This review addresses the issues of low consumer engagement and market development difficulties in intangible cultural heritage (ICH) products. Dietary ICH products are selected as research materials to discover contemporary commercial survival paths for ICH through the psychological effects of advertising. Firstly, this study examines the respective advantages of rational and emotional ICH advertisement in terms of emotional responses, cognitive responses, attitudes, recall, and recognition. Then, it explores the effects of different ICH advertisement types (rational advertisement, emotional advertisement) and different degrees of situational involvement (purchasing for oneself, purchasing gifts for others) on the advertising effectiveness, aiming to identify factors influencing the psychological effects of ICH advertisement. Through statistical analysis, the main conclusions are as follows: (1) Rational ICH advertisement prompts consumers to consider the actual attributes of ICH products, leading to a more positive purchasing attitude. (2) Emotional ICH advertisement is more effective in eliciting positive emotions from consumers and enhancing brand memory. (3) Under the scenario of purchasing a gift for others, emotional ICH advertisement has a more positive impact on consumers' attitudes towards advertising. (4) Under different degrees of situational involvement, rational ICH advertisement has a more positive impact on consumers' purchasing attitudes. This study not only provides guidance for optimizing ICH advertising strategies but also offers new directions for market expansion, contributing valuable insights into cultural heritage preservation, as well as the development and protection of ICH.

Abstract: Objective: Chronic ischemia is associated with alterations in genes that result in myocardial remodeling. An important biochemical basis of cardiac remodeling is generation of reactive oxygen species (ROS). A few studies have suggested that acute ischemia triggers signals for remodeling. We examined the hypothesis that targeted deletion of lectin-like oxidized-LDL receptor (LOX-1) may inhibit signals related to cardiac remodeling. Methods and results: We generated LOX-1 knockout (KO) mice on C57BL/6 (wild-type mice) background, and subjected wild-type and KO mice to ischemia–reperfusion (I–R). The wild-type mice developed a marked reduction in left ventricular systolic pressure and ±dp/dtmax and an increase in left ventricular end-diastolic pressure following I–R, and this change was much less in the LOX-1 KO mice, indicating preservation of left ventricular function with LOX-1 deletion. There was evidence for marked oxidative stress (NADPH oxidase expression, malondialdehyde and 8-isoprostane) following I–R in the wild-type mice, much less so in the LOX-1 KO mice (P <0.01). In concert, collagen deposition (Masson''s trichrome and Picro-sirius red staining) increased dramatically in the wild-type mice, but only half as much in the LOX-1 KO mice (P <0.01). Collagen staining data was corroborated with procollagen-I expression. Further, fibronectin and osteopontin expression increased in the wild-type mice, but to a much smaller extent in the LOX-1 KO mice (P <0.01). Conclusions: These findings provide compelling evidence that LOX-1 is a key modulator of cardiac remodeling which starts immediately following I–R. [Copyright &y& Elsevier]

Background: Coronavirus disease 2019 (COVID-19) is highly contagious and deadly and is associated with coagulopathy. Pentraxin-3(PTX3) participates in innate resistance to infections and plays a role in thrombogenesis., Purpose: The present study aimed to investigate the role of PTX3 in coagulopathy in patients with COVID-19., Methods: A retrospective study, including thirty-nine COVID-19 patients, enrolled in Hunan, China, were performed. The patients were classified into the D-dimer&#95;L (D-dimer <1mg/L) and D-dimer&#95;H (D-dimer≥1mg/L) groups basing on the plasma D-dimer levels on admission. Serum PTX3 levels were detected by enzyme-linked immunosorbent assays and compared between those two groups, then receiver operating characteristic (ROC) curve analysis, correlation analysis, and linear regression models were performed to analyze the association between PTX3 and D-dimer., Results: Our results showed that serum PTX3 levels (median values, 10.21 vs. 3.36, P <0.001), computerized chest tomography (C.T.) scores (median values, 10.0 vs. 9.0, P <0.05), and length of stay (LOS) (mean values, 16.0 vs. 10.7, P =0.001) in the D-dimer&#95;H group were significantly higher than that in D-dimer&#95;L group. ROC curve analysis revealed that the AUC of white blood corpuscle counts, C-reaction protein, erythrocyte sedimentation rate, and PTX3 for COVID-19 were 0.685, 0.863, 0.846, and 0.985, respectively. Correlation analysis showed that there was a positive relationship between PTX3 and D-dimer (r=0.721, P <0.001), chest CT imaging score (r=0.418, P =0.008), and LOS (r=0.486, P =0.002). Multiple linear regression analysis showed that the coefficient of determination was 0.657 ( P < 0.001)., Conclusion: Serum level of PTX3 was positively correlated with disease severity and coagulopathy. Detection of serum PTX3 level could help identify severer patients on admission and may be a potential therapeutic target for coagulopathy in patients with COVID-19., Competing Interests: Competing interests: The authors declare no conflict of Interest.

Corosolic acid is clinically proven to activate cell glucose-transporter "shuttles" and thus helps balance blood glucose levels. A method was developed for the determination of corosolic acid in Eriobotrya japonica leaves by reversed-phase high performance liquid chromatography (RP-HPLC). The peak of corosolic acid in Eriobotrya japonica leaves was qualitatively analyzed by comparing the retention times and mass spectra of corosolic acid standard and the extract on HPLC-mass spectrometry (MS). Eriobotrya japonica leaves were extracted thrice for 3.0 h at 90 degrees C with 90% ethanol. The extract was concentrated and deposited by water to remove the impurity which interfered the determination. The deposit was dissolved by methanol and separated on an ODS column (250 mm x 4.6 mm i.d., 5 microm). Methanol-1.0% acetic acid (88:12, v/v) was used as the mobile phase with a flow rate of 0.8 mL/min. The detection wavelength was 215 nm. The linearity was good within the range of 1.0-6.0 microg (r = 0.9999). The corosolic acid content of Eriobotrya japonica leaves from Huangshan was 0.36%. The average recovery of corosolic acid was 99%. The method is simple, rapid, accurate and reliable for the determination of corosolic acid in Eriobotrya japonica leaves.
