Objective:To observe the repair effect of nano hydroxyapatite/magnesium(nHA-Mg)porous composite material modified by poly lactic acid/glycolic acid copolymer(PLGA) on the jaw bone defect of rabbits,and to elucidate the mechanisms preliminary.Methods:The mandibular defect models of 10 mm×5 mm×1 mm in the 18 rabbits were established.Nine rabbits were selected and implanted with nHA-Mg composite materials modified by PLGA in the left as experimental group and the right as blank control group;the other nine were implanted with nHA-Mg in the left as positive control group and the right as blank control group.The rabbits were sacrificed at 4, 8, 12 weeks (respectively 3 of experimental group and positive control group every time)and the mandibular defect areas were intercepted and observed by imaging and histological examination;the sizes of the newborn trabecula area and residual materials in experimental group and positive control group were compared.Results:Compared with positive control group and blank control group, the percentage of newborn trabecula area of the rabbits in experimental group was increased (P<0.05),and there was no statistic difference between positive control group and blank control group (P>0.05).The imaging results showed that the new bone formation can be observed in experimental group and better than positive control group and blank control group.The paraffin section results indicated that there were visible vascular tissue and newborn trabecula,the osteoblasts gathered around the bone trabecula;a lot of pits were located in the bone trabecula, and the pits contained osteocytes in experimental group.As the prolongation of time,thickened newborn trabecula, dense arrangement and trend of converting to lamellar bone were observed in experimental group.The hard tissue section results showed that the remaining amount of materials in experimental group was more than that in positive control group.Conclusion:nHA-Mg porous composite materials modified by PLGA can effectively reduce the rate of degradation in the body, promote osteogenesis and guide the bone regeneration.

In this study, we investigated the effect of aspirin on tumor biological effects mediated by hepatocyte growth factor/cellular-mesenchymal-epithelial transition factor (HGF/c-Met) axis, and preliminarily explored the molecular mechanism of inhibiting tumor metastasis by aspirin. The binding of aspirin to c-Met was predicted by molecular docking; cellular thermal shift assay (CETSA) was used to verify the binding of aspirin to c-Met at the cellular level. The inhibitory effect of aspirin on c-Met kinase was detected by kinase activity; Western blot, cell scattering test, cell branching morphogenesis and Transwell test were used to evaluate the cell signal transduction, morphological changes and migration and invasion ability. The results showed that aspirin could effectively inhibit the kinase activity of c-Met with a half inhibitory concentration of 0.95 mmol·L^-1. The results of docking showed that aspirin could bind to the ATP pocket of c-Met protein, and the main binding sites were Tyr1230, Tyr1159 and Met1229. The CETSA test also showed that aspirin could form binding complex with c-Met protein. Western blot results showed that aspirin could inhibit the up-regulation of phosphorylated Met stimulated by HGF in a concentration-dependent manner. The results of cell scattering test showed that aspirin could block HGF/c-Met promoted cell scattering in a concentration dependent manner. Aspirin could almost completely block the biological function mediated by c-Met activation at the concentration of 4 mmol·L^-1, and this effect was independent of HGF. Similarly, the results of MDCK cell branching morphogenesis experiment showed that aspirin could inhibit HGF/c-Met mediated invasive growth in a concentration dependent manner. The results of Transwell test showed that aspirin could block HGF/c-Met mediated cell migration and invasion in a concentration-dependent manner. Aspirin could almost completely block the biological function mediated by c-Met activation at the concentration of 4 mmol·L^-1, and this effect was independent of HGF. The above results indicate that aspirin can bind to c-Met, thereby blocking the biological effects mediated by HGF/c-Met, and inhibiting tumor metastasis. This study revealed the new biological function of aspirin, and provided a new theoretical basis for a comprehensive understanding of the anti-metastatic effect of aspirin.

Objective To investgate the application of overall hemostasis potential (OHP) experiment in the high-risk population of prethrombotic state (PTS). Methods The change of absorbance in fibrin formation and degradation was measured with a spectrophotometer at 340 nm when the plasma clotting was triggered by the low concentration of TF in the presence of urokinase. The OHP,overall coagulation potential (OCP) and the overall fibrinolysis potential (OFP) were obtained from the coagulation-fibrinolysis curve based on the computer analysis. To evaluate this OHP method,52 cancer patients,31 coronary artery disease patients,27 mid/late-stage pregnancy women and 100 healthy controls were detected. In addition,the plasma fibrinogen was detected and its correlation with OHP was studied. Results The level of OCP and OHP in PTS high-risk population was significantly higher in cancer,coronary heart disease patients and the mid/late-stage pregnancy women than in the healthy controls (P0.05). Conclusion The OHP assay may indicate the hemostatic balance; therefore,it can be used for evaluation of PTS.

OBJECTIVETo investigate the effect of four traditional Chinese medicines distributed along lung meridian, namely Ephedrae Hebra, Zingiberis Rhizoma, Scutellariae Radix and Mori Cortex, on TLR2 and NF-κB expressions in mice with lung heat syndrome, in order to study the intervention effect of the four traditional Chinese medicines (TCMs) on the lung heat syndrome.

