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 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.

Objective To investigate the expressions and mutual relationship of Galectin-3 andβ-catenin in endome?triosis (EM). Methods Immunohistochemistry was used to detect expression levels of Galectin-3 andβ-catenin and their mutual relationship in expression was also examined. Samples were collected from ectopic endometrium of patients with en?dometriosis (ectopic endometrium group, n=34), eutopic endometrium of patients with endometriosis (eutopic endometrium group, n=34) and normal endometrium from people without endometriosis (control group, n=30). Results The expressions of Galectin-3 were seen in 88.2%, 85.3%, 50.0%of cases in ectopic endometrium group, eutopic endometrium group and control group respectively. On the other hand, the expression ofβ-catenin were seen in 55.9%, 52.9%, 26.7%of cases in ecto?pic endometrium group, eutopic endometrium group and control group respectively. In EMs patients, the expression of Galec?tin-3 andβ-catenin were significantly higher in ectopic endometrium and eutopic endometrium than those in normal endome?trium group(P<0.05). Expression of Galectin-3 was positive correlated with expression ofβ-catenin(rs=0.512, 0.428, P<0.01). Conclusion Galectin-3 andβ-catenin may play important roles synergistically in the pathogenesis of endometriosis.

Objective To study diagnosis and treatment of rhabdomyosarcoma (RMS) in children.Method The clinical data of 43 children with RMS was retrospectively reviewed from Nov 2004 to May 2012.Their long-term survival was followed up.Forty-three children with RMS(male 26,female 17) in Beijing Tongren Hospital were enrolled.Their median age on diagnosis was 6 years old.We confirmed the diagnosis according to pathological diagnosis.Comprehensive treatment included chemotherapy,surgery and implantation of radioactive seeds,and so on.Statistical analysis was used on clinical data and treatment efficacy.Result The median follow up time of 43 cases with RMS in children was 31 mouths until May 2012.Four cases abandoned,39 cases were followed up.The cases of complete remission were 27(69％),and the cases of partly remission were 7 (18％),and the cases of dead were 5 due to cerebral metastasis.Overall survival rate was 87％ (34/39).Eight cases were treated with 125Ⅰ particles implants into its location,7 cases responded,1 case was invalid.Conclusion Although anatomic structure of RMS of head and neck was very complex,and the prognosis of it with metastatic disease was inferior,the muttidisciplinary treatment can still improve the clinical remission rate.In particular,high risk RMS with 125Ⅰ particles implants and large dose chemotherapy would be beneficial.
