    Abstract: Patients with severe acute pancreatitis (SAP) have gastrointestinal dysfunction, and enteral nutrition intolerance is easy to occur during the implementation of enteral nutrition, which leads to the suspension or termination of enteral nutrition. Enteral nutrition cannot tolerate the influence of many factors. At present, there is a lack of analysis on the influencing factors of enteral nutrition intolerance in patients with SAP. Therefore, this study analyzed the factors of enteral nutrition intolerance in patients with SAP by meta-analysis, to provide a basis for the protection of enteral nutrition in patients with SAP. Methods: Databases (PubMed, Embase, Cochrane Library, Web of Science, China Biology Medicine Database, China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang) were searched using index words to find relevant studies published before March 2021. Meta-analyses of relative risk were performed for the identification of risk factors. Results: We will disseminate the findings of this systematic review and meta-analysis via publications in peer-reviewed journals. Conclusion: This study systematically reviewed the existing evidence and determined the incidence and predictors of enteral nutrition intolerance in patients with SAP.

    Abstract: Rice false smut (RFS) caused by Ustilaginoidea virens has been one of the most severe rice diseases. Fungicide-based chemical control is a significant measure to control RFS. In the sensitivity determination of quinone outside inhibitor (QoI) fungicide in vitro, salicylhydroxamic acid (SHAM) has been commonly added to artificial culture media in order to inhibit alternative oxidase of phytopathogenic fungi. However, some studies showed that artificial media should not include SHAM due to its toxicity. Whether SHAM should be added in the assay of U. virens sensitivity to QoI fungicide remains unknown. In this study, two appropriate media, potato sucrose agar (PSA) and minimal medium (MM), were selected to test SHAM toxicity and sensitivity of U. virens to azoxystrobin and pyraclostrobin. The mycelial growth and sensitivity to azoxystrobin and pyraclostrobin had no significant difference between on PSA and MM. SHAM could significantly inhibit mycelial growth, conidial germination, peroxidase (POD) and esterase activity of U. virens. Average effective concentration for inhibiting 50% (EC50) values of SHAM against mycelial growth of ten U. virens were 27.41 and 12.75 μg/mL on PSA and MM, respectively. The EC50 values of SHAM against conidial germination of isolates HWD and JS60 were 70.36 and 44.69 μg/mL, respectively. SHAM at 30 μg/mL significantly inhibited POD and esterase activity of isolates HWD and JS60, and even SHAM at 10 μg/mL significantly inhibited POD activity of isolate HWD. In addition, SHAM significantly reduced EC50 values and EC90 values of azoxystrobin and pyraclostrobin on both PSA and MM. Even in the presence of SHAM at 10 μg/mL, average EC50 values of ten U. virens isolates for azoxystrobin decreased 1.7-fold on PSA and 4.8-fold on MM, and for pyraclostrobin that decreased 2.8-fold on PSA and 4.8-fold on MM. Therefore, these results suggest that SHAM should not be included in artificial media in the assay of U. virens sensitivity to QoI fungicides.

    Abstract: Rice false smut (RFS), caused by Ustilaginoidea virens, is an important fungal disease of rice. In China, Methyl Benzimidazole Carbamates (MBCs), including carbendazim, are common fungicides used to control RFS and other rice diseases. In this study, resistance of U. virens to carbendazim was monitored for three consecutive years during 2018 to 2020. A total of 321 U. virens isolates collected from Jiangsu Province of China were tested for their sensitivity to carbendazim on PSA. The concentration at which mycelial growth is inhibited by 50% (EC50) of the carbendazim-sensitive isolates was 0.11 to 1.38 µg/mL, with a mean EC50 value of 0.66 μg/mL. High level of resistance to carbendazim was detected in 14 out of 321 isolates. The resistance was stable but associated with a fitness penalty. There was a statistically significant and moderate negative correlation (r= −0.74, p 〈 0.001) in sensitivity between carbendazim and diethofencarb. Analysis of the U. virens genome revealed two potential MBC targets, Uvβ1Tub and Uvβ2Tub, that putatively encode β-tubulin gene. The two β-tubulin genes in U. virens share 78% amino acid sequence identity, but their function in MBC sensitivity has been unclear. Both genes were identified and sequenced from U. virens sensitive and resistant isolates. It is known that mutations in the β2-tubulin gene have been shown to confer resistance to carbendazim in other fungi. However, no mutation was found in the Uvβ2Tub gene in either resistant or sensitive isolates. Variations including point mutations, non-sense mutations, codon mutations, and frameshift mutations were found in the Uvβ1Tub gene from the 14 carbendazim-resistant isolates, which have not been reported in other fungi before. Thus, these results indicated that variations of Uvβ1Tub result in the resistance to carbendazim in field isolates of Ustilaginoidea virens.

