Despite its significance, however, its prevalence in the Chinese general population remains unknown. This study aimed to investigate the prevalence of NONFH and its associated risk factors in the Chinese population. Methods: A nationally representative survey of 30,030 respondents was undertaken from June 2012 to August 2013. All participants underwent a questionnaire investigation, physical examination of hip, and bilateral hip joint X-ray and/or magnetic resonance imaging examination. Blood samples were taken after overnight fasting to test serum total cholesterol, triglyceride, and high-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels. We then used multivariate logistic regression analysis to investigate the associations between various metabolic, demographic, and lifestyle-related variables and NONFH. Results: NONFH was diagnosed in 218 subjects (0.725\%) and the estimated NONFH cases were 8.12 million among Chinese people aged 15 years and over. The prevalence of NONFH was significantly higher in males than in females (1.02\% vs. 0.51\%, \(\chi^2\) = 24.997, P < 0.001). Among NONFH patients, North residents were subjected to higher prevalence of NONFH than that of South residents (0.85\% vs. 0.61\%, \(\chi^2\) = 5.847, P = 0.016). Our multivariate regression analysis showed that high blood levels of triglycerides, total cholesterol, LDL-cholesterol, and non-HDL-cholesterol, male, urban residence, family history of osteonecrosis of the femoral head, heavy smoking, alcohol abuse and glucocorticoid intake, overweight, and obesity were all significantly associated with an increased risk of NONFH. Conclusions: Our findings highlight that NONFH is a significant public health challenge in China and underscore the need for policy measures on the national level. Furthermore, NONFH shares a number of risk factors with atherosclerosis.}, language = {en} } @article{XuHeKaiseretal.2016, author = {Xu, Li and He, Jianzheng and Kaiser, Andrea and Gr{\"a}ber, Nikolas and Schl{\"a}ger, Laura and Ritze, Yvonne and Scholz, Henrike}, title = {A Single Pair of Serotonergic Neurons Counteracts Serotonergic Inhibition of Ethanol Attraction in Drosophila}, series = {PLoS ONE}, volume = {11}, journal = {PLoS ONE}, number = {12}, doi = {10.1371/journal.pone.0167518}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-166762}, pages = {e0167518}, year = {2016}, abstract = {Attraction to ethanol is common in both flies and humans, but the neuromodulatory mechanisms underlying this innate attraction are not well understood. Here, we dissect the function of the key regulator of serotonin signaling—the serotonin transporter-in innate olfactory attraction to ethanol in Drosophila melanogaster. We generated a mutated version of the serotonin transporter that prolongs serotonin signaling in the synaptic cleft and is targeted via the Gal4 system to different sets of serotonergic neurons. We identified four serotonergic neurons that inhibit the olfactory attraction to ethanol and two additional neurons that counteract this inhibition by strengthening olfactory information. Our results reveal that compensation can occur on the circuit level and that serotonin has a bidirectional function in modulating the innate attraction to ethanol. Given the evolutionarily conserved nature of the serotonin transporter and serotonin, the bidirectional serotonergic mechanisms delineate a basic principle for how random behavior is switched into targeted approach behavior.