1.Advances in allogeneic hematopoietic stem cell transplantation
Journal of Leukemia & Lymphoma 2016;25(4):249-252
In recent years,the application of haploidentical stem cell transplantation makes it possible for every transplant candidate to have a donor.Therefore,choosing best donor and dealing with transplantrelated complications,such as promoting engraftment,decreasing graft-versus-host disease and relapse,become key issues to improve transplant outcomes.The advances in allogeneic hematopoietic stem cell transplantation will be reviewed.
2.Research progress of bone morphogenetic proteins-9 induced periodontal ligament stem cells osteogenesis differentiation and it′s signal pathway
Journal of Medical Postgraduates 2015;(12):1327-1332
Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-β(TGF-β) superfamily and play critical roles in skeletal development, bone formation and stem cell differentiation.BMP9 is one of the most osteogenic BMPs, promoting osteogenesis differentiation of periodontal ligament stem cells ( PDLSCs) both in vitro and in vivo.Recently, signal transduc-tion studies have revealed that BMP-Receptor-Smads and BMP-Receptor-Mitogen activated protein kinase ( MAPK) play vital roles in BMP9 which promote PDLSCs osteogenesis differentiation.Several studies revealed that transcription factors closely associated with os-teogenesis differentiation are found in the downstream of the Smads and MAPK pathways.This review aims to summarize our current knowledge of BMP9-mediated osteogenesis by presenting recently completed works which may help us to further elucidate these path-ways.

Objective:To determine the mechanism of sunitinib-induced autophagy in renal cell carci-noma cells.Methods:MTS assay was applied to detect the cell viability alteration under the treatment of sunitinib (2,8 μmol /L).The sunitinib-induced autophagy as well as cell apoptosis was measured and compared after knocking down autophagy-related protein Beclin1 and microtubule associated protein 1 light chain 3 fusion protein (LC3)by RNA interference.The transmission electron microscope was used to observe the formation of autophagosomes in ACHN cells.The fluorescence microscope was used to mo-nitor distribution and aggregation of endogenous LC3-Ⅱ.The expressions of protein such as LC3-Ⅱ,the autophagic regulation molecules protein kinase B /mammalian target of rapamycin (Akt/mTOR)and the symbol of apoptosis poly ADP-ribose polymerase (PARP)were capable to be detected by immunoblotting assay.Results:Sunitinib was able to significantly trigger cell viability loss in the renal carcinoma cell ACHN,which was both in a concentration-dependent and time-dependent manner (P <0.05 ).After reducing the autophagy by knocking down Beclin1 and LC3,the number of cleavage of PARP was in-creased remarkably,whereas there was nearly not any cleavage in the mock group.By the transmission electron microscope,there were more autophagic vacuoles in ACHN cells after being administrated with sunitininb compared with the control.And the nuclear-to-cytosol translocation as well as aggregation of LC3-Ⅱ was presented after sunitinib treatment by the fluorescence microscope,which was the proof of the enhanced autophagy.According to the immunoblotting,sunitinib was able to increase the accumula-tion of LC3-Ⅱ.At the same time,the result of sunitinib combined with chloroquine,a drug which blocked the fusion of autophagosomes and lysosomes,demonstrated that the increasing amount of LC3-Ⅱwas due to the enhanced autophagy flux by sunitinib treatment in ACHN cells.However,phosphorylation of Akt as well as mTOR was decreased at the same time.The rapamycin (mTOR inhibitor)or knocking down Akt subunits could change the sunitinib-induced LC3-Ⅱ accumulation,whereas overexpression of Akt subunits decreased the autophagic flux,indicating that Akt/mTOR was the target of sunitinib in auto-phagy.Conclusion:Sunitinib induced autophagy via suppressing Akt/mTOR pathway,and the auto-phagy was involved in apopotosis.

Post stroke depression (PSD) is a common complication after senile cerebrovascular diseases. It influences both physical and mental health of the elderly severely. So, the attention should be paid to not only the medical cares but also the function and mental rehabilitation, in order to improve the qualities of PSD patients' lives and decrease the death rate.

Objective To evaluate the effect of penehyclidine hydrochloride (PHC) on the level of angiopoietin-1 (Ang-1) and tyrosine kinase receptor-2 (Tie-2) during endotoxin-induced acute lung injury (ALI) in rats.Methods Forty adult male Sprague-Dawley rats,weighing 180-220 g,were randomly divided into 4 groups using a random number table (n =10 each):control group (group C),ALI group,low-dose PHC group (group L-PHC) and high-dose PHC group (group H-PHC).ALI was induced with iv injection of lipopolysaccharide 5.0 mg/kg via the tail vein.In L-PHC and H-PHC groups,PHC 0.6 and 2 mg/kg were injected,respectively,via the tail vein at 1 and 24 h after lipopolysaccharide injection.The rats were sacrificed at 48 h after the initial injection of PHC to measure the lung water content,protein concentration in bronchoalveolar lavage fluid (BALF),and the expression of Ang-1,Tie-2 and phosphorylated Tie-2 in lung tissues.The morphological changes of lung tissues were observed under light microscope and the ultrastructural changes of alveolar epithelial barrier under transmission electron microscope.Results Compared with group C,the lung water content and protein concentrations in BALF were significantly increased,and the expression of Ang-1 and phosphorylated Tie-2 was down-regulated in the other three groups (P < 0.05).Compared with group ALI,the lung water content and protein concentrations in BALF were significantly decreased,and the expression of Ang-1 and phosphorylated Tie-2 was up-regulated in H-PHC group (P < 0.05),and no significant changes were found in the parameters mentioned above in group L-PHC (P >0.05).The damage to lung tissues was significantly reduced in group H-PHC as compared with group ALI.Conclusion PHC can improve the permeability of pulmonary microvascular and reduce injury to alveolar epithelial barrier,thus ameliorating endotoxin-induced ALI in rats,and the effect is dose-related and up-regulation of Ang-1 expression and inhancement of Tie-2 activity are involved in the mechanism.

Aim To investigate the effects of PLCε on the invasion and migration of human osteosarcoma cancer cells U2OS. Methods RNA interference ( RNAi) was used to inhibit PLCεexpression, and the proliferation of cancer cells was measured by CCK-8 assay. The migration of the cells was measured by scratch wound healing assay and migration chamber as-say. Gelatin zymography was performed to measure the MMP2 activities in U2OS cells. Results PLCε ex-pression was suppressed by siRNA. CCK-8 assay showed that PLCε had no effect on the proliferation of cancer cells. PLCε knockdown inhibited cell invasion and activities of MMP2 . Conclusion PLCε knock-down can inhibit the migration and invasion of human osteosarcoma cancer cells U2OS.
