Abstract
Human induced pluripotent stem cell derived cardiac fibroblasts (hiPSC-CFs) play a critical role in modeling human cardiovascular diseases in vitro. However, current culture substrates used for hiPSC-CF differentiation and expansion, such as Matrigel and tissue culture plastic (TCPs), are tissue mismatched and may provide pathogenic cues. Here, we report that hiPSC-CFs differentiated on Matrigel and expanded on tissue culture plastic (M-TCP-iCFs) exhibit transcriptomic hallmarks of activated fibroblasts limiting their translational potential. To alleviate pathogenic activation of hiPSC-CFs, we utilized decellularized extracellular matrix derived from porcine heart extracellular matrix (HEM) to provide a biomimetic substrate for improving hiPSC-CF phenotypes. We show that hiPSC-CFs differentiated and expanded on HEM (HEM-iCFs) exhibited reduced expression of hallmark activated fibroblast markers versus M-TCP-iCFs while retaining their cardiac fibroblast phenotype. HEM-iCFs also maintained a reduction in expression of hallmark genes associated with pathogenic fibroblasts when seeded onto TCPs. Further, HEM-iCFs more homogenously integrated into an hiPSC-derived cardiac organoid model, resulting in improved cardiomyocyte sarcomere development. In conclusion, HEM provides an improved substrate for the differentiation and propagation of hiPSC-CFs for disease modeling.

Abstract
Aim This study aimed to assess the Pakistani hepatitis B patients' knowledge, attitudes, and practices towards hepatitis management and the impact of self-management on the quality of life of hepatitis B patients as well as the moderating role of stigmatization. Methods A cross-sectional study design was used, and the data was collected from a total of 432 hepatitis B positive patients through a self-designed questionnaire. The studied subjects consisted of men (n = 205, 47%), women (n = 165, 38%), and transgender (n = 62, 14%). The obtained data were statistically analyzed using SPSS software version 26.0 for Windows. Results The mean age of the study participants was 48. Knowledge has a significant positive relationship with hepatitis self-management and quality of life, whereas knowledge has a negative relationship with stigmatization. Furthermore, multivariate analysis revealed that men were more knowledgeable about the disease than women and transgender people (6.14 ± 2.08 vs. 3.23 ± 1.61 vs. 1.03 ± 0.73, F = 8.2**, p = .000). On the scale of attitude and practice, significant gender differences were found. Women had more experience with hepatitis self-management than men or transgender (4.21 ± 13.0 vs. 2.17 ± 6.02 vs. 0.37 ± 0.31, F = 6.21**, p = .000). The regression analysis showed that self-management has a positive association with quality of life (B = 0.36, p = .001). The moderation analysis revealed that stigmatization negatively moderates the relationship between self-management and quality of life (B = -0.53, p = .001). Conclusion Generally, patients had good knowledge about the disease and its self-management. However, a societal and community-level awareness campaign should be organized on the quality of life and stigmatization of people with chronic illness regarding their human rights, dignity, and physical, mental, and social well-being.

Abstract
BACKGROUND Randomized controlled trials have demonstrated that Songling Xuemaikang capsule (SXC) is effective in blood pressure (BP) lowering for essential hypertension. However, the effectiveness of SXC in real-world clinical practice remains unknown. We aimed to investigate whether the BP-lowering effectiveness of SXC in the real-world practice setting is comparable to the efficacy of the intervention in a randomized controlled trial. METHODS We included 1325 patients treated with SXC monotherapy from a real-world registry and 300 from the SXC-BP trial. A propensity score matching (PSM) approach was used to select participants from the two cohorts. The primary outcome was a change in the office of BP from baseline to 8 weeks. RESULTS After PSM, there were 552 patients for the comparative analysis. Clinically meaningful BP reductions were observed both in the real world and in the RCT cohorts after 8-week SXC treatment. The 8-week systolic/diastolic BP was 129.50/81.33 mm Hg vs. 134.97/84.14 mm Hg in the real-world population and the RCT population, respectively. The changes in systolic BP (15.82 ± 10.71 vs. 10.48 ± 10.24; P < .001), and diastolic BP (10.01 ± 7.73 vs. 7.75 ± 8.14; P = .001) from baseline to 8 weeks were significantly greater in the real-world population. CONCLUSION The current comparison demonstrated that SXC monotherapy is at least as effective in real-world settings as within the randomized controlled trial for BP lowering in patients with grade 1 hypertension.

