Objective To explore the number variation trend of inpatients with traumatic brain injury (TBI) in high altitude and plain areas. Methods The first page information in medical records of TBI patients, who were admitted to military hospitals from 2001 to 2007, was searched and extracted from the Chinese Trauma Database. Two military hospitals in high altitude area and another two in the same hospital level in plain area were selected. Then, the number variation trend of TBI inpatients in those two areas was compared. Results In high altitude area, the proportion of male patients and their median inpatient days were higher, while the age, proportion of Han patients and surgery rate were lower than those in plain area (all Plt;0.001). During 2001-2007, there were 9 141 TBI patients discharged from the four hospitals, and the average annual growth rate was 13.15%. In high altitude area, the average annual growth rate of discharged inpatients was 24.00%, while in plain area, it was just 7.09%. The 4 common categories of TBI were intracranial injury, open wound of the head, neck and trunk, skull fracture, and other injuries. Conclusion Compared with the plain area, there are significant differences in the demographics, hospital stay and surgery of inpatients in high altitude area. The average annual growth rate of TBI inpatients discharged from hospitals in high altitude area is faster than that in plain area, to which should be paid attention by relevant departments.
Objective To review the possible mechanisms of the mammal ian target of rapamycin (mTOR) in theneuronal restoration process after nervous system injury. Methods The related l iterature on mTOR in the restoration ofnervous system injury was extensively reviewed and comprehensively analyzed. Results mTOR can integrate signals fromextracellular stress and then plays a critical role in the regulation of various cell biological processes, thus contributes to therestoration of nervous system injury. Conclusion Regulating the activity of mTOR signaling pathway in different aspects cancontribute to the restoration of nervous system injury via different mechanisms, especially in the stress-induced brain injury.mTOR may be a potential target for neuronal restoration mechanism after nervous system injury.
Mild traumatic brain injury has a large number of patients in China. In recent years, studies have pointed out that the return to work is a key goal for rehabilitation, indicating that patients can start integrating into society again and resume normal work and life as soon as possible, which has a positive impact on their rehabilitation. This article summarizes the relevant factors that affect the return to work from four aspects: individual, disease, occupation, and social support, and introduces intervention measures such as follow-up and health education, neuromodulatory technology, symptom management, social support, cognitive and occupational rehabilitation, and multidisciplinary occupational rehabilitation, aiming to provide a reference for promoting the research and development of patients with mild traumatic brain injury returning to work in China.
Objectives To assess the efficacy and safety of standard trauma craniectomy (STC), compared with limited craniectomy (LC) for severe traumatic brain injury (sTBI) with refractory intracranial hypertension. Methods We searched the Cochrane Central Register of Controlled Trials-Central (The Cochrane Library Issue 3, 2008), MEDLINE (1966 to October 2008), EMbase (1984 to October 2008), CMB-disc (1979 to October 2006) and CNKI (1979 to October 2008) for completed studies, as well as clinical trial registries for ongoing studies and completed studies with unpublished data. The reference of included studies and relevant supplement or conference abstracts were handsearched. The search results were extracted, and then the quality of included studies was assessed using RevMan 5.0. Meta-analysis was conducted if the data was similar enough. Results Two randomized controlled trials (RCTs) involving 716 participants were identified. Compared with the LC group, the STC group had statistically significant, more favorable outcome on the basis of the Glasgow Outcome Scale, using measures such as mortality, efficiency, and survival, compared with those of LC group, which had statistic difference. The mean ICP fell more rapidly and to a lower level in the STC group than in the LC group. There was no statistically significant difference on the incidence of postoperative complications, including delayed hematoma, incision cerebrospinal fluid fistula, encephalomyelocele, traumatic epilepsy, and intracranial infection as well. Conclusion The efficacy of STC is superior to LC for severe TBI with refractory intracranial hypertension resulting from unilateral frontotemporoparietal contusion with or without intracerebral or subdural hematoma.
