Abstract
Immobilized enzymes exhibit favorable advantages in biocatalysis, such as high operation stability, feasible reusability, and improved organic solvents tolerance. Herein, an immobilized ω-amine transaminase AtATA@MWCNTs-NH2 is successfully prepared using amino modified multi-walled carbon nanotubes as carrier and glutaraldehyde as crosslinker. Under the optimum immobilization conditions, the activity recovery is 78.7%. Compared with purified enzyme AtATA, AtATA@MWCNTs-NH2 possesses superior stability, even in harsh conditions (e.g., high temperature, acidic or alkali environment, and different kind of organic solvents). To simplify the separation and extraction of products, we choose methanol (10%, v/v) as the cosolvent, replacing DMSO (20%, v/v) in our previous work, for the catalytic reaction of AtATA@MWCNTs-NH2. AtATA@MWCNTs-NH2 can be used for stereoselective synthesis (R)-(+)- 1(1-naphthyl)ethylamine ((R)-NEA) for 15 cycles, with the e.e.p (enantiomeric excess) > 99.5%. The catalytic process of AtATA@MWCNTs-NH2 achieves cycle production of (R)-NEA using methanol as cosolvent.

Abstract
Objective: To compare the prevalence of frailty and related factors in middle-aged and elderly people aged ≥45 years in island and mountainous areas of Taizhou, Zhejiang Province. Methods: Based on cross-sectional design, stratified cluster sampling and quota sampling methods were adopted. One administrative district was randomly selected from each of six coastal and three inland administrative districts in Taizhou during July to August, representing two different geographical terrains. In the island area (Jiaojiang District), all residents aged ≥45 years were included by cluster sampling. In the mountainous area (Xianju County), participants were selected through quota sampling, with same gender and age distributions. Data about their demographic characteristics, lifestyle and health-related factors were collected through questionnaire surveys and laboratory examinations. The prevalence of frailty was assessed using the Fried frailty phenotype scale. Hierarchical analysis and multivariate logistic regression analysis were used to compare the influencing factors of frailty. Results: A total of 1 011 local residents were studied, in whom island and mountainous residents accounted for 48.1% (486/1 011) and 51.9% (525/1 011) respectively; men and women accounted for 45.9% (464/1 011) and 54.1% (547/1 011) respectively. Middle-aged (45-49 years), younger elderly (60-74 years), and older elderly (≥75 years) residents accounted for 38.6% (390/1 011), 44.6% (451/1 011), and 16.8% (170/1 011) respectively. The overall prevalence rate of frailty was 3.6% (36/1 011), the prevalence rate was 3.7% (17/464) in men and 3.5% (19/547) in women. The prevalence rates in age groups 45-59,60-74 years and ≥75 years were 0.3% (1/390), 2.2% (10/451), and 14.7% (25/170), respectively. The prevalence rates of frailty and pre-frailty in island area were 6.0% (29/486) and 39.1% (190/486), respectively, which was higher than those in mountainous area (1.3%, 7/525) and (30.9%, 162/525). After adjusting for potential confounding factors, the risk for frailty in island residents was significantly higher than that in mountainous residents (aOR=1.55,95%CI: 1.07-2.25,P=0.019). In island area, older age (60-74 years:aOR=2.52,95%CI: 1.56-4.13; ≥75 years:aOR=11.65,95%CI:5.38-26.70), being women (aOR=1.94,95%CI: 1.20-3.17), suffering from depression (aOR=1.09,95%CI:1.02-1.17) were associated with frailty symptoms. In mountainous area, older age was also associated with an increased risk of frailty symptoms, but the OR value was lower than those in island area (60-74 years: aOR=1.74,95%CI:1.04-2.94;≥75 years: aOR=4.78,95%CI:2.45-9.50). Polydrug use (aOR=2.08,95%CI: 1.14-3.80) and suffering from depression (aOR=1.10,95%CI: 1.02-1.18) had significant positive association with frailty symptoms. Higher education level had significant negative association with frailty symptoms (junior high school: aOR=0.40,95%CI: 0.21-0.75; senior high school and technical secondary school: aOR=0.29,95%CI: 0.15-0.53; college or above:aOR=0.22,95%CI: 0.11-0.42). Conclusions: The prevalence of frailty in middle-aged and elderly community residents was significantly higher in island area than in mountainous area in Taizhou. The frailty-related factors varied with area. The elderly people (≥75 years) and women in island area had higher risk for frailty. Older age and suffering from depression were the independent risk factors for frailty. It is necessary to pay attention to the health risk factors and special environment in island area, and take comprehensive intervention measures to delay the process of debilitation and improve the quality of life of middle-aged and elderly people.

Abstract
BACKGROUND Thyroid nodules are common lesions in benign and malignant thyroid diseases. More and more studies have been conducted on the feasibility of artificial intelligence (AI) in the detection, diagnosis, and evaluation of thyroid nodules. The aim of this study was to use bibliometric methods to analyze and predict the hot spots and frontiers of AI in thyroid nodules. METHODS Articles on the application of artificial intelligence in thyroid nodules were retrieved from the Web of Science core collection database. A website (https://bibliometric.com/), VOSviewer and CiteSpace software were used for bibliometric analyses. The collaboration maps of countries and institutions were analyzed. The cluster and timeline view based on cocitation references and keywords citation bursts visualization map were generated. RESULTS The study included 601 papers about AI in thyroid nodules. China contributed to more than half (52.41%) of these publications. The cluster view and timeline view of co-citation references were assembled into 9 clusters, "AI", "deep learning", "papillary thyroid carcinoma", "radiomics", "ultrasound image", "biomarkers", "medical image segmentation", "central lymph node metastasis (CLNM)", and "self-organizing auto-encoder". The "AI", "radiomics", "medical image segmentation", "deep learning," and "CLNM", emerging in the last 10 years and continuing until recent years, were included. CONCLUSION An increasing number of scholars were devoted to this field. The potential future research hotspots include risk factor assessment and CLNM prediction of thyroid carcinoma based on radiomics and deep learning, automatic segmentation based on medical images (especially ultrasound images).

