Objective To search for the effect of benidipine,a kind of Ca2+ blocker,on NO and ET-1 of patients with coronary heart disease.Methods Benidipine(2~4 mg/d)were given to the patients with coronary heart disease diagnosed definitely for 8 weeks.Forty healthy candidates were enrolled in the control group,and their morning fasting blood were tested for NO and ET-1 levels at the 4th,8th week in order to compare with the control group.Results Blood NO level of CHD patients was lower and blood ET-1 level was higher than the control group remarkably.After treatment NO level was increased and ET-1 level was decreased separately.Conclusion Benidipine can increase NO level and decrease ET-1 level,which demonstrated the protective effect of benidipine for endothelia.

Objective To investigate the effect of rosiglitazone (ROS),a peroxisome poliferator- activated receptor (PPAR)?ligand,combined with all-trans retinoic acid (ATRA) on anti-angiogenesis of transplanted gastric cancer in nude mice,and to explore the mechanism of anti-angiogenesis prelimina- rily.Methods The model of xenograft tumor in nude mice were established by inoculating human gastric cancer cells line MGC803 (lower differentiated) into the back of nude mice subcutaneously.The cancer- bearing nude mice were divided randomly into 5 groups:group 1 (n=6) with no treatment;ROS treat- ment (group 2,n=6),ROS combined ATRA treatment including:low dose treatment (group 3,n= 6),moderate dose treatment (group 4,n=6) and high dose treatment (group 5,n=6).After treated for forty days,the volume change of tumor and tumor inhibition rates were observed.The expression of CD34,vascular endothelial growth factor (VEGF) in grafts were detected by immunohistochemical and calculated the difference of MVD.The mRNA expression levels of VEGF,HIF-l?were detected by RT- PCR assay accordingly.Results①The volume of tumor was significantly decreased in ROS treatment group compared with group 1 (P＜0.01).The tumor inhibition rates of group 2 were similar to group 3 (P＞0.05).With the increasing of the dose of ROS the tumor inhibition rates were increased.They were dose-dependent in specified dose-range.②ROS could inhibit angiogenesis of xenograft tumor and depress expression of mRNA of VEGF and HIF-l?.When ROS combined with ATRA,the increasing of dose of ROS,inhibiting angiogenesis of tumor and depressing expression of mRNA of VEGF and HIF-l?were found (P＜0.05).Conclusion ROS (25 mg?kg?2 d~(-1)) can inhibit the growth of tumor,and ROS combined with ATRA can further inhibit the growth of tumor,which may be through the path of PTEN by inhibiting the angiogenesis of tumor

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by memory loss and cognitive decline. The pathological eatures of Alzheimer's disease are abnormal deposition of amyloid beta-peptides (Aβ), neurofibrillary tangles, cholinergic deficits, and loss of synaptic processes and dendritic spines. Senescence accelerated mouse prone 8 exhibits age-related deficits of learning and memory from an early age, tau protein phosphorylation, neurotransmitter changes, synaptic structure and function disorders, circadian rhythm disorders,as well as gene expression and many other characteristic changes, which are consistent with Alzheimer's disease pathological changes，and can be used as an ideal animal model for Alzheimer's disease prevention drugs development.

The experiment was designed to study the mechanism of increasing efficiency of Ligustrum lucidum steamed with wine. Rats in vivo with gastrointestinal perfusion model were used. The contents of salidroside and specnuezhenide in the fluid of gastrointestinal perfusion of rats were measured by HPLC at different time points after dosing. Then the K(a) and absorption percentage were calculated. Specnuezhenide could be detected in the fluid of gastrointestinal perfusion of specnuezhenide. The K(a) of the specnuezhenide and salidroside in the fetal intestines are 0.055 3 and 0.144 2 h(-1) respectively and the total absorptivity are 24.46% and 60.14% respectively after 4 hours. The K(a) in the stomach are 5.70 and 8.26 h(-1) respectively and the total absorptivity are 34.21% and 47.23% respectively after 4 hours. The experiment proved that specnuezhenide can be metabolized into salidroside which is more beneficial for gastrointestinal absorption. The experiment proved that specnuezhenide can be metabolized into salidroside both in the rat's stomach and the fetal intestine and compared with the specnuezhenide salidroside is more conducive to gastrointestinal absorption. The results suggested that the increasing efficiency on liver and kidney of L. lucidum steamed with wine has business with the fact that Specnuezhe nide is more conducive to the body after it is changed into salidroside.
