To assess the expression of peripheral blood CD62P in patients with non-small cell lung cancer and its clinical significance, peripheral blood CD62P content in 75 patients with lung cancer was detected by immune-flow-cytometry. Among them 45 patients with lung cancer were subjected to comparison of the CD62P contents between pre-operation and post-operation, and comparison with those of 30 normal donors. The results showed that peripheral blood CD62P content in patients with lung cancer was significantly higher than that in normal con-trols(P

Objective To study the expressions of MMP-2 and TIMP-2 in pancreatic carcinoma and their relationship with tumor invasion, local metastasis and prognosis of the carcinoma. Methods The expressions of MMP-2 and TIMP-2 were examined in 32 patients with pancreatic carcinomas by S-P immunohistochemical technique and the correlation with pathological tumor parameters were analyzed. Survival analysis was made by using the Kaplan-Meier method. Results The positive rates of MMP-2, TIMP-2 in 32 patients with pancreatic carcinoma were 56.25% and 75.00%, which were significantly higher than those of the controls(P＜0.05). Expressions of MMP-2 and TIMP-2 were independent of sex, age, histological grading and type, but well correlated with the lymph node metastasis and TNM clinical staging(Ⅰ and Ⅲ, Ⅱ and Ⅲ). There was a significant association between MMP-2, TIMP-2 and prognosis in pancreatic carcinoma. Conclusion MMP-2 and TIMP-2 might be useful markers for biological aggressiveness of this malignancy and might contribute to the invasive properties of pancreatic carcinoma, which can be used to evaluate the prognosis of patients.

OBJECTIVE: To explore the laws of traditional Chinese medicine (TCM) syndromes in unstable angina, and to establish the preliminary diagnostic criteria for TCM syndromes. METHODS: Multi-center prospective research on TCM syndromes in 815 cases of unstable angina was done with the nonlinear dimension reduction by factor analysis. RESULTS: There were five extracted factors in factor analysis: F1, F2, F3, F4 and F5. F1 was yin deficiency of heart and kidney, F2 was deficiency of both heart and spleen, F3 was intermingled phlegm and blood stasis, F4 was qi deficiency and blood stasis, and F5 was yang deficiency and coagulated cold. Qi deficiency and blood stasis (F4) syndrome accounted for the maximum proportion. The diagnostic criteria for TCM syndromes were preliminarily and respectively established. CONCLUSION: Qi deficiency and blood stasis is the key factor of pathogenesis. The factor analysis can help us classify traditional Chinese medicine syndromes and establish the preliminary diagnostic criteria.
