全自动颈椎牵引器的临床应用

为观察全自动颈椎牵引器对治疗神经根型颈椎病的临床疗效，为临床合理应用提供依据。选择神经根型颈椎病患者60例，随机分为治疗组和对照组各30例，分别用该牵引器和普通四头带坐位牵引，牵引重量为5kg，牵引角度为前屈100，牵引时间为30分钟，每天1次，牵引2周。牵引前和牵引2周摄颈椎侧住片，量出C2—C7各椎间隙之间最大距离。两组比较，并对每组病人牵引前后进行症状评分比较。结果显示，两组各椎间隙牵引前后的变化均有极显著性的差异（P〈0．01）；两组之间比较有显著性差异（P〈0．05）；两组之间症状评分比较有极显著性差异（P〈0．01）。表明全自动颈椎牵引器治疗神经根型颈椎病有良好效果，疗效优于普通四头带牵引。     

McKenzie法结合推拿、牵引疗法治疗神经根型颈椎病的临床观察

目的探讨改良直丝弓一步滑动法关闭拔牙间隙的临床疗效。方法选择2006年7月至2008年1月到广西梧州市红十字会医院口腔科就诊的安氏I类双颌前突患者共20例,按就诊顺序将患者牙弓的4个区左右配对随机分组,单数患者牙弓的左上区和左下区为试验组,右上区和右下区为对照组;双数患者分组与之相反。试验组采用颊侧镍钛丝拉簧加舌侧弹性牵引关闭间隙,对照组采用颊侧镍钛丝拉簧牵引关闭间隙。测量间隙关闭量后进行统计学分析。结果试验组间隙关闭速度为每月(0.98±0.03)mm,对照组为每月(0.79±0.03)mm,两组间比较差异有统计学意义(P<0.01);两组尖牙牙根和牙槽骨治疗前后变化比较差异均无统计学意义。结论应用改良直丝弓一步滑动法关闭拔牙间隙,速度快,费用少、临床疗效良好,具有很好的推广应用前景。     

镍钛丝拉簧加舌侧弹性牵引关闭拔牙间隙的临床研究

目的研究镍钛丝拉簧加舌侧弹性牵引关闭拔牙间隙的临床效果。方法选择安氏Ⅰ类双颌前突22例共88象限区,采用镍钛拉簧加舌侧弹性牵引关闭间隙。结果经过治疗最后纳入统计的80个区,关闭间隙速度平均0.99 mm/月,治疗前后尖牙牙根及牙槽骨高度吸收轻微。结论镍钛丝拉簧加舌侧弹性牵引关闭拔牙间隙速度快且是安全的。     

血吸虫病重疫区以机代牛意向调查多重对应分析

目的了解湖北省血吸虫病重流行区养牛户对以机代牛的意向以及影响其意向的有关因素,为政府决策和促进以机代牛提出科学的应对策略与措施。方法选择湖北省22个血吸虫病重流行县(市、区)。每个县(市、区)按血吸虫病流行类型、种植结构等选择9个村400户养牛户的户主为调查对象,采用问卷调查表进行调查,并采用χ2检验和多重对应分析等对调查数据进行分析。结果共调查8239户养牛户,愿意淘汰牛的有4656户,占56.51%;影响养牛户意愿的主要因素包括所在村疫区类型、户主年龄、耕地分布结构、售牛及配种收入、家庭主要收入来源和年人均纯收入、家庭内是否有农耕机械、现有农机服务情况、养牛的主要原因等,其中户主年龄、耕地分布结构、人均收入、村疫区类型等关系最为密切。结论以机代牛是现阶段控制血吸虫病流行的最有效手段之一。目前多数养牛户持支持态度,但其广泛开展受社会经济发展水平、地势地貌、养牛户主年龄、农机服务水平、农业种植结构、农村基础设施等诸多因素的影响,因此必须科学布置,谨慎实施。

Exposure to cold and draught, alcohol consumption, and the NS-phenotype are associated with chronic bronchitis: an epidemiological investigation of 3387 men aged 53-75 years: the Copenhagen Male Study

OBJECTIVES—This study was performed to estimate the strength of association between chronic bronchitis and lifetime exposure to occupational factors, current lifestyle, and the NS-phenotype in the MNS blood group among middle aged and elderly men.
METHODS—The study was carried out within the frameworks of the Copenhagen Male Study. Of 3387 men 3331 men with a mean age of 63 (range 53-75) years could be classified by prevalence of chronic bronchitis. As well as the completion of a large questionnaire on health, lifestyle, and working conditions, all participants had a thorough examination, including measurements of height and weight and blood pressure and a venous blood sample was taken for the measurement of serum cotinine and MNS typing; 16.5% of the men had the NS-phenotype. Chronic bronchitis was defined as cough and phlegm lasting 3 months or more for at least 2 years; 14.6% had chronic bronchitis.
RESULTS—Smoking and smoke inhalation were the factors most strongly associated with prevalence of chronic bronchitis. There were three major new findings: (a) long term (>5 years) occupational exposure to cold and draught was associated with a significantly increased prevalence of chronic bronchitis; compared with others, and adjusted for confounders, the odds ratio (OR) with 95% confidence interval (95% CI) was 1.4 (1.1 to 1.7), p=0.004; (b) a significant J shaped association existed between alcohol use and bronchitis, p<0.001, with the lowest prevalence found among moderate users; (c) a significant gene by environment association existed between smoking and the NS-phenotype in the MNS blood group; only among smokers was the NS-phenotype associated with a significantly decreased risk of chronic bronchitis, OR 0.67 (0.47-0.97), p=0.02. Other well known associations between dust, fumes, and even exposure to solvents and bronchitis were confirmed.
CONCLUSION—The results emphasise the multifactorial nature of chronic bronchitis, and show some hitherto unrecognised associations between cold and draught exposure, alcohol consumption, and the NS-phenotype and chronic bronchitis.
