The therapeutic effects of Yueju Pills on depression and cardiovascular diseases have been widely recognized. Previous studies have shown that the drug can significantly improve depressive-like behaviors induced by chronic unpredictable mild stress(CUMS) combined with atherosclerosis(AS). Given the complex pathogenesis of psychocardiac diseases, this study integrated metabolomics and network pharmacology to systematically elucidate the mechanism of Yueju Pills in alleviating depressive symptoms in psychocardiac diseases. The results demonstrate that, after Yueju Pill intervention, the levels of 9 abnormal metabolites in the hippocampus restore to normal ranges, primarily involving key pathways or signaling pathways, including the cyclic adenosine monophosphate(cAMP), mammalian target of rapamycin(mTOR), glycine/serine/threonine metabolism, and aminoacyl-tRNA biosynthesis. In a high-fat diet-induced CUMS ApoE~(-/-) mouse model, Yueju Pills significantly increases adenosine monophosphate(AMP) levels and decreases L-alanine and D-glyceric acid levels in the hippocampus. In conclusion, Yueju Pills exert antidepressant effects by regulating multiple metabolic axes, including glycine/serine/threonine metabolism and the cAMP, mTOR signaling pathways. Network pharmacology predictions reveal that the treatment of CUMS combined with AS by its core active components may be realized through modulating pathways concerning neuroinflammation and synaptic plasticity, including serine/threonine-protein kinase 1(AKT1), mitogen-activated protein kinase 1(MAPK1), and prostaglandin-endoperoxide synthase 2(PTGS2). This study provides a theoretical reference for the clinical application of Yueju Pills in alleviating the depressive symptoms of psychocardiac diseases.

OBJECTIVE: To explore the effect of simvastatin monotherapy or in combination with doxorubicin on diffuse large B-cell lymphoma (DLBCL) cells and its possible molecular mechanisms. METHODS: The differences in the expression levels of genes and proteins related to the mevalonate (MVA) pathway between DLBCL tissues and reactive lymph node hyperplasia tissues were compared via database analysis, as well as their effects on the prognosis. CCK-8 assay was used to detect the effect of simvastatin and doxorubicin on the viability of different subtypes of DLBCL cells, EdU was used to detect cell proliferation, flow cytometry was used to detect apoptosis, and Western blot was used to detect related protein and signaling pathway proteins. RESULTS: The expression levels of MVA pathway-related genes were increased in tumor tissues of DLBCL patients through the TCGA database, and the median overall survival time of DLBCL patients in HMGCR high expression group was shorter (all P < 0.05). Meanwhile, according to The Human Protein Atlas database, HMGCR protein was significantly high expressed in DLBCL tumor tissue compared with normal tissue. The viability of DLBCL cell lines treated with simvastatin or doxorubicin monotherapy was decreased in time- and concentration-dependent manner, and could be further inhibited by simvastatin combined with doxorubicin especially in GCB subtype cell lines. Both simvastatin and doxorubicin could inhibit the proliferation of DLBCL cell lines, and their combination further suppressed dramatically. Both the two drugs promoted apoptosis in DLBCL cell lines, and the apoptosis was further increased after their combination. Compared with monotherapy, the expression of HMGCR protein and apoptosis-related protein Bcl-2 was further decreased but cleaved-caspase3 and Bax increased after combination therapy. Meanwhile, the expression level of phosphorylated proteins in PI3K-Akt pro-survival signaling pathway were decreased especially in GCB subtype cell lines. CONCLUSION HMGCR, the protein associated with cholesterol synthesis pathway, is highly expressed in DLBCL tumor tissues and indicates poor prognosis. Simvastatin, a lipid-lowering drug, combined with doxorubicin can further affect the survival of DLBCL tumor cells at the cellular level.

OBJECTIVE: This cross-sectional study assessed the methodological quality of systematic reviews (SRs) of Chinese herbal medicine (CHM) published in Chinese between Jan 2021 and Sep 2022. METHODS: Chinese language CHM SRs were identified through literature searches across 3 international and 4 Chinese databases. Methodological quality was appraised using A MeaSurement Tool to Assess systematic Reviews 2. Logistic regressions were used to explore associations between bibliographical characteristics and quality. RESULTS: Analyses of methodological quality found that among the 213 sampled SRs, 69.5% were of critically low quality, 30.5% were of low quality, and none achieved high or moderate quality. Common shortcomings included the failure to identify the studies excluded from the analysis, failure to disclose funding sources, and limited evaluation of the potential impact of bias on conclusions. Logistic regressions revealed that SRs led by corresponding authors affiliated with universities or academic institutions tended to be of lower quality than SRs led by authors affiliated with hospitals or clinical facilities. CONCLUSION Recent Chinese language CHM SRs exhibited limited methodological quality, making them unlikely to support the development of clinical practice guidelines. Urgent initiatives are needed to enhance training for researchers, peer-reviewers and editors involved in the preparation and publication of SRs. Adoption of Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines in Chinese language journals is crucial to improve the relevance of SRs for Chinese medicine development. Addressing deficiencies in methodology and reporting is essential for promoting evidence-based practices and informed clinical decisions in Chinese medicine.

