Objective To establish a fluorescent recombinase-aided amplification (RAA) assay for detection of Strongyloides stercoralis nucleic acid and to preliminarily evaluate its performance. Methods Six sets of specific primers targeting S. stercoralis 18S ribosomal RNA (18S rRNA) gene and one fluorescent probe were designed and synthesized. The optimal primer-probe set was determined through systematic screening and optimization to establish the fluorescent RAA assay. The assay was evaluated using S. stercoralis genomic DNA at concentrations of 100, 10, and 1 pg/μL, and 100, 10, and 1 fg/μL, as well as recombinant pUC57 plasmids containing the target gene fragments at 1 × 105, 1 × 104, 1 × 103, 1 × 102, 1 × 101, 1 × 100 copies/reaction, to determine the analytical sensitivity. Genomic DNA from Ascaris lumbricoides, Ancylostoma duodenale, Enterobius vermicularis, Angiostrongylus cantonensis, Trichinella spiralis, Clonorchis sinensis, Schistosoma japonicum, and Taenia saginata was used to assess assay specificity. A total of 25 stool samples from patients suspected of S. stercoralis infection were tested by the modified Baermann funnel technique, PCR, and the established fluorescent RAA assay. The sensitivity, specificity, concordance rate and their 95% confidence intervals (CI) of these three techniques were estimated, and agreement between methods was evaluated using the Kappa coefficient. Results Exo-4 was identified as the optimal primer set screened from the six primer sets, and the best amplification performance was achieved when the final concentrations of the forward and reverse primers were 0.44 μmol/L and a probe concentration was 0.20 μmol/L. The limit of detection of the fluorescent RAA assay was 100 fg/μL for genomic DNA of S. stercoralis and 1 × 100 copies/reaction for recombinant plasmids. Specific fluorescence signals were detected within 5 min, with no cross-reactivity observed with A. lumbricoides, A. duodenale, E. vermicularis, A. cantonensis, T. spiralis, C. sinensis, S. japonicum, or T. saginata. Among the 25 clinical stool samples from patients suspected of S. stercoralis infections, the modified Baermann funnel technique and fluorescent RAA assay detected 19 positives and 6 negatives, whereas PCR detected 18 positives and 7 negatives. The fluorescent RAA assay showed a sensitivity of 100.00% [95% CI: (82.35%, 100.00%)], specificity of 100.00% [95% CI: (54.07%, 100.00%)], concordance rate of 100.00% [95% CI: (86.28%, 100.00%)], and a Kappa coefficient of 1.00 [95% CI: (1.00, 1.00)] (P < 0.001) relative to the modified Baermann funnel technique, and a sensitivity of 100.00% [95% CI: (81.47%, 100.00%)], specificity of 85.71% [95% CI: (42.13%, 99.64%)], concordance rate of 96.00% [95% CI: (79.65%, 99.90%)], and a Kappa coefficient of 0.90 [95% CI: (0.70, 1.00)] (P < 0.001). Positive amplification products emitted green fluorescence under a portable blue-light device, enabling visual interpretation of results. Conclusions The fluorescent RAA assay established in this study is rapid, highly sensitive, and highly specific. It enables detection of S. stercoralis nucleic acid under isothermal conditions and allows visual interpretation of results, providing a novel tool for rapid clinical diagnosis and field screening of S. stercoralis infections.

ObjectiveTo analyze the clinical manifestations, diagnostic approaches, treatment strategies, and prognostic outcomes of uterine arteriovenous fistula (UAVF). MethodsWe retrospectively analyzed 6 patients with confirmed UAVF admitted to the Department of Gynecology, the Eighth Affiliated Hospital of Sun Yat-sen University, between January 2010 and December 2023. We summarized the clinical data of the cohort, including age, gravidity, chief complaints, treatment regimens, and postoperative follow-up outcomes, and explored the clinical efficacy and safety of ultrasound-guided microwave ablation for UAVF in conjunction with a literature review. ResultsThe patients were aged 26-44 years, with a mean age of (34.33±6.12) years and a median age of 33.5 years. All patients were initially screened via color Doppler ultrasound and definitively diagnosed by imaging modalities including uterine arteriography, computed tomography, and magnetic resonance imaging. The median gravidity was 4(4,6), with 5 patients having a history of ≥2 pregnancies. Five patients had a history of intrauterine instrumentation, among whom 4 had undergone ≥2 procedures. Regarding clinical presentations, 3 patients presented with abnormal vaginal bleeding (2 with massive hemorrhage), 2 were asymptomatic with abnormalities detected only on imaging, and 1 reported lower abdominal pain. In terms of management, 1 patient with recurrence after uterine artery embolization (UAE) underwent ultrasound-guided microwave ablation; 1 received UAE alone; 2 patients with concomitant retained products of conception underwent hysteroscopic mechanical morcellation (1 developed massive hemorrhage 10 hours postoperatively, which was successfully controlled with uterine balloon tamponade); 1 underwent focal lesion resection; and 1 underwent total hysterectomy. All 6 patients achieved favorable therapeutic outcomes. ConclusionAbnormal vaginal bleeding is the most typical clinical manifestation of UAVF, and digital subtraction angiography of the uterine arteries is recognized as the gold standard for definitive diagnosis. Emergency UAE is indicated for patients presenting with acute massive hemorrhage and hemodynamic instability. For patients with failed UAE or post-UAE recurrence who desire uterine and fertility preservation, ultrasound-guided microwave ablation represents a safe, effective, and novel minimally invasive therapeutic option.

