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.

AIM:To investigate the appropriate dose of intravenous dexmedetomidine(Dex)for se-dation in minimally invasive breast surgery under regional block.METHODS:A total of 120 patients with multiple breast masses were selected and di-vided into Dex 0.5 μg/kg group(group D1),Dex 0.75 μg/kg group(group D2),Dex 1.0 μg/kg group(group D3)and normal saline group(group C)ac-cording to the random number table method.After intravenous injection of test drugs,minimally inva-sive rotary cutting under retromammary space an-esthesia was performed.The optimal sedation rate during operation,the optimal sedation rate after operation,Ramsay sedation scores were recorded before anesthesia,at the end of intravenous admin-istration,at the retromammary space anesthesia,at the beginning of surgery,5 min after surgery,at the end of surgery,30 min after administration,and 60 min after administration,visual analogue scale(VAS),vital signs(SBP,DBP,HR,SpO2),the inci-dence of moderate and above pain(VAS＞3)and ad-verse reactions were observed.The optimal seda-tion was defined as intraoperative Ramsay score 2-4 points and postoperative Ramsay score 2-3 points.RESULTS:Dex had a dose-dependent seda-tive and analgesic effect.The optimal sedation rate during operation in group D2 and D3 was significant-ly higher than that in group C and D1,and the opti-mal sedation rate after operation in group D2 was the highest.The rate of VAS score greater than 3 points in group D2 and group D3 was significantly lower than that in group C and group D1,and there was no statistical difference between group D2 and group D3.The incidence of dizziness in group D2and group D3 was higher than that in group C and group D1.There was no significant difference in the inci-dence of hypotension,hypertension,severe brady-cardia,hypoxemia and nausea among the groups.CONCLUSION:Preoperative single intravenous ap-plication of 0.75 μg/kg dexmedetomidine has a def-inite sedative and analgesic effect,and the optimal sedation rate during and after operation is high.It is an appropriate dose for sedation assisted by min-imally invasive breast surgery under regional block.

Objective To explore the correlation between serum hypoxia-inducible factor-1α(HIF-1α)levels and cerebral microbleeds(CMBs)and cognitive impairment and to assess the predictive value of HIF-1α for CSVD-related cognitive impairment.Methods A total of 104 patients with CSVD who attended the Department of Neurology,First Affiliated Hospital of Xinxiang Medical University from June 2022 to November 2023 were enrolled.All enrolled patients were subjected to basic statistics,cranial nuclear magnetic resonance examination,cognitive function assessment,and serum HIF-1α test,and the number and location of CMBs were counted.Based on the above data the enrolled patients were grouped.The correlation between HIF-1α and cognitive function and CMBs was studied the influencing factors of CMBs and cognitive impairment were analyzed,and the predictive value of HIF-1α on the occurrence of cognitive impairment was evaluated.Results There were statistically significant differences in HIF-1α levels and cognitive function among different CMBs groups.Serum HIF-1α levels were significantly negatively correlated with overall cognitive function,visuospatial and executive function,attention,and delayed recall,and serum HIF-1α was positively correlated with the number of CMBs.HIF-1α may be a risk factor for CMBs and cognitive impairment associated with CSVD,and serum HIF-1α has potential in predict the cognitive impairment caused by CSVD.Conclusion Serum levels of HIF-1α were associated with the number of CMB and CSVD-related cognitive impairment,and serum levels of HIF-1α may have a predictive value for CSVD-related cognitive impairment.

