| 1 | Boundary-processing-technique in EMD method and Hilbert transform显示文摘By virtue of neural network, a series of signals is extended forward and backward, as a result, two additional maxima and two additional minima are obtained at both ends of the original data set, with which the EMD decomposition can be exactly achieved with cubic spline interpolation. Meanwhile, by using of neural network every IMF component can also be extended forward and backward, which effectively restrains the end effect, thus the veracious Hilbert spectra are achieved. Verifications of the sample signals and the actual surface elevation of sea waves show that the present extension method is relatively accurate. | DENG Yongjun, WANG Wei, QIAN Chengchun, WANG Zhong & DAI DejunNetwork Center, Ocean University of Qingdao.

| 3 | Risk factors for cervical lymph node metastasis in papillary thyroid microcarcinoma: a study of 1,587 patients显示文摘Objective: The purposes of this study were to identify risk factors for cervical lymph node metastasis and to examine the association between BRAF^(V600E) status and clinical features in papillary thyroid microcarcinoma(PTMC).Methods: A total of 1,587 patients with PTMC, treated in Tianjin Medical University Cancer Institute and Hospital from January2011 to March 2013, underwent retrospective analysis. We reviewed and analyzed factors including clinical results, pathology records, ultrasound results, and BRAF^(V600E) status.Results: Multivariate logistic regression analyses demonstrated that gender(male) [odds ratio(OR) = 1.845, P = 0.000], age(< 45 years)(OR = 1.606, P = 0.000), tumor size(> 6 mm)(OR = 2.137, P = 0.000), bilateralism(OR = 2.011, P = 0.000) and extrathyroidal extension(OR = 1.555, P = 0.001) served as independent predictors of central lymph node metastasis(CLNM).Moreover, CLNM(OR = 29.354, P = 0.000) served as an independent predictor of lateral lymph node metastasis(LLNM). Among patients with a solitary primary tumor, those with tumor location in the lower third of the thyroid lobe or the isthmus were more likely to experience CLNM(P < 0.05). Univariate analyses indicated that CLNM, LLNM, extrathyroidal extension, and multifocality were not significantly associated with BRAF^(V600E) mutation.Conclusions: The present study suggested that prophylactic neck dissection of the central compartment should be considered in patients with PTMC, particularly in men with tumor size greater than 6 mm, age less than 45 years, extrathyroidal extension, and tumor bilaterality. Among patients with PTMC, BRAF^(V600E) mutation is not significantly associated with prognostic factors. For a better understanding of surgical management of PTMC and the risk factors, we recommend multicenter research and long-term follow-up. | Xiangqian Zheng Chen Peng Ming Gao Jingtai Zhi Xiukun Hou Jingzhu Zhao Xi Wei Jiadong Chi Dapeng Li Biyun Qian | 2019 | Cancer Biology & Medicine2019,16,1: | 54 |
| 4 | Bacterial Community Structure and Diversity in a Black Soil as Affected by Long-Term Fertilization显示文摘Black soil(Mollisol) is one of the main soil types in northeastern China. Biolog and polymerase chain reactiondenaturing gradient gel electrophoresis(PCR-DGGE) methods were used to examine the infiuence of various fertilizer combinations on the structure and function of the bacterial community in a black soil collected from Harbin,Heilongjiang Province. Biolog results showed that substrate richness and catabolic diversity of the soil bacterial community were the greatest in the chemical fertilizer and chemical fertilizer+manure treatments. The metabolic ability of the bacterial community in the manure treatment was similar to the control. DGGE fingerprinting indicated similarity in the distribution of most 16S rDNA bands among all treatments,suggesting that microorganisms with those bands were stable and not infiuenced by fertilization. However,chemical fertilizer increased the diversity of soil bacterial community. Principal component analysis of Biolog and DGGE data revealed that the structure and function of the bacterial community were similar in the control and manure treatments,suggesting that the application of manure increased the soil microbial population,but had no effect on the bacterial community structure. Catabolic function was similar in the chemical fertilizer and chemical fertilizer+manure treatments,but the composition structure of the soil microbes differed between them. The use of chemical fertilizers could result in a decline in the catabolic activity of fast-growing or eutrophic bacteria. | WEI Dan YANG Qian ZHANG Jun-Zheng WANG Shuang CHEN Xue-Li ZHANG Xi-Lin LI Wei-Qun | 2008 | Pedosphere2008,18,5: | 45 |

