目的分析妊娠期糖尿病并发尿路感染患者的临床特征及病原菌分布特点。方法选取我院妇产科接诊的167例妊娠期糖尿病并发尿路感染患者为本次研究对象。收集患者临床资料并采集清洁中段尿进行病原菌鉴定。对分离出的大肠埃希菌进行β-内酰胺酶(ESBLs)检测及药敏试验,采用聚合酶链反应(PCR)检测CTX-m.、TEm.、SHV型基因的携带情况。结果167例妊娠糖尿病合并尿路感染患者,多发生于孕晚期(40.12%,67/167),主要为肾盂肾炎(44.91%,75/167),以尿频、尿急、尿痛单纯尿路刺激症状起病为主(36.50%,50/137)。共检出病原菌167株,其中革兰阴性菌117株(70.06%,117/167),主要为大肠埃希菌,革兰阳性菌41株(24.55%,41/167),主要为粪肠球菌,真菌9株(5.39%,9/167),主要为白色假丝酵母菌。66株大肠埃希菌中,31株为产ESBLs大肠埃希菌(46.97%,31/66),35株为非产ESBLs大肠埃希菌(53.03%,35/66)。产ESBLs大肠埃希菌对氨苄西林、头孢曲松、氨曲南的耐药率为100%,对头孢他啶、环丙沙星、左氧氟沙星、庆大霉素、复方新诺明的耐药率高于50%,分别为51.61%、80.65%、54.84%、61.29%、74.19%,对亚胺培南、哌拉西林/他唑巴坦、阿米卡星的耐药率低于20%,分别为16.13%、0%、6.45%。非产ESBL大肠埃希菌对氨苄西林、氨曲南、环丙沙星的耐药率高于50%,分别为74.29%、57.14%、54.29%,对头孢他啶、头孢吡肟、亚胺培南、哌拉西林/他唑巴坦、阿米卡星的耐药率低于20%,分比为8.57%、5.71%、5.71%、0%、2.86%。18株产ESBLs大肠埃希菌携带一种基因型,其中10株CTX-m.基因扩增阳性,5株TEm.基因扩增阳性,3株SHV型基因扩增阳性。13株携带两种及两种以上基因型,其中7株同时携带CTX-m.TEm.基因,3株同时携带CTX-m.SHV型基因,2株同时携带TEm.SHV型基因,1株同时携带CTX-m.TEm.SHV型基因。结论妊娠期糖尿病合并尿路感染患者多发于孕晚期,以尿频、尿急、尿痛单纯尿路刺激症状起病为主,病原菌主要为大肠埃希菌。产ESBLs大肠埃希菌对临床常见抗菌药物的耐药率高于非产ESBLs大肠埃希菌,产ESBLs大肠埃希菌基因型以CTX-m.主,临床上应重点关注,及时给予干预治疗。

背景:研究表明较薄移植物视力恢复更快、排斥风险更低,国内缺乏对内皮移植术后不同植片厚度的临床疗效分析,因此,确定最佳移植物厚度对于提高手术疗效至关重要。目的:评价简易后弹力层剥离内皮角膜移植术后不同植片厚度对视力恢复及其他预后指标的影响。方法:选取2013年1月至2023年2月在北部战区总医院接受简易后弹力层剥离内皮角膜移植手术治疗的角膜内皮失代偿患者共72例(72眼),其中薄植片组(m.32例(32眼),厚植片组(≥100μm.40例(40眼)。随访1年,观察两组术前及术后1,3,6,12个月的最佳矫正视力,术后1年角膜内皮细胞数、角膜植片透明度、术后并发症、植片生存情况。结果与结论:①两组患者术后视力较术前均有显著提高,薄植片组患者术后3个月最佳矫正视力优于厚植片组(P0.05);③两组患者继发性青光眼、植片免疫排斥、植片移位等术后并发症发生率比较差异无显著性意义(P>0.05);④两组术后1年植片生存率比较差异无显著性意义(93.8%,92.3%,P>0.05);⑤结论:简易后弹力层剥离内皮角膜移植术是一种安全有效的角膜内皮移植手术方式,其术后疗效与传统后弹力层剥离内皮角膜移植术相似,而且植片植入方式更为简便。较薄植片能够更早提供最佳矫正视力,更早完成角膜重塑,因此在治疗角膜内皮失代偿疾病时,优先选择薄移植物来提高恢复时间。

S 6010(US) with nanocrystals of zeolitic im.dazolate fram.works(ZIF-300) in varying degrees. Solution-casting technique was used to fabricate various m.m. to optim.ze their CO_2 capturing perform.nce from.both dry and wet gases. The prepared com.osite m.m.ranes indicated enhanced filler-polym.r interfacial adhesion, consistent distribution of nanofiller, and therm.lly established m.trix configuration. CO_2 perm.ability of the m.m.ranes was enhanced as dem.nstrated by gas sorption and perm.ation experim.nts perform.d under both dry and wet conditions. As com.ared to neat Ultrason? m.m.rane, CO_2 perm.ability of the com.osite m.m.rane doped with 40 wt% ZIF-300 nanocrystals was increased by four tim.s without disturbing CO_2/N_2 ideal selectivity. In contrast to m.jority of previously reported m.m.ranes, key features of the fabricated m.m. include their structural stability under hum.d conditions coupled with better and unaffected gas separation perform.nce.
