BACKGROUND:Black phosphorus has a high degree of homology with human bone,so it has been extensively studied in the field of bone tissue engineering in recent years.Since 2014,two-dimensional black phosphorus materials have garned significant attention in the field of biomedicine due to their excellent exceptional physical,chemical,and biological properties. OBJECTIVE:To summarize the advancements made in black phosphorus-based nanomaterials for bone tissue engineering,focus on the synthesis methods,osteogenic characteristics,and applications in biomaterials pertaining to two-dimensional black phosphorus nanomaterials. METHODS:Chinese and English key words were"black phosphorus,bone tissue engineering,bone defect,bone regeneration,osteogenesis."Relevant articles in PubMed and CNKI databases from January 2014 to December 2023 were searched.After exclusion and screening,96 articles were analyzed. RESULTS AND CONCLUSION:Black phosphorus nanomaterials play an important role in bone tissue engineering due to their good biocompatibility,biodegradability,photothermal action,antibacterial ability,drug loading performance,and special osteogenic effect,and are ideal candidate materials for promoting bone regeneration.The preparation of black phosphorus nanomaterials is mainly a top-down top-layer stripping method.The main principle is to weaken the van der Waals force between the black phosphorus layers by physical or chemical means to obtain a single or less layer of phosphanse,that is,black phosphorus nanosheets or quantum dots.Black phosphate-based nanocomposites are mainly divided into hydrogels,3D printing scaffolds,composite scaffolds,electrospinning,bionic periosteum,microspheres,and bionic coatings.The research of nano-black phosphorus in bone tissue engineering is in its infancy,and still faces many challenges:the behavior of black phosphorus in vivo and the interaction mechanism with various biomolecules need to be further studied.The long-term potential toxicity of black phosphorus is unknown.The manufacturing process for black phosphorus is difficult to control.Therefore,how to develop uniform size,safe,reliable,and efficient nano black phosphorus and transform it into clinical application requires interdisciplinary research on modern biomedical technology,physicochemical technology,and precision manufacturing technology.

The preferred treatment for adrenal functional tumors is laparoscopic surgical resection. However, in recent years, various ablation techniques have gradually been applied in the treatment of adrenal tumors. This report presents the successful diagnosis and treatment experience of 4 aldosterone-producing adenomas and 1 cortisol-secreting adenoma treated with a combined cold and hot ablation system at Xi’an Daxing Hospital from Dec. 2023 to Dec. 2024, providing a new treatment approach for clinical exploration.

Programmed cell death plays an important role in the growth and development of organ-ism and homeostasis of tissues and organs.Necroptosis,a new mode of programmed cell death,characterized by necrosis in morphology,can cause cell breakdown and release of a significant num-ber of damage-associated molecular patterns,which play an important role in the occurrence and development of diseases.Viral infection is a serious health risk to both humans and domestic ani-mals.Research has confirmed that necroptosis functions as a cell death pathway in viral infections.In this paper,we review the current research advances on necroptosis related to viral infections,e-lucidate the molecular mechanism of mutual regulation between viral infection and necroptosis,and discuss the progress in the application of necroptosis inhibitors,to provide new ideas for the pre-vention and treatment of viral infections.

We report a case of adult-onset Still's disease(AOSD)presenting with fever,myalgia,and pleural effusion.The patient exhibited significantly elevated inflammatory markers and exudative pleural effusion with markedly elevated leukocyte count showing neutrophilic predominance.After comprehensive exclusion of infectious etiologies,the diagnosis of AOSD was established.Clinical symptoms resolved following anti-inflam-matory therapy with glucocorticoids and tocilizumab.This case highlights a critical clinical insight:while infec-tion is a common cause of elevated inflammatory markers,it is not an invariable etiology.In such presentations,meticulous clinical observation,thorough diagnostic screening,and systematic inference are es-sential for accurate diagnosis.

