Pure solid lung cancer is associated with higher lymph node metastasis rates, therefore identifying the risk factors and metastatic patterns of lymph node involvement in early-stage pure solid lung cancer is a critical research topic. We retrospectively collected preoperative Computed Tomography (CT) imaging and postoperative pathological data of patients with pure solid lung cancer from 2021 to 2025 to investigate the risk factors and patterns of lymph node metastasis. Among 8718 patients, 104 with ≤ 2 cm pure solid lung cancer were analyzed, with a lymph node metastasis rate of 20.

Sonodynamic therapy (SDT), a noninvasive treatment modality that combines low intensity ultrasound with sonosensitizers, has shown significant potential in the treatment of cancer and metabolic diseases. However, SDT induced autophagy plays a dual role in disease progression, as it can promote either cell survival or cell death, and its effects are highly dependent on cell type and pathological context. This complexity underscores the urgent need for regulation of autophagy to optimize the therapeutic efficacy of SDT.

Neuropathic pain is a persistent and treatment-resistant condition often linked to neuroinflammation and pyroptosis in the spinal cord. The NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome has emerged as a key contributor to this process. Here we investigate the efficacy of bergapten (5-Methoxypsoralen), a natural compound with anti-inflammatory activity, in managing neuropathic pain.

Background: Population aging has led to accelerated decline in pulmonary function, rising prevalence of depressive symptoms, and cognitive impairment, posing significant public health challenges. Although epidemiological evidence links poorer pulmonary function to subsequent cognitive decline, the pathways driving this relationship are not fully understood. We therefore investigated whether depressive symptoms mediate this relationship in older Chinese adults.

Maize is one of the major crops that are susceptible to infection and subsequent aflatoxin contamination, which poses a serious health threat to humans and domestic animals. Here, an RNA interference (RNAi) approach called Host-Induced Gene Silencing (HIGS) was employed to suppress the -methyl transferase gene (, also called ), a key gene involved in aflatoxin biosynthesis. An RNAi vector carrying part of the gene was introduced into the B104 maize line.

Metal-halogen exchange reactions are fundamental processes in chemistry that transform organic halides into organometallic reagents. However, using these reactions to build intricate structures in a cascade manner, especially in a catalytic mode, has been a challenge. In this study, we introduce a homoleptic organolanthanum catalyst to initiate lanthanum-halogen exchange and intramolecular carbohalogenation.

Establishing reliable noninvasive tools to precisely diagnose clinically significant liver fibrosis (SF, ≥F2) remains an unmet need. We aimed to build a combined radiomics-clinic (CoRC) model for triaging SF and explore the additive value of the CoRC model to transient elastography-based liver stiffness measurement (FibroScan, TE-LSM). This retrospective study recruited 595 patients with biopsy-proven liver fibrosis at two centers between January 2015 and December 2021.
