Abstract
BackgroundNutritional status is closely associated with a person’s physical condition. As for patients with autoimmune disease, nutritional status may affect the balance of immune system, which successively affects disease activity.ObjectivesThe prognostic nutritional index (PNI), nutritional risk index (NRI), controlling nutritional status (CONUT) score and body mass index (BMI) are four widely used nutritional indices [1]. This study aimed to investigate the relationship between nutritional status and disease activity of rheumatoid arthritis (RA).Methods168 RA patients and 50 healthy volunteers were retrospectively enrolled. According to the disease activity score using 28 joint counts-erythrocyte sedimentation rate (DAS28-ESR), the cohort of RA patients was divided into the lower disease activity groups (DAS28-ESR≤3.2) and the higher disease activity groups (DAS28-ESR>3.2). We recorded clinical assessment and laboratory data for further analysis. Spearman’s correlation, receiver operation characteristic (ROC) curves, binary logistic regression analysis were carried out.ResultsCompared to the higher disease activity group, the lower disease activity group had low-level total protein (TP), ESR and CRP (all P<0.05), while high-level albumin and PNI (all P<0.05). PNI and NRI were negatively correlated with DAS28-ESR (r=-0.395, and r=-0.200, all P<0.05), while CONUT score was positively correlated with DAS28-ESR (r=0.324, P<0.05). ROC curve illustrated that area under the curve (AUC) of PNI for RA patients with higher disease activity was superior to NRI, CONUT score and BMI. The AUC of PNI was 0.693.Figure 1.The diagnostic value of variables for disease activity in rheumatoid arthritis using ROC curveTable 1.The correlation between nutritional indices and disease activity score using 28 joint counts-erythrocyte sedimentation rate (DAS28-ESR)PNINRICONUT scoreBMIrP valuerP valuerP valuerP valueNeutrophil(×109/L)-0.0610.4340.0450.5680.0250.7570.0790.313Monocyte(×109/L)0.1830.1630.1450.064-0.1040.1930.1520.052Lymphocyte(×109/L)0.4720.0000.2010.010-0.4360.0000.2080.007ESR (mm/h)-0.5610.000-0.2580.0010.3930.000-0.1820.020CRP (mg/L)-0.5200.000-0.0770.3260.3910.0000.0030.967RF(IU/ml)-0.2240.004-0.1160.1510.2600.001-0.0820.306CCP(IU/ml)-0.1390.088-0.2010.0140.1950.018-0.1880.022DAS28-ESR-0.3950.000-0.2000.0110.3240.000-0.1420.072ConclusionPNI may become a manageable marker for detector disease activity of RA patients.References[1]Ahn, S.S., et al., Comparison of the Clinical Implications among Five Different Nutritional Indices in Patients with Lupus Nephritis.

Abstract
599 Background: G-CSF mitigates chemotherapy-induced neutropenia (CIN) and reduces FN risk. G-CSF moves the nadir of absolute neutrophil count (ANC) earlier (to week 1) in the chemo cycle and shortens nadir duration (Crawford, NEJM 1991), suggesting the potential for suboptimal CIN protection early (week 1) in the chemo cycle. The relative FN risk in week 1 vs. weeks 2-3 of the cycle with G-CSF is unknown and was analyzed compared with no G-CSF in the real-world setting with high FN risk chemo. Methods: Using a database of administrative claims representing 100% of fee-for-service Medicare, we analyzed BC pts who initiated docetaxel (T), doxorubicin (A), or cyclophosphamide (C) monotherapy or combination therapy between 01/01/2015 – 12/31/2019. Sample pts included adults aged ≥ 65 years with continuous coverage in Medicare Parts A, B, and D for 6 months before and 20 days after chemo initiation. Pts were categorized as receiving vs. not receiving G-CSF therapy within 3 days after chemo. Rate of FN events starting in week 1 vs. weeks 2-3 in cycle 1 was calculated. We defined FN as an inpatient admission with a primary or secondary diagnosis of neutropenia and measured the interval between chemo initiation and FN admission. Results: Among 18,788 Medicare beneficiaries with BC treated with T, A, and/or C, 72% received G-CSF therapy. More pts receiving G-CSF were treated with ≥ 2 of T, A, and/or C compared to pts who did not receive G-CSF (71% vs. 51%). Overall FN incidence in cycle 1 was significantly lower among pts receiving G-CSF (4.0%; n=546) compared to pts not receiving G-CSF (8.8%; n=462) (p<0.0001). In pts with G-CSF, 81% (440/546) of all 1st-cycle FN events started in week 1 vs. 19% (106/546) in weeks 2-3. In pts not receiving G-CSF, the start of 1st-cycle FN events was more equally distributed: 41% (190/462) started in week 1 vs. 59% (272/462) in weeks 2-3. Results were robust to sensitivity analyses restricted to pts receiving ≥ 2 of T, A, and/or C. The rates of 1st-cycle FN events starting in weeks 1 and 2-3 with and without G-CSF following chemo initiation is shown below. Conclusions: Prophylactic G-CSF was highly effective for the prevention of FN in weeks 2-3, but relatively ineffective in week 1 of cycle 1 in the real-world setting, leaving pts largely unprotected during the first week. This represents an unmet medical need in week 1 of the cycle, despite use of G-CSF. Clinical trial information: NCT03294577. [Table: see text]

Abstract
Copper oxide nanoparticles (CuO NPs) show strong nano-toxic effects on organisms. Hydrogen sulphide (H2 S) plays a pivotal role in plant response to abiotic stress. In this study, we examine the crucial role of the cell wall as regulated by H2 S in response to CuO NPs stress. The digestion method was employed to determine Cu content using atomic absorption spectrometry. The TraKine pro-tubulin staining kit was used to investigate the microtubule cytoskeleton using confocal laser-scanning microscopy. Cell wall component analysis utilized the ICS-3000 HPLC system. Application of H2 S reduced growth inhibition caused by CuO NPs. Furthermore, most of the CuO NPs accumulates in roots, indicating a low transfer rate, and H2 S significantly decreased CuO NPs content in roots, leaves and stems. Subcellular distribution analysis implied most Cu accumulated in root cell walls, and that H2 S reduced the content of Cu in root cell walls. Cortical microtubules in the plasma membrane, guide cell wall biosynthesis. H2 S obviously alleviated microtubule cytoskeleton disorders caused by CuO NPs. In addition, the content of cellulose, hemicellulose, pectin and other monosaccharides in root cell walls was reduced by CuO NPs treatment. H2 S enhanced the monosaccharide and polysaccharide contents compared with that after CuO NPs treatment. In conclusion, H2 S regulates cell wall development in response to CuO NPs stress by stabilizing microtubules. H2 S affected Cu distribution and alleviated growth inhibition of tomato seedlings. The research results provide a theoretical basis for further study of nano-toxicity regulation in plants.

Abstract
BACKGROUND Acne is one of the most common skin lesions in adolescents. Some severe or inflammatory acne leads to scars, which may have major impacts on patients' quality of life or even job prospects. Grading acne plays an important role in diagnosis, and the diagnosis is made by counting the number of acne. It is a labor-intensive job and it is easy for dermatologists to make mistakes, so it is very important to develop automatic diagnosis methods. Ensemble learning may improve the prediction results of the base models, but its time complexity is relatively high. The ensemble pruning strategy may solve this computational challenge by removing the redundant base models. MATERIALS AND METHODS This study proposed a novel ensemble pruning framework of deep learning models to accurately detect and grade acne using images. First, we train multi-base models and prune the redundancy models according to the performance and diversity of the models. Then, we construct the new features of the training data by the base models we select in the previous step. Next, we remove the redundancy models further by a feature selection algorithm. Finally, we integrate all the base models by classifiers. The ensemble pruning algorithm was proposed to prune the deep learning base models. RESULTS The experimental data showed that the ensemble pruned framework achieved a prediction accuracy of 85.82% on the acne dataset, better than the existing studies. To verify our method's effectiveness, we test our method in a skin cancer dataset and greatly outperform the state-of-the-art methods. CONCLUSION The method we proposed is used to grade acne. Our method's performance outperforms state-of-the-art methods on two datasets, and it can also remove redundancy models to reduce computational complexity.

