The current situation of knowledge, attitude and practice about target temperature management in patients with severe traumatic brain injury among intensive care unit nurses and its factors analysis / 中国实用护理杂志

Objective:To understand the current situation of knowledge, attitude and practice about target temperature management (TTM) in patients with severe traumatic brain injury (STBI) among intensive care unit ICU nurses and analyze the influencing factors, so as to provide a reference for conducting ICU nurses′ TTM training for patients with STBI.Methods:Applying the method of cross-sectional study, from November to December 2022, a stratified whole-group sampling method was used, stratified by first-, second-, and third-level hospitals, and a self-designed questionnaire on the current status of ICU nurses′TTM for patients with STBI was used to investigate the current status of knowledge, attitude, and practice of neurosurgical ICU, emergency ICU, and comprehensive ICU nurses in 22 second- and third-level hospitals in 11 cities in Gansu Province, and multiple linear regression analysis was used to analyze the factors influencing ICU nurses′ knowledge, attitude, and practice scores.Results:A total of 543 valid questionnaires were returned, and the scores of ICU nurses on the TTM total score, knowledge, attitude and practice dimensions of STBI patients were (76.75 ± 10.42), (7.38 ± 2.74), (39.57 ± 4.87), (29.80 ± 7.18) points respectively. The results of multiple linear regression analysis showed that the factor influencing ICU nurses′ scores on the TTM knowledge dimension for STBI patients was having attended TTM-related training ( t = 2.16, P<0.05); the factors influencing ICU nurses′ scores on the TTM attitude dimension for STBI patients were college, bachelor′s degree and the position of nurse practitioner ( t = 2.65, 2.91, 2.14, all P<0.05); and the factors influencing ICU nurses′ scores on the TTM practice dimension for STBI patients were the age group of 36 to 45 years old, the department having TTM-related criteria and having knowledge of TTM-related guidelines ( t = -2.46, 2.64, 3.85, all P<0.05). Conclusions:ICU nurses have a more positive attitude toward TTM in patients with STBI, but the level of knowledge and practice needs to be improved. Managers should conduct relevant training according to the current situation and influencing factors to improve ICU nurses′ knowledge and practice of TTM in patients with STBI, ensuring the effectiveness and safety of TTM.

Continuous monitoring of intracranial pressure and partial oxygen pressure of brain tissue in patients with severe traumatic brain injury after standard decompressive craniectomy and microscopic hematoma removal / 中国综合临床

Objective:To investigate the effect of continuous intracranial pressure (ICP) and brain oxygen partial pressure (PbtO 2) monitoring and guiding treatment after the application of standard large bone flap decompression and microhematoma removal in patients with severe traumatic brain injury (TBI). Methods:A retrospective analysis was done of 41 patients with TBI in Department of Neurosurgery in the Inner Mongolia People's Hospital from January 2018 to May 2020. Patients with Glasgow coma scale (GCS)<8 points were treatesd with microscopical removal of hematoma and contusion brain tissue and standard large bone flap decompression. Intraoperative intracranial pressure and brain tissue oxygen partial pressure monitoring probes were placed. Postoperatively, continuous intracranial pressure monitoring and partial oxygen pressure monitoring of brain tissue were performed, and target-based treatment under ICP and PbtO 2 monitoring was performed. According to the Glasgow Outcome (GOS) score after six months, patients were divided into a good outcome group (4-5 scores) and a poor outcome group (1-3 scores). There were 26 cases in good prognosis group and 15 cases in poor prognosis group. Linear regression analysis was used to further evaluate the relationship between PbtO 2, ICP and GOS score. The measurement data of normal distribution were compared by independent sample t-test. The counting data were expressed in cases (%), and the comparison between groups was adopted χ 2 inspection. The general linear bivariate Pearson correlation test was used. Results:The mean value of PbtO 2 (17.42±5.34) mmHg in the poor prognosis group was lower than that in the good prognosis group (24.65±5.61) mmHg, with statistical significance ( t=4.04, P<0.001). The mean value of ICP (22.32±3.45) mmHg in the poor prognosis group was higher than that (17.32±3.23) mmHg in the good prognosis group, with statistical significance ( t=4.15, P<0.001). Using PbtO 2 and ICP as independent variables and GOS score after 6 months as dependent variable, a regression equation was established ( Y=4.040 X+7.497; Y=-2.549 X+28.63). The mean value of PbtO 2 was positively correlated with GOS scores after 6 months in patients with severe head injury ( r=0.75, P<0.001). The mean value of ICP was negatively correlated with the prognosis of patients with severe head injury ( r=-0.87, P<0.001). Conclusion:The treatment guided by ICP combined with PbtO 2 monitoring is valuable in improving the prognosis of patients with severe traumatic brain injury after standard decompressive craniectomy, and may improve the prognosis 6 months after the injury.