| 6 | Probiotics in Helicobacter pylori eradication therapy: A systematic review and meta-analysis显示文摘AIM: To summarize the evidence from randomized controlled trials(RCTs) regarding the effect of probiotics by using a meta-analytic approach.METHODS: In July 2013, we searched PubM ed, EMBASE, Ovid, the Cochrane Library, and three Chinese databases(Chinese Biomedical Literature Database, Chinese Medical Current Content, and Chinese Scientific Journals database) to identify relevant RCTs.We included RCTs investigating the effect of a combination of probiotics and standard therapy(probiotics group) with standard therapy alone(control group).Risk ratios(RRs) were used to measure the effect of probiotics plus standard therapy on Helicobacter pylori(H.pylori) eradication rates, adverse events, and patient compliance using a random-effect model.RESULTS: We included data on 6997 participants from 45 RCTs, the overall eradication rates of the probiotic group and the control group were 82.31% and 72.08%, respectively.We noted that the use of probiotics plus standard therapy was associated with an increased eradication rate by per-protocol set analysis(RR = 1.11; 95%CI: 1.08-1.15; P < 0.001) or intention-totreat analysis(RR = 1.13; 95%CI: 1.10-1.16; P < 0.001).Furthermore, the incidence of adverse events was 21.44% in the probiotics group and 36.27% in the control group, and it was found that the probiotics plus standard therapy significantly reduced the risk of adverse events(RR = 0.59; 95%CI: 0.48-0.71; P < 0.001), which demonstrated a favorable effect of probiotics in reducing adverse events associated with H.pylori eradication therapy.The specific reduction in adverse events ranged from 30% to 59%, and this reduction was statistically significant.Finally, probiotics plus standard therapy had little or no effect on patient compliance(RR = 0.98; 95%CI: 0.68-1.39; P = 0.889).CONCLUSION: The use of probiotics plus standard therapy was associated with an increase in the H.pylori eradication rate, and a reduction in adverse events resulting from treatment in the general population.However, this therapy did not improve patient compliance. | Min-Min Zhang Wei Qian Ying-Yi Qin Jia He Yu-Hao Zhou | 2015 | World Journal of Gastroenterology2015,21,14: | 41 |
| 7 | Double contrast-enhanced two-dimensional and three-dimensional ultrasonography for evaluation of gastric lesions显示文摘AIM:To investigate the value of two-dimensional(2D) and three-dimensional(3D) double contrast-enhanced ultrasonography(DCUS) imaging for evaluation of gastric lesions.METHODS:2D and 3D DCUS imaging with both oral and intravenous administrations of contrast agents was used to assess gastroscopiclly-confirmed gastric lesions in 46 patients with benign and malignant diseases.Initially,liquid-based ultrasound contrast agent(Xinzhang) was given orally at dose of 500-600 mL for conventional ultrasound examination of the gastric lesions,and then a microbubble-based contrast agent(SonoVue) was injected intravenously at dose of 1.2-2.4 mL in bolus fashion to assess the perfusion pattern of the lesions using contrast imaging modes.The parameters derived from time-intensity curves including the arrival time(AT),time to peak(TTP),peak intensity(PI) and enhanced intensity(EI) were measured on the 2D DCUS imaging.3D DCUS of the lesions was acquired to demonstrate the value of this imaging mode.RESULTS:There were 22 cases with benign lesions including chronic gastritis(n = 5),gastric ulcer(n = 9),gastric polyps(n = 3),gastric stromal tumors(n = 5),and 24 cases with malignant lesions including gastric cancer(n = 20),gastric cardia carcinoma(n = 3) and post-operative recurrent gastric cancer(n = 1) in the study.The oral contrast-enhanced ultrasonography(CEUS) imaging of the stomach clearly demonstrated the anatomy of the stomach and morphologic features of gastric lesions.With