    Abstract Abstract Background The distribution of ACE2 and accessory proteases (ANAD17 and CTSL) in cardiovascular tissue and the host cell receptor binding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are crucial to understanding the virus’s cell invasion, which may play a significant role in determining the viral tropism and its clinical manifestations. Methods We conducted a comprehensive analysis of the cell type-specific expression of ACE2, ADAM17, and CTSL in myocardial tissue from 10 patients using RNA sequencing. Our study included a meta-analysis of 2 heart single-cell RNA-sequencing studies with a total of 90,024 cells from 250 heart samples of 10 individuals. We used co-expression analysis to locate specific cell types that SARS-CoV-2 may invade. Results Our results revealed cell-type specific associations between male gender and the expression levels of ACE2, ADAM17, and CTSL, including pericytes and fibroblasts. AGT, CALM3, PCSK5, NRP1, and LMAN were identified as potential accessory proteases that might facilitate viral invasion. Enrichment analysis highlighted the extracellular matrix interaction pathway, adherent plaque pathway, vascular smooth muscle contraction inflammatory response, and oxidative stress as potential immune pathways involved in viral infection, providing potential molecular targets for therapeutic intervention. We also found specific high expression of IFITM3 and AGT in pericytes and differences in the IFN-II signaling pathway and PAR signaling pathway in fibroblasts from different cardiovascular comorbidities. Conclusions Our data indicated possible high-risk groups for COVID-19 and provided emerging avenues for future investigations of its pathogenesis. Trial registration (Not applicable).

    Abstract Introduction: Cinnabar (96% HgS) is included in Chinese medicines, including Hua-Feng-Dan. We have shown the protective effects of Hua-Feng-Dan against LPS plus rotenone-induced neurotoxicity in rats and against LPS plus MPTP-induced neuroinflammation in mice by modulation of gut microbiota. However, the effects of HgS-containing Hua-Feng-Dan in comparison to HgS and HgCl2 are unknown. Methods: Mice were given orally with Hua-Feng-Dan at clinical doses (0.6 and 1.5 g/kg), approximate Hg as HgS or HgCl2 for 7 days. Intestinal histology and Hg accumulation were examined. Bacterial DNA from the colon contents was extracted and subjected to DNA sequencing and qPCR verification with 16S rRNA probes. Results: Hua-Feng-Dan and HgS did not affect animal body weight gain, intestinal histology, nor produce overt intestinal Hg accumulation (2-fold). In contrast, HgCl2 reduced body weight gain, produced spotted mild inflammation, and produced 20-fold Hg accumulation in the duodenum. Operational taxonomic unit (OTU) from DNA sequencing showed that at phyla levels, HgS increased Firmicutes and decreased Bacteroidetes, while HgCl2 produced opposite effects; at the family levels, Hua-Feng-Dan increased Streptococcaceae and Dehalobacteriaceae, HgS had similar effects; at the genus levels, Hua-Feng-Dan and HgS increased Streptococcaceae__garvieae and Paraprevotellaceae__Prevotella, while HgCl2 increased Dehalobacteriaceae__Dehalobacterium and Odoribacteraceae__Odoribacter. HgS also increased Verrucomicrobiaceae__Akkermansia and produced many other alterations. Discussion: Cinnabar-containing Hua-Feng-Dan had minimal effects on animal health, gut histology and Hg accumulation but produced modulations of gut microbiota. Effects of Hua-Feng-Dan on gut microbiota were different from HgS and HgCl2.

