Summary: John Hughlings Jackson's theory of consciousness has been reconsidered. The author stressed that his uniqueness as a neuroscientist lay in his keen interest in the recursive nature of human consciousness. Two clinical symptoms of interest to Jackson were discussed: recurrent utterances and mental diplopia. Recurrent utterances were believed to represent an exceptional state, in which the unconscious process in speech production, otherwise destined to be swept away automatically, became manifest and observable. Jackson regarded mental diplopia as a revelation of otherwise inaccessible duality of all healthy mental actions. Therefore, he supposed that the essence of recursive consciousness resided in a transformation of multiple, multidirectional, unconscious processes into a linear, unidirectional process 相似文献

A 53-year-old female presented with an unruptured, large basilar trunk aneurysm manifesting only as headache with no neurological deficits, including absence of cranial nerve dysfunction. Cerebral angiography disclosed a large aneurysm with a wide neck arising from the midbasilar artery. We treated the aneurysm surgically via the posterior petrosal approach. Five angled clips were applied sequentially to the aneurysm and the basilar artery was successfully reconstructed. Electrophysiological monitoring was continued during the operation and showed no changes. Following the operation, the patient suffered from transient right abducens nerve palsy, which persisted for 3 months. Postoperative angiography showed that the aneurysm was obliterated, and the patency of the basilar artery was preserved. 相似文献

Non-N-methyl-D-aspartate glutamate receptors mediate oxygen--glucose deprivation-induced oligodendroglial injury 总被引:2,自引:0,他引:2

Cells of oligodendroglial lineage are susceptible to oxygen and glucose deprivation. When oligodendrocyte-like cells differentiated from CG-4-immortalized rat O-2A progenitor cells were exposed to hypoxia alone or glucose deprivation alone for 48 h, release of lactate dehydrogenase (LDH) into the culture medium did not increase. However, when cells were deprived of both oxygen and glucose for 6 or 12 h preceding reoxygenation for 2 h, LDH release increased. Adding glucose to the medium protected against cell death and increased lactate production in a concentration-dependent manner. Cell damage induced by deprivation of oxygen and glucose was prevented by calcium-free medium or by non-N-methyl-D-aspartate glutamate receptor (GluR) antagonists, such as 6-cyano-7-nitroquinoxaline-2,3-dione or LY293558, but not by the voltage-dependent calcium channel blocker, nimodipine, or by the N-methyl-D-aspartate GluR antagonist, MK-801. The glutamate concentration in the medium from cells exposed to oxygen-glucose deprivation for 12 h was 49.70+/-3.04 microM/l, which is sufficient to activate GluRs during deprivation of oxygen and glucose. Apoptotic cells detected by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-biotin nick end-labeling (TUNEL) or Hoechst 33258 staining did not increase in cells exposed to oxygen-glucose deprivation for 12 h and subsequent reoxygenation for 2 h. No DNA laddering was detected by agarose gel electrophoresis from cells exposed to deprivation of oxygen and glucose. Neither acetyl-YVAD-CHO, an inhibitor of caspase-1-like proteases, nor acetyl-DEVD-CHO, an inhibitor of caspase-3-like proteases, prevented oxygen-glucose deprivation-induced injury. Thus, oxygen and glucose deprivation causes calcium-influx-induced necrotic cell damage in cells of oligodendroglial lineage via non-N-methyl-D-aspartate GluR channels. 相似文献

