Objective: To obtain the bFGF mimic peptide binding to FGFR via phage display, and to provide the base for developing peptide agonist of bFGF. Methods: Using Balb/c 3T3 cells as the target cells and COS-7 cells as the subtractive panning, the phage display heptapeptide library was biopanned for 4 rounds to obtain the single phage clones. The affinity and the specificity of the clones were assessed by ELISA. DNA sequencing was applied to further analyze the positive clones. Results: Twelve positive clones were selected from the enriched phages. A group of hydrophobic peptides containing a conserved motif, PR, was identified. Conclusion: Two bFGF mimic heptapeptides binding to FGFR were selected, which may be used as the candidates for bFGF agonist.

Objective To investigate the changes of neuroglobin (Ngb) expression in the CA1 hippocampus after cerebral ischemia and the effect of limb ischemic preconditioning (LIP) on it in young and aged rats. Methods SD rats aged 3 months and 21-23 months with permanently occluding bilateral vertebral arteries were randomly divided into cerebral ischemic group and LIP + cerebral ischemic group, respectively. The expression of Ngb mRNA and protein in the hippocampus were investigated by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot methods. The profile of delayed neuronal death (DND) of pyramidal neurons in the hippocampus CA1 was evaluated by using thionin staining under light microscope by determining the neuronal density (ND) and histological grade (HG). Results Ngb mRNA and protein expressions were 0.16±0.02 and 0.32±0.07, 0.52±0.04 and 0.91±0.06, 0.09±0.01 and 0.22±0.08, 0.21±0.01 and 0.66± 0. 06 in young cerebral ischemia group, LIP + young cerebral ischemia group, aged cerebral ischemia group and LIP + aged cerebral ischemia group, respectively. The expressions of Ngb mRNA and protein after cerebral ischemia for 8 minutes in aged rats were decreased compared with those in the young rats which suffered an identical cerebral ischemia with the aged rats (P<0.05). LIP up-regulated Ngb mRNA and protein expressions in both young and aged rats which suffered cerebral ischemia (P<0.05). However, the up-regulation of Ngb expression in aged rats was significantly less than that in young rats (P<0.05). Neuropathological evaluation showed that ND was 38.8±10.9, 171.5±16.9, 21.2±12.2 and 102.7±15.4 in young cerebral ischemic group, LIP + young cerebral ischemic group, aged cerebral ischemic group and LIP + aged cerebral ischemic group, respectively. It showed that obvious DND of pyramidal neurons was found in young and aged rats after cerebral ischemia. Although LIP effectively protected the pyramidal neurons in the CA1 hippocampus against DND normally induced by ischemic insult, the neuroprotection of LIP for aged rats was less effective than that for young rats. Conclusions The expression of Ngb and the up-regulation effect of LIP on the expression in aged rats are significantly decreased compared to those in young rats when the rats suffer cerebral ischemia. These differences may be one of underlying reasons why the aged rats exhibit severe DND after cerebral ischemia and why the neuroprotective effect of LIP is less in the aged rats than that in the young rats.

The way of "extracting-salting-chromatography" was used to purify the phycoerythrin and phycocyanin from Porphyra yezoensis in process scale-up.First,by comprehensive comparison of efficiency,the Sephadex G-25 was selected from four resins (Sephadex G-25、G-100、S-300 and CL-6B) as the best choice used in crude extract desalting of phycobiliprotein.Then the preparation process of phycobiliprotein was scaled-up with raw material(Porphyra yezoensis) increased from 1g to 20g,and finally to 400g.The results indicated that the yields of purified phycoerythrin and phycocyanin (absorption spectra purity above 3.2) increased during according to process scale-up,with 0.323% phycoerythrin and 0.148% phycocyanin obtained from 400g frozen Porphyra yezoensis blades respectively.It is no doubt that the process involved in the experiment is a potential way for large scale preparation of phycobiliproteins of high purity.

