05). The mean emergence agitation score in group B was significantly lower than that in group A when the maximum emergence in group B was at 20 min after entering into PACU (p  less then  0.05). In conclusion, etomidate combined with fentanyl plays a good efficacy in anesthesia of pediatric strabotomy compared with etomidate plus ketamine. The human papillomavirus (HPV) is one of the main sexually transmitted pathogens that infect the anogenital epithelium and mucous membranes. HPV genotypes can be classified as high and low oncogenic risk, with infection by the former resulting in cervical cancer in approximately 100 % of the cases. In this work, we developed an ultrasensitive electrochemical biosensor for the detection and identification of different HPV genotypes. A nanostructured platform based on a matrix of polyaniline (PANI) containing gold nanoparticles (AuNps) was designed for the chemical immobilization of a DNA probe capable of recognizing different HPV types. Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and atomic force microscopy (AFM) were used to characterize the genosensor. The impedimetric responses indicate that the proposed sensor was able to detect HPV (types 6, 11, 16, 31, 33, 45, and 58) in cervical specimens (cDNA samples). We obtained different profiles of electrochemical responses for the high and low-risk HPV genotypes. By adopting a three-dimensional quantitative analysis of impedance response variables, it was possible to identify the existence of a pattern of association for samples of high oncogenic risk, which may lead to the differential diagnosis of HPV. The biosensor demonstrated an excellent analytical performance for the detection of HPV genotypes with high sensibility and selectivity. The genosensor exhibited a linear range of response in the 1 pg μL-1 to 100 pg μL-1 range. Besides, a limit of detection (LOD) of 2.74 pg μL-1 and 7.43 pg μL-1 was obtained for HPV11 and HPV16, respectively, with regression coefficients of 99.88 % and 99.47 %. Thus, the proposed sensor may serve as a good prognostic indicator for patients infected with papillomavirus. Powdered Poppy Capsule Extractive (PPCE) is largely used as a raw material of Compound Liquorice Tablets, but there are few studies of its quality evaluation or control. In this paper, a novel strategy for quality assessment of PPCE, systematic quantified fingerprint method (SQFM) combined with quantitative analysis of multi-components by a single marker (QAMS) method, was developed and validated. According to the outcome of Pm and the content of codeine and morphine, 41 batches of PPCEs were classified into two classifications by hierarchical cluster analysis, and the samples in one of the categories were obviously inferior to normal in quality. The results demonstrated that the strategy developed in this paper could provide a new method for quality evaluation of PPCE or even other traditional Chinese medicine (TCM). Currently, controllable linker cleavage at the target site will facilitate the clinical treatment of cancer. Dual-functional prodrugs in combination of carbohydrate as targeting group and pH-sensitive cleavable linker are desired in clinical development. Here, a qualified structure of N-phenylcarbamate-d-gluconhydroximo-1,5-lactam was employed and proved to be a potential candidate prodrug in the drug design. To proof this concept, the possible mechanism of Beckmann rearrangement and the degraded products were confirmed by HPLC and LC-MS under the acid condition mimic lysosome. Hence, the strategy of d-gluconhydroximo-1,5-lactam as a prodrug carrier fabricated with interested drugs will provide a great potential approach for chemotherapy. Charge variant profiling of therapeutic proteins is required by the International Council for Harmonisation guidelines and is traditionally performed by capillary electrophoresis or ion exchange chromatography. Recently, improvements in the hyphenation of capillary electrophoresis with mass spectrometry and the introduction of mass spectrometry compatible background electrolytes has allowed the implementation of native mass spectrometric determination of the charge variant profile obtained from the electrophoretic separation. The low flow operation of the microfluidic electrophoretic platform significantly boosts mass spectrometric sensitivity and increases the dynamic range, even when using sample amounts as low as 1 ng in capillary. In the current study, rituximab, trastuzumab and bevacizumab drug products were analysed using the ZipChip microfluidic CE-ESI-MS platform that facilitated confident identification of proteoforms with an average mass accuracy of less then 15 ppm. Up to 52 proteoforms were identified for trastuzumab drug product, while rituximab sample revealed the presence of fragments and sialylated N-glycans. Overall, the CE-ESI-MS platform proved to be a fast and robust tool for therapeutic protein charge variant profiling and facilitated efficient coupling with native mass spectrometry for the generation of highly informative characterisation data. Immunogenicity related to the degradation of therapeutic monoclonal antibodies (mAbs) remains a major concern for their therapeutic efficacy and safety. Therefore, an analytical method allowing characterization and detection of mAbs degradation is mandatory. In this study, a simultaneous coupling of size exclusion chromatography (SEC) to native mass spectrometry (MS) and fluorescence detection (FLD) is proposed to detect degraded therapeutic mAbs and biases of structural changes (e.g. dimerization, denaturation) that may occur during native MS. A comprehensive study on infliximab behaviors have been performed under different mobile phase conditions (e.g. composition, pH, organic solvent, etc.) and MS parameters (e.g. gas temperatures, CID energies, etc.). Experimental conditions avoiding artificial denaturation and/ or dimerization have been defined. We have also demonstrated that under the developed conditions