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: The docking and superantigen activity sites of staphylococcal enterotoxin-like W (SElW) and T cell receptor (TCR) were predicted, and its SElW was cloned, expressed and purified. Methods: AlphaFold was used to predict the 3D structure of SElW protein monomers, and the protein models were evaluated with the help of the SAVES online server from ERRAT, Ramachandran plot, and Verify_3D. The ZDOCK server simulates the docking conformation of SElW and TCR, and the amino acid sequences of SElW and other serotype enterotoxins were aligned. The primers were designed to amplify selw, and the fragment was recombined into the pMD18-T vector and sequenced. Then recombinant plasmid pMD18-T was digested with BamHⅠand Hind Ⅲ. The target fragment was recombined into the expression plasmid pET-28a(+). After identification of the recombinant plasmid, the protein expression was induced by isopropyl-beta-D- thiogalactopyranoside. The SElW expressed in the supernatant was purified by affinity chromatography and quantified by the BCA method. Results: The predicted three-dimensional structure showed that the SElW protein was composed of two domains, the amino-terminal and the carboxy-terminal. The amino-terminal domain was composed of 3 α-helices and 6 β-sheets, and the carboxy-terminal domain included 2 α-helices and 7 antiparallel β-sheets composition. The overall quality factor score of the SElW protein model was 98.08, with 93.24% of the amino acids having a Verify_3D score ≥0.2 and no amino acids located in disallowed regions. The docking conformation with the highest score (1 521.328) was selected as the analysis object, and the 19 hydrogen bonds between the corresponding amino acid residues of SElW and TCR were analyzed by PyMOL. Combined with sequence alignment and the published data, this study predicted and found five important superantigen active sites, namely Y18, N19, W55, C88, and C98. The highly purified soluble recombinant protein SElW was obtained with cloning, expression, and protein purification. Conclusions: The study found five superantigen active sites in SElW protein that need special attention and successfully constructed and expressed the SElW protein, which laid the foundation for further exploration of the immune recognition mechanism of SElW.

Objective:To investigate the safety and feasibility of the CHESS endoscpic ruler (CHESS ruler), and the consistency between the measured values and the interpretation values by endoscopic physician experience.Methods:From January 2021 to January 2022, a total of 105 liver cirrhosis patients with portal hypertension were prospectively enrolled from General Hospital, Xixia Branch Hospital, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region (29 cases), and the First People′s Hospital of Yinchuan (25 cases), General Hospital of Ningxia Medical University (18 cases), Wuzhong People′s Hospital (10 cases), the Fifth People′s Hospital of Ningxia Hui Autonomous Region (10 cases), Shizuishan Second People′s Hospital (6 cases), Yinchuan Second People′s Hospital (5 cases), and Zhongwei People′s Hospital (2 cases) 8 hospitals. The clinical characteristics of all the patients, including gender, age, nationality, etiolog of liver cirrhosis, and Child-Pugh classification of liver function were recorded. A big gastroesophageal varices was defined as diameter of varices ≥5 mm. Endoscopist (associated chief physician) performed gastroscopy according to the routine gastroscopy procedures, and the diameter of the biggest esophageal varices was measured by experience and images were collected, and then objective measurement was with the CHESS ruler and images were collected. The diameter of esophageal varices of 10 randomly selected patients (random number table method) was determined by 6 endoscopists (attending physician or associated chief physician) with experience or measured by CHESS ruler. Kappa test was used to test the consistency in the diameter of esophageal varices between measured values by CHESS ruler and the interpretation values by endoscopic physician experience.Results:Among 105 liver cirrhosis patients with portal hypertension, male 65 cases and female 40 cases, aged (54.8±12.2) years old, Han nationality 82 cases, Hui nationality 21 cases and Mongolian nationality 2 cases. The etiology of liver cirrhosis included chronic hepatitis B (79 cases), alcoholic liver disease (7 cases), autoimmune hepatitis (7 cases), chronic hepatitis C (2 cases), and other etiology (10 cases). Liver function of 32 cases was Child-Pugh A, Child-Pugh B 57 cases, and Child-Pugh C 16 cases. All 105 liver cirrhosis patients with cirrhotic portal hypertension were successfully measured the diameter of gastroesophageal varices by CHESS ruler, and the success rate of application of CHESS ruler was 100.0% (105/105). The procedure time from the CHESS ruler into the body to the exit of the body after measurement was (3.50±2.55) min. No complications happened in all the patients during measurement. Among 105 liver cirrhosis patients with cirrhotic portal hypertension, 96 cases (91.4%) were recognized as big gastroesophageal varices by the endoscopists. Totally 93 cases (88.6%) were considered as big gastroesophageal varices by CHESS ruler. Eight cases were recognized as big gastroesophageal varices by the endoscopist, however not by the CHESS ruler; 5 cases were recognized as big gastroesophageal varices by the CHESS ruler, but not by the endoscopists; 4 cases were not recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler; 88 cases were recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler. The missed diagnostic rate of big gastroesophageal varices by the endoscopists experience was 5.4% (5/93), and the Kappa value of consistency coefficient between the measurement by the CHESS ruler and the interpretation by endoscopists experience was 0.31 (95% confidence interval 0.03 to 0.60). The overall Kappa value of consistency coefficient by 6 endoscopists measured by CHESS ruler in big gastroesophageal varices diagnosis was 0.77 (95% confidence interval 0.61 to 0.93).Conclusion:As an objective measurement tool, CHESS ruler can make up for the deficiency of subjective judgment by endoscopists, accurately measure the diameter of gastroesophageal varices, and is highly feasible and safe.

