The result expressed that under the concentration of 0.2mg/mL, the 6 compounds are all active to Sarcina lutea, ME-1, MT-6, MT-land MT-7 are active to Bacillus megaterium, to Escherichia coli, only MT-2 is active. The dimeric natural products are intensively existed in botany, most of them have the obvious biological activities. They have been concentrated on in recent years, and they are one of the compounds to which are enjoyed great popularity in natural product.

结果表明，在浓度为0.2mg/mL的条件下，六种化合物对藤黄八叠球菌均具有明显抑制作用，ME-1、MT-6、MT-1、MT-7对巨大芽孢杆菌有抑制作用，MT-2对大肠杆菌有抑制作用，对绿脓杆菌和枯草芽孢杆菌六种成分均无抑制作用；二聚体化合物在植物界广泛存在，多数二聚体天然产物具有显著的生物活性，引起人们的重视，是天然产物化学界研究的热门化合物之一。

Methods On same oral therapy condition,the patients in control groupwere given commmon thoracocentesis on twice a week,the patients in experimental groupwere treated by thoracic tube intubation with veinal catheter.After drainage within3days,the pleural cavity of the paˉtients in group E were injected with the compound of sodium hyaluranate,sodium carboxymethylcellulose and butyltriˉamcinolone.The patients of two groups were examined by X-ray after6months.According to the database of normal crowd chest X-ray photograph,the area of patient's photograph was drawn.The value of average gray scale in the area was gathered by image analysis system and to be compared with the value of normal side,so the gray ratio was got after correction.

在口服给药条件一致的前提下，对照组患者沿用常规每周2次间断抽液的方法；实验组采用静脉留置针持续引流的方法，3日内将胸液引流尽后注入由透明质酸钠、羧甲基纤维及丁基去炎松组成的可吸收生物活性凝胶。6个月后行胸片检查，图像分析系统根据正常人群胸片同侧拟合区域采集平均灰度值并与健侧相比，经校正后得灰度比。