Objective·To evaluate the relationships between disc-condyle distance and anterior disc displacement,as well as between disc-condyle distance and disc morphology,in patients with temporomandibular disorders(TMD)using magnetic resonance imaging(MRI)of the temporomandibular joint(TMJ).Methods·From September 2023 to March 2024,90 patients(180 TMJs)who visited the TMJ clinic of Department of Stomatology,The Second Affiliated Hospital of Anhui Medical University,with clinical symptoms of TMD and were diagnosed via MRI with either anterior disc displacement or no significant displacement,were included.Clinical data were collected,and MRI images were used to measure the angle of disc displacement,disc-condyle distance,disc length,and thickness.The degree of disc deformation was assessed.The relationships between clinical symptoms and anterior disc displacement,between anterior disc displacement and both disc morphology and disc-condyle distance,and between disc-condyle distance and disc morphology were analyzed.Results·Among the 90 patients,there were 16 males and 74 females,with a mean age of(28.1±14.5)years.Among the 180 TMJs,175 had clinical symptoms and 5 were asymptomatic.There were 40 joints with no displacement,78 with reducible anterior disc displacement,and 62 with irreducible anterior disc displacement.In the joints with irreducible anterior disc displacement,the proportion of those with two or more symptoms was slightly higher at 62.9%,but the difference was not statistically significant compared with the joints with no displacement or reducible anterior disc displacement.MRI assessment revealed that in the joints with irreducible anterior disc displacement,the proportion of disc deformation type Ⅲ or higher was significantly higher compared with the non-displaced joints(P<0.001).The disc length was significantly shorter(P<0.001),and the intermediate zone thickness was significantly greater(P<0.001)compared with the non-displaced joints.The disc displacement angles at centric closure and maximum opening were also significantly larger(P<0.001).The disc-condyle distance was 3.10(2.70,3.70)mm for non-displaced joints,3.40(3.00,4.00)mm for joints with reducible anterior disc displacement,and 6.60(4.78,7.90)mm for joints with irreducible anterior disc displacement,with significant differences(P<0.001).The disc-condyle distance was 3.10(2.80,3.60)mm for type Ⅰ discs,3.70(3.10,4.60)mm for type Ⅱ discs,5.10(4.00,7.30)mm for type Ⅲ discs,and 6.80(4.98,8.20)mm for type Ⅳ/Ⅴ discs,with significant differences(P<0.001).The disc-condyle distance was negatively correlated with disc length(rs=-0.469,P<0.001),positively correlated with intermediate zone thickness(rs=0.319,P<0.001),and positively correlated with disc displacement angle at centric closure(rs=0.626,P<0.001).Conclusion·With increasing severity of disc deformation,intermediate zone thickness,and disc displacement angle at centric closure,as well as decreasing disc length,the disc-condyle distance increases.The disc-condyle distance is an important indicator for MRI assessment of pathological changes in TMD.

Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

Hypereosinophilia（HE）represents a group of clinical syndromes characterized by increased peripheral blood eosinophils.The etiology spectrum in pediatric patients differs significantly from adults，with secondary（reactive）HE being the most common type.In Chinese children，infections（especially parasitic infections）and allergic diseases are the predominant causes，accounting for approximately 40% and 35% of cases，respectively.Other common causes include immune-related diseases（about 15%）and hematologic neoplasms（about 5%）.Due to the physiological，cognitive，and expressive characteristics of children，identifying the underlying causes can be challenging.This review summarizes the major etiologies，clinical features，and recent advances in pediatric HE，aiming to help clinicians better understand and manage this condition.

