ObjectiveTo investigate whether Shenmai injection （SMI） improves cisplatin resistance in non-small cell lung cancer （NSCLC） by modulating lipid metabolism and inducing ferroptosis. MethodsHuman lung adenocarcinoma cisplatin-resistant A549/DDP cells were divided into the following groups： Blank group， cisplatin group （23.3 μmol·L^-1 cisplatin）， SMI group （20 g·L^-1 SMI）， cisplatin combined with SMI group （23.3 μmol·L^-1 cisplatin + 20 g·L^-1 SMI）， cisplatin combined with ferroptosis inhibitor/inducer Ferrostatin-1/Erastin group （23.3 μmol·L^-1 cisplatin + 10 μmol·L^-1 Ferrostatin-1/5 μmol·L^-1 Erastin）， and cisplatin combined with SMI and Ferrostatin-1/Erastin group （23.3 μmol·L^-1 cisplatin + 20 g·L^-1 SMI + 10 μmol·L^-1 Ferrostatin-1/5 μmol·L^-1 Erastin）. Network pharmacology， transcriptomics and metabolomics， Cell Counting Kit-8 （CCK-8） assay， transmission electron microscopy （TEM）， colorimetric assays， and Western blot analysis were employed to evaluate the effects of these treatments on A549/DDP cell viability， lipid droplet formation， lipid metabolite levels， mitochondrial function， lipid peroxidation， glutathione （GSH） content， total and ferrous iron content， and effects on ferroptiosis and autophagy related protein expression levels. ResultsSMI improved cisplatin resistance in NSCLC mainly by targeting lipid metabolism-related pathways in A549/DDP cells， affecting tumor cell lipid metabolism via autophagy， ferroptosis， and glycerophospholipid metabolism pathways. Compared with the cisplatin group， the cisplatin combined with SMI group showed significantly decreased cell viability （P<0.01）， increased lipid droplet accumulation （P<0.01）， and reduced mitochondrial maximal respiration， basal respiration， mitochondrial membrane potential， GSH content， total iron， and ferrous iron （all P<0.01）. Mitochondrial reactive oxygen species （ROS） was significantly elevated（P<0.01）， and lipid peroxidation levels were significantly increased. Protein expression analysis showed significant downregulation of solute carrier family 7 member 11 （SLC7A11） and p62 （P<0.05，P<0.01） and upregulation of ferritin heavy chain （FTH） and microtubule-associated protein 1 light chain 3Ⅱ （LC3Ⅱ） （P<0.05，P<0.01）. Compared with the cisplatin combined with SMI group， addition of Ferrostatin-1 significantly increased cell viability （P<0.05）， decreased mitochondrial ROS levels （P<0.05）， alleviated mitochondrial shrinkage， and reduced lipid peroxidation. Conversely， addition of Erastin further decreased cell viability （P<0.01）. ConclusionSMI improves cisplatin resistance in NSCLC by inducing oxidative stress， which may trigger ferroptosis through upregulation of lipophagy.

ObjectiveTo evaluate the effect of sex on phenotypic stability in mouse models of chemotherapy-induced alopecia (CIA) induced by cyclophosphamide (CYP) or paclitaxel (PTX), and to explore potential mechanisms underlying phenotypic heterogeneity in female mice. MethodsTwenty-eight wild-type specific pathogen-free (SPF) C57BL/6J mice (half male and half female) aged 6-8 weeks were selected for synchronous back hair removal. On the 9th day after hair removal (T0), the mice were randomly divided into a wild-type female CYP group, a wild-type male CYP group, a female negative control group and a male negative control group. Mice in the CYP groups were intraperitoneally injected with a single dose of 120 mg/kg CYP, and mice in the negative control groups were intraperitoneally injected with the same volume of normal saline. Subsequently, the phenotypic changes of the CIA model induced by CYP were continuously observed and photographed. Eleven 6-week-old SPF female C57BL/6J mice underwent bilateral ovariectomy (OVX group). Following successful surgery, these mice and five XY (Sry⁻) mice bred from Four Core Genotypes breeding stock were used to establish the chemotherapy-induced alopecia (CIA) model using the same protocol. Serum was collected from mice in the OVX group, wild-type female CYP group, and wild-type male CYP group on T7 after CYP administration for steroid hormone analysis by mass spectrometry to evaluate the effects of gonadal estrogen and sex chromosome background changes on the stability of the CYP-induced female alopecic phenotype. Finally, twenty SPF C57BL/6J mice aged 6-8 weeks (half male and half female) were randomly divided into