Dear Editor,Plant cell walls are complex and dynamic structures that are mainly composed of polysaccharide polymers such as cellulose,hemicellulose,and pectin,in addition to substantial amounts of the non-saccharide polymer lignin(McFarlane et al.,2014;German et al.,2023).The components of cell walls are interconnected in various ways to form a complex,multilayered network structure(Wen et al.,2023).

促进科技成果转化一直是我国科技创新政策关注的重点。但是,由于科技成果的特殊性、复杂性和专业性,使得科技成果转化难成为世界各国面临的共性问题。我国的科技成果转化工作同样存在许多值得商榷和探索的地方,尤其是对于科研院所是否能以创办企业的方式做成果转化,还存在争议。文章以信息技术领域为例,通过分析知识产权许可转让、产学研合作、创办企业等几种主要的成果转化形式的优缺点和适用场景,对这个问题发表一点看法。

目的:探讨2020-2021年长治地区咽峡炎链球菌群(SAG)感染的临床特征及耐药性。方法:收集189例SAG感染患者资料进行临床特征分析,使用WHONET5.6软件对SAG菌株类型及药敏结果进行统计,并对不同感染部位菌株药物耐药率作比较分析。结果:长治地区SAG阳性病例中,男性(61.90%)多于女性(38.10%);平均年龄(51.0±14.5)岁;有脓肿形成的患者117例(61.90%),中间链球菌形成脓肿的概率最大;SAG所致感染类型以口腔感染(49例,25.93%)、腹腔感染(36例,19.05%)为主;SAG血流感染组患者合并基础疾病比例、存在免疫抑制比例、住院天数及炎性指标值(C反应蛋白、血清淀粉样蛋白A、降钙素原)高于非血流感染组患者(P<0.05);SAG对克林霉素、红霉素、四环素、左旋氧氟沙星耐药率分别为73.04%、65.14%、38.62%、9.00%,对其他种类抗生素未见耐药;口腔、腹腔、泌尿生殖系统3个感染部位SAG分离株对左旋氧氟沙星耐药率组间差异有统计学意义(P<0.05),泌尿生殖系统感染部位SAG分离株对左旋氧氟沙星耐药率较口腔、腹腔感染部位分离株耐药率明显升高(P<0.05)。结论:SAG感染患者若合并基础疾病、存在免疫抑制,且炎性指标值明显升高时,应注意患者是否发生SAG血流感染;SAG对大环内酯类及林可酰胺类药物耐药率较高。
