Lipotoxicity is a pivotal factor that initiates and exacerbates liver injury and is involved in the development of metabolic-associated fatty liver disease (MAFLD). However, there are few reported lipotoxicity inhibitors. Here, we identified a natural anti-lipotoxicity candidate, HN-001, from the marine fungus Aspergillus sp. C1. HN-001 dose- and time- dependently reversed palmitic acid (PA)-induced hepatocyte death. This protection was associated with IRE-1α-mediated XBP-1 splicing inhibition, which resulted in suppression of XBP-1s nuclear translocation and transcriptional regulation. Knockdown of XBP-1s attenuated lipotoxicity, but no additional ameliorative effect of HN-001 on lipotoxicity was observed in XBP-1s knockdown hepatocytes. Notably, the ER stress and lipotoxicity amelioration was associated with PLA2. Both HN-001 and the PLA2 inhibitor MAFP inhibited PLA2 activity, reduced lysophosphatidylcholine (LPC) level, subsequently ameliorated lipotoxicity. In contrast, overexpression of PLA2 caused exacerbation of lipotoxicity and weakened the anti-lipotoxic effects of HN-001. Additionally, HN-001 treatment suppressed the downstream pro-apoptotic JNK pathway. In vivo, chronic administration of HN-001 (i.p.) in mice alleviated all manifestations of MAFLD, including hepatic steatosis, liver injury, inflammation, and fibrogenesis. These effects were correlated with PLA2/IRE-1α/XBP-1s axis and JNK signaling suppression. These data indicate that HN-001 has therapeutic potential for MAFLD because it suppresses lipotoxicity, and provide a natural structural basis for developing anti-MAFLD candidates.

ObjectiveTo explore the impact of autonomic nerve function on motor function in patients with post-stroke depression (PSD) from the perspective of regional homogeneity (ReHo). MethodsFrom January to December, 2020, a total of 60 inpatients and outpatients with cerebral infarction in the Affiliated Brain Hospital of Nanjing Medical University were divided into control group (n = 30) and PSD group (n = 30). Two groups were assessed using Fugl-Meyer Assessment (FMA), modified Barthel Index (MBI) and Hamilton Depression Scale (HAMD). Heart rate variability (HRV) was measured. Ten patients in each group were selected randomly to undergo resting state functional magnetic resonance imaging (rs-fMRI) to calculate ReHo. ResultsAll HRV indices were lower in PSD group than in the control group (|t| > 2.092, P < 0.05). In PSD group, FMA and MBI scores showed positive correlations with 24-hour standard deviation of normal-to-normal R-R intervals (SDNN), the root mean square of successive differences between normal heartbeats over 24 hours (RMSSD), the percentage of differences between adjacent normal R-R intervals over 24 hours that were greater than 50 ms (PNN50), total power (TP), very low frequency power (VLF) and low frequency power (LF) (r > 0.394, P < 0.05), and showed negative correlations with HAMD scores (|r| > 0.919, P < 0.001). HAMD scores in PSD group were negatively correlated with SDNN, RMSSD, PNN50, TP and VLF (|r| > 0.769, P < 0.001). Compared with the control group, the ReHo increased in PSD group in the right rectus gyrus (142 voxels, t = 6.575), the left medial and paracingulate gyri (204 voxels, t = 4.925) (GRF correction, P-Voxel < 0.005,P-Cluster < 0.05); and reduced in the right cerebellum (191 voxels, t = -6.487), the left middle temporal gyrus (140 voxels, t = -5.516), and the left precentral gyrus (119 voxels, t = -4.764) (GRF correction, P-Voxel < 0.005,P-Cluster < 0.05) in PSD group. ConclusionAutonomic nerve function is related to motor dysfunction in patients with PSD. The modulation of emotional, cognitive and motor brain regions by the autonomic nervous system may play a role in influencing the motor function in patients with PSD.

