Colchicine, a classic anti-inflammatory agent, has been long used for the prevention and treatment of gouty arthritis and familial Mediterranean fever. Given the pivotal role of inflammation in the development and progression of cardiovascular diseases, the clinical value of colchicine in the secondary prevention of cardiovascular diseases has attracted significant attention. Diabetes mellitus （DM） leads to severe and irreversible vascular complications, and cardiovascular diseases are the leading cause of death in patients with DM. However, existing research indicated heterogeneity in the therapeutic efficacy of colchicine among patients with cardiovascular diseases and those with diabetes complicated by cardiovascular conditions. The heterogeneity manifests as differences in efficacy across various disease stages, patient baseline characteristics, specific cardiovascular event types, endpoint definitions, and treatment regimens. The current domestic and international research findings on colchicine in relation to cardiovascular events—both in patients with CVD and in those with diabetes—were reviewed, with the aim of elucidating the underlying causes of this efficacy heterogeneity and providing evidence-based guidance for identifying patients likely to benefit and optimizing individualized treatment strategies in clinical practice.

Objective To investigate the short and medium term results of Castor single branched stent combined with parallel stent technique in the reconstruction of two supra-aortic branches in total endovascular repair of aortic arch lesions. Methods The patients with aortic arch disease who were treated with single-branch stents combined with parallel stents for Z1 anchoring and total endovascular repair from April 2022 to August 2022 in the Department of Cardiovascular Surgery of the First Affiliated Hospital of University of Science and Technology of China were retrospectively included, and the perioperative and follow-up data of the patients were analyzed. Results There were 4 males and 1 female with an average age of (46.2±18.6) years. This study included 1 patient of aortic arch aneurysm and 4 patients of acute non-A non-B aortic dissection. The success rate of surgical technique was 100.0%. The operative time was (132.3±45.1) min, the immediate postoperative isolation of lesions was satisfactory, and there were no adverse events and death in perioperative period. The follow-up time was 12-15 months. During the follow-up period, all patients survived without stent displacement, type Ⅰa endoleak, parallel stent stenosis and occlusion, or re-operation. Conclusion The short and medium term results of single branched stents combined with parallel stents in total endovascular repair of aortic arch diseases requiring Z1 anchoring is satisfactory.

AIM:To investigate the therapeutic effects and potential mechanism of pachymic acid(PA)on li-popolysaccharide(LPS)-induced acute kidney injury(AKI)in mice.METHODS:(1)Genes related to AKI were screened using the DAVID database.Core genes were identified by intersecting related genes and analyzed using Cyto-scape software.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analyses were performed through the DAVID database for the cross-targets.Molecular docking and activity assays were conducted on the primary core targets.(2)A total of 100 C57BL/6J mice were randomly divided into five groups:normal control(NC),model(LPS),solvent control(LPS+DMSO),and treatment groups(LPS+PA-10 and LPS+PA-20),with 20 mice in each group.The LPS-AKI model was established by intraperitoneal injection of 18 mg/kg LPS.The treatment groups received 10 mg/kg and 20 mg/kg PA,respectively,and the solvent control group was administered an equivalent dose of DMSO.Mice were euthanized 24 h after injection.Serum was collected for biochemical analysis,and Western blot was used to detect neutro-phil gelatinase-associated lipocalin(NGAL),kidney injury molecule-1(KIM-1),caspase-3,cleaved caspase-3,interleu-kin-1β(IL-1β),and monocyte chemoattractant protein-1(MCP-1)protein expression.RT-qPCR was employed to detect inflammatory factor mRNA levels.Molecular docking was used to simulate the optimal binding site of PA to caspase-3.En-zyme activity assays were performed to assess caspase protein activity,and renal lesions were observed via hematoxylin and eosin(HE)staining.Apoptosis was detected by TUNEL staining.RESULTS:(1)Thirty-one potential targets of PA against AKI were identified through network pharmacology.GO and KEGG enrichment analyses indicated that these tar-gets were primarily involved in immune response,inflammatory processes,apoptosis and survival,angiogenesis and hemo-dynamics,oxidative stress,and endoplasmic reticulum stress.Key targets included CASP3(caspase-3),PTGS2,BCL2,CCL2,and CYP219.(2)PA treatment improved renal function and reduced tubular epithelial injury.It significantly de-creased NGAL,KIM-1,and cleaved caspase-3 protein levels,as well as inflammatory factors TNF-α,IL-1β,and MCP-1 mRNA and protein expression.PA also reduced apoptosis of renal tubular epithelial cells.Enzyme activity assays and mo-lecular docking revealed that PA exerted its anti-apoptotic effect by directly binding to caspase-3,thereby inhibiting its ac-tivation by caspase-8.CONCLUSION:PA demonstrated a therapeutic effect in LPS-AKI,potentially through the inhibi-tion of inflammatory factor synthesis and release,as well as the inhibition of caspase-3 activation by caspase-8,reducing apoptosis in renal tubular epithelial cells.

