Methods The study group comprised 72 patients with hypercholesterolemia. the control group comprised 30 healthy volunteers.

入选高胆固醇血症患者72例，同时选取健康志愿者30例作为正常对照组。

Methods: Add different power spherical lenses on 32 volunteers with normal binocular function to induce simple myopia(+1D,+2D,+3D),simple hypermetropia(-1D,-2D,-3D) and anisometropia.Assess the visual acuity,stereocontrast sensitivity and Worth 4 dots fusional function after inducing the anisometropia.

对双眼视功能正常的大学生志愿者32人采用在单眼前加不同度数正负球镜的方法，诱导单纯近视性(+1D，+2D，+3D)及单纯远视性(-1D，-2D，-3D)屈光参差，测定诱导屈光参差后的视力、立体视敏度及Worth四点融像功能。

Methods With hypotonia and water filling, the stomach of 10 normal volunteers and 35 cases of gastric carcinoma diagnosed by biopsy underwent pre-contrast and dynamic contrast enhanced MR scans. The imaging findings and tumor staging were blindly and independently assessed by two radiologists, and the imaging findings were correlated with the pathologic results.

方法通过采用低张、水充盈技术，对10例健康成人志愿者和35例临床经胃镜活检确诊为胃癌患者行MR平扫及动态增强扫描，结果采用双盲法阅片，并与手术病理结果进行对照，对所有MRI分期与病理分期进行Kappa一致性检验。
