Objective: The scavenging capacity of free radicals by enzymes-hydrolyzed wheat bran (EHWB) and its protection against DNA damage were studied in vitro. Method: EHWB, prepared by hydrolyzing de-starched wheat bran using enzymes from Aspergillus niger fermentation, was used to test its scavenging capacity of free radicals and protection against DNA damage caused by hydroxyl free radical in vitro. Results: The capacity of scavenging free radicals by EHWB was shown, and EHWB could protect DNA damage caused by hydroxyl radicals. Conclusion: EHWB has higher free radicals scavenging capacity.

Objective To study the effects of butylphthalide on homocysteine (Hcy) and C-reactive protein (CRP) levels in patients with acute cerebral infarction.Methods One hundred and ten patients with acute cerebral infarction were divided into control group and treatment group by random digits table,with 55 patients in each group.Two groups were given conventional treatment for 3 weeks,and treatment group was added butylphthalide 200 mg oral application,thrice a day.Two groups were compared in the total effective rate,neurological deficit scores (NDS) and serum Hcy and CRP levels.Results The total effective rate in treatment group was significantly higher than that in control group [ 89.09% (49/55) vs.61.82% (34/55),x2 =11.044,P< 0.01 ].The NDS in two groups after treatment were significantly decreased than those before treatment [treatment group:( 11.24 ± 3.19) scores vs.(23.19 ± 4.06) scores,control group:( 18.56 ± 4.03 )scores vs. (22.31 ± 4.17) scores,P < 0.01 ],and NDS in treatment group after treatment was significantly lower than that in control group (P< 0.01 ).The serum Hcy and CRP levels in two groups after treatment were significantly lower than those before treatment [ treatment group:( 13.12 ± 3.58 ) μ mol/L vs.(27.36 ± 6.84 )μ mol/L,( 10.33 ± 3.10) mg/L vs.( 18.96 ± 5.38) mg/L;control group:( 16.41 ± 4.76) μ mol/L vs.(28.73 ±6.32) μ mol/L,(13.16±4.02) mg/L vs. (19.17 ± 5.74) mg/L,P < 0.01 ],serum Hcy and CRP levels in treatment group after treatment were significantly lower than those in control group (P < 0.01 ).Conclusion Butylphthalide can reduce serum Hcy and CRP levels,reduce inflammation and improve the condition of patients with acute cerebral infarction.

As an emerging tumor marker, the rarity and heterogeneity of circulating tumor cells (CTCs) increase the difficulty of detection. In recent years, CTCs enrichment technology based on biophysical, biochemical and microfluidic properties has been continuously developed, which has promoted the research and application of CTCs in malignant tumors diagnosis, clinical treatment and prognosis evaluation. Although there are still some deficiencies in the detection of CTCs, with the interdisciplinary integration, CTCs will play increasingly important roles in the diagnosis and treatment of malignant tumors.

Objective To explore the influence of salinomycin in the growth, apoptosis and invasion of human bladder cancer 5637 cells,and to clarify its possible mechanism.Methods The human bladder cancer 5637 cells cultured invitro at logarithmic growth phase were divided into control group and different doses of salinomycin(15, 30 and 60μmol·L-1 )groups.The inhibitory rate of the growth of 5637 cells in various groups was measured by MTT assay. Flow cytometry was used to detect the apoptotic rates of 5637 cells in various groups. The invasiveness of 5637 cells was tested by Matrigel Invasion Assay.The expression levels ofβ-catenin protein in 5637 cells in various groups were determined by Western blotting method. Results Compared with control group,the inhibitory rates of growth of human bladder cancer 5637 cells in different doses of salinomycin groups were increased significantly(P<0.05);the apoptotic rates were increased(P<0.05).the number of cells passed the Matrigel was decreased(P<0.05),and the expression level ofβ-catenin protein was decreased (P<0.05).Compared with low dose of salinomycin group,the inhibitory rate of growth of 5637 cells in high dose of salinomycin group was increased(P<0.05);the apoptotic rate was increased(P<0.05),the number of cells passed the Matrigel was decreased (P < 0.05 ), and the expression levels of β-catenin protein was decreased (P<0.05). Conclusion Salinomycin can inhibit the growth of 5637 cells significantly,increase the apoptosis,and decrease the cell invasion;the inhibitory effect may act by inhibiting the Wnt/β-catenin pathway.

AIM:To investigate the effect of ?-cyclodextrin inclusion on transdermal absorption of volatile oil in lilac-cassiabark Gel. METHODS: The release test of two kinds of lilac-cassiabark Gel(gel A without ?-cyclodextrin inclusion and gel B with ?-cyclodextrin inclusion) was assayed with Franz diffusion cell with the help of the cumulative amount of eugenol in unit area in vitro. RESULTS: The percutaneous absorption process of eugenol in two kinds of gels were conformed to zero-order releasing model,and the transdermal rates were 16.212?4.128 and 11.344?1.929 ?g/(cm~2?h) respectively.Compared with gel A,the transdermal rate of eugenol was slower in gel B(P
