Abstract
BACKGROUND Stroke is a debilitating condition with high morbidity, disability, and mortality that significantly affects the quality of life of patients. In China, the WenYang FuYuan recipe is widely used to treat ischemic stroke. However, the underlying mechanism remains unknown, so exploring the potential mechanism of action of this formula is of great practical significance for stroke treatment. OBJECTIVE This study employed network pharmacology, molecular docking, and in vivo experiments to clarify the active ingredients, potential targets, and molecular mechanisms of the WenYang FuYuan recipe in cerebral ischemia-reperfusion injury, with a view to providing a solid scientific foundation for the subsequent study of this recipe. MATERIALS AND METHODS Active ingredients of the WenYang FuYuan recipe were screened using the traditional Chinese medicine systems pharmacology database and analysis platform. Network pharmacology approaches were used to explore the potential targets and mechanisms of action of the WenYang FuYuan recipe for the treatment of cerebral ischemia-reperfusion injury. The Middle Cerebral Artery Occlusion/Reperfusion 2 h Sprague Dawley rat model was prepared, and TTC staining and modified neurological severity score were applied to examine the neurological deficits in rats. HE staining and Nissl staining were applied to examine the pathological changes in rats. Immunofluorescence labeling and Elisa assay were applied to examine the expression levels of certain proteins and associated factors, while qRT-PCR and Western blotting were applied to examine the expression levels of linked proteins and mRNAs in disease-related signaling pathways. RESULTS We identified 62 key active ingredients in the WenYang FuYuan recipe, with 222 highly significant I/R targets, forming 138 pairs of medication components and component-targets, with the top five being Quercetin, Kaempferol, Luteolin, β-sitosterol, and Stigmasterol. The key targets included TP53, RELA, TNF, STAT1, and MAPK14 (p38MAPK). Targets related to cerebral ischemia-reperfusion injury were enriched in chemical responses, enzyme binding, endomembrane system, while enriched pathways included lipid and atherosclerosis, fluid shear stress and atherosclerosis, AGE-RAGE signaling in diabetic complications. In addition, the main five active ingredients and targets in the WenYang FuYuan recipe showed high binding affinity (e.g. Stigmasterol and MAPK14, total energy <-10.5 Kcal/mol). In animal experiments, the WenYang FuYuan recipe reduced brain tissue damage, increased the number of surviving neurons, and down-regulated S100β and RAGE protein expression. Moreover, the relative expression levels of key targets such as TP53, RELA and p38MAPK mRNA were significantly down-regulated in the WenYang FuYuan recipe group, and serum IL-6 and TNF-a factor levels were reduced. After WenYang FuYuan recipe treatment, the AGE-RAGE signaling pathway and downstream NF-kB/p38MAPK signaling pathway-related proteins were significantly modulated. CONCLUSION This study utilized network pharmacology, molecular docking, and animal experiments to identify the potential mechanism of the WenYang FuYuan recipe, which may be associated with the regulation of the AGE-RAGE signaling pathway and the inhibition of target proteins and mRNAs in the downstream NF-kB/p38MAPK pathway.

Abstract
Objective: To analyze the differences between trans-radial access (TRA) and trans-femoral access (TFA) in hepatic arterial perfusion chemotherapy (HAIC) in terms of patient experience, postoperative complications, and patient preferences; explore whether TRA in HAIC is associated with better patient experience and compliance; and determine whether it is safer than TFA. Methods: The study was a retrospective cohort study of patients with advanced hepatocellular carcinoma and liver metastases from colorectal cancer treated with HAIC. We enrolled a total of 91 patients with advanced liver malignancies treated with HAIC from November 2022 to May 2023 in the Department of Interventional Therapy and Hepatobiliary Medicine at Tianjin Medical University Cancer Hospital. The patients were divided into three groups: group TRA (n=20, receiving TRA HAIC only), group TFA (n=33, receiving TFA HAIC only), and crossover group [n=19, receiving TFA HAIC (Cross-TFA group) first, followed by TRA HAIC (Cross-TRA group)]. Meanwhile, to facilitate the expression of partial results, all patients receiving TRA HAIC were defined as the TRA-HAIC group (n=39, TRA+Cross-TRA group), and all patients receiving TFA HAIC were defined as the TFA-HAIC group (n=52, TFA+Cross-TFA group). The primary research index was the Quality of Life (QOL) visualization scale score. The secondary research index included approach-related and catheter-related adverse events, duration of surgery, and mean length of patient stay. We used various statistical methods such as Mann-Whitney U test, t-test, Chi-square test, Fisher's exact test, univariate logistic regression analysis, and multi-factor analysis. Results: TRA patients had significantly lower QOL scores than TFA patients (all P<0.001). The QOL scores of the Cross-TRA group were significantly lower than those of the Cross-TFA group (pain at the puncture site Z=-3.24, P=0.001, others P<0.001). The QOL scores of the Cross-TRA group were compared with those of the TRA group, which showed that the scores of the Cross-TRA group in overall discomfort (Z=-3.07,P=0.002), postoperative toilet difficulty (Z=-2.12, P=0.034), and walking difficulty (Z=-2.58, P=0.010) were significantly lower than those of the TRA group. Satisfaction scores were significantly higher in the Cross-TRA group than in the Cross-TFA group (Z=-3.78, P<0.001), and patients were more likely to receive TRA HAIC as the next procedure (χ2=30.42, P<0.001). In terms of mean length of stay, patients receiving TRA HAIC had a significantly lower mean length of stay than those receiving TFA HAIC (50.1±3.2 h vs. 58.4±6.4 h, t=7.98, P<0.001). The incidence of radial artery occlusion (RAO) as an approach-related adverse event was 15.4% (6/39) in the TRA-HAIC group, which was significantly higher than that in the TFA-HAIC group (15.4% vs. 0, χ2=8.56, P=0.005). Notably, multifactorial analysis of RAO-related factors showed that intraoperative enoxaparin use and patency of radial artery flow during pressure were significantly associated with a reduced risk of postoperative RAO (P=0.037 for enoxaparin use and P=0.049 for pressure). Conclusions: With respect to procedure approach, TRA was significantly better than TFA in terms of patient satisfaction and mean length of stay. Through further process optimization and prevention of adverse reactions, the incidence of adverse reactions can be maintained at a relatively low level, so that patients can benefit from TRA in future operations in terms of cost-effectiveness and medical efficiency.

