Abstract
OBJECTIVES The current work aimed to provide a comprehensive single-cell landscape of lupus nephritis (LN) kidneys, including immune and non-immune cells, identify disease-associated cell populations and unravel their participation within the kidney microenvironment. METHODS Single-cell RNA and T cell receptor sequencing were performed on renal biopsy tissues from 40 patients with LN and 6 healthy donors as controls. Matched peripheral blood samples from seven LN patients were also sequenced. Multiplex immunohistochemical analysis was performed on an independent cohort of 60 patients and validated using flow cytometric characterisation of human kidney tissues and in vitro assays. RESULTS We uncovered a notable enrichment of CD163+ dendritic cells (DC3s) in LN kidneys, which exhibited a positive correlation with the severity of LN. In contrast to their counterparts in blood, DC3s in LN kidney displayed activated and highly proinflammatory phenotype. DC3s showed strong interactions with CD4+ T cells, contributing to intrarenal T cell clonal expansion, activation of CD4+ effector T cell and polarisation towards Th1/Th17. Injured proximal tubular epithelial cells (iPTECs) may orchestrate DC3 activation, adhesion and recruitment within the LN kidneys. In cultures, blood DC3s treated with iPTECs acquired distinct capabilities to polarise Th1/Th17 cells. Remarkably, the enumeration of kidney DC3s might be a potential biomarker for induction treatment response in LN patients. CONCLUSION The intricate interplay involving DC3s, T cells and tubular epithelial cells within kidneys may substantially contribute to LN pathogenesis. The enumeration of renal DC3 holds potential as a valuable stratification feature for guiding LN patient treatment decisions in clinical practice.

Abstract
Objective: To investigated the safety and efficacy of donor-derived CD19+ or sequential CD19+ CD22+ chimeric antigen receptor T-cell (CAR-T) therapy in patients with B-cell acute lymphoblastic leukemia (B-ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: The data of 22 patients with B-ALL who relapsed after allo-HSCT and who underwent donor-derived CAR-T therapy at the Zhujiang Hospital of Southern Medical University and the 920th Hospital of Joint Logistics Support Force of the People's Liberation Army of China from September 2015 to December 2022 were retrospectively analyzed. The primary endpoint was overall survival (OS), and the secondary endpoints were event-free survival (EFS), complete remission (CR) rate, and Grade 3-4 adverse events. Results: A total of 81.82% (n=18) of the 22 patients achieved minimal residual disease-negative CR after CAR-T infusion. The median follow-up time was 1037 (95% CI 546-1509) days, and the median OS and EFS were 287 (95% CI 132-441) days and 212 (95% CI 120-303) days, respectively. The 6-month OS and EFS rates were 67.90% (95% CI 48.30%-84.50%) and 58.70% (95% CI 37.92%-79.48%), respectively, and the 1-year OS and EFS rates were 41.10% (95% CI 19.15%-63.05%) and 34.30% (95% CI 13.92%-54.68%), respectively. Grade 1-2 cytokine release syndrome occurred in 36.36% (n=8) of the patients, and grade 3-4 occurred in 13.64% of the patients (n=3). Grade 2 and 4 graft-versus-host disease occurred in two patients. Conclusion: Donor-derived CAR-T therapy is safe and effective in patients with relapsed B-ALL after allo-HSCT.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Extracellular elastase-like protease is one of the key virulence proteases of Scedosporium aurantiacum. To date, little is known about this enzyme in terms of genetic information, structure, properties and virulence mechanism due to the difficulties in purification caused by its low secretion amount, high specific activity, uncompleted genome sequencing and annotation. This work investigated the gene, structure and enzymatic properties of this enzyme. The S. aurantiacum elastase-like protease from the fungal culture supernatant was analyzed through tandem mass spectrometry (MS/MS) approach, illustrating its primary structure. Bioinformatics tools were employed to predict the conserved domain and tertiary structure, the enzymatic properties were also studied. It turned out that S. aurantiacum extracellular elastase-like protease demonstrated well hydrolysis towards elastin and bovine achilles tendon collagen, with Vmax of 18.14 μg/s and 17.57 μg/s respectively, better than fish scale gelatin, with the lowest hydrolysis effect on casein. Its activity towards elastin was lower than that of the elastase from porcine pancreas, with values of Kcat/Km of 3.541 (μg/s) and 4.091 (μg/s), respectively. It was an alkaline protease, with optimal pH 8.2 and temperature 37 oC. Zn2+ promoted the enzymatic activity while Ca2+, Mg2+, Na+, elastatinal and PMSF inhibited its activity. Its sequence was similar to Paecilomyces lilacinus secreted serine protease (PDB Entry: c3f7oB_) with multiple conserved fractions each containing more than 7 amino acids, thus suitable for design of PCR primer. This study increased our knowledge on S. aurantiacum extracellular elastase-like protease in terms of structure and enzymatic properties, and may facilitate later studies on protein expression and virulence mechanism.

Abstract
AIMS To evaluate the potential applications of soy protein-glucan-catechin (SGC) complexes prepared with different ultrasound times in stabilising high internal phase Pickering emulsion (HIPPE) and delivering curcumin. METHODS The SGC complexes were characterised by particle size, morphology, zeta potential, Fourier transform infra-red, and fluorescence spectroscopy. Formation and stability of curcumin emulsions were monitored by droplet size, microstructure, rheological property, lipid oxidation, and in vitro digestion. RESULTS Short-time ultrasound-induced complexes (SGC-U15) exhibited a small size and wettability of ∼82.5°. The chemical stability and bioaccessibility of curcumin was greatly improved by SGC-U15-stabilised HIPPEs, even after 70 days of storage, heating at 100 °C for 30 min, ultraviolet irradiation for 120 min, and in vitro digestion, owing to the formation of elastic gel-like structure at the oil/water interfaces. CONCLUSION Our findings may contribute to the design of emulsion-based delivery systems using ultrasound-induced protein-polysaccharide-polyphenol complexes.

