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.

Cirrhotic portal hypertension is a clinical syndrome caused by persistently elevated portal venous pressure due to liver cirrhosis and can lead to a series of complications， among which esophagogastric variceal bleeding has become one of the most severe complications due to sudden onset and a high mortality rate. Since the release of Expert consensus on diagnosis and treatment of esophagogastric variceal bleeding in cirrhotic portal hypertension （2019 edition）， significant advances have been achieved in this field in China and globally. In order to formulate an expert consensus aligned with the situation of China， Chinese Society of Surgery， Chinese Medical Association organized and compiled Expert Consensus on diagnosis and treatment of esophagogastric variceal bleeding in cirrhotic portal hypertension （2025 edition）. This article elaborates on the key updates in the new edition and explores the major differences between the old and new editions， in order to enhance the understanding of the new edition among clinicians and provide a reference for clinicians in clinical work.

ObjectiveTo investigate the role of DEAD-box helicase 3 X-linked （DDX3X） in immune-mediated liver injury （ILI）， and to clarify its mechanism by regulating endoplasmic reticulum stress （ERS）-dependent apoptotic pathway and its association with the clinical progression of hepatitis B. MethodsMice were given injection of concanavalin A （ConA） via the caudal vein to establish a model of ILI， PBS （control group） and different concentrations of ConA were injected into the tail vein of hepatocyte-specific DDX3X-knockout mice （DDX3X^ΔHep and DDX3X-flox mice （DDX3X^fl/fl）， respectively.. The log-rank survival analysis， measurement of the serum levels of aspartate aminotransferase （AST） and alanine aminotransferase （ALT）， and HE staining of liver tissue were performed to assess liver injury， and qRT-PCR and Western Blot were used to measure the mRNA and protein expression levels of glucose-regulated protein 78 （GRP78）， CCAAT/enhancer-binding protein homologous protein （CHOP）， and DDX3X in liver tissue. Intraperitoneal injection of 4-phenylbutyric acid （4-PBA， 100 mg/kg） was performed to inhibit ERS. Serum samples （n=30） and liver tissue samples （n=6） were collected from healthy controls， chronic hepatitis B （CHB） patients， and hepatitis B virus-associated liver failure （HBV-LF） patients； ELISA was used to measure the serum level of DDX3X， and qRT-PCR/Western Blot was used to analyze the expression of targets in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the control group of mice， the expression of DDX3X in the liver of mice induced by ConA was significantly increased after liver injury （P<0.05）， and hepatocyte-specific DDX3X knockout increased the 72-hour survival rate of mice by 55% （compared with 20% in the DDX3X^fl/fl group）， with significant reductions in the serum levels of ALT and AST （P<0.000 1） and the expression levels of the ERS markers GRP78 and CHOP （P<0.05）. After ERS was inhibited by 4-PBA， there was alleviation of liver injury （with reductions in ALT and AST， P <0.001） and a reduction in DDX3X expression （P<0.01）. The analysis of clinical samples showed that the mRNA and protein expression levels of liver DDX3X in CHB patients and HBV-LF patients were significantly higher than those in healthy controls （all P<0.01）， and there was a significant increase in the serum level of DDX3X in HBV-LF patients （P<0.000 1）. ConclusionDDX3X exacerbates ILI by regulating the ERS-dependent apoptotic pathway （GRP78/CHOP）， and its expression is associated with the progression of hepatitis B. Therefore， it can be used as a potential therapeutic target.

Xuanfuhua Decoction （旋覆花汤） is considered as the theoretical prototype of the method of unbloc-king collaterals with acrid and moistened medicinals. Guided by the theories of "chronic disease entering the collaterals" and "collaterals performing their functions when there is free flow"， YE Gui further developed this approach into a systematic method. The core of this approach lies in dispersing and opening constraint with acrid medicinals， nourishing and harmonizing collaterals with moistened medicinals， eliminating pathogens and unblocking collaterals with insect medicinals. The disease course of idiopathic pulmonary fibrosis （IPF） is prolonged， with a complex of deficiency and excess， and chronic disease entering the collaterals. The core pathogenesis involves lung collaterals obstruction， fluid depletion with blood stasis， and chronic disease entering the collaterals. Treatment can be guided by the method of unblocking collaterals with acrid and moistened medicinals based on Xuanfuhua Decoction， following a strategy of "dispersing and unblocking， moistening and nourishing， penetrating and venting". Specifically， for lung collaterals obstruction， acrid medicinals can be used to disperse lung qi and open bi （痹）. In case of fluid depletion and blood stasis， moistened medicinals for nourishing lung collaterals are suggested to restore vitality. For chronic disease ente-ring collaterals， it is advised to search and eliminate collateral pathogens in order to dissipate masses.