Effects of enteral nutrition beginning at different time on aspiration rate and immune function in patients with severe traumatic brain injury / 中国康复理论与实践

@#Objective To investigate the effect of enteral nutritional support beginning at different time on aspiration events and immune function in the early post-traumatic (within 14 days) period in patients with severe traumatic brain injury.Methods From June, 2018, to February, 2021, 75 patients with acute traumatic brain injury admitted in the Department of Neurosurgery of the Second People's Hospital of Lianyungang were randomly divided into early feeding group (24 to 48 hours, n=35) and delayed feeding group (48 to 120 hours, n=40). The 14-day reflux rate, aspiration rate, incidence of aspiration pneumonia, immune indexes and complications were compared between two groups.Results There was no significant difference in the reflux rate, aspiration rate and the incidence of aspiration pneumonia between the two groups (P > 0.05). The levels of IgG, IgA, and complements C3 and C4 were significantly higher in the early feeding group than in the delayed feeding group (|t| > 1.720, P<0.001). The incidence of non-aspiratory lung infections was significantly lower in the early feeding group than in the delayed feeding group (χ2=4.728, P<0.05).Conclusion Initiating enteral nutrition within 24 to 48 hours after injury may preserve immune function and reduce the incidence of non-aspiratory lung infections in patients with severe traumatic brain injury.

Glasgow coma score combined with optic nerve sheath diameter in predicting the risk of death from cerebrocardiac syndrome / 中华急诊医学杂志

Objective:To explore the value of Glasgow coma score (GCS) combined with optic nerve sheath diameter (ONSD) in predicting the death risk of patients with cerebrocardiac syndrome (CCS).Methods:From January 2021 to September 2021, 83 patients with CCS secondary to severe traumatic brain injury (sTBI) in our hospital were collected and divided into a survival group ( n = 37) and death group ( n = 46) according to CCS-related death. The clinical data including age, sex, underlying diseases, head CT imaging manifestations, electrolytes, blood glucose, C-reactive protein (CRP), neuron-specific enolase (NSE), lactate dehydrogenase (LDH), creatine kinase (CK), creatine phosphokinase isoenzyme (CKMB), intracranial pressure (ICP), ONSD, cardiac color ultrasound, acute physiology and chronic health evaluationII (APACHEⅡ ) and GCS were analyzed and compared between the two groups. The proportion and dosage of vasoactive drugs used at admission, daily fluid balance volume during hospitalization, total amount of sedative and analgesic drugs, and average daily dose were analyzed and compared between the two groups. The independent risk factors for CCS-related death were analyzed using multivariate logistic regression. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of the independent risk factors in CCS-related death. Results:In this study, 55.4% of the patients died of CCS. The ONSD, ICP change rate, right ventricular Tei index and NSE in the death group were higher than those in the survival group, with statistically significant differences ( P < 0.05), while the GCS in the death group was significantly lower than that in the survival group, with a statistically significant difference ( P < 0.01). ONSD ( OR = 23.890, 95% CI: 5.526-103.286, P < 0.001), GCS ( OR = 17.066, 95% CI: 1.476-197.370, P = 0.023) and ICP change rate ( OR = 0.060, 95% CI: 0.007-0.477, P = 0.008) were the independent risk factors for CCS-related death. The area under the ROC curve (AUC = 0.897) of ONSD combined with GCS in evaluating CCS-related death was larger than that of ONSD, ICP change rate alone and the corresponding AUC of 1/GCS (0.876, 0.785, 0.800, respectively), with the advantages of non-invasive, dynamic monitoring and low inspection costs. Conclusions:The mortality rate of CCS is high. ONSD, GCS and ICP change rates are independently correlated with the death of CCS patients. ONSD combined with GCS is an ideal indicator for clinical prediction of CCS-related death.

