The pathological changes of myocardial infarction （MI） are mainly characterized by progressive myocardial ischemic necrosis， decline in cardiac diastolic function， thinning of the ventricular wall， and enlargement of the ventricles. The clinical manifestations include myocardial ischemia， heart failure， arrhythmia， shock， and even sudden cardiac death， rendering MI one of the most perilous cardiovascular diseases. Currently， the clinical treatment for MI primarily involves interventional procedures and drug therapy. However， due to their significant side effects and high complication rates associated with these treatments， they fail to ensure a satisfactory quality of life and long-term prognosis for patients. On the other hand， traditional Chinese medicine has demonstrated remarkable potential in improving patient prognosis while reducing side effects. Research has elucidated that various signaling pathways such as nuclear transcription factor-κB （NF-κB）， adenosine 5̒-monophosphate-activated protein kinase （AMPK）， transforming growth factor-β （TGF-β）/Smads， mitogen-activated protein kinase （MAPK）， Wnt/β-catenin （β-catenin）， and phosphatidylinositol 3-kinase （PI3K）/protein kinase B（Akt） play crucial roles in regulating the occurrence and development of MI. Effectively modulating these signaling pathways through its therapeutic interventions， traditional Chinese medicine can enhance MI management by inhibiting apoptosis， providing anti-inflammatory properties， alleviating oxidative stress levels， and resisting myocardial ischemia. Due to its notable efficacy and favorable safety， it has become an area of focus in clinical practice.

【Objective】 To explore the effect of physical fitness training on social adaptive behavior of children with global developmental delay (GDD), in order to provide treatment experience for GDD children. 【Methods】 From November 2021 to December 2022, a total of 60 children with GDD diagnosed and treated in the Third Affiliated Hospital of Jiamusi University were enrolled in this study, and were randomly divided into control group (n=30) and test group (n=30).The control group received routine rehabilitation treatment, and the test group received physical fitness training additionally.The intervention lasted for 12 weeks, with the frequency of 3times/week, 30min/time.All subjects were tested for physical fitness and children′s social adaptive behavior before and after training. 【Results】 Before treatment, the difference between the results of physical fitness test and social adaptive behavior scores of the GDD children in two groups was not statistically significant (P>0.05).After 3 months of treatment, the physical fitness test scores, except body mass index (BMI), and social adaptive behavior scores of the GDD children in two groups were significantly different from those before treatment (P<0.05), and the physical fitness test scores (except for height, weight and BMI) and the social adaptive behavior of the test group were better than those of the control group (t=2.363,4.020,3.331,3.338,P<0.05). 【Conclusion】 Physical fitness training can significantly improve the adaptive behavior, independent function, cognitive function and social/self-control ability of GDD children.

This study searched the clinical researches on traditional Chinese medicine （TCM） for cardiovascular diseases registered in Chinese Clinical Trial Registry and the US Clinical Trial Registry， the cardiovascular disease-related studies funded by the National Natural Science Foundation of China， as well as those published in China National Knowledge Infrastructure （CNKI）， Wanfang database， VIP.com， China Biology Medicine disc （CBMdisc）， Embase， Medline， Cochrane Library， and other databases published cardiovascular disease-related studies from 1 January 2021 to 30 June 2023. In order to analyse and evaluate the research progress of TCM treatment for coronary heart disease， hypertension， heart failure， and arrhythmia， this study aimed at recent research hotspots and research direction. It is found that the research on TCM for cardiovascular diseases was gradually deepening and the high-quality evidence continued to emerge. It is believed that studies related to the prevention and treatment of common cardiovascular diseases by TCM reflected the multi-angle integration of modern technology and pattern differentiation and treatment， closer integration of clinical and basic research， and further optimisation of pattern identification and interventions. On this basis， the research programme and implementation process should be further standardized， and the translation of research results should be emphasized to promote the standardized application and promotion of TCM diagnosis and treatment of cardiovascular diseases.

