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.

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.

Objective To analyze the spatial and temporal characteristics of hand, foot and mouth disease (HFMD) in Hunan Province from 2016 to 2020. Methods The data of HFMD in Hunan Province from 2016 to 2020 were collected from China's Disease Prevention and Control Information System. HFMD spatial autocorrelation analysis was conducted by ArcGIS 10.2 software at county level, and spatial-temporal scan statistical analysis was performed by SaTScan 9.7 software. Results A total of 714 157 cases was reported in Hunan Province during 2016-2020, with an average annual incidence rate of 208.36/100 000. Global spatial autocorrelation showed that HFMD had a positive spatial correlation on the county scale in Hunan Province during this period. Local spatial autocorrelation indicated that the hot spots were mainly concentrated in the north of central Hunan, the east of central Hunan and the west of Hunan. Spatial-temporal scanning analysis revealed the first class clusters (RR = 6.65, P< 0.001) covering 34 counties in northern and central Hunan, mainly distributed in Yueyang City, Changsha City, Zhuzhou City, Yiyang City and Xiangtan City from May 2018 to June, and the second class clusters (RR = 3.02, P < 0.001) covering 40 counties in western Hunan and central and southwest Hunan from April 2016 to June 2016. Conclusion HFMD incidence exhibits seasonal and regional characteristics in Hunan Province. The prevention and control of HFMD should be guided by combining the characteristics of spatial-temporal clustering.

Atherosclerosis is the pathological basis of a variety of cardiovascular and cerebrovascular diseases. Its complicated etiology and chronic course seriously threaten human health. The prevention and treatment of atherosclerosis have been the focus of traditional Chinese and western medicine. This paper reviews the pathogenesis characteristics of atherosclerosis, and holds that deficiency of vital qi is the pathogenesis basis of atherosclerosis, which involves deficiency of heart, spleen and kidney, mutual knot of phlegm and blood stasis, and obstruction of veins. In clinical treatment, the common treatment were summarized on the principle of "replenishing deficiency and removing phlegm and blood stasis". In order to understand the relationship between deficiency and phlegm and blood stasis and atherosclerosis from the perspective of Traditional Chinese Medicine. The paper provides a theoretical basis for Traditional Chinese Medicine prevention and treatment for atherosclerosis.

Obsessive-compulsive disorder (OCD) mainly manifests as obsessions and compulsions with the characteristics of early age of onset, long illness duration, and low diagnosis and treatment rate.The development of OCD involves mutations in genes associated with the 5-hydroxytryptamine, glutamate, and dopamine systems, as well as changes in the brain structure and function.However, how the potentially pathogenic genes affect brain structure and function and lead to different clinical manifestations remains unknown.Imaging genetics has been used to study the etiological mechanisms of OCD by combining genetics and imaging to analyze the relationship between genetic variation, neurologic and clinical manifestations.As a complex polygenic disease, imaging genetics that combines polygenic association analysis with epigenetic inheritance may become a new trend and perspective to explore the mechanism of the environment-gene-brain-behavior model in OCD.Therefore, this paper reviewed the related imaging genetics studies of OCD, and provided a theoretical basis for the etiological mechanism and precise intervention for OCD.

BACKGROUND:Understanding the actions and underlying mechanisms of proteins in cel s and organisms and studies on the lumbar disc herniation (LDH)-associated proteins contribute to further clarify the LDH pathogenesis. OBJECTIVE:To analyze the serum proteome changes in LDH patients using two-dimensional gel electrophoresis-tandem mass spectrometry, and to screen the biomarkers for LDH diagnosis and treatment. METHODS:Twenty-five LDH patients were enrol ed and their serums were col ected before and after treatment. After removal of high abundant protein, the serum protein spectrum was compared after two-dimensional gel electrophoresis serum protein spectrum diagram, to look for differential protein spots. Subsequently, the differential protein spots were identified by MALDI-TOF/TOF technique combined with biology software and database retrieval. RESULTS AND CONCLUSION:Six differential protein spots were screened preliminarily, and three kinds of proteins were confirmed after mass spectrum detection, among which, acid glycoprotein was related to the LDH immune regulation and occurrence, development and targeting sites of chemical radiculitis. The expression level of acid glycoprotein was significantly decreased in LDH patients after treatment (P<0.05). These results suggest that acid glycoprotein is associated with LDH through gel electrophoresis-base proteome analysis.

Objective To investigate the changing characteristics of myocardial movement in patients with dilated cardiomyopathy by three?di?mensional speckle tracking echocardiography(3D?STE). Methods The peak systolic global longitudinal train(GLS),global radial strain(GRS), global circumferential stain(GCS)and global area strain(GAS)of left ventricle were measured by 3D?STE technology in 69 patients with dilated cardiomyopathy. According to the left ventricular ejection fraction(LVEF),all patients were divided into group A(35%≤LVEF<50%)and group B (LVEF<35%). The differences of measurements were compared between two groups. The correlation between global myocardial strain in all direc?tions and left ventricular ejection fraction was analyzed. Results The GLS,GRS,GCS and GAS were significantly higher in group A than those in group B(P<0.01). The GLS,GRS,GCS and GAS were correlated with LVEF in group A(r=-0.871,0.610,-0.423,-0.797;P<0.05).The GCS,GRS and GAS were correlated with LVEF in group B(r=-0.517,0.368,-0.438;P<0.05). There was no significant correlation between GLS and LVEF in group B. Conclusion 3D?STE technology can be applied to evaluate the change of the myocardial movement. GLS is a promis?ing marker of the prognosis in patients with DCM.
