Antiviral therapy can reduce the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. As for the first-line antiviral drugs, more studies have shown that tenofovir disoproxil fumarate may be better than entecavir in reducing the risk of HCC, especially among Asian patients; a limited number of studies have shown that tenofovir alafenamide fumarate may be better than tenofovir disoproxil fumarate in reducing the risk of HCC; interferon has a better effect than nucleos(t)ide analogues alone in reducing the risk of HCC. Among the currently available drugs, interferon combined with nucleos(t)ide analogues may be the best choice to reduce the risk of HCC in patients at a high risk of HCC. The level of evidence-based medicine is weak for comparing the effect of different drugs in reducing the risk of HCC, and randomized controlled trials are needed for further clarification. In practice, it is necessary to weigh the risk of HCC, drug tolerance and economic affordability based on the patient's basic conditions and actual situations, so as to develop individualized anti-viral strategies.

Objective To study of primary colorectal adenocarcinoma histone H2B single prime generalization (uH2B) and its relationship with clinicopathological parameters.Methods Colonic canceRtissue samples and para-carcinoma tissue of gastrointestinal surgery resection of 83 cases were selected from January 2013 to January 2016 in ouRhospital,and normal colon tissue of 20 cases was collected,and uH2B protein expression level in tissue samples was observed using immunohistochemical staining,and its relationship with clinical pathological parameters of patients with primary colonic carcinoma was analyzed.Results The positive expression rate of uH2B protein in colon canceRtissues was 46.99%,which was loweRthan 83.13% of adjacent tissues and 90.00% in normal colon mucosa,the differences were statistically significant (P<0.05);But there was no significant difference in the positive expression of uH2B protein in adjacent tissues and normal colonic mucosa (P>0.05);The positive expression rate of tumoRuH2B protein in colon canceRtissues in the TNM stage was correlation with degree of differentiation and lymph node metastasis (P<0.05),and it had no significant relationship with the patient′s age,gender,tumoRinvasion depth,tumoRsize (P>0.05).Conclusion The decreased expression rate of uH2B protein in colon carcinoma tissue is correlated with the TNM stage,differentiation degree and lymph node metastasis of the patients.

OBJECTIVE: To investigate the genetic causes of nonsyndromic deaf patients in special educational school of Chifeng city. Inner Mongolia by genetic screening testing method. This study focused on analyzing mutations of coding sequence of GJB2, GJB3 and GJB6 gene. METHOD: DNA were extracted out from peripheral blood of 134 nonsyndromic deaf probands of Chifeng special educational school and 100 normal hearing controls in northern China. First, GJB2 gene mutation was analyzed by direct sequencing for its only exon in the open reading frame. Individuals found with heterozygous GJB2 mutation were given further testing for GJB6 del(GJB6-D13S1830) and direct sequencing for its exon. In 91 probands with unknown genetic cause (excluding probands who carried mtDNA A1555G mutation and GJB2 gene bi allele mutation and probands who were diagnosed as enlarged vestibular aqueduct by temporal CT), GJB3 gene mutation was analyzed by direct sequencing for its exon. RESULT: The sequencing results revealed that forty-one cases carried GJB2 mutation. of which twenty-two were homozygous or compound heterozygous and nineteen were heterozygous. Further testing for GJB6 del(GJB6-D13S1830) and analysis of its coding sequence in GJB2 heterozygous cases showed no positive result. Four subjects in control group carried pathogenetic mutation of GJB2 gene. Six types of novel variants of GJB2 gene were detected. Of the 91 deaf probands with unknown etiology. two probands were found carrying heterozygous pathogenetic mutation of GJB3 gene. one of whom also carried GJB2 235delC heterozygous mutation. One subjects in the control group carried pathogenetic mutation of GJB3 gene. Three types of novel variants of GJB3 gene were found. CONCLUSION By screening GJB2.GJB3 and GJB6 gene, we found 32.1% probands carrying GJB2, GJB3, and GJB6 mutations and we are able to determine genetic cause related to these three genes from one family for 16.42 percent of nonsyndromic deaf probands in special educational school of Chifeng city. The discovery of novel variants of GJB2 and GJB3 gene makes the mutational and polymorphic spectrum more plentiful in Chinese population.
