We present the observational results from a detailed timing analysis of the black hole candidate EXO 1846-031 during its outburst in 2019 with the observations of Insight-HXMT,NICER and *** outburst can be classified roughly into four different ***-C quasi-periodic oscillations(QPOs)observed by NICER(about 0.1-6 Hz)and Insight-HXMT(about 0.7-8 Hz)are also reported in this ***,we study various physical quantities related to QPO *** QPO rms-frequency relationship in the energy band 1-10 keV indicates that there is a turning pointing in frequency around2 Hz,which is similar to that of GRS 1915+105.A possible hypothesis for the relationship above may be related to the inclination of the source,which may require a high inclination to explain *** relationships between QPO frequency and QPO rms,hardness,total fractional rms and count rate have also been found in other transient sources,which can indicate that the origin of type-C QPOs is non-thermal.

目的监测2022年CHINET三级医院临床分离菌对抗菌药物的敏感性。方法国内58所三级医院临床分离菌采用纸片扩散法或商品化药敏试验自动测试仪按CHINET统一监测技术方案进行抗菌药物敏感性试验。结果按CLSI M1002022年版折点标准判断。结果收集2022年1月1日-12月31日上述医院临床分离菌共318013株,其中革兰阳性菌占29.5%,革兰阴性菌占70.5%。金黄色葡萄球菌、表皮葡萄球菌和其他凝固酶阴性葡萄球菌(除假中间葡萄球菌和施氏葡萄球菌外)中甲氧西林耐药株的检出率分别为28.3%、76.7%和77.9%。MRSA中有94.0%的菌株对甲氧苄啶-磺胺甲噁唑敏感;MRSE中有90.8%的菌株对利福平敏感,未发现万古霉素耐药株。肠球菌属中粪肠球菌对多数测试抗菌药物的耐药率均显著低于屎肠球菌,两者中均有少数万古霉素耐药株。2022年儿童和成人中分离的非脑膜炎肺炎链球菌中PSSP的检出率分别为94.2%和95.7%。除克雷伯菌属细菌对碳青霉烯类的耐药率范围为21.7%~23.1%外,其他细菌的耐药率多在13.1%以下。除天然耐药菌株外,其他肠杆菌目细菌对替加环素、黏菌素和多黏菌素B高度敏感,耐药率范围为0.1%~13.3%。铜绿假单胞菌对美罗培南的耐药率从2019年的23.5%下降至2022年的18.0%;鲍曼不动杆菌对美罗培南的耐药率亦从2019年的79.0%下降至2022年的72.5%。结论三级医院临床分离菌对常见抗菌药物的耐药率仍呈增长趋势,但碳青霉烯类耐药肺炎克雷伯菌、铜绿假单胞菌、鲍曼不动杆菌等多种重要耐药细菌的检出率近年来呈现连续下降趋势,提示加强细菌耐药监测,开展多学科联动的方式对控制耐药细菌的流行播散是行之有效的。
