As to the diagnosis and treatment of tinnitus,syndrome differentiation is not out of six-meridian syndrome differentiation.Clinically,the doctor should follow the principle of differentiating the six meridians the first and differentiating the formula and syndrome the second,identify in detail the assignment of six meridians,differentiate the cold and heat,interior and exterior,deficiency and excess.Only in this way can the doctor not make a mistake of principle.Tinnitus is manifested as pathogenic qi disturbing the orifices,which mainly belongs to Shaoyang semi-exterior and semi-interior heat syndrome,but the symptoms of Taiyin water stagnation attacking upward are not uncommon.For the tinnitus caused by Shaoyang heat of semi-exterior and semi-interior syndrome,Shaoyang reconciliation method may obtain an effect;for the tinnitus caused by Taiyin interior,deficiency,cold,and the upward attack of water retention,the method of warming the stomach,dropping the adverse and soothing the water retention may be effective.

Classical formulas attach great importance to syndrome differentiation of deficiency and excess,emphasize the selection of an appropriate treatment regimen according to the level of struggle between the healthy qi and pathogens,either eliminating pathogens to reinforce the healthy qi,or reinforcing the healthy qi to eliminate pathogens.On the basis of syndrome differentiation of six meridians,the paper emphasizes the reinforcement of the healthy qi and the treatment with both elimination and reinforcement to eliminate pathogens but not to hurt the healthy qi.It is concluded that yang qi,blood and body fluids should be paid attention to in the clinical process,and blind attack to the pathogens be prohibited.

<黄帝内经>、<伤寒杂病论>被称作中医学经典,分别成书于秦汉时期和东汉末年,虽然2部著作成书年代相去不远,但理论指导思想却大相径庭.历代认为<伤寒论>理论来源于<黄帝内经>,其依据就是<伤寒论>序中有"撰用素问、九卷、八十一难、阴阳大论、胎胪药录并平脉辨证"23个字.因此,历代医家多以<内经>解读伤寒,致使仲景学术本源累世迷惑莫辨.

八纲是中医重要理论,八纲辨证是临床最基础和适用范围最广的辨证方法。但近来医家多认为八纲确立于近代,八纲一名虽然始自近代祝味菊先生,但历代已对八纲进行了论述,并已明确指出八纲的临床重要性和实用性。从中医理论源泉的《黄帝内经》中可见大量的对八纲实质内容的论述,八纲实际上起源于《黄帝内经》。

There were unique characteristics of the theoretical system of classic formula,which was originated from Shennong Bencao Jing and Tangye Jing,with Shanghan Zabing Lun as the representative masterpiece.The syndrome differentiation and treatment methodology was a unique way to recognize the usual laws of the human body,and a universal method to reorgnize the body condition into the functional whole.The executive provedure of classic formula was to identify the Six Jing,and then the precise formula-syndrome,usually deduced from the main symptoms of the Six Jing.The theory of classic formula was an practical evolution of the Eight Principles Theory.The Six Jing Theory was a unified philosophy of all the diseases,and the differentiation of the formula-syndrome was the essence of the syndrome-differentiation theory.

The article discusses the changes of dosage measurement of herbal Ingredients in terms of the historical evolution of the system of length,capacity and weight,and makes a comparison between the ancient and present use.Textual research and analysis about measurement have been carried out.In the classic formulas one chi was about 23.1 cm,one sheng,200 ml,and one liang 13.8 g,which is more convincing.In the Eastern Han dynasty,there was another system of length,capacity and weight,according to which one liang was about 15.6 g.Some scholars deny existence of the Shen Nong Scale and its influence on the system of measurement.About other systems of measurement in ancient times it needs further investigation.It is suggested that dosage measurement of herbal ingredients in classic formulas and its application deserve a profound study.