Abstract
In the surgical treatment of adenocarcinoma of the esophagogastric junction (AEG), the scope of lymph node dissection, surgical approach selection, extent of tumor resection and digestive tract reconstruction have always been controversial, with the digestive tract reconstruction in AEG facing many challenges especially. The digestive tract reconstruction is related to the extent of resection. At present, the digestive tract reconstruction after total gastrectomy includes Roux-en-Y anastomosis, jejunum interposition and its derivatives. According to different reconstruction methods, they can be divided into tube anastomosis, linear anastomosis and manual anastomosis. Anti-reflux digestive tract reconstruction after proximal gastrectomy mainly includes esophagogastric anastomosis, interposition jejunum and double channel anastomosis. At present, double channel anastomosis is the most common reconstruction method in China. Based on the concept of interposition tubular stomach and reconstruction of gastric angle for anti-reflux, we propose "Giraffe" anastomosis, which moves artificial fundus and His angle downward to retain more residual stomach, showing good gastric emptying and anti-reflux effect. In this paper, combined with our clinical experience and understanding, we discuss the selection and technical key points of digestive tract reconstruction methods in AEG, and suggest that composite anti-reflux mechanism design may be the development trend of anti-reflux reconstruction in the future. The composite mechanism includes the retention of gastric electrical pacemaker in greater curvature of the middle part of gastric body to increase the emptying capacity of residual stomach, the reconstruction of gastric fundus and His angle anti-reflux barrier, and the establishment of an interposition tubular stomach acting as a buffer zone in Giraffe construction, and so on.

Abstract
Objective: To investigate the functional outcomes and postoperative complications of Cheng's GIRAFFE reconstruction after proximal gastrectomy. Methods: A descriptive case series study was conducted. Clinical data of 100 patients with adenocarcinoma of the esophagogastric junction who underwent Cheng's GIRAFFE reconstruction after proximal gastrectomy in Cancer Hospital of University of Chinese Academy of Sciences (64 cases), Zhejiang Provincial Hospital of Chinese Medicine (24 cases), Lishui Central Hospital (10 cases), Huzhou Central Hospital (1 case) and Ningbo Lihuili Hospital (1 case) from September 2017 to June 2021 were retrospectively analyzed. Of 100 patients, 64 were males and 36 were females; the mean age was (61.3 ± 11.1) years and the BMI was (22.7±11.1) kg/m(2). For TNM stage, 68 patients were stage IA, 24 were stage IIA and 8 were stage IIB. Postoperative functional results and postoperative complications of radical gastrectomy with Giraffe reconstruction were analyzed and summarized. Gastroesophageal reflux disease questionnaire (RDQ) score and postoperative endoscopy were used to evaluate the occurrence of reflux esophagitis and its grade (grade N, grade A, grade B, grade C, and grade D from mild to severe reflux). The continuous data conforming to normal distribution were expressed as (mean ± standard deviation), and those with skewed distribution were presented as median (Q1, Q3). Results: All the 100 patients successfully completed R0 resection, including 77 patients undergoing laparoscopic surgery and 23 patients undergoing laparotomy. The Giraffe anastomosis time was (38.6±14.0) min; the blood loss was (73.0±18.4) ml; the postoperative hospital stay was 9.5 (8.2, 13.0) d; the hospitalization cost was (6.0±0.3) ten thousand yuan. Fourteen cases developed perioperative complications (14.0%), including 7 cases of pleural effusion or pneumonia, 3 cases of anastomotic leakage, 2 cases of gastric emptying disorder, 1 case of gastrointestinal hemorrhage and 1 case of anastomotic stenosis, who were all improved and discharged after symptomatic management. Patients were followed up for (33.3±1.6) months. Eight patients were found to have reflux symptoms by RDQ scale six months after surgery, and 11 patients (11/100,11.0%) were found to have reflux esophagitis by gastroscopy, including 6 in grade A, 3 in grade B, and 2 in grade C. All the patients could control their reflux symptoms with behavioral guidance or oral PPIs. Conclusion: Cheng's GIRAFFE reconstruction has good anti-reflux efficacy and gastric emptying function; it can be one of the choices of reconstruction methods after proximal gastrectomy.

Abstract
Objective: To investigate whether pre-lingual deafness adult caused by inadequate auditory compensation in childhood can benefit from cochlear implants and the related influencing factors. Methods: A total of 26 prelingual deafness as experimental group [11 males and 15 females, the age of operation was (24.5±5.7) years] and 13 postlingual deafness as control group [5 males and 8 females, the age at the time of operation was (42.2±11.4) years] were recruited. Objective assessment included hearing threshold and speech recognition rate tests while wearing cochlear implants. Subjective assessment used Nijmegen Cochlear Implant Questionnaire to assess hearing-related quality of life of subjects. The changes of hearing ability in the prelingual deafness group before and after operation and the differences with the postlingual deafness group were compared, and the correlation between speech recognition ability and the age diagnosed as severe or profound deafness, the age of hearing aid invalid, and duration of wearing cochlear implant were analyzed as factor indicators. All statistical results were analyzed by SAS 9.4 software. Results: In terms of objective indicators, the speech recognition rate of pre-lingual deafness was significantly lower than that of post-lingual deafness [(35.4±28.0)% vs (80.9±8.0)%,t=7.67, P<0.001], while there was no statistical difference in hearing threshold between the two groups [(34.8±4.0) dB HL vs (33.1±3.7) dB HL, t=1.30, P>0.05]. The indicators in the subjective questionnaire showed that the prelingual deafness group was only weaker in advanced sound perception, confidence and total mean score than the post-lingual deafness group (P<0.05), and there was no significant difference in other aspects(P>0.05), meanwhile, all indicators of the prelingual deafness group were significantly improved compared with the preoperative level (P<0.001). There was a moderate positive correlation between the hearing quality and the speech recognition rate in the prelingual deafness group(r=0.51, P=0.008). The regression analysis showed that the invalid age of hearing aid was the exact influencing factor of speech recognition rate. Conclusions: Certain prelingual deaf adults can adapt to cochlear implants and obtain different degrees of auditory assistance. Compared with the improvement of objective auditory ability assessment, the patient who received cochlear implantation gain more improvement in auditory related quality of life subjectively. The ineffective age of preoperative hearing aid is an important factor, which needs to be aroused sufficient preoperative attention.

Abstract
Background: With advancements in periodontal medicine, the relationship between periodontitis and systemic diseases has garnered increasing attention. Recently, emerging evidence has indicated that periodontitis may be involved in the pathogenesis of Alzheimer’s disease (AD). Objective: To assess the impact of experimental periodontitis on cognitive function deficits in a rat model of streptozotocin-induced AD and determine the mechanisms underlying these effects. Methods: Rats were randomly assigned to the control (C), experimental periodontitis (P), Alzheimer’s disease (AD), and experimental periodontitis with streptozotocin-induced AD (AD-P) groups. Experimental periodontitis was induced using ligation and coating with Porphyromonas gingivalis. In the AD-P group, AD was induced by intracerebroventricular injection of streptozotocin after 6 weeks of experimental periodontitis induction. Results: Compared with the group C rats, those in group P exhibited alveolar bone resorption, learning and memory function impairment, and decreased insulin sensitivity and insulin signaling-related protein expression. Glial cell activation and cognitive impairment in streptozotocin-induced groups with significantly increased phosphorylated tau levels were more pronounced relative to the C group. The number of neurons and insulin sensitivity and insulin signaling-related protein expression in group AD-P rats were lower than those in the AD alone group, while the expressions of glial fibrillary acidic protein, tau phosphorylation, interleukin-6, and cyclooxygenase-2 were significantly increased. Conclusion: Periodontitis may be a risk factor exacerbating cognitive deficits in an AD-like neurodegenerative context, possibly by impairing the insulin signaling pathway and stimulating gliosis and neuroinflammation.

