Abstract
Tetragonal tungsten bronze (TTB) based oxides constitute a large family of dielectric materials which are known to exhibit complex distortions producing incommensurately modulated superstructures as well as significant local deviations from their average symmetry. The local deviations produce diffuse scattering in diffraction experiments. The structure as well as the charge dynamics of these materials are anticipated to be sensitive to defects, such as cation or oxygen vacancies. In this work, in an effort to understand how the structural and charge dynamical properties respond to these two types of vacancy defects, we have performed measurements of dielectric susceptibilities and single crystal diffraction experiments of two types of TTB materials with both 'filled' (Ba2NdFeNb4O15and Ba2PrFeNb4O15) and 'unfilled' (Sr0.5Ba0.5Nb2O6) cation sublattices. We also perform these measurements before and after oxygen annealing, which alters the oxygen vacancy concentrations. Surprisingly, we find that many of the diffuse scattering features that are present in the unfilled structure are also present in the filled structure, suggesting that the random fields and disorder that are characteristic of the unfilled structure are not responsible for many of the local structural features that are reflected in the diffuse scattering. Oxygen annealing clearly affected both color and dielectric properties, consistent with a diminishment of the oxygen vacancy concentration, but had little effect on observed diffuse patterns.

Abstract
BACKGROUND As a ubiquitous acid-regulating protein family in eukaryotes, general regulatory factors (GRFs) are active in various life activities of plants. However, detailed investigations of the GRFs gene family in moso bamboo are scarce. METHODS AND RESULTS Genome-wide characteristics of the GRF gene family in moso bamboo were analyzed using the moso bamboo genome. GRF phylogeny, gene structure, conserved domains, cis-element promoters, and gene expression were systematically analyzed. A total of 20 GRF gene family members were identified in the moso bamboo genome. These genes were divided into ε and non-ε groups. qRT-PCR (real-time quantitative reverse transcription polymerase chain reaction) showed that PheGRF genes responded to auxin and gibberellin treatment. To further study PheGRF gene functions, a yeast two-hybrid experiment was performed and verified by a bimolecular fluorescence complementation experiment. The results showed that PheGRF4e could interact with PheIAA30 (auxin/indole-3-acetic acid, an Aux/IAA family gene), and both were found to act mainly on the root tip meristem and vascular bundle cells of developing shoots by in situ hybridization assay. CONCLUSIONS This study revealed that PheGRF genes were involved in hormone response during moso bamboo shoot development, and the possible regulatory functions of PheGRF genes were enriched by the fact that PheGRF4e initiated auxin signaling by binding to PheIAA30.

Abstract
Background The status of children’s early motor skills play an important role during childhood and across lifetime. This study described FMS proficiency among boys (n = 189) and girls (n = 179) kindergarten children from 3 to 6 years old (4.4 s 0.7, mean ± SD) in northwest China. The differences in FMS proficiency of boys and girls from different environments, ethnic groups were analyzed respectively. Methods TGMD-3 was used to assess FMS. FMS mastery level was defined according to the correct performance of all criteria over two trials. The correlation between BMI and FMS and the interaction of environmental and ethnic on FMS were analyzed. The general linear model was used to evaluate the differences of boys and girls among environment groups (urban/suburban/county), and ethnic groups (Han/Hui/Tibetan) on the FMS subsets respectively. Results FMS proficiency was assessed in 368 3- to 6-year-old children (n = 156 urban, n = 101 suburban, n = 111 county)/(n = 208 Han, n = 107 Hui, n = 53 Tibetan). Overall, the highest skill performance was the run, with 86% achieving mastery level, and the poorest performance was the FH strike, at only 19%. Correlation between BMI and FMS is minimal. According to TGMD-3 scores, there was no significant difference between boys and girls in total FMS (p = 0.38). In terms of locomotor skills, boys performed better than girls in the hop, skip and slide (p < 0.05). County children performed significantly difference than urban and suburban children. Some skills performed less proficiently, (boys in 6 of 13 skills: run, HJ, slide, TH strike, FH strike and kick; girls in 4 of 13 skills: run, slide, TH strike and kick) and some skills performed more proficiently (boys in dribble; girls in hop and dribble). Tibetan children performed significantly difference than Han and Hui children. Some skills performed less proficiently, (boys in 6 of 13 skills: run, HJ, slide, TH strike, FH strike and kick; girls in TH strike) and some skills performed more proficiently (boys and girls were all in dribble). Conclusion Children in northwest China showed certain characteristics in FMS, the county/Tibetan boys and girls performed poorer than others in ability to execute particular process characteristics of some skills and performed more outstanding in other skills. It suggests that a certain group population may need specific focus on interventions to improve their FMS level.

