2Moxibustion regulates inflammatory mediators and colonic mucosal barrier in ulcerative colitis rats显示文摘AIM: To observe the efficacy and mechanism of grainsized moxibustion at different acupoints in a rat model of ulcerative colitis(UC). METHODS: Sprague-Dawley rats were randomly divided into control, UC model, grain-sized moxibustion at a single acupoint(CV 12), grain-sized moxibustion at two acupoints(CV 12 and CV 4), grain-sized moxibustion at three acupoints(CV 12, CV 4, and ST 36), and medication groups(n = 8/group). The UC model was established by enema of trinitrobenzene sulfonic acid. Direct moxibustion was used once a day for 7 d. Disease activity index(DAI) was evaluated before and after the treatment. Morphologic changes of intestinal tissue were observed under an optical microscope. The expression of tumor necrosis factor(TNF)-α and p38 mitogen-activated protein kinase(p38MAPK) in colonic tissue was detected using Western blot, and the levels of occludin and zonula occludens-1(ZO-1) m RNAs were detected using reverse transcription PCR. RESULTS: Compared with the control group, the intestinal mucosae were incomplete in the model group, glandular structures were irregular, and submucosae were edematous, hyperemic, and infiltrated with inflammatory cells. The DAI scores and expression ofTNF-α and p38 MAPK were increased significantly in the model group compared to controls(P s < 0.01), while the m RNA levels of occludin and ZO-1 were reduced significantly(P s < 0.01). Compared with the model group, colonic mucosa and the arrangement of glands were complete and regular in the treatment groups. DAI scores and the expression of TNF-α and p38 MAPK were reduced significantly in moxibustion groups compared to controls(P s < 0.01), while the m RNA levels of occludin and ZO-1 were increased significantly(P s < 0.01). The improvements in the above indices in the three acupoints group and the medication group were superior to those in the single and two acupoints groups(all P < 0.05). CONCLUSION: Reduction of TNF-α and p38 MAPK and increased expression of occludin and ZO-1 in colonic tissue represent a potential mechanism for improved intestinal mucosal tissue repair with grain-sized moxibustion.Tie-Ming Ma Na Xu Xian-De Ma Zeng-Hua Bai Xing Tao Hong-Chi Yan 2016World Journal of Gastroenterology2016,22,8:30

4Root microbiota shift in rice correlates with resident time in the field and developmental stage显示文摘Land plants in natural soil form intimate relationships with the diverse root bacterial microbiota. A growing body of evidence shows that these microbes are important for plant growth and health. Root microbiota composition has been widely studied in several model plants and crops; however, little is known about how root microbiota vary throughout the plant's life cycle under field conditions. We performed longitudinal dense sampling in field trials to track the time-series shift of the root microbiota from two representative rice cultivars in two separate locations in China. We found that the rice root microbiota varied dramatically during the vegetative stages and stabilized from the beginning of the reproductive stage, after which the root microbiota underwent relatively minor changes until rice ripening. Notably, both rice genotype and geographical location influenced the patterns of root microbiota shift that occurred during plant growth. The relative abundance of Deltaproteobacteria in roots significantly increased overtime throughout the entire life cycle of rice, while that of Betaproteobacteria, Firmicutes, and Gammaproteobacteria decreased. By a machine learning approach, we identified biomarker taxa and established a model to correlate root microbiota with rice resident time in the field(e.g., Nitrospira accumulated from 5 weeks/tillering in field-grown rice). Our work provides insights into the process of rice root microbiota establishment.Jingying Zhang Na Zhang Yong-Xin Liu Xiaoning Zhang Bin Hu Yuan Qin Haoran Xu Hui Wang Xiaoxuan Guo Jingmei Qian Wei Wang Pengfan Zhang Tao Jin Chengcai Chu Yang Bai 2018Science China(Life Sciences)2018,61,6:24
5Guidance for the clinical evaluation of traditional Chinese medicine-induced liver injury Issued by China Food and Drug Administration显示文摘1.

