目的:探讨低级别阑尾黏液性肿瘤腹水脱落细胞的病理形态学特征,结合组织学活检病理特征和临床症状体征,以提高细胞学角度对该病的认识。方法:回顾性分析1例阑尾低级别黏液性肿瘤患者的临床资料、影像学特征、腹水脱落细胞和活检组织学病理形态学特征及预后,并复习国内外相关文献。结果:以腹水为首发症状的阑尾低级别黏液性肿瘤非常罕见,其液基细胞形态主要特点为细胞核通常小而规则,仅有轻度异型性改变,细胞内富含黏液,沉渣包埋制片后可见细胞呈柱状,极向存在,单层或假复层排列,核分裂罕见。本文报道1例以腹水伴盆腔肿物为首发症状就诊,影像学检查与卵巢原发肿瘤鉴别困难,必须结合脱落细胞的病理形态特征进行诊断。结论:阑尾低级别黏液性肿瘤脱落细胞病理形态特点主要为细胞呈柱状,细胞核通常小而规则,异型性小,核分裂罕见,细胞内富含黏液,细胞排列极向存在。腹水伴盆腔肿物极易首诊误诊为原发卵巢肿瘤,同时,通过腹水沉渣细胞学诊断阑尾低级别黏液性肿瘤非常罕见,因此,需结合细胞学形态及临床症状和体征,提高对该病的认识,达到早诊断、早治疗的目的。

Nanogrids are expected to play a significant role in managing the ever-increasing distributed renewable energy sources. If an off-grid nanogrid can supply fullycharged batteries to a battery swapping station(BSS)serving regional electric vehicles(EVs), it will help establish a structure for implementing renewable-energyto-vehicle systems. A capacity planning problem is formulated to determine the optimal sizing of photovoltaic(PV) generation and battery-based energy storage system(BESS) in such a nanogrid. The problem is formulated based on the mixed-integer linear programming(MILP)and then solved by a robust optimization approach. Flexible uncertainty sets are employed to adjust the conservativeness of the robust optimization, and Monte Carlo simulations are carried out to compare the performance of the solutions. Case studies demonstrate the merits of the proposed applications and verify the approach.

The carotenoid-derived volatileβ-ionone makes an important contribution to tea ***,we qualitatively and quantitatively analysed 15 carotenoids in tea leaves of 13 cultivars by UHPLC-APCI-MS/*** 13 cultivars were divided into two groups by PCA(Principal Component Analysis)clustering analysis of their carotenoid content,and OPLS-DA(Orthogonal projections to latent structures)indicated that the levels ofβ-carotene(VIP=2.89)and lutein(VIP=2.30)were responsible for much of the variation between the two ***,theβ-carotene toβ-ionone conversion rates in Group 1 were higher than in Group 2,while theβ-carotene content was significantly lower in Group 1 than in Group ***β-ionone content was significantly higher in Group *** Correlation Coefficient calculation between the transcription level of candidate genes(CsCCD1 and CsCCD4)and the accumulation ofβ-ionone indicated that CsCCD1 may involve in the formation ofβ-ionone in 13 *** expression and in vitro enzyme activity assays showed that‘Chuanhuang 1’had an amino acid mutation in carotenoid cleavage dioxygenases 1(CsCCD1)compared with‘Shuchazao’,resulting in a significantly higherβ-ionone content in‘Chuanhuang 1’.Sequence analysis showed that‘Chuanhuang 1’and‘Huangdan’had different CsCCD1 promoter sequences,leading to significantly higher CsCCD1 expression andβ-ionone accumulation in‘Chuanhuang 1’.These results indicated that the promoter and coding sequence diversity of CsCCD1 might contribute to the differential accumulation ofβ-ionone in different tea cultivars.