Objective To collect the clinical data of victims with traumatic brain injury (TBI) admitted in the West China Hospital of Sichuan University within 2 weeks after 4.20 Lushan earthquake, and to analyze their clinical characteristics and effects of early rehabilitation, so as to provide baseline data for rescue TBI victims with the early rehabilitation treatment during emergency medical rescue. Methods A total of 392 victims admitted in the hospital from April 20th, 2013 to May 3rd, 2013 were screened, of which the TBI victims were clinically assessed and treated with early rehabilitation. Then both the activities of daily living (ADL) and the Rancho Los Amigos Cognitive Recovery Scale (RLA) before and after the treatment were analyzed. The data were input by Excel software, and the statistical analysis was performed by SPSS softwar. Results A total of 51 TBI victims at age from 3 to 84 years old were included finally. The categories of TBI included subarachnoid hemorrhage (41.2%), intracranial hematoma (33.3%) and mixed type (33.3%), and the severity were associated with the type of TBI. The GCS score of cerebral concussion was higher (13.25 ± 0.62) while that of the diffuse axonal injury was lower (4.50 ± 0.71). All victims (100%) had limited ADL, 74.51% had cognitive dysfunction, 9.80% had speech disorder, and 7.84% had dysphagia. After the early rehabilitation treatment, both ADL (before treatment: 34.82 ± 58.29, after treatment: 69.63 ± 22.29) and RLA (pre-treatment: 4.16 ± 1.24, treatment: 7.20 ± 1.69) were obviously higher than those before treatment, with statistical differences (both P lt;0.05). Conclusion The TBI categories of Lushan earthquake victims are various and mixed, and the severity associated with the type of TBI. All TBI victims are accompanied with more clinical problems and functional limitation. Early rehabilitation treatment is safe and effective to improve ADL and RLA as well.
ObjectiveTo investigate the effects of large trauma craniotomy on severe traumatic brain injury. MethodsA total of 132 cases of severe traumatic brain injury adopted large trauma craniotomy between July 2008 and August 2013, and the clinical data were retrospectively analyzed. ResultsAccording to the results of GOS assessment at discharge, 67 patients (50.75%) were satisfied, 26 (19.70%) were mildly disable, 10 (7.58%) were severely disable, 12 (9.09%) were in vegetative state, and 17 (12.88%) were dead. ConclusionCorrect use of large trauma craniotomy on severe brain injury cases will help to improve the treatment outcome, reduce complications and improve quality of survival.
In recent years, although the mortality rate caused by traumatic brain injury has declined, the disability rate has remained high, which has a serious impact on patients and their families. Therefore, solving the complications and sequelae caused by traumatic brain injury is the focus and difficulty of current clinical research. Integration of traditional and western medicine rehabilitation is an effective method for the treatment of the central nervous system at home and abroad, and it also fully reflects its therapeutic advantages in the application of traumatic brain injury. Based on this, this paper will mainly introduce the clinical characteristics of patients with traumatic brain injury, and systematically expound the commonly used clinical rehabilitation treatment methods of integration of traditional and western medicine, aiming to provide a certain guidance for the rehabilitation treatment of traumatic brain injury.
