Abstract
Objective: Explore the association between atrial fibrillation (AF) reoccurrence and new-onset ischemic stroke (IS) in patients with nonvalvular AF, and explore whether there is a high-risk period of IS after recurrent episodes of AF. Methods: A nested case-control study design was used. A total of 565 nonvalvular AF patients with new-onset IS after a follow-up of at least 2 years in the China-AF cohort were enrolled as the case group, and 1 693 nonvalvular AF patients without new-onset IS were matched as the control group at a ratio of 1∶3. Frequency and types of recurrent AF in the previous 1 or 2 years were compared between two groups, and the adjusted associations of AF reoccurrence with new onset IS were explored using conditional logistic regression analysis. The proportion of recurrent AF was compared between the case period and control period, and conditional logistic regression analysis was performed to calculate adjusted associations of case-period AF with IS. Results: The nested case-control study design results showed that the proportion of at least one record of recurrent AF in the previous 1 year was higher in the case group than in the control group (72.0% vs. 60.8%, P<0.05), and the recurrent AF was positively correlated with new-onset IS (adjusted OR=1.80, P<0.001). Similar results were also observed in the previous 2 years period. The case-crossover study design analysis showed that among 565 patients with new-onset IS, recurrent AF in the case period was positively correlated with IS (adjusted OR=1.61, P=0.003). Conclusion: Recurrent AF is associated with IS, and there may be a high-risk period of IS after recurrent episodes of AF.

Abstract
Objective: To investigate the prevalence of syphilis in HIV-infected patients with transmission risk and influencing factors in Zhejiang Province. Method: The information about the HIV-infected patients, who were alive, had been diagnosed with HIV for >1 year, had received no antiviral treatment or had HIV viral load ≥50 copies/ml, and were aged ≥15 years, reported in Zhejiang as of December 31, 2018 were collected from China Information System for Disease Control and Prevention. The information included general demographic characteristics, sexual behavior characteristics and antiretroviral therapy and syphilis serological test results. The prevalence of syphilis and the influencing factors were analyzed by logistic regression model. The SPSS 19.0 software was used for statistical analysis. Results: A total of 2 275 HIV-infected patients were at risk of HIV transmission, and 75.5% (1 717/2 275) of them were tested for syphilis, the prevalence rate of syphilis was 8.7% (150/1 717). Among the HIV-infected patients with syphilis, 11.3% (17/150) received no antiviral treatment, 38.7% (58/150) had viral load of 50-999 copies/ml and 50.0% (75/150) had ≥1 000 copies/ml. Multivariate logistic regression analysis showed that being men (aOR=2.04, 95%CI:1.06-3.96), homosexual transmission (aOR=1.53, 95%CI:1.04-2.27), history of sexually transmitted diseases (STDs) before HIV diagnosis (aOR=1.98, 95%CI:1.35-2.92) and HIV viral load ≥1 000 copies/ml (aOR=1.90, 95%CI:1.09-3.30) were the risk factors for syphilis. Marriage (aOR=0.47, 95%CI: 0.29-0.76) was a protective factor for syphilis. Conclusions: The prevalence of syphilis was high in HIV-infected patients with transmission risk in Zhejiang. It is urgent to carry out classified management and targeted intervention in HIV-infected patients, explore multi-disease prevention and treatment mechanism, strengthen syphilis screening and treatment in HIV-infected patients to reduce the transmission of HIV and syphilis.

Abstract
Background Cervical spondylopathy is a common musculo-articular disorder, multiple exercises are recommended. Chinese fitness exercises are prevalent and used to treat various diseases. Aim To explore the efficacy of Chinese fitness exercise Yi Jin Jing exercise in intervening the cervical spondylopathy in adolescents. Patients and Methods The study was conducted in 60 adolescent patients with cervical spondylopathy, with 30 patients in each group. Methods The study was conducted in 60 adolescent patients with cervical spondylopathy, with 30 patients in each group. The observation group was required to take Yi Jin Jing exercise, and the control group took the brisk walking exercise. The first week was the preparatory period for the patients, and then the participants were required to do exercises three times a week for at least 30 minutes in the later 3 weeks. Before and after treatment, Neck Disability Index (NDI) scores, pain visual analog scale (VAS) scores, and cervical curvature in both groups were observed, and the incidence of adverse events in both groups was recorded during the trial. Results The NDI and VAS scores in both groups statistically decreased after intervention and mildly increased at follow-up, while the reduction in scores of the Yi Jin Jing group was more significant. Cervical curvature in both groups improved on day 28 compared to day 0. There were no adverse reactions during the evaluation period. Conclusion The Chinese health-care qigong Yi Jin Jing exercise is more effective than brisk walking in improving the cervical range of motion and relieving pain in adolescents with cervical spondylopathy.

