ABSTRACT

For the safety problems of internal medicine intravenous infusion,we carry out meticulous management,establish quality control system of intravenous infusion safety management,and formulate quality control plan.We collect and analyse the potential unsafety factors in the various departments of internal medicine.We have revised the intravenous infusion system and procedures,formulated standards for safety inspection of intravenous fluids,and standardized the admission system for nurses.We carry out training on intravenous infusion related knowledge for nursing staff,carry out meticulous management of venous transfusion links,and actively carry out learning and communication.All these measures have greatly enhanced the safety awareness of the nursing staff.The safety index of intravenous infusion for liver diseases was preliminarily summarized.The use rate of the safe indwelling needle was increased from 30.60% to 92.30%,the rate of appropriate rate of drop speed increased from 68.45% to 93.20%,the three sign standard rate rose from 75.20% to 95.10%,and the patient's satisfaction with infusion increased from 85.60% to 96.82%.Meticulous management can improve the safety of the internal medicine intravenous infusion as a whole.

ABSTRACT

ObjectiveTo investigate the effect of NGF on apoptosis of HSC in vitro and explore the possible mechanism.MethodsHSC was incubated with different concentrations of NGF.HSC apoptosis was identified by FCM.The expressions of apoptosis-regulating proteins Caspase-3,p53 and Bcl-2 of HSC after apoptosis induced by NGF were examined by immunohistochemical staining.Expressions of NGF and p75NTR were detected by immunofluorescence.ResultsApoptosis index of HSC was higher than that of control group [(22.36±9.51)% vs (5.88±1.36)%] after treated with NGF (100 ng/ml) (P<0.05).After incubating with 100 ng/ml NGF for 24 h,the positive expression rates of p53 and Caspase-3 of HSC increased significantly than those of control group [(78.41±4.00)% vs (34.96±3.84)%,(39.26±1.57)% vs (9.27±1.01)%,P <0.05].The positive expression rate of Bcl-2 protein of HSC significantly decreased compared with that of control group (18.12±1.38)% vs (91.53±2.98)% (P<0.05).When HSC was stimulated with 100 ng/ml NGF for 24 h,the average optical density of NGF increased significantly than control group (6.53±1.40 vs 1.77±0.17) (P<0.05),while the expression of p75NTR was not significantly changed (3.52±0.36 vs 4.24±0.38) (P>0.05).ConclusionsThe mechanism of NGF to induce HSC apoptosis may be associated with the up-regulating expression of Caspase3,P53 and down-regulating expression of Bcl-2 on HSC.NGF could be used as an initiating factor and effect factor to increase the expression of NGF on HSC,but it had no significant effect on p75NTR expression.
