高龄产妇产后抑郁影响因素的质性研究

目的 探究高龄产妇产后抑郁的影响因素，为护理人员今后在临床工作中提供个性化的护理服务提供参考依据。方法 采用质性研究中的现象学研究法对2021年12月至2022年4月在内蒙古医科大学附属医院妇产科建档分娩的16例高龄产妇进行半结构式访谈，并以Colaizzi现象学研究方法进行资料分析。结果 提炼出影响高龄产妇产后抑郁的4个主题：躯体性压力源；负性心理体验；社会支持缺乏，矛盾出现；角色转变对高龄产妇的影响。结论 需重视高龄产妇产后的主观感受，加强产前产后健康宣教，构建以家庭为中心的高龄产妇产后护理模型，减少产后抑郁的发生。     

A systematic review of antiglycation medicinal plants

Background and objectivesThe present review shows a list of anti-glycation plants with their anti-glycation activity mechanisms that can attract the attention of pharmacologist for further scientific research towards finding better remedy for diabetic complications.MaterialsGoogle scholar, Pubmed, Web of Science and Scopus were searched. The terms were advanced glycation end products (AGEs), medicinal plants, antiglycation products.Resultsplants that studied in this review inhibit glycation in several possible mechanisms. Some of these plants inhibit the production of shiff base and amadori products. The others inhibit the generation of amadori products in the advanced phase. Some others blocked the aggregation of AGEs and some plants have antioxidant activity and reduce AGEs formation by preventing oxidation of amadori product and metal-catalyzed glucoxidation.ConclusionThis review can help pharmacologist to find antiglycation natural substance that can be useful in treatment of diabetic complications.     

阿帕替尼治疗晚期及术后复发肺肉瘤样癌的疗效分析

目的探索阿帕替尼治疗晚期及术后复发肺肉瘤样癌的疗效。方法收集2016年6月至2019年8月Ⅲ~Ⅳ期及术后复发的肺肉瘤样癌患者21例,口服阿帕替尼(250~425 mg/d)治疗,30 d为1个疗程,观察并分析疗效及评价安全性。结果21例患者中,完全缓解(CR)为0,部分缓解(PR)为14.3%(3例),稳定(SD)为33.3%(7例),疾病进展(PD)为52.4%(11例);客观反应率(ORR)为13.3%(3例),疾病控制率(DCR)为47.6%(10例)。中位总生存期(mOS)为4.6个月,中位无进展生存期(mPFS)为1.0个月。病灶≥6 cm(或≥5 cm)较<6 cm(或<5 cm)平均OS明显缩短,差异有统计学意义(P<0.05);术后分期Ⅰ~Ⅱ期较Ⅲ~Ⅳ期平均OS明显延长(P<0.05)。位于中央的病灶较周围的病灶平均OS明显缩短,差异有统计学意义(P<0.01)。性别、年龄(>60岁,≤60岁)、吸烟史(是/否)对疗效影响差异无统计学意义。常见不良反应包括高血压38.1%(8例)、蛋白尿23.8%(5例)、手足综合征28.6%(6例)、腹泻28.6(6例)、骨髓抑制38.1%(8例)。结论阿帕替尼治疗晚期及术后复发肺肉瘤样癌具有一定疗效,不良反应可控,病灶大小、位置及分期可能是疗效的独立影响因素。     

我国血吸虫对吡喹酮抗药性研究之概要

血吸虫病是一种严重危害人类健康、影响社会经济发展的重大传染病,为全球公共卫生负担和危害最严重的被忽视的热带病之一。吡喹酮是20世纪70年代研制出的一种高效、低毒、价廉的广谱抗蠕虫口服药,为世界卫生组织（WHO）推荐的抗血吸虫的首选药物。吡喹酮在血吸虫病流行区现场大规模反复使用已超过40年,血吸虫是否会对吡喹酮产生抗药性引起国际社会极大担忧,为学术界关注的热点科学问题。针对血吸虫病防治中这一重大需求,自1996年起, 在国家科技支撑计划、国家自然科学基金、江苏省自然科学基金等项目基金资助下,我们在血吸虫病流行区现场和实验室,对血吸虫在吡喹酮药物的压力是否会产生抗药性、抗性虫株的生物学特性、抗性的检测、吡喹酮抗性的交叉抗药性及抗药性的预防和控制等科学问题进行较为系统的研究,本文就其研究及其意义作一概述。     

探究培美曲塞与多西他赛在晚期非小细胞肺癌靶向治疗失败后挽救化疗中的临床疗效

目的 研究培美曲塞与多西他赛在晚期非小细胞肺癌靶向治疗失败后挽救化疗中的应用效果。方法 筛选2018 年1 月～2020 年1 月本院的60 例晚期非小细胞肺癌靶向治疗失败后挽救化疗的患者作为研究对象，依据患者选择的药物种类分为观察组和对照组，每组各30 例，对照组采用多西他赛治疗，观察组予以培美曲塞治疗，对比分析两组的近期治疗效果、生存质量评分和毒副反应发生情况。结果 观察组病症控制率为66.67%，对照组病症控制率为36.67%，观察组病症控制效果更好；观察组生存质量评分为（65.2±3.4）分，对照组生存质量评分为（51.7±4.6）分，两组比较差异有统计学意义（t=12.926，P=0.000）；观察组各项毒副反应发生率均低于对照组，差异有统计学意义（P＜0.05）。结论 在晚期非小细胞肺癌靶向治疗失败后进行挽救化疗中选用培美曲塞有更好的治疗效果，可以较好的进行临床治疗，改善患者的生活质量，且产生的毒副反应较少，在实际临床中的应用价值较高。     

HER2-positive advanced breast cancer treatment in 2020

HER2-positive breast cancer is an aggressive subtype identified in the 1980s. The development of therapies targeting the HER2 has improved outcomes. The current standard of care, established in 2012 is dual blockade with trastuzumab + pertuzumab as first-line followed by TDM-1 as second-line. Several suboptimal choices are available in third-line or more. In 2019 the presentation of several trials evaluating new drugs and regimens in third-line has re-opened questions about sequencing, treatment of triple positive disease and treatment choice after exposure to TDM-1. These include tucatinib, neratinib and trastuzumab-deruxtecan. Other agents – including other antibody drug conjugates and bispecific antibodies as well as combinations - will lead to further changes in coming years. Additionally, should the numerous putative biomarkers thus identified ever come into use at the clinic, choice of treatment and response evaluation may be substantially changed.
