Value of Improved Mayo Endoscopic Score for evaluating treatment efficacy for active ulcerative colitis / 南方医科大学学报

OBJECTIVE@#To assess the value of Improved Mayo Endoscopic Score (IMES) for evaluation of treatment efficacy for active ulcerative colitis (UC).@*METHODS@#We retrospectively analyzed the clinical and endoscopic data of 103 patients diagnosed with active UC in Beijing Tsinghua Changgung Hospital from January, 2015 to December, 2020. The severity of endoscopic lesions was determined by Mayo Endoscopic Score and the Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and the area of the endoscopic lesions was evaluated based on the Montreal classification system. The IMES was established by combining the MES with the Montreal classification.@*RESULTS@#Univariate analysis suggested that young patients (<40 years old), patients with extensive disease type (E3), patients with high endoscopic scores (MES=3, UCEIS>4, and IMES>4), and patients receiving advanced drug therapy (with systemic hormones, immunosuppressants, immunomodulators, and biological agents, etc.) had lower clinical and endoscopic remission rates. COX survival analysis showed that IMES≤4 was an independent risk factor for clinical and endoscopic remission. ROC curve indicated that the predictive value of IMSE≤4 for clinical and endoscopic remission (AUC=0.7793 and 0.7095, respectively; P<0.01) was better than that of Montreal (AUC=0.7357 and 0.6847, respectively; P<0.01), MES=2 (AUC=0.6671 and 0.5929, respectively; P<0.01), and UCEIS≤4 (AUC=0.6823 and 0.6459, respectively; P<0.01); IMES=5 had a better predictive value for patients with active UC undergoing colectomy tham E3 and MES=3.@*CONCLUSION@#IMES has good value in evaluating treatment efficacy for active UC.

The application of large flat-panel multifunction digital X-ray machine in digestive system / 中国医学装备

Objective: To evaluate the application value of large flat-panel multifunction digital machine in digestive system. Methods: Exam the gastrointestinal tract and biliary with dynamic detector, and then observe its advantages and disadvantages. Results: All the 13 gastrointestinal cancer lesions and 15 inflammatory lesions were shown clearly, including mucosa. Biliary tomography found two small stones, which were undetected by the general X-ray photography. The excellent rate of the photo was improved to 98%. Conclusion: The advantages of the flat panel detector include the wide range of display, clear image of digital pulse fluoroscopy spot film, the improvement of the diagnostic accuracy and the reduction in radiation dose. The disadvantage is that it is more inconvenient than the remote cradle gastrointestinal machine in rotating the position of the patient.
