The innate immune system detects cellular stressors and microbial infections, activating programmed cell death (PCD) pathways to eliminate intracellular pathogens and maintain homeostasis. Among these pathways, pyroptosis, apoptosis, and necroptosis represent the most characteristic forms of PCD. Although initially regarded as mechanistically distinct, emerging research has revealed significant crosstalk among their signaling cascades. Consequently, the concept of PANoptosis has been proposed—an inflammatory cell death pathway driven by caspases and receptor-interacting protein kinases (RIPKs), and regulated by the PANoptosome, which integrates key features of pyroptosis, apoptosis, and necroptosis. The core mechanism of PANoptosis involves the assembly and activation of the PANoptosome, a macromolecular complex composed of three structural components: sensor proteins, adaptor proteins, and effector proteins. Sensors detect upstream stimuli and transmit signals downstream, recruiting critical molecules via adaptors to form a molecular scaffold. This scaffold activates effectors, triggering intracellular signaling cascades that culminate in PANoptosis. The PANoptosome is regulated by upstream molecules such as interferon regulatory factor 1 (IRF1), transforming growth factor beta-activated kinase 1 (TAK1), and adenosine deaminase acting on RNA 1 (ADAR1), which function as molecular switches to control PANoptosis. Targeting these switches represents a promising therapeutic strategy. Furthermore, PANoptosis is influenced by organelle functions, including those of the mitochondria, endoplasmic reticulum, and lysosomes, highlighting organelle-targeted interventions as effective regulatory approaches. Cardiovascular diseases (CVDs), the leading global cause of morbidity and mortality, are profoundly impacted by PCD. Extensive crosstalk among multiple cell death pathways in CVDs suggests a complex regulatory network. As a novel cell death modality bridging pyroptosis, apoptosis, and necroptosis, PANoptosis offers fresh insights into the complexity of cell death and provides innovative strategies for CVD treatment. This review summarizes current evidence linking PANoptosis to various CVDs, including myocardial ischemia/reperfusion injury, myocardial infarction, heart failure, arrhythmogenic cardiomyopathy, sepsis-induced cardiomyopathy, cardiotoxic injury, atherosclerosis, abdominal aortic aneurysm, thoracic aortic aneurysm and dissection, and vascular toxic injury, thereby providing critical clinical insights into CVD pathophysiology. However, the current understanding of PANoptosis in CVDs remains incomplete. First, while PANoptosis in cardiomyocytes and vascular smooth muscle cells has been implicated in CVD pathogenesis, its role in other cell types—such as vascular endothelial cells and immune cells (e.g., macrophages)—warrants further investigation. Second, although pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) are known to activate the PANoptosome in infectious diseases, the stimuli driving PANoptosis in CVDs remain poorly defined. Additionally, methodological challenges persist in identifying PANoptosome assembly in CVDs and in establishing reliable PANoptosis models. Beyond the diseases discussed, PANoptosis may also play a role in viral myocarditis and diabetic cardiomyopathy, necessitating further exploration. In conclusion, elucidating the role of PANoptosis in CVDs opens new avenues for drug development. Targeting this pathway could yield transformative therapies, addressing unmet clinical needs in cardiovascular medicine.

