ObjectiveThis study aims to investigate the therapeutic effects of Wenyang Xiaoyin Prescription （Linggui Zhugan Tang combined with Tingli Dazao Xiefei Tang） on a doxorubicin-induced mouse model of chronic heart failure （CHF）. The multi-targeting action mechanism of the therapy is revealed， based on the arginine vasopressin （AVP）-vasopressin V₂ receptor （V2R）-aquaporin 2 （AQP2） signaling pathway and nuclear transcription factor -κB （NF-κB） pathway mediated by the liver X receptor （LXR） in the heart， brain， and kidney tissue. MethodsCHF mouse models were established by using intraperitoneal injection of doxorubicin and subsequently divided into a blank control group， a model control group， Wenyang Xiaoyin Prescription groups （Linggui Zhugan decoction combined with Tingli Dazao Xiefei decoction） with various doses， a captopril group， and a combination group receiving both Wenyang Xiaoyin prescription （as before） and captopril. Cardiac function was assessed by using color Doppler echocardiography， while the levels of brain natriuretic peptide （BNP）， AVP， and the renin-angiotensin-aldosterone system （RAAS） in the serum were measured via enzyme-linked immunosorbent assay （ELISA）. Pathological changes and ventricular remodeling in ventricular tissues were evaluated through hematoxylin and eosin （HE） and Masson staining， and myocardial cell apoptosis of mice was assessed by using TdT-mediated dUTP Nick-End Labeling （TUNEL） staining. Western blot and real-time polymerase chain reaction （Real-time PCR） were employed to detect the protein and RNA expression levels of LXRα， nuclear factor kappa-light-chain-enhancer of activated B cells （NF-κB）， tumor necrosis factor-α （TNF-α）， inducible nitric oxide synthase （iNOS） in the cardiac tissue， LXRβ， AVP in the hypothalamus， and LXRβ， V2R， and AQP2 in the kidneys. Furthermore， immunohistochemistry was used to quantify AQP2-positive collecting ducts in renal tissues. ResultsThe Wenyang Xiaoyin prescription significantly enhanced cardiac function indicators in CHF mice， reducing levels of BNP， AVP， and RAAS in the serum. It also mitigated myocardial cell damage and fibrosis change. The Wenyang Xiaoyin prescription inhibited the expressions of NF-κB and its downstream targets TNF-α and iNOS and improved myocardial inflammatory response， cell apoptosis， and ventricular remodeling by upregulating the expression of LXRα in cardiac tissues. Concurrently， the Wenyang Xiaoyin prescription elevated LXRβ expression in the kidneys and hypothalamus while downregulating the expression levels of AVP， V2R， and AQP2， as well as water permeability in the collecting ducts， thereby alleviating cardiac load. ConclusionThe intervention of Wenyang Xiaoyin prescription demonstrates a significant therapeutic effect on CHF， and its role involves the multi-target effect mechanism of the AVP/V2R/AQP2 and NF-κB pathways mediated by the nuclear receptor LXR in the heart， brain， and kidney tissue.

As an important part of TCM diagnosis,eye diagnosis is of great significance and value in identifying the symptoms of diseases and predicting the regression of diseases.With the progress of science and technology,the research on"syndrome differentiation by observing the eyes"is gradually converging towards digitalization,standardization and objectification.Based on the theoretical foundation of"syndrome differentiation by observing the eyes",this article reviewed the modern clinical applications of objectifying eye diagnosis from aspects such as observing the scleral vessels,observing fundus signs,and observing eye movement information,and found that modern technological means such as eye diagnostic instrument,eye movement instrument and artificial intelligence algorithms have provided accurate and objective diagnostic bases for TCM syndrome differentiation by observing the eyes to identify the syndrome and have greatly promoted the development of the objectification of eye diagnosis.However,the objective application of eye diagnosis still faces challenges related to technology,data and standardization,calling for further in-depth research and the establishment of unified standards.Exploring the current research status and strategies can provide theoretical references for the objectification of TCM eye diagnosis and the improvement of clinical visual diagnosis accuracy.

Objective To explore the effects of hepatitis B virus genotypes B and C on hepatic stellate cells(HSC)proliferation,cell cycle,and secretion under different alanine aminotransferase(ALT)statuses.Methods A total of 270 patients diagnosed with chronic hepatitis B in the First Hospital of Lanzhou University between January 2023 to December 2023 were selected by stratified random sam-pling.In the group with normal ALT,there were 42 patients with genotype B and 48 patients with genotype C.In the group with ALT ≥ the upper normal limit(UNL)and＜2 times the UNL(2 UNL),there were 48 patients with genotype B and 45 patients with genotype C.In the group with ALT≥2 UNL,there were 45 patients with genotype B and 42 patients with genotype C.Sera from these patients was used as the interfering sera.After HSC were treated with the interfering serum,the proliferation of HSC was detected by the MTT method,the cell cycle was detected by flow cytometry,the mRNA expressions of TGF-β1,Smad3,Smad7,α-SMA,Collagen Ⅰ,and Collagen Ⅲ were detected by real-time PCR,and the expressions of the corresponding proteins were detected by Western blotting.Results When the ALT level was normal,hepatitis B virus genotypes B and C had no obvious effect on HSCs.When the ALT level was abnormal,particularly in the group with ALT ≥ 2 UNL,the virus with genotype C was more likely to promote the proliferation of HSC,reduce the number of cells in the G0/G1 phase,increase the number of cells in the S phase and G2/M phase,enhance the mRNA and protein expressions of TGF-β1,Smad3,Collagen Ⅰ,Collagen Ⅲ,and α-SMA,and decrease the mRNA and protein expressions of Smad7,with significant differences(P＜0.05).Conclusion The effects of hepatitis B virus genotypes B and C on HSC differ varying ALT statuses.During abnormal ALT elevation,genotype C hepatitis B virus demonstrates more pronounced effects on HSC proliferation,cell cycle progression,and secretory function compared to genotype B.

Objective To establish a human luminal breast cancer stem cell(BCSC)model and investigate the inhibitory effects of astragaloside Ⅳ(AS-Ⅳ)on BCSC growth.Methods MCF-7 breast cancer cells were cultured in stem cell-specific medium to induce BCSC formation.The BCSCs were then divided into a blank control group and an AS-Ⅳ treatment group,both groups were given PBS or AS-Ⅳ treatment.Morphological changes were observed after intervention.The therapeutic efficacy of AS-Ⅳ was evaluated using 3D spheroid formation and cell viability assays.Transcriptomic profiling and gene expression analysis were performed to elucidate the underlying mechanisms.Results Compared with the MCF7 breast cancer cells,MCF7 breast cancer stem cell mammospheres exhibited accelerated growth(P＜0.01)and significantly increased expression of the stemness marker ALDH1A1(P＜0.01).Further comparison with the blank control group revealed that astragaloside Ⅳ(AS-Ⅳ)treatment significantly inhibited MCF7 breast cancer stem cell proliferation(P＜0.001)and slowed mammosphere growth(P＜0.01).Transcriptomic analysis demonstrated that differentially expressed genes(DEGs)induced by stem cell modeling and AS-Ⅳ intervention were enriched in the cellular senescence signaling pathway.AS-Ⅳ intervention substantially increased the number of SA-β-gal-positive cells(P＜0.01).RT-PCR analysis confirmed that AS-Ⅳsignificantly upregulated mRNA expression of IL-1α(P＜0.01),P21(P＜0.001),and P53(P＜0.05)in MCF7 breast cancer stem cells.Conclusion Astragaloside Ⅳ suppresses the growth of human luminal breast cancer stem cells by inducing cellular senescence.