    Abstract Objective. Acute respiratory distress syndrome (ARDS) is defined as the acute onset of noncardiogenic edema and subsequent gas-exchange impairment due to a severe inflammatory process known as cytokine storm. Xuebijing injection (hereinafter referred to as Xuebijing) is a patent drug that was used to treat ARDS or severe pneumonia (SP) in China. However, its efficacy and mechanism of actions remain unclear. In this study, we used meta-analysis and network pharmacology to assess these traits of Xuebijing. Methods. We searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang databases for randomized controlled trials (RCTs) that evaluated Xuebijing therapy for ARDS or SP. The outcomes were total mortality, intensive care unit (ICU) stay time, and TNF-α and IL-6 levels. We performed a meta-analysis using RevMan 5.3 software. The putative targets, top 10 proteins, and possible pathway of Xuebinjing on ARDS were analyzed by network pharmacology. TNF-α and IL-6 were further docked with the six main active components of Xuebinjing using AutoDock 4.2.6 and PyMol 1.5.0.3 software. Results. Fifteen RCTs involving 2778 patients (13 ARDS and 2 SP) were included. Compared with the control, Xuebijing treatment significantly reduced the mortality rate (risk ratio, 0.64 (95% credible interval (CrI), 0.54–0.77)), reduced the ICU stay time (mean difference (MD), -4.51 (95% CrI, -4.97–-4.06)), reduced the TNF-α ((MD), -1.23 (95% CrI, -1.38–-1.08)) and IL-6 ((MD), -1.15 (95% CrI, -1.52–-0.78)) levels. The 56 putative targets, top 10 proteins (MAPK1 (mitogen-activated protein kinase 1), MAPK8 (mitogen-activated protein kinase 8), RELA (transcription factor p65), NFKB1 (nuclear factor NF-kappa-B p105 subunit), JUN (transcription factor AP-1), SRC (proto-oncogene tyrosine-protein kinase), TNF (tumor necrosis factor), HRAS (GTPase HRas), IL6 (interleukin-6), and APP (amyloid-beta A4 protein)), and possible pathways (Ret tyrosine kinase, IL2-mediated signaling events, CD4+/CD8+ T cell-related ...

    Abstract Coronary heart disease (CHD) is the worldwide leading cause for cardiovascular death. Panax notoginseng saponin (PNS), which is the main bioactive compound of panax notoginseng, has been generally accepted to exert a remarkable effect on CHD for a long time. However, to reveal the underlying treatment target and corresponding mechanism of PNS against CHD is still a substantial challenge. In this work, the targets and mechanism of PNS against CHD were successfully achieved by pharmacology-based prediction and experimental verification. 36 common targets were screened out through integrating the gene expression profile of CHD and the chemical-protein data of PNS. Then, two key nodes were further selected for verification by experiment after analyzing GO function, KEGG pathway, coexpression, and topology analysis. Results showed that PNS has protected the human umbilical vein endothelial cells from H2O2-induced oxidative stress by inhibiting early cell apoptosis via upregulating VEGFA mRNA expression. Therefore, our research has successfully pointed out one treatment target and apoptotic inhibition caused by PNS with method of integrating bioinformatics prediction and experimental verification, which has partially explained the pharmacological mechanism of PNS against CHD.

    Abstract Objective: To evaluate the effects of Yisui Shengxue Granules on expressions of alpha-hemoglobin stabilizing protein (AHSP) and erythroid transcription factor GATA-1 mRNAs in bone marrow of patients with β-thalassemia, and to explore its possible molecular mechanism.Methods: Twelve patients with β-thalassemia intermedia were treated with Yisui Shengxue Granules for three months. The blood indexes including hemoglobin (Hb), RBC, fetal hemoglobin (HbF) and reticulated corpuscles (Ret) were examined before and after treatment. Total RNA was extracted from bone marrow karyocyte in 8 patients selected from these 12 patients before and after treatment, and the expression levels of the AHSP and GATA-1 mRNAs were measured by real-time PCR. Results: Yisui Shengxue Granules could not only obviously improve the clinical symptoms of patients with β-thalassemia intermedia, but also obviously increased the contents of Hb, RBC, HbF and Ret (P<0.05, or P<0.01). The expression levels of AHSP and GATA-1 mRNAs also significantly increased after treatment as compared with those before treatment (P<0.05, or P<0.01). Conclusion: The results revealed that one of the possible molecular mechanism of the effects caused by Yisui Shengxue Granules is that it can up-regulate the expression levels of AHSP and erythroid transcription factor GATA-1 mRNAs, enhance the protein synthesis of AHSP which can bind the relative excess free alpha-globin, prevent the formation of alpha -globin-cytotoxic precipitates in red blood cells and decrease the hemolysis.

