From ZINC database with a total of 1.8 million small molecules, four compounds are identified as prolyl hydroxylase 2 inhibitors through a virtual screening workflow that sequentially incorporates machine learning, molecular docking, and molecular dynamics. Among them, compound 103,(E)-5-(5-((2-(1Htetrazol-5-yl)hydrazineylidene)methyl)furan-2-yl)isoindoline-1,3-dione, promotes the migration and capillary tube formation capacity of human umbilical vein endothelial cells through enhancing the stability of hypoxia inducible factor-1α and increasing the level of vascular endothelial growth factor.

Scrub typhus is an acute febrile disease caused by Orientia tsutsugamushi （0. tsutsugamushi）. We report herein the case of a woman who presented with fever and elevated serum levels of liver enzymes and who was definitively diagnosed with scrub typhus by his- topathological examination of liver biopsy specimens, serological tests and nested polymerase chain reaction. Immunohistochemical staining using a monoclonal an- ti-O. tsutsugamushi antibody showed focally scattered positive immunoreactions in the cytoplasm of some hepatocytes. This case suggests that scrub typhus hepatitis causes mild focal inflammation due to direct liver damage without causing piecemeal necrosis or interface hepatitis. Thus, scrub typhus hepatitis differs from acute viral hepatitis secondary to liver damage due to host immune responses, which causes severe Iobular disarray with diffuse hepatocytic degeneration, necrosis and apoptosis as well as findings indicative of hepatic cholestasis, such as hepatic bile plugs or brown pigmentation of hepatocytes.

AIM： To compare the effects of the surgical insult of cataract surgery on corneal inflammatory infiltration, neovascularization （NV） and lymphangiogenesis （LY） between the dry eye and non-dry eye in murine cataract surgery models.METHODS： We established two groups of animals, one with normal eyes （non-dry eye） and the second with induced dry eyes. In both groups, we used surgical insults to mimic human cataract surgery, which consisted of lens extraction, corneal incision and suture. After harvesting of corneas on the 9th postoperative day and immunohistochemical staining, we compared NV, LY and CD11b＋ cell infiltration in the corneas.RESULTS： Dry eye group had significantly more inflammatory infiltration （21.75%±7.17% r/s 3.65%±1.49%; P=0.049）. The dry eye group showed significantly more NV （48.21% ±4.02% ys 26.24% ±6.01% ; P =0.016） and greater levels of LY （9.27%±0.48% ys 4.84%±1.15%; P= 0.007）. In corneas on which no surgery was performed, there was no induction of NV in both the dry and non- dry group, but dry eye group demonstrated more CD11b＋ cells infiltration than the non-dry eye group （0.360%± 0.160% vs 0.023%±0.006%; P=0.068）. Dry eye group showed more NV than non-dry eye group in both topical PBS application and subconjunctival PBS injection （P= 0.020 and 0.000, respectively）.

OBJECTIVE: To investigate the effects of Gyejibokryeong-Hwan(Guizhifuling-wan, GBH) on muscle injury in a mouse model of muscle ***: C57/BL6 mouse biceps femoris muscles were injured using the drop-mass method and injured animals were treated orally with GBH(50,100, or 500 mg/kg) once a day for 7 d. Open field and treadmill running tests were performed to assess functional recovery from muscle injury. The production of pro-inflammatory cytokines was examined by enzyme-linked immunosorbent assay and Western blotting analysis. Expression of the muscle regeneration biomarkers, myoblast determination(Myo D), myogenic factor 5(Myf5), and smooth muscle actin(α-SMA), in the biceps femoris muscle was investigated at the protein and m RNA level by Western blotting and real time-PCR, respectively. Histological analysis was performed using hematoxylin and eosin staining. Finally, myosin heavy chain production was investigated in differentiated C2C12 myoblasts in the presence of ***: GBH treatment markedly improved locomotion and running behavior. GBH significantly inhibited the secretion of monocyte chemoattractant protein-1 into the bloodstream in muscle-contused animals. The levels of Myo D, Myf5, and α-SMA protein and m RNA were significantly up-regulated by GBH in injured muscle tissue. Histological studies suggested that GBH facilitated recovery from muscle damage. However, GBH did not induce the production of myosin heavy chain in ***: Overall, the present study suggested that GBH improves the recovery of the injured muscles in the mouse model of muscle contusion.

Ni-based electrocatalysts with strong redox abilities are active for the electrochemical oxidation of 5-hydroxymethylfurfural(HMF). Interface engineering is an efficient way to modulate the electronic structure, tune the intermediate adsorption, and expose more active sites. Herein, we increased the concentration of interfacial sites with rich defects in a 3D hierarchical nanostructured NiO-Co3O4 electrocatalyst and investigated its catalytic performance for HMF electro-oxidation. The interface effect created abundant cation vacancies, modulated the electronic properties of Co and Ni atoms, and raised the oxidation state of Ni species. The NiO-Co3O4 catalysts show superb HMF oxidation activities with a low onset potential of 1.28 ***, in-situ surface-selective vibrational spectroscopy of sum-frequency generation was performed to study the reaction pathway during the oxidation process on the electrocatalysts. The current study offers an efficient way to create cation vacancies and proves the decisive role of cation vacancies in catalyzing the HMF electro-oxidation.
