ObjectiveTo observe and compare the efficacy of two types of microencapsulated rat islets xenotransplanted into diabetic mice. MethodsThe mice diabetic model made with injecting 3% Streptozotosin through tail vein. Four groups were assigned: control group, naked islet transplantation group, alginate-BaCl2 microencapsulated islet transplantation group, agarose-PSSa microencapsulated islet transplantation group.300 islets were transplanted under the renal envelope of each diabetic mice respectively. ResultsThere were no significant difference in mean level of the blood glucose before transplantation among four groups. One week after transplantation, the respective mean level of the blood glucose in four groups were (7.26±1.56) mmol/L in alginate-BaCl2 microencapsulated islet transplantation group, (7.14±1.04) mmol/L in agarose-PSSa microencapsulated islet transplantation group, (7.42±1.52) mmol/L in naked islet transplantation group and (22.54±1.24) mmol/L in control. There were significant difference between the two encapsulated islet groups and the other two groups. The survived period of the two encapsulated islet transplantation groups were longer than that of the other two groups. The survived period of the alginate-BaCl2 microencapsulated islet transplantation group was longer than that of the agarose-PSSa microencapsulated islet transplantation group (92 d vs 56 d),the same as the time of keeping nomal blood glucose level (76 d vs 41 d). ConclusionMicroencapsulated rat islets with this two materials can survive in diabetic mice with their biological activity, and the alginate-BaCl2 microcapsules are better than the agarose-PSSa microcapsules.

Objective To investigate the correlation of the middle cerebral artery stenosis (MCAS) and the mild cognitive function impairment (MCI),and the clinical efficacy of statins in patients with MCI. Methods Six hundred and thirty-six patientse,who received transcranial color doppler ultrasound (TCD)assay, were enrolled in our hospital hospitalization or outpatients. The simple mental state examination (MMSE) and clinical dementia rating scale (CDR) were used as cognitive function assessment indexes. Forty-four cases of MCI with MCAS and 58 cases of MCI with NMCAS were used as the treatment group , who received the atorvastatin 20 mg every day , 56 cases of MCI with NMCAS were used as the control group , who only received the routine and basic diseases treatment. One yearlater,we determined the changes of MMSE and CDRagain. Results We detected 124 patients with MCAS, 512 patients with NMCAS, and 44 cases of MCAS patients with MCI, the prevalence was 35.5%,114 cases of NMCAS in patients with MCI, with the prevalence of 22.3%, the prevalence between the two groups was statistically different. One year later, the patients in the treatment group, MMSE score was improved, the score of MCI of the MCAS group improved more significantly. Conclusion The middle cerebral artery stenosis correlated with the occurrence of MCI. Atorvastatin could improve cognitive function in patients with MCI, especially for MCI which was caused by middle cerebral artery stenosis.

Salvianolic acid A (Sal A) is one of the most effective compounds isolated from the root of Salvia miltiorrhiza. Up to now, several studies regarding the pharmacokinetic profiles of Sal A have been reported, however there is no such study reported in monkeys, the species which is more similar to human. The aim of this study is to develop a LC-MS method for the determination of Sal A in monkey plasma and apply it to the pharmacokinetic studies of monkeys. After single intravenous administration of Sal A, the plasma concentration-time curves were observed and the main pharmacokinetic parameters were calculated. The plasma concentration at 2 min (C2 (min)) values were (28.343 ± 6.426), (45.679 ± 12.301) and (113.293 ± 24.360) mg x L(-1) for Rhesus monkeys treated with Sal A at 2.5, 5 and 10 mg x kg(-1). The area under the concentration-time curve (AUC(0-∞)) values were (3.316 ± 0.871), (5.754 ± 2.150) and (13.761 ± 2.825) μg x L(-1) x h, respectively. Furthermore, this method was improved and applied to the simultaneous determination of Sal A, Sal B and Sal C, which provided useful information for preclinical studies and clinical trials of Sal A, Sal B and Sal C.
