Two cases of cutaneous angiosarcoma of the scalp and face in the elderly are reported. Case 1 was an 89 years old man with ulcerated edematous, erythematous plagues on the scalp and right face for 2 months. Dermatological examination showed that ulcerated edematous, erythematous patches on the crown, forehead, and right face, with unclear boundaries. The involved skin was tight, shiny, and depressed under pressure. Ulcers and scabs were present on the crown (sized 2 cm×3 cm) and frontotemporal region (sized 4 cm×6 cm). Histopathology showed necrosis and atypical cells arranged in luminal pattern around lesion in the dermis. Immunohistochemistry showed CD31 (+), CD34 (+), ERG (+), HHV8 focal weak positive, P53 mutation, Ki-67 (30% +), CK (-), and CEA (-). Diagnosis: angiosarcoma. The patient and his family refused further diagnosis and treatment, and the patient passed away. Case 2 was an 81 years old female with dark erythema on the right scalp and face for 2 months. Dermatological examination revealed purple patch covered with purple papules and nodules on the right scalp and face. Skin histopathology showed slight thickening of the spinous layers, diffuse proliferation of endothelial cells in the dermis, segmentation of collagen, and atypia. Fissures and vascular lumens containing erythrocytes were also observed in the dermis. Immunohistochemistry: CD31 (+), CD34 (+), D240(+), ERG(+), Ki-67(≈35%+), S100(-), HMB45(-), and CK(-). Diagnosis: angiosarcoma of the scalp and face. The patient was transferred to the oncology department for radiotherapy and chemotherapy, and passed away during follow-up.

Objective: This study aimed to investigate the factors influencing nurses’ ability to respond to public health emergencies and understand the relationship between nurses’ ability to respond to emergencies and workplace resilience. Methods: A cross-sectional study of 361 nurses from military hospitals was conducted from January 18 to September 6, 2022, using an online survey. The Infectious Diseases Emergency Response Capacity (IDERC) questionnaire and the Workplace Resilience Scale (WRS) were utilized, and sociodemographic information was also collected. Data were analyzed using descriptive statistics and frequency analysis. Differences between groups were identified by one-way analysis of variance, and linear regression was used to analyze the main factors influencing the infectious emergency response capacity. Results: The average infectious emergency response capacity score on the IDERC questionnaire and workplace resilience, measured by WRS, were 4.01 (SD = 0.76) and 3.85 (SD = 0.71), respectively, on a scale of 1–5, indicating high performance. Factors such as degree of education, nurses’ service years and experience in epidemic prevention participation were found to be the main influencing factors of the score of IDERC. The level of workplace resilience showed a positive correlation with the capacity to respond to infectious disease, the score of WRS and the service year accounted for 63.6% of the variance in emergency response capabilities. Conclusion: The results indicate an urgent need to strengthen the training of nurses with lower degree of education, shorter service years, no prior work, or no experience of epidemic prevention participation, and hospitals should also prioritize improving nurses’ workplace resilience through targeted interventions, enhancing their abilities in infectious disease prevention, preparation, first aid, and subsequent critical patient care.

Abstract Background The objective was to investigate the efficacy of different doses of levothyroxine therapy among pregnant women exhibiting high-normal thyroid stimulating hormone levels and positive thyroid peroxidase antibodies throughout the first half of pregnancy. Methods Pregnant women exhibiting high-normal thyroid stimulating hormone levels and thyroid peroxidase antibodies positivity throughout the initial half of pregnancy were selected from January 2021 to September 2023. Based on the different doses of levothyroxine, the pregnant women were categorized into the nonintervention group (G0, 122 women), 25 µg levothyroxine intervention group (G25, 69 women), and 50 µg levothyroxine intervention group (G50, 58 women). Serum parameters, gastrointestinal symptoms, small intestinal bacterial overgrowth (SIBO), maternal and neonatal outcomes were compared after the intervention among the three groups. Results After the intervention, in the G25 and G50 groups, the thyroid stimulating hormone, triglyceride and low-density lipoprotein levels were notably less in contrast to those in the G0 group (P

