The transcription factor HOXB13 plays crucial roles in cancer development. HOXB13 is abnormally expressed in most cancers, which makes it a valuable therapeutic target for cancer therapy. The level of HOXB13 differs significantly between healthy and cancer tissues, which indicates that the level of HOXB13 is closely related to carcinogenesis. The regulatory network mediated by HOXB13 in cancer proliferation, metastasis, and invasion has been systematically investigated. Moreover, HOXB13 variants play distinct roles in different cancers and populations. By understanding the molecular mechanisms and mutation features of HOXB13, we provide a comprehensive overview of carcinogenesis networks dependent on HOXB13. Finally, we discuss advancements in anticancer therapy targeting HOXB13 and the roles of HOXB13 in drug resistance to molecular-targeted therapies, which serves as a foundation for developing HOXB13-targeted drugs for clinical diagnosis and cancer therapies.

Objective To quantify the association between obesity and erectile dysfunction (ED) risk through a meta-analysis. Methods Following PRISMA guidelines, systematic searches of Chinese and English databases (up to March 2025) were conducted to include observational studies (cohort, cross-sectional, case-control). Adjusted effect sizes (OR and 95% CI) were extracted. Study quality was assessed using the Agency for Healthcare Research and Quality(AHRQ) scale, and a random-effects model was applied to pool effect sizes. Subgroup analyses (geographic region, obesity definitions) and sensitivity analyses were performed to validate robustness. Results Ten studies (n=230 744), including nine cross-sectional studies, were included. The meta-analysis revealed that obesity significantly increased ED risk (random-effects OR=1.80, 95% CI: 1.29-2.51), with high heterogeneity (I2=99.9%). Subgroup analyses indicated stronger associations in USA populations (OR=2.10, 95% CI: 1.23-3.60) than in Chinese populations (OR=1.16, 95% CI: 1.05-1.28). The highest effect size was observed when using BMI≥25 kg/m3 as the obesity threshold (OR=3.05, 95% CI: 2.06-4.51). Sensitivity analyses confirmed robust results (OR: 1.60-1.94 after excluding any single study). Conclusions Obesity is a critical risk factor for ED, with effect strength influenced by geographic region and obesity definitions. Interventions targeting BMI≥30 kg/m2 in Western populations and metabolic risks at BMI≥25 kg/m3 in Asian populations are recommended.

Objective:To explore the expression of 7-dehydrocholesterol reductase (DHCR7) in gastric cancer using bioinformatics methods and its relationship with clinical pathological characteristics and prognosis of gastric cancer patients.Methods:DHCR7 expression in gastric cancer was analyzed using the UALCAN database; DHCR7 mRNA expression and its relationship with the prognosis of gastric cancer patients were analyzed using the Kaplan-Meier plotter database; The expression of DHCR7 and its correlation with tumor immune infiltration level were analyzed using Sangerbox 3.0 and TIMER database; Real-time fluorescence quantitative PCR was used to detect the expression of DHCR7 mRNA in gastric cancer tissues and adjacent tissues; immunohistochemical staining was conducted to detect the DHCR7 expression in gastric cancer tissues and adjacent tissues and its correlation with clinical pathological parameters; Receiver operator characteristic (ROC) curve was used to evaluate the efficacy of DHCR7 expression in the diagnosis of gastric cancer.Results:The analysis results of the UALCAN database showed that there were statistically significant differences in DHCR7 mRNA expression among gastric cancer patients of different genders ( χ2=18.15, P<0.001), grades ( χ2=16.32, P<0.001), and TP53 mutation status ( χ2=20.12, P<0.001). Survival analysis showed that the 10-year overall survival (OS) rate ( HR=1.55, 95% CI: 1.31-1.84, P<0.001), 10-year progression free survival (PFS) rate ( HR=1.67, 95% CI: 1.36-2.05, P<0.001), and 10-year post progression survival (PPS) rate ( HR=1.81, 95% CI: 1.43-2.28, P<0.001) of gastric cancer patients with high DHCR7 expression were significantly lower than those with low DHCR7 expression. Immune infiltration analysis showed the expression of DHCR7 was negatively correlated with the comprehensive score ( r=-0.51, P<0.001), stromal cell score ( r=-0.48, P<0.001), immune cell score ( r=-0.45, P<0.001), CD4 + T cells ( r=-3.01, P<0.001), macrophages ( r=-0.40, P<0.001), neutrophils ( r=-0.32, P<0.001), and dendritic cells ( r=-0.37, P<0.001) infiltration levels in gastric cancer, and positively correlated with the purity of gastric cancer cells ( r=0.15, P<0.001). The qRT-PCR results showed that compared with adjacent tissues (1.86±0.51), the expression of DHCR7 in gastric cancer tissues (3.43±0.13) was significantly upregulated, with a statistically significant difference ( t=42.89, P<0.001). The relative expression level of DHCR7 in normal gastric mucosal cells GES-1 was 1.06±0.19, and the relative expression levels in four types of gastric cancer cells (HGC-27, AGS, SNU-1, and SGC-7901) were 2.40±0.26, 1.88±0.11, 1.51±0.04, and 2.63±0.20, respectively, there were statistically significant differences in the expression of DHCR7 among the five types of cells ( F=38.34, P<0.001), and the relative expression level of DHCR7 in normal gastric mucosal cells was statistically significant different compared to the four types of gastric cancer cells mentioned above ( P=0.002; P=0.003; P=0.017; P<0.001) ; The immunohistochemical results showed that the high expression rate of DHCR7 in gastric cancer tissues was 80.0% (96/120), which was significantly higher than that in adjacent tissues (68.3%) (82/120) ( χ2=56.84, P<0.001). There were statistically significant differences in tumor maximum diameter ( χ2=40.17, P<0.001), histological grade ( χ2=16.20, P<0.001) and pTNM stage ( χ2=16.99, P<0.001) between patients with high and low DHCR7 expression. The ROC curve results showed that the area under the curve (AUC) of DHCR7 expression level for diagnosing gastric cancer were 0.76 (based on TCGA database, 95% CI: 0.68-0.83, P<0.001) and 0.97 (120 clinical samples of gastric cancer, 95% CI: 0.95-0.99, P<0.001), respectively. Conclusions:DHCR7 is highly expressed in gastric cancer and closely associated with poor prognosis in patients, which may be a novel biomarker for the diagnosis and prognosis of gastric cancer.