Objective: To investigate the clinical features and long-term prognosis of primary biliary cholangitis (PBC) in patients with past hepatitis B virus (HBV) infection. Methods: 353 cases with PBC who visited the Liver Disease Center of Beijing Friendship Hospital Affiliated to Capital Medical University between January 2000 and January 2018 were retrospectively analyzed and were divided into the past HBV infection group (156 cases) and the no HBV infection group (197 cases). The two groups' baseline clinical features were compared. Ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, and long-term liver transplantation-free survival rate were compared through outpatient and telephone follow-up. Results: PBC with past HBV infection had a significantly reduced female proportion compared to the no HBV infection group (91.9% vs. 79.5%, P = 0.001). However, there were no statistically significant differences in age, biochemical indices, immunological indicators, platelet count, cirrhosis proportion, and others. Ursodeoxycholic acid biochemical response rate was reduced in patients with past HBV infection at the end of one year of treatment, but the difference was not statistically significant (65.8% vs. 78.2%, P = 0.068). In addition, there were no statistically significant differences between the GLOBE score (0.57 vs. 0.59, P = 0.26) and UK-PBC 5-year (2.87% vs. 2.87%, P = 0.38), 10-year (9.29% vs. 8.2%, P = 0.39) and 15-year liver transplantation rates (16.6% vs. 14.73%, P = 0.39). Lastly, the overall 5-year liver transplantation-free survival rate had no statistically significant difference between the two groups of patients (86.4% vs. 87.5%, P = 0.796). Conclusion: Primary biliary cholangitis had no discernible effect in terms of age at onset, biochemical indices, immunological indicators, cirrhosis proportion, ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, or overall liver transplantation-free survival rate in patients with past hepatitis B virus infections.

