Objective:To observe the efficacy and safety of micro-focusing ultrasound (MFU) combined with dye pulsed light (DPL) in the treatment of facial skin aging.Methods:A retrospective study was conducted in 133 patients treated for facial skin aging at Zhiyan Medical Beauty Clinic, the Fifth Affiliated Hospital of Guangzhou Medical University, and Sun Yat-sen Memorial Hospital of Sun Yat-sen University from May to September 2023. There were 46 males and 87 females, aged 24-45 (34.5±3.7) years. Patients were divided into two groups based on the treatment they received: combined treatment group: 55 cases, treated with MFU combined with DPL; control group: 77 cases, treated with MFU only. After the completion of treatment in all patients, three clinical physicians evaluated the pre-treatment and immediate post-treatment photos for efficacy, including improvement, deterioration, and ineffectiveness. The pain degree scores and skin reaction scores were compared between the two groups. The occurrence of adverse reactions was recorded.Results:After treatment, the improvement rate of all patients was 100 % (133/133). The pain score of the combined treatment group was 0.10 (0.05, 0.20) points, and that of the control group was 0.75 (0.60, 0.90) points. The difference was statistically significant between the two groups ( Z=-6.66, P<0.001). The skin reaction score of the combined treatment group was 0.40 (0.20, 0.60) points, and that of the control group was 1.20 (0.90, 1.50) points. The difference was statistically significant between the two groups ( Z=-5.18, P<0.001). There were no treatment site wounds and other serious adverse reactions during the treatment of all patients. Conclusion:MFU combined with DPL is effective in the treatment of facial skin aging without serious adverse reactions.

Objective To develop a tool for assessing the needs for care services for adults with disabilities in welfare institutions,and formulate criteria for classifying care needs.Methods Based on the theory of the International Classification of Functioning,Disability and Health,the core contents of domestic and international care service assessment standards were analysed,and the first draft of the assess-ment tool was formed integrating with the current practice of welfare institutions.A total of eleven experts in the field of care services validated the first draft,and the assessment tool was revised according to the experts'opin-ions.From May to June,2024,340 adults with disabilities from Second Social Welfare Institute of Shanghai were graded to analyze the reliability and validity of the assessment tool.And then,1 046 subjects from Second Social Welfare Institute of Shanghai were graded using the assessment tool,and the scoring intervals for the five levels of care were determined using cluster analysis.Results The assessment tool included four first-level dimensions,eleven second-level dimensions,39 third-level dimen-sions and 43 indicators.The coefficients of variation of each dimension and indicator were less than 0.25 for ex-pert validation,while the average score of the importance of each indicator was above 4.63,with a full score rate more than 0.86.The overall Cronbach's α coefficient was 0.956,the test-retest reliability was 0.997,and the con-tent validity index of each indicator was 0.83 to 1.00.The exploratory factor analysis extracted four common fac-tors,with a cumulative variance contribution of 86.679%;the loading coefficients of indicators were 0.675 to 0.878,and the correlation coefficients among the dimensions were 0.325 to 0.476.Cluster analysis determined the level of institutional care needs as level 1(severe),level 2(medium-heavy),level 3(medium),level 4(light-moderate),and level 5(light).Conclusion The needs assessment tool for care services for adults with disabilities in welfare institutions developed in this study is good in reliability and validity,and can be used in guiding the care services provided for people with disabilities more efficient and targeted.

Objective To investigate the clinical efficacy of the"dynamic and static combination"approach in the treatment of Hepple Ⅰ-Ⅲ type osteochondral lesions of the talus(OLT),utilizing external ankle shaking,pulling,and poking manipulations in conjunction with ankle brace fixation.Methods A total of 82 patients diagnosed with OLT,who sought treatment at four hospitals between June 2022 and December 2023,were included in the study.Both the experimental and control groups received ankle immobilization using braces through-out the treatment period.The control group was administered Voltaren Emulgel topically twice daily(morning and evening),with each treatment course lasting 30 days,for a total of one course.The experimental group received additional therapeutic intervention involving shaking,pulling,and poking manipulations,conducted twice weekly,with the same duration and number of treatment courses as the control group.Follow-up assessments were scheduled at 2 weeks,4 weeks,and 2 months post-treatment.Outcome measures included the pain rating index(PRI),visual analogue scale(VAS)for pain intensity,current pain intensity(PPI),American Orthopaedic Foot & Ankle Society(AOFAS)ankle and hindfoot scores,proprioceptive function,and the size of OLT.Results During the longitudinal assessment conducted at 2-week,4-week,and follow-up intervals,the experimental group exhibited superior clinical outcomes compared to the control group,with statistically significant decreases in PRI,PPI,and AOFAS scores(all P＜0.05).VAS scores showed progressive improvement over time,with significant intergroup differences observed at both the 4-week and follow-up assessments(P＜0.05).Biomechanical analysis performed post-intervention indicated improved kinematic repositioning accuracy in the experimental group,as reflected by significantly reduced active-passive error angles(P＜0.05).Importantly,measurements of OLT area revealed notable therapeutic effects in the experimental group(P＜0.05),whereas no statistically significant changes were observed in the control group throughout the study period(all P＞0.05).Conclusions Under the guidance of the"dynamic and static combination"concept,the integration of shaking,pulling,and poking manipu-lation with conventional Western medicine-based conservative treatment for OLT demonstrates more pronounced advantages in alleviating pain,improving ankle joint function,restoring proprioception,facilitating lesion recovery,and enhancing overall quality of life.