7Effect of Alkali Stress on Soluble Sugar, Antioxidant Enzymes and Yield of Oat显示文摘Alkali stress can cause severe crop damage and reduce production. However, physiological processes involved in alkali stress in oat seedlings are not well understood. In this study, physiological responses and yield of oat to alkali stress were studied using the alkali-tolerant oat genotype Vao-9 and the alkali-sensitive oat genotype Baiyan 5. The results were: (i) low concentrations of alkali stress (25 and 50 mmol L-1) significantly reduced the yield and grain weight while increased the oat grain number per spike. A negative correlation between yield and malondialdehyde (MDA) content at the jointing and grain filling stages and positive correlations between yield on one hand and superoxide dismutase (SOD), and peroxidase (POD) activities on the other at the jointing stage were observed. There was a positive correlation between MDA and soluble sugar at the grain filling stage; (ii) soluble sugar content was increased at the jointing and grain filling stages and decreased at the heading stage by alkali stress; (iii) alkali stress increased the SOD activity during the heading and grain filling stages, and increased the POD activity at the heading stage. As compared to the control, the increase of MDA contents in alkali-treated oat was observed, during the jointing, heading and grain filling stages; (iv) under alkali stress, the oat genotype Vao-9 showed higher antioxidant enzyme activity and lower soluble sugar contents during the heading stage, and lower MDA contents than those in the oat genotype Baiyan 5 under alkali stress. The result suggested that the high ROS scavenging capacity and soluble sugar levels might play roles in oat response to alkali stress.BAI Jian-hui LIU Jing-hui ZHANG Na YANG Jun-heng SA Ru-la WU Lan 2013Journal of Integrative Agriculture2013,12,8:12
8Pretreated quercetin protects gerbil hippocampal CA1 pyramidal neurons from transient cerebral ischemic injury by increasing the expression of antioxidant enzymes显示文摘Quercetin(QE; 3,5,7,3′,4′-pentahydroxyflavone), a well-known flavonoid, has been shown to prevent against neurodegenerative disorders and ischemic insults. However, few studies are reported regarding the neuroprotective mechanisms of QE after ischemic insults. Therefore, in this study, we investigated the effects of QE on ischemic injury and the expression of antioxidant enzymes in the hippocampal CA1 region of gerbils subjected to 5 minutes of transient cerebral ischemia. QE was pre-treated once daily for 15 days before ischemia. Pretreatment with QE protected hippocampal CA1 pyramidal neurons from ischemic injury, which was confirmed by neuronal nuclear antigen immunohistochemistry and Fluoro-Jade B histofluorescence staining. In addition, pretreatment with QE significantly increased the expression levels of endogenous antioxidant enzymes Cu/Zn superoxide dismutase, Mn superoxide dismutase, catalase and glutathione peroxidase in the hippocampal CA1 pyramidal neurons of animals with ischemic injury. These findings demonstrate that pretreated QE displayed strong neuroprotective effects against transient cerebral ischemia by increasing the expression of antioxidant enzymes.Bai Hui Chen Joon Ha Park Ji Hyeon Ahn Jeong Hwi Cho In Hye Kim Jae Chul Lee Moo-Ho Won Choong-Hyun Lee In Koo Hwang Jong-Dai Kim Il Jun Kang Jun Hwi Cho Bich Na Shin Yang Hee Kim Yun Lyul Lee Seung Min Park 2017Neural Regeneration Research2017,12,2:9
