OBJECTIVE: To assess the effect of early abdominal puncture drainage (APD) on autophagy and Nrf-2/HO-1 pathway in rats with severe acute pancreatitis (SAP) and explore the possibile mechanism. METHODS: Thirty-two male SD rats were randomly divided into sham-operated (SO) group, SAP group with retrograde injection of 4% sodium taurocholate, APD group with insertion of a drainage tube into the lower right abdomen after SAP induction, and APD + ZnPP group with intraperitoneal injection of 30 mg/kg ZnPP 12 h before APD modeling. Blood samples were collected from the rats 12 h after modeling for analysis of amylase and lipase levels and serum inflammatory factors. The pathological changes of the pancreatic tissue were observed with HE staining. Oxidative stress in the pancreatic tissue was detected with colorimetry, and sub-organelle structure and autophagy in pancreatic acinar cells were observed by transmission electron microscopy. The expressions of autophagy-related proteins and Nrf-2/HO-1 pathway were detected using RT-PCR and Western blotting. RESULTS: Compared with those in SAP group, the rats with APD treatment showed significantly alleviated pathologies in the pancreas, reduced serum levels of lipase, amylase and inflammatory factors, lowered levels of oxidative stress, and activated expressions of Nrf-2/HO-1 pathway in the pancreas. The ameliorating effect of ADP was significantly inhibited by ZnPP treatment before modeling. APD obviously reversed mitochondrial and endoplasmic reticulum damages and p62 accumulation induced by SAP. CONCLUSION APD treatment can suppress oxidative stress and repair impaired autophagy in rats with SAP by activating the Nrf-2/HO-1 pathway, thereby reducing the severity of SAP.

Diabetes patients and pre-diabetic patients are increasing worldwide. Type 2 diabetes starts with insulin resistance, and the long-term habit of stimulating insulin secretions causes insulin resistance and accumulates body fat to develop obesity and non-alcoholic fatty liver into diabetes. It also causes a variety of chronic diseases such as high blood pressure, polycystic ovary diseases, cancer and dementia. Insulin resistance is caused by an unbalanced lifestyle, and among other factors, the balance of the macronutrient is a very important factor. Koreans are characterized by high carbohydrate intake. Given the increasing prevalence of diabetes and the characteristics of Korean physical and eating habits, a more effective balance of diet education is needed. Therefore, it is very important for clinical dietitian to understand the carbohydrate and fat metabolism caused by insulin, and the concept of balanced diet for blood sugar control needs to be shifted from low-fat high-carbohydrate diet to low-carbohydrate high-fat diet.

PURPOSE: Glyphosate herbicides (GHs) are widely used and increasingly associated with poisoning cases. Acute pancreatitis (AP) is among the many complications associated with the toxicity of GHs. We investigated the relationship between incidence of AP and its prognosis in patients with GH poisoning. METHODS: This was a retrospective cohort study conducted at a single tertiary hospital between January 2004 and December 2014. We enrolled all patients presented to the emergency department with GH poisoning. The Clinical and laboratory variables were analyzed to investigate the relationship between GH intoxication and AP. RESULTS: We studied 245 patients. Incidence of AP after GH poisoning was 6.5%. Patients with AP (mean 66 years) were older than the non-AP group (56 years). Systolic blood pressure, Glasgow Coma Scale, and amount of ingested poison differed significantly between the two groups. In the blood tests, white blood cell count, alanine aminotransferase, glucose, potassium, amylase, and lipase showed significant differences. The pH, bicarbonate, and lactate levels also differed significantly. Patients with AP demonstrated higher incidence of respiratory failure, pneumonia, acute kidney injury, rhabdomyolysis, and intensive care unit stay time. Additionally, 30-day mortality (n=11, 68.8%) was significantly higher in the AP group. On multivariate analysis, adjusted age, amount of ingestion, and lactate correlated with occurrence of AP. CONCLUSION: The incidence of GH-induced AP was 6.5% with a 30-day mortality of 68.8%. The patient's age, ingested dosage, and lactate levels were associated with GH-induced AP.

Rats were exposed to 1 or 10 μg/mL bisphenol A (BPA) in water during pregnancy and lactation. Offspring rats were given normal water and a standard diet from weaning to postnatal day (PND) 50. Perinatal exposure to BPA resulted in significantly increased body weight, visceral adipose tissue, abnormal serum lipids, and lower adiponectin (ADP) levels in both female and male offspring rats. Liver adipose triglyceride lipase (Atgl) mRNA levels and ADP protein in visceral adipose tissue were significantly decreased in BPA-exposed offspring rats. In both female or male offspring rats, obesity and dyslipidemia induced by perinatal exposure to BPA were associated with down regulation of Atgl mRNA in liver and ADP protein in visceral adipose tissue.

