Objective: Patients with atherosclerotic cardiovascular disease (ASCVD) following percutaneous coronary intervention (PCI) are classified as very-high-risk individuals in cardiovascular disease (CVD) risk stratification. The distribution pattern of traditional Chinese medicine (TCM) syndromes in this patient population, as well as its association with blood lipid profiles and clinical prognosis, remains unclear. The present prospective cohort study aims to investigate these correlations, thereby providing insights to enrich the research fields. Methods: We enrolled consecutive patients with ASCVD who underwent PCI at the Integrated Cardiology Unit of China-Japan Friendship Hospital between September 1, 2020 and December 31, 2022. Demographics and clinical characteristics, signs and symptoms defining each TCM syndrome, and fasting venous blood samples were collected at baseline and follow up or upon major adverse cardiovascular events (MACEs). We analyzed the correlation between TCM syndromes, blood lipid profiles, and MACEs, and developed a new joint prognostic model incorporating both TCM syndromes and blood lipids using logistic regression. The analyses were based on detailed baseline and one-year follow-up data. Results: A per-protocol analysis was performed on 586 patients with complete data ultimately. During the one-year follow-up, 174 patients (29.69%) experienced a MACE. We performed statistical analyses on comorbidities, medication, and biochemical indicators across groups defined by TCM syndrome differentiation. When comparing different TCM syndromes, no significant differences were found in age, body mass index (BMI), history of revascularization, comorbidities, family history of CVD, smoking or drinking, or statin intensity (P > 0.05). Patients with intertwined phlegm and blood stasis syndrome exhibited significantly higher levels of total cholesterol (TC, 5.27 ± 1.18 mmol/L, P < 0.001), triglyceride (TG, 1.96 ± 1.33 mmol/L, P = 0.008), low-density lipoprotein cholesterol (LDL-C, 3.35 ± 0.79 mmol/L, P < 0.001), and high-density lipoprotein cholesterol (HDL-C, 1.24 ± 0.81 mmol/L, P < 0.001) compared with those with other TCM syndromes combined. A multivariable logistic regression model was constructed to predict MACEs. The model included TCM syndrome type [with intertwined phlegm and blood stasis as a predictor, adjusted odds ratio (OR) = 1.413, 95% confidence interval (CI): 0.517 – 3.864, P = 0.501], age (adjusted OR = 0.97, 95% CI: 0.955 – 1.001, P = 0.057), male gender (adjusted OR = 0.698, 95% CI: 0.416 – 1.170, P = 0.173), TC (adjusted OR = 1.004, 95% CI: 0.513 – 1.965, P = 0.990), and LDL-C (adjusted OR = 5.825, 95% CI: 2.214 – 15.326, P < 0.001). This model demonstrated good discriminatory ability for MACEs in post-PCI ASCVD patients [the area under the receiver operating characteristic (ROC) curve (AUC) = 0.865, 95% CI: 0.816 – 0.914]. Conclusion The intertwined phlegm and blood stasis TCM syndrome is associated with a distinct atherogenic lipid profile characterized by elevated levels of TC and LDL-C. The prognostic model that incorporates this TCM syndrome type along with conventional lipid parameters (TC and LDL-C) shows good discriminatory ability for predicting MACEs in ASCVD patients after PCI, underscoring the potential clinical utility of integrating TCM syndrome differentiation into CVD risk assessment.

Coronary heart disease with angina pectoris,characterized by myocardial ischemic injury as its fundamental pathological mechanism,represents a prevalent cardiovascular condition.The"State-Target Differential Diagnosis and Treatment"presents a holistic regulatory framework,integrating macroscopic state regulation with microscopic targeting.Guided by this approach,the pathological evolution of coronary heart disease is examined through four dimensions:"state-target-cause-effect."The"cause"encompasses both the pathogenesis and etiological factors of traditional Chinese and Western medicine.The"effect"manifests as adverse cardiovascular events,including myocardial infarction and heart failure.The"state"delineates the progressive development pattern of qi to blood to deficiency,beginning with qi stagnation and cold congealment in the initial stage,followed by blood stasis and phlegm obstruction in the intermediate stage,and culminating in qi-blood deficiency in the advanced stage.The"target"encompasses multi-level therapeutic interventions addressing both symptomatic manifestations and clinical indicators.Building on this theoretical foundation,this research focuses on the pattern of qi sinking and blood stasis commonly observed in late-stage angina,systematically elucidating its state regulation and targeting therapeutic strategies.Using the clinical empirical formula Shengxian Quyu Decoction as the baseline state prescription,an in-depth investigation was conducted to determine optimal combination patterns of symptom-and biomarker-targeted medications.This study aims to establish a modernized differential treatment system for angina pectoris with the pattern of qi sinking and blood stasis,providing novel research perspectives and theoretical foundations for enhancing clinical efficacy and reducing the risk of cardiovascular events.

Objective:This study was to explore the behavioral and electroencephalographic characteristics of impaired cognitive flexibility in patients with obsessive-compulsive disorder (OCD) with comorbid obsessive-compulsive personality disorder(OCPD).Methods:A cross-sectional study was designed to collect data prospectively from OCD patients who visited the psychology departments at two top-tier hospitals in Changsha between September 2019 and December 2021. The study included 31 patients with OCD+OCPD(18 males, 13 females; aged 15-46 (22.8±8.4) years) and 39 patients with OCD only(25 males, 14 females; aged 15-34 (21.6±4.2) years). Additionally, 32 age-matched healthy controls(HC: 18 males, 14 females; aged 18-25 (20.8±1.7) years). All participants completed the Task-Switching paradigm while behaioral and event-related potentials(ERPs) were recorded simultaneously. Repeated measures analysis of variance was used to compare the group differences in behavioral and ERP data(electrode sites: FZ, FCZ, CZ, PZ; ERP components: amplitude and latency of P2, N2, and P3).Results:The reaction times in both the comorbid and OCD groups were significantly longer than those in the healthy control group ((1 182±287) ms and (1 119±194) ms vs. (886±95) ms; F=18.48, both P<0.001). Accuracy rates in the comorbid and OCD groups were also significantly lower than in the healthy control group ((77±14)% and (77±13)% vs. (84±7)%; F=4.00, both P<0.05). In the task-switching condition, the N2 latency at the CZ electrode was significantly shorter in the comorbid and OCD groups compared to the healthy control group ((290±22) ms and (291±29) ms vs. (308±27) ms; F=3.81, both P<0.05). Furthermore, at the FZ and FCZ electrodes, the N2 latency in the comorbid group was significantly shorter in the switching task compared to the repetition task. Conclusion:OCD patients with comorbid OCPD show more severe cognitive flexibility impairments and display abnormal electrophysiological patterns.
