超高压电缆线路局部放电重症监测系统实际应用

在电缆线路的带电局放检测中发现一个较为明显的疑似局放信号时,最需要解决的是如何在较短的时间内定性定量地判别和确认疑似局放的性质包括对疑似信号源的定位。为此,作者团队研发制造出一种适用于超高压电缆线路的局部放电重症监测系统装置,能够三四个测试通道使用同种类型或不同种类型传感器进行同时同步测试;能够同时提供局放信号的原波形（示波器功能）和频率分布（频谱仪功能）;能够对局放源进行定位;能够提供各种三维二维图谱;能够基于多重逻辑门程序和神经网络以及波形相关系数等多种自动局放识别程序进行自动甄别;能够通过网络通信实施多点异地的专家后台会诊。本论文通过实际应用案例,展示和说明了局放重症监测系统装置在实际的电缆线路局放测试中所起到的作用和有效性。

剖宫产术后留置导尿管放尿方法的改进

目的探讨对剖宫产术后患者采用早期定期开放尿管、缩短留置尿管时间,以及膀胱充盈时放尿方法的预后情况。方法选择239例剖宫产术后留置尿管患者随机分成两组：实验组采用新的放尿方法,共120例;对照组采用传统放尿方法,共119例,分别观察拔除尿管后第1次排尿的时间、排尿量、拔除导尿管后尿液化验结果。结果采用新的放尿方法的实验组,其第1次排尿量、自行排尿顺利率及拔除尿管时间均优于对照组,差异有显者性（P〈0.05）;实验组尿路感染发生率明显低于对照组,差异有显著性（P〈0.05）。结论剖宫产术后采用早期定期开放,缩短留置尿管时间,以及膀胱充盈时放尿的方法,对于产妇预后的影响较大,采用新的放尿方法简便有效,患者易于接受,切实可行。     

电力电缆线路局放测试及定位操练模型的研制(1)

电力电缆线路的带电局放检测已成为一种预防发生突发性故障和保供电的有效手段。由于运行线路上局放的存在和发生机率低,使得现场测试人员很难积累如何识别局放和定位局放的有效经验,局放检测技术始终难以掌握和普及。电力电缆线路局放测试及定位操练模型的研制目的就是要提供一个安全可靠,可触可视和可以根据需要而任意改形的微缩操练平台。作者认为,通过对在模型上的人工模拟局放的检测操练并结合局放自动检测定位程序帮助,可以促使测试人员深刻和准确地掌握有关电缆局放信号的行波特性,传感原理和检测识别方法;对电缆中间接头和电缆终端的局放测试方法、直接注入校正法与间接注入校正法比较、根据反射波时间和对向波时间差的定位原理均可进行模拟试验及验证,为电缆线路现场局放实测打好基础。     

腹腔大量放液对腹水患者机体状态影响的临床研究

目的：探讨腹水大量放液对血氨、离子浓度、腹水平均增长速率的影响。方法：对32例患者采取常规腹腔穿刺放液术,其腹水放液量均超过3000mL。在腹腔穿刺放液术前后,应用谷氨酸脱氢酶法测血氨的浓度,生化分析仪测定血清及腹水中离子的浓度,美蓝吸光度法测量腹水增长速率的变化。结果：（1）同一患者腹腔穿刺大量放液前后血清、腹水离子及血氨不存在明显差异（P〉0.05）;（2）非门脉高压性腹水的平均增长速率在腹腔穿刺放液前后比较,无统计学意义（P〉0.05）;而门脉高压性腹水组的在腹腔穿刺放液术后平均增长速率低于术前（P〈0.05）。结论：患者在未发生严重并发症,且静脉补充白蛋白的情况下：（1）腹腔穿刺大量放液未导致血氨的变化,未导致离子紊乱;（2）门脉高压性腹水有逐渐重吸收的趋势;非门脉高压性腹水患者腹腔穿刺大量放液可能与腹水平均增长速率的变化无关。

Survey and practice of reporting quality of randomized controlled clinical trials on traditional Chinese medicine

Evidence obtained from randomized controlled trials （RCTs） has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine （TCM） and results have shown that there is an urgent need for higher quality RCTs on TCM.     

TCM Treatment of Ankylosing Spondylitis by Tonifying the Kidney and Strengthening the Governor Vessel

Ankylosing spondylitis is a chronic and progressive disorder with inflammation mainly involving the central axis joints. It mainly affects the cervical spine and the lumbosacral area, with the pathogenesis closely related to the kidney and the Governor Vessel (GV). TCM holds that the syndrome is deficiency in origin and excess in superficiality, which is due to insufficiency of the kidney, deficiency of GV, and blocking of the channels with the invasion of exogenous evil, leading to poor circulation of qi and blood and malnutrition of the bones, muscles and joints. The TCM method of tonifying the kidney and strengthening GV to regulate circulation of qi and blood and check the arthralgia pain should be adopted, with the Kidney-Tonifying and GV Strengthening Decoction (益肾强督汤) prescribed.
