CA153联合CA199对良恶性腹腔积液的鉴别诊断价值

目的探讨腹腔积液中CA153联合CA199对良恶性腹腔积液的鉴别诊断价值。方法选择98例腹腔积液患者,经手术病理诊断为恶性腹腔积液者为观察组(48例),良性腹腔积液者为对照组(50例)。检测并比较2组患者腹腔积液中的CA153、CA199水平及CA153、CA199的阳性结果,分析CA153及CA155单用及联合应用对恶性腹腔积液的诊断效能。结果观察组腹腔积液中的CA153及CA199水平均明显高于对照组,P <0. 05。观察组CA153及CA199阳性率明显高于对照组,P <0. 05。CA153、CA199对恶性腹腔积液诊断的敏感性、特异性及准确性对比,差异无统计学意义(P> 0. 05);CA153+CA199的敏感性、特异性及准确性明显高于单项CA153及CA199(P <0. 05)。结论 CA153与CA199单项检测对恶性腹腔积液的诊断价值有限,CA153+CA199对恶性腹腔积液的诊断价值较高,值得临床推广应用。     

进展型脑梗死患者miRNA的表达水平及临床意义

目的探讨进展型脑梗死患者微小RNA(miRNA)的表达水平及临床意义。方法回顾性分析2016年7月至2018年7月期间我院收治的138例脑梗死患者病例资料。根据斯堪的那维亚卒中量表(SSS)将其分为对照组(稳定型脑梗死,82例)和观察组(进展型脑梗死,56例)。观察组患者按照高级中枢损伤严重程度评定标准(MESSS)评分为轻度进展(30例)、中度进展(17例)、重度进展(9例)三个亚组。对观察组出院两个月后进行预后随访,并将其分为预后不良组及预后良好组。分析进展型脑梗死患者miRNA的表达水平及临床意义。结果进展型脑梗死患者的miRNA-21、miRNA-223水平均显著高于稳定型脑梗死患者(P 0. 05); miRNA-21、miRNA-223的高表达均是进展型脑梗死的危险因素(P 0. 05),且进展型脑梗死的严重程度与血清miRNA-21、miRNA-223的表达水平均呈正相关(r=0. 834,P=0. 008;r=0. 896,P=0. 001)。预后不良组患者血清miRNA-21、miRNA-223表达水平显著高于预后良好组(P 0. 05);血清miRNA-21、miRNA-223表达水平预测进展型脑梗死预后的AUC面积分别为0. 805、0. 834,并分别得出截断值4. 45 (敏感度77. 14%,特异性82. 28%)、7. 06(敏感度82. 86%,特异性73. 42%)。结论进展型脑梗死患者miRNA-21、miRNA-223呈高表达,且其表达水平与脑梗死严重程度呈正相关,同时对预测进展型脑梗死预后均具有较高的敏感度和特异度,有可能成为一种早期诊断和预测进展型脑梗死生物标志物。     

Hacia el buen gobierno por la salud: incorporación de la diversidad de percepciones en salud urbana

ObjectiveTo analyse the similarities and differences in the discourse surrounding the conceptualisation of health and the perceived health assets and needs in the neighborhoods and city of Bilbao in a participatory process.MethodParticipatory workshops were held with professionals, neighbors and associated citizens. The differences in perceptions of the three content blocks were analysed on the basis of the health model referred, as well as the typologies —of a more individual or structural nature— of identified health needs and assets.ResultsThe conceptualisation of health from a biopsychosocial perspective was clearer among professionals, although both profiles pointed to the importance of its social determinants. The formulation of needs and assets in health by the neighbors was made from the impact on their daily life and from a position of users with respect to a service provider administration. Among the associated citizens and professionals, intermediate and structural determinants were more frequently mentioned, as well as issues related to the administration's scope of action.ConclusionsThe inclusion of the multiplicity and diversity of perceptions in planning is key to good local government for health. To address their contradictions, a commitment by governments to effectively incorporate citizen participation is needed.     

Molecular study of hypersensitivity to spores in adults and children from Castile & Leon

Introduction and objectivesBiological aerosols play a vital role in the interactions between the atmosphere, biosphere, climate and public health and fungal spores are a component with allergic importance.We constructed a database in Castile & Leon (Spain) and carry out molecular-level component-resolved diagnosis to complete the air quality study carried out since 2006 by our aerobiological network (RACYL) to aid clinical diagnosis and treatment.MethodsWe reviewed a database of 19,774 patients (adults and children) with allergic respiratory disease treated in our unit during the last 12 years. We also made a component-resolved diagnosis of the molecules involved in the pathology in a randomly selected population of 150 patients.ResultsThe dimeric glycoprotein Alt a1 from Alternaria is the most prevalent and most useful allergen in the diagnosis of patients with allergy to fungi in our area (94.4%), followed by enolase Alt a 6 (Alternaria), ribonuclease Asp f 1 of Aspergillus and mannitol dehydrogenase from Cla h 8 (Cladosporium).ConclusionsOur results have helped determine which spore molecules are most-closely associated with allergies. Molecular analysis will be useful to determine more accurate and useful immunotherapy in these patients.     

