Atypical Abnormal Pulmonary Vein Drainage with Atrial Septal Defect: Surgical Treatment

Sinus venosus atrial septal defect (SV‐ASD) usually coexists with partial anomalous pulmonary vein connection (PAPVC). It is a difficult diagnosis in transthoracic echocardiography (TTE) due to eccentric position of defects. We present a rare case of atypical anatomical variation in PAPVC, which was never described before. Two right pulmonary veins drained into superior vena cava, which overrode SV‐ASD and interatrial septum, a third pulmonary vein into the right atrium. Complete diagnosis could not be set after TTE, nor transesophageal echocardiography, whereas angio‐CT was finally conclusive. This diagnostic approach allowed the surgical planning.     

半夏白术天麻汤治疗眩晕高血压病举隅

高血压病是我国发病率较高的疾病之一,西医治疗以长期服用降压药物为主要治疗方式,但常因依从性差的原因导致血压控制不佳,而用中医辨证治疗对于首次发现高血压的患者,可明显有效地降低高血压的发病率。高血压病在中医学中属"眩晕",在临床中常常会用半夏白术天麻汤来治疗眩晕,本文通过跟师医案及临床收集介绍半夏白术天麻汤治疗高血压眩晕临证方药的运用。     

高渗盐水和甘露醇在动脉瘤性蛛网膜下腔出血患者降低颅内压中的应用

目的比较3%高渗盐水和20%甘露醇治疗重症动脉瘤性蛛网膜下腔出血所致颅内压增高的疗效.方法25例动脉瘤性蛛网膜下腔出血患者出现颅内压增高事件时, 随机交替接受等渗透剂量的160 mL 3%高渗盐水与150 mL 20%甘露醇进行降低颅内压治疗, 连续监测患者颅内压、平均动脉压、脑灌注压及中心静脉压.记录有效降低颅内压持续时间、颅内压最大降幅及其时间, 用药前及用药后1 h、3 h血钠水平及血浆渗透压.结果3%高渗盐水和20%甘露醇均可降低颅内压(均 P < 0.01), 两者的降低颅内压作用持续时间及颅内压降幅差异均无统计学意义(均 P >0.05).患者脑灌注压较用药前均上升(均 P < 0.01), 平均动脉压先上升后下降, 但差异无统计学意义( P >0.05).患者中心静脉压稍有波动, 但差异均无统计学意义(均 P >0.05).20%甘露醇治疗后患者血钠下降, 3%高渗盐水治疗后患者血钠值上升, 变化均有统计学意义(均 P < 0.05).20%甘露醇及3%高渗盐水治疗后患者血浆渗透压均先上升后下降, 变化均有统计学意义(均 P < 0.01). 结论3%高渗盐水可作为治疗动脉瘤性蛛网膜下腔出血所致颅内压增高患者的一线治疗药物.     

Treatment strategies for hypertension in patients with type 1 diabetes

ABSTRACT

Introduction

Type 1 diabetes mellitus (T1DM) is a chronic, autoimmune disease that is characterized by total absence of insulin production. Hypertension is a common comorbidity in T1DM with complex pathophysiology, while it is also a well-recognized risk factor for the development of cardiovascular disease (CVD), as well as other microvascular diabetic complications.     

Mimengosides J and K: two new neuroprotective triterpenoids from the fruits of Buddleja lindleyana

Two new 11-methoxyl substituted triterpenoids, named as mimengosides J (1) and K (2), along with seven known compounds, were isolated from the fruits of Buddleja lindleyana. Their structures were elucidated on the basis of spectroscopic analysis. In addition, the new ones were evaluated for protective effects against damage of SH-SY5Y cells induced by 1-methyl-4-phenylpyridinium ion (MPP⁺) and the results indicated that those may be one of the candidate compositions of Buddleja lindleyana for the treatment of neurodegenerative disease.

     

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。     

Analysis of arterial hypertension pharmacotherapy in patients with obstructive sleep apnea syndrome

IntroductionObstructive sleep apnea (OSA) is often connected with arterial hypertension and it could also be a cause of secondary hypertension. Treatment of arterial hypertension and optimal blood pressure level are important for prevention of cardiovascular complications. It is not well known how to treat patients with OSA and arterial hypertension. Also many patients with OSA suffer from metabolic syndrome which worsen their prognosis.AimThe aim of our study was to assess arterial hypertension compensation in patients with metabolic syndrome and moderate to severe OSA and to analyze used pharmacotherapy.Materials and methods85 hypertensive patients (75 men) with metabolic syndrome, average age 53.6 ± 9.3 years, were evaluated using overnight sleep study with diagnosis of OSA, average apnea–hypopnea index (AHI) 56.3 ± 23. Patients underwent 24 h ambulatory blood pressure monitoring (ABPM) and their current pharmacotherapy data were obtained. Appropriate combinations of antihypertensive drugs (patients with metabolic syndrome) were derived from ESH/ESC 2013 guidelines.ResultsArterial hypertension was well compensated in only 11.8% of the patients. 24.7% patients were treated according to current guidelines. Fisher's exact test with analysis of adjusted residues has found higher rate of blood pressure subcompensation in patients treated with triple+ combination of drugs (p = 0.035, 51.4% vs 10%).ConclusionOnly a small number of patients had optimal blood pressure level and were treated according to current ESH/ESC guidelines. We have to constantly appeal to all physicians to perform ABPM in patients with OSA.
