Objective To study the temperature changes around metal in ultrashort wave electric-field and it's influence factors.Methods Medical ultrashort wave therapeutic instrument was used and output switen was set at the 1 st grade.After tuning, one end of metal object was placed into 0.2ml water contained in a plastic tube ( with a length of 2cm and diameter of 2mm).Temperature changes of water around metal in different conditions were measured by digital thermometer.In experiments, several different conditions were studied, such as the length of metal, the vertical distance between metal and electrodes, the location of metal ultrashort electric field and the action duration of ultrashort wave.Results Under the same condition, when the prolate axis of metal paralleled to electrodes and the real lengths of metal outside of electric field were 10cm, 20cm, 30cm, 50cm, 70cm, 90cm, water temperatures around metal rose 4.37, 8.30,18.00, 20.64, 32.92 and 38.96℃, respectively; when the prolate axis of metal paralleled to electrodes and the verticaldistances between metal and one electrode were 1.5, 3.0, 4.5 and 6.Ocm, water temperatures around metal rose 66.03,49.37, 14.80 and 0.87℃, respectively; when the prolate axis of metal was vertical to electrodes and the distanees between one end of metal and electrodes were 5, 9 and 15cm, water temperature around metal rose 56.10,26.64 and11.07℃, respectively; when the vertical distances between metal and the electrode edge were 0,5,10,15cm, water temperatures around metal rose 25.32 , 10.26 ,2.88 and 1.53℃, respectively;when the lengths of metal with a fixed-length,the included real length in electric field, were 20, 10 and 0cm, water temperatures around metal rose 2.84 , 4.04 and7.30℃ , respectively.Under the same condition, the action duration of ultrashort wave were changed to be 5 and 10min,water temperatures around metal rose 24.90 and 39.07℃, respectively.Conclusion This study show that the water temperature rising around metal will be relatively small when:( 1 ) the real length of metal is short ; ( 2 ) the prolate axis of metal parallels to electrodes and is placed in the middle area between two electrodes;(3)the distance between two electrodes increase and the action duration is short;(4)the overall length of metal is contained in electric field between electrodes,or the metal is kept away from electrodes edges.

超短波对脊髓损伤后内源性神经干细胞存活和分化的影响

目的:观察脊髓损伤后内源性神经干细胞的存活和分化的变化,并且观察超短波对这一变化的影响。方法:用46只SD大鼠,被随机分成3组:假手术组,只暴露硬脊膜,不给予打击;对照组,给予Allen打击,并不做任何处理;干预组,给予Allen打击,并在SCI后24h开始给予小剂量超短波(11W)干预,每日1次7min直至取材前。大鼠的运动功能用BBB评分进行评定,大鼠取材后分别对组织进行横向切片,分别进行HE和免疫荧光染色,来检测脊髓形态和Nesin、GFAP、Neu N在组织内的表达部位和表达量,以观察内源性神经干细胞在脊髓损伤后并超短波干预后存活和分化为星形胶质细胞的情况。结果:(1)BBB评分显示,3天后后肢功能评分逐渐恢复。干预组与对照组相比,3天、5天和7天的BBB评分并没有显著的差异,直到14天,干预组的后肢功能BBB评分高于对照组,并且差异显著(P<0.05);(2)Nestin、GFAP、Neu N免疫荧光染色:在脊髓中央管,Nestin阳性细胞在损伤后第3天表达最多,并且随着损伤后时间的推迟,Nestin阳性细胞的表达量却是逐渐减弱的,到第14天表达水平与假手术组相当。GF...     

颈动脉粥样硬化斑块与相关因素的探讨

目的探讨颈动脉硬化斑块与其相关因素与脑梗塞发生的相关影响。方法对177例患者行颈动脉超声检查,根据颈动脉硬化斑是否存在,分为斑块组和无斑块对照组。同期CT观察颈内动脉供血区是否发生脑梗塞。生化检查血糖、胆固醇、甘油三酯、高密度脂蛋白、低密度脂蛋白。并将高血压患者分为I级、Ⅱ级、Ⅲ级。结果颈动脉斑块分布：两侧同时存在比例最高,达50％;仅单侧分布：左侧高于右侧,分别为33％、17％。颈动脉斑块组脑梗塞的发生率为79．54％;非动脉斑块组脑梗塞发生率为29．2％,低于斑块组（P〈0．05）。双侧颈动脉斑块中,发生双侧脑梗塞比例最高,左侧次之,右侧最低;左侧颈动脉斑块中,发生左侧脑梗塞比例最高,双侧次之,右侧最低;右侧颈动脉斑块中,发生右侧脑梗塞比例最高,双侧次之,左侧最低。颈动脉硬化斑块组的年龄、血糖均较无斑块组高;发生高血压比例高,且随着高血压分级的增加,斑块发生率也逐步提高,Ⅲ级高血压及脑梗塞的发生率高于无斑块对照组（P〈0．01）。而颈动脉斑块与血脂则相关性不大。结论颈动脉硬化斑块与年龄、血糖、高血压密切相关,发生脑梗塞的几率明显增加。与血脂相比,血糖增高和高血压对动脉硬化斑块的形成起到更重要的作用。

超短波早期治疗激素性股骨头缺血性坏死的实验研究

目的采用马血清、激素联合应用诱导股骨头坏死模型，观察超短波早期干预治疗的效果。方法对新西兰大白兔联合应用马血清、激素造模处理，30只大白兔随机分成对照组、模型组和超短波组，各组分别检测血栓素A2(thromboxane A2，TXA2)、前列环素(prostaglandin，PGI2)和血脂(triglyceride，TG)、胆固醇(total cholestrol，TCh)及血液流变学指标，并进行分析比较。结果10周后模型组产生股骨头缺血性骨细胞死亡，骨髓细胞减少，出现高粘滞血症、高脂血症和TXA2-PGI2平衡失调，导致血栓形成，造成股骨头缺血性坏死。、而超短波组进行超短波干预治疗后，血液循环加快，血脂水平降低，血液粘度降低，血小板活性下降，TXA2-PGI2平衡得以恢复，从而保护血管内皮，防止血栓形成．结论上述各项指标的检测是激素性股骨头缺血性坏死较为敏感的指标，超短波早期干预治疗可能成为防治激素性股骨头缺血性坏死发生的一种新疗法。