Bartonella spp. are globally distributed gram-negative facultative intracellular bacteria that infect a wide range of hosts. Rodents are natural reservoirs of many Bartonella species, some of which are also pathogenic to humans. The rapid development of transportation and tourism has highlighted the risk of Bartonella transmission to humans. Thus, it is essential to maintain surveillance of Bartonella spp. infections in rodents. In China, Bartonella spp. infections have been monitored in various areas; however, these have not included the Hulunbuir border regions. In the present study, we monitored the prevalence and genetics of rodent-associated Bartonella spp. in the Hulunbuir border regions. Eleven rodent species were captured at five ports. Eight species were confirmed as Bartonella-positive using quantitative PCR assay, with an overall positivity rate of 20.05 %. Lasiopodomys brandtii was the predominant rodent species captured for Bartonella detection. Sequencing and phylogenetic analysis (using the maximum likelihood method) revealed the presence of three Bartonella species in these rodents, including two pathogenic to humans, namely, Bartonella alsatica and Bartonella grahamii. B. grahamii was the predominant Bartonella species identified in the rodents. Taken together, these results highlight the prevalence and genetic diversity of Bartonella spp. in rodents in the Hulunbuir border regions, indicating the need for risk assessment of human spillover.

GeSn materials with Sn contents ranging between 0% and 11% have been successfully grown by using Ge2H6 and SnCl4 in a hot-wall UHV-CVD system at low reaction pressures of 0.2–0.4 Torr. Both fully strained and partially relaxed materials have been produced. It was found that the materials were of high crystallinity as evidenced by few threading dislocations from cross-sectional TEM. Photoluminescence studies have shown that the PL spectra shift to longer wavelengths, and the PL intensity increases exponentially as the Sn contents increase. The photoemission cutoff for a 9.5% Sn sample is beyond 2600 nm, and low temperature PL measurements have confirmed that this sample is already in the direct gap material regime. Prototype photoconductor devices were fabricated with a partially strained 5% Sn sample, showing much smaller dark currents and similar spectral coverage as compared to a fully strained 7.8% Sn device reported in the literature. The reported technical route has provided a new path toward high quality, low cost GeSn epitaxy, and will contribute to the development of group IV optoelectronics.

Calcium sulfate, generally in the form of gypsum or bassanite, is a significant component in oil well cement. The impact of gypsum/bassanite on the fluid loss of cement slurry was thoroughly examined with varied concentrations of a 2-Acrylamido-2-methylpropane sulfonic acid based fluid loss additive (AMPS-FLA). It was found that bassanite in cement was more conducive to decreasing the fluid loss than gypsum. The results showed that the dissolution rate of bassanite in cement slurry was faster than that of gypsum, generating more Ca2+ and resulting in a reduction in the adsorption capacity of the AMPS-FLA on cement particle surfaces. The adsorption mechanism of FLAs cannot explain the result. This study discovered that the equilibrium concentration of the AMPS-FLA in the pore solution had a good functional relationship with the fluid loss, which was not impacted by cement components. Increasing the equilibrium concentration helped reduce the fluid loss.

ABSTRACT: Avian leukemia virus subgroup J (ALV-J) and chicken infectious anemia virus (CIAV) can be vertically transmitted; however, the pathogenicity of vertically transmitted coinfection with these 2 pathogens has not been studied. In this study, we created a model of chick morbidity in which chicks carried either ALV-J, CIAV, or both viruses via embryo inoculation. Thereafter, we analyzed the effects of vertically transmitted coinfection with CIAV and ALV-J on the pathogenicity of ALV-J and performed a purification assay based on hatching, mortality viremia positivity, and detection of fecal ALV-p27 antigen rates, and body weight. The hatching rate of the ALV-J+CIAV group was 68.57%, lower than those of the single infection and control groups. The survival curve showed that the mortality rates of the CIAV and ALV-J coinfection groups were higher than those of the single infection and control groups. Body weight statistics showed that coinfection aggravated the 7-d growth inhibition effect. The results of ALV-p27 antigen detection in cell culture supernatants showed that the positivity rates of the ALV-J and ALV-J+CIAV groups were 100% at all ages and 0% in the control group. The results of ALV-p27 antigen detection by anal swabs showed that the positivity rates of the ALV-J group were 92.86, 90.90, 88.89, and 93.33% at all ages, and that the ALV-J p27 positivity detection rate of anal swabs was lower than that of plasma virus isolation. The immune organ index of the ALV-J+CIAV group was significantly or very significantly lower than those of the single infection and control groups. The immune organ viral load showed that coinfection with CIAV and ALV-J promoted the proliferation of ALV-J and CIAV in immune organs. Coinfection with ALV-J and CIAV reduced chicken embryo hatchability and increased chick mortality and growth inhibition relative to their respective single infections. Additionally, coinfection with ALV-J + CIAV was even more detrimental in inducing immune organ atrophy (e.g., the thymus, spleen, and bursa), and promoted individual virus replication during coinfection.

