Abstract
1. This study focused on the relationship between MITF mRNA expression and plumage colour in quail and the effect of promoter methylation on the expression of MITF mRNA.2. The CDS region of MITF mRNA was cloned by RT-PCR, followed by DNA sequencing. The RT-qPCR method was used to analyse the expression levels of MITF mRNA in dorsal skin tissue in Korean quail and Beijing white quail. The promoter region of the MITF gene was cloned, and the CpG island was predicted by the CpGplot program. The methylation levels of the CpG island were analysed using BS-PCR technology.3. Quail MITF mRNA contains a 1,476 bp complete ORF, which encodes a 492 amino acid residue protein. The MITF protein has no signal peptide or transmembrane region. The expression of MITF mRNA in dorsal tissue of Korean quail was significantly higher than that in Beijing white quail (p < 0.01). Abundant cis-elements and a 346 bp CpG island were found in the promoter region of the MITF gene. The average methylation level of the CpG island was 22 (22%) in Korean quail, and 46 (30%) in Beijing white quail (p < 0.05).4. The hypermethylation of the MITF gene promoter region in Beijing white quail resulted in a decrease in expression level, which was related to white feather colour.

Abstract
Objective: To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors. Methods: From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions. Results: Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects (χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients (χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications (χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment (R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not (OR=1.83, P<0.001). Conclusions: Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Abstract
Objective: To explore the trend and influencing factors of serum lipoprotein (a) (Lp(a)) concentration over time in Chinese community populations. Methods: This study is a prospective cohort study. The participants were enrolled from Chinese Multi-provincial Cohort Study- Beijing projects, completed the cardiovascular disease risk factor surveys in 2002 and 2007, and the serum Lp (a) concentration were measured. Based on the Lp(a) concentration at baseline (2002) and follow-up (2007), the participants were classified into subgroups of <30.0 mg/dl (1 mg/dl=0.01 g/L) group, 30.0 to 49.9 mg/dl group, and ≥50.0 mg/dl group, respectively. Multivariable logistic regression analysis was used to identify influencing factors associated with Lp (a) absolute change (≥20 mg/dl) and relative change (≥20%) within 5 years. Results: Among 1 955 participants with age of (56.5±8.0) years old and 821 male (42.0%) at baseline, there were 1 657 (84.8%), 184 (9.4%) and 114 (5.8%) participants in Lp(a)<30.0 mg/dl group, 30.0 to 49.9 mg/dl group and ≥50.0 mg/dl group, respectively. Among the baseline Lp(a) concentration of 30.0-49.9 mg/dl group, 68 (37.0%) participants progressed to Lp(a) ≥50.0 mg/dl after 5 years follow-up, and 102 (55.4%) remained at this level. Participants with baseline Lp(a)<30.0 mg/dl (92%, 1 524/1 657) or Lp(a)≥50.0 mg/dl (94.7%, 108/114) tended to be maintained at their respective levels. The results of the multivariate logistic regression analysis showed that, in addition to the high level of baseline Lp(a) concentration, family history of cardiovascular disease, elevated fasting blood glucose and usage of oral lipid-lowering drugs were the influencing factors of Lp(a) changes over time (P<0.05). Conclusions: Adults with borderline-high Lp(a) concentrations (30.0 to 49.9 mg/dl) could be considered for repeated testing, especially for those with a family history of cardiovascular disease, elevated fasting blood glucose and usage of statins.

Abstract
OBJECTIVE To analyze the RNA binding protein of Toxoplasma gondii (TgDDX39) using bioinformatics technology, and to evaluate the immunogenicity of TgDDX39, so as to provide insights into development of toxoplasmosis vaccines. METHODS The amino acid sequences of TgDDX39 were retrieved from the ToxoDB database, and the physicochemical properties, transmembrane structure domain, signal peptide sites, post-translational modification sites, coils, secondary and tertiary structures, hydrophobicity, and antigenic epitopes of the TgDDX39 protein were predicted using online bioinformatics tools, incluiding ProtParam, TMHMM 2.0, SignalP 5.0, NetPhos 3.1, COILS, SOPMA, Phyre2, ProtScale, ABCpred, SYFPEITHI and DNA-STAR. RESULTS TgDDX39 protein was predicted to be an unstable hydrophilic protein with the molecular formula of C2173H3458N598O661S18, which contained 434 amino acids and had an estimated molecular weight of 49.1 kDa and a theoretical isoelectric point of 5.55. The protein was predicted to have an extremely low possibility of signal peptides, without transmembrane regions, and contain 27 phosphorylation sites. The β turn and random coils accounted for 39.63% of the secondary structure of the TgDDX39 protein, and a coiled helix tended to produce in one site. In addition, the TgDDX39 protein contained multiple B and T cell antigenic epitopes. CONCLUSIONS Bioinformatics analyses predict that TgDDX39 protein has high immunogenicity and contains multiple antigenic epitopes. TgDDX39 protein is a potential candidate antigen for vaccine development.

Abstract
Objective: To evaluate the efficacy of endoscopic transnasal surgery for sinonasal and skull base adenoid cystic carcinoma (ACC), and to analyze the prognostic factors. Methods: Data of 82 patients (43 females and 39 males, at a median age of 49 years old) with sinonasal and skull base ACC who were admitted to XuanWu Hospital, Capital Medical University between June 2007 and June 2021 were analyzed retrospectively. The patients were staged according to American Joint Committee on Cancer (AJCC) 8th edition. The disease overall survival(OS) and disease-free survival(DFS) rates were calculated by Kaplan-Meier analysis. Cox regression model was used for multivariate prognostic analysis. Results: There were 4 patients with stage Ⅱ, 14 patients with stage Ⅲ, and 64 patients with stage Ⅳ. The treatment strategies included purely endoscopic surgery (n=42), endoscopic surgery plus radiotherapy (n=32) and endoscopic surgery plus radiochemotherapy (n=8). Followed up for 8 to 177 months, the 5-year OS and DFS rates was 63.0% and 51.6%, respectively. The 10-year OS and DFS rates was 51.2% and 31.8%, respectively. The multivariate Cox regression analysis showed that late T stage and internal carotid artery (ICA) involvement were the independent prognostic factors for survival in sinonasal and skull base ACC (all P<0.05). The OS of patients who received surgery or surgery plus radiotherapy was significantly higher than that of patients who received surgery plus radiochemotherapy (all P<0.05). Conclusions: Endoscopic transonasal surgery or combing with radiotherapy is an effective procedure for the treatment of sinonasal and skull base ACC. Late T stage and ICA involvement indicate poor prognosis.

