Abstract
Twenty-five patients diagnosed with otogenic vertigo at the outpatient clinic of the Department of Otolaryngology-Head and Neck Surgery, Shanghai Jiao Tong University Affiliated Sixth People's Hospital from January to June 2020 were selected. Among them, 8 cases were male and 17 cases were female, aged (48±13) years. All the patients underwent internet combined with offline follow-up vestibular rehabilitation for 12 weeks, which included vestibulo-ocular reflex exercises, proprioceptive exercises and static/dynamic balance exercises. Computerized dynamic posturography (CDP) and dizziness handicap inventory (DHI) scores were compared before and after rehabilitation. The DHI score improved significantly after 12 weeks of vestibular rehabilitation (48.3±15.9 vs 26.7±17.9, t=5.319, P<0.001). Meanwhile, the sensory organization test (SOT) score was also improved (73.3±8.1 vs 76.1±6.6, t=2.066, P=0.050), while the difference of motor control test (MCT) latent stage score before and after rehabilitation was not statistically significant (140±13 vs 141±16, t=0.791, P=0.436). The current study demonstrates that vestibular rehabilitation based on mobile internet is convenient, economical and effective, and patients can benefit from it.

Abstract
OBJECTIVE This study investigated the effect of melatonin administration in combination with the CoSynch-56 protocol on the conception rate after artificial insemination (AI) in beef heifers. METHODS Eighty-six beef heifers were allocated to four treatments in combination with CoSynch-56 treatment. All heifers, excluding the control group (CTR = 25), were injected with melatonin on day 1. The melatonin (MT = 20) and MT + human chorionic gonadotropin (MT + hCG = 21) groups received no further treatment with melatonin. Each heifer was treated with gonadotropin-releasing hormone (GnRH) on day 4, prostaglandin F2α (PGF2α) on day 11, and GnRH and AI 56 h later. The fourth group (2MT = 20) was injected again with melatonin concurrent with AI, and the MT + hCG group received hCG on day 19. Pregnancy diagnosis was performed using transrectal ultrasonography 45 days after AI and blood samples were collected via caudal venipuncture on days 0-1, 14-15, 24 and 59. Concentrations of progesterone (P4) and the activities of oxidative stress-related enzymes were determined using enzyme-linked immunosorbent assay. RESULTS The conception rate was greater in the 2MT group (75%) than in the other groups, while there was no significant difference among the CTR (44%), MT (45%) and MT + hCG (38.1%) groups. Treatment with melatonin increased superoxide dismutase and glutathione peroxidase activities and decreased malondialdehyde concentrations but did not significantly affect the concentration of P4. CONCLUSION Our results indicate that the administration of melatonin twice during the CoSynch-56 protocol may increase conception rates in beef heifers.

Abstract
OBJECTIVE In recent years, coronary heart disease (CHD) has become a disease that cannot be ignored by residents of our country, because CHD will not only endanger people's quality of life, but also threaten their lives. Therefore, this research mainly explores the correlation between myocardial infarction (MI) with endoplasmic reticulum (ER) stress and apoptosis. MATERIALS AND METHODS First, we constructed a model of myocardial ischemia and hypoxia (I/H) in vivo and in vitro, and examined the change of CACNA1H expression. At the same time, in order to research the role of CACNA1H, we chose CACNA1H-specific inhibitor ABT-639 to next research and detect changes in heart injury by detecting changes in creatine kinase (CK) content and lactate dehydrogenase (LDH) activity. Next, we used TUNEL staining and immunofluorescence staining to detect changes in apoptosis and ER stress, and analyzed changes in ER stress and apoptotic pathway expression by Western blotting and quantitative Real-Time Polymerase Chain Reaction (qRT-PCR). RESULTS At 28 days after MI, the cardiac function of the mice was significantly reduced, the myocardial cell apoptosis rate was dramatically increased, and CACNA1H expression was dramatically increased in vivo and in vitro. In addition, we treated the model group with the ABT-639, and found that ABT-639 can partially protect myocardial function and relieve myocardial cell apoptosis. At the same time, ABT-639 may reduce H9c2 injury after I/H by reducing the degree of ER stress, because we found that the use of ABT-639 can dramatically reduce ER stress-related factors expression, and can inhibit the expression of apoptosis-related factors Caspase-3 and Caspase-9. CONCLUSIONS The CACNA1H inhibitor ABT-639 can alleviate myocardial cell apoptosis caused by MI by reducing the ER stress response.

