Abstract
Background Risankizumab (RZB), an anti-IL-23 p19 inhibitor, was well-tolerated and superior to placebo (PBO) in inducing clinical remission and endoscopic response in patients (pts) with moderate-to-severe Crohn’s disease (CD) in two phase 3 studies at 12 weeks. Aims FORTIFY (NCT03105102), was a 52-week (wk) phase 3 double-blind, re-randomized responder withdrawal study that evaluated the efficacy and safety of continuing RZB as subcutaneous (SC) maintenance therapy versus withdrawal to placebo in pts achieving induction response to RZB Methods Week 12 IV RZB responders were re-randomized 1:1:1 to: RZB SC 360mg (N=141), RZB 180mg (N=157), or PBO (withdrawal from IV RZB; N=164) every 8wks for 52wks. Co-primary endpoints were clinical remission (per CD Activity Index [CDAI] (US); or stool frequency/abdominal pain score [SF/APS] (OUS) and endoscopic response at wk52. Other clinical and endoscopic endpoints, inflammatory biomarkers, RZB serum levels, and safety were assessed over time. Results Rates of clinical remission (CDAI, SF/APS) and clinical response were similar for RZB and PBO groups through wk24, with rates lower for PBO thereafter. At wk52, clinical remission (CDAI, SF/APS) and endoscopic response rates were significantly higher with RZB 360mg than PBO ( P<0.01); RZB 180mg was superior to PBO for clinical remission per CDAI and endoscopic response ( P<0.01). Endoscopic remission and deep remission rates increased over time with 360mg, remained steady with 180mg, and decreased with PBO. Mean fecal calprotectin (FCP) and C-reactive protein (CRP) levels decreased with SC RZB, but increased with PBO, over 52wks. Exposure-adjusted event rates (per 100 pts-years) of serious adverse event (AE) were generally similar among groups (360mg, 21.0 E/100PY and 180mg, 19.5 E/100PY vs PBO, 19.3 E/100PY), as were AEs leading to drug discontinuation (4.8 E/100PY and 2.4 E/100PY vs 3.7 E/100PY), and serious infections (6.0 E/100PY and 3.0 E/100PY vs 5.0 E/100PY). Conclusions In pts with moderate-to-severe CD, a robust pharmacodynamic effect on the IL-23 pathway after 12wks RZB IV induction was maintained with RZB SC maintenance therapy. The durability of RZB was demonstrated with high rates of efficacy over the 52-wk study. RZB was superior to PBO for achieving clinical remission and endoscopic response at wk52. Results for the more stringent endpoints (endoscopic remission\deep remission) and persistent improvements in inflammatory biomarkers are consistent with a dose response relationship. Continued RZB SC maintenance treatment was generally safe and well-tolerated. Funding Agencies AbbVie

Abstract
BACKGROUND Sexual dysfunction (SD) is an increasingly serious global problem that has adverse effects on the physical and mental health of patients. AIM This study aimed to investigate the prevalence of SD and its related factors in patients with chronic hepatitis B (CHB). METHODS A total of 673 outpatients with CHB from October 2019 to December 2020 were included in the analysis. Demographic and clinical information was collected at enrolment. The Arizona Sexual Experiences Scale was used to evaluate SD. OUTCOMES The primary outcome measure was the prevalence of SD in CHB patients and its associated factors. Secondary outcomes were the corresponding scores in five domains of ASEX: drive, arousal, lubrication and/or erection, orgasm and satisfaction from orgasm. RESULTS The average age of patients was 47.0 years, with 85.6% male and 88.1% with cirrhosis. The SD prevalence was 25.4% and was increased with the decrease in liver function reserve (Child-Pugh A vs Child-Pugh B: 24.6% vs 44.8%, P = .016), the progression of liver fibrosis (FIB-4 < 1.45, 1.45-3.25, and > 3.25: 21.3%, 26.5%, and 34.4%, respectively; P < .001), and the aggravation of depression (without, mild, and moderate to severe: 18.1%, 33.6%, and 34.2%, respectively; P < .001). In multivariate analysis, SD was independently correlated with female sex (OR: 5.627, 95% CI: 3.501 - 9.044, P < .001), liver fibrosis (OR: 1.730, 95% CI: 1.054 - 2.842, P = .030), depression (OR: 2.290, 95% CI: 1.564 - 3.354, P < .001), and frequent diarrhea and/or upper respiratory tract infection/urinary system infection (OR: 2.162, 95% CI: 1.313-3.560, P = .002). CLINICAL IMPLICATIONS This study revealed the current situation of SD in CHB patients in China, and appealed to clinicians to pay attention to the physical and mental health of the CHB patients. STRENGTHS AND LIMITATIONS This study has a large sample size and detailed demographic and clinical data. It evaluated the relationship between SD and liver function reserve and liver fibrosis degree, and compared gender differences of SD. However, this study is a cross-sectional study design and does not include healthy controls. The effects of conflicts between the couple, SD in a partner, antidepressants and hormone changes on SD were not analyzed. CONCLUSION SD in CHB patients was highly prevalent, and its prevalence increased significantly with the deterioration of liver function reserve, liver fibrosis and depression. Additional longitudinal studies are needed to further explore its causality. Xingmei L, Siru Z, Junhua Y, et al. Sexual Dysfunction in Patients with Chronic Hepatitis B: Prevalence and Risk Factors.

