Objective To explore the effect of behavioral training on the differentiation of neural stem cells in the dental gyrus (DG) in rats with hippocampus infarction. Methods Seventy-eight Sprague-Dawley rats were randomized into infarction plus behavior training group, infarction group and control group. Photochemistry method was used to induce hippocampal infarction in rats of the infarction plus behavioral training group and infarc-tion group. At 1 day after surgery, Morris water maze training was used for infarction plus behavioral training group, free-movement without training was performed for infarction group. Double staining immunofluorescence was used to detect the co-expression of bromodeoxyuridine (BrdU) with neuronal nuclei ( NeuN ) or glia fibrillary acidic protein (GFAP) in the DG at different time points. Results Few BrdU/NeuN and BrdU/GFAP double staining cells were observed in the DG of control rats. In the infarction group and infarction plus behavioral training group the number of BrdU/NeuN and BrdU/GFAP double-stained cells increased in the DG on the opposite side compared with the control group on 14th, 21st, 28th and 35th days after surgery (P < 0.05 ). There observed significantly more BrdU/NeuN and BrdU/GFAP double-stained cells in the infarction plus behavioral training group than that in the infarction group on the 14th, 21st, 28th and 35th days after surgery ( P < 0.05 ). Conclusion Behavioral training can accelerate the differentiation of neural stem cells to neuron and astrocyte, by which to promote the re-covery of neural functions.

BACKGROUND:Due to the different transplantation time after myocardial infarction, the homing ability of bone marrow mesenchymal stem cels to damaged tissues as wel as the repairing role wil be very different. OBJECTIVE:To explore the optimal window time for the homing of bone marrow mesenchymal stem cels to the myocardial tissue after myocardial infarction. METHODS: Eighteen Chinese miniature pigs were modeled by the ligation of left anterior descending coronary artery. BrdU-labeled bone marrow mesenchymal stem cels were injectedvia the coronary artery at 1 day, 3 days, 1 week, 2 weeks, 3 weeks, 4 weeks after modeling, respectively. Then, the animals were kiled at 3 days after cel transplantation to detect the home of bone marrow mesenchymal stem cels in the infarct zone. RESULTS AND CONCLUSION:BrdU-labeled positive cels with brown nuclei were visible at 1 day, 3 days, 1 week, 2 weeks, 3 weeks, and 4 weeks after myocardial infarction, especialy at 1 week after myocardial infarction (P < 0.05). It indicates that the best homing window for bone marrow mesenchymal stem cels was at week after myocardial infarction, when the stem cel transplantation is given to be able to promote myocardial repair.

Objective To investigate therapeutic autcomes of using telomerase inhibitors to treat cancer at the presumably most and least opportune circadian stages basing on our earlier study. Methods Twenty-four BALB/C nude mice were synchronized to a regimen of LD12:12 for 4 wk. Hepatic cancer cells (SMMC-7721) were implanted into both flanks of each mouse.Two weeks after transplantation,the hTERT-5'RZ was used to treat the hepatic cancer transplanted into the nude mice daily for two weeks,the injection times being either 9 or 21 HALO.Results The tumorinhibition ratio of mice treated at 21 HALO (65%) was statistically significantly higher than that of mice treated at 9 HALO (48%). Telomerase activity was also reduced to a greater extent in mice treated withhTERT-5'RZ at 21 than at 9 HALO, that was at the time of maximal circadian telomerase activity. Conclusion Injection of ribozyme targeted to telomerase during the tumor's DNA synthesis is associated with a betterinhibition of tumor growth and a better therapeutic outcome in hepaticcancer.