Abstract
Background & Aims HBV-related acute-on-chronic liver failure (HBV-ACLF) is a complex syndrome associated with high short-term mortality. This study aims to reveal the molecular basis and identify novel HBV-ACLF biomarkers. Methods Seventy patients with HBV-ACLF and different short-term (28 days) outcomes underwent transcriptome sequencing using peripheral blood mononuclear cells. Candidate biomarkers were confirmed in two external cohorts using ELISA. Results Cellular composition analysis with peripheral blood mononuclear cell transcriptomics showed that the proportions of monocytes, T cells and natural killer cells were significantly correlated with 28-day mortality. Significant metabolic dysregulation of carbohydrate, energy and amino acid metabolism was observed in ACLF non-survivors. V-set and immunoglobulin domain-containing 4 (VSIG4) was the most robust predictor of patient survival (adjusted p = 1.74 × 10-16; variable importance in the projection = 1.21; AUROC = 0.89) and was significantly correlated with pathways involved in the progression of ACLF, including inflammation, oxidative phosphorylation, tricarboxylic acid cycle and T-cell activation/differentiation. Plasma VSIG4 analysis externally validated its diagnostic value in ACLF (compared with chronic liver disease and healthy groups, AUROC = 0.983). The prognostic performance for 28-/90-day mortality (AUROCs = 0.769/0.767) was comparable to that of three commonly used scores (COSSH-ACLFs, 0.867/0.884; CLIF-C ACLFs, 0.840/0.835; MELD-Na, 0.710/0.737). Plasma VSIG4 level, as an independent predictor, could be used to improve the prognostic performance of clinical scores. Risk stratification based on VSIG4 expression levels (>122 μg/ml) identified patients with ACLF at a high risk of death. The generality of VSIG4 in other etiologies was validated. Conclusions This study reveals that immune-metabolism disorder underlies poor ACLF outcomes. VSIG4 may be helpful as a diagnostic and prognostic biomarker in clinical practice. Impact and implications Acute-on-chronic liver failure (ACLF) is a lethal clinical syndrome associated with high mortality. We found significant immune cell alterations and metabolic dysregulation that were linked to high mortality in patients with HBV-ACLF based on transcriptomics using peripheral blood mononuclear cells. We identified VSIG4 (V-set and immunoglobulin domain-containing 4) as a diagnostic and prognostic biomarker in ACLF, which could specifically identify patients with ACLF at a high risk of death.

Abstract
Objective: To analyze the status of statins use and low-density lipoprotein cholesterol (LDL-C) management in patients with atrial fibrillation (AF) and very high/high risk of atherosclerotic cardiovascular disease (ASCVD) from Chinese Atrial Fibrillation Registry (CAFR). Methods: A total of 9 119 patients with AF were recruited in CAFR between January 1, 2015 to December 31, 2018, patients at very high and high risk of ASCVD were included in this study. Demographics, medical history, cardiovascular risk factors, and laboratory test results were collected. In patients with very high-risk, a threshold of 1.8 mmol/L was used as LDL-C management target and in patients with high risk, a threshold of 2.6 mmol/L was used as LDL-C management target. Statins use and LDL-C compliance rate were analyzed, multiple regression analysis was performed to explore the influencing factors of statins use. Results: 3 833 patients were selected (1 912 (21.0%) in very high risk of ASCVD group and 1 921 (21.1%) in high risk of ASCVD group). The proportion of patients with very high and high risk of ASCVD taking statins was 60.2% (1 151/1 912) and 38.6% (741/1 921), respectively. Attainment rate of LDL-C management target in patients with very high and high risk were 26.7% (511/1 912) and 36.4% (700/1 921), respectively. Conclusion: The proportion of statins use and attainment rate of LDL-C management target are low in AF patients with very high and high risk of ASCVD in this cohort. The comprehensive management in AF patients should be further strengthened, especially the primary prevention of cardiovascular disease in AF patients with very high and high risk of ASCVD.

Abstract
Background Compared to other subtypes, the CMS4 subtype is associated with lacking of effective treatments and poorer survival rates. Methods A total of 24 patients with CRC were included in this study. DNA and RNA sequencing were performed to acquire somatic mutations and gene expression, respectively. MATH was used to quantify intratumoral heterogeneity. PPI and survival analyses were performed to identify hub DEGs. Reactome and KEGG analyses were performed to analyze the pathways of mutated or DEGs. Single-sample gene set enrichment analysis and Xcell were used to categorize the infiltration of immune cells. Results The CMS4 patients had a poorer PFS than CMS2/3. CTNNB1 and CCNE1 were common mutated genes in the CMS4 subtype, which were enriched in Wnt and cell cycle signaling pathways, respectively. The MATH score of CMS4 subtype was lower. SLC17A6 was a hub DEG. M2 macrophages were more infiltrated in the tumor microenvironment of CMS4 subtype. The CMS4 subtype tended to have an immunosuppressive microenvironment. Conclusion This study suggested new perspectives for exploring therapeutic strategies for the CMS4 subtype CRC.

