Abstract
Patients diagnosed with inflammatory bowel disease or related conditions also frequently suffer from osteoporosis as a consequence of changes in the intestinal microenvironment and consequent dysbiosis. We hypothesized that anti-inflammatory probiotic treatment would be sufficient to alleviate intestinal inflammation and thereby prevent the development of osteoporosis. To that end, the ability of Bifidobacterium lactis BL-99 administration to protect against bone loss in an experimental model of dextran sodium sulfate-induced ulcerative colitis (UC) was analyzed, and the underlying molecular mechanisms were interrogated in detail. The results of these analyses revealed that BL-99 administration suppressed colitis-associated weight loss (P < 0.05), disease activity index scores, and the production of proinflammatory cytokines (TNF-α, IL-1β, IL-6, and IL-17) (P < 0.05). Colon tissue pathological sections similarly revealed BL-99-mediated reductions in tissue injury severity. Micro-computed tomography (Micro-CT) analyses further exhibited significant improvements in percent bone volume (BV/TV) as well as trabecular number and thickness in BL-99-treated animals (P < 0.05). Such probiotic supplementation also resulted in pronounced changes in the composition of the gut microbiota. Moreover, BL-99 intervention markedly increased the expression of intestinal barrier-related proteins (Claudin-1, MUC2, ZO-1, and Occludin). Together, these results suggest that BL-99 can be utilized as a beneficial probiotic preparation to prevent the incidence of osteoporosis in UC patients owing to its ability to shape the intestinal microflora and to suppress inflammatory cytokine production.

Abstract
Severe Coronavirus Disease 2019 (COVID-19) is characterized by numerous complications, complex disease, and high mortality, making its treatment a top priority in the treatment of COVID-19. Integrated traditional Chinese medicine (TCM) and western medicine played an important role in the prevention, treatment, and rehabilitation of COVID-19 during the epidemic. However, currently there are no evidence-based guidelines for the integrated treatment of severe COVID-19 with TCM and western medicine. Therefore, it is important to develop an evidence-based guideline on the treatment of severe COVID-19 with integrated TCM and western medicine, in order to provide clinical guidance and decision basis for healthcare professionals, public health personnel, and scientific researchers involved in the diagnosis, treatment, and care of COVID-19 patients. We developed and completed the guideline by referring to the standardization process of the "WHO handbook for guideline development", the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, and the Reporting Items for Practice Guidelines in Healthcare (RIGHT).

Abstract
1. A better understanding of intestinal development is essential for the intestinal health of poultry. Intestinal villification starts on embryo day E15 and is generally completed before hatching (E21). The development of lymphoid organs in the intestine starts during embryogenesis. However, transcriptional information on the processing of intestinal morphogenesis and immune development during chick embryogenesis is limited.2. In this work, RNA-sequencing was performed using 12 biological replicates to investigate Hy-Line brown chick embryonic small intestinal transcription at E15 and E21. Differentially expressed genes (DEGs) between E15 and E21 were identified. GO and KEGG enrichment analyses, based on the DEGs, were performed to identify key GO terms in the biological process category and key KEGG pathways. PPI networks were constructed based on the DEGs in the key pathways to screen hub genes. The embryonic small intestinal morphology and IgA distribution were observed by histological processing. The serum levels of IgA and lysozyme were measured by ELISA.3. A total of 76.38 Gb of high-quality RNA-sequencing data were generated and uploaded. A total of 2,676 DEGs, between E15 and E21, were identified. Structural development and villification of the small intestine at E15 tended to proceed via the expression of nervous system development-related genes. A combination of the histological and serological results with the transcriptome data indicated that the identified genes and pathways may be strong candidates for intestinal morphogenesis-regulation.4. The small intestine appears to have developed a relatively complete morphology and transport, metabolism, digestion and immunity functions by E21. This work provided a transcriptome profile of the chick embryonic small intestine and provided insights into the intestinal development and health of poultry.

