Abstract
In the medical field, the application of machine learning technology in the automatic diagnosis and monitoring of osteoporosis often faces challenges related to domain adaptation in drug therapy research. The existing neural networks used for the diagnosis of osteoporosis may experience a decrease in model performance when applied to new data domains due to changes in radiation dose and equipment. To address this issue, in this study, we propose a new method for multi domain diagnostic and quantitative computed tomography (QCT) images, called DeepmdQCT. This method adopts a domain invariant feature strategy and integrates a comprehensive attention mechanism to guide the fusion of global and local features, effectively improving the diagnostic performance of multi domain CT images. We conducted experimental evaluations on a self-created OQCT dataset, and the results showed that for dose domain images, the average accuracy reached 91%, while for device domain images, the accuracy reached 90.5%. our method successfully estimated bone density values, with a fit of 0.95 to the gold standard. Our method not only achieved high accuracy in CT images in the dose and equipment fields, but also successfully estimated key bone density values, which is crucial for evaluating the effectiveness of osteoporosis drug treatment. In addition, we validated the effectiveness of our architecture in feature extraction using three publicly available datasets. We also encourage the application of the DeepmdQCT method to a wider range of medical image analysis fields to improve the performance of multi-domain images.

Abstract
The structural morphology of mesenteric artery vessels is of significant importance for the diagnosis and treatment of colorectal cancer. However, developing automated vessel segmentation methods for this purpose remains challenging. Existing convolution-based segmentation methods have limitations in capturing long-range dependencies, while transformer-based models require large datasets, making them less suitable for tasks with limited training samples. Moreover, over-segmentation, mis-segmentation, and vessel discontinuity are common challenges in vessel segmentation tasks. To address these issues, we propose a parallel encoding architecture that combines transformers and convolutions to retain the advantages of both approaches. The model effectively learns position deviations and enhances robustness for small-scale datasets. Additionally, we introduce a vessel edge capture module to improve vessel continuity and topology. Extensive experimental results demonstrate the improved performance of our model, with Dice Similarity Coefficient and Average Hausdorff Distance scores of 81.64% and 7.7428, respectively.

Abstract
Supervisory control and data acquisition (SCADA) systems are widely utilized in power equipment for condition monitoring. For the collected data, there generally exists a problem-missing data of different types and patterns. This leads to the poor quality and utilization difficulties of the collected data. To address this problem, this paper customizes methodology that combines an asymmetric denoising autoencoder (ADAE) and moving average filter (MAF) to perform accurate missing data imputation. First, convolution and gated recurrent unit (GRU) are applied to the encoder of the ADAE, while the decoder still utilizes the fully connected layers to form an asymmetric network structure. The ADAE extracts the local periodic and temporal features from monitoring data and then decodes the features to realize the imputation of the multi-type missing. On this basis, according to the continuity of power data in the time domain, the MAF is utilized to fuse the prior knowledge of the neighborhood of missing data to secondarily optimize the imputed data. Case studies reveal that the developed method achieves greater accuracy compared to existing models. This paper adopts experiments under different scenarios to justify that the MAF-ADAE method applies to actual power equipment monitoring data imputation.

Abstract
Rehabilitation movement assessment often requires patients to wear expensive and inconvenient sensors or optical markers. To address this issue, we propose a non-contact and real-time approach using a lightweight pose detection algorithm-Sports Rehabilitation-Pose (SR-Pose), and a depth camera for accurate assessment of rehabilitation movement. Our approach utilizes an E-Shufflenet network to extract underlying features of the target, a RLE-Decoder module to directly regress the coordinate values of 16 key points, and a Weight Fusion Unit (WFU) module to output optimal human posture detection results. By combining the detected human pose information with depth information, we accurately calculate the angle between each joint in three-dimensional space. Furthermore, we apply the DTW algorithm to solve the distance measurement and matching problem of video sequences with different lengths in rehabilitation evaluation tasks. Experimental results show that our method can detect human joint nodes with an average detection speed of 14.32ms and an average detection accuracy for pose of 91.2%, demonstrating its computational efficiency and effectiveness for practical application. Our proposed approach provides a low-cost and user-friendly alternative to traditional sensor-based methods, making it a promising solution for rehabilitation movement assessment.

Abstract
BACKGROUND There is growing evidence that thyroid function affects bone metabolism and even fractures risk. However, little is known about the relationship between thyroid sensitivity and osteoporosis and fractures. Therefore, we explored the relationship between thyroid sensitivity-related indices and bone mineral density (BMD) and fractures in euthyroid US adults. METHODS In this cross-sectional study, 20,686 subjects from National Health and Nutrition Examination Survey (NHANES) data were extracted and analyzed during 2007 to 2010. A total of 3403 men and postmenopausal women aged 50 years or older with available data on diagnosis of osteoporosis and/or fragility fractures, bone mineral density (BMD) and thyroid function, were eligible. TSH index (TSHI), thyrotrophin T4/T3 resistance index (TT4RI/TT3RI), Thyroid feedback quantile-based index (TFQI), Parametric TFQI (PTFQI), free triiodothyronine to free thyroxine ratio (FT3/FT4), the secretory capacity of the thyroid gland (SPINA-GT) and the sum activity of peripheral deiodinases (SPINA-GD) were calculated. RESULTS FT3/FT4, SPINA-GD, FT4, TSHI, TT4RI, TFQI and PTFQIFT4 were significantly correlated with BMD (P < 0.001). Multiple linear regression analysis showed that FT3/FT4 and SPINA-GD was significantly positively associated with BMD, while FT4, TSHI, TT4RI, TFQI and PTFQIFT4 were negatively associated with BMD (P < 0.05 or P < 0.001). In logistic regression analysis, the odds ratio (OR) for osteoporosis of TSHI, TFQI and PTFQIFT4 were 1.314(1.076, 1.605), 1.743(1.327, 2.288) and 1.827(1.359, 2.455) respectively, and were 0.746(0.620, 0.898) for FT3/FT4 (P < 0.05). CONCLUSIONS In elderly euthyroid individuals, impaired sensitivity to thyroid hormones correlates to osteoporosis and fractures, independent of other conventional risk factors.

Abstract
BACKGROUND Palmoplantar pustulosis (PPP), a chronic, recurrent pustular dermatosis associated with erythema, scales, and sterile pustules on the palms and soles, is commonly encountered in dermatology clinics. Whether PPP is a variant of psoriasis or a distinct condition is still debated. Although biological agents have been successfully used to treat moderate-to-severe psoriasis, existing literature on PPP is limited to case reports or small case series. The lack of well-documented clinical studies makes it difficult to select the ideal treatment for this condition. This review aims to discuss the efficacy and safety of biological agents in PPP treatment based on randomized controlled trials with the hope of inspiring dermatologist clinicians to propose new therapeutic approaches. OBJECTIVES This review aims to obtain high-level evidence to assess the efficacy and safety of biological agents in the treatment of patients with PPP. METHODS We searched the PubMed, Embase, and Cochrane databases up to May 18, 2023, for high-quality randomized controlled trials that reported at least one adverse event after PPP treatment with biological agents in patients > 18 years of age. RevMan 5.3 software was used for the meta-analysis. RESULTS Nine trials involving 799 participants were included in the analysis. We used ppPASI 75 as the primary efficacy measure. Anti-IL-23 and anti-IL-17A agents afforded 4.14-fold and 1.95-fold better outcomes than placebo treatment at weeks 16 and 12, respectively (P-value = 0.009, RR = 4.14, 95% confidence interval [CI; 1.43-11.98]; P-value = 0.02, RR = 1.95, 95% CI [1.11-3.42]). Moreover, anti-IL-23 agents at a dose of 100 mg were more effective than at 200 mg, indicating that 100 mg may be the best dose for anti-IL-23 agents. Next, we investigated the safety of biological agents for PPP treatment. The incidence of total adverse events (AEs) was 1.25 times higher for biological agents than for controls, indicating a good safety profile (RR = 1.25, P-value < 0.00001, 95% CI [1.13, 1.37]). Additionally, we divided the common AEs into 16 categories and found that anti-IL-23 agents were more likely to induce infections. In conclusion, we evaluated safety and efficacy in a comprehensive comparison and found that anti-IL-23 agents conferred good clinical efficacy with a low incidence of AEs and could be recommended with caution. LIMITATIONS Only a few relevant, high-quality, randomized controlled trials were included in the study. CONCLUSION This study showed that biological agents can be used to treat patients with PPP with good efficacy; however, AEs cannot be ignored. Multi-center, high-quality clinical studies with large sample sizes are needed to further evaluate the effects and safety of biological agents in PPP treatment.