Abstract
Cavitation bubbles can be seeded from a plasma following optical breakdown, by focusing an intense laser in water. The fast dynamics are associated with extreme states of gas and liquid, especially in the nascent state. This offers a unique setting to probe water and water vapor far-from equilibrium. However, current optical techniques cannot quantify these early states due to contrast and resolution limitations. X-ray holography with single X-ray free-electron laser pulses has now enabled a quasi-instantaneous high resolution structural probe with contrast proportional to the electron density of the object. In this work, we demonstrate cone-beam holographic flash imaging of laser-induced cavitation bubbles in water with nanofocused X-ray free-electron laser pulses. We quantify the spatial and temporal pressure distribution of the shockwave surrounding the expanding cavitation bubble at time delays shortly after seeding and compare the results to numerical simulations.

Abstract
Background:Risankizumab (RZB) is a humanized immunoglobulin G1 monoclonal antibody that specifically inhibits interleukin 23 by binding to its p19 subunit. RZB is being investigated as a treatment for adults with psoriatic arthritis (PsA).Objectives:To compare the efficacy and safety of RZB vs placebo (PBO) for the treatment of active PsA in patients who have had inadequate response or intolerance to ≥ 1 conventional synthetic disease modifying antirheumatic drug (csDMARD-IR).Methods:In KEEPsAKE 1 (NCT03675308), eligible adults (csDMARD-IR with ≥ 5 swollen joints [SJC] and ≥ 5 tender joints [TJC]) were randomized (1:1) to receive blinded subcutaneous RZB 150 mg or PBO at weeks 0, 4, and 16. The primary endpoint was the proportion of patients achieving 20% improvement in American College of Rheumatology score (ACR20) at week 24. Ranked secondary and other secondary endpoints are shown in the Table 1. Safety was assessed throughout the study. Results reported here are from the 24-week double-blind period; the open-label period with all patients receiving RZB is ongoing.Results:964 patients (RZB, N = 483; PBO, N = 481) were evaluated at week 24. Demographics and baseline characteristics were generally balanced between treatment groups (mean duration of PsA: 7.12 years; mean SJC: 12.2; mean TJC: 20.6; mean body surface area involved with psoriasis [BSA] in patients with BSA ≥ 3%: 16.7%). A significantly greater proportion of RZB- vs PBO-treated patients (57.3% and 33.5%, respectively) achieved the primary endpoint of ACR20 at week 24 (P < .001; Table 1). Significant differences were also observed for RZB vs PBO for the first 8 ranked secondary endpoints (P < .001 for all; Table 1). Serious adverse events were reported for 2.5% and 3.7% of RZB- and PBO-treated patients, respectively; serious infections were reported for 1.0% and 1.2%. There was 1 death in the RZB group.Conclusion:RZB resulted in significantly greater improvements in signs and symptoms of PsA compared with PBO and was well tolerated in patients who were csDMARD-IR.Disclosure of Interests:Lars Erik Kristensen Speakers bureau: LK has received honoraria or fees for serving as a speaker or consultant from AbbVie, Amgen, Biogen, Bristol-Myers Squibb, Gilead, Janssen, Lilly, Merck, Novartis, Pfizer, and UCB., Consultant of: LK has received honoraria or fees for serving as a speaker or consultant from AbbVie, Amgen, Biogen, Bristol-Myers Squibb, Gilead, Janssen, Lilly, Merck, Novartis, Pfizer, and UCB., MAURO KEISERMAN Speakers bureau: MK has received honoraria or fees for serving on advisory boards, as a speaker or as a consultant, and grants as a principal investigator from AbbVie, Amgen, Bristol-Myers Squibb, Celgene, GlaxoSmithKline, Janssen, Novartis, Pfizer, Roche, and UCB., Consultant of: MK has received honoraria or fees for serving on advisory boards, as a speaker or as a consultant, and grants as a principal investigator from AbbVie, Amgen, Bristol-Myers Squibb, Celgene, GlaxoSmithKline, Janssen, Novartis, Pfizer, Roche, and UCB., Grant/research support from: MK has received honoraria or fees for serving on advisory boards, as a speaker or as a consultant, and grants as a principal investigator from AbbVie, Amgen, Bristol-Myers Squibb, Celgene, GlaxoSmithKline, Janssen, Novartis, Pfizer, Roche, and UCB., Kim Papp Speakers bureau: KP has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant, as well as grants as principal investigator from AbbVie, Amgen, Astellas, Bausch Health (Valeant), Baxalta, Baxter, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Coherus, Dermira, EMD Serono, Forward Pharma, Galderma, Genentech, GlaxoSmithKline, Janssen, Kyowa Kirin, LEO Pharma, Lilly, MedImmune, Merck, Novartis, Pfizer, Regeneron, Roche, Sanofi Genzyme, Stiefel, Sun Pharma, Takeda, and UCB., Consultant of: KP has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant, as well as grants as principal investigator from AbbVie, Amgen, Astellas, Bausch Health (Valeant), Baxalta, Baxter, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Coherus, Dermira, EMD Serono, Forward Pharma, Galderma, Genentech, GlaxoSmithKline, Janssen, Kyowa Kirin, LEO Pharma, Lilly, MedImmune, Merck, Novartis, Pfizer, Regeneron, Roche, Sanofi Genzyme, Stiefel, Sun Pharma, Takeda, and UCB., Grant/research support from: KP has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant, as well as grants as principal investigator from AbbVie, Amgen, Astellas, Bausch Health (Valeant), Baxalta, Baxter, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Coherus, Dermira, EMD Serono, Forward Pharma, Galderma, Genentech, GlaxoSmithKline, Janssen, Kyowa Kirin, LEO Pharma, Lilly, MedImmune, Merck, Novartis, Pfizer, Regeneron, Roche, Sanofi Genzyme, Stiefel, Sun Pharma, Takeda, and UCB., Leslie McCasland Speakers bureau: LM has received fees for serving on an advisory board from Lilly., Douglas White Speakers bureau: DW has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant from AbbVie, Merck, Novartis, and Roche., Consultant of: DW has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant from AbbVie, Merck, Novartis, and Roche., Lisa Barcomb Shareholder of: LB is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Employee of: LB is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Wenjing Lu Shareholder of: WL is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Employee of: WL is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Zailong Wang Shareholder of: ZE is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Employee of: ZE is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Ahmed M.

