| 1 | Intraductal neoplasm of the intrahepatic bile duct: Clinicopathological study of 24 cases显示文摘AIM: To investigate the clinicopathological features of intraductal neoplasm of the intrahepatic bile duct (INihB). METHODS: Clinicopathological features of 24 cases of INihB, which were previously diagnosed as biliary papillomatosis or intraductal growth of intrahepatic biliary neoplasm, were reviewed. Mucin immunohistochemistry was performed for mucin (MUC)1, MUC2, MUC5AC and MUC6. Ki-67, P53 and β-catenin immunoreactivity were also examined. We categorized each tumor as adenoma (low grade), borderline (intermediate grade), and malignant (carcinoma in situ , high grade including tumors with microinvasion). RESULTS: Among 24 cases of INihB, we identified 24 tumors. Twenty of 24 tumors (83%) were composed of a papillary structure; the same feature observed in intraductal papillary neoplasm of the bile duct (IPNB). In contrast, the remaining four tumors (17%) showed both tubular and papillary structures. In three of the four tumors (75%), macroscopic mucin secretion was limited but microscopic intracellular mucin was evident. Histologically, 16 tumors (67%) were malignant, three (12%) were borderline, and five (21%) were adenoma. Microinvasion was found in four cases (17%). Immunohistochemical analysis revealed that MUC1 was not expressed in the borderline/adenoma group but was expressed only in malignant lesions (P = 0.0095). Ki-67 labeling index (LI) was significantly higher in the malignant group than in the borderline/adenoma group (22.2 ± 15.5 vs 7.5 ± 6.3, P < 0.01). In the 16 malignant cases, expression of MUC5AC showed borderline significant association with high Ki-67 LI (P = 0.0622). Nuclear expression of β-catenin was observed in two (8%) of the 24 tumors, and these two tumors also showed MUC1 expression. P53 was negative in all tumors. CONCLUSION: Some cases of INihB have a tubular structure, and are subcategorized as IPNB with tubular structure. MUC1 expression in INihB correlates positively with degree of malignancy. | Yoshiki Naito Hironori Kusano Osamu Nakashima Eiji Sadashima Satoshi Hattori Tomoki Taira Akihiko Kawahara Yoshinobu Okabe Kazuhide Shimamatsu Jun Taguchi Seiya Momosaki Koji Irie Rin Yamaguchi Hiroshi Yokomizo Michiko Nagamine Seiji Fukuda Shinichi Sugiyama Naoyo Nishida Koichi Higaki Munehiro Yoshitomi Masafumi Yasunaga Koji Okuda Hisafumi Kinoshita Masayoshi Kage Masamichi Nakayama Makiko Yasumoto Jun Akiba Hirohisa Yano | 2012 | World Journal of Gastroenterology2012，18，28： | 16 |
| 2 | 小胶质细胞可能通过选择性吞噬丘脑底核谷氨酸能突触来代偿多巴胺能神经元丢失造成的帕金森模型鼠的功能缺失显示文摘当帕金森患者出现临床症状时,其黑质致密部的绝大部分多巴胺神经元已发生退行性改变。这提示可能存在某些代偿机制,延缓了临床症状的出现。本研究制作6-羟多巴胺诱导的偏侧帕金森大鼠模型,观察位于黑质下网状部和苍白球的激活的小胶质细胞在代偿机制中的作用。研究发现,在偏侧帕金森大鼠中,黑质下网状部聚集的激活的小胶质细胞远多于苍白球中。激活的小胶质细胞胞体增大并表达吞噬物标志物CD68和NG2蛋白多糖。激活的小胶质细胞聚集在黑质下网状部的特定部位,该部位的突触蛋白I和突触后密集蛋白95的表达降低。活化的小胶质细胞吞噬突触前、后膜上的各种蛋白,包括NMDA受体。将红色荧光标记物Di I作为顺行示踪剂注入丘脑底核,可见黑质下网状部和苍白球内的细胞吞噬了Di I。在谷氨酸刺激下,原代培养的小胶质细胞吞噬活动增强,编码吞噬相关因子的m RNA转录水平也增加。人工合成的糖皮质激素地塞米松可以减弱这种改变。给PD大鼠皮下注射地塞米松,可以抑制黑质下网状部小胶质细胞的活化,运动功能障碍进一步加重,谷氨酸能突触转录m RNA增加,GABA能突触转录m RNA水平未增加。这些发现提示,当谷氨酸能神经元活动增强时,黑质下网状部和苍白球的小胶质细胞活化,选择性吞噬丘脑底核的谷氨酸能突触。因此,在基底核区可能存在一个负反馈环路,间接地代偿了由于多巴胺能神经元丢失而导致的功能障碍。小胶质细胞在这个负反馈环路中扮演了重要的角色。 | Aono H Choudhury ME Higaki H Miyanishi K Kigami Y Fujita K Akiyama JI Takahashi H Yano H Kubo M Nishikawa N Nomoto M Tanaka J 唐颖馨 | 2017 | 神经损伤与功能重建2017，12，5： | 7 |
