OBJECTIVETo investigate the intervention effect and mechanism of compound Ginkgo biloba (CGB) preparations on nonalcoholic fatty liver disease (NAFLD).
METHODThe C57BL/6 mouse NAFLD model was induced with high fat diets. Since the 2nd week after modeling, the mice were orally administered with 600 and 200 mg x kg(-1) x d(-1) CGB for eight weeks. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), cholesterol (CHOL) and LPS in serum, as well as pathological changes and expression of tumor necrosis factor-alpha (TNF-alpha) in hepatic tissues were observed. Changes in intestinal tight junction proteins ZO-1, Occludin, Claudin-1 in intestinal tissues were determined under microscopy.
RESULTCompared with the normal group, the model group showed obvious fatty degeneration in rat livers, with notable increase in TNF-alpha expression (P < 0.01), significant increases in ALT, AST, TG, CHOL and LPS in serum (P < 0.01, P < 0.05), injury in intestinal tight junction proteins, and remarkable declines in ZO-1, Occludin and Claudin-1 (P < 0.01). Compared with the model group, CGB high and low dose groups showed obvious relieves in fatty degeneration in rat livers and injury in intestinal tight junction proteins, significant reductions in TNF-alpha expression (P < 0.01, P < 0.05) and AST, TG, CHOL and LPS in serum (P < 0.01, P < 0.05) and remarkable increases in ZO-1 and Occludin expressions (P < 0.05).
CONCLUSIONCGB can protect intestinal tight junction proteins, reduce intestinal leakage, relieve fatty degeneration and inflammations in livers and prevent NAFLD occurrence and development.

Objective To describe the pathogenic and serological test results of the plague in China from 2001 to 2009, and human and animal plague distribution. Methods Through access to information of the plague surveillance report in China from 2002 to 2010, national plague pathogenic and serological test results and the epidemic situation were analyzed from 2001 to 2009. Results From 2001 to 2009, 2966 strains of Yersinia pestis were isolated in the seven provinces which were Guizhou, Guangxi, Yunnan, Qinghai, Tibet, Gansu and Inner Mongolia. Of these, 1 138 000 animals were detected by bacteriological method, 1998 strains of Yersinia pestis were isolated;379 227 groups of intermediary animals were detected, 927 strains of Yersinia pestis were isolated;41 strains of Yersinia pestis were isolated from human body. Animal serums of 1 169 702 were detected by indirect hemagglutination assay(IHA), of these 3177 animal serums were positive, 168 human serums were positive;53 323 animal samples were detected by reverse indirect hemagglutination assay(RIHA), of these 500 were positive. There were outbreak or epidemic of plague in 9 types of plague foci, 2925 strains of Yersinia pestis were isolated. Two animals and 6 fleas were judged as new reservoir and new vector. There were 23 counties of 6 provinces were judged as plague new natural foci counties. Conclusions The plague epidemic in China is still serious between 2001 and 2009. There are nine types of foci in the active state.

AIM To investigate the exact subtype of ryanodine receptor (RyR) in pulmonary artery smooth muscle cell(PASMC) and the change of RyR expression from pulmonary hypertensive (PAH) rats. METHODS Rats pre treated with a single intraperitoneal injection of monocrotaline (MCT, 60 mg?kg -1 ) were used to produce PAH animal model and killed 21 d later. The subtype expression of RyR and the change of their mRNA were measured by RT PCR; protein expression of RyR was measured by Western blot in PASMC. RESULTS The PASMC of rats only expressed type ⅡRyR (RyR2). RT PCR showed the RyR2 mRNA concentration of PAH group was higher than that of control; Western blot demonstrated that the RyR2 protein level in PAH group was increased to (170 23?45 34)%. CONCLUSION PASMC only expressed RyR2 subtype and the increment of RyR2 expression may contribute to the pathological mechanism of PAH formation.
