Abstract
Ayurveda can be traced back to 3000BC. It is the principal part of traditional medicine in India and other South Asian countries. It was divided into four historical periods according to the academic circle in India, ie. the Vedic period, the Samhita period, the Sangraha period and the modern period. The literature in the Vedic period mainly included Vedic Samhitas Brahmanas, Ramayana, Mahabharata. In the Samhita period, the "BrihatTrayee", namely, Caraka Samhita, Susruta Samhita and Astanga Hrdaya Samhita were published, indicating that Ayurveda had developed into a full-fledged medical system. In the Sangraha period, the "Laghu Trayee", namely, Madhava Nidana, Sarangadhara Samhita and Bhava Prakasa were published. At this time, a large number of annotated texts for these medical books emerged, which kept driving Ayurveda improvements. Since the modern period, Ayurvedic classical works were rearranged, edited and translated into different languages as cultural heritage, drawing attention worldwide. While the research to these works has been conducted widely in China, they are still short of systematic and professional translation and in-depth studies. This paper attempts to introduce the literature related to Ayurveda systematically, to pave the way for further research of Ayurvedic literature in the field of traditional Chinese medicine.

Abstract
Objective: To simulate and evaluate the scraping and grinding work of workers with different spinal anteversion angles, and to explore the effects of different anteversion angles on the erector spinae muscles of scrapers. Methods: In November 2019, 16 male college student volunteers were recruited to simulate workers' scraping and grinding work. The parameters were 25°, 15 times/min, 15°, 30 times/min, 5°, 60 times/min respectively. The surface electromyography (sEMG) was used to collect the electromyographic signals of the erector spinae muscles, and the surface electromyographic characteristics of the erector spinae muscles were evaluated with Borg Scale. Results: There were significant differences between the maximum voluntary contraction percentage (MVE%) of the left and right erector spinae muscles groups in the three groups with different spinal anteversion angles (F(left)=13.41, P(left)<0.001; F(right)=4.74, P(right)=0.005) , and the EMG amplitude was higher at 25°, 15 times/min. At 15°, 30 times/min, MVE% of the left side was significantly higher than that of the right side (t=2.58, P=0.021) . There was significant difference in the mean power frequency (MPF) of the right erector spinae muscle in the three groups (F=9.42, P<0.001) , but there was no significant difference in the MPF of the left erector spinae muscle (F=0.30, P=0.823) . The fitting line showed that the left erector spinae muscle showed a downward trend at 5°, 60 times/min (t=-5.39, P=0.012) . Conclusion: Scrapers are less likely to be fatigued when the posture is 15°, 30 times/min, but they are more likely to be fatigued when working at 5°, 60 times/min.

Abstract
Objective: To screen the physical, psychological and behavioral factors related to patients with temporomandibular disorders (TMD) by using Axis Ⅱ assessment instruments of diagnostic criteria for TMD(DC/TMD). And to provide a reference to establish personalized diagnosis and treatment plans for TMD patients so as to prevent TMD and reduce predisposing factors. Methods: A total of 141 TMD patients, who were admitted in the Department of Oral and Maxillofacial Surgery in School and Hospital of Stomatology, Wuhan University from October 2018 to February 2021 were selected. There were 121 females and 20 males, with an average age of 30 years. A total of 90 healthy people were included as controls. A full-time psychologist conducted relevant questionnaire surveys. The questionnaires include general clinical survey forms and TMD symptom questionnaire. In addition, Axis Ⅱ assessment instruments include graded chronic pain scale, jaw functional limitation scale, oral behaviors checklist, patient health questionnaire-9 (depression), generalized anxiety disorder scale, patient health questionnaire-15 (physical symptoms), etc. The main observational indicators include: pain level, pain impact rates, overall classification of chronic pain, limited chewing function score, limited motor function score, limited communication function score, total jaw function restricted score, depression score, anxiety score, somatic symptom score and oral behavior score.The survey data were imported into SPSS 22.0 software for statistical analysis. Results: In the TMD group 60.3% (85/141) patients had various degrees of pain, 24.1% (34/141) of those with pain effect grades from 1 to 3 and 61.0% (86/141) showed chronic pain overall grades from Ⅰ to Ⅳ. The chewing function restricted score was 2.67(1.17, 4.25), motor function restricted score was 4.25(1.75, 6.12), communication function restricted score was 1.13(1.00, 2.25) and total jaw function restricted score was 2.56(1.47, 4.15) respectively. Patients with mild depression or above accounted for 59.6%(84/141), patients with mild anxiety or above accounted for 56.7%(80/141), 46.1%(65/141) patients had somatization symptoms. Statistical differences (P<0.05) were determined between TMD group and control group in various scores of jaw function, oral behavior grading, depression, anxiety, and physical symptoms. Physical symptoms had significantly statistical difference between different diagnostic classification(P<0.05). Meanwhile, among the different chronic pain levels in the TMD group, there were statistical differences in the various scales of mandibular dysfunction, depression, anxiety, and somatization. In the TMD group, other significant differences were noticed between males and females in terms of the average score of mouth opening, verbal and facial communication, the total score of mandibular dysfunction as well as physical symptoms (P<0.05). Conclusions: Compared with the healthy people, patients with TMD had more abnormal oral behaviors, different restriction of the mandibular functional activities. At the same time, depression, anxiety, and somatization were more serious. Patients with osteoarthritis and subluxation of temporomandibular joint were more likely to suffer physical symptoms. TMD patients suffering from pain had more severe mandibular dysfunction and symptoms of depression, anxiety, and somatization.

