Abstract
Background According to statistics, about one-fifth of the world's elderly people suffer from sleep disorders, and the problem of sleep disorders in the elderly is extremely serious, and this problem is one of the important causes of chronic diseases such as hypertension, hyperlipidemia, diabetes mellitus, and coronary heart disease in the elderly. The positive effect of Tai Chi exercise therapy on sleep problems has been confirmed, but at present, the effect of the specific duration of Tai Chi exercise on the improvement of elderly people with moderate to severe sleep disorders varies. Objective META analysis was used to investigate and find that long-term Tai Chi exercise therapy has the best effect on improving sleep in elderly patients with moderate to severe sleep disorders. Methods: META analysis was performed using Revman 5.3 after searching Web of science, Pubmed, Scopus, The Cochroae Library, OVID, CBM, CNKI, VIP, and other databases, and then filtering and extracting. Results A total of seven papers were included. Meta-analysis showed that tai chi exercise was more effective in improving sleep problems in elderly patients with sleep disorders compared to the control group, and the difference was significant. This was demonstrated by a decrease in the global Pittsburgh Sleep Quality Index (PSQI) score [SMD = -0.66, 95 % CI (-0.91, -0.41), P < 0.00001], as well as its subdomains of subjective sleep quality [SMD = -0.79, 95 % CI (-1.06, -0.52), P < 0.00001], sleep latency [SMD = -0.80, 95 % CI (-1.21, -0.40), P < 0.00001], sleep duration [SMD = -0.38, 95 % CI (-0.72, -0.04), P = 0.03], habitual sleep efficiency [SMD = -0.58, 95 % CI (-0.84, -0.31), P < 0.0001], sleep disturbance [SMD = -0.51, 95 % CI (-0.78, -0.25), P = 0.00001] and daytime dysfunction [SMD = -0.33, 95 % CI (-0.59, -0.07), P = 0.01]. Improvement was also observed in the Epworth Sleepiness Scale (ESS) and Insomnia Severity Index Scale (ISI). The results showed that the optimal duration and frequency of Tai Chi exercise therapy for improving moderately severe elderly patients with sleep disorders was long-term. Conclusion This study systematically assessed the efficacy of Tai Chi exercise therapy for elderly patients with moderate-to-severe sleep disorders. Through a meta-analysis of relevant randomized controlled trials (RCTs), it aims to determine the effectiveness of Tai Chi exercise in improving sleep quality in elderly patients with moderate-to-severe sleep disorders, as well as to compare its effects with those of traditional treatments; to analyze the safety of Tai Chi exercise for this patient population and assess its feasibility as a non-pharmacological therapy; and to fill the research gaps and provide more comprehensive and systematic evidence support. This study provides a practical approach to reducing the risk of medication side effects in older adults with sleep disorders and offers a potentially effective non-pharmacological treatment option, especially for those who are unable or unwilling to use medication. Tai chi exercise may not only improve sleep, but also improve coordination, muscle strength, balance, and reduce stress and anxiety in older adults. It also helps older adults socialize and enhances their social connections and emotional support. This study suggests that community centers or activity centers for the elderly can organize tai chi classes to promote the participation of older adults, and can be used as a scientific exercise rehabilitation tool in clinical treatment, incorporating tai chi practice into daily life, such as tai chi practice at a fixed time every day or every week, which not only helps to improve the sleep disorders of older adults, but also improves their overall quality of life.

Abstract
BACKGROUND The local hemodynamic response after cupping therapy has been considered as a contributing factor for improving muscle tissue health; however, the effects of cupping pressure and duration on the spatial hemodynamic response have not been investigated. OBJECTIVE The objective of this study was to investigate the hemodynamic response inside and outside the cupping cup under various pressures and durations of cupping therapy. METHODS A 3-way factorial design with repeated measures was used to investigate the main and interaction effects of the location (areas inside and outside the cup), pressure (-225 and -300 mmHg) and duration (5 and 10 min) on the hemodynamic response of the biceps muscle. A functional near-infrared spectroscopy was used to assess hemodynamic changes in 18 participants. RESULTS A significant three-way interaction of the location, pressure, and duration factors was observed in oxyhemoglobin (p= 0.023), deoxy-hemoglobin (p= 0.013), and blood volume (p= 0.013). A significant increase was observed in oxyhemoglobin, blood volume, and oxygenation compared to pre-cupping (p< 0.05) in the area outside the cup. CONCLUSION Our findings indicate that an appropriate combination of cupping pressure and duration can effectively affect the spatial hemodynamic response of the biceps.

Abstract
Sporotrichosis, a fungal infection caused by Sporothrix species, can greatly lead to chronic inflammation of the skin, mucosa, and lymphatic vessels and disseminate systemically sometimes, even threatening life. It is known that Sporothrix is distributed worldwide, while in China, most of the cases were reported in northeast China and parts of south China. Sporothrix globosa is the main source of infection, and other regions may lack relevant awareness and attention to the disease, making it a public health challenge in China. Thus, it is important to understand its epidemiology and public health risks to prevent and control the disease properly.

