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 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.

Objective To prepare a dissolvable microneedle(DMN)with a tip-layer loaded with hyaluronic acid(HA)modified sinomenine hydrochloride liposomes(HA-SMH-Lip),as well as characterize,evaluate its in vitro transdermal permeability,cellular uptake ability,and anti-inflammatory ability.Methods HA-SMH-Lip-DMNs were prepared by a two-step casting method,and the drug loading capacity was determined using HPLC.The morphology,skin permeation properties and in vitro transdermal ability were investigated by scanning electron microscopy,puncture assay and Franz diffusion cell method.Fluorescent microneedles were prepared by replacing HA-SMH-Lip with fluorescein isothiocyanate liposomes(HA-FITC-Lip/FITC-Lip).The uptake behavior of inflammation cells on HA-FITC-Lip-DMNs/FITC-Lip-DMNs was investigated using a flow cytometer and a fluorescence microscope.To evaluate the anti-inflammatory activity of HA-SMH-Lip-DMNs,the levels of inflammatory factors including nitric oxide(NO),tumor necrosis factor α(TNF-α),interleukin 1β(IL-1β),and IL-10 in cell supernatants were measured using an ELISA kit.Results The prepared HA-SMH-Lip-DMNs have uniform shape and size,integral and visually pleasing array,and an average drug loading of(114.01±1.04)μg.Additionally,they have good puncture ability.The results of in vitro transdermal experiments showed that the accumulated amounts of HA-SMH-Lip-DMNs were(101.47±2.91)μg·cm-2 at 36 hours.Its transdermal ability was better than that of the SMH solution group and SMH liposome group.In vitro cellular uptake results indicated that HA-FITC-Lip-DMNs were more effectively taken up by RAW 264.7 cells(P＜0.01).Compared to the model group,HA-SMH-Lip-DMNs group significantly reduced TNF-α,IL-1β,and NO levels while increase IL-10 levels(P＜0.01).Conclusion The prepared HA-SMH-Lip-DMNs have a complete and beautiful morphology with excellent cellular uptake capability,remarkable in vitro transdermal performance,and potent anti-inflammatory properties.HA-SMH-Lip-DMNs are expected to become a new type of transdermal drug delivery system.

Objective To observe the differences in the expression levels of the hypoxia-inducible factor-1α/heme oxygenase-1/vascular endothelial growth factor A (HIF-1α/HO-1/VEGF-A) signaling pathway under different maturation outcomes of arteriovenous fistula (AVF) in patients with stage 5 chronic kidney disease, and explore the regulatory mechanism of the HIF-1α/HO-1/VEGF-A signaling pathway in the maturation process of AVF. Methods A total of 45 patients with AVF surgery for stage 5 chronic kidney disease were selected as research objects, vascular specimens were collected during the AVF surgery, and the patients were divided into AVF maturation group (n=35) and AVF poor maturation group (n=10) based on the AVF maturation outcomes within 8 weeks after surgery. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the gene expression levels of HIF-1α, HO-1 and VEGF-A in the HIF-1α/HO-1/VEGF-A signaling pathway; the Western blotting was used to detect the protein expression levels of HIF-1α, HO-1 and VEGF-A; the enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of downstream inflammatory factors such as interleukin-1β (IL-1β), interleukin-8 (IL-8), and transforming growth factor-β (TGF-β). Results The expression levels of HIF-1α mRNA, HO-1 mRNA, and VEGF-A mRNA in the AVF maturation group were significantly higher than those in the AVF poor maturation group (P < 0.01); the protein expression levels of HIF-1α, HO-1 and VEGF-A in the AVF maturation group were significantly higher than those in the AVF poor maturation group (P < 0.01); the expression levels of IL-1β, IL-8 and TGF-β in the AVF maturation group were significantly lower than those in the AVF poor maturation group (P < 0.01). Conclusion The upregulation of the HIF-1α/HO-1/VEGF-A signaling pathway is conducive to the early maturation of AVF. The measurement of the expression levels of the HIF-1α/HO-1/VEGF-A signaling pathway has a certain predictive significance for the early maturation outcome of AVF.

BackgroundThe guardianship ability of guardians of patients with severe mental disorders plays an important role in supporting the patients' recovery and reintegration into society. It is necessary to develop a scientific tool since there is a lack of tools to quantitatively assess the guardianship ability. ObjectiveTo explore and develop an assessment scale for the guardianship ability of guardians of patients with severe mental disorders， so as to provide references for the construction of scientific and reasonable guardianship ability evaluation tools. MethodsA pool of scale items was constructed through a literature review and interviews， followed by two rounds of expert consultation with 15 specialists. 364 guardians of patients with severe mental disorders in Guangzhou were investigated. The scale items were screened and optimized using item analysis and exploratory factor analysis， and the structural validity of the scale was further verified through confirmatory factor analysis. The content validity of the scale was evaluated by item-level content validity index （I-CVI） the average scale-level content validity index （S-CVI/Ave）. The reliability of the scale was tested by Cronbach's α coefficient and split-half reliability. ResultsThe guardianship ability scale for guardians of patients with severe mental disorders consists of 25 items， including three dimensions of guardianship willingness， guardianship knowledge and behavior and guardianship self-efficacy. The results of the item analysis showed that all items met the corresponding criteria and were retained. Validity test： the I-CVI ranged from 0.800 to 1.000， and the S-CVI/Ave was 0.964. Factor load of each item on the corresponding factors ranged from 0.596 to 0.976， and the model demonstrated good fit： chi-square degree of freedom ratio （χ²/df） was 2.444， Tucker-Lewis index （TLI） was 0.908， comparative goodness of fit index （CFI） was 0.917， standardized root mean square residual （SRMR） was 0.049， and root mean square residual （RMSEA） was 0.089. Reliability test showed that the total scale had a Cronbach's α coefficient of 0.966， and the split half reliability coefficient was 0.915.

