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 investigate the dosimetric differences of different types of multileaf collima-tors(MLCs)on the planning target volume(PTV)and organs at risk(OARs)in volumetric modulated arc therapy(VMAT)for cervical cancer.Methods Twenty postoperative patients with cervical cancer receiving radiotherapy in this hospital from May 2023 to January 2024 were selected as the study subjects.For each pa-tient,two kinds of VMAT plans(MLCi2-MLC and AgilityTM-MLC)after cervical cancer operation were de-signed.The dosimetric parameters of the planning target volume(PTV),exposure dose by organs at risk(OAR),y passing rate and monitor units(MU)were compared between the two plans.Results Compared with MLci2-MLC,prescription dose(V45),conformity index(CI)and homogeneity index(HI)in AgilityTM-MLC were better,and the differences were statistically significant(P＜0.05),Compared with MLCi2-MLC,bladder V30,V40,average dose(Dmean),rectal V10,V20,V30,left femoral head V10,Dmean and small intestine V10,V30,Dmean and Dmax were lower,bladder V45,rectal V45,right femoral head V20 were higher,and the differences were statistically significant(P＜0.05).Compared with MLCi2-MLC,the y passing rate in AgilityTM-MLC was lower[(98.31±0.64)％vs.(99.73±0.37)％],and the difference was statistically significant(P＜0.05);while MU had no statistical difference between AgilityTM-MLC and MLCi2-MLC(996.74±65.46 vs.996.80±49.77,P＞0.05).Conclusion AgilityTM-MLC demonstrates better PTV conformity and homogenei-ty,as well as good protection on OARs in both high and low dose regions.

Objective:To investigate drug resistance gene in Mycoplasma pneumoniae(MP) and the distribution of 13 respiratory pathogens in bronchoalveolar lavage fluid(BALF) of children with Mycoplasma pneumoniae pneumonia(MPP).Methods:A total of 100 BALF of children with MPP in Peking University Third Hospital and Peking University First Hospital from January 2018 to January 2019 were collected.Fluorogenic quantitative PCR was used to detect nucleic acid and it′s drug resistance gene of MP and multiple PCR method was adopted to detect influenza A virus, influenza A virus-H 1N 1, influenza A virus-H 3N 2, influenza B, human parainfluenza virus, adenovirus, human bocavirus, human rhinovirus, Chlamydia pneumoniae, human metapneumovirus, MP, human coronavirus, and respi-ratory syncytial virus gene, and the results were compared by using Chi square test. Results:In 100 BALF samples, MP and drug resistance gene were detected by fluorogenic quantitative PCR.Totally, 83 cases (83.00%) were MP positive and 78 cases (93.98%) were drug resistant.All of them had the point mutations A2063G in V region of 23S rRNA domain.A total of 13 kinds of respiratory pathogens were detected by multiplex PCR method, and 89 cases (89.00%) were positive.Totally, 79 cases (79.00%) were MP positive, of which 74 cases (74.00%) detected only MP, and 5 cases (5.00%) detected MP combined with other pathogens.Other pathogens were detected in 10 cases (10.00%). The virus detection rate of 0-4 years old group was higher than that of >4-6 years old group ( P=0.042) and >6 years old group ( P=0.002), and the differences were statistically significant. Conclusions:MP can be detected in most BALF samples of MPP children, the drug resistance phenomenon is serious, and the main point mutation is A2063G.There were other respiratory pathogens and 2 or 3 pathogens were detected in a small number of BALF samples.

