Objective To investigate the effects of music therapy on cognitive function and immunity of sleep-deprived mice and the potential underlying mechanisms.Methods A novel music therapy was developed by integrating elements from both Western and Chinese music.A sleep-deprived mouse model was established to explore the effects of the music combination on learning and memory of mice using Morris water maze experiments.ELISA was used to detect immune-endocrine indicators in the blood and saliva of mice and to study the effects of this music combination on IgA levels.Transcriptome high-throughput sequencing and B-cell receptor(BCR)repertoire sequencing were adopted to explore the potential mechanisms through which music therapy influenced IgA production.Results The Morris water maze test revealed that the novel music therapy could promote the recovery of cognition and memory of sleep-deprived mice.Additionally,it was found that the music combination could increase IgA levels in both blood and saliva.Transcriptome high-throughput sequencing and BCR sequencing analysis showed that the music combination enhanced the abundance of the IgA immunoglobulin light chain variable region(Igkv4-53)and heavy chain constant region(Igha).Conclusion Music therapy can help restore cognitive function and increase IgA levels in sleep-deprived mice.The mechanism may be related to the enhanced abundance of immunoglobulin light chain variable region(Igkv4-53)and heavy chain constant region(Igha).

Objective:To prepare hydroxyapatite(HA)coating on polyether ether ketone(PEEK)surface by magnetron sputtering technique and to study its biosafety.Methods:Sulfonated PEEK was used to increase the binding area and HA coating was constructed on it using magnetron sputtering technology.SEM and energy dispersive spectroscopy(EDAX)were used to detect the construction effect.Cell adhesion assay,cytoskeletal fluorescence staining and SEM validation were used to assess cytologrcal safety.In vivo safety tests were conducted in SD rats and golden hamsters.Results:HA coating with gradient morphology was successfully constructed on the PEEK surface using above technique.The coating promoted cell adhesion,extension and proliferation.No systemic toxicity and no sig-nificant influence in HE staining of the main infernal organs samples were observed.The coating alleviated the oral mucosal irritation caused by simple sulfonation to a certain extent.Conclusion:HA coating can be prepared stably with magnetron sputtering technology and can meet the biosafety needs for clinical applications.

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.

ObjectiveTo investigate the tumor-suppressing effect of Shenqi Yiliu prescription combined with cisplatin in hepatoma H22-bearing mice based on the phosphatase and tensin homolog deleted on chromosome ten (PTEN)/phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt) pathway. MethodH22-bearing mice were prepared and randomized into model group, cisplatin group, and cisplatin combined with high-, medium-, and low-dose Shenqi Yiliu prescription groups, with 10 mice in each group. Another 10 healthy mice were randomly selected as normal group. Shenqi Yiliu prescription was given by gavage with the high, medium, low dose of 54.06, 27.03, 13.515 g·kg-1·d-1, respectively, and cisplatin (2.5 mg·kg-1) was administered by intraperitoneal injection, twice a week. Normal group and model group received normal saline. After 13 days of treatment, mice were killed and the tumor inhibition rate was calculated. The pathomorphological changes of tumor were observed based on hematoxylin-eosin (HE) staining, and enzyme-linked immunosorbent assay (ELISA) and immunofluorescence method were used to detect the content of cyclin-dependent kinase inhibitor 1A (p21) and cyclin-dependent kinase inhibitor 1B (p27) in tumor tissue of mice. The levels of PTEN, PI3K and phosphorylated protein kinase B (p-Akt) in tumor tissue were measured by Western blot. ResultCompared with the model group, cisplatin alone and cisplatin in combination with the high-, medium-, and low-dose Shenqi Yiliu prescription decreased tumor mass (P<0.05), particularly the cisplatin in combination with the high-dose Shenqi Yiliu prescription. Necrosis of the tumor tissue was observed in each group, especially the cisplatin combined with high-dose Shenqi Yiliu prescription group. As compared with the model group, cisplatin alone and cisplatin in combination with the high-, medium-, and low-dose Shenqi Yiliu prescription raised the expression of p21, p27, and PTEN (P<0.05) and lowered the expression of PI3K and p-Akt (P<0.05), particularly the cisplatin in combination with high-dose Shenqi Yiliu prescription. ConclusionShenqi Yiliu prescription may regulate the expression of key molecules in PTEN/PI3K/Akt signaling pathway, thereby upregulating the expression of downstream proliferation inhibitors p21 and p27, further suppressing the tumor in H22-bearing mice, and enhancing the effect of chemotherapy.

Objective:To study the efficacy of low-intensity focused ultrasound (LIFU) on neuropathic pain (NP) in mice, and its effect on the activation of astrocytes and the expression of pro-inflammatory cytokines were discussed.Methods:Thirty-six male C57BL/6J mice were randomly divided into three groups: sham operation (Sham) group and chroinc constriction injury (CCI) model group and treatment (CCI+ LIFU) group, 12 mice in each group.NP model was established by CCI on the sciatic nerve. The group of CCI+ LIFU received LIFU treatment for the anterior cingulate cortex (ACC) on the 7th day after surgery, the mechanical withdrawal threshold (MWT) on the affected side of mice was measured at preoperation 3, 6, 12, 18, 24, and 27 days after operation, respectively, H&E staining was used to observe pathological morphological changes in the ACC region, the expression levels of ACC region AQP4 and GFAP protein were detected by Western Blot and immunofluorescence, and the expression levels of ACC region pro-inflammatory cytokines IL-1β and TNF-α were detected by enzyme-linked immunosorption assay.Results:Compared with Sham group, MWT in the CCI group decreased from the 3rd day until the 27th day after surgery( P<0.05); Compared with the CCI group, the MWT in the CCI+ LIFU group increased on the 24th day after surgery, and was significantly higher than that of the CCI group on the 24th and 27th day after surgery ( P<0.05); LIFU stimulation did not produce significant pathological changes in the ACC region; Western Blot and immunofluorescence showed that AQP4 and GFAP protein expression in the ACC region were upregulated ( P<0.05) after peripheral nerve injury, while AQP4 and GFAP protein expression was downregulated after LIFU treatment ( P<0.05); Enzyme-linked immunosorbents showed that the expression of pro-inflammatory cytokines IL-1β and TNF-α in the region of ACC was upregulated ( P<0.05) after peripheral nerve injury, while the expression of IL-1β and TNF-α was downregulated after LIFU treatment ( P<0.05). Conclusions:LIFU can effectively relieve mechanical pain sensitivity symptoms in mice induced by CCI, possibly by inhibiting activation of astrocytes and neuro-inflammatory responses.

Objective: To study the role of activating transcription factor 2 (ATF-2) in the growth of mandibular condyle cartilage. Methods: Primary chondrocytes of condyle were cultured. Expression plasmid of ATF-2 and plasmid bcl-2 promoter were transfected into chondrocytes. Luciferase assay and Western blot were used. Results: The absence of ATF-2 in mandibular condyle chondrocytes resulted in a decline in bcl-2 promoter activity, reduction in bcl-2 protein level. Conclusion: The results strongly imply that ATF-2 is required for adequate bcl-2 expression, and play a significant role in controlling growth plate chondrocyte progression.
