目的探讨双侧慢性硬膜下血肿(bCSDH)单侧钻孔引流术后对侧血肿进展(CHP)的危险因素。方法回顾性研究2011年11月至2021年4月在首都医科大学附属北京天坛医院神经外科学中心接受单侧钻孔引流术的87例bCSDH患者的临床资料。术后3个月根据对侧血肿是否进展分为CHP组和无CHP组。对比分析两组患者临床资料的差异,对差异有统计学意义的变量采用多因素logistic回归方法分析影响CHP的相关危险因素。结果术后3个月,87例患者中16例发生CHP,发生率为18.4%,其中9例发生于术后1个月内,7例发生于术后1~2个月。5例患者经保守治疗血肿吸收,11例患者采用手术清除血肿。术后6个月内手术侧血肿复发2例,均为无CHP患者。与71例无CHP组患者对比,16例CHP组患者拔管前对侧血肿的最大厚度明显增大(P<0.001),对侧血肿位于曲侧(P=0.018)、血肿范围为广泛型(P=0.001)、CT密度为混杂型(P=0.034)患者的占比高。仅对术前的相关因素进行多因素logistic回归分析显示,对侧广泛型血肿(OR=5.34,95%CI:1.29~22.06,P=0.021)是CHP的危险因素;纳入术后变量进行分析后,对侧广泛型血肿(OR=4.60,95%CI:1.02~20.72,P=0.047)、拔管前对侧血肿最大厚度增大(OR=21.99,95%CI:1.85~260.81,P=0.014)是CHP的危险因素。结论bCSDH患者行单侧颅骨钻孔引流术后2个月内是CHP的高发期。对侧广泛型血肿、拔管前对侧血肿最大厚度增大是术后CHP的独立危险因素。

目的采用倾向性评分匹配(PSM)分析血管性血友病因子(vWF)对重症监护病房(ICU)患者发生静脉血栓栓塞症(VTE)的预测价值。方法纳入2020年12月至2022年6月昆明医科大学第二附属医院ICU收治的ICU住院时间≥72 h且每日行床旁血管超声筛查的患者。收集患者年龄、性别、原发病、慢性合并症等基线资料,以及入ICU前和入ICU 24 h、48 h的凝血指标,包括凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)、国际标准化比值(INR)、纤维蛋白原(Fib)、纤维蛋白单体(FM)、vWF、D-二聚体、抗凝血酶Ⅲ(ATⅢ)等。根据是否发生VTE〔VTE诊断:患者每日行床旁血管(双上下肢、内脏静脉)超声筛查,怀疑有血栓者由超声科医生复查确诊或肺动脉造影确诊〕将患者分为VTE组和非VTE组。采用PSM分析方法,以VTE组为基准,对年龄、是否有恶性肿瘤、是否有感染、是否合并糖尿病及入ICU前凝血指标进行1∶1匹配,得到组间协变量均衡的样本。采用多因素Logistic回归分析筛选VTE发生的危险因素;绘制受试者工作特征曲线(ROC曲线),评价vWF对重症患者发生VTE的预测价值。结果共纳入120例患者,其中18例(15.0%)入ICU后72 h内确诊发生VTE,102例(85.0%)在ICU内未发现血栓。PSM前,VTE组与非VTE组患者年龄、性别、合并恶性肿瘤和感染比例及凝血指标差异均有统计学意义。PSM后,成功匹配14对,两组间不平衡的协变量均达到均衡。多因素Logistic回归分析显示,入ICU 48 h vWF是重症患者发生VTE的独立危险因素〔优势比(OR)=1.165,95%可信区间(95%CI)为1.000~1.025,P=0.004〕。ROC曲线分析显示,入ICU 48 h vWF预测重症患者发生VTE的ROC曲线下面积(AUC)为0.782,95%CI为0.618~0.945,P=0.007;当最佳截断值为312.12%时,敏感度为67.7%,特异度为93.0%。结论动态监测vWF有助于判断ICU患者发生VTE,入ICU 48 h vWF对VTE发生有一定预测价值。

目的对比管道镜与常规法在消化内镜管腔清洗效果评价中的应用,探讨管道镜在消化内镜日常清洗质量监测中应用的可行性。方法选择2023年7—9月河南省人民消化内镜中心100条使用后的胃镜,使用随机数字表法分为管道镜组和常规组,每组50条,两组内镜外表面清洗质量均采用目测法检查,两组内镜管腔清洗质量检查分别采用管道镜和常规气枪吹气法检查。结果管道镜组检测出内镜清洗不合格数量(16条)高于常规组(3条),差异有统计学意义(P<0.05)。常规组3条清洗不合格内镜的原因均为残留污物,管道镜组内镜清洗不合格的原因中9条(56.25%)为吸引管道中残留白色微小颗粒污染物,4条(25.00%)为残留污物,3条(18.75%)为注气/注水活塞口底部边缘存在锈迹。结论管道镜相比常规检查法,内镜护士可以对管腔进行直视观察,准确判断内镜管腔内部的清洗质量,弥补常规检查法的不足,提高了内镜清洗不合格检出率,可以作为消化内镜日常清洗质量效果监测的方法。

Background Moyamoya disease (MMD) is a rare and complex cerebrovascular disorder characterized by the progressive narrowing of the internal carotid arteries and the formation of compensatory collateral vessels. The etiology of MMD remains enigmatic, making diagnosis and management challenging. The MOYAOMICS project was initiated to investigate the molecular underpinnings of MMD and explore potential diagnostic and therapeutic *** The MOYAOMICS project employs a multidisciplinary approach, integrating various omics technologies, including genomics, transcriptomics, proteomics, and metabolomics, to comprehensively examine the molecular signatures associated with MMD pathogenesis. Additionally, we will investigate the potential influence of gut microbiota and brain-gut peptides on MMD development, assessing their suitability as targets for therapeutic strategies and dietary interventions. Radiomics, a specialized field in medical imaging, is utilized to analyze neuroimaging data for early detection and characterization of MMD-related brain changes. Deep learning algorithms are employed to differentiate MMD from other conditions, automating the diagnostic process. We also employ single-cellomics and mass cytometry to precisely study cellular heterogeneity in peripheral blood samples from MMD *** The MOYAOMICS project represents a significant step toward comprehending MMD’s molecular underpinnings. This multidisciplinary approach has the potential to revolutionize early diagnosis, patient stratification, and the development of targeted therapies for MMD. The identification of blood-based biomarkers and the integration of multiple omics data are critical for improving the clinical management of MMD and enhancing patient outcomes for this complex disease.