Abstract
Background Tai Chi (Bafa Wubu) is a new type of simplified Tai Chi widely practiced by Tai Chi enthusiasts that has developed and perfected simplified Tai Chi movement and enriched Tai Chi practice methods. When practicing, Tai Chi athletes and enthusiasts can choose the Bafa Wubu movements to practice according to their physical conditions. The purpose of this article is to discuss the mechanism by which Bafa Wubu promotes lower extremity exercise from the perspective of exercise biomechanics. Objectives This article aims to explore the scientific training methods and technical characteristics of Bafa Wubu, and its contribution to comprehensive exercise of the lower extremities, by analyzing the biomechanical characteristics of the lower extremities of participants who practice Bafa Wubu at different levels and by comparing their ground reaction force, lower limb joints, and muscles during Bafa Wubu. Methods A total of 16 male participants were recruited and divided into an amateur group (N = 8) and a professional group (N = 8). The data were collected by a BTS 3D infrared-based motion capture system, and Kistler 3D force plate. The lower extremity joint forces and muscle strength were calculated by anybody simulation software with inverse dynamics. Results During elbowing and leaning sideways with steps sideways (ELS), the ground reaction force of the professional group was significantly higher than that of the amateur group in the sagittal, vertical, and frontal axes (P < 0.01). While stepping forward, backward, and sideways, the professional group's joints loading at the hip, knee, and ankle was always higher in the vertical direction (P < 0.01). Furthermore, during warding off with steps forward (WOF), laying with steps forward (LF), and rolling back with steps backward (RBB), hip joint loading increased in the med-lat direction. During actions with steps backward and sideways, the professional group's ankle flexion/extension torque and hip abduction/rotation torque were significantly larger than those of the amateur group (P < 0.01). Different actions in Bafa Wubu activate muscles to different degrees, whereas the iliacus is mainly responsible for stabilizing postures when practitioners perform standing knee lifting motions. Conclusions Professional groups who have been practicing Tai Chi (Bafa Wubu) for a long time have higher ground reaction force, and the force on the three joints of the lower extremities is different for various movements, which has positive significance for exercising the joints of the lower extremities. In addition, various motions activate muscles of different types at different levels. For amateurs to practice different movements to stimulate the muscles, targeted areas of practice promote the lower extremity muscles' synergistic force. In summary, the muscles and joints of the lower extremity can obtain comprehensive and balanced exercise through Bafa Wubu.

Abstract
BACKGROUND By comparatively investigating the joints, muscles and bones of the lower extremity during two progressive motions in Bafa Wubu and normal walking, this paper aims to enrich the diversity of walking exercise and scientifically provide theoretical guidance for primary practitioners. The scientific training methods and technical characteristics of Bafa Wubu, as well as its contribution to comprehensive exercise of the lower extremities, are further explored. METHODS A total of eight professional athletes of Tai Chi at the national level were recruited. The kinetic parameters of the lower extremity were calculated using AnyBody 7.2 musculoskeletal modeling. Stress analysis of the iliac bone was performed using an ANSYS 19.2 workbench. RESULTS In Bafa Wubu, the ground reaction force during two progressive motions was significantly smaller than that noted during normal walking. During warding off with steps forward and laying with steps forward, the load at the three joints of the lower extremity was significantly smaller than that during normal walking in the frontal plane, but significantly greater than that noted during normal walking in the vertical axis. In addition, the lower limb joint torque was higher than that of normal walking in both progressive movements, and lower limb muscle activation was higher. The iliac bone loads during the two progressive motions were larger than those during normal walking, and the maximum loading point differed. CONCLUSIONS This is the first study to demonstrate the biomechanical performance of Bafa Wubu in professional athletes of Tai Chi. Two progressive motions of Bafa Wubu require the lower extremity to be slowly controlled, thereby resulting in a smaller ground reaction force. In addition, the loads of the three joints at the lower extremity all increase in the vertical direction and decrease in the lateral direction, reducing the possibility of lateral injury to the joints. In addition, the two progressive motions significantly enhance the muscle strength of the plantar flexion muscles, dorsiflexor, and muscles around the thigh, and effectively stimulate the bones of the lower extremity. Therefore, progressive motion training contributes to improving the controlling and supporting capabilities of the lower extremities during normal walking.

Abstract
Objective: This pilot study aimed to explore the mechanism of the effects of Bafa Wubu of Tai Chi (BWTC) on anxiety and depression in college students using resting-state functional magnetic resonance imaging (RS-fMRI). Methods: Eighteen college students (5 males and 13 females) with anxiety and depression met the study criteria and were randomly divided into an experimental group (aged 24.20 ± 4.07 years) and a control group (aged 22.50 ± 5.95). The experimental group received an eight-week BWTC intervention five times/week for 60 min/session. The control group maintained normal daily life without any exercise intervention. These students were assessed using RS-fMRI scans, the self-rating anxiety scale (SAS), and the self-rating depression scale (SDS). Spearman correlation analysis was used, and statistical significance was defined as a two-sided p-value of <0.05. Results: After the intervention, the SAS and SDS scores of the BWTC group significantly reduced (p = 0.002; p = 0.001). Compared with the control group, the fALFF values of the right middle frontal gyrus, orbital part (Frontal_Mid_Orb_R) (p = 0.043), right inferior occipital gyrus (Occipital_Inf_R) (p = 0.003), and right middle temporal gyrus of the temporal pole (Temporal_Pole_Mid_R) (p = 0.003) in the BWTC group increased significantly; the fALFF values of the left middle frontal gyrus (Frontal_Mid_L) (p = 0.001) and right supplementary motor area (Supp_Motor_Area_R) (p = 0.010) in BWTC group decreased significantly. The fALFF values of Frontal_Mid_Orb_R were significantly positively correlated with the SDS score (r = 0.852, p = 0.015) and the fALFF values of Frontal_Mid_L were significantly negatively correlated with the SAS score (r = -0.797, p = 0.032). Conclusion: In this pilot study with college students, BWTC alleviated anxiety and depression, potentially through modulating activity in the Frontal_Mid_L and Frontal_Mid_Orb_R, respectively.