BackgroundThe schizophrenia is majorly treated with drug and through physical therapy. However， both treatments would lead to adverse reactions， which could affect therapy adherence and treatment efficacy. Previous studies have shown that aerobic exercise can help alleviate cognitive function in patients with Alzheimer's disease and depressive disorder. At present， little research has been done on such alleviation in schizophrenia patients. ObjectiveTo explore the effect of aerobic exercise on cognitive function in male patients with chronic schizophrenia， so as to provide references for relevant treatments. MethodsA total of 76 male patients with chronic schizophrenia hospitalized in the Fourth People's Hospital of Wuhu between December 2022 and April 2023 were selected as the study subjects and， in accordance with random number table， divided into study group （n=36） and control group （n=40）. Both groups received conventional drug treatment. On this basis， the study group received a 60-minute aerobic exercise 5 times a week for 8 weeks as intervention. Before and after intervention， assessment of cognitive function was performed by using MATRICS Consensus Cognitive Battery （MCCB） and Stroop Color Word Test （SCWT）. ResultAfter intervention， compared with the control group， the study group spent less time on finishing the Trail Making Test and scored higher in both the spatial span test and maze test （Z=-2.070， -2.306， -2.375， P<0.05）. Repeated measure ANOVA results showed that the time main effect of Hopkins Verbal Learning Test score was statistically significant in the two groups after intervention （F=39.067， P<0.05）. So was the interaction effect between the time and group of the Brief Visuospatial Memory Test and Verbal Fluency Test scores （F=10.092， 9.252， P<0.05）. After intervention， the scores of the Brief Visuospatial Memory Test and Verbal Fluency Test in the study group were higher than those in the control group （t=6.689， 4.249， P<0.05）. As for the study group itself， the scores were higher than those before intervention （t=23.746， 23.842， P<0.05）. After intervention， the numbers of correct reading in color test and word test in the study group were more than those in the control group （Z=-2.358， -2.771， P<0.05）. The interaction effect between the time and group of the reaction time in color test， word test and color word interference test were statistically significant in both groups （F=23.383， 19.888， 19.662， P<0.05）. After intervention， the reaction time in color test and color word interference test of the study group was shorter than those of the control group （t=4.895， 6.163， P<0.05）. As for the study group itself， the reaction time were shorter than before intervention （t=54.318， 42.425， 42.141， P<0.01）. ConclusionAerobic exercise may help alleviate the cognitive problems in male patients with chronic schizophrenia in terms of information processing speed， working memory， reasoning/problem solving ability， word learning and memorizing， visual learning and memorizing， and executive function. ［Funded by Wuhu Science and Technology Plan Project （number， 2021jc2-3）］

OBJECTIVE: To investigate whether electroacupuncture (EA) alleviates cognitive impairment by suppressing the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88) signaling pathway, which triggers immune-inflammatory responses in the hippocampus of rats with vascular dementia (VaD). METHODS: The experiments were conducted in 3 parts and in total the Sprague-Dawley rats were randomly divided into 8 groups by a random number table, including sham, four-vessel occlusion (4-VO), 4-VO+EA, 4-VO+non-EA, sham+EA, 4-VO+lipopolysaccharide (LPS), 4-VO+LPS+EA, and 4-VO+TAK-242 groups. The VaD model was established by the 4-VO method. Seven days later, rats were treated with EA at 5 acupoints of Baihui (DV 20), Danzhong (RN 17), Geshu (BL 17), Qihai (RN 6) and Sanyinjiao (SP 6), once per day for 3 consecutive weeks. Lymphocyte subsets, lymphocyte transformation rates, and inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor α(TNF-α) were measured to assess immune function and inflammation in VaD rats. Transmission electron microscopy was used to observe the ultrastructure of nerve cells in the hippocampus. The levels of TLR4, MyD88, IL-6, and TNF-α were detected after EA treatment. TLR4/MyD88 signaling and cognitive function were also assessed after intracerebroventricular injection of TLR4 antagonist TAK-242 or TLR4 agonist LPS with or without EA. RESULTS: Compared with the 4-VO group, EA notably improved immune function of rats in the 4-VO+EA group, inhibited the protein and mRNA expressions of TLR4 and MyD88 in the hippocampus of rats, reduced the expressions of serum IL-6 and TNF-α (all P<0.05 or P<0.01), and led to neuronal repair in the hippocampus. There were no significant differences between the 4-VO+LPS+EA and 4-VO+EA groups, nor between the 4-VO+TAK-242 and 4-VO+EA groups (P>0.05). CONCLUSIONS EA attenuated cognitive impairment associated with immune inflammation by inhibition of the TLR4/MyD88 signaling pathway. Thus, EA may be a promising alternative therapy for the treatment of VaD.

