ObjectiveColorectal cancer (CRC) is a highly heterogeneous malignancy, and traditional Chinese medicine (TCM) syndrome differentiation is widely used in its clinical management. However, the biological basis underlying different TCM syndromes remains insufficiently understood. This study aimed to investigate the proteomic differences between qi-blood deficiency syndrome (QBDS) and damp-heat syndrome (DHS) in CRC patients and to establish a “syndrome-differential protein-herbal component” network for exploring potential molecular mechanisms and therapeutic targets associated with syndrome-specific treatment strategies. MethodsTumor tissue samples were collected from 10 patients with pathologically confirmed CRC, including 5 patients diagnosed with QBDS and 5 with DHS according to standardized TCM syndrome differentiation criteria. Tandem mass tag (TMT)-based quantitative proteomics was employed to identify differentially expressed proteins (DEPs) between the two syndrome groups. Functional enrichment analyses, including Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses, were performed to characterize the biological functions and signaling pathways associated with the identified DEPs. Least absolute shrinkage and selection operator (LASSO) regression analysis was further applied to screen key syndrome-related proteins and construct a core protein prediction model. Subsequently, molecular docking was conducted to evaluate the binding affinities between representative herbal compounds, astragaloside IV and berberine, and the identified core proteins. Finally, cell counting kit-8 (CCK-8) assays were performed in HCT 116 and HT-29 colorectal cancer cell lines to validate the anti-proliferative activities of these compounds in vitro. ResultsA total of 44 DEPs were identified between QBDS and DHS tissues, including 21 upregulated and 23 downregulated proteins in the QBDS group relative to the DHS group. Functional enrichment analyses revealed that these proteins were primarily associated with antiviral immune responses, regulation of inflammatory signaling, NF‑κB signaling pathways, cholesterol metabolism, and other biological processes relevant to tumor progression and host immune regulation. LASSO regression analysis identified eight core proteins with potential syndrome-specific significance. Among them, ST7, GPCPD1, and PODXL were closely associated with QBDS, whereas FAT1, GRB7, KRT7, MAFF, and MMP8 were associated with DHS. Molecular docking demonstrated favorable interactions between astragaloside IV and QBDS-related proteins, with binding energies lower than -5 kcal/mol, indicating stable binding activity. Berberine exhibited even lower binding energies and stronger binding specificity toward DHS-related core proteins. In vitro experiments further confirmed that both compounds inhibited CRC cell proliferation, while berberine displayed significantly greater anti-proliferative efficacy. The lowest 48 h IC₅₀ value of berberine reached 15.21 mg/L in CRC cells, indicating a stronger growth-inhibitory effect than astragaloside IV. ConclusionCRC patients with QBDS and DHS exhibit distinct proteomic characteristics, suggesting that different TCM syndromes possess unique molecular signatures. The identified core proteins may serve as potential biomarkers for syndrome differentiation, while astragaloside IV and berberine may exert therapeutic effects through targeting syndrome-specific molecular networks. These findings provide preliminary proteomic evidence supporting syndrome-guided precision integrative medicine in CRC and offer new insights into the biological basis of TCM syndrome differentiation and individualized therapeutic strategies.

Laccase is a type of polyphenol oxidase that can catalyze the oxidation of various substances,including phenols,aromatic amines,and catecholamines.It has been widely utilized in pollutant degradation and analytical applications.However,the high cost of preparation of natural laccase and its susceptibility to environmental factors,which can lead to denaturation and inactivation,limit its practical applications.Nanozymes,which are nanomaterials that exhibit enzyme-like properties,offer advantages such as easy preparation,adjustable activity,and exceptional stability.Currently,many types of nanozymes have been developed.Inspired by the coordination of Cu2+with amino acids in the active site of natural laccase,researchers have employed coordination synthetic strategies to prepare laccase-like nanozymes.The metal nodes in these laccase-like nanozymes include copper,manganese,and cerium,while the ligands involve a variety of chemicals like nucleotides,amino acids,polypeptides,and aromatic acids.By manipulating factors such as the metal-to-ligand ratio,reducing capacity of ligands,buffer solutions,chloride ions,bromine ions,the catalytic activity of laccase-like nanozymes can be finely tuned.In this paper,laccase-like nanozymes developed through coordination strategies were categorized and summarized,along with review of their analytical applications in detection of phenolic compounds,disease biomarkers,antibiotics,pesticides,sulfur-containing pollutants,and time-temperature indicators.Furthermore,the challenges currently faced in the research of laccase-like nanozymes and future research directions were discussed.

