Bibenzyl is a type of active compounds abundant in Dendrobium. In the present study, we investigated the inhibitory effects of six bibenzyls isolated from Dendrobium species on vascular endothelial growth factor (VEGF)-induced tube formation in human umbilical vascular endothelial cells (HUVECs). All those bibenzyls inhibited VEGF-induced tube formation at 10 micromol x L(-1) except tristin, and of which moscatilin was found to have the strongest activity at the same concentration. The lowest effective concentration of moscatilin was 1 micromol x L(-1). Further results showed that moscatilin inhibited VEGF-induced capillary-like tube formation on HUVECs in a concentration-dependent manner. Western blotting results showed that moscatilin also inhibited VEGF-induced phosphorylation of VEGFR2 (Flk-1/KDR) and extracellular signal-regulated kinase 1/2 (ERK1/2). Further results showed that moscatilin inhibited VEGF-induced activation of c-Raf and MEK1/2, which are both upstream signals of ERK1/2. Taken together, results presented here demonstrated that moscatilin inhibited angiogenesis via blocking the activation of VEGFR2 (Flk-1/KDR) and c-Raf-MEK1/2-ERK1/2 signals.

Objective:To study the effectiveness of inferior pole fracture of patella treating by the new tension band.Methods:From Dec.2011 to Dec.2013, 21 patients with inferior pole fracture of patella were treated with the new tension band which consisted of cannulated screw, titanium cable and shims. There were 21 patients[10 males, 11 females, the average age was 54 years(21 to 79)],of whom,all were“fell on knees”.Results:The average operation time was 89 min (57-197 min),the follow-up visits were done from 7-31 months ( average 18 months) , the bone healing time was from 8-12 weeks (average 10.5 weeks).The post operation assessment was done by Bostman score, from 20 -30 (average 27),10 excellent,and 11 good.No complication occurred.Conclusion:The new tension band is the effective treatment for inferior pole fracture of patella.The internal fixation is reliable, it is simple to operate, and patients can take exercises as early as possible.Therefore, the new tension band has a bet-ter clinical value.

ABSTRACT:OBJECTIVE In metabonomics method based on liquid mass combination of dampness stagnancy due to spleen deficiency model and normal control group rats urine,To explore the differences metabolites in the urine of the model rats. METHODS The model of spleen deficiency and dampness stagnancy in rats was induced with high-fat and low-protein diet plus exhaustive swimming methods.Using high performance liquid chromatography(HPLC)-quadrupole-time of flight tandem mass spectrometer technique to detect the small molecule metabolites in urine samples in the 2 groups,Metabolic fingerprint as prin-cipal component analysis and partial least squares discriminant analysis,find out the differences of characteristics of metabo-lites.RESULTS Compared with the control group,the urine of rats in model group identified 6 different metabolites,respec-tively:alpha keto glutarate,citrulline,lactic acid,glutamine,citric acid,serotonin.CONCLUSION Dampness stagnancy due to spleen deficiency model rats body sugar and protein metabolism in disorder,energy supply,gastrointestinal function drops, antioxidant ability,its mechanism may be related to the change of the small molecule metabolites.

OBJECTIVETo investigate the relationship between Arg778Leu/Gln gene mutation spot in ATP7B and TCM Syndrome type in Chinese patients with Wilson disease (WD).

METHODSExon 8 of ATP7B of 90 WD patients and 30 healthy controls were amplified by PCR and analysed by restriction enzyme Msp I, the TCM Syndrome type of the patients was differentiated at the same time.

RESULTSIn the 90 WD patients, 34 with Arg778Leu/Gln of exon 8 were detected, among them 20 cases belonged to the TCM Syndrome type of endogenous Liver-Wind agitation.

CONCLUSIONOnset age of WD patients with Arg778Leu/Gln mutation is later than that without this mutation. Arg778Leu/Gln mutation might be related to the TCM Syndrome type of endogenous Liver-Wind agitation.

Objective To construct targeted ultrasound contrast agent carried goat anti-mouse IgG antibody (UCA-IgG) and evaluate the effectiveness of its targeted adhesion using parallel plate flow chamber. Methods The ultrasound contrast agent targeted to mouse IgG was designed by conjugating monoclonal antibodies against mouse lgG to the lipid monolayer shell of the agent using biotin-streptavidin. The binding of IgG antibodies to the ultrasound contrast agent were identified by fluorescence in vitro. The attachment and detachment of UCA-IgG to mouse IgG immobilized on a culture dish were assessed in a parallel-plate flow chamber. While the plate lacked mouse IgG,or blocked with large number of goat anti-mouse IgG were served as two control groups. Results UCA-IgG issued a bright green fluorescence, while the contral lipid ultrasound contrast agent didn't show fluorescence. The number of UCA-IgG bound to mouse IgG of experimental group was greater than two control groups,increased with increasing coverslips surface antibody concentrations (P<0. 05),and there was significant positive correlation between the number of UCA-IgG bound to mouse IgG and time of combination (P<0.05). The adhesion rate of experimental group increased with shear stress before 0. 5×10-5 N/cm2 (P<0.05) and then decreased (P<0. 05). There was limited adherence of control groups to the UCA-IgG. The stess of half-maximal detachment was increased with increasing coverslips surface antibody concentrations (P<0.05). Conclusions UCA-IgG could adhere to mouse IgG in the physical conditions. It may provide strong supports for studying other targeted ultrasound contrast agent preliminary and fatherly in vitro.