Abstract
Human Leukocyte Antigen (HLA) is a type of molecule residing on the surfaces of most human cells and exerts an essential role in the immune system responding to the invasive items. The T cell antigen receptors may recognize the HLA-peptide complexes on the surfaces of cancer cells and destroy these cancer cells through toxic T lymphocytes. The computational determination of HLA-binding peptides will facilitate the rapid development of cancer immunotherapies. This study hypothesized that the natural language processing-encoded peptide features may be further enriched by another deep neural network. The hypothesis was tested with the Bi-directional Long Short-Term Memory-extracted features from the pretrained Protein Bidirectional Encoder Representations from Transformers-encoded features of the class I HLA (HLA-I)-binding peptides. The experimental data showed that our proposed HLAB feature engineering algorithm outperformed the existing ones in detecting the HLA-I-binding peptides. The extensive evaluation data show that the proposed HLAB algorithm outperforms all the seven existing studies on predicting the peptides binding to the HLA-A*01:01 allele in AUC and achieves the best average AUC values on the six out of the seven k-mers (k=8,9,...,14, respectively represent the prediction task of a polypeptide consisting of k amino acids) except for the 9-mer prediction tasks. The source code and the fine-tuned feature extraction models are available at http://www.healthinformaticslab.org/supp/resources.php.

Abstract
The Portevin-Le Châtelier (PLC) effect in a powder metallurgy (PM) Co-Ni-based superalloy was systematically investigated via the tensile tests at temperatures ranging from 200 to 600 °C and strain rates at 1.0 × 10-4 to 1.0 × 10-2. Both normal and inverse PLC effects were observed in the PLC regime, and the former appeared in the A and B types at a low temperature, whilst the latter appeared in the C type at an elevated temperature. Both positive and negative strain rate sensitivities (SRS) were shown in PLC regime, and SRS should be derived from same types of serrations. Based on the calculated activation energy, the substitutional atom Mo is considered to take primary responsibility for the PLC effect in present alloy.

Abstract
In this paper, high-grade serous ovarian cancer (HGSOC) is studied, which is the most common histological subtype of ovarian cancer. We use a new analytical procedure to combine the bulk RNA-Seq sample for ovarian cancer, mRNA expression-based stemness index (mRNAsi), and single-cell data for ovarian cancer. Through integrating bulk RNA-Seq sample of cancer samples from TCGA, UCSC Xena and single-cell RNA-Seq (scRNA-Seq) data of HGSOC from GEO, and performing a series of computational analyses on them, we identify stemness markers and survival-related markers, explore stem cell populations in ovarian cancer, and provide potential treatment recommendation. As a result, 171 key genes for capturing stem cell characteristics are screened and one vital cancer stem cell subpopulation is identified. Through further analysis of these key genes and cancer stem cell subpopulation, more critical genes can be obtained as LCP2, FCGR3A, COL1A1, COL1A2, MT-CYB, CCT5, and PAPPA, are closely associated with ovarian cancer. So these genes have the potential to be used as prognostic biomarkers for ovarian cancer.

Abstract
Chronic obstructive pulmonary disease (COPD) has become the third leading cause of global death. Insufficiency in early diagnosis and treatment of COPD, especially COPD exacerbations, leads to a tremendous economic burden and medical costs. A cost-effective and timely prevention requires decentralized point-of-care diagnostics at patients' residences at affordable prices. Advances in point-of-care (POC) diagnostics may offer new solutions to reduce medical expenditures by measuring salivary and blood biomarkers. Among them, paper-based analytical devices have been the most promising candidates due to their advantages of being affordable, biocompatible, disposable, scalable, and easy to modify. In this review, we present salivary and blood biomarkers related to COPD endotypes and exacerbations, summarize current technologies to collect human whole saliva and whole blood samples, evaluate state-of-the-art paper-based analytical devices that detect COPD biomarkers in saliva and blood, and discuss existing challenges with outlooks on future paper-based POC systems for COPD diagnosis and management.

Abstract
This study presents a complete structural model of TcdA holotoxin and sheds new lights into the conformational dynamics of TcdA and its roles in TcdA intoxication. Clostridioides difficile toxin A and B (TcdA and TcdB) are two major virulence factors responsible for diseases associated with C. difficile infection (CDI). Here, we report the 3.18-Å resolution crystal structure of a TcdA fragment (residues L843–T2481), which advances our understanding of the complete structure of TcdA holotoxin. Our structural analysis, together with complementary single molecule FRET and limited proteolysis studies, reveal that TcdA adopts a dynamic structure and its CROPs domain can sample a spectrum of open and closed conformations in a pH-dependent manner. Furthermore, a small globular subdomain (SGS) and the CROPs protect the pore-forming region of TcdA in the closed state at neutral pH, which could contribute to modulating the pH-dependent pore formation of TcdA. A rationally designed TcdA mutation that trapped the CROPs in the closed conformation showed drastically reduced cytotoxicity. Taken together, these studies shed new lights into the conformational dynamics of TcdA and its roles in TcdA intoxication.

Abstract
Little is known about functional recovery following patient discharge in an established enhanced recovery programme after video-assisted thoracoscopic lobectomy. We conducted a single-centre pilot prospective observational cohort study. We hypothesised that patients achieved early functional recovery after discharge. A total of 32 patients aged ≥ 18 years were enrolled. A digital device was used for objective activity measurements, and patient-reported outcomes were collected as subjective measurements. Primary outcomes were the difference in physical activity; sleep duration; pain; fatigue; and average quality of life scores between pre-operative baseline and 7 days following discharge. The secondary outcome was the reason for reduced daily activity during the first 7 days after discharge. Median (IQR [range]) length of stay was 3 (2-5 [1-13]) days. Up to post-discharge day 7, total, lower intensity and moderate-to-vigorous activities were lower than pre-operative activity (p < 0.001; p = 0.005 and p = 0.027, respectively). Numerical rating scale (0-10) pain scores increased postoperatively at rest (mean difference 1.2, p < 0.001) and during walking (mean difference 1.4, p < 0.001). Fatigue assessed by the Christensen Fatigue Scale (1-10) was also increased postoperatively (mean difference 1.7, p = 0.001). There was a reduction in quality of life scores, while sedentary activity and sleep duration were unchanged postoperatively. Dominant reasons for not recovering daily activity included fatigue in 43% and pain in 33% of patients. Despite compliance with an enhanced recovery programme with a median length of hospital stay of 3 days after video-assisted thoracoscopic lobectomy, functional recovery was not achieved within 7 days after hospital discharge. Reduction in postoperative pain and fatigue are important factors to enhance functional recovery.

