目的:探讨浙江省1型糖尿病(T1DM)住院患者的临床特征及管理现状。方法:为横断面研究。选择2016年10月至2022年7月于浙江省10家医院住院的T1DM患者作为研究对象。收集患者的一般临床资料(包括起病年龄、性别、住院天数、病程)、实验室指标[包括生化、糖化血红蛋白、餐后2 h血糖、胰岛素、C肽、谷氨酸脱羧酶抗体(GADA)、蛋白酪氨酸磷酸酶抗体(IA-2A)、胰岛素自身抗体(IAA)、胰岛细胞抗体(ICA)]、并发症筛查情况(包括尿白蛋白/肌酐比值检测、眼底照相、肌电图、颈动脉超声、双下肢动脉超声及四肢多普勒超声)、治疗方案(包括胰岛素治疗方案及联用降糖药的情况)等。按照就诊时间将T1DM患者分为2016年10月至2019年8月组及2019年9月至2022年7月组,比较两组慢性并发症筛查率、检出率及抗体检测率等情况。组间比较采用 χ2检验。结果:共564例T1DM患者纳入本研究。患者的年龄从1岁到84岁不等,其中成人(≥18岁)390例,儿童和青少年(<18岁)174例。T1DM患者的住院天数、起病年龄和病程中位数分别为7(6,10)d、29(16,45)岁和3(0,8)年。其中,56.6%(319/564)的T1DM患者有急性并发症,49.6%(280/564)的T1DM患者有慢性并发症。56.9%(321/564)的T1DM患者有合并症,包括血脂异常[25.7%(145/564)]、高血压[12.2%(69/564)]、高尿酸血症[8.2%(46/564)]、自身免疫性甲状腺疾病[9.0%(51/564)]、肥胖症[4.8%(27/564)]。糖尿病肾脏病、糖尿病视网膜病变、糖尿病周围神经病变及糖尿病周围血管病变的筛查率分别为71.5%(403/564)、58.9%(332/564)、55.5%(313/564)及80.7%(455/564),相应的检出率分别为21.6%(87/403)、27.4%(91/332)、47.0%(147/313)和31.6%(144/455)。99.5%(561/564)的T1DM患者使用胰岛素治疗。每日多次胰岛素注射治疗占比最高,为78.7%(444/564)。除胰岛素外,34.0%(192/564)的T1DM患者还联用非胰岛素类药物,α-葡萄糖苷酶抑制剂是最常用的药物[53.6%(103/192)]。2019年9月至2022年7月组GADA、IA-2A、ICA、IAA检测率高于2016年10月至2019年8月组( P<0.05)。并发症筛查中,除糖尿病肾脏病外,2019年9月至2022年7月组患者慢性并发症筛查率均比2016年10月至2019年8月组高,包括视网膜病变、周围神经病变、周围血管病变筛查率均提高( P<0.05)。结论:浙江省T1DM患者主要是成人起病。近年来,浙江省T1DM患者的糖尿病并发症筛查率及抗体检测率呈上升趋势,体现了浙江省对T1DM住院患者的管理较前更加规范,但糖尿病抗体检测率及并发症的筛查率仍较低,有待进一步提高。

该文探讨了T细胞免疫球蛋白黏蛋白3(T cell immunoglobulin and mucin domain-containing protein 3,TIM-3)基因沉默对靶向ROR1的嵌合抗原受体(ROR1-CAR)修饰的T细胞增殖和抗肿瘤免疫应答的影响及其作用机制。通过短发夹RNA(short hairpin RNA,shRNA)基因沉默技术长效抑制TIM-3在ROR1-CAR T细胞中的表达,采用qRT-PCR和Western blot实验检测TIM-3在mRNA和蛋白水平的表达情况;采用ELISA实验验证TIM-3基因沉默的ROR1-CAR T细胞对靶细胞的杀伤能力的影响;流式细胞检测进一步评估抑制TIM-3表达对ROR1-CAR T细胞的靶向杀伤和抗原依赖性的增殖能力的影响。结果显示,shRNA可显著抑制TIM-3在ROR1-CAR T细胞中的表达,但不影响ROR1-CAR T细胞的百分比和增殖活性;通过检测发现ROR1阳性的人结肠癌细胞系SW620分泌高水平的TIM-3配体—半乳凝素9(Galectin-9),该配体可直接作用于ROR1-CAR T细胞而发挥免疫负调控作用。另外,长效抑制TIM-3的表达促进了ROR1-CAR T细胞的抗原依赖性的细胞因子释放和增殖。总之,消除ROR1-CAR T细胞表面的TIM-3与肿瘤细胞来源的Galectin-9之间的相互作用可有效增强ROR1-CAR T细胞的抗肿瘤活性。

Ⅰ.INTRODUCTION The direct detection of dark matter particles,especially the weakly interacting massive particles(WIMPs),is being actively carried out by a couple of experiments worldwide[1].In recent years,the PandaX-Ⅱ experiment located in the China Jinping Underground Laboratory(CJPL)[1-3],which uses the technology of dual phase liquid xenon time projection chambers(TPCs),has pushed the limits of the cross section between WIMPs and nucleons to a new level for most of the possible WIMP masses;other experiments of the same type are also being performed[4–10].
