Abstract
Objective: To explore the biological process of liver tissue-derived extracellular vesicle (LT-EV) in promoting osteogenic differentiation of mesenchymal stem cells and healing of jaw defects to provide a feasible treatment method for the clinical treatment of jaw bone defects. Methods: Enzymatic hydrolysis and differential centrifugation were used to extract LT-EV, scanning electron microscopy, Western blotting, and nanoparticle tracking analyzers were used to identify and characterize LT-EV, and further to explore the biological functions of LT-EV through proteomics and Kyoto Encyclopedia of Genes and Genomes. Flow cytometry was used to detect LT-EV plasma concentration and to calculate the plasma half-life of LT-EV. Small animal in vivo imaging system was used to detect the biological distribution of LT-EV 24 hours after injection. Six C57BL/6 mice were divided into control group and LT-EV group (3 mice in each group) by simple random sampling method. All mice underwent jaw bone defect surgery and tail vein injection every 7 days (the control group was injected with phosphoric buffer saline, LT-EV group was injected with LT-EV), micro-CT was used to evaluate the degree of mouse jaw bone healing 28 days after surgery, HE staining was used to analyze the multi-organ biosafety of LT-EV, and immunofluorescence staining was used to detect the jaw bone expression of osteogenic marker proteins in the defect area. Human jaw bone mesenchymal stem cells (hJBMSC) induced by osteogenic differentiation were treated with LT-EV (obtained from orthognathic surgery patients provided by the Department of Traumatology and Orthognathic Surgery of the Third Affiliated Hospital of Air Force Medical University resected normal jaw bone fragments), and the difference in osteogenic differentiation ability between the hJBMSC group and the control group (phosphate buffer saline treatment) was compared, and the in vitro bone differentiation promoting effect of LT-EV was verified through alkaline phosphatase (ALP) staining and real-time quantitative PCR (qRT-PCR). Results: The yield of LT-EV was high, and proteomics and Kyoto Encyclopedia of Genes and Genomes showed that LT-EV contained a series of proteins that regulated cell biological functions. LT-EV injected into the tail vein could reach the mouse jaw bone defect area and promote the regeneration and repair of the jaw bone defect [the bone volume fractions of the LT-EV group and the control group were (36.06±4.20)% and (18.58±5.61)%, respectively; t=4.32, P=0.013], and had good biosafety. LT-EV could promote osteogenic differentiation of hJBMSC in vitro. Compared to the control group, ALP staining and osteogenic gene expression levels were significantly enhanced after osteogenic differentiation of hJBMSC (P<0.05). Conclusions: LT-EV exhibits a high yield, ease of acquisition, high biological safety, and excellent bone-promoting effects. It holds promise as a novel cell-free therapy strategy for regenerating craniofacial bone defects.

Abstract
PURPOSE Oxidative balance stress (OBS) was an important indicator for assessing exposure to oxidative stress related to diet and lifestyle. The purpose of this study was to explore the relationship between OBS and kidney stone disease (KSD). METHODS Secondary dataset analysis was performed by the study from six survey cycles (2007-2018) in the National Health and Nutrition Examination Survey (NHANES). OBS was the exposure factor and ever had kidney stone (yes or no) was the outcome. Weighted univariate or multivariate logistic regression models were used to estimate the associations. RESULTS The prevalence of KSD among participants was 8.6%. OBS showed a significant negative correlation with KSD (OR: 0.98, 95% CI 0.96-0.999), 35% reduction in KSD in the highest OBS quartile compared to the lowest OBS quartile. Dietary OBS was significantly negatively correlated with KSD (OR: 0.98, 95% CI 0.96-0.9998), but not with lifestyle OBS. In addition, OBS had a negative correlation with KSD in females (OR: 0.97, 95% CI 0.94-0.996), non-diabetic participants (OR: 0.98, 95% CI 0.96-0.99), and hypertensive participants (OR: 0.96, 95% CI 0.93-0.99), but OBS was not observed to be associated with KSD in gout participants. Interestingly, this relationship existed in participants aged 30-60 years and a ratio of family income to poverty (PIR) of 1.3-3.5 (all P value < 0.05). CONCLUSION Our study revealed that OBS was negative associated with KSD, and high OBS might be a protective factor in KSD. Targeting one of the components of OBS might be beneficial.

Abstract
BACKGROUND Extant research has demonstrated a correlation between exposure to polycyclic aromatic hydrocarbons (PAHs) and impaired lung function. The maintenance of an antioxidant-rich diet/lifestyle positively benefits pulmonary health. However, the potential ameliorative impact of an antioxidant-based diet/lifestyle on PAH-induced detrimental effects remains unclear. METHODS The study drew upon cross-sectional data encompassing 1615 participants derived from the National Health and Nutrition Examination Survey 2007 to 2012. To gauge the maintenance of an antioxidant-rich diet/lifestyle, we employed Oxidative Balance Score (OBS) that incorporates sixteen nutrients and four lifestyle factors. Lung function was evaluated using percent-predicted Forced Vital Capacity (FVC), Forced Expiratory Volume 1st Second (FEV1), FEV1/FVC, and fractional exhaled nitric oxide (FENO). Our analytical approach entailed the utilization of weighted linear models. RESULTS Our analysis unveiled interaction effects between urinary monohydroxy polycyclic aromatic hydrocarbons (OH-PAHs) and OBS concerning lung function. A one-unit increase in ∑OH-PAH (sum of eight OH-PAHs) was linked to a -0.75% reduction (95% CI: -1.28, -0.22) in FEV1/FVC. Individuals exhibiting low OBS displayed a marked decrease in FEV1/FVC (mean difference = -1.10%; 95% CI: -1.82, -0.39) for each unit increase in ∑OH-PAH, whereas no significant associations were discerned for those with medium or high OBS. Further stratification by gender yielded consistent results. The correlation between ∑OH-PAH and FENO proved statistically significant among participants with low OBS (P = 0.002) and medium OBS (P = 0.001), but non-significant for those with high OBS. Parallel findings emerged when examining percent-predicted FEV1 and FVC. CONCLUSIONS In conclusion, our study underscores the existence of statistically significant interactions between OH-PAHs and the maintenance of an antioxidant-rich diet and lifestyle concerning lung function. These findings underscore the pivotal role of maintaining an antioxidant-based diet and lifestyle in mitigating the adverse impacts of PAH exposure on lung function.

Abstract
Oats (Avena sativa) are an important cereal crop and cool-season forage worldwide. Heat shock protein 90 (HSP90) is a protein ubiquitously expressed in response to heat stress in almost all plants. To date, the HSP90 gene family has not been comprehensively reported in oats. Herein, we have identified twenty HSP90 genes in oats and elucidated their evolutionary pathways and responses to five abiotic stresses. The gene structure and motif analyses demonstrated consistency across the phylogenetic tree branches, and the groups exhibited relative structural conservation. Additionally, we identified ten pairs of segmentally duplicated genes in oats. Interspecies synteny analysis and orthologous gene identification indicated that oats share a significant number of orthologous genes with their ancestral species; this implies that the expansion of the oat HSP90 gene family may have occurred through oat polyploidization and large fragment duplication. The analysis of cis-acting elements revealed their influential role in the expression pattern of HSP90 genes under abiotic stresses. Analysis of oat gene expression under high-temperature, salt, cadmium (Cd), polyethylene glycol (PEG), and abscisic acid (ABA) stresses demonstrated that most AsHSP90 genes were significantly up-regulated by heat stress, particularly AsHSP90-7, AsHSP90-8, and AsHSP90-9. This study offers new insights into the amplification and evolutionary processes of the AsHSP90 protein, as well as its potential role in response to abiotic stresses. Furthermore, it lays the groundwork for understanding oat adaptation to abiotic stress, contributing to research and applications in plant breeding.

Abstract
BACKGROUND Currently, there remains insufficient focus on non-severe community-acquired pneumonia (CAP) patients who are at risk of clinical deterioration, and there is also a dearth of research on the related risk factors. Early recognition of hospitalized patients at risk of clinical deterioration will be beneficial for their clinical management. METHOD A retrospective study was conducted in The First Affiliated Hospital of Wenzhou Medical University, China, spanning from January 1, 2018 to April 30, 2022, and involving a total of 1,632 non-severe CAP patients. Based on whether their condition worsened within 72 h of admission, patients were divided into a clinical deterioration group and a non-clinical deterioration group. Additionally, all patients were randomly assigned to a training set containing 75% of patients and a validation set containing 25% of patients. In the training set, risk factors for clinical deterioration in patients with non-severe CAP were identified by using LASSO regression analysis and multivariate logistic regression analysis. A nomogram was developed based on identified risk factors. The effectiveness of the nomogram in both the training and validation sets was assessed using Receiver Operating Characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). RESULTS Age, body mass index (BMI), body temperature, cardiovascular comorbidity, respiratory rate, LDH level, lymphocyte count and D-dimer level were identified as risk factors associated with the clinical deterioration of non-severe CAP within 72 h of admission. The area under curve (AUC) value of the nomogram was 0.78 (95% CI: 0.74-0.82) in the training set and 0.75 (95% CI: 0.67-0.83) in the validation set. Furthermore, the calibration curves for both the training and validation sets indicated that the predicted probability of clinical deterioration aligned with the actual probability. Additionally, DCA revealed clinical utility for the nomogram at a specific threshold probability. CONCLUSION The study successfully identified the risk factors linked to the clinical deterioration of non-severe CAP and constructed a nomogram for predicting the probability of deterioration. The nomogram demonstrated favorable predictive performance and has the potential to aid in the early identification and management of non-severe CAP patients at elevated risk of deterioration.