Objective:To observe the effects of the Chinese medicine prescription Xiao-Cheng-Qi decoction (XCQD) on acute brain edema and inflammatory factors in rats with severe traumatic brain injury (sTBI).Methods:A total of 108 male Sprague-Dawley (SD) rats were divided into control group, sham operation group, sTBI model group, and XCQD low, medium, high dose groups by random number table method, with 18 rats in each group. sTBI rat model was prepared according to the modified Freeney method. At 6 hours after injury, the XCQD low, medium, and high dose groups were given XCQD 1.80, 2.78, and 4.59 g/kg by gavage, respectively, and the other three groups were given the same amount of normal saline, once a day for 3 days. After 3 days of injury, rats in each group were sacrificed after the modified neurologic severity score (mNSS) assessed. Pathological changes of brain tissue were observed under light microscope after hematoxylin eosin (HE) staining, water content of brain tissue was measured by dry-wet specific gravity method, and the expressions of aquaporin 4 (AQP4), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in brain tissue were detected by Western blotting. Serum TNF-α and IL-1β levels were detected by enzyme linked immunosorbent assay (ELISA).Results:Compared with the normal group, the mNSS score of rats increased significantly, the structure of brain tissue was disordered, and pathological changes appeared such as inflammation, edema, pyknosis of nerve nuclei, water content, the protein expressions of AQP4, TNF-α and IL-1β in brain tissue, and the contents of TNF-α, IL-1β in serum were significantly increased. After XCQD intervention, the above indexes were significantly improved. Compared with sTBI model group, the mNSS score of XCQD medium and high dose groups significantly decreased (6.94±1.16, 6.88±1.02 vs. 8.61±1.09, both P < 0.05), and the pathological changes such as brain edema and inflammation were alleviated. Brain tissue water content, AQP4 protein expression and contents of serum TNF-α, IL-1β in XCQD low, medium, and high dose groups significantly decreased compared with sTBI model group [brain tissue water content: (78.25±0.71)%, (77.62±0.44)%, (76.70±0.74)% vs. (80.08±0.66)%; the expression of brain AQP4 protein (AQP4/β-actin): 0.86±0.13, 0.84±0.22, 0.65±0.13 vs. 1.08±0.14; serum TNF-α (ng/L): 106.34±15.07, 95.75±17.26, 89.00±17.36 vs. 141.96±29.47; serum IL-1β (ng/L): 90.41±12.88, 72.82±13.51, 71.32±16.79 vs. 128.57±22.56, respectively, all P < 0.05]. The protein expressions of TNF-α,IL-1β in brain tissue of XCQD medium and high dose groups also significantly decreased compared with sTBI model group [TNF-α (TNF-α/β-actin): 0.90±0.24, 0.79±0.35 vs. 1.17±0.15; IL-1β (IL-1β/β-actin): 0.91±0.21, 0.68±0.28 vs. 1.23±0.08, respectively, all P < 0.05]. Brain tissue water content, the expression of brain AQP4 protein, the levels of brain tissue and serum IL-1β in XCQD high dose group improved more significant than those of XCQD low dose group. Conclusions:XCQD can alleviate the acute brain edema in sTBI rats, and it is dose-dependent. The mechanism may be relevant to reduce the secondary inflammatory response of sTBI by inhibiting the expression of inflammatory factors TNF-α and IL-1β.

