Novel polycarbonates from 5-allyloxy-1, 3-dioxan-2-one （ATMC） with 5, 5-dimethyl- 1, 3-dioxan-2-one （DTC） were successfully synthesized for the first time using immobilized porcine pancreas lipase （IPPL） as catalyst. The resulting copolymers were characterized by IR, ^1H NMR, ^13C NMR and GPC. The molecular weight （Mn） of the copolymer with molar feed ratio of 10：90 （ATMC：DTC） was 9300 and the polydispersity was 1.31, while the Mn increased to 14300 and polydispersity of 1.25 with the feed ratio of 50：50. Moreover, the composition of the copolymers agreed well with the monomer feed.

A new six-membered cyclic carbonate monomer, 5-allyloxytrimethylene carbonate （ATMC）, was synthesized starting from glycerol, and the corresponding polycarbonates, poly（5-allyloxytrimethylene carbonate）（PATMC） were further synthesized by ring-opening polymerization in bulk at 150℃ using stannous octanoate as an initiator. The structures of the monomer and the polymers were confirmed by IR, IH-NMR, 13C-NMR, and GPC analysis.

目的了解CHINET中国细菌耐药性监测网儿童患者临床分离的不发酵糖革兰阴性杆菌的分布和耐药性变迁。方法按CHINET耐药监测统一方案使用纸片扩散法或商品化药敏试验自动测试仪进行药敏试验。按CLSI 2021年版标准判断结果。结果临床分离不发酵糖革兰阴性杆菌26987株中,主要以假单胞菌属和不动杆菌属细菌为主,其他各菌属均有不等检出。下呼吸道标本占51.1%,居于首位,脓液及伤口分泌物占16.5%,尿液标本占9.2%。这些菌株主要分离于内科病房(38.1%)、儿科ICU(26.8%)和外科病房(18.9%)。铜绿假单胞菌对氨曲南耐药率最高,为22.7%,对碳青霉烯类抗生素耐药率为15.6%,对其他抗菌药物耐药率均低于10%。碳青霉烯类耐药鲍曼不动杆菌检出率54.1%,明显高于铜绿假单胞菌的15.6%,2020年和2021年出现下降趋势。碳青霉烯类耐药铜绿假单胞菌在新生儿期患儿的检出率(34.7%)高于其他患儿;碳青霉烯类耐药鲍曼不动杆菌随患儿年龄增长检出率逐渐增高(39.9%~65.4%)。结论儿童分离铜绿假单胞菌和鲍曼不动杆菌对各种抗菌药物的耐药率呈锯齿形变化,对大多抗菌药物的耐药率有下降趋势。不同年龄段患儿中碳青霉烯类耐药菌株的检出率不同。不发酵糖革兰阴性杆菌的分布特征和不同菌属菌株的耐药特征存在差异。因此,在儿科对此类菌进行耐药监测十分必要。

The sequence of the rice genome holds fundamental information for its biology, including physiology, genetics, development, and evolution, as well as information on many beneficial phenotypes of economic significance. Using a "whole genome shotgun" approach, we have pro-duced a draft rice genome sequence of Oryza sativa ssp. in-dica, the major crop rice subspecies in China and many other regions of Asia. The draft genome sequence is constructed from over 4.3 million successful sequencing traces with an accumulative total length of 2214.9 Mb. The initial assembly of the non-redundant sequences reached 409.76 Mb in length, based on 3.30 million successful sequencing traces with a total length of 1797.4 Mb from an indica variant cultivar 93-11, giving an estimated coverage of 95.29% of the rice genome with an average base accuracy of higher than 99%. The coverage of the draft sequence, the randomness of the sequence distribution, and the consistency of BIG-ASSEM-BLER, a custom-designed software package
