疏血通对慢性阻塞性肺疾病合并肺动脉高压患者血清D-二聚体与呼吸功能的影响

【摘要】 目的 观察疏血通注射液对慢性阻塞性肺疾病（COPD）合并肺动脉高压患者血清D 二聚体（D D）的影响及呼吸功能改善作用。方法 将我院收治的80例COPD合并肺动脉高压患者随机分为观察组与对照组各40例，均给予吸氧、支气管舒张剂、糖皮质激素、抗生素、营养支持等常规治疗，观察组在此基础上给予疏血通注射液，两组均治疗21d。比较两组凝血功能，检测血气指标、肺动脉压、肺功能指标，评估呼吸系统评分，统计治疗过程中的不良反应。结果 观察组治疗21d后凝血酶原时间（PT）、活化部分凝血活酶时间（APTT）显著高于对照组（P＜005），纤维蛋白原（FIB）、D D显著低于对照组（P＜005）。观察组治疗21d后动脉血氧分压（Pa02）、用力呼气1s率（FEV1/FVC）分别为（7124±1284）mmHg、（5784±1043）%显著高于对照组的（6536±1177）mmHg、（5241±945）%（P＜005），动脉血二氧化碳分压（PaC02）、肺动脉收缩压分别为（4541±819）mmHg、（4016±720）mmHg显著低于对照组的（5002±901）mmHg、（4473±806）mmHg（P＜005）。结论 疏血通可以改善COPD合并肺动脉高压患者血液高凝状态，增加血氧含量，降低肺动脉高压，改善呼吸功能。     

血清窖蛋白-1在慢性阻塞性肺疾病相关肺动脉高压患者中的表达及意义

目的 研究血清窖蛋白-1 （Cav-1） 在慢性阻塞性肺疾病 （COPD） 相关肺动脉高压 （PAH） 患者中的表达及其意义。方法 选取稳定期COPD患者65例， 根据是否合并PAH分成COPD组 ［肺动脉收缩压 （PASP） ＜40 mmHg， 35例］ 及COPD-PAH组 （PASP ≥40 mmHg， 30例）。另选取在本院健康体检的志愿者30例作为对照组。对比各组基线资料、 动脉血气分析、 肺功能指标， 以及血清Cav-1、 白细胞介素 （IL） -6和肿瘤坏死因子-α （TNF-α） 的表达水平。绘制受试者工作特征 （ROC） 曲线， 评价Cav-1对COPD合并PAH的诊断价值。结果 COPD-PAH组与COPD组第一秒用力呼吸容积 （FEV1） /用力肺活量 （FVC）、 FEV1占预计值百分比 （FEV1%） 及氧分压 ［p （O2 ）］ 低于对照组， 而二氧化碳分压 ［p （CO2 ）］、 PASP均高于对照组 （P＜0.01）。COPD-PAH组p （O2 ） 低于COPD组， p （CO2 ）、 PASP均高于COPD 组 （P＜0.01）。对照组、 COPD组及COPD-PAH组Cav-1表达水平呈逐渐降低趋势， 而IL-6、 TNF-α表达水平呈逐渐升高趋势 （P＜0.01）。血清Cav-1诊断COPD合并PAH的ROC曲线下面积为0.902 （0.821～0.955）， 最佳截断值为 6.66 μg/L， 此时诊断敏感度为76.7%， 特异度为85.7%， 与多普勒超声诊断仪测量PASP结果比较一致性较好 （Kappa 值=0.627）。结论 血清Cav-1在COPD相关PAH患者表达明显下调， 可以作为预测COPD相关PAH的新型血清标志物。     

Utility of the 3‐Vessel and 3‐Vessel and Trachea Views in Prenatal Diagnosis of a Pulmonary Artery Sling

A pulmonary artery (PA) sling is a very rare congenital cardiovascular anomaly, and only a few studies have reported PA slings in fetuses. The relationship of the PA, aorta, ductus arteriosus, and trachea can be evaluated in the 3‐vessel and 3‐vessel and trachea views during fetal echocardiography. A PA sling can be detected by abnormal positioning of the left PA in relation to the trachea when sweeping from the 3‐vessel view cranially to the 3‐vessel and trachea view. Here we report 3 cases of fetal PA slings and their follow‐ups. Two cases were confirmed by postnatal echocardiography, and the other case was confirmed by a cardiovascular cast after pregnancy termination. We emphasize that the 3‐vessel and 3‐vessel and trachea views are of crucial importance in the prenatal diagnosis of a PA sling.     

Learning to live with a hand nerve disorder: A constructed grounded theory

Study DesignGrounded theory.IntroductionThe broader perspective of health offered by the World Health Organization's International Classification of Functioning, Disability and Health has had a significant bearing on how we view the measurement of health outcomes after surgical or therapy interventions for peripheral nerve disorders affecting the hand. The value of the patient's perspective is now recognized and outcomes which reflect this are being advocated in the clinical management and support of this population.Purpose of the StudyThis qualitative study sought to explore the lived experience of a hand nerve disorder and in particular the impact on body structure/function, activities, and participation.MethodsIn depth, one-to-one interviews with 14 people with a range of hand nerve disorders were conducted. Constructivist grounded theory methods were used to collect and analyze the data. Patients were also given the option of taking photographs to visually represent what it is like to live with a nerve disorder, to bring with them for discussion during the interview.ResultsThe impact of hand nerve disorders forms part of a wider narrative on adaptation. A process of “struggling” and then “overcoming” was experienced. This was followed by an interior aspect of adaptation described as “accepting.” This gave rise to participants “transforming,” being changed as a result of the journey that they had been on.ConclusionsThis study provides an explanatory theory on the adaptive process following a hand nerve disorder which may inform future patient-therapist interactions.     

Comparison of Peripheral Blast Clearance and Day 14 Bone Marrow Biopsy in Predicting Remission Status and Survival After 7+3 Induction in Acute Myeloid Leukemia

Introduction

Induction chemotherapy with cytarabine and an anthracycline (7+3) remains the standard of care for acute myeloid leukemia (AML).
