    Abstract Qing-Chang-Hua-Shi (QCHS) is a Chinese herbal formula, which is composed of 11 herbs. Studies have also shown that QCHS granules can alleviate colitis in animal models by preventing inflammatory responses and suppressing apoptosis through the MEK/ERK signaling pathway. To determine the efficacy and safety of QCHS granules in patients with moderately active UC. We performed a multicenter, randomized, placebo-controlled, double-blind study of patients with moderately active UC who did not respond to 4 weeks of mesalazine therapy at the maximum dose. Patients were randomly assigned to groups and administered QCHS granules (125 g/day, n = 59) or an identical placebo, which was similar to the QCHS granules in color and taste (125 g/day, n = 60), with continued 5-ASA 4 g/d therapy for 12 weeks. The primary outcome was the rate of clinical response and clinical remission at week 12. The secondary outcomes were health-related quality of life, endoscopic response rate, and mucosal healing rate. Any changes in mucus/bloody stool and diarrhea were recorded. Out of the 119 enrolled patients at 10 different centers in China, 102 patients completed the trial. Clinical remission and clinical response were seen in 31.48% and 92.59% of QCHS-treated patients, and 12.50% and 72.92% of placebo-treated patients, respectively. There was a significant difference between the two treatment groups. More patients receiving QCHS granules vs. placebo achieved remission of mucus/bloody stool (70.37% vs. 47.92%, P = 0.0361). Adverse event rates were similar (QCHS granules 38.33%; placebo 25.42%). In conclusion, QCHS granules were superior to the placebo in introducing clinical remission and mucosal healing, as well as in relieving mucus/blood stool in patients with moderately active and 5-ASA-refractory UC.

    Abstract The Lunar Penetrating Radar (LPR) onboard the Yutu-2 rover from China’s Chang’E-4 (CE-4) mission is used to probe the subsurface structure and the near-surface stratigraphic structure of the lunar regolith on the farside of the Moon. Structural analysis of regolith could provide abundant information on the formation and evolution of the Moon, in which the rock location and property analysis are the key procedures during the interpretation of LPR data. The subsurface velocity of electromagnetic waves is a vital parameter for stratigraphic division, rock location estimates, and calculating the rock properties in the interpretation of LPR data. In this paper, we propose a procedure that combines the regolith rock extraction technique based on local correlation between the two sets of LPR high-frequency channel data and the common offset semblance analysis to determine the velocity from LPR diffraction hyperbola. We consider the heterogeneity of the regolith and derive the relative permittivity distribution based on the rock extraction and semblance analysis. The numerical simulation results show that the procedure is able to obtain the high-precision position and properties of the rock. Furthermore, we apply this procedure to CE-4 LPR data and obtain preferable estimations of the rock locations and the properties of the lunar subsurface regolith.

    A Combined Study of In-Situ and Laboratory Spectral Measurements

    Abstract Until 29 May 2020, the Visible and Near-Infrared Imaging Spectrometer (VNIS) onboard the Yutu-2 Rover of the Chang’e-4 (CE-4) has acquired 96 high-resolution surface in-situ imaging spectra. These spectra were acquired under different illumination conditions, thus photometric normalization should be conducted to correct the introduced albedo differences before deriving the quantitative mineralogy for accurate geologic interpretations. In this study, a Lommel–Seeliger (LS) model and Hapke radiative transfer (Hapke) model were used and empirical phase functions of the LS model were derived. The values of these derived phase functions exhibit declining trends with the increase in phase angles and the opposition effect and phase reddening effect were observed. Then, we discovered from in-situ and laboratory measurements that the shadows caused by surface roughness have significant impacts on reflectance spectra and proper corrections were introduced. The validations of different phase functions showed that the maximum discrepancy at 1500 nm of spectra corrected by the LS model was less (~3.7%) than that by the Hapke model (~7.4%). This is the first time that empirical phase functions have been derived for a wavelength from 450 to 2395 nm using in-situ visible and near-infrared spectral datasets. Generally, photometrically normalized spectra exhibit smaller spectral slopes, lower FeO contents and larger optical maturity parameter (OMAT) than spectra without correction. In addition, the band centers of the 1 and 2 μm absorption features of spectra after photometric normalization exhibit a more concentrated distribution, indicating the compositional homogeneity of soils at the CE-4 landing site.