Abstract
Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is a highly destructive bacterial disease. Traditional prevention methods have utilized antibiotics to target bacterial growth, which has accelerated the emergence of resistant strains. New prevention techniques are developing agents such as type III secretion system (T3SS) inhibitors that target bacterial virulence factors without affecting bacterial growth. To explore novel T3SS inhibitors, a series of ethyl-3-aryl-2-nitroacrylate derivatives were designed and synthesized. Preliminary screening of T3SS inhibitors was based on the inhibition of the hpa1 gene promoter and showed no effect on bacterial growth. Compounds B9 and B10, obtained in the primary screening, significantly inhibited the hypersensitive response (HR) in tobacco and the expression of T3SS genes in the hrp cluster including key regulatory genes. In vivo bioassays showed that T3SS inhibitors obviously inhibited BLB and appeared to be more effective when combined with quorum quenching bacteria F20.

Abstract
Objective: To investigate current use of oral anticoagulant (OAC) therapy and influencing factors among coronary artery disease (CAD) patients with nonvalvular atrial fibrillation (NVAF) in China. Methods: Results of this study derived from "China Atrial Fibrillation Registry Study", the study prospectively enrolled atrial fibrillation (AF) patients from 31 hospitals, and patients with valvular AF or treated with catheter ablation were excluded. Baseline data such as age, sex and type of atrial fibrillation were collected, and drug history, history of concomitant diseases, laboratory results and echocardiography results were recorded. CHA2DS2-VASc score and HAS-BLED score were calculated. The patients were followed up at the 3rd and 6th months after enrollment and every 6 months thereafter. Patients were divided according to whether they had coronary artery disease and whether they took OAC. Results: 11 067 NVAF patients fulfilling guideline criteria for OAC treatment were included in this study, including 1 837 patients with CAD. 95.4% of NVAF patients with CAD had CHA2DS2-VASc score≥2, and 59.7% of patients had HAS-BLED≥3, which was significantly higher than NVAF patients without CAD (P<0.001). Only 34.6% of NVAF patients with CAD were treated with OAC at enrollment. The proportion of HAS-BLED≥3 in the OAC group was significantly lower than in the no-OAC group (36.7% vs. 71.8%, P<0.001). After adjustment with multivariable logistic regression analysis, thromboembolism(OR=2.48,95%CI 1.50-4.10,P<0.001), left atrial diameter≥40 mm(OR=1.89,95%CI 1.23-2.91,P=0.004), stain use (OR=1.83,95%CI 1.01-3.03, P=0.020) and β blocker use (OR=1.74,95%CI 1.13-2.68,P=0.012)were influence factors of OAC treatment. However, the influence factors of no-OAC use were female(OR=0.54,95%CI 0.34-0.86,P=0.001), HAS-BLED≥3 (OR=0.33,95%CI 0.19-0.57,P<0.001), and antiplatelet drug(OR=0.04,95%CI 0.03-0.07,P<0.001). Conclusion: The rate of OAC treatment in NVAF patients with CAD is still low and needs to be further improved. The training and assessment of medical personnel should be strengthened to improve the utilization rate of OAC in these patients.