ObjectiveTo investigate the effects of paeoniflorin (PF) on neuroinflammation and cognitive impairment in the rat model of Alzheimer's disease (AD) and to clarify whether its mechanism is associated with regulation of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. MethodsGlycosides related to AD-associated neuroinflammation were screened through bibliometric analysis, and the potential targets of PF were predicted through network pharmacology and molecular docking. A rat model of AD was established by intraperitoneal injection of D-galactose (100 mg·kg-1·d-1). Rats were assigned into a control group, a model group, a PF (200 mg·kg-1) group, and a donepezil (0.5 mg·kg-1·d-1) group, and drugs were administered by gavage for 21 days. The learning and memory abilities were evaluated by the Morris water maze (MWM). Hematoxylin-eosin (HE) staining and Nissl staining were performed to observe hippocampal neuronal morphology. The mRNA levels of inflammatory factors were determined by Real-time quantitative polymerase chain reaction (Real-time PCR), and the protein levels of molecules in the JAK2/STAT3 signaling pathway were determined by Western blot. ResultsCompared with the control group, the model group showed prolonged escape latency and decreased platform crossings and time spent in the target quadrant (P<0.05, P<0.01), accompanied by increased expression of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α), as well as elevated ratios of phosphorylated (p)-JAK2/JAK2 and p-STAT3/STAT3 (P<0.01). Compared with the model group, the PF group and donepezil group exhibited shortened escape latency and increased platform crossings and time spent in the target quadrant (P<0.05, P<0.01), decreased expression levels of IL-1β and TNF-α, upregulated mRNA levels of interleukin-4 (IL-4) and interleukin-10 (IL-10), and reduced ratios of p-JAK2/JAK2 and p-STAT3/STAT3 (P<0.05, P<0.01). ConclusionPaeoniflorin can alleviate cognitive impairment and neuroinflammation in the rat model of AD by inhibiting the JAK2/STAT3 signaling pathway.

Protein liquid-liquid phase separation (LLPS), a pivotal phenomenon intricately linked to cellular processes, is regulated by various other proteins. However, there is still a lack of high-throughput methods for screening protein regulators of LLPS in target proteins. Here, we developed a CRISPR/Cas9-based screening method to identify protein phase separation regulators by integrating bimolecular fluorescence complementation (BiFC) and fluorescence-activated cell sorting (FACS). Using this newly developed method, we screened the RNA-binding proteins that regulate PABPN1 phase separation and identified the tumor suppressor QKI as a promoter of PABPN1 phase separation. Furthermore, QKI exhibits decreased expression levels and diminished nuclear localization in colorectal cancer cells, resulting in reduced PABPN1 phase separation, which, in turn, promotes alternative polyadenylation (APA), cell proliferation, and migration in colorectal cancer.

Objective To explore the relationship between C-reactive protein/albumin ratio(CAR)and the disease severity in patients with severe pneumonia,and its predictive value for 28-day mortality risk.Methods A retrospective analysis was conducted on 152 patients with severe pneumonia admitted to Fuyang People's Hospital from January 2020 to January 2022.They were divided into non-critical illness group(n=51),critical illness group(n=63),and extremely critical illness group(n=38)based on the disease severity.The clinical data such as age and gender of patients was collected,and Pearson correlation analysis was used to explore the correlation between CAR and the severity of illness[determined by Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)score].Multivariate logistic regression was employed to identify independent influencing factors of the severity of illness.According to the survival status of patients after 28 days of treatment,they were divided into survival group(n=107)and death group(n=45).CAR was categorized into quintiles(Q1-Q5),and multivariate logistic regression analysis was conducted to explore the correlation between CAR and 28-day mortality risk in severe pneumonia patients.A restricted cubic spline(RCS)model was used to analyze the dose-response relationship between CAR and mortality risk.The predictive value of CAR and related indicators for patient mortality risk was evaluated using the receiver operating characteristic curve(ROC).Results CAR was significantly positively correlated with the severity of the disease(APACHE Ⅱ score)(r=0.716,P<0.05).Neutrophil/lymphocyte ratio(NLR),blood lactate(Lac),and high CAR were independent risk factors for the disease severity in patients with severe pneumonia(P<0.05).After adjusting for confounding factors,the mortality risk increased with the increase of CAR(P<0.05).Subgroup analysis of the screened confounding factors revealed that the correlation between CAR and 28-day mortality risk in severe pneumonia patients remained stable across different APACHE Ⅱ scores,GCS scores,SOFA scores,white blood cell counts(WBC),neutrophils(NEU),red cell volume distribution width(RDW),procalcitonin(PCT),and Lac,with interactions observed between NLR and Lac subgroups(P<0.05).The RCS model indicated that there was no non-linear dose-response relationship between CAR and 28-day mortality risk in patients with severe pneumonia of different genders.ROC curve analysis showed that CAR,Lac,and NLR had good predictive value for 28-day mortality in severe pneumonia patients,with the combined predictive efficacy being significantly higher than that of individual indicators.Conclusion There is a close relationship between CAR and the progression and prognosis of severe pneumonia,making it a new approach to assessing the severity of illness and predicting mortality risk in patients.
