Objective To investigate the effects of excessive aluminum on osteoclastic formation and function in C57BL/6 mice.Methods Six-week-old male C57BL/6 mice (n =20) were randomized by weight and divided into control group and treatment group.The mice were assigned to distilled water and 270 mg/L aluminum ion,respectively.After the 15-week treatment period,the mice were euthanized by ether asphyxiation.Concentration of serum aluminum ion was determined by inductively coupled plasma (ICP).TRAP+ cells in vivo were observed using histomorphometry and osteoclasts microstructure using electron microscope (TEM).Osteoclasts were induced by macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor κB ligand (RANKL) with bone marrow macrophages separated from femur and tibia.The expression of mRNA related with bone resorption was detected,including c-FBJ osteosarcoma oncogene (c-Fos),nuclear factor of activated T-cells cl (NFATc1),c-nonreceptor tyrosine kinase (c-Src),dentrocyte expressed seven transmembrane protein (DC-STAMP),d2 isoform of vacuolar (H1) ATPase v0 domain (ATP6v0d2) and matrix metalloproteinase 9 (MMP-9).Results The data showed that the treatment group [(12.04 ± 0.21)mg/L] had significantly increased serum aluminum ion compared with the control group [(11.00 ± 0.04)mg/L,F =10.286,P < 0.05].TRAP+ cells examination confirmed osteoclasts in treatment group [(31.39 ± 9.80) number] were significantly higher than those in the control group [(5.46 ± 4.15) number,F =9.344,P < 0.05].A large proportion of osteoclasts in treatment group lacked ruffled borders and showed vacuolation degeneration.The expression of mRNA in treatment group was lower than that of the control group.The expression of mRNA in control group and treatment group was NFATcl (3.25 ± 0.93 vs.0.29 ± 0.18,F =11.602,P < 0.05),c-Fos (0.86 ± 0.16 vs.0.16 ± 0.02,F =9.405,P < 0.05),c-Src (8.82 ± 1.51 vs.2.29 ± 0.36,F =9.128,P < 0.05),DC-STAMP (3.70 ± 0.70 vs.1.36 ± 0.57,F =10.298,P < 0.05),ATP6v0d2 (15.60 ± 4.81 vs.1.39 ± 0.95,F =8.828,P < 0.05),and MMP-9 (18.64 ± 7.62 vs.2.10 ± 0.92,F =9.356,P < 0.05),respectively.Conclusions Aluminum can increase the number of osteoclasts under epiphyseal plate,but inhibits osteoclasts differentiation.This phenomena may be related with decreased expression of c-Src,DC-STAMP,c-Fos,NFATcl,ATP6v0d2 and MMP-9 mRNA which regulate the function of osteoclasts.

Objective To investigate the application prospective of carboxyfullerene C_3 as a radioprotectant or assistant for tumor radiotherapy.Methods Different concentrations of C_3 were incubated with K562 and AHH-1 cell,CCK-8 assay and trypan blue rejection test were performed to examine the influence of C_3 on the cell viability.Annexin V/PI staining and flow cytometry assay were applied to assess the cell cycle and apoptosis after 7-ray irradiation.Results C_3 showed little toxicity to AHH-1 cell with the survival rate over 95% ,but 600 mg/L of C_3 markedly inhibited the growth of K562 cell (82%) .Pretreatment of 100 mg/L C_3 significantly increased the survival rate of AHH-1 cell after 4 Gy irradiation compared with the single radiation group(71.3% vs 90.3%) ,but decreased the apoptosis rate (26.3% vs 12.6%) ,while the survival rate of K562 cell was decreased and the apoptosis rate was elevated with the increase of C_3 concentration.Moreover,the cell cycle analysis revealed the G_2 phase block in AHH-1 cell after radiation exposure was mitigated by C_3 pretreatment,but that in K562 cell was aggravated.Conclusions C_3 has good radioprotective effects on AHH-1 cells.For K562 cell,C_3 could inhibit the cell proliferation,promote the radiation induced apoptosis and aggravate the G_2 phase block.

