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.

The theory of constitution in traditional Chinese medicine （TCM） has emerged as a new discipline in recent years. Constitution plays a vital role in the onset，progression，transformation，and prognosis of diseases. At present，some clinical scholars have adopted a novel diagnostic and treatment model of "constitution differentiation-disease identification-syndrome differentiation"，in which constitution is regarded as a core element throughout the diagnostic and therapeutic process. Constitution is closely associated with etiology，onset，pathogenesis，syndrome differentiation，and treatment. Against this background，the construction of animal models based on constitution holds far-reaching significance for advancing clinical research. This paper focuses on the construction and evaluation of rodent models with Qi-deficiency constitution，aiming to explore how to further induce Qi-deficiency syndromes and related disease states on the basis of Qi-deficiency constitution models，thereby developing an integrated animal model that embodies the trinity of "constitution-disease-syndrome". The establishment of this model not only provides a solid experimental foundation for the development of new therapies and drugs in TCM targeting specific constitutions，diseases，and syndromes，but also greatly promotes the modernization and scientific advancement of TCM theory. By comprehensively applying multidisciplinary technologies and methods，the study evaluates the model's validity，reliability，and practicality，with the aim of opening new avenues for future research in TCM and promoting the development of the field.

Objective To investigate the effects of ischemia time and storage periods on RNA quality in fresh-frozen breast cancer(BC)and esophageal cancer(EC)tissue samples in order to establish evidence-based protocols for biobank sample management.Methods The tumor(T)and paired normal(N)tissue samples from 6 cases of BC and 6 cases of EC were collected and cryopreserved in Biobank,Shantou Central Hospital.Mirror paraffin-embedded tissues were simultaneously prepared into sections for morphological analysis.The samples were divided into two groups of<15 min and 15-30 min according to ischemia time,and RNA quality was analyzed at 4 storage periods of 8-10 months(T1),14-16 months(T2),26-28 months(T3)and 38-40 months(T4).Results In 96 analyzed samples,93.8%(90/96)exhibited high quality(RIN≥6),with 89.6%(43/48)in BC and 97.9%(47/48)in EC.Significant differences in RIN were observed between BC group and EC group(8.050 vs.8.600,P=0.009).In EC group,RIN value was significantly negatively correlated with RNA yield(P<0.001).Moreover,RIN values of tumor-normal pairs exhibited markedly significant differences(7.550 vs.9.000,P<0.001).In contrast,no significant difference was detected in BC group(8.200 vs.7.700,P=0.348).Statistical analysis showed that RIN value was positively correlated with 28S/18S(P<0.001),but had no correlation with tumor content(P=0.676)and necrotic content(P=0.055).Neither ischemia time(<15 min vs.15-30 min:8.200 vs.8.300,P=0.932)nor storage periods(T1-T4:8.400,7.700,8.450,8.600,P=0.163)compromised RNA quality.Conclusion Organ origin and tissue type could influence RNA quality of fresh-frozen tissue samples.However,limited ischemia time(≤30 min)and long-term storage period(38-40 months)do not adversely affect RNA quality in fresh-frozen breast cancer and esophageal cancer tissue samples.

BACKGROUND:Previous studies have found that for postmenopausal osteoporosis patients,the Bushen Jianpi Formula can help regulate serum osteoclast-and osteoblast-related factors and intestinal flora levels,improve clinical symptoms of patients and further improve efficacy.OBJECTIVE:To investigate the effect of Bushen Jianpi Formula on bone metabolism and bone microarchitecture in ovariectomized rats.METHODS:Twenty-four female SD rats were randomly divided into four groups by random number table method:sham operation group(n=6)was subjected to periovarian fat removal,and bilateral ovariectomy was performed in model group(n=6),alendronate group(n=6),and Bushen Jianpi Formula group(n=6).Five days after modeling,the Bushen Jianpi Formula group was given Bushen Jianpi Formula by intragastric administration(once a day).The alendronate sodium group was given alendronate by intragastric administration(once a week).The sham operation group and model group were given an equal volume of normal saline by intragastric administration(once a day)for 12 consecutive weeks.After intragastric administration,serum levels of procollagen Ⅰ N-terminal peptide,β-isomerized C-terminal telopeptide of type Ⅰ collagen degradation product,and tumor necrosis factor α were detected.The distal femur microstructure was detected by Micro-CT.The femoral tissue morphology was observed by hematoxylin-eosin staining.The expression of type Ⅰ collagen and tumor necrosis factorα in the femur was detected by immunohistochemical staining.RESULTS AND CONCLUSION:(1)The serum ELISA test showed that compared with the sham operation group,the level of procollagen Ⅰ N-terminal peptide in the model group decreased(P＜0.05),and the levels of degradation products of β-isomerized C-terminal telopeptide of type Ⅰ collagen and tumor necrosis factor α increased(P＜0.05).Compared with the model group,the levels of the procollagen Ⅰ N-terminal peptide in the Bushen Jianpi Formula group and the alendronate sodium group increased(P＜0.05),and the levels of β-isomerized C-terminal telopeptide of type Ⅰ collagen degradation products and tumor necrosis factor α decreased(P＜0.05).(2)Micro-CT three-dimensional reconstruction showed that compared with the sham operation group,the number of bone trabeculae in the model group was significantly reduced,the continuity was worsened,and the gaps were increased.Both alendronate sodium and Bushen Jianpi Formula had a positive improvement effect on this phenomenon.(3)Hematoxylin-eosin staining showed that compared with the sham operation group,the number of bone trabeculae in the model group was reduced and the shape became thinner,and the network structure was destroyed.Compared with the model group,the number of bone trabeculae in the Bushen Jianpi Formula group and the alendronate sodium group increased,the shape became thicker,and the reticular structure was restored.(4)Immunohistochemical staining showed that compared with the sham operation group,the expression of type Ⅰ collagen was reduced and tumor necrosis factor α expression was increased in the model group.Compared with the model group,the expression of type Ⅰ collagen increased and the expression of tumor necrosis factor α decreased in the Bushen Jianpi Formula group and the alendronate sodium group.The results show that the Bushen Jianpi Formula can effectively improve bone metabolism and bone microstructure in ovariectomized rats.

