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.

This study aims to innovate a homogeneous outpatient service management system across multiple hospital campuses to enhance service quality.Based on the practical experience of a tertiary general hospital in Guangdong Province and in accordance with the"Interim Regulations on Outpatient Quality Management in Healthcare Institutions,"we constructed a"6+1"homogeneous outpatient service management system.This system includes:① a multi-stakeholder co-governance outpa-tient management system,②a vertical and cross-hierarchical management network,③ a democratic-centralized clinical coordina-tion strategy,④ a guidance-encouragement performance evaluation standard,⑤a collaborative dynamic supervision mechanism,⑥a spiral retrospective evaluation and improvement method,and ⑦ an integrated outpatient diagnosis and treatment system.Af-ter over two years of implementation,the hospital's outpatient volume has grown by an average of over 15％annually,patient waiting time after appointment has been reduced to 20 minutes,and patient satisfaction in the tertiary public hospital performance evaluation achieved full marks.The electronic medical record system functionality reached Level 6,significantly improving healthcare service efficiency and quality while enhancing homogeneous management across campuses.

OBJECTIVE To analyze the ethanol extracts,total phenols,total flavonoids contents and HPLC fingerprints of typi-cal propolis samples from 6 foreign countries and 5 domestic regions,optimize the extraction process and evaluate the antioxidant activi-ty,so as to provide data support for improving the quality control system of propolis.METHODS The optimization of the propolis ex-traction process utilized flavonoid content as an indicator.Three flavonoid detection methods-namely,the aluminum trichloride meth-od,aluminum nitrate method,and polyamide method-were compared.The content of ethanol extract,total phenol content,and the scavenging ability of DPPH free radicals for each sample were determined.Further analysis was conducted using HPLC fingerprint pro-filing.RESULTS The propolis extract with the highest flavonoid content was obtained using 80%ethanol as the extraction solvent,operating at 50℃,with a stirring time of 3 h,ultrasonic power of 180 W,and ultrasonic time of 15 min.The aluminum trichloride method was proved to be the most effective for determining total flavonoids in propolis.While the ethanol extract,total flavonoids,and total phenols of propolis from Xinjiang,China were relatively low,their antioxidant activity exhibited superiority.HPLC analysis re-vealed,Brazilian red propolis lacked of chrysin,galangin,caffeic acid phenethyl ester and Brazilian green propolis lacked ferulic acid,apigenin,p-coumaric acid,chrysin,and pinocembrin.In contrast,the content of these four compounds in other samples varied,with the antioxidant capacity of the extracts not precisely corresponding to the compound content.CONCLUSION Propolis exhibits a complex chemical composition with significant variations among varieties.Key quality control indexes must be comprehensively consid-ered,encompassing physicochemical characteristics and biological activity.Establishing a multi-angle assessment system with a mate-rial basis-functional linkage is essential.This approach facilitates the realization of high quality and cost-effectiveness,thereby promo-ting the healthy development of the industry.

Objective:Based on the autoregressive integrated moving average (ARIMA) model, back propagation neutral network (BPNN), and ARIMA-BPNN model, select the optimal model suitable for predicting the incidence trend of hepatitis C in Taiyuan City according to the characteristics of the data.Methods:The data of reported cases of hepatitis C in Taiyuan from 2008 to 2021 were selected, and the seasonal trend decomposition chart was used to analyze the seasonal characteristics of the monthly incidence rate of hepatitis C in Taiyuan during the period, and the ARIMA model, BPNN model, and ARIMA-BPNN model were established to predict. The performance of the model was measured using four indicators: mean absolute error ( MAE), mean squared error ( MSE), root mean square error ( RMSE), and mean absolute percentage error ( MAPE). Results:A total of 20 025 cases of hepatitis C were reported, and the overall incidence trend was stable. The BPNN model performed well on MSE, MAE, and RMSE indicators, the ARIMA-BPNN model performed well on MAPE indicators, and the ARIMA model performed relatively averagely. Conclusions:The ARIMA-BPNN model is a better model for predicting the trend of hepatitis C in Taiyuan City, with a higher predictive performance than a single model. It has significant prospects in predicting the trend of infectious diseases.

