ObjectiveTo investigate the association between noninvasive liver fibrosis markers and carotid plaque （CP） in patients with lean metabolic dysfunction-associated fatty liver disease （MAFLD）， and to provide a basis for screening high-risk populations. MethodsA total of 957 patients with lean MAFLD who underwent physical examination in Subei People’s Hospital from January 2021 to June 2023 was enrolled as the observation cohort， with the presence or absence of CP as the outcome， and fibrosis-4 （FIB-4） index and nonalcoholic fatty liver disease fibrosis score （NFS） were used to assess liver fibrosis degree. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. The multivariate logistic regression analysis， the restricted cubic spline analysis， the receiver operating characteristic curve， and the mediation effect analysis were used to investigate the association between liver fibrosis degree and CP. ResultsThe prevalence rate of CP was 36.6% in the lean MAFLD population. Compared with the non-CP group（n=607）， the CP group （n=350） had a significantly higher proportion of male patients， a significantly higher proportion of patients with smoking/diabetes/hypertension， and significantly higher levels of age， creatinine， blood urea nitrogen， triglycerides， fasting blood glucose， aspartate aminotransferase， aspartate aminotransferase/alanine aminotransferase ratio， NFS， and FIB-4 index， as well as significantly lower levels of platelet count and albumin （all P<0.05）. The multivariate logistic regression analysis showed that after adjustment for confounding factors， FIB-4 index （odds ratio［OR］=2.979， 95% confidence interval［CI］：2.141 — 4.219， P<0.001） and NFS （OR=1.747， 95%CI： 1.499 — 2.046， P<0.001） were positively correlated with CP. Both FIB-4 index and NFS had a good value in predicting CP. Hypertension had a significant indirect effect on the prevalence rate of CP through its impact on liver fibrosis markers， and its mediating effect accounted for 39.5% — 40.8% of the total effect （P<0.001）. ConclusionIn patients with lean MAFLD， NFS and FIB-4 index are significantly positively correlated with the prevalence rate of CP， and they can be used as potential epidemiological predictive indicators. Liver fibrosis markers may play a mediating role in the association between hypertension and CP. Interventions targeting hypertension and liver fibrosis markers may help to prevent and delay the progression of CP.

ObjectiveTo investigate the association of liver fibrosis scores and inflammation markers with gallstones in patients with metabolic dysfunction-associated fatty liver disease （MAFLD）， as well as the mediating role of liver fibrosis scores in the relationship between inflammation markers and gallstones. MethodsA total of 14 567 patients who received physical examination and were diagnosed with MAFLD in Subei People’s Hospital from January 2014 to June 2023 were enrolled in this study， and according to the results of abdominal color Doppler ultrasound， they were divided into gallstone group with 1 724 patients and non-gallstone group with 12 843 patients. Related clinical data were collected from all patients， including demographic data， medical history， family history， physical examination， Color Doppler ultrasound， and biochemical parameters. The biomarkers associated with metabolic disorders and insulin resistance included triglyceride-glucose index （TyG）， TyG-body mass index （BMI） index， atherogenic index of plasma （AIP）， and non-high-density lipoprotein cholesterol-to-high-density lipoprotein cholesterol ratio （NHHR）； the biomarkers associated with inflammation and nutritional status included neutrophil-to-lymphocyte ratio （NLR）， neutrophil percentage-to-albumin ratio （NPAR）， and monocyte-to-lymphocyte ratio （MLR）； the biomarkers for assessing liver fibrosis degree and liver function included albumin-bilirubin （ALBI） score， NAFLD fibrosis score （NFS）， fibrosis-4 （FIB-4） index， and aspartate aminotransferase-to-platelet ratio index （APRI）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， while the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. Multivariate Logistic regression analysis， restricted cubic spline analysis， and mediating effect analysis were used to assess the association of liver fibrosis markers and inflammation markers with the risk of gallstones. ResultsThe prevalence rate of gallstones was 11.8% among the MAFLD patients. There were significant differences between the gallstone group and the non-gallstone group in sex， age， smoking history， diabetes， hypertension， lymphocytes， platelets， glucose， albumin， serum uric acid， alanine aminotransferase， aspartate aminotransferase， red blood cell， NLR， NPAR， MLR， NFS， FIB-4 index， and ALBI score （all P<0.05）. The multivariate Logistic regression analysis showed that NLR （odds ratio ［OR］=1.091， 95% confidence interval ［CI］： 1.028　—　1.160， P<0.05）， NPAR （OR=1.073， 95%CI： 1.042　—　1.105， P<0.05）， MLR （OR=1.142， 95%CI： 1.057　—　1.232， P<0.05）， NFS （OR=1.239， 95%CI： 1.190　—　1.291， P<0.05）， and FIB-4 index （OR=1.326， 95%CI： 1.241　—　1.417， P<0.05） were influencing factors for the prevalence rate of gallstones. The restricted cubic spline analysis showed a significant non-linear association between NFS/FIB-4 index and the risk of gallstone （non-linear P<0.05）. The mediating effect analysis further showed that the association of NLR， MLR， and NPAR with gallstones was partially mediated by NFS or FIB-4 index， with a mediating effect accounting for 36.79%、28.09%、29.67% and 18.31%、17.70、11.57%， respectively. ConclusionNFS and FIB-4 index have a non-linear association with the prevalence rate of gallstones in MAFLD patients， and they also mediate the association of NLR， NPAR， and MLR with the risk of gallstone.

