练“回春术”提高性功能

我曾经在每次房事后，头昏脑胀，全身乏力，做事和走路都无精打来，对练功也非常不利，原已练成的气感变得微乎其微。后来有本得到通过呼吸来增强性功能的道家回春术，习练一个时期后。再未发生以上现象，房事后，全身轻松愉悦，练起功来气感不减。练功之人最忌精气不断流失，而抑制性欲、杜绝房事又不现实．对此回春术提供了较理想的流转渠道令将此术简介于后，以借花献佛坐立姿均可，全身放松，采用腹式呼吸法，慢慢吸起来，又慢慢大口吐出、直到感觉下腹部发生热力。然后在呼吸同时，做提肛动作，吸时提肛，呼时松肛，并用意念配合将气送…     

变异型心绞痛诱发严重心律失常二例

变异型心绞痛（ＶＡ）临床上并非少见，但ＶＡ诱发严重心律失常之报道尚不多见。作者遇见２例，现报道如下。１临床资料例１，男性，６０岁。因反复发作心前区疼痛２个月入院。高血压病史１年。查体：血压１５０／９０ｍｍＨｇ（１ｍｍＨｇ＝０．１３３ｋＰａ），心界不大...     

经食管超声心动图探查胸主动脉粥样梗化对冠状动脉粥样硬化的预测价值

本文采用经食管超声心动图技术观察了６４例行冠脉造影患者的胸主动脉粥样硬化病变。结果表明４２例阳性患者中ＴＥＥ发现３６例有胸主动脉粥样斑块，而２２例阴性中仅２例存在斑块，二者相比有高度显著性差异（Ｐ＜０．００１）。以冠脉造影结果为金标准，斑块为预测冠心病的指标，其敏感性８５．７％，特异性９０．９％。冠脉造影阳性组的胸主动脉粥样硬化病变多为Ⅱ、Ⅲ级，而阴性组多为０、Ⅰ级，二组差异显著（Ｐ＜０．００５）。多支冠脉病变组胸主动脉粥样梗化程度较单支组严重（Ｐ＜０．０１），但正常组和狭窄＜５０％组之间无显著差异（Ｐ＞０．０５）。本研究认为胸主动脉粥样斑块能预报有临床意义的冠状动脉狭窄，胸主动脉可作为了解冠状动脉粥样硬化程度的窗口     

经皮冠状动脉腔内成形术中反复血流阻断对心肌缺血预适应 …

目的：评价经皮冠状动脉腔内成形术（ＰＴＣＡ）中短时、反犁的血流阻断－再灌注是具有抗急性缺血预适应现象及缺血相关性心律失常的作用。方法：连续观察１３８例住院接受ＰＴＣＡ术的冠状动脉粥样经性心脏病患者患者术前扩术中的心电图、心率和血压等指标变化。结果：（１）３３例（２３．９％）患者术中出现室性早搏（ＶＥ）３８例次，其中３０例于首次球囊扩张时了ＶＥ，９例记录到 ＶＥ二联中或对ＶＥ；８例于再次球囊扩张时出     

阵发性室上性心动过速的拳击复律(附21例24例次报告)

阵发性室上性心动过速(PSVT)为临床上常见的快速型心律失常之一,终止其发作视为主要治疗目的。转复PSVT的方法较多,但其疗效不一,且均有一定的副作用。心前区拳击治疗心动过速虽为较古老的方法,但使用该法转复较为人宗病例之PSVT国内外甚少报道。作者近来试用该法治疗21例24例次PSVT,取得了较为满意的复律效果,现报道如下。     

医疗保险圈存机及电脑查询触摸屏消毒

随着医疗保险覆盖面的扩大,参保人员不断增加,门诊医疗保险圈存机及电脑查询触摸屏的使用频率越来越高。本医院日均门诊量达千余人,医疗保险病人约占44%,许多人在刷卡交费前后都要查询,甚至有些非就诊人群也前来查询,造成医疗保险圈存机和电脑查询触摸屏受细菌污染严重。我们针     

实时荧光定量PCR非特异性分析

聚合酶链反应(polymerase chain reaction,PCR)因灵敏度高、操作简便在各个领域得到了广泛的应用。然而,伴随其高灵敏度存在的非特异性问题在一定程度上限制了其应用。不同于普通检测方法,该技术的非特异性问题主要由可以指数扩增的引物二聚体(primer dimer,PD)引起。对此,引物设计时使用的中部同序引物对可以从根本上避免PD的产生,从而解决由其引起的非特异性问题。该文从PCR的发展和本质、PCR非特异性产生的原因和应对策略等方面作一总结及分析。     

缝隙连接蛋白43在老年大鼠缺血性室性心律失常中的作用

Objective To investigate the expression of connexin43 ( Cx43 ) and effect of vagal nerve stimulation (VNS) on ventricular tachyarrhythmias during acute myocardial ischemia( MI )in aged rats. Methods Male Sprague-Dawley rats[Adult group ( ≤ 4 months) and Aged group ( ≥24 months)]:MI (n = 15 ):ligated left anterior descending coronary for 30 minutes; MI-vagal nerve stimulation(VNS) ( n = 15 ); MI-VNS-atropine (0. 5 mg/kg, n = 13 ); MI-VNS-carbenoxolone ( 10 mg/kg, n = 11 ); sham operation (SO, n = 10):without coronary ligation. Ventricular arrhythmias were monitored by an electrocardiogram. Cx43 protein expression was analyzed by Western blot. Results During the 30 minutes ligation,incidences of ventricular tachycardia (VT) and ventricular fibrillation(VF) in aged rats increased significantly compared to those of adult rats ( P ＜ 0. 05 ). VNS did not affect the occurrence of VT and VF ( both P ＞ 0.05 ); however, VNS suppressed the occurrence of irreversible VF ( P ＜ 0. 05 ); both atropine and carbenoxolone ( a gap junction inhibitor) could abolish the effect of VNS on ischemia-induced irreversible VF ( both P ＜0. 05). Ischemia did not result in changes of total Cx43 amount in adult and aged rats compared to that of SO group,respectively. The amount of nonphosphorylated Cx43 was increased markedly in adult and aged rats compared to that of SO group,respectively.Cx43 dephosphorylation induced by ischemia was significantly suppressed by VNS in adult and aged rats( P ＜0. 05 ). However,the amount of total Cx43 of SO group in aged rats was significantly decreased by 50% compared to that of SO group in adult rats ( P ＜ 0. 05 ). Conclusion The present study suggested that the incidence of ischemia-induced ventricular tachyarrhythmias increased markedly and the anti-arrhythmic effect of VNS was decreased significantly in aged rats, which may be associated with reduction of Cx43 protein of ventricle in aged rats.
