Effect of Acupuncture on Oxidative Stress Induced by Cerebral Ischemia-Reperfusion Injury

Area of Science:

• Integrative Medicine
• Cellular Biology
• Biochemistry

Background:

• Ischemia-reperfusion (I/R) injury is a significant clinical challenge.
• Oxidative stress, characterized by an imbalance between reactive oxygen species (ROS) and antioxidants, plays a critical role in I/R injury.
• Current treatments for I/R injury have limitations.

Purpose of the Study:

• To review the mechanisms by which acupuncture regulates oxidative stress in the context of I/R injury.
• To evaluate the therapeutic potential of acupuncture for preventing and treating I/R injury.

Main Methods:

• Systematic electronic literature search of PubMed, Clinical Key, and Cochrane Library up to November 2019.
• Keywords included: acupuncture, ischemia-reperfusion injury, oxidative stress, reactive oxygen species, and antioxidants.
• Review and synthesis of relevant preclinical and clinical studies.

Main Results:

• Acupuncture demonstrates efficacy in mitigating oxidative stress post-I/R injury.
• Acupuncture enhances the activity of endogenous antioxidant enzymes.
• Acupuncture downregulates the production of reactive oxygen species (ROS).
• Acupuncture aids in repairing cellular components (DNA, lipids, proteins) damaged by ROS.
• Acupuncture modulates apoptotic pathways influenced by ROS.

Conclusions:

• Acupuncture is a promising therapeutic strategy for managing oxidative stress associated with I/R injury.
• By modulating the redox balance and cellular repair mechanisms, acupuncture offers protective effects against I/R-induced damage.
• Further research into acupuncture's role in I/R injury is warranted.
