Fromthe point of view of chemical components,α-cellulose content for differentage-degrees bamboo is mostly the same,slightly increasing with the growth ofage,lignin content increases with the growth of age,the contents of extract,hemicellulose,polysaccharose,mineral elememts decrease with the growth ofage;the result shows the electric conductivity of bamboo is mainly decided bythe content of mineral elements,with the growth of age,volume resistivitybecomes great.pH value shows acid,acidity decreases with the growth of age,this is mainly due to the decrease of fraction of bamboo parenchyma with thegrowth of age.

从化学成分角度来说，不同年龄竹材α-纤维素含量差异不大，一般随着年龄增大而增大；木质素含量随着年龄增大而增大；抽提物、半纤维素、聚戊糖、灰分含量随着年龄增大而降低；研究表明竹材的导电性主要由矿质元素含量大小决定，随着年龄增大，体积电阻率越来越大；pH值呈酸性，酸性随着年龄增大而减弱，这主要由于竹材薄壁组织比量随着年龄增加而减少，内含物如淀粉减少，导致酸性减弱。

objective trimetazidine has shown anti-ischemic properties to improve exercise tolerance without haemodynamic effects and direct cyto protective effect on the myocardium.however,it is not clear whether trimetazidine has beneficially effect on severe ischemic cardiomyopathy.methods 19patients（68±9）years with postnecrotic left ventricular dysfunction（ejection fraction31.7%±5.4%）were studied to examine the benefit of adding60mg a day of trimetazidine for3months to the classical therapy.the assessment included clinical evaluation,electrocardiography and echocardiography.results after adding60mg a day of trimetazidine for3months,attack of angina was relieved and dyspnea was improved（p.05）.but heart rate,systolic blood pressure,rate pressure product,ejection fraction,left ventricular volume and global wall motion index were not changed.conclusion trimetazidine seems to improve clinical status while can not change oxygen supply-to-demand ratio without adverse effects in patients on severe ischemic carˉdiomyopathy.

目的 曲美他嗪是一种新型的抗心肌缺血的药物，能够改善患者的运动耐量和心肌的直接保护作用同时并没有血流动力学效应。但目前对于严重缺血性心肌病患者的临床治疗价值还需要进一步观察。方法 19例（68±9）岁确诊为缺血性心肌病（左心室射血分数0%）的患者在常规治疗的基础上加用每日60mg曲美他嗪治疗3个月，随诊观察患者临床情况以及超声心动图指标的变化。结果 19例患者均可耐受在常规治疗基础上加用每日60mg曲美他嗪的治疗，随诊发现患者心绞痛发作明显减少，运动耐量明显改善。同时患者心率、收缩压、心率血压乘积、左心室射血分数、左心室容量以及整体室壁运动指数无明显改变。结论缺血性心肌病的患者在常规治疗基础上加用曲美他嗪是安全的，同时其能明显改善患者的临床状态，而这种作用并不改变心肌氧的供求比值。
