Abstract: The use of a mitoxantrone preparation in the preparation of a drug for diagnosing and treating breast cancer. Provided is the use of mitoxantrone and/or a pharmaceutically acceptable salt thereof in the preparation of a lymphatic tracer in a disease associated with breast resection. No local or systemic toxic and side effects are seen after local injection of the preparation, suggesting that the preparation has good tolerance, effectiveness and safety, which provides a new treatment idea for thoroughly curing breast cancer in a breast cancer patient.

Abstract: A method for producing hot water and a device especially for carrying out the method are provided. The method utilizes combined heat resources of solar energy and heat pump in the manner of heating water at multiple stages and accumulating energy. The device comprises solar energy collector, heat pump, electrical heater, water tank, and control unit. The device also includes water-heating tanks with multiple stages. A heating means with multiple stages at different temperatures is formed either by the solar energy collector or by the collector and the heat pump. The outputting end of the two or more heating stages constituted by the solar energy collector or by the collector and the heat pump is connected through ducts to the corresponding water-heating tanks. A predetermined amount of produced water heated at multiple stages is respectively stored in the water-heating tanks.

Abstract: The present invention discloses a variable temperature air-conditioning method using underground reservoir and water-source heat pump with energy-storage and its specialized equipment, which includes a geothermal heat exchanging cycling loop and an air-conditioning heat exchanging cycling loop, wherein the air-conditioning heat exchanging cycling loop includes a variable temperature air-conditioning heat exchanging cycling loop. In the geothermal heat exchanging cycling loop, the water-source heat pump exchanges energy with energy-storage tanks, and in the air-conditioning heat exchanging cycling loop, the energy-storage tanks exchanges energy with an air-conditioning load loop.
