| 2 | Isolation and Characterization of an Algicidal Bacterium Indigenous to Lake Taihu with a Red Pigment able to Lyse Microcystis aeruginosa显示文摘Objective To isolate and characterize indigenous algicidal bacteria and their algae-lysing compounds active against Microcystis aeruginosa, strains TH1, TH2, and FACHB 905. Methods The bacteria were identified using the Biolog automated microbial identification system and 16S rDNA sequence analysis. The algae-lysing compounds were isolated and purified by silica gel column chromatography and reverse-phase high performance liquid chromatography. Their structures were confirmed by Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FT-IR) spectroscopy. Algae-lysing activity was observed using microscopy. Results The algae-lysing bacterium LTH-2 isolated from Lake Taihu was identified as Serratia marcescens. Strain LTH-2 secreted a red pigment identified as prodigiosin (C 20 H 25 N 3 O), which showed strong lytic activity with algal strains M. aeruginosa TH1, TH2, and FACHB 905 in a concentration-dependent manner. The 50% inhibitory concentration (IC 50 ) of prodigiosin with the algal strains was 4.8 (±0.4)×10 -2 μg/mL, 8.9 (±1.1)×10-2 μg/mL, and 1.7 (±0.1)×10 -1 μg/mL in 24 h, respectively. Conclusion The bacterium LTH-2 and its pigment had strong Microcystis-lysing activity probably related to damage of cell membranes. The bacterium LTH-2 and its red pigment are potentially useful for regulating blooms of harmful M. aeruginosa. | YANG Fei WEI Hai Yan LI Xiao Qin LI Yun Hui LI Xiao Bo YIN Li Hong PU Yue Pu | 2013 | Biomedical and Environmental Sciences2013，26，2： | 19 |
| 3 | Effect of human umbilical cord-derived mesenchymal stem cells on lung damage in severe COVID-19 patients:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Treatment of severe Coronavirus Disease 2019(COVID-19)is challenging.We performed a phase 2 trial to assess the efficacy andsafety of human umbilical cord-mesenchymal stem cells(UC-MScs)to treat severe coViD-19 patients with lung damage,based onour phase 1 data.In this randomized,double-blind,and placebo-controlled trial,we recruited 101 severe coVID-19 patients withlung damage.They were randomly assigned at a 2:1 ratio to receive either UC-MSCs(4×10^(7)cells per infusion)or placebo on day 0,3,and 6.The primary endpoint was an altered proportion of whole lung lesion volumes from baseline to day 28.Other imagingoutcomes,6-minute walk test(6-MWT),maximum vital capacity,diffusing capacity,and adverse events were recorded and analyzed.In all,100 COVID-19 patients were finally received either UC-MSCs in=65)or placebo(n=35).UC-MSCs administrationexerted numerical improvement in whole lung lesion volume from baseline to day 28 compared with the placebo(the mediandifference was-13.31%,95%Cl-29.14%,2.13%,P=0.08).UC-MSCs significanty reduced the proportions of solid componentlesion volume compared with the placebo(median difference:-15.45%;95%CI-30.82%,-0.39%;P=0.043).The 6-MWT showedan increased distance in patients treated with UC-MSCs(difference:27.00 m;95%CI 0.00,57.00;P=0.057).The incidence of adverseevents was similar in the two groups.These results suggest that UC-MSCs treatment is a safe and potentially effective therapeuticapproach for COVID-19 patients with lung damage.A phase 3 trial is required to evaluate effects on reducing mortality andpreventing long-term pulmonary disability. | Lei Shi Hai Huang Xuechun Lu Xiaoyan Yan Xiaojing Jiang Ruonan Xu Siyu Wang Chao Zhang Xin Yuan Zhe Xu Lei Huang Jun-Liang Fu Yuanyuan Li Yu Zhang Wei-Qi Yao Tianyi Liu Jinwen Song Liangliang Sun Fan Yang Xin Zhang Bo Zhang Ming Shi Fanping Meng Yanning Song Yongpei Yu Jiqiu Wen Qi Li Qing Mao Markus Maeurer Alimuddin Zumla Chen Yao Wei-Fen Xie Fu-Sheng Wang | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 13 |
| 4 | Programmed Death Ligand-1 on Microglia Regulates Th1 Differentiation via Nitric Oxide in Experimental Autoimmune Encephalomyelitis显示文摘Microglia are considered to be potential antigen-presenting cells and have the ability to present antigen under pathological conditions. Nevertheless, whether and how microglia are involved in immune regulation are largely unknown. Here, we investigated the suppressive activity of microglia during experimental autoimmune encephalomyelitis(EAE) induced by myelin oligodendrocyte glycoprotein, with the goal of understanding their role in regulating the T cell reaction. Using flow cytometric analysis, we found that microglia were characterized by increased cell number and up-regulated programmed death ligand-1(PD-L1) at the peak phase of EAE. Meanwhile,both the CD^(4+)T