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.

Ribosome is an intracellular ribonucleoprotein particle that serves as the site of protein biosynthesis. Ribosomal dysfunction caused by mutations in genes encoding ribosomal proteins (RPs) and ribosome biogenesis factors (RBFs) can lead to a spectrum of diseases, collectively known as ribosomopathy. Phase separation is a thermodynamic process that produces multiple phases from a homogeneous mixture. The formation of membraneless organelles and intracellular structures, including ribosomes and nucleoli, cannot occur without the involvement of phase separation. Here, ribosome structure, biogenesis, and their relationship with ribosomopathy are systematically reviewed. The tissue specificity of ribosomopathy and the role of phase separation in ribosomopathy are particularly discussed, which may offer some clues for understanding the mechanisms of ribosomopathy. Then, some new ideas for the prevention, diagnosis, and treatment of ribosomopathy are provided.

Objective:To explore the effects of quercetin on autophagy and proliferation in HBV-positive liver cancer HCCLM3 cells based on STING signaling and its underlying mechanism.Methods:HCCLM3 cells were treated with quercetin (50 μmol/L or 100 μmol/L), designated as the 50 μmol/L group and 100 μmol/L group, respectively. The inhibitory effect of quercetin on HCCLM3 cells was detected using the CCK-8 method. A scratch assay was conducted to assess the impact of quercetin on the migration ability of HCCLM3 cells. A CCK8 and ROS kit was used to detect the effect of quercetin on the levels of reactive oxygen species in HCCLM3 cells. Western blotting was employed to measure the effect of quercetin on the expression of STING signaling and autophagy-related proteins in HCCLM3 cells. RNA interference technology was used to assess the effects of STING signaling inhibition on the expression of autophagy-related proteins and reactive oxygen species levels in HCCLM3 cells. The combined effects of STING activators and quercetin on HCCLM3 cell proliferation and autophagy were evaluated. The t-test was used to detect data differences between two groups, while ANOVA was employed for comparisons among multiple groups, followed by the SNK- q test for further pairwise comparisons. Results:Compared with the control group, quercetin (50 μmol/L and 100 μmol/L groups) significantly inhibited HCCLM3 cell survival activity in a dose-dependent manner (control group: 100%; 50 μmol/L group: 75.25%; 100 μmol/L group: 50.36%, P<0.01 ). Quercetin inhibited HCCLM3 cell migration in a dose-dependent manner (>2 h, control group: 187.16 μm; 50 μmol/L group: 145.22 μm; 100 μmol/L group: 88.21 μm, P<0.01), which significantly increased intracellular reactive oxygen species (ROS) levels in HCCLM3 cells (control group: 1.00; 50 μmol/L group: 1.565; 100 μmol/L group: 2.175, P<0.01). The phosphorylation level of STING was significantly increased ( P<0.01), and the expression of autophagy-related protein microtubule-related protein 1A/1B light chain 3 (LC3) protein was significantly promoted ( P<0.01). Compared with the quercetin group, the cell viability of the small interfering-STING+quercetin group was increased (quercetin group: 56.3%; small interfering-STING+quercetin group: 85.7%, P<0.05), while the expression of autophagy-related protein LC3 was decreased. Compared with the quercetin group, the cell viability of the quercetin+STING activator group was further decreased (quercetin group: 56.7%; quercetin+STING activator group: 35.4%, P<0.01), and the expression levels of STING and autophagy protein LC3 were significantly increased ( P<0.05). Conclusions:STING signaling-regulated cell autophagy mediates the inhibitory effect of quercetin on the proliferation of HCCLM3 cells, and this effect is enhanced after administration of the STING agonist.

Objective:To explore the correlation between serum levels of interleukin-9 (IL-9), platelet activating factor (PAF), total immunoglobulin E (IgE), interferon γ (IFN-γ), and interleukin-4 (IL-4) in patients with chronic spontaneous urticaria (CSU).Methods:Sixty CSU active phase patients admitted to the First Affiliated Hospital of Hebei North University from March 2018 to March 2019 were selected and included in the CSU active phase group. Based on the 7-day Urticaria Activity Score (UAS7), they were divided into three groups: 15 mild group, 25 moderate group, and 20 severe group; And 19 patients who entered the quiescent phase of the disease after 28 days of standardized antihistamine treatment were included in the CSU quiescent phase group. Another 30 healthy subjects who participated in the physical examination at the same time at our hospital′s physical examination center were selected to be included in the healthy control group. 5 ml of fasting elbow vein blood was collected from CSU active and stationary patients, as well as healthy subjects. The serum levels of IL-9, PAF, total IgE, IFN-γ, and IL-4 were detected using enzyme-linked immunosorbent assay. Pearson correlation test was used to analyze the correlation between serum IL-9, PAF levels and total IgE, IFN-γ, and IL-4 levels in CSU active patients.Results:The serum levels of IL-9, PAF, total IgE, and IL-4 in the CSU active phase group were higher than those in the CSU stationary phase group and healthy control group (all P<0.05), and the serum IFN-γ levels were lower than those in the CSU stationary phase group and healthy control group (all P<0.05). There was no statistically significant difference in the levels of the above indicators between the healthy control group and the CSU stationary group (all P>0.05). The serum levels of IL-9, PAF, total IgE, and IL-4 in the severe group were significantly higher than those in the mild and moderate groups (all P<0.05), and the serum IFN-γ levels were significantly lower than those in the mild and moderate groups (all P<0.05); The serum levels of IL-9, PAF, total IgE, and IL-4 in the moderate group were significantly higher than those in the mild group (all P<0.05), and the serum IFN-γ levels were significantly lower than those in the mild group ( P<0.05). Pearson correlation analysis showed that serum IL-9 and PAF levels were positively correlated with serum total IgE and IL-4 levels in CSU active phase patients (IL-9: r=0.726, 0.870, PAF: r=0.788, 0.795, all P<0.01), and negatively correlated with serum IFN-γ levels (IL-9: r=-0.831, PAF: r=-0.816, all P<0.01). Conclusions:The serum levels of IL-9 and PAF in patients with active CSU are elevated and correlated with total IgE, IFN-γ, and IL-4 levels, suggesting that IL-9 and PAF may be related to the occurrence and development of CSU.

