Objective:To investigate the safety and efficacy of endoscopic treatment for sporadic non-ampullary descending duodenal adenoma, and to analyze high-risk endoscopic features of malignant adenoma.Methods:Data of 54 patients diagnosed as having non-ampullary descending duodenal adenoma in Nanjing Drum Tower Hospital from November 2012 to September 2019 were retrospectively studied. The patients were divided into two groups, the high-grade intraepithelial neoplasia/adenocarcinoma (HGIN/AC) group and the low-grade intraepithelial neoplasia (LGIN) group according to pathological grade. Clinical features including gender, age, size and color of lesions, therapeutic methods, complications and postoperative follow-up results were analyzed.Results:A total of 54 patients were divided into the HGIN/AC group ( n=12) and the LGIN group ( n=42). There were significant differences in size or color of lesions between the two groups (both P<0.05). All 54 patients received endoscopic treatment. Biopsy, endoscopic mucosal resection and endoscopic submucosal dissection were performed on 8, 32 and 14 cases, respectively. A small perforation was found and clipped during operation without any complications. There were 2 cases of delayed hemorrhage, and the bleeding stopped under endoscopic treatment. The mean follow-up time was 2-58 months with no recurrence. Conclusion:Endoscopic treatment is safe and effective for non-ampullary descending duodenal adenoma. Lesions of size larger than 10 mm and those with a red surface have higher malignant tendency.

Objective To investigate the relationship between eosinophil and in-stent restenosis in acute coronary syndrome patients. Methods One hundred and fifity-one ACS cases werenenrolled in this study. According to the results of coronary angiography (the stented segment lumen loss over 50% was judged to be ISR), patients were divided into the restenosis group and the non-restenosis group. Results Based on the logistic analysis, no significant association was found between eosinophil and ISR, and even after adjustment of related risk factors (P > 0.05). The stratification analysis showed that the high level of eosinophil might increase the risk of ISR in ACS patients with history of hypertension (P = 0.038) and myocardial infarction (P = 0.032). Conclusion Eosinophil may be associated with the risk of ISR in ACS patients with history of hypertension and myocardial infarction. The underlying mechanisms need to be elucidated in further study.

Objective To investigate the incidence and influencing factors of aldosterone escape in patients with non-diabetic nephropathy by RASI-therapy. Methods A total of 104 patients with non-diabetic nephropathy were treated with ARB or combination therapy of ACEI and ARB in a mean follow-up period of 12 months. Aldosterone escape was determined according to the change of plasma aldosterone concentration before and after treatment during 6-month and 12-month ACEI/ARB treatment, while the influencing factors of aldosterone escape in patients with non-diabetic nephropathy was also analyzed after therapy with RASI . Results In 12 months, the incidence of aldosterone escape was significantly higher than that in 6 months (26.92% vs. 14.42%, P = 0.007). After 12-month treatment, the difference was statistically significant in incidence of aldosterone escape among different stages of CKD (P = 0.027). Compared with 6-month incidence of aldosterone escape in the losartan group, 12-month incidence increased evidently (P = 0.020). The Ald level was positively correlated with urinary protein excretion and the Scr level (r = 0.431, P = 0.003 and r = 0.336, P = 0.009, respectively), and negetively correlated with levels of the eGFR (r = -0.275, P = 0.006). Univariate Logistic regression demonstrated that risk factors of aldosterone escape included pre-treatment values of the urinary protein excretion (OR = 3.671, P = 0.028) and the eGFR (OR = 0.972, P = 0.019). Multivariate Logistic model revealed pre-treatment values of the eGFR was positively associated with aldosterone escape (OR = 0.970, P = 0.012). Conclusion The incidence of the aldosterone escape increases along with the time of treatment. Renal function has correlated with aldosterone escape and pre-treatment value of the eGFR is an independent risk factor of aldosterone escape.