a PTX low-dose group and a PTX high-dose group. On the 9th day after simultaneous hair removal, PTX was injected intraperitoneally at a single dose of 80 mg/kg or 120 mg/kg, respectively. Mice from the PTX low-dose group and the PTX high-dose group were continuously observed and photographed to compare the intra-group consistency of the phenotypes of female and male mice. Six SPF C57BL/6J mice (half male and half female) aged 6-8 weeks were used to repeat the construction method of the PTX low-dose group, and the hair follicle histological examination was performed at T0, T4, T7, T14 and T21, respectively, to observe the damage caused by PTX to hair follicle regeneration. ResultsThe phenotypes of CYP-induced male CIA mice are stable and reproducible. There are obvious individual differences in the alopecia phenotype in the CYP-induced female CIA model mice, which may be mainly caused by the differences in the relevant estrogens in the estrous cycle. The difference between OVX+CYP group and XY (Sry⁻) +CYP group disappeared, suggesting that ovarian-derived hormones and XY (Sry⁻) sex chromosome background may be involved in the formation of phenotypic heterogeneity of CYP-induced alopecia in female mice. The mice in the high-dose PTX group and the low-dose PTX group showed a relatively consistent alopecia and regrowth process, and there was no significant sex difference. ConclusionCYP-induced CIA is strongly influenced by sex, and ovariectomy or alteration of the sex chromosome background can improve the consistency of CYP-induced alopecic phenotypes in female mice. PTX-induced CIA shows good phenotypic consistency in both female and male mice, indicating broad applicability across sexes. Taken together, the choice of animal sex in CIA model construction, mechanistic studies, and evaluation of anti-alopecia interventions should take into account the type of chemotherapeutic agent, the study objective, and the required degree of phenotypic stability. Sex should therefore be considered an important variable in model standardization and interpretation of experimental findings.

OBJECTIVE To explore the improvement effect and mechanism of salidroside on radiation-induced parotid gland injury in rats. METHODS Rats were randomly assigned into normal group， radiation group， salidroside low-dose （salidroside-L， 50 mg/kg） group， salidroside high-dose （salidroside-H， 100 mg/kg） group， and salidroside-H+inhibitor （100 mg/kg salidroside+0.1 µmol/kg H-89） group， with 10 rats in each group. Except for the normal group， rats in the other groups were subjected to radiation exposure to establish a model of radiation-induced parotid gland injury. Rats in each group were intraperitoneally injected with the corresponding drug or normal saline， once a day， for 40 consecutive days. After the last administration， the levels of reactive oxygen species （ROS）， cyclic adenosine monophosphate （cAMP）， superoxide dismutase （SOD）， and amylase in serum were detected； the pathological changes of parotid gland tissue were observed； the apoptosis rate of parotid gland tissue cells， the expression levels of B-cell lymphoma-2 （Bcl-2） and its associated X protein （Bax）， mRNA expression levels of interleukin-6 （IL- 6） and tumor necrosis factor-α （TNF-α）， the protein expression levels of type Ⅲ collagen （Col Ⅲ）， vasoactive intestinal peptide （VIP）， and the phosphorylation level of protein kinase A （PKA） in parotid gland tissue were determined. RESULTS Compared with normal group， the levels of ROS， amylase， apoptosis rate， Bax expression level， mRNA expression levels of IL-6 and TNF- α， and protein expression level of Col Ⅲ in the radiation group were significantly increased， while the levels of cAMP， SOD， Bcl-2 expression level， VIP protein expression level and PKA phosphorylation level were significantly decreased （P＜0.05）. Compared with radiation group， the above indicators in the salidroside-L group and salidroside-H group were significantly improved （P＜0.05）， and the improvement in the salidroside-H group was more significant （P＜0.05）； inhibitor H-89 significantly reversed the changes in the above indicators of the salidroside-H group （P＜0.05）. CONCLUSIONS Salidroside can effectively alleviate radiation-induced parotid gland injury in rats， and its mechanism may be related to the activation of the VIP-cAMP pathway.