Objective To investigate the role of RNA-binding motif protein X-linked(RBMX)in regulating the proliferation,migration,invasion and glycolysis in human bladder cancer cells.Methods A lentivirus vectors system and RNA interference technique were used to construct bladder cancer 1376 and UC-3 cell models with RBMX overexpression and knockdown,respectively,and successful cell modeling was verified using RT-qPCR and Western blotting.Proliferation and colony forming ability of the cells were evaluated using EdU assay and colony-forming assay,and cell migration and invasion abilities were determined using Transwell experiment.The expressions of glycolysis-related proteins M1 pyruvate kinase(PKM1)and M2 pyruvate kinase(PKM2)were detected using Western blotting.The effects of RBMX overexpression and knockdown on glycolysis in the bladder cancer cells were assessed using glucose and lactic acid detection kits.Results RT-qPCR and Western blotting confirmed successful construction of 1376 and UC-3 cell models with RBMX overexpression and knockdown.RBMX overexpression significantly inhibited the proliferation,clone formation,migration and invasion of bladder cancer cells,while RBMX knockdown produced the opposite effects.Western blotting results showed that RBMX overexpression increased the expression of PKM1 and decreased the expression of PKM2,while RBMX knockdown produced the opposite effects.Glucose consumption and lactate production levels were significantly lowered in the cells with RBMX overexpression(P<0.05)but increased significantly following RBMX knockdown(P<0.05).Conclusion RBMX overexpression inhibits bladder cancer progression and lowers glycolysis level in bladder cancer cells by downregulating PKM2 expression,suggesting the potential of RBMX as a molecular target for diagnosis and treatment of bladder cancer.

Objective To explore the application of the integrated graded diagnosis,treatment and ambulance model based on circulation respiration abdomen motor speech (CRAMS) score in patients with multiple traumas. Methods From March 2023 to March 2024,160 patients with multiple traumas admitted to the department of emergency of Shanghai Sixth People's Hospital were selected as the research subjects. Based on a random number table,the patients were divided into an observation group and a control group,with 80 patients in each group. And the control group received routine emergency treatment,while the observation group was assessed by the intervention team using the CRAMS scoring scale to evaluate the condition,and then implemented an integrated graded diagnosis and treatment model based on the assessment results. The specific measures were as follows:establish an intervention team composed of 1 attending doctor from the emergency resuscitation room,1 head nurse specializing in trauma care,and 3 trauma specialty nurses. The attending doctor was responsible for diagnosing and treating the patient's condition;the head nurse specializes in assessing the patient using the CRAMS scoring scale;the trauma specialty nurses were tasked with implementing interventions for the patient. The CRAMS score,injuy seveity scoe (ISS),triage time,waiting time for treatment,treatment time,complication rate,and patient satisfaction rate were compared between the two groups before and after the intervention. Results There were no significant differences in CRAMS scores and ISS scores between the two groups before intervention. After intervention,the CRAMS score of the observation group was significantly higher than that of the control group (8.85±0.89 vs. 7.52±1.02,P<0.05),while the ISS score was significantly lower than that of the control group (15.98±2.98 vs. 20.77±3.02,P<0.05). The triage time,waiting time for treatment,and treatment time of the observation group were significantly shorter than those of the control group[triage time (minutes):3.25±0.62 vs. 5.89±1.02,waiting time for treatment (minutes):3.02±0.45 vs. 5.78±0.98,treatment time (minutes):45.85±5.23 vs. 65.22±6.41,all P<0.05]. Complication incidence of the observation group was significantly lower than that of the control group[3.75％ (3/80) vs. 12.50％ (10/80),P<0.05],while the satisfaction rate of the observation group was significantly higher than that of the control[93.75％ (75/80) vs. 77.50％ (62/80),P<005]. Conclusion The integrated graded diagnosis and rescue model based on CRAMS scores can improve the treatment efficiency of multiple trauma patients,improve their condition and prognosis,and enhance their satisfaction with treatment.
