ObjectiveTo investigate the effects of Yiqi Wenyang Huoxue Lishui components on the cardiac function and mitochondrial energy metabolism in the rat model of chronic heart failure （CHF） and explore the underlying mechanism. MethodsThe rat model of CHF was prepared by transverse aortic constriction （TAC）. Eight of the 50 SD rats were randomly selected as the sham group， and the remaining 42 underwent TAC surgery. The 24 SD rats successfully modeled were randomized into model， trimetazidine （6.3 mg·kg^-1）， and Yiqi Wenyang Huoxue Lishui components （60 mg·kg^-1 total saponins of Astragali Radix， 10 mg·kg^-1 total phenolic acids of Salviae Miltiorrhizae Radix et Rhizoma， 190 mg·kg^-1 aqueous extract of Lepidii Semen， and 100 mg·kg^-1 cinnamaldehyde） groups. The rats were administrated with corresponding agents by gavage， and those in the sham and model groups were administrated with the same amount of normal saline at a dose of 10 mL·kg^-1 for 8 weeks. Echocardiography was used to examine the cardiac function in rats. Enzyme-linked immunosorbent assay was employed to determine the serum levels of N-terminal pro-B-type natriuretic peptide （NT-ProBNP）， hypersensitive troponin（cTnI）， creatine kinase （CK）， lactate dehydrogenase （LD）， free fatty acids （FFA）， superoxide dismutase （SOD）， and malondialdehyde （MDA）. The colorimetric assay was employed to measure the levels of adenosine triphosphate （ATP）， adenosine diphosphate （ADP）， and adenosine monophosphate （AMP） in the myocardial tissue. The pathological changes in the myocardial tissue were observed by hematoxylin-eosin staining and Masson staining. The Na⁺-K⁺-ATPase and Ca²⁺-Mg²⁺-ATPase activities in the myocardial tissue were determined by the colorimetric assay. The ultrastructural changes of myocardial mitochondria were observed by transmission electron microscopy. Western blot was employed to determine the protein levels of ATP synthase subunit delta （ATP5D）， glucose transporter 4 （GLUT4）， and carnitine palmitoyltransferase-1 （CPT-1）. The mitochondrial complex assay kits were used to determine the activities of mitochondrial complexes Ⅰ， Ⅱ， Ⅲ， and Ⅳ. ResultsCompared with the sham group， the model group showed a loosening arrangement of cardiac fibers， fracture and necrosis of partial cardiac fibers， inflammatory cells in necrotic areas， massive blue fibrotic tissue in the myocardial interstitium， increased collagen fiber area and myocardial fibrosis， destroyed mitochondria， myofibril disarrangement， sparse myofilaments， and fractured and reduced cristae. In addition， the rats in the model group showed declined ejection fraction （EF） and fractional shortening （FS）， risen left ventricular end-diastolic diameter （LVIDd）， left ventricular end-systolic diameter （LVIDs）， left ventricular end-diastolic posterior wall thickness （LVPWd）， left ventricular end-systolic posterior wall thickness （LVPWs）， left ventricular end-diastolic volume （LVVOLd）， and left ventricular end-systolic volume （LVVOLs）， elevated levels of NT-ProBNP， cTnI， CK， MDA， FFA， and LD， lowered level of SOD， down-regulated protein levels of GLUT4 and CPT-1， decreased activities of Na⁺-K⁺-ATPase， Ca²⁺-Mg²⁺-ATPase， and respiratory complexes Ⅰ-Ⅳ， and declined levels of ATP5D， ATP， ADP， and AMP （P<0.05， P<0.01）. Compared with the model group， the Yiqi Wenyang Huoxue Lishui components and trimetazidine groups showed alleviated pathological damage of the mitochondria and mycardial tissue， risen EF and FS， declined LVIDd， LVIDs， LVPWd， LVPWs， LVVOLd， and LVVOLs， lowered levels of NT-ProBNP， cTnI， CK， MDA， FFA， and LD， elevated level of SOD， up-regulated protein levels of GLUT4 and CPT-1， increased activities of Na⁺-K⁺-ATPase， Ca²⁺-Mg²⁺-ATPase， and respiratory complexes Ⅰ-Ⅳ， and elevated levels of ATP5D， ATP， ADP， and AMP （P<0.05， P<0.01）. ConclusionYiqi Wenyang Huoxue Lishui components can improve the cardiac function， reduce myocardial injury， regulate glucose and lipid metabolism， optimize the utilization of substrates， and alleviate the damage of mitochondrial structure and function， thus improving the energy metabolism of the myocardium in the rat model of CHF.