Objective:To investigate the risk factors for mortality in neonates with necrotizing enterocolitis (NEC).Methods:This retrospective cohort study included patients diagnosed with NEC at stage Ⅱ-Ⅲ (Bell's criteria) and admitted to the Neonatology Department of Guangzhou Women and Children's Medical Center Affiliated to Guangzhou Medical University from January 2017 to December 2022. According to the outcomes, these patients were divided into the mortality and survival groups. Perinatal conditions, clinical manifestations, disease status during hospitalization, and blood routine parameters at different time points after birth were compared between the two groups to analyze the risk factors for mortality of NEC. Statistical analysis was performed using independent-sample t-test, Mann-Whitney U test, Chi-square test (or Fisher's exact test), and multivariate logistic regression analysis. Results:(1) A total of 118 NEC cases were included, with 100 in the survival group and 18 in the mortality group. (2) The gestational age and birth weight were significantly lower in the mortality group than in the survival group [(28.9±4.2) weeks vs. (33.7±3.9) weeks, t=4.78; 940 g (685-1 275 g) vs. 1 830 g (1 352-2 368 g), Z=4.18; both P<0.05]. The incidence of neonatal asphyxia was higher in the mortality group [9/18 vs. 18% (18/100), χ2=7.13, P<0.05]. (3) Compared with the survival group, the mortality group had higher proportions of patients who were at NEC stage Ⅲ, accepted surgery, were treated with vasoactive drugs, had undergone invasive mechanical ventilation, or had metabolic acidosis, hyperlactatemia, shock, or hematochezia [17/18 vs. 24% (24/100), χ2=33.39; 17/18 vs. 31% (31/100), χ2=22.88; 16/18 vs. 22% (22/100), χ2=31.26; 16/18 vs. 39% (39/100), χ2=15.26; 18/18 vs. 28% (28/100), χ2=30.29; 16/18 vs. 20% (20/100), χ2=34.15; 17/18 vs. 21% (21/100), χ2=37.69; 9/18 vs. 82% (82/100), χ2=7.13; all P<0.05]. (4) The proportions of patients who developed late-onset sepsis, hemodynamically- significant patent ductus arteriosus, respiratory distress syndrome, or pulmonary hemorrhage were significantly higher in the mortality group than in the survival group [15/18 vs. 33% (33/100), χ2=16.01; 9/18 vs. 21% (21/100), χ2=5.32; 15/18 vs. 39% (39/100), χ2=12.08; 7/18 vs. 7% (7/100), χ2=11.94; all P<0.05]. (5) Within 24 h of birth, the levels of red blood cells and platelets were lower in the mortality group than in the survival group [4.1×1012/L (3.8×10 12/L-4.6×10 12/L) vs. 4.6×10 12/L (4.0×10 12/L-4.9×10 12/L), Z=2.04; (199.9±68.6)×10 9/L vs. (239.8±72.6)×10 9/L, t=2.16; both P<0.05]; at 6-8 d after birth, the levels of red blood cells, hemoglobin (Hb) and hematocrit (HCT) were lower in the mortality group than in the survival group [(3.2±0.5)×10 12/L vs. (3.9±0.8)×10 12/L, t=3.30; (111.2±19.2) vs. (138.1±28.3) g/L, t=3.51; (33.0±5.4)% vs. (40.9±8.1)%, t=3.61; all P<0.05]; at the diagnosis of NEC, red blood cell count, Hb level, HCT, and platelet count were lower in the mortality group than in the survival group [(3.3±1.0)×10 12/L vs. (3.8±0.8)×10 12/L, t=2.47; (102.8±28.8) vs. (124.4±26.3) g/L, t=3.59; 31.0% (25.9%-38.4%) vs. 37.2% (31.5%-43.7%), Z=2.62; 87.0×10 9/L (50.2×10 9/L-157.0×10 9/L) vs. 228.0×10 9/L (130.0×10 9/L-414.7×10 9/L), Z=3.78; all P<0.05], while mean platelet volume (MPV), platelet distribution width, and the differences in hemoglobin (ΔHb) and hematocrit (ΔHCT) between the first 24 h after birth and 6-8 d after birth were significantly higher in the mortality group than in the survival group [13.1 fl (11.4-13.6 fl) vs. 11.6 fl (10.7-12.4 fl), Z=3.26; 19.6% (13.9%-25.2%) vs. 14.8% (12.0%-18.6%), Z=2.76; 35.5 g/L (28.3-57.3 g/L) vs. 27.0 g/L (8.0-42.5 g/L), Z=2.20;11.5% (9.4%-16.3%) vs. 6.3% (2.2%-11.2%), Z=2.85; all P<0.05]. (6) Late-onset sepsis ( OR=5.568, 95% CI: 1.201-25.816), hyperlactatemia ( OR=6.702, 95% CI: 1.193-37.651), shock ( OR=10.616, 95% CI: 1.157-97.406) and MPV elevation at the diagnosis of NEC ( OR=2.769, 95% CI: 1.468-5.223) were independent risk factors, while gestational age ( OR=0.836, 95% CI: 0.708-0.986), and HCT at 6-8 d after birth ( OR=0.848, 95% CI: 0.759-0.947) were protecting fctors for death in NEC. Conclusions:Preterm infants with smaller gestational age are more prone to mortality of NEC. Early identification and management of late-onset sepsis, shock, and hyperlactatemia may reduce the risk of mortality in NEC.

