Objective: To evaluate the effectiveness and safety of the tonifying spleen and reinforcing Qi (TSRQ) therapy combined with thyroid hormone replacement therapy (THRT) for treating Hashimoto’s hypothyroidism. Methods: From database foundation to January 14, 2025, PubMed, Web of Science, Cochrane, Embase, China National Knowledge Infrastructure (CNKI), Wanfang Data, China Science and Technology Journal Database (VIP), and China Biomedical Literature Database (CBM) were searched for relevant information. Randomized clinical trials (RCTs) evaluating the efficacy and safety of TSRQ therapy combined with THRT for Hashimoto’s hypothyroidism were eligible for inclusion. Following quality assessment, data were analyzed using Stata 15.1 to conduct a meta-analysis and systematic review. Subgroup analysis was used to identify the sources of heterogeneity. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was adopted to evaluate the certainty of the evidence. Results: This study included 30 RCTs, comprising 2 687 patients with Hashimoto’s hypothyroidism. Overall methodological quality was acceptable, with no studies exhibiting a high risk of bias. Meta-analysis demonstrated that TSRQ therapy combined with THRT significantly enhanced serum free triiodothyronine (fT3) levels [standardized mean difference (SMD) = 0.76, 95% confidence interval (CI): 0.57 to 0.94, P < 0.001] and free thyroxine (fT4) levels (SMD = 0.86, 95% CI: 0.61 to 1.11, P < 0.001), while reducing thyroid-stimulating hormone (TSH) levels (SMD = – 0.99, 95% CI: – 1.20 to – 0.78, P < 0.001) compared with THRT alone. Furthermore, the combination therapy significantly decreased anti-thyroid peroxidase antibody (TPOAb) levels (SMD = – 1.46, 95% CI: – 1.79 to – 1.13, P < 0.001) and anti-thyroglobulin antibody (TgAb) levels (SMD = – 1.46, 95% CI: – 1.80 to – 1.11, P < 0.001). TSRQ therapy did not adversely impact the safety profile of THRT. However, while some sources of heterogeneity have been identified (e.g., specific detection methodologies, I² = 0.0%, P = 0.938), there remains a portion of unexplained heterogeneity (e.g., publication year, I² = 93.4%, P < 0.001), which has undermined confidence in these pooled estimates. The evidence ratings for fT3, fT4, and TSH were limited, and those for TPOAb and TgAb were even more limited. Conclusion TSRQ therapy combined with THRT may strengthen thyroid function and modulate immune dysregulation in patients with Hashimoto’s hypothyroidism without increasing adverse event incidence.

Objective:Comprehensive characterization of B-cell phenotypes and spatial distribution in oral lichen planus (OLP) and related oral lichenoid lesions (OLL)(OLP/OLL), with an emphasis on transcriptomic profiling and functional analysis, to uncover the epigenetic mechanisms underlying B cell-mediated immune regulation within the oral mucosal microenvironment.Methods:Single-cell RNA sequencing raw data were sourced from the GSE211630 database, encompassing samples from 2 cases of erosive OLP (EOLP), 3 cases of non-erosive OLP (NEOLP) and 1 healthy control (NORMAL). Following stringent quality control, the data underwent normalization, selection of highly variable genes and batch effect correction. Subsequent analyses included dimensionality reduction and unsupervised clustering to identify distinct cell populations. This study collected pathological specimens from 3 OLP/OLL patients and 3 healthy controls who were treated at the Department of Oral Medicine, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January 2021 to December 2023. Using 10X Genomics Visium HD spatial transcriptomics technology, tissue sections were processed through dewaxing, staining and histological imaging, enabling the reconstruction of nucleic acid structures and the capture of gene expression profiles. Data analysis included quality assessment, gene quantification, normalization, dimensionality reduction and clustering. Furthermore, cell type deconvolution was performed using the robust cell type decomposition algorithm, integrating single-cell transcriptomic data to accurately predict and spatially resolve cell type distributions within the tissue microenvironment.Results:After integrating single-cell data from EOLP, NEOLP and NORMAL, cells were classified into seven major categories: B/plasma cells, endothelial cells, epithelial cells, fibroblasts, myeloid cells, smooth muscle cells and T/natural killer cells. The proportion of B/plasma cells varied significantly among the three groups, accounting for 10.7% (1 693/15 815), 3.8% (833/21 653) and 0.4% (47/11 556) of the total cells respectively. Further clustering analysis of B/plasma cells identified four distinct subpopulations: naive B cells, activated B cells, memory B cells and plasma cells. In the EOLP group, these subpopulations constituted 25.9% (348/1 344), 45.9% (617/1 344), 3.3% (45/1 344) and 24.9% (334/1 344) of the B/plasma cells respectively. In the NEOLP group, they represented 31.6% (195/617), 59.6% (368/617), 0.2% (1/617) and 8.6% (53/617). Howerer, only plasma cells were detected in the NORMAL group. Spatial analysis revealed that B cells were actively involved in the formation of tertiary lymphoid structures (TLS) at various stages in OLP/OLL samples, with a prominent structural organization observed in secondary follicle-like TLS. Within these structures, the expressions of T cells marker gene CD3E and B cells marker gene MS4A1 were significantly elevated. Additionally, in secondary follicle-like TLS, the gene encoding follicular dendritic cell secreted protein, germinal center marker gene B cell lymphoma 6 and the gene for activation induced cytidine deaminase also showed strong expression. In OLP/OLL samples, plasma cell marker gene CD38, immunoglobulin (IGH) G3, IGHG1, IGHM, IGHD, IGHE, imunoglobulin Kappa constant, immunoglobulin alpha 1, immunoglobulin Lambda constant 1 and complement gene C3 all exhibited high levels of expression.Conclusions:Compared to normal mucosa, extensive B-cell infiltration is observed in both OLP and OLL, accompanied by significant differences in B-cell phenotypes and proportions. B cells appear to play a central role in local immune responses, primarily through the formation of TLS. However, the precise functional mechanisms underlying their involvement require further investigation.

