Objective To investigate expression level of sphingosine kinase 1 (SPHK1) and nuclear factor-κB (NF-κB) in non-small cell lung cancer (NSCLC) and their relationships with invasion, metastasis and prognosis of NSCLC. Meth-ods Ninety-three NSCLC specimens and paraneoplastic normal lung tissue from conventional surgery were confirmed by histology. Expression of SPHK1 and NF-κB were detected by Immunohistochemistry on paraffin sections. Primary antibody were Rabbit Anti-Human SPHK1 and Rabbit Anti-Human NF-κB p65, which were incubated 1 hour in water bath. The secondary antibody was HRP-Polymer anti Mouse IgG, which was incubated 20 minutes in water bath. Results SPHK1 ex-pression was positive in 96.8% (90/93) of NSCLC specimen which is higher than in paraneoplastic normal lung tissue in which the positive rate is 18.3%(17/93);NF-κB expression was positive in 89.2%(83/93) NSCLC which is higher than the in paraneoplastic normal lung tissue in which the positive rate is 12.9%(12/93). The expression of SPHK1 and NF-κB in NSCLC was positively correlated (r=0.464, P<0.01). TThe expression levels of SPHK1 and NF-κB p65 in NSCLC patients with were positively related to TNM staging and lymph node metastasis. SPHK1 expression and NF-κB p65 expression lev-el were higher in the deads than in survivals. There was no statistical significance in different expression intensity of SPHK 1 and NF-κB p65 in patients with NSCLC who had differences in gender, age, tumor size, tumor location, histological type. Survival analysis showed that survival time of patients of NSCLC with high expression of SPHK1 was shorter than those in the group with low SPHK1 expression, and the difference was statistically significant (χ2=14.025, P < 0.01). Conclusion In the process of NSCLC invasion and metastasis,SPHK1 may play an important role through NF-κB, and it can predict prognosis of NSCLC patient. Moreover, it will become a potential target for NSCLC target.

Objective To investigate the expressions of RhoB and E-cadherin in non-small-cell lung cancer (NSCLC), and their clinical significances thereof. Methods Immunohistochemical staining was applied to detect expres-sions of RhoB and E-cadherin in 116 samples of NSCLC (NSCLC group) and 116 samples of normal lung tissues (control group). Correlations of expressions of RhoB and E-cadherin to clinical pathological parameters and prognosis were analyzed in two groups. Results The expression intensities of RhoB and E-cadherin were significantly lower in NSCLC group than those in control group (57.76%vs 87.07%,54.31%vs 85.34%,P<0.01). There were significant differences in the expres-sion of RhoB between different pathological types, differentiation and lymph node metastasis in NSCLC group. There were significant differences in the expression of E-cadherin between different TNM stages, differentiation and lymph node metas-tasis in NSCLC group. The expression of RhoB was positively correlated with the expression of E-cadherin ( r=0.503,P<0.01). The 3-year survival rates were significantly higher in patients with high expression of RhoB (83.93%) than those in pa-tients with low expression of RhoB (40.00%, Log-rank χ2=18.992,P<0.01). The 3-year survival rates were significantly higher in patients with high expression of E-cadherin (85.11%) than those in patients with low expression of E-cadherin (44.93%, Log-rankχ2=16.680,P<0.01). Further multivariate analysis suggested that both lower expressions of RhoB and E-cadherin and lymph node metastasis were prognostic indicators for NSCLC (P<0.001). Conclusion The expressions of RhoB and E-cadherin showed a good correlation in NSCLC. Detecting the expression of RhoB combined with E-cadherin may give a clue on clinicopathological features and prognosis in patients with NSCLC.

