Congenital lower urinary tract obstruction (CLUTO) is a spectrum of fetal malformations caused by anatomical abnormalities of the urethra, characterized by high rates of perinatal complications and mortality. The 2024 joint guideline from the European Association of Urology (EAU) and the European Society for Paediatric Urology (ESPU) introduced systematic revisions to the comprehensive management of CLUTO. Key updates encompass advancements in prenatal and postnatal screening and precise diagnosis, refined fetal prognosis assessment, clearer indications and modality selection for prenatal intervention, optimization of postnatal treatment strategies, and the establishment of a lifelong follow-up framework within an integrated care pathway. This article elucidates these key updates by comparing the 2024 EAU/ESPU guideline with the 2022 European Rare Kidney Disease Reference Network (ERKNet) consensus. It also discusses ongoing controversies and future research directions. The aim is to provide clinicians with the latest evidence-based insights to inform practice, ultimately improving outcomes and quality of life for children with CLUTO.

Objective:To describe the characteristics, etiology and patterns of outpatients and inpatients patients with moderate or severe valvular heart disease (VHD).Methods:This is a cross-sectional study. Outpatients and inpatients with moderate or severe VHD who underwent transthoracic echocardiography for first examination from 1 st January 2001 to 1 st January 2020 in Southwest Hospital, Army Medical University were enrolled. Data were collected from medical records and big data platform of Southwest Hospital. Characteristics of age and gender, etiology and types of VHD were descriptively analysed. Results:A total of 68 354 patients with moderate or severe VHD were enrolled. The age was 63 (50, 72) years. And 35 706 (52.24%) patients were female. (1) Age characteristics: There was similar age trend between male and female patients with moderate or severe VHD. The number of patients increased firstly and then decreased and reached its peak in the age group of 65-69 years old. The peak age of mitral stenosis patients was 45-49 years, which was earlier than that of whole patients with moderate or severe VHD. The median age of patients with bicuspid aortic valve was 42 years. (2) Gender characteristics: The proportion of tricuspid regurgitation, pulmonary regurgitation, mitral regurgitation, mitral stenosis and valve surgery in female patients with moderate or severe VHD were higher than those in male patients. The proportion of aortic regurgitation, aortic stenosis and bicuspid aortic valve in male patients with moderate or severe VHD were significantly higher than those in female patients (all P<0.05). (3) Etiology: The proportion of rheumatic VHD was 13.07% (8 934/68 354), which was higher than that of degenerative VHD (0.67% (458/68 354)). (4) Types of VHD: Tricuspid regurgitation made contribution to the largest proportion with 60.72% (41 503/68 354), followed by mitral regurgitation, aortic regurgitation, mitral stenosis, pulmonary regurgitation and aortic stenosis. Conclusions:There are certain regional characteristics in the prevalence of moderate or severe VHD in southwest China, suggesting different attention should be paid on the whole process of refined management of moderate or severe VHD.

Objective To understand the differences in the demand,preference,and tendency for elderly care services between urban and rural areas in the Pearl River Delta(PRD),and to provide reference for the planning and balanced allocation of elderly care resources in urban and rural areas.Methods Using the multi-stage stratified random sampling method,we selected 7 community health service centers in 2 prefecture-level cities in the PRD and conducted a questionnaire survey on the elderly care service demand,preference,and tendency among 1919 regular residents aged 60 years and above who attended the centers.Results A total of 641 urban elderly residents(33.4%)and 1278 rural elderly residents(66.6%)were surveyed in the PRD.The urban and rural elderly residents showed differences in the child number(χ2 =43.379,P<0.001),willingness to purchase socialized elderly care services(χ2 =104.141,P<0.001),and attitudes to the concept of raising child to avoid elderly hardship(χ2 =65.632,P<0.001).The proportion(71.8%)of rural elderly residents who prefer family-based elderly care was higher than that(57.1%)of urban elderly residents(χ2 =41.373,P<0.001).The proportion(62.2%)of urban elderly residents clearly expressing their willingness to choose institutions for elderly care was higher than that(44.0%)of rural elderly residents(χ2 =57.007,P<0.001).Compared with family-based elderly care,the willingness to choose institutional or community-based in-house elderly care was low among the urban elderly residents with surplus monthly household income or balanced income and expenditure;urban males,those with college education background or above,and those who purchased so-cialized elderly care services tended to prefer community-based in-house elderly care.In rural areas,the elderly residents who had local household registry were prone to choose institutional or community-based in-house elderly care,while those who had more than one child and those who were satisfied with the current living conditions were less willing to choose community-based in-house elderly care.Conclusions It is suggested that the urban-rural differences in the elderly care service demand,preference and tendency should be fully considered in the planning and allocation of urban and rural elderly care resources.Efforts remain to be made to develop diversified social elderly care services tailored to the characteristics of urban and rural areas.

