ABSTRACT

0.05). The positive rates of PDGF and PDGFR in the HCC patients with the tumor emboli of portal vein and/or biliary duct were 76.9% and 76.9%, respectively, which were significantly higher than those(25.0% and 16.7%, respectively) in the ones without(P

ABSTRACT

Objective To investigate the relationship between the expression of PDGF and PDGFR and MVC in human gastric carcinoma. Methods The expression of PDGF and PDGFR in 57 cases with gastric carcinoma was detected by immunohistochemical method of avidin-biotin complex in formalin-fixed and routinely paraffin-embedded tissue sections. Results The expression of PDGF and PDGFR was significantly related to the infiltrative depth and regional lymph nodes metastasis of gastric carcinoma. The positive rates of PDGF and PDGFR in the cases with invasive depth over 2/3 muscular layer were 61 8% and 58 8% respectively, which were obviously higher than those(26 1%, 26 1%) in the ones with invasive depth less 2/3 muscular layer(P

ABSTRACT

Objective To investigate the earlier diagnostic methods and operative procedures of gastric remnant cancer. Methods Clinicopathologic data of 19 cases of gastric remnant cancer were retrospectively analysed,and the diagnostic value of the gastroscopy and barium meal was compared.Influencing the prognosis of gastric remnant cancer treated by different operations according to the situation seen during operation were observed. Results The diagnostic rate of gastroscopy and barium meal was 78.9% and 47.4%, respectively.All the 5 cases who underwent radical remnant gastrectomy sarvived≥3 years postoperatively.Two of the 3 cases who underwent palliative remnant gastrectomy survived 2 years and 1 alived 1.5 years postoperatively. In 6 cases of gastrojejunostomy, 4 cases died within half year, 2 cases died 12.5 and 14 months postoperatively. Conclusions The diagnostic value of gastroscopy takes advantage over barium meal examination. The patients who treated by radical remnant gastrectomy have better prognosis.

ABSTRACT

Objective To investigate the expressions of IL-8,MCP-1 and MIP-1? and their biological significance in pancreatic carcinoma and chronic pancreatitis, and investigate the relationships of their expressions in pancreatic cancer tissues.Methods Immunohistochemical method of avidin-biotin complex was used to examine surgically removed specimens from 51 cases of pancreatic carcinoma and 10 cases of chronic pancreatitis. Results The positive rates of expression and the scorings of IL-8,MCP-1,MIP-1? were significantly higher in pancreatic carcinoma than that in chronic pancreatitis(P
