ABSTRACT

ObjectiveTo determine the risk factors associated with colorectal adenoma among the residents in Nanchang city, and provide scientific evidence for primary preventive measures against colorectal cancer. MethodsA matched case-control study was conducted. A total of 155 patients newly diagnosed with colorectal adenomas during 2018‒2019 were selected as cases, and 155 healthy persons attending the screening as controls. Both the case group and control group completed the questionnaires on the risk factors. Conditional logistic regression analysis was performed using SPSS 25.0. ResultsAge, gender, and educational level were used for match between case group and control group. Conditional multivariate logistic regression analysis showed that salted and dried food intake(OR=5.634, 95%CI:1.308‒24.256), smoking(OR=3.266, 95%CI:1.419‒7.518), passive smoking(OR=3.125,95%CI:1.415‒6.898), and hyperlipidemia(OR=3.975, 95%CI:1.643‒9.618)were associated with higher risk of colorectal adenoma. In contrast, coarse grain intake ≥500 g/week(OR=0.377, 95%CI:0.177‒0.805) was a protective factor. ConclusionColorectal adenoma may be caused by multiple risk factors, particularly salted and dried food intake, smoking, passive smoking and hyperlipidemia. It warrants specific intervention to reduce the risk of colorectal adenoma.

ABSTRACT

Objective:To produce 161Tb from enriched 160Gd 2O 3 isotope-enriched target material and realize domestic production of the novel medical isotope 161Tb. Methods:The 160Gd 2O 3 isotope-enriched target material was irradiated with neutrons by the China Mianyang Research Reactor (CMRR). The no-carrier-added 161Tb product was obtained after the processes of target broken, sample dissolution, separation and purification with lanthanide (LN) resin and solution replacement with diglycolamide (DGA) column. Various key indicators such as γ spectral purity, metal impurity content, specific activity, radiochemical purity, and radioactive concentration were used to conduct the quality inspection and the control of 161Tb products. Results:161TbCl 3 of 33.4 GBq was obtained in a single time with the radioactive concentration of 16.8 GBq/ml, nuclear purity more than 99.9%, and radiochemical purity of 99.2%. Metal impurity content was met the established standards, with the specific activity of 6.02×10 17 Bq/mol. The radiochemical purities of 161Tb labeling with 1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid- D-Phe1-Tyr3-Thr8-octreotide (DOTATATE) after 0 and 72 h were 100% and 95.8% respectively. Conclusion:The preparation of no-carrier-added 161Tb by using LN resin has the advantages of high separation performance and high sample loading, which has great significance in the field of medical isotope preparation and lays a good nuclide guarantee for the research and development of domestic 161Tb-labeled drugs.

ABSTRACT

Objective To summarize the manifestation of pediatric eosinophilic gastroenteritis by ultrasound and discuss the diagnostic value of ultrasonography in pediatric eosinophilic gastroenteritis. Methods The ultrasonic appearances of 31 cases of pediatric eosinophilic gastroenteritis confirmed by clinics and pathology were reviewed and analyzed. Results Nineteen of 31 cases were observed in association with eosinophilic infiltration of other organs which were diagnosed as idiopathic hypereosinophilic syndrome.Eosinophilic cystitis was the most common among the complications(89.4%,17/19).Twelve of 31 cases were diagnosed as eosinophilic gastroenteritis without complications.The endoscopic appearances of eosinophilic gastroenteritis were nonspecific which include erythematous,hyperemia edema,and partiality erosion changes.Endoscopy demonstrates increased numbers of eosinophils in the propria of stomach and the duodenum.Ultrasound features of the gastroenteritis appeared diffuse or the parts of gastrointestinal tract.The most common sites of eosinophilic gastroenteritis were the stomach and duodenum.Involvement of muscle layer and serosal layer showed wall thickening of cyclic annular and uniformity.Ultrasound might show nodular or irregular thickening of the folds in the gastric antrum when the submucosa were thickening.The mucosal layer involvement was not easy to be found by ultrasound.The echo of serous layer and submucosa associated with the disease stage.The thickening of surrounding omentum and mesenteric tissue,echo enhancement and nonspecific hyperplastic mesenteric lymph nodes infiltrated with eosinophils might be present.Eosinophilic ascites could often be detected.Conclusions Ultrasound has obvious advantages in the diagnosis of pediatric eosinophilic gastroenteritis,and the ultrasonic changes of pediatric eosinophilic gastroenteritis are characterized.Ultrasonography can provide the possible diagnosis when combined with inflammatory of other organs,especially cystitis inflammatory changes.

ABSTRACT

Objective To explore the effect of continuous aspiration of subglottic secretion at different negative pressure levels on mechanical ventilation. Methods Toally 142 patients were randomized by way of lottery into the control group (n=70) and the experiment group ( n = 72 ): the control group received continuous negative pressure aspiration of subglottic secretion at a negative pressure of 60 mmHg while the experiment group did 30~40 mmHg for grade I of the sticky secretion , 40~60 mmHg for gradeⅡ~Ⅲof the sticky secretion, respectively. The two groups were compared in terms of the rate of ventilator associated pneumonia (VAP), airway mucosal injury and cough. Result There was no significant difference in the rate of ventilator associated pneumonia (P>0.05), but the rates of airway mucosal injury and cough were lower in the experiment group than those of the control group (P < 0.05). Conclusion It is reasonable to choose different negative pressure levels based on stickiness of the secretions for mechanical ventilation, for it can prevent the ventilator associated pneumonia and airway mucosal injury.

ABSTRACT

Objective To investigate the renoprotective effects of KB-R7943 on renal injury induced bycontrast media. Method Tubular epithelial cells were trested with varions cencentration of KB-B7943 (10-5,10-6 mol/L) for 12 hours before contrast media was used. After cells we, re incubated with contrast media (CM)(110 mgI/L) for 1 hour, cells injury was assessed by using LDH, and cell morphologic changes and cells apopto-sis were evaluated with inverted microscope and flow cytometry, respoelively. Intracellular Ca2+ and reactive oxy-gen species (ROS) were analyzed by using confocal microscope. The expression of Na+/Ca2+exchanger mRNAwas evaluated by RT-PCR. Mannitol with same osmolarity (20% mannitol, 770 mOsm/L) of CM was used as con-trol. One-way analysis of variance and q-test were used for comparison between groups. The simple linear correla-tion was employed to analyze the correlation. P < 0.05 was considered significant. Results Contrast media sig-nificantly induced tubular cells damage significantly and apoptosis at 1 hour after incubation, meanwhile, intracel-lular Ca2+ and ROS were inoreased progressively in CM group. KB-R7943 significantly attenuated cells damage andapoptosis in dose-dependent in association with decreased intracellular Ca2+ and ROS. Expression of Na+/Ca2+exchanger mRNA was not changed. Conclusions KB-R7943 has renoprotective effects on the contrast-media-in-duced renal tubular cyotoxicity
