Bone marrow mesenchymal stem cells (BMSCs) is a kind of multipotent adult stem cells,which is one of the most important seed sources of tissue engineering.Microgravity has inhibitory effects on osteogenic differentiation of BMSCs,which will cause bone mass reduction and changes of bone micro-structure that finally lead to osteoporosis.This process is regulated by multiple signaling pathways such as mitogen-activated protein kinase (MAPK) pathway,Notch pathway and Wnt/β-catenin pathway which co-regulated BMSCs osteogenic differentiation under microgravity.Studying the effects of microgravity on BMSCs into osteogenic differentiation can clarify the mechanism of bone loss,put forward new targets for the treatment of diseases and provide a useful reference for the development of China's space industry.

Objective To evaluate the effects of traspupillary thermotherapy (TTT) for the treatment of central exudative chorioretinopathy (CEC). Methods Twelve eyes of 12 patients who suffered from CEC were treated by using a diode laser at 810 nm. A variable spot size of 0.5 mm 2 0 mm was used depending on the size of choroidal neovascularization (CNV).The treatment was initiated in one spot for 55 to 60 seconds duration at a power range between 200 350 mW, and the treated area revealed no visible color change to a light gray appearance. Preoperative and postoperative fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in 10 of the 12 eyes. Results The visual acuity in all eyes was improved to different degree over a period of 3 10 months. Five or more lines improvement measured by Snellen chart in visual acuity was found after the treatment in 4 eyes, three to five lines in 5 eyes and one to two lines in 3 eyes. All eyes demonstrated decreased or vanished exudation in FFA. CNV disappeared or decreaced in 8 eyes and remained nochange in 2 eyes in ICGA. Conclusion TTT is obviously effective in treating CEC.

Conclusion The high expression of Runx2 in dedifferentiated chondrosarcoma is involved in the occurrence and development of dedifferentiated chondrosarcoma.

Objective:To study the effects of Jiaweitaohechengtang on expression of?-SMA protein in hepatic fibrosis rats induced by CCl4.Methods:Hepatic fibrosis models were induced by CCl 4 .All the experimental rats were divided into six groups:normal control group,model control group,colchicine positive treatment group,jiaweitaohechenqitang groups with high- dosage,medium-dosage and low-dosage.Drugs were given to rats for 8 weeks by intragastric administration.Scores of hepatic fibrosis were assessed with semiquantitive scoring system(SSS)through tianlanghong staining.Protein expression levels of ?-smooth muscle actin(?-SMA)were determined with immunohistochemical steining method.Results:SSS in model control group were higher than those in normal control group,but lower than those in three treatment groups with jiaweitaohechengqitang. Compared with nornal control group,the protein expression levels of?-SMA in liver tissues in model control group increased markedly,but decreased when it was compared to jiaweitaohechengqitang groups.There was a significant difference between model control group and three treatment groups.Conclusion:Jiaweitaohechengqitang has therapeutic effects on hepatic fibrosis.The mechanism may be ralated to the inhabitition of the activation of HSC.

AIM To study antitumor activity of the extract denominated as UAP(Uric Antitumor Peptides isolated and purified from normal human urine). MOTHODS Proliferation inhibition assay was examined by cell counting and MTT method. Experiments in vivo were tested by treatment on tumor mice and acute toxicity on healthy mice. RESULTS UAP exerted strong dose dependent inhibition on the proliferation of three tumor cell lines, but not human normal leucocytes. Treatments on tumor mice show that UAP effectively inhibited tumor growth of mice HAC hepatoma, mice Lewis lung carcinoma and mice S 180 sarcoma with apparently dose dependent effect. Acute toxicity proved that UAP had very low acute toxicity in mice with LD 50 = 2 137 13 mg?kg -1 . CONCLUSION UAP has strong antitumor activity in vitro and in vivo. This provides a promising alternative antitumor treatment.

Objective To explore clinical feasibility of liver transplant from child of brain death to adult, to summarize the clinical experiences that a child of brain death transplants liver to an adult. Methods The recipient was a 39-year-old woman patient with primary hepatic carcinoma and posthepatitis cirrhosis (decompensation stage); while the donor was a 8-old-year child of brain death because of brain neoplasms. Donated liver was gained by the method of en bloc multivisceral procurement in a short time; the operative method was classic orthotopic liver transplantation. The postoperative managements included immunosuppression, prevention of infection, hepatic protection, and other relevant supports etc. Results The transplantation operative duration was 6 hours, after which not only did the recipient survive but also her body functioned well including the liver part, with no severe postoperative complications. Conclusions The technology of transplanting livers from children to adults is feasible. The key to ensure the success of transplant operation is systematic preoperative evaluation, excellent operative technique, and perfect postoperative treatment.

Osteoporosis (OP) is one of the bone metabolic diseases which seriously harms the health and lives of people. The main cause of OP is that the balance between bone formation and bone absorption, i.e. the balance of the bone remodeling process,is no longer exist. When the bone absorption dominates the process, it will lead to osteopenia, destruction of bone microstructure and increased rate of fracture. Previous studies have shown that casein kinase 2-interacting protein-1 (CKIP-1) plays an important role in the process of bone tissue proliferation and differentiation. It mainly interacts with Smad ubiquitination regulatory factor 1 (Smurf 1) to affect bone metabolism. This review analyzes and summarizes the impact of CKIP-1 on bone tissue osteogenic differentiation direction and its mechanism, which may provide new idea and research orientation for future clinical treatment of osteoporosis.
