Excessive fat accumulation,viral infections and sustained inflammatory responses caused by non-alcoholic and alcoholic factors can contribute to liver inflammation,fibrosis and carcinogenesis,promoting the development of chronic liver disease.Gaining an in-depth understanding of the etiologic factors and underlying mechanisms that lead to chronic liver disease can help identify potential therapeutic targets for targeted therapy.Lactate,as an important substance in hepatic metabolism,has been found to be involved in the process of chronic liver disease through various pathways,and this review will provide a useful reference for the prevention and treatment of chronic liver disease.

Objectives:To evaluate the effectiveness of functionalized decellularized extracellular matrix(F-dECM)prepared from porcine auricular cartilage or porcine rib cartilage in repairing xenogeneic articular osteochondral defects.Methods:The por-cine auricular cartilage and rib cartilage were crushed and decellularized.Heparin modification and multi-factor loading were a-chieved through amide bond reaction.The physical characteristics of the particles were characterized by SEM observation and mer-cury intrusion.The chemical characteristics of the particles were characterized by tissue section staining and kit detection.The rabbit knee joint full-thickness defect models were established and implanted by different particles respectively.After 6 weeks and 12 weeks of operation,the samples were taken for gross observation,CT scanning and tissue sectioning to comprehensively evaluate the repair effect.Results:After heparin modification,the glycosaminoglycan lost during the decellularization process was replen-ished.Both heparinized auricular cartilage and costal cartilage presented a highly developed porous structure.Among them,the porosity and pore diameter of costal cartilage were both lower than those of auricular cartilage(P＜0.05).During the observation periods of 6 weeks and 12 weeks,the porcine costal cartilage F-dECM implantation group was superior to other experimental groups in knee joint repair effects(P＜0.05).Conclusion:Costal-derived F-dECM is a joint osteochondral defect repair material with application potential.

Objective:To observe the efficacy of thrombectomy combined with ezetimibe and atorvastatin in patients with acute ischemic stroke (AIS) and the serum levels of absent in melanoma 2 (AIM2) and leukotriene B4 (LTB4).Methods:A prospective study method was used to select 60 patients with AIS thrombectomy treated in Marina Bay Central Hospital of Dongguan City from June 2021 to December 2022, and they were divided into two groups according to random number table method, with 30 cases in each group. The control group was given atorvastatin treatment, and the study group was combined with ezetimibe treatment on the basis of the control group treatment. Blood routine indexes, blood lipid indexes and serum levels of AIM2 and LTB4 were compared between the two groups at admission, discharge and follow-up for 3 months. The National Institutes of Health Stroke Scale (NIHSS) was used to assess the degree of neurological impairment of the patients, and the modified Rankin Scale (mRS) was used to assess the patients' ability to live independently. The occurrence of adverse reactions in the two groups was observed and compared.Results:The neutrophil to lymphocyte ratio (NLR) and neutrophil (N) in the study group were lower than those in the control group : 1.71 ± 0.05 vs. 2.04 ± 0.31, 0.261 ± 0.012 vs. 0.403 ± 0.021 at follow-up for 3 months, there were statistical differences ( P<0.05). The levels of low density lipoprotein cholesterol (LDL-C), total cholesterol (TC) and triacylglycerol (TG) in the study group were lower than those in the control group at follow-up for 3 months:(1.59 ± 0.48) mmol/L vs. (2.09 ± 0.69) mmol/L, (2.92 ± 0.44) mmol/L vs. (3.57 ± 0.71) mmol/L, (1.19 ± 0.24) mmol/L vs. (1.37 ± 0.21) mmol/L, the level of high density lipoprotein cholesterol (HDL-C) was higher than that in the control group : (1.24 ± 0.19) mmol/L vs. (1.06 ± 0.21) mmol/L, there were statistical differences ( P<0.05). The levels of AIM2 and LTB4 in the study group were lower than those in the control group at discharge and follow-up for 3 months: (945.20 ± 123.60) ng/L vs. (1 094.40 ± 227.10) ng/L, (948.90 ± 135.80) ng/L vs. (1 236.90 ± 125.70) ng/L, (115.80 ± 20.60) ng/L vs. (129.70 ± 31.50) ng/L, (116.40 ± 21.10) ng/L vs. (130.30 ± 32.60) ng/L, there were statistical differences (P<0.05). The NHISS scores in the study group was lower than that in the control group at follow-up for 3 months: 2.00(1.00, 3.00) scores vs. 4.00(3.00, 5.00) scores, there was statistical difference ( P<0.05). After follow-up for 3 months, the mRS scores and incidence of adverse reactions between the two groups had no statistical differences ( P<0.05). Conclusions:The combination of atorvastatin and ezetimibe in the early stage of AIS thrombectomy can significantly reduce the levels of NLR, serum AIM2 and LTB4, improve blood lipid levels, reduce the degree of neurological impairment, and improve the ability of patients to carry out activities of daily living, with high safety.

In 2019, Staphylococcus aureus and Klebsiella pneumoniae were detected, with a pass rate of 86.7%. In 2021, Sendai virus antibodies were detected, yielding a pass rate of 85.7%.The pass rate in 2020, 2022, and 2023 was 100%. Rats: In 2017, positive results were found for helminths, mycoplasma antibodies, Staphylococcus aureus, Sendai virus antibodies, murine pneumonia virus antibodies, rat parvovirus RV strain antibodies, rat parvovirus (H-1) strain antibodies, and rat coronavirus antibodies, with a pass rate of 40.0%. In 2019, mycoplasma antibodies, Staphylococcus aureus and Klebsiella pneumoniae were detected, with a pass rate of 35.0%. No positive indicators were detected in 2020. In 2021, Sendai virus antibodies and rat parvovirus RV strain antibodies were detected, with a pass rate of 50.0%. In 2022, positive results for rat parvovirus RV strain antibodies were found, yielding a pass rate of 87.5%. In 2023, Pasteurella pneumotropica and Klebsiella pneumoniae were detected, with a pass rate of 85.7%. Dogs: In 2017 and 2019, the antibody titers for rabies virus and canine distemper virus were below the required standard, with pass rates of 33.3% and 20.0%, respectively. In 2020 and 2022, the pass rate was 100%. Guinea pigs (general grade): In 2019, positive results for Toxoplasma antibodies were detected, with a pass rate of 80.0%. In all other years, the pass rate was 100%. Monkeys: In 2019, positive results for Toxoplasma gondii and rhesus herpesvirus type I antibodies were found, with a pass rate of 87.5%.In 2020 and 2022, rhesus herpesvirus type I antibodies were positively detected, yielding pass rates of 93.3% and 97.5%, respectively. The pass rates in 2021 and 2023 were 100%. Clean guinea pigs, rabbits and pigs all passed the inspection each year. ConclusionIssues related to the parasitic and microbial quality of laboratory animals persist in Sichuan Province. Supervision and sampling inspections have proven to be effective in identifying these issues promptly, serving as a critical measure to ensure the quality of laboratory animals. The results of these inspections offer valuable data to support the healthy development of the laboratory animal industry in Sichuan Province.