Abstract
Peanut skin (PS) contains various flavonoids and phenols that have antitumor and antioxidant effects. However, no research has been conducted on PS and hepatocellular carcinoma (HCC). Therefore, this study sought to explore the potential mechanism of PS in treating HCC. PS was searched for in the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and SYMMAP databases. HCC targets were searched for in five major databases. Protein-protein interaction network, Gene Ontology, and Kyoto Encyclopedia of Genes and Genomes analyses were performed. Molecular docking and molecular dynamics simulation were used for verification. Furthermore, in vitro experiments were used to verify the regulation of PS on human HCC (HepG2) cells. Ten ingredients and 95 common targets were identified for PS and HCC, respectively. The key targets of ingredients mainly relate to pathways such as hepatitis B, lipid and atherosclerosis, advanced glycation end products (AGEs)-AGE receptors (RAGEs) signaling pathway in diabetic complications, interleukin-17 (IL-17) signaling pathway, mitogen activated kinase-like protein (MAPK) signaling pathway, the PI3K-Akt signaling pathway. In addition, the molecular docking and molecular dynamics simulation analysis indicated the ingredients had strong binding ability with the targets. Moreover, in vitro experiments confirmed that luteolin can promote the apoptosis of HepG2 cells by controlling the expression of phosphorylated protein-tyrosine kinase (p-AKT). This study provides preliminary evidence that PS produces a marked effect in regulating multiple signaling pathways in HCC through multiple ingredients acting on multiple core genes, including AKT serine/threonine kinase 1 (AKT1), MYC, caspase 3 (CASP3), estrogen receptor 1 (ESR1), epidermal growth factor receptor (EGFR), jun proto-oncogene(JUN), and provides the basis for follow-up research to verify the mechanism of action of PS in treating HCC.

Abstract
BACKGROUND Clear cell renal cell carcinoma (ccRCC) is a common type of tumor that can metastasize to any organs and sites. However, it is extremely rare for ccRCC to metastasize to the iris. Here, we describe a rare case of iris metastasis from ccRCC with a history of left nephrectomy in 2010. CASE SUMMARY A 62-year-old male was admitted to the hospital due to blurred vision and red eyes, and a mass was found on the iris in the right eye. B-scan ultrasonography revealed a well-bounded high-density lesion at the corner of the anterior chamber at the 3-4 o'clock position. Phacoemulsification with simultaneous intraocular lens implantation and iridocyclectomy was performed in the right eye. The lesion was confirmed to be metastatic ccRCC by histological and immunohistochemical analyses. The patient was still alive at 9 mo after surgical treatment. Ocular metastasis can be an initial sign with a poor prognosis. Timely detection and treatment may improve survival. Clinicians should pay attention to similar metastatic diseases to prevent misdiagnosis leading to missed treatment opportunities. CONCLUSION This report of the characteristics and successful management of a rare case of iris metastasis from ccRCC highlights the importance of a comprehensive medical history, histopathology, immunohistochemistry, and clinical manifestation for successful disease diagnosis.

Abstract
PURPOSE To develop and evaluate the performance of radiomics-based computed tomography (CT) combined with machine learning algorithms in detecting occult vertebral fractures (OVFs). MATERIALS AND METHODS 128 vertebrae including 64 with OVF confirmed by magnetic resonance imaging and 64 corresponding control vertebrae from 57 patients who underwent chest/abdominal CT scans, were included. The CT radiomics features on mid-axial and mid-sagittal plane of each vertebra were extracted. The fractured and normal vertebrae were randomly divided into training set and validation set at a ratio of 8:2. Pearson correlation analyses and least absolute shrinkage and selection operator were used for selecting sagittal and axial features, respectively. Three machine-learning algorithms were used to construct the radiomics models based on the residual features. Receiver operating characteristic (ROC) analysis was used to verify the performance of model. RESULTS For mid-axial CT imaging, 6 radiomics parameters were obtained and used for building the models. The logistic regression (LR) algorithm showed the best performance with area under the ROC curves (AUC) of training and validation sets of 0.682 and 0.775. For mid-sagittal CT imaging, 5 parameters were selected, and LR algorithms showed the best performance with AUC of training and validation sets of 0.832 and 0.882. The LR model based on sagittal CT yielded the best performance, with an accuracy of 0.846, sensitivity of 0.846, and specificity of 0.846. CONCLUSION Machine learning based on CT radiomics features allows for the detection of OVFs, especially the LR model based on the radiomics of sagittal imaging, which indicates it is promising to further combine with deep learning to achieve automatic recognition of OVFs to reduce the associated secondary injury.

Abstract
Dichlorvos poisoning can cause muscarinic (M) -like symptoms, nicotinoid (N) -like symptoms and central nervous system manifestations. When severe poisoning is combined with refractory shock, the mortality rate exceeds 60%. At present, there are more and more studies on ECMO for poisoning, but there is no report on ECMO for treating refractory hypotension caused by dichlorvos poisoning. We analyzed 3 successful cases of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in the treatment of refractory shock caused by acute severe dichlorvos poisoning to explore the effectiveness of VA-ECMO in patients with severe poisoning.

Abstract
Objective: To understand the incidence and causes of HIV/AIDS death patients in Taizhou from 1998 to 2022. Methods: The data were collected from the AIDS Integrated Prevention and Control Information System of China Information System for Diseases Control and Prevention and Taizhou Chronic Disease Information Management System. By the end of 2022, a total of 5 126 HIV/AIDS patients living in Taizhou for a long time were included, SAS 9.4 was used for Kruskal-Wallis test, χ2 test and trend analysis. Results: From 1998 to 2022, a total of 796 HIV/AIDS patients died, with a fatality rate of 15.53% (796/5 126), in whom 52.26% (416/796) died within one year after confirmation. The proportion of HIV/AIDS patients who died within one year decreased (trend χ2=5.60, P<0.001). For the constituent of death causes, there were 140 (17.59%) deaths of AIDS, 237 (29.77%) deaths of malignant tumors, 99 (12.44%) deaths of cardiovascular disease, 58 (7.29%) deaths caused by injuries, 160 (20.10%) deaths due to other causes, and 102 (12.81%) deaths due to unknown causes. The constituent ratio of deaths of malignant tumor, cardiovascular disease and other causes increased over time (trend χ2=1.92, P=0.028; trend χ2=2.81, P=0.003; trend χ2=2.07, P=0.020). There were differences in the distribution of death causes in HIV/AIDS cases in terms of age, occupation, marital status, ethnic group, educational level and mode of transmission (all P<0.05). The average age of the death cases due to cardiovascular disease was higher than other death cases, the cases who died from AIDS had shorter survival time and the lower initial CD4+T cells after confirmation compared with all other death cases, and the time interval from confirmation to treatment in HIV/AIDS patients with unknown death causes was longer than those of all other death cases (all P<0.05). Conclusions: The constituent ratio of non-AIDS related deaths in HIV/AIDS patients in Taizhou was relatively high and showed an upward trend during 1998-2022. It is necessary to further strengthen the early screening, prevention and treatment of chronic non infectious diseases.

