Abstract
Oral and maxillofacial space infections (OMSI) are common diseases of the facial region involving fascial spaces. Recently, OMSI shows trends of multi drug-resistance, severe symptoms, and increased mortality. OMSI treatment principles need to be updated to improve the cure rate. Based on the clinical experiences of Chinese experts and with the incorporation of international counterparts' expertise, the principles of preoperative checklist, interpretation of examination results, empirical medication principles, surgical treatment principles, postoperative drainage principles, prevention strategies of wisdom teeth pericoronitis-related OMSI, blood glucose management, physiotherapy principles, Ludwig's angina treatment and perioperative care were systematically summarized and an expert consensus on the diagnosis and treatment of OMSI was reached. The consensus aims to provide criteria for the diagnosis and treatment of OMSI in China so as to improve the level of OMSI treatment.

Abstract
Objective: To analyze the prevalence and the related factors of dyslipidemia in 21-hydroxylase deficiency (21-OHD) patients. Methods: A total of 205 patients with 21-OHD were recruited in Peking Union Medical College Hospital from January 2016 to January 2018. The basic information, glucocorticoid replacement therapy, and laboratory examination results of patients were obtained from medical records. The genotypes of CYP21A2 were identified by Sanger sequencing and multiplex ligation dependent probe amplification. The prevalence of dyslipidemia among 21-OHD patients, basic information and related hormone levels of 21-OHD patients with different status of blood lipid were described. Logistic regression model was used to analyze the related factors of dyslipidemia in 21-OHD patients. Results: The age of subjects was 17.0 (8.3, 25.0) years old, including 51 males (24.9%). According to CYP21A2 genotypes, there were 16 cases in Null group, 26 cases in Group A, 105 cases in group B, 27 cases in group C, and 31 cases in group D. The incidence of dyslipidemia was 29.3% (60/205), among which 37.3% (19/51) in male and 26.6% (41/154) in female patients, respectively. The M (Q1, Q3) of total cortisol level (nmol/L) and body mass index (kg/m2) of male 21-OHD patients with dyslipidemia were 0.17 (0.06, 0.35) and 25.76 (17.01, 30.45), respectively, which were higher than those with ortholiposis [0.04 (0.02, 0.21) and 18.83 (16.53, 23.88)] (all P<0.05). The M (Q1, Q3) of progesterone level (nmol/L), body mass index (kg/m2) and age (years) of female 21-OHD patients with dyslipidemia were 74.40 (50.97, 98.52), 23.09 (21.78, 27.78) and 23.00 (16.50, 28.00), respectively, which were higher than those with ortholiposis [52.81 (33.41, 68.85), 21.55 (18.63, 25.71) and 18.00 (9.50, 25.00)] (all P<0.05). The risk of dyslipidemia increased by 5.0% [OR (95%CI): 1.05 (1.01, 1.09)] for every 1 nmol/L increase of progesterone. Conclusion: The incidence of dyslipidemia is high in 21-OHD patients, and progesterone level is positively correlated with dyslipidemia.

Abstract
BACKGROUND Severity of negative symptoms has been associated with poor functioning, cognitive deficits, and defeatist beliefs in schizophrenia patients. However, one area that remains understudied is persistent negative symptoms (PNS). Negative symptoms, including PNS, have been observed in those at clinical high-risk (CHR) for psychosis. The aim of this study was to determine if PNS were associated with functioning, neurocognition, and defeatist beliefs in a CHR sample. METHOD CHR participants (n = 764) were recruited for the North American Prodrome Longitudinal Study. Negative symptoms were rated on the Scale of Psychosis-risk Symptoms. Generalized linear mixed models for repeated measures were used to examine changes over time between and within groups (PNS vs non-PNS). RESULTS The PNS group (n = 67) had significant deficits in functioning at baseline, 6, 12, 18, and 24-months compared to the non-PNS group (n = 673). Functioning improved over time in the non-PNS group, while functioning in the PNS group remained relatively stable and poor over a two-year period. A consistent trend emerged demonstrating higher defeatist beliefs in the PNS group; however, this result was lost when controlling for persistent depressive symptoms. There were no significant differences between the groups on neurocognition, social cognition, and transition to psychosis. CONCLUSIONS PNS exist in youth at CHR for psychosis, resulting in significant and persistent functional impairment, which remains when controlling for persistent depressive symptoms. PNS remain even in CHR youth who do not transition to psychosis. Thus, PNS may represent an unmet therapeutic need in CHR populations for which there are currently no effective treatments.

