    In: Journal of Sandwich Structures & Materials, SAGE Publications, Vol. 23, No. 5 ( 2021-06), p. 1427-1452
    Abstract: In recent years, composite materials have been more widely used in sandwich structures, which have been proved better performance in sandwich structures than other materials in some cases. In this paper, an analytical model is developed to predict the key stress, failure modes, and failure loads of the composite corrugated-core sandwich structures under three-point bending in both longitudinal and transverse directions. Then a three-dimensional finite element model by using Hashin’s model to predict fiber composite laminates and cohesive zone model to predict extra epoxy layer of fiber composite laminates is developed and validated by the corresponding experiments. The analytical model is also validated through both simulation and experiment. Finally, the failure mechanism maps and effects of orientation angles on failure have been further studied based on the analytical model.

    Abstract: The effect of polyomavirus infection in HSCT recipients is poorly understood. Methods We evaluated 38 HSCT recipients. Polyomavirus was detected by nested qualitative polymerase chain reaction (PCR) assays of urine. The risk factors for BK virus and JC virus were analysed. The kidney and liver functions of infected and uninfected patients were compared. Results BK virus, JC virus, and simian virus 40 were detected in 21%, 42%, and 0% of HSCT recipients respectively. HCMV infection was found to be an independent risk factor for JC virus infection (odds ratio (OR): 8.528), while transplants with mismatched HLA are more susceptible to BK virus infection (OR: 12.000). Liver function of JC virus-infected subjects was worse than that of uninfected subjects. Conclusion We must be vigilant for opportunistic polyomavirus infections in HSCT recipients, especially those with HCMV co-infection or a mismatched HLA transplant. When unexplained liver function deterioration is observed, JC virus infection should be considered.

    Abstract: Both smartphone addiction and phubbing are emerging behavioral problems. The present study investigates potential risk and protective factors of smartphone addiction and phubbing behavior, including demographic factors, personal factors, and interpersonal factors among Chinese college students. A total of 866 college students (M age = 21.01, SD = 1.60) completed self-reported questionnaires in classroom settings. Collected data were analyzed by using Pearson’s correlation and hierarchical linear regression analyses. The risk factors for smartphone addiction were phubbing behavior, depression, and social anxiety, while the protective factors were self-control and sense of security. In addition, the risk factors for phubbing behavior included female sex and smartphone addiction, while the protective factors included sense of security and interpersonal adaptability. Our findings help to enhance understanding of the general and specific risks and protective factors for smartphone addiction and phubbing behavior, which can benefit intervention development for related behavior prevention and reduction.

    Abstract: There is still a lack of effective biomarkers for the prediction of the risk of bleeding events among patients with nonvalvular atrial fibrillation (NVAF) taking dabigatran. This study aimed to investigate the association between change in total bilirubin (CTBIL) and risk of bleeding among patients with NVAF taking dabigatran. The CTBIL was the difference in serum total bilirubin at out of follow-up from baseline serum total bilirubin. A total of 486 patients with NVAF treated with dabigatran (110 mg twice daily) were recruited from 12 centers in China from February 2015 to December 2017. All patients were followed for 3 months. Cox proportional hazards regression analysis was used to evaluate the association between the CTBIL and bleeding. Moreover, a Cox proportional hazards regression with cubic spline functions and smooth curve fitting (the penalized spline method) and 2 piecewise Cox proportional hazards models were used to address the nonlinearity between CTBIL and bleeding. The mean (SD) follow-up duration was 81.2 (20.2) days. In all, 67 patients experienced bleeding events. A U-shaped association was observed between the CTBIL and bleeding, with increased hazard ratios (HRs) in relation to either low or high CTBIL levels. For CTBIL 〈 6.63 µmol/L, the HR (95% confidence interval [CI]) was 0.90 (0.84-0.96), and for CTBIL ≥6.63 µmol/L, the HR (95% CI) was 1.35 (1.14-1.60). Our findings showed a U-shaped relationship between CTBIL and bleeding. Both low and high levels of CTBIL were associated with a higher risk of bleeding.

    Abstract: Ovarian cancer (OC) is the most lethal gynecologic cancer, and the incidence of OC has risen steadily worldwide. Numerous microRNAs (miRNAs) have been found to be involved in the progression of OC. miR-204-5p is down-regulated and functions as a tumor suppressor in various types of human malignant tumors. However, the biological roles and molecular mechanisms of miR-204-5p in OC still remain unclear. In this study, the aberrant down-regulation of miR-204-5p was detected in OC tissues. We also observed that miR-204-5p overexpression represses OC cell proliferation. Ubiquitin-specific peptidase 47 (USP47) is verified as the functional target of miR-204-5p, through which it plays an important biological role in OC. Our results uncover new functions and mechanisms for miR-204-5p in the progression of OC, and provide a potential therapeutic target for the treatment of OC.

