OBJECTIVES: Stress urinary incontinence (SUI) is a common condition among women that severely impairs quality of life. Pelvic floor proprioceptive training (PFPT) has attracted increasing attention for its potential to enhance pelvic floor muscle function and alleviate SUI symptoms. This study aims to observe and compare the clinical efficacy of PFPT combined with electroacupuncture, electrical stimulation, and biofeedback therapy versus conventional therapy consisting of electroacupuncture, electrical stimulation, and biofeedback alone in women with SUI, and to explore the role of PFPT in improving symptom and functional outcomes. METHODS: In this randomized controlled trial, 72 women with mild to moderate SUI were recruited from the Department of Rehabilitation Medicine at Third Xiangya Hospital, Central South University, between December 2021 and October 2023. Participants were randomly assigned to an experimental group (n=36) or a control group (n=36). Both groups received health education. The control group underwent electroacupuncture combined with electrical stimulation and biofeedback therapy, while the experimental group additionally received PFPT 3 times per week for 4 weeks. The primary outcome was assessed using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Secondary outcomes included pelvic floor muscle strength, bladder neck mobility, and balance ability. The ICIQ-SF was reassessed at 1, 3, 6, and 12 months post-treatment. RESULTS: Both groups showed statistically significant improvements in all parameters after treatment (all P<0.05). However, there were no statistically significant differences between groups in most measures (all P>0.05). The experimental group demonstrated longer single-leg stance duration with eyes closed than the control group (left leg: P=0.026; right leg: P=0.006), with a significant increase from baseline (P<0.001). At 6 months post-treatment, the cure rate in the experimental group was significantly higher than that in the control group (P=0.037). CONCLUSIONS Conventional therapy effectively improves SUI symptoms, but adding PFPT provides notable additional benefits, including enhanced balance ability and sustained mid-term cure rates. These findings suggest that PFPT is a valuable adjunct to standard SUI management strategies.

Objective To investigate the predictive value of serum lactate dehydrogenase(LDH)level com-bined with high-throughput sequencing in children with severe Mycoplasma pneumoniae pneumonia(SMPP).Methods The clinical data of 99 children with Mycoplasma pneumoniae pneumonia(MPP)admitted to Hua-zhong University of Science and Technology Union Hospital from October 2023 to March 2024 were retro-spectively analyzed.According to the severity of the disease,the children were divided into mild group(33 ca-ses)and severe group(66 cases).Spearman correlation analysis was used for correlation analysis,Logistic re-gression was used to analyze the influencing factors of SMPP,and the receiver operating characteristic(ROC)curve was used to evaluate the value of LDH in predicting SMPP.Results The level of LDH in the severe group was higher than that in the mild group(P<0.05).The results of high-throughput sequencing showed that the proportions of virulence positive and drug resistance gene A2063G mutation in the severe group were higher than those in the mild group(P<0.05).Multivariate Logistic regression analysis showed that LDH level and drug resistance gene A2063G mutation were related to the SMPP(P<0.05).ROC curve analysis showed that LDH combined with high-throughput sequencing detection of drug resistance gene A2063G muta-tion had a high value in predicting SMPP,and the area under the curve was 0.724.Conclusion Serum LDH combined with high-throughput sequencing detection of drug resistance gene A2063G mutation can be used as an effective indicator to predict SMPP.

Trajectories refer to the motion paths followed by objects in space. Disease trajectories, which depict the evolution of disease processes over time, are significantly important for assessing diseases, formulating treatment strategies, and predicting prognosis. Critical illness is one of the leading causes of death. With advances in critical care medicine, there is increasing focus on the occurrence and development of critical illnesses. Understanding the development trajectory of critical illness is helpful to promote the early identification, intervention, and treatment of high-risk patients, avoid prolongation of the course of disease, reduce the risk of multiple organ failure, and provide important reference for the development of targeted prevention and intervention strategies, thereby reducing the incidence and mortality of critical illness. In recent years, various trajectory modeling methods have been applied to the study of critical illness. These include, but are not limited to, latent growth curve modeling (LGCM), growth mixture modeling (GMM), group-based trajectory modeling (GBTM), latent transition analysis (LTA), and latent class analysis (LCA). The aim of this article is to review the definition of disease trajectories, the methods used in trajectory modeling, and their applications and future prospects in critical illness research.

