Japan’s Tokyo Li Ju to the hospital and Tokyo Institute of integrated clinical research, and other units recently developed jointly by urine found early colorectal cancer, which reduce colorectal cancer mortality great help. According to “Japan’s economic news” on the 20th, researchers in 250 patients with colorectal cancer study found that patients with colorectal cancer in the urine of two components acetyl spermine usually relatively high. Researchers believe that once a cell proliferation, will pass a lot of urine from diacetyl spermine, as long as patients in two urine acetyl spermine than three times higher than the normal level, can be suspected of having colorectal cancer. The patients with early colorectal cancer screening results showed that the urine test accuracy of 60%. Colorectal cancer screening is usually the first stool occult blood test, and then colorectal accurate endoscopic examination, the precision of around 60%. The researchers say that if the urine and stool screening test combination, the two inspection found no signs of cancer, do not need to carry out endoscopy, so as to reduce the burden on patients. Researchers plan to develop screening urine diacetyl spermine simple equipment, in addition to medical, could also be used to check whether colorectal cancer recurrence after surgery indications.

According to the latest a Russian “scientific information” magazine reported, the Moscow University researchers developed a new method of analysis to the early diagnosis of cancer. Reports said the new method of analysis including various biological compounds chromatography, and mass spectrometry into pieces of debris and restore three stages, can accurately identify content in the mixed solution little amino acid, sugar, fatty acids and other biological compounds. In the first phase of the study will be of the mixed solution for heating it with inert gas mixture through the column, various biological compounds has been a separate column “Separation” to open. Then the researchers used electron flow will accelerate a variety of molecule into pieces, using mass spectrometry debris measuring weight and the number of charge and determine the relationship between the structures. Finally, debris puzzles, reduced to biological molecule. Researchers Sobolevski said that the analysis of sensitivity and selectivity than the previous method 100-fold, the various components of a biological solution to discern the quality of food and drugs. They use this method to prove that the preliminary test, the measurement of amino acids in human cells can distinguish between healthy cells and cancer cells. If you use this method of cancer, the development of cancer in the early stages of cancer cells less time to make an accurate diagnosis. Reports said that after the use of biological methods to the analysis of the mixed solution, you need to identify water-soluble and non-water-soluble elements, and then use specialized reagents processed biological compounds itself and the chemical changes easier volatile, not only of increasing difficulty, and analysis the result is not very accurate.
