One patient with kidney stones was prescribed Paishi granules and diclofenac sodium sustained-release tablets for pain relief in the outpatient setting.That evening,the patient took 1 sachet of Paishi granules and 1 diclofenac sodium sustained-release tablet together.The patient subsequently developed a generalized rash with itching.Liver function indexes of alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(T-BiL),direct bilirubin(D-BiL),and alkaline phosphatase(ALP)were all 2 to 6 times higher than the upper limit of normal.After symptomatico treatment,the patients systemic rash had subsided,and the liver function indicators have returned to normal.

Objective To explore the diagnostic value of hemodynamic and morphological characteristics based on four-dimensional flow magnetic resonance imaging(4D Flow MRI)for unstable saccular intracranial aneurysms(IAs).Methods Seventy-four patients with saccular unruptured intracranial aneurysms(UIAs)who underwent 4D Flow MRI examinations were selected.Morphological and hemodynamic data of the IAs were collected and followed up.According to the follow-up results,patients were divided into stable group and unstable group.Logistic regression analysis was used to identify factors associated with the unstable group,and the diag-nostic performance of the model was evaluated using the receiver operating characteristic(ROC)curves and the area under the curve(AUC).Results The aneurysm diameter,height,width,neck width,and aspect ratio(AR)value in the unstable group were greater than those in the stable group.The wall shear stress(WSS)at the aneurysm neck and the parent artery inflow,as well as the end diastolic velocity(EDV)at the parent artery inflow,were lower in the unstable group than those in the stable group(P＜0.05).Multivariate logistic regression analysis showed that the AR and WSS at the aneurysm neck were independent predictors of unstable IAs(P＜0.05).The combined model of WSS at the aneurysm neck and AR showed an AUC of 0.742[95％confidence interval(CI)0.608-0.875],repre-sented the highest diagnostic performance.Conclusion The hemodynamic characteristics quantified by 4D Flow MRI offer supple-mentary information for risk assessment of IAs.Combining hemodynamic and morphological characteristics is of significant value in identi-fying unstable saccular IAs.

Myocardial fibrosis is a serious cause of heart failure and even sudden cardiac death. However, the mechanisms underlying myocardial ischemia-induced cardiac fibrosis remain unclear. Here, we identified that the expression of sterile alpha and TIR motif containing 1 (SARM1), was increased significantly in the ischemic cardiomyopathy patients, dilated cardiomyopathy patients (GSE116250) and fibrotic heart tissues of mice. Additionally, inhibition or knockdown of SARM1 can improve myocardial fibrosis and cardiac function of myocardial infarction (MI) mice. Moreover, SARM1 fibroblasts-specific knock-in mice had increased deposition of extracellular matrix and impaired cardiac function. Mechanically, elevated expression of SARM1 promotes the deposition of extracellular matrix by directly modulating P4HA1. Notably, by using the Click-iT reaction, we identified that the increased expression of ZDHHC17 promotes the palmitoylation levels of SARM1, thereby accelerating the fibrosis process. Based on the fibrosis-promoting effect of SARM1, we screened several drugs with anti-myocardial fibrosis activity. In conclusion, we have unveiled that palmitoylated SARM1 targeting P4HA1 promotes collagen deposition and myocardial fibrosis. Inhibition of SARM1 is a potential strategy for the treatment of myocardial fibrosis. The sites where SARM1 interacts with P4HA1 and the palmitoylation modification sites of SARM1 may be the active targets for anti-fibrosis drugs.

Objective To investigate the geographical distribution patterns and influencing factors of suitable habitats for the desert medicinal plant Cynomorium songaricum Rupr under current climatic conditions;To provide a basis for its resource conservation and sustainable utilization.Methods The MaxEnt model was used to analyze potential suitable habitats for Cynomorium songaricum Rupr.Geographical Detector model was used to identify key environmental factors affecting habitat suitability.Surface cover data were overlaid to assess the distribution of sandy and Gobi regions within suitable habitats,enabling a quantitative evaluation of actual potential suitable areas.Results Model predictions indicated a total suitable habitat area of approximately 2.98×106 km2,representing 30.99%of China's mainland area.Highly suitable habitats are concentrated in desert and Gobi regions of Gansu,Xinjiang,Inner Mongolia,Qinghai and Ningxia.Among climatic factors,precipitation of the coldest quarter(bio19),solar radiation in August(srad8),and mean temperature of the coldest quarter(bio11)significantly influence Cynomorium songaricum Rupr distribution.The interaction between temperature and solar radiation intensity exhibited the highest explanatory power for habitat distribution patterns(q=0.82).Overlay analysis with surface cover data estimated the actual potential suitable area at approximately 9.70×105 km2,with sandy regions comprising 5.73×105 km2 and Gobi regions 3.98×105 km2.Conclusion By integrating multi-source data and modeling approaches,this study delineates the potential suitable habitats for Cynomorium songaricum Rupr across China and evaluates the spatial distribution characteristics and influencing factors of suitable habitats in Cynomorium songaricum Rupr.These findings offer a foundation for conserving wild Cynomorium songaricum Rupr resources,optimizing ecological planting regions,and promoting sustainable industry development.