Abstract
Objectives: To analyze the reasons of missed diagnosis or misdiagnosis on anomalous origin of left coronary artery from pulmonary artery (ALCAPA) by echocardiography. Methods: This is a retrospective study. Patients with ALCAPA who underwent surgical treatment in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from August 2008 to December 2021 were included. According to the results of preoperative echocardiography and surgical diagnosis, the patients were divided into confirmed group or missed diagnosis/misdiagnosis group. The results of preoperative echocardiography were collected, and the specific echocardiographic signs were analyzed. According to the experience of the doctors, the echocardiographic signs were divided into four types, namely clear displayed, vague/doubtful displayed, no display and no notice, and the display rate of each sign was calculated (display rate=number of clearly displayed cases/total number of cases×100%). By referring the surgical data, we analyzed and recorded the pathological anatomy and pathophysiological characteristics of the patients, and the rate of missed diagnosis/misdiagnosis of echocardiography in patients with different characteristics was compared. Results: A total of 21 patients were enrolled, including 11 males, aged 1.8 (0.8, 12.3) years (range 1 month to 47 years). Except for one patient with anomalous origin of left anterior descending artery, the others were all originated from the main left coronary artery (LCA). There were 13 cases of ALCAPA in infant and children, and 8 cases of adult ALCAPA. There were 15 cases in the confirmed group (diagnostic accuracy was 71.4% (15/21)), and 6 cases in the missed diagnosis/misdiagnosis group (three cases were misdiagnosed as primary endocardial fibroelastosis, two cases were misdiagnosed as coronary-pulmonary artery fistula; and one case was missed diagnosis). The working years of the physicians in the confirmed group were longer than those in the missed diagnosis/misdiagnosed group ((12.8±5.6) years vs. (8.3±4.7) years, P=0.045). In infants with ALCAPA, the detection rate of LCA-pulmonary shunt (8/10 vs. 0, P=0.035) and coronary collateral circulation (7/10 vs. 0, P=0.042) in confirmed group was higher than that in missed diagnosis/misdiagnosed group. In adult ALCAPA patients, the detection rate of LCA-pulmonary artery shunt was higher in confirmed group than that in missed diagnosis/misdiagnosed group (4/5 vs. 0, P=0.021). The missed diagnosis/misdiagnosis rate of adult type was higher than that of infant type (3/8 vs. 3/13, P=0.410). The rate of missed diagnosis/misdiagnosis was higher in patients with abnormal origin of branches than that of abnormal origin of main trunk (1/1 vs. 5/21, P=0.028). The rate of missed diagnosis/misdiagnosis in patients with LCA running between the main and pulmonary arteries was higher than that distant from the main pulmonary artery septum (4/7 vs. 2/14, P=0.064). The rate of missed diagnosis/misdiagnosis in patients with severe pulmonary hypertension was higher than that in patients without severe pulmonary hypertension (2/3 vs. 4/18, P=0.184). The reasons with an echocardiography missed diagnosis/misdiagnosis rate of≥50% included that (1) the proximal segment of LCA ran between the main and pulmonary arteries; (2) abnormal opening of LCA at the right posterior part of the pulmonary artery; (3) abnormal origin of LCA branches; (4) complicated with severe pulmonary hypertension. Conclusions: Echocardiography physicians' knowledge of ALCAPA and diagnostic vigilance are critical to the accuracy of diagnosis. Attention should be paid to the pediatric cases with no obvious precipitating factors of left ventricular enlargement, regardless of whether the left ventricular function is normal or not, the origin of coronary artery should be routinely explored.

Abstract
BACKGROUND RNA 5-methylcytosine (m5C) modification plays critical roles in the pathogenesis of various tumors. However, the function and molecular mechanism of RNA m5C modification in tumor drug resistance remain unclear. METHODS The correlation between RNA m5C methylation, m5C writer NOP2/Sun RNA methyltransferase family member 2 (NSUN2) and EGFR-TKIs resistance was determined in non-small-cell lung cancer (NSCLC) cell lines and patient samples. The effects of NSUN2 on EGFR-TKIs resistance were investigated by gain- and loss-of-function assays in vitro and in vivo. RNA-sequencing (RNA-seq), RNA bisulfite sequencing (RNA-BisSeq) and m5C methylated RNA immunoprecipitation-qPCR (MeRIP-qPCR) were performed to identify the target gene of NSUN2 involved in EGFR-TKIs resistance. Furthermore, the regulatory mechanism of NSUN2 modulating the target gene expression was investigated by functional rescue and puromycin incorporation assays. RESULTS RNA m5C hypermethylation and NSUN2 were significantly correlated with intrinsic resistance to EGFR-TKIs. Overexpression of NSUN2 resulted in gefitinib resistance and tumor recurrence, while genetic inhibition of NSUN2 led to tumor regression and overcame intrinsic resistance to gefitinib in vitro and in vivo. Integrated RNA-seq and m5C-BisSeq analyses identified quiescin sulfhydryl oxidase 1 (QSOX1) as a potential target of aberrant m5C modification. NSUN2 methylated QSOX1 coding sequence region, leading to enhanced QSOX1 translation through m5C reader Y-box binding protein 1 (YBX1). CONCLUSIONS Our study reveals a critical function of aberrant RNA m5C modification via the NSUN2-YBX1-QSOX1 axis in mediating intrinsic resistance to gefitinib in EGFR-mutant NSCLC.

