Influencing Factors on Campus Sports Culture in University in China

The study focused on identifying influencing factors on campus sports culture in university province in China, including demographic profiles, assessments of factors affecting culture development, differences in assessments based on profiles, and the relationship between influencing factors and culture development status. Based on the findings, an Enhanced Campus Sports Culture Program can be developed to improve campus sports culture. The study employed a descriptive correlational research design and the respondents are the students in Suzhou University, West Anhui University, Hefei Normal University, Chuzhou University and Huangshan University.Data revealed significant interest in campus sports culture among female, late adolescent, and freshman students, with perceptions of school factors, teacher dynamics, and student engagement influencing its development consistently across demographic groups. A shared understanding exists regarding the current state of campus sports culture, covering aspects like resources, systems, behavior, and spirit. Analysis indicated a strong positive correlation between perceived influencing factors and the actual development status of campus sports culture, indicating a need for an Enhanced Campus Sports Culture Program to foster positivity. Data suggests implementing initiatives to involve a broader demographic in campus sports culture, fostering a supportive environment and promoting understanding of influencing factors. This involves collaboration among university administration, faculty, and student organizations. Investing in sports resources and systems, ensuring equity, and prioritizing identified factors are crucial, led by the administration and stakeholders. Establishing a task force to implement strategies and develop an Enhanced Campus Sports Culture Program will drive sustained improvement.

Emergency medicine education via the micro-course and flipped classroom-reform of medical education during the COVID-19 pandemic.

The "micro-course" and "flipped classroom" are emerging tools for medical education but little is known about their utility for emergency medicine teaching. The suitability of the micro-course combined with flipped classroom is investigated for delivery of an emergency medicine course in West Anhui Health Vocational College. Students from Class A and Class B of the Clinical Department of West Anhui Health Vocational College, Grade 2000, were assigned to experimental (micro-course plus flipped classroom, n = 102) and control (traditional, didactic teaching, n = 104) groups, respectively. The effectiveness of teaching was assessed by theoretical tests and questionnaires at the end of the course. Theory test results were significantly better for the experimental group than for controls (t = 3.122, P < .01). General satisfaction of students who had participated in the micro-course plus flipped classroom exceeded that of those who had received traditional teaching. Enthusiasm, efficiency, and learning facility was self-reported to be enhanced by students in the experimental group relative to controls. Use of the micro-course combined with flipped classroom successfully increased the outcome of emergency medicine teaching and may be considered as an approach to reform emergency medicine teaching in medical colleges and universities.

Research on the Analysis of Efficiency and Potential Prediction of Cross-border E-Commerce Trade of Agricultural Products in West Anhui Based on Improved DEVA Model

Abstract This paper uses an improved DEVA model and stochastic frontier gravity method to combine natural and inefficient influencing factors to measure the optimal trade potential using cross-border e-commerce trade volume so that the stochastic disturbance term obeys a semi-normal truncated distribution. The optimal export value in cross-border e-commerce is calculated based on the trade inefficiency term to derive the factors affecting agricultural trade. The results show that the development scale of cross-border e-commerce trade in agricultural products continues to expand, and the export trade volume in western Anhui Province increased by 940,000 yuan in 2018, and the trade efficiency value fluctuates between 0.11 and 0.20. Strengthening control and improving the cross-border logistics system can help promote the high-quality development of cross-border trade in agricultural products and promote the construction of rural revitalization.

Correlation between clinicopathological characteristics and the clinical prognosis of patients with gastroenteropancreatic neuroendocrine tumors.

Gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) are one of the most common types of NETs, accounting for 65-75% of all NETs. However, epidemiological characteristics of patients with GEP-NETs in China are still lacking. The present retrospective study aimed to investigate the local epidemiology of GEP-NETs and assess the prognostic factors in China. The data of 267 patients with GEP-NETs who were admitted to the First Affiliated Hospital of Bengbu Medical College (Bengbu, China) and the Affiliated Hospital of West Anhui Health Vocational College (Lu'an, China) were retrospectively reviewed. The clinical and pathological characteristics of the patients, as well as follow-up information, were collected, and the 5-year survival rate was calculated. Kaplan-Meier curves and log-rank analysis were used to analyze the prognostic factors. The stomach (100/267; 37.5%) was the most common site of GEP-NETs and the liver (25/39; 64.1%) was the most common metastatic site. A total of 166 (62.2%) and 219 (82.0%) patients had positive results for chromogranin A (CgA) and synaptophysin (Syn), respectively. The percentage of patients with tumor grade G1, G2 and G3 was 33.3, 21.0 and 45.7%, respectively. The 5-year overall survival rate was 79.7%, and the age, tumor site, distant metastasis and tumor grading upon diagnosis were all prognostic factors. In conclusion, the present case series investigated the epidemiology and prognostic factors of GEP-NETs in China. CgA and Syn could be used as diagnostic markers for NETs and the stomach was the most common primary tumor site. Lymph node metastasis, tumor site, distant metastasis and tumor grading were important prognostic factors.

Associations of typical antibiotic residues with elderly blood lipids and dyslipidemia in West Anhui, China

Growing evidence has indicated the association of clinical antibiotic use with abnormal blood lipid levels; however, no epidemiological study has examined the relationship of antibiotic exposure, probably derived from food chains, with blood lipid levels. This study investigated the relationships of urinary antibiotic levels with blood lipid levels and dyslipidemias in the older population. Baseline data of 960 participants from the Cohort of Elderly Health and Environment Controllable Factors were used in the present study. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was performed to detect antibiotic residues in the urine samples of the participants. Our findings revealed that each 1 μg/g increase in enrofloxacin and ciprofloxacin levels was associated with an increase of 0.084 (95 % confidence interval (CI): 0.030, 0.139) and 0.049 (95 % CI: 0.012, 0.086) in triglyceride levels, respectively. Enrofloxacin was associated with an increased risk of hypertriglyceridemia. Each 1 μg/g increase in the enrofloxacin level corresponded to an increase of 0.052 (95 % CI: 0.006, 0.098) in the low-density lipoprotein cholesterol level. Furthermore, florfenicol exposure increased the risks of both hyperbetalipoproteinemia and hypoalphalipoproteinemia. By contrast, each 1 μg/g increase in sulfaclozine and doxycycline levels was associated with a − 0.062 (95 % CI: −0.111, −0.020), and − 0.083 (95 % CI: −0.160, −0.007) decrease in total cholesterol levels, respectively. Sulfaclozine was closely related to a decreased risk of hypercholesterolemia. Stratification analysis revealed specific differences in the correlation between antibiotic exposure and lipid levels based on the waist circumference (WC) values of the participants. Except for sulfaclozine and doxycycline, other antibiotics exerted adverse effects on lipid levels and increased dyslipidemia prevalence. The older participants with higher WC values were vulnerable to antibiotic exposure. Therefore, an appropriate understanding of the epidemiological attributes of antibiotic residues is indispensable to prevent abdominal obesity in the older population.

Antibiotic exposure and potential risk of depression in the Chinese elderly: a biomonitoring-based population study.

