The Transmission of Trauma from Mother to Infant: Radioactive Residues and Counter-Transference in the Case of a Haitian Mother and Her Two-Year-Old Son*

ABSTRACT

Close observation of the interactions between a traumatised mother and her infant son provides information on the modes of transmission of psychic trauma in the mother–infant dyad. Following the presentation of a current literature review on the theme, the subject of “radioactive residue” and counter-transference in the transmission of psychic trauma from mother to infant will be illustrated through a clinical case study that focuses on a Haitian mother and her two-year-old infant son who has been referred to a “transitional care nursery” in urban Paris. The encounter with this mother–infant dyad is analysed through observing the quality of the interactions that take place between the mother and infant in order to determine how a particularly traumatic narrative impacts the mother–infant relationship, in addition to relations with the clinician. Mother and infant respond to one another through the emission and reception of “radioactive residues” as hypothesized by Gampel. This clinical case study shows that there is a need to consider transcultural factors and collective experience and history when analysing traumatic events. Additionally, the case study shows that counter-transference can be an effective clinical tool for gaining access to an infant's experience as the recipient of a traumatic narrative.     

乙肝孕妇血清标志物模式与HBV-DNA载量及肝功能关系研究

目的探讨乙肝孕妇血清标志物模式、HBV-DNA载量及肝功能三者之间的关系,为孕期乙肝病毒感染情况的监控和乙肝病毒母婴传播的预防提供参考。方法选取2019年1月-11月在我院产检的767例乙肝表面抗原阳性孕妇的乙肝血清标志物模式、肝功能指标的丙氨酸氨基转移酶(alamine aminotransferase,ALT)及HBVDNA载量进行研究,探讨三者间的关系。结果HBsAg、HBeAg、HBcAb阳性组孕妇HBV-DNA阳性率及病毒载量均高于其余两组(P<0.05);ALT升高程度与HBV-DNA载量具有一定相关性(r=0.255,χ^2=80.150,P=0.000);HBeAg阳性组和HBeAg阴性组间HBV-DNA阳性率、ALT异常率差异均有统计学意义。结论HBV-M、HBV-DNA与肝功能之间有一定的相关性,大三阳孕妇中高病毒载量比例高,应加强乙肝孕妇孕期各项指标的监测,必要时进行干预治疗。     

佛山市乙型肝炎母婴阻断工作环节问题探讨

目的探讨佛山市乙肝母婴阻断工作中存在的问题，为完善进一步工作提供思路。 方法采用队列研究的方法，以2017年佛山市HBsAg阳性产妇13 672例及其所分娩13 982例活产儿为研究对象，通过回顾性病历采集及前瞻性的随访追踪的方法，全面了解影响乙肝母婴阻断工作的主要因素。 结果2017年佛山市产妇HBsAg阳性率为10.14%，感染孕妇中HBeAg阳性率为24.13%，孕期HBV DNA检测率约5%，其中抗病毒治疗63例；新生儿乙肝免疫球蛋白接种率为99.84%；婴儿在出生后1年内完成乙肝疫苗三针接种的比率为81.71%，在完成三针乙肝疫苗接种的儿童中按照0-1-6程序接种的比率为62.65%；母婴阻断结果追踪率为40.16%，追踪儿童中母婴阻断失败34例，失败率为0.61%；产妇年龄低、HBeAg阳性、HepB未全程及规范接种是母婴阻断失败的危险因素(P<0.05)。儿童明确未检测的主要原因是拒绝检查、不知道要检查、提前检查和检测未提供结果，占99.07%。 结论加强信息沟通及健康教育，落实乙肝病毒感染产妇孕期DNA检测及抗病毒治疗，提高儿童乙肝疫苗的规范接种率，将暴露儿童的乙肝两对半检测纳入儿童保健管理工作，是实现全市乙肝母婴零传播的重要措施。     

基于指按法及针刺作用于手三里的痛温觉诱发电位探讨经络小纤维神经感传效应

目的观察比较指按法、针刺及痛温觉诱发电位(CHEPs)刺激器作用于正常人手三里产生的CHEPs,探析经络理论的小纤维神经感传方式。方法纳入16名健康成年志愿者,检测指按法、针刺、CHEPs刺激器作用于手三里产生的CHEPs,进行自身前后对照。结果3种刺激手段作用于受试者手三里均可记录到CHEPs,指按法诱发的N波潜伏期比CHEPs刺激器高120.69 ms(P<0.05),针刺诱发的N波潜伏期比CHEPs刺激器高183.69 ms(P<0.001)。指按法诱发的P波潜伏期比CHEPs刺激器高149.13 ms(P<0.05),针刺诱发的P波潜伏期比CHEPs刺激器高215.69ms(P<0.001),指按法和针刺N、P波潜伏期比较差异无统计学意义(P>0.05)。未见不同刺激手段对N、P波幅存在显著主效应(F=0.424,P=0.658;F=1.289,P=0.290)。结论指按法、针刺均可诱发由小纤维介导的N、P波,且通过与CHEPs刺激器诱发电位比较,指按法及针刺传导的小纤维速度更慢,为无髓鞘的C纤维;指按法、针刺诱发的N、P波波幅改变无明显差异。     

