Research progress of histone deacetylase 6 inhibitors in the therapy of ischemic stroke / 生理学报

The protein acetylation by histone acetyltransferases (HATs) and histone deacetylases (HDACs) plays a significant role in the development and maturation of the nervous system. HDAC6, belonging to class II HDACs, by regulating the survival, differentiation and maturation of neural cells, plays an important role in the development of the nervous system and participates in multiple pathological processes of cerebral ischemic injury. In addition, HDAC6 participates in the regulation of cognition and emotion of the brain. This article summarized the latest research results in recent years and expounded that HDAC6 inhibitors could produce a positive and effective neuroprotective effect on ischemic stroke by reducing the neuronal damage induced by excitotoxicity and oxidative stress, depressing the release of inflammatory mediators, inhibiting the apoptosis of neurons and promoting the growth of nerve and blood vessel.

The expression and significance of CD151 in pituitary adenomas / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To investigate the expression and significance of CD151 in pituitary adenomas.</p><p><b>METHODS</b>Thirty-six pituitary adenomas were collected immediately after surgery together with five normal pituitary tissue. Real time-PCR, Western blot and immunohistochemistry analysis were performed to detect the expression of CD151 mRNA and protein in thirty-six pituitary adenomases and five normal pituitary tissues.</p><p><b>RESULTS</b>The expression of CD151 in all pituitary adenomases was observed to be significantly higher than that in normal pituitary tissues by Western blot, real time PCR, and immunohistochemistry analysis (P < 0.01). The expression levels of protein and mRNA in invasive pituitary adenomas were much higher than those in non-invasive pituitary adenomas (P < 0.01).</p><p><b>CONCLUSION</b>The results suggested that the expression of CD151 was closely correlated with malignant degree of pituitary adenomas, which indicated the expression of CD151 was intimately correlated with occurrence and development of pituitary adenomas. Detecting CD151 might be a vital index to predict prognosis of pituitary adenomas.</p>

Preparation and in vitro study on diffusion of capsaicin cubosome / 中国中药杂志

This study was to investigate the permeability and absorbability of capsaicin cubosome across abdominal skin of the SD rats in vitro. Diffusion of capsaicin cubosome and cream was performed with the modified Franz diffusion cell technique. The capsaicin cubosome showed no enhancement of skin permeation within 24 hours. However, the deposition amounts of capsaicin in the rat skin in the cubosome group was markedly higher than those in the commercial cream group (P < 0.01). Cubosome showed excellent characetristic of skin-targed which could be a good carrier for the local transdermal drug delivery system.
