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.

Heptamethine cyanines for use as fluorescent markers of the biliary and renal systems are disclosed. Certain heptamethine cyanines exhibit renal system specificity, while others exhibit biliary system specificity. The compounds may be used for diagnostic purposes and/or for visualization of renal or biliary systems during surgery.

Indirect chromoendoscopy is performed by providing a subject with an orally administered composition which includes indigo carmine dye mixed with polyethylene glycol (PEG). Preferably, the subject ingests at least 160 mg of indigo carmine prior to the endoscopic procedure. This is accomplished by ingesting 1 ml to 6 L of a premixed or reconstituted indigo carmine and PEG composition up to twenty four hours prior to the endoscopic procedure.

A technique for preparing a nanoplatform-based tumor-targeted diagnostic contrast agent which enables precise local diagnosis of cancer lesions is provided. The nanoplatform-based tumor-targeted diagnostic contrast agent can avoid the situation in which normal tissue is unnecessarily excised or tumor tissue is not excised when tumor removal surgery is performed under fluorescence image guidance, and can be visualized by emitting light under near-infrared ray induction as the contrast agent is directly applied to the local area and then quickly and accurately penetrates/is absorbed into the cancer lesion so that a clinical surgeon efficiently and conveniently performs surgery in an operating room during laparoscopic surgery with minimal incision or open surgery according to the occurrence site and progression of cancer.

The tumor stroma, which accounts for a large part of the tumor mass, represents an attractive target for the delivery of diagnostic and therapeutic compounds. Here, the focus is notably on a subpopulation of stromal cells, known as cancer-associated fibroblasts, which are present in more than 90% of epithelial carcinomas, including pancreatic, colon, and breast cancer. Cancer-associated fibroblasts feature high expression of FAP, which is not detectable in adult normal tissue but is associated with a poor prognosis in cancer patients. The present invention provides small-molecule radiopharmaceutical and imaging agents based on a FAP-specific inhibitor.

The present invention relates to the field of medicine, specifically to ophthalmic surgery, more specifically to a novel ophthalmic dye for surgery which does not stain living cells.

The invention relates to a tantalum nanocomposite and a preparation method and application thereof, lymph tracer and radiosensitizer. The tantalum nanocomposite provided in the invention includes tantalum nanoparticle and bio-surfactant acting on the tantalum nanoparticle. The tantalum nanocomposite provided in the invention has good biosafety and can improve the effect of radiation therapy as a radiosensitizer.

Heptamethine cyanine fluorophore conjugates and conjugate precursors are disclosed. Methods of using the conjugates and conjugate precursors are also disclosed. The disclosed conjugates are neutral zwitterionic molecules and exhibit little or no aggregation.

The present disclosure encompasses methods and compositions for staining ocular structures in ophthalmologic procedures. The compositions generally include a mydriatic compound and a dye. The compositions may additionally include a pain-relieving compound and a second mydriatic compound. Also provided herein is a method of delivering a pharmaceutical composition, which includes administering to an eye of a subject an ophthalmic pharmaceutical composition of the present disclosure.

A composition containing Brilliant Blue G (BBG) or a pharmaceutically acceptable salt thereof, and a positional isomer of Brilliant Blue G (BBG) or a pharmaceutically acceptable salt thereof, the composition containing 90 wt % or more and 100 wt % or less of one or both of Brilliant Blue G (BBG) and the pharmaceutically acceptable salt thereof in the total of the Brilliant Blue G (BBG), the pharmaceutically acceptable salt of Brilliant Blue G (BBG), the positional isomer of Brilliant Blue G (BBG), and the pharmaceutically acceptable salt of the positional isomer of Brilliant Blue G (BBG), a method for producing said composition, and a method of removing the ocular membrane of a human patient.
