Acupuncture Ameliorates Depression-Like Behaviors Through Modulating the Neuroinflammation Mediated by TLR4 Signaling Pathway in Rats Exposed to Chronic Restraint Stress.

Recently, emerging evidence has identified that stress-induced activation of neuroinflammation is considered to be one of the most prevalently precipitating factors in the pathogenesis of depression. Data from clinical trials and experimental findings has verified the efficacy and safety of acupuncture in the prevention and treatment of depression. However, the mechanism of the preventive effect of acupuncture for depression has not been fully elucidated.

[Effect of Electroacupuncture at Distal and Proximal Acupoints on Expression of Spinal p 38 Mitogen-activated Protein Kinase and Cyclic Adenosine 3',5'-monophosphate in Rats with Lumbago].

Objective: To observe the influence of Electroacupuncture (EA) stimulation of different distal-proximal acupoints combination groups on pain reaction, spinal p 38 mitogen-activated protein kinase (p 38 MAPK) expression and cyclic adenosine 3', 5'-monophosphate (cAMP) content in experimental lumbago rats.

Methods: Seventy-eight male SD rats were randomized into normal, model, sham operation, EX-B 2-BL 25 (proximal acupoints, PA), BL 40-BL 60 (distal acupoints, DA) and DA+PA groups. The lumbago model was established by implanting the autologous nucleus pulposus to the site close to the left L 5 dorsal root ganglion and the surface of dura mate of spinal cord.

[Development of Researches on Mechanisms of Acupoint Combination for Some Disorders in Nerve-humoral-immunological Modulation].

Proper combination of acupoints is one of the core issues of acupuncturology, and is also one of the factors affecting clinical outcomes. In the present paper, the authors make a review on the development of researches on the underlying mechanisms of acupoint combination for some clinical disorders from nerve system, humoral factors and immunological regulation. The neural mechanism involves both the peripheral nervous system (mainly the segmental innervation) and central nervous system (spinal cord, brainstem, hypothalamus, cerebral cortex and cerebellum) , while the humoral factors chiefly contain neurotransmitters and hormones of the endocrine system.