The liver regenerative capacity is crucial for patients with end-stage liver disease following partial hepatectomy (PHx). The specific bacteria and mechanisms regulating liver regeneration post-PHx remain unclear. This study demonstrated dynamic changes in the abundance of Parabacteroides distasonis (P. distasonis) post-PHx, correlating with hepatocyte proliferation. Treatment with live P. distasonis significantly promoted hepatocyte proliferation and liver regeneration after PHx. Targeted metabolomics revealed a significant positive correlation between P. distasonis and β-hydroxybutyric acid (BHB), as well as hyodeoxycholic acid and 3-hydroxyphenylacetic acid in the gut after PHx. Notably, treatment with BHB, but not hyodeoxycholic acid or 3-hydroxyphenylacetic acid, significantly promoted hepatocyte proliferation and liver regeneration in mice after PHx. Moreover, STAT3 inhibitor Stattic attenuated the promotive effects of BHB on cell proliferation and liver regeneration both in vitro and in vivo. Mechanistically, P. distasonis upregulated the expression of fatty acid oxidation-related proteins, and increased BHB levels in the liver, and then BHB activated the STAT3 signaling pathway to promote liver regeneration. This study, for the first time, identifies the involvement of P. distasonis and its associated metabolite BHB in promoting liver regeneration after PHx, providing new insights for considering P. distasonis and BHB as potential strategies for promoting hepatic regeneration.

Although a single nucleotide polymorphism for N-acetyltransferase 10 (NAT10) has been identified in patients with early-onset stroke, the role of NAT10 in ischemic injury and the related underlying mechanisms remains elusive. Here, we provide evidence that NAT10, the only known RNA N4-acetylcytidine (ac4C) modification "writer", is increased in the damaged cortex of patients with acute ischemic stroke and the peri-infarct cortex of mice subjected to photothrombotic (PT) stroke. Pharmacological inhibition of NAT10 with remodelin on Days 3-7 post-stroke or astrocytic depletion of NAT10 via targeted virus attenuates ischemia-induced infarction and improves functional recovery in PT mice. Mechanistically, NAT10 enhances ac4C acetylation of the inflammatory cytokine tissue inhibitor of metalloproteinase 1 (Timp1) mRNA transcript, which increases TIMP1 expression and results in the accumulation of microtubule-associated protein 1 light chain 3 (LC3) and progression of astrocyte autophagy. These findings demonstrate that NAT10 regulates astrocyte autophagy by targeting Timp1 ac4C after stroke. This study highlights the critical role of ac4C in the regulation of astrocyte autophagy and proposes a promising strategy to improve post-stroke outcomes via NAT10 inhibition.

A 42-year-old male patient developed mild allergic symptoms after the use of cisatracurium besylate in laparoscopic left renal tumor resection,which was relieved by symptomatic treatment.When the drug was added again intraoperatively,the patient's blood pressure decreased sharply from 120/71 mmHg to 50/30 mmHg,and the airway resistance increased from 16 cmH2O to 38 cmH2O,and the patient developed typical signs of anaphylactic shock.After immediate intravenous injection of epinephrine,calcium chloride and other drugs,the patient's blood pressure rose to 95/57 mmHg,airway resistance decreased to 20 cmH2O,and vital signs tended to be stable.The Naranjo's Assessment Scale was used to evaluate and analyze the correlation of suspected drugs.The score was 9 points,indicating that the association between anaphylactic shock and cisatracurium besylate in this patient was judged to be"definitely related".This article suggests that cisatracurium besylate carries an allergic risk and should be used with caution,and the monitoring of vital signs and allergic reactions should be strengthened for early identification and timely treatment to ensure the safety of patients during the perioperative period.

