Study on Diagnosis of Fetal Chromosomal Abnormalities by Ultrasound Screening and Ultrasound-Guided Amniocentesis
type: item
description: With advancements in modern medical technology, prenatal diagnosis has become increasingly crucial. This review focuses on exploring the clinical value, application status, and research progress of two key prenatal diagnostic methods—ultrasound screening and ultrasound-guided amniocentesis—in the detection of fetal chromosomal abnormalities. By systematically summarizing relevant literature and clinical studies, the review analyzes the effectiveness, safety, and applicable scenarios of these two methods, compares their advantages and limitations with other common prenatal screening and diagnostic techniques, and identifies the core indications for their clinical application. The study reveals significantly higher detection rates of chromosomal abnormalities in the ultrasound screening abnormal group compared to the Down syndrome screening group. Key indications for amniocentesis include abnormal Down syndrome screening results, ultrasound screening abnormalities (such as NT thickening), and advanced maternal age. This research demonstrates the clinical significance of early pregnancy ultrasound screening in detecting fetal chromosomal abnormalities, while ultrasound-guided amniocentesis proves to be a safe and reliable diagnostic method.

Small RNAs in Bacterial Outer Membrane Vesicles
type: item
description: Outer membrane vesicles (OMVs) from Gram-negative bacteria exhibit selective enrichment for small RNAs (sRNAs), including tRNA fragments, as opposed to randomly reflecting cellular RNA pools. Building on well-established RNase-detergent controls and ddRTPCR quantification, we summarise delivery stoichiometry (≈1% of vesicle RNA reaching recipient cytoplasm) and propose reporting standards (vesicles per cell, RNA copies per vesicle, delivery per cell). Functionally, OMV RNAs signal via two main routes: cytosolic Argonaute-dependent silencing and endosomal TLR7/8 sensing in both pathogenic and commensal bacterial species. We highlight evidence that OMVs can travel along the gut–brain axis and activate astrocytic NF-κB, thereby exacerbating amyloidassociated pathology, and we outline the experimental controls needed to attribute these effects specifically to RNA cargo. Finally, we consider how these principles could guide the engineering of probiotic-derived OMVs to tune immune tone within a quantitative mechanistic framework. This review identifies key methodological gaps and puts forth quantitative frameworks for studying RNA delivery.

The Role of Single-Leg Vertical Jump in Return-to-Sport Evaluation After ACL Reconstruction — A Critical Review Based on Optical Motion Capture
type: item
description: Anter ior cruciate l igament (ACL) injuries and reconstruction surgeries are very common in sports medicine. Scientific evaluation and documentation of return-to-sport (RTS) readiness are key steps to reduce the risk of re-injury. This paper builds on research published in the British Journal of Sports Medicine (2022), explaining the use of optical motion capture in evaluating functional performance after ACL reconstruction. The study found that while horizontal hop tests often appear symmetrical, the single-leg vertical jump (SLJ) more effectively reveals deficits in knee joint function. This review summarizes the contributions of the research, critically analyzes its limitations, and proposes directions for future improvement. In addition, ACL injuries are common in sports requiring single-leg deceleration, cutting, and landing movements, such as basketball, soccer, handball, and skiing, with most being non-contact injuries. As competition levels rise, ACL injuries and reconstructions are increasingly frequent, highlighting the necessity of establishing sensitive and reproducible RTS evaluation indicators.

A Review of the Effects of ApoE3 and the Principle of Treating Alzheimer’s Disease
type: item
description: The onset of Alzheimer ’s disease is related to genetics, abnormal deposition of beta amyloid (Aβ), hyperphosphorylation of Tau protein, neuroinflammation, oxidative stress, neurotransmitter disorders, age and other factors. In recent years, the global population aging has intensified, and the prevalence of Alzheimer’s disease has continued to rise. It is estimated that the number of patients around the world will reach 78 million by 2030. This paper starts with the polymorphism of the genetic pathogenic gene of Alzheimer’s disease, apolipoprotein E (ApoE), breaks the previous research inertia that focused solely on the “pathogenic mechanism” of ApoE4, and discusses some pathogenic genes in Alzheimer’s disease by focusing on the specific blocking effect of ApoE3 R136S mutation on tau pathology. From molecular mechanisms, cellular models, and animal experiments to clinical translation, this paper demonstrates that the ApoE3 R136S mutation exerts a neuroprotective effect against AD through multiple pathways, including inhibiting tau propagation, regulating immune responses, and promoting tau degradation.