Abstract
ZrB2-SiC-Zr2Al4C5 multi-phase ceramics with uniform structure and high density were successfully prepared through the introduction of in situ synthesized Zr2Al4C5 into ZrB2-SiC ceramic via SPS at 1800 °C. A systematic analysis and discussion of the experimental results and proposed mechanisms were carried out to demonstrate the composition-dependent sintering properties, mechanical properties and oxidation behavior. The results showed that the in situ synthesized Zr2Al4C5 could be evenly distributed in the ZrB2-SiC ceramic matrix and inhibited the growth of ZrB2 grains, which played a positive role in the sintering densification of the composite ceramics. With increasing Zr2Al4C5 content, the Vickers hardness and Young's modulus of composite ceramics gradually decreased. The fracture toughness showed a trend that first increased and then decreased, and was increased by about 30% compared with ZrB2-SiC ceramics. The major phases resulting from the oxidation of samples were ZrO2, ZrSiO4, aluminosilicate and SiO2 glass. With increasing Zr2Al4C5 content, the oxidative weight showed a trend that first increased then decreased; the composite ceramic with 30 vol.% Zr2Al4C5 showed the smallest oxidative weight gain. We believe that the presence of Zr2Al4C5 results in the formation of Al2O3 during the oxidation process, subsequently resulting in a lowering of the viscosity of the glassy silica scale, which in turn intensifies the oxidation of the composite ceramics. This would also increase oxygen permeation through the scale, adversely affecting the oxidation resistance of the composites with high Zr2Al4C5 content.

Abstract
Case Individuals with Selective Immunoglobulin-A Deficiency (SIgAD) are often asymptomatic, and symptomatic SIgAD patients often have autoimmune comorbidities. A 48-year-old Han Chinese man presented with abdominal discomfort, hematochezia, and a large tumor in the anogenital region. The primary diagnosis of SIgAD was based on the patient's age, serum IgA concentration (0.067 g/L), and the evidence of chronic respiratory infection. No other immunoglobulin deficiency or evidence of immunosuppression was present. The primary diagnosis of giant condyloma acuminatum was based on human papilloma virus-6-positive laboratory results and histological characteristics. The tumor and adjacent skin lesions were resected. Hemoglobin concentration fell to 5.50 g/dL, and an emergency erythrocyte transfusion was performed. The body temperature increased to 39.8 ºC, suggesting a transfusion reaction, and 5 mg dexamethasone was administered intravenously. Hemoglobin concentration stabilized at 10.5 g/dL. The clinical signs and laboratory results indicated autoimmune hemolytic anemia, systemic lupus erythematosus, and Hashimoto's thyroiditis. Abdominal discomfort and hematochezia subsided. Though uncommon, the manifestation of multiple autoimmune comorbidities can occur in SIgAD patients. Further research is needed regarding the causes of SIgAD and the autoimmune disorders that often occur as comorbidities.

Abstract
OBJECTIVE To explore the improvements of high-fat intake on lung injury induced by Paragonimus proliferus infection in rats, and to preliminarily explore the mechanisms underlying the role of cytochrome P450 4A1 (CYP 4A1) in the improve ments. METHODS SD rats were randomly assigned into three groups, including the normal control group (n = 10), the infection and normal diet group (n = 12) and the infection and high-fat diet group (n = 12). Rats in the normal control group were fed with normal diet and without any other treatments, and animals in the infection and normal diet group were subcutaneously injected with 8 excysted metacercariae of P. proliferus via the abdominal wall, followed by feeding with normal diet, while rats in the infection and high-fat diet group were subcutaneously injected with 8 excysted metacercariae of P. proliferus via the abdominal wall, followed by feeding with high-fat diet. All rats were sacrificed 28 weeks post-infection, and serum samples and lung specimens were collected. Following hematoxylin-eosin (HE) staining of rat lung specimens, the rat lung injury was observed under an optical microscope, and alveolitis was evaluated using semi-quantitative scoring. Serum interleukin-1β (IL-1β) and tumor necrosis factor alpha (TNF-α) levels were measured using enzyme-linked immunosorbent assay (ELISA), and the cytochrome P450 4A1 (CYP 4A1) expression was quantified in rat lung specimens at transcriptional and translational levels using quantitative real-time PCR (qPCR) and Western blotting assays. RESULTS Alveolar wall thickening, edema and inflammatory cell infiltration were alleviated 28 weeks post-infection with P. proliferus in rats in the infection and high-fat diet group relative to the infection and normal diet group, and no alveolar consolidation was seen in the infection and high-fat diet group. The semi-quantitative score of alveolitis was significantly higher in the infection and normal diet group [(2.200 ± 0.289) points] than in the normal control group [(0.300 ± 0.083) points] and the infection and high-fat diet group [(1.300 ± 0.475) points] (both P values < 0.05), and higher serum IL-1β [(151.586 ± 20.492)] pg/mL and TNF-α levels [(180.207 ± 23.379) pg/mL] were detected in the infection and normal diet group than in the normal control group [IL-1β: (103.226 ± 3.366) pg/mL; TNF-α: (144.807 ± 1.348) pg/mL] and the infection and high-fat diet group [IL-1β: (110.131 ± 12.946) pg/mL; TNF-α: (131.764 ± 27.831) pg/mL] (all P values < 0.05). In addition, lower CYP 4A1 mRNA (3.00 ± 0.81) and protein expression (0.40 ± 0.02) was quantified in lung specimens in the infection and normal diet group than in the normal control group [(5.03 ± 2.05) and (0.84 ± 0.14)] and the infection and high-fat diet group [(11.19 ± 3.51) and (0.68 ± 0.18)] (all P values < 0.05). CONCLUSIONS High-fat intake may alleviate lung injuries caused by P. proliferus infection in rats through up-regulating CYP 4A1 expression in lung tissues at both translational and transcriptional levels.

Abstract
Background Selecting an appropriate and personalized Gn starting dose (GSD) is an essential procedure for determining the quality and quantity of oocytes in the controlled ovarian stimulation (COS) process of the in-vitro fertilization (IVF) treatment cycle. The current approach for determining the GSD is mainly based on the experience of a clinician, lacking unified and scientific standards. This study aims to establish a prediction model of GSD, based on which good COS outcomes can be achieved with the influencing factors comprehensively evaluated quantitatively. Material and methods We collected a total of 1555 patients undergoing the first oocytes retrieving cycle and conducted correlation analysis to find the significant factors related to the GSD. Two GSD models are built based on two popular machine learning approaches, and the one with better model performance is selected as the final model. Finally, clinical application and validation were conducted to verify the effectiveness of the proposed model. Results (1) Age, duration of infertility, type of infertility, body mass index (BMI), antral follicle count (AFC), basal follicle stimulating hormone (bFSH), estradiol (E2), luteinizing hormone (LH), anti-Müllerian hormone (AMH) and COS treatment regimen were closely related to the GSD (P < 0.05). (2) The selected model has good modeling performance in terms of both root mean square error (RMSE) (29.87 ~ 34.21) and regression coefficient R (0.947 ~ 0.953). (3) A comprehensive evaluation of influencing factors for GSD is conducted and shows that the top four most significant factors are age, AMH, AFC, and BMI. (4) The proposed GSD can approximate the actual value well in the clinical application, with the mean absolute error of only 11.26 units, and the recommended results can prompt the number of oocytes retrieved (NOR) close to the optimal number. Conclusion Modeling the GSD value with machine learning approaches is feasible and effective, and the proposed model has good clinical application for determining the GSD in the IVF treatment cycle.

