2Effects of Short-Term Forest Bathing on Human Health in a Broad-Leaved Evergreen Forest in Zhejiang Province,China显示文摘Objective To investigate the effects of short-term forest bathing on human health.Methods Twenty healthy male university students participated as subjects and were randomly divided into two groups of 10.One group was sent on a two-night trip to a broad-leaved evergreen forest,and the other was sent to a city area.Serum cytokine levels reflecting inflammatory and stress response,indicators reflecting oxidative stress,the distribution of leukocyte subsets,and plasma endothelin-1 (ET-1) concentrations were measured before and after the experiment to evaluate the positive health effects of forest environments.A profile of mood states (POMS) evaluation was used to assess changes in mood states.Results No significant differences in the baseline values of the indicators were observed between the two groups before the experiment.Subjects exposed to the forest environment showed reduced oxidative stress and pro-inflammatory level,as evidenced by decreased malondialdehyde,interleukin-6,and tumor necrosis factor α levels compared with the urban group.Serum cortisol levels were also lower than in the urban group.Notably,the concentration of plasma ET-1 was much lower in subjects exposed to the forest environment.The POMS evaluation showed that after exposure to the forest environment,subjects had lower scores in the negative subscales,and the score for vigor was increased.Conclusion Forest bathing is beneficial to human health,perhaps through preventive effects related to several pathological factors.MAO Gen Xiang LAN Xiao Guang CAO Yong Bao CHEN Zhuo Mei HE Zhi Huat LV Yuan Dong WANG Ya Zhen HU Xi Lian WANG Guo Fu YAN Jing 2012Biomedical and Environmental Sciences2012,25,3:20
3Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups.YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng 2016Biomedical and Environmental Sciences2016,29,3:18
4Microwave Exposure Impairs Synaptic Plasticity in the Rat Hippocampus and PC12 Cells through Over-activation of the NMDA Receptor Signaling Pathway显示文摘Objective The aim of this study is to investigate whether microwave exposure would affect the N-methyl-D-aspartate receptor(NMDAR) signaling pathway to establish whether this plays a role in synaptic plasticity impairment. Methods 48 male Wistar rats were exposed to 30 m W/cm2 microwave for 10 min every other day for three times. Hippocampal structure was observed through H&E staining and transmission electron microscope. PC12 cells were exposed to 30 m W/cm2 microwave for 5 min and the synapse morphology was visualized with scanning electron microscope and atomic force microscope. The release of amino acid neurotransmitters and calcium influx were detected. The expressions of several key NMDAR signaling molecules were evaluated. Results Microwave exposure caused injury in rat hippocampal structure and PC12 cells, especially the structure and quantity of synapses. The ratio of glutamic acid and gamma-aminobutyric acid neurotransmitters was increased and the intracellular calcium level was elevated in PC12 cells. A significant change in NMDAR subunits(NR1, NR2 A, and NR2B) and related signaling molecules(Ca2+/calmodulin-dependent kinase II gamma and phosphorylated c AMP-response element binding protein) were examined. Conclusion 30 m W/cm2 microwave exposure resulted in alterations of synaptic structure, amino acid neurotransmitter release and calcium influx. NMDAR signaling molecules were closely associated with impaired synaptic plasticity.XIONG Lu SUN Cheng Feng ZHANG Jing GAO Ya Bing WANG Li Feng ZUO Hong Yan WANG Shui Ming ZHOU Hong Mei XU Xin Ping DONG Ji YAO Bin Wei ZHAO Li PENG Rui Yun 2015Biomedical and Environmental Sciences2015,28,1:16