Objective:To evaluate the short-term efficacy of endoscopic-laparoscopic regional gastric resection combined with sentinel lymph node basin dissection in patients with early-stage gastric cancer.Methods:This is a retrospective case series study. Data of 17 consecutive early gastric cancer patients from a prospective cohort at Beijing Friendship Hospital,Capital Medical University were analyzed between August 2023 and August 2024. Sixteen cases were from the department of general surgery and 1 from the department of gastroenterology. The cohort included 9 males and 8 females,with a mean age of 61.4 years (range: 46 to 79 years). Clinical data,including demographics,pathological features,surgical procedures,and follow-up outcomes,were collected through medical records and databases. All patients were followed for over 3 months,with follow-up ending on December 5,2024.Results:A total of 17 patients were involved. Among them, 5 patients underwent endoscopic submucosal dissection (ESD) combined with laparoscopic sentinel lymph node dissection (LSBD),and another 3 patients who underwent complete ESD resection received LSBD due to pathological stage meeting the expanded indications. 6 patients who underwent non-curative ESD resection received laparoscopic gastric regional resection (LRG) combined with LSBD,and another 3 patients directly received LRG combined with LSBD. The average number of sentinel lymph nodes dissected before surgery ( M(IQR)) was 8.9 (4.5) (range: 4 to 21),and the detection rate and accuracy rate were both 100%. Postoperative pathology confirmed that there was no metastasis in the sentinel lymph nodes of 5 patients who underwent ESD combined with LSBD and 3 patients who underwent LSBD after complete ESD resection. The vertical and horizontal margins of ESD were all negative. One patient was an absolute indication for ESD. For the 6 patients who underwent non-curative ESD resection combined with LRG and LSBD,the horizontal margins were all negative. Two patients showed 1 metastasis in each of the 21 and 9 sentinel lymph nodes during the operation,and additional distal gastrectomy was performed during the operation. Postoperatively,73 and 39 lymph nodes were retrieved respectively. The former had 1 additional metastasis,while the latter had no metastasis. Among the 3 patients who underwent direct LRG combined with LSBD,the horizontal margins were negative. One patient was confirmed as an absolute indication for ESD by postoperative pathology,and one patient had 1 metastasis in 8 sentinel lymph nodes during the operation,and additional distal gastrectomy was performed. Postoperatively,there was no metastasis in 54 lymph nodes. All patients had no complications such as infection,bleeding,perforation,or death after surgery. Among the 14 patients who did not receive additional radical surgery,they were able to pass gas and defecate within 3 days after surgery,with an average hospital stay of 6 days. The nutritional indicators and gastric radionuclide emptying imaging half-emptying time were similar to those before surgery at 3 months after surgery. Conclusions:Laparoscopic and endoscopic cooperative regional gastrectomy with sentinel lymph node basin dissection has the advantages of minimal invasiveness,preservation of gastric function,and precise treatment. It maybe suitable for patients with early-stage gastric cancer at high risk of lymph node metastasis and has good short-term efficacy.

Objective:To analyze the distribution characteristics of sports facilities in China using geographic information system (ArcGIS) and to investigate their association with mortality risk among residents.Methods:This prospective cohort study included 97 912 community residents from the Chinese Family Database (CFD) between 2013 and 2017. After excluding participants lost to follow-up and those with incomplete data, 53 937 individuals were retained for the analysis. The distribution characteristics of sports facilities in China was mapped using ArcGIS, and the death events were recorded via structured interviews and questionnaires. The Poisson regression was used to assess the association between the distribution characteristics of sports facilities near participants′ residences and their mortality risk.Results:In 2013, a total of 79 714 sports facilities were identified across 262 districts (counties) in China, with large-scale sports facilities accounting for the highest proportion (87.09%). The median number of sports facilities within the residential buffer zone was 17 (4, 30), and the median distance from the residence to the nearest sports facility was 453.2 (341.5, 1 863.5) m. Among the 53 937 community residents analyzed in this study, there were 27 761 males and 26 176 females, 1 326 deaths (2.5%) occurred during the follow-up. Poisson regression revealed that a higher number of sports facilities in the buffer zone (≥21 vs 0-2) was associated with lower mortality risk ( RR=0.74, 95% CI: 0.64-0.85; P0.05). Subgroup analyses showed that being≥60 years old ( RR=0.82, 95% CI: 0.70-0.95), males ( RR=0.78, 95% CI: 0.64-0.95), females ( RR=0.79, 95% CI: 0.64-0.97), having a junior high school education or less ( RR=0.84, 95% CI: 0.71-0.99), and having a urban residence ( RR=0.77, 95% CI: 0.66-0.90) were all negatively associated with residents′ mortality risk (all P0.05). After adjusting for age, greater distance to the nearest sports facility ( RR=1.41, 95% CI: 1.08-1.83) and failing to meet the"10-minute fitness circle"criterion ( RR=1.25, 95% CI: 1.02-1.53) were associated with higher mortality risk among males (both P0.05). After adjusting for age and gender, urban residents with a greater distance to the nearest sports facility ( RR=1.29, 95% CI: 1.04-1.60) or not meeting the 10-minute fitness circle ( RR=1.18, 95% CI: 1.00-1.38) showed a significantly higher mortality risk (both P0.05). Conclusions:The ArcGIS analysis revealed that the distribution of sports facilities in China is characterized by a high proportion of large-scale facilities. Lower facility density within residential buffer zone and greater distance to the nearest facility increase mortality risk among adults.