Objective:To investigate the clinical and genetic features of a Chinese pedigree with Progressive familial intrahepatic cholestasis (PFIC) and explore its genotype-phenotype correlation.Methods:A patient with PFIC diagnosed at Xinxiang Central Hospital in 2023 was selected as the study subject. The patient was subjected to abdominal magnetic resonance imaging (MRI) and painless gastroscopy. Peripheral blood samples were collected from the patient and his parents for the extraction of genomic DNA and trio-whole exome sequencing (trio-WES). Candidate variants were verified by Sanger sequencing. This study has been approved by the Medical Ethics Committee of Xinxiang Hospital (Ethics No. 2023-241).Results:MRI scan showed that the patient had significantly enlarged liver and spleen. WES revealed that he has harbored compound heterozygous variants of the ATP8B1 gene, including a c. 1710_1711insCCTC (p.A571Pfs*12) frameshifting variant in exon 16 and a c. 2989G>A (p.V997M) missense variant in exon 24, which were respectively inherited from his father and mother, and rated as pathogenic (PVS1+ PM2_Supporting+ PM3+ PP1) and likely pathogenic (PM2_Supporting+ PM3+ PP1) based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). Conclusion:WES can clarify the genetic etiology of patients with speed and accuracy, and facilitate clinical decision-making. The detection of pathogenic variants has provided a basis for clinical diagnosis and enriched the mutational spectrum of the ATP8B1 gene.

Objective To explore the risk factors for very early recurrence (VER) after curative-intent resection for gallbladder cancer (GBC) patients and construct prediction models for VER based on various machine learning (ML) algorithms. Methods A retrospective study was conducted on 329 GBC patients who underwent curative-intent surgery at our hospital between January 2016 and December 2020. Risk factors for VER were identified, and prediction models were constructed, validated and compared with multiple ML algorithms[logistic regression (LR), support vector machine (SVM), naive Bayes (NB), random forest (RF), light gradient boosting machine (LGB), and extreme gradient boosting (XGB)]based on independent associated factors for VER. Results Among the 329 patients who underwent curative-intent resection in patients with GBC, 162 (49.2%) patients experienced recurrence, including 69 (42.6%) with VER（<6 months） and 93 (57.4%) with non-VER（≥6 months）. Survival analysis showed that patients with VER had significantly worse median overall survival compared to those with non-VER (6 months vs. not arrived，χ2=398.2, P<0.001). Univariate analysis showed that carcinoembryonic antigen (CEA), carbohydrate antigen (CA)19-9, CA-125, tumor differentiation, pathological type, liver involvement, vascular invasion, perineural invasion, TNM stage, T stage and N stage were risk factors of VER (P<0.05), whereas adjuvant chemotherapy was protective factor (P<0.05). Multivariate analysis confirmed CA-125, tumor differentiation, pathological type, vascular invasion and N stage as independent risk factors (P<0.05), whereas adjuvant chemotherapy was independent protective factor (P<0.05). XGB model achieved the best performance with an area under curve (AUC) of 0.841 and an accuracy (ACC) of 83.0% in the validation set. Shapley additive explanations (SHAP) bar plots highlighted tumor differentiation, N stage, pathological type of tumor, and CA-125 the top four features contributing to the model, each positively influencing the predicted probability of VER. Conclusions CA-125, tumor differentiation, pathological type, vascular invasion, N stage and adjuvant chemotherapy are independent factors associated with VER of GBC following curative-intent resection. ML-based prediction models incorporating these factors have the potential to some extent to effectively identify high-risk patients, providing a valuable reference for VER surveillance in GBC.

