Objective: To evaluate pharmacokinetic and pharmacodynamic of repaglinide tablets in Chinese subjects.Methods: Twenty healthy male volunteers were enrolled in the study. A single dose (4 mg) of repaglinide tablets was givenorally. Plasma concentrations of repaglinide were determined by HPLC method. Blood glucose and serum insulin leve1s weremeasured by biochemistry and radioimmunoassay methods respectively. Results: Plasma concentration-time curve conformedto one-compartment open model. The pharmacokinetic parameters were as follows: tmax (0. 75?0.43 ) h,cmax (54.44?24.97)ng/ml, t1/2 (0. 80?0. 31) h, MRT (1. 55?0. 41) h, C1/F (61. 43?20. 10) L/h and AUC (73. 34?29.95) h? ng/ml. Thelevel of serum insulin was raised and the level of blood glucose decreased after administration of repaglinide. The highest levelof serum insulin was (l26. 24?95.93) mU/L at 0.75h and blood glucose level reached its lowerest vaIue (2. 34I0.44) mmol/L 1 h after oral administration. Conclusion: Repaglinide is characterised by fast-acting and short effects on in-sulin secretion. It decreases serum glucose level by stimulating insulin secretion from the pancreatic ?-cells. It is a novel oralprandial glucose regulator for the treatment of type 2 diabetes mellitus.

OBJECTIVETo determine the cause of acute poisoning occurred in a factory in Yangjiang city, Guangdong province.

METHODSIn a cross-sectional study, interviews were conducted with the administrators of the factory and the local physician. A review was conducted on the water system used for industrial purposes and a separate system used by workers for drinking water. Treatment and discharge of industrial waste water were examined. Face-to-face interview was conducted to identify risk of exposure for illness among workers.

RESULTSA total number of 36 cases were identified in the plant and the attack rate was 16.4% (36/220). The incubation period (time between drinking polluted water and the onset of symptoms) had a median of 90 minutes (range: 30 - 230 minutes). Consuming water at the factory increased the attack rate and a dose-response effect was identified (chi(2)(trend) = 79.115, P < 0.01). The nitrite content of residuals in drinking water exceeded the WHO standard (1 ppm).

CONCLUSIONSThe accident of acute poisoning was due to drinking water contaminated with sodium nitrite. The prevention of drinking water contaminated by toxic chemicals like sodium nitrite, and the design of industrial and potable water supply system need to be carefully reviewed. Regulations should be developed and enforced to minimize the impact of industrial waste water discharges to guarantee the access to clean drinking water.

Objective To observe the effects of Lianggesan on serum citrulline and intestinal fatty acid binding protein (IFABP) levels in patients with mechanical ventilation and acute gastrointestinal injury (AGI). Methods Eighty patients with mechanical ventilation and AGI admitted to Tianjin First Center Hospital from May to December 2017 were divided into a conventional treatment group and a traditional Chinese medicine (TCM) treatment group according to different treatment methods, 40 cases in each group; 10 patients with mechanical ventilation but without AGI were selected as a control group. All patients were given invasive mechanical ventilation after admission, and the gastrointestinal tract intervention was carried out according to AGI grading treatment process; Lianggesan (compositions:forsythia suspensa 30 g, scutellaria 10 g, gardenia 10 g, bamboo leaf 10 g, rhubarb 10 g, mint 6 g, mirabilite 6 g, licorice 15 g) was added to the TCM treatment group on the basis of the conventional treatment. The above TCM drug used was a single Chinese medicine granule produced by Jiangyin Tianjiang Pharmaceutical Co., Ltd. Each single Chinese herbal granule was proportionally poured into 200 mL boiling water at 80-100 ℃, 100 mL each time, twice daily nasal feeding for one week. The changes of serum citrulline and IFABP levels were observed before and 1, 3, 5 and 7 days after treatment in the three groups. Results Before treatment, serum citrulline levels in the conventional treatment group and the TCM treatment group were significantly lower than those in the control group (μmol/L: 19.84±4.74, 20.84±4.65 vs. 28.89±2.18, both P < 0.05), and IFABP levels were significantly higher than those in the control group (ng/L:571.89±42.89, 552.49±44.78 vs. 155.68±22.95, both P < 0.05), there were no significant differences between the conventional treatment group and the TCM treatment group (P > 0.05); with the extension of treatment time, the levels of citrulline in the conventional and TCM treatment groups were decreased first and then increased gradually, reaching the valley value on the first day of treatment [the two groups were (16.12±4.44), (18.49±4.59) μmol/L] respectively, and then increased gradually, reaching the peak value on the 7th day of treatment, the increased range of citrulline in the TCM treatment group was more obvious than that in the conventional treatment group (μmol/L: 26.77±4.18 vs. 22.75±3.07, P < 0.05), and the treatment lasted for 5 days, and 7 days, the level of citrulline in the TCM treatment group was close to that in the control group; the IFABP levels in the conventional treatment group and the TCM treatment group were increased first and then decreased gradually, reaching the peak value on the first day of treatment [the two groups were (654.23±63.24), (630.32±49.11) ng/L] respectively, and then decreased gradually, reaching the trough value on the 7th day of treatment, the degree of decrease in the TCM treatment group was more obvious than that in the conventional treatment group (ng/L: 262.21±30.89 vs. 375.43±44.43, P < 0.05), but the level of IFABP in the TCM treatment group was still significantly higher than that in the control group (ng/L: 262.21±30.89 vs. 158.95±29.34, P < 0.05). Conclusion Lianggesan can elevate the serum citrulline level, reduce the serum IFABP level, and effectively improve the intestinal function of patients with mechanical ventilation and AGI.