Abstract
1. Innate immunity provides the first line of defence against pathogenic organisms through a myriad of germline encoded receptors called pattern-recognition receptors (PRRs). Toll-like receptor (TLR) 3, as an important member of PRRs, is indispensable for host defence against viral infection by recognising virus-derived RNAs. However, little is known about the structure and function of TLR3 in ducks (Anas platyrhynchos), a natural host for the avian influenza virus.2. This study cloned the full-length cDNA of duck TLR3 using reverse transcription polymerase chain reaction (RT-PCR) with rapid amplification of cDNA ends (RACE). The cDNA sequence of duck TLR3 was 4046 bp in length and encoded 895 amino acids. Multiple sequence alignment showed that duck TLR3 shared high similarity with that from other vertebrates.3. Quantitative real-time PCR (qRT-PCR) analysis suggested that TLR3 mRNA was constitutively expressed in all tissues tested, having higher levels in the kidney, liver, breast muscle, ovary and heart. After stimulation with viral- or bacterial-mimics, including LPS, poly(I:C), pam3CSK4, FLS-1, FLA-ST and R848, the TLR3 transcript was significantly upregulated. Meanwhile, overexpression of duck TLR3 significantly promoted the transcription of IFN-β, IRF7, TRIF, Mx, STAT1 and STAT2 mRNA after stimulation with poly(I:C).4. These results suggested that TLR3 play an important role in resistance against viral and bacterial infections in ducks.

Abstract
Abstract
Background
Left ventricular aneurysm (LVA), a serious complication of transmural myocardial infarction, is generally related to poor cardiovascular outcomes. The formation of LVA is essentially an inflammatory remodeling process regulated by multiple systemic and local factors. Epicardial adipose tissue (EAT), a depot of visceral adipose tissue directly overlying the myocardium, is increasingly recognized as an important immune organ by secreting a variety of bioactive adipocytokines. However, the relation of EAT to the development of LVA is still unclear.
Purpose
In this study, we sought to investigate the association between EAT volume and the formation of LVA in subjects with previous myocardial infarction (MI).
Methods
A total of 55 subjects with previous MI and the presence of LVA, and age- and sex-matched 50 subjects with previous MI but without LVA were enrolled between October 2011 and June 2019. EAT was quantified and the presence of LVA was ascertained by cardiac magnetic resonance (CMR). EAT volume was indexed to body surface area.
Results
In the overall population, EAT volume index was correlated positively to log-transformed N-terminal pro-brain natriuretic peptide (NT-proBNP) levels (Pearson's r=0.332, P=0.002), and inversely to left ventricular ejection fraction (LVEF; Pearson's r=−0.240, P=0.031). The indexed EAT volume was significantly higher in subjects with than without LVA (41.10±11.73 vs. 33.25/11.70 mL/m2, P=0.003). In subjects with LVA, EAT volume index was further increased in those at older age (43.59±13.09 mL/m2 vs. 37.29±8.26 mL/m2, P=0.029) or with type 2 diabetes (43.38±12.32 mL/m2 vs. 35.20±7.67 mL/m2, P=0.013). After adjusting for sex, age and the presence of diabetes in the multivariate analysis, tertiles of EAT volume index remained significantly associated with the presence of LVA (P for trend=0. 003). Strikingly, compared to the lowest tertile (≤30.80 mL/m2), the intermediate (30.80–44.13 mL/m2) and highest (>44.13 mL/m2) tertiles of EAT volume index corresponded to 4.869– (95% CI 1.792–14.155, P=0.003) and 4.876– (95% CI, 1.787–14.206, P=0.003) increased risk for LVA.
Conclusion
Our study suggests that EAT volume is independently associated with the formation of LVA and reduced cardiac function after myocardial infarction.

