Sleep disorders is one of the most frequent and severe complications in patients with tinnitus and is highly correlated with the severity of tinnitus.Sleep disorders and tinnitus influence each other,forming a vicious circle.While in-terventions have been developed to alleviate tinnitus distress,these interventions are usually not effective in improving sleep in patients with tinnitus and sleep disorders.Helping tinnitus patients to resolve sleep disorders is the key to breaking the cycle and improving their quality of life.In this narrative review,we studyed the current state of research on sleep disorders in patients with tinnitus through three aspects:epidemiology,physiological and psychological mechanisms,and existing psychological,physical,and pharmacological interventions,and to provide a basis for further research on the relationship between tinnitus and sleep disorders and the precise treatment of tinnitus.

Endometriosis is a common estrogen-dependent disease in women of childbearing age,often leading to chronic pelvic pain,infertility,ovarian cancer,and other serious complications,and jeopardizing the health of women.The pathogenesis of endometriosis is complex and involves the alteration of multiple signaling pathways mediated by hormones,immunity,genetics,and the environment,and their interactions.Wnt/β-catenin signaling is involved in the regulation of embryonic development and tissue homeostasis,and it has recently been implicated in the pathogenesis of endometriosis via multiple pathways.This review considers the biological characteristics of the Wnt/β-catenin signaling pathway and summarizes the main mechanisms and signaling pathways involved in the pathogenesis of endometriosis,as well as the curr-ent research status of the regulation of this signaling pathway by traditional Chinese medicine for the treatment of endometriosis.We aim to clarify how the Wnt/β-catenin signaling pathway affects the development of endometriosis,and suggest that future studies should focus on exploring its potential role as an indicator for the clinical prediction and early diagnosis of endometriosis,thus providing theoretical support for the early diagnosis of this condition and the development of targeted drugs.

A porous composite scaffold is prepared through freeze-drying method using sodium alginate as the matrix and calcium citrate double salt as the functional enhancer.To thoroughly investigate the structure and properties of the composite scaffold,advanced instruments including Fourier transform infrared spectrometer,X-ray diffractometer,scanning electron microscope,and thermogravimetric analyzer are utilized for comprehensive structural characterization.Meanwhile,key properties such as porosity,mechanical performance,swelling ratio,gel fraction,and in vitro degradation rate are systematically tested and analyzed.The results show that the composite of sodium alginate and calcium citrate double salt is a physical complex.The porosity of the scaffold mainly ranges from 200 to 600 μm,and as the addition of double salt increases,the pore size firstly increases and then slightly decreases,while the pore distribution become more uneven.In terms of mechanical properties,with the gradual increase of the content of double salt in the scaffold,the mechanical properties of the scaffold are significantly improved.However,its swelling ratio and gel fraction exhibit decreasing trends.Additionally,the degradation rate of the alginate scaffold is relatively fast,while the addition of calcium citrate double salt does not significantly improve the degradation rate.This study not only provides valuable insights into the preparation and property research of porous composite scaffold composed of sodium alginate/calcium citrate double salt,but also offers important reference for their potential applications in biomedicine.

Objective:Vascular cell adhesion molecule 1(VCAM1)is involved in a series of physiological and pathological processes,such as immune and inflammatory response,tumor cell metastasis and invasion.But under trau-matic brain injury(TBI),specific types of cells with VC AM1 expression and the related functions are not clear.In order to further explore the specific functions of VCAM1 involved in TBI,this study constructed reporter mice of VCAM1 to explore the response of VCAM1 to TBI in detail.Methods:VCAM1-Cre/ERT2::Ai14 reporter mice were constructed by gene targeting technology and Cre/loxP system,the labeled cell types and labeling efficiency were validated by im-munofluorescence staining and reporter mice hybridization.The stab wound model was used to simulate TBI to induce the changes of VCAM1 expression in cells,and the characteristics of VCAM1 positive astrocytes were detected by immu-nofluorescence staining and fluorescent probe labeling.Results:The labeling efficiency of VCAM1-Cre/ERT2::Ai14 re-porter mice was higher than that of VCAM1 antibody as was seen by labeling of more endothelial cells of blood vessels and unique astrocytes.The distribution of these astrocytes was specific,for example in the nucleus accumbens,amygda-la,hypothalamus,and paraventricular fiber systems.TBI could significantly induce the expression of VCAM1 in astro-cytes(P＜0.0001).These induced astrocytes developed reactive qualities,including somal hypertrophy,GFAP ex-pression and proliferative ability.Conclusion:VCAM1-Cre/ERT2::Ai14 reporter mice could label cells with VCAM1 expression more sensitively,so they were more effective tools for observing expression and function of VCAM1.The up-regulation of VCAM1 expression in astrocytes after TBI surgery suggested that VCAM1 was an inflammatory response molecule in astrocytes,we recommended it as a new molecular indicator of reactive astrocytes.