Abstract
Objective: To analyse the genetic cause of a proband with mitochondrial disease caused by FASTKD2 gene variation and uniparental disomy. Methods: Detailed medical history of a child suspected "mitochondrial disease" were inquired in Peking University First Hospital on November 23, 2017. c.810_820dup homozygous variation in FASTKD2 gene was found by high-throughput sequencing, and her mother had heterozygous variation, but her father didn't have such variation, which didn't conform to the genetic law of variation. Further clinical examinations and molecular genetic tests were carried out. The venous blood of the child and her parents was drawn, and genomic DNA was extracted. Sanger sequencing, polymerase chain reaction (PCR) testing, short tandem repeat (STR) analysis, chromosome microarray analysis and loss of heterozygosity (LOH) genetic relationship analysis were performed on the proband and the parents to determine the variation. Results: The clinical manifestations, physical examination and laboratory examination of the child supported the diagnosis of mitochondrial disease. c.810_820dup(p.Ser274Phefs*8) homozygous variant in FASTKD2 gene was identified. Sanger sequencing indicated that the mother was a heterozygote of the variant, while the father had no such variation, which did not conform to the genetic law. PCR testing and Sanger sequencing review to eliminate sampling errors, PCR amplification and sequencing errors. Non-biological father was excluded by STR analysis. Three large segmental LOH of FASTKD2 gene were found by chromosome microarray analysis, then the LOH relative analysis verified the child was a mixed maternal uniparental disomy of chromosome 2. The child was diagnosed as mitochondrial disease caused by oxidative phosphorylation coupling defect of type 44. Conclusions: In this study, an autosomal recessive mitochondrial disease which does not conform to the genetic law was found, and it was confirmed that this mitochondrial disease family had both pathogenic variation and uniparental disomy phenomenon. It was diagnosed as mitochondrial disease caused by type 44 oxidative phosphorylation coupling defect.

Abstract
Objective: To analyze the survival and prognosis of Hodgkin lymphoma (HL) patients receiving standard first-line therapy. Methods: Data of clinical characteristics and treatment outcomes of patients with HL diagnosed in Cancer Hospital Chinese Academy of Medical Sciences (CHCAMS) from January 1st, 2000 to December 31st, 2018 who received standard first-line treatment were retrospectively analyzed and compared with that of HL patients who received treatment in the Surveillance, Epidemiology and End Results (SEER) database in the United States during the same period. Factors associated with freedom from progression (FFP) of patients in CHCAMS were analyzed. Treatment and survival data of patients with relapsed/refractory HL (r/rHL) who had failed the standard first-line treatment during the corresponding period in CHCAMS were collected to analyze the outcomes of salvage therapy. Results: A total of 764 HL patients in CHCAMS were included in this study. The median age was 30 years (range, 14-83 years), with 424 males and 340 females. By February 26th, 2022, the patients were followed-up for a median time of 111 months(range, 0.3-262.0 months). Lymphoma-specific survival (LSS) rate and overall survival (OS) rate at 10 years for HL patients in CHCAMS was 91.7% (95%CI: 89.5%-93.9%) and 87.1% (95%CI: 84.5%-89.8%), respectively. LSS and OS rate at 10 years for HL patients from SEER database was 86.8% (95%CI: 86.3%-87.2%) and 79.0% (95%CI: 78.5%-79.5%), respectively. The unadjusted LSS and OS rate for patients in CHCAMS were higher than those for patients from SEER database (both P<0.001). No significant difference was observed in LSS and OS rate (both P>0.05) between the two groups after adjustment. European Organization for Research and Treatment of Cancer staging system (early-stage unfavorable: HR=2.35, 95%CI: 1.13-4.89, P=0.023; advanced stage: HR=5.44, 95%CI: 2.62-11.30, P<0.001) and serum β2 microglobulin (HR=1.67, 95%CI: 1.08-2.58, P=0.021) were influencing factors of FFP for patients in CHCAMS. The complete remission rate, median progression-free survival (PFS), 5-year PFS rate and 5-year OS rate for the 116 patients with r/rHL was 37.9% (95%CI: 29.6%-47.0%), 15.0 months (95%CI: 9.9-20.1 months), 29.9% (95%CI: 20.9%-38.9%) and 62.9% (95%CI: 54.1%-71.7%), respectively. Conclusions: The outcomes of HL patients receiving standard first-line treatment are excellent. However, the therapeutic effect of HL patients who incurrs disease progression or relapse after standard first-line treatment is not satisfying.

Abstract
Objective: To summarize the clinical experience and treatment results of endoscopic transoral resection of metastatic retropharyngeal lymph nodes (MRPLN) in nasopharyngeal carcinoma (NPC) via posteroinferior eustachian tube approach. Methods: The clinical data of 37 patients with NPC who underwent endoscopic transoral surgery via posteroinferior eustachian tube approach for MRPLN in Xuanwu Hospital, Capital Medical University from 2010 to 2020 were analyzed retrospectively. There are 28 males and 9 females, aged from 31 to 72 years. The clinicopathological features such as gender, age, primary tumor stage, stage, side and size of MRPLN were recorded and analyzed. The surgical procedures of endoscopic transoral resection of MRPLN via posteroinferior eustachian tube approach were described. The MRPLN resection, perioperative complications and follow-up results were also summarized. Results: The primary tumors of 37 cases were determined as rT1 stage in 2 cases, rT2 stage in 30 cases and primary T2 stage in 5 cases in this study. There were 33 cases of unilateral MRPLN(89.2%), 4 cases of bilateral ones (10.8%), 36 cases in N1 stage, and 1 case in N3 stage. Single lymph node was detected in 23 cases(62.2%), and 2-5 lymph nodes in 14 cases(37.8%). Endoscopic transoral surgery via posteroinferior eustachian tube approach was completed in all cases. Total MRPLN resection was obtained in 35 cases (94.6%) with one-stage operation, and subtotal resection was achieved in 2 cases whose MRPLN involved the wall of internal carotid artery. No serious complications occurred in the perioperative period. During the follow-up period (median follow-up period 53.1 months), no recurrence of MRPLN was observed in patients who received total resection. And 8 patients (21.6%) died from different causes. Conclusion: Endoscopic transoral surgery via posteroinferior eustachian tube approach for MRPLN is a practicable and effective surgical option, but the long-term effect still needs longer follow-up and summary of bulk cases.