Abstract
The electric stair-climbing wheelchair is a beneficial mobile assistance device for older adults and disabled persons with poor walking ability, as it reduces the daily walking and climbing burden. In this paper, 11 older adults were tested when using a stair-climbing wheelchair in three environments: flat ground, slopes, and stairs. The kinematic and dynamic parameters of the lower limb joints were simulated by AnyBody 7.2 human model simulation software using Vicon 3D infrared motion capture, a 3D force table, and analyzed by ANSYS 19.2 Workbench. The joint force, joint moment, and muscle strength did not change significantly under the three environments when using the wheelchair. Through finite element analysis of the mechanical properties of the human body, when using the wheelchair, no significant differences in the overall stress distributions of the fifth lumbar spine, hip bone, or femur were found among the three environments, no significant differences in deformation and displacement were found, and the stress distribution was relatively stable. Therefore, the human body is stable enough to use the electric stair-climbing wheelchair in the three test environments, all of which will be commonly encountered in daily life.

Abstract
OBJECTIVE We explored the effectiveness of an online/offline mixed-mode Tai Chi cardiac rehabilitation program on the microcirculation of patients with coronary artery disease (CAD). DESIGN Prospective, randomized controlled study. SETTING It was conducted in a tertiary hospital. SUBJECTS Twenty-six patients who met the diagnostic criteria for coronary artery disease were recruited. INTERVENTIONS Patients were randomized divided into a 12-week Tai Chi cardiac rehabilitation program(TCCRP) or a conventional exercise rehabilitation program(CERP) in a 1:1 fashion, 4 weeks of in-hospital rehabilitation and 8 weeks of online rehabilitation at home (a total of 12 weeks of intervention). MAIN OUTCOME MEASURES Nailfold microcirculation (Morphological integrals, Blood flow integrals, Periphery capillary loop integrals, Overall integrals). MAIN OUTCOME MEASURES Twenty patients completed the study. The Morphological integrals (baseline: 2.875±1.171 vs 12weeks: 1.863±0.414, t = 2.432, P = 0.045 < 0.05) and Overall integrals (baseline: 5.563±2.001 vs 12weeks: 3.688±1.167, t = 3.358, P = 0.012 < 0.05) decreased significantly in the TCCRP, The nailfold microcirculation integra decreased not significantly in the CERP (P > 0.05). The nailfold microcirculation integra was not significantly different between the two groups after the intervention (P > 0.05). CONCLUSIONS The TCCRP improved the microcirculation of patients with CAD.

Abstract
Cupping therapy has been used for the alleviation of muscle soreness in athletes. However, clinical studies of cupping therapy show conflicting results. Lack of standardized guidelines of the dose-response relationship of cupping therapy, such as appropriate cupping duration and negative pressure, limits the adoption of cupping therapy in clinical practice. The objectives of this study were to investigate the effect of various pressures and durations of cupping therapy on reducing muscle stiffness. The 2 × 2 factorial design with the repeated measures and counterbalanced design was used to test four cupping protocols, including two negative pressures at -225 and -300 mmHg and two durations at 5 and 10 min, in 12 healthy young people. B-mode and elastographic ultrasound was used to assess muscle stiffness of the triceps before and after cupping therapy. The region of interest of elastographic image was divided into the superficial and deep layers for assessing the effect of cupping therapy on stiffness of various depths of the triceps. Normalized stiffness was calculated as a ratio of pre-cupping stiffness divided by post-cupping stiffness of each participant. The two-way analysis of variance (ANOVA) was used to examine the main effects of the pressure and duration factors and the interaction effect between the pressure and duration factors. The results showed that there were no interactions between the pressure and duration factors (overall layer p = 0.149, superficial layer p = 0.632, and deep layer p = 0.491). The main effects of duration of the overall, superficial and deep layers were p = 0.538, p = 0.097 and p = 0.018, respectively. The results showed that 10-min cupping at -300 mmHg is more effective on reducing stiffness of the deep layer of the triceps compared to 5-min cupping (p = 0.031). This study provides the first evidence that the dose of cupping therapy could significantly affect changes of triceps stiffness and the deep layer of the muscle is more sensitive to cupping therapy compared to the superficial and overall layers.

Abstract
Objective: To explore the correlation between blood glucose levels and the three factors of sarcopenia (muscle mass, strength and function) in older Chinese community dwellers. Methods: This is a retrospective study conducted by collecting the data of patients in Jiangsu Huaqiao Road Community Health Service Center from 2018 to 2019. Two hundred and fifty people aged 60 years or elder were selected. Among them, 101 were men and 149 were women. According to the American Diabetes Association diagnostic criteria for diabetes mellitus in 2018, they were divided into normal glucose tolerance (NGT) group, pre-diabetes group and diabetes group. The patients were assessed for sarcopenia as well. Results: Compared with those in the NGT group, muscle mass and upper limb muscle strength did not change in the diabetic group, but lower limb muscle strength and body function [walking speed, balance, short physical performance battery (SPPB)] decreased significantly in the diabetic group. Pearson correlation analyses showed that fasting plasma glucose(FPG) was negatively correlated with walking speed (r=-0.248, P=0.001), three-pose balance (r=-0.166, P=0.013) and SSPB (r=-0.213, P=0.001). Glycosylated hemoglobin A1c(HbA1c) was positively correlated with sitting and standing time (r=0.205, P=0.002), and negatively correlated with three-pose balance (r=-0.186, P=0.006) and SSPB (r=-0.154, P=0.024). Multiple regression analyses showed that FPG was negatively associated with walking speed (β=-0.125, P=0.005) and SPPB (β=-0.034, P=0.012), and that HbA1c was positively associated with sitting and standing time (β= 0.218, P =0.006) and negatively associated with three-pose balance (β=-0.143, P=0.012), and SPPB (β=-0.117, P =0.036). Conclusions: There is no significant correlation between blood glucose levels and muscle mass in the elderly; however, FPG is closely correlated with gait speed, and HbA1c is closely correlated with muscle strength of lower limbs and balance ability in the elderly.

