The deficiency of fingers due to various reasons leads to a certain degree of loss of full or part hand functions. Physical and mental health of patients are seriously affected, and patients have varying degrees of reduced quality of life. Prosthesis fingers play an important role in completing the body shape and enhancing patients’ self-confidence and self-esteem. However, how to make prosthesis fingers perform coordinated movements and restore complete functions is a crucial problem that urgently needs to be solved. This paper reviews the methods of brain-computer interface controlled fine finger movements and elaborates on the origin, current situation, and advancements of the development of this technology, laying a foundation for subsequent research, with the expectation of helping patients solve the problems arising from the insufficiency or absence of finger functions.

Objective: To analyze the features of unhealthy lifestyle patterns among primary and secondary school students in the nutrition improvement program for rural compulsory education students (NIPRCES) areas in China in 2021 and 2023, so as to provide data support for lifestyle promotion and healthy development among primary and secondary school students. Methods: Adopting a cluster random sampling method, data on primary and secondary students aged 7-15 years from nutrition and health surveillance of China NIPRCES in 2021 and 2023 were collected. The prevalence of unhealthy lifestyles among primary and secondary students such as physical inactivity, outdoor inactivity, excessive screen time, and sleep deprivation by gender, school section, urban/rural, and region were analyzed. The reporting rates of the above indicators among primary and secondary students were compared by Chi-square test. Results: In 2021 and 2023, the rates of moderate to vigorous physical inactivity among primary and secondary school students were 79.2% and 80.4%, the rates of outdoor inactivity were 42.8% and 49.3%, the rates of excessive video time were 2.6% and 2.9%, the rates of sleep deprivation were 32.9% and 22.6%, and the differences were statistically significant( χ 2=51.86,1 071.48,18.36,3 296.99, P <0.05). In 2023, the rate of outdoor inactivity for primary and secondary students increased by 6.5 percentage points compared with 2021, and the rate of sleep deprivation decreased by 10.3 percentage points compared with that in 2021. In 2021 and 2023, the reporting rates of moderate to vigorous physical inactivity, outdoor inactivity, and sleep deprivation among girls and junior high school students were higher than those among boys ( χ 2=174.41,180.11; 175.75, 85.46 ;92.22,151.35) and elementary school students ( χ 2=136.64,5.75; 40.55,4.71;162.80,3 291.61); the reporting rates of moderate to vigorous physical inactivity( χ 2=194.43,118.60) and sleep deprivation ( χ 2=969.66,983.72) among urban students were higher than those among rural students; the reporting rates of excessive video time for boys and junior high school students were higher than those for girls ( χ 2=103.62,84.85) and elementary school students ( χ 2=810.09,626.51)( P <0.05). From a regional distribution perspective, the reporting rates of moderato to vigorous physical inactivity, outdoor inactivity, and excessive video time among primary and seconday school students in the central and western regions were lower than those in the eastern region ( χ 2= 663.44,302.78; 356.97,82.10;50.89,81.83) ( P <0.05). Conclusions Unhealthy lifestyles remain prevalent among primary and secondary students in NIPRCES areas of China. These findings underscore the need to strengthen policy implementation for promoting healthy lifestyles among primary and secondary school students.