Methods:
The clinical and MRI data of 52 AMI patients hospitalized from January 2016 to July 2017 in our hospital were retrospectively analyzed. All patients received medication and revascularization therapies after admission and cardiac magnetic resonance examination was performed within 1 week after admission. According to whether there was LGE, AMI patients were divided into LGE(+) group(33 cases) and LGE(-) group(19 cases). According to the existence of microvascular obstruction(MVO) and/or intramyocardial hemorrhage(IMH),LGE(+) patients were divided into MVO/IMH(+) group(18 cases) and MVO/IMH(-) group(15 cases).

Pancreatic cancer,one of the common malignant tumors of the digestive system,is secretive in incidence and morbidity.Eighty percent of pancreatic cancer patients have already missed the opportunity of eradicative resection surgery when they were diagnosed,among whom,thirty to fifty percent of patients are in locally advanced tumor stage (specifically signifying the local extensive infiltration of tumor with serious vascular invasion and without distant metastasis) with a five-year survival rate of five to ten percent after excision.The pathogenesis of pancreatic cancer is still unclear,with a low rate of early diagnosis due to its lack of characteristic clinical manifestations.This paper reviewed the relevant studies on the clinical therapy of pancreatic cancer patients in locally advanced tumor stage,which is the key to improve the prognosis of pancreatic cancer.

Interpreting genes of interest is essential for identifying molecular mechanisms, but acquiring such information typically involves tedious manual retrieval. To streamline this process, the fanyi package offers tools to retrieve gene information from sources like National Center for Biotechnology Information (NCBI), significantly enhancing accessibility. Additionally, understanding the latest research advancements and sharing achievements are crucial for junior researchers. However, language barriers often restrict knowledge absorption and career development. To address these challenges, we developed the fanyi package, which leverages artificial intelligence (AI)-driven online translation services to accurately translate among multiple languages. This dual functionality allows researchers to quickly capture and comprehend information, promotes a multilingual environment, and fosters innovation in academic community. Meanwhile, the translation functions are versatile and applicable beyond biomedicine research to other domains as well. The fanyi package is freely available at https://github.com/YuLab-SMU/fanyi.

The adipose-derived stem cell exosomes are subcellular structures of adipose stem cells. They are nano-sized membrane vesicles that can transport various cell components and act on target cells by paracrine, and they play an important role in the exchanges of substance and information between cells. Scar healing is the commonest way of healing after skin tissue injury. Pathological scar can not only cause movement dysfunction, but also lead to deformity, which affects the appearance of patients and brings life and mental pressure to the patients. In recent years, many researches have shown that the adipose-derived stem cell exosomes contain a variety of bioactive molecules, which play an important role in reducing scar formation and scar-free wound healing, by affecting the proliferation and migration of fibroblasts and the composition of extracellular matrix. This article reviewed the recent literature on the roles and mechanisms of adipose-derived stem cell exosomes in scar formation, and prospected the future application and development of adipose-derived stem cell exosomes in scar treatment.

Wound healing is a complex process of biological integration in which the adverse conditions such as excessive inflammatory reactions, cell proliferation and migration disorders, and cellular secretion impairment can lead to refractory wounds. Characterized by complex etiology, protracted condition, and high morbidity and recurrence rate, refractory wounds severely impair patients′ physical and mental health. In clinical practice, refractory wounds are primarily treated with surgical debridement and skin transplantation, but there still exist problems such as large surgical wounds, prolonged recovery time, and high recurrence rate. In recent years, owing to the multipotent differentiation, immunomodulatory, and paracrine functions of stem cells, cell-assisted lipotransfer (CAL) technique, which involves intra-body injection of a mixture of autologous adipose-derived stem cells (ADSCs) and granular fat for refractory wound repair, has demonstrated promising application prospects. It is of great significance in its clinical application to clarify the mechanism of effects of CAL technique in refractory wound repair. The authors reviewed the research progress in the mechanism of effects of CAL technique in repairing refractory wounds to provide references for the research and treatment of refractory wounds.