optimal scanning window and imaging display under oral CEUS,intravenous CEUS clearly showed the perfusion of gastric lesions with various characteristic manifestations.Both 2D and 3D DCUS images clearly demonstrated normal gastric wall as a three-layer structure,from the inside out,hyperechoic mucosa,hypoechoic muscularis and hyperechoic serosa,respectively.There were statistical significant differences of AT(8.68 ± 2.06 vs 10.43 ± 2.75,P = 0.017),PI(34.64 ± 6.63 vs 29.58 ± 8.22,P = 0.023) and EI(29.72 ± 6.69 vs 22.66 ± 7.01,P = 0.001) between malignant lesions and normal gastric wall.However,no differences of AT,PI and EI between benign lesions and normal gastric wall tissue were found.3D DCUS could intuitively display morphological features and vascularities of the lesions with multiplanar and volume views.3D DCUS imaging provided comprehensive information complementary to 2D imaging.The crater or wellhead appearances and feeding vessels as well as distorted nourishing vasculature of gastric carcinoma were better seen with 3D imaging than 2D imaging.CONCLUSION:DCUS imaging can simultaneously display the anatomic and perfusion features of gastric lesions.3D DCUS can provide additional information to 2D DCUS for evaluation of gastric lesions. | Hong Shi Xiu-Hua Yu Xin-Zhang Guo Yuan Guo Hong Zhang Bin Qian Zhang-Rui Wei Li Li Xian-Chen Wang Zi-Xiang Kong | 2012 | World Journal of Gastroenterology2012,18,31: | 36 |
| 8 | Review of risk factors for human echinococcosis prevalence on the Qinghai-Tibet Plateau, China: a prospective for control options显示文摘Objective: Echinococcosis is a major parasitic zoonosis of public health importance in western China. In 2004, the Chinese Ministry of Health estimated that 380,000 people had the disease in the region. The Qinghai-Tibet Plateau is highly co-endemic with both alveolar echinococcosis (AE) and cystic echinococcosis (CE). In the past years, the Chinese government has been increasing the financial support to control the diseases in this region. Therefore, it is very important to identify the significant risk factors of the diseases by reviewing studies done in the region in the past decade to help policymakers design appropriate control strategies. Review: Selection criteria for which literature to review were firstly defined. Medline, CNKI (China National Knowledge Infrastructure), and Google Scholar were systematically searched for literature published between January 2000 and July 2011. Significant risk factors found by single factor and/or multiple factors analysis were listed, counted, and summarized. Literature was examined to check the comparability of the data;age and sex specific prevalence with same data structures were merged and used for further analysis. A variety of assumed social, economical, behavioral, and ecological risk factors were studied on the Plateau. Those most at risk were Tibetan herdsmen, the old and female in particular. By analyzing merged comparable data, it was found that females had a significant higher prevalence, and a positive linearity relationship existed between echinococcosis prevalence and increasing age. In terms of behavioral risk factors, playing with dogs was mostly correlated with CE and/or AE prevalence. In terms of hygiene, employing ground water as the drinking water source was significantly correlated with CE and AE prevalence. For definitive hosts, dog related factors were most frequently identified with prevalence of CE or/and AE;fox was a potential risk factor for AE prevalence only. Overgrazing and deforestation were significant for AE prevalence only. Conclusion: Tibetan herdsmen communities were at the highest risk of echinococcosis prevalence and should be the focus of echinococcosis control. Deworming both owned and stray dogs should be a major measure for controlling echinococcosis;treatment of wild definitive hosts should also be considered for AE endemic areas. Health education activities should be in concert with the local people's education backgrounds and languages in order to be able to improve behaviors. Further researches are needed to clarify the importance of wild hosts for AE/CE prevalence, the extent and range of the impacts of ecologic changes (overgrazing and deforestation) on the AE prevalence, and risk factors in Tibet. | Qian Wang Yan Huang Liang Huang Wenjie Yu Wei He Bo Zhong Wei Li Xiangman Zeng Dominique A Vuitton Patrick Giraudoux Philip S Craig Weiping Wu | 2014 | Infectious Diseases of Poverty2014,3,1: | 35 |