Effect of early mechanical ventilation on the expression of inflammatory factors and prognosis in patients with severe traumatic brain injury / 中华危重病急救医学

Objective:To observe the effect of early mechanical ventilation on the expression of inflammatory factors and prognosis of patients with severe traumatic brain injury (sTBI).Methods:From January 2017 to December 2020, 138 patients with sTBI admitted to the department of the emergency of Xinhua Hospital Chongming Branch were enrolled. Although some patients were admitted to hospital without acute respiratory failure, their Glasgow coma score (GCS) were less than 8, they bad risk of hypoxia, so early mechanical ventilation was required. According to the patient's condition and the willingness of family members, patients were divided into mechanical ventilation group (tracheal intubation mechanical ventilation) and conventional oxygen inhalation group (nasal catheter or mask oxygen inhalation) in the end. The arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2), oxygenation index (PaO 2/FiO 2), tumor necrosis factor-α (TNF-α), and interleukin (IL-6, IL-10) levels at admission, preoperation and 72 hours postoperation, as well as GCS before operation and 1 week after operation, the duration and number of patients successfully evacuated from the ventilator within 1 week after surgery were observed and analyzed. Results:A total of 138 sTBI patients were enrolled in the study, including 72 cases in the mechanical ventilation group and 66 cases in the routine oxygen inhalation group. In the two groups, PaO 2, PaO 2/FiO 2 and IL-10 were higher, and PaCO 2, TNF-αand IL-6 were lower at 72 hours post operation than that before operation. Moreover, the changes in the mechanical ventilation group were more significant than those in the conventional oxygen inhalation group [PaO 2 (1 mmHg = 0.133 kPa): 94.6±7.7 vs. 92.5±6.8, PaO 2/FiO 2 (mmHg): 351±94 vs. 319±89, IL-10 (ng/L): 8.2±2.7 vs. 7.4±1.8, PaCO 2 (mmHg): 35.6±1.8 vs. 37.5±2.7, TNF-α(ng/L): 71.5±6.3 vs. 96.8±15.5, IL-6 (ng/L): 10.8±3.9 vs. 14.4±6.5, all P < 0.05]. There were 17 patients with severe respiratory insufficiency or failure in the conventional oxygen inhalation group before operation. Compared with the conventional oxygen inhalation group, the GCS score (11.7±3.1 vs. 9.1±4.6) and the proportion of successful weaning [62.5% (45/72) vs. 44.0% (29/66)] were significantly higher, and the duration of successful weaning (hours: 63.5±28.6 vs. 88.1±33.9) was significantly shorter in the mechanical ventilation group 1 week after operation. Conclusion:Early mechanical ventilation in sTBI patients can significantly improve oxygen supply, inhibit the release of pro-inflammatory factors, reduce secondary brain damage, and effectively improve the prognosis.

Combination of apparent diffusion coefficient and amplitude-integrated electroencephalogram to predict the outcome of comatose patients with severe traumatic brain injury / 中华危重病急救医学

