Electroacupuncture improves cognitive deficits and insulin resistance in an OLETF rat model of Al/D-gal induced aging model via the PI3K/Akt signaling pathway.

To investigate the effect of electroacupuncture (EA) on cognitive function and insulin resistance (IR) in an Al/D-gal-induced aging model for Alzheimer's disease (AD) using Ostuka Long-Evans Tokushima Fatty (OLETF) rats. The Al/D-gal-OLETF rats for AD were randomly divided into the EA and non-EA groups. Cognitive function was assessed using the Morris water maze (MWM).

Comparative Study of ROCK1 and ROCK2 in Hippocampal Spine Formation and Synaptic Function.

Rho-associated kinases (ROCKs) are serine-threonine protein kinases that act downstream of small Rho GTPases to regulate the dynamics of the actin cytoskeleton. Two ROCK isoforms (ROCK1 and ROCK2) are expressed in the mammalian central nervous system. Although ROCK activity has been implicated in synapse formation, whether the distinct ROCK isoforms have different roles in synapse formation and function in vivo is not clear.

[Effect of Electroacupuncture on Learning-memory Ability in Rats with Hypoxic-ischemic Encephalopathy].

Objective: To observe the effect of electroacupuncture (EA) on changes of learning-memory ability, psychomotor coordination and anxiety-like behavior of cerebral hypoxic-ischemia (CHI) young rats, so as to explore its protective effect on neurons under hypoxic-ischemic conditions.

Methods: SD rats (aged 7 days) were randomly divided into sham operation (sham, =12), model (=11), and EA groups (=12). In addition, 6 young rats in each group were used for observing the number of dendritic spines after Golgi staining.