Abstract
In this study, zein-soy isoflavone complex (ZSI) emulsifiers were fabricated using ultrasound-assisted dynamic high-pressure micro fluidization to stabilise highinternal phase pickering emulsions. Ultrasound-assisted dynamic high-pressure micro-fluidization enhanced surface hydrophobicity, zeta potential, and soy isoflavone binding capacity, while it decreased particle size, especially during ultrasound and subsequent microfluidization. The treated ZSI could produce small droplet clusters and gel-like structures, with excellent viscoelasticity, thixotropy and creaming stability owing to their neutral contact angles. Ultrasound and subsequent micro fluidization treatment of the ZSI complexes were highly effective in preventing droplet flocculation and coalescence after long-term storage or centrifugation due to their higher surface load, thicker multi-layer interfacial structure, and stronger electronic repulsion between the oil droplets. This study provides insights and extends our current knowledge of how non-thermal technology affects the interfacial distribution of plant based particles and the physical stability of emulsions.

Abstract
Hepatic metastasis develops in ∼50% of uveal melanoma (UM) patients with scarcely effective treatment resulting in lethality. The underlying mechanism of liver metastasis remains elusive. Ferroptosis, a cell death form characterized by lipid peroxide, in cancer cells may decrease metastatic colonization. In the present study, we hypothesized that decapping scavenger enzymes (DCPS) impact ferroptosis by regulating mRNA decay during the metastatic colonization of UM cells to liver. We found that inhibition of DCPS by shRNA or RG3039 induced gene transcript alteration and ferroptosis through reducing the mRNA turnover of GLRX. Ferroptosis induced by DCPS inhibition eliminates cancer stem-like cells in UM. Inhibition of DCPS hampered the growth and proliferation both in vitro and in vivo. Furthermore, targeting DCPS diminished hepatic metastasis of UM cells. These findings may shed light on the understanding of DCPS-mediated pre-mRNA metabolic pathway in UM by which disseminated cells gain enhanced malignant features to promote hepatic metastasis, providing a rational target for metastatic colonization in UM.

Abstract
The five recognized zoonotic foodborne pathogens, namely, Listeria monocytogenes, Staphylococcus aureus, Streptococcus suis, Salmonella enterica and Escherichia coli O157:H7, pose a major threat to global health and social-economic development. These pathogenic bacteria can cause human and animal diseases through foodborne transmission and environmental contamination. Rapid and sensitive detection for pathogens is particularly important for the effective prevention of zoonotic infections. In this study, rapid and visual europium nanoparticle (EuNP)-based lateral flow strip biosensors (LFSBs) combined with recombinase polymerase amplification (RPA) were developed for the simultaneous quantitative detection of five foodborne pathogenic bacteria. Multiple T lines were designed in a single test strip for increasing the detection throughput. After optimizing the key parameters, the single-tube amplified reaction was completed within 15 min at 37 °C. The fluorescent strip reader recorded the intensity signals from the lateral flow strip and converted the data into a T/C value for quantification measurement. The sensitivity of the quintuple RPA-EuNP-LFSBs reached a level of 101 CFU/mL. It also exhibited good specificity and there was no cross-reaction with 20 non-target pathogens. In artificial contamination experiments, the recovery rate of the quintuple RPA-EuNP-LFSBs was 90.6-101.6%, and the results were consistent with those of the culture method. In summary, the ultrasensitive bacterial LFSBs described in this study have the potential for widespread application in resource-poor areas. The study also provides insights in respect to multiple detection in the field.

Abstract
Recent progress in microspherical superlens nanoscopy raises a fundamental question about the transition from super-resolution properties of mesoscale microspheres, which can provide a subwavelength resolution [Formula: see text], to macroscale ball lenses, for which the imaging quality degrades because of aberrations. To address this question, this work develops a theory describing the imaging by contact ball lenses with diameters [Formula: see text] covering this transition range and for a broad range of refractive indices [Formula: see text]. Starting from geometrical optics we subsequently proceed to an exact numerical solution of the Maxwell equations explaining virtual and real image formation as well as magnification M and resolution near the critical index [Formula: see text] which is of interest for applications demanding the highest M such as cellphone microscopy. The wave effects manifest themselves in a strong dependence of the image plane position and magnification on [Formula: see text], for which a simple analytical formula is derived. It is demonstrated that a subwavelength resolution is achievable at [Formula: see text]. The theory explains the results of experimental contact-ball imaging. The understanding of the physical mechanisms of image formation revealed in this study creates a basis for developing applications of contact ball lenses in cellphone-based microscopy.

Abstract
BACKGROUND Positive antineutrophil cytoplasmic antibody (ANCA) serology in adult-onset lupus nephritis (LN) is associated with more active disease and distinct renal pathology, but data with respect to childhood-onset LN remain scarce. Here, we aimed to determine the impact of positive ANCA serology on clinical and histopathologic features and renal outcomes in children with LN from multiple centers. METHODS Clinical and histopathologic data of 61 ANCA-positive and 330 ANCA-negative LN children (1<age≤18 years) retrospectively enrolled from three pediatric nephrology centers were analyzed. Among them, 217 children were followed and survival analysis was performed. RESULTS Among 61 ANCA-positive LN children, 86.9% of them had antimyeloperoxidase antibodies. Both ANCA-positive and ANCA-negative children had high disease activities with median SLEDAI-2K of 16 (13, 20). Hematuria was more prominent (urinary RBC +++ ∼ ++++: 45.9% vs 26.7%, p = 0.011), while fever (42.6% vs. 58.2%, p = 0.035), alopecia (3.3% vs. 14.5%, p = 0.019), photosensitivity (0% vs. 8.2%, p = 0.013), and pleurisy (4.9% vs. 15.8%, p = 0.026) were less common in ANCA-positive children. Higher proportions of segmental sclerosis (23.7% vs. 9.8%, p = 0.025), crescentic formation (36.4% vs. 16.3%, p = 0.009), and capillary wall thickening (24.5% vs. 11.0%, p = 0.01) were observed in biopsies of ANCA-positive children. Long-term renal survival did not differ significantly between two groups (p = 0.300). CONCLUSIONS Positive ANCA serology in LN children was associated with different clinical and histopathologic features compared to those with negative ANCA serology. Further studies are needed to clarify the pathogenic role of ANCAs in childhood-onset LN and confirm their association with prognosis.