Objective: To explore the feasibility, precision, and clinical value of a personalized primary repair approach centered on digital design, integrating 3D printing technology with multiple materials such as titanium mesh, polyetheretherketone (PEEK), and titanium plates, for complex craniofacial bone defects involving the skull, mandible, orbit, and zygoma resulting from traffic accidents, providing a reference for primary repair of clinically complex craniofacial bone defects. Methods: One patient who was admitted in September 2021 with multiple comminuted fractures of the right craniomaxillofacial region and large-area bone defects caused by a traffic accident was selected. Digital design was integrated throughout the entire repair process. First, preoperative computed tomography (CT) data were used for 3D reconstruction of the craniomaxillofacial region; then, based on the model, the anatomical contour of the healthy left side was reproduced via mirroring technology for the defects on the right side. A targeted repair plan was designed: 3D-printed PEEK material was used to reconstruct the right orbital floor and zygomaticomaxillary complex, a 0.6-mm-thick titanium mesh was adopted to repair the right skull defect, and a 2.0-mm-thick titanium plate was applied for rigid internal fixation of the mandibular fracture. A one-stage repair surgery was completed simultaneously. In addition, a literature review was conducted on studies related to the repair of complex combined craniomaxillofacial defects. Results: CT examination at 1 week postoperatively showed that the average fitting gap of the implants was 0.3 mm, and the symmetry difference of the facial contour was less than 5 mm. At 3 months postoperatively, the patient’s maximum mouth opening reached 38 mm, the occlusal relationship returned to normal, and the diplopia symptom completely disappeared. During the 6-month postoperative follow-up, no complications such as implant loosening, infection, or displacement occurred; the FACE-Q scale score was 91, indicating a high level of subjective patient satisfaction. The literature review indicated that digital design combined with 3D printing technology can significantly improve the accuracy of complex craniomaxillofacial bone defect reconstruction. PEEK material is suitable for the reconstruction of the orbital floor and zygomaticomaxillary complex. Titanium mesh and plates can ensure the stability of the reconstruction. Multi-materials combined reconstruction represents an important therapeutic strategy for such defects. Conclusion The individualized one-stage repair scheme, centered on digital design and combined with 3D printing technology and multi-materials (titanium mesh, PEEK, and titanium plates), can achieve precise anatomical reduction and simultaneous functional recovery for complex combined craniomaxillofacial bone defects caused by traffic accidents.

ObjectiveTo compare the clinical efficacy of traditional Chinese medicine （TCM） manipulative reduction combined with small splint fixation versus surgical treatment for type A distal radius fracture （DRF） and to explore the factors influencing the choice of treatment. MethodsA multi-center retrospective study was conducted， collecting data from 1237 type A DRF patients treated in 11 hospitals in Jiangsu province from September， 2023 to April， 2025. Among them， 851 patients in the TCM group received manipulative reduction combined with small splint fixation， and 386 patients in the surgical group underwent open reduction and internal fixation. Visual analog scale （VAS） scores for pain and radiographic indicators including palmar tilt， ulnar deviation， and radial height were compared before treatment， 5-7 days after treatment， and 4-6 weeks after treatment. The wrist joint function scores including Dienst and Gartland-Werley scores at 12 weeks after treatment were recorded. Subgroup analysis was conducted for the excellent rate of Dienst and Gartland-Werley scores， stratified by age （＜50， 50-59， 60-69， ≥70 years old） and AO subtypes （A1， A2， A3）. A multivariate logistic regression model was used to identify independent factors influencing treatment choice. ResultsOn 5-7 days after treatment， the surgical group had lower VAS scores than the TCM group， while 4-6 weeks after treatment， the TCM group showed lower VAS scores than the surgical group （P＜0.01）. In terms of radiographic indicators， except for the palmar tilt before treatment being higher in the surgical group than in the TCM group （P＜0.01）， there were no significant differences in palmar tilt， ulnar deviation， and radial height at other timepoints （P＞0.05）. Twelve weeks after treatment， the surgical group had a higher average Gartland-Werley score and the excellent rate than the TCM group （P＜0.01）. Subgroup analysis showed that in patients with A2 type DRF aged 50-59 and 60-69 years old， the excellent rates of Dienst and Gartland-Werley scores in the TCM group were higher than those in the surgical group （P＜0.05）. Multivariate logistic regression analysis revealed that age， palmar tilt， ulnar deviation， and the degree of swelling on the affected side were independent factors influencing the choice of treatment （P＜0.05）. ConclusionBoth TCM manipulative reduction combined with small splint fixation and surgical treatment for type A DRF can achieve good therapeutic effects. TCM manipulative reduction combined with small splint fixation has certain advantages in medium- and long-term pain relief， especially in elderly patients， where wrist joint function recovery is more stable. Age， palmar tilt， ulnar deviation， and swelling degree are the main factors influencing the treatment choice.