cells and microglia that infiltrated the central nervous system expressed higher levels of PD1, the receptor for PD-L1, accompanied by a decline of Th1 cells.In an ex vivo co-culture system, microglia from EAE mice inhibited the proliferation of antigen-specific CD^(4+)T cells and the differentiation of Th1 cells, and this was significantly inhibited by PD-L1 blockade. Further,microglia suppressed Th1 cells via nitric oxide(NO), the production of which was dependent on PD-L1. Thus, these data suggest a scenario in which microglia are involved in the regulation of EAE by suppressing Th1-cell differentiation via the PD-L1-NO pathway. | Jingxia Hu Hao He Zhengang Yang Guangming Zhu Li Kang Xiuli Jing Hai Lu Wengang Song Bo Bai Hua Tang | 2016 | Neuroscience Bulletin2016，32，1： | 9 |
| 5 | Relationship between Maternal PBMC HBV cccDNA and HBV Serological Markers and its Effect on HBV Intrauterine Transmission显示文摘Objective To investigate the relationship between maternal peripheral blood mononuclear cells (PBMC) hepatitis B virus(HBV) covalenty closed circular deoxyribonucleic acid(cccDNA) and other HBV serological markers and its effects on HBV intrauterine transmission. Methods We enrolled 290 newborns and their hepatitis B surface antigen(HBsAg) positive mothers. HBV cccDNA in PBMC and HBV DNA in serum were detected by a real‐time PCR‐TaqM an probe while HBV serological markers were detected with an electrochemiluminescence immunoassay. Results There was a positive correlation between the levels of PBMC HBV cccD NA and serum HBV DNA and HBeA g(r = 0.436 and 0.403, P < 0.001). The detection rate of pattern A [‘HBsA g(+), HBeA g(+), and anti‐HBc(+)’] was significantly higher in the PBMC HBV cccD NA positive group than in the control group(χ^2 = 48.48, P < 0.001). There was a significant association between HBV intrauterine transmission and PBMC HBV cccD NA(χ^2 = 9.28, P = 0.002). In the presence of serum HBV DNA, HBeA g, and PBMC HBV cccD NA, the risk of HBV intrauterine transmission was three times higher(OR = 3.69, 95% CI: 1.30‐10.42) than that observed in their absence. The risk of HBV intrauterine transmission was the greatest(OR = 5.89, 95% CI: 2.35‐14.72) when both PBMC HBV cccD NA and pattern A were present. A Bayesian network model showed that maternal PBMC HBV cccD NA was directly related to HBV intrauterine transmission. Conclusion PBMC HBV cccDNA may be a direct risk factor for HBV intrauterine transmission. Our study suggests that serological markers could be combined with PBMC‐related markers in prenatal testing. | WANG Dan Dan YI Lin Zhu WU Li Na YANG Zhi Qing HAO Hai Yun SHI Xiao Hong WANG Bo FENG Shu Ying FENG Yong Liang WANG Su Ping | 2019 | Biomedical and Environmental Sciences2019，32，5： | 8 |
| 6 | 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 |
| 7 | The absolute paleoposition of the North China Block during the Middle Ordovician显示文摘Present-day hot spots and Phanerozoic large igneous provinces(LIPs) and kimberlites mainly occur at the edges of the projections of Large Low Shear Wave Velocity Provinces(LLSVPs) on the earth's surface. If a plate contains accurately dated LIPs or kimberlites, it is possible to obtain the absolute paleoposition of the plate from the LIP/kimberlite and paleomagnetic data. The presence of Middle Ordovician kimberlites in the North China Block provides an opportunity to determine the absolute paleoposition of the block during the Middle Ordovician. In addition to paleobiogeographical information and the results of previous work on global plate reconstruction for the Ordovician Period, we selected published paleomagnetic data for the North China Block during the Middle Ordovician and determined the most reasonable absolute paleoposition of the North China Block during the Middle Ordovician: paleolatitude of approximately 16.6°S to 19.1°S and paleolongitude of approximately 10°W. The block was located between the Siberian Plate and Gondwana, close to the Siberian Plate. During the Cambrian and Ordovician periods, the North China Block may have moved toward the Siberian Plate and away from the Australian Plate. | WANG Hong Hao LI Jiang Hai ZHANG Hua Tian XU Li LI Wei Bo | 2016 | Science China Earth Sciences2016，59，3： | 6 |
