BACKGROUND:In recent years,brain-computer interface technology has shown significant promise for rehabilitating limb dysfunction in stroke patients.With ongoing research deepening and its broader clinical application,combining brain-computer interface with other rehabilitation therapies to improve limb function has become a focal point of study.OBJECTIVE:To analyze and summarize the efficacy of brain-computer interface combined with various therapies in treating limb dysfunction in stroke patients and to explore the clinical value of these combined strategies.METHODS:The search terms used for the literature review in Chinese databases were"brain-computer interface,BCI,stroke,"while the terms"brain-computer interface,BCI,brain-computer interaction,brain-machine interface,BMI,stroke"were used for English databases.Literature searches were conducted in CNKI,WanFang,VIP,PubMed,Embase,and Web of Science,from the time of database construction to September 2024.Finally,a total of 3 054 articles were retrieved,and 75 articles were included after screening for summarization.RESULTS AND CONCLUSION:Currently,brain-computer interfaces,used alone or in combination with other treatments such as Chinese medical treatment,conventional rehabilitation therapy,or physical factor therapy,are achieving better outcomes in treating limb dysfunction in stroke patients.However,the efficacy of brain-computer interfaces combined with transcranial direct current stimulation for treating upper and lower limb dysfunctions is still debated.Researchers are increasingly recognizing the feasibility of these combined therapies.Yet,challenges such as limited exploration of therapeutic mechanisms,absence of standardized protocols,and small sample sizes hinder their broad application.Future research should therefore focus on understanding the mechanisms by which brain-computer interfaces can enhance effects when combined with other therapies and on standardizing criteria for clinical trials to enable widespread clinical adoption.

Multiple endocrine neoplasia(MEN) is a rare autosomal dominant genetic disorder characterized by hyperplasia or tumor development in two or more endocrine glands. Currently, MEN is classified into four subtypes: MEN1, MEN2, MEN3, and MEN4. Among these, MEN4 is caused by mutations in the CDKN1B gene and presents clinical manifestations similar to MEN1, though the age of onset and disease progression differ. Due to its rarity, this article reviews the pathogenesis and treatment strategies for MEN4, aiming to provide valuable insights for its diagnosis and management.

Gastric cancer with hemorrhage and cerebral infarction is a serious complica-tion with poor prognosis in clinic. Although the incidence rate is extremely low, the fatality and disability rates are very high. In addition, the opposition in treatment between the two complica-tions increases the difficulty of clinical diagnosis and treatment. The authors report the diagnosis and treatment of a gastric cancer patient with hemorrhage and new cerebral infarction, in order to to provide reference for related treatments.

Objective:To compare the efficacy of forceful reduction percutaneous pedicle screw and ordinary percutaneous pedicle screw in the treatment of osteoporotic thoracolumbar burst fracture with kyphosis.Methods:A retrospective cohort study was conducted to analyze the clinical data of 566 patients with osteoporotic thoracolumbar burst fracture with kyphosis admitted to Honghui Hospital, Xi ′an Jiaotong University from January 2015 to December 2018, including 191 males and 375 females, with age range of 48-79 years [(61.7±10.7)years]. Fracture segments were located at T 11 in 134 patients, T 12 in 154, L 1 in 160, and L 2 in 118. All fractures were type IIIA according to the acute symptomatic osteoporotic thoracolumbar fracture classification (ASOTLF). The thoracolumbar osteoporotic fracture severity score assessment system (TLOFSAS) score was ≥5 points. A total of 275 patients underwent forceful reduction and percutaneous pedicle screw internal fixation (forceful reduction screw group), and 291 patients underwent common percutaneous pedicle screw internal fixation (common screw group). The operation time, intraoperative blood loss, times of X-ray exposure on patients and measures documented before operation, at 3 days after operation and at 2 years after operation including anterior height ratio of the injured vertebrae, sagittal Cobb angle of the injured vertebrae, Japanese Orthopaedic Association (JOA) score and visual analog scale (VAS) were compared between the two groups. Moreover, degree of correction of Cobb angle at 3 days after operation, loss of correction of Cobb angle at 2 years after operation and postoperative complications were observed. Results:All patients were followed up for 25-34 months [(29.9±3.4)months]. The operation time, intraoperative blood loss and times of X-ray exposure on patients in forceful reduction screw group were (69.4±10.2)minutes, (60.3±13.1)ml and (26.8±3.7)times, less than (80.6±11.9)minutes, (80.7±15.4)ml and (30.4±3.4)times in common screw group (all P<0.01). There was no significant difference in anterior height ratio of the injured vertebrae between the two groups before operation and at 3 days after operation (all P>0.05). The anterior height ratio of the injured vertebrae in forceful reduction screw group was (95.5±2.3)% at 2 years after operation, significantly higher than (85.4±1.7)% in common screw group ( P<0.01). There was no significant difference in sagittal Cobb angle of the injured vertebrae between the two groups before operation ( P>0.05). The sagittal Cobb of the injured vertebrae in forceful reduction screw group at 3 days and 2 years after operation were (7.9±1.6)° and (8.8±1.5)°, lower than (10.6±1.1)° and (12.3±1.2)° in common screw group ( P<0.05 or 0.01). There were no significant difference in JOA score and VAS between the two groups before operation, at 3 days and at 2 years after operation (all P>0.05). The degree of correction of Cobb angle in forceful reduction screw group was (19.4±2.5)°, higher than (17.3±2.6)° in common screw group ( P<0.05). The loss of correction of Cobb angle in forceful reduction group was less than that in common screw group at 2 years after operation, but the difference was not statistically significant ( P>0.05). The incidence of postoperative complications in forceful reduction screw group was 12.4% (34/275), compared to 14.1% (41/291) in common screw group ( P>0.05). There were no complications such as iatrogenic nerve injury, fracture or loosening of internal fixator or leakage of bone cement in the spinal canal in both groups. Conclusions:For osteoporotic thoracolumbar burst fracture with kyphosis, forceful reduction and percutaneous pedicle screw internal fixation can significantly shorten operation time, reduce intraoperative blood loss and times of X-ray exposure on patients, restore height of the injured vertebrae, correct kyphosis and maintain reduction height of the injured vertebrae in contrast with conventional percutaneous pedicle screw internal fixation.
