Midkine promotes thyroid cancer cell migration and invasion by activating the phosphatidylinositol 3 kinase/protein kinase B/mammalian target of rapamycin pathway.

Objective: Thyroid cancer (TC) therapy, which is routinely used at present, can improve patients' survival rates. However, lymph node metastasis results in a higher degree of TC malignancy in patients who experience recurrence and/or death. The elucidation of new mechanisms of TC metastasis can help identify new therapeutic targets.

Differentiating progressive supranuclear palsy from other movement disorders using transcranial sonography: a systematic review and meta-analysis.

Progressive supranuclear palsy (PSP) is an atypical parkinsonism that presents with different phenotypes. There are still no validated diagnostic biomarkers for early diagnosis of PSP. Transcranial sonography (TCS) is a promising tool in the differential diagnosis of parkinsonian disorders; however, there are no systematic investigations about the application of TCS in PSP patients.

Ultrasonography-based radiomics and computer-aided diagnosis in thyroid nodule management: performance comparison and clinical strategy optimization.

Objectives: To compare ultrasonography (US) feature-based radiomics and computer-aided diagnosis (CAD) models for predicting malignancy in thyroid nodules, and to evaluate their utility for thyroid nodule management.

Methods: This prospective study included 262 thyroid nodules obtained between January 2022 and June 2022. All nodules previously underwent standardized US image acquisition, and the nature of the nodules was confirmed by the pathological results.

Lignan Glucosides from the Stem Barks of Illicium difengpi.

In this study, four new lignan glucosides, named difengpiosides A-D (1-4), were isolated from the stem barks of Illicium difengpi, together with seven known compounds 5-11. Their structures were identified on the basis of spectroscopic analyses (1D and 2D NMR, HRESIMS, CD) and a comparison with literature data. All the compounds were evaluated for their inhibitory effects on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW264.

[Chemical constituents from EtOAc fraction of Sophora dunnii].

Sixteen compounds have been isolated from the EtOAc fraction of 95% ethanolic extract of Sophora dunnii through silica gel, Sephadex LH-20 and semi-prerarative HPLC column chromatographies. Their structures were identified on the basis of NMR and MS spectra data as phaseollidin (1), L-maackiain (2), 2-(2',4'-dihidroxyphenyl)-5,6-methylenedioxy benzofuran (3), 8-demethyl-farrerol (4), liquiritigenin (5), genistein (6), 6-methylgenistein (7), 5-O-methyl genistein (8), 7,2',4'-trihydroxys-5-methoxy-isoflavanone (9), 7, 3', 4'-trihydroxy-isoflavanone (10), erythribyssin D (11), calycosin (12), trans-resveratrol (13), cis-resveratrol (14), stigmasterol (15), β-sitosterol (16). Among these, compounds 1-14 and 16 were isolated from this plant for the first time.