Abstract
Objective: To investigate the effect of information management of intravenous drugs on anemia in maintenance hemodialysis patients. Methods: The information management of intravenous drugs was a management system developed by the Hemodialysis Center of Shanghai Jiao Tong University School of Medicine Affiliated Sixth People's Hospital in April 2020. The parameters six months before and after the use of the information management system were retrospectively collected and compared, including the rate of reaching the standard of hemoglobin, ferritin, transferrin saturation rate and the incidence of cardiovascular events. Specifically, the control stage was from October 2019 to March 2020, which was before the use of information management, and the study stage was from April to September 2020, which was after the use of information management. Results: There were 285 patients (190 males and 95 females) included in the control stage, with an average age of (62.4±13.2) years, while 278 patients (193 males and 85 females) were included in the study stage, with an average age of (62.8±13.2) years. Compared with the control stage, the rate of reaching the standard of hemoglobin [47.8% (797/1 668) vs 40.2% (687/1 710), P<0.001], ferritin [39.0% (217/556) vs 31.2% (178/570), P=0.006], and transferrin saturation [64.7% (360/556) vs 58.6% (334/570), P=0.034] increased in the study stage. The incidence of cardiovascular events in the study stage was 11.2% (31/278), which was significantly lower than that in the control stage [16.5% (47/285)] (P=0.043). Conclusion: The information management of intravenous drugs in the hemodialysis center may help improve the anemia status in maintenance hemodialysis patients.

Abstract
This study compares the effectiveness of pharmacological treatments to develop guidelines for the management of acute pain after tooth extraction. We searched Medline, EMBASE, CENTRAL, and US Clinical Trials registry on November 21, 2020. We included randomized clinical trials (RCTs) of participants undergoing dental extractions comparing 10 interventions, including acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and combinations to placebo. After duplicate screening and data abstraction, we conducted a frequentist network meta-analysis for each outcome at 6 h (i.e., pain relief, total pain relief [TOTPAR], summed pain intensity difference [SPID], global efficacy rating, rescue analgesia, and adverse effects). We assessed the risk of bias using a modified Cochrane RoB 2.0 tool and the certainty of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation approach. We implemented the analyses in RStudio version 3.5.3 and classified interventions from most to least beneficial or harmful. We included 82 RCTs. Fifty-six RCTs enrolling 9,095 participants found moderate- and high-certainty evidence that ibuprofen 200 to 400 mg plus acetaminophen 500 to 1,000 mg (mean difference compared to placebo [MDp], 1.68; 95% confidence interval [CI], 1.06-2.31), acetaminophen 650 mg plus oxycodone 10 mg (MDp, 1.19; 95% CI, 0.85-1.54), ibuprofen 400 mg (MDp, 1.31; 95% CI, 1.17-1.45), and naproxen 400-440 mg (MDp, 1.44; 95% CI, 1.07-1.80) were most effective for pain relief on a 0 to 4 scale. Oxycodone 5 mg, codeine 60 mg, and tramadol 37.5 mg plus acetaminophen 325 mg were no better than placebo. The results for TOTPAR, SPID, global efficacy rating, and rescue analgesia were similar. Based on low- and very low-certainty evidence, most interventions were classified as no more harmful than placebo for most adverse effects. Based on moderate- and high-certainty evidence, NSAIDs with or without acetaminophen result in better pain-related outcomes than opioids with or without acetaminophen (except acetaminophen 650 mg plus oxycodone 10 mg) or placebo.

Abstract
Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is a syndrome with high short-term mortality. The mechanism of the transcription factor ETS2 in ACLF remains unclear. This study aimed to clarify the molecular basis of ETS2 in ACLF pathogenesis. Peripheral blood mononuclear cells from patients with HBV-ACLF (n=50) were subjected to RNA sequencing. Transcriptome analysis showed that ETS2 expression was significantly higher in ACLF patients than in patients with chronic liver diseases and healthy subjects (all P<0.001). Area-under-ROC analysis of ETS2 demonstrated high values for the prediction of 28-/90-day mortality in ACLF patients (0.908/0.773). Significantly upregulated signatures of the innate immune response (monocytes/neutrophils/inflammation-related pathways) were observed in ACLF patients with high ETS2 expression. Myeloid-specific ETS2 deficiency in liver failure mice resulted in deterioration of biofunctions and increased expression of proinflammatory cytokines (IL-6/IL-1β/TNF-α). Knockout of ETS2 in macrophages confirmed the downregulation of IL-6 and IL-1β caused by both HMGB1 and lipopolysaccharide, and an NF-κB inhibitor reversed the suppressive effect of ETS2. ETS2 is a potential prognostic biomarker of ACLF patients that alleviates liver failure by downregulating the HMGB1-/lipopolysaccharide-triggered inflammatory response and may serve as a therapeutic target for ACLF.