Abstract
When trains pass through damaged switch rails, rail head damage will change wheel-rail contact states from rolling frictions to unsteady contacts, which will result in impact vibrations and threaten structural safeties. In addition, under approaching and moving away rolling contact excitations and complex wheel-rail contacts, the non-stationary vibrations make it difficult to extract and analyze impact vibrations. In view of the above problems, this paper proposes a variational-mode-decomposition (VMD)-spectral-subtraction (SS)-based impact vibration extraction method. Firstly, the time domain feature analysis method is applied to calculate the time moments that the wheels pass joints, and to correct vehicle velocities. This can help estimate and confine impact vibration distribution ranges. Then, the stationary intrinsic mode function (IMF) components of the impact vibration are decomposed and analyzed with the VMD method. Finally, impact vibrations are further filtered with the SS method. For rail head damage with different dimensions, under different velocity experiments, the frequency and amplitude features of the impact vibrations are analyzed. Experimental results show that, in low-velocity scenarios, the proposed VMD-SS-based method can extract impact vibrations, the frequency features are mainly concentrated in 3500-5000 Hz, and the frequency and peak-to-peak features increase with the increase in excitation velocities.

Abstract
OBJECTIVE Psoriasis is a common chronic inflammatory skin disease that is prone to recurrence, and the proinflammatory factor, cysteine-rich protein 61 (Cyr61), is important in its pathophysiology. Long-term clinical practice has shown that Sancao Formula (SC), a Chinese herbal compound, is effective in the treatment of psoriasis, but the precise mechanism remains unknown. In this study, we investigate the mechanism by which SC extract alleviates imiquimod (IMQ)-induced psoriasis. METHODS The expression of Cyr61 in psoriatic lesions and normal healthy skin was detected using immunohistochemical analysis to investigate the biological role of Cyr61 in models of psoriatic inflammation. A psoriatic mouse model was established by topical application of IMQ, and the effect of topical application of SC extract was evaluated using the psoriasis area and severity index (PASI) score, hematoxylin-eosin staining, and histopathological features of the skin. Next, a HaCaT cell inflammation model was established using interferon-γ (IFN-γ), and the effect of SC extract on the mRNA and protein levels of Cyr61 and intercellular cell adhesion molecule-1 (ICAM-1) was confirmed using Western blot and quantitative real-time polymerase chain reaction analyses. RESULTS Immunohistochemical staining showed that the expression of Cyr61 in psoriatic lesions was higher than that in normal skin samples (78.26% vs 41.18%, P < 0.05), and the number of Cyr61-positive cells in psoriatic lesions was also significantly higher than in normal skin (18.66 ± 2.51 vs 4.33 ± 1.52, P < 0.05). Treatment in mice with IMQ-induced psoriasis showed that SC extract could significantly improve the inflammatory phenotype, PASI score (10.875 ± 0.744 vs 3.875 ± 0.582, P < 0.05), and pathological features compared with those in IMQ model group; SC treatment was also associated with decreased levels of Cyr61 and ICAM-1. In the IFN-γ-induced inflammatory cell model, the mRNA and protein levels of Cyr61 and ICAM-1 were upregulated, while the SC extract downregulated the levels of Cyr61 and ICAM-1. CONCLUSION The results provide a theoretical basis for the involvement of Cyr61 in the pathogenesis of psoriasis, and suggest that SC should be used to target Cyr61 for the prevention of psoriasis recurrence.

Abstract
Reward signal reinforcement learning algorithms can be used to solve sequential learning problems. However, in practice, they still suffer from the problem of reward imbalance, which limits their use in many contexts. To solve this unbalanced reward problem, in this paper, we propose a novel model-based reinforcement learning algorithm called the expected n-step value iteration (EnVI). Unlike traditional model-based reinforcement learning algorithms, the proposed method uses a new return function that changes the discount of future rewards while reducing the influence of the current reward. We evaluated the performance of the proposed algorithm on a Treasure-Hunting game and a Hill-Walking game. The results demonstrate that the proposed algorithm can reduce the negative impact of unbalanced rewards and greatly improve the performance of traditional reinforcement learning algorithms.

Abstract
Background Acute gouty arthritis (GA) is the main clinical manifestation and the most common initial symptom of gout. The treatment of acute GA involves the use of colchicine, non-steroidal anti-inflammatory drugs, and corticosteroids. Because of the side effects of these drugs, their clinical applications are limited. The use of traditional Chinese medicine for the treatment of acute GA has unique advantages. The aim of this trial is to clarify the treatment efficacy, safety, and recurrence control efficacy of Huzhang granules (HZG) in patients with GA showing dampness-heat syndrome. Methods/design This double-blind, randomized, controlled trial was planned to be conducted between July 1, 2020, and December 31, 2022. A sample size of 267 participants (89 per group) with GA will be randomly assigned to three treatment groups in the ratio of 1:1:1: HZG, etoricoxib, and placebo groups. The study duration is 13 days, including a 1-day screening period, 5-day intervention period, and 1-week follow-up period. The primary outcome is analgesic effectiveness, assessed as pain in the worst-affected joint, which will be measured using the visual analog scale. Secondary outcomes include the patient’s assessment of pain in the primary study joint, patient’s global assessment of response to therapy, investigator’s global assessment of response to therapy, investigator’s assessment of tenderness and swelling of the study joint, and TCM syndromes. Furthermore, the number, nature, and severity of adverse events will be recorded. Discussion This study will provide evidence regarding the clinical efficacy and safety of Chinese medicine treatment for acute gouty arthritis. This study will provide noteworthy findings. Trial registration ClinicalTrials.gov NCT04462666. Registered on July 05, 2020 (first version).

Abstract
Objective: To improve the diagnostic accuracy of pulmonary artery sarcoma, and to distinguish it from central chronic pulmonary thromboembolism using CT scans. Methods: In this retrospective study, two groups of pulmonary artery sarcoma (PAS group) and central chronic pulmonary thromboembolism (central CPTE group) confirmed by pathology at our hospital between August 2009 and July 2019 were enrolled, clinical features and pre-operative CT pulmonary artery manifestation were collected, and the key points of differential diagnosis were summarized. Results: The study was composed of 13 cases in the PAS group including 10 males (76.9%), with an average age of (45.4±15.5) years. There were 19 patients in the central CPTE group including 14 males (73.7%), with an average age of (38.6±14.1) years. There were no significant differences in gender and age between the two groups. Deep venous thrombosis in the lower extremities was significantly higher in the central CPTE group than in the PAS group (7/19 vs. 0/13, P=0.025), and the N-terminal pro-brain natriuretic peptide value was higher in the central CPTE group than in the PAS group [674.50(261.70-1 977.70) vs. 66.00(28.10-505.50),P=0.001]. In CT pulmonary angiography, the involvement of the main pulmonary artery, and the proximal lesion showing an acute angle to the pulmonary artery wall were more common in the PAS group [11(84.6%) vs. 5(26.3%), P=0.003; 11(84.6%) vs. 2(10.5%), P<0.001, respectively]. The swelling index of the main pulmonary and the left/right main pulmonary arteries in the PAS group were significantly higher, as well as the dilatation in the lobar and segmental pulmonary arteries [1.19±0.17 vs. 0.99±0.19,P=0.006, 10(76.9%) vs. 2(10.5%), P<0.001, respectively]. The right ventricular transverse diameter/left ventricular transverse diameter (RVd/LVd) and pulmonary artery diameter/ascending aortic diameter ratio (Pad/Aod) were significantly lower in PAS group than those in the central CPTE group (0.97±0.19 vs. 1.23±0.35,P=0.020; 0.98±0.25 vs. 1.15±0.20,P=0.039). Conclusions: In CT pulmonary angiography, filling defects involving the main pulmonary artery and showing expansive growth were highly suggestive of pulmonary artery sarcoma. The history of deep venous thrombosis of the lower extremities was helpful for the diagnosis of chronic pulmonary embolism.

