2012, 30(1): 25-28,31. doi: 10.3969/j.issn.1006-0111.2012.01.006
Abstract:
Objective To investigate the protect effect and mechanism of total polysaccharides (TPC) isolated from 50% ethanol extract of Wuzi-Yanzong pill (WZ) against chronic alcohol-induced injury in Rat . Methods The effect of TPC on chronic ethanol hepatotoxicity was investigated in modified Lieber-DeCarli rat model. Hepatocellular damage indicator (Serum ALT, AST) and histopathological examination of liver in rat were evaluated. MDA content, SOD activity and GSH content in liver were measured. TNF-α content and TNF-α mRNA expression were determined. Results TPC protected against chronic ethanol-induced hepatotoxicity in rat, as evidenced by decreased plasma transaminases activities and signally improve the liver pathological changes induced by alcohol. TPC significantly inhibited the increase of MDA content, improved SOD activity and prevented GSH depletion. TPC significantly alleviated hepatic TNF-α production and decreased the expression of TNF-α mRNA. Conclusion TPC possessed potent hepatoprotective activities in chronic alcohol-induced injury rat model. The suppressive effect of TPC on chronic alcohol induced liver injury might be attributed to the antioxidant action and suppress TNF-α expression at protein and gene level.

Abstract:
Objective To Sum up the situation of using antibiotics in intracoronary coronary stenting, and normalize the usage criterion and reinforce the management of antibiotics. Methods Retrospective survey method was used. 206 cases of patients who underwent cardiac intervention surgery between Jan., 2011 to May, 2011 were randomly selected for investigating and analyzing the usage of antibiotics. Results In the 260 cases, only 7 cases received no antibacterial treatment, while other 199 cases (96.6%) received prophylactic antibacterial treatment. The cephamycins was the predominant prophylactic antibiotics with the utility rate of 60.86%; the usage rate of first-generation and second-generation cephalosporins were 16.21% and 13.04% respectively; the usage rate of quinolone was 5.53%. All cases were medicated after surgery. The duration of prophylactic therapy spanned from 1d to 12 d, and the average antibacterial usage period was 3 d. Conclution The outstanding problems in prophylactic usage of antibiotics were the improper choice for the antibiotics, the improper choice for the medicinal usage occasion and the prolonged postoperative usage of antibiotics. It was urgent to intensify physicians' consciousness about rational use of antibiotics in intracoronary coronary stenting during perioperative period.