Abstract
Objective: To explore the long-term efficacy of low-dose rituximab (RTX) treatment in patients with primary membranous nephropathy (PMN). Methods: Patients with biopsy-proven PMN who received low-dose RTX as initial or second-line regimen from August 2018 to May 2020 in the Department of Nephrology, Tianjin Medical University General Hospital were respectively enrolled. The clinical parameters of patients were urinary protein>3.5 g/24 h, serum albumin<30 g/L and estimated glomerular filtration rate (eGFR)>20 ml·min-1·(1.73 m2)-1. The treatment response of patients with PMN was observed during follow-up, and the remission rate of patients with urinary protein<8 g/24 h or ≥8 g/24 h, anti-PLA2R antibody<150 RU/ml or ≥150 RU/ml, eGFR≥ 60 ml·min-1·(1.73 m2)-1 or<60 ml·min-1·(1.73 m2)-1 were analyzed, respectively. Results: A total of 40 patients were enrolled, including 26 males and 14 females, aged (53±15) years. There were 14 patients received RTX as initial treatment and 26 patients as second-line therapy. The total median dose of RTX in the first course was 800 (425, 1 075) mg. The overall remission rate at the 1st, 3rd, 6th, 12th and 24th months were 12.5% (5/40), 17.5% (7/40), 47.5% (19/40), 57.5% (23/40), 60% (24/40), respectively. The median overall response time was 6.0 (3.0, 7.5) months. Two cases relapsed. Patients with remission (n=24) had a higher level of baseline eGFR [(93.9±28.0) vs (62.4±28.1) ml·min-1·(1.73 m2)-1, P=0.001), and a lower level of both urinary protein [5.9 (5.0, 6.5) vs 11.7 (8.6, 15.5) g/24 h, P<0.001] and anti-PLA2R antibody level [73 (29, 132) vs 453 (182, 950) RU/ml, P=0.004] than those without remission (n=16) 24 month after treatment. There was no statistically significant difference in the remission rate between initial and second-line treatment (P=0.101). Moreover, patients had a higher remission rate in urinary protein<8 g/24 h group (21/26 vs 3/14, P<0.001), anti-PLA2R antibody<150 RU/ml group (16/19 vs 5/16, P=0.002) and eGFR ≥ 60 ml·min-1·(1.73 m2)-1 group (22/29 vs 2/11, P=0.003). Conclusions: Low-dose RTX treatment in PMN is effective during long-term follow-up, and has a lower recurrence rate. The results also suggest that it is more suitable for patients with baseline urinary protein<8 g/24 h, anti-PLA2R antibody<150 RU/ml and eGFR≥ 60 ml·min-1·(1.73 m2)-1.

Abstract
Abstract
Background
The persistence of health inequalities may not be merely driven by education and income, but also by other economic and non-economic factors. In this study we investigated how the association between single-dimensional health and socioeconomic status (SES) changes when including health-related person capital, economic capital, social capital, cultural capital and non-health related person capital.
Methods
The present study proposes a capital-based approach to understand health inequalities. It presumes intertwined relationships between a wide notion of health (‘health-related person capital’) and embodied resources (‘non-health related person capital’) on the one hand, and non-person capital, i.e. economic, social, and cultural resources on the other. We used cross-sectional data on 152,592 participants from the Dutch Lifelines cohort study. Correlations between capital constructs were estimated using partial least squares structural equation modelling.
Results
The correlation between health-related person capital and SES (r = 0.15) was higher than the correlations between single-dimensional health (physical and mental health) and SES (r = 0.12, r = 0.04, respectively). Non-person capital, combining economic, social and cultural capital, showed a correlation of 0.34 with health-related person capital. This was higher than the correlation between health-related person capital and economic capital alone (r = 0.19). Lastly, the correlation between health-related person capital and non-person capital increased when non-health (personality and attractiveness) and health related person capital were combined into person capital construct (from r = 0.34 to r = 0.49).
Conclusions
This exploratory observational study shows the empirical interconnectedness of various types of resources. Our findings corroborate the idea of considering health as a multidimensional concept, and to extend conventional SES indicators to a broader measurement of economic and non-economic resources.

Abstract
Formaldehyde detoxification is a process for converting tetanus toxin (TT) and diphtheria toxin (DT) into tetanus toxoid (TTd) and diphtheria toxoid (DTd), respectively. The mechanism of this detoxification process has been investigated by several previous studies based on lab-scale toxoids. To obtain greater insights of the effects induced by formaldehyde, industrial TTd and DTd batches obtained from different detoxification processes were studied in this work. Using liquid chromatography-mass spectrometry (LC-MS), 15 and 20 repeatable formaldehyde-induced modification sites of TTd and DTd were identified, respectively. Toxoid which had a higher formaldehyde-induced modification rate observed by LC-MS, also had larger bands on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Aggregates which were observed on size exclusion chromatogram (SEC) were confirmed by SDS-PAGE and LC-MS. Formaldehyde detoxification also led to a decrease of isoelectric point (pI) values and an increase of retention on weak anion exchange (WAX) column. Specific toxicity tests were conducted to evaluate toxicity of the TTd and DTd samples obtained with different detoxification conditions. Results from the specific toxicity tests showed that all toxoids used in this study were qualified, including toxoids obtained from mild and drastic detoxification conditions. However, obtained from mild detoxification conditions had less aggregates and may lead to a higher degree of glycosylation in conjugate vaccines than the ones obtained from drastic detoxification conditions. Thus, we suggest that mild detoxification conditions should be used to obtain TTd and DTd. Furthermore, as well as studying the formaldehyde-induced modifications and toxicity in TTd and DTd, the effects of the detoxification process on foreign proteins were also investigated. An increase in foreign proteins were observed in the aggregate than in the monomer of the toxoids. Additionally, some foreign proteins in the monomer of the toxins transferred to the aggregate of toxoids due to the formation of cross-linking. To eliminate the risk of cross-linking foreign proteins to toxoids in vaccination programs, a purification process is necessary before the detoxification process and/or the use of toxoids in vaccines.