9Single-cell RNA sequencing reveals atlas of dairy goat testis cells显示文摘Single-cell RNA sequencing(scRNA-seq)is useful for exploring cell heterogeneity.For large animals,however,little is known regarding spermatogonial stem cell(SSC)selfrenewal regulation,especially in dairy goats.In this study,we described a high-resolution scRNA-seq atlas derived from a dairy goat.We identified six somatic cell and five spermatogenic cell subtypes.During spermatogenesis,genes with significantly changed expression were mainly enriched in the Notch,TGF-β,and Hippo signaling pathways as well as the signaling pathway involved in the regulation of stem cell pluripotency.We detected and screened specific candidate marker genes(TKTL1 and AES)for spermatogonia.Our study provides new insights into goat spermatogenesis and the development of testicular somatic cells.Xiu-Wei Yu Tong-Tong Li Xiao-Min Du Qiao-Yan Shen Meng-Fei Zhang Yu-Dong Wei Dong-Hui Yang Wen-Jing Xu Wen-Bo Chen Chun-Ling Bai Xue-Ling Li Guang-Peng Li Na Li Sha Peng Ming-Zhi Liao Jin-Lian Hua 2021Zoological Research2021,42,4:9
10Quantitative Analysis of Moisture Effect on Black Soil Reflectance显示文摘Several studies have demonstrated that soil reflectance decreases with increasing soil moisture content, or increases when the soil moisture reaches a certain content; however, there are few analyses on the quantitative relationship between soil reflectance and its moisture, especially in the case of black soils in northeast China. A new moisture adjusting method was developed to obtain soil reflectance with a smaller moisture interval to describe the quantitative relationship between soil reflectance and moisture. For the soil samples with moisture contents ranging from air-dry to saturated, the changes in soil reflectance with soil moisture can be depicted using a cubic equation. Both moisture threshold (MT) and moisture inflexion (MI) of soil reflectance can also be determined by the equation. When the moisture range was smaller than MT, soil reflectance can be simulated with a linear model. However, for samples with different soil organic matter (OM), the parameters of the linear model varied regularly with the OM content. Based on their relationship, the soil moisture can be estimated from soil reflectance in the black soil region.LIU Huan-Jun ZHANG Yuan-Zhi ZHANG Xin-Le ZHANG Bai SONG Kai-Shan WANG Zong-Ming TANG Na 2009Pedosphere2009,19,4:8

12Association 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
13The Huashan risk calculators performed better in prediction of prostate cancer in Chinese population: a training study followed by a validation study显示文摘前列腺癌症预防试用(PCPT ) 的表演冒险计算器和其它风险计算器因为在中国人口的前列腺癌症(PCa ) 预言糟糕被理解。我们执行了这研究基于中国人口造风险计算器(Huashan 风险计算器) 并且验证了前列腺特定的抗原(PSA ) 的性能, PCPT 风险计算器,和在一个确认队的 Huashan 风险计算器。我们从在一个训练的队从 2006 年 1 月经历了起始的前列腺活体检视到 2010 年 12 月的 1059 个人基于数据造了 Huashan 风险计算器。然后,我们从 2011 年 1 月在观察确认研究验证了 PSA, PCPT 风险计算器,和 Huashan 风险计算器的性能到 2014 年 12 月。所有必要临床的信息在活体检视前被收集。结果证明 Huashan 冒险 1 和 2 超过了的计算器为在全部训练的队和成层的人口预言 PCa 的 PCPT 风险计算器(与到 20.0 ng m 的从 2.0 ng ml −1 的 PSA ) 。在确认学习, Huashan 风险计算器 1 仍然在全部确认队超过了 PCPT 风险计算器(0.849 对 0.779 在在操作特征的接收装置下面的区域弯[AUC ] 并且成层的人口。当 Huashan 风险计算器被使用时,不必要的活体检视(约 30%) 的可观的减小也被观察。因此,我们相信 Huashan 风险计算器(特别 Huashan 风险计算器 1 ) 可能为在中国人口预言 PCa 增加了价值。然而,这些结果仍然在更大的人口需要进一步的评估。Yi-Shuo Wu Ning Zhang Sheng-Hua Liu Jian-Feng Xu Shi-Jun Tong Ye-Hua Cai Li-Min Zhang Pei-De Bai Meng-Bo HU Hao-Wen Jiang Rong Na Qiang Ding Ying-Hao Sun 2016Asian Journal of Andrology2016,18,6:7
14P2X7 receptor activation aggravates NADPH oxidase 2-induced oxidative stress after intracerebral hemorrhage显示文摘Oxidative stress is a crucial pathological process that contributes to secondary injury following intracerebral hemorrhage. P2X7 receptor(P2X7R), which is activated by the abnormal accumulation of extracellular ATP, plays an important role in the regulation of oxidative stress in the central nervous system, although the effects of activated P2X7R-associated oxidative stress after intracerebral hemorrhage remain unclear. Mouse models of intracerebral hemorrhage were established through the stereotactic injection of 0.075 U VII collagenase into the right basal ganglia. The results revealed