To explore the analgesic effect of propofol combine with dezocine after painless abortion and the influence on stress hormone and hemodynamics of the patients. Methods:Totally 126 cases of patients with painless abortion in our hospital from March 2013 to March 2014 were randomly divided into the observation group and the control group with 63 ones in each. The observa-tion group was anesthetized with propofol combine with dezocine, while the control group was anesthetized only by propofol. The dosage of propofol, anesthesia effect and postoperative recovery of the patients in the two groups were compared, and the level of stress hor-mones and hemodynamic parameters before and after the surgery were also compared. Results: Compared with that in the control group, the dosage of dezocine and the score of VAS after the surgery was significantly reduced in the observation group with obviously better anesthesia effect, and the differences had statistical significance (P<0. 05). The level of Cor, NE and ACTH was significantly improved, and the level of A-I and A-II was reduced significantly in the observation group, and compared with that in the control group, the differences showed statistical significance(P<0. 05). Compared with those that in the control group, the levels of SBP, DBP and SpO2 were improved significantly and the level of HR was reduced significantly in the observation group during and after the surgery, and the differences showed statistical significance (P<0. 05). The incidence of adverse drug reactions in the observation group was significantly lower than that in the control group, and the difference had statistical significance (P<0. 05). Conclusion:Propofol combine with dezocine for the surgery of painless abortion can reduce the dosage of dezocine, improve the anesthesia effect and reduce the harem pain with lower stress hormone fluctuation, hemodynamic effect and incidence of adverse reactions.

Since continuous renal replacement therapy(CRRT) is a continuous treatment,extracorporeal anticoagulation is an important measure to ensure the success of CRRT.We briefly describe the basic principles,modes and monitoring objectives of anticoagulation in CRRT.Besides,heparin anticoagulation,anticoagulation without heparin and regional citrate anticoagulation(RCA)are presented in details.We emphasize that anticoagulation mode should be individualized,and the correct selection of anticoagulation mode and intensive clinical monitor are essential to prevent complications.

Objective To investigate the effect of tanshinone ⅡA on growth and apoptosis in human hepatoma cell line BEL 7402 in vitro . Methods The human hepatoma cell line BEL 7402 was treated with tanshinone ⅡA at various concentrations for 72 h. Cytotoxicity was evaluated by MTT assay, apoptosis related alterations in morphology ascertained by cytochemical staining(Hoechst 33258) and transmission electron microscopy(TEM). Apoptotic rate was quantified by flow cytometry (FCM). Results Tanshinone ⅡA inhibited the growth of hepatoma cells in a dose dependent manner, with IC 50 values of 6.28 ?g/ml. After treatment with 1～10 ?g/ml tanshinone ⅡA for 72 h, BEL 7402 cell apoptosis with nuclear chromatin concentration and fragmentation as well as cell shrinkage and the formation of apoptotic bodies were observed. FCM analysis showed hypodiploid peaks on histogram and the apoptotic rates at 5 ?g/ml concentration for 12, 24, 36, 48 and 72 h were (2.32?0.16)%, (3.01?0.35)%, (3.87? 0.43 )%, (6.73?0.58)% and (20.85?1.74)% respectively, which were all significantly higher than that of control group (1.07?0.13)%. Conclusion Tanshinone ⅡA can induce the apoptosis of human hepatoma cell line BEL 7402 in vitro , which may be related to the mechanism of growth inhibition of the human hepatoma cell line.
