Hand degloving injury represents one of the most severe forms of hand trauma, characterised by challenging treatment and a complex prognostic outcome. It is crucial to effectively utilise the degloved tissues in emergency or primary repair of a hand degloving injury. This consensus provides a comprehensive review of the existing literature on definition, classification, emergency assessment, debridement, judgment of skin viability, in situ repair of the degloved skin, and adjunctive treatment for degloving injury of hand. Based on conclusion of both domestic and international experiences, this expert consensus on the classification of hand degloving injury and the emergency repair with the avulsed skin is established, aiming to provide a guidance to surgeons on standardised treatment strategy and improve the management of hand degloving injury.

Objective:To explore the split-face phenomenon in patients with bulbar-involved amyotrophic lateral sclerosis (ALS) through clinical and electrophysiological studies.Methods:A total of 52 clinically definite and clinically probable cases of bulbar-involved ALS, diagnosed according to the World Federation of Neurology El Escorial criteria, were retrospectively collected in the Third Central Hospital of Tianjin from September 2019 to November 2022. And 58 patients with idiopathic facial nerve paralysis with onset time≤7 days who visited the Department of Neurology of the Third Central Hospital of Tianjin during the same period were collected as control group. The firm eye closure (FC) score and cheek bulge (CB) score were used to assess the clinical involvement of facial muscles (dividing into facial muscle involvement group and non-facial muscle involvement group) and the presence of the split-face phenomenon (strong eye closure and weak cheek bulging) in ALS patients. The compound muscle action potential (CMAP) amplitudes of the bilateral orbicularis oculi and orbicularis oris muscles were measured using the Nicolet EDX Viking electromyography/evoked potential system. The CMAP amplitude ratio was calculated. The facial nerve electrophysiological differences were compared between ALS patients with bulbar involvement and patients with idiopathic facial nerve paralysis. The analysis of electrophysiological data across various groups was carried out utilizing the Kruskal-Wallis H test, while pairwise comparisons between groups were executed employing the Bonferroni correction method. Additionally, a stepwise binary Logistic regression analysis was implemented to ascertain the factors associated with facial muscle involvement in patients with bulbar-involved ALS. The receiver operating characteristic (ROC) curve was used to assess the diagnostic accuracy of facial nerve electrophysiological testing in diagnosing ALS in the presence of symptoms of facial muscle involvement. Results:Among the 52 ALS patients with bulbar involvement, there were 20 cases (38.5%) with facial muscle involvements, all of which were bilateral; 16 patients (30.8%) exhibited weakness solely in the ability to puff their cheeks, 1 patient (1.9%) presented with weakness exclusively in closing the eyes, and 3 patients (5.8%) experienced weakness in both closing the eyes and puffing the cheeks. The Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score of the facial muscle involvement group was lower compared to the non-facial muscle involvement group (36.90±9.20 vs 40.75±5.21, t=2.419, P=0.019), while the FC score and CB score were higher in the facial muscle involvement group [FC score: 0(0, 1) vs 0(0, 0), U=5.854, P<0.001; CB score: 4(3, 4) vs 0(0, 0), U=9.069, P<0.001], showing statistically significant differences. There was no statistically significant difference in the CMAP amplitude of the orbicularis oculi muscle between the facial muscle involvement group and the healthy side of the idiopathic facial nerve paralysis group, the affected side of the idiopathic facial nerve paralysis group, and the non-facial muscle involvement group (all P>0.05). The CMAP amplitude of the orbicularis oris muscle in the facial muscle involvement group [1 100.00 (775.00, 1 375.00) μV] was lower than that in the healthy side of the idiopathic facial nerve paralysis group [1 800.00 (1 400.00, 2 300.00) μV] and the non-facial muscle involvement group [1 555.00 (1 202.50, 1 980.00) μV], with statistically significant differences ( H=5.884, P<0.001; H=4.114, P<0.001). There was no statistically significant difference in the CMAP amplitude of the orbicularis oris muscle between the facial muscle involvement group and the affected side of the idiopathic facial nerve paralysis group ( P>0.05). The CMAP amplitude ratio of the orbicularis oculi/orbicularis oris muscles in the facial muscle involvement group [0.83(0.51, 1.14)] was higher than that in the healthy side of the idiopathic facial nerve paralysis group [0.55(0.39, 0.73)], the affected side of the idiopathic facial nerve paralysis group [0.57(0.40, 0.73)], and the non-facial muscle involvement group [0.60(0.42, 0.71)], with statistically significant differences ( H=-3.440, P=0.003; H=-3.433, P=0.004; H=-3.225, P=0.008). Logistic regression analysis revealed that the CMAP amplitude of orbicularis oris muscle ( OR=0.998,95% CI 0.997-0.999, P<0.001) and ALSFRS-R score ( OR=0.916,95% CI 0.857-0.979, P=0.010) were factors associated with facial muscle involvement in ALS patients with bulbar involvement. The ROC curve analysis results showed that the area under the curve (AUC) of the orbicularis oculi muscle CMAP was 0.629, the AUC of the orbicularis oris muscle CMAP was 0.838, and the AUC of the CMAP amplitude ratio of the orbicularis oculi/orbicularis oris muscles was 0.690 in the facial muscle involvement group. Conclusions:Patients with bulbar-involved ALS have split-face phenomenon characterized by strong eye closure and weak cheek bulging. When bulbar-involved ALS patients have symptoms of facial muscle involvement, the CMAP amplitude of the orbicularis oris muscle decreases significantly, whereas the CMAP amplitude of the orbicularis oculi muscle remains relatively stable, further illustrating the split phenomenon.

