ReviewClinical considerations and therapeutic strategy for sigmoid volvulus in the elderly: a study of 33 cases.
To evaluate different types of treatment for sigmoid volvulus and clarify the role of endoscopic intervention versus surgery. ⋯ Although sigmoid volvulus causing intestinal obstruction is frequently successfully encountered by endoscopic decompression, however, the principal therapy of this condition is surgery. Only occasionally in patients with advanced age, lack of bowel symptoms and multiple co-morbidities might surgical repair not be considered.

Protection of Veratrum nigrum L. var. ussuriense Nakai alkaloids against ischemia-reperfusion injury of the rat liver.
To investigate the protective effects and possible mechanisms of Veratrum nigrum L.var. ussuriense Nakai alkaloids (VnA) on hepatic ischemia/reperfusion (I/R) injury in rats. ⋯ The results demonstrate that VnA pretreatment exerts significant protection against hepatic I/R injury in rats. The protective effects are possibly associated with enhancement of antioxidant capacity, reduction of inflammatory responses and suppressed expression of ICAM-1 and E-selectin.

Ginkgo biloba extract (EGb 761) attenuates lung injury induced by intestinal ischemia/reperfusion in rats: roles of oxidative stress and nitric oxide.
To investigate the effect of ginkgo biloba extract (EGb 761) on lung injury induced by intestinal ischemia/reperfusion (II/R). ⋯ The results indicate that EGb 761 has a protective effect on lung injury induced by II/R, which may be related to its antioxidant property and suppressions of neutrophil accumulation and iNOS-induced NO generation. EGb 761 seems to be an effective therapeutic agent for critically ill patients with respiratory failure related to II/R.

Meta AnalysisGlutamine dipeptide for parenteral nutrition in abdominal surgery: a meta-analysis of randomized controlled trials.
To assess the clinical and economical validity of glutamine dipeptide supplemented to parenteral nutrition (PN) in patients undergoing abdominal surgery. ⋯ Postoperative PN supplemented with glutamine dipeptide is effective and safe to decrease the infectious rate, reduce the length of hospital stay and improve nitrogen balance in patients undergoing abdominal surgery. Further high quality trials in children and severe patients are required, and mortality and hospital cost should be considered in future RCTs with sufficient size and rigorous design.
