| 1 | Pneumoconiosis: current status and future prospects显示文摘Pneumoconiosis refers to a spectrum of pulmonary diseases caused by inhalation of mineral dust,usually as the result of certain occupations.The main pathological features include chronic pulmonary inflammation and progressive pulmonary fibrosis,which can eventually lead to death caused by respiratory and/or heart failure.Pneumoconiosis is widespread globally,seriously threatening global public health.Its high incidence and mortality lie in improper occupational protection,and in the lack of early diagnostic methods and effective treatments.This article reviews the epidemiology,safeguard procedures,diagnosis,and treatment of pneumoconiosis,and summarizes recent research advances and future research prospects. | Xian-Mei Qi Ya Luo Mei-Yue Song Ying Liu Ting Shu Ying Liu Jun-Ling Pang Jing Wang Chen Wang | 2021 | Chinese Medical Journal2021，，8： | 22 |
| 2 | Effects 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 | 2012 | Biomedical and Environmental Sciences2012，25，3： | 20 |
| 3 | Microwave 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 | 2015 | Biomedical and Environmental Sciences2015，28，1： | 16 |
| 4 | Evaluating the Nutritional Status of Oncology Patients and Its Association with Quality of Life显示文摘Objective The primary aim of the study was to compare two nutritional status evaluation tools: the Patient-Generated Subjective Global Assessment(PG-SGA) and Nutritional Risk Screening(NRS-2002). Using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30(EORTC QLQ-C30), the second aim was to provide constructive advice regarding the quality of life of patients with malignancy. Methods This study enrolled 312 oncology patients and assessed their nutritional status and quality of life using the PG-SGA, NRS-2002, and EORTC QLQ-C30. Results The data indicate that 6% of the cancer patients were well nourished. The SGA-A had a higher sensitivity(93.73%) but a poorer specificity(2.30%) than the NRS-2002(69.30% and 25.00%, respectively) after comparison with albumin. There was a low negative correlation and a high similarity between the PG-SGA and NRS-2002 for evaluating nutritional status, and there was a significant difference in the median PG-SGA scores for each of the SGA classifications(P < 0.001). The SGA-C group showed the highest PG-SGA scores and lowest body mass index. The majority of the target population received 2 points for each item in our 11-item questionnaire from the EORTC QLQ-C30. Conclusion The data indicate that the PG-SGA is more useful and suitable for evaluating nutritional status than the NRS-2002. Additionally, early nutrition monitoring can prevent malnutrition and improve the quality of life of cancer patients. | ZHANG Ya Hui XIE Fang Yi CHEN Ya Wen WANG Hai Xia TIAN Wen Xia SUN Wen Guang WU Jing | 2018 | Biomedical and Environmental Sciences2018，31，9： | 14 |
| 5 | Tetrandrine alleviates silicosis by inhibiting canonical and non-canonical NLRP3 inflammasome activation in lung macrophages显示文摘Silicosis caused by inhalation of silica particles leads to more than ten thousand new occupational exposure-related deaths yearly.Exacerbating this issue,there are currently few drugs reported to effectively treat silicosis.Tetrandrine is the only drug approved for silicosis treatment in China,and despite more than decades of use,its efficacy and mechanisms of action remain largely unknown.Here,in this study,we established silicosis mouse models to investigate the effectiveness of tetrandrine of early and late therapeutic administration.To this end,we used multiple cardiopulmonary function test,as well as markers for inflammation and fibrosis.Moreover,using single cell RNA sequencing and transcriptomics of lung tissue and quantitative microarray analysis of serum from silicosis and control mice,our results provide a novel description of the target pathways for tetrandrine.Specifically,we found that tetrandrine attenuated silicosis by inhibiting both the canonical and non-canonical NLRP3 inflammasome pathways in lung macrophages.Taken together,our work showed that tetrandrine yielded promising results against silicosis-associated inflammation and fibrosis and further lied the groundwork for understanding its molecular targets.Our results also facilitated the wider adoption and development of tetrandirne,potentially accelerating a globally accepted therapeutic strategy for silicosis. | Mei-yue Song Jia-xin Wang You-liang Sun Zhi-fa Han Yi-tian Zhou Ying Liu Tian-hui Fan Zhao-guo Li Xian-mei Qi Ya Luo Pei-ran Yang Bai-cun Li Xin-ri Zhang Jing Wang Chen Wang | 2022 | Acta Pharmacologica Sinica2022，43，5： | 12 |