ABSTRACT: Marek's disease virus (MDV) is a significant tumorigenic virus that causes severe immunosuppression in chickens. Lentinan (LNT) is an immunomodulator containing β-glucans and is widely used in areas such as antiviral, anticancer, and immune regulation. To investigate the immunomodulatory effects of LNT on specific pathogen-free (SPF) chicks and its potential to inhibit MDV infection, we conducted an MDV challenge experiment and observed the immune-enhancing effect of LNT on SPF chicks. The results showed that LNT promoted the growth and development of SPF chicks and induced the upregulation of cytokines such as Mx protein, interferon-γ (INF-γ), tumor necrosis factor-α (TNF-α), and interleukin-2 (IL-2). The specific gravity of CD4+ T-lymphocytes and CD8+ T-lymphocytes and their ratios were also significantly upregulated. Prophylactic use of LNT inhibited MDV replication in lymphocytes, liver, and spleen. It also alleviated MDV-induced weight loss and hepatosplenomegaly in SPF chicks. The present study confirms that LNT can enhance the levels of innate and cellular immunity in SPF chicks and contributes to the inhibition of MDV replication in vivo and mitigation of immune organ damage in chicks due to MDV infection. This provides an adjunctive measure for better control of MDV infection.

Abstract Background Thoracoscopic surgical techniques continue to advance, yet the intensity of postoperative pain remains significant, impeding swift patient recovery. This study aimed to evaluate the differences in postoperative pain and recuperation between patients receiving intrathecal morphine paired with low-dose bupivacaine and those administered general anesthesia exclusively. Methods This randomized controlled trial enrolled 100 patients, who were allocated into three groups: Group M (5 μg/kg morphine intrathecal injection), Group B (5 μg/kg morphine combined with bupivacaine 3 mg intrathecal injection) and Group C (intrathecal sham injection). The primary outcome was the assessment of pain relief using the Numeric Rating Scale (NRS). Additionally, intraoperative remifentanil consumption was quantified at the end of the surgery, and postoperative opioid use was determined by the number of patient-controlled analgesia (PCIA) compressions at 48 h post-surgery. Both the efficacy of the treatments and any complications were meticulously recorded. Results Postoperative NRS scores for both rest and exercise at 6, 12, 24, and 48 h were significantly lower in groups M and B than in group C (P0.05). There was no significant difference in intraoperative propofol dosage across all three groups (P>0.05). Postoperative dosages of both sufentanil and Nonsteroidal anti‐inflammatory drugs (NSAIDs) were significantly less in groups M and B compared to group C (P

Abstract Yes-associated protein (YAP) is a pivotal regulator in cellular proliferation, survival, differentiation, and migration, with significant roles in embryonic development, tissue repair, and tumorigenesis. At the maternal–fetal interface, emerging evidence underscores the importance of precisely regulated YAP activity in ensuring successful pregnancy initiation and progression. However, despite the established association between YAP dysregulation and adverse pregnancy outcomes, insights into the impact of aberrant YAP levels in fetal-derived, particularly trophoblast cells, and the ensuing dysfunction at the maternal–fetal interface remain limited. This review comprehensively examines YAP expression and its regulatory mechanisms in trophoblast cells throughout pregnancy. We emphasize its integral role in placental development and maternal–fetal interactions and delve into the correlations between YAP dysregulation and pregnancy complications. A nuanced understanding of YAP's functions during pregnancy could illuminate intricate molecular mechanisms and pave the way for innovative prevention and treatment strategies for pregnancy complications.

