Objective To study the gene expression of Wnt signal transduction pathway in experimental liver fibrosis and to investigate its role in liver fibrosis. Methods Liver fibrosis model was induced with carbon tetrachloride in 8 SD rats. Another 8 healthy rats were served as control. The gene expression in liver tissues of models and controls were examined using real time PCR array. The differential gene expression was identified as either up- or down-regulated 2-fold. The expressions of smooth muscle actin (SMA), Wnt4, Frizzled2 and β-catenin in the tissues were examined by immunohistochemistry and Western blot. Results The examination confirmed that 36 genes were differentially expressed, including 25 genes up-regulated and 11 genes down-regulated. Compared with the controls, the expressions of Wnt4, Wnt5 a and W nt11 were up-regulated more than 13.9-, 16.5-and 2.17-fold respectively, while the expressions of Wntl and Wnt3 were down-regulated more than 2.32- and 2.15-fold respectively in fibrotic liver. Immunohistochemistry and Western blot showed that the expressions of SMA, Wnt4 and Frizzled2 in fibrotic liver were remarkably higher than those in normal controls. While the level of phosphorylated β-catenin was decreased. Conclusion Both canonical and noncanonical Wnt signal transduction pathway may involve in the mechanism of liver fibrogenesis.

Objective To evaluate the implementation of the national essential medicine system in Shaanxi Province.Methods Using a standardized methodology (2008 Edition) developed by the World Health Organization(WHO) and Health Action International(HAD,data on the prices and availability of 38 essential medicines were collected from 120 primary,secondary and tertiary public hospitals in ten cities of Shaanxi Province from March to May 2012.Results The availability of essential medicines is generally low at public hospitals in Shaanxi province,as the average availability of originator brands is but 5.9％,and that of generics of the lowest prices is but 23.9％,while this availability at tertiary hospitals is higher than hospitals of lower levels.The procurement prices of originator drugs within essential medicines are distinctly higher than the international reference prices for the originator brands,and slightly higher for the lowest priced generics.The procurement prices at primary care hospitals are slightly lower than that of other hospitals.Retail prices of essential medicine are not significantly different among regions of different income levels.Affordability of originator brands is poor,while that of their generic equivalents is good.Conclusion The government is recommended to adjust the national essential medicine list,expand the variety of essential medicine moderately,improve the medicine pricing mechanism,and deepen public hospitals reform.

Objective To know the levels of antibodies against influenza A virus subtypes H1 and H3 of population in Shanghai during 2009, and the detection of antibodies against avian influenza virus subtypes H5 and H9 in population which contacts with avian. Methods The serological survey of the antibodies against influenza A viruses subtypes H1, H3, H5 and H9 in 356 close contacts with avian (professional population) and 332 general subjects (general population) at various age groups were carried out using hemagglutinin inhibit (HI) test. Results The positive rates of antibodies against influenza virus A/Brisbane/59/2007 (H1N1) in general population and professional population were 82.8% (275/332) and 73.9% (263/356), respectively; those of A/Brisbane/10/2007 (H3N2)were 50.6% (168/332) and 54.8% (195/356), respectively. The positive rate of antibodies against influenza virus A/Brisbane/59/2007 (H1N1 )was significantly higher than that of influenza A viruses subtype H3, which was consistent with etiological survey of influenza virus in Shanghai during 2008.The positive rates of antibodies against influenza A virus subtype H5 in professional population and general population were 4.2% (15/356) and 0.3% (1/332), respectively; those of influenza A virus subtype H9 were 34.6% (123/356) and 2.4% (8/332), respectively. The positive rates of antibodies against influenza virus A/Brisbane/59/2007 (H1N1 ) and A/Brisbane/10/2007 (H3N2) in age groups of 6 months-5 years and ≥60 years were lower than other age groups. Conclusions The immune protective response against seasonal influenza A subtype H1 and H3 of population in Shanghai is high,while those of children and the elders were low. The levels of antibodies against influenza A viruses subtype H5 and H9 in professinal population present obviously ascending trend, which indicates that the etiological and serological survey of influenza virus in this population should be enhanced.

Epithelial membrane protein 3 (EMP3) is a trans-membrane signaling molecule with important roles in the regulation of apoptosis, differentiation and invasion of cancer cells, but the detailed is largely still unknown. We analyzed the mRNA levels and methylation statuses of EMP3 in 63 primary breast carcinomas and assessed their correlations with clinicopathologic variables. The expression of EMP3 mRNA in primary breast carcinomas was significantly higher than the expression of 20 normal breast tissues (p<10(-7)). EMP3 overexpression in breast carcinomas was significantly related to histological grade III (p=3.9X10(-7)), lymph node metastasis (p= 0.003), and strong Her-2 expression (p=3.3X10(-6)). Hypermethylation frequencies of EMP3 were detected in 36.5% of breast carcinomas by methylation-specific polymerase chain reaction. However, no significant correlations were found between methylation status of EMP3 and mRNA expression levels as well as other clinical parameters. In conclusion, EMP3 may be a novel marker of tumor aggressiveness. Overexpression of EMP3 in primary breast carcinoma is not associated with DNA methylation.

Isatis indigotica Fort. (Ban-Lan-Gen) is an herbal medicine prescribed for influenza treatment. However, its active components and mode of action remain mostly unknown. In the present study, erucic acid was isolated from Isatis indigotica Fort., and subsequently its underlying mechanism against influenza A virus (IAV) infection was investigated in vitro and in vivo. Our results demonstrated that erucic acid exhibited broad-spectrum antiviral activity against IAV resulting from reduction of viral polymerase transcription activity. Erucic acid was found to exert inhibitory effects on IAV or viral (v) RNA-induced pro-inflam-matory mediators as well as interferons (IFNs). The molecular mechanism by which erucic acid with antiviral and anti-inflammatory properties was attributed to inactivation of NF-kB and p38 MAPK signaling. Furthermore, the NF-kB and p38 MAPK inhibitory effect of erucic acid led to diminishing the transcriptional activity of interferon-stimulated gene factor 3 (ISGF-3), and thereby reducing IAV-triggered pro-inflammatory response amplification in IFN-β-sensitized cells. Additionally, IAV- or vRNA-triggered apoptosis of alveolar epithelial A549 cells was prevented by erucic acid. In vivo, erucic acid administration consistently displayed decreased lung viral load and viral antigens expression. Meanwhile, erucic acid markedly reduced CD8+cytotoxic T lymphocyte (CTL) recruitment, pro-apoptotic signaling, hyperactivity of multiple signaling pathways, and exacerbated immune inflammation in the lung, which resulted in decreased lung injury and mortality in mice with a mouse-adapted A/FM/1/47-MA(H1N1) strain infection. Our findings provided a mechanistic basis for the action of erucic acid against IAV-mediated inflammation and injury, suggesting that erucic acid may have a therapeutic potential in the treatment of influenza.