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.

Objective:To compare the efficacy between Kirschner wire and clavicular hook plate in the fixation of distal clavicle fractures in older children.Methods:A retrospective analysis was conducted of the 28 pediatric patients with distal clavicle fracture who had undergone surgical treatment at Department of Pediatric Orthopedics, The Second General Hospital of Fuzhou from December 2014 to December 2023. There were 20 boys and 8 girls. Age: 10.0 (9.0, 12.8) years old; 22 left sides and 6 right sides; by the Craig modified Neer classification: 22 cases of type Ⅱ, 5 cases of type Ⅳ, and 1 case of type Ⅴ. The patients were divided into 2 groups based on their internal fixation methods. The Kirschner wire group of 12 cases were treated with open reduction and Kirschner wire fixation; the hook plate group of 16 cases were treated with open reduction and clavicular hook plate fixation. Operation time, hospital stay, fracture healing time, incidence of complications, and scores at the final follow-up (the Constant-Murley shoulder function score, quick disabilities of the arm, shoulder, and hand (quickDASH) score, and visual analog scale (VAS) for aesthetic satisfaction) were recorded and compared between the 2 groups.Results:There were no statistically significant differences in the baseline data between the 2 groups, indicating comparability ( P>0.05). The postoperative follow-up period for the 28 patients was (14.8±6.5) months. The operation time in the Kirschner wire group [(34.3±12.1) min] was significantly shorter than that in the hook plate group [(49.4±16.8) min] ( P<0.05), and the VAS score for aesthetic satisfaction at the final follow-up in the Kirschner wire group [(8.2±1.1) points] was significantly higher than that in the hook plate group [(6.2±2.6) points] ( P<0.05). There were no statistically significant differences between the 2 groups in terms of fracture healing time, hospital stay, incidence of complications, or Constant-Murley score and quickDASH score at the final follow-up ( P>0.05). Conclusions:For pediatric patients with distal clavicle fracture, both Kirschner wire fixation and clavicular hook plate fixation can achieve good functional outcomes. However, Kirschner wire fixation has advantages of shorter operation time, higher postoperative aesthetic satisfaction, and no need of a secondary surgery for implant removal.

Objective:To assess the prognostic value of pretreatment 18F-FDG PET/CT metabolic parameters in patients with metastatic malignant melanoma treated with anti-programmed cell death-1 (PD1) immunotherapy. Methods:A retrospective analysis of 29 patients (15 males, 14 females, age (59.1±13.0) years) with pathologically diagnosed metastatic malignant melanoma in Nanjing Drum Tower Hospital between June 2017 and October 2020 was conducted. Anti-PD1 immunotherapy were performed in all patients after 18F-FDG PET/CT imaging. 18F-FDG PET/CT parameters including SUV max, bone marrow-to-liver SUV max ratio (BLR), spleen-to-liver SUV max ratio (SLR) were obtained. Total metabolic tumor volume (TMTV) and total lesion glycolysis (TLG) of primary lesions were measured automatically using the thresholds of 40%SUV max. The median value of each PET parameter was regarded as the threshold value and was used to divide patients into 2 groups (≥ and < the median value, respectively). Kaplan-Meier survival curve and Cox proportional risk model were used to analyze the overall survival (OS) differences between groups. Results:The median follow-up time was 15.0 months and 13 patients died. The median OS was 26.0(95% CI: 20.4-31.6) months. The median SUV max, TMTV, TLG, BLR and SLR were 6.2, 8.2 cm 3, 38.6 g, 0.82 and 0.84 respectively. Kaplan-Meier method and log-rank test showed that differences of OS between SUV max≥6.2 and <6.2 groups, TLG≥38.6 g and <38.6 g groups, BLR≥0.82 and <0.82 groups, SLR≥0.84 and <0.84 groups were not significant ( χ2 values: 0.01-0.35, P values: 0.061-0.929), while patients with TMTV≥8.2 cm 3 suffered from poorer OS compared with those with TMTV<8.2 cm 3 ( χ2=5.90, P=0.015). Cox multivariate analysis showed that TMTV (hazard risk ( HR)=6.347, 95% CI: 1.039-38.789) was a significant predictor of OS ( P=0.045). Conclusion:18F-FDG PET/CT parameter TMTV is the independent predictive factor of OS in metastatic melanoma treated with anti-PD1 immunotherapy.

Objective:To investigate the prognostic value of metabolic parameters measured by 18F-FDG PET/CT in patients with primary advanced cutaneous malignant melanoma (CMM). Methods:A retrospective analysis was comprised of 42 patients with advanced CMM (15 males and 27 females; median age: 60.0 years) from Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School between June 2014 and December 2019. All patients were initially diagnosed by pathology, and underwent 18F-FDG PET/CT imaging. 18F-FDG PET/CT parameters including SUV max, SUV mean, total metabolic tumor volume (TMTV) and total lesion glycolysis (TLG) of metastatic lesions were measured. ROC curve analysis was performed to obtain the optimal cut-off values of those metabolic parameters for predicting progression-free survival (PFS) and over-all survival (OS). Patients were divided into different groups based on their metabolic parameters (≥cut-off values or