Objective To investigate the spatiotemporal distribution characteristics and potential influencing factors of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, so as to provide insights into the formulation of the echinococcosis control strategy in Qinghai Province. Methods The number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases, number of registered dogs and number of stray dogs were captured from the annual reports of echinococcosis control program in Qinghai Province from 2016 to 2022, and the detection of newly diagnosed echinococcosis cases was calculated. The number of populations, precipitation, temperature, wind speed, sunshine hours, average altitude, number of year-end cattle stock, number of year-end sheep stock, gross domestic product (GDP) per capita, and number of village health centers in each county (district) of Qinghai Province were captured from the Qinghai Provincial Statistical Yearbook, and county-level electronic maps in Qinghai Province were downloaded from the National Platform for Common Geospatial Information Services. The software ArcGIS 10.8 was used to map the distribution of newly diagnosed echinococcosis cases in Qinghai Province, and the spatial autocorrelation analysis of newly diagnosed echinococcosis cases was performed. In addition, the spacetime scan analyses of number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases and geographical coordinates in Qinghai Province were performed with the software SaTScan 10.1.2, and the spatial stratified heterogeneity of the detection of newly diagnosed echinococcosis cases was investigated with the software GeoDetector. Results A total of 6 569 426 residents were screened for echinococcosis in Qinghai Province from 2016 to 2022, and 5 924 newly diagnosed echinococcosis cases were found. The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline over years from 2016 to 2022 (χ² = 11.107, P < 0.01), with the highest detection in Guoluo Tibetan Autonomous Prefecture in 2017 (82.12/10⁵). There were spatial clusters in the detection of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2018 (Moran’s I = 0.34 to 0.65, all Z values > 1.96, all P values < 0.05), and the distribution of newly diagnosed echinococcosis cases appeared random distribution from 2019 to 2022 (Moran’s I = −0.09 to 0.04, all Z values < 1.96, all P values > 0.05). Local spatial autocorrelation analysis showed high-high clusters and low-low clusters in the detection of new diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, and space-time scan analysis showed that the first most likely cluster areas of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022 were mainly distributed in Yushu Tibetan Autonomous Prefecture and Guoluo Tibetan Autonomous Prefecture. GeoDetector-based analysis of the driving factors for the spatial stratified heterogeneity of detection of newly diagnosed echinococcosis cases in Qinghai Province showed that average altitude, number of village health centers, number of cattle and sheep stock, GDP per capita, annual average sunshine hours, and annual average temperature had a strong explanatory power for the spatial distribution of newly diagnosed echinococcosis cases, with q values of 0.630, 0.610, 0.600, 0.590, 0.588, 0.537 and 0.526, respectively. Conclusions The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline in Qinghai Province over years from 2016 to 2022, showing spatial clustering. Targeted control measures are required in cluster areas of newly diagnosed echinococcosis cases for further control of the disease.

Background::Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized immune-mediated disorder that can affect almost any organ in the human body. IgG4-RD can be categorized into proliferative and fibrotic subtypes based on patients’ clinicopathological characteristics. This study aimed to compare the clinical manifestations, laboratory findings, and treatment outcomes of IgG4-RD among different subtypes.Methods::We prospectively enrolled 622 patients with newly diagnosed IgG4-RD at Peking Union Medical College Hospital from March 2011 to August 2021. The patients were divided into three groups according to their clinicopathological characteristics: proliferative, fibrotic, and mixed subtypes. We compared demographic features, clinical manifestations, organ involvement, laboratory tests, and treatment agents across three subtypes. We then assessed the differences in treatment outcomes among 448 patients receiving glucocorticoids alone or in combination with immunosuppressants. Moreover, risk factors of relapse were revealed by applying the univariate and multivariate Cox regression analysis.Results::We classified the 622 patients into three groups consisting of 470 proliferative patients, 55 fibrotic patients, and 97 mixed patients, respectively. We found that gender distribution, age, disease duration, and frequency of allergy history were significantly different among subgroups. In terms of organ involvement, submandibular and lacrimal glands were frequently involved in the proliferative subtype, while retroperitoneum was the most commonly involved site in both fibrotic subtype and mixed subtype. The comparison of laboratory tests revealed that eosinophils ( P = 0.010), total IgE ( P = 0.006), high-sensitivity C-reactive protein ( P <0.001), erythrocyte sedimentation rate ( P <0.001), complement C4 ( P <0.001), IgG ( P = 0.001), IgG1 (P <0.001), IgG4 (P <0.001), and IgA ( P <0.001), at baseline were significantly different among three subtypes. Compared with proliferative and mixed subtypes, the fibrotic subtype showed the lowest rate of relapse (log-rank P = 0.014). Conclusions::Our study revealed the differences in demographic characteristics, clinical manifestations, organ involvement, laboratory tests, treatment agents, and outcomes across proliferative, fibrotic, and mixed subtypes in the retrospective cohort study. Given significant differences in relapse-free survival among the three subtypes, treatment regimens, and follow-up frequency should be considered separately according to different subtypes.Trial Registration::ClinicalTrials. gov, NCT01670695.