Abstract
Background Hundreds of coronavirus disease 2019 (COVID-19) clinical practice guidelines (CPGs) and expert consensus statements have been developed and published since the outbreak of the epidemic. However, these CPGs are of widely variable quality. So, this review is aimed at systematically evaluating the methodological and reporting qualities of COVID-19 CPGs, exploring factors that may influence their quality, and analyzing the change of recommendations in CPGs with evidence published. Methods We searched five electronic databases and five websites from 1 January to 31 December 2020 to retrieve all COVID-19 CPGs. The assessment of the methodological and reporting qualities of CPGs was performed using the AGREE II instrument and RIGHT checklist. Recommendations and evidence used to make recommendations in the CPGs regarding some treatments for COVID-19 (remdesivir, glucocorticoids, hydroxychloroquine/chloroquine, interferon, and lopinavir-ritonavir) were also systematically assessed. And the statistical inference was performed to identify factors associated with the quality of CPGs. Results We included a total of 92 COVID-19 CPGs developed by 19 countries. Overall, the RIGHT checklist reporting rate of COVID-19 CPGs was 33.0%, and the AGREE II domain score was 30.4%. The overall methodological and reporting qualities of COVID-19 CPGs gradually improved during the year 2020. Factors associated with high methodological and reporting qualities included the evidence-based development process, management of conflicts of interest, and use of established rating systems to assess the quality of evidence and strength of recommendations. The recommendations of only seven (7.6%) CPGs were informed by a systematic review of evidence, and these seven CPGs have relatively high methodological and reporting qualities, in which six of them fully meet the Institute of Medicine (IOM) criteria of guidelines. Besides, a rapid advice CPG developed by the World Health Organization (WHO) of the seven CPGs got the highest overall scores in methodological (72.8%) and reporting qualities (83.8%). Many CPGs covered the same clinical questions (it refers to the clinical questions on the effectiveness of treatments of remdesivir, glucocorticoids, hydroxychloroquine/chloroquine, interferon, and lopinavir-ritonavir in COVID-19 patients) and were published by different countries or organizations. Although randomized controlled trials and systematic reviews on the effectiveness of treatments of remdesivir, glucocorticoids, hydroxychloroquine/chloroquine, interferon, and lopinavir-ritonavir for patients with COVID-19 have been published, the recommendations on those treatments still varied greatly across COVID-19 CPGs published in different countries or regions, which may suggest that the CPGs do not make sufficient use of the latest evidence. Conclusions Both the methodological and reporting qualities of COVID-19 CPGs increased over time, but there is still room for further improvement. The lack of effective use of available evidence and management of conflicts of interest were the main reasons for the low quality of the CPGs. The use of formal rating systems for the quality of evidence and strength of recommendations may help to improve the quality of CPGs in the context of the COVID-19 pandemic. During the pandemic, we suggest developing a living guideline of which recommendations are supported by a systematic review for it can facilitate the timely translation of the latest research findings to clinical practice. We also suggest that CPG developers should register the guidelines in a registration platform at the beginning for it can reduce duplication development of guidelines on the same clinical question, increase the transparency of the development process, and promote cooperation among guideline developers all over the world. Since the International Practice Guideline Registry Platform has been created, developers could register guidelines prospectively and internationally on this platform.

Abstract
Light perception at dawn plays a key role in coordinating multiple molecular processes and in entraining the plant circadian clock. The Arabidopsis mutant lacking the main photoreceptors, however, still shows clock entrainment, indicating that the integration of light into the morning transcriptome is not well understood. In this study, we performed a high-resolution RNA-sequencing time-series experiment, sampling every 2 min beginning at dawn. In parallel experiments, we perturbed temperature, the circadian clock, photoreceptor signaling, and chloroplast-derived light signaling. We used these data to infer a gene network that describes the gene expression dynamics after light stimulus in the morning, and then validated key edges. By sampling time points at high density, we are able to identify three light- and temperature-sensitive bursts of transcription factor activity, one of which lasts for only about 8 min. Phytochrome and cryptochrome mutants cause a delay in the transcriptional bursts at dawn, and completely remove a burst of expression in key photomorphogenesis genes (HY5 and BBX family). Our complete network is available online (http://www-users.york.ac.uk/∼de656/dawnBurst/dawnBurst.html). Taken together, our results show that phytochrome and cryptochrome signaling is required for fine-tuning the dawn transcriptional response to light, but separate pathways can robustly activate much of the program in their absence.

Abstract
Pregnancy zone protein (PZP), a member of the proteinase inhibitor I39 (‐2‐macroglobulin) family of proteins, is involved in the initiation and development of various tumors. The gene encoding PZP is hypermethylated and expressed at low levels in hepatocellular carcinoma (HCC) tissue and cells, but the function of PZP in HCC cells remains unclear. Here, we analyzed DNA methylation and mRNA expression of HCC in The Cancer Genome Atlas Liver Hepatocellular Carcinoma dataset. We identified 10 methylation‐driven genes, of which PZP was significantly hypermethylated and poorly expressed in tumor tissue. We confirmed that PZP is highly methylated and poorly expressed in HCC cell lines via quantitative real‐time PCR experiment and methylation‐specific PCR. Furthermore, PZP markedly inhibited the proliferation, invasion and migration of HCC cells. These findings may provide a basis for exploring novel therapeutic targets for HCC.

