The results showed that there is great difference of 5-HMF level in decoctions from differently processed Schisandra and unprocessed Schisandra; decocting time of 60 rain has some effects on 5-HMF level in decoctions and there is certain quantity 5-HMF in processed Schisandra itself and very little 5-HMF in unprocessed Schisandra. Heating time, heating temperature and treating solvents all have effect on 5-HMF level in decoction of Schisandra. 5-HMF in Schisandra was mainly from processing course. Both long heating time and high heating temperature can increase 5-HMF level in Schisandra. The production of 5-HMF in Schisandra may have some relationships with some polar components, which can dissolve in water, ethanol and acetone, especially in ethanol. To control processing temperature, processing time and treatment with some solvent is very important for controlling 5-HMF level in Schisandra.展开更多

We enrolled 220 patients who underwent surgical operation and survived longer than 3 months, with histologically confirmed adenocarcinoma or squamous cell carcinoma from Jan. 2009 to Dec. 2009. Multiple variables, like age, gender, smoking, alcohol, obesity, family history of cancer, diabetes, hypertension, antidiabetic drugs, tumor staging, pathology, treatments, surgical side as well as lipid levels, were selected. We found that tumor staging was associated with 5-year survival rate of stage I–III NSCLC patients by univariate analysis. Furthermore, diabetes mellitus, hypertension and surgical side were associated with the overall survival of NSCLC patients with stage I, stageⅡand stage III, respectively. In conclusion, the status of chronic disease had potential effect on the postoperative 5-year survival rate of lung cancer patients.展开更多
