The majority of myasthenia gravis patients have detectable antibodies in their serum, targeting acetylcholine receptor, muscle-specific kinase, or related proteins. Current treatment for myasthenia gravis involves symptomatic therapy, immunosuppressive drugs such as corticosteroids, azathioprine, and mycophenolate mofetil, and thymectomy, which is primarily indicated in patients with thymoma or thymic hyperplasia. However, this condition continues to pose significant challenges including an unpredictable and variable disease progression, differing response to individual therapies, and substantial longterm side effects associated with standard treatments(including an increased risk of infections, osteoporosis, and diabetes), underscoring the necessity for a more personalized approach to treatment. Furthermore, about fifteen percent of patients, called “refractory myasthenia gravis patients”, do not respond adequately to standard therapies. In this context, the introduction of molecular therapies has marked a significant advance in myasthenia gravis management. Advances in understanding myasthenia gravis pathogenesis, especially the role of pathogenic antibodies, have driven the development of these biological drugs, which offer more selective, rapid, and safer alternatives to traditional immunosuppressants. This review aims to provide a comprehensive overview of emerging therapeutic strategies targeting specific immune pathways in myasthenia gravis, with a particular focus on preclinical evidence, therapeutic rationale, and clinical translation of B-cell depletion therapies, neonatal Fc receptor inhibitors, and complement inhibitors.展开更多

Traditional Chinese Medicine(TCM) has proven effective in treating PSD through syndrome differentiation, yet existing animal models primarily reflect Western medical concepts and fail to incorporate the TCM principle of “同病异治”( treating the same disease with different methods). This paper provides a review of the current methods for constructing animal models of post-stroke depression(PSD) from the perspective of Traditional Chinese Medicine(TCM) syndrome differentiation and proposes multi-dimensional assessment indicators. By integrating TCM theories with modern biomedical techniques, this study offers a comprehensive framework for deepening the understanding of the pathogenesis and therapeutic evaluation of PSD. This approach not only contributes to advancing PSD research but also paves the way for innovative treatment strategies that combine traditional and modern medicine.展开更多

文摘This study demonstrates a novel integration of large language models,machine learning,and multicriteria decision-making to investigate self-moderation in small online communities,a topic under-explored compared to user behavior and platform-driven moderation on social media.The proposed methodological framework(1)utilizes large language models for social media post analysis and categorization,(2)employs k-means clustering for content characterization,and(3)incorporates the TODIM(Tomada de Decisão Interativa Multicritério)method to determine moderation strategies based on expert judgments.In general,the fully integrated framework leverages the strengths of these intelligent systems in a more systematic evaluation of large-scale decision problems.When applied in social media moderation,this approach promotes nuanced and context-sensitive self-moderation by taking into account factors such as cultural background and geographic location.The application of this framework is demonstrated within Facebook groups.Eight distinct content clusters encompassing safety,harassment,diversity,and misinformation are identified.Analysis revealed a preference for content removal across all clusters,suggesting a cautious approach towards potentially harmful content.However,the framework also highlights the use of other moderation actions,like account suspension,depending on the content category.These findings contribute to the growing body of research on self-moderation and offer valuable insights for creating safer and more inclusive online spaces within smaller communities.

文摘Rural domestic sewage treatment is critical for environmental protection.This study defines the spatial pattern of villages from the perspective of rural sewage treatment and develops an integrated decision-making system to propose a sewage treatment mode and scheme suitable for local conditions.By considering the village spatial layout and terrain factors,a decision tree model of residential density and terrain type was constructed with accuracies of 76.47%and 96.00%,respectively.Combined with binary classification probability unit regression,an appropriate sewage treatment mode for the village was determined with 87.00%accuracy.The Analytic Hierarchy Process(AHP),combined with the Technique for Order Preference(TOPSIS)by Similarity to an Ideal Solution model,formed the basis for optimal treatment process selection under different emission standards.Verification was conducted in 542 villages across three counties of the Inner Mongolia Autonomous Region,focusing on the standard effluent effect(0.3773),low investment cost(0.3196),and high standard effluent effect(0.5115)to determine the best treatment process for the same emission standard under different needs.The annual environmental and carbon emission benefits of sewage treatment in these villages were estimated.This model matches village density,geographic feature,and social development level,and provides scientific support and a theoretical basis for rural sewage treatment decision-making.

