Endoscopic ultrasonography in the evaluation of condition and prognosis of ulcerative colitis.

Background: Ulcerative colitis (UC) is usually diagnosed through histopathology, enteroscopy, clinical symptoms, and physical findings; however, it is difficult to accurately evaluate disease severity.

Aim: To investigate the value of endoscopic ultrasonography (EUS) in the evaluation of the severity and prognosis of UC.

Methods: Patients with UC who were seen in our hospital from March 2019 to December 2020 were eligible, and disease severity was evaluated according to the modified Truelove and Witts and Mayo scores.

Paeoniflorin Prevents Intestinal Barrier Disruption and Inhibits Lipopolysaccharide (LPS)-Induced Inflammation in Caco-2 Cell Monolayers.

Inflammatory bowel disease (IBD) in humans is closely related to bacterial infection and the disruption of the intestinal barrier. Paeoniflorin (PF), a bioactive compound from Paeonia lactiflora Pallas plants, exerts a potential effect of anti-inflammatory reported in various researches. However, the effect of PF on intestinal barrier function and its related mechanisms has not been identified.

[Determination of brix and POL in sugar cane juice by using near infrared spectroscopy coupled with BP-ANN].

The models of quantitative analysis of brix and pol in sugar cane juice were established by using near infrared spectroscopy (NIR) coupled with the back propagation-artificial neural network method (BP-ANN). The spectra of cane juice samples were obtained by the way of 2 mm optical length transmission and using the NIR spectrometer of 1,000-1,800 nm wavelength. Firstly, the data of original spectra were pretreated by Savitzky-Golay derivative and mean-centering.

[Real-time monitoring of industrial acetic acid production process using a new type of online NIR analysis system].

The safe and real-time monitoring of the production process of acetic acid is always a key technical problem. The conventional online chromatographic analysis can't satisfy the requirements of real-time analysis for its inherent disadvantages. A new type of on-line near-infrared analysis system has been developed for real-time analysis of the concentration of each component in acetic acid reaction kettles instantly.