Objective Taking a tertiary Traditional Chinese Medicine(TCM)hospital in Beijing as an example,it explores the differences in service quality perception among medical providers in Internet-based diagnostic services,aiming to provide robust support for the digital transformation of TCM medical services.Methods A questionnaire survey was conducted among 145 doctors who had diagnostic privileges on the Internet hospital platform of a certain hospital in September 2024.The survey focused on doctors'perceptions and satisfaction differences between online and offline medical service quality.Data processing and analysis were performed using EXCEL and SPSS 26.0 software,including descriptive analysis,reliability and validity tests,and rank-sum tests.Results 66.34%of the doctors recognized the Internet hospital platform established by the hospital,but the average satisfaction score(3.86)was still lower than that of offline outpatient service platforms,which was 4.59.Especially in the three dimensions of diagnosis and treatment,quality assurance,and psychosocial care,the perception of online service quality was significantly lower than that of offline services(P＜0.001).Despite this,82.76%of doctors were still inclined to recommend the internet-based diagnostic model to suitable patients.Conclusion Internet hospitals should establish a refined and intelligent platform system and rigorous service quality control standards to optimize doctors'online consultation processes.Comprehensive training for online consulting doctors should be strengthened.By improving the service quality of medical providers,the integration of online and offline services can be promoted to meet patients'demands for high-quality medical services.

This study retrospectively analyzed 12 patients with transfusion-dependent, non-severe aplastic anemia (TD-NSAA) refractory to cyclosporine A (CsA) , who were treated with lusutrombopag monotherapy. These patients either had a variety of chronic comorbidities or medication-related risks, or they were unresponsive to or intolerant of other thrombopoietin receptor agonists (TPO-RA) . The median treatment duration with lusutrombopag was 4 months (range: 3-11 months) , while the median follow-up period was 8 months (range: 6-11 months) . The overall response (OR) rates at months 3, 6, and the end of follow-up were 50.0%, 58.3%, and 50.0%, respectively, with a median time to OR of 2 months (range: 1-4 months) . Complete response (CR) rates were 8.3%, 16.7%, and 16.7% at the same time points, with a median time to CR of 4 months (range: 2-5 months) . Adverse events were all Grade 1, with an incidence rate of 25.0%. During follow-up, one patient experienced a loss of OR after discontinuing treatment, with a relapse rate of 14.3%; no clonal evolution or mortality was observed. These findings suggest that lusutrombopag is both effective and well-tolerated in CsA-refractory TD-NSAA patients and represents a promising therapeutic option for those with poor treatment tolerability.

Objective To explore the value of deep learning image reconstruction(DLIR)algorithm to improve the quality of low keV monochromatic portal vein images of energy spectrum CT.Methods Fifty patients who underwent enhanced upper abdominal energy spectrum CT scan were selected.Mixed-model adaptive statistical iterative reconstruction-Veo(50%ASIR-V)algorithm and high-deep learning image reconstruction(DLIR-H)algorithm were used to obtain monochromatic images at 40-70 keV(with intervals of 10 keV).The CT and standard deviation(SD)values of the portal vein trunk,left and right branches,and erector spinae muscle were measured in the transverse position,and the signal-to-noise ratio(SNR)and portal vein contrast-to-noise ratio(CNR)were calculated for objective evaluation.The portal vein image quality between the two algorithms and different energy was subjectively scored by two physicians.Results In terms of objective evaluation:compared with 50%ASIR-V,the CNR and SNR of portal vein in monochromatic DLIR-H images at the same keV between 40-70 keV energy levels were increased while the SD value was decreased(P＜0.05),and the CT value was unchanged;there was no statistical difference in the magnitude of change in CNR between the two algorithms at different energy levels(P＞0.05);there was a statistically significant difference in the magnitude of change in SNR and SD value(P＜0.05)and the magnitude of change was the largest at 40 keV;comparison between different energy levels of DLIR-H,the CNR and SD value of 40 keV DLIR-H were the highest(P＜0.05),and there was no significant difference in the SNR(P＞0.05).In terms of subjective evaluation:there was no significant difference between the subjective scores of the two algorithms at the same keV from 40-70 keV(P＞0.05),and the two reconstruction algorithms at 40 keV and 50 keV had the highest subjective scores between different keV.Conclusion The DLIR algorithm can reduce the noise of low keV monochromatic images,improve the image quality of portal vein.

