目的 探讨影响冠心病二级预防中调脂药物应用依从性的相关因素。方法 按其用药依从性好坏将160例应用调脂药物进行二级预防的冠心病患者分为两组,比较两组性别、年龄、文化程度、婚姻状态、家庭支持、经济情况、对调脂药物认知水平、调脂药物不良反应、医疗服务质量、医疗费用是否报销、求医条件等方面的差异。结果 影响冠心病调脂药物应用依从性的因素有:年龄大、对调脂药物认知偏差、存在调脂药物不良反应、医疗服务不到位、经济情况差。结论 冠心病调脂药物在二级预防应用过程中存在一定程度不依从性,影响因素复杂,应实施相应措施提高其依从性。 相似文献

AbstractAs a part of our continuing research for bioactive constituents from Cynanchum limprichtii Schltr., two new C21 steroidal glycosides limproside A (1) and limproside B (2) were isolated from the roots of Cynanchum limprichtii. Their structures were elucidated on the basis of 1D- and 2D-NMR spectroscopic data as well as HR-ESI-MS analysis. The cytotoxicity of two compounds against two selected human cancer cell lines was assayed. 相似文献

Three new C21-steroidal glycosides presenting an unusual 13,14:14,15-disecopregnane-type skeleton, named inamosides A–C (1–3), together with two known C21-steroidal glycosides, were isolated from the MeOH extract of the roots of Cynanchum inamoeum (Maxim.) Loes (Asclepiadaceae). The aglycone of compounds 1, 2, and 3 has a 2β-hydroxyl, which has not yet been reported in the literature. The structure and relative configuration of the aglycone of compounds 1, 2, and 3 were established by X-ray crystallographic analysis. 相似文献

目的 研究耳叶牛皮消(萝藦科)Cynanchum auriculatum Royle ex Wight(asclepiadaceae)块根的化学成分及其抗氧化活性。方法 药材提取物分部萃取后采用硅胶、Sephadex LH-20柱层析等进行分离纯化,通过理化性质和光谱分析鉴定结构。在H2O2刺激条件下,研究化合物对PC12细胞中超氧化物歧化酶(SOD)活性、过氧化氢酶(CAT)活性以及谷胱甘肽过氧化物酶(GSH-Px)活性的影响。结果 从耳叶牛皮消中分离得到了5个苯乙酮类化合物,分别鉴定为cynandione A (I)、cynandione B (II)、cynandione C (III)、cynanchone A (IV)、cynantetrone (V)。H2O2能降低SOD、CAT和GSH-Px三种抗氧化酶活性,而耳叶牛皮消中的苯乙酮类化合物可抑制H2O2引起的氧化损伤。结论 耳叶牛皮消中的苯乙酮类化合物具有抗氧化活性。 相似文献

Two new C21 steroidal glycosides, cynataihosides E (1) and F (2), together with a known one, sublanceoside H2 (3), were isolated from Cynanchum taihangense. The aglycone of cynataihoside F (2) was also a new compound. Their structures were elucidated on the basis of NMR spectroscopic data, HR-ESI-MS analysis, and chemical evidence. Their cytotoxic activities against three human tumor cell lines (HL-60, THP1, and Caco2) were reported. 相似文献

AbstractTwo new 13,14:14,15-disecopregnane-type C21 steroidal glycosides, namely komarosides R (1) and S (2), along with four known compounds (3–6), were obtained from the 95% ethanol extract of the whole herbs of Cynanchum komarovii Al.Iljinski (Asclepiadaceae). The structures of new compounds were elucidated on the basis of 1D, 2D NMR spectroscopic data and acid hydrolysis. Compounds 1 and 2 showed potent inhibitory activities against human leukemia cell line (HL-60) with IC50 values being 6.2 and 17.6 μM, respectively, compared to the positive control 5-fluorouracil (6.4 μM). 相似文献
