Objective To investigate the expression of p-MNK1 in non-small cell lung cancer and its relationship with clinic pathological features and prognosis.Methods The level of p-MNK1 in 115 cases of nonsmall cell lung cancer was detected by tissue microarray technique and immunohistochemistry technique.Results The level of p-MNK 1 in non-small cell lung cancer was correlated with cancer tissue type (P ＜ 0.05),clinical stage (P ＜ 0.05),lymph node metastasis (P ＜ 0.01) and prognosis (P ＜ 0.05).Cox multiple regression analysis showed that p-MNK1 expression was an independent prognostic factor for non-small cell lung cancer (P ＜ 0.01).Conclusion The level of p-MNK1 in non-small cell lung cancer is associated with poor prognosis.It can be used as an independent prognostic marker and a new therapeutic target.

Objective To investigate the potential application of targeting at vascular endothelial growh factor (VEGF) induced apoptosis in leukemic cell lines by combined use of Bevacizumab and chemotherapeutic drug. Methods Leukemic cells were treated with several drugs at different concentrations in culture. The effect of VEGF, Bevacizumab and co-treated with Ara-C on leukemic cells proliferation were evaluated by CCK-8 and apoptosis and cell cycle were detected by flow cytometry (FCM). Results VEGF could enhance the proliferation of leukemic cells and caused a dose-dependent manner on U937 cell. It also increased the percentage of cells in S phase, tested by, and Bevacizumab group was decreased. Apoptotic rate of cells treated with Bevacizumab or co-treated with Bevacizumab and Ara-C for 48 h were significantly higher when compared with control or Ara-C group, respectively (P<0.05), but the apoptotic rate of VEGF group or VEGF and Ara-C group was lower (P>0.05). There was no significant difference in apoptotic rate between control and combined use of VEGF, Bevacizumab and Ara-C group(P>0.05). Conclusion VEGF could enhance the proliferation of some leukemic cells, and may contribute to leukemic cells survival and a resultant resistance to chemotherapy-triggered cell death. The study also showed that leukemic cells growth was significantly inhibited by Bevacizumab through directly against VEGF, and the sensitivity of leukemic cells for chemotherapeutic drug was increased.

Objective To analyze the clinical features, treatment outcomes and prognosis of patients with urinary tract lymphoma. Methods The clinical data of 16 patients in Tongji Hospital of Tongji University from January 2009 to April 2016 were collected and retrospectively analyzed. Results The median age of these patients was 68 years. The onset symptoms of 14 cases were related to urinary system and imaging studies of 10 cases showed masses in the urinary system. The onset regions of lymphoma included:4 cases were renal lymphoma, 5 cases were adrenal lymphoma, 5 cases were testicular lymphoma, 1 case was prostate lymphoma and 1 case was from urethral mouth. The histological type of 12 cases was diffuse large B-cell lymphoma and 10 patients were non-germinal center B cell-like (non-GCB) molecular profiling. Twelve cases belonged to Ann Arbor stages ⅢE- ⅣE, 10 cases had international prognostic index scores ≥3, and 7 cases had B symptoms. 10 patients were confirmed by surgery. Fourteen cases accepted rituximab-containing regimen chemotherapy. Five cases achieved complete response and 3 were partial response. Conclusions The clinical manifestations and imagine examination of patients with urinary tract lymphoma are lack of specificity. The clinical features are highly aggressive and most of the patients are diagnosed at advanced stage. The main histological type is diffuse large B-cell lymphoma and non-GCB molecular profiling. Treatment regimens include surgery combined with chemotherapy and radiotherapy. Earlier diagnosis and treatment may improve the survival of patients.

ABSTRACT:Objective To investigate the nursing countermeasures of first pregnancy in pa-tients with missed abortion.Methods 54 first pregnancy patients with missed abortion were ran-domly divided into two groups with 27 cases in each.Group A was traditional nursing group,in which patients after admission accepted conventional education and assessment,routine psychologi-cal nursing and routine nursing operation;Based on the routine nursing,B group was special care group with enhancing psychological nursing,nursing before and after miscarriage,individualized nursing and follow-up nursing.The compliance rate within one year,success rate of full-term pregnancy,full-term pregnancy and depression rate were compared.Results The difference in the compliance rate,one year pregnancy rate,the success rate of full-term pregnancy,depression rate was statistically significant.Conclusion The first pregnancy of patients with missed abortion should pay attention to psychological nursing,individualized nursing,education and follow-up nursing,which will be favorable for the outcomes.

