BACKGROUND Aortic dissection during pregnancy is a rare but life-threatening event for mothers and fetuses. It often occurs in the third trimester of pregnancy and the postpartum period. Most patients have connective tissue diseases such as Marfan syndrome. Thus, the successful repair of a sporadic aortic dissection with maternal and fetal survival in the early second trimester is extremely rare. CASE SUMMARY A 28-year-old woman without Marfan syndrome presented with chest pain at the 16th gestational week. Aortic computed tomographic angiography confirmed an acute type A aortic dissection (TAAD) with aortic arch and descending aorta involvement. Preoperative fetal ultrasound confirmed that the fetus was stable in the uterus. The patient underwent total arch replacement with a frozen elephant trunk using moderate hypothermic circulatory arrest with the fetus in situ. The patient recovered uneventfully and continued to be pregnant after discharge. At the 38^th gestational week, she delivered a healthy female infant by cesarean section. After 2.5 years of follow-up, the patient is uneventful and the child’s development is normal. CONCLUSION A fetus in the second trimester may have a high possibility of survival and healthy growth after aortic arch surgery.

BACKGROUND Postoperative acute kidney injury(AKI) is a major complication associated with increased morbidity and mortality after surgery for acute type A aortic dissection(AAAD). To the best of our knowledge, risk prediction models for AKI following AAAD surgery have not been reported. The goal of the present study was to develop a prediction model to predict severe AKI after AAAD *** A total of 485 patients who underwent AAAD surgery were enrolled and randomly divided into the training cohort(70%) and the validation cohort(30%). Severe AKI was defined as AKI stage Ⅲ following the Kidney Disease: Improving Global Outcomes criteria. Preoperative variables, intraoperative variables and postoperative data were collected for analysis. Multivariable logistic regression analysis was performed to select predictors and develop a nomogram in the study cohort. The final prediction model was validated using the bootstrapping techniques and in the validation *** The incidence of severe AKI was 23.0%(n = 78), and 14.7%(n = 50) of patients needed renal replacement *** hospital mortality rate was 8.3%(n = 28), while for AKI patients, the mortality rate was 13.1%, which increased to 20.5% for severe AKI patients. Univariate and multivariate analyses showed that age, cardiopulmonary bypass time, serum creatinine, and D-dimer were key predictors for severe AKI following AAAD surgery. The logistic regression model incorporated these predictors to develop a nomogram for predicting severe AKI after AAAD surgery. The nomogram showed optimal discrimination ability, with an area under the curve of 0.716 in the training cohort and 0.739 in the validation cohort. Calibration curve analysis demonstrated good correlations in both the training cohort and the validation *** We developed a prognostic model including age, cardiopulmonary bypass time, serum creatinine, and D-dimer to predict severe AKI after AAAD surgery. The prognostic model demonst

To the Editor:For patients with acute DeBakey type laortic dissection,ascending aortic or hemiarch replacement can reduce the surgical time and save lives in critical ***,residual distal dissection increases the risk of dilatation,rupture,and death.[1] In contrast,total aortic arch replacement(TAR)with frozen elephant trunk(FET)implantation can minimize the need for re-intervention,[2] but may increase the risk of operative mortality,stroke,paraplegia,and other ***,the ques-tion of the optimal surgical strategy for acute DeBakey type I aortic dissection remains controversial owing to the scarcity of long-term follow-up data and the technical diversities among different institutions.

19世纪英国经历了4次比较严重的霍乱疫情,其中仅伦敦就有3.7万人因此丧生。这种新型瘟疫对英国社会提出了挑战。英国人对霍乱传播途径,先认定是人际传播,后来坚信瘴气理论,不同意斯诺的水传播看法。英国人依靠议会立法手段,通过法律,建立相关组织,授权采取措施。从30年代的"隔离"隔绝健康人与患者,到40—50年代的"大清扫""大清洁"清除垃圾,建设下水道,排除污水,规范管道水,歪打正着地阻断了霍乱弧菌传播的渠道。由此可见,英国的霍乱疫情在一定程度上推动了给排水基础设施的现代化建设。

Pyridyl-based ketones and 1,6-diketones are both attractive and invaluable scaffolds which play pivotal roles in the construction and structural modification of a plethora of synthetically paramount natural products, pharmaceuticals, organic materials and fine chemicals. In this context, we herein demonstrate an unprecedented, robust and generally applicable synthetically strategy to deliver these two crucial ketone frameworks via visible-light-induced ring-opening coupling reactions of cycloalcohols with vinylazaarenes and enones, respectively. A plausible mechanism involves the selective β-C-C bond cleavage of cycloalcohols enabled by proton-coupled electron transfer and ensuing Giese-type addition followed by single electron reduction and protonation. The synthetic methodology exhibits broad substrate scope,excellent functional group compatibility as well as operational simplicity and environmental friendliness.