Objective:To prepare a nano-barium titanate@gold Schottky junction (nano-BaTiO 3@Au) coating and investigate its effects on the adhesion, proliferation, and osteogenic differentiation of bone marrow stem cells (BMSCs), aiming to explore a titanium surface modification strategy with superior osteogenic activity. Methods:Pure titanium specimens served as the control group (Ti group). Titanium dioxide coatings were prepared on their surfaces via anodic oxidation. Nano-barium titanate (nBTO group) was further synthesized using the hydrothermal method. Gold nanoparticles were grown in situ on the nano-BaTiO 3 via high-temperature reduction of chloroauric acid using sodium citrate, yielding the nano-barium titanate@gold Schottky junction coating (nBTO@Au group). Surface morphology was observed by scanning electron microscopy (SEM). Elemental composition was analyzed using X-ray energy dispersive spectrum (EDS) and X-ray photoelectron spectroscopy (XPS). Crystal structure was analyzed using X-ray diffraction (XRD) and Raman spectroscopy. Hydrophilicity was assessed via water contact angle measurement. Specimens were co-cultured with BMSCs to evaluate biocompatibility and osteogenic properties. Cell proliferation on days 1, 3, 5, and 7 was assessed using the cell counting kit-8 (CCK-8) assay. Cytotoxicity towards BMSCs was assessed using live/dead cell staining. Cell morphology and adhesion were observed using cytoskeleton staining. Alkaline phosphatase (ALP) expression in BMSCs after 7 days was quantified using an ALP activity assay and ALP staining. Extracellular matrix mineralization after 7 days was evaluated using alizarin red staining and quantification assay. Each experiment was performed using three specimens per group. Results:Scanning electron microscopy revealed that gold nanoparticles with the diameter of(14.838±0.718) nm, uniform in size and homogeneously distributed, were successfully grown in situ on the surface of the nBTO coating. EDS and XPS confirmed the presence of Ba, Ti, O, and Au elements in the nBTO@Au composite coating. XRD and Raman spectroscopy analysis indicated that the nanostructured barium titanate (nBTO) coating was synthesized via a hydrothermal method.Water contact angle measurements showed that the contact angle was 66.8°± 0.45° for the control group, 22.55°±0.42° for the nBTO group, and 26.78°±1.15° for the nBTO@Au group, indicating good hydrophilicity of both nBTO and nBTO@Au coatings. On day 1 and day 3 of culture, the cell proliferation in the nBTO group was significantly lower than that in the control group ( P<0.05). In contrast, no significant differences were observed between the nBTO@Au group and either the control group or the nBTO group (all P>0.05). By day 5, the cell proliferation of nBTO@Au groups was significantly lower than that of the control group ( P<0.05), and the cell proliferation of nBTO group was significantly lower than that of the control group and that of the nBTO@Au group ( P<0.05). By day 7, there were no statistically significant differences in cell proliferation among all experimental groups ( F=1.62, P>0.05).Live/dead cell staining demonstrated that the cell survival rate exceeded 90% in all groups, with normal morphology and few dead cells, indicating good biocompatibility of the nBTO@Au coating. Compared to the control group, both nBTO and nBTO@Au groups promoted cell adhesion and spreading, although no significant difference in cell morphology was noted between the two modified groups. ALP staining revealed a larger stained area and deeper coloration in the nBTO@Au group. Quantitative results showed that ALP activity in the nBTO@Au group was significantly higher than that in both the nBTO and control groups ( P<0.05), and the nBTO group also exhibited significantly higher activity than the control group( P<0.05). Alizarin red staining indicated the deepest coloration in the nBTO@Au group, followed by the nBTO group, and the lightest in the control group. Quantitative analysis further confirmed that the amount of calcium nodule deposition in the nBTO@Au group was significantly greater than that in the other two groups ( P<0.05), and the nBTO group also showed significantly more deposition than the control group( P<0.05). Conclusions:This study successfully prepared an nBTO@Au coating possessing good biocompatibility and enhanced osteogenic properties.
