背景:目前临床上应用激光针灸治疗膝骨关节炎的研究主要集中在改善疼痛及关节功能方面,对患者生活质量的情况鲜有报道或仅作为次要观察指标进行描述。 目的:观察二氧化碳激光灸对膝骨关节炎患者生活质量的影响。 方法:将31例膝骨关节炎患者随机分为治疗组和对照组分别接受为期4周,每周3次,每次20 min的二氧化碳激光照射犊鼻穴治疗和假治疗。 结果与结论:治疗组身体功能在治疗4周和随访时得分均明显优于治疗前(P=0.031,P=0.006);治疗组身体疼痛和健康感受在随访时得分均明显优于治疗前(P=0.007,P=0.011)。治疗组在治疗2周时身体功能和身体功能对角色的限制得分明显优于对照组(P=0.033);治疗组在随访时身体功能得分亦优于对照组(P=0.021)。治疗组身体疼痛得分改善趋势明显优于对照组(P =0.037)。提示CO2激光灸对膝骨关节炎患者在身体功能和身体疼痛方面的生活质量改善明显优于对照组。  相似文献

BACKGROUND: With an increasing life expectancy, there is a rapidly growing sector that is aging. Depression is the most prevalent functional mental disorder of older population. It is estimated that about 21% of the older population in Shanghai are suffering from depression. AIM: This study investigated the self-rated health related quality of life of community-dwelling older people diagnosed with depression in Shanghai, and to examine the relationships between this and mental and physical health, functional status and social support. METHODS: A cross-sectional survey was conducted in two community centres with a convenience sample of 71 participants. Measures included subjective perception of health related quality of life, level of depression, cognitive function, number of medical conditions, activities of daily living, functional abilities, and social support. The majority of the participants were female (n=52, 73.23%), and married (n=51, 71.8%). RESULTS: A higher level of depression was related to a poorer health related quality of life. Participants were least satisfied with their physical health. The level of depression, activities of daily living and satisfaction with social support were predictors of health related quality of life ratings. CONCLUSION: The study identified how depression affects the bio-psychosocial status of Chinese older people. Findings are discussed in light of the socio-cultural environment in Shanghai.  相似文献

Field potentials evoked by mid-cervical vagal stimulation were systematically mapped in the dorsal motor and solitary nuclei of the pigeon. Since responses varied predictably with microelectrode position, they could be used for localization in the dorsal medulla. By varying stimulus intensity and monitoring the vagal compound action potential, contributions of the different compound action potential waves were then established. Activation of the Bl-wave, which includes cardioinhibitory fiber activity, has its most prominent effect in the intermediate rostrocaudal zone of the dorsal motor nucleus in the region of subnuxleus b. This is where the cells of origin of the vagal cardiac fibers have previously been anatomically localized. Single unit experiments then established that (a) vagal motoneurons with axonal conduction velocities in the cardioinhibitory fiber range (8.0-14.5 m/sec) are primarily localized to the intermediate rostrocaudal zone of the dorsal motor nucleus in the region of subnucleus b, and (b) motoneurons in this zone that conduct at 8.0-14.5 m/sec distribute their axons in the cardiac branches. Furthermore, no error is introduced by identifying such neurons with mid-cervical rather than midthoracic vagal stimulation. Thus, the following criteria establish a neuron as giving rise to a vagal cardioinhibitory fiber: (a) localizing it to the intermediate rostrocaudal zone of the dorsal motor nucleus on the basis of the field potential evoked by mid-cervical vagal stimulation; (b) antidromically activating it with mid-cervical vagal stimulation; and (c) demonstrating that its axon conducts at 8.8-14.5 m/sec.  相似文献

The compound action potential components and their associated fiber contingents were investigated in the pigeon vagus nerve with a view toward identifying the vagal cardioinhibitory fibers. In the cervical vagus, the compound action potential evoked by electrical stimulation included four major components that conducted at 17.0-30.0 (A-wave), 8.0-14.5 (B2-wave) and 0.8-2.0 (C-wave) m/sec. Cardiac slowing was not elicited until activation of the Bl-wave, and the bradycardic response was maximal when this component was maximized. Electron microscopic analysis of the cervical vagus revealed myelinated fibers 1.1-6.8 micron in diameter and unmyelinated fibers 0.3-1.4 micron in diameter. A contingent of myelinated fibers approximately 2-4 micron in diameter apparently generated the Bl-wave, while the prominent unmyelinated fiber contingent (37%) accounted for the C-wave. Analysis of various vagal branches indicated that approximatley 20% of the cervical vagal fibers exit the main trunk between cervical and mid-thoracic levels, but few of these are the larger myelinated fibers greater than 2 micron in diameter. The upper abdominal vagus consists largely of unmyelinated and small myelinated fibers, and consequently the vast majority of larger myelinated fibers found in the cervical vagus exit between mid-thoracic and upper abdominal levels, presumably in the cardiac branches. Direct examination of the cardiac branches confirmed this. Thus, it is concluded that the Bl-wave of the compound action potential is uniquely associated with cardiac slowing, that this component is generated by myelinated fibers ranging from 2 to 4 micron in diameter, and that almost all such fibers are destined for the cardiac branches of the vagus.  相似文献

A 60-year-old woman afflicted with spontaneous CSF rhinorrhea was found to have a heterotopia consisting of well-differentiated neurons organized in layers in the lamina propria of the mucosa of the ethmoid sinus. This heterotopic cerebral anlage is best classified within the spectrum of “nasal gliomas”. The origin of this malformation is a failure of closure of the anterior neuropore which delays the ingrowth of the mesoderm that is destined to form the skull and dura beyond the 10th week of gestation, leaving behind trapped cerebral tissue. The presentation of this congenital malformation late in life is attributed to the development of sinusitis.  相似文献

Responses of pigeon retinotectal afferents to changes in whole field illumination are quantitatively analyzed for 313 units recorded in the stratum opticum. One hundred per cent of these units were responsive in unanesthetized birds and 92.9 percent in urethane anesthetized preparations. Of the responsive units, 92.4 percent (anesthetized) and 100 percent (unanesthetized) gave on-responses whose discharge characteristics showed an orderly relationship to stimulus intensity. Following the on-response, discharge generally ceased during sustained illumination. At stimulus termination off-responses frequently occurred, their probability being a function of stimulus intensity and duration. This probability, as well as specific response characteristics, could be predicted to a large extent from on-response characteristics. Anesthesia and level of background illumination predictably affected these response characteristics quantitatively but did not alter them qualitatively. It is hypothesized that with respect to whole field illumination the pigeon's retinotectal afferents constitute a homogeneous population continuously distributed according to threshold for intensity change.  相似文献
