Development and verification of prognostic nomogram for ampullary carcinoma based on the SEER database.

Background: Ampullary carcinoma (AC) is a rare cancer of the digestive system that occurs in the ampulla at the junction of the bile duct and pancreatic duct. However, there is a lack of predictive models for overall survival (OS) and disease -specific survival (DSS) in AC. This study aimed to develop a prognostic nomogram for patients with AC using data from the Surveillance, Epidemiology, and End Results Program (SEER) database.

Association between gallstone and cardio-cerebrovascular disease: Systematic review and meta-analysis.

Increasing evidence connects gallstone disease (GD) to cardio-cerebrovascular disease (CVD). The aim of the present systematic review and meta-analysis was to determine whether and to what extent an association between GD and CVD existed. PubMed, EMBASE and the Cochrane Library were systemically searched up to March 3rd, 2018.

Significance of hepatitis B virus surface antigen, hepatitis C virus expression in hepatocellular carcinoma and pericarcinomatous tissues.

Aim: To investigate the correlation between hepatitis B virus surface antigen (HBsAg), hepatitis C virus (HCV) expression in hepatocellular carcinoma (HCC), the HAI score of the noncancerous region of the liver and the serum Alpha fetoprotein (AFP) level.

Methods: The patterns of HBsAg and HCV in 100 cases of HCC and their surrounding liver tissues were studied on paraffin-embedded sections with immuno-histochemistry, the histological status was determined by one pathologist and one surgeon simultaneously using the hepatitis activity index (HAI) score, and AFP was detected by radioimmunity. The study included 100 consecutive patients who underwent curative resection for HCC.

[Study on the correlations between HBsAg and hepatitis C virus expression as well as fibrotic staging in hepatocellular carcinoma and pericarcinomatous tissues].

Objective: To study the correlation between hepatitis B virus surface antigen (HBsAg) and hepatitis C virus (HCV) expression as well as fibrosis staging in hepatocellular carcinoma (HCC) and pericarcinomatous tissues.

Methods: The patterns of HBsAg and HCV in 100 cases of HCC and their surrounding liver tissues were studied on paraffin-embeded sections with immunohistochemistry technique, and liver tissues were also staged.

Results: HBV, HCV virus infection were positively correlated with the fibrotic staging (r(s) = 0.

[Correlation between HBsAg, HCV expression in cancerous and pericancer tissues of hepatocellular carcinoma and liver fibrosis markers in serum].

Objective: To study the correlation between HBsAg and HCV in hepatocellular carcinoma (HCC) pericarcinomatous tissues and serum liver fibrosis markers.

Methods: The patterns of HBsAg and HCV in 100 cases of HCC and their surrounding liver tissues were studied with paraffin sections using immunohistochemistry techniques. Hyaluronic acid (HA), procollagen III peptide (PIIIP), collagen IV (CIV), and laminin (LN) were detected by radioimmunoassay.
