ObjectiveTo investigate the mechanism of action of modified Shaofu Zhuyutang in antagonizing cellular pyroptosis and fibrosis in ectopic endometrial tissues of endometriosis through the Toll-like receptor 4/nuclear factor-κB/NOD-like receptor protein 3 (TRL4/NF-κB/NLPR3) signaling pathway. MethodsSeventy-two SPF-grade female SD rats were randomly divided into a sham-operated group (n = 12) and a modeling group (n = 60). The rats in the sham-operated group underwent a caesarean section, while the rats in the modeling group were used to establish an endometriosis model through the auto-transplantation method. After successful modeling, the animals were randomly divided into the model group, progesterone group (0.25 mg·kg-1), and modified Shaofu Zhuyutang low-, medium-, and high-dose groups (7.5, 15, 30 g·kg-1), with 12 animals in each group. After 4 weeks of drug administration, voluntary activity and heat pain latency were observed. The rats were sacrificed for tissue collection, and Masson staining were used to observe histopathological changes in the endometrial tissues. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of interleukin-18 (IL-18), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and transforming growth factor-β (TGF-β). Immunohistochemistry (IHC) was used to detect the protein expression area of tumor necrosis factor-related factor 6 (TRAF6) and NLPR3 in the endometrial tissues. Immunofluorescence (IF) was used to detect the relative fluorescence intensity of Caspase-1 and gasdermin D (GSDMD) in the endometrial tissues. Western blot was employed to measure the relative expression of TRL4, myeloid differentiation factor 88 (MyD88), TRAF6, NF-κB p65, phosphorylated NF-κB p65 (p-NF-κB p65), and NLPR3 proteins in endometrial tissues. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of TRL4, MyD88, TRAF6, NF-κB, and NLPR3 in the endometrial tissues. ResultsCompared with the sham-operated group, rats in the model group showed reduced voluntary activity and shorter heat pain latency. Serum levels of IL-18, IL-1β, TNF-α, and TGF-β were elevated. The relative expression areas of TRAF6 and NLPR3 proteins were increased, and the relative fluorescence intensity of Caspase-1 and GSDMD was enhanced. The relative expression of TRL4, MyD88, TRAF6, NF-κB p65, p-NF-κB p65, and NLPR3 proteins, along with the expression of TRL4, MyD88, TRAF6, NF-κB, and NLPR3 mRNA, were significantly increased (P<0.01). Compared with the model group, rats in the progesterone group and the modified Shaofu Zhuyutang medium- and high-dose groups exhibited improved voluntary activity, longer heat pain latency, the fibrosis of endometrial tissue is alleviated. Serum levels of IL-18, IL-1β, TNF-α, and TGF-β were decreased. The relative expression areas of TRAF6 and NLPR3 proteins decreased, and the relative fluorescence intensity of Caspase-1 and GSDMD weakened. The relative expression of TRL4, MyD88, TRAF6, p-NF-κB p65, NLPR3 proteins, and TRL4, MyD88, TRAF6, NF-κB, and NLPR3 mRNA expression were reduced (P<0.05, P<0.01). ConclusionModified Shaofu Zhuyutang may play a therapeutic role in endometriosis by interfering with key proteins in the TRL4/NF-κB/NLPR3 signaling pathway, reducing NLRP3 inflammasome-induced cellular pyroptosis, antagonizing the fibrosis process in ectopic endometrial tissues, improving the inflammatory microenvironment in the pelvic cavity, and alleviating pain.

