RESUMEN

Objective: To analyze the trend of incidence and mortality of thyroid cancer and estimate its age-period-cohort effect in Shandong Province from 2012 to 2022. Methods: The Joinpoint regression was used to analyze the trend of incidence and mortality of thyroid cancer and calculate the average annual percentage change (AAPC) based on the data on thyroid cancer from 2012 to 2022. The age-period-cohort model was used to analyze the age-effect, time-effect and cohort-effect of thyroid cancer risk in the population aged over 20 years. Results: From 2012 to 2022, the incidence of thyroid cancer in Shandong province showed a significant upward trend, with an AAPC of 21.68% (95%CI: 19.14%-24.27%, P<0.001). The incidence of females was higher than that of males, and the incidence of urban areas was higher than that of rural areas. The trend of thyroid cancer mortality was relatively stable with an AAPC of -3.04% (95%CI:-8.81%-3.09%, P=0.323). The age effect of incidence increased with age before 60 years old and decreased with age after 60 years old. The incidence peaked in the age group of 55-59. The period effect increased with time. The cohort effect showed that the cohort born before 1957 had a downward trend over time, while the cohort born after 1957 had an upward trend. Conclusion: The incidence of thyroid cancer in Shandong shows a rising trend from 2012 to 2022. Age is an important factor affecting the risk of thyroid cancer. The mortality of thyroid cancer remains stable.

RESUMEN

ObjectiveThe advent of atomic force microscope (AFM) provides a powerful tool for the studies of life sciences. Particularly, AFM-based indentation assay has become an important method for the detection of cellular mechanics, yielding numerous novel insights into the physiological and pathological activities from the single-cell level and considerably complementing traditional biochemical ensemble-averaged assays. However, current AFM indentation technology is mainly dependent on manual operation with low efficiency, seriously restricting its practical applications in the field of life sciences. Here, a method based on the combination of deep learning image recognition and AFM is developed for precisely and efficiently detecting the mechanical properties of single isolated cells and clustered cells. MethodsThe YOLO deep learning algorithm was used to recognize the central region of the cell in the optical image, the dual UNet neural network with an embedded vision transformer (ViT) module was used to recognize the peripheral regions of cell, and the template matching algorithm was used to recognize the tip of spherical probe. Based on the automatic determination of the positional relationships between the microsphere tip and the different parts of cell, the AFM tip was accurately moved to the central and peripheral regions of the target cell for rapid measurements of cell mechanical properties. Two types of cells, including HEK 293 cell (human embryonic kidney cell) and HGC-27 cell (human undifferentiated gastric cancer cell), were used for the experiments. The Hertz model was applied to analyze the force curves obtained on cells to obtain cellular Young’s modulus. ResultsAFM probe can be precisely moved to the different parts (central areas and peripheral areas) of cells to perform mechanical measurements under the guidance of deep learning-based optical image automatic recognition. The experimental results show that the proposed method is not only suitable for single isolated cells, but also suitable for clustered cells. ConclusionThe research demonstrates the great potential of deep learning image recognition to aid AFM in the precise and efficient detection of cellular mechanical properties mechanics, and combining deep learning-based image recognition with AFM will benefit the development of high-throughput AFM-based methodology to measure the mechanical properties of cells.

