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.

Background/Aims: Liver transplantation (LT) following total hepatectomy is a life-saving treatment for hepatocellular carcinoma (HCC). The HCC recurrence after LT hinders the effectiveness of the procedure. The objective of this study is to develop a pre-operative risk stratification model based on a liquid biopsy. Methods: We conducted a comprehensive multi-omics study of 260 HCC patients from three centers, including clinical data, low-coverage whole-genome sequencing of cell-free DNA (cfDNA) from plasma, as well as whole-exome, single-nucleus RNA, and spatial transcriptomics from matched tumor and non-tumor tissues. Results: We identified cfDNA-derived copy number alteration (CNA) signatures associated with post-transplant recurrence. By integrating cfDNA-derived CNA profiles with single-cell transcriptomic data, we traced recurrence-associated cfDNA to a distinct subpopulation of malignant cells within the primary tumor. These cells were embedded in a pro-metastatic microenvironment of specialized endothelial subtypes and cancer-associated fibroblasts. Notably, most recurrence-associated lesions were detectable in cfDNA prior to liver transplantation (LT). Building on these insights, we developed the ZJU Criteria based on CNA fragments and tumor markers, a pre-LT risk prediction tool that integrates conventional clinical factors with cfDNA-derived CNA signatures, and validated it using internal and independent external cohorts. Conclusion Our findings suggest that post-transplant recurrence commonly originates from advanced subclones that emerge late during tumor evolution. The ZJU Criteria provides an accurate, non-invasive strategy that significantly improves pre-LT risk stratification and clinical decision-making for patients with HCC.

Objective To identify renal function and other readily accessible indicators influencing the prognosis of renal cell carcinoma (RCC) patients after nephrectomy, and to construct a prognostic prediction model based on them. Methods The clinical and pathological data of 624 RCC patients undergoing radical or partial nephrectomy in the First Hospital of Shanxi Medical University during Jan. 2013 and Dec. 2021 were retrospectively analyzed. The independent prognostic factors affecting postoperative overall survival (OS) were identified with LASSO algorithm combined with Cox regression analysis. Based on these factors, a nomogram was constructed to predict the 1-, 3-, and 5-year survival rates. The performance of the model was evaluated using the concordance index (C-index), time-dependent receiver operating characteristic (ROC) curves and the area under the curve (AUC), calibration plots, and decision curve analysis (DCA). Finally, the cutoff value of the nomogram was calculated to stratify patients into risk groups. Kaplan-Meier survival analysis with log-rank testing was performed to compare outcomes between the risk groups. Results Nine independent prognostic factors were identified, including age, smoking history, diabetes mellitus history, maximum tumor diameter, tumor subtype, N stage, Fuhrman grade, preoperative serum creatinine and cystatin C (P＜0.05). The nomogram achieved a C-index of 0.891, with time-dependent AUC of 0.920, 0.903, and 0.867 for 1-, 3-, and 5-year OS, respectively. Calibration curves showed excellent agreement with actual observations, and DCA demonstrated significant clinical net benefits across a wide threshold probability range. Using a cutoff score of 110.4, Kaplan-Meier analysis revealed statistically significant survival differences between risk groups (P＜0.001). Conclusion The proposed nomogram, incorporating renal function and other readily accessible clinical indicators, exhibits strong predictive accuracy for postoperative survival in RCC patients and may serve as a practical tool for individualized clinical decision-making.

Objective To explore the effect of the preservation of infrapatellar fat pad on pain,incision healing and function recovery in patients with knee osteoarthritis after joint replacement.Methods The clinical data of 127 patients with knee osteoarthritis who underwent joint replacement in the hospital from June 2019 to September 2022 were retrospectively collected.According to the preservation of infrapatellar fat pad,the subjects were divided into a control group(removing infrapatellar fat pad,67 cases)and an observation group(preserving infrapatellar fat pad,60 cases).The changes in length of patellar tendon,pain,knee function and range of motion were analyzed.The occurrence of adverse reactions was statistically analyzed.Results At 12 months after surgery,the length of patellar tendon was reduced.The length of patellar tendon in observation group[(38.8±6.24)mm]was longer than that in control group[(36.2±6.71)mm](P＜0.05).Observation group of patellar tendon length rate is lower than the control group[(4.1±1.18)％vs(10.7±3.01)％],there was statistical significance between the two groups(P＜0.05).Pain in both groups was alleviated at 1 month,3 months,6 months and 12 months after surgery.The changes in observation group were greater than those in control group(P＜0.05).During follow-up,the incidence of adverse reactions in observation group(6.67％)was lower than that in control group(14.93％)(P＞0.05).The range of motion and function of knee joint were improved at 12 months after surgery,and the improvement in observation group was greater than that in control group(P＜0.05).Conclusion Preserving infrapatellar fat pad is more beneficial to relieving postoperative pain and restoring knee function in patients with knee osteoarthritis after joint replacement.Therefore,the intact infrapatellar fat pad should be preserved as possible in clinical practice.

