To study the effect of glucagon-likepeptide 1(GLP-1)receptor agonist on insulin resistance and hepatic oxidative stress in rats with diabetes mellitus combined with nonalcoholic fatty liver disease. 36 male SD rats were served as the experimental animal and randomly divided into control group, model group, and GLP-1 group. The rats of control group were given routine diet with intraperitoneal injection of normal saline, those in model group were given high fat diet and intraperitoneal injection of normal saline, while GLP-1 group rats were fed with high fat diet and intraperitoneal injection of liraglutide. After 4 weeks of treatment, insulin resistance, lipid metabolism, liver injury and oxidative stress were all assessed. Serum fasting blood glucose, fasting insulin, total cholesterol, triglyceride, alanine transaminase(ALT), aspartate transaminase(AST)levels and total cholesterol, triglyceride contents in liver tissue, and as well as homeostasis model assessment for insulin resistance(HOMA-IR)levels of model group were significantly higher than those of control group, complex insulin sensitivity index(ISIcomp)level was significantly lower than that of control group; serum fasting blood glucose, fasting insulin, total cholesterol, triglyceride, ALT, AST contents and HOMA-IR levels of GLP-1 group were significantly lower than those of model group, ISIcomp level was significantly higher than that of model group; superoxide dismutase(SOD), glutathione peroxidase(GSH-Px), catalase(CAT)contents in liver tissue of model group were significantly lower, while malondialdehyde content and SOD, GSH-Px, CAT, NF-E2 related factor-2(Nrf-2), antioxidant response element(ARE), heme oxygenase-1(HO-1), quinone oxidoreductase-1(NQO-1), glutathione thiol transferase(GST)mRNA expression were significantly higher than control group; SOD, GSH-Px, CAT contents and SOD, GSH-Px, CAT, Nrf-2, ARE, HO-1, NQO-1, GST mRNA expression in the liver tissue of GLP-1 group were significantly higher, while malondialdehyde content was significantly lower than that of model group. GLP-1 receptor agonist reduces insulin resistance and liver oxidative stress injury in diabetic rats with nonalcoholic liver disease.

Objective To determine whether urinary neutrophil gelatinase-associated lipecalin (uNGAL) and urinary intedeukin-18 (uIL-18) are early markers of acute kidney injury (AKI) in critically ill patients. Methods Ninety-two critically ill patients were studied for one week after their enrollment into our hospital. During the study, 46 patients who met the RIFLE criteria were selected as AKI group and the remaining 46 patients without AKI taken as a control group. The two groups were matched for age, gender and illness severity. Urine samples were collected daily for one week. The receiver operating characteristic curve was used to evaluate the early diagnostic value of uNGAL, uIL-18 and serum creatininc (SCr). Results As compared with the levels obtained 3 days before the diagnosis of AKI, the uNGAL levels in the AKI group increased significantly (P <0. 05), while uIL-18 and SCr levels did not change 2 days prior to the diagnosis of A KI (all P > 0. 05). uNGAL and uIL-18 levels increased significantly (all P < 0. 05), while SCr levels did not change 1 day prior to the diagnosis of AKI in the AKI group (P > 0. 05). The levels of uNGAL, uIL-18 and SCr did not change significantly in the control group during the study period (all P > 0. 05). Three days before the diagnosis of AKI, concentrations of uNGAL, uIL-18 and SCr were not the predictive of AKI. Two days before the diagnosis of AKI, the area under the curve (AUC) of uNGAL was 0. 840 (95% CI 0. 672-1. 009, P < 0. 05), which indicated that uNGAL was the predictive of AKI while uIL-18 and SCr were not. One day before the diagnosis of AKI, the AUC of uNGAL and ulL-18 were 0. 830 (95 % CI 0. 711-0. 950, P < 0. 05) and 0. 818 (95 % CI 0. 697-0. 938, P < 0. 05), indicating that uNGAL and uIL-18 were the predictive of AKI while SCr was not. Conclusion uNGAL and uIL-18 may be the early predictive markers of AKI in critically ill patients.

Objective To discuss the effective nursing measures in interventional therapy for deep vein thrombosis (DVT) of lower extremities in order to improve the successful rate of the procedure and to decrease the occurrence of complications. Methods Comprehensive nursing measures, including general nursing care, specific nursing care and emergency nursing care, were employed in 63 DVT patients receiving interventional therapy. Clinical response and complications were observed. Results After the treatment, the disorder was cured in 31 cases, while excellent result was seen in 26 cases and obvious improvement in 6 cases. During the procedure, bleeding at puncture site occurred in 16 cases, pulmonary embolism in 2 cases and cerebral hemorrhage in one case. No death occurred. Conclusion Comprehensive nursing measures can effectively prevent or reduce the occurrence of complications, decrease the mortality rate. Therefore, Comprehensive nursing measures are the most helpful nursing care for DVT patients receiving interventional therapy.

The association rules in data of traditional Chinese medicine prescriptions were analyzed using SQL Server 2008,which showed that 17 core compatible drug pairs were in line with the association rules.For example,platycodon grandiflorum combined with liquorice,known as Liquorice and Platycodon Decoction,can treat the principal and secondary aspects of a disease by ventilating the lungs and resolving the phlegm,removing the toxic substances and relieving the sore throat.Mining compatible drug pairs by analyzing their association rules can provide evidence for their clinical application.

Objective To study the relationship between the grading of schistosomiasis japonica hepatic lesions by B-ultrasonography and the portal vein and splenic vein haemodynamics. Methods The grades of 125 schistosomiasis patients’ hepatic lesions were determined by Doppler ultrasonography according to the method recommended by WHO/TDR. The portal vein and splenic vein inner diameters and blood flow velocity were examined and the portal vein and splenic vein volumes of blood flow were calculated in the patients above mentioned and 51 normal persons. Results The inner diameters, blood flow velocity and volumes of blood flow of portal vein and splenic vein in the patients were significantly different from those in the normal persons, and also there were significant differences among the patients with different degrees of fibrosis. Conclusions The changes of schistosomiasis patients’ portal vein haemodynamics is connect with the liver parenchyma characteristics. The step up of the ratio of blood flow volume of splenic vein with the portal vein is breakdown with the aggravate of the hepatic lesion.

A method was developed for simultaneous determination of pyrrolizidine alkaloids and isoquinoline alkaloids in honey by dispersive solid phase extraction and high performance liquid chromatography-tandem mass spectrometry ( QuEChERS-HPLC-MS/MS) . The honey samples were extracted with acetonitrile solution and cleaned up with PSA absorbent. Agilent Poroshell 120 SB-C18 chromatographic column was used to separate alkaloids with high sensitivity and satisfactory resolution. The identification and quantification were achieved by using electrospray ionization in positive ion mode ( ESI+) with multiple reaction monitoring (MRM). Matrix-matched calibration curves with good correlation coefficients (R2>0. 99) were obtained in the concentration range of 0. 1-100 μg/L. The recoveries of the spiked samples at 1-100 μg/kg were in the range of 70% to 110% with the RSD of intra-day and inter-day lower than 15% and 20%, respectively. The limits of detection ( LOD) and limits of quantification ( LOQ) for all alkaloids were 0. 3 and 1. 0 μg/kg, respectively. This method was successfully applied to the simultaneous determination of pyrrolizidine alkaloids and isoquinoline alkaloids for quantification and confirmation in honey samples.
