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 explore the impact of nuclear factor-kappa B (NF-κB) in patients with left-to-right shunt congenital heart disease (CHD) combining pulmonary arterial hypertension (PAH) and its clinical signiifcance. Methods: A total of 78 relevant patients were enrolled in this study. According to mean pulmonary artery pressure (mPAP) measured during operation, the patients were divided into 4 groups: Non-PAH group, the patients with mPAP≤25 mmHg,n=20, Mild PAH group, 25 mmHg mPAP≤35 mmHg,n=21, Moderate PAH group, 35 mmHg45 mmHg,n=23. 2 mL pulmonary artery blood was taken from each patient and plasma level of NF-κB was measured by ELISA to study the relationship between NF-κB and mPAP. Results: Pulmonary arterial plasma levels of NF-κB were increased accordingly as in Non-PAH group was (180.59 ± 10.16) ng/L, in Mild PAH group was (572.83 ± 34.80) ng/L, in Moderate PAH group was (980.85 ± 24.95) ng/L and in Severe PAH group was (1 253.4 ±130.8) ng/L, allP<0.01; NF-κB level was positively related to mPAP (r=0.856,P<0.01). Conclusion: Plasma level of NF-κB was involved in the pathological physiology process of left-to-right shunt CHD combining PAH, it couldbe used as one of the references for distinguishing the severity of PAH and for monitoring the dynamic changes of PAH in relevant patients.

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 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.

The postpartum depression outcome and the effect of psychological intervention were studied in order to reduce the occurrence and development of the postpartum depression. A survey of 4000 women within 4-6 weeks postpartum in 80 communities in Shenzhen, China was performed using random cluster sampling method. By employing Edinburgh Postnatal Depression Scale (EPDS) as a screening tool, the positive women (defined as EPDS ≥10) were randomly divided into intervention group and control group at a ratio of 1:2. The women in the intervention group were treated by means of mailing postpartum depression prevention and treatment knowledge manual, face-to-face counseling, and telephone psychological counseling interventions aiming at individual risk factors, while those in the control group were treated with conventional methods. EPDS scores were assessed in these two groups again at 6th month postpartum. Totally, 3907 valid questionnaires were obtained. All the 771 positive women were divided into two groups: 257 in the intervention group, and 514 in the control group. At 6th month postpartum, the EPDS scores in the intervention group were decreased significantly, from baseline stage (12.84±3.02) to end stage (3.05±2.93), while EPDS scores in the control group were reduced from 12.44±2.78 to 6.94±4.02. There were significant differences in the EPDS scores at end stage between the two groups (t=13.059, P<0.001). Psychological intervention can reduce postpartum depression, with better maternal compliance. It is feasible and necessary to establish postpartum depression screening and psychological intervention model in community-hospital and include the postpartum depression screening, intervention, and follow-up into the conventional healthcare.
