ObjectiveTo understand the prevalence and influencing factors of depression among older adults relocated for poverty alleviation in Shanxi province, and to provide a reference for mental health promotion in the population. MethodsA face-to-face survey was conducted among 1 882 elderly residents (≥ 60 years) recruited through stratified multistage random sampling in 24 poverty alleviation settlements in 8 counties of Shanxi province from June to August 2023. The 10-item Center for Epidemiologic Studies of Depression Short Form (CES-D-10), the Chinese version of the Mini-Mental State Examination (CMMSE), the Katz Index of Independence in Activities of Daily Living Scale (Katz ADL), the abbreviated version of the Lubben Social Network Scale (LSNS-6), and a self-designed questionnaire were used in the study. A multivariate unconditional logistic regression model was used to analyze the main factors influencing of depression among the participants. ResultsFor the 1 851 older adults finally included in the analysis, the mean CES-D-10 score was 11.75 ± 5.88, with 915 (49.4%) classified as having depressive symptoms. The results of multivariate unconditional logistic regression analysis showed that female gender (odds ratio [OR] = 1.631, 95% confidence interval [95%CI]: 1.296 – 2.051), chronic disease (OR = 1.952, 95%CI: 1.573 – 2.421), limited activities of daily living (OR = 1.801, 95%CI: 1.269 – 2.555), and low social network level (OR = 1.627, 95%CI: 1.333 – 1.987) were risk factors for depression among older adults relocated for poverty alleviation, whereas physical activity (OR = 0.773, 95%CI: 0.605 – 0.987) was a protective factor against depression. ConclusionThe prevalence of depression symptoms is high and is mainly influenced by gender, physical activity, chronic disease, activities of daily living, and social network level among older adults relocated for poverty alleviation in Shanxi province.

SPL transcription factors are widely involved in plant growth and development, stress response and so on. At present, there is no study on the STM (SPL with transmembrane motif) transcription factor in Dendrobium officinale. In order to explore the role of STM in the growth, development and stress response of D. officinale, four STM transcription factors were identified at the whole genome of D. officinale, and bioinformatics analysis of DoSTM gene family members were carried out. The expression of DoSTM in different tissue parts and different stress treatments were studied by reverse transcription PCR. The results were as follows: (1)DoSTM1-4 were hydrophilic proteins with SBP conserved domains and some hormone response sites. (2)Four DoSTM were expressed in root, stem and leaf, and the relative expression of DoSTM2 was the lowest in leaf; there was no significant differences in the relative expression level of DoSTM1/3/4. (3)The relative expression level of DoSTM1-4 changed significantly under low temperature, high temperature and drought stress, and the expression of DoSTM1/3/4 decreased most significantly. Therefore, it is speculated that DoSTM is related to hormone response, temperature change response and drought resistance in plants. These conclusions provide the reference for the further research on STM transcription factor of D. officinale.

To explore the ameliorative effect of Acanathopanax senticosus polysaccharides (ASPs) on depressive behavior and possible mechanism, Wistar rats were divided into normal control group, model control group, fluoxetine hydrochloride group (2.1 mg/kg) and low-dose and high-dose ASPs groups (60 and 120 mg/kg, n=10). The depression model was established by solitary confinement and chronic mild unknown stress stimulation for 28 d, and the rats were given intragastric administration on the first day of modeling. Depressive behaviors were evaluated by open box experiment, sugar water preference experiment and forced swimming experiment. Hematoxylin-eosin staining and Nissl staining were used to detect hippocampal histopathology, and the indexes changes of interleukin 1β (IL-1β), IL-6, tumor necrosis factor α (TNF-α), catalase (CAT), superoxide dismutase (SOD), malondialdehyde (MDA), phosphorylated phosphatidylinositol 3 kinases (p-PI3K), phosphorylated protein kinase B (p-Akt) and phosphorylated mammalian target of rapamycin (p-mTOR) in each group were compared. The results proved that compared with normal control group, the number of horizontal activities and sugar water preference of model control group were significantly decreased (P

Pansharpening aims to sharpen a low-resolution multi-channel multispectral(MS) image from a high-resolution single-channel panchromatic(PAN) image to obtain a high resolution multispectral(HRMS) image,which is an important task in remote sensing image processing.A feedback network based on perceptual loss is proposed.First,the detail information and the spectral information are extracted from the PAN image and the MS image respectively,and then they are combined to use the stacked up-and down-sampling layers and dense connections for information fusion.The feedback connection is used to enrich the low-level information with high-level information.Finally,the HRMS image is reconstructed.Compared with the traditional pansharpening algorithms,the proposed algorithm uses the PAN image and the HRMS image as the supervision of the network,and the output image contains richer spatial detail information by obtaining the perceptual loss of the PAN image and the network reconstructed HRMS image.The experimental results show that the proposed algorithm has better results than the widely used algorithms both in objective evaluation and visual perception.