Acute brain injury (ABI) affects up to one-third of patients using mechanical circulatory support (MCS). In venoarterial extracorporeal membrane oxygenation (VA ECMO), ABI incidence (11%–40%) has not improved in two decades. Conversely, improvements in left ventricular assist devices (LVADs) have reduced the incidence of stroke, although it remains a major complication (10%–30%). The failure of MCS to ensure adequate cerebral protection may impair cerebrovascular autoregulation (CVAR) and disrupt microcirculatory function affected by reduced pulsatility, endothelial injury, acute perturbations in partial pressure of arterial carbon dioxide (PaCO2), and cerebral venous congestion. Here, we review evidence demonstrating that these factors alter microcirculatory dynamics and CVAR, thereby contributing to ABI through shared mechanistic pathways. Current methods for assessing CVAR are reviewed, including invasive indices such as the pressure reactivity index (PRx) from intracranial pressure monitoring and noninvasive metrics such as the cerebral oximetry index (COx) from near-infrared spectroscopy or flow-velocity correlations from transcranial Doppler. Each method is limited by feasibility, signal artifacts, and inter-modality variability. Our review identifies three priority areas for cerebral protection in MCS: preservation of pulse pressure, cautious titration of PaCO2, and integration of CVAR-informed blood pressure management. Preliminary evidence suggests that very low pulse pressure, rapid carbon dioxide correction, and persistent microcirculatory impairment are each associated with ABI risk. Future investigations should focus on validating bedside tools to assess CVAR and microcirculatory integrity, and on determining whether physiological targets derived from these measures can improve neurological outcomes in patients using MCS.

Objective: To explore the association between transfusion of different allogeneic blood components and the risk of venous thromboembolism (VTE) in hospitalized patients, to clarify the differences in thrombotic risk among various blood components, and to develop a targeted VTE risk prediction model. Methods: A retrospective cohort study was conducted, enrolling 5 406 hospitalized patients who received allogeneic blood transfusion in our hospital from November 2024 to October 2025. Using 1∶1 nearest neighbor propensity score matching (PSM), 5 402 non-transfused patients were selected as controls. The matching variables included sex, age, VTE risk score, VTE prophylaxis, comorbid tumor, use of antibiotics, and invasive mechanical ventilation, with a caliper of 0.01 and sampling without replacement. Standardized mean difference (SMD) was used to assess matching quality, with SMD<0.1 indicating balanced baseline characteristics. The transfusion group was stratified by the type of blood component transfused. The chi-square test with Bonferroni correction and multivariate logistic regression (including forced adjustment for the unbalanced variables VTE prophylaxis and antibiotic use) were used to analyze risk factors. A prediction model was constructed and validated using the area under the receiver operating characteristic (ROC) curve and the Hosmer-Lemeshow test. The optimal cut-off value was determined by the maximum Youden index. Results: All variables showed SMD<0.1 after matching, indicating good baseline balance. The incidence of VTE was significantly higher in the transfusion group than in the control group (8.7% vs 4.3%, RR=2.02, 95% CI: 1.74-2.35, P<0.001). Significant differences in VTE incidence were observed among different transfusion subgroups, with a thrombotic risk gradient of combined transfusion > plasma > red blood cells ≈ platelets. The incidence of VTE in the combined transfusion subgroup was 11.7%, which was significantly higher than that in the red blood cell subgroup (RR=3.20, 95% CI: 2.41-4.24, P<0.001), plasma subgroup (RR=1.71, 95% CI: 1.24-2.35, P<0.001), and platelet subgroup (RR=6.81, 95% CI: 2.56-18.06, P<0.001). The prediction model showed good discrimination and calibration, with an area under the ROC curve of 0.800. The optimal cut-off value determined by the Youden index was 0.12, corresponding to a sensitivity of 62.3% and a negative predictive value of 91.4%. Conclusion: Allogeneic blood transfusion was an independent risk factor for VTE in hospitalized patients, with significant differences in thrombotic risk among different blood components. The prediction model developed in this study can achieve VTE risk stratification in transfused patients, providing evidence for precise transfusion therapy and patient blood management.