Objective:To investigate the intelligence status of children aged 10 - 12 in rural areas of Linxia Hui Autonomous Prefecture (referred to as Linxia) in Gansu Province.Methods:From September to November 2019, a cross-sectional study was carried out to investigate the intelligence status of children aged 10 to 12 in 8 counties (cities) of Linxia. Chinese Raven's Progressive Matrices (rural version) was used for intelligence test and children's intelligence quotient (IQ) was calculated by regular mold to evaluate children's intelligence level.Results:A total of 1 721 children in Linxia were tested for intelligence, with an average IQ of 103.2. Among them, low intelligence (≤69) accounted for 1.0% (18/1 721), borderline (70 - 79) accounted for 3.0% (52/1 721), middle and lower (80 - 89) accounted for 8.4% (144/1 721), moderate (90 - 109) accounted for 56.6% (974/1 721), middle and upper (110 - 119) accounted for 21.9% (377/1 721), excellent (120 - 129) accounted for 7.8% (135/1 721), extremely excellent (≥130) accounted for 1.2% (21/1 721). There were 635, 598 and 488 children aged 10, 11 and 12, respectively, with an average IQ of 106.1, 103.3 and 99.2. There were 919 males and 802 females, with an average IQ of 102.9 and 103.4, respectively.Conclusion:In 2019, the intelligence of children aged 10 to 12 in rural areas of Linxia has reached the moderate level.

Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is the main pathogen that causes COVID-19,which is fast-mutating and highly transmissible.The infection has led to a global epidemic.As the main preventive and control measure,vaccination plays a critical role in fighting a-gainst COVID-19.Although a large number of epitope-based and mucosal vaccines have been stud-ied,few peptide epitope vaccines targeting the mucosa and their functional evaluation have been re-ported.In this study,we used SARS-CoV-2 structural protein M peptide epitope predicted by the IEDB database as an antigenic target to design the MS-3S gene containing 3 050 and 1 229 signal peptides and DCpep optimized for insertion into MS2 phage coat proteins.The expression plasmid pSIP:MS-3S was constructed by cloning the PCR fragments seamlessly and was transformed into Lactiplantibacillus plantarum 18 to obtain the recombinant bacterium LP18:MS-3S.Expression conditions such as induction time,inducer concentration,rotational speed and initial pH were opti-mized.The intranasal immunization experiments were performed to examine the vaccine efficacy.The results showed that the 916 bp-long target gene MS-3S modified and optimized was amplified and used to successfully construct the recombinant bacterial strain LP18:MS-3S.The optimal con-ditions for recombinant protein expression were obtained and verified by Western blot,flow cy-tometry,immunofluorescence and other detection methods.The optimal expression conditions were determined as follows:induction time was 4 h with 100 pg/L of SppIP as the optimal induction concentration.Antibody-specific for the epitope was verified by ELISA experiments in serum,alve-olar lavage fluid and fecal dilutions of mice.In summary,a recombinant bacterial strain expressing the epitope antigen of the SARS-CoV-2 M protein peptide was constructed.The obtained protein can induce the body to produce humoral and mucosal immunity,which lays the foundation for the development of a vaccine candidate for the mucosal immunity of COVID-19.

Objective:To construct a hierarchical management model of performance objectives,and to explore its application value in the management of medical equipment procurement process.Methods:The procurement performance evaluation indicators were screened from the medical equipment procurement declaration level,process level,use level and disposal level,and the comprehensive evaluation model was developed by entropy weight method and data envelopment analysis(DEA)method to form the process management plan at the level of personnel,system,data and equipment.A total of 717 sets of medical equipment purchased by Beijing Youan Hospital from 2019 to 2022 were selected,and the conventional management mode(348 units)and hierarchical management mode(369 units)were used for management according to different performance objectives evaluation methods.The performance objectives achievement,the quality of procurement process management and the satisfaction of clinical allocation management of medical equipment procurement under different management modes were compared.Results:The 369 units of equipment under the hierarchical management model included operating room equipment,laboratory equipment,inpatient treatment equipment,disinfection supply equipment and other medical equipment,and the performance objectives achievement of the procurement were(96.10±3.46)%,(96.76±2.65)%,(95.59±2.52)%,(96.06±2.34)%and(96.88±1.75)%,respectively,which were higher than those of the management model,the difference was statistically significant(t=2.663,2.801,2.858,4.111,3.548,P＜0.05)The effective ratio of DEA in the comprehensive evaluation of the medical equipment procurement declaration level,process level,use level and disposal level under the hierarchical management model were 96.7%,98.6%,94.6%and 99.7%,respectively,which were higher than those of the conventional management model,the difference was statistically significant(x2=10.983,9.327,7.270,12.309,P＜0.05).The satisfaction of clinical departments with the procurement and use of medical equipment under the hierarchical management model were(95.82±2.83)%and(97.25±1.96)%,respectively,which were higher than those of the conventional management model,the difference was statistically significant(t=5.575,5.248,P＜0.05).Conclusion:The hierarchical management model can effectively implement the performance objectives of medical equipment procurement,improve the management quality of medical equipment procurement process,improve satisfaction of clinical departments and management personnel after procurement,and ensure the quality of equipment operation.