Abstract
With the rapid development of industrialization and urbanization in China, energy and vehicle consumption have continued to increase in recent years and air pollution has become serious. In early 2020, Corona Virus Disease 2019 broke out in Wuhan, China. From January 29, 2020, several sources of the air pollution almost all stopped working, including gasoline burning vehicles, dust producing building sites, coal-fired factories, etc. Five indicators of the atmospheric environmental quality were observed from December 19, 2019 to April 30, 2020 in nine cities and 1-h average concentrations, 24-h average concentrations and Air Quality Index were assessed. The 1-h average concentrations of the nitrogen dioxide, the ozone and the sulfur dioxide showed obvious difference though the closure did not change the sequence of the five pollutants' concentrations in the air at diverse sampling moments. The changing of the 24-h average concentrations of the five pollutants indicated the amount of pollutants in the air were greatly affected by human activities. The nitrogen dioxide, the sulfur dioxide and the particulate matters decreased obviously in the closure. The air in the metropolis and the south-east cities were relatively clean and the pollutants' concentrations decreased slightly during the closure period. The northern and the heavy industrial cities showed significant drop on air pollution indicators and the air quality of the two city groups could be greatly improved if some effective measures could be taken of environmental management and regional development.

Abstract
A high-temperature oven based on the inductive heating technology was developed successfully at the Institute of Modern Physics in 2019. This oven features a durable operation temperature of over 2000 °C inside the tantalum susceptor. By carefully designing the oven structure, the material compatibility issue at high temperature has been successfully solved, which enables the production and routine operation of refractory metal ions with SECRAL-II (Superconducting Electron Cyclotron Resonance ion source with Advanced design in Lanzhou No. 2). To further apply this type of oven to the room temperature ECR ion sources LECR4 and LECR5 (Lanzhou Electron Cyclotron Resonance ion source No. 4 and 5), a mini-inductive heating oven has been fabricated and tested in 2020. By directly evaporating calcium oxide, some high charge state calcium beams have been produced successfully, such as 52 euA of 40Ca16+, 30 euA of 40Ca17+, and 12 euA of 40Ca18+. The detailed design and testing results will be presented and discussed.