Abstract
In this study, a porous structure for a porous liquid storage medium is generated, and the homogenization theory based on displacement boundary conditions is used to predict the effective mechanical properties. The relationship between the porous material's macroscopic mechanical properties and microstructure is next analyzed. In order to establish the relationship between the microstructure of porous materials and their macroscopic mechanical properties, assuming that the pores grow along the z direction, a method is proposed to generate 3D open-cell porous materials based on six design parameters (i.e., the number of pores, porosity, irregularity of pore distribution, the randomness of pore growth in the x and y directions, and randomness of pore size). Since the porosity of oil-bearing materials ranges from 20 to 30%, the porosity of the RVE (Representative Volume Element) was kept under control at about 25%, and the effect of the six design factors on the mechanical properties of the RVE was investigated. Utilizing SLA 3D printing technology, specimens were produced, and compression tests were used to show how useful the results of the numerical analysis were. The results demonstrated that after the number of RVE pores reaches 9, the numerical results have good repeatability. The irregularity of the initial pore distribution has little effect on the effective mechanical properties of the RVE. At the same time, the increase in the randomness of pore growth and the randomness of pore size increases the degree of weakening of the mechanical properties in the z-direction, while reducing the degree of weakening in the x and y directions, but the latter has a smaller impact. Furthermore, there is a superimposition effect of design parameters on the RVE.

Abstract
Dentition defects damage the integrity of the dental arch, affecting smile esthetics and oral function. Compared to restorative treatment, pre-restoration orthodontic treatment overcomes the limitations of a single method, effectively avoiding excessive wear of natural teeth, reducing the number of units for restorative production to a certain extent, and potentially improving facial shape and occlusal relationship, which maximizes the therapeutic effect. This article explores the key points of pre-restoration orthodontic treatment for different types of dentition defects in terms of malocclusion manifestations, treatment objectives, treatment methods, and maintenance recommendations from the perspective of combined orthodontic restoration treatment.

Abstract
Water and fertilizer managements are the most common practices to maximize crop yields, and their long-term impact on soil microbial communities has been extensively studied. However, the initial response of microbes to fertilization and soil moisture changes remains unclear. In this study, the immediate effects of nitrogen (N)-fertilizer application and moisture levels on microbial community of paddy soils were investigated through controlled incubation experiments. Amplicon sequencing results revealed that moisture had a stronger influence on the abundance and community composition of total soil bacteria, as well as ammonia oxidizing-archaea (AOA) and -bacteria (AOB). Conversely, fertilizer application noticeably reduced the connectivity and complexity of the total bacteria network, and increasing moisture slightly exacerbated these effects. NH4+-N content emerged as a significant driving force for changes in the structure of the total bacteria and AOB communities, while NO3--N content played more important role in driving shifts in AOA composition. These findings indicate that the initial responses of microbial communities, including abundance and composition, and network differ under water and fertilizer managements. By providing a snapshot of microbial community structure following short-term N-fertilizer and water treatments, this study contributes to a better understanding of how soil microbes respond to long-term agriculture managements.

Abstract
OBJECTIVE To explore the clinical efficacy of Zhuang Medicine Lotus Acupuncture Cupping Stasis Therapy on patients with postherpetic neuralgia (PHN) and its action mechanism. METHODS 36 patients are randomly divided into Lotus Acupuncture Cupping Stasis Therapy group, pure cupping group and gabapentin group, with a total of five observation points for the first, fifth, tenth, fifteenth, and twentieth sessions of therapy (one session every three days). At each observation point, the venous blood of the patients is taken, and the contents of and changes in WNT3a, Frizzled8, β-catenin, IL-18, TNF-α, NR2B, NK-1 and SP are tested by ELISA, RT-PCR and WesternBlot, respectively. The VAS scores and safety of the patients in the three groups are compared. RESULTS With increased time spent in therapy, the VAS scores of patients in each group decreased gradually and there was a significant reduction in pain in patients in the Lotus Acupuncture Cupping Stasis Therapy group compared to the gabapentin and pure cupping groups (P<0.05). The levels of IL-18, TNF-α, NK-1, SP, WNT3a, Frizzled 8 and β-catenin in the serum of all patients experienced a constant decline over time (P<0.05); the levels of the aforesaid factors in the serum of patients in the Lotus Acupuncture Cupping Stasis Therapy group dropped remarkably after the tenth session of therapy compared to those in gabapentin and pure cupping groups (P<0.05). CONCLUSIONS Zhuang Medicine Lotus Acupuncture Cupping Stasis Therapy can significantly reduce the pain of PHN patients, with a good therapeutic effect, and it is worthy of clinical use.

Abstract
Cu nanowires and a nanoporous Ag matrix were fabricated through directional solidification and selective dissolution of Ag-Cu eutectic alloys. Ag-39.9at.%Cu eutectic alloys were directionally solidified at growth rates of 14, 25, and 34 μm/s at a temperature gradient of 10 K/cm. The Cu phase in the Ag matrix gradually changed from lamellar to fibrous with an increase in the growth rate. The Ag matrix phase was selectively dissolved, and Cu nanowires of 300-600 nm in diameter and tens of microns in length were prepared in 0.1 M borate buffer with a pH of 9.18 at a constant potential of 0.7 V (vs. SCE). The nanoporous Ag matrix was fabricated through selective dissolution of Cu fiber phase in 0.1 M acetate buffer with a pH of 6.0 at a constant potential of 0.5 V (vs. SCE). The diameter of Ag pores decreased with increasing growth rate. The diameter and depth of Ag pores increased when corrosion time was extended. The depth of the pores was 30 μm after 12 h.

