Artificial intelligence technique in detection of early esophageal cancer.

Due to the rapid progression and poor prognosis of esophageal cancer (EC), the early detection and diagnosis of early EC are of great value for the prognosis improvement of patients. However, the endoscopic detection of early EC, especially Barrett's dysplasia or squamous epithelial dysplasia, is difficult. Therefore, the requirement for more efficient methods of detection and characterization of early EC has led to intensive research in the field of artificial intelligence (AI).

High HIF-1α expression predicts poor prognosis of patients with colon adenocarcinoma.

Hypoxia inducible factor 1 alpha subunit (HIF-1α) is induced in hypoxic conditions and plays a crucial role in the neoangiogenesis and metastasis of cancer. In this study, we aimed to evaluate the expression of HIF-1α in colon adenocarcinoma and to explore its clinicopathological characteristics and prognosis. A tissue microarray involving colon adenocarcinoma tissues and their corresponding paracancerous tissues from 92 patients was utilized to detect HIF-1α.

Suppressing growth and invasion of human hepatocellular carcinoma cells by celecoxib through inhibition of cyclooxygenase-2.

Biomarkers are lacking in hepatocellular carcinoma (HCC). Cyclooxygenase-2 (COX-2) and its metabolites play crucial roles in the process of inflammation-tumor transformation. This study was aimed to detect COX-2 expression in HCC tissues and evaluate the effects of a COX-2 inhibitor, celecoxib, on biological behaviors of HCC cell lines in vitro.

[Effect of Proton Pump Inhibitors on Severe Acute Pancreatitis--a Prospective Randomized Trial].

Objective: To evaluate the effect of proton pump inhibitors (PPIs) therapy on severe acute pancreatitis (SAP) patients.

Methods: Forty five patients with SAP recruited in our center from October 2015 to October 2016,were randomly assigned into two groups: convention group (C group,=21) and convention+esomeprazole group (C+E group,=24). C+E group received esomeprazole 40 mg/d intravenously for 1 week,whereas C group only received baseline treatment.

Carbohydrate antigen 125 and carcinoembryonic antigen in the differentiation of tuberculous peritonitis and peritonitis carcinomatosa.

Tumor markers could increase in both tuberculous peritonitis and peritonitis carcinomatosa, confusing the differentiation of these diseases. This study aimed to better understand the extent of elevation and diagnostic efficacies of carbohydrate antigen 125 (CA 125), carcinoembryonic antigen (CEA) and combinative use of them in tuberculous peritonitis and peritonitis carcinomatosa. Of 2998 patients reviewed, 101, 120 and 71 patients were assigned to TBP group (tuberculous peritonitis), non-OCA group (non-ovarian carcinoma-related peritonitis carcinomatosa) and OCA group (ovarian carcinoma-related peritonitis carcinomatosa), respectively.

Correlations between VEGF-A expression and prognosis in patients with gastric adenocarcinoma.

Angiogenesis induced by vascular endothelial growth factor A (VEGF-A) plays a critical role in tumor growth and metastasis. The study aimed to evaluate the expression of VEGF-A in gastric adenocarcinoma and investigate its correlations with tumor clinicopathological features and prognostic significance. VEGF-A expression was detected by immunohistochemistry on a tissue microarray containing 90 pairs of human gastric adenocarcinoma and paracancerous tissues.

Adjuvant celecoxib and lanreotide following transarterial chemoembolisation for unresectable hepatocellular carcinoma: a randomized pilot study.

Recurrence of hepatocellular carcinoma (HCC) after transarterial chemoembolisation (TACE) is common due to neoangiogenesis. Cyclooxygenase-2 inhibitors and somatostatin analogues were reported to inhibit tumour angiogenesis. The pilot randomized controlled trial was aimed to prospectively evaluate the protocol of TACE combined with celecoxib and lanreotide (TACE+C+L) in patients with unresectable and advanced HCC.

Celecoxib and octreotide synergistically ameliorate portal hypertension via inhibition of angiogenesis in cirrhotic rats.

Abnormal angiogenesis is critical for portal hypertension in cirrhosis. Except for etiological treatment, no efficient medication or regime has been explored to treat the early stage of cirrhosis when angiogenesis is initiated or overwhelming. In this study, we explored an anti-angiogenesis effort through non-cytotoxic drugs octreotide and celecoxib to treat early stage of cirrhotic portal hypertension in an animal model.

Inhibition of cyclooxygenase-2 alleviates liver cirrhosis via improvement of the dysfunctional gut-liver axis in rats.

Inflammatory transport through the gut-liver axis may facilitate liver cirrhosis. Cyclooxygenase-2 (COX-2) has been considered as one of the important molecules that regulates intestinal epithelial barrier function. This study was aimed to test the hypothesis that inhibition of COX-2 by celecoxib might alleviate liver cirrhosis via reduction of intestinal inflammatory transport in thiacetamide (TAA) rat model.

Targeting inhibition of extracellular signal-regulated kinase kinase pathway with AZD6244 (ARRY-142886) suppresses growth and angiogenesis of gastric cancer.

AZD6244 (ARRY-142886), a highly selective MAPK-ERK kinase inhibitor, has shown excellent clinical efficacy in many tumors. However, the anti-tumor and anti-angiogenesis efficacy of AZD6244 on gastric cancer has not been well characterized. In this study, high p-ERK expression was associated with advanced TNM stage, increased lymphovascular invasion and poor survival.
