Effect of electroacupuncture at Ximen (PC 4) and Hegu (LI 4) on expression of Akt in rats with myocardial ischemia-reperfusion injury.

Objective: To investigate the effect of electroacupuncture (EA) at acupoints on the pericardium meridian on the expression of phosphorylated Akt (p-Akt) protein in rat myocardium after ischemia and reperfusion.

Methods: Seventy Wistar rats were evenly randomized into seven groups: the sham operation group (group A), ischemia-reperfusion model Ⅰ group (group B), ischemia-reperfusion model Ⅱ group (group C), EA at Neiguan (PC 6) group (group D), EA at Ximen (PC 4) group (group E), EA at Hegu (LI 4) group (group F), and LY294002 + EA at Neiguan (PC 6) group (group G). All processes were monitored by electrocardiography.

Photodecolorization of Rhodamine B on tungsten-doped TiO2/activated carbon under visible-light irradiation.

Tungsten-doped TiO(2)/activated carbon catalysts have been prepared by a supercritical-pretreatment-assisted sol-gel process. The structural features of the photocatalysts have been investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV/Vis diffuse-reflectance spectroscopy (DRS), electron dispersive X-ray (EDX), photoluminescence spectroscopy, and Brunauer-Emmett-Teller (BET) analysis. The results revealed that a W-TiO(2) layer was coated on the AC surface, and had higher surface area and smaller crystallite size than TiO(2)/AC obtained by a similar route.

[Effects of herbal cake-separated moxibustion on the expression of erythrocyte CD58 in different ages of healthy people].

Objective: To observe the efficacy of herbal cake-separated moxibustion on the expression of erythrocyte CD58 in different ages of healthy people and explore the differences of the therapeutic effect in different ages and its mechanism.

Methods: A total of 82 health participants were divided into a young age group and a middle-old age group according to the ages. They were treated with herbal cake-separated moxibustion on Shenque (CV 8), Guanyuan (CV 4), Zusanli (ST 36), Pishu (BL 20), Shenshu (BL 23) with cake made by Shudihuang (Radiz Re hmanniae Preparata), Shanyao (Rhizoma Dioscoreae), Shanzhuyu (Fructus Corni ), etc.

Activated carbon supported TiO2-photocatalysis doped with Fe ions for continuous treatment of dye wastewater in a dynamic reactor.

Fe-doped TiO2 coated on activated carbon (Fe-TiO2/AC, FTA) composites were prepared by an improved sol-gel method and characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffractometry, inductively coupled plasma mass spectrometry and BET surface area analysis. Obtained FTA composites were applied to the continuous treatment of dye wastewater in a dynamic reactor. The effects of Fe ion content, catalyst content, UV-lamp power and flowrate of the continuous treatment of dye wastewater on degradation efficiency were analyzed to determine the optimum operating conditions of dye wastewater degradation.

[Effects of acupuncture at the points of the Pericardium Meridian on the activity of myocardial Ca2+-ATPase and gene expression in the rat of myocardial ischemia and reperfusion injury].

Objective: To investigate the mechanism of acupuncture at "Neiguan" (PC 6) and "Ximen" (PC 4) of the Pericardium Meridian in treatment of myocardial ischemia.

Methods: Rats were randomly divided into 5 groups, sham-operation group, ischemia-reperfusion model group, Neiguan acupuncture group, Ximen acupuncture group and Zhigou acupuncture group. Electroacupuncture (EA) was given at corresponding acupoints for 20 min in the later 3 groups, followed by ligation of the left anterior descending branch of the coronary artery and 40 min later, acupuncture was given at the points for another 20 min, reperfusion for 60 min, with ECG monitoring.
