OBJECTIVE The concept of double primary lung cancer （DPLC） has been generally accepted. Recently, an increasing incidence of synchronous DPLC has been reported, while the diagnostic standard and treatment strategies remain to be improved. This study was conducted to investigate effective surgical treatment and prognosis of synchronous DPLC. METHODS From January 1983 to April 2004, 31 patients with synchronous DPLC were operated in our department. Clinical data, such as surgical pattern, postoperative complications, and survival status, of all these patients were reviewed retrospectively. RESULTS The 31 patients with synchronous DPLC accounted for 0.67% of all the 4,649 patients operated for primary lung cancer in our department during the same period. Both tumors of the synchronous DPLC were resected with Iobectomy or pneumonectomy in 12 patients, while among the other 19 patients at least 1 tumor was treated with partial pulmonary resection. The postoperative morbidity was 29%（9/31）, including 1 case of respiratory insufficiency, 3 cases of atelectasis, 2 cases of atrial fibrillation, 1 case of haemoptysis, 1 case of pleural effusion, and 1 case of wound fat necrosis. No deaths occurred during the operations or within 30 days postoperatively. The postoperative 1 -, 3-, and 5-year survival rates were 52%, 29%, and 20%, respectively. CONCLUSION The incidence of synchronous DPLC is low. An aggressive and reasonable surgical approach can achieve a satisfactory outcome in patients with synchronous DPLC. The postoperative morbidity is low. Some patients might achieve long-term survival.

目的用已构建的miR-144-GFP-H1人胚胎干细胞(human embryonic stem cell,hESC)示踪细胞株,以GFP荧光信号报告miR-144表达描述红系发生的进展程度,探究在红系发生过程中lncRNA的潜在功能并初步验证其功能影响。方法利用已构建的miR-144/451-GFP-H1细胞株(下文简称144-H1)进行体外红细胞诱导培养。以CD71,GPA表面分子描述进入红系发生阶段的细胞亚群。以miR-144的GFP报告基因为关键区分,对GFP阳性(高红系发生倾向)和阴性细胞群(低红系发生倾向)分别进行转录组测序,获取差异性表达的lncRNA。选取具备验证价值的lncRNA条目进行初步功能验证。利用CRISPR/Cas9基因编辑技术设计对应lncRNA的功能干扰方案并获取对应lncRNA功能敲除的144-H1细胞株。使用该敲除细胞株与非敲除的144-H1细胞株进行红细胞的平行诱导培养,寻找差异节点,初步验证其对在体外发育模型下对红系发生的影响效应。结果1)构建的144-H1细胞株能够在进入体外红细胞诱导阶段后表达GFP荧光蛋白,提示miR-144的启动。2)在CD71,GPA双阳群中,GFP阳性亚群和GFP阴性亚群存在显著的lncRNA表达差异。3)对多个lncRNA条目设计了能够有效干扰其功能的序列区段删除基因编辑方案。验证编辑成功。在敲除细胞株中,lncRNA的一部分序列被直接删除。4)在红细胞诱导培养的平行验证试验中,LINC01569的功能敲除株对比非敲除株表现出明显的流式亚群差异和细胞增殖能力差异:①敲除株的GFP荧光持续高表达;②敲除株CD71-GPA双阳群在红细胞成熟过中比例持续降低;③敲除株未观察到显著的血红蛋白表达,无明显红色;④敲除株细胞增殖能力远低于非敲除株(P<0.05)。结论成功利用144-H1细胞株对lncRNA在红系发育中的潜在功能进行了探究,可设计更精密的体外发育实验来提高lncRNA功能的抓取精度。在差异性表达的lncRNA条目中,LINC01569经初步验证,对红系发生过程存在调控作用。LINC01569的功能缺失严重影响红细胞的正常分化与增殖。LINC01569在红系发生过程中的具体调控机制有待进一步探索与研究。

A reversible operation protocol is provided for a weak-measured quantum entanglement state. The evolution of weak values is studied under different parameter conditions. The weak values can be extracted from the entanglement state and the weak-measured quantum entanglement state can be revived to its initial state theoretically by weak measurement and reversibility operation respectively. We demonstrate the reversible operation protocol by taking Bell's state as an example. The negativity is used to analyze the initial state, the weak-measured state and the reversed state in order to describe the evolution of quantum entanglement degree. Weak values are detected from the quantum entanglement state by weak measurement and the degree of the weak-measured quantum entanglement state can be revived to its initial state through reversible operation. The information of quantum entanglement state would be extracted from weak values detected in the process of the scheme.
