ObjectiveTo observe the clinical effectiveness of horticultural therapy involving the planting of Chinese medicinal herbs （mint and lily potted plants） combined with intradermal needling therapy for generalized anxiety disorder （GAD） of liver depression transforming into fire syndrome under transcranial magnetic stimulation and basic psychological therapy， and to explore the possible mechanisms of action. MethodsA total of 180 patients with GAD of liver depression transforming into fire syndrome were randomly divided into three groups， horticultural therapy group， intradermal needling group， and horticultural therapy+intradermal needling group， with 60 patients in each. All groups received basic treatment including basic psychological therapy and transcranial magnetic stimulation. The horticultural therapy group received horticultural therapy in addition to the basic treatment； the intradermal needling group received intradermal needling therapy once a week for 8 weeks in addition to the basic treatment； the horticultural therapy+intradermal needling group received both horticultural therapy and intradermal needling therapy， following the same procedures and duration. Hamilton Anxiety Rating Scale （HAMA）， Self-Rating Anxiety Scale （SAS）， and Pittsburgh Sleep Quality Index （PSQI） scores were assessed at baseline and after 2， 4， 6， and 8 weeks of treatment. Serum levels of adrenocorticotropic hormone （ACTH） and corticosterone （CORT） were measured before treatment and after 8 weeks of treatment. Motor-evoked potential （MEP） baseline levels were recorded before treatment， and MEP amplitude ratios were compared after 1 week and 8 weeks of treatment. Clinical effectiveness and safety were evaluated after 8 weeks of treatment. Pearson correlation analysis was used to examine the relationships between serum ACTH and CORT levels， MEP amplitude， and anxiety. ResultsIn the horticultural therapy group and intradermal needling group， HAMA， SAS and PSQI scores after 4， 6， and 8 weeks treatment were lower than baseline scores （P＜0.05）. In the horticultural therapy+intradermal needling group， these scores showed a significant decline starting after 2 weeks treatment and continuing through 8 weeks after treatment （P＜0.05）. The HAMA， SAS， and PSQI scores in the horticultural therapy+intradermal needling group were significantly lower than those in the other two groups after 2， 4， 6， and 8 weeks treatment （P＜0.05）. After 8 weeks of treatment， serum CORT and ACTH levels in the horticultural therapy+intradermal needling group were significantly lower than baseline levels （P＜0.05） and were also lower than those in the horticultural therapy group and intradermal needling group at the same time point （P＜0.01）. When comparing the level after 8 weeks treatment to that after 1 week treatment， under PAS10 stimulation， the MEP amplitude ratio in the intradermal needling group decreased at 30 minutes， while in the horticultural therapy+intradermal needling group， the MEP amplitude ratio decreased at all time points （P＜0.05 or P＜0.001）； under PAS25 stimulation， the MEP amplitude ratio in the horticultural therapy group increased at 20 minutes， and in the intradermal needle group at 10 minutes （P＜0.05）. In the horticultural therapy+intradermal needling group， the MEP amplitude ratio increased significantly at all time points after treatment （P＜0.001）. The cure rate in the horticultural therapy+intradermal needling group （74.14%， 43/58） was significantly higher than that in the horticultural therapy group （30.00%， 18/60） and the intradermal needling group （48.28%， 28/58， P＜0.05）. Correlation analysis revealed that serum ACTH and CORT levels were positively correlated with HAMA scores （r = 0.488， P＜0.01； r = 0.428， P＜0.01）. Following PAS10 intervention， the MEP amplitude ratio was positively correlated with HAMA scores （r = 0.458， P＜0.01）， whereas after PAS25 intervention， the MEP amplitude ratio was negatively correlated with HAMA scores （r = -0.562， P＜0.01）. ConclusionHorticultural therapy combined with intradermal needling treatment， under transcranial magnetic stimulation and basic psychological therapy， demonstrates significant clinical effectiveness in patients with GAD of liver depression transforming into fire syndrome. Its mechanism of action may be related to the regulation of hyperactivation of the hypothalamic-pituitary-adrenal （HPA） axis and the reduction of cortical excitability.

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.

Objective:This study investigated the expression of C-X-C motif chemokine receptor 3 (CXCR3) on CD45RO? T cells in the peripheral blood of patients with Alzheimer′s disease (AD) and its association with clinical features.Methods:A total of 41 AD patients and 30 age-and sex-matched healthy controls (HCs) were recruited from the Department of Neurology at the Medical Division of PLA General Hospital between September 2022 and March 2024. Flow cytometry was used to quantify CXCR3 expression on CD45RO? T cell subsets in peripheral blood. Dementia severity in AD patients was assessed using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). Spearman correlation analysis examined the relationship between CD45RO?CXCR3? T cell levels and cognitive function in the AD group. Receiver operating characteristic (ROC) curve analysis determined the predictive utility of CD45RO?CXCR3? T cells for AD, quantified by the area under the curve (AUC).Results:Compared to healthy controls, AD patients exhibited significantly elevated levels of CD8?CD45RO?CXCR3? T cells [17.8% (7.2%, 40.3%) vs. 8.2% (5.1%, 12.3%), Z=-2.59, P<0.05]. However, no significant differences were observed for CD4?CD45RO?CXCR3? T cells, CD4?CD45RO?CXCR3? T cells, or CD8?CD45RO?CXCR3? T cells ( P>0.05). Spearman correlation analysis revealed a negative correlation between CD8?CD45RO?CXCR3? T cell levels and cognitive scores (MMSE: r=-0.72, P<0.05; MoCA: r=-0.70, P<0.05). ROC analysis demonstrated an AUC of 0.81 for CD8?CD45RO?CXCR3? T cells in predicting AD, with a sensitivity of 59.0% and specificity of 93.3%. Conclusions:CXCR3 expression is significantly upregulated on CD8?CD45RO? T cells in AD patients, and its levels correlate with cognitive impairment severity. These findings suggest that CD8?CD45RO?CXCR3? T cells may serve as a potential biomarker for AD diagnosis and progression monitoring.

