To study the in situ intestinal absorption of five oligosaccharides contained in Morinda officinalis How. (sucrose, kestose, nystose, 1F-Fructofuranosyinystose and Bajijiasu). The absorption of the five oligosaccharides in small intestine (duodenum, jejunum and ileum) and colon of rats and their contents were investigated by using in situ single-pass perfusion model and HPLC-ELSD. The effects of drug concentration, pH in perfusate and P-glycoprotein inhibitor on the intestinal absorption were investigated to define the intestinal absorption mechanism of the five oligosaccharides in rats. According to the results, all of the five oligosaccharides were absorbed in the whole intestine, and their absorption rates were affected by the pH of the perfusion solution, drug concentration and intestinal segments. Verapamil Hydrochloride could significantly increase the absorptive amount of sucrose and Bajijiasu, suggesting sucrose and Bajijiasu are P-gp's substrate. The five oligosaccharides are absorbed mainly through passive diffusion in the intestinal segments, without saturated absorption. They are absorbed well in all intestines and mainly in duodenum and jejunum.

Three cases of Langerhans cell histiocytosis (LCH)with central diabetes insipidus as the first manifestation were reported, with the summary of their clinical manifestations, laboratory examinations, imaging examinations, pathological results, diagnosis process, and treatment response. All three patients presented with central diabetes insipidus in the early stage. The pituitary magnetic resonance imaging (MRI)showed thickened pituitary stalks, and all lost the normal high signal of the posterior pituitary. Two patients showed isolated hypothalamic-pituitary lesions, while one case showed pituitary and thyroid systems involvement. Pathological findings showed typical Langerhans cells, immunohistochemistry showed positive for S-100, CD1a, Langerin. The clinical manifestations of LCH manifested distinct heterogeneity, which is easy to be misdiagnosed and left out. The diagnosis should be confirmed by pathological examination. The biopsy of isolated hypothalamic-pituitary lesions is difficult. It is recommended to actively screen other organs to increase the probability of biopsy. LCH-induced neurohypophysis requires life-long hormone replacement therapy.

Astragalus adsurgens seed is one of the most common adulterants of Astragali Complanati Semen in the market, whose morphological characteristics are very similar with A. complanatus seeds (Astragali Complanati Semen). Many identification methods have been reported, such as morphological identification, fluorescence method, ultraviolet spectrophotometry, TLC, HPLC, protein electrophoresis and so on, but there's no much about microscopic identification. In the present study, the morphological characteristics and microscopic characteristics of these two seeds were investigated, which could provide scientific evidence for the identification and classification of Astragali Complanati Semen. Our results showed that these two seeds were slightly different in the color and the appearance, but significantly different in the microstructure of the seed coat and the hilum, and the distribution of fat droplets in the cotyledon cells. So these microscopic characteristics can be applied for the identification of Astragali Complanati Semen.

Objective To study MRI findings of pancreatic ducts of piglets with chronic pancreatitis (CP) induced by pancreatic duct ligation and analyze the relationship between pancreatic duct changes in piglets with CP and the pathological severity of CP. Methods Thirty healthy piglets were included in this study. Five piglets were randomly selected as normal control group, and the remaining 25 piglets were served as the experimental group. The duct ligation operations were performed on experimental group. After 2 to 18 weeks, pancreas and pancreatic ducts were observed on MRI. Then the pancreas was removed and graded into three types by histopathology. The relationship between the diameter of pancreatic duct or the pancreatic branch displaying rate and the severity of CP was analyzed by Spearman correlation coefficient. Results CP was found in 21 piglets( 84. 0% ) in the experimental group including mild ( n = 7 ), moderate ( n = 8 ) and severe( n = 6) pancreatitis. Pancreatic ducts were shown in mild CP and the edge of pancreatic ducts was irregular in three cases. The dilated RPD, LPD and MPD constituted the "person" form in moderate and severe CP. The diameter of pancreatic ducts was(0. 9 ±0. 3)mm, (2. 9 ± 1.4)mm and (4. 8 ± 1.2)mm in mild, moderate, and severe CP respectively. The expansion extent of pancreatic ducts was correlated with the severity of CP of piglets (r = 0. 837, P < 0. 05). The pancreatic branch displaying rate increased with the increase of the severity of CP ( r = 0. 990, P < 0. 05 ); the displaying rate was 0/7 for mild, 3/8 for moderate, and 5/6 for severe CP. Conclusions The dilated pancreatic ducts with "person" form in piglets with obstructive CP created by pancreatic duct ligation. The pancreatic duct changes on MRI reflect the severity of CP of piglets.

Objective To explore the correlation between hypokalemia and sudden death in young and middle-aged people. Methods One hundred and twenty-nine young and middle-aged patients with sudden death during treatment were selected as observation group. Then 100 cases of healthy volunteers were randomly selected as control group. The incidence of cardiovascular disease, incidence of hypokalemia and intake of potassium were compared between 2 groups. Results The incidences of hypertension, arrhythmia, myocardial infarction, heart failure and hypokalemia in observation group were significantly higher than those in control group: 17.05% (22/129) vs. 5.00%(5/100), 13.18% (17/129) vs. 2.00% (2/100), 26.36% (34/129) vs. 9.00% (9/100), 9.30% (12/129) vs. 1.00% (1/100) and 55.04% (71/129) vs. 12.00% (12/100), and there were statistical differences (P<0.01). The ratios of higher, common, lower intake of potassium in observation group were 1.55%(2/129), 27.91% (36/129) and 70.54%(91/129), in control group were 15.00% (15/100), 58.00% (58/100) and 27.00% (27/100), and there was statistical difference (P<0.01). Logistic regression analysis result showed that hypertension, arrhythmia, myocardial infarction, heart failure, hypokalemia and lower intake of potassium were the risk factor for sudden death (P<0.01). The incidences of hypertension, arrhythmia, myocardial infarction and heart failure in hypokalemia patients were significantly higher than those in normokalemia patients: 28.92% (24/83) vs. 2.05% (3/146), 19.28% (16/83) vs. 2.05% (3/146), 44.58%(37/83) vs. 4.11% (6/146) and 13.25% (11/83) vs. 1.37% (2/146), and there were statistical differences (P<0.01). The incidence of hypokalemia in people with lower intake of potassium was significantly higher than that in people with higher and common intake of potassium: 56.78% (67/118) vs. 2/17 and 14.89%(14/94), and there was statistical difference (P<0.01). Conclusions There is a significant correlation between hypokalemia and sudden death in young and middle-aged people. Preventive measures of sudden death should be made according to serum potassium level in clinic. People should pay attention to the uptake of potassium in daily life.
