Objective To explore the efficacy and safety of converting the triple immunosuppressive regimen of tacrolimus (Tac) + mycophenolate mofetil (MMF) + prednisone (Pred) to a quadruple regimen of low-dose sirolimus (SRL) + low-dose Tac + MMF + Pred at 3 to 6 months after expanded criteria donor (ECD) kidney transplantation. Methods A single-center, retrospective, donor-matched controlled study included 22 ECD kidney transplant recipients from September 2021 to June 2024. Two recipients from the same donor kidneys were respectively assigned to the SRL group and the conventional triple regimen control group. The main outcome measures were the differences in serum creatinine (Scr), estimated glomerular filtration rate (eGFR), and adverse events before the regimen conversion and after conversion during the 1, 3, 6, and 12-month follow-up. Results There were no statistically significant differences in baseline characteristics between the two groups. In the SRL group, Scr decreased and eGFR increased starting from 3 months after conversion, and this was superior to the control group starting from 6 months(all P < 0.05). There were no statistically significant differences in the incidence of rejection reactions, pulmonary infections, hyperlipidemia and proteinuria between the two groups after conversion and during the 12-month follow-up (all P > 0.05). Conclusions For ECD kidney transplant recipients, converting the triple regimen to the SRL quadruple regimen at 3 to 6 months after transplantation may improve the function of the transplanted kidney without increasing the risk of adverse events.

Esophageal cancer is a prevalent malignant tumor of the digestive tract in China, and radical surgery remains the cornerstone of its comprehensive treatment. However, multifactorial challenges such as postoperative gastrointestinal tract reconstruction, traumatic stress, and tumor-related metabolic disturbances render esophageal cancer patients highly susceptible to malnutrition. Perioperative nutritional support therapy plays a crucial role in enhancing surgical safety, improving clinical outcomes, and elevating patients' quality of life by regulating metabolic homeostasis, preserving organ function, and optimizing the immune microenvironment. This article reviews the mechanisms underlying malnutrition in esophageal cancer, methods for nutritional status assessment, and precision intervention pathways based on multi-omics evaluations. The aim is to strengthen clinicians' awareness of standardized perioperative nutritional management for esophageal cancer patients and promote its clinical implementation, thereby facilitating postoperative recovery and improving long-term quality of life.

Objective To systematically analyze the literature characteristics of Journal of Organ Transplantation since its inception. Methods Using the China National Knowledge Infrastructure (CNKI) academic journal full-text database as the data source, all articles published in the Journal of Organ Transplantation from January 2010 to August 2025 were retrieved. After excluding non-academic papers, a total of 1 568 research papers were included. R language 4.3.0, Bibliometrix package 3.2.1, and Citespace software were used to analyze the number of publications, publishing institutions, authors, keywords and other aspects. Results The number of publications in Journal of Organ Transplantation increased from an average of 82 articles per year in the early years after its inception to 113 articles per year in recent years, a growth of 37.8%. The geographical distribution of publishing institutions covers 32 provinces, cities and autonomous regions nationwide, mainly concentrated in the South China, East China and North China regions, and has now basically covered the central and western regions in recent years. The author collaboration network includes 45 authors distributed across 7 major collaboration clusters, forming a stable multi-level national research system centered on key university-affiliated hospitals. The high-frequency keywords are dominated by "liver transplantation" (425 times) and "kidney transplantation" (396 times). The theme evolution shows a clear three-stage characteristic: initially focusing on clinical technology application, deepening to immune mechanism exploration in the middle stage, and recently (since 2022) focusing on cutting-edge research areas such as xenotransplantation. Conclusions Journal of Organ Transplantation has witnessed the rapid development of China's organ transplantation cause, fully reflecting the research status and trends in China's organ transplantation field, and has provided an important platform for the future development and international cooperation in China's organ transplantation field.

Objective To investigate the etiology and treatment of dysuria shortly after holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH), so as to improve the therapeutic efficacy. Methods A retrospective analysis was conducted on 1361 BPH patients who received HoLEP at our hospital during Mar. 2018 and Mar. 2025. All patients underwent ultrasound, computed tomography (CT), urethral probing or radiography, cystourethroscopy, and urodynamic testing. The causes, treatments and prognosis of dysuria after operation were summarized. Results ninety-eight patients (7.2%) experienced dysuria within 3 months after surgery, and all patients received initial urethral dilation. Among the 62 cases with urethral stricture, 28 were treated with urethral dilation (average of 8 sessions), 16 underwent external urethral incision, 8 underwent anterior urethroplasty, and 10 underwent transurethral plasma incision for urethral stricture. Of the 12 cases with residual prostate tissue, 5 underwent urethral plasma prostatectomy and 7 received medication. All of the 12 cases with bladder neck contracture underwent transurethral plasma incision of the bladder neck and local drug injection. Five cases with intravesical blood clots underwent urethral blood clot irrigation, 2 of which developed active bleeding and then underwent electrocoagulation. Four cases with detrusor dysfunction had catheters re-indwelled for one week followed by medication. Two cases with stone and one case with tissue fragment impacted in the urethra underwent urethral holmium lithotripsy and cystoscopic removal. All patients underwent reoperation successfully and experienced complete resolution or significant improvement of urinary difficulties. Conclusion A certain proportion of patients experience dysuria after HoLEP, with diverse etiologies. The combination of prevention and treatment can reduce the incidence of dysuria.