Abstract
Abstract
Aims
Sex refers to genetic and biological characteristics, whereas gender reflects psychosocial norms, roles and behaviors. Sex differences in new-onset heart failure are well described, but gender differences in new-onset heart failure with preserved (HFpEF) and reduced left ventricular ejection fraction (HFrEF) are unknown.
Methods
A total of 6830 participants (50.3% women, mean age of 54 years) from the Prevention of Renal and Vascular End-Stage Disease (PREVEND) observational Dutch cohort were enrolled in the study. Gender-related characteristics were assessed using self-administered questionnaires. LASSO regression analysis selected the psychosocial variables related to sex, whose coefficient estimates were used to calculate the gender-related scores for each subject [1–2]. The participants were grouped by sex and further analyzed according to tertiles of the gender-related score. Competing-risk regression analysis was used to assess whether sex and gender were associated with new-onset HFrEF (LVEF ≤40%) and HFpEF (LVEF ≥50%).
Results
Women with predominantly masculine gender had lower BMI, were more often Caucasian and had higher total cholesterol and high-density lipoprotein (HDL) levels than women with a predominantly feminine gender. Men with predominantly feminine gender were less often Caucasian with lower total cholesterol and HDL cholesterol levels than men with a predominantly masculine gender. During a median follow-up of 8.3 years, 227 (3.3%) subjects were diagnosed with heart failure (57.3% HFrEF and 43.7% HFpEF). In the total population including both men and women, feminine gender was significantly and independently associated with a higher risk of new-onset HFpEF compared with masculine gender (HR per 10 point: 1.17, 95% CI: 1.06–1.30; p=0.003). However, sex was not associated with new-onset HFpEF (HR: 1.09, 95% CI: 0.73–1.62; p=0.670). Separately in men, feminine gender was associated with a higher risk of new-onset HFpEF (HR: 1.37, 95% CI: 1.06–1.78; p=0.017), but not in women (HR: 1.13, 95% CI: 0.90–1.41; p=0.310).
Conclusions
Gender and sex are different constructs and feminine gender was associated with an increased risk of new-onset HFpEF, whereas sex was not associated with new-onset HFpEF.

Abstract
Objectives: To evaluate the effects of steatotic donor livers on the safety of donors and the prognosis of donors and recipients in pediatric living donor liver transplantation. Methods: A total of 814 pediatric living donor liver transplantations were performed between January 2013 and December 2020 at Department of Pediatric Organ Transplantation,Tianjin First Central Hospital.The clinical data were collected and a retrospective study was conducted.The recipients and the donors were divided into non-steatotic donor liver group(n=733) and steatotic donor liver group(n=81) according to whether the donor graft had steatosis. The recipients and the donors in the steatotic donor liver group were further divided into mild and moderate steatosis groups based on the degree of liver steatosis.Among the donors of non-steatosis donor group,there were 307 males and 426 females,with a median age of 30 years(range:18 to 57 years);the recipients included 351 males and 382 females,with a median age of 7 months(range:4 month to 14 years).Among the donors of steatosis donor group,there were 41 males and 40 females,with a median age of 31 years(range:22 to 51 years);the recipients included 34 males and 47 females,with a median age of 8 months(range:5 months to 11 years).The donors and the recipients were followed up regularly by means of outpatient reexamination and questionnaire survey after operation.Statistical analysis of data between groups was performed using t-test,Wilcoxon rank-sum test,repeated measures ANOVA,χ2 test,or Fisher's exact test,respectively.The survival curves of recipients and grafts in different groups were created by Kaplan-Meier method,and the survival rates of the steatotic donor liver group and the non-steatotic donor liver group were compared by Log-rank method. Results: There was no significant difference in the gender of donors in both groups (P=0.132).There were significant differences in the age and blood type distribution as well as body weight and body mass index(all P<0.05) between the two groups.No significant difference was seen in the recovery of liver function markers ALT and AST at 1,2,5 days and 1 month after operation (all P>0.05) between the two groups.The steatotic donor liver group showed longer operation time ((294±75) minutes vs. (264±81) minutes; t=3.149,P=0.002),increased incidence of postoperative biliary leakage (3.7%(3/81) vs. 0.5% (4/733); P=0.025) and delayed incision healing (7.4%(6/81) vs. 2.0%(15/733); P=0.013).There were no significant differences in gender,age,blood type distribution,height,weight and pediatric end-stage liver disease score of recipients between the two groups (all P>0.05).As compared to the non-steatotic donor liver group,the steatotic donor liver group showed similar levels of ALT, AST and total bilirubin within 2 weeks after operation(all P>0.05). The cumulative recipient survival rates in both groups were both 96.3%,the cumulative graft survival rates were 96.3% and 95.5%,respectively,without significant difference(both P>0.05). No statistical difference was observed in the incidence of major complications between the two groups (all P>0.05). There was no significant difference in the recovery of liver function markers of donors and recipients between mild and moderate steatosis groups(all P>0.05).The cumulative recipient survival rates were both 95.9% and the cumulative graft survival rates were both 100% in mild and moderate steatosis groups,without significant difference(P=0.592). Conclusions: The application of mild to moderate steatotic donor livers in pediatric living donor liver transplantation may prolong the operation time of donors,increase the incidence of complications such as biliary leakage and delayed incision healing. But there is no significant impact of mild to moderate steatotic donor livers on the overall postoperative recovery of donors and recipients,and the prognosis is ideal.

