Cerebrovascular dementia is a common disease in the middle-aged and old people. Its incidence makes up about 10-20% of all kinds of dementia. It is mainly caused by general degeneration of the brain function resulted from cerebral arteriosclerosis and cerebral infarction. The author has treated 32 cases of cerebrovascular dementia with acupuncture in the recent years with satisfactory therapeutic results. A report follows.

Here, we administered repeated-pulse transcranial magnetic stimulation to healthy people at the left Guangming (GB37) and a mock point, and calculated the sample entropy of electroencephalo-gram signals using nonlinear dynamics. Additionally, we compared electroencephalogram sample entropy of signals in response to visual stimulation before, during, and after repeated-pulse tran-scranial magnetic stimulation at the Guangming. Results showed that electroencephalogram sample entropy at left (F3) and right (FP2) frontal electrodes were significantly different depending on where the magnetic stimulation was administered. Additionally, compared with the mock point, electroencephalogram sample entropy was higher after stimulating the Guangming point. When visual stimulation at Guangming was given before repeated-pulse transcranial magnetic stimula-tion, signiifcant differences in sample entropy were found at ifve electrodes (C3, Cz, C4, P3, T8) in parietal cortex, the central gyrus, and the right temporal region compared with when it was given after repeated-pulse transcranial magnetic stimulation, indicating that repeated-pulse transcranial magnetic stimulation at Guangming can affect visual function. Analysis of electroencephalogram revealed that when visual stimulation preceded repeated pulse transcranial magnetic stimulation, sample entropy values were higher at the C3, C4, and P3 electrodes and lower at the Cz and T8 electrodes than visual stimulation followed preceded repeated pulse transcranial magnetic stimula-tion. The ifndings indicate that repeated-pulse transcranial magnetic stimulation at the Guangming evokes different patterns of electroencephalogram signals than repeated-pulse transcranial mag-netic stimulation at other nearby points on the body surface, and that repeated-pulse transcranial magnetic stimulation at the Guangming is associated with changes in the complexity of visually evoked electroencephalogram signals in parietal regions, central gyrus, and temporal regions.

事件相关电位对精神分裂症患者大脑认知功能的研究

Event related potentials(ERP) is an objective method for assessing brain function.It's components include P 50,N 200,P 300, mismatch negativity,processing negativity, late positive potentials. This paper reviews the new development of ERP research in patients with schizophrenia .

儿童大脑半球切除术后脑功能重建

INTRODUCTIONSince 1950, hemispherectomy was used widely for infantile hemiplegia with epilepsy. There are many new advances in the evaluation of hemispherectomy as the use of fMRI (functional magnetic resonance image), PET(positron emission tomograph), EP(evoked potential). Reorga-Nization of brain function were reviewd.

大量脑出血锥颅血肿清除术与运动功能康复

INTRODUCTION Mortality of profuse cerebral hemorrhage is high.Objective of therapy is to reduce injury of edema and recover brain function,improve successive rate of salvage,and decrease disability incidence.Puncture and removal of cerebral hematoma and drain with urokinase under CT dirction(0.3 cm of vertebral cerebral aperture) is safe and simple,impact of which on muscle fore and movement function is investaged in this study.

Hypoxia and the developing brain:factors underlying cell damage

Structural and functional integrity of brain function depends on a regular oxygen supply.

近红外光谱仪在小儿心外科脑功能监测中的应用

中枢神经系统损害是心脏外科术后影响小儿生活质量的主要并发症,临床上可有清醒延迟、昏迷、清醒后再昏迷、躁动、抽搐、偏瘫、失语、认知障碍、生理反射异常等各种表现以及目前尚检测不到的征象.

Orexins, hypothalamic neuropeptieds, are involved in modulation of food intake and arousal state. To examine further physiological roles of orexin in brain function, the effects of centrally administered orexin- A on body temperature was investigated in rats. Assessed by a telemetry-sensor system implanted into the abdominal cavity, infusion of orexin-A into the third cerebroventricle increased body temperature in a dose-responsive manner. Cumulative ambulatory activity was concomitantly increased during 6 h but not 12 h after administration of orexin-A. Expression of uncoupling protein 1 (UCP1) mRNA in brown adipose tissue, as a marker for peripheal thermogenesis which affects body temperature, failed to increase after orexin-A administration. Expression of UCP3 mRNA in skeletal muscle but not UCP 2 in white adipose tissue was upregulated by infusion of orexin-A. The resulting information indicates that orexin neuron regulates body temperature in coordination with control of arousal system independently of peripheral thermogenesis through the BAT UCP1.
