Objective To study the effect of SDF1/CXCR4 and FN/?1 integrin modulated by curcumin on the adhesion and migration of B lymphoma Raji cell and to explore the mechanism of curcumin to inhibit the invasiveness of lymphoma.Methods The experiment consisted of eight groups: Control,FN,SDF,FN+anti-?1 integrin,SDF+anti-CXCR4,curcumin+FN,curcumin+SDF.Adhesion assay and migration assay were used to detect the difference of invasiveness among different groups.Results In vitro,SDF1 and FN can increase the adhesion and migration of Raji cells,which can be blocked by ?1 integrin antibody and CXCR4 antibody.Curcumin can inhibit the adhesion and migration of Raji to FN in a dose-dependant manner.Low dosage curcumin had minimal effect on the adhesion and migration of Raji induced by SDF except that 25?mol/L curcumin can inhibit the adhesion and migration of Raji.Conclusion FN/?1 integrin and SDF1/CXCR4 pathway play important roles in the adhesion and migration of Raji cells.Curcumin can decrease the invasiveness of Raji cells through inhibiting FN/?1 integrin.It has good prospect of clinical application.

Culture environment is the key factor in the construction of dermal skin.It was investigated that the effects of the culture methods,including the static culture and spinner flask culture,and stir speeds on the cells proliferation,metabolism and distribution within collagenchitosan sponges.A higher cell density and specific growth rate was obtained with spinner flask culture versus static culture,especially,the 80 r/min spinner flask culture.The cell distribution in dermal substitutes from stirred culture system was more uniform than static culture,as well as that with increase of stir speeds in spinner flask.In summary,the spinner flasks culture with proper stir speed shows promise for the construction of dermal substitutes in vitro.

0.05).Conclusion Three Hybridoma cell lines which secrete the target antibodies with satisfied affinities and specificities have been successfully raised,which provides a basis to produce a domestic-made HCMVpp65 antigen diagnosis kit.

The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

BACKGROUND:There are few reports concerning effects of warming the yang and benefiting the marrow for the knee osteoarthritis on the expression of matrix metal oproteinase.
OBJECTIVE:To observe the effect of warming the yang and benefiting the marrow on the expression of matrix metal oproteinase in rabbit models of knee osteoarthritis.
METHODS:Of 96 healthy adult New Zealand rabbits, 72 rabbits were randomly selected for making rabbit models of knee osteoarthritis using plaster external fixation. After success model establishment, the rabbits were randomly assigned to three groups. Model group was left intact. Chinese medicine group received daily intragastric administration of drug extract 24 mL/kg. Drug control group was daily intragastrical y administered Puli Capsule (glucosamine hydrochloride) 24 mg/kg, once a day, until the eighth week of success model induction. An additional 24 New Zealand rabbits served as blank controls.
RESULTS AND CONCLUSION:Using quantitative PCR, matrix metal oproteinase-1, matrix metal oproteinase-3 and matrix metal oproteinase-13 expression was significantly higher in the model group than that in the other three groups. Matrix metal oproteinase-1, matrix metal oproteinase-3 and matrix metal oproteinase-13 expression was significantly lower in the Chinese medicine group and drug control group than that in the model group. These results indicated that warming the yang and benefiting the marrow for knee osteoarthritis in rabbits could effectively inhibit the expression of matrix metal oproteinase in rabbits.

Objective To understand the running status and distribution of water-improving pmjects in Anda city.Methods The running and management of the water-improving projects were investigated and located the position by Global Positioning Systerm(GPS)in Anda city.Results Among 317 water-improving projects,16.09%were either long-term projects or in poor management or had already stopped usage,77 projeets were broken,accounting for 24.29%;all inadequate supply of equipment and pipeline,83 projects had never been started,accounting for 26.18%;now,106 projects were running,accounting for 33.44%.In only 46 projects,the water fluoride concentration was lower than 1.00 mg/L,accounting for 14.51%,as a result 36 thousand people benefited.Conclusions The running status of water-improving projects was unacceptable,most of them stopped running and endemic fluorosis control was still severe in Anda city.