Background Although several studies have addressed plasma proteomics in heart failure with preserved ejection fraction, limited data are available on the prognostic value of urinary proteomics. The objective of our study was to identify urinary proteins/peptides associated with death and heart failure admission in patients with heart failure with preserved ejection fraction. Methods and Results The study population included participants enrolled in TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist Trial). The relationship between urine protein levels and the risk of death or heart failure admission was assessed using Cox regression, in both nonadjusted analyses and adjusting for urine creatinine levels, and the MAGGIC (Meta‐Analysis Global Group in Chronic Heart Failure) score. A total of 426 (12.4%) TOPCAT participants had urinary protein data and were included. There were 40 urinary proteins/peptides significantly associated with death or heart failure admission in nonadjusted analyses, 21 of which were also significant adjusted analyses. Top proteins in the adjusted analysis included ANGPTL2 (angiopoietin‐like protein 2) (hazard ratio [HR], 0.5731 [95% CI, 0.47–0.7]; P=3.13E‐05), AMY2A (α amylase 2A) (HR, 0.5496 [95% CI, 0.44–0.69]; P=0.0001), and DNASE1 (deoxyribonuclease‐1) (HR, 0.5704 [95% CI, 0.46–0.71]; P=0.0002). Higher urinary levels of proteins involved in fibrosis (collagen VI α‐1, collagen XV α‐1), metabolism (pancreatic α‐amylase 2A/B, mannosidase α class 1A member 1), and inflammation (heat shock protein family D member 1, inducible T cell costimulatory ligand) were associated with a lower risk of death or heart failure admission. Conclusions Our study identifies several novel associations between urinary proteins/peptides and outcomes in heart failure with preserved ejection fraction. Many of these associations are independent of clinical risk scores and may aid in risk stratification in this patient population.

BackgroundHospital resilience is essential in responding to disasters, but current research focuses mainly on frameworks and models rather than the protection of resilience and analysis of risk factors during public health emergencies. This study aims to examine the development of resilience in Chinese frontline hospitals during the initial COVID-19 outbreak in 2020, providing insights for future disaster response efforts.ObjectivesWe conducted interviews with 26 hospital staff members who were involved in the initial response to the COVID-19 outbreak in China. We used a semi-structured interview approach and employed purposive sampling and snowball sampling techniques. The interview outline was guided by the ‘Action Framework’ proposed by the World Health Organization (WHO) for responding to infectious disease emergencies. This framework includes dimensions such as command, surveillance, risk communication, medical response, and public health response. We analyzed the collected data using Colaizzi’s seven-step data analysis method and the template analysis method.ResultsWHO’s ‘action framework’ effectively highlights the factors that contribute to hospital resilience. While medical response, including the availability of materials and facilities, the use of information technology, and the capacity for infectious disease diagnosis and treatment, remains crucial, other important aspects include awareness and beliefs about infections, treatment experience, interdisciplinary collaboration, and more. Additionally, it is essential to establish an intelligent command system, foster trusting partnerships between teams, improve monitoring capabilities for infectious disease agents, enhance risk communication through information synchronization and transparency, strengthen infection control planning, and improve environmental disinfection capabilities for effective public health emergency response. These contradictions significantly impact the enhancement of hospital resilience in dealing with major infectious disease outbreaks.ConclusionIn responding to sudden major infectious diseases, hospitals play a vital role within the healthcare system. Enhancing hospital resilience involves more than just improving treatment capabilities. It also requires effective command coordination at the hospital level, infection control planning, and the deployment of intelligent equipment. Additionally, planning for effective communication and coordination between hospitals, communities, and the national healthcare system can further enhance hospital resilience.

Abstract Asterias amurensis has attracted widespread concern because of its population outbreaks, which has impacted fisheries and aquaculture, as well as disrupting local ecosystems. A high-quality reference genome is necessary to better investigate mechanisms of outbreak and adaptive changes. Combining PacBio HiFi and Hi-C sequencing data, we generated a chromosome-level A. amurensis genome with a size of 491.53 Mb. The contig N50 and scaffold N50 were 8.05 and 23.75 Mb, respectively. The result of BUSCO analysis revealed a completeness score of 98.85%. A total of 16,531 protein-coding genes were predicted in the genome, of which 94.63% were functionally annotated. The high-quality genome assembly resulting from this study will provide a valuable genetic resource for future research on the mechanism of population outbreaks and invasion ecology.

