Emodin Inhibits Lipopolysaccharide-Induced Inflammation by Activating Autophagy in RAW 264.7 Cells.

Objective: To investigate the effects of emodin on inflammation and autophagy in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages and reveal its underlying mechanism.

Methods: 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was conducted to find the appropriate dose for emodin.

[Effect of acupuncture combined with repetitive transcranial magnetic stimulation on motor function and cerebral hemodynamics in children with spastic cerebral palsy with spleen-kidney deficiency].

Objective: To investigate the clinical effect of acupuncture combined with repetitive transcranial magnetic stimulation in the treatment of children with spastic cerebral palsy with spleen-kidney deficiency, as well as its effect in improving cerebral hemodynamics.

Methods: A total of 220 children with spastic cerebral palsy were divided into observation group and control group using a random number table, with 110 children in each group. The children in the control group were given rehabilitation training and repetitive transcranial magnetic stimulation, and those in the observation group were given acupuncture in addition to the treatment in the control group.

CRMP1 Interacted with Spy1 During the Collapse of Growth Cones Induced by Sema3A and Acted on Regeneration After Sciatic Nerve Crush.

CRMP1, a member of the collapsin response mediator protein family (CRMPs), was reported to regulate axon outgrowth in Sema3A signaling pathways via interactions with its co-receptor protein neuropilin-1 and plexin-As through the Fyn-cyclin-dependent kinase 5 (CDK5) cascade and the sequential phosphorylation of CRMP1 by lycogen synthase kinase-3β (GSK-3β). Using yeast two-hybrid, we identified a new molecule, Speedy A1 (Spy1), a member of the Speedy/RINGO family, with an interaction with CRMP1. Besides, for the first time, we observed the association of CRMP1 with actin.

[The role of PKC to TNF-alpha induced beta-1, 4-galactosyltransferase-I expression in endothelial cells].

Aim: To investigate the role of protein kinase C (PKC) to regulate the expression of beta-1, 4-galactosyltransferase-I(beta-1, 4-GalT-I)and the influence to cytoskeleton and adherence ability of human umbilical vein endothelial cells(HUVECs) when stimulated by tumor necrosis factor (TNF-alpha).

Methods: Cultured HUVECs were pretreated by various PKC inhibitors or PMA, an excitomotor of PKC respectively for 30 minutes, then stimulated by TNF-alpha for 4 hours, beta-1, 4-GalT-I expression were detected by RT-PCR and Western blot, expression of beta-1, 4-galactosylated carbohydrate chains and cytoskeleton were assayed by immunofluorescence, adherence ability of HUVECs was observed by endothelial-monocyte cell adherence test.

Results: Up-regulated expression of beta-1, 4-GalT-I and beta-1, 4-galactosylated carbohydrate chains in HUVECs stimulated by TNF-alpha were suppressed by PKC inhibitors and increased by PMA.

[Temperature sensitivity of wheat plant respiration and soil respiration influenced by increased UV-B radiation from elongation to flowering periods].

Field experiment was carried out in the spring of 2008 in order to investigate the effects of increased UV-B radiation on the temperature sensitivity of wheat plant respiration and soil respiration from elongation to flowering periods. Static chamber-gas chromatography method was used to measure ecosystem respiration and soil respiration under 20% UV-B radiation increase and control. Environmental factors such as temperature and moisture were also measured.

[Therapeutic effect of scalp-acupuncture combined with exercise therapy on spastic cerebral palsy of the child].

Objective: To observe clinical therapeutic effect of scalp-acupuncture combined with exercise therapy on spastic cerebral palsy.

Methods: Eighty children of spastic cerebral palsy were randomly divided into a scalp-acupuncture plus exercise therapy group and a exercise therapy group, 40 cases in each group. The scalp-acupuncture plus exercise therapy group were treated with scalp-acupuncture and exercise therapy, with Yundongqu (the motor area), Pinghengqu (the balance area), Ganjuequ (the sensory area), etc.
