Objective To investigate the protective effect of hederagenin(HDG)on cisplatin(Cis)-induced acute kidney injury(AKI)in mice and its potential mechanism.Methods 24 male C57BL/6J mice were randomly divided into a control group,AKI model group,HDG low-dose group,and HDG high-dose group,with six mice in each group.AKI model was established by intraperitoneal injection of 20 mg/kg cisplatin(Cis).The HDG low-dose and HDG high-dose groups were given 20,40 mg/kg HDG by intragastric administration,respectively,and samples were collected 3 days later.The kidneys of the mice were collected for hematoxylin-eosin(HE)and periodic-acid-schiff(PAS)staining to evaluate the kidney pathology,and serum was collected to detect changes in serum creatinine(Scr)and blood urea nitrogen(BUN).The expression of p-P65,P65,IL-6,TNF-α,IL-1β,and other inflammatory-related proteins was detected by Western Blot.A TCMK1(renal tubular epithelial cell)inflammatory cell model was established by Cis(200 ng/mL)stimulation in vitro.Blank group,Cis model group,HDG low-dose group,HDG high-dose group,Axin2 overexpression group,HDG+Axin2 overexpression group were set up.In the Axin2-overexpression group,the expression of p-P65,P65,IL-6,TNF-α,IL-1β,Axin2,and AREG was detected among total cell proteins.Results Compared with the control group,AKI model mice exhibited significantly elevated serum creatinine and blood urea nitrogen levels(P<0.05),accompanied by pathological alterations including vacuolar degeneration of renal tubules,inflammatory cell infiltration,and glycogen deposition,and the expression of inflammation-related proteins(p-P65,TNF-α,IL-6,IL-1β)and Axin2 was markedly upregulated in AKI mice(P<0.05).HDG treatment induced a dose-dependent reduction in serum creatinine and blood urea nitrogen levels(high-dose>low-dose,P<0.05),alleviated renal histopathological damage,and concurrently suppressed the expression of these inflammatory mediators and Axin2(P<0.05).HDG was confirmed that dose-dependently inhibited Cis-induced upregulation of Axin2,and inflammatory cytokines in vitro experiments.Transcriptome sequencing revealed that Axin2 overexpression significantly increased amphiregulin(AREG)expression(P<0.05).Mechanistically,HDG reduced p-P65 phosphorylation by suppressing the Axin2/AREG axis(P<0.05),while Axin2 overexpression abolished the protective effects of HDG against Cis-induced renal tubular cell injury.Conclusions HDG protects against renal injury in AKI mice by reducing inflammation through the inhibition of Axin2/AREG axis activation.

Objective To elucidate the molecular mechanisms underlying the effects of Kanggan Mixture(KGM)on key targets in rats with acute lung injury,network pharmacology and in vivo micro-CT experiments were employed.Methods Network pharmacology was utilized to forecast the target genes and principal pathways involved in the intervention of KGM in acute lung injury(ALI).Lipopolysaccharide(LPS)-induced ALI rat models were utilized,and micro-computed tomography(micro-CT)was employed to evaluate the extent of lung injury in vivo.Experiments were conducted to verify the intervention mechanism of KGM on ALI rats.Results The findings revealed that 190 chemical constituents were identified from KGM,and 579 potential targets and 204 pathways associated with KGM's impact on ALI were predicted.The principal components of KGM,such as quercetin,luteolin,kaempferol,betulin,and lupenone,exhibit anti-viral,anti-inflammatory,and immunomodulatory properties by targeting TP53,AKT1,SRC,EP300,and STAT3,and modulating the FoxO signaling pathway,TNF signaling pathway,PI3K-Akt signaling pathway,and MAPK signaling pathway,demonstrating an influence on acute lung injury.Micro-CT results suggest that KGM can improve lung texture enhancement and lung injury in ALI rats,with an increase in end-expiratory lung volume(inspiratory phase-expiratory phase).The HE and W/D ratio results indicate that KGM can improve lung tissue injury and reduce the lung tissue wet/dry weight ratio(P<0.01).Blood cell analysis results show that the anti-inflammatory agent can decrease the WBC(white blood cell count)and N%(neutrophil percentage)in ALI rats'blood(P<0.01),and increase lymphocytes(P<0.05).Real-time quantitative PCR,WES,and immunohistochemistry results suggest that KGM can decrease the mRNA expression,protein distribution,and protein expression levels of TP53,AKT1,SRC,EP300,and STAT3 in lung tissue of ALI rats(P<0.05).Conclusion KGM has a certain intervention effect on acute lung injury,mainly achieved through the core targets STAT3,EP300,SRC,AKT1,and TP53.