Abstract
BACKGROUND Identifying existing care pathways is the first step for understanding how services can be improved to enable early diagnosis and effective follow-up care for non-communicable diseases (NCDs); however, evidence on how care pathways can and should be identified in low- and middle-income countries (LMICs) is lacking. OBJECTIVE To describe generalisability and lessons learned from recruitment and data collection for the quantitative component of a mixed methods study designed to determine the care pathway for atrial fibrillation (AF) in Brazil, China and Sri Lanka. METHODS Adults (≥18 years) that spoke the local language and with an AF diagnosis were eligible. We excluded anyone with a hearing or cognitive impairment or ineligible address. Eligible participants were identified using electronic records in Brazil and China; in Sri Lanka, researchers attended the outpatient clinics to identify eligible participants. Data were collected using two quantitative questionnaires administered at least 2-months apart. A minimum sample size of 238 was required for each country. RESULTS The required sample size was met in Brazil (n = 267) and China (n = 298), but a large proportion of AF patients could not be contacted (47% and 27%, respectively) or refused to participate (36% and 38%, respectively). In Sri Lanka, recruitment was challenging, resulting in a reduced sample (n = 151). Mean age of participants from Brazil, China and Sri Lanka was 69 (SD = 11.3), 65 (SD = 12.8) and 58 (SD = 11.7), respectively. Females accounted for 49% of the Brazil sample, 62% in China and 70% in Sri Lanka. CONCLUSIONS Generalisability was an issue in Brazil and China, as was selection bias. Recruitment bias was highlighted in Sri Lanka. Additional or alternative recruitment methods may be required to ensure generalisability and reduce bias in future studies aimed at identifying NCD care pathways in LMICs.

Abstract
BACKGROUND Nuts and algae have been shown to improve BP levels, but their effectiveness is controversial. AIMS This study aims to illustrate the effect of dietary pattern with nuts and algae-less on BP levels in children and adolescents from a cross-sectional study. METHODS A total of 5645 children from the Chongqing Children's Health Cohort, aged 9.34 ± 1.74 years with 52.05% males, were analyzed. Stratified analysis was conducted to explore the differences between the two dietary patterns in urban or rural areas, as well as the differences in different gender. Logistic regression was used to analyze the influence factors of increased BP. And a GLM was used to analyze the influence of the two dietary patterns on systolic blood pressure (SBP, mmHg), diastolic blood pressure (DBP, mmHg), and mean arterial pressure (MAP, mmHg). RESULTS Children with nuts and algae-less dietary patterns had higher SBP (104.68 ± 10.31 vs 103.81 ± 9.74, P = .006), DBP (64.27 ± 7.53 vs 63.55 ± 7.52, P = .002), and MAP (77.74 ± 7.75 vs 76.97 ± 7.52, P = .001) compared with those children with a balanced diet. After adjusting for covariates, the nuts and algae-less diet was a risk factor for hypertension in children when compared with the balanced diet(OR(95%CI):1.455(1.097,1.930), P = .009). The nuts and algae-less diet has a significant influence on SBP (104.68 ± 10.31 mmHg vs.103.81 ± 9.74 mmHg, P = .006). Stratified analysis by sex showed that nuts and algae-less dietary patterns had a more significant impact on females than males. CONCLUSION Nuts and algae-less dietary pattern correlated with increased BP levels in children, and a greater impact on SBP levels was found in females, suggesting that a balanced diet with appropriate nuts and algae should be proposed for children in China.