Abstract
Background
The pathophysiological alterations in response to shunt correction in patients with pulmonary arterial hypertension associated with congenital heart disease (CHD-PAH) is still not clear.
Purpose
To explore the dynamic plasma metabolite profiling and its relationship with clinical characteristics in patients with CHD-PAH during the perioperative period of defect repair.
Methods
Plasma samples from 13 patients with CHD-PAH were harvested at four time points: before cardiopulmonary bypass (CPB) after anesthesia (Pre), immediately after CPB (T0), 24 h (T24), and 48 h (T48) after defect repair. The untargeted metabolomics strategy based on UPLC Q-TOF MS was used to detect the metabolites. Clinical measures were recorded at indicated time points.
Results
The sample distribution at four time points was well separated (Figure 1A, B). 193 metabolites were distinguished at different time points according to Variable Important in Projection (VIP) score (Figure 1C), enriched in pathways such as carnitine synthesis, phospholipid biosynthesis and oxidation of branched chain fatty acids (Figure 2A). 17 metabolites alterations were significantly correlated with gradients in mean pulmonary arterial pressure (mPAP) at T48 versus Pre, indicative of the response to defect correction (Figure 2B). Intriguingly, 4 out of the 17 (23.5%) metabolites including propionylcarnitine, butenylcarnitine, isobutyryl-L-carnitine and hexanoylcarnitine were enriched in oxidation of branched chain fatty acids. They were increased at both T24 and T48 (all P<0.05 except propionylcarnitine with P<0.05 at T24) (Figure 2C).
Conclusions
This is the first study to show the altered metabolic profiles of CHD-PAH patients in perioperative period of defect repair. Metabolites that respond to shunt correction could be a suitable non-invasive marker and would be of great value in disease monitoring and evaluating future therapeutic interventions.

Abstract
Background: Our earlier meta-analysis showed that the correlation between psoriasis and hyperuricemia might be region-dependent and that hyperuricemia was more common in patients with psoriasis in Western Europe. However, no further analysis could be conducted owing to the scarcity of data. Objective: Our study aimed to further explore the association between psoriasis and hyperuricemia. Methods: Six databases (PubMed, Embase, the Cochrane Central Register of Controlled Trials, the China National Knowledge Infrastructure database, the Chinese Scientific Journals Full Text Database, and the Wanfang Data Knowledge Service Platform) were searched for studies published between January 1980 and February 2021. Results: The search strategy yielded 291 relevant studies, of which 27 observational studies were included in this analysis. Serum uric acid (SUA) levels (mean difference [MD] 0.99, 95% confidence interval [CI] 0.48-1.49, P = 0.0001) and hyperuricemia frequency (odds ratio [OR] 5.39, 95% CI 1.88-15.40, P = 0.002) were higher in the psoriasis group than in the control group, and the subgroup differences were significant. In addition, SUA levels were significantly higher in patients with moderate to severe psoriasis from European and American countries (MD 0.89, 95% CI 0.18-1.60, P = 0.01) and Southeast Asia (MD 1.79, 95% CI 0.55-3.02, P = 0.004), while no significant differences were found between the Middle East subgroup (MD 0.63, 95% CI -0.33 to 1.59, P = 0.20). Similar results were obtained from the meta-analysis of SUA levels in patients with metabolic syndrome, obesity, or a special type of psoriasis (such as arthritic or erythrodermic psoriasis). Conclusions: Our meta-analysis study provides extended data regarding the correlation between psoriasis and hyperuricemia and the differences in SUA levels between psoriasis patients and controls in Southeast Asia, the Middle East, and European and American countries. Patients with moderate to severe psoriasis in European and American countries and Southeast Asia or those with metabolic syndrome and obesity were more likely to have higher uric acid levels.

Abstract
OBJECTIVES The objectives of this study were to explore the effect of Osthole (Ost) on apoptosis in pulmonary artery smooth muscle cells (PASMCs) and investigate the potential mechanism of this effect. METHODS Rats were injected subcutaneously with monocrotaline (MCT) to establish a PAH model, and Ost were intragastrically administrated from day 1 to day 35. After 35 days administration, the mean pulmonary artery pressure and lung weight index were measured. HE and TUNEL staining were used to observe the morphology of pulmonary artery and the apoptosis of PASMCs. In addition, the apoptosis of PASMCs were detected by flow cytometry in cultured PASMCs. The proteins of Bax and Bcl-2, and the levels of p-ASK1 and cleaved caspase 3 were measured by Western blot. KEY FINDINGS Ost decreased the mean pulmonary artery pressure and lung weight index in MCT-induced rats, and promoted apoptosis in PASMCs in MCT-induced rats and PDGF-BB stimulated PASMCs. Ost increased the ratio of Bax/Bcl-2 and the levels of p-ASK1, cleaved caspase 3 in MCT-induced rats and PDGF-BB stimulated PASMCs. CONCLUSION Ost promoted apoptosis in PASMCs in vivo and in vitro, and the mechanism may be associated with upregulation of ASK1 and the Bax/Bcl-2-caspase 3 signalling pathway.

Abstract
Objective: To develop and validate the health-related quality of life (HRQOL) questionnaire for adult patients with anisometropic amblyopia. Methods: Cross-sectional study. A total of 170 adult patients with anisometropic amblyopia, 100 adult patients with other eye diseases and 80 healthy adults with normal vision were recruited at the First Affiliated Hospital of Nanjing Medical University, and 20 healthy adults with normal vision were recruited at Qinhuai Medical District of Easter Theater General Hospital of PLA from December 2019 to February 2020. Individual interviews of 30 adult patients with anisometropic amblyopia generated 80 questionnaire items. For item reduction, 40 adult patients with anisometropic amblyopia were asked to complete the 80-item questionnaire and responses were analyzed. Then factor analyses were performed to identify prominent factors (subscales). The reliability of the questionnaire was evaluated by Cronbach's α coefficient. The overall and sub-scale scores were the average scores of all included items, ranging from 0 (worst HRQOL) to 100 (best HRQOL). The final 20-item questionnaire was administered to additional 100 adult patients with anisometropic amblyopia, 100 adult patients with other eye diseases and 100 visually normal adults. Mean overall and subscale scores were compared across groups using one-way analysis of variance. Results: The final adult anisometropic amblyopia questionnaire (AAAQ) consisted of a function subscale and a psychosocial subscale, each containing 10 items. The Cronbach's α coefficients of the overall, function subscale and psychosocial subscale were 0.88, 0.78 and 0.78. There were 55 males and 45 females in 100 adult anisometropic amblyopia patients, with a median age of 26 years (range, 18 to 43 years). The age and gender distribution were matched with 100 adult patients with other eye diseases and 100 healthy adults with normal vision (all P>0.05). The mean overall score (28.63±9.18), function subscale score (27.69±9.88) and psychosocial subscale score (29.53±9.90) for adult patients with anisometropic amblyopia were significantly lower compared to adult patients with other eye diseases (71.28±8.14, P<0.01; 65.56±7.81, P<0.01; 76.85±10.76, P<0.01) and visually normal adults (84.54±9.13, P<0.01; 81.70±9.27, P<0.01; 87.38±10.06, P<0.01). Conclusion: The AAAQ meets the requirements for validity and reliability of a HRQOL questionnaire, and can be used to assess the HRQOL of adult patients with anisometropic amblyopia.