Abstract
Background The oxidative balance score (OBS), an encompassing scoring mechanism for assessing oxidative stress, is formulated based on nutritional and lifestyle components. The emergence of metabolic syndrome (MetS) is intricately linked to oxidative stress. Nonetheless, the correlation between OBS and MetS displays variability within distinct cohorts. Objective We worked on the relationships between OBS and the risk of MetS, MetS severity, and all-cause mortality of MetS patients. Methods A total of 11,171 adult participants were collected from the U.S. National Health Examination Survey (NHANES) 2007-2018. Employing survey-weighted logistic models, we evaluated the relationship between OBS and MetS risk. Furthermore, survey-weighted linear models were utilized to investigate the connection between OBS and MetS severity. Among the participants, 3,621 individuals had their survival status recorded, allowing us to employ Cox proportional hazards regression models in order to ascertain the association between OBS and the all-cause mortality within the subset of individuals with MetS. The OBS (where a higher OBS signified an increased prevalence of anti- or pro-oxidant exposures) weighed the 20 factors, while the MetS severity score weighed the five factors. Results After multivariable adjustment, individuals with elevated OBS were found to exhibit a decreased susceptibility to MetS [odds ratio (OR) 0.95; 95% CI 0.94-0.96]. The adjusted OR was 0.42 (95% CI 0.33-0.53) for MetS risk in the fourth OBS quartile compared with those in the first OBS quartile (P for trend < 0.001). A one-unit increase in OBS was linked to a 3% reduction in MetS severity score by 3% (mean difference, -0.03; 95% CI, -0.04 to -0.03). Moreover, increased OBS correlated with decreased hazard of all-cause mortality risk among MetS subjects (adjusted hazard ratio, 0.95; 95% CI, 0.93-0.98). These associations retained their strength even subsequent to the introduction of sensitivity analyses. There existed a statistically significant negative correlation between diet/lifestyle OBS and both MetS risk as well as MetS severity. Conclusions An inverse correlation was observed between OBS and the susceptibility to MetS, MetS severity, and all-cause mortality of MetS patients. Health outcomes for MetS patients were positively related to antioxidant diets and lifestyles.

Abstract
Gastric cancer (GC) is a prevalent form of cancer, with Helicobacter pylori (H. pylori) infection being the most common risk factor. Recent studies have highlighted the role of long-term irritation of the gastric mucosa caused by bile reflux in the development of cancer. Bile acids (BAs), which are a significant component in bile reflux, have the potential to promote gastric carcinogenesis through various mechanisms. These mechanisms include the induction of intestinal metaplasia (IM), inhibition of H. pylori activity, modification of H. pylori colonization, and alteration of the abundance and composition of microorganisms in the stomach. Defining the mechanism of bile acid-induced gastric carcinogenesis could potentially be an effective approach to prevent GC. Hence, this paper aims to review the mechanism of bile acid-induced IM, the association between BAs and H. pylori infection as well as microorganisms in the stomach, and the correlation between BAs and gastric carcinogenesis. The ultimate goal is to elucidate the role of BAs in the development of GC.

Abstract
BACKGROUND Although rectal mucinous adenocarcinoma (RMC) is less sensitive to radiotherapy, adjuvant radiotherapy is still recommended for RMC patients. This study aimed to explore whether adjuvant radiotherapy is necessary for stage III RMC. METHODS Data of patients with stage III RMC were obtained from the National Cancer Institute's SEER database (2004-2015). The survival rates were calculated by Kaplan-Meier method and compared by log-rank test. Univariate and multivariate Cox regression analyses were used to assess the impact of clinicopathological parameters on overall survival (OS) and cancer-specific survival (CSS). RESULTS RMC has a worse T and N stage at diagnosis than rectal adenomatous carcinoma (RAC) (all p < 0.001). Multivariate Cox regression analyses revealed that histopathological type MC was an independent poor prognostic factor for OS (HR 1.27; 95%CI 1.14-1.41; p < 0.001) and CSS (HR 1.34; 95%CI 1.18-1.51; p < 0.001). Subgroup analysis based on different treatment regimens showed no significant difference between chemotherapy group and chemotherapy plus radiotherapy group. After the propensity score matching, no significant difference was also found in OS and CSS between chemotherapy group and chemotherapy plus radiotherapy group. CONCLUSIONS RMC is an independent poor prognostic factor for OS and CSS. Adjuvant radiotherapy for RMC was not beneficial in improving survival outcomes.

Abstract
The prevalence of dyslipidemia is increased in postmenopausal women due to dysregulation of lipid metabolism and deficiency of estrogen levels. At the same time, some postmenopausal women also have menopausal syndromes such as vasomotor symptoms, physical physiology, mental psychology, and urogenital tract atrophy. Menopausal hormone therapy is the most effective measure to alleviate menopausal syndrome. And initiating MHT in early menopause can reduce cardiovascular damage. However, menopausal hormone therapy can also bring the risk of thromboembolic diseases such as venous embolism, myocardial infarction and stroke. Different drug regimens have different effects on lipid metabolism. Women with menopausal syndrome should take individualized treatment plans for different types of dyslipidemia. Therefore, this article reviews the management and treatment of menopausal syndrome in women with dyslipidemia, so as to provide a reference for personalized management of dyslipidemia in postmenopausal women.

Abstract
BACKGROUND Oxidative stress is correlated with sleep quality. A common tool for evaluating dietary and lifestyle exposures to oxidative stress is the Oxidative Balance Score (OBS), with higher OBS suggesting more substantial antioxidant exposures. The relationship between OBS and sleep quality is unclear. Investigating the association between OBS and sleep quality was the purpose of this study. METHODS To figure out the relationship between OBS and sleep quality, we utilized weighted linear models and weighted logistic regression. Adjusted models were also examined. RESULTS 6300 participants who took part in the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2014 were recruited. OBS was negatively associated with sleep disorder (OR: 0.97; 95 % CI: 0.94-0.99), and positively associated with sleep duration (MD: 0.02; 95%CI: 0.01-0.03). Within the range of OBS > 24, each unit increase in OBS will result in a 40 % reduction in sleep disorder, and a 26 % increasement in sleep duration after adjustment (all P for trend <0.05). Dietary and lifestyle components were closely related to sleep quality independently. The relationship between OBS and sleep quality was prominent in the female population under 50 years of age. After stratification by education level, this relationship persisted. LIMITATION This research was cross-sectional design, and it was not possible to deduce causality. CONCLUSION Diet and lifestyle might influence sleep quality by modulating oxidative balance. Antioxidant diets and lifestyles were important in reducing sleep problems and our study also provided new ideas for improving sleep quality.

Abstract
Reed canary grass (Phalaris arundinacea L.) is known for its tolerance to drought, heavy metals, and waterlogging, making it a popular choice for forage production and wetland restoration in the Qinghai-Tibet Plateau (QTP). To accurately assess gene expression in reed canary grass under different abiotic stresses, suitable reference genes need to be identified and validated. Thirteen candidate reference gene sequences were selected and screened using RT-qPCR to detect their expression levels in reed canary grass leaves under drought, salt, cadmium, and waterlogging stresses. Four algorithms were used to assess the stability of the expression levels of the candidate reference genes. The most stably expressed genes were UBC and H3 under drought Cd, ETF and CYT under salt stress, and ETF and TUB under waterlogging stress. GAPDH was found to be less stable under abiotic stresses. PIP-1, PAL, NAC 90, and WRKY 72A were selected as response genes for quantitative expression assessment under drought, salt, Cd, and waterlogging stresses to confirm the accuracy of the selected stable reference genes. These results provide a theoretical reference for assessing gene expression in reed canary grass under abiotic stresses.

Abstract
Acute lung injury (ALI) is associated with an increased incidence of respiratory diseases, which are devastating clinical disorders with high global mortality and morbidity. Evidence confirms that fibroblast growth factors (FGFs) play key roles in mediating ALI. Mice were treated with LPS (lipopolysaccharide: 5 mg/kg, intratracheally) to establish an in vivo ALI model. Human lung epithelial BEAS-2B cells cultured in a corresponding medium with LPS were used to mimic the ALI model in vitro. In this study, we characterized FGF10 pretreatment (5 mg/kg, intratracheally) which improved LPS-induced ALI, including histopathological changes, and reduced pulmonary edema. At the cellular level, FGF10 pretreatment (10 ng/mL) alleviated LPS-induced ALI accompanied by reduced reactive oxygen species (ROS) accumulation and inflammatory responses, such as IL-1β, IL-6, and IL-10, as well as suppressed excessive autophagy. Additionally, immunoblotting and co-immunoprecipitation showed that FGF10 activated nuclear factor erythroid-2-related factor 2 (Nrf2) signaling pathway via Nrf2 nuclear translocation by promoting the interaction between p62 and keap1, thereby preventing LPS-induced ALI. Nrf2 knockout significantly reversed these protective effects of FGF10. Together, FGF10 protects against LPS-induced ALI by restraining autophagy via p62-Kelch-like ECH-associated protein 1 (Keap1)-Nrf2 signaling pathway, implying that FGF10 could be a novel therapy for ALI.

