min of ECMO initiation; Late intervention group : IBP established after ICU admission. Baseline characteristics, ECMO parameters, and clinical outcomes were compared. Multivariable logistic regression (adjusted for age, initial rhythm, etc.) and Spearman's correlation were used.Results:This study included a total of 44 patients treated with OHCA and ECPR, divided into an early intervention group of 23 cases and a late intervention group of 21 cases. The early intervention group showed significantly higher: Survival to discharge (43.5% vs. 9.5%, P<0.05), Good neurological recovery (CPC 1-2: 34.8% vs. 9.5%, P<0.05).Early intervention independently predicted survival (adjusted OR=18.84, 95% CI:1.97-179.98, P=0.01). Stratified analysis by pH (cutoff 7.0) demonstrated consistent benefits in both pH>7.0 ( aOR=0.392, 95% CI:0.106-0.678) and pH≤7.0 subgroups ( aOR=0.385, 95% CI: 0.075-0.695; interaction P=0.183). Early IBP positively correlated with CPC scores ( ρ=0.40, P=0.007). Conclusions:Early IBP monitoring significantly improves survival and neurological outcomes in OHCA-ECPR patients, supporting its integration into standardized protocols.

Kidney deficiency syndrome is a common clinical syndrome in traditional Chinese medicine （TCM）. With the progress of science and technology， clinical and animal experiments on kidney deficiency syndrome have made remarkable progress. Research on kidney deficiency and the nature of "kidney" involves a large number of physiological and pathological bases， which are closely related to physiological and pathological links in the human body， among which the neuroendocrine-immune network shares the closest relationship. However， there are still many challenges in modern research on kidney deficiency syndrome， such as expert consensus on clinical diagnostic criteria and evaluation indexes and optimization of animal experimental models. In the past decade， a large number of clinical and animal experiments have been reported in the literature on kidney deficiency syndrome， among which the literature focusing on the combination of disease and syndrome is predominant， and most of them focus on kidney Yang deficiency and kidney Yin deficiency， involving the exploration of many pathological mechanisms. Research on the mechanisms related to kidney deficiency syndrome encompasses multiple signaling pathways and various biochemical indicators， including the phosphatidylinositol 3-kinase/protein kinase B/nuclear factor-erythroid 2-relatedfactor-2（PI3K/Akt/Nrf2） signaling pathway， the Toll-like receptor 4/myeloid differentiation factor88/nuclear factor-κB（TLR4/MyD88/NF-κB） signaling pathway， the Janus kinase 2/signal transducer and activator of transcription 3（JAK2/STAT3） signaling pathway， Osteoprotectin/nuclear factor-κB receptor activator ligand/receptor activator of nuclear factor-κB （OPG/RANKL/RANK） signaling pathway. The biochemical indicators cover the cyclic adenosine monophosphate/cyclic guanosine monophosphate （cAMP/cGMP） ratio， Na⁺-K⁺-ATPase activity， Ca²⁺-Mg²⁺-ATPase activity， adrenocorticotropic hormone （ACTH）， polycorticosterone （CORT）， 17-OHCS， and other sex hormone indicators， providing crucial reference values for diagnosing kidney Yang deficiency or kidney Yin deficiency. The literature related to kidney deficiency syndrome over the past decade was collated and excavated， with a view to providing a reference for research on kidney deficiency syndrome.