Objective:To evaluate the impact of donor characteristics on the prognosis of myelodysplastic syndrome (MDS) patients undergoing haplo-identical transplantation (HIDT) .Methods:A retrospective analysis of 203 MDS patients who received HIDT was conducted to evaluate how donor factors influenced transplant outcomes.Results:In MDS patients undergoing haploidentical transplantation, donors over 50 years were associated with higher EBV reactivation (2-year cumulative incidence 42.9% vs 22.0% for <50 years old; P=0.010). Female donors were linked to increased severe chronic GVHD compared with male donors (2-year incidence 11.9% vs 4.0% ; P=0.017). Additionally, 2-year overall survival (OS) was slightly lower with female donors than male donors (56.6% vs 69.7% ), but the difference was not statistically significant ( P=0.073). Donor-recipient blood type did not affect post-transplant OS or cumulative relapse rates. Donor-recipient kinship analysis revealed that child donors, compared to haploidentical sibling or parent donors, had lower rates of grade Ⅱ–Ⅳ acute GVHD (27.2% vs 45.7% vs 53.5%, P=0.007) and 2-year EBV reactivation (13.9% vs 29.3% vs 38.9%, P=0.001). For donors under 20 years, donor gender did not significantly affect 2-year OS ( P=0.913), relapse-free survival ( P=0.716), or 100-day incidence of grade Ⅱ–Ⅳ acute GVHD ( P=0.359) . Conclusion:For MDS patients undergoing HIDT, donors over 50 should be avoided. Male and child donors are preferred, while donor gender does not significantly affect outcomes if the donor is under 20 years old.

Objective:To investigates the efficacy and safety of allogeneic hematopoietic stem cell transplantation(allo-HSCT)in treating older patients(≥60 years old)with hematologic malignancies.Methods:We conducted a retrospective study involving 67 patients aged 60 years and above, diagnosed with malignant hematological diseases, who received allo-HSCT at the Clinical Research Centrer for Haematologic Diseases of the First Affiliated Hospital of Soochow University between June 2015 and March 2023.We collected pre-transplant data, including the patients' age, gender, pre-transplantation disease risk stratification, disease status, and the haematopoietic cell transplantation comorbidity index(HCT-CI). We retrospectively analyzed clinical data regarding treatment-related toxicity, infections, acute and chronic graft-versus-host disease(a/cGVHD), as well as recurrent and non-recurrent deaths, to estimate the overall survival(OS)rate and event-free survival (EFS)rate.Results:Sixty-seven patients were included in the study, comprising 55 males(82.1%)and 12 females(17.9%), with a median age of 63(61, 65) years .The cohort consisted of 42 cases of acute myeloid leukaemia, 22 cases of myelodysplastic syndromes, and 3 cases of acute lymphoblastic leukaemia.The Kaplan-Meier analysis showed that the 1-year OS and EFS rates were 62.9% and 59.2%, respectively, while the 2-year OS and EFS rates were 55.3% and 51.8%, respectively.The cumulative incidence of 1-year non-relapse mortality and relapse was 25.4% and 21.2%, respectively.A total of 13 patients developed grade Ⅱ-Ⅳ aGVHD, with a 1-year cumulative incidence of 22.0%, and 7 patients developed cGVHD requiring treatment.When stratified by age group, the OS rate was higher in patients aged 60~64 years compared to those aged ≥65 years; however, this difference was not statistically significant(Log-rank χ2=0.99, P=0.317). In contrast, when stratified by disease load, the OS rate was significantly higher in the complete remission(CR)group than in the non-CR group, with a statistically significant difference(Log-rank χ2=15.04, P<0.001). When stratified by donor type, the OS rate was higher in the human leukocyte antigens (HLA) allogeneic group compared to the haploinsufficiency group; however, the difference was not statistically significant(Log-rank χ2=2.71, P=0.100). Twenty-seven patients died at an average of 125 days (range 3-1 054 days) after HSCT.The causes of death included leukemia recurrence in 9 cases (33.3%), infection in 8 cases (29.6%), GVHD in 5 cases (18.5%), poor implantation in 3 cases (11.1%), multi-organ failure in 1 case (3.7%), and cerebrovascular accident in 1 case (3.7%). The results of multifactorial analysis indicated that a pre-transplant tumor load greater than 5% was an independent risk factor for OS after transplantation ( HR=4.59, 95% CI: 2.01-10.42, P<0.001)as well as for disease recurrence ( OR=13.11, 95% CI: 1.96-87.87, P=0.008). Additionally, the occurrence of infection was identified as an independent risk factor for non-recurrent death after transplantation( OR=3.95, 95% CI: 1.13 to 13.71, P=0.031). Conclusions:For patients aged 60 years or older with hematologic malignancies, HSCT can serve as a viable treatment option, particularly for those with refractory recurrence and high cytogenetic risk, as it has the potential to significantly enhance prognosis and increase both EFS and OS rates.
