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.

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 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.

Objective Toinvestigate the changes of liver and kidney function and morphology of the renal artery of the metabolic syndrome (MS) rats.Methods The rats were respectively fed with ordinary or high-fructose diet for 10 weeks,and then took the blood and anatomical observation,to explore the changes of liver and kidney function and morphology of the renal artery of the rats.Results The serum levels of ALT,AST,UA,BUN,CR in the control group and MS group were gradually increased with the feeding time.But those in MS rats were significantly increased than the control rats.MS rats showed dysfunction of liver and kidney,which similar to the clinical MS cases.Compared with the control group,the renal artery of MS rats had the same pathological changes as MS cases,presented with intima uneven thickening and structural disorder,medial smooth muscle cells hyperplasia to intimal,the internal elastic membrane with different degrees of damage and fracture,the film elastic fibers thickening and structural disorder,smooth muscle cell proliferation apparently,medial obvious thickening.Conclusion MS rats have mild dysfunction of liver and kidney and abnormal changes in intima and tunica media of renal artery.

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 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 evaluate the effects of sedation with propofol or dexmedetomidine on volume responsiveness in critically ill patients with acute circulatory failure. Methods Ninety?one critically ill patients with acute circulatory failure, aged 20-90 yr, weighing 40-80 kg, requiring sedation with propofol or dexmedetomidine, of Acute Physiology and Chronic Health Evaluation Ⅱ scores 12-47, of Sequential Organ Failure Assessment scores 1-18, and of NYHA Ⅰ or Ⅱ, were included. The patients were randomly divided into 2 groups using a random number table: propofol group ( n = 45 ) and dexmedetomidine group ( n=46) . Before and after propofol or dexmedetomidine sedation, when Richmond Agitation Sedation Scale score reached -2 or -1 ( BIS value 60-75) ( after sedation) , passive leg?raising (PLR) test was performed to evaluate volume responsiveness. An increase in cardiac index (ΔCI) ≥10% after PLR was considered to be a positive response, whereas ΔCI<10% after PLR was considered to be a negative response. The patients who presented with negative responses before sedation served as negative volume responsiveness subgroups ( N subgroups ) , that was PN subgroup and DN subgroup. Results The positive rates of volume responsiveness were 64% ( 14 cases) and 25% ( 5 cases) in PN and DN subgroups, respectively. The positive rates of volume responsiveness were significantly higher after sedation than before sedation in PN and DN subgroups. Compared with DN subgroup, the positive rates of volume responsiveness were significantly increased after sedation in PN subgroup. Conclusion For the critically ill patients with acute circulatory failure, both propofol and dexmedetomidine sedation can improve volume responsiveness, and propofol provides better efficacy than dexmedetomidine.
