Abstract
Objective: We evaluated the safety and efficacy of lipoprotein apheresis (LA) in patients with familial hypercholesterolemia (FH) who can't reach low-density lipoprotein cholesterol(LDL-C) target goals with the maximal tolerated dose of lipid-lowering agents. Methods: This was a retrospective cross-sectional study. Between February 2015 and November 2019, patients with FH who were admitted in Fuwai hospital and treated with LA were consecutively enrolled. Based on intensive lipid-lowering agents, these patients received LA by double filtration plasma pheresis (DFPP) method. The changes of lipid levels such as LDL-C and lipoprotein(a)[Lp(a)] were compared before and after LA treatment, and the changes of immunoglobulin (Ig) concentration and LA-related adverse effects were also discussed. Results: A total of 115 patients with FH were enrolled in this study, of which 8 cases were homozygous FH and 107 cases were heterozygous FH. The age was (43.9±12.2) years and there were 75 (65.2%) males, and 108 (93.8%) with coronary artery disease. For pre-and immediately after LA treatment, the LDL-C was (5.20±2.94) mmol/L vs. (1.83±1.08) mmol/L, Lp(a) concentration was 428.70(177.00, 829.50)mg/L vs. 148.90(75.90, 317.00) mg/L (P<0.001), with a decrease of 64.2% and 59.8% respectively. The levels of IgG and IgA measured 1 day after LA treatment were both in the normal range and IgM concentration was below the reference value, the reductions of which were 15.1%, 25.0% and 58.7% respectively (P<0.001). Six patients had mild symptoms of nausea, hypotension dyspnea and palpitation, the symptoms were relieved by symptomatic treatment. Conclusion: For patients with FH who do not achieve LDL-C target goal with the maximal tolerated lipid-lowering agents, especially those with elevated Lp(a) levels, LA, which can significantly further reduce LDL-C and Lp(a) levels, is an effective and safe option.

Abstract
Studies have shown that autoimmune disease (AID)-related ulcers are disease complications that lead to serious poor prognosis such as infection and disability. It is difficult to make a clear diagnosis and there are contradictions between the applications of immunosuppressive therapy and anti-infectious therapy. Improper diagnosis and immunosuppressive therapy can easily delay the timing of anti-infectious therapy and surgery for patients, which bring adverse effects on the prognosis of patients. This paper reviews the concept, clinical characteristics and treatment suggestions of each subtype of AID-related ulcers, in order to provide more ideas for AID-related ulcers' clinical diagnosis and treatment.