Objective: To understand the prevalence of elevated blood pressure and its association with dietary patterns in children and adolescents in China, providing evidence for developing dietary intervention of hypertension in children and adolescents. Methods: Data were derived from the China Children s Nutrition and Health System Survey and Application Project(2019-2021). A stratified cluster random sampling method was used to include 7 933 participants from 28 survey sites in seven major regions of Northeast, North, Northwest, East, Central, South and Southwest China. Multivariate Logistic regression models were used to analyze associations between demographic characteristics, nutritional status and elevated blood pressure. Exploratory factor analysis identified dietary patterns, which were divided into three quartile groups (T3, T2, T1) based on factor scores (compliance for dietary pattern) from high to low, and multivariate Logistic regression model assessed the correlation between elevated blood pressure and dietary patterns. Results: The prevalence of elevated blood pressure was 15.4% among Chinese children aged 7-17 years. Significant differences were observed across nutritional status (reference: underweight; normal weight: OR =1.57; overweight: OR = 2.61 ; obesity: OR =3.85), urban/rural residence (reference: rural; urban: OR =0.86), and paternal education (reference: junior high school and below; bachelor degree or above: OR =0.68) ( P <0.05). The detection rates of high blood pressure in T3 group children and adolescents with four dietary patterns (staple food, animal based food, snacks, vegetables and fruits) were 15.7%, 14.6%, 16.8%, and 15.8%, respectively. After adjusting for residence, paternal education, and nutritional status, the "snack dietary pattern" (mainly candy, sugar sweetened beverages, and processed snacks) showed positive associations with elevated blood pressure in T2 ( OR =1.21) and T3 ( OR =1.19) tertiles ( P <0.05). Conclusions The snack dietary pattern is a related factor for elevated blood pressure in children and adolescents. Restricting unhealthy snack intake may promote cardiovascular health.

Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. It has a high prevalence and poor prognosis. The application of antiarrhythmic drugs and even surgery cannot completely treat the disease, and there are many sequelae. AF can be classified into the category of "palpitation" in Chinese medicine according to its symptoms. Acupuncture has a significant effect on AF. The authors find that an important mechanism of acupuncture in AF treatment is to regulate the cardiac vagus nerve. Therefore, this article intends to review the distribution and function of vagus nerve in the heart, the application and the regulatroy effect for the treatment of AF.

Allergen-associated proteases, pollutants, viral and fungal pathogens disrupted epithelial barrier integrity and promoted airway epithelial release of alarmins.Epithelial-derived Alarmins include thymic stromal lymphopoietin (TSLP), interleukin 33 (IL-33), and interleukin 25 (IL-25), which acted on a variety of effector cells such as dendritic cells (DCs), T-lymphocytes, innate lymphocyte cells (ILC2), B-lymphocytes, eosinophils, mast cells, basophils, and macrophages. T-lymphocytes, innate lymphocyte cell type 2 (ILC2), B-lymphocytes, eosinophils, mast cells, basophils and macrophages are the effector cells. By affecting the physiological and biochemical functions of target cells, such as proliferation and differentiation, survival and recruitment, and material metabolism, the alarmins had activated the intrinsic and adaptive immunity, and played a key role in allergic diseases such as bronchial asthma, atopic dermatitis, allergic rhinitis, and urticaria. A variety of monoclonal antibodies targeting epithelial-derived alarm factors have been developed for the above allergic diseases, and some of these products are already put into clinical use. As epidemiological studies showed that skin allergy closely related to airway allergy, allergic co-morbidities has imposed a heavy economic and psychological burden to patients. In-depth understanding the mechanism of alarmins will help to understand the developing and progression of allergic diseases, and develop more effective diagnostic and therapeutic strategies for allergic co-morbidities. This article reviews the mechanism and recent research advances of epithelial-derived alarmins in a variety of allergic diseases.

