Abstract
Efficient monitoring of production performance is crucial for ensuring safe operations and enhancing the economic benefits of the Iron and Steel Corporation. Although basic modeling algorithms and visualization diagrams are available in many scientific platforms and industrial applications, there is still a lack of customized research in production performance monitoring. Therefore, this article proposes an interactive visual analytics approach for monitoring the heavy-plate production process (iHPPPVis). Specifically, a multicategory aggregated monitoring framework is proposed to facilitate production performance monitoring under varying working conditions. In addition, A set of visualizations and interactions are designed to enhance analysts' analysis, identification, and perception of the abnormal production performance in heavy-plate production data. Ultimately, the efficacy and practicality of iHPPPVis are demonstrated through multiple evaluations.

Abstract
That certain preconceptual paternal exposures reprogram the developmental phenotypic plasticity in future generation(s) has conceptualized the "paternal programming of offspring health" hypothesis. This transgenerational effect is transmitted primarily through sperm epigenetic mechanisms-DNA methylation, non-coding RNAs (ncRNAs) and associated RNA modifications, and histone modifications-and potentially through non-sperm-specific mechanisms-seminal plasma and circulating factors-that create 'imprinted' memory of ancestral information. The epigenetic landscape in sperm is highly responsive to environmental cues, due to, in part, the soma-to-germline communication mediated by epididymosomes. While human epidemiological studies and experimental animal studies have provided solid evidences in support of transgenerational epigenetic inheritance, how ancestral information is memorized as epigenetic codes for germline transmission is poorly understood. Particular elusive is what the downstream effector pathways that decode those epigenetic codes into persistent phenotypes. In this review, we discuss the paternal reprogramming of offspring phenotype and the possible underlying epigenetic mechanisms. Cracking these epigenetic mechanisms will lead to a better appreciation of "Paternal Origins of Health and Disease" and guide innovation of intervention algorithms to achieve 'healthier' outcomes in future generations. All this will revolutionize our understanding of human disease etiology.

Abstract
Serine is a metabolite with ever-expanding metabolic and non-metabolic signaling attributes. By providing one‑carbon units for macromolecule biosynthesis and functional modifications, serine and serine metabolism largely impinge on cellular survival and function. Cancer cells frequently have a preference for serine metabolic reprogramming to create a conducive metabolic state for survival and aggressiveness, making intervention of cancer-associated rewiring of serine metabolism a promising therapeutic strategy for cancer treatment. Beyond providing methyl donors for methylation in modulation of innate immunity, serine metabolism generates formyl donors for mitochondrial tRNA formylation which is required for mitochondrial function. Interestingly, fully developed neurons lack the machinery for serine biosynthesis and rely heavily on astrocytic l-serine for production of d-serine to shape synaptic plasticity. Here, we recapitulate recent discoveries that address the medical significance of serine and serine metabolism in malignancies, mitochondrial-associated disorders, and neurodegenerative pathologies. Metabolic control and epigenetic- and posttranslational regulation of serine metabolism are also discussed. Given the metabolic similarities between cancer cells, neurons and germ cells, we further propose the relevance of serine metabolism in testicular homeostasis. Our work provides valuable hints for future investigations that will lead to a deeper understanding of serine and serine metabolism in cellular physiology and pathology.

Abstract
Retinoic acid (RA), the derivative of vitamin A/retinol, is a signaling molecule with important implications in health and disease. It is a well-known developmental morphogen that functions mainly through the transcriptional activity of nuclear RA receptors (RARs) and, uncommonly, through other nuclear receptors, including peroxisome proliferator-activated receptors. Intracellular RA is under spatiotemporally fine-tuned regulation by synthesis and degradation processes catalyzed by retinaldehyde dehydrogenases and P450 family enzymes, respectively. In addition to dictating the transcription architecture, RA also impinges on cell functioning through non-genomic mechanisms independent of RAR transcriptional activity. Although RA-based differentiation therapy has achieved impressive success in the treatment of hematologic malignancies, RA also has pro-tumor activity. Here, we highlight the relevance of RA signaling in cell-fate determination, neurogenesis, visual function, inflammatory responses and gametogenesis commitment. Genetic and post-translational modifications of RAR are also discussed. A better understanding of RA signaling will foster the development of precision medicine to improve the defects caused by deregulated RA signaling.

Abstract
IgG4-related disease (IgG4-RD) is a chronic inflammation with fibrosis. About 30% to 40% of patients with IgG4-RD are complicated with atopic manifestations as allergic rhinitis and asthma, usually with elevated serum total immunoglobulin E and peripheral blood eosinophils, which are also of some value for predicting disease activity and relapse. Similar to allergic diseases, activation of type 2 inflammation is also observed in the pathogenesis of IgG4-RD, and eosinophils, basophils, mast cells, thymic stromal lymphopoietin, IL-33, IL-4, IL-5, and IL-13 all participate in the pathogenesis of IgG4-RD. Studies of susceptible genes showed that IgG4-RD and allergic disease shared the same susceptible genes. Monoclonal antibodies targeting type 2 inflammation pathway may become a novel choice for IgG4-RD treatment.

Abstract
Objective: To investigate the incidence and risk factors of systemic allergic reactions induced by subcutaneous immunotherapy (SCIT) in patients undergoing SCIT injections in Peking Union Medical College Hospital (PUMCH). Methods: This is a single center retrospective cohort study. Using the outpatient information system of PUMCH, the demographic information and injection-related reaction data of patients undergoing SCIT injection in Allergy Department of PUMCH from December 2018 to December 2022 were retrospectively analyzed to count the incidence and risk factors of systemic allergic reactions caused by SCIT. Mann-Whitney nonparametric test or chi-square test was used for single-factor analysis, and multiple logistic regression was used for multiple-factor analysis. Results: A total of 2 897 patients received 18 070 SCIT injections in Allergy Department during the four years, and 40 systemic allergic reactions occurred, with the overall incidence rate of 0.22%. The incidence of systemic allergic reaction was 0.37% when using imported dust mite preparation and 0.15% when using domestic multi-component allergen preparation. The risk factors significantly related with SCIT-induced systemic allergic reactions in patients using imported dust mite preparation were age less than 18 years old (OR=3.186,95%CI: 1.255-8.085), highest injection concentration (OR value could not be calculated because all patients with systemic reactions were injected with highest concentration), and large local reaction in previous injection (OR=22.264,95%CI: 8.205-60.411). The risk factors for SCIT-induced systemic allergic reactions in patients using domestic allergen preparation were 5 or more types of allergens (OR=3.455,95%CI: 1.147-10.402), highest injection concentration (OR=3.794,95%CI: 1.226-11.740) and large local reaction in previous injection (OR=63.577,95%CI: 22.248-181.683). However, SCIT injection in pollen allergic patients during the pollen season did not show a correlation with systemic allergic reaction. Conclusion: The incidence of SCIT-induced systemic allergic reactions was low in the Chinese patient population of this study. Patients with one or more risk factors, such as multiple allergen injection, highest injection concentration, large local reaction in previous injection, should be given high attention and vigilance against systemic allergic reactions.