Objective To investigate the expression levels and clinical significance of (forkhead box Q1) FOXQ1 and E-cadherin in esophageal squamous cell carcinoma (ESCC). Methods Expression levels of FOXQ1 and E-cadherin were in ESCC tissues (ESCC group, n=42) and adjacent normal esophageal tissues (control group, n=42) were detected using im?munohistochemistry. Correlations of FOXQ1 and E-cadherin expressions with clinical pathological parameters and progno?sis were analyzed between two groups. Results The expression level of FOXQ1 was significantly higher in ESCC group than that in control group(64.29% vs 28.57%,χ2=5.384,P<0.05). The expression level of E-cadherin was significantly lower in ESCC group than that incontrol group(52.38%vs 90.48%,χ2=7.691,P<0.05). There were significant differences in FOXQ1 expressions between different TNM stages and whether lymph node metastasis is involved within ESCC group. There were significant differences in expression of E-cadherin between different tumor differentiation, depth of invasion, TNM stage and whether lymph node metastasis is involved within ESCC group. The expression of FOXQ1 was negatively cor?related with E-cadherin in ESCC (r=-0.412, P<0.05). The 5-year survival rates were significantly lower with high expres?sion of FOXQ1 or with low expression of FOXQ1(18.52%vs 66.67%,χ2=9.737,P<0.05). The 5-year survival rates were significantly higher with high expression of E-cadherinor low expression of E-cadherin(59.09%vs 10.00%,χ2=10.996,P<0.05). A multivariate Cox's proportional hazard regression analysis indicated that high FOXQ1 expression, low E-cadherin expression and lymph node metastasis were independent prognostic factors for ESCC. Conclusion The expression of FOXQ1 and E-cadherin showed a good correlation with ESCC. And examining expressions of both FOXQ1 and E-cadherin in ESCC may have practical values in estimating the prognosis of ESCC and directing future treatment .

Objective:To investigate the expression of Gli-2 protein and nuclear proliferation marker Ki-67 in human thymic tu-mors, as well as its relationship with clinicopathological features and prognosis. Methods: Immunohistochemical staining was per-formed to determine the expressions of Gli-2 and Ki-67 in 64 thymic tumor cases, in which 9 were type A, 6 were type AB, 11 were type B1, 22 were type B2, and 16 were type C. Results:1) Positive expression rates of Gli-2 in types A, AB, B1, B2, and C thymomas were 1/9 (11.11%), 2/6 (33.33%), 2/11 (18.18%), 5/22 (22.73%), and 13/16 (81.25%), respectively. Statistically significant differences existed in the two sets of data (P<0.05). Positive rates of Gli-2 in the Masaoka stages Ⅰ, Ⅱ, Ⅲ, and Ⅳ were 2/10 (20%), 12/41 (29.27%), 4/6 (66.67%), and 5/7 (71.43%), respectively. The statistical differences of these two sets of data were also significant (P<0.05). 2) The expression levels of Gli-2 in tumor tissues were closely correlated with the pleura (P<0.05) but not associated with gen-der, age, myasthenia gravis, and necrosis with hemorrhage (P>0.05). 3) The positive labeling indexes of Ki-67 in invasive and non-inva-sive thymomas were 7.14 ± 6.99 and 15.24 ± 9.13, respectively. The differences between both thymomas were statistically significant (P<0.05). 4) A positive correlation existed in the expression of Ki-67 and Gli-2 in thymomas. Five-year progression-free survival (PFS) rate was lower in the Gli-2 positive group (56.5%, 13/23) than in the negative group (92.7%, 38/41). The Ki-67-positive group (61.5%, 16/26) also showed a lower five-year PFS than that in the negative group (92.1%, 35/38), with statistically significant differences be-tween the two groups (P<0.05). Multivariate Cox's proportional hazard regression analysis indicated that the Gli-2-positive group ex-pression, Ki-67-positive group expression, and invasion of the pleura were independent prognostic factors of thymic tumors. Conclu-sion:The expression of Gli-2 and Ki-67 showed a positive correlation with thymic tumors. Detecting the combined expression of Gli-2 and Ki-67 may elucidate the clinicopathological features and prognoses of patients with thymic tumors.
