OBJECTIVETo observe the clinical effect of Guilu Erxian Glue Cataplasm (GEGC) on carcinoma of the large intestine patients with myelosuppression after chemotherapy, and further to confirm its efficiency and safety.

METHODSTotally 60 patients with carcinoma of the large intestine were randomly assigned to two groups. Meanwhile, they all accepted FOLFIRI chemotherapy. Patients in the treatment group were additionally applied at Shenque (RN8), exchanging once per every other day, for 14 successive days. Patients in the control group took placebos with the same dose and dosage as the treatment group. The blood cell counts (WBC, NE, and PLT) were detected before chemotherapy, at day 7, 10, and 14. The TCM symptoms integrals, Karnofsky performance score (KPS), liver and kidney functions were observed before chemotherapy, at day 7 and day 14. Adverse skin reactions were observed each day. And the usage of hematopoietic growth factors was recorded.

RESULTS(1) The KPS score at day 7 was more stable in the treatment group than in the control group; the WBC and NE counts in the peripheral blood at day 14 were higher in the treatment group than in the control group; and TCM symptoms integrals at day 14 was lower in the treatment group than in the control group, all with statistical difference (P < 0.05). (2) Compared with the control group, the PLT count was higher in the treatment group than in the control group, the usage of rhG-CSF and antibiotics was less in the treatment group than in the control group, all with no statistical difference (P > 0.05). (3) No obvious adverse reactions such as liver injury, renal injury, or skin allergy were observed.

CONCLUSIONSAdjuvant treatment of GEGC could improve carcinoma of the large intestine patients with myelosuppression to some extent. No relevant adverse reactions were found.

OBJECTIVETo explore a new strategy for effective and economical anti-virus therapy for HBV infection, we conducted a sequence administration of lamivudine and interferon alpha 1b to evaluate its effects on HBV replication and rebound as well as YMDD mutation induced by lamivudine.

METHODS150 HBV patients having at least 6 months history of infection were assigned randomly into 5 groups. Each group of these patients was either treated with lamivudine, interferon alpha 1b, lamivudine combined with interferon, sequence administration of lamivudine and interferon (sequence group) or no anti-virus therapy (control group) for 12 months. The serum samples were collected at 0, 3, 6, 9, 12 and 18th months and were assayed for ALT, AST, HBeAg, HBV DNA (quantitive PCR) as well as YMDD mutation types by microarray.

RESULTSThe anti-virus replication effects were shown as early as the 3rd month in the sequence group but not in the IFN and control groups. The significant and persistent inhibition effect of it on HBV replication and improvement of liver function was shown. It was more effective than lamivudine or IFN treatments at the end of the drug administration and 6 months later after the drug was withdrawn. We also found that this sequence administration pattern can significantly shorten the period of treatment of lamivudine as well as reduce the rate of YMDD mutation and rebound of HBV replication after lamivudine withdrawal. It is also more economical than a combined therapy of lamivudine with IFN.

CONCLUSIONThis sequence administration of lamivudine and IFN pattern can significantly improve the anti-virus effect on HBV replication, shorten the period of treatment with lamivudine, reduce the mutation rate of YMDD and prevent the rebound of HBV after drug withdrawal.

OBJECTIVETo construct four expression vectors carrying enhanced green fluorescent protein (EGFP) gene under the control of different HBV promoters, and to detect and analyze their expressions in hepatoma cell lines.

METHODSFour HBV promoters were amplified using PCR, and they were inserted into the T-vector and identified using restriction enzymes and sequencing, then cloned into the expression vector pEGFP-1. The four recombinant plasmids were transfected into human hepatoma cell line HepG2 by lipofectamine2000, and the positive cell clones were detected using fluorescence microscopy.

RESULTSAll target fragments were separately obtained and successfully cloned into the expression vector. The expressions of EGFP under the control of the four promoters were detected. The expressions of EGFP controlled by different promoters had some differences.

CONCLUSIONSReporter gene EGFP under the control of four HBV promoters can be specifically expressed in hepatoma cell line HepG2, and different promoters give different results; this may provide another option in gene therapy of liver diseases.

OBJECTIVETo study whether liver cirrhosis and portal hypertension are associated with ET-1 TaqI polymorphism and TNFa promoter-308G to A polymorphism.

METHODSA case control study of 106 patients with liver cirrhosis following HBV C infection was performed in comparison with 108 controls by PCR-RFLP.

RESULTSThe frequency of C allele and CC+TC genotype in TaqI polymorphism of ET-1 gene in the portal hypertension group (LC+) was significantly higher than that in the healthy controls, and the frequency of TNF2/1 genotype in TNFa promoter -308 G to A polymorphism in LC+ group was significantly higher than that in the control group. The results by stratification analysis showed that TCF2 genotype frequency was higher in the LC+ group than in the control group. ET-1 TaqI polymorphism and TNFa polymorphism were risk factors for the occurrence of portal hypertension by Logistic regression analysis.

CONCLUSIONET-1 TaqI polymorphism and TNFa polymorphism are associated with portal hypertension, and are new risk factors for the occurrence of portal hypertension. TCF2 genotype may be a susceptible gene of portal hypertension.