| 3 | Impact of time from diagnosis to chemotherapy in advanced gastric cancer: A Propensity Score Matching Study to Balance Prognostic Factors显示文摘BACKGROUND It is unclear whether treatment delay affects the clinical outcomes of chemotherapy in advanced gastric cancer(A-GC).AIM To assess whether treatment delay affects the clinical outcomes of chemotherapy in A-GC.METHODS This single-center retrospective study examined consecutive patients with A-GC between April 2012 and July 2018. In total, 110 patients with stage Ⅳ A-GC who underwent chemotherapy were enrolled. We defined the wait time(WT) as the interval between diagnosis and chemotherapy initiation. We evaluated the influence of WT on overall survival(OS).RESULTS The mean OS was 303 d. The median WT was 17 d. We divided the patients into early and elective WT groups, with a 2-wk cutoff point. There were 46 and 64 patients in the early and elective WT groups, respectively. Compared with the elective WT group, the early WT group had significantly lower albumin(Alb)levels and higher neutrophil/lymphocyte ratios and C-reactive protein(CRP)levels but not a lower performance status. The elective WT group underwent more combination chemotherapy than did the early WT group. OS was different between the two groups(230 d vs 340 d, respectively). Multivariate analysis revealed that higher CRP levels, lower Alb levels and monotherapy were significantly related to a poor prognosis. To minimize potential selection bias,patients in the elective WT group were 1:1 propensity score matched with patients in the early WT group; no significant difference in OS was found(303 d vs 311 d, respectively, log-rank P = 0.9832).CONCLUSION A longer WT in patients with A-GC does not appear to be associated with a worse prognosis. | Tsutomu Nishida Aya Sugimoto Ryo Tomita Yu Higaki Naoto Osugi Kei Takahashi Kaori Mukai Tokuhiro Matsubara Dai Nakamatsu Shiro Hayashi Masashi Yamamoto Sachiko Nakajima Koji Fukui Masami Inada | 2019 | World Journal of Gastrointestinal Oncology2019，11，1： | 4 |
| 4 | ICRF Heated Long-Pulse Plasma Discharges in LHD显示文摘A long-pulse plasma discharge for more than 30 min.was achieved on the LargeHelical Device(LHD).A plasma of n_e=0.8×10^(19)m^(-3)and T_(iO)=2.0 keV was sustained withP_(ICH)=0.52 MW,P_(ECH)=0.1 MW and averaged P_(NBI)=0.067 MW.Total injected heatingenergy was 1.3 GJ,which was a quarter of the prepared RF heating energy.One of the keys to thesuccess of the experiment was a dispersion of the local plasma heat load to divertors,accomplishedby shifting the magnetic axis inward and outward. | R.

| 5 | Regulation of Root-Knot Nematode Behavior by Seed-Coat Mucilage-Derived Attractants显示文摘Seed exudates influence the behavior of soil organisms,but howthis occurs remains unclear,particularly for multicellular animals.Here we show that compounds associated with Arabidopsis seed-coat mucilage regulate the behavior of soil-borne animals,specifically root-knot nematodes (RKNs).Infective RKN J2 larvae actively travel toward Arabidopsis seeds through chemotaxis.Analysis of Arabidopsis mucilage mutants demonstrated that the attraction of RKNs toArabidopsis seeds requires the synthesis and extrusion of.seed-coat mucilage.Extracted mucilage alone is not sufficient to attract RKNs,but seed-surface carbohydrates and proteins are required for this process.These findings suggest that the RKN chemoattractant is synthesized de novo upon mucilage extrusion but may be highly unstable.RKNs attracted by thismucilage-dependent mechanism can infect the emerging seedling.However,the attraction signal from seedling roots likely acts independently of the seed-coat signal and may mask the attraction to seed-coat mucilage after germination.Multiple RKN species are attracted byArabidopsis seeds,suggesting that this mechanism is conserved in RKNs.These findings indicate that seed exudate can regulate the behavior of multicellular animals and highlight the potential roles of seed-coat mucilage in biotic interactions with soil microorganisms. | Allen Yi-Lun Tsai Takumi Higaki Chinh-Nghia Nguyen Laetitia Perfus-Barbeoch Bruno Favery Shinichiro Sawa | 2019 | Molecular Plant2019，12，1： | 3 |