Abstract
This study aimed to determine the apoptosis and autophagy-inducing mechanism of atractylodin in human breast cancer MCF-7 cells. The molecular mechanism of anticancer activity of atractylodin was confirmed by assessing the levels of reactive oxygen species (ROS) level, lipid peroxidation (LPO), antioxidants activity, dual staining, and comet assay. Moreover, cleaved caspases 3, 8, and 9, and signaling proteins, such as p53, Bcl-2, and Bax, phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin(P13K/Akt/mTOR), LC3I and LC3II, and beclin-1 were analyzed. In MCF-7 cells treated with atractylodin, the concentration-dependent toxicity, increased LPO, increased production of ROS, and decreased activity of superoxide dismutase, catalase, and glutathione peroxidasewere observed. In MCF-7 cells, atractylodin administration decreased Bcl-2 expression while activating the expression of p53, Bax, cleaved caspase-3, caspase-8, and caspase-9 apoptotic members. Furthermore, atractylodin blocked the P13K/Akt/mTOR signaling pathway, increased the conversion of LC3I to its lipidated form of LC3II, and increased beclin-1 expression, whereas downregulated the p62 expression in MCF-7 cells. As a result, altering apoptotic and autophagy-related biomarkers, atractylodin triggered apoptosis and autophagy in MCF-7 cells. As a result, atractylodin could be utilized to treat human breast cancer after the proper clinical trial.

Abstract
BACKGROUND AND PURPOSE CT is considered the standard reference both for quantification and characterization of carotid artery calcifications. Our aim was to investigate the relationship among different types of calcium configurations detected with CT within the plaque with a novel classification and to investigate the prevalence of cerebrovascular events. MATERIALS AND METHODS Seven hundred ninety patients (men = 332; mean age, 69.7 [SD, 13] years; 508 symptomatic for cerebrovascular symptoms and 282 asymptomatic) who underwent computed tomography of the carotid arteries were retrospectively included in this institutional review board-approved study. The plaque was classified into 6 types according to the different types of calcium configurations as the following: type 1, complete absence of calcification within the plaque; type 2, intimal or superficial calcifications; type 3, deep or bulky calcifications; type 4, adventitial calcifications with internal soft plaque of <2 mm thickness; type 5, mixed patterns with intimal and bulky calcifications; and type 6, positive rim sign. RESULTS The highest prevalence of cerebrovascular events was observed for type 6, for which 89 of the 99 cases were symptomatic. Type 6 plaque had the highest degree of correlation with TIA, stroke, symptoms, and ipsilateral infarct for both sides with a higher prevalence in younger patients. The frequency of symptoms observed by configuration type significantly differed between right and left plaques, with symptoms observed more frequently in type 6 calcification on the right side (50/53; 94%) than on the left side (39/46; 85%, P < .001). CONCLUSIONS We propose a novel carotid artery plaque configuration classification that is associated with the prevalence of cerebrovascular events. If confirmed in longitudinal analysis, this classification could be used to stratify the risk of occurrence of ischemic events.

Abstract
Background In this study, the combination of Eucommia ulmoides-Tribulus terrestris (EU-TT) was used to intervene in aging spontaneously hypertensive rats (SHRs). Quantitative proteomics sequencing was performed to screen the targets of EU-TT, so as to provide data support for the clinical application of EU-TT. Methods Eighteen-month-old SHRs were administered EU-TT (5.53 g/kg/day) intragastrically for 8 weeks. Blood pressure was recorded to evaluate the efficacy of EU-TT in vivo. Transmission electron microscopy (TEM) and hematoxylin-eosin (HE) staining were used to assess the morphology of the hypothalamus. The label free proteomics assay was performed to screen the targets of EU-TT in hypertensive hypothalami. ERK, JNK, and p38 were chosen for Reverse Transcription-quantitative Polymerase Chain Reaction (RT-qPCR) and Western blot. Results After 8 weeks of treatment, EU-TT effectively decreased systolic blood pressure (SBP) by 19.2 mmHg and diastolic blood pressure (DBP) by 8.6 mmHg (P<0.05), and improved the hypothalamus morphology of aging SHRs. Label free proteomics identified 248 differentially expressed (DE) proteins (157 were upregulated and 91 were downregulated) in the hypothalamus after EU-TT treatment. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis suggested that EU-TT regulated the MAPK signal transduction pathway, which was also confirmed by RT-qPCR and Western blot. Conclusions EU-TT steadily decreased the SBP and DBP of aging SHRs, and improved the morphology of the hypothalamus, which was pharmacologically related to the MAPK signaling pathway. Keywords Aging spontaneously hypertensive rats (SHRs); Eucommia ulmoides-Tribulus terrestris (EU-TT); hypothalamus; label free proteomics; MAPK signaling pathway

Abstract
Phase modulators based upon the thermo-optic effect are used widely in silicon photonics for low speed applications such as switching and tuning. The dissipation of the heat produced to drive the device to the surrounding silicon is a concern as it can dictate how compact and tightly packed components can be without concerns over thermal crosstalk. In this paper we study through modelling and experiment, on various silicon on insulator photonic platforms, how close waveguides can be placed together without significant thermal crosstalk from adjacent devices.

Abstract
OBJECTIVE To evaluate the diagnostic efficacy of technetium-99m methoxyisobutylisonitrile single photon emission/ computed tomography (99mTc- MIBI SPECT/CT), 99mTc- MIBI double- phase scintigraphy (DPS) DPS and ultrasound (US) in preoperative localization of hyperparathyroidism (HPT) and explore the factors affecting the diagnostic efficacy of 99mTc-MIBI SPECT/CT. METHODS We retrospectively analyzed the data of 104 patients with HPT undergoing surgical resection between January, 2015 and July, 2019. Preoperative 99mTc-MIBI imaging was performed in all the patients, and 82 patients also received US examination preoperatively. Semi-quantitative analysis was used to draw the region of interest and calculate the lesion/ ipsilateral deltoid muscle (T/NT) uptake ratio. The sensitivity and detection performance of 99mTc-MIBI SPECT/CT, DPS and US in the diagnosis of HPT patients were compared, and the correlations of the T/NT ratios of parathyroid adenoma (PA) and parathyroid hyperplasia (PH) with the expression levels of COX-2 and Bcl-2 were analyzed. RESULTS The diagnostic sensitivity of 99mTc- MIBI SPECT/CT, DPS and US for HPT was 95.19% (99/104), 91.3% (95/104) and 81.71% (67/82), respectively, demonstrating a significantly higher diagnostic sensitivity of 99mTc-MIBI SPECT/CT than US (χ2=9.59, P=0.008). For PH lesions, 99mTc-MIBI SPECT/CT had the highest diagnostic sensitivity, followed by DPS and then by US (P < 0.05), but their sensitivity did not differ significantly for PA (P>0.05). The T/NT ratio in fatty hyperplastic glands was significantly lower than that in fat-free hyperplastic glands (P=0.009). In PA, Bcl-2 expression was significantly lower in false negative lesions than in true positive lesions (P=0.046), but Cox-2 expression did not show such a difference (P>0.05). In PH lesions, the expressions of Bcl-2 and Cox- 2 did not differ significantly between false negative than true positive lesions (P>0.05). CONCLUSIONS 99mTc-MIBI SPECT/CT has a high sensitivity for HPT localization, and the T/NT ratio is positively correlated with the lesion volume. An increased expression of Bcl-2 in PA lesions and a decreased cell fat content in PH lesions can facilitate the detection of HPT glands by 99mTc-MIBI SPECT/CT.

