在许多医院都安装了生产短寿命放射性同位素的回旋加速器,但用于质子治疗的回旋加速器还处于起步阶段。质子治疗可以达到精确的幅照剂量分布,质子能量决定了穿透深度,因而产生的能量释放点可以精确控制,技术先进。由于质子束传播的线形度好,引起的横向二次散射小,肿瘤前端的健康组织接受的剂量很小,在其周围和之后的组织几乎就没有照射剂量,因此质子束治疗是一种非常有效的方法。束流传输到治疗房间的效率,束流的能量控制、强度及位置的稳定性,快速而精确的改变束流参数来满足临床需要等,都是关键。开发安装于医院的并可满足病人实际需要的质子治疗回旋加速器,包括束流输运系统和一系列的控制系统都相当复杂,文章提出了用于该目的的概念框图和建议。

18F-FLT PET能监测食管鳞癌放疗过程中肿瘤和正常组织的生物学变化,其较18F-FDG PET能较好区分炎症和肿瘤,能检测食管肿瘤放疗过程中的加速再增殖,18F-FETNIM PET能检测食管鳞癌的乏氧状态,18F-FLT PET和18F-FETNIM PET作为一种非创伤性的影像学技术,能为肿瘤医生提供一个早期评价治疗反应,检测放疗过程中的再增殖克隆源细胞、乏氧和评价新辅助治疗疗效的手段。18F-FLT PET和18F-FETNIM PET能为放射治疗确定“再增殖”和“乏氧”生物学靶区,以通过剂量调强放疗提高再增殖和乏氧区域放疗剂量,提高肿瘤的局部控制率和远期生存。

Philadelphia chromosome-positive acute myeloid leukemia is controversial and difficult to distinguish from the blast phase of chronic myeloid leukemia. As a myeloid neoplasm, rare cases of this leukemia manifest multiple soft-tissue tumors or bone lytic lesions. In this paper, we describe a 49-year-old male patient who had an abrupt onset with sharp chest pain, fever, fatigue, emaciation, and splenomegaly. 18F-fluoro-deoxy-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) result showed diffuse and uneven hypermetabolic lesions in the bone marrow with peripheral bone marrow expansion, multiple soft tissue neoplasms with high 18F-FDG uptake, and lytic bone lesions. Bone marrow smear and biopsy detected aberrant blast cells expressing myeloid rather than lymphoid immunophenotype marker. For the existence of Philadelphia chromosome and BCR-ABL1 fusion gene together with complex chromosome abnormalities, a diagnosis of Philadelphia-positive acute myeloid leukemia was made, although the type (de novo or blast crisis) remained unclear.

As valuable land in the ocean, coral islands are not only important bases for making use of marine resources and protecting marine rights and interests, but also important for breakthrough research in many fields of earth science. Hence, the economical and efficient determination of the underground structure of coral islands has become significant in coral island engineering geology, but remains challenging for traditional marine geophysical prospecting and drilling methods. While ambient noise tomography with dense arrays has been widely used in continental regions, its applicability to coral islands remains undetermined. In this study, based on the data recorded by a dense array on an isolated coral island in the South China Sea, we analyzed the ambient noise characteristics and obtained a 3D subsurface structure of the coral island using ambient noise tomography. We made the following findings: ① The ambient noise frequencies can be roughly categorized into three levels: < 1, 1–5, and > 5 Hz. The spectral characteristics of the noise below 5 Hz were consistent at different stations, but there were significant differences in the characteristics of the noise above 5 Hz. ② For ambient noise frequencies below 5 Hz, cross-correlation functions with high quality could be obtained with only 24 h of waveform data. However, it was difficult to extract meaningful cross-correlation functions for ambient noise frequencies above 5 Hz. ③ The S-wave velocity in the coral island was higher toward the sea and lower toward the lagoon, which was consistent with the high degree of cementation of the outer reef flat stratum on the seaward side. ④ There were two low-velocity horizons at 25–75 and 200–300 m, which were in good agreement with the high-porosity horizons that were revealed by drilling core samples, reflecting the weathering history of the reef. Our research demonstrates that ambient noise tomography is a potentially economical, efficient, and environmentally friendly method for the geological prospecting of coral reefs.