Abstract
In this paper, a CNN-MLP model (CMM) is proposed for COVID-19 lesion segmentation and severity grading in CT images. The CMM starts by lung segmentation using UNet, and then segmenting the lesion from the lung region using a multi-scale deep supervised UNet (MDS-UNet), finally implementing the severity grading by a multi-layer preceptor (MLP). In MDS-UNet, shape prior information is fused with the input CT image to reduce the searching space of the potential segmentation outputs. The multi-scale input compensates for the loss of edge contour information in convolution operations. In order to enhance the learning of multiscale features, the multi-scale deep supervision extracts supervision signals from different upsampling points on the network. In addition, it is empirical that the lesion which has a whiter and denser appearance tends to be more severe in the COVID-19 CT image. So, the weighted mean gray-scale value (WMG) is proposed to depict this appearance, and together with the lung and lesion area to serve as input features for the severity grading in MLP. To improve the precision of lesion segmentation, a label refinement method based on the Frangi vessel filter is also proposed. Comparative experiments on COVID-19 public datasets show that our proposed CMM achieves high accuracy on COVID-19 lesion segmentation and severity grading. Source codes and datasets are available at our GitHub repository (https://github.com/RobotvisionLab/COVID-19-severity-grading.git).

Abstract
OBJECTIVE The aim of this study was to investigate serum levels of soluble B-cell maturation antigen (sBCMA) in childhood-onset systemic lupus erythematous (cSLE) patients with renal involvement, and to elucidate their association with clinical characteristics. METHODS 116 cases of cSLE patients with renal involvement (84 females and 32 males; median age 11.6 (10.1, 12.9) years) hospitalized in Department of Pediatric Nephrology and Rheumatology, the First Affiliated Hospital, Sun Yat-sen University and 31 healthy controls (HCs) were enrolled. Serum concentrations of sBCMA were determined using enzyme-linked immunosorbent assay (ELISA). Clinical and laboratory information of cSLE patients were retrospectively analyzed. RESULTS Serum sBCMA levels were significantly increased in primary cSLE when compared with treated cSLE patients and HCs, whereas there was no significant difference between treated cSLE patients and HCs. Patients with high disease activity displayed higher serum sBCMA levels compared with those with no or mild to moderate disease activity. Positive correlation was observed between serum sBCMA levels and systemic lupus erythematosus disease activity index-2K (SLEDAI-2K), antinuclear antibody titers, anti-double-stranded DNA titers, erythrocyte sedimentation rate, and immunoglobulin G levels, while sBCMA levels were negatively correlated with blood white blood cell count, hemoglobin, platelet count, complement C3 and C4 levels. Serum sBCMA levels decreased as disease ameliorated after treatments among 11 cases with follow-up examinations. CONCLUSIONS In cSLE patients with renal involvement, serum sBCMA levels correlated significantly with disease activity, immunological, and hematological parameters, but not with renal parameters. Our results suggest the potential and significance of serum sBCMA as a biomarker in cSLE patients.

Abstract
Objective: To explore the related factors of negative conversion time (NCT) of nucleic acid in children with COVID-19. Methods: A retrospective cohort study was conducted. A total of 225 children who were diagnosed with COVID-19 and admitted to Changxing Branch of Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 3rd to May 31st 2022 were enrolled in the study. The infection age, gender, viral load, basic disease, clinical symptoms and information of accompanying caregivers were retrospectively analyzed. According to age, the children were divided into<3 years of age group and 3-<18 years of age group. According to the viral nucleic acid test results, the children were divided into positive accompanying caregiver group and negative accompanying caregiver group. Comparisons between groups were performed using Mann-Whitney U test or Chi-square test. Multivariate Logistic regression analysis was used to analyze the related factors of NCT of nucleic acid in children with COVID-19. Results: Among the 225 patients (120 boys and 105 girls) of age 2.8 (1.3, 6.2) years, 119 children <3 years and 106 children 3-<18 years of age, 19 cases were diagnosed with moderate COVID-19, and the other 206 cases were diagnosed with mild COVID-19. There were 141 patients in the positive accompanying caregiver group and 84 patients in the negative accompanying caregiver group.Patients 3-<18 years of age had a shorter NCT (5 (3, 7) vs.7 (4, 9) d, Z=-4.17, P<0.001) compared with patients <3 years of age. Patients in the negative accompanying caregiver group had a shorter NCT (5 (3, 7) vs.6 (4, 9) d,Z=-2.89,P=0.004) compared with patients in the positive accompanying caregiver group. Multivariate Logistic regression analysis showed that anorexia was associated with NCT of nucleic acid (OR=3.74,95%CI 1.69-8.31, P=0.001). Conclusion: Accompanying caregiver with positive nucleic acid test may prolong NCT of nucleic acid, and decreased appetite may be associated with prolonged NCT of nucleic acid in children with COVID-19.

Abstract
Objective: To explore the etiological diagnostic value of metagenomic next-generation sequencing (mNGS) in peritoneal dialysis (PD)-related peritonitis. Methods: The study was a retrospective cohort study. The clinical data of patients with PD-related peritonitis who were treated and underwent microbial cultivation and mNGS test at the same time from June 2020 to July 2021 in the Affiliated Drum Tower Hospital, Medical School of Nanjing University were analyzed. The positive rate, detection time and consistency between mNGS test and traditional microbial culture were compared. Results: A total of 18 patients with age of (50.4±15.4) years old and median dialysis time of 34.0 (12.4, 62.0) months were enrolled in the study, including 11 males and 7 females. Pathogenic microorganisms were isolated in 17 patients by mNGS test, with a positive rate of 17/18, which was higher than 13/18 of microbial culture, but the difference was not statistically significant (P=0.219). Both mNGS test and microbial culture isolated positive pathogenic bacteria in 12 patients, and mNGS test isolated the same types of pathogenic bacteria as microbial cultivation did in 11 patients. In five patients with negative microbial culture, mNGS test also isolated pathogenic microorganisms, including 3 cases of Staphylococcus epidermidis, 1 case of Mycobacterium tuberculosis and 1 case of Ureaplasma urealyticum. In 1 patient, microbial culture isolated pathogenic bacteria (Escherichia coli) whereas mNGS test did not. The detection time of mNGS was 25.0 (24.0, 27.0) h, which was significantly shorter than 89.0 (72.8, 122.0) h of microbial culture (Z=3.726, P<0.001). Conclusions: mNGS test can improve the detection rate of pathogenic microorganisms in PD-related peritonitis and greatly shorten the detection time, and has good consistency with microbial culture. mNGS may provide a new approach for pathogen identification of PD-related peritonitis, especially refractory peritonitis.

