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.     

血清血管紧张素转换酶的水平在阻塞性睡眠呼吸暂停低通气综合征患者中的变化研究

目的检测阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者中血清血管紧张素转换酶(ACE)水平的变化及其临床意义。方法设置OSAHS组(n=40)和健康对照组(n=40),测定并比较患者的血压、血脂和血清ACE水平在两组间的差异;分析ACE水平与患者病情变化、血压、血脂的相关性。结果 OSAHS患者在体重、BMI指数、颈围、腰围、AHI、收缩压、舒张压、TC、LDL-C和血清ACE方面高于健康人(P体重=0.002,P颈围=0.024,P腰围=0.038,PBMI=0.019,PAHI=0.001,P收缩压=0.001,P舒张压=0.001,PTC=0.017,PLDL-C=0.010,PACE=0.039),在LSa O2上低于健康人(PLSa O2=0.001)。OSAHS患者的收缩压、TC、ACE在轻中度和中重度之间均存在统计学差异(P收缩压=0.018、0.043,PTC=0.045、0.034,PACE=0.030、0.001),相关性分析显示,OSAHS患者中血清ACE与收缩压和TC均呈正相关(r=0.35,P=0.017;r=0.28,P=0.044)。结论 OSAHS患者血清ACE能反映患者病情的变化,并与血压和血脂具有一定相关性。     

8周基础军训对入伍新兵红细胞及其相关指标的影响

目的探讨8周基础军训(basic military training,BMT)对入伍新兵血像中红细胞及其相关指标的影响,为指导科学的军事训练提供参考。方法数据来自新疆边防部队2015年度入伍的50名男性新兵,分别在BMT前后测定并记录受试新兵的红细胞计数、血红蛋白浓度及血清铁蛋白等。结果经过8周的BMT,新兵血液中血红蛋白浓度、红细胞计数及血清铁蛋白均显著下降(P0.05,P0.01)。结论 8周BMT可能导致入伍新兵发生运动性贫血,铁缺乏可能是其主要原因。     

Advance in Functional Restoration of Injured Nerve with Low Level Laser and its Utilization in the Dental and Maxillofacial Region

The inferior alveolar nerve and facial nerve are the two most important nerves in the dental and maxillofacial region. The injury to them is one of the major postoperative complications after alveolar surgery and orthognathic surgery. However, recovering the nerve function after injury takes a long time and the recovery effect tends to be unsatisfactory. In recent years, an intensively investigated technique, low level laser which has been applying in assisting the recovery of nerve function, has been gradually proved to be effective in clinically treating postoperative nerve injury. In this article we review in terms of the mechanisms involved in low level laser-assisted functional restoration of nerve injury and its clinical application in the recovery of nerve function in the dental and maxillofacial area as well.     

抗PD-(L)1、抗CTLA-4免疫治疗标志物研究进展

免疫检查点抑制剂已经改变了包括肺癌、黑色素瘤等许多肿瘤的治疗情况，并且在一些难治性肿瘤中表现出持久的应答率，然而在部分接受治疗的患者中表现出无反应及严重免疫相关副作用。为了优化免疫疗法的使用，可能需要多种临床应答的预测性标志物。本研究回顾了几种潜在有效生物标志物的可用数据，通过免疫组化检测肿瘤细胞和免疫细胞中PD-L1的表达，提示其是一种临床疗效的良好预测标志物;且PD-L1表达阴性者经免疫治疗后仍可获益。PD-L1表达在肿瘤内是动态和异质性的:在原发性灶和转移灶之间或在穿刺标本和大体标本之间表达不一致。肿瘤突变负荷与新抗原的高比率可获得持久获益。外周血标志物也可作为潜在标志物，增加的绝对淋巴细胞计数（ALC）与疾病控制和生存显著相关。在这篇综述中，我们旨在讨论抗PD-（L）1与抗CTLA-4 免疫治疗相关标志物研究现状，为临床运用提供指导，以便能够准确筛选出从这些治疗中获益更多的患者。     

活血利水法在骨伤科疾病中的应用
