| 3 | The action of medicinal animal horns on Escherichia coli growth investigated by microcalorimetry and chemometric analysis显示文摘The action of Cornu Cervi Pantotrichum (CCP), Cornu Cervi (CC) and Cornu Saigae Tataricae (CST) on Escherichia coli growth were investigated using microcalorimetry to find the heat change regularity of microbial growth. The similarity of thermogenic curves and thermodynamics parameters were investigated as evaluation index, such as the growth rate constant in the first expo- nential phase (k1), maximum power in the first exponential phase (P1), maximum power in the secondary exponential phase (P2), peak time in the first exponential phase (T1), peak time in the stationary phase (T2) and the total heat production in stage 1 (Q1), and the total heat production in stage 2 (Q2). Chemometric analysis was used as a reference for the bioactivity evaluation of medicinal animal horns. The results indicated that the similarity between CST and the control was smaller than that between CCP, CC and the control. Both CCP and CC could increase the heat in the microbial growth, whereas CST decreased it. The biotic thermal activity of different medicinal animal horns was objectively, qualitatively, and quantitatively evaluated by the similarity of thermogenic curves and thermodynamics parameters analysis. | YAN Dan HAN YuMei LUO JiaoYang ZHANG Ping TANG HuiYing PENG Cheng XIAO XiaoHe | 2010 | Chinese Science Bulletin2010,55,26: | 6 |
| 4 | 大黄药材两种化学型对金葡菌生长代谢热动力学变化的影响显示文摘大黄药材可根据酸水解后所含大黄酸和大黄酚在总蒽醌中所占比例高低分为大黄酸型和大黄酚型两种化学型。为了确证大黄药材两种可能的化学型是否具有生物活性或药效学差异, 本文采用微量量热法比较了两种化学型大黄药材对金葡菌的抑制作用。通过调整加样量, 使所有药材作用于金葡菌的总蒽醌量相等, 以凸显大黄药材不同化学型抑菌活性的差异性。结果显示, 金葡菌在大黄酸型药材作用下第一指数生长期速率常数 (k1) 显著低于大黄酚型药材, 提示大黄酸型药材对金葡菌的抑制作用明显强于大黄酚型药材。但大黄酸型药材的抑菌活性与大黄酸含量之间未发现明显相关性, 提示大黄药材对金葡菌的抑制作用除与化学型有关外, 可能还受到其他未知特征成分的影响, 且该成分在大黄药材中的积累规律可能与大黄酸相似。本文采用微量量热法证明了两种化学型大黄药材的抑菌活性存在客观差异, 佐证了大黄药材可根据大黄酸和大黄酚的比例关系区分化学型的合理性, 亦为从化学角度制订大黄药材的商品规格标准提供了参考。 | 张学儒 王伽伯 肖小河 刘塔斯 楚笑辉 周灿平 金城 | 2010 | 药学学报2010,45,9: | 6 |
| 5 | A quality evaluation strategy for Rhizoma coptidis from a variety of different sources using chromatographic fingerprinting combined with biological fingerprinting显示文摘Most of herbal medicines of different sources are used for the same treatment goal in clinic despite their tremendous differences of the quality.Because the clinical efficacy is closely related to the quality of medicines,the implementation of an effective quality control(QC)process is vital.Chemical methods based on content determination and chromatographic fingerprints(CFs)have been recommended as powerful tools.In spite of advances in QC,it is still difficult to determine that which of the chemical compositions can best reflect the correlation with the desired biological activity.Herein,we have focused on the biological activities of multi-source herbal medicines to establish an analytical method.By looking for correlations between the biological activities and their chemical compositions,the method can identify reasonable chemical indicators or chemical methods with biological activity information.In this study,high-performance liquid chromatography(HPLC)and microcalorimetry are combined as a useful method for evaluating the quality of Rhizoma coptidis from different sources.The results of biological fingerprints(BFs)showed that the antibacterial activity sequence of R.coptidis of different sources was Coptis teeta Wall.(CT)>Coptis chinensis Franch.