Abstract
To evaluate the predictive value of early warning scores for intensive care unit (ICU) admission in patients with coronavirus disease 2019 (COVID-19). For COVID-19 patients who were admitted to Shijiazhuang People's Hospital from January 2021 to February 2021, national early warning score (NEWS), national early warning score 2 (NEWS2), rapid emergency medicine score (REMS), quick sepsis-related organ failure (qSOFA), altered consciousness, blood urea nitrogen, respiratory rate, blood pressure, and age-65 (CURB-65) were used to evaluate the inpatient condition and the predictive value for ICU admission. A total of 368 patients were included, and 32 patients (8.7%) were transferred to the ICU. The median age was 49.0 (34.0,61.0) years. The scores of NEWS, NEWS2, REMS, and CURB-65 were 1 (0, 2), 1 (0, 2), 4 (2, 6) and 0 (0, 1), respectively. The receiver operating characteristic (ROC) cure (AUC) was used to evaluate the predictive value in detecting patients who are at risk of being transferred to the ICU. Area under the ROC AUC of NEWS was 0.756, sensitivity 65.6%, and specificity 71.3%. ROC AUC of NEWS2 was 0.732, sensitivity 62.5%, and specificity 61.3%. ROC AUC of REMS was 0.787, sensitivity 84.4%, and specificity 64.6%. ROC AUC of CURB-65 was 0.814, sensitivity 81.3%, and specificity 76.8%. The predictive value of NEWS and NEWS2 combined with age were significantly improved. The ROC AUC of NEWS combined with age was 0.885, sensitivity 85.1%, and specificity 75.0%. The ROC AUC of NEWS2 combined with age was 0.883, sensitivity 84.2%, and specificity 75.0%. NEWS and NEWS2 combined with age can be used as a predictive tool for whether COVID-19 patients will be admitted to the ICU.

Abstract
A novel strategy for the synthesis of 2-arylethenesulfonyl fluorides from nitrones and ethenesulfonyl fluoride (ESF) by the activation of the C-H bond using an inexpensive and readily available Ru-catalyst has been developed. In this process, the directing group can be concomitantly converted to an amide group. Interestingly, changing the substituent of the nitrogen of nitrones from a tert-butyl to a methyl group resulted in the formation of cyclic isoindolinones. Detailed mechanistic studies are also presented.

Abstract
To explore prognostic factors in intermediate-risk acute myeloid leukemia (AML) patients with minimal residual disease (MRD) negativity (MRD<0.1%,MRD-)receiving autologous hematopoietic stem cell transplantation (auto-HSCT).A total of 59 intermediate-risk AML patients with MRD-were treated with auto-HSCT from January 2015 to September 2021 at Affiliated People's Hospital of Ningbo University. The clinical data and laboratory results were collected retrospectively. Efficacy, clinical outcome and prognostic factors were analyzed. Univariate analysis was conducted by using log-rank test, the multivariate analysis by Cox proportional risk model.Among 59 patients, there were 27 males and 32 females with median age of 55 (31-69) years old.The median follow-up was 761(317-1 861)days. The 2-year overall survival (OS) rate and event-free survival (EFS) rate were 76.1%±11.4% and 73.4%±11.6% respectively.The univariate analysis showed that age older than 50 years, TET2 gene mutation (TET2+), achieving MRD negativity over 30 days (MRD30+) were unfavorable factors of OS (χ2=6.20, 33.20, 7.18;P=0.013,<0.001, 0.007). TET2+, WT1 gene mutation (WT1+), CD34+cells<2×106/kg, MRD30+were negative factors of EFS (χ2=17.29, 4.47, 3.94, 9.393;P<0.001, 0.035, 0.047, 0.002).Multivariate analysis showed that MRD30+, TET2+ were independent prognostic factors of OS and EFS (OS:HR=9.251, 25.839, P=0.036, 0.001;EFS:HR=5.851, 9.199, P=0.043, 0.002). Intermediate-risk AML patients with MRD30+or TET2+ have very poor prognosis after auto-HSCT. Alternative regimens should be investigated.

Abstract
Realizing quantum speedup for practically relevant, computationally hard problems is a central challenge in quantum information science. Using Rydberg atom arrays with up to 289 qubits in two spatial dimensions, we experimentally investigate quantum algorithms for solving the Maximum Independent Set problem. We use a hardware-efficient encoding associated with Rydberg blockade, realize closed-loop optimization to test several variational algorithms, and subsequently apply them to systematically explore a class of graphs with programmable connectivity. We find the problem hardness is controlled by the solution degeneracy and number of local minima, and experimentally benchmark the quantum algorithm's performance against classical simulated annealing. On the hardest graphs, we observe a superlinear quantum speedup in finding exact solutions in the deep circuit regime and analyze its origins.

Abstract
Novel boronic acid-functionalized magnetic multi-walled carbon nanotubes with flexible branched polymer (Fe3O4@MWCNTs@ε-PL@BA) nanocomposites were fabricated and applied as the desorption/ionization matrix for the MALDI-TOF-MS determination of low molecular weight flavonoids. The prepared nanocomposite was systematically characterized by various techniques. Compared to the traditional organic matrix, the proposed Fe3O4@MWCNTs@ε-PL@BA matrix has excellent ionization efficiency and low-background noise interference due to the MWCNTs unique electron-phonon interaction and the high introduction density of boronic acid functional groups. Good sensitivity and ultra-high salt tolerance of the Fe3O4@MWCNTs@ε-PL@BA-assisted MALDI-TOF-MS were permitted for the determination and quantification of flavonoids in actual samples. Noticeably, the limits of detection (LODs) for the target flavonoids were in the range 17-33 nM. The relative standard deviations (RSDs) of spot-to-spot and sample-to-sample (n = 10) were ≤ 9.8% and ≤ 10.1%, respectively. Furthermore, the wide linear ranges (0.1 - 500 µg/mL) and satisfactory calibration plot coefficients (R2 > 0.99) of flavonoids were achieved by MALDI-TOF-MS with the Fe3O4@MWCNTs@ε-PL@BA matrix. Good recoveries (92-105.5%) were achieved for the target flavonoids in practical food samples. Hence, the prepared Fe3O4@MWCNTs@ε-PL@BA nanocomposites have applications in the selective and efficient capture of target flavonoids active biomolecules coupled with MALDI-TOF-MS determination in actual samples.

Abstract
In this work, quercetin was loaded in the highly-porous lactose via the adsorption of quercetin molecules in ethanol. The method aims to improve the quercetin solubility and the loading capacity of lactose. The method relates to the synthesis of the highly-porous lactose with a particle size of ∼35 μm, a mean pore width of ∼30 nm, a BET surface area of 35.0561 ± 0.4613 m2/g, and a BJH pore volume of ∼0.075346 cc/g. After the quercetin loading in ethanol, BET surface area and BJH pore volume of porous lactose were reduced to 28.8735 ± 0.3526 m2/g and 0.073315 cc/g, respectively. The reduction rate was based on the quercetin loading efficiency of highly-porous lactose. DSC analysis and XRD analysis suggest that the sediments of quercetin in the nanopores of porous lactose are crystalline. FTIR spectroscopy results suggest that there is no significant interaction between quercetin and lactose. The highly-porous lactose had a higher loading efficiency of 20.3% (w/w) compared to the α-lactose (with 5.2% w/w). The release rates of quercetin from the highly-porous lactose tablets were faster compared to the conventional α-lactose carrier.