| 8 | Effect of Soy Isoflavone Crude Extract Supplementation on High Fat Diet-induced Insulin Resistance in Ovariectomized Rats显示文摘Female Wister rats aged 8 weeks were randomly divided into sham operation group,ovariectomized(OVX)control group,and 2 OVX groups fed with soy isoflavone crude extract supplementation.The rats had free access to high fat diet and water for 9 weeks.No significant difference was found in body weight(BW),total abdominal fat,food intake and food utilization rate between OVX control group and 2 OVX groups.However,the fasting blood glucose and blood lipid levels were significantly higher in 2 OVX groups than in OVX control group(P<0.05).Intraperitoneal glucose tolerance test(IGTT)showed that the area under AUC was smaller in 2 OVX groups than in OVX control group(P<0.05).These findings showed that soy isoflavone crude extract supplementation can improve glucose tolerance and prevent high fat diet-induced insulin resistance in ovariectomized rats. | ZHANG Yun Bo LI Li Na ZHAO Xin Yu CHEN Wen Hua GUO Jing Jing FU Zheng Hai YANG Yang NA Xiao Lin | 2014 | Biomedical and Environmental Sciences2014，27，1： | 6 |
| 9 | Stem cell lineage in body layer specialization and vascular patterning of rice root and leaf显示文摘Since the first appearance of vascular plants during evolution, the plant body has become specialized for adaption to land conditions. Much of our knowledge of plant body specialization and the origins of tissues from stem cells have been obtained from studies on the dicot Arabidopsis thaliana. However, less is known about plant body specialization in monocots, another important branch of angiosperms. In this study, we analyzed stem cell lineage and differentiation during development of the root and leaf of the monocot model plant rice(Oryza sativa). Our results showed that three body layers of rice are established from stem cells accompanied by progressively reduced pluripotency. Layer 1(L1) is a single-cell layer of epidermis; L2 is the cortex/endodermis in the root and the mesophyll in the leaf; and L3 is the site of vascular initiation. At least two common steps in vascular development are shared between rice root and leaf. The preprocambium divides to form the procambium and root pericycle or leaf outer sheath. The procambium further differentiates into the xylem, phloem and circumambient cells. We found that the outer sheath of leaf vascular bundles originates not only from the preprocambium of L3,but also from the mesophyll precursor cells of L2. In addition, WUSCHEL-RELATED HOMEOBOX(WOX)genes are expressed in not only the stem cell niche but also metaxylem precursor in rice. This pattern differs from that of homologs in Arabidopsis, suggesting that WOX functions have been recruited in different stem cells in dicots and monocots. | Minhuan Zeng Bo Hu Jiqin Li Guifang Zhang Ying Ruan Hai Huang Hua Wang Lin Xu | 2016 | Science Bulletin2016，61，11： | 5 |
| 10 | Ocular Trauma in a Rural Population of North China:The Handan Eye Study显示文摘Objective To determine the prevalence of ocular trauma and the proportion of blindness and visual impairment due to trauma in a rural population in northern China. Methods The Handan Eye Study is a population-based cross-sectional study that surveyed 6830 Chinese people aged 30+ years from 13 randomly selected villages in Yongnian County, city of Handan, Hebei Province, in July, 2006. All participants underwent a standardized interview and extensive examinations. A structured questionnaire was used to collect information on ocular trauma. Results Of the 5837 participants who filled out the questionnaire, 124 subjects [2.1%; 95% confidence interval(CI), 1.8%-2.5%] reported a history of ocular trauma in either eye, including 19(0.3%) persons reporting trauma in both eyes. Men were more likely to have an eye injury than women [odds ratio(OR), 3.3; 2.2-4.9]. In multiple logistic regression models, ocular trauma was significantly more frequent among normotensive participants when compared with hypertensive participants(hypertensive vs. normotensive: OR, 0.6; 0.4-0.9) and among participants who had a history of falls(OR, 2.4; 1.2-4.8). The proportion of unilateral visual impairment and unilateral blindness due to trauma were 10.5%(13 subjects) and 21.0%(26 subjects), respectively. Conclusion Our study reports the prevalence of severe ocular trauma among adults in rural China, revealing a high proportion of blindness and visual impairment due to trauma. These findings suggest the need for educational strategies to increase eye health awareness in this rural population with focus on providing at least appropriate first aid care to reduce blindness due to trauma. | ZHOU Jun WANG Feng Hua LU Hai LIANG Yuan Bo WANG Ning Li the Handan Eye Study Group | 2015 | Biomedical and Environmental Sciences2015，28，7： | 4 |