Abstract
Hordeum L. is widely distributed in mountain or plateau of subtropical and warm temperate regions around the world. Three wild perennial Hordeum species, including H. bogdanii, H. brevisubulatum, and H. violaceum, have been used as forage and for grassland ecological restoration in high-altitude areas in recent years. To date, the degree of interspecies sequence variation in the three Hordeum species within existing gene pools is still not well-defined. Herein, we sequenced and assembled chloroplast (cp) genomes of the three species. The results revealed that the cp genome of H. bogdanii showed certain sequence variations compared with the cp genomes of the other two species (H. brevisubulatum and H. violaceum), and the latter two were characterized by a higher relative affinity. Parity rule 2 plot (PR2) analysis illuminated that most genes of all ten Hordeum species were concentrated in nucleotide T and G. Numerous single nucleotide polymorphism (SNP) and insertion/deletion (In/Del) events were detected in the three Hordeum species. A series of hotspots regions (tRNA-GGU ~ tRNA-GCA, tRNA-UGU ~ ndhJ, psbE ~ rps18, ndhF ~ tRNA-UAG, etc.) were identified by mVISTA procedures, and the five highly polymorphic genes (tRNA-UGC, tRNA-UAA, tRNA-UUU, tRNA-UAC, and ndhA) were proved by the nucleotide diversity (Pi). Although the distribution and existence of cp simple sequence repeats (cpSSRs) were predicted in the three Hordeum cp genomes, no rearrangement was found between them. A similar phenomenon has been found in the cp genome of the other seven Hordeum species, which has been published so far. In addition, evolutionary relationships were reappraised based on the currently reported cp genome of Hordeum L. This study offers a framework for gaining a better understanding of the evolutionary history of Hordeum species through the re-examination of their cp genomes, and by identifying highly polymorphic genes and hotspot regions that could provide important insights into the genetic diversity and differentiation of these species.

Abstract
BACKGROUND The tumour microenvironment consists of a complex and dynamic milieu of cancer cells, including tumour-associated stromal cells (leukocytes, fibroblasts, vascular cells, etc.) and their extracellular products. During invasion and metastasis, cancer cells actively remodel the tumour microenvironment and alterations of microenvironment, particularly cancer-associated fibroblasts (CAFs), can promote tumour progression. However, the underlying mechanisms of the CAF formation and their metastasis-promoting functions remain unclear. METHODS Primary liver fibroblasts and CAFs were isolated and characterized. CAFs in clinical samples were identified by immunohistochemical staining and the clinical significance of CAFs was also analysed in two independent cohorts. A transwell coculture system was used to confirm the role of HCC cells in CAF recruitment and activation. qRT-PCR, western blotting and ELISA were used to screen paracrine cytokines. The role and mechanism of Egfl7 in CAFs were explored via an in vitro coculture system and an in vivo mouse orthotopic transplantation model. RESULTS We showed that CAFs in hepatocellular carcinoma (HCC) are characterized by the expression of α-SMA and that HCC cells can recruit liver fibroblasts (LFs) and activate them to promote their transformation into CAFs. High α-SMA expression, indicating high CAF infiltration, was correlated with malignant characteristics. It was also an independent risk factor for HCC survival and could predict a poor prognosis in HCC patients. Then, we demonstrated that EGF-like domain multiple 7 (Egfl7) was preferentially secreted by HCC cells, and exhibited high potential to recruit and activate LFs into the CAF phenotype. The ability of Egfl7 to modulate LFs relies upon increased phosphorylation of FAK and AKT via the receptor ανβ3 integrin. Strikingly, CAFs activated by paracrine Egfl7 could further remodel the tumour microenvironment by depositing fibrils and collagen and in turn facilitate HCC cell proliferation, invasion and metastasis. CONCLUSION Our data highlighted a novel role of Egfl7 in remodelling the tumour microenvironment: it recruits LFs and activates them to promote their transformation into CAFs via the ανβ3 integrin signaling pathway, which further promotes HCC progression and contributes to poor clinical outcomes in HCC patients.

Abstract
Drought is one of the most significant limiting factors affecting plant growth and development on the Qinghai-Tibet Plateau (QTP). Mining the drought-tolerant genes of the endemic perennial grass of the QTP, Siberian wildrye (Elymus sibiricus), is of great significance to creating new drought-resistant varieties which can be used in the development of grassland livestock and restoring natural grassland projects in the QTP. To investigate the transcriptomic responsiveness of E. sibiricus to drought stress, PEG-induced short- and long-term drought stress was applied to two Siberian wildrye genotypes (drought-tolerant and drought-sensitive accessions), followed by third- and second-generation transcriptome sequencing analysis. A total of 40,708 isoforms were detected, of which 10,659 differentially expressed genes (DEGs) were common to both genotypes. There were 2107 and 2498 unique DEGs in the drought-tolerant and drought-sensitive genotypes, respectively. Additionally, 2798 and 1850 DEGs were identified in the drought-tolerant genotype only under short- and long-term conditions, respectively. DEGs numbering 1641 and 1330 were identified in the drought-sensitive genotype only under short- and long-term conditions, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that all the DEGs responding to drought stress in E. sibiricus were mainly associated with the mitogen-activated protein kinase (MAKP) signaling pathway, plant hormone signal transduction, the linoleic acid metabolism pathway, the ribosome pathway, and plant circadian rhythms. In addition, Nitrate transporter 1/Peptide transporter family protein 3.1 (NPF3.1) and Auxin/Indole-3-Acetic Acid (Aux/IAA) family protein 31(IAA31) also played an important role in helping E. sibiricus resist drought. This study used transcriptomics to investigate how E. sibiricus responds to drought stress, and may provide genetic resources and references for research into the molecular mechanisms of drought resistance in native perennial grasses and for breeding drought-tolerant varieties.

Abstract
Background The morbidity and mortality of young-onset colorectal cancer (YO-CRC) patients have been increasing in recent years. Moreover, YO-CRC patients with synchronous liver-only metastases (YO-CRCSLM) have various survival outcomes. Therefore, the purpose of this study was to construct and validate a prognostic nomogram for patients with YO-CRCSLM. Methods The YO-CRCSLM patients were rigorously screened from the Surveillance, Epidemiology, and End Results (SEER) database in January 2010 and December 2018 and then assigned to a training and validation cohort randomly (1488 and 639 patients, respectively). Moreover, the 122 YO-CRCSLM patients who were enrolled in The First Affiliated Hospital of Nanchang University were served as a testing cohort. The variables were selected using the multivariable Cox model based on the training cohort and then developed a nomogram. The validation and testing cohort were used to validate the model's predictive accuracy. The calibration plots were used to determine the Nomogram's discriminative capabilities and precision, and the decision analysis (DCA) was performed to evaluate the Nomogram's net benefit. Finally, the Kaplan-Meier survival analyses were performed for the stratified patients based on total nomogram scores classified by the X-tile software. Results The Nomogram was constructed including ten variables: marital status, primary site, grade, metastatic lymph nodes ratio (LNR), T stage, N stage, carcinoembryonic antigen (CEA), Surgery, and chemotherapy. The Nomogram performed admirably in the validation and testing group according to the calibration curves. The DCA analyses showed good clinical utility values. Low-risk patients (score<234) had significantly better survival outcomes than middle-risk (234-318) and high-risk (>318) patients (P < 0.001). Conclusion A nomogram predicting the survival outcomes for patients with YO-CRCSLM was developed. In addition to facilitating personalized survival prediction, this nomogram may assist in developing clinical treatment strategies for patients with YO-CRCSLM who are undergoing treatment.

Abstract
Galega orientalis, a leguminous herb in the Fabaceae family, is an ecologically and economically important species widely cultivated for its strong stress resistance and high protein content. However, genomic information of Galega orientalis has not been reported, which limiting its evolutionary analysis. The small genome size makes chloroplast relatively easy to obtain genomic sequence for phylogenetic studies and molecular marker development. Here, the chloroplast genome of Galega orientalis was sequenced and annotated. The results showed that the chloroplast genome of G. orientalis is 125,280 bp in length with GC content of 34.11%. A total of 107 genes were identified, including 74 protein-coding genes, 29 tRNAs and four rRNAs. One inverted repeat (IR) region was lost in the chloroplast genome of G. orientalis. In addition, five genes (rpl22, ycf2, rps16, trnE-UUC and pbf1) were lost compared with the chloroplast genome of its related species G. officinalis. A total of 84 long repeats and 68 simple sequence repeats were detected, which could be used as potential markers in the genetic studies of G. orientalis and related species. We found that the Ka/Ks values of three genes petL, rpl20, and ycf4 were higher than one in the pairwise comparation of G. officinalis and other three Galegeae species (Calophaca sinica, Caragana jubata, Caragana korshinskii), which indicated those three genes were under positive selection. A comparative genomic analysis of 15 Galegeae species showed that most conserved non-coding sequence regions and two genic regions (ycf1 and clpP) were highly divergent, which could be used as DNA barcodes for rapid and accurate species identification. Phylogenetic trees constructed based on the ycf1 and clpP genes confirmed the evolutionary relationships among Galegeae species. In addition, among the 15 Galegeae species analyzed, Galega orientalis had a unique 30-bp intron in the ycf1 gene and Tibetia liangshanensis lacked two introns in the clpP gene, which is contrary to existing conclusion that only Glycyrrhiza species in the IR lacking clade (IRLC) lack two introns. In conclusion, for the first time, the complete chloroplast genome of G. orientalis was determined and annotated, which could provide insights into the unsolved evolutionary relationships within the genus Galegeae.

