0.05).The mRNA and protein expressions of survivin in cells transfected by 100-200nmol/L siRNA were significantly lower than those of untransfected cells(P0.05).Conclusion Silencing survivin gene by the RNAi technique can decrease effectively the expressions of survivin gene and protein,suppress significantly the growth and proliferation of A549 cells,and induce apoptosis of A549 cells.The inhibitory effect of RNAi is characterized by its specificity,high efficiency and durability.This may lay an experimental foundation for further study of gene therapy in lung cancer.

Objective To assess the effects of survivin-specific siRNA on chemosensitivity of lung cancer cell A549 to paclitaxel in vitro.Methods For determining if survivin-specific siRNA could enhance the responsiveness of lung cancer to paclitaxel,human lung adenocarcinoma cell lines A549(p53 wild-type)were divided into four different treatment groups:control,survivin siRNA,paclitaxel and survivin siRNA+paclitaxel.The effects on cell proliferation,cell cycle and apoptosis were analyzed by MTT assay and flow cytometry,respectively.The protein expression levels of survivin,p21 and PARP were evaluated by Western blot experiments.Results Survivin-specific siRNA showed a augmenting effect on the chemosensitivity of different concentrations of paclitaxel(P

Objective To observe the effects of hot compress on oxaliplatin-induced neurotoxicity.Methods One hundred and twenty patients undergoing chemotherapy with oxaliplatin enrolled in this study were randomly assigned to the control group and expenment group.The control group was given routine health education and the experiment group was treated with hot compress.We compared the incidence of nerotoxocity after 2 and 4 treatment courses.Resulsts The incidence of neurotoxiticity was 75.0%in the experiment group and 91.7%in the control group after 2 treatment courses(P<0.01).The incidences were 86.7%in the experiment group and 98.3%in the control group after 4 treatment courses(P<0.001).Conclusion Hot compress can effectively reduce the incidence of neurotoxicity induced by chemotherapy with oxaliplatin.

Human gut microbiota play an essential role in both healthy and diseased states of humans. In the past decade, the interactions between microorganisms and tumors have attracted much attention in the efforts to understand various features of the complex microbial communities, as well as the possible mechanisms through which the microbiota are involved in cancer prevention, carcinogenesis, and anti-cancer therapy. A large number of studies have indicated that microbial dysbiosis contributes to cancer susceptibility via multiple pathways. Further studies have suggested that the microbiota and their associated metabolites are not only closely related to carcinogenesis by inducing inflammation and immune dysregulation, which lead to genetic instability, but also interfere with the pharmacodynamics of anticancer agents. In this article, we mainly reviewed the influence of gut microbiota on cancers in the gastrointestinal (GI) tract (including esophageal, gastric, colorectal, liver, and pancreatic cancers) and the regulation of microbiota by diet, prebiotics, probiotics, synbiotics, antibiotics, or the Traditional Chinese Medicine. We also proposed some new strategies in the prevention and treatment of GI cancers that could be explored in the future. We hope that this review could provide a comprehensive overview of the studies on the interactions between the gut microbiota and GI cancers, which are likely to yield translational opportunities to reduce cancer morbidity and mortality by improving prevention, diagnosis, and treatment.