description: Alzheime r ’s d i s e a s e ( A D ) i s a p r o g r e s s i v e neurodegenerative disorder. With population aging, its incidence rises continuously, imposing a heavy burden on society. Currently, relevant drugs can only alleviate disease progression but cannot achieve a complete cure, which urgently calls for in-depth research on AD pharmacological treatments. This paper conducts a comprehensive review, a gap that urgently necessitates in-depth research into AD pharmacological treatments. It provides an overview of AD and its current treatment landscape, involving the disease’s status, the efficacy evaluation of pharmacotherapies, and the core value and significance of pharmacotherapy in AD intervention. Then, it explores AD’s pathogenesis and pharmacotherapeutic targets. Additionally, the efficacy and safety of AD drug therapies are analyzed. Finally, limitations and challenges in current AD research are discussed. Through this study, it is concluded that although there are some advances in AD pharmacological treatments, there remains a long path to achieving a complete cure and further exploration of disease mechanisms and innovative drug development is therefore essential.

Application and Prospect of Stem Cells and Biomaterials in Oral and Maxillofacial Tissue Regeneration
type: item
description: Oral and maxillofacial soft tissue defects are common clinical problems that seriously affect patients’ oral function and mental health. Traditional restorative methods have limitations, while regenerative dentistry utilizes oral-derived Mesenchymal Stem Cells (MSCs), such as Dental Pulp Stem Cells (DPSCs), Periodontal Ligament Stem Cells (PDLSCs), and Stem Cells from Human Exfoliated Deciduous Teeth (SHED), combined with biomaterials such as hydrogels, scaffolds, and growth factors, to provide a new strategy for tissue regeneration. This type of stem cell exhibits multidirectional differentiation capacity and can promote the functional repair of dentin, periodontal, and bone tissues. In recent years, cell-free strategies based on the MSCs secretum (such as exosomes and conditioned medium) have also shown regenerative potential. Although challenges remain in MSC sources, vascularization, and material integration, with the advancement of tissue engineering technology and personalized treatment, regenerative dentistry holds broad prospects for the repair of oral and maxillofacial defects.

CAR-T Cell Therapy in Primary Mediastinal B-cell Lymphoma
type: item
description: A specific type of CAR-T cell therapy, the CAR19 therapy has demonstrated notable efficacy for relapsed or refractory (R/R) hematologic cancers, including B-cell lymphomas. After the recent reclassification of the rare subtype Primary Mediastinal B-cell Lymphoma (PMBCL) from general Diffuse Large B-cell Lymphoma (DLBCL), questions have been raised about the application of immunotherapies in this cancer, including the most discussed CAR-T cell therapy. The CAR-T cell therapy, more specifically the CAR19, exerts anti-tumor effects in multiple mechanisms, including different cytotoxic pathways—apoptosis triggering via perforin–granzyme release and Fas/FasL-pathway—driven by calcium-dependent signaling MAPK, PI3K/Akt, and NF-κB. Multiple extant clinical trials have evaluated the response of PMBCL patients to CAR19, specifically the Axi-cel, Liso-cel, and Tisa-cel therapies, focusing the rates of complete response (CR), progression-free survival (PFS), and the overall survival (OS). Studies exclusive to PMBCL patients showed that bridging therapies and other first-line treatments did not influence CAR19 effectiveness, while post-relapse application of Pembrolizumab yielded durable CRs in some patients, and allo-HSCT was associated with high mortality. The CAR-SIE trial in Italy, comparing Axi-cel CAR19 in PMBCL cancer with other B-cell lymphomas, demonstrated a better result in PMBCL patients with higher ORR, CR, and PFS. This paper integrates the underlying mechanisms of CAR19 with clinical trials, aiming to demonstrate both the potential and the limitations of this therapy in PMBCL cancer.

