Objective:To retrieve, screen, and synthesize the best available evidence related to perioperative blood glucose management in patients undergoing bariatric and metabolic surgery.Methods:Relevantliterature on perioperative blood glucose management in bariatric and metabolic surgery patients was retrieved from Chinese and English databases using a top-down strategy based on the "6S" evidence-based model. The search period was from database inception to June 30, 2024. Two evidence-based trained researchers independently screened the literature according to inclusion criteria, assessed methodological quality, and extracted and synthesized the evidence.Results:Fourteen articles were eventually included, comprising five clinical practice guidelines, four expert consensus, two systematic reviews, one evidence summary, and two randomized controlled trials. Eighteen pieces of best evidence were synthesized across seven dimensions: principles of glycemic management, target blood glucose levels, management of hypoglycemic agents, very-low-calorie diet intervention, treatment of postoperative hypoglycemia treatment, self-monitoring of blood glucose, and follow-up and guidance.Conclusions:The best evidence extracted in this study is scientifically sound and clinically applicable, providing evidence-based support and decision-making guidance for perioperative blood glucose management in patients undergoing bariatric and metabolic surgery. However, clinical practitioners need to apply it selectively in the context of hospital and departmental realities when applying it in practice.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

OBJECTIVES: To analyze the efficacy and safety of concomitant left atrial appendage clipping during heart valve surgery for valvular heart disease patients with atrial fibrillation. METHODS: Fifty-eight patients who underwent concomitant left atrial appendage clipping during cardiac valve surgery in the Second Affiliated Hospital of Nanchang University from January 2017 to June 2023 were included in the analysis, including 1 case who underwent aortic valve replacement, 49 cases who underwent mitral valve replace-ment (or valvuloplasty)+tricuspid valvuloplasty, and 8 cases who underwent double valve replacement+tricuspid valvuloplasty (3 cases combined with coronary artery bypass grafting). The patients were followed up for 3-36 months [(16.69±6.61) months] after operation, and the changes of cardiac function and the occurrence of serious adverse complications were evaluated. RESULTS: The cardiopulmonary bypass time ranged from 75 to 145 min [(102.50±21.03) min], and the aortic cross-clamp time ranged from 35 to 80 min [(58.02±14.63) min]. The length of postoperative intensive care unit stay was 1 to 5 days [(2.47±0.82) d], and the length of postoperative hospital stay was 7 to 22 days [(10.84±2.69) d]. Cardiac ultrasound indicated complete closure of the left atrial appendage in all cases. During the follow-up, New York Heart Association (NYHA) functional classifications were improved in 54 patients. No left atrial appendage-related bleeding events or other perioperative complications were observed; and no cerebral infarction, limb embolism events, or mortality cases occurred during the follow-up. CONCLUSIONS For valvular heart disease patients with atrial fibrillation, concomitant left atrial appendage clipping during cardiac valve surgery demonstrates efficacy and safety, with no severe adverse events during a medium-term follow-up.

N6-Methyladenosine (m6A) modification is a crucial post-transcriptional regulatory mechanism and the most abundant and highly conserved RNA epigenetic modification in eukaryotes. Previous studies have indicated the involvement of m6A modification in various tissue regeneration processes, including liver regeneration. Vir-like m6A methyltransferase associated protein (VIRMA) is an m6A methyltransferase with robust methylation capability. However, its role in liver regeneration remains poorly understood. In this study, we generated liver-specific Virma knockout mice using the Cre-loxP system and investigated the biological functions of VIRMA in liver regeneration using both the Associating Liver Partition and Portal vein Ligation for Staged Hepatectomy (ALPPS) mouse model and the carbon tetrachloride (CCl₄) mouse model. The expression level of VIRMA was rapidly up-regulated after ALPPS surgery and gradually down-regulated during liver repair. Virma deficiency significantly impaired liver regeneration capacity and disrupted cell cycle progression. Methylated RNA immunoprecipitation sequencing (MeRIP-seq) analysis revealed that Shq1 is an effective downstream target of VIRMA-mediated m6A modification. The upregulation of Shq1 enhanced the proliferation ability of cells, which was attenuated by the specific AKT inhibitor ipatasertib. Supplementation of Shq1 in vivo alleviated the liver cell proliferation inhibition caused by Virma deficiency. Furthermore, the m6A-binding protein heterogeneous nuclear ribonucleoprotein a2b1 (HNRNPA2B1) enhanced the mRNA stability of Shq1. Mechanistically, Virma deficiency resulted in decreased m6A modification on Shq1 mRNA, leading to reduced binding ability of m6A-binding protein HNRNPA2B1 with Shq1, thereby decreasing the mRNA stability of Shq1 and reducing its protein expression level. Downregulation of Shq1 inhibited the PI3K/AKT pathway, thereby suppressing cell proliferation and cell cycle progression, ultimately impeding liver regeneration. In summary, our results demonstrate that VIRMA plays a critical role in promoting liver regeneration by regulating m6A modification, providing valuable insights into the epigenetic regulation during liver regeneration.