Abstract
Rising temperature affects microbial composition and function in agriculture field, especially under nitrogen fertilization. In this study, we investigated the bacterial community of paddy soil incubated at controlled temperatures (5 °C, 15 °C, 25 °C, and 35 °C). Results showed that the response of bacterial communities to temperature was not uniform. Temperature elevation from 15 to 25 °C abruptly shifted the soil bacterial community, whereas elevation from 5 to 15 °C and from 25 to 35 °C had a marginal effect. The bacterial α-diversity was higher at 5 °C and 15 °C, owing to the massively distributed taxa with low abundance. However, as the temperature increased to 25 °C and 35 °C, these taxa were diminished, whereas Firmicutes significantly increased, resulting in a strong decline in α-diversity. Simultaneously, bacterial network complexity significantly increased at 25 °C and 35 °C, indicating the bacteria had closer interactions. Nitrogen application aggravated the variation in bacterial diversity and network complexity among temperatures. Interestingly, most complex network was observed under higher temperatures in fertilized soils. Collectively, these results indicate that nitrogen exacerbates the response of the soil bacterial community to temperature, and association between diversity and network complexity may be present.

Abstract
PURPOSE Fibrosis is the only histological feature reflecting the severity and prognosis of nonalcoholic steatohepatitis (NASH). We aim to explore novel genes associated with fibrosis progression in NASH. METHODS Two human RNA-seq datasets were downloaded from the public database. Weighted gene co-expression network analysis (WGCNA) was used to identify their co-expressed modules and further bioinformatics analysis was performed to identify hub genes within the modules. Finally, based on two single-cell RNA-seq datasets from mice and one microarray dataset from human, we further observed the expression of hub genes in different cell clusters and liver tissues. RESULTS 7 hub genes (SPP1, PROM1, SOX9, EPCAM, THY1, CD34 and MCAM) associated with fibrosis progression were identified. Single-cell RNA-seq analysis revealed that those hub genes were expressed by different cell clusters such as cholangiocytes, natural killer (NK) cells, and hepatic stellate cells (HSCs). We also found that SPP1 and CD34 serve as markers of different HSCs clusters, which are associated with inflammatory response and fibrogenesis, respectively. Further study suggested that SPP1, SOX9, MCAM and THY1 might be related to NASH-associated hepatocellular carcinoma (HCC). Receiver operating characteristic (ROC) analysis showed that the high expression of these genes could well predict the occurrence of HCC. At the same time, there were significant differences in metabolism-related pathway changes between different HCC subtypes, and SOX9 may be involved in these changes. CONCLUSIONS The present study identified novel genes associated with NASH fibrosis and explored their effects on fibrosis from a single-cell perspective that might provide new ideas for the early diagnosis, monitoring, evaluation, and prediction of fibrosis progression in NASH.

Abstract
Background Gut microbes degrade and ferment resistant starch (RS) into metabolites that help maintain gut homeostasis. Clinical trials have evaluated RS for various health conditions, but individuals respond to RS with profound variability. The reason for this variability is unclear. Aims Using in vitro culturing methods and multi-omic analyses, we hypothesize that individuals will elicit variable responses to RS with respect to overall fermentation, bacterial composition, short chain acid production, and metabolite flux. Methods As part of an ongoing clinical trial, we have selected 4 pediatric patients with inflammatory bowel disease to better understand microbiome-RS interactions. We cultured stools anaerobically using a high-throughput platform (“RapidAIM”) with 9 different pre-digested RS. After 18-hour incubations, media supernatants were used to measure pH and perform targeted and semi-targeted metabolomic analyses with a panel of 116 compounds. Bacterial pellets were isolated for 16S rRNA gene sequencing analyses to evaluate changes in microbiome compositions. Data were analyzed with generalized linear mixed models, principal component analysis (PCA), random forest (RF) classification with feature selection, and network construction with graphical lasso. Results Changes in several microbiome parameters were different across individuals, including the magnitude of pH changes, metabolite signatures, and relative abundances of important bacterial taxa. Bacterial species known to degrade RS were more abundant in individuals showing stronger RS fermentation. Inter-individual discrimination was accomplished with PCA and RF, from which we could identify metabolite signatures. The robustness of microbiome networks corresponded to RS fermentation and butyrate production. Conclusions We report a novel perspective on how individuals respond to RS’ differently. Butyrate remains an important hub of the microbiome architecture with respect to RS fermentation. Future work will interrogate the roles of individualized metabolomic responses on host physiology. In vivo responses to RS are being evaluated in an ongoing clinical trial. Funding Agencies CCC, CIHRGenome Ontario, Genome Canada

MATERIALS AND METHODS A total of 104 patients with infected focal liver lesions and 485 patients with malignant hepatic tumours were included, consisting of hepatocellular carcinoma (HCC), cholangiocarcinoma (CC), combined hepatocellular-cholangiocarcinoma (cHCC-CC), and liver metastasis. Radiomics features were extracted from grey-scale ultrasound images. Feature selection and predictive modelling were carried out by dimensionality reduction methods and classifiers. The diagnostic effect of the prediction mode was assessed by receiver operating characteristic (ROC) curve analysis. RESULTS In total, 5,234 radiomics features were extracted from grey-scale ultrasound image of every focal liver lesion. The ultrasound-based radiomics model had a favourable predictive value for differentiating infected focal liver lesions from malignant hepatic tumours, with an area under the curve (AUC) of 0.887 and 0.836 (HCC group), 0.896 and 0.766 (CC group), 0.944 and 0.754 (cHCC-CC group), 0.918 and 0.808 (liver metastasis group), and 0.949 and 0.745 (malignant hepatic tumour group) for the training set and validation set, respectively. CONCLUSIONS Ultrasound-based radiomics is helpful in differentiating infected focal liver lesions from malignant mimickers and has the potential for use as a supplement to conventional grey-scale ultrasound and contrast-enhanced ultrasound (CEUS).

