ObjectiveTo evaluate the effect of neuromuscular electrical stimulation (NMES) on pain, quadriceps strength and motor function of patients after total knee arthroplasty (TKA). MethodsThe databases of CNKI, Wanfang data, VIP, PubMed, Embase, Cochrane, Web of Science and Scopus were retrieved from inception to April, 2025. Randomized controlled trials (RCT) related to the intervention of NMES after TKA were collected. The quality of the included literature was evaluated using the Cochrane Risk of Bias Assessment Tool and the Physical Therapy Evidence Database (PEDro) scale. Meta-analysis was performed with RevMan 5.4. ResultsA total of twelve RCT were included, involving 772 subjects. The PEDro scale score ranged from four to seven. NMES improved postoperative quadriceps muscle strength (SMD = 0.61, 95%CI 0.34 to 0.88, P < 0.001) and knee flexion range of motion (SMD = 1.35, 95%CI 0.30 to 2.41, P = 0.010), and reduced the Timed Up and Go Test (TUGT) time (SMD = -0.86, 95%CI -1.45 to -0.26, P = 0.005). Compared with the control group, the intervention group achieved better outcomes in the 2-Minute Walk Test (2MWT) (SMD = 19.44, 95%CI 10.44 to 30.43, P < 0.001), 3-Minute Walk Test (SMD = 23.57, 95%CI 14.77 to 32.36, P < 0.001), 6-Minute Walk Test (SMD = 42.29, 95%CI 9.71 to 74.86, P = 0.010), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (SMD = -0.52, 95%CI -1.00 to -0.04, P = 0.040), as well as the Physical Component Summary (PCS) (SMD = 2.90, 95%CI 0.73 to 5.06, P = 0.009) and Mental Component Summary (MCS) (SMD = 2.84, 95%CI 1.40 to 4.28, P = 0.040) of the 36-Item Short Form Health Survey (SF-36). Subgroup analysis demonstrated that two to four weeks after surgery, NMES enhanced patients' quadriceps muscle strength (SMD = 0.90, 95%CI 0.58 to 1.21, P < 0.001), shortened TUGT time (SMD = -1.28, 95%CI -2.57 to -0.02, P < 0.05) and increased walking distance in 2MWT (SMD = 20.43, 95%CI 10.44 to 30.43, P < 0.001). For patients followed up for two to three months, NMES yielded improvements in WOMAC scores (SMD = -0.44, 95%CI -0.79 to -0.09, P = 0.010) and SF-36 MCS scores (SMD = 4.17, 95%CI 2.43 to 5.91, P < 0.001). ConclusionNMES can significantly improve the quadriceps strength and walking ability of the TKA patients two to four weeks after surgery, and enhance the quality of life of patients two to three months after surgery.

ObjectiveTo investigate the effect of proprioceptive stimulation combined with shoulder strength training on cervical muscle morphology, vertebral artery hemodynamics, proprioception and motor function in healthy young men. MethodsThirty healthy young men recruited from Beijing Bo'ai Hospital between January, 2022 and June, 2024 were randomly divided into a proprioceptive stimulation (PS) group, a strength training (ST) group and a combined training (CT) group, with ten participants in each group. PS group received proprioceptive stimulation using suspension vibration, ST group received isometric contraction of the right shoulder joint in six directions, and CT group received both interventions concurrently, for four weeks. Before and after intervention, the cross-sectional area (CSA) of the right cervical multifidus, the end diastolic velocity (EDV) and peak systolic velocity (PSV) of the vertebral artery, cervical range of motion (ROM), isometric peak torque (IPT) and cervical joint position error (CJPE) were measured. ResultsAll 30 subjects completed the study, and no serious adverse events were reported. The time-by-group interaction in CSA was significant (F = 10.183, P = 0.001, partial η² = 0.430); CSA was higher in CT group than in PS group and ST group (P < 0.05). The time-by-group interactions in EDV and PSV were significant (F > 4.036, P < 0.05, partial η² > 0.230); PSV was significantly higher in CT group than in PS group and ST group (P < 0.001). The time-by-group interaction in extension ROM was significant (F = 54.277, P < 0.001, partial η² = 0.801); extension ROM was significantly higher in CT group than in PS group and ST group (P < 0.001). The time-by-group interactions in flexion, extension and lateral flexion IPT were significant (F > 14.251, P < 0.001; partial η² > 0.514); flexion IPT was higher in CT group than in PS group and ST group (P < 0.05). ConclusionIn healthy young men, proprioceptive stimulation combined with shoulder strength training can improve neck muscle strength, blood flow and motor function.

