Xuefuzhuyu decoction and astragalus prevent hypoxic-ischemic brain injury

Hypoxic-ischemic brain injury models were generated by bilateral carotid artery ligation in Sprague-Dawley rats. Successful models were treated with a combination of Xuefuzhuyu decoction and 10g of astragalus. The experimental results showed that neuronal morphology and structure recovered, nerve growth factor mRNA expression increased in brain tissues, and neurological function signifi-cantly improved. There was no significant difference in these measures compared with rats treated with Xuefuzhuyu decoction alone or a combined treatment of Xuefuzhuyu decoction with 40 g as-tragalus. These experimental findings revealed that, Xuefuzhuyu decoction combined with astra-galus may up-regulate the expression of nerve growth factor mRNA and accordingly exert a neu-roprotective effect; however, this protection is not dependent on astragalus dosage.

Effects of Buyang Huanwu decoction and Astragalus mongholicus on platelet activating factor receptor activity in rabbits in vitro

BACKGROUND: The pharmacological action of traditional Chinese medicine compound is the comprehensive effect of the various ingredients, and the interactions of various ingredients are closely correlated with the final effect. In order to reveal the compatibility mechanism of BHD's prescription in treating and preventing ischemic cerebrovascular disease, we needed explore the effect and relation of ingredients in the prescription. OBJECTIVE: To observe the effect of Buyang Huanwu decoction (BHD) and Astragalus mongholicus on the activity of platelet activating factor receptor (PAFR) in the platelet of rabbits in vitro, and investigate the mechanism of Astragalus mongholicus. DESIGN: A decomposed recipes study. SETTING: Guangzhou University of Traditional Chinese Medicine. MATERIALS: Five New Zealand rabbits, weighing 2-3 kg, both sexes, were used. BHD was composed of Sheng Huang Qi 120 g, Dang Gui Wei 6 g, Chi Shao 4.5 g, Chuan Xiong 3 g, Di Long 3 g, Tao Ren 3 g, Hong Hua 3 g. The prescription for activating blood circulation consisted of Dang Gui Wei 6 g, Chi Shao 4.5 g, Chuan Xiong 3 g, Di Long 3 g, Tao Ren 3 g and Hong Hua 3 g. The prescription for invigorating qi consisted of 120 g Sheng Huang Qi. The prepared herbal pieces were purchased from the traditional Chinese medicine Dispensary of Foshan Second People's Hospital, and appraised by Professor Xu from Science of Chinese Materia Medica College, Guangzhou University of Traditional Chinese Medicine. 3H-PAF was supplied by Amersham Co., Ltd. (specific activity: 6. 475 TBq/mmol; batch number: 200402); PAF standard by Biomol Co., Ltd. (batch number: P1318V). METHODS: The experiments were carried out in the Laboratory of Nuclear Medicine, Guangzhou University of Traditional Chinese Medicine from September to December 2004. ① Injections of BHD, prescriptions for activating blood circulation and invigorating qi were prepared by the decoction and alcohol sedimentation technique. Rabbit common carotid artery blood (40 mL) was drawn via intubation to prepare platelet suspension of (0.8-1.0)×1010 L-1. ② Determination of 3H-PAF and washed PAFR binding: The general combination tube (T) contained washed platelet-rich plasma (WPRP) 380 μL + 3H-PAF (0.35 nmol/L)10 μL+distilled water 5 μL; The nonspecific binding tube (P) contained WPRP 380 μL+3H-PAF(0.35 nmol/L)10 μL+cold PAF (1 μmol/L) 5 μL; The sample tube (Y) contained WPRP 380 μL+3H-PAF(0.35 nmol/L)10 μL+experimental medicine (injection of BHD, prescriptions for activating blood circulation or invigorating qi) 5 μL. The test was conducted for three times for each sample in the same way as mentioned above. The samples were shaken on the oscillator for 30 s, then bathed at 25 ℃ for 40 minutes, and the reaction was terminated with cold Tris buffer containing 0.1% BSA, multichannel cell detachment separator was used for vacuum suction to filter the separated free 3H-PAF, and the filter paper was washed with cold Tris buffer for four times, then dried in the baking oven (80 ℃) for 1 hour, and placed in xylol liquid scintillator, and the radioactivity was determined automatically by the liquid scintillation detector. The mean of the three parallel tubes was calculated. The specific binging inhibition rate was calculated: SBIR=[(T-Y)/(T-P)]×100%]. ③ Univariate analysis of variance was conducted. And for comparison of each paired groups, the q test was adopted. MAIN OUTCOME MEASURES: Effect of BHD whole prescription, prescriptions for activating blood circulation and invigorating qi on the specific binding inhibition rate of 3H-PAF and PAFR. RESULTS: BHD, prescriptions for activating blood circulation and invigorating qi were all able to inhibit the specific binding of 3H-PAF to PAFR, the specific blinding inhibition rates were (45.90±7.50)%, (97.90±1.84)% and (26.75±2.48)%, respectively, and there were significant differences between every two groups (P < 0.01). CONCLUSION: Single Astragalus mongholicus (120 g) can inhibit the specific blinding of PAFR in the platelet of the rabbit with 3H-PAF, but the combination of Astragalus mongholicus with the drugs for activating blood circulation in BHD can significantly decrease the inhibiting action of the latter on PAFR activity of the platelet, reflecting the combined mechanism of 'removing blood stasis without injuring the vital qi' in BHD.

