Aim To establish a simple and practical method for visualizing neurovascular coupling in the mouse barrel cortex in vivo.Methods Male C57BL/6J mice received stereotaxic in-jections of pAAV-hSyn-jGCaMP7s-WPRE into the barrel cortex to monitor neuronal activity.Three weeks post-injection,a crani-al window was implanted,and TRITC-Dextran 155 ku was ad-ministered intravenously to visualize the vasculature and blood flow dynamics.A custom-built whisker stimulator was used to e-voke controlled neuronal excitation.Two-photon microscopy was employed to monitor neuronal and vascular responses to whisker stimulation in real-time.Results Neuronal calcium signals and plasma signals were clearly observed using two-photon microsco-py.Whisker stimulation led to a significant increase in neuronal calcium signals in the barrel cortex,indicating effective neuronal activation.This neuronal excitation was accompanied by a syn-chronous increase in blood vessel diameter,blood flow velocity and overall blood flow.Conclusions This study successfully establishes a three-dimensional visualization framework(spatial,temporal,and functional)for in vivo visualization of neurovascu-lar coupling in the mouse barrel cortex,which provides a useful tool for investigating the pathophysiological mechanisms of neuro-vascular dysfunction and evaluating the efficacy of potential ther-apies.

Objective To explore the differences in muscle synergies of healthy individuals,intact limbs and residual limbs of above-knee amputees under different gaits,provide references for electromyographic control of the prosthetics.Methods Surface electromyography(sEMG)signals of 7 muscles(4 thigh muscles,3 calf muscles)were collected from 7 healthy individuals and 3 lower-limb amputees during level walking,ascending/descending slopes,and ascending/descending stairs.Muscle synergy weights(W)and temporal activation coefficients(H)were extracted using concatenated non-negative matrix factorization(CNMF).The W matrices were compared using the coefficient of determination R2,and the activation coefficients were analyzed using statistical parametric mapping(SPM).Furthermore,peak activation and activation integral were used for hierarchical clustering analysis.Results The comparison of W matrices indicated a similar set of muscle synergies between the healthy group and the intact limb of amputees,whereas the residual limb showed greater variability in synergies.The analysis of H showed statistically significant differences in muscle activation throughout the gait cycle for all amputees.Clustering of time-domain features revealed that amputees exhibited higher activation integral and peak values in their intact limb during ascending slopes.Conclusions This study provides an in-depth investigation of the neuromuscular compensation strategies in lower-limb amputees under different gaits,offering theoretical insights for gait rehabilitation and assisting in the development of EMG-controlled prosthetics.

AIM To investigate the effects of Xuesaitong Capsules(Panax notoginseng saponins)on ischemia/reperfusion injury in a mouse model of skin frostbite.METHODS The mice were randomly divided into the control group,the model group,the dexamethasone group(1 mg/kg),and the low-dose,medium-dose,and high-dose Xuesaitong Capsules groups(0.036,0.072,and 0.144 g/kg),with eight mice in each group.A frostbite model was established using a dry ice-cooled ceramic(ferrite)magnet.On the 2nd day after modeling,each group started its corresponding dosing by gavage for 14 consecutive days.The wound healing,histopathological changes,and serum levels of high-sensitivity C-reactive protein(hs-CRP),thromboxane B2(TXB2),6-keto-prostaglandin F1α(6-K-PGF1α),nitric oxide(NO)and endothelin(ET)were assessed using ELISA.The superoxide dismutase(SOD)activity and malondialdehyde(MDA)levels in skin tissues were measured biochemically.The protein expressions of tumor necrosis factor(TNF)-α,interleukin(IL)-1β,IL-6,Toll-like receptor(TLR)4 and phosphorylated nuclear factor-KB p65(p-NF-κB p65)in skin tissues were determined by Western blot.Additionally,LncRNA H19 mRNA expression in skin tissues was evaluated using RT-qPCR.RESULTS After the final administration,compared with the control group,the model group exhibited partial scab detachment,wound healing,and larger wound areas;hyperkeratosis with incomplete keratinization,detachment of the dermis and subcutaneous tissue,partial loss of appendages,subcutaneous edema,and dilated,congested,and hemorrhagic stromal vessels with extensive lymphocyte infiltration revealed by the histopathological examination;elevated serum levels of hs-CRP,TXB2,and ET(P＜0.05,P＜0.01);decreased 6-K-PGF1α and NO levels(P＜0.05,P＜0.01);reduced SOD activity in skin tissues(P＜0.01);increased MDA levels(P＜0.01);and upregulated protein expressions of TNF-α,IL-1β,IL-6,TLR4 and p-NF-κB p65,as well as LncRNA H19 mRNA expression(P＜0.05,P＜0.01).Compared with the model group,the group intervened with high-dose Xuesaitong Capsules displayed reduced wound areas(P＜0.01);decreased serum levels of hs-CRP,TXB2 and ET(P＜0.05,P＜0.01);increased 6-K-PGF1α and NO levels(P＜0.05,P＜0.01);enhanced SOD activity(P＜0.05,P＜0.01);reduced MDA level in skin tissues(P＜0.05,P＜0.01);and down-regulated TNF-α,IL-1β,IL-6,TLR4 and p-NF-κB p65 protein expressions and suppressed LncRNA H19 mRNA expression in skin tissues as well(P＜0.05,P＜0.01).CONCLUSION Xuesaitong Capsules alleviate ischemia/reperfusion injury in frostbite-injured mice by exerting anti-inflammatory and anti oxidative stress effects and restoring vascular endothelial function mediated by the downregulation of LncRNA H19 expression and inhibition of the TLR4/NF-κB signaling pathway.

