Background Diabetes mellitus is a global public health issue. Cross sectional studies have found that visceral fat is closely related to the prevalence of diabetes mellites, while prospective cohort studies on the trend of onset time of diabetes mellitus and its correlation with Chinese visceral adiposity index (CVAI) are scant. Objective To analyze the trend of onset time of diabetes mellitus and its correlation with CVAI in Pudong New Area, Shanghai, residents by the prospective cohort study, thus providing evidence for the scientific prevention and treatment of diabetes mellitus. Methods This was a prospective cohort study involving 5 236 residents from 12 townships and 35 village committees who participated in the chronic disease risk factor monitoring project in Pudong New Area, from January to July, 2013. Baseline data were collected, including CVAI, visceral adiposity index (VAI), body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), a body shape index (ABSI), and body adiposity index (BAI). Follow-up was conducted in 2016 and 2019. By the end of follow-up in October 2019, the incidence of new onset of diabetes mellitus in this cohort was calculated through questionnaire survey, laboratory testing, medical system visit information and vital statistics information system. According to the baseline quartile, the CVAI, VAI, BMI, WC, WHR, WHtR, ABSI, and BAI of the included population were divided into Q1 to Q4 quartiles. The number of cases in CVAI Q1-Q4 groups was 1 306, 1 307, 1 307, and 1 307, respectively. The number of cases in VAI Q1-Q4 groups was 1 300, 1 316, 1 306, and 1 306, respectively. The number of cases in BMI Q1-Q4 groups was 1 305, 1 302, 1 312, and 1 311, respectively. The number of cases in WC Q1-Q4 groups was 1 302, 1 273, 1 287, and 1 367, respectively. The number of cases in WHR Q1-Q4 groups was 1 180, 1 203, 1 332, and 1 514, respectively. The number of cases in WHtR Q1-Q4 groups was 1 199, 1 393, 1 400, and 1 237, respectively. The number of cases in ABSI Q1-Q4 groups was 1 316, 1 302, 1 302, and 1 308 respectively. The number of cases in BAI Q1-Q4 groups was 1 310, 1 304, 1 308, and 1 307, respectively. The multivariable Cox regression analysis was used to analyze the correlation of CVAI and other obesity indicators with the onset of diabetes mellitus. The predictive potential of CVAI and other obesity indicators in diabetes mellitus was assessed using receiver operator characteristic (ROC) curves. Results The incidence density of diabetes mellitus in Pudong New Area was 33.55/1 000 person-years from 2013 to 2016, and 23.25/ 1 000 person-years from 2017 to 2019. With aging, the total incidence density of diabetes mellitus showed an increasing trend (2013-2016: χ2=28.503, Ptrend

ObjectiveTo evaluate the intervention effect of meteorological risk forecasting service on acute onset and medical expenses of chronic obstructive pulmonary disease（COPD） patients， and to provide scientific basis for the establishment of health management model for chronic obstructive pulmonary disease（COPD） patients.MethodsStudy subjects were recruited from chronic obstructive pulmonary patients aged ≥40 in Pudong New Area. Propensity score matching method was used to determine the intervention group and the control group. The control group received regular health education and follow-up management， and the intervention group was provided with meteorological and environmental risk forecasting services through WeChat， mobile phone short message service（SMS）and telephone. Finally， a total of 2 589 subjects were included in the analysis， including 1 300 in the intervention group and 1 289 in the control group. General demographic data， past medical history and family history of COPD， COPD related knowledge and practice survey， COPD related symptom assessment， acute onset， health service utilization and medical expenses before and after intervention were collected through questionnaire survey. The differences of acute attack， health service utilization and related medical expenses between the two groups before and after intervention were compared to evaluate the intervention effect.ResultsIn terms of acute attacks， after intervention， the incidence of acute attacks in the intervention group was lower than that before intervention（χ2=52.901， P0.05）. After intervention， the difference between the control group and the intervention group with different intervention methods was statistically significant （H=11.864， P

