OBJECTIVE: To investigate the mechanism that cucurmosin (CUS) induces the apoptosis of human pancreatic cancer cell line CFPAC-1. METHODS: The inhibition effect of cucurmosin on CFPAC-1 cell was detected by MTT assay. The apoptosis was observed by transmission electron microscope. The cell cycle and apoptosis rate were analyzed by flow cytometry. The expressions of caspase-3 and bcl-2 protein were determined by Westernblot. RESULTS: After CFPAC-1 cells were treated with cucurmosin of 0.03125, 0.0625,0.125,0.25,0.5, 1 and 2 μmol · L-1 for 24,48 and 72 h, the proliferation of CFPAC-1 cells was inhibited in a time- and dose- dependent manner(P<0.05). After CFPAC-1 cells were treated with 1 μmol · L-1 cucurmosin for 72 h, typical apoptosis changes were observed under transmission electron microscope. Compared with control group, more cells were arrested at G0/G1 phases (P<0.05) and fewer cells were at S phases(P<0.05). CUS decreased the speed of cell-cycle progression from G0/G1 phase into S phase. After CFPAC-1 cells were treated without(control) or with cucurmosin of 0.062 5,0.25 and 1 μmol · L-1 for 72 h, the apoptosis rates of CFPAC-1 cells were (0.33±0.37)%, (19.26±1.49)%,(37.13±2.07)% and (55.64±2.91)%, respectively. The expression of caspase-3 was elevated, whereas the expression of Bcl-2 was lessened gradually. CONCLUSION: Cucurmosin induces the apoptosis of pancreatic cancer CFPAC-1 cells through up-regulating the expression of caspase-3 and down-regulating the expression of bcl-2.

Evidence body is defined as an evidence complex incorporating the evidence obtained from various research methods and various resources. As one of common parenterally administered Chinese medicines, Shuxuetong's safety drew high concern from doctors. However, we only have grasped several but less systematic evidence on the safety of Shuxuetong. To build a safety evidence body of Shuxuetong injection. Review and evaluate the evidence related to the safety of Shuxuetong injection after accumulating, searching and classfying related literature. Accoeding to levels of evidence from high to low, the evidence related to the safety of Shuxuetong injection was classified as following: the evidence from a long-term, prospective, large-sample-size and intensive hospital monitoring study was the strongest; the evidence of hospital information system (HIS) data analysis; the evidence of spontaneous reporting system (SRS) data analysis; the evidence of adverse drugreactions (ADRs)/adverse drug events (ADEs) reported in systematic evaluation, ADRs case report, toxicological tests, pharmacological tests were weakest. Based on the evidence body, Shuxuetong Injection was proved to be safe, and its ADRs were mainly allergic reactions, and more often happened among the old patients.