Abstract
Covering: up to 2021Self-resistance mechanisms adopted by natural product producers have long been recognized and studied as a standalone system separated from the assembly machinery. However, as more examples of self-resistance have been characterized in detail, it has been revealed that self-resistance could associate with the assembly machinery to fulfill the task of biosynthesis. This review summarizes different self-resistance mechanisms showing a common feature: intersection with natural product assembly. Furthermore, their possible evolutionary origin and synthetic biology applications are discussed.

Abstract
Objective: To investigate the efficacy and safety of infliximab (IFX) therapy for children with Kawasaki disease. Methods: Sixty-eight children with Kawasaki disease who received IFX therapy in Children's Hospital of Fudan University from January 2014 to April 2021 were enrolled. The indications for IFX administration, changes in laboratory parameters before and after IFX administration, response rate, drug adverse events and complications and outcomes of coronary artery aneurysms (CAA) were retrospectively analyzed. Comparisons between groups were performed with unpaired Student t test or Mann-Whitney U test or chi-square test. Results: Among 68 children with Kawasaki disease, 52 (76%) were males and 16 (24%) were females. The age of onset was 2.1 (0.5, 3.8) years. IFX was administered to: (1) 35 children (51%) with persistent fever who did not respond to intravenous immunoglobulin (IVIG) or steroids, 28 of the 35 children (80%) developed CAA before IFX therapy; (2) 32 children (47%) with continuous progression of CAA; (3) 1 child with persistent arthritis. In all cases, IFX was administered as an additional treatment (the time from the onset of illness to IFX therapy was 21 (15, 30) days) which consisted of second line therapy in 20 (29%), third line therapy in 20 (29%), and fourth (or more) line therapy in 28 (41%). C-reactive protein (8 (4, 15) vs. 16 (8, 43) mg/L, Z=-3.38, P=0.001), serum amyloid protein A (17 (10, 42) vs. 88 (11, 327) mg/L, Z=-2.36, P=0.018) and the percentage of neutrophils (0.39±0.20 vs. 0.49±0.21, t=2.63, P=0.010) decreased significantly after IFX administration. Fourteen children (21%) did not respond to IFX and received additional therapies mainly including steroids and cyclophosphamide. There was no significant difference in gender, age at IFX administration, time from the onset of illness to IFX administration, the maximum coronary Z value before IFX administration, and the incidence of systemic aneurysms between IFX-sensitive group and IFX-resistant group (all P>0.05). Infections occurred in 11 cases (16%) after IFX administration, including respiratory tract, digestive tract, urinary tract, skin and oral infections. One case had Calmette-Guérin bacillus-related adverse reactions 2 months after IFX administration. All of these adverse events were cured successfully. One child died of CAA rupture, 6 children were lost to follow up, the remaining 61 children were followed up for 6 (4, 15) months. No CAA occurred in 7 children before and after IFX treatment, while CAA occurred in 54 children before IFX treatment. CAA regressed in 23 (43%) children at the last follow-up, and the diameter of coronary artery recovered to normal in 10 children. Conclusion: IFX is an effective and safe therapeutic choice for children with Kawasaki disease who are refractory to IVIG or steroids therapy or with continuous progression of CAA.