Abstract
Objective: To analyze the protein expression differences of lacrimal gland adenoid cystic carcinoma (LACC) with high-grade transformation (HGT). Methods: Experimental study. A total of 8 paraffin tissue samples were collected in Tianjin Medical University Eye Hospital from December 2012 to January 2019. According to pathological examination, the samples were divided into the LACC group and the LACC-HGT group, with 4 cases in each group. The LACC group included 2 male samples and 2 female samples, with an average age of 53 years. The LACC-HGT group included 2 male samples and 2 female samples, with an average age of 44 years. Primary cells were cultured from fresh tumor tissue. Isobaric tags for relative and absolute quantification techniques were used to screen the differentially expressed proteins between the two groups, and bioinformatics analysis was conducted for the differentially expressed proteins. Microarray was used to screen differentially expressed mRNAs between LACC and LACC-HGT primary cells. The mass spectrum data were intersected with mRNA microarray data, and quantitative real-time (qRT) PCR was performed to verify the results. Proteomics and microarray data were compared using the independent sample t test. The qRT-PCR data were compared pairwise by one-way analysis of variance. Results: A total of 105 HGT-related differential proteins were detected in this study, including 50 up-regulated proteins and 55 down-regulated proteins. The significantly up-regulated proteins included hemoglobin subunit beta, hemoglobin subunit alpha 1, and collagen type Ⅵ alpha 2 chain; the significantly down-regulated proteins included Cereblon, adenosylhomocysteinase like 2, and ribosomal protein L39 pseudogene 5. Gene ontology analysis results showed that the LACC-HGT differential proteins were mainly located in the cytoplasm, vesicle cavity, and extracellular matrix, had organic acid binding and molecular carrier activity, and participated in the regulation of extracellular matrix composition, immunity, inflammation, apoptosis, and other biological processes. Pathway analysis showed that the LACC-HGT differential proteins were mainly involved in signal pathways such as mitogen-activated protein kinase signal pathway and extracellular matrix proteoglycans and glycan metabolism signal pathway. Protein complex prediction analysis screened out 4 up-regulated protein complexes and 1 down-regulated protein complex. There were 15 LACC-HGT differential proteins that overlapped with mRNA chip differential genes, of which 6 were tumor-related proteins including collagen type XIV alpha 1 chain (COL14A1), EMAP like 4 (EML4), inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4), NDRG family member 2 (NDRG2), osteoglycin (OGN) an Ras homolog family member C (RhoC). The main function was the movement and migration of tumor cells. The qRT-PCR results showed that the relative expression levels of COL14A1, EML4, ITIH4, NDRG2, OGN, and RhoC in primary LACC-1, LACC-2, LACC-HGT-1, and LACC-HGT-2 cells were significantly different (F=1 675.98, 38.53, 27.37, 16.47, 13.38, 25.22, all P<0.01). For example, the relative expression of COL14A1 in primary LACC-HGT-1 (16.09±0.51) and LACC-HGT-2 (9.96±0.34) cells was significantly higher than that in primary LACC-1 (1.00±0.13) and LACC-2 (0.67±0.08) cells (all P<0.05). Conclusion: There are differentially expressed proteins between LACC-HGT and LACC, among which COL14A1, EML4, ITIH4, NDRG2, OGN, and RhoC may play an important role in LACC-HGT and can be used as potential targets of LACC-HGT in further study.

Abstract
CCAAT enhancer-binding protein alpha (CEBPA, also known as C/EBPα) is a transcription factor that plays an essential role in regulating terminal differentiation and cell proliferation of many tissues. The objective of this study was to explore the potential function of CEBPA in ovarian cancer. The expression of CEBPA in ovarian cancer samples and adjacent normal tissues was evaluated by qRT-PCR. The putative role of CEBPA in ovarian cancer cells was evaluated by immunohistochemistry, western blot, cell viability assay, BrdU incorporation assay, soft agar colony formation assay, Transwell cell migration and invasion assay, tumor xenograft formation, and lung metastasis model. We found that CEBPA was downregulated in ovarian cancer samples and predicted a poor prognosis. CRISPR/Cas9-mediated CEBPA knockout promoted proliferation, anchorage-independent growth, migration, invasion, and EMT of ovarian cancer cells, while enforced CEPBA expression suppressed proliferation, anchorage-independent growth, migration, invasion, EMT, tumor xenograft growth, and lung metastasis of ovarian cancer cells. Furthermore, we found that the knockout of CEBPA activated Wnt/β-catenin signaling in ovarian cancer cells, while CEBPA overexpression suppressed Wnt/β-catenin activation. Our data indicated that CEBPA acted as a tumor suppressor in ovarian cancer, and might be a potential prognostic marker for ovarian cancer treatment.

Abstract
The control of nonequilibrium quantum dynamics in many-body systems is challenging because interactions typically lead to thermalization and a chaotic spreading throughout Hilbert space. We investigate nonequilibrium dynamics after rapid quenches in a many-body system composed of 3 to 200 strongly interacting qubits in one and two spatial dimensions. Using a programmable quantum simulator based on Rydberg atom arrays, we show that coherent revivals associated with so-called quantum many-body scars can be stabilized by periodic driving, which generates a robust subharmonic response akin to discrete time-crystalline order. We map Hilbert space dynamics, geometry dependence, phase diagrams, and system-size dependence of this emergent phenomenon, demonstrating new ways to steer complex dynamics in many-body systems and enabling potential applications in quantum information science.

Abstract
OBJECTIVE To obtain the transcriptome data of Tyrophagus putrescentiae, so as to provide insights into the subsequent functional studies. METHODS The mixture of male and female T. putrescentiae was sequenced using the Illumina HiSeqTM 2000 high-throughput sequencing platform. Unigenes were obtained after assembling the sequencing data using the Trinity software and compared with the protein sequences in the RefSeq non-redundant protein sequence (NR) database, nucleotide sequence (NT) database, Swiss-Prot database, Kyoto encyclopedia of genes and genomes (KEGG) database and clusters of orthologous groups (COG) database, and the function of the Unigenes was annotated. In addition, the coding DNA sequences (CDS) were predicted through alignment of the Unigenes in NR and Swiss-Prot protein databases. The SSR loci were identified by analysis of the Unigenes in T. putrescentiae with the MISA software, and the SNPs were detected using the SOAPsnp technique. RESULTS A total of 4.67 GB high-quality data were obtained from raw sequencing data. A total of 51 271 Unigenes were obtained after assembling the sequencing data, with a total length of 41 848 995 nucleotide (nt) and a mean length of 816 nt. A total of 29 053 annotated Unigenes were obtained following comparisons with the public protein databases, and 27 443 CDS were predicted. In addition, there were 23 092 SSR loci and 148 027 SNPs identified. CONCLUSIONS The database of T. putrescentiae transcriptome is created by sequencing, and a large number of T. putrescentiae transcripts are obtained, which provides a basis for the subsequent functional studies of allergy-related genes.

