Objective To investingate the effect of SGK1 expression level on the prognosis of patients with NSCLC,and provide new biological predictors for the prognosis assessment of patients with NSCLS.Methods One hundred and twenty patients with NSCLC received radical resection in Hanzhong 3201 hospital from Jan 2011 to Dec 2013 were selected.There were 75 males and 45 females,age (63.15 ± 16.44) years,age range 45-80 years.According to the results of immunohistochemical staining,the SGK1 cut-off value determined by the integral was determined,and NSCLC patients were divided into SGK1 high expression group (n =70) and SGK1 low expression group(n =50).The relationship between the expression of SGK1 and clinicopathological features (age,sex,smoking history,alcoholism history,BMI,tissue type,tumor diameter,T stage,N stage,TNM stage,differentiation degree) in NSCLC were analyzed,and the overall survival rate in NSCLC were also analyzed.Followup was carried out by telephone or patient admission.The follow-up period was up to June 1,2018.Chest X-ray and ultrasonography were reviewed every 3 to 6 months after operation,and enhanced CT or MRI were performed if the results were abnormal.The measurement data conforming to normal distribution were expressed by t test and showed by (Mean ± SD);the counting data were tested by x2 test;the 5-year overall survival rate was used as the endpoint event for univariate analysis,and the significant variables for univariate analysis were analyzed by COX risk ratio model for multivariate analysis.The cumulative survival curve was drawn by Kaplan-Meier method,and the difference was tested by Log-rank method.Results The expression level of SGK1 in tissues was not related to age,sex,smoking history,alcoholism,BMI,tissue type and tumor diameter (P ＞ 0.05),but it was related to T stage,N stage,TNM stage and differentiation degree (P ＜ 0.05).The univariate and multivariate COX risk ratio model showed that TNM stage and SGK1 expression were independent factors affecting the 5-year overall survival rate of NSCLC patients (P ＜ 0.05).The results of Kaplan-Meier survival curve showed that the 5-year overall survival rate in NSCLC with low expression of SGK1 was significantly higher than that in NSCLC with high expression of SGK1 (P ＜ 0.05).Conclusions The expression of SGK1 in tissues is closely related to the prognosis of patients with NSCLC.The high expression of SGK1 in tissues is not conducive to the prognosis of patients with NSCLC.

Objective To investigate the prognostic value of serum P-cadherin( P-cad)level in patients with non-small cell lung cancer(NSCLC). Methods A total of 80 patients with NSCLC in Hanzhong 3201 Hospital of Shaanxi Province from January 2012 to December 2013 were selected as study subjects. The relationships between serum P-cad level and clinicopathological characteristics were analyzed. The Cox regres-sion analysis was used to analyze the risk factors affecting prognosis of NSCLC patients. The survival curve was drawn by Kaplan-Meier method and the difference test was carried out by log-rank method. Results There were significant differences in lymph node metastasis(χ2 = 14. 31,P < 0. 001),vascular invasion(χ2 = 5. 56, P = 0. 018)among NSCLC patients with different levels of serum P-cad. Multivariate Cox regression analysis showed that lymph node metastasis(HR = 0. 856,95％ CI:0. 702-0. 955,P = 0. 012),TNM stage(ⅢA HR =1. 315,95％ CI:1. 058-1. 991,P = 0. 024;ⅢB HR = 1. 448,95％ CI:1. 124-2. 215,P = 0. 011;Ⅳ HR =1. 569,95％ CI:1. 182-2. 441,P < 0. 001)and high level of serum P-cad(HR = 1. 815,95％ CI:1. 224-3. 562,P < 0. 001)were risk factors for progression-free survival in NSCLC patients,and lymph node metasta-sis(HR = 0. 755,95％ CI:0. 652-0. 915,P = 0. 022),poor differentiation(HR = 1. 622,95％ CI:1. 112-2. 015,P < 0. 001),TNM stage(ⅢA HR = 1. 335,95％ CI:1. 064-2. 014,P = 0. 011;ⅢB HR = 1. 489, 95％ CI:1. 129-2. 297,P < 0. 001;Ⅳ HR = 1. 622,95％ CI:1. 192-2. 501,P < 0. 001)and high level of serum P-cad(HR = 1. 677,95％ CI:1. 193-2. 668,P < 0. 001)were risk factors for overall survival of NSCLC patients. The results of Kaplan-Meier survival curve showed that the overall survival and progression-free survival of patients with high level of serum P-cad were shorter than those of patients with low level of serum P-cad(χ2 = 5. 18,P = 0. 015;χ2 = 5. 48,P = 0. 011). Conclusion High level of serum P-cad is closely related to poor prognosis in NSCLC patients.

Objective: To investigate the expressions of miR-144 and lncRNA DNAJC3-AS1 in breast cancer tissues and their effects on chemo-resistance of breast cancer MCF-7 cells. Methods: A total of 196 pairs of breast cancer tissues and corresponding adjacent normal tissues collected between January, 2012 and December, 2016 in Department of Oncology, 3201 Hospital were used for this study. The relative expressions of DNAJC3-AS1, DNAJC3 and miR-144 in collected tissues were determined using qPCR, and their impact on the survival of BC patients was also analyzed. The targeted binding relationship between DNAJC3-AS1 and miR-144 was verified by Luciferase reporter gene assay. DNAJC3-AS1 over-expression plasmid and miR-144 mimics were transfected into MCF-7 cell lines respectively, and qPCR was used to verify the transfection efficiency. The effects of DNAJC3-AS1 and miR-144 overexpression on proliferation and cisplatin sensitivity of MCF-7 cells were verified by CCK-8 assay. Results: DNAJC3-AS1 and its host gene DNAJC3 were highly expressed in BC tissues (all P<0.01), and these two were positively correlated (r=0.451, P<0.01); in addition, patients with high expressions of DNAJC3-AS1 and DNAJC3 had a shorter survival period (all P<0.01). miR-144 was highly expressed in BC tissues (P<0.01) and negatively correlated with DNAJC3-AS1 (r=-0.524, P<0.01). The average over-expressionfold for DNAJC3-AS1 was 13.47 (P<0.01), while the fold for miR-144 was 20.27 (P<0.01). Bioinformatics analysis and fluorescence reporter gene assay confirmed that DNAJC3-AS1 could specifically bind to miR-144. MCF-7 cell lines over-expressing DNAJC3-AS1 and miR-14 were successfully constructed; compared with control group, cells in DNAJC3-AS1 over-expression group exhibited significantly enhanced proliferation and reduced cisplatin-sensitivity (all P<0.01), while the cells in miR-144 over-expression group showed significantly enhanced drug sensitivity (P<0.01). Conclusion: miR-144 and lncDNAJC3-AS1 were highly expressed in BC tissues, miR-144 promotes cisplatin sensitivity of BC MCF-7 cells through targeting DNAJC3-AS1.