Objective:To evaluate corrective intra-articular osteotomy in the treatment of malreduced tibial pilon fractures in young patients.Methods:A retrospective study was conducted to analyze the 23 patients who had been treated for malreduced tibial pilon fractures by corrective intra-articular osteotomy from January 2013 to December 2022 at Department of Orthopedics, Orthopedic Research Institute, West China Hospital. They were 21 males and 2 females with a median age of 42.9(28.6, 48.1) years. The median interval between intra-articular osteotomy and initial injury or previous surgery was 97 (51, 166) d. The clinical efficacy was assessed by the ankle-hindfoot score of American Orthopaedic Foot and Ankle Society (AOFAS), MOS item short form health survey (SF-36), visual analog scale (VAS) pain score, ankle range of motion (ROM), modified Kellgren-Lawrence arthritis grading, and complications.Results:The median follow-up period was 35.4 (26.2, 72.2) months. At the last follow-up, the AOFAS ankle-hindfoot score, SF-36, VAS pain score, and ankle ROM for all patients were, respectively, (80.7±12.1) points, (72.2±13.9) points, 2.0(0, 3.0) points and 23.0°(18.0°, 30.0°), and the modified Kellgren-Lawrence arthritis grading revealed stage Ⅱ in 17 cases, stage Ⅲ in 5 cases, and stage Ⅳ in 1 case. For the 12 patients with sufficient preoperative data, the AOFAS ankle-hindfoot score [(80.9±10.1) points], SF-36 [(72.9±12.0) points], VAS pain score [2.5 (0.5, 3.0) points], and ankle ROM (26.5°±7.9°) at the last follow-up were significantly better than the preoperative values [(42.2±16.0) points, (36.0±8.8) points, 6.0 (5.5, 6.5) points, and 21.3°±7.0°] (all P<0.05). One patient who experienced significant pain postoperatively planned to receive ankle fusion surgery. No patients experienced deep infection, fracture non-union, or failure of internal fixation. Conclusion:Corrective intra-articular osteotomy may be a viable alternative treatment of malreduced tibial pilon fractures in young patients, because it can effectively improve short-term clinical and radiographic outcomes.

Objective:To identify risk factors influencing clinical efficacy of endoscopic resection of small rectal neuroendocrine tumor (NETs).Methods:A retrospective analysis was conducted on patients with rectal NETs ≤10 mm who underwent endoscopic resection from 2013 to 2022. Patients were divided into the endoscopic submucosal dissection (ESD) group and the endoscopic mucosal resection with ligation (EMRL) group according to the treatment methods. After comparing the baseline data, propensity score matching was performed to compare the rates of R1 resection and adequacy of vertical margin distance.Results:A total of 186 patients were included in this study, with 139 receiving ESD and 47 receiving EMRL. The R1 resection rates were 12.2% (17/139) and 2.1% (1/47) in the ESD and EMRL group, respectively ( χ2=3.027, P=0.082). A significant difference in vertical margin adequacy was observed between the two groups [69.1% (96/139) VS 85.1% (40/47), χ2=4.598, P=0.032]. After propensity score matching, 46 pairs of cases were included, and there were no significant differences in the R1 resection rate [6.5% (3/46) VS 2.2% (1/46), χ2=0.261, P=0.609] and vertical margin adequacy [78.3% (36/46) VS 84.8% (39/46), χ2=0.649, P=0.420] between the two groups. Univariate and multivariate Logistic regression analyses revealed that operator experience and preoperative biopsy were independent risk factors for inadequate margin. Conclusion:Treatment method may not be the key factor affecting the distance of the vertical margin after endoscopic resection, but preoperative biopsy and operator experience have a significant impact on margins. Biopsy before endoscopic resection should be avoided, and less experienced doctors are recommended to use EMRL method for small NETs due to its ease of execution.