To examine the associations between urinary antibiotics from various sources and depression in the elderly using the biomonitoring method. In the current study, we investigated 990 elderly individuals (≥ 60 years old) from a community-based elderly cohort in West Anhui, China. The participants were interviewed by the Geriatric Depression Scale and self-developed questionnaires. A total of 45 antibiotics belonging to nine categories were screened in urine samples by the developed liquid chromatography electrospray tandem mass spectrometry method. Creatinine-corrected concentrations of antibiotics in urines were used to assess their exposure. Logistic regression analysis was employed to test the relationships between exposure to antibiotics and depression. Compared to the control group, the multinomial logistic regression analyses showed the elderly exposed to higher concentrations of azithromycin (OR = 1.81, 95% CI: 1.09-3.00) and sulfaclozine (OR = 1.54, 95% CI: 1.05-2.28) had increased risks of depression, respectively. After categorizing the detected antibiotics, tetracyclines (OR = 1.48, 95% CI: 1.02-2.16) and veterinary antibiotics (VAs) (OR = 1.53, 95% CI: 1.06-2.20) were positively correlated with increased risks of depression. After stratified by sex, the VAs (OR = 2.04, 95% CI: 1.13-3.71) at higher concentrations were associated with elevated risks of depression in males, while the associations between depression and antibiotic exposures were observed in tetracyclines (OR = 1.74, 95% CI: 1.04-2.85) and all antibiotics (OR = 2.24, 95% CI: 1.01-2.94) at higher levels in females, respectively. Notably, after the stratification by age, the significant associations were mainly present in the subjects under the age of 70. Our findings reveal that azithromycin, sulfaclozine, tetracyclines, and the VAs were significantly associated with elevated risks of depression in the elderly. Importantly, sex- and age-specific differences were observed in the associations between antibiotic exposures and depression.

Experimental Study on the Microbial Community Structure of the Sediment of Pi River under the Different pH in Winter

In order to solve the poor self-purification ability of low temperature water in winter, the microbial community structure in the sediment of Pi River water (located in West Anhui) was investigated experimentally in this study. Firstly, the sediment was sampled in the lower reaches of Pi River and prepared with the different pH (5.0, 5.5, 7.0 and 8.5); secondly, the prepared samples were tested by the high-throughput sequencing technology and the tested results showed that more than 40% of the bacteria in the sediment samples had an average relative abundance of less than 1.5% and the bacterial community was relatively dispersed and diversified; the relative abundance of Acidobacteria was the lowest, while Proteobacteria and Bacteroidetes were the opposite; additionally, the abundances of Nitrosomonadaceae, Nitrospirae and Nitrosomonadales samples (pH = 5.5, 7.0 and 8.5) were all less than 5%, while the abundance in pH = 5.0 samples was less than 1%; the specific species of alkaline sample is 0, because acidity had a great influence on the structure of microbial community, especially nitrifying bacteria, furthermore, the optimal environment for bacterial growth in sediments had an acidity threshold. Accordingly, this paper will provide a reference for the poor self-purification of water at low temperature in winter.

Wavelet Analysis on Temperature and Precipitation Changes in Dabie Mountain of West Anhui

The wavelet analysis method is applied to analysis of multi-level time change characteristics of temperature and precipitation in Dabie Mountain based on the meteorological observation data of five stations in Dabie Mountain from 1960 to 2013. According to results, the temperature shows oscillation periods of 22 years and 10 years in Dabie Mountain, West Anhui. While the precipitation shows an oscillation period of26 years. The change relationships of temperature and precipitation are not the same based on different time scales. From the scale of 3 years, to 10 years and 20 years, the out-of phase becomes weaker. The tendency of consistence appears gradually.

Inter-annual and Inter-decadal Variation of Temperature during 1960-2013 in Dabie Mountain of West Anhui Province

The inter-annual and inter-decadal variation of temperature in Dabie Mountain of West Anhui Province is analyzed according to actually measured data of daily average temperature, maximum temperature and minimum temperature during 1960-2013 in five meteorological stations in Dabie Mountain. Results show: The quarterly and annual average temperature, average maximum temperature and average minimum temperature (except the average maximum temperature in summer) in Dabie Mountain of West Anhui Province are all in a rising tendency. The annual average temperature increases remarkably at an amplitude of 0.165°C/10 years. The increase amplitude of average minimum temperature is 1-2 times of the average maximum temperature, and the daily range shows obvious reduction. The annual extremely maximum temperature and extremely minimum temperature are both on the rise, and the amplitude of the latter is larger than that of the former. From 1960s, the average temperature, average maximum temperature and average minimum temperature turned rising in Dabie Mountain of West Anhui Province. The abnormally warm years are 1967, 1968, 206, 207, 1998 and 2013, while the abnormally cold years are 1967 and 1981.

