Sports-related traumatic brain injury (srTBI) is a traumatic brain injury (TBI) caused by sports, which can result in cognitive and motor dysfunction. Currently, research on the molecular mechanism of srTBI and related drug development mainly relies on monolayer culture models and animal models. However, many differences exist in cell populations and inflammatory responses between these models and human pathophysiological processes. Most of the researches derived from the models can't effectively conducted translational research. Emerging three-dimensional (3D)

OBJECTIVE: To explore the effects of different mild hypothermia therapy time on the efficacy and complications of patients with severe traumatic brain injury (STBI). METHODS: A retrospective research method was used. 132 patients with STBI given mild hypothermia therapy admitted to the Third Affiliated Hospital of Gansu University of Traditional Chinese Medicine from January 2010 to December 2018 were enrolled. According to the days of mild hypothermia therapy, the patients were divided into 2-day mild hypothermia treatment group, 5-day mild hypothermia treatment group and 14-day mild hypothermia treatment group. Glasgow coma score (GCS) after treatment of 10 days and 30 days, 30-day disability rate and mortality, coma time, prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), D-dimer, and the incidence of complications such as decreased blood pressure, decreased gastrointestinal motility, infection, nonunion of scalp, cerebrospinal fluid leakage, etc. were compared among three groups. RESULTS: Among the 132 patients with STBI, there were 44 cases in the 2-day mild hypothermia treatment group, 45 cases in 5-day mild hypothermia treatment group, and 43 cases in 14-day mild hypothermia treatment group. There was no significant difference in gender, age, GCS score before treatment or time from injury to admission among three groups. Compared with 2-day mild hypothermia treatment group, the GCS score 10 days and 30 days after treatment in 5-day mild hypothermia treatment group and 14-day mild hypothermia treatment group were significantly higher (11.61±2.23, 10.17±2.03 vs. 6.79±1.49; 13.15±2.53, 11.24±2.24 vs. 8.79±1.59), the coma time were shorten (days: 5.79±1.89, 5.45±1.72 vs. 13.65±2.73), and 30-day disability rate and mortality were significantly decreased [13.33% (6/45), 11.63% (5/43) vs. 22.73% (10/44); 17.78% (8/45), 16.28% (7/43) vs. 31.82% (14/44)], PT and APTT were reduced obviously (s: 20.14±4.12, 22.54±3.56 vs. 30.67±5.19; 35.14±12.41, 38.59±13.54 vs. 56.67±10.62), Fib rose obviously (g/L: 1.84±0.25, 1.98±0.27 vs. 0.67±0.12), and D-dimer reduced obviously (mg/L: 53.10±19.84, 49.20±20.13 vs. 102.60±20.13), with statistically significant differences (all P < 0.05). But there was no significant difference in above indicators between the 5-day mild hypothermia treatment group and 14-day mild hypothermia treatment group (all P > 0.05). The incidence of complications in 14-day mild hypothermia group was significantly higher than those in 2-day mild hypothermia group and 5-day mild hypothermia group [decrease of blood pressure: 55.56% (20/36) vs. 36.67% (11/30), 35.14% (13/37); weakening of stomach intestinemotive power: 72.22% (26/36) vs. 46.67% (14/30), 45.95% (17/37); urethral infection: 52.78% (19/36) vs. 36.67% (11/30), 35.14% (13/37); lungs infection: 47.22% (17/36) vs. 36.67% (11/30), 37.84% (14/37); disunion of scalp: 5.56% (2/36) vs. 0% (0/30), 0% (0/37); leak of cerebrospinal fluid: 5.56% (2/36) vs. 0% (0/30), 0% (0/37), all P < 0.05], but there was no significant difference between the 2-day mild hypothermia treatment group and 5-day mild hypothermia treatment group (all P > 0.05). CONCLUSIONS The optimal time frame for mild hypothermia treatment in patients with STBI is 5-day, which shortens the coma time, and reduces the mortality and the disability rate. The shorter mild temperature time cannot effectively prevent secondary brain injury. However, the prolonged period of mild temperature will affect the repair of the patient's injury tissue, which is not conducive to the recovery of patient's mechanical function and is prone to complications.