Abstract
BackgroundA phase 4 trial (NCT04087720) of kidney transplant (KT) recipients on stable immunosuppressants with uncontrolled gout previously reported that pegloticase produced a sustained decrease in serum uric acid (sUA) levels and was associated with clinically meaningful improvements in pain and disability without worsening of key kidney function markers. Pegloticase treatment was well tolerated overall with no infusion reactions or anaphylaxis. Here we report additional exploratory and secondary endpoints.ObjectivesTo evaluate the results of clinically important efficacy endpoints as supportive evidence for the efficacy of pegloticase in kidney transplant patients on immunosuppression.MethodsPROTECT a multicenter, open-label, efficacy and safety study of pegloticase in included kidney transplant recipients (KT>1 year prior) with uncontrolled gout (sUA ≥7 mg/dL, oral urate lowering therapy contraindication/inefficacy, and with either visible tophi, chronic gouty arthritis, or ≥2 flares in past year), who had a functioning graft (estimated glomerular filtration rate [eGFR] ≥15 ml/min/1.73m2), and were on a stable immunosuppressant regimen. Pegloticase (8 mg infusion) was administered biweekly for 24 weeks (12 infusions) followed by a final follow up visit 3 months post-treatment. The global health component of the Health Assessment Questionnaire (HAQ-Health), and the physician global assessment of gout (PGA) were assessed at baseline, weeks 6, 14, 20, 24, and the end of pegloticase infusions (EOI) visit (if applicable, when the final infusion occurred prior to week 22). Both were visual analog scales (VAS), where HAQ-health ranged from 0 (very well) to 100 (very poor) and PGA ranged from 0 (excellent) to 10 (very poor). Heart rate and blood pressure measurements were recorded at baseline, weeks 6, 12, 18, 24 and the EOI visit.Results20 patients received at least 1 dose of pegloticase and were included in the analysis with the majority (90.0%) 40 to 81 years of age. Most were male (85.0%), 45.0% white, and 35.0% black or African American. Median body weight (88.46 kg) and body mass index (29.68 kg/m2) were high. Median baseline eGFR and baseline Urine Albumin-Creatinine Ratio (UACR) were 41.70 mL/min/1.73m2 and 312.00 mg/g, respectively. An improvement from baseline to weeks 14 (n=18), and 24 (n=15 [PGA], n=14 [HAQ]) in mean PGA and HAQ-Health was observed. Change from baseline (Mean [SD]) at 14 and 24 weeks for PGA was -2.3 (1.94) and -2.3 (2.19), and for HAQ-Health was -32.74 (21.26) and -21.52 (27.47) respectively. Improvement was sustained at the 3-month post-treatment follow-up visit. Mean decreases from baseline in sitting systolic blood pressure, diastolic blood pressure, and mean arterial pressure were observed at weeks 6, 12, 18 and 24. Change from baseline values at 24 weeks (n=15) for systolic, diastolic and mean arterial pressures were (Mean [SD]) -11.01 (14.04), -4.37 (9.18), and -6.58 (9.675) mmHg respectively. Heart rate showed no clinically meaningful trends from baseline at any of the post-baseline timepoints.ConclusionClinically important improvements in both HAQ and PGA were demonstrated for pegloticase treated kidney transplant patients. Improvements were also observed in systolic, diastolic, and mean arterial blood pressure. These data support the benefits of pegloticase treatment for uncontrolled gout in kidney transplant recipients using immunosuppression.Disclosure of InterestsAbdul Abdellatif Speakers bureau: Amgen, Aurinia, Bayer, Horizon, Janssen, Keryx, Mallinckrodt, Merck, Natera, Opko, Rockwell and Vifor Pharma, Consultant of: Amgen, Horizon, Keryx Mallinckrodt, Opko, Pharmacosmos, and Rockwell, Lin Zhao Shareholder of: Horizon Therapeutics, Employee of: Horizon Therapeutics, Katya Cherny Shareholder of: Horizon Therapeutics, Employee of: Horizon Therapeutics, Brad Marder Shareholder of: Horizon Therapeutics, Employee of: Horizon Therapeutics, John Scandling Consultant of: Horizon Therapeutics, Kenneth Saag Grant/research support from: Horizon Therapeutics, SOBI and Shanton

Abstract
Objective: To evaluate the effect of "Smoking cessation: Doctor first" program on smoking medical staff. Methods: From December 2016 to September 2019, 1 747 smoking medical staff from 54 units of China Tobacco Cessation Alliance were enrolled into"Smoking cessation: Doctor first"program. Demographic characteristics, smoking characteristics, degree of tobacco dependence, willingness to quit smoking and other related factors were collected during the baseline survey. Multivariate logistic regression model was used to analyze the related factors of willingness to quit. The subjects were given intensive smoking cessation intervention from October 2017 to September 2019, including education on the hazards of smoking, methods of smoking cessation and giving smoking cessation drugs. After intervention, the subjects were investigated about their smoking cessation progress and the effect of the project was evaluated. Results: The subjects were (41±11) years old, 91.9% (1 609/1 747) were male and 62.2% (1 086/1 747) were daily smokers. The main reasons for smoking included the influence of friends [697 (39.9%)], the need for social entertainment [629 (36.0%)], the relief of mental stress [589 (33.7%)] and the refreshment [459 (26.3%)]. At baseline, 52.9% (885/1 672) and 43.2% (755/1 747) smokers had intention to quit smoking and had planned to quit within one year, respectively. Multivariate logistic regression model analysis showed that: low education level [OR (95%CI) of high school and junior high school and below were 2.42 (1.61, 3.63) and 1.57 (1.18, 2.11)], daily smoking [OR (95%CI): 1.38 (1.06, 1.78)], thinking quitting smoking is not important [OR (95%CI): 4.15 (3.33, 5.18)] and having no quitting experience [OR (95%CI): 3.21 (2.53, 4.05)] were associated with no intention to quit smoking. After intensive smoking cessation intervention, 81.0% (1 415/1 747) smokers started to quit and 36.6% (518/1 415) quit smoking with drugs, both higher than the baseline level (all P values<0.001). By the end of the program, 60.2% (852/1 415) of the medical staff had quit smoking successfully. Conclusion: "Smoking cessation: Doctor first"program can improve the willingness to quit and the proportion of using smoking cessation drugs of medical staff.

