Objective The aim of this study was to explore induction and differentiation of endogenous neural stem cells(ENSCs) in the hippocampus soluble factors(HSF) from the hippocampus of adult Wistar rats by mimicking an intracranial microenvironment. Methods After Wistar rats sacrificed, the hippocampus tissue was obtained in cold DMEM/F12. After centrigued and filtered, the HSF was stored at -20℃. The ENSCs was obtained from the hippocampus tissue of a neonate Wistar rat. Collected the tissue, digested and obtained the ENSCs. After we observed the morphology, the ENSCs were cultured in different concentration (0、50、100、200、400 μl/mL) of HSF for 6 days, and compared the expression of Nestin and CD133 by immunocytochemistry. Meanwhile,we compared the Nestin and CD133 protein by western blot. And then we explored the optimal concentration of HSF by the numbers of all groups on the second and sixth day. Furthermore, we did the differentiated experiment using the same concentration of HSF. Results The number of neurospheres in the 100 μg/mL group was significantly higher than those in the other groups on the 6th day. Immunofluorescence revealed that the neurospheres from ENSCs in the 100 μg/mL group more highly expressed nestin and CD133 than control. This result was confirmed by western blot analysis. The neurospheres can differentiate into glia-like cells in 100 μg/mL HSF and 1% FBS expressing GFAP, S100 and P75 NGFR by immunofluorescence. Conclusion These data indicated that HSF alone, mimicking a destination of ENSCs in vitro, could induce and differentiate neurospheres from ENSCs, as a new method to get NSCs and glia-like cells differentiated from ENCs to repair the diseases of center nervous system.

Objective To retrospectively investigate the influence of Shenyi Capsule maintenance therapy on inflammatory factors in patients with advanced NSCLC. Methods Thirty seven patients with advanced NSCLC, who had become palliative or stable after first-line treatment with combined Shenyi capsule chemotherapy, were intentionally assigned to treatment group (group A, 21 patients) and control group (group B, 16 patients). Shenyi capsule was given to group A (20mg p.o., bid) until appearance of deterioration or intolerance, while no special treatment was given to group B. Leukocytes, neutrophils, C-reactive protein, tumor necrosis factor α (TNF-α), interleukin-1β(IL-1β), interleukin-1α (IL-1α),interleukin-6(IL-6) and interleukin-10(IL-10) were tested by blood specimens taken respectively on 1st day and 90th day. Results There were no statistical differences (P>0.05) between the level of inflammatory factors on 1th day and 90th day in treatment group. In control group, however, TNF-α、IL-1β and IL-6 increased (P<0.001, P=0.032、P=0.001 respectively) and IL-10 decreased significantly (P=0.035). Furthermore, the level of TNF-α、IL-1β and IL-6 in treatment group were also higher (P<0.001, P=0.001, P=0.004 respectively), while IL-10 was lower (P=0.002)than control group on 90th day. There were no statistical differences(P>0.05)between the two groups in the level of IL-1α, leukocyte, neutrophils or C reactive protein on 1th day and 90th day. Conclusion Shenyicapsule maintenance therapy could lower the expression of TNF-α、IL-1β and IL-6 in patients with advanced NSCLC, which indicates that the regulation of inflammatory reaction may be one of the mechanisms of inhibition from NSCLC progression in Shenyi capsule maintenance therapy.

Objective To construct a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem) and establish a nude mouse model of breast cancer with hepatic metastatic. Methods A gemcitabine-resistant variant of the breast cancer 4T1 cell line was induced by gradually increasing the concentration of gemcitabine; this variant is referred to in this study as 4T1/Gem. The proliferation suppression rates of 4T1 and 4T1/Gem cells were determined by using the CCK-8 essay to evaluate the drug resistance indices of the cell lines. Western blot analysis was used to detect P-gp protein expression. Under ultrasonography, a 4T1/Gem cell suspension was injected into nude mice to induce liver tumors. H&E staining was used to observe tumor pathology, and immunohistochemistry was used to detect the expression of ER, PR, HER-2, Ki-67, and P-gp. Results After 14 months of induction, a 4T1/Gem cell line is established successfully. The cell line can grow stably in culture liquid containing 40 μg/ml gemcitabine. The drug resistance index of 4T1/Gem is 788.547. Compared with the 4T1 cell line, the 4T1/Gem cell line can upregulate P-gp protein expression and successfully establish a nude mouse model of breast cancer with hepatic metastatic. ER, PR, and HER-2 proteins exhibit negative expression in the tumor tissue. The positive expression of P-gp and 10% of Ki-67 proteins is also observed. Conclusion This study successfully constructs a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem)and establishes a nude mouse model of breast cancer with hepatic metastatic, thereby providing an experimental basis for developing and treating a drug-resistant variant of breast cancer.
