The cloning of promoter is important for studying the genetic engineering and the regulation of gene expression in plants. Two promoters Os772 and Os359, which are predicted to be highly expressed in the endosperm of rice from the EST database were cloned. After construction of the Os772∶∶GUS and Os359∶∶GUS expression vectors, they were transformed into rice. X-Gluc staining of transgenic plants showed that Os772 and Os359 can promote GUS gene expression in matured endosperm but not in root, stem, leaf and flower. This result indicates Os772 and Os359 are two rice endosperm-specific promoters.

Objective To examine whether ghrelin has beneficial effect on survival of pancreatic INS-1 beta cell.Methods Rat INS-1 cells were cultured separately in 5.6 mmol/L glucose (NG group),33.3 mmol/L glucose (HG group),33.3 mmol/L glucose plus 10 nmol/L acylated ghrelin (HG+AG group),and 33.3 mmol/L glucose plus 10 μmol/L unacylated ghrelin(HG+UG group).After being incubated for different hours,cell suvival rate was determined by MTT.Activity of caspase-3 was estimated by spectrophotometry,activity of GRP78,and cytochrome c was analyzed by confocal microscopy.Results Both acylated ghrelin and unacylated ghrelin inhibited the rise in activity of GRP78,caspase-3,and cytochrome c induced by sustained high glucose.Conclusions These findings indicate that ghrelin is able to inhibit endoplasmic reticulum stress and mitochondrial dysfunction of INS-1 β-cell caused by persistent high glucose,and the effect of ghrelin is not affected by acylation.

0.05)significant difference in 30 days (P0.001) between trunks groups and branches groups.Conclusion For the pationts with hypersplenism arteries were two or three branches,the PSE operation in the splenic arteriosus branches should be done,if splenic arteries were no truncus or truncus obvious crooked causing to introduce the catheter difficuty,the PSE operation in the splenic arteriosus truncus should be done.

Objective To investigate the effect-site concentration for 50% of maximal effect (EC50 )of propofol required for loss of consciousness and onset of burst suppression and to assess the effect of target-control infusion(TCI)of remifentanil on these EC50 of propofol.Methods Sixty patients undergoning general anesthesia for scheduled surgery were randomly divided into 2 groups (n=30):group R received TCI of remifentanil with a target concentraton of 4 ng/ml 10 minutes before TCI of propofol,which started at a target plasma concentration of 1μg/ml and then increased by 1μg/ml step every 1 minute until the burst suppression ratio reach to 15%.Group N received a mock TCI of saline instead of remifentanil and the other procedures were as same as group R.During this,all patients were assessed by modified Observ-er’s Assessment of Alertness/Sedation (OAA/S)scale,the loss of consciousness was definited by modified OAA/S values less than 2,the onset of burst suppression was definited by 15% of burst suppression ratio. Results The EC50 of effect-site concentration of propofol required for loss of consciousness and onset of burst suppression were 2.35 (95%CI 2.29-2.41)and 6.31 (95%CI 6.13-6.47)μg/ml respectively.The EC50 of propofol required for loss of consciousness was decreased to 1.73μg/ml by TCI of remifentanil,but the EC50 of propofol required for onset of burst suppression did not changed by TCI of remifentanil. Conclusion TCI of remifentanil could decrease the EC50 of propofol effect-site concentration required for loss of consciousness but has no effect on the EC50 of propofol required for onset of burst suppression.
