目的介绍使用Ga-1,4,7,10-四氮杂环十二烷-1,4,7,10-四乙酸(DOTA)-0-~3-奥曲肽(DOTATATE) PET/CT进行颈动脉体副神经节瘤(CBP)基线评估的经验。方法对5例CBP患者(女4例,男1例,年龄24～73岁)治疗前的Ga-DOTATATE PET/CT显像结果进行回顾性分析,对PET/CT图像进行视觉及半定量分析,测最大标准摄取值(SUV)。结果所有患者均为单侧CBP,在PET/CT上表现为Ga-DOTATATE高摄取,其中2例患者出现了另外的Ga-DOTATATE摄取灶,1例位于甲状腺和大脑额叶,另1例位于骨骼和肾上腺包块。5例患者中,4例患者经手术切除原发瘤,1例患者因出现转移性嗜铬细胞瘤而行Lu-DOTATATE肽受体放射性核素治疗(PRRT)。结论Ga-DOTATATE PET/CT显像对于CBP的分期、病灶检测及患者管理有重要价值,能对生长抑素受体的表达进行有效检测,也可为PRRT提供依据。

目的在儿童霍奇金淋巴瘤（HL）的治疗中,采取反应适应性治疗策略来减少不良反应非常重要,然而关于充分或不充分治疗反应的定义仍存在争议。为确定18F-脱氧葡萄糖（FDG）PET/CT（PET）预测疾病结局的最佳方法,拟对3种不同方法进行比较。方法根据修订的国际协调项目标准（IHP）和Deauville标准对72例HL患儿治疗前基线、治疗中期、治疗结束后的PET显像结果进行解读。用受试者工作特征（ROC）曲线获得治疗中期和治疗结束后FDG最大标准摄取值的变化值(△SUVmax),用于预测无进展生存（PFS）。比较定量数据与可视化图像数据预测PFS的效能。结果原发病灶治疗中期和治疗结束后平均△SUVmax分别为（77.4±19.5）%、（68.8±30.4）%,截断值为82%和73%。只有治疗结束后△SUVmax对3年PFS的预测有统计学意义（P=0.043）。根据文献报道的截断值（66%和77%）进一步分析治疗中期△SUVmax,结果仍不具统计学意义（P=0.604和0.431）。对于治疗中期评价,IHP标准与Deauville标准（P=0.002和0.001）和△SUVmax（P=0.03）相关;而对于治疗后评价,IHP标准与△SUVmax明显相关（P=0.04）,但与Deauville标准的相关性不明显（P=0.055和0.058）。1年、3年和5年PFS分别为（95.7±0.2）%、（89.6±0.4）%和（80.8±0.7）%。3种方法在预测3年PFS方面表现相当,但是治疗中期使用Deauville标准和治疗结束后使用IHP标准进行评估更具意义。3种方法都显示出较高的阴性预测价值和较低的阳性预测价值。结论在儿童HL预后评估中,治疗中期用Deauville标准解读PET显像结果优于其他方法,而在治疗结束后可以使用IHP标准进行定量分析和视觉评估。研究得出的SUVmax降低的最佳截断值是73%。

目的探讨复发性前列腺癌(PCa)患者血清前列腺特异性抗原(PSA)水平、Gleason评分与68Ga-前列腺特异性膜抗原(PSMA)PET/CT显像的关系。方法纳入109例患者(中位年龄为71岁,范围48～89岁),所有患者均为根治手术和(或)激素治疗和(或)放疗后PSA复发的患者。记录局部复发、淋巴结转移[盆腔、腹部和(或)膈上]、骨转移(单处转移、多处转移)和其他部位转移(肺、肝、脑等)。结果在91例(83.4%)患者中,68Ga-PSMA PET/CT至少检测到1处PCa病灶。血清总PSA(tPSA)中位值为6.5(0.2～640)μg/L。68Ga-PSMA PET/CT阳性与阴性患者血清tPSA差异有统计学意义,而Gleason评分差异无统计学意义。56例患者有局部复发,46例有淋巴结转移。盆腔淋巴结转移最常见,其次是腹部和膈上淋巴结。55例患者存在骨转移(20例为单发,35例为多处转移)。受试者工作特征曲线分析示血清tPSA区分阳性和阴性68Ga-PSMA PET/CT显像的最佳临界值为0.67μg/L,曲线下面积为0.952(95%CI:0.911～0.993)。结论68Ga-PSMA PET/CT是一种有效检测PCa复发的方法。尽管Gleason评分和68Ga-PSMA PET/CT显像之间无明显相关性,血清tPSA可用于预估68Ga-PSMA PET/CT阳性的可能性。

Background/Aims: Determining the levels of oral health and the quality of dental care are fundamental to building concepts of oral health. This study aims to assess toothbrushing techniques using a technical and physical model, clarifying how children and pre-adults learn to brush their teeth. Materials and Methods: Data were recorded from 23 participants, both male and female of various ages, using a proposed electronic toothbrush equipped with X-Y-Z axes pathways. The data, collected before and after training experiments, were processed with MATLAB to generate plots for the three axes. Results: The study revealed that most parameter values, such as Mean Difference Between Amplitudes (MAV, 6.00), Wilson Amplitude (WAMP, 179.419), and Average Amplitude Coupling (AAC, 1.270), decreased from before to after the experiments. Furthermore, the average overall epoch lengths (AVG) showed a 75% reduction in movement amplitude between the two experiments. Conclusion: Dentist observations indicated which brushing methods were acceptable or not. Analytical values suggest that individuals learn the toothbrushing technique effectively, and medical observations clearly demonstrate the success of the proposed method.

The （n,f, k）： F（G） system consists ofn components and the system fails （works） if and only if there are at least flailed （working） components or at least k consecutive failed （working） components. These system models can be used in electronic equipment, automatic payment systems in banks, and furnace systems. In this paper we introduce and study the （n, f, k）：F and （n, f, k）： G systems consisting of weighted components. Recursive equations are presented for reliability evaluation of these new models. We also provide some conditions on the weights to represent weighted-（n,f, k） systems as usual （n,f, k） systems.

We demonstrate the hybrid focusing points of sonic crystals for a multi-source array applied to flat sonic crystal lenses. The contributions of different point source couples form hybrid focusing points. Ray-trace analyses are conducted for acoustic flat lenses with multi-source configurations. The finite-difference time-domain （FDTD） simulation of flat lenses with multi-source configurations demonstrates the establishment of pure and hybrid focusing points in a pyramidal constellation. The number of focusing points in the pyramidal constellation depends on the number of point sources. We propose an acoustic device for fine-tuning the location of a far-field hybrid focusing point and discuss its benefits for acoustic energy focusing application.

This paper presents an overview of the floor heave management at the Glencore Bulga Underground Operations and investigates the contributing factors to the behaviour of the floor. The mine experienced a number of major floor heave events in gateroads on development. As the longwall face approached the roadways, the magnitude of floor heave frequently increased, while new floor heave also ***, severe floor heave events took place along the longwall face. The most observed failure mode was buckling. While regular floor measurements were conducted to better understand the nature of the phenomenon, and various measures were considered to control the deformation of floor, the mining height was increased for the predicted floor heave domains, which facilitated effective management of the floor issues. The experience in the mine indicates that mainly high horizontal stresses with greater depths of cover and certain types of floor lithology configuration are likely to contribute to the failures of floor strata.
