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 understand the change in distribution and antimicrobial resistance of bacteria isolated from blood specimens of Hunan Province,and provide for the initial diagnosis and treatment of clinical bloodstream infection(BSI).Methods Data reported from member units of Hunan Province Antimicrobial Resistance Survei-llance System from 2012 to 2021 were collected.Bacterial antimicrobial resistance surveillance method was imple-mented according to the technical scheme of China Antimicrobial Resistance Surveillance System(CARSS).Bacteria from blood specimens and bacterial antimicrobial susceptibility testing results were analyzed by WHONET 5.6 soft-ware and SPSS 27.0 software.Results A total of 207 054 bacterial strains were isolated from blood specimens from member units in Hunan Province Antimicrobial Resistance Surveillance System from 2012 to 2021,including 107 135(51.7％)Gram-positive bacteria and 99 919(48.3％)Gram-negative bacteria.There was no change in the top 6 pathogenic bacteria from 2012 to 2021,with Escherichia coli(n=51 537,24.9％)ranking first,followed by Staphylococcus epidermidis(n=29 115,14.1％),Staphylococcus aureus(n=17 402,8.4％),Klebsiella pneu-moniae(17 325,8.4％),Pseudomonas aeruginosa(n=4 010,1.9％)and Acinetobacter baumannii(n=3 598,1.7％).The detection rate of methicillin-resistant Staphylococcus aureus(MRSA)decreased from 30.3％in 2015 to 20.7％in 2021,while the detection rate of methicillin-resistant coagulase-negative Staphylococcus(MRCNS)showed an upward trend year by year(57.9％-66.8％).No Staphylococcus was found to be resistant to vancomy-cin,linezolid,and teicoplanin.Among Gram-negative bacteria,constituent ratios of Escherichia coli and Klebsiella pneumoniae were 43.9％-53.9％and 14.2％-19.5％,respectively,both showing an upward trend(both P＜0.001).Constituent ratios of Pseudomonas aeruginosa and Acinetobacter baumannii were 3.6％-5.1％and 3.0％-4.5％,respectively,both showing a downward trend year by year(both P＜0.001).From 2012 to 2021,resistance rates of Escherichia coli to imipenem and ertapenem were 1.0％-2.0％and 0.6％-1.1％,respectively;presenting a downward trend(P＜0.001).The resistant rates of Klebsiella pneumoniae to meropenem and ertapenem were 7.4％-13.7％and 4.8％-6.4％,respectively,presenting a downward trend(both P＜0.001).The resistance rates of Pseudomonas aeruginosa and Acinetobacter baumannii to carbapenem antibiotics were 7.1％-15.6％and 34.7％-45.7％,respectively.The trend of resistance to carbapenem antibiotics was relatively stable,but has de-creased compared with 2012-2016.The resistance rates of Escherichia coli to the third-generation cephalosporins from 2012 to 2021 were 41.0％-65.4％,showing a downward trend year by year.Conclusion The constituent ra-tio of Gram-negative bacillus from blood specimens in Hunan Province has been increasing year by year,while the detection rate of carbapenem-resistant Gram-negative bacillus remained relatively stable in the past 5 years,and the detection rate of coagulase-negative Staphylococcus has shown a downward trend.

