Constructing queer mother‐knowledge and negotiating medical authority in online lesbian pregnancy journals

Medical interactions around reproduction are increasingly extending beyond the physician's office and onto the Internet, where negotiation with medical authority occurs in complex and dynamic ways. Recently, scholars have noted the Internet's potential for creating spaces where women can dialogue with and reconstruct medical authority, yet this growing body of work is overwhelming heteronormative. This paper thus interrogates how lesbian women use the Internet to challenge, deploy, and rework medical authority around reproduction while navigating the transition to parenthood. I draw from 17 online journals authored by lesbian couples during the conception, pregnancy, and birth of their first child, each spanning between 18 months and 2 years, in order to understand how the transition process unfolds over time. I argue that lesbian couples engage with medical authority when seeking affirmation and normalisation yet discard and publicly reject the heteronormative assumptions that accompany reproductive medicine. Further, they chart a new process that I term ‘constructing queer mother‐knowledge’, in which they critique and balance knowledges from institutionalised medicine, their own bodies, and their queer communities. With this new concept, I complicate understandings of lesbian mothers‐to‐be and their interactions with medical authority as they build subversive families.     

Valuing height: diagnosis,valuation and the case of idiopathic short stature

This paper proposes a ‘valuographic’ approach to diagnosis, exploring how values and valuation practices are implicated in the contested diagnostic category of idiopathic short stature (ISS). ISS describes children who are ‘abnormally’ short but do not have any other detectable pathology. In the USA growth‐promoting hormone therapy has been approved for ISS children, since 2003. However, no other jurisdiction has approved this treatment and the value of ISS as a diagnostic category remains disputed among healthcare professionals. Drawing on qualitative interviews with paediatric endocrinologists in the UK and the US, this study presents a historical snapshot illustrating how the problematisation of ISS as a diagnosis involved multiple registers of value including epistemic, economic and moral calculations of worth. Contestation of the diagnosis was not just about what counts but about what ought to be counted, as respondents’ accounts of ISS gave differential weight to a range of types of evidence and methods of assessment. Ultimately what was at stake was not just the value of increased height for short patients, but what it meant to properly practice paediatric endocrinology. Consideration is then given to how a valuographic approach can be applied to sociological studies of diagnosis more broadly.     

嗜肺军团菌致病性与效应蛋白的研究进展

嗜肺军团菌是一种可以引起军团菌肺炎和庞蒂亚克热的兼性胞内病原菌，主要侵染阿米巴原虫和人类巨噬细胞。该菌在宿主胞内能依靠Dot/Icm IVB型分泌系统产生的效应蛋白成功逃避溶酶体的降解。本文主要对嗜肺军团菌的致病物质、胞内存活与增殖机制及其效应蛋白的生物学功能进行综述，详细介绍嗜肺军团菌的毒力因子与致病机制，为军团病防治的研究提供新思路，也为其他胞内病原菌所致感染性疾病的研究提供重要的借鉴意义。     

Measuring catastrophic medical expenditures: Reflections on three issues

In the “basic” approach, medical expenses are catastrophic if they exceed a prespecified percentage of consumption or income; the approach tells us if expenses cause a large percentage reduction in living standards. The ability‐to‐pay (ATP) approach defines expenses as catastrophic if they exceed a prespecified percentage of consumption less expenses on nonmedical necessities or an allowance for them. The paper argues that the ATP approach does not tell us whether expenses are large enough to undermine a household's ability to purchase nonmedical necessities. The paper compares the income‐based and consumption‐based variants of the basic approach, and shows that if the individual is a borrower after a health shock, the income‐based ratio will exceed the consumption‐based ratio, and both will exceed the more theoretically correct Flores et al. ratio; whereas if the individual continues to be a saver after a health shock, the ordering is reversed and the income‐based ratio may not overestimate Flores et al.'s ratio. Last, the paper proposes a lifetime money metric utility (LMMU) approach defining medical expenses as catastrophic in terms of their lifetime consequences. Under certain assumptions, the LMMU and Flores et al. approaches are identical, and neither requires data on how households finance their medical expenses.     