7Psychological status and diabetes-related distress of Chinese type 1 diabetes patients in Jiangsu province, China显示文摘We sought to assess the psychological status and diabetes-related distress of Chinese type 1 diabetes patients in Jiangsu province,China.According to the World Health Organization criteria,42 patients with type 1 diabetes were enrolled in the study and assessed with the Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS)and Diabetes Distress Scale(DDS).All data were tabulated and statistical analyses were performed.The study summarized cases of 42 patients with type 1 diabetes,including 17 males and 25 females with a mean age of 23±12 years and a mean duration of diabetes of 7±6 years.Compared to the Chinese normative data,the SAS standard score was significantly higher,whereas SDS standard score had no statistical significance.The SAS standard score was most highly correlated with diabetes duration(γ=0.547,P=0.011).Additionally,19.5%of the patients had moderate or even severe diabetes-related distress and 21.4%had moderate or even severe emotional burden while 26.2%had regimen-related distress.Multiple stepwise regression analysis showed that the mean correlation between DDS and the four domains was high,particularly the emotional burden domain(estimatedβ=0.363,P<0.001)and regimen-related distress domain(estimatedβ=0.356,P<0.001).The correlation between SAS and DDS was positive(estimatedβ=0.039,P=0.027).In conclusion,the results showed the importance of psychological aspects in Chinese individuals with type 1 diabetes.Screening and treatment of psychological aspects may result in better adherence and increased quality of life for patients with diabetes.Lulu Kong Yun Cai Gang Mei Rong Gu Xiaojiao Zhang Yao Qin Ya Cai Yan Li Hongwen Zhou Mei Zhang Tao Yang 2013The Journal of Biomedical Research2013,27,5:9
8Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8
9Association of Dietary Carotenoids Intake with Skeletal Fluorosis in the Coal-burning Fluorosis Area of Guizhou Province显示文摘Objective To explore whether the intake of dietary carotenoids could protect against skeletal fluorosis in Guizhou province in which coal-burning fluorosis is endemic. Methods A case-control study of 196 patients with skeletal fluorosis and 196 age and gender-matched controls was conducted in Zhijin, Guizhou Province. Face-to-face interviews were conducted to assess habitual dietary intake using a 75-item food frequency questionnaire and various covariates with structured questionnaires. Urinary fluoride was measured using an ion-selective electrode method. The genotype of superoxide dismutase 2(SOD2) rs11968525 was detected by Taq Man method. Results We observed significant dose-dependent inverse associations of skeletal fluorosis with intake of β-carotene, lutein/zeaxanthin, lycopene, and total carotenoids(P-trend = 0.002 to 0.018), whereas α-carotene and β-cryptoxanthin intakes were not found to be related to skeletal fluorosis, after adjustment for potential confounders. The adjusted ORs and 95% CI of skeletal fluorosis for the highest versus lowest quartile were 0.30(0.10, 0.86) for β-carotene, 0.23(0.08, 0.66) for lycopene, 0.26(0.10, 0.75) for lutein/zeaxanthin and 0.34(0.14, 0.74) for total carotenoids(all P-trend < 0.05). Stratified analyses showed that the protective effects of lutein/zeaxanthin and total carotenoids on skeletal fluorosis were more evident for individuals with the AG+AA genotypes of SOD2(rs11968525). Conclusion Increased intakes of β-carotene, lutein/zeaxanthin, lycopene, and total carotenoids are independently associated with a lower risk of coal-burning skeletal fluorosis. SOD2(rs11968525) polymorphisms might modify the inverse associations between dietary carotenoids and skeletal fluorosis.LIU Jun YANG Sheng LUO Ming Jiang ZHAO Xun ZHANG Yuan Mei LUO Ya 2018Biomedical and Environmental Sciences2018,31,6:7

14Altered Expression of Matrix Metalloproteinases and Tight Junction Proteins in Rats following PEMF-Induced BBB Permeability Change显示文摘Objective To investigate the expression of occludin,ZO‐1,MMP‐2,and MMP‐9 in cerebral microvasculature following Pulse Electromagnetic Field(PEMF) induced BBB permeability change.Methods Sprague‐Dawley rats were randomized into PEMF and sham exposed groups(n=8).After exposure to PEMF at 0.5,1,3,6,and 12 h,BBB permeability was measured by Evans‐Blue extravasation.The expression of occludin,ZO‐1,MMP‐2,and MMP‐9 were detected by real‐time quantitative reverse transcriptase PCR and western blotting.MMP‐2 and MMP‐9 activity were detected by EnzChek gelatinase assay.Results Compared with the sham group,PEMF exposure led to increased permeability of the BBB to EB,which was prolonged after exposure.BBB permeability became progressively more severe,and recovered at 6 h.The gene and protein expression of occludin and ZO‐1 were significantly decreased,while MMP‐2 and MMP‐9 expression were significantly increased after exposure to PEMF.All levels of expression recovered 12 h following PEMF.Conclusion Changes to BBB permeability were related to the alteration expression of tight junction proteins and matrix metalloproteinase after exposure to PEMF.ZHANG Ya Mei ZHOU Yan QIU Lian Bo DING Gui Rong PANG Xiao Feng 2012Biomedical and Environmental Sciences2012,25,2:5