This research aims to construct a stable epithelial cell senescence model for screening and e-valuation of senolytics.We explored the optimal conditions for doxorubicin-induced senescence of non-transformed epithelial cells MCF 10A,including the optimal induction concentration,the optimal inter-vention time,and the optimal senescence duration,and confirmed the feasibility of MCF 10A as an epi-thelial senescence model by multiple ways.The optimal condition for Doxorubicin-induced senescence of MCF 10A cells was treatment with 0.6 μmol/L Doxorubicin for 16 h to achieve the best senescence state on the 8th day.Under the optimal induction conditions,the positive rate of senescence-associated β-gal-actosidase(SA-β-gal)staining in the treated group reached 97％.At the same time,biochemical results of detecting the expression of mRNA,proteins,and immunofluorescence demonstrated that the expression levels of senescence-associated secretory phenotype(SASP),p16,p21 and p53 in the treated group were significantly higher than those in the control cells,and Lamin B1 was significantly decreased(P＜0.001),which were consistent with the specific characteristics of senescence.In summary,an epithelial senescence model was successfully induced in MCF 10A cells by Doxorubicin in this study,which will promote the screening of senolytics for senescent epithelial cells.

Pediatric T-cell acute lymphoblastic leukemia (T-ALL) has been attracted much attention due to its high aggressiveness and complexity of treatment. Recently, with the development of technology and clinical research, the curative effect of T-ALL in children has been significantly improved. However, the presence of minimal residual disease (MRD) is still a key factor affecting the outcomes of children with T-ALL. With the continuous development of detection methods, the clinical applications of real-time quantitative PCR, multi-parameter flow cytometry, and high-throughput sequencing technology, MRD can be detected accurately to achieve personalized and precise treatment for each patient. The purpose of this article is to review the current detection methods of MRD in T-ALL, the clinical significance of MRD monitoring and evaluation in multi-agent combined chemotherapy and hematopoietic stem cell transplantation, and applying MRD to measure the responsiveness and effectiveness of new therapies in recent T-ALLs. Research directions and potential treatment strategies in the near future were also proposed.

Objective:To compare the safety and efficacy of transarterial chemoembolization (TACE) combined with donafenib and programmed death protein 1 (PD-1) inhibitors and TACE combined with donafenib in the treatment of unresectable hepatocellular carcinoma (uHCC).Methods:Clinical data of 148 patients with uHCC treated at the First Affiliated Hospital of Zhengzhou University from December 2021 to December 2022 were retrospectively analyzed, including 127 males and 21 females, aged (56.6±9.9) years. Patients were divided into two groups: the TACE combined with donafenib and PD-1 inhibitors group (TACE+ DP, n=73) and TACE combined with single donafenib (TACE+ D, n=75). The overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and the occurrence of treatment-related adverse events (TRAEs) of the two groups of patients were observed. Kaplan-Meier analysis was used for survival assessment, and the log-rank test was used for comparison. The related factors affecting the prognosis of patients were indentified and analyzed. Results:The median PFS of patients in the TACE+ D group and the TACE+ DP group were 7.2 months (95% CI: 5.7-8.3 months) and 10.5months (95% CI: 8.9-11.3 months), respectively. The median OS was 13.2 months (95% CI: 12.3-13.7 months) and 16.9 months (95% CI: 15.1-19.8 months), respectively. All these differences were statistically significant ( χ2=17.81, 26.92, respectively, both P<0.001). The ORR and DCR of TACE+ DP group were both higher than those in TACE+ D group [53.4% (39/73) vs 36.0% (27/75), χ2=4.55, P=0.031; and 90.4% (66/73) vs 77.3% (58/75), χ2=4.66, P=0.044]. No grade 4 or above adverse events occurred in either the TACE+ DP or the TACE+ D group. The most common treatment-related adverse events in TACE+ D and TACE+ DP group were hand-foot syndrome [46.7% (35/75) vs 49.3% (36/73)], hypertension [26.7% (20/75) vs 30.1% (22/73)], fatigue [22.7% (17/75) vs 24.7% (18/73)], diarrhea [26.7% (20/75) vs 28.8% (21/73)], and thrombocytopenia [25.3% (19/75) vs 28.8% (21/73)]. There was no significant difference in the incidence and severity of TRAEs between the groups ( χ2=0.08, P=0.774). TACE+ DP treatment was a favorable prognostic factor for PFS ( HR=0.33, 95% CI: 0.22-0.49, P<0.001) and OS ( HR=0.19, 95% CI: 0.11-0.33, P<0.001) of patients. Conclusion:Compared to TACE combined with donafenib, TACE combined with donafenib and PD-1 inhibitors, with good efficacy and safety, significantly improved the treatment response and survival in patients with uHCC.