Abstract
Pollen food allergy syndrome (PFAS) is an IgE-mediated allergic reaction that occurs when some pollinosis patients ingest certain plant-derived food that contains cross-reactive allergenic components. PFAS is prevalent in both children and adult pollinosis patients. In most cases, PFAS symptoms are confined to the oropharynx and occur within several minutes after oral contact with food. Therefore, PFAS has been also referred as oral allergy syndrome (OAS). A small proportion of PFAS patients would experience systemic symptoms or anaphylaxis. Currently, the diagnosis of PFAS is mainly based on clinical history and allergic tests [skin prick tests and(or) serum specific IgE tests]. Oral provocation tests are used to verify atypical patients. Component-resolved diagnosis is essential for further precise diagnosis and treatment. Management options for PFAS include lifestyle adjustment, symptomatic medication, and immunotherapy. The efficacy and appropriate population for immunotherapy need further investigation. This article aims to update the knowledge on epidemiology, pathogenesis and clinical management of PFAS, thereby enhancing clinicians' understanding as well as treatment progress of this disease entity.

Abstract
Objective: To analyze the clinical characteristics of children with IgE-mediated cow's milk protein allergy (CMPA) and provide a basis for disease management and prevention. Methods: A cross-sectional study was conducted to analyze 142 children aged 0-12 years who were diagnosed with IgE-mediated CMPA in Capital Institute of Pediatrics Affiliated Children's Hospital from 2020 to 2022. There were 79 males (55.6%) and 63 females (44.4%), with an average age of 14 (8, 27) months. 61 cases (43.0%) were in the <1-year-old group, 54 cases (38.0%) in the 1-3-year-old group, and 27 cases (19.0%) in the >3-year-old group. Data on demographic data, clinical manifestations, mean wheel diameter of skin prick test and serum specific IgE level were collected. The serum cow's milk protein sIgE and component sIgE were measured by ImmunoCAP fully automated system of fluorescence enzyme-linked immunosorbent assay, and statistically analyzed using chi-square test, nonparametric tests, correlation. Results: Cutaneous symptoms were the first and most frequent in 142 children (97.9%, 139/142 cases), followed by digestive (29.6%, 42/142 cases) and respiratory symptoms (27.5%, 39/142 cases).The proportion of children with respiratory symptoms after consuming cow's milk was significantly higher in the>3 years age group than those in the infant and toddler groups(66.7% vs 19.7%,χ2=18.396,P<0.01;66.7% vs 16.7%,χ2=20.250,P<0.01), and the symptoms involving ≥3 systems were also significantly higher than those in the other two groups(37.0% vs 13.1%,χ2=6.597,P<0.05;37.0% vs 7.4%,χ2=12.120,P<0.01). The average cow's milk SPT diameter and serum sIgE levels in the>3 years age group were significantly higher than those in the infant and toddler groups (Z=-4.682, P<0.01; Z=-3.498, P<0.01); (Z=-4.463, P<0.01; Z=-6.463, P<0.01). The most common cow's milk component protein were β-lactoglobulin(65.1%,56/86 cases) and casein (57.0%, 49/86 cases). Multiple-sensitization rate of the patients were 54.9%. Egg white (43.7%, 62/142 cases) was the most common co-sensitization food allergen while mold (12.7%, 18/142 cases) and weed pollen (12.7%, 18/142 cases) were the main co-sensitization aeroallergens. The proportion of multiple-sensitization to aeroallergens in the children group was the highest (51.9%, 14/27 cases), followed by the toddler group (29.6%, 16/54 cases), and the infant group was the least (3.3%, 2/61 cases). There was a significant difference among these three groups (χ2=7.476, P<0.05). Conclusion: Skin and mucosal symptoms are the most common in CMPA patients. The proportion of respiratory symptoms and multisystem involvement increased with age as well as the wheal diameter in skin test and serum sIgE level elevated. CMPA patients older than 3 years had the highest proportion of aeroallergen sensitization and airway allergic diseases.

Abstract
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected 660 million people and resulted in 6.7 million deaths. At present, a variety of risk factors related to the severity of COVID-19 have been identified, but whether allergic rhinitis and asthma will affect SARS-CoV-2 infection remains controversial. In general, there is no sufficient evidence to support that allergic rhinitis or asthma is a risk factor for increasing the rate of SARS-CoV-2 infection or aggravating the disease. Some studies even show that atopy may be a protective factor to alleviate SARS-CoV-2 infection, which is related to the decreased expression of angiotensin-converting enzyme 2, the receptor required for SARS-CoV-2 to enter cells, in atopic individuals. This paper reviews the influence of the severity and treatment of allergic rhinitis and asthma on SARS-CoV-2 infection, in order to provide some references for establishing strategies for prevention, risk stratification and treatment of COVID-19.

Abstract
Cellular metabolites are ancient molecules with pleiotropic implications in health and disease. Beyond their cognate roles, they have signaling functions as the ligands for specific receptors and the precursors for epigenetic or posttranslational modifications. Lactate has long been recognized as a metabolic waste and fatigue product mainly produced from glycolytic metabolism. Recent evidence however suggests lactate is an unique molecule with diverse signaling attributes in orchestration of numerous biological processes, including tumor immunity and neuronal survival. The copious metabolic and non-metabolic functions of lactate mediated by its bidirectional shuttle between cells or intracellular organelles lead to a phenotype called "lactormone." Importantly, the mechanisms of lactate signaling, via acting as a molecular sensor and a regulator of NAD+ metabolism and AMP-activated protein kinase signaling, and via the newly identified lactate-driven lactylation, have been discovered. Further, we include a brief discussion about the autocrine regulation of efferocytosis by lactate in Sertoli cells which favoraerobic glycolysis. By emphasizing a repertoire of the most recent discovered mechanisms of lactate signaling, this review will open tantalizing avenues for future investigations cracking the regulatory topology of lactate signaling covered in the veil of mystery.

Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV) is a highly contagious disease that affects the global pig industry. To understand mechanisms of susceptibility/resistance to PRRSV, this study profiled the time-serial white blood cells transcriptomic and serum metabolomic responses to PRRSV in piglets from a crossbred population of PRRSV-resistant Tongcheng pigs and PRRSV-susceptible Large White pigs. Gene set enrichment analysis (GSEA) illustrated that PRRSV infection up-regulated the expression levels of marker genes of dendritic cells, monocytes and neutrophils and inflammatory response, but down-regulated T cells, B cells and NK cells markers. CIBERSORT analysis confirmed the higher T cells proportion in resistant pigs during PRRSV infection. Resistant pigs showed a significantly higher level of T cell activation and lower expression levels of monocyte surface signatures post infection than susceptible pigs, corresponding to more severe suppression of T cell immunity and inflammatory response in susceptible pigs. Differentially expressed genes between resistant/susceptible pigs during the course of infection were significantly enriched in oxidative stress, innate immunity and humoral immunity, cell cycle, biotic stimulated cellular response, wounding response and behavior related pathways. Fourteen of these genes were distributed in 5 different QTL regions associated with PRRSV-related traits. Chemokine CXCL10 levels post PRRSV infection were differentially expressed between resistant pigs and susceptible pigs and can be a promising marker for susceptibility/resistance to PRRSV. Furthermore, the metabolomics dataset indicated differences in amino acid pathways and lipid metabolism between pre-infection/post-infection and resistant/susceptible pigs. The majority of metabolites levels were also down-regulated after PRRSV infection and were significantly positively correlated to the expression levels of marker genes in adaptive immune response. The integration of transcriptome and metabolome revealed concerted molecular events triggered by the infection, notably involving inflammatory response, adaptive immunity and G protein-coupled receptor downstream signaling. This study has increased our knowledge of the immune response differences induced by PRRSV infection and susceptibility differences at the transcriptomic and metabolomic levels, providing the basis for the PRRSV resistance mechanism and effective PRRS control.

Abstract
Primary immunodeficiency diseases (PID) is a congenital disease caused by single gene germline mutation related to the immune system. PID patients have immune dysregulation, and are susceptible to infectious diseases, autoimmune diseases, autoimmune diseases, allergic diseases, and malignant tumors. The first symptom of some PID patients is atopic disease, therefore they go to the department of allergy, department of pediatrics and other relevant departments. How to identify and diagnose PID in allergic patients, to reduce diagnosis delay and prevent disease aggravation are the abilities that allergists, pediatricians, and doctors in other relevant departments need to master. This article summarizes the warning signs of PID in allergic patients and the mechanism of allergy combined with PID, and then summarizes the common types of PID in allergic patients, the evaluation, treatment and prevention in patients with PID and allergy.

Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV) can replicate its RNA genome in endoplasmic reticulum (ER) and utilize ER to facilitate its assembly and maturation. To maintain ER homeostasis, host cells initiate reticulophagy (known as ER-phagy) to effectively digest the stressed ER. In this study, we found that PRRSV infection subverted ER-phagy by downregulating ER-phagy receptor FAM134B. PRRSV-induced miR-142-5p directly targeted FAM134B and significantly promoted PRRSV replication. Meanwhile, siRNA-mediated depletion of FAM134B protein and overexpression of FAM134B mutant protein significantly disrupted ER-phagy and facilitated PRRSV replication. Furthermore, our results showed that FAM134B-mediated ER-phagy activated type I interferon signaling to inhibit PRRSV replication. Overall, this study reveals the important role of ER-phagy in PRRSV replication in a FAM134B-dependent manner. Our findings provide an insight into the pathogenesis of PRRSV and offer a theoretical basis for further development of antiviral therapeutic targets.

Abstract
Simple Summary The gut microbiota could directly induce immune responses and affect the health of the host. In this study, we assessed changes in the gut microbiota of resistant segregated phenotypic pigs under Porcine Reproductive and Respiratory Syndrome Virus exposure. The results showed that the resistance of pigs was related to the composition of gut microbiota. The quantity and relative abundance of probiotics in resistant individuals positively affected host immunity and growth performance, whereas high levels of pathogenic bacteria in susceptible individuals were associated with poorer clinical outcomes. The results of this study suggest that gut microbiota may serve as an effective probiotic resource to provide new methods for PRRS prevention and treatment. Abstract Porcine Reproductive and Respiratory Syndrome (PRRS) is one of the serious infectious diseases that threatens the swine industry. Increasing evidence shows that gut microbiota plays an important role in regulating host immune responses to PRRS virus (PRRSV). The aim of this study was to investigate gut microbiota difference between PRRSV-resistant pigs and PRRSV-suspectable pigs derived from a Tongcheng pigs and Large White pigs crossed population. PRRSV infection induces an increase in the abundance and diversity of gut microbiota. Correlation analysis showed that 36 genera were correlated with viral loads or weight gain after PRRSV infection. Prevotellaceae-NK3B31-group, Christensenellaceae-R7-group, and Parabacteroides were highly correlated with both viral load and weight gain. Notably, the diversity and abundance of beneficial bacteria such as Prevotellaceae-NK3B31-group was high in resistant pigs, and the diversity and abundance of pathogenic bacteria such as Campylobacter and Desulfovibrio were high in susceptible pigs. Gut microbiota were significantly associated with immune function and growth performance, suggesting that these genera might be related to viremia, clinical symptoms, and disease resistance. Altogether, this study revealed the correlation of gut microbiota with PRRSV infection and gut microbiota interventions may provide an effective prevention against PRRSV infection.