Abstract
OBJECTIVE The aim of this study was to explore the association between the expression of adenosine monophosphate-activated protein kinase (AMPK) pathway and adiponectin (APN), leptin, and vascular endothelial function in rats with coronary heart disease (CHD). MATERIALS AND METHODS Experimental rats were divided into three groups, including: control (Col) group, CHD model (CHD) group, and CHD+AMPK activator (CHD+AICAR) group. Except those in Col group, all rats were fed with high-fat diet and intraperitoneally injected with pituitrin to establish the CHD model. The levels of serum APN, leptin, and endothelin-1 (ET-1) were determined via enzyme-linked immunosorbent assay (ELISA). The content of serum nitric oxide (NO) was detected using the nitrate reductase method. Meanwhile, the expression of AMPK pathway-related protein AMPKα in vascular endothelial tissues was detected via Western blotting (WB). Aortic vascular endothelial cells (VECs) were cultured with AICAR or ET-1 in vitro. Subsequently, the expressions of AMPK pathway and protein kinase B (AKT) pathway-related proteins were determined through co-immunoprecipitation and WB. Moreover, the expression level of NO in VECs was determined using the DAF-FM DA fluorescence probe. RESULTS Compared with Col group, CHD group showed significantly decreased levels of serum APN and NO (p<0.05), significantly increased the levels of leptin and ET-1 (p<0.05), as well as remarkably decreased protein expression of p-AMPKα in vascular endothelial tissues (p<0.05). After injection of AMPK activator AICAR (200 mg/kg), the protein expression of p-AMPKα in CHD rats was significantly activated (p<0.05). The levels of serum APN and NO were remarkably upregulated (p<0.05), while the levels of leptin and ET-1 were significantly reduced (p<0.05). Besides, AICAR could evidently activate the activity of AMPK pathway in VECs in vitro, upregulate the protein levels of p-eNOS (Ser1177) and p-AMPKα, and promote the secretion of NO (p<0.05). In addition, AICAR remarkably inhibited ET-1-induced expression of AKT pathway (p<0.05). CONCLUSIONS Activating the AMPK pathway may play a positive role in the normal function of VECs and exert a certain curative effect on CHD in rats.

Abstract
We present results from the SPring-8 Angstrom Compact free electron LAser facility, where we used a high intensity (∼10^{20} W/cm^{2}) x-ray pump x-ray probe scheme to observe changes in the ionic structure of silicon induced by x-ray heating of the electrons. By avoiding Laue spots in the scattering signal from a single crystalline sample, we observe a rapid rise in diffuse scattering and a transition to a disordered, liquidlike state with a structure significantly different from liquid silicon. The disordering occurs within 100 fs of irradiation, a timescale that agrees well with first principles simulations, and is faster than that predicted by purely inertial behavior, suggesting that both the phase change and disordered state reached are dominated by Coulomb forces. This method is capable of observing liquid scattering without masking signal from the ambient solid, allowing the liquid structure to be measured throughout and beyond the phase change.

Methods: From January 2018 to June 2019, 175 healthy volunteers (21-65 years, 58 males and 117 females) with normal glucose tolerance (NGT) and 80 diabetic patients (18-70 years, 44 males and 36 females) were enrolled in Shanghai Jiao Tong University Affiliated Sixth People's Hospital. Saliva was collected by saliva collection tube, and 1,5-AG was measured using both enzymatic and mass spectrometry methods. Serum 1,5-AG was determined by enzymatic method. Results: In NGT subjects, both serum and saliva 1,5-AG levels detected by enzymatic method were positively correlated with the saliva 1,5-AG levels detected by liquid chromatography-mass spectrometry (r=0.247 and 0.523, respectively, both P<0.05). However, there was no significant correlation between saliva and serum 1,5-AG levels detected by enzymatic method (r=-0.074, P=0.333). In diabetic patients, both serum and saliva 1,5-AG levels detected by enzymatic method were positively correlated with the saliva 1,5-AG levels detected by gas chromatography-mass spectrometry (r=0.284 and 0.423, respectively, both P<0.05). However, there was no significant correlation between saliva and serum 1,5-AG levels detected by enzymatic method (r=-0.079, P=0.487). Conclusions: Both serum and saliva 1,5-AG levels detected by enzymatic method have a good consistency with saliva 1,5-AG levels detected by mass spectrometry method. The saliva and serum 1,5-AG levels detected by enzymatic method are not well correlated, and thus the enzymatic detection of saliva 1,5-AG needs further improvement in clinical practice.

