RESUMO
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, P0.05). 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.
RESUMO
BACKGROUND: The decrease of activity level of choline acetyltransferase (ChAT) and reduction of membrane protein of synaptic vesicles are the main biochemical indexes in Alzheimer disease. Traditional Chinese bushen yizhi formula is of the effects of strengthening the kidney, replenishing qi, generating marrow and nourishing the brain, its medicine-containing serum can effectively protect these changes resulting from amyloid protein.OBJECTIVE: To investigate whether the medicine-containing serum of bushen yizhi formula can improve the pathological injury of neurons induced by amyloid protein metabolites in Alzheimer disease, thus to estimate the therapeutic effect of bushen yizhi formula on Alzheimer disease.DESIGN:A randomized and controlled trial. SETTING:Institute of Neuroscience, Second Affiliated Hospital, Guangxi College of Traditional Chinese Medicine, Nanning 530011, Guangxi Zhuang Nationality Autonomous Region, China; Encephalopathic Institute of Guangzhou University of Traditional Chinese Medicine.MATERIALS:The experiment was conducted from September 2003 to March 2004 at the Research and Development Center of New Drugs of Guangxi College of TCM. Totally 60 healthy Wistar rats of clean grade,three months, were at random divided as blank control and bushen yizhi groups, with 30 in each group. The bushen yizhi formula consisted of Fructus Lycii, Fructus Cnidii, Radix Gingeng, Radix Polygoni Multiflori,Cortex Moutan Radicis, Borneolum, etc. The medicine was prepared before use as 0.176 g/Ml liquid(including 1.13 g/Ml rude drugs).METHODS:① Each of the rats in bushen yizhi group was by garage given 1.0-1.5 Ml prepared liquid per day for consecutive 30 days. Within 4hours after the last administration the serum was isolated at 5 000 r/min for 5 minutes, filtered aseptically, the compliment was inactivated at 56 ℃,then the medicine-containing serum was obtained. The rats in blank control group were given saline of the same volume, and the serum was prepared with the same method. ② For NG108-15 cells, the concentration of amyloid protein 25-35 segments in the culture liquid was 5 μ mol/L, or 1-42 segments, 200 nmol/L, was suitable. ③ NG108-15 cells was first in cubated for a day in CO2 incubator with Dulbecco-improved Eagle medium of 0.1 molarity at 37 ℃, then 5 μmol/L amyloid protein 25-35 segment or 200 nmol/L segment 1-42 was added to continuously incubate for a day, after that the cell models of Alzheimer disease was ready. Then 50 g/L medicine-containing serum or Dulbecco-improved Eagle medium of blank control group serum was taken to replace the original culture liquid, and the amyloid protein segments of the above-mentioned concentration was still added for maintaining the cell models of Alzheimer disease, after 5 days'differentiation incubation, the indexes were detected with those in non-amyloid protein as control. ④ Western blotting, radioimmunoassay and electrophysiological examination were used to investigate the ChAT activity,synapsin protein level and rate of functional synapse formation of NG108-15cells in Alzheimer disease after treatment with the medicine-containing serum of bushen yizhi formula.MAIN OUTCOME MEASURES :The effects of the medicine-containing serum of bushen yizhi formula on ChAT activity, synapsin protein level,rate of functional synapse formation of NG108-15 cells and frequency of miniature plate potential in NG108-15 cells.RESULTS:Totally 60 rats involved all entered the final result analysis.① The effect of the medicine-containing serum of bushen yizhi formula on ChAT activity: In the conditions when there was no amyloid protein or the final concentration of amyloid protein 1- 42 was 200 nmol/L, the ChAT activity in bushen yizhi group was obviously higher than that in blank control group [(1651.2±134.5), (1336.1±268.2), ( 586.1±223.4),(1290.7±381.5)μmol/(g·h); P ＜ 0.05] . ② The effect of the medicinecontaining serum of bushen yizhi formula on synapsin protein level: The absorbance values of synapsin Ⅰa and Ⅰb, in the conditions when there was no amyloid protein, amyloid protein 25-35 and 1-42, were respectively 5.02, 1.36 and 2.46 in bushen yizhi group; and 3.18, 0.57 and 0.71 in blank control group. The values in bushen yizhi group were respectively 1.6,2.4 and 3.5times those in blank control group. ③ The effect of the medicine-containing serum of bushen yizhi formula on functional synapse formation of NG108-15 cells: In the conditions when there was no amyloid protein or amyloid protein 1-42, the levels of functional synapse formation in bushen yizhi group wereall higher than those in blank control group [(90.6±6.0)%, (63.2±17.0)%, (58.0±13.1)%, (34.2±13.0)% ;P＜0.05].