Drug-induced pancreatitis accounts for 0.1~2.0% of all pancreatitis cases. Generally, the mechanism of drug-induced pancreatitis is an immune reaction, accumulation of toxic material, and/or ischemia. However, how dapsone causes pancreatitis remains unclear. A 61-year-old man presented with a 2-week history of epigastric discomfort. He had taken dapsone for 2 months to treat psoriasis. Laboratory findings showed high blood glucose levels and metabolic acidosis; however, hemoglobin A1c was low. Serum amylase and lipase levels were elevated to 125/4,479 U/L. Abdominal computed tomography was indicative of pancreatitis. There was no causative history of pancreatitis and no other medication history except dapsone. Thus, we reached a diagnosis of diabetic ketoacidosis (DKA) followed by dapsone-induced pancreatitis. The patient fasted and was treated with insulin administration and fluid hydration in accordance with treatment guidelines. After treatment, amylase and lipase decreased and symptoms subsided, but insulin injection was required to control blood glucose levels. Drug-induced pancreatitis is a very rare adverse effect of dapsone. Only four cases of pancreatitis related to dapsone could be found in a PubMed search. Moreover, diabetes caused by dapsone-induced pancreatitis has not been reported previously. Here, we report a case of DKA caused by dapsoneinduced acute pancreatitis.

OBJECTIVETo investigate the changes in serum amylase (AMY) and lipase (LPS) and their clinical significance in patients with acute paraquat poisoning (APP).

METHODSThe clinical data of 62 APP. patients who were admitted to Guangzhou 12th People's Hospital in 2014 were retrospectively analyzed. With clinical death being regarded as the end point of observation, the 62 patients were divided into survival group (n=32) and death group (n=30). The fasting venous blood of the patients on the 1st, 3rd, and 7th day after admission were collected, and the AMY and LPS levels were determined; the obtained data were compared between the two groups and analyzed statistically.

RESULTSThe AMY and LPS levels of the survival group on the 1st, 3rd, and 7th day after admission were significantly lower than those of the death group (P<0.05); the AMY and LPS levels of the death group on the 3rd day were significantly higher than those on the 1st day after admission (P<0.05); the survival group demonstrated no significant changes in AMY and LPS levels (P>0.05).

CONCLUSIONChanges in AMY and LPS levels in APP patients are reliable indicators for the determination of poisoning severity and prognosis.

OBJECTIVETo investigate the difference of liver enzyme levels and its correlation with serum ACE/ACE2 among yak and cattle on Qinghai-Tibetan plateau, and to further explore the biochemical mechanism of their liver of altitude adaptation.

METHODSThe serum samples of yak were collected at 3,000 m, 3,500 m, 4,000 m and 4,300 m respectively, meanwhile the serum samples of migrated cattle on plateau (2,500 m) and lowland cattle (1,300 m) were also collected. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), cholinesterase (CHE), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), serum lipase (LPS), angiotensin converting enzyme(ACE), angiotensin converting enzyme-2 (ACE2) in serum were measured by using fully automatic blood biochemcal analyzer. We analysed the differences of the above enzymes and its correlation with ACE/ACE2. We used one way analysis of variance (ANOVA).

RESULTSThe levels of ALT in 4,000 m group and 4,300 m group of yak increased significantly compared with other groups, there were no statistically significant differences in AST, CHE, GGT, ACE/ACE2 levels of yaks at different altitudes. As compared to lowland cattle, the serum levels of AST and CHE were increased, the level of LPS and ACE was decreased significantly, respectively, and especially, the ratio of ACE/ACE2 of migranted cattle reduced nearly two times. The levels of LPS were significantly correlated to the ratio of ACE/ACE2 in yak (r = 0.357, P < 0.01), and a high correlation between ALP and ACE/ACE2 in lowland cattle( r = 0.418, P < 0.05), But the biggest contribution rate of the ratio of ACE/ACE2 was only 17.5% for the changes of the levels of liver enzyme.

CONCLUSIONThe results indicated that with the altitude increased did not significantly influence the changes of liver enzymes' activities in mountainous yaks but not in cattle. However, all above these changes weren't actually correlated to the ratio of ACE/ACE2.

PURPOSE: Carbamate insecticides are potent cholinesterase inhibitors capable of causing severe cholinergic toxicity. Use of carbamate rather than organophosphate insecticides has been increasing. Compared with organophosphate poisoning, relatively few studies have investigated carbamate-associated acute pancreatitis. We investigated general characteristics and pancreatitis of carbamate poisoning and the predictors, among those readily assessed in the emergency department. METHODS: We performed a retrospective review of consecutive patients, aged over 18 years, who were admitted between January 2008 and April 2012 to an emergency department (ED) of an academic tertiary care center for treatment of carbamate poisoning. Patients who exhibited poisoning by any other material, except alcohol, were excluded. After application of exclusion criteria, patients were divided according to carbamate-induced pancreatitis and non-pancreatitis groups. RESULTS: A total of 41 patients were included in this study. Among these 41 patients, the prevalence of acute pancreatitis was 36.6% (15 patients). Initial blood chemistry tests showed a statistically higher glucose level in the pancreatitis group, compared with the non-pancreatitis group (222, IQR 189-284 vs. 137, IQR 122-175 mg/dL, P<0.05). Regarding clinical courses and outcomes, a significantly higher proportion of patients developed pneumonia [10 (66.7%) vs. 6 (23.1%), P<0.05] and had a longer hospital stay (7 days, IQR 6-12 vs. 5 days, IQR 2-11, P<0.05), but no difference in mortality, in the pancreatitis group vs. the non-pancreatitis group. In multivariate analysis, the initial glucose was showing significant association with the presentation of carbamate-induced acute pancreatitis (odds ratio 1.018, 95% confidence interval 1.001-1.035, P<0.05). CONCLUSION: Carbamate-induced acute pancreatitis is common, but not fatal. Initial serum glucose level is associated with acute pancreatitis.
