Objective To explore the effect of the recombinant plasmid pcDNA3.1/C-sis on fulminant hepatic failure (FHF) in rats.Methods 48 h after recombinant plasmid pcDNA3.1/C-sis being imported into rat liver by using the method of fluid mechanics,FHF in rats was induced by endotoxin (LPS)+D-galactosamine (D-GaIN).With fluorescence quantitative PCR and Western blotting,C-sis expression was tested.The apoptosis of rat liver was detected by using HE staining and measuring Caspase-3 activity.The expression changes of Bcl-2 and Bax were examined through using Western blotting.The mortality rate of rats was calculated during 24 h observation period.Resnlts Compared with the normal control group and FHF+ empty plasmid group,C-sis mRNA and protein expression levels were increased significantly in the FHF+C-sis plasmid group,there were statistically significant differences (P＜0.01).Compared with the normal control group,the apoptotic hepatocytes were increased in the FHF + Ringer's solution injection group and FHF+ empty plasmid group;compared with FHF+ empty plasmid group,the apoptotic hepatocytes in the FHF+C-sis plasmid group were decreased.Compared with the normal control group,Caspase-3 expression level was increased in the FHF+ Ringer's solution injection group (P＜0.01);compared with the FHF+ empty plasmid group,Caspase-3 expression level in the FHF+C-sis plasmid group was decreased (P＜0.05).Compared with the normal control group,Bcl-2 expression level was decreased significantly (P＜0.01),and Bax expression level was increased significantly (P＜0.01) in the FHF+Ringer's solution injection group;compared with the FHF+ empty plasmid group,the Bcl-2 expression level was increased (P＜0.05),and Bax expression was decreased (P＜0.05)in the FHF+C-sis plasmid group.During the 24 h observation period,all rats in the normal control group were alive;the mortality rates of the FHF+ Ringer's solution injection group and FHF+ empty plasmid group were 70.0％ and 80.0％ respectively,while that of the FHF+C-sis plasmid group was only 20.0％.Conclusion C-sis gene could inhibit FHF in rats induced by LPS+D-GalN.

In order to explore the value of combined detection of atypical lymphocytes (ATL) and transaminase (alanine aminotransferase, ALT; asparate aminotransferase, AST) in the diagnosis of infectious mononucleosis (IM), The data of blood routine and liver function were collected from 54 IM patients, 34 acute hepatitis (AH) patients, 44 upper respiratory infection (URI) patients in Union Hospital during March 2002 to March 2005. Same data were also collected from 40 healthy children as normal control. These data were analyzed retrospectively. Both proportion of atypical lymphocytes and enzyme activity of transaminase were elevated simultaneously (ALT > 40 IU/L, AST > 45 IU/L) in 57.4% (31/54) IM patients. There was significant difference (P < 0.01) between IM group and the other groups. Combined detection of atypical lymphocytes and transaminase can be regarded as a diagnostic marker of infectious mononucleosis.

Objective To detect the levels of the mRNA expression of TIM-3,TIM-1,T-bet,GATA-3,IFN-γ,IL-4 and Galectin-9 in the peripheral blood monocytes (PBMCs) of the patients with Graves disease(GD),and to explore their potential role in the pathogenesis of GD.Methods We used fluorescence quantitative real-time reverse transcription-polymerase chain reaction to measure the mRNA expression of TIM-3,TIM-1 and other associated genes in PBMCs of 70 patients with GD and 22 healthy controls.In addition,we analyzed the relationship of TIM-3,TIM-1 and other associated genes.Results The expression of TIM-3 and TIM-1 mRNA in the PBMCs from GD patients were abnormally higher,the GD patients with Graves' ophthalmopathy group had significantly higher level of TIM-3 mRNA expression than that of GD patients without Graves' ophthalmopathy group,but no statistically significant difference was found in the expression of TIM-1 mRNA.Untreated GD patients had significantly higher level of TIM-3 mRNA expression than that of GD patients in recurrence group,however the expression of TIM-1 mRAN was opposite.But no statistically significant difference was found in TIM-3 mRNA expression of recovery GD patient and healthy control group.Though the expression of TIM-1 mRNA was significantly decreased,it was still higher than that of the normal control group.Conclusion TIM-3 and TIM-1 may participate in the occurrence,development and turnover of GD.TIM-3 or TIM-1 may prove to be an important target for developing new drugs and treatments to GD.

Objective: To investigate the association between three single nucleotide polymorphisms-2562G＞A,-416C＞G and-232G＞A in Tim-3(T cell immunoglobulin domain and mucin domain protein 3)gene promoter region and child allergic asthma in Chinese Han population by using family-based association study.Methods: Genotypes of 3 SNPs(-2562G＞A,-416C＞G and-232G＞A)in 118 allergic asthma nuclear pedigrees were analyzed by restriction fragment length polymorphism.The genotype data were analyzed by using the family-based transmission disequilibrium test(TDT).Haplotypes and their frequencies were established and analyzed by TRANSMIT software.Results: ①No transmission disequilibrium was found at the-2562G＞A and-232G＞A sites from heterozygous parents onto patients in 118 trios analyzed by TDT(P＞0.05);However,at the-416 C＞G locus,the observed values of G allele from heterozygous parents to offspring were significantly higher than the expected values(P＜0.05)②The haplotype TDT analysis by TRANSMIT showed the observed and the expected value in GCA and GGA haplotype from parents to the affected offsprings had significant difference respectively(P＜0.05).The Global X~2 test results also showed that Tim-1 haplotype were associated with child allergic asthma(X~2 = 17.26, P＜0.01).Conclusion: Tim-1 gene promoter-416C＞G locus are associated with allergic asthma susceptibility in Hubei Chinese Han population and the haplotypes constructed by-416C＞G are also associated with asthma.Tim-1 genetic polymorphism may play an important role in the pathogenesis of asthma.

To investigate the distribution characteristics and linkage disequilibrium of T cell immunoglobulin domain and mucin domain protein 4 (TIM4) promoter polymorphisms in asthma patients of Chinese Han population, the promoter region of TIM4 was re-sequenced by PCR-sequencing, and linkage disequilibrium was analyzed by SHEsis software. Four single nucleotide polymorphisms (SNPs) in the promoter region of TIM4 were detected, including two new SNPs (at positions-1609,-153) and two reported SNPs (rs6874202, rs6882076). The frequency distribution of rs6882076 was different among different races (P<0.05). In addition, linkage disequilibrium among the SNPs of the promoter region of TIM4 was found and GGTG was the predominant haplotype. There were four SNPs in the promoter region of TIM4 in asthma patients of Chinese Han population, which were in linkage disequilibrium.