ObjectiveTo investigate the clinical feature, prognosis and prognostic factors of early post-traumatic seizures in children. MethodsRetrospective review was performed on 101 individuals with early post-traumatic seizures (EPTS) who were diagnosed in Department of Neurosurgery in Children's Hospital of Chongqing Medical University from January 2008 to June 2013. The record was collected, which included patient's demographics, clinical and radiological presentation, management, and follow-up results of 12 months. The individuals were divided into late post-traumatic seizures (LPTS) group and control group according to the occurrence of LPTS or not. The SAS 9.2 was used for statistical analysis. ResultsDuring 101 cases in our study, male accounted for 60.4%, female accounted for 39.6%, and the ratio was 1.5 to 1. The percentage of patients who were under 6 years old was 74.3%, and the number of cases decreased with age. The peak time of EPTS was within 24 hours after traumatic brain injury. 55.4% of EPTS was the generalized seizures, 34.7% was the partial seizures, and 9.9% was the partial seizures and evolved to secondarily generalized seizures. The incidence of LPTS observed in our study was 26.7% within 12 months follow-up. The electroencephalogram displayed epileptiform discharges in 3 individuals who were without epileptic seizures. There was statistically significant difference in group LPTS compared to control group on these factors which included GSC score≤8(P=0.0064), complicated necrencephalus and/or encephalatrophy(P < 0.0001), multiple brain injuries(P=0.0210), subdural hemorrhage(P=0.0151) and intracranial operation(P=0.0029). The age, history, epileptic seizure type of EPTS, brain contusion, skull fracture and the early use of antiepileptic drugs (AEDs) had no statistically significant difference between LPTS group and control group(P > 0.05). ConclusionsEPTS is prone to occur in children under 6 years old. Male is obviously more than female, and the ratio is 1.5:1. The peak time of EPTS is within 24 hours after traumatic brain injury and most of EPTS are generalized seizures. The incidence of LPTS in children with EPTS exceeds those previously reported. Periodical electroencephalogram examination is essential to decrease the missed diagnosis of LPTS. The GSC score≤8 and complicated necrencephalus and/or encephalatrophy will dramaticlly increase the risk of LPTS. Multiple brain injuries, subdural hemorrhage and intracranial operation are also risk factors for the prognosis of EPTS. Although the use of AEDs is unable to decrease the incidence of LPTS after 12 months follow-up, it is probably beneficial to improving the cognition and brain development. The controversial finding in our study is whether intracranial operation can influence the prognosis of EPTS or not.
Patients with severe traumatic brain injury (TBI) have a higher mortality rate, often dying within a few hours after injury. The management of trauma site, transportation, and early hospital stay is closely related to the outcome of TBI patients. The final success rate of TBI patients varies after different prehospital treatments, and the quality of prehospital treatment for TBI needs to be further improved. Therefore, the TBI prehospital management guideline emerged, and the third version of the guideline was released in April 2023. In order to provide better advice and guidance on the treatment of prehospital TBI, this article interprets the key points of updating the third edition of the prehospital TBI management guideline.
Correlation between nonlinear subharmonic scattering of ultrasound contrast agent microbubbles and ambient pressure is expected to be used for local brain tissue pressure monitoring. Although high-frequency ultrasound has achieved high-resolution imaging of intracranial microvessels, the research on high-frequency subharmonic scattering characteristics of microbubbles is insufficient at present, which restricts the research progress of estimating local brain tissue pressure based on high-frequency subharmonic scattering of microbubbles. Therefore, under the excitation of 10 MHz high-frequency ultrasound, the effects of different acoustic pressures and ambient pressures on the high-frequency subharmonic scattering characteristics of three different ultrasound contrast agents including SonoVue, Sonazoid and Huashengxian were investigated in this in vitro study. Results showed that the subharmonic scattering amplitudes of the three microbubbles increased with the increase of ambient pressure at the peak negative acoustic pressures of 696, 766 and 817 kPa, and there was a favorable linear correlation between subharmonic amplitude and ambient pressure. Under the above three acoustic pressures, the highest correlation coefficient of SonoVue was 0.948 (P = 0.03), the highest sensitivity of pressure measurement was 0.248 dB/mm Hg and the minimum root mean square error (RMSE) was 2.64 mm Hg. Sonazoid's highest correlation coefficient was 0.982 (P < 0.01), the highest sensitivity of pressure measurement was 0.052 dB/mm Hg and the minimum RMSE was 1.51 mm Hg. The highest correlation coefficient of Huashengxian was 0.969 (P = 0.02), the highest sensitivity of pressure measurement was 0.098 dB/mm Hg and the minimum RMSE was 2.00 mm Hg. The above in vitro experimental results indicate that by selecting ultrasound contrast agent microbubbles and optimizing acoustic pressure, the correlation between high-frequency subharmonic scattering of microbubbles and ambient pressure can be improved, the sensitivity of pressure measurement can be upgraded, and the measurement error can be reduced to meet the clinical demand for local brain tissue pressure measurement, which provided an important experimental basis for subsequent research in vivo.