Objective To investigate the effects of Chaihuang Yishen Granules on renal fibrosis in unilateral ureteral obstruction(UUO)mice and its underlying mechanisms.Methods Twenty-four 8-week-old male C57BL/6 mice were randomly divided into control group,model group,and low and high dose groups of Chaihuang Yishen Granules(6 in each group).In control group,only right kidney ureter was exposed and dissected.In model group,the UUO animal model was established by UUO.In low and high dose groups,mice were administered intragastrically at doses of 3.8 and 7.6 g/kg of Chaihuang Yishen Granules respectively,following the model group's method to establish the UUO model.After 7 days,the mice were euthanized and renal samples were collected.HE and Masson staining were used to observe pathological changes and fibrosis degree of the kidneys in each group,Sirius red staining was used to observe collagen deposition.The expression levels of α-smooth muscle actin(α-SMA),fibronectin(FN),type Ⅰ collagen(Col-Ⅰ),glycogen synthase kinase 3β(GSK-3β),and β-catenin related proteins were detected using Western blotting.Changes in A33 and GSK-3β,β-catenin mRNA levels were measured by RT-PCR.Additionally,a normal transformed C3H mouse kidney-1(TCMK1)was used as control(normal group);an in vitro fibrosis model was established using TCMK1 stimulated with Transforming Growth Factor-β(TGF-β);and an in vitro drug model was established using TCMK1 treated with serum containing Chaihuang Yishen Granules.A33 was overexpressed in TCMK1 cells using a transfection with an A33 overexpression plasmid,and changes in fibrosis-related indicators and the expression of A33 and GSK-3β,β-catenin mRNA were observed.Results RT-PCR results showed that,compared with control group,A33 level was significantly increased in model group,while it was significantly reduced in both low and high dose groups of Chaihuang Yishen Granules(P＜0.05).Western blotting showed that the expression levels of fibrosis-related factors such as α-SMA,FN,Col-Ⅰ in model group were significantly higher than those in control group(P＜0.05);while compared with model group,the expression levels of α-SMA,FN,Col-Ⅰ in low and high dose groups of Chaihuang Yishen Granules were significantly lower(P＜0.05).HE,Masson,immunohistochemical staining results showed that model group had severe kidney structural damage,significant increase in collagen deposition,and significantly higher expression levels of GSK-3β and β-catenin proteins compared with those in control group(P＜0.01).In contrast,low and high dose groups of Chaihuang Yishen Granules had good kidney structure,significant improvement in kidney damage and fibrosis,and significantly lower expression levels of GSK-3β and β-catenin proteins compared with those in model group(P＜0.05).In vitro experiment results confirmed that,compared with normal group,A33 overexpression promoted the upregulation of fibrosis-related factors in TCMK1 cells,significantly increase the expression of downstream target genes GSK-3β and β-catenin mRNA in the Wnt/β-catenin signaling pathway(P＜0.05),and A33 overexpression reversed the cellular fibrosis changes downregulated by the serum containing Chaihuang Yishen Granules(P＜0.01).Conclusion Chaihuang Yishen Granules significantly improve renal fibrosis in UUO mice by downregulating the A33/Wnt/β-catenin signaling pathway,suggesting that A33 may be a potential therapeutic target for renal fibrosis.

