SUMMARY OBJECTIVE: The objective of this study was to explore the relationship between serum soluble fms-like tyrosine kinase 1 and the severity of acute pancreatitis and its diagnostic utility. METHODS: This study was carried out by searching Chinese and English literature from the establishment of the database to July 9, 2023, systematically, and assessing the quality and heterogeneity of the articles included. RESULTS: Thirteen studies with a total of 986 patients were included. Patients with severe acute pancreatitis showed higher levels of soluble fms-like tyrosine kinase 1 compared with mild acute pancreatitis [weighted mean difference=76.64 pg/mL, 95% confidence interval (95%CI 50.39–102.89, p<0.001)]. Soluble fms-like tyrosine kinase 1 predicted pooled sensitivity, specificity, and area under the curve were 79%, 74%, and 0.85 for severe acute pancreatitis, with some heterogeneity (I2>50% or p<0.05). In the subgroup analysis, cutoff >150 pg/mL was found to be a heterogeneous factor. CONCLUSION: Soluble fms-like tyrosine kinase 1 is a reliable tool for identifying acute pancreatitis severity, but only as a screening tool.

Abstract Introduction: non-alcoholic fatty liver disease (NAFLD) is a disease in which there is excessive fat deposition in hepatocytes due to hepatoprotective factors. Objectives: to assess the association of the triglyceride-glucose index with the occurrence of non-alcoholic fatty liver disease and mortality in elderly inpatients. To identify the TyG index as a predictive factor of NAFLD. Methods: this prospective observational study included elderly inpatients admitted to the Department of Endocrinology at the Linyi Geriatrics Hospital, Affiliated to Shandong Medical College, between August 2020 and April 2021. The TyG index was calculated according to an established formula: TyG = Ln [triglycerides (TG) (mg/dl) × Fasting plasma glucose (FPG) (mg/dl) / 2]. Result: a total of 264 patients were enrolled, with 52 (19.7 %) cases occurred NAFLD. Multivariate logistic regression analysis showed that TyG (OR = 3.889; 95 % CI: 1.134-11.420; p = 0.014) and ALT (OR = 1.064; 95 % CI: 1.012-1.118; p = 0.015) were independently associated with the occurrence of NAFLD. Furthermore, receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) of TyG was 0.727, with sensitivity = 80.4 % and specificity = 57.8 % at cut off = 8.71. A Cox proportional hazards regression model showed that, after adjusting for age, sex, smoking, drinking, hypertension, and type 2 diabetes TyG > 8.71 (HR = 3.191; 95 % CI: 1.347 to 7.560; p < 0.001) was an independent risk factor for mortality in the elderly. Conclusions: the TyG index can predict non-alcoholic fatty liver disease and mortality in elderly Chinese inpatients.

Conclusiones: el índice TyG puede predecir la enfermedad del hígado graso no alcohólico y la mortalidad en pacientes chinos hospitalizados de avanzada edad.

ABSTRACT This paper discusses the design of a safflower picking robot control system and focuses on a navigation control subsystem based on multisensor fusion. A navigation subsystem, an identification and positioning subsystem, a picking subsystem, and a levelling subsystem are designed. The hardware and software of the navigation subsystem are designed in detail, and a multisensor fusion positioning method based on extended Kalman fusion technology is proposed. The accuracy and stability levels of different combined navigation methods are compared. To test the effectiveness and accuracy of the proposed method, an outdoor test is carried out. The test results show that the outdoor fusion positioning accuracy of the robot is less than 8 cm, and when the satellite signal is lost, the navigation control subsystem can still provide high positioning accuracy. The final positioning result obtained using the integrated positioning method of the wheel odometer + IMU + DGNSS is approximately 52% higher than that of the odometer, approximately 29% higher than that of the wheel odometer + IMU, and approximately 11% higher than that of the IMU + DGNSS. detail compared out cm lost 52 29 11 5 2 1

