Objective To investigate the potential effects of rosuvastatin on white matter lesion and spatial memo?ry function in chronic hypertensive rats. Methods Fourty-nine male Sprague-Dawley rats were randomly divided into sham-operation group, vehicle-treated group, and rosuvastatin-treated group (10 mg/kg).A model of stroke-prone reno?vascular hypertensive rat (RHRSP) was induced by using the two-kidney two clip method in the vehicle-treated group and the rosuvastatin-treated group. Blood pressure was monitored regularly. Morris water maze experiment was conduct?ed to assess spatial memory function. Luxol fast blue stanning was used to examine the degree of leukoaraiosis. Immuno?fluorescence and electron microscopy was used to detectβ-amyloid deposits. TUNEL staining was used to assess apopto?sis. Results The blood pressure of RHRSP increased progressively after operation.Blood pressure was significantly high?er in RHRSP than in sham-operation group (P<0.01). The escape latencies of the rosuvastatin-treated group were mark?edly shorter in RHRSP than in sham-operation group (P<0.01). The numbers of crossing hidden platform in the 3 groups of rats were 4.55±1.23, 1.00±0.80 and 3.79±0.95 times. There were significantly differences in numbers of crossing hid? den platform among three groups (P<0.01). Luxol fast blue stanning showed that the grading scores for WML were lower in the rosuvastatin-treated than in the vehicle-treated group (P<0.01). Rosuvastatin significantly decreased the burden of Aβdeposits(17.47±3.59 vs. 4.42±1.57,P<0.01)and the TUNEL+cells(37.84±4.73 vs. 14.42±2.43,P<0.01)in the fron?tal cortex when compared with the vehicle-treated group. Conclusions Rosuvastatin may ameliorate spatial memory func?tion through attenuation of white matter lesion, Aβdeposits and apoptosis .

Objective To investigate the gender difference of the plasma lactic acid(LA) levels in type 2 diabetics with normal renal and hepatic function, and the effect of metformin on LA levels in the difference gender. Methods A total of 1 021 type 2 diabetic inpatients with normal renal and hepatic functions were collected,including metformin treatment group (213 males and 210 females) and metformin non-treatment group (299 males and 299 females). LA was measured with enzyme-electrode assay. Fasting plasma glucose ( FPG), creatinine ( Cr), and alanine aminotransferase ( ALT) levels were determined. Results LA level in metformin treatment group was significantly higher than that in metformin non-treatment group [ (1.32±0.53 vs 1.14±0.49) mmol/L,P<0.01],and 61 cases had hyperlactacidemia but no lactic acidosis was found. Spearman correlation analysis showed that LA level was positively associated with gender,metformin, and body mass index( BMI) apart from Cr and ALT( P<0.01). Multivariate logistic regression analysis showed that gender,Cr,ALT,and metformin were independent correlated factors of hyperlactacidemia. LA levels in females were higher than those of males in the whole group and two groups treated or not treated with metformin (all P<0. 05 ). LA levels in females were higher compared to male in Cr and ALT subgroups,as well as age subgroups,especially with age younger than 45 years old (P=0.021). Conclusions There is gender difference of lactate level in diabetic patients,and the effect of metformin on the plasma lactate levels of different gender is varied. The plasma LA level in females,especially those approaching menopause,are prone to hoist.

Objective To construct the eukaryotic expression plasmid containing glyceraldehydes-3-phosphate dehydrogenase (GAPDH) and cysteine protease inhibitor ( CPI ) gene from periodic Brugia malayi (Bm) and to lay foundation for studying multivalent vaccines. Methods Total RNA was extracted from periodic Bin. The BmGAPDH and BmCPI genes were amplified by RT-PCR. The PCR product was cloned and then subeloned into eukaryotic recombinant plasmid vector pcDNA3.1 (+). pcDNA3.1 (+)/BmGAPDH/BmCPI was constructed. The recombinant plasmids were screened and identified by digestion with restriction enzyme and PCR amplification, and were transformed into HeLa cell subsequently. The transient expression of BmGAPDH and BmCPI were examined by RT-PCR. The expressed protein was identified by sodium dodeeylsulphate-polyacrylamide gel electrophoresis(SDS-PAGE). Results Two specific bands of around 877 bp of BmGAPDH and 621 bp of BmCPI were amplified, consistent with the expected value. The same bands were obtained by double restriction enzyme digestion of recombinant plasmids or PCR using recombinant plasmid as template. BmGAPDH and BmCPI mRNA were highly expressed in transfeeted HeLa cell. The relative molecular mass (Mr) of the recombinant protein was about 54 × 103. Conclusion The recombinant eukaryotic expression plasmid pcDNA3.1 (+)/BmGAPDH/BmCPI has been constructed successfully and the protein is expressed correctly in mammalian cell.
