Impact of operative and peri-operative factors on the long-term prognosis of primary liver cancer patients undergoing hepatectomy / 华中科技大学学报（医学）（英德文版）

This study examined the impact of the operative and peri-operative factors on the long-term prognosis of patients with primary liver cancer undergoing hepatectomy. A total of 222 patients with primary liver cancer who underwent hepatectomy were followed up from January 1986 to December 2010 at Chinese PLA General Hospital. The post-operative complication rate was 14.0% for all cases, 13.7% for hepatocellular carcinoma (HCC), 10.0% for cholangiocarcinoma. The 1-, 3-, 5- and 10-year overall survival rates in patients with primary liver cancer after resection were 76.6%, 57.6%, 41.4%, and 21.0%. The survival rates were significantly higher in the HCC group than in the cholangiocarcinoma group (P=0.000), in the non-anatomical resection group than in the anatomical resection group (P=0.005), in the female group than in the male group (P=0.002), in patients receiving no blood transfusion than in those who were given intra-operative blood transfusion (P=0.000), in patients whose intra-operative blood loss was less than 400 mL than in those who intra-operatively lost more than 400 mL (P=0.000). No significant difference was found in the survival rate between the HBsAg-positive group and the HBsAg-negative group (P=0.532). Our study showed that anatomical resection, blood loss and blood transfusion were predictors of poor survival after hepatectomy for primary liver cancer patients, and concomitant hepatitis B virus infection bore no relation with the post-resection survival.

An experimental research of neuroglobin expression changes and neural apoptosis after traumatic brain injury / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To study the expression changes of neuroglobin in rats with the model of diffuse traumatic brain injury and explore the relationship between the neuroglobin and neuron apoptosis in traumatic brain injury.</p><p><b>METHODS</b>The diffuse traumatic brain injury of rats was induced by the Marmarou's 'weight-drop' device. And the immunohistochemical technique was used to detect the expression changes of neuroglobin and neuron apoptosis in rat brain at different time points post-injury.</p><p><b>RESULTS</b>The expression of neuroglobin increased twice and reached peaks at 2 hours and 72 hours post-injury respectively. And the increased expression of neuroglobin from 30 minutes to 1 hour post-injury and from 48 hours to 72 hours post-injury accompanied with the decreased expression ratio of Bax to Bcl-2.</p><p><b>CONCLUSION</b>The increased expression of neuroglobin in traumatic brain injury informed us that neuroglobin had anti-apoptosis action in post-injury neuron. It could protect the neuron from traumatic stress and secondary ischemia and hypoxia insults during ultra-early and acute stages.</p>
