Objective To study the effect of hyaluronidase and VEGF on human breast cancer invasion and metastasis. Methods By means of ELSA and immunohistochemistry, hyaluronidase and VEGF were detected in breast cancer. Results Hyaluronidase were (3.99?1.91) mU/g, (8.01?2.59) mU/g and (12.00?3.96) mU/g in gradeⅠ, Ⅱ, Ⅲ of breast cancer respectively. Hyaluronidase levels were significantly elevated in grade Ⅱ,Ⅲ as compared to grade Ⅰ, Hyaluronidase levels were significantly elevated in grade Ⅲ as compared to grade Ⅱ(P

Pharmacokinetic analysis has attracted more and more attentions in the research field of bioactive natural product. However, there is limited study on the pharmacokinetics of polysaccharides. This paper focused on the research progresses of pharmacokinetics of polysaccharide, summarized the applications of chromatography, isotope labeling method, spectrophotometry, fluorospectrophotometry and biological assay in the analysis of polysaccharide pharmacokinetics, elucidated the behaviors of absorption, distribution, degradation and excretion of polysaccharide in experimental animals, and revealed the effects of physicochemical characteristic, administration dose and route on the pharmacokinetic properties of polysaccharide, which could be served as a reference for the related works.

Objective To analyze the effect of Fufang Xueshuantong capsule on glaucomatous optic atrophy and its influence on ocular hemodynamics.Methods 124 cases of patients with glaucomatous optic atrophy from April 2014 to December 2016 in our hospital were selected,and randomly divided into experimental group and control group according to the order of hospital admission , with 62 cases in each group.The control group was treated with nerve growth factor plus vitamin needling,the experimental group was treated with nerve growth factor and vitamin and compound Xueshuantong capsule.Observation and comparison the total effective rate, visual function (visual acuity, total gray value) improvement of the two groups of patients, as well as the changes of ocular hemodynamic parameters (systolic peak velocity, diastolic End-stage blood flow velocity, resistance index, pulsatility index).Results The total effective rate of the experimental group was 93.55%(58/62), the total effective rate of the control group was 70.97%(44/62), the total effective rate of the experimental group was higher than the control group (P <0.05)).After treatment, the visual acuity of the experimental group was significantly higher than the control group, the total gray value of the experimental group was significantly lower than the control group (P<0.05).The peak systolic velocity and end diastolic velocity in the experimental group were significantly higher than those in the control group (P<0.05).The resistance index and pulsatility index in the experimental group were lower than those in the control group (P<0.05). Conclusion Compound Xueshuantong capsule is effective in the treatment of glaucomatous optic atrophy , can improve the ocular hemodynamics and improve the visual function.

AIM: To observe the effect of diammonii glycyrrhizinatis (DG) on collagen synthesis induced by angioplasty in rabbits. METHODS: The right common carotid artery of male rabbits were injured with 3.5F balloon catheter. Four weeks after operation, arterial tissure collagen content, serum procollagen type I(PCI), procollagen type Ⅲ(PCⅢ) concentration, neointimal thickness and the rate of stenosis were measured.RESULTS: Arterial tissue collagen content, serum PCI, PCⅢ concentration, neointimal thickness and the rate of stenosis of low and high dose DG group is lower than those of injured group.CONCLUSION: DG could inhibit collagen synthesis and neointimal proliferation of rabbits carotid artery induced by angioplasty. It suggests that DG might have clinical potential prespective in prevention and therapy of restenosis.