Abstract
Along with the typical biochemical alterations that occur during pregnancy, certain metabolic changes might be associated with the development of several psychiatric disorders, including postpartum depression (PPD), which is the most common type of psychiatric disorder during pregnancy or first postpartum year, and it develops in about 15% of women. Metabolomics is a rapidly developing discipline that deals with the metabolites as the final products of all genetically controlled biochemical pathways, highly influenced by external and internal changes. The aim of this paper was to review the published studies whose results suggest or deny a possible association between the fine regulation of the metabolome and PPD, enabling conclusions about whether metabolomics could be a useful tool in defining the biochemical pathways directly involved in the etiology, diagnosis and course of PPD. Beside numerous hormonal changes, a lot of different metabolic pathways have been discovered to be affected in women with PPD or associated with its development, including alterations in the energy metabolism, tryptophan and amino acid metabolism, steroid metabolism, purine cycle, as well as neurotransmitter metabolism. Additionally, metabolomics helped in defining the association between PPD and the exposure to various endocrine disrupting metabolites during pregnancy. Finally, metabolome reflects different PPD therapies and exposure of fetus or breastfed infants to pharmacotherapy prescribed to a mother suffering from PPD. This review can help in creating the picture about metabolomics' broad application in PPD studies, but it also implies that its potential is still not completely used.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Liensinine(Lien, C37H42N2O6) is an alkaloid compound from plumula nelumbinis that demonstrates an antihypertensive effect. The protective effects of Lien on target organs during hypertension are still unclear. AIM OF THE STUDY This study aimed to understand the mechanism of Lien during the treatment of hypertension, with emphasis on vascular protection. MATERIALS AND METHODS Lien was extracted and isolated from plumula nelumbinis for further study. In vivo model of Ang II-induced hypertension, non-invasive sphygmomanometer was used to detect the blood pressure in and out of the context of Lien intervention. Ultrasound was used to detect the abdominal aorta pulse wave and media thickness of hypertensive mice, and RNA sequencing was used to detect the differential genes and pathways of blood vessels. The intersection of Lien and MAPK protein molecules was detected by molecular interconnecting technique. The pathological conditions of abdominal aorta vessels of mice were observed by HE staining. The expression of PCNA, α-SMA, Collagen Type Ⅰ and Collagen Type Ⅲ proteins were detected by IHC. The collagen expression in the abdominal aorta was detected by Sirius red staining. The MAPK/TGF-β1/Smad2/3 signaling and the protein expression of PCNA and α-SMA was detected by Western blot. In vitro, MAPK/TGF-β1/Smad2/3 signaling and the protein expression of PCNA and α-SMA were detected by Western blot, and the expression of α-SMA was detected by immunofluorescence; ELISA was used to detect the effect of ERK/MAPK inhibitor PD98059 on Ang Ⅱ-induced TGF-β1secrete; and the detection TGF-β1and α-SMA protein expression by Western blot; Western blot was used to detect the effect of ERK/MAPK stimulant12-O-tetradecanoyl phorbol-13-acetate (TPA) on the protein expression of TGF-β1 and α-SMA. RESULTS Lien displayed an antihypertensive effect on Ang Ⅱ-induced hypertension, reducing the pulse wave conduction velocity of the abdominal aorta and the thickness of the abdominal aorta vessel wall, ultimately improving the pathological state of blood vessels. RNA sequencing further indicated that the differential pathways expressed in the abdominal aorta of hypertensive mice were enriched in proliferation-related markers compared with the Control group. The profile of differentially expressed pathways was ultimately reversed by Lien. Particularly, MAPK protein demonstrated good binding with the Lien molecule. In vivo, Lien inhibited Ang Ⅱ-induced abdominal aorta wall thickening, reduced collagen deposition in the ventral aortic vessel, and prevented the occurrence of vascular remodeling by inhibiting MAPK/TGF-β1/Smad2/3 signaling activation. In addition, Lien inhibited the activation of Ang II-induced MAPK and TGF-β1/Smad2/3 signaling, attenuating the expression of PCNA and inhibiting the reduction of α-SMA, collectively playing a role in the inhibition of Ang Ⅱ-induced hypertensive vascular remodeling. PD98059 alone could inhibit Ang Ⅱ-induced elevation of TGF-β1 and the decrease of α-SMA expression. Further, PD98059 combined with Lien had no discrepancy with the inhibitors alone. Simultaneously TPA alone could significantly increase the expression of TGF-β1 and decrease the expression of α-SMA. Further, Lien could inhibit the effect of TPA. CONCLUSION This study helped clarify the protective mechanism of Lien during hypertension, elucidating its role as an inhibitor of vascular remodeling and providing an experimental basis for the research