Abstract
Abstract
Background
Standard scoring system for bleeding risk assessment has not been developed in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). The study aims to evaluate the predictive value of the HAS-BLED, ORBIT, ARTIA, PARIS, and PRECISE-DEAPT score in patients with AF and ACS/PCI who received both anticoagulant and antiplatelet therapy.
Methods
A total of 930 patients with AF and ACS/PCI receiving both anticoagulant and antiplatelet therapy were consecutively recruited and followed up for 1 year. The primary endpoint was defined according to the bleeding academic research consortium (BARC) criteria as major (BARC 3a, 3b, 3c, and 5) and any bleeding (BARC 2, 3a, 3b, 3c, and 5). The secondary endpoints included major or minor bleeding according to TIMI criteria. Univariate and multivariate logistic regression were performed to evaluate the association between bleeding risk scores and outcomes. Receiver operating characteristic (ROC) curves were constructed and c-statistics were calculated to evaluate the predictive performance of different bleeding risk scores.
Results
BARC class ≥2 bleedings occurred in 36 patients (3.9%), while BARC class ≥3 bleedings were seen in 134 patients (14.4%). The HAS-BLED, ORBIT, ARTIA, PARIS, and PRECISE-DEAPT score were significantly associated with incidences of BARC class ≥2 and ≥3 bleedings during 1-year follow-up (all p<0.05). The ROC analysis showed that the predictive performance of the five bleeding risk scores for BARC class ≥3 bleedings were low-to-moderate [c-statistic: HASBLED 0.584 (0.552–0.616), ATRIA 0.624 (0.592–0.655), ORBIT 0.623 (0.591–0.654), PARIS 0.633 (0.601–0.664), PRECISEDAPT 0.616 (0.584–0.647)]. Multivariable logistic regression indicated that previous bleeding history and hemoglobin were independent predictors of BARC class ≥3 bleedings. Compared to the HAS-BLED score, the model constructed by previous bleeding history and hemoglobin displays a significant improvement in bleeding risk prediction (0.704 vs. 0.584, p=0.013).
Conclusions
In patients with AF and ACS/PCI receiving both anticoagulant and antiplatelet therapy, the HAS-BLED, ORBIT, ARTIA, PARIS, and PRECISE-DEAPT score displayed low-to-moderate performance for predicting BARC class ≥3 bleedings during 1-year follow-up. More accurate scoring systems for bleeding risk evaluation should be developed for these patients in the future.

Abstract
Abstract
Background
This study aimed to evaluate the association between plasma big endothelin-1 (ET-1) level and the severity of coronary artery disease assessed by the SYNTAX score (SS) in patient with non-ST segment-elevated myocardial infarction (NSTEMI).
Methods
A total of 766 patients with NSTEMI undergoing coronary angiography were recruited. Patients were divided into divided into three groups: low SS (SS ≤22), intermediate SS (23–32) and high SS group (SS >32). Spearman correlation, smooth curve fitting, logistic regression and Receiver operating characteristic (ROC) curve analysis were performed to evaluated the association between plasma big ET-1 level and the SS.
Results
There was a significant correlation between the big ET-1 and the SS (r=0.378, p<0.001). Smoothing curve indicated a positive correlation between plasma big ET-1 level and the SS, after adjustment for potential confounders. The ROC curve analysis showed that the area under the curve was 0.695 (0.661–0.727) and the optimal cutoff of plasma big ET-1 level were 0.35pmol/l, with a sensitivity of 68.9% and a specificity of 62.9%. Logistic regression showed that elevated big ET-1 was an independent predictor of intermediate-high SS in patients with NSTEMI, no matter entered as a continuous variable [OR (95% CI): 1.110 (1.053–1.170), p<0.001] or as a categorical variable [OR (95% CI): 2.873 (2.016–4.094), p<0.001]. The association between big ET-1 and intermediate-high SS was consistent across subgroups without significant interactions.
Conclusion
In patients presenting with NSTEMI, plasma big ET-1 level was significantly correlated with the SS. Elevated plasma big ET-1 level was an independent predictor for intermediate-high SS.

Abstract
Abstract
Objective
The Global Registry of Acute Coronary Events (GRACE) score is recommended for risk stratification for patients with ST-segment elevation myocardial infarction (STEMI) by clinical guidelines. Data about comorbidities were not incorporated in the GRACE score. This study aimed to evaluate the incremental predictive value of adding the CHA2DS2-VASc score to the GRACE score for in-hospital mortality in patients with STEMI.
Methods
7476 patients with STEMI were recruited and divided into five groups according to the CHA2DS2-VASc score (1, 2, 3, 4 and ≥5 points) at admission. The primary outcome was defined as in-hospital mortality, while the secondary outcomes were recurrent MI, stroke and major adverse cardiovascular events (MACE) during hospitalization. Univariate and multivariate logistic regression were performed to evaluate the association between the CHA2DS2-VASc score and outcomes. Incremental predictive performance of adding the CHA2DS2-VASc score to the GRACE score were evaluated through analysis of the receiver operating characteristic (ROC) curves, net reclassification improvement (NRI) and integrated discrimination improvement (IDI).
Results
With the increase of CHA2DS2-VASc score, patients with STEMI tended to have more comorbidities, receive less evidence-based treatments and carry worse in-hospital outcomes. Multivariate logistic regressions demonstrated that the CHA2DS2-VASc score was an independent predictor for in-hospital mortality [OR (95% CI): 1.320 (1.238–1.407), p<0.001], recurrent myocardial infarction [OR (95% CI): 1.233 (1.086–1.401), p=0.001], stroke [OR (95% CI): 1.433 (1.207–1.702), p<0.001] and MACE [OR (95% CI): 1.146 (1.088–1.207), p<0.001]. The c statistic value of combining the GRACE score with the CHA2DS2-VASc score was significantly higher than that of the GRACE score alone in predicting in-hospital mortality (0.784, 95% CI: 0.774–0.793 vs. 0.769, 95% CI: 0.760–0.779, z=4.180, p<0.001). The addition of the CHA2DS2-VASc score to the GRACE score resulted in significantly improved predictive performance for in-hospital mortality, with a NRI of 0.356 (95% CI: 0.280–0.432, p<0.001) and a IDI of 0.013 (95% CI: 0.009–0.018, p<0.001).
Conclusion
The CHA2DS2-VASc score was an independent predictor of in-hospital outcomes in patients with STEMI. Compared to the GRACE score alone, the addition of the CHA2DS2-VASc score to the GRACE score improved the predictive performance for in-hospital mortality in patients STEMI.