Objective:To examine whether the combination of quantitative regional apparent diffusion coefficient (ADC) and amplitude-integrated electroencephalogram (aEEG) can predict the outcome of comatose patients with severe traumatic brain injury (sTBI).Methods:A prospective study was conducted. The patients with coma caused by sTBI [Glasgow coma scale (GCS) < 8] admitted to Suqian First Hospital from January 2016 to June 2019 were enrolled. All patients underwent aEEG examination and magnetic resonance imaging (MRI) scan within 1 week after emergency treatment. The ADC values of 9 regions of interest (frontal gray matter and white matter, parietal gray matter and white matter, temporal gray matter and white matter, caudate nucleus of basal ganglia, lenticular nucleus and thalamus) were measured by head MRI, and the mean ADC values of frontal lobe, parietal lobe, temporal lobe and basal ganglia were calculated respectively. According to the follow-up results after 12 months, the differences of each index between patients with poor prognosis [Glasgow outcome score (GOS) 1-2] and patients with good prognosis (GOS 3-5) were compared; the receiver operating characteristic curve (ROC curve) was drawn to evaluate the predictive ability of aEEG and ADC for the good prognosis of patients with sTBI, and the predictive value of the combination of aEEG and ADC.Results:A total of 52 patients with sTBI were enrolled, with mean age of (36.7±13.9) years old, 35 of whom were male. Within 12 months follow-up, 29 patients had achieved favorable outcomes and 23 patients had unfavorable outcome. There were 21, 17 and 14 patients with aEEG , and grade, respectively, and 19, 10 and 0 patients had good prognosis respectively. ADC values of 9 regions of interest in patients with good prognosis were significantly higher than those in patients with poor prognosis (×10 -6 mm 2/s: 924±107 vs. 531±87 in frontal gray matter, 804±95 vs. 481±74 in frontal white matter, 831±93 vs. 683±72 in temporal gray matter, 726±87 vs. 654±63 in temporal white matter, 767±79 vs. 690±75 in parietal gray matter, 716±84 vs. 642±62 in parietal white matter, 689±70 vs. 465±68 in caudate nucleus, 723±84 vs. 587±71 in lenticular nucleus, 807±79 vs. 497±67 in thalamus, all P < 0.01). ROC curve analysis showed that the area under ROC curve (AUC) of aEEG for predicting good prognosis of sTBI patients was 0.826, when the cut-off value of aEEG was < 1.5, the sensitivity was 94.7% and the specificity was 72.8%. Among the ADC value prediction abilities in the interested areas, the prediction of ADC value in frontal lobe and basal ganglia area were better than that in sTBI patients. AUC was 0.817 and 0.903 respectively. The best cut-off values were > 726×10 -6 mm 2/s and > 624×10 -6 mm 2/s respectively, the sensitivity of predicting prognosis were both 100%, and the specificity was 63.4% and 61.8%. A model combining frontal ADC and basal ganglia ADC with aEEG was 91.0% sensitive and 93.7% specific for favorable outcome of sTBI patients. Conclusion:Combination of the quantitative measurement of regional ADC and aEEG may be useful for predicting the outcome of the patients with sTBI.

Their dosages of anti-shivering medicine, coagulation and intracranial pressure were recorded. The scores of Glasgow Outcome Scale Extended (GOSE) and the mortality one, six and twelve months after discharge were observed. Results:The incidence and severity were less in the observation group than in the control group (χ2 = 16.212, P < 0.01). The dosage of anti-shivering medicine was less in the observation group than in the control group (t > 1.269, P < 0.05). The hypercoagulation relieved significantly six hours after hypothermia in the observation group, and it was stable twelve hours after hypothermia. For the control group, the hypercoagulation relieved significantly twelve hours after hypothermia, and it was stable 24 hours after hypothermia. The intracranial pressure decreased more in the observation group than in the control group. The GOSE score and the mortality were less in the observation group than in the control group (t > 1.168, P < 0.05) one, six and twelve months after discharge. Conclusion:Application of self-warming blankets in intravascular hypothermia for sTBI may relieve shivering, hypercoagulation and intracranial pressure, to improve the outcome of patients.

Evaluation of red blood cell distribution width and platelet distribution width in combination with Glasgow Coma Score for the prognosis of patients with severe traumatic brain injury / 医学研究生学报

ObjectiveAt present, there are few studies on prognostic indicators for patients with severe traumatic brain injury (STBI). This paper aims to explore its significance by analyzing the demographic characteristics of patients with STBI, as well as parameters such as clinical laboratory test indicators.MethodsA retrospective analysis was performed on 139 STBI patients admitted to the Department of Emergency Medicine, General Hospital of Eastern Theater Command from January 2017 to December 2018. According to the 28-day death event, the participants were divided into the survival group (n=108) and the death group (n=31). Indicators such as Glasgow Coma Score (GCS), red blood cell distribution width (RDW), platelet distribution width (PDW) and clot-related indicators were collected. Univariate and multivariate logistic regression were used to analyze the risk factors related to death, and receiver operating characteristic (ROC) curve was adopted to determine their prognostic values.ResultsThere were significant differences in GCS, RDW and PDW between the two groups. RDW (OR=4.577, 95% CI: 1.704-12.291), PDW (OR=1.346, 95% CI: 1.093-1.657) and GCS (OR=0.469, 95% CI: 0.301-0.730) were risk factors for death of STBI patients. The area under the curve (AUC) of RDW, PDW and GCS scores were 0.735 (0.640-0.840), 0.675 (0.553-0.796) and 0.737 (0.638-0.837), respectively, and the AUC of the combination of the three was 0.840 (0.748-0.932), which was significantly better than that of single diagnosis.ConclusionRDW, PDW combined with GCS can effectively evaluate the prognosis of patients with STBI, which has important guiding value for clinicians′ diagnosis and treatment.