Abstract
Research shows that the consumption of soybean foods can reduce the incidence rate of bone fractures in women after menopause. The aim of this study was to investigate the effects of different complex of soy β-conglycinin (7S) and isoflavones (7S-ISO) on osteoporosis in ovariectomized rats. All treatments were administrated intragastrically to the groups every afternoon for 3 months. The treatments were administrated at 1 mL·(100 g)-1 , the animals were given 50 mg·kg-1 ·d-1 ISO, and the concentration of protein was about 2 wt. %. The bone mineral density (BMD) and the bone biomechanics results of left tibia' maximum load in the 7S-ISO group is significantly higher than in the ovariectomized group and the 7S group (p < .05). Otherwise, the serum tartrate-resistant acid phosphatase (s-TRACP), serum osteocalcin (s-BGP), and serum estradiol (s-E2 ) levels in 7S-ISO were all significantly different from the OVX, OVX + casein, and the OVX + 7S group (p < .05). The serum calcium (s-Ca) level was not significantly different among all the groups. 7S-ISO may exhibit moderate estrogenic activities and as compared to 7S and ISO in osteoporosis (OP) of ovariectomized rats. PRACTICAL APPLICATIONS: The effects of soy proteins on the health of females have always been a concern. It has been extensively reported soy 7S globulin (7S) as a type of trimer glycoprotein can depress blood fats. The aim of this study was to investigate the effects of different complex of soy β-conglycinin and isoflavones (ISO), the main storage proteins and polyphenols in soy, on osteoporosis in ovariectomized rats.

Abstract
BACKGROUND Our previous study discovers that Jun N-terminal kinase pathway-associated phosphatase (JKAP) is dysregulated and negatively links with the disease severity in acute ischemic stroke (AIS) patients. This study intended to further evaluate the linkage of JKAP and interleukin (IL)-17A with anxiety, depression, and cognitive impairment in AIS patients. METHODS Serum JKAP and IL-17A levels in 120 AIS patients at admission, 1st (D1), 3rd (D3), 7th (D7) day after admission, and from 20 controls, were detected by ELISA. Hospital Anxiety and Depression Scale (HADS) and Mini-Mental State Examination (MMSE) were assessed in AIS patients at discharge. RESULTS JKAP (p < 0.001) was reduced, but IL-17A (p < 0.001) was increased in AIS patients versus controls, and negatively correlated with each other in AIS patients (p = 0.014). In AIS patients, JKAP was reduced from baseline to D1 and then increased to D7 (p < 0.001), while IL-17A exhibited an opposite trend (p < 0.001). Notably, JKAP at D3 was negatively linked with HADS-anxiety score (p = 0.044), then decreased JKAP at D3 (p = 0.017) and D7 (p = 0.037) related to increased anxiety occurrence. However, JKAP was not linked to HADS-depression score or depression occurrence. Besides, JKAP at multiple time points were positively associated with MMSE score (all p < 0.05); decreased JKAP at D3 (p = 0.017) and D7 (p = 0.026) related to raised cognitive impairment occurrence. CONCLUSION JKAP initially decreases then shows an increasing trend after disease onset, and its decrement relates to elevated IL-17A, anxiety and cognitive impairment in AIS patients.

Abstract
PURPOSE Oral squamous cell carcinoma (OSCC) local recurrence and distant metastasis remain a poorly understood clinical challenge. The objective of this study was to investigate how dysregulation of miR-382-5p impacts invasion and dissemination of OSCC. METHODS Tissue samples were collected from 20 subjects with OSCC. Expression levels of miR-382-5p were determined by quantitative real-time polymerase chain reaction (qRT-PCR), and correlations with clinical characteristics were investigated. qRT-PCR was used to determine the miR-382-5p and peptidyl-prolyl cis/trans isomerase (PTEN) expression in tumor tissues, adjacent normal tissues, normal human oral keratinocyte line, and OSCC line (SCC-9). Cell proliferation, invasion, and migration of knock-in and knock-down miR-382-5p transfectants were assessed using cell counting kit-8 and Transwell assays. PTEN was confirmed to be a downstream target using a TargetScan prediction, dual-luciferase reporter assays, and western blot analysis. Statistical analysis of experimental data was performed with SPSS 22.0 software. RESULTS We found high expression of miR-382-5p and significant downregulation of PTEN in tumor tissues and SCC-9 cells from OSCC patients (P < .05). miR-382-5p expression was lower in early stage (I + II) than in late stage (III + IV), while PTEN exhibited higher expression in early stage (I + II) instead of in late stage (III + IV) (P < .05). In addition, overexpression of miR-382-5p promoted the proliferation, invasion, and migration of OSCC cells. However, the proliferation, invasion, and migration of OSCC cells were inhibited after suppression of miR-382-5p. Finally, PTEN is downregulated by miR-382-5p. CONCLUSION MiR-382-5p supports proliferation, invasion, and migration of OSCC cells through the PTEN pathway. Further investigation may improve our understanding of OSCC local recurrence and distant metastasis.

Abstract
Objective: To investigate the changes of brain network characteristics in patients with depression before and after precise repetitive transcranial magnetic stimulation (rTMS) treatment. Methods: Patients with depression in the Second Affiliated Hospital of Xinxiang Medical University and healthy volunteers in the community of Xinxiang city from February 2018 to March 2019 were simultaneously recruited. The left dorsolateral prefrontal cortex was precisely selected as the stimulation target through the latest Human Brainnetome Atlas, and the near infrared navigation was used to achieve accurate brain stimulation treatment in combination with the structural magnetic resonance data. Moreover, functional connectivity was analyzed before and after rTMS treatment in significantly altered brain areas of patients with depression. Results: Nineteen patients (11 males and 8 females) with depression were included, aged (34±11) years. Meanwhile, 22 healthy controls (9 males and 13 females), aged (30±9) years, were also enrolled. Functional connectivity of insular cortex was decreased in depression patients when the insula was analyzed as the target area (P<0.05). The functional connection from insula to middle frontal lobe and superior parietal lobe in patients with depression decreased before rTMS treatment (P<0.05), but increased after rTMS treatment (P<0.05). The functional connection between dIg_L of the insula and the right middle prefrontal lobe was correlated with Beck Anxiety Index (BAI) before rTMS treatment and Beck Depression Index (BDI) after rTMS treatment (r=0.737, P=0.003; r=0.696, P=0.005). Conclusions: Abnormal functional connectivity of insula may be the brain imaging mechanism of rTMS treatment. Precise brain region selection based on Human Brainnetome Atlas provides a new technical method for clinical rTMS precision treatment.