Objective:To compare the clinical efficacy of rotator cuff repair combined with transposition of the long head of the biceps tendon in the treatment of massive rotator cuff tears with or without subscapularis injury.Methods:A total of 73 patients with massive rotator cuff tears who underwent arthroscopic rotator cuff repair combined with transposition of the long head of the biceps tendon in the Department of Upper Arm, Sichuan Orthopaedic Hospital from January 2019 to September 2022 were retrospectively analyzed, including 35 males and 38 females, aged 58.8±7.6 years (range, 46-73 years). There were 11 cases on the left side and 62 cases on the right side. Causes of injuries: 6 cases of car accidents, 13 cases of fall injuries, 54 cases of no obvious cause of injury. The patients were divided into subscapularis injury group (37 cases) and no subscapularis injury group (36 cases) according to the subscapularis injury or not. The visual analogue scale (VAS), Constant - Murley score, University of California Los Angeles (UCLA) shoulder score and range of motion were used to evaluate shoulder pain and functional improvement. MRI of the shoulder was taken at the final follow-up and the rotator cuff was assessed for retear using Sugaya grading.Results:All patients successfully completed the operation. The VAS score at 1 year postoperatively in the group without subscapularis injury was 0.58±0.87, which was less than 1.16±1.14 in the group with subscapularis injury ( t=-2.426, P=0.018). The Constant-Murley score and UCLA score at 1 year postoperatively in the group without subscapularis injury were 94.03±6.19 and 32.94±2.59, respectively, which were greater than those of the group with subscapularis injury, which were 86.51±11.96 and 30.38±3.33, and the difference was statistically significant ( P<0.05). Anterior flexion and body external rotation at 1 year postoperatively in the group without subscapularis injury were 137.22°±26.79° and 54.72°±13.20°, which were greater than those in the group with subscapularis injury of 121.08°±22.83° and 38.65°±17.19°, and the difference was statistically significant ( P<0.05), and the difference between the two groups in body internal rotation was not statistically significant ( P>0.05). The subacromial spacing at 1 year postoperatively was 9.4±1.3 mm in the group without subscapularis injury and 9.0±1.5 mm in the group with subscapularis injury, and the difference was not statistically significant ( t=1.318, P=0.192). There were 2 cases of rotator cuff retear 1 year after surgery without subscapular muscle injury and 5 cases of subscapular muscle injury. Conclusion:The clinical efficacy of arthroscopic rotator cuff repair combined with transposition of the tendon of the long head of the biceps tendon in the treatment of massive rotator cuff tears with or without subscapularis muscle injury is satisfactory, and the improvement of pain and function is more obvious in patients without subscapularis muscle injury.

Objective:To investigate the efficacy of 99Tc m-pyrophosphate (PYP) SPECT imaging for the differential diagnosis of transthyretin-related cardiac amyloidosis (ATTR-CA) and hypertrophic cardiomyopathy (HCM). Methods:Data of patients who were definitively diagnosed with ATTR-CA (35 patients (28 males, 7 females); age 62.5(58.6, 64.3) years) or HCM (14 patients (13 males, 1 female); age 60.5(57.3, 68.7) years) by extracardiac biopsy and echocardiography in the Second Xiangya Hospital of Central South University between June 2020 and March 2023 were retrospectively analyzed. All patients underwent planar and SPECT imaging 1 h after injection of 370-720 MBq 99Tc m-PYP. Visual scoring was performed (0-1 was negative, 2-3 was positive), and heart-to-contralateral lung uptake ratio (H/CL) was calculated based on planar images. The χ2 test was used to compare the difference in visual scores between ATTR-CA and HCM groups, and the diagnostic efficacy of the visual score was calculated. The H/CL differences between ATTR and HCM groups were compared with Mann-Whitney U test, and the ROC curve was used to analyze the efficacy of H/CL for the differential diagnosis of ATTR-CA and HCM. Results:There were 34 patients with visual scores≥2 and 1 patient with visual score<2 in the ATTR-CA group, 6 patients with visual scores =2 and 8 patients with visual scores <2 in HCM group, and there were significant differences between the 2 groups ( χ2=16.20, P<0.001). The diagnostic sensitivity of the visual score was 97.1%(34/35), and the specificity was 8/14. The H/CL in the ATTR-CA group was significantly higher than that in the HCM group (2.08(1.97, 2.20) vs 1.26 (1.17, 1.35), z=-5.09, P<0.001). The ROC curve analysis suggested that the optimal cut-off value was 1.45 (AUC: 0.980, 95% CI: 0.946-1.000; P<0.001); the sensitivity of H/CL differential diagnosis between HCM and ATTR-CA was 97.1%(34/35), and the specificity was 14/14. Conclusion:99Tc m-PYP SPECT imaging is useful in differentiation of ATTR-CA and HCM, and the optimal cut-off value of H/CL for differential diagnosis of these 2 diseases is 1.45.