OBJECTIVE: This study aims to elucidate the therapeutic potential of osthole for the treatment of atopic dermatitis (AD), focusing on its ability to alleviate chronic pruritus (CP) and the underlying molecular mechanisms. METHODS: In this study, we investigated the anti-inflammatory effects of osthole in both a 2,4-dichloronitrobenzene (DNCB)-induced AD mouse model and tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) stimulated huma immortalized epidermal (HaCaT) cells. The anti-itch effect of osthole was specifically assessed in the AD mouse model. Using methods such as hematoxylin and eosin (HE) staining, enzyme-linked immunosorbent assay (ELISA), western blot (WB), quantitative real-time PCR (qRT-PCR), and immunofluorescence staining. RESULTS: Osthole improved skin damage and clinical dermatitis scores, reduced scratching bouts, and decreased epidermal thickness AD-like mice. It also reduced the levels of interleukin (IL)-31 and IL-31 receptor A (IL-31 RA) in both skin tissues and HaCaT cells. Furthermore, Osthole suppressed the protein expression levels of phosphor-p65 (p-p65) and phosphor-inhibitor of nuclear factor kappa-Bα (p-IκBα). Meanwhile, it increased the protein expression levels of peroxisome proliferator-activated receptor α (PPARα) and PPARγ in HaCaT cells. CONCLUSION These findings indicated that osthole effectively inhibited CP in AD by activating PPARα, PPARγ, repressing the NF-κB signaling pathway, as well as the expression of IL-31 and IL-31 RA.

Objective To explore the pathogenesis of cesarean scar pregnancy(CSP)by detecting the ex-pression of transforming growth factor β1(TGF-β1),vascular endothelial growth factor(VEGF),and connec-tive tissue growth factor(CTGF)the decidua tissue of cesarean scar and the decidual tissue of uterine cavity of CSP,and the decidua tissue of cesarean scar and the decidual tissue of uterine cavity of normal pregnancy after cesarean section.Methods Decidual tissues of totally 120 cases of CSP group and 120 cases of normal preg-nancy group after induced abortion at the Department of Obstetrics and Gynecology in Guizhou Medical Uni-versity Affiliated Hospital were collected.The expression of TGF-β1,CTGF,and TGF and VEGF in decidual tissue was detected using immunohistochemistry.Results The expression of TGF-β1 and CTGF in the decid-ual tissue of cesarean scar in the CSP group was higher than that in the decidual tissue of uterine cavity in the CSP group and the decidua tissue of cesarean scar in the normal pregnancy group,and the differences were sta-tistically significant(P＜0.05).The expression of VEGF the decidua tissue of cesarean scar in the CSP group was not significantly different from that in the decidual tissue of uterine cavity in the CSP group and the decid-ua tissue of cesarean scar in the normal pregnancy group(P＞0.05).TGF-β1 in the decidual tissue was posi-tively correlated with CTGF(r=0.910,P＜0.05),and TGF-β1 and VEGF had no correlation(r=-0.032,P＞0.05).Conclusion The high expression of TGF-β1 and CTGF in decidual tissue of cesarean scar of CSP may be a high risk factor for CSP,and measures should be taken to inhibit the production of TGF-β1 and CT-GF in cesarean scar,so as to open up a new way to prevent the occurrence of CSP.

Objective:To study and screen the differential expression of inflammatory proteins in diabetes skin ulcers and common skin ulcers, so as to provide experimental basis for further research on anti-inflammatory and healing drug targets of diabetes skin ulcers.Methods:The tissues of 11 patients with diabetes skin ulcer, 12 patients with common skin ulcer and 11 patients with normal skin were collected from the First Hospital of Hunan University of Chinese Medicine. The levels of inflammatory protein Toll like receptor 4 (TLR4), nuclear factor κB (NF-κB), pro-inflammatory factor interferon -γ (IFN -γ), tumor necrosis factor - α (TNF -α), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-1β (IL-1β), macrophage chemotactic protein-1 (MCP-1), anti-inflammatory factors epidermal growth factor (EGF), interleukin-4 (IL-4), and interleukin-10 (IL-10) were detected in three groups of tissues using enzyme-linked immunosorbent assay (ELISA).Results:Compared with normal tissues, the concentrations of TLR4, NF-κB, IFN -γ, TNF -α, IL-1β, IL-6, IL-8, MCP-1 and EGF in common ulcer skin tissues and diabetes ulcer tissues were higher, and the concentrations of IL-10 were lower, with statistically significant differences (all P<0.05); Compared with the normal tissue, the concentration of IL-4 in diabetes ulcer tissue was lower, the difference was statistically significant ( P<0.05); Compared with ordinary ulcer skin tissue, the concentrations of TLR4, NF-κB and MCP-1 in diabetes ulcer tissue were higher, and the concentrations of IL-4 were lower, with statistically significant differences (all P<0.05). Conclusions:The skin ulcer in diabetes patients will have inflammatory reaction, and high glucose promotes the inflammatory reaction of skin ulcer, which may be related to the abnormal expression of TLR4, NF-κB, MCP-1 and IL-4. TLR4/NF-κB signal pathway and inflammatory factors MCP-1 and IL-4 may be the target of the inflammation regulation of diabetes skin ulcer.