序贯培养体系和单一培养体系对人卵母细胞受精和早期胚胎发育的影响

目的：比较在体外受精/卵胞质内单精子显微注射（IVF/ICSI）治疗周期中序贯培养体系和单一培养体系对人类早期胚胎发育的影响，为人类辅助生殖技术中胚胎培养体系的选择和评估提供参考。方法：选取155例行IVF/ICSI助孕的患者，将同一个患者的卵子分为2组，分别在Vitrolife的序贯培养体系G-IVF/G1/G2培养液（序贯培养组）和Irvine的单一培养体系CSCC培养液（单一培养组）中进行体外受精和胚胎培养，观察2组不同培养体系中胚胎受精和胚胎早期发育情况。结果：与单一培养组比较，序贯培养组受精率、双原核（2PN）受精率和多核受精率差异均无统计学意义（P>0.05）。在IVF患者中，序贯培养组和单一培养组的卵裂率、可用胚胎率、优质胚胎率和囊胚形成率比较差异均无统计学意义（P>0.05）；在ICSI患者中，序贯培养组和单一培养组的卵裂率、可用胚胎率和囊胚形成率比较差异均无统计学意义（P>0.05），但序贯培养组优质胚胎率明显高于单一培养组（P=0.015）。在IVF和ICSI患者中，单一培养组第3天胚胎致密化的比例均明显高于序贯培养组（P=0.001）。在序贯培养组中胚胎形态表面光滑均匀，单一培养组中胚胎表面较为粗糙且有颗粒状。结论：G-IVF/G1/G2序贯培养体系和CSCC单一培养体系对人卵母细胞受精和早期胚胎发育的影响无明显差异。     

PBL联合CBL教学法在中医院校影像教学中应用的优势

随着影像技术的快速发展,影像检查已发展为临床诊断疾病的主要手段之一。所以作为未来医疗工作者的医学生,学好影像学变得越来越重要。目前影像教学大多采用传统的“满堂灌”的授课方式,学生处于学习的被动状态,效果并不尽人意。如何才能让学生真正掌握影像学知识,是值得每位任教老师深思的问题。作者结合多年的教学经验与实践,并针对中医院校医学生西医知识相对薄弱,课时少这一特点,认为PBL联合CBL教学法不但可以激发学生学习的主观能动性,培养学生的自学能力,增强学生解决问题的能力,提升临床思维能力,还可以提高课堂效率,有利于学生更好地学习、掌握影像知识,并学会将所学理论知识应用于临床实践。     

妇产科住院医师临床技能培训体系构建

妇产科学是一门涉及面广、实践性和操作性均很强的学科,对医生临床操作能力的要求也格外严格。妇产科住院医师临床技能操作水平的高低是评价其岗位胜任力的重要指标,开展全面、规范的临床技能培训,有利于切实提高其临床操作能力,是培养合格妇产科专科医师的必经途径。研究以南京医科大学附属妇产医院为例,讲述了该院从目标体系、过程管理体系、考核评价体系和质量控制体系4个方面出发,探索构建适合专科医院特色的妇产科住院医师临床技能培训体系,并在实践过程中不断完善该体系,以期不断提升妇产科住院医师的临床工作能力,有效增强其岗位胜任力和综合素质。     

“混合式教学+医学教育”实现教学评价研究

教学评价是教学过程中不可或缺的,行之有效的教学评价是促进教学方法改革,增强教学效果的指挥棒。与传统的教学方法相比较在混合式医学教学课堂中,教学评价也应进行相应的改革,从教师、自身、同行三个维度研究混合式医学教学中的教学评价方法的改革。同时强调完善教学评价的反馈机制。通过学生反馈、专家反馈、同行反馈、自身反馈,建立完整的混合式教学+医学教育的教学评价体系。
