| 1 | 干砂最大剪切模量的共振柱与弯曲元试验显示文摘对德国4种干砂试样进行了共振柱与弯曲元对比试验,旨在分析弯曲元法测定砂土最大剪切模量时存在问题和解决方法。研究表明:时域初达法判定的剪切波传播时间较其他方法具有更好的稳定性;弯曲元试验测定最大剪切模量输入电压脉冲频率的减小而减小,衰减程度因砂土类型而异,该影响随围压的增大而减弱;对比分析表明,弯曲元与共振柱试验测定的最大剪切模量具有良好的线性关系,对柏林砂和不伦瑞克砂,存在一个临界最大剪切模量,小于该临界值时,弯曲元测值大于共振柱测值,而大于该临界值时,前者小于后者,两者差值随土样刚度增大而增大。对比研究指出,弯曲元试验尽可能采用合适高频脉冲电压作为激发电压,实践中应事先与共振柱试验进行对比。 | 柏立懂 项伟 SAVIDIS A Stavros RACKWITZ Frank | 2012 | 岩土工程学报2012，34，1： | 19 |
| 2 | Meta-analysis of laparoscopic vs open cholecystectomy in elderly patients显示文摘AIM:To investigate the comparative effect of laparoscopic and open cholecystectomy in elderly patients.METHODS:Laparoscopic cholecystectomy has induced a revolution in the treatment of gallbladder disease.Nevertheless,surgeons have been reluctant to implement the concepts of minimally invasive surgery in older patients.A systematic review of Medline was embarked on,up to June 2013.Studies which provided outcome data on patients aged 65 years or older,subjected to laparoscopic or open cholecystectomy were considered.Mortality,morbidity,cardiac and pulmonary complications were the outcome measures of treatment effect.The methodological quality of selected studies was appraised using valid assessment tools.Τhe random-effects model was applied to synthesize outcome data.RESULTS:Out of a total of 337 records,thirteen articles(2 randomized and 11 observational studies)reporting on the outcome of 101559 patients(48195in the laparoscopic and 53364 in the open treatment group,respectively)were identified.Odds ratios(OR)were constantly in favor of laparoscopic surgery,in terms of mortality(1.0%vs 4.4%,OR=0.24,95%CI:0.17-0.35,P<0.00001),morbidity(11.5%vs 21.3%,OR=0.44,95%CI:0.33-0.59,P<0.00001),cardiac(0.6%vs 1.2%,OR=0.55,95%CI:0.38-0.80,P=0.002)and respiratory complications(2.8%vs 5.0%,OR=0.55,95%CI:0.51-0.60,P<0.00001).Critical analysis of solid study data,demonstrated a trend towards improved outcomes for the laparoscopic concept,when adjusted for age and co-morbid diseases.CONCLUSION:Further high-quality evidence is necessary to draw definite conclusions,although bestavailable evidence supports the selective use of laparoscopy in this patient population. | Stavros A Antoniou George A Antoniou Oliver O Koch Rudolph Pointner Frank A Granderath | 2014 | World Journal of Gastroenterology2014，20，46： | 17 |
| 3 | Implant retention after acute and hematogenous periprosthetic hip and knee infections: Whom, when and how?显示文摘Periprosthetic joint infections(PJI) of the hip and the knee are grossly classified as early post-operative, acute hematogenous and late chronic infections. Whereas two-stage exchange arthroplasty is the standard of care in North America for treating chronic infections, irrigation and debridement(I and D) with retention of implants has been used in an attempt to treat the other two types of PJIs. The rationale of this approach is that a PJI may be eradicated without the need of explanting the prostheses, as long as it has not transitioned into a chronic state. With the present paper, we review current evidence regarding the role of I and D with implant retention for treating PJIs of the hip and the knee. While a very wide range of success rates is reported in different studies, a short period of time between initiation of symptoms and intervention seems to play a prominent role with regards to a successful outcome. Moreover, pathogens of higher virulence and resistance to antibiotics are associated with a poorer result. Specific comorbidities have been also correlated with a less favorable outcome. Finally, one should proceed with serial I and Ds only under the condition that a predefined,aggressive protocol is applied. In conclusion,when treating a PJI of the hip or the knee, all the above factors should be considered in order to decide whether the patient is likely to benefit from this approach. | Georgios K Triantafyllopoulos Vasileios Soranoglou Stavros G Memtsoudis Lazaros A Poultsides | 2016 | World Journal of Orthopedics2016，7，9： | 7 |
| 4 | The omega-3 and retinopathy of prematurity relationship显示文摘The aim of this article is to examine the effect of omega-3(ω-3) long-chain polyunsaturated fatty acids(LCPUFAs) intake on retinopathy of prematurity(ROP) by reviewing the experimental and clinical trials conducted on animal models and infants.LCPUFAs demonstrate cytoprotective and cytotherapeutic actions contributing to a number of anti-angiogenic and neuroprotective mechanisms within the retina.Their intake appears to have a beneficial effect on ischemia,oxidative stress,inflammation and cellular signaling mechanisms,influencing retinal cell gene expression and cellular differentiation.ω-3 LCPUFAs may modulate metabolic processes that activate molecules implicated in the pathogenesis of vasoproliferative and neurodegenerative retinal diseases such as ROP. | Angelakis Malamas Angeliki Chranioti Christos Tsakalidis Stavros A Dimitrakos Asimina Mataftsi | 2017 | International Journal of Ophthalmology(English edition)2017，10，2： | 4 |
| 5 | 振动历史对砂土非线性剪切模量和阻尼比的影响显示文摘利用Stokoe共振柱的非共振模式对干砂试样施加先期扭剪振动,系统研究振动历史对砂土非线性动力特性的影响。研究发现:对某一砂样,存在一个阀值循环次数,小于该阀值前,砂土最大剪切模量随循环次数衰减,大于该阀值后,随之增大。砂土归一化剪切模量几乎不受预荷载频率影响,阻尼比随预荷载频率增大而增大。归一化剪切模量随循环次数增大而减小,阻尼比则随之增大。增大围压将减弱先期振动对归一化模量和阻尼比的影响,而降低围压将进一步放大先期振动的影响。振动历史对归一化剪切模量和阻尼比的影响是土颗粒之间磨损作用和颗粒竖向再定向作用的共同结果。 | 柏立懂 项伟 Savidis A Stavros Rackwitz Frank | 2012 | 岩土工程学报2012，34，2： | 3 |