type: item
description: Single-nucleotide polymorphisms (SNPs) are the most common type of variation in the human genome and crucial biomarkers for assessing susceptibility to disease, response to pharmacological intervention. Conventional methods of SNP detection, including Sanger sequencing, polymerase chain reaction (PCR), and microarray analysis, have been widely used; however, these are limited with regards to throughput, scalability, and point-of-care compatibility. Alternatively, nanopore-based sequencing technologies are new platforms, enabling real-time, label-free analysis at the single-molecule level. This review outlines the recent developments in the application of biological, solid-state, and hybrid nanopores as devices for SNP detection, focusing on their fundamental principles, highlights of notable platforms, and technological developments. Key milestones include advancements in sample preparation and translocation control, signal resolution optimization through geometric pore design and the use of ultrathin membranes, and the development of probe engineering strategies targeting allele-specific discrimination as well as minimizing background noise. These advances aim to improve the accuracy and clinical relevance of nanopore-mediated SNP detection, and the translational significance of precision medicine.

Application of Artificial Intelligence in the Design of Tumor mRNA Vaccines
type: item
description: For many years, scientists have been focused on developing mRNA-based vaccines, an area that has transitioned from theoretical concepts to practical treatments in clinical settings. This remarkable progress highlights the speed at which scientific advancements can occur when collaboration and innovation intersect. mRNA vaccines offer several inherent advantages, such as robust immunogenicity, a lack of gene integration risks, and the potential for cost-effective production. However, challenges related to mRNA stability and degradation continue to pose significant hurdles. To address these challenges and enhance vaccine development, traditional trial-and-error methods are increasingly being complemented and, in some cases, replaced by rational design strategies that leverage artificial intelligence (AI). In this review, we explore the core technologies underpinning mRNA vaccines and discuss how AI-driven design methods are optimizing their development. We also present a case study of trRosettaRNA, a deep learning-based approach for automating the prediction of RNA three-dimensional structures. This method successfully predicts the 3D structure of target RNA, demonstrating the transformative potential of AI in optimizing vaccine design and further advancing mRNA-based therapeutic strategies.

Application of CRISPR in the Treatment of Pancreatic Cancer
type: item
description: As a highly invasive malignant tumor, pancreatic cancer (PC) has an increasing incidence rate and a long-term low 5-year survival rate. At present, CRISPR has been used in the research of PC to analyze the function of oncogenes, explore drug resistance mechanisms and develop treatment strategies. Most of them are in the stage of cell and animal experiments. However, there are still research gaps in tumor microenvironment penetration, low delivery efficiency in vivo, off target effects and treatment limitations caused by tumor heterogeneity. This article systematically reviews the CRISPR foundation, analyzes the pathogenesis of high-frequency mutant genes in PC, elaborates three major treatment strategies based on CRISPR, combs the progress of second-generation CRISPR, clarifies the current technical challenges, and proposes targeted vector development, high fidelity Cas protein application and other corresponding programs. This study provides a comprehensive reference for the clinical transformation of CRISPR in the field of PC, helping to break through the bottleneck of traditional treatment; However, the long-term safety of this technology in the human body still needs to be verified. Future research can rely on the third-generation CRISPR to optimize the targeted delivery system, explore the joint strategy with immunotherapy and chemotherapy, promote the technology to clinical implementation, and provide more accurate treatment schemes for PC patients.

type: item
description: The rapid development of CRISPR gene editing has brought revolutionary breakthroughs to the biomedical area, yet the design of gRNA is still facing problems as unstable editing efficiency and the risk of off-target. The introduction of Artificial Intelligence (AI) technology has guided this issue to a brighter future. Studies have shown that deep learning models can predict editing efficiency and assess off-target risk precisely through analyzing information as the sequence features of gRNA, while the introduction of tools like Reinforcement Learning (RL) further enlarges the space of gRNA design. There is still a deficiency in recent studies. This paper analyzes the application of AI in gRNA design, including editing efficiency and off-target risk assessment. The workflow, performance, and limitations of each model are concluded, and the conclusion of AI having a great devotion to gRNA design and the tips for choosing different models in different cases are given. This research provides references about choosing and designing models, but there are still unsolved challenges in aspects of building standard datasets and public databases. In the future, gRNA design can be optimized by reinforcing the use of Federated Learning (FL) and single-cell CRISPR screening technology.

