Ferroptosis, a New Insight Into Acute Lung Injury.

Acute lung injury (ALI), a common and critical illness with high morbidity and mortality, is caused by multiple causes. It has been confirmed that oxidative stress plays an important role in the development of ALI. Ferroptosis, a newly discovered programmed cell death in 2012, is characterized by iron-dependent lipid peroxidation and involved in many diseases.

Total Flavones of Abelmoschus manihot Exhibits Pro-Angiogenic Activity by Activating the VEGF-A/VEGFR2-PI3K/Akt Signaling Axis.

Angiogenesis is a process of new blood vessel formation from pre-existing vessels. Vascular endothelial growth factor-A (VEGF-A) binds to VEGF receptor-2 (VEGFR2) and thus activation of phosphatidylinositol 3-kinase (PI3K)/Akt pathway play a central role in angiogenesis. Total flavones of Abelmoschus manihot (TFA), the major active component of the traditional Chinese herb Abelmoschus manihot, display novel pro-angiogenic activity.

Total flavones of enhances angiogenic ability both and .

Angiogenesis is a process of new blood vessel formation from pre-existing vessels. It is a normal and vital process in growth and development, as well as in wound healing and in the formation of granulation tissue. Total flavones of (TFA) are the major constituents of the traditional Chinese herb L.

[Effects of ligustrazine injection on high glucose-induced type I collagen, matrix metalloproteinase-1 and tissue inhibitor of metalloproteinase-1 expressions in human peritoneal mesothelial cells in vitro].

Objective: To investigate the effects of ligustrazine injection on type I collagen, matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) expressions in human peritoneal mesothelial cells (HPMCs) cultured in high glucose conditions.

Methods: HPMCs were isolated from human omenta by trypsin digestion method and subcultured. Then, the HPMCs were divided into normal control group, high glucose group and high glucose plus low-, medium- and high-dose ligustrazine (10, 20 and 40 mg/L ligustrazine respectively) groups.
