ObjectiveTo explore the effect of blood flow restriction training (BFRT) under different intensities combined with low-intensity resistance training (LIRT) on motor function in stroke patients with frailty. MethodsFrom August, 2024 to August, 2025, 200 elderly ischemic stroke patients with frailty from Affiliated Hospital, North China University of Science and Technology were randomized into control group and observation groups 1, 2 and 3, with 50 cases in each group. All the groups received 30% 1RM resistance training. In addition, the observation groups received BFRT of 40%, 50% and 60% arterial occlusion pressure (AOP), respectively. Before training, and four and eight weeks after training, their motor function was evaluated with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and Fugl-Meyer Assessment-Lower Extremities (FMA-LE), grip strength, 10-Metre Walk Test (10MWT) and Berg Balance Scale (BBS); Fried Frailty Phenotype (FFP) was used to assess frailty status; and the score of modified Ashworth Scale (MAS), blood pressure and resting heart rate were recorded. ResultsOne case dropped out in each group. For the scores of FMA-UE and FMA-LE, the grip strength of both hands, the time of 10MWT and the score of BBS, the main effects of group and time, and interaction effect were all significant (F > 2.745, P < 0.05); four weeks after training, the above indexes were better in the observation groups than in the control group (P < 0.05); eight weeks after training, the scores of FMA-UE and FMA-LE, the grip strength of both hand and the score of BBS were better in the observation group 3 than in the observation groups 1 and 2 (P < 0.05), and the time of 10MWT was better in the observation group 3 than in the observation group 1 (P < 0.05). For the score of FFP, the main effect of group was significant (F = 688.360, P < 0.001), however, the effects of time and interaction were not significant (P > 0.05). For the score of MAS, the main effect of group was significant (F = 7.171, P = 0.008), however, the effects of time and interaction were not significant (P > 0.05). For the blood pressure and resting heart rate, the main effects of group and time, and interaction effect were not significant (P > 0.05). ConclusionBFRT under different intensities combined with LIRT can safely improve the motor function, grip strength, walking ability in elderly stroke patients, and 60% AOP may be more effective.

AIM:To observe the changes of Th17 related cytokines in tears of conjunctivochalasis(CCH)patients with liver-kidney yin deficiency treated with traditional Chinese medicine Qi Jing Mingmu decoction combined with artificial tears.METHODS:A total of 56 CCH patients(56 eyes)with liver-kidney yin deficiency of grade Ⅱ to Ⅲ were collected and randomly divided into treatment group(treated with Qi Jing Mingmu decoction combined with artificial tears)of 26 cases(26 eyes)and control group(treated with pure artificial tears)of 30 cases(30 eyes). The treatment course was 1 mo, and international ocular surface disease index(OSDI), tear film break-up time(BUT), tear meniscus height(TMH)and conjunctival congestion index of the patients were observed before and after treatment. The patients' tears were collected before and after treatment, and Th17 related cytokines in tears were detected using flow cytometry immunofluorescence luminescence method.RESULTS:After treatment, the OSDI, BUT and conjunctival congestion index of CCH patients in the treatment group and control group were significantly improved(all P<0.01). After treatment, the TMH of CCH patients in the treatment group was significantly reduced(P<0.01), while there was no statistically significant difference in TMH of the control group before and after treatment(P=0.41). After treatment, the levels of Th17 related cytokines IL-17A, IL-22, IFN-γ, IL-17F, and IL-1β in tears of CCH patients in the treatment group were significantly reduced after treatment(all P<0.01), and the changes in the treatment group were more significant(all P<0.05). There was no significant difference in the control group before and after treatment(all P>0.05). After treatment, the levels of IL-6 and TNF-α in the tears of both groups of CCH patients decreased compared to those before treatment(both P<0.05), but the changes in the treatment group were more significant(both P<0.01).CONCLUSION:Qi Jing Mingmu decoction combined with artificial tears can effectively improve the ocular surface microenvironment, enhance tear film stability, and inhibit ocular surface inflammation in CCH patients with liver-kidney yin deficiency. This may be related to its reduction in the secretion of Th17 related cytokines in tears.

Objective To explore the factors influencing cognitive dysfunction in patients with vestibular migraines.Methods The clinical data of 298 patients with vestibular migraine admitted to the Second People's Hospital of Guiyang City from January 2020 to Ja-nuary 2024 were retrospectively analyzed.The patients were divided into a cognitive impairment group(n=55)and a non-cognitive impairment group(n=243).Baseline data such as sex,age,body mass index,and educational level between the two groups of patients were matched using propensity score matching in a 1∶1 ratio.Factors influencing cognitive dysfunction in patients with vestibular migraine were screened using single-factor and multiple logistic regression analyses.Results Fifty pairs of patients were successfully matched.Single-factor and multivariate logistic regression analyses showed that migraine duration≥10 years,sleep disorders,anxiety or depression,threatened migraine,and white matter lesions were risk factors for cognitive impairment in patients with vestibular migraine(P＜0.05).Conclusion Duration of migraine,sleep disorders,anxiety or depression,threatened migraine,and white matter lesions are factors influencing cognitive dysfunction in patients with vestibular migraine.Corresponding intervention strategies can be developed for risk factors to reduce the occurrence of cognitive dysfunction and improve prognosis.