    Abstract: The absorption, distribution, and transport trends of organic and inorganic arsenic (As) in honesuckle ( Lonicera japonica ) were studied using synchrotron X-ray fluorescence spectroscopy (μ-XRF). The root, stem, and leaf samples were analyzed by μ-XRF, proving that in the presence of dimethyl arsenate acid, a small amount of As accumulated in local areas of the epidermis and cortex of roots, while most of As migrated to the upper plant through the middle vascular column. After reaching the stem, As was mainly distributed in the outer skin, indicating that the root and stem of L. japonica blocked the transport of As in the plant. In the presence of As( iii ), A large amount of As accumulated in the epidermis and cortex of the root, reducing its further transport from the plant roots. Once As entered the stem of L. japonica from the root, it achieved a strong transport capacity, thus causing severe harm to plants. The element correlation analysis revealed that As in L. japonica had the strongest correlation with Cu and Zn elements, for the future research on the influence of As pollution on plants, the interference based on the above two elements can be considered.

    Abstract: Substitution of lead (Pb) with environmentally friendly germanium (Ge) is a very important and promising method to reduce the toxicity and improve the efficiency and stability of perovskite films for practical applications in light-emitting diodes (LEDs) and solar cells. However, a previous study shows that the efficiency of LEDs based on the germanium–lead (Ge–Pb) perovskites will decrease as the Ge content exceeds 30%, due to trap-assisted recombination. Here we demonstrate highly luminescent sky-blue Ge 0.3 Pb 0.7 -based perovskite films with photoluminescence quantum efficiencies (PLQEs) of up to 48%, showing a relative improvement of 17% over similarly prepared Ge-free, Pb-based ones. The PL stability of the Ge 0.3 Pb 0.7 -based perovskite films is also relatively improved compared to that of the Pb-based ones. The reasons of the PL efficiency and stability improvement are discussed in this study. The symmetry-adapted shear strain variations related to the suppression of the Jahn–Teller distortion after Ge substituting could play an important role in increasing the stability of the Ge-inclusion perovskites.

    Abstract: 2D van der Waals (vdWs) heterostructure‐based multifunctional field effect transistor (FET) has brought about novel physical phenomena. Impressively, anti‐ambipolar characteristic is one of the basis logic functions being used in multi‐valued inverters, which is analogous to negative differential resistance (NDR)‐based transistor. Here, the tunable current‐transport and self‐driven optoelectrical properties of vertically stacked multilayer GeSe/SnS 2 heterostructure are reported. In particular, it allows to be switched from n‐type‐dominant behavior to anti‐ambipolar operation regime (a large peak‐to‐valley ratio (PVR) of 1.5 × 10 3 ) as a result of different band‐bending under various bias. Under light‐doping engineering, the inverted V‐shaped peak is distinctly shifted because of the higher carrier recombination probability of p‐GeSe component. Besides, for photovoltaic performances, the device exhibits an ultralow dark current of ≈30 fA, a maximum responsivity of 130 mA W −1 , and high I on / I off ratio of ≈10 5 under 532 nm because of the large band offset and the efficient carrier separation process. Meanwhile, the polarization sensitivities can reach 1.9 at 405 nm and 2.6 at 635 nm. It is found that the polarity‐switchable behavior and self‐driven photodetection performance in GeSe/SnS 2 vdWs FET can hopefully broaden and simplify the multifunctional integrated devices in the future.

    Abstract: Hybrids composed of two-dimensional (2D) and zero-dimensional (0D) materials have demonstrated great application potentials in electronics and optoelectronics. The CdSe@Zn1−XCdXS (CSZCS) quantum dots (QDs) possess unique gradient band structure with a continuously increasing energy level along the radial direction from the center to the surface, which is favorable for light-harvesting, photocarrier transfer and promising for photovoltaic and photodetection applications. Here, the gradient alloyed CSZCS QDs, acting as a photosensitive layer, have been first integrated with 2D InSe as a carrier transport layer. The new 2D–0D hybrids exhibit a 300-fold improvement in responsivity compared with that of pristine InSe, which is much more superior to hybrids composed of core–shell CdSe@ZnS QDs/InSe. Thanks to the low dark current and large photo-gain induced by the photo-gating effect, the responsivity and detectivity of the CSZCS QDs/InSe photodetector can reach up to 30.16 A/W and 1.69 × 1012 Jones, respectively. This work provides a new kind of promising QDs with the gradient alloyed structure that can be explored into 2D–0D hybrids for further development of high-performance photodetectors.