Abstract
Abstract
Aims
Short QT syndrome (SQTS), a disorder associated with characteristic electrocardiogram QT-segment abbreviation, predisposes afflicted patients to sudden cardiac death. Despite some progress in assessing the organ level pathophysiology and genetic changes of the disorder, the understanding of the human cellular phenotype and discovering of an optimal therapy has lagged due to a lack of appropriate human cellular models of the disorder. The aim of this study was to establish a cellular model of SQTS type 5 using human-induced pluripotent stem cell–derived cardiomyocytes (hiPSC-CMs) and gene-edited cell line using CRISPR/CAS9.
Methods and results
This study recruited one patient with short QT syndrome type 5 carrying a mutation in CACNb2 gene as well as one healthy control subject. We generated hiPSCs from their skin fibroblasts, and differentiated hiPSCs into cardiomyocytes (hiPSC-CMs) for physiological. Isogenic control hiPSC-CMs generated by the CRISPR/CAS9 technique were also used for the study.
The hiPSC-CMs from the patient showed a reduced calcium current (ICa-L) density and shortened action potential duration (APD) compared with healthy control hiPSC-CMs and isogenic hiPSC-CMs. Furthermore, they demonstrated abnormal rhythmic activities. Carbachol increased the arrhythmic events in SQTS significantly but not in healthy and isogenic control cells. Gene and protein expression profiling showed a decreased CACNb2 expression in SQTS cells. Quinidine prolonged the APD and abolished arrhythmic activity.
Conclusions
Patient-specific hiPSC-CMs are able to recapitulate single-cell phenotype features of SQTS type 5 and provide novel opportunities to further elucidate the cellular disease mechanism and test drug effects.

Abstract
OBJECTIVE To investigate the association of gr/gr, b2/b3 and gr/gr with b1-2/b3-4 deletions (repetitions) in the AZFc region of the Y chromosome with recurrent spontaneous abortion (RSA). METHODS Using the next-generation sequencing technology, we examined the men with indications of Y chromosome microdeletion at our center from June 2017 to March 2018 and excluded the common causes of RSA through inquiry and other related examinations. Totally, 170 cases of AZFc deletion (80 cases of gr/gr deletion, 75 cases of b2/b3 deletion, and 15 cases of gr/gr with b1-2/b3-4 deletion) were detected and included in the case group, and another 328 normal males enlisted as controls. We analyzed the correlation of Y chromosome microdeletions with the incidence rate of RSA. RESULTS The incidence rate of RSA was significantly higher in the case group than in the normal controls (28.8% [49/170] vs 13.1% [43/328], P < 0.01), 22.5% (18/80) in the gr/gr deletion cases (P < 0.05), 30.7% (23/75) in the b2/b3 deletion cases (P < 0.01), and 53.3% (8/15) in the gr/gr with b1-2/b3-4 deletion cases (P < 0.01), remarkably lower in the gr/gr than in the gr/gr with b1-2/b3-4 deletion subgroup (P < 0.05), but with no statistically significant difference between the other subgroups. CONCLUSIONS The gr/gr, b2/b3, and gr/gr with b1-2/b3-4 deletions (repetitions) in the AZFc region of the Y chromosome may cause recurrent spontaneous abortion.

Abstract
This paper presents a method of using femtosecond laser inscribed nanograting as low-loss- and high-temperature-stable in-fiber reflectors. By introducing a pair of nanograting inside the core of a single-mode optical fiber, an intrinsic Fabry-Perot interferometer can be created for high-temperature sensing applications. The morphology of the nanograting inscribed in fiber cores was engineered by tuning the fabrication conditions to achieve a high fringe visibility of 0.49 and low insertion loss of 0.002 dB per sensor. Using a white light interferometry demodulation algorithm, we demonstrate the temperature sensitivity, cross-talk, and spatial multiplexability of sensor arrays. Both the sensor performance and stability were studied from room temperature to 1000°C with cyclic heating and cooling. Our results demonstrate a femtosecond direct laser writing technique capable of producing highly multiplexable in-fiber intrinsic Fabry-Perot interferometer sensor devices with high fringe contrast, high sensitivity, and low-loss for application in harsh environmental conditions.

