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.

The multiple myeloma (MM), the second most common hematologic malignancy, is malignant proliferative disease of plasma cells. Although the application of many targeted drugs has significantly prolonged the survival time of MM patients, it is still an incurable disease. In recent years, the immunosuppression caused by interaction between tumor microenvironment(TME) and tumor cells has attracted people's attention gradually. As a kind of immunosuppressive cells in TME, regulatory T cells (Treg) play an important role in the progress of MM. Treg is related to the proliferation and metastasis of tumors, and can lead to the progress of MM by promoting the angiogenesis and generating immunosuppressive TME. In this review, we briefly summarized the latest research progress on the impact of Treg on the pathogenesis of MM.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

Objective:To explore the possible mechanism of Astragali Radix-Curcumae Rhizoma （AC） in inhibiting tumor growth in the orthotopic transplantation model of colon cancer in mice. Method:The molecular docking technology was used to predict the intermolecular interaction between the main active components of AC and the pathway target proteins， such as stromal cell-derived factor-1 （SDF-1）， C-X-C motif chemokine receptor 4 （CXCR4）， and nuclear factor kappa-B p65 （NF-κB p65）. The orthotopic transplantation model of CT26.WT colon cancer was established in mice for in vivo experimental verification. Sixty BALB/c male mice were randomly divided into a sham operation group， a model group， a 5-fluorouracil （5-Fu， 30 mg·kg^-1） group，and low- （0.32 g·kg^-1）， medium- （0.64 g·kg^-1）， and high-dose （1.28 g·kg^-1） AC groups， with 10 mice in each group. The sham operation group and the model group received normal saline by gavage. The corresponding drugs were administered by gavage in the 5-Fu group and by intraperitoneal injection in the AC groups. After intervention for 15 days， the tumor in situ was completely stripped， and the colon tissues 5-6 cm in length adjacent to the tumor were taken. The tumor volume was measured and calculated. The pathological changes of tumor tissues and colon tissues were observed by Hematoxylin-Eosin （HE） staining. Western blot was used to detect the protein expression of SDF-1， CXCR4， p-NF-κB p65 in colon tissues. Western blot and Real-time quantitative polymerase chain reaction （Real-time PCR） were used to detect SDF-1， CXCR4， NF-κB p65， Cyclin D₁， oncogene c-Myc protein and mRNA expression in tumor tissues. Result:Compared with the model group， 5-Fu and AC groups showed reduced tumor volumes in situ （P<0.05， P<0.01）， with the tumor inhibition rate in the 5-Fu group as high as （61.38±2.34）%. The tumor-inhibiting effect was optimal in the medium-dose AC group， with the tumor inhibition rate of （43.43±3.71）%. Compared with the model group， 5-Fu and AC groups showed relieved pathological changes of tumor and colon tissues. Specifically， AC down-regulated the protein expression levels of SDF-1， CXCR4， and p-NF-κB p65 in colon tissues （P<0.01）， and down-regulated the protein and mRNA expression levels of SDF-1， CXCR4， NF-κB p65， Cyclin D₁， and c-Myc in tumor tissues （P<0.05， P<0.01）. Conclusion:AC can inhibit the growth of orthotopic transplantation tumor of colon cancer， and its intervention mechanism may be related to the regulation of related protein and mRNA expression in the SDF-1/CXCR4/NF-κB signaling pathway.

OBJECTIVE: To study the association between maternal alcohol consumption and the risk of congenital heart disease (CHD) in offspring. METHODS: PubMed, Cochrane Library, Web of Science, Google Scholar, China Biology Medicine disc, Wanfang Database, CNKI Database, and Weipu Database were searched for the articles on the association between maternal alcohol consumption and congenital heart disease in offspring. These articles were published up to November 30, 2019. A random effects model or a fixed effects model was used for the pooled analysis of the results of each study, and then the pooled effective value and its 95%CI were calculated. A subgroup analysis was performed to explore heterogeneous regulators. Funnel plots and an Egger's test were used to assess publication bias. RESULTS: A total of 4 409 articles were searched, and 55 articles were finally included in this analysis, among which there were 6 cohort studies and 49 case-control studies. The Meta analysis showed heterogeneity across all studies (I=74%, P<0.01). The random effects model showed that maternal alcohol consumption was associated with CHD in offspring, with an OR of 1.18 (95%CI: 1.09-1.28). The Egger's test showed a certain degree of publication bias (P<0.05), and after adjustment, the pooled OR of CHD in offspring was 1.10 (95%CI: 1.01-1.21). CONCLUSIONS Maternal alcohol consumption may increase the risk of CHD in offspring.

BACKGROUNDTendon adhesion is one of the most common causes of disability following tendon surgery. Therefore, prevention of peritendinous adhesion after surgical repair of tendon is a major challenge. The aim of this study was to explore the possible application of a collagen membrane for the prevention or attenuation of peritendinous adhesions.

METHODSSprague-Dawley (SD) rat Achilles tendon was cut and sutured by a modified Kessler's technique with or without the collagen membrane wrapped. Macroscopic, morphological and biomechanical evaluations were applied to examine the recovery of the injured tendon at 4 and 8 weeks after surgery.

RESULTSThe surgery group wrapped by collagen membranes had a better outcome than the group with surgery repair only. In the collagen membrane-treated group, less adhesion appeared, stronger tensile strength was detected, and more tendon fibers and collagen I expression were observed morphologically.

CONCLUSIONWrapping the tendon with a collagen membrane may be an efficient approach for tendon repair and preventing tendon adhesion after its ruptures.
