RESUMO
<p><b>OBJECTIVE</b>To study the expression of stomatin-like protein-2 (SLP-2) in esophageal squamous cell carcinoma (ESCC), and analyze the correlation between SLP-2 expression and clinicopathological features.</p><p><b>METHODS</b>The expression of SLP-2 protein in ESCC tissues (18 and 220 cases respectively) was detected by Western blot and IHC. The association between SLP-2 expression and clinicopathological features was analyzed.</p><p><b>RESULTS</b>Compared with normal epithelium, 13 cases of ESCC tissues showed a higher expression of SLP-2 on the protein level (72.2%, 13/18). IHC analysis on tissue microarray revealed that the expression rate of SLP-2 protein in ESCC was 54.1% and in normal esophageal mucosa was 3.6%, showing a significant difference (P < 0.001). SLP-2 high-level expression correlates with the extent of ESCC invasion (P = 0.033), but not with other clinicopathologic characteristics (P > 0.05).</p><p><b>CONCLUSION</b>SLP-2 as a novel cancer-related gene may play an important role in tumorigenesis of ESCC. The overexpression of SLP-2 may be closely associated with the invasion of esophageal cancer.</p>

<p><b>OBJECTIVE</b>To investigate the influence of Shenfu injection on the hemodynamic indexes of myocardial ischemic dogs and blood pressure of dogs and rats.</p><p><b>METHOD</b>Myocardial ischemic model was made and hypotension in the dogs was induced with ligating left front descending limb coronary artery method, and secondary hypertension by narrowing nephridium artery of rats, Shenfu injection was administered with 5, 10 mL.kg-1 to the above dogs and rats separately to investigate the influence of it on the hemodynamic indexes of myocardial ischemic dogs and blood pressure of rats.</p><p><b>RESULT AND CONCLUSION</b>Shenfu injection enhanced the capacity of myocardial work markedly; it augmented the myocardium contractility and cardiac output without raising the oxygen consume, and at the same time it returned normal the blood pressure in myocardial ischemic; but it had no effects on the normal blood pressure and secondary hypertension of rats.</p>
