ABSTRACT
Longgu is the fossil of ancient mammals which was used as a common kind of mineral medicine. Longgu is always used to treat neurological diseases. Currently, the quality standard of Longgu is incomplete. Moreover, because of the non-renewable nature of the resource and the increase of national protection of fossils, the clinical application of Longgu is facing a series of problems. As the discovery of the ingredient and the development of forging technology researchers launched to search the substitutes of Longgu. The article summarizes the usage and the study of Longgu, in order that we can discuss the modern usage and substitutability of Longgu.
ABSTRACT
Objective To evaluate the effects of home visiting on care burden and positive experience in caregivers of cerebral apoplexy patients.Methods The recruited 80 caregivers of cerebral apoplexy patients were randomly divided into the experimental group and the control group,with 40 cases in each group;the experimental group received nursing intervention of home visiting,while the control group received routine nursing guidance.Zarit Caregiver Burden Interview (ZBI) and Positive Aspects of Caregiver (PAC) were used to evaluate the care burden and positive experience in caregivers of cerebral apoplexy patients after 24 weeks.Results After the intervention,the burden of care of caregivers in the experimental group was significantly lower and the positive experience in the experimental group was significantly higher than those in the control group,and the differences were both statistically significant (P＜0.01).Conclusion Nursing intervention of home visiting can decrease caregiver burden and increase positive experience of caregivers of cerebral apoplexy patients.
ABSTRACT
Objective To analyse the characteristics of fundus fluorescein angiography(FFA)of iatrogenic retinal vascular occlu- sion.Design Retrospective case series.Participants 9 eyes of 9 patients with iatrogenic retinal vascular occlusion and 16 eyes of 16 patients with non-iatrogenic retinal vascular occlusion in Beijing Tongren Hospital in 2002-2005.Methods All patients were examined with FFA.The difference of circulation time of retinal vessels both in iatrogenic and non-iatrogenic retinal vascular occlusion patients was compared.Main Outcome Measures The starting perfusion time and the finishing time of retinal artery or vein.Results In pa- tients with iatrogenic(4 cases)and non-iatrogenic(12 cases)central retinal artery occlusion,the finishing perfusion time was separately 79.33?87.04s and 19.20?4.61s; the finishing time of retinal vein was separately 128.07?149.11s and 33.16?15.34s.In iatrogenic(4 cas- es)and non-iatrogenic(4 cases)central retinal artery together with central retinal vein occlusion patients,the finishing perfusion time of retinal artery was separately 211.67?371.26s and 30.07?17.26s;the finishing perfusion time of retinal vein was 232.43?358.52s and 48. 81?11.64s.One patient was ocular artery occlusion.FFA showed that choroidal background fluorescence and central artery were perfused slowly,the vascular fluorescence perfusion was interrupted before it came out of optic disk and the perfusion interruption continued until late stage with extensive peripheral non-perfusion areas.Conclusion The perfusion time of the retinal artery and vein in iatrogenic reti- nal vascular occlusion may be much longer than that in non-iatrogenic retinal vascular occlusion.