OBJECTIVE: To explore the usability of regional saturation of cerebral oxygenation (rScO₂) combined with percentage of α variability (PAV) in predicting brain function prognosis in patients with traumatic brain injury (TBI). METHODS: A retrospective analysis was conducted. The clinical data of patients with TBI who were monitored rScO₂ and bedside quantitative electroencephalogram (qEEG) admitted to intensive care unit (ICU) of Henan Provincial People's Hospital from August 2018 to July 2019 were collected. The rScO₂, PAV, and Glasgow coma scale (GCS) score were recorded within 72 hours after the TBI. The primary prognostic indicator was the 3-month Glasgow outcome score (GOS) score. The differences between the two groups of poor prognosis of brain function (GOS score 1-3) and good prognosis (GOS score 4-5) were compared. Binary multivariate Logistic regression analysis was used to analyze the correlation between rScO₂, PAV, GCS score and the prognosis of brain function in patients with TBI. In addition, receiver operating characteristic (ROC) curve was plotted to analyze the predicting value of rScO₂ and PAV only or combination for prognosis of brain function. RESULTS: A total of 42 patients with TBI were enrolled in the study, with rScO₂ ≥ 0.60 (grade I) in 14 patients, 0.50 ≤ rScO₂ < 0.60 (grade II) in 16 patients, and rScO₂ < 0.50 (grade III) in 12 patients. PAV 3-4 scores (grade I) were detected in 16 patients, 2 scores (grade II) in 17 patients, and 1 score (grade III) in 9 patients. GCS score 9-14 (grade I) were observed in 13 patients, 4-8 (grade II) in 23 patients, and 3 (grade III) in 6 patients; 18 patients had poor prognosis and 24 had good one. The rScO₂, PAV and GCS scores of the poor-prognosis group were significantly higher than those in the good-prognosis group [rScO₂ with grade III: 55.6% (10/18) vs. 8.3% (2/24), PAV with grade III: 38.9% (7/18) vs. 8.4% (2/24), GCS score with grade III: 27.7% (5/18) vs. 4.1% (1/24)] with significant differences (all P < 0.05). There was no significant difference in other general data including gender, age, total length of hospital stay or acute physiology and chronic health evaluation II (APACHE II) score between the two groups. Binary multivariate Logistic regression analysis showed that rScO₂ and PAV were independent risk factors for prognosis of brain in patients with TBI [rScO₂: odds ratio (OR) = 4.656, 95% confidence interval (95%CI) was 1.071-20.233, P = 0.040; PAV: OR = 3.525, 95%CI was 1.044-11.906, P = 0.042]. ROC curve analysis showed that both of rScO₂ and PAV had predictive value for the prognosis of brain function in patients with TBI (AUC was 0.796 and 0.780, respectively, both P < 0.01), and rScO₂ combined with PAV had higher predictive value with the AUC of 0.851 (P < 0.01) than rScO₂ or PAV alone, the sensitivity was 94.4% and the specificity was 62.5%. CONCLUSIONS rScO₂ and PAV were associated with early brain function prognosis in patients with TBI. The combination of two monitoring indicators can reliably assess the prognosis of brain function in patients with TBI.

Objective To study the characteristics of positive expression of integrin β1 in the rat brain tissue of two kinds of traumatic brain injury models and to explore the feasibility of inferring the mode of traumatic brain injury using the positive expression of integrin β1. Methods The occipital region of rats was hit by hydraulic impact method and pendulum striking method to produce two closed brain injury models of linear and rotation acceleration respectively, then 120 SD rats were randomly divided into linear acceleration injury group, rotation acceleration injury group, sham operation group and normal control group. Immunohistochemistry staining and Western blotting method were used to detect the positive expression of integrin β1 in different parts of the brain tissue at 30 min, 3 h, 6 h, 12 h, 3 d and 7 d after rat injury. The data was processed statistically by SPSS 18.0 software. Results The positive expression of integrin β1 was detected 30 min after brain injury and reached the peak 6 h after brain injury. With the extension of injury time, the expression tended to enhance. At the same time points after injury, the differences in the positive expression of integrin β1 between the linear acceleration injury group and the rotation acceleration injury group in the occipital strike point and thalamus had no statistical significance （ P>0.05）, but the differences in the expression of integrin β1 in the frontal lobe and brain stem had statistical significance （P<0.05）. Conclusion The characteristics of positive expression of integrin β1 in brain tissue can be used to infer the strike point and the manner of injury and has application value for the reconstruction of craniocerebral injury process.

