[Electroacupuncture preconditioning prevents urticaria by regulating inflammatory response in rats with urticaria].

Objectives: To observe the effect of electroacupuncture (EA) preconditioning at "Quchi" (LI11) and "Xuehai" (SP10) in prevention of urticaria.

Methods: Twenty-four male SD rats were randomly divided into control, model and preconditioning of EA (Pre-EA) groups (8 rats/group). The urticaria model was established by intradermal injection of dilute allogeneic antioalbumin serum at the spots of the bilateral symmetry of the spine on the back, and followed by tail venous injection of mixture solution of egg albumin diluent, plus 0.

Transcriptome and metabolome analyses revealed the response mechanism of pepper roots to Phytophthora capsici infection.

Background: Phytophthora root rot caused by the oomycete Phytophthora capsici is the most devastating disease in pepper production worldwide, and current management strategies have not been effective in preventing this disease. Therefore, the use of resistant varieties was regarded as an important part of disease management of P. capsici.

Efficacy of Sijunzi decoction on limb weakness in spleen Qi deficiency model rats through adenosine monophosphate-activated protein kinase/unc-51 like autophagy activating kinase 1 signaling.

Objective: To investigate the efficacy of Sijunzi decoction () on limb weakness in a rat model of spleen Qi deficiency (SQD), and to study its effect on mitophagy in skeletal muscle through adenosine monophosphate-activated protein kinase (AMPK) / unc-51 like autophagy activating kinase 1 (ULK1) signaling.

Methods: SQD model rats were produced by fasting combined with forced swimming method for 15 d. After model assessment, rats were randomly divided into four groups of 10 [low/middle/high (L/M/H) Sijunzi decoction dose groups and a normal saline (S) group].
