目的 观察自拟温润方治疗风寒袭肺型急性咳嗽病的临床疗效。方法 64例风寒袭肺型急性咳嗽病患者,随机分为对照组(31例)和治疗组(33例)。对照组患者给予复方甘草口服溶液治疗,治疗组患者给予温润方治疗。比较两组患者治疗前和治疗3、6 d后的中医症状评分以及临床疗效。结果 治疗3、6 d后,两组患者咳嗽、咯痰、恶风、咽痒、鼻塞、流涕、鼻干、口干咽燥症状评分均低于治疗前,差异均具有统计学意义(P<0.05)。治疗组患者治疗3 d后咳嗽、咽痒、鼻干、口干咽燥症状评分分别为(2.18±0.98)、(1.15±0.81)、(0.60±0.61)、(0.81±0.71)分,均低于对照组的(3.04±1.62)、(1.68±0.96)、(0.96±0.67)、(1.37±0.86)分,差异均具有统计学意义(P<0.05);治疗组患者治疗6 d后咳嗽、咽痒、鼻干、口干咽燥症状评分分别为(0.54±0.51)、(0.42±0.48)、(0.40±0.46)、(0.47±0.51)分,均低于对照组的(1.12±0.76)、(1.11±0.98)、(0.88±0.98)、(1.01±0.92)分,差异均具有统计学意义(P<0.05)。两组患者治疗3、6 d后咯痰、恶风、鼻塞、流涕症状评分比较,差异无统计学意义(P>0.05)。治疗3 d后,治疗组治疗总有效率90.9%高于对照组的71.0%,差异具有统计学意义(P<0.05)。治疗6 d后,治疗组患者治疗总有效率93.9%与对照组的90.3%比较,差异无统计学意义(P>0.05)。结论 在风寒袭肺型急性咳嗽病治疗中,温润方在缓解咳嗽以及部分次症方面明显优于复方甘草口服溶液,起效更快。     

成人腰椎峡部裂型滑脱症的微创治疗

Objective To investigate the clinical experiences and technical skills of adult isthmic spondylolisthesis. Methods Twenty-one patients with adult isthmic spondylolisthesis underwent minimally invasive surgery. There were 12 men and 9 women, with the mean age of 51.7 years. Isthmic spondylolisthe-sis occurred at the L4.5 in 7 patients, and at the L5S1 in 14 patients. According to Meyerding classification, 13 cases were of Grade Ⅰ, 7 of Grade Ⅱ, 1 of Grade Ⅲ. Under general anesthesia, guiding by fluoroscopy, the surgeries performed minimally invasive microendoscopic(METRx) techniques for posterior decompression, interbody cage fusion and novel Sextant-R percutaneous pedicle screw techniques for deformity reduction and fixation. Results Seventeen cases were followed up 1 year postoperatively. The average low back pain VAS reduced from preoperative 6.0±2.6 to postoperative 2.9±2.5. The average leg pain VAS decreased from preoperative 6.7±3.3 to postoperative 2.8±1.6. The average ODI decreased from preoperative 44.3% to post-operative 27.1%. The Nakai good and excellent rate was 90%. The mean operative time 170 min, blood loss 160 ml, and postoperative stay in bed 7.5 d. The sagittal spondylolisthesis rate significantly decreased from preoperative 35.5%±2.5% to postoperative 8.3%±7.5%. The lordotic angle from preoperative 11.5°±1.7° in-creased to postoperative 16.8°±9.5°; the intervertebral disc height from preoperative (5.4±2.5) mm increased to postoperative (9.1±3.0) mm. According to Lenke judgement for fusion, complete fusion rate was 76%, in-complete fusion rate was 12%, nonfusion rate was 12%. Conclusion The minimally invasive microendo-scopic (METRx) assisted with a novel Sextant-R percutaneous pedicle screw systems for deformity reduction and fixation to treat adult isthmic spondylolisthesis, is not only a minimally invasive and safe surgical tech-nique, also an effective treatment for deformity reduction and fixation.     

QCT骨密度测量的质量控制及意义

目的目前国内对QCT骨密度测量的质量控制研究较少，本文介绍了QCT骨密度测量的准确度、精密度试验方法和意义。方法使用东芝CT机自带体模和软件为测量工具，测量四川大学华西骨质疏松研究中心等研制的QCT骨体模（称四川体模）的骨密度值。四川体模固定于15cm深的水浴中模拟人体腰椎，东芝体模置于水浴容器与扫描床面之间，按照人腰椎QCT骨密度测量相同的条件和方法进行操作，每日1次对测量体模连续测量25日，计算SD和CV，分别以25次测量125d25次测量／1d基线作3m的shewhart图。结果测量四川体模从小到大三管骨密度分别的准确度误差为-60．4％、-39．1％和-13．6％，其分别的校正系数为2．69、1．64、1．15，相关系数为0．9966，回归方程Y=35．6＋0．958X（X为测量骨密度，Y为校正后骨密度）。本型QCT机骨密度测量的25次／1d及25次，25d精密度误差分别为1．25～5．54％和1．98～7．87％。25次125d的精密度误差要大于25次，d，显示机器一日内精密度误差变化小，随时间延长其变化增大。以25次125d的结果为基线绘制的shewhart图优于25次/d。结论一切QCT骨密度测量都应进行质量控制，准确度必须予以校正，精密度试验应在此基础上进行。这样结果才真实、科学、可靠并具有可比性。