Objective To investigate the relationship between serum microRNA(miRNA,miR)-9-5p,miR-21-5p and miR-206 and hemorrhagic transformation(HT)occurs and prognosis in patients with large ar-tery atherosclerotic cerebral infarction(ACI-LAA)after thrombolysis.Methods A total of 265 patients with ACI-LAA admitted to the hospital from April 2021 to November 2023 were selected as the research objects.According to whether HT occurred after intravenous thrombolysis,they were divided into non-HT group and HT group,and the expression levels of serum miR-9-5p,miR-21-5p and miR-206 were compared between the two groups.The general data of patients with ACI-LAA were collected.Univariate and multivariate Logistic regression analysis were used to analyze the influencing factors of HT occurs in patients with ACI-LAA after thrombolysis.The receiver operating characteristic(ROC)curve was used to analyze the efficacy of serum miR-9-5p,miR-21-5p and miR-206 expression levels in predicting HT occurs after thrombolysis in patients with ACI-LAA.The patients with ACI-LAA were followed up for 90 d.According to the modified Rankin scale(mRS)score,the patients were divided into a good prognosis group and a poor prognosis group,and the expression levels of serum miR-9-5p,miR-21-5p and miR-206 were compared between the two groups.Univa-riate and multivariate Logistic regression analysis were used to analyze the influencing factors of poor progno-sis in patients with ACI-LAA.ROC curve was used to analyze the efficacy of serum miR-9-5p,miR-21-5p and miR-206 expression levels in predicting poor prognosis of patients with ACI-LAA.Results HT occurred in 74(27.92％)of 265 patients with ACI-LAA after thrombolysis.Compared with the non-HT group,the National Institutes of Health Stroke Scale(NIHSS)score atadmission,the proportion of hypertension,the proportion of infarct size ≥10 cm2,and the expression levels of serum miR-21-5p and miR-206 were significantly in-creased in the HT group(P＜0.05).However,the expression level of serum miR-9-5p was decreased(P＜0.05).Hypertension,high NIHSS score at admission,the proportion of infarct size ≥10 cm2,high expression of miR-21-5p and miR-206 were risk factors for HT occurs in patients with ACI-LAA after intravenous thrombolysis,and high expression of miR-9-5p was a protective factor(P＜0.05).The ROC curve showed that the area under the curve(AUC)and 95％CI of single and combined detection of serum miR-9-5p,miR-21-5p and miR-206 for predicting HT occurs were 0.796(0.726-0.866),0.779(0.711-0.846),0.784(0.714-0.854),0.891(0.839-0.943),respectively.Among 265 patients with ACI-LAA,83 patients(31.32％)had poor prognosis at 90 d of follow-up.Compared with the good prognosis group,the age,NIHSS score at admis-sion,the proportion of HT,the proportion of infarct size ≥10 cm2,and the expression levels of serum miR-21-5p and miR-206 were increased(P＜0.05),and the expression level of serum miR-9-5p was decreased(P＜0.05)in the poor prognosis group.Advanced age,high NIHSS score at admission,HT,infarct size ≥10 cm2,high expression of miR-21-5p,and high expression of miR-206 were risk factors for poor prognosis of ACI-LAA patients,and high expression of miR-9-5p was a protective factor(P＜0.05).The ROC curve showed that The AUC(95％CI)of single and combined detection of serum miR-9-5p,miR-21-5p and miR-206 for predicting poor prognosis were 0.754(0.691-0.818),0.779(0.719-0.838),0.792(0.815-0.919),0.931(0.902-0.960),respectively.Conclusion Low expression of serum miR-9-5p,high expression of miR-21-5p and high expression of miR-206 are associated with the HT occurs and poor prognosis in patients with ACI-LAA after thrombolysis,and the combined detection of the three indicators has a high predictive value for the HT occurs and poor prognosis.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective:To evaluate the safety and efficacy of combined inflatable mediastinoscopy with laparoscopy guided by the concept of “reduced field and port” during esophagectomy for esophageal cancer.Methods:This is a retrospective cohort study. The clinical data of 497 patients with esophageal squamous cell carcinoma who underwent minimally invasive esophagectomy at the Center of Minimally Invasive Thoracic Surgery, the Second Affiliated Hospital of Naval Medical University, between January 2017 and December 2024 were retrospectively analyzed. There were 416 male and 81 female patients, with an age of (68.3±8.0) years (range: 44 to 89 years). Patients were divided into the traditional video-assisted thoracoscopic surgery group (Group A, n=354) and the combined inflatable mediastinoscopy with laparoscopic surgery group(Group B, n=143) based on the surgical approach. Furthermore, Group B was subdivided into the multiport laparoscopic group (Group B1, n=81) and the single-incision laparoscopic surgery plus one port group (Group B2, n=62). Perioperative indicators and postoperative survival differences were compared between the groups. Inter-group comparisons were performed using the independent sample t-test, χ2 test, or Fisher′s exact probability test. Survival curves were plotted using the Kaplan-Meier method, and the Log-rank test was used to analyze the survival differences between groups. Results:Compared with Group A, Group B demonstrated a significantly shorter operative time ((181.8±11.4) minutes vs. (196.7±8.1)minutes, t=16.09, P<0.01), a lower incidence of postoperative pulmonary complications (8.4% (12/143) vs. 17.8% (63/354), χ2=6.27, P=0.012), lower perioperative mortality (0 vs. 3.1%(11/354), P=0.039), and a shorter postoperative hospital stay ((16.2±2.2)days vs. (18.9±4.1)days, t=8.56, P<0.01). There was no significant difference in the anastomotic leak rate, number of lymph nodes dissected, or intraoperative blood loss between the two groups (all P>0.05). Overall survival time and recurrence-free survival time showed no significant difference between the two groups (all P>0.05). Subgroup analysis revealed no significant differences in perioperative indicators or postoperative complication rates between Group B1 and Group B2. Conclusions:Compared with traditional thoracoscopic combined with laparoscopic surgery, inflatable mediastinoscopy offered advantages in terms of lower postoperative pulmonary complication rates, shorter operative time, reduced postoperative hospital stay, and lower perioperative mortality. The “reduced field and port” concept could further minimize surgical trauma during the transmediastinal approach for esophagectomy while ensuring surgical safety and efficacy.