}, language = {en} } @article{LiuChenGaoetal.2017, author = {Liu, Han and Chen, Chunhai and Gao, Zexia and Min, Jiumeng and Gu, Yongming and Jian, Jianbo and Jiang, Xiewu and Cai, Huimin and Ebersberger, Ingo and Xu, Meng and Zhang, Xinhui and Chen, Jianwei and Luo, Wei and Chen, Boxiang and Chen, Junhui and Liu, Hong and Li, Jiang and Lai, Ruifang and Bai, Mingzhou and Wei, Jin and Yi, Shaokui and Wang, Huanling and Cao, Xiaojuan and Zhou, Xiaoyun and Zhao, Yuhua and Wei, Kaijian and Yang, Ruibin and Liu, Bingnan and Zhao, Shancen and Fang, Xiaodong and Schartl, Manfred and Qian, Xueqiao and Wang, Weimin}, title = {The draft genome of blunt snout bream (Megalobrama amblycephala) reveals the development of intermuscular bone and adaptation to herbivorous diet}, series = {GigaScience}, volume = {6}, journal = {GigaScience}, number = {7}, doi = {10.1093/gigascience/gix039}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-170844}, year = {2017}, abstract = {The blunt snout bream Megalobrama amblycephala is the economically most important cyprinid fish species. As an herbivore, it can be grown by eco-friendly and resource-conserving aquaculture. However, the large number of intermuscular bones in the trunk musculature is adverse to fish meat processing and consumption. As a first towards optimizing this aquatic livestock, we present a 1.116-Gb draft genome of M. amblycephala, with 779.54 Mb anchored on 24 linkage groups. Integrating spatiotemporal transcriptome analyses, we show that intermuscular bone is formed in the more basal teleosts by intramembranous ossification and may be involved in muscle contractibility and coordinating cellular events. Comparative analysis revealed that olfactory receptor genes, especially of the beta type, underwent an extensive expansion in herbivorous cyprinids, whereas the gene for the umami receptor T1R1 was specifically lost in M. amblycephala. The composition of gut microflora, which contributes to the herbivorous adaptation of M. amblycephala, was found to be similar to that of other herbivores. As a valuable resource for the improvement of M. amblycephala livestock, the draft genome sequence offers new insights into the development of intermuscular bone and herbivorous adaptation.}, language = {en} } @article{WilsonAmblerLeeetal.2019, author = {Wilson, Duncan and Ambler, Gareth and Lee, Keon-Joo and Lim, Jae-Sung and Shiozawa, Masayuki and Koga, Masatoshi and Li, Linxin and Lovelock, Caroline and Chabriat, Hugues and Hennerici, Michael and Wong, Yuen Kwun and Mak, Henry Ka Fung and Prats-S{\´a}nchez, Luis and Mart{\´i}nez-Dome{\~n}o, Alejandro and Inamura, Shigeru and Yoshifuji, Kazuhisa and Arsava, Ethem Murat and Horstmann, Solveig and Purrucker, Jan and Lam, Bonnie Yin Ka and Wong, Adrian and Kim, Young Dae and Song, Tae-Jin and Schrooten, Maarten and Lemmens, Robin and Eppinger, Sebastian and Gattringer, Thomas and Uysal, Ender and Tanriverdi, Zeynep and Bornstein, Natan M and Ben Assayag, Einor and Hallevi, Hen and Tanaka, Jun and Hara, Hideo and Coutts, Shelagh B and Hert, Lisa and Polymeris, Alexandros and Seiffge, David J and Lyrer, Philippe and Algra, Ale and Kappelle, Jaap and Salman, Rustam Al-Shahi and J{\"a}ger, Hans R and Lip, Gregory Y H and Mattle, Heinrich P and Panos, Leonidas D and Mas, Jean-Louis and Legrand, Laurence and Karayiannis, Christopher and Phan, Thanh and Gunkel, Sarah and Christ, Nicolas and Abrigo, Jill and Leung, Thomas and Chu, Winnie and Chappell, Francesca and Makin, Stephen and Hayden, Derek and Williams, David J and Kooi, M Eline and van Dam-Nolen, Dianne H K and Barbato, Carmen and Browning, Simone and Wiegertjes, Kim and Tuladhar, Anil M and Maaijwee, Noortje and Guevarra, Christine and Yatawara, Chathuri and Mendyk, Anne-Marie and Delmaire, Christine and K{\"o}hler, Sebastian and van Oostenbrugge, Robert and Zhou, Ying and Xu, Chao and Hilal, Saima and Gyanwali, Bibek and Chen, Christopher and Lou, Min and Staals, Julie and Bordet, R{\´e}gis and Kandiah, Nagaendran and de Leeuw, Frank-Erik and Simister, Robert and van der Lugt, Aad and Kelly, Peter J and Wardlaw, Joanna M and Soo, Yannie and Fluri, Felix and Srikanth, Velandai and Calvet, David and Jung, Simon and Kwa, Vincent I H and Engelter, Stefan T and Peters, Nils and Smith, Eric E and Yakushiji, Yusuke and Necioglu Orken, Dilek and Fazekas, Franz and Thijs, Vincent and Heo, Ji Hoe and Mok, Vincent and Veltkamp, Roland and Ay, Hakan and Imaizumi, Toshio and Gomez-Anson, Beatriz and Lau, Kui Kai and Jouvent, Eric and