Abstract
INTRODUCTION Osteoarthritis (OA) is one of the most common joint diseases in the elderly population. Proinflammatory cytokines, such as Interleukin-1β (IL-1β), play an important role in the development and progression of OA. Dapansutrile is a specific inhibitor of the NOD-like receptor protein 3 (NLRP3) inflammasome and exhibits anti-inflammatory properties. METHODS In this study, we investigated the protective effect and the underlying mechanism of dapansutrile on cartilage degeneration in vitro and in vivo. In the present study, chondrocytes were isolated from rats and then were treated with dapansutrile. After that, the expression of (Cox-2, inducible nitric oxide synthase (iNOS), Mmp-3, Mmp-9, Mmp-13 and IL-10) were evaluated at RNA level, then the expression of (COX-2, MMP-3, MMP-9, MMP-13, SOX-9 and COL2) were evaluated at protein level. Subsequently, the activation of the mitogen-activated protein kinase (MAPK) pathway was tested using western blotting (WB). Additionally, the rat OA model was developed to evaluate the protective effects of dapansutrile in vivo. RESULTS The results showed that dapansutrile had no obvious cytotoxicity on rat chondrocytes at 24 h (0, 1, 2, 5 and 10 μM). Dapansutrile significantly decreased IL-1β-induced upregulation of COX2, iNOS, matrix metalloproteinase 3 (MMP3), 9 (MMP9) and 13 (MMP13), and reversed IL-1β-induced the downregulation of IL-10, SOX9 and COL2. Dapansutrile also inhibited IL-1β-induced upregulation of the MAPK signaling pathway by downregulating the expression levels of phospho-ERK, and phospho-P38 in a concentration dependent manner. In addition, dapansutrile exhibited protective effects in rat OA model with lower Mankin's score and Osteoarthritis Research Society International (OARSI) score. CONCLUSION Our study suggested that dapansutrile effectively inhibited chondrocyte inflammation by suppressing MAPK signaling pathway in vitro, and ameliorated cartilage degeneration in vivo, indicating an anti-inflammatory effect in OA treatment.

Abstract
CONTEXT Ruminant livestock make an important contribution to global food security by converting feed that is unsuitable for human consumption into high value food protein, demand for which is currently increasing at an unprecedented rate because of increasing global population and income levels. Factors affecting production efficiency, product quality, and consumer acceptability, such as animal fertility, health and welfare, will ultimately define the sustainability of ruminant production systems. These more complex systems can be developed and analysed by using models that can predict system responses to environment and management. OBJECTIVE We present a framework that dynamically models, using a process-based and mechanistic approach, animal and grass growth, nutrient cycling and water redistribution in a soil profile taking into account the effects of animal genotype, climate, feed quality and quantity on livestock production, greenhouse gas emissions, water use and quality, and nutrient cycling in a grazing system. METHODS A component to estimate ruminant animal growth was developed and integrated with the existing components of the SPACSYS model. Intake of herbage and/or concentrates and partitioning of the energy and protein contained in consumed herbage and/or concentrates were simulated in the component. Simulated animal growth was validated using liveweight data from over 200 finishing beef cattle and 900 lambs collected from the North Wyke Farm Platform (NWFP) in southwest England, UK, between 2011 and 2018. Annual nitrous oxide (N2O), ammonia, methane and carbon dioxide emissions from individual fields were simulated based on previous validated parameters. RESULTS AND CONCLUSIONS A series of statistical indicators demonstrated that the model could simulate liveweight gain of beef cattle and lamb. Simulated nitrogen (N) cycling estimated N input of 190 to 260 kg ha-1, of which 37-61% was removed from the fields either as silage or animal intake, 15-26% was lost through surface runoff or lateral drainage and 1.14% was emitted to the atmosphere as N2O. About 13% of the manure N applied to the NWFP and excreta N deposited at grazing was lost via ammonia volatilisation. SIGNIFICANCE The extended model has the potential to investigate the responses of the system on and consequences of a range of agronomic management and grazing strategies. However, modelling of multi-species swards needs to be validated including the dynamics of individual species in the swards, preferential selection by grazing animals and the impact on animal growth and nutrient flows.