Hyperuricemia is a chronic metabolic disease resulting from purine metabolic dysfunction and is classified under the category of"blood turbidity"in traditional Chinese medicine.Our team termed it"acid turbidity,"and its pathogenesis is closely related to the dynamic evolution of the clear and the turbid components.With the change of modern people's diet structure,the incidence of hyperuricemia is increasing annually owing to the intake of fatty,sweet foods and alcohol.Therefore,this paper explores hyperuricemia from the"indigestion of spleen and stomach"theory.The core pathogenesis of hyperuricemia is indigestion of spleen and stomach,the inversion of clear and turbid substances,and endogenous acid turbidity.The initial manifestation of hyperuricemia is the internal retention of acid turbidity and ascending-descending disharmony;the gradual manifestation of this disease is that indigestion causes heat,and acid turbidity transforms into poison;the final manifestation of this disease is that secular indigestion causes deficiency and the inversion of clear and turbid substances.It can be summarized into three syndromes:syndromes of internal retention of dampness-turbidity,dampness-heat toxin amassment,and dampness-heat due to spleen deficiency.Therefore,this paper proposes to treat the disease according to different syndromes,with ascending the clear and descending the turbid as the core of treatment.And the therapeutic approach employs the flexible application of three methods:transportation,resolving,and transformation.For syndrome of internal retention of dampness-turbidity,treatment focuses on promoting spleen transportation to eliminate dampness;for syndrome of dampness-heat toxin amassment,the strategy is to resolve indigestion and purge heat;and for syndrome of dampness-heat due to spleen deficiency,the aim is to resolve turbidity and clear heat.By ascending the clear and descending the turbid,so that"returning the clear and the turbid to the original,"the spleen and stomach regain harmony,functions of ascending and descending are reestablished,and hyperuricemia can be effectively managed.

Objective:To explore the latent categories of barriers to PhaseⅡ cardiac rehabilitation in patients after coronary artery bypass grafting (CABG), and to analyze the influencing factors of different latent classes.Methods:A total of 340 CABG patients in PhaseⅡ cardiac rehabilitation were recruited by convenience sampling from two Class Ⅲ Grade A hospitals in Shanghai between January and August 2024. Data were collected using a general information questionnaire, the Cardiac Rehabilitation Barriers Scale (CRBS), and the Fear of Exercise Scale for Cardiac Patients. Latent profile analysis was used to classify the cardiac rehabilitation barriers, and multinomial Logistic regression was conducted to identify influencing factors for different latent classes.Results:Of the 340 questionnaires distributed, 319 valid responses were obtained after excluding incomplete or patterned questionnaires, with a valid response rate of 93.82% (319/340). The cardiac rehabilitation barriers among the 319 CABG patients were classified into three latent profiles: low-barrier, active rehabilitation type; moderate-barrier, poor-functioning type; and moderate-barrier, insufficient-perception type. Multinomial logistic regression analysis indicated that smoking, comorbidities, age, educational level, and fear of exercise were statistically significant influencing factors for different barrier profiles ( P<0.05) . Conclusions:Cardiac rehabilitation barriers in CABG patients exhibit heterogeneity. Medical staff should adopt targeted intervention strategies based on the specific barrier profiles, reduce patients' fear of exercise, and thereby improve rehabilitation outcomes.