that P2X7R expression peaked 24 hours after intracerebral hemorrhage, and P2X7R expressed primarily in neurons. The inhibition of P2X7R, using A438079(100 mg/kg, intraperitoneal), reduced nicotinamide adenine dinucleotide phosphate oxidase 2(NOX2) expression and malondialdehyde generation, increased superoxide dismutase and glutathione/oxidized glutathione levels, and alleviated neurological damage, brain edema, and apoptosis after intracellular hemorrhage. The P2X7R inhibitor A438079(100 mg/kg, intraperitoneal injection) inhibited the activation of extracellular signal-regulated kinase 1/2(ERK1/2) and nuclear factor kappa-B(NF-κB) after intracerebral hemorrhage. Blocking ERK1/2 activation, using the ERK1/2 inhibitor U0126(2 μg, intraventricular injection), reduced the level of NOX2-mediated oxidative stress induced by P2X7R activation after intracellular hemorrhage. Similarly, the inhibition of NF-κB, using the NF-κB inhibitor JSH-23(3.5 μg, intraventricular), reduced the level of NOX2-mediated oxidative stress induced by P2X7R activation. Finally, GSK2795039(100 mg/kg, intraperitoneal), a NOX2 antagonist, attenuated P2X7R-mediated oxidative stress, neurological damage, and brain edema after intracerebral hemorrhage. The results indicated that P2X7R activation aggravated NOX2-induced oxidative stress through the activation of the ERK1/2 and NF-κB pathways following intracerebral hemorrhage in mice. The present study was approved by the Ethics Committee of Huazhong University of Science and Technology, China(approval No. TJ-A20160805) on August 26, 2016.Hong Deng Ye Zhang Gai-Gai Li Hai-Han Yu Shuang Bai Guang-Yu Guo Wen-Liang Guo Yang Ma Jia-Hui Wang Na Liu Chao Pan Zhou-Ping Tang 2021Neural Regeneration Research2021,16,8:6

16Effects of Outdoor Temperature on Blood Pressure in a Prospective Cohort of Northwest China显示文摘Objective The relationship between outdoor temperature and blood pressure(BP) has been inconclusive. We analyzed data from a prospective cohort study in northwestern China to investigate the effect of outdoor temperature on BP and effect modification by season.Methods A total of 32,710 individuals who participated in both the baseline survey and the first follow-up in 2011–2015 were included in the study. A linear mixed-effect model and generalized additive mixed model(GAMM) were applied to estimate the association between outdoor temperature and BP after adjusting for confounding variables.Results The mean differences in systolic blood pressure(SBP) and diastolic blood pressure(DBP)between summer and winter were 3.5 mm Hg and 2.75 mm Hg, respectively. After adjusting for individual characteristics, meteorological factors and air pollutants, a significant increase in SBP and DBP was observed for lag 06 day and lag 04 day, a 0.28 mm Hg(95% CI: 0.27–0.30) per 1 °C decrease in average temperature for SBP and a 0.16 mm Hg(95% CI: 0.15–0.17) per 1 °C decrease in average temperature for DBP, respectively. The effects of the average temperature on both SBP and DBP were stronger in summer than in other seasons. The effects of the average temperature on BP were also greater if individuals were older, male, overweight or obese, a smoker or drinker, or had cardiovascular diseases(CVDs), hypertension, and diabetes.Conclusions This study demonstrated a significant negative association between outdoor temperature and BP in a high-altitude environment of northwest China. Moreover, BP showed a significant seasonal variation. The association between BP and temperature differed by season and individuals' demographic characteristics(age, gender, BMI), unhealthy behaviors(smoking and alcohol consumption), and chronic disease status(CVDs, hypertension, and diabetes).ZHENG Shan WANG Min Zhen CHENG Zhi Yuan KANG Feng NIE Yong Hong MI Xiu Ying LI Hai Yan JIN Lan ZHANG Ya Wei BAI Ya Na 2021Biomedical and Environmental Sciences2021,34,2:5