| 6 | Reproductive management through integration of PGD and MPS-based noninvasive prenatal screening/diagnosis for a family with GJB2-associated hearing impairment显示文摘A couple with a proband child of GJB2(encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis(PGD), noninvasive prenatal testing(NIPT), and noninvasive prenatal diagnosis(NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2 c.235del C heterozygous embryo resulted in a singleton pregnancy. At the 13 th week of gestation, genomic DNA(g DNA) from the trio family and cell-free DNA(cf DNA) from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by invasive procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing impairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders. | XIONG WenPing WANG DaYong GAO Yuan GAO Ya WANG HongYang GUAN Jing LAN Lan YAN JunHao ZONG Liang YUAN Yuan DONG Wei HUANG SeXin WU KeLiang WANG YaoShen WANG ZhiLi PENG HongMei LU YanPing XIE LinYi ZHAO Cui WANG Li ZHANG QiuJing GAO Yun LI Na YANG Ju YIN ZiFang HAN Bing WANG Wei CHEN Zi-Jiang WANG QiuJu | 2015 | Science China(Life Sciences)2015，58，9： | 12 |

| 8 | Antidepressant-Like Action of Single Facial Injection of Botulinum Neurotoxin A is Associated with Augmented 5-HT Levels and BDNF/ERK/CREB Pathways in Mouse Brain显示文摘The present study was designed to examine the therapeutic effects of Botulinum neurotoxin A(BoNT/A)on depression-like behaviors in mice and to explore the potential mechanisms.These results revealed that a single facial injection of BoNT/A induced a rapid and prolonged improvement of depression-like behaviors in naive and space-restriction-stressed(SRS)mice,reflected by a decreased duration of immobility in behavioral despair tests.BoNT/A significantly increased the 5-hydroxytryptamine(5-HT)levels in several brain regions,including the hippocampus and hypothalamus,in SRS mice.BoNT/A increased the expression of the N-methyl-Daspartate receptor subunits NR1 and NR2 B in the hippocampus,which were significantly decreased in SRS mice.Furthermore,BoNT/A significantly increased the expression of brain-derived neurotrophic factor(BDNF)in the hippocampus,hypothalamus,prefrontal cortex,and amygdala,which were decreased in SRS mice.Finally,BoNT/A transiently increased the levels of phosphorylated extracellular signal-regulated kinase(p-ERK)and cAMPresponse element binding protein(p-CREB),which were suppressed in the hippocampus of SRS mice.Collectively,these results demonstrated that BoNT/A treatment has antidepressant-like activity in mice,and this is associated with increased 5-HT levels and the activation of BDNF/ERK/CREB pathways in the hippocampus,supporting further investigation of BoNT/A therapy in depression. | Yang Li Jing Liu Xu Liu Cun-Jin Su Qi-Lin Zhang Zhi-Hong Wang Lei-Fang Cao Xue-Yan Guo Ya Huang Weifeng Luo Tong Liu | 2019 | Neuroscience Bulletin2019，35，4： | 10 |

| 13 | Pyruvate is a prospective alkalizer to correct hypoxic lactic acidosis显示文摘Type A lactic acidosis resulted from hypoxic mitochondrial dysfunction is an independent predictor of mortality for critically ill patients. However, current therapeutic agents are still in shortage and can even be harmful. This paper reviewed data regarding lactic acidosis treatment and recommended that pyruvate might be a potential alkalizer to correct type A lactic acidosis in future clinical practice. Pyruvate is a key energy metabolic substrate and a pyruvate dehydrogenase(PDH) activator with several unique beneficial biological properties, including anti-oxidant and antiinflammatory effects and the ability to activate the hypoxia-inducible factor-1(HIF-1α)-erythropoietin(EPO) signal pathway. Pyruvate preserves glucose metabolism and cellular energetics better than bicarbonate, lactate, acetate and malate in the efficient correction of hypoxic lactic acidosis and shows few side effects. Therefore, application of pyruvate may be promising and safe as a novel therapeutic strategy in hypoxic lactic acidosis correction accompanied with multi-organ protection in critical care patients. | Ying Wang Ya Huang Jing Yang Fang-Qiang Zhou Lian Zhao Hong Zhou | 2018 | Military Medical Research2018，5，4： | 8 |
