Abstract

To observe the effect of twirling-reducing needling on changes of profile of differentially-expressed genes in the hypothalamus in rats with stress-induced prehypertension (SI-PHT), so as to explore its mechanism under-lying improvement of prehypertension. Wistar male rats were randomly divided into blank control group (n=12), model group (n=12) and acupuncture group (n=10). The SI-PHT model was established by planta-electric-shock stimulation (30 V, 5 s) plus noise stimulation (80-100 db, 50 ms), twice daily, continuously for 11 days. Manual acupuncture stimulation (twirling-reducing needling) was applied to bilateral "Taichong" (LR 3) and "Quchi" (LI 11) for about 1 min (60 cycles/min), followed by retaining the needles for 20 min during modeling preparation, once daily for 11 days. The systolic blood pressure (SBP) and behavior changes were recorded before intervention and on the 3rd, 5th, 7th, 9th and 11th day during modeling. The expression (Fold change,|FC| ≥ 1.5) profile of genes in the hypothalamus was analyzed using Affymetrix GeneChip Rat Gene 2.0 ST Array, followed by analyzing the differentially-expressed genes involving the related biological process,molecular function, and signaling pathways by using Gene Ontology...Continue Reading

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.
