    Abstract Renal tubular epithelial cells are one of the essential functional cells in the kidney. Optimizing the isolation and culture method of primary renal tubular epithelial cells from SD mammary rats provides better experimental materials for renal tubule-related studies, which is essential for studying the pathogenesis of renal diseases, especially diabetic nephropathy and drug screening. SD rat renal tubular epithelial cells were isolated and purified by 2.5-mg/ml collagenase II or 2 mg/ml trypsin + 2.5 mg/ml collagenase II enzymatic digestion. The isolation and purification were observed at different time points (15 min, 30 min, 45 min, and 60 min) to determine the optimal extraction time for the enzymatic digestion method. After comparing the two enzymatic methods, it was determined that the trypsin + collagenase II enzymatic method was more effective. The primary renal tubular epithelial cells extracted by the trypsin + collagenase II digestion method were identified by the marker Cytokeratin 18 of renal tubular epithelial cells at 45 min of digestion with high purity. We established a simple, efficient, and reproducible method for isolation and culture of renal tubular epithelial cells in SD mammary gland rats.

    Abstract A capillarity-induced negative pressure is of general importance for understanding the phase behaviors of liquids in small pores and cracks. A unique example is the embolism in the xylem of plants and the cavitation at the limiting negative pressure generated by evaporation of water from nanocapillaries in the cell walls of leaves. In this work, by combining the effect of a capillary and cavitation together, we demonstrate with molecular dynamics (MD) simulations that capillarity is able to induce spontaneous cavitation in the presence of hydrophobic heterogeneities. Our simulation results reveal separately how the capillary generates a negative pressure and how the generated negative pressure affects the onset of cavitation. We then interpret the cavitation mechanism and determine the occurrence of cavitation as a function of the hydrophobicity of the nucleating substrates where the cavitation initiates and as a function of the hydrophilicity of the capillary tube from which the negative pressure generates. Our results reveal that the capillary-induced cavitation can be described well with a heterogeneous nucleation mechanism, within the framework of classical nucleation theory.

    Abstract Objective: Thrombocytopenia is commonly associated with infectious diseases and serves as an indicator of disease severity. However, reports on its manifestation in conjunction with
    Materials and methods: A retrospective analysis of the clinical data from patients with KPLA admitted between June 2012 and June 2023 was performed. Baseline characteristics, biochemical assessments, therapeutic interventions, complications, and clinical outcomes were compared between patients with and without thrombocytopenia. To investigate the potential etiologies underlying thrombocytopenia, the association between platelet count reduction and thrombophlebitis was examined, with a particular focus on platelet consumption. Furthermore, bone marrow aspiration results were evaluated to assess platelet production anomalies.
    Results: A total of 361 KPLA patients were included in the study, among whom 60 (17%) had concurrent thrombocytopenia. Those in the thrombocytopenia group exhibited significantly higher rates of thrombophlebitis (p = 0.042), extrahepatic metastatic infection (p = 0.01), septic shock (p = 0.024), admissions to the intensive care unit (p = 0.002), and in-hospital mortality (p = 0.045). Multivariate analysis revealed that thrombocytopenia (odds ratio, 2.125; 95% confidence interval, 1.114-4.056; p = 0.022) was independently associated with thrombophlebitis. Among the thrombocytopenic patients, eight underwent bone marrow aspiration, and six (75%) had impaired medullar platelet production. After treatment, 88.6% of thrombocytopenic patients (n = 47) demonstrated recovery in their platelet counts with a median recovery time of five days (interquartile range, 3-6 days).
    Conclusions: Thrombocytopenia in patients with KPLA is indicative of increased disease severity. The underlying etiologies for thrombocytopenia may include impaired platelet production within the bone marrow and augmented peripheral platelet consumption as evidenced by the presence of thrombophlebitis.

    Abstract Through employing molecular dynamics, in this work, we study how a two-component surfactant mixture cooperatively reduces the interfacial tension of a flat vapor-liquid interface. Our simulation results show that in the presence of a given insoluble surfactant, adding a secondary surfactant would either further reduce interfacial tension, indicating a positive synergistic effect, or increase the interfacial tension instead, indicating a negative synergistic effect. The synergism of the surfactant mixture in lowering surface tension is found to depend strongly on the structure complementary effect between different surfactant components. The synergistic mechanisms are then interpreted with minimization of the bending free energy of the composite surfactant monolayer via cooperatively changing the monolayer spontaneous curvature. By roughly describing the monolayer spontaneous curvature with the balanced distribution of surfactant heads and tails, we confirm that the positive synergistic effect in lowering surface tension is featured with the increasingly symmetric head-tail distributions, while the negative synergistic effect is featured with the increasingly asymmetric head-tail distributions. Furthermore, our simulation results indicate that minimal interfacial tension can only be observed when the spontaneous curvature is nearly zero.

    Abstract Background: Chronic subdural hematoma (CSDH) is a common disease in neurosurgery department. Burr-hole drainage is the main surgical treatment. And the recurrence rate is as high as 25%.
    Case report: In this case, a male patient with CSDH in the left frontotemporal parietal region underwent 2 drilling and drainage operations in the local hospital, but the hematoma recurred after operations. Being unable to bearing the repeated and progressive aggravation of headache, he came to our hospital for treatment. After considering the comprehensive situation, we use a new surgical method, removal of hematoma by drilling multiple holes in the lateral skull, to cure the patient.
    Conclusions: We get inspirations from the treatment of moyamoya disease surgery, through the bone holes the scalp forms many "meat column" like structures which have powerful capability in absorption, so the scalp could deep into the hematoma, then the CSDH could be cured. Provide a new surgical method for the treatment of refractory CSDH.

    Abstract This paper presents experimental investigations on aerodynamic performance of a ducted coaxial-rotor system to evaluate its potential application as a small unmanned aerial vehicle (SUAV). Aimed at determining the influence of design parameters (rotor spacing, tip clearance and rotor position within the duct) on hover performance, a variety of systematic measurements for several correlative configurations (single/coaxial rotor with or without a duct) in terms of thrust and torque, as well as power, were conducted in an attempt to identify a better aerodynamic configuration. The experimental results for the coaxial-rotor system indicated that varying rotor spacing affected the thrust-sharing proportion between the two rotors, but this had no significant effect on the propulsive efficiency. The optimal H/R ratio was identified as being 0.40, due to a larger thrust and stronger stability in the case of identical rotation speeds. As for the ducted single-rotor configuration, the tip clearance played a dominant role in improving its thrust performance, especially for smaller gaps (δ≤0.015R), while the rotor position made subordinate contributions. The maximum performance was obtained with the rotor located at the P