Abstract
UNLABELLED This paper systematically reviewed and assessed all retrievable pharmacoeconomic studies on denosumab for the treatment of osteoporosis. Denosumab was more cost-effective in patients with older age, prior fracture experience, lower BMD T-scores, and more risk factors. ESCEO-IOF guidelines were more applicable to improve the quality of pharmacoeconomic studies in osteoporosis. INTRODUCTION There are many pharmacoeconomic studies on denosumab for osteoporosis. However, the corresponding reviews are outdated or incomplete and need to be updated and refined. This article aims to systematically review and evaluate all retrievable pharmacoeconomic studies of denosumab for osteoporosis. METHODS A systematic literature search was performed utilizing PubMed, EMBASE(Ovid), Proquest(EconLit), Chongqing VIP, WanFang Database, and Chinese National Knowledge Infrastructure to identify full-text articles published before September 2021. The quality of full-text articles was evaluated by the Consolidated Health Economic Evaluation Reporting Standards(CHEERS) and the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases International Osteoporosis Foundation guideline(ESCEO-IOF). RESULTS In total, 21 full-text articles were eligible for inclusion. Denosumab for postmenopausal osteoporosis was not dominant compared to zoledronate and teriparatide. However, denosumab was dominant compared with strontium ranelate, raloxifene, and ibandronate in patients over 65 years. The probabilities of denosumab being cost-effective or dominant were more than 85% compared with no treatment and risedronate in patients aged over 70 years. Compared to alendronate, the highest rate of denosumab dominance occurred in patients aged 65 to 75 years, at about 65%. Most of the articles had higher CHEERS scores than ESCEO-IOF scores (converted into percentages). CONCLUSIONS The cost-effectiveness of denosumab for the treatment of osteoporosis was influenced by multiple factors. Generally, denosumab was more cost-effective in patients with older age, prior fracture experience, lower BMD T-scores, and more risk factors. ESCEO-IOF guidelines were more applicable to improve the transparency, generalization, and quality of pharmacoeconomic studies in osteoporosis.

Abstract
Based on the open data of China Health and Nutrition Survey (CHNS), 249 children, adolescents and 249 heads of families who completed two rounds of surveys in 2011 and 2015 were selected in this study. According to the fast food consumption of children and adolescents, they were divided into fast food consumption group and non-fast food consumption group. Logistic regression model was used to analyze the relationship between children and adolescents watching Food TV advertising and fast food consumption. After adjusting relevant factors, the results showed that children and adolescents requiring their parents to buy food in TV advertisements (OR=3.122, P=0.001), parents buying food for their children in TV advertisements (OR=4.717, P=0.036), children and adolescents buying food in TV advertisements themselves (OR=3.728, P=0.041), children and adolescents' preference for food in TV advertisements (OR=2.946, P=0.044) and the frequency of children and adolescents reported by their parents asking their parents to buy food in TV advertisements (OR=3.113, P=0.002) were associated with children and adolescents' fast food consumption.

Abstract
Colorectal cancer is the third most common cancer in the world. The treatments include surgery, chemotherapy, radiotherapy and targeted therapy. The guidelines of many tumor types have been rewritten with the advent of immune checkpoint inhibitors. There are significant differences in the efficacy of immune checkpoint inhibitors in colorectal cancer according to microsatellite status. Microsatellite instability-high (MSI-H) colorectal cancer has made a breakthrough in immunotherapy, whether in the late-line, first-line, adjuvant or neoadjuvant therapy. The success of KEYNOTE-177 study has changed the guidelines with pembrolizumab becoming a standard treatment in the first-line treatment of MSI-H advanced colorectal cancer. The NICHE study, which used immunotherapy as neoadjuvant treatment of colorectal cancer, has made exciting achievements in MSI-H colorectal cancer. For microsatellite stability (MSS) colorectal cancer, many studies are ongoing, and immunotherapy is still unable to challenge the status of traditional treatment. In this paper, we review the clinical trials related to immune checkpoint inhibitors of colorectal cancer, expecting to provide references for the development of colorectal cancer immunotherapy.