Abstract
Metal ions widely exist in biological systems and participate in many vital biochemical processes. Monitoring and analyzing metal ions in biological systems can help reveal physiological processes and understand disease causes. There are various detection methods for metal ions, among which organic small-molecule fluorescent probes have significant advantages, such as high fluorescence quantum yield, easy modification, good biocompatibility, high sensitivity, and fast real-time detection. This review presents recent studies on fluorescent probes for alkali and alkaline earth metal ions (including Na+, K+, Ca2+, and Mg2+) in biological systems. All the candidates are organized according to their structures, and the sensing mechanisms of fluorescent probes are also highly taken into account. Finally, the challenges, trends and prospects of fluorescent probes in metal ion detection are discussed. We hope that this review can provide guidance for the development of fluorescent molecular probe-based alkali and alkaline earth metal ion detection methods in the future.

Abstract
Objective: To explore the clinical effects of free pre-expanded deltopectoral flap transfer in facial scar reconstruction by selecting appropriate internal thoracic artery perforator as the pedicle through preoperative color Doppler ultrasonic vascular assessment. Methods: A retrospective observational study was conducted. From September 2017 to March 2021, 11 patients with facial scar who met the inclusion criteria were admitted to the First Affiliated Hospital of Xi'an Jiaotong University, including 6 males and 5 females, aged 16-58 (31±12) years. The scar with area ranging from 7 cm×5 cm to 14 cm×9 cm was reconstructed by free pre-expanded internal thoracic artery perforator pedicled deltopectoral flap transfer. The operation was performed in 2 or 3 stages. Before operation, color Doppler ultrasonography was performed to evaluate the internal thoracic artery perforator. In the first stage, skin and soft tissue expander (hereinafter referred to as expander) implantation was performed, and a cylindrical expander with rated capacity of 400 to 600 mL was placed in the chest wall. The expansion time was 3 to 4 months, and the water injection volume reached 1.2-1.5 times of the rated capacity of expander. In the second stage, scar excision+free pre-expanded deltopectoral flap transfer was performed, with harvested flap area ranging from 9 cm×7 cm to 16 cm×10 cm. The vascular pedicle of flap (intercostal perforator of internal thoracic artery) was anastomosed end-to-end to the facial artery and vein or superficial temporal artery and vein. The wound in donor site was closed directly. Third stage operation thinning was performed at 3-6 months after the second stage operation in 5 patients because of bloated flap pedicle. At 6 months after the last operation, the flap survival and complications were recorded, the sensation of flap was evaluated by Semmes-Weinstein monofilament test, the color of flap was evaluated by color contrast of the flap to surrounding normal skin, and the curative effect satisfaction degree of patients was evaluated by 5-grade Likert scale. Results: At 6 months after the last operation, all the flaps of 11 patients survived well. One patient experienced venous congestion after flap transplantation, but the flap survived after re-anastomosis. One patient experienced hematoma after the first stage operation of expander implantation, but the rest treatment was not influenced after hematoma removal. No complications such as infection or expander exposure occurred in any patient. At 6 months after the last operation, the sensation of flap of patient was as follows: 9 cases recovered to protective sensation decrease or better, 1 case had protective sensation defect, and 1 case only had deep touch and pressure sensation; the color of flap of patient was as follows: 3 cases were very close to the color of surrounding normal skin, 6 cases were close to the color of surrounding normal skin, and 2 cases were different to the color of surrounding normal skin; the curative effect satisfaction degree of patients was as follows: 2 patients were very satisfied, 6 patients were satisfied, 2 patients were somewhat satisfied, and 1 patient was a little not satisfied. Conclusions: The large area facial scar can be treated safely and effectively by free pre-expanded deltopectoral flap with appropriate single internal thoracic artery perforator as vascular pedicle selected through vascular assessment by color Doppler ultrasonography before operation. After operation, the color of flap of patients is close to the surrounding normal skin and the sensation of flap can be partially recovered, with high curative effect satisfaction degree of patients.

