Temporal profile of angiogenesis and expression of extracellular matrix-related genes in rat brains following experimental intracerebral hemorrhage.

Background: Angiogenesis is essential for the repair process after intracerebral hemorrhage (ICH).

Methods: Given the importance of the extracellular matrix (ECM) in angiogenesis, we analysed the temporal profile of angiogenesis in rat brains on days 4, 7, and 21 after ICH. To this end, we compared the expression of ECM-related genes between ICH-induced and sham-operated groups using a complementary DNA (cDNA) array.

Chitosan Hydrogel Delivery System Containing Herbal Compound Functions as a Potential Antineuroinflammatory Agent.

Rhein (4,5-dihydroxyanthraquinone-2-carboxylic acid) is an anthraquinone compound mainly isolated from the herbal medicine rhubarb. It possesses a wide spectrum of pharmacological effects. However, the lack of sustained release properties and the poor bioavailability hinder clinical transformation.

Methods: Collagenase type VII (0.5 U) was injected stereotaxically into right globus pallidus to induce ICH model.

decoction improves neurological dysfunction by increasing synapsin expression after traumatic brain injury.

Xuefu Zhuyu decoction has been used for treating traumatic brain injury and improving post-traumatic dysfunction, but its mechanism of action needs further investigation. This study established rat models of traumatic brain injury by controlled cortical impact. Rat models were intragastrically administered 9 and 18 g/kg Xuefu Zhuyu decoction once a day for 14 or 21 days.

Astragaloside IV Improves Vasodilatation Function by Regulating the PI3K/Akt/eNOS Signaling Pathway in Rat Aorta Endothelial Cells.

Coronary heart disease (CHD) remains a major public health burden. Endothelial-dependent coronary artery vasoreactivity is a significant indicator of vascular function. Endothelial dysfunction is characterized by decreased nitric oxide (NO) bioavailability and predicts late cardiovascular events.

Activation of the Notch-1 signaling pathway may be involved in intracerebral hemorrhage-induced reactive astrogliosis in rats.

OBJECTIVE Reactive astrogliosis, a key feature that is characterized by glial proliferation, has been observed in rat brains after intracerebral hemorrhage (ICH). However, the mechanisms that control reactive astrogliosis formation remain unknown. Notch-1 signaling plays a critical role in modulating reactive astrogliosis.

Plasma metabolomics profiles in rats with acute traumatic brain injury.

Traumatic brain injury (TBI) is a major cause of mortality and disability worldwide. We validated the utility of plasma metabolomics analysis in the clinical diagnosis of acute TBI in a rat model of controlled cortical impact (CCI) using gas chromatography/mass spectrometry (GC/MS). Thirty Sprague-Dawley rats were randomly divided into two groups of 15 rats each: the CCI group and sham group.

Hyperbaric oxygen for experimental intracerebral haemorrhage: Systematic review and stratified meta-analysis.

Objective: Hyperbaric oxygen (HBO) is widely used in treating various neurological diseases. However, HBO for treatment of intracerebral haemorrhage (ICH) remains controversial, in either animal or clinical studies. Therefore, we conducted this systematic review and meta-analysis on studies describing the efficacy of HBO in animal models of ICH.

2-Methoxyestradiol Inhibits Intracerebral Hemorrhage- Induced Angiogenesis in Rats.

Aim: Angiogenesis occurs after intracerebral hemorrhage (ICH). Hypoxia-inducible factor-1? (HIF-1?) is a critical regulator of angiogenesis. However, its role in the central nervous system remains controversial.

Leukemia Inhibitory Factor Contributes to Reactive Astrogliosis via Activation of Signal Transducer and Activator of Transcription 3 Signaling after Intracerebral Hemorrhage in Rats.

Reactive astrogliosis has occurred after intracerebral hemorrhage (ICH). Leukemia inhibitory factor (LIF) can act as a modulator for glial gene expression. Signal transducer and activator of transcription 3 (STAT3) is a critical regulator of reactive astrogliosis.

Is the Chinese medicinal formula Guipi Decoction () effective as an adjunctive treatment for depression? A meta-analysis of randomized controlled trials.

Objectives: To evaluate the effectiveness and safety of Guipi Decoction (, GPD) as an adjunctive in the treatment of depression.

Methods: A review of all relevant studies retrieved from a search of the following databases were conducted without any language restriction: Excerpt Medica Database (EMBASE), PubMed, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure (CNKI), VIP Information, Wanfang Data, and the Chinese Biomedical Literature Database. Papers published until February 2013 were taken into consideration.

Efficacy of deferoxamine in animal models of intracerebral hemorrhage: a systematic review and stratified meta-analysis.

Intracerebral hemorrhage (ICH) is a subtype of stroke associated with high morbidity and mortality rates. No proven treatments are available for this condition. Iron-mediated free radical injury is associated with secondary damage following ICH.

Buyang huanwu decoction promotes angiogenesis via vascular endothelial growth factor receptor-2 activation through the PI3K/Akt pathway in a mouse model of intracerebral hemorrhage.

Background: Intracerebral hemorrhage (ICH) is a fatal subtype of stroke that lacks effective treatments. Angiogenesis following ICH is an important response mediating brain recovery and repair. Phosphorylation of vascular endothelial growth factor receptor 2 (pVEGFR2) via PI3K/Akt signaling plays a key role in mediating cellular processes involved in repair, such as mitogenesis, angiogenesis, and vascular permeability.

Electroacupuncture improves recovery after hemorrhagic brain injury by inducing the expression of angiopoietin-1 and -2 in rats.

Background: Angiopoietin (Ang) is one of the major effectors of angiogenesis, playing a critical role in neurovascular remodeling after stroke. Acupuncture has been widely used for treating stroke in China for a long time. Recently, we have demonstrated that electroacupuncture (EA) can accelerate intracerebral hemorrhage (ICH)-induced angiogenesis in rats.

Angiogenesis opens a way for Chinese medicine to treat stroke.

Based on the pathophysiology of the brain, advance in angiogenesis induced by stroke, and evidences of Chinese-medicine-mediated angiogenesis, the possibility to study the stroke-treating mechanism of Chinese medicine in angiogenesis was discussed. And regarding our previous work on angiogenesis modulated by qi-tonifying and stasis-eliminating therapy following intracerebral hemorrhage, we proposed some questions, which should be taken into account in the further work.
