The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

Objective To explore the hierarchical chain management model of type 2 diabetes and determine its evaluation.Method Based on the hierarchical chain management of the three community health service institutions and Dahua hospital in Shanghai Xuhui district,215 cases of type 2 diabetes had been involved in the study.Results Compared with the baseline before management,lasting blood glucose (FBG),2 h postprandial glucose (2hPBG),glycosylated hemoglobin (HbA1c),low density lipoprotein cholesterol (LDL-C),systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the diabetes after 12 months' management declined [(8.50 ±2.81) mmol/L,(11.09 ±4.01) mmol/L,(8.56 ±2.41)% ,(3.31 ± 1.06) mmol/L,(139.06 ±20.68) mm Hg (1 mm Hg = 0.133 kPa),(78.20 ± 12.11) mm Hg vs.(7.41 ±2.04) mmol/L,(9.03 ±2.46) mmol/L,(7.34 ± 1.59)% ,(3.00 ± 1.06) mmol/L,(135.48 ± 17.82) mm Hg,(77.27 ±11.83) mm Hg],and the differences were statistically significant(P＜0.01 );control rate of FBG,2hPBG,HbA1c,LDLC,SBP,DBP had improved significantly [19.5% (42/215),20.9% (45/215),24.7%(53/215),20.0%(43/215),27.4%(59/215),30.2%(65/215) vs.50.7%(109/215),53.0% (114/215),54.0%(ll6/215),42.3%(91/215),47.0%(101/215),45.6%(98/215)](P＜0.01).Conclusion Primary and secondary-care hospital based hierarchical chain management model is valid and can be implemented for type 2 diabetes.

To investigate the therapeutic effect and molecular mechanism of the main flavonoid components of Silybum marianum (S. marianum) on nonalcoholic fatty liver disease (NAFLD), we identified nine flavonoids in S. marianum through TCMSP, PubChem database and corresponding literatures. The potential therapeutic targets of NAFLD were predicted by SwissTargetPrediction, GeneCards and Venny 2.1.0 platform, while the protein-protein interaction (PPI) network of potential targets was analyzed using String platform and Cytoscape software. Then GO and KEGG pathway enrichment analysis were performed using David 6.8 database, followed by molecular docking verification using AutoDock software. In vitro, components with higher degree value in the "components-targets-pathway" network were chosen for further analysis. L02 cells were used to establish lipid accumulation model and treated with different components. Furthermore, the effects of four pure active compounds from S. marianum on lipid accumulation in hepatocytes were analyzed by oil red O staining. The results showed that the main nine flavonoids extracted from S. marianum contained 24 potential NAFLD targets. Several critical pathways closely related to NAFLD process were identified by GO and KEGG enrichment analysis, including phosphatidylinositol 3-kinase-protein kinase B (PI3K-Akt) pathway, type 2 diabetes pathway, tumor necrosis factor (TNF) pathway and insulin resistance pathway. The results of molecular docking further indicated that the core components displayed strong binding abilities with key targets respectively, and silandrin showed better binding activity as compared to other components. The results obtained from L02 cells showed that the lipid accumulation was reduced by treatment with isosilybin A, isosilybin B, silydianin and silychristin, while the activity of isosilybin B was better than that of isosilybin A. Taken together, we concluded that the main flavone components of S. marianum could improve lipid accumulation through multiple signaling pathway in hepatocytes, and this could be a potential new strategy for the treatment of NAFLD.

Objective To explore the hierarchical chain management model in blood glucose control and its influence factors in patients with diabetes mellitus.Methods Health management database of diabetic patients was established in 2007 and managed by hierarchical chain management.The number of the patients reached to 1010 till 2011.The blood glucose control of diabetic patients was analyzed and its influence factors were analyzed by multivariate unconditional Logistic regression method.Results The concentration of glycosylated hemoglobin( HbA1c ) of 1010 patients with type 2 diabetes was (8.21 ±:2.70)％.Four hundred and eighty-seven cases (48.22％) reached the blood glucose standard,303 cases (30.00％)reached the blood pressure standard,245 cases (24.26％) reached the blood lipids standard,and 76 cases (7.52％) reached all three standards.Multivariate analysis showed that occupation (OR =2.521,95％ CI:1.871 - 3.397),education level (OR =1.890,95％ CI:1.642 - 2.174),disease course (OR =1.035,95％CI:1.016 -1.055),systolic pressure (OR =1.016,95％ CI:1.007 -1.025) and triglyceride (OR =1.204,95％CI:1.063 - 1.365) were the risk factors of blood glucose control (P ＜0.01).Conclusions Hierarchical chain management model is helpful for the blood glucose control in patients with type 2 diabetes.The comprehensive control and treatment of type 2 diabetes should be taken combined with related risk factors,such as blood pressure,blood lipids and diabetes disease course.

