Learning curve of computer-assisted navigation system in spine surgery.
Spine surgery using computer-assisted navigation (CAN) has been proven to result in low screw misplacement rates, low incidence of radiation exposure and excellent operative field viewing versus the conventional intraoperative image intensifier (CIII). However, as we know, few previous studies have described the learning curve of CAN in spine surgery. ⋯ In the long run, CAN spine surgery decreased the lumbar screw cortical perforation rate and operative time. The learning curve showed a sharp drop after 6 months of using CAN that plateaued after 12 months; which was demonstrated by both perforation rate and operative time data. Careful analysis of the data showed CAN is especially useful for less experienced surgeon to reduce perforation rate and intraoperative time, although further comparative studies are anticipated.

Anatomic relationship of the internal jugular vein and the common carotid artery in Chinese people.
Variations in position and relationship between the internal jugular vein (IJV) and the common carotid artery (CCA) may lead to inadvertent artery puncture which could be disastrous during central venous access. We demonstrated the anatomic relationship of the IJV with CCA in order to find the optimal site and avoid damage of CCA. ⋯ There are variations in the position and relationship between the IJV and CCA. It is relatively more difficult to puncture at the left side of the neck, at a lower position or in elderly patients. On the contrary, it is relatively easier to puncture at the right side, at the level of the cricoid cartilage or in younger patients.

Meta AnalysisIntensive glycemic control and macrovascular events in type 2 diabetes mellitus: a meta-analysis of randomized controlled trials.
There is no agreement as to whether intensive glucose control in type 2 diabetes can reduce the incidence of macrovascular events in these patients. We performed a meta-analysis comparing intensive glucose control or conventional glucose control in randomized controlled trials. ⋯ Control of glycemia to normal (or near normal levels) in type 2 diabetes appears to be effective in reducing the incidence of major macrovascular events, but there were no significant differences of either the mortality from any cause or from cardiovascular death between the two glycemia-control strategies.

Randomized Controlled TrialPulmonary artery perfusion with HTK solution prevents lung injury in infants after cardiopulmonary bypass.
Pulmonary artery perfusion during cardiopulmonary bypass (CPB) is a novel adjunctive method, which can minimize the lung ischemic-reperfusion injury and inflammatory response. This study evaluated the protective effect of pulmonary perfusion with hypothermic HTK solution in corrections of congenital heart defects with pulmonary hypertension. ⋯ In infants with congenital heart defects, pulmonary perfusion with hypothermic HTK solution during cardiopulmonary bypass could ameliorate lung function and reduce the inflammatory response.
