Objective To investigate the risk factors associated with mortality in patients undergoing surgical treatment for myocardial infarction complicated by ventricular septal rupture, and to establish a prediction model. Methods A retrospective analysis was conducted on clinical data of patients who underwent surgical treatment of myocardial infarction with ventricular septal rupture at Beijing Anzhen Hospital from 2008 to 2022. Patients were followed up and divided into a survival group and a death group based on perioperative and follow-up outcomes. Univariate analysis was performed for all variables, followed by least absolute shrinkage and selection operator (LASSO) regression to screen risk factors affecting postoperative mortality. A Cox regression model was constructed and a Nomogram was developed. Results A total of 83 surgical patients were included, comprising 49 males and 34 females, with a mean age of (64.4±7.7) years. There were 13 perioperative deaths, and among the 70 surviving patients, 6 additional deaths occurred during follow-up. Consequently, 64 patients were assigned to the survival group and 19 to the death group. Univariate analysis revealed statistically significant differences between groups in age, culprit vessel patency status, intra-aortic balloon pump use, Killip classification, time from myocardial infarction to surgery, and time from perforation to surgery (all P<0.05). LASSO regression identified three independent predictors: age [HR=1.092, 95%CI (1.005, 1.187), P=0.039], Killip classification [HR=2.024, 95%CI (1.009, 4.059), P=0.047], and culprit vessel patency [HR=0.110, 95%CI (0.014, 0.869), P=0.036]. The Nomogram based on these variables demonstrated good discriminative ability, with area under the receiver operating characteristic curve of 0.907 at 1 month and 0.876 at 1 year postoperatively. Follow-up revealed cumulative survival rates of 78.2%, 78.2%, 74.6%, and 74.6% at 2, 5, 8, and 10 years postoperatively for all patients, and 92.7%, 92.7%, 88.5%, and 88.5% for perioperative survivors. Conclusion Patients with myocardial infarction complicated by ventricular septal rupture demonstrate favorable mid-to-long-term prognosis after surgical repair. Age, Killip classification, and culprit vessel patency are independent predictors of postoperative mortality, and the established prediction model shows satisfactory prognostic performance.

The regulatory processes in developmental biology research are significantly influenced by long non-coding RNAs (lncRNAs). However, the dynamics of lncRNA expression during human tooth development remain poorly understood. In this research, we examined the lncRNAs present in the dental epithelium (DE) and dental mesenchyme (DM) at the late bud, cap, and early bell stages of human fetal tooth development through bulk RNA sequencing. Developmental regulators co-expressed with neighboring lncRNAs were significantly enriched in odontogenesis. Specific lncRNAs expressed in the DE and DM, such as PANCR, MIR205HG, DLX6-AS1, and DNM3OS, were identified through a combination of bulk RNA sequencing and single-cell analysis. Further subcluster analysis revealed lncRNAs specifically expressed in important regions of the tooth germ, such as the inner enamel epithelium and coronal dental papilla (CDP). Functionally, we demonstrated that CDP-specific DLX6-AS1 enhanced odontoblastic differentiation in human tooth germ mesenchymal cells and dental pulp stem cells. These findings suggest that lncRNAs could serve as valuable cell markers for tooth development and potential therapeutic targets for tooth regeneration.

Extensive epigenetic reprogramming involves in memory CD8+ T-cell differentiation. The elaborate epigenetic rewiring underlying the heterogeneous functional states of CD8+ T cells remains hidden. Here, we profile single-cell chromatin accessibility and map enhancer-promoter interactomes to characterize the differentiation trajectory of memory CD8+ T cells. We reveal that under distinct epigenetic regulations, the early activated CD8+ T cells divergently originated for short-lived effector and memory precursor effector cells. We also uncover a defined epigenetic rewiring leading to the conversion from effector memory to central memory cells during memory formation. Additionally, we illustrate chromatin regulatory mechanisms underlying long-lasting versus transient transcription regulation during memory differentiation. Finally, we confirm the essential roles of Sox4 and Nrf2 in developing memory precursor effector and effector memory cells, respectively, and validate cell state-specific enhancers in regulating Il7r using CRISPR-Cas9. Our data pave the way for understanding the mechanism underlying epigenetic memory formation in CD8+ T-cell differentiation.

Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

OBJECTIVE: To investigate the association between long-term glycemic control and cerebral infarction risk in patients with diabetes through a large-scale cohort study. METHODS: This prospective, community-based cohort study included 12,054 patients with diabetes. From 2006 to 2012, 38,272 fasting blood glucose (FBG) measurements were obtained from these participants. FBG trajectory patterns were generated using latent mixture modelling. Cox proportional hazards models were applied to assess the subsequent risk of cerebral infarction associated with different FBG trajectory patterns. RESULTS: At baseline, the mean age of the participants was 55.2 years. Four distinct FBG trajectories were identified based on FBG concentrations and their changes over the 6-year follow-up period. After a median follow-up of 6.9 years, 786 cerebral infarction events were recorded. Different trajectory patterns were associated with significantly varied outcome risks (Log-Rank P < 0.001). Compared with the low-stability group, Hazard Ratio ( HR) adjusted for potential confounders were 1.37 for the moderate-increasing group, 1.23 for the elevated-decreasing group, and 2.08 for the elevated-stable group. CONCLUSION Sustained high FBG levels were found to play a critical role in the development of ischemic stroke among patients with diabetes. Controlling FBG levels may reduce the risk of cerebral infarction.

OBJECTIVE: The study aim was to investigate the effects of exposure to multiple environmental organic pollutants on cardiopulmonary health with a focus on the potential mediating role of oxidative stress. METHODS: A repeated-measures randomized crossover study involving healthy college students in Beijing was conducted. Biological samples, including morning urine and venous blood, were collected to measure concentrations of 29 typical organic pollutants, including hydroxy polycyclic aromatic hydrocarbons (OH-PAHs), bisphenol A and its substitutes, phthalates and their metabolites, parabens, and five biomarkers of oxidative stress. Health assessments included blood pressure measurements and lung function indicators. RESULTS: Urinary concentrations of 2-hydroxyphenanthrene (2-OH-PHE) ( β = 4.35% [95% confidence interval ( CI): 0.85%, 7.97%]), 3-hydroxyphenanthrene ( β = 3.44% [95% CI: 0.19%, 6.79%]), and 4-hydroxyphenanthrene (4-OH-PHE) ( β = 5.78% [95% CI: 1.27%, 10.5%]) were significantly and positively associated with systolic blood pressure. Exposures to 1-hydroxypyrene (1-OH-PYR) ( β = 3.05% [95% CI: -4.66%, -1.41%]), 2-OH-PHE ( β = 2.68% [95% CI: -4%, -1.34%]), and 4-OH-PHE ( β = 3% [95% CI: -4.68%, -1.29%]) were negatively associated with the ratio of forced expiratory volume in the first second to forced vital capacity. These findings highlight the adverse effects of exposure to multiple pollutants on cardiopulmonary health. Biomarkers of oxidative stress, including 8-hydroxy-2'-deoxyguanosine and extracellular superoxide dismutase, mediated the effects of multiple OH-PAHs on blood pressure and lung function. CONCLUSION Exposure to multiple organic pollutants can adversely affect cardiopulmonary health. Oxidative stress is a key mediator of the effects of OH-PAHs on blood pressure and lung function.

A second-order calibration method combined with excitation-emission matrix(EEM)fluorescence spectroscopy was presented for simultaneous quantitative analysis of two anti-hypertensive drugs,metolazone(MET)and valsartan(VAL),in human serum and urine,and the quantitative results were compared with the results obtained by zero-and first-order calibration methods.The results indicated that the methods based on zero-and first-order calibration were inadequate for accurately quantifying the components of interest in cases where severe spectral overlap and unknown interferences coexisted.However,it was possible to obtain satisfactory results with the second-order calibration method based on alternating normalization-weighted error(ANWE)algorithm because of its strong"mathematical separation",even when the fluorescence spectra of the target analytes and unknown interferents considerably overlapped.Correlation coefficients for both analytes were greater than 0.99,with mean recoveries of 104.9%±5.7%and 107.8%±9.2%for MET and VAL in human serum,and 103.7%±8.9%and 94.7%±3.8%in human urine,respectively.In addition,the sensitivity,selectivity,limit of detection,limit of quantification,repeatability,and reproducibility of the proposed second-order calibration method were thoroughly examined.All results indicated that the established method was capable of achieving simultaneous and accurate quantification of MET and VAL in human body fluids,which was expected to be applied to analysis of both drugs in clinical settings.

Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

Objective:To explore the cardioprotective effects of icariin (ICA) against radiation-induced cardiac disease (RICD) in C57BL/6 mice.Methods:A total of 48 female C57BL/6J mice aged 6-8 weeks were randomly divided into three groups: the control group (CON), the irradiation group (IR), and the irradiation combined with icariin group (IR+ ICA), with 16 mice in each group. The IR and IR+ ICA groups received a single cardiac irradiation at a dose of 30 Gy, while the CON group received no radiation treatment. The IR+ ICA group was treated with ICA (70 mg·kg -1·d -1) two weeks before irradiation until the end of the experiment through intragastric administration. In contrast, the CON and IR groups were treated with an equal volume of vehicle solution (0.5% sodium carboxymethyl cellulose, NaCMC) via intragastric administration. The mice′s mental status, food intake, body weight, and survival rates were monitored during the experiment. At two weeks post-irradiation, the venous blood of the mice was collected and serum was separated for the enzyme-linked immunosorbent assays (ELISA) of creatine kinase MB isoenzyme (CK-MB) and cardiac troponin T (cTnT/TNNT2). At 12 weeks post-irradiation, the cardiac function of the mice was assessed using echocardiography. After the mice were euthanized under anesthesia, the histopathological changes and fibrosis degree of their myocardial tissues were assessed using hematoxylin and eosin (HE) and Masson′s trichrome staining, followed by the calculation of collagen volume fraction (CVF). The differential gene expression of brain natriuretic peptide (BNP), transforming growth factor-β (TGF-β), and interleukin-6 (IL-6) in the cardiac tissues of the mice was detected using real-time reverse transcription-polymerase chain reaction (RT-PCR). Apoptosis-related proteins and proteins associated with the phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) pathway were determined using Western blotting. The survival curves of the mice were plotted using Kaplan-Meier, and the survival differences of the mice among various groups were compared using the log-rank test. Results:After irradiation, the mice in the IR group showed lethargy, as well as decreased food intake and activity, while these symptoms in the IR+ ICA group were significantly alleviated. At two weeks post-irradiation, the CK-MB and cTnT levels of the IR group were significantly elevated compared with the CON group ( t = 5.28, 8.89, P < 0.01). At 12 weeks post-irradiation, the mice in the IR group exhibited significantly decreased body weight ( t = 2.47, P < 0.05) and decreased survival rates ( HR = 8.25, 95% CI: 1.157-58.770, P < 0.05) compared with the CON group. Echocardiography revealed that the IR group featured decreased left ventricular ejection fraction (EF), decreased fractional shortening (FS), and increased left ventricular end-diastolic diameter (LVDD) compared with the CON group ( t = 7.02, 4.45, P < 0.05). Histopathological examination revealed that the IR group suffered from cardiomyocyte edema, disordered arrangement, and increased fibrosis, with an elevated CVF. The IR group exhibited significantly upregulated gene expression of BNP, TGF-β, and IL-6 in cardiac tissues compared with the CON group ( t = 4.23, 6.39, 4.61, P < 0.05). After-irradiation, the IR group exhibited upregulated apoptosis-related proteins Cleaved Caspase-3 and Bax ( t = 6.29, 9.54, P < 0.05), decreased Bcl-2 expression ( t = 8.20, P < 0.001), and decreased phosphorylation levels of PI3K and Akt ( t = 6.47, 3.42, P < 0.001). The symptoms of the mice were partially ameliorated after treatment with ICA. Specifically, the mice in the IR+ ICA group exhibited higher body weight ( t = 5.13, P < 0.001) and significantly higher survival rates ( HR = 0.121, 95% CI: 0.017-0.864, P < 0.05) than the IR group. Compared to the IR group, the IR+ ICA group showed elevated cardiac function indicators EF and FS( t = 3.23, 3.05, P < 0.05), and reduced LVDD ( t = 3.02, P < 0.05). The histopathological analysis revealed mitigated edema and disordered arrangement of cardiomyocytes in the IR+ ICA group. Furthermore, the IR+ ICA group exhibited significantly lower BNP, TGF-β, and IL-6 expression levels than the IR group ( t = 2.83, 4.15, 2.96, P < 0.05). The expression of apoptosis-related proteins Cleaved Caspase-3 and Bax was lower ( t = 3.23, 3.24, P < 0.05), Bcl-2 expression was higher ( t = 5.92, P < 0.001), and restored phosphorylation levels of PI3K and Akt ( t = 2.89, 8.35, P < 0.001). Conclusions:Icariin has protective effects against the RICD. It alleviates cardiomyocyte apoptosis possibly by upregulating the phosphorylation levels of PI3K and Akt.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.
