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.

AIM: To investigate the application of deep optical coherence tomography(DRI-OCT)combined with IOL Master 500 in measuring choroidal thickness and axial length(AL)in pediatric myopic patients, and analyze the relationship between choroidal thickness and AL.METHODS: Prospective study. A total of 210 pediatric myopia patients(210 eyes)admitted between August 2021 and August 2024 were enrolled. Based on spherical equivalent(SE)measurements, they were categorized into a low myopia group(-3.00 D 0.05). Intraocular pressure, SE, AL, and choroidal thickness at different locations all showed significant differences(all P<0.001). Pearson correlation analysis revealed that AL negatively correlated with choroidal thickness(both P<0.001). The results of multiple linear regression analysis indicate that intraocular pressure, SE, and AL are factors influencing choroidal thickness(all P<0.001).CONCLUSION:DRI-OCT combined with IOL Master 500 is able to detect choroidal thickness and AL well, in addition, choroidal thickness closely correlated with intraocular pressure, SE and AL levels.

Objective: To explore the development history trends and research hotspots in children and adolescent overweight and obesity studies, so as to provide a basis for conducting scientific research in related fields. Methods: Relevant literature were retrieved from CNKI, WanFang Data Knowledge Service Platform, VIP Chinese Journal Service Platform, China Biomedical Literature Service System, Web of Science Core Collection and PubMed database from January 1980 to September 2024, and knowledge graph was constructed by using CiteSpace visualization software to explore and analyze. Results: A total of 9 108 articles were retrieved (5 197 in Chinese and 3 911 in English). From 1980 to 2024, the number of publications in the field of overweight and obesity research in children and adolescents showed an upward trend. Keyword cooccurrence analysis showed that body fat percentage (intermediary centrality:0.69), body mass index (intermediary centrality:0.50) and physical activity (intermediary centrality:0.13) were the bridge keywords connecting the research field. The keyword clustering results showed that coexistence outcomes of multiple diseases such as cardiovascular metabolic diseases and psychological disorders, as well as intervention plans based on family, school and community became research hotspots. The evaluation of the effects of highintensity interval training and emerging weight loss interventions such as electronic games gradually became a new trend in research. Conclusion Influencing factors, coexistence outcomes of multiple diseases, and the application and evaluation of intervention remain key research focuses in children and adolescent overweight/obesity studies.

The gradient field, one of the core magnetic fields in magnetic resonance imaging (MRI) systems, is generated by gradient coils and plays a critical role in spatial encoding and the generation of echo signals. The uniformity or linearity of the gradient field directly impacts the quality and distortion level of MRI images. However, traditional point measurement methods lack accuracy in assessing the linearity of gradient fields, making it difficult to provide effective parameters for image distortion correction. This paper introduced a spherical measurement-based method that involved measuring the magnetic field distribution on a sphere, followed by detailed magnetic field calculations and linearity analysis. This study, applied to assess the nonlinearity of asymmetric head gradient coils, demonstrated more comprehensive and precise results compared to point measurement methods. This advancement not only strengthens the scientific basis for the design of gradient coils but also provides more reliable parameters and methods for the accurate correction of MRI image distortions.

Cancer-associated venous thromboembolism(CAT)refers to the presence of venous thromboem-bolism including deep vein thrombosis and pulmonary embolism in patients with malignant cancer.Studies have indicated that CAT has become the second leading cause of death among cancer patients.Similar to other methods used to prevent and treat venous thromboembolism,anticoagulation remains to be the primary approach for CAT.However,the occurrence of CAT is influenced by various factors such as tumor type,staging,complications,treat-ment,and prognosis.This complexity makes the prevention and management of CAT more difficult and challeng-ing.This article reviews the classification of commonly used anticoagulant drugs in clinical practice,emphasizing the current status and advancements in their application for the prevention and treatment of cancer-related venous thromboembolism in order to provide valuable reference for clinical medication.

Poliovirus receptor(PVR)family includes several immune checkpoint receptors such as T cell immunoglobulin and immunoreceptor tyrosine-based inhibition motif structural domains(TIGIT),CD96 and CD226,and their ligands CD155 and CD112,etc.PVR family members have sequence homology and highly interact with each other for synergistic stimulatory or inhibitory effects,forming a complex immunomodulatory network together.The co-signaling network formed by PVR family members is of great significance and has become a major hot spot in hematologic tumor immunotherapy in recent years.This review describes the structure of PVR family members,their mechanism of action,research progress in hematological tumors,and their prospects for application in the immunotherapy of hematologic tumors.

