EVALUATION OF BIOFEEDBACK IN THE TREATMENT OF BORDERLINE ESSENTIAL HYPERTENSION1

Direct biofeedback of blood pressure was compared with frontal EMG biofeedback and with self-instructed relaxation for the treatment of essential hypertension in a controlled group outcome study. Patients were followed up for four months after the end of treatment. Generalization of treatment effects was assessed through pre- and posttreatment measurements of blood pressure under clinical conditions in a physician's office. There were no significant reductions in diastolic blood pressure. The systolic blood pressure (SBP) of the patients receiving blood pressure biofeedback decreased 8.1 mm mercury (p = 0.07) and the SBP of the patients in the relaxation condition decreased 9.5 mm mercury (p = 0.05). In the generalization measures, there were significant reductions in SBP for the relaxation group. The results are discussed in terms of the general lack of replicability within the area of biofeedback treatment of hypertension.     

腔内泌尿外科技术应用中的若干思考

近年来腔内泌尿外科迅速发展,在泌尿外科领域广泛应用.回顾历史,腔内泌尿外科器械是在与多种学科相互交叉和渗透的过程中发展的,学科交叉促进了腔内泌尿外科器械的发展和应用;腔内泌尿外科技术是医学人文关怀的体现,符合现代医学模式的要求.我们应加强医学与其它学科的交叉,促进腔内泌尿外科的发展,使疾病诊治更具人文精神.     

呼吸危重症临床决策中的若干问题

在临床实践中,呼吸危重症的诊断和治疗存在着一些不同的观点。就其中某些热点问题,如慢性阻塞性肺疾病合并哮喘的诊断和机械通气的指征、肺栓塞的诊断、急性呼吸窘迫综合征的治疗、呼吸重症监护病房的建设和呼吸危重症的伦理学问题进行阐述,以期提高对呼吸危重症的认识。     

高血压脑出血急诊救治现状与进展

高血压脑出血是指在高血压的情况下发生的脑实质内出血。目前急诊综合救治中内科药物和外科手术治疗为主要的两种方法。内科治疗只适用于轻度脑出血和有手术禁忌证及配合急诊外科手术的综合救治,外科手术多用在中、重度脑出血病人治疗中。近年来开展的一种在CT下三维定位脑内血肿清除术,以其定位准确,脑损伤小,在急诊救治方面取得了一定效果,有待于进一步发展。     

Daily stress and anxiety and their relation to daily fluctuations of symptoms in asthma and chronic obstructive pulmonary disease (COPD) patients

Although stress and anxiety have long been assumed to play an exacerbatory role in asthma, no study has systematically documented that daily exacerbations of asthma symptoms are related to stress and/or anxiety. In this study, 24 airways obstruction patients (12 asthmatics and 12 chronic obstructive pulmonary disease patients) were instructed to monitor the severity of daily respiratory symptoms. In addition, subjects recorded their daily anxiety level and the number and perceived impact of daily stressors. The results showed that although there were differences between high- and low-stress days for both groups, there were no differences between groups on symptom severity or between high- and low-anxiety days, as measured by the State-Trait Anxiety Inventory (STAI). Thus, although the number and impact of daily stressors were found to be directly associated with the severity of asthma symptoms, anxiety does not appear to have a direct role in the exacerbation of asthma. The findings failed to support the anxiety theory of asthma but provided an explanation for the poor results obtained in previous treatment studies which employed anxiety management with asthmatics.     

动脉功能评价与降压质量

高血压的治疗中降压是最重要的原则,降压达标可以带来心血管事件的下降已是不争的事实。流行病学调查证实动脉功能是心血管事件的独立预测因子。动脉功能的评价不仅可以筛查高危人群,还可作为降压质量评价的指标,临床研究已证实其意义。未来的高血压治疗领域,除监测血压外,可能需要监测和评估动脉功能。     

关注降压药物的选择，促使更有效的降压达标

我国成人高血压患病率高达18.8%,全国有高血压患者约1.6亿。合理的药物治疗是降压达标的主要措施,如何进行正确选择成为摆在我们面前的难题。目前,降压药物主要包括利尿剂、β受体阻断剂、血管紧张素转换酶抑制剂、血管紧张素Ⅱ受体拮抗剂、钙拮抗剂和α受体阻断剂6类。因降压治疗的收益主要来自于降压本身,为了提高降压达标率及高血压患者的用药依从性,目前多主张低剂量联合治疗。     

17α-羟化酶缺陷症2例报告及文献总结

17α-羟化酶缺陷症（17α-OHD）是先天性肾上腺皮质增生症（CAH）的一种罕见类型,很容易漏诊和误诊。17α-OHD是一种常染色体隐性遗传性疾病,可导致糖皮质激素合成减少,促肾上腺皮质激素增多;性腺激素合成减少,而促性腺激素反馈性增高,同时可伴有盐皮质激素水平的升高。对该疾病的早期诊断非常重要,早期诊断并予以激素替代治疗对提高患者生活质量有很大帮助。现报道2例我科17α-OHD的诊治经过,以提高对本病的认识。     

高龄老年高血压患者的降压治疗策略

80岁以上高龄老年高血压患者的降压治疗随着人口老龄化而越来越受关注。评估高龄高血压患者降压治疗的获益与风险,在循证医学基础上进行个体化治疗,依据全身情况和耐受程度调整血压控制水平,慎重选择药物,平稳缓慢降压,将使高龄高血压患者最大程度受益。
