Comparison between the Linked Color and White Light Imaging Combined Score in the Evaluation of High-Risk Population of Gastric Cancer.

BACKGROUND: For patients undergoing gastroscopy, it is necessary to judge whether there is Helicobacter pylori infection, atrophy/intestinal metaplasia. This study aimed to evaluate and compare the light color imaging (LCI) and white light imaging (WLI) combined score during gastroscopy. METHODS: Each included patient underwent normalized gastroscopy with WLI and LCI, and all notable findings were photographed. Four endoscopists reviewed the endoscopic images of each patient. The clinical information, results of the H. pylori tests were unavailable at review. The total LCI and WLI scores of each patient were calculated and their detection in high-risk populations of gastric cancer were evaluated. The diagnostic values of LCI and WLI for intestinal metaplasia were also calculated. RESULTS: In total, 392 patients were included in the study. The degree of inflammation and proportion of active inflammation cases were significantly higher in the H. pylori gastritis group than in the non-H. pylori gastritis group; their endoscopic manifestations were also different. The LCI combined score improved the diagnostic value of each individual observation index in the diagnosis of H. pylori infection compared with the WLI combined score. The sensitivity, specificity, and accuracy were 91.9% (91.9% vs 81.5%), 91.1% (91.1% vs 80.2%), and 95.8% (95.8% vs 93.2%), respectively. The accuracy of LCI in the diagnosis of intestinal metaplasia was higher than that of WLI (83.4% vs 69.6%). CONCLUSION: The LCI and LCI combined score improved the diagnosis of H. pylori gastritis and intestinal metaplasia, and it is considered valuable in identifying the high-risk population of gastric cancer.

Preliminary analysis on X-ray in youth neck type of cervical spondylosis with upper crossed syndrome / 中国骨伤

OBJECTIVE@#To analyze the X-ray characteristics in youth neck type of cervical spondylosis with upper crossed syndrome(UCS).@*METHODS@#The patients who had a neck type of cervical spondylosis with or without UCS were selected from January to October 2017, 20 cases in each group, and 10 normal volunteers were chosen in the study. X-ray examination of lateral and hyperextension-hyperflexion of cervical spine were performed to observe cervical spine angle, angular displacement and adjacent vertebral body slip.@*RESULTS@#The cervical spine angle was (-0.40±9.64)° in the UCS group, significantly less than (14.35±9.01)° in the normal group and (12.34±5.65)° in the non-UCS group(0.05).@*CONCLUSIONS@#In young patients who has a neck type of cervical spondylosis with UCS, the cervical curvature prone to straighten or reverse, the upper cervical flexion and extension are limited, while the lower cervical is in a flexion.
