This study aims to learn about the current situation of surgical massive blood transfusion of different surgical departments in China's Tertiary hospitals, which could provide the basis for the formulation of guidelines on massive blood transfusion. ⋯ Patients undergoing massive blood transfusion among different surgical departments have a certain difference in use of blood transfusion, mortality rate and the time of death. Our findings suggested that we should set up an independent transfusion program in cardiac surgery and trauma patients of massive blood transfusion.

Non-alcoholic fatty liver disease (NAFLD) generally has a relatively favorable clinical course; however, non-alcoholic steatohepatitis (NASH) was much more frequently progresses to cirrhosis and hepatocellular carcinoma. We performed a systematic review and meta-analysis of clinical trials to examine the effects of vitamin E supplementation in improving liver histology in NASH. We performed a comprehensive search of the PubMed, Embase and Cochrane databases through October 2014. ⋯ Compared with controls, vitamin E supplementation significantly improved all histological parameters, including steatosis (WMD = -0.62, 95% CI: -0.95, -0.77, P = 0.0002), hepatocyte ballooning (WMD = -0.30, 95% CI: -0.56, -0.04, P = 0.03), lobular inflammation (WMD = -0.39, 95% CI: -0.67, -0.11, P = 0.007) and fibrosis (WMD = -0.39, 95% CI: -0.72, -0.06, P = 0.02). Our analysis also indicated the absence of publication bias between NASH and Vitamin E intake. This meta-analysis indicates that vitamin E supplementation had a significant and positive effect in the improvement of steatosis, ballooning degeneration, lobular inflammation and fibrosis in patients with NASH.

To determine functional connectivity of the default mode network in patients with sensorineural hearing loss (SNHL) in resting state. ⋯ The posterior cingulate cortex, precuneus lobe, medial frontal gyrus, anterior cingulate cortex, temporal lobe, angular gyrus and inferior parietal lobule constitute a default mode of network in normal resting status. And patients with SNHL have abnormal functional connectivity of default mode network and cortical reorganisation in resting status.

Both target radiofrequency thermocoagulation and collagenase chemonucleolysis are effective micro-invasive therapy means for lumbar intervertebral disc herniation. In order to analyze the clinical effects of target radiofrequency thermocoagulation combined with collagenase chemonucleolysis on lumbar intervertebral disc herniation, the contents of hydroxyproline and glycosaminoglycan were measured and the histological changes of nucleus pulposus was detected in the vitro experiments. Radiofrequency thermocoagulation reduced the hydrolyzation of herniated nucleus pulposus caused by collagenase, as well as the content of hydroxyproline and glycosaminoglycan. ⋯ In the post-operative follow-up exam, 86.8% of the re-examined cases demonstrated smaller or ablated protrusion, with reduced IDH values from pre-operation, which was statistically significant. No serious complications were detected intra-operatively and post-operatively. In conclusion, target radiofrequency combined with collagenase chemonucleolysis was an effective and safe method for treatment of lumbar intervertebral disc herniation.

Early post-operative mobilization is important both to reduce immobility-related complications and to get the best functional result following surgery on knee. We hypothesized that saphenous nerve block would reduce pain in this patient category compared with placebo injection. In this study, two reviewers independently searched the databases of PubMed, EMBASE, and Cochrane Library (last performed on 12 October, 2014) to retrieve eligible randomized controlled clinical trials. ⋯ In addition, compared to placebo injection group, saphenous nerve block resulted in significantly less morphine consumption during the first postoperative 24 hours (MD = -6.56; 95% CI -11.26 to -1.86; P = 0.006). To conclude, this meta-analysis suggests that saphenous nerve block has an advantage in pain relief both at an active flexion of knee and at rest after knee surgery. Further studies are still wanted to validate these conclusions.