Objective:To discuss the diagnostic value of levels of growth stimulation expressed gene 2 protein(ST2),carbohydrate antigen 125(CA125),and human epididymis protein 4(HE4)in serum of the ovarian cancer patients,and to clarify their relationships with clinicopathological parameters of the ovarian cancer patients.Methods:A total of 136 patients with ovarian benign lesions or primary ovarian malignancies in our hospital confirmed by postoperative histopathology were randomly selected,including 53 cases in ovarian benign ovarian disease group and 83 cases in ovarian cancer group.Additionally,55 healthy female volunteers during the same period were enrolled as healthy control group.The fasting venous blood from all the subjects was collected on the first day of admission,and serum was retained;cyclic enhanced fluorescence immunoassay was used to detect ST2 levels of the subjects in various groups;chemiluminescence method was used to detect serum CA125 and HE4 levels of the subjects in various groups;receiver operating characteristic(ROC)curve was used to assess the diagnostic performance of each indicator;the Cut-off value and area under the ROC curve(AUC)were calculated,with AUC representing the diagnostic performance;Kendall's method was used to analyze the correlations between serum ST2 levels and TNM stage,maximum tumor diameter,distant metastasis,lymphnode metastasis,peritoneal metastasis,carcinoembryonic antigen(CEA),CA125,carbohydrate antigen 199(CA199),HE4,P53,and Kiel-67(Ki67)in the ovarian cancer patients.Results:Compared with healthy control group,the serum CA125 level of the patients in ovarian benign ovarian disease group was significantly increased(P<0.05).Compared with healthy control group and ovarian benign group,the serum levels of ST2,CA125,and HE4 of the patients in ovarian cancer group were significantly increased(P<0.05).The AUC values were 0.719(95%CI:0.616-0.822)for ST2,0.868(95%CI:0.794-0.942)for CA125,and 0.867(95%CI:0.793-0.942)for HE4.The combined detection of ST2+CA125+HE4 yielded an AUC of 0.894(95%CI:0.832-0.955).Significant differences were observed in serum ST2,CA125,and HE4 levels among ovarian cancer patients with different TNM stages,lymph node metastasis,distant metastasis,and peritoneal metastasis(P<0.05),while there were no significant differences in the patients with different ages or maximum tumor diameters(P>0.05).The ST2 level in serm of the ovarian cancer patients was positively correlated with TNM stage,distant metastasis,lymph node metastasis,peritoneal metastasis,CA125 level,HE4 level,and Ki67 level(P<0.05),but was not correlated with maximum tumor diameter,CEA,CA199 level,or P53 level(P>0.05).Conclusion:ST2,CA125,and HE4 are highly expressed in the serum of the ovarian cancer patients.Combined detection of serum ST2,CA125,and HE4 exhibits good sensitivity and specificity for ovarian cancer screening and improves diagnostic efficacy.ST2 is associated with advanced TNM stage and metastasis in ovarian cancer and may participate in the occurrence and progression of ovarian cancer.

BackgroundAttention deficit hyperactivity disorder （ADHD） is a neurodevelopmental disorder characterized by age-inappropriate inattention， excessive activities incongruous with setting， and emotional impulsivity. Subthreshold ADHD （sADHD） is clinically defined as the presence of ADHD symptoms that do not meet the full diagnostic criteria for ADHD. Children with sADHD exhibit deficits in executive function， demonstrate more conduct， learning， and anxiety-related problems compared to typically developing children， and show even poorer working memory performance than children diagnosed with ADHD. Currently， there is limited epidemiological research on sADHD in China， with few studies simultaneously investigating the prevalence of both ADHD and sADHD in children. ObjectiveTo investigate the prevalence of ADHD and sADHD among children aged 6–13 years in Chongqing， analyzing their distribution characteristics within this population， with the aim of providing references for developing preventive measures against both ADHD and sADHD. MethodsFrom October to November 2023， a total of 3 398 students in grades 1–6 from six primary schools in Jiangbei District， Chongqing were selected using a stratified cluster random sampling method. The occurrence of ADHD and sADHD was evaluated by using the short version （18-item version） of the Swanson， Nolan， and Pelham IV rating scales （SNAP-IV） and the Chinese vision