Abstract
Objective: To explore the correlation between dietary N-glycolylneuraminic acid (Neu5Gc) intake and chronic inflammation state of body. Methods: A total of 306 samples of 102 types of food were purchased from a supermarket in Xiamen in September 2019, including grains, meat, poultry, seafood, eggs, beans, dairy products, vegetables and fruits. The content of Neu5Gc in food was determined by liquid chromatography-mass spectrometry. A total of 500 healthy freshmen from Xiamen University were selected by using a simple random sampling method. The food frequency questionnaire was used to investigate the food intake in the past year. The food intake was corrected by 3 consecutive 24-hour recalls, and the amount of Neu5Gc intake was calculated. The concentration of anti-Neu5Gc antibody, C-reactive protein (CRP) and interleukin-6 (IL-6) in serum was detected. Spearman correlation analysis was used to explore the correlation between Neu5Gc intake and anti-Neu5Gc antibody, CRP and IL-6 levels. Results: Neu5Gc was mainly found in red meat and liquid dairy products. The contents of Neu5Gc in beef, lamb and pork were (30.32±2.84), (20.39±4.73) and (5.58±1.04) mg/kg, respectively, and in liquid milk and yogurt were (10.87±1.54) and (6.91±0.24) mg/L, respectively. The M (P25, P75) intake of Neu5Gc for all participants was 4.62 (2.20, 8.60) mg/d. The M(P25, P75) intake of Neu5Gc for males about 6.60(2.83, 10.20) was higher than that for females about [3.84 (1.84, 6.35) mg/d] (P<0.001). The M (P25, P75) of serum anti-Neu5Gc, CRP and IL-6 levels were 3.07 (2.17, 4.14) μg/ml, 0.37 (0.22, 0.87) mg/ml and 61.82 (12.23, 315.30) pg/ml, respectively. Spearman correlation analysis showed that the intake level of Neu5Gc was positively correlated with serum anti-Neu5Gc antibody, CRP and IL-6 levels, with rs values about 0.222, 0.102 and 0.126, respectively (all P values <0.05). Conclusion: Dietary Neu5Gc intake is mainly from red meat and liquid dairy products, and its intake level is positively correlated with chronic inflammatory state of body.

Abstract
In order to achieve long-pulse H-mode plasma scenario over 400 s with high heating power in the Experimental Advanced Superconducting Tokamak (EAST) device, the lower graphite divertor will be upgraded into a tungsten (W) divertor with active water cooling, which consists of the W/Cu monoblock units and the W flat-tile units as the divertor plasma facing components. As a fundamental diagnostic tool, the divertor Langmuir probe (Div-LP) diagnostic system will be upgraded accordingly. This paper presents the design of two kinds of new Div-LP systems, which are planned to be utilized on the W/Cu monoblock units and the W flat-tile units for the upgraded lower tungsten divertor, respectively, including their structures and preliminary poloidal and toroidal layouts. The Div-LP diagnostic system can measure the plasma parameters with the schemes of triple-probe, double-probe, and single-probe, to obtain the spatial and temporal distribution of plasma behavior on the divertor targets, which is useful for the discharge control and operation in EAST. In addition, the thermal analysis of the two kinds of probe assemblies is also carried out by using the three-dimensional finite element code ANSYS, which is aimed to get the optimal designs to withstand the long-pulse and high-power operation in EAST future experiments.

