Abstract: A composition includes polydatin and solvent for dissolving the polydatin, wherein the solvent comprises alcohol in a range between 40 and 95% by volume, propanediol in a range between 0 and 60% by volume, and water in remaining volume. The concentration of the polydatin must be at least 6 mg/ml. The composition has good stability in cold preservation. The composition is in a pharmaceutically acceptable administrative form selected from the group consisting of an intravenous injection, and intramuscular injection, an oral administration, a spray solution, and an aerosol form.

Abstract: The invention discloses pharmaceutical compositions containing polydatin or its pharmaceutically acceptable salts with the effect of improving microcirculation, and their application in preparing drugs which can improve microcirculation. The compositions are an non-gastrointestinal injection preparation, the preparation can be an aqueous solution which have pH 7.0-10.0 comprising 5-50% propandiol. The dosage forms of the compositions may be lyophilizing powder injection, oral form, suppository of procto-administration and other forms of administrations comprising unguent, ointment, paste film coating and the like. The compositions may be used to treat and/or prevent diseases related to microcirculation blockage. The unit form may contain 1-1000 mg polydatin or its derivatives. The invention solves the problem of using polydatin to improve microcirculation.

Abstract: This invention concerns a medical non-woven fabric containing inorganic oxides complex powder. The inorganic oxides complex powder consists of 80-95% (weight) of TiO.sub.2, 2-10% (weight) of Al.sub.2 O.sub.3 and 1-10% (weight) of SiO.sub.2. This medical non-woven fabric can improve microcirculation remarkably and has special effect of dephlogistication, detumescence and speeding up healing of wounds. Thus, it is suitable for supplementary treatment of tumefaction, surface wounds and fracture.