OBJECTIVETo observe the effect of Yugan Granule (YGG) in treating patients of chronic hepatitis B infected with basic core promoter (BCP) mutant HBV.

METHODSBCP mutation was detected by microwell liquid hybridization combined with enzyme linked immunosorbent assay (ELISA) and 46 patients were confirmed to be the mutant positive (Group A), and 69 the mutant negative (Group B). All patients were treated by YGG and the clinical symptoms and laboratory parameters before and after treatment were observed.

RESULTSThe scores of symptoms and serum levels of alanine transaminase (ALT) and total bilirubin (TBil) were decreased markedly in both groups after treatment. The HBeAg negative conversion rate in Group A was 60%, obviously higher than that in Group B (30%, P < 0.05), while HBV-DNA negative conversion rate between the two groups had the insignificant difference. The overall efficacy was similar in the two groups.

CONCLUSIONYGG could remarkably alleviate the symptoms, reduce serum levels of ALT and TBil, and showed the effect of anti-HBV with the same efficacy both to BCP mutant and wild strain HBV infected patients.

Objective To study the effects of Guhong injection on the expression of vascular endothelial growth factor (VEGF) in the cortex 14 days after cerebral ischemia-reperfusion. Methods 30 male Sprague-Dawley rats were divided into sham group (n=6), ischemia group (n=6), aceglutamide injection group (n=6), Honghua injection group (n=6) and Guhong injection group (n=6). The middle cerebral arteries of all the rats were occluded for 2 hours and reperfusion, except the sham group. Drugs were administered once a day 24 hours after reperfusion. The expression of VEGF in cortex was detected with enzyme-linked immunosorbent assay (ELISA) 14 days after reperfusion. Results The expression of VEGF decreased in the ischemia group compared with the sham group (P<0.001), and it increased both in the aceglutamide and Guhong injection groups compared with the ischemia group (P<0.05). Conclusion Guhong injection can significantly increase the expression of VEGF in the cortex 14 days after ischemia-reperfusion, which may be one of the ways for neuro-protection.

Objective To find out the status of drinking-water-borne endemic fluorosis and the effect of preventive measures in Hebei Province,so as to provide a basis to prevent and cure fluorosis.Methods One affected county (city,district) with drinking-water-borne endemic fluorosis was sampled in every city and 10 water improvement projects were investigated in that county.Three villages were taken out in every county.The operating state of the projects,the water fluoride content,and the dental fluorosis of children aged 8-12 and skeletal fluorosis of adults were investigated in these villages.Results A total of 93 projects were investigated,among which 94.6％(88/93) were operating properly and the qualified rate(fluoride content ≤ 1.2 mg/L) of the projects was 54.84％(51/93).Among the 9 large projects,the water fluoride content of 7 projects exceeded 1.2 mg/L.A total of 23 villages with water improvement projects were investigated and only 43.4％ (10/23) of them water fluoride content were lower than 1.2 mg/L.The dental fluorosis rate,the dental fluorosis index and the rate of skeletal fluorosis were 33.2％ (532/1601),0.74 and 5.7％ (66/1155),respectively.In the 7 villages without water improvement projects,2 of them exceeded 2.0 mg/L,but lower than and equal to 4.0 mg/L of water fluorosis and 5 of them were normal(＜ 1.2 mg/L).The dental fluorosis rate,the dental fluorosis index and the rate of skeletal fluorosis were 33.4％ (111/332),0.72 and 2.9％ (10/350),respectively.Conclutions The qualified rate of water improvement projects of fluoride content ≤ 1.2 mg/L is low and the endemic fluorosis is still comparatively serious in Hebei Province.The progress of water improvement projects in the areas with endemic fluorosis should be accelerated and the quality of water improvement projects should be increased.