Early tracheostomy in patient with severe traumatic brain injury clinical experiences in rural and remote areas

Background: Brain injury accounts for most of the causes of death from trauma. Brain injury is defined as a change in brain function, or brain pathology, caused by external forces. Patients with severe brain injury usually required rapid evacuation and special care in the Intensive Care Unit (ICU) room for respiratory control, mechanical ventilation, neurosurgical evaluation, and intracranial pressure monitoring (ICP). During admission to ICU, patients using tracheostomy, because it requires analgesia, sedation, and prolonged ventilation.Methods: Descriptive retrospective study conducted in February and March 2018 at Medical Record Installation of General Hospital Province of West Nusa Tenggara. The sample size is determined by consecutive sampling method.Results: Sample size were 60 people from medical record. Male patient more common than female (90 %). Based on Age more patients are 40 years old (43.3%). More Patient with early tracheostomy was survived (68,33%), and the rest died (31,67%).Conclusions: Severe head injury patients with tracheostomy are common at <18 years and >40 years. Patients with Severe brain injury who get early tracheostomy have more good outcomes, and have relatively short duration of ICU care.

Predictive value of serum HIF-1α and IL-6 on short-time prognosis of patients with severe traumatic brain injury / 中国神经精神疾病杂志

Objective To explore the predictive value of serum hypoxia-inducible factor-1α (HIF-1α) and interleukin-6 (IL-6) at admission on short-time 6-month prognosis of patients with severe traumatic brain injury (sTBI). Methods Seventy-two sTBI patients with Glasgow coma score (GCS) 3-8 points in our hospital were selected from September 2016 to January 2018 and divided into the group with good prognosis and group with poor prognosis according to Glasgow outcome score (GOS) after injury 6 months. Serum HIF-1α and IL-6 at admission were detected by using ELISA. The levels of plasma biochemistry indexes, acute physiology and chronic health evaluationⅡ(APACHEⅡ) scores and GCS scores were evaluated. Univariable and Multivariable COX proportional hazards models were performed to analyze the risk factors for short-time prognosis of patients with sTBI. Receiver operating characteristic (ROC) curve was built to analyze the predictive value of APACHEⅡ scores, HIF-1α and IL-6 on short-time prognosis of patients with sTBI. Results After 6-month followed up, there were 33 patients with good prognosis and 39 patients with poor prognosis. There was statistical difference of the baseline values of ages, serum HIF-1α and IL-6 at admission, APACHEⅡscores and GCS scores, the interval from injury to admission, the size of traumatic brain injury between two groups (t=2.312,14.132,16.628,3.172,3.644,3.073,4.284, P＜0.05). The serum HIF-1α [HR (95%CI)=2.645 (1.710-4.679), P＜0.05] and IL-6 [HR(95%CI)=1.821(1.674-2.957), P＜0.05] at admission, APACHEⅡscores [HR(95%CI)=1.789(1.105-2.928), P＜0.05] and the size of traumatic brain injury [HR (95%CI)=6.256 (1.727-10.834), P＜0.05] were the independent influence factors of short-time 6m prognosis of sTBI patients. The area under ROC curve and Youden＇s index of HIF-1α, IL-6 and APACHEⅡscores at admission on prediction of prognosis of sTBI patients were 0.94 (95% CI: 0.81-0.99) and 0.85, which was higher than separate predictive value of HIF-1α, IL-6 and APACHEⅡ scores. Conclusion The present study demontrated that serum HIF-1α and IL-6 at admission may be the early sensitive predictors of short-time prognosis in sTBI patients.

