Objective To evaluate expression of inducible nitric oxide synthase (iNOS) in human abdominal aortic aneurysm (AAA) and to identify its initiation in the oxidative vascular injury. Methods This study included 22 AAA patients and 10 cadaveric normal abdominal aorta. In situ hybridization and immunofluorenscent staining were used to localize iNOS messenger RNA (mRNA) and protein. Double staining with a combination of in situ hybridization and immunofluorenscent staining was used to simultaneously demonstrate iNOS mRNA expression and its cellular localization. The presence of end-product of oxidative injury induced by iNOS was indirectly assessed with immunofluorenscent staining by anti-nitrotyrosine antibody, its cellular localization were assessed by double immunofluorenscent staining. Results In situ hybridization and immunohistochemistry confirmed the presence of iNOS in media and adventitia of AAA in all 22 patients. Specific cell markers identified iNOS mRNA-positive cells were T and B lymphocytes, macrophages, and smooth muscle cells. Positive immunostaining for nitrotyrosine was present in macrophages and smooth muscle cells. Normal abdominal aorta demonstrated virtually no iNOS or nitrotyrosine expression. Conclusion Stimulated expression of iNOS is associated with degeneration of AAA in human beings leading to oxidative tissue and cellular injury in AAA.

ObjectiveTo probe the effect of the electroacupuncture on vascular dementia(VD) and content of arginine vasopressin(AVP) in brain of rats. Methods30 Sprague Dawley rats were made renal hypertension(RHR) by the kidney arteries pinched with silver clip.After 42 days, their bilateral common carotid arteries were blocked repeatedly to cause cerebral ischemia.The Hypertension Vascular Dementia model was made. Then they were divided into model group,electroacupuncture group and medicine group(Dihydroergotoxine,DHET) with 10 in each group. The course was 28 days. The ability of learning and memorizing was observed by water maze, and the content of AVP in brain was detected after treatment. ResultsThe latent period of the electroacupuncture group and medicine group was shorter than that of the model group(P<0.05-0.005), and that of the electroacupuncture group was shorter than medicine group(P<0.05-0.005). In frontal lobe, the contents of AVP in the electroacupuncture and medicine groups were higher than that of model group( P<0.01,P<0.05), and the electroacupuncture group was higher than medicine group in striatum (P<0.05). Conclusions It indicated that electroacupuncture therapy can promote the ability of learning and memorizing and enhance the content of AVP in the brain of VD rats. It's therapeutic effect is better than that of DHET.

OBJECTIVETo investigate the prognostic factors of hepatocellular carcinoma.
METHODSThe purpose of this study was to retrospectively analyze the surgical outcomes of hepatocellular carcinoma (HCC) in 832 patients who underwent hepatic resection between February 2002 and June 2010 in the Cancer Hospital of Chinese Academy of Medical Sciences. Post-resection prognostic factors were assessed using a univariate Kaplan-Meier analysis and a multivariate Cox proportional hazards model.
RESULTSThe overall 1-, 3- and 5-year survival rates were 92.0%, 70.2% and 53.6%, respectively. The disease free survival rates (DFS) were 90.2%, 61.5% and 40.5%, respectively. The univariate analysis showed that a better prognosis for overall survival (OS) was associated with asymptomatic presentation, small tumor, single lesion, high-grade histological differentiation, no vascular tumor embolus, negative serum alpha-fetoprotein (AFP), negative serum alkaline phosphatase (ALP), Child-Pugh class A, no ascites, no/mild cirrhosis, new surgical techniques, no blood transfusion, no regional lymph node metastasis, no major vascular invasion, and no extra-hepatic invasion. The multivariate analysis showed that asymptomatic presentation, small tumor, single lesion, no tumor embolus, negative serum alpha-fetoprotein (AFP), no regional lymph node metastasis, no major vascular invasion, no extra-hepatic invasion, no/mild cirrhosis, and surgical techniques are independent factors for a longer overall survival.
CONCLUSIONSThe prognosis of HCC after resection is influenced by a number of factors. Therefore, regularly screening and early diagnosis, applying surgical techniques to minimize the liver injury, and preventing the aggravation of cirrhosis are important measures to improve the overall survival of HCC patients. For those patients with high risk factors of recurrence, routine follow-up is one of the best methods to be recommended.