Objective:To evaluate the association between pre-pregnancy urolithiasis and pre-eclampsia and to further explore the mediating effect of hyperuricemia in early pregnancy on the relationship between urolithiasis and pre-eclampsia.Methods:Pregnant women attending prenatal care in early pregnancy at 7 Maternal and Child Health Hospitals in Hunan Province from August 2014 to December 2019 were recruited to construct a cohort of early pregnancy. The paper questionnaire collected demographic data on pregnant women, pre-pregnancy disease history, and living habits, etc. Besides, the early pregnancy laboratory examination and pregnancy outcome for this pregnancy were derived from the hospital's electronic medical record system. Logistic regression models were used to analyze the association between pre-pregnancy urolithiasis and pre-eclampsia, and causal mediation analysis was used to investigate the mediating role and magnitude of hyperuricemia in early pregnancy in the association pathway between pre-pregnancy urolithiasis and pre-eclampsia. Results:A total of 33 579 naturally conceived singleton pregnant women were included in the analysis, of which 3 230 cases (9.6%) had hyperuricemia in early pregnancy, and 666 cases (2.0%) had pre-eclampsia. The multivariate logistic regression analysis indicated that pre-pregnancy urolithiasis increased the risk of pre-eclampsia ( OR=2.65, 95% CI: 1.56-4.51). Mediation analysis showed that after controlling for confounders, hyperuricemia in early pregnancy could mediate the association between pre-pregnancy urolithiasis and pre-eclampsia, with a mediation effect proportion of 46% ( P<0.05). Conclusions:Pre-pregnancy urolithiasis is an independent risk factor for pre-eclampsia, and early pregnancy hyperuricemia has a certain mediating effect between urolithiasis and pre-eclampsia.

Objective:To evaluate the diagnostic performance of artificial intelligence-assisted diagnostic systems in cervical cytopathological examination.Methods:Cervical cytology slide data were retrospectively collected from four hospitals for the external validation of the developed artificial intelligence-assisted diagnostic system. Subsequently, prospective data collection was conducted for human-machine assisted studies.Results:In the retrospective study, a total of 3 162 valid samples were collected as external validation data. The system showed an area under the curve (AUC) of 0.890 (95% CI: 0.878-0.902), accuracy of 0.885 (95% CI: 0.873-0.896), sensitivity of 0.928 (95% CI: 0.914-0.941), and specificity of 0.852 (95% CI: 0.834-0.867). In the prospective study, 212 valid samples were collected, and five junior cytologists participated in the human-machine assisted study. Without artificial intelligence assistance, the average AUC for the five cytologists was 0.686 (95% CI: 0.650-0.722), the accuracy was 0.699 (95% CI: 0.671-0.727), the sensitivity was 0.653 (95% CI: 0.599-0.703), the specificity was 0.719 (95% CI: 0.685-0.750), the Fleiss κ value was 0.510, and the reading time was 223 seconds. With artificial intelligence assistance, the AUC, accuracy, sensitivity, and specificity increased by 0.166, 0.143, 0.225, and 0.107, respectively. Additionally, Fleiss κ was 0.730 and the reading time decreased by 188 seconds. All differences were statistically significant (all P<0.001). Conclusions:Artificial intelligence-assisted diagnosis system shows excellent performance and good generalizability, significantly improving the diagnostic accuracy, consistency, and efficiency of junior cytologists. It can be an effective auxiliary tool for junior cytologists in clinical practice.

OBJECTIVES: To investigate the chain mediating role of family care and emotional management in the relationship between social support and anxiety among rural primary school students. METHODS: A questionnaire survey was conducted among students in grades 4 to 6 from four counties in Hunan Province. Data were collected using the Social Support Rating Scale, Family Care Index Scale, Emotional Intelligence Scale, and Generalized Anxiety Disorder -7. Logistic regression analysis was used to explore the influencing factors of anxiety symptoms. Mediation analysis was conducted to assess the chain mediating effects of family care and emotional management between social support and anxiety. RESULTS: A total of 4 141 questionnaires were distributed, with 3 874 valid responses (effective response rate: 93.55%). The prevalence rate of anxiety symptoms among these students was 9.32% (95%CI: 8.40%-10.23%). Significant differences were observed in the prevalence rates of anxiety symptoms among groups with different levels of social support, family functioning, and emotional management ability (P<0.05). The total indirect effect of social support on anxiety symptoms via family care and emotional management was significant (β=-0.137, 95%CI: -0.167 to -0.109), and the direct effect of social support on anxiety symptoms remained significant (P<0.05). Family care and emotional management served as significant chain mediators in the relationship between social support and anxiety symptoms (β=-0.025,95%CI:-0.032 to -0.018), accounting for 14.5% of the total effect. CONCLUSIONS Social support can directly affect anxiety symptoms among rural primary school students and can also indirectly influence anxiety symptoms through the chain mediating effects of family care and emotional management. These findings provide scientific evidence for the prevention of anxiety in primary school students from multiple perspectives.