Abstract Background Caveolin-1 (Cav-1) is a pivotal protein in the plasma membrane. Studies on homozygous Cav-1 deficient mice revealed that Cav-1 is essential for endothelial function and angiogenesis in the retina. However, whether a reduction in Cav-1 content hampers the neurovascular unit (NVU) in the retina is unclear. Thus, this study examines the NVU in the retinas of heterozygous Cav-1 deficient (Cav-1+/−) mice and analyzes possible underlying mechanisms. Methods The vascular, glial and neuronal components in the retina were evaluated using retinal morphometry, whole mount retinal immunofluorescence staining, histological analysis and optical coherence tomography. In addition, immunoblotting and immunofluorescence staining, subcellular fractionation, biotin labeling of cell surface proteins, and proximity ligation assay were employed to detect expression and localization of proteins in the retina or endothelial cells (ECs) upon knockdown of Cav-1 with Cav-1 siRNA. Results Cav-1+/− retinas showed a significant reduction in pericyte coverage along with an increase in acellular capillaries compared to controls at 8 months of age, but not at 1 month. A significant loss and obvious morphological abnormalities of smooth muscle cells were observed in 8-month-old Cav-1+/− retinal arterioles. Macroglial and microglial cells were activated in the Cav-1+/− retinas. A transient significant delay in retinal angiogenesis was detected in Cav-1+/− retinas at p5, which was however no longer detectable at p10. The Cav-1+/− retinas displayed increased vascular permeability and a notable reduction in VEGFR2 content at 8 months. In vitro, siRNA-mediated knockdown experiments in ECs revealed that the loss of Cav-1 in ECs resulted in decreased levels of VEGFR2, VE-Cadherin and their interaction at the plasma membrane as well. Conclusion Our results indicate that a sufficient Cav-1 level over 50% of its normal abundance is vital for the proper localization of VEGFR2 and VE-cadherin, likely in a complex, at the plasma membrane, which is essential for the maintenance of normal NVU in the retina.

Abstract Stretchable and curved electronic devices are a promising technology trend due to their remarkable advantages. Many approaches have been developed to manufacture stretchable and curved electronics. Here, to allow such electronics to better serve practical applications, ranging from wearable devices to soft robotics, we propose a novel vertical serpentine conductor (VSC) with superior electrical stability to interconnect functional devices through a silicon-based microfabrication process. Conformal vacuum transfer printing (CVTP) technology was developed to transfer the networked platform onto complex curved surfaces to demonstrate feasibility. The mechanical and electrical performance were investigated numerically and experimentally. The VSC interconnected network provides a new approach for stretchable and curved electronics with high stretchability and reliability.

【Objective】Avian leukosis virus subgroup J (ALV-J) and reticuloendotheliosis virus (REV) can be transmitted vertically through chicken embryos, and there have been reports of chicken embryos that are co-infected with the two viruses, however, the pathogenicity of co-infection between the two through chicken embryos has not been studied. An experimental animal model of vertical transmission of ALV-J and REV was established to study the pathogenicity of vertical transmission of ALV-J and REV and its effect on the purification test of avian leukaemia, with a view to providing a reference for the promotion of the synergistic purification of multiple pathogens.【Method】An infection model for chicks carrying ALV-J, REV and co-infected with the two viruses was constructed respectively by means of chicken embryo inoculation, and the pathogenicity of co-infection of REV and ALV-J in vertical transmission was analyzed by the indexes of hatching rate, mortality rate, body weight, fetal-feces ALV-p27 antigen detection rate, and viraemia positive rate.【Result】The hatching rate of the chicken embryos in the co-infection group of ALV-J+REV was 65.71%, which was lower than that in the mono-infection group and CK; the mortality rate in the co-infection group was higher than that in the mono-infection group and CK. The average weights of chicken in the CK, ALV-J group, REV group and ALV-J+REV group were 59.25, 50.83, 49.67, 43.78 g, indicating that co-infection increased the inhibition of growth. The results of ALV plasma virus isolation showed that the positive rates of ALV-J group and ALV-J+REV group were 100% at each day age, while the rate of CK was 0%. The results of anal swabs collected for the detection of ALV-27 antigen showed that the positive rates of ALV-J + REV group were 91.30%, 93.75%, 90.90% and 100% at day age (s) of 1, 3, 7 and 14, respectively, and the positive detection rate of ALV-J p27 in anal swabs was lower than that of plasma virus isolation. Comparison of the results of the immune organ development showed that, both ALV-J mono-infection and REV mono-infection could lead to the atrophy of chicken immune organs, while co-infection of them aggravated the degree of atrophy. The viral load of immune organs showed that the co-infection of REV and ALV-J promoted the proliferation of ALV-J in immune organs, while ALV-J also promoted the proliferation of REV in immune organs.【Conclusion】Co-infection of ALV-J and REV reduced embryo hatching rate, increased chick mortality and enhanced growth inhibition compared with mono-infection of ALV-J and REV, and the effect was more pronounced on inducing atrophy of immune organs such as the thymus, spleen and bursa, and both promoted mutual replication during co-infection.

