AIM To investigate the possible role of the mitochondrial transmembrane potential (??m) and caspase 3 in arsenic trioxide(As 2O 3)-induced apoptosis of cancer cells. METHOD Namalwa, SGC7901 and Bcap37 cell lines were used as in vitro models. Apoptosis was confirmed by sub-G 1 cells content as well as phosphatidylserine(PS) externalization. The ??m was detected on flow cytometry through double staining of Rhodamine 123(Rh123) and popidium iodide(PI). In addition, the effect of DEVD-CHO, a selective inhibitor of Caspase 3, on As 2O 3-induced apoptosis was studied. RESULT The As 2O 3-induced apoptosis closely associated with the externalization of the ??m and the activation of Caspase 3. As 2O 3 induced cells necrosis when Caspase 3 was inhibited. CONCLUSION As 2O 3 may selectively activates Caspase 3 after it induces externalization of ??m, which causes cancer cells apoptosis.

OBJECTIVE: To compare the pharmacokinetics and relative bioavailability between ganciclovir-chitosan eye drops and ganciclovir eye drops in rabbit eyes. METHODS: Japan big-eared rabbits were randomly assigned to the receive 50 ?L ganciclovir-chitosan eye drops (experiment group) or ganciclovir eye drops (control group) in both eyes. The rabbit tears,corneas and aqueous humor were collected at different time for the determination of drug concentration by RP-HPLC. The pharmacokinetics parameters were calculated as well. RESULTS: In the experimenal group,the half-life(t1/2) in tears,corneas and aqueous humor were 15.41,45.21,59.43 minutes,respectively versus 16.22,32.55,and 48.53 minutes in the control group. The Cmax were 2.03 ?g?mL-1 and 1.22 ?g?mL-1,respectively. In the experimental group,the AUC0→240 in tears,corneas and aqueous humor were 1.66,1.89,and 2.77 times those in control group. CONCLUSION: The bioavailability of ganciclovir-chitosan eye drops was significantly higher than that of ganciclovir eye drops.

Objective Our study is to observe the effects of conjugated equine estrogen (CEE) combined with medroxyprogesterone acetate (MPA) on hemorheology in postmenopausal women in order to evaluate mechanism responsible for the increase in the incidence of cardiovascular disease after menopause and also to provide proper instruction and advice of hormone replacement therapy (HRT) for postmenopausal women Methods 60 healthy postmenopausal women were assigned to 3 groups randomly, 20 cases in each group Group A: CEE 0 625 mg/d+MPA 2 mg/d+calcium carbonate co. (Ca D) 600 mg/d Group B: CEE 0 3 mg/d+MPA 2 mg/d+Ca D 600 mg/d Group C: Ca D 600 mg/d only served as control Measurements of hemorheological parameters were performed before and 6 months after treatment Results After 6 months of HRT, group A: blood viscosity under the shear rate of 94 5 s -1 dropped from (5 23? 0 37) mPa?s to (5 03? 0 43) mPa?s ( P 0 05) Conclusion Both different dosages of CEE have favor effects on blood viscosity and erythrocyte deformabillity, which could play the role in preventing cardiovascular disease in postmenopausal women

Objective: To optimize the formula of memantine hydrochloride sustained release pellets and investigate the drug release in vitro.Methods: Memantine hydrochloride sustained release pellets were prepared by a fluidized bed.The factors such as inlet air temperature, spray pressure and feeding rate were optimized by orthogonal tests.The Box-Behnken response surface methodology was used to screen the major influencing factors (ethyl cellulose aqueous dispersion, PEG 6000 and the coating weight) in the release of memantine hydrochloride.The coating formula and coating weight were optimized with the cumulative release rate of memantine hydrochloride in 2, 6,and 12 h as the response values.The drug release in vitro was also studied.Results: The optimum preparation parameters of the pellets were as follows: the inlet air temperature of 45℃, the spray pressure of 1.0 bar, and the feeding rate of 1.5 r·min-1.The best sustained release coating formula was as follows: the content of ethyl cellulose aqueous dispersion of 8.4%, the content of PEG 6000 of 2.3%, and the weight gain of sustained release layer of 16.7%.The memantine hydrochloride sustained release pellets had notable sustained release effect.Conclusion: Orthogonal tests and Box-Behnken response surface method can be used for the formula optimization of memantine hydrochloride sustained-release pellets.The established fitting model is simple with good predictability.