ObjectiveTo investigate the iodine nutritional status of pregnant women,newborn heel blood thyroid stimulating hormone(TSH) level and their relationship with urinary iodine(UI) level during pregnancy in Zhoupu and Kangqiao districts of Pudong New Area of Shanghai.Methods A total of 993 urinary samples(the first,second and third trimesters of pregnancy were 200 people,respectively),breast feeding(193 people) and non-pregnant women (200 people) in Zhoupu and Kangqiao districts of Pudong New area were collected from Apr 2009 to Dec 2010.Two hundred copies of neonatal heel blood samples were collected.Median of UI was measured by arsenic-cerium catalysis.TSH in neonatal heel blood was analyzed 72 h after birth by time resolved fluoroisnmunoassay(TRFIA).ResultsMedian UI of all pregnant women was 161.35 μg/L,and that in third trimesters of pregnancy( 126.35 μg/L) was lower than that of the first,the second,the breast feeding and non-pregnant women (178.80,180.50,167.90,163.40 μg/L,all P< 0.05).The percentage of UI level less than 150 μg/L in the third trimester[57.5%(115/200) ] was higher than that of the first[39.0%(78/200) ],the second[39.5%(79/200) ],the breast feeding [ 16.6% (32/193) ] and non-pregnant women [ 23.0% (46/200) ],respectively (all P < 0.05).The percentage of UI level higher than 300 μg/L in the first [9.0%(18/200)],the second[8.0%(16/200) ] and the third trimester [ 5.0% ( 10/200 ) ] of pregnancy was lower than that of the breast feeding [ 20.2% (39/193) ] and nonpregnant [20.5%(41/200) ] women,respectively(all P < 0.05).The level of neonatal heel blood TSH was(2.92 ± 1.83)mU/L,the range was 0.01 - 9.76 mU/L,11.0%(22/200) of the neonates heel blood TSH level(5 mU/L)exceeded the ratio of World Health Organization (WHO) standard ( < 3% ) suitable for iodine nutrition.Conclusions The overall level of iodine nutrition among pregnant women in Zhoupu and Kangqiao districts of Pudong New Area of Shanghai is in the appropriate range,but the pregnant women in the third trimester is in mild iodine deficiencies,and the neonates in these districts may be prone to iodine deficiency.Monitoring of iodine nutrition of pregnant women should be strengthened and iodine supplementation should be done scientifically.

OBJECTIVESTo observe the effects of renal ischemic postconditioning (RI-Post) on myocardial apoptosis in rabbits with acute myocardial ischemia and reperfusion.
METHODSAll rabbits were subjected to 60 minutes ischemia by left anterior descending coronary artery occlusion (LADO) and 6 hours reperfusion. The rabbits are randomly divided into 3 groups (n = 8 in each group): (1) Ischemia-reperfusion (IR): LADO and reperfusion without additional intervention; (2) RI-Post: after 60 minutes of LADO, the left renal artery was occluded for 30 seconds and reperfused for 30 seconds and repeated 3 times, then the coronary artery was reperfused for 6 hours; (3) Medication intervention (MI): 10 minutes before coronary reperfusion, rabbits were treated with PKC antagonist GF109203X (0.05 mg/kg, IV), followed by RI-Post treatment and 6 hours coronary reperfusion. Myocardial apoptosis was measured by TUNEL and the myocardial Bcl-2 and Bax protein expressions were assessed by immunohistochemistry.
RESULTSCompared with the IR group and the MI group, myocardial apoptosis was significantly reduced (P < 0.05) and the Bcl-2 protein expression increased (P < 0.01) while the Bax protein expression decreased (P < 0.05) in the RI-Post group.
CONCLUSIONSRemote renal postconditioning applied right before the onset of coronary artery reperfusion can reduce the myocardial apoptosis induced by myocardial ischemia and reperfusion and up-regulate Bcl-2 while down-regulate Bax expression possibly by activation of protein kinase C.
