[Electroacupuncture at "Zusanli"(ST36) protects intestinal mucosal immune barrier by suppre-ssing apoptosis of intestinal lymphocytes and regulating expression of Bcl-2 and Bax in sepsis rats].

Objective: To observe the effect of electroacupuncture (EA) at "Zusanli" (ST36) on apoptosis of intestinal T lymphocytes, translocation of intestinal bacteria and expression of intestinal Bcl-2 and Bax proteins and intestinal mucosal immune barrier in sepsis rats, so as to explore its underlying mechanism in relieving sepsis.

Methods: SD rats were randomly divided into sham operation (=6), model (=15), non-meridian and non-acupoint (non-acupoint, =15) and acupoint EA(=15) groups by using random number table method. The sepsis model was established by using cecal ligation and perforation(CLP) method.

Recombinant angiopoietin-like protein 4 attenuates intestinal barrier structure and function injury after ischemia/reperfusion.

Background: Intestinal barrier breakdown, a frequent complication of intestinal ischemia-reperfusion (I/R) including dysfunction and the structure changes of the intestine, is characterized by a loss of tight junction and enhanced permeability of the intestinal barrier and increased mortality. To develop effective and novel therapeutics is important for the improvement of outcome of patients with intestinal barrier deterioration. Recombinant human angiopoietin-like protein 4 (rhANGPTL4) is reported to protect the blood-brain barrier when administered exogenously, and endogenous ANGPTL4 deficiency deteriorates radiation-induced intestinal injury.

Palladium nanoparticles modified electrode for the selective detection of catecholamine neurotransmitters in presence of ascorbic acid.

Palladium (Pd) nanoparticles are directly fabricated on glassy carbon electrode (GCE) and indium tin oxide electrode (ITO) by simple electrochemical deposition process. The Pd nanoparticles modified ITO electrode surface has been studied in detail using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The electrodeposited nano Pd particles are found as spherical shaped in the size range of 39-78 nm.