Renal cell carcinoma(RCC)is a malignant tumor that originates from the epithelial cells of the re-nal tubules,comprising 80%to 90%of all malignant renal tumors.With the dual pressures of population growth and ag-ing,both the incidence and mortality rates of RCC are on the rise.PANoptosis is a newly identified form of cell death,con-trolled by the PANoptosome complex,and exhibits characteristics of three programmed cell death pathways,pyroptosis,apoptosis,and necroptosis.Increasing research indicates that the occurrence of PANoptosis is associated with tumor devel-opment,suggesting its potential as a new therapeutic strategy for renal carcinoma.This article reviews the definition of PANoptosis,the structure of the PANoptosome protein complex,and its impact on the PANoptosis process.Additionally,it explores the interactions between PANoptosis,pyroptosis,apoptosis and necroptosis,and their effects on RCC.

Objective:To study the safety and feasibility of transcatheter arterial chemoembolization (TACE) combined with apatinib in the treatment of advanced hilar cholangiocarcinoma.Methods:Clinical data of 41 patients with hilar cholangiocarcinoma admitted to the First Affiliated Hospital of Zhengzhou University from November 2019 to October 2020 were prospectively collected, including 21 males and 20 females, aged (65.1±12.5) years. The drugs used for TACE were albumin paclitaxel and gemcitabine, which were performed once every four to six weeks for no more than six times. Apatinib were adminstered two days after each TACE. The primary endpoint was objective response rate (ORR) and the secondary endpoints were progression-free survival (PFS), overall survival (OS) and adverse events. Patients were followed-up by outpatient, inpatient or telephone review. Survival analysis was performed using the Kaplan-Meier method.Results:Hilar cholangiocarcinoma were confirmed in all 41 patients by pathology. All patients were treated with TACE for at least twice. Twenty-three patients achieved complete remission, 14 stable disease, and four partial remission, with an ORR of 56.1% and a disease control rate of 90.2%. The follow-up duration was (13.3±5.4) months without lost to follow-up. The median PFS was 9.0 months, the median OS was 14.0 months, the 1-year cumulative recurrence-free survival rate was 31.7%, and the 1-year cumulative survival rate was 65.9%. Treatment-related adverse events in this study were predominantly Clavien-Dindo grade 1 or 2, without grade 4 to 5.Conclusion:TACE combined with apatinib treatment could be safe and feasible for advanced hilar cholangiocarcinoma.

