| 1 | Microwave Synthesis of Large Few-Layer Graphene Sheets in Aqueous Solution of Ammonia显示文摘Few-layer graphene (FLG) sheets with sizes exceeding several micrometers have been synthesized by exfoliation of expanded graphite in aqueous solution of ammonia under microwave irradiation, with an overall yield approaching 8 wt.%. Transmission electron microscopy (in bright-field and dark-field modes) together with electron diffraction patterns and atomic force microscopy confirmed that this graphene material consisted mostly of mono-, bi- or few-layer graphene (less than ten layers). The high degree of surface reduction was confirmed by X-ray photoelectron and infrared spectroscopies. In addition, the high stability of the FLG in the liquid medium facilitates the deposition of the graphene material onto several substrates via low-cost solution-phase processing techniques, opening the way to subsequent applications of the material. | Izabela Janowska Kambiz Chizari Ovidiu Ersen Spyridon Zafeiratos Driss Soubane Victor Da Costa Virginie Speisser Christine Boeglin Matthieu Houllé Dominique Bégin Dominique Plee Marc-Jacques Ledoux Cuong Pham-Huu | 2010 | Nano Research2010，3，2： | 22 |
| 2 | 颅底骨折患者预防性使用抗生素预防脑膜炎的系统评价(英文)显示文摘目的 评价颅底骨折患者预防性使用抗生素预防脑膜炎的效果。方法 检索Cochrane临床对照试验资料库(CENTRAL)(Cochrane图书馆2005年第3期)、MEDLINE(1966~2005.09)、EMBASE(1974~2005.06)和LILACS(1982~2005.09)。电子检索美国神经外科医师协会会议记录(1997~2005.09),手工检索神经外科学会欧洲联合会会议记录摘要(1995,1999,2003)。收集比较抗生素与安慰剂或空白对照的随机对照试验。同时对检出的非随机对照试验单独进行Meta分析以比较结果。至少由两名研究者独立评价每项试验的质量并提取数据。采用RevMan4.2软件进行Meta分析。结果 纳入的5个随机对照试验和17个非随机对照试验比较了颅底骨折患者使用不同类型的预防性抗生素与安慰刹或空白对照的效果。但多数试验对方法学细节描述不充分。所有试验均将脑膜炎纳入其主要结局。共评价了符合Meta分析纳入标准的四个随机对照试验,共包括208例受试者。在降低脑膜炎的发生率、全因病死率、脑膜炎病死率和需要手术干预的脑脊液漏的发生率等方面,预防性抗生素组与对照组无显著差异。对伴或不伴脑脊液漏的患者进行亚组分析以评价其主要结局,并对所有检出的非随机对照试验(共包括2168例受试者)进行Meta分析,得出的结果与随机数据一致。 结论 现有的随机对照试验证据并不支持对颅底骨折患者预防性使用抗生素,无论其有无脑脊液漏的迹象。在更多的研究完成之前,尚无法确定颅底骨折患者使用抗生素的效果,因为迄今发表的研究均存在偏倚,尚需更多设计完善的大样本随机对照试验。 | Ratilal B Costa J Sampaio C 陈耀龙(译) 刁骧(审校) | 2006 | 中国循证医学杂志2006，6，8： | 7 |
| 3 | Contrast-induced acute kidney injury in kidney transplant recipients: A systematic review and meta-analysis显示文摘AIM To evaluate the incidence of contrast-induced acute kidney injury(CIAKI) in kidney transplant recipients. METHODS A literature search was performed using MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from the inception of the databases through July 2016. Studies assessing the incidence of CIAKI in kidney transplant recipients were included. We applied a randomeffects model to estimate the incidence of CIAKI.RESULTS Six studies of 431 kidney transplant recipients were included in the analyses to assess the incidence of CIAKI in kidney transplant recipients. The estimated incidence of CIAKI and CIAKI-requiring dialysis were 9.6%(95%CI: 4.5%-16.3%) and 0.4%(95%CI: 0.0%-1.2%), respectively. A sensitivity analysis limited only to the studies that used low-osmolar or iso-osmolar contrast showed the estimated incidence of CIAKI was 8.0%(95%CI: 3.5%-14.2%). The estimated incidences of CIAKI in recipients who received contrast media with cardiac catheterization, other types of angiogram, and CT scan were 16.1%(95%CI: 6.6%-28.4%), 10.1%(95%CI: 4.2%-18.0%), and 6.1%(95%CI: 1.8%-12.4%), respectively. No graft losses were reported within 30 d post-contrast media administration. However, data on the effects of CIAKI on long-term graft function were limited.CONCLUSION The estimated incidence of CIAKI in kidney transplant recipients is 9.6%. The risk stratification should be considered based on allograft function, indication, and type of procedure. | Wisit Cheungpasitporn Charat Thongprayoon Michael A Mao Shennen A Mao Matthew R D'Costa Wonngarm Kittanamongkolchai Kianoush B Kashani | 2017 | World Journal of Transplantation2017，7，1： | 2 |
| 4 | Resveratrol attenuates metabolic,sperm,and testicular changes in adult Wistar rats fed a diet rich in lipids and simple carbohydrates显示文摘High-fat diets affect male reproduction and sexual function.Therefore,we evaluated the effects of prolonged resveratrol administration on the metabolic,sperm,and testicular parameters of rats fed a cafeteria diet.Male Wistar rats were divided at weaning into control(Cv n=20)and cafeteria(CAF,n=16)groups.At 3 months,half of them were given daily supplementations of resveratrol(C-R,n=10;CAF-R,n=8)at a dosage of 30 mg kg-1 body mass for 2 months.Animals were killed at 5 months of age,and blood,spermatozoa,and testes were collected for further analysis.Data were analyzed by one-way ANOVA,and P<0.05 was considered statistically significant.The CAF diet promoted hyperglycemia(P<0.0001),and treatment with resveratrol reversed this condition(P<0.0001).The CAF diet reduced sperm viability and motility,while resveratrol improved these parameters(F<0.05).Regarding testicular morphology,the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group(P=0.0007).Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group.However,the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group(P=0.0024).Although it did not modify body mass,the consumption of a CAF diet promoted hyperglycemia,adverse testicular morphology remodeling,and abnormal sperm,which were attenuated by treatment with resveratrol,thus suggesting a protective effect of this antioxidant on spermatogenesis. | Fabiana A de Oliveira Waldemar S Costa Francisco J B Sampaio Bianca M Gregorio | 2019 | Asian Journal of Andrology2019，21，2： | 2 |