Analysis on Extreme Temperature and Precipitation Event in Dabie Mountain in West Anhui during 1960-2013

This paper adopts the daily maximum temperature, minimum temperature and precipitation observation data in 1960∼2013 of each county weather station in West Anhui to analyze changes of temperature and precipitation extremes in that area with linear method. Research shows: The days with nighttime and daytime extreme low temperature are decreasing obviously at the speed of 3.104 days/10 years and 1.157days/10 years. The decrease amplitude of days with nighttime extreme low temperature is 2-4 times of that in daytime. The days with nighttime and daytime extreme high temperature are increased at the speed of 2.529 days/10 years and 0.638day/10 years. The former has passed significance test, but the latter has not. The daily range is reducing at the speed of -0.076°C/10 years. The one-day maximum precipitation is rising at the speed of 3.411mm/10years, and five-day maximum precipitation is decreasing at the speed of -1.558mm/10 years; the days with moderate rain are decreased -0.176days/10 years; maximum continuous precipitation days are decreased -0.065 day/10 years; maximum continuous non-precipitation days are decreased -0.079 day/10years. However, the significance test has not been passed. The precipitation frequency in that area becomes smaller.

Taking the Shucheng County of Dabie Mountain area in west Anhui province as an example, based on InVEST model and terrain gradient method, this study analyzes the spatial-temporal evolution of habitat quality and the interaction between landscape pattern and gradient effect. The results showed that: (1)In the past two decades, the habitat quality index of the study area was 0.6392 in 1995 and 0.6356 in 2015, respectively. The value of habitat quality showed decline trend from 1995 to 2015, but the degree of habitat degradation continued to rise from 0.0133 to 0.0142. Hot spot analysis showed that the cold spot areas with poor habitat quality were mainly located in the northeastern and its peripheral zone of the study area, which is mainly dominated by cities and towns, and the hot spot areas with high habitat quality were mainly located in the southwestern vegetation distribution region. (2)Habitat quality and habitat degradation distribution have significant topographic potential gradient effect. The distribution index of high habitat quality was consistent with that of forest land and became dominant along with the topographic gradient, while the distribution of low habitat quality was consistent with that of construction land and farmland and became dominant along the topographic gradient. (3)There was a significant correlation between habitat quality and landscape pattern indexes at overall region level and sub-region level, but the characteristics of correlation varied greatly among four levels. The evolution of habitat quality is greatly influenced by topography and landscape pattern. The results could have certain theoretical and practical value for habitat protection and functional regulation of ecosystem in west Anhui Dabie Mountain area, which is an important ecological function area in China. 参考文献 相似文献 引证文献

Antibiotic body burden of elderly Chinese population and health risk assessment: A human biomonitoring-based study

Recently, the widespread use of antibiotic has raised concerns about the potential health risks associated with their microbiological effect. In the present study, we investigated 990 elderly individuals (age ≥ 60 years) from the Cohort of Elderly Health and Environment Controllable Factors in West Anhui, China. A total of 45 representative antibiotics and two antibiotic metabolites were monitored in urine samples through liquid chromatography electrospray tandem mass spectrometry. The results revealed that 34 antibiotics were detected in 93.0% of all urine samples and the detection frequencies of each antibiotic varied between 0.2% and 35.5%. The overall detection frequencies of seven human antibiotics (HAs), 10 veterinary antibiotics (VAs), three antibiotics preferred as HAs (PHAs), and 14 preferred as VAs (PVAs) in urines were 27.4%, 62.9%, 30.9% and 72.7%, respectively. Notably, the samples with concentrations of six PVAs (sulfamethoxazole, trimethoprim, oxytetracycline, danofloxacin, norfloxacin and lincomycin) above 5000 ng/mL accounted for 1.7% of all urine samples. Additionally, in 62.7% of urine samples, the total antibiotic concentration was in the range of the limits of detection to 20.0 ng/mL. Furthermore, the elderly individuals with the sum of estimated daily intakes of VAs and PVAs more than 1 μg/kg/day accounted for 15.2% of all participants, and a health risk related to change in gut microbiota under antibiotic stimulation was expected in 6.7% of the elderly individuals. Especially, ciprofloxacin was the foremost contributor to the health risk, and its hazard quotient value was more than one in 3.5% of all subjects. Taken together, the elderly Chinese people were extensively exposed to VAs, and some elderly individuals may have a health risk associated with dysbiosis of the gut microbiota.

