Background The mitochondrial Na+/Ca2+exchanger, NCLX, plays an important role in the balance between Ca2+influx and efflux across the mitochondrial inner membrane in endothelial cells. Mitochondrial metabolism is likely to be affected by the activity of NCLX because Ca2+activates several enzymes of the Krebs cycle. It is currently believed that mitochondria are not only centers of energy produc-tion but are also important sites of reactive oxygen species (ROS) generation and nucleotide-binding oligomerization domain receptor 3 (NLRP3) inflammasome activation. Methods&Results This study focused on NCLX function, in rat aortic endothelial cells (RAECs), induced by glucose. First, we detected an increase in NCLX expression in the endothelia of rats with diabetes mellitus, which was induced by an injection of streptozotocin. Next, colocalization of NCLX expression and mitochondria was detected using confocal analysis. Suppression of NCLX expression, using an siRNA construct (siNCLX), enhanced mitochondrial Ca2+influx and blocked efflux induced by glucose. Un-expectedly, silencing of NCLX expression induced increased ROS generation and NLRP3 inflammasome activation. Conclusions These findings suggest that NCLX affects glucose-dependent mitochondrial Ca2+signaling, thereby regulating ROS generation and NLRP3 in-flammasome activation in high glucose conditions. In the early stages of high glucose stimulation, NCLX expression increases to compensate in order to self-protect mitochondrial maintenance, stability, and function in endothelial cells.

Objective By studying clinical features, treatment and prognosis of eosinophilic gastroenteritis of infants resulted from milk protein allergy an, to improve the diagnosis and treatment level of eosinophilic gastroenteritis. Methods 24 cases of infants which diagnosed eosinophilic gastroenteritis were chosen from June of 2010 to January of 2014 in children’s Hospital of XX province and By retrospective analysis clinical manifestations, endoscopic features, histopathology, treatment and prognosis of the 24 cases. Results The 24 cases who were vomiting, paroxysmal crying, abdominal distension (100.00%), which accompanied by haematemesis 23 cases (95.83%), 1case (4.17%) hematochezia, 17cases (70.83%) eczema, 21 cases (87.50%) mild to moderate anemia, 1 cases (4.17%) severe anemia, 19 cases (79.17%) the increasing of peripheral blood eosinophil cells, 8 cases (33.33%)the increasing of IgE of the serum and 4 cases (16.67%) the test of antibody of the Helicobacter pylori in Serum was positive; 3 cases (12.50%) were milk protein allergy by the detecting of food allergen-speciifc IgE antibodies, the endoscopic characteristics were hyperemia, edema, erosion, ulcer of gastric and duodenal mucosa. Among them, 24 cases (100.00%) were gastritis, 5 cases (20.83%) duodenitis and 1 cases (4.17%) duodenal ulcer. The histopathology of the 24 cases revealed that there were gastric or duodenal eosinophils infiltration (> 20/HPF) and were all associated with mast cell infiltration; By antisecretory, protection of the gastrointestinal mucosa and the obviating of milk protein had a satisfactory treatment effect, 24 cases of children with oral general formula milk test conifrmed that the milk protein allergy, The 3 cases of the patients were reviewed by 8~12 weeks after gastroscope, and the mucosa of the duodenum was smooth, Eosinophils were/HPF<8, mast cells were/HPF<5. Conclusion There are no speciifc clinical and endoscopic manifestations in eosinophilic gastroenteritis of infants resulted from milk protein allergy, gastrointestinal mucosa eosinophil inifltration and simultaneously are accompanied by abnormal mast cell inifltration;Mucosal type without the use of corticosteroids, through milk protein avoidance treatment can achieve satisfactory results, But definite diagnosis must rely on biopsy and eosinophils, combined with avoidance stimulation test of milk protein can further confirmed, But the excitation test should be at least 10 days of observation of children, and carefully recorded symptoms, so as not to delay the missed diagnosis of CMPA.
