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.

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.

Objective To discuss the value of network with real-time monitoring case in hospital. Methods Using the real time monitoring case of "No.1 Military Medical Project" and examining, analysis and evaluating. Results The quality of case and medical care were advanced obviously. Conclusion The scientification and standardization of case realized is propitious for hospital management.

After the problems in digitalizing ancient books on traditional Chinese medicine were analyzed, the principles that should be followed in their digitalization were pointed out according to its theories and practice.The platform for digitalizing them was constructed with《Collective Notes to Canon of Materia Medica》as an example, and its design ideas, framework, development model and functional modules were described.

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 develop long-term care demand assessment indicators for the disabled elderly in nursing home.Methods The assessment indicators were formulated based on literature review,semi-structured interviews and expert meeting.Then,Delphi technique was used to identify the indicators through two rounds of consultation among 23 experts.Results The response rates of two rounds consultation were 74.19％ and 95.65％,and the authority coefficients of experts were 0.850 and 0.905.The coordination coefficients of two levels of indicators in the second round were 0.600 and 0.269,respectively (P＜0.001).The long-term care demand assessment indicators for the disabled elderly in nursing homes consisted of 5 first-level indicators and 40 seeond-level indicators.Conclusion The longterm care demand assessment indicators for the disabled elderly in nursing home is reliable and scientific,which can provide references for further developing long-term care contents for the elderly in the nursing home and standardizing quality of long-term care.

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.

Objective To investigate the expressions of claudin-5 and claudin-10 in colorectal carcinoma(CRC) and its significance.Methods Pathological verified 50 colorectal tissue (CRT),25 colorectal adenoma (CRA),25 non lymph node metastasis CRC (non-LNM CRC) and 25 lymph node metastasis CRC (LNM CRC) were detected for the expression of claudin-5 and claudin-10 by immunohistochemical SP(streptavidin perdcidase) method.Results The positive expression rate of Claudin-5 was 82%,76%,68% in CRT,CRA,CRC,respectively.The positive expression rate of claudin-5 in different groups was not significantly different(X~2 =2.638,P＞0.05).claudin-5 expression was correlated with LNM (P＜0.05),but was not correlated with gender,age,tumor,location,differentiation,tumor diameter and serous membrane invasion(P＞0.05).The positive expression rate of claudin-10 was 54%,56%,72% in CRT,CRA,CRC,respectively.The positive expression rate of claudin-10 in different groups was not significantly different(X~2 = 3.839,P＞0.05).claudin-10 expression was correlated with tumor diameter,serous membrane invasion and LNM (P＜0.05),but was not correlated with gender,age,location and differentiation (P＞0.05).There was no significant correlation between claudin-5 expression and claudin-10 expression in CRC (r = 0.050,P = 0.732).Conclusions claudin-5 and clandin-10 are expressed in CRT,CRA,and CRC.They are not involved in CRC occurrence,claudin-5 and clandin-10 abnormally expressions are significantly associated with the incidence of LNM.Meanwhile,claudin-10 expression is correlated with tumor diameter and serous membrane invasion.There was no significant correlation between claudin-5 expression and claudin-10 expression in CRC.
