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.

OBJECTIVES: The high morbidity and mortality of colorectal cancer (CRC) have posed great threats to human health. Circular RNA (circRNA) and microRNA (miRNA), acting as competing endogenous RNAs (ceRNAs), have been found to play vital roles in carcinogenesis. This paper aims to construct a circRNA/miRNA/mRNA regulatory network so as to explore the molecular mechanism of CRC. METHODS: The sequencing data of circRNA from CRC were obtained from Gene Expression Omnibus (GEO). The differential circRNA was screened and its structure was identified by Cancer-specific CircRNA Database (CSCD); the sequencing data of miRNA and messenger RNA (mRNAs) were downloaded from The Cancer Genome Atlas (TCGA) database and the differentially expressed genes were screened; the corresponding miRNA of differential circRNAs were predicted by CircInteractome database; DIANA, Miranda, PicTar, and TargetScan databases were used to predict the target genes of different miRNAs; the target genes from Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were enriched by R language; String database combined with Cytoscape 3.7.2 software was used to construct protein-protein interaction (PPI) network and hub genes were screened; the expressions of mRNAs in the Top10 hub genes were verified in CRC. The network diagrams of circRNAs/miRNAs/mRNAs and circRNAs/miRNAs/Top10 hub mRNAs were constructed by Cytoscape3.7.2. Real-time PCR was used to examine the expression levels of hsa_circRNA_0065173, hsa-mir-450b, hsa-mir-582, adenylate cyclase 5 (ADCY5), muscarinic acetylcholine receptor M2 (CHRM2), cannabinoid receptor 1 (CNR1), and lysophosphatidic acid receptor 1 (LPAR1) in the CRC tissues and the adjacent normal tissues. RESULTS: A total of 14 differential circRNAs were identified, and 8 were found in CSCD; 34 miRNAs targeted by circRNAs were obtained. The PPI network was constructed, and the Top10 hub genes were identified, which were CHRM2, melanin concentrating hormone receptor 2 (MCHR2), G-protein gamma 3 subunit (GNG3), neuropeptide Y receptor Y1 (NPY1R), CNR1, LPAR1, ADCY5, adenylate cyclase 2 (ADCY2), gamma 7 (GNG7) and chemokine 12 (CXCL12), respectively. The expressions of Top 10 hub genes were also verified, and the results showed that the Top 10 hub genes were down-regulated in CRC; the constructed network diagram showed that hsa_circRNA_0065173 may regulate ADCY5, CHRM2, and Hsa-mir-450b by modulating hsa-mir-450b and hsa-mir-582. CNR1 and LPAR1 genes might serve as potentially relevant targets for the treatment of CRC. Real-time PCR results showed that the expression levels of hsa_circRNA_0065173, ADCY5, CHRM2, CNR1 and LPAR1 in the CRC tissues were significantly reduced compared with the adjacent normal tissues (all P<0.05); the expression levels of hsa-mir-450b and hsa-miR-582 were significantly increased (both P<0.05). CONCLUSIONS In this study, a potential circRNAs/miRNAs/mRNAs network is successfully constructed, which provides a new insight for CRC development mechanism through ceRNA mediated by circRNAs.

Background:In the clinical setting, the effect of intra-abdominal hypertension on the human body is dependent on time, but its role is not yet clear.Objective:To investigate the effect of the duration of intra-abdominal hypertension (IAH) on the prognosis of critically ill patients.Methods:This prospective cohort study enrolled 256 IAH patients who were admitted to the Surgical ICU of 10 Grade A hospitals in Fujian Province from January 2018 to December 2020. The duration of IAH (DIAH) was obtained after monitoring IAP, and ICU length of stay, duration of mechanical ventilation, duration of continuous renal replacement therapy (CRRT) and average daily energy intake from enteral nutrition during ICU stay were observed and recorded. The correlation was analyzed by Spearman rank correlation. The patients were divided into the survival group and the death group according to their survival state at 60 days after enrollment. Thereafter, clinical characteristics between the two groups were compared. Multivariable logistic regression was used to study and validate the relationship between DIAH and 60-day mortality. The receiver operating characteristics (ROC) curve was established to evaluate the predictive abilities of DIAH on the mortality risk.Results:In critically ill patients, DIAH was positively correlated with duration of mechanical ventilation ( r=0.679, P<0.001), duration of CRRT ( r=0.541, P<0.001) and ICU length of stay ( r=0.794, P<0.001), respectively. In addition, there was a negative correlation between DIAH and average daily energy intake from enteral nutrition ( r=-0.669, P<0.001). After multivariable adjustment, DIAH was an independent risk factor for 60-day mortality in critically patients with IAH ( OR=1.05, 95% CI: 1.01-1.12; P = 0.012), and exhibited a linearity change trend relationship with mortality risk. The ROC curve analysis of DIAH showed that the area under ROC curve (AUC) was 0.825 (95% CI: 0.763~0.886, P<0.01). When the cut-off value was 16.5 days, the sensitivity was 78.4% and the specificity was 75.4%. Conclusions:DIAH is an important risk factor for prognosis in critically ill patients. Early identification and rapid intervention for the etiology of IAH should be performed to shorten DIAH.