| 9 | Paleoproterozoic crustal evolution of the Hengshan-Wutai—Fuping region,North China Craton显示文摘An arguable point regarding the Neoarchean and Paleoproterozoic crustal evolution of the North China Craton(NCC)is whether the tectonic setting in the central belt during the mid-Paleoproterozoic(2.35-2.0 Ga)was dominated by an extensional regime or an oceanic subduction-arc regime.A review of the midPaleoproterozoic magmatism and sedimentation for the Hengshan-Wutai-Fuping region suggests that a back-arc extension regime was dominant in this region.This conclusion is consistent with the observation that the 2.35-2.0 Ga magmatism shows a typical bimodal distribution where the mafic rocks mostly have arc affinities and the acidic rocks mainly comprise highly-fractioned calc-alkaline to alkaline(or A-type)granites,and that this magmatism was coeval with development of extensional basins characteristic of transgressive sequences with volcanic interlayers such as in the Hutuo Group.Although the final amalgamation of the NCC was believed to occur at ~1.85 Ga,recent zircon U-Pb age dating for mica schist in the Wutai Group suggests a collisional event may have occurred at ~1.95 Ga.The metamorphic ages of ~1.85 Ga,obtained mostly from the high-grade rocks using the zircon U-Pb approach,most probably indicate uplifting and cooling of these high-grade terranes.This is because(i)phase modeling suggests that newly-grown zircon grains in highgrade rocks with a melt phase cannot date the age of peak pressure and temperature stages,but the age of melt crystallization in cooling stages;(ii)the metamorphic P-T paths with isobaric cooling under 6-7 kb for the Hengshan and Fuping granulites suggest their prolonged stay in the middle-lower crust;and(iii)the obtained metamorphic age data show a continuous distribution from 1.95 to 1.80 Ga.Thus,an alternative tectonic scenario for the Hengshan-Wutai-Fuping region involves:(i)formation of a proto-NCC at ~2.5 Ga;(ii)back-arc extension during 2.35-2.0 Ga resulting in bimodal magmatism and sedimentation in rifting basins on an Archean basement;(iii)a crustal thickening event in the extended region resulting in a kyanitetype metamorphism at ~1.95 Ga,and(iv) uplifting and cooling of the thickened crust from 1.93 to 1.80 Ga. | Chunjing Wei Jiahui Qian Xiwen Zhou | 2014 | Geoscience Frontiers2014,5,4: | 32 |
| 10 | Fringe pattern analysis using deep learning显示文摘In many optical metrology techniques,fringe pattern analysis is the central algorithm for recovering the underlying phase distribution from the recorded fringe patterns.Despite extensive research efforts for decades,how to extract the desired phase information,with the highest possible accuracy,from the minimum number of fringe patterns remains one of the most challenging open problems.Inspired by recent successes of deep learning techniques for computer vision and other applications,we demonstrate for the first time,to our knowledge,that the deep neural networks can be trained to perform fringe analysis,which substantially enhances the accuracy of phase demodulation from a single fringe pattern.The effectiveness of the proposed method is experimentally verified using carrier fringe patterns under the scenario of fringe projection profilometry.Experimental results demonstrate its superior performance,in terms of high accuracy and edge-preserving,over two representative single-frame techniques:Fourier transform profilometry and windowed Fourier transform profilometry. | Shijie Feng Qian Chen Guohua Gu Tianyang Tao Liang Zhang Yan Hu Wei Yin Chao Zuo | 2019 | Advanced Photonics2019,1,2: | 31 |
