| 1 | DK Crush技术治疗真性冠状动脉分叉病变:与经典Crush技术的对比显示文摘目的检验作者改良的DK Crush技术能否确保最终对吻扩张的成功。方法本研究属于连续、非随机和开放式研究,共入选了88例真性分叉病变(分支血管直径>2.0mm)的患者。其中2004年10月至2005年1月间入选的44例患者接受经典Crush技术治疗,2005年1月至2005年6月间入选的44例患者接受DK Crush技术治疗。比较两组患者术前、术中和术后30d内的诸项参数。结果DK Crush组与经典Crush组比较,患者分支血管病变长度长(13.5±3.4mm比7.8±3.1mm,P<0.05)、经皮冠状动脉介入术需时短(44±12min比68±17min,P<0.05)、最终对吻扩张成功率高(100%比70%,P<0.01)、使用球囊数量少(1.6±0.4个比2.7±0.7个,P<0.05)及造影剂使用量小(102±38mL比176±46mL,P<0.05)。DKCrush组与经典Crush组患者的主干与分支血管之间的夹角[(57±18)°比(47±15)°],主干血管病变长度(24.3±8.6mm比21.1±7.3mm)差异均无统计学意义(P均>0.05)。经典Crush组有两例(4.3%)最终对吻失败的患者出现亚急性血栓栓塞。DK Crush组术后即刻分支血管开口部位最小血管直径显著大于经典Crush组(3.01±0.13mm比2.74±0.12mm,P<0.01),而残余狭窄却显著小于后者(7.3%±8.6%比17.4%±11.2%,P<0.05)。经典Crush组有5例患者术后即刻分支血管开口残余狭窄>30%(对吻失败)。结论经典Crush技术存在的技术缺陷是导致预后不良的主要原因。改良的DK Crush技术能显著提高对吻扩张的成功率,进一步的随机研究可以明确后者的有效性。 | 陈绍良 方唯一 魏盟 何奔 张瑞岩 陈韵岱 张俊杰 叶飞 朱中生 林松 单守杰 杨松 钱均 Damras Michael Lee Tan Huaycheem Tejas Patel | 2007 | 中国介入心脏病学杂志2007，15，2： | 7 |

| 4 | Psychoactive Chemical Constituents of Carissa edulis (Forssk.) Vahl Roots and Its Safety Limits in Folk Treatment: Benzodiazepines Analogous显示文摘Carissa edulis Vahl is well known in Sudanese herbal medicine,commonly used for treatment of epilepsy,headache,chest pains,rheumatism,skin lesions,mania and other psychoactive diseases.The investigations of the safety use for psychoactive purposes in Sudanese healing traditions and identifying secondary metabolites of the plant extracts are the key steps towards determination of appropriate medicinal doses.Therefore,one of the chemical constituents was isolated and structurally identified by 1H-NMR and LC-MS.With the aim of evaluating Carissa edulis folk random uses,the isolated compound was compared with reference artificial drugs Lormetazepam,a potentially toxic compound.Structure investigations confirm that the isolated product was benzodiazepines analogous 7-chloro 1,4-benzodiazepine-2-ones.It is important to know the potential toxicity of certain plant in order to assess the therapeutic effect of it,as these are slight distinctions between the medicinal and toxic doses.In general the results obtained justify the use of the roots of Carissa edulis in traditional medicine for the treatment of some psychiatric diseases. | Intisar Salih Ahmed Damra Elhaj Mustafa | 2020 | Journal of Chemistry and Chemical Engineering2020，14，4： | 0 |