Objective:To investigate the current state of death cognition among healthcare providers in hematology department and their attitudes toward hospice care for patients with hematologic malignancies.Methods:A cross-sectional investigation study was conducted. A total of 198 medical staff in hematology department of 4 teaching hospitals, including the First School of Clinical Medicine of Guangdong Medical University, Fujian Medical University Union Hospital, the Affiliated Hospital of Putian University and the First Affiliated Hospital of Gannan Medical University from March 2024 to June 2024 were selected as the investigation subjects. The general situation and background of medical staff in hematology department were investigated by using the "General Sociological Questionnaire". "Death Attitude Description Scale (Chinese version)" was used to investigate the status of death cognition among medical staff in hematology department. "Frommelt Attitudes Toward Care of the Dying Scale Form B (Chinese version)" was used to investigate the hospice care attitude of medical staff in hematology department. The survey results of doctors and nurses were compared.Results:There were 105 doctors and 93 nurses in hematology department included in this study. A total of 198 qualified "General Sociology Questionnaires" were collected. After excluding 6 unqualified questionnaires, 192 copies of "Death Attitude Description Scale (Chinese version)" and "Frommelt Attitudes Toward Care of the Dying Scale Form B (Chinese version)" were collected. There were statistically significant differences in gender, educational background, political status and experience of taking care of terminally ill patients between doctors and nurses (all P < 0.05). The scores of approaching acceptance, neutral acceptance, death escape, death fear and flight acceptance were (4.35±0.37), (4.03±0.51), (2.98±0.62), (2.54±0.29) and (2.19±0.42) points, respectively in the doctor group; the corresponding scores were (3.12±0.41), (3.89±0.46), (2.66±0.63), (2.81±0.57) and (2.37±0.65) points, respectively in the nurse group, and the differences between the 2 groups were statistically significant (all P < 0.05). The total score of hospice care attitude of doctors in hematology department was (108±15) points, and that of nurses was (116±13) points, and the difference was statistically significant ( t = -3.61, P < 0.001). The hospice care attitude of doctors and nurses towards patients with hematologic malignancies is generally between positive and neutral. The nurse group showed more recognition of the positive role of the patient's family members in the process of hospice care, and the doctor group showed more recognition of the promoting role of medical staff in hospice care. There were statistically significant differences in hospice care attitude scores of medical staff in hematology department to patients with different occupational background, gender, age, place of residence, family discussion about death, whether the only child, whether they had the experience of taking care of terminally ill patients, and whether they suffered from serious illness and religious belief (all P < 0.05). Conclusions:The death cognition of medical staff in hematology department is neutral, and they show a certain sense of hospice care.

Objective:To explore differences in the clinical and pathological features and postoperative survival after radical resection of biliary tract cancer in different locations such as intrahepatic cholangiocarcinoma,perihilar cholangiocarcinoma,distal cholangiocarcinoma,and gallbladder cancer.Methods:This is a retrospective case series study. The clinical and pathological data of 4 852 patients with biliary tract cancer admitted to the Department of Hepatobiliary Surgery,the First Affiliated Hospital of Xi ′an Jiaotong University from January 2013 to December 2022 were retrospectively analyzed. Among them, 2 110(43.49%%) patients were male and 2 742(56.51%) patients were female,aged from 26 to 88 years with age of (61.3±10.8) years. Observation indicators: (1) The distribution,diagnosis and treatment of patients with biliary tract cancer; (2) Comparison of clinical and pathological features of patients with biliary tract cancer after curative-intent resection; (3) Survival analysis of patients with biliary tract cancer after curative-intent resection; (4) Analysis of effect on adjuvant therapy for patients with biliary tract cancer after curative-intent resection. One-way analysis of variance,Kruskal-Wallis H test and χ 2 test were used for among-group comparisons,respectively. Survival univariate analysis was performed using the Kaplan-Meier method and Log-rank test. Results:Among the 4 852 patients with biliary tract cancer,there were 2 303 cases (47.46%) of gallbladder cancer,952 cases (19.62%) of intrahepatic cholangiocarcinoma,892 cases (18.38%) of perihilar cholangiocarcinoma,and 705 cases(14.53%) of distal cholangiocarcinoma. From the perspective of the year of diagnosis and treatment,the overall number of patients diagnosed and treated for biliary tract cancer has shown an upward trend. From the perspective of diagnosis and treatment,the curative-intent resection rate was 33.37%(1 619/4 852),and the curative-intent resection rate of distal cholangiocarcinoma was higher than that of other biliary tract cancer ( χ2=23.897, P<0.01). Univariate analysis showed that there were statistical differences in gender,age,bile duct stones,total bilirubin at admission,carcinoembryonic antigen,CA19-9,CA125,the degree of pathological differentiation,vascular invasion,microvascular invasion,perineural invasion,surgical margins,pT staging,and pN staging among patients for biliary tract cancer in different locations (all P<0.05). Survival comparison analysis showed that recurrence-free survival and overall survival of patients with gallbladder cancer after curative-intent resection were significantly better than those of intrahepatic cholangiocarcinoma,perihilar cholangiocarcinoma,and distal cholangiocarcinoma ( χ 2=87.780,83.717,both P<0.01). Comparing the postoperative prognosis of patients with biliary tract cancer between the two periods of 2013 to 2017 and 2018 to 2022, the results showed that recurrence-free survival and overall survival of patients with biliary tract cancer from 2018 to 2022 were significantly better than those from 2013 to 2017 ( χ 2=31.202,25.615, both P<0.01),and the proportion of early recurrence and short-term death after curative-intent resection was significantly reduced ( χ 2=21.588,9.623, both P<0.01),with gallbladder cancer being the most significant ( P<0.01). Postoperative adjuvant therapy for patients with biliary tract cancer can effectively prolong recurrence-free survival and overall survival ( χ 2=5.033,11.273,both P<0.05). Conclusions:Gallbladder cancer remains the most common biliary tract cancer with a relatively favorable prognosis after radical resection. There are significant differences in the clinical and pathological features of biliary tract cancer in different locations,and patients with adjuvant therapy effectively improving prognosis.