To understand the progress of, summarize experiences from, and analyze problems in the national schistosomiasis elimination programme, this article presented the national schistosomiasis epidemiology and surveillance in the People’s Republic of China in 2025. By the end of 2025, Shanghai Municipality, Zhejiang Province, Fujian Province, Guangdong Province and Guangxi Zhuang Autonomous Region maintained the achievement of schistosomiasis elimination, and 7 provinces of Jiangsu, Sichuan, Yunnan, Hubei, Hunan, Anhui and Jiangxi remained at the criteria of schistosomiasis transmission interruption. In 2025, there were 450 counties (cities, districts), 3 203 townships and 26 029 villages endemic for schistosomiasis in China, with a total population of 73.598 million in endemic villages. Among the 450 endemic counties (cities, districts), 421 (93.56%) achieved the criteria of schistosomiasis elimination and 29 (6.44%) reached the criteria of transmission interruption. In 2025, a total of 3 630 874 residents received immunological tests for schistosomiasis across endemic areas in China, with 31 588 seropositives identified (seroprevalence, 0.87%), and a total of 154 293 individuals received parasitological examinations, with 5 egg-positives detected. A total of 26 688 advanced schistosomiasis cases were recorded in China by the end of 2025. Of 529 683 bovines raised in schistosomiasis-endemic villages in China in 2025, 101 637 bovines received immunological tests for schistosomiasis, with 183 seropositives detected (seroprevalence, 0.18%), and 165 654 bovines received parasitological examinations, with no egg-positives identified. In 2025, Oncomelania hupensis snail survey was performed covering an area of 667 524.82 hm² in China, and 176 378.64 hm² O. hupensis snail habitats were identified, including 123.77 hm² emerging O. hupensis snail habitats and 953.71 hm² re-emerging O. hupensis snail habitats. A total of 19 283 schistosomiasis cases received chemotherapy with praziquantel in China in 2025, and 477 450 person-times and 304 279 herd-times received expanded chemotherapy, respectively. In addition, O. hupensis snail control with chemical treatment covered 116 475.10 hm² snail habitats across China in 2025, with an actual area with chemical control covering 68 510.93 hm² and an area with environmental improvements covering 1 101.84 hm². The national schistosomiasis surveillance results indicated that the mean prevalence of Schistosoma japonicum infections was both 0 among humans and bovines in 2025, and no S. japonicum infection was detected in O. hupensis snails. These data showed that the prevalence of schistosomiasis remained low in China in 2025; however, the area of O. hupensis snail habitats stayed high, with an increase in emerging and reemerging O. hupensis snail habitats. It is recommended to improve the surveillance and forecast mechanism for schistosomiasis and precisely implement the O. hupensis snail control programme in high-risk areas.

Tuberculosis （TB） is a major infectious disease that seriously endangers public health. In traditional Chinese medicine （TCM）， TB is considered to be caused by "exogenous latent tuberculosis pathogens"， and whether the disease occurs depends on the strength of healthy Qi. The disease course is characterized by five features： Hidden latency， pathological accumulation， triggering due to deficiency of healthy Qi， depletion of healthy Qi， and prolonged progression with difficulty in recovery. The latent stage is based on the fundamental pathogenesis of "specific latent pathogens concealed in the lung collaterals and waiting for the appropriate time to manifest"， which exhibits the temporal and spatial characteristics of latent pathogens. During this stage， Mycobacterium tuberculosis remains in a dormant state and maintains a dynamic balance with the host immune system. The triggering and progression stages are characterized by the core pathogenesis of "deficiency of healthy Qi initiating pathogenic factors and excessive pathogenic factors triggering disease". Immune dysfunction may lead to severe pathological damage to the structure of the lung collaterals. The key pathogenesis of the latent-retention stage is "persistent latent pathogens consuming healthy Qi"， which is also the core reason for the difficulty in treating initial TB onset， prolonged disease progression， and recurrent attacks. Based on the theory of latent pathogens， this study establishes a four-stage prevention and treatment system "with pathogenesis as the guiding principle and disease stages as the criteria". The corresponding therapeutic principles include tonifying Qi and nourishing Yin， clearing and transforming latent phlegm， regulating and tonifying the spleen and kidney， strengthening healthy Qi and replenishing the primordial Qi， nourishing Yin and reducing fire， suppressing and eliminating tuberculosis pathogens， tonifying deficiency， restoring primordial Qi， clearing residual pathogens， and eliminating pathogenic factors. Guided by the theory of latent pathogens， this article systematically elucidates the TCM connotation of M. tuberculosis invasion of the lung collaterals and the staged syndrome differentiation and treatment approach， providing theoretical foundations and practical guidance for the prevention and treatment of TB through integrated Chinese and Western medicine and offering new perspectives for the prevention and control of infectious diseases using TCM.

