Results were shown as followings:(1) Sodium selenite at 0～2.5 μmol/L significantly increased the antioxidative capacity of L-02 cells without having remarkable impact on SMMC-7721 cells;(2) Sodium selenite at concentrations above significantly increased telomerase activity, hTERT gene expression and telomere length of L-02 cells without significant impact on SMMC-7721 cells;(3) Sodium selenite at higher concentrations (larger than 5 μmol/L) resulted in peroxidation of L-02 cells, while scutellarin significantly counteracted its effect;(4) Selenium-rich amino acids from silkworm pupas in the range of 0.5～2.5 μmol/L Se significantly inhibited SMMC-7721 cell growth, induced apoptosis and cell cycle change, and the generation of reactive oxygen species. In contrast, sodium selenite and selenomethionine only had weak impact on them at the same concentrations;(5) A new selenium-containing protein was found from selenium-rich silkworm pupas, which is worthy to be study further;(6) An expression vector containing ansense RNA of hTERT gene were constructed and used to transfect SMMC-7721 cells. They were observed to inhibit hepatoma cells.

Purpose: To investigate the influence of retinal photocoagulation with an indirect ophthalmoscopy contact lens on corneal endothelial cells.Methods: Seventeen eyes of 17 patients were evaluated, and corneal endothelial cells were measured twice: just before retinal photocoagulation using an indirect ophthalmoscopy contact lens and 33.2 ± 10.2 days after surgery.

HA increased level of NO by activating NOS after combining with H〓 and H〓 receptors; and on the one hand 5-HT caused brain microvessel endothelial cells constracting strongly, made the tight joint opening, increased the permeability of BBB, and on the other hand 5-HT increased the quantity of pinocytosis vesicle in endothelial cells and enhance the permeability of BBB after comining with 5-HT〓 receptor.

HA与H〓和H〓受体结合，激活NO合成酶，使NO含量增多而诱发BBB通透性增加；5-HT与5-HT〓受体结合，一方面引起脑微血管内皮细胞强烈收缩，使内皮细胞间的紧密连接开放，BBB通透性增高，另一方面可引起内皮细胞转运小泡增加，BBB通透性增高。