Abstract
BACKGROUND Whether serum hepatitis B virus (HBV) RNA associates with hepatocellular carcinoma (HCC) development in chronic hepatitis B (CHB) patients has not been fully elucidated. METHODS We enrolled 2974 patients receiving nucleos(t)ide analogues (NAs) from a prospective, observational CHB cohort to investigate the effect of serum HBV RNA, measured at study entry (baseline), on HCC development, using Cox regression analyses. RESULTS During median follow-up of 4.4 years, 90 patients developed HCC. Patients with detectable baseline HBV RNA (n=2072) exhibited significantly higher HCC risk than those with undetectable level (5-year HCC incidence estimated by Kaplan-Meier method: 4.1% versus 1.8%, P=0.007; adjusted hazard ratio [aHR]=2.21, P=0.005). HBV RNA levels of 609-99,999 and ≥100,000 copies/ml were associated with incrementally increasing HCC risk (aHR=2.15 and 3.05, respectively; P for trend=0.003), compared to undetectable level (<609 copies/ml). Moreover, patients with single-detectable either HBV DNA or RNA and double-detectable DNA and RNA had 1.57- and 4.02-fold higher HCC risk respectively, than those with double undetectable DNA and RNA (P for trend=0.001). CONCLUSION High-level HBV RNA is associated with increased HCC risk in NAs-treated patients. Achieving undetectable HBV RNA may contribute to better clinical outcomes, indicating it could be a valuable endpoint of anti-HBV treatment.

Abstract
Objective: To study the distribution and metabolism of toxicants in rats after phenol burn. Methods: In February 2019, SPF-grade healthy SD male rats were transdermally exposed to 6 mg/kg phenol to create a 5% body surface burn model of rats. High performance liquid chromatography was used to determine phenol content in rat plasma and kidney tissues after 0.25, 0.75, 2, 4, 8, 16, and 32 h, respectively. The kinetic parameters of phenol were calculated by DAS 2.0 software, and the kidney targeting of phenol was evaluated. Results: The area under the blood concentration-time curve at 0-8 h (AUC(0-8)) of the rat after phenol burn was (28.741±6.485) μg/ml·h, and the area under the blood concentration-time curve from 0 to infinite time (AUC(0-∞)) was (30.354±6.424) μg/ml·h, half-life (t(1/2)) was (2.111±0.632) h, peak concentration (C(max)) was (16.287±4.870) μg/ml, mean residence time (MRT) was (1.854±0.148) h. The target efficiency (DTE) of rat kidney was 2.91. Conclusion: Phenol burn rats have fast percutaneous absorption, rapid elimination of phenol, and have high clearance rate, short MRT, and weak substance accumulation. Phenol has relatively obvious selectivity to the kidneys.

Abstract
The green synthesis of silver nanoparticles (AgNPs) from biological waste, as well as their excellent antibacterial properties, is currently attracting significant research attention. This study synthesized AgNPs from different mango peel extract concentrations while investigating their characteristics and antibacterial properties. The results showed that the AgNPs were irregular with rod-like, spherical shapes and were detected in a range of 25 nm to 75 nm. The AgNPs displayed antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), showing a more significant impact when synthesized with 0.20 g/mL of mango peel extract. Therefore, the antibacterial effect of different diluted AgNP concentrations on the growth kinetic curves of E. coli and S. aureus after synthesis with 0.20 g/mL mango peel extract was analyzed. The results indicated that the AgNP antibacterial activity was higher against S. aureus than against E. coli, while the AgNP IC50 in these two strains was approximately 1.557 mg/mL and 2.335 mg/L, respectively. This research provides new insights regarding the use of postharvest mango byproducts and the potential for developing additional AgNP composite antibacterial materials for fruit and vegetable preservation.

