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 explore the role of 6-CYANO-2,3-DIHYDROXY-7-NITROQUIN OXALINE (CNQX) in different types of synapse secretion.Methods:The spontaneous mEPSCs and eEPSCs at different extracellular concentrations of CNQX in cultured cortical or hippocampal neurons were recorded respectively.Results:The half inhibitory concentration (IC50) of CNQX in evoked neurotransmitter release was significantly higher than that of spontaneous release,indicating that the spontaneous neurotransmitter release was more sensitive to CNQX.No apparent difference was observed between cortical and hippocampal cells,suggesting that the blocking effect of CNQX was similar in different brain regions.Conclusion:CNQX might have differential regulating mechanisms between excitatory spontaneous and evoked neurotransmitter release,but without brain regions specificity.

Objective To discuss the optimal retrieval time of the indwelling Gunther Tulip and Cook Celcet inferior vena cava filters (VCF). Methods During the period from March 2013 to April 2015 at Shengli Oilfield Central Hospital, the implantation of retrievable inferior vena cava filter was performed in 58 patients. Among the 58 patients, Gunther Tulip VCF was used in 13 and Cook Celcet VCF was employed in 31. Twenty-one patients followed the doctor's advice to receive retrieval procedure of VCF within three months after the implantation. Results Among the 21 patients, successful retrieval of VCF was obtained in 19. The mean indwelling time of Gunther Tulip VCF was 54.4 days, the longest time being 79.0 days. Gunther Tulip VCF was successfully removed in 3 patients and retrieval of VCF failed in 2 patients, with a retrieval success rate of 60%. The mean indwelling time of Cook Celcet VCF was 37.6 days, the longest time being 67.0 days. Cook Celcet VCF was successfully removed in 16 patients, with the success rate of retrieval being 100%. Conclusion Despite many VCFs that have been indwelled for a long time can be safely retrieved, retrieval procedure should be performed as early as possible in order to improve the retrieval success rate of VCF. It seems that the use of Cook Celcet VCF is a better choice although it is more expensive.
