Artificial liver support therapy for liver failure is often complicated by thrombocytopenia， which increases the risk of bleeding. This article systematically elaborates on the pathophysiological role of platelets in liver disease， and systematically analyzes the differential effect of various artificial liver support modalities on platelets， with a focus on key factors such as biocompatibility and anticoagulation strategies. This article also summarizes the clinical management approaches including individualized platelet transfusion and the application of thrombopoietic agents and discusses the value of platelet count as a predictive indicator for treatment safety and efficacy， in order to provide a basis for precise clinical intervention.

Aim To investigate the effect of triptolide(TP)on corticosterone(CORT)-induced depression-like behaviors in mice and explore the antidepressant mechanism of TP based on the CREB/BDNF/TrkB sig-naling pathway.Methods Sixty 8-week-old male C57BL/6J mice were randomly divided into five groups:control group,CORT group,TP groups of low and high doses(10,30 μg·kg-1),and fluoxetine(FLU)group(10 mg·kg-1).Except for the control group,the other groups received subcutaneous injec-tions of CORT for three consecutive weeks to establish the model of depression.During the last two weeks of modeling,normal saline,TP and FLU were adminis-tered via intraperitoneal injection respectively.After the administration,depression-like behaviors in mice were assessed using forced swimming test,tail suspen-sion test,and sucrose preference test.Biochemical methods were used to measure the levels of SOD and MDA in the hippocampus and prefrontal cortex(PFC).Cell apoptosis was detected by TUNEL meth-od.Immunohistochemistry,immunofluorescence,and Western blotting were employed to detect the expres-sion of apoptosis/autophagy-related proteins,synaptic structure markers,and proteins related to the CREB/BDNF/TrkB signaling pathway.Results TP signifi-cantly ameliorated CORT-induced depression-like be-haviors in mice,mainly manifested by reduced immo-bility time in the tail suspension test and forced swim-ming test,and increased sucrose preference rate.TP alleviated CORT-induced oxidative stress by increasing SOD levels and reducing MDA production in brain tis-sue.Additionally,TP also inhibited apoptosis and ex-cessive autophagy of neurons in the hippocampus and prefrontal cortex,maintained synaptic plasticity,and significantly upregulated the expression of p-CREB,BDNF,and TrkB.Conclusions TP exhibits potential antidepressant effect in mice by upregulating the CREB/BDNF/TrkB signaling pathway,reducing oxida-tive stress,inhibiting excessive neuronal apoptosis and autophagy,and improving synaptic plasticity.

Alcoholic liver disease(ALD)is a liver disease caused by long-term heavy drinking and one of the most common causes of liver-related morbidity and mortality.According to Chinese medicine,the development of ALD is mainly related to alcoholism,and the evolution of its pathology is a gradually aggravating process.Wine-heat injures the liver,without obvious organic lesions at the initial stage,and as the disease progresses to different stages,internal dampness appears,dampness depresses and transforms into heat,and Qi stagnation and blood stasis are gradually aggravated,which affects the functions of various internal organs,directly or indirectly,and creates a complex mechanism of crosstalk between the liver and other organs,which leads to the pathological condition of This leads to the pathological state of multi-organ dysfunction.Modern research has found that long-term alcohol abuse not only causes direct damage to the liver,but also leads to progression to end-stage liver disease by altering the intestinal barrier function and intestinal microbial community,and producing kidney damage and cardiac function.This article reviewed recent studies on the interactions between the liver and other organs in light of the Chinese and Western pathogenesis of alcoholic liver disease and the theory of organ crosstalk,and introduces potential strategies for the treatment of alcoholic liver disease,which will provide a reference for the discovery of new therapeutic avenues.

Objective:To explore the effect of early cardiac rehabilitation strategies on functional prognosis in patients with acute coronary syndrome(ACS)who received coronary artery bypass grafting(CABG).Methods:A total of 158 ACS patients who underwent CABG in the First Affiliated Hospital of Xinjiang Medical University between Jan-uary 2022 and December 2023 were included in this randomized control trial.Participants were randomly divided in-to early cardiac rehabilitation group(n=79)and control group(n=79).Patients in the control group received con-ventional nursing measures,while those in the early rehabilitation group received additional early cardiac rehabilita-tion strategies.Both groups were continuously intervened for 1 month.We compared the changes in cardiac function[left ventricular end-diastolic diameter(LVEDd),left ventricular ejection fraction(LVEF)and 6-miniute walk distance(6MWD)],myocardial injury markers[cardiac troponin I(cTnI),N-terminal pro brain natriuretic pep-tide(NT-proBNP)and cystatin C(CysC)],quality of life[China questionnaire of quality of life in patients with cardiovascular diseases(CQQC)score],ability of daily living(ADL)score,and incidence of major adverse cardio-vascular events(MACE)during the intervention period between two groups.Results:Compared to participants in the control group,those in the early rehabilitation group had significantly higher LVEF[(53.31±1.73)％vs.(52.09±1.72)％,P＜0.001],6MWD[(407.60±25.00)m vs.(395.17±19.20)m,P＜0.001],CQQC score[(84.75±8.44)points vs.(75.98±7.60)points,P＜0.001]and ADL score[(88.67±2.58)points vs.(78.87±3.05)points,P＜0.001],and significantly lower LVEDd[(47.02±2.28)mm vs.(52.93±2.57)mm,P＜0.001],cTnI[(0.48±0.04)μg/L vs.(0.52±0.05)μg/L,P＜0.001],NT-proBNP[(213.74±23.54)ng/ml vs.(287.26±41.99)ng/ml,P＜0.001],CysC[(0.87±0.08)mg/L vs.(1.06±0.10)mg/L,P＜0.001]and in-cidence of MACE(9.21％vs.24.32％,P=0.013).Conclusion:Early cardiac rehabilitation strategy may improve cardiac function and prognosis in patients with acute coronary syndrome who received coronary artery bypass grafting.

