Objective: To investigated if cyclooxygenase-2 (COX-2) inhibitor celecoxib in combination with somatostatin (SST) analog octreotide is able to inhibit the metastasis of human gastric cancer (GC) in vivo.

Methods: Seventy five patients with GC were randomly divided into 3 equal groups: control group, taking no anti-tumor medicine before GC resection; celecoxib group, receiving celecoxib orally 200 mg/d for 7 days before surgery; and combination group, receiving celecoxib orally 200 mg/d and octreotide 100 microg injected subcutaneously for 7 days before operation. The resected specimens were studied for the expression of epithelial cadherin (E-Cad) and matrix metalloproteinase (MMP) by using immunohistochemical staining. MMP-2 and MMP-9 were also quantified with Western blotting. The GC cells from the resected gastric cancer specimens were isolated by immunomagnetic separation. Modified Boyden chamber membrane invasion culture system coated with Matrigel was used to observe the migration and invasion of the GC cells.

Results: The abnormal staining rates of E-Cad of GC tissue in the combination group and the celecoxib group were 28.0% and 44.0%, significantly lower than that in the control group (56.0%, both P < 0.05). The grey level of MMP-2 and MMP-9 in the combination and celecoxib groups were (99 +/- 20, 89 +/- 13) and (260 +/- 15, 180 +/- 13) respectively, both significantly lower than that of the control group [(314 +/- 11, 241 +/- 12), P < 0.05]. The number of GC cells that penetrated the membrane was (2.75 +/- 0.58)/10(3) cells in the combination group, (2.29 +/- 0.58)/10(3) cells, the migration rate of the combination group was lower by 38% compared with that of the control group (F = 6.44, P < 0.05).

Conclusion: The metastasis of human gastric carcinoma cells may be inhibited by the combinative treatment of celecoxib and octreotide.

Introduction: Post-stroke cognitive impairment (PSCI) and dementia affect short- and long-term outcome after stroke and can persist even after recover from a physical handicap. The process underlying PSCI is not yet fully understood. Transcranial Doppler ultrasound (TCD) is a feasible method to investigate cerebrovascular aging or dementia, through the pulsatility index (PI), the cerebrovascular reactivity (e.

Purpose: Our study evaluated skeletal muscle mass, function and quality among mild autonomous cortisol secretion (MACS) patients and non-functioning adrenal incidentaloma (NFAI) patients in comparison with the control group without adrenal mass.

Methods: 63 NFAI (49 female, 14 male) and 31 MACS (24 female, 7 male) patients were included in the study. As the control group, 44 patients (31 women, 13 men) who were known to have no radiological adrenal pathology on computed tomography or magnetic resonance imaging performed for other reasons were selected.

5-Fluorouracil (5-FU) is a chemotherapeutic that is used to treat solid tumors. However, 5-FU is associated with several side effects, including cardiotoxicity. Considering the importance of the intrinsic cardiac nervous system (ICNS) for the heart and that little is known about effects of 5-FU on this nervous system plexus, the purpose of the present study was to evaluate effects 5-FU at a low dose on the ICNS and oxidative and inflammatory effects in the heart in Wistar rats.

Background: Malnutrition is common with esophagogastric cancers and is associated with negative outcomes. We aimed to evaluate if immunonutrition during neoadjuvant treatment improves patient's health-related quality of life (HRQOL) and reduces postoperative morbidity and toxicities during neoadjuvant treatment.

Methods: A multicenter double-blind randomized controlled trial (RCT) was undertaken.