Abstract
OBJECTIVE The hyperglycemic environment of diabetes promotes chondrocyte (CH) apoptosis and is closely related to the occurrence and development of osteoarthritis (OA). This present study aimed to elucidate the relation between the cytoskeleton and the caspase-3 expression of human CHs in high glucose in vitro. PATIENTS AND METHODS We used different concentrations of glucose medium to test the effect of glucose on the CHs viability. Cytochalasin D and colchicine were used to prevent the aggregation of F-actin and β-tubulin. Besides, Z-DEVD-FMK (ZDF) or Apoptosis Activator 2 was used to inhibit or activate the caspase-3 expression. The intensity of F-actin and β-tubulin, cell viability, apoptosis, and caspase-3 expression were analyzed. RESULTS Three days of treatment of 30 mM or 40 mM glucose significantly decreased the CHs viability compared to the 10 mM but increased the caspase-3, apoptosis, collagen, and the aggregation of the F-actin and β-tubulin. However, the cytochalasin D and colchicine partly rejected the high-glucose induced caspase-3 upregulation, apoptosis, and CHs disability. Besides, these two anti-aggregation drugs also suppressed the Apoptosis Activator 2 induced caspase-3 upregulation and apoptosis. Furthermore, the application of ZDF could only prevent the F-actin aggregation, but not the β-tubulin. CONCLUSIONS Long-term high glucose triggers the caspase-3 expression and leads to the CH apoptosis involving cytoskeleton aggregation. Inhibition of cytoskeleton aggregation through the F-actin or β-tubulin could alleviate the high glucose-induced caspase-3 upregulation.

Abstract
BACKGROUND A previous study indicated that gut microbiota changed notably in Graves' orbitopathy (GO) patients as compared to controls. However, the characteristics of intestinal bacteria in Graves' disease (GD) and GO are unclear. OBJECTIVE The present study aimed to identify specific intestinal bacteria of GD and GO, respectively. METHODS The gut microbial communities of the fecal samples of 30 GD patients without GO, 33 GO subjects, and 32 healthy subjects were analyzed and compared by 16S rRNA gene sequencing. RESULTS At the phylum level, the proportion of Deinococcus-Thermus and Chloroflexi was decreased significantly in GO patients as compared to GD. At the genus level, the proportion of Subdoligranulum and Bilophila was increased while that of Blautia, Anaerostipes, Dorea, Butyricicoccus, Romboutsia, Fusicatenibacter, unidentified_ Lachnospiraceae, unidentified_Clostridiales, Collineslla, Intestinibacter, and Phascolarctobacterium was decreased in the GO group as compared to the GD group. Random forest analysis was used for the identification of specific intestinal microbiota, and Deinococcus-Thermus, Cyanobacteria and Chloroflexi were ranked in the top ten according to their contributions to sample classification. Moreover, compared to the control, there were multiple gut bacterial enrichment metabolic pathways in GO and GD patients, including nucleotide metabolism, enzyme family, and energy metabolism. Compared to GO, the only enrichment metabolic pathway found in GD was the viral protein family. CONCLUSIONS This study highlighted the significant differences in the intestinal microbiota and predictive functions of GD with GO, thereby providing new insights into the role of the gut bacteria that might contribute to the development of GO in GD patients.

Abstract
β-Thujaplicin possess a variety of biological activities. The use of modified biological nanoparticles (NPs) to develop novel anti-influenza drugs has increased in recent years. Selenium nanoparticles (SeNPs) with antiviral activity have attracted increasing attention for biomedical intervention. Functionalized SeNPs by β-thujaplicin (Se@TP) surface modified with superior antiviral activity were synthesized in this study. Compared to a virus group (43%), when treated with Se@TP (88%), the cell survival rate of MDCK cells was 45% higher. Se@TP could inhibit H1N1 from infecting Madin-Darby canine kidney (MDCK) cells and block chromatin condensation and DNA fragmentation. Se@TP obviously prevented MDCK cells from generating reactive oxygen species. Furthermore, Se@TP prevents lung injury in H1N1-infected mice through eosin staining and hematoxylin in vivo. Mechanistic investigation revealed that Se@TP inhibited H1N1 influenza virus from infecting MDCK cells through induction of apoptosis via suppressing AKT and p53 signaling pathways through immunohistochemical assay. Our results suggest that β-thujaplicin-modified SeNPs as carriers are an efficient way to achieve an antiviral pharmaceutical candidate for H1N1 influenza.

Abstract
Abstract
Background
Pulmonary arterial hypertension (PAH) can occur in families with hereditary hemorrhagic telangiectasia (HHT), but it has not been well-characterized.
Purpose
This study sought to characterize the genetic defects, clinical and hemodynamic features, and outcomes of PAH patients in HHT families.
Methods
All HHT families with at least one case of PAH investigated in our center from January 2006 to December 2018 were enrolled in the study. We did whole-exome sequencing (WES) or whole-genome sequencing (WGS) to every proband and available family members. The clinical data, hemodynamic features and outcomes of PAH patients were reviewed.
Results
A total of 64 PAH patients in 57 families were enrolled. Only 7 (12.3%) families had more than one case of PAH. Activin-receptor-like kinase 1 (ALK-1) mutation and Endoglin (ENG) mutation were confirmed in 49 (86.0%) and 3 (5.3%) families and other 5 (8.8%) had no known mutation associated with HHT or PAH. The median age when PAH diagnosis was 22 [9–33] years and female was dominant (70.3%). Most patients (84.4%) had signs of HHT and anemia was recorded in 14 (21.9%) patients. Remarkably, these patients showed severely compromised hemodynamics with elevated mean pulmonary artery pressure (62 [51, 77] mm Hg) and pulmonary vascular resistance index (17.0 [11.2, 22.8] Wood units*m2). Also, impaired exercise capacity was recorded at diagnosis with decreased six-minute walking distance (410 [342–485] meters) and over half (54.7%) were in WHO functional class III or IV. The 1-, 3-, 5- and 10-year transplantation-free survival for the overall PAH patients was 95.0%, 75.9%, 67.1% and 36.4%, respectively. Anemia (HR: 4.24 [1.32–13.65], p=0.016) and CI <2.5 l/min/m2 (HR: 4.39 [1.20–16.09], p=0.026) were independent risk factors for mortality.
Conclusions
PAH in HHT families is a devastating condition characterized by a young age at PAH diagnosis, poor clinical status and outcomes mainly underlying ALK-1 mutation, which emphasizes the importance to pay attention to this group of patients.

Abstract
Ultraviolet B (UVB) exposure is a core factor that leads to skin disease or carcinogenesis through the insufficient repair of DNA lesions. UVB-induced DNA lesions are mainly removed by the nucleotide excision repair (NER) mechanism. The expression of histone deacetylase 4 (HDAC4) is altered in the skin upon UVB exposure, indicating its possible implication in UVB-induced DNA lesions repair. Here, we investigated the role of HDAC4 in the NER removal of the main classes of UVB-induced DNA lesions consisting of cyclobutane pyrimidine dimers and pyrimidine (6-4) pyrimidone photoproducts (6-4PPs). We found that UVB irradiation increased HDAC4 expression at both the mRNA and protein levels. HDAC4 interacted with NER factor XPC, which played an important role in effectively removing the UVB-induced DNA lesions. This study provides an understanding of the HDAC4 function in DNA repair, which will allow the development of efficient strategies to protect the skin from UVR-induced diseases.