Abstract
Background: Alzheimer's disease (AD) has affected numerous elderly individuals worldwide. Panax notoginseng has been shown to ameliorate AD symptoms, and notoginsenoside R2 is a key saponin identified in this plant. Purpose: In the current study, we aimed to explore whether notoginsenoside R2 could improve the prognosis of AD. Methods: Herein, primary rat cortical neurons were isolated and they were treated with amyloid beta-peptide (Aβ) 25-35 oligomers. Cellular apoptosis was examined via flow cytometry and Western blotting. miR-27a and SOX8 mRNA expression levels were quantified by quantitative reverse transcription-polymerase chain reaction. Furthermore, the interaction between miR-27a and SOX8 was investigated by utilizing a dual-luciferase reporter assay. Finally, an AD mouse model was established to validate the in vitro findings. Results: Notoginsenoside R2 alleviated Aβ25-35-triggered neuronal apoptosis and inflammation. During this process, miR-27a expression was decreased by notoginsenoside R2, and miR-27a negatively modulated SOX8 expression. Furthermore, activation of SOX8 upregulated β-catenin expression, thus suppressing apoptosis and neuroinflammation. Conclusions: Our animal experiments revealed that notoginsenoside R2 enhanced the cognitive function of AD mice and inhibited neuronal apoptosis. Notoginsenoside R2 ameliorated AD symptoms by reducing neuronal apoptosis and inflammation, thus suggesting a novel direction for AD pharmacotherapy.

Abstract
High yields and environment-related issues because of over-fertilization in rice (Oryza sativa L.) production is a major concern in China. Partial replacement of mineral fertilizer (MF) with organic matter is considered a win-win approach for resource-saving and environmentally friendly rice production. Here, we examined the effects of reduced MF and in situ crop residue on the rice yield and soil fertility in the long term. A 27-year field experiment (a randomized block design with three replicates) in subtropical China was conducted to test the feasibility of the substitution in a double rice paddy ecosystem. The treatments were CT (no fertilizer application considered as control), NPK (mineral fertilizer N, P, and K), and RFC (reduced MF and in situ crop residue to supplement the reduced NPK dose). The crop residue included half of the rice straw and green manure contents, which were retained in situ in the RFC treatment. The RFC maintained the same rice yield and soil fertility levels as NPK. In general, soil organic carbon (SOC) and total nitrogen (TN) content in RFC increased by 10.3% -20.8%, and 7.5% -28.0%, respectively, than that in NPK from the 5th to the 25th years. There was no significant difference in the content and net accumulation of SOC, TN, and TP and soil available nutrients between the RFC and NPK treatments after 25 years. The average annual yields were 9690 and 9872 kg ha-1 for the NPK and RFC treatments, respectively. There was no difference in the yield of the first, second, and annual rice crops between RFC and NPK in most years (six of the fifty-four seasons showed a significant difference). RFC increased the partial factor productivity (PFP), agronomic efficiency (AE) of MF, and yield stability (CV) (p < 0.05). Positive nutrient balance and a reduced loss of nutrients are evident reasons for achieving better indicators (PFP, AE, and CV) for nutrient compensation and organic nutrient utilization in the RFC treatment. The partial replacement of MF with in situ crop residue retention, is a simple and efficient way to maintain the soil fertility and rice yield as NPK in southern China.

Abstract
Magnonics is a budding research field in nanomagnetism and nanoscience that addresses the use of spin waves (magnons) to transmit, store, and process information. The rapid advancements of this field during last one decade in terms of upsurge in research papers, review articles, citations, proposals of devices as well as introduction of new sub-topics prompted us to present the first roadmap on magnonics. This is a collection of 22 sections written by leading experts in this field who review and discuss the current status besides presenting their vision of future perspectives. Today, the principal challenges in applied magnonics are the excitation of sub-100 nm wavelength magnons, their manipulation on the nanoscale and the creation of sub-micrometre devices using low-Gilbert damping magnetic materials and its interconnections to standard electronics. To this end, magnonics offers lower energy consumption, easier integrability and compatibility with CMOS structure, reprogrammability, shorter wavelength, smaller device features, anisotropic properties, negative group velocity, non-reciprocity and efficient tunability by various external stimuli to name a few. Hence, despite being a young research field, magnonics has come a long way since its early inception. This roadmap asserts a milestone for future emerging research directions in magnonics, and hopefully, it will inspire a series of exciting new articles on the same topic in the coming years.

Abstract
Objectives: To study the risk factors for massive intraoperative blood loss in children with biliary atresia who underwent liver transplantation for the first time,and to analyze their impacts on graft survival,hospital stay and postoperative complications. Methods: The data of 613 children with biliary atresia who underwent liver transplantation at Department of Pediatric Organ Transplantation,Tianjin First Central Hospital from January 2015 to December 2018 were collected and analyzed. There were 270 males and 343 females, aged 7.4 (3.9) months (range: 3.2 to 148.4 months), the body weight of the recipients were (7.8±3.5) kg (range: 4.0 to 43.3 kg).According to the 85th quad of estimated blood loss(EBL),they were divided into two groups:massive EBL group(96 cases) and non massive EBL group(517 cases). The age,height,weight and other factors between the two groups were analyzed and compared. Univariate Logistic regression and multiple stepwise regression were used to determine the risk factors of massive EBL. Then,the postoperative complications of the two groups,including portal vein thrombosis and portal vein anastomotic stenosis etc.,were analyzed and compared by chi square test. Kaplan Meier curve and log rank test were used to analyze the recipient and graft survival rate of the two groups. Results: During the study period,713 transplants were performed and 613 patients were enrolled in the study. Ninety-six patients(15.7%) had massive EBL,and the postoperative hospital stay was 21(16) days(range:2 to 116 days),the hospital stay of non-massive EBL group was 22(12)days(range:3 to 138 days)(U=24 224.0,P=0.32). Univariate Logistic regression analysis showed that the recipient's weight,Kasai portoenterostomy,platelet count,operation time and cold ischemia time were the risk factors of massive EBL during biliary atresia transplantation. Multiple regression analysis showed that cold ischemia time ≥10 hours,prolonged operation time(≥8 hours) and body weight<5.5 kg were important independent risk factors for massive EBL.The incidence of portal vein thrombosis,hepatic vein stenosis,intestinal leakage and pulmonary infection in patients with massive EBL were significantly higher than those without massive EBL(3.1% vs. 0.8%,9.4% vs. 2.1%,6.3% vs. 0.8%,30.2% vs. 20.1%,all P<0.05). The 3-year overall graft and recipient survival rate were significantly lower in patients with massive EBL than those without massive EBL(87.5% vs. 95.7%,P=0.001;84.4% vs. 95.4%,P<0.01,respectively). Conclusions: In children with biliary atresia who underwent liver transplantation for the first time,the effective control of intraoperative bleeding should shorten the operation time and reduce the cold ischemia time as far as possible,on the premise of ensuring the safety of operation. For children without growth disorder,the weight of children should be increased to more than 5.5 kg as far as possible to receive the operation. Reducing intraoperative bleeding is of great significance to the prognosis of children.