Abstract
Background:Rituximab is an effective therapy for rheumatoid arthritis (RA) patients with inadequate responses to methotrexate (MTX)1, 2. However, it has not been registered or approved in China for the treatment of RA by far. HLX01, an approved rituximab biosimilar (demonstrated in Chinese patients with diffuse large B-cell lymphoma)3, is thus evaluated in this study for the benefits of Chinese RA patients.Objectives:This study aimed to evaluate the efficacy and safety of HLX01 plus MTX versus placebo plus MTX in Chinese patients with active RA who had inadequate responses to MTX.Methods:This was a randomised, double-blind, placebo-controlled phase 3 study conducted in China (NCT03522415). Eligible patients were randomised 2:1 to receive intravenous infusion of 2×1000 mg HLX01 or placebo on day 1 and day 15. Patients with inadequate responses at week 16 and 20 were allowed to receive rescue treatments. Patients were retreated with or switched to receive (if initially assigned to placebo) 2×1000 mg rituximab at the first day of week 24 and 26. The primary endpoint of this study was the American College of Rheumatology criteria (ACR) 20 response at week 24. Secondary efficacy endpoints were evaluated at week 12, 24, 36 and 48. The safety, pharmacokinetics, pharmacodynamics and immunogenicity of HLX01 were observed and analyzed throughout the study.Results:Between May 28, 2018 and Sep 11, 2020, a total of 275 patients (ITT set) were randomised and 263 patients without major protocol deviations were included in per-protocol set (PPS). At week 24, HLX01 showed statistically superior efficacy (p <0.001) to placebo (ACR20: 60.7% vs 35.9% in ITT set, 60.3% vs 37.1% in PPS). Secondary efficacy endpoints were also significantly improved in HLX01 group compared with placebo (Table 1). The overall incidence of serious treatment emergent adverse events (TEAEs), adverse drug reactions (ADRs), and TEAEs leading to drug discontinuation were similar among treatment groups, with the most common TEAE been upper respiratory tract infection before (18.1% vs 18.5%) or after (13.0% vs 12.3%) week 24. Serum concentrations, immunogenicity and pharmacodynamics were similar between HLX01 and placebo groups.Table 1.Results of secondary efficacy endpoints at week 12, 24, 36 and 48 in ITT set.DurationSecondary efficacy endpointsACR20 (%)ACR50 (%)ACR70 (%)DAS28-CRP(mean)HAQ-DI(mean)HLX01PlaceboHLX01PlaceboHLX01PlaceboHLX01PlaceboHLX01PlaceboBaseline5.495.431.401.45Week 1248.132.621.910.94.45.43.894.471.021.22Week 2460.735.936.618.515.312.03.394.370.871.22Week 3660.148.946.431.532.217.42.883.510.710.97Week 4873.862.055.240.239.927.22.823.510.721.03Conclusion:Comparing with placebo plus MTX, HLX01 plus MTX showed significantly improved clinical outcomes and comparable safety profiles in Chinese patients with moderately to severely active RA who had inadequate responses to MTX, demonstrating HLX01 in combination with MTX as a well-tolerated, safe and efficient treatment option.References:[1]Emery P, Deodhar A, Rigby WF, et al.

Abstract
High pressure homogenization (HPH) offers new opportunities for food pasteurization/sterilization. Escherichia coli and Staphylococcus aureus suspended in phosphate buffered saline (PBS) buffer, milk and apple juice at initial concentration of ~106 log10 CFU per ml were subjected to HPH treatments up to 200 MPa with inlet temperatures at 4-40°C. After HPH at 200 MPa with the inlet temperature at 40°C, the count of E. coli suspended in PBS, milk and apple juice reduced by 3·42, 3·67 and 3·19 log10 CFU per ml respectively while the count of S. aureus decreased by 2·21, 1·02 and 2·33 log10 CFU per ml respectively suggesting that S. aureus was more resistant. The inactivation data were well fitted by the polynomial equation. Milk could provide a protective effect for S. aureus against HPH. After HPH at 200 MPa with the inlet temperature at 20°C, the cell structure of E. coli was destroyed, while no obvious damages were found for S. aureus.

