Mechanism of vascular endothelial cells ferroptosis in cervical spondylosis of vertebral artery type / 中国临床药理学与治疗学

Ferroptosis is a novel type of cell death, characterized by iron overload and lipid metabolism disorders, and is closely related to the occurrence of cardiovascular and cerebrovascular diseases, tumors, and acute injuries. When tissues and organs of the body are in a state of ischemia and hypoxia, iron ions initiate lipid peroxidation and produce a large number of oxygen free radicals. A series of oxidative stress reactions are more likely to trigger ferroptosis. In the process of cervical spondylosis of vertebral artery type, insufficient blood supply to the vertebral artery caused by degenerative changes of the cervical spine leads to imbalance of iron homeostasis and abnormal amino acid metabolism. Then ferroptosis is induced and plays an important role in the development of cervical spondylosis of vertebral artery type. This paper reviewed the mechanism of ferroptosis in the occurrence of cervical spondylosis of vertebral artery type, in order to provide new ideas and perspectives for the study of related problems of the disease.

Effect of Panlongqi Tablet on Cervical Spondylosis of Vertebral Artery Type in Rats / 中国实验方剂学杂志

Objective:To establish a model of cervical spondylosis of vertebral artery type （CSA） in rats by mixed modeling method， and observe the intervention effect of Panlongqi tablet （PLQT） on CSA rats. Method:SD rats were divided into a normal control group， a model group， low- （0.16 g·kg^-1）， medium- （0.32 g·kg^-1）， and high-dose （0.64 g·kg^-1） PLQT groups， and a Jingfukang granule （JFK， 1.35 g·kg^-1） group. The rats were treated correspondingly 24 hours after modeling for eight weeks， and those in the normal control group received an equal volume of normal saline by gavage. The limb movement was tested by the inclined plate assay， vertebral artery flow volume by multi-mode high-frequency sound wave for small animals， and microcirculatory blood flow in the pia mater by the laser Doppler. The imaging of the cervical spine was recorded and scored by X-ray micro-computed tomography （Micro CT）. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum levels of endothelin-1 （ET-1）， nitric oxide （NO）， tissue plasminogen activator （t-PA）， and plasminogen activator inhibitor （PAI）. Result:Compared with the normal control group， the model group showed decreased limb movement， vertebral artery flow volume， and microcirculatory blood flow in the pia mater， and increased imaging of the cervical spine and score （<italic>P</italic><0.05，<italic>P</italic><0.01）. PLQT could dose-dependently improve the motor function， increase the vertebral artery flow volume and microcirculatory blood flow in the pia mater， and reduce the degree and score of imaging of the cervical spine in CSA rats（<italic>P</italic><0.05，<italic>P</italic><0.01）. The serum levels of NO and t-PA were decreased and those of ET-1 and PAI were increased in the model group as compared with those in the normal control group， while such changes were reversed by PLQT treatment（<italic>P</italic><0.05，<italic>P</italic><0.01）. Conclusion:PLQT can enhance the limb movement， promote the vertebral artery flow volume and microcirculatory blood flow in the pia mater， improve the degree of imaging of the cervical spine， regulate the vasomotor function， and improve the coagulation and fibrinolysis system of CSA rats， which shows good potential for the treatment of CSA.