Purpose: Investigate the oxylipin profiles in the aqueous humor of primary open-angle glaucoma (POAG) patients. Methods: Aqueous humor samples were collected from 17 POAG patients and 15 cataract subjects and subjected to a liquid chromatography/mass spectrometry (LC-MS) analysis to detect the oxylipins. The prediction potential of the differential abundant oxylipins was assessed by the receiver operating characteristic (ROC) curves. Pathway and correlation analyses on the oxylipins and clinical and biochemical parameters were also conducted. Results: The LC-MS analysis detected a total of 76 oxylipins, of which 29 oxylipins reached the detection limit. The multivariate analysis identified five differential abundant oxylipins, 15-keto-prostaglandin F2 alpha (15-kPGF2α), Leukotriene B4 (LTB4), 12,13-Epoxyoctadecenoic acid (12,13-Epome), 15-Hydroxyeicosatetraenoic acid (15-HETE) and 11-Hydroxyeicosatetraenoic acid (11-HETE). The five oxylipins are enriched in the arachidonic acid metabolism and linoleic acid metabolism pathways. Pearson correlation analysis showed that 11-HETE was positively correlated with intraocular pressure and central corneal thickness and negatively with cup/disk area ratio in the POAG patients. In addition, 15-kPGF2α was moderately and positively correlated with the mean deviation (MD) of visual field defect, and LTB4 was moderately and negatively correlated with macular thickness. Conclusions: This study revealed the oxylipin profile in the aqueous humor of POAG patients. Oxylipins involved in the arachidonic acid metabolism pathway could play a role in POAG, and anti-inflammatory therapies could be potential treatment strategies for POAG. [ABSTRACT FROM AUTHOR]

The Voronoi diagram on the Earth's surface is a significant data model, characterized by natural proximity and dynamic stability, which has emerged as one of the most promising solutions for global spatial dynamic management and analysis. However, traditional algorithms for generating spherical raster Voronoi diagrams find it challenging to dynamically adjust the Voronoi diagram while maintaining precision and efficiency. The efficient and accurate construction of the spherical Voronoi diagram has become one of the bottleneck issues limiting its further large-scale application. To this end, this paper proposes a dynamic construction scheme for the spherical Voronoi diagram based on the QTM (Quaternary Triangular Mesh) system, with the aim of enabling efficient generation, local updates, and multi-scale visualization of the spherical Voronoi diagrams. In this paper, canonical ordering is introduced. Tailored for the properties of the spherical triangular grid, it constructs a unified and standardized sorting strategy for the dilation of the spherical grids. The construction and updating of the spherical Voronoi diagram are achieved through the ordered dilation of sites. Furthermore, the multi-scale visualization of the spherical Voronoi diagram is realized through the hierarchical structure of the QTM. The paper presents our algorithm intuitively through pseudocode, conducts comparative experiments on the feasibility and efficiency, and designs an experiment for the dynamic navigation and management of ocean-going vessels based on the global multi-resolution Voronoi diagram. The experimental results demonstrate that our algorithm effectively controls the error of the generation of the raster Voronoi diagram and has a significant efficiency advantage when processing dynamic environments.

To investigate the plasma lipoprotein subclasses in patients with primary open-angle glaucoma (POAG), a total of 20 Chinese POAG patients on intraocular pressure (IOP)-lowering treatment and 20 age-matched control subjects were recruited. Based on the levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C), the study subjects were divided into elevated- and normal-level subgroups. The plasma lipoprotein, lipoprotein subclasses, and oxidized LDL (oxLDL) levels were quantitatively measured. The discrimination potential of the lipoproteins was evaluated using the area under the receiver operating characteristic curve (AUC), and their correlation with clinical parameters was also evaluated. Compared to the control subjects with elevated TC and/or LDL-C levels, the levels of TC, LDL-C, non-high-density lipoprotein cholesterol (non-HDL), LDL subclass LDL3 and small dense LDL (sdLDL), and oxLDL were significantly higher in POAG patients with elevated TC and/or LDL-C levels. No differences in any lipoproteins or the subclasses were found between the POAG patients and control subjects with normal TC and LDL-C levels. Moderate-to-good performance of TC, LDL-C, non-HDL, LDL3, sdLDL, and oxLDL was found in discriminating between the POAG patients and control subjects with elevated TC and/or LDL-C levels (AUC: 0.710–0.950). Significant negative correlations between LDL3 and sdLDL with retinal nerve fiber layer (RNFL) thickness in the superior quadrant and between LDL3 and average RNFL thickness were observed in POAG patients with elevated TC and/or LDL-C levels. This study revealed a significant elevation of plasma lipoproteins, especially the LDL subclasses, in POAG patients with elevated TC and/or LDL-C levels, providing insights on monitoring specific lipoproteins in POAG patients with elevated TC and/or LDL-C.