OBJECTIVE: To investigate and compare the clinical efficacies of remnant-preserving and remnant-non-preserving, remnant-non-preserving remnant segment preserving and remnant root preserving with anterior cruciate ligament reconstruction. METHODS: From March 2014 to December 2017, 204 patients with anterior cruciate ligament (ACL) injuries were treated by single-bundle ACL reconstruction with hamstring tendon autograft. According to the different methods of remnant preservation, the procedures were divided into remnant segment preserving group (A), remnant root preserving group (B), and remnant-non-preserving group (C). There were 37 males and 39 femalesin group A aged from 16 to 43 years old with an average of (28.80±5.41) years old. The time from injury to operation ranged from 2 to 11 weeks with an average of (3.68±1.04) weeks. In group B, there were 39 males and 25 females aged from 18 to 41 years old with an average of (28.42±5.60) years old. The time from injury to operation ranged from 2 to 10 weeks with an average of (3.36±1.68) weeks. In group C, there were 37 males and 27 females aged from 18 to 43 years old with an average of (29.10±6.11) years old. The time from injury to operation ranged from 3 to 11 weeks with an average of (3.54±1.46) weeks. The range of motion (ROM) of the knee was used to assess the range of extension and flextion of the knee at pre-operation and 24 months after operation. Lysholm score and the international knee documentation committee (IKDC) score were used to assess the knee function. The differences among three procedures were judged by comparing among the three groups at 6, 12 and 24 months postoperatively. RESULTS: All incisions got a one stage healing, and no complications, such as vascular injury, nerve damage and articular infect or the like, occurred. All the patients were followed up, and the follow-up duration of group A ranged from 24.00 to 45.96 months with a mean of (35.52±14.40) months;the follow up duration of group B ranged from 27.96 to 48.00 months with a mean of (37.56±10.68) month;and the follow up duration of group C ranged from 24.00 to 66.00 months with a mean of (37.08±13.44) month. There were no significant differences in follow up time among three groups ( CONCLUSION Compared with remnant-non-preserving group, the residual tissue of anterior cruciate ligament is preserved, which is conducive to promote the healing and remodeling of tendon graft and accelerate the recovery of joint function. Proper fixation of residual tissue and restoration of its tension are the key factors affecting the postoperative efficacy.

To evaluate whether the polygenic profile modifies the development of sporadic Alzheimer's disease (sAD) and pathological biomarkers in cerebrospinal fluid (CSF), 462 sAD patients and 463 age-matched cognitively normal (CN) controls were genotyped for 35 single-nucleotide polymorphisms (SNPs) that are significantly associated with sAD. Then, the alleles found to be associated with sAD were used to build polygenic risk score (PRS) models to represent the genetic risk. Receiver operating characteristic (ROC) analyses and the Cox proportional hazards model were used to evaluate the predictive value of PRS for the sAD risk and age at onset. We measured the CSF levels of Aβ42, Aβ42/Aβ40, total tau (T-tau), and phosphorylated tau (P-tau) in a subgroup (60 sAD and 200 CN participants), and analyzed their relationships with the PRSs. We found that 14 SNPs, including SNPs in the APOE, BIN1, CD33, EPHA1, SORL1, and TOMM40 genes, were associated with sAD risk in our cohort. The PRS models built with these SNPs showed potential for discriminating sAD patients from CN controls, and were able to predict the incidence rate of sAD and age at onset. Furthermore, the PRSs were correlated with the CSF levels of Aβ42, Aβ42/Aβ40, T-tau, and P-tau. Our study suggests that PRS models hold promise for assessing the genetic risk and development of AD. As genetic risk profiles vary among populations, large-scale genome-wide sequencing studies are urgently needed to identify the genetic risk loci of sAD in Chinese populations to build accurate PRS models for clinical practice.

OBJECTIVE: To investigate the prenatal ultrasonographic manifestations of fetal congenital omphalo-enteric fistula with intestinal prolapse and improve the understanding and diagnosis of this disease.METHODS: A retrospective analysis of the prenatal ultrasonographic features was performed in 2 cases of fetal congenital omphalo-enteric fistula with intestinal prolapse comnfirmed after surgery between July 2016 and September 2017 in First Affiliated Hospital of Fujian Medical University,and the ultrasonographic manifestations were compared with postnatal looks and intraoperative conditions.Characteristics of prenatal ultrasonographic manifestations were summarized.RESULTS: Both cases were misdiagnosed as omphalocele by prenatal ultrasonography.Congenital omphalo-enteric fistula with intestinal prolapse was verified by surgery after delivery.A narrow pedicle,special bowel-shape and incomplete capsule were its prenatal ultrasonic characteristics.CONCLUSION: Fetal congenital omphalo-enteric fistula with intestinal prolapse is rare,but has particular prenatal ultrasonographic manifestations. Strengthening the understanding of the disease,reducing misdiagnosis and improving prenatal ultrasound diagnosis will provide help for prenatal counseling and clinical choice for time of delivery.
