For patients with symptomatic non-acute intracranial artery total occlusion(NIATO),successful endovascular recanalization can improve the clinical prognosis of some patients.High-resolution magnetic resonance vessel wall imaging(HR-VWI)can qualitatively and quantitatively describe the characteristics of intracranial arterial lesions,which is helpful for preoperative evaluation,selecting suitable patients,guiding intraoperative treatment and regular follow-up.This article systematically reviewed the application progress of HR-VWI in the endovascular recanalization of NIATO,analyzed the correlation between HR-VWI characteristics and technical success rates for recanalization as well as perioperative complications,and discussed the limitations and future development directions of current research.

WDFY1 is a member of the protein family containing the WD repeat and FYVE structural domains,acting as a junction that assists the recruitment of downstream molecules by Toll-like receptor 3/4(TLR3/TLR4)and promotes the body's natural anti-viral and anti-bacterial immune response.In recent years,the role of WDFY1 has been successively reported in various disease models,such as neurological diseases,autophagy and tumors.This paper aims to provide a comprehensive review of the current state of WDFY1 research,encompassing its expression distribution,cell biological function and its role in disease development,and take a prospect on the potential of WDFY1 as a target in rheumatoid arthritis.

AIM:To investigate the antiviral effica-cy and mechanism of Qingre Xiaoyanning(QRXYN)in vivo,and provide experimental basis for their prevention and treatment of influenza A virus.METHODS:We constructed a mouse model infect-ed with influenza A H3N2 virus.To evaluate the therapeutic effect of QRXYN on influenza A virus,we measured the body weight changes,pathologi-cal changes in lung tissue,hemagglutination titer,and viral load in mouse.To evaluate the possible mechanism of QRXYN's anti influenza A virus infec-tion,we used the ELISA to measure the levels of TNF-α,IL-1β,IL-4,IFN-γ,and vascular cell adhesion molecule-1(VCAM-1)in mouse bronchoalveolar Ia-vage fluid;used flow cytometry to assess the pro-portions of macrophages(F4/80),helper T lympho-cytes(CD4+T lymphocytes),and natural killer(NK)cells in lung tissue;and used Western blotting to detect the expression of Toll-like receptor 4(TLR4),myeloid differentiation factor 88(MYD88),inhibitor of kappa B kinase-β(IKK-β),NF-kappa-B inhibitor al-pha(IκBα),and phospho-IKB alpha(p-IκBα)in lung tissue.RESULTS:Compared to the model group,both Oseltamivir and QRXYN can alleviate the se-verity of lung tissue lesions in mice,decrease the blood coagulation titer and viral load of mouse lung tissue(P＜0.01),lower the levels of TNF-α,IL-4,and VCAM-1 in bronchoalveolar lavage fluid(P＜0.05,P＜0.01),reduce the proportion of macro-phages(P＜0.05,P＜0.01),and increase the propor-tion of CD4+T lymphocytes and NK cells(P＜0.05,P＜0.01).Additionally,oseltamivir can reduce the ex-pression of MYD88 protein in mouse lungs(P＜0.05),while QRXYN can decrease the expression of IKK-β and P-IκBα proteins in mouse lungs(P＜0.05).CONCLUSION:QRXYN have good in vivo antiviral ef-fects against the influenza A virus,and their mecha-nism may be related to the regulation of the immu-nologic function and NF-κB signal pathway.

This article reports a case of extensive ocular inflammation following zoledronic acid infusion for the treatment of osteoporosis. The patient developed pain, eyelid edema, conjunctival congestion, and decreased vision in the right eye one day after receiving intravenous zoledronic acid, and was diagnosed with uveitis, scleritis, and periorbital soft tissue inflammation. The patient′s symptoms were evaluated using the clinical activity score(CAS). After high-dose corticosteroid pulse therapy combined with other comprehensive treatments, the symptoms improved markedly. This article reviews the incidence, clinical features, potential mechanisms, management, and prognosis of ocular adverse reactions induced by zoledronic acid, and highlights the importance of early recognition and timely treatment of ocular inflammation after zoledronic acid therapy.