Abstract
BackgroundJuvenile idiopathic arthritis (JIA) is the most common rheumatic condition among children and teens1 and contributes to a diminished quality of life.2 Previous data underscore the potential for abatacept to improve health-related outcomes in patients with JIA after demonstrating poor responses to other DMARDs.3 Patients with RA show greater persistence on abatacept vs TNF inhibitors (TNFi), and this should also be confirmed in patients with JIA.4ObjectivesTo evaluate treatment persistence and adherence at 12- and 18-month follow-up in patients with JIA newly initiating either abatacept or a TNFi.MethodsThis analysis used data from the IQVIA PharMetrics Plus claims database from Jan 2008–Apr 2021. We identified patients with ≥ 1 claim of JIA diagnosis after Jan 2008, who were < 18 years old at initial diagnosis, had ≥ 1 claim of abatacept or TNFi treatment (adalimumab, etanercept, golimumab) following diagnosis, had continuous enrollment in medical and pharmacy benefits for ≥ 12 months before index date (first prescription of abatacept or TNFi), and had 12 or 18 months’ continuous medical and pharmacy enrollment after index date. Patients receiving abatacept or TNFi treatment ≤ 12 months prior to index date and patients initiating combined abatacept + TNFi treatment on the index date were excluded. Specific outcomes included: discontinuation (absence of a new prescription for index treatment within the gap of 5× treatment half-life), persistence rate (proportion of patients continuing index medication without any gaps exceeding 5× treatment half-life), and treatment adherence (defined as medication possession ratio [MPR, proportion of follow-up period where medication supply is available] and proportion of days covered [PDC, proportion of follow-up period where a patient is covered by a given drug]). All outcomes were reported at 12 and 18 months. All statistical analyses are descriptive with the intent for hypothesis generation.ResultsThere were 2847 patients (abatacept, n = 111; TNFi, n = 2736) at 12-month follow-up; fewer completed the 18-month follow-up (2403 patients: abatacept, n = 94; TNFi, n = 2309). At index date, treatment groups were similar for sex, geographic location, and comorbidities (Table 1). Numerically higher persistence was observed in patients prescribed abatacept compared with TNFi overall at both time points. Abatacept persistence was higher than etanercept but similar to adalimumab (Figure 1). At 12 months, the percent of patients with PDC ≥ 0.8 was 57% for abatacept, 51% for adalimumab, and 38% for etanercept, while MPR ≥ 0.8 was 63% for abatacept, 55% for adalimumab, and 42% for etanercept. Patients prescribed abatacept had numerically greater proportions of PDC ≥ 0.8 (abatacept, 48%; adalimumab, 40%; etanercept, 29%) and MPR ≥ 0.8 (abatacept, 53%; adalimumab, 44%; etanercept, 33%) at 18 months.Table 1.Baseline characteristics of patients with 12-month follow-up dataCharacteristicAbatacept (n = 111)TNFi (n = 2736)Age, years, mean (SD)14.4 (3.8)12.6 (4.6)Female sex89 (80.2)1930 (70.5)Geographic region South43 (38.7)865 (31.6) Midwest40 (36.0)818 (29.9) West9 (8.1)408 (14.9) East19 (17.1)540 (19.7) Unknown0 (0)105 (3.8)Comorbidities Asthma9 (8.1)275 (10.1) COPD11 (9.9)323 (11.8) Cardiovascular disease14 (12.6)222 (8.1) Uveitis14 (12.6)321 (11.7) Iridocyclitisa12 (10.8)216 (7.9)CCI score, mean (SD)0.58 (0.73)0.46 (0.68)Data are shown as n (%) unless otherwise specified.aSubgroup disease under uveitis.CCI, Charlson Comorbidity Index; COPD, chronic obstructive pulmonary disease.ConclusionThe present findings suggest that patients with JIA initiating abatacept treatment display numerically higher persistence and adherence compared with patients treated with TNFis at both 12- and 18-months’ follow-up.References[1]Prakken B, et al.

Abstract
Objectives: To understand the awareness rate and its influencing factors of their HBV infection status among HBsAg-positive persons aged 15-69 years in China. Methods: A cross-sectional design was used to conduct a questionnaire survey on the awareness of their infection status among HBsAg-positive persons aged 15-69 years who were identified in the 2020 national hepatitis B seroepidemiology survey. The awareness rate of the whole respondent and respondents with different characteristics were described, and the differences were compared with the χ2 test. The logistic regression model was used to analyze the factors influencing the awareness rate. Results: The overall awareness rate among the respondents was 43.10% (1 828/4 241). The awareness rate was lower in males than in females (41.30% vs. 44.65%). The awareness rate was lower in the 60-69-years-old age group than in other age groups (30.38% vs. 36.77%-57.58%). The awareness rate was lower in rural areas than in urban areas (39.43% vs. 47.32%). The awareness rate was lower in regions with a per capita gross domestic product (GDP) below RMB 54 000 than in regions with a per capita GDP of RMB 54 000 and above (36.81% vs. 41.61%-50.30%). The awareness rate was lower in respondents without other liver diseases than with other liver diseases (41.52% vs. 60.68%). The awareness rate was lower in respondents without a family history of hepatitis B-related disease or unknown family history than with a family history (43.58% vs. 68.26%; 24.71% vs. 68.26%). Multivariate logistic regression analysis showed that male [odds ratio (OR)=0.841, 95% confidence interval (CI): 0.734-0.964], high school and below [primary school and below, junior middle school, high school/technical secondary school, OR (95%CI): 0.247 (0.190-0.321), 0.451 (0.352-0.577), 0.634 (0.486-0.827)], rural areas (OR=0.822, 95%CI: 0.715-0.945) and regions with a per capita GDP below RMB 80 000 [54 000-80 000, OR (95%CI): 0.810 (0.688-0.954), below RMB 54 000, OR (95%CI): 0.793 (0.669-0.941)] were the negative factors influencing the awareness rate. While 30-39-years-old (OR=2.089, 95%CI: 1.626-2.683) and 40-49-years-old (OR=1.590, 95%CI: 1.250-2.023) age groups, with other liver diseases (OR=2.244, 95%CI: 1.754-2.871) and family history related to hepatitis B (OR=2.688, 95%CI: 2.242-3.223) were the positive factors influencing the awareness rate. Conclusion: The overall awareness rate of their infection status among HBsAg-positive persons aged 15-69 years is 43.10% in China. Health promotion and coverage expansion on HBV screening should be further strengthened to achieve the proposed World Health Organization's target of 90% HBV infection diagnosis rate by 2030.

