ObjectiveTo systematically evaluate the rehabilitation effect of blood flow restriction training (BFRT) as an adjunctive rehabilitation intervention on lower-limb motor function, balance ability, walking endurance and activities of daily living in stroke patients. MethodsRandomized controlled trials (RCT) on BFRT combined with rehabilitation training for stroke patients published from database inception to January 31, 2026 were retrieved from CNKI, Wanfang data, PubMed, Embase, Cochrane Library and Web of Science. Two researchers independently conducted literature screening, data extraction and bias risk assessment based on the PICO principle. Meta-analysis, subgroup analysis and sensitivity analysis were performed using RevMan 5.4.1 and Stata 17.0. ResultsA total of 15 RCT were included, involving 712 stroke patients including 354 in the control group and 358 in the experimental group. Compared with rehabilitation training, combination of BFRT significantly improved Fugl-Meyer Assessment-Lower Extremities scores (MD = 1.77, 95%CI 0.02 to 3.52, P = 0.047), Berg Balance Scale scores (MD = 5.39, 95%CI 2.20 to 8.59, P < 0.001) and 6-Minute Walk Test distance (MD = 10.24, 95%CI 7.76 to 12.72, P < 0.001). There was no significant difference in modified Barthel Index scores and Timed Up and Go Test results between two groups (P > 0.05). Subgroup analysis indicated that the intervention protocol with a duration of more than four weeks and BFRT combined with resistance training achieved better rehabilitation effect. ConclusionAs an adjunctive rehabilitation method, BFRT can significantly improve lower-limb motor function, balance and walking endurance of stroke patients, while its effect on activities of daily living and functional mobility remains unclear. The protocol of BFRT combined with resistance training for more than four weeks is preferentially recommended, which is more suitable for chronic stroke patients with stable condition, basic walking ability and no cognitive impairment.

Abstract Ferroptosis , a novel , non-apoptotic form of cell death discovered in 2012 , has garnered significant at- tention. It is implicated in the pathogenesis and progression of various intestinal diseases , including colorectal canc- er, intestinal ischemia-reperfusion injury , functional gastrointestinal disorders , and inflammatory bowel disease. These processes involve multiple pathological mechanisms such as inflammation , immune dysregulation , and intesti- nal epithelial dysfunction. By reviewing and summarizing recent literature on ferroptosis-related mechanisms in in- testinal diseases , this article explores the roles and effects of ferroptosis in different intestinal pathologies.

The reconstruction of the temporomandibular joint presents a multifaceted clinical challenge in the realm of head and neck surgery, underscored by its relatively infrequent occurrence and the lack of comprehensive clinical guidelines. This review aims to elucidate the available approaches for TMJ reconstruction, with a particular emphasis on recent groundbreaking advancements. The current spectrum of TMJ reconstruction integrates diverse surgical techniques, such as costochondral grafting, coronoid process grafting, revascularized fibula transfer, transport distraction osteogenesis, and alloplastic TMJ replacement. Despite the available options, a singular, universally accepted 'gold standard' for reconstructive techniques or materials remains elusive in this field. Our review comprehensively summarizes the current available methods of TMJ reconstruction, focusing on both autologous and alloplastic prostheses. It delves into the differences of each surgical technique and outlines the implications of recent technological advances, such as 3D printing, which hold the promise of enhancing surgical precision and patient outcomes. This evolutionary progress aims not only to improve the immediate results of reconstruction but also to ensure the long-term health and functionality of the TMJ, thereby improving the quality of life for patients with end-stage TMJ disorders.

PURPOSE: Postpancreatectomy hemorrhage (PPH) is a life-threatening complication after pancreatoduodenectomy. Stent-graft implantation is an emerging treatment option for PPH. This study reports the outcome of PPH treated with stent-graft implantation. METHODS: This was a single-center, retrospective study. Between April 2020 and December 2023, 1723 pancreatectomy cases were collected while we screened 12 cases of PPH after pancreatoduodenectomy treated with stent-graft implantation. Patients' medical and radiologic images were retrospectively reviewed. Technical and clinical success, complications, and stent-graft patency were evaluated. Continuous data are reported as means ± standard deviation when normally distributed or as median (Q₁, Q₃) when the data is non-normal distributed. Categorical data are reported as n (%). A p < 0.05 was considered statistically significant. Kaplan-Meier estimates were used for stent patency and patients' survival. RESULTS: Pancreatic fistula was identified in 6 cases (50.0%), and pseudoaneurysm was identified in 3 cases (25.0%), including pancreatic fistula together with pseudoaneurysm in 1 case (8.3%). All pseudoaneurysm or contrast extravasation sites were successfully excluded with patent distal perfusion, thus technical success was achieved in all cases. The overall survival rate at 6 months and 1 year was 91.7% and 78.6%, respectively. One patient had herniation of the small intestine into the thoracic cavity, which caused a broad thoracic and abdominal infection and died during hospitalization. Rebleeding occurred at the gastroduodenal artery stump in 1 case after stent-graft implantation for the splenic artery and was successfully treated with another stent-graft implantation. Two cases of asymptomatic stent-graft occlusion were observed at 24.6 and 26.3 after the operation, respectively. CONCLUSIONS With suitable anatomy, covered stent-graft implantation is an effective and safe treatment option for PPH with various bleeding sites and causes.

Objective To explore changes of serum levels of tumor necrosis factor alpha(TNF-α),interleukin-10(IL-10),and Helicobacter pylori(HP)positivity rate in patients with early gastric cancer,and the diagnostic value of three factors in early gastric cancer.Methods A total of 312 patients with gastric discomfort were included in this study and used as the observation subjects.Patients were divided into the gastritis group(n=100),the precancerous lesion group(n=110)and the early gastric cancer group(n=102)based on their gastroscopy.Enzyme linked immunosorbent assay(ELISA)was used to detect serum levels of TNF-α and IL-10.HP infection was detected in the three groups.Multivariate Logistic regression was used to analyze influencing factors of early gastric cancer.Receiver operating characteristic(ROC)curve analysis was used to evaluate the diagnostic value of serum TNF-α,IL-10 and HP infection in early gastric cancer.Results The levels of TNF-α,IL-10 and HP positivity rate were increased in the gastritis group,the precancerous lesion group and the early gastric cancer group in sequence(all P＜0.05).Hot food,heavy salt,pepsinogen Ⅱ(PG Ⅱ),HP positivity and elevated levels of TNF-α and IL-10 were independent risk factors for early gastric cancer,while elevated PGⅠ was a protective factor(all P＜0.05).The areas under the curve for serum TNF-α,IL-10,HP infection and their combined diagnosis of early gastric cancer were 0.694,0.698,0.763,and 0.870,respectively.The combined diagnostic efficacy of the three was better than that of individual diagnosis(all P＜0.05).Conclusion The serum levels of TNF-α,IL-10 and HP positivity rate are significantly increased in patients with early gastric cancer,and all three have certain diagnostic value for early gastric cancer.