Objective To observe the value of combined synthetic MRI and multiplexed sensitivity encoding diffusion weighted imaging(MUSE-DWI)for differentiating benign and malignant endometrial lesions.Methods Data of 112 patients with benign or malignant endometrial lesion confirmed by pathology were retrospectively analyzed.According to pathologic diagnosis,the patients were divided into malignant group(n=72)and benign group(n=40).Synthetic MRI and MUSE-DWI quantitative parameters,including T1,T2,proton density(PD)and apparent diffusion coefficient(ADC)of all lesions were acquired.The clinical data as well as ADC,T1,T2 and PD values of lesions were compared between groups,and those being significantly different between groups were included in univariate and multivariate logistic regression.Then the univariate and combined models were established for differentiating benign and malignant endometrial lesions.The receiver operating characteristic curves were drawn,and areas under the curves(AUC)were calculated to evaluated the diagnostic efficacy of the models,which were compared with DeLong test.Results Patients'age in malignant group were higher than that in benign group(P＜0.05).The length of the maximum diameter was larger,ADC,T2 and PD values were lower in malignant lesions than those in benign ones(all P＜0.05),while no significant difference of T1 value was found between groups(P=0.074).The AUC of ADC univariate model was 0.966,and there was no significant difference in AUC(0.970)between the combined ADC+T2+PD model(adjusted P＞0.05),but both higher than AUC of T2 univariate model(0.618),PD univariate model(0.664)and the combined T2+PD model(0.668)(all adjusted P＜0.05).Conclusion ADC univariate model and combined model with other parameters of combined synthetic MRI and MUSE-DWI could be used to effectively differentiate benign and malignant endometrial lesions.

Objective:To explore the sleep status and impact factor analysis of patients in clinical trials of antineoplastic drugs, and provide a basis for improving the sleep status and impact analysis of patients in clinical trials of antineoplastic drugs.Methods:From April to May 2023, 107 oncology patients in the Phase I Clinical Trial Ward of the Affiliated East Hospital of Tongji University were selected as the research objects by convenient sampling method. The general information questionnaire, Pittsburgh Sleep Quality Index Scale (PSQI), Numeric rating scale (NRS), Generalized Anxiety Disorder Scale (GAD-7) and Depression Self-Ration Tool Scale (PHQ-9). Multivariate Logistic regression analysis methods were used to carry out a cross-sectional investigation and the relevant factors affecting patients′sleep.Results:Totally 103 questionnaires were effectively collected. The 103 patients′ age ranged from 20 to 75 years old, including 61 males and 42 females. 47.57% (49/103) patients in clinical trials of antineoplastic drugs had abnormal sleep. The average score of patients (PSQI) (7.66 ± 3.93) was higher than the average score of the domestic norm (3.88 ± 2.52), and there was significant statistical difference ( t = 9.76, P<0.01). Logistic regression analysis showed that pain ( OR = 3.004, 95% CI 1.135-7.948, P<0.05) and trial cycle ( OR = 0.432, 95% CI 0.191-0.978, P<0.05) were significant risk factors for abnormal sleep quality. Conclusions:The incidence of abnormal sleep quality in patients of clinical trials of antineoplastic drugs is high, but the sleep quality is poor. The factors that affect the sleep quality of patients in clinical trials of antineoplastic drugs are mainly related to the patient′s trial cycle and cancer pain. According to these characteristics, individualized programs should be developed to improve the sleep quality of patients with advanced cancer, so as to improve the quality of life of patients with advanced cancer.

