Randomized Controlled TrialGinsenoside Rg3 inhibits HIF-1α and VEGF expression in patient with acute leukemia via inhibiting the activation of PI3K/Akt and ERK1/2 pathways.
Aberrant angiogenesis is essential to the development and progression of leukemia. Ginsenoside Rg3 has been commonly used in anti-angiogenic therapy of solid tumors. This study aimed to investigate the anti-angiogenic effects of Rg3 in patients with acute leukemia. ⋯ In addition, Rg3 treatment led to reduced serum levels of HIF-1α and VEGF in patients with acute leukemia. Mechanistically, we demonstrated that Rg3 downregulated the phosphorylation of Akt and ERK1/2 in BMSCs. In conclusion, Rg3 exhibits anti-leukemia effect in part due to its anti-angiogenic activity via inhibiting PI3K/Akt and ERK1/2 pathways, which act to regulate the expression of HIF-1α and VEGF.

Neutrophil CD64 expression is a predictor of mortality for patients in the intensive care unit.
Neutrophil CD64 has been shown to be a promising biomarker for bacterial infection and sepsis identification. However, the prognostic value of CD64 in predicting the likelihood of survival for patients in intensive care unit (ICU) is unclear. ⋯ CD64 had the greatest power for predicting ICU mortality other than APACHE II scores. This result indicates that CD64 may be used as a biomarker to in combination with the use of APACHE II scores to improve the accuracy of predicting mortality outcome for patients in the ICU.

Clinical significance of NQO1 polymorphism and expression of p53, SOD2, PARP1 in limited-stage small cell lung cancer.
Small cell lung cancer (SCLC) is one of highly aggressive cancers with poor prognosis. Unfortunately, there are as yet no molecular targets that can be exploited to prolong survival in patients with SCLC. This study aimed to investigate possible molecular markers associated with prognosis in limited-stage small cell lung cancer (LS-SCLC). ⋯ PARP1 expression is correlated with longer progression-free survival in LS-SCLC requiring further studies to clarify the precise role of PARP1 and the relevance of PARP1-targeted therapy.

Case ReportsMeningitis and pneumococcal pyomyositis in a child with intramuscular hemangiomas: an autopsy case report.
Pyomyositis is the bacterial infection of skeletal muscle, usually accompanied by abscesses. The main etiologic agent is Staphylococcus aureus. ⋯ The authors propose the hypothesis that patients with hemangiomas, mainly the intramuscular type, may also represent a risk group for pyomyositis. The possibility of respiratory/meningeal co-infection, might also be considered even if the clinical picture is restricted to the muscular system.

Case ReportsMast cell leukemia with prolonged survival on PKC412/midostaurin.
Mast cell leukemia (MCL) is a rare and aggressive form of systemic mastocytosis. There are approximately 50 reported cases since 1950s. MCL is refractory to cytoreduction chemotherapy and the average survival is only six months. ⋯ Since then, her disease had been stably controlled. This is the first report of a high-tumor-load MCL case which achieved prolonged survival (101 months) by PKC 412. The 101-month overall survival is the longest among reported MCL cases in the English literature.