Objective To investigate changes in the distribution and antimicrobial resistance of bacteria isolated from cerebrospinal fluid(CSF)specimens in Hunan Province,and provide reference for correct clinical diagnosis and rational antimicrobial use.Methods Data reported by member units of Hunan Province Antimicrobial Resistance Surveillance System from 2012 to 2021 were collected according to China Antimicrobial Resistance Surveillance Sys-tem(CARSS)technical scheme.Data of bacteria isolated from CSF specimens and antimicrobial susceptibility tes-ting results were analyzed with WHONET 5.6 and SPSS 20.0 software.Results A total of 11 837 bacterial strains were isolated from CSF specimens from member units of Hunan Province Antimicrobial Resistance Surveillance Sys-tem from 2012 to 2021.The top 5 strains were coagulase-negative Staphylococcus(n=6 397,54.0％),Acineto-bacter baumannii(n=764,6.5％),Staphylococcus aureus(n=606,5.1％),Enterococcus faecium(n=465,3.9％),and Escherichia coli(n=447,3.8％).The detection rates of methicillin-resistant coagulase-negative Staphyloco-ccus(MRCNS)and methicillin-resistant Staphylococcus aureus(MRSA)were 58.9％-66.3％and 34.4％-62.1％,respectively.No Staphylococcus spp.were found to be resistant to vancomycin,linezolid,and teicoplanin.The de-tection rate of Enterococcus faecium was higher than that of Enterococcus faecalis,and the resistance rates of En-terococcus f aecium to penicillin,ampicillin,high concentration streptomycin and levofloxacin were all higher than those of Enterococcus faecalis(all P=0.001).Resistance rate of Streptococcus pneumoniae to penicillin was 85.0％,at a high level.Resistance rate of Escherichia coli to ceftriaxone was＞60％,while resistance rates to enzyme inhibitors and carbapenem antibiotics were low.Resistance rate of Klebsiella pneumoniae to ceftriaxone was＞60％,to en-zyme inhibitors piperacillin/tazobactam and cefoperazone/sulbactam was＞30％,to carbapenem imipenem and me-ropenem was about 30％.Resistance rates of Acinetobacter baumannii to most tested antimicrobial agents were＞60％,to imipenem and meropenem were 59.0％-79.4％,to polymyxin B was low.Conclusion Among the bac-teria isolated from CSF specimens,coagulase-negative Staphylococcus accounts for the largest proportion,and the overall resistance of pathogenic bacteria is relatively serious.Bacterial antimicrobial resistance surveillance is very important for the effective treatment of central nerve system infection.

Objective To investigate the effect of osteoblast-derived exosome(Exo)mediating microRNA(miR)-494 on bone metabolism and bone remodeling balance in osteoporosis(OP)rats and its mechanism.Methods Exosomes was isolated and identified from MC3T3-E1 osteoblast cell line and transferred to Exo by electrical transfer.Forty SD rats were randomly divided into control,model,miR-494 mimic(miR-494),and miR-494 inhibitor group,10 rats in each group.The ovaries were removed to construct the OP model except the control group.After modeling,the miR-494 group and miR-494 inhibitor group received tail vein injections of exosomes containing the corresponding miRNA,at a dose of 3×109 particles.Four weeks later,bone parameters were detected in each group of rats by Micro-CT,serum bone markers were measured by ELISA,pathological changes in bone tissue were observed by HE staining,osteoclast numbers were detected by tartrate-resistant acid phosphatase(TRACP)staining,and the expression levels of bone remodeling-related proteins and toll-like receptor 4(TLR4)pathway-related proteins were determined by Western blotting.Results Typical cup-shaped or round exosomes were successfully isolated with a diameter of about 100 nm from MC3T3-E1 cells,which contained CD63,CD9,tumor susceptibility gene 101(TSG101),heat shock protein 70(HSP70)proteins and can be taken up by MC3T3-E1 cells.Compared with the model group,the bone parameters of the rats in the miR-494 mimic group decreased,serum bone markers bone Gla protein(BGP),TRACP,C-terminal telopeptide of type Ⅰ collagen(CTX-Ⅰ)increased,osteoprotegerin(OPG),procollagen type Ⅰ N-terminal propeptide(PⅠNP)decreased,bone trabeculae structure was disordered,osteoclasts increased,bone morphogenetic protein 2(BMP-2),Runt related transcription factor 2(RUNX2)in bone tissue downregulated,receptor activator of nuclear factor kappa-B ligand(RANKL)upregulated,TLR4,nuclear factor kappa-B p65(NF-κB p65)and myeloid differentiation primary response 88(MyD88)upregulated(all P＜0.05).In contrast,the situation of the miR-494 inhibitor group was opposite,bone parameters and OPG,PⅠNP increased,BGP,TRACP,CTX-Ⅰdecreased,bone structure returned to normal,osteoclasts decreased,BMP-2,RUNX2 in bone tissue upregulated,RANKL downregulated,TLR4,NF-κB p65 and MyD88 downregulated(all P＜0.05).Conclusion The transfer of miRNA-494 by Exo aggravates abnormal bone metabolism in OP rats and inhibits bone remodeling balance,suggesting that the mechanism of action may be related to the regulation of TLR4 pathway.

