ObjectiveTo investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on prolonged disorders of consciousness (pDoC) after stroke. MethodsSixty patients with pDoC admitted to Zhejiang Provincial People's Hospital from January to July, 2024 were randomly assigned into control group (n = 30) and observation group (n = 30). Both groups received conventional rehabilitation therapy combined with hyperbaric oxygen therapy, while the observation group received rTMS in addition, for four weeks. Before and after treatment, they were assessed with Coma Recovery Scale-Revised (CRS-R), National Institutes of Health Stroke Scale (NIHSS), and bilateral N20 amplitude and latency of somatosensory-evoked potential (SEP), while consciousness status classification and Judson classification were recorded. ResultsOne case in the control group and two in the observation group dropped out. Significant time main effects and interaction effects were observed in CRS-R score (F = 118.420, P < 0.001; F = 23.980, P < 0.001, respectively) and NIHSS score (F = 103.376, P < 0.001; F = 14.241, P < 0.001, respectively). Significant group main effects, time main effects and interaction effects were observed in N20 amplitude (F > 4.303, P < 0.05) and N20 latency (F > 7.569, P < 0.05). Simple effects analysis showed CRS-R score, N20 amplitude, NIHSS score and N20 latency were better in the observation group than in the control group (P < 0.05) after the intervention, while the consciousness status classification and Judson classification were also better (|Z| > 2.160, P < 0.05). ConclusionrTMS can further promote recovery of consciousness, improve neurological function, and enhance the integrity of central conduction pathways in patients with pDoC after stroke.

Implementation Science is an interdisciplinary field dedicated to systematically studying how to effectively translate evidence-based research findings into practical application and implementation. In the health-related context, it focuses on enhancing the efficiency and quality of healthcare services, thereby facilitating the transition from scientific evidence to real-world practice. This article elaborates on Theories, Models, and Frameworks (TMF) within health-related Implementation Science, clarifying their basic concepts and classifications, and discussing their roles in guiding implementation processes. Furthermore, it reviews and prospects current research from three aspects: the constituent elements of TMF, their practical applications, and future directions. Five representative frameworks are emphasized, including the Consolidated Framework for Implementation Research (CFIR), the Practical Robust Implementation and Sustainability Model (PRISM), the Exploration, Preparation, Implementation, Sustainment (EPIS)framework, the Behavior Change Wheel (BCW), and the Normalization Process Theory (NPT). Additionally, resources such as the Dissemination & Implementation Models Webtool and the T-CaST tool are introduced to assist researchers in selecting appropriate TMFs based on project-specific needs.

Purpose To evaluate the effect of PCSK9 gene knockout on myocardial function in obese mice via ultrasound strain technology,and to discuss the related mechanisms.Materials and Methods Twenty six-week-old wild-type C57BL/6 male mice were selected and randomly divided into a normal group(n=10)and an obese group(n=10).Additionally,ten six-week-old PCSK9-/-C57BL/6 male mice were selected as the PCSK9-/-group.Mice in the obese group and PCSK9-/-group were fed with high-fat feed to create models,while those in the normal group were fed with regular feed.After 12 weeks,mice that were successfully modeled were selected from the obese group and PCSK9-/-group.Then,the three groups of mice were subjected to cardiac ultrasound,transmission electron microscopy and immunofluorescence staining to observe relevant indicators.Results The interventricular septal end-diastolic thickness of mice in obese group,normal group,and PCSK9-/-group were(0.98±0.13)mm,(0.77±0.07)mm,(0.78±0.13)mm,respectively,with statistically significant difference(F=5.10,P=0.02).The obese group was thicker than the normal group(t=2.73,P＜0.05),while the PCSK9-/-group was thinner than the obese group(t=-2.92,P＜0.05).There were statistically significant differences in global longitudinal strain and global circumferential strain of the left ventricle among the three groups(F=7.44,15.40,P＜0.05),with the obese group showing a decrease in global longitudinal strain and global circumferential strain compared to the normal group(t=3.79,5.50,P＜0.05).The PCSK9-/-group showed an increase in global longitudinal strain and global circumferential strain compared to the obese group(t=-2.53,-3.37,P＜0.05).Electron microscopy and immunofluorescence results showed that the myocardial ultrastructure of the obese group was damaged,and the expression of NLRP3 and Caspase-1 were higher than that of the normal group(t=12.53,-4.73,P＜0.05),the myocardial ultrastructure damage in the PCSK9-/-group was significantly improved,the expression of NLRP3 and Caspase-1 were lower than that in the obese group(t=-6.23,2.05,P＜0.05).Conclusion Ultrasound strain can more sensitively detect changes in myocardial function in obese mice with PCSK9 gene knockout compared with conventional cardiac ultrasound parameters.Knockout of the PCSK9 gene may improve myocardial function in obese mice by inhibiting the expression of NLRP3 and Caspase-1.

It was a single-center cross-sectional study to investigate the association of serum C3 level with blood pressure and estimated glomerular filtration rate (eGFR) in patients with idiopathic membranous nephropathy (IMN). The clinical and pathological data of 98 patients with IMN diagnosed by renal biopsy in the Department of Nephrology of East Hospital Affiliated to Tongji University from August 1, 2018 to October 31, 2023 were retrospectively analyzed. The demographic characteristics, serum complement C3 and other clinical data were compared between the non-hypertension group ( n=37) and hypertension group ( n=61). Pearson or Spearman correlation analysis method was used to analyze the correlation between serum C3 and eGFR in IMN patients and IMN patients with hypertension. Multiple linear regression analysis was used to analyze the related factors of eGFR in IMN patients with chronic kidney disease stage 1-3 in hypertension group. The results showed that compared with the non-hypertension group, the patients in hypertension group were older, and had higher levels of serum creatinine, cystatin C, urinary microalbumin to creatinine ratio, serum C3 and C4, and lower eGFR (all P<0.05). The correlation analysis showed that there was no correlation between serum C3 level and eGFR in IMN patients ( r=0.118, P=0.247). However, serum C3 level was positively correlated with eGFR in IMN patients with hypertension ( r=0.325, P=0.011). Multiple linear regression analysis showed that eGFR was negatively correlated with age ( β=-0.328, P=0.013), and positively correlated with serum C3 level ( β=0.228, P=0.048). The study shows that serum C3 level in hypertension group is higher than that in non-hypertension group in IMN patients. Moreover, serum C3 is positively correlated with eGFR.
