Anticipatory nausea and vomiting (ANV) is one of the common adverse effects in cancer patients undergoing chemotherapy.ANV is related to classical conditioning,psychosocial and demographic factors.Psychological intervention such as systematic desensitization,hypnosis and biofeedback therapy could be used to treat ANV,while some psychotropic medication including benzodiazepines and olanzapine is also helpful to prevent ANV.Now the recognition about ANV in clinical oncology is not adequate and large sample epidemiological survey of ANV is lacked.So far there are no special tools to predict and assess ANV,and the effects of pharmacological interventions also need solid evidence from large sample double-blind randomized controlled trials.

Thiols, which are components of many proteins and simple molecules, play an important role in the cellular antioxidant defense system. The quantitative determination of thiols is important in biochemistry and clinical chemistry. Fluorescent probes, which have its apparent advantages in sensitivity and, most importantly, in imaging thiols in vivo, even in single living cells, appear to be particularly attractive. In this review, we classify the fluorescent probes based on their different reaction mechanisms with thiols and summarize the recent progresses of thiols fluorescent probes with fifty-one

BACKGROUND:The differentiation of neural stem cells (NSCs) is a hot research. Whether brain-derived neurotrophic factors (BDNF) can induce the differentiation of NSCs into neurons has not been detailed studied. OBJECTIVE:To investigate the effect of different concentrations of BDNF on the differentiation of NSCs from adult rat hippocampus into neurons in the medium with epidermal growth factor. DESIGN:A controlled study. SETTING:Department of Human Anatomy, China Medical University. MATERIALS:The experiment was performed at the Neurotomia Laboratory of China Medical University in August 2007. NSCs isolated from hippocampus of adult SD rats were inoculated in a serum-free medium. Three clean adult SD rats (200-250 g each) were provided by Laboratory Animal Department of China Medical University. Dispositions to the rats were consistent with ethical standards of animals. Epidermal growth factor (EGF) and BDNF were bought from R&D Company. METHODS:①NSCs obtained from rat hippocampus were cultured in the serum-free medium containing basic fibroblast growth factor (bFGF), EGF and B27. ②Single cell clone was obtained via limited dilution for the fourth passage of cells. Identification of NSCs for the passage of cells from monoclonal spheres was performed by Nestin immunocytochemistry. Neurons and astroglial cells were identified by immunocytochemistry for neuron specific enolase (NSE) and glial fibrillary acidic protein (GFAP) a week after differentiation. ③Differentiation for the monoclonal spheres was done to appraisal the proportion of neurons. NSCs were divided for several groups containing 0 μg/L, 50 μg/L, 100 μg/L, 150 μg/L, and 200 μg/L groups according to the doses of BDNF. EGF was added in the media of each group. Immunocytochemistry for NSE was done a week later to count the positive cells. MAIN OUTCOME MEASURES:Proportion of neurons differentiated from NSCs.RESULTS:①NSCs immunocytochemical staining showed that Nestin was positive in monoclonal spheres, and NSE and GFAP were positive in differentiated cells. ②The proportion of differentiation from NSCs into neurons was significantly higher in groups treated with 50 μg/L and 100 μg/L BDNF compared to other groups（t=2.502-5.025, P < 0.05）, but there was no significant difference between 50 μg/L and 100 μg/L BDNF groups（P > 0.05）. Moreover, no significant difference was detected among 0 μg/L, 150 μg/L and 200 μg/L BDNF groups (P > 0.05). CONCLUSION:The optimal concentration of BDNF is 50 μg/L for differentiation from NSCs into neurons while the concentration of EGF is 20 μg/L.
