目的:探讨以器官系统为中心的教学模式应用在消化内科见习教学中的效果和临床教学价值.方法:本研究以齐齐哈尔医学院附属第二医院临床医学专业学生作为研究对象,以2016级作为对照组,以2017级作为实验组,其中对照组采用传统教学模式,实验组采用"以器官系统为中心"的教学模式,对比两组教学效果.结果:实验组理论成绩为(92.46±3.46)分,实践成绩为(94.16±3.88)分,教学满意度评分为(97.24±2.27)分,均高于对照组,组间对比统计学显示具有差异性(P<0.05).结论:以器官系统为中心的教学模式应用在消化内科见习教学中可以提升临床教学效果和教学满意度,值得在临床推广.

"以学科为中心"的医学教育教学模式在长达十几年的实践中虽然获得了良好的发展,但也导致学科间出现了与临床知识脱节、内容重复的问题,越来越无法满足医学教学需求."以器官系统为中心"的教育教学模式可很大程度上弥补传统教育模式的不足,但因为学科专业越分越细,实际应用过程中也面临一些亟需解决的问题.因此,进一步做好"以器官系统为中心"的教学模式的改革工作显得尤为关键,必须予以充分的重视.本文先对现阶段国内医学院"以器官系统为中心"教学模式的应用情况作简要分析,进而提出"以器官系统为中心"教学模式的改革要点与策略.

目的:研究探讨对老年患急性髓系白血病的患者采用地西他滨联合预激方案治疗措施.方法:本次挑选在我院2019年8月至2020年9月期间的患者作为研究对象,选取的患者均已证实为患有急性髓系白血病,共40例患者.根据其入院的时间顺序将分为两组进行对比,各20例.对照组:对患者进行常规传统的治疗方法;观察组:对患者进行采取地西他滨联合预激方案实施.分析讨论其成果疗效.结果:从数据结果得出,观察组的治疗效果是95％,远高于对照组的疗效的70％,其两组之间的比较差异性显著,差异有统计学意义,P＜0.05.结论:本文章探

目的 探讨消化道出血内镜治疗后降钙素原(PCT)和C反应蛋白(CRP)的测定对预防感染及应用抗生素的意义.方法 选取2015年9月～2016年8月我院消化内科收治的消化道出血患者128例,将患者随机分为两组,每组64例.研究组患者接受内镜下治疗并在治疗后使用抗生素预防感染,对照组仅接受内镜治疗.观察两组患者在内镜治疗前1天、治疗后第1天、第7天的PCT与CRP水平,并记录患者的不良反应发生情况和治疗效果.结果 两组患者治疗前PCT与CRP水平接近(P＞0.05),治疗后研究组的PCT和CRP水平分别为(0.97±0.23) ng/mL、(7.24±2.48)ng/mL,均明显低于对照组(P＜0.05).研究组不良反应发生率少于对照组(P＜0.05);研究组在治疗效果方面显著优于对照组(P＜0.05).结论 对消化道出血患者采用内镜治疗后使用抗生素效果显著,有助于患者的康复.

Objective:To investigate the effects of long-term treatment with nucleoside antiviral drugs on hepatic hemodynamics and serum Th1/Th2 level in patients with hepatitis B.Methods: 76 cases of hepatitis B patients admitted to our hospital from January 2015 to December 2015 were selected as the research objects. According to the treatment of patients with program divided into control group and observation group, control group (35 cases) patients received routine hepatitis B clinical treatment, but not taking nucleotide analogues, and observation group (41 cases) of patients in the conventional treatment based on long-term oral nucleotide antiviral drugs were compared between the two groups before and after treatment in patients with liver hemodynamics and serum Th1/Th2 helper T lymphocyte, T1/T helper 2 type cytokines level changes.Results: The PVV, PVD, PVCL, HV-DI, HAAT, HV-HA index of two groups of patients before treatment, showed no significant difference, but after treatment were significantly improved. However, the effect of the observation is more significant and the differences were statistically significant (t=1.253, t=0.925,t=0.413,t=0.816,t=2.931,t=2.517,t=2.915;P<0.05). The IL-4, IL-6, IFN-gamma, TBil and other indicators of two groups of patients before treatment, were no significant differences, but after treatment, the indexes were significantly improved. The indicators in the treatment group were improved more significantly. The differences were statistically significant (t=1.957,t=1.681,t=2.041,t=2.113;P<0.05).Conclusion: The long-term nucleotide antiviral drugs in the treatment of chronic hepatitis B can effectively improve the indicators of liver hemodynamics, improve the serum level of cytokines in patients. It plays an important role in improving the liver function, balancing the cirrhosis cytokines network with hepatitis B patients, and regulating immune function.

目的 探究双歧四联活菌片结合氟康唑在治疗真菌性肠炎中的应用价值. 方法 我科选择收治的真菌性肠炎患者90例,随机分成结合组和对照组,使用双歧四联活菌片结合氟康唑治疗,观察其治疗后的效果,并进行统计和分析对比. 结果 结合组共有42(32+10)例患者治疗有效,其有效率为93. 33%;对照组共有35(19+16)例患者治疗有效,其有效率为77.78%,两组结果差异性显著,具有统计学意义(P<0.05). 结论 应用双歧四联活菌片结合氟康唑治疗真菌性肠炎效果显著,明显优于只使用氟康唑,其可以有效的抑制和抵抗真菌繁殖,具有显著的疗效,值得在临床推广.
