ABSTRACT
Background: Traditional association studies of cardiovascular disease (CVD) categorizations and polyunsaturated fatty acids (PUFAs) yielded conflicting findings. We propose a novel classification system based on fundamental characteristics of cardiovascular patients, such as age, body mass index, waist-hip ratio, to more accurately assess the impact of PUFAs (plasma measures) such as omega (ω)-3 (n-3) and ω-6 on mortality in cardiovascular patients. Methods: Principal component analysis and k-means clustering were used to determine the CVD subtype. Variables included age, body mass index, waist-hip ratio, diastolic blood pressure, systolic blood pressure, total cholesterol, total triglycerides, high-density lipoprotein-cholesterol, apolipoprotein B:apolipoprotein A1, glycated hemoglobin, creatinine, albumin, C-reactive protein, white blood cell count, platelet count, and hemoglobin concentration. The association of PUFAs with all-cause, cardiovascular, and ischemic heart disease (IHD) mortality in patients with CVD was prospectively evaluated using restricted cubic splines and Cox proportional risk models. Results: Among the 35,096 participants, 3,786 fatalities occurred. Three distinct CVD subtypes were identified, with cluster 3 characterized by older age, male gender, and low high-density lipoprotein-cholesterol, having the highest risk of mortality. Clusters 2 and 3 had the highest DHA and ω-6/ω-3 ratios, respectively, compared with Cluster 1. The protective effects of total PUFAs, ω-3, and DHA were mainly reflected in all-cause mortality and were more significant in clusters 2 and 3. Furthermore, the ω-6/ω-3 ratio of the highest quartile increased risk of all-cause [Q3: hazard ratio (HR): 1.14, 95% confidence interval [CI]: 1.00, 1.29; Q4: HR: 1.41, 95% CI: 1.24, 1.61], CVD (Q4: HR: 1.36, 95% CI: 1.07, 1.75), and IHD mortality (Q4: HR: 1.17, 95% CI: 1.12, 2.03) in cluster 3 compared with the first quartile. Conclusions: Our findings highlight the heterogeneity of associations observed for the same type of PUFAs across distinct clusters. This association may be elucidated by the intricate interplay of various factors, encompassing inflammation, lipid metabolism, and cardiovascular health.
ABSTRACT
Here, we present complete chromosome sequences of Borrelia miyamotoi samples CZ-F1E and CZ-F190E, which were obtained from Ixodes ricinus eggs from Czechia. The chromosome sequences, assembled from Illumina and Sanger sequencing data, had average coverage values of 647× and 3,216×, respectively. They belong to the European genotype, distinct from the Asian and American strains.
ABSTRACT
Objective To develop a HIS architecture based on.NET in C/S environment,so that the different functional modules of the HIS can be easily loaded into the architecture to improve the efficiency of HIS development and reduce development costs.Methods The proposed HIS architecture underwent hierarchical structure design,and was composed of boundary,logic,data access and physical layers.The user input data through the boundary layer,responded to the user request through the logic layer,and reacted to the request from the logic layer through the data access layer to realize database access.The boundary,logic and data access layers transferred data through the physical layer which was used as the data carrier.C# language of Visual Studio 2008 was applied to the development of the architecture program.Results The system could conveniently load each function module in HIS of the hospital,which greatly facilitated the developer to control the function of the program.Conclusion The system meets the requirements of medical staff and management to the software,improves the efficiency of HIS system development,and reduces the cost of system development.
ABSTRACT
Lectin from green marine algae Enteromorpha intestinalis (EIL) was isolated by extraction with PBS, followed by ammonium sulfate fraction and a combination of ion-exchange chromatography on DEAE-52 fiber and gel filtration on SephadexG-200. Lectin showed single band on both PAGE and isoelectrofocusing electrophoresis. Its isoelectric point was 8.9 and molecular weight was 17783 tested on SephadexG-200. EIL displayed some agglutination activities with Chlamydomonas and erythrocytes of rabbit, common carp, crucian carp and human (A, B, AB, O), but the maximum agglutination was with crucian carp. The hemagglutinating activity for rabbit erythrocyte could not be inhibited by D-fructose, D-galactose, glucose, sucrose, mannose, lactose, bovine-thyroglobulin, egg albumin and gamma-globulin. The hemagglutinating activity of lectin would be showed at pH 4.0~10.2, and more potent at pH 6.9~8.0. The hemagglutinating activity was not affected at 90℃ for 1h, so it could be said that the lectin had high heat resistance.
