经鼻持续气道正压通气治疗对OSAHS患者胰岛素抵抗的影响

目的探讨经鼻持续气道正压通气(nCPAP)对阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者胰岛素抵抗(IR)的治疗价值。方法接受多导睡眠监测的中重度OSAHS患者115例,其中65例接受综合干预治疗6个月为对照组,50例在综合干预治疗的同时接受nCPAP治疗为实验组。在治疗前后分别测定体重指数(BMI)、呼吸暂停低通气指数(AHI)、最低血氧饱和度(miniSpO2)、空腹血糖值和空腹胰岛素值,并计算其胰岛素敏感指数(ISI)。结果治疗前实验组ISI为-4.75±0.44,对照组为-4.78±0.37,两者差异无显著性意义(t=0.021,P>0.05);治疗后实验组(-4.19±028)较对照组(-4.52±0.47)明显升高(t=4.408,P<0.001)。两组ISI与BMI均呈负相关(分别为r=-0.451,P<0.01;r=-0.422,P<0.01),ISI与AHI均呈负相关(分别为r=-0.866,P<0.001;r=-0.829,P<0.001),ISI与miniSpO2均呈正相关(分别为r=0.771,P<0.001;r=0.809;P<0.001)。结论nCPAP能明显改善OSAHS患者的IR。MBI、AHI和miniSpO2可能是nCPAP治疗OSAHS患者IR的有效预测指标。     

中德患者中医证候学比较研究

通过对中德患者舌诊、脉诊及中医证候的比较研究显示：德国患者中医辨证多偏气虚和阳虚的证型，中国患者则较多偏气虚和阴虚的证型，舌象和脉象也存在显著性差异。研究认为，传统医学应该重视理论和实践的总结，重视医学教育和经验的继承与创新，重视临床技术和辨证论治的实际传授。

咳嗽“死脉”在肺癌预后中的临床应用

目的:探讨咳嗽“死脉”在肺癌预后中的临床应用.方法:通过查阅古籍,总结、归纳“死脉”的种类和其临床应用.结果:古医家论述的“死脉”之“死”是病重、难治的脉象,即中医古书论述的危重期,“死脉”和患者死亡没有必然的联系,但“死脉”可以作为肺癌预后的判断标准之一.结论:咳嗽“死脉”对肺癌预后有一定的指导作用.     

Change of bilateral difference in radial artery pulse morphology with one-side arm movement

Previous studies have demonstrated that the compliance of peripheral artery changes with arm movement. This study aimed to quantify the bilateral difference in radial artery pulse morphology with one-side arm movement. Twenty-four healthy subjects were recruited. Radial artery pulses were synchronously recorded from both arms, with one arm (left or right) at five different positions (90°, 45°, 0°, −45° and −90°) and the other arm at horizontal level (0°) as reference. Two types of indices of arterial pulse morphology were derived from the normalized arterial pulse signals: the waveform width corresponding to the 50%, 60% and 70% pulse amplitude (W₅₀, W₆₀, W₇₀) and the total area of normalized pulse waveform (A_pulse). No matter whether the moving arm was left or right arm, when compared with the other side reference arm, all the waveform widths decreased with arm moving from 90°, 45°, 0°, −45°, and −90°. The bilateral difference of W₅₀, W₆₀ and W₇₀ with the moving arm (either left or right) at 90°, 45° were significantly positive (both p < 0.01) and significantly negative at −90° (both p < 0.05). Meanwhile, no matter whether the moving arm is left or right, A_pulse decreased with arm moving from 90°, 45°, 0°, −45°, and −90°. The bilateral difference of A_pulse with the left moving arm were significantly positive at 45°, 90° (both p < 0.05). Meanwhile, the bilateral difference of A_pulse from the moving right arm was significantly positive at 90° and significantly negative at −45° and −90° (all p < 0.05). In summary, this study quantified the bilateral arterial pulse morphology between arteries with different compliances induced by a simple arm positioning procedure.     

Controlled,randomized study evaluating the effects of treating cellulite with AWT®/EPAT®

Abstract

Introduction: Cellulite affects 95% of women and can lead to negative consequences. Objective: To demonstrate the efficacy and safety of acoustic wave therapy (AWT®) using extracorporeal pulse activation technology (EPAT®) to manage cellulite. Methods: Twenty-five women were included in the study and treated with AWT®. Six AWT® treatment sessions were performed over the course of 4 weeks. Three thousand pulses were applied to an area measuring approximately 10 × 15 cm on the thigh. The treatment was performed using the D-ACTOR® 200 by STORZ MEDICAL AG (Tägerwilen, Switzerland). Follow-up visits were performed 1 week and 12 weeks after treatment. Changes in the skin structure were evaluated using the DermaTOP System (Eotech, Paris, France). Skin elasticity measurements were performed using the DermaLab Device (Cortex Technology, Hadsund, Denmark). Results: The difference between treated and untreated legs was statistically significant with regard to depressions, elevations, roughness and elasticity after the first follow-up visit. Conclusion: The study showed that the AWT/EPAT treatment using the D-ACTOR 200 appears to be a safe and effective treatment alternative for the temporary improvement in the appearance of cellulite.     

Fractional Factorial Design Study on the Performance of GAC-Enhanced Electrocoagulation Process Involved in Color Removal from Dye Solutions

The aim of this study was to determine the effects of main factors and interactions on the color removal performance from dye solutions using the electrocoagulation process enhanced by adsorption on Granular Activated Carbon (GAC). In this study, a mathematical approach was conducted using a two-level fractional factorial design (FFD) for a given dye solution. Three textile dyes: Acid Blue 74, Basic Red 1, and Reactive Black 5 were used. Experimental factors used and their respective levels were: current density (2.73 or 27.32 A/m²), initial pH of aqueous dye solution (3 or 9), electrocoagulation time (20 or 180 min), GAC dose (0.1 or 0.5 g/L), support electrolyte (2 or 50 mM), initial dye concentration (0.05 or 0.25 g/L) and current type (Direct Current—DC or Alternative Pulsed Current—APC). GAC-enhanced electrocoagulation performance was analyzed statistically in terms of removal efficiency, electrical energy, and electrode material consumptions, using modeling polynomial equations. The statistical significance of GAC dose level on the performance of GAC enhanced electrocoagulation and the experimental conditions that favor the process operation of electrocoagulation in APC regime were determined. The local optimal experimental conditions were established using a multi-objective desirability function method.
