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 observe the efficacy and safety of sacubitril valsartan in the treatment of dilated cardiomyopathy (DCM) in children. Methods A total of 19 hospitalized children with DCM were retrospectively selected as study subjects. All patients received captopril combined with conventional anti-heart failure therapy for 1 to 4 weeks, but due to ineffective treatment, they were switched to treatment of sacubitril valsartan. Clinical data, biochemical indicators, and echocardiographic findings were collected to assess changes in clinical symptoms and related indicators after 1-, 3-, 6-, and 12-month sacubitril valsartan treatment. Information on the dosage and administration of sacubitril valsartan, as well as the occurrence of adverse reactions was collected. Results Among 19 patients, there were 8 males and 11 females, with a median age of 3 years. Heart function was classified as grade Ⅱ in 2 patients, grade Ⅲ in 10 patients, and grade Ⅳ in 7 patients. At the final follow-up, the efficacy assessment showed significant improvement in 8 patients, effective improvement in 6 patients, and no improvement in 5 patients, with a total effective rate of 73.7%. After 1-, 3-, 6-, and 12-month sacubitril valsartan treatment, the levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) were lower, left ventricular ejection fraction (LVEF) was higher, and left ventricular diastolic diameter (LVDd)-Z value was smaller compared with those before treatment (P < 0.05). The initial single dose of sacubitril valsartan was 0.8 mg/kg, and the average maintenance dose was 1.7 mg/kg, administered twice daily. After treatment, 1 patient developed hypotension, and 5 patients exhibited mild abnormalities in renal function indicators (of which 4 recovered to normal levels after tolerance). Conclusion Sacubitril valsartan can effectively improve heart failure symptoms and cardiac function indicators in children with DCM, but close monitoring of blood pressure and renal function changes is required during treatment.

Objective:To study the protective effect and possible mechanism of psoralen corylifolia on non-alcoholic steatohepatitis (NASH) induced by high-fat diet in mice.Methods:The newly weaned female mice in the offspring of C57BL/6J mice fed with normal diet were selected as the control group (gavage of distilled water); the newly weaned female mice in the offspring of C57BL/6J mice fed with high-fat diet were randomly divided into model group (gavage distilled water), low-dose group[psoralen corylifolia 1.125 mg/(g·d)], high-dose group [psoralen corylifolia 2.25 mg/(g·d)] and vitamin E group [vitamin E 0.01 mg/(g·d)]. Six mice in each group were fed continuously for 8 weeks. Automatic biochemical analyzer was used to detect serum alanine aminotransferase (ALT), aspartate transaminase (AST), triglyceride (TG), total cholesterol (TC) level in mice; The liver tissue pathological changes were observed by hematoxylin-eosin (HE) and Sirius-red (SR) staining; The level of reactive oxygen species (ROS) in liver tissue was detected by dihydroethidium (DHE) fluorescence probe; the activity of NADPH oxidase was detected by kit; The protein expressions of nuclear factor-κB (NF-κB), phosphatidylinositol 3 kinase (PI3K p85), protein kinase B (Akt), P47 phox and protein kinase C-α (PKC-α) were detected by Western blot.Western blot. Results:The levels of serum ALT, AST, TG, TC and homeostasis model assessment of insulin resistance (HOMA-IR) index in the model group were higher than those in the control group (all P<0.01). After treatment, the levels of serum ALT, AST, TG, TC and HOMA-IR in low-dose group, high- dose group and vitamin E group were lower than those in model group (all P<0.05). HE and SR staining showed that hepatocytes in the model group were swollen, and there were lipid droplets of different sizes, vacuoles and obvious fibrosis. After treatment, hepatocyte steatosis and fibrosis decreased and the contents of ROS and NADPH oxidase in liver decreased(all P<0.05); Western blot showed that the p-p65/p65, p-Akt/Akt, p-PKC-α/PKC-α, PI3K, p85 and P47 phox protein expression in the model group were higher than those in the control group (all P<0.01). After treatment, the protein expression levels of p-p65/p65, p-Akt/Akt, p-PKC-α/PKC-α, PI3K, p85 and P47 phox decreased (all P<0.01). Among the above indexes, the protective effect of high-dose group on liver NASH was better than those of vitamin E group and low-dose group (all P<0.05). Conclusions:Psoralen corylifolia can improve the liver function of NASH model mice, which may be related to the inhibition of oxidative stress, inflammatory reaction and liver fibrosis, which provides a new idea for the prevention and treatment of children with NASH.

【Objective】 To investigate the role of dual-specific phosphatase 6 （DUSP6） in the regulation of human lens epithelial cells （HLECs） epithelial-mesenchymal transition （EMT） and extracellular matrix （ECM） synthesis induced by transforming growth factor β2 （TGF-β2）. 【Methods】 Human lens epithelial B3 （HLE-B3） cells were treated with 10 μg/L of TGF-β2 for 0 h，12 h， 24 h and 48 h. Then we detected the expressions of α-smooth muscle actin （α-SMA） and fibronectin （Fn） by real-time fluorescent quantitative PCR （RT-qPCR） and Western blotting. The overexpression vector of DUSP6 was constructed and transfected into HLE-B3 cell line and divided into three groups： TGF-β2， empty vector （EV）+TGF-β2， and DUSP6+TGF-β2. RT-qPCR and Western blotting were used to detect the effect of overexpression of DUSP6 on the expressions of α-SMA and Fn. Scratch test and Transwell migration test were used to evaluate the effect of DUSP6 overexpression on cell migration. 【Results】 Compared with the control group， the expressions of DUSP6 mRNA and protein decreased after 10 μg/L of TGF-β2 treatment for 24 h （P<0.05）. Compared with EV+TGF-β2 group， DUSP6+TGF-β2 group inhibited the migration of HLE-B3 cells and the expressions of α-SMA and Fn （P<0.05）. 【Conclusion】 DUSP6 could inhibit EMT and ECM synthesis in lens epithelial cells induced by TGF-β2， which might provide a potential therapeutic strategy for posterior capsule opacification.
