[Effect of electroacupuncture on complement C1q and microglia phagocytosis in hippocampus of SAMP8 mice].

Objective: To observe the effect of electroacupuncture (EA) on the expression of Iba-1, complement C1q and CD68 in hippocampus of SAMP8 mice, so as to explore its mechanisms underlying improvement of Alzheimer's disease (AD).

Methods: Twenty-four male SAMP8 mice were randomly and equally divided into model and EA groups, and 12 SAMR1 mice were used as the control group. EA (2 Hz, 1.

[Effects of alpine meadow degradation on soil carbon, nitrogen, and carbon stable istope in Zoige Plateau.].

To investigate the differences of soil carbon, nitrogen, and carbon stable isotopes in Zoige wetland, we analyzed the abundance of carbon stable isotopes and the contents of carbon and nitrogen in soils of three kinds of retrogressive successional grasslands (swampy meadow, steppe meadow, and degraded meadow). The results showed that the δC values in the meadow soil of Zoige alpine wetland ranged from -26.21‰ to -24.