of Schedule for Affective Disorder and Schizophrenia for School-aged Children-Present and Lifetime Version （K-SADS-PL）. ResultsThe ADHD detection rate among children in Chongqing was 1.90% （95% CI： 0.014–0.024）. Boys showed a significantly higher ADHD detection rate than girls （χ²=7.733， P=0.005）. No statistically significant differences were found in ADHD detection rates across different grades or age groups （χ²=7.347， 12.362， P>0.05）. The sADHD detection rate was 6.32% （95% CI： 0.054–0.072）. Similarly， boys exhibited significantly higher sADHD detection rates than girls （χ²=21.005， P<0.01）. Significant differences emerged across different grades （χ²=20.559， P=0.001）， while no statistically significant difference was observed in age groups （χ²=12.070， P=0.060）. ConclusionThe ADHD detection rates were comparable across all grade levels and age groups from 6–13 years old. Second-grade children demonstrated notably higher sADHD rates compared to other grades， while boys demonstrated higher prevalence rates than girls for both ADHD and sADHD. ［Funded by Science and Health Joint Medical Research Project in Jiangbei District， Chongqing City in the Second Half of 2023 （number， 2023JBKWLH022）］

OBJECTIVE: To investigate the gene detection results of 2 patients with familial hypercholesterolemia (FH) caused by complex heterozygous variation, and to clarify the relationship between clinical manifestations and gene variation. METHODS: Two patients (patient 1 and 2) with FH who visited Beijing Anzhen Hospital Affiliated to Capital Medical University in 2018 were selected as research subjects. A retrospective study method was used to collect clinical and family history data of the two patients. And 2 mL of peripheral venous blood from each of the two patients was collected, and genomic DNA extraction was performed on the blood samples. Sanger sequencing was used to validate the variant sites of the two patients detected by whole-exome sequencing (WES). Pathogenicity of variants was classified based on the American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Classification of Genetic Variants (hereinafter referred to as the "ACMG Guidelines"), and the impact of variant was analyzed using multiple bioinformatics tools including SIFT, PolyPhen-2, and SWISS-MODEL. This study has been approved by Beijing Anzhen Hospital Affiliated to Capital Medical University (Ethics No. 2024215X). RESULTS: Patient 1 initially presented with early-onset coronary heart disease, with initial lipid levels of serum total cholesterol (TC) 9.86 mmol/L (normal reference value: 3.10~5.20 mmol/L) and serum low-density lipoprotein cholesterol (LDL-C) 8.37 mmol/L (normal reference value: 1.27~3.12 mmol/L) on admission. Patient 1 initially underwent treatment with rosuvastatin combined with ezetimibe for one month, but the lipid-lowering effect was not significant. The lipid-lowering therapy was then adjusted to atorvastatin combined with ezetimibe and probucol. After one year of treatment, the patient developed paroxysmal chest pain symptoms. A follow-up lipid profile showed a serum TC level of 4.50 mmol/L and a LDL-C level of 3.55 mmol/L. The lipid-lowering regimen was continued, and the serum LDL-C levels were maintained between 2.65 and 3.66 mmol/L. Patient 2 was found to have an abnormally high blood lipid level and carotid artery hardening during physical examination, with an initial blood lipid level of serum TC 11.82 mmol/L and serum LDL-C 9.63 mmol/L. After receiving rosuvastatain therapy, the lipid-lowering effect was significant. WES revealed that patient 1 carried the heterozygous variants c.1871_1873del(p.Ile624del) and c.1747C>T (p.His583Tyr) in the LDLR gene (NM_000527.4), while patient 2 carried the heterozygous variants c.1747C>T (p.His583Tyr) in the LDLR gene and c.6936_6937inv (p.Ile2313Val) in the APOB gene (NM_000384). According to the ACMG Guidelines, the LDLR gene c.1747C>T (p.His583Tyr) was classified as a pathogenic variant (PS3+PM1+PM2_supporting+PM5+PP2+PP3), and c.1871_1873del (p.Ile624del) was classified as a pathogenic variant (PS3+PS4+PM2_supporting+PM1+PM4); the APOB gene c.6936_6937inv (p.Ile2313Val) was classified as a variant of uncertain clinical significance (PM2_supporting BP4). CONCLUSION Patients 1 and 2 in this study were patients with complex heterozygous variant FH, and their genotypic differences may be related to the differences in clinical serum LDL-C levels and the efficacy of hypolipidemic agents.