Objective:To analyze the association of physical activity (PA) levels with the cognitive function and mental health among health check-up population.Methods:It is a cross-sectional study. The data from 869 health check-up population were consecutively collected from Beijing Tiantan Hospital, Capital Medical University between January 1, 2023 and December 31, 2023, including sex, age, body mass index (BMI), waist to hip ratio (WHR), educational years, medical history and personal history. The Global Physical Activity Questionnaire (GPAQ) was used to evaluate the PA levels, the Montreal Cognitive Assessment (MoCA) was performed to assess the global cognitive function, and the Patient Health Questionnaire 9 (PHQ-9) and the 7-item Generalized Anxiety Disorder (GAD-7) was used to screen for depression and generalized anxiety, respectively. Laboratory examination of lipid metabolism-related biomarkers included total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), lipoprotein(a) [Lp(a)], apolipoprotein A-1 (ApoA1), apolipoprotein B (ApoB), small dense low-density lipoprotein (sdLDL) and remnant cholesterol (RC). The differences in general data, scale evaluation, and lipid metabolism-related biomarkers were compared among three groups [sufficiently active group:≥600 (metabolic equivalent,MET)-min/week, insufficiently active group: 1-599 MET-min/week, and inactive group: 0 MET-min/week]. The multiple linear regression was used to analyze the correlation between the PA or sitting time and MoCA, PHQ-9 or GAD-7 scores, respectively.Results:A total of 869 health check-up population was finally included, with the age of (51.22±10.09) years old; among these, 545 patients were men (62.72%), 324 cases were women (37.28%), 153 cases with cognitive impairment (17.61%). Participants in sufficiently active group had lower WHR [(0.88±0.07) vs (0.89±0.07)], sitting time [7.00 (4.00, 10.00) vs 10.00 (6.00, 12.00) h], PHQ-9 [2.00 (0, 5.00) vs 3.00 (0, 7.00) scores], GAD-7 [2.00 (0, 4.00) vs 3.00 (0, 6.00) scores], and sdLDL levels [0.93 (0.60, 1.32) vs 1.09 (0.70, 1.45) mmol/L] than those in inactive group (all corrected P<0.05). Population in sufficiently active group was older than those in insufficiently active group[(52.10±9.90) vs (49.88±9.88) years], and had lower BMI [(25.73±3.82) vs (26.13±3.54) kg/m 2], WHR [(0.88±0.07) vs (0.90±0.07)], proportion in medical history of alcohol consumption (14.46% vs 23.61%), sitting time [7.00 (4.00, 10.00) vs 9.15 (6.00, 12.00) h], PHQ-9 [2.00 (0, 5.00) vs 3.00 (0, 5.00) scores], and GAD-7 [2.00 (0, 4.00) vs 2.00 (0, 5.00) scores] than those in insufficiently active group (all corrected P<0.05). The sitting time ( β=-0.081, 95% CI:-0.134, -0.028), age ( β=-0.089, 95% CI:-0.111, -0.067), and WHR ( β=-7.069, 95% CI:-11.667, -2.472) were negatively correlated with the MoCA scores; the PA levels ( β=-1.06×10 -4, 95% CI:-1.06×10 -4, -3.05×10 -5), age ( β=-0.077, 95% CI:-0.106, -0.049), BMI ( β=-0.098,95% CI:-0.192, -0.005), educational years ( β=-0.090, 95% CI:-0.151, -0.029), and HDL-C levels ( β=-4.236, 95% CI:-6.171, -2.301) were negatively correlated with the elevation of PHQ-9 scores, while the PA ( β=-9.14×10 -6, 95% CI:-6.76×10 -6, 8.58×10 -5), age ( β=-0.089, 95% CI:-0.118, -0.060), and HDL-C levels ( β=-3.442, 95% CI:-5.403, -1.480) were negatively correlated with the of GAD-7 scores (all P<0.05). Conclusion:Decreased physical activity level significantly increases the risk of depression, anxiety, and cognitive impairment among health check-up population, suggesting that early screen for physical activity and active intervention for exercise and sedentary behavior are of great significance for preventing cognitive decline, anxiety and depression.