Abstract
The COVID-19 pandemic has altered and reshaped the delivery of oral and maxillofacial surgery (OMS) over the past few months. As the USA gradually lifts restrictions and re-opens, surgeons must adjust accordingly. Therefore, the OMS Resurgence Conference: Safely Resuming Practice with a New Normal was organized for 11 May 2020 to gather and disseminate expert opinions and recommendations for OMSs to thoughtfully resume work with efficiency and safety. This manuscript offers a summary of the highlights from the conference discussion.

Abstract
Objective: To observe the clinical effects of CT-guided chemical destructive block of lumbar sympathetic nerve in the treatment of cold sensation of limbs. Methods: In this retrospective analysis, clinical data of 43 patients with cold sensation of limbs treated by lumbar sympathetic chemical destructive block in the Affiliated Hospital of Jiaxing University from January 2015 to January 2018 were collected. The changes of heart rate, non-invasive blood pressure (NIBP), oxygen saturation (SpO(2)), plantar temperature and peripheral perfusion index (PI) of patients were recorded and analyzed before treatment and 5 min after injection of anhydrous ethanol. The patients were followed up at postoperative 1 day, 1 week, 1 month, 3 months, 6 months, 1 year and 2 years. Results: Fourty-three patients underwent bilateral lumbar sympathetic nerve chemical destructive block under the CT-guided, and all patients were punctured to the target successfully. The PI of patients before and after treatment were 1.2±0.6, 7.2±3.0 respectively, which was significantly increased after treatment compared with before treatment, and the difference was statistically significant (t=12.386, P<0.05). The plantar temperature of patients before and after treatment respectively were (29.6±1.7)℃, (34.6±1.1)℃, which was significantly increased after treatment compared with before treatment, and the difference was statistically significant (t=15.057, P<0.05). There were no significant differences in heart rate, NIBP and SpO(2) between before and after treatment (all P>0.05). Lumbar sympathetic chemical destructive block was clinically effective in 39 patients (90.7%) and ineffective in 4 patients (9.3%). Among the 39 clinically effective patients, the curative effects were excellent in 29 cases and improved in 10 cases. Postoperative recurrence occurred in 10 cases (25.6%).

Abstract
The ruthenium-catalyzed activation of the C4 position of coumarins for coupling with acrylates was described using modifiable ketone as a directing group. The alkenylation reaction provided a direct approach to prepare previously inaccessible 4-alkenylated coumarins with operational simplicity and high atom-economy. This protocol also worked well with coumarin-3-carboxylic acids to unveil a rare instance of a tandem alkenylation/decarboxylation reaction. The potential value of this approach was further highlighted by the efficient synthesis of several heterocyclic fused coumarin derivatives.

Abstract
AIMS It has been reported that allopregnanolone (APα) promotes the neurogenesis of the neural progenitor cells (NPCs) in the subventricular zone (SVZ) and prevents the decrease of dopaminergic neurons in 6-hydroxydopamine (6-OHDA)-treated mice by binding to γ-aminobutyric acid A receptor (GABAAR) and then opening voltage-gated L-type Ca2+ channel, but the underlying mechanisms remain elusive. The aim of this study was to explore the possible involvement of GABAAR and calcium/calmodulin-dependent protein kinase II delta 3 (CaMKIIδ3) in this process. METHODS 6-OHDA-treated mice and primary cultured midbrain cells were administrated with APα and GABAAR antagonist bicuculline (Bic), and the proliferation and differentiation of NPCs, the tyrosine hydroxylase (TH)-positive neurons and their fibers, the expression levels of CaMKIIδ3 and brain-derived neurotrophic factor (BDNF), and motor functions were measured using ELISA, immunohistochemical staining, real-time RT-PCR, Western blot, and behavioral test. RESULTS Allopregnanolone significantly promoted the phosphorylation of cytoplasmic CaMKIIδ3 and its nuclear translocation by binding to GABAAR, which, in turn, increased the expression levels of BDNF. This may account for the findings that the exogenous APα enhanced the proliferation and differentiation of NPCs, and ameliorated the nigrostriatal system and behavioral performance in 6-OHDA-treated mice. CONCLUSIONS Allopregnanolone may directly activate GABAAR, which, in turn, enhance the proliferation and differentiation of NPCs via upregulating the expression levels of CaMKIIδ3, and finally contribute to the restoration of dopaminergic neurons in 6-OHDA-treated mice.

Abstract
BACKGROUND To investigate the relationship between serum lipid levels and disease progression during chronic hepatitis B virus infection. METHODS We selected 73 healthy controls and 163 patients with chronic HBV infection as the study subjects. The chronic HBV infection patients were divided into the HBV carrier group (74 patients), chronic hepatitis B group (71 patients), and liver cirrhosis group (21 patients). The age, gender, body mass index, blood lipid index, liver function index, and HBV DNA levels of all participants were tested and recorded. A t-test or the Mann-Whitney U test was used to compare the data between two groups; data from multiple groups were compared using one-way ANOVA or the Kruskal-Wallis Test. RESULTS We observed that the serum HDL cholesterol (1.00 ± 0.30 mmol/L in the HBV-infected group, 1.29 ± 0.23 mmol/L in the control group) and APOA (1.29 ± 0.35 mmol/L, 1.36 ± 0.21 mmol/L, respectively) concentrations were significantly lower in the HBV-infected group than in the control group (p < 0.05). As the disease progressed, the blood lipid and lipoprotein values were significantly lower in the cirrhosis group TC (3.26 ± 1.00 mmol/L), HDL cholesterol (0.77 ± 0.33 mmol/L), LDL cholesterol (2.09 ± 0.62 mmol/L), and APOB (0.57 ± 0.18 mmol/L) compared with the control group, the carrier group, and the chronic hepatitis B group (p < 0.05). The serum HBV DNA level was significantly, positively correlated with the blood HDL concentration (carrier group R = 0.340, p = 0.02; chronic hepatitis B group R = 0.329, p = 0.014). There was no correlation between the HBV DNA and lipid levels in patients with cirrhosis. CONCLUSIONS Serum lipid metabolic derangement was associated with disease progression during chronic HBV infection. Liver function and blood lipid levels were significantly lower in patients with hepatitis B-related cirrhosis.

