OBJECTIVETo study the risk factors of hepatitis C Virus Infection among Han population in Henan Province, providing evidence for the development of targeted prevention and control measures.

METHODSIn this 1: 1 matched case-control study, data of 134 cases and 134 controls were collected in seven hospitals from June 2013 to September 2013. Case group with the following conditions: Han nationality, first diagnosed hepatitis C in 2013, Current address and investigation belong to the same district (county), above 18 years old; with the following conditions can't into case group: not to cooperate with the investigation, late-stage Hepatitis C patients. Control group with the following conditions: Han nationality, with the matched case patients the same gender, in the same hospital for treatment , from the same district (county), the age difference ≤ 5 years old and in the same age group. With the following conditions can't into control group:not to cooperate with the investigation, diagnosed with hepatitis B, hepatitis C patients. Collect 3 ml blood samples to test anti-HCV. Single factors were analyzed with χ(2) between case and control, risk factors were analyzed with logistic regression model.

RESULTSThe ratio about blood donation, blood transfusion, operation and acupuncture of cases were 35.1% (47/134), 27.6% (37/134), 42.5% (57/134), 12.7% (17/134), with differences compared to those of controls (2.2% (3/134), 5.2% (7/134), 21.6% (29/134), 5.2% (7/134))(χ(2) values were 47.60, 24.47, 13.42 and 4.58, all P values <0.05). Compared with those never received blood transfusion and those never donated blood, former blood receptors and blood donors had higher risk of hepatitis C infection(OR: 2.01, 95%CI:1.32-3.05; OR:2.68, 95%CI:1.85-3.88).

RESULTSof multiple nonconditional logistic regression analysis showed that Plasma donors and whole blood donors had higher risk of hepatitis C infection than those never donated plasma and blood (OR:76.71, 95%CI: 10.25-574.25; OR:10.23, 95%CI: 2.15-48.70).

CONCLUSIONBlood transfusion and abnormal blood are independent risk factors among Han population in Henan Province of hepatitis C infection. The Plasma donors, blood donors and with the increase in the times of blood transfusion, the risk of hepatitis C infection is increase.

OBJECTIVETo investigate the clinical epidemiological characteristics and the major causes of primary liver cancer (PLC) in Xinjiang region.

METHODSThe clinical epidemiological information on the first page of case history of 3602 PLC patients, which were diagnosed in our hospital from January 2002 to December 2010, were retrospectively reviewed and analyzed.

RESULTSAmong the 3602 cases, the men/women gender ratio was 3.72:1; The proportion of Han, Uighur, Kazakh, and other nationality (Hui, Mongolian, Manchu, Xibo nationality) was 81.95%, 9.30%, 4.14%, 2.89%, and 1.72%, respectively. The comparative difference between Uighur and Han nationalities was significant (P < 0.05). The hepatitis virus detection results showed that HBs-Ag was positive in 1680 cases (59.57%), HCV-Ab was positive in 229 cases (9.41%). Virus detection was negative in 888 patients (24.65%). The hepatitis B virus positive rate in Uygur patients was 36.13% and in Kazakh patients was 40.37%, both significantly lower than that in patients of Han nationality (63.18%, P < 0.05).

CONCLUSIONSIn Xinjiang region, the infection rate of hepatitis B virus in Uygur and Kazak people is significantly lower than that in Han people. The distribution of gender and age does not differ significantly among different nationalities, compared with those in other regions. The prevalence of primary liver cancer in Xinjiang region has certain regional characteristics and features.

Objective: To compare the time and spatial distribution of hepatitis C and HIV/AIDS cases and its correlation, in China from 2012 to 2017. Methods: Data on reported hepatitis C and HIV/AIDS cases was gathered from the Direct Reporting System of Infectious Diseases Information Network in China, 2012 to 2017 while annually collected provincial data was based on the date of review and current address. Correlation of the data was analyzed, using both simple correlation and linear regression methods. Results: The number of reported cases of hepatitis C remained stable in China, in 2012-2017, with the number of annual reported cases as 201 622, 203 155, 202 803, 207 897, 206 832 and 214 023, respectively. The number of reported cases on HIV/AIDS showed a steady growing trend, from 82 434, 90 119, 103 501, 115 465, 124 555 to 134 512. However, the numbers of hepatitis C and HIV/AIDS cases were in the same, top six provinces: Henan, Guangdong, Xinjiang, Guangxi, Hunan and Yunnan. Results from the simple correlation analysis indicated that there was a positive correlation (r>0.5, P<0.01) existed between the above-said two kinds of cases at the provincial level in China, in 2012-2017. Again, results from the linear regression analysis also showed that the correlation coefficient r(s) and year was strongly correlated (r=0.966) while r(s) had been linearly increasing with time. Conclusions: Our data showed that there were temporal and spatial correlations existed between the reported cases of hepatitis C and HIV/AIDS at the provincial level, suggesting that relevant prevention and control programs be carried out in areas with serious epidemics. Combination of the two strategies should be encouraged, especially on prevention and treatment measures related to blood transmission.

