Objective To establish a continuous monitoring assay of serum argininosuccinate lyase (ASL) activity with automatic biochemistry analyzer, and perform methodology validation and preliminary clinical application.Methods According to the chemical reaction catalyzed by ASL and the working characteristics of automatic biochemistry analyzer, an enzyme coupled reaction system with high specificity was set up, and the methodology validation was performed.Three hundred and nine patients with various liver diseases, 269 non-liver disease patients and 40 healthy controls were enrolled in this study.Serum ASL, ALT, and AST level were determined in all subjects.Results A new kinetics assay of ASL activity was set up with automatic biochemistry analyzer.The methodological validation demonstratod that inter-assay and intra-assay coefficient of variation were 4.0% and 5.9% respectively and the mean recovery was 100.5%.The linear range was 0-167.7 U/L.The lowest detection limit was approximately 0 U/L.The interference test showed that there is no significant interferences while the concentration of bilirubin is less than 342 μmoL/L or commonly used anticoagulants is employed at their routine concentrations.However,interference was significant when Hb level is more than 0.06 g/L.Preliminary study of clinical application showed that there was no significant difference of serum ASL level between non-liver disease group and healthy group ( q = 0.027, P = 0.979 ), but there was significant differences for both serum ALT and AST levels (ALT:q =6.461,P =0.000;AST:q =6.481,P =0.000).Conclusions A continuous monitoring assay for the determination of serum ASL activity is successfully established. Serum ASL may be a good biomarker for liver injury.

Type 1 diabetes is a autoimmune disease that occurs under the influence of both genetic predisposition and environmental factors,mediated mainly by T lymphocytes with various kinds of other involved immune cells.The autoimmune attacks eventually lead to the islet beta cell destruction and insulin insufficiency.Multiple fundamental studies and clinical trials have revealed that umbilical cord blood pluripotent stem cells have the potential to help restore immune balance,induce immune tolerance,stop the autoimmune attacks against beta cells,and promote beta cell regeneration in type 1 diabetes mellitus (T1DM),by means of cell to cell contact and soluble cytokine secretion.For the past few years,the National Clinical Research Center for Metabolic Diseases of Second Xiangya Hospital has been leading the research on stem cell education therapy and has performed the therapy for 35 juvenile type 1 diabetes patients from China and foreign countries,introducing a novel treatment for T1DM.

Objective To clone shRNA (short hairpin RNA) recombinant plasmid targeting on COX-2 gene and analyze the nucleic acid sequence of the recombinant plasmid. Methods One pair of 21 bp reverse repeated sequence targeting on COX-2 mRNA spaced by 9 bp nucleotides were synthesized. The complement double strands was formed by annealing and inserted into plasmid pGenesil-1 to generate eukaryotic expression plasmid.

According to slope of standard curve (-3.513)and correlation cofficient(0.999),amplification efficiency of the system was 92.6%.Coefficient variation of intra-assay,intra-day and inter-day-assay were 2.1%,4.0% and 6.8%,respectively.Sensitivity of FQ-PCR Was 2 eopies/μl.Expressions of HGF mRNA in lymphoma group Was higher than that in control group(6.425±2.172 and 0.317±0.192,respectively,t=15.883,P<0.001),and its expressions in remission group was lower than no remission group(6.157±1.712 and 7.59l ±1.184,respectively,t=2.768,P<0.05).However,there Was not difference of HGF mRNA level between group HD and group NHL(P>0.05).According to ROC analysis,its sensitivity and specificity were 93.6% and 100% when cutoff value for lymphoma clinical diagnosis Was 3.136.Conclusion HGF mRNA'8 quantitative standard and its real time F9-PCR analysis system have been successfully constructed,and it can be used for quantitative detection of its mRNA expression in lymphoma.

Objective To detect quantitatively hepatocyte growth factor(HGF)mRNA expressions of bone marrow mononuclear cells(MNCs)in acute leukemia(AL)and investigate its clinical significance.Methods Total mRNA of quantitated bone marrow MNCs isolated from 67 de novo AL cases was extrated and then cDNA was synthesized.Expression of HGF mRNA was quantified absolutely using real-time fluorescence quantification PCR(FQ-PCR).Results Expressions of HGF mRNA in a group of AL were higher significantiv than these in a control group(6.936 ±1.613,0.407 ±0.170,P<0.001),but there was similafitv between a group of acute myeloid leukemia(AMI,)and group of acute lymphoblastic leukemia (ALL)(7.127±1.911,6.635±0.934,P>0.05).In AL subtypes,the expression of M5(9.998 4±1.454)was higher than that of M2,M3,M4,L1,L2 and L3(P<0.001),but there ware no differences among the latters(P>0.05). Meanwhile,there was no statistical significance on the expressions of HGF mRNA between different age and sex(P>0.05).In addition,expressions of HGF mRNA in the remission group were lower than these in the non.remission group(6.393±1.165,8.041±1.848,P<0.005).Conclusions There are statistical significances of the expressions of bone marrow MNCs HGF mRNA among the AL group and control group.As to AL subtypes,there are no statistically significant differences between AML and ALL as well as between different age and sex.Besides,lower HGF mRNA level is correlated with better curative effect.It is suggested that HGF mRNA is a suitable index for AL diagnosis and treatment.