Objective:To analyze the mediating effect of the inflammation on the sex differences in cognitive function among middle-aged and elderly individuals receiving health checkups.Methods:This cross-sectional study consecutively collected data from 757 middle-aged and elderly individuals receiving health checkups at Beijing Tiantan Hospital, Capital Medical University between January 1, 2023 and December 31, 2023. The gender, age, body mass index (BMI), waist to hip ratio (WHR), educational years, medical history and personal history were collected. The Montreal Cognitive Assessment (MoCA) were performed to assess the cognitive function. Inflammation indicators included the single blood inflammatory markers [white blood cell (WBC), high sensitivity C-reactive protein (hs-CRP), interleukin (IL)-6, and erythrocyte sedimentation rate (ESR)], inflammatory markers derived from blood cell counts, including neutrophil-lymphocyte ratio (NLR), derived neutrophil-lymphocyte ratio (dNLR), monocyte-to-lymphocyte ratio (MLR), neutrophil-monocyte to lymphocyte ratio (NMLR), systemic inflammatory response index (SIRI), systemic immune-inflammation index (SII), and aggregate index of systemic inflammation (AISI); and inflammatory markers derived from blood cell counts and high-density lipoprotein cholesterol (HDL-C), including neutrophil to HDL-C ratio (NHR), monocyte to HDL-C ratio (MHR), lymphocyte to HDL-C ratio (LHR), and platelet to HDL-C ratio (PHR) were all recorded. The simple mediation effect model in the SPSS 29.0 PROCESS macro was used to analyze the mediation effects of the inflammation indicators on the gender differences in cognitive function among middle-aged and elderly individuals receiving health checkups.Results:Among the 757 health checkup population in the final analysis, 466 were male (61.56%), and 291 were female (38.44%), with a mean age of (54.24±8.42) years. The male had higher BMI, WHR, educational years, frequency of hypertension and diabetes mellitus, MoCA scores, and inflammation indicators, including hs-CRP, WBC, NLR, MLR, NMLR, SIRI, AISI, NHR, MHR, LHR and PHR than those in the female [(26.41±3.20) vs (24.32±3.06) kg/m 2, (0.93±0.05) vs (0.83±0.06), 12 (9, 16) vs 11 (8, 15) years, 37.77% vs 21.31%, 16.52% vs 8.93%, 26 (24, 28) vs 26 (22, 28) points, 0.81 (0.38, 1.61) vs 0.63 (0.27, 1.63) mg/L, 5.75 (4.96, 6.78) vs 5.08 (4.27, 6.05)×10 9/L, 2.06 (1.67, 2.64) vs 1.87 (1.50, 2.37), 0.21 (0.17, 0.25) vs 0.17 (0.13, 0.21), 2.26 (1.84, 2.88) vs 2.02 (1.68, 2.55), 0.71 (0.51, 1.01) vs 0.49 (0.35, 0.67), 153.43 (108.91, 220.63) vs 113.34 (78.06, 164.27), 0.16 (0.12, 0.20) vs 0.11 (0.08, 0.14), 0.02 (0.01, 0.02) vs 0.01 (0.01, 0.01), 0.08 (0.06, 0.01) vs 0.06 (0.04, 0.07), 9.33 (7.82, 11.33) vs 8.36 (6.37, 10.21)] (all P<0.05). ESR and dNLR levels in the male were both lower than those in the female [6 (2, 11) vs 11 (6, 18) mm/h, 0.87 (0.85, 0.89) vs 0.89 (0.87, 0.91)] (both P<0.05). The MoCA score was negatively correlated with age, WHR, hs-CRP, IL-6, NLR, dNLR, NMLR, SIRI, NHR ( r=-0.355, -0.103, -0.115, -0.085, -0.094, -0.078, -0.093, -0.074, -0.108), and positively correlated with educational years ( r=0.512) (all P<0.05). After adjustment for confounding factors, including age, BMI, WHR, educational years, hypertension, and diabetes mellitus, dNLR and NHR mediated 13.11% and 12.80% association between gender and MoCA scores, respectively; after adjustment for above-mentioned confounders adding hs-CRP and IL-6, dNLR mediated 13.07% association between gender and MoCA score (all P<0.05), whereas no significant mediating effect was found of NHR on this association. Conclusions:Inflammation performed potential mediating effect on the association between sex difference and cognitive function among middle-to-old aged health checkup population, and the sex difference in cognitive function was partly mediated by the dNLR and NHR.