AIM:To investigate the mechanism of chronic stress-induced myocardial injury in atherosclerotic(AS)mice.METHODS:Eight-week-old SPF-grade male ApoE-/-mice and C57BL/6J mice used in this study.The mice received dietary intervention for 10 weeks followed by pathological examination to test the successful AS modeling.After AS establishment,the mice were exposed to chronic unpredictable mild stress(CUMS)for 6 weeks and then divided into five groups:control,CUMS,AS-regular diet(AS-r)+CUMS,AS-high-fat diet(AS-h),and AS-h+CUMS.During CUMS,open-field test and sucrose preference test were performed on mice in all groups.Blood lipids were characterized using an automatic biochemical analyzer.Hematoxylin-eosin(HE)and oil red O staining were performed to evaluate pathological changes in the aortic root.Cardiac function was assessed using echocardiography.The serum concentration of myocardial injury markers and ATP content was detected by ELISA.Transmission electron microscopy was employed to observe the ul-trastructure of myocardial mitochondria.Myocardial mitochondrial oxygen consumption rate was determined using the Oxy-graph-2k high-resolution respiratory energy metabolism analyzer.Western blot was conducted to quantify the expression of B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),and cleaved caspase-3.RESULTS:compared with the Control group,the total distance traveled,the number of entries into the central area,and the sucrose preference rate were significantly decreased in all CUMS groups(P<0.05).All AS groups exhibited varying levels of lipid deposition and endo-thelial damage in the aortic root,along with a significant reduction in cardiac function(P<0.05)and varying degrees of myocardial injury(P<0.05).In the AS-h+CUMS and AS-r+CUMS groups,myocardial mitochondrial structure was signifi-cantly disrupted.ATP content was significantly reduced(P<0.05),and the rates of oxygen consumption associated with mitochondrial respiratory chain complex I,mitochondrial respiratory chain complexes I+II,and the maximum respiratory capacity of the electron transport system were all significantly decreased(P<0.05).Moreover,the protein levels of Bax and cleaved caspase-3 were significantly increased(P<0.05),while that of Bcl-2 protein was significantly decreased(P<0.05).CONCLUSION:Chronic stress triggers mitochondrial non-steady-state load by disrupting myocardial structure and energy metabolism in AS mice,promoting myocardial cell apoptosis and myocardial injury.

ObjectiveTo investigate the effects of maltol aluminum exposure on miR-193a-3p, demethylase AlkB homolog 5 (ALKBH5), phosphatase and tensin homolog deleted on chromosome ten (PTEN) and protein kinase B (AKT), and whether miR-193a-3p is involved in aluminum-induced cognitive impairment by regulating ALKBH5/PTEN/AKT signaling pathway. Methods Specific pathogen-free male SD rats were randomly divided into control group and low-, medium- and high- dose groups according to their body weight, with eight rats in each group. Rats in the low-, medium-, and high- dose groups were intraperitoneally injected with maltol aluminum solution at concentrations of 10.00, 20.00, and 40.00 μmol/kg body weight, respectively, while the rats in control group were given an equal volume of 0.9% sodium chloride solution. Rats were injected for five days every week for three months. After injection, the novel object recognized test was used to assess the learning and memory ability of the rats. The relative expression of miR-193a-3p and B-cell lymphocytoma-2 (Bcl-2), Bcl-2 associated X protein (Bax) and cysteine aspartate protease-3 (Caspase-3) mRNA in rat hippocampus was detected using the real-time quantitative polymerase chain reaction. The relative protein expression of ALKBH5, PTEN, and AKT2 in the rat hippocampus was detected using Western blot. Results The discrimination index and the preference index of the new object recognition test of the rats in high-dose group were lower than those in control group and low-dose group (all P<0.05). The relative expression of miR-193a-3p and Bcl-2 mRNA in the hippocampus of the rats in high-dose group was lower than those in control group and low-dose group (all P<0.05). The relative mRNA expression of Bax in the high-dose group was higher than those in the control group and low-dose group (both P<0.05). The relative mRNA expression of Caspase-3 of the rats in the high-dose group was higher than that in the other three groups (both P<0.05). The relative protein expression of ALKBH5 in the hippocampus of the rats in the high-dose group was lower than that in the control group (P<0.05). The relative expression of PTEN protein was higher than those in the control group and low-dose group (both P<0.05). The relative protein expression of AKT2 was lower than those in the control group and low-dose group (both P<0.05). Conclusion Sub-chronic aluminum exposure can inhibit the expression of miR-193a-3p in the hippocampus of rats, which may disrupt the ALKBH5/PTEN/AKT pathway and affect normal neuronal homeostasis and cellular function. This pathway may play an important role in aluminum-induced cognitive impairment.

