Cardiovascular diseases （CVD）， particularly atherosclerosis， represent a major global health burden. Recent studies have revealed that innate immune cells such as monocytes and macrophages can develop immune memory after an initial stimulus， a phenomenon termed “trained immunity”. Growing evidence indicates that trained immunity serves as an underlying mechanism of chronic inflammation in atherosclerotic cardiovascular diseases. This review focuses on outlining the key effector cells involved in trained immunity and their mechanisms of formation， including processes such as metabolic reprogramming and epigenetic modifications， which collectively lead to a heightened immune response upon secondary stimulation. Furthermore， this review systematically summarizes the role of trained immunity in the initiation and progression of atherosclerosis， and elaborates on various therapeutic strategies targeting trained immunity along with their application prospects.

Inclusion criteria：①chronic spinal cord injury patients over 18 years old（with no progression of neurological symptoms within 3 months）；② presence of NDO and AD；③ inadequate response or intolerance to oral antimuscarinic agent（M-receptor antagonists or β 3-receptor agonists）④ perform clean intermittent catheterization to empty the bladder. Exclusion criteria：① primary disease in the acute or progressive phase；② previous surgeries that would affect lower urinary tract function，such as transurethral sphincterotomy，bladder neck resection，prostatectomy，or bladder surgery；③ allergy to BTX-A or its adjuvants，or those with allergic predisposition ④ patients who were pregnant，breastfeeding，or planning for pregnancy in the near future；⑤ patients did not accept or were unable to perform intermittent catheterization. Before treatment，all patients were required to maintain 3-5 day urine diary，along with urodynamic studies（UDS），incontinence specific quality of life instrument（I-QOL）and AD symptom severity assessment，and blood pressure monitored. Key UDS parameters recorded included maximum bladder capacity，maximum detrusor pressure during filling phase，changes in maximum systolic blood pressure（SBP）relative to baseline（ΔSBP）during UDS examination，and the frequency of 24-hour blood pressure exceeding baseline by 20 mmHg. After general anesthesia or epidural anesthesia，BTX-A（200 U）was injected into the bladder at 30 points（including the triangle）under the cystoscope using a special injection needle，6.7 U per injection，and then the catheter was kept for 3-5 days after treatment. Three months later，relevant indicators were collected and compared with pre-treatment data. Results:A total of 43 patients were included in this study，including 34 males and 9 females. The age was（39.23±13.17）years old and the disease course was（2.69±3.27）years old. There were 33 cervical and 10 thoracic cases. The American Spinal Injury Association Injury Scale score distribution was as follows：26（60%）A，4（9%）B，9（21%）C，and 4（9%）D. The presence of AD was confirmed in all patients during urodynamic examination（UDS），that was the systolic blood pressure（SBP）suddenly increased and exceeded 20 mmHg（1 mmHg = 0.133 kPa）. Before treatment，The AD symptoms severity score（consist of headache，sweating，goose bumps，anxiety and palpitation）were（14.53±2.51），Bladder-related AD frequency was 10.67 episodes/day. Baseline SBP was（103.51±9.64）mmHg，the maximum SBP was（150.40±22.75）mmHg，and the change in SBP（ΔSBP）from maximum to baseline SBP during UDS examination was（43.83±21.01）mmHg. The UDS indicated that the maximum detrusor pressure during storage phase was（54.95±24.68）cmH 2O，and the bladder capacity was（131.70±75.29）ml. Bladder diary showed the volume of catheterization each time from was（181.16±49.86）ml，and The I-QOL score was（44.07±8.60）. Three months after treatment，the AD symptoms severity score（consist of headache，sweating，goose bumps，anxiety and palpitation）were（11.37±2.39）. The frequency of bladder-related AD episodes was（7.51±2.37）episodes/day，showing statistically significant differences compared to pre-treatment（ P<0.05）.The SBP before UDS examination was（102.12±10.28）mmHg，with no statistically significant difference from baseline（ P = 0.518）. The maximum SBP in perfusion phase and the ΔSBP were（132.84±16.30）mmHg and（28.72 ± 14.02）mmHg，respectively，both demonstrating statistically significant differences（ P < 0.05）. The UDS examination revealed that the maximum detrusor pressure during the storage phase was（29.77±13.72）cmH 2O，showed a significant decrease，and the bladder capacity was（272.63±79.75）ml，which were both statistically different before and after surgery. Bladder diary showed the volume of catheterization each time was（326.74±63.71）ml；I-QOL score was（71.86±11.45），both were significant different after treatment（ P < 0.01）. Conclusion:BTX-A intravesical injection in the treatment of NDO can also alleviate the severity and frequency of bladder related AD.