Abstract
Anaphylaxis to perioperative drugs has an insidious and rapid onset, can be life-threatening, and often results in the suspension of surgery. Neuromuscular blocking agents (NMBAs) are currently considered to be the most common cause of anaphylactic reactions among anesthetic drugs. With the increasing amount of anesthesia and surgery in the world, there are more and more NMBAs use, and the corresponding allergic risk is also increasing. With the use of NMBAs, their antagonists, such as neostigmine and sugammadex, are often used too, which have more and more allergy reports in clinical practice. Due to the complex mechanism of allergy caused by NMBAs and their antagonists, it is difficult to find out the culprit drug. The cross-reactivity between NMBAs is common, so it is often difficult to choose alternative drugs. This article summarized the epidemiology, pathological mechanisms, diagnostic methods and procedures, immediate treatment, and prevention strategies of anaphylaxis caused by these drugs.

Abstract
Objective: To analyze the characteristics of clinical distribution and change of aeroallergens in children with allergic diseases from 2015 to 2020. Methods: Children who visited Capital Institute of Pediatrics affiliated Children's Hospital, suspected of allergic diseases and received serum aeroallergens specific immunoglobulin E (sIgE) test were retrospectively enrolled (1 to 14 years old). sIgE was detected by Phadia1000 system with radioallergosorbent test fluorescent enzyme-linked immunoassay. The characteristics and change of the aeroallergens among the 6 years was analyzed. Enumeration data were expressed by percentage and categorical variables were compared by the independent samples t-test and Pearson χ2 test. Results: In total 4 608 tests (4 575 patients) of children were enrolled, the average age was (5.4±2.9) years old, with the median age of 5.0 years old. 3 176 were boys (68.9%), and 1 432 were girls (31.1%). 4 294 children were from the north of China (93.2%), 295 children were from the south of China (6.4%), and 19 children were from unknown regions (0.4%). In total the most common aeroallergen was mold mixture (1 956/4 457 tests, 43.9%) and Alternaria alternata (276/630 tests, 43.8%), followed by Artemisia (300/889 tests, 33.7%), Humulus scandens (12/38 tests, 31.6%) and grass mixture (909/2 874 tests, 31.6%). Among the 6 years, mold, grass pollen and tree pollen sensitization increased, and mold [38/130 (29.2%) vs 1 574/3 233 (48.7%)], grass pollen [11/77 (14.3%) vs 1 069/3 072 (34.8%)] increased significantly (χ2 was 18.953 and 49.559, respectively, P=0.000). Positive rate of tree pollen increased [1/10 (10.0%) vs 516/2 122 (24.3%)], but did not have statistical significance (χ²=1.111, P=0.292). Dust mite [36/146 (24.7%) vs 321/1 408 (22.8%)] and hair of pets [7/33 (21.2%) vs 321/1 408 (17.1%)] sensitization didn't change greatly (χ2 =0.258, P =0.611; χ2 =0.379, P =0.538). In 2015, the most common aeroallergens was mold (38/130, 29.2%), followed by dust mite (36/146, 24.7%), while in 2020, the most common aeroallergens was still mold (1 574/3 233, 48.7%), with grass pollen (1 069/3 072, 34.8%) and tree pollen (516/2 122, 24.3%) ranked after. Conclusion: Mold might be the most common aeroallergens in allergic children in Beijing area. With time went on, dust mite was gradually exceeded by grass pollen and tree pollen.

Abstract
Alternative polyadenylation (APA) is a widespread post-transcriptional regulation mechanism that increases the biological complexity of transcriptome and proteome. However, it is unclear whether APA regulation plays a role in genetic resistance to porcine reproductive and respiratory syndrome virus (PRRSV). Here, we reported genome-wide APA regulation of porcine alveolar macrophages in PRRSV-resistant Tongcheng (TC) pigs and PRRSV-susceptible Large White (LW) pigs upon PRRSV infection. Using 3' mRNA sequencing strategy, we detected 75 981 high-quality APA sites in porcine alveolar macrophages of TC and LW pigs. Furthermore, 1202 and 1089 differentially expressed APA sites, as well as 79 and 117 untranslated region-APA switching genes were identified in TC pigs and LW pigs upon PRRSV infection respectively. The APA events in TC pigs and LW pigs were involved in different biological pathways, while APA events in TC pigs are directly associated with the immune response to PRRSV infection. In addition, we identified genetic variations affecting polyadenylation signal between TC pigs and LW pigs. These findings would provide helpful information on APA regulation for further understanding of genetic resistance to PRRSV.

Abstract
Objective: The preseason prophylactic treatment of seasonal allergic rhinitis (AR) caused by pollens could alleviate AR symptoms during the pollen season. This study aimed to evaluate the effect of prophylaxis usage of suplatast tosilate on the life quality of AR patients in the pollen season, and investigate the potential mechanism of action through transcriptomic analysis. Methods: This is a randomized controlled study. AR patients allergic to weed pollens were recruited from Allergy Clinic of Peking Union Medical College Hospital from January 2020 to June 2020, and divided into prophylactic group who started to take suplatast tosilate as prophylaxis 2 weeks before the spread of weed pollens[n=10, 4 men and 6 women with age range of (34±6) years old] and control group who did not use any prophylactic treatment[n=24, 12 men and 12 women with age range of (33±9) years old]. The differences of age (t=0.381, P=0.706) and gender (χ²=0.595, P=0.715) distribution between the patients of two groups were not statistically significant. All the subjects filled in the rhinoconjunctivitis quality of life questionnaire (RQLQ) while onset of AR symptoms, and peripheral blood was drawn for transcriptomic analysis 1 month before and during the pollen season. Differences between groups were statistically analyzed through chi-square test and t test. Results: There was no significant difference in visual analogue scale of rhinitis symptom in the last pollen season between prophylactic group and control group[ 8.0 (6.4, 9.3) vs 7.3 (6.1, 8.0), Z=1.180, P=0.254]. The RQLQ score of prophylactic group was superior to that of control group in the weed pollen season (2.9±0.9 vs 3.7±0.9, t=-2.438, P=0.026). 210 differentially expressed genes of fold change ≥2 were identified, with 147 genes upregulated and 63 genes downregulated in the prophylactic group compared to the control group. Gene Ontology annotation showed that IL-12 and IL-23 related pathways were downregulated in prophylactic group (P=0.006 48). Polymerase Chain Reaction (PCR) verification of differentially expressed genes indicated that the relative expression level of HLA-G in prophylactic group was significantly lower than that in control group (0.23±0.19 vs 1.00±0.49,t=4.016, P=0.006). Conclusion: The prophylactic treatment of suplatast tosilate showed some benefit to the life quality of seasonal AR patients during the pollen season, and the potential mechanism might be related with the downregulation of IL-12 and IL-23 pathways and decreased expression of HLA-G.