Abstract
Abstract
Introduction/Objective
Hyperproliferation of epidermis is a histopathological hallmark of skin cancers and psoriasis. As a master regulator of centriole replication, overexpression of Polo-like kinase 4 (PLK4) has been identified in skin cancers. The aberrant proliferation of epidermal keratinocytes provoked by interleukin 17 (IL17) leads to psoriasis. Thus, targeting centriole replication and IL17 signaling simultaneously has been speculated as a potential therapeutic strategy. We hypothesized that inhibition of centriole duplication enhances the blockade of epidermal proliferation through Il17rc knockout.
Methods/Case Report
To test our hypothesis, 37 mice were used to imbed a two-stage model of skin carcinogenesis using wild-type (WT), IL17 receptor A (T779A) knock-in (Il17ra(T779A)-KI), and IL17 receptor C knock-out (Il17rc-KO) C57BL/6J mouse strains. Furthermore, an imiquimod-induced psoriasis model was established using 69 mice with the same strains.
Results (if a Case Study enter NA)
In our two-stage skin carcinogenesis model, Il17ra(T779A)-KI mice showed significantly decreased tumor incidence, tumor multiplicity, and tumor volume compared to the WT mice. Il-17rc-KO mice didn’t develop any skin papilloma. The skin papilloma formed never progressed into squamous carcinoma. However, centrinone, a selective inhibitor of PLK4, didn’t affect skin papilloma formation or epidermal thickening. In our psoriasis model, the epidermis thickness of Il-17rc-KO mice was dramatically decreased compared to WT and Il17ra(T779A)-KI mice. There was no significant difference between WT and Il17ra(T779A)-KI mice in terms of skin lesion and thickening of the epidermis. Centrinone didn’t stall the thickening of the epidermis in the psoriasis model. IHC staining showed significantly increased Ki67+ basal keratinocytes in the untreated skin of Il17ra(T779A)-KI male mice compared to WT mice. In imiquimod-treated skin, the percentage of Ki67+ basal keratinocytes significantly decreased in the order from WT, Il17ra(T779A)-KI to Il17rc-KO mice.
Conclusion
Our data suggest that the proliferation of keratinocytes is not stalled by centrinone but is inhibited by Il17rc-KO. Il17ra(T779A)-KI significantly inhibits skin papilloma formation, but slightly decreases epidermal thickening in the psoriasis model. However, Il17ra(T779A)-KI increases keratinocyte proliferation based on Ki67 staining in the untreated normal skin.

Abstract
Interferon-induced transmembrane protein 3 (IFITM3) is a restriction factor that limits viral pathogenesis and exerts poorly understood immunoregulatory functions. Here, using human and mouse models, we demonstrate that IFITM3 promotes MyD88-dependent, TLR-mediated IL-6 production following exposure to cytomegalovirus (CMV). IFITM3 also restricts IL-6 production in response to influenza and SARS-CoV-2. In dendritic cells, IFITM3 binds to the reticulon 4 isoform Nogo-B and promotes its proteasomal degradation. We reveal that Nogo-B mediates TLR-dependent pro-inflammatory cytokine production and promotes viral pathogenesis in vivo, and in the case of TLR2 responses, this process involves alteration of TLR2 cellular localization. Nogo-B deletion abrogates inflammatory cytokine responses and associated disease in virus-infected IFITM3-deficient mice. Thus, we uncover Nogo-B as a driver of viral pathogenesis and highlight an immunoregulatory pathway in which IFITM3 fine-tunes the responsiveness of myeloid cells to viral stimulation.

Abstract
The novel coronavirus pneumonia (COVID-19) is the world's most serious public health crisis, posing a serious threat to public health. In clinical practice, automatic segmentation of the lesion from computed tomography (CT) images using deep learning methods provides an promising tool for identifying and diagnosing COVID-19. To improve the accuracy of image segmentation, an attention mechanism is adopted to highlight important features. However, existing attention methods are of weak performance or negative impact to the accuracy of convolutional neural networks (CNNs) due to various reasons (e.g. low contrast of the boundary between the lesion and the surrounding, the image noise). To address this issue, we propose a novel focal attention module (FAM) for lesion segmentation of CT images. FAM contains a channel attention module and a spatial attention module. In the spatial attention module, it first generates rough spatial attention, a shape prior of the lesion region obtained from the CT image using median filtering and distance transformation. The rough spatial attention is then input into two 7 × 7 convolution layers for correction, achieving refined spatial attention on the lesion region. FAM is individually integrated with six state-of-the-art segmentation networks (e.g. UNet, DeepLabV3+, etc.), and then we validated these six combinations on the public dataset including COVID-19 CT images. The results show that FAM improve the Dice Similarity Coefficient (DSC) of CNNs by 2%, and reduced the number of false negatives (FN) and false positives (FP) up to 17.6%, which are significantly higher than that using other attention modules such as CBAM and SENet. Furthermore, FAM significantly improve the convergence speed of the model training and achieve better real-time performance. The codes are available at GitHub (https://github.com/RobotvisionLab/FAM.git).

Abstract
Objective JKAP modifies T‐cell immune response and inflammation, also involves in cardia‐cerebrovascular disease etiology. This study intended to explore JKAP's relation with T‐helper 1 (Th1), T‐helper 17 (Th17) cell levels, clinical properties, and recurrence‐free survival (RFS) in acute ischemic stroke (AIS) patients. Methods A total of 155 AIS patients were analyzed. Serum JKAP, interferon‐gamma (IFN‐γ), and interleukin‐17A (IL‐17A) were detected by ELISA; then blood Th1 and Th17 cells were quantified by flow cytometry. Besides, 30 healthy subjects were enrolled as controls to detect JKAP, Th1, and Th17 cells. Results JKAP level was lower (p < 0.001), Th1 cells were not differed (p = 0.068), but Th17 cells were elevated in AIS patients versus controls (p < 0.001). Meanwhile, JKAP was negatively correlated with Th1 cells (p = 0.038), Th17 cells (P<0.001), IFN‐γ (p = 0.002), and IL‐17A (p < 0.001) in AIS patients. JKAP was negatively associated with the National Institutes of Health Stroke Scale (NIHSS) score (p < 0.001), but Th17 cells (p = 0.001), IFN‐γ (p = 0.035), and IL‐17A (p = 0.008) levels were positively associated with NIHSS score. Additionally, accumulating RFS was numerically longer in patients with JKAP Quantile (Q) 4 than patients with JKAP Q1–Q3 (p = 0.068), and numerically better in patients with JKAP Q3–Q4 than patients with JKAP Q1–Q2 (p = 0.069), but without statistical significance. Conclusion JKAP correlates with lower Th1 and Th17 cell percentages as well as milder disease severity.