OBJECTIVES: A ventricular assist device (VAD) is an electromechanical device used to assist cardiac blood circulation, which can be employed for the treatment of end-stage heart failure and is most commonly placed in the left ventricle. Despite enhancing perfusion performance, the implantation of left ventricular assist device (LVAD) transforms the local intraventricular flow and thus may increase the risk of thrombogenesis. This study aims to investigate fluid-particle interactions and thromboembolic risk under different LVAD configurations using three-dimensional (3D) reconstruction models, focusing on the effects of outflow tract orientation and blood flow rates. METHODS: A patient-specific end-diastolic 3D reconstruction model was initially constructed in stereo lithography (STL) format using Mimics software based on CT images. Transient numerical simulations were performed to analyze fluid-particle interactions and thromboembolic risks for LVAD with varying outflow tract orientations under 2 flow rates (4 L/min and 5 L/min), using particles of uniform size (2 mm), and a blood flow rate optimization protocol was implemented for this patient. RESULTS: When the LVAD flow rate was 5 L/min, helicity and flow stagnation of the blood flow increased the particle residence time (RT) and the risk of thrombogenesis of the aortic root. The percentage of particles traveling toward the brachiocephalic trunk was up to 20.33%. When the LVAD flow rate was 4 L/min, blood turbulence in the aorta was reduced, the RT of blood particles was shortened, and then the percentage of particles traveling toward the brachiocephalic trunk decreased to 10.54%. When the LVAD blood flow rate was 5 L/min and the direction of the outflow pipe was optimal, the RT of blood particles was shortened, and then the percentage of particles traveling toward the brachiocephalic trunk decreased to 11.22%. A 18-month follow-up observation of the patient revealed that the LVAD was in good working order and the patient had no complications related to the implantation of LVAD. CONCLUSIONS Implantation of LVAD results in a higher risk of cerebral infarction; When implanting LVAD with the same outflow tract direction, optimizing flow velocity and outflow tract can reduce the risk of cerebral infarction occurrence.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

ObjectiveSleep-related painful erections （SRPE） is a rare sleep disorder characterized by repeated awakening due to painful interruptions of penile erections during nighttime sleep， and its etiology is currently unclear. The purpose of this study is to explore the impact of potential risk factors on the incidence of SRPE. MethodsInformation was collected through questionnaires administered to patients who presented at the urology department and suffered from SRPE or did not suffer from SRPE. A total of 290 participants completed the study， including 145 controls and 145 cases. Logistic regression analysis was used to assess the impact of age， occupation， sleep initiation time per night， frequency of sexual intercourse per week， psychological status， erectile dysfunction， chronic prostatitis， prostate enlargement， lumbar spine disease， central nervous system disease， hypertension， diabetes and family history on the onset of SRPE. ResultsSingle-factor logistic regression analysis found that a history of chronic prostatitis， intellectual labor occupation， central nervous system disease， late sleep onset， frequency of sexual activity， and anxiety status might be related to the onset of SRPE. After incorporating these factors into a multivariate regression analysis model， it was found that having sexual activity ≥2 times/week （OR 95%CI = 0.326（0.179，0.592） and late sleep onset （after 24：00） （OR 95%CI = 0.494（0.265，0.918）might be protective factors for SRPE， while a history of chronic prostatitis（OR 95%CI = 3.779（2.082，6.859） might be a risk factor for SRPE. However， there was no significant statistical difference in the impact of central nervous system diseases and occupation on multivariate analysis. ConclusionChronic prostatitis and anxiety status may be independent risk factors for SRPE； having sexual activity ≥2 times/week and delaying sleep time appropriately may be independent protective factors.

Objective:To understand the cognition of the family caregivers of terminal cancer patients on digital health intervention, to clarify their actual needs, and to analyze the obstacles to their acceptance of digital health intervention, so as to develop a digital health intervention plan for the family caregivers of terminal cancer patients.Methods:From February 2024 to March 2024, the family caregivers of 16 patients with terminal cancer in Hunan Cancer Hospital Pain Hospice Ward were selected by objective sampling, who met the inclusion and exclusion criteria were interviewed in a semi-structured manner about the cognition and needs of digital health intervention, and the interview contents were sorted and analyzed using the Colaizzi7 step method.Results:A total of 16 family caregivers of terminal cancer patients, 4 males and 12 females, aged 26-55 years, were interviewed. Four themes were distilled from the interview results: family caregivers of terminally cancer patients agree on the importance of digital health interventions; lack of awareness of digital health interventions; expectations of digital health interventions; and possible confounders affecting digital health interventions.Conclusions:The family caregivers of terminal cancer patients had insufficient awareness of digital health intervention, but all showed affirmation of the development of digital health intervention services. It is recommended to actively improve the basic conditions of digital health services, strengthen publicity, raise the level of awareness of the family caregivers, and positively overcome the relevant interfering factors, so as to gradually promote the development of digital health services.