Abstract
Prolonged and severe hypoxia is the main cause of death of transplanted cells prior to the establishment of functional circulation. In situ generation of oxygen by oxygen-producing scaffolds-a unique solution that could produce and deliver oxygen to the adjacent cells independently of blood perfusion-has attracted considerable attention to enhance the survivability of the transplanted cells. However, the application of oxygen-generating scaffolds for facilitating cell survival in pulp-like tissue regeneration is yet to be explored. In this study, gelatin methacryloyl (GelMA)-a biocompatible scaffolding material that closely mimics the native extracellular matrix and is conducive to cell proliferation and differentiation-was used to fabricate oxygen-generating scaffolds by loading various concentrations of CaO2. The CaO2 distribution, topography, swelling, and pore size of CaO2-GelMA hydrogels were characterized in detail. The release of O2 by the scaffold and the viability, spreading, and proliferation of stem cells from apical papilla (SCAPs) encapsulated in the GelMA hydrogels with various concentrations of CaO2 under hypoxia were evaluated. In addition, cellular constructs were engineered into root canals, and cell viability within the apical, middle, and coronal portions was assessed. Our findings showed that 0.5% CaO2-GelMA was sufficient to supply in situ oxygen for maintaining the embedded SCAP viability for 1 wk. Furthermore, the 0.5% CaO2-GelMA hydrogels improved the survivability of SCAPs within the coronal portion of the engineered cellular constructs within the root canals. This work demonstrated that 0.5% CaO2-GelMA hydrogels offer a potential promising scaffold that enhances survival of the embedded SCAPs in endodontic regeneration.

Abstract
OBJECTIVE To analyze single-photon emission tomography (SPECT) images of cerebral blood flow perfusion using an easy Z-score imaging system (eZIS) and explore the value of SPECT and eZIS in early diagnosis of Alzheimer's disease (AD). METHODS We retrospectively analyzed the clinical data of 71 subjects undergoing brain perfusion SPECT examination in our department from September, 2018 to September, 2020 and identified 31 eligible subjects for this study. Among these subjects, according to the NIA-AA criteria (2011 edition), 12 were diagnosed with mild cognitive impairment due to AD (MCI) and 11 with AD dementia stage (AD); 8 elderly subjects were healthy without cognitive impairment (NC). All these subjects underwent brain perfusion SPECT, and eZIS-assisted analysis was used to obtain the index values (severity, range and ratio). The differences in the severity, extent and ratio among the 3 groups were compared, and the diagnostic efficacy of single and joint analysis of the 3 indexes for early AD was analyzed. RESULTS There was no significant difference in gender, age and education level among the 3 groups (P>0.05). Compared with those in NC group, the Mini Mental State Examination Scale (MMSE) scores were significantly lowered in AD group and MCI group; the MMSE score was significantly lower in AD group than in MCI group (P < 0.05). The patients with AD had significantly greater disease severity and extent than those with MCI group; the severity, range and ratio in both AD group and MCI group were significantly higher than those of NC group, but the ratio did not differ significantly between AD group and MCI group (P>0.05). In single index analysis, severity had the highest diagnostic performance (AUC=0.911) and sensitivity (87.0%); the diagnostic performance and sensitivity of joint analysis were better than those of single analysis, and joint analysis of range and ratio showed high diagnostic performance (AUC=0.948) and sensitivity (87.0%). CONCLUSION The analysis of brain perfusion SPECT using an eZIS program can be useful for early diagnosis of AD.

Abstract
Objective: To summarize the clinical and pathological features of intravascular NK and T cell lymphoma for better understanding of such disease to reduce misdiagnosis and miss-diagnosis. Methods: Clinical and pathological features were analyzed retrospectively in one case of intravascular peripheral T-cell lymphoma, not otherwise specified (IVPTCL, NOS) , with literatures review. Results: The case presented in this study was a 66-year-old man. PET/CT scan showed multiple lymph nodes enlargement throughout the body. Normal lymph node structure could not be observed by tissue biopsy, while lymph follicles were partially disrupted. High-power light microscope revealed a large number of blood vessels with diffuse proliferation and dilation, where atypical lymphoid cell mass was restricted in the lumen and partially infiltrated the large blood vessel wall. These tumor cells were medium to large with moderate cytoplasm. The nucleus was irregular, single or multiple nucleoli could be seen, chromatin was condensed, some were empty and bright, and mitotic figures could be seen. Immunohistochemical staining showed that the neoplastic cells were positive for expression of CD3, CD43, CD8, GrB, TIA-1 and perforin. EBER in situ hybridization result was negative. Polymerase chain reaction test identified a clonal gene rearrangement of T-cell receptor γ. The patient was treated with CHOP in combination with chidamide, but died of infection and cardiopulmonary failure within 2 months. 56 cases of intravascular NK/T cell lymphoma with definite classification were collected from relevant literatures, including 47 cases with nasal type of extranodal NK/T cell lymphoma (27 were male and 20 were female) , 8 cases with anaplastic large cell lymphoma (3 males and 5 females) , and only one case with de nova IVPTCL, NOS in brain. We report the second case of IVPTCL,NOS, and notably originated from lymph node for the first time. Conclusions: Intravascular NK/T cell lymphoma is a highly aggressive disease with no effective treatment at present. Involvement of Lymph node has rarely been reported, and further studies on more cases are necessary.

