RESUMO

Objective The Zinc fingers and homeoboxes (ZHX) protein family has been reported to be involved in tumor development; however, it remains controversial whether these proteins can act as promoters or inhibitors of cancer development. The current study focused on the biological role of ZHX2 in ovarian cancer. Methods Tissue microarrays were established using 154 ovarian cancer samples. Immunohistochemical analysis was employed to determine the expression levels of ZHX2 in ovarian cancer samples. The prognostic analysis was performed using the Kaplan–Meier method and compared with a log-rank test. The specific role of ZHX2 in ovarian cancer was investigated in cell lines in vitro. Results It was found that ZHX2 was not significantly overexpressed in ovarian cancer samples; however, its expression was significantly correlated with advanced tumor grade. Patient survival analysis indicated that patients with high expression of ZHX2 exhibited worse overall survival rate compared with those with low expression of ZHX2. Furthermore, univariate and multivariate analyses demonstrated that ZHX2 was an independent prognostic factor of progression-free survival in patients with ovarian cancer. In vitro experiments indicated that inhibition of ZHX2 could significantly suppress ovarian cancer cell proliferation via induction of the apoptotic pathway. Conclusions The data indicated that ZHX2 may be considered a promising biomarker in ovarian cancer and that inhibition of its expression may be a potential therapeutic target in ovarian cancer treatment (AU)

RESUMO

The authors aimed to explore the association between visit-to-visit blood pressure variability (BPV) in pregnant women and adverse neonatal outcomes. The study included 52 891 pregnant women. BPV was calculated as standard deviation (SD) and coefficient of variation (CV) of systolic blood pressure (SBP) or diastolic blood pressure (DBP). All participants were divided into four groups by the quartiles of BPV. When comparing the highest quartiles to the lowest quartiles of DBP SD in all participants, the fully adjusted ORs were 1.19 (95% CI 1.11-1.27, p for trend < .001) for fetal distress, 1.32 (95% CI 1.14-1.54, p for trend < .001) for small for gestational age, 1.32 (95% CI 1.06-1.63, p for trend = .003) for 1-min Apgar score ≤ 7. When comparing the highest quartiles to the lowest quartiles of DBP CV, ORs were 1.22 (95% CI 1.14-1.30, p for trend < .001) for fetal distress, 1.38 (95% CI 1.17-1.61, p for trend < .001) for small for gestational age, 1.43 (95% CI 1.14-1.79, p for trend < .001) for 1-min Apgar score ≤ 7. ORs for preterm birth and 5-min Apgar score ≤ 7 were not statistically significant. However, in participants with gestational hypertension or preeclampsia, ORs for preterm birth were 2.80 (95% CI 1.99-3.94, p for trend < .001) in DBP SD and 3.25 (95% CI 2.24-4.72, p for trend < .001) in DBP CV when extreme quartiles were compared. In conclusion, higher visit-to-visit BPV was associated with adverse neonatal outcomes.

RESUMO

ZrW2O8/ZrO2 composites with tunable low/near-zero coefficients of thermal expansion (CTE) are promising candidates in several fields including aerospace, precision manufacturing and measurement, electronic circuit, etc., for counteracting the thermal expansion effect. However, bottleneck issues (such as the unstable decomposition of ZrW2O8 phase, manufacturing size limitation, etc.) caused by conventional high-temperature sintering impede the development and application of ZrW2O8/ZrO2. To solve these scientific issues, a methodology integrating hydrothermal assembly with a cold sintering process (CSP) is exploited. The ZrW2O8/ZrO2 composite powders with a mace-like structure, in which the spherical ZrO2 nanoparticles peripherally embed on the rod-like ZrW2O8 matrix particles, are hydrothermally assembled. Then, the relatively dense ZrW2O8/ZrO2 composites with excellent low or even near-zero CTE are successfully achieved by CSP (as low as 190 °C) with a postannealing treatment (550 °C). The evolution of sintering densification, phase composition, and microstructure followed by the fundamental mechanism regarding the hydrothermal assembly of the mace-like structure and densification of CSP are investigated in detail. This research not only effectively overcomes the bottleneck issues of ZrW2O8/ZrO2 via integrating the hydrothermal assembly with the sintering technology at ultralow temperature but also develops a promising prospect for the fabrication of a broader range of metastable functional materials.

RESUMO

This study was performed to assess the probability of post-thrombotic syndrome (PTS) after treatment of lower extremity deep venous thrombosis (LEDVT). Patients with LEDVT undergoing their first treatments in Nanjing First Hospital from January 2013 to December 2014 were enrolled in this study (156 patients were enrolled in the training cohort, and 135 patients were enrolled in the validation cohort). 51 and 45 patients developed PTS in the two cohorts, respectively. Independent risk factors for PTS were investigated in the training cohort, and these independent risk factors were employed to develop the APTSD scoring system with which to predict the probability of PTS. Four independent risk factors for PTS were identified: iliac vein compression syndrome, residual iliac-femoral vein thrombosis, residual femoral-popliteal vein thrombosis and insufficient anticoagulation. Patients in the training cohort were divided into 2 groups according to the APTSD score of ≤7.0 and >7.0 points regarding the probability of PTS (median PTS-free time, 21.82 vs. 18.84 months; P < 0.001). The accuracy of this score system was 81.7% for the training cohort and 82.5% for the validation cohort. Patients with an APTSD score of >7.0 points may have an increased probability of developing PTS.