OBJECTIVE: To observe the effects of moxibustion at "Xinshu" (BL15) and "Feishu" (BL13) on myocardial transferrin receptor 1 (TfR1), ferroptosis suppressor protein 1 (FSP1), atrial natriuretic peptide (ANP), and typeⅠcollagen myocardial collagen fibers (CollagenⅠ) in rats with chronic heart failure (CHF), and to explore the mechanism of moxibustion for ameliorating myocardial fibrosis and improving cardiac function in CHF. METHODS: Fifty SD rats were randomly divided into a normal group (n=10) and a modeling group (n=40). The CHF model was established in the modeling group by ligating the left anterior descending coronary artery. After successful modeling, the rats were randomly divided into a model group (n=9), a moxibustion group (n=8), a rapamycin (RAPA) group (n=9), and a moxibustion+RAPA group (n=9). In the moxibustion group, moxibustion was delivered at bilateral "Feishu"(BL13) and "Xinshu" (BL15), 15 min at each point in each intervention, once daily, for 4 consecutive weeks. In the RAPA group, RAPA solution was administered intraperitoneally at a dose of 1 mg/kg, once daily for 4 consecutive weeks. In the moxibustion+RAPA group, RAPA solution was administered intraperitoneally after moxibustion. Ejection fraction (EF) and left ventricular fractional shortening (FS) were measured after modeling and intervention. After intervention, morphology of cardiac muscle was observed using HE staining and Masson's trichrome staining. Total iron content in myocardial tissue was detected using a colorimetric method. Western blot and qPCR were adopted to detect the protein and mRNA expression of TfR1, FSP1, ANP, and CollagenⅠ in myocardial tissue. RESULTS: Compared with the normal group, the EF and FS values decreased (P<0.01); necrosis, edema, degeneration, and arrangement disorder were presented in cardiomyocytes; inflammatory cells were obviously infiltrated, the structure of myocardial fibers was disarranged, the collagen fibers were obviously deposited and fibrosis increased (P<0.01); the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue were elevated (P<0.01), while the protein and mRNA expression of FSP1 were reduced (P<0.01) in the model group. Compared with the model group, the moxibustion group showed that EF and FS increased (P<0.01); myocardial cell morphology was improved, and myocardial fibrosis was alleviated (P<0.01); the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue decreased (P<0.01), while the protein and mRNA expression of FSP1 increased (P<0.01, P<0.05). Compared with the model group, the myocardial fibrosis was increased (P<0.05); the total iron content and the protein and mRNA expression of TfR1, ANP, CollagenⅠ in myocardial tissue were increased (P<0.01), while protein and mRNA expression of FSP1 decreased (P<0.01) in the RAPA group. When compared with the RAPA group and the moxibustion + RAPA group, EF and FS were elevated (P<0.01, P<0.05); myocardial cells were improved in morphology, the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue decreased (P<0.01), while protein and mRNA expression of FSP1 increased (P<0.01) in the moxibustion group. In comparison with the moxibustion + RAPA group, the RAPA group showed the decrease in EF and FS (P<0.01), the worsened myocardial fibrosis (P<0.01), the increase in the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue (P<0.01), and the decrease in the protein and mRNA expression of FSP1 (P<0.01). CONCLUSION Moxibustion at "Feishu" (BL13) and "Xinshu" (BL15) can slow down the process of myocardial fibrosis and improve cardiac function in CHF rats. The mechanism of moxibustion may be related to inhibiting ferroptosis through regulating autophagy.

Objective:To observe the impact of a home-based intervention based on video feedback on the social, cognitive and fine motor skills of children with autism spectrum disorder (ASD).Methods:Fifty children with ASD were randomly divided into a control group and an observation group, each of 25. In addition to conventional rehabilitation training, the control group received routine comprehensive family intervention, while the observation group′s family intervention used video feedback. Before and after 6 months, all of the children′s social, cognitive and fine motor skills were assessed using the Psychoeducational Profile instrument (PEP-3), an aberrant behavior checklist (ABC), the Childhood Autism Rating Scale (CARS), an autism treatment evaluation checklist (ATEC) and a neuropsychological development scale (CNDS) for children up to 6 years old.Results:Before the treatment there was no significant difference between the 2 groups in any of the measurements. Afterward, significant improvement was observed in all of the measurements in both groups. After the treatment, however, the experimental group′s average social interaction, cognition and personal self-care scores on the PEP-3 scale, as well as their average fine motor skill, adaptive capacity, language use and personal social ability were all significantly better than the control group′s averages. At the same time, the experimental group′s average ABC, CARS, communication, sensation, social ability and behavior results were significantly better.Conclusions:Video feedback can effectively improve family interventions stimulating the social and cognitive abilities of children with ASD, as well as their fine motor skills.
