BACKGROUND Proximal femoral nail anti-rotation (PFNA) is a standard femoral intertrochanteric fracture operation. Iatrogenic vascular injury, although uncommon, is a reported complication of PFNA surgery as well as a complication of hip fracture surgery. This study aimed to compare the safety and best use of the distal locking screw in 170 mm PFNA and 240 mm PFNA devices, and to determine the safe region for placement of the distal locking screw in PFNA surgery. ⋯ The short nails (170 mm PFNA-II devices) were the closest to the DFAs region, indicating that the 170 mm PFNA-II nails are most likely to cause special vessel injury. The short nails were relatively more distant from the SFAs, which were located posteriorly to the long nails (240 mm PFNA-II). CONCLUSIONS The distal locking screw of the 170 mm PFNA device was more prone to damage the femoral deep artery when the two types of PFNA devices are compared in patients who were candidates for both types of devices.

BACKGROUND The abnormal activity of Sirtuin 1 (Sirt1) is closely related to the aging of vascular endothelial cells. As a bioactive molecule, allicin has antioxidant, anti-inflammatory, and lipid-regulating mechanisms. However, few reports about the relationship of allicin and Sirt1 have been published. ⋯ These effects were significantly alleviated by 5 ng/mL allicin co-treatment. Furthermore, the anti-aging effects of allicin were abolished by the Sirt1 inhibitor nicotinamide (NAM). CONCLUSIONS Overall, the results demonstrated that allicin protects HUVECs from H2O2-induced oxidative stress and aging via the activation of Sirt1.

BACKGROUND We compared the factors that might impact the severity and the prognosis of carbamazepine (CBZ) intoxication in children, as well as the efficacy levels of the treatment options. MATERIAL AND METHODS Demographic information and clinical and laboratory findings for 40 patients were evaluated retrospectively. Predictive parameters for the development of serious complications were studied. ⋯ A significantly negative correlation was found between the serum CBZ level and the GCS score, but the serum CBZ level was found to be significantly positively correlated with the lactate level. CONCLUSIONS According to our study, the GCS score at admission to hospital, the serum CBZ, glucose, pH, and lactate levels, and body temperature might be useful in predicting serious CBZ intoxication and prognosis in pediatric cases. We conclude that invasive treatment methods, such as hemodialysis or albumin-enhanced continuous venovenous hemodialysis, should be used in patients who do not respond to supportive treatment.

BACKGROUND The aim of this study was to examine the association between serum expression of miRNA-155 and postoperative cognitive dysfunction (POCD) after laparoscopic surgery for colon cancer. MATERIAL AND METHODS We enrolled 110 patients scheduled to undergo colon tumor resection via laparotomy in Ningbo No. 2 Hospital from July 2013 to November 2015. The blood samples were collected from the participants 1 day before surgery. ⋯ Age, MMSE score, duration of surgery and anesthesia, serum levels of CRP, TNF-α, urea, creatinine, and miRNA-155 were highly associated with the occurrence of POCD. Serum expression of miRNA-155 was shown by multiple logistic regression analysis to be an independent predictive indicator for POCD after surgery (OR: 2.732; 95%CI 1.415-5.233; P=0.002). CONCLUSIONS The serum expression of miRNA-155 is an independent predictive factor for POCD after laparoscopic surgery for colon cancer.

BACKGROUND In recent years there have been attempts to treat sepsis using various methods of extracorporeal blood purification in order to eliminate selected mediators of inflammation. MATERIAL AND METHODS This retrospective study assessed 28 patients (17 males, 11 females, age 60.3 ± 14.5 years) in septic shock, treated with continuous venovenous hemodialysis (CVVHD). Oligoanuric patients with acute kidney injury were qualified for 24-hour CVVHD using high cut-off (HCO) hemofilter. ⋯ The rise of IL-6 during HCO-CVVHD significantly correlated with mortality due to sepsis. CONCLUSIONS Continuous venovenous hemodialysis using high cut-off hemofilter proved to be effective in the removal of IFN-α, IL-1β, IL-2 and IL-6, IL-10 and IL-12 from serum in patients during septic shock. The rise of IL-6 during HCO-CVVHD seems to be a marker of bad prognosis in septic shock patients.
