Objective To observe the effect of hot compress with medicinal salt pack in preventing PICC-associated mechanical phlebitis.Method Totally 200 inpatients undergone PICC intubation were randomized into a treatment group and a control group, 100 cases in each group. After PICC intubation, the treatment group was intervened by hot compress with medicinal salt pack, while the control group was by hot compress with warm wet towel. The occurrence of mechanical phlebitis was observed at different time points and compared between the two groups. Result The occurrence rate of mechanical phlebitis was 9.0% in the treatment group versus 26.0% in the control group, and the difference was statistically significant (P<0.05). In the treatment group, the occurrence rate of mechanical phlebitis was respectively 6.0% and 3.0% when treatment≤72 h and>72 h, versus 16.0% and 10.0% in the control group, and the differences were statistically significant (P<0.05). Conclusion Hot compress with medicinal salt pack can effectively reduce the occurrence of PICC-associated mechanical phlebitis.

Objective To investigate the mechanism of anti-epileptic effect of the curcumin .Methods The SD rats were injected intraperitoneally with pentylenetetrazol kindling 25 .0 mg/kg to induce a rat epilepsy model .All of the treatments were performed once a day continuously for 28 days .The rats in blank group and model group received 5 ml of normal saline .The rats in the high and low curcumin group were given 200 mg/kg and 100 mg/kg of curcumin once a day ,respectively .The rats in the sodium valproate (VPA) group were given 400 mg/kg of VPA once a day by gavage .After treatment ,the seizures level was recorded by using the Racine′s six point grading scale ,and the expression of IL-2 and IL-6 of hippocampus were detected by the enzyme linked immunoassay (ELISA) .Results The seizures level was reduced by curcumin in epileptic rats .The ex-pressions of IL-2 and IL-6 of the model group were significantly higher than those of the blank group (P<0 .05) ,while those rats of the anti-epileptic groups ,including high dose group and low dose group ,were lower than those rats of the model group (P<0 .05) .When compared with the curcumin low dose group ,the expression of IL-2 and IL-6 of curcumin high dose group is lower (P< 0 .05) .There was no significant difference between the high dose curcumin group and VPA group (P>0 .05) . Conclusion The curcumin can reduce the seizure level in rats ,it shows some anti-epileptic effets and dose-dependently ,which may be through down-regulating the expression of IL-2 and IL-6 in hippocampus .