Abstract
Objective: To investigate the correlation between intrahepatic triglyceride content (IHTC) and glucose metabolism in patients with non-alcoholic fatty liver disease (NAFLD) diagnosed by proton magnetic resonance spectroscopy (1H-MRS). Methods: A total of 239 subjects without diabetes mellitus were previously enrolled and underwent 1H-MRS scans. Anthropometric indexes including height, weight, waist and blood pressure, and laboratory findings as plasma glucose (PG), insulin (INS), C-peptide (CP), liver enzymes [alanine aminotransferase (ALT), aspartate transaminase (AST), γ-glutamyl transpeptidase (GGT)] and lipid profiles were collected. According to IHTC levels, participants were divided into three groups: the non-NAFLD group (IHTC<5.56%), the mild NAFLD group (IHTC 5.56%-<33%), and the moderate and severe NAFLD group (IHTC ≥ 33%). The clinical characteristics of each group were analyzed, and the correlation between IHTC and glucose metabolism were assessed. Results: Compared with those in the non-NAFLD group, male proportion, waist, 120 min postprandial PG (PG120), CP, liver enzymes and total cholesterol (TC) levels were greater in the NAFLD group, whereas insulin sensitivity index-Cederholm (ISI-Cederholm) and high density lipoprotein cholesterol (HDL-C) levels were lower in the NAFLD groups. Subjects in the moderate and severe NAFLD group had higher levels of 120 min postprandial INS (INS120) and Stumvoll indexes, and lower ISI-Cederholm than those in the mild NAFLD group [80.37 (57.68, 112.70) mU/L vs.110.50(71.78, 172.80)mU/L, 1453(1178, 1798)vs.1737(1325, 2380), 358(297, 446) vs.441(318, 594), 2.27(2.01, 2.53) vs.2.06(1.81, 2.39), respectively, all P<0.05]. Correlation analyses showed that IHTC was significantly positively correlated with waist hip ratio (WHR), PG120, INS120, HOMA insulin resistance (HOMA-IR), Stumvoll 1st-insulin secretion, Stumvoll 2nd-insulin secretion, ALT, AST, GGT and TC (r=0.197, 0.274, 0.334, 0.162, 0.199, 0.211, 0.406, 0.361, 0.215, and 0.196, respectively, all P<0.05), and negatively correlated with ISI-Cederholm and HDL-C (r=-0.334, and-0.237, respectively, all P<0.05). Furthermore, a multiple linear stepwise regression analysis indicated that ISI-Cederholm (Standardized β =-0.298, P<0.001) and Stumvoll 1st insulin secretion (Standardized β = 0.164, P = 0.024) were independent factors of IHTC. Conclusions: Peripheral insulin resistance occurs in the early stage of NAFLD and becomes worse with the progression of the disease. IHTC was independently associated with insulin sensitivity and first-phase insulin secretion.

