Objective To investigate the expression of malondialdehyde ( MDA) in esophageal mu-cosa of different types of gastroesophageal reflux disease ( GERD) patients and its role in the esophageal in-flammation. Methods According to the inclusion and exclusion criteria, 42 patients hospitalized in the the Xinjiang Uygur Autonomous Region People's Hospital from December 2017 to October 2018 were selected as the research group. 8 healthy subjects completed physical examination were set up as healthy control group. GERD completed GERDQ score, 24 h pH monitoring, and taken 3 cm on the dentate line of the esophagus as a specimen. The study group was divided into non-erosive reflux disease (NERD) group (17 cases) and Ero-sive reflux disease [erosive esophagitis (RE)] group (25 cases). Then hematoxylin-eosin (HE) staining, immunohistochemistry, real-time polymerase chain reaction ( qPCR ) , enzyme-linked immunosorbent assay (ELISA) methods were used to detect inflammation, oxidative stress (MDA), antioxidant enzyme [manga-nese superoxide dismutase (Mn SOD), glutathione (GSH), catalase (CAT)], and proinflammatory cyto-kines [monocyte chemotactic protein-1 (MCP-1), interlukin-8 (IL-8), tumor necrosis factorα(TNF-α)]. Results There was no significant difference in body mass index ( BMI ) between the three groups ( P >0. 05). 24 h pH monitoring of esophagus showed that the indexes of weak acid reflux (40. 05). In RE group , the infiltration of immune cells (neutrophils, eosinophils), nipple lengthening, edema and other inflammatory changes were found in the esophageal mucosa, and the inflammation score reached the peak, which was signif-icantly higher than that in NERD group, with statistical significant difference (P<0. 001). The positive ex-pression of MDA in the two groups ( NERD, RE) was higher than that in the control group, and the MDA ex-pression in the RE group was almost covered with the full layer esophagus. The serum MDA concentration in the NERD and RE groups was significantly higher than that in the control group (P<0. 001). Compared with the NERD group, the serum MDA in the RE group reached the peak (P<0. 01). The relative expression of mRNA ( Mn SOD, GSH and CAT) in NERD group and RE group was significantly decreased, and there was a significant difference between the three groups (P<0. 001). Compared with the NERD group, the mRNA expression level of Mn SOD and CAT in RE group was significantly decreased (P<0. 01). The relative ex-pression of mRNA (MCP-1, IL-8, TNF- α) increased significantly in the two groups (NERD, RE), and there was a statistically significant difference between the three groups ( P <0. 001 ) . Compared with the NERD group, the expression of its inflammatory factors in the RE group significantly increased (P<0. 01). Conclusions The expression level of MDA in different types of GERD is significantly higher, which may be closely related to esophageal inflammation induced by acid reflux.

Objectives To analyze the clinical and laboratory characteristics,and characteristics of population distribution as well,and to provide the scientific data for the adult measles control.Methods Using descriptive epidemiology and statistical approach to analyze the clinical information for the adult measles patients hospitalized in People's Hospital of Xinjiang Uygur Autonomous Region of Urumqi city in Xinjiang province of China between Oct.2007 and Mar.2008.Results The average age of all the patients was 25.5 years old.63 patients had fever and most of them were at 39.1～40.0℃.61(96.8%) patients had rash,and 54 (85.7%) patients had koplik spots at the moment of hospitalization.26 (41.3%) patients had the complications of acute tracheobronchitis.And the chest radiograph of 28 (44.4%) patients showed the inflammatory shadow.The proportion of the neutrophils of 11 (17.5%) patients was high level in the blood testing.The alanine aminotransferase of 18 (28.6%) patients were elevated.All the patients were recovery.Conclusion More and more adult measles patients occurred in China in recent years.The clinical characteristics among the patients was variable.It is necessary to discuss and make a decision about the issue of supplementary immunization for adult population in China.
