Roles and mechanisms of traditional Chinese medicine and its active ingredients in treating epilepsy / 中国中药杂志

At present,Western medicine is widely used in the treatment of epilepsy.However,about 30%-40% of epileptic patients are resistant to them and are affected by the side effects of these drugs.Traditional Chinese medicine is effective in treating epileptic seizures and relieving complications caused by Western medicine.However,the active ingredients and mechanisms of traditional Chinese medicine remain unclear.This article reviews and summarizes the advances and mechanisms in treating epilepsy,such as Chinese medicine monomer,the extracts of single Chinese medicine and Chinese medicine compound.Chinese medicine monomers,including gastrodin,asarone,rhynchophylline,ligustrazine,tanshinone ⅡA,curcumin,etc.,have antiepileptic effects via regulating excitatory neurotransmitters and receptors,the expression of inflammatory factors,sodium/potassium ion channels and the expression of apoptotic protein,therefore protecting neurons.The extracts of single Chinese herbal including the extracts of Gastrodiae Rhizoma,Acori Tatarinowii Rhizoma,Ginseng Radix et Rhizoma,Ganoderma,Scutellariae Radix and Ginkgo Folium,etc.,have antiepileptic effects related to the inhibition of γ-aminobutyric acid receptor,upregulation of phosphatidylinositol 3-kinase signaling pathway and reduction of glutamate-induced excitotoxicity and oxidative stress response.Furthermore,these extracts can regulate ion channels and reduce oxidative damage of neurons.Chinese medicine compounds including Dianxian Qing Granules,Danxing Ningxian Granules,Huoxue Dingxian formulae,etc.,can improve the therapeutic effect on epilepsy through simultaneously regulating excitatory transmitters,apoptosis factors and cytokines.

Effect of Tibetan medicine zuotai on the activity, protein and mRNA expression of CYP1A2 and NAT2 / 药学学报

To study the effect of Tibetan medicine Zuotai on the activity, protein and mRNA expression of CYP1A2 and NAT2, three different doses (1.2, 3.8 and 12 mg x kg(-1)) of Zuotai were administrated orally to rats once a day or once daily for twelve days, separately. Rats were administrated orally caffeine (CF) on the second day after Zuotai administration, and the urine concentration of CF metabolite 5-acetylamino-6-formylamino-3-methyl-uracil (AFMU), 1-methyluric acid (1U), 1-methylxanthine (1X), 1, 7-dimethylxanthine (17U) at 5 h after study drug administration was determined by RP-HPLC. The activity of CYP1A2 and NAT2 was evaluated by the ratio of metabolites (AFMU+1X+1U)/17U and the ratio of AFMU/(AFMU+1X+1U), respectively. The protein and mRNA expression of CYP1A2 and NAT2 were determined by ELISA and RT-PCR method, respectively. After single administration of Zuotai 3.8 mg x kg(-1) and repeated administration of Zuotai 3.8 and 12 mg x kg(-1), the activity of CYP1A2 and NAT2 decreased significantly compared with control group and there was no significant difference between other dose group and control group. The protein expression of CYP1A2 was significant lower than that in control group after repeated administration of Zuotai 12 mg x kg(-1), and the mRNA expression of CYP1A2 decreased significantly compared with that of control group after single administration of Zuotai 3.8 mg x kg(-1) and repeated admistration of Zuotai 12 mg x kg(-1), separately. The protein expression of NAT2 decreased significantly compared with that of control group after single and repeated administration of Zuotai 3.8 mg x kg(-1), respectively, and the mRNA expression of CYP1A2 decreased significantly compared with control group after single administration of Zuotai 3.8 mg x kg(-1). This study found that Tibetan medicine Zuotai had significant effect on the activity, protein and mRNA expression of CYP1A2 and NAT2.

New percutaneous absorption herbal patch for asthma of paracmasis and its effect on the relative transcription factors of patients / 中国针灸

<p><b>OBJECTIVE</b>To observe the therapeutic effect and mechanism of new percutaneous absorption herbal patch for asthma of paracmasis, and to optimize the form of the patch.</p><p><b>METHODS</b>One hundred and twenty cases of paracmasis asthma were randomly divided into medicine patch group, medicinal vesiculation group and western medication group with 40 cases for each. The new percutaneous absorption herbal patch was applied on medicine patch group. Traditional medicinal herbs cake of the hospital were applied on medicinal vesiculation group. Feishu (BL 13), Fengmen (BL 12) and Dazhui (GV 14) were adopted for both groups. Each patch was applied for 6 hours and once every other day. Accuhaler was applied on the western medicine group with 2 inhalations a time and twice a day. Clinical symptom scores, number of attacks and asymtomatic days were observed right before, after and half a year after the treatment. Meanwhile, the expression level of IgE, IL-4, GATA-3 mRNA and T-bet mRNA were observed and compared before and after the treatment.</p><p><b>RESULTS</b>Clinical symptom scores of all the 3 groups were improved (all P < 0.01). The differences of the total effective rate, number of attacks and asymtomatic days of all the 3 groups are without statistical significance (all P > 0.05). However, the long-term therapeutic effect in half a year after the treatment showed that the total effective rate of the medicine patch group was 80.0% (32/40), and the medicinal vesiculation group was 70.0% (28/40). Both of the them were obviously higher than 47.5% (19/40) of the western medicine group (P < 0.01, P < 0.05). And the medicine patch group surpassed the other 2 groups in controlling the number of attacks and increasing the asymtomatic days (P < 0.05, P < 0.01). The level of IgE and IL-4 of all the 3 groups decreased sharply after the treatment (P < 0.05, P < 0.01). And there was no statistic significance in differences among groups (all P > 0.05). The level of GATA-3 mRNA was obviously decreased, while the level of T-bet mRNA was obviouly increased in the medicine patch and medicinal vesiculation groups (P < 0.05, P < 0.01). And the medicine patch group had obvious superiority on increasing the level of T-bet mRNA when compared with the medicinal vesiculation and western medicine groups (P < 0.01, P < 0.05).</p><p><b>CONCLUSION</b>It is concluded that the new percutaneous absorption herbal patch has exact effect on asthma. The treatment may reverse the imbalance condition of Th1/Th2 through regulation on cell factor and its specific transcription factors.</p>