Abstract Oridonin is an enantiomer-kaurene tetracyclic diterpenoid compound, which is the main active component of Rabdosia rubescens, a herb used in traditional Chinese medicine. It has been reported to exert anti-tumor, anti-inflammatory, pro-apoptotic, anti-angiogenic, neuroprotective, and other pharmacological effects. Owing to the overuse of antibiotics, currently, the medical and food industries are facing drug resistance challenges, which have severely impacted food and medical safety. Thus, new antibacterial agents must be identified. As an important active component of Rabdosia rubescens, oridonin has been extensively and deeply studied in antimicrobial aspects. This paper reviews the antimicrobial activity of oridonin and its underlying mechanism. In addition, its safety and application as an antibacterial agent were briefly introduced. Finally, the current problems and challenges of the application of oridonin and the prospects were also elucidated. enantiomerkaurene enantiomer kaurene compound rubescens medicine antitumor, antitumor anti tumor, tumor anti-tumor antiinflammatory, antiinflammatory inflammatory, inflammatory anti-inflammatory proapoptotic, proapoptotic pro apoptotic, apoptotic pro-apoptotic antiangiogenic, antiangiogenic angiogenic, angiogenic anti-angiogenic neuroprotective effects antibiotics currently Thus identified aspects mechanism addition introduced Finally elucidated

Abstract Oridonin, a terpenoid with various biological functions, has limited uses in the functional food and pharmaceutical industries owing to its low water solubility. Previous studies have used cyclodextrin inclusion to improve its solubility. Herein, the effects of different cyclodextrins on the inclusion of oridonin were investigated using phase solubility and molecular docking tests. The binding constants of α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin with oridonin were 22.6, 298.6, and 317.4, respectively. The corresponding binding energies were -6.49, -6.76, and -7.53 kcal/mol, respectively, suggesting that the interaction between γ-cyclodextrin and oridonin was the strongest, thereby improving the solubility of oridonin to the greatest extent. Further experiments indicated that no new unsaturated bonds formed after oridonin complexed with γ-cyclodextrin. In addition, the complexation of oridonin with γ-cyclodextrin, led to its complete dispersal in an amorphous state that was thermally stable. This study promotes the application of oridonin in food and medicines.

Abstract The rheological properties of dough from modified Tartary buckwheat bran flour (MTBF) by heat-moisture treatment (HMT) and wheat flour (WF) were investigated in this study, and the application of MTBF in steamed bread processing was also evaluated. The results showed that the addition of MTBF had a significant effect on torque curve and parameters of the dough. With the increase of the weight proportion of MTBF in the blend (WMTBF), the water absorption of the dough gradually increased, the protein weakening degree decreased at first and then increased, and the dough had better kneading resistance when the WMTBF was 30% and 40%. With the increase of WMTBF, the color of the steamed bread gradually darkened and yellowed, and the specific volume declined gradually. In addition, the hardness, gumminess and chewiness of steamed bread increased with WMTBF, but its springiness, cohesiveness and resilience decreased. When WMTBF ≥ 20%, internal texture structure of steamed bread was enhanced. Sensory evaluation indicated that the steamed bread developed at WMTBF = 20% could obtain similar quality and pleasant appearance to common wheat steamed bread.

Abstract Three typical contaminant bacteria, namely, Gluconobacter, Acetobacter, and Lactobacillus, were selected from fermented milk. The strong specific genes were screened as target sequences, and the droplet digital polymerase chain reaction (ddPCR) amplification system and reaction conditions were optimized. We established a ddPCR detection method for the three kinds of bacteria in fermented milk and then verified the specificity and sensitivity of the method. Absolute quantitative results were also analyzed. Results showed that ddPCR detection method for the three contaminants was specific and sensitive, and that the lowest detectable concentrations of Gluconobacter, Bacteroides, and Lactobacillus plantarum were 8.8 × 100 CFU/mL, 8.9 × 101 CFU/mL, and 9.6 × 101 CFU/mL, respectively. The relationship between the quantitative analysis results and ddPCR test results was good, proving the feasibility of ddPCR for absolute quantitative detection. This manuscript reports on establishment of a ddPCR detection system for three bacterial contaminants in fermented milk. The ddPCR detection system has efficient detection of targeted bacterial contaminants in fermented milks that can be valuable to the dairy industry in terms of preventing economic loss due to microbial spoilage and associated quality defects.