Objective:To investigate the efficacy and safety of protein A immunoadsorption (PAIA) combined with rituximab (RTX) in highly sensitized patients who underwent haplo-hematopoietic stem cell transplantation (haplo-HSCT) .Methods:The clinical data of 56 highly sensitized patients treated with PAIA and RTX before haplo-HSCT at the First Affiliated Hospital of Soochow University and Soochow Hopes Hematonosis Hospital between March 2021 and June 2023 were retrospectively analyzed. The number of human leukocyte antigen (HLA) antibody types and the mean fluorescence intensity (MFI), humoral immunity, adverse reactions during adsorption, and survival within 100 days before and after adsorption were measured.Results:After receiving the PAIA treatment, the median MFI of patients containing only HLA Ⅰ antibodies decreased from 7 859 (3 209-12 444) to 3 719 (0-8 275) ( P<0.001), and the median MFI of HLA Ⅰ+Ⅱ antibodies decreased from 5 476 (1 977-12 382) to 3 714 (0-11 074) ( P=0.035). The median MFI of patients with positive anti-donor-specific antibodies decreased from 8 779 (2 697-18 659) to 4 524 (0–15 989) ( P<0.001). The number of HLA-A, B, C, DR, and DQ antibodies in all patients decreased after the PAIA treatment, and the differences were statistically significant (A, B, C, DR: P<0.001, DQ: P<0.01). The humoral immune monitoring before and after the PAIA treatment showed a significant decrease in the number of IgG and complement C3 ( P<0.001 and P=0.002, respectively). Forty-four patients underwent HLA antibody monitoring after transplantation, and the overall MFI and number of antibody types decreased. However, five patients developed new antibodies with low MFI, and nine patients continued to have high MFI. The overall survival, disease-free survival, non-recurrent mortality, and cumulative recurrence rates at 100 days post-transplantation were 83.8%, 80.2%, 16.1%, and 4.5%, respectively. Conclusions:The combination of PAIA and RTX has a certain therapeutic effect and good safety in the desensitization treatment of highly sensitive patients before haplo-HSCT.

Bibliometric and scientific knowledge graph methods were used to analyze the research status and hot spots of acupuncture-moxibustion in treatment of myofascial pain syndrome (MPS) and explore its development trend. The articles of both Chinese and English versions relevant to MPS treated by acupuncture-moxibustion were searched in CNKI, VIP, Wanfang, SinoMed and WOS from the database inception to March 20, 2023. Using Excel2016, CiteSpace6.2.R2 and VOSviewer1.6.18, the visual analysis was conducted by means of the cooperative network, keyword co-occurrence, keyword timeline, keyword emergence, etc. From Chinese databases and WOS database, 910 Chinese articles and 300 English articles were included, respectively. The annual publication volume showed an overall rising trend. Literature output of English articles was concentrated in Spain, China, and the United States, of which, there was less cross-regional cooperation. In the keyword analysis, regarding acupuncture-moxibustion therapy, Chinese articles focused on "acupuncture", "electroacupuncture" and "acupotomy"; while, "dry needling" and "injection" were dominated for English one. Clinical study was the current hot spot in Chinese databases, in comparison, the randomized controlled double-blind clinical trial was predominant in WOS. Both Chinese and English articles were limited in the report of mechanism research. The cooperation among research teams should be strengthened to conduct comparative research, dose-effect research and effect mechanism research with different methods of acupuncture-moxibustion involved so that the evidences can be provided for deeper exploration.

