Methods： Self-developed demographic questionnaire, numeric rating scale and SF-36 questionnaire were used together among 643 cancer pain patients in 28 Grade 2nd to 3rd general hospitals and 2 Grade 3rd cancer hospitals. Results： The SF-36 eight dimensions scores ranged from 31.75 to 57.22 in these cancer pain patients. The t test and Wilcoxon rank sum test were used to compare the QOL between pain controlled （PC） group and pain uncontrolled （PUC） group, and the results showed that patients in PC group had the higher O, OL scores in 6 areas of SF-36 （P〈0.05）. Binary logistic regression results found that pain management satisfaction scores （P〈0.001）, family average personal monthly income （P=0.029）, current receiving chemotherapy （P=0.009） and cancer stage （P〈0.001） were the predictors to cancer pain controlled results. Conclusion： Cancer patients with pain in Beijing had poor QOL. Pain control will improve the QOL of cancer pain patients.展开更多

The effects of green tea are mainly attributed to its polyphenol content, although caffeine, accounting for 2%-4%, appears to be related to the adaptation of mental energy by increasing alertness, attention and cognitive function, as well as elevating mood. L-Theanine, a unique amino acid in tea, has neuroprotective and mood effects. In addition, some studies on functional neuroanatomy and cerebral control of sexual function have demonstrated that the thalamus and hypothalamus play a role in emotional changes, memory and sexual behavior patterns. Our recent epidemiologyresearch has unexpectedly found that tea drinking was positively related with sexual orgasm and sexual satisfaction in female hypertensive patients. We therefore hypothesize that long-term regular consumption of tea may play a role in sexual activity.展开更多