Objective:To explore the association between child abuse and suicidal ideation in patients with bi-polar disorder.The mediation of self-esteem and depression in this association was also investigated.Methods:A to-tal of 292 patients with bipolar disorder who met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)were enrolled.Their child abuse,suicidal ideation,self-esteem,depres-sion,and mania were assessed with the Childhood Trauma Questionnaire(CTQ),Beck Scale for Suicide Ideation-Chinese Version(BSICV),Self-Esteem Scale(SES),17-item Hamilton Depression Rating Scale(HAMD-17)and Young Mania Rating Scale(YMRS).The mediating effects were evaluated using PROCESS for SPSS.Results:The BSICV scores were positively associated with the scores of CTQ(r=0.37,P＜0.01)and HAMD-17(r=0.53,P＜0.01)and negatively associated with SES scores(r=-0.50,P＜0.01)in patients with bipolar disorder.Self-esteem and depression played mediating roles between child abuse and suicidal ideation,respectively(95％CI:0.01-0.09,0.01-0.10).Besides,self-esteem and depression sequentially mediated the relationship between child a-buse and suicidal ideation(95％CI:0.02-0.06).Conclusion:Child abuse,low self-esteem,and depression may be related factors of suicidal ideation in patients with bipolar disorder.

The stenosis and embolization of internal fistula vessels directly affect the clinical treatment effect of maintenance hemodialysis patients, and the study of the mechanism of internal fistula stenosis has become a research hotspot in recent years. Previous studies mainly focused on the hemodynamics and pathophysiology of blood vessel wall, and there were few studies on molecular biology and its related signaling pathways. This paper reviews the hemodynamics of the vascular pathway of internal arteriovenous fistula (AVF), the pathophysiological mechanism, molecular biology, and changes in various signaling pathways of AVF dysfunction at home and abroad, in order to provide references for the study of AVF dysfunction.

Background and Aims:There is currently no consensus on whether the pancreaticoduodenectomy with Heidelberg triangle operation(PDTRIANGLE)or the standard radical pancreaticoduodenectomy(PDSTANDARD)is more beneficial for patients with pancreatic cancer,and no large-scale multicenter studies have confirmed this.Therefore,this study was conducted to compare the clinical efficacy and safety of PDTRIANGLE and PDSTANDARD for treating pancreatic cancer through a Meta-analysis. Methods:Relevant literature comparing the two surgical approaches comparing the two surgical approaches for treating pancreatic cancer was screened from Chinese and English databases based on inclusion criteria.The search timeframe extended from the inception of the databases to May 2024,and Review Manager 5.3 software was used for Meta-analysis of the extracted outcome variables. Results:A total of 6 retrospective studies were included,comprising 658 patients,with 315 in the PDTRIANGLE group and 343 in the PDSTANDARD group.The Meta-analysis results showed that the operative time in the PDTRIANGLE group was longer than that in the PDSTANDARD group(OR=1.52,95％CI=0.42-2.61,P=0.007),the lymph node dissection rate was higher in the PDTRIANGLE group(OR=0.70,95％CI=-0.4-1.01,P＜0.000 01),and the R0 resection rate was also higher in the PDTRIANGLE group(OR=1.63,95％CI=1.03-2.58,P=0.04).The incidence rates of postoperative lymphatic fistula and diarrhea were higher in the PDTRIANGLE group compared to the PDSTANDARD group(OR=5.60,95％CI=1.81-17.29,P=0.003;OR=0.13,95％CI=0.07-0.20,P＜0.000 1).The length of hospital stay was longer in the PDTRIANGLE group(OR=0.40;95％CI=-0.14-0.65,P=0.003).The overall survival rates at 1 and 2 years were significantly better in the PDTRIANGLE group compared to the PDSTANDARD group(OR=2.19,95％CI=-1.27-3.76,P=0.005;OR=1.65,95％CI=-1.01-2.67,P=0.04),and the 1-year disease-free survival rate was also significantly higher in the PDTRIANGLE group(OR=3.71,95％CI=2.27-6.07,P＜0.000 01),although the difference in the 2-year disease-free survival rate between the two groups was not statistically significant(OR=2.63,95％CI=-0.91-7.59,P=0.07). Conclusion:PDTRIANGLE is a safe and effective treatment for pancreatic cancer.Compared to PDSTANDARD,PDTRIANGLE significantly improves the R0 resection rate,thereby enhancing the postoperative disease-free survival rate and achieving a better long-term prognosis.

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.