Objective: For patients with atrial fibrillation (AF) complicated with acute coronary syndrome (ACS), both anticoagulant and antiplatelet therapy should be applied, but the use of anticoagulation therapy is still poor in these patients in China. The purpose of this study was to explore the status and adherence of antithrombotic therapy in AF patients with ACS and the impact on 1 year clinical outcomes. Methods: Patients with AF hospitalized for ACS were retrospectively included from 6 tertiary hospitals in China between July 2015 and December 2020. According to the use of anticoagulant drugs at discharge, patients were divided into two groups: anticoagulant treatment group and non-anticoagulant treatment group. Logistic regression model was used to analyze the main factors influencing the use of anticoagulant drugs in patients with atrial fibrillation complicated with ACS. Major adverse cardiac events (MACEs) were defined as all-cause death, non-fatal myocardial infarction or coronary revascularization, and ischemic stroke and Bleeding Academic Research Consortium (BARC) 3 bleeding events were also collected at 1 year after discharge. After propensity score matching, Cox proportional hazards models and Kaplan-Meier analysis were used to evaluate the effect of anticoagulant treatment and non-anticoagulant treatment on 1-year prognosis. The patients were divided into different groups according to whether anticoagulation was performed at discharge and follow-up, and the sensitivity of the results was analyzed. Results: A total of 664 patients were enrolled, and 273 (41.1%) were treated with anticoagulant therapy, of whom 84 (30.8%) received triple antithrombotic therapy, 91 (33.3%) received double antithrombotic therapy (single antiplatelet combined with anticoagulant), and 98 (35.9%) received single anticoagulant therapy. Three hundred and ninety-one (58.9%) patients were treated with antiplatelet therapy, including 253 (64.7%) with dual antiplatelet therapy and 138 (35.3%) with single antiplatelet therapy. After 1∶1 propensity score matching between the anticoagulant group and the non-anticoagulant group, a total of 218 pairs were matched. Multivariate logistic regression analysis showed that history of diabetes, HAS-BLED score≥3, and percutaneous coronary intervention were predictors of the absence of anticoagulant therapy, while history of ischemic stroke and persistent atrial fibrillation were predictors of anticoagulant therapy. At 1-year follow-up, 218 patients (79.9%) in the anticoagulant group continued to receive anticoagulant therapy, and 333 patients (85.2%) in the antiplatelet group continued to receive antiplatelet therapy. At 1-year follow-up, 36 MACEs events (13.2%) occurred in the anticoagulant group, and 81 MACEs events (20.7%) in the non-anticoagulant group. HR values and confidence intervals were calculated by Cox proportional risk model. Patients in the non-anticoagulant group faced a higher risk of MACEs (HR=1.802, 95%CI 1.112-2.921, P=0.017), and the risk of bleeding events was similar between the two group (HR=0.825,95%CI 0.397-1.715, P=0.607). Conclusions: History of diabetes, HAS-BLED score≥3, and percutaneous coronary intervention are independent factors for the absence of anticoagulant therapy in patients with AF complicated with ACS. The incidence of MACEs, death and myocardial infarction is lower in the anticoagulant group, and the incidence of bleeding events is similar between the two groups. The risk of bleeding and ischemia/thrombosis should be dynamically assessed during follow-up and antithrombotic regiments should be adjusted accordingly.

The incidence of liver disease is increasing year by year. Due to the complex predisposing factors and unclear pathogenesis of liver diseases, the cure rate is still not ideal, so it is urgent to clarify its mechanism to find more effective therapeutic targets and drugs. Long non-coding RNA (lncRNA), as a non-coding RNA with a length of more than 200 nt, is a research hotspot in liver diseases in recent years. Focusing on the main signal transduction pathways in liver diseases, this review mainly summarizes the latest research progress of lncRNA in regulating liver disease-related signaling pathways, and elaborates that lncRNAs participate in various physiological processes such as cell proliferation, apoptosis, invasion, and migration by regulating key signaling pathways in liver diseases, thereby promoting the occurrence and development of liver diseases. This review provides new ideas for studying the mechanism of liver diseases, and new directions for finding new targets and biomarkers for the treatment of liver diseases.

OBJECTIVE: To investigate the clinical manifestations pathologic features, treatment options and prognosis of patients with bone lymphoma. METHODS: The clinical characteristics, pathologic features, treatment and prognosis of 34 BL patients diagnosed by histopathologic method or/and PET-CT and treated in first hospital of peking university from January 2004 to April 2018 were analyzed retrospectively. RESULTS: The median age of 34 BL patients was 56 years old, the male and female ratio was 1.43∶1 (24 /10). Among 34 patients, the patients with primary bone lymphoma(PBL) were 8 cases, the patients with secondary bone lymphoma(SBL) was 26 cases, the PBL and SBL ratio was 0.31∶1. Bone lymphoma lacks typical systemic symptoms, and its onset began mostly from bone pain and pathologic bone fracture. The most frequent pathological type of bone lymphoma in our study was diffuse large B-cell lymphoma (DLBCL), accounting for 55.88%. At present, the conventional treatment for bone lymphoma includes chemotherapy, or chemotherapy combined with radiotherapy and surgery, as well as hematopoietic stem cell transplantation. The average and median OS time of BL patients were 349 years and 3 years respectively, meanwhile the OS rate for three years and two years were 56.25% and 78.16%, respectively. Factors that affect survival of BL patients were PBL and SBL classification, pathological type, blood LDH level, and treatment methods. CONCLUSION Bone lymphoma is usually concealed onset，an adequate and adequate combination therapy can improve the survival rate and transplantation therapy plays an important role. Primary bone lymphoma is rare, the prognosis of patients with primary bone lymphoma is good, whereas the prognosis of patients with secondary bone lymphoma is poor.

