Objective:This study aimed to evaluate the global research landscape, identify trends, and determine hotspots concerning hepatoma recurrence post-liver transplantation.Methods:We conducted a bibliometric analysis usinga systematic search was conducted in the Web of Science Core Collection database from Jan. 1992 to Oct. 2023 to identify relevant articles on hepatoma recurrence after liver transplantation. Articles were selected based on inclusion and exclusion criteria and analyzed for publication trends by country/region, journal, author, institution, citation, and keyword. Visualization tools such as Citespace, VOSviewer, and Bibliometric.com were utilized for statistical analysis, identification of emerging trends, and clustering of keyword co-occurrence.Results:Out of 4,936 articles retrieved, 1,189 were included in the final analysis. There was a notable increase in publications on hepatoma recurrence following liver transplantation from 1992 to 2021, peaking in 2021 both globally (n=103) and nationally (n=32). China has the largest number of publications in this field (n=308), maintaining significant collaboration with the United States, South Korea, Japan, Canada. 'Liver Transplantation’ journal had the highest number of publications (n=113). Zhejiang University was the leading institution (n=74), with Academician Zheng Shusen being the most prolific scholar (n=76 publications). Citation emergence detection found that Italian scholar Mazzaferro's Predicting survival after liver transplantation in patients with hepatocellular carcinoma beyond the Milan criteria: a retrospective, exploratory analysis published on The Lancet Oncology in 2009 had the highest burst strength (36.98). Five bursting keywords were identified: alpha fetoprotein, model, validation, sorafenib, and risk. Cluster analysis of keyword co-occurrence revealed five primary research themes: the medication for hepatocellular carcinoma recurrence after liver transplantation, recipient selection criteria, prognostic factors, development and validation of recurrence prediction model, and local treatments for hepatocellular carcinoma.Conclusions:The study underscores rapid advancements in the research on hepatocellular carcinoma recurrence post-liver transplantation over the past three decades, with significant contributions from Chinese scholars, particularly from Zhejiang University and Academician Zheng Shusen. The evolving research hotspots have shifted from transplantation experiences and recipient selection criteria to early post-transplant recurrence risk prediction and therapeutic strategy development.

Objective To evaluate the cost-effectiveness of roxadustat and darbepoetin alfa on treating renal anemia in dialysis-dependent chronic kidney disease(DD-CKD)patients,thus providing health economics reference for treatment of renal anemia.Methods A Markov model simulating the development and treatment of anemia in DD-CKD patients in a lifetime horizon(20 years)was constructed.Total costs of roxadustat and darbepoetin alfa injection were estimated from the perspective of Chinese healthcare system,with health outcomes converted into quality-adjusted life year(QALY).The incremental cost-effectiveness ratio(ICER)was used to describe the results.The willingness-to-pay(WTP)threshold was set at 257 094 yuan,which was three times China's gross domestic product(GDP)per capita in 2023.Sensitivity analyses were performed to test the uncertainties of the results.Results The total treatment costs of roxadustat and darbepoetin alfa injection were 111 902.41 yuan and 52 927.92 yuan respectively,corresponding to QALY values of 4.76 and 4.74 life-years.The incremental cost-effectiveness(ICER)was 2 654 912.45 yuan/QALY,which exceeded 3 times GDP per capita.Therefore,compared with darbepoetin alfa injection,roxadustat has no cost-effectiveness for patients with DD-CKD.Conclusion In the context of current economic development in China,darbepoetin alfa injection is more cost-effective than roxadustatin for treating anemia in DD-CKD patients.

