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.

Objective To evaluate the effects of intermittent hypoxia-reoxygenation(IHR)on body weight,diet and water intake,circulating metabolites,and responses to central leptin injection in a rat model of diet-induced obesity(DIO).Methods Rat models of DIO established by 12-week high-fat diet(HFD)feeding were randomized into normoxia group(n=15),intermittent hypoxia group(6％O2,30 cycles/h,8 h/day for 4 weeks;n=15),and IHR group(2 weeks of intermittent hypoxia followed by 2 weeks of reoxygenation;n=15).Body weight,diet and water intake of the rats were recorded,and circulating leptin,IL-6,and Ang-Ⅱ levels were detected.After IHR treatment,the rats received intracerebroventricular injection of 4 μg leptin,and the hypothalamus and liver were taken 1 h later for detecting POMC,FRA-1 and FRA-2 expressions in the hypothalamus using immunohistochemistry,POMC,pSTAT3 and LepR expressions in the hypothalamus using Western blotting,and LepR mRNA expression in the hypothalamus and liver using RT-PCR.Results The rats in intermittent hypoxia group showed significantly increased weight gain,food intake and elevated systemic inflammatory cytokine levels.Intermittent hypoxia obviously inhibited the expression of POMC,lowered the expressions of FRA-1 and pSTAT3,reduced the responsiveness of the rats to exogenous leptin,and downregulated the mRNA and protein expression of LepR.Two weeks of reoxygenation treatment obviously reduced intermittent hypoxia-induced weight gain and metabolic disorder and improved leptin sensitivity of the rats.Conclusion Prolonged intermittent hypoxia impairs hypothalamic leptin signaling by downregulating LepR expression to promote weight gain in obese rats,which can be improved by reoxygenation treatment.

Objective To observe the clinical manifestations of 3 cases with myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease and anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis antibody overlapping syndrome (MNOS), aiming to expand the understanding of the clinical spectrum of such syndromes. Methods Retrospective analysis was performed on the data of 3 patients with MNOS who were positive for both MOG antibodies and NMDAR antibodies. Clinical features, neuroimaging characteristics, and outcomes were collected, and cell-based assay (CBA) technique was used for diagnosis. Results One case presented both positive MOG antibodies and NMDAR antibodies, but the clinical manifestations were typical symptoms of anti-NMDAR encephalitis. In one case, the clinical and cranial magnetic resonance imaging (MRI) features of demyelinating disease recurred after anti-NMDAR encephalitis, with atypical symptoms of MNOS such as numbness and weakness in limbs, blurred vision, and diplopia. The last case presented both positive MOG antibodies and NMDAR antibodies, but the clinical manifestations were typical symptoms of anti-NMDAR encephalitis. In MNOS, MOG antibody-associated disease and anti-NMDAR encephalitis may appear simultaneously or sequentially, with epilepsy being the most common symptom. Cranial MRI findings showed that the patients presented and mainly involved supratentorial lesions, which may also involve the brainstem, but no spinal cord lesions were found. All patients showed slightly abnormal cerebrospinal fluid. Patients showed a good response to first-line immunotherapy during the acute phase of the disease, with a favorable prognosis. But most patients were prone to relapse. Conclusion In MNOS patients, anti-NMDAR encephalitis may present with clinical and(or)MRI features of demyelinating disease simultaneously or sequentially. The clinical manifestations of patients are complex and diverse. Patients with atypical symptoms require to improving the understanding of MNOS and timely treatment.