Objective To investigate the short- and long-term prognoses and the risk factors affecting “textbook outcome” (TO) after laparoscopic pancreaticoduodenectomy (LPD) for pancreatic ductal adenocarcinoma (PDAC). Methods The clinical and follow-up data of patients diagnosed with PDAC and treated with LPD from January 2019 to December 2022 were retrospectively analyzed. The prognosis was compared between TO and non-TO groups, and univariate and multivariate logistic regression analyses were used to identify independent prognostic factors for TO. Results A total of 284 patients were enrolled in this study, including 185 cases in the TO group and 99 cases in the non-TO group. The 1-, 3- and 5-year overall survival (OS) rates of the TO and non-TO groups with PDAC were 87.3% vs. 85.9%, 52.5% vs. 38.4%, and 18.0% vs. 4.5%, respectively (P=0.020); the recurrence-free survival (RFS) rates were 74.1% vs. 65.7%, 27.1% vs. 21.0%, and 10.0% vs. 0%, respectively (P=0.042). Multivariate logistic regression analysis showed that operation time >360 min (OR=0.561, 95%CI: 0.321-0.979, P=0.042), intraoperative blood loss >400 ml (OR=0.392, 95%CI: 0.175-0.879, P=0.023), hard or tough texture of pancreas (OR=2.240, 95%CI: 1.247-4.022, P=0.007), and main pancreatic duct diameter >3 mm (OR=1.931, 95%CI: 1.126-3.312, P=0.017) were independent prognostic factors for TO. Conclusion After the learning curve, more than 60% of patients with PDAC can achieve TO after LPD. The chances of achieving TO are significantly reduced when the operation time >360 min, the intraoperative blood loss >400 ml, the texture of pancreas was soft, and the diameter of the main pancreatic duct >3 mm.

Objective To investigate the post-intervention experiences in elderly stroke patients who received the group-based acceptance and commitment therapy(ACT)and to provide a reference to improve the group-based ACT intervention strategies for the patients.Methods With the descriptive phenomenological research,the semi-structured in-depth interviews were conducted with 15 elderly stroke patients who had received the group-based ACT intervention for 6 months in a Tier-IIIA hospital in Hunan Province between May and July 2023.The data acquired from the interviews were analysed using the Colaizzi method.Results The experiences in elderly stroke patients with the group-based ACT intervention were categorised into three main themes and ten sub-themes:(1)The impact of intervention on the psychology and spirit(change cognition and accept oneself;enhance awareness and reflect on oneself;clarify values and adapt to oneself;disengage from suffering and achieve dissociation;understand suffering and discover a sense of meaning in life);(2)Behavioural changes brought by the intervention(change approaches to improve health;engage in rehabilitation exercises and build confidence;enhance social interactions and integrate into life);(3)Suggestions for the intervention program(tailor to the physiological characteristics of the elderly;adapt to the psychological characteristics of the elderly).Conclusion The group-based ACT intervention has a beneficial effect on the psychological,spiritual and behavioural changes in the elderly stroke patients.The intervention programs should be improved according to the physical and mental characteristics therefore to improve the mental health of elderly stroke patients.