Abstract
Cross-linking mass spectrometry (XL-MS) is an emergent technology for studying protein-protein interactions (PPIs) and elucidating architectures of protein complexes. The development of various MS-cleavable cross-linkers has facilitated the identification of cross-linked peptides, enabling XL-MS studies at the systems level. However, the scope and depth of cellular networks revealed by current XL-MS technologies remain limited. Due to the inherently broad dynamic range and complexity of proteomes, interference from highly abundant proteins impedes the identification of low-abundance cross-linked peptides in complex samples. Thus, peptide enrichment prior to MS analysis is necessary to enhance cross-link identification for proteome-wide studies. Although chromatographic techniques including size exclusion (SEC) and strong cation exchange (SCX) have been successful in isolating cross-linked peptides, new fractionation methods are still needed to further improve the depth of PPI mapping. Here, we present a two-dimensional (2D) separation strategy by integrating peptide SEC with tip-based high pH reverse-phase (HpHt) fractionation to expand the coverage of proteome-wide XL-MS analyses. Combined with the MS-cleavable cross-linker DSSO, we have successfully mapped in vitro PPIs from HEK293 cell lysates with improved identification of cross-linked peptides compared to existing approaches. The method developed here is effective and can be generalized for cross-linking studies of complex samples.

Abstract
Background Emerging evidence suggests that secreted phosphoprotein 1 (SPP1) is involved in tumor cell progression in multiple cancer types. However, the role of SPP1 in different cancers is still not clear. Methods We used data from The Cancer Genome Atlas (TCGA) to analyze the multiomic roles of SPP1, including RNA expression, DNA methylation, protein phosphorylation, immune infiltration, and overall survival (OS) in 33 tumor types. Results SPP1 is highly expressed in most cancer types, and its methylation variability and mRNA expression level are both correlated with prognosis in multiple cancer types. A higher S234 phosphorylation level was observed in 4 types of tumors, including colon adenocarcinoma (COAD) and lung adenocarcinoma (LUAD). SPP1 expression level was positively associated with the infiltration level of dendritic cells, neutrophils, and macrophages in multiple cancer types. It was also significantly positively correlated with hepatitis A virus cellular receptor 2 (HAVCR2), which was observed in most tumor types, including brain lower grade glioma (LGG) and ovarian serous cystadenocarcinoma (OV). Moreover, myeloid cell differentiation and leukocyte migration were observed in the enrichment analysis, suggesting that SPP1 might induce immune escape. Conclusions Pan-cancer analysis using a multiomic approach offered a comprehensive overview of SPP1. This protein plays an important role in most of the analyzed tumor types and could be a valuable prognostic marker across different types of cancer.

Abstract
In recent years, cross-linking mass spectrometry (XL-MS) has made enormous strides as a technology for probing protein-protein interactions (PPIs) and elucidating architectures of multisubunit assemblies. To define conformational and interaction dynamics of protein complexes under different physiological conditions, various quantitative cross-linking mass spectrometry (QXL-MS) strategies based on stable isotope labeling have been developed. These QXL-MS approaches have effectively allowed comparative analysis of cross-links to determine their relative abundance changes at global scales. Although successful, it remains challenging to consistently obtain quantitative measurements on low-abundant cross-links. Therefore, targeted QXL-MS is needed to enable MS "Western" analysis of cross-links to enhance sensitivity and reliability in quantitation. To this end, we have established a robust parallel reaction monitoring (PRM)-based targeted QXL-MS platform using sulfoxide-containing MS-cleavable cross-linker disuccinimidyl sulfoxide (DSSO), permitting label-free comparative analysis of selected cross-links across multiple samples. In addition, we have applied this methodology to study phosphorylation-dependent conformational dynamics of the human 26S proteasome. The PRM-based targeted QXL-MS analytical platform described here is applicable for all sulfoxide-containing MS-cleavable cross-linkers and can be directly adopted for comparative studies of protein-protein interactions in various cellular contexts.

Abstract
Objective: To explore the clinical application value of two longitudes three transverses method in the location of the perforator of thoracodorsal artery perforator and deep wound repair. Methods: The retrospectively observational study was conducted. From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. Results: The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. Conclusions: The two longitudes three transverses method is helpful to locate the perforator of thoracodorsal artery perforator flap. The method is simple and reliable. The thoracodorsal artery perforator flap designed and harvested based on this method has good clinical effects in repairing deep wound, with minimal donor site damage.

Abstract
Clinical trials have indicated that thalidomide could be used to treat thalassemia, but evidence of changes in liver iron burden and liver volume during thalidomide treatment is lacking. This study aimed to evaluate the liver iron burden and volume changes following thalidomide treatment in patients with transfusion-dependent ß-thalassemia. A total of 66 participants with transfusion-dependent ß-thalassemia were included in this prospective cohort study between January 2017 and December 2020. Patients were treated with thalidomide (150–200 mg/day) plus conventional therapy. Liver volume, liver R2*, and hepatic muscle signal ratio (SIR)_T1 and SIR_T2 were measured with magnetic resonance imaging (MRI), and serum ferritin, hemoglobin, erythrocyte and platelet counts, and liver function were measured at baseline and at the 3rd and 12th months. Adverse events were also noted. Patients showed progressive increase in hemoglobin, erythrocyte, platelet count, SIR_T1, and SIR_T2 during the 12-months follow up. Serum ferritin, R2*, and liver volume progressively decreased during the follow up. The R2* value had a significantly positive correlation with serum ferritin, and SIR_T1 and SIR_T2 had a significantly negative correlation with serum ferritin. No serious adverse events were observed. This study showed that thalidomide could potentially be used to successfully treat patients with transfusion-dependent ß-thalassemia; the liver iron burden and liver volume could be relieved during treatment, and the MRI-measured R2*, SIR_T1, and SIR_T2 may be used to noninvasively monitor liver iron concentration.

Abstract
Abstract
Introduction Bone pain is a debilitating adverse reaction associated with G-CSF (including Peg) in Breast Cancer (BC) pts receiving chemotherapy (Chemo). G-CSF shortens the time to, duration of, and depth of the neutrophil (ANC) nadir, associated with an acceleration of hematopoietic stem cell differentiation into mature neutrophils (Crawford NEJM 1991). We hypothesized that this acceleration is accompanied by an expansion of bone intramedullary contents (including hematopoietic precursors) and can lead to an increase in intra-cavitary pressure and stimulation of intra-osseous Aδ mechano-nociceptors, which are transmitted as pain sensations through Piezo2 signaling to the brain (Nencini and Ivanusic, 2017; Oostinga Bone 2020). Plinabulin (Plin) is a novel, non-G-CSF, small molecule agent with anticancer activity, that also prevents chemotherapy-induced neutropenia (CIN). Plin has a fast onset mechanism of action (MoA) for CIN-prevention acting in the first week of the cycle, whereas Peg has a slow MoA, acting in the second week of the cycle. Combining Plin+Peg resulted in superior CIN prevention, significantly higher ANC nadir and significantly less bone pain (Blayney ASCO 2020; St Gallen 2019). Method Data from the randomized, double-blinded trial PROTECTIVE-2 (NCT0329457) evaluating CIN outcomes with the Plin+Peg combination (n=111) vs Peg alone (n=110) in BC pts receiving TAC were analyzed for timing of bone pain occurrence relative to ANC Nadir, and whether maximum bone pain score was correlated (inversely) with ANC nadir. Patient reported outcome (PRO) bone pain scores were from validated Numerical Rate Scale (NRS)-based questionnaires. Bone AEs were obtained from case report forms. ANC Nadir was evaluated from central laboratory (COVANCE) assessments of almost daily ANC assessments. Results ANC declined rapidly between Day 3 and Day 7 (the time point of ANC nadir in both groups) and significantly steeper with Peg vs Peg+Plin (P<0.013). ANC nadir reached lower levels with Peg vs Plin+Peg: 0.32 vs 0.54 x10E9/L (p=0.0002). Peak bone pain score (NRS method) occurred around Day 5 and was significantly (P<0.05) higher for Peg vs Plin+ Peg Bone pain score (NRS) plotted against the absolute neutrophil count at time of nadir, demonstrated and inverse and statistically significant correlation (p=0.019). The Peg alone group had significantly higher bone pain AE frequency over 4 cycles vs Plin+Peg (30% vs 18%; p=0.03). Conclusion The collective data supports the concept that bone pain in pts receiving myelosuppressive chemotherapy and Peg is a direct consequence of accelerated drop in ANC and to deeper levels by Peg, triggering an accelerated intramedullary compensatory hematopoietic response and associate pressure build up that sensed as bone pain. The addition of Plin to Peg slowed down the Peg-induced speed and deepening of ANC decline, and consequently ameliorates this intramedullary response mechanism and bone pain generation.