Abstract
Dioscin, one natural product, has various pharmacological actions. However, its effects on methotrexate (MTX)-induced hepatorenal damages still remain unknown. In the present study, the data manifested that dioscin restored the viabilities of L-02 and NRK-52E cells, reduced ALT, AST, Cr, BUN levels, and ameliorated histopathological changes of liver and kidney. Besides, dioscin decreased ROS levels in cells, and adjusted SOD, MDA, GSH and GSH-Px levels in rats. Dioscin reduced the expression levels of miR-145-5p which directly targeted Sirt5, and then regulated the expression levels of SOD1, Nrf2, Gst, Keap1, HO-1, GCLC and NQO1. MiR-145-5p mimic in cells deteriorated ROS levels and decreased Sirt5 expression to accentuate oxidative stress by regulating the expression levels of SOD1, Nrf2, Keap1, which were all reversed by dioscin. Moreover, MTX-induced hepatorenal damage were worsened in mice by Sirt5 siRNA or miR-145-5p agomir, which were also alleviated by dioscin. Dioscin relieved MTX-induced hepatorenal damages through regulating miR-145-5p-medicated oxidative stress, which should be considered as one effective drug to treat the disorder in future.

Abstract
OBJECTIVES High-risk human papillomavirus (HR-HPV) is an important risk factor for esophageal cancer. Macrophages constitute a crucial immune medium for regulating HPV-related tumors; however, the specific regulatory mechanisms remain unknown. Therefore, the purpose of our current study was to investigate the mechanism by which HPV16E6 regulates macrophages to promote the invasion and metastasis of esophageal cancer. METHODS HPV16E6 infection was detected by polymerase chain reaction. Immunohistochemistry was used to verify the distribution of tumor-associated macrophages (TAMs) and MMP-9 expression in esophageal squamous cell carcinoma tissues (ESCCs), and cancer adjacent normal tissues (CANs) from Kazakh patients. ESCC cells were transfected with a plasmid over-expressing HPV16E6 and non-contact cocultured with macrophages. RESULTS The infection rate of HPV16E6 in Kazakh ESCCs was clearly higher than that in CANs (P < 0.05). The density of CD163-positive TAMs was significantly positively correlated with HPV16E6 infection in ESCCs (P < 0.05). After coculturing macrophages and EC9706 cells transfected with the HPV16E6 plasmid, the phenotype of macrophages transformed into M2 macrophages. The migration and invasion ability of ESCC cells were higher in the HPV16E6-transfected and coculture group than in the HPV16E6 empty vector-transfected and non-cocultured HPV16E6-transfected groups (all P < 0.05). The density of M2-like TAMs in ESCCs was positively correlated with the level of MMP-9 expression. MMP-9 expression in the HPV16E6-ESCC coculture macrophages group was substantially higher than that in controls (all P < 0.05). CONCLUSIONS HPV16 infection mediates tumor-associated macrophages to promote ESCC invasion and migration.

Abstract
Objective: To investigate the role of microRNA-139-5p (miR-139-5p) in the occurrence and development of esophageal squamous cell carcinoma (ESCC) and its effects on cell proliferation and invasion of ESCC cells and its molecular mechanisms. Methods: Seventy-five cases of ESCC tissues and paired normal tissues were obtained from thoracic surgery of the First Affiliated Hospital of Zhengzhou University from February 2017 to March 2018. Experiment was divided into two group: ESCC (n=75) and normal esophageal tissues (n=75).GEO datasets and real-time quantitative PCR (qRT-PCR) were used to detect the expression of miR-139-5p in ESCC tissues and cells. miR-139-5p inhibitor, miR-139-5p mimic, negative control, control siRNA, T-box transcliption factor 1(TBX1) siRNA, pcDNA3.1 and pcDNA3.1-TBX1 were transfected into ESCC Eca109 and TE1 cells. qRT-PCR was used to detect the expressions of miR-139-5p and TBX1 in transfected ESCC cells. Cell counting kit 8 (CCK-8) and Transwell chamber were employed to detect cell proliferation and invasion of ESCC cells, respectively. Dual-Luciferase Reporter assay was used to analyze the interaction between miR-139-5p with TBX1. qRT-PCR, Western blot and immunohistochemistry were utilized to detect the expression of TBX1 in ESCC tissues. Western blot was used to detect the expressions of E-cadherin, N-cadherin and Vimentin after transfection. Results: The level of miR-139-5p in ESCC tissues was significantly lower than that in normal tissues (1.17±0.43 vs 5.16±3.62,P<0.001). Log-rank test showed that the survival rate of ESCC patients with high miR-139-5p level (n = 43) was significantly higher than that with low miR-139-5p level (n=32) (67.44% vs 25.00%, P = 0.005). The expression level of miR-139-5p in ESCC cells was significantly lower than that of normal esophageal epithelial cell Het-1A (all P<0.001). The proliferation and invasion ability of ECA109 and TE1 cells with high expression of miR-139-5p were significantly lower than those transfected with negative control (NC) (all P<0.05). Dual-Luciferase Reporter assay showed that miR-139-5p could bind to the 3'-untranslated region of TBX1. miR-139-5p mimic or inhibitor suppressed or promoted the expression of TBX1 protein in Eca109 and TE1 cells, respectively (all P<0.05). Downregulation of TBX1 significantly suppressed proliferation and invasion of ECA109 and TE1 cells, while overexpression of TBX1 significantly promoted proliferation and invasion of ECA109 and TE1 cells (all P<0.05). In addition, pcDNA3.1-TBX1 partially reversed the inhibition of miR-139-5p-mediated invasion ability (all P<0.05), while TBX1 siRNA partially reversed the enhancement of miR-139-5p inhibitor-mediated invasion ability (all P<0.05). Conclusion: miR-139-5p suppressed ESCC cell proliferation and invasion by targeting TBX1.

Abstract
AIM To review the removal of Y-shaped airway self-expanding covered metallic stents using the interventional technique under fluoroscopy. MATERIALS AND METHODS The clinical data of 33 patients who underwent removal of Y-shaped airway self-expanding covered metallic stents from March 2011 to August 2019 were analysed retrospectively. RESULTS A total of 35 Y-shaped stents were removed. The average indwelling duration of the tracheal stents was 101.7 ± 105.4 days. Four cases were removed via the conventional method (grasping the upper tip of the stent to collapse and adduct the proximal end of the stent), whereas 31 cases were removed using the reversal method (grasping the distal end of the stent to invert and strip out the stent). The duration of stent removal was 24.3 ± 12.4 minutes (median time, 20 minutes). CONCLUSION The interventional radiology technique is a feasible, safe, and effective method for removing Y-shaped airway self-expanding covered metallic stents, and can be considered for use in the clinical setting.

