ABSTRACT
<p><b>OBJECTIVE</b>To compare the clinical effect of 3S-type and P-loops digestive reconstruction after total gastrectomy for gastric cancer.</p><p><b>METHODS</b>From February 2005 to February 2009, 85 cases underwent total gastrectomy in The First Affiliated Hospital of Henan University of Science and Technology. Two types of digestive reconstruction were performed with 3S-type jejunum(n=46) and P-loops Roux-en-Y esophagojejunostomy(n=39). The postoperative complications, nutrition index and the quality of life at half a year after surgery were comparatively analyzed.</p><p><b>RESULTS</b>Two types of digestive reconstruction had no statistical differences in operative time, postoperative complications and mortality(P>0.05). Compared with P-loops Roux-en-Y esophagojejunostomy at 6 months after operation, 3S-type jejunum had a lower incidence in dumping syndrome[4.3% (2/46) vs. 10.3% (4/39), P<0.05] and reflux esophagitis [10.8% (5/46) vs. 33.3% (13/39), P<0.05]. 3S-type jejunum was superior to P-loops Roux-en-Y esophagojejunostomy in serum total protein(55.7±3.1 g/L vs 50.3±5.1 g/L, P<0.05), albumin(36.5±3.6 g/L vs. 31.6±4.4 g/L, P<0.05), hemoglobin(120.2±13.4 g/L vs. 110.4±23.0 g/L, P<0.05), and nutritional assessment index(73.2±4.8 vs. 56.0±6.3, P<0.05).</p><p><b>CONCLUSION</b>Reconstruction of stomach with 3S-type jejunum may be an effective way to prevent reflux esophagitis and dumping syndrome, and to improve the nutritional status and the quality of life.</p>

<p><b>OBJECTIVE</b>To investigate the role of first pass dynamic 16-slice spiral computed tomography in the evaluation of tumor angiogenesis in patients with non-small cell lung cancer (NSCLC) and to assess its importance in predicting pathologic characteristics.</p><p><b>METHODS</b>The first pass dynamic 16-slice spiral computed tomography was performed in 33 patients with NSCLC. Their peak heights (PH) were measured with dynamic evaluation software. Their angiogenesis were labelled by anti-CD34 monoclonal antibody. The first pass peak heights (PH) in 33 patients with NSCLC were compared with their microvessel densities (MVD) and their relationships were assessed by linear regression analysis.</p><p><b>RESULTS</b>Among the 33 patients with NSCLCs, the mean first pass PH and MVD of N1-2 were significantly higher than those at stage No (P < 0.01). The first pass PH of 33 NSCLC was correlated positively with MVDs. To differentiate stage N0 from stage N1-2 with 12 HU cutoff value of the first pass PH, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 88.0%, 75.0%, 84.8%, 91.7% and 66.7%, respectively.</p><p><b>CONCLUSION</b>The first pass dynamic contrast enhanced CT may be a predictor of tumor angiogenesis in patients with NSCLC and its pathologic characteristics, and may be helpful to improve the accuracy of lymph node staging with conventional CT.</p>

<p><b>OBJECTIVE</b>To investigate the expression and clinical significance of KiSS- 1 and E- cadherin in gastric cardia carcinoma and the correlation between the two proteins.</p><p><b>METHODS</b>The expression of KiSS- 1 and E- cadherin in 80 patients with gastric cardia carcinoma and 20 patients with normal gastric cardia epithelium was detected by immunohistochemical technique.</p><p><b>RESULTS</b>The expression of KiSS- 1 was negatively correlated with lymphatic metastasis and clinical stage (P < 0.05), but not correlated with the cancer differentiation (P < 0.05). The expression of E- cadherin was negatively correlated with lymphatic metastasis, clinical stage, and cancer differentiation (P < 0.05). Spearman test showed a positive correlation between KiSS- 1 and E- cadherin expression (r(s)=0.722, P < 0.05).</p><p><b>CONCLUSION</b>KiSS- 1 and E- cadherin may play important roles in inhibiting the invasion and metastasis of gastric cardia carcinoma.</p>
