Disclosed are an Inonotus Obliquus dextran, a preparation method and application thereof, and relates to the field of medicines. The dextran has a structural formula as follows: ##STR00001##
By optimizing the extraction and isolation process, the present disclosure obtains an Inonotus Obliquus dextran, which is structurally determined to be a new polysaccharide. The Inonotus Obliquus dextran prepared by the present disclosure is combined with gemcitabine hydrochloride to inhibit tumor cells with anti-tumor activity against pancreatic cancer, in addition to reduce the dosage of chemotherapeutic drugs as well as the adverse effects of chemotherapeutic drugs.

Pharmaceutical kits and use of the kits in the treatment of conditions of the eye, such as dry eye disease, which includes a first composition including a corticosteroid, an immunosuppressant or both a corticosteroid and an immunosuppressant in a pharmaceutically acceptable carrier configured for administration to a subject’s eyes; a second composition including a corticosteroid in a pharmaceutically acceptable carrier configured for administration to a subject’s eyes, where the second composition has a higher concentration of corticosteroid than the first composition; and optionally a lubricating formulation that is pharmaceutical-free. Treatment of dry eye disease includes administering topically to the eyes of a subject suffering from chronic dry eye disease the first composition over a treatment period; and if the subject suffers from an episodic flare up during the treatment period, administering the second composition to substantially alleviate the flare-up.

The invention relates to a composition, as well as a dosage, and a medicament for treatment of enveloped DNA or RNA virus induced infections and disorders, such as respiratory tract infection, and lung fibrosis. It has been found that the present composition limits the effects of virus infection on the human body, and contributes to the recovery thereof.

The present invention generally relates to treatment of iron-related conditions with iron carbohydrate complexes. One aspect of the invention is a method of treatment of iron-related conditions with a single unit dosage of at least about 0.6 grams of elemental iron via an iron carbohydrate complex. The method generally employs iron carbohydrate complexes with nearly neutral pH, physiological osmolarity, and stable and non-immunogenic carbohydrate components so as to rapidly administer high single unit doses of iron intravenously to patients in need thereof.

Disclosed is a composition for treating a joint disease or a connective tissue disease, a composition for cartilage regeneration, or a composition for treating an inflammatory disease, each of the compositions containing dextran, poloxamer or a mixture thereof. The composition stays in the joint or connective tissue for a long time due to the shock-absorbing effect, coating effect or anti-inflammation effect, relieves the shock, covers a damaged portion in a specific manner thereto, or reduces inflammation of an adhered portion. Thus, the composition may be useful for the treatment of the joint disease, the connective tissue disease, or for the cartilage regeneration.