15Microwave-induced Apoptosis and Cytotoxicity of NK Cells through ERK1/2 Signaling显示文摘Objective To investigate microwave-induced morphological and functional injury of natural killer(NK) cells and uncover their mechanisms. Methods NK-92 cells were exposed to 10, 30, and 50 m W/cm^2 microwaves for 5 min. Ultrastructural changes, cellular apoptosis and cell cycle regulation were detected at 1 h and 24 h after exposure. Cytotoxic activity was assayed at 1 h after exposure, while perforin and NKG2 D expression were detected at 1 h, 6 h, and 12 h after exposure. To clarify the mechanisms, phosphorylated ERK(p-ERK) was detected at 1 h after exposure. Moreover, microwave-induced cellular apoptosis and cell cycle regulation were analyzed after blockade of ERK signaling by using U0126. Results Microwave-induced morphological and ultrastructural injury, dose-dependent apoptosis(P < 0.001) and cell cycle arrest(P < 0.001) were detected at 1 h after microwave exposure. Moreover, significant apoptosis was still detected at 24 h after 50 m W/cm^2 microwave exposure(P < 0.01). In the 30 m W/cm^2 microwave exposure model, microwaves impaired the cytotoxic activity of NK-92 cells at 1 h and down regulated perforin protein both at 1 h and 6 h after exposure(P < 0.05). Furthermore, p-ERK was down regulated at 1 h after exposure(P < 0.05), while ERK blockade significantly promoted microwave-induced apoptosis(P < 0.05) and downregulation of perforin(P < 0.01). Conclusion Microwave dose-dependently induced morphological and functional injury in NK-92 cells, possibly through ERK-mediated regulation of apoptosis and perforin expression.ZHAO Li LI Jing HAO Yan Hui GAO Ya Bing WANG Shui Ming ZHANG Jing DONG Ji ZHOU Hong Mei LIU Shu Chen PENG Rui Yun 2017Biomedical and Environmental Sciences2017,30,5:5

19Inhibiting Hv1 channel in peripheral sensory neurons attenuates chronic inflammatory pain and opioid side effects显示文摘Both opioids and nonsteroidal anti-inflammatory drugs(NSAIDS)produce deleterious side effects and fail to provide sustained relief in patients with chronic inflammatory pain.Peripheral neuroinflammation(PN)is critical for initiation and development of inflammatory pain.A better understanding of molecular mechanisms underlying PN would facilitate the discovery of new analgesic targets and the development of new therapeutics.Emerging evidence suggests that peripheral sensory neurons are not only responders to painful stimuli,but are also actively engaged in inflammation and immunity,whereas the intrinsic regulatory mechanism is poorly understood.Here we report the expression of proton-selective ion channel Hv1 in peripheral sensory neurons in rodents and humans,which was previously shown as selectively expressed in microglia in mammalian central nervous system.Neuronal Hv1 was up-regulated by PN or depolarizing stimulation,which in turn aggravates inflammation and nociception.Inhibiting neuronal Hv1 genetically or by a newly discovered selective inhibitor YHV98-4 reduced intracellular alkalization and ROS production in inflammatory pain,mitigated the imbalance in downstream SHP-1-pAKT signaling,and also diminished pro-inflammatory chemokine release to alleviate nociception and morphine-induced hyperalgesia and tolerance.Thus,our data reveal neuronal Hv1 as a novel target in analgesia strategy and managing opioids-related side effects.Qiansen Zhang Yimin Ren Yiqing Mo Peipei Guo Ping Liao Yuncheng Luo Jie Mu Zhuo Chen Yang Zhang Ya Li Linghui Yang Daqing Liao Jie Fu Juwen Shen Wei Huang Xuewen Xu Yanyan Guo Lianghe Mei Yunxia Zuo Jin Liu Huaiyu Yang Ruotian Jiang 2022Cell Research2022,32,5:3