Objective:To explore the effect of empowerment-authorized health management on the rehabilitation,self-efficacy and quality of life in patients with non-ST-segment elevation acute coronary syndrome(NSTE-ACS)after per-cutaneous coronary intervention(PCI).Methods:This randomized controlled study enrolled 100 NSTE-ACS patients ad-mitted in the First Affiliated Hospital of Xinjiang Medical University between January 2021 and June 2023.Patients were randomly divided into control group(n=50,routine nursing)and intervention group(n=50,empowerment-authorized health management).Both groups were intervened for 6 months.The scores of heart health self-efficacy and self-man-agement(HH-SESM)scale,China questionnaire of quality of life in patients with cardiovascular diseases(CQQC),cardi-ac function indexes,serum levels of N terminal pro brain natriuretic peptide(NT-proBNP)and cardiac troponin I(cTnI),6min walking distance(6MWD),satisfaction and incidence of adverse events were compared between the two groups.Re-sults:Compared to patients in the control group after nursing,those in the intervention group had significant higher HH-SESM total score[(79.34±6.18)points vs.(62.33±6.17)points],CQQC total score[(116.24±7.13)points vs.(83.27±7.11)points],left ventricular ejection fraction(LVEF)[(59.32±4.36)％vs.(51.22±4.63)％],6min walk-ing distance(6MWD)[(363.61±12.51)m vs.(299.13±13.54)m]and satisfaction(86.96％vs.68.09％)(P＜0.05 or＜0.01),and significant lower left ventricular end-systolic diameter(LVESd)[(32.44±3.91)mm vs.(39.25±3.61)mm],left ventricular end-diastolic diameter(LVEDd)[(41.23±4.18)mm vs.(46.17±5.41)mm],NT-proBNP[(6.16±1.58)pg/ml vs.(12.51±3.27)pg/ml]and cTnI[(2.65±0.62)ng/ml vs.(5.60±1.81)ng/ml](P＜0.001 all).The incidence of adverse events in the intervention group(4.35％)was significantly lower than that of control group(19.15％,P=0.027).Conclusion:Empowerment-authorized health management mode was beneficial to the recovery of cardiac function and significantly improved self-efficacy and quality of life in patients with non-ST-segment elevation a-cute coronary syndrome.

The incidence rate of kidney diseases in China has always remained high.At present,the clinical treat-ment mainly focuses on symptomatic treatment to delay the progression of the disease,and there is a lack of eco-nomical and effective treatment methods.MicroRNA plays an important regulatory role in the occurrence and devel-opment of diseases.This study aims to explore the role and regulatory mechanism of miR-142a-3p in adriamycin(ADR)-induced renal tubular epithelial cell(TCMK-1)injury,with a focus on its potential as a therapeutic target for ADR nephropathy.First,cell viability was assessed using the CCK-8 kit,and a mouse renal tubular epithelial cell model induced by ADR was established.Subsequently,alterations in miR-142a-3p and its target gene ATG16L1 mRNA levels were quantified using RT-qPCR.Western blotting was used to detect the protein levels of autophagy marker proteins and pyroptosis marker proteins.Monodansylcadaverin(MDC)staining was performed and the autophagy of cells was detected by flow cytometry.The results showed that the relative expression of miR-142a-3p in TCMK-1 cells induced by ADR was increased and the relative expression of its target gene ATG16L1 was decreased(P＜0.0001).Western blotting results showed that the levels of p62(P＜0.001)and pyroptosis-related proteins(P＜0.001)were increased,while the protein levels of autophagy-related proteins were decreased(P＜0.05).The flow cytometry results showed that there was no difference in the mean fluorescence intensity of autoph-agosomes between the ADR group and the autophagosome inhibitor group(3-MA group)(P＞0.05),indicating that after ADR induction,cell autophagy was inhibited and pyroptosis was enhanced.When the expression of miR-142a-3p was inhibited by transfecting miR-142a-3p inhibitor,the relative expression level of the target gene ATG16L1 was restored(P＜0.001).Western blotting showed that the protein level of p62(P＜0.01)and pyropto-sis-related proteins(P＜0.01)were decreased,and the protein level of autophagy-related proteins was restored(P＜0.001).Flow cytometry results further indicated that cell autophagy was restored(P＜0.0001).In conclusion,ADR targets A TG1 6L1 through miR-142a-3p to reduce the autophagy level of TCMK-1,and simultaneously activates GSDMD-mediated pyroptosis.
