Disclosed in the present disclosure are crystal forms of a fused ring compound, and a composition thereof, a preparation method therefor and use thereof. The crystal forms comprise a crystal form I, a crystal form II, a crystal form III, a crystal form IV and a crystal form V, which have, when using X-ray diffraction, characteristic diffraction peaks at about 11.3 degrees, 17.2 degrees and 21.1 degrees, at about 25.1 degrees, 21.2 degrees and 14.1 degrees, or at about 6.6 degrees, 13.4 degrees and 8.0 degrees, at about 11.8 degrees, 13.3 degrees and 16.7 degrees, and at about 6.5 degrees, 13.3 degrees and 20.0 degrees. The crystal form I or IV is obtained by dissolving a fused ring compound in a proper solvent, followed by stirring, filtering and drying. The use of crystal form I or crystal form IV in preparation of anti-cancer drugs for inhibiting phosphatidylinositol 3-kinase. The use thereof for targeted therapy for tumors, and for anti-inflammation or treatment of autoimmune diseases.

Use of PRMT5 inhibitors such as and including (1S,2S,3S,5R)-3-((6-(difluoromethyl)-5-fluoro-1,2,3,4-tetrahydroisoquinolin-8-yl) oxy)-5-(4-methyl-7H-pyrrolo[2,3-d]pyrimidin-7-yl)cyclopentane-1,2-diol:

or a pharmaceutically acceptable salt thereof, to treat psoriasis, systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriatic arthritis and other autoimmune conditions or disorders.

The present disclosure relates to a strain of Lactobacillus sakei HEM224 (KCTC14065BP) and a composition for treating, preventing or alleviating inflammation or asthma, comprising the strain.

A strain of Lactobacillus sakei HEM224 (KCTC14065BP) according to an embodiment of the present disclosure inhibits the production of pro-inflammatory factors or inflammatory factors, and exhibits an effect of treating asthma in an asthma animal model. Therefore, the strain can be applied to pharmaceutical compositions, food compositions, health functional food compositions and feed compositions for treating, preventing or alleviating inflammation or asthma.
