Celastrol is a type of quinone methyl triterpene isolated from traditional Chinese medicine Tripterygium wilfordii, with pharmacological activities, like anti-inflammatory, immunosuppression and anti-tumor. This study focused on the effects of celastrol on adhesion, migration and invasion of lung cancer cells. The migration inhibition of lung cancer cells induced by celastrol was detected by the scratch test. The invasion inhibition of lung cancer cells induced by celastrol was measured by the transwell experiment. RT-PCR and Western blot were used to determine the effect of different concentrations of celastrol in integrin family and Akt signaling pathway in lung cancer cells. The results showed that celastrol inhibited adhesion, migration and invasion of lung cancer cells and expressions of integrins β3, β4, αv and phosphorylated Akt, GSK-3β, c-Raf, PDK1 in Akt signal pathway in a dose-dependent manner. Therefore, the study implies that Celastrol could inhibit the metastasis of lung cancer cells by suppressing Akt signaling pathway and expression of integrins.

Objective To study the chemical constituents from the roots of Euphorbia sonngarica. Methods Compounds were isolated by Sephadex LH-20,MPLC,and silica gel column chromatographies. Their structures were identified by spectral methods together with physicochemical analysis.Results Eleven compounds were isolated from the roots of E.sonngarica.They were identified as cryptomeridiol (Ⅰ),betulin(Ⅱ),betulinic acid(Ⅲ),3?-hydroxy-olean-12-en-28-oic acid(Ⅳ),7-oxo-?sitosterol (Ⅴ),erythrinasinate(Ⅵ),octaeosanoie acid(Ⅶ),1-octacosene(Ⅷ),24-methene-cycloartenol(Ⅸ),eu- phol(Ⅹ),?-sitosterol(Ⅺ).Conclusion CompoundsⅠ-Ⅷare isolated from this plant for the first time.

Seven emotions generation relates to the interaction between individual and external objective matters,which is accompanied with interaction between internal desire and external matters.The activity of seven emotions bases on essence of zang-fu organs,being regulated by five zang viscera.Heart is the upstream controller,liver is the key organ to maintain normal emotionds,spleen and stomach is the hub of emotional activities,lung is the auxiliary organ, kidney is origin of emotional generation.Five zang viscera's cooperation and interaction generate the seven emotions.

Objective To explore the value of real-time tissue elastography (RTE) with tissue dispersion quantitative analysis technique for assessment of liver fibrosis stage.Methods 51 rats were injected 6％ thioacetamide to induce liver fibrosis model,and 9 rats were injected saline as control group.In modeling 4 weeks,8 weeks,12 weeks respectively,14 rats in group of liver fibrosis model and 3 rats in control group were randomly selected to RTE.All the rats underwent tissue dispersion quantitative analysis,to obtain 12 quantitative parameters of elasticity,which included average relative strain value (MEAN),standard deviation of relative strain value (SD),area ratio of low-strain region (％ AREA),complexity (COMP),kurtosis (KURT),skewness (SKEW),contrast (CONT),entropy (ENT),inverse difference moment (IDM),angular second moment (ASM),correlation (CORR) and liver elasticity index (LF index).Subsequently,rats were sacrificed and their livers were taken for pathology analysis.Liver fibrosis model group was divided into S0,S1,S2,S3,S4 group.The 12 quantitative parameters of elasticity were compared with each group.Results 49 rats were successfully modeled,and 42 rats were analyzed.Except COMP,KURT,CORR,the other quantitative parameters had statistically differences (P ＜ 0.05).The other 9 parameters were correlated with liver fibrosis stage.Among these parameters,MEAN,％ AREA and LF index had higher related coefficient(r =-0.831,0.882,0.866).The ROC curve was made by MEAN,LF index and ％AREA to estimate the fibrosis stage,when S≥S1,S≥S2,S≥S3,S =S4,the areas under the ROCcurve were 0.884,0.925,0.934,0.962 (MEAN);0.917,0.958,0.984,0.962 (％AREA);0.917,0.948,0.966,0.967 (LF index),respectively.Conclusions As a non-invasive examination,RTE dispersion quantitative analysis technology can be used to quantitatively assess liver fibrosis.

Objective To compare clinical features,pulmonary functions,chest imaging and prognosis between combined pulmonary fibrosis and emphysema syndrome (CPFE) and idiopathic pulmonary fibrosis(IPF) without emphysematous changes in elderly patients.Methods 88 elderly IPF patients in Beijing hospital from January 2000 to October 2012 were divided into CPFE (n=30) and IPF (n =58) groups according to the CT imaging.Clinical features,blood gas analysis,pulmonary function,chest CT and survival time were compared between the two groups.Results 30 CPFE patients with the mean age of(75.5 ±7.6) years and 58 IPF patients without emphysema with the mean age of(73.7±6.8) years were enrolled.The proportions of male patients,smoking history and mortality were higher in CPFE patients than in IPF group(86.7％ vs.63.8％,28 vs.36,76.7％ vs.43.1％,x2 =5.09,9.74,8.98,P＜0.05 or 0.01).CPFE patients had a higher force vital capacity(FVC) and total lung capacity(TLC) as compared with IPF group [(2.6±0.9) L vs.(2.1± 0.5) L,(5.4±1.9) L vs.(4.4±1.1) L,t=2.69,2.35,P＜0.01 or 0.05].There were no significant differences in forced expiratory volume in one second(FEV1) and the diffusion capacity for carbon monoxide(DLCO) between the two groups.The main type of emphysema by HRCT scan were centrilobular emphysema in CPFE patients.There were lower median survival time in CPFE group than in IPF group [(3.0±0.2) years vs.(4.0±1.0) years,x2=4.50,P＜0.05].Conclusions The majority of elderly CPFE patients are males and smokers.The lung volume is increased in elderly CPFE patients as compared with IPF patients.Centrilobular emphysema is the primary type in CPFE patients.The prognosis is worse in elderly CPFE patients than in IPF patients.

METHODPharmacognostic studies were made through field collection, market investigation, document utilization, comparative morphology and histology.

RESULTThe shape and properties, microscopic characteristics in root, rhizome, leaves were worked out.

CONCLUSIONAsteropyrum can be distinguished from close relative Coptis plants by microscopic and histology characteristics. Two species in Asteropyrum can also be identified by microscopic and histology characteristics, and the morphological and histology characteristics can be used as evidences for quality control of medicinal Asteropyrum plants.

AIM: The purpose of this study is to investigate the mechanisms related to oxidized low-density lipoprotein(ox-LDL) and dendritic cells(DCs) in the process of atherosclerosis.METHODS: Human DCs were prepared from human CD14~+ peripheral blood monocytes using rhGM-CSF((100 ?g/L)) and rhIL-4(40 ?g/L).Cells were incubated with(100 mg/L) native or oxidized LDL for 72 h.The formation of foam cells was investigated by electron microscopy and oil red O staining.Phenotypic and immune functional assays were used with FACS,FITC-dextran phagocytosis,allogeneic mixed T lymphocytes reaction and secretion of Th1/Th2(IL-12/IL-2) cytokines were also conduced.RESULTS: DCs treated with ox-LDL,but not native LDL were induced into foam cells after cultured for 72 h.Compared with native LDL,ox-LDL-treated DCs were less potent in FITC-dextran phagocytosis.ox-LDL promoted allogeneic T cells proliferation.Moreover,ox-LDL upregulated CD80(72.4? 9.6 vs 89.5?10.1,P