Objective:To analyze the clinical characteristics of children with head and neck rhabdomyosarcoma (RMS) and to summarize the mid-long term efficacy of Beijing Children′s Hospital Rhabdomyosarcoma 2006 (BCH-RMS-2006) regimen and China Children′s Cancer Group Rhabdomyosarcoma 2016 (CCCG-RMS-2016) regimen.Methods:A retrospective cohort study. Clinical data of 137 children with newly diagnosed head and neck RMS at Beijing Children′s Hospital, Capital Medical University from March 2013 to December 2021 were collected. Clinical characteristic of patients at disease onset and the therapeutic effects of patients treated with the BCH-RMS-2006 and CCCG-RMS-2016 regimens were compared. The treatments and outcomes of patients with recurrence were also summarized. Survival analysis was performed by Kaplan-Meier method, and Log-Rank test was used for comparison of survival rates between groups.Results:Among 137 patients, there were 80 males (58.4%) and 57 females (41.6%), the age of disease onset was 59 (34, 97) months. The primary site in the orbital, non-orbital non-parameningeal, and parameningeal area were 10 (7.3%), 47 (34.3%), and 80 (58.4%), respectively. Of all patients, 32 cases (23.4%) were treated with the BCH-RMS-2006 regimen and 105 (76.6%) cases were treated with the CCCG-RMS-2016 regimen. The follow-up time for the whole patients was 46 (20, 72) months, and the 5-year progression free survival (PFS) and overall survival (OS) rates for the whole children were (60.4±4.4)% and (69.3±4.0)%, respectively. The 5-year OS rate was higher in the CCCG-RMS-2016 group than in BCH-RMS-2006 group ((73.0±4.5)% vs. (56.6±4.4)%, χ2=4.57, P=0.029). For the parameningeal group, the 5-year OS rate was higher in the CCCG-RMS-2016 group (61 cases) than in BCH-RMS-2006 group (19 cases) ((57.3±7.6)% vs. (32.7±11.8)%, χ2=4.64, P=0.031). For the group with meningeal invasion risk factors, the 5-year OS rate was higher in the CCCG-RMS-2016 group (54 cases) than in BCH-RMS-2006 group (15 cases) ((57.7±7.7)% vs. (30.0±12.3)%, χ2=4.76, P=0.029). Among the 10 cases of orbital RMS, there was no recurrence. In the non-orbital non-parameningeal RMS group (47 cases), there were 13 (27.6%) recurrences, after re-treatment, 7 cases survived. In the parameningeal RMS group (80 cases), there were 40 (50.0%) recurrences, with only 7 cases surviving after re-treatment. Conclusions:The overall prognosis for patients with orbital and non-orbital non-parameningeal RMS is good. However, children with parameningeal RMS have a high recurrence rate, and the effectiveness of re-treatment after recurrence is poor. Compared with the BCH-RMS-2006 regimen, the CCCG-RMS-2016 regimen can improve the treatment efficacy of RMS in the meningeal region.

Background: Psoralea corylifolia L. (Buguzhi, BGZ), known for its efficacy in supporting pregnancy and preventing miscarriage, has been used in China for over 1000 years. Recently, BGZ has been identified as a potential cause of drug-induced liver injury. However, its safety during pregnancy remains unclear, which significantly hinders its routine clinical application. Objective: To investigate the effects of BGZ administration during pregnancy on the liver of mouse mothers and their weaned 21-day-old offspring. Methods: Mice were orally administered BGZ at doses of 2.5 and 10 g/kg during pregnancy, with BGZ withdrawal during the lactation period. Liver histopathology (hematoxylin-eosin staining), biochemical analysis, and evaluation of liver bile acid metabolism were performed after the lactation period. Results: BGZ administration at doses of 2.5 and 10 g/kg during pregnancy, followed by withdrawal during the lactation period, caused mild liver damage in both mothers and their 21-day-old offspring. Serum total bile acid (TBA) levels were elevated compared with those in the control group. Additionally, changes were observed in the levels and proportions of various bile acids (BAs) in the liver, suggesting mild effects on BA metabolism. Conclusion: BGZ administration during pregnancy caused mild liver damage and increased serum TBA levels in both mouse mothers and their 21-day-old offspring. This phenomenon may be associated with imbalanced BA metabolism in the liver. Based on the present study and the limited toxicological research on BGZ, pregnant women should avoid prolonged use of BGZ. If BGZ is administered during pregnancy, serum TBA levels should be monitored, and if elevated, BGZ should be discontinued.

