Abstract
Objective: To investigate the changes of the microstructure and vascular density in the superficial retinal layer of buried optic disc drusen (ODD) patients. Methods: Retrospective case-control study. A total of 36 ODD eyes (20 patients) and 26 normal control eyes were recruited in Beijing Union Medical College Hospital from January 2018 to July 2020. Measurement of best corrected visual acuity (BCVA), intraocular pressure, slit lamp, fundus examination and visual field examination were performed. The images and data of spectral domain-optical coherence tomography (SD-OCT) and optical coherence tomography angiography (OCTA) were analyzed and summarized. The differences of nasal retinal nerve fiber layer (RNFL), ganglion cell complex (GCC) thickness and macular superficial vascular density (VD) between ODD patients and normal controls were compared by independent sample t-test or Mann Whitney U test (the right eye was selected in bilateral ODD patients). Results: The 20 ODD patients and 26 normal controls were all female. There was no significant difference in age between the two groups (P>0.05). The BCVA and visual field examination was normal in all ODD patients. The SD-OCT examination showed an oval low signal shadow under the nasal outer nuclear layer of the optic disc, or local accumulation like a medium signal shadow with a clear boundary, and a high signal capsule in ODD patients. The RNFL in the upper nasal side of the ODD group was significantly different from the normal control group [(102.6±19.1) μm vs. (119.0±13.8) μm; t=-2.81; P<0.01]. Compared with normal control group [101.0 (100.0, 102.0) μm], the average GCC thickness in the ODD group [97.0 (89.3, 99.8) μm] was significantly different (U=48.50; P<0.01). The OCTA en-face scan showed that the vascular network in the macular area of the affected eyes was sparser than that of the control eyes. There was significant difference in superficial macular VD beteeen the ODD group (48.5%±2.8%) and the control group (51.0%±2.3%) (t=-2.63; P<0.05). Conclusions: There is thinning in the RNFL upper nasal side and GCC layer of the macular region in buried ODD patients, and the superficial VD of the macular region in buried ODD patients is lower than that in the normal controls.

Abstract
Multiple sclerosis (MS) is an inflammatory reactive autoimmune disease characterized by diffuse axonal degeneration of the central nervous system. The exact etiology and pathogenesis remain unclear. Optical coherence tomography angiography is a new technology of angiography, which can obtain the images of each layer of blood vessels in the scanning area. It is non-invasive, fast and quantifiable. Observation of retinal vasculopathy may assist in the evaluation of brain diseases. This article reviews the previous research results at home and abroad of ocular blood flow changes observed by optical coherence tomography angiography in MS in recent years, in order to provide reference for the study of the underlying pathogenesis of MS and clinical evaluation.

Abstract
With the motivation to study how non-magnetic ion site disorder affects the quantum magnetism of Ba3CoSb2O9, a spin-1/2 equilateral triangular lattice antiferromagnet, we performed DC and AC susceptibility, specific heat, elastic and inelastic neutron scattering measurements on single crystalline samples of Ba2.87Sr0.13CoSb2O9with Sr doping on non-magnetic Ba2+ion sites. The results show that Ba2.87Sr0.13CoSb2O9exhibits (i) a two-step magnetic transition at 2.7 K and 3.3 K, respectively; (ii) a possible canted 120 degree spin structure at zero field with reduced ordered moment as 1.24μB/Co; (iii) a series of spin state transitions for bothH∥ab-plane andH∥c-axis. ForH∥ab-plane, the magnetization plateau feature related to the up-up-down phase is significantly suppressed; (iv) an inelastic neutron scattering spectrum with only one gapped mode at zero field, which splits to one gapless and one gapped mode at 9 T. All these features are distinctly different from those observed for the parent compound Ba3CoSb2O9, which demonstrates that the non-magnetic ion site disorder (the Sr doping) plays a complex role on the magnetic properties beyond the conventionally expected randomization of the exchange interactions. We propose the additional effects including the enhancement of quantum spin fluctuations and introduction of a possible spatial anisotropy through the local structural distortions.

