Objective To explore the application of interferon(IFN)response-related genes in predicting the outcome of antiviral treatment in chronic hepatitis C. Methods SuperArray microarray was used to detect the expression of IFN response-related genes in peripheral blood monocytes(PBMC)from chronic hepatitis C patients before treatment. SPSS 12.0 was used for statistical analysis. Results Ten patients were classified as rapid responders(RVR)and seven patients as non-RVRs according to the serum HCV RNA level after 4 weeks of treatment in 17 patients. Compared with healthy controls, nine differentially expressed genes were found in RVR patients, one up-regulated and eight down-regulated; eighteen differentially expressed genes were found in N-RVR patients, all down-regulated. Five differentially expressed genes were found between the patients with RVR and N-RVR: four up-regulated genes were PRKCZ, PRKRA, IRF5 and TNFSF10(t =5.44, 3.13, 5.24 and 2.30, P=0. 000, 0.010, 0.005 and 0. 044); one up-regulated gene was IFIT5(t = 2.43, P = 0. 035). Of seventeen patients, 12 were HCV genotype 1b, 5 were HCV genotype 2a. Compared with HCV2a, IFI6 and IFI44 gene in HCV1b were downregulated(t = 2.42 and 2.45, P = 0. 038 and 0. 033). Conclusions The expression of IFN responserelated genes is associated with response to IFN treatment. HCV genotype 1 b is more successful in inducing the down-regulation of IFN response-related genes than that of HCV genotype 2a, thus leading to the resistance to IFN.

In order to investigate the effects of pyrolysis conditions on bio-oil production from biomass in molten salt, experiments of biomass pyrolysis were carried out in a self-designed reactor in which the molten salt ZnCl2-KCl (with mole ratio 7/6) was selected as heat carrier, catalyst and dispersion agent. The effects of metal salt added into ZnCl2-KCl and biomass material on biomass pyrolysis were discussed, and the main compositions of bio-oil were determined by GC-MS. Metal salt added into molten salt could affect pyrolysis production yields remarkably. Lanthanon salt could enhance bio-oil yield and decrease water content in bio-oil, when mole fraction of 5.0% LaCl3 was added, bio-oil yield could reach up to 32.0%, and water content of bio-oil could reduce to 61.5%. The bio-oil and char yields were higher when rice straw was pyrolysed, while gas yield was higher when rice husk was used. Metal salts showed great selectivity on compositions of bio-oil. LiCl and FeCl2 promoted biomass to pyrolyse into smaller molecular weight compounds. CrCl3, CaCl2 and LaCl3 could restrain second pyrolysis of bio-oil. The research provided a scientific reference for production of bio-oil from biomass pyrolysis in molten salt.

OBJECTIVE: To investigate the relationship between ATP-binding cassette subfamily B member 1 (ABCB1) polymorphism and tacrolimus-related adverse drug reactions in renal transplant patients during perioperative period. METHODS: Totally 170 patients who underwent renal transplantation from Nov. 2014 to Mar. 2018 in our hospital as well as were tested for their ABCB1 C1236T (rs1128503), ABCB1 G2677T/A (rs2032582) and ABCB1 C3435T (rs1045642) genotype were selected in this study. χ2 test was used to compare the incidence of tacrolimus-related ADR among patients with different genotypes. The related adverse reactions included digestive tract reaction, pulmonary infection, renal dysfunction, abnormal liver function, elevated blood sugar, elevated blood lipid and decreased white blood cells. Logistic regression model was used to analyze the unit point risk. The main haplotypes of the above genes were analyzed by PHASE software, and their correlation with tacrolimus-induced ADR was analyzed. RESULTS: Among 170 patients, 21 cases (12.3%) of CC type, 78 cases (45.9%) of CT type and 71 cases (41.8%) of TT type were detected by ABCB1 C1236T (rs1128503). ABCB1 G2677T/A (rs2032582) test showed that 25 cases (14.7%) were GG type, 95 cases (55.9%) were GA+GT type and 50 cases (29.4%) were AA+AT+TT type. ABCB1 C3435T (rs1045642) test showed that 57 cases (33.5%) were CC type, 82 cases (48.2%) were CT type and 31 cases (18.3%) were TT type. There was no significant difference in the incidence of digestive tract reaction, pulmonary infection, renal dysfunction, elevated blood sugar, elevated blood lipid and decreased white blood cells among patients with different ABCB1 genotypes (P>0.05). However, there was significant difference in the incidence of abnormal liver function between ABCB1 C1236T (rs1128503) and ABCB1 C3435T (rs1045642) genotypes (P<0.05). There was no significant difference in the incidence of abnormal liver function among ABCB1 G2677T/A (rs2032582) genotypes (P=0.069), but P was lower than 0.1. Logistic regression analysis showed that ABCB1 C1236T (rs1128503) CC genotype [OR=4.959, 95%CI (1.700, 14.468), P=0.003], ABCB1 G2677T/A (rs2032582) GG genotype [OR=3.500, 95%CI (1.164, 10.524), P=0.026] and ABCB1 C3435T (rs1045642) CC genotype [OR=3.033, 95%CI (1.012, 9.095), P=0.048] were risk factors for tacrolimus-related abnormal liver function. ABCB1 CGC haplotype was the main haplotype. There was significant difference in the incidence of abnormal liver function caused by tacrolimus between ABCB1 CGC haplotype and non-ABCB1 CGC haplotype (P=0.002), and it was also a risk factor for tacrolimus-related liver dysfunction [OR=3.173, 95%CI(1.512, 6.656), P=0.002]. CONCLUSIONS: The abnormal liver function of ABCB1 CGC haplotype kidney transplantation patients is more likely to occur when tacrolimus is administered during the perioperative period.
