OBJECTIVETo investigate the synergistic antitumor effects of combined use of p14ARF gene and 5-fluorouracil (5-Fu) in pancreatic cancer.

METHODSA human pancreatic cancer cell line PC-3 was transfected with lipofectin-mediated recombinant p14ARF gene, and was then administered with 5-Fu. Cell growth, morphological changes, cell cycle, apoptosis, and molecular changes were measured using the MTT assay, flow cytometry, RT-PCR, Western blotting, and immunocytochemical assays.

RESULTSAfter transfection of p14ARF, cell growth was obviously inhibited, resulting in an accumulation of cells in the G(1) phase. The proportion of cells in the G(1) phase was significantly increased from 58.51% to 75.92%, and in the S and G(2)/M phases decreased significantly from 20.05% to 12.60%, and from 21.44% to 11.48%, respectively, as compared with those of the control groups. PC-3/p14ARF cells that underwent 5-Fu treatment had significantly greater G(2)/M phase accumulation, from 11.48% to 53.47%. The apoptopic index was increased in PC-3/p14ARF cells from 3.64% to 19.62%. The MTT assay showed p14ARF-expressing cells were significantly more sensitive to 5-Fu (0.01 - 10 mg/L) than those devoid of p14ARF expression (P < 0.01). Western blotting showed p14ARF upregulates p53 expression.

CONCLUSIONCombined use of p14ARF gene and 5-Fu acts synergistically to inhibit pancreatic cancer cell proliferation, suggesting a new anticancer strategy.

BACKGROUND: A number of clinical trials addressing olfactory ensheathing cells for the treatment of chronic spinal cord injury have been conducted in the world, but the efficacy and safety are still controversial. OBJECTIVE: To evaluate the safety and efficacy of olfactory ensheathing cell transplantation for chronic spinal cord injury, and to further compare its short-and long-term efficacy. METHODS: PubMed, Cochrane Library, EMBASE, CNKI and WanFang databases were searched at July 23, 2018 for retrieval of clinical trials addressing olfactory ensheathing cells in the treatment of chronic spinal cord injury. Types and cases of adverse events during the safety trial should be recorded in detail. In the enrolled studies, American Spinal Injury Association scale was used to assess the motor, light touch, and pinprick scores of spinal cord injury patients before and after cell transplantation. The follow-up time was recorded. Systematic evaluation of efficacy data was performed using Review Manager 5.3. RESULTS AND CONCLUSION: Both short-and long-term follow-up data showed that the neurological function of patients was significantly improved after olfactory ensheathing cell transplantation (P < 0.05) , and the results were homogeneous (I2 < 50％ and P> 0.1). However, the long-term efficacy was not as good as the short-term efficacy, which may be related to chronic rejection and olfactory ensheathing cell survival. The overall adverse event rate was 8.99％, and no complications associated with olfactory ensheathing cells occurred. These findings show that olfactory ensheathing cell transplantation is effective and safe in the treatment of chronic spinal cord injury, but it is still necessary to explore more minimally invasive approaches to reduce surgical complications. In addition, a large number of high-quality experiments and clinical trials are warranted to confirm factors affecting the long-term efficacy of olfactory ensheathing cell transplantation.
