Neuroprotective effects of Ginkgo biloba dropping pills in Parkinson's disease

Parkinson's disease(PD) is the second most common neurodegenerative disease in the world;however,it lacks effective and safe treatments. Ginkgo biloba dropping pill(GBDP), a unique Chinese G. biloba leaf extract preparation, exhibits antioxidant and neuroprotective effects and has a potential as an alternative therapy for PD. Thus, the aims of this study were to evaluate the effects of GBDP in in vitro and in vivo PD models and to compare the chemical constituents and pharmacological activities of GBDP and the G. biloba extract EGb 761. Using liquid chromatography tandem-mass spectrometry, 46 GBDP constituents were identified. Principal component analysis identified differences in the chemical profiles of GBDP and EGb 761. A quantitative analysis of 12 constituents showed that GBDP had higher levels of several flavonoids and terpene trilactones than EGb 761, whereas EGb 761 had higher levels of organic acids.Moreover, we found that GBDP prevented 6-hydroxydopamine-induced dopaminergic neuron loss in zebrafish and improved cognitive impairment and neuronal damage in methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced PD mice. Although similar effects were observed after EGb 761 treatment,the neuroprotective effects were greater after GBDP treatment on several endpoints. In addition, in vitro results suggested that the Akt/GSK3β pathway may be involved in the neuroprotective effects of GBDP.These findings demonstrated that GBDP have potential neuroprotective effects in the treatment of PD.

OBJECTIVE To prepare gingerol dropping pills and to investigate its protective effect on alcoholic liver injury. METHODS The prescription was selected by orthogonal design method and the effect of the option and ratio of ground substance,the temperature of drug. The hardness,circular degree,the tail formation and the dissolution time were studied. Totally 40 KM mice were randomly divided into control group,model group,gingerol dropping pill group(400 mg·kg^(-1)·d^(-1)) and positive control group(bifendate,150 mg·kg^(-1)·d^(-1)) of 10 mice each. The mice from the model and two drug groups were administrated with liqueur[0.15 mL/(10 g·d)]daily by gavage for 3 weeks,Two hours later,drug group mice were treated corresponding gingerol dropping pill and bifendate. Meanwhile,the control group were gavaged same amount of normal saline. Finally,when the model of acute alcoholic liver injury was established on the 22 stday,Biochemical indicators of ocular blood in mice were observed.We also observed the change of liver morphology. RESULTS Under optimum conditions,we can obtain dropping pills having circular shape,touching with hardness and short dissolution time. Compared with the control group,the levels of alanine transaminase(ALT),glutamic-oxaloacetic transaminase(AST) and malondialdehyde(MDA) in model group were obviously increased(P<0.01),While the activity of Superoxide dismutase(SOD) were decreased. In addition,In model group,mice liver disorders,hepatic lobule fusion,accompanying a large number of patchy sample liver cell vacuoles,various sizes of fat vacuoles appeared in cytoplasm and inflammatory cell infiltration were visible around the central vein. On the contrary,compared with the model group,drug groups attenuated or even reversed hepatic pathological changes. Form gingerol dropping pill group,an increase in hepatic SOD activity and serum ALT and AST activities were found and a significant decrease in hepatic MDA content were also observed(P<0.01). CONCLUSION The prescription of gingerol dropping pills was reasonable,and the preparation process was simple. Gingerol dropping pills can protect liver from alcoholic liver injury to some extend,and the mechanism may be related to its antioxidant effect.

A theoretical study of miRNA155-DNA methylation mediated mitokATP regulating mitochondrial autophagy in the improvement of myocardial ischemia-reperfusion injury by Qishen Yiqi Dropping Pills

In the state of acute myocardial ischemia,miRNA expression can regulate related genes and proteins,reduce myocardial cell damage,and thus play a protective role in the myocardium.However,the specific mechanism still needs to be further explored.Recent studies have found that the opening of the mitoKATP channel can regulate mitochondrial autophagy,and the initiation of miRNA-DNA methylation plays a regulatory role in inducing cell autophagy.The applicant research team previously found that Qishen Yiqi Dropping Pills could significantly improve myocardial ischemia by mediating MitokATP channels to regulate mitochondrial autophagy.,and animal experiments have confirmed that miR-155 plays a significant role in the aspect of autophagy regulates,inflammatory reaction and Vascular smooth muscle cell migration.Therefore,the applicant innovatively proposed that Qishen Yiqi Dropping Pills can regulate miRNA155-DNA methylation to mediate the opening of mitoKATP,thereby regulating mitochondrial autophagy and improving myocardial ischemia.In this paper,the association between mitochondrial autophagy and oxidative stress injury after myocardial ischemia was described,and the possible mechanism of Qisen Yiqi dropping pills regulating mitochondrial autophagy by regulating miRNA155-DNA methylation to mediate MitokATP to improve myocardial ischemia reperfusion injury was discussed,so as to provide theoretical ideas for related research.