Objective To observe the value of intratumoral and peritumoral CT radiomics combined with clinic for predicting cervical lymph node metastasis(CLNM)of papillary thyroid carcinoma(PTC).Methods Totally 338 patients with PTC were retrospectively enrolled and divided into training set(n=236)and validation set(n=102)at a ratio of 7∶3,also further assigned into subgroups according to CLNM or not within sets.The clinical independent risk factors for PTC CLNM were identified using multivariate logistic regression analysis,and a clinical model was then constructed.Intratumoral ROI were delineated on CT images including non-enhanced and three-phase enhancement images,which were then enlarged by 2 mm.Radiomics models of intratumoral,peritumoral and intratumoral+peritumoral ROI were established based on non-enhanced CT,as well as arterial phase,venous phase,delayed phase and multi-phase enhanced CT,respectively,the best one was selected and combined with clinical model to construct a combined model.Receiver operating characteristic curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficacy of each model for predicting PTC CLNM.Results Male patient and aged＜45 years were both clinical independent risk factors for PTC CLNM(both P＜0.05).Multi-phase intratumoral+peritumoral radiomics model was the optimal radiomics model,which was used to construct the combined model combining with clinical model.The AUC of combined model for predicting PTC CLNM in training set was 0.859,superior to that of clinical model and multi-phase intratumoral+peritumoral radiomics model(0.684,0.831,both P＜0.05),which in validation set was 0.832,similar to that of multi-phase intratumoral+peritumoral radiomics model(0.819,P=0.368)but superior to that of clinical model(0.605,P＜0.001).Conclusion Multi-phase intratumoral and peritumoral CT radiomics could be used to predict PTC CLNM.Combining with clinic could further improve its efficacy.

Purpose To evaluate the value of arterial-phase CT-based radiomics and habitat imaging models in predicting programmed death ligand 1(PD-L1)expression levels in non-small cell lung cancer(NSCLC).Materials and Methods Clinical and imaging data from 258 pathologically confirmed NSCLC patients at Yijishan Hospital of Wannan Medical College from April 2022 to May 2024 were retrospectively analyzed.Patients were randomly divided into training(n=207)and validation(n=51)sets at a 4∶1 ratio.Whole-lesion radiomic features were extracted from arterial-phase CT images.Subregional habitats were generated using local feature clustering,and their radiomic features were fused to derive habitat analysis features.Dimensionality reduction identified features for constructing whole-lesion radiomic and habitat analysis models.Logistic regression algorithms were used to build models and develop nomograms.Model performance was evaluated using the area under the receiver operating characteristic curve(AUC),and clinical utility was assessed via decision curve analysis.Results Two independent clinical risk factors(tumor location and necrosis presence),14 whole-lesion radiomic features and 16 habitat analysis features were selected.The clinical model achieved AUCs of 0.685(training)and 0.682(validation).The habitat analysis model(AUC:0.776 training,0.761 validation)outperformed the whole-lesion radiomic model(AUC:0.701 training,0.647 validation).The combined model integrating clinical,whole-lesion and habitat analysis features demonstrated superior performance(AUC:0.838 training,0.826 validation)and the highest clinical net benefit on decision curve analysis.Conclusion Habitat imaging features derived from arterial-phase CT effectively predict PD-L1 expression in NSCLC.Combining clinical characteristics with whole-lesion and habitat analysis features further enhances predictive performance.
