Effects of Nitrogen Content on the Structure and Mechanical Properties of (AlCrFeNiTi)N High-Entropy Films by Reactive Sputtering.

In this study, (AlCrFeNiTi)N high-entropy films are prepared by a reactive direct current (DC) magnetron sputtering at different N flow rates on silicon wafers. It is found that the structure of (AlCrFeNiTi)N high-entropy films is amorphous, with x = 0. It transforms from amorphous to a face-centered-cubic (FCC) structure with the increase of nitrogen content, while the bulk AlCrFeNiTi counterpart prepared by casting features a body-centered-cubic (BCC) phase structure.

[Expressions of HSP 70 and NF-kappaB in the peripheral blood lymphocyte of chronic gastritis patients of different syndrome patterns].

Objective: To study the expressions of heat shock protein 70 (HSP 70) and nuclear factor-kappa B (NF-kappaB) in the peripheral blood lymphocyte of chronic gastritis (CG) patients of Pi-Wei hygropyrexia syndrome (PWHS) and Pi-qi deficiency syndrome (PQDS), and to explore their correlation with Helicobacter pylori (Hp) infection.

Methods: Recruited were totally 86 CG patients who visited at the clinics of gastroenterology, First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, including 67 patients of PWHS (30 of predominant-dampness, 30 of equal dampness and heat, and 30 of predominant-heat) and 19 patients of PQDS. Another 12 volunteers from healthy employees and students of Guangzhou University of Traditional Chinese Medicine were recruited as the control group.
