Objective To research the best plant treatment formulation of flos carthami,aloe vera and potato on mannitol-induced phlebitis in rabbits. Methods Using mannitol-induced phlebitis model in rabbits,the experimental groups contained simple dosage and mixture of three plants,the control groups were blank control group and 95% ethanol group.The curative effects of phlebitis treatment were observed between groups. Results The curative effect of aloe vera and potato mixture group was the best compared with other groups. Conclusions All of the three plants have good curative effects on mannitol-induced phlebitis,and the best plant treatment formulation was aloevera and potato mix-using.

Objective To explore the mechanism of hepatitis B virus X protein down-regulating DKK4 and its effect on the proliferation, migration of HCC cell lines. Methods HCC cell lines HepG2 and SMMC7721 cells were infected with adenovirus encoding hepatitis B virus X protein (Ad-HBx), and GFP adenovirus (Ad-GFP) was designed as a control group. We used deacetylase inhibitor (TSA) to treat HCC cell lines and transfected HCC cell lines with small interfering RNA-histone deacetylase 1 (si-HDAC1) and lentivirus overexpressing DKK4. Western blot was used to detect the expression of DKK4, HDAC1 and SIRT1. The proliferation and migration ability of HCC lines were assessed using MTT, crystal violet experiment and Transwell experiment. Results DKK4 expression level was significantly downregulated after Ad-HBx infection (

Objective To investigate the value of F-actin autoantibodies in the serum of patients with systemic lupus erythematosus (SLE),and to explore the relationships between F-actin autoantibodies and other clinical indicators.Methods ELISA was established to detect serum levels of F-actin autoantibodies in 93 inpatients with SLE from March 2017 to January 2018 (case group,n=93),72 patients with rheumatoid arthritis (RA) (disease control group) and 83 healthy subjects (healthy control group) were included during the same period.The positive rates of F-actin autoantibodies between the case group and the two control group were compared.Clinical data including SLE disease activity index (SLEDAI),immuno-globulin (lg)G,erythrocyte sedimentation rate (ESR),anti-dsDNA,and antinuclear antibody (ANA) of 93 patients with SLE were collected and the correlation analysis between F-actin autoantibodies units was applied respectively.The diagnostic performance of F-actin autoantibodies in SLE was analyzed by using the receiver operating characteristic curve (ROC).T test,Chi-square test and Spearman/Pearson correlation analysis were applied for statistical analysis.Results The serum levels of F-actin autoantibodies in the SLE case group,disease control group,and healthy control group were (18±13),(12±6),and (11±5) U,respectively,the differences between SLE case group and disease control group,and healthy control group were significant (t=3.163,P=0.001 9;t=4.436,P<0.01).The positive rates of F-actin autoantibodies were 33%(31/93) in patients with SLE,10%(7/72) in disease control group,and 4%(3/83) in healthy control group.The F-actin autoanti-bodies units in SLE were correlated with SLEDAI,IgG,ESR,anti-dsDNA,and ANA (r=0.273 7,P=0.008 3;r=0.558 7,P<0.01;r=0.419 9,P=0.000 1,r=0.351 4,P=0.001 1,r=0.460 9,P<0.01),in which F-actin autoantibodies units showed significant correlation with IgG and ANA.In the ROC curve,the area under the curve(AUC) was 0.62 [95%CI(0.54,0.70)],P=0.001 3.which was statistically significant.When the cut-off value of the F-actin autoantibodies was 14.04 U,the Youden's index (YI) was the largest (YI=0.30),and the sen-sitivity for the diagnosis of SLE was 0.77,the specificity was 0.53.Conclusion The positive rate of F-actin autoantibodies in the serum of patients with SLE is higher than that of RA and healthy controls,so it has certain diagnostic value for SLE.The F-actin autoantibodies units is correlated with both SLEDAI,ESR,and anti-dsDNA,suggesting that F-actin autoantibodies units may be a new biomarker for disease activity assessment of SLE patients.
