OBJECTIVE To focus on the classic NOD-like receptor protein 3 （NLRP3）/Caspase-1/gasdermin D （GSDMD） pyroptosis pathway and explore the mechanism by which Huatan qushi huoxue formula （HQHF） inhibits macrophage pyroptosis to ameliorate metabolic dysfunction-associated steatohepatitis （MASH）. METHODS RAW264.7 cells were divided into 5 groups： Control group （10% blank serum）， Model group [10% blank serum+5 μg/mL lipopolysaccharide （LPS）]， HQHF-L group （2.5% drug-containing serum+7.5% blank serum+5 μg/mL LPS）， HQHF-M group （5% drug-containing serum+5% blank serum+5 μg/mL LPS）， and HQHF-H group （10% drug-containing serum+5 μg/mL LPS）. After 24 h of routine culture post-administration， cells and supernatants were collected for assays. Cell morphology was observed via scanning electron microscopy and phase-contrast microscopy； localization and expression of gasdermin D-N （GSDMD-N） were observed by immunofluorescence. Interleukin-1β （IL-1β） and IL-18 contents in supernatants were detected by ELISA； mRNA and protein expressions of NLRP3， Caspase-1， and GSDMD were measured using real-time PCR and Western blot. RESULTS Compared with the Control group， the Model group showed typical pyroptotic morphology （cell membrane bulging and pore formation）， increased aggregation and fluorescence intensity of GSDMD-N on the cell membrane （ P ＜0.05）， significantly increased the contents of IL-1β and IL-18 in cell supernatants （ P ＜0.05）， and significantly up-regulated mRNA and protein expressions of NLRP3， Caspase-1， and GSDMD in cells （ P ＜0.05）. Compared with the Model group， the HQHF-L， HQHF-M and HQHF-H groups showed improved pyroptotic morphology， reduced membrane localization and significantly weakened fluorescence intensity of GSDMD-N （ P ＜0.05）， significantly decreased the contents of IL-1β and IL-18 in cell supernatants （ P ＜0.05）， and significantly down-regulated mRNA and protein expressions of NLRP3， Caspase-1， and GSDMD in cells （ P ＜0.05）. CONCLUSIONS HQHF inhibits LPS-induced macrophage pyroptosis， and its mechanism of improving MASH may be associated with the suppression of the activation of the classical NLRP3/Caspase-1/GSDMD pyroptosis pathway.

OBJECTIVE: To observe the clinical efficacy of Qihuang needle therapy for autism spectrum disorder (ASD) children with sleep disorder. METHODS: A total of 60 ASD children with sleep disorder were randomly divided into an observation group and a control group, 30 cases in each group. Both groups were treated with structured education intervention, 60 min each time, once a day, 6 times a week. Qihuang needle therapy was applied at Yintang (GV24⁺), Baihui (GV20) and bilateral Jueyinshu (BL14), Xinshu (BL15) in the observation group, multi-direction needling was delivered and without needle retaining. The treatment was given 2 times a week, each treatment was delivered at interval of 2 days at least. Behavioral intervention was adopted in the control group. Treatment for consecutive 12 weeks was required in both groups. Before and after treatment, the scores of children's sleep habits questionnaire (CSHQ), the autism behavior checklist (ABC), the childhood autism rating scale (CARS), and the childhood autism behavior scale (CABS) were observed in the two groups. RESULTS: After treatment, the scores of CSHQ, ABC, CARS and CABS were decreased compared with those before treatment (P<0.01), and the above scores in the observation group were lower than those in the control group (P<0.05). CONCLUSION Qihuang needle therapy can effectively treat ASD with sleep disorder, improve the core symptoms of ASD and the sleep quality.

ObjectiveTo investigate the association between body roundness index （BRI） and the risk of metabolic dysfunction-associated fatty liver disease （MAFLD） based on the National Health and Nutrition Examination Survey （NHANES） database， as well as the clinical value of BRI as a noninvasive tool for risk prediction. MethodsBased on the NHANES data in 2015—2020， the 4 573 individuals were divided into MAFLD group with 2 508 individuals and non-MAFLD group with 2 065 individuals， and BRI was calculated for each individual. In order to ensure data quality and reduce the impact of abnormal values on analytical results， the boxplot method was used to remove abnormal levels of BRI and improve the robustness of data. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. The multivariate Logistic regression model was established to investigate the association between BRI and MAFLD. BRI was divided into four groups based on quantiles， and with the first quantile （Q1） as reference， odds ratio （OR） and 95% confidence interval （CI） were calculated for the other three models. Restricted cubic spline was used to investigate the dose-effect relationship between BRI and MAFLD. The receiver operating characteristic （ROC） curve was plotted and the area under the ROC curve （AUC） was calculated to assess the efficacy of BRI in the diagnosis of MAFLD. The decision curve analysis was used to investigate the potential clinical value of the model in clinical practice. The interaction analysis and the subgroup analysis were performed to investigate the difference in the association between BRI and MAFLD between different populations. The Lasso regression analysis was conducted for the screening and analysis of characteristic variables. ResultsCompared with the non-MAFLD group， the MAFLD group had a significantly higher BRI （Z=36.29， P<0.001）. After adjustment for the variables including age， sex， ethnicity， educational level， the proportion of individuals with poor income， marital status， smoking， hypertension， diabetes， alanine aminotransferase， aspartate aminotransferase， gamma-glutamyl transpeptidase， and high-density lipoprotein cholesterol， the fully adjusted Logistic regression model showed that BRI was significantly positively associated with the risk of MAFLD （OR=2.53， 95%CI： 2.28 — 2.80， P<0.001）. In addition， the highest BRI quartile （Q4） group had a significantly higher risk of MAFLD than the lowest quartile （Q1） group （OR=83.45， 95%CI： 51.87 — 134.26， P<0.001）. The restricted cubic spline analysis further confirmed the significant nonlinear association between BRI and MAFLD （P for nonlinear<0.001）. The interaction analysis and the subgroup analysis showed that the interaction between hypertension and BRI had statistical significance （P for interaction=0.003）， and compared with the individuals without hypertension， the individuals with hypertension had a stronger association between BRI and MAFLD （OR=1.60， 95%CI： 1.23 — 2.08， P<0.001）. The ROC curve analysis showed that the fully adjusted model based on BRI had a strong discriminatory ability in differentiating MAFLD from non-MAFLD， with an AUC of 0.887 （95%CI： 0.877 — 0.896）. The decision curve analysis showed that the fully adjusted model had good net benefits within the risk threshold of 0.10 — 0.75， which was commonly used in clinical practice. The model based on the key variables identified by the Lasso regression analysis had an AUC of 0.882 （95%CI： 0.872 — 0.892）， which confirmed the robustness of the prediction results. ConclusionThere is a significant positive correlation between BRI and the risk of MAFLD， with a stronger association observed in the hypertensive population. As a body index reflecting abdominal obesity and visceral fat accumulation， BRI shows promising application prospects in the risk assessment of MAFLD.

