健康教育在白血病护理中的应用效果

目的评价血液科白血病疾病护理中应用健康教育的临床效果,为白血病护理工作提供参考。方法选择医院收治的白血病患者,总计60例。进行白血病患者随机分组护理,对照组与试验组各30例白血病患者,分别采取常规护理和常规护理+健康教育,比较2组白血病患者的负性情绪、自我效能状况评分以及护理满意度、护理依从率。结果试验组白血病患者干预后SAS、SDS、GSES评分均明显优于对照组,护理满意度与护理依从率均明显高于对照组,指标差异具有统计学意义,P>0.05。结论血液科白血病治疗期间配合落实常规护理、健康教育可以在提高患者自我效能的同时提高患者的依从性,符合患者身心护理需求,整体护理效果显著。     

The impact of frost-damage on the quality and quantity of the secreted antigen-specific IgG repertoire

Freezing of alum-based vaccines drastically alters their colloidal composition and leads to irreversible cluster formation. The loss of stability is well described, but the impact of frost damage on the functionality of the induced and secreted antibody repertoire has not been studied in detail. We therefore applied our single-cell measurement platform to extract the frequencies of Immunoglobulin G-secreting cells in combination with individual secretion rates and affinities. We showed that, frost-damaged or not, the tested vaccine was able to generate similar frequencies of total and antigen-affine IgG-secreting cells. Additionally, the frost-damaged vaccine stimulated a similar T-cell cytokine secretion pattern when compared to the regularly stored vaccine. However, frost-damaged vaccines induced no efficient affinity maturation and a complete collapse of the affinity distribution was observed. This study unveiled the impact of frost-damage to alum-based vaccines on the induced secreted antibody repertoire, and illustrated the power of functional single-antibody analysis.     

PBL教学法在核医学课间实习教学中的应用研究

目的 通过与LBL教学法对比,探讨PBL教学法在核医学科课间实习教学中的应用效果.方法 选取哈尔滨医科大学2016级临床医学专业本科二班学生72人,随机分为实验组和对照组,每组各36人,在课间实习教学中分别实施PBL教学法和LBL教学法.实习结束后,通过考试及问卷调查,进行教学法评价.结果 观察组在考试成绩、学习兴趣、学习热情、教学满意度、培养临床思维、增强知识点掌握等教学法评价指标均优于对照组,具有统计学意义(P<0.05).结论 与LBL教学法相比,PBL教学法应用于核医学科课间实习教学中更能激发学生学习兴趣、增强综合素质,从而提高教学效果.     

白细胞介素35和白细胞介素37与结直肠癌临床病理学特征及预后的相关性研究

背景与目的：结直肠癌（colorectal cancer，CRC）为世界第三常见恶性肿瘤，近年来研究者认为白细胞介素（interleukin，IL）-35和（或）IL-37与CRC的发展有关，但其作用机制尚未阐明。探究IL-35和IL-37在CRC发展中的作用及其可能的机制，分析IL-35和IL-37与CRC患者预后的相关性。方法：收集2013年—2017年在上海交通大学医学院附属同仁医院接受治疗的191例CRC患者手术病理蜡块的肿瘤组织，与其匹配的非癌组织是来源于同一患者的肠癌手术切缘蜡块组织。应用免疫组织化学（immunohistochemistry，IHC）染色法将CRC患者的癌组织与非癌组织染色，并运用Image-Pro Plus将IHC染色阳性部分定量分析，结合随访结果，探讨癌组织与非癌组织中IL-35和IL-37的表达水平与CRC临床病理学特征及预后的相关性。结果：与非癌组织相比，CRC组织中IL-35的表达量减少了50%（P<0.000 1）。CRC组织中IL-37的表达量与非癌组织相比增加了40%（P=0.012）。多因素生存分析显示，癌组织中IL-35（HR=0.39；95% CI：0.16~0.97；P=0.04）的表达水平是CRC患者术后生存的独立预测指标。结论：IL-35和IL-37蛋白的表达水平可能与CRC的发展有关，IL-35的表达水平可能是CRC患者术后生存的独立预测指标。     

Recurrent respiratory papillomatosis in northern Sweden: Clinical characteristics and practical guidance

Conclusion: Recurrent respiratory papillomatosis (RRP) patients with high surgical treatment frequency (≥ 1/year, HF) were significantly younger and had a more widespread laryngeal disease compared to a low frequency treated group (< 1 treatment/year, LF). This study confirms the existence of a clinical RRP group, not primarily related to HPV sub-type, but more care-intensive and in need of more vigilant follow-up. Objectives: RRP is associated with high morbidity due to its influence on breathing and voice. The purpose of this study was to characterize RRP patients in northern Sweden and investigate possible predictor factors affecting therapeutic needs. Method: Patients from the regional referral area (northern Sweden) were categorized for age, disease duration, juvenile or adult onset, profile of disease development, number of surgical sessions in relation to disease duration, laryngeal deposition of papilloma, gender, and HPV sub-types, in order to identify patients with increased need for frequent surgical treatment. Results: The median age of the RRP patients (n = 48) was 44.5 years; 34 (71%) were males and 14 (29%) females, most were infected with HPV 6. Patients with high surgical treatment frequency/year were significantly younger and showed more widespread papillomatous vegetation in the larynx, compared to the low frequency treated group.
