Long-term remission induced by low-dose rituximab for relapsed and refractory thrombotic thrombocytopenic purpura: A report of two cases.

Thrombotic thrombocytopenic purpura (TTP) is acquired in the majority of cases. Traditional therapy consists of plasma exchange (PEX), as well as the administration of certain immunosuppressive agents including steroids. A standard dose of rituximab (RTX) at 375 mg/m weekly for 4 consecutive weeks was recently demonstrated to have significant activity in patients with acquired TTP.

[Effects of Runing Recipe II on expressions of p53 and ras oncogene proteins and cell cycle of the transplanted Ca761 breast cancer in mice].

Objective: To explore the mechanisms of Runing Recipe II (a recipe composed of traditional Chinese herbs) in inhibiting the growth of breast cancer by observing its effects on the expressions of p53 and ras oncogene proteins and cell cycle of the transplanted Ca761 breast cancer in mice.

Methods: We established the breast cancer model by transplanting Ca761 cells in mice. The mice were randomly divided into 4 groups: normal saline control group, CTX-treated group, Runing Recipe II-treated group, and Runing Recipe II and CTX-treated group, with 12 mice in each group.