Oxidative stress, due to the disruption of the balance between reactive oxygen species (ROS) generation and the antioxidant defense system, plays an important role in the pathogenesis of rheumatoid arthritis (RA). Excessive ROS leads to the loss of biological molecules and cellular functions, release of many inflammatory mediators, stimulate the polarization of macrophages, and aggravate the inflammatory response, thus promoting osteoclasts and bone damage. Therefore, foreign antioxidants would effectively treat RA. Herein, ultrasmall iron-quercetin natural coordination nanoparticles (Fe-Qur NCNs) with excellent anti-inflammatory and antioxidant properties were constructed to effectively treat RA. Fe-Qur NCNs obtained by simple mixing retain the inherent ability to remove ROS of quercetin and have a better water-solubility and biocompatibility. In vitro experiments showed that Fe-Qur NCNs could effectively remove excess ROS, avoid cell apoptosis, and inhibit the polarization of inflammatory macrophages by reducing the activation of the nuclear factor-κ-gene binding (NF-κB) pathways. In vivo experiments showed that the swollen joints of mice with rheumatoid arthritis treated with Fe-Qur NCNs significantly improved, with Fe-Qur NCNs largely reducing inflammatory cell infiltration, increasing anti-inflammatory macrophage phenotypes, and thus inhibiting osteoclasts, which led to bone erosion. This study demonstrated that the new metal-natural coordination nanoparticles could be an effective therapeutic agent for the prevention of RA and other diseases associated with oxidative stress.

Using machine learning algorithms to construct an early prediction model of brucellosis to improve the diagnosis efficiency of Brucellosis. This study was a case-control study. 2 381 brucellosis patients from Beijing Ditan Hospital affiliated to Capital Medical University were retrospectively collected as case group, and healthy people from Beijing Chaoyang Hospital affiliated to Capital Medical University were collected as control group from May 9, 2011 to November 29, 2021. The relevant clinical information and full blood count results of 13 257 data were collected and five algorithms of machine learning were used to construct an early predication model of brucellosis by using machine learning: random forest, Naive Bayes, decision tree, logistic regression and support vector machine;14 074 data (2 143 cases incase group and 11 931 cases in control group) were used to establish the early predication model of brucellosis, and 1 564 (238 cases in case group and 1 326 cases in control group) data were used to test the predication efficiency of the brucellosis model. The results showed that the support vector machine algorithm has the best predication performance by comparing the five machine learning models. The area under receiver curve (AUC) of receiver operating characteristic (ROC) was 0.991, and the accuracy, precision, specificity and Recall were 95.6%, 95.5%, 95.4% and 95.9%, respectively. Based on the SHAP plot, platelet distribution width (PDW) and basophil relative value (BASO%) results were low, and men with high coefficient of variation (R-CV), erythrocyte hemoglobin concentration (MCHC), and platelet volume (MPV) were predicted to be at high risk of brucellosis. Platelet distribution width (PDW) contributed the most to the prediction model, followed by red blood cell distribution width coefficient of variation (R-CV). In conclusion, the establishment of a high-precision early predication method of brucellosis based on machine learning may be of great significance for the early detection and treatment of brucellosis patients.