Abstract
OBJECTIVE To elucidate the protective role of resveratrol (RSV) in myocardial apoptosis induced by ischemia-reperfusion injury in rats with acute myocardial infarction (AMI), and to explore its underlying mechanism. MATERIALS AND METHODS The AMI rat model was successfully established by ligation of the left anterior descending coronary artery. Rat cardiomyocytes were isolated and cultured. Cells were divided into four groups, including: control group (no specific treatment), AMI group (acute ischemia-reperfusion treatment), AMI+RSV group (RSV pretreatment for 24 h before acute ischemia-reperfusion) and AMI+ RSV+LY group (RSV pretreatment combined with 40 μmol/L phosphatidylinositide 3-kinases (PI3K) pathway inhibitor LY294002 for 24 h before acute ischemia-reperfusion). Morphology of apoptotic cardiomyocytes in each group was observed by Hoechst staining. The proliferation, apoptosis and cell cycle progression of cardiomyocytes were determined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay, terminal dexynucleotidyl transferase(TdT)-mediated dUTP nick end labeling (TUNEL) assay and flow cytometry, respectively. Finally, the protein levels of genes relative to PI3K/Akt/eNOS pathway were detected by Western blot. RESULTS Hoechst staining showed a large number of necrotic cells, cell retraction, enhanced refractive index and enlarged cell gap in AMI group. A small number of necrotic cells were found in AMI+RSV group, which was significantly fewer than that of AMI group. Meanwhile, remaining cells presented normal morphology. However, a great number of necrotic cells were observed in AMI+RSV+LY group, which was obviously more than that of AMI+RSV group. Compared with control group, cells in AMI group showed significantly decreased proliferative rate, increased early phase, late phase and total one of apoptosis. In AMI group, the ratio of G0/G1 phase was remarkably increased, whereas those of S and G2/M phases were decreased. Moreover, the expression levels of phosphorylated Akt (p-Akt) and phosphorylated e-NOS (p-eNOS) were significantly downregulated in AMI group. In AMI+RSV group, cell apoptosis, cell cycle progression and levels of p-Akt and p-eNOS showed the opposite trends as those of AMI group. However, LY294002 pretreatment reversed the protective role of RSV in cellular behaviors of cardiomyocytes. CONCLUSIONS RSV protects cardiomyocyte apoptosis from ischemia-reperfusion injury through regulating phosphorylation levels of proteins relative to PI3K/Akt/e-NOS pathway.

Abstract
Small interfering RNA (siRNA) exhibits great potential as a novel therapeutic option due to its highly sequence-specific ability to silence genes. However, efficient and safe delivery carriers are required for developing novel therapeutic paradigms. Thus, the successful development of efficient delivery platforms for siRNA is a crucial issue for the development of siRNA-based drugs in cancer treatments. In this study, biocompatible selenium nanoparticles (SeNPs) were loaded with RGDfC peptide to fabricate tumor-targeting gene delivery vehicle RGDfC-SeNPs. Subsequently, RGDfC-SeNPs were loaded with Derlin1-siRNA to fabricate RGDfC-Se@siRNA, which are functionalized selenium nanoparticles. RGDfC-Se@siRNA showed greater uptake in HeLa cervical cancer cells in comparison with that in human umbilical vein endothelial cells (HUVECs), verifying the RGDfC-mediated specific uptake of RGDfC-Se@siRNA. RGDfC-Se@siRNA was capable of entering HeLa cells via clathrin-associated endocytosis, and showed faster siRNA release in a cancer cell microenvironment in comparison with a normal physiological environment. qPCR and western blotting assays both indicated that RGDfC-Se@siRNA exhibited an obvious gene silencing efficacy in HeLa cells. RGDfC-Se@siRNA suppressed the invasion, migration and the proliferation of HeLa cells, and triggered HeLa cell apoptosis. Moreover, RGDfC-Se@siRNA induced the disruption of mitochondrial membrane potentials. Meanwhile, RGDfC-Se@siRNA enhanced the generation of reactive oxygen species (ROS) in HeLa cell, suggesting that mitochondrial dysfunction mediated by ROS might play a significant role in RGDfC-Se@siRNA-induced apoptosis. Interestingly, RGDfC-SeNPs@siRNA exhibited significant antitumor activity in a HeLa tumor-bearing mouse model. Additionally, RGDfC-SeNPs@siRNA is nontoxic to main organ of mouse. The above results indicate that RGDfC-Se@siRNA provides a promising potential for cervical cancer therapy.

Abstract
OBJECTIVE Gouty arthritis (GA) is a noninfectious inflammatory disease characterized by self-limited and severe pain. Huzhang Tongfeng granule is one of the most effective traditional Chinese medicines in the treatment of acute GA. However, its effects on the inflammatory factors in the process of acute gout inflammation remain unknown. In the present study, we aimed to evaluate the effect of Huzhang Tongfeng granule on the expressions of Cyr61 and related inflammatory factors in both experimental gout models in vivo and in vitro. METHODS Huzhang Tongfeng granule was provided by the pharmaceutical preparation room of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine. The expressions of Cyr61, IL-1β, TNF-α, and IL-6 in monosodium urate- (MSU-) induced rat models and fibroblast-like synoviocytes (FLSs) were determined by RT-PCR, Western blotting analysis, ELISA, immunohistochemistry, and hematoxylin and eosin staining. RESULTS Huzhang Tongfeng granule could downregulate the expressions of IL-1β, TNF-α, and IL-6 to some extent by inhibiting the expression of Cyr61. CONCLUSIONS Collectively, our findings indicated that Cyr61 was highly expressed in rat models of gout. By inhibiting the expression of Cyr61, Huzhang Tongfeng granule could partially attenuate the inflammation induced by MSU crystal.

Abstract
Leaf venations have elements with relatively lower elasticity than other leaf tissue components, which are thought to contribute to leaf biomechanics. A better mechanistic understanding of relationships between vein traits and leaf mechanical properties is essential for ecologically relevant interpretation of leaf structural variations. We investigated 13 major (first to third order) and minor (>third order) vein traits, six leaf mechanical properties and other structural traits across 58 woody species from a subtropical forest to elucidate how vein traits contribute to leaf biomechanics. Across species, vein dry mass density (ρv ), total vein dry mass per leaf area (VMA) and minor vein diameter (VDmin ), but not the lower-order vein density (VLA1•2 ), were positively correlated with leaf force to punch (Fp ) and force to tear (Ft ). Structural equation models showed that ρv and VDmin not only contribute to leaf mechanical properties directly (direct pathway), but also had impacts on leaf biomechanics by influencing leaf thickness and leaf dry mass per area (indirect pathway). Our study demonstrated that vein dry mass density and minor vein diameter are the key vein properties for leaf biomechanics. We also suggest that the mechanical characteristics of venations are potential factors influencing leaf mechanical resistance, structure and leaf economics spectrum.

Abstract
Studies have proved the role of GAS5 in the development of different cancers. This study was undertaken to investigate the role and explore therapeutic implications of GAS5 in human cervical cancer. The results showed that GAS5 was significantly (p < 0.05) downregulated in human cervical cancer tissues. The results also showed that cervical cancer progresses with the suppression of GAS5 expression levels. Additionally, the expression of GAS5 was also significantly (p < 0.05) downregulated in human cervical cancer cell lines. Nonetheless, overexpression of GAS5 caused a remarkable decrease in the proliferation of C33A and HeLa cervical cancer cells. The decrease in the proliferation rate was attributed to the induction of apoptosis of C33A and HeLa cells which was accompanied with upregulation of Bax and suppression of Bcl-2. Additionally, GAS5 overexpression also promoted the arrest of C33A and HeLa cells at the G2/M check point of cell cycle via suppression of cyclin B1 and CDK1 expression. The transwell assays showed that GAS5 overexpression significantly (p < 0.05) inhibited the migration and invasion of the C33A and HeLa cervical cancer cells. The bioinformatics analysis as well as the dual luciferase assay showed GAS5 acts as a target of miR-135a. Interestingly, the expression of miR-135a was upregulated in the human cervical cancer cells and its suppression exerted growth inhibitory effects on the C33A and HeLa cells. However, silencing of GAS5 could nullify the effects of miR-135a suppression on the proliferation of C33A and HeLa cells. Taken together, the results of this study point towards the therapeutic implications of GAS5 in the treatment of cervical cancer.