Objective To investigate the efficacy of entecavir (ETV) versus tenofovir disoproxil fumarate (TDF) and the treatment measures for poor response in previously untreated chronic hepatitis B (CHB) patients with high viral load. Methods A total of 165 CHB patients who received antiviral therapy and met the inclusion criteria in Department of Infectious Diseases, The First Affiliated Hospital of Guangxi Medical University, from June 2016 to July 2021 were enrolled. The patients enrolled had a baseline HBV DNA level of > 6lg copies/ml and were previously untreated CHB patients who had used ETV or TDF for 48 weeks, and quantitative real-time PCR was used to measure HBV DNA. Virologic response rate was calculated after 48 weeks of treatment; a logistic regression analysis was used to investigate the influencing factors for the response of HBV DNA < 500 copies/mL and HBV DNA < 100 copies /mL at 48 weeks; a stratified analysis was performed to compare the virologic response rate of HBV DNA < 500 copies /ml and HBV DNA < 100 copies/ml after 48 weeks between the patients with different ages, sexes, baseline HBV DNA levels, baseline alanine aminotransferase (ALT) levels, types of first-line medication, and HBeAg statuses. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups, and the binary logistic regression model was used for multivariate analysis. Results After 48 weeks of treatment, 85.5% (141/165) of the patients achieved an HBV DNA load of < 500 copies/mL, and 66.1% (109/165) of the patients achieved an HBV DNA load of < 100 copies /mL, with no significant difference in treatment outcome between the ETV group and the TDF group. The multivariate logistic regression analysis showed that sex( OR =2.793, 95% CI : 1.197-6.517), baseline HBV DNA( OR =0.369, 95% CI : 0.142-0.959), baseline ALT( OR =4.556, 95% CI : 1.770-11.732), and baseline HBeAg( OR =0.120, 95% CI : 0.033-0.429) were influencing factors for complete virologic response(all P < 0.05). For the patients with normal ALT (≤40 U/L) at baseline, 75.6% (34/45) achieved an HBV DNA load of < 500 copies/mL after 48 weeks of treatment, and 53.3% (24/45) achieved an HBV DNA load of < 100 copies/mL, with no significant difference in treatment outcome between the ETV group and the TDF group. For the patients with abnormal ALT (> 40 U/L) at baseline, 89.2% (107/120) achieved an HBV DNA load of < 500 copies/mL after 48 weeks of treatment, and the proportion of such patients in the TDF group was significantly higher than that in the ETV group (96.1% vs 84.1%, χ 2 =4.386, P =0.036); 70.8% (85/120) achieved an HBV DNA load of < 100 copies/mL, the proportion of such patients was no significant difference between the TDF group and the ETV group (78.4% vs 65.2%). The response of HBV DNA < 100 copies/ml of the normal baseline ALT group and the abnormal baseline ALT group, there were no significant differences between the patients aged≤30 years and aged > 30 years (77.8% vs 47.2%, 85.2% vs 66.7%). For the patients who did not achieve complete virologic response (HBV DNA ≥100 copies/mL) after 48 weeks of treatment, 87.9% (29/33) achieved complete virologic response after the original treatment regimen was prolonged for 48 weeks, and 100% (9/9) of the patients achieved complete virologic response after switching to or adding the first-line nucleos(t)ide analogues (NUCs) without cross-resistance sites with the original regimen for another 48 weeks. Conclusion The patients aged > 30 years should receive antiviral therapy as early as possible, regardless of viral load and ALT level, especially those with a family history of liver cirrhosis or hepatocellular carcinoma; the patients aged ≤30 years who have a normal ALT level and a high viral load should consider initiating antiviral therapy after providing informed consent. For the patients with poor response after 48 weeks of treatment, first-line NUCs without cross-resistance sites with the original regimen should be switched to or added in time.

Objective:To retrospectively analyze the serological, virological, biochemical, liver histological status and clinical outcomes in HBeAg-negative chronic hepatitis B (CHB) patients with low HBV viral load, and to explore the necessity of antiviral therapy for these patients.Methods:A total of 99 HBeAg-negative CHB patients with HBV DNA level < 4 lg copies/ml who performed liver biopsy at the baseline were enrolled from the follow-up cohort. Among them, 23 cases received the second liver biopsy during follow-up. The relationships among the degree of inflammation and fibrosis of liver tissues, the status of HBsAg and HBcAg, age, gender, family history, HBV DNA load, serological markers and other indicators were analyzed. The pathological differences between two liver biopsy examinations were compared. The effect of nucleos(t)ide analogues (NAs) treatment on patient’s clinical outcomes were analyzed. For multivariate analysis, a binary logistic regression model was performed. Log-rank test was used to compare the cumulative incidence of hepatocellular carcinoma (HCC) in NAs-treated and non-NA streated patients.Results:Baseline liver histology status showed that 58.6% (58/99) patients had obvious liver tissue damage in their baseline liver tissue pathology (G≥2 and /or S≥2). Univariate logistic regression analysis showed that a liver cirrhosis (LC) family history, a HBsAg-positive family history, baseline alanine aminotransferase and aspartate aminotransferase levels were positively correlated factors for liver tissue damage. Multivariate logistic regression analysis showed that a LC family history was the main risk factor for liver tissue damage. Twenty-three cases had received a second liver biopsy after an interval of 4.5 years. In 10 untreated cases, the second liver biopsy results showed the rate of obvious liver tissue damage (G≥2 and/ or S≥2) increased from 50.0% to 90.0%. In the other 13 cases who received NAs treatment, the second liver biopsy showed improvement in liver histology, and the rate of obvious liver tissue damage decreased from 61.5% to 46.2%. The 5-year HCC cumulative incidence in non-NAs-treated patients was significantly higher than that of in NAs-treated patients (17.7% vs. 3.8%, P = 0.046). Conclusion:For most HBeAg-negative CHB patients with low viral load, liver tissue pathology result suggests that it meets the indications for antiviral therapy, especially in patients with a LC familial history. Without antiviral therapy, liver tissue damage for these patients will progressively worse with the high incidence of HCC. Therefore, it is suggested that antiviral therapy should be started as soon as possible for the HBeAg-negative CHB patients with low viral load regardless of the alanine aminotransferase level, especially in patients over 30 years-old with a LC or HCC family history.

