ABSTRACT
Objective To investigate the effects of three-dimensional titanium mesh repair on cerebral perfusion,intracranial pressure and nerve function after decompression with bone flap.Methods From October 2015 to October 2018,132 hypertensive cerebral hemorrhage patients of bone disc decompression in the Fifth People's Hospital of Jinan were selected and divided into observation group (66 cases) and control group(66 cases) by double blind random method.The observation group received three-dimensional titanium mesh repair at 24 ～ 42 d after bone disc decompression surgery.The control group received three-dimensional titanium mesh repair at 90 ～ 150 d(3 ～ 5 months) after surgery.The changes of operation,cerebral perfusion,intracranial pressure and nerve function were compared between the two groups.Results The operative time,blood loss and free time of the flap in the observation group were (92.5 ± 12.4) min,(354.3 ± 17.5) mL and (13.2 ± 3.1) min,respectively,which were shorter or less than those in the control group [(142.8 ± 15.3) min,(518.3 ± 22.3) mL and (38.3 ± 4.3) min],the differences between the two groups were statistically significant (t=4.745,6.831,4.963,all P ＜ 0.05).After treatment,the abnormal indices of intracranial pressure and cerebral perfusion in the observation group were (0.1 ±0.0) and(0.2 ± 0.1),respectively,which were lower than those in the control group [(0.2 ± 0.1),(0.3 ± 0.1)] (t =3.657,2.579,all P ＜0.05).There were statistically significant differences in neurological deficit scores between the two groups at different time points(all P ＜0.05).The incidence of treatment complications in the observation group was 10.94％ (7/64),which was significantly lower than that in the control group [38.7％ (24/62)] (x2 =14.094,P ＜ 0.05).Conclusion Three-dimensional titanium mesh repair is helpful to shorten the operation time,restore the intracranial pressure on the affected side,improve the abnormal cerebral perfusion,and reduce the neurological damage in patients with hypertensive cerebral hemorrhage.
ABSTRACT
The disrupted caregiver infant relationships are not unpopular (infant abuse and non-traumatic caregiver-infant relationship).Animal and human studies have demonstrated this disruptive relationship exerts the fundamental and enduring impacts on stress system, limbic system and relevant cortex.Individual carrying such biological susceptibility might develop psychopathology under stresses at later life.The assessment needs to get involved the measures with more objectivity,real time and moment-to-moment components.The study on caregiverinfant relationship also should focus on the historical and cultural aspects of China.
ABSTRACT
Objective:To investigate the migration and odontogenesis of rat dental pulp cells transfected with adenovirus vector enco-ding cadherin-11.Methods:The dental pulp cells were cultured and transfected with pDC316-mCMV-EGFP-Cadherin-11.Cad-11 protein expression of the cells was examined by immunohistochemistry staining.The odontogenic differentiation of the cells was studied by alizarin red staining and ALP staining.The adhesion and migration of the cells were tested.Results:Transfection of pDC316-mC-MV-EGFP-Cadherin11 promoted Cad-11 protein expression and ALP activity,increased calcified nodule formation(P <0.05),adhe-sion and migration of rat dental pulp cells(P <0.05).Conclusion:Cadherin-11 may promote the odontoblast differentiation and mi-gration of rat dental pulp cells.
ABSTRACT
ObjectiveTo explore the clinic symptom and the characteristics of video,tightly close,intracranial electroencephalogram (EEG) of patients with central region diastematia epilepsy. Methods Retrospective analysis of 9 patients with central region diastematia epilepsy admitted from June,2007 to August,2009.The characteristics of all patients' seizure symptom and EEG manifestation were analyzed using patients' medical history,video and EEG records.ResultsPatients with central region diastematia epilepsy had relatively long sezure history.The duration of seizure was commonly short,with frequent episode and no obvious intelligence impairment.The seizure was often accompanied with the hyperkinesia in the lower limbs.Scalp EEG showed discharges with low amplitude waves in the mean line area.The superhigh amplitude and regular rhythm slow sharp wave could be found in the diastematia cortex EEG.All patients had an Engel Class Ⅰ outcome after surgery.ConclusionThe seizure symptoms are characteristic in the patients with central region diastematia epilepsy,and some special manifestations can be found in different phase,wave amplitude,rhythm,lead array.
ABSTRACT
@#Objective To explore the characteristic of intelligence, personality and mentality of patients with intractable epilepsy and analyzethe related factors on intelligence. Methods 68 patients with intractable epilepsy and 60 healthy persons were assessed with Raven'sstandard progressive matrices (SPM), Eysenck personality questionnaire (EPQ) and 90 symptoms checklist (SCL-90). The related factors onintelligence were analyzed. Results Compared with controls, the total score and IQ of SPM of the patients decreased significantly (P<0.05).There were 51.4% of intellectual deficiency in patients with intractable epilepsy, which was higher than that of controls (1.7%) (P<0.05).There was no significant difference in score of EPQ and the proportion of personality type between 2 groups (P>0.05). The total score ofSCL-90 and the factor score, such as somatization, interpersonal sensitivity, depression, anxiety and hostility in patients were higher thanthose in controls(P<0.05). Various factors, including the onset age, course of disease, seizure types, frequency, duration, number of drug, thescores of SCL-90 were correlated with the intelligence of epileptic patients (P<0.05). Conclusion The intelligence of many patients with intractableepilepsy were damaged, and many patients were with various psychological barriers. The onset age, course of disease, seizuretypes, frequency, duration and number of drug were important factors related with intellectual disorders in patients with intractable epilepsy.
ABSTRACT
Objective To assess the value of magnetic source imaging (MSI) in localizing the linguistic center of auditory function of epileptic patients before operation. Methods Epileptic focus and the linguistic center of auditory function in 24 patients were localized with MSI before operation. And the relationship between epileptic focus and auditory language area was observed. Results The linguistic center of auditory function was localized in left temporal lobe in 14 patients, in right temporal lobe in 5 patients and in bilaterial temporal lobe in 5 patients. Epileptic focus was localized in left temporal lobe in 14 patients, in left temporal lobe and left parietal lobe in 1 patient, in right temporal lobe in 4 patients, in right temporal lobe and parietal lobe in 1 patient, in left frontal lobe and left temporal lobe in 1 patient, in right frontal lobe, right temporal lobe and parietal lobe in 1 patient, and in bilaterial temporal lobe in 2 patients. Epileptic focus was superimposed with the linguistic center of auditory function in 10 patients, while was not superimposed with the linguistic center of auditory function in 10 patients. The epileptic focus was localized in front of the linguistic center of auditory function in 3 patients, in behind of the linguistic center of auditory function in 1 patient. The lesion of the patient suffered from dysembryoplastic neuroepithelial tumor was not excised completely because the epileptic focus was superimposed with the linguistic center of auditory function, and the patient appeared language functional disturbance after operation in short period, remaining auditory hallucination occasionally after operation. Conclusion Epileptic focus and the linguistic center of auditory function can be localized accurately and the relationship between them can be observed clearly with MSI. MSI is useful to reduce the occurrence of language disturbance after operation.
