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.

OBJECTIVETo study on the dynamic changes of Codnopsis pilosula for the guidance of the field management.

METHODUsing the random method the influences of the cultivating density and fertilizing weight at four different levels was observed.

RESULT AND CONCLUSIONThe dynamic changes of the biomass, growth period andbiological changes at different growth stages were found out. The most predominant combination of the two factors, the 1.05 million roots/hm2 of the cultivating density and 240 kg x hm(-2) of the fertilizing weight reached the highest accumulation of stems & leaves; 652 mg x d(-1) the 0.6 million roots/hm2 and 240 kg x hm(-2) reached the heaviest single fresh root. The results could be used for the cultivating, fertilizing and practicing SOP of C. pilosula.

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.

Objective:To explore a rapid and cost-effective method for identification of Candida gla-brata through the comparison of two different methods , using molecular methods of sequencing as gold standard.Methods:From our clinic, 200 strains of suspected Candida glabrata were collected during the last 3 years and selected after incubation in CHROMagar Candida medium for 48 h.By comparing the results of the CHROMagar Candida medium, the identification of the rapid trehalose test for different kinds of strains were analyzed under incubation in the tubes for 3 h, 6 h, and 24 h at 37 ℃and 42 ℃, respectively .All the strains were identified to species level by methods of sequencing .The optimal time and temperature of the trehalose test for the identification of Candida glabrata were assessed .Two different methods, CHROMagar Candida medium and the rapid trehalose test , in identification of Candi-da glabrata were compared.Results:In all the 200 strains, Candida glabrata ferment trehalose with 3 h incubation under 42 ℃ were the optimal time and temperature for fermenting trehalose .The accuracy , sensitivity, and specificity of the rapid trehalose test were 99.00% (198/200), 98.66% (147/149) and 100.00%(51/51).The accuracy rate of CHROMagar Candida medium was 79.50%(159/200), the sensitivity and specificity were only 89.93%(134/149) and 49.02%(25/51), however, compared with the domestic current popular methods , the rapid trehalose test had better time efficiency ratio .Con-clusion:The evaluation results suggest that the rapid trehalose test has advantages in terms of operational convenience and low cost , and the results can be obtained in 3 h.Therefore, it has application value in clinical laboratory .

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.