Objective:To compare bowel function 12 months after surgery between side-to-end anastomosis (SEA) and end-to-end anastomosis (EEA) groups of patients who had undergone rectal cancer resection.Methods:This single-center, prospective, open-label, phase III randomized controlled trial was approved by the Ethics Committee of Peking University People's Hospital (2018PHB040-01) and registered at ClinicalTrials. org (NCT03669237). Inclusion criteria were as follows: (1) histologically confirmed rectal adenocarcinoma; (2) tumor located 0 to 12 cm from the anal verge; (3) age≥18 years; and (4) planned R0 resection with primary reconstruction. Exclusion criteria included: (1) emergency surgery; (2) cognitive impairment; (3) non-primary anastomosis; (4) history of left-sided colonic or anorectal surgery; and (5) preexisting chronic defecation dysfunction. Eligible rectal cancer patients scheduled for elective sphincter-preserving surgery at Peking University People's Hospital were prospectively enrolled between October 2018 and March 2021 and randomly assigned to either the EEA group or the SEA group via computer-generated numbers prior to entering the operating room. All patients underwent standard radical tumor resection. Bowel function was evaluated by the low anterior resection syndrome (LARS) questionnaire. It consists of five single-choice questions and yields a total score ranging from 0 to 42. Defecation function is categorized into three levels: no LARS (0-20 points), minor LARS (21-29 points), and major LARS (30-42 points). The primary endpoint was the LARS score 12 months after surgery. Secondary endpoints included LARS scores from 1 to 11 months and during long-term follow-up(>12 months). The final follow-up was completed in July 2022. All randomized patients were included in the intention-to-treat set (ITTS). The full analysis set (FAS) was defined as ITTS patients with valid outcome data. All primary statistical analyses were performed in the FAS, and results were further compared in the per-protocol set (PPS) based on the actual treatment received.Results:A total of 323 patients underwent eligibility assessment, of whom 71 did not meet the inclusion criteria and 52 declined to participate. Ultimately, 200 patients were randomized. Median age was 64 years and 85 were women. The SEA and EEA groups comprised 102 and 98 patients, respectively. A total of 181 patients (90.5%) were included in the FAS, and 170 (85.0%) were included in the PPS. Among these, the 12-month LARS score was evaluated in 178 patients (98.3%) in the FAS and in 167 (98.2%) in the PPS. Median LARS score at 1–12 months were significantly lower in the SEA group in both the FAS dataset [12 months:8 (interquartile range [IQR], 0–22) vs. 14 (IQR, 8–29); Z=2.687, P=0.007] and the PPS dataset [12 months: 8 (IQR, 0–22) vs. 14 (IQR, 6–29); Z=2.543, P=0.011]. During long-term follow-up, the median LARS score was also significantly lower in the SEA group in the FAS dataset [2 (IQR, 0–4) vs. 11 (IQR, 2–23); Z=2.968, P=0.003] and the PPS dataset [2 (IQR, 0–14) vs. 11 (2, 27); Z=2.687, P=0.007]. Conclusion:Compared with the EEA group, bowel function was superior in the SEA group 1 year after surgery and during long-term follow-up.

Background: Developing and validating a modified parameter, the SYS-G angle (the angle between the lower endplate of the C2 and the upper endplate of C7 vertebrae), as a feasible substitute for the C2–C7 Cobb method in assessing cervical sagittal alignment and exploring its reference range through a large-scale retrospective study. Methods: The visibility of the C6, C7 upper, and C7 lower endplates was graded and compared. Baseline data such as height, weight, body mass index (BMI), age, and sex were analyzed for their impact on the visibility of the C7 lower endplate. Values of C2-6 Cobb angle, SYS-G angle, and C2-7 Cobb angle were measured. The intra- and interobserver reliability, differences, and efficacy of evaluation on cervical lordosis of the parameters were compared, and the correlations among the parameters were analyzed. Furthermore, reference ranges for the SYS-G angle were established based on lateral cervical spine x-rays of 825 asymptomatic Chinese adults across different age groups and sexes. Results: The visibility of the C7 lower endplates was significantly reduced compared to the C6 lower and C7 upper endplates.Age, weight, BMI, and male sex were identified as factors negatively influencing the visibility of the C7 lower endplate. Both intraobserver and interobserver reliability demonstrated excellence for all tested parameters. The linear regression model unveiled a stronger association of the SYS-G angle with the C2-7 Cobb angle compared to the C2-6 Cobb angle. Furthermore, the SYS-G angle exhibited excellent efficacy in evaluating cervical lordosis. Age displayed a positive correlation with the SYS-G angle, and across every age bracket from 20 to 69 years, men exhibited a higher mean SYS-G angle compared to women. Conclusions The visibility of the C7 lower endplate diminishes with increasing age, weight, BMI, and male sex. In cases where the C7 lower endplate is unclear, the SYS-G angle emerges as a reliable method for estimating cervical sagittal morphology. Reference ranges for the SYS-G angle were established across various age groups and sexes among asymptomatic Chinese adults, offering a valuable resource to guide therapeutic interventions for cervical spine disorders and deformities.