Abstract
Objective: To study the characteristics and clinical significance of pulmonary function test and kerbs von den lungen 6 (KL-6) in anti-synthetase syndrome related interstitial lung disease (ASSD-ILD) and idiopathic pulmonary fibrosis (IPF). Methods: The clinical data of 43 patients with ASSD-ILD (ASSD-ILD group) from May 2015 to May 2017 were collected retrospectively, including 12 males and 31 females, and 34 patients with IPF (IPF group) treated in the First Affiliated Hospital of Zhengzhou University during the same period, including 28 males and 6 females, were also included. The basic information, and the value of pulmonary function test [pulmonary function parameters included the forced vital capacity expressed as percent predicted (FVC%pred), the forced expiratory volume in 1 second expressed as percent predicted (FEV(1)%pred), the ratio of FVC to FEV(1) (FVC/FEV(1)), the peak expiratory flow expressed as percent predicted (PEF%pred), the forced expiratory flow at 25%, 50%, 75% of FVC as percent predicted (FEF(25)%pred, FEF(50)%pred, and FEF(75)%pred), the maximum mid-expiratory flow as percent predicted (MMEF% pred), and the diffusing capacity for carbon monoxide as percent predicted (DLCO% pred)], and serum KL-6 level in ASSD-ILD and IPF were compared. Results: The FEV(1)%pred, FEF(50)%pred, FEF(75)%pred, and MMEF%pred values in ASSD-ILD group were significantly lower than those in IPF group (all P<0.05), while the FVC% pred, FVC/FEV(1), PEF% pred, FEF(25)%pred, and DLCO% pred values in ASSD-ILD group had no significant difference compared with IPF group (all P>0.05). There was no significant difference in serum KL-6 level between ASSD-ILD group and IPF group [(1 169±911) vs (1 210±908) U/ml, t=0.62, P=0.463]. Follow-up analysis showed that the serum KL-6 level of ASSD-ILD patients who died within two years was significantly higher than that of survivors [(2 060±1 168) vs (1 042±858) U/ml, t=2.93, P=0.041]. The serum KL-6 level of patients who died within two years of IPF patients was also significantly higher than that of patients who survived [(1 767±865) vs (1 089±894) U/ml, t=2.53, P=0.026]. The serum KL-6 level in ASSD-ILD group was negatively correlated with FVC%pred (r=-0.43, P=0.004), FEV(1)%pred (r=-0.39, P=0.010) and DLCO% pred (r=-0.41, P=0.006). There was no correlation between serum KL-6 level and pulmonary function test indexes in IPF group (all P>0.05). Conclusions: There is difference in pulmonary function test between ASSD-ILD patients and IPF patients. High serum KL-6 level will be predictive of poor prognosis.

Abstract
Quantum entanglement involving coherent superpositions of macroscopically distinct states is among the most striking features of quantum theory, but its realization is challenging because such states are extremely fragile. Using a programmable quantum simulator based on neutral atom arrays with interactions mediated by Rydberg states, we demonstrate the creation of "Schrödinger cat" states of the Greenberger-Horne-Zeilinger (GHZ) type with up to 20 qubits. Our approach is based on engineering the energy spectrum and using optimal control of the many-body system. We further demonstrate entanglement manipulation by using GHZ states to distribute entanglement to distant sites in the array, establishing important ingredients for quantum information processing and quantum metrology.

Abstract
Objective: To evaluate the effectiveness of health belief model-based health education intervention in improving blood pressure control of patients with hypertension in community settings. Methods: From September 2016 to September 2017, 400 newly diagnosed patients with hypertension were recruited from 6 community healthcare centers with comparable population size and health services in the Shunyi District of Beijing. All community healthcare centers were randomly assigned to the intervention group (206 patients) and the control group (194 patients). Patients in the intervention group received 3 lectures (20-30 min for each) of health belief model-based health education. Patients in the control group received usual care. The basic characteristics, health beliefs, and health literacy were collected, and blood pressure was measured before and after the intervention, respectively. The difference-in-difference model was used to analyze the change of blood pressure and the influencing factors between two groups before and after the intervention. Results: A total of 134 patients in the intervention group and 129 patients in the control group completed the study. After adjusting for the age, gender, family income, medical insurance, chronic diseases and family history, the score of perceived barriers was increased by 1.65 (P=0.016), and perceived seriousness was decreased by 0.73 (P=0.018). The systolic blood pressure of patients was decreased by 7.37 mmHg (1 mmHg=0.133 kPa, P=0.001) and diastolic blood pressure was decreased by 4.07 mmHg (P=0.014), respectively. The β (95%CI) values were -7.37 (-11.88,-2.86) and -4.07 (-7.30, -0.84). The perceived susceptibility and self-efficacy had a significant influence on the blood pressure of patients (P<0.05). Conclusion: Health belief model-based health education intervention could significantly improve the blood pressure control of patients with hypertension in the community settings.

Abstract
Objective:To investigate the clinical value of intraoperative parathyroid hormone monitoring in operation of patients with secondary hyperparathyroidism(SHPT). Method:A retrospective analysis was carried out and enrolled, including 100 primary surgery and 14 second surgery. The data of 100 patients with primary surgery and 14 patients with reoperation were retrospectively analyzed. The criterion, predicting the success of surgery, is that the measured iPTH level declines by more than 80% compared with that before surgery, 20 minutes after the last parathyroid gland removed. Serum calcium, serum phosphorus and iPTH tested pre-and post-operation were statistically analyzed. Result:112 cases(98 cases in the first operation and 14 cases in the second operation) were cured by operation and the cure rate is 98.2%. In 109 cases(97 cases of first operation and 12 cases of reoperation), the intraoperative determination of parathyroid hormone was up to standard, and the sensitivity of predicting the success of surgery was 97.0% and 85.7%, respectively. Postoperative clinical symptoms such as joint pain and skin itching, etc. were significantly improved or disappeared. Postoperative iPTH, serum calcium and serum phosphorus were significantly different from those before surgery, and the difference was statistically significant(P<0.05). Conclusion:Intraoperative parathyroid hormone monitoring has vital clinical guiding value for SHPT, and can improve the success rate significantly. A more than 80% reduction in iPTH at 20 min after the last parathyroidectomy was a good predictor of successful surgery.

Abstract
Chicken, duck, egg, and duck egg samples from the Yangtze River Delta and Pearl River Delta regions in China were analyzed for 17 perfluorinated compounds (PFCs). The concentrations of PFCs in chicken and duck livers ranged from <LOD to 35.53 μg/kg and 40.41 μg/kg, respectively, which is higher than in other tissues. PFDA was the predominant PFC in live with mean concentrations of 2.09 μg/kg and 1.73 μg/kg in chicken and duck livers, respectively. The mean ∑PFCs concentrations were 1.87 μg/kg and 1.88 μg/kg in chicken and duck eggs, respectively. The mean PFC concentrations were also similar in the subcutaneous fat of both chicken and duck. The total PFC concentrations in chicken and ducks ranged from <LOD to 54.63 μg/kg and 10.21 μg/kg. The current concentration levels of PFCs would not cause health risks to adults even with the frequent consumption of poultry products. However, the higher concentrations of PFCs in chicken and chicken eggs might cause health risks in children.

