Shock and the APACHE II score within 24 hours after diagnosis of PE were independent risk factors on the prognosis of PE after the thoracic and abdominal surgery; however, the study power was limited.

SHP2, a widely expressed phosphatase, which has been linked to the initiation, progression and prognosis of various malignancies. We previously identified a new SHP2 anchorage protein Hook1 in the alveolar II epithelial cells, and it is suggested that Hook1 is a novel endogenous suppressor molecule of SHP2 phosphatase activity. Nevertheless, few studies have been mentioned the clinicopathological and prognostic relevance of SHP2 and Hook1 expression in patients with non-small cell lung cancer (NSCLC). A total of 61 patients with NSCLC receiving gemcitabine plus carboplatin chemotherapy were studied. Immunohistochemical staining was conducted to determine the protein expression of SHP2 and Hook1. The relationships between gene expression and clinical and pathological factors, as well as prognosis, were evaluated. A significant correlation was observed between the SHP2 and Hook1 expression, with a total expression rate of 71.4%. The positive expression of Hook1 in adenocarcinoma and in stage IIIb-IV was higher than that in patients with squamous (73.5% vs. 31.2%, P=0.013) and I-IIIa (75% vs. 48.8%, P=0.05), suggesting that Hook1 might act as an indicator of NSCLC status. However, no significant correlation was observed between Hook1 expression and survival time (P>0.05). In contrast, patients with negative SHP2 expression had a higher survival rate (median overall survival 68 vs. 24 months, P=0.003). Cox multivariate regression analysis showed that SHP2 was an independent indicator for overall survival (