Abstract
Abstract
Background
Chromogranin B (CgB) is a member of granin family that can be cleaved into a number of bioactive peptides. Previous studies showed that CgB is produced in cardiomyocytes and is increased in heart failure animals and patients in proportion to disease severity. Chronic total occlusion (CTO) of coronary artery leads to sustained myocardial ischemia which predisposes to adverse cardiovascular outcomes including heart failure.
Purpose
In this study, we sought to investigate the association between CgB and coronary collateralization formation and heart failure in patients with stable angina and CTO.
Methods
A total of 720 subjects with stable angina and CTO of at least one major coronary artery were enrolled in this study. CgB was assayed using an ELISA kit and the degree of coronary collaterals supplying the distal aspect of a total occlusion from the contralateral vessel was graded according to Rentrop classification.
Results
These was a stepwise decrease in levels of CgB with increasing Rentrop grades of coronary collateralization (P=0.001). Compared with the good collateralization (Rentrop grade 2–3) group, CgB was significantly higher in subjects with poor coronary collateralization (Rentrop grade 0–1; 1222.95 [IQR 506.24–2710.24] pg/mL vs. 776.17 [IQR 276.24–2209.39] pg/mL, P<0.001). Consistent results were found across subgroups of age, sex and the presence of diagnosed diabetes. In subjects with poor collateralization, CgB was positively correlated to N-terminal–pro-brain natriuretic peptide (NT-proBNP) levels (both log-transformed; Pearson's r=0.280, P=0.005). This correlation was markedly enhanced (Pearson's r=0.501, P<0.001) in the poorly-collateralized heart failure subgroup with left-ventricular ejection fraction (LVEF) <50%. Consistently, an inverse correlation was present between log-transformed CgB and LVEF (Pearson's r=−0.528, P<0.001) in the same subgroup. After adjusting for conventional confounding factors and LVEF, CgB remained significantly associated with impaired coronary collateralization (odds ratio: 1.314 [95% CI 1.097–1.590], P=0.004). Inclusion of CgB led to a better diagnostic accuracy as confirmed by net reclassification improvement (NRI) of 17.70% (95% CI 8.08–27.32%, P<0.001) and integrated discrimination improvement (IDI) of 1.98% (95% CI 0.63–3.34%, P=0.004).
Conclusions
CgB is an independent predictor of poor coronary collateralization and is related to worse heart function in patients with stable angina and CTO.

Abstract
Rice blast, caused by Magnaporthe oryzae, is one of the most destructive diseases of rice worldwide. The identification and utilization of resistance genes are crucial and significant for breeding resistant rice cultivars. We identified a resistance gene from Shuangkang77009, which is highly resistant to the rice blast isolate Guy11 using map-based cloning. We performed bulked segregant analysis combined with specific length amplified fragment sequencing. We also performed association analysis, candidate gene prediction and cDNA sequencing to identify the candidate gene. The resistance gene is located on chromosome 6, and we ultimately mapped the resistance locus to a 92-kb region. The resistance gene in Shuangkang77009 was allelic to PigmR, hereafter referred to as Pigm-1. The Pigm-1 protein had one amino acid change: serine (Ser) residue 860 was replaced by tyrosine (Tyr) in Pigm-1 compared with the previously identified Pigm protein, which significantly changed the structure of the Pigm-1 protein based on 3-D structure simulation. In addition, using the developed molecular marker linked to the Pigm-1 gene and molecular marker-assisted selection technology, we introduced the Pigm-1 gene into Minghui86, a widely used and excellent restorer. We generated 11 stable homozygous rice lines with desirable agronomic traits and strong resistance to rice blast. In conclusion, Pigm-1, a natural allelic variant of PigmR, was responsible for blast resistance in Shuangkang77009 rice. The molecular marker-assisted breeding strategy for Pigm-1 was highly efficient.