ObjectiveTo observe the effects of modified Shaofu Zhuyutang on key proteins of the epidermal growth factor receptor (EGFR)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway in SD rats with endometriosis. MethodsAfter successful establishment of an endometriosis model in 60 female SD rats of SPF grade via the auto-transplantation method, the rats were randomly divided into a model group, modified Shaofu Zhuyutang high-, medium-, and low-dose groups, and a gestrinone group, with another 12 rats serving as a blank group. The blank and model groups were administered 10 mL·kg-1 normal saline, while the high-, medium-, and low-dose groups received 30, 15, and 7.5 g·kg-1 modified Shaofu Zhuyutang, respectively. The gestrinone group was administered 0.25 mg·kg-1 gestrinone suspension. After four weeks of treatment, uterine contractions were induced with 2 U of oxytocin, and the writhing response of rats was observed. After 24 h, the rats were euthanized, and the weight and volume of ectopic endometrial tissue were recorded. Hematoxylin-eosin (HE) staining was used to observe pathological changes in endometrial tissues, while the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay was used to evaluate the apoptosis rate of endometrial tissues. Immunofluorescence was used to detect the relative expression areas of the B-cell lymphoma-2 gene-associated promoter (Bad) and B-cell lymphoma-2 (Bcl-2) proteins in endometrial tissues. Serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), epidermal growth factor (EGF), and EGFR were measured by enzyme-linked immunosorbent assay (ELISA). The relative protein expression levels of EGFR, PI3K, phosphorylated PI3K (p-PI3K), Akt, and phosphorylated Akt (p-Akt) in endometrial tissues were analyzed by Western blot. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression levels of EGFR, PI3K, and Akt. ResultsCompared with the blank group, the model group showed endometrial thickening, glandular and mesenchymal hyperplasia, a significant decrease in the relative expression area of Bad in ectopic endometrial tissues, a significant increase in the relative expression area of Bcl-2, and a significant reduction in the apoptosis rate as indicated by TUNEL staining. Serum levels of IL-1β, IL-6, TNF-α, EGF, and EGFR were significantly elevated (P<0.01). The relative protein expression levels of EGFR, PI3K, p-PI3K, Akt, and p-Akt, as well as the mRNA expression levels of EGFR, PI3K, and Akt, were also significantly increased (P<0.01). Compared with the model group, the high- and medium-dose groups of modified Shaofu Zhuyutang and the gestrinone group exhibited reduced glandular and mesenchymal hyperplasia to varying degrees, with dilated glandular lumens. The number of writhing responses was significantly reduced, the latency to writhing response was significantly prolonged, and the weight and volume of ectopic endometrial tissue were significantly decreased. The relative expression area of Bad in ectopic endometrial tissue was significantly increased, the relative expression area of Bcl-2 was significantly decreased, and the apoptosis rate was significantly elevated as shown by TUNEL staining. Serum levels of IL-1β, IL-6, TNF-α, EGF, and EGFR were significantly reduced, and the relative protein expression levels of EGFR, PI3K, p-PI3K, Akt, and p-Akt, as well as the mRNA expression levels of EGFR, PI3K, and Akt, were significantly decreased (P<0.05,P<0.01). ConclusionModified Shaofu Zhuyutang may exert therapeutic effects on endometriosis by interfering with key proteins of the EGFR/PI3K/Akt signaling pathway and inducing apoptosis in ectopic endometrial tissue.

ObjectiveTo investigate the mechanism of modified Shaofu Zhuyutang in inducing ferroptosis in ectopic endometrial tissues of rats with endometriosis through the murine double minute 4 (MDM4)/tumor suppressor p53/glutathione peroxidase 4 (GPX4) signaling pathway. MethodsSeventy SPF-grade female SD rats were randomly divided into a blank group (n = 10), a sham-operated group (n = 10), and a modeling group (n = 50). The sham-operated group underwent laparotomy, while the modeling group was subjected to the autotransplantation method to establish an endometriosis model. After successful modeling, the animals were randomly assigned to the model group, progesterone group (0.25 mg·kg-1), and modified Shaofu Zhuyutang high-, medium-, and low-dose groups (30, 15, and 7.5 g·kg-1, respectively), with 10 rats per group. After four weeks of drug administration, the rats were euthanized for sample collection. The weight and volume of ectopic endometrial tissues were recorded for each group. Transmission electron microscopy (TEM) was employed to observe ultrastructural changes in endometrial tissues, while Prussian blue staining was used to assess iron ion deposition. Serum levels of interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) were measured by enzyme-linked immunosorbent assay (ELISA). The relative levels of Fe2+, malondialdehyde (MDA), and glutathione (GSH) in endometrial tissues were determined by colorimetric assay. Immunofluorescence (IF) was used to detect the relative fluorescence intensities of GSH and GPX4 in endometrial tissues. The relative expression levels of phosphatidylinositol 3-kinase (PI3K), phosphorylated PI3K (p-PI3K), protein kinase B (Akt), phosphorylated Akt (p-Akt), MDM4, p53, and GPX4 proteins were detected by Western blot. