Genetically modified pigs for welfare assurance is crucial for conducting xenotransplantation. However, traditional experimental animal ethics principles cannot address the social benefits issues brought about by xenotransplantation, and there is a lack of ethical justification for the assurance of experimental animal welfare. Degrazia and Bechtel proposed six principles for the welfare of experimental animals: the principle of no alternative methods, the principle of expected net benefits, the principle of adequate defense of harm, the principle of no harm without necessity, the principle of basic needs and the principle of harm limit. This paper conducts an ethical-level argumentation on the six principles for the welfare of genetically modified pigs in xenotransplantation, and points out that these six principles are of great significance in closely integrating the social benefits of xenotransplantation with the welfare of genetically modified pigs, emphasizing the moral status of genetically modified pigs, and providing standards for the ethical review of the welfare of genetically modified pigs.

The MGF300-4L protein of African swine fever virus(ASFV),a virulence-associated fac-tor,degrades IKKβ through the chaperone-mediated autophagy and enhances the stability of IKBαto suppress the generation of IL-1β and TNF-α regulated by the NF-κB signaling pathway.To iden-tify the host proteins interacting with MGF300-4L,PK-15 cells were transfected with the eukary-otic plasmid expressing MGF300-4L and analyzed using immunoprecipitation-mass spectrometry(IP-MS)to identify the host proteins that interact with MGF300-4L.Additionally,gene ontology(GO)and KEGG pathway enrichment analyses were conducted.Furthermore,molecular docking a-nalysis,co-immunoprecipitation,and laser confocal microscopy assays were performed to validate the host proteins interacting with MGF300-4L.The IP-MS analysis identified 145 host proteins that potentially interact with MGF300-4L.Subsequent GO and KEGG pathway enrichment analy-ses revealed that these proteins are predominantly involved in metabolic,cellular,and innate immune responses.Through molecular docking prediction,co-immunoprecipitation assay,and laser confocal microscopy,we identified the interaction between MGF300-4L and STAT1.This study provides critical insights into the mechanisms underlying the interactions between MGF300-4L and the host proteins.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

  Objective  To evaluate the severity and features of pelvic coronal plane tilt in individuals with adolescent idiopathic scoliosis (AIS) who had lumbar curvature during the gait cycle.  Methods  AIS patients with lumbar curvature and patients with microcurvature (Cobb Angle less than 10 degrees) treated in Peking Union Medical College Hospital from September 2020 to February 2023 were retrospectively included. According to PUMC conservative classification system and Spinal Full-length Standing X-ray, AIS patients with lumbar curvature were enrolled. The bilateral iliac crest was used as the bony marker of the pelvic coronal surface, and the bilateral iliac crest height and its changes were measured during the standing position and walking cycle, so as to evaluate the degree of pelvic coronal tilt in AIS patients with lumbar curvature.  Results  A total of 209 AIS patients with lumbar curvature and 36 patients with microcurvature who met the inclusion and exclusion criteria were enrolled. The proportion of AIS patients with lumbar curvature who had a "congruent" relationship between the higher iliac crest and the convex side of the spine in standing position (iliac crest lower on the convex side than on the concave side) was significantly higher in AIS patients with lumbar curvature than patients with microcurvature(58.9% vs. 30.6%, P=0.002). AIS patients with lumbar curvature had statistically different bilateral iliac crest height change values throughout the gait cycle (including minimum, maximum, swing phase minimum, and swing phase maximum) (all P < 0.001), and the iliac crest height change values on the convex side were significantly higher than those on the concave side (all P < 0.05), whereas the patients with microcurvature did not have any statistically significant bilateral iliac crest height change values throughout the gait cycle (all P > 0.05).  Conclusion  The height of the iliac crest on the convex side of the lumbar spine is lower than that on the concave side in the standing position of AIS patients with lumbar curvature, and the value of the change of the iliac crest on the convex side of the pelvis is greater than that on the concave side in walking to maintain the balance of the body, which may provide a new direction for the intervention in the clinical rehabilitation treatment of AIS patients with lumbar curvature.

As the backbone force of China's social and economic construction, the health status of workers is closely related to the nation's productivity and social development. Currently, cancers have become one of the major diseases threatening the health of workers. However, there are still many shortcomings in the cancer screening services for the workers. To standardize cancer screening services for workers, ensure the quality of screening services, and improve the overall screening effectiveness, 19 institutions, including Peking Union Medical College Hospital of the Chinese Academy of Medical Sciences, have jointly formulated the Group Standard "Specification for service of cancer screening for workers (T/CHAA 023-2023)". This standard follows the principles of "legality, scientific rigor, advancement, and feasibility" and combines the frontier scientific advances in cancer screening. It clarifies the relevant requirements for service principles, service design, service delivery, service management, service evaluation, and improving worker cancer screening. Implementing this group standard will help connect the common screening needs of workers, employers, and cancer screening service providers, standardize the screening process, improve screening quality, and ultimately increase the early diagnosis rate and survival rate of cancer patients. Consequently, this group standard will help safeguard workers' health rights and interests, ensure the labor force resources, promote the comprehensive coordinated and sustainable development of society, and contribute to realizing the "Healthy China 2030" strategic policy.

TCM believes that spleen deficiency is the root cause of emotional abnormalities in chronic fatigue syndrome (CFS), and clinical treatment often involves the heart, liver and kidney. TCM therapy has a significant efficacy in CFS emotional abnormalities. It is mostly treated with oral administration of TCM, acupuncture, moxibustion and massage therapy. It may play a therapeutic role by improving oxidative stress and immune inflammation, regulating nerve-endocrine, controlling energy metabolism and other ways. It is suggested to establish the syndrome differentiation standard of CFS emotional abnormality in the future, so as to improve the accuracy of syndrome differentiation and treatment; form a perfect treatment guide or expert consensus to guide the standardized application of various internal and external treatment methods; explore objective indicators based on the pathogenesis, and focus on the morphological and functional changes of disease target brain regions with the help of neuroimaging techniques, so as to improve the diagnosis and prognosis evaluation of CFS; based on the guidance of TCM theory, improve the CFS emotional abnormal animal modeling method.

Objective:To investigate the factors influencing recipient liver regeneration after full-size split liver transplantation (fSLT).Methods:The clinical data of patients undergoing split liver transplantation in the Affiliated Li Huili Hospital of Ningbo University from May 2019 to Sep 2023 were retrospectively collected. Graft volume (GV) and initial graft volume (IGV) at (30±7) days after operation were measured, and postoperative liver regeneration rate (LRR) was calculated. The patients undergoing fSLT were divided into high regeneration group and low regeneration group with LRR=30% as boundary. The differences of donor and recipient data and perioperative data between the two groups were compared.Results:A total of 52 patients were included. The low fSLT regeneration group (16 cases) was compared with the high fSLT regeneration group (36 cases), and in high fSLT regeneration group donor age was lower, the donor liver steatosis was less, GRWR was lower, the incidence of hepatitis B virus-related liver disease was lower, the postoperative diagnosis of malignant liver disease was lower, the intraoperative blood loss was less, and the postoperative platelet count was higher. The levels of liver enzyme and total bilirubin (TBiL) were higher than those in high regeneration group ( P<0.05). Conclusions:Donor age, donor liver steatosis, GRWR, hepatitis B virus associated liver disease, and recipient pathogenesis are important factors affecting liver regeneration after fSLT. Postoperative platelet and liver enzyme levels are important indicators for monitoring liver regeneration after fSLT.