Analysis of metallic elements dissolution in the Astragalus at different decocting time by using LIBS technique

Astragalus is an important traditional Chinese herb that has therapeutic potential in the treatment of diseases. In this study, the dissolution of metallic elements during the material decoction process was investigated using laser-induced breakdown spectroscopy(LIBS). The Ca, Mg, Al, and Fe in the drug residues, liquid, and vapor were selected for the study of the transfer of elements after different decocting times. It was found that the intensities of the spectral lines for these elements in the drug liquid increased with increasing decocting times.The contrast trend was observed in the residues and only calcium was detected in the vapor.Furthermore, the relative mass concentrations of Ca, Mg, Al, and Fe in the liquid were quantitatively determined by a combination of the standard addition method and calibrationfree-LIBS method by adding the standard concentration solution of Cu and Cd elements into the drug liquids, it can be found that the maximum error between Cd concentration calculated by internal CF-LIBS and the standard is within 10%. This provides a new method of achieving the on-line monitoring and analysis of metallic elements in the production of traditional Chinese medicines.

中药复方基于Wnt/β-catenin信号通路调控糖尿病肾病研究进展

糖尿病肾病是糖尿病最常见的微血管并发症之一,也是造成终末期肾病的主要原因。Wnt/β-catenin信号通路与糖尿病肾病肾小管间质纤维化密切相关,主要通过足细胞、肾小球系膜细胞、肾小管上皮细胞等来改善糖尿病肾病。中药复方基于调控Wnt/β-catenin信号通路来改善肾脏病变及纤维化,保护肾脏功能,进而延缓病程进展,在治疗中发挥激活自噬、减少炎症反应及减弱氧化应激等作用。目前,关于中药复方基于Wnt/β-catenin信号通路的研究仍存在以下不足之处:(1)在中药复方的研究中,能够得出中药复方可通过Wnt/β-catenin信号通路发挥作用,但由于中药复方成份复杂多样,大多数仅仅发现相关性,而没有分析其具体的活性成分;(2)Wnt/β-catenin信号通路的相关研究并未深入探索该信号通路在肾纤维化中的作用机制;(3)目前关于中医药的大部分实验为动物体内实验,缺乏体外细胞的相关实验探究。今后,需加强对中药复方活性成分的研究,并开展更多的体外细胞实验,进行深层次的作用机制及靶点研究。

糖尿病是临床上常见的代谢性疾病,是世界三大慢病之一,患病人口基数巨大。而2型糖尿病的典型表现为“三多一少”,即多饮、多食、多尿或消瘦等,与我国传统医学的“消渴病症”极为接近。因此本文旨在探究我国传统医学经典名方“白虎加人参汤”在2型糖尿病中的运用与研究进展。临床及基础实验研究表明白虎加人参汤具有良好地降糖效果,并具有缓解氧化应激反应、抗氧化能力以及降低血清炎症因子水平的作用,能良好的改善糖尿病患者的临床症状,能在一定程度上替代部分西药降糖,与西药联用起到提高临床疗效作用。

从汗出发热探讨白虎汤、白虎加人参汤、竹叶石膏汤及四逆加人参汤方证

白虎汤证、白虎加人参汤证、竹叶石膏汤证、四逆加人参汤证均有汗出发热的表现,四种方证的病机根本区别为有无里热、津液与阳气的盛衰。白虎汤证的病机为里热亢盛、津气略损,机体多无休克表现;白虎加人参汤证的病机为热盛津亏、津亏为重,机体多有低血容量休克前兆的表现;竹叶石膏汤证的病机为余热未清、气津两伤,机体多处于疾病将愈的状态;四逆加人参汤证的病机为气随血脱、阴阳两虚,机体多已经进入休克状态。四个方剂的用药区别为清热、补益与回阳的侧重比例不同。白虎汤全方以寒凉药物为主导,共奏清解里热之功;白虎加人参汤清热与补益兼顾;竹叶石膏汤则以补气益津为主,清解里热为辅;四逆加人参汤以回阳固脱为主,补气益津为辅。四个方剂在临床运用时,既要审视病机的不同,也要注重病情的动态变化。