Atherosclerosis is the most common cause of ischemic stroke. Antiplatelet aggregation is considered as the effective treatment for atherosclerotic ischemic stroke. Ticagrelor is a novel P2Y12 receptor antagonist, which has the advantages as rapid onset, strong effect, no need for liver metabolism activation and reversible platelet inhibition. Studies have confirmed that ticagrelor has a better therapeutic effect on ischemic stroke patients who are resistant to clopidogrel; especially in dual antiplatelet therapy, patients used ticagrelor have lower stroke risk and severe hemorrhage risk does not increase in these patients. This article reviews the recent advances in mechanism of ticagrelor and its application in acute ischemic stroke, with the aim of providing references for clinical application of ticagrelor.

Objective:To analyze the clinical features and genetic sequencing results of a patient with Kallmann syndrome(KS) carrying digenic mutations who initially presented with osteoporosis, and to enhance awareness of this disease phenotype.Methods:Clinical data were collected, and peripheral blood DNA was extracted for whole-exome sequencing. Relevant literature was reviewed to summarize phenotypes associated with digenic/oligogenic variants involving CHD7.Results:The patient exhibited back pain, delayed development of secondary sexual characteristics, and hyposmia. Laboratory tests revealed reduced sex hormones and gonadotropin levels, while pituitary imaging was unremarkable. Bone mineral density imaging confirmed osteoporosis, and thoracolumbar X-rays showed multiple vertebral compression fractures. Genetic analysis identified a heterozygous splice-site mutation in CHD7(c.2698-1G>T) and a heterozygous missense mutation in WDR11(c.439G>A: p.D147N). According to ACMG criteria, the CHD7 mutation was classified as pathogenic, while the WDR11 variant was defined as a variant of uncertain significance(VUS). Literature review indicated that 40% of KS patients with digenic/oligogenic variants involving CHD7 presented with hearing or ocular abnormalities.Conclusion:This study reports a novel CHD7 mutation and a previously undescribed digenic combination of CHD7 and WDR11 variants in a KS patient. CHD7 variants may be implicated in auditory or ocular involvement in KS cases with digenic/oligogenic inheritances. KS patients may also manifest skeletal abnormalities in addition to hypogonadotropic hypogonadism. Tailored management of sex hormones and osteoporosis therapies across life stages is essential for optimizing bone health in KS.

Peganum harmala L. (P. harmala) is a significant economic and medicinal plant. The seeds of P. harmala have been extensively utilized in traditional Chinese medicine, Uighur medicine, and Mongolian medicine, as documented in the Drug Standard of the Ministry of Health of China. Twelve novel tryptamine-derived alkaloids (1-12) and eight known compounds (13-20) were isolated from P. harmala seeds. Compounds 1 and 2 represent the first reported instances of tryptamine-derived heteromers, comprising tryptamine and aniline fragments with previously undocumented C-3-N-1' linkage and C-3-C-4' connection, respectively. Compounds 3-5 were identified as indole-quinazoline heteromers, exhibiting a novel C-3 and NH-1' linkage between indole and quinazoline-derived fragments. Compound 6 demonstrates the dimerization pattern of C-C linked tryptamine-quinazoline dimer. Compound 8 represents a tryptamine-derived heterodimer with a distinctive carbon skeleton, featuring an unusual spiro-tricyclic ring (7) and conventional bicyclic tryptamine. Compounds 9-11 constitute novel 6/5/5/5 spiro-tetracyclic tryptamine-derived alkaloids presenting a unique ring system of tryptamine-spiro-pyrrolizine. Compounds 1-3 and 6-11 were identified as racemates. Compounds 2, 7, 9, 10, and 12 were confirmed via X-ray crystallographic analysis. All isolated compounds (1-20) exhibited varying degrees of antiviral efficacy against respiratory syncytial virus (RSV). Notably, the anti-RSV activity of compound 12 (IC₅₀ 5.01 ± 0.14 μmol·L^-1) surpassed that of the positive control (ribavirin, IC₅₀ 6.23 ± 0.95 μmol·L^-1), as validated through plaque reduction and immunofluorescence assays. The identification of anti-RSV compounds from P. harmala seeds may enhance the development and application of this plant in antiviral therapeutic products.
