Aim. To investigate clinical significance of runt-related transcription factor (RUNX)-2 in epithelial ovarian cancer (EOC). Methods. RUNX2 protein expression and its subcellular localization were detected by immunohistochemistry in 116 patients with EOC. Results. RUNX2 protein was predominantly expressed in cell nucleus of EOC tissues. The expression level of RUNX2 in EOC tissues was significantly higher than that in normal ovarian tissues (P < 0.001). In addition, the nuclear labeling index (LI) of RUNX2 in tumor cells was significantly associated with the advanced clinical stage of EOC tissues (P = 0.001). Moreover, EOC patients with high RUNX2 LI had significantly shorter overall (P < 0.001) and progression-free (P = 0.002) survival than those with low RUNX2 LI. Especially, subgroup analysis revealed that EOC patients with high clinical stages (IIIIV) in high RUNX2 expression group demonstrated a significantly worse clinical outcome than those in low RUNX2 expression group, but patients with low clinical stages (III) had no significantly different prognosis between high and low RUNX2 expression groups. Conclusions. Our data suggest for the first time that RUNX2 overexpression is associated with advanced tumor progression and poor clinical outcome of EOC patients. RUNX2 might be a novel prognostic marker of EOC. © 2012 Weiping Li et al. Source

To analyze the anesthetic management for neurosurgery using intraoperative magnetic resonance imaging (iMRI). Thirty patients with intracranial tumor received MRI for preoperative safety screening and the operation was performed with general anesthesia and support by MRI-compatible machines. The operative time, frequency and duration of MRI, MRI-related time (from the preparation for MRI to the beginning of the surgery), time delay by MRI, body temperature at the initial iMRI and special issues related to the scanning and perioperative anesthesia were recorded. Thirty patients successfully completed the operations without any incidents related to anesthesia or scanning. The mean frequency of MRI was 1.8, the mean duration of MRI was 29.24 ∓ 10.10 min, and the MRI-related time was 43.83 ∓ 10.23 min; the time delay MRI was 92.63 ∓ 28.31 min, and the body temperature was significantly higher at 2 h after MRI than that after induction. In the anesthetic management for neurosurgery with iMRI, the anesthesiologists should focus on the safety precaution and anesthetic modulation according to the special environment and procedure of iMRI.

Background: Geriatric patients with femoral neck fracture (FNF) have unacceptably high rates of postoperative complications and mortality. The purpose of this study was to compare the effects of epidural anesthesia versus peripheral nerve block (PNB) on postoperative outcomes in elderly Chinese patients with FNF. Methods: This retrospective study explored mortality and postoperative complications in geriatric patients with FNF who underwent epidural anesthesia or PNB at the Chinese People’s Liberation Army General Hospital from January 2008 to December 2012. The electronic database at the Chinese People’s Liberation Army General Hospital includes discharge records for all patients treated in the hospital. Information on patient demographics, preoperative comorbidity, postoperative complications, type of anesthesia used, and in-hospital, 30-day, and 1-year mortality after surgery was obtained from this database. Results: Two hundred and fifty-eight patients were identified for analysis. The mean patient age was 79.7 years, and 71.7% of the patients were women. In-hospital, 30-day, and 1-year postoperative mortality was 4.3%, 12.4%, and 22.9%, respectively, and no differences in mortality or cardiovascular complications were found between patients who received epidural anesthesia and those who received PNB. More patients with dementia or delirium were given PNB. No statistically significant differences were found between groups for other comorbidities or intraoperative parameters. The most common complications were acute cardiovascular events (23.6%), electrolyte disturbances (20.9%), and hypoxemia (18.2%). Patients who received PNB had more postoperative delirium (P=0.027). Postoperative acute respiratory events were more common (P=0.048) and postoperative stroke was less common (P=0.018) in the PNB group. There were fewer admissions to intensive care (P=0.024) in the epidural anesthesia group. Key factors with a negative influence on mortality were acute cardiovascular events, dementia, male sex, age, American Society of Anesthesiologists score, acute respiratory events, intensive care admission, and comorbidities. Conclusion: PNB was not associated with lower mortality or lower cardiovascular complication rates when compared with epidural anesthesia in elderly patients with FNF. © 2015 Jin et al. Source

Background and objectives: Stroke volume variation (SVV) and the pulse pressure variation (PPV) have been found to be effective in prediction fluid responsiveness especially in high risk operations. The objective of this study is to validate the ability of SVV obtained by FloTrac/Vigileo system and PPV obtained by IntelliVue MP System to predict fluid responsiveness in patients with obstructive jaundice during mechanical ventilation. Methods: Twentyfive patients with obstructive jaundice (mean serum total bilirubin 175.0 ± 120.8 μmol/L), who accepted volume expansion and were hemodynamically stable after induction of anesthesia, were included in the study. SVV and PPV were recorded simultaneously before and after an intravascular volume expansion. Patients with a stroke volume index (SVI) increase of more than 10% after volume expansion were considered as responders. Results: The agreement (mean bias ± SD) between SVV and PPV was -0.2% ± 1.56%. Before volume expansion, SVV and PPV were significantly higher in responders compared to non-responders (P<0.001, P<0.001). Significant correlation was observed between the baseline value of SVV and PPV and the percent change in SVI after fluid expansion (r=0.654, P<0.001, r=0.592, P=0.002). Area under the receiver operating characteristic curves of SVV (0.955) and PPV (0.875) were comparable (P=0.09). The optimal threshold values in predicting fluid responsiveness were 10% for SVV and 8% for PPV. Conclusion: In conclusion, SVV obtained by FloTrac/Vigileo system and PPV obtained by IntelliVue MP System was able to predict fluid responsiveness in patients with obstructive jaundice. © 2015 E-Century Publishing Corporation.

Objective: To explore the clinical value of ultrasonic surface localization in internal jugular vein catheterization. Methods: Totally 150 patients with American Society of Anesthesiologists physical status I-III who were planning to receive elective surgeries were randomized into anatomical landmark group, ultrasonic surface positioning group, and ultrasound-guided group using computed random table, with 50 cases in each group. The right internal jugular vein catheterization was performed after tracheal intubation. In the anatomic landmark group, patients were punctured using surface marks through central approach. In ultrasonic surface positioning group and ultrasound-guided group, patients were punctured with ultrasonic localization and guidance through central approach. The relationship between internal jugular vein and carotid artery, the position of the needle into the vein, the success rate of puncture, the change times of puncture point, and the complications were recorded. Results: Ultrasound scan revealed that the relationship between the right internal jugular vein and the right common carotid artery could be divided into three types: parallel (12.7%), partial overlapping (69.3%), and complete overlapping (18.0%). The average "safety distance" of jugular vein puncture was (1.15 ± 0.47) cm. The success rate of the first puncture attempt in ultrasonic surface positioning group and ultrasound-guided group were 78.0% and 82.0%, respectively, which was significantly higher than that in anatomic landmark group (22.0%) (P < 0.05), whereas the complication incidence in anatomic landmark group (12.0%) were significantly higher than those in ultrasonic surface positioning group (0) and ultrasound-guided group (0) (P < 0.05). Conclusions: Ultrasonic surface positioning applied during internal jugular vein catheterization is helpful to reveal the inner diameters as well as the origin and course of arteries and veins in the puncture and identify the abnormalities as early as possible. As a simple support technique for internal jugular vein puncture, it is suitable for clinical application. Source