Objective:To evaluate the diagnostic efficacy of the novel prostate specific membrane antigen (PSMA)-targeted PET imaging agent 18F-AlF-P16-093 in combination with multiparametric MRI (mpMRI) for prostate cancer (PCa), and to explore its application in guiding transperineal puncture biopsy. Methods:A retrospective analysis was conducted on the clinical and pathological data of 36 patients diagnosed as PCa (age: 68-76 years) who underwent 18F-AlF-P16-093 PET/CT and mpMRI examinations at the First Affiliated Hospital of Guangzhou Medical University from August 2023 to March 2024. The entire prostate was divided into 12 regions based on biopsy localization. Imaging evaluations were performed using PET/CT and mpMRI at the lesion level, with biopsy pathology as the gold standard. The correlations between mpMRI scores, PET/CT scores and pathological diagnosis results were evaluated by Phi coefficient analysis. Diagnostic efficacy was assessed by ROC curve analysis. Logistic regression was used to determine the impact of bleeding on image interpretation. Results:18F-AlF-P16-093 PET/CT showed a moderate positive correlation with pathological diagnosis result ( Phi=0.415, P<0.001), which was superior to mpMRI ( Phi=0.338, P<0.001). The diagnostic efficacy of PET single-modality model was superior to mpMRI in all indicators. The combination of 18F-AlF-P16-093 PET/CT with mpMRI significantly improved diagnostic specificity and positive predictive value, with the diagnostic specificity of the PET+ T 2 weighted imaging (WI)+ diffusion WI (DWI) and PET+ T 2WI+ DWI+ apparent diffusion coefficient (ADC) combinations exceeding 90%, and the positive predictive value exceeding 80%. Bleeding did not significantly affect the diagnosis of PCa by mpMRI and PET/CT (odds ratio ( OR): 0.463-0.785, all P>0.05). Conclusion:18F-AlF-P16-093 PET/CT is superior to mpMRI in the detection and diagnostic efficacy of PCa lesions, and the combination of 18F-AlF-P16-093 PET with mpMRI can further improve diagnostic specificity and positive predictive value, which is of guiding significance for targeted prostate biopsy.

Objective:To investigate the efficacy of 99Tc m-pyrophosphate (PYP) SPECT imaging for the differential diagnosis of transthyretin-related cardiac amyloidosis (ATTR-CA) and hypertrophic cardiomyopathy (HCM). Methods:Data of patients who were definitively diagnosed with ATTR-CA (35 patients (28 males, 7 females); age 62.5(58.6, 64.3) years) or HCM (14 patients (13 males, 1 female); age 60.5(57.3, 68.7) years) by extracardiac biopsy and echocardiography in the Second Xiangya Hospital of Central South University between June 2020 and March 2023 were retrospectively analyzed. All patients underwent planar and SPECT imaging 1 h after injection of 370-720 MBq 99Tc m-PYP. Visual scoring was performed (0-1 was negative, 2-3 was positive), and heart-to-contralateral lung uptake ratio (H/CL) was calculated based on planar images. The χ2 test was used to compare the difference in visual scores between ATTR-CA and HCM groups, and the diagnostic efficacy of the visual score was calculated. The H/CL differences between ATTR and HCM groups were compared with Mann-Whitney U test, and the ROC curve was used to analyze the efficacy of H/CL for the differential diagnosis of ATTR-CA and HCM. Results:There were 34 patients with visual scores≥2 and 1 patient with visual score<2 in the ATTR-CA group, 6 patients with visual scores =2 and 8 patients with visual scores <2 in HCM group, and there were significant differences between the 2 groups ( χ2=16.20, P<0.001). The diagnostic sensitivity of the visual score was 97.1%(34/35), and the specificity was 8/14. The H/CL in the ATTR-CA group was significantly higher than that in the HCM group (2.08(1.97, 2.20) vs 1.26 (1.17, 1.35), z=-5.09, P<0.001). The ROC curve analysis suggested that the optimal cut-off value was 1.45 (AUC: 0.980, 95% CI: 0.946-1.000; P<0.001); the sensitivity of H/CL differential diagnosis between HCM and ATTR-CA was 97.1%(34/35), and the specificity was 14/14. Conclusion:99Tc m-PYP SPECT imaging is useful in differentiation of ATTR-CA and HCM, and the optimal cut-off value of H/CL for differential diagnosis of these 2 diseases is 1.45.