METHODOne hundred KM mice were randomly divided into the normal control group, the model group, the Ephedrae Hebra group, the Zingiberis Rhizoma group, the Scutellariae Radix group and the Mori Cortex group (20, 10 g x kg(-1)), nasally dripped with streptococcus pneumoniae to establish the mouse lung heat syndrome model, and then administered with different TCMs. The expressions of TLR2, NF-κB p65 proteins in lung tissues were analyzed by the immunohistochemical method. The expressions of TLR2, NF-κB p65 mRNA were measured by real time PCR.

RESULTCompared with the normal control group, the expressions of TLR2 and NF-κB p65 proteins in lung tissues in the model group were higher (P < 0.01), and the expressions of TLR2 and NF-κB p65 mRNA in lung tissues were up-regulated (P < 0.01 or P < 0.05). Compared with the model group, Ephedrae Hebra high and low dose groups, the Zingiberis Rhizoma low dose group and the Scutellariae Radix high dose group showed decreased expression of TLR2 protein (P < 0.05 or P < 0.01); Ephedrae Hebra high and low dose groups, the Zingiberis Rhizoma low dose group, Scutellariae Radix high and low dose groups and Mori Cortex high and low dose groups showed reduced expression of NF-κB p65 protein (P < 0.05 or P < 0.01). Ephedrae Hebra high and low dose groups, Zingiberis Rhizoma high and low dose groups, Scutellariae Radix high dose group and Mori Cortex high dose group showed down-regulated expression of TLR2 mRNA (P < 0.01 or P < 0.05).

CONCLUSIONEphedrae Hebra, Zingiberis Rhizoma, Scutellariae Radix and Mori Cortex can induce the TLR2/NF-κB inflammatory signal pathways by down-regulating the expressions of TLR2 and NF-κB p65 in protein and mRNA, so as to alleviate the lung tissue injury in mice with lung heat syndrome.

Objective To investigate the relationship between anti mutated citrullinated vimentin (MCV) antibody, anti-cyclic citrullinated peptide (CCP) antibody with disease activity and bone erosion in patients with rheumatoid arthritis (RA), so as to provide evidence for clinical diagnosis and treatment. Methods The anti-CCP antibody and anti-MCV antibody were detected using the enzyme-linked immune adsorption method (ELISA) for 634 patients with RA. At the same time, the clinical and laboratory data were collected, and the X-ray images of hands or feet were taken. Disease activity score (DAS)28 score was calculated, and all patients were divided into high disease activity group, moderatedisease activity group, low disease activity group and stable disease group on the basis of the DAS28 score. We analyzed the relationship between the degree of anti MCV, anti CCP antibodies, and disease activity of patients by Spearman correlation. And anti CCP, anti MCV antibodies, erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) of these patients were compared at different period of bone erosion and disease activity by the Wilcoxon rank sum test and nemenyi. Results ① Positive correlation could be detected between anti-MCV antibody and ESR, CRP, number of tender joint, DAS28 score (r=0.115, P=0.004; r=0.120, P=0.003; r=0.124, P=0.002; r=0.085, P=0.032), and anti CCP antibody had no correlation with these index. The anti MCV antibodies in high disease activity group [694 (156, 1 000)] U/ml, and moderate activity group [911 (190, 1 000)] U/ml were higher than that of the low disease activity [248(150, 731)] U/ml or stable group [275(62, 928)] U/ml (U=2.29, P=0.023;U=2.25, P=0.024; U=2.45, P=0.014; U=2.4, P=0.018), and anti CCP antibody in the moderate disease activity group [499(180, 1 370)] U/ml was higher than low disease activity group [297(83, 574)] U/ml and stable group [187(67, 1 153)] U/ml (U=2.53, P=0.012; U=2.22, P=0.026). ②The anti MCV, anti CCP antibody in the bone erosion group were higher than those without bone erosion group (U=4.64, P<0.01;U=2.69, P=0.007). The anti MCV antibodies in stage Ⅱ[722(259, 1 000)] U/ml and Ⅲ group [714 (216, 1 000)] U/ml was significantly higher than that in stage Ⅰ [316(98, 1 000)] U/ml(U=3.46, P<0.01; U=4.28, P<0.01). The anti CCP antibody level in stage Ⅱ [394(180, 1 000)] U/ml and Ⅲ[391(181,1305)] U/ml was higher compared with stage Ⅰ[277 (98,898)] U/ml (U=1.99, P=0.046; U=2.92, P=0.004), and that in phase Ⅲ was higher than Ⅳ [218(71, 911)] U/ml (U=2.06, P=0.041). Conclusion Compared with anti-CCP antibody, anti-MCV antibody is closely related with disease activity, and has a better predictive value for bone erosion. Patients with higher ESR and CRP are more susceptible to bone erosion.
