RESUMO
Objective To detecte the expression of Apelin ( APLN) in prostate cancer tissue and to investi-gate its correlation with prognosis of prostate cancer .Methods Collect prostate cancer patients in Department of Urology of Huadu District People's Hospital for 2014 -2016 years in Guangzhou .The expression of APLN was detected by real-time fluorescence quantitative polymerase chain reaction ( qRT-PCR) in 20 prostate cancer tissues and 20 adjacent normal tissues.The difference between the two groups was compared .And 104 samples of primary prostate cancer and 28 samples of benign paracancerous tissues from the Taylor database were selected to analyze its relationship with the clinical features and prognosis of the patients .Results Compared with the benign paracancerous tissue(7.26 ±0.03),APLN was up-regulated in the prostate cancer tissue (7.62 ±0.42)(t=3.824,P<0.001). The up-regulation of APLN was associated with pathological stage (t=2.942,P=0.003),metastasis(t=3.022, P<0.001),Gleason score (t =2.399,P =0.031),the biochemical recurrence -free survival(t =2.533,P =0.001 ) ,and the biochemical recurrence -free survival of the patients with higher expression of APLN was shorter than that of the patients with lower expression of APLN(χ2 =6.268,P=0.012).Conclusion The abnormal expres-sion of APLN may be associated with tumor formation and malignant progression of prostate cancer .High expression of APLN can predict the biochemical recurrence -free survival in patients with prostate cancer .
RESUMO
<p><b>OBJECTIVE</b>To study the long-term curative effects of suture plus proximal gastric vagotomy (PGV) and suture plus triad-therapy (omeprazole, amoxycillin and flagyl taken orally) for the treatment of duodenal ulcer with acute perforation.</p><p><b>METHODS</b>Three hundred and twenty-nine patients with duodenal ulcer and acute perforation were treated with 2 different methods, respectively. Method A was suture plus PGV (group A, 153 cases), and method B was suture plus triad-therapy (group B, 176 cases). Follow-up was made by means of correspondence, outpatient reexamination and cooperation with local hospitals in 5 to 8 years after operation. The contents of follow-up included symptom acquisition (such as upper abdominal pain or distention, pyrosis, belch, acid regurgitation, vomiting, diarrhea and conditions of living or working), gastroscopy and Helicobacter pylori (HP) detection. The curative effects were evaluated by the Visick scale.</p><p><b>RESULTS</b>Three hundred and one patients were followed up (group A 142 and group B 159). According to the Visick scale, 97 (68.3%), 19 (13.4%), 13 (9.15%) and 13 (9.15%) patients in group A, and 31 (19.5%), 28 (17.6%), 24 (15.1%) and 76 (47.8%) in group B were classified as Visick I, II, III and IV respectively (Z = -9.818, P < 0.01). As for HP detection, there were 130 (91.5%) patients in group A and 94 (59.1%) in group B (chi(2) = 41.438, P < 0.01).</p><p><b>CONCLUSIONS</b>The long-term curative effects of suture plus PGV were superior to those of suture plus triad-therapy for duodenal ulcer with acute perforation although HP positive rate was higher in group A than in group B. HP infection is one of the etiological factors of duodenal ulcer. The increased excitability of the vagus nerve remains to play an important role in duodenal ulcer.</p>