| 11 | Caspase-11/4 and gasdermin D-mediated pyroptosis contributes to podocyte injury in mouse diabetic nephropathy显示文摘Diabetic nephropathy(DN)is characterized by sterile inflammation with continuous injury and loss of renal inherent parenchyma cells.Podocyte is an essential early injury target in DN.The injury and loss of podocytes are closely associated with proteinuria,the early symptom of renal injury in DN.However,the exact mechanism for podocyte injury and death in DN remains ambiguous.In this study we investigated whether pyroptosis,a newly discovered cell death pathway was involved in DN.Diabetic mice were generated by high-fat diet/STZ injections.We showed that the expression levels of caspase-11 and cleavage of gasdermin D(GSDMD-N)in podocytes were significantly elevated,accompanied by reduced expression of podocyte makers nephrin and podocin,loss and fusion in podocyte foot processes,increased inflammatory cytokines NF-κB,IL-1β,and IL-18,macrophage infiltration,glomerular matrix expansion and increased urinary albumin to creatinine ratio(UACR).All these changes in diabetic mice were blunted by knockout of caspase-11 or GSDMD.Cultured human and mouse podocytes were treated with high glucose(30 mM),which significantly increased the expression levels of caspase-11 or caspase-4(the homolog of caspase-11 in human),GSDMD-N,NF-κB,IL-1β,and IL-18,and decreased the expression of nephrin and podocin.Either caspase-4 or GSDMD knockdown by siRNA significantly blunted these changes.In summary,our results demonstrate that caspase-11/4 and GSDMD-mediated pyroptosis is activated and involved in podocyte loss under hyperglycemia condition and the development of DN. | Qian Cheng Jing Pan Zhuan-li Zhou Fan Yin Hong-yan Xie Pan-pan Chen Jing-yao Li Pei-qing Zheng Li Zhou Wei Zhang Jun Liu Li-min Lu | 2021 | Acta Pharmacologica Sinica2021,42,6: | 33 |
| 12 | Study on prevention effect of Zishen Yutai pill combined with progesterone for threatened abortion in rats显示文摘Objective:To observe preventive and therapeutic effects and the mechanism of actions on Zishen Yutai pill combined with progesterone on threatened abortion in rats.Methods:After pregnancy,50 SPF female SD rats were selected and divided into control group,model group,progesterone group,Zishen Yutai pill group,and progesterone plus Zishen Yutai pill group(combination group),with 10 rats in each group.The rats of control group and abortion model group were lavaged with 2 mL/kg normal saline on pregnancy day 1 for continuous 10 days.Rats in Zishen Yutai pill group were given 1.575 g/kg/d of Zishen Yutai pill for intragastric administration for continuous 10 days.Rats in progesterone group were given intramuscular injection treatment of 0.1 mL/d progestin,continuous for 10 days.Rats in combination group were given injection therapy of aqueous solution of Zishen Yutai pill for continuous 10 days,and other treatments were the same as previous two groups.Abortion model were established then and live births,numbers of abortion and average rate of abortion were compared between the five groups.Peripheral blood was collected to detect the estradiol(E2) and progestational hormone(P),and obtain ratio of Th1/Th2 cytokines(IL-2,INF-γ,IL-4,IL-10).Results:Significant more live births of rats were found in the control group compared with other four groups(P<0.05).The numbers of live births of the rats in abortion model group were significantly less than that of progesterone group,Zishen Yutai pill group and joint group(P<0.05).The numbers of live births of rats in joint group were significant more than that of progesterone group and Zishen Yutai pill group.The serum E2 level of P of rats in the control group,progesterone group,Zishen Yutai pill group and joint group were significant higher than that of abortion model group(P<0.05).Serum levels of E2 and P of rats in the control group,progesterone group,Zishen Yutai pill group and joint group were not significant different(P>0.05) but these levels in the control group and Zishen Yutai pill group were significant lower than that of progesterone group and joint group(P<0.05).The maternal-fetal interface IL-4/IL-2,IL-10 / IL-2 of model group were balanced deviating to Th1,while the IL-4/IL-2,IL-10/IL-2 of progesterone group,Zishen Yutai pill group and joint group were balanced deviating to Th2,and joint group' deviation was better than progesterone group and Zishen Yutai pill group(P<0.05).Conclusions:Zishen Yutai pill combined with progesterone has a significant control effect for threatened abortion,which can obviously increase contents of maternal serums E2 and P,and regulate the Thl/Th2 balance with a remarkable effect. | Yi Zhang Wei Yan Pu-Feng Ge Yan Li Qian Ye | 2016 | Asian Pacific Journal of Tropical Medicine2016,9,6: | 32 |

