Abstract

The present invention relates to the field of medical tracer diagnosis reagent. The nano carbon is an ideal trancer. Said invention relates to a nano carbon suspension injection, and is characterized by that in said injection the carbon whose grain size is 80 nm is adopted, and the polyvinyl pyrrolidone (PVP-K30) suspension adjuvant is added, then the above-mentioned materials are undergone the processes of magnetic stirring, reflux and ultrasonic treatment so as to obtain the invented nano carbon suspension injection.

Description

technical field [0001] The invention relates to the field of medical diagnostic reagents, especially the field of tracer diagnostic reagents. Background technique [0002] Cancer is the enemy of human health today, and about 6 million people in the world are killed by cancer every year. In my country, 1.6 million to 1.8 million people are diagnosed with cancer every year, and the incidence rate is second only to heart and cerebrovascular diseases. Early detection and diagnosis of cancer buys time for cancer treatment, and timely and thorough surgery to remove cancer cells is the key to successful cancer treatment. Lymph node metastasis is a common way for tumors to metastasize, such as gastric cancer, breast cancer, and cancer tumors in pancreas, lung, and colon. The long-term survival rate after surgery or radiotherapy for solid cancer is unsatisfactory. The main reason for the failure is the lymphatic metastasis of cancer cells. Therefore, it is necessary to remove the l...
