摘要：
The urchin-like trimetallic nanozyme Pd-Pt-Ir was firstly prepared through atomic replication. Due to the high affinity to H2O2, the activity of Pd-Pt-Ir is higher than that of Pd-Pt. Based on this concept, Pd-Pt-Ir was applied for the detection of ascorbic acid and hydrogen peroxide. The linear range of ascorbic acid and hydrogen peroxide were 25-800 mu M and 3.9-62.5 mM, respectively, and the LODs were11.7 mu M and 3.6 mM, respectively. Furthermore, the Pd-Pt-Ir nanozyme was applied for the rapid detection of ascorbic acid, and a test strip was built. Ascorbic acid concentrations ranging from 0 to 31.2 mM were observed. Based on this work, the simple and rapid method proposed offers excellent application prospects for the detection of ascorbic acid and hydrogen peroxide.

摘要：
Hydrogen sulfide (H(2)S) is the third gaseous signaling molecule discovered in the body after NO and CO and plays an important organismal protective role in various diseases. Within adipose tissue, related catalytic enzymes (cystathionine-β-synthetase, cystathionine-γ-lyase, and 3-mercaptopyruvate transsulfuration enzyme) can produce and release endogenous H(2)S. Atherosclerosis (As) is a pathological change in arterial vessels that is closely related to abnormal glucose and lipid metabolism and a chronic inflammatory response. Previous studies have shown that H(2)S can act on the cardiovascular system, exerting effects such as improving disorders of glycolipid metabolism, alleviating insulin resistance, protecting the function of vascular endothelial cells, inhibiting vascular smooth muscle cell proliferation and migration, regulating vascular tone, inhibiting the inflammatory response, and antagonizing the occurrence and development of As.

摘要：
Developing a fluorescent probe for UO22+, which is resistant to interference from other ions such as Cu2+ and can be applied in acidic and high-water systems, has been a major challenge. In this study, a "turn-off" fluorescent probe for triamine-modified flavonoid derivatives, 2-triphenylamine3-hydroxy-4H-chromen-4-one (abbreviated to HTPAF), was synthesized. In the solvent system of dimethyl sulfoxide:H2O (abbreviated to DMSO:H2O) (v/v = 5:95 pH = 4.5), the HTPAF solution was excited with 364 nm light and showed a strong fluorescence emission peak at 474 nm with a Stokes shift of 110 nm. After the addition of UO22+, the fluorescence at 474 nm was quenched. More importantly, there was no interference in the presence of metal ions (Pb2+, Cd2+, Cr3+, Fe3+, Co2+, Th4+, La3+, etc.), especially Cu2+ and Al3+. It is worth noting that the theoretical model for the binding of UO22+ to HTPAF was derived by more detailed density functional theory (DFT) calculations in this study, while the coordination mode was further verified using HRMS, FT-IR and (HNMR)-H-1, demonstrating a coordination ratio of 1:2. In addition, the corresponding photo-induced electron transfer (PET) fluorescence quenching mechanism was also proposed.

摘要：
In this paper, we investigate the instabilities of the rotation-thermocapillary-buoyancy driven flow in the Czochralski model versus diverse aspect ratios (gamma = depth/radius) by linear stability analysis based on the spectral element method, concerning the cases of dimensionless crystal-rotating rate omega(s) = 265 and omega(s) = 300. Besides, we provide physical insight into the instability mechanisms of the mixed convection by energy analysis. For the omega(s) = 265 case, we observe two types of propagation modes of hydrothermal waves, while in the case of omega(s) = 300, there exists only one propagation mode. Moreover, in the former case, the critical wave number changes from 1 to 2 and back to 1 with the decrease of aspect ratio, accompanied by the jumps of critical frequency. In the case of omega(s) = 265, flow instability for propagation I is caused by inertial force, whilst that for propagation II attributes to thermal buoyancy. The physical instability mechanism of omega(s) = 300 case is essentially the linking between the mechanisms of buoyancy and inertial instabilities.

Methods: Medical records of patients with necrotizing fasciitis, treated in our hospital from June 2019 to June 2021, were selected. Patients were retrospectively assigned into two groups based on the debridement method used: debridement with silver ion sterilization nursing solution Group-I, or debridement with negative pressure sealing drainage technology combined with silver ion sterilization nursing solution. Group-II. Wound healing, dressing change times, healing time, treatment cost and patient satisfaction in both groups were statistically compared. Results: The wound healing rate of patients in Group-II group was higher than that of Group-I on the 5th, 10th and 15th day after operation (P < 0.05). Dressing change times, healing time and treatment cost of patients in the Group-II were lower than those of Group-1 (P < 0.05). Patient satisfaction in the Group-II was 91.4% (54 / 59), which was higher than that of Group-I (75.4% (40 / 53) (P < 0.05). Conclusions: Negative pressure sealing drainage technology combined with silver ion sterilization nursing solution in the nursing of necrotizing fasciitis is effective. It can promote wound healing, shorten the healing time, reduce the times of wound dressing change and treatment cost. It also improves the overall patient satisfaction, making it an efficient method in clinical application.

