Objective To study the protective effect of interleukin-33 (IL-33) on mouse warm hepatic ischemia-reperfusion (I/R) injury.Methods On a mouse warm hepatic I/R injury model IL-33 mRNA and protein levels during hepatic ischemia and reperfusion period were determined,and then mice were divided into control group,model group,recombinant IL-33 intervention group and anti ST2L antibody intervention group,and mice were sacrificed after 6 hours of reperfusion.Serum aspartate aminotransferase (AST),alanine aminotransferase (ALT) protein levels were determined.Liver pathology was observed by transmission electron microscopy and serum cytokine level (tumor necrosis factor-α,interferon-γ,IL-4,IL-5,IL-13) were measured by flow cytometry CBA method.Results The level of IL-33 mRNA and protein were significantly higher in the reperfusion stage (t2 h =-3.574,t6 h =-4.147 ; P ＜ 0.05).After intervention by recombinant IL-33,the level of serum ALT and AST decreased significantly (tALT =4.592,tAST =3.471 ; P ＜ 0.05),the severity of pathological damage was reduced,the levels of IL-4,IL-5,IL-13 increased and that of IFN-γ decreased,with statistically significant difference in comparison with the control groups (tIL-4 =-4.995,tIL-5 =-4.584,tIL-13 =-4.431 ; P ＜ 0.05).Anti-ST2L antibody intervention effected the opposite.Serum TNF-α level did not change in intervention groups compared with that in model group (tTNF-α =0.261,P ＞ 0.05).Conclusions IL-33 mRNA and protein level increased in mice with hepatic I/P injury.IL-33 exerts a protective effect on the I/R injured liver after binding to its receptor ST2L.

Aim To study the effect of simvastatin(Sim) on left ventricular remodeling and heart function in rats with myocardial infarction(MI).Methods Myocardial infarction models were successfully induced by ligation of anterior descending coronary artery.24 h later the survivals were randomly divided into 3 groups.① MI group;② 20 mg Sim group(20 mg?kg~(-1)?d~(-1));③ 40 mg Sim group(40 mg?kg~(-1)?d~(-1)).The rats with sham ligation formed sham group.After 8 weeks,hemodynamic parameters,blood serum lipids,the ratio of RV and LV weight to body weight(RVWI,LVWI) were examined.The pathomorphological change and the collagen volume fraction(CVF) were analyzed by PSR dyeing.Results There were no significant differences in values of serum lipids among 4 groups.Compared with sham group,the left ventricular end-diastolic pressure(LVEDP) was increased and left ventricular systolic pressure(LVSP) was depressed significantly in MI group; the RVWI and LVWI and the CVF in border infarcted zone and Ⅰ/Ⅲ ratio were increased in MI group too.Compared with MI group,Sim partially normalized LVSP and LVEDP;abated ventricular weight index;reduced CVF in non-infarction zone in both Sim groups.Conculusion Simvastatin improves LV remodeling and heart function in rats with MI,which is associated with the effect of limiting myocardial hypertrophy and interstitial fibrosis.

Aim To assess the effect of HMG-CoA inhibitors simvastatin on collagen remodeling in rats after myocardial infarction. Methods Myocardial infarction models were induced by ligation of anterior descending coronary artery. 24 hours later the survivals were randomly divided into 3 groups: (1) MI group; (2) 20 mg Sim group(20 mg? kg-1? d-1); (3) 40 mg Sim group(40 mg? kg-1? d-1). Rats with sham ligation formed into Sham group. After 8 weeks, the ratios of LV and RV weight to body weight (RVWI, LVWI) were examined and the collagen content was detected. The type Ⅰ and type Ⅲ collagen volume fraction (CVF) and Ⅰ/Ⅲ ratio in infarcted and non-infarcted zones were examined with PSR dyeing; also the mRNA expressions of type Ⅰ and type Ⅲ collagen in non-infarcted zone (NIZ) were detected with RT-PCR.Results Comparing with Sham group,the RVWI and LVWI in MI group increased significantly. The type Ⅰ CVF and type Ⅲ CVF in NIZ and the Ⅰ/Ⅲ ratio were increased in MI group. The mRNA expressions of type Ⅰ and type Ⅲ collagen in NIZ in MI group were higher than those in Sham group. Comparing with MI group, the RVWI and LVWI in both Sim groups were decreased significantly. The type Ⅰ CVF and type Ⅲ CVF in NIZ and the Ⅰ/Ⅲ ratio were depressed in both Sim groups, and the mRNA expressions of collagens were also lower than those in MI group, but higher than those in Sham group. Conculusion Simvastatin could attenuate the development of myocardial interstitial fibrosis in non-infarction zone to improve myocardial interstitial remodeling in rats after MI.