Abstract
Objective: To study the value of chromosome microarray analysis (CMA) application in children with developmental delay (DD), intellectual disability (ID), autistic spectrum disorder (ASD) and multiple congenital anomalies (MCA). Methods: Genomic DNA was extracted from peripheral blood samples. Array-based comparative genomic hybridization (array-CGH) analysis and single nucleotide polymorphism array (SNP-array) were performed in 1 320 children with DD/ID, ASD, with or without epilepsy and MCA who were admitted to Peking University First Hospital from 2014 to 2019. The results of genetic etiology test of CMA in children with mental retardation or global DD was summarized. Results: Of 1 320 samples, there were 10 cases of aneuploid abnormality, 6 cases of uniparental disomy and one case of mosaicism, respectively. Pathogenic copy number variations (CNVs) were found in 320 cases and pathogenic CNVs were detected in 23 cases, with a combined detection rate of 26% (343/1 320). CNVs of uncertain clinical significance occurred in 107 cases, accounting for 8.1% (107/1 320). There were 25 cases of possible benign CNVs, accounting for 2% (25/1 320), while benign CNVs were reported in 20 cases, accounting for 1.5% (20/1 320). The detection rate of MCA with DD/ID was 39.8% (130/327). Conclusions: CMA has the advantages of high resolution and covering the whole genome. It can detect the chromosomal abnormalities, microdeletions and duplications seen under the microscope, thus the genetic etiology of children with mental retardation or global DD can be diagnosed.

Abstract
The pathogenesis of hepatic encephalopathy (HE) has been generally linked to blood ammonia, gamma-aminobutyric acid and serotonin. However, the exact mechanism remains unclear. In the present study, we aimed to explore the role of hippocampal dopamine (DA) and its receptors in the pathogenesis of HE through the use of behavioral testing, western blotting, and immunofluorescence staining in normal rats, HE model rats and rats treated with the DA precursor-levodopa (L-DOPA). HE model rats manifested fibrotic livers and showed serious behavioral disorders. They also had significantly lower hippocampal DA content and increased expression of both D1 and D2 receptors relative to normal rats. After treatment with L-DOPA, the HE model rats showed normal behavior and expression of D1 returned to normal levels. Furthermore, pretreatment with the D1 antagonist SCH23390 blocked the therapeutic effect of L-DOPA on behavior in HE model rats. Taken together, these results clarify that the decrease in hippocampal DA plays a role in the pathogenesis of HE and that this effect is mediated by D1. These findings provide new evidence for the pathogenesis of HE.

Abstract
OBJECTIVE To explore the correlation between interleukin (IL)-33 gene polymorphism with chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS A total of 210 COPD patients (observation group) and 180 healthy people receiving physical examinations (control group) were included in this study. Clinical information of each subject was collected. Relative levels of inflammation-related factor IL-33 and pulmonary function indexes were determined. Moreover, the polymorphism of IL-33 rs1891385 was detected with the TaqMan-minor groove binder (MGB) probe. RESULTS Observation group had a higher level of IL-33 than that of control group (p<0.01), and the forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) ratio (%) and FEV1/the predicted value ratio (%) in observation group were lower than those in control group (p<0.05). There were significant differences in the distribution frequencies of genotypes and alleles between the two groups (p<0.05), and genotype AA exhibited a higher level of IL-33, but a lower FEV1/FVC ratio (%) and FEV1/the predicted value ratio (%) than those of genotypes AC and CC (p<0.05). CONCLUSIONS IL-33 and pulmonary function test can be used to effectively evaluate the progression of COPD, and the polymorphism of IL-33 rs1891385 is correlated with the onset of COPD.

Abstract
Objective: To investigate the effects of thoracoscopy-guided thoracic paravertebral block for analgesia after single-port video-assisted pulmonary lobectomy. Methods: From December 2019 to April 2020, 60 patients receiving single-port video-assisted pulmonary lobectomy at Ningbo Medical Center Lihuili Hospital were selected. The patients were randomly and equally divided into control group and paravertebral block group using a random number table. Patients of paravertebral block group were injected into the thoracic 4-5 intercostal, paravertebral 1 cm using 0.375% ropivacaine (20 ml) with thoracoscopy-guided at the end of surgery, while patients of control group were given patient controlled intravenous analgesia (PCIA). Postoperative visual analogue scale (VAS) and Ramsay sedation scale were recorded at 6, 12, 24, 36, 48 h after the surgery. The incidence of postoperative adverse reactions, additional dose and times of pethidine, the time to resume eating, the rate of postoperative active cough, the first time to get out of bed after surgery and postoperative hospital stay of two groups' patients were recorded. t test and chisquare test were used for statistical analysis. Results: The VAS score of paravertebral block group were lower than those of control group at all time points (all P<0.05). The Ramsay sedation scale of paravertebral block group were higher than those of control group at all time points (all P<0.05). The additional dose and times of pethidine of paravertebral block group were (8.2±2.3) mg and (0.2±0.1) time, which were lower than (87.8±15.3) mg and (1.8±0.3) time of control group, the differences were statistically significant (t=28.91, 34.37, all P<0.05). Incidence of nausea, vomiting and pruritus of paravertebral block group were 10.0%, 6.7% and 0, which were lower than 40.0%, 30.0% and 13.3% of control group, the differences were statistically significant (χ(2)=7.20, 5.45, 4.29, all P<0.05). The rate of postoperative active cough of paravertebral block group was 33.3%, which was higher than 10.0% of control group, the difference was statistically significant (χ(2)=4.81, P<0.05). The time to resume eating, the first time to get out of bed after surgery and postoperative hospital stay were (6.5±0.4) h, (20.9±3.1) h and (4.6±1.0) d, which were lower than (8.5±0.7) h, (28.6±4.8) h and (6.1±1.3) d of control group, the differences were statistically significant (t=13.47, 7.39, 4.19, all P<0.05). Conclusion: Thoracic paravertebral block under thoracoscopy-guided can effectively reduce the postoperative pain of single-port thoracoscopic lobectomy, with fewer adverse reactions, and is beneficial to postoperative recovery.

