In order to explore the dormancy physiological and biochemical mechanism of Paris seeds, the seed embryo growth courses, and the dynamic change of 5 enzymes, include SOD, POD, CAT, MDH, G-6-PDH were measured during variable temperature stratification. The results indicated that Paris seeds embryo grew quickly after 40 d in warm-stratification (18 ± 1) °C, at the meantime the metabolic activity was significantly strengthened. These facts showed that Paris seeds turned into physiological after-ripening process. After 60-80 d, the morphological embryo after-ripping process basically completed, and the following cold-stratification (4 ± 1) °C furthered Paris seed to finish physiological after-ripening. After 40 d, the activity of MDH decreased while G-6-PDH increased significantly. This showed that the main respiratory pathway of seed changed from TCA to PPP, which benifited breaking seed dormancy. In the whole period of stratification process, the activity variation of SOD and CAT was insignificantly and the activity of POD was enhanced significantly after shifting the seed in cold stratification process. This showed that SOD, CAT had no direct effects on breaking Paris seed dormancy but keeping the seed vigor, while the POD might involve in the process of Paris seed dormancy breaking.

AIM:To be one of the primary cause injury to multiple sites of ocular of glaucoma which affects over 70 million people worldwide. We applied data mining techniques, linear and the matrix operations, efficiently calculated the network and estimated the possible function of the“node” genes of the retina and optic of glaucoma, in order to provide new thought and method on the pathogenesis of glaucoma.
METHODS: The data in this study is from Gene Expression Omnibus ( GEO ) which belong to Nation Center for Biotechnology Information ( NCBI) , the quality of the raw data CEL files was processed and analyzed by the Expression software which belong to Affymetrix Inc. , Santa Clare, CA, USA. Significant analysis method ( SAM) which base on the T test was used to identified the significant genes. Based on GRNInfer and Gvedit soft we set up gene networks of optic and retina of mice and further more enriched analysis which based on DAVID and MAS3. 0 online software were processed.
RESULTS:The analysis between the group of the optic nerve heads and retinas in different stage of glaucoma showed that the amount of significant different expressed genes in the optic never head group increased significantly comparing with the group of retina in the early stage of glaucoma, the analysis of the genes network construction show that:the node genes of optic nerve heads included Unc13c、Kif5a、TRPM1、PANX; and the node genes of retina include POU4F1, NEFL, BC03870, CALB2. Metabolic pathways enrichment analysis which based on MAS3. 0 online platform show that there was mainly the amyotrophic lateral sclerosis, tyrosine metabolism, melanogenesis, Nitrogen metabolism, Gap junction, Leukocyte transendothelial migration metabolism pathway enriched out in optic nerve head; and there was mainly amyotrophic lateral sclerosis, neurodegenerative disorders, prostate cancer, leukocyte transendothelial migration metabolism pathway enriched out in retina.
CONCLUSION:By understanding bioinformatics result, it seems optic were more sensitive than the retina to high intraocular pressure, and weather high expression of TYrp1 gene can be as a sensitive diagnostic item require more evidence back up. Functional enrich analysis of node gene showed that cytoskeleton reconstructed, molecular motor and nutrients transport function improve in optic; and in retina, the most prominent finding in retina was enrichment function modules were focus on regeneration, repairing and differentiation of cells, which remind that we should reinforce research on reparation of retina of primary glaucoma. Metabolic pathways enrichment analysis show that inflammatory response plays prominent place in optic and retina of primary glaucoma, because of the optic narrow and crowed anatomic shape, nutrient metabolism and substances transfer enrichment modules play an important role in optics of primary glaucoma.

Serum cytokine concentrations were determined in patients with Graves'disease(GD)before and after treatment of thiamazole.Serum soluble interleukin-2 receptor(sIL-2R)level was markedly raised before treatment as compared with normal subjects and returned to normal after 3 month therapy.Serum IL-8 level was lowered in GD patients and showed no change after 3 month therapy.No relationship between IL-8 and other markers was found.Serum IL-1?,IL-6 and TNF-?levels in GD patients showed no difference with those in normal controls.

OBJECTIVETransplantation of adipose-derived stem cells (ADSCs) is associated with potential risks of late complications including tumorigenesis due to the active proliferation of the cells. We aimed to test the effect of transplantation of ADSCs with suppressed proliferation by gamma irradiation in the treatment of thin endometrium in rats.

METHODSADSCs were isolated from female SD rats and identified by detecting the surface antigens with flow cytometry. After exposure to gamma irradiation at 0, 5 Gy and 10 Gy, the cells were examined for changes in colony-forming ability. Twenty-four female rats with chemically induced thin endometrium were randomized into 4 equal groups and at 6-8 h after modeling, the rats received intrauterine injection of non-irradiated ADSCs (group I), 5 Gy irradiated ADSCs (group II), 10 Gy irradiated ADSCs (group III), or PBS only (group IV). Endometrial pathology was analyzed with HE staining in these rats in the third estrus phase following the cell transplantation.

RESULTSThe ADSCs showed a complete loss of proliferative capacity after exposure to 10 Gy irradiation. After the cell transplantation, the endometrium thickness was thicker in group I and II than in group IV (P<0.01), but there was no significant difference between groups III and IV.

CONCLUSIONSGamma irradiation impairs the proliferative capacity of ADSCs in vitro. Exposure to 10 Gy irradiation causes a total loss of proliferation capacity of the ADSCs, which have no therapeutic potential; 5 Gy irradiation causes partial loss of proliferation capacity of the cells, which still retain the activity to promote endometrial cell regeneration.