Background and purpose:Human papilloma virus(HPV)infection status is crucial for diagnosing cervical precancerous lesions and classifying cervical cancer.High-risk(HR)HPV is often linked to P16 protein overexpression,so P16 detection via immunohistochemistry(IHC)is commonly used to assess HPV infection.However,the differences between HPV status and P16 expression remains unclear.An in-depth study of the correlation between HPV and P16 is essential for clinical guidance.Methods:We retrospectively collected clinical and pathological data of cervical lesions from 618 patients diagnosed at the Department of Pathology,Fudan University Shanghai Cancer Center from January 2020 to December 2023(Ethical number:050432-4-2307E).Polymerase chain reaction(PCR)reverse dot hybridization was used to detect HPV including HR and low-risk(LR)subtypes,and immunohistochemistry was used to detect P16 for comparative analysis.Based on different clinical and pathological diagnoses,the sensitivity and specificity of P16 expression in evaluating HPV infection were evaluated.Among the 618 cases of cervical lesions,there were 92 cases of cervical squamous cell carcinoma,257 cases of cervical adenocarcinoma,79 cases of high-grade squamous intraepithelial lesions(HSIL),105 cases of low-grade squamous intraepithelial lesions(LSIL),and 85 cases of chronic cervical inflammation.Results:According to clinical diagnosis,the HR-HPV positive rate in cervical squamous cell carcinoma was 88.0%(81/92),the P16 positive rate was 91.3%(84/92),and the overall consistency rate between P16 and HPV detection was 90.2%(88/92);for HR-HPV infection,the sensitivity and specificity of P16 were 96.3%and 45.5%.The positive rate of HR-HPV in adenocarcinoma was 54.5%(140/257),the positive rate of P16 was 58.8%(151/257),and the overall consistency rate between P16 and HPV detection was 82.5%(212/257);for HR-HPV infection,the sensitivity and specificity of P16 were 87.9%and 76.1%.In HSIL,the HR-HPV positive rate was 75.9%(60/79),the positive rate of P16 was 70.9%(56/79),and the overall consistency rate between P16 and HR-HPV detection was 82.2%(65/79);for HR-HPV infection,the sensitivity and specificity of P16 were 85.0%and 73.7%.In LSIL,the HR-HPV positive rate was 73.3%(77/105),the positive rate of P16 was 8.5%(9/105),and the overall consistency rate between P16 and HR-HPV detection was 33.3%(35/105);for HR-HPV infection,the sensitivity and specificity of P16 were 10.4%and 96.4%.In chronic cervical inflammation,the HR-HPV positive rate was 20%(17/85),the positive rate of P16 was 0.0%(0/85);for HR-HPV infection,the sensitivity and specificity of P16 were 0.0%and 100.0%.There was a significant positive correlation between P16 positivity and HPV16/18 in cervical squamous cell carcinoma,adenocarcinoma,and HSIL(P=0.000),while there was no significant correlation in LSIL and chronic cervical inflammation(P＞0.05).Conclusion:In cervical squamous cell carcinoma and adenocarcinoma,the consistency of P16 expression and HPV DNA positivity are high,especially in HPV16/18 subtype.There is a good concordance between HR-HPV positivity and P16 protein overexpression.The positive expression of P16 in HSIL may initially reflect HPV infection status.However,in LSIL and chronic cervicitis,P16 expression may not accurately correlate with HPV infection.The inconsistency between P16 and HPV DNA testing could be influenced by multiple factors,including HPV subtypes,histopathological categories,specimen quality,and technical limitations.In clinical practice,it is recommended to conduct comprehensive analysis or employ multiple diagnostic methods to confirm HPV infection status for precise evaluation.

Objective:To investigate the infection rate of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) in patients with severe aplastic anemia (SAA) after intensive immunosuppressive therapy in combination with a thrombopoietin receptor agonist (lST+TPO-RA) as well as assess the clinical impact of treatment.Methods:A retrospective, case series study was undertaken involving patients with SAA who were admitted to Soochow Hopes Hematonosis Hospital, The First Affiliated Hospital of Soochow University, and Zhengzhou Third People′s Hospital from June 2022 to February 2025. Thirty patients with complete CMV and EBV monitoring data after IST+TPO-RA treatment were enrolled. The first activation time of CMV and EBV, the maximum viral load, the first negative conversion time, and blood routine tests within 3 days before CMV and EBV positivity, during the positive period, and within 3 days after turning negative were recorded. The patients were followed up for 9 months after the completion of IST. One-way analysis of variance was used to compare the changes of blood routine before and after virus positivity and after turning negative. The χ2 test was used to compare the viral infection rate and the therapeutic effect of IST between the two groups. Results:The 30 SAA patients comprised 15 males and 15 females with an average age of (40.0±16.9) years. Of the 30 patients, 18 (60.0%) were infected with CMV and 6 (20.0%) with EBV. Among them, 17 cases received rabbit anti-human thymocyte immunoglobulin (r-ATG) treatment (r-ATG group), 13 cases received porcine anti-human lymphocyte immunoglobulin (p-ALG) treatment (p-ALG group). The CMV infection rate was significantly higher in the r-ATG group than in the p-ALG group (15/17 vs. 3/13, χ2=13.03, P<0.001); meanwhile, the rate of EBV infection was only slightly higher in the r-ATG group than in the p-ALG group, and the difference did not reach statistical significance (5/17 vs. 1/13, χ2=2.17, P=0.196). In patients infected with CMV, neutrophil, hemoglobin, and platelet counts were significantly decreased during the infection phase, followed by significant increases after CMV clearance ( F=14.48, 11.38, 4.73; all P<0.05). No significant differences in treatment efficacy were found between the r-ATG and p-ALG groups at 3, 6, and 9 months post-IST (all P>0.05). Conclusions:This preliminary study showed that the incidence of CMV and EBV infection in patients with SAA increased after IST, with CMV infections occurring significantly more frequently than EBV infections. The CMV infection rate was significantly higher in patients treated with r-ATG than in those receiving p-ALG. CMV infection was associated with notable alterations in hematological parameters, highlighting the need for close clinical monitoring.