BACKGROUND: Based on the China-VHD database, this study sought to develop and validate a Valvular Heart Disease- specific Age-adjusted Comorbidity Index (VHD-ACI) for predicting mortality risk in patients with VHD. METHODS & RESULTS: The China-VHD study was a nationwide, multi-centre multi-centre cohort study enrolling 13,917 patients with moderate or severe VHD across 46 medical centres in China between April-June 2018. After excluding cases with missing key variables, 11,459 patients were retained for final analysis. The primary endpoint was 2-year all-cause mortality, with 941 deaths (10.0%) observed during follow-up. The VHD-ACI was derived after identifying 13 independent mortality predictors: cardiomyopathy, myocardial infarction, chronic obstructive pulmonary disease, pulmonary artery hypertension, low body weight, anaemia, hypoalbuminaemia, renal insufficiency, moderate/severe hepatic dysfunction, heart failure, cancer, NYHA functional class and age. The index exhibited good discrimination (AUC, 0.79) and calibration (Brier score, 0.062) in the total cohort, outperforming both EuroSCORE II and ACCI (P < 0.001 for comparison). Internal validation through 100 bootstrap iterations yielded a C statistic of 0.694 (95% CI: 0.665-0.723) for 2-year mortality prediction. VHD-ACI scores, as a continuous variable (VHD-ACI score: adjusted HR (95% CI): 1.263 (1.245-1.282), P < 0.001) or categorized using thresholds determined by the Yoden index (VHD-ACI ≥ 9 vs. < 9, adjusted HR (95% CI): 6.216 (5.378-7.184), P < 0.001), were independently associated with mortality. The prognostic performance remained consistent across all VHD subtypes (aortic stenosis, aortic regurgitation, mitral stenosis, mitral regurgitation, tricuspid valve disease, mixed aortic/mitral valve disease and multiple VHD), and clinical subgroups stratified by therapeutic strategy, LVEF status (preserved vs. reduced), disease severity and etiology. CONCLUSION The VHD-ACI is a simple 13-comorbidity algorithm for the prediction of mortality in VHD patients and providing a simple and rapid tool for risk stratification.

Microbial detection and control of traditional Chinese medicine(TCM) decoction pieces are crucial for the quality control of TCM preparations. It is also a key area of research in the measurement technology and equipment development for TCM manufacturing. Guided by TCM manufacturing measurement methodologies, this study presented a design of a novel portable microbial detection device, using Atractylodis Macrocephalae Rhizoma decoction pieces as a demonstration. Immunomagnetic separation technology was employed for specific isolation and labeling of target microorganisms. Enzymatic signal amplification was utilized to convert weak biological signals into colorimetric signals, constructing an optical biosensor. A self-developed smartphone APP was further applied to analyze the colorimetric signals and quantify target concentrations. A portable and automated detection system based on Arduino microcontroller was developed to automatically perform target microbial separation/extraction, as well as mimetic enzyme labeling and catalytic reactions. The developed equipment specifically focuses on the rapid and quantitative microbial analysis of TCM active pharmaceutical ingredients, intermediates in TCM manufacturing, and final TCM products. Experimental results demonstrate that the equipment could detect Salmonella in samples within 2 h, with a detection limit as low as 5.1 × 10~3 CFU·mL~(-1). The equipment enables the rapid detection of microorganisms in TCM decoction pieces, providing a potential technical solution for on-site rapid screening of microbial contamination indicators in TCM. It has broad application prospects in measurement technology for TCM manufacturing and offers strong technical support for the modernization, industrialization, and intelligent development of TCM.

Objective To establish a simplified simulation method of rocking-chair archwire(RCA),explore the biomechanical effect of RCA during anterior teeth retraction with sliding mechanics,and provide guidance for clinical treatment.Methods A standard 0.019 in×0.025 in(0.483 mm×0.635 mm)labial archwire was imported into ANSYS software and preloaded spring was used to simulate RCA at different angles to achieve parameterized modeling.A three-dimensional(3D)finite element model with labial straight wire appliance,teeth,periodontium and maxillary bone was established to analyze the displacement and force of anterior/posterior teeth under 1.5 N intra-arch traction combined with RCA at different angles.Results Preloading forces of 1.5,3,4.5,and 6 N in spring induced angles of approximately 5°,10°,15°,and 20° for RCA,demonstrating the flexibility and convenience of the parameterized modeling method.During intra-arch traction with increased angle of RCA,lingual crown displacement of the middle incisor gradually decreased,while the lateral incisor and canine showed decreased crown tipping and increased lingual root displacement;when the RCA angle was 20°,the lateral incisor and canine achieved almost bodily retraction.Meanwhile,premolars showed an extrusion tendency,while molars demonstrated distal crown tipping and intrusion tendency.As the RCA angle increased from 0° to 20°,intrusive force on the anterior teeth increased,and the moment-force ratio(M/F)at bracket level increased from 0 to near 9 mm.Conclusions RCA can effectively control the moving pattern of the maxillary anterior teeth and prevent their over-erection and extrusion during retraction with sliding mechanics.During intra-arch traction with rigid stainless steel archwire,theoretically RCA of 20° has sufficient torque control on the anterior teeth to achieve their en-masse retraction.