文摘Human herpesvirus,a specific group within the herpesvirus family,is responsible for a variety of human diseases.These viruses can infect humans and other vertebrates,primarily targeting the skin,mucous membranes,and neural tissues,thereby signifi-cantly impacting the health of both humans and animals.Animal models are crucial for studying virus pathogenesis,vaccine development,and drug testing.Despite several vaccine candidates being in preclinical and clinical stages,no vaccines are current available to prevent lifelong infections caused by these human herpesviruses,except for varicella-zoster virus(VZV)vaccine.However,the strict host tropism of herpes-viruses and other limitations mean that no single animal model can fully replicate all key features of human herpesvirus-associated diseases.This makes it challeng-ing to evaluate vaccines and antivirals against human herpesvirus comprehensively.Herein,we summarize the current animal models used to study the human herpesvi-ruses includingα-herpesviruses(herpes simplex virus type 1(HSV-1),HSV-2,VZV),β-herpesviruses(human cytomegalovirus(HCMV),γ-herpesviruses(Epstein-Barr virus(EBV))and Kaposi's sarcoma herpesvirus(KSHV)).By providing concise information and detailed analysis of the potential,limitations and applications of various models,such as non-human primates,mice,rabbits,guinea pigs,and tree shrews,this sum-mary aims to help researchers efficiently select the most appropriate animal model,offering practical guidance for studying human herpesvirus.

文摘The application of generative artificial intelligence(AI)is bringing about notable changes in anime creation.This paper surveys recent advancements and applications of diffusion and language models in anime generation,focusing on their demonstrated potential to enhance production efficiency through automation and personalization.Despite these benefits,it is crucial to acknowledge the substantial initial computational investments required for training and deploying these models.We conduct an in-depth survey of cutting-edge generative AI technologies,encompassing models such as Stable Diffusion and GPT,and appraise pivotal large-scale datasets alongside quantifiable evaluation metrics.Review of the surveyed literature indicates the achievement of considerable maturity in the capacity of AI models to synthesize high-quality,aesthetically compelling anime visual images from textual prompts,alongside discernible progress in the generation of coherent narratives.However,achieving perfect long-form consistency,mitigating artifacts like flickering in video sequences,and enabling fine-grained artistic control remain critical ongoing challenges.Building upon these advancements,research efforts have increasingly pivoted towards the synthesis of higher-dimensional content,such as video and three-dimensional assets,with recent studies demonstrating significant progress in this burgeoning field.Nevertheless,formidable challenges endure amidst these advancements.Foremost among these are the substantial computational exigencies requisite for training and deploying these sophisticated models,particularly pronounced in the realm of high-dimensional generation such as video synthesis.Additional persistent hurdles include maintaining spatial-temporal consistency across complex scenes and mitigating ethical considerations surrounding bias and the preservation of human creative autonomy.This research underscores the transformative potential and inherent complexities of AI-driven synergy within the creative industries.We posit that future research should be dedicated to the synergistic fusion of diffusion and autoregressive models,the integration of multimodal inputs,and the balanced consideration of ethical implications,particularly regarding bias and the preservation of human creative autonomy,thereby establishing a robust foundation for the advancement of anime creation and the broader landscape of AI-driven content generation.

文摘Photodynamic therapy(PDT)is an emerging minimally invasive therapeutic modality that relies on the activation of a photosensitizing agent by light of a specific wavelength in the presence of molecular oxygen,leading to the generation of reactive oxygen species(ROS).This mechanism facilitates selective cytotoxic effects within pathological tissues and has demonstrated therapeutic potential across diverse disease contexts.However,the broader clinical applications remain limited by photosensitizer selectivity,shallow light penetration,and the risk of off-target cytotoxicity.Recent advancements in PDT have focused on the development of next-generation photosensitizers,the integration of nanotechnology for enhanced delivery and targeting,and the strategic combination of PDT with complementary therapeutic approaches.Experimental animal models play a crucial role in validating the efficacy and safety of PDT,optimizing its therapeutic parameters,and determining its mechanisms of action.This review provides a comprehensive overview of PDT applications in various disease models,including oncological,infectious,and nonconventional indications.Special emphasis is placed on the importance of large animal models in PDT research,such as rabbits,pigs,dogs,and non-human primates,which provide experimental platforms that more closely resemble human physiological and pathological states.The use of these models for understanding the mechanisms of PDT,optimizing therapeutic regimens,and evaluating clinical outcomes is also discussed.This review aims to inform future directions in PDT research and emphasizes the importance of selecting appropriate preclinical animal models to facilitate successful clinical translation.