and development of novel antihypertensive therapies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nonsteroidal anti-inflammatory drugs (NSAIDs) have been used clinically to treat inflammatory diseases clinically. However, the adverse effects of NSAIDs cannot be ignored. Therefore, it is critical for us to find alternative anti-inflammatory drugs that can reduce adverse reactions to herbal medicine, such as Iris tectorum Maxim., which has therapeutic effects and can treat inflammatory diseases and liver-related diseases. AIM OF THE STUDY This study aimed to isolate active compounds from I. tectorum and investigate their anti-inflammatory effects and action mechanisms. MATERIALS AND METHODS Fourteen compounds were isolated from I. tectorum using silica gel column chromatography, Sephadex LH-20, ODS and high performance liquid chromatography, and their structures were identified by examining physicochemical properties, ultraviolet spectroscopy, infrared spectroscopy, mass spectrometry, and nuclear magnetic resonance spectroscopy. Classical inflammatory cell models were established using lipopolysaccharide (LPS)-stimulated RAW264.7 cells and rat primary peritoneal macrophages to examine the effect of these compounds. To examine the action mechanisms, the nitric oxide (NO) levels were measured by Griess reagent and the levels of inflammatory cytokines in the supernatant were measured by ELISA; The expressions of major proteins in prostaglandin E2 (PGE2) synthesis and the nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways were examined by Western blotting, and the mRNA expression levels were measured by quantitative real-time polymerase chain reaction; and the nuclear translocation of p65 was examined by high content imaging. Molecular docking was used to predict the binding of active compound to target protein. RESULTS Our findings revealed that Iristectorigenin C (IT24) significantly inhibited the levels of NO and PGE2 without affecting cyclooxygenase (COX)-1/COX-2 expression in LPS-induced RAW264.7 cells and rat peritoneal macrophages. Furthermore, IT24 was shown to decrease the expression of microsomal prostaglandin synthetase-1 (mPGES-1) in LPS-induced rat peritoneal macrophages. IT24 did not suppress the phosphorylation and nuclear translocation of proteins in the NF-κB pathway, but it inhibited the phosphorylation of p38/JNK in LPS-stimulated RAW264.7 cells. Additionally, molecular docking analysis indicated that IT24 may directly bind to the mPGES-1 protein. CONCLUSION IT24 might inhibit mPGES-1 and the p38/JNK pathway to exert its anti-inflammatory effects and could be also developed as an inhibitor of mPGES-1 to prevent and treat mPGES-1-related diseases, such as inflammatory diseases, and holds promise for further research and drug development.

Abstract
PURPOSE To evaluate the validity of spot urine assay methods in estimating the 24-h urinary sodium, potassium and sodium-to-potassium ratio during three different sodium diets. MATERIALS AND METHODS Twelve healthy volunteers were asked to adhere to 3 dietary sodium targets (3.3-5.0g/day,<3.3 g/day and >5.0 g/day) for three consecutive weeks and to measure salt excretion daily in spot urine samples using a self-monitoring device. On day 7 of each week, 24-h urine was collected to compare measured with estimated 24-h salt excretion (by the Kawasaki, Tanaka and INTERSALT equations). RESULTS Correlation coefficients relating measured and estimated 24-h sodium excretion were low and not significant for Kawasaki and INTERSALT and moderate for the Tanaka equation (τ 0.56-0.64,p<.05). Bland-Altman plots showed considerable differences between estimated and measured sodium excretion across all salt diets. Over 40% of the participants showed an absolute difference between measured and estimated 24-h sodium of more than 1000 mg/day. The correlation coefficients between 24-h and spot Na/K ratio were 0.67, 0.94 and 0.85(p<.05), and mean differences were 0.59, 0.06 and 0.48 for the intermediate, low and high sodium diets, respectively. CONCLUSION These findings do not support estimation of individual 24-h salt excretion from spot urine by the Kawasaki, Tanaka, or INTERSALT formula. Plain language summaryAccurate monitoring of salt intake is essential to improve BP control. At present, measurement of sodium and potassium excretion in multiple non-consecutive 24-h urinary collections is considered the gold standard for measuring dietary sodium intake. However, this method is burdensome, time-consuming and error prone.Therefore, we assessed and compared the validity of three formula-based approaches to estimate 24-h urinary sodium and potassium excretion and the Na/K ratio from spot urine samples measured by a self-monitoring device under three different sodium diets using 24-h urine collections as the reference.We conclude that use of three commonly used equations that estimate 24-h urinary sodium and potassium excretion result in substantial bias, poor precision and poor accuracy and are therefore not recommended. The Na/K ratio based on multiple casual urine samples may be a useful, low-burden, low-cost alternative method to 24-h urine collection for monitoring daily salt intake.

