In the fifth, the seventh and the ninth week,rats in three groups were selected randomly to collect plasma and liver tissues. The levels of ET, AgII, PGI2, CGRP and GG were assayed by radioimmunoassay (RIA). The liver fibrosis was observed with silver staining.RESULTS: The hepatic fibrosis was developed with the increase of the injection frequency of CCl4. The ET, AgII, PGI2, CGRP The histological examination showed that the degrees of the rats liver fibrosis in group E were lower than those in group C.CONCLUSION: The transmitters ET, AgII, PGI2, CGRP and GG play a significant role in the rat hepatic fibrosis induced by CCl4. IL-10 has the antagonistic action on these transmitters and can relieve the degree of the liver fibrosis.展开更多

The positive signals of IGF-1 and IGF-1R were observed more frequently (P<0.01) in the CCl4-treated group (92.0 % and 90.0 %) compared to those in the control group. The positive signals decreased significantly (P<0.05) in IL-10-treated group. The responses in IGF-1 and IGF-1R expression correlated with the time of IL-10 treatment.CONCLUSION: The expression of IGF-1 and IGF-1R immunoreactivities in liver tissue seems to be up-regulated during development of hepatic fibrosis induced by CC14, and exogenic IL-10 inhibits the responses.展开更多

The acquirement of baseline data of antibiotic prescribing is the basis of developing intervention strategies on inappropriate antimicrobial prescriptions. Few studies show clearly the pattern and detailed information on classes of antibiotics and distribution of indications of antibiotic prescriptions in children in China. This study aims to assess the antibiotic prescribing patterns among children and neonates hospitalized in 18 hospitals in China. Methods A 24-hour point prevalence survey on antimicrobial prescribing was conducted in hospitalized neonates and chil-dren in China from December 1st, 2016 to February 28th, 2017. Information on the antibiotic use of patients under 18 years of age who were administered one or more on-going antibiotics in the selected wards over a 24-hour period was collected. These data were submitted to the GARPEC (Global Antimicrobial Resistance, Prescribing and Efficacy in Children and Neonates) web-based application ( https ://pidrg -datab ase.sgul.ac.uk/redca p/ ). For statistical analysis, Microsoft Excel 2007 and SPSS 22.0 were used. Results The antibiotic data were collected in 35 wards in 18 hospitals from 9 provinces. In total, 67.76% (975/1439) of the patients (n = 1439) were given at least one antibiotic, including 58.1% (173/298) of neonates (n = 298) and 70.3% (802/1141) of children (n = 1141). In neonates, the three most frequently prescribed antibiotics were third-generation cephalosporins (41.7%), penicillins plus enzyme inhibitor (23.8%), and carbapenems (11.2%). In children, the three most frequently pre-scribed antibiotics were third-generation cephalosporins (35.5%), macrolides (23.2%), and penicillins plus enzyme inhibi-tors (15.9%). The most common indication for antibiotics was proven or probable bacterial lower respiratory tract infection (30.9% 展开更多
