BACKGROUND: Current replacement procedures for stenosis or occluded arteries using prosthetic grafts have serious limitations in clinical applications, particularly, endothelialization of the luminal surface is a long-standing unresolved problem.METHOD: We produced a cell-based hybrid vascular graft using a bioink engulfing adipose-derived mesenchymal stromal cells (ADSCs) and a 3D bioprinting process lining the ADSCs on the luminal surface of GORE-Tex grafts. The hybrid graft was implanted as an interposition conduit to replace a 3-cm-long segment of the infrarenal abdominal aorta in Rhesus monkeys. RESULTS: Complete endothelium layer and smooth muscle layer were fully developed within 21 days post-implantation, along with normalized collagen deposition and crosslinking in the regenerated vasculature in all monkeys. The regenerated blood vessels showed normal functionality for the longest observation of more than 1650 days. The same procedure was also conducted in miniature pigs for the interposition replacement of a 10-cm-long right iliac artery and showed the same long-term effective and safe outcome. CONCLUSION This cell-based vascular graft is ready to undergo clinical trials for human patients.

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 identify meaningful objective examination methods by analyzing the results of vari-ous objective examinations of children with recurrent vertigo(RVC).Methods Fifty children with RVC(29 in ver-tigo attacking group,21 in vertigo non-attacking group)and 20 children without RVC were selected.All partici-pants underwent a series of relevant objective examinations,the results of each examination were statistically ana-lyzed and the characteristic differences of each examination between the RVC group and the control group were ob-tained.Results ① The abnormal rate of sleep SpO2,high stimulation rate ABR and AHI in the RVC group were significantly higher than those in the control group(P＜0.05).② The abnormal rate of sleep SpO2 and high stimu-lation rate ABR in the vertigo attacking group were higher than those in the vertigo non-attacking group.There was a statistical difference between the two groups(P＜0.05).③ Pure tone audiometry(or conditioned play audiome-try),acoustic immittance,cranial MRI,positional test and vHIT were normal in both RVC group and normal con-trol group.Conclusion Continuous sleep SpO2 and high stimulation rate ABR are correlated with RVC,especially RVC during vertigo attacking.AHI is correlated with RVC,but not with the onset of vertigo.Clinically,continu-ous sleep SpO2 monitoring,PSG and high stimulation rate ABR can be used as auxiliary examinations for the diagno-sis of RVC.

Objective To explore the value of deep learning models in predicting axillary lymph node(ALN)metastasis of breast cancer based on intratumoral and peritumoral dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI).Methods A retrospective analysis was conducted on cases from Tianjin Medical University Cancer Hospital and Laoshan Branch of Affiliated Hospital of Qingdao University,involving a total of 850 lesions in 850 patients.The region of interest within the tumor was delineated at the largest area of the lesion on the first enhancement images and automatically expanded by 3 mm and 6 mm in a conformal fashion.Deep learning prediction models based on ResNet50 were developed via intratumoral,peritumoral,and intratumoral combined peritumoral models,respectively,and a comprehensive prediction model was developed by integrating semantic features of imaging reports.Cases from Tianjin Medical University Cancer Hospital were randomly divided into training and test cohorts in a 7∶3 ratio,while cases from Laoshan Branch of Affiliated Hospital of Qingdao University served as the external validation cohort.The area under the curve(AUC),accuracy,sensitivity,specificity,F1-score,and Brier-score were calculated,respectively.Results The model incorporating intratumoral,peritumoral(3 mm),and semantic features demonstrated the highest performance,with AUC of 0.801[95％confidence interval(CI)0.765-0.845],0.781(95％CI 0.745-0.817),and 0.752(95％CI 0.700-0.793)in the training cohort,test cohort,and external validation cohort,respectively,and there was no significant difference in AUC between combined model and intratumoral/peritumoral model,respectively,but it demonstrated the higher sensitivity and F1-score,and the lower Brier-score.Conclusion Incorporating peritumoral images into the conventional model based on intratumoral images enhanced the predictive ability of ALN metastasis in breast cancer.

Objective:To investigate the current status of methotrexate(MTX)application in rheuma-toid arthritis(RA)patients.Methods:The clinical and laboratory data of RA patients who attended in the Department of Rheumatology and Immunology of Peking University Third Hospital from January 1,2022 to November 31,2023 were collected retrospectively.In order to figure out the relationship between MTX use and RA disease control,we recorded information including the starting dose,maximum dose,current dose,reasons of discontinuation of MTX,etc.The t test,Mann-Whitney U test,Chi-square test,Fisher's exact probability and multivariable Logistic regression were used for analysis.Results:A total of 239 RA patients were enrolled,including 201 females and 38 males with a mean age of(54.5±14.3)years.Among them,101 patients reached the therapeutic target[clinical remission or low disease activity assessed by 28-joint disease activity score(DAS28)-erythrocyte sedimentation rate(ESR)],accounting for 42.2％of the RA patients.Twenty-six patients met the European League Against Rheumatism(EU-LAR)definition of difficult-to-treat(D2T)RA,accounting for 10.9％of RA patients.The proportion of the RA patients who had ever used MTX was 84.1％,and those who were currently on it accounted for only 39.7％.The MTX dose was generally low,with a starting dose of(9.5±3.0)mg/week,the maxi-mum dose of 15.0(10.0,15.0)mg/week,and the current dose being(12.4±2.7)mg/week.The most common reasons for MTX dose reduction or discontinuation were adverse reactions,mainly including abnormalities of hepatic function,gastrointestinal discomfort,leucopenia,etc.Those who were currently on MTX had a higher rate of treatment to target(52.6％vs.35.4％,P＞0.05),lower disease activity score(DAS28-ESR,3.6±1.8 vs.4.2±1.8,P＜0.05),and fewer tender joint counts(4.8±8.3 vs.8.6±10.4,P＜0.05)as compared with those who were not taking the drug,while swollen joint count,pain visual analog score and patient's global score,C-reactive protein(CRP)level and ESR level were not significantly different between the two groups.Compared with those who did not reach the target of treatment,those who did had a higher rate of curr-ent MTX application(48.5％vs.33.3％,P＜0.05),but the history of MTX did not differ between the two groups(84.2％vs.84.1％,P＞0.05).The maximum dose of MTX(median 15.0 mg/week vs.13.7 mg/week,P＞0.05)and the current dose[(12.9±2.5)mg/week vs.(11.8±2.8)mg/week,P＞0.05]was higher in those who achieved the target,while the starting dose[(9.6±2.8)mg/week vs.(9.5±3.1)mg/week,P＞0.05]and the rate of prior MTX(84.2％vs.83.3％,P＞0.05)was comparable between the two groups.The D2T RA patients had a higher rate of previous MTX use(96.2％vs.82.6％,P＜0.05)and a higher starting dose[(11.6±4.3)mg/week vs.(9.8±2.7)mg/week,P＞0.05],while the maximum dose(median 12.5 mg/week vs.15.0 mg/week,P＞0.05)and the current dose were both lower[(11.6±3.2)mg/week vs.(12.5±2.6)mg/week,P＞0.05]than the non-D2T RA patients.Conclusion:The proportion of regular use of MTX among RA patients was low and the dose was generally small.The RA patients with regular use of MTX had a higher rate of achieving treatment target and lower disease ac-tivity.Those who achieved the target had a higher rate of current MTX use,higher maximum and current doses than those who did not.The D2T RA patients had lower maximum and current doses of MTX than the non-D2T RA patients.Therefore,increasing the usage and dosage of MTX in RA patients may help to improve the rate of achieving treatment targets.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.