Objective:To quantitatively analyze right ventricular reverse remodeling in patients with severe tricuspid regurgitation after transcatheter tricuspid edge-to-edge repair (T-TEER) by two-dimensional speckle tracking echocardiography, and to preliminarily evaluate the clinical efficacy of this procedure.Methods:This study was a prospective single-center cohort study. Patients diagnosed with severe tricuspid regurgitation at the Xiamen Cardiovascular Hospital Xiamen University from March 2021 to June 2023 were enrolled. All patients underwent transthoracic echocardiography and transesophageal three-dimensional echocardiography before T-TEER, and transthoracic echocardiography at 30 days, 6 months, and 9 months after T-TEER. The primary endpoint was major adverse cardiovascular and cerebrovascular events, including death, stroke, myocardial infarction, reoperation, arrhythmia, and conduction block. Other clinical evaluation indicators included New York Heart Association (NYHA) functional classification and tricuspid regurgitation grade.Results:A total of 34 patients were enrolled, aged (67.9±9.3) years, and 71% (24/34) were female. The median follow-up duration was 9 months. All patients achieved a reduction of tricuspid regurgitation by ≥2 grades at 9 months after T-TEER, with 79% (27/34) of them having mild to moderate tricuspid regurgitation. Transthoracic echocardiography at 9 months after T-TEER showed that the vena contracta width of tricuspid regurgitation ((5.42±2.33) mm vs. (11.54±4.05) mm, P<0.001), effective regurgitant orifice area ((0.24±0.09) cm2 vs. (0.52±0.14) cm2, P<0.001), regurgitant jet area ((7.95±4.02) cm2 vs. (13.93±6.10) cm2, P<0.001), inferior vena cava diameter ((19.38±2.63) mm vs. (23.56±3.31) mm, P<0.001), right ventricular end-diastolic diameter ((28.03±6.26) mm vs. (33.21±8.24) mm, P=0.001), and tricuspid annular diameter ((36.47±4.40) mm vs. (41.44±7.08) mm, P<0.001) were all reduced compared with baseline; while the tricuspid annular plane systolic excursion ((18.08±5.25) mm vs. (14.91±3.42) mm, P=0.005) and right ventricular fractional area change ((37.61±7.52)% vs. (30.79±9.06)%, P=0.004) were both increased compared with baseline. At 9 months after T-TEER, all patients had a NYHA functional classification of grade Ⅰ or Ⅱ, and no major adverse cardiovascular and cerebrovascular event occurred during the follow-up period. Conclusion:It is preliminarily confirmed that T-TEER is safe and effective in the treatment of severe tricuspid regurgitation, with significant right ventricular reverse remodeling observed in patients at 9 months after T-TEER.

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.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Urolithiasis represents a prevalent clinical challenge marked by high recurrence rates and morbidity，with existing preventive strategies struggling to effectively curb its epidemic trajectory，thereby posing a significant threat to public health. The etiology of this condition is intricate，involving a complex network of interactions spanning classical supersaturation-crystallization theory，Randall’s plaque theory，and multifactorial elements such as cellular injury，inflammatory responses，metabolic derangements，the gut-kidney axis，immune dysregulation，and genetic predisposition. However，the critical mechanisms initiating stone formation and the early pathophysiological processes remain incompletely elucidated，constituting the core impasse in current preventive strategies. This review systematically synthesizes classical theories and cutting-edge advancements in urolithiasis etiology research，emphasizing the urgent need to integrate emerging technologies，including high-dimensional omics，advanced imaging modalities，and artificial intelligence，to dissect pivotal pathological nodes in early stone formation. Such interdisciplinary efforts are essential to overcome cognitive bottlenecks and ultimately achieve personalized，precision-based prevention strategies.
