Hepatocellular carcinoma (HCC) is one of the most common solid tumors and ranks the third leading cause of cancer mortality worldwide. The purpose of this study was to examine the expression dynamics of GOLPH3 in HCC tissue samples, and explore the correlation between GOLPH3 expression and prognosis in patients with HCC.', 'The levels of Golgi phosphoprotein 3 (GOLPH3) mRNA and protein in liver cancer cell lines and fresh tissues were determined by qRT-PCR and Western blotting. Additionally, the protein expression of GOLPH3 was detected by immunohistochemistry.', 'High GOLPH3 expression was positively correlated with serum AFP level (P=0.015) and tumor recurrence or metastasis (P=0.010). In addition, liver cancer patients with high GOLPH3 expression had significantly poorer overall survival (HR, 1.87; 95% CI, 1.19-2.94; P=0.006) and poorer disease-free survival (HR, 1.90; 95% CI, 1.21-2.98; P=0.005) than those with low GOLPH3 expression. The cumulative 5-year survival rate was only 35.19% (95% CI, 26.18%-44.20%) in the high GOLPH3 expression group, whereas it was 55.93% (95% CI, 43.26%-68.60%) in the low GOLPH3 expression group. Furthermore, multivariate Cox regression analysis demonstrated that the expression of GOLPH3, tumor size and tumor multiplicity were independent prognostic predictors for HCC patients.

Previous studies regarding the outcome of laparoscopic cholecystectomy (LC) in men have reported inconsistent findings. We conducted this prospective study to test the hypothesis that the outcome of LC is worse in men than women.', 'Between 1997 and 2002, a total of 391 consecutive LCs were performed by a single surgeon at King Fahd Hospital of the University. We collected and analyzed data including age, gender, body mass index (kg/m(2)), the American Society of Anesthesiologists (ASA) class, mode of admission (elective or emergency), indication for LC (chronic or acute cholecystitis [AC]), comorbid disease, previous abdominal surgery, conversion to open cholecystectomy, complications, operation time, and length of postoperative hospital stay.', 'Bivariate analysis showed that both genders were matched for age, ASA class and mode of admission. The incidences of AC (P = 0.003) and comorbid disease (P = 0.031) were significantly higher in men. Women were significantly more obese than men (P < 0.001) and had a higher incidence of previous abdominal surgery (P = 0.017). There were no statistical differences between genders with regard to rates of conversion (P = 0.372) and complications (P = 0.647) and operation time (P = 0.063). The postoperative stay was significantly longer in men than women (P = 0.001). Logistic regression analysis showed that male gender was not an independent predictor of conversion (Odds ratio [OR] = 0.37 and P = 0.43) or complications (OR = 0.42, P = 0.42). Linear regression analysis showed that male gender was not an independent predictor of the operation time, but was associated with a longer postoperative stay (P = 0.02).

Heart rate variability in the frequency domain has been proposed to reflect cardiac autonomic control. Therefore, measurement of heart rate variability may be useful to assess the effect of epidural anesthesia on cardiac autonomic tone. Accordingly, the effects of preganglionic cardiac sympathetic blockade by segmental epidural anesthesia were evaluated in humans on spectral power of heart rate variability. Specifically, the hypothesis that cardiac sympathetic blockade attenuates low-frequency spectral power, assumed to reflect cardiac sympathetic modulation, was tested.', 'Ten subjects were studied while supine and during a 15-min 40 degrees head-up tilt both before and after cardiac sympathetic blockade by segmental thoracic epidural anesthesia (sensory block: C6-T6). ECG, arterial pressure, and respiratory excursion (Whitney gauge) were recorded, and a fast-Fourier-transformation was applied to 512-s data segments of heart rate derived from the digitized ECG at the end of each intervention.', 'With cardiac sympathetic blockade alone and the subjects supine, both low-frequency (LF, 0.06-0.15 Hz) and high-frequency (HF, 0.15-0.80 Hz) spectral power remained unchanged. During tilt, epidural anesthesia attenuated the evoked increase in heart rate (+11.min-1 +/- 7 SD vs. +6 +/- 7, P = 0.024). However, while during tilt cardiac sympathetic blockade significantly decreased the LF/HF ratio (3.68 +/- 2.52 vs. 2.83 +/- 2.15, P = 0.041 vs. tilt before sympathetic blockade), a presumed marker of sympathovagal interaction, absolute and fractional LF and HF power did not change.