Abstract
Objective: To analyze the clinical phenotype and screen the genetic mutations of hereditary deafness in three deaf families to clarify their molecular biology etiology. Methods: From January 2019 to January 2020, three deaf children and family members were collected for medical history, physical examination, audiology evaluation, electrocardiogram and cardiac color Doppler ultrasound, temporal bone CT examination, and peripheral blood DNA was obtained for high-throughput sequencing of deafness genes. Sanger sequencing was performed to verify the variant sites among family members. The pathogenicity of the variants was evaluated according to the American College of Medical Genetics and Genomics. Results: The probands in the three families had deafness phenotypes. In family 1, proband had multiple lentigines, special facial features, growth retardation, pectus carinatum, abnormal skin elasticity, cryptorchidism and other manifestations. In family 2, proband had special facial features, growth retardation and abnormal heart, and the proband in family 3 had growth retardation and abnormal electrocardiogram. Genetic testing of three families detected three heterozygous mutations in the PTPN11 gene: c.1391G>C (p.Gly464Ala), c.1510A>G (p.Met504Val), c.1502G>A (p.Arg501Lys). All three sites were missense mutations, and the mutation sites were highly conserved among multiple homologous species. Based on clinical manifestations and genetic test results, proband 1 was diagnosed with multiple lentigines Noonan syndrome, and probands 2 and 3 were diagnosed with Noonan syndrome. Conclusion: Missense mutations in the PTPN11 gene may be the cause of the disease in the three deaf families. This study enriches the clinical phenotype and mutation spectrum of the PTPN11 gene in the Chinese population.

Abstract
Objective: To analyze the trend of child and adolescent mortality rate in China from 2004 to 2018 and explore the possible policy effects. Methods: This study used the mortality data of child and adolescent aged 5 to 19 years from 2004 to 2018 based on the National Disease Surveillance System. Age-standardized mortality rate was calculated by using the population from the sixth national census. Joinpoint regression was used to analyze the trend of child and adolescent mortality with different features from 2004 to 2018. Results: From 2004 to 2018, the overall mortality rate of children and adolescents in China dropped from 40.02 per 100 000 to 22.00 per 100 000, and the average annual percentage change (AAPC) was -4.28 (95%CI:-5.35,-3.20,P<0.001). The mortality rate dropped rapidly from 2004 to 2006, and the annual percentage change (APC) was -9.20 (95%CI:-15.63,-2.28,P=0.017). The decline rate slowed down between 2006 and 2013, and the APC was -1.56 (95%CI:-2.78,-0.33,P=0.020). The downward trend accelerated from 2013 to 2018, and the APC was -5.99 (95%CI:-7.52,-4.43,P<0.001). The trend of child mortality rate in rural area, females, eastern provinces of China, children aged 10 to 14 years, children aged 15 to 19 years, and injury mortality rate were basically consistent with the overall trend. The child mortality rate in urban area, central provinces of China and the mortality rate of infectious diseases, maternal and infant, and nutritional deficiencies diseases showed a uniform downward trend from 2004 to 2018, with AAPC values about -3.59 (95%CI:-4.38,-2.78,P<0.001), -2.89 (95%CI:-3.24,-2.54,P<0.001) and -6.66 (95%CI:-7.64,-5.68,P<0.001), respectively. Conclusion: The mortality rate of children and adolescents aged 5 to 19 years in China continues to decline from 2004 to 2018, and the decline rate becomes faster after 2011.

Abstract
Objective: To compare clinical and laboratory features between JAK2 exon12 and JAK2 V617F mutated polycythemia vera (PV) . Method: We collected data from 570 consecutive newly-diagnosed subjects with PV and JAK2 mutation, and compared clinical and laboratory features between patients with JAK2 exon12 and JAK2 V617F mutation. Results: 543 (95.3%) subjects harboured JAK2 V617F mutation (JAK2 V617F cohort) , 24 (4.2%) harboured JAK2 exon12 mutations (JAK2 exon12 cohort) , and 3 (0.5%) harboured JAK2 exon12 and JAK2 V617F mutations. The mutations in JAK2 exon12 including deletion (n=10, 37.0%) , deletion accompanied insertion (n=10, 37.0%) , and missense mutations (n=7, 25.9%) . Comparing with JAK2 V617F cohort, subjects in JAK2 exon12 cohort were younger [median age 50 (20-73) years versus 59 (25-91) years, P=0.040], had higher RBC counts [8.19 (5.88-10.94) ×10(12)/L versus 7.14 (4.11-10.64) ×10(12)/L, P<0.001] and hematocrit [64.1% (53.7-79.0%) versus 59.6% (47.2%-77.1%) , P=0.001], but lower WBC counts [8.29 (3.2-18.99) ×10(9)/L versus 12.91 (3.24-38.3) ×10(9)/L, P<0.001], platelet counts [313 (83-1433) ×10(9)/L versus 470 (61-2169) ×10(9)/L, P<0.001] and epoetin [0.70 (0.06-3.27) versus 1.14 (0.01-10.16) IU/L, P=0.002] levels. We reviewed bone marrow histology at diagnosis in 20 subjects with each type of mutation matched for age and sex. Subjects with JAK2 exon12 mutations had fewer loose megakaryocyte cluster (40% versus 80%, P=0.022) compared with subjects with JAK2 V617F. The median follow-ups were 30 months (range 4-83) and 37 months (range 1-84) for cohorts with JAK2 V617F and JAK2 exon12, respectively. There was no difference in overall survival (P=0.422) and thrombosis-free survival (P=0.900) . Conclusions: Compared with patients with JAK2 V617F mutation, patients with JAK2 exon12 mutation were younger, and had more obvious erythrocytosis and less loose cluster of megakaryocytes.

