In recent years,cellular immune therapy represented by antigen-chimeric receptor T cells (CAR-T) has made a great breakthrough in the treatment of hematological malignancies.T memory stem cells (TSCM) and central memory T cells (TCM) can be used as most powerful carrier for T cell immunotherapy,however,how to regulate their differentiation in vitro and in vivo as well as how to construct a strong treatment system while without potential side effect become quite interesting.This article summarized the studies from the 58th America Society of Hematology Annual Meeting regarding to values and associated research progress about TsCM and TCM in hematological malignancies.

ObjectiveTo observe the protective effect of tetrahydroxystilbene glucoside (TSG) on rats' hippocampal neuronal damage induced by glutamate (Glu) in the culture.MethodsHippocampus was isolated from newborn SD rats and dispersedly cultured in the medium for 9 days. Neurons were incubated with TSG (5—100μmol/L) for 24h, the cells were washed twice with Lock's solution without Mg2+,then Glu 500 μmol/L was added. Thirty min later, the reaction was terminated by washing the monolayer cells twice with the Lock's solution and then cultures were kept at 37℃ for 24h. Cell viability was measured by MTT method and cell membrane damage was determined by LDH leakage; with Fluo-3/AM as an intracellular calcium indicator and added into the bathing medium, fluorescent intensity of intracellular free calcium were observed through laser scanning confocal microscopy (LSCM).ResultsAfter the treatment with 5—100μmol/L TSG for 24h, the decrease of cell viability and the increase of LDH leakage caused by Glu was obviously resisted dose dependently. TSG inhibited increase of Ca2+ in cytoplasm, compared with model group.ConclusionTSG can significantly promote the cell viability and reduce the cell membrane damage in Glu treating hippocampal neurons. The neuroprotective activities of TGS is mediated by inhibiting Ca2+ overload in cytoplasm.

Objective　To study the effect of rehabilitation training on the expression of Fos in the central nervous system(CNS) of rats with cerebral infarction. Methods　60 SD rats were made as cerebral infarction models and divided into 2 groups at random 24 hours later: rehabilitation group was given balancing, grasping, rotating and walking and other trainings everyday, while immobiligation group was fixed in cages. Immunohistochemistry was used to detect the Fos expression 1 d, 7 d, 14 d, 21 d and 28 d after infarction respectively. Results　Fos-positive immune reaction appeared in cortex,thalamus, hypothalamus, reticular form and posterior gray horn of the spinal cord of both groups　.Rehabilitation group responded stronger than the immobilization group significantly (P<0.01).Conclusion　Rehabilitation training can activate cortical neurons around the infarted focus and in its opposite side of the CNS, and thus promote the recovery of rats' motor functions.

Objective BALB/C mice were inoculated subcutaneously with hepatoma 22 (H22) cells, and the treatment effect of thalidomide and intratumor injection of ethanol extract of Scutellaria Barbata (SB) on tumor growth were evaluated. Methods In vitro, mouse H22 liver cells were cultivated, and H22 cells in the logarithmic growth phase were tested. SB was extracted in the ethanol recirculation. A total of 28 BALB/C male mice inoculated subcutaneously with H22 cells were randomly divided into 4 groups, 7 mice per group. Group A:intragastric administration with thalidomide. Group B:SB intratumor injection. Group C:combination of thalidomide and SB with the same administration as Group A and Group B. Group D (control group):1% Ethanol 0.2～0.5 mL intratumor injection. Tumor volumes of four groups were observed and the tumors were weighed. The microvessel densities (MVD) of all transplantation tumors were measured by immunohistochemical staining with anti-CD31 monoclonal antibody. Results There were statistically significant differences between Group C and Group A (P 0.05). The studies showed statistically differences between Group C and Group A (P
