Background:Pancreatitis is the main complication of ERCP,and a variety of risk factors will increase its risk. Studies showed that temporary pancreatic duct stent can reduce the incidence of post-ERCP pancreatitis (PEP). Aims:To study the efficacy and safety of prophylactic pancreatic duct stenting on preventing PEP in patients with risk factors. Methods:Patients undergone ERCP and accompanied with one or more PEP-associated risk factors from November 2013 to November 2016 at Huaibei People's Hospital were enrolled,and were divided randomly into pancreatic duct stenting group (observation group)and non-stenting group (control group). Serum levels of amylase at 4,24 and 48 hours after the procedure and incidence of PEP were compared between the two groups. Results:A total of 297 patients were enrolled, and 147 patients were in observation group,and 150 patients in control group. No significant differences in gender,age and ERCP disease spectrum were found between the two groups (P > 0. 05). Incidence of PEP was significantly decreased in observation group than in control group (6. 1％ vs. 16. 0％,P < 0. 05). Serum levels of amylase at 4,24 and 48 hours after the procedure were significantly decreased in observation group than in corresponding control group (P < 0. 05), however,no significant difference in incidence of hyperamylasemia was found between the two groups (59. 2％ vs. 54. 7％, P > 0. 05). Conclusions:Prophylactic pancreatic duct stenting may decrease the incidence of PEP in patients accompanied with PEP-associated risk factors, especially could decrease the severity of PEP. However, the incidence of hyperamylasemia is not decreased.

Objective To study the relationship between advanced liver fibrosis and peripheral neuropathy in patients with type 2 diabetes mellitus (DPN). Methods A total of 173 patients (89 men and 84 women) with type 2 diabetes who hos?pitalized in Tianjin Third Central Hospital within nearly three years (2013.02-2015.02) were divided into three groups ac?cording to non-alcoholic fatty liver disease (NAFLD) fibrosis score:group A (NFS≤-1.455), group B (-1.455

Objective To investigate the relationship between plasma levels of chromogranin A (CHGA) and adi-pose triglyceride lipase (ATGL) in patients with type 2 diabetes (T2DM) combined non-alcoholic fatty liver disease (NAFLD). Methods The plasma levels of CHGA and ATGL were assayed by enzyme-linked immunosorbent assay (ELISA) in T2DM patients with NAFLD (group A, n=74), T2DM without NAFLD (group B, n=76), and normal group (group NC, n=75). The correlation between CHGA, ATGL and other metabolic index was analyzed. Results The plasma level of CHGA was significantly higher in group A (83.15±9.46) and group B (70.90±2.75) than that of group NC (46.74±8.15, P<0.01), and the level of CHGA was significantly higher in group A than that of group B (P<0.01). The plasma level of ATGL was sig-nificantly lower in group A (21.36±13.42) and group B (40.29±22.83) than that of group NC (72.30±26.41, P<0.01), and the level was lower in group A than that of group B (P<0.01). There was a negative correlation between the plasma CHGA, AT-GL and carbohydrate oxidation rate in group A. There was a positive correlation between fasting insulin (FINS), insulin resis-tance index (HOMA-IR), free fatty acid (FFA) and fat oxidation rate in group A. There was a negative correlation between plasma level ATGL and body mass index (BMI), FINS, cholesterol (TC), triglyceride (TG) and HOMA-IR, meanwhile, it was positively correlated with FFA. The multiple stepwise regression analysis showed that FINS, ATGL and FFA were indepen-dent variables for CHGA. The Logistic regression analysis showed that plasma levels of CHGA, ATGL and FFA were the in-dependent predictors of T2DM with NAFLD. Conclusion The plasma levels of CHGA and ATGL are closely correlated with substance and energy metabolism, and the interaction between them may play an important role in the pathogenesis of T2DM with NAFLD .

Objective To evaluate the role of adrenal venons sampling (AVS) in differential diagnosis of subtypes in primary aldosteronism.Methods Twenty-two patients diagnosed as primary aldosteronism in the Third Central Hospital of Tianjin from November 201 1 to July 2014, were undergone AVS for measurement of plasma aldosterone and cortisol levels in each adrenal vein and infrarenal inferior vena cava.The data were compared with the results of the thin slice incremental scanning in adrenal and postoperative pathologic diagnosis.Other 8 patients, whose screening test and confirmed diagnosis did not support the primary aldosteronism, with nodule larger than 4 cm pathologically confirmed as non-functioning adrenal adenoma, were also recruited.Results Among all the 22 patients with primary aldosteronism, the incidence rate of hypertention was 95.4％, and the incidence of hypokalemia was 81.8％.Compared with idiopathic hyperaldosteronism patients, the patients with aldosterone producing adenoma had higher blood pressure and aldosterone level in plasma, but lower plasma potassium, while the clinical and biochemical index of the non-functioning adrenal adenoma group were within the normal range.The overall accuracy rate of adrenal CT in the diagnosis of subtypes of primary aldosteronism was 77.27％ (17/22), and the accuracy rates were 78.95％ (15/19) in aldosterone producing adenoma and 66.7％ (2/3) in idiopathic hyperaldosteronism, respectively.The accuracy rate of AVS was 100％ with the ratio of aldosterone to cortisol as the criterion.Conclusions Misdiagnose may occur when using CT scan only to differentially diagnose primary aldosteronism.Compared with CT imaging of the adrenal glands, AVS has higher coincidence rate and is an elective approach to establish the subtype diagnosis of questionable primary aldosteronism.