Auxin plays a crucial regulatory role in higher plants, but systematic studies on the location of auxin local biosynthesis are rare in bamboo and other graminaceous plants. We studied moso bamboo (Phyllostachys edulis), which can grow up to 1 m/day and serves as a reference species for bamboo and other fast-growing species. We selected young tissues such as root tips, shoot tips, young culm sheaths, sheath blades, and internode divisions for local auxin biosynthesis site analysis. IAA immunofluorescence localization revealed that auxin was similarly distributed in different stages of 50-cm and 300-cm bamboo shoots. Shoot tips had the highest auxin content, and it may be the main site of auxin biosynthesis in the early stage of rapid growth. A total of 22 key genes in the YUCCA family for auxin biosynthesis were identified by genome-wide identification, and these had obvious tissue-specific and spatio-temporal expression patterns. In situ hybridization analysis revealed that the localization of YUCCA genes was highly consistent with the distribution of auxin. Six major auxin synthesis genes, PheYUC3-1, PheYUC6-1, PheYUC6-3, PheYUC9-1, PheYUC9-2, and PheYUC7-3, were obtained that may have regulatory roles in auxin accumulation during moso bamboo growth. Culm sheaths were found to serve as the main local sites of auxin biosynthesis and the auxin required for internode elongation may be achieved mainly by auxin transport.

Abstract
Methacryloyloxydecyl dihydrogen phosphate (MDP) has been speculated to induce mineralization, but there has been no convincing evidence of its ability to induce intrafibrillar mineralization. Polymers play a critical role in biomimetic mineralization as stabilizers/inducers of amorphous precursors. Hence, MDP-induced biomimetic mineralization without polymer additives has not been fully verified or elucidated. By combining 3-dimensional stochastic optical reconstruction microscopy, surface zeta potentials, contact angle measurements, inductively coupled plasma-optical emission spectroscopy, transmission electron microscopy, atomic force microscopy, and Fourier transform infrared spectroscopy with circular dichroism, we show that amphiphilic MDP can not only demineralize dentin by releasing protons as an acidic functional monomer but also infiltrate collagen fibrils (including dentin collagen), unwind the triple helical structure by breaking hydrogen bonds, and finally immobilize within collagen. MDP-bound collagen functions as a huge collagenous phosphoprotein (HCPP), in contrast to chemical phosphorylation modifications. HCPP can induce biomimetic mineralization itself without polymer additives by alternatively attracting calcium and phosphate through electrostatic attraction. Therefore, we herein propose the dual functions of amphiphilic MDP monomer with de- and remineralizing ability. MDP in the free state can demineralize dentin substrates by releasing protons, whereas MDP in the collagen-bound state as HCPP can induce intrafibrillar mineralization. The dual functions of MDP monomer with de- and remineralization properties might create a new epoch in adhesive dentistry and preventive dentistry.

Abstract
OBJECTIVE Ciprofol is a newly developed intravenous sedative-hypnotic drug. The objective of the study was to prove whether ciprofol was non-inferior to propofol for the successful induction of general anesthesia. The ideal post-induction sedation level was assessed by comparing patients' clinical symptoms and their hemodynamic effects in responding to noxious stimuli, mostly tracheal intubation and bispectral index (BIS) alterations following ciprofol/propofol administration. PATIENTS AND METHODS In this multi-center, randomized, double-blind phase 3 trial, selective surgery patients were randomly assigned in a 1:1 ratio to either ciprofol 0.4 mg/kg (n = 88) or propofol 2.0 mg/kg (n = 88) groups. The primary endpoint was the percentage of patients with successful anesthesia inductions. Secondary endpoints included the times to successful induction of general anesthesia and loss of the eyelash reflex, changes in BIS, as well as safety indicators. RESULTS The anesthesia induction success rates for both ciprofol 0.4 mg/kg and propofol 2 mg/kg groups were 100.0%, with a 95% CI lower success limit of -4.18% difference between the two groups, indicating that ciprofol was non-inferior to propofol. For secondary outcomes, the average time to successful anesthesia and loss of the eyelash reflex were 0.91 min and 0.80 min for ciprofol and 0.80 min and 0.71 min for propofol, respectively. The pattern of BIS changes with ciprofol was similar to propofol and stable during the anesthesia maintenance period. Safety was comparable with 88.6% TEAEs in the ciprofol group compared to 95.5% in the propofol group. The incidence of injection pain was significantly lower in the ciprofol group compared to the propofol group (6.8% vs. 20.5%, p < 0.05). In addition, the patients treated with ciprofol had a lesser increase in blood pressure and heart rate, and fewer cases with BIS > 60 within 15 min of intravenous administration, which indicated that ciprofol may provide a better ideal sedation level during the post-induction period under an equivalent dosing regimen to propofol. CONCLUSIONS Ciprofol for patients undergoing selective surgery is a new option for the induction of general anesthesia.