Objective:To analyze assessment value of the hemodynamics of posterior cerebral artery(PCA)detected by transcranial color-coded Doppler(TCCD)ultrasound for occurring cerebral infarction in patients with fetal-type posterior cerebral artery(FTP).Methods:A total of 300 patients with suspected cerebrovascular disease admitted to the Department of Neurology of The Second Hospital of Harbin City from January,2020 to December 31,2023 were retrospectively selected.In these patients,7 cases with cerebral hemorrhage(without complication of cerebral infarction)did not be included.According to the clinical manifestations and the results of imaging examination,293 patients were divided into transient ischemic attack(TIA)group(176 cases)and acute ischemic stroke(AIS)group(117 cases).The differences in FTP detection between TCCD examination and magnetic resonance angiography(MRA)were compared.The differences in PCA hemodynamics among TIA,anterior circulation infarction,posterior circulation infarction and lacunar infarction were compared.The proportions of patients with TIA,anterior circulation infarction,posterior circulation infarction and lacunar infarction combined with FTP were also compared,and the PCA hemodynamics of patients with posterior circulation infarction of bilateral cFTP,unilateral cFTP,bilateral pFTP,unilateral pFTP and nFTP were compared.The proportions of patients with transient ischemic attack(TIA)who occurring AIS at bilateral cFTP,unilateral cFTP,bilateral pFTP,unilateral pFTP and nFTP in short term were compared.The receiver operating characteristic(ROC)curve and area under curve(AUC)were used to assess the predictive value of abnormal PCA hemodynamics of TIA patients,who combined with and/or without FTP,occurred AIS in short term.Results:MRA revealed that a total of 89 patients combined with FTP in 293 patients,of which 14 cases were bilateral cFTP(accounting for 15.73%),and 25 cases were unilateral cFTP(accounting for 28.09%),and 8 cases were bilateral pFTP(accounting for 8.99%),and 42 cases were unilateral pFTP(accounting for 4 7.19%).According to TCCD testing,it was found that a total of 89 cases combined with FTP in 293 patients,of which 16 cases were bilateral cFTP(accounting for 17.98%),and 23 cases were unilateral cFTP(accounting for 25.84%),and 8 cases were bilateral pFTP(accounting for 8.99%),and 42 cases were unilateral pFTP(accounting for 47.19%).There was favorable consistency between TCCD and MRA(Kappa=0.899).Under TCCD,the blood flow velocity(Vp)and resistance index(RI)of systolic stage of PCA in patients with posterior circulation infarction were significantly higher than those in patients with TIA,anterior circulation infarction,and lacunar cerebral infarction(F=15.392,9.032,P<0.05),respectively.Patients with posterior circulation infarction were more likely to occur bilateral cFTP.The Vp,Vm and Vd of patients with bilateral cFTP were significantly higher than those of patients with bilateral pFTP,unilateral pFTP and non-FTP(F=14.932,8.884,6.054,P<0.05),respectively.The proportion of occurring AIS in TIA patients with bilateral cFTP was significantly higher than that in TIA patients with unilateral cFTP,bilateral pFTP,unilateral pFTP and nFTP(Z=6.883,7.568,6.253,6.772,P<0.05),and the proportions of occurring AIS in TIA patients with unilateral cFTP,bilateral pFTP and unilateral pFTP were significantly higher than that in TIA patients with nFTP(Z=5.986,6.877,6.856,P<0.05),respectively.A total of 45 cases(accounting for 25.57%)of 176 TIA patients occurred AAIS within 3 months after they discharged.The AUC value of predictive value of Vp for occurring AIS in 45 TIA patients with FTP was 0.818,which was significantly higher than that(AUC=0.589)for occurring AIS in 131 TIA patients with non-FTP.Conclusion:Patients with posterior circulation cerebral infarction are prone to occur PCA hemodynamic abnormalities.In patients with posterior circulation infarction,the PCA blood flow velocity in patients with bilateral cFTP significantly accelerates.PCA hemodynamic ultrasound examination has a certain of predictive value for occurring AIS in short term in TIA patients who combine with FTP.

OBJECTIVE To screen the quality biomarkers of Gnaphalium affine with anti-chronic obstructive pulmonary disease （COPD） effect and determine their contents. METHODS The effective components and targets of “G. affine” with anti- COPD effect were predicted by using network pharmacology as a search criterion. HPLC fingerprints for 10 batches of G. affine were established by using Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition）； common peak identification and similarity evaluation were conducted； cluster analysis （CA）， principal component analysis （PCA）， and orthogonal partial least squares-discriminant analysis （OPLS-DA） were performed to screen differential components as quality maker that affected the quality of G. affine using variable importance projection （VIP）＞1 as the standard. The same HPLC method was adopted to determine the contents of the differential components in 10 batches of samples. RESULTS A total of 10 flavonoids （such as quercetin， luteolin， and chlorogenic acid） and organic acid components， were identified through network pharmacology search， with 91 targets closely related to anti-COPD. A total of 9 common peaks were identified in 10 batches of samples， with similarity greater than 0.90. Among them， the differential components included chlorogenic acid， caffeic acid， 1，3-O- dicaffeoylquinic acid and apigenin 7-O-β-D-glucopyranoside； S3， S4， S6， S7 and S10 were clustered into one category， S2， S5， S8 and S9 clustered into one category， and S1 clustered into one category. The contents of chlorogenic acid， caffeic acid， 1，3-O- dicaffeoylquinic acid， and apigenin 7-O-β-D-glucopyranoside in 10 batches of G. affine ranged 0.070-7.653， 0.010-0.097， 0.001- 0.036， 0.508-6.627 mg/g， respectively. CONCLUSIONS Chlorogenic acid， caffeic acid， 1，3-O-dicaffeoylquinic acid， apigenin 7- O-β-D-glucopyranoside can serve as the potential quality marker for the anti-COPD effect of G. affine， with the highest content of chlorogenic acid in G. affine produced in Ji’an， Jiangxi province， and the highest content of caffeic acid in G. affine produced in Ji’an， Jiangxi province and Sanming， Fujian province. The contents of the last two components are highest in G. affine produced in Chaoshan， Guangdong province.

