Objective: To investigate the effects of psycholog ical factors on treatment and outcome of patients with high altitude pulmonary e dema(HAPE). Methods: In the present study, one hundred and fifty -two patients with HAPE were tested by hospital anxiety and depression scale. Results: The results showed that there were 61 patients (40.13%) with anxiety and 29 patients (19.08%) with depression. The important factors on mental state of patients were preventive education, the first time suffering HA PE, characters of patients, degree of the disease and the medical fee, the less w ere age, sex, occupation and education of patients. Duration of rales of lung an d course of illness were significantly prolonged in HAPE patients with mental di sorders compared to the patients without mental disorder. Conclusion:The study suggests that anxiety and depression might aggravate the state of HAPE.

This study aims to explore the molecular mechanism of Ganoderma against gastric cancer based on network pharmacology, molecular docking, and cell experiment. The active components and targets of Ganoderma were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and gastric cancer-related targets from GeneCards and Online Mendelian Inheritance in Man(OMIM). The protein-protein interaction(PPI) network of the common targets was constructed with STRING, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis of the common genes based on Bioconductor and R language. The medicinal-disease-component-target network and medicinal-disease-component-target-pathway network were established by Cytoscape. Molecular docking was performed between β-sitosterol(the key component in Ganoderma) and the top 15 targets in the PPI network. Cell experiment was performed to verify the findings. A total of 14 active components and 28 targets of Ganoderma were retrieved, and the medicinal and the disease shared 25 targets, including caspase-3(CASP3), caspase-8(CASP8), caspase-9(CASP9), and B-cell lymphoma-2(BCL2). The common targets involved 72 signaling pathways and apoptosis and p53 signaling pathway may play a crucial role in the effect of Ganoderma against gastric cancer. β-sitosterol had strong binding activity to the top 15 targets in the PPI network. The in vitro cell experiment demonstrated that β-sitosterol inhibited gastric cancer AGS cell proliferation by inducing cell apoptosis and cell cycle arrest in the S phase, which might be related to the regulation of the p53 pathway. This study shows the multi-component, multi-target, and multi-pathway characteristics of Ganoderma against gastric cancer, which lays a scientific basis for further research on the molecular mechanism.

OBJECTIVETo compare the modulatory effects of human amniotic epithelial cells (H-AECs), human amniotic mesenchymal cell (HA-MSCs), umbilical mesenchymal cells (UC-MSCs) on the inflammatory status of lipopolysaccharide (LPS)-induced RAW264.7 cells.

METHODSRAW264.7 cells stimulated with LPS were co-cultured with H-AECs, HA-MSCs, or UC-MSCs or cultured in conditioned media of the 3 stem cells to assess the changes of the inflammatory status of RAW264.7 cells. The migration ability, nitric oxide concentration, and expressions of the pro-inflammatory and anti-inflammatory genes, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNFα), and inducible nitric oxide synthase (NOS-2) of M1 macrophages, and Arg-1, CD206, and CD36 of M2 macrophages, were detected in the co-cultures.

RESULTSCompared with the control macrophages, RAW264.7 cells cultured in the conditioned media of H-AECs, HA-MSCs, and UC-MSCs all showed significantly lowered migration abilities (P<0.05). Co-culture with H-AECs, but not the other two stem cells, resulted in a significant reduction of NO production (P<0.05) and significant down-regulation of IL-1β, TNFα, NOS-2, and INFβ expressions in RAW264.7 cells; co-culture with HA-MSCs and UC-MSCs only caused a down-regulation of INFβ mRNA expression. In all the 3 RAW264.7 and stem cell co-cultures, the expressions of the inflammation related genes including Arg-1, CD206, and CD36 were up-regulated significantly.

CONCLUSIONH-AECs, HA-MSCs, and UC-MSCs can all prevent RAW264.7 cells from differentiating into M2 macrophages, but their effects and mechanisms are different from one another.

Human bocavirus, which was firstly discovered in 2005, is a new human parvovirus associated with lower respiratory tract infection in children. In this study, a human bocavirus, named WLL-1 isolate, was identified in Wenlin County, Zhejiang Province. The genome of bocavirus WLL-1 has been sequenced and analyzed. Phylogenetic analyses showed that WLL-1 shares 99% homology with other bocaviruses recently reported, but also has some special variations.
