慢性胃炎根据其内镜下表现及病理检查，分为萎缩性胃炎及非萎缩性胃炎，前者作为一种癌前疾病，在预防及筛查早期胃癌中都具有警示意义，应引起消化科医师的重视。笔者从诱因、诊断、高风险人群识别及随访等方面对萎缩性胃炎有关内容进行了简述。.

Single, epitaxial buffer layers of insulating LaMnO3 (LMO) or conductive La0.7Sr0.3MnO3 (LSMO) have been grown by sputter deposition on biaxially textured Ni and Ni–alloy substrates. We report baseline investigations of their compatibility with the Yba2Cu3O7−δ (YBCO) coatings and demonstrate biaxially textured YBCO films grown by pulsed-laser deposition on these single-buffered tapes. Superconducting property characterizations revealed better properties for YBCO films on LMO-buffered tapes relative to those grown on LSMO layers. Self-field critical current densities (Jc) exceeding 1 × 106 A/cm2 at 77 K have been obtained for the YBCO (200 nm) films on LMO-buffer layers. These results offer prospects for the use of single, LMO-buffered metal tapes in the development of practical YBCO-coated conductors.