| 15 | Manganese is critical for antitumor immune responses via cGAS-STING and improves the efficacy of clinical immunotherapy显示文摘CD8^+T cell-mediated cancer clearance is often suppressed by the interaction between inhibitory molecules like PD-1 and PD-L1,an interaction acts like brakes to prevent T cell overreaction under normal conditions but is exploited by tumor cells to escape the immune surveillance.Immune checkpoint inhibitors have revolutionized cancer therapeutics by removing such brakes.Unfortunately,only a minority of cancer patients respond to immunotherapies presumably due to inadequate immunity.Antitumor immunity depends on the activation of the cGAS-STING pathway,as STING-deficient mice fail to stimulate tumor-infiltrating dendritic cells(DCs)to activate CD8^+T cells.STING agonists also enhance natural killer(NK)cells to mediate the clearance of CD8^+T cell-resistant tumors.Therefore STING agonists have been intensively sought after.We previously discovered that manganese(Mn)is indispensable for the host defense against cytosolic dsDNA by activating cGAS-STING.Here we report that Mn is also essential in innate immune sensing of tumors and enhances adaptive immune responses against tumors.Mn-insufficient mice had significantly enhanced tumor growth and metastasis,with greatly reduced tumor-infiltrating CD8^+T cells.Mechanically,Mn^2+promoted DC and macrophage maturation and tumor-specific antigen presentation,augmented CD8^+T cell differentiation,activation and NK cell activation,and increased memory CD8^+T cells.Combining Mn^2+with immune checkpoint inhibition synergistically boosted antitumor efficacies and reduced the anti-PD-1 antibody dosage required in mice.Importantly,a completed phase 1 clinical trial with the combined regimen of Mn^2+and anti-PD-1 antibody showed promising efficacy,exhibiting type I IFN induction,manageable safety and revived responses to immunotherapy in most patients with advanced metastatic solid tumors.We propose that this combination strategy warrants further clinical translation. | Mengze Lv Meixia Chen Rui Zhang Wen Zhang Chenguang Wang Yan Zhang Xiaoming Wei Yukun Guan Jiejie Liu Kaichao Feng Miao Jing Xurui Wang Yun-Cai Liu Qian Mei Weidong Han Zhengfan Jiang | 2020 | Cell Research2020,30,11: | 27 |
| 16 | Rhizospheric microbial communities are driven by Panax ginseng at different growth stages and biocontrol bacteria alleviates replanting mortality显示文摘The cultivation of Panax plants is hindered by replanting problems, which may be caused by plantdriven changes in the soil microbial community. Inoculation with microbial antagonists may efficiently alleviate replanting issues. Through high-throughput sequencing, this study revealed that bacterial diversity decreased,whereas fungal diversity increased, in the rhizosphere soils of adult ginseng plants at the root growth stage under different ages. Few microbial community, such as Luteolibacter, Cytophagaceae, Luteibacter, Sphingomonas,Sphingomonadaceae, and Zygomycota, were observed; the relative abundance of microorganisms, namely,Brevundimonas, Enterobacteriaceae, Pandoraea, Cantharellales, Dendryphion, Fusarium, and Chytridiomycota,increased in the soils of adult ginseng plants compared with those in the soils of 2-year-old seedlings. Bacillus subtilis 50-1, a microbial antagonist against the pathogenic Fusarium oxysporum, was isolated through a dual culture technique. These bacteria acted with a biocontrol efficacy of 67.8%. The ginseng death rate and Fusarium abundance decreased by 63.3% and 46.1%, respectively, after inoculation with B. subtilis 50-1. Data revealed that microecological degradation could result from ginseng-driven changes in rhizospheric microbial communities;these changes are associated with the different ages and developmental stages of ginseng plants. Biocontrol using microbial antagonists alleviated the replanting problem. | Linlin Dong Jiang Xu Lianjuan Zhang Ruiyang Cheng Guangfei Wei He Su Juan Yang Jun Qian Ran Xu Shilin Chen | 2018 | Acta Pharmaceutica Sinica B2018,8,2: | 27 |
