Acupoints selection rules analysis of ancient acupuncture for urinary incontinence based on data mining technology / 中国针灸

Based on ancient literature of acupuncture in Canon of Chinese Medicine (4th edition), the articles regarding acupuncture for urinary incontinence were retrieved and collected to establish a database. By Weka data mining software, the multi-level association rules analysis method was applied to analyze the acupoints selection characteristics and rules of ancient acupuncture for treatment of urinary incontinence. Totally 356 articles of acupuncture for urinary incontinence were collected, involving 41 acupoints with a total frequency of 364. As a result, (1) the acupoints in the yin-meridian of hand and foot were highly valued, as the frequency of acupoints in yin-meridians was 2.6 times than that in yang-meridians, and the frequency of acupoints selected was the most in the liver meridian of foot-jueyin; (2) the acupoints in bladder meridian of foot-taiyang were also highly valued, and among three yang-meridians of foot, the frequency of acupoints in the bladder meridian of foot-taiyang was 54, accounting for 65.85% (54/82); (3) more acupoints selected were located in the lower limbs and abdomen; (4) specific acupoints in above meridians were mostly selected, presenting 73.2% (30/41) to the ratio of number and 79.4% (289/364) to the frequency, respectively; (5) Zhongji (CV 3), the front-mu point of bladder meridian, was seldom selected in the ancient acupuncture literature, which was different from modern literature reports. The results show that urinary incontinence belongs to external genitalia diseases, which should be treated from yin, indicating more yin-meridians be used and special acupoints be focused on. It is essential to focus inheritance and innovation in TCM clinical treatment, and applying data mining technology to ancient literature of acupuncture could provide classic theory basis for TCM clinical treatment.

Effect of Tween 80 on yuxingcao injection and volatile oils from Houttuynia cordata / 中国中药杂志

<p><b>OBJECTIVE</b>To research the effect of polysorbate 80 (Tween 80) on Yuxingcao injection and volatile oils from Houttuynia cordata.</p><p><b>METHOD</b>1H-NMR spectra of aldehydic and new matter in Yuxingcao injection, volatile oils of H. cordata, and solutions of Tween 80 and volatile oil of H. cordata are determined and compared from various angles of growing origin, storage temperature, and storage time.</p><p><b>RESULT</b>Three aldehydic singlets in 1H-NMR spectra of every volatile oil from 4 aerial part of H. cordata were observed. These aldehydic peaks were basically disappeared and a new peak at delta 8.30 was found in 1H-NMR spectra of the volatile oil solutions in tween 80. Any obvious aldehydic peak in 1H-NMR spectra did not be observed in Yuxincao injection. A weak peak at 8 8.30 was found in 1H-NMR spectra in Yuxincao injection, and the peak high of delta 8.30 was remarked gone up when the injection was stored in 40 degrees C for 1 to 3 months.</p><p><b>CONCLUSION</b>Tween 80 might cause the obvious reduce of aldehydic compounds contents and the production of a novel singal at delta 8.30 in 1H-NMR spectra when it was mixed with the volatile oil from the aerial part of H. cordata. The novel signal at delta 8.30 in 1H-NMR spectra existed in Yuxincao injection and was very small, but was increased remarkably when the Yuxincao injection was stored at 40 degrees C for 1 month at least.</p>