Rothwell, Peter M and Toyoda, Kazunori and Bae, Hee-Yoon and Marti-Fabregas, Joan and Werring, David J}, title = {Cerebral microbleeds and stroke risk after ischaemic stroke or transient ischaemic attack: a pooled analysis of individual patient data from cohort studies}, series = {The Lancet Neurology}, volume = {18}, journal = {The Lancet Neurology}, organization = {Microbleeds International Collaborative Network}, doi = {10.1016/S1474-4422(19)30197-8}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-233710}, pages = {653-665}, year = {2019}, abstract = {Background Cerebral microbleeds are a neuroimaging biomarker of stroke risk. A crucial clinical question is whether cerebral microbleeds indicate patients with recent ischaemic stroke or transient ischaemic attack in whom the rate of future intracranial haemorrhage is likely to exceed that of recurrent ischaemic stroke when treated with antithrombotic drugs. We therefore aimed to establish whether a large burden of cerebral microbleeds or particular anatomical patterns of cerebral microbleeds can identify ischaemic stroke or transient ischaemic attack patients at higher absolute risk of intracranial haemorrhage than ischaemic stroke. Methods We did a pooled analysis of individual patient data from cohort studies in adults with recent ischaemic stroke or transient ischaemic attack. Cohorts were eligible for inclusion if they prospectively recruited adult participants with ischaemic stroke or transient ischaemic attack; included at least 50 participants; collected data on stroke events over at least 3 months follow-up; used an appropriate MRI sequence that is sensitive to magnetic susceptibility; and documented the number and anatomical distribution of cerebral microbleeds reliably using consensus criteria and validated scales. Our prespecified primary outcomes were a composite of any symptomatic intracranial haemorrhage or ischaemic stroke, symptomatic intracranial haemorrhage, and symptomatic ischaemic stroke. We registered this study with the PROSPERO international prospective register of systematic reviews, number CRD42016036602. Findings Between Jan 1, 1996, and Dec 1, 2018, we identified 344 studies. After exclusions for ineligibility or declined requests for inclusion, 20 322 patients from 38 cohorts (over 35 225 patient-years of follow-up; median 1·34 years [IQR 0·19-2·44]) were included in our analyses. The adjusted hazard ratio [aHR] comparing patients with cerebral microbleeds to those without was 1·35 (95\% CI 1·20-1·50) for the composite outcome of intracranial haemorrhage and ischaemic stroke; 2·45 (1·82-3·29) for intracranial haemorrhage and 1·23 (1·08-1·40) for ischaemic stroke. The aHR increased with increasing cerebral microbleed burden for intracranial haemorrhage but this effect was less marked for ischaemic stroke (for five or more cerebral microbleeds, aHR 4·55 [95\% CI 3·08-6·72] for intracranial haemorrhage vs 1·47 [1·19-1·80] for ischaemic stroke; for ten or more cerebral microbleeds, aHR 5·52 [3·36-9·05] vs 1·43 [1·07-1·91]; and for ≥20 cerebral microbleeds, aHR 8·61 [4·69-15·81] vs 1·86 [1·23-2·82]). However, irrespective of cerebral microbleed anatomical distribution or burden, the rate of ischaemic stroke exceeded that of intracranial haemorrhage (for ten or more cerebral microbleeds, 64 ischaemic strokes [95\% CI 48-84] per 1000 patient-years vs 27 intracranial haemorrhages [17-41] per 1000 patient-years; and for ≥20 cerebral microbleeds, 73 ischaemic strokes [46-108] per 1000 patient-years vs 39 intracranial haemorrhages [21-67] per 1000 patient-years). Interpretation In patients with recent ischaemic stroke or transient ischaemic attack, cerebral microbleeds are associated with a greater relative hazard (aHR) for subsequent intracranial haemorrhage than for ischaemic stroke, but the absolute risk of ischaemic stroke is higher than that of intracranial haemorrhage, regardless of cerebral microbleed presence, antomical distribution, or burden.}, language = {en} }