Objective To explore the role of cysteine aspartic protease-8(Caspase-8)/gasdermin E(GSDME)pathway in the regulation of macrophage pyroptosis in myocardial infarction(MI)rat model and its possible mechanism.Methods Thirty rats were randomly divided into sham operation group,MI group and Caspase-8 inhibition(Z-IETD-FMK)group,with 10 rats in each group.The cultured rat macrophages RMa-bm were divided into control group,hypoxia group and Z-IETD-FMK group.The pathological changes of myocardial tissue were detected by H&E staining.Masson staining was used to detect myocardial fibrosis.The protein and mRNA levels of Caspase-8 and GSDME in myocardial tissue and Caspase-8,GSDME,NLR family Pyrin domain protein 3(NLRP3),apoptosis-related speck-like protein(ASC)and Caspase-1 in macrophages were detected by RT-qPCR and Western blotting.The levels of IL-1β and IL-18 in macrophages were detected by ELISA.TUNEL staining was used to detect apoptosis of cardiomyocytes and macrophages.Results Compared with the sham operation group,myocardial tissue of rats in MI group was broken and disturbed,inflammatory cell infiltration,a large amount of collagen fiber deposition in the gap,cell apoptosis increased and the expression of Caspase-8,GSDME protein and mRNA in myocardial tissue increased,the differences were statistically significant(t=16.19,27.60;21.18,23.73,all P<0.05).Compared with MI group,Z-IETD-FMK group improved myocardial structural damage,reduced inflammatory cells and collagen deposition,cell apoptosis decreased and decreased Caspase-8,GSDME protein and mRNA expressions in myocardial tissue,with statistical significance(t=20.34,14.56;11.97,24.46,all P<0.05).Compared with the control group,the apoptosis of macrophages in hypoxia group was increased,and the protein and mRNA expressions of Caspase-8,GSDME,NLRP3,ASC,Caspase-1 in macrophages were increased(tprotein=17.53～120.90,tmRNA=18.42～60.30),the contents of IL-1β and IL-18 in macrophages were increased(t=25.88,45.74),and the differences were staistically significant(all P<0.05).Compared with the hypoxia group,the apoptosis of macrophages in Z-IETD-FMK group was decreased,and the protein and mRNA expressions of Caspase-8,GSDME,NLRP3,ASC,Caspase-1 in macrophages were decreased(tprotein=17.08～35.08,tmRNA=11.21～47.96),IL-1β and IL-18 content decreased(t=27.38,25.82),and the differences were staistically significant(all P<0.05),respectively.Conclusion Down-regulating Caspase-8/GSDME pathway can improve myocardial injury and hypoxic macrophage scorch death in MI rats.

The medicinal use of Malvae Semen has a long history. In this paper， by consulting the ancient materia medica， prescription， agronomy， literature and other aspects of the classics， the name， origin， evolution of scientific name， quality， harvesting and processing， functions and indications and others of Malvae Semen were systematically sorted out and verified， so as to provide a basis for the development and utilization of famous classical formulas containing this herb. According to the textual research， Shennong Bencaojing began to use Dongkuizi as the correct name， which was used in the past dynasties， and there were also aliases such as Kuicaizi， Huacai， and Kuizi. Through the original research， it can be seen that Kuicai is the mainstream original plant of Malvae Semen， that is， Malva verticillata var. crispa， the Alcea rosea and M. cathayensis are also used. In modern times， the seeds of Abutilon theophrasti have been passed off as Malvae Semen， while the seeds of M. verticillata var. crispa have rarely been used in medicine. And Abutili Semen has been another medicinal material with different efficacy since the collection of Newly Revised Materia Medica in the Tang dynasty. Since the Ming and Qing dynasties， the cultivation of Kuicai has been decreasing， while A. theophrasti is more common and easy to obtain， and Abutili Semen and Malvae Semen are similar in morphology and confused， which should be corrected. In addition， Malvae Fructus is a Mongolian customary medicinal herb， which is different from the traditional use of seeds in traditional Chinese medicine. Kuicai， as an important vegetable in history， was widely cultivated and gradually shrunk after the Song dynasty， it is now mainly produced in southern provinces. The quality evaluation of Malvae Semen is better for those with dry bodies， full grain， grayish brown color， no mud， and no impurities. The harvesting is generally in the autumn and winter. After drying， it is seeded， sieved peel and impurities， mashed， or slightly stir-fried to yellow-white color with gentle fire. It is sweet， cold and slippery in nature and taste， with the main effects of laxation， diuresis， lactation and elimination of swelling. The efficacy of Abutili Semen is clearing heat and removing toxicity， promoting diuresis and removing nebula， the efficacy is quite different from that of Malvae Semen. Based on the results of textual research， it is suggested that M. verticillata var. crispa should be used as the medicinal source of Malvae Semen in the development of famous classical formulas， the corresponding processing methods should be selected according to the requirements of drug processing in the formulas， while the raw products are recommended to be used if the processing is not specified.
