Purpose:
We used bioinformatics methods and Mendelian randomization (MR) analysis to investigate the hub genes involved in acute myeloid leukemia (AML) and their causal relationship with hemolysis, to explore a new direction for molecular biology research of AML.
Methods:
We first differentially analyzed peripheral blood samples from 62 healthy volunteers and 65 patients with AML from the Gene Expression Omnibus database to obtain differentially expressed genes (DEGs), and intersected them with genes sourced from weighted gene co-expression network analysis (WGCNA) and the GeneCards database to obtain target genes. Target genes were screened using protein–protein interaction (PPI) network analysis and ROC curves to identify genes associated with AML. Finally, we analyzed the correlation between genes and immune cells and the relationship between toll-like receptor 4 (TLR4) and AML using MR.
Results:
We compared peripheral blood expression profiles using an array of 62 healthy volunteers (GSE164191) and 65 patients with AML (GSE89565) (M0:25; M1:11; M2:10; M3:1; M4:7; M4 eo t [16;16] ou inv [16]:4; M5:6; M6:1) and obtained 7,339 DEGs (3,733 upregulated and 3,606 downregulated). We intersected these DEGs with 4,724 genes from WGCNA and 1,330 genes related to hemolysis that were identified in the GeneCards database to obtain 190 target genes. After further screening these genes using the PPI network, we identified TLR4, PTPRC, FCGR3B, STAT1, and APOE, which are closely associated with hemolysis in patients with AML. Finally, we found a causal relationship between TLR4 and AML occurrence using MR analysis (p < 0.05).
Conclusion
We constructed a WGCNA-based co-expression network and identified hemolysis-associated AML genes.

Purpose:
To investigate the short-term outcomes of intravitreal injections of the ranibizumab biosimilar SB11 in patients with neovascular age-related macular degeneration (AMD).
Methods:
This retrospective comparative study assessed changes in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) in patients diagnosed with neovascular AMD who received three monthly injections of SB11. The outcomes were compared to those of patients who received the same treatment using the ranibizumab originator. Within the SB11 group, comparisons were made between BCVA and CRT at diagnosis and after three injections. The proportion of patients with resolved subretinal fluid/intraretinal fluid was also evaluated.
Results:
The study included 46 eyes. In the SB11 group (n = 23), the average BCVA improved significantly from a baseline of logarithm of minimal angle of resolution 0.54 ± 0.42 to 0.40 ± 0.32 after three injections (p = 0.008). The average CRT decreased significantly from 447.4 ± 167.7 µm at baseline to 267.9 ± 66.9 µm after treatment (p < 0.001). Complete resolution of macular edema was observed in 19 eyes (82.7%). No significant differences were found in the degree of change in BCVA (p = 0.883) and CRT (p = 0.629) when compared to the ranibizumab originator group (n = 23). No complications such as intraocular inflammation or retinal detachment were noted.
Conclusions
Treatment with SB11 loading injections in neovascular AMD led to significant improvements in vision and reductions in macular thickness. The extent of improvement was comparable to that achieved with the ranibizumab originator and no severe complications were observed.

Purpose:
Adjuvant chemotherapy (AC) is recommended for muscle-invasive or lymph node-positive upper urinary tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). However, disease recurrences are frequently observed in pT1 disease, and AC may increase the risk of overtreatment in pT2 UTUC patients. This study aimed to validate a risk-adapted scoring model for selecting UTUC patients with ≤pT2 disease who would benefit from AC.
Materials and Methods:
We retrospectively analyzed 443 ≤pT2 UTUC patients who underwent RNU. A risk-adapted scoring model was applied, categorizing patients into low- or high-risk groups. Recurrence-free survival (RFS) and cancer-specific survival (CSS) were analyzed according to risk group.
Results:
Overall, 355 patients (80.1%) and 88 patients (19.9%) were categorized into the low- and high-risk groups, respectively, with the latter having higher pathological stages, concurrent carcinoma in situ, and synchronous bladder tumors. Disease recurrence occurred in 45 patients (10.2%), among whom 19 (5.4%) and 26 (29.5%) belonged to the low- and high-risk groups, respectively (p<0.001). High-risk patients had significantly shorter RFS (64.3% vs. 93.6% at 60 months; hazard ratio [HR] 13.66; p<0.001) and worse CSS (80.7% vs. 91.5% at 60 months; HR 4.25; p=0.002). Multivariate analysis confirmed that pT2 stage and the high-risk group were independent predictors of recurrence and cancer-specific death (p<0.001). Decision curve analysis for RFS showed larger net benefits with our model than with the T stage model.
Conclusions
The risk-adapted scoring model effectively predicts recurrence and identifies optimal candidates for AC post RNU in non-metastatic UTUC.