Abstract
Abstract
Introduction/Objective
Transfusion of blood components is one of the most common medical procedures with transfusion reactions being the greatest associated risk. Acute pain transfusion reaction (APTR) is one such under- recognized and under-reported risk, likely due to scarcity of literature and lack of criteria for diagnosis.
Methods
A literature review was performed using PubMed to search for the keywords: “acute pain transfusion reaction”. This searched revealed two articles, from which one abstract and a book chapter were also identified.
Results
A 58-year-old female with chronic myeloid leukemia and pre-existing pain received 44 leukoreduced irradiated blood components [7 pooled platelets, 17 apheresis platelets, 20 red blood cells (RBCs)] over two months. Four platelet (one pooled, three apheresis) transfusions resulted in chest and lower back pain starting an average of 15 minutes after initiation of transfusion and resolving following cessation of transfusion. Laboratory evaluations were negative for hemolysis. Despite the patient’s history of pain, these reactions were most consistent with APTRs.
APTRs are rare, most often associated with leukoreduced RBCs and characterized by severe pain in the abdomen, back, flank, or proximal extremities typically occurring within 30 minutes of starting transfusion and abating within 30 minutes following cessation of transfusion. All of our patient’s reported reactions occurred in association with leukoreduced platelets. These reactions may be associated with the leukoreduction, but reports of APTR appeared when leukoreduction became standard practice. Therefore, the etiology remains unknown.
Conclusion
This case aids in the argument that APTR is a complication of transfusion, despite the absence of a clear etiology or diagnostic criteria. Additional research and improved surveillance are necessary to elucidate potential etiology and improve patient care by identifying prevention and treatment options. A diagnostic criterion would aid efforts to harmonize reporting in the United States and collect the hemovigilance data required to improve transfusion outcomes.

Abstract
Objective: To investigate the appropriate cut-off point of time in range (TIR) for evaluating glucose control in type 2 diabetes mellitus (T2DM) patients, and analyze the prevalence of abnormal carotid intima-media thickness (CIMT) and diabetic retinopathy (DR) in different TIR categories. Methods: A total of 2 161 subjects with T2DM (1 183 males) were enrolled from hospitalized patients at the Department of Endocrinology and Metabolism of the Sixth People's Hospital Affiliated to Shanghai Jiao Tong University from January 2005 to February 2012. The age of the enrolled participants was (60.4±11.9) years. Each patient underwent continuous glucose monitoring (CGM) for three consecutive days, then TIR (3.9-10.0 mmol/L), time above range (TAR) and time below range (TBR) were calculated. Fundus photography and carotid artery Doppler ultrasound were performed to diagnose DR and abnormal CIMT (defined as CIMT≥1.0 mm), respectively. Multivariate logistic regression models were used to examine the independent association of different TIR groups with CIMT and DR. Results: All subjects were divided into 4 groups according to TIR:≤40%, 41%-70%, 71%-85% and>85%. Significant linear trends in age, diabetes duration, body mass index (BMI), total cholesterol, glycated hemoglobin A1c (HbA1c), TAR and mean glucose (MG) existed among the 4 groups (all P(trend)<0.05). However, there was only a weak correlation between TIR and TBR (<3.9 mmol/L) (r=0.087, P<0.001), and no significant association was observed between TBR (<3 mmol/L) and the TIR categories (P(trend)=0.378). The overall prevalence of abnormal CIMT and DR was 12.1% and 23.8%, respectively. The prevalence of abnormal CIMT in the 4 groups with ascending levels of TIR was 16.9% (59/349), 12.9% (96/746), 11.2% (57/510) and 9.0% (50/556) (P(trend)<0.001), respectively. And the prevalence of DR was 30.7% (107/349), 29.4% (219/746), 20.8% (106/510) and 14.9% (83/556), respectively (P(trend)<0.001). In the binary logistic regression model by adjusting confounding factors, compared with TIR≤ 40%, the risk of abnormal CIMT was reduced by 33.8% (OR=0.662, 95%CI: 0.456-0.963, P=0.031), 40.8% (OR=0.592, 95%CI: 0.390-0.899, P=0.014), and 45.0% (OR=0.550, 95%CI: 0.358-0.846, P=0.006) in the other three groups, respectively. And the risk of DR was reduced by 2.9% (OR=0.971, 95%CI: 0.725-1.301, P=0.844), 33.4%(OR=0.666, 95%CI: 0.479-0.924, P=0.015) and 53.3% (OR=0.467, 95%CI: 0.331-0.657, P<0.001), respectively. Conclusion: Using 40%, 70% and 85% as cut-off point of TIR helps stratify the risk of diabetic complications, and assess the glucose control (Poor: TIR≤40%; Unsatisfactory: TIR≤70%; Satisfactory: TIR>70%; Optimal: TIR>85%) in patients with T2DM.