Adhering to a vegetarian diet may create a greater risk of depressive symptoms in the elderly male Chinese population

BackgroundA vegetarian diet may be a risk factor for depression, but this relationship was unclear in the elderly Chinese population. MethodsSelf-report data were gathered from 1051 elderly persons using the Cohort of Elderly Health and Environment Controllable Factors, which was created in West Anhui, China. The depressive symptoms were set as binary, ordinal, and continuous outcomes, respectively, whereas the dietary structures were computed as an ordinal variable and a dummy variable. Multiple logistic regression, ordinal regression, and linear regression were used to assess the relationship by adjusting the potential confounding variables with p-values of <0.1 in univariate analysis. ResultsThe elderly participants who had a vegetable-based diet had the highest GDS scores of 8.78 ± 6.894 (p = 0.001) and the highest rate of depression (32.9%, p = 0.003). After adjustment for the potential confounders, elderly men who had a vegetable-based diet had a higher rate of depression (OR[95%CI]: 1.62[1.07–2.46], 4.71[1.38–16.03]), more severe symptoms of depression (OR[95%CI]: 8.85[2.94–34.12]), and higher GDS scores (β[95%CI]: 1.46[0.70–2.22], 2.97[1.28–4.67]) than male participants who had a meat-based diet, but this was not the case in women. LimitationsAll data were self-reported. The study lacked quantitatively evaluated dietary intake. The duration of the current dietary structures and comorbidities were not reported. The cross-sectional study made the causal role uncertain. ConclusionsVegetarian diets may pose a greater risk of depressive symptoms among the elderly Chinese population, especially elderly men. Given the cross-sectional nature of this study, the causal role was uncertain. Further prospective studies, in particular among elderly women, are needed.

Searches for Dark Matter via Mono-W Production in Inert Doublet Model at the LHC**Supported by the National Natural Science Foundation of China under Grant Nos. 11205003, 11305001, 11575002, the Key Research Foundation of Education Ministry of Anhui Province of China under Grant Nos. KJ2017A032, KJ2016A749, KJ2013A260, and Natural Science Foundation of West Anhui University under Grant No. WXZR201614

The Inert Doublet Model (IDM) is one of the many beyond Standard Model scenarios with an extended scalar sector, which provide a suitable dark matter particle candidate. Dark matter associated visible particle production at high energy colliders provides a unique way to determine the microscopic properties of the dark matter particle. In this paper, we investigate that the mono-W + missing transverse energy production at the Large Hadron Collider (LHC), where W boson decay to a lepton and a neutrino. We perform the analysis for the signal of mono-W production in the IDM and the Standard Model (SM) backgrounds, and the optimized criteria employing suitable cuts are chosen in kinematic variables to maximize signal significance. We also investigate the discovery potential in several benchmark scenarios at the 14 TeV LHC. When the light Z2 odd scalar higgs of mass is about 65 GeV, charged Higgs is in the mass range from 120 GeV to 250 GeV, it provides the best possibility with a signal significance of about 3σ at an integrated luminosity of about 3000 fb−1.