ObjectiveTo systematically screen and validate key immunogenic cell death （ICD）-related genes that play important roles in primary sjögren’s syndrome （pSS） using multi-omics data. MethodsGene expression profiles of pSS patients and healthy controls （GSE66795， 131pSS patients/29 healthy controls） were obtained from the Gene Expression Omnibus （GEO） database. Candidate genes were selected by intersecting these profiles with known ICD core gene sets and pSS-related targets. The CIBERSORT algorithm was used to analyze immune cell infiltration characteristics. Validation of gene expression was performed using transcriptomic data from sorted CD8⁺ T cell subsets （GSE93683）. Finally， labial gland tissues and peripheral blood samples from 10 pSS patients and 4 healthy controls were collected， and key genes were experimentally validated by reverse transcription quantitative polymerase chain reaction （RT-qPCR）. ResultsSeven intersecting genes from the ICD-differentially expressed genes （DEGs）-pSS intersection were identified ［caspase 1 （CASP1）， forkhead box P3 （FOXP3）， interferon-gamma （IFNG）， myeloid differentiation primary response 88 （MYD88）， toll-like receptor 7 （TLR7）， DExD/H-box helicase 58 （DDX58）， and interferon induced helicase C domain 1 （IFIH1）］. Immune infiltration analysis showed that in pSS labial gland tissues， the proportions of naïve B cells and dendritic cells significantly increased， while the proportions of resting NK cells and M0 macrophages decreased （P<0.05）. Transcriptomic data of CD8⁺T cell subsets indicated that IFIH1 expression was significantly elevated in central memory CD8⁺T cells （P<0.05）. RT-qPCR experimental validation revealed that DDX58， IFIH1， and CASP1 were significantly upregulated in both peripheral blood leukocytes and labial gland tissues of pSS patients （all P<0.05）， whereas IFNG expression increased in peripheral blood but decreased in labial gland tissues （P<0.05）. ConclusionThis study identified and confirmed DDX58， IFIH1， CASP1， and IFNG as key ICD-related genes in pSS through a combination of bioinformatics and experimental validation， providing new candidate targets for further understanding the immunopathological mechanisms of pSS.

China emerges as a major country in nuclear energy development and the application of nuclear and radiologic technology. The diagnosis and treatment of acute radiation syndrom (ARS) caused by external irradiation represent a core function in the country′s medical rescue of nuclear and radiological emergencies. Clinically, ARS manifests hematopoietic, gastrointestinal, cutaneous, and central nervous system syndromes, with specific clinical manifestations, signs, severity, and prognosis strongly correlated with radiation dose. China has established a number of national and provincial centers for treating radiation-induced damage. Nevertheless, most medical staff have limited experience in ARS treatment. This consensus presents a summary of recent experience in treating ARS of China. In combination with recommendations from international organizations such as the World Health Organization (WHO), this consensus proposes key evidence of critical clinical issues of ARS, covering all links in the rescue of external irradiation-induced ARS. Initially, clinical diagnosis, syndromes, and severe degrees should be determined based on clinical symptoms and dose estimates. It is necessary to normalize clinical treatment measures for hematopoietic recovery, gastrointestinal injury treatment, infection control, symptomatic treatment, and multi-organ function preservation. To this end, this consensus offers cautions. This consensus provides principles of treatment with traditional Chinese medicine, psychological intervention, and follow-up. Additionally, it highlights multidisciplinary collaboration. It is recommended that this consensus be applied in relevant treatment centers.