Abstract
Immune checkpoint inhibitors have progressed rapidly over the past decade and have become one of the most promising oncology treatments. However, immune checkpoint inhibitors reduce T-cell tolerance and lead to a unique spectrum of immune-related adverse events (IRAE). IRAE can involve multiple systems, including endocrine, gastrointestinal, respiratory and skin systems and there is no predictive marker with high specificity and sensitivity. Mild IRAE can be alleviated by discontinuing immune checkpoint inhibitors while severe IRAEs require active intervention. The first-line treatment is glucocorticoids, and immunosuppressants can be considered in refractory cases. However the optimal choice of immunosuppressants is currently controversial. This review provides an overview of the epidemiology and possible mechanisms of immune-related adverse events, outlines some promising predictive biomarkers, and describes several immunotherapy-related organ toxicity and management.

Abstract
BACKGROUND AND PURPOSE MR imaging provides critical information about fetal brain growth and development. Currently, morphologic analysis primarily relies on manual segmentation, which is time-intensive and has limited repeatability. This work aimed to develop a deep learning-based automatic fetal brain segmentation method that provides improved accuracy and robustness compared with atlas-based methods. MATERIALS AND METHODS A total of 106 fetal MR imaging studies were acquired prospectively from fetuses between 23 and 39 weeks of gestation. We trained a deep learning model on the MR imaging scans of 65 healthy fetuses and compared its performance with a 4D atlas-based segmentation method using the Wilcoxon signed-rank test. The trained model was also evaluated on data from 41 fetuses diagnosed with congenital heart disease. RESULTS The proposed method showed high consistency with the manual segmentation, with an average Dice score of 0.897. It also demonstrated significantly improved performance (P < .001) based on the Dice score and 95% Hausdorff distance in all brain regions compared with the atlas-based method. The performance of the proposed method was consistent across gestational ages. The segmentations of the brains of fetuses with high-risk congenital heart disease were also highly consistent with the manual segmentation, though the Dice score was 7% lower than that of healthy fetuses. CONCLUSIONS The proposed deep learning method provides an efficient and reliable approach for fetal brain segmentation, which outperformed segmentation based on a 4D atlas and has been used in clinical and research settings.

Abstract
As food preferences and eating habits form early in life, the development of healthy eating habits in early childhood is a way to prevent diet-related diseases. The dietary pattern approach examines the effect of an overall diet on health outcomes, instead of individual foods or nutrients, thereby presenting a comprehensive evaluation of children's dietary intake. This article reviews the current literature to summarize the main methods for assessing dietary patterns and explore relationships between children's dietary patterns and obesity, puberty onset, cardiovascular diseases, and neurodevelopment. The purpose of this review is to provide evidence-based support for reducing the risk of diet-related diseases in children and recommendations for future research directions.

Abstract
Recently, the LHAASO Collaboration published the detection of 12 ultrahigh-energy γ-ray sources above 100 TeV, with the highest energy photon reaching 1.4 PeV. The first detection of PeV γ rays from astrophysical sources may provide a very sensitive probe of the effect of the Lorentz invariance violation (LIV), which results in decay of high-energy γ rays in the superluminal scenario and hence a sharp cutoff of the energy spectrum. Two highest energy sources are studied in this work. No signature of the existence of the LIV is found in their energy spectra, and the lower limits on the LIV energy scale are derived. Our results show that the first-order LIV energy scale should be higher than about 10^{5} times the Planck scale M_{Pl} and that the second-order LIV scale is >10^{-3}M_{Pl}. Both limits improve by at least one order of magnitude the previous results.

