Lung cancer is one of the cancers with the highest incidence in the world, and there is no standard treatment plan after second-line progression. Tumor angiogenesis has now been identified as an important therapeutic target for malignant tumors. Small molecule multi-target vascular kinase inhibitors can inhibit tumor angiogenesis by inhibiting angiogenesis-related signal pathways. At present, a lot of clinical trials of small molecule anti-angiogenic drugs for the treatment of non-small cell lung cancer (NSCLC) have been carried out, and some vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFR-TKIs) have been approved for the treatment of advanced NSCLC. Based on the development status of multiple small molecule anti-angiogenic drugs at home and abroad for the treatment of NSCLC, this article summarizes the efficacy and safety studies of multiple VEGFR-TKIs and fibroblast growth factor receptor (FGFR)-TKI single agents or combination treatments [including combined with chemotherapy, epidermal growth factor receptor (EGFR)-TKIs, immunotherapy, and radiotherapy, etc.] for NSCLC, and at the same time discussed the possible existence of VEGFR-TKIs drug resistance mechanisms and efficacy predictors, etc., and prospect the future development trend and potential problems of anti-vascular treatment of NSCLC, and provide new ideas for the follow-up precision and individualized treatment of lung cancer. .

Herin, the successful synthesis of a bis Schiff base (L) has been achieved using 2-hydroxy-1-naphthaldehyde and 1,3-diaminoguanidine as raw materials, which was further characterized by infrared spectroscopy, mass spectrometry, and nuclear magnetic resonance hydrogen spectrum. Moreover, spectroscopic experiments demonstrated that the probe L showed good selectivity and visual detectability for Al. Its detection limit (DL) is 2.

Biodegradable plastics (BPs) and lignite, both rich in organic matter, present significant challenges for efficient conversion into clean energy. This study examined the anaerobic co-digestion of BPs and lignite under controlled laboratory conditions. The results demonstrated that the co-digestion of polylactic acid (PLA) and lignite (at a 1:2 mass ratio, with 5 g PLA and 10 g lignite as the model system) rapidly acclimated to the anaerobic environment, enhancing cumulative biogas production by 57 % compared to the mono-digestion of lignite alone.

The CRISPR/Cas9 gene-editing technology, derived from the adaptive immune mechanisms of bacteria, has demonstrated remarkable advantages in fields such as gene function research and the treatment of genetic diseases due to its simplicity in design, precise targeting, and ease of use. Despite challenges such as off-target effects and cytotoxicity, effective spatiotemporal control strategies have been achieved for the CRISPR/Cas9 system through precise regulation of Cas9 protein activity as well as engineering of guide RNAs (gRNAs). This review provides a comprehensive analysis of the core components and functional mechanisms underlying the CRISPR/Cas9 system, highlights recent advancements in spatiotemporal control strategies, and discusses future directions for development.

The surge of antimicrobial resistance threatens efficacy of current antibiotics, particularly against Pseudomonas aeruginosa, a highly resistant gram-negative pathogen. The asymmetric outer membrane (OM) of P. aeruginosa combined with its array of efflux pumps provide a barrier to xenobiotic accumulation, thus making antibiotic discovery challenging.

Background: APG-115 is a novel small-molecule selective inhibitor that destabilizes the p53-MDM2 complex and activates p53-mediated apoptosis in tumor cells. Anlotinib inhibits tumor angiogenesis and promotes apoptosis. In this study, we investigated the apoptotic effect and potential mechanism of APG-115 and anlotinib combination on AML cell lines with different p53 backgrounds.