Abstract
Dentin is a major mineralized component of teeth. Odontoblasts are responsible for synthesis and secretion of dentin matrix. Previously, it has been demonstrated in a cell culture system that the E3 ubiquitin ligase, murine double minute 2 (Mdm2), promotes odontoblast-like differentiation of mouse dental papilla cells (mDPCs) by ubiquitinating p53 and the odontoblast-specific substrate Dlx3. However, whether Mdm2 plays an essential role in vivo in odontoblast differentiation and dentin formation remains unknown. In this study, we investigated the in vivo functions of Mdm2 using Dmp1-Cre;Mdm2 flox/flox mice combined with multiple histological and molecular biological methods. The results showed that Mdm2 deletion in the odontoblast layer led to defects in odontoblast differentiation and dentin formation. Unexpectedly, specific inhibition of the Mdm2-p53 axis in wild-type mice by injection of a small-molecule inhibitor Nutlin-3a indicated that the role of Mdm2 in dentinogenesis was p53 independent, which was inconsistent with the previous in vitro study. In situ proximity ligation assay (PLA) showed that Mdm2 interacted with and ubiquitinated Dlx3 in the odontoblast nucleus of mouse molars. Dlx3 promoted the translocation of Mdm2 to the nucleus, and in turn, the nuclear Mdm2 mediated ubiquitination of Dlx3 and promoted the odontoblast-like differentiation of mDPCs. Dlx3 interacted with Mdm2 through its C-terminal domain. Deletion of the C-terminal domain of Dlx3 reversed the enhanced odontoblast-like differentiation and the activation of Dspp promoter mediated by overexpression of wild-type or nuclear Mdm2. Our findings suggest that nuclear Mdm2 mediates ubiquitination of the transcription factor Dlx3, which is essential for Dlx3 transcriptional activity on Dspp as well as subsequent odontoblast differentiation and dentin formation.

Abstract
OBJECTIVE To investigate the role of miRNAs in amniotic fluid exosomes in growth and development of fetuses with Down syndrome (DS). METHODS Amniotic fluid were collected from 20 fetuses with DS and 20 normal fetuses (control) to extract amniotic exosome miRNA. MicroRNA sequencing technique was used to identify the differentially expressed miRNAs between the two groups, for which gene ontology (GO) and pathway analysis was performed. Three differentially expressed miRNAs with the strongest correlation with DS phenotype were selected for qPCR verification. Dual luciferase reporter assay was used to verify the activity of let-7d-5p for targeted regulation of BACH1. RESULTS We identified 15 differentially expressed miRNAs in DS as compared with the control group, among which 7 miRNAs were up-regulated and 8 were down-regulated. Target gene prediction results showed that the differentially expressed miRNAs targeted 17 DS-related genes. GO analysis revealed that the main functions of the target genes involved protein binding, protein transport, ATP binding, transferase activity and synapses. Pathway analysis revealed that the functional pathways were closely related with the development of the nervous system. qPCR results showed that the expression levels of miR-140-3p and let-7d-5p were significantly lower in DS group than in the control group (P < 0.05), as was consistent with miRNA sequencing results; the expression level of miR-4512 was significantly higher in DS group than in control group (P < 0.05), which was contrary to miRNA sequencing results. The results of double luciferase reporter gene assay confirmed that let-7d-5p was capable of targeted regulation of BACH1 expression. CONCLUSION Let-7d-5p in amniotic fluid exosomes may promote oxidative stress events in the brain of fetuses with DS by regulating BACH1 expression.

