    Abstract Objective: To systematically evaluate the efficacy and safety of radiofrequency ablation and liver resection in the therapeutic management of early-stage hepatocellular carcinoma.
    Method: We conducted a comprehensive search of domestic and foreign databases including PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang to retrieve literature on radiofrequency ablation and liver resection for the treatment of early hepatocellular carcinoma. The retrieved literature underwent thorough screening, and relevant data were extracted. Following the evaluation of the literature's quality, Meta-analysis was performed using RevMan 5.4 software.
    Results: In this study, a total of 11 documents were selected, comprising 1334 patients with hepatocellular carcinoma. Meta-analysis results indicated that there was no statistically significant difference in the 1-year overall survival rate [Relative risk (RR) = 1.01, 95% confidence intervals (CI) (0.98; 1.04)] and the 3-year overall survival rate [RR = 0.95, 95% CI (0.90; 1.01)] between the radiofrequency ablation and liver resection groups (p > 0.05). Similarly, there was no statistically significant difference in the 1-year disease-free survival rate [RR = 0.94, 95% CI (0.87; 1.01)] between the two groups. However, the 3-year disease-free survival rate [RR = 0.84, 95% CI (0.74; 0.96)] of patients in the radiofrequency ablation group was significantly lower than that in the hepatectomy group (p < 0.05). Notably, the incidence of complications [RR = 0.42, 95% CI (0.33; 0.55)] was significantly lower in the radiofrequency ablation group compared to the hepatectomy group. Conversely, the local recurrence rate [RR = 1.45, 95% CI (1.22; 1.73)] was significantly higher in the radiofrequency ablation group compared to the hepatectomy group (p < 0.05).
    Conclusion: During the treatment of hepatocellular carcinoma, hepatectomy demonstrates superior clinical efficacy compared to radiofrequency ablation, particularly in its ability to control tumor recurrence. However, radiofrequency ablation presents with fewer complications and a higher level of safety. These findings can serve as a valuable foundation for clinicians when selecting the most suitable treatment approaches for liver cancer.

    Abstract Background: Sepsis-associated AKI has been shown to be related to sepsis mortality. Macrophage activation and endothelial cell damage are involved in the progression of sepsis-associated AKI, but the specific mechanisms are still unclear.
    Methods: In vitro experiments, exosomes extracted from lipopolysaccharide (LPS) -stimulated macrophages were co-incubated with rat glomerular endothelial cells (RGECs) and then detected the injury markers of RGECs. Acid sphingomyelinase (ASM) inhibitor amitriptyline were used to investigate the role of ASM. In vivo experiment, exosomes produced by LPS-stimulated macrophages were injected into mice through tail vein to further explore the role of macrophage-derived exosomes. Moreover, ASM knockout mice were used to verify the mechanism.
    Result: In vitro, the secretion of macrophage exosomes increased upon the stimulation with LPS. Notably, macrophage-derived exosomes can cause glomerular endothelial cell dysfunction. In vivo, macrophage infiltration and exosome secretion in glomeruli of the LPS-induced AKI group increased. The exosomes produced by LPS-stimulated macrophages were injected into mice, which also led to the injury of renal endothelial cells. In addition, in the LPS-induced AKI mouse model, compared with wild-type mice, the secretion of exosomes in glomeruli of ASM gene knockout mice and the injury of endothelial cells were reduced.
    Conclusion: Our study shows that ASM regulates the secretion of macrophage exosomes, leading to endothelial cell injury, which may be a therapeutic target in sepsis-associated AKI.