Abstract
Functional bioengineered livers (FBLs) are promising alternatives to orthotopic liver transplantation. However, orthotopic transplantation of FBLs has not yet been reported. This study aimed to perform the orthotopic transplantation of FBLs in rats subjected to complete hepatectomy. FBLs were developed using rat whole decellularized liver scaffolds (DLSs) with human umbilical vein endothelial cells implanted via the portal vein, and human bone marrow mesenchymal stem cells (hBMSCs) and mouse hepatocyte cell line implanted via the bile duct. FBLs were evaluated in terms of endothelial barrier function, biosynthesis, and metabolism and orthotopically transplanted into rats to determine the survival benefit. The FBLs with well-organized vascular structures exhibited endothelial barrier function, with reduced blood cell leakage. The implanted hBMSCs and hepatocyte cell line were well aligned in the parenchyma of the FBLs. The high levels of urea, albumin, and glycogen in the FBLs indicated biosynthesis and metabolism. Orthotopic transplantation of FBLs achieved a survival time of 81.38 ± 4.263 min in rats (n = 8) subjected to complete hepatectomy, whereas control animals (n = 4) died within 30 min (p < 0.001). After transplantation, CD90-positive hBMSCs and the albumin-positive hepatocyte cell line were scattered throughout the parenchyma, and blood cells were limited within the vascular lumen of the FBLs. In contrast, the parenchyma and vessels were filled with blood cells in the control grafts. Thus, orthotopic transplantation of whole DLS-based FBLs can effectively prolong the survival of rats subjected to complete hepatectomy. In summary, this work was the first to perform the orthotopic transplantation of FBLs, with limited survival benefits, which still has important value for the advancement of bioengineered livers.

Abstract
As China’s natural resource governance has turned to high-quality management, establishing reasonable and ecological land-use patterns is an effective means of promoting natural resource utilization and improving the quality of the ecological environment. Therefore, this study used ecological land as the expansion source to construct an ecological land-use pattern with the minimum cumulative resistance model in Haixing County, China, based on regional food security, ecological security, and construction land expansion patterns. This work also involved designing ecological corridors, radiation channels, strategic nodes, and other ecological components. The results demonstrate that (1) the ecological land source is 7976.93 hm2, accounting for 9.19% of the total area. It is mainly distributed in the southeast of the county, mainly in the river system and woodland; (2) the food security situation of Haixing County can be divided into four zones, most of which are agricultural adjustment areas, indicating that the ecological security of cultivated land in this area needs to be improved; (3) the ecological security level of Haixing County is divided into four areas, and the ideal safety zone accounts for the smallest area, indicating that the regional ecological situation is very unstable; (4) construction land expansion zone is divided into four parts. A suitable construction zone occupies the largest area and is mainly distributed around the current construction land; (5) the expansion of the ecological land-use pattern of Haixing County includes four zones, 15 ecological corridors, 12 radiation channels, and 35 strategic nodes, which is conducive to optimal land allocation from an ecological security perspective. This paper puts forward some suggestions for ecological protection and intensive urban development.

Abstract
BACKGROUND AND AIMS Human bone marrow mesenchymal stem cells (hBMSCs) are important for developing a dual-humanized mouse model to clarify disease pathogenesis. We aimed to elucidate the characteristics of hBMSC transdifferentiation into liver and immune cells. METHODS A single type of hBMSCs was transplanted into immunodeficient Fah-/- Rag2-/- IL-2Rγc-/- SCID (FRGS) mice with fulminant hepatic failure (FHF). Liver transcriptional data from the hBMSC-transplanted mice were analysed to identify transdifferentiation with traces of liver and immune chimerism. RESULTS Mice with FHF were rescued by implanted hBMSCs. Human albumin/leukocyte antigen (HLA) and CD45/HLA double-positive hepatocytes and immune cells were observed in the rescued mice during the initial 3 days. The transcriptomics analysis of liver tissues from dual-humanized mice identified two transdifferentiation phases (cellular proliferation at 1-5 days and cellular differentiation/maturation at 5-14 days) and ten cell lineages transdifferentiated from hBMSCs: human hepatocytes, cholangiocytes, stellate cells, myofibroblasts, endothelial cells and immune cells (T/B/NK/NKT/Kupffer cells). Two biological processes, hepatic metabolism and liver regeneration, were characterized in the first phase, and two additional biological processes, immune cell growth and extracellular matrix (ECM) regulation, were observed in the second phase. Immunohistochemistry verified that the ten hBMSC-derived liver and immune cells were present in the livers of dual-humanized mice. CONCLUSIONS A syngeneic liver-immune dual-humanized mouse model was developed by transplanting a single type of hBMSC. Four biological processes linked to the transdifferentiation and biological functions of ten human liver and immune cell lineages were identified, which may help to elucidate the molecular basis of this dual-humanized mouse model for further clarifying disease pathogenesis.