Abstract
At present, coronavirus disease 2019 (COVID-19) has become a global public health emergency, bringing a great threat to human health. This study aims to evaluate and analyze the factors that influence the quality of life (QOL) of patients with coronary heart disease (CHD) during COVID-19 to provide a realistic basis for improving their QOL. A total of 70 patients with CHD were selected through convenience sampling from three heart rehabilitation centers. The cross-sectional survey of the study cases were carried out using an online survey platform. All of the participants completed a general situation questionnaire, and QOL was assessed through the 36-item Short Form Health Survey. Results showed that the overall QOL of patients with CHD during COVID-19 was poor, having an average score of 65.99 ± 10.97. Moreover, multivariate linear regression analysis showed that worry about COVID-19 (P < 0.05) and different exercise intervention types (P < 0.05) were the main factors affecting the QOL of patients. On the one hand, positive measures should be taken to provide psychological counseling to ease their sense of concern. On the other hand, engaging in exercise is more important for these patients to improve physical function, particularly Tai Chi exercises.

Abstract
Background The newly compiled Bafa Wubu of Tai Chi (Eight Methods and Five Footworks) is a fitness routine that has been developed in accordance with the appeal of the General Administration of Sport of China and promoted both in China and abroad. This paper aims to compare the differences in energy consumption and related parameters between the two types of Tai Chi. Methods A total of 60 healthy participants were recruited; 37 males (aged 37.4 ± 10.4 years) and 23 females (aged 31.9 ± 12.8 years). The maximal exercise capacity of participants was measured at baseline. Then, they received Tai Chi training for 12-week and their energy metabolism was measured dynamically. Results A set of the Bafa Wubu of Tai Chi requires approximately 3 min, while a set of 24 form simplified Tai Chi approximately 5 min and 40 s. The average oxygen uptake/kg (VO2/kg, 10.8 ± 2.52 ml/kg/min vs. 12.9 ± 2.59 ml/kg/min, P = 0.000), the highest VO2/kg (19.3 ± 6.03 ml/kg/min vs. 24.1 ± 7.50 ml/kg/min, p = 0.000, the average metabolic equivalent (METs,2.3 ± 0.16 METs vs. 3.2 ± 0.14 METs, p = 0.000), the highest oxygen pulse (VO2/HR, 11.1 ± 0.99 ml vs. 13.9 ± 0.93 ml, p = 0.000) and rate of perceived exertion (RPE, 10.7 ± 0.70 vs. 1.3 ± 0.62, p = 0.000) gained immediately after Bafa Wubu of Tai Chi exercise were significantly lower than those in 24 form simplified Tai Chi; heart rate recovery (HRR,1.5 ± 0.41 vs. 1.3 ± 0.45, p = 0.008) at 1 min after the practice was significantly higher than after the 24 form simplified Tai Chi. Meanwhile, the average heart rate (HR, 104.1 ± 11.41 bpm vs. 105.7 ± 9.68 bpm, p = 0.696) and the highest respiratory quotient (RQ, 1.0 ± 0.06 vs. 0.9 ± 0.09, p = 0.643) were not significantly different. The intensity of Tai Chi was described as the highest oxygen uptake of the participants when they performed the Tai Chi divided by their individual maximal oxygen uptake. Tai Chi intensity during Bafa Wubu of Tai Chi (50% ± 11.7% vs. 64% ± 12.5%) was significantly lower than during 24 form simplified Tai Chi. Conclusion The newly compiled Bafa Wubu of Tai Chi is characterized by lower energy consumption than 24 form simplified Tai Chi.

