Chinese Journal of Rehabilitation Theory and Practice 2006;12(5):417-419
ObjectiveTo observe the manifestations of depression at different stages after cerebral concussion. Methods77 cerebral concussion patients received Hamilton Depression Rating Scale (HAMD) examination at acute stage (in the 7 days after disease) and convalescence stage (at about 30 days after disease), and then compared with 48 health adults. ResultsThe scores of anxietas somatization, cognitive handicap, retardation, dyssomnia, feeling of despair conclude the total score in the cerebral concussion patients at acute stage were all significantly higher than that of the control (P<0.05). During the convalescence stage, the scores of anxietas somatization, the change of body weight, cognitive handicap, diurnal variation, retardation, dyssomnia, feeling of despair conclude the total score were all significantly higher than that of the control (P<0.05). The scores of almost all the item of HAMD were significantly higher than that of the control at both acute stage and convalescence stage, and the scores of athymia, suicide, difficulty falling asleep, early awake, agitate, somatization, constitutional symptom, hypochondriasis, loss of weight, insight, diurnal variation, feeling of despair, anosognosia, sense of inferiority and total HAMD scores at convalescence stage were all significantly higher than that at the acute stage, but the scores of blockage, psychoanxietas, derealization, symptom of over-absorption mind, compel symptom, sense of capability decrease at the acute stage were all significantly higher than that at the convalescence stage (P<0.05).ConclusionThe manifestations of depression in the cerebral concussion patients were not completely the same, so the mental intervention should be in direction.

Objective To explore the significance and important measure of integrative treatment of multiple trauma patients with severe craniocerebral injury in emergency center. Methods One hundred and forty-eight multiple trauma patients with severe craniocerebral injury in emergency center from November 2002 to February 2006 were analysed retrospectively. Result In total 148 cases, 72 were cured and 26 dead, 7 were in status of plant man, 17 experienced severe deformity, and 26 did mild deformity. Conclusion Multiple trauma patients with severe craniocerebral injury usually experience a serious situation and rapid development. Therefore emergency doctors are required for organizing salvage of such patients, at the same time treatment and diagnosis are implemented. Firstly the most important key to successful salvage is appropriate disposal of fatal injury and early elimination of shock. Proper surgical choice, especially at the first time, inspection and protection of visceral functions, and attention to nutritional support are other vital methods to gain more successful salvage. ICU is also emphasized for its essentiality.

AIM: To evaluate the clinical outcomes of combined wavefront - guided and aspheric laser in situ keratomileusis ( LASIK ) to correct myopia and myopic astigmatism.
METHODS: Prospective study. Forty-five patients ( 62 eyes ) with myopia and myopic astigmatism were randomly dividied into two groups:the wavefront-guided and aspheric LASIK group and the wavefront- guided LASIK group. Safety, efficacy, predictability, ocular higher order aberrations(HOAs), and contrast sensitivity under mesopic condition were compared at 6mo postoperatively.
RESULTS: Both platforms had equal safety, efficacy and predictability. At 6mo after operation, total HOAs, spherical aberration and coma increased in both groups(P<0. 01 ). The changes of total HOAs and spherical aberration in wavefront-guided and aspheric group were significantly less than those in wavefront-guided group ( P<0.05 ) , while the change of coma between two groups was not statistically significant ( P = 0. 657 ). Contrast sensitivity in the wavefront-guided and aspheric group recovered to preoperative levels under mesopic conditions at all spatial frequencies ( P > 0. 05 ), while contrast sensitivity in the wavefront-guided group recovered to preoperative levels at all spatial frequencies(P>0. 05).
CONCLUSION: Wavefront-guided and aspheric LASIK induced less HOAs and associated with better mesopic contrast sensitivity compared with wavefront - guided LASIK.

Objective To summerize the clinical experience of 23 cases of carotid cavernous fistula(CCF) and discuss the treatment strategy. Methods Retrospectively analyzed 23 patients(11 males and 12 females) of CCF,including 14 patients with Barrow type A,1 with type B,1 with type C and 7 with type D. Results Vascular approach for embolization was undertaken in 20 cases by transarterial access and 2 via venous route while 1 case was given up. Among them,9 cases obtained complete occlusion by simple balloon embolization and 5 were treated by direct occlusion of internal carotid artery. Another 5 cases used NBCA glue for the occlusion,1 case was embolized by gelatin-sponge particulates combined with compression of carotid artery,2 cases were treated by coil embolization of cavernous sinus and 1 case was only managed by carotid compression maneuver. We achieved satisfactory clinical results with 21 patients cured and 2 patients improved. Conclusion Complexity and refractory are the characteristic of CCF,and endovascular treatment should be the major choice of treatment. (J Intervent Radiol,2006,15: 323-326)
