ObjectiveTo analyze the characteristics of 150 patients with spinal cord injury complicated with spasticity. MethodsA cross-sectional survey was conducted on 150 patients with spinal cord injury accompanied by spasticity from September, 2019 to December, 2024. Their age, gender, cause of injury, injury site, severity of injury, spasticity severity and other indicators were recorded. The relationships between different characteristics were analyzed, and a correlation analysis of disease duration, spasticity grade, injury level, injury severity and age were conducted. ResultsThere was no significant difference in age distribution between patients with tetraplegia and paraplegia (Z = 0.806, P = 0.420). The proportions of trauma (χ² = 3.982, P = 0.046) and tetraplegia (χ² = 10.559, P = 0.010) were higher in males than in females. Trauma was the main cause of injury in both tetraplegia and paraplegia patients; the proportion of tetraplegia was higher than paraplegia in trauma patients, while paraplegia was higher than tetraplegia in non-trauma patients (χ² = 11.885, P < 0.001). Patients with tetraplegia was dominated by incomplete injury, whereas patients with paraplegia was dominated by complete injury (χ² = 10.885, P = 0.012). Grade A injury was predominant in trauma patients (P = 0.003). Spasticity grade showed a very weak positive correlation with disease duration (r = 0.175, P = 0.032) and age (r = 0.168, P = 0.040). Injury severity showed a very weak positive correlation with age (r = 0.183, P = 0.025). ConclusionCharacteristics of patients with spinal cord injury complicated with spasticity is different with gender, cause of injury, injury level, injury severity.

Purpose To investigate the clinicopathological features and prognostic factors of follicular dendritic cell carcinoma(FDCS).Methods Hospital records of 23 patients diagnosed with FDCS were retrospectively re-viewed.The morphological,immunohistochemical features,including the detection of CD21,CD23,and CD35 using the EnVision method,and in-situ hybridization for Epstein-Barr virus encoded nuclear RNA(EBER)were evaluated.Clinicopathological characteristics were analyzed for the evaluation of prognosis.Results The median age of all 23 pa-tients was 50 years(range:27 to 72)and the female to male ratio was 1.3.The median maximum diameter of tumor was 7.0 cm(range:0.5 to 20.0 cm).One case was located in cervical lymph node,while another 22 were discovered in extranodal sites.20 cases were single organ and 3 cases were multiple organs involvement.Microscopically,tumor cells exhibited spindle,oval,or markedly pleomorphic morphology,accompanied by variable lymphoplasmacytic infil-tration in the stroma.CD21,CD35 and CD23 were positive in 22 of 23(95.6％),23 of 23(100.0％)and 4 of 15(26.7％)patients,respectively.EBER in-situ hybridization was positive in 9 of 23 patients(39.1％).The median follow-up time was 84.0(95％CI:50.7-117.3)months,and the 5-year survival rate was 80.2％(95％CI:62.8-97.6).Twelve(52.2％)patients were alive,5(21.7％)were dead,and 6(26.1％)were lost of follow-up.We es-tablished a pathological scoring system containing 5 indexes,i.e.,tumor maximum diameter,mitotic figures,tumor necrosis,cellular pleomorphism and histologic types.Patients with greater than 4 points had a significant poor progno-sis.Conclusion FDCS features a broad spectrum of histologic appearances and behavior.Combined morphological observations(HE staining),applications of a panel of follicular dendritic cell markers and EBER in-situ hybridization are helpful for accurate diagnosis.FDCS poses risks for recurrence,metastasis and death,and those with greater than 4 points in the scoring system have a significant poor prognosis.Long-term follow up is needed.