Abstract
Introduction TAC chemotherapy may have better survival outcomes than TC or AC, but is used less often likely because of toxicity and reduced HrQoL (Fujii Jama Oncol 2005; Martin Annals of Oncol 2006). Combination Plin+Peg is superior to Peg alone for the prevention of chemotherapy-induced-neutropenia (CIN): 68% vs 86% grade (Gr) 4 neutropenia with Plin+Peg vs Peg (P=0.0015). FN rate was 3.6% vs 6.3% for Plin+Peg vs Peg. Here we analyzed the mitigating effects of Plin on toxicity and HrQoL impacted by adjuvant TAC in BC pts also receiving Peg. Methods In the randomized, double-blinded trial PROTECTIVE-2 (NCT0329457), Stage I,II,III BC pts received TAC (T dose 75mg/m2, A dose 50 mg/m2, C dose 500 mg/m2) with either the Plin+Peg combination (n=110) or Peg alone (n=111) for 4 cycles. Toxicity was evaluated by central laboratory (Covance) hematology and chemistry assessments, AE collection and 12-lead ECG. HrQoL was assessed by EORTC QLQ-C30 and EQ-5D-5L. pCR rate was assessed by pathological evaluation of excised BC tissue after surgery. Pts with abnormal cardiac function meeting any of the following criteria were excluded: 1. Prior doxorubicin (>240 mg/m2) or anthracycline exposure; 2. Cardiac ventricular dysfunction; 3. LVEF≤50%; 4. Congestive heart failure of NYHA Class II,III, IV cardiac disease; 5. History of myocardial infarction or coronary artery disease; 6. ECG findings consistent with active ischemic heart disease; angina pectoris requiring medication; 7. Arrhythmia requiring medication; severe conduction anomaly; 8. History of congenital QT prolongation; 9. Significant cardiac valvular disease; 10. Uncontrolled hypertension. Plin 40 mg fixed dose was given on day 1 (the day of TAC administration), and peg 6mg was given on day 2. Results All grade (Gr) AE frequency was 97% vs 96% in Plin+Peg vs Peg. However a shift to lower grade was noted. Gr 4 AE frequency was lower with Plin+ Peg vs Peg: 59% vs 80% (p<0.03). Gr3 (18% vs 6%) and Gr 2 (19% vs 9%) frequency was higher with Plin+Peg vs Peg. EQ-5D-5L utility values over all cycles had slightly increased with Plin+Peg, but steadily decreased with Peg alone (see table); Day -1 represent the score on the date before TAC dosing. ⋯add more HrQoL data⋯.pCR rates was numerically higher with Plin+Peg vs Peg (13.04% vs 12.5%). No cardiac dysfunction-related AEs were noted with Plin+Peg or Peg.
Conclusion The addition of Plin to Peg for CIN prevention enables better management of TAC induced toxicity and HrQoL. TAC should be reevaluated in early stage BC patients in light of the improved outcomes with Plin+Peg support.

Abstract
Statins play a major role in reducing circulating cholesterol levels and are widely used to prevent coronary artery disease. Although they are recently confirmed to up-regulate mitophagy, little is known about the molecular mechanisms and its effect on endothelial progenitor cell (EPC). Here, we explore the role and mechanism underlying statin (pitavastatin, PTV)-activated mitophagy in EPC proliferation. ApoE−/− mice are fed a high-fat diet for 8 weeks to induce atherosclerosis. In these mice, EPC proliferation decreases and is accompanied by mitochondrial dysfunction and mitophagy impairment via the PINK1-PARK2 pathway. PTV reverses mitophagy and reduction in proliferation. Pink1 knockout or silencing Atg7 blocks PTV-induced proliferation improvement, suggesting that mitophagy contributes to the EPC proliferation increase. PTV elicits mitochondrial calcium release into the cytoplasm and further phosphorylates CAMK1. Phosphorylated CAMK1 contributes to PINK1 phosphorylation as well as mitophagy and mitochondrial function recover in EPCs. Together, our findings describe a molecular mechanism of mitophagy activation, where mitochondrial calcium release promotes CAMK1 phosphorylation of threonine177 before phosphorylation of PINK1 at serine228, which recruits PARK2 and phosphorylates its serine65 to activate mitophagy. Our results further account for the pleiotropic effects of statins on the cardiovascular system and provide a promising and potential therapeutic target for atherosclerosis. Endothelial progenitor cell (EPCs) proliferation decreased, accompanied by mitochondrial dysfunction and mitophagy impairment via the PINK1-PARK2 pathway in atherosclerosis. Statins induce mitophagy to protect EPCs by mitochondrial calcium release and CAMK1-mediated PINK1 phosphorylation.

Abstract
Hypertension is the most common comorbidity in patients with coronavirus disease 2019 (COVID‐19) and increases in‐hospital mortality. Day‐by‐day blood pressure (BP) variability (BPV) is associated with clinical outcomes in hypertensive patients. However, little information is available on the association of BPV with the outcomes of COVID‐19 patients with hypertension. This study aimed to demonstrate whether day‐by‐day in‐hospital BPV had prognostic significance in these patients. The authors included 702 COVID‐19 patients with hypertension from Huoshenshan Hospital (Wuhan, China), who underwent valid in‐hospital BP measurements on at least seven consecutive days. Day‐by‐day BPV was assessed by standard deviation (SD), coefficient of variation (CV), and variation independent of mean (VIM). Overall, patients with severe COVID‐19 and non‐survivors had higher BPV than moderate cases and survivors, respectively. Additionally, higher BPV was correlated with greater age and higher levels of C‐reactive protein, procalcitonin, high‐sensitive cardiac troponin I, and B‐type natriuretic peptide. In multivariable Cox regression, SD of systolic BP (SBP) was predictive of mortality [hazard ratio (HR) 1.17, 95% confidence interval (CI) 1.05–1.30] as well as acute respiratory distress syndrome (ARDS) (HR 1.09, 95% CI 1.01–1.16). Similar trends were observed for CV and VIM of SBP, but not indices of diastolic BP variability. The authors demonstrated that day‐by‐day in‐hospital SBP variability can independently predict mortality and ARDS in COVID‐19 patients with hypertension. And high BPV might be correlated with severe inflammation and myocardial injury. Further studies are needed to clarify whether early reduction of BPV will improve the prognosis of these patients.