Diammonium glycyrrhizinate promotes the regeneration and repair of central nervous system in rats with severe traumatic brain injury by Wnt/β-catenin signaling pathway / 中华危重病急救医学

Objective@#To observe the effects of diammonium glycyrrhizinate (DG) on nerve regeneration repair in rats with severe traumatic brain injury (STBI) from the perspective of Wnt/β-catenin signaling pathway.@*Methods@#Seventy-two Sprague-Dawle (SD) male rats were randomly divided into normal group, STBI model group, ganglioside (GA) treatment group and DG treatment group. The STBI animal model was reproduced referring to modified Feeney free fall impact model. No injury was made in normal group. Six hours after modeling, monosialotetrahexosylganglioside sodium injection and DG injection were injected via tail vein of rats in GA treatment group and DG treatment group respectively, once a day for 7 days. Normal group and STBI model group were given the same amount of normal saline. Six rats in each group were sacrificed on the 1st, 3rd and 7th day after the challenge for neurological severity score (NSS), and then the blood of abdominal aorta was drawn and brain tissue was harvested. The contents of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in serum were detected by enzyme linked immunosorbent assay (ELISA). The pathological changes of sub-granular zone (SGZ) were observed under light microscope after hematoxylin eosin (HE) staining. Real-time quantitative reverse transcription-polymerase chain reaction (RT-qPCR) was used to detect the mRNA expressions of Wnt3a, β-catenin, glycogen synthetase kinase-3β (GSK-3β) and Axin.@*Results@#① There was no neurological deficit in the normal group and NSS was 0. NSS score of rats increased significantly on the first day after modeling, and then decreased gradually over time. NSS of the rats treated with GA and DG were significantly lower than that of the STBI model rats (score: 7.33±2.07, 6.17±2.23 vs. 9.33±1.63, both P < 0.01). Though NSS gradually decreased over time, the differences were still statistically significant on the 7th day (score: 2.67±0.82, 1.00±0.00 vs. 6.17±2.23, both P < 0.01), and NSS of DG treatment group was significantly lower than that of GA treatment group. ② In SGZ of rats, cells were arranged in a compact and orderly way in the normal group, but neurons and tissues were damaged and destroyed at different time points in the STBI model group. After either GA or DG treatment, the damage of nerve tissue was improved gradually over time, and the effect of DG was more obvious.③ In the normal group, the mRNA expressions of Wnt3a and β- catenin were almost not expressed, the mRNA expressions of GSK-3β and Axin were higher, and the contents of BDNF and NGF in serum were less. On the 1st day after STBI, the mRNA expressions of Wnt3a and β- catenin in hippocampus, the contents of BDNF and NGF in serum were significantly increased, and the mRNA expressions of GSK-3βand Axin were significantly decreased. The mRNA expressions of Wnt3a and β- catenin in the hippocampus and the contents of BDNF and NGF in serum were significantly higher than those in the model group 1 day after GA or DG was added, the mRNA expressions of GSK-3β and Axin were significantly decreased, and the effect of DG was more significant than that of GA [Wnt3a mRNA (2-ΔΔCt): 3.51±0.14 vs. 2.93±0.05, β- catenin mRNA (2-ΔΔCt): 1.90±0.08 vs. 1.75±0.04, BDNF (ng/L): 4.06±0.55 vs. 3.16±0.64, NGF (ng/L): 9.53±1.08 vs. 7.26±0.43, GSK-3β mRNA (2-ΔΔCt): 0.75±0.01 vs. 0.79±0.01, Axin mRNA (2-ΔΔCt): 0.74±0.02 vs. 0.76±0.02, all P < 0.05]. It was gradually increasing or decreasing over time and the difference was still statistically significant up to the 7th day.@*Conclusion@#DG can promote the recovery of nerve function in rats with STBI, and its mechanism may be related to the regeneration of nerve cells proliferation and differentiation by Wnt/β-catenin signaling pathway and the reconstruction of nerve tissue in SGZ of hippocampus.

Effect of long-term and short-term mild hypothermia in severe traumatic brain injury: a comparative study / 中华危重病急救医学

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.