Abstract
The results of a 3+1 sterile neutrino search using eight years of data from the IceCube Neutrino Observatory are presented. A total of 305 735 muon neutrino events are analyzed in reconstructed energy-zenith space to test for signatures of a matter-enhanced oscillation that would occur given a sterile neutrino state with a mass-squared differences between 0.01 and 100 eV^{2}. The best-fit point is found to be at sin^{2}(2θ_{24})=0.10 and Δm_{41}^{2}=4.5 eV^{2}, which is consistent with the no sterile neutrino hypothesis with a p value of 8.0%.

Abstract
Objective To develop mathematical models for skeletal age determination with multiple statistic method based on the correlation between age and the growth of the epiphysis of extremitas sternalis of clavicle in Shanxi adolescents. Methods The 562 Shanxi sternoclavicular joint samples (454 cases of modelling, 108 cases of external verification) were scanned by the thin-section computed tomography. After volume rendering was obtained, indicators such as area of epiphysis, area of metaphysis, longest diameter of epiphysis and longest diameter of metaphysis of both extremitas sternalis of clavicle were collected. Indicators such as the ratio of area of epiphysis to area of metaphysis, and the ratio of longest diameter of epiphysis to longest diameter of metaphysis of both sides were calculated. Then multiple linear regression and random forest discriminant models were used to build mathematical models for age determination of adolescents. Results The obtained indicators exhibited a strong correlation with age (r>0.85). The multiple linear regression model for males and females (all 4 indicators entering the model) based on the ratio of longest diameter of epiphysis to longest diameter of metaphysis and the ratio of area of epiphysis to area of metaphysis had an internal validation accuracy rate (±1.0 year) of over 92% and 108 cases had an external validation accuracy rate of over 70% (±1.0 year). The out of bag error rates of random forest discriminant models were less than 2% for people over 18.0 years old (≥18.0 years old) and under 18.0 years old. The external validation accuracy rates of the 108 cases were over 80%. Conclusion The regression and discriminant models established in this study have certain reliability and accuracy and can be used in age determination of Shanxi adolescents.

Abstract
OBJECTIVE The aim of this study was to explore the relationship between the mitogen-activated protein kinase (MAPK)/extracellular regulated protein kinase (ERK) pathway and neurocyte apoptosis after cerebral infarction in rats. MATERIALS AND METHODS Neural stem cells were isolated from rats by establishing the cerebral infarction model and sham model. Isolated cells were cultured in complete culture medium in vitro. Real-time quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) was used to detect the messenger ribonucleic acid (mRNA) expression of ERK1 and ERK2 in the MARK pathway. Western blotting was applied to examine the activation of the MAPK/ERK pathway and neuron-specific markers. The expression of neuron-specific enolase (NSE) was detected via immunofluorescence. Cell activity and apoptosis were measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry, respectively. RESULTS The mRNA expressions of ERK1 and ERK2 in neural stem cells increased in a time-dependent manner after cerebral infarction in rats. The expressions of ERK1, ERK2, cyclin D1, Nestin, NSE and glial fibrillary acidic-protein (GFAP) in neural stem cells were significantly decreased after being treated with SCH772984. Cell activity, proliferation and differentiation were markedly inhibited. However, cleaved-caspase 3 protein and apoptosis rate were remarkably increased. CONCLUSIONS The MAPK/ERK pathway seriously affects neurocyte apoptosis after cerebral infarction in rats. When the MAPK/ERK pathway is inhibited, neurocyte apoptosis is remarkably increased after cerebral infarction in rats.

