Evaluation of Health Hazard and Governance Performance of Air Pollution: A Case Study of Z City.

Based on the date of the main pollutant discharge and the change of pollutant concentration in Z city, this study performed the statistical analysis of the concentration data in excel. The data covers 3 years from 1 January 2015 to 31 December 2017. An exposure-response relationship model was used established to evaluate the health hazards caused by air pollution and the corresponding economic losses, further analyzing the relationship between air pollution, health hazards, and economic benefits.

Metabolomic Analysis Reveals Nutritional Diversity among Three Staple Crops and Three Fruits.

More than 2 billion people worldwide are under threat of nutritional deficiency. Thus, an in-depth comprehension of the nutritional composition of staple crops and popular fruits is essential for health. Herein, we performed LC-MS-based non-targeted and targeted metabolome analyses with crops (including wheat, rice, and corn) and fruits (including grape, banana, and mango).

The Clinical Value of the Combined Detection of Enhanced CT, MRI, CEA, and CA199 in the Diagnosis of Rectal Cancer.

Background: To explore the clinical value of enhanced computed tomography (enhanced CT), magnetic resonance imaging (MRI), carcinoembryonic antigen (CEA), and cancer antigen 199 (CA199) in the diagnosis of rectal cancer (RC).

Methods: A total of 156 patients with RC confirmed by postoperative pathology admitted to the Affiliated Yantai Yuhuangding Hospital of Qingdao University from March 2018 to November 2020 were included in the malignant group, and 52 patients with chronic proctitis in the benign control group. All patients underwent preoperative enhanced CT, MRI scans, and serum CEA and CA199 tests.

The Impact of Emotional Labor on User Stickiness in the Context of Livestreaming Service-Evidence From China.

Improving the user stickiness becomes increasingly valued, due to the severe user churn of livestreaming services. Previous studies pay much attention to the influencing factors of technology on user stickiness, ignoring the emotional factors. This study examined the impact of the emotional labor of network anchors (deep acting vs.

Cross-Species Comparison of Metabolomics to Decipher the Metabolic Diversity in Ten Fruits.

Fruits provide humans with multiple kinds of nutrients and protect humans against worldwide nutritional deficiency. Therefore, it is essential to understand the nutrient composition of various fruits in depth. In this study, we performed LC-MS-based non-targeted metabolomic analyses with ten kinds of fruit, including passion fruit, mango, starfruit, mangosteen, guava, mandarin orange, grape, apple, blueberry, and strawberry.

Classification of Obviously Asymmetric Palpebral Fissures and Correction Based on Double Eyelid Surgery of the Primary Type.

Bilateral palpebral fissures (PF) are rarely symmetrical. Palpebral plastic surgery is common in the Chinese population. This study aimed to assess the classification of obviously asymmetric palpebral fissures (OAPF).

Comparison of diagnostic value of multi-slice spiral CT and MRI for different pathological stages of prostate cancer.

Diagnostic value of magnetic resonance imaging (MRI) and multi-slice spiral CT (MSCT) for different pathological stages of prostate cancer was compared. A total of 112 patients with prostate cancer who underwent surgical pathology in The Affiliated Yantai Yuhuangding Hospital of Qingdao University from February 2014 to January 2016 were enrolled as prostate cancer group, and another 100 patients who received physical health examinations during the same period as the normal group. MSCT and MRI scanning were performed on patients in both groups to analyze their diagnostic value for stages A/B and C/D of prostate cancer.

Association between vegetables and fruits consumption and depressive symptoms in a middle-aged Chinese population: An observational study.

There is scarce evidence regarding the association between the consumption of vegetables and fruits and depressive symptoms in Chinese population. The purpose of this study was to ascertain the influence of vegetables and fruits consumption on depressive symptoms in a middle-aged Chinese population. This study comprised 1676 Chinese adults aged between 45 and 59 years, who participated in a Health Survey at the time of periodic checkup in the city of Linyi, Shandong Province, China.

Dietary patterns derived by factor analysis are associated with cognitive function among a middle-aged and elder Chinese population.

The aim of this study was to assess the association of empirically derived dietary patterns with cognitive function among a middle-aged and elder Chinese population. This study comprised 1676 Chinese adults ≥45 years of age, who participated in a Health Survey and completed semi-quantitative food frequency questionnaire (FFQ) and cognitive screening test in the city of Linyi.We performed factor analysis using the principal component analysis method to identify the major dietary patterns.

Evaluation of pulmonary vein anatomy using 256-slice computed tomography.

Background/aim: This study aimed to evaluate pulmonary vein (PV) anatomy using 256-slice computed tomography (CT), which may be necessary for electrophysiologists to know before radiofrequency catheter ablation (RFCA) therapy.Materials and methods: A total of 102 patients with paroxysmal and persistent atrial fibrillation underwent 256-slice cardiac CT angiography prior to catheter ablation. PV morphology, ostial diameter, ostial orientation, and distance from ostium to first bifurcation were evaluated using three-dimensional volume-rendering and multiplanar-reformatting technology.

An observational study on the relationship between serum uric acid and hypertension in a Northern Chinese population aged 45 to 59 years.

Little is known about the relationship serum uric acid (SUA) and hypertension in Chinese population. Therefore, the aim of this study was to determine the association between SUA and hypertension in a northern Chinese population. The participants were a group of 1730 Chinese adults aged 45 to 59 years in Shandong Province, who were recruited from the Linyi Nutrition and Health Survey (2015-2016).

[Effects of electroacupuncture on the expression of nestin in endogenous neural stem cell in hippocampus in rats with focal cerebral ischemia-reperfusion].

Objective: To explore the mechanism of electroacupuncture for treating focal cerebral ischemia-reperfusion injury.

Methods: Seventy-five Wistar rats were randomly divided into a control group, a model group and an electroacupuncture group, 25 cases in each group. The model of focal cerebral ischemia-reperfusion was established by inserting nylon thread into the internal carotid artery except the control group which was only separated of the carotid artery without occlusion.