Abstract
Objective: To evaluate the application of real-time RT-PCR and semi-nested RT-PCR in the detection of norovirus in oysters and analyzing the genetic characteristics of the isolates. Methods: Real-time fluorescent RT-PCR and semi-nested RT-PCR were used to detect norovirus GⅠ/GⅡ in fresh oysters collected from the markets in Beijing from November 2014 to October 2015. The detection rate of the parallel test was also analyzed. In addition, the reliability of semi-nested RT-PCR was evaluated by agreement rate and consistency test (Kappa value). The positive products of norovirus GⅠ/GⅡ capsid protein region gene by semi-nested RT-PCR were sequenced. Software BioEdit 7.0.9.0 was used for sequence alignment, and software Mega 6.0 was used to construct the evolutionary tree. Results: In 72 samples, the detection rate of norovirus was 31.94% (23/72) by real-time RT-PCR, 38.89% (28/72) by semi-nested RT-PCR and 48.61% (35/72) by parallel test. The coincidence rate of the two methods was 73.61%, a moderate degree (Kappa value =0.43). A total of 13 norovirus strains were successfully sequenced, and 11 strains (7 GⅡ.17 strains, 2 GⅡ. 4 Sydney_ 2012 strains, 1 GⅡ. 1 strain and 1 GⅡ. 21 strain) were obtained from norovirus positive samples by two RT-PCR methods, two strains (1 GⅡ. 17 strain and 1 GⅡ. 3 strain) were obtained from real-time RT-PCR negative samples which were positive for norovirus by semi-nested RT-PCR. The similarity between these strains and reference strains from diarrhea patients, environmental sewage, and shellfish products were 84.4% - 100.0%. Conclusions: The parallel test of norovirus in oysters by two RT-PCR methods can improve the detection rate and detect more genotypes. Norovirus strains in oysters were highly homologous with reference strains from diarrheal patients, environmental sewage, and shellfish products. Therefore, surveillance, prevention and control for norovirus should be carried out in people who have frequent contacts with oysters and related environments.

Abstract
BACKGROUND The purpose of this study was to explore the influencing factors of serum uric acid (SUA) level and related gene polymorphisms in the healthy population. METHODS A total of 346 healthy individuals screened from different areas in Shenyang City and 195 patients with high SUA levels were included. RESULTS The levels of TC (total cholesterol), HDL-C (high-density lipoprotein cholesterol), LDL-C (low-density lipoprotein cholesterol), TG (triglycerides), GLU (blood glucose) ALT (alanine aminotransferase), TBA (total bile acid), TBIL (total bilirubin), CR (creatinine) and CYSC (Cystatin C) were statistically different between the healthy and hyperuricemia population (P<0.05). However, there was no statistical difference in the UA level between the two groups (P>0.05). After adjusting for UA, TC, HDL-C, LDL-C, GLU, TBIL and CYSC, the additive and recessive models of rs2231142 were statistically significant in females (P<0.05). For males, haplotypes of A-C-A-A-G-G, A-C-G-C-G-G and A-T-G-A-A-G had significant difference between the healthy and hyperuricemia population (P<0.05). For females, the haplotypes of A-C-G-C-G-G and A-T-A-C-A-T had significant differences (P<0.05). CONCLUSION The distributions of SLC2A9 (solute carrier family 2 and facilitated glucose transporter member 9), ABCG2 (ATP-binding cassette G2), GCKR (glucokinase regulatory protein), KCNQ1, IGFIR (Insulin-like growth factor-I receptor) and VEGFR (Vascular Endothelial Growth Factor Receptor) were balanced in the population in Shenyang City. The haplotypes of A-C-A-A-G-G, A-C-G-C-G-G and A-T-G-A-A-G were the influencing factors of high SUA in the population in Shenyang City.

Abstract
BACKGROUND Most patients with severe craniocerebral injury have gastrointestinal motility deficiency. When the body is exposed to external mechanical trauma, infection, vomiting, and gastric content reflux tend to occur, which causes early gastrointestinal dysfunction, affects nutrient intake, aggravates brain edema, delays wound healing, and is not conducive to the prognosis of patients. Mosapride is a commonly used gastrointestinal motility agent, which can improve gastrointestinal motility and speed up gastric emptying. Lactobacillus acidophilus can regulate the intestinal flora, protect the intestinal mucosal barrier, maintain intestinal balance, and relieve gastric motility. The purpose of this study was to investigate the effects of Lactobacillus acidophilus combined with mosapride treatment on the time to reach enteral nutrition standards, intestinal flora, rehabilitation process, and other aspects of patients with gastrointestinal dysfunction after craniocerebral injury, and to evaluate its clinical effects.
AIM To observe the clinical effects of Lactobacillus acidophilus combined with mosapride in the treatment of gastrointestinal dysfunction after craniocerebral injury.
METHODS A total of 92 patients with gastrointestinal dysfunction after craniocerebral injury at our hospital from February 2018 to February 2021 were selected and divided into a study group and a control group at a ratio of 1:1 using a random number table, with 46 cases in each group. On the basis of conventional treatment, the control group was given mosapride, and the study group was given Lactobacillus acidophilus combined with mosapride for 1 wk. The clinical efficacy, time to reach enteral nutrition standards, recovery progress, 28-d mortality rate, gastric motility indexes [intra-abdominal pressure (IAP) and residual gastric volume (GRA)], and intestinal motility before treatment and after 3 d and 1 wk of treatment were compared between the two groups. Intestinal barrier function indexes [D-lactic acid (D-LA) and diamine oxidase (DAO)] and intestinal flora (Bifidobacterium, Lactobacillus, Enterococcus, and Enterobacter) were also compared.
RESULTS The total effective rate of the study group was higher than that of the control group (93.48% vs 78.26%, P < 0.05). The time to reach enteral nutrition standards, time to mechanical ventilation, and the length of ICU stay in the study group were shorter than those of the control group (P < 0.05). There was no significant difference in the 28-d mortality rate between the two groups (P > 0.05). The APACHE II and SOFA scores of the study group were lower than those of the control group after 3 d and 1 wk of treatment, and the Glasgow Coma scale scores were higher than those of the control group (P < 0.05). The levels of IAP, GRA, D-LA, and DAO in the study group were lower than those of the control group after 3 d and 1 wk of treatment (P < 0.05). The numbers of Bifidobacterium and Lactobacillus in the study group were more than those of the control group after 3 d and 1 wk of treatment, and the numbers of Enterococcus and Enterobacter were less than those of the control group (P < 0.05).
CONCLUSION Lactobacillus acidophilus and mosapride are effective in treating gastrointestinal dysfunction after craniocerebral injury. They can shorten the time to reach enteral nutrition standards, adjust the intestinal flora, protect the intestinal mucosal barrier, promote the recovery of the gastrointestinal tract and nerve function, and accelerate the recovery process of patients.

