Paeoniflorin ameliorates glycemic variability-induced oxidative stress and platelet activation in HUVECs and DM rats.

Glycemic variability (GV) plays an important role in the pathogenesis of vascular complications associated with diabetes mellitus (DM). Paeoniflorin is an effective Chinese traditional medicine with anti-inflammatory and immune-regulatory effects. Previous studies implicated the beneficial effects of paeoniflorin in treatment for diabetic complications, such as type 2 diabetic nephropathy and diabetes with myocardial ischemic injury.

Effect of Bushen Huoxue recipe on women with thin endometrial ovulation disorder and a rat model of thin endometrium resulted from kidney deficiency-related blood stasis.

To examine the therapeutic effect of Bushen Huoxue recipe (BHR) on women with thin endometrial ovulation disorder and on a rat model of kidney deficiency-related blood stasis. A total of 60 women with thin endometrial ovulation disorder was enrolled. The primary outcome of the study was the pregnancy rate three menstrual cycles after treatment.

A Protective Role of Paeoniflorin in Fluctuant Hyperglycemia-Induced Vascular Endothelial Injuries through Antioxidative and Anti-Inflammatory Effects and Reduction of PKC1.

Hyperglycemia fluctuation is associated with diabetes mellitus (DM) complications when compared to persistent hyperglycemia. Previous studies have shown that paeoniflorin (PF), through its antiapoptosis, anti-inflammation, and antithrombotic properties, effectively protects against cardiovascular and cerebrovascular disease. However, the mechanism underlying the protection from PF against vascular injuries induced by hyperglycemia fluctuations remains poorly understood.

Effect of tetramethylpyrazine and hyperlipidemia on hepcidin homeostasis in mice.

Iron homeostasis is strictly regulated in mammals, and disordered iron metabolism is recognized as a risk factor for various diseases, including cardiovascular disease. The hepcidin‑ferroportin axis is the key signaling mechanism that controls systemic iron homeostasis. Increased serum hepcidin is associated with multiple types of cancer and atherosclerosis (AS), and therapeutics that decrease hepcidin levels have been proposed to treat these diseases.

The Influence of Hyperlipidemia on Endothelial Function of FPN1 Tek-Cre Mice and the Intervention Effect of Tetramethylpyrazine.

Background/aims: Systemic iron homeostasis is strictly governed in mammals; however, disordered iron metabolism (such as excess iron burden) is recognized as a risk factor for various types of diseases including AS (Atherosclerosis). The hepcidin-ferroportin axis plays the key role in regulation of iron homeostasis and modulation of this signaling could be a potential therapeutic strategy in the treatment of these diseases. TMP (Tetramethylpyrazine) has been reported to have therapeutical effect on AS.

[Correlation Research on Blood Glucose Fluctuation in Type 2 Diabetes Mellitus Patients and Vas- cular Endothelial Injury/Platelet Activation/PKCβ1 Expression].

Objective To observe the correlation between blood glucose fluctuation in type 2 dia- betes mellitus ( T2DM) patients and vascular endothelial injury/platelet activation/protein kinase Cβ1 (PKCpβ1). Methods Capillary blood was collected from finger tips of 38 T2DM patients at 7 time points, i.e.

[The estrogen-like protective effect of ginsenoside Rb3 on oxidative stress and dysfunction of endothelial cells induced by oxidized low-density lipoprotein].

Ginsenoside Rb3 (GRb3) is one of the main components in plasma of Panax quinquefolius Saponin of stem and leaf (PQS), which can be into human plasma. Previous studies have found PQS has estrogen-like vascular protective effects. In the present study, we investigated the estrogen-like protective effect of GRb3 on oxidative stress and dysfunction of endothelial cells induced by oxidized low-density lipoprotein.

Effects of Panax quinquefolium saponin on phosphatidylinositol 3-kinase/serine threonine kinase pathway of neonatal rat myocardial cells subjected to hypoxia.

Objective: To explore the effects of Panax Quinquefolium Saponin (PQS) on phosphatidylinositol 3-kinase/serine threonine kinase (PI3K/Akt) pathway of neonatal rat myocardial cells subjected to hypoxia.

Methods: Neonatal rat myocardial cells were cultured in vitro. After the myocardial cell injury was induced by hypoxia, the cells were randomized into 5 groups: the normal group, the model group, the positive control group (Ciclosporin A, 2 µ mol/L), the low-dose PQS group (PQSL, 25mg/L), and the high-dose PQS group (PQSH, 50 mg/L).

The Expression of CD14(+)CD16(+) Monocyte Subpopulation in Coronary Heart Disease Patients with Blood Stasis Syndrome.

Blood stasis syndrome (BSS), a comprehensive pathological state, is one of the traditional Chinese medicine syndromes of coronary heart disease (CHD). In our previous study, we investigated that Fc γ RIIIA (also called CD14(+)CD16(+) monocyte subpopulation) is one of the differentially expressed genes related to CHD patients and its possible role in the atherosclerotic formation and plaque rupture. However, whether or not the deregulation of CD14(+)CD16(+) monocyte subpopulation expression is implicated in the pathogenesis of CHD patients with BSS has not yet been elucidated.

Ischemic postconditioning through percutaneous transluminal coronary angioplasty in pigs: roles of PI3K activation.

Background: Ischemic postconditioning (IPOC) has been suggested to reduce ischemic reperfusion injury. It remains unclear whether the activation of phosphatidylinositol 3 kinase (PI3K)/Akt is a causal mechanism in the cardioprotection afforded by IPOC, which was examined in the model of percutaneous transluminal coronary angioplasty (PTCA) minipigs.

Methods And Results: Minipigs underwent 45-min occlusion of the left anterior descending artery and 24-h reperfusion by PTCA.

Correlation between Fc γ R III a and aortic atherosclerotic plaque destabilization in ApoE knockout mice and intervention effects of effective components of chuanxiong rhizome and red peony root.

Objective: To explore the correlation between Fc γ RIII A (CD16A) and aortic atherosclerotic plaque destabilization in apoE knockout (apoE KO) mice and the intervention effects of effective components of chuanxiong rhizome and red peony root.

Methods: Eight 8-week-old male C57BL/6J mice were selected as the control group. Forty 8-week-old male apoE KO mice were randomly divided into the model group, apoE KO + intraperitoneal injection immunoglobulin group (IVIG), apoE KO + simvastatin group (Sm), apoE KO + high dosage of xiongshao capsule (XSC) group (XSCH), and apoE KO + low dosage of XSC group (XSCL), 8 mice in each group.
