Hepatic alveolar echinococcosis is a highly invasive zoonotic parasitic disease with poor prognosis. Surgical intervention serves as the pivotal approach to achieve radical cure and improve the prognosis of hepatic alveolar echinococcosis patients. In recent years, with the popularization of the concept of precision surgery and the development of the multidisciplinary diagnosis and treatment model, the surgical treatment strategies for hepatic alveolar echinococcosis have been continuously enriched, and the selection of surgical procedures has become increasingly diversified. Although key surgical techniques such as radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation have achieved remarkable progress in clinical application, many insurmountable challenges still remain. Therefore, by sorting out the latest evidence-based advances in the field of surgical treatment for hepatic alveolar echinococcosis, this article focuses on discussing the application status and bottlenecks of radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation in hepatic alveolar echinococcosis, aiming to provide a reference for the clinical treatment of hepatic alveolar echinococcosis.

ObjectiveTo meet the requirements of Good Laboratory Practice (GLP), Sichuan Institute for Drug Control (Sichuan Testing Center of Medical Devices, Sichuan Institute of Musk Deer Breeding) Safety Evaluation Center (hereinafter referred to as the center) conducts a targeted validation study to address the lack of supporting data for the specified validity periods of disinfectants, feed, and bedding during their use in laboratory animal facilities. The study summarizes practical experience in material management and provides a scientific basis for the standardized management of materials in the facility. MethodsUnder the routine operating conditions of the laboratory animal facility at the center, the disinfection efficacy of four commonly used disinfectants was confirmed using the quantitative suspension kill test, with the disinfectants tested on day 0, day 7, and at 1, 2, and 3 months after preparation and after opening; for laboratory animal feed, nutritional components, chemical contaminants, and microbial indicators were tested 7 days after opening; microbial indicators of laboratory animal corncob bedding were tested after storage for 7 days following opening and sterilization. ResultsUnder the GLP management system of our center, the disinfection efficacy log reduction values of prepared 0.04% sodium hypochlorite solution, 0.1% didecyldimethylammonium bromide solution, and 0.2% benzalkonium bromide solution were all ≥5 on days 0 and 7. The log reduction values of opened 75% ethanol were ≥5 on days 0 and 7 and at 1, 2, and 3 months after opening. All disinfectants were therefore qualified and effective. Compared with the factory inspection data, the nutritional components, chemical contaminants, and microbial indicators of SPF-grade rat and mouse maintenance feed, SPF-grade guinea pig growth and reproduction feed, conventional-grade guinea pig growth and reproduction feed, rabbit maintenance feed, and dog maintenance feed showed a slight overall downward trend but no significant differences 7 days after opening. The microbial indicators of specialized corncob bedding for SPF-grade laboratory animals stored for 7 days after opening and conventional-grade corncob bedding stored for 7 days after sterilization showed no significant fluctuations. All indicators still met the relevant requirements of GB/T 14924.2—2001 Laboratory Animals—Hygienic Standard for Formula Feeds and GB 14924.3—2010 Laboratory Animals—Nutrients for Formula Feeds. ConclusionBased on practical experience in managing the center's GLP laboratory animal facility and validation of core quality indicators, the specified validity periods of disinfectants, feed, and bedding meet the quality requirements, providing a practical reference for the standardized management of laboratory animal facilities.

The specific mechanisms of interferon regulatory factor 8(IRF8)in porcine intestinal in-nate immunity and resistance to enteric virus infection remain to be elucidated.To investigate the immunoregulatory role of IRF8,establishing an IRF8 gene knockout porcine intestinal epithelial cell(IPEC-J2)monoclonal cell line is of significant importance.This study initially aimed to obtain recombinant adeno-associated virus rAAV-sgIRF8-eGFP capable of knocking out the IRF8 gene through co-transfection of HEK-293T cells with three plasmids.Subsequently,IPEC-J2 cells were infected with the virus,and those expressing eGFP were selected by flow cytometry and cultured to form monoclonal cell lines.These cell lines were then identified by Sanger sequencing and West-ern blot techniques.Lastly,qPCR analysis was used to measure the expression levels of interferon factors IFN-α,IFN-β,IFN-γ and IFN-λ,providing preliminary insights into the impact of IRF8 gene knockout on IPEC-J2 cell immunity.The results demonstrated successful generation of rAAV-sgIRF8-eGFP,which successfully infected IPEC-J2 cells leading to eGFP fluorescence.Flow cytometry followed by cell culture led to the establishment of two monoclonal cell lines,IRF8-KO1 and IRF8-KO3.Sanger sequencing revealed a five-base deletion in IRF8-KO1 and a seven-base dele-tion in IRF8-KO3.Western blot confirmed the absence of IRF8 protein expression in IRF8-KO1,making it an ideal candidate monoclonal cell line.qPCR analysis of interferon factors indicated sig-nificant decrease in IFN-γ(P<0.05)and IFN-λ(P<0.01)transcription level in IRF8-knockout cells,while the transcription levels of IFN-α and IFN-β remained relatively unchanged.This study successfully established an IRF8 gene knockout IPEC-J2 monoclonal cell line,providing a founda-tion for further research on IRF8-related porcine intestinal immune regulation and mechanisms of intestinal virus infection.