    Abstract Objective: To observe the effects of Yiqi Huoxue Formula (YQHXF), a compound Chinese herbal medicine, on transforming growth factor-β (TGF-β)/smad signal transduction pathway and connective tissue growth factor (CTGF) in rats with renal interstitial fibrosisMethods: Unilateral ureteral obstruction (UUO) rat model was established and the rats were randomly divided into 5 groups: untreated group, high-, medium-, and low-dose YQHXF groups and fosinopril sodium group. Another group with sham operation was set as control. All rats were administered with corresponding drugs for 3 weeks. After the last administration, each rat was sacrificed and weighed and the serum was separated for creatinine (Cr) and blood urea nitrogen (BUN) detection. Kidneys of the rats were taken out, and mRNA and protein expressions of TGF-β, smad2, smad7 and CTGF were measured with real-time fluorescent quantitative reverse transcription-polymerase chain reaction and Western blotting respectively; fibrosis of the kidney tissue was observed with hematoxylin-eosin (HE) staining and Masson trichrome staining.Results: Compared with sham-operation group, Cr and BUN in serum of UUO groups were increased, while high-dose YQHXF treatment decreased the UUO-induced increase of Cr and BUN levels. HE staining and Masson staining results showed that the renal tubular epithelial cells in untreated group got atrophied; lumens of renal tubules expanded; fibroplastic proliferation and inflammatory cell infiltration were observed in renal interstitium; the number of glomerulus decreased and collagen increased significantly compared with sham-operation group. In the high- and medium-dose YQHXF groups and fosinopril sodium group, the histopathological changes of inflammatory cell infiltration, fibroplastic proliferation, expansion of lumens of renal tubules was improved as compared with the untreated group. The mRNA and protein expressions of TGF-β, smad2 and CTGF in untreated group were higher than those in sham-operation group (P<0.05), and the mRNA and protein expressions of smad7 in untreated group were lower than those in the sham-operation group (P<0.05). Compared with untreated group, high- and medium-dose of YQHXF significantly down-regulated the mRNA and protein expressions of TGF-β, smad2 and CTGF (P<0.01, P<0.05), and up-regulated the mRNA and protein expressions of smad7 (P<0.01, P<0.05).Conclusions: The mRNA expression of CTGF in UUO rats may be regulated by TGF-β/smad signaling transduction pathway. YQHXF might inhibit the expression of CTGF through down-regulation of TGF-β and smad2 and up-regulation of smad7, thus inhibiting the progression of renal interstitial fibrosis.

    Abstract Diabetes mellitus is accompanied by hormonal and neurochemical changes that can be associated with anxiety and depression. Both diabetes and depression negatively interact, in that depression leads to poor metabolic control and hyperglycemia exacerbates depression. We hypothesize one novel vanadium complex of vanadium-enriched Cordyceps sinensis (VECS), which is beneficial in preventing depression in diabetes, and influences the long-term course of glycemic control. Vanadium compounds have the ability to imitate the action of insulin, and this mimicry may have further favorable effects on the level of treatment satisfaction and mood. C. sinensis has an antidepressant-like activity, and attenuates the diabetes-induced increase in blood glucose concentrations. We suggest that the VECS may be a potential strategy for contemporary treatment of depression and diabetes through the co-effect of C. sinensis and vanadium. The validity of the hypothesis can most simply be tested by examining blood glucose levels, and swimming and climbing behavior in streptozotocin-induced hyperglycemic rats.

    Abstract Abstract Growing evidence has shown that gut microbiome is a key factor involved in liver health. Therefore, gut microbiota modulation with probiotic bacteria, such as Saccharomyces boulardii, constitutes a promising therapy for hepatosis. In this study, we aimed to investigate the protective effects of S. boulardii on D-Galactosamine-induced liver injury in mice. Liver function test and histopathological analysis both suggested that the liver injury can be effectively attenuated by S. boulardii administration. In the meantime, S. boulardii induced dramatic changes in the gut microbial composition. At the phylum level, we found that S. boulardii significantly increased in the relative abundance of Bacteroidetes, and decreased the relative abundance of Firmicutes and Proteobacteria, which may explain the hepatic protective effects of S. boulardii. Taken together, our results demonstrated that S. boulardii administration could change the gut microbiota in mice and alleviate acute liver failure, indicating a potential protective and therapeutic role of S. boulardii.