| 14 | Association 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 无 | 2020 | Biomedical and Environmental Sciences2020，33，12： | 8 |
| 15 | Behavioral Abnormality along with NMDAR-related CREB Suppression in Rat Hippocampus after Shortwave Exposure显示文摘Objective To estimate the detrimental effects of shortwave exposure on rat hippocampal structure and function and explore the underlying mechanisms. Methods One hundred Wistar rats were randomly divided into four groups(25 rats per group) and exposed to 27 MHz continuous shortwave at a power density of 5, 10, or 30 m W/cm^2 for 6 min once only or underwent sham exposure for the control. The spatial learning and memory, electroencephalogram(EEG), hippocampal structure and Nissl bodies were analysed. Furthermore, the expressions of N-methyl-D-aspartate receptor(NMDAR) subunits(NR1, NR2 A, and NR2 B), c AMP responsive element-binding protein(CREB) and phosphorylated CREB(p-CREB) in hippocampal tissue were analysed on 1, 7, and 14 days after exposure. Results The rats in the 10 and 30 m W/cm^2 groups had poor learning and memory, disrupted EEG oscillations, and injured hippocampal structures, including hippocampal neurons degeneration, mitochondria cavitation and blood capillaries swelling. The Nissl body content was also reduced in the exposure groups. Moreover, the hippocampal tissue in the 30 m W/cm^2 group had increased expressions of NR2 A and NR2 B and decreased levels of CREB and p-CREB. Conclusion Shortwave exposure(27 MHz, with an average power density of 10 and 30 m W/cm^2) impaired rats' spatial learning and memory and caused a series of dose-dependent pathophysiological changes. Moreover, NMDAR-related CREB pathway suppression might be involved in shortwave-induced structural and functional impairments in the rat hippocampus. | YU Chao BAI Yan Xin XU Xin Ping GAO Ya Bing HAO Yan Hui WANG Hui TAN Sheng Zhi LI Wen Chao ZHANG Jing YAO Bin Wei DONG Ji ZHAO Li PENG Rui Yun | 2019 | Biomedical and Environmental Sciences2019，32，3： | 7 |
| 16 | ZmWRKY104 positively regulates salt tolerance by modulating ZmSOD4 expression in maize显示文摘Salinity impairs plant growth, limiting agricultural development. It is desirable to identify genes responding to salt stress and their mechanism of action. We identified a function of the Zea mays WRKY transcription factor, Zm WRKY104, in salt stress response. Zm WRKY104 was localized in the nucleus and showed transcriptional activation activity. Phenotypic and physiological analysis showed that overexpression of Zm WRKY104 in maize increased the tolerance of maize to salt stress and alleviated salt-induced increases in O;accumulation, malondialdehyde(MDA) content, and percent of electrolyte leakage. Further investigation showed that Zm WRKY104 increased SOD activity by regulating Zm SOD4 expression. Yeast onehybrid, electrophoretic mobility shift test, and chromatin immunoprecipitation–quantitative PCR assay showed that Zm WRKY104 bound directly to the promoter of Zm SOD4 by recognizing the W-box motif in vivo and in vitro. Phenotypic, physiological, and biochemical analysis showed that Zm SOD4 increased salt tolerance by alleviating salt-induced increases in O;accumulation, MDA content, and percent of electrolyte leakage under salt stress. Taken together, our results indicate that Zm WRKY104 positively regulates Zm SOD4 expression to modulate salt-induced O;accumulation, MDA content, and percent of electrolyte leakage, thus affecting salt stress response in maize. | Jingwei Yan Jing Li Heping Zhang Ya Liu Aying Zhang | 2022 | The Crop Journal2022，10，2： | 7 |
