Rules of Meridians and Acupoints Selection in Treatment of Parkinson's Disease Based on Data Mining Techniques.

OBJECTIVE: To help selecting appropriate meridians and acupoints in clinical practice and experimental study for Parkinson's disease (PD), the rules of meridians and acupoints selection of acupuncture and moxibustion were analyzed in domestic and foreign clinical treatment for PD based on data mining techniques. METHODS: Literature about PD treated by acupuncture and moxibustion in China and abroad was searched and selected from China National Knowledge Infrastructure and MEDLINE. Then the data from all eligible articles were extracted to establish the database of acupuncture-moxibustion for PD. The association rules of data mining techniques were used to analyze the rules of meridians and acupoints selection. RESULTS: Totally, 168 eligible articles were included and 184 acupoints were applied. The total frequency of acupoints application was 1,090 times. Those acupoints were mainly distributed in head and neck and extremities. Among all, Taichong (LR 3), Baihui (DU 20), Fengchi (GB 20), Hegu (LI 4) and Chorea-tremor Controlled Zone were the top five acupoints that had been used. Superior-inferior acupoints matching was utilized the most. As to involved meridians, Du Meridian, Dan (Gallbladder) Meridian, Dachang (Large Intestine) Meridian, and Gan (Liver) Meridian were the most popular meridians. CONCLUSIONS: The application of meridians and acupoints for PD treatment lay emphasis on the acupoints on the head, attach importance to extinguishing Gan wind, tonifying qi and blood, and nourishing sinews, and make good use of superior-inferior acupoints matching.

[Characteristics of traditional Chinese medicine syndromes in patients with acute ischemic stroke of yin or yang syndrome: a multicenter trial].

OBJECTIVE: To explore the composition characteristics of traditional Chinese medicine (TCM) syndromes in patients with acute ischemic stroke of yin or yang syndrome by investigating the characteristics of TCM syndromes at different periods after onset. METHODS: One thousand two hundred and forty-six patients with acute ischemic stroke were admitted in twenty hospitals. According to the "diagnostic criteria of syndrome differentiation of stroke", the characteristics of syndromes in the patients were investigated at the periods of 1-3 days, 4-10 days and 11-30 days after they had ischemic stroke. General distribution of six basic syndromes was compared between the patients with yin syndrome and the patients with yang syndrome at the three periods. The six basic syndromes were wind syndrome, pathogenic fire syndrome, phlegm syndrome, blood stasis syndrome, qi deficiency syndrome, and syndrome of yin deficiency and yang hyperactivity. RESULTS: The percentages of wind, pathogenic fire, and phlegm syndromes in the patients were decreased at the period of 11-30 days as compared with the period of 1-3 days (87.1% vs 79.3%, 52.1% vs 38.7% and 67.1% vs 57.4% respectively, P<0.01). However, the percentages of the syndromes of blood stasis, qi deficiency, and yin deficiency and yang hyperactivity were similar at the three periods (P>0.05). There were no differences in the distribution of yin and yang syndromes among the three periods (P>0.05). The percentages of syndromes of wind, pathogenic fire, phlegm, and yin deficiency and yang hyperactivity were higher (P<0.01), and the percentages of syndromes of blood stasis and qi deficiency were lower (P<0.05, P<0.01) in patients with yang syndrome than in patients with yin syndrome. The complex of three syndromes was the most frequent composition pattern in the patients at the three periods. The percentages of complex syndromes of four or five syndromes were higher, and the percentages of single-syndromes and complex syndromes of two syndromes were lower in patients with yang syndrome than in patients with yin syndrome (P<0.05, P<0.01). The most frequent complex syndromes in patients with yin syndrome were complex syndrome of wind, phlegm, blood stasis and qi deficiency, and complex syndrome of wind, phlegm and qi deficiency; while the most frequent complex syndromes in patients with yang syndrome were complex syndrome of wind, pathogenic fire, phlegm and qi deficiency, and complex syndrome of wind, pathogenic fire and phlegm. CONCLUSION: The main discrimination between the yin and yang syndromes is that the yang syndrome is characterized by pathogenic fire. The syndromes of phlegm, qi deficiency, and blood stasis are not associated with the diagnosis of yin or yang syndrome.

[Effect of yirong oral liquid on the reperfusion injury in rats with cerebral infarction undergoing thrombolysis].

OBJECTIVE: To observe the effect of Yirong Oral Liquid (YROL) on reperfusion injury in rats with cerebral infarction undergoing thrombolysis. METHODS: Clinical reperfusion under thrombolysis was simulated by applying thrombolysis on reversible local cerebral ischemic rat model. In the rat model, effect of YROL on parameters concerning anti-oxidation capability, cerebral edema and ultrastructure of brain were observed. RESULTS: YROL could alleviate the cerebral edema after reperfusion, markedly increase the activity of superoxide dismutase in blood plasma, decrease the content of malonyldialdehyde, inhibit the post-reperfusion lipid peroxidation, and significantly reduce the ischemia/reperfusion injury of nerve cells in brain of rat. CONCLUSION: YROL has definite protecting effect on brain.

[Effect of bushen yizhi recipe on neurotransmitter release in A beta segment neurotoxin induced NG108-15 cellular model of Alzheimer disease].

OBJECTIVE: To observe the effect of Bushen Yizhi Recipe (BSYZR) on neurotransmitter release in A beta segment neurotoxin induced NG108-15 cellular model of Alzheimer disease (AD). METHODS: The levels of choline acetyltransferase (ChAT) activity, synapsin and functional synapse formation rate in the cellular model treated with BSYZR containing serum were determined by Western blot analysis, immunoradiometric assay and electrophysiologic technique. RESULTS: BSYZR containing serum treatment could cause increase of ChAT activity and synapsin level in model cells, as compared with those in normal control model cells treated with non-drug containing serum, it also could regulate the release capacity of transmitter and raise the functional synapse formation. CONCLUSION: BSYZR could reduce the reaction of cell to A beta neurotoxin, indicating that it could be antagonistic to the pathological development of AD by means of raising the neurotransmitter release capacity.