Abstract
OBJECTIVE To evaluate the efficacy and safety of HSK3486 for the induction and maintenance of general anesthesia in elective surgical patients, but excluding emergency, cardiothoracic, cerebral and endoscopic sinus cases. PATIENTS AND METHODS A total of 40 eligible patients were randomly assigned to HSK3486 (n = 30) or propofol (n = 10) dosage groups in a ratio of 3:1. Drugs were administered as a bolus injection of 0.4 mg/kg (HSK3486) or 2.0 mg/kg (propofol) for induction, followed by maintenance infusion with the same anesthetic. An additional 6 non-randomized patients received propofol (2.0 mg/kg) for induction and were given HSK3486 for maintenance. RESULTS The primary efficacy endpoint - the success rate of anesthesia maintenance - was 100% in the 3 arms. The secondary efficacy endpoints included times from discontinuation of HSK3486 or propofol maintenance to full alertness, respiratory recovery, extubation and reaching the goal of the Aldrete score. Also, the proportion of patients who constantly maintained BIS40-60 or those with a period of BIS40-60 during maintenance anesthesia showed no significant difference in the HSK3486 and propofol groups (all p > 0.05). Patients who received HSK3486 exhibited a higher satisfaction score from anesthesiologists during the induction period (p = 0.024). The occurrence and types of treatment-emergent adverse events were similar among the 3 arms, both with a severity of grade 1 or 2. Drug-related hypotension occurred in 14 (46.7%) and 7 (70.0%) patients treated with HSK3486 and propofol, respectively. CONCLUSIONS HSK3486 exhibited good efficacy for the induction and maintenance of general anesthesia and was well tolerated by patients who underwent elective surgery.

Abstract
Objective: To study the effects on extravascular lung water of lung protective ventilation strategy applying on piglets with acute respiratory distress syndrome (ARDS) induced by paraquat (PQ) under pulse indicating continuous cardiac output (PiCCO) monitoring. Methods: The piglets models with ARDS induced by PQ were established in June 2020 and all of them were received mechanical ventilation and divided into three groups according to tidal volume (V(T)) : small V(T) group (6 ml/kg) , middle V(T) group (10 ml/kg) and large V(T) group (15 ml/kg) , there were 5 piglets in each group. The positive end expiratory pressure (PEEP) were all setup on 10 cmH(2)O. The indexes such as arterial blood gas analysis, oxygenation index (OI) , extravascular lung water index (ELWI) and pulmonary vascular permeability index (PVPI) were monitored at time of before the model was established (baseline) , time of the model was established (t(0)) and 2 h (t(2)) , 4 h (t(4)) , 6 h (t(6)) after mechanical ventilation. Lung tissue were punctured at time of baseline, t(0) and t(6) to be stained by Hematoxylin-eosin (HE) staining and pulmonary pathology were observed under light microscopy. Results: The heart rate (HR) , mean arterial pressure (MAP) and partial pressure of carbon dioxide (PaCO(2)) of all groups were higher than the base value while the pH values, partial pressure of oxygen (PaO(2)) and OI were lower than the base value when the models were established (P<0.05) . After mechanical ventilation, the HR and MAP values of all groups at t(2), t(4) and t(6) were lower than t(0) while the PaCO(2) of t(4) and t(6) were all higher than t(0), the differences were statistically significant (P<0.05) . The PaO(2) and OI of all groups showed a trend of rising at first and then decreasing after mechanical ventilation. The MAP, PaO(2), PaCO(2) and OI of the middle V(T) group and large V(T) group were apparently lower than that of the small V(T) group at t(2), t(4) and t(6) (P<0.05) . The ELWI and PVPI at t(0) of all groups were higher than that of baseline (P<0.05) . The ELWI of the small V(T) group at t(6) were lower than t(0) of the same group and t(6) of the middle V(T) group and large V(T) group (P<0.05) . HE staining showed congestion and edema of alveolar tissue, swelling of capillaries, exudation of red blood cells and widening of alveolar septum in piglets after successful modeling. And further widening of alveolar septum and rupture of alveolar septum could be seen in the lung tissues of each group at t(6), and the injury was the slightest in the small V(T) group. Conclusion: The lung protective ventilation strategy can alleviate the extravascular lung water and ARDS induced by PQ and improve oxygenation.

Abstract
Alginate hydrogels are gaining traction for use in drug delivery, regenerative medicine, and as tissue engineered scaffolds due to their physiological gelation conditions, high tissue biocompatibility, and wide chemical versatility. Traditionally, alginate is decorated at the carboxyl group to carry drug payloads, peptides, or proteins. While low degrees of substitution do not cause noticeable mechanical changes, high degrees of substitution can cause significant losses to alginate properties including complete loss of calcium cross-linking. While most modifications used to decorate alginate deplete the carboxyl groups, we propose that alginate modifications that replenish the carboxyl groups could overcome the loss in gel integrity and mechanics. In this report, we demonstrate that restoring carboxyl groups during functionalization maintains calcium cross-links as well as hydrogel shear-thinning and self-healing properties. In addition, we demonstrate that alginate hydrogels modified to a high degree with azide modifications that restore the carboxyl groups have improved tissue retention at intramuscular injection sites and capture blood-circulating cyclooctynes better than alginate hydrogels modified with azide modifications that deplete the carboxyl groups. Taken together, alginate modifications that restore carboxyl groups could significantly improve alginate hydrogel mechanics for clinical applications. STATEMENT OF SIGNIFICANCE: Chemical modification of hydrogels provides a powerful tool to regulate cellular adhesion, immune response, and biocompatibility with local tissues. Alginate, due to its biocompatibility and easy chemical modification, is being explored for tissue engineering and drug delivery. Unfortunately, modifying alginate to a high degree of substitution consumes carboxyl group, which are necessary for ionic gelation, leading to poor hydrogel crosslinking. We introduce alginate modifications that restore the alginate's carboxyl groups. We demonstrate that modifications that reintroduce carboxyl groups restore gelation and improve gel mechanics and tissue retention. In addition to contributing to a basic science understanding of hydrogel properties, we anticipate our approach will be useful to create tissue engineered scaffolds and drug delivery platforms.

