Objective To explore the perioperative safety and prognostic factors of sequential hepatectomy after conversion therapy using vascular interventional therapy(including transarterial chemoembolization and hepatic arterial infusion chemotherapy)combined with tyrosine kinase inhibitors(TKI)and programmed death-1(PD-1)inhibitors in patients with initially unresectable hepatocellular carcinoma.Methods The clinical data of 106 eligible HCC patients treated in Tumor Hospital Affiliated to Guangxi Medical University from Nov.2019 to Apr.2024 were retrospectively analyzed.The perioperative parameters and postoperative pathological outcomes were described in detail,and factors influencing prognosis were analyzed.Results The median operative time for hepatectomy after conversion therapy was 240 min,with a median blood loss of 200 mL.Intraoperative blood transfusion was required in 24(22.6％)patients.Postoperative adverse reactions occurred in 49.1％(52/106)of patients,with liver failure being the most common adverse reactions(23 patients,21.7％).One(0.9％)patient died during the perioperative period,while the remaining 105 patients were followed up for a median duration of 14.7 months,during which 49(46.2％)patients experienced recurrence.Among them,39(36.8％)cases experienced early recurrence(within 1 year),and 33(31.1％)cases had intrahepatic recurrence.Thirteen(12.3％)patients died during follow-up.The median recurrence-free survival(RFS)was 15.7 months,with 1-year and 2-year RFS rates being 56.9％and 40.3％,respectively.The median overall survival(OS)was not reached,with 1-year and 2-year OS rates being 94.2％and 85.3％,respectively.Multivariate Cox regression analysis demonstrated that achieving complete pathological response(hazard ratio[HR]=0.410,95％confidence interval[CI]0.172-0.980,P=0.045),presence of microvascular invasion(HR=2.423,95％CI 1.269-4.625,P=0.007),satellite nodules(HR=1.916,95％CI 1.014-3.620,P=0.045),and multiple tumors(HR=1.818,95％CI 1.012-3.241,P=0.046)were independent factors associated with postoperative recurrence.Conclusion For patients with initially unresectable hepatocellular carcinoma,vascular interventional therapy combined with TKI and PD-1 inhibitors followed by sequential hepatectomy may be a feasible treatment strategy,with manageable adverse reactions and promising efficacy.

Objective:To establish UPLC characteristic spectrum of Hujiao standard decoction and the determination method for the content of piperine.Methods:15 batches of freeze-dried powder of Hujiao standard decoction were prepared according to the traditional decocting method. The range of paste yield was determined, and the UPLC characteristic spectrum of the standard decoction was established. High-resolution mass spectrometry and control products were used to identify common peaks. Based on the common peak area, the weights of each peak were compared using entropy weight method, and correlation analysis and similarity evaluation were conducted using clustering analysis and grey correlation method; a method for determining the content of piperine in Hujiao decoction pieces and freeze-dried powder of standard decoction was simultaneously established, and the transfer rate was calculated.Results:The extraction rate of 15 batches of freeze-dried powder of Hujiao standard decoction ranged from 10.4% to 16.8%, with an average of 14.0%. The content of piperine ranged from 12.2 to 30.0 mg/g, with an average of 18.5 mg/g, and the transfer rate ranged from 4.0% to 7.8%, with an average of 5.8%. Six common peaks were identified in the established characteristic spectrum and identified by high-resolution mass spectrometry and control products respectively. Peak 1 was N-trans-feruloyltyramine, peak 3 was piperine and the similarity was 0.959-1.000. Clustering analysis and grey correlation analysis showed that there was little difference between quality of Piperis Fructus and origins.Conclusion:In this study, the characteristic spectrum and content determination method of freeze-dried powder of Hujiao standard decoction are established, which can provide references for quality detection and control of Hujiao standard decoction or its derivative products.

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.

Objective To understand the current status of fear of missing out(FoMO)social interaction in adole-scent patients with severe accidental trauma,and to explore its potential categorical characteristics,and analyze the influencing factors of different categories.Methods A convenience sampling method was employed to select 301 adolescent patients with severe accidental trauma admitted to the surgical and trauma ICU of a tertiary hospital in Chengdu City from January to December 2024.Data were collected using a general information survey,the Fear of Missing Out Scale,the Adolescent Learning Stress Scale,and the Self-Perceived Burden Scale.Latent profile analysis and multiple logistic regression analysis were used to determine different profiles and their influencing factors.Results A total of 245 adolescent patients with severe accidental trauma were ultimately included,with a Fear of Missing Out Scale score of(21.55±8.17),being categorized into 4 potential profiles of"independent type"(28.16％),"normal type"(19.59％),"social dependence type"(22.04％),and"information deficiency type"(30.20％).The results of multiple logistic regression analysis showed that literacy,per capita monthly family income,level of academic stress,level of self-awareness of medical staff care,being an only child,level of self-perceived burden,and length of hospitalization were the factors influencing the potential profiles of FoMO social interaction in adolescent patients with unintentional trauma(all P＜0.05).Conclusion There is group heterogeneity in FoMO social interaction among adolescent patients with severe accidental trauma.Medical staff should develop targeted intervention measures based on the classification characteristics of different profiles of missing anxiety in adolescent accidental trauma patients to alleviate their levels of FoMO social interaction.

Objective:To explore the interactive transfer effects between ICU transferred patients' and their primary caregivers' transfer readiness and relocation stress using the Actor-Partner Interdependence Model (APIM) .Methods:A convenience sampling method was used to select 304 pairs of ICU patients and their primary caregivers, who were transferred from the ICU between January and July 2024 at West China Hospital of Sichuan University. A general information questionnaire, ICU patients Transfer Readiness Scale, Relocation Stress Syndrome Scale-Short Form, Caregiver Preparedness Scale, and Family Relocate Stress Syndrome Scale were used to collect data. The APIM was applied to analyze the relationship between ICU patients' and caregivers' transfer readiness and relocation stress.Results:The transfer readiness scores of 304 pairs of ICU patients and their primary caregivers were (65.22±10.04) and (14.57±4.84) , respectively, and the relocation stress scores were (25.06±5.34) and (50.35±7.38) , respectively. APIM analysis showed that the transfer readiness of ICU patients negatively predicted their own relocation stress ( P<0.05) , and the transfer readiness of primary caregivers negatively predicted their own relocation stress ( P<0.05) . The ICU patients' transfer readiness negatively predicted the primary caregivers' relocation stress ( P<0.05) , while the transfer readiness of primary caregivers did not significantly predict the ICU patients' relocation stress ( P>0.05) . Conclusions:ICU patients' relocation stress is influenced by their own transfer readiness, while primary caregivers' relocation stress is jointly influenced by both their own and the patients' transfer readiness. This suggests that healthcare providers should pay attention to the transmission of relocation stress between ICU patients and their families and actively explore family-based intervention strategies.
