Objective To investigate the effect of American cockroach extract on the expression of NF-κB andα-SMA in experi-mental liver fibrosis tissue,and to observe its antifibrotic efficacy.Methods The rat model of hepatic fibrosis was duplicated by car-bon tetrachloride and simultaneously given with American cockoach extract 0.5 g/kg by lavage.The level of serum alanine amin-otransferase enzyme (ALT),aspartate aminotransferase (AST)and albumin (Alb)were determined.The expression levels of NF-κB and a-SMA in liver tissue were determined by the immunohistochemical method and the liver histological changes were observed by light microscopy for conducting the grading of inflammatory activity and the fibrosis classification.Results American cockroach extract could reduce serum ALT,AST and liver tissue NF-κB andα-SMA levels.The serum Alb level had significant difference a-mong the APA group,Pseudo-ginseng Danshen group and the model group.The degeneration and necrosis of liver cells and the fi-brosis degree after medication were significantly reduced.Conclusion The American cockroach extract has certain anti-fibrosis effect,its mechanism may be related with the inhibition of expression of NF-κB andα-SMA.

Impacto del consumo nocivo de alcohol en accidentes y enfermedades crónicas en México / Impact of harmful consumption of alcohol in accident-related mortality and chronic diseasses in Mexico

Objetivo. Analizar el consumo de alcohol, su relación con accidentes de tránsito y su impacto en enfermedades crónicas. Material y métodos. Usando encuestas nacionales de salud, registros de colisiones, lesionados y muertes, así como encuestas económicas, se estimaron indicadores de prevalencia, mortalidad y consumo. Resultados. Entre 2000 y 2012, la prevalencia de consumo de alcohol en adolescentes se mantuvo estable con un incremento importante en adultos. La tasa de colisiones de tránsito con presencia de alcohol fue de 0.36 y 0.58 en adolescentes y adultos, respectivamente. De la población con lesiones de tránsito, 8.4% estaba bajo efectos del alcohol al momento de lesionarse. La mortalidad por dos enfermedades atribuibles al alcohol se ha mantenido en alrededor de 18 000 fallecimientos anuales. Conclusiones. El abuso en el consumo alcohol implica graves daños a la salud. El incremento de impuestos al alcohol, junto con otras medidas, reduciría el consumo nocivo y la mortalidad asociada.

Objective. To analyze alcohol consumption, and its impact on road traffic-related mortality and chronic diseases. Materials and methods. Through the analysis of national health surveys, registry of traffic collisions, mortality records and economic surveys, we estimated prevalence, mortality and consumption indicators. Results. Between 2000 and 2012, alcohol consumption in adolescents remained stable, with a significant increase among adults. Traffic collision rates related with alcohol were 0.36 and 0.58 among adolescents and adults, respectively; 8.4% of the population who suffered traffic injuries was under alcohol effects when the accident occurred.

The effect of the balance between cytokines in the serum of hepatic fibrosis rats on the expression of β-catenin in their livers / 中华传染病杂志

Objective To investigate the effect of the balance between helper T lymphocyte (Th) 1 cytokines and Th2 cytokines in the serum of hepatic fibrosis rats induced by CCl4 on the expression of β-catenin in their livers. Methods Seventy-five rats were divided into control group,treatment group and model group. Hepatic fibrosis models were built by subcutaneous injection of CCl4in male Wistar rats, then rats in treatment group were treated with pentoxifylline(PTX) by intragastric administration. The model rats without PTX treatment served as treatment control. The serum levels of Th1 cytokines(interferon-γ, IFN-γ; tumor necrosis factor-α, TNF-α), Th2 cytokines (interleukin-4,IL-4;interleukin-6,IL-6) and type Ⅳ collagen were measured by enzyme-linked immunosorbent assay (ELISA). The expression and distribution of β-catenin in liver tissue and the percentage of area of type Ⅳ collagen accounted in the liver were analyzed by immunohistochemical analyses. The changes in serum cytokines were depicted by using One-way ANOVA, and the correlation between β-catenin expression and cytokines levels or hepatic fibrosis development was elucidated by Bivariate.Results The serum levels of Th2 cytokines in model group were significantly higher than those in treatment group, and even higher than those in control group (F=71. 260,91. 732, all P＜0.05).However, the levels of Th1 cytokines in model group were significantly lower than in treatment group while even lower than those in control group(F= 50. 420,10. 625, all P＜0.05). Serum cytokines came out to be Th2 polarized. Meanwhile, the percentage of type Ⅳ collagen area accounted in the liver,which was corresponding to the degree of liver fibrosis, was lower in the treatment group than the model group and even lower in control group (F=3 000,both P<0.05). β-catenin expression in the liver of model group was stronger than that in the treatment group, and even stronger than that in normal group (F=92. 030, both P＜0. 05). According to β-catenin immunohistochemical analyses based on patho-photos, livers from the model group showed dark color in both cell cytoplasm and nucleus, while the liver from the treatment group only showed weak color in cytoplasm and no straining color in nucleus and the liver from normal group showed colors neither in cytoplasm nor in the nucleus.The expression of β-eatenin had a positive correlation with either the level of Th2 cytokines in serum of rats (r=0. 560,P＜0.01) or the percentage of area of type Ⅳ collagen accounted in the liver of rats (r=0. 757, P＜0. 01). Conclusions Th2 polarization in serum cytokines can aggravate the development of liver fibrosis by inducing the expression of β-catenin, which in the livers of rats is a reflection of the degree of the liver fibrosis.