Abstract
Objective: To investigate appropriate protocol of treatment modulation for seasonal allergic rhinitis (AR) patients, in order to promote the implementation of personalized medicine. Methods: Total of 124 AR patients allergic to cypress pollens were recruited from January to February 2020 in Department of Allergy in Peking Union Medical College Hospital, 43 males and 81 females with an average age of (41±9) years. The patients were divided into two groups with block randomization method. In the first group, treatment was modulated every two days according to the average daily rhinoconjunctivitis symptom score of the last two days (short-term symptom-score group); while in the second group, therapy regimen was adjusted every week based on the Allergic Rhinitis Control Test (ARCT) score of the last week (long-term ARCT group). The treatment level was up-regulated when the cypress pollen count increased and stayed at a high level (step-up pharmacotherapy stage); and treatment was down-regulated while the pollen count decreased (step-down pharmacotherapy stage). Daily symptom scores, medicine scores, and ARCT scores of the two groups were recorded and compared. Results: During the whole cypress pollen season, the daily rhinoconjunctivitis symptom score of short-term symptom-score group was significantly lower than that in long-term ARCT group(2.4±1.0 vs 2.7±1.0, P<0.01), and the difference between the two groups was more pronounced in the step-up pharmacotherapy stage than that in the step-down pharmacotherapy stage, while there was no statistical difference between the daily medicine scores of the two groups (P>0.05). During the pollen rising period, the ARCT score of short-term symptom-score group was significantly better than that of long-term ARCT group (21(19, 22) vs 20 (17, 21), P=0.049); while in the pollen peak period and decreasing period, the ARCT scores of the two groups showed no statistical difference (P>0.05). The proportion of incompliance with doctor's advice was higher in long-term ARCT group compared to that in short-term symptom-score group (30.1% vs 6.7%, P<0.001). Conclusion: The protocol of treatment modulation for seasonal AR patients allergic to pollens should be developed flexibly according to the variation trend of pollen allergen exposure, so as to implement the idea of personalized medicine.

Abstract
Currently, we are experiencing a true pandemic of a communicable disease by the virus SARS-CoV-2 holding the whole world firmly in its grasp. Amazingly and unfortunately, this virus uses a metabolic and endocrine pathway via ACE2 to enter our cells causing damage and disease. Our international research training programme funded by the German Research Foundation has a clear mission to train the best students wherever they may come from to learn to tackle the enormous challenges of diabetes and its complications for our society. A modern training programme in diabetes and metabolism does not only involve a thorough understanding of classical physiology, biology and clinical diabetology but has to bring together an interdisciplinary team. With the arrival of the coronavirus pandemic, this prestigious and unique metabolic training programme is facing new challenges but also new opportunities. The consortium of the training programme has recognized early on the need for a guidance and for practical recommendations to cope with the COVID-19 pandemic for the community of patients with metabolic disease, obesity and diabetes. This involves the optimal management from surgical obesity programmes to medications and insulin replacement. We also established a global registry analyzing the dimension and role of metabolic disease including new onset diabetes potentially triggered by the virus. We have involved experts of infectious disease and virology to our faculty with this metabolic training programme to offer the full breadth and scope of expertise needed to meet these scientific challenges. We have all learned that this pandemic does not respect or heed any national borders and that we have to work together as a global community. We believe that this transCampus metabolic training programme provides a prime example how an international team of established experts in the field of metabolism can work together with students from all over the world to address a new pandemic.

Abstract
Abstract
Background and purpose
Following myocardial infarction (MI), adverse fibrotic remodeling with extensive deposition of extracellular matrix (ECM) components has substantial consequences for the contractility of the ventricle finally leading to terminal heart failure (HF). Recently, inhibition of ECM-remodeling enzymes is discussed as potential treatment option for HF, especially following MI. The metalloprotease ADAM10 plays a crucial role in the development of the cardiovascular system and HF patients show elevated serum levels of the ADAM10 substrates CXCL16 and FasL. However, the causal role of ADAM10 in cardiovascular diseases has not been investigated. Here we evaluate the so far unknown role of ADAM10 in heart failure and after MI.
Methods and results
Our study capitalized from human atrial tissue biopsies, a cardiomyocyte-specific ADAM10 knockout (ADAM10 KO) mouse model as well as pharmacological ADAM10 inhibition following MI. ADAM10 expression analysis revealed elevated protein levels in HF patients compared to non-failing hearts. Upon MI, ADAM10 KO and pharmacological ADAM10 inhibition (GI254023X) significantly improved overall survival, significantly enhanced cardiac function (fractional area shortening - FAS, ejection fraction - EF) and significantly reduced infarct sizes. Compared to the high potential angiotensin receptor neprilysin inhibitor (ARNi) LCZ696, ADAM10 inhibition and combined ADAM10i/LCZ696 treatment resulted in preservation of cardiac function that was superior to sole LCZ696 treatment. Mechanistically, this functional improvement was due to reduced shedding of the ADAM10 substrate Notch1, induction of angiogenesis and an ADAM10-dependend inactivation of the NLRP3 inflammasome
Conclusion
Our data suggest that ADAM10 targeting is highly efficient for improving post-infarction cardiac function. Due to its overexpression in heart tissue of HF patients, ADAM10 could be a potential molecular target to improve therapy after MI. In terms of overall survival and pathophysiological remodeling following MI, our data suggest a greater potential of the ADAM10i/LCZ696 combinatorial therapy than sole LCZ696 treatment.