Abstract
Background:Interstitial lung diseases (ILD) could originate from idiopathic cause or secondary to connective tissue diseases (CTD). The most common causes of CTD associated ILD (CTD-ILD) include mixed connective tissue disease, systemic sclerosis (SSc), inflammatory myositis such as polymyositis (PM) and dermatomyositis (DM). Our preliminary data had demonstrated that ILD is not uncommon in patients with rheumatoid arthritis (RA) and Sjogren’s syndrome (SS) in Asia. Myositis-specific autoantibodies (MSAs) and myositis associate autoantibodies (MAAs) have been used for the early diagnosis of PM/DM and could be noticed in patients with idiopathic ILD. Our previous data also had identified that MSA/MAA were detected quite often in patients with CTD-ILD in addition to inflammatory myositis. Nonetheless, a specific group of ILD patients like interstitial pneumonia with autoimmune features (IPAF) are still challenging for pomologists, rheumatologist and radiologists, either in accurate diagnosis or treatment.Objectives:We aimed to identify the prevalence of serum MSA/MAAs and clinical diagnosis on imaging in patients with IPAF and CTD-ILD and define the correlation between MSA/MAA and clinical imaging features.Methods:Patients who had been suspected with autoimmune rheumatic diseases in the presence of interstitial lung diseases were included in this prospective study at a single medical center in Taiwan between February 2018 and November 2019. All enrolled patients had experienced clinical symptoms of ILD and been identified abnormalities on the chest plain films. All patients were inspected by both pulmonologists and rheumatologist. Computed tomography scans of chest had been reviewed by at least two pulmonary radiologists. Serological immunotherapy strips were performed to detect MSA/MAAs. Correlation analysis was performed among the different collected variables.Results:870 patients were reviewed by both pulmonologists and rheumatologists and received blood sampling including autoantibody profiling and MSA/MAA tests. The clinical diagnosis of CTD-ILD or IPAF were confirmed in 603 patients, who received 1078 chest CT scan due to clinically suspected CTD-ILD or IPAF. 33 patients received lung biopsies since other CTD-ILD or IPAF patients hesitate to receive invasive procedures. 78 patients had been admitted to intensive care units and received mechanical ventilation and were not suitable for lung biopsies. 22 of 33 patients received more than twice lung biopsies due to challenging diagnosis. 6 patients with CTD-ILD or IPAF had received extracorporeal membrane oxygenation (ECMO) due to ILD with secondary pulmonary infection and acute respiratory distress syndrome. The most commom detected MSA/MAA were anti-Ro-52 (27%), followed by anti-Ku (3.9%), and anti-Mi-2 (3.6%).SS is the most common rheumatic disease in patients with CTD-ILD. MSA/MAAs were identified in patients with IPAF (36.4 %) in the absence of specific rheumatic diseases. Anti-nuclear antibody (27.4%), rheumatoid factor immunoglobulin M (21.6%) and anti-Ro (13.7%) were the most common autoantibodies identified in patients with IPAF. Anti-Ro-52 was positively corelated with nonspecific interstitial pneumonia in patients with CTD-ILD or IPAF, Phi= 0.371 and 0.326, both p < 0.001, respectively.Conclusion:Early diagnosis of CTD-ILD and IPAF is still challenging for both pulmonologists, rheumatologists and radiologists. Identifying how serum MSA/MAAs contribute clinical manifestations on chest CT imaging is warranted and help clinical physicians and patients recognize the necessity of lung biopsy to reduce comorbidity.References:[1]Jee AS, et al.

Abstract
Objective: To compare the efficacy and safety of active transfer of plaque (ATP) versus provisional stenting (PS) with drug-eluting stents (DES) for the treatment of coronary bifurcation lesions. Methods: A total of 1 136 patients with bifurcation lesions hospitalized in 6 selected hospitals between January 2010 and January 2014 were included in this prospective observational trial, patients were divided into either ATP (n=560) or PS group (n=576) accordingly. The primary endpoint was target lesion revascularization within 1 year, and the second endpoints were all-cause death, cardiogenic death, myocardial infarction, stent thrombosis, stroke, recurrent angina within 1 year. Results: There were no significant differences in age, sex, hypertension, diabetes, hyperlipidemia and smoking history between the two groups (P>0.05). The incidence of TIMI blood flow <3 grade in the side branch (1.6%(9/560) vs. 7.5% (43/576), P<0.01), acute occlusion of the side branch (1.3%(7/560) vs. 7.1%(41/576), P<0.01) and implanted stents of side branch (1.8%(10/560) vs. 7.8% (45/576), P<0.01) were significantly lower in the ATP group than those in the PS group. During the one year follow up, the rate of target lesion revascularization was similar between ATP group and PS group (4.6%(26/560) vs. 4.0%(23/576), P=0.66). Conclusions: The effectiveness and safetyof ATP techniquein the patients with coronary bifurcation lesions is comparable to the PS technique. However, ATP technique is superior to PS technique on effectively reducing the incidence of implanted stents in the side branch.

Abstract
Objective: To investigate the concept of hepatitis B virus (HBV)-related acute-on-chronic pre-liver failure (pre-ACLF), and to develop and evaluate the diagnostic criteria for this disease. Methods: A retrospective analysis was performed for the clinical data of 754 patients with severe acute exacerbation (SAE) of HBV-related chronic liver disease, and their clinical features were identified. A multivariate logistic regression analysis was used to determine the risk factors for acute-on-chronic liver failure (ACLF). The inclusion rate of patients with SAE-HBV-related chronic liver disease and the detection rate of ACLF patients were analyzed to evaluate the value of four different versions of diagnostic criteria for pre-liver failure. The t-test, an analysis of variance, the Mann-Whitney U test, and the chi-square test were used for statistical analysis based on data type. Results: The incidence rate of ACLF in the patients with SAE-HBV-related chronic liver disease was 9.9% and the time to progression to ACLF was 12.0 ± 6.7 days. The multivariate logistic regression analysis showed that HBV reactivation (odds ratio [OR] = 5.118), direct bilirubin ratio (D/T) (OR = 1.041), age (OR = 1.033), total bilirubin (TBil) (OR = 1.005), prothrombin activity (PTA) (OR = 0.880), and serum sodium (Na) (OR = 0.918) were independent risk factors for ACLF. Group B (51.3 μmol/L < TBil < 171.1 μmol/L and 40%≤PTA < 60%, 4.2%) had a significantly lower incidence rate of ACLF than group A (51.3 μmol/L < TBil < 171.1 μmol/L and PTA < 40%, 13.7%) and group C (TBil > 171.1 μmol/L and 40% < PTA < 60%, 20.3%) (P < 0.001). Group C had a significantly shorter time to progression to ACLF than group A (10.5 ± 6.1 days vs 15.6 ± 7.4 days, P = 0.008). A total of 45 patients met the diagnostic criteria developed by Chongqing and the incidence rate of ACLF was 2.2%; 154 patients met the diagnostic criteria developed by Zhejiang and the incidence rate of ACLF was 7.1%; 188 patients met the diagnostic criteria in the Chinese guidelines and the incidence rate of ACLF was 6.4%; 117 patients met the diagnostic criteria for SAE-CHB and the incidence rate of ACLF was 9.4%. Conclusion: At present, these four versions of diagnostic criteria for pre-liver failure are not fully applicable to the clinical practice in China. The diagnostic criteria for HBV-related pre-ACLF should include important assessment indices which affect its progression to ACLF.