Objective: To describe the status of non-steroidal anti-inflammatory drugs (NSAIDs) use in areas with a high incidence of upper gastrointestinal cancer in China. Methods: This study was based on the National Key Research and Development Program of "National Precision Medicine Cohort of Esophageal Cancer" and "Study on Identification and Prevention of High-risk Populations of Gastrointestinal Malignancies (Esophageal cancer, Gastric cancer and Colorectal cancer)" . From January 2017 to August 2018, 212 villages or communities with a high incidence of esophageal cancer or gastric cancer were selected from 12 regions in 6 provinces. A total of 35 910 residents aged between 40 and 69 years old who met the inclusion criteria and signed the informed consent were investigated and enrolled in this study. The use of NSAIDs, demographic characteristics, health-related habits, height, weight, and blood pressure were collected by the questionnaire and physical examination. The status of main NSAIDs (aspirin, acetaminophen and ibuprofen) use with the difference varying in genders, age groups and regions were analyzed by using χ² test and Cochran-Armitage trend analysis method. Results: Of 35 910 subjects, the mean age was (54.6±7.1) years old and males accounted for 43.42% (15 591). The overall prevalence of NSAIDs intake was 4.56% (1 638), but it significantly varied in different provinces (P<0.001). The overall prevalence of NSAIDs intake was 4.87% (1 750) in females, which was significantly higher than that in males 4.24% (1 524) (P<0.001). The prevalence of NSAIDs intake increased with age (P for trend <0.001). As the frequency of NSAIDs intake increased, the incidence of gastrointestinal symptoms, gastrointestinal ulcers and black stools increased (P for trend <0.05 for all). Conclusion The use of NSAIDs is prevalent in some areas with a high incidence of upper gastrointestinal cancer in China. The increased use of NSAIDs may lead to more adverse effects related to the gastrointestinal tract.

Objective: To explore the influence of cluster nursing intervention on inadequate drainage in vacuum sealing drainage (VSD) for inpatients in burn unit. Methods: From October to December 2016, 60 patients, aged (43.6±2.8) years admitted to our department, receiving VSD treatment and conforming to the inclusion criteria, were included in the routine nursing group, and among the patients, 37 cases were male and 23 cases were female. From May to July 2017, 58 patients, aged (44.2±3.2) years admitted to our department, receiving VSD treatment and conforming to the inclusion criteria, were included in the cluster nursing group, and among the patients, 36 cases were male and 22 cases were female. The patients′ medical records were retrospectively analyzed. After VSD treatment, patients in routine nursing group received routine nursing, and patients in cluster nursing group received cluster nursing. A cluster intervention group was formed and headed by a chief surgeon. The cluster nursing plan was formulated and implemented strictly from the following six aspects of material preparation, negative pressure value control and negative pressure mode setting, drainage tube nursing, semi-permeable membrane reinforcement, standardizing changing process and timing of drainage capsule, and health education. During VSD treatment, the incidence of inadequate drainage, reasons of inadequate drainage and the occurrences, occurrences of inadequate drainage of wounds in different types and sites, and satisfaction of patients in two groups were observed and calculated. The patient satisfaction items included procedure of drainage capsule replacement, the method of tube fixation, the content and form of health education. Data were processed with independent sample t test and chi-square test. Results: (1) During VSD treatment, the incidence of inadequate drainage of patients in routine nursing group was 43.33% (130/300), which was significantly higher than 17.24% (50/290) in cluster nursing group (χ²=43.350, P<0.01). (2) During VSD treatment, the incidences of inadequate drainage caused by blockage of drainage tube due to scabbing of drainage, low negative pressure, air leakage of semi-permeable membrane, improper changing process of drainage capsule, shedding, compression, reversal of drainage tube of patients in cluster nursing group were 7.93% (23/290), 4.48% (13/290), 1.72% (5/290), 1.03% (3/290), and 2.07% (6/290), respectively, significantly lower than 16.67% (50/300), 11.67% (35/300), 4.33% (13/300), 4.00% (12/300), and 6.67% (20/300) in routine nursing group (χ²=10.379, 22.951, 4.832, 7.840, 7.399, P<0.05 or P<0.01). (3) During VSD treatment, the incidences of inadequate drainage of burn wounds, trauma wounds, pressure ulcer, venous ulcer in lower limbs, and diabetic foot of patients in cluster nursing group were significantly lower than those in routine nursing group (χ²=17.835, 6.809, 9.478, 4.939, 8.631, P<0.05 or P<0.01). During VSD treatment, the incidences of inadequate drainage of wounds in different types of patients in the same group were close (χ²=0.434, 0.057, P>0.05). (4) During VSD treatment, the incidences of inadequate drainage of wounds in limbs, trunk, buttocks, and sacrococcyx of patients in cluster nursing group were significantly lower than those in routine nursing group (χ²=31.892, 9.588, 4.939, 4.549, P<0.05 or P<0.01). During VSD treatment, the incidences of inadequate drainage of wounds in different wound sites of patients in the same group were close (χ²=0.071, 0.069, P>0.05). (5) The satisfaction scores in changing process of drainage capsule, method of tube fixation, content and form of health education of patients in cluster nursing group after VSD treatment were significantly higher than those in routine nursing group (t=5.166, 4.471, 7.958, 8.975, P<0.01). Conclusions Cluster nursing intervention on patients receiving VSD treatment could reduce the incidences of inadequate drainage of wounds in different types and sites caused by various reasons. It also can improve patient satisfaction.
