OBJECTIVES:
To investigate the protective effects of graphene heating film far-infrared (FIR) hyperthermia therapy against frostbite in mice and its impacts on microcirculation and coagulation function.
METHODS:
Seventy-six C57BL/6J mice were randomized into control, model, graphene-FIR, and carbon fiber-FIR groups. After 7-day FIR intervention (4 h/day), the mice were subjected to acute (4 ℃, 4 h) and intermittent (4 ℃, 4 h/day for 3 days) cold exposure and the changes in rectal temperature were monitored. In liquid nitrogen frostbite experiment, 24 ICR mice were divided into model, graphene-FIR, and carbon fiber-FIR groups, and after a 7-day FIR pretreatment (4 h/day), the liquid nitrogen frostbite models were established and apparent scores of the wounds were assessed on days 3 and 6 after modeling. In carrageenan-induced thrombosis experiment, 40 ICR mice were allocated to control, model, graphene-FIR, carbon fiber-FIR, and prazosin groups to test the effect of a 7-day FIR intervention on thrombosis induced by intraperitoneal carrageenan injection (2.5 mg/kg) by measuring thrombus length, blood perfusion, and serum biomarkers (6-keto-PGF1α, TXB2, t-PA, IL-6, IL-1β, TNF‑α) 24 h after the injection.
RESULTS:
The mice in graphene-FIR group showed significantly elevated rectal temperature in cold exposure tests. In mice with liquid nitrogen-induced frostbite, graphene-FIR treatment significantly reduced the wound scores and reduced frostbite area, producing better effects than carbon fiber. In mice with carrageenan-induced thrombosis, graphene-FIR treatment significantly decreased tail thrombosis length and thrombosis area, increased blood perfusion, lowered serum levels of TXB2, TNF-α and IL-6, and increased the levels of 6-keto-PGF1α and t-PA.
CONCLUSIONS
Graphene heating film FIR therapy can alleviate frostbite injury in mice by improving microcirculation, suppressing thrombosis and inflammatory responses, and reducing coagulation dysfunction.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.

Radiation-induced thrombocytopenia (RIT) faces a perplexing challenge in the clinical treatment of cancer patients, and current therapeutic approaches are inadequate in the clinical settings. In this research, oxymatrine, a new molecule capable of healing RIT was screened out, and the underlying regulatory mechanism associated with magakaryocyte (MK) differentiation and thrombopoiesis was demonstrated. The capacity of oxymatrine to induce MK differentiation was verified in K-562 and Meg-01 cells in vitro. The ability to induce thrombopoiesis was subsequently demonstrated in Tg (cd41:enhanced green fluorescent protein (eGFP)) zebrafish and RIT model mice. In addition, we carried out network pharmacological prediction, drug affinity responsive target stability assay (DARTS) and cellular thermal shift assay (CETSA) analyses to explore the potential targets of oxymatrine. Moreover, the pathway underlying the effects of oxymatrine was determined by Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, Western blot (WB), and immunofluorescence. Oxymatrine markedly promoted MK differentiation and maturation in vitro. Moreover, oxymatrine induced thrombopoiesis in Tg (cd41:eGFP) zebrafish and accelerated thrombopoiesis and platelet function recovery in RIT model mice. Mechanistically, oxymatrine directly binds to toll-like receptor 2 (TLR2) and further regulates the downstream pathway stimulator of interferon genes (STING)/nuclear factor-kappaB (NF-κB), which can be blocked by C29 and C-176, which are specific inhibitors of TLR2 and STING, respectively. Taken together, we demonstrated that oxymatrine, a novel TLR2 agonist, plays a critical role in accelerating MK differentiation and thrombopoiesis via the STING/NF-κB axis, suggesting that oxymatrine is a promising candidate for RIT therapy.