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to assess the mRNA expression of PI3K, Akt, MDM4, p53, and GPX4. ResultsCompared with the blank and sham-operated groups, the model group exhibited reduced ferroptotic damage in ultrastructural observations, decreased ferroptotic aggregates and positive iron ion expression area on Prussian blue staining, elevated serum IL-6, IL-1β, and TNF-α levels, reduced Fe2+ and MDA content, increased GSH content in endometrial tissues, and enhanced GSH and GPX4 fluorescence intensities (P<0.01). The protein and mRNA expression levels of PI3K, p-PI3K, Akt, p-Akt, MDM4, and GPX4 were elevated, while those of p53 were decreased (P<0.01). Compared with the model group, in the progesterone group and the modified Shaofu Zhuyutang high- and medium-dose groups, ferroptotic damage in ultrastructural observations was exacerbated to varying degrees by TEM, and ferroptotic aggregates and positive iron ion expression areas were increased on Prussian blue staining. Serum IL-6, IL-1β, and TNF-α levels decreased, Fe2+ and MDA content increased, and GSH content decreased in endometrial tissues. GSH and GPX4 fluorescence intensities weakened, while the protein and mRNA expression levels of PI3K, p-PI3K, Akt, p-Akt, MDM4, and GPX4 decreased, and those of p53 increased (P<0.05, P<0.01). Conclusionmodified Shaofu Zhuyutang may exert therapeutic effects in endometriosis by inducing ferroptosis in ectopic endometrial tissues, alleviating inflammatory responses, and modulating key proteins in the MDM4/p53/GPX4 signaling pathway.

Objective:
To explore the association of latent profiles of mobile phone dependence and self control with physical exercise among junior high school students, so as to provide references for the prevention of mobile phone dependence and the improvement of self control among junior high school students.
Methods:
From April to May 2024, a stratified random cluster sampling method was used to select a total of 2 311 students from grade 7 to grade 9 in three public junior high schools in Xiangxi Autonomous Prefecture, Hunan Province. Latent profile analysis was conducted to identify the latent profiles of mobile phone dependence and self control among junior high school students. Pearson correlation analysis was used to examine the correlation between mobile phone dependence and self control, and Chi square test was used to analyze the distribution differences of latent profiles of adolescents across different demographic characteristics. Multiple Logistic regression analysis was applied to explore the association between mobile phone dependence, self control, and physical exercise.
Results:
Four latent profiles of mobile phone dependence and self control were identified: low dependence-moderate self control group ( n =885, 38.3%), moderate dependence-low self control group ( n =910, 39.4%), high dependence-no self control group ( n =232, 10.0%), and no dependence-high self control group ( n =284, 12.3%). Significant differences were observed in the distribution of latent profiles across gender, grade and only child status ( χ 2=10.85, 35.72, 13.85, P <0.05). Logistic regression analysis showed that, after controlling for demographic variables, compared with the low dependence-moderate self control group, physical exercise was negatively associated with the moderate dependence-low self control group ( OR =0.79) and the high dependence-no self control group ( OR =0.81), while positively associated with the no dependence-high self control group ( OR =1.58) ( P <0.01).
Conclusions
The influence of physical exercise on junior high school students different potential profile types of mobile phone dependence and self control is different. Schools and families should adopt targeted physical exercise interventions based on the characteristics of different profiles to promote the physical and mental health of junior high school students.

FU Qingzhu Nyuke·Zhongzi is a concentrated manifestation of Fu′s academic thoughts of promoting conception (Zhongzi), which affects the treatment of infertility in later generations. However, the Zhongzi chapter is named after "symptoms" and is not divided into chapters according to "syndromes, "limiting the clinical application of Fu′s thoughts of Zhongzi. The "qi circle in round" theory is the crystallization of HUANG Yuanyu′s academic thinking, advocating for qi transformation, emphasizing middle qi, and considering the four phenomena. This theory highlights the role of middle qi in the rise, fall, and circulation of disease development. The "qi cycle in round" theory, a comprehensive view of Fu′s Zhongzi chapter, reveals that FU Qingzhu emphasizes the transformation of visceral qi in diagnosing and treating infertility, focusing on the spleen, liver, and kidneys. His prescription aims to restore the overall qi mechanism of the body, highlighting the circulation of middle earth and the dredging of meridians, aligning perfectly with the theory of the "qi cycle in round." Therefore, this article argues from the perspective of the "qi cycle in round, "deconstructing the pathogenesis of Fu′s infertility based on the dereliction of spleen earth, stagnation of liver wood, and kidney yin and yang deficiency. It reorganizes Fu′s formula system of Zhongzi by mediating middle earth, soothing liver depression, and regulating kidney function, summarizing the characteristics of Fu′s thoughts of Zhongzi with the aid of qi around the waist and navel, simultaneous treatment of conqenital and acquired essence, and restriction and generation of five phases. Based on the "qi cycle in round" theory, this study explores Fu′s academic thoughts of Zhongzi to strengthen the organic integration of Fu′s academic thoughts of Zhongzi with the theory of "qi cycle in round, "providing new perspectives for the study and inheritance of Fu′s academic thoughts of Zhongzi.