Abstract
Background Awake prone positioning has been used for non-intubated patients with COVID-19-related acute hypoxaemic respiratory failure, but the results are contradictory. We aimed to highlight the role of awake prone positioning combined with high-flow nasal oxygen therapy in severe COVID-19 patients infected with the Delta variant of SARS-CoV-2. Methods From June 12 to December 7, 2021, we successfully performed prone position(PP) combined with high-flow nasal oxygen(HFNO) therapy on two patients infected with the delta variant of SARS-CoV-2. HFNO was prescribed to reach SpO2 ≥ 92%. PP was proposed to patients with PaO2/FiO2(P/F) < 150 mmHg. Arterial blood gas (ABG) and hemodynamic were monitored before and after PP sessions. The target time of PP was more than 12 h per day and could be appropriately shortened according to the patient's tolerance. Relevant clinical data, HFNO parameters, PICCO parameters, P/F ratio and PP duration were obtained from medical records. Results A total of 23 PP sessions and 6 PP sessions combined with HFNO were performed in case 1 and case 2, respectively. Compared with values before PP, GEDI, ELWI and Qs/Qt decreased significantly (GEDI: 869.50 ± 60.50 ml/m2 vs. 756.86 ± 88.25 ml/m2; ELWI: 13.64 ± 2.82 ml/kg vs. 12.43 ± 2.50 ml/kg; Qs/Qt: 15.32 ± 6.52% vs. 12.24 ± 5.39%; all p < 0.05), Meanwhile, the oxygenation improved significantly (P/F: 184.50 ± 51.92 mmHg vs. 234.21 ± 88.84 mmHg, p < 0.05), The chest CT revealed the lung infiltrates improved significantly after PP. Both cases were discharged to a dedicated COVID-19 ward without requiring intubation. Conclusions Combining PP with HFNO could be a useful treatment strategy for avoiding intubation in severe COVID-19 patients infected with the Delta variant of SARS-CoV-2 to improve pulmonary vascular involvement, improve oxygenation and avoid intubation, but further studies are needed to validate our approach.

Abstract
Background Robotic surgery has been widely used in the radical treatment of colonic cancer. However, it is unclear what advantages the robotic approach offers over other approaches in left colectomy. This study aims to explore the advantage of robotic surgery in left colectomy by comparing open, laparoscopic, and robotic surgery. Methods A retrospective analysis was performed on the clinical data of patients with radical left colectomy for colon cancer who were admitted to the Department of General Surgery, The First Affiliated Hospital of Nanchang University, from November 2012 to November 2017. Two hundred eleven patients included were divided into the open surgery group (OS, n=49), laparoscopic surgery group (LS, n=92), and robotic surgery group (RS, n=70) according to surgical techniques. The clinicopathologic data were collected for clinical outcome assessment. Finally, the clinical value of RS in radical left colectomy was further evaluated by propensity score matching (PSM) analysis. Results Three groups were similar in demographics and clinical characteristics. Compared with OS, LS and RS groups had better intraoperative and perioperative clinical outcomes. Moreover, the RS group exhibited the minimum operative times, length of stay (LOS), and evaluated blood loss. LS and RS also exhibited less perioperative and postoperative long-term complications. Three groups showed similar postoperative pathological outcomes. The overall survival and disease-free survival were also similar among the three groups (all P > 0.05). Cox regression analysis showed surgical approach was not a prognostic factor for overall survival (P = 0.671) and disease-free survival (P = 0.776). PSM analysis of RS and LS by clinical characteristics showed RS showed shorter operation time (P < 0.001) and LOS for patients without complications (P = 0.005). However, no significant differences were found in perioperative and long-term postoperative complications, pathological outcomes, overall survival, and disease-free survival. Conclusions Among three techniques for radical left colectomy, LS and RS had significant advantages over OS in short-term clinical outcomes, and no significant differences were found in overall, disease-free survival, local recurrence, and distant metastasis incidence. Moreover, RS shows better perioperative clinical outcomes but without compromising survival compared with LS.

Abstract
Widely distributed in the alpine sandy grassland in east Qinghai-Tibet Plateau (QTP), Kengyilia melanthera is considered as an ideal pioneer grass for the restoration of degraded and desertification grassland in the region. Under the special ecological and climatic conditions in the northwest Sichuan plateau located in east QTP, it is of great significance to optimize the amount of nitrogen fertilizer for the seed production of this species. The impact of nitrogen (N) fertilizer application on seed yield and quality of K. melanthera 'Aba', the only domesticated variety in the Kengyilia genus of Poaceae, was investigated based on two-year field experiments in the northwestern Sichuan plateau. The results showed that with the increase of N fertilizer application, the number of tillers, number of fertile tillers, 1,000-seed weight and seed yield of this species increased likewise. The optimum N fertilizer rate deduced in the present study was 180 kg·hm-2, where the number of fertile tillers 1,000-seed weight and seed yield reached the peak values. Interestingly, the standard germination rate, germination energy, accelerated aging germination rate, dehydrogenase and acid phosphatase activity of seeds were not affected by the increasing the input of N fertilizer. The comprehensive evaluation of membership function showed that the optimal N fertilizer treatment was 180 kg·hm-2 both for 2016 and 2017. This study provided a certain practical suggestion for the improvement of seed production of K. melanthera in the northwest Sichuan plateau.

Abstract
Deciphering the crosstalk between RNA-binding proteins and corresponding RNAs will provide a better understanding of gastric cancer (GC) progression. The comprehensive bioinformatics study identified cytoplasmic polyadenylation element-binding protein 3 (CPEB3) might play a vital role in GC progression. Then we found CPEB3 was downregulated in GC and correlated with prognosis. In addition, CPEB3 suppressed GC cell proliferation, invasion and migration in vitro, as well as tumor growth and metastasis in vivo. Mechanistic study demonstrated CPEB3 interacted with 3'-UTR of ADAR1 mRNA through binding to CPEC nucleotide element, and then inhibited its translation by localizing it to processing bodies (P bodies), eventually leading to the suppression of ADAR1-mediated RNA editing. Microscale thermophoresis assay further revealed that the direct interaction between CPEB3 and GW182, the P-body's major component, was through the 440-698AA region of CPEB3 binding to the 403-860AA region of GW182. Finally, AAV9-CPEB3 was developed and administrated in mouse models to assess its potential value in gene therapy. We found AAV9-CPEB3 inhibited GC growth and metastasis. Besides, AAV9-CPEB3 induced hydropic degeneration in mouse liver, but did not cause kidney damage. These findings concluded that CPEB3 suppresses GC progression by inhibiting ADAR1-mediated RNA editing via localizing ADAR1 mRNA to P bodies.

Abstract
Kengyilia is a newly established genus. Most species in this genus survive in hash environment, which might be an indicator of an acquirement of stress resistance genes and the potential for molecular breeding in Triticeae species. Quantitative real-time PCR (qRT-PCR) is a widely used technique with varied sensitivity heavily dependent on the optimal level of the reference genes. K. melanthera is a typical psammophyte species which has high drought resistance. The reference genes of K. melanthera are not yet reported. This study aims to evaluate the expression stability of 14 candidate reference genes (EF1A, GAPDH, ACT1, UBI, TUBB3, TIPRL, CACS, PPP2R1B, TUBA1A, EIF4A1, CYPA3, TCTP, ABCG11L, and FBXO6L) under five treatments (drought, heat, cold, salt, and ABA) and find the most stable and suitable one even upon stressed conditions. The software NormFinder, GeNorm, BestKeeper, and RefFinder were used for data analysis. In general, the genes CACS and PPP2R1B are concluded to have the best overall performance under the various treatments. With the ABA treatment, TCTP and TIPRL show the best stability. CACS and TCTP, as well as TIPRL and CYPA3, were most stable under the treatments of cold and salt, respectively. CACS and FBXO6L were ranked the highest with the heat treatment and drought treatment, respectively. Finally, the Catalase-1 (CAT1) gene was used to verify the reliability of the above reference genes. Accordingly, CAT1’s expression pattern remained unchanged after normalization with stable reference genes. This study provides beneficial information about the stability and reliability of potential reference genes for qRT-PCR in K. melanthera.

