Cells undergo glucose metabolism reprogramming under the influence of the inflammatory microenvironment, changing their primary mode of energy supply from oxidative phosphorylation to aerobic glycolysis. This process is involved in all stages of inflammation-related diseases development. Glucose metabolism reprogramming not only changes the metabolic pattern of individual cells, but also disrupts the metabolic homeostasis of the body microenvironment, which further promotes aerobic glycolysis and provides favourable conditions for the malignant progression of inflammation-related diseases. The metabolic enzymes, transporter proteins, and metabolites of aerobic glycolysis are all key signalling molecules, and drugs can inhibit aerobic glycolysis by targeting these specific key molecules to exert therapeutic effects. This paper reviews the impact of glucose metabolism reprogramming on the development of inflammation-related diseases such as inflammation-related tumours, rheumatoid arthritis and Alzheimer's disease, and the therapeutic effects of drugs targeting glucose metabolism reprogramming on these diseases.

OBJECTIVE
To establish a ultra-high-performance liquid chromatography-mass spectrum/mass spectrum(UPLC-MS/MS) method for the determination of anlotinib in human plasma and assessment of clinical application.
METHODS
Zanubrutinib was used as internal standard and the extraction process was performed through protein precipitation method using acetonitrile, followed by separation on an Ultimate XB-C18(100 mm×2.1 mm, 3.0 μm) column using acetonitrile and 10 mmol·L−1 ammonium acetate-0.1% formic acid step-elution gradient. The flow rate was 0.6 mL·min−1 and injection volume was 5 μL. The mass analysis was performed by positive ion electrospray ionization in multiple-reaction monitoring mode, and the mass spectrometer was set at m/z 408.1→339.1 for anlotinib and m/z 472.2→290.1 for internal standard, respectively. The specificity, standard curve and lower limit of quantification, precision and recovery, matrix effect and stability of the method and clinical application were investigated.
RESULTS
The method was validated over the concentration range of 1.0−100.0 ng·mL−1, with R2=0.998 4. The precision RSD was<9%, the recovery and matrix effect were 104.81%−107.32% and 102.54%−105.26%, respectively, and this method had good stability and was not affected by matrix effect. The method had been used for determined 52 advanced non-small cell lung cancer patients treated with anlotinib. The trough plasma concentration (Ctrough) was measured on day 43 after initiation of anlotinib treatment. Anlotinib Ctrough were higher than lower limit of quantitation (1.0 ng·mL−1) from 52 patients. The plasma concentration of anlotinib Ctrough was (11.38±4.29)ng·mL−1 with 37.66% coefficients of variation, which were shown large inter-patient variability.
CONCLUSION
This method is high sensitivity, specificity and accurate, and suitable for determination of anlotinib in human plasma.

Human-animal interaction has a long-standing tradition dating back to ancient times. With the rapid advancements in intelligent chips, wearable devices, and machine algorithms, the intelligent interaction between animals and electronic technology, facilitated by electronic devices and systems for communication, perception, and control, has become a reality. These electronic devices aim to implement an animal-centric working mode to enhance human understanding of animals and promote the development of animal intelligence and creativity. This article takes medium-sized and large animals as research objects, with the goal of developing their ability enhancement, and introduces the concept of “intelligent animal augmentation system (IAAS)”. This concept is used to describe the characteristics of such devices and provides a comprehensive overview of existing animal and computer interface solutions. In general, IAAS can be divided into implantable and non-implantable types, each composed of interface platforms, perception and interpretation, control and instruction components. Through various levels of enhancement systems and architectural patterns, intelligent interaction between humans and animals can be realized. Although existing IAAS still lack a complete independent interaction system architecture, they hold great promise and development space in the future. Not only can they be applied as substitutes for cutting-edge devices and transportation equipment, but they are also expected to achieve cross-species information interaction through intelligent interconnection. Additionally, IAAS can promote bidirectional interaction between humans and animals, playing a significant role in advancing animal ethics and ecological protection. Furthermore, the development of interaction models based on animal subjects can provide insightful research experiences for the design of human-computer interaction systems, thereby contributing to the more efficient realization of the ambitious goal of human-machine integration.

As a novel iron-dependent form of cell death, ferroptosis is characterized by the excessive accumulation of phospholipids containing polyunsaturated fatty acids (PUFA) on the cell membrane and peroxidation. Lipid droplets are always in the dynamic transition of generation and decomposition, play a central role in regulating lipid metabolism, and are always in the dynamic transition of generation and decomposition. Lipid droplet metabolism is closely related to the occurrence of ferroptosis and plays an important role in the disease caused by ferroptosis. This review firstly focuses on the lipid droplet metabolism process and its effects on the storage and release of PUFA, and further elucidates the regulatory mechanism and key regulatory proteins of lipid drop metabolism on ferroptosis, in order to reveal the intrinsic relationship between lipid droplets and ferroptosis, and provide a new strategy for disease prevention and treatment.
