1、手三阴手三阴Differentiation of syndromes(4)Differentiation of syndromes according to the pathological changes of zang-fu organsvTCM was not founded on the basis of precise anatomy.Internal organs,more accurately called zang-fu organs,actually refer to the major functional systems of the human body.vIn the

2、 progress of TCM,no patho-anatomy was studied.vTherefore,the pathological changes of the internal organs should not be misunderstood as the patho-anatomical changes of organs and tissues on which the western diagnosis of diseases is based.vThey are the pathophysiological changes of the functional sy

3、stems recognized in the light of tradition Chinese medical theories.vDiagnosing pathological changes of the internal(zang-fu)organs is the most important component of differentiation of syndromes,for it is often a comprehensive analysis of the pathogenesis in a given cases,vincluding its location,na

16、ng of the tongue a floating,tense pulse 3.invasion of the lungs by wind-cold（3）vSyndrome analysis:Coughing the lungs are invaded by wind-cold.Disturbance of the normal flow of lung qi leads to coughing,and the sputum is thin and whitish because the pathogenic cold impeding the normal distribution of

17、 fluid in the lungs produces phlegm,but does not condense it.The nose is the“specific opening”of the lungs.Disturbance of the dispersing function of the lungs results in a stuffed-up nose with watery discharge.The lungs are also in charge of defensive qi,which resists the invading pathogens on the s

18、uperficial part of the body.3.invasion of the lungs by wind-cold（3）When defensive qi is restrained by exogenous pathogens,chills occur;and when defensive qi resists the pathogens,heat is generated.In addition,the pathogenic cold closes the pores.Therefore,there are chills with fever but no sweating.

19、In comparison with pathogenic heat,pathogenic cold only induces mild fever while pathogenic heat may give rise to high fever.Since the pathogenic factor has not been transmitted into the interior,the tongue coating is still normal.A floating,tense pulse indicates superficial affection by cold3.invas

20、ion of the lungs by wind-cold（3）vThis syndrome is very similar to exterior cold syndrome(an exterior syndrome caused by wind-cold).The difference lies in the fact coughing is the chief symptom in this syndrome,while chills and fever are the main symptoms and coughing is mild or even absent.3.invasio

23、the tongue a rapid,floating pulse.4.invasion of the lungs by wind-heat（3）vSyndrome analysis:This syndrome is characterized by coughing and exterior syndrome of wind-heat.Invasion of the lungs by exogenous wind-heat impairs the cleansing and descending function of the lungs,thus causing coughing.By t

24、he action of heat,fluids in the lungs are condensed to phlegm which is thick and yellow.4.invasion of the lungs by wind-heat（3）Resistance of defensive qi against the invading wind-heat produces fever,and restraint of defensive qi by wind at the superficial portion of the body leads to mild aversion

25、to wind.Upward invasion of wind-heat causes sore throat,and impairment of body fluids by heat gives rise to thirst.Reddened tip and yellow coating of the tongue,and rapid,floating pulse indicate the presence of wind-heat.4.invasion of the lungs by wind-heat（3）vThe difference between this syndrome an

26、d exterior heat syndrome(an exterior syndrome caused by wind-heat)lies in the fact that the former is marked by coughing with expectoration of thick,yellow sputum,while in the latter coughing and expectoration is mild or even absent.Fever may be obvious in both syndromes.4.invasion of the lungs by w

27、ind-heat（4）vHerbal formula:5.Invasion of the lungs by heat(heat in the lungs)(1)vSummarize:vThis is often caused by direct invasion of the lungs by exogenous pathogenic heat or heat transformed from wind-cold or wind-heat when the latter enters the interior.It can be encountered in acute and chronic

28、 bronchitis,pneumonia and other respiratory infections in west medicine.5.Invasion of the lungs by heat(heat in the lungs)(2)vClinical manifestations:Coughing with expectoration of thick,yellow sputum,dyspnea with coarse breathing or flaring of the nares,high fever with thirst,restlessness,5.Invasio

30、nation with manifestations of interior heat.Accumulation of pathogenic heat in the lungs induces upward perversion of lung qi,resulting in coughing.The phlegm is formed due to condensation of fluids by heat,and so is thick and yellow.The pathogenic heat and phlegm impede the descending function of t

31、he lungs,giving rise to dyspnea with coarse breathing.5.Invasion of the lungs by heat(heat in the lungs)(3)The heat causes fever and impairs the body fluids,resulting in thirst,constipation and scanty,concentraded urine.The heat may also disturb the mind,causing restlessness.If blood vessels are inj

32、ured by heat,there is epistaxis or hemoptysis.A reddened tongue with a yellow coating and rapid pulse indicates heat in the interior.5.Invasion of the lungs by heat(heat in the lungs)(4)vHerbal formula:vMa xing shi gan tang(p264)v(decoction of ephedra,apricot seed,gypsum and licorice root)6.Invasion

33、 of the lungs by dryness(dryness of the lungs)(1)vSummarize:vThis syndrome can be encountered in patients with colds or bronchitis in dry seasons.6.Invasion of the lungs by dryness(dryness of the lungs)(2)vClinical manifestations:Dry cough or cough accompanied by scanty,sticky sputum difficult to ex

35、erized by dryness of the respiratory system,and at the early stage it may be accompanied by an exterior syndrome manifested by chills and fever.Dryness is apt to be transformed into heat or fire,which goes deep into the lungs or injures the blood vessels,thus causing chest pain and hemoptysis.In the

36、 early stage,when the pathogenic dryness stays chiefly in the upper portion of the lungs,only the tip of the tongue is reddened6.Invasion of the lungs by dryness(dryness of the lungs)(3)but when it goes deep into the lungs,the whole tongue is reddened.The white and yellow colors of the tongue coatin

37、g depend upon the intensity of the heat into which the pathogenic dryness has been transformed.The rapidity of the pulse also corresponds to the intensity of the heat6.Invasion of the lungs by dryness(dryness of the lungs)(3)vBoth invasion of the lungs by dryness and deficiency of lung yin are chara

38、cterized by dryness symptoms,but the former is acute while the latter is chronic.If there is any fever in the exogenous affection of the lungs by dryness,it only persists for a short period and is often accompanied by chills,but in deficiency of lung yin there is usually long-standing afternoon feve

42、uid in the large intestine makes the fecal mass hard and difficult to eliminate.The defecation is often infrequent-once every three or five days or even more than ten days.Yin deficiency causes dryness of the mouth and throat.Retention of the fecal mass in the large intestine may lead to upward flow

43、 of turbid qi,resulting in foul breath and dizziness.Deficiency of yin is accompanied by relative exuberance of yang,and hence the tongue is dry and reddened.Thready and hesitant pulse is due to insufficient fluid in the arteries.7.Deficiency of fluid in the large intestine(4)vHerbal formula:vZengye

44、 Chengqi Tang8.Sinking of spleen qi(1)vSummarize:vThis is also called“sinking of the qi of the middle energizer”or simply“sinking of middle qi.”it is often a further development of deficiency of spleen qi and may occur in some cases of chronic colitis,functional disorders of the intestines,prelapse

45、of the rectum or uterus,and probably also in gastroptosis and other visceroptosis in west medicine.8.Sinking of spleen qi(2)vClinical manifestations:Deficiency of spleen qi(or yang)plus bearing-down sensation in the abdomen,Incessant diarrhea,Dripping of urine after urinationProlapse of the rectum o
