Background: A simple superoposterior approach to thoracic transforaminal epidural injections (TFEIs) under ultrasonographic guidance was proposed to reduce zoster-associated pain (ZAP) involving multiple thoracic nerves and the likelihood of transitioning to postherpetic neuralgia (PHN). Methods: Patients were prospectively enrolled. Primary endpoints were the burden of illness (BOI) scores and epidural contrast spread. Secondary endpoints included number of needle insertion attempts, sensory blockade, hemodynamic changes, procedure time, radiation dose, adverse events, rescue analgesics, PHN incidence and EuroQoL 5-Dimension scores. Results: Thirty-five injections were performed in 27 patients. Median levels of cephalad-caudad epidural contrast spread were 3, 4, and 5 ml following injections of 2, 3, and 4 ml. Dorsal epidural spread was observed at levels 3, 4, and 5, whereas concurrent ventral spread was observed at levels 2, 3, and 4. BOI scores at 30–180 days significantly decreased (mean difference: −25.3, 95% CI [−57.4 to 6.6], P = 0.005), accounting for reduced rescue analgesic requirements and PHN occurrence and improved EuroQoL 5-Dimension scores. Median sensory blockade at 5 min post-procedure was at level 2, 3, and 4 after 2, 3, and 4 ml of therapeutic injectate. No significant hemodynamic changes were noted at 15 min post-injection. No serious adverse events were observed. Conclusions Spread of thoracic epidural contrast to all involved nerves was confirmed using this novel technique. Simplified needle placement reduced the technical difficulty and risk of complications. It might be a promising alternative approach for ZAP.

Objective To investigate the independent risk factors affecting the prognosis of chronic active antibody-mediated rejection (caAMR) after kidney transplantation. Methods A retrospective analysis was conducted on 61 patients who underwent renal biopsy and were diagnosed with caAMR. The patients were divided into caAMR group (n=41) and caAMR+TCMR group (n=20) based on the presence or absence of concurrent acute T cell-mediated rejection (TCMR). The patients were followed up for 3 years. The value of 24-hour urinary protein and estimated glomerular filtration rate (eGFR) at the time of biopsy in predicting graft loss was assessed using receiver operating characteristic (ROC) curves. The independent risk factors affecting caAMR prognosis were analyzed using the LASSO-Cox regression model. The correlation between grouping, outcomes, and Banff scores was compared using Spearman rank correlation matrix analysis. Kaplan-Meier analysis was used to evaluate the renal allograft survival rates of each subgroup. Results The 3-year renal allograft survival rates for the caAMR group and the caAMR+TCMR group were 83% and 79%, respectively. The area under the ROC curve (AUC) for predicting 3-year renal allograft loss was 0.83 ［95% confidence interval (CI) 0.70-0.97］ for eGFR and 0.78 (95% CI 0.61-0.96) for 24-hour urinary protein at the time of biopsy. LASSO-Cox regression analysis and Kaplan-Meier analysis showed that eGFR≤25.23 mL/(min·1.73 m²) and the presence of donor-specific antibody (DSA) against human leukocyte antigen (HLA) class I might be independent risk factors affecting renal allograft prognosis, with hazard ratios of 7.67 (95% CI 2.18-27.02) and 5.13 (95% CI 1.33-19.80), respectively. A strong correlation was found between the Banff chronic lesion indicators of renal interstitial fibrosis and tubular atrophy (P<0.05). Conclusions The presence of HLA class I DSA and eGFR≤25.23 mL/(min·1.73 m²) at the time of biopsy may be independent risk factors affecting the prognosis of caAMR.

Objective:To summarize the clinical and genetic characteristics of late-onset facioscapulohumeral muscular dystrophy type 1 (FSHD1) patients, and to compare the differences between late-onset and classic-onset FSHD1 patients.Methods:A retrospective analysis was conducted on the clinical and genetic data of genetically confirmed late-onset FSHD1 patients (age at onset30 years) between January 2007 and June 2024 from the Department of Neurology of Peking University First Hospital and the First Affiliated Hospital of Fujian Medical University. Classic-onset FSHD1 patients (10 yearsage at onset≤30 years) were matched 1∶1 according to sex and disease duration for comparison. The demographic information, the number of D4Z4 repeat units, the distal D4Z4 methylation levels, FSHD Clinical Score (CS), Clinical Severity Score (CSS), and Age-Corrected Clinical Severity Score (ACSS) of these patients were collected. Survival analysis was performed to compare the outcome of lower extremity involvement between late-onset and classic-onset FSHD1 patients. The correlation of the number of D4Z4 repeat units and D4Z4 methylation level with CS and ACSS was analyzed in late-onset FSHD1 patients.Results:A total of 61 patients with late-onset FSHD1 were enrolled, 33 (54.1%) of whom are female, with an age of 54.0 (46.0, 62.0) years and a disease duration of 14.0 (5.5, 22.5) years. Compared to classic-onset FSHD1 patients, late-onset patients exhibited significantly lower CS [7.0 (5.6, 8.4) vs 6.0 (4.4, 7.7), U=1 416.000, P=0.013], CSS [3.0 (2.8, 3.3) vs 3.0 (2.0, 4.0), U=2 352.000, P=0.010], and ACSS [189.2 (137.1, 241.3) vs 96.8 (61.3, 132.2), U=3 225.500, P0.001], and higher proportion of patients with limb girdle involvement but no facial muscle involvement [18.0% (11/61) vs 6.6% (4/61), χ2=3.725, P=0.054]. Kaplan-Meier survival analysis showed that the onset age of lower extremity involvement in late-onset patients (45 years, 95% CI 42-48 years) was significantly higher than that in classic-onset patients (24 years, 95% CI 21-27 years, χ2=61.012, P0.001). The duration from symptom onset to lower extremity involvement in late-onset patients (15 years, 95% CI 10-20 years) was significantly longer than that in classic-onset patients (8 years, 95% CI 3-13 years, χ2=9.105, P=0.003). Late-onset FSHD1 patients carried higher average distal D4Z4 methylation levels compared to those with classic-onset FSHD1 [46.68% (40.79%,52.57%) vs 41.02% (34.03%,48.00%), U=1 378.500, P=0.014]. Among late-onset FSHD1 patients, cytosine-phosphate-guanine 6 (CpG6) methylation levels were significantly negatively correlated with ACSS ( r=-0.278, P=0.025); the number of D4Z4 repeat units were significantly negatively correlated with ACSS ( r=-0.272, P=0.034);CpG6 methylation levels were significantly negatively correlated with CS ( r=-0.441, P=0.003), while no correlation was found between number of D4Z4 repeat units and CS ( r=-0.161, P=0.310). Conclusions:Compared with classic-onset FSHD1 patients, late-onset FSHD1 patients are associated with a higher degree of distal D4Z4 methylation, along with a milder muscle weakness phenotype, slower disease progression and a higher proportion of cases without facial muscle involvement. The age at onset can be used as a marker of the severity and prognosis in FSHD1.