Abstract
Enterovirus 71 (EV71) which commonly caused the hand-foot-mouth disease (HFMD) has become one of public health challenges worldwide. However, no effective vaccines or drugs for this disease has been developed. Thus, there is an urgent need to find a new strategy for treating the EV71 infection. Oseltamivir (OT) is an effective antiviral agent, but continuous use of oseltamivir leads to a diminished therapeutic effect in the clinic. In order to improve the antiviral activity of oseltamivir, oseltamivir was loaded onto surfaces of selenium nanoparticles (SeNPs) to fabricate a functionalized antiviral nanoparticles SeNPs@OT. The size of SeNPs@OT was tested by TEM and dynamic light scattering. The chemical structure and elemental composition of SeNPs@OT were analyzed by FT-IR and EDX, respectively. SeNPs@OT exhibited good stability and effective drug release in serum and PBS. SeNPs@OT efficiently entered into human astrocyte U251 cells (host cells) via clathrin-associated endocytosis and inhibited EV71 proliferation, which could protect EV71-infected U251 cells from apoptosis through mitochondrial pathway. Furthermore, SeNPs@OT inhibited EV71 activity probably by reducing the generation of reactive oxygen species in EV71-infected U251 cells. Interestingly, SeNPs obviously enhanced antiviral activity of oseltamivir in the anti-EV71 cell model. Taken together, SeNPs@OT is a promising antiviral drug candidate for EV71 infection.

Abstract
Galactose-modified selenium nanoparticles (GA-SeNPs) loading with doxorubicin (DOX) for hepatocellular carcinoma (HCC) therapy was investigated in this paper. Selenium nanoparticles (SeNPs) were modified with galactose as tumor targeting moiety to fabricate tumor-targeted delivery carrier GA-SeNPs, then doxorubicin was loaded onto the surface of GA-SeNPs for improving antitumor efficacy of DOX in HCC therapy. Chemical structure characterization of GA-Se@DOX showed that DOX was successfully loaded to the surface of GA-SeNPs to prepare functionalized antitumor drug delivery system GA-Se@DOX. GA-Se@DOX exhibited effective cellular uptake in HepG2 cells and entered HepG2 cells mainly by clathrin-mediated endocytosis pathway. GA-Se@DOX showed significant activity to induce the apoptosis of HepG2 cells in vitro. The western blotting result indicated that GA-Se@DOX induced HepG2 cells apoptosis via activating caspase signaling and Bcl-2 family proteins. Moreover, active targeting delivery system GA-Se@DOX exhibited excellent antitumor efficacy in vivo in comparison with passive targeting delivery system Se@DOX. Histology analysis showed that GA-Se@DOX exhibited no obvious damage to major organs including heart, liver, spleen, lung, and kidney under the experimental condition. Taken together, GA-Se@DOX may be one novel promising nanoscale drug candidate for HCC therapy.

Abstract
Protein kinase D (PKD) has been implicated in cancer cell survival, proliferation, migration and angiogenesis. However, it is still unknown whether PKD regulates cell proliferation through lipid metabolism in cancer cells. Here we report a novel function of PKD3, a member of PKD family, in regulating of prostate cancer cell proliferation by modulation of SREBP1-mediated de novo lipogenesis. We show that silencing of PKD3 significantly reduces lipid content and expression of the lipogenic genes encoding FASN and ATP-citrate lyase (ACLY). Moreover, endogenous PKD3 interacts with sterol regulatory element binding protein 1(SREBP1) in DU145 cells. Interestingly, PKD3 silencing decreases not only the level of matured-SREBP1 (68KD) but also the binding of SREBP1 to the promoter of fasn gene. In addition, overexpression of SREBP1 reverses the suppression of cell growth caused by PKD3 depletion. Finally, immune-histochemical staining indicate that PKD3 expression is positively correlated with expression of FASN and SREBP1 in prostate cancers. Taken together, these data suggest that targeting PKD3-mediated de novo lipogenesis may be a potential therapeutic approach to block prostate cancer progression.

Abstract
BACKGROUND The intestinal microbiota was linked to autoimmune diseases. Graves' orbitopathy (GO) is an autoimmune disease that is usually associated with Graves' disease. However, information on the microbiome of GO patients is yet lacking. OBJECTIVES To investigate whether GO patients differ from healthy controls in the fecal microbiota. DESIGN A cross-sectional study. SETTING 33 patients with severe and active GO and 32 healthy controls of Han nationality were enrolled between March 2017 and March 2018. METHODS The Gut microbial communities of the fecal samples of GO patients and healthy controls were analyzed and compared by 16S rRNA gene sequencing. RESULTS Community diversity (Simpson and Shannon) was significantly reduced in fecal samples from patients with GO as compared to controls (p < 0.05). The similarity observed while assessing the community diversity (PCoA) proposed that the microbiota of patients with GO differ significantly from those of controls (p < 0.05). At the phyla levels, the proportion of Bacteroidetes increased significantly in patients with GO (p < 0.05), while at the genus and species levels, significant differences were observed in the bacterial profiles between the two groups (p < 0.05). LIMITATIONS Single-centered study design and limited fecal samples. CONCLUSIONS The present study indicated distinctive features of the gut microbiota in GO patients. The study provided evidence for further exploration in the field of intestinal microbiota with respect to the diagnosis and treatment of GO patients by modifying the microbiota profile.

Abstract
As one of the major causative agents of hand, foot and mouth disease (HFMD), enterovirus 71 (EV71) is a small, non-enveloped positive stranded RNA virus. Children suffering EV71 infection may cause severe symptoms including neurological complications, pulmonary edema and aseptic meningitis. EV71 is a neurotropic virus and it can cause the damage of nervous cells, cytokine storm and toxic substance. Identifying the factors that mediate viral binding or entry to host cells is important to uncover the mechanisms which viruses utilize to cause diseases in human body. Heat shock protein 70 (HSP70) is induced during virus infection and facilitates proper protein folding during viral propagation. The role that HSP70 plays during EV71 infection is still unclear. In this study, siRNA interference technique and transgenic technique were used to investigate the interaction between HSP70 and EV71 virus. The result demonstrated that the cell surface HSP70 is not essential for EV71 infection but helps the initial binding of virus to host cells and that multiple receptors are involved during EV71 infection. In addition, HSP70 was upregulated in human neuroblastoma cells (SK-N-SH) infected with EV71.

Abstract
This paper aims to investigate the hydrological response of a large-scale (8973 km2) mountainous watershed to different rainstorm spatial patterns and reforestation. Based on 32 years of observations, measurements of 184 rainstorm events and 125 sediment-producing events with complete hydrographs were analyzed. The K-means clustering method was used to classify the spatial patterns of rainstorm events in accordance with their event-based spatial rainfall characteristics. The 184 rainstorm events were classified into four spatial patterns, among which the spatial features differ significantly: (I) Spatial Pattern I (SPI) includes rainstorms with a low amount of cumulative areal rainfall (27.4 mm), the highest spatial variability (0.986), and the highest frequency; (II) Spatial Pattern II (SPII) includes rainstorms of high spatial variability (0.759) and the largest amount of local maximum daily rainfall (106.8 mm); (III) Spatial Pattern III (SPIII) includes rainstorms with a medium amount of cumulative areal rainfall (58.7 mm) and low spatial variability (0.362); and (IV) Spatial Pattern IV (SPIV) includes rainstorms with the largest amount of cumulative areal rainfall (117.2 mm) and the lowest spatial variability (0.313). Vegetation cover in the upper Du watershed was significantly improved after the implementation of the Grain-for-Green project. The average area-specific sediment yields (SSY) for the four SPs were 15.4, 65.5, 55.8, and 286.2 t km-2 before reforestation and decreased to 6.0, 59.3, 43.7 and 89.9 t km-2, respectively, after reforestation. ANOVA (analysis of variance) indicated that reforestation resulted in a significant reduction in runoff coefficient under SPIII and SPIV and a significant reduction in SSY under SPI and SPIV. A hysteresis analysis suggested that the proportion of events with a clockwise loop increased from 64.9% before reforestation to 82.1% after reforestation and that complex loops became less common during 2000-2010 under SPIV, thereby implying a reduced sediment supply.