RNA editing, an essential post-transcriptional reaction occurring in double-stranded RNA (dsRNA), generates informational diversity in the transcriptome and proteome. In mammals, the main type of RNA editing is the conversion of adenosine to inosine (A-to-I), processed by adenosine deaminases acting on the RNAs (ADARs) family, and interpreted as guanosine during nucleotide base-pairing. It has been reported that millions of nucleotide sites in human transcriptome undergo A-to-I editing events, catalyzed by the primarily responsible enzyme, ADAR1. In hematological malignancies including myeloid/lymphocytic leukemia and multiple myeloma, dysregulation of ADAR1 directly impacts the A-to-I editing states occurring in coding regions, non-coding regions, and immature miRNA precursors. Subsequently, aberrant A-to-I editing states result in altered molecular events, such as protein-coding sequence changes, intron retention, alternative splicing, and miRNA biogenesis inhibition. As a vital factor of the generation and stemness maintenance in leukemia stem cells (LSCs), disordered RNA editing drives the chaos of molecular regulatory network and ultimately promotes the cell proliferation, apoptosis inhibition and drug resistance. At present, novel drugs designed to target RNA editing(e.g., rebecsinib) are under development and have achieved outstanding results in animal experiments. Compared with traditional antitumor drugs, epigenetic antitumor drugs are expected to overcome the shackle of drug resistance and recurrence in hematological malignancies, and provide new treatment options for patients. This review summarized the recent advances in the regulation mechanism of ADAR1-mediated RNA editing events in hematologic malignancies, and further discussed the medical potential and clinical application of ADAR1.

italic>Platycodon grandiflorum (Jacq.) A. DC is one of the most commonly used bulk medicinal herbs. It has important value in the fields of medicine, food and cosmetics, and its market demand is increasing year by year, and it has a good development prospect. In this study, based on 403 distribution records and 8 environmental variables, we used Maxent model to predict the potential distribution of P. grandiflorum under climate change. The results showed that the model simulation effect was the best when the Maxent parameter was FC (feature combination) = LQPH (L: linear features; Q: quadratic features; P: product features; H: hinge features) and RM (regularization multiplier) = 2.1, AUC (area under curve) = 0.901, and the model prediction showed that P. grandiflorum was widely distributed in 28 provinces of China under the current climate conditions, with a suitable area of 2 337 419.98 km². Under the influence of climate change in the future, the area of suitable habitat of P. grandiflorum showed a decreasing trend, and the distribution center as a whole showed a trend of northward and eastward shift. The distribution area of P. grandiflorum in the three main producing areas is affected by climate change, and the overall trend is that the future suitable distribution area of Chifeng in Inner Mongolia increases, while the future suitable distribution area of Zibo in Shandong and Taihe, Bozhou in Anhui decreases or even disappears under the SSP5-8.5 scenario (shared socioeconomic pathways). It is suggested to maintain and protect the ecological environment and germplasm resources of the reserved area suitable for the growth of P. grandiflorum, and increase the cultivation research in the expansion area of P. grandiflorum, so as to lay a foundation for the subsequent expansion of P. grandiflorum planting and to promote the protection and sustainable development of P. grandiflorum resources.

Aim To explore the mechanism of the effect of rosiglitazone(Rsg)on the pancreatic cancer in diabetic mice based on the impact of PPARγ on glu-cose transport and metabolism.Methods A high-fat and high sugar diet combined with STZ was used to construct T2DM model;T2DM mice and normal mice were subcutaneously injected with PANC02 cells to construct a transplanted tumor model.T2DM trans-planted tumor mice and normal transplanted tumor mice were divided into the following groups:Rsg,PPARy inhibitor(PIN-2),rosiglitazone+PPARγ in-hibitor(Rsg+PIN-2),and normal transplanted tumor mice(NDM)and T2DM transplanted tumor mice(DM)were used as control groups,respectively.Tis-sue samples were collected after intervention.Tissue pathological changes were observed by HE staining.The expressions of Ki67 and PCNA proteins were de-tected by immunohistochemistry.Cell apoptosis was detected by TUNEL assay.The expression of PPARγwas detected by immunofluorescence.The expressions of Glucokinase,GLUT2,Nkx6.1,PDX-1RT-PCR were determined by Western blot.Results Rsg could significantly reduce the tumor mass,pathological chan-ges,Ki67 and PCNA expression of transplanted tumors(P＜0.05),increase cell apoptosis and the expression of PPARγ,Glucokinase,GLUT2,Nkx6.1,PDX-1 proteins in NDM and DM mice(P＜0.05).PIN-2 could reverse the indicator changes caused by Rsg in NDM and DM mice.However,compared with NDM mice,the above related indicators of the DM group mice were more sensitive to Rsg and PIN-2.Conclu-sions Compared to non-diabetic pancreatic cancer,rosiglitazone can more sensitively inhibit the prolifera-tion of pancreatic cancer with T2DM,induce apopto-sis,and reprogram the metabolism of pancreatic cancer with T2DM by activating PPA Rγ and altering the ex-pression of glucose and lipid metabolism genes,there-by exerting an anti-cancer effect.