OBJECTIVES: This study aimed to investigate the potential mediating role of plasma phosphorylated tau217 (p-tau217) in the association between periodontitis and mild cognitive impairment (MCI). METHODS: In this case-control study, patients diagnosed with MCI in the Neurology Department of the First Affiliated Hospital of Shandong Second Medical University from November 2023 to May 2024 were selected as the case group (MCI group). Cognitively normal (CN) volunteers, matched for age and education level and recruited from the physical examination center during the same period, served as the control group (CN group). The general demographic data of the study participants were collected. The Beijing versions of the Montreal Cognitive Assessment (MoCA), clinical dementia rating (CDR), and activities of daily living scale (ADL) were used to assess neuropsychological functions. Clinical periodontal examinations were conducted, the periodontal inflamed surface area (PISA) was calculated, and the periodontitis stage was determined in accordance with the 2018 classification. Fasting elbow venous blood samples were collected in the morning, and blood biochemical indicators were measured. Plasma p-tau217 levels were detected using enzyme-linked immunosorbent assay (ELISA). Statistical analyses were performed using t-test, Mann-Whitney U test, chi-square test, partial correlation analysis, multivariate Logistic regression analysis, multiple linear regression analysis, restricted cubic spline (RCS) regression analysis, and mediation effect analysis. RESULTS: Among the 192 participants, 96 belong to the MCI group and 96 to the CN group. The prevalence of periodontitis was 63.5% in the MCI group and 43.8% in the CN group, with a statistically significant difference (χ²=7.561, P=0.006). The plasma p-tau217 levels in the MCI group were significantly higher than those in the CN group [7.00 (4.27-9.65) ng/mL versus 2.02 (0.80-3.81) ng/mL, Z=-8.108, P<0.001]. Partial correlation analysis revealed that plasma p-tau217 levels were positively correlated with all the clinical periodontal indices (all P<0.001). After adjustments for baseline covariates, multivariate Logistic regression indicated that periodontitis was an independent risk factor for MCI. Patients with periodontitis had a 1.977-fold higher MCI risk than those without periodontitis (OR=1.977, 95%CI: 1.088-3.594, P=0.025). Moreover, the MCI risk for stage Ⅰ/Ⅱ periodontitis and stage Ⅲ/Ⅳ periodontitis was 1.878 times (OR=1.878, 95%CI: 1.029-3.425, P=0.040) and 2.625 times (OR=2.625, 95%CI: 1.073-6.246, P=0.035) higher than that for patients without periodontitis, respectively. Trend test showed that the MCI risk increased with periodontitis severity (P_trend=0.016). After adjustments for baseline covariates, multiple linear regression analysis showed that periodontitis was an independent risk factor for increased plasma p-tau217 levels (β=3.309, 95%CI: 2.363-4.254, P<0.001). Compared with patients without periodontitis, those with stage Ⅰ/Ⅱ periodontitis (β=1.838, 95%CI: 0.869-2.806, P<0.001) and stage Ⅲ/Ⅳ periodontitis (β=5.539, 95%CI: 4.442-6.636, P<0.001) had significantly higher plasma p-tau217 levels. In addition, trend test indicated that plasma p-tau217 levels increased with periodontitis severity (P_trend<0.001). After adjustments for baseline covariates, RCS regression analysis further revealed that PISA had a positive linear dose-response relationship with MCI risk (P_overall=0.002, P_nonlinear=0.344) and plasma p-tau217 levels (P_overall<0.001, P_nonlinear=0.140). After adjustments for baseline covariates, mediation analysis showed that plasma p-tau217 mediated the association between periodontitis and MCI, with a mediation proportion of 13.99% (95% Bootstrap CI: 0.38%-49.39%, P=0.038). CONCLUSIONS Periodontitis was independently positively associated with MCI risk, and plasma p-tau217 plays a mediating role in this association.

Objective To explore the factors for chemotherapy-induced nausea and vomiting(CINV)in patients with advanced colorectal cancer receiving moderately emetic chemotherapy regimens.Methods 296 patients with colorectal cancer treated with oxaliplatin/irinotecan combination therapy and standard antiemetic prophylaxis regimen at the First Hospital of Jiaxing from July 1,2022 to June 30,2024 were selected,including 164 patients in oxaliplatin combination therapy group and 132 patients in irinotecan combination therapy group.Evaluated the nausea and vomiting status of patients within 5 days after the start of chemotherapy.Analyzed demographic data,medical history data,follow-up data.Results The incidence of CINV in oxaliplatin combination therapy group was 61.59％,and that in irinotecan combination therapy group was 53.79％.The incidence of delayed CINV and severe acute CINV in oxaliplatin combination therapy group were significantly higher than those in irinotecan combination therapy group(P＜0.05).Multivariate analysis showed that the risk factors for acute CINV in the oxaliplatin-based combination regimen were smoking history and CINV history.The risk factors for delayed CINV were age,no history of drinking,history of pregnancy-induced vomiting,motion sickness history,CINV history,and first use of the regimen.For the irinotecan-based combination regimen,the risk factors for acute CINV were motion sickness history and CINV history.The risk factors for delayed CINV were CINV history and anxious emotions.Conclusion When useing standard anti-emetic prophylaxis that still have a high incidence of CINV by moderate emetic chemotherapy drugs in advanced colorectal cancer patients.Patients with high risk factors should actively take preventive measures to control CINV.

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.