Abstract
As a typical psammophyte of the Triticeae, Kengyilia melanthera possesses high feeding potential and great utilization values in desertification control in the Qinghai-Tibet Plateau. However, few gene function and genetic studies have been performed in K. melanthera. In this study, single-molecule real-time sequencing technology was used to obtain the full-length transcriptome sequence of K. melanthera, following the functional annotation of transcripts and prediction of coding sequences (CDSs), transcription factors (TFs), and long noncoding RNA (lncRNA) sequences. Meanwhile, a total of 42,433 SSR loci were detected, with 5'-UTRs having the most SSR loci and trinucleotide being the most abundant type. In total, 108,399 SSR markers were designed, and 300 SSR markers were randomly selected for diversity verification of K. melanthera. A total of 49 polymorphic SSR markers were used to construct the genetic relationships of 56 K. melanthera accessions, among which 21 SSR markers showed good cross-species transferability among the related species. In conclusion, the full-length transcriptome sequence of the K. melanthera will assist gene prediction and promote molecular biology and genomics research, and the polymorphic SSR markers will promote molecular-assisted breeding and related research of K. melanthera and its relatives.

Abstract
Phalaris arundinacea, with its characteristics of rapid growth and high biological yield, is regarded as an excellent forage grass in the Qinghai-Tibetan Plateau region of China. To explore the physiological and molecular response mechanism of Phalaris arundinacea under salt stress, we monitored the biomass and physiological indexes of two locally grown strains under conditions of exposure to 150 and 300 mM NaCl solution. Z0611 exhibited better salt stress tolerance than YS. Transcriptome sequencing analysis showed that YS and Z0611 had 1713 and 4290 differentially expressed genes (DEGs), respectively, including on metabolic processes, single-organism process, catalytic activity, and plant hormone signal transduction in the GO and KEGG databases. We also identified a large number of genes involved in hormone signaling, antioxidant systems, ion homeostasis, and photosynthetic systems. Our study provides physiological and molecular insight for establishing a salt resistance database and mining salt tolerance genes in Phalaris arundinacea, and also provides theoretical guidance for the restoration of saline-alkali land on the Qinghai-Tibet Plateau.

Abstract
BackgroundPatients with systemic lupus erythematosus (SLE) may have an increased risk of mortality from COVID-19 due to underlying immunosuppression, comorbidities, and abnormalities in the innate immune system. Studies have shown that autoimmune diseases and some immunosuppressive agents are risk factors for hospitalization, ventilation, and mortality from COVID-19.ObjectivesTo compare the outcomes of patients with or without SLE who were diagnosed with COVID-19 and to identify the factors associated with 30-day hospitalization, mechanical ventilation, and mortality. We hypothesized that patients with SLE had a higher risk of adverse outcomes.MethodsThis retrospective cohort study used the deidentified Optum COVID-19 electronic health record dataset to identify adult patients with COVID-19 diagnosis from 1/1/2020 – 12/31/2020. The SLE cohort was defined as patients who had two or more international classification of diseases (ICD) 9 or 10 diagnosis codes of 710.0 or M32.xx but not M32.0 within one year before COVID-19 diagnosis and were on either antimalarial or immunosuppressive therapy. The general cohort excluded patients with SLE. We matched SLE cases with controls at a ratio of 1:10 by age, sex, race and ethnicity, and month of COVID-19 diagnosis via a propensity score matching with exact matching for the latter three variables. Outcomes included 30-day mortality, hospitalization, and mechanical ventilation after COVID-19 diagnosis. We performed multivariable logistic regression models to estimate the odds of 30-day mortality, hospitalization, and mechanical ventilation after adjusting for age, sex, race and ethnicity, COVID-19 diagnosis quarter, insurance, region, severe obesity, smoking status, and comorbidities.ResultsWe included 687 SLE cases matched with 6,870 controls. After matching, the 30-day mortality for SLE and control was 3.6% and 1.8% (p <0.001), the 30-day mechanical ventilation was 6.0% and 2.5% (p <0.001), and 30-day hospitalization was 31.0% and 17.7% (p <0.001). After multivariable adjustment (Table 1) for age, sex, race, COVID-19 diagnosis quarter, insurance, region, severe obesity, and smoking status, patients with SLE had higher odds of death (Odds Ratio (OR)=2.09; 95% CI 1.31-3.32), mechanical ventilation (OR=2.43; 95% CI 1.67-3.54) and hospitalization (OR=2.06; 95% CI 1.71-2.49). After additionally adjusting for comorbidities, the OR decreased to 1.39 (95%CI 0.79-2.44), 1.81 (95%CI 1.16-2.82), and 1.32 (95%CI 1.05-1.65) for mortality, mechanical ventilation, and hospitalization respectively. Older age, male sex, Hispanic ethnicity or Black race, severe obesity, and smoking had increased risk of adverse outcomes.Table 1.Multivariable logistic regression model of 30-day mortality, 30-day mechanical ventilation, and 30-day hospitalization on matched cohort adjusting for demographic and comorbidity scoreVariablesModel 1*Odds Ratio (95% CI)Model 2**Odds Ratio (95% CI)MortalityControl11SLE2.09 (1.31 to 3.32)1.39 (0.79 to 2.44)30-day mechanical ventilationControl11SLE2.43 (95% CI 1.67 to 3.54)1.81 (1.16 to 2.82)HospitalizationControl11SLE2.06 (1.71 to 2.49)1.32 (1.05 to 1.65)SLE: systemic lupus erythematosus; CI: confidence interval.*Model 1 includes adjustments for age, sex, race, COVID-19 diagnosis date (by quarter), insurance, region, severe obesity, smoking status, and skilled nursing facility stay three months before COVID-19 diagnosis.**Model 2 includes adjustments from model 1 and comorbidities (excluding SLE).ConclusionPatients with SLE have an increased risks of mortality, mechanical ventilation, and hospitalization within 30 days of COVID-19 diagnosis.

Abstract
A detailed understanding of the distribution and degree of genetic variation within a species is important for determining their evolutionary potential, which in return facilitates the development of efficient conservation strategies aimed at preserving adaptive genetic variation. As an important perennial, cool-season grass in temperate Eurasia, increasing attention has been paid to Siberian wildrye (Elymus sibiricus) due to its excellent ecological utilization value and forage production potential in China, particularly in the Qinghai-Tibet Plateau (QTP) regions. In this study, we applied two chloroplast (cp) genes (matK and rbcL), three cp spacer regions (trnY-GUA∼trnD-GUC, atpH∼atpF, and rps4∼trnT-UGU), and six cpSSR markers to the genetic and phylogenetic analysis of 137 wild E. sibiricus accessions from 23 natural populations that represent the main distribution regions in China. The results show the highest genetic diversity (h = 0.913) and haplotype richness (10 haplotypes) for the QTP population, which indicates QTP as the probable diversity center and geographic origin of E. sibiricus in China. Population divergence was high, indicating a significant phylogeographic structure together with a significantly higher Nst value (Nst > Gst, P < 0.05) at the species level, QTP+XJ (combined populations from QTP and Xinjiang), QTP+NC (combined populations from QTP and North China), and XJ+NC (combined populations from Xinjiang and North China) group levels, respectively. An expansion was revealed in the distributional range of E. sibiricus in China from paleo times up to the recent past, while a dramatic range of contraction was predicted for the near future. The predicted main limiting factor for the further spread of E. sibiricus is an increasing global mean temperature. We recommend that the combination of Es-cpDNA1 and Es-cpDNA3+4+5 can be used as effective markers for phylogenetic analysis and phylogeographical history analysis of E. sibiricus. These findings shed new light on the historical population dynamics of cold-season herbs in the QTP region and the north of China and are of great significance for the future establishment of protection and collection strategies for wild E. sibiricus germplasm.

Abstract
Background Urogenital dysfunction is recognized as a serious complication affecting patient quality of life after rectal cancer surgery to treat rectal cancer; however, the studies focus on the urogenital function after robot-assisted rectal cancer surgery compared to laparoscopic surgery are limited. Methods Male patients undergoing robotic total mesorectal excision (R-TME) or laparoscopic total mesorectal excision (L-TME) were prospectively enrolled. The International Prostate Symptom Score (IPSS) and the five-item version of the International Index of Erectile Function (IIEF-5) scale were used to compare the urogenital function of the two groups preoperatively and 3, 6, and 12 months postoperatively. Results Eighty-nine patients who planned to undergo R-TME and L-TME were prospectively enrolled; 77 patients of these patients (86.5%) completed all questionnaires at all time points and were thus included in the final analysis. Of the included patients, 38 underwent R-TME and 39 underwent L-TME. There was no significant difference in age, BMI, American Society of Anesthesiologists (ASA) score, tumor location, neoadjuvant therapy, operation method, postoperative pathological results and adjuvant therapy between the two groups. Preoperative urogenital function was similar in both groups; however, the IPSS was significantly lower in R-TME patients than that in T-TME patients at 6 months and 12 months [(7.82 ± 2.25 vs. 9.95 ± 3.01, P = 0.006; 7.62 ± 2.5 vs. 9.12 ± 2.64, P = 0.012)]. IIEF-5 scores decreased 3 months after R-TME and L-TME surgery (14.87 ± 3.27 vs. 13.92 ± 3.62, p = 0.231) and then gradually increased; at 12 months, IIEF-5 scores were comparable to those at baseline in both groups. IIEF-5 scores were higher in R-TME patients than those in L-TME patients at 6 months (18.55 ± 3.45 vs. 16.75 ± 3.26, P = 0.021), but there was no significant difference between the two groups at 12 months (21.22 ± 3.06 vs. 19.95 ± 3.03, P = 0.071). Conclusions The robotic approach for TME was associated with more rapid restoration of male urogenital function than the laparoscopic approach.