Objective To construct a mindfulness-based self-care intervention program for patients with chronic heart failure(CHF)and their caregivers based on binary disease management theory and explore its small-scale application effect.Methods A prospective study was conducted on 100 pairs of CHF patients admitted to our hospital and their caregivers from January 2024 to October 2024.After excluding those with invalid survey data,92 pairs were finally included and randomly divided into an observation group and a control group,each consisting of 46 pairs.The control group received routine nursing care,while the observation group received the mindfulness-based self-care program based on binary disease management theory in addition to routine nursing care.The Hamilton Anxiety Scale(HAMA),Hamilton Depression Scale(HAMD),Self Compassion Scale(SCS),and Mindfulness Attention Awareness Scale(MAAS)were used to compare the anxiety,depression,self-care,and mindfulness levels of patients and caregivers at three time points:pre-intervention(T1),right post-intervention(T2),and one month post-intervention(T3).The Caregiver Positive Perception Scale(PAC)was used to evaluate the caregiver's positive perception at each time point.Results The HAMA and HAMD scores of patients and caregivers in the observation group were lower than those in the control group at T2 and T3,while the SCS scores were signifi-cantly higher(all P<0.05).Repeated-measures analysis of variance showed significant differences in HAMA,The mindfulness-based self-care intervention program based on binary disease management theory effectively reduces negative emotions in patients and caregivers,and improves mindfulness and self-care,showing clinical application potential.

ObjectiveTo investigate the ameliorative effect of Xingpi capsules on functional dyspepsia（FD） and the potential mechanism. MethodsSixty SPF-grade male SD neonatal rats（7 days old） were randomly divided into the normal group（n=12） and the modeling group（n=48）， and the FD model was prepared by iodoacetamide gavage in the modeling group. After the model was successfully prepared， the rats in the modeling group were randomly divided into the model group， the low-dose and high-dose groups of Xingpi capsules（0.135， 0.54 g·kg^-1） and the domperidone group（3 mg·kg^-1）， with 12 rats in each group. Rats in the normal and model groups were gavaged with distilled water， and rats in the rest of the groups were gavaged with the corresponding medicinal solution， once a day for 7 d. The general survival condition of the rats was observed， and the water intake and food intake of the rats were measured， the gastric emptying rate and the small intestinal propulsion rate were measured at the end of the treatment， the pathological damage of the rat duodenum was examined by hematoxylin-eosin（HE） staining， and the expressions of colonic tight junction protein（Occludin） and zonula occludens protein-1（ZO-1） were detected by immunofluorescence. The differentially expressed genes in the duodenal tissues of the model group and the normal group， and the high-dose group of Xingpi capsules and the model group were detected by transcriptome sequencing after the final administration， and Gene Ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） enrichment analyses were carried out. The transcriptomic results were validated by Western blot， immunofluorescence， and real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， and the active ingredients of Xingpi capsules were screened for molecular docking with the key targets. ResultsCompared with the normal group， the general survival condition of rats in the model group was poorer， and the water intake， food intake， gastric emptying rate and small intestinal propulsion rate were all significantly reduced（P<0.05）， inflammatory infiltration was seen in duodenal pathology， and the fluorescence intensities of Occludin and ZO-1 in the colon were significantly reduced（P<0.01）. Compared with the model group， the general survival condition of rats in the high-dose group of Xingpi capsules improved significantly， and the water intake， food intake， gastric emptying rate and small intestinal propulsion rate were all significantly increased（P<0.05）， the duodenal pathology showed a decrease in inflammatory