ObjectiveTo construct a quantitative prediction model of three indicators(moisture absorption rate, film thickness and coating weight gain) during the coating process of Vitamin C Yinqiao tablets(VCYT) by near-infrared spectroscopy(NIRS), and to realize the endpoint judgment. MethodReal-time NIRS data of 4 batches of VCYT during the coating process were collected by diffuse reflection method. The coating method employed was the rolling coating method, and the samples were obtained at the spray stage from the coater's sampling port every 10 minutes, and 57 batches of samples(about 1 800 tablets) were collected at various coating times, the tablets were embedded in molten paraffin, cut longitudinally, and observed by stereomicroscope. The film thickness, with a target value of 38 μm, was then measured using Motic Images Advanced 3.2 software. Furthermore, the mositure absorption rate of samples, aiming for a target value of 3%, was determined in accordance with guiding principles for drug hygroscopicity testing in the 2020 edition of Chinese Pharmacopoeia, and 3 samples were randomly selected from each batch(10 tablets per batch), and the coating weight gain was calculated(target value of 4%). Partial least squares regression(PLSR) was used to construct a quantitative model of the 3 coating indicators, and the predicted values of the coating indicators were smoothed using the moving average method and used to determine the coating endpoints. ResultThe prediction determination coefficients(Rp2) for moisture absorption rate, film thickness and coating weight gain were 0.933 4, 0.932 6 and 0.965 9, the root mean square errors of prediction(RMSEP) were 0.163 5%, 1.870 9 μm and 0.240 3%, the relative percent deviations(RPD) were 3.711 0, 2.760 7 and 5.415 8, respectively. The results of the external validation set demonstrated that the real-time predicted values obtained by the models exhibited the same trend as the measured values, and the coating endpoint could be accurately predicted(with a prediction error of less than 7.32 min and a relative error of less than 5.63%). ConclusionThe established NIRS model exhibits excellent predictive performance and can be used for quality control of VCYT during the coating process.

BACKGROUND:Recently,regenerative endodontic therapy is a promising alternative to the maturation of tissue engineering.Inflammatory microenvironment plays a key role in regulating pulp regeneration. OBJECTIVE:To focus on the change in the inflammatory pulp microenvironment,the balance between inflammation and regeneration,and the research advances in tissue-engineered regenerative endodontic therapy within the context of the inflammatory microenvironment to provide a reference for future investigations into regenerative endodontic therapy. METHODS:We conducted a literature search on PubMed and CNKI using search terms"pulp regeneration,inflammation,regenerative endodontic therapy,tissue engineering"in Chinese and English for articles published between 2013 and 2023.The review finally included 61 relevant articles. RESULTS AND CONCLUSION:(1)The changes in the microenvironment of pulpitis involve a complex interplay of cellular and molecular reactions,which,as inflammation progresses,ultimately the microenvironment hinders tissue repair more than facilitates it.(2)Inflammation can promote dental pulp regeneration through stem cell recruitment and activate the complement system,but it can also hinder the regenerative process through immunosuppression and fibrosis.(3)Tissue engineering's three components(stem cells,growth factors,scaffold materials)collaborate to balance inflammation and regeneration,for example,by using interleukin-6 to regulate dental pulp stem cells and foster a regenerative environment.(4)Current research has been largely silent on infection and inflammation issues.The mechanisms underlying changes in the microenvironment of pulpitis are still not fully understood.One promising avenue for improving the clinical applicability of regenerative dental pulp therapy is to achieve precise regulation of the inflammatory-regeneration balance and create a regenerative microenvironment by synergistically leveraging the three elements of tissue engineering.However,this field of investigation still exhibits significant gaps in understanding,necessitating further exploration into innovative strategies for facilitating dental pulp regeneration under inflammation.As such,additional animal experimentation and randomized clinical trials are required to establish a robust foundation for the clinical practice of tissue engineering-based regenerative dental pulp therapy.
