The aim of this study was to learn the current situation of surgical massive transfusion of death and survival groups in China, which could provide the basis for the formulation of guidelines on massive transfusion. ⋯ During massive transfusion, clinicians in 20 Chinese hospitals paid more attention to the infusion of fresh frozen plasma while making the infusion of red blood cells. However, they paid little attention to the supplement of platelet and cryocepitate. The average quantity of plasma and platelet in survival group were also higher than those in death group.

Locking of central venous catheters with heparin is an accepted practice to maintain catheter patency between dialysis sessions. However, this practice may cause other adverse reactions. Although many studies suggest benefits of other catheter lock solutions over heparin on these grounds, no consensus has been reached for clinical practice. ⋯ Compared with heparin, antimicrobial-containing lock solutions more effectively prevent CRB and clinical sepsis. Antibiotics + heparin and gentamicin + citrate solutions showing better prevention of CM. Citrate-alone lock solutions result in fewer CRB, bleeding and ESI episodes.

The purpose of this study was to explore the effects of three different ventilatory modes: volume controlled ventilation (VCV), pressure controlled ventilation (PCV) and pressure controlled ventilation-volume guaranteed (PCV-VG) on arterial oxygenation and airway pressure during one-lung ventilation (OLV) in elderly patients. ⋯ Compared with VCV, the use of PCV and PCV-VG have a significant advantage in intraoperative oxygenation and airway pressure for eldly patients undergoing OLV.

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.
