Double scalar elastic damage constitutive model considering shear damage
Zhang,Jiyang; Liu,Panpan; Shen,BoAbstract The concrete open-web sandwich slab is composed of the vierendeel girders intersecting each other. The vierendeel girder are composed of the upper rib, lower rib and shear key. The upper and lower rib mainly bear the axial force, and the shear keys mainly bear the shear force. A double scalar elastic damage constitutive model considering shear damage was derived to accurately simulate the mechanical pr...
Potentially Modifiable Predictors for Renal Replacement Therapy in Patients wit...
Jiang,Wuhua; Shen,Bo; Wang,Yimei; Xu,Jiarui; Luo,Zhe; Ding,Xiaoqiang; Teng,JieAbstract Objective: To discover potentially modifiable perioperative predictors for renal replacement therapy (RRT) in patients with cardiac surgery-associated acute kidney injury (CSA-AKI). Methods: A cohort of 1773 consecutive cardiac surgery patients with postoperative acute kidney injury (AKI) from January 2013 to December 2015 were included retrospectively. AKI was defined according to the Kidney Disease: ...
Validation of Four Prediction Scores for Cardiac Surgery-Associated Acute Kidne...
Jiang,Wuhua; Xu,Jiarui; Shen,Bo; Wang,Chunsheng; Teng,Jie; Ding,XiaoqiangAbstract Objective: To assess the clinical value of four models for the prediction of cardiac surgery-associated acute kidney injury (CSA-AKI) and severe AKI which renal replacement therapy was needed (RRT-AKI) in Chinese patients. Methods: 1587 patients who underwent cardiac surgery in the department of cardiac surgery in the Zhongshan Hospital, Fudan University, between January 2013 and December 2013 were enr...
Association between vitamin D deficiency and anemia in inflammatory bowel disease...
Fialho,Andre; Fialho,Andrea; Kochhar,Gursimran; Shen,BoABSTRACTBackground:Vitamin D deficiency is commonly seen in patients with inflammatory bowel disease (IBD). Vitamin D deficiency in IBD patients with ileostomy has not been systemically studied. The aim of the study was to assess the frequency and risk factors associated with low 25(OH) D3 levels in those patients.Methods:112 eligible IBD patients with ileostomy were studied. Demographic, clinical, and endoscopic ...
Needle knife-assisted polypectomy in hot snare-resistant fibrotic inflammatory ...
Wu,Xian-rui; Liu,Xiu-li; Shen,BoBACKGROUND: Inflammatory polyps are common sequelae in patients with inflammatory bowel diseases (IBD). Those polyps can usually be removed with snare polypectomy. There were limited data evaluating the management of hot snare-resistant inflammatory polyps.METHODS: We reported on two cases with hot snare-resistant inflammatory polyps, one was a Crohn's disease (CD) patient with the polyp at the ileo-colonic ana...
Closure of leak at the tip of the "J" after ileal pouch-anal anastomosis using ...
Lian,Lei; Shen,BoOBJECTIVE: leaks from the body or the tip of the J-pouch can occur after restorative proctocolecotmy. Although it may follow an indolent clinical course, it often requires surgical repair or pouch revision. Here we describe a novel endoscopic approach to close the leak at the tip of the J pouch. DESIGN: pouchoscopy was performed under sedation and endoscopic over-the-scope clipping system was used for the manag...
Successful endoscopic treatment of fecalith blocking sinus in a patient with il...
Ma,Jessica; Zhang,Brook; Wu,Xian-rui; Shen,BoBackground: Ulcerative colitis patients who underwent restorative proctocolectomy with ileal pouch-anal anastomosis can develop various mechanical complications. Among them is presacral sinus resulting from chronic anastomotic leak. Methods: We present a symptomatic patient with a large fecalith blocking the sinus which was successfully treated with Doppler ultrasound guided endoscopic needle knife sinusotomy a...
Endoscopic management of anastomotic bleeding in the ileal pouch with staples r...
Wu,Xian-rui; Lan,Nan; Shen,BoOBJECTIVE: Postoperative pouch bleeding is a rare but detrimental complication following ileal pouch surgery. It is usually self-limited, however continuous bleeding requires intervention. There is limited published data on its management. DESIGN: Ileoscopy via stoma for loop ileostomy and pouchoscopy via anus for ileal pouch were performed under sedation for the purpose of diagnosis and management of postopera...
Management of ileal pouch prolapse with endoscopic hot snare
Wu,Xian-rui; Liu,Xiu-li; Lan,Nan; Shen,BoPouch prolapse is a complication following the creation of restorative proctocolectomy. There is a paucity of information in the literature pertaining to its management. An ileal J pouch patient with dyschezia presented to our Pouch Center. Under sedation, pouchoscopy was performed with a gastroscope. We detected an anterior distal pouch mucosal prolapse, 1.5 cm in diameter, blocking the anal canal. The prolaps...
CHRNA5 polymorphism and susceptibility to lung cancer in a Chinese population
Shen,Bo; Zhu,Qun; Zheng,Ma-Qing; Chen,Jia; Shi,Mei-Qi; Feng,Ji-FengPolymorphisms in the nicotinic acetylcholine receptor subunit CHRNA5 gene have been associated with lung cancer positive susceptibility in European and American populations. In the present hospital-based, case-control study, we determined whether polymorphism in rs503464 of CHRNA5 is associated with lung cancer risk in Chinese individuals. A single nucleotide polymorphism in CHRNA5 rs503464, c.-166T>A (hereafte...