Abstract
For liquid–porous material interactions (LPMI), three variational principles are developed in Biot's theory of porous materials in association with Darcy's Law. First one takes solid acceleration, and fluid velocity, acceleration, pressure with time derivative as five variables, while second and third, respectively, have three and two variables when Darcy's Law used as variational constraint reducing variables. These principles provide a means to derive approximate solutions and finite-element (FE) models for LPMI. Each LPMI element includes fluid and solid together with it being no longer necessary to distinguish fluid domain from solid. Examples illustrate applications to establish FE model for numerical solutions of LPMI. Solution of a one-dimensional problem reveals that LPMI behaves a coupled-frequency separation measured by a defined-coupling factor. Dynamic response explores coupled-dynamic absorber mechanism in LPMI system, from which it is found that the external force at fluid does not contribute to fluid response but fully absorbed by solid local resonance if the force frequency equals the solid natural frequency; while in the reverse case when the force frequency equals the fluid one, the force at solid does not produce the solid response but fully absorbed by fluid local resonance. New findings with defined LPMI coupling factor provide guidelines for designing LPMI system with expected dynamic behaviour meeting engineering requirements.

Abstract
OBJECTIVE Lung cancer is one of the most malignant tumors with high morbidity and mortality in the world. The incidence and mortality of lung cancer were increased per year in many countries over the past 50 years. The increasing studies had shown that circular RNA (circRNA) was involved in the progression of lung cancer. Therefore, it was significant to seek the molecular mechanism of circ_0012673 in lung cancer. MATERIALS AND METHODS Real-time quantitative polymerase chain reaction (RT-qPCR) was performed to estimate the expression levels of circ_0012673, miR-320a and LIM domain kinase 1 (LIMK1) in lung cancer tissues and cells. 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazol-3-ium bromide (MTT), flow cytometry and transwell assays were recruited to evaluate proliferation, apoptosis and mobility of lung cancer cells, respectively. The relative protein expression levels of Vimentin, N-cadherin, E-cadherin and LIMK1 were determined with Western blot assay. The relationships among circ_0012673, miR-320a and LIMK1 were analyzed by starBase database, dual-luciferase reporter assay, and Pearson's correlation. RESULTS Circ_0012673 was overexpressed in lung cancer tissues and cell lines. Loss-of-functional experiment confirmed that knockdown of circ_0012673 constrained proliferation, motility and Epithelial-Mesenchymal Transition (EMT), but induced apoptosis by targeting miR-320a. Furthermore, LIMK1 was a target of miR-320a in lung cancer cells. Elevated LIMK1 could abolish the overexpression of miR-320a induced effects on lung cancer cells. Mechanistically, circ_0012673 contributed to lung cancer progression through mediating miR-320a /LIMK1 pathway. CONCLUSIONS Circ_0012673 was a tumor-promoter in lung cancer via acting as competing endogenous RNA to regulate LIMK1 expression by binding miR-320a.

Abstract
Cerebral ischemia is the most common cause of hippocampal neuronal death and the most prevalent cause of stroke with high mortality rate. Ferroptosis has been suggested to affect the role of hippocampal neurons. This study explores the influence of lentivirus infection-induced ferritin overexpression in hippocampal neuronal injury and death through simulations in August Copenhagen Irish rat models. Twenty-four-hour cerebral ischemia-reperfusion injury was induced in the rats after 90-min middle cerebral artery occlusion (MCAO). Ferritin overexpression was induced through lentivirus infection. The Morris Water Maze (MWM) test and tau hyperphosphorylation test were performed on hippocampal neurons to establish a MCAO model. The effect of ferritin overexpression on hippocampal neuronal death was evaluated using hematoxylin-eosin staining and annexin V/propidium iodide flow cytometry. The MWM test revealed that MCAO modeling decreased the cognitive and locomotor capacity of the rats, whereas ferritin overexpression partially reversed the effect of MCAO. In addition, the hyperphosphorylation of tau caused by MCAO was reduced by ferritin. Pathogenic changes, impaired viability, increased apoptosis, and elevated caspase-9 cleavage in hippocampal neurons were clearly recovered by ferritin. Moreover, robust reactive oxygen species production and glutathione consumption, which was induced by MCAO modeling, were ameliorated by ferritin. Furthermore, two key modulators of ferroptosis, p53 and SLC7A11, were demonstrated to be upregulated by MCAO modeling and downregulated by ferritin. Ferritin reduction is essential for cerebral ischemia-induced hippocampal neuronal ferroptosis mediated via p53 and SLC7A11.