Abstract
MOTIVATION Predicting disease-related long non-coding RNAs (lncRNAs) can be used as the biomarkers for disease diagnosis and treatment. The development of effective computational prediction approaches to predict lncRNA-disease associations (LDAs) can provide insights into the pathogenesis of complex human diseases and reduce experimental costs. However, few of the existing methods use microRNA (miRNA) information and consider the complex relationship between inter-graph and intra-graph in complex-graph for assisting prediction. RESULTS In this paper, the relationships between the same types of nodes and different types of nodes in complex-graph are introduced. We propose a multi-channel graph attention autoencoder model to predict LDAs, called MGATE. First, an lncRNA-miRNA-disease complex-graph is established based on the similarity and correlation among lncRNA, miRNA and diseases to integrate the complex association among them. Secondly, in order to fully extract the comprehensive information of the nodes, we use graph autoencoder networks to learn multiple representations from complex-graph, inter-graph and intra-graph. Thirdly, a graph-level attention mechanism integration module is adopted to adaptively merge the three representations, and a combined training strategy is performed to optimize the whole model to ensure the complementary and consistency among the multi-graph embedding representations. Finally, multiple classifiers are explored, and Random Forest is used to predict the association score between lncRNA and disease. Experimental results on the public dataset show that the area under receiver operating characteristic curve and area under precision-recall curve of MGATE are 0.964 and 0.413, respectively. MGATE performance significantly outperformed seven state-of-the-art methods. Furthermore, the case studies of three cancers further demonstrate the ability of MGATE to identify potential disease-correlated candidate lncRNAs.

Abstract
Microplastics (MPs) and pesticides are typical representatives of harmful chemicals in polluted waters. It is understood that the combined toxicity may differ from that of a single toxic substance. Although their combined toxicities on aquatic organisms have practical significance and research value, they have received little attention due to their complicated interaction, and the mechanism has rarely been reported. In this paper, we designed a study to investigate the single and combined effects of polystyrene microplastics (PS-MPs) and the triazole fungicide difenoconazole on zebrafish, and to explore the mechanism of this effect. The results showed that PS-MPs could reduce the bioaccumulation of difenoconazole in zebrafish to a certain extent and alleviate the oxidative stress damage of difenoconazole in the zebrafish liver. The transcriptome and qRT-PCR data revealed the association of multiple pathways in the difenoconazole response, while the presence of PS-MPs ameliorated this effect in gene expression changes. Due to the properties of PS-MPs and the interaction between them, the toxic effect of difenoconazole when combined with PS-MPs is more prominent. These results provide a novel aspect to understand the environmental behavior of MPs and to evaluate the combined effect of MPs and pesticides on aquatic food.

Abstract
Phosphoglycerate kinase 1 (PGK1) has complicated and multiple functions in cancer occurrence, tumor progression and drug resistance. Sorafenib is the first-line treatment targeted drug for patients with kidney renal clear cell carcinoma (KIRC) as a tyrosine kinase inhibitor, but sorafenib resistance is extremely common to retard therapy efficiency. So far, it is unclear whether and how PGK1 is involved in the pathogenesis and sorafenib resistance of KIRC. Herein, the molecular mechanisms of PGK1-mediated KIRC progression and sorafenib resistance have been explored by comprehensively integrative studies using biochemical approaches, mass spectrometry (MS) identification, microarray assay, nude mouse xenograft model and bioinformatics analysis. We have confirmed PGK1 is specifically upregulated in KIRC based on the transcriptome data generated by our own gene chip experiment, proteomics identification and the bioinformatics analysis for five online transcriptome datasets, and PGK1 upregulation in tumor tissues and serum is indicative with poor prognosis of KIRC patients. In the KIRC tissues, a high expression of PGK1 is often accompanied with an increase of glycolysis-related enzymes and CXCR4. PGK1 exhibits pro-tumorigenic properties in vitro and in a xenograft tumor model by accelerating glycolysis and inducing CXCR4-mediated phosphorylation of AKT and ERK. Moreover, PGK1 promotes sorafenib resistance via increasing CXCR4-mediated ERK phosphorylation. In conclusion, PGK1-invovled metabolic reprogramming and activation of CXCR4/ERK signaling pathway contributes to tumor growth and sorafenib resistance of KIRC.

Abstract
BACKGROUND AND PURPOSE Conventionally, early treatment response to stereotactic radiotherapy in intracranial tumors is often determined by structural MR imaging. Tissue sodium concentration is altered by cellular integrity and energy status in cells. In this study, we aimed to investigate the feasibility of sodium MR imaging at 7T for the preliminary evaluation of radiotherapeutic efficacy for intracranial tumors. MATERIALS AND METHODS Data were collected from 16 patients (12 men and 4 women, 24-75 years of age) with 22 intracranial tumors who were treated with stereotactic radiation therapy using CyberKnife at our institution between December 1, 2016, and August 15, 2019. Sodium MR imaging was performed at 7T before and 48 hours, 1 week, and 1 month after CyberKnife radiation therapy. Tissue sodium concentration (TSC) was calculated and analyzed based on manually labeled regions of tumors. RESULTS Ultra-high-field sodium MR imaging clearly showed the intratumoral signal, which is significantly higher than that of normal tissue (t = 5.250, P <.001)., but the edema zone has some influence. The average TSC ratios of tumor to CSF in the 22 tumors, contralateral normal tissues, edema zones, frontal cortex, and frontal white matter were 0.66 (range, 0.23-1.5), 0.30 (range, 0.15-0.43), 0.58 (range, 0.25-1.21), 0.25 (range, 0.17-0.42), and 0.30 (range, 0.19-0.49), respectively. A total of 12 tumors in 8 patients were scanned at 48 hours, 1 week, and 1 month after treatment. The average TSC at 48 hours after treatment was 0.06 higher than that before treatment and began to decrease at 1 week. The TSC ratios of 10 continued to decline and 2 tumors increased at 1 month, respectively. Tumor volume decreased by 2.4%-99% after 3 months. CONCLUSIONS Changes in the TSC can be quantified by sodium MR imaging at 7T and used to detect radiobiologic alterations in intracranial tumors at early time points after CyberKnife radiation therapy.

Abstract
This article proposes an adaptive finite-time tracking control based on fuzzy-logic systems (FLSs) for an uncertain nonstrict nonlinear multi-input-multi-output (MIMO) full-state-constrained system with the coupled uncertain dead-zone input. By using three kinds of FLSs: the uncertain system, the uncertain dead zone, and the uncertain input transfer inverse matrix are approximated using the system function FLS, dead-zone FLS, and input transfer inverse matrix FLS, respectively. After defining the barrier Lyapunov function, the fuzzy-based adaptive tracking controllers are designed, and the fuzzy weights are updated through the proposed adaptive laws. Then, based on the extended finite-time convergence theorem, with the design parameters chosen properly, the target uncertain nonlinear system is guaranteed to be semiglobal practical finite-time stable (SGPFS); and the full-state constraints are not violated while avoiding the effects of the dead zones. Furthermore, a simulation is presented to verify the validity of the proposed algorithm.

Abstract
OBJECTIVE Atherosclerosis, characterized by endothelial injury, multicellular involvement, chronic inflammation, and lipid deposition, can lead to acute cardiovascular events. N6-methyladenosine (m6A) is the most abundant, prevalent RNA modification in mammalian cells. m6A, a reversible modification, can be catalyzed by m6A methyltransferase complexes (writers), reverted by demethylases (erasers), and recognized by m6A-binding proteins (readers). Emerging evidence suggests that m6A modification plays a significant role in regulating many biological and cellular processes in atherosclerosis. In this review, we highlight the biological function of m6A modification and give a brief perspective on its future applications in atherosclerosis. MATERIALS AND METHODS This is a narrative review. The literature search strategy for indexed Scopus articles was performed randomly using PubMed and MEDLINE as the primary sources. No specific term was used. RESULTS As the mechanism of the relationship between inflammatory response and atherosclerosis, m6A has become a new focus in the study of clinical treatment strategies for atherosclerosis. METTL14-dependent m6A modification may be a target for atherosclerosis therapy. A variety of m6A regulatory factors promote the progression of atherosclerosis by regulating polarization and inflammation of macrophages. WTAP and METTL14 can affect the phenotypic modulation of VSMCs through m6A modification. CONCLUSIONS The existence of m6A in cardiovascular transcripts is necessary to maintain cardiac function, and the level of m6A modification is increased in a variety of atherosclerotic vascular cells, indicating that m6A modification is involved in the pathophysiological process of atherosclerosis. m6A modification plays an important character in atherosclerosis.