    Abstract Background: Hepatocellular carcinoma is a major contributor to cancer-related deaths in China and ranks among the most prevalent malignant tumors. . The study aimed to assess the efficacy and adverse reactions of transcatheter arterial chemoembolization combined with apatinib in treating hepatocellular carcinoma with portal vein tumor thrombus.
    Methods: When treating hepatocellular carcinoma with a portal vein tumor thrombus, the computer retrieves eight databases to find controlled trials on the effects of transcatheter arterial chemoembolization combined with apatinib. The Cochrane Library, WanFang databases EMbase, PubMed, Web of Science, China Biomedical Literature Database (CBM), & CNKI are all retrieved by the computer. "Transcatheter arterial chemoembolization", "apatinib", & "hepatocellular carcinoma" are the search terms. As this a meta-analysis, Utilizing RevMan 5.3 software, data analysis was carried out following a thorough assessment of the quality of the literature.
    Results: This meta-analysis finally contained 7 papers. According to a meta-analysis, the disease control rate of the test category was considerably greater than that of the control category (odd Ratio OR: 1.65; 95% Cl: 1.17,2.33; P = .01). The experimental cohort's level of VEGF was substantially lower than that of the control group (standardized mean difference SMD:-25.38; 95% Cl: -28.69,-21.79; P < .01). According to a meta-analysis, caspase-8 levels in the group that underwent the experiment were substantially greater than those in the control category (SMD: 15.12; 95% Cl: 12.09, 18.15; P < .01). The test control experienced considerably less pain than the control sample (OR: 0.86; 95% Cl: 0.75,0.99; P = .033).
    Conclusion: The findings of this trial indicate that individuals with HCC & PVTT may benefit from TACE & apatinib together, as evidenced by disease control rate, VEGF, Caspase-8, pain, hypertension, nausea and vomiting, and more reputable studies are required to support the aforementioned conclusions.

    Abstract Molecularly imprinted polymers (MIPs) are synthetic polymers with predetermined selectivity for a given analyte. One major problem associated with MIPs is the inaccessibility of a large fraction of the recognition sites that remain buried within the polymeric matrix. To address this problem, the high selectivity imparted by the imprinting technique and the porosity of three-dimensional (3D) graphene oxide (GO)-based porous materials were utilized in this work to prepare a 3D GO-based Cu(II)-ion-imprinted material (hereafter denoted as IIM) via one-pot reactions of GO, chitosan (CS), and glutaraldehyde in the presence of Cu(II). Results of equilibrium binding experiments show that IIM has a high template-ion binding capacity (1.75 mmol g

Results of equilibrium binding experiments show that IIM has a high template-ion binding capacity (1.75 mmol g⁻¹) and good imprinting factor (2.19). Further, results of selectivity tests indicate that IIM has a high Cu(II)-recognition ability. IIM also has a fast binding rate and satisfactory reusability. In addition, the Langmuir isotherm model was well fitted with the experimental data, indicating the monolayer adsorption of Cu(II) ions. The present work provided a convenient approach to prepare 3D GO-based imprinted materials that are promising for enrichment or recycling of target compounds from wastewater.

    Abstract The present study aimed to investigate the value of intravoxel incoherent motion imaging (IVIM) and three-dimensional pulsed continuous arterial spin labeling (ASL) in assessing dynamic changes of the parotid gland in patients with nasopharyngeal carcinoma (NPC) following radiotherapy (RT). A total of 18 patients with NPC who underwent intensity-modulated RT were enrolled in the present study. All patients underwent conventional magnetic resonance imaging, plus IVIM and ASL imaging of the bilateral parotid glands within 2 weeks prior to RT, and 1 week (1W) and 3 months (3M) following RT. Pure diffusion coefficient (D), pseudo-diffusion coefficient (D*), perfusion fraction (F) and blood flow (BF) were analyzed. D and BF values were significantly increased from pre-RT to 1W post-RT [change rate: Median (IQR), ΔD