We constructed a WGCNA-based co-expression network and identified hemolysis-associated AML genes.

ObjectiveThis study explored the application of Yiqi Zengmian prescription as a vaccine adjuvant, aiming to provide a new scheme for the prevention and control of corona virus disease 2019(COVID-19) with traditional Chinese medicine (TCM). By analyzing the compatibility and efficacy, this paper examines the compatibility effect of Yiqi Zengmian prescription, which is modified from the classic tonifying agent Si Junzitang, as a vaccine adjuvant. MethodUsing the Database of Ancient Classical Prescriptions, this paper analyzed the composition of Yiqi Zengmian prescription and probed into the theoretical basis for the compatibility of this prescription from the properties, medicine combination, and efficacy. Furthermore, the compatibility effect of this prescription with vaccines was analyzed. ResultAs a TCM prescription, Yiqi Zengmian prescription focuses on the lung and spleen and enhances the Qi in the two organs. The lung governs Qi movement. The body breathes fresh air through the lungs and exchanges the turbid gas in the lungs, and the gas circulates alternately in the lungs to ensure the normal breathing of the human body. The spleen governing transportation and transformation is the hub for Qi movement, and Qi is the embodiment of metabolic function. By regulating qi movement and enhancing the functions of Qi and blood, Yiqi Zengmian prescription can enhance the immunogenicity of the vaccine, which provides a theoretical basis for enhancing the immune effects of vaccines. ConclusionYiqi Zengmian prescription has the effects of replenishing Qi and invigorating spleen, regulating Qi and drying dampness, and enhancing immunity. The in-depth analysis of the TCM theory of Yiqi Zengmian prescription as a vaccine adjuvant and the results of clinical and laboratory studies suggest that Yiqi Zengmian prescription may enhance the induction of immune response after vaccination and maintain the immune memory. However, the mechanism of Yiqi Zengmian prescription in regulating the complex immune network remains to be elucidated.

Purpose To explore the molecular features of diffuse large B-cell lymphoma(DLBCL)with high expression of MYC.Methods The clinical data of 45 cases of DLBCL were collected.Immunohistochemical EnVision method was used to classify the patients into the group with high expression of MYC and the group with low expression of MYC.All samples were subjected to DNA targeted sequencing and molecular typing was performed using the LymphGen online tool.Cellular origin was determined by using the Lymph2Cx method.The correlation be-tween MYC overexpression and clinicopathological parameters was analyzed by the x2 test and Fisher precise test.Survival curves were drawn and survival-related factors were analyzed u-sing Cox univariate and multivariate regression.ResultsCases were classified into DLBCL with high expression of MYC(n=17)and DLBCL with low expression of MYC(n=28).Com-pared to the group with low expression of MYC,the group with high expression of MYC had more PIM1,MYD88,CD79B,CD58 and PRDM1 mutations(76.5%vs 28.6%,70.6%vs 32.1%,58.8%vs28.6%,29.4%vs3.6%,29.4%vs 3.6%,P<0.05),MCD were more frequently found(58.8%vs 10.7%,P=0.001),GCB were rarely found(17.6%vs 50.0%,P=0.030).Overall survival was significantly shorter in DLBCL with high expression of MYC(P<0.05).Cox multi-factorial analysis showed that age was an independent prognostic factor for DLBCL(P<0.05).Conclusion Patients with high expression of MYC were frequently characterized as MCD and ABC,and PIM1,MYD88,CD79B,CD58 and PRDM1 muta-tions were common.Patients with high expression of MYC had a poorer prognosis.