Abstract
BACKGROUND AND PURPOSE Intracranial atherosclerotic plaque features are potential factors associated with recurrent stroke, but previous studies only focused on a single lesion, and few studies investigated them with perfusion impairment. This study aimed to investigate the association among whole-brain plaque features, perfusion deficit, and stroke recurrence. MATERIALS AND METHODS Patients with ischemic stroke due to intracranial atherosclerosis were retrospectively collected and categorized into first-time and recurrent-stroke groups. Patients underwent high-resolution vessel wall imaging and DSC-PWI. Intracranial plaque number, culprit plaque features (such as plaque volume/burden, degree of stenosis, enhancement ratio), and perfusion deficit variables were recorded. Logistic regression analyses were performed to determine the independent factors associated with recurrent stroke. RESULTS One hundred seventy-five patients (mean age, 59 [SD, 12] years; 115 men) were included. Compared with the first-time stroke group (n = 100), the recurrent-stroke group (n = 75) had a larger culprit volume (P = .006) and showed more intracranial plaques (P < .001) and more enhanced plaques (P = .003). After we adjusted for other factors, culprit plaque volume (OR, 1.16 per 10-mm3 increase; 95% CI, 1.03-1.30; P = .015) and total plaque number (OR, 1.31; 95% CI, 1.13-1.52; P < .001) were independently associated with recurrent stroke. Combining these factors increased the area under the curve to 0.71. CONCLUSIONS Large culprit plaque and more intracranial plaques were independently associated with recurrent stroke. Performing whole-brain vessel wall imaging may help identify patients with a higher risk of recurrent stroke.

Abstract
Aims:
This study aims to formulate the inter-feature correlation as the engineered features.
Background:
Modern biotechnologies tend to generate a huge number of characteristics of a sample, while an OMIC dataset usually has a few dozens or hundreds of samples due to the high costs of generating the OMIC data. So many bio-OMIC studies assumed the inter-feature independence and selected a feature with a high phenotype-association.
Objective:
However, many features are closely associated with each other due to their physical or functional interactions, which may be utilized as a new view of features.
Method:
This study proposed a feature engineering algorithm based on the correlation coefficients (FeCO3) by utilizing the correlations between a given sample and a few reference samples. A comprehensive evaluation was carried out for the proposed FeCO3 network features using 24 bio-OMIC datasets.
Result:
The experimental data suggested that the newly calculated FeCO3 network features tended to achieve better classification performances than the original features, using the same popular feature selection and classification algorithms. The FeCO3 network features were also consistently supported by the literature. FeCO3 was utilized to investigate the high-order engineered biomarkers of breast cancer, and detected the PBX2 gene (Pre-B-Cell Leukemia Transcription Factor 2) as one of the candidate breast cancer biomarkers. Although the two methylated residues cg14851325 (Pvalue=8.06e-2) and cg16602460 (Pvalue=1.19e-1) within PBX2 did not have statistically significant association with breast cancers, the high-order inter-feature correlations showed a significant association with breast cancers.
Conclusion:
The proposed FeCO3 network features calculated the high-order inter-feature correlations as novel features, and may facilitate the investigations of complex diseases from this new perspective.

Abstract
The lunar nearside has been investigated by many uncrewed and crewed missions, but the farside of the Moon remains poorly known. Lunar farside exploration is challenging because maneuvering rovers with efficient locomotion in harsh extraterrestrial environment is necessary to explore geological characteristics of scientific interest. Chang'E-4 mission successfully targeted the Moon's farside and deployed a teleoperated rover (Yutu-2) to explore inside the Von Kármán crater, conveying rich information regarding regolith, craters, and rocks. Here, we report mobile exploration on the lunar farside with Yutu-2 over the initial 2 years. During its journey, Yutu-2 has experienced varying degrees of mild slip and skid, indicating that the terrain is relatively flat at large scales but scattered with local gentle slopes. Cloddy soil sticking on its wheels implies a greater cohesion of the lunar soil than encountered at other lunar landing sites. Further identification results indicate that the regolith resembles dry sand and sandy loam on Earth in bearing properties, demonstrating greater bearing strength than that identified during the Apollo missions. In sharp contrast to the sparsity of rocks along the traverse route, small fresh craters with unilateral moldable ejecta are abundant, and some of them contain high-reflectance materials at the bottom, suggestive of secondary impact events. These findings hint at notable differences in the surface geology between the lunar farside and nearside. Experience gained with Yutu-2 improves the understanding of the farside of the Moon, which, in return, may lead to locomotion with improved efficiency and larger range.

Abstract
The strong absorption and reflection from atomically thin graphene nanoribbons has been demonstrated over the past decade. However, due to the significant band dispersion of graphene nanoribbons, the angle of incident wave has remained limited to a very narrow range. Obtaining strong absorption and reflection with a wide range of incident angles from atomically thin graphene layers has remained an unsolvable problem. Here, we construct a tunable moiré superlattice composed of a pair of graphene nanoribbon arrays to achieve this goal. By designing the interlayer coupling between two graphene nanoribbon arrays with mismatched periods, the moiré flat bands and the localization of their eigen-fields was realized. Based on the moiré flat bands of graphene nanoribbons, highly efficient reflection and nearly perfect absorption was achieved with a wide range of incident angles. Even more interesting, is how these novel phenomena can be tuned through the adjustment of the graphene's Fermi energy, either electrostatically or chemically. Our designed moiré graphene nanoribbons suggest a promising platform to engineer moiré physics with tunable behaviors, and may have potential applications in the field of wide-angle absorbers and reflectors in the mid-infrared region.

Abstract
BACKGROUND C-reactive protein (CRP), a biomarker of inflammation, is highly expressed in osteoarthritis- (OA-) related diseases, but its exact role remains unknown. In this study, we evaluated the biological effect of CRP on temporomandibular joint (TMJ) inflammation. METHODS Freund's complete adjuvant (CFA) was used to induce TMJ inflammation in CRP-knockout (CRP-/-) and control rats. Degenerative changes in the TMJ were compared to elucidate the role of CRP in TMJ inflammation. In addition, inflammatory cytokines, macrophage activation, and osteoclast differentiation were evaluated by real-time quantitative polymerase chain reaction, immunohistochemistry, and tartrate-resistant phosphatase staining to explore the potential regulatory mechanism. RESULTS Compared to the control, CFA induced TMJ inflammation, which increased systemic and local CRP expression. Furthermore, CRP-/- rats exhibited less severe inflammatory symptoms. The downregulation of proinflammatory cytokines (interleukin- (IL-) 1β and IL-6) and upregulation of the anti-inflammatory cytokine IL-10 were detected in CRP-/- rats, which also exhibited reduced macrophage activation and osteoclast differentiation. CONCLUSION These results indicated that controlling the highly elevated levels of CRP during inflammation could modify the cytokine profile, macrophage activation, and osteoclast differentiation, thus, providing beneficial effects for TMJ-OA prevention and treatment.