Abstract
Objective: To investigate the efficacy and safety of infliximab (IFX) therapy for children with Kawasaki disease. Methods: Sixty-eight children with Kawasaki disease who received IFX therapy in Children's Hospital of Fudan University from January 2014 to April 2021 were enrolled. The indications for IFX administration, changes in laboratory parameters before and after IFX administration, response rate, drug adverse events and complications and outcomes of coronary artery aneurysms (CAA) were retrospectively analyzed. Comparisons between groups were performed with unpaired Student t test or Mann-Whitney U test or chi-square test. Results: Among 68 children with Kawasaki disease, 52 (76%) were males and 16 (24%) were females. The age of onset was 2.1 (0.5, 3.8) years. IFX was administered to: (1) 35 children (51%) with persistent fever who did not respond to intravenous immunoglobulin (IVIG) or steroids, 28 of the 35 children (80%) developed CAA before IFX therapy; (2) 32 children (47%) with continuous progression of CAA; (3) 1 child with persistent arthritis. In all cases, IFX was administered as an additional treatment (the time from the onset of illness to IFX therapy was 21 (15, 30) days) which consisted of second line therapy in 20 (29%), third line therapy in 20 (29%), and fourth (or more) line therapy in 28 (41%). C-reactive protein (8 (4, 15) vs. 16 (8, 43) mg/L, Z=-3.38, P=0.001), serum amyloid protein A (17 (10, 42) vs. 88 (11, 327) mg/L, Z=-2.36, P=0.018) and the percentage of neutrophils (0.39±0.20 vs. 0.49±0.21, t=2.63, P=0.010) decreased significantly after IFX administration. Fourteen children (21%) did not respond to IFX and received additional therapies mainly including steroids and cyclophosphamide. There was no significant difference in gender, age at IFX administration, time from the onset of illness to IFX administration, the maximum coronary Z value before IFX administration, and the incidence of systemic aneurysms between IFX-sensitive group and IFX-resistant group (all P>0.05). Infections occurred in 11 cases (16%) after IFX administration, including respiratory tract, digestive tract, urinary tract, skin and oral infections. One case had Calmette-Guérin bacillus-related adverse reactions 2 months after IFX administration. All of these adverse events were cured successfully. One child died of CAA rupture, 6 children were lost to follow up, the remaining 61 children were followed up for 6 (4, 15) months. No CAA occurred in 7 children before and after IFX treatment, while CAA occurred in 54 children before IFX treatment. CAA regressed in 23 (43%) children at the last follow-up, and the diameter of coronary artery recovered to normal in 10 children. Conclusion: IFX is an effective and safe therapeutic choice for children with Kawasaki disease who are refractory to IVIG or steroids therapy or with continuous progression of CAA.

Abstract
BACKGROUND AND PURPOSE Papillary thyroid carcinoma (PTC) is an endocrine malignancy. Increasing evidence highlights microRNAs (miRNAs) as important participants in PTC. Here, we investigated the role of miR-181a in PTC. METHODS A microarray-based analysis was performed to identify the differential expression of miR-181a in PTC, which was validated with RT-qPCR. Protein expression of the proliferation-related factor Ki-67 and apoptosis- and migration-related factors in PTC was assessed with immunoblot analysis. A dual-luciferase reporter gene assay was adopted to verify the relationship between miR-181a and lysine demethylase 5C (KDM5C). Chromatin immunoprecipitation (ChIP) was used to detect the level of the H3K4me3 modification on S100 calcium-binding protein A2 (S100A2). Cell viability, apoptosis, and invasion and migration abilities were evaluated by Cell Counting Kit-8 (CCK-8), flow cytometry, and transwell assays, respectively. The in vitro results were verified in in vivo nude mouse models. RESULTS miR-181a was highly expressed in PTC tissues and cell lines. Silencing miR-181a repressed the proliferation and migration of PTC cells. KDM5C was identified as the target gene of miR-181a and represses S100A2 expression through histone demethylation to diminish the migration and proliferation of PTC cells. miR-181a depletion suppressed tumor growth. CONCLUSION Collectively, these results suggest that highly expressed miR-181a promotes the proliferation of PTC cells by increasing the expression of the oncogene S100A2. This study contributes to the advancement of miR-181a-targeted therapeutics.

