RNA interference is provided for inhibition of connective tissue growth factor mRNA expression in ocular disorders involving CTGF expression. Ocular disorders involving aberrant CTGF expression include glaucoma, macular degeneration, diabetic retinopathy, choroidal neovascularization, proliferative vitreoretinopathy and wound healing. Such disorders are treated by administering interfering RNAs of the present invention.

The invention provides application of lncRNA-MALAT1 in preparing a proliferative vitroretinopathy (PVR) diagnosis reagent. The invention also provides an MALAT1 detection kit for PVR diagnosis. The kit comprises an RNA (ribonucleic acid) extraction system, a reverse transcription reaction system and a PCR (polymerase chain reaction) reaction system. On the basis of real-time fluorescent quantitative PCR, the kit can be used for carrying out PVR early diagnosis by detecting the relative content of MALAT1 in the serum or plasma. The method has the characteristics of small trauma and the like, and is convenient to operate.

The invention relates to an ophthalmic controlled release system of long-action low molecular heparin which comprises the low molecular heparin as drug and a drug carrier made from synthesized or natural biodegradable high molecular materials and is characterized in that the proportion range of the low molecular heparin and the drug carrier is (1:8) to (5:1); the average molecular mass of the lowmolecular heparin is less than 8000 Dalton; the molecules less than 8000 Dalton, the salt compounds of the low molecular heparin such as sodium salt, calcium salt and kali salt included, take up not less than 60 percent of the total molecules of the low molecular heparin; the synthesized or natural biodegradable high molecular materials are polyglycolic acid and gelatin or bletilia striata gelatinrespectively. The ophthalmic controlled release system of long-action low molecular heparin can effectively inhibit the proliferation and migration of lenticular epithelia and fibroblasts in eyes, reduce fibrinous exudates post operation, alleviate inflammatory reaction post operation and prevent posterior capsular opacification, thereby inhibiting the occurrence of after-cataract; meanwhile, theophthalmic controlled release system of long-action low molecular heparin inhibits the proliferation of retinal pigment epithelium and fibroblasts, thus inhibiting the proliferative vitreoretinopathy(PVR).