Abstract
Objective: To explore the family rehabilitation model for children with scar contracture after hand burns and observe its efficacy. Methods: A retrospective non-randomized controlled study was conducted. From March 2020 to March 2021, 30 children with scar contracture after deep partial-thickness to full-thickness burns of hands, who met the inclusion criteria, were hospitalized in the Burn Center of PLA of the First Affiliated Hospital of Air Force Medical University. According to the rehabilitation model adopted, 18 children (23 affected hands) were included in a group mainly treated by family rehabilitation (hereinafter referred to as family rehabilitation group), and 12 children (15 affected hands) were included in another group mainly treated by hospital rehabilitation (hereinafter referred to as hospital rehabilitation group). In the former group, there were 11 males and 7 females, aged (4.8±2.1) years, who began rehabilitation treatment (3.1±0.8) d after wound healing; in the latter group, there were 7 males and 5 females, aged (4.6±2.1) years, who began rehabilitation treatment (2.8±0.7) d after wound healing. The children in hospital rehabilitation group mainly received active and passive rehabilitation training in the hospital, supplemented by independent rehabilitation training after returning home; after 1-2 weeks of active and passive rehabilitation training in the hospital, the children in family rehabilitation group received active and passive rehabilitation training at home under the guidance of rehabilitation therapists through WeChat platform. Both groups of children were treated for 6 months. During the treatment, they wore pressure gloves and used hand flexion training belts and finger splitting braces. Before treatment and after 6 months of treatment, the modified Vancouver scar scale, the total active movement of the hand method, and Carroll quantitative test of upper extremity function were used to score/rate the scar of the affected hand (with the difference of scar score between before treatment and after treatment being calculated), the joint range of motion (with excellent and good ratio being calculated), and the function of the affected limb, respectively. Data were statistically analyzed with independent sample t test, equivalence test, Fisher's exact probability test, and Mann-Whitney U test. Results: The differences of scar scores of the affected hands of children in family rehabilitation group and hospital rehabilitation group between after 6 months of treatment and those before treatment were 3.0 (2.0, 7.0) and 3.0 (2.0, 8.0) respectively (with 95% confidence interval of 2.37-5.38 and 1.95-5.91). The 95% confidence interval of the difference between the differences of the two groups was -2.43-2.21, which was within the equivalent boundary value of -3-3 (P<0.05). The excellent and good ratios of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group were 3/23 and 2/15 respectively before treatment, and 15/23 and 12/15 respectively after 6 months of treatment. The ratings of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.58 and 2.30, respectively, P<0.05), but the ratings of joint range of motion of the affected hand between the two groups were similar before treatment and after 6 months of treatment (with Z values of 0.39 and 0.55, respectively, P>0.05). The functional ratings of the affected limbs of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.98 and 3.51, respectively, P<0.05), but the functional ratings of the affected limbs between the two groups were similar before treatment and after 6 months of treatment (with Z values of 1.27 and 0.38, respectively, P>0.05). Conclusions: The WeChat platform assisted rehabilitation treatment with mainly family rehabilitation, combined with hand flexion and extension brace can effectively reduce the scarring after children's hand burns, improve the joint range of motion of the affected hands, and promote the recovery of affected limb function. The effect is similar to that of hospital-based rehabilitation providing an optional rehabilitation, treatment method for children who cannot continue to receive treatment in hospital.

Abstract
In the salivary glands, fibrosis occurs in many pathological conditions. Endothelial tight junction (TJ)-based barrier function plays a vital role in maintaining the homeostasis of the salivary glands. However, whether endothelial barrier function is changed and involved in the pathogenesis of glandular fibrosis is unknown. Here, by using a mouse model in which the main excretory duct of the submandibular gland (SMG) was ligated to induce inflammation and fibrosis, endothelial barrier function and TJ protein expression and distribution were examined. Both 4-kDa and 70-kDa fluorescence-labeled dextrans permeated more in the 1-, 3-, and 7-d ligated SMGs. Meanwhile, the mRNA level of claudin-5 was increased with an obvious redistribution from apicolateral membranes to lateral membranes and cytoplasm in the fibrotic glands. Notably, the TJ sealer AT1001 significantly attenuated the disrupted endothelial barrier function and thereby ameliorated the glandular fibrosis. Cytokine array detection showed that monocyte chemoattractant protein-1 (MCP-1) was highly enriched in the 3-d ligated SMGs, and MCP-1 directly impaired barrier function, increased claudin-5 expression, induced the relocalization of claudin-5, and activated p-ERK1/2 in cultured human endothelial cells. Furthermore, the upregulation and disorganization of claudin-5 as well as the elevation of MCP-1 and p-ERK1/2 signaling were also confirmed in fibrotic SMGs from patients with chronic sialadenitis and immunoglobulin G4-related sialadenitis. Altogether, our findings revealed that disrupted endothelial barrier function contributed to the progression of glandular fibrosis, and targeting endothelial TJs might be a promising approach to alleviate salivary gland fibrosis-related diseases.