Abstract
OBJECTIVES This study aimed to assess whether raised baseline plasma tHcy concentrations increased the risks of major adverse cardiovascular events (MACE) and all-cause death outcomes in older patients with obstructive sleep apnea (OSA). DESIGN A multicenter, prospective, observational study. SETTING Beijing, Shandong Province, Gansu Province of China. PARTICIPANTS A total of 1, 290 OSA patients aged 60 to 96 years from sleep centers of six hospitals in China consecutively recruited between January 2015 and October 2017. MEASUREMENTS Cox proportional models assessed the association between tHcy and the risk of new-onset all events among Chinese older OSA patients. RESULTS The final analysis (60.1% male; median age, 66 years) used data from 1, 100 subjects during a median follow-up of 42 months, a total of 105 (9.5%) patients developed MACE and 42 (3.8%) patients died. Multivariable Cox regression analysis showed higher adjusted hazard ratios (aHRs) of MACE, myocardial infarction (MI), hospitalization for unstable angina, and composite of all events with tHcy levels in the 4th quartile (HR=5.93, 95% CI: 2.79-12.59; HR=4.72, 95% CI:1.36-4.61; HR=4.26, 95% CI:1.62-5.71; HR=4.17, 95% CI:2.23-7.81) and the 3rd quartile (HR=3.79, 95% CI:1.76-8.20; HR=3.65, 95% CI:1.04-2.98; HR=2.75, 95% CI:1.08-3.76; HR=2.51, 95% CI:1.31-4.83) compared to reference tHcy levels in quartile 1, respectively, while the aHRs (95% CIs) of all-cause death showed significantly higher only in the highest tHcy level quartile than in the lowest quartile (HR=3.20, 95% CI=1.16-8.84, P=0.025) with no significant differences in risks of cardiovascular death and hospitalisation for heart failure among groups (P>0.05). CONCLUSIONS tHcy, a marker of prognosis for older OSA patients, was significantly associated with the increased risk of MACE and all-cause death in this population independent of BMI, smoking status, and other potential risk factors, but not all clinical components events of MACE. New therapeutic approaches for older patients with OSA should mitigate tHcy-associated risks of MACE, and even all-cause death.

Abstract
Objective: To analysis the anatomical features of normal vestibular nerve canal based on 10 μm otology CT. Methods: Sixty-seven patients (103 ears) underwent 10 μm otology CT examinations in Department of Radiology, Beijing Friendship Hospital, Capital Medical University from September 2020 to March 2021 were retrospectively recruited. There were 24 males and 43 females, aged from 18 to 70 (40±17) years. According to the morphology of the inferior vestibular nerve canal, it can be divided into four types as follows: uniform straight type, curved type, ampullary type and direct connection. The anatomical variables of the superior vestibular nerve canal (external orifice, isthmus and internal orifice widths, canal length, angle with labyrinthine segment of the facial nerve) and inferior vestibular nerve canal (widths of the externaland internal orifice, canal length, angles with long axis of the vestibule and the modiolus) between the different sides, genders and canal morphologies were analyzed and compared, respectively. Results: 100% superior vestibular nerve canals and 75.7% (78/103) inferior vestibular nerve canals are clearly depicted by otology CT. The left-side ear presented with larger internal orifice diameter of the superior vestibular neve canal [(1.46±0.47) mm vs (1.31±0.41) mm], and a smaller angle between the inferior vestibular neve canal and the modiolus [(41.6±16.9)° vs (51.6±21.0)°] than the right-side ear (all P<0.05, respectively), respectively. Compared to females, males demonstrated larger internal orifice of the superior vestibular nerve canal [(1.55±0.37) mm vs (1.28±0.36) mm, P<0.05]. The uniform straight type of the inferior vestibular nerve canal was the most common type (62.1%, 64/103), followed by the direct connection (19.4%, 20/103), and the ampullary type was the least common type (4.9%, 5/103). There were significant differences in external diameter and angles with the long axis of the vestibule and the modiolus between the four morphologies of the superior vestibular nerve canal (all P<0.05, respectively). Conclusion: Ten μm otology CT is capable of depicting normal vestibular nerve canal clearly. Quantitative measurement of the normal vestibular nerve canal can provide references for the imaging diagnosis and preoperative evaluation of lesions in this area.

Abstract
Objective: To explore the performance of a deep learning algorithm that combined multi-view fusion with active contour constrained for ossicles segmentation on the 10 μm otology CT images. Methods: The 10 μm otology CT image data from 79 cases (56 cases were from volunteers and 23 cases were from specimens) were retrospectively collected in the Radiology Department of Beijing Friendship Hospital from October 2019 to December 2020. An annotation of malleus, incus, and stapes were conducted. Then the datasets were established and were divided into training set (n=55), validation set (n=8), and test set (n=16). Using the rapid localization of the region of interest combined with the precise segmentation algorithm, the malleus, incus and stapes were segmented and fused from three perspectives of coronal, sagittal and cross-sectional views. Besides, an active contour loss was designed simultaneously for the segmentation of stapes. Dice similarity coefficient (DSC) was used as the objective evaluation metric for the evaluation of the segmentation results. The inter group DSC of the proposed method was compared with that of the basic method and other methods. Results: The average DSC values of the multi-view fusion segmentation algorithm for malleus, incus and stapes reached up to 94.2%±2.7%, 94.6%±2.6% and 76.0%±5.5%, respectively. After adopting the constraint of active contour loss method, the average DSC of stapes was improved (76.4%±5.4% vs 76.0%±5.5%). The visualization results also demonstrated that the segmentation results of the stapes were more complete. Conclusions: Multi-view fusion algorithm based on 10 μm otology CT images can realize accurate segmentation of malleus and incus. Combined with the constraint of active contour loss method, the segmentation accuracy of stapes can be further improved.

