孙远征教授针刺治疗痛证的临床经验

疼痛在生活及临床诊疗中普遍存在,针刺在痛证的治疗上表现多维度调控优势。孙远征教授从事临床针刺工作40余载,其认为痛证所发,内因于神,外责于经;以“神”为本,以“经络辨证”为纲,审机辨治,总结出“察痛于神,宁心调脑,神安痛减;辨痛于经,止痛求远,抑痛于动;诊痛浅深,适施其法,针至病所”的治痛理念;察痛缓急,灵活运用调神针刺法、循经远取动法及背部阳经透刺等方法,治痛效果显著。

遥感估算植被覆盖度的角度效应分析

植被覆盖度是植被在地面的垂直投影面积占统计区总面积的百分比.由于植被反射的二向性特性,不同角度估算的植被覆盖度原则上不可比,另外,不同观测角度对应像元不同的采样面积,对于非均一地表这种面积差异引起的角度效应也非常显著.本文除了考虑植被的二向性反射,还重点模拟分析了由于像元的采样面积差异引起的角度效应及其带来的植被覆盖度估算误差.模拟结果表明:相比天顶观测,在倾斜40°观测时,对于作物和裸土混合,由于面积误差带来的红光波段反射率差异已高达56%,同时引起的植被覆盖度估算误差达到23%,因此研究植被覆盖度的角度效应问题很有必要.

孙远征教授针灸治疗病毒感染后嗅觉障碍经验

[目的]总结孙远征教授治疗病毒感染后嗅觉障碍的临床经验。[方法]通过跟师学习,总结病毒感染后嗅觉障碍的病因病机及发病机制,分析孙师对本病的辨治思路,明病位、定病经,辨证选穴遣针,以及孙师治疗本病的独到之处,并通过病案加以验证。[结果]孙师认为,本病病机为正气内伐而虚邪贼风趁势侵袭,卫表被郁,肺失宣降,壅塞清道,经脉不畅,鼻失香臭,终发此病。病毒感染后,临床感冒症状虽已缓解,但人体正气虚弱,加之病毒易侵袭嗅上皮或嗅神经,致使神经传导减弱、中断或消失。治疗以疏通经络气机、明确病变脏腑为法,采取“头针总调,局部疏通,远端配合”的整体治法,注重保健要穴的重要性。文中所附为病毒感染后嗅觉障碍病案,运用整体治法,辨为失嗅,治以补益肺气、通鼻化痰,临床疗效显著,用针少而精,随访半年未复发。[结论]孙师运用“头针总调,局部疏通,远端配合”的整体治法治疗病毒感染后嗅觉障碍,体现了针刺治疗本病的优势所在,临床疗效较好,值得推广应用。

孙远征教授运用循经远取动法治疗痛症举隅

痛症是临床上较为常见的症状之一,往往影响患者的工作与生活,近年来得到了人们的广泛重视。孙远征教授在明辨痛症病因、针灸镇痛机理的基础上,根据传统经络循行及疼痛部位的特点,结合"标本根结"理论,遵循"经脉所过,主治所及"和"上病下治,下病上治"的选穴原则,同时配合运动疗法,提出了循经远取动法治疗痛症。尤其在治疗软组织痛症方面,疗效显著,值得临床上加以总结应用。

孙远征教授针刺治疗原发性面肌痉挛经验撷要

[目的]总结孙远征教授针刺治疗原发性面肌痉挛的临床经验。[方法]通过临床跟师学习,从孙师对本病的认识及治疗特色等方面进行阐述,分析孙师对本病的辨治思路,并通过病案举例加以验证。[结果]孙师认为,本病实质为正虚风动,与情志因素关系密切,风为导致痉挛发病最主要的致病因素,情志不调为导致疾病加重的诱发因素,将其分为内风、外风两种致病模式。孙师认为本病病位在面部经筋,与面部经气受损有关,经络之气不通,局部气血流通不畅,故发为本病。孙师治疗本病有以下特色,重视“调神”,神安形止;基于“缪刺”,调衡阴阳;揿针留置,长效止痉;明辨经络,辨证遣针,以此四法针刺辨治原发性面肌痉挛。文中所附一例原发性面肌痉挛病案,观其舌苔脉象及症状表现,辨为面风,阴虚风动型,治以疏肝养阴、熄风止痉,以调神法、缪刺法、揿针法、远取法联合治疗,收效甚佳,随访半年未复发。[结论]孙师临床辨治原发性面肌痉挛,以形神关系为基础,以明辨经络、定病经、辨证遣针为原则,治疗时调神、缪刺、揿针、远取相结合,体现了针刺治疗的优势所在,拓宽了该病的诊治思路,值得学习和推广。