Objective:To investigate the efficacy and safety of green laser vaporization enucleation of the prostate with end-fire fiber in the treatment of benign prostatic hyperplasia.Methods:The clinical data of 218 patients with benign prostatic hyperplasia admitted to Zhejiang Provincial People's Hospital from August 2018 to July 2019 were retrospectively analyzed. All 218 patients presented symptoms of varying degrees of frequent voiding, urgency, nocturia, and progressive dysuria, with age of(76.2±8.4) years, prostate volume of(77.3±21.6) ml, and preoperative PSA of (3.5±0.9)ng/ml, preoperative maximum urine flow rate (Qmax)of(7.9±1.8)ml/s, residual urine volume of(82.3±26.3)ml, quality of life score(QOL) of(4.9±1.1)points, and International Prostate Symptom Score (IPSS) of (25.4±7.6) points. Lithotomy position was used intraoperatively, and intravenous combined general anesthesia or intraspinal anesthesia was performed before the green laser vaporization enucleation of the prostate. Intraoperatively, green laser equipment used a vaporization power of 80W, an optical fiber with a end-fire fiber of 800μm in diameter, and hemostasis power of 20W. The surgical procedure was firstly to vaporize and cut 3 grooves from the bladder neck to the ejaculatory hole plane of the prostate at 5, 7 and 12 o'clock, reaching deep enough to expose the surgical capsule, in order to set up" three lines and one side" anatomical landmarks. A combination of sheath peeling and vaporization cutting along the envelope layer was used to enucleate the hyperplastic glands according to the " three-leaf " method. After enucleation, the tissue was pushed into the bladder, and the enucleated tissue was crushed and aspirated with a tissue morcellation. Perioperative and postoperative parameters including vaporized enucleation time, tissue morcellation time, hemoglobin changes, bladder irrigating time, indwelling catheterization time, postoperative hospital stay, postoperative Qmax, residual urine volume, postoperative complications, IPSS and QOL were recorded. Urgency with involuntary urine leakage was diagnosed as urge incontinence, involuntary urine leakage after coughing was diagnosed as stress urinary incontinence, and the incontinence degree was defined according to the amount of pad used, with mild of 1-2 pads/day, moderate of 3-4 pads/day, and severe of 5 or more pads/day.Result:All 218 operations were successfully completed. Capsule perforation occurred in 8 cases(3.7%), and there was no bladder perforation. The time of vaporization and enucleation was (42.5±8.3)min, and the time of tissue morcellation was(12.1±3.4)min. The intraoperative and postoperative hemoglobin loss was(4.7±1.3)g/L, and there were no blood transfusion or re-operation for stopping bleeding. The average bladder irrigation time after operation was(6.3±1.6)h, the average indwelling catheterization time was(1.2±0.2)days, and the average postoperative hospital stay was (2.2±0.7)days. The Qmax 1 month after operation was(18.5±4.8) ml/s, and the residual urine volume of the bladder was(6.4±1.9)ml, which showed a statistical difference compared with the preoperative parameters( P<0.01). In addition, the QOL(2.1±0.4) and IPSS(7.1±2.1)showed a statistical difference at 3 months follow-up, compared with the parameters before or 1 month after the operation( P<0.01). The volume of the prostate at 3 months after the operation was(34.6±6.3) ml, and the PSA was(2.4± 0.5) ng/ml, which was statistically different from the preoperative corresponding parameters( P<0.01). During the follow-up within one year, 11 cases were detected incontinence during the 1-month follow up, including 6 cases of urge incontinence. After drug treatment, good continence achieved 3 months after the operation. The other 5 cases had stress urinary incontinence, 3 of whom got good continence after the drugs treatment and pelvic floor muscle exercise, and two patients recovered to one pad per day. A total of 24 cases of urethral stricture were found during the 12-month follow-up, including 16 cases of anterior urethral stricture, which was treated with 3 months of regular urethral dilation. Another 8 cases had bladder neck contracture, and were treated by bladder neck resection and regular urethral dilatation. All of them did not recur 6 months after the procedure. Conclusions:The end-fire green laser vaporization enucleation of the prostate has the advantages of short operation time, less intraoperative bleeding, and obvious improvement in postoperative symptom scores. The short-term effect is obvious, and the long-term effect still needs further study to confirm.

Objective:To conduct theoretical analysis and experimental research on peripherally inserted venous catheters, establish theoretical models of interaction between different materials catheters and simulated skin tissues, and test different catheters at the same time to provide theoretical basis and experimental basis for the optimization design.Methods:According to the mechanical properties of the catheter at 25 ℃ and 37 ℃, a finite element model of the catheter and simulate skin tissue was established. The relationship between catheter folds and material and structure during puncture was analyzed, and the stiffness, radiographic properties, etc. were tested experimentally.Results:The performance of the catheter at different temperatures is closely related to its material. The wrinkle situation of the catheter is related to the catheter material and the inclination of the wedge surface. The elastic modulus of the polyurethane (PU) catheter is about 500 MPa and 250 MPa, respectively at room temperature (25 ℃) and body temperature (37 ℃), which meets the clinical needs of high rigidity during puncture and soft material during indwelling. When the catheter structure is the same, the PU catheter is less prone to wrinkles than the fluorinated ethylene propylene copolymer (FEP) catheter. When the catheter material is the same, the smaller the inclination of the wedge surface, the less likely the catheter to wrinkle.Conclusions:Appropriately reducing the inclination of the wedge-shaped surface of the needle of peripherally inserted venous catheters can improve the success rate of puncture. The PU catheters have good mechanical properties, they are not prone to wrinkles during puncture, and their stiffness can be reduced at body temperature, which can not only increase the success rate of puncture, but also reduce the occurrence of complications. Therefore, PU catheters have a better clinical application prospect.