Objective:To explore the distribution characteristics of common clinical manifestations of elbow joint in patients with endemic fluorosis and their correlation with the influencing factors.Methods:A cross-sectional survey was conducted on all permanent adult residents in 13 endemic fluorosis villages in Gaotai and Gaolan counties of Gansu province. The survey included: ① Demographic information, family history, and current medical history. ② Physical examination specifically focued on the orthopedic clinical presentations. ③Taking DR films of the forearm (including elbow joint) and calf (including knee joint), and classify the elbow joint to grade K-L based on X-ray manifestations. ④ Measuring height and weight, and calculating BMI index. ⑤Applying the Mayo elbow joint rating scale to evaluate elbow joint function. Based on the survey results, the distribution characteristics of clinical symptoms and signs of elbow joint in patients with skeletal fluorosis, as well as the distribution characteristics and correlation of factors affecting elbow joint function such as age, gender, disease course, BMI, K-L grade, etc were described. The comparison of counting data and rates were analyzed with χ2 test or Fisher exact probability test. Pearson′s test was used for correlation analysis of continuous data that conforms to normal distribution, and Spearman test was used for non-normal distribution measurement and counting data. The correlation analysis of ordered hierarchical data was conducted using Kendall′s Tau- b test. Results:①Among 501 patients with skeletal fluorosis, a total of 465 cases (92.8%) were diagnosed with elbow joint pain. A total of 185 cases (36.9%) were with elbow joint tenderness, 300 cases (59.9%) were with elbow joint enlargement, 415 cases (82.8%) were with morning stiffness of the elbow joint, 102 cases (20.4%) were with cubital tunnel syndrome, 153 cases (30.5%) were with positive forearm extensor tendon traction test, and 97 cases (19.4%) were with positive forearm flexor tendon traction test. The detection rate of elbow joint rotation limitation was the highest among those with ROM ranging from 30 ° to 70 ° (261/501, 52.1%), and the detection rate of elbow joint extension and flexion limitation was the highest among those with ROM ranging from 50 ° to 90 °(274/501, 54.7%). ②Among 501 patients with skeletal fluorosis, a total of 465 cases were found to have symptoms and positive signs in the elbow joint, with the detection rate in males being lower than that in females, with a significant difference ( χ2=41.19, P<0.001). The majority of patients were between the ages of 50 and 65 (274/501, 58.9%), with a body mass index of <18 (217, 46.67%), K-L arthritis with a radiologic grade of Ⅲ (256/501, 55.0%), and a disease course of >30 years (217/501, 46.67%). ③The correlation between clinical characteristics, the Mayo score, and various influencing factors of skeletal fluorosis found a high correlation between pain and age ( r=0.79, P<0.001) and pain and disease course ( r=0.71, P<0.001). The ROM of extension and flexion was negatively correlated with age ( r=-0.43, P<0.001), K-L grade ( r=-0.67, P<0.001), and disease course ( r=-0.48, P<0.001); Elbow tunnel syndrome was positively correlated with age ( r=0.72, P<0.001). The Mayo functional score was negatively correlated with age ( r=-0.35, P<0.001). Conclusion:Early morning stiffness of the elbow joint (<30 min), limited rotation of the elbow joint, limited extension and flexion of the elbow joint, and cubital tunnel syndrome (degree Ⅰ) have a high detection rate in the population with skeletal fluorosis. Age, course of disease, and degree of joint degeneration have a significant impact on elbow joint function in patients with fluorosis.

Objective:To explore the long-term efficacy of laparoscopic fundoplication for proton pump inhibitor dependent gastroesophageal reflux disease (GERD).Method:Clinical data of proton pump inhibitor dependent GERD patients who underwent fundoplication at the Rocket Force Characteristic Medical Center from Jan to Jun 2012 were analyzed, including GERD symptom score, subjective symptom relief rate, PPI discontinuation rate and surgical satisfaction, as well as recurrence and complications.Result:A total of 160 GERD patients were included in this study, with 64% of patients having respiratory symptoms. Nissen and Toupet fundoplication were performed in 43 and 117 cases, respectively, with a follow-up time of (127±3) months. The postoperative GERD symptom scores of the patients were significantly lower than before treatment (all P<0.001); The subjective relief of overall symptoms in the digestive tract and airway problem was 90% (80%, 100%) and 100%, respectively. The PPI discontinuation rate was 86%, and the overall satisfaction rate of the treatment was 92%, and the satisfaction rate of patients with respiratory symptoms was 89%. 7% of patients experienced varying degrees of symptomatic recurrence, 4% of patients re-underwent endoscopic treatment and/or laparoscopic fundoplication due to symptom recurrence. The incidence of long-term postoperative dysphagia, bloating, belching, increased exhaust, abdominal pain, diarrhea, and constipation were 11.3%, 16.9%, 0, 1.3%, 0, 2.5%, and 5.6%, respectively. Conclusions:Laparoscopic fundoplication has good long-term efficacy in the treatment of GERD. A small number of patients may experience postoperative recurrence, as well as complications such as dysphagia and gas-bloat syndrome. Most recurrent patients can achieve good therapeutic effect by redoing endoscopic treatment or redoing surgery.