(CC)>Coptis deltoidea C.Y.Cheng et Hsiao(CD).The'spectrum-activity'relationships between CFs and BFs were investigated using the canonical correlation analysis(CCA).Compared with the CCA result of CFs and BFs,the canonical correlation coefficient r1and r2were 0.9974 and 0.9752,respectively.It revealed that there are a close correlation between the spectrum-activity relationships and several of the major anti-bacterial components in the CFs,including jatrorrhizine,coptisine,palmatine,and berberine.Of course,R.coptidis was only a representative of multisource medical plants.The result of the current study will provide an effective reference for evaluating the quality of multisource herbal medicines. | LI JunXian YAN Dan MA LiNa XIONG Yin YAN ChunXia LI BaoCai PENG Cheng XIAO XiaoHe | 2013 | Chinese Science Bulletin2013,58,33: | 5 |
| 6 | The toxic effect of solubilizing excipients on Tetrahymena thermophila BF_5 growth investigated by microcalorimetry显示文摘The toxic effect of different solubilizing excipients on the growth and metabolism of Tetrahymena thermophila BF5(T.t.BF5) at various concentrations was investigated by microcalorimetry.The thermogenic curves of T.t.BF5 growth were determined at 28°C,and were evaluated by dynamic parameters.The results indicated that the values of growth rate constant(k),maximum power(P1,P2),peak time(T1,T2) and total quantity of heat(Q) varied for different excipients.There was a good linear relationship between k and concentrations(r>0.95,P<0.01).5% inhibition concentration(IC5) of poloxamer 188,Tween 80,PEG 600,PEG 400 and Tween 20 was 2.18,1.07,1.35,0.58,and 0.045 mg/mL,respectively.After the principal component analysis(PCA),Q,k and P1 could characterize the effect of these excipients on T.t.BF5 growth.Comprehensive evaluation indicated that compared with the control group,poloxamer 188 had the weakest toxicity and Tween 20 had the strongest toxicity. | ZHANG ShaoFeng YAN Dan TANG HuiYing YANG Ming WANG YueSheng XIAO XiaoHe | 2010 | Chinese Science Bulletin2010,55,18: | 4 |

| 9 | 基于微量量热技术的注射用增溶辅料生物安全性评价显示文摘为筛选适宜的注射用增溶辅料、减少注射剂不良反应的发生,以嗜热四膜虫BF5为模式生物,建立基于微量量热技术的注射用增溶辅料生物安全性评价方法.恒温28℃时,监测不同注射用增溶辅料(泊洛沙姆188、吐温80、吐温20、聚乙二醇600、聚乙二醇400)干预嗜热四膜虫BF5生长代谢的热谱曲线,抽提生物热动力学特征参数进行量化评价.结果表明,在不同浓度的上述增溶辅料干预下,嗜热四膜虫BF5生长速率常数(k)、5%抑制浓度(IC5)、最大输出功率(P1,P2)、达峰时间(T1,T2)和发热量(Q)呈现规律性变化;且k与增溶辅料浓度间的线性关系良好(r>0.9),IC5依次是泊洛沙姆188为2.18mg/mL,聚乙二醇600为1.35mg/mL,吐温80为1.07mg/mL,聚乙二醇400为0.58mg/mL,吐温20为0.045mg/mL.主成分分析表明,参数k,P1和Q能够较好体现热谱曲线整体信息,可用于增溶辅料生物安全性的量化评价.这也得到综合评价结果的印证,即在相同浓度下,泊洛沙姆188对嗜热四膜虫BF5生长代谢毒性较小,而吐温20毒性较大. | 张少锋 鄢丹 唐慧英 杨明 王跃生 肖小河 | 2010 | 科学通报2010,55,35: | 2 |
| 10 | 基于微量量热技术与化学计量学表征的角类动物药质量生物评价研究显示文摘着眼于捕获微生物生长代谢过程中能量变化规律,采用微量量热技术研究名贵角类动物药(鹿茸、鹿角、羚羊角)对大肠杆菌生长代谢的干预作用,以热谱曲线相似性和生物热动力学参数如第一生长速率常数(k1),第一阶段最大发热功率(P1)、达峰时间(T1)、发热量(Q1),第二阶段最大发热功率(P2)、达峰时间(T2)、发热量(Q2)为评价指标,借助化学计量学对生物热动力学特征参数信息进行辨识与抽提.结果表明,羚羊角与空白样品之间的相似性较鹿茸、鹿角低;鹿茸、鹿角可增加微生物生长代谢过程能量(热量),而羚羊角与之相反.由此提示,运用微量量热技术结合化学计量学,以热谱曲线相似性表征生物活性谱(定性),以生物热动力学特征参数表征生物效价值(定量),可实现定性定量评价不同角类动物药的生物活性. | 鄢丹 韩玉梅 骆骄阳 张萍 唐慧英 彭成 肖小河 | 2010 | 科学通报2010,55,33: | 2 |
| 11 | 黄连的活性成分-黄连素及其生物学功能研究显示文摘黄连素是从黄连中提取的一种天然小分子化合物,在我国已有数千年的应用历史。本文综述了黄连活性成分,旨在为临床应用提供建议。根据已有文献发现,黄连具有潜在抗癌症、抗炎症及抗细菌作用。但血浆中黄连素的浓度与剂量呈明显的非线性关系,由于黄连素的吸收差、可利用性低,即使是动物试验中使用最高剂量也达不到细胞试验中使用最低浓度水平。 | 陈玉华 卢松 | 2020 | 中国饲料2020,,10: | 2 |
| 12 | 基于肠道菌群探讨中医药治疗帕金森病的研究进展显示文摘帕金森病(PD)是常见的神经系统退行性疾病,65岁以上人群患病率3.7%,随着全球人口老龄化进程的持续加剧,PD已演变为全球负担。目前已知PD主要病理特征为纹状体多巴胺(DA)缺乏,中脑黑质DA能神经元的退化以及路易小体(Lewy body)的形成;但PD的病因及发病机制尚不明确。肠道菌群被称为人体的“第二基因组”,参与了代谢、消化、炎症及免疫等多项生理功能的调节。近年来肠道菌群在PD中的作用引起了广泛关注,有研究认为PD主要病理标志物α-突触核蛋白可能起源于肠道,肠道菌群的失调影响PD的病程进展。中医药治疗帕金森病的优势逐渐显现,基于肠道菌群理论,综述中医药治疗帕金森病的研究进展,以期有助于帕金森病的临床诊断和治疗。参考文献64篇。 | 蒙健林 梁健芬 张兴博 文铭钧 邓仙勇 | 2022 | 山东中医杂志2022,41,9: | 1 |
