Objective To study the effects of the expression of hypoxia inducible factor-1 alpha (HIF-1?) induced by FasL on the invasiveness of rectal cancer cells. Methods With molecular cloning method, eukaryotic expression vectors of pcDNA3.1 FasL containing total length of FasL cDNA sequence were transfected into human rectal cancer cells HR-8348. The cell invasiveness was examined. A hypoxia model of HR-8348 was reproduced, and its invasiveness was assessed with transwell methodology. Expression of HIF-1? was assayed by Western bloting. Results The number of HR-8348 cells transfected with FasL penetrated transwell filter membrane was larger (12.930?2.434) than that of empty vector transfected cells (7.670?2.093) and control cells (8.133?1.959) with statistically significant differences (P0.05), but it was significantly higher in FasL positive HR-8348 cells than in FasL negative cells at 12h and 24h after hypoxia (P0.05). Conclusions FasL is an effective factor inducing HIF-1? expression, and FasL expression correlates positively with HIF-1? expression. Enhanced FasL expression in rectal cancer cells could induce higher expression of HIF-1?, enable the tumor cells to adapt to hypoxia environment, and enhance the invasiveness of tumor cells.

Objective To study the significance of monitoring postoperative hematogenous micrometastasis of colorectal cancer. Methods The micrometastatic cancer cells in peripheral blood and bone marrow of the perioperative patients were investigated by CK20 mRNA RT-PCR. Results The positive rates(16.3%) of hematogenous dissemination without relapse or metastasis after operation were significantly lower than that(88.9%) in patients with postoperative relapse or metastasis. There were four types of hematogenous dissemination. (1) Postoperative temporary negatives.(2)Consistant positives. (3) CK-20 turned positive postoperatively. (4) Consistant negatives. All the 6 patients that died had positive CK-20 preoperatively. Conclusions The hematogenous dissemination of colorectal cancer plays an important role in postoperative relapse. The dynamic monitoring of CK-20 predicts hematogenous dissemination of colorectal cancer.

Objective To verify the best treatment strategy in reducing prostate specific antigen (PSA) progression and death rate in patients with locally advanced prostate cancer by a meta-analysis. Methods The literature search strategy was followed according to the Collaborative Review Group search strategy. Published data of randomized clinical trials comparing radical prostatectomy (RP) plus adjuvant therapy to either RP alone or other treatment were analyzed. Both fixed effect model and randomized effect model were applied and odds ratio (OR) with its 95% confidence interval (95% CI) was also used as the effect size 'estimate. Results Eight clinical trials were chosen with total in-volved cases of 3826. There were 5 trials compared post radical prostatectomy plus adjuvant hormonal therapy with radical prostatectomy alone. PSA progression was used as the indicator of progression and the combined OR was 0.86 (95%CI 0.48-1.56). There were 3 trails compared the combination of radical prostateetomy with hormonal therapy and radical prostatectomy alone. Disease specific death rate was used as the evaluating criteria and the OR was 0.72(95%CI,0.51-1.02). Conclusion RP plus adjuvant hormonal therapy can reduce PSA progression of patients with locally advanced pros-tate cancer, but it has no significant effect on disease specific death rate.

Objective To study the clinical features, effects of therapeutic regimen and prognosis of patents with mantle cell lymphoma (MCL). Methods Clinical data of 27 MCL patients admitted in Tianjin Medical University Cancer Institute&Hospital from January 2008 to December 2014 were retrospectively analyzed. Cox regression analysis was used to analyze influencing factors of prognosis of MCL. Results The median age was 68 years old for 27 patients, and the male-to-female ratio was 4.4∶1. Ann Arbor staging showed that 25 cases were stageⅢ-Ⅳ(92.6%), 8 cases were heptosplenomegaly (29.6%), 7 cases showed extranodal involvement (25.9%). ECOG scoring showed that 4 cases with scores of 2-4 (14.8%), 8 cases were 0-3 (29.6%), 14 cases were 4-5 (51.9%) and 5 cases were 6-11 (18.5%). The Ki-67 index≤30%was found in 9 cases (33.3%), and>30%was found in 18 cases (67.7%). Patients with B symptom was found in 10 (37.0%). The elevated lactate dehydrogenase (LDH) was found in 17 cases (63.0%). The increased Beta 2- microglobulin was found in 8 cases (29.6%). Seven patients were found with bone marrow involvement. The total effective rate (ORR) was 81.8%in group with R-CHOP method, and the ORR was 68.8%in group with CHOP method. Multivariate analysis showed that age, LDH and Ki-67 were independent factors influencing the prognosis of MCL (P<0.05). Conclusion Most patients with MCL are found in advanced stage. Patients with age>60 years, elevated LDH and Ki-67 index>30%are with poor prognosis.

Objective To investigate the protective effects of memantine on isofluane ̄induced decrease of proliferation in neural stem cells ( NSCs) and the potential mechanisms in vitro. Methods Neural stem cells were isolated from rat hippocampi (postnatal day 1) and grew in culture. Cultured NSCs were randomly divided into the control ( Group Control), Vehicle (Group Vehicle), Isoflurane ( Group Iso), Isoflurane +Memantine ( Group Iso +Mem) and Isoflurane + Memantine +LY294002 groups (Group Iso+Mem+LY).Proliferation was assessed by cell counting and BrdU incorporation.Western blot was conducted to detect protein expression of phospho ̄Akt. Results Compared with the control group,BrdU incorporation and phospho ̄Akt expressions in neural stem cells significantly declined after 2.4% isoflurane exposure for 6 h (P<0.01).However, isofluane ̄induced decrease of BrdU incorporation and phospho ̄Akt expressions was attenuated by the treatments of memantine (P<0.01)). It was showed that Akt inhibitors LY294002 reversed the protective effects on neural stem cells proliferation by memantine(P<0.01). Conclusion The results suggest that memantine treatment might attenuate isofluane ̄induced decrease of proliferation in neural stem cells via Akt signaling pathway.