ObjectiveTo investigate the clinical and pathological features of intrahepatic intraductal papillary neoplasm of the bile duct （IPNB）， and to improve the understanding， diagnosis， and treatment of this disease. MethodsA retrospective analysis was performed for four patients who underwent surgical resection in Beijing Chaoyang Hospital， Capital Medical University， from January 2010 to December 2025 and were diagnosed with intrahepatic IPNB based on pathological examination. The clinical， imaging， and pathological features of these patients were summarized， and a literature review was performed for related articles in China and globally. ResultsAmong the four patients， there were three female patients and one male patient， with a median age of 65 years， and clinical manifestations included jaundice， abdominal pain or diarrhea， and asymptomatic findings on physical examination. The main imaging manifestation was bile duct dilatation or solid-cystic space-occupying lesion. Pathological typing revealed one case each of the gastric， intestinal， pancreatobiliary， and oncocytic types， and there was one patient with low-grade intraepithelial neoplasia and three patients with high-grade intraepithelial neoplasia， among whom one patient also had invasive carcinoma. ConclusionIntrahepatic IPNB is a rare precancerous lesion of the liver with diverse clinical， imaging， and pathological manifestations， and radical surgical resection remains the cornerstone of treatment.

ObjectiveTo evaluate the larvicidal effect of ultrasonic waves against Aedes albopictus larvae at various exposure parameters (distance and time), and to preliminarily investigate the effects of different containers (water volume and depth) and ultrasonic devices on the larvicidal efficacy, so as to provide experimental evidence for the application of ultrasound-based mosquito control technology. MethodsUnder controlled laboratory conditions, two commercially available ultrasonic devices [40 kHz/300 W and (50±5) kHz/70 W] were used to systematically examine the effects of exposure distance (20, 40, 60, 80, and 100 cm), exposure duration (1, 3, 6, 15 and 60 min), larval instar(Ⅰ‒Ⅱ and Ⅲ‒Ⅳ）, and container type on the immediate mortality of Aedes albopictus larvae collected from urban areas of Shanghai. Statistical analysis of the mortality rates of larvae among different experimental groups was performed using the chi-square test. ResultsUltrasonic exposure exerted a detectable larvicidal effect against Aedes albopictus larvae of all instars. For early-instar larvae, exposure time significantly affected mortality at all tested distances (20, 40, 60, 80 and 100 cm), with χ² values ranging from 25.57 to 32.74 ( all P<0.001). No significant distance effect was observed in the first and second instar larvae after short-term exposure (1 and 3 min; P>0.05). However, a distance-dependent effect emerged from 6 min onward (P<0.05). During short-term exposure (1 min and 3 min) at close range (20 cm and 40 cm), the immediate mortality of the third and fourth instar larvae was higher than that of the first and second instar larvae. Conversely, during prolonged exposure (15 min and 60 min), the first and second instar larvae exhibited significantly higher mortality than that of the third and fourth instar larvae. These results indicated that larval mortality was jointly influenced by exposure duration and distance. Preliminary experiments indicated that larvicidal efficacy in shallow water was lower than that in deep water. No significant difference in larvicidal effect was observed between the two ultrasonic devices with different frequencies and power outputs. ConclusionUnder laboratory conditions, ultrasound can effectively kill Aedes albopictus larvae, and the larvicidal effect is jointly influenced by larval instar, exposure distance, and aquatic environment. Compact ultrasonic devices show potential for field application in biological mosquito control.