Research Progress on Molecular Mechanisms of Exercise-Regulated Immunity
type: item
description: Physical exercise exerts bidirectional effects on human immune system. This essay is written to demonstrate significant molecular mechanisms of the opposite immune regulations by physical activity. Epidemiologic evidence indicates that regular exercisers experience reduced risk of upper respiratory tract infections (URTIs) and exhibit substantially lower incidence rates of certain cancers. Inversely, athletes who have undergone intense physical training, such as those who have participated in a marathon race. The incidence rate of URTI will increase significantly compared to that of ordinary people who did not participate in the competition during the same period. Through comprehensive literature review and analysis, this review synthesizes current knowledge on exercise-immune interactions. Main findings indicate the J model theory curve relationship between exercise intensity and infection risk of URTIs, demonstrating that moderate activity enhances immunosurveillance while prolonged high-intensity exercises may induce temporary immunosuppression. This article clearly explains the classic cellular pathways of immune regulation, achieving a combination of the macroscopic and the microscopic. Serving as the scientific basis for individualized exercise prescriptions.

Principles and Methods of De Novo Protein Design and Applications
type: item
description: De novo protein design strategy enables to create novel protein sequence that are able to fold in stable and functional structure, while breaking through the limitation of natural evolution. This method, which is based on the idea that the amino acid sequence of a protein dictates its three-dimensional structure, identifies a particular sequence with a low-energy state by combining computational methods, molecular interaction modeling, and thermodynamic optimization. Stabilizing interactions between molecules are precisely engineered to ensure the protein is folded into desired structure, while maintaining conformational stability. Recent advanced methods in de novo protein design includes flexible and fixed backbone modeling and deep learning-guided assembly. These methods have improved accuracy of modeling and broadened available space for protein sequence. De novo protein design can be applied across multiple biomedical domains. De novo protein design achieves notable success in vaccine innovation, where stabilized epitopes are presented to enhance the immune targeting, and in immunotherapy, where synthetic cytokine mimetics achieve high selectivity with reduced toxicity. These developments demonstrate how de novo protein design is transitioning from a conceptual idea to a robust platform for advanced therapeutics.

type: item
description: With impressive clinical results, The management of hematologic malignancies has evolved as a result of CAR-T treatment. However, its application to solid tumors is restricted by immune-suppressive tumor milieus, antigenic heterogeneity, and insufficient persistence and infiltration of engineered T cells. CRISPR-Cas9, a versatile and precise genome-editing platform, offers new strategies to overcome these challenges through targeted modification of its products. This paper describes the mechanical properties and structural layout of CAR-T treatment, together with important obstacles in the context of solid tumors and CRISPR-driven engineering techniques meant to improve therapeutic efficacy. The development of universal CAR-T products for ready-to-use applications, metabolic reprogramming to adapt to nutrient-limited and hypoxic conditions, cytokine gene integration to support persistence and immune communication, and checkpoint receptor disruption to maintain T-cell activity are examples of representative strategies. Collectively, the convergence of CRISPR and CAR-T technologies enhances precision, durability, and broad applicability, positioning this combined strategy as a promising direction for next-generation immunotherapy against solid cancers.