Objective:To analyze the changes of DNA methylation in peripheral blood mononuclear cells (PBMC) of patients with hepatocellular carcinoma (HCC) and to evaluate the clinical value of a combined model based on FSIP1 gene methylation on the early diagnosis of HCC.Methods:This is a case-control study. From May 2023 to September 2024, 183 HCC patients and 155 healthy controls were collected in Qilu Hospital of Shandong University. The selected study subjects were divided into three cohorts: 14 HCC patients and 39 healthy controls formed the discovery cohort, a screening cohort consisted of 36 HCC patients and 39 healthy controls, 133 HCC patients and 77 healthy controls were included in the model construction cohort. 935k methylation chip analysis was used to identify specific differentially methylated sites in peripheral blood PBMC of the discovery cohort. The absolute value of the average methylation level difference between HCC group and healthy control group (|Δβ|) and P value were calculated. Then targeted bisulfite sequencing was used to verify the differentially methylated sites in the screening cohort. Finally, based on MethylTarget methylation sequencing technology, differential methylation sites were further verified in model construction cohort (divided into training set and validation set, training set consisted of 99 HCC patients and 57 healthy controls; validation set consisted of 34 HCC patients and 20 healthy controls). HCC early diagnosis model was constructed by random forest algorithm combined with clinical parameters and the diagnostic performance of the model was evaluated by receiver operating characteristic (ROC) curve in the validation set. Results:The total of 7 249 differentially methylated sites between HCC patients and healthy controls in discovery cohort were selected under the rule of |Δβ|≥0.06 and P<0.01. Among them, the cg02155073 site located on FSIP1 was hypermethylated in PBMC of HCC patients in the screening cohort and model cohort ( P<0.001). The AUC of HCC early diagnosis model (FmAP) based on FSIPI in the validation set was 0.967 (95% CI 0.924-1.000); sensitivity was 88%, specificity was 95%. The model had good diagnostic efficacy for patients with early HCC, stage Ⅰ-Ⅱ HCC AUC was 0.958 (95% CI 0.898-1.000). The FmAP model also had diagnostic value for tumor size <2 cm HCC and AFP negative HCC, with AUC of 0.955 (95% CI 0.898-1.000) and 0.964 (95% CI 0.934-0.994).The sensitivity were 92% and 93% and specificity both were 84%. Conclusion:The FmAP model based on FSIP1 gene methylation has good clinical value for the early diagnosis of hepatocellular carcinoma.

Objective:To systematically evaluate the transitional care experience of family caregivers in palliative care from hospital to home.Methods:A computer-based search was conducted in PubMed, Web of Science, Cochrane Library, Embase, CINAHL, PsycINFO, SinoMed, China National Knowledge Infrastructure, VIP, and Wanfang Data for qualitative studies on the transitional care experience of family caregivers in palliative care, from database inception to November 25, 2024. The quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research (2016 edition). Data were synthesized and integrated using meta-aggregation.Results:A total of 10 studies were included, from which 33 primary findings were extracted. These findings were classified into nine new categories and further synthesized into four overarching themes: development and exacerbation of physical and psychological distress during the transition, multiple challenges and dilemmas during the transition, multidimensional support needs during the transition, and positive coping and personal growth.Conclusions:Family caregivers in palliative care experience complex physical and psychological changes, multiple challenges, and diverse care needs during the hospital-to-home transition. Healthcare professionals should pay close attention to the lived experiences and actual needs of family caregivers during this period, so as to facilitate a successful transition from hospital to home.

Objective:To compare the efficacy of various machine learning models in predicting renal function decline after robot-assisted partial nephrectomy(RAPN),and to provide evidence for clinical risk stratification.Methods:This study retrospectively in-cluded the clinical data of 733 patients with renal cell carcinoma undergoing RAPN at the Urology Department of The First Affiliated Hospital of Chongqing Medical University from January 2019 to December 2023.Demographic characteristics,laboratory indicators,and perioperative parameters were integrated to construct seven machine learning models.Key predictors were interpreted using Shap-ley additive explanations(SHAP).Model performance was evaluated using the area under the receiver operating characteristic curve(AUC).Results:The random forest model demonstrated the best predictive performance(AUC=0.84).SHAP analysis identified neutrophil-to-lymphocyte ratio,tumor diameter,the international normalized ratio of prothrombin time,white blood cell count,and in-traoperative blood loss as significant factors influencing postoperative renal function decline.Conclusion:This study provides a poten-tial predictive tool for clinical practice,aiding in identifying high-risk patients and optimizing postoperative management strategies.

Objective:To describe the application methods, types, and effects of wearable devices in sarcopenia.Methods:Following the guidelines for scoping reviews, a systematic search was conducted in PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure, Wanfang Data, and VIP for literature related to wearable device applications in sarcopenia. The search period covered publications from database inception to August 1, 2024.Results:A total of 12 studies were included. Wearable devices in sarcopenia were primarily used for monitoring gait speed, surface electromyography, sleep duration, activity time, and supporting exercise interventions. Common types of wearable devices included activity trackers, smart belts, and smart wristbands. Their effectiveness, feasibility, and role in ensuring activity safety have been preliminarily demonstrated.Conclusions:The application of wearable devices in sarcopenia is still in its early stages but shows great potential. Currently, wearable devices are mainly used to monitor one or a few individual indicators. Future research should focus on developing multi-parameter monitoring devices and conducting large-scale, high-quality trials to validate their effectiveness in both monitoring and supporting exercise interventions. This will help promote their broader application and assist healthcare professionals in the early identification, diagnosis, prevention, and treatment of sarcopenia.