This study was aimed atanalyzing the epidemic characteristics of dengue fever in Ruili City atthe China-Myanmar bor-der in late 2023,to provide evidence for local dengue fever prevention and control measures.Adult Aedes mosquitoes were collected from Ruili City with a backpack type mosquito sucking machine in October of 2023.Serum samples frompatients with suspected den-gue were collected in acutephase,in November of 2023.Detection ofdengue virus(DENV)nucleic acids in Aedesmosquitoes and acute phase serum samples from suspected dengue fever patients using reverse transcription-polymerase chain reaction,and nucleic acid positive samples were inoculated into Vero cells for viral culture.After three consecutive blind passage,samples with cytopathic effect(CPE)were collected for be sequencingand analysisof genetic and evolutionary information.Dengue case characteristics were analyzed through descriptive epidemiological methods.Among the 109 cases of dengue fever,the ratio of males to females was 1.27∶1.The youngest patient was 1 year old,the oldest patient was 84 years old,the age group of 20～59 years accounted for 73.39%,and the major-ity of occupations were freelancer(40.37%).A total of 827 female Aedes albopictus and 312 Aedes aegypti were collected,all of which tested negative for DENV nucleic acid.109 serum samples tested positive for DENV nucleic acid,including 49 DENV-1 and 60 DENV-2.Moreover,five DENV-1 and nine DENV-2 samples were obtainedthrough third-generation blind passaging with CPE.The E gene sequences of these five DENV-1 strains were detected,all were found to belong to DENV-1 genotype I,and had same evolu-tionary branch as the 2023 Guangzhou,China(PP563911),the 2019 Myanmar(MW793710),and 2019 Attapeu,Laos(MW559046).The nucleotide and amino acid sequence similarityamong the five DENV-1 genotype was 99.4%-99.9%and 99.8%-100.0%.Compared with the aforementioned epidemic strains,their nucleotide similarities were 99.5%-100.0%,99.4%-99.6%and 99.3%-99.5%,respec-tively,and amino acid similarity was 99.8%-100.0%.Nine DENV-2 E gene sequences were of Asian genotype I and belonged to the same evolutionary branch as the 2018 Myanmar(MW788982),2019 Hangzhou(OP684212)and 2019 Ruili(OQ928150).The nucleotide and amino acid similarities of the nine samples were 99.5%-100.0%and 99.8%-100.0%,respectively.Compared with the aforementioned epidemic strains,their nucleotide similarities were 99.7%-100.0%,99.3%-99.7%and 99.3%-99.7%,respectively,and the amino acid similarity was 99.8%-100%,99.8%-100.0%and 99.4%-99.6%,respectively.Two dengue vectors,Aedes albopictus and Aedes aegypti,were present in Ruili city,and the dengue outbreak was caused primarily by DENV-1 genotype I and DENV-2 Asian genotype I in later 2023.The sources of DENV-1 were probably the same as those of DENV-1 with Guangzhou(2023),and the sources of DENV-2 were probably from Myanmar.Dengue cases were found primarilyin the 20-59 year age group and freelancers,thus suggesting that relevant local departments should strengthen surveillance of dengue imported case and vector.

