Reciprocal Peer Support for Post-partum Patients with Diabetes: A Needs Assessment for the Diabetes Buddy Program

While peer support has been investigated in multiple clinical contexts, its application to the postpartum setting is unknown. The aim was to assess acceptability of a postpartum peer support program for women with diabetes. Observational survey-based needs assessment of forty low-income women with diabetes, receiving care at a major medical institution. Mean age and gravidity were 30.7 years and 3.15 ± 1.67 respectively. 45 % expressed interest in a “buddy.” There was no significant difference between groups desiring and not desiring this program. A majority of respondents desired telephone, text messaging, and in-person contacts (79.2, 72.1, 83.8 %), with 72.5 % of patients desiring diabetes-related activities during clinic waiting time. Many women desire a postpartum diabetes reciprocal peer program for support outside of clinician visits. Patients are receptive to educational services during their wait and outside of clinic time, a potentially valuable opportunity to share important health information.     

MRI图像融合技术在肛瘘评估中的初步应用

目的采用图像融合技术获得T2WI与T2WI-FS的融合图像，评估其在肛瘘及肛周结构显示中的优势。 方法2016年6月至2018年6月，前瞻性选择中山大学附属第一医院29例肛瘘患者进行肛管磁共振（MR）检查，采用图像融合技术获取T2WI与T2WI-FS的融合图像T2WI-Fusion，利用Fisher score算法计算瘘管及肛门括约肌的组织间分辨力Fisher值、脂肪与肛门括约肌间的Fisher值，评估融合图像中瘘管及肛周结构的显示情况。采用改进的双刺激连续质量量表（DSCQS）对T2WI-FS、T2WI、增强3D-VIBE和T2WI-Fusion序列图像进行主观图像质量评价。 结果29例患者均成功获得T2WI与T2WI-FS的融合图像T2WI-Fusion。T2WI-Fusion、T2WI瘘管与括约肌间Fisher均值分别为6.46、3.31，T2WI-Fusion图像对瘘管的显示优于T2WI序列图像（P<0.001）。T2WI-Fusion、T2WI-FS脂肪与括约肌间Fisher均值分别为10.61、2.45，T2WI-Fusion图像对括约肌的显示优于T2WI-FS序列图像（P<0.001）。T2WI-Fusion对瘘管与括约肌的图像质量评价总评分均高于T2WI-FS、T2WI、增强3D-VIBE序列（P<0.001）。 结论MRI图像融合技术同时具备T2WI及T2WI-FS的优势，无需增加扫描序列及扫描时间，且操作简单，花费时间短，显著提高病变及肛周解剖结构的对比度和图像质量。     

刺果甘草全基因组Survey及叶绿体基因组特征分析＊

目的 基于基因组Survey分析对刺果甘草Glycyrrhiza pallidiflora Maxim.基因组大小和杂合率进行估计，并通过叶绿体基因组序列特征对其在甘草属Glycyrrhiza L.中的系统发育位置进行研究。方法 使用二代测序技术对刺果甘草进行测序，采用K-mer方法对测序reads进行分析，估算刺果甘草基因组大小和杂合率，使用生物信息学方法进行叶绿体基因组组装、注释和系统发育分析。结果 Survey分析结果显示其基因组大小约为577.82 Mb，杂合度约为0.31%，重复序列比例约为53.72%。叶绿体基因组长度为127，267 bp，不具有典型的四分体结构，总GC含量为34.32%，包含110个基因，其中76个蛋白质编码基因，30个tRNA基因和4个rRNA基因。系统发育分析表明，刺果甘草与圆果甘草G. squamulosa Franch.亲缘较接近。结论 刺果甘草存在低杂合和重复序列较多的特点，为了更好地对全基因组进行序列拼接和组装，可尝试采用三代测序结合二代测序的分析策略进行基因组组装；刺果甘草叶绿体全基因组比对和系统发育分析，为后续开展甘草属遗传多样性研究和分子鉴定标记筛选提供了重要依据。     

主动脉窦瘤破裂的外科治疗体会

目的：总结主动脉窦瘤破裂的手术适应症、手术方法和预后。方法：回顾性分析2011年1月至2017年12月因主动脉窦瘤破裂于我院行外科手术治疗的130名患者资料。其中男性58例(44.62%)，女性72例(55.38%)，年龄32～75（52.72±13.87）岁。合并室间隔缺损55例(42.31%)，合并主动脉瓣关闭不全39例(30%)，合并房间隔缺损12例(9.23%)，合并三尖瓣关闭不全8例(6.15%)，合并二尖瓣关闭不全6例(4.62%)，合并主动脉夹层1例(0.77%)，合并其他心脏疾病9例(6.92%)；破裂开口起源于右冠窦119例，起源于无冠窦11例。所有患者均在中低温体外循环下行手术治疗。结果：所有患者中，2例患者围术期死亡，余128例患者随访5个月至5年，术后心功能恢复至I-II级。结论：一旦发现主动脉窦瘤破裂，应积极予以治疗。     

灾后救灾干部心理重建研究进展

灾后心理重建工作越来越受到人们的重视,目前已经被正式纳入灾后重建体系。近年来研究表明,灾后救灾干部心理健康水平低于正常人,存在不同程度的生理和心理健康问题,而且与多种影响因素有关。灾后心理重建包括物质干预和心理干预等措施。现就灾后救灾干部心理重建研究进行综述。     

不同营养状况与慢性阻塞性肺病患者预后的相关性分析

<正>慢性阻塞性肺病(chronic obstructive pulmonary diseases,COPD)在临床呼吸科发病率与病死率排名首位,使患者的生命受到严重威胁[1]。COPD患者由于消化、呼吸功衰退,营养吸收功能减弱,同时气道阻力升高,减弱了肺部顺应性,所以伴发能量不足型营养障碍的机率较高[2-3]。出现营养不良的患者往往疾病加重,影响预后,而临床COPD患者疾病严重程度与预后又同肺功能变化密切相关[4]。本文分析了不同营养状况与COPD患者预后的相关性。     

Cardiovascular effects and mechanisms of sodium-glucose cotransporter-2 inhibitors

Sodium-glucose cotransporter-2 inhibitors (SGLT2 inhibitors) are a new type of drug for the treatment of diabetes, and they have been proven to have a good hypoglycemic effect. Several lines of clinical evidence have shown that SGLT2 inhibitors can significantly reduce the risks of atherosclerosis, hospitalization for heart failure, cardiovascular death, and all-cause mortality and delay the progression of chronic kidney disease. Because of the protective effects of SGLT2 inhibitors on the heart and kidney, they are being studied for the treatment of heart failure and chronic kidney disease in patients without diabetes. Therefore, it is necessary for cardiologists, patients with diabetes, and nephrologists to fully understand this type of drug. In this review, we summarize the following three aspects of SGLT2 inhibitors: the recent clinical evidence of their cardiovascular benefits, their mechanisms of action, and their safety.