文摘Lung cancer has one of the highest rates of incidence and mortality worldwide,mak-ing research on its mechanisms and treatments crucial.Animal models are essential in lung cancer research as they accurately replicate the biological characteristics and treatment outcomes seen in human diseases.Currently,various lung cancer models have been established,including chemical induction models,orthotopic transplan-tation models,ectopic transplantation models,metastasis models,and gene editing mouse models.Additionally,lung cancer grafts can be categorized into two types:tissue-based and cell-based grafts.This paper summarizes the phenotypes,advan-tages,and disadvantages of various induction methods based on their modeling tech-niques.The goal is to enhance the simulation of clinical lung cancer characteristics and to establish a solid foundation for future clinical research.
文摘Rotator cuff tears are highly prevalent,and there is an urgent need to understand their healing mechanisms to improve treatment outcomes for patients.This editorial aims to summarize the roles and limitations of common animal models(including rodents,rabbits,sheep,dogs,and primates)and second-look arthroscopy in rotator cuff healing research.Different animal models offer distinct advantages and disadvantages.For example,rodent models are cost-effective and suitable for genetic studies but have anatomical differences from humans.Rabbit models are favored for their relatively large tendon size and ease of surgical manipulation,yet they still deviate from human shoulder anatomy in some aspects.Larger animals like sheep and dogs have more similar shoulder structures to humans but come with high costs and challenges in maintaining consistent experimental conditions.Second-look arthroscopic studies have provided evidence for the effectiveness of current surgical techniques.Animal models will continue to play a crucial role in further exploring the local microenvironment of the rotator cuff,which is expected to help develop more effective strategies to promote healing.

文摘Post-stroke depression(PSD) is a common psychiatric complication affecting nearly one-third of stroke survivors, leading to increased disability, mortality, and cognitive decline. Traditional Chinese Medicine(TCM) has proven effective in treating PSD through syndrome differentiation, yet existing animal models primarily reflect Western medical concepts and fail to incorporate the TCM principle of “同病异治”( treating the same disease with different methods). This paper provides a review of the current methods for constructing animal models of post-stroke depression(PSD) from the perspective of Traditional Chinese Medicine(TCM) syndrome differentiation and proposes multi-dimensional assessment indicators. By integrating TCM theories with modern biomedical techniques, this study offers a comprehensive framework for deepening the understanding of the pathogenesis and therapeutic evaluation of PSD. This approach not only contributes to advancing PSD research but also paves the way for innovative treatment strategies that combine traditional and modern medicine.

文摘The mortality rate of patients with abdominal aortic aneurysm(AAA) after rupture is extremely high,and this disease has become an important disease endangering the health of the Chinese population.Methods used to model AAA include intraluminal pressurized elastase infusion,chronic infusion of angiotensin Ⅱ(Ang Ⅱ) via an osmotic pump,periarterial application of calcium chloride,vascular grafting,and gene modification.AAA models induced by elastase and Ang Ⅱ are the two most widely used animal models.In the elastase-induced model,because intraluminal infusion is transient,with the cessation of initial stimulation,the aneurysm lesion tends to be stable and rarely ruptures.The model induced by Ang Ⅱ infusion often presents with a typical aortic dissection with a false lumen,whereas clinical AAA patients do not necessarily have dissection.Currently,the treatment of AAA in clinical practice remains endovascular,and there is a lack of pharmacological therapy,which is also related to the fact that the pathogenic mechanism has not been fully elucidated.Smoking,old age,male sex,and hypertension are the main risk factors for AAA,but these risk factors have not been fully investigated in the current modeling methods,which may affect the clinical translational application of research results based on animal models.Therefore,this article reviews the most commonly used AAA modeling methods,comments on their applications and limitations,and provides a perspective on the development of novel animal models.
