RESUMO

Objective To investigate the intervention effect of Xuanfuhua decoction on mice with nonalcoholic steatohepatitis (NASH) induced by high-fat, high-fructose, and high-cholesterol diet. Methods A total of 32 male C57/BL6J mice were randomly divided into normal group, model group, Xuanfuhua decoction group, and obeticholic acid group, with 8 mice in each group. Since week 24 of modeling using high-fat, high-fructose, and high-cholesterol diet, each group was given the corresponding drug for intervention at a dose of 14.19 g/kg by gavage for the Xuanfuhua decoction group and 10 mg/kg by gavage for the obeticholic acid group and a volume of 20 mL/kg for gavage, once a day for 6 consecutive weeks. HE staining, oil red O staining, Sirius Red staining, and Masson staining were used to observe the pathological changes, lipid deposition, and collagen deposition of liver tissue; related kits were used to measure the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and glucose, as well as the content of TG and hydroxyproline (Hyp) in liver tissue; quantitative real-time PCR was used to measure the expression of genes associated with lipid metabolism, inflammation, and fibrosis in liver tissue; immunohistochemical staining was used to observe the positive expression of F4/80 and α-SMA in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results Compared with the normal group, the model group had significant increases in body weight, liver wet weight, and serum levels of AST, ALT, TC, TG, LDL-C and glucose (all P < 0.01). HE staining showed hepatocyte steatosis, a large number of fat vacuoles, hepatocyte ballooning degeneration, and inflammatory cell infiltration in liver tissue of the mice in the model group, and the model group had a significant increase in NAFLD activity score (NAS) compared with the normal group ( P < 0.01). Oil red O staining showed the deposition of a large number of red lipid droplets with different sizes in hepatocytes of the mice in the model group, and compared with the normal group, the model group had significant increases in the area percentage of oil red O staining and the content of TG in the liver ( P < 0.01). Sirius Red staining and Masson staining showed significant collagen fiber hyperplasia in the perisinusoidal area, the central vein, and the portal area in the model group, and the model group had a significant increase in the content of Hyp in liver tissue compared with the normal group ( P < 0.05). Compared with the model group, the Xuanfuhua decoction group had significant reductions in the serum levels of AST, ALT, TC, TG, LDL-C, and glucose (all P < 0.05), significant improvements in hepatic steatosis, inflammatory infiltration, lipid droplet deposition, and collagen fiber hyperplasia, and significant reductions in NAS score, area percentage of oil red O staining, and content of TG and Hyp in the liver (all P < 0.05). Compared with the normal group, the model group had significant increases in the mRNA expression levels of lipid metabolism-related genes (SREBP-1c, FASN, SCD-1, PPAR-γ, and CD36), inflammation-related genes (F4/80, TNF-α, CCL2, and CD11b), and the fibrosis-related gene α-SMA (all P < 0.05), and immunohistochemical staining showed significant increases in the positive expression of F4/80 and α-SMA ( P < 0.01). Compared with the model group, the Xuanfuhua decoction group had significant reductions in the mRNA expression levels of SREBP-1c, FASN, SCD-1, PPAR-γ, CD36, F4/80, TNF-α, CCL2, CD11b, and α-SMA in liver tissue (all P < 0.05), and immunohistochemical staining showed significant reductions in the positive expression of F4/80 and α-SMA ( P < 0.01). Conclusion Xuanfuhua decoction has a good intervention effect on mice with NASH induced by high fat, high fructose, and high-cholesterol diet and can significantly inhibit hepatic lipid deposition, inflammatory response, and liver fibrosis.

RESUMO

Objective@#To understand the sanitary condition of rural school toilets in Laibin City, and to provide scientific basis for the government and education departments to improve the sanitary condition of rural school toilets and to rebuild and build new harmless sanitary toilets.@*Methods@#The sanitary condition of toilets and feces treatment of the rural areas of 6 counties of Laibin City were thoroughly investigated through file review, on-site inspection and interviews.@*Results@#There were 36 schools without toilets, all of which were primary schools. Those schools distributed in Jinxiu County (31), accounting for 35.63% in its primary schools(31/87). Among the 651 schools with toilets, there were 1 559 sanitary toilets and 90 unsanitary toilets (all distributed in primary schools). and the percentage of unsanitary toilets in primary schools was that Jinxiu County 44.64% and Heshan City 31.25%. The proportion of sanitary toilets in teaching buildings, offices or dormitory buildings in primary schools, middle schools and nine-year schools was 77.36%, 94.20% and 30.95%, respectively. Hierarchical analysis found that outdoor toilets accounted for the largest proportion of middle schools in Xiangzhou County (72.46%), followed by nine-year schools in Xingbin District (71.79%). Among sanitary toilets, the proportion of harmless sanitary toilets was 95.51%, which was 100% in middle schools and nine-year schools, and 94.30% in primary schools. Four of the six counties (cities and districts) accounted for 100%, and the proportion of primary schools of Xingbin District was lowest, which accounted for 89.79%.@*Conclusion@#At present, the sanitary condition of toilets in rural schools in Laibin City has been obviously improved, but there are still many schools lack of toilets or sanitary toilets, in some counties (cities, districts), especially in primary schools. Quality of toilet management should be improved while strengthening the construction of harmless sanitary toilets in schools.

RESUMO

Objective To observe the clinical efficacy of auricular point sticking with magnetic bead in treating insomnia in hepatocirrhosis patients. Method Ninety patients with hepatocirrhosis complicated with insomnia were randomized into a treatment group and a control group, 45 in each group. The treatment group was intervened by auricular point sticking with magnetic bead, while the control group was by auricular point sticking with medical adhesive tape. After successive 2-week treatments, the Insomnia Severity Index (ISI) and the Evaluation Criteria of Therapeutic Efficacy for Mental Disorders were observed for evaluating the treatment result. Result The ISI was significantly improved in the treatment group after intervention (P<0.05), and the improvement was significantly different from that in the control group (P<0.05). The total effective rate was 86.7% in the treatment group versus 60.0% in the control group, and the difference was statistically significant (P<0.01). Conclusion Auricular point sticking with magnetic bead is easy-to-operate and can produce a satisfactory efficacy in treating insomnia of hepatocirrhosis patients.
