OBJECTIVE To investigate the targeting effect of folic acid-modified crebanine nanoparticles (FA-Cre@PEG- PLGA NPs, hereinafter referred to as “NPs”) combined with ultrasound irradiation on M109 cells in vitro and in vivo after administration, and explore the anti-tumor mechanism. METHODS CCK-8 assay was used to detect the inhibitory effect of NPs combined with ultrasound irradiation on the proliferation of M109 cells, and the best ultrasound time was selected. Using human lung cancer A549 cells as a control, the targeting of NPs combined with ultrasound irradiation to M109 cells was evaluated by free folic acid blocking assay and cell uptake assay. The effects of NPs combined with ultrasound irradiation on the migration, invasion, apoptosis, cell cycle and reactive oxygen species (ROS) levels of M109 cells were detected by cell scratch test, Transwell chamber test and flow cytometry at 1 h after 958401536@qq.com administration; the changes of mitochondrial membrane potential (MMP) were observed by fluorescence inverted microscope. A mouse subcutaneous tumor model of M109 cells was constructed, and the in vivo tumor targeting of NPs combined with ultrasound irradiation was investigated by small animal in vivo imaging technology. RESULTS NPs combined with ultrasound irradiation could significantly inhibit the proliferation of M109 cells, and the optimal ultrasound time was 1 h after administration. The free folic acid could antagonize the inhibitory effect of NPs on the proliferation of M109 cells, and combined with ultrasound irradiation could partially reverse this antagonism. Compared with A549 cells, the uptake rate of NPs in M109 cells was significantly higher (P<0.01), and ultrasound irradiation could promote cellular uptake. NPs combined with ultrasound irradiation could inhibit the migration and invasion of M109 cells and block the cell cycle in the G0/G1 and G2/M phases. Compared with control group, the apoptosis rate of M109 cells and ROS level were increased significantly (P<0.01), while the MMP decreased significantly (P<0.01) in the different concentration (100, 200, 300 μg/mL) groups of M109 cells. Compared with the mice in non-ultrasound group, the fluorescence intensity and tumor-targeting index of the tumor site in the 0 h ultrasound group were significantly enhanced (P<0.05 or P<0.01). CONCLUSIONS NPs combined with ultrasound irradiation have a strong targeting effect on M109 cells in vitro and in vivo, the anti-tumor mechanism includes inhibiting cell migration and invasion, blocking cell cycle, and inducing apoptosis.

Depression is increasingly prevalent among adolescents and can profoundly impact their lives. However, the early detection of depression is often hindered by the time-consuming diagnostic process and the absence of objective biomarkers. In this study, we propose a novel approach for depression detection based on an affective brain-computer interface (aBCI) and the resting-state electroencephalogram (EEG). By fusing EEG features associated with both emotional and resting states, our method captures comprehensive depression-related information. The final depression detection model, derived through decision fusion with multiple independent models, further enhances detection efficacy. Our experiments involved 40 adolescents with depression and 40 matched controls. The proposed model achieved an accuracy of 86.54% on cross-validation and 88.20% on the independent test set, demonstrating the efficiency of multimodal fusion. In addition, further analysis revealed distinct brain activity patterns between the two groups across different modalities. These findings hold promise for new directions in depression detection and intervention.

Two novel skeleton sesquiterpenoids (1 and 6), along with four new iphionane-type sesquiterpenes (2-5) and six new cyperane-type sesquiterpenes (7-11), were isolated from the whole plant of Artemisia hedinii (A. hedinii). The two novel skeleton compounds (1 and 6) were derived from the decarbonization of iphionane and cyperane-type sesquiterpenes, respectively. Their structures were elucidated through a comprehensive analysis of spectroscopic data, including high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) and 1D and 2D nuclear magnetic resonance (NMR) spectra. The absolute configurations were determined using electronic circular dichroism (ECD) spectra, single-crystal X-ray crystallographic analyses, time-dependent density functional theory (TDDFT) ECD calculation, density functional theory (DFT) NMR calculations, and biomimetic syntheses. The biomimetic syntheses of the two novel skeletons (1 and 6) were inspired by potential biogenetic pathways, utilizing a predominant eudesmane-type sesquiterpene (A) in A. hedinii as the substrate. All compounds were evaluated in LX-2 cells for their anti-hepatic fibrosis activity. Compounds 2, 8, and 10 exhibited significant activity in downregulating the expression of α-smooth muscle actin (α-SMA), a protein involved in hepatic fibrosis.

Objective:
To investigate the effects of β-caryophyllene(BCP) on the browning of white adipose tissue in obese mice and the related mechanisms.
Methods:
An obese mouse model was establishedviaintraperitoneal injection of a high-fat diet supplemented with propylthiouracil saline solution [14.4 mg/(kg·d)] in male Kunming mice. Obesity model mice were randomly divided into a model group(Model group) and a BCP administration group(BCP-50 group); normal diet mice were set up as a control group(Control group), with 8 mice in each group. BCP administration was given by gavage at a dose of 50 mg/kg once in the morning and once in the evening in the BCP-administered group, while the rest of the group was administered by gavage with aqueous solution of Tween 80 for 4 weeks. The oral glucose tolerance test was performed at the end of 4-week administration, and mice were executed after overnight fasting at the end of the experiment, and blood samples and adipose tissues were rapidly collected for subsequent experimental tests. The kit was used to detect serological-related indexes; hematoxylin-eosin staining was conducted to observe the morphology of adipose tissue; immunohistochemical staining was carried out to observe the expression of uncoupling protein 1(UCP1) in adipose tissue; Western blot was employed to detect expression of peroxisome proliferator-activated receptor γ coactivator1-α(PGC1α), peroxisome proliferator-activated receptor γ(PPARγ), UCP1 and cannabinoid receptor 2(CNR2) proteins in epididymal white adipose(eWAT).
Results:
Compared with the model group, the body mass of obese mice in the BCP-50 group was significantly reduced(P<0.05), food intake was decreased(P<0.01), insulin resistance was improved(P<0.000 1), and the serum content of low-density lipoprotein cholesterol(LDL-C) and nonesterified fatty acid(NEFA) in the obese mice was significantly reduced(P<0.000 1 andP<0.01). Total cholesterol(TC), triglyceride(TG), and high-density lipoprotein cholesterol(HDL-C) contents did not change significantly. In addition, the adiposity coefficient and eWAT specific gravity of obese mice in the BCP-50 group were significantly decreased(P<0.05); the adipocytes in eWAT and BAT were reduced; and the expression of the UCP1 protein was significantly elevated(P<0.01 andP<0.05). In addition to UCP1, the expression levels of PGC1α, PPARγ, and CNR2 proteins in the eWAT of obese mice in the BCP-50 group were also significantly elevated(P<0.01,P<0.05, andP<0.001).
Conclusion
β-caryophyllene promotes white adipose tissue browning through up-regulating PPARγ/PGC-1α/UCP1 pathway expression, thus improving obesity.
