OBJECTIVE: To evaluate the differential expression of RNA in blood monocytes in patients with Juvenile idiopathic arthritis (JIA) treated with TNF antagonists (TNFi), and to explore the effect and mechanism of gene expression on the efficacy of JIA. METHODS: A total of 29 children with JIA treated with methotrexate (MTX) and TNFi in Guangzhou Women and Children's Medical Center of Guangzhou Medical University from April 2021 to November 2023 were enrolled. After 6 months, the children were divided into two groups according to the treatment effect, i.e., 13 cases in the ineffective group and 16 cases in the effective group, the peripheral blood of the children was collected, the blood mononuclear cells were isolated for transcriptome sequencing, the differentially expressed genes between the groups were analyzed, the signaling pathways and metabolic pathways related to the efficacy of TNFi were analyzed by GO and KEGG enrichment, and the mechanism related to the efficacy of TNFi was explored. This study was approved by Medical Ethics Committee of the Guangzhou Women and Children's Medical Center of Guangzhou Medical University (Ethics No.: 2023-330B00). RESULTS: There was a statistically significant difference in the gender and age distribution between the two groups of children (P < 0.05), while no statistically significant differences were observed in disease duration, rheumatoid antibody levels, or JIA subtypes (P > 0.05). After sequencing data quality control and comparison of reference genomes, a total of 18 523 protein-coding genes were identified in all children's samples. A total of 705 differentially expressed genes (DEGs) were identified between the effective group and the invalid group through differential analysis, of which 579 were up-regulated in the effective group and 126 in the inactive group. GO function and KEGG pathway enrichment analysis showed that DEG was significantly enriched in 55 GO entries and 32 KEGG metabolic pathways, which were mainly related to IL-1β production and regulation, cytokine production and regulation, cytokine-cytokine receptor interaction, immune response regulation, and Toll-like receptor signaling pathway. CONCLUSION DEG between the effective and ineffective groups of TNFi treatment may be involved in the biological processes such as cytokine production and regulation, cytokine-receptor interaction, and immune response regulation, which will be helpful to predict the efficacy and prognosis of TNFi treatment for JIA.

Objective To longitudinally analyze the changes in perioperative nutritional indicators in elderly patients with spontaneous intracerebral hemorrhage(ICH)and their correlation with the score of modified Rankin scale(mRS)score.Methods A total of 295 elderly ICH patients ad-mitted to the neurosurgery intensive care unit of North China University of Science and Technolo-gy Affiliated Hospital from June 2022 to November 2024 were consecutively enrolled in this study.The levels of relevant nutritional indicators were measured before(T1),and in 1(T2),3(T3),5(T4)and 7 d(T5)after surgery.According to the mRS score in 90 d after onset of the disease,they were divided into a good prognosis group(mRS score≤ 2,114 cases)and a poor prognosis group(mRS score≥3,181 cases).The general data and levels of nutritional indicators at above time points were compared between the two groups.Binary logistic regression analysis was applied to study the relationship between the perioperative nutritional indicator levels and the prognosis in elderly patients with spontaneous ICH.Results The poor prognosis group had significantly higher SBP,larger proportions of stroke history,hemorrhage in the brainstem and midline dis-placement,and increased NIHSS score than the good prognosis group(P＜0.05,P＜0.01).Obvi-ously lower BMI(56.48±9.54 kg vs 66.62±8.12 kg),decreased serum levels of albumin[40.24(39.10,41.16)g/L vs 43.30(40.65,45.50)g/L],prealbumin[203.00(164.00,261.00)mg/L vs 229.00(180.00,282.00)mg/L]and TC[4.68(4.11,5.39)mmol/L vs 4.91(4.47,5.66)mmol/L],reduced lymphocyte count[1.58(0.95,2.03)× 109/L vs 1.77(1.99,1.91)× 109/L],and reduced GCS[7.00(5.00,10.00)vs 9.00(7.00,13.00)]and Barthel[55.00(43.00,64.00)vs 61.00(52.00,69.00)]scores at admission were observed in the poor prognosis group than the good prognosis group(all P＜0.01).At all different time points,the poor prognosis group also got notably higher Controlling Nutritional Status(CONUT)scores(reaching the highest levels at 3 d after opera-tion),and lower Prognostic Nutritional Index(PNI)score and Geriatric Nutritional Risk Index(GNRI)score(both declining the lowest levels at same time)when compared with the poor prog-nosis group(all P＜0.01).Binary logistic regression analysis showed that COUNT scores,PNI scores and GNRI scores before(T1)and at 1(T2),3(T3),5(T4)and 7 d(T5)after operation were independent risk factors for 90-day poor prognosis in elderly patients with spontaneous ICH.Conclusion The fluctuations of 3 nutritional indicators at different time points in the periopera-tive period are closely associated with the 90-day prognosis of elderly ICH patients.Monitoring the changes in the nutritional indicators can quickly and conveniently predict the prognosis of the pa-tients,which has high clinical application value.