Abstract
Objective: To investigate the correlation between UGT1A1 polymorphisms and the irinotecan plus S-1 regimen-induced toxicities in Chinese advanced esophageal squamous cell carcinoma (ESCC) patients. Methods: A total of 46 recurrent or metastatic ESCC patients selected from ESWN 01 trial were randomly assigned to irinotecan plus S-1 group [intravenous infusion of irinotecan (160 mg/m(2)) on day 1 and oral S-1 (80-120 mg) on days 1-10, repeated every 14 days]. Peripheral venous blood at baseline was collected and genomic DNA was extracted. The genetic polymorphisms of UGT1A1*6 and UGT1A1*28 were analyzed by polymerase chain reaction (PCR) amplification. Irinotecan plus S-1 regimen-induced toxicities of patients with different UGT1A1 polymorphisms were observed. The correlation between UGT1A1 polymorphisms and the adverse effects was analyzed. Results: Among the 46 patients, the numbers of UGT1A1*6 wild type genotype (GG), mutant heterozygote (GA) and mutant homozygote (AA) were 30, 15 and 1, while those with UGT1A1*28 wild type genotype (TA6/6), mutant heterozygote (TA6/7) and mutant homozygote (TA7/7) were 36, 8 and 2, respectively. Only one patient with UGT1A1*6 AA genotype occurred grade 3 diarrhea, while one of the 2 patients with UGT1A1*28 TA7/7 genotype occurred grade 4 diarrhea. No neutropenia was observed in the patient with UGT1A1*6 AA genotype, however, both of the two patients with UGT1A1*28 TA7/7 genotype occurred grade 3-4 neutropenia. Patients with UGT1A1*28 genetic polymorphism (TA 6/7 or TA7/7) had a higher response rate compared with wild-type TA6/6 carriers. (55.6% versus 26.5%). Conclusions: The homozygous genotype of UGT1A1*6 AA and UGT1A1*28 TA7/7 are rare (<5%) in Chinese ESCC population. Not all homozygous AA and TA7/7 carriers occur severe dose limited toxicities (DLT) when treated with irinotecan (160 mg/m(2)) plus S-1 regimen for 2 weeks. However, it's still necessary torigorously observe the occurrence of severe diarrhea and neutropenia in patients with UGT1A1*6 AA and UGT1A1*28 TA7/7 and adjust the dose timely.

Abstract
Male urethral diverticula with calculi have a low incidence. It is extremely rare when the diverticulum accompanied with carcinoma. We report a case of diverticulum of the male urethra containing giant calculi which developed into squamous cell carcinoma. The patient initially presented with lower urinary tract symptoms and a hard, painless perineal mass. We believe that the process of diagnosis and treatment is of great significance in clinical practice.

Abstract
We present a table-top extreme ultraviolet (XUV) beamline for measuring time- and frequency-resolved XUV-excited optical luminescence (XEOL) with additional femtosecond-resolution XUV transient absorption spectroscopy functionality. XUV pulses are generated via high-harmonic generation using a near-infrared pulse in a noble gas medium and focused to excite luminescence from a solid sample. The luminescence is collimated and guided into a streak camera where its spectral components are temporally resolved with picosecond temporal resolution. We time-resolve XUV-excited luminescence and compare the results to luminescence decays excited at longer wavelengths for three different materials: (i) sodium salicylate, an often used XUV scintillator; (ii) fluorescent labeling molecule 4-carbazole benzoic (CB) acid; and (iii) a zirconium metal oxo-cluster labeled with CB, which is a photoresist candidate for extreme-ultraviolet lithography. Our results establish time-resolved XEOL as a new technique to measure transient XUV-driven phenomena in solid-state samples and identify decay mechanisms of molecules following XUV and soft-x-ray excitation.

Abstract
High-entropy alloys (HEAs) have been reported to have superior ability in hydrogen (H) storage and strong resistance to H embrittlement. These exceptional properties are directly related to the H solution in the HEAs. However, the diversity of atomic environments in the HEAs complicate the calculation of the H solution energy. With regard to this, we clarified an origin causing the variety of solution energy from the viewpoint of chemical and elastic interactions of H with the host atoms. Combining the semi-empirical atom potential and first-principles calculations regarding H in FeCrCoNi, NbMoTaW, and FeCuCrMnMo, we found that the elastic interaction presents a visibly linear relationship with the volume expansion caused by H insertion. By contrast, the chemical interaction shows a non-linear relationship with the volume of the interstitial polyhedron. A universal model was then established to generalize the solution energy of H. This model can expeditiously assess the H distribution and provide insight into evolution of the microstructure in HEAs.

