Caspases play important roles in cell apoptosis. Measurement of the dynamics of caspase activation in tumor cells not only facilitates understanding of the molecular mechanisms of apoptosis but also contributes to the development, screening, and evaluation of anticancer drugs that target apoptotic pathways. The fluorescence resonance energy transfer (FRET) technique provides a valuable approach for defining the dynamics of apoptosis with high spatio-temporal resolution. However, FRET generally functions in the single-cell level and becomes ineffective when applied in the high throughput detection of caspase activation. In the current study, a FRET sensor was combined with capillary electrophoresis (CE) to achieve a high throughput method for cellular caspase detection. The FRET-based CE system is composed of a homemade CE system and a laser source for detecting the dynamics of caspase-3 in various cells expressing sensors of caspase-3 that have been treated with anticancer drugs, such as cell cycle-independent drug cisplatin and specific cell cycle drugs camptothecin and etoposide, as well as their combination with tumor necrosis factor (TNF). A positive correlation between the caspase-3 activation velocity and drug concentration was observed when the cells were treated with cisplatin, but cells induced by camptothecin and etoposide did not show any apparent correlation with their concentrations. Moreover, different types of cells presented distinct sensitivities under the same drug treatment, and the combination treatment of TNF and anticancer drugs significantly accelerated the caspase-3 activation process. Its high throughput capability and detection sensitivity make the FRET-based CE system a useful tool for investigating the mechanisms of anticancer drugs and anticancer drug screening.

Objective To investigate the serum levels of semaphorin 3E(Sema3E)in patients with intracranial aneurysms,revealing the correlation between Sema3E and 1-month poor prognosis after interventional embolization.Methods This study was a prospective single-center cohort study,recruiting 102 consecutive patients with intracranial aneurysms who underwent interventional surgery from June 2020 to January 2022 in our hospital.Among them,11 patients were excluded.Clinical and radiological profiles were collected.Peripheral blood was collected after admission,and serum Sema3E levels were determined by enzyme-linked immunosorbent assay.All the aneurysms were treated with endovascular coil embolization or stent-assisted coil embolization.The primary outcome was evaluated with the Glasgow Outcome Scale(GOS)1 month after interventional therapy.The favorable outcome was defined as a GOS score of 4-5,and a poor outcome was defined as a GOS score of 1-3(severe disability,vegetative state,or death).Univariate and multivariate logistic regression analyses were used to identify potential prognostic factors after interventional therapy.Results The average age of 91 patients with intracranial aneurysm was 59.9±11.0 years old,including 70 cases(76.9%)with favorable prognosis and 21 cases(23.1%)with poor prognosis.The mean preoperative Glasgow Coma Scale(GCS)score of the poor prognosis group(9.4±4.5)was significantly lower than that of the favorable prognosis group(13.3±2.5;P<0.001).In the poor prognosis group,the Hunt-Hess grade(3.6±0.6 vs.2.0±1.3,P<0.001)and the serum Sema3E levels[(6.21±1.58)μg/L vs.(4.38±1.77)μg/L,P<0.001]were significantly higher than those in the favorable prognosis group.Logistic regression analysis showed the Hunt-Hess grade(OR =7.150,P =0.003),stent-assisted coil embolization(OR =15.777,P =0.010),and the serum Sema3E level(OR =1.756,P =0.027)were independent prognostic factors for intracranial aneurysms after interventional therapy.Conclusions The serum Sema3E level is closely correlated with the severity of intracranial aneurysms.The serum Sema3E level is a prognostic factor for interventional treatment,which can be used as a biomarker for predicting poor outcomes.

Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is a life support technique for patients with severe respiratory failure. In the past, single lumen cannula was mostly used to constract the vascular pathway of extracorporeal membrane oxygenation. Compared with single-lumen cannula, double lumen cannula (DLC) can reduce recirculation fraction, reduce complications such as infection and bleeding, and facilitate patient's rehabilitation. DLC requires accurate positioning of the catheter. It has been gradually applied in China. This paper will review the key points related to the use of DLC, such as the insertion, position, and complications, etc. to provide guidance for clinical application practice.