Objective:To evaluate the prognostic efficacy of the Chinese Group on the Study of Severe Hepatitis B (COSSH) acute-on-chronic liver failure (ACLF) II score (COSSH ACLF IIs) and associated risk stratification in predicting short-term prognosis of patients with hepatitis B virus-related ACLF (HBV-ACLF).Methods:Clinical data of 224 patients with HBV-ACLF admitted to the First Affiliated Hospital of Wannan Medical College and the First Hospital of Quanzhou, Fujian Medical University from January 2018 to December 2021 were retrospectively analyzed. The patients were divided into survival group ( n=171) and fatal group ( n=53) according to 28-day survival status. The values of the COSSH ACLF IIs, the Chronic Liver Failure-Consortium (CLIF-C) ACLF score (CLIF-C ACLFs), the CLIF-C organ failure score (CLIF-C OFs), the Model of End-stage Liver Disease (MELD) score (MELDs), the MELD-sodium score (MELD-Nas), and the Child-Turcotte-Pugh score (CTPs) for 28-day mortality prediction were compared using the area under the receiver operating characteristic curve (AUC). The patients were divided into groups according to COSSH ACLF classification and COSSH ACLF IIs risk stratification, respectively. The differences in 28-day mortality between groups were compared by Kaplan-Meir method, and the consistency of the two ACLF classification systems was compared by Kappa consistency test. Results:The AUC, sensitivity, and specificity of the COSSH ACLF IIs in 28-day mortality prediction were 0.885, 0.981 and 0.731, respectively. For predicting 28-day mortality, the COSSH ACLF IIs achieved a higher AUC than the CLIF-C OFs, the MELDs, the MELD-Nas, and the CTPs ( P<0.01), while there was no significant difference in AUC between the COSSH ACLF IIs and the CLIF-C ACLFs ( Z=1.696, P=0.090). The cumulative 28-day mortality rates significantly increased with the ascending of COSSH ACLF grade and risk strata of the COSSH ACLF IIs (11.7%, 43.5% and 93.3%, P<0.001; 14.2%, 41.0% and 81.3%, P<0.001). The two ACLF grading systems showed a consistency in severity stratification of HBV-ACLF patients (Kappa=0.478, P<0.001). Conclusion:The COSSH ACLF IIs shows an excellent prognostic performance in predicting short-term mortality of HBV-ACLF patients. Using the new risk stratification scale can simplify the severity stratification of HBV-ACLF patients.

Objective:To investigate the risk factors of bone cement leakage and recompression of injured vertebrae after percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF).Methods:A case-control study was performed to analyze the clinical data of 297 patients with single-segment OVCF who underwent PKP in First Affiliated Hospital of Soochow University from January 2017 to January 2021, including 67 males and 230 females; aged 60-92 years [(69.5±8.2)years]. According to the occurrence of bone cement leakage, the patients were divided into leakage group ( n=36) and no leakage group ( n=261). According to the occurrence of recompression of injured vertebrae, the patients were divided into recollapse group ( n=40) and no recollapse group ( n=257). The gender, age, fracture segment, type of fracture, fracture severity, cortical disruption, intravertebral cleft, preoperative and postoperative local kyphosis angle, correction value of local kyphosis angle, bone cement injection volume, bone cement distribution, and postoperative anti-osteoporosis treatment were recorded. Univariate analysis was used to analyze the correlation of those factors with bone cement leakage and recompression of injured vertebrae after PKP, followed by multivariate Logistic regression analysis to identify the independent risk factors. Results:Univariate analysis showed that fracture severity, cortical disruption and bone cement injection volume were related to bone cement leakage ( P<0.05 or 0.01). Gender, age, fracture segment, type of fracture, intravertebral cleft, preoperative and postoperative local kyphosis angle, correction value of local kyphosis angle, bone cement distribution, and postoperative anti-osteoporosis treatment were not related to bone cement leakage (all P>0.05). Univariate analysis showed that intravertebral cleft, bone cement distribution, and postoperative anti-osteoporosis treatment were associated with recompression of injured vertebrae (all P<0.01). Gender, age, fracture segment, type of fracture, fracture severity, cortical disruption, preoperative and postoperative local kyphosis angle, correction value of local kyphosis angle, and bone cement injection volume were not related to recompression of injured vertebrae (all P>0.05). Multivariate Logistic regression analysis showed that severe fracture ( OR=4.23, 95% CI 1.52-11.81, P<0.01), cortical disruption ( OR=3.29,95% CI 1.52-7.13, P<0.01), and bone cement injection volume >8 ml ( OR=2.31,95% CI 1.09-4.92, P<0.05) were significantly related to bone cement leakage. Multivariate Logistic regression analysis showed that intravertebral cleft ( OR=2.10, 95% CI 1.03-4.30, P<0.05), solid type of bone cement distribution ( OR=2.56, 95% CI 1.25-5.27, P<0.05) and no anti-osteoporosis treatment after operation ( OR=3.06, 95% CI 1.46-6.40, P<0.01) were significantly related to recompression of injured vertebrae. Conclusions:For OVCF patients, severe fracture, cortical disruption, and bone cement injection volume>8 ml are independent risk factors for bone cement leakage after PKP. Intravertebral cleft, solid type of bone cement distribution, and no anti-osteoporosis treatment after operation are independent risk factors for recompression of injured vertebrae after PKP.

