Objective:To investigate the risk factors of venous thromboembolism (VTE) in patients with severe traumatic brain injury (TBI).Methods:A retrospective case-control study was conducted for clinical data of 180 severe TBI patients admitted to West China Hospital, Sichuan University from July 2019 to July 2021, including 137 males and 43 females, aged 18-93 years [(50.8±18.2)years]. Glasgow Coma Scale (GCS) was 3-8 points [4 (3, 6)points].VTE was presented in 95 patients (thrombosis group), but was not seen in 85 patients (non-thrombosis group). Univariate analysis was used to detect the correlation of the following data with the occurence of VTE, inlcuding sex, age, body mass index (BMI), hypertension, diabetes, laboratory indicators measured on admission and at days 3-5 after admission [hemoglobin (Hb), platelet counts (PLT), antithrombin III, prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT), fibrinogen (FIB), D-dimer (D-D)], tracheal intubation or not, operation or not, volume of intraoperative blood transfusion, operation time, anesthesia time, admission to ICU or not, mechanical ventilation or not, pharmacological prophylaxis or not, deep venous catheterization or not, parenteral nutrition or not, tracheal intubation time, tracheotomy or not, pneumonia, stress ulcer, blood transfusion or not and hospital stays. Multivariate Logistic regression analysis was used to identify the independent risk factors for VTE.Results:Univariate analysis showed that the occurence of VTE was correlated with sex, laboratory indicators measured on admission (TT, FIB, D-D), tracheal intubation, operation, intraoperative blood transfusion, operation time, anesthesia time, admission to ICU, mechanical ventilation, laboratory indicators measured at days 3-5 after admission (PLT, TT, FIB, D-D), deep venous catheterization, parenteral nutrition, tracheal intubation, tracheotomy, pneumonia, blood transfusion and hospital stays (all P<0.05 or 0.01), not with age, BMI, hypertension, diabetes, laboratory indicators measured at admission (Hb, PLT, antithrombin III, PT, APTT), laboratory indicators measured at days 3-5 after admission (Hb, antithrombin III, PT, APTT), pharmacological prophylaxis and stress ulcer (all P>0.05). Multivariate Logistic regression analysis showed that higher FIB on admission ( OR=1.27, 95% CI 1.04-1.56, P<0.05), tracheal intubation ≥7 days ( OR=2.98, 95% CI 1.40-6.33, P<0.01), tracheotomy ( OR=2.49, 95% CI 1.11-5.60, P<0.05), blood transfusion ( OR=2.75, 95% CI 1.25-6.06, P<0.05) and hospital stays >14 days ( OR=3.05, 95% CI 1.36-6.85, P<0.01) were significantly related to the occurence of VTE. Conclusion:Higher FIB on admission, tracheal intubation ≥7 days, tracheotomy, blood transfusion and hospital stays >14 days are independent risk factors for the occurence of VTE in severe TBI patients.

Background and objective It has been proven that increase of the awareness level of lung cancer preven-tion and control could enhance participation of lung cancer screening of lung cancer high risk group. hTe aim of this study is to investigate the awareness level of lung cancer prevention and control and the effect of individual characteristics on lung cancer awareness, and to provide evidence for comprehensive lung cancer prevention in high risk areas of lung cancer. Methods Staffs of Tianjin Dagang Oil Field who participate low dose CT (LDCT) lung cancer screening by cluster sampling or according to voluntary principle were surveyed, data of lung cancer awareness were collected by questionnaire. Results A total of 1,633 valid questionnaires were collected. hTe average age of respondents was 60.08±6.58. Most participants were males (82.2%) while female only accounted for 17.8%. hTe proportions of awareness about lung cancer in China, risk factors, screening methods and the knowledge of health examination were 64.5%, 77.1%, 43.7%, 49.6%respectively. Result of multiple logistic regression analysis showed that education level, smoking (pack-year), age, prior tuberculosis were the inlfuencing factors of lung cancer awareness with adjusted Ors for education and age level as of 0.567 (95%CI:0.439-0.733) and 1.373 (95%CI:1.084-1.739) respectively. 80.3%of the participants can accept health examination once a year, while the ability to pay the medical expenses was not high. hTe inlfuencing factors of health examination willingness were gender, age, income, the knowledge of lung cancer. Conclusion Education level and smoking affect the awareness of lung cancer prevention and control, health education for lung cancer should be conducted especially in population with low education level. Comprehensive lung cancer control in high risk areas should combined lung cancer screening, tobacco control and health education.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