RESUMEN

The mortality of female breast cancer in Shandong Province has increased since the 1970. The differential decomposition analysis found that the slight decline in the crude mortality of breast cancer among women was entirely due to non-demographic factors during the 1970-1990, and the significant increase in the crude mortality was due to a combination of demographic and non-demographic factors since the 1990. The contribution rate of demographic factor has gradually increased from 53.5% in 2004-2005 to 59.5% in 2011-2013, while that of non-demographic factor has decreased from 46.5% to 40.5%. The women aged 45-64 years old were the major population of female breast cancer deaths, accounting for 40%-60% of total breast cancer deaths in different times, and then the mortality in female aged 55-64 years old increased rapidly, with increases of 52.12%, 115.19% and 29.01% in 2011-2013 over the 1970-1974, 1990-1992 and 2004-2005, respectively (Z=-7.342,P<0.001). Compared with 1970-1974, the age-standardized mortality rate of rural women increased by 41.86% in 2011-2013 (Z=-17.933, P<0.001), and that of urban women increased by 18.62% in 2011-2013 (Z=-25.642, P<0.001). The age-standardized mortality rate of breast cancer in urban women was higher than that in rural women in different times (all P<0.05). The spatial scan analysis found that eastern Shandong Province was found to be a sustained high-risk area for death, and other high-risk areas were transferred from north to southwest of Shandong between 1970 and 2013.

RESUMEN

<p><b>BACKGROUND</b>The relationship between monosymptomatic resting tremor (mRT) and Parkinson's disease (PD) remains controversial. In this study, we aimed to assess the function of presynaptic dopaminergic neurons in patients with mRT by dopamine transporter positron emission tomography (DAT-PET) and to evaluate the utility of clinical features or electrophysiological studies in differential diagnosis.</p><p><b>METHODS</b>Thirty-three consecutive patients with mRT were enrolled prospectively. The Unified Parkinson's Disease Rating Scale and electromyography were tested before DAT-PET. Striatal asymmetry index (SAI) was calculated, and a normal DAT-PET was defined as a SAI of <15%. Scans without evidence of dopaminergic deficits (SWEDDs) were diagnosed in patients with a subsequent normal DAT-PET and structural magnetic resonance imaging.</p><p><b>RESULTS</b>Twenty-eight mRT patients with a significant reduction in uptake of DAT binding in the striatum were diagnosed with PD, while the remained 5 with a normal DAT-PET scan were SWEDDs. As for UPRDS, the dressing and hygiene score, walking in motor experiences of daily living (Part II) and motor examination (Part III) were significant different between two groups (P < 0.05 and P < 0.01, respectively). Bilateral tremor was more frequent in the SWEDDs group (P < 0.05). The frequency of resting tremor and the amplitude of postural tremor tend to be higher in the SWEDDs group (P = 0.08 and P = 0.05, respectively).</p><p><b>CONCLUSIONS</b>mRT is heterogeneous in presynaptic nigrostriatal dopaminergic degeneration, which can be determined by DAT-PET brain imaging. Clinical and electrophysiological features may provide clues to distinguish PD from SWEDDs.</p>

RESUMEN

The shape and structure of granules are controlled by the granulation process, which is one of the main factors to determine the nature of the solid dosage forms. In this article, three kinds of granules of a traditional Chinese medicine for improving appetite and promoting digestion, namely, Jianwei Granules, were prepared using granulation technologies as pendular granulation, high speed stirring granulation, and fluidized bed granulation and the powder properties of them were investigated. Meanwhile, synchrotron radiation X-ray computed micro tomography (SR-µCT) was applied to quantitatively determine the irregular internal structures of the granules. The three-dimensional (3D) structure models were obtained by 3D reconstruction, which were more accurately to characterize the three-dimensional structures of the particles through the quantitative data. The models were also used to quantitatively compare the structural differences of granules prepared by different granulation processes with the same formula, so as to characterize how the production process plays a role in the pharmaceutical behaviors of the granules. To focus on the irregularity of the particle structure, the box counting method was used to calculate the fractal dimensions of the granules. The results showed that the fractal dimension is more sensitive to reflect the minor differences in the structure features than the conventional parameters, and capable to specifically distinct granules in structure. It is proved that the fractal dimension could quantitatively characterize the structural information of irregular granules. It is the first time suggested by our research that the fractal dimension difference (Df,c) between two fractal dimension parameters, namely, the volume matrix fractal dimension and the surface matrix fractal dimension, is a new index to characterize granules with irregular structures and evaluate the effects of production processes on the structures of granules as a new indicator for the granulating process control and optimization.
