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.

Patients with Takayasu arteritis combined with aortic valve disease often have a poor prognosis following surgical valve replacement, frequently encountering complications such as perivalvular leakage, valve detachment, and anastomotic aneurysm. This article presents a high-risk case wherein severe aortic valve insufficiency associated with Takayasu arteritis was successfully managed through transcatheter aortic valve implantation via the transapical approach. The patient had satisfactory valve function with no complications observed during the six-month postoperative follow-up. This case provides a minimally invasive and feasible alternative for the clinical management of such high-risk patients.

OBJECTIVE To evaluate the efficacy and safety of apatinib combined with PD-1/PD-L1 inhibitors in the treatment of malignant solid tumors. METHODS Randomized controlled trials （RCTs） on apatinib combined with PD-1/PD-L1 inhibitors （combination group） versus monotherapy （apatinib or PD-1/PD-L1）combined with （or） chemotherapy/other treatments （control group） in the treatment of malignant solid tumors were collected from PubMed， Web of Science， Embase， Cochrane Library， CNKI， VIP， Wanfang Data and China Biomedical Literature Database. The search time limit was from the establishment of the databases to May 2025. After literature screening， data extraction and literature quality evaluation， meta-analysis was performed using RevMan 5.3 and Stata 14.0. RESULTS A total of 28 RCTs involving 2 974 patients were included. The objective response rate [RR＝1.639， 95%CI（1.452，1.851）， P＜0.000 01]， disease control rate [RR＝1.284， 95%CI（1.178，1.399）， P＜0.000 01] and CD3+， CD4+， CD4+/CD8+ as well as the incidence of ADR such as hypertension， fatigue， proteinuria， thrombocytopenia were significantly higher in the combination group than control group （P＜0.05 or P＜0.000 01）. The progressive disease rate [RR＝ 0.497， 95%CI（0.437， 0.566）， P＜0.000 01] and serum tumor + marker levels and CD8 were significantly lower in the combination group than control group （P＜0.05 or P＜0.000 01）. Subgroup analysis results of different types of tumors showed that the objective response rate and disease control rate were significantly higher in the combination group than control group （P＜0.05）. The results of sensitivity analysis showed that the stability of this study was good. The results of publication bias analysis showed that there was a high possibility of publication bias in this study. CONCLUSIONS Apatinib combined with PD-1/ PD-L1 inhibitors has a significant efficacy in the treatment of different types of tumors， but attention should be paid to the occurrence of hypertension， fatigue， proteinuria and thrombocytopenia.

Objective To study a method for determining the cumulative dose of low-energy neutrons ( < 100 keV) independently based on a CR-39 detector. Methods According to the theory of track etching kinetics, the differences in the tracks formed by low-energy neutrons or fast neutrons in a BN + CR-39 detector under broad-spectrum neutron irradiation were analyzed. A method was proposed to identify the tracks produced by low-energy neutrons under specific etching conditions while avoiding interference from fast neutron tracks. Results Experimental results demonstrated that the BN + CR-39 detector using TASTRAK PADC CR-39 track-detecting plastic could independently detect the tracks of low-energy neutrons when etched in a 6.25 mol/L NaOH solution for 1 h. The track density showed a good linear relationship with the ambient dose equivalent of low-energy neutrons, and the calibration coefficient was 0.0366 μSv·tr⁻¹·cm². Conclusion The BN + CR-39 detector proposed in this study demonstrated high sensitivity to low-energy neutrons. The track identification method can be used for effective and independent determination of the cumulative dose equivalent of low-energy neutrons.

OBJECTIVE To optimize the water extraction technology for Kaixin granules. METHODS UPLC-MS/MS method was established for the simultaneous determination of ginsenoside Rg1， ginsenoside Re， ginsenoside Rb1， tenuifolin， polygalaxanthone Ⅲ and 3， 6′-disinapoyl-sucrose. An orthogonal test was designed with extraction times， extraction duration， and the volume of added water as factors. Using the contents of the aforementioned six indicator components and the extract yield as evaluation indexes， analytic hierarchy process-entropy weight method was employed to determine the combined weights of each indicator. Subsequently， process optimization and validation were conducted by integrating grey relational analysis （GRA） and back propagation （BP） neural network. RESULTS The water extraction technology optimized by the orthogonal test and GRA was 10- fold water for the first decoction and 8-fold water for the subsequent two， extracting 3 times，extracting for 1 h each time； the average comprehensive score of the validation experiment was 91.10 （RSD＝0.31%， n＝3）. The water extraction technology optimized by BP neural network was extracting 3 times with 10-fold water added each time， extracting for 1.5 h each time； the average comprehensive score of the validation experiment was 95.89 （RSD＝0.73%， n＝3）. Considering practical production requirements， the optimal water extraction technology was extraction performed three times， with 10-fold water for the first decoction and 8-fold water for the subsequent two extractions， with an extraction time of 1 h each. CONCLUSIONS The optimized water extraction technology for Kaixin granules is stable and feasible.