| 11 | Characterization of Avian Influenza A(H7N9) Virus Prevalence in Humans and Poultry in Huai′an,China:Molecular Epidemiology,Phylogenetic,and Dynamics Analyses显示文摘Objective To trace the source of human H7N9 cases in Huai'an and elucidate the genetic characterization of Huai'an strains associated with both humans and birds in live poultry market.Methods An enhanced surveillance was implemented when the first human H7N9 case was confirmed in Huai'an.Clinical specimens,cloacal swabs,and fecal samples were collected and screened by real-time reverse transcription-polymerase chain reaction(RT-PCR) for H7N9 virus.The positive samples were subjected to further RT-PCR and genome sequencing.The phylodynamic patterns of H7N9 virus within and separated from Huai'an and evolutionary dynamics of the virus were analyzed.Results Six patients with H7N9 infection were previously exposed to live poultry market and presented symptoms such as fever(>38.0 °C) and headaches.Results of this study support the hypothesis that live poultry markets were the source of human H7N9 exposure.Phylogenetic analysis revealed that all novel H7N9 viruses,including Huai'an strains,could be classified into two distinct clades,A and B.Additionally,the diversified H7N9 virus circulated in live poultry markets in Huai'an.Interestingly,the common ancestors of the Huai'an H7N9 virus existed in January 2012.The mean nucleotide substitution rates for each gene segment of the H7N9 virus were(3.09-7.26)×10-3 substitutions/site per year(95% HPD:1.72×10-3 to 1.16×10-2).Conclusion Overall,the source of exposure of human H7N9 cases in Huai'an was live poultry market,and our study highlights the presence of divergent genetic lineage of H7N9 virus in both humans and poultry specimens in Huai'an. | YANG Peng Fei YAN Qing Li LIU Chun Cheng XING Ya Dong ZHANG Min Hui GAO Qiang YU Hao YAO Hai Bo HE Nan Jiang | 2016 | Biomedical and Environmental Sciences2016，29，10： | 3 |

| 13 | Distinctive Drug-resistant Mutation Profiles and Interpretations of HIV-1 Proviral DNA Revealed by Deep Sequencing in Reverse Transcriptase显示文摘Objective To investigate distinctive features in drug-resistant mutations(DRMs) and interpretations for reverse transcriptase inhibitors(RTIs) between proviral DNA and paired viral RNA in HIV-1-infected patients. Methods Forty-three HIV-1-infected individuals receiving first-line antiretroviral therapy were recruited to participate in a multicenter AIDS Cohort Study in Anhui and Henan Provinces in China in 2004. Drug resistance genotyping was performed by bulk sequencing and deep sequencing on the plasma and whole blood of 77 samples, respectively. Drug-resistance interpretation was compared between viral RNA and paired proviral DNA. Results Compared with bulk sequencing, deep sequencing could detect more DRMs and samples with DRMs in both viral RNA and proviral DNA. The mutations M184 I and M230 I were more prevalent in proviral DNA than in viral RNA(Fisher's exact test, P<0.05). Considering ‘majority resistant variants', 15 samples(19.48%) showed differences in drug resistance interpretation between viral RNA and proviral DNA, and 5 of these samples with different DRMs between proviral DNA and paired viral RNA showed a higher level of drug resistance to the first-line drugs. Considering ‘minority resistant variants', 22 samples(28.57%) were associated with a higher level of drug resistance to the tested RTIs for proviral DNA when compared with paired viral RNA. Conclusion Compared with viral RNA, the distinctive information of DRMs and drug resistance interpretations for proviral DNA could be obtained by deep sequencing, which could provide more detailed and precise information for drug resistance monitoring and the rational design of optimal antiretroviral therapy regimens. | YIN Qian Qian LI Zhen Peng ZHAO Hai PAN Dong WANG Yan XU Wei Si XING Hui FENG Yi JIANG Shi Bo SHAO Yi Ming MA Li Ying | 2016 | Biomedical and Environmental Sciences2016，29，4： | 2 |

| 16 | Effects of Multiple Cleaning and Disinfection Interventions on Infectious Diseases in Children: A Group Randomized Trial in China显示文摘Objective To assess the effectiveness of multiple cleaning and disinfection interventions in the homes and kindergartens, in reducing gastrointestinal and respiratory illnesses of children. Methods From October 2010 to September 2011, we performed a prospective, controlled study in China. 