简介：[摘要] 目的：观察等离子射频消融术（RFA）治疗早期声门型喉癌的效果。方法：选取本院2020年1月至2022年1月间收治的60例早期声门型喉癌患者，随机分成对照、试验两组：对照组行传统声带切除术，试验组行RFA术。比较手术恢复时间和并发症情况。结果：相较于对照组，试验组手术用时、黏膜恢复时间和住院天数均明显缩短，术后并发症率更低（6.67%vs26.67%），有统计学差异（P＜0.05）。结论：RFA术治疗早期声门型喉癌疗效确切，不仅能加快恢复速度、而且术后并发症少，推荐优先选用。

简介：　　摘要：目的 观察分析 X线在胃底贲门下区癌患者中的诊断效果。方法 选取我院 2017年 3月～ 2019年 3月收治的 40例胃底贲门下区癌患者，全部患者均采用 X线诊断，回顾性分析全部患者临床诊断资料，分析 X线诊断特征和意义。结果 本组 40例胃底贲门下区癌患者中，溃疡型 27例（ 67.50%），龛影周围黏膜变形 27例，不规则钡斑 24例，椭圆形或圆形钡斑 3例，环堤 8例；平坦型 4例（ 10.00%），树根样染钡区和云雾样染钡区各 2例；肿块型 9例（ 22.50%）；溃疡型检出率较肿块型、平坦型明显增高（ P<0.05）。结论 在胃底贲门下区癌患者临床诊断中，行 X线诊断时选择仰卧半立左前斜位，有助于造影诊断，胃底贲门下区癌 X线主要征象为溃疡型，应注意鉴别其与良性溃疡，可提高早期诊断准确率。  　　关键词：胃底贲门下区癌； X线；影像学特征  　　 Abstract: Objective To observe and analyze the effect of X-ray in the diagnosis of cancer in the lower area of gastric fundus and cardia. Methods from March 2017 to March 2019, 40 patients with cancer in the lower gastric fundus and cardia were selected. All patients were diagnosed by X-ray. The clinical diagnosis data of all patients were analyzed retrospectively, and the characteristics and significance of X-ray diagnosis were analyzed. result Among 40 cases of cancer in the lower gastric fundus and cardia, 27 cases were ulcerative type (67.50%), 27 cases were mucosa deformation around niches, 24 cases were irregular barium spots, 3 cases were oval or round barium spots, 8 cases were circular dike; 4 cases were flat type (10.00%), 2 cases were root like barium stained area and 2 cases were cloud like barium stained area; 9 cases were mass type (22.50%); the detection rate of ulcerative type was significantly higher than that of mass type and flat type (P < 0.05). Conclusion in the clinical diagnosis of patients with cancer in the lower gastric fundus and cardia, it is helpful to choose the left anterior oblique position of supine and half vertical position in the X-ray diagnosis. The main X-ray signs of cancer in the lower gastric fundus and cardia are ulcer type. It should be noted to distinguish it from benign ulcer, which can improve the accuracy of early diagnosis.

简介：汉晋南朝东宫侍从官体系中,太子中庶子一直为最高官阶。《汉书·百官公卿表上》未载中庶子为脱漏之故。西汉宣、元、成帝时代,中庶子由太子私属演变为职官,为“亲近之职”,“职如侍中”。晋太子中庶子“受命于天朝”的性质更加清晰,其对太子的谏诤权力更被强化。中庶子“总管门下”,官署称“坊”,具备“侍从左右,傧相威仪”、“尽规献纳”、“奏事文书皆典综之”三种职权。尤其是围绕着典综奏事文书,一方面东宫门下出现机构分化,设置门下通事守舍人、通事舍人等职,另一方面中庶子职权延展出对东宫官僚的监察权。刘宋时太子中庶子由左、右卫将军兼任为常例。这反映了南朝皇权复兴之初对皇位继承的重视。萧梁中庶子的领、兼官没有规律可循,反映中庶子之官职的独立性又重新得到了确立。其原因在于梁武帝晚年皇太子长期监国,依靠东宫门下“文案簿领”的缘故。

简介：如同任何改革都是为了调整关系和利益一样，新一轮课程改革即是调整课程关系，改进教育中两大阵营——教师与学生的关系。教育的对象是学生，课堂上教师的合作伙伴就是学生。教与学，教师与学生，既是矛盾的双方，又是对立的统一体，因此师生的良性互动是一堂课成功的关键。怎样才能引领学生真正发挥主观能动作用，积极参与，主动学习，很大程度上取决于师生之间的关系，取决于教师及所教学科对学生的吸引力，取决于学生对教师及所教学科的热爱程度。

简介：组织好一堂体育课,我认为关键是调动学生的积极性,激发学生学习的兴趣,使体育锻炼成为学生发自内心的需要。这里谈谈自己教学实践中的几点体会:一、教师要注意表率,语言要形象,讲解要生动、精练学生的目光敏锐,模仿能力很强,教师是他

简介：我国政府采购制度推行一年多来，随着各项采购制度的建立、工作的开展及宣传力度的加大，社会各界对政府采购制度有了进一步认识，观念有了很大程度的转变，实行政府采购的意识已逐渐替代了原有自行采购的模式。从目前政府采购情况看，除财政预算安排的采购项目资金外，单位自筹资金委托政府采购的项目金额也越来越多，这充分说明实行政府采购制度体现了公开、公平、公正、择优和效益的政府采购原则，吸引力日趋显著。

简介：《话剧》：您如何看张爱玲、《金锁记》及曹七巧？王：我以为《金锁记》是张爱玲小说中最重要和最好的一部。张爱玲是一个极度个人化的作家，这部小说却是有着强烈的社会批判性，在《金锁记》中，姜府上的人都是绢人儿似的，性格淡漠，内心枯竭，只有曹七巧和姜季泽是饮食男女的人，有着蓬勃的生气与活力，但他们同时又是盲目不知觉的生物．
