RESUMO
Colorectal cancer is one of the most common malignant tumors in China. It poses a serious threat to health and its morbidity and mortality are increasing year by year. There are defects in early diagnostic markers and disease activity progression indi-cators for clinical applications. Lipidomics helps to analyze the etiology,pathological progression and clinical diagnosis of colorectal cancer by comparing differences in lipid metabolites in vivo,providing a new method and platform for research of colorectal cancer. This review is aimed at the application of lipidomics in colorectal cancer.
RESUMO
Objective The aim of this study was to investigate the application and clinical value of ultra-fine nasal endos-copy in the diagnosis and treatment of digestive tract stenosis. Methods A retrospectively investigation of 160 cases of nasogastricos-copy in esophageal,gastroduodenal and colorectal stenosis lesions,the detection rate of lesions under the stenosis and endoscopic treat-ment were analyzed from January 1,2016 to December 31,2017. Results In 102 cases of diagnostic examination,the passing rates of nasogastricoscopy in esophageal,gastroduodenum and colorectal stenosis were 76. 92% ,50. 00% and 88. 00% ,respectively. In the ca-ses which the endoscope could successfully pass the stenotic lesions, the detection rates of new lesions below the stenosis were 8. 89% ,0 and 27. 78% ,respectively,in esophageal,gastroduodenum and colorectal stenosis. A total of 58 cases of digestive tract ste-nosis were treated with endoscopic gastroscopy. Among them,46 cases had stenosis and the pass rate was 79. 31% . Conclusion Ultra-fine nasal endoscopy can significantly improve the completeness and accuracy of endoscopic diagnosis in patients with digestive tract stenosis that cannot be passed by standard gastrointestinal endoscopy. It can also be used for endoscopic treatment of digestive tract stenosis.
RESUMO
Objective To investigate the dynamic changes of Th 17 ,NK and IFN-γ,IL-17 in periop-erative patients with lung cancer .Methods Twenty cases of patients with lung cancer surgery were chosen ran-domly.Ten cases of healthy were used as control .We detected the express of Th17,NK,IFN-γand IL-17.Re-sults Compared with the control group , the levels of Th17 and IL -17 increased significantly in lung cancer group(P<0.05);Compared with the pre -operation,the levels of Th17 and IL-17 increased significantly after 1st day of lung cancer surgery .However,the levels of NK and IFN -γdecreased significantly .The expression of Th17 and IL-17 decreased obviously after 5 days of lung cancer surgery .However,the levels of IFN -γin-creased significantly(P<0.05).The correlation analysis showed that there was a positive correlation between Th17 and IL-17A,NK and IFN-γof peripheral blood with lung cancer patients (P<0.01),negative correla-tion between Th17 and NK,IFN-γof peripheral blood with lung cancer patients (P<0.05).Conclusion The immune suppress before activating at perioperative ,it is important for lung cancer patients to detect the levels of Th17,IL-17,NK,IFN-γin peripheral blood .
