The diagnosis and treatment of prostate cancer are being improved due to the popularized screening of prostate specific antigen. Advanced prostate cancer, in spite of its response to androgen deprivation therapy, may finally develop into castration-resistant prostate cancer (CRPC) and shorten the overall survival of the patients. Many efforts have been made by worldwide researchers for new approaches to the management of CRPC, including new hormonal therapy, cytotoxic chemotherapy, immunotherapy, and bone metastasis-targeted therapy. This paper reviews the emerging agents undergoing clinical evaluation and drugs that have received approval for the treatment of CRPC in order to provide doctors and patients with more treatment options for CRPC and improve the overall survival rate and quality of life of the patients.

Human tissue kallikrein-binding protein (Kallistatin, KAL), a secretory protein that participates in the regulation of multiple signaling pathways by binding to the extracellular receptor, however, at present has not been reported about the intracellular activity, and whether it has the similar biological activity with extracellular activity. Here we constructed no signal peptide KAL (NSK) into the adeno-associated virus vector to explore the intracellular activity of KAL. Both the endothelial cell and lung cancer cells could express KAL, but not secreted after rAAV2-NSK transfection. The proliferation and migration of human umbilical vein endothelial cells (HUVECs) were inhibited, but the apoptosis rate was not affected. The proliferation rates, mobility and tubule formation of all the three tested lung cancer cells, such as NCI-H446, NCI-H460 and A549, were inhibited to different extents. This cellular study not only confirmed the intracellular activity, but also suggested it may serve as a kind of "balance factor" in multi-targeted controlling, which may provide a new train of thoughts to explain the regulatory contradiction in PI3K-Akt signaling pathways by KAL.

OBJECTIVETo observe the effect of Fructus Aurantii Immaturus (FAI) on the electro-activity of small intestines in rats, and evaluate the interrelations between the FAI regulating effect and choecystokinin (CCK) and somatostatin (SS).
METHODSMigrating myoelectric complex (MMC) cyclic period, the ratio of the active time to the cyclic period, and the number of the fast wave within the active time per minute were observed between FAI and the normal saline group by external alimentary canal electrodes; the CCK contents in dorsomedial hypothalamic nucleus (DMH), ventromedia hypothalamic nucleus (VMH), lateral hypothalamus area (LHA) and SS in VMH, LHA, paraventricular nucleus (PVN) by using immuno-chemistry technique and micro-image pattern quantitative analysis and scanning system.
RESULTSThe MMC cyclic period shortened, the ratio of the active time to the cyclic period increased and the number of the fast wave within the active time per minute increased in the FAI group, which showed significant difference from the normal saline group; CCK positive neurons were reduced in the areas of DMH, VMH and LHA, SS positive neurons were increased in the areas of VMH, LHA and PVN in the FAI gioup,which showed significant difference compared with the normal saline and the blank control group.
CONCLUSIONFAI can stimulate the electro-reactivity of small intestines. The stimulative effect of FAI might be related to CCK and SS in hypothamus.