Abstract
Background Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare and life-threatening condition with poor prognosis in patients with antiphospholipid syndrome (APS). Pulmonary thromboendarterectomy (PTE) is the optimal surgical option for CTEPH. Objectives This retrospective cohort study aimed to evaluate the efficacy and risk of PTE in patients with APS-associated CTEPH. Methods Consecutive patients with APS-associated CTEPH diagnosed between January 2012 and September 2017 at Peking Union Medical College Hospital were retrospectively evaluated. Demographics, clinical manifestations, antiphospholipid antibody (aPL) profiles, and pulmonary arterial hypertension–targeted medications were collected. Deterioration of cardiac function and death were chosen as the endpoints, in order to assess the effect of PTE on short-term and long-term prognoses (evaluated by the change of cardiac function after treatment and cardiac deterioration or death in the follow-up, respectively). Results A total of 20 patients with APS-associated CTEPH were enrolled, and eight patients underwent PTE. Chi-square test ( p = 0.01) and Kaplan–Meier curves (log rank test, p = 0.04) showed that there were statistically significant differences in both short-term and long-term prognoses between patients with and without PTE. Conclusion These results provide strong evidence that PTE is a curative resolution in patients with APS-associated CTEPH. Following a full specialized and multidisciplinary risk-benefit evaluation to limit the risk of thrombosis or bleeding and to manage possible thrombocytopenia, PTE is at least a temporal curative resolution for CTEPH complicated with APS.

Abstract
Cancer-specific drug delivery represents an attractive approach to preventing undesirable side effects and increasing the accumulation of the drug in tumors. The surface modification of selenium nanoparticles (SeNPs) with targeting moieties thus represents an effective strategy for cancer therapy. In this study, SeNPs were modified with folic acid (FA), whose receptors were overexpressed on the surface of cancer cells, including human cervical carcinoma HeLa cells, to fabricate tumor-targeting delivery carrier FA-SeNPs nanoparticles. Then, the anticancer drug doxorubicin (DOX) was loaded onto the surface of the FA-SeNPs for improving the antitumor efficacy of DOX in human cervical carcinoma therapy. The chemical structure characterization of FA-Se@DOX showed that DOX was successfully loaded to the surface of FA-SeNPs to prepare FA-Se@DOX nanoparticles. FA-Se@DOX exhibited significant cellular uptake in human cervical carcinoma HeLa cells (folate receptor overexpressing cells) in comparison with lung cancer A549 cells (folate receptor deficiency cells), and entered HeLa cells mainly by the clathrin-mediated endocytosis pathway. Compared to free DOX or Se@DOX at the equivalent dose of DOX, FA-Se@DOX showed obvious activity to inhibit HeLa cells' proliferation and induce the apoptosis of HeLa cells. More importantly, FA-Se@DOX could specifically accumulate in the tumor site, which contributed to the significant antitumor efficacy of FA-Se@DOX in vivo. Taken together, FA-Se@DOX may be one novel promising drug candidate for human cervical carcinoma therapy.

MATERIALS AND METHODS Here, SeNPs were modified with cyclic peptide (Arg-Gly-Asp-d-Phe-Cys [RGDfC]) to fabricate tumor-targeting delivery carrier RGDfC-SeNPs and, then, doxorubicin (DOX) was loaded to the surface of RGDfC-SeNPs for improving the antitumor efficacy of DOX in non-small-cell lung carcinoma therapy. RESULTS The chemical structure characterization of RGDfC-Se@DOX showed that DOX was successfully loaded to the surface of RGDfC-SeNPs to prepare functionalized antitumor drug delivery system RGDfC-Se@DOX. RGDfC-Se@DOX exhibited effective cellular uptake in A549 cells and entered A549 cells mainly by clathrin-mediated endocytosis pathway. Compared to free DOX or Se@DOX at the equivalent dose of DOX, RGDfC-Se@DOX showed greater activity to inhibit A549 cells' proliferation and migration/invasion and induce A549 cells' apoptosis. More importantly, compared with passive targeting delivery system Se@DOX, active targeting delivery system RGDfC-Se@DOX exhibited more significant antitumor efficacy in vivo. CONCLUSION Taken together, RGDfC-Se@DOX may be a novel promising drug candidate for the lung carcinoma therapy.

Abstract
INTRODUCTION Ribavirin (RBV) is a broad-spectrum antiviral drug. Selenium nanoparticles (SeNPs) attract much attention in the biomedical field and are used as carriers of drugs in current research studies. In this study, SeNPs were decorated by RBV, and the novel nanoparticle system was well characterized. Madin-Darby Canine Kidney cells were infected with H1N1 influenza virus before treatment with RBV, SeNPs, and SeNPs loaded with RBV (Se@RBV). METHODS AND RESULTS MTT assay showed that Se@RBV nanoparticles protect cells during H1N1 infection in vitro. Se@RBV depressed virus titer in the culture supernatant. Intracellular localization detection revealed that Se@RBV accumulated in lysosome and escaped to cytoplasm as time elapsed. Furthermore, activation of caspase-3 was resisted by Se@RBV. Expressions of proteins related to caspase-3, including cleaved poly-ADP-ribose polymerase, caspase-8, and Bax, were downregulated evidently after treatment with Se@RBV compared with the untreated infection group. In addition, phosphorylations of phosphorylated 38 (p38), JNK, and phosphorylated 53 (p53) were inhibited as well. In vivo experiments indicated that Se@RBV was found to prevent lung injury in H1N1-infected mice through hematoxylin and eosin staining. Tunel test of lung tissues present that DNA damage reached a high level but reduced substantially when treated with Se@RBV. Immunohistochemical test revealed an identical result with the in vitro experiment that activations of caspase-3 and proteins on the apoptosis pathway were restrained by Se@RBV treatment. CONCLUSION Taken together, this study elaborates that Se@RBV is a novel promising agent against H1N1 influenza virus infection.

Abstract
There is still no effective clinical antiviral drug against human enterovirus 71 (EV71) infection, which causes hand, foot and mouth disease (HFMD) in children. Scavenger receptor class B member 2 (SCARB2) is an important receptor of EV71 as it plays a vital role in the early steps of viral infection. In this study, recombinant SCARB2 protein was expressed and purified in a prokaryotic expression system, and was identified by western blot with a monoclonal antibody and mass spectrometry analysis. Detection of the sera from mice immunized with the recombinant SCARB2 protein using ELISA and western blot showed good immunogenicity of the recombinant protein. Furthermore, in the neutralization test cytopathic effect was significantly decreased when EV71 was incubated with the immune sera before infection. In summary, the SCARB2 protein was expressed successfully, and the immune sera showed obvious antiviral effect against EV71. This study provides useful information about the interaction mechanism between SCARB2 and EV71, and is also helpful for further clinical treatment research of HFMD.

Abstract
BACKGROUND AND OBJECTIVE Asthma is a complex and heterogeneous disease. We found gene-gene interactions between IL13 rs20541, IL4 rs2243250, ADRB2 rs1042713, and FCER1B rs569108 in asthmatic Chinese Han children. This 4-locus set constituted an optimal statistical interaction model. We examined associations between the 4-gene model (IL13, IL4, FCER1B, and ADRB2) and the Asthma Predictive Index (API) and atopy in Chinese Han children. METHODS Four single-nucleotide polymorphisms in the 4 genes were genotyped in 385 preschool children with wheezing symptoms using matrix-assisted laser desorption ionization time-of-flight mass spectrometry. The t test and x2 tests were used for the analysis. RESULTS Significant correlations were found between the 4-locus gene model and a stringent and loose API (both P<.0001). Additionally, a high-risk asthma genotype was a risk factor for a positive API (stringent API, OR=4.08; loose API, OR=2.36). We also found a statistically significant association between the 4-locus gene model and atopy (P<.01, OR=2.09). CONCLUSIONS Our results indicated that the 4-locus gene model consisting of L13 rs20541, IL4 rs2243250, ADRB2 rs1042713, and FCER1B rs569108 was associated with the API and atopy. These findings provide evidence that this gene model can be used to determine a high risk of developing asthma and atopy in Chinese Han children.
