[Electroacupuncture reduces neuronal apoptosis in rats with spinal cord injury by regulating GSK-3β expression and its phosphorylation].

Objectives: To observe the effect of electroacupuncture (EA) stimulation of "Dazhui"(GV14) and "Mingmen" (GV4) of the Governor Vessel (GV) on the apoptosis of neurons in rats with spinal cord injury (SCI) by regulating the expression of glycogen synthase kinase-3β (GSK-3β) protein and its phosphorylation level, so as to reveal partial mechanism for the treatment of SCI with EA of GV.

Methods: A total of 45 male SD rats were randomly divided into sham-operation, model and EA groups, 15 rats in each group. The SCI model was established by using the modified Allen's percussion device.

Effects of electroacupuncture on glial scar generation in SCI model rats.

Spinal cord injury (SCI) is a commonly occurring and severe form of central nervous system (CNS) injury. Previous studies have demonstrated that electroacupuncture (EA) therapy promotes recovery from SCI. In this study, we observed changes in the glial scars of rats with SCI to gain insight into how EA therapy positively influences locomotor function.

Electroacupuncture in promoting neural repair after spinal cord injury: Inhibiting the Notch signaling pathway and regulating downstream proteins expression.

Spinal cord injury (SCI) is one of the serious central nervous system injuries and the incidence of SCI continues to increase. Previous studies have indicated that electroacupuncture (EA) is beneficial for promoting recovery after SCI. In the present study, we attempted to evaluate how EA can promote the neural repair in SCI model rats by observing changes in the Notch signaling pathway.

Electroacupuncture Ameliorates Depressive-Like Behaviors in Poststroke Rats via Activating the tPA/BDNF/TrkB Pathway.

Background: Electroacupuncture (EA) is a form of physical therapy that has been widely used in clinical practice in China. Post-stroke depression (PSD) is the most common neuropsychiatric complication after stroke. EA has been shown to have beneficial effects on PSD patients.

Intraspinal administration of interleukin-7 promotes neuronal apoptosis and limits functional recovery through JAK/STAT5 pathway following spinal cord injury.

It has been previously reported that the blockade of interleukin-7 receptor (IL-7R) promotes functional recovery following spinal cord injury (SCI), however, the direct function and molecular mechanism of IL-7 involved in this pathogenic process are unclear. Here, we report that, contrary to IL-7R blockade, the intraspinal administration of IL-7 limits functional recovery following SCI. In addition, IL-7 treatment promotes neuronal apoptosis in spinal cord lesions, which may be attributed to exacerbated focal inflammatory response, as shown by increased accumulation of activated microglia/macrophage and production of proinflammatory mediators.

Exosomes Derived From Pericytes Improve Microcirculation and Protect Blood-Spinal Cord Barrier After Spinal Cord Injury in Mice.

Spinal cord injury (SCI) often leads to severe and permanent paralysis and places a heavy burden on individuals, families, and society. Until now, the therapy of SCI is still a big challenge for the researchers. Transplantation of mesenchymal stem cells (MSCs) is a hot spot for the treatment of SCI, but many problems and risks have not been resolved.

[Effect of Electroacupuncture Stimulation at "Dazhui" (GV 14) and "Mingmen"(GV 4) on Cell Apoptosis of Spinal Cord and Expression of JNK Signaling Related Protein in Spinal Cord Injury Rats].

Objective: To observe the effect of electroacupuncture (EA) stimulation at "Dazhui" (GV 14) and "Mingmen" (GV 4) of the Governor Vessel at different time-points on spinal cord neuronal apoptosis and the expression of c-Jun N-terminal kinases (JNK) protein in spinal cord injury (SCI) rats, so as to reveal its mechanism underlying improving SCI.

Methods: A total of 108 male SD rats were randomly divided into normal control, SCI model and EA groups which were further divided into 1, 3 and 7 d subgroups (12 rats/subgroup, 6 rats in each subgroup for TUNEL or Western blot, separately). SCI model was established by using the modified Allen's method.

Electroacupuncture at (GV14) and (GV4) protects against spinal cord injury: the role of the Wnt/β-catenin signaling pathway.

Electroacupuncture at (GV14) and (GV4) on the Governor Vessel has been shown to exhibit curative effects on spinal cord injury; however, the underlying mechanism remains poorly understood. In this study, we established rat models of spinal cord injury using a modified Allen's weight-drop method. Ninety-nine male Sprague-Dawley rats were randomly divided into three equal groups: sham (only laminectomy), SCI (induction of spinal cord injury at T), and EA (induction of spinal cord injury at T and electroacupuncture intervention at GV14 and GV4 for 20 minutes once a day).

Effects of Electroacupuncture at Governor Vessel Acupoints on Neurotrophin-3 in Rats with Experimental Spinal Cord Injury.

In an effort to explore new, noninvasive treatment options for spinal cord injuries (SCI), this study investigated the effects of electroacupuncture (EA) for SCI rat models. SCI was induced by a modified Allen's weight-drop method. We investigated the response of EA at Dazhui (GV 14) and Mingmen (GV 4) acupoints to understand the effects and mechanisms of EA in neuroprotection and neuronal function recovery after SCI.

Alteration of behavioral changes and hippocampus galanin expression in chronic unpredictable mild stress-induced depression rats and effect of electroacupuncture treatment.

To explore new noninvasive treatment options for depression, this study investigated the effects of electric acupuncture (EA) for depression rat models. Depression in rats was induced by unpredictable chronic mild stress (UCMS) combined with isolation for 21 days. Eighteen male Sprague-Dawley rats were randomly assigned into three groups: control, model, and EA groups.

[Effects of electroacupuncture on circadian rhythm of temperature and melatonin in depression rats model induced by chronic stress].

Objective: To observe the effects of electroacupuncture (EA) on circadian rhythm of temperature and melatonin (MT) in depression rats model induced by chronic stress, so as to explore the biological mechanism of EA for depression.

Methods: Twenty-four SD rats were randomly divided into a control group, a model group and an EA group, 8 cases in each one. Rats in the control group were treated with normal diet for 21 days without any treatment.

Progress of animal research on electro-acupuncture treatment for depression(△).

This paper summarized the Chinese literatures in the previous 5 years about the pre-clinical animal researches on the application of electro-acupuncture (EA) treatment for depression, searched in China National Knowledge Infrastructure (CNKI). The efficiency of EA treatment for depression and the mechanism of it were discussed, to shed light on new ideas and new fronts for the further research on depression in clinical or pre-clinical fields.