Background and Aims:Acute inferior vena cava thrombosis(IVCT)commonly occurs secondary to inferior vena cava filter(VCF)implantation.If not promptly treated,it may lead to serious complications such as bilateral lower limb swelling and pulmonary embolism and can also reduce the likelihood of successful filter retrieval.Percutaneous mechanical thrombectomy(PMT)and catheter-directed thrombolysis(CDT)are currently the main interventional treatments for IVCT,but comparative studies evaluating their efficacy and safety remain limited.This study was to conduct a prospective randomized controlled trial to compare the clinical efficacy and safety of AngioJet mechanical thrombectomy versus conventional CDT in the treatment of acute IVCT and to explore factors influencing filter retrieval rates,thereby providing evidence-based guidance for clinical decision-making.Methods:From January 2022 to December 2024,patients diagnosed with acute IVCT following VCF implantation were prospectively enrolled at the Department of Vascular Surgery,Beijing Jishuitan Hospital,Capital Medical University.Patients were randomly assigned to either the CDT group(n=46)or the PMT group(n=48)according to the interventional procedure used.The two groups were compared in terms of filter retrieval rates,thrombus clearance outcomes,operative time,thrombolytic drug dosage,and incidence of complications.Logistic regression analysis was used to identify factors associated with primary filter retrieval.Results:A total of 94 patients were enrolled,with 46 in the CDT group and 48 in the PMT group.Compared to the CDT group,the PMT group demonstrated a significantly higher primary filter retrieval rate(77.1%vs.43.5%),grade Ⅲ thrombus clearance rate(70.8%vs.37.0%),and better postoperative thrombus scores.Additionally,the PMT group required lower urokinase doses and shorter thrombolysis duration(all P<0.05).The overall filter retrieval rate and 3-month IVC patency were similar between groups,both exceeding 93%.Regarding safety,the CDT group had a higher incidence of catheter-related infections and medical adhesive-related skin injury,while vagal reflex symptoms were more frequent in the PMT group.Logistic regression analysis identified thrombus clearance rate as an independent factor significantly associated with primary filter retrieval in the PMT group(OR=190.773,P<0.05).Conclusion:Compared to CDT,AngioJet mechanical thrombectomy combined with manual aspiration achieves higher thrombus clearance and primary filter retrieval rates in the treatment of acute IVCT while also reducing thrombolysis duration and drug dosage.However,attention should be paid to the increased risk of vagal reflex symptoms.There was no significant difference between the two groups in secondary filter retrieval rates or long-term IVC patency.The choice of intervention should be based on the patient's condition,timing of filter retrieval,and individualized clinical considerations.

Objective:To investigate the clinical application value of a novel filter's retraction hook capture technique of pull-assisted method for the endovascular retrieval of conical inferior vena cava (IVC) filters whose hook attached to the wall.Methods:From January 2020 to December 2024, patients with conical filters whose hook attached to the wall admitted at Beijing Jishuitan Hospital were enrolled consecutively.Results:A total of 46 patients underwent filter retrieval using filter's retraction hook capture technique of pull-assisted method. Among these patients, 39 cases (84.8%) were successful in filter retrieval, with the penetration distance of cranial anchor vertex of 3.3(2.5, 4.4) mm, and 13 (33.3%) filters were deformed. The other 7 cases were unsuccessful, with a penetration distance of cranial anchor vertex of 5.0 (4.3, 5.0) mm, and 6 (85.7%) filters were deformed. There was a statistically significant difference between the two groups ( P<0.05). One case (2.2%) had IVC injury, one case (2.2%) experienced filter fracture, and no symptomatic pulmonary embolism occurred. Logistic regression analysis showed that filter deformation was an independent dangerous factor for filter's retraction. Conclusions:Filter's retraction hook capture technique of pull-assisted method is effective in removing conical filters whose hook attached to the wall, with no symptomatic PE occurring. This method can be considered as a new adjuvant technique for filter retrieval.