Objective:To analyze the clinical and electrophysiological characteristics of patients with sensory neuronopathies (SNN), and to evaluate the significance of electrophysiological markers in the diagnosis and assessment of disease progression.Methods:A retrospective analysis was performed to evaluate the clinical manifestations, electrophysiological characteristics, and spinal cord magnetic resonance imaging (MRI) features of 8 cases diagnosed with SNN at the Third Central Hospital of Tianjin between 2015 and 2023. The neurophysiological examination mainly included limb nerve conduction study (NCS), same core needle electrode electromyography, somatosensory evoked potential (SEP), skin sympathetic reflex (SSR), and contact heat evoked potential (CHEP).Results:Among the 8 cases with SNN, 7 cases exhibited asymmetrical onset and a non-length-dependent pattern. All the 8 cases presented with severe deep sensory ataxia, accompanied by superficial sensory abnormalities and tendon areflexia. Paraneoplastic SNN were the most prevalent etiological subtype (4 cases), all of whom presented peripheral neuropathy as the initial symptom. Among these 4 cases, malignancies were identified in 3 cases and 3 cases presented with anti-Hu antibodies. Among the remaining 4 patients, 2 cases were autoimmune and the other 2 cases were idiopathic. NCS results of the 8 cases revealed decrease or absence of sensory nerve action potential (SNAP) amplitudes, with normal sensory conduction velocities. Six cases showed abnormal SEP, including 2 cases of central damage and 4 cases of peripheral damage, 5 cases had abnormal SSR, and 2 cases exhibited abnormal CHEP. Motor nerve conduction studies were normal in all 8 cases. Six patients underwent spinal MRI, and 4 exhibited abnormal signals in dorsal columns.Conclusions:The hallmark clinical manifestation of SNN is sensory ataxia, characterized by substantial impairment of superficial sensation, typically manifesting in a non-length-dependent distribution. Beyond the widespread and significant reduction in SNAP amplitudes, SNN may also exhibit additional electrophysiological impairments, such as those observed in SEP, SSR and CHEP.SEP combined with spinal cord MRI can improve the detection rate for damages in the central sensory conduction pathway.

Objective:This study aims to analyze historical trends and predict future trends of disability-adjusted life years (DALYs) attributable to high BMI for osteoarthritis (OA) in China. OA is a common chronic degenerative joint disease, with high body mass index (BMI) being a significant risk factor. in China.Methods:Based on the Global Burden of Disease (GBD) 2021 database, we analyzed trends in high-BMI-attributable OA. The ASR of hogh-BMI-attributable OA DALYs increased from DALYs in China from 1990 to 2021. A Bayesian age-period-cohort (BAPC) model was used to predict trends from 2022 to 2046. Age-standardized rates (ASR) and estimated annual percentage changes (EAPC) were calculated to assess trend changes of trends. A Bayesian age-period-cohort (BAPC) model was used to predict trends from 2022 to 2046. Chi-square tests were used to compare differences in high BMI attribution proportions between regions and years.Results:From 1990 to 2021, China′s OA DALYs increased from 1.829 to 5.327 million, with the proportion attributable to high BMI rising from 13.47% to 21.86% ( χ2=60 527.25, P<0.001). The ASR of high-BMI-attributable to OA increased from 27.4 (-2.2, 81.5) per 100,000 to 53.0 (-4.7, 150.7) per 100 000, with an EAPC of 2.48% [95% (uncertainty interval, UI): 2.35, 2.62]. In 2021, females showed significantly higher ASR (69.2 per 100 000) than males (36.1 per 100 000). Knee OA (ASR: 50.5/100 000) demonstrated substantially higher burden than hip OA (ASR: 2.5/100 000). Age effect analysis showed DALYs peaked at ages 80~90; period effect indicated accelerated growth after 2005; cohort effect showed a U-shaped trend with the 1990 birth cohort having the highest relative risk (approximately 3.0). Projections indicated that up to 2046, total OA DALYs will reach approximately 2.39 million with an ASR of about 71, showing more significant growth among females (ASR reaching 100). Conclusion:High-BMI-attributable to OA DALYs in China shows a significant upward trend, and is expected to continue. This trend is more pronounced among females and elderly populations than males, highlighting the urgency of implementing preventive measures for high-risk groups, particularly in weight management.

