2涎腺肌上皮癌:一种具有挑战性和诊断陷阱及潜在意义的肿瘤实体显示文摘肌上皮癌是一种尚未被充分认识的具有宽泛形态学谱系的肿瘤实体,因与其他肿瘤相似,尤其是与富于肌上皮细胞的多形性腺瘤较难鉴别。作者报道21例组织学上具有挑战性的肌上皮癌(16例起源于多形性腺瘤的肌上皮癌,5例为肌上皮癌)。16例多形性腺瘤的肌上皮癌中除3例外,其余均有包膜内或最低限度的浸润。21例肌上皮癌中18例(86%)最初被误诊为良性肿瘤,包括多形性腺瘤(10例)、不典型多形性腺瘤(5例)和肌上皮瘤(3例);另3例最初被诊断为恶性肿瘤(起源于多形性腺瘤的肌上皮癌)。Xu B Mneimneh W Torrence D E 魏建国(摘译) 袁晓露(审校) 2019临床与实验病理学杂志2019,35,10:6
3Insecticide toxicity associated with detoxification enzymes and genes related to transcription of cuticular melanization among color morphs of Asian citrus psyllid显示文摘The Asian citrus psyllid (Diaphorina citri Kuwayama) is known to exhibit abdominal color polymorphisms. In the current study, susceptibility to four insecticides was compared among orange/yellow, blue/green and gray/brown color morphs of field collected D. citri. The LD50 values and 95% fiducial limits were quantified for each insecticide and color morph combination and ranged between 0.10 ng/μL (0.06-0.10) and 6.16 ng//μL (3.30-12.50). Second, we measured the detoxification enzyme activity levels of orange/yellow, blue/green and gray/brown color morphs for cytochrome P450, glutathione 'S-transferase, and general esterase. The mean P450 activity (equivalent units) was significantly lower in gray/brown (0.152 ± 0.006) and blue/green morphs (0.149 ± 0.005) than in the orange/yellow morphs (0.179 ± 0.008). GST activity (/imol/min/mg protein) was significantly lower in the orange/yellow morph (299.70 ± 1.24) than gray/brown (350.86 ± 1.19) and blue/green (412.25 ±1.37) morphs. The mean EST activity (/xmol/min/mg protein) was significantly higher in blue/green (416.72±5.12) and gray/brown morphs (362.19 ± 4.69) than in the orange/yellow morphs (282.56 ± 2.93). Additionally, we analyzed the relative expression of assortment genes involved in cuticular melanization and basal immunity. The transcripts of Dopa Decarboxylase and Tyrosine Hydroxylase were expressed higher in blue/green and gray/brown than orange/yellow morphs. The transcription results paralleled the susceptibility of D.citri to organophosphate, neonicotinoid and pyrethroid insecticides. GST and EST activity may also be correlated with low levels of insecticide susceptibility. Cuticular melanization could be a factor for the development of resistance to insecticides among different color morphs.Xue Dong Chen Torrence A.