Objective:To evaluate the efficacy and safety of vedolizumab (VDZ) in the treatment of active ulcerative colitis (UC).Methods:From November 1, 2020 to October 30, 2022, at the Department of Gastroenterology, the Sixth Affiliated Hospital of Sun Yat-sen University, 81 UC patients who received VDZ treatment and completed a 14-week follow-up were retrospectively selected. The clinical data of patients, including age, disease duration, disease activity of UC were collected. The VDZ efficacy evaluation included primary and secondary efficacy indicators. The primary efficacy indicator was the clinical remission rate after 14 weeks of VDZ treatment, and the secondary efficacy indicators included the clinical response rate, steroids-free remission rate, endoscopic remission rate after 14 weeks of treatment as well as the clinical response rate, clinical remission rate, steroids-free remission rate, secondary loss of response rate after 52 weeks of treatment. The adverse reactions during the treatment were recored. Taking clinical remission after 14 weeks of treatment as the dependent variable, univariate analysis was performed to identify the risk factors affecting clinical remission of VDZ. Binary logistic regression analysis was used for multivariate analysis to determine the independent risk factors of VDZ-included clinical remission. Chi-square test and Wilcoxon signed-rank test were used for statistical analysis.Results:Among the 81 UC patients, the age was 40.0 years old (29.0 years old, 53.5 years old) and the disease duration was 42.5 months (22.5 months, 94.7 months). The proportion of patients with mild active UC was 21.0% (17/81), the proportion of patients with moderate active UC was 64.2% (52/81), and the proportion of patients with severe active UC was 14.8% (12/81). After 14 weeks of treatment, the total Mayo score decreased from baseline level of 7.0 (6.0, 9.0) to 1.0 (0.0, 3.0), and the difference was statistically significant ( Z=-6.87, P<0.001). The clinical response rate was 84.0% (68/81) and the clinical remission rate was 69.1% (56/81) after 14 weeks of treatment. Of the 17 patients treated with combination of corticosteroid therapy, 10 achieved steroid-free remission, and the endoscopic remission rate was 34.8% (23/66). Of the 43 patients followed up to 52 weeks, the total Mayo score of UC patients decreased from baseline level of 7.0 (6.0, 9.0) to 0.0 (0.0, 1.0) after 52 weeks of treatment, and the difference was statistically significant ( Z=-3.25, P<0.001). The clinical response rate was 69.8% (30/43), and the clinical remission rate was 65.1% (28/43). Of the 13 patients treated with combination of corticosteroid therapy, 10 patients achieved steroid-free remission. The secondary loss of response rate was 15.2%(5/33) .The result of the univariate analysis showed that previous use of glucocorticoids was a risk factor of clinical remission after 14 weeks of VDZ treatment ( χ2=5.88, P=0.015). The result of multivariate logistic regression analysis showed that previous use of glucocorticoids was an independent risk factor of clinical remission after 14 weeks of VDZ treatment ( OR=3.429, 95% confidence interval 1.235 to 9.517, P=0.014). During the follow-up period, 12.3% (10/81) of patients developed Clostridium difficile infections, except for 1 case stopped VDZ treatment because the clinical response was not reached, remaining 9 cases continued VDZ treatment after received anti- Clostridium difficile treatment. Conclusion:VDZ has good clinical efficacy and safety in the treatment of Chinese UC patients, and patients with no history of glucocorticoid use may be more likely to achieve clinical remission after 14 weeks of treatment.

Stenotrophomonas species are non-fermentative Gram-negative bacteria that are widely distributed in environment and are highly resistant to numerous antibiotics. Thus, Stenotrophomonas serves as a reservoir of genes encoding antimicrobial resistance (AMR). The detection rate of Stenotrophomonas is rapidly increasing alongside their strengthening intrinsic ability to tolerate a variety of clinical antibiotics. This review illustrated the current genomics advances of antibiotic resistant Stenotrophomonas, highlighting the importance of precise identification and sequence editing. In addition, AMR diversity and transferability have been assessed by the developed bioinformatics tools. However, the working models of AMR in Stenotrophomonas are cryptic and urgently required to be determined. Comparative genomics is envisioned to facilitate the prevention and control of AMR, as well as to gain insights into bacterial adaptability and drug development.
