The present study was to investigate the role of dopamine D1 receptors and its relationship with glutamate, N-methyl-D-aspartic acid (NMDA) receptor and α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptor in depression induced by chronic unpredictable mild stress (CUMS). CUMS-induced depression model was established in Sprague-Dawley rats, and intrahippocampal microinjections of D1 dopamine receptor agonist SKF38393, non-competitive NMDA receptor antagonist MK-801 and AMPA receptor antagonist NBQX were respectively adopted by rat brain stereotaxic coordinates. The behavioral observations were conducted by measurement of weight changes, sucrose preference test, open-field test and tail suspension test. The concentration of glutamic acid and the expression of its receptors' subunits were detected by HPLC and Western blot, respectively. The results showed that, compared with control group, CUMS rats showed depression-like behavioral changes, higher concentration of glutamic acid, lower expressions of NMDA receptor (NR1) and AMPA receptor (GluR2/3) in hippocampus. Pretreatment with injection of SKF38393 could rescue such depression effect of CUMS, decrease the concentration of glutamic acid, and increase the expressions of NMDA receptor (NR1), AMPA receptor (GluR2/3) in hippocampus. Pretreatment with MK-801 could enhance the antidepressant effect of SKF38393, while NBQX weakened. These results suggest that agonists of D1 dopamine receptor could reduce the concentration of glutamic acid in hippocampus, and its antidepressant effect may be mediated by AMPA receptor partially.

Phytoestrogens, which can bind with estrogen receptor and produce estrogen-like effects, are a kind of nonsteroidal compound in plant. Phytoestrogens chemically include isoflavones, coumarins, lignans and other compounds. Phytoestrogens are selective estrogen receptor modulator, and have therapeutical effects on breast cancer, prostate cancer, cardiovascular disease, menopausal symptoms, osteoporosis and other disease, however, do not produce stimulatory hyperplasia effects on uterus, mammary glands and other tissues and organs with positive estrogen receptor. Long-term exposure or excessive use of phytoestrogens maybe affects male reproductive system and hematopoietic function of fetus. Some questions need to be further studied, such as evaluation criteria on biological activity, adverse effects, and action mechanism of phytoestrogen. This review covers plant sources, chemical structure, pharmacological activity and safety of phytoestrogens. It will provide a useful reference for intensive research and rational utilization the phytoestrogens.

Objective To examine the feasibility of using the serous-lined tunnel technique for orthotopic neobladder, continent cutaneous diversion and ureteral replacement by the intestinal segment. Methods In 31 patients of orthotopic ileal neobladder, the serous-lined tunnel techniques were used for antirefluxing ureteral implantation: In 13 patients of continent ileal pouch, the techniques were adopted for continent-valve construction and for uretersl implantation: In 3 patients (with lower ureteric cancer), the same techniques were applied for constructing the ileal ureters with a proximal antirefluxing mechanism. Results With a mean follow-up of 27 mon( 12-132 mon), 88 ureters implanted into ileal neobladders or continent pouches functioned well with neither obstruction nor reflux: 12 in 13 continent valves functioned well with no incontinence. 3 patients with ileal ureters showed no ileo-ureteric reflux and had reduced hydronephrosis comparing to that of before surgery.Conclusions Ureteral reimplantation and continent valve formation achieved by adopting the serouslined tunnel technique provide satisfactory results. The versatility of the technique is obvious in the present experience and the creative application of the serous-lined tunnel technique should be possible in urinary reconstruction.
