踝肱指数与糖尿病周围神经病变及中医证候积分的相关性

目的：探讨踝肱指数（ABI）与糖尿病周围神经病变及中医证候积分的相关性。方法：选取我院内分泌科收治辩证以气阴两虚 为证型的糖尿病患者66 例，根据踝肱指数实验将患者分为ABI降低组（0.9>ABI>0.5）和ABI 正常组(1.4>ABI>0.9)。记录患者神 经病变症状尼龙丝检查以及中医症候评分，分析ABI与糖尿病周围神经病变及中医证候积分的相关性。结果：ABI降低组的糖尿 病周围神经病变的患病率高于ABI正常组（P<0.05）。ABI 降低组发麻、针刺感症状的发生率高于ABI 正常组，且有统计学差异 （P<0.05）。ABI降低组10 g尼龙丝检查异常者多于ABI正常组，差异显著（P<0.05）。ABI降低组的感觉振动阈值高于ABI正常组 （P<0.05）。ABI数值与中医证候积分呈负向直线相关（P<0.05）。结论：糖尿病患者ABI数值与糖尿病周围神经病变和中医证候积 分具有相关性。     

康复运动对冠脉支架植入术后患者相关因素的影响

目的：研究心脏康复运动对冠脉支架植入术后患者血脂、血糖、体重指数及生活质量的影响。方法：对实施冠脉支架植入术的 146例患者进行比较分析，根据随机原则分为试验组76 例及对照组70 例。对照组患者给予常规的健康教育及冠心病二级预防指 导，给予定期随访。试验组患者在此基础上给予规律的康复运动指导。经过6 个月随访，比较两组患者血脂、HbA1C、体重指数及 生活质量情况。结果：试验组患者通过为期6 个月的规律的心脏康复运动指导，其血脂、HbA1C等冠心病危险因素控制情况优于 对照组，差异有统计学意义(P<0.05)。同时，6个月后，试验组康复运动六月后sF 量表各项评分与对照组同期比较，差异均有统计 学意义(P<0.05)。结论：规范的心脏康复运动指导能够有效改善冠脉支架植入术后患者血脂、血糖情况，提高患者生活质量。     

Analyses of landuse change impacts on catchment runoff using different time indicators based on SWAT model

Previous researches mainly focused on the runoff responses to landuse change based on annual, seasonal or monthly time scales, there are few studies based on daily scale. We conducted a comprehensive investigation into runoff responses on the daily scale as well as annual and monthly time scales using SWAT, and compared the impacts of time scales with different time indicators quantitatively. Jinjiang, a coastal catchment of southeast China with a humid sub-tropical climate, was used for simulations. A calibrated SWAT model produced satisfactory reproduction of annual, monthly and daily runoff processes over a nine-year (2002–2010) period at three gauging stations. Runoff was then simulated and compared using the same meteorological input but two different landuse scenarios (1985 and 2006, with reduced forest and increased cropland and urbanized area). The results showed varying change in runoff among three time scales and three catchments. The annual runoff had the smallest increase between two scenarios, monthly runoffs had medium rates (increasing in all months except October–November), and daily runoff had the largest rates with the increase in flood peaks but decrease in drought flows, because of the variable influence on interception/evapotranspiration loss, percolation and antecedent soil water storage. Indicators of different time scales (annual runoff, monthly runoff, maximum 1-day and 5-day flood runoff, minimum 1-day and 7-day runoff) proved appropriate for analysing landuse change impacts.
