Electro-acupuncture treatment ameliorates intestinal inflammatory injury in cerebral ischemia-reperfusion rats via regulating the balance of Treg / γδ T cells.

Electro-acupuncture (EA) has an anti-inflammatory role in ischemic stroke, but whether the protective effect of EA involves the regulation of the intestine barrier and Treg/ γδ T cells is unclear. Cerebral ischemia-reperfusion (I/R) injury was induced by middle cerebral artery occlusion(MCAO) for 2 h followed by reperfusion for 24 h. The rats have treated with EA at the "Baihui" acupoint(GV20).

STAT3 but Not STAT5 Contributes to the Protective Effect of Electroacupuncture Against Myocardial Ischemia/Reperfusion Injury in Mice.

Electroacupuncture (EA) can help reduce infarct size and injury resulting from myocardial ischemia/reperfusion (I/R); however, the underlying molecular mechanism remains unknown. We previously reported that STAT5 plays a critical role in the cardioprotective effect of remote ischemic preconditioning (RIPC). Here, we assessed the effects of electroacupuncture pretreatment (EAP) on myocardial I/R injury in the presence and/or absence of in mice and investigated whether EAP exerts its cardioprotective effects in a STAT5-dependent manner.

Electroacupuncture improves cardiac function and reduces infarct size by modulating cardiac autonomic remodeling in a mouse model of myocardial ischemia.

Background: Sympathetic and parasympathetic nerve remodeling play an important role in cardiac function after myocardial ischemia (MI) injury. Increasing evidence indicates that electroacupuncture (EA) can regulate cardiac function by modulating the autonomic nervous system (ANS), but little is known about its effectiveness on neural remodeling post-MI.

Objectives: To investigate the role of EA in ANS remodeling post-MI.

[Effects of electroacupuncture on food intake and expression of lipid receptors of taste buds in the tongue and hippocampus in obese rats].

Objective: To observe the effect of electroacupuncture (EA) on food intake, body weight, number of taste bud cells and the expression of lipid taste bud receptor (CD36), Gα-gustducin, post-synaptic density protein 95 (PSD95) and neurofilament light chain (NFL) proteins in the tongue or hippocampus in obese rats, so as to explore its mechanism underlying reducing body weight.

Methods: A total of 30 male SD rats were randomly divided into control, model and EA groups (=10 in each group, 5 rats for H.E.

Epigenetic Landscape Changes Due to Acupuncture Treatment: From Clinical to Basic Research.

Acupuncture has been widely used for treating diseases since the ancient days in China, but the mechanism by which acupuncture exerts such powerful roles is unclear. Epigenetics, including DNA methylation, histone modification, and post-transcriptional regulation of miRNAs, is the study of heritable changes in gene expression that do not include DNA sequence alterations. Epigenetics has become a new strategy for the basic and clinical research of acupuncture in the last decade.

[Research and thinking of acupuncture on promoting white adipose tissue browning].

Acupuncture has become an effective approach in clinic for treating obesity, but its mechanism has not been clarified yet. A large number of researches have been conducted on the obesity mechanism in the aspects of neurophysiological regulation, feeding center regulation and peripheral digestion and absorption regulation at home and abroad. But, regarding the main storage site of excess energy, i．e.

Stat5-dependent cardioprotection in late remote ischaemia preconditioning.

Aims: To study the protective effects of late remote ischaemic preconditioning (RIPC) against myocardial ischaemia/reperfusion (I/R) injury and determine whether Stat5 is involved in this protection by using cardiomyocyte-specific Stat5 knockout mice (Stat5-cKO).

Methods And Results: Mice were exposed to lower limb RIPC or sham ischaemia. After 24 h, the left anterior descending artery (LAD) was ligated for 30 min, then reperfused for 180 min.

[Effect of Electroacupuncture on Adenosine Receptor Expression in White Adipose Tissue of Diet-induced Obese Mice].

Objective: To investigate the effects of electroacupuncture (EA) on the expression of adenosine receptor (AR) in the white adipose tissue (WAT) of diet-induced obese (DIO) mice, so as to reveal a peripheral mechanism of EA underlying improvement of body weight.

Methods: Forty three-week-old C 57 BL/6 male mice were divided into normal diet group (=12) and high fat diet group (=28) randomly, and fed by normal diet and high fat diet for 12 weeks, respectively. In the high fat diet group, mice with body weight over 20% heavier than that of the normal diet group were considered as obese mice.

Cardioprotective Effect of Electroacupuncture Pretreatment on Myocardial Ischemia/Reperfusion Injury via Antiapoptotic Signaling.

Objectives. Our previous study has used RNA-seq technology to show that apoptotic molecules were involved in the myocardial protection of electroacupuncture pretreatment (EAP) on the ischemia/reperfusion (I/R) animal model. Therefore, this study was designed to investigate how EAP protects myocardium against myocardial I/R injury through antiapoptotic mechanism.

[Acupuncture Intervention Reduced Weight Gain Induced by Hypoglycemic Agents through Food Intake-related Targets in Central Nervous System].

Clinical practice shows that thiazolidinediones (TZDs) induce weight gain in patients with type-II diabetes mellitus during treatment, which restrains its application and generalization clinically. It has been demonstrated that acupuncture therapy is useful in easing obesity in clinical trials. In the present paper, we summarize the underlying mechanism of weight gain induced by TZDs through food intake-related targets in the central nervous system and analyze the possible effects of acupuncture therapy.

Effects of Ziziphus jujuba fruit extracts on cytochrome P450 (CYP1A2) activity in rats.

Drug-drug interactions have become a serious problem in the clinic, since plant-based medicines are extensively used. The present study investigated the effects of Ziziphus jujuba fruit (ZJ) extract on the pharmacokinetics of phenacetin, a typical substrate of a cytochrome P450 enzyme CYP 1A2, in rats. The rats were pretreated with the water extract (1.

Tissue-specific alterations in expression and function of P-glycoprotein in streptozotocin-induced diabetic rats.

Aim: To investigate the changes of expression and function of P-glycoprotein (P-GP) in cerebral cortex, hippocampus, liver, intestinal mucosa and kidney of streptozocin-induced diabetic rats.

Methods: Diabetic rats were prepared via a single dose of streptozocin (65 mg/kg, ip). Abcb1/P-GP mRNA and protein expression levels in tissues were evaluated using quantitative real time polymerase chain reaction (QRT-PCR) analysis and Western blot, respectively.

Insulin suppresses the expression and function of breast cancer resistance protein in primary cultures of rat brain microvessel endothelial cells.

The aim of this study was to investigate the role of insulin in the regulation of breast cancer resistance protein (BCRP) function and expression using primary cultured rat brain microvessel endothelial cells (rBMECs) as an in vitro model of the blood brain barrier (BBB). The prazosin uptake assay and western blot analysis were used to assess the function and expression of BCRP, respectively. It was noted that the uptake of prazosin by rBMECs was time-, concentration- and temperature-dependent.