Abstract
Objective: To analyze the effects of unsafe sexual behavior and sexual orientation on previous HIV testing and HIV testing willingness among college students in Harbin, to provide a theoretical basis for promoting and promoting HIV testing among them. Methods: A cross-sectional survey design was used to place the automatic vending machine of HIV urine test kit in 9 universities in Harbin from December 2017 to January 2018. The questionnaire star was used to design and recruit college students to carry out an anonymous online survey. The estimated sample size was 6 659. A multivariate logistic regression model was used to analyze the effects of unsafe sexual behavior and sexual orientation on previous HIV testing and HIV testing willingness among college students. WPS 2016 was used to sort out the database, and SPSS 21.0 software was used for statistical analysis. Results: A total of 60 849 valid questionnaires were collected. 19.1% (11 189/58 605) of college students reported having sex. College students who used condoms correctly every time, occasionally or never during sex in the past six months 58.5% (6 206/10 603), 25.2%(2 669/10 603)and 16.3% (1 728/10 603), respectively. Heterosexuality, homosexuality and bisexuality accounted for 94.1% (54 393/57 823), 2.4% (1 369/57 823) and 3.5% (2 061/57 823), respectively. The HIV testing willingness of college students was 73.3% (44 572/60 849). The proportion of previous HIV testing was 10.3% (951/9 241). Results of the multivariate logistic analysis showed that compared with the college students who used condoms correctly whenever they had sex in the past six months, there was no significant difference in the proportion of previous HIV testing among college students who sometimes/occasionally used or never used condoms (OR=0.94,95%CI:0.69-1.29; OR=1.11,95%CI:0.73-1.67), but their willingness to HIV testing was lower (OR=0.79, 95%CI:0.71-0.89; OR=0.48, 95%CI:0.42-0.55); Compared with heterosexual college students, homosexual or bisexual college students have a higher proportion of previous HIV testing (OR=2.62, 95%CI:1.62-4.24; OR=2.04, 95%CI:1.25-3.32), but have lower HIV testing willingness (OR=0.76, 95%CI: 0.62-0.93; OR=0.64, 95%CI: 0.53-0.77). Conclusions: Unsafe sexual behavior existed among college students in Harbin, and college students with weak awareness of HIV prevention also have weak awareness of testing. Behavioral intervention should be strengthened and HIV testing promoted. Compared with heterosexuals, homosexual or bisexual college students had a higher proportion of previous HIV testing, but their willingness to test was lower. The HIV detection mode with better concealment, accuracy, and convenience should be promoted on the college's campus.

Abstract
OBJECTIVES We aimed to evaluate the association between sleep duration and obesity and estimate the attributable risk of sleep in the China Health and Retirement Longitudinal Study surveys (CHARLS). METHODS A total of 9061 adults aged 45 years above from CHARLS (2011-2015) were included. The main outcome of this study was incident overweight/obesity specific to general and abdominal obesity. Overweight/obesity was defined as BMI ≥ 23.0 (kg/m2) and BMI≥27.5 (kg/m2), respectively. Abdominal obesity was defined as waist circumference ≥90 cm for men and ≥80 cm for women. Self-reported sleep durations were obtained using a structured questionnaire. We assessed hazard ratios (HRs) and 95% confidence intervals (CIs) as well as the population attributable fraction (PAF) for associations between sleep duration and obesity. RESULTS 986 and 606 participants were identified as overweight and general obesity respectively, 1253 experienced abdominal obesity events. In multivariable-adjusted models, participants with daytime sleep of 0-30 minutes and more than 30 minutes associated with 30% (HR: 0.70, 95% CI: 0.56-0.87) and 35% (HR: 0.65, 95% CI: 0.55-0.78) decreased incident overweight risk respectively compared to those having no daytime sleep, this association also found among females and middle-aged, not males or elderly. Similarly, 0-30 minutes (HR: 0.68, 95% CI: 0.48-0.96) and more than 30 minutes of daytime sleep (HR: 0.73, 95% CI: 0.59-0.91) were associated with a reduced risk of abdominal obesity, similar results also found among females and middle-aged. Compared with 7-9 hours of nocturnal sleep, people who slept 5-7 hours had a reduced risk of overweight (HR: 0.59, 95% CI=0.47-0.74),but not found in subgroups. The hazard role of long nocturnal sleep for abdominal obesity was only found among elderly (HR: 2.33, 95% CI=1.35-4.04) and males (HR: 2.24, 95% CI=1.17-4.29). Compared with moderate total sleepers (7-9hours/day), participants with short total sleep duration exhibited an elevated risk of overweight (HR: 1.13, 95% CI=1.00-1.28), this also found among middle-aged. The PAF for inadequate total sleep duration (<7 hours/day) was 10.77% for overweight individuals. CONCLUSIONS Insufficient sleep duration was associated with an elevated risk of overweight only detected among middle-aged not elderly and other subgroups specific by age. The risks for abdominal obesity were increased for males and middle-aged with long nocturnal sleep. Daytime sleep may significantly reduce the risk of overweight and abdominal obesity in female and middle-aged individuals. The link between sleep duration and obesity requires further study.

