| 1．ObjectiveThe objective of this research is to discover the geriatrician Zhujiangui's know-how of treating aged patients, and to learn the rules of Traditional-Chinese-Medicine(TCM) for geriatrics, from theory to clinical prescription. This research uses the 8 elements of Syndromes to analysis the database in order to know the main types of TCM diagnosis for geriatrics, and to discover its clinical symptoms and its impact to TCM structure in prescriptions. The elements are four type Syndromes of deficiency, including Qi Deficiency, Blood Deficiency, Yin Deficiency, and Yang Deficiency, and four type Syndromes of excess, namely Maladjusted Qi-Ji, Blood Stagnation, Damp Phlegm, and Fiery Hot. Hopefully, Zhu's database can be well explained by those 8 elements, hence it can find an easy way to conclude experts' experience.2．MethodThis empirical research is based on the technique of data mining, and the method for clinical epidemics is the descriptive studies. The statistics focus on frequency analysis. Meanwhile, chi-squire test is applied to some outcomes.3．ResultThe distribution of Syndromes: The truncated data set of aged 45 and over includes 870 cases. Its multi-Syndrome analysis in 2-dimention shows that Yin Deficiency + Fiery Hot rated as 14%,Damp Phlegm + Fiery Hot rated as 9．4%,Yin Deficiency + Maladjusted Qi-Ji rated as 8．6%,Damp Phlegm + Maladjusted Qi-Ji rated as 6．8%,Qi Deficiency + Damp Phlegm rated as 6．7%,and Yin Deficiency + Damp Phlegm rated as 5．5% are examined with chance over 5%. Such outcome is consistent with the result analyzed by the whole data set 952 cases from the database.Relations between aging and Syndrome: The rate of data with Syndrome of Excess seems decreasing with age, while the relation between aging and the rate of data with Syndrome of Deficiency is not significant.Relations between Syndrome and symptom: The results of analysis of tonque and pulse for each Syndrome are similar and not distinguishable, due to the decomposed data structure. Fortunately, other clinical symptoms make the 8 groups distinguishable from one another, hence those construct 8 series of symptoms for diagnosis.Relations between Syndromes and prescriptions: According to the frequency counted under Syndromes, the top 3 decoctions(/ and medicines )in Zhu's prescription for aged 45 and over are shown as following:(1) Syndrome of Qi Deficiency : buzongyiqitang, shenqiwan, and wupiyin/ Largehead Atractylodes Rhizome, Common Yam Rhizome, and Liquorice Root.(2) Syndrome of Blood Deficiency: suanzaorentang, ganmaidazaotang, and tianwangbuxindan/ Chinese Angelica, Rehmannia Root, and White Peony Root.(3) Syndrome of Yin Deficiency: suanzaorentang, qijudihuangwan, and zhibaidihuangwan/ Rehmannia Root, Common Yam Rhizome, and Asiatic Cornelian Cherry Fruit.(4) Syndrome of Yang Deficiency: shenqiwan, wupiyin, and ganmaidazaotang/ Prepared Commom Monkshood Daughter Root, Asiatic Cornelian Cherry Fruit, and Common Yam Rhizome.(5) Syndrome of Maladjusted Qi-Ji: sinisan, ganmaidazaotang, and zhizichitang/ Liquorice Root, White Peony Root, and Chinese Thorowax Root.(6) Syndrome of Blood Stagnation: huoluoxiaolingdan, duhuojishengtang, and shenqiwan / Chinese Angilica, Danshen Root, and Paniculate Swallowwort Root.(7) Syndrome of Damp Phlegm: wendantang, pingweisan, and sanrentang / Liquorice Root, Coix Seed, and Pinellia Tuber.(8) Syndrome of Fiery Hot: zhibaidihuangwan, ganmaidazaotang, and suanzaorentang / Liquorice Root, Common Anemarrhena, and Indian Bread.4．ConclusionThe research shows 91．4% of 952 cases can be grouped into the 8 elements of Syndrome, and the difference in clinical symptoms and prescriptions exists among Syndromes. That means these 8 elements can well explain the data. Those 8 distinguishable series of clinical symptoms and prescriptions compared to Syndromes, are consistent with TCM theories. Such outcome not only builds a simple model to learn the expert's experience, but also gives a good mark for Zhu's practice in geriatrics. |
