Objective To explore the significance of Survivin and PTEN in gastric cancer development and correlation between Survivin and PTEN.Methods Immunohistochemical methods were applied to detect the expres.sion of Survivin and PTEN in 105 pathological specimens of gastric cancer, in comparison to that in 98 negative gastric mucosa tissues.Results The positive rate of Survivin expression was 82.9% (87/105) in tissue specimens of gastric cancer and 6.1% (6/98) in tissue specimens of non-gastric cancer;The difference between them was statistically sig nificant (P <0.01).The positive rates of PTEN expression were 34.3% (36/105) in tissue specimens of gastric canc-er and 99.0% (97/98) in tissue specimens of non-gastric cancer;The difference between them was statistically signifi-cant ( P <0.01).The expression of Survivin and PTEN in tissues of gastric cancer had nothing to do with the gender of patients ( P > 0.05 ) , but was correlated with the degree of tumor cell differentiation, depth of invasion, lymph node me-tastasis, distant organ metastasis and TNM staging(P <0.05).Analysis by Spearman showed that Survivin was nega-tively correlated with PTEN( r = -0.23 ,P < 0.05 ).Conclusion The incidence of gastric cancer was related to the abnormally high level of Survivin expression and absence of PTEN expression;The expression of Survivin and PTEN in tissues of gastric cancer was unrelated with the gender of patients, but related to the degree of tumor cell differentia-tion, depth of invasion,lymph node metastasis,distant organ metastasis and TNM staging.The expression of Survivin was negatively correlated with the expression of PTEN.

0.05). The cutaneous part occupied 2/3 of the entire upper lip height and the vermilion 1/3.The cutaneous part occupied more than 1/3 of the entire lower lip height.The chin occupied more than 60 percent of the entire mandibular height. Conclusion: The results of the study are consistent with the date of Farkas.
