[Abstract]:Part one study on anti-scar effect of self-made freeze-dried gelatin-amniotic membrane in rabbit eye filtration surgery Objective: to investigate the anti-fibrosis effect of freeze-dried gelatine-amniotic membrane in rabbit eyes. Methods: Twenty-four Japanese white rabbits were randomly divided into three groups: the experimental group was treated by filtration surgery combined with freeze-dried glue and amniotic membrane transplantation group, the control group was treated with filtration surgery combined with natural amniotic membrane group, and the blank group was treated with pure filtration operation group. Clinical observation was carried out on the 7th day, 14th day, 21st day and 30th day after operation respectively. The histopathological observation was performed by immunohistochemical staining with HE staining massion staining and a-SMA staining. The expression of connective tissue growth factor (CTGF) mRNA in its filtered region was measured by real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR). Results: the conjunctival hyperemia and intraocular pressure were observed 7 days, 14 days and 21 days and 30 days after operation respectively. In the group of filtration surgery and freeze-dried glue combined with amniotic membrane transplantation, the wound healed well, the scar formation was effectively reduced, and the long-term effect was ensured. Quantitative reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect the expression level of connective tissue growth factor (CTGF) mRNA in the filtered region. The expression of CTGF mRNA in each group reached its peak on the 14th day after operation. The expression of CTGFmRNA in each time period of the experiment was as follows: the control group was blank group. Conclusion: in our experiment, freeze-dried amniotic membrane prolonged the survival time of filtering bleb, reduced the degree of conjunctival hyperemia, inhibited tissue fibrosis, and reduced intraocular pressure to some extent after operation. This new material may be routinely used in glaucoma filtration surgery. The second part: study on anti-scar effect of self-made freeze-dried gelatin-amniotic membrane sustained release drug membrane in rabbit eye filtration surgery Objective: to study the application of freeze-dried gel combined with amniotic membrane as sustained-release drug membrane under conjunctival flap of rabbit eye filtration, which can prevent fibrosis, prolong survival time of filtering bleb, reduce intraocular pressure (IOP), and promote wound healing after filtering operation. Methods: Twenty-four Japanese white rabbits were randomly divided into three groups: the experimental group was treated with filtration surgery and conjunctival flap placed 5-fu gel and freeze-dried amniotic membrane, the control group was treated with 5-fu under the conjunctival flap, and the control group was treated with filtration only. Clinical observation was carried out on the 7th day, 14th day, 21st day and 30th day after operation respectively. The histopathological observation was performed by immunohistochemical staining with HE staining massion staining and a-SMA staining. High performance liquid chromatography (HPLC) was used to detect the pharmacokinetics of 5-Fu sustained-release drug release system in rabbit eyes. Results: the conjunctival hyperemia and intraocular pressure were observed 7 days, 14 days and 21 days and 30 days after operation respectively. Filtration surgery combined with freeze-dried glue and amniotic membrane sustained release drug membrane transplantation group had good wound healing and effectively reduced scar formation. It was helpful to ensure the long-term effect. The 5-Fu release amount in experimental group was higher than that in group B on the 3rd day after operation. 5-FU was released slowly from the sustained release system, and the drug release in vivo and in vitro was stable, high efficiency and no sudden release. Conclusion: in our experiment, freeze-dried gel combined with amniotic membrane prolonged the survival time of filtration bleb, inhibited the degree of scar formation in subconjunctival tissue, and maintained the postoperative efficacy for a long time. This new material may be used in subsequent glaucoma filtration surgery.