infliximab affinity towards its biological target TNFα is preserved. In addition, using this method dimers, denatured monomers and fragments could be detected in trastuzmab samples stressed by a long-term storage. These results were confirmed by using SEC coupled to ion mobility mass spectrometry as an orthogonal method for the detection of denatured monomer. Ulcerative colitis (UC) is characterized by a relapsing and remitting pattern. The remission phase may last weeks to years. It remains unclear what specific factors can cause the disease to exist the remission phase and enter an activated state. IL-10 is a cytokine best known for its anti-inflammatory roles. We hypothesized that IL-10 might have a role in suppressing disease flares in UC remission patients. Unexpectedly, we found that UC remission patients with higher serum IL-10 levels presented faster progression to disease flares. Subsequently, we found that exogenous IL-10 could significantly reduce the level of CD4 and CD8 T cell proliferation. On the other hand, IL-10 significantly elevated the viability of activated CD4 and CD8 T cells. Interestingly, it appeared that the IL-10-mediated pro-survival effects were more pronounced in CD8 T cells than in CD4 T cells and were able to promote the survival of activated T cells when administered prior to cell activation. To examine whether IL-10 in the serum of UC patients was able to enhance T cell survival, we separated UC remission patients into Low, Intermediate, and High groups based on the serum IL-10 level. The native serum from High IL-10 patients, but not the native serum from Low IL-10 patients, could significantly increase the viability of activated T cells. In conclusion, we demonstrated that high IL-10 level at the remission phase was associated with shorter duration of remission, possibly due to IL-10-mediated effects on T cell survival. PURPOSE To report CT features of coronavirus disease-2019 (COVID-19) in patients with various disease severity. METHODS The CT manifestations and clinical data of 73 patients with COVID-19 were retrospectively collected in 6 hospitals from Jan 21 to Feb 3, 2020. We analyzed the initial and follow-up CT features of patients with disease severity, according to the Guidelines for the Diagnosis and Treatment of New Coronavirus Pneumonia. RESULTS Six patients (8%) were diagnosed as mild type pneumonia; these patients had no obvious abnormal CT findings or manifested mild changes of lung infection. All 43 patients (59 %) with common type presented unique or multiple ground-glass opacities (GGO) in the periphery of the lungs, with or without interlobular septal thickening. In the 21 patients (29 %) with severe type, extensive GGO and pulmonary consolidation were found in 16 cases (16/21, 76 %) and 5 cases (24 %), respectively. click here An extensive "white lung", with atelectasis and pleural effusion were found in critical type patients (3, 4%). On the resolutive phase of the disease, CT abnormalities showed complete resolution, or demonstrated residual linear opacities. CONCLUSIONS Different CT features are seen according to disease severity, which can help COVID-19 stratification. PURPOSE To evaluate a deep learning based image analysis software for the detection and localization of distal radius fractures. METHOD A deep learning system (DLS) was trained on 524 wrist radiographs (166 showing fractures). Performance was tested on internal (100 radiographs, 42 showing fractures) and external test sets (200 radiographs, 100 showing fractures). Single and combined views of the radiographs were shown to DLS and three readers. Readers were asked to indicate fracture location with regions of interest (ROI). The DLS yielded scores (range 0-1) and a heatmap. Detection performance was expressed as AUC, sensitivity and specificity at the optimal threshold and compared to radiologists' performance. Heatmaps were compared to radiologists' ROIs. RESULTS The DLS showed excellent performance on the internal test set (AUC 0.93 (95% confidence interval (CI) 0.82-0.98) - 0.96 (0.87-1.00), sensitivity 0.81 (0.58-0.95) - 0.90 (0.70-0.99), specificity 0.86 (0.68-0.96) - 1.0 (0.88-1.0)). DLS performance decreased on the external test set (AUC 0.80 (0.71-0.88) - 0.89 (0.81-0.94), sensitivity 0.64 (0.49-0.77) - 0.92 (0.81-0.98), specificity 0.60 (0.45-0.74) - 0.90 (0.78-0.97)). Radiologists' performance was comparable on internal data (sensitivity 0.71 (0.48-0.89) - 0.95 (0.76-1.0), specificity 0.52 (0.32-0.71) - 0.97 (0.82-1.0)) and better on external data (sensitivity 0.88 (0.76-0.96) - 0.98 (0.89-1.0), specificities 0.66 (0.51-0.79) - 1.0 (0.93-1.0), p  less then  0.05). In over 90%, the areas of peak activation aligned with radiologists' annotations. CONCLUSIONS The DLS was able to detect and localize wrist fractures with a performance comparable to radiologists, using only a small dataset for training. PURPOSE T2-FLAIR mismatch sign was reported as specific imaging marker in non-enhancing diffuse astrocytoma, IDH-mutant & 1p/19q non-codeleted. However, most of the previous studies for T2-FLAIR mismatch sign were confirmed only among lower grade glioma. The aim of this study is to assess the T2-FLAIR mismatch sign in dysembryoplastic neuroepithelial tumor (DNET) and unveil the exception rules of the sign. METHOD Eleven patients with histopathologically confirmed DNET were included in this study. The MR images were evaluated by 2 independent reviewers to assess (i) the presence or absence of T2-FLAIR mismatch sign and (ii) the presence or absence of gadolinium enhancement. CT was also performed to evaluate calcification and localized thinning of the skull bone. Inter-reviewer agreement with Cohen's kappa (κ) was calculated. RESULTS The T2-FLAIR mismatch sign was present in 8 cases (72.7 %) and absent in 3 cases (27.3 %). None of them showed contrast enhancement on initial MR images. The inter-reviewer agreement for T2-FLAIR mismatch and CT characteristics was excellent (κ = 1.