Abstract
Objective: To investigate the clinical, imaging and molecular characteristics of primary hyperoxaluria type 1 (PH1) in children and to sum up existing evidence for further understanding the phenotype-genotype correlation of infantile PH1. Methods: This retrospective analysis was based on the medical records of children with PH1 diagnosed by gene test in the Department of Nephrology, Guangzhou Women and Children's Medical Center from June 2016 to May 2019. Targeted exome sequencing was performed on tubular disease-related genes of the probands and Sanger sequencing was conducted to validate suspected pathogenic variants of family members. Logistic regression analysis of NC and CCr was adopted to show the relation between NC and renal function. The literature review was conducted, and the clinical, imaging and molecular biogenetic characteristics of the disease were analyzed and summarized. Results: A total of 7 children from 6 families were enrolled. The median age of onset was 5 months. The median age of diagnosis was 8 months. Five cases had progressed to end-stage renal disease (ESRD), one case had chronic kidney disease (CKD) stage 1, and the other one had CKD stage 2. Four cases died, one case maintained on hemodialysis, and the other two non-dialysis cases were followed up. Among the 7 cases, 4 patients had infantile PH1, 1 patient had child and adolescent type, 1 patient had family type and the other one had unknown classification. There were two siblings (the younger brother had uremia and the sister had normal renal function) who had the delayed diagnosis for 5 and 3 years respectively. All patients in this cohort had proteinuria and microscopic hematuria, but no patients had gross hematuria. Three cases had hypercalciuria. Comprehensive diagnostic imaging evaluation include CT scan, MR scan, radiography and ultrasound led to the diagnosis of nephrocalcinosis (NC) in 5 cases, including 4 cases of simple NL and 1 case of NC with nephrolithiasis (NL), 1 case of multiple NL and 1 case of microcrystal deposition in renal medulla. However, only one case of NC was identified by ultrasound, the other 4 cases of NC were identified by radiograph examination. In the logistic regression analysis involving NC and creatinine clearnce rate (CCr), the results showed that NC was an independent risk factor for renal dysfunction (OR 2.5, 95%CI 0.7-1.2, P<0.05). All the 7 cases had AGXT gene variant, including homozygous variant in 4 cases and compound heterozygous variant in 3 cases. A total of 9 variant genotypes were found, and exon 6 variants were found in 4 children. Among them, there were 3 cases with c.679_680delAA. To our knowledge, both c.679_680delAA and c.190A>T in the cohort have not been reported previously. Conclusions: Infantile PH1 is the most common type of PH1 in children, which progresses rapidly or even begins with renal failure, with poor prognosis. It is also highly heterogeneous in phenotype and genotype. NC is an independent risk factor leading to renal failure. Radiograph examination showed high specificity for the diagnosis of NC. At present, the misdiagnosis and delayed diagnosis of PH1 are still common in China. It is of great significance to carry out quantitative determination of uric oxalate in order to reduce the misdiagnosis rate and enhance follow-up technologies for evaluating the therapeutic effect.

Abstract
MicroRNAs (miRNAs) function by negatively regulating their target genes. Aberrant expression of baculoviral IAP repeat containing 5 (BIRC5) is associated with the tumor growth and metastasis, however, the clinical significance of miRNAs/BIRC5 axis in gastric cancer (GC) remains unknown. The association of BIRC5 or miR-195-5p/-218-5p expression levels with the clinicopathological characteristics and prognosis in patients with GC was analysed by using a tissue microarray and TCGA dataset. Pearson correlation analysis was used for analysing the correlation of BIRC5 with miR-195-5p/-218-5p expression in GC tissues. Cox proportional hazard regression model was conducted to assess whether BIRC5 or miR-195-5p/-218-5p was an independent prognostic factor in patients with GC. We found that BIRC5 expression levels were increased in GC tissues as compared with the adjacent normal tissues, and acted as an independent prognostic factor of tumor recurrence in patients with GC. Increased expression of BIRC5 was traceable to the dysregulation of miR-195-5p/-218-5p rather than its genetic and epigenetic alterations in GC tissues. MiR-195-5p/-218-5p displayed a negative correlation with BIRC5 expression, and acted as independent prognostic factors of poor prognosis in patients with GC. In conclusion, dysregulation of miR-195-5p/-218-5p/BIRC5 axis predicts a poor prognosis in patients with gastric cancer.

Abstract
OBJECTIVE More and more evidence has shown that the critical functions of long non-coding RNA (lncRNA) polymorphism in the carcinogenicity mechanism of a variety of cancers. The association between lncRNA HOX transcript antisense intergenic RNA (HOTAIR) polymorphism and the risk of head and neck squamous cell carcinoma (HNSCC) in Chinese population has not been reported. To investigated the effects of HOTAIR polymorphism on cancer susceptibility, the influence of HOTAIR variants on the risk of HNSCC was analyzed in this study. PATIENTS AND METHODS In this case-control study, the tagging SNPs (rs874945, rs4759314, and rs7958904) in HOTAIR gene were genotyped in Chinese population consisting of 366HNSCC cases and 732 controls. RESULTS It was found that rs4759314 was associated with a significantly increased risk of HNSCC in Chinese population [GG vs. AA: adjusted odds ratio (OR) = 1.23, 95% confidence interval (CI) = 1.01-1.50; additive model: OR = 1.21, 95%CI = 1.01-1.46]. However, there were no significant associations of rs874945 and rs7958904 with HNSCC risk. CONCLUSIONS HOTAIR rs4759314 may influence HNSCC susceptibility and serve as a diagnostic biomarker.