Objective:To observe the characteristics of gastrointestinal tract symptoms in patients with Parkinson′s disease (PD) and analyze the characteristics of these symptoms in patients with different PD subtypes.Methods:A total of 297 PD patients who were admitted to the Neurology Department of the Second Affiliated Hospital of Soochow University from November 2022 to March 2024 were enrolled. The gastrointestinal symptoms of PD patients were evaluated using Drooling Severity and Frequency Scale (DSFS), Sialorrhea Clinical Scale for Parkinson′s disease (SCS-PD), Drooling Rating Scale (DRS), Eating Assessment Tool 10 (EAT-10), Gastroparesis Cardinal Symptom Index (GCSI), and Rome Ⅳ diagnostic criteria. The patients were grouped based on the presence or absence of gastrointestinal symptoms. Additionally, they were stratified according to disease duration (≤2 years, 2-5 years, 5-10 years, and>10 years) and motor symptom subtype [tremor-dominant (TD) vs. postural instability and gait difficulty (PIGD)]. One-way ANOVA and logistic regression analysis were applied to examine between-group differences while Spearman correlation analysis was employed to assess correlations between clinical symptoms.Results:The average age of the patients with PD was 67.0 (60.0, 72.0) years, and 161 (54.2%) were male. The incidence of PD combined with gastrointestinal symptoms was, in descending order: constipation (191, 64.3%), salivation (155, 52.2%), gastroparesis (93, 31.3%), and dysphagia (68, 22.9%). Compared with PD patients without gastrointestinal symptoms, those with symptoms had higher scores in the RBD-HK [12.0 (5.0, 21.5) vs. 5.0 (0.0, 9.0), Z=-3.74, P=0.017], ESS [6.0 (2.0, 12.0) vs. 3.0 (0.0, 6.0), Z=-3.20, P=0.023], and MDS-UPDRS Part Ⅰ [9.0 (5.0, 14.0) vs. 5.0 (2.3, 9.0), Z=-3.61, P=0.014]. The severity of sialorrhea and deglutition disorders, along with the incidence of constipation, all increased with longer disease duration. Patients with the PIGD subtype had higher GCSI scores than those with the TD subtype [0.0 (0.0, 1.9) vs. 0.0 (0.0, 0.0), Z=-3.57, P=0.007]. Across the cohort, sialorrhea, deglutition disorders, gastroparesis, and constipation were positively associated with the H-Y stage, MDS-UPDRS Ⅰ, HAMD, NMSQ, and SCOPA-AUT; EAT-10 scores were negatively correlated with MoCA ( r=-0.171, P<0.05); and GCSI scores were negatively correlated with MMSE and MoCA ( r=-0.154, r=-0.169, both P<0.05). Conclusions:Overall, 84.5% of the patients with PD had one or more gastrointestinal symptoms, and the incidence and severity of gastrointestinal symptoms increased with disease duration. The severity of gastroparesis was higher in the PIGD group than in the TD group. The scores of all gastrointestinal symptoms were positively correlated with the H-Y stage and MDS-UPDRS Ⅰ, while the GCSI scores were negatively correlated with the cognitive scores.

Objective To explore the value of neutrophil extracellular trapping nets(neutrophil extracellular traps,NETs)in the diagnosis and monitoring of acute ischemic stroke(acute ischemic stroke,AIS).Methods From June 2023 to February 2024,63 patients newly diagnosed with AIS at the Ganmei Hospital Affiliated with Kunming Medical University were selected as the experimental group,and 58 non-AIS individuals matched in gender,age,and other characteristics were selected as the control group.The NETs levels of patients in the experimental group were detected before and 7-10 days after treatment,and general clinical data and related laboratory results were statistically analyzed.Results The experimental group showed significantly higher levels of NEUT,LYMPH,MONO,EO,FDP,D-dimer,and NETs compared to the control group(P<0.05).The NETs levels before treatment were significantly higher than those at 7～10 days after treatment and in the control group(P<0.05).The NETs levels 7～10 days after treatment were significantly higher than those in the control group(P<0.05).NEUT,MONO,FDP,D-dimer,and NIHSS scores were positively correlated with the pre-treatment NETs levels(P<0.05).Elevated serum NETs levels were associated with AIS risk factors(P<0.05).The combined diagnostic value of NEUT,D-dimer,and NETs for AIS was superior to other indicators.Conclusion NETs are highly expressed in the serum of patients with acute ischemic stroke,and serum NETs have certain value in the auxiliary diagnosis and monitoring of acute ischemic stroke.