Abstract
Objective: This study analyzed the correlation between genetic mutation and prognostic significance in childhood acute lymphoblastic leukemia (ALL) . Methods: Targeted exome by next-generation sequencing (NGS) technology was used to carry out molecular profiling of untreated 141 children with ALL in Fujian Medical University Union Hospital from November 2016 to December 2019. Correlation of genetic features and clinical features and outcomes was analyzed. Results: Among the 141 pediatric patients with ALL, 160 somatic mutations were detected in 83 patients (58.9% ) , including 37 grade Ⅰ mutations and 123 grade Ⅱ mutations. Single nucleotide variation was the most common type of mutation. KRAS was the most common mutant gene (12.5% ) , followed by NOTCH1 (11.9% ) , and NRAS (10.6% ) . RAS pathway (KRAS, FLT3, PTPN11) , PAX5 and TP53 mutations were only detected, and NRAS mutations was mainly found in B-ALL while FBXW7 and PTEN mutations were only found, and NOTCH1 mutation was mainly detected in T-ALL. The average number of mutations detected in each child with T-ALL was significantly higher than in children with B-ALL (4.16±1.33 vs 2.04±0.92, P=0.004) . The children were divided into mutation and non-mutation groups according to the presence or absence of genetic variation. There were no statistically significant differences in sex, age, newly diagnosed white blood cell count, minimal or measurable residual disease monitoring results, expected 3-year event-free survival (EFS) and overall survival (OS) between the two groups (P>0.05) . On the other hand, the proportion of T-ALL and fusion gene negative children in the mutant group was significantly higher than the non-mutation group (P=0.021 and 0.000, respectively) . Among the patients without fusion gene, the EFS of children with grade I mutation was significantly lower than children without grade I mutation (85.5% vs 100.0% , P=0.039) . Among children with B-ALL, the EFS of those with TP53 mutation was significantly lower than those without TP53 mutation (37.5% vs 91.2% , P<0.001) . Conclusion: Genetic variation is more common in childhood ALL and has a certain correlation with clinical phenotype and prognosis. Therefore, targeted exome by NGS can be used as an important supplement to the traditional morphology, immunology, cytogenetics, and molecular biology classification.

Abstract
BACKGROUND Mechanical ventilation (MV) is an important lifesaving method in intensive care unit (ICU). Prolonged MV is associated with ventilator associated pneumonia (VAP) and other complications. However, premature weaning from MV may lead to higher risk of reintubation or mortality. Therefore, timely and safe weaning from MV is important. In addition, identification of the right patient and performing a suitable weaning process is necessary. Although several guidelines about weaning have been reported, compliance with these guidelines is unknown. Therefore, the aim of this study is to explore the variation of weaning in China, associations between initial MV reason and clinical outcomes, and factors associated with weaning strategies using a multicenter cohort. METHODS This multicenter retrospective cohort study will be conducted at 17 adult ICUs in China, that included patients who were admitted in this 17 ICUs between October 2020 and February 2021. Patients under 18 years of age and patients without the possibility for weaning will be excluded. The questionnaire information will be registered by a specific clinician in each center who has been evaluated and qualified to carry out the study. DISCUSSION In a previous observational study of weaning in 17 ICUs in China, weaning practices varies nationally. Therefore, a multicenter retrospective cohort study is necessary to be conducted to explore the present weaning methods used in China. TRIAL REGISTRATION Chinese Clinical Trial Registry (ChiCTR) (No. ChiCTR2100044634).

Abstract
PURPOSE OF THE STUDY To evaluate the therapeutic effects of small incision open reduction and internal fixation and arthroscopic high strength non-absorbable suture on tibial insertion avulsion fracture of the anterior cruciate ligament (ACL). MATERIAL AND METHODS In this prospectively study, 72 patients with ACL tibial insertion avulsion fracture treated from December 2017 to June 2020 were enrolled and divided into group A (treated with small incision open reduction and cannulated screw internal fixation) and group B (treated with arthroscopic high strength non-absorbable suture) using a random number table (n=36). Their general data, surgical indices and incidence of postoperative adverse reactions were compared. Knee function indices were compared before and after treatment, and evaluated by random walk model. RESULTS No significant differences were found in the general data, intraoperative blood loss, preoperative Lysholm score, International Knee Documentation Committee (IKDC) score, Tegner score, knee range of motion and difference of bilateral tibial forward displacement distance, and total incidence rate of postoperative adverse reactions between the two groups (P>0.05). Group B had significantly longer operation time, and significantly shorter hospital stay, time of first ambulation after operation and bone healing time than group A (P<0.05). Both groups had improved Lysholm score, IKDC score, Tegner score and knee range of motion after treatment, especially in group B (P<0.05). The difference of bilateral tibial forward displacement distance significantly reduced in both groups after treatment, particularly in group B (P<0.05). The random walk model revealed that group B had better improvement of knee function than group A. CONCLUSIONS Arthroscopic high strength non-absorbable suture in the treatment of ACL tibial insertion avulsion fracture can dramatically improve the knee function indices of patients, with rapid recovery and high safety, so it has a broad prospect of clinical application. Key words: small incision open reduction and internal fixation, arthroscopic high strength non-absorbable suture, tibial insertion avulsion fracture, anterior cruciate ligament, random walk model.