Abstract To investigate the effect of DNMT3A in vascular calcification (VC) induced by high phosphorus. The arterial tissues of 12 patients with end stage renal disease (ESRD) and VC and 12 patients with ESRD without VC were collected. Rat vascular smooth muscle cells (VSMCs) were divided into control group, high phosphorus (P) group, P + DMSO group, p-ERK1/2 inhibitor group, DNMT3A group and DNMT3A + P group and P + shRNA-DNMT3A group. Vascular calcification was evaluated by von kossa staining. Cell calcification was evaluated by alizarin red staining. The calcium content was assessed by calcium determination kit. The levels of DNMT3A, Runx2, LC3 and p-ERK1/2 were significantly up-regulated in CKD patients with VC in comparison with those in CKD patients without VC(p<0.05). Moreover, the levels of SM22α and P62 were notably decreased in CKD patients with VC in comparison with those in CKD patients without VC(p<0.05). Similar changes were observed in VSMCs induced by high phosphorus. Knock down of DNMT3A in VSMCs inhibited phenotypic transformation and induced autophagy, then reduced calcification(p<0.05). Moreover, p-ERK1/2 level was downregulated by knock down of DNMT3A in comparison with the control group(p<0.05). In conclusion, DNMT3A regulated high phosphorus induced vascular medial calcification via ERK1/2 signaling.

Abstract We aimed to establish a method for the rapid identification of three common Gram-positive bacteria (Bacillus cereus, Listeria monocytogenes, and Micrococcus luteus) associated with foodborne diseases. MALDI-TOF-MS was used to determine the effects of sample pretreatment, culture medium, and culture time on the identification results. Then, MALDI-TOF-TOF-MS was used to establish an optimized method and further explore the effects of culture time on secondary proteins. Among the three sample pretreatment methods, formic acid extraction outperformed direct transfer and extended direct transfer, resulting in more protein peaks and higher peak intensity in B. cereus culture samples. However, with different culture times (1–7 d), ion peaks of all bacterial proteins were relatively stable according to MALDI-TOF-TOF-MS data. The protein peaks of B. cereus (1430 m/z), L. monocytogenes (2100 m/z), and M. luteus (2140 m/z) were split into small ion peaks at 1162, 1465, and 1625 m/z, respectively. After 7 d of culture, the secondary spectra, peak intensities, and peak values of formic acid-treated samples were relatively stable, indicating that secondary protein peaks were less affected by culture time. It provides a new approach for the routine identification and market supervision of food safety in China.

Abstract Objectives To explore the role and possible mechanisms of action of apolipoprotein O (APOO) in autophagy in Myocardial Infarction (MI) in vivo and in vitro. Methods Differential gene expression and single Gene Set Enrichment Analysis (GSEA) were used to evaluate MI-related candidate genes. Animal and cell MI models were established. Sh-APOO, si-APOO, and SB203580 were used to inhibit the expression of APOO or p38MAPK. Western blot and qRT-PCR were used to analyze the expression levels of the target protein or mRNA. Apoptosis was observed using the TUNEL assay. The plasma concentrations of CK-MB and cTn-I in humans and mice were determined. Results In the GSE23294 dataset, APOO mRNA was highly expressed in the left ventricle of mice with MI; GSEA revealed that APOO was positively correlated with p38MAPK, autophagy, and apoptosis. The plasma concentration of APOO in patients with MI was significantly higher than that in healthy subjects. The expression of APOO, Beclin-1, LC3, and Bax in mouse and AC16 cell MI models increased, while the level of Bcl-2 decreased. After silencing the APOO gene, the expression of APOO was downregulated; meanwhile, changes in autophagy, apoptosis and myocardial cell injury were reversed in vivo and in vitro. Furthermore, autophagy was alleviated after AC16 cells were treated with SB203580. Conclusions The increased APOO expression in mouse and cell MI models may activate autophagy and apoptosis by regulating the p38MAPK signaling pathway, thus aggravating the myocardial injury. HIGHLIGHTS APOO was highly expressed in the left ventricle of mice with myocardial infarction. Increasing of APOO may activate autophagy and apoptosis in myocardial infarction. The regulation of APOO in autophagy and apoptosis was regulated by p38MAPK signaling pathway.