Objective:To explore the short-term outcomes of 3D-printing stand-alone artificial vertebral body(AVB)in the surgical procedure of anterior cervical corpectomy and fusion(ACCF).Methods:Following the proposal of IDEAL(idea,development,exploration,assessment,and long-term follow-up)framework,we designed and conducted this single-armed,retrospective cohort study.The patients with cervical spondylotic myelopathy were recruited,and these patients exclusively received the surgical procedure of single-level ACCF in our single center.After the process of corpectomy,the size was tailored using different trials and the most suitable stand-alone AVB was then implanted.This AVB was manufactured by the fashion of 3D-printing.Two pairs of screws were inserted in an inclined way into the adjacent vertebral bodies,to stabilize the AVB.The participants were regularly followed-up after the operation.Their clinical data were thoroughly reviewed.We assessed the neurological status according to Japanese Orthopedic Association(JOA)scale.We determined the fusion based on imaging examination six months after the operation.The recorded clinical data were analyzed using specific software and they presented in suitable styles.Paired t test was employed in comparison analysis.Results:In total,there were eleven patients being recruited eventually.The patients were all followed up over six months after the operation.The mean age of the cohort was(57.2±10.2)years.The mean operation time was(76.1±23.1)min and the median bleeding volume was 150(100,200)mL.The postoperative course was uneventful for all the cases.Dysphagia,emergent hematoma,and deterioration of neurological func-tion did not occur.Mean JOA scores were 13.2±2.2 before the operation and 16.3±0.8 at the final follow-up,which were significantly different(P＜0.001).The mean recovery rate of neurological func-tion was 85.9％.By comparing the imaging examinations postoperatively and six months after the opera-tion,we found that the average subsidence length was(1.2±1.1)mm,and that there was only one ca-ses(9.1％)of the severe subsidence(＞3 mm).We observed significant improvement of cervical lor-dosis after the operation(P=0.013).All the cases obtained solid fusion.Conclusion:3D-printing stand-alone AVB presented favorable short-term outcome in one-level ACCF in this study.The fusion rate of this zero-profile prosthesis was satisfactory and the complication rate was relatively low.

Objectives:To investigate the incidence and risk factors of perioperative complications after en bloc resection for thoracic and lumbar spinal tumors.Methods:The data of patients with thoracic and lumbar spinal tumors treated in our department with en bloc resection and anterior column reconstruction were retro-spectively analyzed.Between May 2016 and October 2022,90 consecutive patients underwent en bloc resec-tion on the basis of Weinstein-Boriani-Biagini surgical staging system,and anterior reconstruction was per-formed using 3D-printed artificial vertebral bodies.The demographic,oncological,and operative data of the patients were collected prospectively,and the intraoperative and postoperative complications occurring within three months were categorized into major and minor complications according to their impacts on the recovery process(Major complications were considered as any complication that appeared to substantially alter an other-wise full and expected course of recovery,and other complications were regarded as minor).All the patients were divided into the primary group(n=67)and revision group(n=23)based on their previous surgical history.Differences between the two groups in terms of age,gender,pathological type,tumor-involved segments,oper-ative time,intraoperative blood loss,and perioperative complications were compared.The predictive factors for major and minor complications were explored.Results:En bloc resection was achieved in all the patients,in-cluding total en bloc spondylectomy in 77 cases,sagittal resection in 12 cases,and vertebrectomy in one case.The mean operative time was 553.4min(210-1208min),and the mean intraoperative blood loss was 1534.1mL(260-5500mL).A total of 129 complications were observed in 65(72.2%)patients,including 29 ma-jor complications in 21(23.3%)patients.Two patients(2.2%)died as a result of complications.The revision group was more than primary group in tumor-involved segments(P=0.000)and incidence rate of major compli-cations(P=0.038).In univariate regression analysis,the combined approach[odds ratio(OR)=14.778,P=0.001],total blood loss(OR=1.004,P=0.004),staged surgery(OR=5.250,P=0.008),previous surgical history(OR=2.946,P=0.043),number of tumor-involved vertebrae(OR=1.607,P=0.023)and lumbar tumor(OR=3.509,P=0.015)were statistically significant risk factors for major complication occurrence,while the combined approach(OR= 6.375,P=0.036)was the independent risk factor.Conclusions:En bloc resection and anterior column recon-struction is associated with high risks of complications,especially when a combined approach is needed.

Objective:To investigate the predictive value of Doppler ultrasonography combined with cytokeratin fragment 19 (Cyfra21-1) and soluble interleukin-2 receptor (sIL-2R) in cervical lymph node metastasis of thyroid micropapillary carcinoma.Methods:102 patients with minimal papillary carcinoma of thyroid confirmed by surgery and pathology admitted to Ultrasound Department, Shanxi Cancer Hospital from Aug. 2020 to Aug. 2023 were selected and treated with thyroidectomy plus central region and at least one cervical lymph node dissection. Among them, There were 24 cases in the LLNM group and 78 cases in the non-LLNM group.Results:There were significant differences in age, shape, nodular and capsule contact area, tumor shape aspect ratio > 1, blood flow, microcalcification, serum Cyfra21-1 and serum sIL-2R levels between the two groups (Cyfra21-1: P<0.001, sIL-2R: P=0.001). Logistic regression analysis showed that age ≥50 years old ( OR=0.443, 95% CI: 0.217-0.904), microcalcification ( OR=2.787, 95% CI: 1.491-5.208), Cyfra21-1>3.3ng/ml ( OR=3.117, 95% CI: 1.404-6.922) and sIL-2R > 110.45pmol/L ( OR=3.408, 95% CI: 1.473-7.884) were independent risk factors for cervical lymph node metastasis in PTMC patients ( P < 0.05). The ROC curve results showed that the area under the curve of cervical lymph node metastasis predicted by Doppler ultrasound combined with Cyfra21-1 and sIL-2R was 0.82, and the sensitivity and specificity were 83.67% and 70.56%, respectively. Conclusions:The calcification features of Doppler ultrasound and the elevation of serum Cyfra21-1 and sIL-2R are closely related to cervical lymph node metastasis of thyroid micropapillary carcinoma. The combination of Doppler ultrasound with serum Cyfra21-1 and sIL-2R has important reference value in predicting cervical lymph node metastasis.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
