Diabetic Retinopathy Qi Stagnation

This research investigated the pathogenic factors and TCM(traditional Chinese medicine) syndrome's transformation of DR (type2 diabetic retinopathy) by adopting retrospecting method. By discussing pathogenic mechanism and the characteristics of clinical syndrome in TCM of this disease.In order to detect the influence of intenal heat harming yin toward the liver qi-stagnation this clinical study mainly focus on liver-qi stagnation syndrome .The thesis including two parts covering literature review and clinical study.The onset of DR has no relation with the age and gender but is relatcd to the course of disease and the level of blood sugar. The longer the course and the worse the control of blood sugar, the higher the incidence of DR.DM nephropathy, DM retinopathy and DM neuropathy often emerge at the same time or one after the other and usually parallel in severity due to common pathogenesis.Qi-deficiency and Yin-deficiency is the most common syndrome type of DR, and the two are usually seen together. Simultaneous occurrence of detociency and excess syndromes is the TCM pathogenesis of DR, in which of yin-deficiency ,deficiency of both qi and yin, deficiency of both yin and yang while excess syndromes include blood stasis, phlegm-dampness, dampness-heat. The frequency of symptoms is depression) string-like pulse) blood stasis on eyes) deep breath) the taste of bitterness) throat abnormality) chest and brest uncomfortabiltyWith the development of retimopathy ,the syndrome types are changing, in which the deficiency of qi and yin are abating but yang deficiency, blood stasis, phlegm-dampness are aggravating. The most common accompanied syndrome for diabetes is concentrated in eyes which are also the organs that liver-channel pass by, The symdrome of qi-stagnation is highly related with yin-deficiency, blood deficiency, qi deficiency, blood-stasis and damp-heat, blood stasis on eyes is an index for liver-qi stagnation. ConclusionsThrough the study above. We may find that diabetes syndrome of liver-qi stagmation is different with the common syndrome of liver-qi stagnation which shows that the live-qi stagnation syndromes is affected by the basic pathogenesis of diabetes that is internal heat demaging yin and strong fire damaging qi. Syndrome is not only essential reflection for the certain phase of a disease but also a main change in this phase of the disease ,but it is determined by the specicl essence of the disease. Thus, we should base on the basic pathogenesis to identify different pattern in treating diseases which is the key to be effective. Yin-deficiency is the pathological basis of DR, which is acomplication of DM ,marked by a long course and complex pathogenesis. While qi and yin deficiency is the most important pathogenesis(deficiency of both yin and yang can be developed), blood stasis and phlegm-dampness(phlegm-dampness accompanied by heat are more common)are direct causing factors.Superficially-excess and originally-deficiency, or simultaneous occurrence of both ,are the typical syndrone of DR .Active prevention should be taken for those who haven't developed DR yet ,mainly by means of replenishing qi and yin .Treatment methods such as promoting circulation of blood and removing phlegm should be used to prevent it's aggravation for those who have had DR.