Objective:To investigate changes in the density and spatial distribution of CD69 + T cells within hepatocellular carcinoma tissues following immune checkpoint blockade (ICB) therapy, and to explore their correlation with tumor infiltrating immune cell. Methods:Tumor specimens were collected from 12 patients with hepatocellular carcinoma who were admitted to the Department of Hepatobiliary and Pancreatic Surgery of People's Hospital of Zhengzhou University and the First Affiliated Hospital of Zhengzhou University from July 2023 to July 2024. There were 10 males and 2 females, aged (58.5±5.6) years. Of the 12 patients, 6 cases underwent radical surgery directly and 6 underwent radical surgery after immunotherapy. The maximum tumor diameter and tumor volume of the immunotherapy group were measured by imaging. The density and distribution of immune cells such as CD8 + CD69 + T, CD4 + CD69 + T and programmed death-1 (PD-1) were detected by immunohistochemistry and immunofluorescence. The number of immune cells around the target cells was calculated to evaluate the effective score, and the intercellular distance was measured to evaluate the intercellular interaction. Results:The maximum tumor diameter and tumor volume of 6 patients after immunotherapy were lower than before treatment, and the differences were statistically significant (all P<0.05). The density of PD1 + cells in the immunotherapy group was 36.6 (25.9, 55.9) cells/mm 2, which was less than that in the control group 53.9 (38.3, 84.5) cells/mm 2, and the difference was statistically significant ( Z=-2.66, P=0.008). In the control group, the number of CD8 + CD69 + T cells was positively correlated with CD8 + PD1 + T cells and CD8 + PD1 + CD103 + T cells, and the correlation coefficients were 0.42 and 0.40, respectively ( P=0.001, 0.002). The effective scores of CD8 + CD69 + T cells and CD8 + PD1 + T, CD4 + CD103 + T, CD4 + PD1 + CD103 + T and CD8 + PD1 + CD103 + T cells in the above three areas in the immunotherapy group were lower than those in the control group, with statistical significance (all P<0.05). The distance between CD8 + CD69 + T and CD4 + CD69 + CD103 + T cells in the interface area of the control group was closer than that of the immunotherapy group, and the difference was statistically significant ( t=2.67, P=0.009). Conclusion:After immunotherapy in hepatocellular carcinoma patients, PD-1+ cells and immune cells around CD8 + CD69 + T cells decreased, and this change was related to the distance between CD8 + CD103 + T cells.

Additionally, the popularization and usage of HBPT as well as needs of patient management were investigated and analyzed in these vitiligo patients.Results:A total of 496 valid questionnaires were collected from 496 patients with vitiligo (241 males [48.5%] and 255 females [51.5%]) . Their ages at visit ranged from 2 to 67 (30.87 ± 12.36) years. The most commonly affected sites were the head and face (52.2%) , followed by hair (32.1%) , hands and feet (31.4%) , trunk (30.2%) , limbs (24.3%) , neck (19.5%) , and perineum (9.9%) . Among the participants, 320 (64.5%) were currently using or had used HBPT, and 352 (70.8%) expressed a willingness to learn more about HBPT usage guidelines and health education. Regarding the repigmentation outcomes after HBPT: among 312 patients, 54 (17.3%) reported complete recovery, 64 (20.5%) were markedly improved, 142 (45.5%) experienced improvement, and 52 (16.7%) showed no response. Adverse reactions occurred in 223 patients (71.5%) , of whom 28 (9.0%) experienced severe adverse reactions. The most desired guiding information was the adjustment method for phototherapy dosage and treatment duration (184/352, 52.3%) ; the most effective way to receive health education information was through verbal education by medical staff (177/352, 50.3%) .Conclusion:For vitiligo patients who were willing to accept and use HBPT, the most desired guiding information was the adjustment method for phototherapy dosage and treatment duration, and verbal health education by medical staff appeared to be the main way to obtain health education information.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

OBJECTIVE: To analyze the time characteristics of the Ethos online adaptive radiotherapy (OART) process in clinical practice and provide guidance for the comprehensive optimization of each stage of adaptive radiotherapy. METHODS: The study involved 61 patients with cervical, rectal, gastric, lung, esophageal, and breast cancers who underwent Ethos OART. The mean ± standard deviation of segmental time, total time, and target volume for these patients were tracked. The time characteristics for different cancer types were evaluated, and the average time for target and organ at risk (OAR) modifications was compared with the average target volume for each cancer type. RESULTS: Cervical cancer born the longest total treatment time, while breast cancer had the shortest. For all cancer types except breast cancer, the modification time for target and OAR was the most time-consuming segment. The average time for target and OAR modifications aligned with the trend of the average target volume. CONCLUSION The total treatment time for various cancers ranges from 15 to 35 minutes, indicating room for improvement.
