Randomized Controlled Trial Comparative StudyLow tidal volume with PEEP and recruitment expedite the recovery of pulmonary function.
The potentially harmful effects of short-term mechanical ventilation during surgery have been examined in recent years. An optimal strategy for mechanical ventilation of patients during non-laparoscopic abdominal surgery must be devised. A total of 63 patients undergoing elective open abdominal surgery with more than 2 h of ventilation time were selected for this randomized, open-label, clinical study. ⋯ There were no significant differences in FEV1 or FVC among the three groups (P=0.32 and 0.09, respectively), but both of these measurements showed different changes over time (group effect over time P<0.001). On the first postoperative day, the low volume with high PEEP and recruitment group had significantly higher FEV1 than the other two groups (mean ± SD): 1.52 ± 0.37 versus 0.95 ± 0.38 (P<0.001) and 1.52 ± 0.37 versus 0.95 ± 0.34 (P<0.001), respectively. Low tidal volume with PEEP and recruitment showed advantages in maintaining the pulmonary compliance and expediting the recovery of the 1(st) postoperative day's pulmonary function in patients undergoing non-laparoscopic abdominal surgery.

Review Case ReportsMyxoid epithelioid gastrointestinal stromal tumor harboring an unreported PDGFRA mutation: report of a case and review of the literature.
Activating mutations of platelet-derived growth factor receptor α (PDGFRA) are detected in a significant proportion of gastrointestinal stromal tumors (GISTs), in addition to the more frequent mutation in c-kit. GISTs with PDGFRA mutations have been found to have several characteristic morphological features, sometimes allowing to discriminate them from GISTs with c-kit mutations. Among these, epithelioid morphology in tumor cells and tumor-infiltrating mast cells are powerful predictors of PDGFRA mutations. ⋯ The existence of a similar mechanism in eosinophil and mast cell recruitment via tumor-producing stem cell factor is speculated. Mutational analyses revealed a PDGFRA exon 18 mutation: D842_H845del, D846N. Combined deletion and substitution mutation has been reported in rare instances, but to the best of our knowledge, D846N has not been documented.

Factors influencing the spontaneous closure of ventricular septal defect in infants.
This study is to prospectively evaluate the potential value of maternal and infantile variables as predictors for the spontaneous ventricular septal defects (VSD) closure in infants. ⋯ DVSD, DVSD/DAR, left atrium sizes, left ventricle sizes, main pulmonary forward blood flow, infection scores, Qp/Qs, VSD location, comorbidities including PDA, or membranous septal aneurysm may be used as potential independent predictors of spontaneous VSD closure in infants.

Randomized Controlled TrialImmunomodulatory effect of DC/CIK combined with chemotherapy in multiple myeloma and the clinical efficacy.
To investigate the clinical efficacy of adoptive immunotherapy using dendritic cells (DC) and cytokine-induced killer (CIK) cells combined with chemotherapy in multiple myeloma. The immunomodulatory effect of the therapy was discussed by detecting the levels of peripheral blood T cell subsets and CD4(+)CD25(+) regulatory cells (Treg). Fifty MM patients were randomly divided into two groups: 24 cases in the simple chemotherapy group and 26 cases in the combined therapy group (chemotherapy plus DC/CIK immunotherapy). ⋯ The CD3(+)CD4(+)/CD3(+)CD8(+) ratio, AgNOR ratio, IL-2 and IFN-γ level and positive rate of NKG2D in the combined therapy group were significantly higher than those of the simple chemotherapy group (P<0.05). These results indicated better immunomodulatory effect of the combined therapy. DC/CIK immunotherapy combined with chemotherapy has a good clinical efficacy and prospect for MM, reversing the Th1 to Th2 shift and increasing the anti-tumor capacity of the immune system.

Comparative StudyExpression of Yes-associated protein (YAP) in metastatic breast cancer.
The purpose of this study was to investigate the expression of Yes-associated protein (YAP) in different metastatic sites in metastatic breast cancer and to determine the clinical implications of these patterns. Immunohistochemical staining was used to investigate the expression of YAP and phospho-YAP in tissue microarrays from 122 cases of metastatic breast cancer (bone metastasis = 29, brain metastasis = 38, liver metastasis = 12, and lung metastasis = 43). The expression levels of YAP and phospho-YAP differed according to the metastatic site in metastatic breast cancer. ⋯ This analysis showed that nuclear YAP positivity (P = 0.008) and nuclear phospho-YAP positivity (P = 0.003) were both associated with shorter overall survival. In conclusion, the level of YAP expression varies according to the metastatic site in metastatic breast cancer. Moreover, high YAP expression was correlated with poor prognosis.