ObjectiveTo investigate the association between serum creatinine/cystatin C ratio （CCR） and nonalcoholic fatty liver disease （NAFLD） based on the NHANES database， and to evaluate the potential significance of CCR as an indicator reflecting the metabolic status of the body. MethodsBased on the data from the NHANES database in 1999‍ ‍—‍ ‍2004， a total of 4 217 participants were enrolled and divided into NAFLD group with 1 726 participants and non-NAFLD group with 2 491 participants. CCR was compared between the two groups， and the association between CCR and NAFLD was analyzed. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. The multivariate logistic regression model was used to investigate the association between CCR and NAFLD； CCR was divided into 4 groups based on quartiles， and odds ratio （OR） and 95% confidence interval （CI） in the regression model was calculated with the first quartile as reference. In addition， the restricted cubic spline analysis was used to investigate whether there was a non-linear relationship between CCR and NAFLD， and interaction items were introduced into the Logistic regression model to perform an interaction analysis. Subgroup analyses were performed based on the stratification of variables to investigate the difference in the association between CCR and NAFLD in different populations. ResultsThe non-NAFLD group had a significantly higher CCR than the NAFLD group （Z=-4.76，P<0.01）. The Logistic regression analysis showed that in model 1 without adjustment of variables， CCR was negatively associated with NAFLD （OR=0.993，95%CI：0.989‍ ‍—‍ ‍0.996，P<0.01）， and in model 3 with adjustment of all variables， CCR was still negatively associated with NAFLD （OR=0.986，95%CI：0.981‍ ‍—‍ ‍0.991，P<0.01）. The analysis of CCR based on quartiles showed a significant association between the increase in CCR and the reduction in the risk of NAFLD. In model 3， compared with the individuals with the lowest quartile of CCR， the individuals with the highest quartile of CCR had a significantly lower risk of NAFLD （OR=0.426，95%CI：0.316‍ ‍—‍ ‍0.574，P<0.01）. Further interaction and subgroup analyses showed that the interaction between CCR and age/sex had a statistical significance （P_interaction<0.01 and P_interaction=0.04）. The subgroup analysis based on age showed a more significant association between CCR and NAFLD in the middle-aged population （≤60 years） （OR=0.982，95%CI：0.976‍ ‍—‍ ‍0.987）， and the subgroup analysis based on sex showed a stronger association between CCR and NAFLD in women （OR=0.979，95%CI：0.972‍ ‍—‍ ‍0.986）. ConclusionThis study shows a significant negative association between CCR and NAFLD， and such association is more significant in middle-aged individuals and women.

Epigenetic mechanisms play a crucial role in the development and progression of nonalcoholic fatty liver disease （NAFLD）， especially among lean individuals. The research on related epigenetic mechanisms has provided new clues and directions for revealing the underlying causes and treatment strategies of NAFLD. This article introduces the role of epigenetics in the development and progression of NAFLD among lean individuals in recent years， analyzes the latest research advances in the epigenetics of NAFLD in this population， and briefly describes the basic concepts of epigenetics， including DNA methylation， histone modifications， and non-coding RNA regulation. This article also discusses how epigenetic alterations impact the pathogenesis， disease progression， and treatment strategies of NAFLD in lean individuals.

The paper reports a 32-year-old female acute myeloid leukemia patient who developed graft-versus-host disease after paternal hematopoietic stem cell transplantation, which subsequently led to renal thrombotic microangiopathy. She subsequently required a kidney transplant from the same donor 5 years later due to renal failure. Considering that both the bone marrow and kidney were from the same donor and the recovery of renal function was favorable, immunosuppressive therapy was discontinued after a short course of anti-rejection treatment, with maintained stable kidney function. This case suggests that under the condition of high chimerism, allogeneic hematopoietic stem cell transplantation and kidney transplantation from the same donor can achieve immune tolerance, potentially improving solid organ transplantation success rate. The findings provide a novel therapeutic approach for solid organ transplantation following allogeneic hematopoietic stem cell transplantation.
