The invention provides a composition for eyes and having improved drying protection and retention, and belongs to the field of pharmaceutical preparations. The composition includes cyclosporin, nano micelle in-situ gel, and hyaluronic acid or a pharmaceutically acceptable salt thereof; and the composition is in a liquid form at normal temperature or low temperature, is a hydrosol form when the temperature is more than 35 DEG C, and can still maintain complete under the shear stress caused by the eyelid blinking of patients. A preparation method includes providing first solute and second solute; and mixing the solute under a condition of taking water as a substrate so that the composition including gel dispersoid can be formed. The provided composition is high in bioavailability and small in effect on eye pain and irritation, cannot cause the blurring of vision, can improve the compliance of the patients and/or reduce side-effects, can enhance ocular surface health, and has antibacterial and antiseptic effects; and the preparation method can increase adhesiveness, enhance gelation temperature, prolong retention and effective acting time, rising encapsulation yield, avoid self-agglomeration phenomenon, and enhance antioxidant protection effects and stability performance.

The invention discloses a drug for treating arrhythmia. A nardostachys chinensis batal medicinal material is extracted firstly by using ethanol to obtain a nardostachys chinensis batal ethanol extract, and then, the nardostachys chinensis batal ethanol extract is prepared into the required dosage form. The ethanol extraction method comprises the following steps of: (1) crushing the nardostachys chinensis batal medicinal material, then, adding over 95% of ethanol with the concentration of 8-12 times, soaking at room temperature for 12-24h, filtering and collecting filtrate; (2) coldly soaking and extracting the filtrate twice according to the method in step (1), and respectively collecting filtrates; and (3) mixing all the filtrates, and then carrying out vacuum concentration. The drug has a remarkable curative effect for the pathogenesis of arrhythmia and particularly for atrial arrhythmia, atrial premature beat, atrial tachycardia, atria flutter, atrial fibrillation and the like and is little in toxic or side effect and good in patient compliance.