Objective To explore the effect of chemotherapeutic drugs doxorubicin or cisplatin on lipid metabolism of macrophages and its regulatory mechanism.Methods Macrophage RAW264.7 was treated with doxorubicin or cisplatin,and intracellular lipid level was detected by oil red O and ELISA;RNA sequence screen-ing and Western blot were used to confirm the changes of gene expression after chemotherapeutic drug treatment;The effects of silencing ROBO3 on cellular lipid metabolism were explored,and changes in key target genes of lipid metabolism were detected by Q-PCR and western blot.Results Adriamycin or cisplatin induced disturbances in macrophage cholesterol metabolism and exacerbated macrophage foaminess.Further studies showed that the expression of the axon guidance factor receptor,ROBO3,increased and then decreased during the chemotherapeutic drug-induced macrophage foaming process.Further intervention with ROBO3 exacerbates oxldl-induced cholesterol accumulation and foam formation in macrophages.Mechanistically,ROBO3 deficiency promotes the expression of cholesterol synthesis-related gene DHCR24 and inhibits the expression of cholesterol elimination-related gene ABCG1,resulting in cholesterol accumulation in macrophages.Conclusion This study found that ROBO3 plays an important regulatory role in the disruption of cholesterol metabolism and its foaming process in macrophages induced by chemotherapeutic drugs,which may provide new targets and ideas for the prevention and treatment of chemotherapy-related atherosclerosis.

Methods:From July to December 2021, Yanzhou District of Jining City, Ningyang County of Taian City, and Dongying District of Dongying City were selected as surveillance sites to investigate the population and distribution range of Pomacea spp., live snail samples were collected for morphological and genetic identification, and Pomacea spp. infected with the larva of Angiostrongylus cantonensis was detected by lung test. At the same time, sentinel hospital case surveillance was carried out in Yanzhou District, Jining City, and questionnaire was used to study the local residents' awareness of angiostrongyliasis cantonensis and their personal health behaviors. Results:A total of 312 live snail samples were collected. After morphological identification, they were all Pomacea spp.. After gene sequencing, two populations of Pomacea canaliculata and Pomacea maculata were found. No positive snails infected with Angiostrongylus cantonensis were found. A total of 126 patients with headache as the main neurological symptom were admitted to the sentinel hospital, but there were no monitoring cases that met the inclusion criteria. Among the survey population, 48.38% (134/277) of the respondents had heard of angiostrongyliasis cantonensis, 44.77% (124/277) knew that eating Margarya melanioides might cause angiostrongyliasis cantonensis, and 83.39% (231/277) had no related unhealthy eating behavior. Conclusion:Pomacea spp. is found and reported for the first time in Shandong Province, and there is a risk of population infection with angiostrongyliasis cantonensis.

Objective:To explore health utility value, evaluate health-related quality-of-life(QOL)of pediatric liver transplantation(LT)recipients and examine its influencing factors to provide rationales for related health economic evaluations.Methods:This cross-sectional QOL was conducted through a questionnaire in pediatric LT recipients aged 5-17 years.The interviewees undergoing initial LT from June 2013 to September 2021 were reviewed regularly.Those children and their parents unwilling to participate or failing to understand the contents of questionnaire were excluded.The questionnaire was designed on the basis of Child Health Utility 9D Instrument(CHU9D)and answered online by one of primary caregiver.Chinese score system of CHU9D was employed for converting the responses into health utility values and the influencing factors were analyzed.Univariate analysis was performed by nonparametric tests and multivariate analysis by multiple linear regression model. P<0.05 was deemed as statistically significant. Results:A total of 140 valid questionnaires were obtained.Mean age of pediatric LT recipients was(7.95±2.74)years and mean postoperative time(4.90±2.17)years.Among them, 19 cases had experienced acute rejection and 101(72.1%)cases were living-related LT recipients.CHU9D scale indicated that average health utility value was(0.85±0.14)points.Univariate analysis revealed that age( P=0.008), education level( P<0.001)and primary disease( P=0.010)influenced the postoperative level of QOL.Multivariate analysis indicated that QOL was correlated with education level(behind schedule: 95% CI: -0.146, -0.034, P=0.002; leave of absence: 95% CI: -0.251, -0.068, P=0.001). Conclusions:Health utility of pediatric LT recipients is high with an excellent QOL.Poor QOL is associated with absence from school or dropping out of school.

Objective To provide a reliable and stable animal model for investigating the molecular pathogenesis of radiation-induced liver disease (RILD). Methods Ninety C57BL/6J mice were divided into control, 20 Gy, 25 Gy, 30 Gy and 35 Gy radiation groups. The mice were executed at 4 weeks after radiation and the levels of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase in the liver serum were measured. HE staining was performed on the pathological liver tissues. Masson staining was performed at 36 weeks after radiation. Results Compared with the control group, the fatality rate was higher in the 30 and 35 Gy radiation groups, and the body weight significantly decreased in the 20 and 25 Gy radiation groups. Compared with the control group, alanine aminotransferase significantly increased in mice exposed to 20 Gy, while aspartate aminotransferase and alanine aminotransferase increased in mice exposed to 25 Gy. No significant changes were observed in the livers of the mice in the 20 and 25 Gy radiation groups, but pathological examination showed liver damage induced by both 20 and 25 Gy radiation. Conclusion A stable and reliable mouse model of RILD was constructed for treatment with linear accelerator. The mouse model of RILD constructed for stereotactic body radiation therapy using linear accelerator has significant research implications for the exploration of RILD.