Abstract
Objective: To compare the sensitivity of 8-color panels and next generation flow cytometry (NGF) for detecting minimal residual disease of multiple myeloma patients. Methods: 8-color-membrane antigens (8C-Mem) panel was built including CD45, CD38, CD138, CD19, CD56, CD81, CD27 and CD117 to identify the plasma cells, while 8-color-cytoplasmic antigens (8C-Cyto) panel was built including CD45, CD38, CD138, CD19, CD56, CD81, cKappa (cK) and cLambda (cλ) , and 8-color-two-tubes (8C-2tubes) panel were built including 8C-Mem and 8C-Cyto panels, the data of three groups was analyzed by Diva software. NGF uses Infinicyt software to fuse 8C-2tubes data to further analyze the expression of plasma antigens. Bone marrow aspiration obtained from 20 controls and 76 multiple myeloma patients who achieved complete remission were measured and analyzed. Results: Positive MRD samples were discriminated in 88.2% of the specimen evaluated through either abnormal plasma cells (aPCs) or clonal plasma cells (cPCs) by NGF antigens panel, Among of them, consistency was 94.7%. The median percentage of cPCs was 0.3530%, The lowest sensitivity of NGF was 0.0003%. In 8-color panels, the positive MRD rates of 8C-Mem, 8C-Cyto and 8C-2tubes panels were 84.2%, 85.5% and 86.8%, respectively, which lower than that of NGF (P<0.001) . The positive MRD rate of 8C-Mem and 8C-Cyto panels were lower than that of 8C-2tubes panel (P<0.001) , and the positive MRD rate of 8C-Mem panel was lower than that of 8C-Cyto panel (P<0.001) . Sensitivity and specificity of NGF was higher than that of 8-color panels. 8C-2tubes panel has the best sensitivity, accuracy, negative predicted value, positive predicted value and specificity than other 8-color panels. However, huge data and low efficiency for analysis is the disadvantage. 8C-Cyto panel was the second choice, and 8C-Mem panel was the last. Conclusions: Membrane and cytoplasmic light chain is a better method for multiple myeloma-MRD detection and NGF panel is an ideal approach. 8C-Cyto panel is recommended in 8-MFC groups.

Abstract
Objective: To evaluate the significance of different clinicopathologic features on prognosis of patients with squamous cell carcinoma of vulva. Methods: We retrospectively analyzed the prognostic relevance of different clinicopathological variables of 201 patients with squamous cell carcinoma of vulva treated in Cancer Hospital, Chinese Academy of Medical Sciences. The data including age, initial symptoms, stage, location, tumor size, histological grade, number and size of metastatic lymph nodes, treatment mode, and presence of leukoplakia vulva was used to evaluate the prognosis of vulvar squamous cell carcinoma. Results: The median age of onset was 62.0 years old, with 74 patients in stage Ⅰ, 27 in stage Ⅱ, 55 in stage Ⅲ and 9 in stage Ⅳ. The median progression-free survival was 90.0 months. The 5-year progression-free survival rate of the total patients was 55.5%, while the 10-year progression-free survival rate was 48.5%. Univariate analysis showed statistically significant prognostic parameters included clinical stage, number of metastatic lymph nodes, tumor size and treatment mode (all P<0.001). Multivariate analysis showed that number of metastatic lymph nodes (P<0.05) was an independent prognostic factor for progression-free survival. Conclusion: The study illustrates that number of metastatic lymph nodes represents important independent factor for progression-free survival of patients with vulvar squamous cell carcinoma.

Methods: Retrospective case series study.The clinical data of 4 adult patients with adult onset xanthogranuloma treated in the Tianjin Medical University Eye Hospital from 2015 to 2017 were analyzed. Results: There were 1 male and 3 females, aged 46-73 years, with an average age of 55 years. The duration of eyelid swelling was from 6 months to 6 years. One case was binocular and 3 cases were monocular. There were progressive enlargement of eyelid swelling and subcutaneous cord nodules with poor mobility and no tenderness in all 5 eyes. The eyelid skin in 2 patients (2 eyes) was bulging and yellow. CT examination showed swelling of the eyelids and soft tissue thickening in 5 eyes. There were lacrimal gland enlargement in 3 eyes, upper rectus muscle involvement in 3 eyes, external rectus muscle involvement in 1 eye, lower rectus muscle involvement in 1 eye, superior oblique muscle involvement in 1 eye, and involvement of both the superior and inferior rectus muscles in 1 eye. In 1 patient (1 eye), the lesion showed low and medium signals on T(1) weighted images and T(2) weighted images. Three patients (4 eyes) underwent color Doppler ultrasonography, showing the echo zone in the irregularly shaped eyelid was strong, the internal echo was uneven, the local echo was low, and the boundary was not clear. One of the eyes showed a blood flow signal. All patients underwent surgical resection. The pathological results showed infiltration of foamy tissue cells, Touton cells, lymphocytes and plasma cells. Immunohistochemistry demonstrated 3 patients (4 eyes) expressed CD68, and 1 patient (1 eye) expressed S-100. After 6 months to 2 years of follow-up, 3 patients had no recurrence. One patient developed eye discomfort at 6 months after surgery, and the symptoms were relieved after treatment with triamcinolone. Conclusions: Adult onset xanthogranuloma mainly manifest as eyelid swelling, periorbital mass and skin color changes, generally with no systemic involvement. Imaging examination mainly shows the involvement of soft tissues, lacrimal glands and muscles around the eyelids. The main features of the pathology are infiltration of foamy tissue cells, Touton giant cells, lymphocytes and plasma cells. (Chin J Ophthalmol, 2019, 55: 381-386).

Abstract
Brucea javanica is an important Chinese folk medicine traditionally used for the treatment of dysentery (also known as inflammatory bowel diseases). Brucea javanica oil emulsion (BJOE), the most common preparation of Brucea javanica, has a variety of pharmacological activities. In this follow-up investigation, we endeavored to illuminate the potential benefit of BJOE on 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced Crohn's disease (CD) in rats and decipher the mechanism of action. The result illustrated that BJOE treatment significantly reduced the body weight loss, disease activity index and macroscopic scores, ameliorated shortening of colon length, arrested colonic histopathological deteriorations, lowered the histological scores in parallel to the model group. Furthermore, BJOE also decreased the levels of MPO and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-17, IL-23 and IFN-γ), and increased the levels of anti-inflammatory cytokines (IL-4, IL-10 and TGF-β) as compared with the model group. In addition, the elevated mRNA expression of MMP-1, MMP-3 and RAGE induced by TNBS was remarkably inhibited by BJOE, SASP or AZA treatments, while the mRNA expression of PPAR-γ was significantly enhanced. Furthermore, the activation of TLR4/NF-κB signaling pathway was significantly inhibited by AZA and BJOE treatment when compared with that of TNBS-treated rats. Our study suggested that BJOE exerted superior therapeutic effect to SASP and AZA in treating TNBS-induced colitis in rats. The protective effect of BJOE may involve the inhibition of the TLR4/NF-κB-mediated inflammatory responses. These results indicated that BJOE held promising potential to be further developed into a novel candidate for the treatment of CD.