Abstract
Background Intensive care unit-acquired weakness (ICU-AW) is common in critical illness patients and is well described. Extracorporeal membrane oxygenation (ECMO) is used as a life-saving method and patients with ECMO support often suffer more risk factors of ICU-AW. However, information on the frequency and clinical characteristics of ICU-AW in patients with ECMO support is lacking. Our study aims to clarify the frequency and characteristics of ICU-AW in ECMO patients. Methods We conducted a retrospective study, ICU-AW was diagnosed when patients were discharged with a Medical Research Council (MRC) sum score <48. Clinical information was collected from the case report forms. Univariable analysis, LASSO regression analysis, and logistic regression analysis were used to analyze the clinical data of individuals. Results In ECMO population, 40 (80%) patients diagnosed with ICU-AW. On univariable analysis, the ICU-AW group had higher Acute Physiology and Chronic Health Evaluation II (APACHE II) [13.9 (6.5-21.3) versus 21.1 (14.3-27.9), p = 0.005], longer deep sedation time [2 (0-7) versus 6.5 (3-11), p = 0.005], longer mechanical ventilation time [6.8 (2.6-9.3) versus 14.3 (6.6-19.3), p = 0.008], lower lowest albumin [26.7 (23.8-29.5) versus 22.1 (18.5-25.7), p < 0.001]. The LASSO analysis showed mechanical ventilation time, deep sedation time, deep sedation time during ECMO operation, APACHE II, and lowest albumin level were independent predictors of ICU-AW. To investigate whether ICU-AW occurs more frequently in the ECMO population, we performed a 1:1 matching with patients without ECMO and found there was no difference in the incidence of ICU-AW between the two groups. Logistic regression analysis of combined cohorts showed lowest albumin odds ratio (OR: 1.9, p = 0.024), deep sedation time (OR: 1.9, p = 0.022), mechanical ventilation time (OR: 2.0, p = 0.034), and APACHE II (OR: 2.3, p = 0.034) were independent risk factors of ICU-AW, but not ECMO. Conclusion The ICU-AW was common with a prevalence of 80% in the ECMO population. Mechanical ventilation time, deep sedation time, deep sedation time during ECMO operation, APACHE II, and lowest albumin level were risk factors of ICU-AW in ECMO population. The ECMO wasn't an independent risk factor of ICU-AW.

Abstract
Helictotrichon virescens is a perennial herbaceous plant with a life expectancy of about 10 years. It has high cold and heat resistance and can successfully survive over winter in the habitats with a temperature range of -25 to 25°C. Therefore, this study aimed to identify the key genes regulating low-temperature stress responses in H. virescens and analyze cold tolerant at molecular level. This study used RNA sequencing (RNA-Seq) and weighted gene co-expression network analysis (WGCNA) to identify the hub genes associated with cold tolerance in H. virescens. RT-PCR was conducted, homologous genes were identified, and related bioinformatics were analyzed to verify the identified hub genes. Moreover, WGCNA analysis showed that only the brown module had the highest correlation with the active-oxygen scavenging enzymes [peroxide (POD), superoxide dismutase (SOD), and catalase (CAT)]. The expression levels of three hub genes in the brown module (Cluster-37118.47362, cluster-37118.47713, and cluster-37118.66740) were significantly higher under low-temperature stress than those under control conditions. Furthermore, gene ontology (GO) and KEGG annotations showed that the three hub genes were mainly enriched in the metabolism pathways of sphingolipids, selenocompounds, glyoxylate, and dicarboxylate, carotenoids biosynthesis, and other biological pathways. The results of this study also showed that the subcellular localization prediction results showed that the cold tolerance hub genes were all localized to the plasma membrane. By constructing a protein interaction network, it was found that the hub gene Cluster-37118.66740 interacted with Sb09g003460.1 and Sb04g020180.1 proteins in Sorghum bicolor. By constructing phylogenetic trees of the four species of H. virescens, Sorghum bicolo, Oryza sativa Japonica, and Arabidopsis thaliana, the results showed that, the hub gene Cluster 37118.66740 (of H. virescens) and Os03g0340500 (of Oryza sativa Japonica) belonged to the same ancestral branch and were in the same subfamily. Thus, this study provides methodology and guidance to identify the cold tolerance genes for other herbage and their cold tolerant molecular mechanisms at molecular level.

Abstract
OBJECTIVES Our objective was to evaluate if SARC-F, SARC-CalF, SARC-F-EBM, calf circumference (CC), mid-upper-arm circumference (MUAC) and Ishii test can be used to accurately screen for sarcopenia in schizophrenic patients. METHOD We enrolled schizophrenic patients aged 50 or older, who were regularly taking antipsychotic medications, at two mental health centres. Bioimpedance-based muscle-mass was analysed with an InBody 770 instrument, while muscle strength was measured with a digital grip-strength dynamometer. The physical performance of the patients was gauged from their gait speed over 6 m. Standard AWGS2019 diagnostic criteria were used, and the accuracies of the six screening methods were indicated by the sensitivity, negative predictive value (NPV), and area under receiver operating characteristic curve (AUC). RESULTS A total of 339 stable schizophrenic patients were enrolled. The overall prevalence of sarcopenia was 53.1%, and the prevalence was 55.6% and 47.66%, respectively, for males and females. The prevalence of sarcopenia obesity in the total population was 16.22%, and that of males and females was 18.97% and 10.28%, respectively. The SARC-F, SARC-CalF, SARC-F-EBM, CC, MUAC and Ishii test sensitivity/NPV in screening for sarcopenia were 41.86%/0.52, 79.07%/0.7, 28.68%/0.51, 78.3%/0.71, 76.74%/0.7, 89.92%/0.84, respectively, in males and 45.1%/0.59, 94.12%/0.91, 54.9%/0.7, 92.16%/60.91, 74.51%/0.77, 96.08%/0.94, respectively, in females. In males, the AUCs of the SARC-F, SARC-CalF, SARC-F-EBM, CC, MUAC and Ishii test were 0.601 (95%CI, 0.528-0.673), 0.754 (95%CI,0.69-0.817), 0.657 (95%CI,0.588-0.727), 0.8 (95%CI, 0.744-0.856), 0.781 (95%CI, 0.721-0.84) and 0.88 (95%CI, 0.837-0.922), respectively, and in females, they were 0.587(95%CI,0.479-0.696), 0.794 (95%CI,0.709-0.878), 0.799 (95%CI,0.71-0.888), 0.893 (95%CI, 0.833-0.953), 0.843 (95%CI, 0.772-0.915) and 0.855 (95%CI, 0.784-0.926), respectively. CONCLUSION The prevalence of sarcopenia in schizophrenic patients is high. Clinical doctors should screen for sarcopenia in schizophrenic patients and provide timely interventions to reduce the occurrence of adverse events. The above six tools can be used as screening tools, and the Ishii test is the most suitable for screening.

Abstract
OBJECTIVES This study investigates the associations between the severity of sarcopenia and pneumonia in patients with stable schizophrenia. MATERIALS AND METHODS This is a prospective study that includes patients from the rehabilitation wards of two mental health centres in western China, who were diagnosed with stable schizophrenia. Baseline data were collected from these patients between September 1 and September 30, 2020, while patients' data associated with pneumonia, diagnosed and treated by clinicians, were collected between October 2020 and October 2021. The severity of sarcopenia was diagnosed according to the diagnostic criteria defined by the Asian Working Group for Sarcopenia (AWGS) 2019. The association between the severity of sarcopenia and pneumonia in patients with schizophrenia was analyzed with the use of logistic regression analysis. RESULTS Three hundred and thirty-five patients with stable schizophrenia were enrolled in the prospective study, among whom 242 (72.24%) were≥60 years old, and 229 (68.36%) were males. Among the patients with stable schizophrenia, 130 (38.8%) were diagnosed with non-severe sarcopenia, whereas 47 (14.0%) had severe sarcopenia. Eighty-two (24.5%) of patients with schizophrenia fought pneumonia. Our study showed that the severe sarcopenia group had the highest incidence of pneumonia, followed by the non-severe sarcopenia group (severe sarcopenia vs. non-severe sarcopenia vs. normal, 38.3% vs. 28.46% vs. 17.09%, p=0.005). Compared with the normal group, the non-severe sarcopenia group (OR=1.93, 95%CI: 1.1-3.389) and the severe sarcopenia group (OR=3.011, 95%CI: 1.467-6.183) had a higher risk of pneumonia. We further adjusted the potential confounders such as sex, smoking history, chronic obstructive pulmonary disease (COPD), Patient Health Questionnaire (PHQ-9) score, and benzhexol and confirmed that only the severe sarcopenia group had an increased risk of pneumonia (OR=2.366, 95%CI: 1.078-5.191). CONCLUSIONS We have demonstrated that severe sarcopenia was associated with pneumonia in patients diagnosed with stable schizophrenia.

