From January 2013 to January 2015, 19 patients of traumatic hemothorax with hemorrhagic shock were treated in our department by thoracoscopic surgery combined with autologous blood transfusion. This study retrospectively analyzed the therapeutic effect and shared our experience. The average amount of blood transfused back was 662.41 ml ± 269.15 ml. None of the patients developed transfusion reaction and were all discharged uneventfully. Thoracoscopic surgery combined with autologous blood transfusion is effective in the rescue of patients with progressive hemothorax and hemorrhagic shock. When corresponding indications are well managed, treatment for these patients is quicker, safer, and more effective.

背景与目的:细胞色素P450花生四烯酸表氧化酶(cytochrome P450 arachidonic acid epoxygenase 2J2,CYP2J2)作为花生四烯酸的新型代谢途径,在人体中的生物学及病理生理学意义还远未被认识和阐明。本研究主要探讨CYP2J2基因在人类肿瘤组织及肿瘤细胞系中的表达及其意义。方法:采用RT-PCR、Western blot和免疫组化法检测CYP2J2在130例不同类型的人癌组织及相应的癌旁正常组织,4例炎性假瘤组织以及8种常见人源肿瘤细胞系和两种非肿瘤细胞系中的表达情况。结果:CYP2J2在78%(101例)的癌组织中特异性高表达,而癌旁正常组织未能检测到CYP2J2表达,而且CYP2J2 mRNA和蛋白表达水平呈高度的相关性(r=0.613,P<0.01)。同样,免疫组化结果分析发现78%肿瘤组织中有CYP2J2表达,而癌旁正常组织及4例炎性假瘤均阴性。此外还发现CYP2J2主要在肿瘤细胞中表达,而周围的炎性细胞及间质组织均无CYP2J2表达。8种肿瘤细胞中均高表达CYP2J2,而非肿瘤细胞系则无CYP2J2表达。结论:CYP2J2在肿瘤细胞中选择性高表达,CYP2J2可能是肿瘤发生发展的一个标志物。

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.

目的探讨CT引导下注射亚甲蓝联合贝朗胶行肺部磨玻璃结节(GGO)术前定位在单孔胸腔镜手术中的应用。方法回顾分析该院2015年6月-2017年10月收治的30例GGO患者的临床资料,术前采用CT引导下注射亚甲蓝联合贝朗胶定位,观察操作的安全性和有效性。结果所有患者均顺利定位,定位时间15~32 min,平均时间(20.1±4.7)min;气胸1例,血气胸1例,无咯血及胸膜反应等严重并发症。28例患者行楔形切除,自置入胸腔镜至取出楔形标本,共用时5~22 min,平均(20.0±4.5)min,2例患者因楔形标本无法确认肿瘤而直接行肺段切除术。所有患者无中转开胸。结论该项操作简便快捷,并发症少,大大缩短了术中探查的时间、减少了切除范围过大、误切及中转开胸的概率,值得进一步推广应用。

Nonadiabatic holonomic quantum computers serve as the physical platform for nonadiabatic holonomic quantum *** quantum computation has entered the noisy intermediate-scale era, building accurate intermediate-scale nonadiabatic holonomic quantum computers is clearly necessary. Given that measurements are the sole means of extracting information, they play an indispensable role in nonadiabatic holonomic quantum computers. Accordingly, developing methods to reduce measurement errors in nonadiabatic holonomic quantum computers is of great importance. However, while much attention has been given to the research on nonadiabatic holonomic gates, the research on reducing measurement errors in nonadiabatic holonomic quantum computers is severely lacking. In this study, we propose a measurement error reduction method tailored for intermediate-scale nonadiabatic holonomic quantum computers. The reason we say this is because our method can not only reduce the measurement errors in the computer but also be useful in mitigating errors originating from nonadiabatic holonomic gates. Given these features,our method significantly advances the construction of accurate intermediate-scale nonadiabatic holonomic quantum computers.

Let Gi be closed Lie groups of U (n), Ω i be bounded Gi-invariant domains in C^n which contains 0, and O(C^n)^Gi = C, for i = 1, 2. It is known that if f : Ω 1 → Ω 2 is a proper holomorphic mapping, and f^-1{0} = {0}, then f is a polynomial mapping. In this paper, we provide an upper bound for the degree of such a polynomial mapping using the multiplicity of f .