Abstract
OBJECTIVE To assess the value of the purple sign for predicting long-term rebleeding events in cirrhotic patients following endoscopic selective varices devascularization. METHODS We retrospectively analyzed the clinical data of 97 patients with liver cirrhosis, who had a history of gastroesophageal variceal bleeding and underwent endoscopic selective varices devascularization. Thirty-two of the patients showed purple sign after endoscopic treatment. We used propensity score matching (PSM) to minimize the selection bias of the patients (purple sign vs no purple sign) and reduce the intergroup differences of clinical characteristics. The primary outcome measure of this study was cumulative rebleeding events after endoscopic selective varices devascularization. RESULTS The 1-year rebleeding rate (27.0% vs 36.7%) or 6-month rebleeding rate (10.9% vs 26.9%) following endoscopic treatment was not significantly different between the purple sign group and no purple sign group before PSM (P=0.2385). But after PSM, the 1-year rebleeding rate (28.2% vs 56.4%) and 6-month rebleeding rate (5.0% vs 37.0%) were significantly lower in the purple sign group than in the no purple sign group (P=0.0304). CONCLUSIONS The presence of purple sign indicates a lower risk of rebleeding after endoscopic treatment of cirrhotic gastroesophageal varices and a potentially favorable treatment response after endoscopic therapy, thus providing a clinical indicator for stratification of the patients for sequential endoscopic sessions.

Abstract
BACKGROUND Vulvovaginal candidiasis (VVC) is frequent in women of reproductive age, but very limited data are available on the epidemiology in cases of VVC in China. OBJECTIVES The current study has been conducted to reveal the prevalence, species distribution of yeast causing VVC and molecular genetics of Candida albicans in China. METHODS Vaginal swabs were collected from 543 VVC outpatients recruited in 12 hospitals in China between September 2017 and March 2018. They were preliminarily incubated on Sabouraud dextrose agar and then positive subjects of which were then transmitted to our institute for further identification. CHROMagar™ was used to isolate Candida species, and all isolates were finally identified by DNA sequencing. Multilocus sequence typing (MLST) was used to analyse phylogenetic relationships of the various C. albicans isolates. RESULTS Eleven different yeast species were identified in 543 isolates, among which C. albicans (84.7%) was the most frequent, followed by C. glabrata (8.7%). We obtained 117 unique diploid sequence types from 451 clinical C. albicans isolates and 92 isolates (20.4%) belonged to a New Clade. All the strains appearing in the New Clade were from northern China and they were isolated from non-recurrent VVC. CONCLUSIONS Our findings suggest that C. albicans are still the main cause of VVC in China and the majority of C. albicans isolates belongs to Clade 1 with DST 79 and DST 45 being two most common. Moreover, the New Clade revealed in our study seems to be specific to northern China.

Abstract
Objective: To analyze the incidence of HIV infection and identify associated risk factors in drug abusers among men who have sex with men (MSM) in Tianjin and Shanghai through a cohort study and provide a basis for HIV prevention in this population. Methods: A prospective cohort study was conducted among MSM who had a history of drug abuse in the past six months from June 2016 to June 2018 in the two cities. MSM were investigated to obtain information on sociodemographic characteristics, HIV-related sexual behaviors, and drug abuse. Follow-up investigation and HIV testing were carried out based on the baseline survey and testing. Cox regression analysis was conducted to identify the risk factors for HIV infection. Results: There were 455 eligible subjects, and 16 new HIV infection cases were identified in the 2-year follow-up survey. The cumulative follow-up time was 586.08 person-years, and the incidence of HIV infection was 2.73/100 person-years. The multivariate Cox regression analysis results showed that compared with those aged ≥25 years, consistent condom use during anal sex with men in the past six months, without mixed-use of drugs, these aged <25 years (HR=5.01, 95%CI: 1.09-23.11), inconsistent condom use during anal sex with men in the past six months (HR=1.58, 95%CI: 1.04-2.41) and mixed-use of drugs (HR=1.92, 95%CI: 1.08-3.40) were significantly associated with HIV infection in this cohort. Conclusions: The younger age, inconsistent condom use during anal sex with men, and mixed drug use appeared as risk factors of new HIV infection in drug abusers among MSM. HIV prevention and intervention in this population should be further strengthened.

