ABSTRACT
Severe acute pancreatitis is sometimes complicated by a syndrome of cerebral dysfunction, referred to as pancreatic encephalopathy. Demyelination is found in autopsy and considered as basic pathologic evidence in patients with pancreatic encephalopathy. Myelin basic protein detection in cerebrospinal fluid and blood, combined with magnetic resonance imaging scan might indicate the demyelinatic change. Further large-scale study on both pathogenesis and diagnosis of this disease is needed.
ABSTRACT
Objective: To observe the effects of needling Baihui (GV 20), Shuigou (GV 26) and Shenmen (HT 7) on cerebral glucose metabolism in patients with vascular dementia (VD) by cerebral functional imaging technique. Methods: Twenty-five patients with VD were divided into 5 groups (Group A, B, C, D and E) randomly. Patients in the Group A were treated by needling routine acupoints for hemiplegia (Acupoints of the three yang meridians of hand and foot), and besides the routine acupoints, patients in the Group B were treated by needling Baihui(GV 20), the Group C by Shuigou(GV 26), the Group D by Shenmen(HT 7), and the Group E by Baihui(GV 20), Shuigou(GV 26), and Shenmen(HT 7). All the patients were examined by Positron Emission Tomography (PET) to detect the cerebral glucose metabolism in the bilateral frontal lobes(orbital gyri), parietal lobes, temporal lobes(hippocampus and hippocampal gyrus), occipital lobes, thalamus, lentiform nucleus, caudate nuclei, cingulate gyms and cerebellum before treatments and after treatments. Results: After needling the routine acupoints for hemiplegia, glucose metabolism increased in lentiform nucleus and temporal lobe;needling Baihui(GV 20), increased in frontal lobe, temporal lobe and lentiform nucleus;needling Shuigou(GV 26), increased in frontal lobe, thalamus and lentiform nucleus; needling Shenmen(HT 7), increased in parietal lobe and lentiform nucleus; and needling these three acupoints, increased in frontal lobe, temporal lobe, thalamus and lentiform nucleus. Conclusion:Needling Baihui(GV 20), Shuigou(GV 26) and Shenmen(HT 7) affect glucose metabolism in different functional regions of the brain, and Baihui(GV 20), Shuigou(GV26) and Shenmen(HT 7) relate to different functional regions of the brain.
ABSTRACT
[Objective]To observe the cerebral activating effects of needling in Yanglingquan(GB34) vs a sham point of healthy volunteers based on the technique of fMRI.[Methods]Sixteen healthy volunteers were randomly divided into GB34 group and sham point group,and received needling in the different points on the right side respectfully.Super nuclear magnetic resonance(1.5T,GE Co.) was used to scan the brain and the obtained experimental data of the regional brain were processed and analyzed by method of Region of Interest(ROI).[Results]There was not any difference between needling in GB34 and the sham point in the cerebral activating rate.While the activating number of needling in the sham point was more than that of needling in GB34 in bilateral parietal lobes and right occipital lobe(P
ABSTRACT
In this study, cerebral functional laterality patterns of medical students in the year 2005 were compared with those in the year 1995. Questionnaires on the behavior patterns were asked, and the laterality patterns were classified as right hemispheric (R)-balanced hemispheric (B)-left hemispheric (L). 385 students were studied (210 male and 175 female). Of the 3 categories, male students showed the patterns of R (42.8%), B (31.9%) and L (25.3%). Female students showed R (45.2%), B (30.9%) and L (23.9%). As the above result shows, laterality patterns of male and female were similar. The above data were compared with the another data in the article reported in 1995. Previous report showed that R (63.5%), B (24.9%) and L (11.6%) in the male students, and R (49.0%), B (22.4%) and L (28.6%) in female students, respectively. From the above results, It was suggested that cerebral laterality patterns of medical students in the year 2005 shifted toward left, but it still remained 42~45% in right hemispheric as contrast to 24~25% in left hemispheric. Hemispheric shift was interpreted as that, it may be the result of student's adaptative or competitive activities in the fast changing social environment.

To mitigate penumbra injury is the key factor in the treatment ofischemic stroke.Blood reflow and neuroprotection against time are premise to achieve this.Due to time window, thrombolysis rate is low(less than 5% in developed country).However, all neuroprotectants haven't been demonstrated to be effective in human, till now.Based on guidance ofwholism concept ofTCM and analysis ofrelative studies in western medicine.We found that functional status ofnon-ischemic areas can impact on injury degree offocal ischemia.One ofthe reasons that lead to failure in neuroprotective studies may be without considering this impaction.We put forward that non-ischemic areas can impact on the injury degree ofischemic area through the complex neuronal network, and effective regulating the functional status ofnon-ischemic areas is one ofthe key factors which can ameliorate focal ischemic injury.