Objective:To investigate the prognostic value of systemic inflammatory score (SIS) in prognostic assessment of patients with unresectable metastatic colorectal cancer (mCRC).Methods:The clinical data of 130 patients with unresectable mCRC in Affiliated Haikou Hospital of Xiangya Medical College of Central South University from January 2014 to December 2016 were retrospectively analyzed. The relationship between SIS and clinicopathological characteristics of unresectable mCRC patients was also analyzed. The survival analysis was made by using Kaplan-Meier. The risk factors affecting the prognosis of unresectable mCRC patients were analyzed by using Cox regression model to make univariate and multivariate analysis.Results:According to SIS results, patients were divided into 0-score group (40 cases), 1-score group (58 cases), and 2-score group (32 cases). There were no significant differences in different SIS constitution patients stratified by age, gender, primary tumor location, functional status score, tissue type, RAS gene status, number of metastatic organs, peritoneal spread and molecular targeted therapy (all P > 0.05). Kaplan-Meier survival analysis showed that the 5-year overall survival rates of SIS 0-score, 1-score and 2-score group were 37.5%, 19.0%, 6.3%, respectively; and the difference was statistically significant ( χ2 = 3.152, P<0.01). Cox regression survival analysis showed that female, primary tumor location in right side and SIS (scores of 1-2) were independent risk factors for overall survival in patients with unresectable mCRC (all P<0.05). Conclusion:SIS may be an important indicator for prognostic assessment of patients with unresectable mCRC, and patients with high SIS have poor prognosis.

Objective:To investigate the clinical value of shear wave elastography (SWE) in predicting pathological responses to neoadjuvant chemotherapy in breast cancer.Methods:According to the postoperative pathological responses, 56 patients who received neoadjuvant chemotherapy followed by surgical excision in the Fujian Cancer Hospital from August 2019 to September 2020 were divided into responders and non-responders. The relative change rates of tumor maximum diameter(ΔD2, ΔD4) and SWE stiffness (ΔEmax2, ΔEmax4, ΔEmean2, ΔEmean4) were assessed before NAC and after different NAC cycles (t2, t4). Clinical information, including age, T, N stages, ER, PR, HER2, Ki67, and molecular subtype were also considered as the variables. The independent influencing factors of pathological responses after neoadjuvant chemotherapy were obtained by logistic regression analysis and diagnostic test was carried out.Results:There were 23 cases as responders (41.0%, 23/56), and 33 cases as non-responders (58.9%, 33/56). Results of multivariate analysis showed ΔEmax4 and HER2 index were independent influencing factors of pathological responses ( OR=1.11, P<0.001; OR=31.81, P=0.002). Area under curve of the ΔEmax4 (AUC: 0.869, 95% CI: 0.746-0.941) was higher than that of HER2 (AUC: 0.690, 95% CI: 0.545-0.834). The combination of ΔEmax4 and HER2 gave the best prediction of pathological responses (AUC 0.930, 95% CI: 0.829-0.981). the sensitivity, specificity, diagnostic accuracy, postive predictive value, and negative predictive value were 78.26%, 96.97%, 75.23%, 94.73%, and 86.49%, respectively. Conclusions:ΔEmax4 and HER2 are independent predictors of pathological responses after neoadjuvant chemotherapy for breast cancer. Combined ΔEmax4 and HER2 can improve the predictive diagnostic efficacy of pathological responses to chemotherapy for breast cancer.