17Temperature effect on the structural strains of an ancient Tibetan building based on long-term monitoring data显示文摘Many studies have indicated that structural strain will be significantly influenced by temperature variations,and a good understanding of the effect of temperature on structural strain is essential.A structural health monitoring system has been installed in a typical Tibetan timber building to measure the structural strains and ambient temperature since 2012.This paper presents the correlation between temperature and strain data from the monitored structure.A method combining singular spectrum analysis and polynomial regression is proposed for modeling the temperature induced strains in the structure.Singular spectrum analysis is applied to smooth the temperature data,and the correlation between the resulting temperature time series and the measured strains is obtained by polynomial regression.Parameters of the singular spectrum analysis and the regression model are selected to have the least regression error.Results show that the proposed method has both good reproduction and prediction capabilities for temperature induced strains,and that the method is accurate and effective for eliminating the effect of temperature from the measured strain.A standardized Novelty Index based on the residual strain is also used for the condition assessment of the structure.Bai Xiaobin Yang Na Yang Qingshan 2018Earthquake Engineering and Engineering Vibration2018,17,3:5
18Dmrt1 regulates the immune response by repressing the TLR4 signaling pathway in goat male germline stem cells显示文摘Double sex and mab-3-related transcription factor 1(Dmrt1),which is expressed in goat male germline stem cells(mGSCs)and Sertoli cells,is one of the most conserved transcription factors involved in sex determination.In this study,we highlighted the role of Dmrt1 in balancing the innate immune response in goat mGSCs.Dmrt1 recruited promyelocytic leukemia zinc finger(Plzf),also known as zinc finger and BTB domain-containing protein 16(Zbtb16),to repress the Toll-like receptor 4(TLR4)-dependent inflammatory signaling pathway and nuclear factor(NF)-κB.Knockdown of Dmrt1 in seminiferous tubules resulted in widespread degeneration of germ and somatic cells,while the expression of proinflammatory factors were significantly enhanced.We also demonstrated that Dmrt1 stimulated proliferation of mGSCs,but repressed apoptosis caused by the immune response.Thus,Dmrt1 is sufficient to reduce inflammation in the testes,thereby establishing the stability of spermatogenesis and the testicular microenvironment.Yu-Dong Wei Xiao-Min Du Dong-Hui Yang Fang-Lin Ma Xiu-Wei Yu Meng-Fei Zhang Na Li Sha Peng Ming-Zhi Liao Guang-Peng Li Chun-Ling Bai Wei-Shuai Liu Jin-Lian Hua 2021Zoological Research2021,42,1:5
19Vitality and wound-age estimation in forensic pathology:review and future prospects显示文摘Determining the age of a wound is challenging in forensic pathology,but it can contribute to the reconstruction of crime scenes and lead to arrest of suspects.Forensic scholars have tended to focus on evaluating wound vitality and determining the time elapsed since the wound was sustained.Recent progress in forensic techniques,particularly high-throughput analyses,has enabled evaluation of materials at the cellular and molecular levels,as well as simultaneous assessment of multiple markers.This paper provides an update on wound-age estimation in forensic pathology,summarizes the recent literature,and considers useful additional informa-tion provided by each marker.Finally,the future prospects for estimating wound age in foren-sic practise are discussed with the hope of providing something useful for further study.Na Li Qiuxiang Du Rufeng Bai Junhong Sun 2020Forensic Sciences Research2020,5,1:5