Abstract
Abstract
Background
Previous studies have shown that acetylation plays a critical role in regulating the progress of cardiovascular diseases by acetylated histone and non-histones protein. However, the global lysine acetylome during atrial fibrillation (AF) were not fully understood.
Purpose
The aim of the present study was to identify the underlying mechanisms of AF via profiling of the quantitative changes of global proteomics and lysine acetylome in the left atrial appendage (LAA) tissues from valvular heart disease patients with AF.
Methods
This study obtained LAA specimens from patients undergoing cardiac surgery for severe valvular heart disease. The LAA specimens were obtained from both 9 patients with AF and with sinus rhythm (SR). The changes of proteome and acetylome in the AF-LAA vs SR-LAA tissues were studied using dimethyl-labeling, HPLC fractionation, affinity enrichment, LC-MS/MS analysis, database Search and bioinformatic analysis. The acetylated levels of each lysine acetylated site were normalized on the basis of the corresponding protein abundance.
Results
The bioinformatic analysis indicates 294 up-regulated (AF/SR ratio >1.3) proteins and 169 down-regulated (AF/SR ratio <1/1.3) proteins in the AF-LAA vs SR-LAA were detected. Moreover, 3,880 sites in 1,044 proteins were quantified. Motif analysis of the identified acetylated peptides indicated that a total of 14 significantly enriched amino acid sequence motifs from −10 to +10 surrounding the acetylated lysine (Kac) were defined according to 3412 peptides from 1115 proteins. Among the quantified acetylated sites and proteins, 231 up-regulated acetylated sites in 130 proteins and 121 down-regulated acetylated sites in 74 proteins were detected. The enrichment-based clustering analysis showed that energy metabolism and cardiac contraction-related proteins were highly differentially expressed in the AF-LAA vs SR-LAA. Meanwhile, the protein-protein interaction network of the differentially expressed acetylated proteins demonstrated that there were 146 nodes and 569 interactions in the network and quite a lot of interactions in energy metabolism-related proteins and in cardiac contraction-related proteins. Furthermore, the acetylated levels of most differentially expressed energy metabolism-related proteins involving in oxidative phosphorylation, TCA cycle, respiratory ETC, fatty acid metabolism were up-regulated. On the contrary, the acetylated levels of most acetylated sites in differentially expressed cardiac contraction-related proteins including the key contraction proteins were down-regulated.
Interaction network of Ac-proteins
Conclusions
This study details and expands our understanding of the changes of proteome and lysine acetylome in the LAA tissues from valvular heart disease patients with AF. The data suggest important expression differences of acetylated proteins related to energy metabolism and cardiac contraction which may be involved in the matrix of AF formation and maintainence.

Abstract
HSV-1 is a mucosal and nerve pathogen, whose morbidity shows an increasing tendency. Although several antiviral drugs exist, there is no cure for viral latency for virtually all carriers. There is an urgent need for an HSV-1 vaccine to control infection and limit its spread and recurrence. The UL18 gene, encoding a vital component of capsids, is one of the essential genes of HSV-1. Deletion of UL18 from HSV-1 may be exploited as a new approach to develop an attenuated vaccine. The purpose of this study was to construct a DNA vaccine with a full-length UL18 gene deletion of the HSV-1 genome that can induce an effective immune response. A UL18-knockdown plasmid (BAC-HSV-1ΔUL18) was constructed using the bacterial markerless gene knockout system, consisting of the functional pREDI plasmid and BAC-HSV-1 plasmid. Mice were immunized weekly for 3 weeks, and at 1 week post immunization, blood and splenocyte samples of vaccinated and control groups of mice were prepared for immunogenicity assessment. The level of immune response was evaluated using a DTH assay, cytokine determination, and splenocyte proliferation assay. Combination of the pREDI plasmid and BAC-HSV-1 plasmid provides an effective bacterial markerless gene knockout system. Using two-step homologous recombination with the UL18 homologous recombination fragment constructed by multistep PCR amplification, BAC-HSV-1ΔUL18 plasmid vaccine was successfully constructed and was found to significantly enhance cellular immune responses.