| 17 | A Rabbit Model of Hormone-induced Early Avascular Necrosis of the Femoral Head显示文摘Objective To establish an experimental model of early stage avascular necrosis of the femoral head(ANFH) caused by corticosteroid in adult rabbits and to observe the pathological changes with various imaging techniques.Methods ANFH was induced by a combination of hypersensitivity vasculitis caused by injection of horse serum and subsequent administration of a high dose of corticosteroid.The pathological changes were detected with digital radiography(DR),computed tomography(CT),magnetic resonance imaging(MRI),ink artery infusion angiography,hematoxylin-eosin staining,and immunohistochemistry.Results The imageological and pathological changes corresponded to the clinical characteristics of early stage ANFH.DR showed bilaterally increased bone density,an unclear epiphyseal line,and blurred texture of cancellous bone.CT showed spot-like low-density imaging of cancellous bone,thinner cortical bone,osteoporosis,and an unclear epiphyseal line.MRI showed bone marrow edema and spot-like high signals in T2-weighted imaging in cancellous bone.Ink artery infusion angiography showed fewer obstructed blood vessels in the femoral head.HE staining of pathological sections showed fewer trabeculae and thin bone,an increased proportion of empty osteocyte lacunae,decreased hematopoiesis,thrombosis,and fat cell hypertrophy.Immunohistochemistry showed attenuated expression of vascular endothelial growth factor in osteoblasts and chondrocytes,and on the inner membrane of blood vessels.Conclusion Experimental rabbit model of early stage ANFH caused by corticosteroid can be successfully established and provide the foundation for developing effective methods to treat early stage ANFH. | QIAN WEN LI MA YAN-PING CHEN LIN YANG WEI LUO AND XIAO-NING WANG | 2008 | Biomedical and Environmental Sciences2008,21,5: | 24 |
| 18 | Root 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 | 2018 | Science China(Life Sciences)2018,61,6: | 24 |
| 19 | Report on Childhood Obesity in China (9): Sugar-sweetened Beverages Consumption and Obesity显示文摘Objective To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design. | SHANG Xian Wen LIU Ai Ling ZHANG Qian HU Xiao Qi DU Song Ming MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin LI Ting Yu MA Guan Sheng | 2012 | Biomedical and Environmental Sciences2012,25,2: | 23 |
| 20 | Ten cities cross-sectional questionnaire survey of children asthma and other allergies in China显示文摘Asthma,rhinitis and eczema(allergic or non-allergic)have increased throughout the world during the last decades,especially among children.Changes in the indoor environment are suspected to be important causes.China has experienced a dramatic change in indoor environmental exposures during the past two decades.However,such changes and their associations with children’s asthma and other health aspects have not been thoroughly studied.China,Children,Homes,Health(CCHH),Phase I,was a cross-sectional questionnaire survey of 48219 children 1–8 years old in 10 Chinese cities during 2010–2012.The questionnaire includes the International Study of Asthma and Allergies in Childhood(ISAAC)core health questions and additional questions regarding housing,life habits and outdoor environment.In health analyses,children aged 3–6 years old were included.The prevalences of doctor diagnosed asthma varied from 1.7%to 9.8%(mean 6.8%),a large increase from 0.91%in 1999 and 1.50%in2000.The prevalence of wheeze,rhinitis and atopic eczema(last 12 months)varied from 13.9%to 23.7%,24.0%to 50.8%and4.8%to 15.8%,respectively.Taiyuan had the lowest prevalences of all illnesses and Shanghai the highest,except for wheezewhere the highest value was for Urumqi.We found(1)no obvious association between disease prevalences and ambient PM10concentrations and(2)higher prevalences of disease in humid climates with hot summers and cold winters,but with no centrally heated buildings.Associations between the diseases and economic status as indexed by Gross Domestic Product(GDP)requires further study. | ZHANG YinPing LI BaiZhan HUANG Chen YANG Xu QIAN Hua DENG QiHong ZHAO ZhuoHui LI AnGui ZHAO JiaNing ZHANG Xin QU Fang HU Yu YANG Qin WANG Juan ZHANG Ming WANG Fang ZHENG XiaoHong LU Chan LIU ZhiJian SUN YueXia MO JinHan ZHAO YiLi LIU Wei WANG TingTing NORBCK Dan BORNEHAG Carl-Gustaf SUNDELL Jan | 2013 | Chinese Science Bulletin2013,58,34: | 22 |
