Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus disease 2019 (version 2023) / 中华创伤杂志

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.

Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults (version 2023) / 中华创伤杂志

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.

Effect of exosome / 中南大学学报(医学版)

Traumatic brain injury (TBI) is a main cause of death and disability worldwide, posing a serious threat to public health. But currently, the diagnosis and treatments for TBI are still very limited. Exosomes are a group of extracellular vesicles and participate in multiple physiological processes including intercellular communication and substance transport. Non-coding RNAs (ncRNA) are of great abundancy as cargo of exosomes. Previous studies have shown that ncRNAs are involved in several pathophysiological processes of TBI. However, the concrete mechanisms involved in the effects induced by exosome-derived ncRNA remain largely unknown. As an important component of exosomes, ncRNA is of great significance for diagnosis, precise treatment, response evaluation, prognosis prediction, and complication management after TBI.

Effect of epidural drainage and dural tenting suture on epidural hematoma in 145 cases of craniotomy / 中南大学学报(医学版)

Objective To evaluate the efficacy of dural tenting suture and epidural drainage in craniotomy. Methods In 145 cases of intracranial lesions, dural tenting suture and epidural drainage were performed to prevent epidural hematoma. Results Postoperative computed tomography (CT) showed no epidural hematoma required surgery in both groups. Conclusion Both dural tenting suture and epidural drainage are effective in preventing epidural hematoma. Hemostasis is the key step. Dural tenting suture without epidural drainage relieves psychological stress. It decreases the risk of intracranial infection and avoids some unusual complications.

Post-traumatic mutism in children.

OBJECTIVE: To explore the pathological mechanism of post-traumatic mutism (PTM) in children. METHODS: A retrospective study of 16 children who suffered from severe head injury and developed PTM. RESULTS: Post-traumatic coma lasted from 2-72 days, average 15.5 days; while post-traumatic mutism lasted from 2-56 days, average 11.94 days. The correlation between duration of coma and mutism was significant (p < 0.001). SPECT found that multiple persistent ischaemic brain regions occurred in all patients; the mean number of regions was 5.6. The patients were sub-divided into three groups based on the number of ischaemic regions: group 1, < or = 4; group 2, 5 approximately 6; group 3, > or = 7. The duration of mutism did not differ significantly between groups 1 and 2, but the difference between group 3 and the other two groups combined was significant (p < 0.05). CONCLUSION: Most PTM occurred in patients with diffuse brain injury. The duration of mutism was related to the number of ischaemic brain regions and the duration of post-traumatic coma.

Ventriculoperitoneal shunt for communicating hydrocephalus / 中国医师进修杂志

Objective To summarize the experience of the ventriculoperitoneal shunt (VPS) in communicating hydrocephalus and its complications. Methods The clinical features, operative techniques and outcome of 100 patients with hydrocephalus were analysed retrospectively. Results Ninety-five (95%) cases had a good result. Postoperative complications were found in 6(6%) cases including shunt apparatus blockage (4 cases) and shunt infection (2 cases). All the cases improved after taking the corresponding measures. Conclusion VPS is the most common shunt style for communicating hydrocephalus. The shunt apparatus blockage and infection are common postoperative complications. Intraoperative aseptic technique, the minimally invasive procedure, and the optimal placement of shunt tube may play an important role in improving the outcome of cerebrospinal fluid shunting surgery for communicating hydrocephalus.

Dynamic Changes of CT Scan of Focal Brain Edema After Head Injury / 中国医师杂志

Objective To study the dynamic changes of posttraumatic focal brain edema. Methods 120 patients who underwent multiple CT scans after head injury with hematoma or brain contusion in our hospital from 1998 to 2002 were enrolled in this study. Their CT image parameters and clinical data were recorded, and statistically analyzed. Results 96.7%(116/120) patients had perihematoma or pericontusion edema. Edema appeared 7 hours after head injury and reached its climax at the ninth day. Edema shape trended taper during its development, and cortex escaped from edema. Conclusion Focal brain edema was very common in the patient with head injury. Taper shape's formation and escape of cortex may mainly attribute to the difference in construction topology and blood supply between cerebral white and gray matter.