Abstract
Insufficient cardiorespiratory compensation is closely associated with acute hypoxic symptoms and high-altitude (HA) cardiovascular events. To avoid such adverse events, predicting HA cardiorespiratory fitness impairment (HA-CRFi) is clinically important. However, to date, there is insufficient information regarding the prediction of HA-CRFi. In this study, we aimed to formulate a protocol to predict individuals at risk of HA-CRFi. We recruited 246 volunteers who were transported to Lhasa (HA, 3,700 m) from Chengdu (the sea level [SL], <500 m) through an airplane. Physiological parameters at rest and during post-submaximal exercise, as well as cardiorespiratory fitness at HA and SL, were measured. Logistic regression and receiver operating characteristic (ROC) curve analyses were employed to predict HA-CRFi. We analyzed 66 pulmonary vascular function and hypoxia-inducible factor- (HIF-) related polymorphisms associated with HA-CRFi. To increase the prediction accuracy, we used a combination model including physiological parameters and genetic information to predict HA-CRFi. The oxygen saturation (SpO2) of post-submaximal exercise at SL and EPAS1 rs13419896-A and EGLN1 rs508618-G variants were associated with HA-CRFi (SpO2, area under the curve (AUC) = 0.736, cutoff = 95.5%, p < 0.001; EPAS1 A and EGLN1 G, odds ratio [OR] = 12.02, 95% CI = 4.84–29.85, p < 0.001). A combination model including the two risk factors—post-submaximal exercise SpO2 at SL of <95.5% and the presence of EPAS1 rs13419896-A and EGLN1 rs508618-G variants—was significantly more effective and accurate in predicting HA-CRFi (OR = 19.62, 95% CI = 6.42–59.94, p < 0.001). Our study employed a combination of genetic information and the physiological parameters of post-submaximal exercise at SL to predict HA-CRFi. Based on the optimized prediction model, our findings could identify individuals at a high risk of HA-CRFi in an early stage and reduce cardiovascular events.

Abstract
IMPORTANCE Prevention of chemotherapy-induced neutropenia (CIN) and its clinical consequences is an unmet need for which plinabulin, a selective immunomodulating microtubule-binding agent, is being tested. OBJECTIVE To demonstrate noninferiority between plinabulin and pegfilgrastim for days of severe neutropenia in cycle 1 in patients with solid tumors treated with docetaxel. DESIGN, SETTING, AND PARTICIPANTS The Plinabulin vs Pegfilgrastim for the Prevention of Docetaxel-Induced Neutropenia in Patients With Solid Tumors (PROTECTIVE-1) double-blind phase 3 randomized clinical trial was performed in multiple centers in China, Russia, Ukraine, and the US. Participants included patients with breast, prostate, or non-small cell lung cancer treated with single-agent docetaxel chemotherapy. Data were collected from June 1, 2018, to January 31, 2019. The database was locked on February 18, 2021. Data analysis was based on intention to treat and safety and performed from October 5, 2018, to February 23, 2021. INTERVENTIONS Plinabulin, 40 mg, plus placebo or pegfilgrastim, 6 mg, plus placebo. MAIN OUTCOMES AND MEASURES The primary end point was day of severe neutropenia in cycle 1. Additional end points included clinical consequences of CIN (febrile neutropenia, hospitalizations, infections, antibiotic use, and modifications of chemotherapy dose), patient-reported outcomes for bone pain score, markers for immune suppression (neutrophil-to-lymphocyte ratio [NLR] of >5), immature neutrophils (band, promyelocyte, and myelocyte counts >0), and safety. RESULTS Among the 105 patients included in the analysis (65 [6.19%] women; median age, 59 [range, 31-81] years), the primary end point was met within a noninferiority margin of 0.65 days, with a mean difference of 0.52 days (98.52% CI, 0.40-0.65 days). Grade 4 neutropenia frequency in cycle 1 was not significantly different. Plinabulin had earlier onset of action with less grade 4 neutropenia in week 1 of cycle 1. Plinabulin had fewer adverse clinical consequences with rates of febrile neutropenia (0 of 52 vs 1 of 53 [1.9%]), infections (4 of 52 [7.7%] vs 8 of 53 [15.1%]), chemotherapy dose delay of more than 7 days (2 of 52 [3.8%] vs 3 of 53 [5.7%]), and permanent chemotherapy discontinuation (7 of 52 [13.5%] vs 14 of 53 [26.4%]). Patients receiving plinabulin had significantly less bone pain (difference, -0.67 [95% CI, -1.17 to -0.16]; P = .01) and a better immunosuppressive profile (NLR >5 at day 8, 2 of 52 [3.8%] vs 24 of 51 [46.0%]; P < .001). Plinabulin was well tolerated, with comparable safety to pegfilgrastim. CONCLUSIONS AND RELEVANCE Plinabulin has comparable efficacy to pegfilgrastim for the prevention of CIN, with better safety and a better immunosuppressive profile. Plinabulin's same-day dosing compared with pegfilgrastim's next-day dosing offers distinct advantages, including reducing use of health care services.

Abstract
Background: Acute high altitude (HA) exposure results in blood pressure (BP) variations in most subjects. Previous studies have demonstrated that higher BP is potentially correlated with acute mountain sickness (AMS). The BP load may be of clinical significance regarding systemic circulation status. Objectives: This study aimed to examine HA-induced BP changes in patients with AMS compared to those in healthy subjects. Further, we provided clinical information about the relationship between variations in 24-h ambulatory parameters (BP level, BP variability, and BP load) and AMS. Methods: Sixty-nine subjects were enrolled and all participants ascended Litang (4,100 m above sea level). They were monitored using a 24-h ambulatory blood pressure device and underwent echocardiography within 24 h of altitude exposure. The 2018 Lake Louise questionnaire was used to evaluate AMS. Results: The AMS group comprised more women than men [15 (65.2%) vs. 13 (28.3%), P < 0.001] and fewer smokers [4 (17.4%) vs. 23 (50.0%), P = 0.009]. The AMS group exhibited significant increases in 24-h BP compared to the non-AMS group (24-h SBP variation: 10.52 ± 6.48 vs. 6.03 ± 9.27 mmHg, P = 0.041; 24-h DBP variation: 8.70 ± 4.57 vs. 5.03 ± 4.98 mmHg, P = 0.004). The variation of mean 24-h cBPL (cumulative BP load) (mean 24-h cSBPL: 10.58 ± 10.99 vs. 4.02 ± 10.58, P = 0.016; 24-h mean cDBPL: 6.03 ± 5.87 vs. 2.89 ± 4.99, P = 0.034) was also obviously higher in AMS subjects than in non-AMS subjects after HA exposure. 24-h mean cSBPL variation (OR = 1.07, P = 0.024) and 24-h mean cDBPL variation (OR = 1.14, P = 0.034) were independent risk factors of AMS. Moreover, variation of 24-h mean cSBPL showed a good correlation with AMS score (R = 0.504, P < 0.001). Conclusions: Our study demonstrated that patients with AMS had higher BP and BP load changes after altitude exposure than healthy subjects. Excessive BP load variations were associated with AMS. Thus, BP load could be an effective indicator regarding systemic circulation status of AMS.

Abstract
Heavy metals are both integral parts of cells and environmental toxicants, and their deregulation is associated with severe cellular dysfunction and various diseases. Here we show that the Hippo pathway plays a critical role in regulating heavy metal homeostasis. Hippo signalling deficiency promotes the transcription of heavy metal response genes and protects cells from heavy metal-induced toxicity, a process independent of its classic downstream effectors YAP and TAZ. Mechanistically, the Hippo pathway kinase LATS phosphorylates and inhibits MTF1, an essential transcription factor in the heavy metal response, resulting in the loss of heavy metal response gene transcription and cellular protection. Moreover, LATS activity is inhibited following heavy metal treatment, where accumulated zinc directly binds and inhibits LATS. Together, our study reveals an interplay between the Hippo pathway and heavy metals, providing insights into this growth-related pathway in tissue homeostasis and stress response.
