Objective: The primary cause of microvascular disease in diabetic complications is long-term hyperglycemia, wherein the damage and apoptosis of vascular endothelial cells play a significant role. Sodium tanshinone IIA sulfonate(STS) has been found to have beneficial effects on cardiovascular health. This study aimed to investigate the impact of STS on high glucose-induced apoptosis and oxidative stress damage in vascular endothelial cells, as well as its potential protective mechanisms. Methods:Human umbilical vein endothelial cells(HUVECs) were divided into five groups:low-glucose group, high-glucose group, and three STS groups(STS-a, STS-b, and STS-c). The low-glucose group was incubated with DMEM low-sugar medium containing 5.5 mmol·L-1glucose, while the high-glucose group was treated with 33.3mmol·L-1glucose. The STS groups were exposed to 10, 30, and 50 μg·m L-1of STS,respectively. Each group was cultured for 72 h, and the MTT method was utilized to assess cell proliferation. Additionally, flow cytometry was employed to monitor changes in cell apoptosis and cellular oxidative stress indicators at 24, 48, and 72 h of cell culture in each group. Results: As time went on, the cell proliferation ability and apoptosis rate of each group gradually increased. The high-glucose group exhibited lower proliferation ability compared to the other groups. The STS-c group demonstrated the highest OD value for proliferation ability(24 h: 1.19±0.12; 48 h: 1.20±0.13; 72 h:1.25 ±0.12), but it was still lower than that of the low-sugar group. Notably, the high-glucose group had the highest cell apoptosis rate, while the low-glucose group had the lowest. The apoptosis rate of the STS-c group(24 h: 8.02±0.13; 48 h: 10.10±0.12;72 h: 13.18 ±0.11)% was between that of the low-glucose group and the high-glucose group, and lower than the STS-a and STS-b groups. Furthermore, the high-glucose group exhibited the highest malondialdehyde and nitric oxide synthase activities, as well as super

Objective: To investigate the effect of down-regulation of matrix metalloproteinase-2(MMP-2) by down-regulating the cyclic adenosine monophosphate(cAMP) signaling pathway on the migration and invasion of uterine fibroids ***: A total of 65 female SD rats were randomly divided into five groups after being adaptively fed for 7 d. Except for the blank group, the remaining four groups of rats were injected with 0.05 mg/(100 g·d) estradiol benzoate and 0.5 mg/(100g·d) progesterone into the muscle to establish a uterine fibroids rat model. After successful modeling, the blank group and model group were given 200 mg/(kg·d) physiological saline by gavage,the low-dose group was given 100 mg/(kg·d) mifepristone by gavage, the medium-dose group was given 200 mg/(kg·d) mifepristone by gavage, and the high-dose group was given 300 mg/(kg·d) mifepristone by gavage. After continuous gavage treatment for 21 d,serum and uterine tissues were collected from rats to observe and compare the expression levels of MMP-2 mRNA, TIMP-2 mRNA, estradiol(E2), cAMP signaling pathway related proteins, and the migration and invasive ability of uterine fibroids cells in the five groups of rats. Results: The expression levels of MMP-2 mRNA and E2in the high-dose group were lower than those in the low-dose group and the medium-dose group, and the expression level of TIMP-2 mRNA was higher than that in the low-dose group and the medium-dose group(P<0.05). The number of cell migration in a single visual field of rats in the high-dose group was lower than that in the low-dose group and the medium-dose group(P<0.05). The number of cell invasion in a single visual field of rats in the high-dose group was lower than that in the low-dose group and the medium-dose group(P<0.05). The mRNA expression levels of cAMP, PDE and PK in the high-dose group were higher than those in the low-dose group, and the mRNA expression levels of AC in the high-dose group were lower than those in the low-dose group(P<0.
