Objective : To investigate the effects of heat shock protein 70 ku protein 1A(HSPA1A) on H9c2 inflammation and apoptotic injury in rat cardiomyocytes under hypoxia, and to analyze its mechanism. Methods: H9c2 cells were treated with normal oxygen(Nor) and hypoxia(Hyp), and the expression of HSPA1A was detected by RT-qPCR and Western blot. Normal H9c2 cells were divided into Nor group(normoxia culture), sh-HSPA1A+Nor group(cells transfected with HSPA1A shRNA, normoxia culture), Hyp group(hypoxia culture), sh-HSPA1A+Hyp group(cells transfected with HSPA1A SHRNA, hypoxia culture), the expression level of HSPA1A in H9c2 cells in each group was detected by RT-qPCR and Western blot, the morphology of H9c2 cells in each group was observed by inverted microscope, and the activity of H9c2 cells in each group was detected by CCK-8, the contents of inflammatory factors tumor necrosis factor-α(TNF-α), interleukin(IL)-6, IL-1β and the activities of myocardial injury markers lactate dehydrogenase(LDH), creatine kinase(CK) in the supernatant of H9c2 cells were detected by ELISA, apoptosis rate of H9c2 cells in each group was detected by Annexin V-FITC/PI double staining, the expression levels of TNF receptor-associated factor 2(TRAF2)/nuclear factor κB(NF-κB) pathway-related proteins in H9c2 cells of each group were detected by Western blot. Results: Compared with Nor group, the relative expression of HSPA1A mRNA and protein in H9c2 cells in Hyp group after hypoxia induction was significantly up-regulated(P<0.05). Compared with Nor group, the number of H9c2 cells in Hyp group significantly decreased, some cells were wrinkled and disordered, the cell activity significantly decreased(P<0.05), the contents of TNF-α, IL-6, IL-1β and the activities of LDH and CK in supernatant significantly increased(P<0.05), the cell apoptosis rate significantly increased(P<0.05), the relative expressions of TRAF2 protein and the phosphorylation level of p65 and inhibitor of nuclear factor κB alpha(IκBα) were significantly up-regulated(P<0.05); compared with Hyp group, the morphology of H9c2 cells in sh-HSPA1A+Hyp group was improved, the cell arrangement was more dense, the cell activity significantly increased(P<0.05), the contents of TNF-α, IL-6 and IL-1β in supernatant decreased, the activities of LDH and CK significantly decreased(P<0.05), the apoptosis rate significantly decreased(P<0.05), the relative expressions of TRAF2 protein and the phosphorylation level of p65 and IκBα were also significantly down-regulated(P<0.05). Conclusion The expression of HSPA1A in rat cardiomyocytes H9c2 is increased by hypoxia, and inhibition of HSPA1A expression can improve the hypoxia-induced inflammatory response of H9c2 cells and reduce apoptosis damage, which may be related to the regulation of TRAF2/NF-κB pathway.

Post-traumatic stress disorder (PTSD) is a psychiatric disorder caused by traumatic past experiences, rooted in the neurocircuits of fear memory formation. Memory processes include encoding, storing, and recalling to forgetting, suggesting the potential to erase fear memories through timely interventions. Conventional strategies such as medications or electroconvulsive therapy often fail to provide permanent relief and come with significant side-effects. This review explores how fear memory may be erased, particularly focusing on the mnemonic phases of reconsolidation and extinction. Reconsolidation strengthens memory, while extinction weakens it. Interfering with memory reconsolidation could diminish the fear response. Alternatively, the extinction of acquired memory could reduce the fear memory response. This review summarizes experimental animal models of PTSD, examines the nature and epidemiology of reconsolidation to extinction, and discusses current behavioral therapy aimed at transforming fear memories to treat PTSD. In sum, understanding how fear memory updates holds significant promise for PTSD treatment.

Background::Pulmonary embolism (PE) is a severe and acute cardiovascular syndrome with high mortality among patients with autoimmune inflammatory rheumatic diseases (AIIRDs). Accurate prediction and timely intervention play a pivotal role in enhancing survival rates. However, there is a notable scarcity of practical early prediction and risk assessment systems of PE in patients with AIIRD.Methods::In the training cohort, 60 AIIRD with PE cases and 180 age-, gender-, and disease-matched AIIRD non-PE cases were identified from 7254 AIIRD cases in Tongji Hospital from 2014 to 2022. Univariable logistic regression (LR) and least absolute shrinkage and selection operator (LASSO) were used to select the clinical features for further training with machine learning (ML) methods, including random forest (RF), support vector machines (SVM), neural network (NN), logistic regression (LR), gradient boosted decision tree (GBDT), classification and regression trees (CART), and C5.0 models. The performances of these models were subsequently validated using a multicenter validation cohort.Results::In the training cohort, 24 and 13 clinical features were selected by univariable LR and LASSO strategies, respectively. The five ML models (RF, SVM, NN, LR, and GBDT) showed promising performances, with an area under the receiver operating characteristic (ROC) curve (AUC) of 0.962-1.000 in the training cohort and 0.969-0.999 in the validation cohort. CART and C5.0 models achieved AUCs of 0.850 and 0.932, respectively, in the training cohort. Using D-dimer as a pre-screening index, the refined C5.0 model achieved an AUC exceeding 0.948 in the training cohort and an AUC above 0.925 in the validation cohort. These results markedly outperformed the use of D-dimer levels alone.Conclusion::ML-based models are proven to be precise for predicting the onset of PE in patients with AIIRD exhibiting clinical suspicion of PE.Trial Registration::Chictr.org.cn: ChiCTR2200059599.

Based on the theory of "mutual interference of clear and turbid Qi" in Huangdi Neijing（《黄帝内经》）， this study explored the pathogenesis of spleen and stomach diseases and the therapeutic effects of Banxia Xiexintang on them. It suggested that "mutual interference of clear and turbid Qi" represents a pathological state of Yin and Yang disturbance and imbalance in Qi circulation due to the mixture of clear and turbid Qi， which can elucidate the pathogenesis of spleen and stomach diseases. According to this theory， the pathogenesis of spleen and stomach diseases was summarized as Qi disorder in spleen and stomach， disharmony between Ying Qi and Wei Qi， and conflict between cold and heat. Banxia Xiexintang， as a crucial prescription for treating spleen and stomach diseases， achieves its therapeutic effects by dispersing stagnation with pungent flavor， descending adverse Qi with bitterness， regulating Ying Qi and Wei Qi， and harmonizing cold and heat. By regulating Qi circulation， balancing internal and external factors， and addressing deficiency and excess， it can rectify the pathological state of "mutual interference of clear and turbid Qi" of spleen and stomach diseases. Modern research reveals that Banxia Xiexintang can modulate gastrointestinal motility， restore mucosal immune barrier function of the digestive system， and exhibit optimal therapeutic effects when combined with both cold-cool and warm-hot medicines， aligning with its therapeutic role under the theory of "mutual interference of clear and turbid Qi". By delving into the essence of the "mutual interference of clear and turbid Qi" theory and exploring the pathogenesis of spleen and stomach diseases and the therapeutic effects of Banxia Xiexintang based on this theory， this study further elucidated the inherent connection between spleen and stomach diseases and the "mutual interference of clear and turbid Qi" theory， offering insights and theoretical references for the clinical diagnosis and treatment of spleen and stomach diseases.
