Objective To discuss the effect of 5-Aza-CdR on pancreatic carcinoma Capan-2 cell proliferation and PCDH8 gene expression.Methods Pancreatic carcinoma Capan-2 cells were treated with different doses of 5-Aza-CdR with or without gemcitabine,negative control group without drug,0.08μmol/L group with 0.08μmol/L 5-Aza-CdR,0.40 μmol/L group with 0.40 μmol/L 5-Aza-CdR,2.00 μmol/L group with 2.00 μmol/L 5-Aza-CdR,10 μmol/L group with 10 μmol/L 5-Aza-CdR,50 μmol/L group with 50 μmol/L 5-Aza-CdR. The inhibition ratio of Capan-2 cell proliferation were observed by MTT assay and PCDH8 gene and protein expression were detected by RT-PCR and Western blot. Results The inhibition ratio was increased with 5-Aza-CdR dose increasing(P<0.01),but decreased apparently with times extending(P<0.01). Inhibition ratio in 5-Aza-CdR and gemcitabine group was higher than those with only 5-Aza-CdR or gemcitabine groups(P<0.05 or P<0.01).The levels of PCDH8 gene and protein expression were increased significantly in 5-Aza-CdR treatment groups,with dose dependent (P <0.01 ).Conclusion 5-Aza-CdR can inhibit the proliferation of pancreatic carcinoma Capan-2 cell proliferation,and increase PCDH8 gene expression. The inhibition effect is strong when combined with gemcitabine.

Objective To assess the effect of PRISMA statement on intervention-related systematic reviews and meta-analyses published in Evidence-based medicine .Methods Intervention-related systematic reviews and meta-analyses published in Evidence-based medicine from 2001 to 2011 were assessed according to the PRISMA scale and analyzed by Meta Analysist software.Results Seventy intervention-related systematic reviews and meta-analyses involving 14-disease spectra were included in this study.PRISMA statement and systematic reviews and meta-analysespublished by au-thors in colleges and universities could improve their academic level (P<0.05), fund support and the number of authors showed no significant effect on their academic level.Conclusion Literature retrieval methods,literature screening methods,bias assessment methods, and other analyzing methods used systematic reviews and meta-analyses published in Evidence-based medicine and their academic level can be improved by PRISMA statement.

Objective To elucidate the clinical characteristics and coronary angiographic findings of patients underwent PCI before and after drug-eluting stents(DES).Methods DESIRE(Drug-Eluting Stent Impact on revascularization) was a retrospective registry of patients who received revascularization therapy during July,2001 through June,2002(non-DES era) and July,2003 through February,2004(DES era).In this analysis,we used the DISIRE data to examine the clinical and angiographic features of patients who received PCI in the different era.Results Among 3763 patients in the registry,2180 patients were analyzed(763 were in the non-DES era and 1417 were in the DES era).In the DES era,more diseased vessels(1.31?0.54 vs 1.39?0.61,P

Objective To investigate the relationship between histological chorioamnionitis(HCA) and the outcome of preterm labor. Methods A total of 218 cases of premature delivery in the Department of Obstetrics and Gynecology of our hospital from January, 2015 to December, 2017 were divided into two groups according to the result of placenta pathological diagnosis. The observation group was diagnosed with histological chorioamnionitis by placenta pathology examination. The control group was not diagnosed with histological chorioamnionitis. The delivery gestational week, the rate of premature rupture of membranes, the rate of puerperal infection, the rate of postpartum hemorrhage, the rate of wound healing failure, the average body mass of newborn infants, the rate of early-onset sepsis, asphyxia, respiratory distress syndrome rate, pathological jaundice rate, neonatal mortality between the two groups were compared. And the impact of histological chorioamnionitis on the outcome of preterm labor was explored. Results The delivery gestational week of the observation group was (32. 0±1. 0) weeks, and the rate of postpartum hemorrhage, the rate of premature rupture of membranes, the rate of puerperal infection and the rate of wound healing were 21. 24％, 80. 50％, 16. 81％, 11. 50％, respectively. The delivery gestational week of the control group was(34. 0±1. 0) weeks, and the rate of postpartum hemorrhage, the rate of premature rupture of membranes, the rate of puerperal infection and the rate of wound healing were 10. 48％, 65. 70％, 7. 62％, 3. 81％, respectively. The delivery gestational week of the observation group was small. And the rate of premature rupture of membranes, wound healing failure rate, puerperal infection rate, postpartum hemorrhage rate in the observation group was significantly higher than that of the control group, and the difference was statistically significant(P＜0. 05). The mean neonatal weight in the observation group was(1710±355)g,and the asphyxia rate, early-onset sepsis rate, respiratory distress syndrome rate, pathological jaundice rate and neonatal mortality were 21. 24％, 33. 63％, 38. 05％, 19. 47％ and 9. 73％. The mean neonatal weight in the control group was(2270±450)g,and the asphyxia rate, early-onset sepsis rate, respiratory distress syndrome rate, pathological jaundice rate, neonatal mortality were 9. 52％, 18. 10％, 12. 38％, 8. 57％, 2. 86％. The average body weight of infants in the observation group was low. And the rates of early onset sepsis, asphyxia, respiratory distress syndrome, pathological jaundice and neonatal mortality were significantly increased. The difference was significant (P＜0. 05). Conclusion The placental pathology examination in all preterm patients should be done to avoid missed diagnosis of HCA, and to help early diagnosis and treatment of pregnant women with intrauterine infection and high-risk newborns and improve prognosis.

Sodium alginate (SA) is a kind of natural polymer material extracted from kelp, which has excellent biocompatibility, non-toxicity, biodegradability and abundant storage capacity. The formation condition of sodium alginate gel is mild, effectively avoiding the inactivation of active substances. After a variety of preparation methods, sodium alginate microspheres are widely used in the fields of biomaterials and tissue engineering. This paper reviewed the common methods of preparing alginate microspheres, including extrusion, emulsification, electrostatic spraying, spray drying and coaxial airflow, and discussed their applications in biomedical fields such as bone repair, hemostasis and drug delivery.

As a novel and promising antitumor target, AXL plays an important role in tumor growth, metastasis, immunosuppression and drug resistance of various malignancies, which has attracted extensive research interest in recent years. In this study, by employing the structure-based drug design and bioisosterism strategies, we designed and synthesized in total 54 novel AXL inhibitors featuring a fused-pyrazolone carboxamide scaffold, of which up to 20 compounds exhibited excellent AXL kinase and BaF3/TEL-AXL cell viability inhibitions. Notably, compound 59 showed a desirable AXL kinase inhibitory activity (IC₅₀: 3.5 nmol/L) as well as good kinase selectivity, and it effectively blocked the cellular AXL signaling. In turn, compound 59 could potently inhibit BaF3/TEL-AXL cell viability (IC₅₀: 1.5 nmol/L) and significantly suppress GAS6/AXL-mediated cancer cell invasion, migration and wound healing at the nanomolar level. More importantly, compound 59 oral administration showed good pharmacokinetic profile and in vivo antitumor efficiency, in which we observed significant AXL phosphorylation suppression, and its antitumor efficacy at 20 mg/kg (qd) was comparable to that of BGB324 at 50 mg/kg (bid), the most advanced AXL inhibitor. Taken together, this work provided a valuable lead compound as a potential AXL inhibitor for the further antitumor drug development.