Abstract
High temperature (HT) is an important factor for limiting global plant distribution and agricultural production. As the global temperature continues to rise, it is essential to clarify the physiological and molecular mechanisms of alfalfa responding the high temperature, which will contribute to the improvement of heat resistance in leguminous crops. In this study, the physiological and proteomic responses of two alfalfa (Medicago sativa L.) varieties contrasting in heat tolerance, MS30 (heat-tolerant) and MS37 (heat-sensitive), were comparatively analyzed under the treatments of continuously rising temperatures for 42 days. The results showed that under the HT stress, the chlorophyll content and the chlorophyll fluorescence parameter (Fv/Fm) of alfalfa were significant reduced and some key photosynthesis-related proteins showed a down-regulated trend. Moreover, the content of Malondialdehyde (MDA) and the electrolyte leakage (EL) of alfalfa showed an upward trend, which indicates both alfalfa varieties were damaged under HT stress. However, because the antioxidation-reduction and osmotic adjustment ability of MS30 were significantly stronger than MS37, the damage degree of the photosynthetic system and membrane system of MS30 is significantly lower than that of MS37. On this basis, the global proteomics analysis was undertaken by tandem mass tags (TMT) technique, a total of 6,704 proteins were identified and quantified. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated that a series of key pathways including photosynthesis, metabolism, adjustment and repair were affected by HT stress. Through analyzing Venn diagrams of two alfalfa varieties, 160 and 213 differentially expressed proteins (DEPs) that had dynamic changes under HT stress were identified from MS30 and MS37, respectively. Among these DEPs, we screened out some key DEPs, such as ATP-dependent zinc metalloprotease FTSH protein, vitamin K epoxide reductase family protein, ClpB3, etc., which plays important functions in response to HT stress. In conclusion, the stronger heat-tolerance of MS30 was attributed to its higher adjustment and repair ability, which could cause the metabolic process of MS30 is more conducive to maintaining its survival and growth than MS37, especially at the later period of HT stress. This study provides a useful catalog of the Medicago sativa L. proteomes with the insight into its future genetic improvement of heat-resistance.

Abstract
Objective: To investigate the effects of long-term moderate-small intensity aerobic exercise on the differential expression of proteome in left ventricular muscle of rats, and to screen the target proteins sensitive to moderate-small intensity aerobic exercise stimulation. This study will enrich the basic theory of exercise and fitness and provide new ideas and experimental basis for the rehabilitation treatment of chronic cardiovascular disease. Methods: Twenty male SD rats were randomly divided into exercise group and control group (n=10). The treadmill training model of long-term moderate-small intensity aerobic exercise was established, and the whole protein samples of left ventricular muscle were extracted and separated by two-dimensional gel electrophoresis (2-DE). The two-dimensional gel electrophoresis map was analyzed by Bio PD quest image analysis software. The protein spots with differential expression more than 5 times or down-regulated over 80% after exercise were identified by tandem time-of-flight mass spectrometry (ULGRAFL-FLEX-TOF/TOF). Results: Compared with the group C, the heart weight index of the group E was increased by 32.0%, and the difference was significant (P<0.05). Compared with the group C, there were 71 protein spots expression were up-regulated≥2 times or down-regulated≥50% in the group E. 4 protein spots expression were up-regulated≥5 times or down-regulated≥80% were identified by mass spectrometry, 3 proteins and 1 unknown protein were identified. Conclusion: After long-term moderate-small intensity aerobic exercise, the rats heart had a good adaptive change, and the proteome of left ventricular muscle changed significantly. Long-term moderate-small intensity aerobic exercise can effective enhance the ability of myocardial antioxidation.

Abstract
Duodenal cavernous haemangiomas are rare, benign disorders, and massive gastrointestinal (GI) bleeding is a rare clinical condition. The present case report describes a 50-year-old male patient who presented with severe, ongoing haematochezia. A peripheral blood smear at the time of admission showed significant anaemia, and haemoglobin level was 52 g/l (normal range, 120–175 g/l). Albumin level was also low at 28 g/l (normal range, 40–55 g/l). Standard computed tomography (CT) showed mural thickening and relative lumen stenosis in the ascending (fourth) portion of the duodenum. Contrast-enhanced CT using hypotonic solution revealed the lesions to be hypervascular haemangiomas. Laparotomy and segmental duodenum resection were performed, and the first jejunal limb was anastomosed using a side-to-end technique. Histopathological examination confirmed the diagnosis of cavernous haemangioma. The patient showed marked improvement during follow-up. The present case findings emphasize that duodenal haemangioma is possible without a history of chronic anaemia, and should remain a consideration in differential diagnosis for patients presenting with massive GI bleeding. CT is useful for preoperative diagnosis of massive bleeding, and surgery with segmental resection is usually curative.

Abstract
Background Robotic surgery has been taken as a new modality to surpass the technical limitations of conventional surgery. Here we aim to compare the oncologic outcomes of patients with rectal cancer receiving robotic vs. laparoscopic surgery. Methods Data from patients diagnosed with rectal cancer between March 2011 and December 2018 were obtained for outcome assessment at the First Affiliated Hospital of Nanchang University. All patients were separated into two groups: a robot group (patients receiving robotic surgery, n = 314) and a laparoscopy group (patients receiving laparoscopic surgery, n = 220). The primary endpoint was survival outcomes. The secondary endpoints were the general conditions of the operation, postoperative complications and pathological characteristics. Results The 5-year overall survival (OS) and disease-free survival (DFS) at years 1, 3 and 5 were 96.6%, 88.7%, and 87.7% vs. 96.7%, 88.1%, and 78.4%, and 98.6%, 80.2-, and 73.5% vs. 96.2-, 87.2-, and 81.1% in the robot and laparoscopy groups, respectively (P > 0.05). In the multivariable-adjusted analysis, robotic surgery was not an independent prognostic factor for OS and DFS (P = 0.925 and 0.451, respectively). With respect to the general conditions of the operation, patients in the robot group had significantly shorter operation times (163.5 ± 40.9 vs. 190.5 ± 51.9 min), shorter times to 1st gas passing [2(1) vs. 3(1)d] and shorter hospital stay days [7(2) vs. 8(3)d] compared to those in the laparoscopy group (P < 0.01, respectively). After the operation, the incidence of short- and long-term complications in the robot group was significantly lower than that in the laparoscopy group (15.9% vs. 32.3%; P < 0.001), especially for urinary retention (1.9% vs. 7.3%; 0.6% vs. 4.1%, P < 0.05, respectively). With regard to pathological characteristics, TNM stages II and III were more frequently observed in the robot group than in the laparoscopy group (94.3% vs. 83.2%, P < 0.001). No significant difference were observed in lymph nodes retrieved, lymphovascular invasion and circumferential resection margin involvement between the two groups (P > 0.05, respectively). Conclusions This monocentre retrospective comparative cohort study revealed short-term advantages of robot-assisted rectal cancer resection but similar survival compared to conventional laparoscopy.

Abstract
OBJECTIVES We examined the mediation effects of psychosocial adjustment on the impact of playmate positive support throughout childhood and early adolescence (from age 54 months to 11 years) on later body mass index (BMI) and overweight risk in middle adolescence (age 15 years). STUDY DESIGN This was a prospective cohort study. METHODS Among 844 children and their families, positive support between child-playmate dyads was repeatedly assessed from child's age 54 months to Grade 5. Long-term positive support between child-playmate dyads throughout childhood and early adolescence was prospectively linked to child's BMI and overweight/obesity status at age 15 years. The average scores of repeated assessments of internalizing and externalizing behavior problems from Grades 3 to 6 were used as mediators. RESULTS Significant mediations of internalizing and externalizing behavior problems were observed on pathways from positive support between child-playmate dyads to later BMI and overweight/obesity status at age 15 years. The observed mediations were mainly sustained with pronounced magnitudes in girls, but not in boys. CONCLUSIONS Our findings demonstrated a significant mediating role of psychosocial adjustment. Future research efforts are highly encouraged to replicate our findings and further explore this underlying mediation mechanism.

Abstract
miR-144-3p is aberrantly expressed in several types of human cancer and functions as a tumor suppressor by inhibiting metastasis. However, the clinical significance and biological function of miR-144-3p in colorectal adenocarcinoma (CRA) have yet to be elucidated. Here we reported that miR-144-3p expression level was significantly down-regulated in CRA tissues compared with matched noncancerous colorectal mucosae tissues. Low miR-144-3p expression was correlated with adverse clinicopathologic characteristics and poor prognosis of CRA patients. Cox regression analysis showed that low miR-144-3p expression was an independent risk factor for DFS and OS in CRA. In vitro and in vivo assays showed that miR-144-3p significantly inhibited proliferation, migration and invasion of CRA cells. In particular, miR-144-3p could suppress EMT process of CRA cells by regulating the cytoskeleton and EMT markers. Bioinformatics analysis indicated that EMT associated transcription factors ZEB1 and ZEB2 were potential targets of miR-144-3p, and miR-144-3p inhibited ZEB1 and ZEB2 expression and was negatively correlated with their expression in CRA. Finally, we confirmed that ZEB1 and ZEB2 down-regulation collaboratively mediated the inhibitory effect of miR-144-3p on proliferation, invasion and EMT of CRA cells. In conclusion, our study provided evidence that miR-144-3p could inhibit CRA cell proliferation, invasion and EMT by targeting ZEB1/2.

