What Is the Submucosa?
The diffuse reflectance spectral characteristics of human normal bladder and superficial bladder cancers in the submucosa of 300 ~ 900 nm and their differences were studied. The spectrophotometer with an integrating sphere accessory was used to obtain the diffuse reflectance spectrum of the tissue. The results show that at 300-900 nm, the diffuse reflectance of normal bladder mucosa / submucosa to any wavelength is significantly larger than that of cancerous mucosa / submucosa to corresponding wavelengths.

- The diffuse reflectance spectral characteristics of human normal bladder and superficial bladder cancers in the submucosa of 300 ~ 900 nm and their differences were studied. The spectrophotometer with an integrating sphere accessory was used to obtain the diffuse reflectance spectrum of the tissue. The results show that at 300-900 nm, the diffuse reflectance of normal bladder mucosa / submucosa to any wavelength is significantly larger than that of cancerous mucosa / submucosa to corresponding wavelengths.
- The peaks of the diffuse reflectance spectrum of the normal mucosa / submucosa of the bladder are 370 nm, 520 nm, 550 nm, and 660 nm, and their peaks are 52.4%, 60.7%, 56.1%, and 75.5%. The peaks of diffuse reflection spectra of cancerous mucosa / submucosa were 320 nm, 520 nm, 550 nm, and 660 nm, and their peaks were 43.7%, 33.4%, 30.6%, and 70.2%, respectively. The diffuse reflectance spectrum of the normal mucosa / submucosa of the bladder has a peak at 370 nm, while the diffuse reflectance spectrum of the cancerous mucosa / submucosa has no peak at 370 nm and a peak at 320 nm. The diffuse reflectance spectrum of the normal mucosa / submucosa of the bladder has no peak at 320 nm. The mucosal / submucosal lesions of the bladder caused the peaks of the diffuse reflectance spectra of the tissue at 520 nm, 550 nm, and 660 nm to decrease by 45.0%, 45.5%, and 7.02%, respectively. This shows that the bladder's mucosal / submucosal lesions have significantly changed the composition and structure of tissues, especially the content of oxyhemoglobin and deoxyhemoglobin in the tissue.
