ABSTRACT
Objective To detect patients with cancer of the stomach cancer tissue and serum Periostin protein expression of the situation,the preliminary explore its clinical significance.Methods Selected 60 cases of our hospital diagnosed as gastric carcinoma patients with carcinoma tissue samples,tissue adjacent to carcinoma specimens and serum,and choose 60 cases of healthy check-up serum specimens at the same time.Classified all patients according to clinical classification factors,inclu-ding age,sex,TNM stage,degree of infiltration,lymph node metastasis and pathological grading,immunohistochemical meth-od determination of Periostin in gastric cancer and adjacent tissue protein expression,enzyme-linked immunoassay detection in patients with gastric cancer patients and normal serum Periostin protein content.Results The method of ELISA to detect gastric cancer patients serum Periostin protein level was 46.76.4 ng/ml,and healthy crowd Periostin protein levels was 23.1 ±4.5 ng/ml,statistically significant difference (t= 7.34,P<0.05).Immunohistochemical methods showed that Periostin in patients with cancer of the stomach cancer tissue protein positive rate was (73.2±5.4)%,positive rate of (33.4±6.5)%in the tissue adjacent to carcinoma,statistically significant difference (t=8.52,P<0.05).Ⅲ~Ⅳ period patients serum Periostin protein level was 64.9±6.3 ng/ml,Ⅰ~Ⅱ period patients serum Periostin protein level was 41.6±4.1 ng/ml, statistically significant difference (t=9.17,P< 0.05).Periostin protein inⅢ~Ⅳ positive rate was 67.8% in patients with carcinoma tissue,Ⅰ~ phase Ⅱ positive rate was 52.9%,statistically significant difference (t=9.64,P<0.05).According to infiltrate the classificationT3,T4 patients serum Periostin protein level was 61.9±6.6 ng/ml,T1 and T2 patients serum Periostin protein level was 44.6±3.7 ng/ml,statistically significant difference (t=8.24,P<0.05).Periostin protein in T3 and T4 positive rate was 6 6.2% in patients with carcinoma tissue,T1 and T2 positive rate was 5 1.4%,statistically signifi-cant difference (t=7.58,P<0.05).Lymph node metastasis patients serum Periostin protein level was 65.2±4.3 ng/ml, without metastasis in patients with serum Periostin protein level was 42.6±3.2 ng/ml,statistically significant difference (t=7.63,P<0.05).Periostin protein in the tissue of carcinoma patients with lymph node metastasis group positive rate was 60.8%,no transfer of positive rate was 37.5%,statistically significant difference (t=8.56,P<0.05).Conclusion Periostin protein expression in patients with gastric cancer tissue and serum was significantly higher than that of healthy people,and to a certain extent is proportional to the illness,Periostin protein is a predictable stomach occurrence,lesion degree of poten-tial biological indicators.