Hippocampal CA1 pyramidal cells and neurotrophic factors in a rat model of vascular dementia following Xiongma drop pill versus Ginkgo leaf tablets

BACKGROUND： Previous studies have demonstrated the neuroprotective effects of Xiongma drop pill （XMDP） in a mouse model of vascular dementia. Neurotrophic factors play an important role in repair and regeneration of injured neurons. OBJECTIVE： To compare the effects of XMDP and Ginkgo leaf tablets on the appearance and number of hippocampal CA1 pyramidal neurons, as well as neurotrophic factor content in brain tissues, during vascular dementia formation to explore the neuroprotective mechanisms of XMDP. DESIGN, TIME AND SETTING： A randomized, controlled, animal experiment was performed at the Laboratory of Pharmacology, College of Pharmacy, Harbin University of Commerce between April 2007 and December 2008. MATERIALS： XMDP was prepared by the College of Pharmacy, Harbin University of Commerce, with each 40 mg pill containing ferulic acid （≥ 0.149 mg） and gastrodin （≥ 0.171 mg）. Ginkgo leaf tablets were purchased from Taiyuan Qianyuan Pharmacy, China. METHODS： Healthy, adult, male, Wistar rats were randomly assigned to 6 groups： sham-operation, model, XMDP （high-, middle-, and low- dose）, and Ginkgo leaf tablets. The 6 groups were subdivided into two subgroups according to administration days, i.e., 30 and 60 days, with 8 animals in each subgroup. Rats in the model, XMDP, and Ginkgo leaf tablets groups were subjected to permanent bilateral ligation of the common carotid artery to establish a vascular dementia model. At 8 days after model establishment, all groups received intragastric administration once daily of the following： 10 mL/kg normal saline in the sham-operation and model groups; 0.4, 0.2, and 0.1 g/kg XMDP in the high-, middle-, and low-dose XMDP groups, respectively; and 50 mg/kg Ginkgo leaf tablets in the Ginkgo leaf tablets group. MAIN OUTCOME MEASURES： Hematoxylin-eosin staining was used to observe appearance and to quantify the number of hippocampal CA1 pyramidal neurons. Brain-derived neurotrophic factor and nerve growth factor concentrations in brain tissues were detected by enzyme-linked immunosorbent assay. RESULTS： Following model establishment, hippocampal CA1 neurons exhibited pathological changes. Compared with the sham-operation group, the number of pyramidal neurons significantly decreased （P 〈 0.05 or P 〈 0.01）, and neurotrophic factor concentration increased in the model rats （P 〈 0.05 or P 〈 0.01）. XMDP attenuated neuronal injury in a dose-dependent manner： the number of pyramidal neurons and neurotrophic factor concentrations were significantly increased compared with the model group （P〈 0.05 or P〈 0.01）. High- and middle-dose XMDP resulted in equivalent effects to Ginkgo leaf tablets. In addition, neurotrophic factor concentrations in all XMDP groups, after 60 days of administration, were remarkably greater than corresponding concentrations at 30 days （P 〈 0.05 or P 〈 0.01 ）. CONCLUSION： Hippocampal CA1 pyramidal cells exhibited pathological injury following establishment of the vascular dementia model. Middle- and high-dose XMDP increased neurotrophic factor expression in the brain of vascular dementia rats, which suggested neuroprotection equivalent to Ginkgo leaf tablets.

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。

为了提升益生菌的抗逆性,以明胶/果胶/海藻酸钠复合物为壁材,油凝胶为载体,采用同轴滴注法制备具有核壳结构的嗜酸乳杆菌JYLA-191滴丸,并对其形态和菌株在加工、储存、热处理和消化过程中的稳定性进行评价。结果表明,双层滴丸有着明显的核壳结构且菌株均匀分布在内层油凝胶中。经加工双层滴丸活菌数降低了1.02 lg(CFU/g),较单层滴丸活菌数降幅低0.89 lg(CFU/g)。2种滴丸均能通过上消化道并在结肠中释放。单层和双层滴丸经连续消化后活菌数分别达到6.38 lg(CFU/g)和8.43 lg(CFU/g)。与单层滴丸相比,双层滴丸中的嗜酸乳杆菌JYLA-191在胆盐溶液中展现出更好的抗性,细胞活性没有明显的损失(P>0.05)。单层和双层滴丸均提升了嗜酸乳杆菌JYLA-191的耐热性,且双层滴丸经70℃热处理,细胞活性仍能达到5.39 lg(CFU/g)。2种滴丸在4℃和25℃下储存均提升了细胞的稳定性,其中4℃下储存效果更好。较单层滴丸,双层滴丸包埋的嗜酸乳杆菌JYLA-191稳定性更高。结论:双层滴丸有效了提升嗜酸乳杆菌JYLA-191在恶劣环境下的抗逆性。

麝香通心滴丸预处理对大鼠心肌缺血再灌注损伤的保护作用机制

目的:观察麝香通心滴丸预处理对大鼠心肌缺血再灌注(I/R)损伤后心肌细胞和血管的保护作用及潜在机制。方法:将60只雄性SD大鼠随机分为假手术组(Sham组)、I/R组、麝香通心滴丸组(SXTX组)和阳性组,每组15只。SXTX组以18.90 mg/(kg·d)的浓度灌胃;阳性组以尼可地尔1.35 mg/(kg·d)的浓度灌胃;Sham组和I/R组给予等体积去离子水灌胃。各组均灌胃1周后,行冠状动脉前降支结扎-松解手术,除Sham组外其余各组大鼠结扎左冠状动脉前降支30 min后,再灌注120 min,构建心肌I/R模型。通过心肌苏木精-伊红(HE)染色、心肌Masson染色观察大鼠心肌组织及血管改变;电镜观察心肌细胞和血管的超微结构改变;免疫组织化学法观察血管相关蛋白低氧诱导因子-1α(HIF-1α)和血管内皮生长因子(VEGF)表达情况。结果:与Sham组比较,I/R组大鼠心肌细胞坏死和血管损伤明显,心肌组织中HIF-1α表达增加;与I/R组相比,SXTX组心肌细胞和血管病理结构损伤减轻,缺血区心肌组织VEGF含量明显增加。结论:麝香通心滴丸预处理可保护大鼠心肌细胞和血管I/R损伤,可能与上调VEGF蛋白表达、促进缺血区微血管新生有关。