ObjectiveTo comprehensively elucidate the potential mechanisms of Xiao Xumingtang （XXMT） combined with electroacupuncture （EA） collaboratively in alleviating cerebral ischemia/reperfusion （I/R） injury. MethodThe rat model of cerebral I/R injury was established using the modified suture-occluded method. Seven days after modeling， rats in the XXMT+EA groups were administered XXMT at low （15 g·kg^-1）， medium （30 g·kg^-1）， and high （60 g·kg^-1） doses， alongside daily 20-min EA treatment （stimulating acupoints GV14 and GV20）. Cerebral infarction and neuronal damage were evaluated using the Zea Longa test score， TTC staining， and TUNEL staining. Real-time fluorescence quantitative PCR and Western blot were used to detect the expression of NOD-like receptor hot protein domain related protein 3 （NLRP3）， Gasdermin D （GSDMD）， cysteinyl aspartate specific proteinase-1 （Caspase-1）， interleukin-1β （IL-1β）， and interleukin-18 （IL-18） in the ischemic area of the cerebral cortex. ResultCompared with the sham group， the I/R group showed a significant increase in neurological deficit scores and infarct volume （P<0.01）， along with a higher apoptosis rate of cortical neurons and elevated mRNA and protein expression levels of NLRP3， GSDMD， Caspase-1， IL-1β， and IL-18 （P<0.05）. In contrast， the medium- and high-dose XXMT combined with EA treatment significantly reduced neurological deficit scores and infarct volume （P<0.01）， and decreased the apoptosis rate of cortical neurons as well as the mRNA and protein expression levels of NLRP3， GSDMD， Caspase-1， IL-1β， and IL-18 （P<0.05）. The improvement showed a dose-dependent relationship with XXMT. ConclusionThe combined use of XXMT and EA can exert neuroprotective effects by modulating the NLRP3/GSDMD/Caspase-1 signaling pathway， thereby reducing neurological deficits， minimizing brain infarct size， and improving cortical neuronal damage.

Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APC^min/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.

