RESUMO

Aim: To observe the effects of acupuncture manipulations on blood pressure and brain function in spontaneously hypertensive rats and elucidate the anti-hypertensive effect of the manipulations' central mechanism. Methods: This study used acupuncture twirling reinforcing, acupuncture twirling reducing, and acupuncture twirling uniform reinforcing-reducing manipulations to act on the bilateral TaiChong point of rats. The depth of acupuncture was 1.5-2 mm, and twisting was performed at a frequency of 60 times/min within ±360° for 3 min, followed by the needle being retained for 17 min. Functional magnetic resonance imaging was performed at the end of the intervention. Regional homogeneity and amplitude of low-frequency fluctuations were used to assess the differences in brain regions in each group of rats, and the core brain region (left hypothalamus) among the differential brain regions was selected as the seed for functional connectivity analysis. Results: (1) The anti-hypertensive effect was achieved by acupuncture manipulations, and the anti-hypertensive effect of twirling reducing manipulation on spontaneously hypertensive rats was better than that of twirling uniform reinforcing-reducing and twirling reinforcing manipulations. (2) After regional homogeneity and amplitude of low-frequency fluctuations analyses, the hypothalamus, the brain region related to blood pressure, was activated in the twirling uniform reinforcing-reducing manipulation group; the corpus callosum and cerebellum were activated in the twirling reinforcing manipulation group; and the hypothalamus, olfactory bulb, corpus callosum, brainstem, globus pallidum, and striatum were activated in the twirling reducing manipulation group. (3) According to the functional connectivity analysis, different acupuncture manipulations increased the functional connections between seed points and the brainstem, olfactory bulb, and cerebellum, etc. Conclusion: These results suggest that acupuncture manipulations achieved the hypotensive effect and the twirling reducing manipulation had a better hypotensive effect on spontaneously hypertensive rats than twirling uniform reinforcing-reducing and twirling reinforcing manipulations; the central mechanism of the anti-hypertensive effect of twirling reinforcing and reducing manipulation may be related to the activation of brain regions associated with blood pressure regulation and the functional connections between them. Furthermore, brain regions involved in motor control, cognition, and hearing were also activated. We hypothesize that activation of these brain regions may help prevent or mitigate the onset and progression of hypertensive brain damage.

RESUMO

Introduction: Chronic hypertension may have a contributory role toward cognitive impairment. Acupuncture exerts protective effects on cognitive functions while controlling the blood pressure. However, the neural mechanism underlying the dual attenuating effect of acupuncture remains unclear. In this study, we investigated the effects of electroacupuncture (EA) and manual acupuncture (MA) on the functional activity of the brain regions of spontaneously hypertensive rats (SHRs) by through resting-state functional magnetic resonance imaging (rs-fMRI). We also evaluated the differences in these functional activities between the EA and MA groups. Methods: We randomly assigned 30 SHRs into the EA, MA, and model (SHR) groups. Wistar Kyoto rats (n = 10) were used as normal control (WKY). The interventions were administered once every alternate day for 12 weeks. The systolic blood pressure of all rats was recorded every 2 weeks until the end of the intervention. After the intervention, rs-fMRI scanning was performed to access the whole brain data of rats randomly selected from each group evenly. The amplitude of low frequency fluctuation (ALFF) analysis, regional homogeneity (ReHo) analysis, and functional connectivity (FC) analysis were also conducted. The Morris water maze (MWM) test was conducted to evaluate the learning and memory of the rats. Hematoxylin-eosin staining and Nissl staining were performed to observe histopathological changes in the key brain regions. Results: We demonstrated that, when compared with the SHR group, the EA and MA groups had significantly lower blood pressure and better performance for behavioral test indices, and that the effect of EA was better than that of MA. ALFF and ReHo analyses revealed enhancement of the neuronal activity of some functionally impaired brain areas in the EA and MA groups. The main callback brain regions included the hypothalamus, entorhinal cortex, brain stem, prelimbic cortex, cingulate cortex, corpus callosum, and cerebellum. The FC analysis demonstrated that EA and MA enhanced the functional connectivity between the seeds and brain regions such as the brain stem, entorhinal cortex, hippocampus, prelimbic cortex, and cerebellum. The pathological test of the entorhinal cortex also verified the protective effect of acupuncture on the neuronal functional activity. Discussion: Our findings suggested that EA and MA exhibited attenuating effects on hypertension and cognitive dysfunction by enhancing the functional activities in the corresponding brain regions. Moreover, EA activated more callback brain regions and functional connectivity than MA, which may explain why the effect of EA was better than that of MA.

RESUMO

Amyotrophic lateral sclerosis (ALS) is a progressive and lethal motor neurodegenerative disease. The cause of the disease is unknown, and there is no cure current clinical treatment methods include Riluzole and supportive therapy. However, Riluzole only decelerates the patient's muscle strength loss and prolongs survival by about 3-5 months (Aventis Pharmaceutical, 2004). The patient will die eventually because of aspiration pneumonia or respiratory failure. This paper documents the use of Orem's self-care theory and holistic nursing assessment in a patient with amyotrophic lateral sclerosis. There are four areas of nursing concern: impaired self-care ability (dressing, feeding, toileting, and bathing), risk of falls, impaired verbal communication, and powerlessness. In terms of these problems suitable nursing activities are provided to develop the patient's ability to care for himself, prevent accidents, promote skills of non-verbal communication, and alleviate powerlessness in order to strengthen control.

RESUMO

This case report describes the experience of taking care of an adolescent (nineteen year-old) girl, who needed spinal surgical treatment because of scoliosis. The author assessed the patient's condition by observation, interview, and the Gordon 11-item functional health pattern assessment guide. Because she had had no previous surgical experience, and faced changes in her bodily appearance, the adolescent had physical and psychological problems, such as acute pain, self-care deficit, anxiety, and body image disturbance. Besides applying professional knowledge and technical ability, to alleviate the discomfort caused by the young lady's surgery, the author used caring, listening and empathy to encourage and support her in learning self-care, to accept her change in body image, and to overcome the impact of the disease. Through this nursing process, the author came to understand that nurses must concern themselves with both physical problems and mental needs in order to provide holistic health care.

RESUMO

Preparatory sensory information (PSI) has been found to have significant effects in reducing distress, tension, restlessness, negative moods, and anxiety, and also in reducing length of postoperative hospitalization during various threatening medical events, but no evidence has demonstrated the effect of PSI on a patient during ICU hospitalization. On the basis of Lazarus' theory, a structural equation model was developed to examine the role of the nursing intervention, PSI, as a significant factor influencing patients' processes of cognitive appraisals and coping, adaptational responses, and patient care outcomes during ICU hospitalization. The analytical model examined the net effect of PSI on outcomes, controlling for the effects of mastery, interpersonal trust, social support, socioeconomic status, severity of illness, age, and gender. A quasi-experiment was executed in four large acute care hospitals. Data were collected from 41 subjects in the control group and from 42 in the treatment group receiving PSI before ICU admission. Structural equation modeling was employed to test the proposed analytic model. The initial tests of model fit indicate that the original model did not fit the data well with GFI = 0.85, AGFI = 0.76, RMSEA = 0.059, p_close = 0.28, and critical N = 78. A revised model was developed, and the fit indices suggested an adequate fit with GFI = 0.90, AGFI = 0.84, RMSEA = 0.00, p_close = 0.89, and critical N = 109. These findings provide empirical support for Lazarus' theory on stress, appraisal, and coping. The findings also verify the beneficial effects of the nursing intervention of PSI on ICU patients.