Abstract
The Coatomer protein complex subunit beta 2 (COPB2) is involved in the formation of the COPI coatomer protein complex and is responsible for the transport of vesicles between the Golgi apparatus and the endoplasmic reticulum. It plays an important role in maintaining the integrity of these cellular organelles, as well as in maintaining cell homeostasis. More importantly, COPB2 plays key roles in embryonic development and tumor progression. COPB2 is regarded as a vital oncogene in several cancer types and has been implicated in tumor cell proliferation, survival, invasion, and metastasis. Here, we summarize the current knowledge on the roles of COPB2 in cancer development and progression in the context of the hallmarks of cancer.

Abstract
As a high-yielding forage grass, Phalaris arundinacea widely distributed in the Qinghai-Tibet Plateau region of China. To explore physiological and molecular response mechanism of Phalaris arundinacea under waterlogging, we analyzed the biomass and physiological indexes of three locally grown strains under the submerged condition of 10 cm. The material Z0611 showed the strongest waterlogging resistance while the YS showed the weakest performance. Transcriptome sequencing analysis demonstrated that the YS and Z0611 had 17010 and 7566 differently expression genes (DEGs), respectively, which were mainly concentrated in the metabolic process, cell, ribosome, phenylpropanoid biosynthesis pathway in GO and KEGG databases. We also identified a large number of genes involved in carbohydrate metabolism, hormone signaling regulation, transcription factors, antioxidant system, and ethylene signaling. Our research may provide a scientific basis for the restoration of wetland environment on the Qinghai-Tibet Plateau, and lay a foundation for further exploration of the waterlogging resistance genes of Phalaris arundinacea and breeding of new strains resistant with waterlogging stress.

Abstract
Tumor-associated macrophages (TAMs) in the tumor microenvironment contribute to poor prognosis in gastric cancer (GC). However, the underlying mechanism by which TAMs promote GC progression and metastasis remains elusive. Expression of POU1F1 was detected in 60 matched GC-normal tissue pairs using qRT-PCR and immunohistochemistry (IHC) analysis. The correlation between POU1F1 and the clinical-pathological factors of GC patients were further assessed. Cell proliferation was monitored by CCK-8, colony formation, and 5-Ethynyl-2'-deoxyuridine (EdU) incorporation assays. Cell migration and invasion were assessed by transwell assays. The impact on angiogenesis was evaluated by tube formation assay. Xenograft model was generated to investigate the role of POU1F1 on tumor growth and lung metastasis in vivo. GST pull-down and Co-immunoprecipitation (Co-IP) were used to study the interaction between HMGA1B/2 and POU1F1. Chromatin immunoprecipitation (ChIP) and dual luciferase reporter assays were performed to investigate the transcriptional regulation of POU1F1. Flow cytometry was performed to detect the surface expression of macrophage markers. Upregulated POU1F1 observed both in GC tissues and cell lines was positively correlated with poor prognosis. Knockdown of POU1F1 inhibited cell proliferation, migration, invasion, and angiogenesis in vitro, and suppressed tumor growth in vivo. HMGA1B/2 transcriptionally activated-POU1F1. POU1F1 promoted GC progression via regulating macrophage proliferation, migration, polarization, and angiogenesis in a CXCL12/CXCR4-dependent manner. POU1F1 also promoted GC metastasis in lung by modulating macrophage polarization through CXCL12/CXCR4 axis in vivo. HMGA1B/2-upregulated POU1F1 promoted GC metastasis via regulating macrophage polarization in a CXCL12/CXCR4-dependent manner.

Abstract
Introduction: Liver metastasis is the main cause of death in colorectal cancer (CRC). Premetastatic niche (PMN), a favorable microenvironment for cancer cells colonization at the distant organ, plays a pivotal role in CRC liver metastasis (CRCLM). Our understanding of the mechanisms mediating the formation of liver PMN in CRC has been significantly advanced in recent years, there are still many challenges and questions that remain.Areas covered: This review covers cellular and molecular components, and the interaction of theprimary cancer with the resident microenvironment of the distant organ that leads to PMN formation in CRCLM based on the latest literature.Expert Opinion: Various cellular and molecular events are involved in the liver PMN formation in CRC such as bone marrow-derived cells (BMDCs), hepatic stellate cells, Kupffer cells, extracellular matrix, and CRC-derived factors. The formation of the liver PMN depends on a complex interaction of CRC with the liver microenvironment including BMDCs recruitment, vascularization, immunosuppression, inflammatory response, and extracellular matrix remodeling. This review firstly discusses on the cellular and molecular components contributing to the formation of the liver PMN in CRC, so as to provide new ideas for designing effective therapeutic strategies and prognostic markers for CRCLM.

Abstract
OBJECTIVE Robotic and laparoscopic surgery for rectal cancer has been applied in the clinic for decades; nevertheless, which surgical approach has a lower rate of postoperative complications is still inconclusive. Therefore, the aim of this meta-analysis was to compare the postoperative complications within 30 days between robotic and laparoscopic rectal cancer surgery based on randomized controlled trials. METHODS Randomized controlled trials (until May 2020) that compared robotic and laparoscopic rectal cancer surgery were searched through PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, and China Biology Medicine disc (CBMdisc). Data regarding sample size, clinical and demographic characteristics, and postoperative complications within 30 days, including overall postoperative complications, severe postoperative complications (Clavien-Dindo score ≥ III), anastomotic leakage, surgical site infection, bleeding, ileus, urinary complications, respiratory complications, conversion to open surgery, unscheduled reoperation, perioperative mortality, and pathological outcomes, were extracted. The results were analyzed using RevMan v5.3. RESULTS Seven randomized controlled trials that included 507 robotic and 516 laparoscopic rectal cancer surgery cases were included. Meta-analysis showed that the overall postoperative complications within 30 days [Z = 1.1, OR = 1.18, 95% CI (0.88-1.57), P = 0.27], severe postoperative complications [Z = 0.22, OR = 1.12, 95% CI (0.41-3.07), P = 0.83], anastomotic leakage [Z = 0.96, OR = 1.27, 95% CI (0.78-2.08), P = 0.34], surgical site infection [Z = 0.18, OR = 1.05, 95% CI (0.61-1.79), P = 0.86], bleeding [Z = 0.19, OR = 0.89, 95% CI (0.27-2.97), P = 0.85], ileus [Z = 1.47, OR = 0.66, 95% CI (0.38-1.15), P = 0.14], urinary complications [Z = 0.66, OR = 1.22, 95% CI (0.67-2.22), P = 0.51], respiratory complications [Z = 0.84, OR = 0.64, 95% CI (0.22-1.82), P = 0.40], conversion to open surgery [Z = 1.73, OR = 0.61, 95% CI (0.35-1.07), P = 0.08], unscheduled reoperation [Z = 0.14, OR = 0.91, 95% CI (0.26-3.20), P = 0.89], perioperative mortality [Z = 0.28, OR = 0.79, 95% CI (0.15-4.12), P = 0.78], and pathological outcomes were similar between robotic and laparoscopic rectal surgery. CONCLUSION Robotic surgery for rectal cancer was comparable to laparoscopic surgery with respect to postoperative complications within 30 days.

Abstract
BACKGROUND Siberian wildrye (Elymus sibiricus L.) attracts considerable interest for grassland establishment and pasture recovery in the Qinghai-Tibet Plateau (QTP) due to its excellence in strong stress tolerance, high nutritional value and ease to cultivate. However, the lack of genomic information of E. sibiricus hampers its genetics study and breeding process. RESULTS In this study, we performed a genome survey and developed a set of SSR markers for E. sibiricus based on Next-generation sequencing (NGS). We generated 469.17 Gb clean sequence which is 58.64× of the 6.86 Gb estimated genome size. We assembled a draft genome of 4.34 Gb which has 73.23% repetitive elements, a heterozygosity ratio of 0.01% and GC content of 45.68%. Based on the gnomic sequences we identified 67,833 SSR loci and from which four hundred were randomly selected to develop markers. Finally, 30 markers exhibited polymorphism between accessions and ten were identified as single-locus SSR. These newly developed markers along with previously reported 30 ones were applied to analyze genetic polymorphism among 27 wild E. sibiricus accessions. We found that single-locus SSRs are superior to multi-loci SSRs in effectiveness. CONCLUSIONS This study provided insights into further whole genome sequencing of E. sibiricus in strategy selection. The novel developed SSR markers will facilitate genetics study and breeding for Elymus species.