单侧液压脑损伤对大鼠双侧海马GFAP表达和CA1区突触传递的影响

目的研究单侧液压脑损伤(FPI)对大鼠双侧海马区胶质纤维酸性蛋白(GFAP)表达和CA1区突触传递的影响。方法建立大鼠单侧液压脑损伤模型,脑标本分为对照组(包括正常对照和假手术对照)、FPI损伤同侧组和FPI损伤对侧组。免疫组化法检测海马水平切片GFAP表达,对海马CA1区锥体神经元进行细胞内记录。结果FPI大鼠双侧海马齿状回门区和CA1区GFAP表达均比对照组明显增强。FPI损伤同侧组兴奋性输入-输出关系曲线的斜率比其他两组显著增大(P<0.05);FPI损伤同侧组和对侧组双脉冲易化(PPF)比值和抑制性突触后电位(IPSP)幅值均比对照组显著减小(P<0.05);FPI损伤同侧组和对侧组双脉冲抑制(PPD)比值均比对照组显著增大(P<0.05)。结论大鼠单侧液压脑损伤对双侧海马均可产生影响,导致双侧海马CA1区兴奋性突触传递增强,抑制性突触传递减弱。     

HBsAg母婴传播的研究

对HBsAg(+)母亲所生婴幼儿,连续两年的动态观察,发现这些婴幼儿的感染绝大多数皆在出生3个月后,其感染频率与母亲HBsAg的滴度成正相关,表明母婴传播阻断应以HBsAg(+)母亲所生之子女为重点对象。     

胃粘膜相关淋巴组织型淋巴瘤MAPK和Stat3磷酸化及cyclinD1蛋白表达的意义

目的:研究胃粘膜相关淋巴组织型(MALT)淋巴瘤MAPK和Stat3磷酸化与cyclinD1蛋白表达及其意义。方法:利用免疫组织化学方法检测了45例胃MALT淋巴瘤MAPK和Stat3磷酸化及cyclinD1蛋白的表达。结果:在胃MALT淋巴瘤中p-MAPK、p-Stat3及cyclinD1蛋白的阳性率分别为73.3%(33/45)、64.4%(29/45)和68.9%(31/45);低度恶性组p-MAPK和cyclinD1蛋白的阳性表达强度明显高于高度恶性组(P<0.01),而p-Stat3表达强度无明显差异(P>0.05);在低度和高度恶性胃MALT淋巴瘤中p-MAPK和cyclinD1蛋白的阳性信号强度均呈明显的正相关(r=0.6572和0.6823,P<0.01),而p-Stat3与cyclinD1蛋白表达未见明显相关性(r=0.1927,P>0.05)。结论:提示MAPK磷酸化在胃MALT淋巴瘤中发生及演进过程中起重要作用,但Stat3的磷酸化可能与该肿瘤的恶性演进关系不明显;在胃MALT淋巴瘤的发生与发展中,p-MAPK可诱导cyclinD1过度表达,从而促使该肿瘤细胞维持高增殖状态。     

新生儿出生信息样本分析

目的:了解和探讨新生儿出生信息的分布态势及规律。方法:对本院2006年1~6月间所有新生儿出生信息进行样本分析。结果:半年间分娩的新生儿共1075例,其中死亡19例,双胞胎15例,以1028例单胎活产新生儿的出生体重、胎龄及产妇年龄作为研究样本进行分析,统计数据与传统意义上的正常胎龄和新生儿体重基本相符,胎龄、体重均值均有所提高。结论:孕产妇的健康状况和新生儿的体质均有所改善,随胎龄的增加,新生儿出生体重亦随之增加,并且,目前新生儿的整体统计体重要大于现有的临床指标,因此,应对现有的临床指标进行适当调整,重新确定低出生体重儿和巨大儿的临床指标。     

Pharmacology of the internal anal sphincter and its relevance to faecal incontinence

1 The internal anal sphincter (IAS) has a spontaneous tone and is the main contributor to the maintenance of faecal continence. The spontaneous resting tone exhibited by the sphincter can be modified by neurotransmitters from the autonomic and enteric nervous systems. 2 In this review, the influence of the sympathetic and parasympathetic nervous systems on IAS tone are discussed and the putative roles of nitric oxide, carbon monoxide, vasoactive intestinal peptide and adenosine triphosphate in non‐adrenergic non‐cholinergic transmission are considered. 3 Faecal incontinence is a common condition that places a heavy financial burden on the health service and severely affects patients’ quality of life. Resting anal pressure is reduced in patients with faecal incontinence and agents that increase sphincter tone tend to relieve symptoms. The results of clinical studies of the use of phenylephrine to treat faecal incontinence are reviewed. 4 It is concluded that the IAS is a potential target for drug development for the treatment of faecal incontinence.
