宫腔镜检查在诊断子宫内膜息肉中的价值分析

通过比较超声、宫腔镜检查与病理诊断子宫内膜息肉的结果,以及超声诊断结果阴性的病例中,宫腔镜与病理诊断的差异检出率,探讨宫腔镜检查对正确诊断子宫内膜息肉的重要性.回顾性收集连续在我院妇科行宫腔镜检查且证实子宫内膜息肉诊断的住院患者共730例.总结各病例超声诊断、宫腔镜检查及病理诊断的结果.统计分析显示,三者诊断子宫内膜息肉的检出率分别为82.7％、93.4％、90.8％.其中,由超声检查漏诊的子宫内膜息肉患者共126例,宫腔镜及病理检出率分别为96.8％、88.1％,且两者的阴性结果互不重叠,这种诊断差异在超声诊断结果示内膜增厚/内膜厚薄不均病例中尤为显著.因此,子宫内膜息肉的诊断方式中,宫腔镜诊断检出率最高,但仍有漏诊的病例由病理确诊,研究认为宫腔镜检查是确诊子宫内膜息肉的重要诊断方法.     

超声联合微泡剂介导的肿瘤靶向治疗研究进展

包被气体的微泡剂作为超声造影剂不仅显著提高了临床超声显像诊断能力,而且其作为一种新型药物载体的靶向治疗作用正逐步被揭示。携带基因或药物的超声微泡剂介导肿瘤靶向治疗已经成为超声研究领域中的研究热点。这种微泡剂在超声能量作用下因空化效应导致自身破裂并定向释放所携带的药物或者基因,使特定肿瘤组织或细胞部位浓度大大提高,从而起...     

Obstetric Ultrasound and the Technological Mediation of Morality: A Postphenomenological Analysis

This article analyzes the moral relevance of technological artifacts and its possible role in ethical theory, by taking the postphenomenological approach that has developed around the work of Don Ihde into the domain of ethics. By elaborating a postphenomenological analysis of the mediating role of ultrasound in moral decisions about abortion, the article argues that technologies embody morality and help to constitute moral subjectivity. This technological mediation of the moral subject is subsequently addressed in terms of Michel Foucault’s ethical position, in which ethics is about actively co-shaping one’s moral subjectivity. Integrating Foucauldian ethics and postphenomenology, the article argues that the technological mediation of moral subjectivity should be at the heart of an ethical approach that takes the moral dimensions of technology seriously.

纳米级超声造影剂的哲学思考

微创医学中的介入性超声

超声检查具有实时、动态、灵活、方便等优点,在临床上有重要作用。介入性超声是在超声显像的基础上,为进一步满足临床诊断和治疗的需要而发展起来的一门新技术,在微创医学体系中占有非常重要的地位,但只有与其它微创技术联合应用才更有活力和生机。     

平板运动试验结合颈动脉斑块检测诊断冠心病

探讨平板运动试验(TET)结合颈动脉斑块检测在诊断冠心病的临床意义。对166例疑诊冠心病患者进行冠状动脉造影(CAG),TET,颈动脉斑块检查,以CAG的诊断结果为金标准,分析TET,颈动脉斑块检查,TET结合颈动脉斑块检查诊断冠心病的敏感度、特异度。比较三者诊断冠心病的敏感度、特异度。三者敏感度分别为71.4%、64.3%、96.0%。特异度分别为65%、60.0%、82.4%。后者较前两者敏感度、特异度P<0.05。TET结合颈动脉斑块检查可显著提高冠心病的诊断率,不失为CAG前的筛选方法。

Atypical speech lateralization in adults with developmental coordination disorder demonstrated using functional transcranial Doppler ultrasound

Research using clinical populations to explore the relationship between hemispheric speech lateralization and handedness has focused on individuals with speech and language disorders, such as dyslexia or specific language impairment (SLI). Such work reveals atypical patterns of cerebral lateralization and handedness in these groups compared to controls. There are few studies that examine this relationship in people with motor coordination impairments but without speech or reading deficits, which is a surprising omission given the prevalence of theories suggesting a common neural network underlying both functions. We use an emerging imaging technique in cognitive neuroscience; functional transcranial Doppler (fTCD) ultrasound, to assess whether individuals with developmental coordination disorder (DCD) display reduced left‐hemisphere lateralization for speech production compared to control participants. Twelve adult control participants and 12 adults with DCD, but no other developmental/cognitive impairments, performed a word‐generation task whilst undergoing fTCD imaging to establish a hemispheric lateralization index for speech production. All participants also completed an electronic peg‐moving task to determine hand skill. As predicted, the DCD group showed a significantly reduced left lateralization pattern for the speech production task compared to controls. Performance on the motor skill task showed a clear preference for the dominant hand across both groups; however, the DCD group mean movement times were significantly higher for the non‐dominant hand. This is the first study of its kind to assess hand skill and speech lateralization in DCD. The results reveal a reduced leftwards asymmetry for speech and a slower motor performance. This fits alongside previous work showing atypical cerebral lateralization in DCD for other cognitive processes (e.g., executive function and short‐term memory) and thus speaks to debates on theories of the links between motor control and language production.     

超声引导下微创治疗子宫肌瘤

目前正式报道的超声引导下微创治疗子宫肌瘤的方法有两大类：（1）局部热消融治疗：在超声准确定位监视下或超声引导下将物理高温导入子宫肌瘤结节内,将肌瘤组织热凝固灭活,包括高强度聚焦超声、微波消融及射频消融。（2）在超声引导下向肌瘤内注入凝固剂或化疗药物灭活肌瘤组织。各种局部热消融治疗方法在消融范围内均可将肌瘤细胞有效灭活,疗效可靠,治疗后肌瘤可有效缩小、临床症状明显改善或消失,对正常生理功能影响很小或无明显影响。各种方法中,高强度聚焦超声无创伤,但治疗所需时间较长;微波或射频热效率高,治疗耗时短,但需肌瘤穿刺。肌瘤内注入凝固剂或药物操作方便,但由于药物弥散的因素适合3cm以下肌瘤的治疗。超声引导微创治疗子宫肌瘤创伤小、保留子宫,在有效使肌瘤缩小并控制临床症状的同时对患者的生理功能无影响或影响很小,并发症少,术后恢复快,有望成为治疗子宫肌瘤的主要方法之一。但治疗前应排除子宫恶性病变,并严格掌握适应证。