Objective This study aims to examine the potential mechanism of Shenfu Yixin Granules on heart failure(HF)based on network pharmacology,molecular docking,and experimental verification.Methods(1)The active components of herbs in Shenfu Yixin Granules were screened and retrieved through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP).PubChem database and Swiss Target Prediction platform were used to predict targets.GeneCards and OMIM databases were used to screen HF-related targets.The intersection of active ingredient targets of Shenfu Yixin Granules and HF-related targets was performed by using Venny 2.1.0 platform to obtain common targets,which were the potential targets for anti-HF effect of Shenfu Yixin Granules.The potential targets were imported into the STRING database to construct a protein-protein interaction(PPI)network and screen the core targets of Shenfu Yixin Granules for the treatment of HF.GO functional and KEGG pathway enrichment analysis of potential targets were carried out by using DAVID database.AutoDock Vina software was used for molecular docking validation of key active ingredients and core targets.(2)SD rats were randomly allocated into sham operation group,model group,Shenfu Yixin Granules(5.28 g·kg-1)group,and positive control group(sacubitril-valsartan,20.8 mg·kg-1),with eight rats in each group.A rat model of HF after myocardial infarction was established by ligating the left anterior descending coronary artery.The rats were subsequently administered orally with the corresponding drugs once daily for a period of four weeks.Cardiac function including left ventricular ejection fraction(LVEF)and left ventricular fraction shortening(LVFS)in rats was assessed by echocardiography.Additionally,the histopathological alterations in rat heart tissue were examined using hematoxylin-eosin(HE)staining and Masson staining.The serum levels of brain natriuretic peptide(BNP),artial natriuretic peptide(ANP),and aldosterone(ALD)were determined by enzyme-linked immunosorbent assay(ELISA).Furthermore,real-time quantitative PCR and Western Blot were employed to detect mRNA and protein expressions of CAV1、F2 and MAPK1 in heart tissue.Results(1)A total of 210 active ingredients and 1 196 targets of Shenfu Yixin Granules,as well as 801 HF-related targets were obtained.Venny 2.1.0 platform was used to acquire 97 potential targets(common targets)of Shenfu Yixin Granules for the treatment of HF.Key active ingredients,such as quercetin,luteolin,arachidonic acid,kaempferol,and tanshinaldehyde were screened by"drugs-active ingredients-disease-targets"network analysis.The core targets including MAPK1、F2、CAV1、EDN1 and GJA1 were identified through PPI network analysis.The potential targets are mainly concentrated in multiple biological processes,namely,the positive regulation of gene expression,cardiac development,and the positive regulation of MAPK cascade,and involve multi key pathways including MAPK signaling pathway,HIF-1 signaling pathway and PI3K/Akt signaling pathway etc.Good binding activities were observed between MAPK1,CAV1,EDN1,F2 and quercetin,luteolin,kaempferol,tanshinaldehyde,as well as MAPK1,F2 and arachidonic acid.(2)Compared with sham operation group,LVEF and LVFS of rats significantly reduced(P＜0.01),heart mass index obviously increased(P＜0.05)in the model group.Myocardial tissue appears obvious pathological damage,and the degree of interstitial fibrosis was serious.The collagen volume fraction of the heart significantly increased(P＜0.01).The levels of serum BNP,ANP and ALD significantly increased(P＜0.01).The mRNA and protein expressions of CAV1、F2 and MAPK1 in heart tissue significantly increased(P＜0.05,P＜0.01).Compared with the model group,LVEF and LVFS of rats obviously increased(P＜0.01),but the decrease in heart mass index was not significant(P＞0.05)in Shenfu Yixin Granules group and positive control group.The pathological damage in myocardial tissues was significantly improved,the degree of interstitial fibrosis was significantly reduced.The collagen volume fraction of the heart significantly decreased(P＜0.01).The levels of serum BNP,ANP and ALD significantly decreased(P＜0.01).The mRNA and protein expressions of CAV1、F2 and MAPK1 in heart tissue significantly decreased(P＜0.05,P＜0.01).Conclusion Shenfu Yixin Granules may improve heart function and myocardial fibrosis in heart failure rats through the interaction between the active ingredients(quercetin,luteolin,arachidonic acid,kaempferol,and tanshinaldehyde)and targets(MAPK1,F2,CAV-1,and EDN1),so as to regulate MAPK signaling pathway and PI3K/Akt signaling pathway.