This study aimed to recruited allergic rhinitis patients caused by cypress pollens, and compare the step-down pharmacotherapy guided by pollen count and the maintaining therapy which keeps the previous medicine dose when the pollen count decreased. Method:This was a randomized, open-labelled, parallel control study. During the period after the pollen peak when the cypress pollen count decreased and stayed at a low level, allergic rhinitis patients were randomly divided into two groups. In the step-down group(n=67) medicine dose was reduced, while the maintaining group(n=68) kept taking the same dose as in the peak season. The rhinitis symptom score and medicine score of these two groups were recorded and compared. Result:The daily rhinitis symptom score of the step-down group showed no significant difference with the symptom score of the maintaining group, 2.45±0.32 vs 2.43±0.41, P=0.788. But the medicine score of step-down group(3.67±0.98) was significantly lower than that of maintaining group(4.78±0.70), P<0.001. The compliance of step-down group(80.6%) was also better than maintaining group(60.3%), P=0.014. However, in the subgroup of patients with severe rhinitis symptoms, the symptoms of patients taking step-down therapy tended to be more severe than those maintaining the same dose. Conclusion:During the later period of the pollen season when the pollen count was relatively low, the step-down pharmacotherapy guided by pollen count could reduce the medication use, increase the compliance of patients while controlling their rhinitis symptoms effectively. But this strategy might be more suitable for patients with milder symptoms, the severe rhinitis sufferers should be cautious before reducing their medicine dose.

Abstract
Objective:To investigate the sensitization spectrum and clinical features of children with adenoid hypertrophy and perennial rhinitis.Method:A total of 121 children with adenoidal hypertrophy and perennial rhinitis were enrolled in the ENT Department of the Children's Hospital of the Capital Institute of Pediatrics and the Allergy Department of Peking Union Medical College Hospital from July to October in 2017. Nasopharyngoscopy was performed, and specific IgE were measured by blood sampling, and the sensitization spectrum and clinical characteristics of the children were analyzed. Result: Adenoid hypertrophy combined with allergic rhinitis accounted for 64.5% of the total, mold sensitization was the most common, accounting for 78.2% of allergic rhinitis patients, including boys accounted for 67.2%, gender differences were statistically significant(P<0.05). Patients with allergic rhinitis had a more severe endoscopic appearance, with a higher proportion of 4 degree, accounting for 75.0% of the total number of children with 4 degree under the nasopharyngoscopy, and only 25.0% of children without defined allergens. There was a significant difference between this two groups(P<0.05). Conclusion: Allergic rhinitis is closely related to adenoid hypertrophy, and the effect of allergen on the clinical manifestations of patients with adenoid hypertrophy should be emphasized.

Abstract
Objective:To compare the efficacy and side effects of combined therapy with single-dose oral antihistamine and intranasal corticosteroid to monotherapy with double-dose oral antihistamine in the treatment of seasonal allergic rhinitis. Method:Eighty-two patients with seasonal allergic rhinitis caused by cypress pollen were enrolled in a randomized, parallel-group studycomparing 2 weeks therapy of either 10mg oral ebastine plus 200 μg intranasal mometasone furoate once daily (combined group) or 20 mg oral ebastine once daily (double-dose group) during the pollen season. Daily rhinoconjunctivitis symptom score and rescue medication use were recorded in both groups. After the treatment period, questionnaires were used to survey the side effects of medicines and dosage form preference of the patients. The levels of IL-6, IL-8 and TNF-α in the peripheral blood were measured before and after the therapy. Result:During the cypress pollen season, the daily rhinoconjunctivitis symptom score of the combined group (n=42, 3.7±0.4) was significantly lower than that of double-dose group (n=40, 4.5±0.5), P<0.001. The daily rescue medication score of the combined group (1.3±0.6) was also significantly lower than double-dose group(1.7±0.7), P<0.001. The daily medication cost of combined group was 7.08±0.33 Yuan, which was less than that of double-dose group (7.28±0.51 Yuan, P=0.002). There was no statistical difference in the rate of adverse reactions between the two groups. The peripheral levels of IL-6, IL-8 and TNF-α in two groups did not show significant difference at the end of therapy . Conclusion:The combined therapy with single-dose oral antihistamine and intranasal corticosteroid was superior to the monotherapy with double-dose oral antihistamine in the treatment of seasonal allergic rhinitis in our study.

Abstract
Numerous studies have demonstrated that microRNAs (miRNAs) play important roles in cell growth, apoptosis and spermatogenesis. Our previous study showed that miR-638 was differentially expressed in sexually immature and mature testes of Large White boars. Here we reported that sperm-associated antigen 1 (SPAG1) was a direct target gene of miR-638. Moreover, miR-638 inhibited cell proliferation and cell cycle, and promoted apoptosis of porcine immature Sertoli cells. Key genes including phosphorylated phosphatidylinositide 3-kinases (p-PI3K) and phosphorylated serine/ threonine kinase (p-AKT) in PI3K/AKT pathway as well as cell cycle factors including c-MYC, cyclin-D1 (CCND1), cyclin-E1 (CCNE1) and cyclin-dependent kinase 4 (CDK4) were all significantly down-regulated after overexpression of miR-638 or RNAi of SPAG1. Notably, mRNA levels of SRY-related HMG-box 2 (SOX2) and POU domain, class 5, transcription factor 1 (POU5F1) essential for spermatogonia proliferation were significantly suppressed in SPAG1 siRNA- transfected ST cells. This study suggests that miR-638 regulates immature Sertoli cell growth and apoptosis by targeting SPAG1 gene which can indirectly inactivate PI3K/AKT pathway, and plays roles in pig spermatogenesis.

Abstract
This study sought to investigate the clinical efficacy of arthroscopic refreshing treatment of anterior cruciate ligament (ACL) injury combined with stable medial meniscus ramp injury. Sixty-eight patients treated between January 2010 and January 2014 were included, and their clinical data were retrospectively analyzed. All patients, after being treated using ACL reconstruction, were divided into 2 groups according to meniscus injury treatment method. The observation group (31 cases) was treated by arthroscopic refreshing, which removed the tissue on both sides of the tear edge using a cutting knife, while the control group (37 cases) was treated using Fast-fix sutures. All patients were followed up for at least 24 months. Surgical duration, postoperative function recovery time, and hospital stay for patients in the observation group were significantly shorter than for those of the control group (P⟨0.05). Both groups showed significant post-operative improvement for Lysholm scores, IKDC scores, and average knee range of motion at 12 and 24 months post-operation (P⟨0.05), but no significant differences between groups were observed (P⟩0.05). Regarding the difference in movement range between the healthy and injured sides, both groups showed significant decrease post-operation (P⟨0.05). Ultimately, there was no significant difference in the recovery of ramp damage and objective symptoms between the two groups (P⟩0.05). Arthroscopic refreshing treatment of patients with anterior cruciate ligament injury combined with stable ramp lesion can achieve similar clinical curative effects as the Fast-fix suture, thereby providing a simple alternative for patient treatment worth popularizing.

