Objective To study the content of IL-8 in the peripheral blood and the expression of its mRNA in liver biopsy tissue of patients with hepatocirrhosis.Methods The patients with typical hepatocirrhosis resulted from HBV infection were selected.The IL-8 concentrations in peripheral blood of the Datients were evaluated with ELISA.The content of IL-8 mRNA in liver biopsy was measured by real-time PCR.The level of IL-8 mRNA was surrogated by lg cDNA/lg GAPDH.Reslllts The levels of IL-8 in the serum and its mRNA in hepatic tissue of patients with hepatoeirrhosis were(43 1.39±97.39)μg/L and 1.3647±0.2203,respectively,which were significantly higher than those of control group.MoreoCer,the levels of IL-8 in the serum and IL-8 mRNA in hepatic tissue of patients with positive HBV-DNA were (502.43-4-102.24)μg/L and 1.51424±0.2245,respectively,and both ofwhich were higher than those of patients without HBV-DNA replication(P<0.0l,P<0.05).And the levels of IL-8 in the selqlm and its mRNA in hepatic tissue of patients with higher ALT.AST also increased significantly.compared with those in control group(P<0.01).Conclusion The levels of IL-8 in the peripheral blood and the IL-8 mRNA in liver biopsy tissue of patients with hepatocirrhosis increase.which are related to the degree of HBV-DNA replication and the damage of hepatocytes.The IL-8 plays a key role in local inflammatory infihration of liver and the progression of post-hepatitis cirrhosis.

Objective:To study the expression of IP-10 and its mRNA in liver biopsy of patients with cirrhosis.Methods:The typical patients with cirrhosis after HBV infection were selected,and their serum IP-10 concentrations were evaluated with ELISA,the content of IP-10 mRNA in liver biopsy was measured by Real-time PCR.The level of IP-10 mRNA was represented by lg cDNA/lg GAPDH.The expression of IP-10 in liver biopsy tissue was detected by SP immunohistochemistry stain.Results:The levels of IP-10 in serum and its mRNA in liver biopsy of patients with cirrhosis were (299.3?77.2)pg/ml and (0.856 3?0.150 6),lg cDNA/lg GAPDH respectively,which were significantly higher than those of control groups(P

Objective:To analyze the epidemiological and clinical characteristics of patients with imported corona virus disease 2019 (COVID-19) in Beijing City.Methods:A case-control study was performed to retrospectively analyze 69 cases of imported COVID-19 from abroad and 147 cases of domestic confirmed COVID-19 from China as a control group from January 20 to March 20, 2020 admitted to Beijing Ditan Hospital, Capital Medical University.The epidemiological and clinical characteristics were compared.Statistical analysis were performed by t test, Mann-Whitney U test, chi-square test and Fisher exact test. Results:The main sources of the cases in the import group were from the United Kingdom, Italy, Spain and other European countries, with 44.9%(31/69) of the overseas students entering the country by air. The age of the imported group (27(21, 40) years) was lower than the domestic group (43 (32, 59)years), the difference between the two groups was statistically significant ( U=2 828.500, P<0.01). Compared with the domestic group, the proportion of cases with contact history of confirmed cases in the imported group was lower (30.4%(21/69) vs 68.0%(100/147)), the interval between onset and admission ≤seven days was higher (81.2%(56/69) vs 66.0%(97/147)), the proportion of cases with underlying diseases was lower (21.7%(15/69) vs 44.2%(65/147)). The differences between the two groups were all statistically significant ( χ2=26.935, 5.233 and 10.175, respectively, all P<0.05). The proportion of mild cases in the imported group was higher than that in the domestic group (42.0%(29/69) vs 10.9%(16/147)). Seventeen cases with olfactory abnormality and 12 cases with taste abnormality were found in the imported group, while no olfactory and taste abnormality was found in the domestic group. The proportions of fever, weakness, muscle soreness and dyspnea were all lower than those of the domestic group, the differences between the two groups were all statistically significant ( χ2=13.851, 8.118, 9.730 and 16.255, respectively, all P<0.01). The proportions of cases with decreased lymphocyte absolute numbers (37.7%(26/69) vs 67.3%(99/147)) and increased C reactive protein level (15.9%(11/69) vs 51.8%(72/139)) were both lower than the domestic group, and the differences between the two groups were both statistically significant ( χ2=18.015 and 24.722, respectively, both P<0.01). The proportions of cases with ground glass shadow and consolidation of chest computed tomography were lower than those of the domestic group and the differences between the two groups were all statistically significant ( χ2=11.961 and 5.099, respectively, all P<0.05). In terms of complications, the proportions of cases with acute respiratory distress syndrome and acute myocardial injury were lower (2.9%(2/69) vs 10.9%(16/147) and 4.3%(3/69) vs 14.0%(16/114), respectively), and there were statistically significant differences between the two groups ( χ2=4.017 and 4.335, respectively, both P<0.05). There were no cases received mechanical ventilation and extracorporeal membrane oxygenation in the imported group, and the proportions of patients received oxygen therapy and antibiotic treatment were significantly lower than those in the domestic group (13.0%(9/69) vs 26.5%(39/147) and 13.0%(9/69) vs 39.5%(58/147), respectively) and the differences between the two groups were statistically significant ( χ2=4.942 and 15.797, respectively, both P<0.05). Conclusions:The majority of imported COVID-19 cases are mainly from European countries, mostly young and middle-aged, and mostly mild and ordinary types.The symptoms of olfactory and taste abnormality are found for the first time.