OBJECTIVE: To compared the effect of different drying methods on drying characteristics, water effective diffusion coefficient and biased activation energy of Codonopsis Radix and to definite 3 different drying methods of varying temperature(45-55-60, 60-55-45, 60-45-60℃) and 3 constant temperature(45, 55, 60℃) on drying characteristic curves of different commercial grades of Codonopsis Radix. METHODS: Used R2, χ2 and RMSE as evaluation indexes, 10 typical drying kinetic models were selected to fit the drying curve of Codonopsis Radix, and the effective moisture diffusion coefficient and biased activation energy under different drying method were calculated. RESULTS: It was found that the Midilli model could well describe the drying process of different commercial grades of Codonopsis Radix, the water ratio of Codonopsis Radix showed an exponential downward trend. If the initial drying temperature was set above 55℃, the maximum drying rate could be reached within 2 h. And commercial grades temperature had certain influence on the effective water diffusion coefficient of Codonopsis Radix. Under the same temperature condition, the average speed of moisture migration during drying of Codonopsis Radix was:first-class> second-class>third-class, and the Deffwere 10.433 9×10-8, 5.545 2×10-8, 2.249 6×10-8·m2·s, respectively. The calculated bias activation energy of Codonopsis Radix was 2.943×104-4.378×104 J·mol-1, the order of bias activation energy of different drying methods was as follows:60-55-45℃ variable temperature<60-45-60℃ variable temperature<45-55-60℃ variable temperature<55℃ constant temperature<60℃ constant temperature <45℃ constant temperature, which indicated that the moisture in the medicinal materials was more likely to evaporate and overflow and consumes less energy than the constant temperature drying. In particular, the bias activation energy of 60-55-45℃ drying method was 77.54% and 81.86% of the other 2 variable temperature drying methods, which were 67.22%, 75.13% and 74.26% of the 3 kinds of constant temperature drying. CONCLUSION The use of cooling mode in the drying process can save more time and energy, and can provide experimental basis for the improvement of drying technology and optimization of drying process of Codonopsis Radix.

Objective: To improve clinical management of maternal and neonatal listeriosis through analyzing the clinical characteristics and antibiotic treatment. Methods: A retrospective analysis of 26 cases of listeriosis, including their demographic and clinical features, was conducted, involving 16 pregnant women from Civil Aviation General Hospital, Xiamen Humanity Hospital, Tongzhou Maternal and Child Health Hospital of Beijing, Beijing Tiantan Hospital, Tangshan Maternal and Child Health Hospital, the Fourth Hospital of Tianshui City from October, 2011 to May, 2018, and 10 newborns from the Fourth Hospital of Tianshui City, Tangshan Maternal and Child Health Hospital, Zhengzhou Children's Hospital from February, 2016 to April 2018. Descriptive methods were used for data analysis. Results: (1) Among the 16 gravidas, one, five and 10 developed the infection in the 1st, 2nd and 3rd trimester of pregnancy, respectively, and eight had pregnancy complications. Furthermore, all of them developed fever [(38.9±0.5) ℃]. Symptoms such as cough, nasal congestion, runny nose, sore throat, dizziness, headache and other flu-like symptoms were observed in six cases. Gastrointestinal symptoms and flu-like symptoms were presented in four. Fetal distress, tachycardia and decreased fetal movement occurred in 11 cases. Elevated C-reactive protein and white blood cell count were detected in 16 and 14, respectively. Eight underwent placental pathological examination which shown various degrees of pathological changes, including neutrophil infiltration, acute chorioamnionitis and inflammatory necrosis. The main empirical antibiotic treatment for the 16 patients was cephalosporins and only four covered Listeria monocytogenes. Only two delivered at term, while the others (14/16) ended in miscarriage, premature delivery or stillbirth. (2) Among the 10 newborns with listeriosis, there were eight early-onset infections and two late-onset infections. All of them were febrile [(38.6±0.6)℃]. Six had cyanosis, groaning, foaming and three concave sign; five showed shortness of breath; meningitis and skin rash were found in one, respectively. All had elevated white blood cell and C-reactive protein. Six received antibiotics covering Listeria monocytogenes during the initial empirical treatment. Four were treated with cephalosporins alone, one of which died after the treatment was withdrawn. One was cured by initial treatment with meropenem alone, while eight recovered after adjustment of treatment with ampicillin, penicillin, meropenem, vancomycin alone, or meropenem combined with ampicillin or vancomycin. (3) The isolates that were susceptible to penicillin, ampicillin and meropenem accounted for 96.1% (25/26) all together and 88.5% (23/26) were susceptible to compound sulfamethoxazole. Conclusions There is no specific clinical manifestations of maternal or neonatal listeriosis. Maternal listeriosis is often characterized by acute onset and high incidence of adverse pregnancy outcomes.
