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.

Objective To investigate the role of pancreatic β cell on pancreatic regeneration following experimental acute pancreatitis.Methods Eighty-seven SD male rats were randomly divided into four groups:control group ( n =15 ),STZ group ( n =24),L-Arg group ( n =24 ),STZ + Arg group ( n =24).60 mg/kg of STZ was administrated by intraperitoneal injection to induce the diabetes model.2.5 g/kg body weight of LArg was administrated by intraperitoneal injection to induce the acute pancreatitis model.The rats were sacrificed 1,3,5,7 d later and the serum levels of amylase and glucose were measured.Relative pancreatic weight (pancreatic weight/body weight) were measured.Pancreatic tissue underwent routine pathologic examination,and the percentage of area of necrosis and tissue transformation was calculated.The expression of Reg4 and insulin was performed by immunofluorescence.Results Serum level of glucose significantly increased after STZ injection.After L-Arg injection,serum level of amylase significantly increased,and there was pancreatic tissue edema,necrosis,infiltration of inflammatory cells,which suggested the successful model induction.The percentage of area of necrosis in STZ + L-Arg group was (71.6 ± 6.0) ％ at the 3rd day,which were significantly higher than (42.3 ± 4.0 ) ％ in L-Arg group; the percentage of area of transformation was (45.6 ± 5.4) ％,which were significantly lower than (78.5 ± 6.4) ％ in L-Arg group.Expression of Reg4 in pancreatic islets of STZ + L-Arg group was significantly lower than those in L-Arg group.Conclusions STZ impairs pancreatic β cells,aggravates pancreatic damage following L-arginine induced pancreatitis and inhibits pancreatic regeneration.

Objective To explore the susceptibility of Aspergillus biofilms to common antifungal drugs and molecular mechanisms of antifungal drug resistance of Aspergillus biofilms. Methods The susceptibility of planktonic spores of 22 clinical isolates of Aspergillus spp. to amphotericin B, caspofungin and voriconazole was evaluated by a standard broth microdilution method. Meanwhile, in vitro model of Aspergillus spp. biofilm was established for the 22 isolates, then the susceptibility of Aspergillus spp. biofilm to amphotericin B, caspofungin and voriconazole was evaluated by a method for antifungal susceptibility testing combined with colonmetric XTT-reduction assay. In addition, real-time reverse transcription (RT)-PCR was performed to determine the relative expressions of drug efflux pump genes and azole target enzyme genes during the formation of Aspergillus spp. biofilms. Results In terms of planktonic spores of Aspergillus spp., the- minimal inhibitory concentration (MIC) range was 0.5 to 2 mg/L for amphotericin B, 0.5 to 1 mg/L for voriconazole, and the minimal effective concentration (MEC) range was 0.125 to 0.25 mg/L for caspofungin. As far as Aspergillus spp.biofilms was concerned, the sessile minimum concentration required to inhibit the growth of 50% organisms (SMIC50) and 80% organisms (SMIC80) ranged from 2 to > 32 mg/L and from 8 to > 32 mg/L, respectively, for amphotericin B, from 32 to > 256 mg/L and from 256 to >256 mg/L respectively for caspofungin, from 4 to >256 mg/L and from 32 to > 256 mg/L, respectively for voriconazole. During the formation of Aspergillus spp.biofilms, no change was observed for the expression of any of the 7 tested drug efflux pump genes or azole target enzyme genes at 4 hours, while a significant increase was noted in the expression of AfuMDRl, CYP51B and CYP51A genes at 8 hours, as well as in the expression of AfuMDRl, AfuMDR2, AfuMDR4, CYP51A,CYP51B at 12, 16 and 24 hours. Of these genes, CYP51A showed the strongest increase in expression at the above 4 time points. The expression of AfuMDR3 and atrF experienced no significant change during the formation of Aspergillus spp. biofilms. Conclusions Compared to planktonic spores, Aspergillus spp. biofilms exhibit a decreased susceptibility to amphotericin B, caspofungin and voriconazole. After the formation of biofilms, the expression of drug efflux pump genes and azole target enzyme genes is elevated in Aspergillus spp.

Objective To study the MRI of cervical spinal cord injury without fracture and dislocation and explore of the apparent diffusion coefficient (ADC) of injured site related to the severity of injury. Methods 46 patients with cervical spinal cord injury without fracture and dislocation and 20 healthy controls were scaned with routine MRI and diffusion weighted imaging. The ADC value of site of injury and grades of Frankel's classification were analyze with the correlation. Results There were 22 cases with spinal cord edema, 8 cases with intramedullary hemorrhage, 14 cases with edema and hemorrhage, 2 cases without abnormal finding. The ADC of controls and patients were (1.05±0.12)×10-3 mm2/s, (1.21±0.23)×10-3 mm2/s (t=0.704, P<0.05). The ADC values positively correlated with the grades of Frankel's classification (r=0.407, P<0.05). Conclusion MRI may help to find the cervical cord injury in those without fracture and dislocation, and the ADC may be resposible to the severity of injury.

Objective:To assess the predictive value of histogram parameters derived from synthetic MRI for extramural venous invasion (EMVI) of rectal cancer.Methods:Totally 76 patients with pathologically proven rectal adenocarcinoma were enrolled in this retrospective study from November 2018 to December 2019 in Cancer Hospital, Chinese Academy of Medical Sciences. All participants underwent preoperative rectal MRI examination including MAGiC within 4 weeks before surgery. The status of EMVI on MRI was independently assessed by one junior and one senior radiologist. Histogram parameters were extracted from T 1, T 2 and proton density (PD) mapping, including mean, variance, maximum, minimum, 10 th percentile, median, 90 th percentile, energy, kurtosis, entropy and skewness. With postoperative pathological result as the gold standard, the patients were divided into EMVI-positive group ( n=18) and EMVI-negative group ( n=58). The Mann-whitney U test was used to compare the differences in histogram parameters between the two groups. The ROC curves were used to explore the predictive performance for assessing EMVI. The logistic regression analysis was used to combine the assessment of radiologists with parameters whose area under the ROC curve (AUC)>0.7. The Delong test was used to analyze the differences of diagnostic efficacy between different methods in predicting EMVI. Results:Significant differences of the energy of T 1, T 2 and PD mapping and skewness of PD mapping were observed between the EMVI-positive and EMVI-negative group ( P<0.05), with the AUC of 0.744, 0.728, 0.708 and 0.652. The AUC of junior radiologist in evaluating EMVI was 0.711, and the AUC of the combination with energy of T 1, T 2 and PD mapping was 0.817, showing a statistically significant difference ( Z=2.281, P=0.023). The AUC of senior radiologist in evaluating EMVI was 0.837, and the AUC of the combination with energy was 0.856. There was a significant difference in AUC between junior and senior radiologists in assessing EMVI ( Z=2.587, P=0.010), while there was no significant difference between junior radiologist combined with energy and senior radiologist ( Z=0.578, P=0.563). Conclusion:The histogram parameters based on quantitative mapping of synthetic MRI were useful for predicting EMVI of rectal cancer.