ObjectiveTo investigate the mechanism by which Huanglian Jiedutang (HLJDT) inhibits pyroptosis and neuroinflammation in Alzheimer's disease (AD) mice via the NOD-like receptor protein 3 (NLRP3)/cysteinyl aspartate-specific protease-1 (Caspase)-1/gasdermin D (GSDMD) pathway. MethodsThirty APP/PS1 double transgenic mice were randomly and evenly divided into the model group (model group), the positive control group (Donepezil group, 0.65 mg·kg-1), and the HLJDT treatment group (HLJDT group, 5.2 g·kg-1). Ten C57BL/6 mice were assigned to the blank control group (control group). The Morris water maze and novel object recognition tests were used to evaluate learning and memory abilities. Nissl staining was employed to observe the morphology, quantity, and distribution of neurons in the hippocampal region. Golgi staining was used to examine the morphology and density of neuronal dendritic spines in the hippocampus. Real-time quantitative polymerase chain reaction (Real-time PCR) was performed to detect the mRNA expression of neuroinflammation-related factors and genes in the NLRP3/Caspase-1/GSDMD pyroptosis pathway in the hippocampus. Western blot was used to detect the expression of postsynaptic density protein 95 (PSD95), amyloid precursor protein (APP), inflammatory factors including nuclear factor-κB (NF-κB), phosphorylated NF-κB (p-NF-κB), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), as well as pyroptosis pathway-related proteins including NLRP3, Caspase-1, GSDMD, and GSDMD-N. ResultsCompared with the control group, the model group exhibited significantly decreased learning and memory abilities (P<0.01), reduced numbers of neurons in the hippocampal CA3 region and dendritic spines in the hippocampal CA1 region (P<0.01), and significantly increased hippocampal mRNA expression levels of NLRP3, Caspase-1, GSDMD, NF-κB, TNF-α, IL-1β, and IL-18 (P<0.01). Protein levels of PSD95 were markedly decreased, while the expression levels of NLRP3, Caspase-1, GSDMD, p-NF-κB/NF-κB, TNF-α, IL-1β, and APP were significantly elevated (P<0.01). Compared with the model group, both the Donepezil and HLJDT groups showed significantly improved learning and memory abilities (P<0.05, P<0.01), increased numbers of hippocampal neurons in the hippocampal CA3 region and dendritic spines in the hippocampal CA1 region (P<0.01), and significantly decreased hippocampal mRNA expression levels of NLRP3, Caspase-1, GSDMD, NF-κB, TNF-α, IL-1β, and IL-18 (P<0.05, P<0.01). Protein levels of NLRP3, Caspase-1, GSDMD, p-NF-κB/NF-κB, TNF-α, IL-1β, and APP were significantly downregulated, while PSD95 expression was significantly upregulated (P<0.05, P<0.01). There was no statistically significant difference in GSDMD-N levels in the Donepezil group, while GSDMD-N expression was significantly decreased in the HLJDT group (P<0.05). ConclusionThis study confirms that HLJDT can improve learning and memory abilities in APP/PS1 double transgenic mice, and attenuate neuronal loss and synaptic damage, possibly through inhibition of pyroptosis via the NLRP3/Caspase-1/GSDMD pathway.

The S100 calcium-binding protein family member A16(S100A16)exhibits differential expression in various malignant tumors and plays a critical role in tumor progression,including effects on tumor cell proliferation,apoptosis,adhesion,epithelial-mesenchymal transition,migration,and invasion.Its aberrant expression is associated with adverse clinical outcomes,making it a potential prognostic biomarker.Fur-thermore,S100A16 is closely linked to the infiltration of immune cells within the tumor microenvironment,contributing to the establish-ment of an immunosuppressive state.The expression level of S100A16 in tumor-associated endothelial cells may also correlate with the formation of an inhibitory immune microenvironment.Additionally,S100A16 has been implicated in tumor chemotherapy resistance.This review summarizes recent advances in our understanding of the mechanisms by which S100A16 contributes to different types of tumors,its regulatory effects on the tumor immune microenvironment,and its role in drug treatment resistance.The aim of this review is to elucidate the underlying mechanisms of tumor prevention and treatment and provide a theoretical foundation for overcoming drug resistance in can-cer therapy.

Objective:To evaluate the efficacy and feasibility of a domestically developed robotic surgical system based on fiber-optic dedicated line communication in cross-regional urological telesurgery.Methods:This was multicenter,single-arm,retrospective case series study. The data of patients who underwent urological telesurgeries using the telesurgical system between January 2023 and December 2024 were analyzed. The cohort included 59 patients from seven hospitals across China. Among the patients,47 were male(79.7%)and 12 were female(20.3%),with a median age of 63.0(56.0,68.0)years and a body mass index of(24.7 ± 3.0)kg/m 2. Surgical procedures included 32 radical prostatectomies,24 partial nephrectomies,one radical nephrectomy,one adrenalectomy,and one ureteral reconstruction. The perioperative indicators,pathological results and postoperative complications were analyzed. The network monitoring data were collected,and the perioperative data of patients,remote system monitoring data and costs were compared between the two communication modes of optical transport network(OTN)and cloud-connect network(CCN). Results:All 59 remote surgeries were successfully completed,with a mean operative time of(138.0 ± 54.0)minutes,median intraoperative blood loss of 50.0(30.0,100.0)ml and a postoperative hospital stay of 5.0(4.0,6.0)days. No cases required reoperation,Clavien-Dindo grade ≥3 complications,or readmission. The geographical distance between the primary and remote surgical sites ranged from 450 to 2 800 km. Network monitoring revealed increased bidirectional latency with distance increasing:the shortest latency time(Hefei-Hangzhou,450 km)was(16.59 ± 0.80)ms,while the longest(Harbin-Hangzhou,2 200 km)latency time was(53.31 ± 0.31)ms. Average frame loss per procedure was 0?1.27 frames. The results of subgroup analysis comparing OTN and CCN communication modes showed no significant differences in operative time[(130.7 ± 70.5)minutes vs.(142.1 ± 42.9)minutes, P = 0.442],postoperative hospitalization[6.0(4.0,8.0)d vs. 5.0(4.0,6.0)d, P = 0.581],or readmission rates(0 vs. 0). However,CCN demonstrated significant cost advantages with 500 RMB per operation vs. 3 000 RMB per operation for OTN. Conclusions:Urological telesurgery using fiber-optic communication is feasible. The CCN mode,with its cost-effectiveness,excellent usability,and multi-point interconnection flexibility,is currently the preferred communication model for telesurgical applications.
