ABSTRACT
Objective To detect the expression of metallothionein-3 (MT-3)mRNA in human esophageal squamous cell carcinoma. Methods Five cell lines of human esophageal cancer,TE-1,TE-13,TTN,ECA-109 (cell lines of esophageal squamous cell carcinoma) and OE33 (cell lines of esophageal adenocarcinoma),were used in this study. RT-PCR was employed to detect the expression of MT-3 mRNA. Peripheral blood monouclear cells from normal subjects were served as controls. Results Sequencing of RT-PCR product certified the gene of MT-3 mRNA. It was revealed by gel electrophoresis that there was expression of MT-3 mRNA in each cell line. The relative expression of MT-3 mRNA was 0.230?0.023,0.516?0.020,0.140?0.009,0.176?0.015 and 0.085?0.011 in cell lines of TE-1,TE-13,TTN,ECA-109 and OE33,respectively,significantly lower than that in controls (0.762?0.026) (P
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the long-term outcomes of various antireflux procedures for gastroesophageal reflux disease (GERD).</p><p><b>METHODS</b>Between November 1988 and January 2004, 129 patients with GERD underwent antireflux procedures. Six kinds of antireflux procedures were performed including Nissen fundoplication, cardiac oblique invagination (COI) procedure, Belsey Mark IV, Toupet, Thal and Dor procedures. One hundred and sixteen patients were followed up. Esophageal manometry study was carried out in 95 patients preoperatively and 51 postoperatively. 24-hour esophageal pH monitoring were carried out in 56 patients preoperatively and 35 postoperatively. Esophagoscopy were performed in all patients before operation and 48 cases after operation.</p><p><b>RESULTS</b>Clinical symptom scores reduced significantly from 4.1 +/- 0.4 before surgery to 1.1 +/- 1.0 after surgery (t = 27.21, P < 0.01). The outcome of surgery showed excellent in 42 cases (36.2%), good in 60 (51.7%), fair in 7 (6.0%), poor in 7 (6.0%). The long-term follow-up showed excellent or good results in 87.9% of patients. There was no significant difference in Nissen fundoplication, COI procedure and Belsey Mark IV.</p><p><b>CONCLUSIONS</b>There are significant differences in symptom score, esophageal manometry, 24-hour esophageal pH monitoring and esophagoscopy pre- and post-operatively. There is no significant difference in Nissen fundoplication, COI procedure and Belsey Mark IV.</p>