The Impact of Nanoparticle-Modified Carriers on Drug Entry and Exit in Tumor Cells
type: item
description: In recent years, malignant tumors have posed a severe threat to human health. Currently, most clinically used drug molecules are non-targeted chemical structure drugs with low bioavailability. The halogens or sulfur elements in their structures can easily cause toxic side effects to normal cells. High doses are required to achieve therapeutic concentrations, which may further exacerbate toxic side effects and lead to non-specific adverse reactions. Additionally, the rapid excretion of drugs can easily cause peak and trough phenomena, resulting in poor therapeutic effects. In contrast, nanoparticle carriers wrapped in cell membranes have gained widespread application in cancer treatment due to their high biocompatibility. They can disguise themselves as autologous cells, evade recognition and clearance by the immune system, prolong circulation time in the bloodstream, and enhance targeting to tumors. This is crucial for tumor drug delivery and treatment.

Research on the Epidemiology of Zoonotic Diseases due to Overgrazing - Take Echinococcosis as an Example
type: item
description: Echinococcoccosis is a global zoonotic disease caused by Echinococcus granulosus and Echinococcus multilocularis, posing a serious threat to human health, livestock production and ecological balance. This review examines the epidemiological characteristics of echinococcosis, focusing on the amplifying role of overgrazing in disease transmission. Overgrazing disrupts grassland ecosystems and increases contact between wild canids (foxes, wolves), domestic animals (sheep, cattle) and humans, thereby facilitating the transmission of tapeworm eggs in contaminated environments. Clinical manifestations in humans include pressure organ damage, systemic toxicity and life-threatening anaphylactic reactions, with ruptured cysts and complications leading to high rates of recurrence and mortality. Based on the analyses, this paper proposes corresponding preventive strategies that emphasise comprehensive management of domestic animals in transitional grazing areas, safe handling of infected livestock organs and public health education to interrupt the ‘wildlife-livestock-human’ transmission chain.

Macrophage-mediated Immune Cell Interaction Network and its Synergistic Immune Escape Mechanism in Leishmania Protozoa Infection
type: item
description: Leishmania infection is a highly prevalent cause of parasitic disease in tropical and subtropical regions of the world, causing severe clinical symptoms such as skin ulcers and internal organ damage, posing a long-term threat to public health. Macrophages, as the main host cells of Leishmania invasion, have long been a key blind spot in the study of anti-infection immunity because of their dynamic interactions with T cells, dendritic cells (DCs), natural killer cells (NKs) and other immune cells. In this paper, we systematically analyze the synergistic escape mechanism in the macrophage-mediated immune cell network through cytokine inhibition, antigen presentation blockade, and inflammatory modulation. The article demonstrates that infected macrophages inhibit T cell activation, dendritic cell maturation, and NK cell killing through the secretion of TGF-β and IL-10. By down-regulating the expression of MHC molecules, infected macrophages form an "antigen presentation inhibition-immune cell inactivation" cascade. In addition, the study summarizes the reasons why the remodeling of the inflammatory microenvironment promotes parasite survival. This study provides new perspectives for therapeutic strategies targeting immune checkpoints.

Targeted Therapeutic Strategy for Duchenne Muscular Dystrophy Leveraging RNA Editing
type: item
description: Duchenne muscular dystrophy (DMD) is a devastation X-linked recessive genetic disorder involving progressive muscle tissue degeneration and premature death, primarily occurring in males. Current therapies such as corticosteroids and gene replacement are of limited value and suffer from the problems of enormous side effects and restrictions based on viral vectors. RNA base editing is a new-generation therapeutic strategy for genetic diseases like DMD with advantages of being reversible, less likely to lead to off-target risks than DNA editing, and direct disease-causing mRNA mutation correction. This study reviews the literature for RNA base editing as a therapy for DMD. Major RNA editing technologies, adenosine-to-inosine (A-to-I) editing by engineered ADAR enzymes , are introduced for their potential to edit out premature stop codons in the DMD mRNA to restore functional dystrophin protein expression. Key milestones include the miniaturization of editors suitable for adeno-associated virus (AAV) delivery, demonstration of efficacy in humanized DMD mouse models with dystrophin restoration and functional muscle improvement. The findings reveal the therapeutic utility of RNA base editing for DMD and propose new directions for its future clinical application.