Abstract
BACKGROUND Patients with esophageal cancer (EC) are prone to thoracic infection after surgery, but there is a lack of early prediction markers. Based on the fact that matrix metalloproteinase-9 (MMP-9), immature platelet ratio, macromolecular B lymphocytoma, and changes in lactate dehydrogenase levels are all related to infection, it was speculated that these changes may be candidate markers for clinical prediction of thoracic infection and sepsis.
AIM To investigate the expression of B-cell lymphoma-extra large (Bcl-xL) protein, lactate dehydrogenase (LDH), immature platelet fraction (IPF), and MMP-9 in chest infections after EC surgery and their role in predicting sepsis.
METHODS From February 2016 to October 2020, 187 patients with chest infection after EC surgery were selected as an observation group. The patients were divided into either a sepsis subgroup (16 cases) or a non-sepsis (171 cases) subgroup according to whether sepsis occurred. And 187 patients with no infection after EC surgery with matched clinical data during the same period were selected as a control group. The levels of Bcl-xL protein, LDH, IPF, and MMP-9 between the two groups and between patients with and without sepsis were compared. Pearson analysis was performed to investigate the relationship of Bcl-xL, LDH, IPF, and MMP-9 with the severity of sepsis. Logistic regression was used to analyze the factors related to sepsis. Receiver operating characteristic curve (ROC) was used to analyze the performance of Bcl-xL, LDH, IPF, and MMP-9 in predicting sepsis.
RESULTS Bcl-xL, LDH, IPF, and MMP-9 in the observation group were significantly higher than those in the control group (P < 0.05). The operation time was longer and the levels of Bcl-xL, LDH, IPF, and MMP-9 were significantly higher in patients with sepsis than in those without (P < 0.05). The levels of Bcl-xL, LDH, IPF, and MMP-9 were positively correlated with APACHE II score (P < 0.05). Logistic regression analysis showed that the risk of sepsis was 1.174, 2.883, 2.562, and 1.948 times lower in patients with Bcl-xL, LDH, IPF, and MMP-9 expression higher than the averages than in those with Bcl-xL, LDH, IPF, and MMP-9 expression lower than the average (P < 0.05). ROC analysis showed that the AUC of Bcl-xL protein, LDH, IPF, and MMP-9 combined to predict sepsis was 0.964, which was greater than those of any index alone (P < 0.05).
CONCLUSION The levels of Bcl-xL protein, LDH, IPF, and MMP-9 in patients with chest infection after EC operation are elevated, which are closely related to the progression of the disease. They have good predictive performance in predicting sepsis secondary to chest infection after EC operation, which is convenient for guiding clinical prevention and treatment programs.

Abstract
Abstract Human heart rhythm is mainly regulated and controlled by the sinoatrial node. Fibrosis plays an important regulating role in adjusting the structural and functional integrity of the sinoatrial node pacemaker complex. In physiological state, the fibrosis degree of sinoatrial node is negatively correlated with heart rate, positively correlated with age and heart size, and can maintain a relatively stable heart rate. Pathological fibrosis of sinoatrial node can induce various types of arrhythmias which can result in sudden death. Determination of the mechanisms related to sinoatrial node pathological fibrosis could provide a target for clinical treatment of sinoatrial node fibrosis and diagnosis basis for forensic pathologists. This paper reviews the main mechanism of sinoatrial node pathological fibrosis, including abnormal activation of cardiac fibroblast cells in sinoatrial node, hyperplasia of epicardial adipose tissue, calcium clock disorder, artery stenosis, etc., introduces the test methods, diagnostic criteria as well as its role in sudden cardiac death and discusses the potential application, to provide reference for relevant research and application.

Abstract
OBJECTIVES Antiretroviral therapy (ART) reduces the risk of tuberculosis (TB). We aimed to examine the association between ART coverage scale-up on the changes in TB incidence in Africa from 2000 to 2018. STUDY DESIGN The design of the study is a retrospective ecological study. METHODS Data for 54 countries were obtained from several institutional-based sources, including the World Health Organization, the Joint United Nations Programme on HIV/AIDS, and the World Bank. A fixed-effects regression method of longitudinal data analysis was used to estimate the association between ART coverage and changes in TB incidence rate during 2000-2018. Statistical analyses were conducted using STATA 15.0/IC. RESULTS The TB incidence declined significantly, by an average of 2.3% per year during 2000-2018. The highest significant declines occurred in eastern and southern Africa. In adjusted analysis, each 1% increase in ART coverage was associated with a 3.97 per 100,000 decline of TB incidence. However, the marginal effects of ART on overall population TB incidence was dependent on the prevalence of human immunodeficiency virus infection. CONCLUSIONS Investment in the widespread scale-up of ART may contribute to the control of the TB epidemic in Africa. However, interventions are also needed to augment the effect of ART on population TB incidence.

