1Irritable bowel syndrome: A microbiome-gut-brain axis disorder?显示文摘Irritable bowel syndrome(IBS) is an extremely prevalent but poorly understood gastrointestinal disorder. Consequently, there are no clear diagnostic markers to help diagnose the disorder and treatment options are limited to management of the symptoms. The concept of a dysregulated gut-brain axis has been adopted as a suitable model for the disorder. The gut microbiome may play an important role in the onset and exacerbation of symptoms in the disorder and has been extensively studied in this context. Although a causal role cannot yet be inferred from the clinical studies which have attempted to characterise the gut microbiota in IBS, they do confirm alterations in both community stability and diversity. Moreover, it has been reliably demonstrated that manipulation of the microbiota can influence the key symptoms, including abdominal pain and bowel habit, and other prominent features of IBS. A variety of strategies have been taken to study these interactions, including probiotics, antibiotics, faecal transplantations and the use of germ-free animals. There are clear mechanisms through which the microbiota can produce these effects, both humoral and neural. Taken together, these findings firmly establish the microbiota as a critical node in the gut-brain axis and one which is amenable to therapeutic interventions.Paul J Kennedy John F Cryan Timothy G Dinan Gerard Clarke 2014World Journal of Gastroenterology2014,20,39:20
2Techniques and accuracy of thoracolumbar pedicle screw placement显示文摘Pedicle screw instrumentation has been used to stabilize the thoracolumbar spine for several decades. Although pedicle screws were originally placed via a freehand technique, there has been a movement in favor of pedicle screw placement with the aid of imaging. Such assistive techniques include fluoroscopy guidance and stereotactic navigation. Imaging has the benefit of increased visualization of a pedicle's trajectory, but can result in increased morbidity associated with radiation exposure, increased time expenditure, and possible workflow interruption. Many institutions have reported high accuracies with each of these three core techniques. However, due to differing definitions of accuracy and varying radiographic analyses, it is extremely difficult to compare studies side-by-side to determine which techniques are superior. From the literature, it can be concluded that pedicles of vertebrae within the mid-thoracic spine and vertebrae that have altered morphology due to scoliosis or other deformities are the most difficult to cannulate. Thus, spine surgeons would benefit the most from using assistive technologies in these circumstances. All other pedicles in thethoracolumbar spine should theoretically be cannulated with ease via a free-hand technique, given appropriate training and experience. Despite these global recommendations, appropriate techniques must be chosen at the surgeon's discretion. Such determinations should be based on the surgeon's experience and the specific pathology that will be treated.Varun Puvanesarajah Jason A Liauw Sheng-fu Lo Ioan A Lina Timothy F Witham 2014World Journal of Orthopedics2014,5,2:7

4丁醇同分异构体/汽油混合燃料的燃烧和非常规污染物特性的试验研究(英文)显示文摘本文研究了丁醇同分异构体与汽油混合燃料在进气道喷射的火花点火发动机中的燃烧和排放特性。试验在发动机转速为1200 r/min、发动机负荷为3 bar BMEP 和5 bar BMEP 以及不同混合气空燃比条件下(φ=0.83~1.25)进行,使用了70%体积比的纯汽油和30%体积比的丁醇同分异构体混合燃料(N30,S30,I30 和T30)。结果表明,相比于纯汽油,所有的丁醇同分异构体/汽油混合燃料表现出更高的缸内压力,其中N30 有最高的缸内压力峰值和最早的缸内压力峰值相位;T30 表现出较高的brake燃油消耗率(BSFC)和较低的制动热效率(BTE);相比于其他燃料,N30 的UHC 排放较低而I30 的CO排放较高。在非常规排放物特性方面,相比于纯汽油,丁醇同分异构体/汽油混合燃料有较高的乙醛排放;相比于其他混合燃料,N30 的1,3-丁二烯排放较高。使用丁醇同分异构体/汽油混合燃料可以有效地抑制单环芳烃类质(BTEX)的排放。李元绪 宁智 闫峻豪 Timothy H LEE Chia-fon F LEE 2019Journal of Central South University2019,26,8:3