Background: Aristolochic acid II (AAII), a major nephrotoxic and carcinogenic component of aristolochic acids (AAs), has been less studied compared with its well-characterized analog, aristolochic acid I (AAI). Although AAs are known to induce carcinogenesis via DNA adduct formation, the toxicity mechanisms, environmental prevalence, and long-term health impacts of AAII remain poorly understood. Objective: This study aimed to systematically evaluate AAII’s acute and chronic toxicity, carcinogenic mechanisms, and environmental exposure patterns using integrated murine models and phytochemical analyses to clarify its toxicological profile and associated health risks. Methods: C57BL/6J mice were used in the following experiments: (1) determination of AAII content in 3 commonly used Aristolochia medicinal materials via liquid chromatography-mass spectrometry/mass spectrometry; (2) acute toxicity testing with single doses of 10, 20, or 40 mg/kg; and (3) chronic exposure with 1 or 10 mg/kg administered every other day for 24 weeks, followed by 21 to 40 weeks of postexposure monitoring. Histopathological examination, whole-exome sequencing, biochemical assays, and micronucleus tests were performed to assess multi-organ damage, tumorigenesis, genomic mutation signatures, and direct clastogenicity. Phytochemical analyses were used to evaluate environmental distribution. Results: (1) A single 40 mg/kg dose of AAII induced dose-dependent renal tubular degeneration without hepatotoxicity; (2) the 10 mg/kg group showed significant mortality (20%), tumor incidence (33.3%, primarily forestomach and bladder transitional cell carcinomas), persistent renal interstitial fibrosis, and subclinical hepatic injury. Chronic exposure to 1 mg/kg still induced 13.3% mortality and 15.5% tumor incidence over a 64-week period; (3) whole-exome sequencing revealed a predominance of C>T mutations and pathway enrichment in chemical carcinogenesis and cytochrome P450-mediated metabolism, indicating reactive metabolite-driven mechanisms distinct from classical AA-DNA adducts; and (4) no histopathological changes were observed in nontarget organs (brain, heart, and testes), and micronucleus assays confirmed the absence of direct clastogenicity. Conclusion: This study highlights the delayed carcinogenic risks of low-dose chronic AAII exposure and emphasizes the need to update regulatory frameworks to ensure the safe use of aristolochiaceae-containing herbal products.

Objective To investigate the therapeutic effects of combined magnetic and electrical stimulation with an"intelligent exercise prescription"and novel matrix radiofrequency therapy in patients with pelvic organ prolapse(POP).Methods A total of 158 patients with POP who received treatment at the Gynecological Pelvic Floor Rehabilitation Center of the Eighth Affiliated Hospital of Southern Medical University between October 2022 and July 2025 were retrospectively enrolled and divided into an observation group(n=64)and a control group(n=94)based on their treatment plans.The control group underwent magnetic and electrical stimulation combined with an"intelligent exercise prescription"regimen.Specifically,patients received 10 sessions of electrical stimulation,5 sessions of magnetic stimulation,and performed 15～20 minutes of daily home exercise training guided by the"intelligent exercise prescription."The observation group received,in addition to the aforementioned treatments,four sessions of novel matrix radiofrequency therapy.Changes in the muscle strength grades of type Ⅰ and type Ⅱ pelvic floor muscles,Glazer surface electromyography(EMG)values,and POP-Q staging were compared between the two groups before and after treatment.Results After treatment,both groups demonstrated significant improvements in type Ⅰ and type Ⅱ muscle fiber strength compared to baseline(all P<0.05),with the observation group showing greater improvement in type Ⅰ muscle fiber strength than the control group(P<0.05).The muscle potential values of the observation group during rapid contraction,tense contraction,and endurance contraction stages were markedly increased compared to pre-treatment levels.Moreover,the muscle potential values during the pre-resting stage were significantly reduced after treatment(P<0.05).In the observation group,POP-Q grades of the anterior vaginal wall,uterus,and posterior vaginal wall were all significantly lower post-treatment than pre-treatment(all P<0.05).However,no statistically significant differences were observed between the observation group and the control group in these parameters(P>0.05).Both groups exhibited relatively high compliance rates(both≥75.0%),with no significant difference between them(P>0.05).The treatment cost for the observation group was significantly higher than that for the control group(P<0.05).Conclusions The combination of magneto-electrical stimulation,an"intelligent exercise prescription,"and novel matrix radiofrequency therapy can significantly improve pelvic floor muscle strength and muscle potential values in the short term,compared to pre-treatment levels.This integrated approach also effectively alleviates the prolapse of the anterior vaginal wall,uterus,and posterior vaginal wall.Furthermore,the combination of magnetic and electrical stimulation,"intelligent exercise prescription,"and matrix radiofrequency therapy demonstrates superior efficacy in enhancing type Ⅰ pelvic floor muscle fiber strength when compared to the combination of magnetic and electrical stimulation with"intelligent exercise prescription"alone.However,this treatment protocol entails a relatively high economic burden,and its clinical application should be carefully evaluated in consideration of patients'functional needs and financial conditions.