Abstract
Photosynthetic microalgae can capture solar energy and convert it to bioenergy and biochemical products. In nature or industrial processes, microalgae live together with bacterial communities and may maintain symbiotic relationships. In general interactions, microalgae exude dissolved organic carbon that becomes available to bacteria. In return, the bacteria remineralize sulphur, nitrogen and phosphorous to support the further growth of microalgae. In specific interactions, heterotrophic bacteria supply B vitamins as organic cofactors or produce siderophores to bind iron, which could be utilized by microalgae, while the algae supply fixed carbon to the bacteria in return. In this review, we focus on mutualistic relationship between microalgae and bacteria, summarizing recent studies on the mechanisms involved in microalgae-bacteria symbiosis. Symbiotic bacteria on promoting microalgal growth are described and the relevance of microalgae-bacteria interactions for biofuel production processes is discussed. Symbiotic microalgae-bacteria consortia could be utilized to improve microalgal biomass production and to enrich the biomass with valuable chemical and energy compounds. The suitable control of such biological interactions between microalgae and bacteria will help to improve the microalgae-based biomass and biofuel production in the future.

Abstract
In our previous research, we identified a QTL with an interval of 3.4 Mb for growth on chicken chromosome (GGA) 4 in an advanced intercross population of an initial cross between the New Hampshire inbred line (NHI) and the White Leghorn inbred line (WL77). In the current study, an association analysis was performed in a population of purebred white layers (WLA) with White Leghorn origin. Genotypic data of 130 SNPs within the previously identified 3.4-Mb region were obtained using a 60K SNP chip. In total, 24 significant SNPs (LOD ≥ 4.44) on GGA4 were detected for daily weigh gain from 8 to 14 weeks and two SNPs (LOD ≥ 4.80) for body weight at 14 weeks. The QTL interval was reduced by 1.9 Mb to an interval of 1.5 Mb (74.6-76.1 Mb) that harbors 15 genes. Furthermore, to identify additional loci for chicken growth, a genome-wide association study (GWAS) was carried out in a WLA population. The GWAS identified an additional QTL on GGA6 for body weight at six weeks (19.8-21.2 Mb). Our findings showed that by using a WLA population we were able to further reduce the QTL confidence interval previously detected using a NHI × WL77 advanced intercross population.

Abstract
OBJECTIVE To investigate the risk factors for the short-term outcome of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF), and to establish a risk model for predicting the short-term outcome of these patients. METHODS A total of 338 patients with HBV-related ACLF who were admitted to 30 Lod hospital of PLA hospital from January 2010 to January 2014 were enrolled, and a prospective clinical follow-up was performed for them. Multivariate logistic regression was used to determine the risk factors for short-term (12 weeks) outcome, the predictive model with logistic regression equation was established, and the predictive value of this model was evaluated. RESULTS The multivariate logistic regression analysis showed that age, a family history of hepatitis B, hepatic encephalopathy (HE), hepatorenal syndrome (HRS), white blood cell (WBC), platelet (PLT), international normalized ratio (INR), total bilirubin (TBil), total bile acid (TBA), creatinine, Na, HBV DNA, and HBeAg were the independent risk factors for the short-term outcome of these patients. Logistic(p) = -4.466 + 1.192 age + 1.631 family history of hepatitis B + 1.091 HE + 1.631 HRS + 1.208 WBC -1.487 PLT + 1.092 INR + 1.446 TBil + 1.608 TBA -1.101 CHE + 1.279 CRE -1.713 Na + 1.032 HBV DNA + 0.833 HBeAg. The area under the receiver operating characteristic curve of the model for the prediction of short-term outcome was 0.930, the cut-off value was 3.16, the sensitivity was 0.860, and the specificity was 0.871. With the increasing scores of the equation, the mortality of patients tended to increase gradually. CONCLUSION Age, a family history of hepatitis B, HE, HRS, WBC, PLT, INR, TBil, TBA, CHE, CRE, Na, HBV DNA, and HBeAg are the independent risk factors for the short-term outcome of patients with HBV-related ACLF. The model for predicting short-term outcome established on the basis of independent risk factors has a better clinical value in guiding clinical therapy.

Abstract
In our previous research, QTL analysis in an F2 cross between the inbred New Hampshire (NHI) and White Leghorn (WL77) lines revealed a growth QTL in the distal part of chromosome 4. To physically reduce the chromosomal interval and the number of potential candidate genes, we performed fine mapping using individuals of generations F10 , F11 and F12 in an advanced intercross line that had been established from the initial F2 mapping population. Using nine single nucleotide polymorphism (SNP) markers within the QTL region for an association analysis with several growth traits from hatch to 20 weeks and body composition traits at 20 weeks, we could reduce the confidence interval from 26.9 to 3.4 Mb. Within the fine mapped region, markers rs14490774, rs314961352 and rs318175270 were in full linkage disequilibrium (D' = 1.0) and showed the strongest effect on growth and muscle mass (LOD ≥ 4.00). This reduced region contains 30 genes, compared to 292 genes in the original region. Chicken 60 K and 600 K SNP chips combined with DNA sequencing of the parental lines were used to call mutations in the reduced region. In the narrowed-down region, 489 sequence variants were detected between NHI and WL77. The most deleterious variants are a missense variant in ADGRA3 (SIFT = 0.02) and a frameshift deletion in the functional unknown gene ENSGALG00000014401 in NHI chicken. In addition, five synonymous variants were discovered in genes PPARGC1A, ADGRA3, PACRGL, SLIT2 and FAM184B. In our study, the confidence interval and the number of potential genes could be reduced 8- and 10- fold respectively. Further research will focus on functional effects of mutant genes.

