Objective To investigate the clinical significance of circulating tumor cells (CTCs) in pa-tients with small-cell lung cancer patients (SCLC). Methods 42 SCLC patients, 10 patients with benign lung disease(hospitalized from June 2012 to June 2013), and 10 healthy volunteers from the First Affiliated Hospital of Shihezi University Medical College were studied and their clinical information was collected. Negative immuno-magnetic separation method and immunocytochemistry method were applied to collect the Pan-CK +/CD45 - of CTCs, in order to analyze the relationship between CTCs and clinical manifestation. Results CTCs were found in 32 cases of SCLC group, with a positive rate of 76.19%. CTCs was not found in peripheral blood in control group. Difference in the two groups is significant (P = 0.000). The presence of CTCs was correlated positively with the patients′ PS score , clinical stage , M stage , the number of metastatic sites , NSE value and LDH value (P < 0.05). Conclusion The CTCs number is correlated with patients′ PS score, clinical stage, M stage, the number of metastatic sites, NSE value and LDH value, respectively. CTCs detection is useful for more accurate risk assessment of patients.

Objective To investigate the relationship between the presence of circulating tumor cells (CTC) and the clinicopatho-logic characteristics of primary lung cancer patients .Methods Samples of peripheral blood(7 .5 mL) from 65 cases of patients with lung cancer(lung cancer group) and 10 cases of patients with lung benign diseases and 10 healthy volunteers (control group) ,and then those CTC were enriched by negative immunomagnetic separation with anti-CD45 antibody and then dectected by immunocyto-chemistry with anti-pan-cytokeratin antibody .The relationship between the positive rate of CTC and clinicopathologic characteristics of lung cancer patients were analyzed .Results The positive rate of CTC in lung cancer patients was 69 .23% (45/65) ,while CTC was not detected in any patients with lung benign disease or healthy volunteers .The positive rate of CTC in patients at TNM stageⅠ - Ⅱ ,Ⅲ and Ⅳ was 23 .08% (3/13) ,50 .00% (6/12) and 90 .00% (36/40) ,respectively .There was significant difference in posi-tive rate of CTC between patients at different TNM stages (P= 0 .000) .The positive rate of CTC in metastatic (stage M1 ) lung cancer patients(83 .33% ,35/42) was significantly higher than that in non-metastatic(stage M0 ) lung cancer patients(43 .48% ,10/23)(P=0 .002) .With the increasing number(0 ,1 ,2 ,3) of metastatic sites ,the positive rate of CTC increased (53 .48% ,83 .33% , 87 .50% ,75 .00% ) ,and there was significant difference in different positive rates of CTC (P=0 .024) .There was statistically sig-nificant difference in the positive rate of CTC between Cyfra 21-1 normal group(53 .33% ,16/30) and high value group(92 .00% ,23/25)(P=0 .021) ,the same with LDH normal group(55 .00% ,22/40) and high value group(82 .86% ,29/35)(P=0 .004) .Conclu-sion CTC were presented in some lung cancer patients .The presence of CTC in peripheral blood is correlated positively with the patients′clinical stage ,M stage ,the number of metastatic sites ,Cyfra21-1 value and LDH value .CTC detection is useful for more accurate risk assessment of patients with lung cancer .

Objective To investigate the effect of estrogen receptor ?(ER-?)on the formation of mice endometriosis.Methods Endometriosis animal model was established with 30 ER-? knockout(?ERKO)mice and 22 ER-? non-knockout(?ER)mice.All the mice were divided into three groups:intact group(?ERKO 10 and ?ER 8),ovariectomy group(?ERKO 10 and ?ER 7)and ovariectomy + estradiol treatment group(?ERKO 10 and ?ER 7).The endometriotic grafts were taken out from all the mice 2 weeks after operation,and the weight,histological structure and the expression of MMP-9 in the grafts were analyzed and compared between ?ERKO and ?ER mice.Results The endometriotic grafts were significantly heavier 2 weeks after transplantation than that before transplantation in intact group(P0.05).In addition,no significant differences were found between the ?ERKO and the ?ER mice in endometriotic grafts' weight,the histopathologic structure and the expression of MMP-9.Conclusion ER-? may throw few influence on the formation of endometriosis.

This study is to investigate the effects of ubenimex on tumor cell invasion and apoptosis, dose relationship and mechanism. Immunofluorescence staining was performed to detect the expression of CD13 in HT-1080 cells. MTT assay was used to analyze the effect of ubenimex on cell proliferation. Annexin V-EGFP/PI was used to detect apoptotic cells by flow cytometry. Cell cycle was analyzed using flow cytometry. Ala-pNA was used as substrate to evaluate the effect of ubenimex on the aminopeptidase activity. Transwell assay was used to analyze the effect of ubenimex on cell invasion and migration ability. Western blotting was used to detect the expression level of CD13. MMP activity was analyzed using gelatin zymography. The results showed that ubenimex at high concentration inhibited the proliferation of HT-1080 cells (IC50: 3.8 mg x mL(-1)), and induced cell apoptosis. Cell cycle was blocked at G1 phase. Ubenimex at low concentration inhibited the aminopeptidase activity of HT-1080 cells (IC50: 8.3 microg x mL(-1)) and inhibited cell invasion, but it had no effects on the cell migration and proliferation. Ubenimex had no effects on CD13 expression and MMP activity. In conclusion, ubenimex at low concentration can inhibit the invasion ability of tumor cells by directly inhibiting the aminopeptidase activity; ubenimex at high concentration can inhibit the proliferation of tumor cells and induce cell apoptosis by a CD13-independent pathway.