早期胃癌内镜治疗后追加外科手术病例特点、适应证和术式选择

内镜治疗技术的发展进一步推动了早期胃癌的微创治疗。然而，随之而来的问题是，部分接受内镜治疗的病人会出现非治愈性切除。早期胃癌内镜治疗后非治愈性病人的后续处理原则值得进一步关注。结合欧洲肿瘤内科学会（ESMO）、美国国家综合癌症网络（NCCN）及日本胃癌学会等国际指南及相关临床研究并回顾分析单中心数据后可得出结论，eCura-C的病人具有相对较高的癌残留风险，在与病人充分沟通后可考虑追加手术，但仍有较高的术后病理学无癌残留的风险。术式选择和切除范围可参考早期胃癌相关规定。如何准确预测非治愈性病人的淋巴结转移仍是未来的重点。前哨淋巴结活检及腹腔镜内镜联合手术是未来的发展方向。     

Congenital high airway obstruction syndrome (CHAOS): Natural history,prenatal management strategies,and outcomes at a single comprehensive fetal center

PurposeCongenital high airway obstruction syndrome (CHAOS) is a devastating fetal condition of complete airway discontinuity resulting in significant hydrops and extreme lung hyperplasia. It is universally fatal with survival reported only in the rare spontaneous fistulization or EXIT intervention (Ex Utero Intrapartum Treatment). Even in these cases, mortality remains high, and current investigations are targeting prenatal interventions. This report describes our experience with management and fetal interventions for CHAOS, including laser laryngotomy.MethodsWe retrospectively reviewed all patients diagnosed with CHAOS at a single academic institution between 2006 and 2017.ResultsFifteen patients were identified. Eight had obstruction at the trachea and seven at the larynx. In the laryngeal obstructions, three expired shortly after birth, and one survived after spontaneous fistulization and subsequent EXIT to tracheostomy. The remaining three underwent in-utero treatment with laser laryngotomy. One had preterm premature rupture of membranes (PPROM), delivered 3 days post-operatively, and died. Two underwent EXIT to tracheostomy with one surviving to discharge and is currently 2 years old.ConclusionOur study demonstrates the outcomes of a large series of patients diagnosed with CHAOS. While mortality remains high, options for fetal intervention are being explored to allow alterations in the prenatal natural history and improve postnatal outcomes.Type of StudyRetrospective Treatment Study.Level of EvidenceLevel IV.     

Dermoscopic features of hidroacanthoma simplex: Usefulness in distinguishing it from Bowen's disease and seborrheic keratosis

Hidroacanthoma simplex (HAS) is a rare benign eccrine adnexal tumor. HAS is sometimes clinically or pathologically misdiagnosed as squamous cell carcinoma in situ (Bowen's disease; BD), seborrheic keratosis (SK) or other adnexal tumor. To date, there has never been a report focusing on dermoscopic features to distinguish HAS from BD and SK. We found the following dermoscopic findings to be characteristic of HAS: fine black dots/globules (75% of cases) and fine scales arranged annularly (100% of cases). In contrast, glomerular vessels, which are typically observed in BD, were not seen in any of the four cases. Cerebriform appearance and milia‐like cysts, which are typically observed in SK, were also not seen in any of the four cases. The existence of “scattered fine black dots/globules” and “fine scales arranged annularly”, and the absence of the glomerular vessels, may contribute to precise diagnosis of HAS. Even though HAS resembles BD or SK clinically, it can be distinguished from these by the characteristic dermoscopic features.     

胃肠道间质瘤诊断方法的研究进展

胃肠道间质瘤（gastrointestinal stromal tumor，GIST）是起源于胃肠道间叶组织的肿瘤，由于GIST存在恶性潜能，且多数GIST患者无明显临床症状，所以GIST的早期发现、诊断和治疗显得尤为重要。GIST通常在内窥镜、超声内镜（endoscopic ultrasound，EUS）检查中发现。GIST的诊断取决于形态学和免疫组织化学染色，因此组织样本的充足性是其关键。近年来，新的成像技术的应用和分子生物学的发展提高了GIST的诊断准确率，并为GIST的预后及辅助治疗提供了依据。     

乳腺癌21基因检测的研究进展

乳腺癌是一类具有异质性的肿瘤，不同患者的治疗方法和疗效都不相同。尽管目前仍在努力为激素受体（hormone receptor，HR）阳性（+）、人表皮生长因子受体2（human epidermal growth factor receptor 2,HER-2）阴性（-）、淋巴结（axillary lymph node，ALN）阴性（-）的早期乳腺癌患者寻找合适的治疗方法，但其术后是否需要化疗仍然是肿瘤科医生面临的一个难题。以往治疗主要依赖于经典的组织病理学和免疫组织化学技术，随着精准医疗时代的到来，我们需要更定量的诊断方法和合理的个体化治疗。虽然化疗可降低疾病复发风险并提高生存率，但它带来的不良反应事件会降低患者的生活质量，尤其低复发风险（recurrence risk,RS)有可能超过化疗益处。21基因检测不仅可以预测这类早期乳腺癌化疗疗效及评估预后，还可提供精准的个体化治疗方案指导用药，为患者增添信心。本文就乳腺癌21基因检测的研究进展进行综述。