④ The effect of the medicine-containing serum of bushen yizhi formula on frequency of miniature plate potential in NG108-15 cells: In the conditions when there was no amyloid protein or amyloid protein 1-42, the frequencies of miniature plate potential in bushen yizhi group were all higher than those in blank control group [(9.28±4.1), (5.48 ±5.14), (5.55±5.85),(3.05±4.46)/min; P ＜ 0.01, P＜ 0.05].CONCLUSION:In the conditions when there existed no amyloid protein or amyloid protein, the medicine-containing serum of bushen yizhi formula can raise ChAT activity, not only correct the decrease of cellular synapsin caused by amyloid protein, but also raise the expression of synapsin protein, the rate of functional synapse formation and neurotransmitter release under the condition of no amyloid protein. It was shown that the prescription can antagonize the pathological development of Alzheimer disease, and play the therapeutic effect through enhancing the release power of neurotransmitter.
RESUMO
[Objective] To explore the counteractive mechanism of Tongmai Injection (IT) for excitotoxicity in rats with cerebral ischemia/reperfusion by observing the glutamic acid (Glu) content and N-methyl-D-aspartate (NMDA) receptor activity in rats cortex. [ Methods ] Rat models with cerebral ischemia/reperfusion were established by four-vessel occlusion. Glu content and NMDA receptor activity were examined by radioimmunoassay and the effects of TI on Glu and NMDA receptor were also observed. [ Results ] Glu content and NMDA receptor activity were both increased in the model group and TI could counteract the above changes. [Conclusion] Cerebral ischemia/reperfusion can induce excitotoxicity and TI can protect the cerebral cortex.
RESUMO
Up to now, advantages and disadvantages in the treatment of hypertensive middle_ and large_amount cerebral hemorrhage (HMLCH) by western medicine or traditional Chinese medicine,or by medical treatment or surgical treatment still exist. Mortality and disablement rate remain high. Western medicine combined with Chinese herbal medicine shows better effect in treating HMLCH, but the related research is preliminary. Therefore, thoughts of establishing comprehensive therapeutic protocols for HMLCH are presented as follows. Western medicine combined with Chinese herbal medicine is the fundamental therapeutic principle. Proper surgical operation should be employed promptly to clear away hemotoma and relieve the symptoms first according to the situation of the patient, hospital and the surgeon. Clearing heat and calming the liver, removing blood stasis and phlegm, relaxing the bowels and restoring consciousness are the fundamental therapeutic methods for HMLCH with yang_excess syndrome, and reinforcing Qi and activating blood circulation, removing phlegm and dredging channels, relaxing the bowels and restoring consciousness for yin_excess syndrome. Routine treatment and symptomatic treatment also should be taken into account.
RESUMO
Yiqi Huoxue Oral Liquid(YHOL) was a formula with Qi Reinforcing and bind-circulationactivating actions consisting of Radix Astragali seu Hedysari,Heada,Radix Ilicis Pubesceatis,etc,To study its Pharmacological mechanism, the effects of YHOL on cerebral edema and ultra- struture of cereblal ischemic rat model after reperfusion were observed. The results showed that YHOLdecreased the water content of ischemic barn to some extent, alleviated the neurological symptoms andreduced the damage of brain ultrastructure in the early stage of reperfusion. It is indicated that YHOLcan reduce cereblal edema by protecting the fumction of vascular endothelial cell and the integrity of basicmembranes and improving microcirculation, and exerts a protective effect on the delayed death of neuron.This will Provide an experimental evidence for the clinical application of YHOL.
