ObjectiveTo observe the activation patterns and functional connectivity in the prefrontal cortex of patients with post-stroke anxiety (PSA) using functional near-infrared spectroscopy, in order to explore the underlying neural mechanism. MethodsFrom December, 2024 to September, 2025, 120 stroke patients were selected in Changzhou De'an Hospital. They were divided into PSA group (n = 60) and non-PSA group (n = 60) according to the score of Hamilton Anxiety Scale (HAMA). All patients wore an 18-channel fNIRS acquisition cap for detection. The differences in resting-state functional connectivity between the frontopolar cortex (FPC) and dorsolateral prefrontal cortex (DLPFC) were examined in both groups, as well as task-related activation in these brain regions. ResultsResting-state functional connectivity analysis revealed no statistically significant difference in network connectivity between two groups in the FPC and DLPFC regions (|t| < 1.301, P > 0.05). Task-related activation results revealed significantly reduced activation in the contralateral FPC of PSA group compared to the non-PSA group (Z = -2.063, P < 0.05). Activation levels in this region showed a negative correlation with the scores of HAMA (ρ = -0.201, P = 0.028). ConclusionActivation decreased in the contralateral frontal pole during the task state for patients with PSA, and the activation levels negatively correlates with anxiety severities.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

Objective To observe the effect of RAW264.7 cells on calcium sparks in a insulin resistance model of C2C12 cells induced by sodium palmitate.Methods C2C12 cells and RAW264.7 cells were co-cultured to simulate the in vivo state of skeletal muscle.C2C12 cells were cultured in high-glucose medium containing 2%horse serum to induce differentiation into mature myotubes,and then divided into 5 groups:control(RAW264.7 cells),co-culture of C2C12 with RAW264.7,C2C12 alone,co-culture of C2C12 with RAW264.7 plus sodium palmitate(PA),and C2C12 alone with PA.PA of 5 mmol/L was used to induce insulin resistance in C2C12 cells for 24 hours.Revived and expanded RAW264.7 cells were evenly added to C2C12 cells and co-cultured for two days.Subsequently,cells were maintained in modified suspension culture,and both cell types were loaded with the calcium ion fluorescent probe Fluo-4 AM.Finally,Paraxanthine was used to induce intracellular calcium sparks,which was captured and recorded under a laser confocal microscope.Results No significant calcium signal change was observed in the control group.Co-cultured C2C12 cells exhibited rapid and pronounced calcium signal changes,whereas calcium signals in C2C12 cells cultured alone increased slowly throughout the observation period without a sharp decline.The peak calcium signal was reached significantly faster in co-cultured C2C12 cells than that in C2C12 cells cultured alone(P<0.001).With PA induction,calcium signal changes in C2C12 cells were not markedly altered,while distinct calcium fluctuations were still observed in co-cultured C2C12 cells,and the peak calcium signal was reached significantly faster in co-cultured C2C12 cells than that in C2C12 cells cultured alone(P<0.001).Conclusion RAW264.7 cells enhance the dynamic responsiveness of calcium signaling in both normal and PA-stimulated C2C12 cells.

Objective To explore the potential central mechanisms of functional electrical stimulation(FES)hand cycling in promot-ing upper limb motor recovery after stroke.Methods A total of 35 stroke patients hospitalized in the Rehabilitation Center of Changzhou De'an Hospital from May,2023 to December,2024 were enrolled.They sequentially completed 10-minute FES hand cycling and 10-minute sham stimulation(simple hand cycling)tasks.The task order was randomized via dice rolling.Functional near-in-frared spectroscopy(fNIRS)was used to monitor real-time cerebral hemodynamic changes during both tasks to calculate the overall functional connectivity(FC)strength and the FC strength within regions of interest.Results The overall FC strength was higher during the FES hand cycling task than during the sham task(t=2.591,P<0.05),as well as FC between the ipsilateral primary motor cortex(iM1)and ipsilateral somatosensory association cortex(iSAC),iM1 and contralateral somatosensory association cortex(cSAC),ipsilateral pre-motor and supple-mentary motor cortex(iPMC)and iSAC,iPMC and cSAC,iPMC and ipsilateral primary somatosensory cortex(iS1),iPMC and iM1,and contralateral pre-motor and supplementary motor cortex(cPMC)and iSAC(PFDR<0.05).Conclusion FES hand cycling can promote the cortical function remodeling between cerebral hemispheres and the af-fected hemisphere,to integrate sensory-motor function.
