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 improve the comprehensive understanding and treatment level of the disease by analyzing the clinical characteristics of rheumatoid arthritis (RA) caused by pauciarticular arthritis.Methods The method was retrospective analysis and summary of clinical and laboratory data of 198 cases of patients with RA,in which 98 cases of pauciarticular arthritis belonged to the observation group and 100 cases of polyarticular arthritis belonged to the control group.Results Male patients in observation group were obviously more than those in the control group (t =2.456,P =0.015).Courses of disease was obviously shorter than those in the control group (t =-2.450,P =0.018).The number of involved joints was obviously less than those in the control group (t =-6.316,P <0.001).The incidence of morning.stiffness was significantly less than those in the control group (t =-3.884,P < 0.001).Rating scores of disease activity score 28 were significantly lower than those in the control group (t =-8.694,P < 0.001).And positive rate of anti-cyslic citrullinated peptide antibody is significantly higher than those in the control group (t =-2.299,P =0.022).Thyrotrophin levels were significantly higher than those in the control group (t =3.809,P < 0.001).There was no significant differences in age,erythrocyte sedimentation rate and C reactive protein,immunoglobulin and complement level,free triiodothyronine,free thyroxine,blood lipids,blood system and kidney involvement between the two groups (all P > 0.05).Conclusions The conclusion turns out to be that there are no typical clinical manifestations showing that rheumatoid arthrifts is caused by pauciarticular arthritis.Maybe it is the early performance of disease.It is worth attention that concurrent subclinical hypothyroidism turns out to be more.

Most chemical medicines have polymorphs. The difference of medicine polymorphs in physicochemical properties directly affects the stability, efficacy, and safety of solid medicine products. Polymorphs is incomparably important to pharmaceutical chemistry, manufacturing, and control. Meantime polymorphs is a key factor for the quality of high-end drug and formulations. Polymorph prediction technology can effectively guide screening of trial experiments, and reduce the risk of missing stable crystal form in the traditional experiment. Polymorph prediction technology was firstly based on theoretical calculations such as quantum mechanics and computational chemistry, and then was developed by the key technology of machine learning using the artificial intelligence. Nowadays, the popular trend is to combine the advantages of theoretical calculation and machine learning to jointly predict crystal structure. Recently, predicting medicine polymorphs has still been a challenging problem. It is expected to learn from and integrate existing technologies to predict medicine polymorphs more accurately and efficiently.

Objective To investigate the clinical value of ultrasonic diagnosis for neonatal annular pancreas,analyze the reasons of missed diagnosis and misdiagnosis,and improve diagnostic accuracy of ultrasonography for this disease.Methods Clinical data of 98 newborns with annular pancreas confirmed by gastrointestinal contrast and surgery were analyzed retrospectively.Preoperative ultrasonogram were compared with the result of gastrointestinal contrast and surgery.Ultrasound images failed to be correctly dignosed were further studied to summarize diagnostic points for this disease.Results Among the 98 cases, 75 were correctly diagnosed by ultrasound with a diagnostic accordance rate of 76.5%,1 8 were missed diagnosed and 5 were misdiagnosed with a total misdiagnosis rate of 23.5%.Ten cases associated with other congenital gastrointestinal tract anomalies were missed diagnosed due to ignoring scanning pancreas.Five cases were missed diagnosed due to obvious intestinal cavity flatulence.Three cases were missed diagnosed due to lack of awareness of the disease.Five cases were misdiagnosed for duodenal stenosis or duodenal atresia.Conclusions Ultrasound has important diagnostic value for neonatal annular pancreas,providing the dignostic evidences for clinical treatment.Thus it can be used as the preferred auxiliary examination of the disease.Since annular pancreas is often accompanied by other gastrointestinal malformations and can be interfered by abdominal gas,missed diagnosis and misdiagnosis occurred easily.To improve the accuracy of ultrasonic diagnosis,all causes of neonatal gastrointestinal tract obstructions should be considered during the examination.

Objective To investigate the clinical outcome and treatment of portal vein thrombosis (PVT) following partial splenic embolization (PSE).Methods From April 2006 to April 2010,105patients with hypersplenism caused by cirrhotic portal hypertension were treated with PSE.Contrastenhanced abdominal computed tomography or magnetic resonance imaging was performed routinely in 60patients before PSE and 1 -3 months after PSE.PVT was detected in 10 patients on images after the procedures.After PVT was diagnosed,4 patients received anticoagulant therapy immediately,and the other 6 patients did not receive therapy.Clinical data of these 10 PVT patients were analyzed retrospectively.Results 3 of 4 patients who received anticoagulant therapy had complete or partial resolution of the thrombus,and one developed mild ascites without thrombosis progression.Of the 6 patients who did not receive anticoagulant therapy,follow-up studies (6- 48 months,mean 16.9 months) demonstrated partial clot calcification in one,thrombosis progression in 5.Among those 5 patients with thrombosis progression,two experienced hematemesis due to variceal rupture and underwent transjugular intrahepatic portosystemic shunt,2 developed cavernous transformation,extensive collateral circulation,ascites and variceal progression,and one had variceal progression with melena during the follow-up period.Conclusions PVT is a severe complication of PSE.Early diagnosis and prompt anticoagulant therapy is effective in preventing PVT.