Abstract
OBJECTIVE The injuries of rotator cuff will cause the shoulder dysfunctions. Due to limited self-regeneration abilities of the tendon-bone part, rotator cuff injuries remain a clinical challenge. Previous studies have proposed many strategies for treating this disease. In this work, we aimed to combine different strategies to achieve better beneficial effects on tendon-bone repair. MATERIALS AND METHODS We isolated mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) and tested the effects of PRP on the gene expression, cell death resistance, and osteogenic differentiation of MSCs. Then, we utilized multiple strategies to treat rotator cuff injuries. We evaluated the expression of genes that related to tissue repair, bone formation, and tendon regeneration. We also tested the biomechanical property of repair tissues. RESULTS We found that the in-vitro co-culture with PRP endowed MSCs with enhanced production of growth factors, better osteogenic differentiation ability, and stronger ability to resist cell death. Next, we applied MSCs, PRP, and MSCs-PRP combined therapies in rat rotator cuff injury model to compare their therapeutic effects in vivo. Through biomechanical testing, we found that the combined therapy was most efficient to promote tissue regeneration and enhance the biomechanical property of the newly generated bone. CONCLUSIONS The combined treatment induced strongest signals related to angiogenesis, bone formation, and tendon generation in-situ. We demonstrated that the combination of MSCs and PRP synergistically promotes tendon-bone healing and holds great promise for the treatment of rotator cuff injuries.

Abstract
BACKGROUND Hepatic metastasis develops in ~ 50% of uveal melanoma (UM) patients with no effective treatments. Although GNAQ/GNA11 mutations are believed to confer pathogenesis of UM, the underlying mechanism of liver metastasis remains poorly understood. Given that profound epigenetic evolution may occur in the long journey of circulating tumor cells (CTCs) to distant organs, we hypothesized that EZH2 endowed tumor cells with enhanced malignant features (e.g., stemness and motility) during hepatic metastasis in UM. We aimed to test this hypothesis and explore whether EZH2 was a therapeutic target for hepatic metastatic UM patients. METHODS Expression of EZH2 in UM was detected by qRT-PCR, Western blotting and immunohistochemistry staining. Proliferation, apoptosis, cancer stem-like cells (CSCs) properties, migration and invasion were evaluated under circumstances of treatment with either EZH2 shRNA or EZH2 inhibitor GSK126. Antitumor activity and frequency of CSCs were determined by xenografted and PDX models with NOD/SCID mice. Hepatic metastasis was evaluated with NOG mice. RESULTS We found that EZH2 overexpressed in UM promoted the growth of UM; EZH2 increased the percentage and self-renewal of CSCs by miR-29c-DVL2-β-catenin signaling; EZH2 facilitates migration and invasion of UM cells via RhoGDIγ-Rac1 axis. Targeting EZH2 either by genetics or small molecule inhibitor GSK126 decreased CSCs and motility and abrogated the liver metastasis of UM. CONCLUSIONS These findings validate EZH2 as a druggable target in metastatic UM patients, and may shed light on the understanding and interfering the complicated metastatic process.

Abstract
OBJECTIVE Anterior cruciate ligament (ACL) injuries which cause knee disabilities remain a clinical challenge due to the compromised tendon-bone repair. Multiple strategies have been proposed to treat the tendon-bone injuries, and the combination of these therapies hold great potential to achieve synergistic effects. MATERIALS AND METHODS We built PLGA-BMP-2 (bone morphogenetic protein 2) system and confirmed the sustained release of BMP-2 both in vitro and in vivo. We then applied different therapies to treat rat ACL reconstruction. We collected the tissue sample and analyzed the BMP-2 concentration both in serum and in injured sites. We tested the mRNA expression of genes that were related to inflammation, tissue repair and bone formation in damaged tissues. We also analyzed the protein levels of some genes associated with tendon formation and check the function of newly generated bone through biomechanical test. RESULTS We found that, compared to monotherapies, simultaneous utilization of sustained BMP-2 release and platelet-rich fibrin (PRF) after anterior cruciate ligament reconstruction showed better therapeutic effects on tendon-bone healing in rat. This combined therapy efficiently enhanced the levels of growth factors that favor the angiogenesis and relieved the inflammatory responses in the injured sites. Of note, the combined therapy efficiently promoted the signals associated with bone formation and tendon regeneration. CONCLUSIONS We demonstrated that the combined therapy with BMP-2 and PRF achieves synergistic effects on tendon-bone healing and holds great potential for the treatment of ACL reconstruction.

Abstract
Plating battery electrodes typically deliver higher specific capacity values than insertion or conversion electrodes because the ion charge carriers represent the sole electrode active mass, and a host electrode is unnecessary. However, reversible plating electrodes are rare for electronically insulating nonmetals. Now, a highly reversible iodine plating cathode is presented that operates on the redox couples of I2 /[ZnIx (OH2 )4-x ]2-x in a water-in-salt electrolyte. The iodine plating cathode with the theoretical capacity of 211 mAh g-1 plates on carbon fiber paper as the current collector, delivering a large areal capacity of 4 mAh cm-2 . Tunable femtosecond stimulated Raman spectroscopy coupled with DFT calculations elucidate a series of [ZnIx (OH2 )4-x ]2-x superhalide ions serving as iodide vehicles in the electrolyte, which eliminates most free iodide ions, thus preventing the consequent dissolution of the cathode-plated iodine as triiodides.

Abstract
Abstract Objective To investigate the characteristics and patterns of factors such as victims' information, injury tools and time of occurrence of intentional injury cases in southwest China. Methods One thousand three hundred and forty intentional injury cases from several places in southwest China from 2014 to 2016 assessed as minor injury level Ⅱ and above had been randomly selected. Data on victims' information, motives, injury tools, sites of occurrence, time of occurrence, injured parts and degrees of injury were classified and gathered, and then association analyses of motives and types of injury tools as well as degrees of injury and injury tools were made. Results Most of the victims were young adults between 20-50 years (65.2%), male (82.3%), rural household registration (62.8%); the motives were mainly dispute (45.8%). Injury tools were mostly blunt (54.6%) or sharp (36.0%). Specifically, injuries were mostly made bare-handed (36.9%) and by cutting tools (33.2%); the cases mainly occurred in public areas (59.0%). Cases occurred more frequently in January (11.3%), February (13.1%), March (11.6%) and from 22:00 to 01:00 every night. Injuries mainly involved the craniofacial region. The wounds were mainly assessed as minor injury level Ⅱ (61.6%). There was statistical significance in the difference of types of injury tools among cases with different motives (P<0.05). There was statistical significance in the difference of the distribution of injury tools among cases with different degrees of injury (P<0.05). Conclusion The occurrence of intentional injury cases in southwest China has potential patterns and relevant influencing factors. Prevention and analysis of such cases need to be comprehensively considered from the aspects such as victims' information, injury tools and time of occurrence.