408 children under 5 years old were recruited and group randomized into intervention and control groups. Families and kindergartens in the intervention group were provided with antibacterial products for hand hygiene and surface cleaning or disinfection for one year. Each child's illness symptoms and sick leave were recorded every day. Results A total of 393 children completed the study, with similar baseline demographics in each of the 2 groups. Except for abdominal pain, the odds of symptoms(fever, cough and expectoration, runny nose and nasal congestion, diarrhea), illness(acute respiratory illness and gastrointestinal illness), and sick leave per person each month were significantly reduced by interventions. The rates of fever, diarrhea, acute respiratory illness, gastrointestinal illness and sick leave per person per year were significantly decreased as well. Conclusion Not only the acute respiratory and gastrointestinal illness but the sick leave rate in children were significantly reduced by multiple interventions. | BAN Hai Qun LI Tao SHEN Jin LI Jin PENG Pin Zhang YE Heng Ping ZHANG Liu Bo | 2015 | Biomedical and Environmental Sciences2015，28，11： | 2 |
| 17 | Self-reported Taste and Smell Disorders in Patients with COVID-19:Distinct Features in China显示文摘Last December 2019,a cluster of viral pneumonia cases identified as coronavirus disease 2019(COVID-19)was reported in Wuhan,China.We aimed to explore the frequencies of nasal symptoms in patients with COVID-19,including loss of smell and taste,as well as their presentation as the first symptom of the disease and their association with the severity of COVID-19.In this retrospective study,1206 laboratory-confirmed COVID-19 patients were included and followed up by telephone one month after discharged from Tongji Hospital,Wuhan.Demographic data,laboratory values,comorbidities,symptoms,and numerical rating scale scores(0–10)of nasal symptoms were extracted from the hospital medical records,and confirmed or reevaluated by the telephone follow-up.From patients(n=1172)completing follow-up,199(17%)subjects had severe COVID-19 and 342(29.2%)reported nasal symptoms.20.6%COVID-19 patients had loss of taste(median score=6),while 11.4%had loss of smell(median score=5).Loss of taste scores,but not loss of smell scores,were significantly increased in severe vs.nonsevere COVID-19 patients.Interleukin(IL)-6 and lactose dehydrogenase(LDH)serum levels were positively correlated with loss of taste scores.About 80%of COVID-19 patients recovered from smell and taste dysfunction in 2 weeks.In this cohort,only 1 out of 10 hospital admitted patients had loss of smell while 1 out of 5 reported loss of taste which was associated to severity of COVID-19.Most patients recovered smell and taste dysfunctions in 2 weeks. | Jia SONG Yi-ke DENG Hai WANG Zhi-chao WANG Bo LIAO Jin MA Chao HE Li PAN Yang LIU Isam Alobid De-yun WANG Ming ZENG Joaquim Mullol Zheng LIU | 2021 | Current Medical Science2021，41，1： | 2 |
| 18 | The Screening of Genes Sensitive to Long-Term, Low-Level Microwave Exposure and Bioinformatic Analysis of Potential Correlations to Learning and Memory显示文摘Objective To gain a better understanding of gene expression changes in the brain following microwave exposure in mice. This study hopes to reveal mechanisms contributing to microwaveinduced learning and memory dysfunction. Methods Mice were exposed to whole body 2100 MHz microwaves with specific absorption rates(SARs) of 0.45 W/kg, 1.8 W/kg, and 3.6 W/kg for 1 hour daily for 8 weeks. Differentially expressing genes in the brains were screened using high-density oligonucleotide arrays, with genes showing more significant differences further confirmed by RT-PCR. Results The gene chip results demonstrated that 41 genes(0.45 W/kg group), 29 genes(1.8 W/kg group), and 219 genes(3.6 W/kg group) were differentially expressed. GO analysis revealed that these differentially expressed genes were primarily involved in metabolic processes, cellular metabolic processes, regulation of biological processes, macromolecular metabolic processes, biosynthetic processes, cellular protein metabolic processes, transport, developmental processes, cellular component organization, etc. KEGG pathway analysis showed that these genes are mainly involved in pathways related to ribosome, Alzheimer's disease, Parkinson's disease, long-term potentiation, Huntington's disease, and Neurotrophin signaling. Construction of a protein interaction network identified several important regulatory genes including synbindin(sbdn), Crystallin(Crya B), PPP1 CA, Ywhaq, Psap, Psmb1, Pcbp2, etc., which play important roles in the processes of learning and memory. Conclusion Long-term, low-level microwave exposure may inhibit learning and memory by affecting protein and energy metabolic processes and signaling pathways relating to neurological functions or diseases. | ZHAO Ya Li LI Ying Xian MA Hong Bo LI Dong LI Hai Liang JIANG Rui KAN Guang Han YANG Zhen Zhong HUANG Zeng Xin | 2015 | Biomedical and Environmental Sciences2015，28，8： | 2 |
