Objective: To investigate the effect of Scutellaria barbata D. Don on the expression of ADAM10 (a disintegrin and metalloproteinase 10) in primary liver cancer tissues in rats. Methods: Total of 120 Wistar rats were randomly divided into four groups: normal, model, matrine and Scutellaria barbata D. Don groups. The model of rat bearing primary liver cancer was induced by diethylnitrosamine. The rats in the matrine group and Scutellaria barbata D. Don group were fed with matrine and Scutellaria barbata D. Don powder, respectively. The rats in the normal group and model group were fed with 0.9% sodium chloride solution. The number of hepatocellular carcinoma nodules was calculated, and the tumor growth inhibition rate was also calculated. The pathologic changes of hepatic tissues in rats of each group were observed by hematoxylin and eosin staining. The expressions of ADAM10 in liver cancer tissues in these four groups were determined by immunohistochemistry and Western boltting. Results: The number of hepatocellular carcinoma nodules of the matrine group and Scutellaria barbata D. Don group was less than that of the model group (P < 0.05) with the appearance of apoptotic bodies. The tumor growth inhibition rate of Scutellaria barbata D. Don group was higher than that of the matrine group (P < 0.05). The positive expression rate and the expression level of ADAM10 in liver cancer tissues of the model group were significantly higher than those of the normal group (P < 0.05). The positive expression rate and the expression level of ADAM10 in liver cancer tissues of matrine group and Scutellaria barbata D. Don group were lower than those of the model group (P < 0.05). The positive expression rate and the expression level of ADAM10 in liver cancer tissues of Scutellaria barbata D. Don group were lower than those of matrine group (P < 0.05). Conclusion: Scutellaria barbata D. Don may inhibit the growth of primary liver cancer in rats through down-regulating the expression of ADAM10. Copyright © 2013 by TUMOR.

[Objective]To explore the allograft,as a substitute for autograft,whether can be used to repair the defect of the tendon and restore the stability of joint and the dynamic biomechanical changes of allograft after transplantation.[Method]Deep-frozen allogeneic achilles tendons of rabbits were used as treatment group,and autogenous ones as control.The achilles tendon defects of back limbs were repaired by allograft and autograft separately.The macroscopic,microscopic observation and biomechanical test were performed on both of them before transplantation and in 2,4 and 8 weeks after transplantation.[Result]It was showed that there were no differences in macroscopy,microscopy and mechanical strength between allograft and autograft both before and after transplantation.They may have experienced the similar healing course.The mechanical strength of allograft(except failure strain) was reduced significantly after transplantation.But it had a rising trend with time passing,although it was fairly low in 8 weeks compared with the normal such as maximum load.[Conclusion]The results demonstrate that the deep-frozen allograft can substitute for autograft in repairing the tendon defect,and because of the weakness of allograft after transplantation,it needs appropriate protection to prevent failure by excessive strain in early stage.

Objective To investigate the relationship between preoperative anemia,low albumin,low body mass index and the prognosis of advanced gastric cancer.Methods Three hundred and seventeen patients diagnosed with advanced gastric cancer as well as complete clinical pathology data from January 2006 to January 2008 were retrospectively analyzed.The clinical pathologic factors including age,gender,tumor size,type of Borrmann,hemoglobin,serum albumin,body mass index,type of histology,blood vessels and lymphatic invasion,infiltration depth,lymph nodes metastasis.The single factor and multiple factors were analyzed.Results Tumor size,type of Borrmann,hemoglobin,serum albumin,body mass index,type of histology,blood vessels and lymphatic invasion,infiltration depth and lymph node metastasis were identified as influencing factors of the prognosis,while independent factors associated with the prognosis of gastric cancer were serum albumin (OR =1.546,95％ CI:1.069-2.237),infiltration depth (OR =1.933,95％ CI:1.182-3.162) and lymph nodes metastasis (OR =1.586,95％ CI:1.358-1.853).Conclusion Anemia and low body mass index are the influence factors but not the independent factors in the prognosis of gastric cancer,while low albumin concentration is the independent factor in the prognosis of gastric cancer.

Objective To determine the impact of body mass index(BMI)on clinical outcomes in patients underwent coronary revascularization.Methods The DESIRE-plus(Drug-Eluting Stent Impact on Revascularization-plus)was a single-center registry study of coronary revascularization in our institution between 1 July 2004 and 30 September 2005.We analyzed patients with complete data of BMI from the DESIRE-plus trial,grouped by BMI(low BMI group:BMI

Objective To assess the influence of hemoglobin(Hb) concentrations on long-term mortality in male patients after percutaneous coronary interventions(PCI).Methods The DESIRE-2(The Second Drug-Eluting Stent Impact on Revascularization Registry) is a single-center registry of 6005 patients undergoing coronary revascularization from Jul 2003 to Sep 2005.There were a total of 2 641 PCI male patients without previous treatment with thrombolytic substances and end-stage renal failure before interventional procedure and the baseline hemoglobin data were available.Depending on their baseline hemoglobin,patients were divided in quintiles.We compared the clinical features and prognosis of all these patients.Results Significant differences were found between the quintiles regarding age(P