OBJECTIVE To establish skin contamination models with sulfur mustard analogue 1-chloro-2-ethylsulfanyl ethane(CEES),and evaluate the therapeutic efficacy of reactive skin decontamination lotion kit(RSDL).METHODS ①Kunming,BALB/c,BALB/c-nu,and C57BL/6N were contaminted with CEES 75 μL·kg-1 using exposed method and covered method for 10 min on the dorsal skin.Wound healing times and areas were assessed to determine the stock of mice and exposure method.② BALB/c mice were exposed to a gradient of CEES at the doses of 75,150,250,350 and 500 μL·kg-1(10 min)using the covered method.Wound healing times,areas and Kaplan-Meier survival curves were used to determine the optimal dose.③ BALB/c mice were exposed to CEES 150 μL·kg-1 for varying durations(5,10 and 20 min)using the covered method.Wound healing times,areas and Kaplan-Meier survival curves were analyzed to determine the optimal exposure time.④ BALB/c mice were divided into four groups:control(exposed with the covered method at 150 μL·kg-1,10 min),treatment(20 μL RSDL treatment after exposure,as the control group),5 min treatment(20 μL RSDL treatment after 5 min of exposure,followed by 5 min of coverage)and immediate-treatment(exposed with the exposed method at 150 μL·kg-1,immediately treated with 20 μL RSDL,followed by 10 min of coverage).The therapeutic efficacy was evaluated based on the wound area,subcutaneous microvesicle count,epidermal thick-ness,and inflammatory cytokine(IL-6 and TNF-α)expressions.RESULTS ① The covered method caused more severe and prolonged wounds than the exposed method.BALB/c mice exhibited a high sensitivity to CEES with delayed wound healing and were therefore selected as the model animal.② Survival rates in BALB/c mice dropped below 50%at doses of 250,350 and 500 μL·kg-1,whereas an 83.3%survival rate was observed at 150 μL·kg-1.③ The mice exposed to CEES(150 μL·kg-1,20 min)died within 3 days.The wound area was consistently smaller in the 5 min covered group than in the 10 min covered group.④CEES-induced skin injury led to epidermal nuclear pyknosis,follicular disrup-tion,inflammatory infiltration,and microvesicle formation in both treatment and poisoned control groups.As more immediate treatment,the wound area significantly decreased.While the IL-6 expres-sion showed no significant intergroup difference,the TNF-α expression was significantly higher in the treatment group.CONCLUSION A CEES-induced skin contamination model has been established in BALB/c mice using the covered method(150 μL·kg-1,10 min covered).However,RSDL should be ad-ministered in 10 min post-contamination.

Background and Aims:Pancreatic cancer is one of the most aggressive malignancies of the digestive system and is associated with an inferior prognosis.In recent years,its incidence has shown a trend toward younger onset.Early-onset pancreatic cancer(EOPC),defined as pancreatic cancer diagnosed at≤50 years of age,has been increasing annually and may possess distinct biological and prognostic characteristics.Given the limited data from China,this study aimed to investigate the clinicopathological features and prognostic outcomes of EOPC patients.Methods:Clinical data of 113 patients with EOPC admitted to Xiangya Hospital,Central South University,from January 2017 to December 2023 were retrospectively analyzed.Variables included demographic characteristics,clinicopathological features,and survival information.Kaplan-Meier survival curves were plotted,and differences in survival between the surgical and non-surgical groups were compared.Results:The median age at diagnosis was 46(42-49)years,and males accounted for 65.49%of cases.Blood type A(40.71%)and type O(34.51%)were most common.The main presenting symptoms were abdominal pain(69.91%),weight loss(62.83%),jaundice(43.36%),and abdominal distension(36.28%).Imaging findings showed bile duct dilation in 32.74%,pancreatic duct dilation in 39.82%,vascular invasion in 59.29%,and distant metastasis in 52.21%of patients.Histopathology revealed that adenocarcinoma and ductal adenocarcinoma accounted for 93.81%of all cases,with predominantly moderate or poor differentiation(76.10%).Tumors were the most frequently located in the pancreatic head(65.42%).TNM staging showed lymph node metastasis in 77.88%and stage Ⅳ disease in 52.21%.Laboratory tests demonstrated markedly elevated CA19-9 levels.Kaplan-Meier analysis indicated a median overall survival of 18.6 months for the entire cohort,with significantly longer survival in the surgical group compared with the non-surgical group(29.4 months vs.13.8 months,P=0.001 5).Conclusion:EOPC predominantly affects males and tends to arise in the pancreatic head.It is often diagnosed at an advanced stage or with distant metastasis and is characterized by poor differentiation and strong invasiveness.Surgical resection markedly improves survival and remains the key to prolonged prognosis.Young individuals presenting with unexplained abdominal pain,weight loss,or jaundice should be carefully evaluated through imaging to enable early diagnosis and timely surgical intervention.Future multicenter,large-sample prospective studies are warranted to validate these findings further.

In 2025,the International Association of Pancreatology(IAP),in collaboration with the American Pancreatic Association,European Pancreatic Club,Indian Pancreas Club,and Japan Pancreas Society,released the International Association of Pancreatology revised guidelines on acute pancreatitis 2025.This edition represents a comprehensive revision of the 2013 guidelines,based on high-quality evidence accumulated over the past decade,particularly randomized controlled trials.The guidelines encompass 18 key areas-including pain management,fluid therapy,nutritional support,management of infected necrosis,complication control,discharge and follow-up,and recurrence prevention-offering a total of 96 recommendations that emphasize individualized treatment.These updates provide important guidance for standardizing clinical practice and improving outcomes in acute pancreatitis,while also indicating future research directions such as the development of targeted therapies.However,some recommendations remain limited by lower evidence quality,uncertain applicability in specific clinical settings,and insufficient consideration of economic burden and cost-effectiveness.