Abstract
Objective: To evaluate the morphology of isthmus of the vestibular aqueduct (VA) and its relationship with the occurrence, course of Meniere's disease (MD) and the degree of hearing loss based on 10 μm otology CT. Methods: A total of 13 patients with MD in Beijing Friendship Hospital, Capital Medical University from October 2020 to July 2021, including 4 males and 9 females, age from 16 to 77 (56±16) years, were prospectively enrolled. All patients underwent 10 μm otology CT examination. The included lesion side was the MD affected group (14 sides), and the non-lesion side was the MD healthy group (12 sides). According to the 1∶2 side, 16 sex-and side matched cases (28 sides) without external and middle ear disease were included in the control group, including 4 males and 12 females, age from 16 to 77 (56±14) years. The horizontal semicircular canal showed on the largest plane was considered as the standard cross-section, and continuous observation was made on this image. According to the display type of isthmus of the VA, it was divided into Ⅰ to Ⅳ grades. Kruskal Wallis test was used to compare the morphological differences of VA isthmus among the affected group, the healthy group and the control group. The degree of hearing impairment was assessed by pure tone audiometry (PTA) results, which were divided into normal/mild/moderate/moderately severe/severe/extremely severe hearing impairment. Spearman correlation analysis was used to compare the correlation between the morphological rating of VA isthmus on the affected side and age, course of disease and the results of pure tone audiometry (PTA). Results: The proportions of VA isthmic morphology GRADE Ⅰ,Ⅱ,Ⅲ,Ⅳ in the MD affected group were 28.6% (4/14), 42.9% (6/14), 21.4% (3/14), 7.1% (1/14), those in the MD healthy group were 0 (0/12), 33.3% (4/12), 33.3% (4/12), 33.3% (4/12), and those in the control group were 0 (0/28), 7.1% (2/28), 64.2% (18/28), 28.6% (8/28). The VA isthmus scores [M (Q1, Q3)] of MD affected group was lower than that of MD healthy group [2 (1, 3) vs 3 (2, 4)] and control group [2 (1, 3) vs 3 (3, 4)] (all P<0.05, respectively). The morphology of the VA isthmus on the affected side of MD was negatively correlated with age (r=-0.81, P=0.002), and there was no correlation with the course of disease and degree of hearing impairment (r=-0.40, r=-0.26; all P>0.05, respectively). Conclusion: The stenosis of the VA isthmus in MD was a possible anatomical factor for the occurrence of MD.

Abstract
Objective: To explore the influencing factors of abnormal menstruation of female workers in a petrochemical enterprise. Methods: A total of 5186 female employees in a petrochemical enterprise were selected as the research objects from July 2018 to December 2019. A questionnaire survey was conducted from four aspects: basic information, occupational status, psychological status at work, reproductive and reproductive health, and a multivariate logistic regression model was used for analysis. Results: Among 5132 female workers, 676 were postmenopausal and 1117 (25.1%) among 4456 non-postmenopausal women had abnormal menstruation in the last 6 months. Logistic regression analysis showed that age (<30、30~35 years) and length of service (≤20 years) were protective factors (OR=0.573, 0.590, 0.798, P<0.05) . Age (40~45、45~50 years old) , sleep duration (<6 h) , premature OR late menopause of maternal relatives, occupational exposure to dust, occupational exposure to chemicals, not wearing earplugs, leave due to health reasons in the last 6 months, reproductive tract infection OR symptoms in the last 6 months, spontaneous abortion, induced abortion, physical fatigue and mental fatigue were risk factors for menstrual abnormalities in female workers (OR=2.318, 5.544, 1.231, 1.199, 1.336, 1.403, 1.351, 1.538, 1.613, 1.584, 1.199, 1.601, 1.936, P<0.05) . Conclusion: The abnormal menstruation of female workers is affected by many factors in the occupational process, and specific measures should be taken to improve the reproductive health of female workers.
