ABSTRACT
Objective To explore the effects of extension nursing on quality of life in cervical cancer patients after radiotherapy. Methods A total of 80 hospitalization patients from January 2013 to January 2015 was selected to join the QQL-BREF test. These 80 patients were divided into the experimental group and the control group, who all accepted regular health education, and the experimental group also accepted nursing once a month after discharge. The quality of life of patients in the two groups were assessed one year later. Results For the domain of physiological field, psychological field, independence, social, environmental, faith, the experimental group scored 3.73 ± 0.33, 3.66 ± 0.44, 3.67 ± 0.05, 3.48 ± 0.59, 3.73 ± 0.58, while the control group scored 1.68 ± 0.40, 2.39 ± 0.43, 1.76 ± 0.39, 2.10 ± 0.51, 3.02 ± 0.45 (t=1.26-21.15, P 0.05), Other 17 elements showed statistical difference (t=2.45-17.31, P < 0.01). Conclusions Extension nursing can improve cervical cancer patients′quality of life efficiently after radiotherapy and reduce the recurrence rate.
ABSTRACT
Objective To observe the expression of glial fibrillary acidic protein ( GFAP), and the pathological and ultrastructnral changes of astrocytes in the CA1 subfield of the hippocampus following global cerebral ischemia and reperfusion, and to explore the neuroprotective mechanism of mild hypothermia. Methods Global cerebral ischemia was established in rats by a modified version of Pulsinelli's method. Ninety-six rats were divided into three groups including a sham-operated group, a normothermic ischemic reperfusion (IR) group and a hypothermic ischemic reperfusion (HIR) group. Each group had four subgroups which were sacrificed for 6, 12 or 24 hours, or 4 days after reperfusion (for each subgroup n = 8 ). Hematoxylin-eosin (HE) staining was used to observe morphological changes in neurons in the CA1 subfield of the hippocampus. TUNEL methods were used to detect apoptosis among those neurons. Immunohistochemical staining was used to detect the expression of GFAP in the CA1 subfield and the mechanism of astrocyte pathology. GFAP TUNEL double-labeled immunohistochemistry was used with both the shamoperated and experimental groups. Electron microscopy was also used to evaluate morphological changes in astrocytes 24 hours and 4 days after ischemia and reperfusion. Results Compared with the sham-operated group, expression of GFAP immunoreactive positive cells increased gradually in the CA1 subfield of the IR group rats. Compared with the IR group, expression of GFAP immunoreactive positive cells was significantly lower in the HIR group at all time points. Microscopic observation at the 4th day showed that some astrocytes in the CA1 subfield had died through oncosis. Conclusions Mild hypothermia can significantly decrease the expression of GFAP immunoreactive positive cells and the number of apoptotic neurons in the CA1 subfield of the hippocampus, minimize cell oedema and provide protection for neurons. Oncosis kills astrocytes following global cerebral ischemia and reperfusion.