Abstract
Objective: To explore the characteristics and methods of different fixation methods and prevention of open knee joint fracture. Methods: The data of 86 cases of open knee joint fracture admitted from January 2002 to December 2015 in Department of Orthopaedics, Affiliated Hospital of Chengdu University were analyzed retrospectively.There were 65 males and 21 females aged of 38.6 years. There were 38 cases treated with trans articular external fixation alone, 48 cases were in the trans articular external fixation plus auxiliary limited internal fixation group. All the patients were treated according to the same three stages except for different fixation methods. Observation of external fixation and fracture fixation, fracture healing, wound healing and treatment, treatment and related factors of infection control and knee function recovery. χ(2) test was used to analyze data. Results: Eleven patients had primary wound healing, accounting for 12.8%. Seventy-five patients had two wounds healed, accounting for 87.2%. Only 38 cases of trans articular external fixator group had 31 cases of articular surface reduction, accounting for 81.6%; Five cases of trans articular external fixator assisted limited internal fixation group had 5 cases of poor reduction, accounting for 10.4%; There was significant difference between the two groups (χ(2)=44.132, P<0.05). Take a single cross joint external fixation group, a total of 23 cases of patients with infection, accounted for 60.5% of external fixation group; trans articular external fixation assisted limited internal fixation group there were 30 cases of patients with infection, accounting for the assistance of external fixator and limited internal fixation group 62.5%; There was significant difference between the two groups(χ(2)=0.035, P>0.05). Five cases of fracture nonunion cases of serious infection, patients voluntarily underwent amputation. The Lysholm Knee Scale: In the external fixation group, 23 cases were less than 50 points, accounting for 60.5%, 15 cases were more than 50 points, accounting for 39.5%, external fixation and limited internal fixation group 20 cases were less than 50 points, accounting for 41.7%, 28 cases were more than 50 points, accounting for 58.3%; There was significant difference between the two groups(χ(2)=1.279, P>0.05). Conclusions: Prevention and control of infection is a central link in the treatment of open fracture of the knee. Trans articular external fixator plus limited internal fixation is an important measure to treat open fracture of the knee-joint.

Abstract
Plants maximize their fitness by adjusting their growth and development in response to signals such as light and temperature. The circadian clock provides a mechanism for plants to anticipate events such as sunrise and adjust their transcriptional programmes. However, the underlying mechanisms by which plants coordinate environmental signals with endogenous pathways are not fully understood. Using RNA-sequencing and chromatin immunoprecipitation sequencing experiments, we show that the evening complex (EC) of the circadian clock plays a major role in directly coordinating the expression of hundreds of key regulators of photosynthesis, the circadian clock, phytohormone signalling, growth and response to the environment. We find that the ability of the EC to bind targets genome-wide depends on temperature. In addition, co-occurrence of phytochrome B (phyB) at multiple sites where the EC is bound provides a mechanism for integrating environmental information. Hence, our results show that the EC plays a central role in coordinating endogenous and environmental signals in Arabidopsis.

Abstract
OBJECTIVE To summarize the clinical outcome of totally thoracoscopic cardiac surgery for mitral valve replacement. METHODS Clinical data of 634 cases undergoing totally thoracoscopic cardiac surgery for mitral valve replacement from May 2004 to February 2016 in Department of Thoracoscopic Cardiacsurgery, Shanghai Yodak Cardiothoracic Hospital was analyzed retrospectively. There were 292 male and 342 female patients, aged from 17 to 68 years with a mean of (45±13) years. All the 634 patients had moderate-severe mitral valve stenosis and (or) incompetence, 263 patients had moderate-severe tricuspid valve incompetence, 356 patients had atrial fibrillation, 46 patients had left atrium thrombosis. Cardiopulmonary bypass was established with right femoral artery and a single 2 stage venus cannula in the right atrium. The ascending aorta was cross-clamped and the myocardium was protected by coronary perfusion with cold crystalloid cardioplegia. Totally thoracoscopic mitral valve replacement were performed. RESULTS Thirteen cases had incision expanded and 8 cases had conversions to sternotomy. Cardiopulmonary bypass and aortic cross-clamp time were (89±18) minutes and (51±12) minutes, respectively. Operation time was (3.1±1.2) hours. Mechanical ventilation time and intensive care unit stay were (17±6) hours and (27±8) hours, respectively. Postoperation drainage quantity was (390±70) ml. The hospital days was (9.2±2.1) days. There were 5 cases in-hospital deaths. Postoperative complications occurred in 42 cases (6.6%), including 18 cases of right hemoneumothorax, 12 cases of reoperation for bleeding, 3 cases of perivalvular leakage (reoperation was done in 1 patient), 3 cases of low cardiac output syndrome, 2 cases of acute renal failure, 2 cases of inferior vena cava injury, 1 case of right femoral artery thrombosis and liver injury, respectively. The mean duration of follow-up was (58±9) months in 608 cases, with a follow-up rate of 96.7% (608/629). Three patients had died during the period of follow-up caused by congestive heart failure (2 patients) and stroke (1 patient). Late complication among 605 survivors were 37 cases, including 32 cases of moderate tricuspid valve insufficiency, 3 cases of stroke, 1 case of perivalvular leakage and infective endocarditis, respectively.There was no reoperation during the period of follow-up. CONCLUSION Totally thoracoscopic cardiac surgery for mitral valve replacement is safe and effective, with unique superiority and clinical feasible.