Abstract
BACKGROUND Dysfunction of airway epithelial cells in patients with asthma is closely with the occurrence and development of allergic asthma. Finding the differences of airway epithelium between asthmatic patients and normal patients is helpful to find out new treatment strategies. METHODS First, three original microarray datasets (GSE89809, GSE41861, GSE104468) from the Gene Expression Omnibus (GEO) dataset were used to assess differentially expressed genes in the epithelial tissues between patients with allergic asthma and healthy controls. Then, 10 ng/mL TGF-β1 treated BEAS-2B cells and rats with ovalbumin induced allergic asthma were performed to confirm our assumption from the gene expression analysis with microarrays. RESULTS Top ten hub significant difference genes were obtained by Cytohubba plug-in from GSE41861, and found that androgen receptor (AR) was closely associated with the mitogen-activated protein kinase (MAPK) pathway, especially MAPK1 and MAPK14. After treated with the TGF-β1 treated BEAS-2B cells and rats with allergic asthma, we found that 5α-dihydrotestosterone (5α-DHT), AR agonist, significantly decreased the Th2 inflammation (IL-25 and IL-33), MAPK1 and MAPK14 proteins expression in vitro and in vivo. The roles of 5α-DHT were similar with the results of chicanine (a p38 MAPK and ERK1/2 inhibitor), but the roles of 5α-DHT were masked by the C16-PAF (a MAPK and MEK/ERK activator) treatment. CONCLUSION Androgen receptor limits the secretion of Th2 inflammatory factors by downregulating MAPK1 and MAPK14 in the TGF-β1 treated BEAS-2B cells and rats with ovalbumin induced allergic asthma, which plays a critical role for the therapeutics of patients with asthma.

Abstract
A questionnaire was used to investigate the emergency training needs of novel coronavirus pneumonia of disease prevention and control institutions in provinces, deputy provincial level regions and cities specifically designated in the state plan, and the effect evaluation of emergency training activities conducted by Chinese Center for Disease Control and Prevention (China CDC). The results showed that 67.4% of 47 disease prevention and control institutions (31/46) believed that the emergency training at the initial stage of the epidemic should be conducted as soon as possible, and the form of network training should be given priority. The training should focus on the urgently needed technologies such as epidemiological investigation, formulation and response of prevention and control strategies, laboratory testing, etc. The teaching materials should highlight pertinence and practicability and be presented in the form of electronic video. The average satisfaction score of the video training conducted by China CDC was (8.81±1.125) and the score of audio-video courseware was (8.97±0.893). The needs analysis and evaluation of novel coronavirus pneumonia prevention and control in disease prevention and control institutions could provide reference for the follow-up training and improve the emergency training management.

Abstract
miRNAs are a class of hairpin‐derived RNAs, 21–24 nucleotides in length, which are involved in a range of biological processes. The bta‐miR‐2285 family has over 40 members spanning the entire bovine genome. We previously found that bta‐miR‐2285o‐3p was highly expressed in yak heart and lung when compared with cattle, which prompted us to investigate its potential function in high‐altitude adaptation of yaks. In this study, we detected wide‐spread high expression of bta‐miR‐2285o‐3p in yak tissues. Further experiments revealed that the protein tyrosine phosphatase receptor type M (PTPRM) gene was the host gene of bta‐miR‐2285o‐3p and that two linked SNPs in bta‐mir‐2285o precursor affected the biogenesis of mature miRNA (bta‐miR‐2285o‐3p). Functional analysis in vitro indicated that bta‐miR‐2285o‐3p attenuated hypoxia‐induced apoptosis by targeting very low‐density lipoprotein receptor (VLDLR), phosphatase and tensin homolog (PTEN) and caspase‐3. Expression level analysis in vivo revealed the high negative Pearson’s correlation between bta‐miR‐2285o‐3p and caspase3 in yak, highlighting the potential important roles of bta‐miR‐2285o‐3p in yak high‐altitude adaptation. Our study provides a typical model for deciphering the function of miRNAs in environmental adaptation.