Objective: To investigate the cause of massive hemoptysis in critical patients, and to evaluate the effect of bronchial artery embolization (BAE) on critical patients with massive hemoptysis. Methods: A retrospective controlled analysis was conducted. The clinical data of 35 patients with life-threatening massive hemoptysis admitted to intensive care unit (ICU) of the First Hospital Affiliated to Guangzhou Medical University from January 2009 to December 2017 were analyzed. The patients were divided into BAE and non-BAE group according to whether receiving BAE or not. BAE patients were subdivided into subgroups: hemoptysis after ventilation and hemoptysis before ventilation subgroups, as well as survival and non-survival subgroups. The etiology of all massive hemoptysis was analyzed. The gender, age, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, amount of hemoptysis, whether presence of pleural thickening in chest CT, the length of ICU stay, total length of hospital stay, the duration of mechanical ventilation (MV), clinical effective and prognostic indicators of patients were recorded. The correlation between variables was analyzed by Spearman correlation analysis. Results: All 35 patients were enrolled in the finally analysis. The main cause of critical patients with massive hemoptysis was fungal infection [37.1% (13/35)], followed by pneumonia and abnormal coagulation [17.1% (6/35)], bronchiectasis [11.4% (4/35)], tumor [8.6% (3/35)], etc. In all 35 patients, 27 were treated with BAE and 8 were treated without BAE. There was no difference in gender, age, the length of ICU stay, total length of hospital stay, the duration of MV, amount of hemoptysis, APACHEⅡ score, whether use antiplatelet agents or anticoagulants, or whether presence of pleural thickening in chest CT between the two groups. The rate of hemoptysis remission in BAE group was significantly higher than that of non-BAE group [92.6% (25/27) vs. 25.0% (2/8), P < 0.01], but there was no statistically significant difference in hospital survival as compared with that of non-BAE group [48.1% (13/27) vs. 25.0% (2/8), P > 0.05]. Subgroup analysis showed that 64.3% (9/14) of patients with hemoptysis after ventilation was caused by pulmonary fungal infection, which was significantly higher than those with hemoptysis before ventilation [15.4% (2/13), P = 0.018]. Compared with hemoptysis after ventilation group, the length of ICU stay and the duration of MV in hemoptysis before ventilation group were significantly shortened [the length of ICU stay (days): 12.0 (14.0) vs. 30.0 (81.8), the duration of MV (days): 10.0 (16.0) vs. 25.0 (68.3)], the patients using antiplatelet drugs or anticoagulant drugs was decreased significantly (case: 1 vs. 9, all P < 0.05). However, there was no statistically significant difference in gender, age, total length of hospital stay, amount of hemoptysis, APACHEⅡ score, whether presence of pleural thickening in chest CT, the rate of hemoptysis remission, the incidence of secondary BAE or hospital survival rate between the two groups. Compared with the survival subgroup (n = 13), more patients in the non-survival subgroup (n = 14) were treated with antiplatelet or anticoagulants (P < 0.05); and Spearman correlation analysis showed that the survival of the patients with BAE was negatively correlated with the use of antiplatelet or anticoagulants (r = -0.432, P = 0.024). There was no significant difference in the gender, age, the length of ICU day, total length of hospitalization, duration of MV, estimated hemoptysis, APACHE Ⅱ score, or the proportion of pleural thickening between the two groups. Conclusions The study indicated that the etiology of massive hemoptysis in critical patients was complicated. Fungal infection was the main cause in patients with hemoptysis after ventilation. BAE was effective in the control of massive hemoptysis in ICU, but it was not ideal for patients with abnormal coagulation function or abnormal platelet count or platelet dysfunction from antiplatelet or anticoagulant drugs, the overall survival rate was still low.

Along with the increase in the prevalence of lipid metabolism disorders,in vitro research on the adipocytes has been a hot topic in recent years. 3T3-L1 preadipocyte line is one of the most commonly used cell line for establishing adipocytes models. However,for 3T3-L1 cell lines,the traditional method,known also as the "Cocktail" method,have disadvantages including low transformation rate and heterogeneous conversion. Therefore,many studies aimed to improving the induction method by changing the time of inducers or adding other new drugs have been performed(known as the improved method). The present study was to summarize the progress of the traditional methods and the improved methods for inducing 3T3-L1 cell lines to mature adipocytes.

The essence of endogenous turbidity in Chinese medicine (CM) is different from cream, fat, phlegm, retention, damp, toxicity, and stasis. Along with the development of modern scientific technologies and biology, researches on the essence of endogenous turbidity should keep pace with the time. Its material bases should be defined and new connotation endowed at the microscopic level. The essence of turbidity lies in abnormal functions of zang-fu organs. Sugar, fat, protein, and other nutrient substances cannot be properly decomposed, but into semi-finished products or intermediate metabolites. They are inactive and cannot participate in normal material syntheses and decomposition. They cannot be transformed to energy metabolism, but also cannot be synthesized as executive functioning of active proteins. If they cannot be degraded by autophagy-lysosome or ubiquitin-prosome into glucose, fatty acids, amino acids, and other basic nutrients to be used again, they will accumulate inside the human body and become endogenous turbidity. Therefore, endogenous turbidity is different from final metabolites such as urea, carbon dioxide, etc., which can transform vital qi. How to improve the function of zang-fu organs, enhance its degradation by autophagy-lysosome or ubiquitin-prosome is of great significance in normal operating of zang-fu organs and preventing the emergence and progress of related diseases.