Objective:To investigate the situation of mild cognitive impairment (MCI) in elderly people in fluorosis areas, and analyze its potential influencing factors.Methods:From April to October 2020, a cluster random sampling method was used to select local elderly people aged 60 and older in areas of drinking-water-borne endemic fluorosis in Tianjin, and their general information was collected through face-to-face surveys. Terminal drinking water samples were collected from survey subjects. Water fluoride concentration was measured using ion-selective electrode method. Cognitive function was evaluated using the Mini-Mental State Examination (MMSE), and survey subjects were categorized into MCI group and control group based on MMSE scores. Logistic regression and Chi-squared automatic interaction detection classification tree models were constructed to analyze the influencing factors of MCI.Results:A total of 677 subjects were included, including 160 cases in the MCI group and 517 cases in the control group, with a MCI detection rate of 23.63%. The detection rates of MCI in the high fluoride exposure group and non high fluoride exposure group were 30.82% (94/305) and 17.74% (66/372), respectively, with a statistically significant difference between the groups (χ 2 = 15.88, P < 0.001). The results of univariate analysis showed that MCI was associated with high fluoride exposure, age, per capita annual household income, sleep duration, personality, and interpersonal relationships (χ 2 = 15.88, 16.17, 12.32, 8.91, 14.03, 9.81, P < 0.05). The results of multiple logistic regression analysis showed that moderate interpersonal relationships ( OR = 2.13, 95% CI: 1.08, 4.20) and high fluoride exposure ( OR = 1.91, 95% CI: 1.03, 3.54) were both risk factors for MCI ( P < 0.05). The classification tree model analysis result showed that high fluoride exposure was the primary factor affecting MCI in elderly people in fluorosis areas, followed by per capita annual household income, personality, and age. Conclusions:The detection rate of MCI in the high fluoride exposure group of elderly people in fluorosis areas is higher than that in the non high fluoride exposure group. High fluoride exposure, interpersonal relationships, per capita annual household income, personality, and age are all influencing factors of MCI in elderly people in fluorosis areas.

Objective:To learn about the iodine nutrition status of pregnant women in Tianjin and analyze the influencing factors of moderate to severe iodine deficiency in pregnant women.Methods:From January 2022 to December 2024, a stratified random sampling method was adopted. Each year, five sampling areas were divided into the east, west, south, north and central directions in 16 districts of Tianjin. Ten pregnant women from one township/street in each area were selected for questionnaire surveys. Household salt samples and random urine samples were collected to measure salt iodine and urinary iodine levels. Multivariate logistic regression was used to analyze the influencing factors of moderate to severe iodine deficiency in pregnant women, and a restricted cubic spline model was used to analyze the dose-response relationship between the risk of moderate to severe iodine deficiency in pregnant women and salt iodine level.Results:A total of 2 532 pregnant women in Tianjin were surveyed, with an age of (30.70 ± 4.44) years. Among them, 53.20% (1 347/2 532) had received health education, and 52.45% (1 328/2 532) actively supplemented iodine. A total of 2 532 household salt samples of pregnant women were tested, with a median salt iodine level of 23.66 mg/kg. The coverage rate of iodized salt was 74.45% (1 885/2 532), the qualified rate of iodized salt was 87.59% (1 651/1 885), and the consumption rate of qualified iodized salt was 65.21% (1 651/2 532). A total of 2 532 urine samples of pregnant women were tested, with a median urinary iodine level of 151.68 μg/L. Among them, 652, 1 348 and 532 urine samples were collected from pregnant women in the early, middle, and late stages of pregnancy, respectively, with median urinary iodine levels of 150.80, 153.00 and 143.68 μg/L, respectively. Multivariate logistic regression analysis showed that consuming iodized salt was a protective factor for the moderate to severe iodine deficiency in pregnant women ( OR = 0.70, 95% CI: 0.58 - 0.86, P < 0.001). Restricted cubic spline analysis showed that there was a linear dose-response relationship between the risk of moderate to severe iodine deficiency in pregnant women and salt iodine level ( Poverall < 0.001, Pnonlinear = 0.065). Further stratified analysis revealed that there was a linear dose-response relationship between the risk of moderate to severe iodine deficiency in pregnant women who had received iodine supplementation and salt iodine level ( Poverall = 0.018, Pnonlinear = 0.554), while there was a nonlinear dose-response relationship between the risk of moderate to severe iodine deficiency in pregnant women who had not received iodine supplementation and salt iodine level ( Poverall < 0.001, Pnonlinear = 0.029). Conclusions:From 2022 to 2024, the overall iodine level of pregnant women in Tianjin is appropriate, but some pregnant women are at risk of iodine deficiency. Consuming iodized salt is a protective factor against the moderate to severe iodine deficiency in pregnant women. It is still necessary to further implement comprehensive prevention and control measures mainly based on iodized salt.

