The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

原发性免疫性血小板减少症(ITP)中少见但至关重要的危重出血事件,给患者的预后、生活质量和治疗决策带来严重影响。尽管有一些研究探讨了ITP中与危重出血相关的风险因素,但目前尚缺乏大样本数据、大规模多中心研究结果以及针对ITP患者致命出血事件的预测模型。本研究首次采用国际血栓与止血学会新提出的ITP致命出血标准,利用大样本数据开发了首个基于机器学习的在线应用,用于预测ITP患者的致命出血.研究中,我们使用中国各地大型多中心数据进行开发,并对全国39家医疗中心进行为期一年的外部测试,得到了较好的训练、验证和测试数据集预测能力该基于新算法的便捷网络工具能够快速识别ITP患者的出血风险,辅助临床决策,有望未来降低不良事件的发生。

目的监测我国主要城市三级甲等医院住院患者的细菌耐药状况,掌握耐药流行趋势,为抗生素合理使用提供科学数据。方法定点收集来自全国19家医院临床分离致病菌,由中心实验室统一用平皿/肉汤二倍稀释法测定抗菌药物最低抑菌浓度(MIC)值,参照美国临床和实验室标准协会(CLSI)或欧洲抗菌药物敏感性试验委员会(EUCAST) 2019年标准判定细菌敏感、耐药率。结果对来自全国19座城市19家三级甲等医院的4602株临床分离革兰氏阴性致病菌进行了MIC测定。结果显示,大肠埃希菌和肺炎克雷伯菌中超广谱β内酰胺酶(ESBLs)表型检出率分别为54. 6%和28. 1%,大肠埃希菌较前次下降约5个百分点,肺炎克雷伯菌持平。对肠杆菌科细菌抗菌作用较好的药物包括碳青霉烯类、阿米卡星、拉氧头孢、β内酰胺类合剂、替加环素、磷霉素氨丁三醇等,但碳青霉烯类耐药肺炎克雷伯菌比例继续增加。非发酵革兰氏阴性菌中铜绿假单胞菌和鲍曼不动杆菌对亚安培南的耐药率分别为29. 7%和71. 4%,多重耐药菌(MDR)检出率分别为31. 8%和75. 1%,泛耐药菌(XDR)检出率分别为9. 1%和69. 9%。不同病房、不同年龄以及不同标本来源菌株耐药率比较提示,儿童患者分离菌中肺炎克雷伯菌对β内酰胺类等药物耐药率显著高于成年人与老年人,我国儿童中细菌耐药问题不容忽视。结论大肠埃希菌ESBLs检出率有所下降;碳青霉烯类耐药肺炎克雷伯菌有继续增加趋势;多黏菌素E耐药肺炎克雷伯菌增加明显,值得注意。

目的监测我国主要城市三级甲等医院住院患者分离革兰氏阳性菌的耐药状况,掌握耐药流行趋势,为抗菌药物合理使用提供科学依据。方法定点收集来自全国19家医院的临床分离细菌,由中心实验室统一采用平皿/肉汤二倍稀释法测定抗菌药物的最低抑菌浓度(MIC)值。结果对2021年7月至2022年6月来自全国19座城市19家医院的1974株临床分离致病菌进行了MIC测定。结果显示,甲氧西林耐药金黄色葡萄球菌(MRSA)和甲氧西林耐药表皮葡萄球菌(MRSE)检出率分别为36.4%和79.9%。未发现万古霉素不敏感葡萄球菌,金黄色葡萄球菌对利奈唑胺、替考拉宁100%敏感。粪肠球菌、屎肠球菌对氨苄西林的耐药率分别为3.1%和92.9%。万古霉素耐药肠球菌(VRE)检出率为1.6%,利奈唑胺不敏感粪肠球菌比例为32.2%,连续2次监测上升;利奈唑胺不敏感屎肠球菌比例(12.5%)亦明显升高。青霉素不敏感肺炎链球菌(PNSSP)检出率按非脑膜炎、非肠道系统给药折点计算为0.8%,较前次监测下降近30个百分点,而按口服青霉素V折点计算为71.8%,较之前变化不大,提示青霉素MIC值较高(MIC≥4 mg·L^(-1))菌株数量显著减少。不同病房、不同年龄以及不同标本来源金黄色葡萄球菌、表皮葡萄球菌、粪肠球菌、屎肠球菌耐药率比较均无显著性差异。结论VRE检出率稳定在低水平;青霉素MIC值较高的肺炎链球菌较前次监测明显减少;利奈唑胺不敏感肠球菌明显增加,值得注意。

目的监测我国主要城市三级甲等医院住院患者分离革兰氏阴性菌耐药状况,掌握耐药流行趋势,为抗生素合理使用提供科学依据。方法定点收集来自全国19家医院的临床分离细菌,由中心实验室统一采用平皿/肉汤二倍稀释法测定抗菌药物的最低抑菌浓度(MIC)值。结果对2021年7月至2022年6月来自全国19座城市19家医院的4066株临床分离致病菌进行了MIC测定。结果显示,大肠埃希菌和肺炎克雷伯菌中超广谱β内酰胺酶(ESBLs)表型检出率分别为55.0%和21.0%,肺炎克雷伯菌ESBLs表型检出率继续下降,碳青霉烯类耐药肺炎克雷伯菌比例则较前次监测上升5个百分点。对肠杆菌目细菌抗菌作用较好的药物包括碳青霉烯类、拉氧头孢、西他沙星、β内酰胺合剂、磷霉素氨丁三醇、阿米卡星等,细菌敏感率在75%以上。此外,替加环素、奥玛环素、黏菌素和氟氧头孢对各自有效菌属/种保持很好的抗菌活性,细菌敏感率>80%。铜绿假单胞菌和鲍曼不动杆菌对亚安培南的耐药率分别为26.3%和72.1%,多重耐药菌(MDR)检出率分别为41.1%和77.3%,泛耐药菌(XDR)检出率分别为12.0%和71.8%。不同病房、不同年龄以及不同标本来源菌株耐药率比较提示,重症监护病房(ICU)分离肺炎克雷伯菌、鲍曼不动杆菌耐药率较非ICU分离菌显著升高,ICU分离肺炎克雷伯菌碳青霉烯类耐药率>35%;儿童分离流感嗜血杆菌对β内酰胺类、大环内酯类、克林霉素耐药率以及肺炎克雷伯菌中ESBLs检出率高于成人和老年人,儿童细菌耐药问题不容忽视。结论大肠埃希菌ESBLs检出率经多年持续下降后略有回升;碳青霉烯类耐药铜绿假单胞菌比例稳定,但肺炎克雷伯菌、鲍曼不动杆菌对碳青霉烯类耐药率仍有升高,值得注意。