Abstract
Abstract
Introduction
Traditionally Type- 1 myocardial infarction (T1-MI) results from a plaque erosion, rupture, or fissure. In contrast, Type- 2 myocardial infarction (T2-MI) is a consequence of severe supply and demand mismatch. Despite the different mechanisms, both T1-MI and T2-MI can be associated with severe morbidity and mortality. Yet there is sparse data analyzing in-hospital outcomes and readmission rates comparing patients who present with T1-MI and T2-MI.
Purpose
We aimed to compare the outcome data of patients with T1-MI and T2-MI derived from the Nationwide Readmissions Database, a large national database of hospital readmissions.
Method
We utilized the 2018 Nationwide Readmissions Database to identify all index hospital admissions with a primary diagnosis of “acute MI” (AMI) using ICD-10 diagnosis codes. All AMI admissions were further categorized into ST-elevation myocardial infarction (STEMI), no-ST-elevation myocardial infarction (NSTEMI), or T2-MI. Primary outcomes analyzed included 30-days major adverse cardiovascular events (MACE) (defined as re-infarction, repeat revascularization and death within 30 days of admission), short term mortality and readmission rates.
Results
Among 556,816 total admissions for AMI, 28,250 (5.1%) were T2-MI. Table 1 compares baseline variables and short-term outcomes for patients with T1-MI vs T2-MI. Compared to patients with T1-MI patients with T2-MI were older, more likely to be female, and had a higher burden of comorbidities. Additionally, T2-MI patients were less likely to receive coronary revascularization during the index admission. The mean length of stay for T2-MI patients was 4.7±0.6 days, which is longer than the length of stay for STEMI patient (4.1±0.4 days) but slightly shorter than NSTEMI patient (4.9±0.4 days). T2-MI patients had a higher rate of all-cause 30-days readmissions but a lower rate of 30-days MACE. Early mortality rate (within 30 days of index admission) in T2-MI patients was comparable to NSTEMI patients but was lower than STEMI patients. Cox proportional-hazards model adjusting for age, sex, comorbidities and type of hospital setting demonstrated that T2-MI was associated with a lower 30-day MACE risk (T2-MI vs STEMI: [HR 0.33 (95% CI 0.31–0.36)]; T2-MI vs NSTEMI [HR 0.70 (95% CI 0.64–0.75)]) and a lower risk of early mortality (T2-MI vs STEMI: [HR 0.29 (95% CI 0.26–0.32)]; T2-MI vs NSTEMI [HR 0.71 (95% CI 0.65–0.79)]). The adjusted HR for 30-days all-cause readmissions was higher with T2-MI, (T2-MI vs STEMI: [HR 1.16 (95% CI 1.10–1.23)]; T2-MI vs NSTEMI: [HR 1.11 (95% CI 1.06–1.16)]).
Conclusion
T2-MI patients are older and have a higher burden of comorbidities. After adjusting for baseline comorbidities, all-cause readmission risk is higher in T2-MI but short-term MACE and mortality is lower with T2-MI.

Abstract
Objective: To explore the incidence and age distribution of fundus abnormalities in pediatric patients aged 0-3 years in northwest China. Methods: A retrospective study of the clinical data of 8808 pediatric patients aged 0-3 years who underwent fundus examination with a wide-filed digital retinal imaging system and an indirect ophthalmoscope in our hospital from January 2008 to December 2019 were performed. There were 5092 males and 3716 females, with a median age of 1 month (range, 3 days to 3 years), a mean gestational age of 34.32 (SD 2.92) weeks (range, 24 to 42 weeks) and a mean birth weight of 2006.92 (SD 709.23) g (range, 490 to 5500 g), from Shaanxi Province (7415 cases, 84.18%), Gansu Province (770 cases, 8.74%), Ningxia Hui Autonomous Region (94 cases, 1.07%), Qinghai Province (53 cases, 0.60%), Xinjiang Uygur Autonomous Region (14 cases, 0.16%) and other neighboring areas (462 cases, 5.25%). The fundus condition of the enrolled pediatric patients was documented to calculate the annual detection rate. The joinpoint regression model was drawn to estimate the annual percent change and average annual percent change. The constituent ratios and age distribution of different types of fundus abnormalities were finally analyzed. Results: Fundus abnormalities were detected in 2 531 cases (28.74%). During the 12 years, the number of pediatric patients undergoing fundus examination each year in our center increased rapidly in the first 7 years, and then kept almost stable, while the number of fundus abnormality cases increased year by year. The positive detection rate showed an overall upward trend with an average annual percent change of +7.2%, and it was +30.09% from 2016 to 2019. Among all the pediatric patients with fundus abnormalities, there were 1 678 cases with developmental diseases (66.30%), 232 cases with hereditary diseases (9.16%), 140 cases with ocular tumor (5.53%), 64 cases with ophthalmic manifestations of systemic diseases (2.53%), 31 cases with ocular trauma (1.23%), 12 cases with infectious diseases or inflammation (0.48%) and 438 cases with other ocular abnormalities (17.31%). The top 5 abnormalities were retinopathy of prematurity (ROP; 1477 cases, 58.36%), gray patchy retinopathy (225 cases, 8.89%), retinal hemorrhage (157 cases, 6.20%), retinoblastoma (137 cases, 5.41%) and familial exudative vitreoretinopathy (77 cases, 3.04%). Fundus abnormalities varied with age. ROP, developmental diseases other than ROP, hereditary diseases, ocular trauma and infectious diseases were mostly detected in pediatric patients at 0-6 months old, while tumors were mostly detected after 1 year old. Conclusions: The detection rate of fundus abnormalities in the Department of Ophthalmology of Xijing Hospital of Air Force Medical University, a tertiary referral center in northwest China, increased notably year by year. The abnormalities were mainly developmental and hereditary lesions as well as of certain age distribution. They occurred with the highest frequency between birth and 6 months of age, in which ROP was in the ascendancy. Meanwhile, the detection rate of other developmental, hereditary and neoplastic disorders increased with age. Therefore, a comprehensive and objective understanding of the fundus disease in infants is essential. (Chin J Ophthalmol, 2021, 57: 777-783).