Abstract
We report on the first measurement of the astrophysical neutrino flux using particle showers (cascades) in IceCube data from 2010-2015. Assuming standard oscillations, the astrophysical neutrinos in this dedicated cascade sample are dominated (∼90%) by electron and tau flavors. The flux, observed in the sensitive energy range from 16 TeV to 2.6 PeV, is consistent with a single power-law model as expected from Fermi-type acceleration of high energy particles at astrophysical sources. We find the flux spectral index to be γ=2.53±0.07 and a flux normalization for each neutrino flavor of ϕ_{astro}=1.66_{-0.27}^{+0.25} at E_{0}=100 TeV, in agreement with IceCube's complementary muon neutrino results and with all-neutrino flavor fit results. In the measured energy range we reject spectral indices γ≤2.28 at ≥3σ significance level. Because of high neutrino energy resolution and low atmospheric neutrino backgrounds, this analysis provides the most detailed characterization of the neutrino flux at energies below ∼100 TeV compared to previous IceCube results. Results from fits assuming more complex neutrino flux models suggest a flux softening at high energies and a flux hardening at low energies (p value ≥0.06). The sizable and smooth flux measured below ∼100 TeV remains a puzzle. In order to not violate the isotropic diffuse gamma-ray background as measured by the Fermi Large Area Telescope, it suggests the existence of astrophysical neutrino sources characterized by dense environments which are opaque to gamma rays.

Abstract
Objective: To assess the effectiveness of 1 dose varicella attenuated live vaccine (VarV) for healthy children aged 1-12 years in China and explore the application of the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) framework in observational studies of vaccine effectiveness (VE). Methods: We searched studies about the VE of 1-dose VarV for children aged 1-12 years in China which published before 2019 and evaluated the quality of the studies by the Newcastle Ottawa Scale (NOS) table. We used Meta-analysis models to obtain the pooled 1-dose VE and that in subgroups by study design, outbreak or not, study quality and age of subjects. The evidences of VEs were rated by means of the GRADE system. Results: Thirty-two studies were included and the pooled 1-dose VE was 75% [95% confidence interval (CI): 68%-80%]. The VE of outbreak studies [VE=66% (95%CI: 57%-73%)] was lower than non-outbreak studies [VE=85% (95%CI: 78%-89%)], and the VE in <6 years old children [VE=84% (95%CI:77%-89%)] was higher than that in ≥6 years old children [VE=60% (95%CI: 51%-68%)]. There was no significant difference in VE among studies with different design and quality. The quality of the evidences of pooled 1-dose VE was"very low", which was downgraded in bias risk and inconsistency and not downgraded in indirectness, imprecision and publication bias. Conclusions: The 1-dose VarV can provide medium level protection for 1-12 years old children in China, but it will decrease significantly for ≥6 years old children, so it is suggested to implement the strategies of two-dose vaccination of VarV in children <6 years old. The GRADE framework can be used in the observational studies of VE and it is suggested that the technical guidelines of observational study should be worked out to improve the overall quality of evidence.

Abstract
Objective: To analyze the occurrence and clinical characteristics of testicular adrenal rest tumor (TART) in 21-hydroxylase deficiency (21-OHD) patients, and further explore the possible factors related to the occurrence of TART. Methods: Twenty-seven male 21-OHD patients who visited Peking Union Medical College Hospital from January to December 2018 were enrolled and their clinical and biochemical data were collected. The CYP21A2 mutations were identified by Sanger sequencing and multiple ligation probe amplification (MLPA). Patients were divided into different subgroups according to the residual activity of 21-hydroxylase: Null (residual enzymatic activity 0, 3 cases), group A (0-<1%, 9 cases), group B (1%-5%, 7 cases), group C (20%-50%, 2 cases) and group D (6 cases). The ultrasound of testis was used to detect whether there was TART and its morphological characteristics. Results: Among 27 patients with 21-OHD [average age (17.4±9.3) years], 55.6% (15/27) had TART lesions, most of them were adolescents, and the youngest was only 4 years old. The lesions were mostly bilateral and hypoechoic. The levels of 17α-hydroxyprogesterone (17-OHP) and progesterone in patients with TART were higher than those in patients without TART [17-OHP: 199.6 (62.1, 232.7) nmol/L vs 7.4 (3.2, 105.0) nmol/L, P=0.003; progesterone: 97.1 (42.0, 126.8) nmol/L vs 5.4 (0.7, 20.0) nmol/L, P=0.004]. There was a correlation between the occurrence of TART and genotype of CYP21A2. Patients with Null and A genotypes were more likely to have TART than those with B and C genotypes (8/12 vs 4/9, P=0.021). Conclusions: TART is common in 21-OHD male patients, which is related to 17-OHP and CYP21A2 genotype. It is of great significance for the early screening of TART in 21-OHD patients.