Abstract
Biological nitrogen (N2) fixation as a source of new N input into the soil by free-living diazotrophs is important for achieving sustainable rice agriculture. However, the dominant environmental drivers or factors influencing N2 fixation and the functional significance of the diazotroph community structure in paddy soil across a climatic gradient are not yet well understood. Thus, we characterized the diazotroph community and identified the ecological predictors of N2 fixation potential in four different climate zones (mid-temperate, warm-temperate, subtropical, and tropical paddy soils) in eastern China. Comprehensive nifH gene sequencing, functional activity detection, and correlation analysis with environmental factors were estimated. The potential nitrogenase activity (PNA) was highest in warm-temperate regions, where it was 6.2-, 2.9-, and 2.2-fold greater than in the tropical, subtropical, and mid-temperate regions, respectively; nifH gene abundance was significantly higher in warm-temperate and subtropical zones than in the tropical or mid-temperate zones. Diazotroph diversity was significantly higher in the tropical climate zone and significantly lower in the mid-temperate zone. Non-metric multidimensional scaling and canonical correlation analysis indicated that paddy soil diazotroph populations differed significantly among the four climate zones, mainly owing to differences in climate and soil pH. Structural equation models and automatic linear models revealed that climate and nutrients indirectly affected PNA by affecting soil pH and diazotroph community, respectively, while diazotroph community, C/P, and nifH gene abundance directly affected PNA. And C/P ratio, pH, and the diazotroph community structure were the main predictors of PNA in paddy soils. Collectively, the differences in diazotroph community structure have ecological significance, with important implications for the prediction of soil N2-fixing functions under climate change scenarios.

Abstract
Objective: To summarize the clinical characteristics of high-risk neuroblastoma (HR-NB) in a single center, analyze the prognostic factors of HR-NB. Methods: The clinical data of children with HR-NB who were treated and followed up at the hematology-oncology center of Beijing Children's Hospital from February 1, 2007 to June 30, 2018 were analyzed retrospectively. The clinical features were summarized. Kaplan-Meier method was used for survival analysis and Cox regression was used to analyze the prognostic factors. The last follow-up time was June 30, 2019. Results: A total of 458 children with HR-NB were enrolled in this study, including 265 males (57.9%) and 193 females (42.1%), the age at diagnosis was 40.0 months (4.5-148.0 months), the follow-up time was 22.0 months (0.2-138.0 months) and the time of tumor progression or recurrence was 15 months (1-72 months). The 5-year event-free survival (EFS) rate was (31.2±2.6)% and the 5-year overall survival (OS) rate was (43.9±3.2)%. The 5-year EFS rate and 5-year OS rate in 142 hematopoietic stem cell transplantation (HSCT) patients with bone marrow metastases were better than that in 196 non-transplantation cases with bone marrow metastases ((26.5±4.5)% vs. (25.1±3.6)%, χ²=13.773, P=0.001; (38.1±5.5)% vs. (35.7±4.7)%, χ²=9.235, P=0.002); 128 transplantation patients with bone metastases had higher 5-year EFS rate and 5-year OS rate than 188 non-transplantation cases with bone metastases ((28.5±5.0)% vs. (26.7±3.8)%, χ²=10.222, P=0.001; (37.1±6.0)% vs. (36.2±4.8)%, χ²=7.843, P=0.005). The 5-year EFS rate was higher in 37 HSCT patients with MYCN amplification than in 49 non-transplantation cases with MYCN amplification ((26.8±8.0) % vs. (20.5±6.4) %, χ²=5.732, P=0.017). No significant difference was found in 5-years OS rate between transplantation group with MYCN amplification and non-transplantation group with MYCN amplification ((31.4±8.6) % vs. (26.2±7.4) %, χ²=3.230, P=0.072). Univariate survival analysis showed that lactate dehydrogenase (LDH)≥1 500 U/L was associated with poor prognosis of patients with MYCN amplification (χ²=6.960, P=0.008). Multivariate Cox analysis showed bone marrow metastasis and LDH≥1 500 U/L were independent risk factors for poor prognosis of patients with non-MYCN amplification (HR=2.427, 1.618;95%CI:1.427-4.126, 1.275-2.054, P<0.05) for both comparisons. Conclusions: LDH≥1 500 U/L was the poor prognostic factor for patients with MYCN amplification. The bone marrow metastasis and LDH≥1 500 U/L were the poor prognostic factors for HR-NB patients with non-MYCN amplification. HSCT can improve the prognosis of patients with bone or bone marrow metastasis. It can also retard the time of progression or recurrence for patients with MYCN amplification.

Abstract
AIMS Mitochondrial dysfunction is involved in the pathogenesis of type 2 diabetes. Glutathione S-transferase kappa 1 (GSTK1) is critical to maintain mitochondrial function and homeostasis. We aimed to investigate whether a potential link exists between mitochondrial DNA (mtDNA) copy numbers and inflammation, non-esterified fatty acids (NEFA) and GSTK1 expression in type 2 diabetes. METHODS We assessed mtDNA copy numbers in plasma and GSTK1 expression in white blood cells in 123 people with type 2 diabetes and in 121 healthy controls using a quantitative polymerase chain reaction (qPCR). An automatic chemistry or immunoassay analyser was used to determine serum glucose, lipids and inflammatory markers. Multiple linear regression and multivariable logistic regression models were used to evaluate associations and risks. RESULTS Compared with healthy controls, individuals with diabetes showed higher mtDNA copy numbers (t = -3.938, P < 0.001) and lower GSTK1 expression (Z = -2.985, P = 0.002). mtDNA copy number was associated with type 2 diabetes risk [odds ratio (OR) = 1.80, 95% confidence intervals (CI) 1.25-2.58, P = 0.001] after controlling for confounding factors. In individuals with diabetes, mtDNA copy number was negatively associated with GSTK1 expression (β = -0.235, P = 0.036) and positively associated with serum high-sensitive C-reactive protein (hsCRP) (β = 0.839, P < 0.001), tumour necrosis factor alpha (TNF-α) (β = 0.549, P < 0.001), interleukin-6 (IL-6) (β = 0.589, P = 0.006) and NEFA (β = 0.001, P = 0.020). In the diabetic group, individuals with an abnormal increase in NEFA, hsCRP, TNF-α and IL-6 showed significantly elevated mtDNA copy numbers (all P < 0.05). CONCLUSIONS mtDNA copy numbers in plasma might have an important role in the progression of diabetic chronic inflammation via inhibition of GSTK1 and could be a potential biomarker for type 2 diabetes.