Applications of CRISPR in the Treatment of Autoimmune Diseases
type: item
description: Autoimmune disorders are marked by the immune system’s erroneous recognition and ongoing assault on the body’s own tissues, impacting roughly 5-10% of individuals. Existing interventions, such as immunosuppressive drugs, can ease outward symptoms but cannot eliminate the root cause, while long-term use may bring about risks like heightened infection susceptibility or organ damage due to toxicity. CRISPR gene editing technology, which allows for accurate genomic modifications through Cas9 endonuclease and programmable guide RNA, has exhibited potential in treating monogenic diseases and certain tumors. However, its use in complex autoimmune conditions is still in the early investigative stage, with current approaches centered on editing genes that regulate immune cell activity and reestablishing immune tolerance. Notable research limitations include inefficient cell-type-specific delivery systems, unaddressed off-target modifications, and insufficient verification of long-term safety. This study conducts a comprehensive assessment of CRISPR-based therapeutic strategies for autoimmune diseases, encompassing the identification of disease-related genes (e.g., TLR7 in SLE and PTPN22 in RA), editing techniques (gene knockout, knock-in, and base editing), and the regulation of immune cell functions. Preclinical results show reduced production of autoantibodies, inhibited inflammatory responses, and mitigated tissue harm in models of SLE and RA. These findings offer a scientific foundation for the development of targeted, curative treatments, overcoming the drawbacks of traditional therapies. Future investigations should focus on improving editing accuracy, refining delivery systems, and performing extended safety evaluations to expedite the clinical application of personalized CRISPR-based treatments for autoimmune disorders.

Pyroptosis: A New Strategy for Oncolytic Virus Therapy of Cancer
type: item
description: In recent years, pyroptosis, as a form of proinflammatory programmed death, has been found to play a key role in the anti-tumor mechanism of OVs. This article systematically reviews the molecular mechanism of pyroptosis and tumor immune regulation, summarizes novel therapeutic strategies such as genetic engineering of OVs to enhance pyroptosis and combined with immune checkpoint inhibitors (ICIs), and analyzes their effects on tumor microenvironment (TME) immune remodeling. The results showed that OVs mainly induced pyroptosis by activating the caspase-3/GSDME pathway, releasing inflammatory factors (such as IL-18, HMGB1) and damage-associated molecular patterns (DAMPs), recruiting CD8+ T cells and natural killer (NK) cell infiltration, and thus transforming "cold tumors" into "hot tumors". OVs can be transformed to express GSDM proteins, regulate mitochondrial dysfunction, and target tumor immune components to promote the treatment of tumors through pyroptosis. This article provides a theoretical basis for the clinical transformation of OVs and suggests that pyroptosis-based combination therapy may become an important direction for future tumor im-munotherapy.

The Mechanism of Circulating Tumor Cell (CTC) Detection
type: item
description: The high lethality of cancer is mainly attributed to its metastatic ability. Circulating tumor cells (CTCs), as important mediators driving tumor metastasis, have significant research value in tumor progression and prognosis assessment. In recent years, CTC detection methods have been continuously evolving, mainly including detection based on cell surface proteins and detection based on intracellular miRNA molecular markers. Surface protein detection techniques are mature and high-throughput, but prone to missed detections when epithelial-mesenchymal transition (EMT) causes phenotypic changes; miRNA detection, on the other hand, can dynamically reflect the status of tumor cells, with high sensitivity, yet the process is complex and difficult to apply on a large scale. Currently, capturing the phenotypically heterogeneous and rare CTCs accurately remains a challenge in the field of detection. This paper systematically analyzes the principles, methods, current applications, and respective issues of the two major classes of CTC detection technologies: miRNA and surface protein detection. Furthermore, it discusses the positive role of combined detection in enhancing detection sensitivity and accuracy. Studies indicate that multi-marker combined detection can more comprehensively identify CTC heterogeneity, aiding in early tumor diagnosis, dynamic monitoring, and precise treatment. This paper provides a reference for the optimization of subsequent CTC detection technologies and in-depth research on tumor metastasis mechanisms, while pointing out current deficiencies in standardization, automation, and functional status analysis. Future research may focus on directions such as multi-omics integration and intelligent analysis.
