Triptolide Inhibits Breast Cancer Cell Metastasis Through Inducing the Expression of miR-146a, a Negative Regulator of Rho GTPase.

Triptolide, an extract of , has been shown to have a potent anticancer activity. In the present study, it was found that triptolide could effectively induce apoptosis and inhibit proliferation and invasion in malignant MDA-MB-231 breast cancer cells. The study focused on its effect on inhibiting invasion, which has not been extensively reported to date.

Establishing a reference range for thromboelastograph parameters in the neonatal period.

Introduction: Acquired coagulation disorders are a common cause of neonatal bleeding. The thromboelastograph (TEG) comprehensively assesses haemostatic processes in the body. Unfortunately, the reference range of TEG parameters in the neonatal period has not yet been evaluated, which limits the use of the TEG in neonates.

[Dynamics of three kinds of nitrogen in surface water of rice field with an independent irrigation system].

Studies on the dynamics of NH4+, NO3- and TN concentrations in the surface water of paddy field with an independent irrigation system showed that the concentration of NH4+ and TN in surface water was increased to the maximum after 1day of each urea application, and then decreased rapidly with time. The ratio of NH4+/TN, NO3-/TN and (NH4+ + NO3-)/TN was increased firstly, and then decreased. NH4+ and TN could be used as the main indexes for the water pollution of the paddy field, and NO3- used as the assistant one.