摘要：
Reactive oxygen species (ROS) can kill cancer cells in tumor therapy. However, the anticancer efficacy of ROS is generally suppressed by the reductive press in tumor microenvironment (TME). Herein, lysozyme (LZM) modified black phosphorous (BP) /manganese dioxide nanosheets (LZM@BP/MnO2 NSs, LBM) as an effective and biocompatible nanodrug platform for synergistic photodynamic-/radio- therapy are prepared. The controllable preparation of negatively charged MnO2 NSs is achieved through biomimetic mineralization strategy using bovine serum albumin (BSA) as a template. To facilitate the loading of BP on MnO2, lysozyme is used to modify BP to obtain positively charged BP NSs. The as-obtained LBM possess higher biostability and exhibit superior ROS generation efficiency to BP, owing to the alleviation of reductive species (i.e., GSH) in TME by the oxidation of MnO2. Moreover, LBM can be easily decomposed in the tumor sites, leading to the good biocompatibility both in vitro and in vivo. The amplified intracellular ROS generation properties of LBM assisted combination of photodynamic therapy and radiotherapy ultimately boost the synergistic therapeutic efficacy against cancer.

摘要：
Metastasis of breast cancer have caused the majority of cancer-related death worldwide. The circRNAs are associated with tumorigenesis and metastasis in breast cancer according to recent research. However, the biological mechanism of circRNAs in liver metastatic breast cancer remains ambiguous yet. Microarray analysis of three pairs of primary BC tissues and matched hepatic metastatic specimens identified circEZH2. We used RT-qPCR and FISH assays to confirm circEZH2 existence, characteristics, and expression. Both in vivo and in vitro, circEZH2 played an oncogenic role which promoted metastasis as well. A range of bioinformatic analysis, Western blot, RNA pull-down, RIP, ChIP, and animal experiments were used to define the feedback loop involving FUS, circEZH2, miR-217-5p, KLF5, FUS, CXCR4 as well as epithelial and mesenchymal transition. In our research, circEZH2 was proved to be upregulated in liver metastases in BC and predicted the worse prognosis in breast cancer patients. Overexpression of circEZH2 notably accentuated the vitality and invasion of BC cells, whereas knockdown of circEZH2 elicited the literally opposite effects. Besides, overexpressed circEZH2 promoted tumorigenesis and liver metastasis in vivo. Moreover, circEZH2 could adsorb miR-217-5p to upregulate KLF5 thus leading to activate FUS transcription which would facilitate the back-splicing program of circEZH2. Meanwhile, KLF5 could upregulated CXCR4 transcriptionally to accelerate epithelial and mesenchymal transition of breast cancer. Consequently, a novel feedback loop FUS/circEZH2/KLF5/CXCR4 was established while circEZH2 could be novel biomarker and potential target for BC patients’ therapy.

摘要：
Different fractures exist widely in rock mass and play a significant role in their deformation and strength properties. Crack rocks are often subjected to dynamic disturbances, which exist in many fields of geotechnical engineering practices. In this study, dynamic compression tests were carried out on rock specimens with parallel cracks using a split hopkinson pressure bar apparatus. Tests determined the effects of strain rate and crack intensity on dynamic responses, including progressive failure behavior, rock fragmentation characteristics, and energy dissipation. Based on the crack classification method, tensile-shear mixed cracking dominates the failure of rock specimens under the action of impact loading. Increasing the flaw inclination angle from 0 degrees-90 degrees changes the predominant cracking mechanism from tensile cracking to mixed tensile-shear cracking. The larger the loading rate, the more obvious the cracking mechanism, which indicates that the loading rate can promote the cracking failure of rock specimens. The fragmentation analysis shows that rock samples are significantly broken at higher loading rates, and higher loading rates lead to smaller average fragment sizes; therefore, the larger the fractal dimension is, the more uniform the broken fragments of smaller sizes are. Energy utilization efficiency decreases while energy dissipation density increases with increasing strain rate. For a given loading rate, the energy absorption density and energy utilization efficiency first decrease and then increase with increasing flaw inclination, while the rockburst tendency of rock decreases initially and then increases. We also find that the elastic-plastic strain energy density increases linearly with the total input energy density, confirming that the linear energy property of granite has not been altered by the loading rate. According to this inherent property, the peak elastic strain energy of the crack specimen can be calculated accurately. On this basis, the rockburst proneness of granite can be determined quantitatively using the residual elastic energy index, and the result is consistent with the intensity of actual rockburst for the specimens.
摘要：
The uraniferous caustic sludge (UCS) produced in the production of uranium fuel components was hardly to leach directly, due to its very low-grade uranium(<10%). A two-step operation, consisting of the three-stage countercurrent dissolution and subsequent H2SO4 curing processes, was conducted to deal with UCS. The results of the three-stage countercurrent dissolution process showed that the uranium content in UCS was decreased from 8.66 to 1.06%, the residual ratio was less than 18%, and the leaching rate of uranium was 98% or more. The results of H2SO4 curing process showed that the leaching rate of uranium could be controlled at more than 99.9%, and the uranium content of UCS was decreased to 0.19%. The process may serve the purpose of recovering uranium from uranium-containing alkaline residues with complex source.