Abstract
Objective: To explore the genetic and environmental effects on alcohol intake. Methods: Data on 9 231 pairs of adult twins of the same sex was collected from the Chinese National Twin Registry (CNTR), between 2015 and 2018 and used in this study. Structural equation model was used to estimate the effects of genetic and environmental factors on alcohol intake. Results: A total of 9 231 pairs of twins were included in the analysis, of which 6 085 pairs were monozygotic (MZ). The average age of MZ was (36.91±13.07) years old, and males accounted for 56.80%. The average age of dizygotic twins (DZ) was (35.22±12.48) years old, and males accounted for 55.91%. There were 350 pairs of alcohol-drinking twins were with high-risk, accounting for 1.90% and another 367 pairs (1.99%) were with medium-risk. Alcohol-drinkers with medium-risk were affected by additive genetics, common and unique environmental factors, seen among the twins. The overall heritability appeared as 24.3% (95%CI: 0 to 56.8%). Furthermore, 50.7% of the variation (95%CI: 20.4%-79.0%) could be explained by the common environmental factors and 24.9% (95%CI: 18.3%-36.5%) by unique environmental factors. High-risk related drinking behavior was affected by both common and unique environmental factors. The common environmental component appeared as 75.6% (95%CI: 69.6%-80.8%) and unique environmental component as 24.4% (95%CI: 19.2%-30.4%), respectively. Gender difference was seen in the heritability of those with medium or high-risk drinking behaviors. The heritability of men was 30.8% (95%CI: 9.8%-53.5%), while in women it was mainly affected by the environment. Conclusion: Both alcohol drinkers with medium and high-risk drinking behaviors were mainly affected by the environment factors and gender. With the increase of drinking volume, the effect of environment on drinking behaviors became more obvious.

Abstract
Background:Fibroblast heterogeneity and homeostasis has long been recognized in patients with systemic sclerosis (SSc). However, there is no common consensus on fibroblast subtypes, lineages, biological properties, signaling, and plasticity, which severely hampers our understanding of SSc pathogenesis.Objectives:This study is aimed to comprehensively classify skin fibroblast populations from SSc patients.Methods:We applied single-cell RNA sequencing on skin fibroblasts from two SSc patients and two health control (HC) with matched age and sex. Cell clustering were mainly determined by UMAP with batch effect correction. Differently expressed genes in each cell cluster was analyzed by Gene Set Enrichment Analysis (GSEA).Results:With an unbiased approach, single-cell transcriptome analyses showed classified and defined eight fibroblast types in SSc skin and six in normal skin. The cell types seldom overlapped between the patients and HC. Extracellular interaction and collagen production were remarkably stronger in SSc fibroblasts. A subgroup of dramatic cell proliferation and activation was defined only in SSc fibroblast. Two subtypes responding inflammatory stimuli were only found in SSc patients. Furthermore, delineation of their differentiation trajectory was achieved by a machine learning method.Conclusion:This collection of single-cell transcriptomes and the distinct classification of fibroblast subsets provide a new resource for understanding the fibroblast landscape and the roles of fibroblasts in SSc.References:N/ADisclosure of Interests:None declared