Objective To investigate the role of LncRNA ROR in Ad36-induced browning of human adipose-derived stem cells(hADSC). Methods After hADSC was induced by cocktail and Ad36 for 2,4,6,and 8 days,Oil red O staining was performed for observing the adipogenic status. The mRNA expressions of LncRNA ROR, uncoupling protein 1(UCP1),and PRDM16 were detected by real-time PCR and the protein expressions of UCP1 and PRDM16 were detected by Western-blot. After LncRNA ROR was knocked down by siRNA, UCP1 and PRDM16 mRNA and protein expression levels in the process of Ad36-induced adipocyte differentiation were detected by real-time PCR and Western-blot. Results Oil red O staining showed that fat droplets in the cocktail-induced group were larger than those in the Ad36-induced group. Compared with the cocktail group,the mRNA expressions of LncRNA ROR, UCP1 and PRDM16, and the protein expressions of UCP1 and PRDM16 in Ad36 group were significantly increased(P<0.05). The mRNA and protein expressions of UCP1 and PRDM16 in LncRNA ROR knockdown group were significantly lower than those in control group(P<0.05). Conclusion In the process of Ad36-induced hADSC differentiation,the up-regulation of LncRNA ROR may stimulate UCP1 and PRDM16 expression,and thus promote the browning of hADSC.

Objective To investigate the expressions of RNA-binding protein human antigen R(HuR), fatty acid binding protein type 4(FABP4),fatty acid synthetase(FASN),and lipoprotein lipase(LPL)during the differentiation of human adipocytes, and to explore their possible roles. Methods Human adipose-derived mesenchymal stem cells were induced by adipogenic differentiation,and the adipogenesis of cells was observed by oil red O staining. The expressions of HuR,FABP4,FASN,and LPL mRNA and protein were detected by real-time PCR and Western blotting. After HuR was silenced by siRNA, the change of adipogenesis for human adipose-derived mesenchymal stem cells was observed and the expressions of adipogenic genes were detected. Results The expressions of HuR,FABP4,FASN,and LPL mRNA and protein were significantly increased after human adipose-derived mesenchymal stem cells were induced to differentiate into adipocytes(all P<0.01). After HuR expression was down-regulated by siRNA,the adipogenic level of human adipose-derived mesenchymal stem cells was reduced,with decreased protein levels of FABP4,FASN,and LPL(all P<0.05),which were without changes for their mRNA levels. Conclusion HuR promotes the differentiation of human adipocytes mainly via regulating the changes of FABP4,FASN,and LPL protein levels.

OBJECTIVETo investigate the efficacy and side effects of the consecutive chemotherapeutic protocol, Tongji-96, for adult patients with Philadelphia chromosome negative acute lymphoblastic leukemia (Ph-aALL).

METHODSA retrospective analysis was conducted on 95 cases of Ph-aALL patients treated between January 2004 and December 2012 with Tongji-96 regimen in Tongji hospital, Shanghai.

RESULTSAmong these 95 patients, the overall complete remission (CR) rate was 92.6%, 7-year overall survival (OS) and event-free survival (EFS) rates were (39.3±5.9)% and (31.5±5.3)%, respectively, with the median survival of 28 months. Based on multivariable COX proportional hazards regression model analysis, patients with the poor karyotype and failed to achieve CR after first course induction therapy had a higher risk of mortality compared to those who had good or normal cytogenetics and achieved CR after 1 course of induction treatment [the risk ratios (RR) were 3.380 (95% CI 1.530-7.463, P=0.003) and 3.005 (95% CI 1.522-5.933, P=0.002)，respectively]. By means of Kaplan-Meier analysis and Log-rank test，patients aged less than 60 years and successively achieved CR after first induction therapy had more favorable 7-year OS and EFS rates. Patients with normal karyotype and hyperdiploidy had significantly higher 2-year OS and EFS rates compared with those with complex karyotype, t(4;11) translocation and other karyotypes.

CONCLUSIONAge (60 years as the cut-off)，treatment courses for achieving CR and cytogenetics were predictive factors for the prognosis of Ph-aALL from this retrospective study. As a comprehensive and sequential therapy protocol, Tongji-96 regimen was proved to obtain long-term survival, reduce risks for relapse and improve outcomes for part Ph-aALL patients.
