A process for inhibiting vascular proliferation separately introduces components into the eye to generate plasmin in the eye in amounts to induce complete posterior vitreous detachment where the vitreoretinal interface is devoid of cortical vitreous remnants. The process administers a combination of lysine-plasminogen, at least one recombinant plasminogen activator selected from the group consisting of urokinase, streptokinase, tissue plasminogen activator, chondroitinase, pro-urokinase, retavase, metaloproteinase, and thermolysin and a gaseous adjuvant to form a cavity in the vitreous. The composition is introduced into the vitreous in an amount effective to induce crosslinking of the vitreous and to induce substantially complete posterior vitreous detachment from the retina without causing inflammation of the retina. The gaseous adjuvant material is introduced into the vitreous simultaneously with or after the lysine-plasminogen and recombinant plasminogen activator such as recombinant urokinase to compress the vitreous against the retina while the composition induces the complete posterior vitreous detachment.

The invention relates to use of microbubbles with high-intensity cavitation generated by combining ultrasonic in preparation of anti-tumor neovascularization medicaments. The microbubbles are high-intensity cavitation effect microbubbles generating mechanical damage under the action of pulse-type high-peak negative pressure ultrasonic energy; and the ultrasonic energy has higher peak sound pressure and lower transmitting duty cycle. The generated high-intensity cavitation effect can generate obvious tumor microcirculation blocking effect on the tumor neovascularization, repeatedly perform deprivation therapy for further generating tumor growth inhibition, and reduce the transfer rate of malignant tumors. The novel treatment use of the microbubbles is applied to the treatment of various solid malignant tumors and angiogenesis pathological changes and is brand new use of the microbubble with application prospect.

The invention discloses a medicament for treating neovascularization diseases. The medicament employs miRNA-132 and miRNA-155 as targets and two specific antagomirs, antagomir-132 and antagomir-155, as the basic components. The above two micronucleus acids are knocked down in a lesion at the same time, so as to inhibit excessive proliferation of new vessels to achieve therapeutic effect. To ensure the effective application of the drug, the invention adopts in vivo delivery vectors, such as a histidine-lysine polypeptide polymer HKP and a ligand targeted delivery nanoparticle system RGD-PEG-HKP, in order to improve the specificity and efficiency of medicament delivered into angiogenesis sites (eye or tumor).
