目的调查1例不明原因导致多器官受损的中毒的原因,确证致病因子种类和暴露量,查明致病因子来源,为患者临床救治以及此类事件预防提供参考和依据。方法从患者长期服用的不明中药入手,首先用靶向策略进行筛查,考察是否为生物碱中毒,然后采用非靶向策略信息依赖采集模式(IDA)筛查患者血液、尿液和药物,结合可疑化合物的毒理作用和患者临床表现,确定致病因子。根据标准品建立定量方法,对全部样品中致病因子进行定量检测。流行病学调查获得患者服药史,结合药物规格及含量检测结果,确定各致病因子暴露量。最后采用数据非依赖序列窗口采集模式(SWATH)筛查全部样品,无偏采集化合物二级质谱信息,对已确证的致病因子进行验证和补充。结果靶向筛查排除常见生物碱中毒。患者血液、尿液均筛查出他达拉非,不明中成药检出他达拉非、西地那非、他达拉非甲基氯化物、扑热息痛和双氯芬酸,上述化合物副作用与患者临床表现相符。他达拉非、西地那非、他达拉非甲基氯化物、双氯芬酸和扑热息痛的长期日均暴露剂量最高分别为30.5、15.8、0.05、45.6和3.2 mg,严重过量。序列窗口采集模式同样筛查出上述5种药物,并检出盐酸巴马汀。结论本研究综合采用靶向筛查、非靶向筛查和靶向定量策略、数据依赖和数据非依赖采集模式,结合患者临床表现与流行病学资料,确定本例是由长期过量服用添加化学成分的中成药引起的药物中毒。本研究可为临床不明原因中毒患者诊断和调查提供思路,为相关中毒事件的应急检测和处置提供参考。

目的评估天冬氨酸转氨酶与血小板比值指数(APRI)和血小板-白蛋白-胆红素评分(PALBI)对肝硬化并发食管胃底静脉曲张破裂出血风险的预测价值。方法选取苏州大学附属第一医院于2021年5月—2022年6月收治的肝硬化患者119例,收集患者的临床资料、血常规、血清生化及血凝等检查结果。根据是否合并食管胃底静脉曲张破裂出血,将患者分为未出血组(n=59)和出血组(n=60),比较组间差异。正态分布的计量资料两组间比较采用独立样本t检验,非正态分布的计量资料两组间比较采用Mann-Whitney U检验。计数资料组间比较采用χ^(2)检验或Fisher精确概率法。使用多因素Logistic回归分析,筛选肝硬化并发食管胃底静脉曲张破裂出血的独立危险因素,并构建列线图预测模型。结果出血组男性患者占75.00%,未出血组男性患者占40.68%,两组在性别构成方面,差异具有统计学意义(χ^(2)=14.384,P<0.001)。出血组和未出血组患者病因均以慢性乙型肝炎为主(53.33%vs 38.98%),两者构成比差异无统计学意义(χ^(2)=2.464,P=0.116)。出血组患者抗凝血酶原Ⅲ活性(AT-IIIA)水平高于未出血组(t=3.329,P=0.001),PLT、TBil、Ca、TC、TT水平则低于未出血组(P值均<0.05)。APRI和PALBI在出血组和未出血组之间比较,差异均有统计学意义(χ^(2)值分别为6.175、19.532,P值均<0.05)。进一步二元Logistic回归分析发现,APRI(OR=0.309,95%CI:0.109~0.881,P=0.028)、PALBI(OR=7.667,95%CI:2.005~29.327,P=0.003)、Ca(OR=0.001,95%CI:0.000~0.141,P=0.007)、TC(OR=0.469,95%CI:0.226~0.973,P=0.042)和TT(OR=0.599,95%CI:0.433~0.830,P=0.002)是影响肝硬化并发食管胃底静脉曲张破裂出血的独立影响因素。基于以上因素建立列线图模型,一致性指数(C-index)为0.899,校准曲线拟合良好。结论 APRI及PALBI对肝硬化并发食管胃底静脉曲张破裂出血具有良好的预测价值,基于本研究构建的列线图模型可以个体化预测肝硬化患者食管胃底静脉曲张破裂出血发生率。

Mutation in the gene encoding 1-aminocyclopropane-1-carboxylate synthase 4 (CitACS4) led to andromonoecy in watermelon

Summary Although it has been reported previously that ethylene plays a critical role in sex determination in cucurbit species, how the andromonoecy that carries both the male and hermaphroditic flowers is determined in watermelon is still unknown. Here we showed that the watermelon gene 1-aminocyclopropane-1-carboxylate syn- thase 4 CCitACS4）, expressed specifically in carpel primor- dia, determines the andromonoecy in watermelon. Among four single nucleotide polymorphism （SNPs） and one lnDel identified in the coding region of CitACS4, the C364W mutation located in the conserved box 6 was co- segregated with andromonoecy. Enzymatic analyses showed that the C364W mutation caused a reduced activity in CitACS4. We believe that the reduced CitACS4 activity may hamper the programmed cell death in stamen primordia, leading to the formation of hermaphroditic flowers.

Aurora-A is a novel predictor of poor prognosis in patients with resected lung adenocarcinoma

引用

Chinese Journal of Cancer Research 2014年第2期26卷 166-173页

作者： Bo Zeng Yiyan Lei Haoshuai Zhu Shenyuan Luo Mei Zhuang Chunhua Su Jianyong Zou Lei Yang honghe Luo Department of Thoracic Surgery The First Affiliated Hospital Sun Yat-sen University Private Medical Center The First Affiliated Hospital Sun Yat-sen University

Background： The Aurora-A （AurA） gene, a key regulator of mitosis, has been proved as an oncogene in a variety of cancers. The Aur-A overexpression has been proved correlated with aggressiveness of cancer cells. However, the frequency of Aur-A protein overexpression, as well as its association with clinicopathologic parameters and prognosis remain unclear in lung adenocarcinoma （ADC）. This study tried to clarify the clinical significance of Aur-A in patients with resected lung ADC. Patients and methods： A total of 142 informative patients with surgically resected lung ADC and 20 normal lung tissues were enrolled. Western blot and immunohistochemistry （IHC） were utilized to assess protein expression of Aur-A. Result： The expression of Aur-A was elevated in most of tumor tissues compared with the adjacent tissues by western blot. The IHC results showed that Aur-A protein was over-expressed in 98 of 142 （69.0%） tumor sections, while Aur-A was low-expressed in all normal lung sections. A positive correlation between Aur-A overexpression rate and ascending pathologic stages was observed （P〈0.05）. Kaplan-Meier analysis demonstrated that patients with Aur-A high expression had significantly inferior survival compared to those with Aur-A low expression. Both overall survival （OS） and disease-free survival （DFS） of positive overexpression patients were shorter than the negative group （P=0.036, P=0.041, respectively）. Multivariate analysis confirmed that Aur-A expression, as an independent and significant factor for both DFS and OS, could predict a poor prognosis in patients with resected lung ADC （P=0.022, P=0.049, respectively）. Conclusions： Aur-A was overexpressed in lung ADC and overexpression of Aur-A might be a novel predictor for poor prognosis and potential therapeutic target in lung ADC.