    Abstract: Chronic pain (CP) adversely impacts people’s health. However, the influence of CP on pregnant women and their fetuses remains unclear. Few reasonable interventions have been offered to these women. This study aimed to examine the effects of enriched environmental intervention (EEI) on the delivery outcome and offspring health of pregnant mice with CP. Forty pregnant mice were equally and randomly divided into four groups (control, sham, CP, and CP + EEI). Monoarthritis was induced by subcutaneous injection of the complete Freund’s adjuvant (100 μg/100 μl) into the left hind paw of mice on Day 0 of gestation. Sham mice received 100 µl of sterile phosphate-buffered saline subcutaneously. General health status and delivery outcomes of pregnant mice and general physical status, growth, and development of offspring were observed and compared between groups. CP mice exhibited less weight gain, higher rate of premature delivery, smaller litter size, lower live birth rate, lower filial birth weight, shorter filial tail length, and lower filial rates of achieving righting reflex and crawling compared to mice in the control/sham/CP + EEI groups. There were no significant differences between mice in the CP + EEI group and those in the control and sham groups. CP during pregnancy led to serious adverse impacts on both the mother and fetus mice in this study, and EEI was an effective treatment for these effects.

    Abstract: To explore the expressions of annexin A2 in bladder cancer cell lines and bladder cancer tissues, we want to find the relationship among annexin A2, drug resistance, and recurrence of bladder cancer. Methods: Our laboratory established the PUMC-91 bladder cancer cell line against gradient concentration of Adriamycin (0.3, 0.6, and 1.0 μg/mL), and we also collected 60 cases of surgically resected bladder cancer recurrent tissue samples. The tissues were classified into 2 groups according to the frequency of recurrence ( 〈 6 months and 〉 2 years) after initial surgery. The method of immunohistochemistry was used to examine the differences in the expression of annexin A2. Results: There were statistical differences in annexin A2 among normal bladder epithelial cell line SV-HUC-1, PUMC-91, PUMC-91 against 0.3 μg/mL Adriamycin, and PUMC-91 against 1.0 μg/mL Adriamycin ( P 〈 .05). The expressions of Annexin A2 were found to be higher than those that recurred at 〉 2 years ( P = .002) in the bladder cancer tissues and that recurred at 〈 6 months after initial surgery. It was also associated with invasion depth (stage) of bladder cancer, such as higher expression in T2 (invasive muscular) group than Tis (carcinoma in situ) and T1 (invasive mucosa lamina propria) groups ( P = .003 and P = .000, respectively). But, it did not correlate with the differentiation (grade) of cancer cells in bladder cancer tissues ( P = .593). Conclusion: Annexin A2 can act as a valuable biomarker for predicting the drug resistance and recurrence of bladder cancer.

    Abstract: Previous studies reported that the aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AST/ALT) was a risk factor in cardiovascular disease. Peripheral artery disease (PAD) is an important risk factor for cardiovascular death. However, only a few studies investigated the correlations between the AST/ALT ratio and PAD. We analyzed data from 10 900 patients with hypertension from the Chinese Hypertension Registry Study; 350 patients had PAD (prevalence 3.2%). After adjusting for potential confounders, the AST/ALT ratio was independently and positively associated with risk of PAD (OR: 1.31, 95% CI, 1.13-1.59), and a significant increased risk of PAD for the third AST/ALT ratio tertile (T3) compared with the first tertile (T1; OR: 1.49, 95% CI, 1.09-2.04, P trend = .005) was found. Moreover, when we combined T1 and T2 into one group and used it as a reference group, the risk of PAD increased with the increase in AST/ALT; the risk ratio was 1.52 (95% CI, 1.20-1.95). A higher AST/ALT ratio (≥1.65) was associated with PAD risk in Chinese adults with hypertension. Our results suggest that the AST/ALT ratio may help identify patients at high risk of vascular end points and might be a convenient, economical, and effective tool for evaluating the risk of atherosclerosis.

    Abstract: Existing studies on tourism seasonality have been mainly identified at annual or monthly level and the seasonality in tourism demand forecasting has always been addressed by modeling season patterns. However, annual or monthly seasonality is coarse-grained and can’t capture the subtle changes emerging both in tourism theory and practice. This study recognizes tourism seasonality based on intra-day patterns and inter-day similarity and suggests a novel approach to addressing seasonality in tourism demand forecasting. The proposed three-step method contains tourism seasonality recognition, tourism seasonality matching, and tourism demand forecasting. The empirical findings, based on two attractions in China, demonstrate that the proposed method based on dynamic time warping and density-peak clustering can precisely capture tourism seasonality at the daily level. The method can also detect special tourism periods or subtle changes in seasonality, such as staggered peak travel phenomenon. Superior forecasting performance with seasonality matching is also revealed. This study sheds new light on tourism seasonality recognition and contributes to forecasting methodology.