Objective:To observe the clinical effect of Cangfu Daotan Decoction combined with ethinylestradiol and cyproterone acetate,metformin in patients with spleen deficiency phlegm-dampness type polycystic ovary syndrome(PCOS)accompanied by insulin resistance.Methods:80 patients with PCOS accompanied by insulin resistance who were admitted to our hospital from June 2023 to June 2024 were included.The patients were divided into control group(treated with ethinylestradiol and cyproterone acetate,metformin)and study group(treated with modified Cangfu Daotan Decoction combine with ethinylestradiol and cyproterone acetate,metformin)by the random number table method,with 40 cases in each group.The total clinical effective rate,TCM syndrome score,sex hormone levels[prolactin(PRL),estradiol(E2),follicle-stimulating hormone(FSH),testosterone(T),and luteinizing hormone(LH)],insulin resistance indicators[fasting insulin(FINS),fasting blood glucose(FBG),homeostatic model assessment of insulin resistance(HOMA-IR)],and endometrial receptivity[pulsatile index(PI),resistance index(RI),endometrial thickness(ET),ovulation rate]and the occurrence of adverse reactions were compared between the two groups.Results:Compared with the control group after treatment,the total clinical effective rate,PRL,E2,FSH level,ET and the ovulation ratein the study group were higher,while the main symptoms,secondary symptoms,total score,T,LH levels,FBG,FINS levels,HOMA-IR,PI and RI were lower(P＜0.05).There was no difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion:Cangfu Daotan Decoction combined with ethinylestradiol and cyproterone acetate,metformin in patients with spleen deficiency phlegm-dampness type PCOS accompanied by insulin resistance,can improve the clinical symptoms,increase the total clinical effective rate,it may be related to the regulation of insulin resistance,sex hormone levels,and endometrial receptivity,it is safe and reliable.

This study was aimed at identifying the pathogenic bacteria responsible for the death of a young tiger at the Fujian Meihua Mountain South China Tiger Breeding Research Institute.Tissue samples from the lungs,liver,and intestines of the deceased tiger were collected,and the bacteria were cultured inasterile environment.The bacterial strains were characterized according to their morphological and molecular biological properties,including assessment of virulence genes and antibiotic resistance genes,mouse lethality tests,and antibiotic susceptibility evaluations.A predominant bacterial strain isolated from the liver of the deceased tiger was identified as enterotoxigenic Escherichia coli(ETEC)strain Tiger22513F.Phylogenetic analysis of the 16S rRNA gene revealed that the Tiger22513F strain exhibited close genetic similarity to the reference strain ETEC(MF919609.1),with 99.9%nucleotide similarity,and resided on the same evolutionary branch.The Tiger22513F strain contained 11 antibiotic resistance genes(tetA,sul1,sul3,cmlA,floR,blaTEM,blaSHV,blaCMY-2,qnrA,qnrS,and qnrD)along with five virulence genes(VT1,fyuA,tsh,iucD,and ST).Mouse lethality tests indicated significant pathogenicity toward mice,affecting primarily the lungs,liver,and intestines.Antibiotic susceptibility testing demonstrated that this strain exhibited resistance to various classes of beta-lactam antibiotics,as well as quinolones and aminoglycosides.This investigation successfully isolated a multi-drug resistant enterotoxigenic Escherichia coli strain with pronounced pathogenicity from the liver of a deceased tiger;thus providing valuable scientific insights for clinical diagnosis,as well as prevention and control measures,against ETEC infections in South China tigers.