Goniotomy (GT) is a safe and effective type of minimally invasive glaucoma surgery (MIGS) extensively utilized in China.It is particularly suited for treating primary open-angle glaucoma and advanced primary angle-closure glaucoma.Although GT is generally safe, hyphema and postoperative intraocular pressure (IOP) spikes remain common complications after GT.Currently, there is no standardized protocol for managing these issues, which can impact clinicians' assessment of surgical outcomes and potentially affect the prognosis.Therefore, it is crucial to establish comprehensive and detailed management protocols for perioperative hyphema and IOP spike following GT.This will guide clinical practitioners in managing complications appropriately and systematically, thereby promoting the further development and refinement of MIGS.To address these concerns, several domestic glaucoma treatment experts along with members of the Glaucoma Society of Ophthalmology, Guangdong Medical Association reviewed existing literature and held recommendation meetings to develop a guideline for managing perioperative hyphema and IOP spikes following GT.It includes defining perioperative hyphema in GT, discussing its high-risk factors and outcomes, exploring methods for prevention prior to surgery and techniques to reduce bleeding during the procedure, and managing postoperative hemorrhage.Additionally, it covers defining IOP spikes after GT, investigates their causes and contributing factors, and outlines management strategies and anticipated outcomes to provide a valuable resource for clinicians.

Objective To investigate the correlation between serum long non-coding RNA FGD5-AS1(ln-cRNA FGD5-AS1),microRNA-103a-3p(miR-103a-3p)and puerperal infection(PI)in patients with gesta-tional diabetes mellitus(GDM)in late pregnancy.Methods A total of 168 late pregnancy GDM patients who were hospitalized and delivered in the hospital from January 2022 to June 2023 were retrospectively selected as the experimental group,and the patients were separated into an infected group(96 cases)and an uninfected group(72 cases)based on whether they had PI.At the same time,120 late pregnant women who underwent prenatal examination in the hospital and had normal gestational blood glucose were selected as the control group.Real-time fluorescence quantitative PCR(qRT-PCR)was applied to detect the expression levels of ln-cRNA FGD5-AS1 and miR-103a-3p.Multivariate Logistic regression was applied to analyze the influencing factors of PI in late pregnancy GDM patients.StarBase website was applied to analyze the relationship between lncRNA FGD5-AS1 and miR-103a-3p.Pearson was applied to analyze the correlation between lncRNA FGD5-AS1 and miR-103a-3p.Receiver operating characteristic(ROC)curve was applied to evaluate the value of ln-cRNA FGD5-AS1 and miR-103a-3p in predicting the occurrence of PI.Results There was a statistically sig-nificant difference in the expression levels of serum lncRNA FGD5-AS1 and miR-103a-3p between the experi-mental group and the control group(P＜0.05),the expression level of serum lncRNA FGD5-AS1 in the infec-ted group was obviously higher than that in the uninfected group(P＜0.05),but the expression level of ser-um miR-103a-3p in the infected group was obviously lower than that in the uninfected group(P＜0.05).The expression level of lncRNA FGD5-AS1 was an independent risk factor for PI in late-pregnancy GDM patients(P＜0.05),and the expression level of miR-103a-3p was an independent protective factor for PI in late-preg-nancy GDM patients(P＜0.05).There was a negative correlation between lncRNA FGD5-AS1 and miR-103a-3p expression level(r=-0.409,P＜0.001).The efficacy of the combined detection of lncRNA FGD5-AS1 and miR-103a-3p for predicting PI in late pregnancy GDM patients was superior to that of serum lncRNA FGD5-AS1 and miR-103a-3p alone(P＜0.05).Conclusion LncRNA FGD5-AS1 is an independent risk factor for PI in late pregnancy GDM patients,while miR-103a-3p is an independent protective factor for PI in late pregnancy GDM patients.The combined detection has higher value for predicting PI in late pregnancy GDM patients.