infiltration， and the fluorescence intensities of colonic Occludin and ZO-1 were significantly increased（P<0.01）. Transcriptomic results showed that Xingpi capsules might exert therapeutic effects by regulating the phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt） through the key genes such as Slc5a1， Abhd6. The validation results showed that compared with the normal group， the phosphorylation levels of PI3K and Akt proteins， the protein expression level of interleukin（IL）-1β， and the fluorescence intensities of IL-6 and IL-1β were significantly increased in the model group（P<0.05， P<0.01）， and the mRNA levels of Slc5a1， Abhd6， Mgam， Atp1a1， Slc7a8， Cdr2， Chrm3， Slc5a9 and other key genes were significantly increased（P<0.01）. Compared with the model group， the phosphorylation levels of PI3K and Akt， the protein expression level of IL-1β and the fluorescence intensities of IL-6 and IL-1β in the high-dose group of Xingpi capsules were significantly reduced（P<0.05， P<0.01）， and the mRNA levels of Slc5a1， Abhd6， Mgam， Atp1a1， Slc7a8， Cdr2， Chrm3 and Slc5a9 were significantly reduced（P<0.05）. Weighted gene co-expression network analysis and molecular docking results showed that E-nerolidol and Z-nerolidol in Xingpi capsules were well bound to ABDH6 protein， and linarionoside A， valerosidatum and senkirkine were well bound to Slc5a1 protein. ConclusionXingpi capsules can effectively improve the general survival and gastrointestinal motility of FD rats， its specific mechanism may be related to the inhibition of PI3K/Akt signaling pathway to alleviate the low-grade inflammation of duodenum， and E-nerolidol， Z-nerolidol， linarionoside A， valerosidatum and senkirkine may be its key active ingredients.

Objective:To investigate the diagnostic value of umbilical cord blood lactic acid and base excess for multi-organ dysfunction following neonatal asphyxia.Methods:A retrospective analysis was conducted on the clinical data of 244 patients at high risk for perinatal asphyxia who received treatment at Dongyang People's Hospital from January 2021 to December 2023.Based on the presence of organ dysfunction, the infants were divided into three groups: a single organ dysfunction group (Group A, n = 55), a multi-organ dysfunction group (Group B, n = 16), and a no organ dysfunction group (Group C, n = 173). Lactic acid levels and base excess values were compared among the three groups. Receiver operating characteristic curves were used to validate the predictive value of lactic acid and base excess values for organ dysfunction. Results:There were no statistically significant differences in general data among the three groups ( P > 0.05). In Group B, the lactic acid level was 15.10 (13.85, 16.83) mmol/L, and the base excess value was 9.80 (6.65, 15.18) mmol/L. In Group A, the lactic acid level was 7.70 (6.25, 11.70) mmol/L, and the base excess value was 5.70 (3.85, 9.60) mmol/L. In Group C, the lactic acid level was 6.80 (4.30, 9.00) mmol/L, and the base excess value was 4.00 (3.00, 6.50) mmol/L. The lactic acid level and base excess value in Group B were significantly higher than those in both Group A and Group C. Additionally, the lactic acid level and base excess value in Group A were significantly greater than those in Group C ( t = 2.60, 20.19, 2.95, 1.92, all P < 0.05). Receiver operating characteristic curve analysis revealed that the combined assessment of base excess value and lactic acid level was more effective than evaluating each parameter individually in predicting the presence of organ damage and multiple organ dysfunction syndrome. Additionally, the detection of base excess value was found to be superior to the measurement of lactic acid level. The areas under the curve values for the combined assessment of base excess value and lactic acid level for the presence of organ damage and multiple organ dysfunction syndrome were 0.694 and 0.856, respectively. In comparison, the AUC values for base excess value detection were 0.678 and 0.846, while the AUC values for lactic acid level measurement were 0.633 and 0.797, respectively. Conclusions:Umbilical cord blood lactic acid and base excess are correlated with organ dysfunction following neonatal asphyxia, and both parameters have clinical value in assessing organ damage.
