Anatomic versus non-anatomic resection of hepatocellular carcinoma with microvascular invasion: A systematic review and meta-analysis.

The efficacy of anatomical resection (AR) and non-anatomical resection (NR) in the treatment of hepatocellular carcinoma (HCC) patients with microvascular invasion (MVI) remains unknown. This study compared the safety and outcomes of these surgical procedures. A systematic literature search was conducted.

[Influence of Spectral Pre-Processing on PLS Quantitative Model of Detecting Cu in Navel Orange by LIBS].

Cu in navel orange was detected rapidly by laser-induced breakdown spectroscopy (LIBS) combined with partial least squares (PLS) for quantitative analysis, then the effect on the detection accuracy of the model with different spectral data ptetreatment methods was explored. Spectral data for the 52 Gannan navel orange samples were pretreated by different data smoothing, mean centralized and standard normal variable transform. Then 319~338 nm wavelength section containing characteristic spectral lines of Cu was selected to build PLS models, the main evaluation indexes of models such as regression coefficient (r), root mean square error of cross validation (RMSECV) and the root mean square error of prediction (RMSEP) were compared and analyzed.

[Determination of soluble solids content in navel oranges by Vis/NIR diffuse transmission spectra combined with CARS method].

Soluble solids content (SSC) is one of important internal quality index for navel oranges. In the present study, visible/near infrared (Vis/NIR) diffuse transmission spectra of navel oranges were acquired using a QualitySpec spectrometer in the wavelength range of 350-1 000 nm, and CARS (competitive adaptive reweighted sampling) was used to select important variables related with SSC of navel oranges from spectra data, then was compared with other variable selection methods such as uninformative variables elimination (UVE) and successive projections algorithm (SPA). Finally, partial least squares (PLS) regression was used to develop calibration model for SSC of navel oranges using the 38 selected variables, and the calibration model was used to predict the SSC of 75 samples in the prediction set.

Effect of hyperbaric oxygen and ulinastatin on plasma endotoxin, soluble CD14, endotoxin-neutralizing capacity and cytokines in acute necrotizing pancreatitis.

Background: We sought to study the effect of a combination therapy comprised of hyperbaric oxygen (HBO) and ulinastatin on the plasma levels of endotoxin, soluble CD14 (sCD14), endotoxin neutralizing capacity (ENC) and cytokines in acute necrotizing pancreatitis (ANP) in rats.

Methods: We randomly allocated 90 Sprague-Dawley rats into 6 groups: group 1 (ordinary control), group 2 (sham operation), group 3 (ANP), group 4 (ANP with HBO), group 5 (ANP with ulinastatin) and group 6 (ANP with HBO and ulinastatin). We induced ANP by retrograde injection of 3.