Abstract
Objective:Pyruvate is a key intermediate in several metabolic pathways of human body Sodium pyruvate possesses anti-oxidation and anti-inflammatory effects, which make it a possible novel therapy for allergic rhinitis. However, the relevant clinical research is rare. The aim of the present study is to evaluate the treatment effect of sodium pyruvate nasal spray on allergic rhinitis.Method:This was a randomized, parallel-group, single-center study, and 53 adult patients with seasonal allergic rhinitis caused by Artemisia pollen were recruited. In the pollen season, all the participants were given corticosteroid nasal spray of standard dose for two weeks, and during the next two weeks they were randomized to treatment group (n = 23) taking nasal sodium pyruvate, and control group (n = 30) without sodium pyruvate. Daily rhinoconjunctivitis symptom score and daily rescue medication score were analyzed. Also the fraction of exhaled nitric oxide of the upper airway was measured before and after the treatment of sodium pyruvate. Result:The demographic characteristics and baseline disease severity were not significantly different between the treatment group and control group. Both the daily symptom score (1.4±0.6 vs 1.7±0.4, P= 0.006) and rescue medication score (4.8±1.2 vs 5.8±1.2, P= 0.000) of the treatment group was significantly lower than the scores of control group. In addition, nasal fraction of exhaled nitric oxide of the treatment group (596.3±134.6)ppb tended to be lower than control group (709.6±311.3)ppb, although the difference was not significant, P= 0.408. Conclusion:Sodium pyruvate nasal spray was effective in attenuating the rhinoconjunctivitis symptoms and reducing the rescue medication use of allergic rhinitis patients. The application value and mechanism of action of sodium pyruvate are worth further studying.

Abstract
A growing number of reports have revealed that microRNAs (miRNAs) play critical roles in spermatogenesis. Our previous study showed that miR-762 is differentially expressed in immature and mature testes of Large White boars. Our present data shows that miR-762 directly binds the 3′ untranslated region (3′UTR) of ring finger protein 4 (RNF4) and down-regulates RNF4 expression. A single nucleotide polymorphism (SNP) in the RNF4 3′UTR that is significantly associated with porcine sperm quality traits leads to a change in the miR-762 binding ability. Moreover, miR-762 promotes the proliferation of and inhibits apoptosis in porcine immature Sertoli cells, partly by accelerating DNA damage repair and by reducing androgen receptor (AR) expression. Taken together, these findings suggest that miR-762 may play a role in pig spermatogenesis by regulating immature Sertoli cell growth.

Abstract
GTPase sperm-associated antigen 1 is studied in the context of mammalian oogenesis and female fertility. It is found to have a role in oocyte meiotic execution via its involvement in AMPK and MAPK signaling pathways. In mammals, a finite population of oocytes is generated during embryogenesis, and proper oocyte meiotic divisions are crucial for fertility. Sperm-associated antigen 1 (SPAG-1) has been implicated in infertility and tumorigenesis; however, its relevance in cell cycle programs remains rudimentary. Here we explore a novel role of SPAG-1 during oocyte meiotic progression. SPAG-1 associated with meiotic spindles and its depletion severely compromised M-phase entry (germinal vesicle breakdown [GVBD]) and polar body extrusion. The GVBD defect observed was due to an increase in intraoocyte cAMP abundance and decrease in ATP production, as confirmed by the activation of AMP-dependent kinase (AMPK). SPAG-1 RNA interference (RNAi)–elicited defective spindle morphogenesis was evidenced by the dysfunction of γ-tubulin, which resulted from substantially reduced phosphorylation of MAPK and irregularly dispersed distribution of phospho-MAPK around spindles instead of concentration at spindle poles. Significantly, actin expression abruptly decreased and formation of cortical granule–free domains, actin caps, and contractile ring disrupted by SPAG-1 RNAi. In addition, the spindle assembly checkpoint remained functional upon SPAG-1 depletion. The findings broaden our knowledge of SPAG-1, showing that it exerts a role in oocyte meiotic execution via its involvement in AMPK and MAPK signaling pathways.

Abstract
Swine testicular (ST) cell line is isolated from swine fetal testes and has been widely used in biomedical research fields related to pig virus infection. However, the potential benefit and utilization of ST cells in boar reproductive studies has not been fully explored. As swine fetal testes mainly contain multiple types of cells such as Leydig cells, Sertoli cells, gonocytes, and peritubular myoid cells, it is necessary to clarify the cell type of ST cell line. In this study, we identified ST cell line was a collection of Sertoli cells by analyzing the unique morphological characteristic with satellite karyosomes and determining the protein expression of two markers (androgen-binding protein, ABP; Fas ligand, FASL) of Sertoli cells. Then ST cells were further confirmed to be immature Sertoli cells by examining the expression of three markers (anti-Mullerian hormone, AMH; keratin 18, KRT18; follicle-stimulating hormone receptor, FSHR). In conclusion, ST cells are a collection of immature Sertoli cells which can be good experimental materials for the researches involved in Sertoli cell functions and maturation, or even in boar reproductions.

Abstract
BACKGROUND Hereditary angioedema is a rare autosomal dominant disease, and its correlation between genotype and phenotype seems not to exist. So far, there are very few studies on Chinese population. We aimed to establish a Chinese genetic database of hereditary angioedema and investigated the potential correlation between genotype and phenotype. METHOD All the eight exons and intron-exon boundaries of C1 inhibitor gene were detected in 48 unrelated families with HAE. The correlations between genotype and clinical parameters were evaluated by R statistical software. RESULTS Thirty-five different mutations (25 of them were novel) and 7 SNPs (3 of them were novel) were identified. Significant difference was found in the level of C1 inhibitor antigen (P = 0.01793) between different groups of mutational types. The correlation between different groups of mutational types and the level of C1 inhibitor antigen (0.5047, P = 0.00027) was significant. The different groups of mutational types showed neither difference nor correlations of clinical parameters (severity score and the level of C1 inhibitor function). CONCLUSION It appears that nonsense, frameshift, and mutations on Arg466 can cause lower level of C1 inhibitor antigen than missense and in-frame mutations; however, it does not affect severity of symptoms.