    Abstract Caveolin-1 (Cav-1), as an important structural protein of caveolae, has been proven to be correlated with several signal transduction pathways. Recent studies have shown that Cav-1 may play a critical role in response to DNA damage in irradiated pancreatic cancer cells. However, it is not known whether down-regulation of Cav-1 is required to enhance the damage of other kinds of human cells exposed to X-radiation. In this study, the role of Cav-1 in Chang liver cell line (CHL) exposed to X-radiation was investigated. Cav-1 knockdown cell line (CHL-CAV7) was stably established by the siRNA plasmids transfection, and Cav-1 expression was suppressed by 60%, compared with that of control group (CHL-C) which was transfected with non-targeting plasmids. Cellular survival ability and the expressions of proteins related to DNA damage and repair were examined by colony formation assay and Western blot, respectively. Down-regulation of Cav-1 expression induced a significant decrease of the survival rate in CHL-CAV7 cells exposed to 8 and 10 Gy X-radiation. Compared with CHL-C cells, CHL-CAV7 cells showed increased γH2AX expression, as well as decreased p-ATM, DNA-dependent protein kinase, catalytic subunit (DNA-PKcs) and p53 protein expressions when treated with X-radiation. Meanwhile, the colocalization of Mdm2 and Cav-1 was decreased in CHL-CAV7 cells compared with that in CHL-C cells. These results suggest that the down-regulation of Cav-1 may aggravate DNA damage of CHL cells through reducing the interaction of Cav-1 and Mdm2, which results in the promotion of p53 degradation.

    Abstract The Zhang 22 well was drilled in the Ordos Basin, penetrating the Chang 7 Member of the Triassic Yanchang Formation, which, cumulatively, has more than 80 m (>260 ft) of black organic-rich shale of oil window maturity. Using 76 samples collected every 1 m (3 ft) from the well, the effects of stratigraphic fractionation and petroleum expulsion within five intervals of the Chang 7 shale were qualitatively and quantitatively documented. The organic-rich intervals 1, 2, and 5, having an average total organic carbon (TOC) of 6.79 wt. % and pyrolyzable hydrocarbon potential of 9.40 mg/g rock (i.e., the amount of hydrocarbons generated by pyrolysis between 300°C and 650°C [S2]), are defined as “generative units” in the Chang 7 shale system, compared to the “in-source reservoirs” or “sweet spots” (i.e., the third and fourth intervals), which contain a lower average TOC of 4.19 wt. % and an average S2 value of 7.17 mg/g rock, but the highest amount of free oil (average total oil of 7.35 mg/g rock). Geochemical and molecular compositions display distinctive differences between samples from these source and reservoir groupings. For example, bitumens from the generative units proportionally possess lower saturated hydrocarbons (56%–66%) than those from the in-source reservoirs (up to 81%). The proportions of aromatic and polar compounds in the generative units are accordingly higher than in their counterpart. The individual molecular weight distribution of sample extracts displays more light-end moieties being enriched in the generative units. By applying the compositional mass balance calculation, the overall and compound-specific expulsion efficiencies in the in-source reservoirs are abnormally negative compared to the positive values in the generative intervals. This finding, in conjunction with the effects of the preferential retention of aliphatic hydrocarbons and the differential expulsion of light molecular weight compounds in the in-source reservoirs, indicates a short-distance intrasource migration of generated petroleum into the sweet-spot intervals (intervals 3 and 4) from the overlying units (intervals 1 and 2) and the underlying interval 5. Furthermore, when quantifying the total amount of retained petroleum in the shale system, an amended assessment has been introduced to overcome the systematic misestimations if only unextracted values for the amount of thermally extractable hydrocarbons volatilized at 300°C (mg HC/g rock) were considered. Thus, the oil crossover effect, temperature at which the rate of S2 generation is at maximum shift phenomenon, and the hydrogen index being shifted to higher values after extraction all account for identifying intervals 3 and 4 as the in-source reservoirs. In this study, we have not only identified a set of promising in-source targets for shale oil exploration and production, but we also presented the chemical and molecular composition for these shale oils. We have additionally speculated for the intrasource migration model and further discussed the different expulsion efficiencies in the shale system upon the compositional mass balance calculation as well as the stratigraphic fractionation on differentiating the chemical compositions during migration. The improved oil quality by fractionation, the extra storage potential derived from microfossil quartz, the weak adsorptive affinity of oil to organic matter, and the good shale susceptibility to hydraulic fracturing all give a promising prospective for exploring and producing shale oil from the Chang 7 shale system in the Ordos Basin.

    Abstract Length–weight relationships were determined for two loach species, Sinibotia superciliaris (Günther, 1892) and Sinibotia reevesae (Chang, 1944). Samples were collected with gill nets (30 × 15 m, mesh‐size 1.5 cm) and fish cages (mesh‐size 0.5 cm) as well as by electroshock (CWB‐2000 P, 12 V, 250 HZ) between May 2013 and June 2015 from the Tuojiang River in southwest China. It is believed that the size range covered is close to a commonly known size range of each species. The length–weight relationship values of b were determined as 3.105 for S. superciliaris and 3.381 for S. reevesae. The data will be helpful in further research regarding these species in the upper Yangtze River Basin.