Abstract
Migration from one location to another often comes with a change in environmental conditions. Here, we analysed features of DNA methylation in young, adult British-Bangladeshi women who experienced different environments during their childhoods: a) migrants, who grew up in Bangladesh with exposure to comparatively higher pathogen loads and poorer health care, and b) second-generation British-Bangladeshis, born to Bangladeshi parents, who grew up in the UK. We used buccal DNA to estimate DNA methylation-based age (DNAm age) from 14 migrants and 11 second-generation migrants, aged 18-35 years. 'AgeAccel,' a measure of DNAm age, independent of chronological age, showed that the group of women who spent their childhood in Bangladesh had higher AgeAccel (P = 0.028), compared to their UK peers. Since epigenetic clocks have been proposed to be associated with maintenance processes of epigenetic systems, we evaluated the preference for concordant DNA methylation at the luteinizing hormone/choriogonadotropin receptor (LHCGR/LHR) locus, which harbours one of the CpGs contributing to Horvath's epigenetic clock. Measurements on both strands of individual, double-stranded DNA molecules indicate higher stability of DNA methylation states at this LHCGR/LHR locus in samples of women who grew up in Bangladesh. Together, our two independent analytical approaches imply that childhood environments may induce subtle changes that are detectable long after exposure occurred, which might reflect altered activity of the epigenetic maintenance system or a difference in the proportion of cell types in buccal tissue. This exploratory work supports our earlier findings that adverse childhood environments lead to phenotypic life history trade-offs.

Abstract
Objective To investigate the prognostic value of illness perception (IP) on knee pain, quality of life (QoL) and functional level in elderly individuals reporting knee pain. Design A prospective cohort study of 1552 elderly with knee pain comparing two previously established clusters based on the Brief Illness Perception questionnaire. Cluster 1 ("Concerned optimists" [hypothesized unfavorable profile]; n = 642) perceived their knee pain as a greater threat to them than Cluster 2 ("Unconcerned confident" [hypothesized favorable profile]; n = 910). Primary outcome was the change from baseline to year 2 in the KOOS Pain subscale. Secondary outcomes were changes from baseline in quality of life (EuroQol-5 Domain and EQ VAS) and in the KOOS subscales Symptom, Activities of Daily Living, Knee-related QoL and Sports and recreation. Analyses were done on the original Intention-To-Survey (ITS) population, using repeated measures mixed linear models. Results Among the ITS population, 841 (54%) responded to the 2-year survey. There was a statistically significant but clinically irrelevant cluster difference in the 2-year change from baseline in KOOS pain (mean difference: 6.0 KOOS points [95% CI: 7.3 to -4.7]) explained by a minor improvement in Cluster 1: (6.2 points) and no changes in Cluster 2: (0.2 points). Comparable results were found across the secondary outcomes. Clinically irrelevant cluster changes in IP were seen. Conclusion In a cohort of people with knee pain, IP phenotype (i.e., Clusters) were of no prognostic value for the 2-year changes in pain, function, and QoL. Targeting IP may not be relevant in this patient population. Trial registration number and date of registration The Frederiksberg Cohort study was pre-registered at clinicaltrials.gov (NCT03472300) on March 21, 2018.
