| 1 | 加拿大新生儿重症监护室院内感染及其变化趋势对胎龄<33周早产儿预后的影响(英文)显示文摘败血症是新生儿重症监护室(NICU)的危重病症及造成新生儿死亡的重要原因之一,根据其发病时间,可分为早发(生后2 d内)和晚发(生后2 d后)。其中晚发的新生儿败血症,一般考虑为院内感染(NI)。胎龄越小,出生体重越低,NI的发生率越高。NI的发生率在加拿大各NICU之间差别较大,与各中心医护人员的相关诊疗行为密切相关。在国家卫生研究院"基于循证医学的医疗质量改进项目"的推动下,2003~2009年间加拿大全国NICU总的NI率明显下降,但不同中心各自感染率的变化趋势仍极为不同。本研究纳入了加拿大全国共24家NICU在2008~2012年间所有收入院的胎龄〈33周的早产儿共18 961名,探讨NI率的变化趋势以及其与早产儿预后的关系。 | Caitlin Jantzen Abhay Lodha Mirea Lucia Shoo K Lee Xiang Y Ye Koravangattu Sankaran 姚跃 | 2015 | 中国当代儿科杂志2015，17，10： | 13 |
| 2 | Autophagy inhibition by chloroquine sensitizes HT-29 colorectal cancer cells to concurrent chemoradiation显示文摘AIM:To investigate whether the inhibition of autophagy by chloroquine(CQ)sensitizes rectal tumors to radiation therapy(RT)or concurrent chemoradiation(chemoRT).METHODS:In vitro,HCT-116 and HT-29 colorectal cancer(CRC)cell lines were treated as following:(1)PBS;(2)CQ;(3)5-fluorouracil(5-FU);(4)RT;(5)CQ and RT;(6)5-FU and RT;(7)CQ and 5-FU;and(8)5-FU and CQ and RT.Each group was then exposed to various doses of radiation(0-8 Gy)depending on the experiment.Cell viability and proliferative capacity were measured by3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)and clonogenic assays.Clonogenic survivalcurves were constructed and compared across treatment groups.Autophagy status was determined by assessing the LC3-Ⅱto LC3-Ⅰratio on western blot analysis,autophagosome formation on electron microscopy and identification of a perinuclear punctate pattern with GFPlabeled LC3 on fluorescence microscopy.Cell cycle arrest and cell death were evaluated by FACS and AnnexinⅤanalysis.All experiments were performed in triplicate and statistical analysis was performed by the student’s t test to compare means between treatment groups.RESULTS:RT(2-8 Gy)induced autophagy in HCT-116and HT-29 CRC cell lines at 4 and 6 h post-radiation,respectively,as measured by increasing LC3-Ⅱto LC3-Ⅰratio on western blot.Additionally,electron microscopy demonstrated autophagy induction in HT-29 cells24 h following irradiation at a dose of 8 Gy.Drug treatment with 5-FU(25μmol/L)induced autophagy and the combination of 5-FU and RT demonstrated synergism in autophagy induction.CQ(10μmol/L)alone and in combination with RT effectively inhibited autophagy and sensitized both HCT-116 and HT-29 cells to treatment with radiation(8 Gy;P<0.001 and 0.00001,respectively).Significant decrease in clonogenic survival was seen only in the HT-29 cell line,when CQ was combined with RT at doses of 2 and 8 Gy(P<0.5 and P=0.05,respectively).There were no differences in cell cycle progression or Annexin V staining upon CQ addition to RT.CONCLUSION:Autophagy inhibition by CQ increases CRC cell sensitivity to concurrent treatment with 5-FU and RT in vitro,suggesting that addition of CQ to chemoRT improves CRC treatment response. | Caitlin A Schonewolf Monal Mehta Devora Schiff Hao Wu Bruce G Haffty Vassiliki Karantza Salma K Jabbour | 2014 | World Journal of Gastrointestinal Oncology2014，6，3： | 12 |
| 3 | The impact of ipsilateral testicular atrophy on semen quality and sperm DNA fragmentation response to varicocele repair显示文摘Varicoceles adversely impact semen quality and sperm DNA fragmentation,which typically improve with surgical repair.Some men with varicoceles have ipsilateral testicular atrophy due to damage from the varicocele.This study assessed semen quality and the sperm DNA fragmentation index(DFI)response to varicocele repair in men with ipsilateral testicular atrophy(TA)versus men with no testicular atrophy(NTA).Semen parameter values and DFI in both groups were compared preoperatively and postoperatively.The Mann-Whitney U test and the Wilcoxon signed-rank test were used where appropriate.There were 20 men in the TA group and 121 men in the NTA group with no difference in age,varicocele grade,or preoperative semen parameter values between the two groups.The NTA group had a higher preoperative DFI than the TA group.Both groups showed improvement in semen quality postoperatively,only the TA group showed a significant improvement in DFI,whereas the NTA group showed significant improvements in several parameter values and DFI.The change from preoperative to postoperative parameter values when comparing the two groups revealed a difference in total sperm motile count and DFI,with a larger mean improvement in the NTA group than in the TA group.Both TA and NTA groups showed improved semen quality and DFI after varicocele repair,but the NTA group had more improvement than the TA group.However,only total motile count(TMC)and DFI had a significantly greater mean change in preoperative to postoperative response in the NTA group than in the TA group. | Parviz K Kavoussi Natasha Abdullah Melissa S Gilkey Caitlin Hunn G Luke Machen Shu-Hung Chen Keikhosrow M Kavoussi Amy Esqueda J David Wininger Shahryar K Kavoussi | 2021 | Asian Journal of Andrology2021，23，2： | 2 |