Abstract With sodium trimetaphosphate as cross-linking agent, the cross-linked tigernut starch (CLTS) was prepared in this study. The effects of cross-linking on the structure and physicochemical properties of tigernut starch were also investigated. FT-IR analysis confirmed the formation of CLTS. X-Ray diffraction (XRD) results suggested that cross-linking not only retained the crystallization type of starch (C-type), but also enhanced the crystallinity. Compared with the native tigernut starch (NTS), CLTS had lower solubility and swelling power, the better syneresis and freeze-thaw stability. It was more prone to settlement. The pasting temperature and peak viscosity of CLTS were superior to those of NTS. It was easier to regenerate at low temperature, and its thermal stability was also significantly improved. Our results provide a reference for the in-depth development of tigernut starch.

Abstract Pickering high internal phase emulsion (HIPE) has a broad application prospect in the field of solid fat substitution and nutraceutical delivery, but the safe and available food-derived particle emulsifier is the bottleneck of its practical application. In this study, mung bean flour was used as a particle emulsifier to stabilize oil-in-water Pickering HIPEs. The results showed that the particle size of mung bean flour was suitable (median diameter, 26.41 μm) and had certain wettability. The volume fraction of oil phase (φ) and the concentration of mung bean flour (c) had significant effects on the formation of Pickering HIPEs. When c ≥ 1%, the Pickering HIPE of φ = 80% could be obtained. Mung bean flour not only played an emulsifying role at the oil/water interface, but also prevented the coalescence of oil droplets through its viscosity effect in the aqueous phase. With the increase of c, the droplet size of Pickering HIPEs decreased, the mechanical properties increased gradually, and the ability of HIPEs protecting β-carotene against ultraviolet irradiation was also enhanced.

Abstract Using fig leaves as raw materials, extraction time, extraction temperature, solid to liquid ratio, and ultrasonic power were selected as influencing factors to analyze their effects on the yield of fig leaf polysaccharides (FLPS). The response surface methodology was carried out to optimize the extraction parameters. Furthermore, the antioxidant activity of FLPS was studied. The experimental results show that the optimum extraction conditions are: extraction time of 121 min, extraction temperature of 72 °C, solid to liquid ratio of 1: 48 g/mL, and ultrasonic power of 250 W. In this case, the measured extraction rate of FLPS was 11.78%, which was in agreement with the theoretical extraction rate. Response surface analysis was used to accurately and reliably optimize the extraction of FLPS. The results of the antioxidant activity showed that FLPS had antioxidant activity. It has the best scavenging effect on ABTS radical cation (ABTS+·), and it also has ability to scavenge DPPH radical (DPPH·), hydroxyl radical (·OH), superoxide anion radical (·O2-), and ferric reducing activity. This study laid a theoretical foundation for the further development and application of FLPS.

Abstract Genetically modified soybean strains are trade monitoring object by China. Currently, the genetically modified soybean MON89788 has been approved in China to be imported as processing raw material. Therefore, there is an urgent need to establish a method to quantitatively assess MON89788. This study used droplet digital PCR technology to quantitatively detect MON89788. The results showed that the genomic DNA concentration and its copy number of genetically modified soybeans showed a certain linear relationship. The formula was y = 2.5967x + 3.1437, where R2 = 0.999. When the same 4.5% genetically modified sample was contained, the results of the droplet digital PCR ratio and linear methods were 5.88% and 3.599%, respectively. Comparing the two results showed that the droplet digital PCR ratio method has a larger error than the linear relationship method. The novel droplet digital PCR linear relationship method established in this study has high sensitivity and specificity, and thus is a good prospect for quantitative research.