Objective:To explore the short-term clinical effects of deep cervical lymph node-venous anastomosis in the treatment of Alzheimer’s disease (AD).Methods:A prospective exploratory study was conducted on the treatment of AD patients using the cervical deep lymph node-venous anastomosis technique in Scar and Wound Treatment Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, from September to October 2024. The patients underwent high-frequency ultrasound to locate deep cervical lymph nodes and the external jugular vein. Under general anesthesia, bilateral deep cervical lymph node-venous anastomoses were performed. Indocyanine green (ICG) lymphography was conducted via subcutaneous injection behind the ear to visualize lymph nodes in levels Ⅱ and Ⅲ. After making a skin incision along the posterior margin of the sternocleidomastoid muscle, the external jugular vein, internal jugular veins, and associated lymph nodes were exposed. Adjacent veins were selected for anastomosis of lymph node. Using microsurgical techniques, end-to-side or end-to-end anastomosis was completed for lymph nodes in levels Ⅱ and Ⅲ. Preoperative assessments included the mini-mental state examination (MMSE, a higher score indicates better cognitive function), Alzheimer’s disease assessment scale-cognitive subscale (ADAS-Cog, a higher score indicates greater impairment of cognitive function), Alzheimer’s disease cooperative study scale for activities of daily living (ADCS-ADL, a higher score indicates better ability to perform daily activity), and neuropsychiatric inventory (NPI, a higher score indicates more severe behavioral and emotional symptom). Postoperative follow-up included the same scales to observe changes in cognitive function, activities of daily living, and emotional communication.Results:Four patients (1 male, 3 females, aged 58-79 years) with AD were included. All were diagnosed based on cerebrospinal fluid biomarkers. All patients successfully underwent bilateral deep cervical lymph node-venous anastomoses. On average, 4.3 (2-7 per person) anastomoses were performed per patient. Surgical procedures lasted an average of 6.5 h (5.5-8.5 h) with minimal blood loss (less than 50 ml). Patients resumed normal activity within 6 hours postoperatively and were discharged after an average of 4.1 d (3.5-5.0 d). Postoperative complications included one case each of aspiration pneumonia, lower limb venous thrombosis, and transient delirium, all of whom resolved without long-term effects. Clinical symptoms, including memory decline, mood swings, and anxiety, showed varying degrees of improvement. Patients reported enhanced quality of life, emotional stability, and social engagement, confirming the procedure’s safety and potential cognitive benefits. At one month postoperatively, the MMSE scores of the four patients increased by an average of 0.8 points compared to preoperative levels. Additionally, the two patients who completed the ADAS-Cog assessments showed a decrease in their scores (reduced by 1.0 points and 11.3 points, respectively, compared to preoperative scores), indicating a certain degree of improvement in cognitive function during this period. The ADCS-ADL and NPI scores of four patients varied significantly, without showing any clear pattern.Conclusion:Lymphovenous anastomosis of the deep cervical lymph node-venous anastomosis may provide a new surgical intervention approach for AD, but further large-scale studies and long-term follow-up are needed to validate its safety and effectiveness.

Objective: To understand the prevalence and related factors of depressive symptoms among primary and secondary school students in the in depth monitoring counties of China s Rural Compulsory Education Nutrition Improvement Program, so as to provide a basis for prevention and psychological intervention of depressive symptoms among children and adolescents in rural areas. Methods: In November 2022, a stratified random sampling method was adopted to collect height and weight data, basic personal and family information of 7 949 primary and secondary school students from grade three to grade nine through physical measurements and questionnaires in 56 key monitoring schools implementing the Student Nutrition Improvement Program in 7 in depth monitoring counties (Jalaid Banner in Inner Mongolia, Jinzhai County in Anhui, Mao Xian in Sichuan, Tiandeng County in Guangxi, Mian County in Shaanxi, Zhaozhou County in Heilongjiang and Youxi County in Fujian), and to obtain the information related to their depressive symptoms through the self assessment questionnaire on depression. Multivariate Logistic regression analysis was conducted to analyze the prevalence of depressive symptoms among primary and secondary school students, as well as their related factors. Results: The detection rate of depressive symptoms among primary and secondary school students in the in depth monitored counties was 23.5%. Logistic regression analysis showed that the probability of detecting depressive symptoms was higher among female students, middle school students, students whose video screen duration per day was >2 h, and students whose parents marital status was divorced or widowed ( OR =1.40, 1.64, 1.60, 1.24), and students whose sleep duration reached the recommended standard, whose parents usually accompanied them daily for time was 60-<120 min and ≥120 min, and students whose mothers literacy level was middle school graduation had lower probability of detecting depressive symptoms ( OR =0.85, 0.84, 0.71, 0.76) ( P < 0.05 ). Conclusion The detection rate of depressive symptoms among students in the in depth monitoring area is high, and targeted interventions need to be developed for students to reduce the risk of mental health problems.