The paper is aimed to search more natural plant antioxidants and further research and develop new medicinal plant resources in Guizhou. The Guizhou special miao medicine "bod zangd dak" was extracted with 60% ethanol. The antioxidant activity of the different polarity components separated from the extract was tested by DPPH method with ascorbic acid as positive control. The results showed that the IC50 of the different polarity components was as following: ascorbic acid (0.033 4 g x L(-1)) < ethyl acetate components (0.052 3 g x L(-1)) < total tannins components (0.054 9 g x L(-1)) < 60% ethanol extraction components (0.076 7 g x L(-1)) < butanol extraction components (0.110 g x L(-1)) < water-soluble polysaccharides components (0.168 g x L(-1)) < water extraction components (0.174 g x L(-1)) < water components after extraction (0.226 g x L(-1)) < total polysaccharides components (0.645 g x L(-1)). It is concluded that the different polarity components have different free radical scavenging activity and that provides a scientific basis for further search of the active ingredients and the activive mechanism.

ObjectiveTo explore the effect of prone position ventilation (PPV) on respiratory mechanics and prognosis in patients with acute respiratory distress syndrome (ARDS) concurrent with interstitial lung disease (ILD). Methods The data of 36 severe ARDS patients admitted to Department of Critical Care Medicine of the First Affiliated Hospital of Guangzhou Medical University from February 2013 to January 2015, were retrospectively analyzed. They were then divided into two groups according to the presence of ILD or not. The changes in respiratory mechanics and oxygenation indexes were compared before and after PPV treatment in all the patients. Kaplan-Meier method was applied to draw the 60-day survival curves of both groups.Results There were 17 cases with ILD among these 36 severe ARDS patients.① No significant difference was found in baseline data between ILD group and non-ILD group.② Respiratory mechanics and oxygenation pre-PPV and post-PPV: compared with pre-PPV, oxygenation index (PaO2/FiO2, mmHg, 1 mmHg = 0.133 kPa) post-PPV was significantly increased in both groups [ILD group : 132.0 (93.5, 172.0) vs. 118.7 (92.0, 147.8); non-ILD group: 126.1 (100.9, 170.0) vs. 109.2 (89.0, 135.0), bothP< 0.05]. Compared with pre-PPV, positive end-expiratory pressure (PEEP, cmH2O,1 cmH2O = 0.098kPa) post-PPV was significantly higher in ILD group [10.0 (10.0, 12.0) vs. 10.0 (9.2, 12.0),P< 0.05], and respiratory rate (RR, times/min) was significantly lower in non-ILD group [24.5 (22.0, 27.0) vs. 25.5 (22.8, 28.0),P< 0.05]. The compliance of the respiratory system (Crs, mL/cmH2O) post-PPV in non-ILD group was significantly lower than that of the ILD group [19.7 (16.1, 28.6) vs. 23.0 (19.0, 29.7),P< 0.05].③ Respiratory mechanics and oxygenation pre-PPV and post-PPV in total: after all the PPV therapy, PaO2/FiO2 (mmHg) was significantly increased in non-ILD group [135.0 (86.0, 200.0) vs. 97.4 (69.2, 127.5), P< 0.05], PaO2/FiO2 after all the PPV therapy in non-ILD group was also higher than that in ILD group [135.0 (86.0, 200.0) vs. 78.7 (59.3, 114.9),P< 0.05]. No significant difference in Crs (mL/cmH2O) before PPV treatment was found between non-ILD and ILD groups [24.3 (15.9, 48.9) vs. 18.9 (12.7, 27.3),P> 0.05], and Crs was lower after PPV treatment in both groups, but without significant difference [non-ILD group: 22.7 (15.2, 27.1) vs. 24.3 (15.9, 48.9); ILD group: 16.2 (12.8, 25.6) vs. 18.9 (12.7, 27.3), bothP> 0.05].④ The 60-day mortality in ILD group was significantly higher than that in non-ILD group [88.2% (15/17) vs. 57.9% (11/19),P = 0.047). It was shown by Kaplan-Meier curves that 60-day survival patients in ILD group was significantly lower than those in non-ILD group (χ2 = 5.658,P = 0.017). Conclusions PPV can improve oxygenation in severe ARDS. Compared with non-ILD group, though the compliance of respiratory system in ILD group is increased during PPV, long-term effect is better in non-ILD group.