To establish induction and liquid culture system for hairy roots of Danshen (Salvia miltiorrhiza), Agrobacterium rhizogenes A4, LBA9402, 15834 as test bacterium were used to infect aseptic leaves of Danshen. The hairy roots were induced and positive transgenic hairy roots were selected with PCR using rolB and rolC as the target gene. Then hairy roots of S. miltiorrhiza were harvested and salvianolic acids were extracted with 70% methanol containing 1% formic acid. The content of salvianolic acid B (SalB) and rosmarinic acid (RA) were determined by HPLC. According to the above research results, the Danshen hairy roots induced by A. rhizogenes LBA9402 were inoculated into the following group of culture media: MSOH, MS, B5, and 6,7-V liquid media. Then the same methods of extraction and determination for the content of Danshen hairy roots were adopted. Last, the hairy roots of S. miltiorrhiza induced by A. rhizogenes LBA9402 were inoculated into the MSOH liquid media with different pH values. The content of salvianolic acid were extracted with 70% methanol containing 1% formic acid and determined by HPLC. As a result, three kinds of A. rhizogenes A4, LBA9402, 15834 could induce hairy roots and Ri plasmids were integrated into the genome of S. miltiorrhiza by PCR. Danshen hairy roots induced by A. rhizogenes LBA9402 and A4 produced much more salvianolic acid, which were (3.27 ± 0.37)% [including (1.04 ±0.36)% of RA and (2.22 ± 0.29)% of SalB] and (3.17 ± 0.20)% [including (0.92 ± 0.31)% of RA and (2.25 ± 0.26)% of SalB], respectively. Hairy roots induced by A. rhizogenes LBA9402 when they were cultured in MSOH liquid media produced much more salvianolic acid, which was (4.56 ± 0.36)%, including (1.12 ± 0.26)% of RA and (3.44 ± 0.23)% of SalB. Hairy roots induced by A. rhizogenes LBA9402 produced the most salvianolic acid when they were cultured in MSOH liquid media with the pH value 4.81, which was 4.85%, including 1.16% of RA and 3.69% of SalB. So Danshen hairy roots induced by A. rhizogenes LBA9402 and A4 produced much more salvianolic acid when they were cultured in MSOH liquid media with the pH value 4.81. The research had established the foundation on genetic engineering to improve the quality of S. miltiorrhiza.

The evolution of hepatocellular carcinoma (HCC) is a compound process which involves many kinds of genes and transductional pathways. The expression of the peptidyl-proplyl-isomerase PIN1 gene, the mutation in exon 3 of beta-catenin and its correspondent abnormal expression and their roles in the hepatocellular carcinogeneisis were investigated. Among 29 pair cases of HCC and non-carcinoma tissues, the expression of PIN1 gene was detected by immunochemical staining. Mutations in exon 3 of beta-catenin gene and differential expression of beta-catenin gene were investigated by the methods of PCR-SSCP, direct sequencing and immunohistochemical technique as well. The results indicated: (1) 44.8% (13/29) cases of HCC presented higher level of PIN1 gene expression than non-cancerous tissues (chi2=32.63, P<0.05), especially in cytoplasm and nucleus, while there was lower level of PIN1 expression in non-cancerous tissues; (2) 58.6% (17/29) HCC tissues showed beta-catenin protein accumulation in cytoplasm and nucleus. 46.2% (6/13) HCC tissues indicated beta-catenin protein accumulation with higher level of PIN1 expression, while 53.8% (7/13) HCC tissues indicated beta-catenin protein accumulation with lower level or trace of PIN1 expression (chi2=0.00, P>0.05); (3) 24.1% (7/29) of primary tumor lesions carried gene mutations in exon 3 of beta-catenin, and accompanied by beta-catenin protein accumulation. There was no mutation in non-cancerous tissues. All the mutation presented in tissues with low level of PIN1 expression. There was no mutation of beta-catenin gene in tissues with high PIN1 expression level (chi2=58.12, P<0.05). So it was postulated that the increase of PIN1 gene expression could promote hepatocellular carcinogenesis via a way different from beta-catenin gene mutation.

To optimize the immunization strategy against HIV-1, a DNA vaccine was combined with a recombinant vaccinia virus (rTV) vaccine and a protein vaccine. Immune responses against HIV-1 were detected in 30 female guinea pigs divided into six groups. Three groups of guinea pigs were primed with HIV-1 DNA vaccine three times, boosted with rTV at week 14, and then boosted with gp140 protein at intervals of 4, 8 or 12 weeks. Simultaneously, the other three groups of animals were primed with rTV vaccine once, and then boosted with gp140 after 4, 8 or 12 weeks. The HIV-1 specific binding antibody and neutralizing antibody, in addition to the relative affinity of these antibodies, were detected at different time points after the final administration of vaccine in each group. The DNA-rTV-gp140 immune regimen induced higher titers and affinity levels of HIV-1 gp120/gp140 antibodies and stronger V1V2-gp70 antibodies than the rTV-gp140 regimen. In the guinea pigs that underwent the DNA-rTV-gp140 regimen, the highest V1V2-gp70 antibody was induced in the 12-week-interval group. However, the avidity of antibodies was improved in the 4-week-interval group. Using the rTV-gp140 immunization strategy, guinea pigs boosted at 8 or 12 weeks after rTV priming elicited stronger humoral responses than those boosted at 4 weeks after priming. In conclusion, this study shows that the immunization strategy of HIV-1 DNA vaccine priming, followed by rTV and protein vaccine boosting, could strengthen the humoral response against HIV-1. Longer intervals were better to induce V1V2-gp70-specific antibodies, while shorter intervals were more beneficial to enhance the avidity of antibodies.