Objective:
To analyze the heterogeneity of mobile phone dependence development trajectory in middle school students and its association with loneliness and selfcontrol ability, so as to provide reference for the prevention of mobile phone dependence in middle school students.
Methods:
A total of 941 grade 1 students from 4 public middle schools in Xiangxi Autonomous Prefecture, Hunan Province were selected for the followup survey by random cluster sampling from October 2023 to April 2024 and October 2024. Mobile Phone Addiction Index (MPAI), University of California, Los Angeles Loneliness Scale-20 (UCLA-20) and Selfcontrol Scales (SCS) were used for questionnaire survey. The heterogeneity of the developmental trajectory of middle school students mobile phone dependence was analyzed by the latent growth curve model (LGMM), and the influencing factors of the developmental trajectory of middle school students mobile phone dependence were explored by multiple Logistic regression analysis.
Results:
The development trajectory of middle school students mobile phone dependence could be divided into four categories: C1 "low risk slow decline group (n=438,44.6%)", C2 "medium risk slow rise group (n=272,29.7%)", C3 "high risk rapid decline group (n=73,8.6%)" and C4 "high risk rapid rise group (n=158,17.1%)". There were significant differences in the distribution of mobile phone dependence development track heterogeneity subgroups among sex, only child, lodging, and leftbehind students (χ2=117.79, 44.88, 37.09, 130.50, P <0.01). The results of the multinomial Logistic regression model analysis showed that, with C1 group as the reference, C2, C3, and C4 were positively correlated with students loneliness [OR(95%CI)=1.04 (1.02-1.06), 1.11(1.08-1.14), 1.12(1.09-1.14)]; C2 and C4 groups were negatively correlated with students selfcontrol [OR(95%CI)=0.97(0.96-0.99), 0.95(0.93-0.97)] (P<0.01).
Conclusions
The development trajectory of mobile phone dependence among middle school students is heterogeneous. Reducing the loneliness of individuals and cultivating good selfcontrol ability are helpful to alleviate mobile phone dependence behavior among middle school students.

Objective:
To explore the influence of social support and school connectedness on the developmental trajectory of self efficacy in adolescents and analyze its subgroup effects, so as to provide a basis for enhancing adolescents self-efficacy.
Methods:
Using a cluster random sampling method, 930 first year middle school students from four schools in Xiangxi Autonomous Prefecture, Hunan Province, were selected for three longitudinal surveys in October 2023 (T1), April 2024 (T2), and October 2024 (T3). The General Self-efficacy Scale (GSES), Social Support Scale (SSS), and School Connectedness Scale (SCS) were administered. Latent growth mixture modeling (LGMM) was used to identify different developmental trajectories of self-efficacy in early adolescence. Multivariate Logistic regression was employed to examine the associations of self-efficacy trajectories with social support and school connectedness in adolescents.
Results:
The developmental trajectory of self-efficacy in adolescents was classified into three categories:category 1 was low efficacy-rapid growth group (53 students, 6.6%), category 2 was moderate efficacy-stable growth group (793 students, 84.1%), and category 3 was high efficacy-rapid decline group (84 students, 9.3%). Using the low efficacy- rapid growth group as the reference, students with higher social support were more likely to belong to the moderate efficacy- stable growth group ( OR=1.06, 95%CI =1.03-1.08) and the high efficacy-rapid decline group ( OR=1.06, 95%CI = 1.03 -1.09), students with higher school connectedness were more likely to belong to the high efficacy-rapid decline group ( OR= 1.10 , 95%CI =1.03-1.18) (all P <0.05). Subgroup analysis revealed significant effects for boarding status (low efficacy-rapid growth group at T1, t =2.10; high efficacy-rapid decline group in social support, t =-2.15) and only child status (moderate efficacy-stable growth group at T2, t =2.05) (all P <0.05).