Objective:To investigate the prevalence of dental fluorosis in children in Tianjin and study its influencing factors.Methods:From January to December 2023, 5 affected villages were selected from each of the drinking water-borne endemic fluorosis (drinking water-borne fluorosis for short) areas of 10 agricultural areas in Tianjin, and 50 children aged 8 - 12 years (gender and age balanced) were selected from each affected village for questionnaire survey and dental fluorosis examination. At the same time, water samples from affected villages and children's one random urine sample were collected to test for fluoride levels in water and urine. Multivariate logistic regression was used to analyze the influencing factors of dental fluorosis prevalence in children, and a restricted cubic spline model was used to analyze the dose-response relationship between the years of water improvement and dental fluorosis prevalence.Results:A total of 50 water samples were collected, with water fluoride levels ranging from 0.05 to 0.85 mg/L. All affected villages had completed the water improvement and the water fluoride levels were qualified. A total of 2 439 urine samples were collected from children, with urinary fluoride levels ranging from 0.05 to 12.56 mg/L and a geometric mean of 0.82 mg/L. A total of 2 439 children were examined for dental fluorosis, with a detection rate of 22.67% (553/2 439). The results of multivariate logistic regression analysis showed that age ( OR = 1.26, 95% CI: 1.15 - 1.37, P < 0.001), father's education level of junior high school or below ( OR = 1.57, 95% CI: 1.04 - 2.38, P = 0.033), and high urinary fluoride (0.74 - 1.58 mg/L: OR = 1.59, 95% CI: 1.19 - 2.13, P = 0.002; 1.59 - 12.56 mg/L: OR = 2.00, 95% CI: 1.48 - 2.70, P < 0.001) were risk factors for dental fluorosis prevalence in children. The total annual household income with 40 000 to 80 000 yuan ( OR = 0.76, 95% CI: 0.58 - 0.99, P = 0.041), father's occupation was self-employed and other occupation ( OR = 0.69, 95% CI: 0.51 - 0.92, P = 0.013), the years of water improvement in affected villages ≥10 years ( OR = 0.39, 95% CI: 0.30 - 0.50, P < 0.001), and the material of the drinking water container at home was stainless steel products ( OR = 0.58, 95% CI: 0.40 - 0.85, P = 0.005), ceramic or glass products ( OR = 0.66, 95% CI: 0.48 - 0.90, P = 0.010) were protective factors for dental fluorosis prevalence in children. By constructing a restricted cubic spline model, it was found that there was a linear dose-response relationship between the prevalence of dental fluorosis in children and the years of water improvement in affected villages ( Poverall < 0.001, Pnonlinear = 0.059). The longer the years of water improvement, the lower the risk of dental fluorosis prevalence. Conclusions:The detection rate of dental fluorosis in children in Tianjin is relatively high. The fluoride reduction and water improvement measures implemented in drinking water-borne fluorosis areas can effectively reduce the risk of dental fluorosis prevalence. Factors such as age, urinary fluoride, economic conditions, and lifestyle also have important impacts on the prevalence of dental fluorosis.

Objective:To investigate the awareness of prevention and treatment knowledge of drinking water-borne endemic fluorosis among children in Tianjin, explore its influencing factors, analyze the needs of children's health education methods, and provide a basis for carrying out health education in school.Methods:From January to December in 2024, a stratified sampling method was employed to select two endemic villages from each of the 10 areas with drinking water-borne endemic fluorosis in Tianjin as survey sites. In each village, no fewer than 50 children aged 8 - 12 (gender and age balanced) were recruited to conduct a questionnaire survey. Multivariate logistic regression analysis was used to analyze the influencing factors of children's awareness of prevention and treatment knowledge.Results:A total of 1 678 valid questionnaires were collected. The overall awareness rate of prevention and control knowledge of drinking water-borne endemic fluorosis among children in Tianjin was 67.62% (11 346/16 780). Children had the highest awareness of the hazards of drinking water-borne endemic fluorosis (83.61%, 1 403/1 678), while their awareness of the clinical manifestations of dental fluorosis was the lowest (44.87%, 753/1 678). Multivariate logistic regression analysis showed that children in higher grades [grades 5 to 6, OR (95% CI) = 1.66 (1.36, 2.03), P < 0.001], with a larger number of permanent residents in the family [≥6 people, OR (95% CI) = 1.58 (1.13, 2.23), P = 0.008], whose mothers had a college education or above [ OR (95% CI) = 1.45 (1.08, 1.95), P = 0.014], and who had received health education [ OR (95% CI) = 1.46 (1.19, 1.78), P < 0.001] had a higher awareness rate of the prevention and control knowledge of drinking water-borne endemic fluorosis. There were statistically significant differences in the demand rates for access to prevention and control knowledge via school teachers, promotional videos, and online/WeChat official accounts among children of different grades ( P < 0.05). Conclusions:The awareness rate of prevention and treatment knowledge of drinking water-borne endemic fluorosis among children in Tianjin is relatively low. Special attention should be paid to children with a small number of permanent residents in the family, mothers with low educational levels, and who have not received health education. At the same time, detailed health publicity services should be carried out for children of different grades.