Abstract The rapidly evolving landscape of biomarkers for colorectal cancer (CRC) necessitates an integrative, updated repository. In response, we constructed the Colorectal Cancer Biomarker Database (CBD), which collected and displayed the curated biomedicine information for 870 CRC biomarkers in the previous study. Building on CBD, we have now developed CBD2, which includes information on 1569 newly reported biomarkers derived from different biological sources (DNA, RNA, protein, and others) and clinical applications (diagnosis, treatment, and prognosis). CBD2 also incorporates information on nonbiomarkers that have been identified as unsuitable for use as biomarkers in CRC. A key new feature of CBD2 is its network analysis function, by which users can investigate the visible and topological network between biomarkers and identify their relevant pathways. CBD2 also allows users to query a series of chemicals, drug combinations, or multiple targets, to enable multidrug, multitarget, multipathway analyses, toward facilitating the design of polypharmacological treatments for CRC. CBD2 is freely available at http://www.eyeseeworld.com/cbd.

Breast cancer continues to have a high incidence rate among female malignancies. Despite significant advancements in treatment modalities, the heterogeneous nature of breast cancer and its resistance to various therapeutic approaches pose considerable challenges. Antibody-drug conjugates (ADCs) effectively merge the specificity of antibodies with the cytotoxicity of chemotherapeutic agents, offering a novel strategy for precision treatment of breast cancer. Notably, trastuzumab emtansine (T-DM1) has provided a new therapeutic option for HER2-positive breast cancer patients globally, especially those resistant to conventional treatments. The development of trastuzumab deruxtecan (T-DXd) and sacituzumab govitecan (SG) has further broadened the applicability of ADCs in breast cancer therapy, presenting new hopes for patients with low HER2 expression and triple-negative breast cancer. However, the application of ADCs presents certain challenges. For instance, their treatment may lead to adverse reactions such as interstitial lung disease, thrombocytopenia, and diarrhea. Moreover, prolonged treatment could result in ADCs resistance, complicating the therapeutic process. Economically, the high costs of ADCs might hinder their accessibility in low-income regions. This article reviews the structure, mechanism of action, and clinical trials of commercially available ADCs for breast cancer treatment, with a focus on the clinical trials of the three drugs, aiming to provide insights for clinical applications and future research.

ABSTRACT The avian influenza virus (AIV), a member of the type A influenza virus group, is harbored by avian hosts. The highly pathogenic H5 subtype of AIV has inflicted significant financial damage on the poultry industry and also presents a possible pandemic hazard to the worldwide human population. There is an urgent need for a detection method that is both rapid and accurate in identifying H5-AIV. In this study, two assays based on reverse transcription recombinase-aided amplification technology (RT-RAA) have been developed to detect H5-AIV, namely, real-time fluorescence and reverse transcription recombinase-aided amplification (RF-RT-RAA) and reverse transcription recombinase-aided amplification combined lateral flow dipstick (RT-RAA-LFD). The completion of the two methods can be achieved in 30 min, and there was no cross-reaction with the nucleic acid of other avian pathogens. The results indicated that the lowest detectable limit of RF-RT-RAA and RT-RAA-LFD for H5-AIV detection was 1 copy/μL, which was 100 times higher than that of RT-PCR (102 copies/μL). A total of 376 samples, consisting of 350 clinical and 26 experimental samples, underwent testing utilizing virus isolation, RF-RT-RAA and RT-RAA-LFD methods, respectively. The results demonstrated a high degree of consistency between those assays. In summary, both the RF-RT-RAA and RT-RAA-LFD methods demonstrated excellent specificity and sensitivity, making them ideal for use in both laboratory and field settings. IMPORTANCE Avian influenza virus (AIV) subtype H5 is a highly contagious zoonotic disease and a serious threat to the farming industry and public health. Traditional detection methods, including virus isolation and real-time PCR, require tertiary biological laboratories and are time-consuming and complex to perform, making it difficult to rapidly diagnose H5 subtype avian influenza viruses. In this study, we successfully developed two methods, namely, RF-RT-RAA and RT-RAA-LFD, for rapid detection of H5-AIV. The assays are characterized by their high specificity, sensitivity, and user-friendliness. Moreover, the results of the reaction can be visually assessed, which are suitable for both laboratory testing and grassroots farm screening for H5-AIV.