Objective To understand the current situation of aluminum pollution in the main foods in Inner Mongolia and to evaluate the risk of dietary aluminum exposure of local residents. Methods The aluminum residues of foods containing aluminum additives in food safety risk monitoring in Inner Mongolia from 2010 to 2018 were analyzed. Combined with the food consumption data of residents in Inner Mongolia in 2012, the dietary aluminum intake and health risk was calculated and assessed by sex-age group. Results In this assessment, there were 1 083 common aluminum-containing foods samples with a detection rate of 69.44%(752/1 083). The average content of aluminum residue was 142.81 mg/kg, ranging from 0.30 mg/kg to 2 950.00 mg/kg. The average weekly intake of dietary aluminum for the whole population was 0.692 mg/kg BW which was lower than the tolerable weekly intake(PTWI, 2 mg/kg BW) formulated by the Joint Expert Committee on Food Additives(JECFA). The weekly intake of dietary aluminum for people with high food consumption was 4.868 mg/kg BW. It was 2.43 times that of PTWI. The average weekly dietary aluminum intake of people in different gender-age groups did not exceed PTWI, and the average intake decreased with the increase of age. Conclusion Aluminum containing additives in vermicelli and deep-fried dough sticks exceeded the standard seriously. Aluminum containing additives in puffed food and fermented flour products were used beyond the scope. High-consumption groups of all sex-age groups are at greater risk of aluminum exposure. Relevant departments need to strengthen the supervision of the abuse of aluminum-containing additives.

Surface modified nano-flake Cu powder was prepared by plasma assisted ball milling by adding stearic acid as a process agent and its tribological properties were tested. The results indicate that the Cu particle exhibiting an excellent superplasticity has severe plastic deformation induced by a synergistic effect of plasma high-rate heating and electroplasticity, and the 20nm-thick flake-like Cu particles are obtained after 5h milling time of plasma milling. These nano-flake Cu particles owning oleophobicity characteristics exhibit good dispersion in the 40CA marine lubricating oil due to that the surface of Cu nano-flake adsorbs and chemically bonds with some non-polar groups under the plasma assisted ball milling with stearic acid. The severe deformation of the nano-flake Cu particles displaying high activation are easily adsorbed and spread on the surface of the friction counterpart in the process of sliding, which promotes a better wear resistance for compound lubricant with nano-flake Cu addition. Under a high rotating speed and excessive load, the nano-flake Cu powder provides excellent friction-reducing and self-repairing characters and improves the anti-wear performance under an extreme pressure condition.

Objective: To investigate the expression of Wnt5b in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) tissues and its correlation with the clinicopathological parameters., Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemical staining were employed to measure Wnt5b mRNA and protein expressions in two groups of HBV-related HCC patients (100 cases in each) selected from a cohort of 289 cases with HBV-related HCC using simple random sampling method. The correlation of Wnt5b expression with the clinicopathological parameters and the prognosis of HCC patients was analyzed., Results: Wnt5b mRNA expression was significantly higher in HCC tissues than that of adjacent noncancerous tissues in 65.0% (65/100) of the cases, and the positivity rate of Wnt5b protein was significantly higher in HCC tissues than that of adjacent noncancerous tissues (58.0% vs 22.0%, P<0.05). Wnt5b expression was significantly correlated with the tumor size (P<0.05), tumor number (P<0.01, only at the protein level), tumor differentiation (P<0.01, only at the protein level), TNM stage (P<0.05), BCLC stage (P<0.05), metastasis (P<0.05) and recurrence (P<0.01). The patients with up-regulated Wnt5b mRNA and protein had a shorter relapse-free survival (P<0.01)., Conclusion: s Up-regulated Wnt5b might contribute to the progression of HBV-related HCC and predicts a poor prognosis.