Objective To observe the role of dried tangerine peel in Yigong Powder improves iron metabolism and promotes red blood cell generation in anemia of chronic disease (ACD).Methods With a two-by-two factorial design,the Yigong Powder was divided into dried tangerine peel and Chenpi absent Decoction. According to the random number table method,32 zymosan-induced generalized inflammation (ZIGI) mice were randomly divided into the model group,the dried tangerine peel group,the Chenpi absent Decoction group,and the Yigong Powder group. The dried tangerine peel group,Chenpi absent Decoction group and the Yigong Powder group were given dried tangerine peel(3.083 g/kg),Chenpi absent Decoction(12.33g/kg),and Yigong Powder(15.413g/kg)by gavage to the corresponding group of mice. The model group was given an equal amount of physiological saline by gavage,and treated continuously for 7 days. After the completion of administration,the body weight of each group of mice was recorded. The hemoglobin content of each group of mice was detected using a fully automatic cell counter,the serum iron content was detected using colorimetry,the serum ferritin content was detected using enzyme-linked immunosorbent assay (ELISA),and the spleen index was calculated. The liver tissue inflammatory factors interleukin-1β (IL-1β),interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α),interferon-γ (IFN-γ),interleukin-4 (IL-4),and interleukin-10 (IL-10) levels were detected using Luminex method. The mRNA expressions of liver tissue hepcidin gene (HAMP) and membrane iron transporter ( Fpn) were detected using real-time fluorescence PCR method. Results Dried tangerine peel and Chenpi absent Decoction both showed interactive effects in regulating hemoglobin,serum iron,serum ferritin content,improving spleen index,and regulating the mRNA expressions of HAMP,Fpn,as well as IL-1β and IFN-γ (P<0.05). Compared with the model group,dried tangerine peel significantly increased hemoglobin,serum iron content,and Fpn mRNA expression in ZIGI model mice,while decreasing ferritin content,spleen index,HAMP mRNA expression,and the levels of IL-1β,IL-6,TNF-α,and IFN-γ (P<0.05). Chenpi absent Decoction significantly increased serum iron content and Fpn mRNA expression in ZIGI model mice,while reducing spleen index,ferritin content,HAMP mRNA expression,and the levels of IL-1β and IFN-γ、IL-4 (P<0.05). Conclusion The effects of dried tangerine peel on inflammatory factors (IL-6 and TNF-α) and Fpn may play a key role in the improvement effects of Yigong Powder on ACD and iron metabolism.

Objective The family reconstruction method was used to establish paternity index algorithm for uncle-nephew relationships between two full sibling uncles and one nephew.Methods According to Mendelian genetic law,the family of two known full-sib uncles and one nephew were reconstructed according to the relationship between uncle and nephew,and the test hypothesis was established between two full sibling uncles and one nephew as the uncle-nephew relationship and unrelated individuals,and the paternity index of the uncle-nephew relationship between two full sibling uncles and one nephew was calculated by using Excel.Results Among the 99 genotypic combinations between two full sibling uncles and one nephew,91 of which were consistent with the genetic rules of uncle-nephew relationships,while 8 of which were not.a stepwise mutation model was introduced in the situations that do not conform to the genetic laws of uncle-nephew relationships.The paternity index of uncle-nephew relationship between two full sibling uncles and one nephew can be calculated using Excel.Conclusion The uncle-nephew testing involved by two full sibling uncles makes use of the role of the assistant,and the paternity index of the obtained uncle-nephew relationship is higher than that between two known full-siblings alone and their nephew,which has a good practical value in helping the appraiser to draw a clear appraisal opinion.

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Objective:To study the precision of 3D printing coplanar template (3D-PCT) assisted CT-guided radioactive particle implantation using two types of phantoms, and compare the differences between the phantoms, in order to provide reference for radioactive particle implantation.Methods:The needle inserting path was designed in the brachytherapy treatment planning system (BTPS) and the needle tip coordinates were obtained. Following the needle inserting path, the implant needles were inserted into the custom and the liver phantoms, respectively. Then gold markers were implanted through the needles. Subsequently, the needles were withdrawn by 10 mm, and the cold sources were implanted. The coordinates of needle tips, gold markers, and cold sources were recorded. The precision of implanted needles, first particles, and particles after needle withdrawal were obtained by calculating the distance between two points in the space. Finally, the differences between the two phantoms were compared through independent samples t-test. Results:In the 3D-PCT-assisted CT-guided radioactive particle implantation, the precision of implanted needles, first particles, and particles after needle withdrawal in the custom and the liver phantoms was (1.89±0.72) and (2.14±0.88 ) mm ( P>0.05), (2.03±1.14) and (2.42±1.12) mm ( P>0.05), and (-1.96±1.29) and (-2.82±0.91) mm ( t=2.09, P=0.046), respectively. Conclusions:The 3D-PCT-assisted CT-guided radioactive particle implantation is efficient, stable, and precise, showing slight precision differences between the two phantoms.