Little is known about the participation rate of newly implemented colorectal cancer (CRC) screening programs in China. Our goals were to identify factors associated with nonparticipation for CRC screening in Songjiang District, Shanghai.We analyzed individuals included in an observational cohort study from 4 towns (Xin Qiao, She Shan, Mao Gang, and Zhong Shan) in Songjiang District. The participation rate was calculated for the CRC screening program based on a fecal immunochemical test and a risk assessment questionnaire between 2015 and 2017 inclusive.Of the 27,130 individuals eligible for inclusion in this study, 20,863 (76.9%) participated in CRC screening at least once during 2015 and 2017. The factors linked with nonparticipation were; being male (odds ratio [OR] 0.87, 95% confidence interval [CI] 0.82–0.93, P < .01), unmarried (OR 0.71, 95% CI 0.64–0.80, P < .01), having a high education level (middle school, OR 0.82, 95% CI 0.74–0.90, P < .01, high school or above, OR 0.64, 95% CI 0.57–0.73, P < .01), absence of chronic disease (OR 0.90, 95% CI 0.85–0.96, P < .01), and living in 2 out of the 4 towns covered (Xin Qiao, OR 0.72, 95% CI 0.66–0.78, P < .01, Zhong Shan, OR 0.29, 95% CI 0.26–0.31, P < .01).The current study revealed several associated factors with nonparticipation for the CRC screening in Songjiang district. These findings will help identify target populations that require an individualized approach to increase the participation rate. 相似文献

The case reported here showed a radiological appearance of hypoplasia of the right lung, dextroposition of the heart, and a curved vascular shadow in the right lower lung field known as a scimitar sign. However, a computed tomography of the chest showed this abnormal vascular shadow draining into the left atrium (pseudo-scimitar sign). Therefore, in patients with a radiological appearance of the scimitar syndrome, computed tomography of the chest should be indicated to rule out the pseudo-scimitar sign. 相似文献

Successful vasodilator therapy of a 19 year old woman with primary pulmonary hypertension is described. Long-term home oxygen therapy during sleep (2 1/min, 8 hours) in combination with vasodilator drugs (prazosin 2 mg and long-acting ISDN 20 mg bid) and an anticoagulant (ticlopidine 100 mg bid) brought significant reduction of pulmonary artery pressure and a rise of cardiac output 3 years later. This combination therapy may be effective in selected patients with primary pulmonary hypertension. 相似文献

Through the examination of 171 electrocardiograms (ECG) of 101 patients with primary pulmonary hypertension (PPH), the following conclusions were obtained. Arrhythmias were found in 27 (26.7%) of the 101 patients. Among the surviving cases, arrhythmias were found in 8 (17.8%) out of 45 patients, but among the decreased cases, the figure was higher, 19 (33.9%) out of 56. There were instances of more than one kind of arrhythmias in the same patient and a total of 34 types of arrhythmias were noted. The main types of arrhythmias were sinus tachycardia (13 cases), sinus bradycardia (6 cases), and first degree A-V block (5 cases), which accounted for 70% of the total. Sinus tachycardia was observed in only 2 of the survivors but in 11 of the decreased cases, which showed a significant difference (p less than 0.05). First A-V block were all induced by digitalis. Wenckebach type of second degree A-V block was noted in only 1 case and it was also induced by digitalis. Since severe attacks of ventricular arrhythmias were very rare in these cases with PPH, it is difficult to consider the Adams-Stokes syndrome as the cause of syncopal attacks or sudden death. However, it is necessary to further investigate nodal functions by means of continuous ECG monitoring, the overdrive suppression test and His bundle ECGs. 相似文献

Accessory mitral valve leaflet is a rare congenital anomaly. More than half of the cases show other congenital cardiac defects and almost all of the cases show subaortic obstruction. We report a case of an accessory mitral valve tissue without outflow obstruction associated with mitral cleft of the posterior mitral leaflet. To our knowledge, this is the first reported case of the combination of these two congenital anomalies. 相似文献

We reviewed 649 primary lung cancer patients with special reference to the occurrence of thromboembolism. Thirteen episodes of thromboembolism were detected in 12 (1.8%) of the 649. Eight of the 12 were men, and their mean age was 63. Adenocarcinoma was the predominant cell type. Most patients had an advanced stage of the disease, but in some in the cancer was at an early stage. In 5 cases, the finding of thromboembolisms led to diagnosis of the lung cancer (38.5%). Anticoagulant therapy was performed in 9 cases, of which 8 responded without serious complication. We emphasize the importance of anticoagulant therapy as a therapy indicated for thromboembolism in patients with lung cancer. 相似文献