| 17 | Gasdermin D-mediated hepatocyte pyroptosis expands inflammatory responses that aggravate acute liver failure by upregulating monocyte chemotactic protein 1/CC chemokine receptor-2 to recruit macrophages显示文摘BACKGROUND Massive hepatocyte death is the core event in acute liver failure(ALF).Gasdermin D(GSDMD)-mediated pyroptosis is a type of highly inflammatory cell death.However,the role of hepatocyte pyroptosis and its mechanisms of expanding inflammatory responses in ALF are unclear.AIM To investigate the role and mechanisms of GSDMD-mediated hepatocyte pyroptosis through in vitro and in vivo experiments.METHODS The expression of pyroptosis pathway-associated proteins in liver tissues from ALF patients and a hepatocyte injury model was examined by Western blot.GSDMD short hairpin RNA(shRNA)was used to investigate the effects of downregulation of GSDMD on monocyte chemotactic protein 1(MCP1)and its receptor CC chemokine receptor-2(CCR2)in vitro.For in vivo experiments,we used GSDMD knockout mice to investigate the role and mechanism of GSDMD in a D-galactose/lipopolysaccharide(D-Galn/LPS)-induced ALF mouse model.RESULTS The levels of pyroptosis pathway-associated proteins in liver tissue from ALF patients and a hepatocyte injury model increased significantly.The level of GSDMD-N protein increased most obviously(P<0.001).In vitro,downregulation of GSDMD by shRNA decreased the cell inhibition rate and the levels of MCP1/CCR2 proteins(P<0.01).In vivo,GSDMD knockout dramatically eliminated inflammatory damage in the liver and improved the survival of DGaln/LPS-induced ALF mice(P<0.001).Unlike the mechanism of immune cell pyroptosis that involves releasing interleukin(IL)-1βand IL-18,GSDMDmediated hepatocyte pyroptosis recruited macrophages via MCP1/CCR2 to aggravate hepatocyte death.However,this pathological process was inhibited after knocking down GSDMD.CONCLUSION GSDMD-mediated hepatocyte pyroptosis plays an important role in the pathogenesis of ALF,recruiting macrophages to release inflammatory mediators by upregulating MCP1/CCR2 and leading to expansion of the inflammatory responses.GSDMD knockout can reduce hepatocyte death and inflammatory responses,thus alleviating ALF. | Hong Li Xue-Ke Zhao Yi-Ju Cheng Quan Zhang Jun Wu Shuang Lu Wei Zhang Yang Liu Ming-Yu Zhou Ya Wang Jing Yang Ming-Liang Cheng | 2019 | World Journal of Gastroenterology2019，25，44： | 7 |
| 18 | Three-dimensional Culture of Human Airway Epithelium in Matrigel for Evaluation of Human Rhinovirus C and Bocavirus Infections显示文摘Objective Newly identified human rhinovirus C(HRV-C) and human bocavirus(HBoV) cannot propagate in vitro in traditional cell culture models; thus obtaining knowledge about these viruses and developing related vaccines are difficult. Therefore, it is necessary to develop a novel platform for the propagation of these types of viruses. Methods A platform for culturing human airway epithelia in a three-dimensional(3 D) pattern using Matrigel as scaffold was developed. The features of 3 D culture were identified by immunochemical staining and transmission electron microscopy. Nucleic acid levels of HRV-C and HBoV in 3 D cells at designated time points were quantitated by real-time polymerase chain reaction(PCR). Levels of cytokines, whose secretion was induced by the viruses, were measured by ELISA. Results Properties of bronchial-like tissues, such as the expression of biomarkers CK5, ZO-1, and PCK, and the development of cilium-like protuberances indicative of the human respiration tract, were observed in 3 D-cultured human airway epithelial(HAE) cultures, but not in monolayer-cultured cells. Nucleic acid levels of HRV-C and HBoV and levels of virus-induced cytokines were also measured using the 3 D culture system. Conclusion Our data provide a preliminary indication that the 3 D culture model of primary epithelia using a Matrigel scaffold in vitro can be used to propagate HRV-C and HBoV. | CHEN Ya Xiong XIE Guang Cheng PAN Dong DU Ya Rong PANG Li Li SONG Jing Dong DUAN Zhao Jun HU Bu Rong | 2018 | Biomedical and Environmental Sciences2018，31，2： | 6 |
