Yinchenzhufu decoction (YCZFD) is a classic formula for treating Yin Huang syndrome, which can improve liver injury caused by cholestasis. However, the mechanism of action of YCZFD still remains unclear. This article used network pharmacology, molecular docking, animal experiments, and molecular biology methods to explore the mechanism of YCZFD in treating liver injury caused by cholestasis. A mouse model of acute cholestasis induced by lithocholic acid was used to investigate the effects of YCZFD on liver injury. The experimental procedures described in this paper were reviewed and approved by the Ethical Committee at the Shanghai University of Traditional Chinese Medicine (approval NO. PZSHUTCM190823002). The results showed that YCZFD could reduce the levels of blood biochemical indicators and improve hepatocyte damage of cholestatic mice. Then, multiple databases were used to predict the corresponding targets of YCZFD active components on cholestatic liver injury. An intersection target protein-protein interaction (PPI) networks based on String database and Cytoscape software was used to demonstrate the possible core targets of YCZFD against cholestatic liver injury. The results indicated that core targets of YCZFD include tumor necrosis factor, interleukin-1

Objective To investigate the effect of bone mesenchymal stem cells on Toll-like receptors (TLR) 2/4 expression in the lungs of rats with acute hemorrhagic necrotizing pancreatitis (AHNP). Methods Seventy SD male rats were randomly divided into sham-operation group (n=10), AHNP group(n=30) and MSCs-treated group(n=30). Masc rate of BMSCs with surface mark were measured by flow cytometer. TLR2/4mRNA expression in the the lung were measured by RT-PCR, and The ratio of Wet/dry and lung histological changs were observed. Results TLR2/4 mRNA could be detected in the lungs with low values in sham-operation group, markedly increased in 3 h, and peaked in 12 h in AHNP group (P<0.05). Lung injuries were aggravated and the levels of TNF-α in the lung were increased (P<0. 05) . Treatment with MSCs could effectively inhibit TLR2/4 mRNA expression and relieve lung injuries. The levels of TNF-α in the lung were decreased (P<0.05). Conclusions The expression of TLR2/4 mRNA is increased in the lungs in AHNP and the lung injuries are aggravated. MSCs could markedly inhibit TLR2/4 mRNA expression in the lungs in AHNP, which would lead to relief of lung injury.

To establish vascular endothelial growth factor (VEGF) and interleukin-8 (IL-8) as secretary biomarkers for cell growth on topographic substrates, we have evaluated the secretion and expression of these 2 factors by SH-SY5Y human neuroblastoma cells on poly-L-lactide (PLLA) micropillar arrayed topographic substrates. We fabricated topographic substrates with UV lithography, silicon etching and polydimethylsiloxane-based replica molding, and interfaced SH-SY5Y human neuroblastoma cells with both the topographic substrates and PLLA flat substrates. Cell morphology and spreading were examined with scanning electron microscopy. The secretion and mRNA expression of VEGF and IL-8 were evaluated with enzyme linked immunosorbent assay (ELISA) and real time qPCR, respectively, 24 hours after cell plating. We successfully achieved 4 topographic substrates with a nominal pillar diameter of 2 microm and 4 microm, and a nominal pillar spacing of 2 microm and 7 microm. We found that the secretion and mRNA expression of VEGF and/or IL-8 by SH-SY5Y cells on 2-2 microm (pillar diameter-spacing), 4-2 microm and 4-7 microm topographic substrates were upregulated in comparison to those by cells on PLLA flat substrate, 24 hours after cell plating. Furthermore, both cytokines were even more substantially upregulated on the 2-7 microm substrate than on the other 3 topographic substrates. Compared to those on PLLA flat substrate, cells on topographic substrates showed significant changes in morphology (spreading area, perimeter and roundness), and the increase in the secretion and mRNA expression of VEGF and IL-8 was accompanied with a decrease in cell spreading areas. These results provided evidence that pillar arrayed topography was an important microenvironmental factor in affecting VEGF and IL-8 expression or secretion, and VEGF and IL-8 might serve as important secretary biomarkers for growth on topographic substrates by SH-SY5Y cells.

OBJECTIVETo explore the effect of negative emotions on serum levels of adrenocorticotropic hormone (ACTH) and neuropeptide Y (NYP) in hepatitis B liver cirrhosis (HBLC) patients.
METHODSTotally 617 HBLC patients were assigned to the negative emotion group (415 cases) and the non-negative emotion group (202 cases) judged by negative emotions. Case numbers of various grading Child-Pugh were recorded in the two groups. Their liver functions were compared between the two groups. Serum levels of ACTH and NPY were detected using double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in the two groups.
RESULTSThere was no statistical difference in Child-Pugh grading between the two groups (χ2 = 0.65, P = 0.72). Compared with the non-negative emotional group, serum ACTH levels decreased significantly in the negative emotion group with statistical difference (P < 0.05). There was no statistical difference in serum ACTH levels between the two groups (P > 0.05).
CONCLUSIONThe negative emotion of HBLC patients was not related to the serum ACTH level, but to relatively lower-concentration serum NPY levels.

Objective To measure the maximum movement of the hyoid bone and ventriculus laryngis during normal swallowing. Methods Forty volunteers were selected as subjects, and an X?ray simulator was used to collect the videos of normal swallowing. Video analysis software was used to capture continuous and quick screenshots of these videos, and the maximum movement of the hyoid bone and ventriculus laryngis was measured. The difference in movement was analyzed by one?way analysis of variance. Results The mean time for swallowing in 40 volunteers was 1.13±0.28 s. During the process of swallowing, the hyoid bone and ventriculus laryngis moved upward first, then outward, and finally returned to the resting position. The maximum movement of the hyoid bone forward and backward was 0.90±0.30 cm;the maximum vertical movement of the hyoid bone was 0.93±0.36 cm. The maximum movement of the ventriculus laryngis forward and backward was 0.69± 0. 25 cm;the maximum vertical movement of the ventriculus laryngis was 1.04±0.45 cm. Further studies showed the effect of age on the time for swallowing (P=0.03), with similar results for the male and female ( P=0.13) . Sex and age had no effects on movement of the hyoid bone and ventriculus laryngis (P=0.28?0.81 and 0.20?0.88). Conclusions During normal swallowing, the hyoid bone and the ventriculus laryngis move first upward and then forward. These movements should be considered during the development of radiotherapy plan for head and neck cancer.
