Severe acute pancreatitis (SAP) is a common acute abdomen clinical problem characterized by high mortality, multiple complications, complicated pathogenesis and difficult treatment. Recent studies found traditional Chinese medicine (TCM)monomers have markedly good effect for treating SAP. Many TCM monomers can inhibit pancreatin, resist inflammation, improve microcirculation and immunoloregulation, etc. to block the pathological progress of SAP in multiple ways, reduce complications and lower mortality with rapid effects. It is significant for enhancing SAP treatment to deeply understand the current situation in TCM monomers for treating SAP and take precious references therein. This article summarizes the treating effects and mechanisms of TCM monomers for SAP in recent years. 相似文献

Study progress in therapeutic effects of traditional Chinese medicine monomer in severe acute pancreatitis 总被引：8，自引：0，他引：8
INTRODUCTION Severe acute pancreatitis (SAP) is one of the three main acute abdominal problems always ac-companied by multiple-system and multiple-organ impaired function or failure. Its onset and develop-ment are characterized by rapid changes, complicated illness state and difficult treatment. With the con-tinuous development of the traditional Chinese medicine industry in recent years, it is proved that traditional Chinese medicine (TCM) monomers monomers have a marked effect for … 相似文献

1 Introduction 1 During the last decade a new kind of material called geopolymer has emerged as a viable alternative for many conventional cements and plastics. Geopolymer is inorganic polymer derived from metakaolin and sodium silicate solution. It can be synthesized at low temperature and have useful properties such as high compressive strength. It is stable at temperatures up to 800 °C and even 1150 °C while ordinary Portland cement loses its strength at 500 °C [1]. Several microstruct… 相似文献

不同药物对大鼠心肌缺血模型作用效果的比较 总被引：2，自引：0，他引：2
利用硝酸甘油、二硝酸异山梨醇、人参二醇组总皂甙有人参皂甙单体Rb1观察它们对大鼠心肌缺血模型的影响。结果表明：人参二醇组总皂甙及人参皂甙单体Rb1在一定剂量条件下对心肌缺血的恢复作用要明显高于硝酸甘油及二硝酸异山梨醇（异舒吉），反映在疗效显著、时间短，从而能够有效地抑制大鼠心肌缺血。 相似文献
