Compared with living spray method, it focused on the investigation of different inoculation methods, various inoculation concentration and the influence of different seeding age on soft rot-resistance in Jinxianlian. The results showed that (1) Inoculated with dropping connection, the difference of disease index between A. roxburghii and A. formosanus was grate, so that the disease-resistance could be obviously distinguished. (2) When the inoculation concentration was 1.0 x 10(7) cfu x mL(-1), the difference of disease index was relatively obvious and the disease-resistance could be differentiated well. (3) At the moment of 4-month seeding inoculation, a certain difference of the disease index between A. roxburghii and A. formosanus was existed, so, relatively, it could accurately reflect the resistance difference between various species. With the inoculation of dropping connection, A. roxburghii and A. formosanus of 4-month seeding age was put in the bacteria suspension of inoculation concentration of 1.0 x 10(7) cfu x mL(-1). The identification was taken up after 5 days in the incubator under the condition of 14 h daylight and 28 degrees C. The identification result was conformed with that of the living spray method. To investigate the identification method of in vitro evaluation of soft rot-resistance of Jinxianlian so as to provide the foundation for germplasm utilization and excellent cultivars breeding.

The mobilization efficiency of granulocyte colony-stimulating factor (G-CSF) and stem cell factor (SCF) to bone marrow mononuclear cells (MNCs) in mice was observed, and the changes of CXCL12/CXCR4 signal were detected in order to find out the mobilization mechanism of stem cells. Kunming mice were randomly divided into two groups. The mice in treatment group were subjected to subcutaneous injection of G-CSF at a dose of 100 mug/kg and SCF at a dose of 25 mug/kg every day for 5 days, and those in control group were given isodose physiological saline. The MNCs were separated, counted and cultured, and the colony-forming unit-fibroblast (CFU-F) was evaluated. CD34(+)CXCR4(+) MNCs were sorted by flow cytometry. The expression of CXCL12 protein in bone marrow extracellular fluid was detected by ELISA, and that of CXCL12 mRNA in bone marrow was measured by RT-PCR. The results showed that the counts of MNCs in peripheral blood and bone marrow were increased after administration of G-CSF/SCF (P<0.01). The factors had a dramatic effect on the expansion capability of CFU-F (P<0.05). Flow cytometric of bone marrow MNCs surface markers revealed that CD34(+)CXCR4(+) cells accounted for 44.6%+/-8.7% of the total CD34(+) MNCs. Moreover, G-CSF/SCF treatment induced a decrease in bone marrow CXCL12 mRNA that closely mirrored the fall in CXCL12 protein. In this study, it is evidenced that G-CSF/SCF can effectively induce MNCs mobilization by disrupting the balance of CXCL12/CXCR4 signaling pathway in the bone marrow and down-regulating the interaction of CXCL12/CXCR4.

Objective To assess the value of contrast-enhanced ultrasound (CEUS) on quantitative analysis of re?nal cortex perfusion in hypertensive rabbits model. Methods Hypertensive rabbit modal (n=10) were established by inject?ing N-nitro-L-arginin methylester (L-NAME). CEUS and Cystatin C (CysC) serum level analysis were performed at differ?ent time points:before and the 2nd, 4th, 6th and 8th week after injecting L-NAME. Time-intensity curve and area under curve (AUC) were analyzed quantatively while correlation of AUC and CysC were also analyzed. Results Serum level of Cys C in?creased significantly at the 6th week after L-NAME administration which is earlier than the increase of serum levels of Scr and BUN. AUC decreased at first then increased after L-NAME administration. Upon addition of L-NAME, rise time (RT) and peak intensity (PI) decreased while mean transit time (MTT), time from peak to one half (HPT) and time to peak (TTP) in?creased. Our study confirmed a positive correlation between AUC and Cys C (r=0.950, P<0.001). Conclusion Setting up rabbits model by L-NAME is convenient and reproducible, which is an useful tool in experimental study of preclinical and clinical phase of hypertensive renal injury. CEUS combining with CysC serum level analysis is considered as an effective technology for evaluating renal function in hypertensive patients.