    Abstract The catalytic oxidation effect of MnSO₄ on As(III) by air in an alkaline solution was investigated. According to the X-ray diffraction (XRD), scanning electron microscope-energy dispersive spectrometer (SEM-EDS) and X-ray photoelectron spectroscopy (XPS) analysis results of the product, it was shown that the introduction of MnSO₄ in the form of solution would generate Na₀.₅₅Mn₂O₄·1.5H₂O with strong catalytic oxidation ability in the aerobic alkaline solution, whereas the catalytic effect of the other product MnOOH is not satisfactory. Under the optimal reaction conditions of temperature 90°C, As/Mn molar ratio 12.74:1, air flow rate 1.0 L/min, and stirring speed 300 r/min, As(III) can be completely oxidized after 2 hr reaction. The excellent catalytic oxidation ability of MnSO₄ on As(III) was mainly attributed to the indirect oxidation of As(III) by the product Na₀.₅₅Mn₂O₄·1.5H₂O. This study shows a convenient and efficient process for the oxidation of As(III) in alkali solutions, which has potential application value for the pre-oxidation of arsenic-containing solution or the detoxification of As(III).

    Abstract The traditional Grey Wolf Optimization algorithm (GWO) has received widespread attention due to features of strong convergence performance, few parameters, and easy implementation. However, in actual optimization projects, there are problems of slow convergence speed and easy to fall into local optimal solution. The paper proposed a Grey Wolf Optimization algorithm based on Cauchy-Gaussian mutation and improved search strategy (CG-GWO) in response to the above problems. The Cauchy-Gaussian mutation operator is introduced to increase the population diversity of the leader wolves and improve the global search ability of the algorithm. This work retains outstanding grey wolf individuals through the greedy selection mechanism to ensure the convergence speed of the algorithm. An improved search strategy was proposed to expand the optimization space of the algorithm and improve the convergence accuracy. Experiments are performed with 16 benchmark functions covering unimodal functions, multimodal functions, and fixed-dimension multimodal functions to verify the effectiveness of the algorithm. Experimental results show that compared with four classic optimization algorithms, particle swarm optimization algorithm (PSO), whale optimization algorithm (WOA), sparrow optimization algorithm (SSA), and farmland fertility algorithm (FFA), the CG-GWO algorithm shows better convergence accuracy, convergence speed, and global search ability. The proposed algorithm shows the same better performance compared with a series of improved algorithms such as the improved grey wolf algorithm (IGWO), modified Grey Wolf Optimization algorithm (mGWO), and the Grey Wolf Optimization algorithm inspired by enhanced leadership (GLF-GWO).

    Abstract Traditional risk assessments of chiral pesticides mainly depend on racemic form, which is often incomprehensive. This study conducted systemic investigations on the bioactivity, toxicity, and ecotoxicological effects of hexythiazox (HTZ) at the enantiomer level. The elution order and absolute configuration of HTZ enantiomers were determined. (4R, 5R)-(+)-HTZ exhibited 708 and 1719 times higher bioactivity against Tetranychus cinnabarinus and Tetranychus urticae eggs than (4S, 5S)-(-)-HTZ, respectively. Molecular docking indicated greater interactions between (4R, 5R)-(+)-HTZ and chitin synthase leading to higher bioactivity of (4R, 5R)-(+)-HTZ. However, (4S, 5S)-(-)-HTZ induced greater changes in protein and malondialdehyde content, and antioxidant and detoxification enzyme activities than (4R, 5R)-(+)-HTZ in earthworms. Furthermore, integrated biomarker response results indicated (4S, 5S)-(-)-HTZ exhibited higher toxic effects on earthworms than (4R, 5R)-(+)-HTZ. Finally, significant differentially expressed genes (DEGs) were observed in earthworms after exposure to (4R, 5R)-(+)-HTZ and (4S, 5S)-(-)-HTZ, respectively. These DEGs were mainly enriched in glycolysis/gluconeogenesis and purine metabolism pathways in earthworms. Additionally, six metabolism pathways were also enriched, including pyruvate metabolism, fatty acid biosynthesis, oxidative phosphorylation, citric acid cycle, fatty acid degradation, and ATP-binding cassette transporters. These findings suggest that earthworms exhibited enantiomer-specific responses to (4R, 5R)-(+)-HTZ and (4S, 5S)-(-)-HTZ. This study provides systemic insight into the toxicity mechanism of HTZ at the enantiomer level and the potential to develop (4R, 5R)-(+)-HTZ as a high-efficiency and low-risk pesticide.
