The 'ECU-1'environmental control units are applied to severely disabld individuals for operating home electrical equipments without other's help.They can freely turn on (off)lights,switch on (off)fan,watch on TV and give alarm for help,The function,principle and clinical application of 'ECU-1'is described in this paper.

A novel bioinspired phospholipid copolymer has been synthesized by the radical polymerization of poly2-Methacryloyloxyethylphosphorylcholine (MPC), stearyl methacrylate (SMA), hydroxypropyl methacrylate (HPMA) and trimethoxysilylpropyl methacrylate (TSMA). Contact angle results indicated that the coating surface rearranged to get a more hydrophilic surface at the polymer/water interface. The membrane mimic phosphorylcholine coating surface could resist the platelet adhesion and prolong plasma recalcification time significantly. Rapamycin was used as model drugs to prepare drug-eluting coating. The animal experiments showed that this novel drug-eluting stent could effectively prevent the phenomena of restenosis.

康复医学是以恢复患者功能为中心的医学分支。因此，功能评定无论是在客观地评定患者的功能方面，还是在最终评定治疗结果和康复效率方面都是极为重要的。全面的功能评定包括躯体、精神、言语和社会四个方面。其中，言语、社会功能和认知功能中的思维方式，都具有强烈的民族文化色彩。因此，每个国家都应该有切合自己国情的功能评定方法。但由于我国康复医学发展较晚，至今尚无一套既切合国情，又全面、实用和可靠的功能评定方法。有鉴于此，我们在“中心”顾问室、神经康复科、脊髓损伤康复科、言语治疗科、心理科和老年病科的通力合作下，经过近2年的研究，在吸收国际先进经验的基础上，密切结合国情，设计了本文所述的综合功能评定法。其优点有：1．在饮食、起居等生活方式方面以及在言语、社会、思维等方面，均切合我国国情。2．评定结果采用群众熟悉的100分制，使医务人员、患者和患者家属均易于理解，便于交流和沟通。3．在言语、认知等功能的评定方面，直接由言语和心理学家选择一些简易的言语和心理学测试项目，提高了量表的准确性、全面性和可靠性。4．各项评定指标的量化程度高，在言语、认知和社会方面尤其如此，克服了一些量表中对此类项目的评定指标不够具体和不易掌握的不足。5.简便实用，一次检查对正常人仅需20分钟左右，对患者则无负担。6.本法已在128名正常人中应用，并求出了正常值，据此拟定了功能障碍严重程度的等级，可供参考和应用。7.信度经过检验，证明可靠。 综合功能评定法的正常值、功能障碍严重程度分级及信度研究结果，将陆续报道。

Objective:To analyze the pathologic features of responses to neoadjuvant immunotherapy of squamous cell carcinoma (SCC) of the lung.Methods:The study included 31 patients with resected lung SCC post neoadjuvant immunotherapy. All patients were recruited from the neoadjuvant anti-PD-1 (Sintilimab) phase Ⅰb clinical trial (ChiCTR-OIC-17013726). The histopathological morphology and different degrees of pathologic response to immunotherapy were evaluated basing on irPRC standard.Results:According to the percentage of residual viable tumor (% RVT), pathologic responses of complete pathologic response (cPR), major pathologic response (MPR) and non-MPR were noted in 19% ( n=6), 29% ( n=9), and 52% ( n=16) of patients respectively. In addition, extensive immune activation phenomena (immune cell infiltration, including infiltration of lymphocytes, plasma cells, foamy macrophages, lymphocyte aggregation and tertiary lymphoid structures formation) and tissue repair features (giant cells, granuloma formation, proliferative fibrosis and neovascularization) were observed in tumor regression bed. Conclusions:Neoadjuvant immunotherapy has favorable effect on lung SCC. Pathologic assessment of resected lung cancer specimens after neoadjuvant immunotherapy shows unique histopathological features consistent with its mechanism.