Abstract
A novel heterogeneous catalyst, the ionic liquid (IL) of 1-butyl-3-methylimidazolium acetate (BmimOAc) immobilized on MIL-101-NH2, denoted as IL(OAc-)-MIL-101-NH2, was prepared by the "ship-in-a-bottle" strategy. The IL of BmimOAc was prepared in the MIL-101-NH2 nanocages primordially, in which the condensation product of MIL-101-NH2's amine group with 1,1'-carbonyldiimidazole (CDI) reacted with 1-bromo butane, and then the intermediate exchanged with potassium acetate. The structure and physicochemical properties of IL(OAc-)-MIL-101-NH2 were characterized by powder X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, DRS UV-vis, nitrogen adsorption-desorption, and elemental analysis. The results indicated that BmimOAc was anchored in the MIL-101-NH2 skeleton via the acylamino group and confined in the nanocages in the form of a single molecule. The composite material of IL(OAc-)-MIL-101-NH2 exhibited excellent catalytic activity and catalytically synthesized 3-aryl-2-oxazolone in an excellent yield of 92%. It can be reused up to six times without noteworthy loss of its activity and demonstrated distinct size-selective property for substrates. It was conjectured that the diffusion kinetics of reactants could be controlled by the aperture size of the metal-organic framework support.

Abstract
Objective: To investigate the prognostic value of highly sensitive cardiac Troponin T (hs-cTn T) for sepsis in critically ill patients. Methods: Patients estimated to stay in the ICU of Fuxing Hospital for more than 24h were enrolled at from March 2014 to December 2014. Serum hs-cTn T was tested within two hours. Univariate and multivariate linear regression analyses were used to determine the association of variables with the hs-cTn T. Multivariable logistic regression analysis was used to evaluate the risk factors of 28-day mortality. Results: A total of 125 patients were finally enrolled including 68 patients with sepsis and 57 without. The levels of hs-cTn T in sepsis and non-sepsis groups were significantly different[52.0(32.5, 87.5) ng/L vs 14.0(6.5, 29.0) ng/L respectively, P<0.001]. In sepsis group, hs-cTn T among common sepsis, severe sepsis and septic shock were similar. Hs-cTn T was significantly higher in non-survivors than survivors [27(13, 52)ng/L vs 44.5(28.8, 83.5)ng/L, P<0.001]. Age, sepsis, serum creatinine were independent risk factors affecting hs-cTn T by multivariate linear regression analyses. But hs-cTn T was not a risk factor for death. Conclusion: Patients with sepsis had higher serum hs-cTn T than those without sepsis. but it was not found to be associated with the severity of sepsis.

Abstract
Objective: To investigate the effect and mechanisms of picroside Ⅱ on the brain tissue after cerebral ischemia reperfusion(I/R) in rats. Methods: The middle cerebral artery occlusion(MCAO) rat model was established by inserting a monofilament into middle cerebral artery. The experimental rats were treated by injecting picroside Ⅱ intraperitoneally. The modified neurological severity score (mNSS) and body weight were determined before modeling and after reperfusion of 22 h. The cerebral infarct volume was measured by TTC staining and the cerebral water content was measured in rats. At the same time, ROS content and NADPH oxidase activity were detected. The structure of neurons was observed by electron microscope and the mRNA and protein levels of Rac-1 and Nox2 were detected by RT-PCR and Western blotting. Results: After modeling, the mNSS score was significantly increased (12.6±1.3 vs 0, P<0.001), while the body weight was lost (13.3%±2.5% vs 4.9%±0.8%, P<0.01). The cerebral infarct volume increased obviously (33.5%±3.4% vs 0, P<0.001), brain water content increased significantly (81.5%±0.9% vs 77.7%±0.9%, P<0.05) and the structure of neuron was damaged obviously. The protein and mRNA levels of Rac-1 and Nox2 were significantly increased (P<0.05). After treatment with picroside Ⅱ, mNSS score decreased significantly (7.9±0.8 vs 12.6±1.3, P<0.05) and the body weight increased obviously (9.3%±1.1% vs 13.3%±2.5%, P<0.05). The infarct volume of brain was significantly reduced (18.2%±1.9% vs 33.5%±3.4%, P<0.05), brain water content decreased obviously (79.1%±0.7% vs 81.5±0.9%, P<0.05), the morphological structures of neurons was restored, and the expressions of Rac-1 and Nox2 were significantly decreased (P<0.05). Conclusion: It is suggested that picroside Ⅱ could exert antioxidation to protect the brain tissue through inhibiting the expression of Rac-1 and Nox2.

Abstract
Objective:To discuss the correlation of benign vocal cord lesions with occult vocal cord sulcus and the treatment of benign vocal cord lesions with occult vocal cord sulcus, through the analysis of surgical data, preoperative voice evaluation data and postoperative follow-up data of patients.Method:The data from 377 patients of benign vocal cord lesions with concealed vocal cord sulcus admitted to Beijing Tongren Hospital from 2005 to 2016 were reviewed. The follow-up time was more than half a year after surgery.Result:About 2.9% of the benign lesions of the vocal cords were associated with occult vocal cords sulcus,of which 61.27% were bilateral vocal cords sulcus,22.55% was right vocal cords sulcus,and 16.18% was left vocal cord sulcus.Of the patients with bilateral vocal fold sulcus,64.5% had benign vocal cord lesions and 35.5% had unilateral vocal cord benign lesions.Of the patients with unilateral vocal fold,73.97% were associated with ipsilateral vocal cord benign lesions, and 26.03% were associated with contralateral vocal cord lesions.In the 531 sides of the vocal cords sulcus,183 sides of vocal fold sulcus typeⅠwere not treated. The 332 sides of vocal fold sulcus type Ⅱ were treated with removed lesions of the vocal cords and microdissection of vocal cord adhesion.The 16 sides of vocal fold sulcus type Ⅲ were treated with removed lesions of the vocal cords,local tamponaded of autogenous abdominal fascia and microsutured to close the wound. There were 9 cases with 11 sides of vocal fold sulcus combined with the mucous bridge.The satisfactory rate of sound improvement was 80.37% in half a year after the operation.Postoperative fundamental frequency,jitter,shimmer and maximum phonation time were significantly improved compared with preoperative.Conclusion:The occurrence of benign vocal cord lesions may be related to occult vocal fold sulcus.Simultaneous treatment of benign vocal cord lesions with occult vocal cord sulcus can achieve satisfactory voice improvement.Therefore, we should pay attention to the treatment of vocal fold sulcus in the diagnosis and treatment of benign vocal cord diseases.