Abstract
The pyruvate oxidase (SpxB)-dependent production of H2O2 is widely distributed among oral commensal streptococci. Several studies confirmed the ability of H2O2 to antagonize susceptible oral bacterial species, including caries-associated Streptococcus mutans as well as several periodontal pathobionts. Here we report a potential mechanism to bolster oral commensal streptococcal H2O2 production by magnesium (Mg2+) supplementation. Magnesium is a cofactor for SpxB catalytic activity, and supplementation increases the production of H2O2 in vitro. We demonstrate that Mg2+ affects spxB transcription and SpxB abundance in Streptococcus sanguinis and Streptococcus gordonii. The competitiveness of low-passage commensal streptococcal clinical isolates is positively influenced in antagonism assays against S. mutans. In growth conditions normally selective for S. mutans, Mg2+ supplementation is able to increase the abundance of S. sanguinis in dual-species biofilms. Using an in vivo biophotonic imaging platform, we further demonstrate that dietary Mg2+ supplementation significantly improves S. gordonii oral colonization in mice. In summary, our results support a role for Mg2+ supplementation as a potential prebiotic to promote establishment of oral health-associated commensal streptococci.

Abstract
Objective: To study the protective effect and potential mechanism of heme oxygenase (HO-1)/carbon monoxide (CO)-mediated quercetin on alcoholic oxidative damage of primary rat hepatocytes. Methods: Primary rat hepatocytes were isolated and cultured by two-step collagenase technique. Ethanol exposed primary rat hepatocytes were simultaneously added with quercetin (100 μmol/L) and/or hemoglobin (100 μmol/L) or different doses of CO-releasing molecules (CORM-2, 5-50 μmol/L) for their combined action. After polling, LDH, AST activities and MDA and GSH levels were measured in the supernatant of cell culture. The alone or combined effects of quercetin, CORM-2, hemoglobin and zinc protoporphyrin IX exposed to ethanol were detected by the activity of CYP2E1 in liver microsomes. Statistical analysis of data was performed by analysis of variance (ANOVA) and intergroup comparison was done by SNK-test. Results: Simultaneous addition of 100 μmol/L quercetin had significantly reduced ethanol-induced AST and LDH release, and GSH consumption and MDA elevation extent. Moreover, quercetin had not only lost the hemoglobin (CO blocker) protective effect but also had further exacerbated ethanol-induced lipid peroxidation. CORM-2 had reduced ethanol-induced AST and LDH release, and GSH consumption and MDA production in liver cells, and thus had dose-dependent protective effect. Ethanol had increased significantly CYP2E1 activity. Quercetin or CORM-2 had inhibited CYP2E1 activity, while hemoglobin or protoporphyrin IX had eliminated quercetin inhibitory effect and had increased the CYP2E1 activity. Quercetin, and CYP2E1 activity was constant as compared to ethanol group when CORM-2, zinc protoporphyrin IX and ethanol were incubated with hepatocytes, but the CYP2E1 activity was significantly decreased (P < 0.05), and the differences were statistically significant. Conclusion: CO/HO-1 metabolite mediates the protective effect of quercetin on alcoholic oxidative damage of hepatocytes, which may be related to the inhibition of CYP2E1 activity.

Abstract
Inspired by the gas-trapped mechanism underwater of Argyroneta aquatica, we prepared a superhydrophobic yarn with a fiber network structure via a facile and environmentally friendly method. Attributed to the low surface energy, the superhydrophobic fiber network structure on the yarn is able to trap and transport bubbles directionally underwater. The functional yarn has good superhydrophobic and superaerophilic properties underwater to realize the directional transport of bubbles underwater without being pumped. We designed demonstration experiments on the antibuoyancy directional bubble transportation, which indicated the feasibility in the applications of gas-related fields. Significantly, on further testing, where the superhydrophobic yarn is put into a U-shaped pipe, we obtain a gas-siphon underwater with a high flux. The superhydrophobic fiber structure yarn can trap the gas underwater to enable the self-starting behavior while no manual intervention is used. The gas-siphon can convey gas over the edge of a vessel and deliver it at a higher level without energy input, which is driven by the differential pressure. The relationship between the differential pressure and the volume flux of transport bubbles is investigated. The experimental results show that the prepared superhydrophobic yarn has the advantages of good stability, easy preparation, and low cost in bubble continuous transportation underwater, which provides a novel strategy for the development and application of new technologies such as directional transportation, separation, exhaustion, and collection of gases in water.

Abstract
AIM To investigate the effect of radiomics in the assessment of alterations in canonical cancer pathways in breast cancer. MATERIALS AND METHODS Eighty-eight biopsy-proven breast cancer cases were included in the present study. Radiomics features were extracted from T1-weighted sagittal dynamic contrast-enhanced magnetic resonance imaging (MRI) images. Radiomics signatures were developed to predict genetic alterations in the cell cycle, Myc, PI3K, RTK/RAS, and p53 signalling pathways by using hypothesis testing combined with least absolute shrinkage and selection operator (LASSO) regression analysis. The predictive powers of the models were examined by the area under the curve (AUC) of the receiver operating characteristic curve. RESULTS A total of 5,234 radiomics features were obtained from MRI images based on the tumour region of interest. Hypothesis tests screened 250, 229, 156, 785, and 319 radiomics features that were differentially displayed between cell cycle, Myc, PI3K, RTK/RAS, and p53 alterations and no alteration status. According to the LASSO algorithm, 11, 12, 12, 15, and 13 features were identified for the construction of the radiomics signatures to predict cell cycle, Myc, PI3K, RTK/RAS, and p53 alterations, with AUC values of 0.933, 0.926, 0.956, 0.940, and 0.886, respectively. The cell cycle radiomics score correlated closely with the RTK/RAS and p53 radiomics scores. These signatures were also dysregulated in patients with different oestrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 statuses. CONCLUSION MRI-based radiogenomics analysis exhibits excellent performance in predicting genetic pathways alterations, thus providing a novel approach for non-invasively obtaining genetic-level molecular characteristics of tumours.
