r active compound of DQP, G-Rb3 could ameliorate ROS-induced energetic metabolism dysfunction, maintain mitochondrial function and facilitate energy metabolism via directly targeting on RXRα. This study provides a promising strategy to dissect the effective patterns for TCM and finally promote the modernization of TCM. V.INTRODUCTION The association of higher hospital volume(HV) with lower mortality after open abdominal aortic aneurysm repair(OAAA) is well known; however, the underlying mechanism for improved outcomes is poorly understood. Better patient selection, lower risk of complications, and improved ability to rescue patients after adverse events are assumed mechanisms, but little data exist to validate this hypothesis. The purpose of this analysis was to determine the association of HV with patient selection, incidence of complications and failure to rescue(FTR) after adverse events resulting from OAAA repair. METHODS The Vizient database(>95% of all academic hospitals) was reviewed for OAAA repairs(elective, n=2827;non-elective, n=1622) performed from 2012-2014. Presentation type (elective vs. non-elective) was considered in all analyses. Elixhauser comorbidity index(EI) and Walraven-weighted scores(EWS) were assigned to patients and volume-outcome relationships explored. Using logistic regression, risk-adjusted compnalization of OAAA care. PURPOSE Aimed to characterize the CT imaging and clinical course of asymptomatic cases with COVID-19 pneumonia. METHODS Asymptomatic cases with COVID-19 pneumonia confirmed by SARS-COV-2 nucleic acid testing in Renmin Hospital of Wuhan University were retrospectively enrolled. The characteristics of CT imaging and clinical feature were collected and analyzed. RESULTS 58 asymptomatic cases with COVID-19 pneumonia admitted to our hospital between Jan 1, 2020 and Feb 23, 2020 were enrolled. All patients had history of exposure to SARS-CoV-2. On admission, patients had no symptoms and laboratory findings were normal. The predominant feature of CT findings in this cohort was ground glass opacity (GGO) (55, 94.8%) with peripheral (44, 75.9%) distribution, unilateral location (34, 58.6%) and mostly involving one or two lobes (38, 65.5%), often accompanied by characteristic signs. After short-term follow-up, 16 patients (27.6%) presented symptoms with lower lymphocyte count and higher CRP, mainly including fever, cough and fatigue. The evolution of lesions on CT imaging were observed in 10 patients (17.2%). The average days of hospitalization was19.80±10.82 days, and was significantly longer in progression patients (28.60±7.55 day). CONCLUSION CT imaging of asymptomatic cases with COVID-19 pneumonia has definite characteristics. Since asymptomatic infections as "covert transmitter", and some patients can progress rapidly in the short term. It is essential to pay attention to the surveillance of asymptomatic patients with COVID-19. CT scan has great value in screening and detecting patients with COVID-19 pneumonia, especially in the highly suspicious, asymptomatic cases with negative nucleic acid testing. BACKGROUND 2019 novel coronavirus disease (COVID-19) has become a worldwide pandemic. Under such circumstance pregnant women are also affected significantly. OBJECTIVE This study aims to observe the clinical features and outcomes of pregnant women who have been confirmed with COVID-19. METHODS The research objects were 55 cases of suspected COVID-19 pregnant women who gave a birth from Jan 20th 2020 to Mar 5th 2020 in our hospital-a big birth center delivering about 30,000 babies in the last 3 years. These cases were subjected to pulmonary CT scan and routine blood test, manifested symptoms of fever, cough, chest tightness or gastrointestinal symptoms. They were admitted to an isolated suite, with clinical features and newborn babies being carefully observed. Among the 55 cases, 13 patients were assigned into the confirmed COVID-19 group for being tested positive sever acute respiratory syndrome coronavirus 2(SARS-CoV-2) via maternal throat swab test, and the other 42 patients were assigned into the control gies (from confirmed mother and from normal mother) were subjected to SARS-CoV-2 examination by throat swab samples in 24 h after birth and no case was tested positive. CONCLUSION The clinical symptoms and laboratory indicators are not obvious for asymptomatic and mild COVID-19 pregnant women. Pulmonary CT scan plus blood routine examination are more suitable for finding pregnancy women with asymptomatic or mild COVID-19 infection, and can be used screening COVID-19 pregnant women in the outbreak area of COVID-19 infection. To achieve the kinetic resolution and enantioconvergent hydrolysis of rac-1,2-epoxyhexane, the E value of PvEH2 was enhanced by substituting its partial cap-loop. Based on the experimental results reported previously and computer-aided analysis, the flexible and variable cap-loop, especially its middle segment, was speculated to be related to the catalytic properties of PvEH2. In view of this, four PvEH2's hybrids, Pv2St, Pv2Pv1, Pv2Vr1 and Pv2Vr2, were designed by substituting the middle segment (190EGMGSNLNTSMP201) of a cap-loop in PvEH2 with the corresponding ones in StEH, PvEH1, VrEH1 and VrEH2, respectively. Then, the hybrid-encoding genes, pv2st, pv2pv1, pv2vr1 and pv2vr2, were constructed by fusion PCR, and expressed in E. coli Rosetta(DE3). The expressed hybrid, Pv2St, displayed the highest specific activity of 35.3 U/mg protein towards rac-1,2-epoxyhexane. The corresponding transformant, E. coli/pv2st, exhibited the largest E value of 24.2, which was 11.5-fold that of E. coli/pveh2 expressing PvEH2. The scale-up kinetic resolution of 280 mM rac-1,2-epoxyhexane was carried out using 40 mg dry cells/mL of E. coli/pv2st at 25 °C for 4.5 h, retaining (S)-1,2-epoxyhexane with >99.5% ees and 36.9% yield. Additionally, the chemo-enzymatic enantioconvergent hydrolysis of rac-1,2-epoxyhexane using E. coli/pv2st followed by sulfuric acid produced (R)-hexane-1,2-diol with 73.0% eep and 86.5% yield. V.Polysaccharides are essential macromolecules that are present in all living organisms. Vismodegib molecular weight They have a range of biological activities, such as antiviral, antioxidant, immunity-enhancing, and anticancer activities. In this study, a polysaccharide (PCPS) was separated and extracted from dry mycelium of Penicillium chrysogenum by a boiling water step and gel-filtration chromatography. Its structure was characterized by high performance gel-permeation chromatography, chemical derivative, and nuclear magnetic resonance analyses. The results showed that PCPS is a neutral galactomannan with an apparent molecular weight of 19.5 kDa. We evaluated the antiviral activity of PCPS. In half-leaf assays of tobacco plants, the protective effect of PCPS against Tobacco mosaic virus (TMV) was stronger than the protective effects of ningnanmycin and oligosaccharins. Electron microscopy analyses showed that PCPS can directly inactivate viral particles. The mechanism of the antiviral activity of PCPS was explored in a preliminary study.