Given the lack of infrastructure in Papua New Guinea (PNG) traumatic brain injury (TBI) cases are usually not retrieved quickly to medical centres. Cases that eventually reach the hospital do so after the golden hour has passed. This means that the brain is already at risk of or is already subject to secondary brain injury. In TBI, the parenchymal integrity of the normal, the penumbrous and the lacerated tissue needs to be kept in a state of balance, such that the normal tissue is not compromised. The whole aim of neuroprotection is to protect the normal brain parenchyma from further injury. Secondary brain injury is minimized by reducing cerebral oedema and intracranial pressure, in order to improve cerebral blood flow and perfusion. This guideline describes the options for neuroprotection in PNG.

BACKGROUND: Traumatic brain injury (TBI) has been responsible for 25-30% of surgical deaths in Port Moresby General Hospital (PMGH) over the last 30 years despite being responsible for only 5% of the admissions. AIM: To document the epidemiology of TBI over a period of two years from 2003 to 2004 and compare this to the previous two decades in PMGH and elsewhere. The treatment and outcome of TBI cases are analyzed. METHODS: All TBI cases were included from January 2003 to December 2004. The Glasgow Coma Score (GCS) and Glasgow Outcome Scale (GOS) were documented at admission and discharge. These cases were followed up in the outpatient department for at least 6 months. RESULTS: There were 262 cases of TBI admitted between January 2003 and December 2004. There were 31 deaths during this period. 28 deaths were in the severe TBI category (GCS 3-8) and 3 in the moderate category (GCS 9-12). CONCLUSION: The case fatality rate of severe TBI has been reduced from 60% to just below 30% over the period of 2 years. The formation of a single unit managing TBI over two years may be one factor contributing to this improvement. Interpersonal violence has replaced motor vehicle accidents as the leading cause of death from TBI.

OBJECTIVE: To evaluate recovering consciousness effect of electroacupuncture (EA) on patients after traumatic brain injury (TBI) surgery. METHODS: A total of 100 patients with traumatic coma were randomly divided into an observation group and a control group, 50 cases in each group. The control group was mainly treated with awakening drugs and neurotrophic drugs; on the basis of treatment in the control group, the observation group was treated with EA at Neiguan (PC 6) and Shuigou (GV 26) with disperse-dense wave, 2 Hz/100 Hz in frequency, 0.1-5 mA in intensity. After 30 min of EA, the needles were stayed 60 min. The treatment was performed once a day for 14 consecutive days. The changes in Glasgow coma score (GCS) was observed in the two groups before treatment and after 7, 14 days of treatment; and the two groups were followed up for 3 months after treatment to evaluate the Glasgow outcome scale (GOS) and Barthel index (BI) scores. RESULTS: After 7, 14 days of treatment, the GCS scores of the two groups were higher than those before treatment (<0.05), and the increase degree in the observation group was significantly larger than that in the control group (<0.05). At 3 months of follow-up, the GOS and BI scores of the observation group were better than those of the control group (<0.05). CONCLUSION Early electroacupuncture intervention can effectively promote the recovery of consciousness after traumatic brain injury surgery, and has a curative long-term effect.

Although posttraumatic stress disorder (PTSD) is on the rise, traumatic events and their consequences are often hidden or minimized by patients for reasons linked to PTSD itself. Traumatic experiences can be broadly classified into mental stress (MS) and traumatic brain injury (TBI), but the cellular mechanisms of MS- or TBI-induced PTSD remain unknown. Recent evidence has shown that the morphological remodeling of astrocytes accompanies and arguably contributes to fearful memories and stress-related disorders. In this review, we summarize the roles of astrocytes in the pathogenesis of MS-PTSD and TBI-PTSD. Astrocytes synthesize and secrete neurotrophic, pro- and anti-inflammatory factors and regulate the microenvironment of the nervous tissue through metabolic pathways, ionostatic control, and homeostatic clearance of neurotransmitters. Stress or trauma-associated impairment of these vital astrocytic functions contribute to the pathophysiological evolution of PTSD and may present therapeutic targets.

Post traumatic epilepsy （PTE） refers to the epileptic seizures after traumatic brain injury. Organic damage can be found by imaging examination, and abnormal electroencephalogram can be detected via electroencephalogram examination which has the similar location of the brain injury. PTE has the characteristics of low incidence, absence of case reports, and easy to exaggerate the state of illness, which add difficulties to the forensic identification. This paper reviews the status of epidemiology, pathogenesis, clinical treatment and forensic identification for PTE.
