Electroacupuncture Promotes Motor Function Recovery in MCAO/R Rats by Activating Astrocyte-Related PI3K/AKT Pathway.

Background: Electroacupuncture (EA) is a widely used traditional Chinese medicine method to manage various diseases, including cerebral ischemia-reperfusion injury (CIRI).

Objectives: We assessed the neuroprotective effects of EA and examined its mechanism in a rat model of the middle cerebral artery occlusion-reperfusion (MCAO/R). The gait analysis was performed to evaluate the neuroprotective effects.

[Influence of electroacupuncture of"Zusanli"(ST36)on mast cells/TRPV1 signaling pathway in visceral hypersensitivity rats with functional dyspepsia].

Objective: To explore the interventional mechanism of electroacupuncture (EA) of "Zusanli"(ST36)based on the involvement of mast cells/ transient receptor potential vanilloid type1 (TRPV1) signaling pathway in relieving visceral hypersensitivity in functional dyspepsia (FD) rats.

Methods: Sixty SD rats (half male and half female, 10 days in age) were randomly divided into normal control, model, medication (ketotifen) and EA groups, with 15 rats in each group. The FD model was established by gavage of iodoacetamide combined with tail clamping (stress stimulation).

Objective: To observe the effect of electroacupuncture (EA) at "Zusanli" (ST 36) on duodenal mast cells, nerve growth factor (NGF) and neurotrophic tyrosine kinase receptor type 1 (NTRK1), and to explore the mechanism of electroacupuncture at Zusanli (ST 36) on functional dyspepsia (FD).

Methods: Sixty SPF-grade 10-day-old SD rats were randomly divided into a normal group, a model group, a ketotifen group and an EA group, 15 rats in each group. The FD model was prepared by iodoacetamide combined with rat tail clamping method in the model group, the ketotifen group and the EA group.

[Effects of electroacupuncture at "Zusanli"(ST36) on ultrastructure and mitochondrial dynamics of skeletal muscle in rats with spleen qi deficiency syndrome].

Objective: To observe the effects of electroacupuncture (EA) at "Zusanli" (ST36) on the ultrastructure and mitochondrial dynamics of skeletal muscle tissue in spleen deficiency rats, so as to explore the partial action mechanism of EA at ST36 for spleen deficiency syndrome.

Methods: Twenty-four male SD rats were randomly divided into 4 groups: normal group, model group, ST36 group and non-acupoint group (＝6 in each group). The model of spleen qi deficiency syndrome was established by improper diet and exhaustive swimming.

[Electroacupuncture of "Zusanli" (ST 36) Raises Muscular Force by Adjusting AMPK/PGC-1 α Signaling in Rats with Chronic Fatigue Syndrome].

Objective: To observe the effect of electroacupuncture (EA) of "Zusanli" (ST 36) on mitochondrial oxidative stress of skeletal muscle in rats with chronic fatigue syndrome (CFS) based on adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK)/ peroxlsome proliferator-activated receptor-γ coactivator-1 α (PGC-1 α) signaling, in order to reveal its mechanism underlying improvement of CFS.

Methods: Forty SD rats were randomly divided into normal control, CFS model, EA-Zusanli (ST 36) and EA-non-acupoint groups (=10 rats in each group). The CFS model was established by forced exhausted load-bearing swimming (twice daily), chronic constraint (1 h) and sleep deprivation (20 h/day) for 14 days.