Objective To determine the effect of limb dominance on landing biomechanics and lower limb functional outcomes in patients with anterior cruciate ligament reconstruction(ACLR).Methods Forty-nine participants were recruited and divided into the ACLR on dominant limb(ACLR-D)group,ACLR on nondominant limb(ACLR-ND)group and healthy control group.Single-leg jump landing,knee isokinetic muscle strength,Y balance,and single-leg hop distance were tested on both limbs of all participants.Kinematics and kinetics data during the single-leg jump landing were collected by an infrared motion capture system and a force platform,and knee joint muscle strength was collected using the isokinetic muscle strength testing system.Two-way mixed-design ANOVAs were used to observe the effects of limb and group on the outcomes of each test.Results The non-surgical limbs had greater knee valgus,knee external rotation angles and knee valgus moments during single-leg jump landing in the ACLR-D group compared with those in the ACLR-ND group,and the ACLR-D group had significantly smaller bilateral knee flexion angles than the control group.There were no differences in knee muscle strength,Y-balance composite scores and single-leg hop distance between ACLR-D and ACLR-ND groups,but the Y balance scores in the ACLR-ND group were smaller than those in the control group.Conclusions Limb dominance has no effects on knee muscle strength,dynamic postural control,and single-leg hop function in ACLR patients.The non-surgical limbs of ACLR-D patients are at a higher risk of ACL injury due to the presence of greater knee valgus and external rotation angles and knee valgus moments.

Objective:To investigate variation of peripheral blood monocyte subtypes in patients with rheumatoid arthritis(RA),to study variation of surface antigen expression intensity and plasma related cytokine content of monocytes of each subtype,and to discuss their clinical application value.Methods:Percentage of monocyte subtypes and mean fluorescence intensity(MFI)of monocyte surface markers(HLA-DR,CD64,CD11b)in peripheral blood of 38 patients with RA were detected by multi-parameter flow cytometry,and differences were statistically analyzed compared with 40 healthy controls(HV group).Plasma levels of five cyto-kines(IL-2,IL-6,IL-10,TNF-α and IFN-γ)were detected by flow fluorescence microsphere technology.Linear correlation analysis was performed to determine correlation between percentage of monocyte subtypes and MFI of their surface markers and expression of related cytokines in RA patients.Disease activity 28(DAS28)score was performed in RA patients to study its association with percent-age of monocyte subtypes and plasma cytokines.Results:Compared with control group,percentage of classical monocytes in RA pa-tients decreased significantly(P<0.05),while percentage of intermediate monocytes and non-classical monocytes increased signifi-cantly(P<0.01).HLA-DR expression(MFI)on monocyte subsets in RA group was significantly higher than HV group(P<0.05 or P<0.01).CD64 expression(MFI)on intermediate monocytes and non-classical monocytes in RA group was significantly higher than HV group(P<0.01 or P<0.001).CD11b expression(MFI)on intermediate monocytes in RA group was significantly higher than HV group(P<0.001).In RA group,percentage of intermediate monocytes was positively correlated with contents of IL-6,TNF-α and IFN-γ(P<0.01).HLA-DR expression(MFI)on intermediate monocytes was positively correlated with TNF-α content(P<0.05);CD64 expres-sion(MFI)on non-classical monocytes was positively correlated with contents of IL-2 and IL-10(P<0.05).In RA group,percentage of intermediate monocytes was positively correlated with DAS28(P<0.001);plasma IL-6 and TNF-α levels were positively correlated with DAS28(P<0.01).Conclusion:Characteristic expression of intermediate monocytes and their surface antigens are closely related to occurrence of RA,and related inflammation is triggered by secretion of related cytokines.Monocyte subtype detection can be a new experimental diagnostic index for RA.Dynamic monitoring of peripheral blood monocyte subtypes and plasma IL-6 and TNF-α in RA patients during treatment is helpful to guide clinical treatment of RA.

Metagenomic next-generation sequencing (mNGS) has emerged as a pivotal tool in the detection and characterization of infectious pathogens in clinical settings, and it has been applied to donor assessment. This case report describes the effective application of mNGS in preventing the transplantation of organs from a donor infected with the rabies virus, who presented with myocarditis. The rapid and accurate identification of the rabies virus through mNGS potentially averted the risk of transmission to organ recipients.
