Objective To study the effect of pravastatin on the patients with chronic renal failure(CRF)and normal blood lipid. Methods 48 cases of CRF patients with normal blood lipid were randomly divided into two groups. 26 patients of group 1 were given pravastatin besides basic treatment. 22 patients of group 2 were only given basic treatment. The treatment was consecutive for one year. Blood lipid, serum creatinine, clearance rate of serum creatinine(Ccr), urinary retinol-binding protein(RBP) and protein amount in urine were tested respectively before treatment and one month, six months and one year after the treatment. Results Compared with the patients of group 2, blood lipid, urinary RBP and total urinary proteins and serum creatinne decreased, and Ccr increased in the patients of group 1. Conclusion Pravastatin can postpone the renal dysfunction of the CRF patients with nomal blood lipid.

VP1, a capsid protein of swine vesicular disease virus, was cloned from the SVDV HK/70 strain and inserted into retroviral vector pBABE puro, and expressed in PK15 cells by an retroviral expression system. The ability of the VP1 protein to induce an immune response was then evaluated in guinea pigs. Western blot and ELISA results indicated that the VP1 protein can be recognized by SVDV positive serum, Furthermore,anti-SVDV specific antibodies and lymphocyte proliferation were elicited and increased by VP1 protein after vaccination. These results encourage further work towards the development of a vaccine against SVDV infection.

To gain a better understanding of the genetic diversity and evolution of PRRSV in the Ningxia Hui Nationality Autonomous Region (Ningxia) of China, the nsp2 genes from a series of PRRSV strains collected from the region in 2007 were partially sequenced. These sequences were then analyzed along with the classical strain (ch-la) and two other epidemic strains SD (3) and SD2006. Comparison of the nucleotide sequence with ch-la indicated that nsp2 genes of seventeen Ningxia isolates (NX strain) have deletions of 87 nucleotides. Sequence analysis indicated that homology between the Ningxia strain and ch-la was 60.3%-79.9% in the nucleotide sequence, and homology between the NX strains and SD strains was 80.3%-98.8% in the nucleotide sequence. The nsp2 genes of the seventeen isolates had 74.9%-100% nucleotide sequence identities with each other. This study was undertaken to assess the regional variation of prevalent PRRSV and to establish a sequence database for PRRSV molecular epidemiological studies.

E2 is an envelope glycoprotein of Classical swine fever virus (CSFV) and contains sequential neutralizing epitopes to induce virus-neutralizing antibodies and mount protective immunity in the natural host. In this study, four antigen domains (ABCD) of the E2 gene was cloned from CSFV Shimen strain into the retroviral vector pBABE puro and expressed in eukaryotic cell (PK15) by an retroviral gene expression system, and the activity of recombinant E2 protein to induce immune responses was evaluated in rabbits. The results indicated that recombinant E2 protein can be recognized by fluorescence antibodies of CSFV and CSFV positive serum (Lanzhou Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Lanzhou, China) using Western blot, indirect immunofluorescence antibody test (IFAT) and ELISA, Furthermore, anti-CSFV specific antibodies and lymphocyte proliferation were elicited and increased by recombinant protein after vaccination. In the challenge test, all of rabbits vaccinated with recombinant protein and Chinese vaccine strain (C-strain) were fully protected from a rabbit spleen virus challenge. These results indicated that a retroviral-based epitope-vaccine carrying the major antigen domains of E2 is able to induce high level of epitope-specific antibodies and exhibits similar protective capability with that induced by the C-strain, and encourages further work towards the development of a vaccine against CSFV infection.

Objective To investigate the effect of sulforaphane on 1-methyl-4-phenylpyridinium (MPP +)-induced cell viability loss in cultured PC12 cells and to explore the possible mechanism.Methods MPP + induced damage in PC12 cells was prepared as oxidative damage model.Sulforaphane (0.5,1.O,2.5,5.0 and 10.0 μmol/L) was added in each group cell growth medium.Subsequent experiments were divided into 4 groups:(A) normal control group,(B) sulforaphane group,(C) MPP+ injury group,(D)sulforaphane pretreatment + MPP+ injury group.Cell viability was detected by MTT assay,and the sulforaphane pretreatment PC12 cell viability was observed in different concentrations.Flow cytometry was used to detect changes in the rate of apoptosis in different packet PC12 cells,and protein expression levels of nuclear factor erythroid2-related factor 2 (Nrf2),heme oxygenase (HO-1) and human NAD (P) H dehydrogenase,quinone 1 (NQO1) were detected by Western blot when the PC12 cells were incubated with sulforaphane (2.5 μmol/L) and (or) MPP+ (500 μmol/L) for 24 h in vitro.Results Compared to control group (cell survival rate was 98.70％),the survival percents of PC12 cells were significantly decreased in MPP+-treated group (58.16％).A significant difference was showed between group A and C (F =21.83,P ＜ 0.05),and the cell survival rate in group D was significantly improved.Compared to control group,the rate of apoptosis in MPP+ injury group was increased,and the rate of apoptosis after pretreatment of the sulforaphane was significantly reduced.Compared to MPP+ injury group,the levels of Nrf2,HO-1 and NQO1 protein expression were significantly increased in sulforaphane pretreatment group.Conclusion Sulforaphane have a protective effect against MPP+-induced PC12 cell model damage,and the protective effect may be achieved by activating the Nrf2-antioxidant response element pathway.
