SUMMARY
For regenerative cell therapies using pluripotent stem cell (PSC)-derived cells, large quantities of purified cells are required. Magnetic-activated cell sorting (MACS) is a powerful approach to collect target antigen-positive cells; however, it remains a challenge to purify various cell types efficiently at large scale without using antibodies specific to the desired cell type. Here we develop a technology that combines microRNA (miRNA)-responsive mRNA switch (miR-switch) with MACS (miR-switch-MACS) to purify large amounts of PSC-derived cells rapidly and effectively. We designed miR-switches that detect specific miRNAs expressed in target cells and controlled the translation of a CD4-coding transgene as a selection marker for MACS. For the large-scale purification of induced PSC-derived cardiomyocytes (iPSC-CMs), we transferred miR-208a-CD4 switch-MACS and obtained purified iPSC-CMs efficiently. Moreover, miR-375-CD4 switch-MACS highly purified pancreatic insulin-producing cells and their progenitors expressing Chromogranin A. Overall, the miR-switch-MACS method can efficiently purify target PSC-derived cells for cell replacement therapy.

【摘要】目的 探寻在眼部整形美容术后实行局部冷敷处理的效果。方法 选择我院收治的 60 例眼部整形美容术患者，随机平分成对照组和观察组，分别实行术后常规处理和局部冷敷处理，对比效果。结果 观察组创口开始好转时间（2.11±1.24）、创口基本愈合时间（5.67±2.04）、术眼局部肿胀消退时间（2.04±0.71）明显优于对照组（P＜0.05）；观察组术后创口疼痛程度明显低于对照组（P＜0.05）；观察组 SAS 和 SDS 评分明显低于对照组（P＜0.05），观察组睡眠质量明显高于对照组（P＜0.05）；观察组术后不良反应明显低于对照组（P＜0.05）。结论 局部冷敷处理可使眼部整形美容术后患者的临床各项指标改善，减少疼痛状况，缓解负面情绪，使睡眠质量提升，使不良反应发生率降低。

【Abstract】Objective To explore the effect of local cold compress after eye cosmetic surgery. Methods 60 patients in our hospital were randomly divided into control group and observation group, and the postoperative routine treatment and local cold application were applied respectively to compare the effect. Results The observation group (2.11 ± 1.24), basic wound healing time (5.67 ± 2.04), and local swelling regression time (2.04 ± 0.71) were significantly better than controls (P <0.05); significantly lower (P <0.05); SAS and SDS scores were significantly lower (P <0.05) (P <0.05); the observation group was significantly lower than the control group (P <0.05). Conclusion Local cold compress treatment can improve the clinical indicators of patients after eye plastic surgery, reduce the pain status, relieve the negative emotions, improve the sleep quality, and reduce the incidence of adverse reactions.