Abstract
OBJECTIVE Bladder cancer is considered as the fifth most common cancer in the whole world. This study aimed to investigate the anti-tumor effects of Nanoscale bubbles delivered yeast cytosine deaminase thymidine kinase/connexin 26 (YCD-TK/Cx26) on tumor cell proliferation and tumor growth. MATERIALS AND METHODS Nanoscale bubble was prepared using thin-film hydration-sonication method. Nanoscale bubble-LV5-YCD-TK+PCD-Cx26 was generated and transfected into BIU-87 cells. MTT assay was employed to detect cell viability. Apoptosis was determined using a flow cytometry assay. YCD-TK and Cx26 expressions were detected using Western blot and Real Time-PCR (RT-PCR). BIU-87 cells were transplanted into mice to establish Xenograft models. The tumor volume was recorded. HE staining was used to examine necrosis areas in tumor tissues. RESULTS Nanoscale bubble (Nanoscale bubble-LV5-YCD-TK+PCD-Cx26) successfully mediated YCD-TK and Cx26 gene expression in BIU-87 cells. Nanoscale bubble delivered YCD-TK/Cx26 expression significantly inhibited cell viability and induced apoptosis compared to Nanoscale bubble-LV5-YCD-TK and Nanoscale bubble group (p<0.05). Nanoscale bubble delivered YCD-TK/Cx26 expression triggered significantly higher levels of bystander effect compared to single YCD-TK or single Cx26 gene (p<0.05). Nanoscale bubble delivered YCD-TK/Cx26 expression significantly reduced tumor volume in mouse Xenograft bladder cancer model compared to LV5-YCD-TK and 5-FC+GCV group (p<0.05). Nanoscale bubble delivered YCD-TK/Cx26 expression significantly reduced the necrosis of tumor tissues in mouse Xenograft bladder cancer model compared to LV5-YCD-TK group and 5-FC+GCV group (p<0.05). CONCLUSIONS Nanoscale bubble delivered YCD-TK/Cx26 gene therapeutic system efficiently reduced BIU-87 cell proliferation in vitro, and suppressed tumor growth by inducing necrosis of tumor tissues in mouse Xenograft bladder cancer models.

Abstract
By engineering an anti-parity-time (anti-PT) symmetric cavity magnonics system with precise eigenspace controllability, we observe two different singularities in the same system. One type of singularity, the exceptional point (EP), is produced by tuning the magnon damping. Between two EPs, the maximal coherent superposition of photon and magnon states is robustly sustained by the preserved anti-PT symmetry. The other type of singularity, arising from the dissipative coupling of two antiresonances, is an unconventional bound state in the continuum (BIC). At the settings of BICs, the coupled system exhibits infinite discontinuities in the group delay. We find that both singularities coexist at the equator of the Bloch sphere, which reveals a unique hybrid state that simultaneously exhibits the maximal coherent superposition and slow light capability.
