Patients with Coronavirus Disease 2019 (COVID-19), due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection mainly present with respiratory issues and related symptoms, in addition to significantly affected digestive system, especially the intestinal tract. While several studies have shown changes in the intestinal flora of patients with COVID-19, not much information is available on the gut virome of such patients. In this study, we used the viromescan software on the latest gut virome database to analyze the intestinal DNA virome composition of 15 patients with COVID-19 and investigated the characteristic alternations, particularly of the intestinal DNA virome to further explore the influence of COVID-19 on the human gut.

Patients were categorized according to the phase of CHB, as follows: immune tolerance (ITP); immune clearance (ICP); low or nonreplication (LRP); reactivation (RAP); hepatic cirrhosis (HC); and primary liver cancer (PLC). TCMS patterns were classified among the following types: spleen-kidney deficiency (SKD); liver-qi depression (LQD); damp-heat in liver-gallbladder (LGDH); liver-kidney deficiency (LKD); and blood stasis blocking collateral (BSBC).

Methods: A randomized double-blinded trial was performed. Eligible female patients with RUTI were recruited from one hospital and two community health centers.
Objectives: To investigate the resistance and virulence profiles of uropathogenic Escherichia coli (UPEC) and its treatment by Chinese medicine (CM) Fuzheng Qingre Lishi Formula (, FQLF).
Methods: UPEC strains were isolated from recurrent urinary tract infections (UTIs) patients. Patient sensitivities to 17 antibiotics were tested by the disk diffusion method.
The aim of the present study was to investigate the antidepressant-like effects of two fractions, including petroleum ether soluble fraction (Fraction A, FA) and water-EtOH soluble fraction (Fraction B, FB) prepared from the Danzhi-xiaoyao-san (DZXYS) by using chronic unpredictable mild stress-induced depressive rat model. The results indicated that DZXYS could ameliorate the depression-like behavior in chronic stress model of rats. The inhibition of hyperactivity of HPA axis and the modulation of monoamine and amino acid neurotransmitters in the hippocampus may be the important mechanisms underlying the action of DZXYS antidepressant-like effect in chronically stressed rats.

We investigated whether providing patients with an Internet web-site link recommended by their physician would improve patient knowledge and satisfaction. Our hypothesis was that directing patients to a reliable web site would improve both.

Here, we demonstrate that T helper cell type 2 cytokines and, in particular, IL-4 condition human and murine monocyte phenotype toward Arg-1(+), and their subsequent behavior limits angiogenesis by increasing soluble fms-like tyrosine kinase 1 (sFlt-1) gene expression. We document that T helper cell type 2 cytokine-conditioned murine macrophages neutralize vascular endothelial growth factor-mediated endothelial cell proliferation (human umbilical vein endothelial cell and choroidal vasculature) in a sFlt-1-dependent manner.

Methods: The acute hepatic injury model was established by LPS/D-GalN and then intervened with Qingxia therapy. Serum liver function, PT and liver tissue pathology were observed, hepatocyte apoptosis index was detected by Tunel, protein expressions of BCL-2, BAX and Caspase-3 were detected by Western blotting.

We aimed to investigate the preventive effects of acupuncture for complications after radical hysterectomy. A single-center randomized controlled single-blinded trial was performed in a western-style hospital in China. One hundred and twenty patients after radical hysterectomy were randomly allocated to two groups and started acupuncture from sixth postoperative day for five consecutive days.

Whether inhibitory CD200R signaling regulates pro-angiogenic macrophage phenotypes with the potential to suppress ocular neovascularization is unknown. CD200R-deficient bone marrow derived macrophages (BMMΦ) were used to demonstrate that macrophages lacking this inhibitory receptor exhibit enhanced levels of Vegfa, Arg-1 and Il-1β when stimulated with PGE2 or RPE-conditioned (PGE2-enriched) media.

One possibility that is a pre-eminent drive is a specific and early conditioning and activation of the myeloid cell infiltrate. Using a laser-induced CNV murine model, we have identified that disruption of retinal pigment epithelium (RPE) and Bruch's membrane resulted in an early recruitment of macrophages derived from monocytes and microglia, prior to angiogenesis and contemporaneous with lesional complement activation.

Previously, we demonstrated that Sini decoction prevented doxorubicin-induced heart failure in vivo. However, its active components are still unclear.

Polysaccharides from Fuzi (FPS) reportedly have protective effects on nutrition-limited livers. The present study was designed to determine whether FPS protected H9c2 cells against starvation-induced cytotoxicity using an AMPK/mTOR-dependent mechanism.

Chinese medicines that remove blood stasis not only promote blood circulation but also calm the endopathic wind, remove heat, resolve phlegm, remove toxic substances and strengthen body resistance. The medicinal targeting effect of Chinese medicine can promote the homing of BMSCs, and the synergistic therapeutic effects of drugs can contribute to BMSC differentiation.

This study investigated the effects of homocysteine (Hcy) on angiogenesis in cultured human umbilical vein endothelial cells (HUVEC) and zebrafish embryos. We found that Hcy (50 micromol/L) significantly decreased cell numbers, viability, and induced a G1/S arrest in HUVEC in the presence of adenosine (Ade, 50 micromol/L). Hcy, in combination with Ade, reduced migration and suppressed tube-like formation on Matrigel in HUVEC.

Chinese integrative medicine (CIM) focuses on the integration of conventional medicine (biomedicine) with Chinese medicine (CM). Although the CIM field has witnessed several advancements, the definition and classification of CIM is not quite clear, given that an independent theory system has not yet been established in this field. Therefore, future research and studies should focus on the following objectives: (1) emphasizing CM features, (2) improving CIM positioning, and (3) establishing CIM standards.

This study investigated the effects of Rb1, a major ginsenoside in ginseng, on H2O2-induced senescence in primary human umbilical vein endothelial cells (HUVECs).
Methods And Results: Real-time PCR and Western blot were used to detect the mRNA and protein expression, respectively.
Senescence of endothelial cells has been proposed to play an important role in endothelial dysfunction and atherogenesis. In the present study we aimed to investigate whether ginsenoside Rb1, a major constituent of ginseng, protects endothelial cells from H(2)O(2)-induced endothelial senescence. While H(2)O(2) induced premature senescent-like phenotype of human umbilical vein endothelial cells (HUVECs), as judged by increased senescence-associated β-galactosidase (SA-β-gal) activity, enlarged, flattened cell morphology and sustained growth arrest, our results demonstrated that Rb1 protected endothelial cells from oxidative stress induced senescence.
