Association Between Serum C-Reactive Protein Concentration and Nutritional Status of Malignant Tumor Patients

Background: The level of the systemic inflammatory marker C-reactive protein (CRP) is elevated in many patients with malignant disease and may be related to nutritional status.

Objective: To analyze the association between serum CRP levels in patients with malignant tumors and their nutritional status.

Method: A total of 3,692 cases were analyzed and the serum CRP levels were determined using an immunometric assay. Nutritional status was assessed by using patient-generated subjective global assessment (PG-SGA). The biochemical evaluation of prealbumin (PA), albumin (ALB), cholesterol (CHOL), and triglycerides (TG) were assayed within 48?h admission to the hospital. The association between serum CRP concentration and the nutritional status, the stage of the tumor and other factors was analyzed by univariate and multivariate logistic regression analysis.

Result: Elevated serum CRP was observed in 47.6% (1,548/3,269) of patients compared with the reference value, and the median CRP concentration was 18.29?mg/l. Patient serum CRP concentrations in the malnourished group (PG-SGA B?+?C) were higher than in the well-nourished (PG-SGA A) patients (P?<?0.05). The serum CRP level was related to the patients' age, gender, tumor stage, and was affected by hepatitis, liver cirrhosis, diabetes, but it has no effect on hypertension. The CRP high patients had lower PA and ALB levels, lower Karnofsky performance status scores, and higher PG-SGA scores (P?<?0.05), and there was no relationship with CHOL and TG levels. Weight loss in the previous 1?mo was seen with CRP positive patients (P?<?0.05).

Conclusion: Almost 50% of malignant tumor patients had elevated serum CRP levels indicating a systemic inflammatory state. The nutritional status was worse in cancer patients with higher concentrations of serum CRP. The level of CRP was associated with the tumor stage, and, as stage is a prognostic factor, so can CRP be used as a prognostic maker in malignant tumors patients.     

智慧课堂融合任务驱动教学法在《医学影像学》教学中的应用

目的 探讨智慧课堂融合任务驱动教学法在《医学影像学》教学中的应用效果。方法 选取2018 年9 －12 月大连医科大学2015 级本科临床专业4 个班的学生，分为研究组64 名学生（接受智慧课堂融合任务驱动教学法教学），对照组64 名学生（接受传统授予式教学法教学）。教学结束后，通过随堂测试评价教学效果，内容包括学生客观考核与主观考评。应用SPSS 19.0 软件对数据进行统计分析。结果 研究组学生客观考核成绩（82.39±9.59）高于对照组（70±11.55），差异具有统计学意义（P ＜ 0.05）；研究组学生在激发学习兴趣（82.9% 比10.6%）、培养影像诊断思维能力及阅片技能（91.3% 比5.6%）、培养独立思考与解决问题能力（88.5% 比7.8%）、培养自主学习与科研创新思维（86.7% 比9.2%）均高于对照组学生，具有统计学意义（P ＜ 0.01）；两组学生对智慧课堂融合任务驱动教学法改革的认同感或对教学改革的期待（93.3% 比85.4%）无统计学意义。结论 智慧课堂融合任务驱动教学法，提高《医学影像学》教学质量显著，有助于激发学生的学习兴趣，培养学生的影像学诊断思维模式、良好的阅片习惯及技能。     

lncRNA-LINC00473在胃癌组织中的表达及临床意义

目的:分析LINC00473在胃癌中的表达情况、临床意义及对人胃癌细胞增殖水平的影响。方法:利用癌症基因组图谱(TCGA)数据库下载胃腺癌相关数据集，分析肿瘤组织与正常组织之间LINC00473的表达差异；利用 Kaplan-Meier 曲线进行患者生存分析；MTT方法检测胃癌细胞增殖水平、流式细胞术检测凋亡率的改变。结果:与癌旁组织比较，LINC00473在胃癌组织中的表达明显增加，差异具有统计学意义（P＜0.05）；生存分析发现，LINC00473表达与胃癌患者OS和DFS时间相关，LINC00473高表达的胃癌患者，OS和DFS时间明显缩短（P＜0.05）。转染LINC00473 siRNA至胃癌细胞后，结果发现与阴性质粒转染组比较:转染siRNA-LINC00473的胃癌细胞，LINC00473 表达明显降低；LINC00473表达下调后细胞增殖水平减慢，凋亡率增加。结论:LINC00473是一个新的胃癌生物标记物，可作为潜在的治疗新靶点。     

我国护理学硕士学术学位研究生课程设置调查

目的了解当前我国护理学硕士学术学位研究生课程设置,拟为教育主管部门和护理院校优化课程设置提供参考。方法采用问卷调查法,调查了国内66所护理学硕士学术学位研究生培养院校的课程设置情况。结果护理学硕士学术学位研究生课程类型以公共必修课、专业必修课和选修课为主;66所院校平均设有23.44门课程,护理专业类课程资源不足;课程主要包括思想政治教育、医学专业知识、护理基础理论、研究方法等。院校间学分要求有所差异,64所院校平均总学分为32.07分。结论我国护理学硕士学术学位研究生课程体系逐渐完善,但存在院校间学分要求差异较大,护理专业课程开设不足等问题。各院校需结合自身情况,从调整学分要求、加强护理专业课程建设、减少医学专业课程等方面优化护理学硕士学术学位研究生课程设置;教育主管部门应帮助各院校更加科学地设置护理专业核心课程。