Abstract
OBJECTIVE To evaluate the effect of auscultation, partial pressure of carbon dioxide in end-expiration (P(ET)CO2), transillumination technique to judge whether the endotracheal tube is misplaced into the esophagus. METHODS A blinded randomized controlled trial was conducted. Sixty patients with American Society of Anesthesiology (ASA) grade I - II undergoing endotracheal intubation in Fengxian Central Hospital admitted from September 2014 to February 2015 were enrolled. Two endotracheal tubes with the same size were respectively inserted into the trachea and esophagus for the same depth after general anesthesia by the same person. Two blinded anesthetists with different experience checked the tube position using three methods including auscultation, P(ET)CO2, and transillumination technique, respectively. The order of the tubes tested (trachea or esophagus) and the method used were randomized according to randomise numbers table. The experienced anesthetists conducted the test first, followed by an inexperienced anesthetist conducting the same methods. The numbers of right and wrong determinations with different methods by different anesthetists were recorded. RESULTS Sixty patients underwent the procedures for 180 times, with intratracheal intubation for 90 times, and esophageal intubation for 90 times. It was shown that the results were not different in two groups [96.7% (174/180) vs. 92.2% (166/180), χ2 = 3.500, P = 0.057]. By using auscultation, the correct rate of experienced anesthetist was higher than that of inexperienced (95.0% vs. 78.3%, χ2 = 5.786, P = 0.013). Using P(ET)CO2, both anesthetists were correct in all cases, and the accuracy was 100%. Using transillumination, the experienced anesthetist was mistaken in 3 cases (accuracy was 95.0%), while the inexperienced mistook in 1 case (accuracy was 98.3%), and no significant difference was found between two groups χ2 = 0.500, P = 0.250). The correct rate of using transillumination was significantly higher than that of using auscultation χ2 = 7.563, P = 0.004). The sensitivity and specificity of the auscultation was 70.0% and 80.0%, that of transillumination technique was 96.7% and 93.3%, and P(ET)CO2 was 100%, respectively, for two groups. CONCLUSIONS P(ET)CO2 is the most reliable method for determining tube position, and it is superior to auscultation and transillumination. Transillumination technique is superior to auscultation, irrespective of anesthetists' experience, while the accuracy of auscultation showed an obvious relationship with the anesthetists' experience.

Abstract
Pathogenicity and immune responses were characterized in commercial broilers and layers challenged with very virulent infectious bursal disease virus (vvIBDV) reassortants (vvIBDV segment A + serotype 2 segment B and vvIBDV segment A + classic virulent segment B) at 7 days of age. In addition, functional immunosuppression was evaluated after challenge with infectious bronchitis virus (IBV) at 15 days of age. Layers showed higher levels and increased persistence of IBDV- and IBV-specific maternal antibodies than broilers at 1, 13, and 28 days of age. Cytokine gene expression was evaluated, after IBDV challenge, as an indicator of the innate immune function. Similar results were detected between the groups inoculated with vvIBDV reassortants. Interleukin-1β (IL-1β) in the bursa of layers demonstrated down-regulation at 1 day postinfection (DPI; 8 days of age), and no changes at 4 DPI (11 days of age) compared with controls. In broilers, IL-6 expression in the bursa was down-regulated 1 DPI (8 days of age) and up-regulated at 4 DPI (11 days of age). A significant lymphoid depletion was detected at 21 DPI (28 days of age) in broilers exposed to a reassortant of vvIBDV segment A and classic virulent IBDV segment B. Finally, reduced specific antibodies against IBV measured 13 days after challenge were detected in layer and broiler chickens inoculated with a reassortant serotype 2 IBDV in segment B, suggesting functional immunosuppression. These results provide evidence indicating that current IBDV vaccination of breeders does not completely protect progeny chickens from challenge with reassortant vvIBDV.

Abstract
Two hundred ninety isolates of Escherichia coli were investigated for the production of extended-spectrum beta-lactamases (ESBLs). Fourteen (4.8%) of the 290 strains were found to produce ESBLs. Each of the 14 strains produced one or two ESBLs, as follows: 10 strains produced TEM-52, 1 strain produced SHV-2a, 1 strain produced SHV-12, 1 strain produced a CMY-1-like enzyme, and 1 strain expressed SHV-2a and a CMY-1-like enzyme. Another two strains for which the MICs of ceftazidime and cefoxitin were high, were probable AmpC enzyme hyperproducers. Because of the high prevalence of TEM-52 in E. coli isolates, we further investigated the TEM-type ESBLs produced by Klebsiella pneumoniae in order to observe the distribution of TEM-52 enzymes among Enterobacteriaceae in Korea. All TEM enzymes produced by 12 strains of K. pneumoniae were identified as TEM-52. To evaluate the genetic relatedness among the organisms, ribotyping of TEM-52-producing E. coli and K. pneumoniae was performed. The ribotyping profiles of the organisms showed similar but clearly different patterns. In conclusion, TEM-52 is the most prevalent TEM-type ESBL in Korea.
