Multi-drug resistance (MDR) of cancer cells is a major cause of failure in chemotherapy. To the majority of anti-cancer drugs, tumor cells are able to generate a multi-drug resistance; but there is no common views on the mechanism of MDR. This review summarizes the use of drug delivery system based on nanoparticles to overcome MDR in recent years. Three kinds including non-modified, ligand-modified and multifunctional drug delivery systems are described. Especially, the mechanism of reversing MDR based on nanoparticles is covered. Through efficiently offsetting and antagonizing the action of pumping drugs out of the tumor cells, drug delivery system based on nanoparticles can increase the concentration of the drug in tumors, while reduce the side effects on normal cells and overcome multi-drug resistance. The use of drug-loaded nanoparticles, which combines nanotechnology with the strategy of active and passive targeting administration, has shown significant prospect improving cancer therapy.

Objective To research the efficiency of interactive teaching combined with group discussion in prosthodontics course. Methods Totally 40 stomatology students of 2009 grade were divid-ed into 2 groups by stratified random sampling , 6 males and 14 females in each group. Students in con-trol group were taught by traditional teaching method while those in the test group were taught by interac-tive teaching method during prosthodontics course. Knowledge lectures and cases discussion in interactive teaching method were distributed as ratio of 3∶1 in class time , and network interactive teaching was car-ried out after class. Exam was taken after the course, which included single choices(80 questions, 80 points), true or false questions(20 questions, 20 points) and case analysis(5 questions, 50 points). Full marks of the exam was 150 points and exam time was 150min. Then questionnaire survey was carried out, which included the students' interest in learning and cognition of learning difficulty. Exam scores were statistically analyzed by two sample t-test(α=0.05) and the questionnaire survey results were statistically analyzed by Mann-Whitney U test(α=0.05). Results Average scores were(109.22±8.22) in control group and(126.28±8.72) in test group, with statistical differences(F=1.1254, P=0.000). There were statistical differences between control group and test group in studying interest(Z=-2.869, P=0.004) and difficulty(Z=-2.711, P=0.007). Conclusions Initiative, thinking capacity and scores can be enhance by interactive teaching method which is more efficiently than traditional teaching method.

OBJECTIVETo study the expression of the receptor for advanced glycation end products (RAGE) and the inhibitory effect of advanced glycation end products (AGEs) on testosterone production in rat Leydig cells.
METHODSRat Leydig cells were primarily cultured and the expression of RAGE in the Leydig cells was detected by RT-PCR and immunofluorescence staining. The Leydig cells were treated with AGEs at the concentrations of 25, 50, 100 and 200 microg/ml, respectively, and the testosterone content was determined by ELISA.
RESULTSRT-PCR and immunofluorescence staining exhibited the expression of RAGE in the rat Leydig cells. AGEs remarkably suppressed hCG-induced testosterone production in the Leydig cells in a concentration-dependent manner in the 50, 100 and 200 microg/ml groups as compared with the control (P < 0.01).
CONCLUSIONRAGE exists in rat Leydig cells and AGEs can significantly inhibit the secretion of testosterone in primarily cultured rat Leydig cells.

Fever and sweating are the most common clinical symptoms, which are important parts in the inquiry of traditional Chinese medicine (TCM). Just as Zhang Jingyue said, Firstly inquire for cold and heat and secondly in-quire for the sweating. It placed both symptoms as priorities in the collection of disease history. In the clinical prac-tice, febrile diseases refer to acute exogenous diseases infected by warm evil with the main symptom of fever. And fever is almost throughout the entire process of febrile diseases. It is also known as Han-Bing for the visible varia-tion of sweating in its entire disease process. It is important to identify the abnormality of sweating for the determina-tion of the severity febrile diseases and the level of body fluid shortage. Therefore, two main symptoms for the diag-nosis of febrile diseases are particularly prominent and important. The reasons of sweating and fever in febrile dis-eases have been explored so much but the relationship between them is less which is extremely essential to learn more about febrile diseases. So we are expected to explore this topic to make better use of theories of febrile dis-eases.