Abstract
Cardiometabolic diseases are characterized as a combination of multiple risk factors for cardiovascular disease (CVD) and metabolic diseases including diabetes mellitus and dyslipidemia. Cardiometabolic diseases are closely associated with cell glucose and lipid metabolism, inflammatory response and mitochondrial function. Farnesoid X Receptor (FXR), a metabolic nuclear receptor, are found to be activated by primary BAs such as chenodeoxycholic acid (CDCA), cholic acid (CA) and synthetic agonists such as obeticholic acid (OCA). FXR plays crucial roles in regulating cholesterol homeostasis, lipid metabolism, glucose metabolism, and intestinal microorganism. Recently, emerging evidence suggests that FXR agonists are functional for metabolic syndrome and cardiovascular diseases and are considered as a potential therapeutic agent. This review will discuss the pathological mechanism of cardiometabolic disease and reviews the potential mechanisms of FXR agonists in the treatment of cardiometabolic disease.

Abstract
MiR-23a-5p is involved in the occurrence and development of some serious diseases, but its effects on intestinal ischemia-reperfusion (II/R) injury is unclear. In this research, the hypoxia/reoxygenation (H/R) model on IEC-6 cells and II/R model in mice were used. The data showed that the ROS level in model group was significantly increased compared with control group. The level of intestinal MPO was increased and serum SOD was decreased in mice compared with sham group. Moreover, the expression levels of miR-23a-5p in model groups were obviously increased in vitro and in vivo, while the expression levels of PPARα, FOXO3α, PGC-1α, Nrf2, CAT, NQO1, HO-1 and SOD2 were significantly decreased. The double luciferase reporter gene assay showed that there was binding site between miR-23a-5p and PPARα. When miR-23a-5p was inhibited or PPARα gene was overexpressed, H/R-caused cell damage was alleviated and ROS level was decreased compared with NC group. PPARα expression level was increased, accompanied by the increased levels of FOXO3α, PGC-1α, Nrf2, CAT, NQO1, HO-1 and SOD2. After enhancing miR-23a-5p expression or silencing PPARα gene, H/R-caused cell damage was further aggravated compared with NC group, and ROS level was increased associated with the decreased levels of FOXO3α, PGC-1α, Nrf2, CAT, NQO1, HO-1 and SOD2. Our study demonstrated that miR-23a-5p exacerbated II/R injury by promoting oxidative stress via targeting PPARα, which should be considered as one new drug target to treat II/R injury.

Abstract
BACKGROUND AND PURPOSE Inflammatory changes in the fat tissue surrounding the coronary arteries have been associated with coronary artery disease and high-risk vulnerable plaques. Our aim was to investigate possible correlations between the presence and degree of perivascular fat density and a marker of vulnerable carotid plaque, namely contrast plaque enhancement on CTA. MATERIALS AND METHODS One-hundred patients (76 men, 24 women; mean age, 69 years) who underwent CT angiography for investigation of carotid artery stenosis were retrospectively analyzed. Contrast plaque enhancement and perivascular fat density were measured in 100 carotid arteries, and values were stratified according to symptomatic (ipsilateral-to-cerebrovascular symptoms)/asymptomatic status (carotid artery with the most severe degree of stenosis). Correlation coefficients (Pearson ρ product moment) were calculated between the contrast plaque enhancement and perivascular fat density. The differences among the correlation ρ values were calculated using the Fisher r-to-z transformation. Mann-Whitney analysis was also calculated to test differences between the groups. RESULTS There was a statistically significant positive correlation between contrast plaque enhancement and perivascular fat density (ρ value = 0.6582, P value = .001). The correlation was stronger for symptomatic rather than asymptomatic patients (ρ value = 0.7052, P value = .001 versus ρ value = 0.4092, P value = .001). CONCLUSIONS There was a positive association between perivascular fat density and contrast plaque enhancement on CTA. This correlation was stronger for symptomatic rather than asymptomatic patients. Our results suggest that perivascular fat density could be used as an indirect marker of plaque instability.

Abstract
The structure of a decagonal quasicrystal in the Zn58Mg40Y2 (at.%) alloy was studied using electron diffraction and atomic resolution Z-contrast imaging techniques. This stable Frank-Kasper Zn-Mg-Y decagonal quasicrystal has an atomic structure which can be modeled with a rhombic/hexagonal tiling decorated with icosahedral units at each vertex. No perfect decagonal clusters were observed in the Zn-Mg-Y decagonal quasicrystal, which differs from the Zn-Mg-Dy decagonal crystal with the same space group P10/mmm. Y atoms occupy the center of 'dented decagon' motifs consisting of three fat rhombic and two flattened hexagonal tiles. About 75% of fat rhombic tiles are arranged in groups of five forming star motifs, while the others connect with each other in a 'zigzag' configuration. This decagonal quasicrystal has a composition of Zn68.3Mg29.1Y2.6 (at.%) with a valence electron concentration (e/a) of about 2.03, which is in accord with the Hume-Rothery criterion for the formation of the Zn-based quasicrystal phase (e/a = 2.0-2.15).

Abstract
Small-animal imaging is an essential tool that provides noninvasive, longitudinal insight into novel cancer therapies. However, considerable variability in image analysis techniques can lead to inconsistent results. We have developed quantitative imaging for application in the preclinical arm of a coclinical trial by using a genetically engineered mouse model of soft tissue sarcoma. Magnetic resonance imaging (MRI) images were acquired 1 day before and 1 week after radiation therapy. After the second MRI, the primary tumor was surgically removed by amputating the tumor-bearing hind limb, and mice were followed for up to 6 months. An automatic analysis pipeline was used for multicontrast MRI data using a convolutional neural network for tumor segmentation followed by radiomics analysis. We then calculated radiomics features for the tumor, the peritumoral area, and the 2 combined. The first radiomics analysis focused on features most indicative of radiation therapy effects; the second radiomics analysis looked for features that might predict primary tumor recurrence. The segmentation results indicated that Dice scores were similar when using multicontrast versus single T2-weighted data (0.863 vs 0.861). One week post RT, larger tumor volumes were measured, and radiomics analysis showed greater heterogeneity. In the tumor and peritumoral area, radiomics features were predictive of primary tumor recurrence (AUC: 0.79). We have created an image processing pipeline for high-throughput, reduced-bias segmentation of multiparametric tumor MRI data and radiomics analysis, to better our understanding of preclinical imaging and the insights it provides when studying new cancer therapies.