Objective To investigate the therapeutic effects of varying treatment durations of recombinant human brain natriuretic peptide(rhBNP)on heart failure following percutaneous coronary intervention(PCI)in patients with acute ST-segment elevation myocardial infarction(STEMI).Methods A total of 196 STEMI patients with heart failure(HF)following emergency percutaneous coronary intervention(PCI)were enrolled and randomly assigned to one of four groups:control group(n=53),short-course rhBNP group(n=47),medium-course rhBNP group(n=50),and long-course rhBNP group(n=46).The rates of cardiovascular mortality and HF-related rehospitalization were evaluated at 30 days and 6 months post-treatment.Serum levels of N-terminal pro-B-type natriuretic peptide(NT-proBNP),matrix metalloproteinase-9(MMP-9),tissue inhibitor of matrix metalloproteinase-1(TIMP-1),left ventricular end-diastolic diameter(LVEDD),and left ventricular ejection fraction(LVEF)were measured at 24 hours,3 days,1 week,30 days,and 6 months after HF treatment initiation.Results Compared with the control group,both the short-and medium-term rhBNP groups showed a significant reduction in cardiovascular mortality and HF-related rehospitalization rates in the long-term rhBNP group at 30 days and 6 months(P<0.05).Additionally,the medium-term rhBNP group exhibited lower HF-related rehospitalization rates than both the control and short-term rhBNP groups(P<0.05).Serum levels of NT-proBNP,MMP-9,and LVEDD significantly decreased in the short-term rhBNP group within 24 hours compared to the control group(P<0.05),while TIMP and LVEF levels increased(P<0.05).In comparison with the short-term rhBNP group,the medium-term rhBNP group demonstrated sustained reductions in NT-proBNP,MMP-9,and LVEDD levels at 72 hours,1 week,30 days,and 6 months(P<0.05),accompanied by increases in TIMP and LVEF(P<0.05).Furthermore,the long-term rhBNP group showed greater improvements than the medium-term group,with significantly lower NT-proBNP,MMP-9,and LVEDD levels and higher TIMP and LVEF values at 1 week,30 days,and 6 months(P<0.05).In terms of the adverse reactions,the incidence of hypotension in the control group,short course rhBNP group,medium course rhBNP group and long course rhBNP group increased successively(P<0.05).Conclusion The clinical efficacy of rhBNP in STEMI patients with HF following PCI gradually improved as the treatment duration increased,but the incidence of hypotension also rose accordingly.

BACKGROUND:Postoperative results with Meek skin grafting in some patients with extremely severe burns have not been satisfactory,with problems of delayed healing or skin graft failure. There have been fewer studies on the treatment of patients with failed Meek skin grafting due to insufficient skin source. This study aimed to explore a treatment method for such patients. OBJECTIVE:To observe the curative effect of stamp-shaped skin allograft in the treatment of severe burns after Meek skin graft failure. METHODS:Twenty-three patients with extremely severe burns who were admitted at Department of Burns and Skin Surgery,the First Affiliated Hospital of the Air Force Medical University from August 2013 to August 2023 with poor healing after Meek skin grafting were enrolled and divided into allogeneic skin treatment group and dressing change group according to different treatment methods. There were 10 cases in the allograft group and 13 cases in the dressing change group. Preoperative hemoglobin,platelet count,albumin count,white blood cell count,neutrophil count,procalcitonin count,and positive rate of microbial culture before secondary Meek skin grafting were compared between two groups. Survival rate of skin grafts before and after the second operation were compared. The number of operations,incidence of sepsis,and wound scars at 3 months and 6 months after operation were retrospectively analyzed. RESULTS AND CONCLUSION:The preoperative hemoglobin,platelet count and albumin count in the allogeneic skin treatment group were significantly higher than those in the dressing change group (Z=-3.172,P=0.002;Z=-3.010,P=0.003;Z=-2.761,P=0.006). There was no significant difference in the preoperative white blood cell count and neutrophil count between the two groups before secondary Meek skin grafting (Z=1.148,P=0.251;Z=0.373,P=0.709),but the serum procalcitonin count in the allogeneic skin treatment group prior to the second operation was significantly lower than that in the dressing change group (Z=2.955,P=0.002). Burn patients in the dressing change group exhibited a higher microbial culture rate than those in the allogeneic skin treatment group (x2=6.303,P=0.029). The survival rate of skin grafts before the second operation in the allogeneic skin treatment group[(74.8±13.3)％]was significantly higher than that in the dressing change group[(58.4±14.2)％;t=2.85,P=0.01). The survival rate of skin grafts after the second stage operation in the allogeneic skin treatment group[(84.0±11.5)％]was significantly higher than that in the dressing change group[(67.6±20.7)％;t=2.24,P=0.03). The frequency of postoperative surgery in the allogeneic skin treatment group was less than that in the dressing change group (Z=2.27,P=0.02). The incidence of sepsis in the dressing change group was significantly higher than that in the allogeneic skin treatment group (x2=5.490,P=0.03). There was no significant difference in the Vancouver Scar Scale scores of the scars between the two groups at 3 and 6 months after operation (t=0.96,1.138,P>0.05). To conclude,stamp-shaped skin allograft has good curative effect in the treatment of wounds with poor healing of skin after Meek micro-transplantation. The utilization rate of skin in the later stage is significantly increased,which reduces the probability of wound infection and solves the problem of insufficient skin source.