Conclusions
The developmental trajectory of self-efficacy in adolescents exhibits group heterogeneity, with boarding status and only child status showing subgroup effects. Enhancing social support and school connectedness can help improve self-efficacy in adolescents.

ObjectiveTo explore the mechanism of action of Cuscutae Semen-Salviae Miltiorrhizae Radix et Rhizoma in the treatment of recurrent spontaneous abortion (RSA) through network pharmacology, molecular docking, and cell experiment verification. MethodsThe Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and UniPort databases were used to screen and organize the active ingredients and corresponding targets of Cuscutae Semen-Salviae Miltiorrhizae Radix et Rhizoma. The potential therapeutic targets of RSA were screened in Online Mendelian Inheritance in Man (OMIM), GeneCards database, DrugBank database, DisGeNET database, and Therapeutic Target Database (TTD). The potential core targets of Cuscutae Semen-Salviae miltiorrhizae Radix et Rhizoma for treating RSA were further screened by constructing a protein-protein interaction (PPI) network and topological analysis. Meanwhile, the Database for Annotation, Visualization and Integrated Discovery (DAVID) was chosen to perform enrichment analysis on intersection targets. On this basis, AutoDock software was used for molecular docking, and the data were imported into PyMOL software for visualization and composition. Finally, the cell counting kit-8 (CCK-8) experiment, Transwell cell invasion assay, and Western blot were used to detect the effects of serum containing Cuscutae Semen-Salviae miltiorrhizae Radix et Rhizoma on HTR-8/SVneo cells and observe the effects on the interleukin (IL)-6/signal transducer and activator of transcription 3(STAT3) signaling pathway and related proteins. ResultsThrough network pharmacology analysis, a total of 69 active ingredients, 73 potential therapeutic targets, and 17 core targets, including IL-6, IL-10, and STAT3, were collected. The 73 common targets were enriched in 614 Gene Ontology (GO) entries and 57 Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathways. The molecular docking results indicated that IL-6 and STAT3 had good binding ability with the main active ingredients, including matrine, cryptotanshinone, and tanshinone ⅡA. The cell experiment results showed that, compared with those of the control group, after 24 hours of treatment with the drug-containing serum, the survival and invasion rates of HTR-8/SVneo cells were significantly increased (P<0.05), and the expression of IL-6/STAT3 signaling pathway and related proteins IL-10 and c-Myc was significantly elevated (P<0.05). Moreover, the trend of action in the drug-containing serum group was consistent with that of pathway agonists. ConclusionCuscutae Semen-Salviae miltiorrhizae Radix et Rhizoma may enhance the survival rate and invasive activity of HTR-8/SVneo cells to further prevent and treat RSA by activating the IL-6/STAT3 signaling pathway and upregulating the expression of downstream factors IL-10 and c-Myc in the pathway.

Objective To summarize the experience and practical value of living donor kidney harvesting in Bama miniature pigs with six gene modified. Methods The left kidney of Bama miniature pigs with six gene modified was obtained by living donor kidney harvesting technique. First, the ureter was occluded, and then the inferior vena cava and abdominal aorta were freed. During the harvesting process, the ureter, renal vein and renal artery were exposed and freed in sequence. The vascular forceps were used at the abdominal aorta and inferior vena cava, and the renal artery and vein were immediately perfused with 4℃ renal preservation solution, and stored in ice normal saline for subsequent transplantation. Simultaneously, the donor abdominal aorta and inferior vena cava gap were sutured. The operation time, blood loss, warm and cold ischemia time, postoperative complications and the survival of donors and recipients were recorded. Results The left kidney of the genetically modified pig was successfully harvested. Intraoperative bleeding was 5 mL, warm ischemia time was 45 s, and cold ischemia time was 2.5 h. Neither donor nor recipient pig received blood transfusion, and urinary function of the kidney transplanted into the recipient was recovered. The donor survived for more than 8 months after the left kidney was resected. Conclusions Living donor kidney harvesting is safe and reliable in genetically modified pigs. Branch blood vessels could be processed during kidney harvesting, which shortens the process of kidney repair and the time of cold ischemia. Living donor kidney harvesting contributes to subsequent survival of donors and other scientific researches.