Abstract
STUDY DESIGN A new mineralized collagen matrix combined with or without growth factor was used for the posterolateral spinal fusion in the rabbit lumbar spine. OBJECTIVES The availability of a new osteoconductive matrix with or without recombinant osteoinductive growth factors offers a possible alternative to the use of autogenous bone for grafting indications. This study evaluated the bone-forming activity of the biomimetic matrix: nano-hydroxyapatite/collagen/polylactic acid (nHAC/PLA) combined without or with recombinant human bone morphogenetic protein-2 (rhBMP-2) in a rabbit posterolateral spinal fusion. SUMMARY OF BACKGROUND DATA Many bone grafting materials such as titanium alloy, ceramics, and polymers were used to repair bony defects. However, each has specific disadvantaged. The permanent implantation still has possibility to be eroded in vivo, which is caused by late breakdown and abscess formation. The acidic outcome of polymer biodegradation was also negatively affected in the later-stage results of bone repair. It needed a promising material for an alternative to the use of autogenous bone for grafting indications. MATERIALS AND METHODS Sixty-four rabbits were randomly divided into four groups: autologous iliac crest bone group (ACB), nHAC/PLA composite group (nHAC/PLA), autologous iliac crest bone mixed with nHAC/PLA composite group (ACB + nHAC/PLA), nHAC/PLA composite with recombinant human BMP-2 group (nHAC/PLA + rhBMP-2). The lumbar intertransverse process fusions were assessed by manual palpation, radiographic, histologic, and mechanical strength, and scanning electronic microscopy (SEM) in a 10-week observation. RESULTS Optimal formulations of the ACB + nHAC/PLA and nHAC/PLA + rhBMP-2 groups were shown to perform similar to ACB in both the fusion ratio and mechanical strength in the 6 and 10 weeks after surgery. From the microstructure analysis of the samples, there was no negative effect when the compound implanted this composite with autogenous iliac crest, and there was also new bone-like tissue formation implanted this composite without combined rhBMP-2 early at the second week after surgery. CONCLUSIONS This study shows the effective results of nHAC/PLA in rabbit posterolateral spinal fusion combined with rhBMP-2. It is an alternative method to autograft by compounding this osteoconductive matrix with growth factors.

Abstract
Primary cultures or established cell lines of vertebrates are commonly used to analyse the mutagenic, embryotoxic or teratogenic potential of environmental factors, drugs and xenobiotics in vitro. However, these cellular systems do not include developmental processes from early embryonic stages up to terminally differentiated cell types. An alternative approach has been offered by permanent lines of pluripotent stem cells of embryonic origin, such as embryonic carcinoma (EC), embryonic stem (ES) and embryonic germ (EG) cells. The undifferentiated stem cell lines are characterized by nearly unlimited self-renewal capacity and have been shown to differentiate in vitro into cells of all three primary germ layers. Pluripotent embryonic stem cell lines recapitulate cellular developmental processes and gene expression patterns of early embryogenesis during in vitro differentiation, data which are summarized in this review. In addition, recent studies are presented which investigated mutagenic, cytotoxic and embryotoxic effects of chemical substances using in vitro systems of pluripotent embryonic stem cells. Furthermore, an outlook is given on future molecular technologies using embryonic stem cells in developmental toxicology and embryotoxicology.

Abstract
The activation of nuclear factor kappaB (NF-kappa B) plays a pivotal role in the regulation of tumor necrosis factor (TNF)-mediated apoptosis. However, little is known about the regulation of TNF-mediated apoptosis by other signaling pathways or growth factors. Here, unexpectedly, we found that bone morphogenetic protein (BMP)-2 and BMP-4 inhibited TNF-mediated apoptosis by inhibition of caspase-8 activation in C2C12 cells, a pluripotent mesenchymal cell line that has the potential to differentiate into osteoblasts depending on BMP stimulation. Utilizing both a trans-dominant IkappaBalpha inhibitor of NF-kappaB expressed in C2C12 cells and IkappaB kinase beta-deficient embryonic mouse fibroblast, we show that BMP-mediated survival was independent of NF-kappaB activation. Rather, the antiapoptotic activity of BMPs functioned through the Smad signaling pathway. Thus, these findings provide the first report of a BMP/Smad signaling pathway that can inhibit TNF-mediated apoptosis, independent of the prosurvival activity of NF-kappaB. Our results suggest that BMPs not only stimulate osteoblast differentiation but can also promote cell survival during the induction of bone formation, offering new insight into the biological functions of BMPs.

Abstract
Embryonic stem (ES) cells are able to differentiate in vitro into endodermal, mesodermal, and ectodermal cell types. However. the spontaneous development of neuronal cells from ES cells is rather limited. Therefore, specific protocols to increase the differentiation of neuronal cells have been established, such as retinoic acid (RA) induction and lineage selection of neuronal cells. High concentrations of RA resulted in efficient neuronal differentiation paralleled by the expression of tissue-specific genes, proteins, ion channels, and receptors in a developmentally controlled manner. Because the developmental pattern and survival capacity of RA-induced neuronal cells were limited, specific differentiation protocols by lineage selection of neuronal cells have been established using growth and extracellular matrix factors. After formation of cells of the three primary germ layers, mesodermal differentiation was inhibited by serum depletion, and neural precursor cells were generated by addition of basic fibroblast growth factor, followed by differentiation induction by neuronal differentiation factors. Further application of survival-promoting factors such as neurotrophic factors and cytokines at terminal stages resulted in a significant increase, survival, and maintenance of dopaminergic neurons. In the future, these cellular systems will be applicable: (1) for studying commitment and neuronal specification in vitro, (2) as pharmacological assays for drug screening, and (3) for the selective isolation of differentiated neuronal cells which may be used as a source for cell and tissue grafts.