BACKGROUND/AIMS: A combination of peginterferon and ribavirin is the standard therapy for chronic hepatitis C (CHC). However, the respective study has not been carried out in a large scale in Korea. The purpose of this study was to collect the studies that have been reported in Korea in order to analyze the therapeutic effect of combination therapy and compare to find racial difference. METHODS: Twenty-eight papers related to the therapeutic effect of combination therapy in CHC patients were analyzed based on pooled analysis. RESULTS: Based on the analysis for genotype 1 in Korea, early virologic response (EVR), end of treatment response (ETR), and sustained virologic response (SVR) were 79.6% (125/157), 80.1% (166/207), and 62.7% (341/543). The EVR, ETR, and SVR for genotype 2 and 3 were 89.4% (119/133), 92.2% (203/220), and 84.1% (434/516). Data from other Asians showed that EVR and SVR for genotype 1 were 88.9% (290/326) and 64.4% (491/762) respectively and 88.8% (135/152), and 79.4% (151/190) for genotype 2 and 3 respectively. In Western, EVR and SVR for genotype 1 were 51.3% (1,981/3,860) and 42.4% (1,798/4,231) respectively, and for genotype 2 and 3 were 87.7% (350/399) and 77.8% (533/685) respectively. Based on the comparative analysis, no statistical difference in SVR between Koreans and other Asians (p=0.955) was observed; However, the SVR of Koreans was higher with significance than that of Westerns (p<0.001) On the other hand, there was no difference what so ever, in SVR for genotype 2 amongst the different races. CONCLUSIONS: The SVR of combination therapy for the Korean chronic hepatitis C patients was similar to other Asians but higher than Westerns.

OBJECTIVEThis study was aimed to understand the clinical characteristics and prognosis in Uighur patients with Non-B Non-C hepatocellular carcinoma (HCC) and virus-related HCC.

METHODSWe retrospectively analyzed the clinical data of 301 Uighur HCC patients, among them, there were 145 NBC-HCC cases and 156 virus-related HCC cases. The overall survival rates of the patients were analyzed by Kaplan-Meier method, and the factors that may influence the prognosis and survival of NBC-HCC patients were analyzed using univariate (Log rank test) and multivariate Cox proportional hazard model.

RESULTSThe differences of the gender, living region, history of diabetes, body mass index (BMI), history of cirrhosis, TNM stage, Child-Pugh scores, total bilirubin, and AFP level between the NBC-HCC group and viral-HCC group were statistically significant (P < 0.05 for all). The 1-, 2-, 3- and 5-year survival rates were 35.6%, 20.3%, 12.6%, and 4.5%, respectively, for all the 301 patients, and no significant difference between these two groups in terms of OS (P > 0.05). Multivariate analysis by Cox model showed that age, TNM staging, PVTT, Child-Pugh scores, TACE combined with radiotherapy or RFA were significant independent prognostic factors (all P < 0.05).

CONCLUSIONSThe clinical characteristics in Uighur patients with non-B non-C HCC and hepatitis virus-related HCC are not all the same and HCC in Xinjiang region has certain regional characteristics and features. Age, TNM stages, portal vein tumor thrombus, Child-Pugh scores, and TACE combined with radiotherapy or RFA are significant independent prognostic factors.

OBJECTIVETo study into the genetic polymorphism of DC-SIGN and DC-SIGNR's exon 4 in Chinese hepatitis C patients and its relationship with HCV infection susceptibility.

METHODSPatients with hepatitis C (n=300, group A) and healthy subjects (n=520, group B) were genotyped and analysed for the repeat sequence of polymorphism of DC-SIGN and DC-SIGNR's exon 4 using PCR and DNA sequencing.

RESULTSThe distribution of genotypes and alleles in DC-SIGN's exon 4 in the two groups did not differ significantly (P > 0.05). The difference of allele frequency in DC-SIGNR's exon 4 between the two groups was also not significant (P > 0.05). However, 9/5 genotype distribution frequency of DC-SIGNR's exon 4 in patients with hepatitis C was significantly higher than that in the healthy subjects (P < 0.05).

CONCLUSIONThere is no significant correlation between the genetic polymorphism of DC-SIGN's exon 4 and HCV infection susceptibility. 9/5 genotype distribution frequency of DC-SIGNR's exon 4 in patients with hepatitis C is significantly higher and may be associated with HCV infection susceptibility.

OBJECTIVETo investigate the association of genetic polymorphism of dendritic cell-specific ICAM-grabbing nonintegrin (DC-SIGNR) and hepatitis C infection.

METHODSPatients with hepatitis C (n = 268) were genotyped and analysed for the repeat sequences polymorphism of DC-SIGNR using PCR and DNA sequencing. HCV virus load and HCV RNA genotypes were analyzed. Inter-group comparison was analyzed using LSD method.

RESULTSNo significant correlation was found between DC-SIGNR genotypes/ alleles and HCV RNA genotypes in patients. HCV-infected patients with 7-repeat (medium) alleles had lower HCV RNA levels compared to patients with 9-repeat (onger) alleles (P = 0.036). HCV-infected patients with 7/7 genotype had lower HCV RNA levels compared to patients with 9/7 genotype (P = 0.025). These findings suggest that optimal attachment of hepatitis C virions to DC-SIGNR may be associated with longer alleles.

CONCLUSIONThe fact that DC-SIGNR polymorphism might affect HCV loads supports the concept that DC-SIGNR contributes to HCV replication efficacy. There is no significant correlation between the genetic polymorphism of DC-SIGNR and HCV-RNA genotypes.
