[Construction and expression of fusion gene encoding Hyper-IL-6 in mammalian cells].

AIM: To construct and express fusion gene encoding Hyper-IL-6 in mammalian cells. METHODS: Using geneSOEing method, human sIL-6R cDNA was fused with IL-6 cDNA by a linker rich in glycine through PCR technique and cloned into pIRES(2)-EGFP. The constructed plasmid was transfected into mammalian cells. The expression of fusion gene encoding Hyper-IL-6 was detected by GFP and RT-PCR and immunocytochemistry. RESULTS: The recombinant plasmid pIRES-HIL-6 was successfully constructed and expressed in mammalian cells. CONCLUSION: The success in construction and expression of human Hyper-IL-6 makes it possible to further study its biological functions.

[The effect of artificial support system on serum cytokine in chronic severe hepatitis].

OBJECTIVE: To explore the changes of cytokines including TNFalpha, TGFbeta1 and nitrogen monoxide, and endotoxin in the serum of chronic severe hepatitis after the treatment of ALSS, and to evaluate further the value of ALSS in the treatment of chronic severe hepatitis. METHODS: Forty two patients were screened. The changes of TNFalpha, TGFbeta1, nitrogen monoxide and endotoxin were detected respectively. The relationship between the cytokines and the severity and prognosis were further analyzed. RESULTS: ALSS was effective to decrease the serum concentration of cytokines. TNFalpha dropped from (481.57+/-229.33) pg/ml to (156.46+/-78.12) pg/ml (P < 0.05). TGFbeta1 from (44.09+/-31.73) ng/ml to (27.77+/-23.28) ng/ml (P < 0.01), endotoxin from (1.05+/-0.37) Eu/ml to (0.28+/-0.22) Eu/ml (P < 0.001). NO from (71.15+/-33.09) micromol/L to (58.11+/-29.30) micromol/L (P < 0.001). Before the therapy endotoxin was related with TNFalpha and total bilirubin, while after the therapy, NO was related with protime and aminonemia. CONCLUSION: High level of endotoxin and nitrogen monoxide in serum plays an important role in hepatocyte damage of chronic severe hepatitis. The changes of serum endotoxin TNFalpha, TGFbeta1 and nitrogen monoxide level in patients with chronic severe hepatitis can be used to judge the severity and prognosis of severe hepatitis. ALSS is a reliable hepatic support device for chronic severe hepatitis