Abstract
Abstract
Introduction
Valvular heart disease (VHD) has been commonly described as the forgotten epidemic, with an estimated global prevalence of 2.5%. Current heart valve replacement therapies only partially offer a solution to the problem. In recent years, synthetic polymers have been explored due to their diversity allowing tailor-picking of essential traits, such as chemical properties, physical properties, and degradation states. This project investigated the feasibility and mechanical properties of reverse three-dimensional printing of biodegradable scaffolds for heart valve regeneration.
Method
Aortic valve dimensions at an average of 100mmHg were used for the computer aided design of the valves. Aortic valve scaffolds were fabricated using the 3D-TIPs reverse printing technique. Infill densities of 30%, 40% or 50% were used. Printed polymer scaffolds were coated in gelatine solution and compared using static tensile tests. Static strength and elasticity of coated and uncoated valves were compared.
Results
At 25%, 50% and 100% strain, significantly different elastic properties in favour of coated scaffolds between coated and uncoated valves was observed. Coated valves displayed greater strength than uncoated valves (p > 0.05). Computer aided design (CAD) software designed anatomically accurate scaffolds, but poor polymer coagulation was observed on the valve cusps.
Conclusions
The reverse-printing 3D-TIPS procedure successfully produces heart valve scaffolds which present architectural similarities to the naïve mitral valve, however, dimensions of the valves ought to be reassessed. Gelatine-coated valves exhibit greater elastic and tensile properties. A further understanding of cellular interactions on the polymer scaffold, in particular in vivo studies, are required for the continuity of future study.

Abstract
Abstract
Aim
Prosthetic heart valve replacement remains the gold standard treatment for valvular heart disease. However, its durability is limited and there is thus a need to develop an understanding of the feasibility of alternative replacement therapies. 3-dimensional printing of heart valves has been explored due to its patient-specific design and control of desired biomechanical properties. Computational studies of the synthetic valves will contribute to optimisation of designs, as well as improved understanding of the biomechanical behaviour of the complex structures.
Method
Aortic valve dimensions at an average of 100mmHg were used for the computerised design of the valves. Fine Element Analysis modelling generated computational experiments alongside predicted results. Simulated radial pressures tests were conducted at pressures from 0mmHg to 140mmHg and compression tests were conducted at displacement levels between 0-10mm. A Young’s modulus of 0.5 MPa was used. All simulations were conducted in a quasi-static manner.
Results
As the radial pressure on the valves increased, the Mises stresses increased. The maxium Mises stress of the heart valve was 0.09MPa and 0.13MPa under the pressures of 90mmHg and 140mmHg respectively. As valve displacement increased, the Mises stress of the heart valves proportionally rose. In simulated radial pressures tests, the compressive force was 0.19N at 1mm compressive displacment and 1.8N at 10mm compressive displacment.
Conclusions
The simulations demonstrated that 3D-printed heart valve scaffolds can withstand simulated radial pressure and compression tests. A further mechanical tests of the printed scaffold and understanding of its response to hemodynamic dynamic flow is required for the continuity of further study.
