【目的】探讨纳米炭混悬液在分化型甲状腺癌合并其他甲状腺疾病行颈中央区淋巴清扫中的示踪效果差异。【方法】回顾性分析2015 年7 月至2019 年7 月梅州市人民医院收治的分化型甲状腺癌患者共500 例， 将患者分为纳米炭组（A 组）314 例及非纳米炭组（B 组）186 例，并根据无合并疾病（亚组0）、合并多结节性甲状腺肿（亚组1）、合并桥本氏甲状腺炎（亚组2）或甲状腺癌灶较大（肿瘤最大径超过30 mm，亚组3），进一步将A、B 两组分成 4 个亚组，比较各组的淋巴结检获数及术后并发症的发生情况。【结果】A 组的淋巴结检获数和转移率均多于B 组［6.0（3.0 ~ 9.0）vs. 3.0（1.0 ~ 5.3），P < 0.001；24.4% vs. 20.7%，P = 0.041）］；A0 组、A1 组、A2 组的淋巴结检获数均多于B0［8.0（6.0~11.0）vs. 3.0（2.0 ~ 6.0），P < 0.001）］、B1［4.0（3.0 ~ 6.8）vs. 3.0（0.0 ~ 5.0），P < 0.001）］、 B2［8.0（5.0 ~ 12.0）vs. 4.0（0.0 ~ 6.5），P = 0.002］组。同为术中使用纳米炭，A1、A3 组的淋巴结检获数显著少于 A0 组［4.0（3.0~6.8）vs. 8.0（6.0 ~ 11.0），P < 0.001；3.0（2.0 ~ 6.0）vs. 8.0（6.0 ~ 11.0），P < 0.001）］；A1、A2、A3 组和 A0 组相比，声嘶的发生率均无统计学意义（P > 0.05），A2、A3 组术后甲状旁腺功能减退的发生率显著高于A0 组（51.8% vs. 34.1%，P < 0.05；54.2% vs. 34.1%，P < 0.05）。【结论】分化型甲状腺癌术中应用纳米炭可提高淋巴结的检获数，无合并疾病的作用效果最佳，合并多结节性甲状腺肿、癌灶过大可影响纳米炭的示踪效果，当癌灶最大径大于30 mm 时应用纳米炭对淋巴结的检出无明显作用。

Calcific aortic valve disease (CAVD) is the most common disease affecting the heart valves, characterized by thickening, fibrosis, and mineralization of the aortic valve leaflets. Currently, there is no effective pharmacological treatment. Aortic valve calcification is a complex and multifactorial process involving valve inflammation, fibrosis, calcification, valve thickening and outflow tract obstruction. The exact pathophysiological mechanisms of CAVD are not fully understood, but many studies have suggested that innate immune cells play a key role in the development of aortic valve calcification. This review focuses on the current role of innate immune cells in the development of CAVD. [ABSTRACT FROM AUTHOR]

mono-p-toluenesulfonyl-α-cyclodextrin ester(mono-OTs-α-CD) is an important intermediate for the preparation of other mono-derivatives of α-CD. In this paper, a new liquid chromatography method for the determination of toluenesulfonylation products of α-cyclodextrin was established. Mono-OTs-α-CD on three different carbon sites (C3,C2 and C6) was completely separated on ODS column, and the retention time was 7.70.10.08 and 12.18 min, respectively. The linear regression equations were y-89.176.x-559.19(R²-0.9990).y=87.917x-430.16(R²=0.9996), and y 70.529x-24.259(R²=0.999 0) over concentration range from 5 to 500 mg L-1, respectively. The recovery was 92.5~102.3% with RSDs(<1.8%), and the LOD was less than 0.5 mg L-1, which indicated that high accuracy and precision of this method could meet the monitoring requirements of the above products. The effects of raw material ratio, temperature, time and pH value of the reaction system on the mono-substitution reaction were preliminarily investigated. The optimized conditions(molar ratio of 1: 2. reaction temperature of 15 °C. reaction time of 15 min) were obtained with a yield of 34.84% (n=3) for mono-3-OTs-α-CD. [ABSTRACT FROM AUTHOR]

In 1928, Karl Ludvig Reichelt (1877-1952) went to Taiwan to pay a special visit to the Venerable Luo Miaochi (1904-1930), the then Vice-abbot of Bangka Lungshan Temple, in Taipei. The two then established a memorable friendship and initiated a meaningful discussion on the possibility of a “New Religion.” The 2nd volume of Reichelt’s seminal writings, Fromhetstyper og Helligdommer i Øst-Asia I-III, is an invaluable account of their interactions and discussions on religious topics. Although Luo Miaochi stands as an indispensable figure in the history of Buddhism in Taiwan, research on him remains scarce and limited. This study aims to fill in this gap through a detailed descriptive analysis of the relationship and the communication between Reichelt and Luo, contributing to a better understanding of Miaochi, and of this significant inter-religious dialogue in the historical junction of world religions.

In the process of CVD deposition of SiC, the reaction of carrier gas H2 with the surface of the deposited SiC matrix affects the deposition rate and the quality of the deposited products, so it is of great theoretical and practical significance to study these microscopic reaction mechanisms. The adsorption locations, adsorption energies, electronic structures and coverages of H2 on 3C-SiC (111) (above it is the surface of a silicon atom) and 3C-SiC (111) it is the surface of the carbon atom) planes were studied using the first principles based on density functional theory. The results show that the most stable adsorption position of H atom is the OT position (on top) and belongs to chemical adsorption. Upon adsorption H2 spontaneously dissociates into two H atoms which are adsorbed on two adjacent Si atoms in the form of a double top position, thus the electrons of the Si atoms on the surface of the matrix are shifted to H, where the main interaction between the two stems from the overlapping hybridization of the p-orbital of the Si atom and the s-orbital of H. By calculating the coverage of hydrogen on the surface, it is found that the adsorption energy increases with the increase of the coverage, under the low H coverage rate (θH≤4/9 ML), there is a strong attraction between H atoms, with the increase of H coverage (θH＞4/9 ML), the repulsion force between H atoms gradually increases, the adsorption energy increases slowly, and the overall structure tends to be more stable.