Abstract
Objective: To investigate the feasibility and efficacy of mini-incision with endoscope-assisted resection for bilateral congenital second branchial cleft fistula, and to report on a rare pedigree. Methods: The clinical data of 5 patients with bilateral congenital second branchial fistula admitted in Fujian Provincial Hospital from April 2007 to December 2018 were retrospectively reviewed, including 2 males and 3 females, aged from 3 to 31 years old. The surgical strateges and clinical experience of single mini-incision with endoscope-assisted fistulectomy were summarized, and a rare pedigree was reported. Results: In five patients, Case 1 to Case 4 were treated with bilateral endoscopic-assisted fistula high ligation with titanium clips and removal through a single small incision under general anesthesia. No obvious complications occurred after the operation. The patients were followed up for 40-164 months with no fistula recurrence. Case 5 gave up surgical resection and was followed up for 24 months with acute infection attack once. Case 2 and Case 4 came from the same family. In this family, 7 out of 31 members of four generations had second branchial cleft fistulas, of which 4 were bilateral and 3 were right. Pedigree analysis was consistent with autosomal dominant inheritance. No deafness, preauricular tag, external and middle ear deformity and kidney malformation were found in the family members. Conclusions: Bilateral congenital second branchial cleft fistula is rare. Surgical resection is the preferred treatment. Mini-incision with endoscopic-assisted fistula high ligation with titanium clip and resection has clear operative field, ideal cosmetic effect and definite curative effect.

Abstract
Aberrations in oncogene RET (rearranged during transfection) have been found to be the cause of different kinds of malignancies, especially in lung and thyroid cancers. Targeted therapy of RET-altered cancers using multi-kinase inhibitors (MKIs) has demonstrated limited clinical efficacy due to off-target toxicity. In May 2020, the U.S. Food and Drug Administration (FDA) approved a novel specific RET inhibitor for use in some subtypes of lung and thyroid cancers with RET alterations. In this review, we summarize the mechanism of action, pharmaceutical properties and clinical data of selpercatinib, and share some of our perspectives.

Abstract
BACKGROUND AND PURPOSE Growth of subependymal giant cell tumor and subependymal nodules has not been well-characterized. The purpose of this study was to determine whether growth curves can differentiate subependymal giant cell tumors from subependymal nodules. MATERIALS AND METHODS Brain MR imaging of patients with tuberous sclerosis complex were retrospectively reviewed from 2002 to 2018. All lesions in the region of the foramen of Monro were measured. Lesions were categorized on the basis of maximal diameter at the most recent scan: small lesions (<1 cm), indeterminate lesions (>1 cm), and resected lesions (>1 cm and surgically resected). Growth velocity and acceleration on serial imaging were analyzed, and growth rates were calculated between 0 and 20 years of age and compared among the 3 categories. RESULTS Forty-one patients were analyzed. The average age at the earliest scan was 5.9 (SD = 5.7) years. One hundred twenty-six small, 27 indeterminate, and 10 resected lesions were measured. Subependymal giant cell tumors grew faster than indeterminate lesions between 6 and 15 years of age. Indeterminate lesions grew faster than small lesions at 0-10 years of age. Resected lesions showed increased velocity and acceleration of growth compared with indeterminate lesions and small lesions on serial imaging. CONCLUSIONS Growth differentiates subependymal nodules and subependymal giant cell tumors within the first 20 years of life, and the use of velocity and acceleration of growth may refine the diagnostic criteria of subependymal giant cell tumors. Additionally, 6-15 years of age may be an important period to monitor subependymal giant cell tumors at the foramen of Monro because increased growth may help to identify subependymal giant cell tumors that will continue to grow and result in obstructive hydrocephalus.

Abstract
Viral hepatitis has been causing big threat to public health globally. The number of annual deaths caused by hepatitis surpassed the deaths caused by AIDS, tuberculosis, and malaria. World Health Organization (WHO) issued the global health sector strategy on viral hepatitis 2016-2020 (GHSS) to control its epidemic. It established the Strategies and Technical Advisory Committee on HIV, viral hepatitis, and sexually transmitted infections (STAC). This paper summarizes the GHSS goals and the keynote of the 2020 STAC meeting, analyzes the challenges and opportunities faced by China in eliminating viral hepatitis, and provides the comments on the papers on this issue, which could guide further actions.

Abstract
Objective: To understand the characteristics of hepatitis B cases reported through the National Notifiable Disease Reported System (NNDRS) of China in 2019, analyze the quality of hepatitis B reporting. Methods: The survey forms and reporting cards of hepatitis B cases in 200 surveillance points in China in 2019 were collected from NNDRS, the completeness rate of the reporting card was calculated, and the reported hepatitis B cases were verified based on the diagnostic criteria (WS 299-2008). The clinical types of the cases after verification were compared with the reported ones, the consistency was evaluated with Kappa test. The reasons for the inconsistent clinical types of the cases were analyzed. Results: In 2019, a total of 64 686 hepatitis B cases were reported through NNDRS. Acute, chronic and unclassified hepatitis B cases accounted for 5.8%, 92.4% and 1.8%, respectively. The average age of reported cases was 47 (47±15) years, and males accounted for 64.4%. The average level of alanine aminotransferase was 214.2 (214.2±1 253.4) U/L. The reported cases mainly worked in agriculture, forestry, animal husbandry, fishery, and water conservancy (50.6%, 32 722). The proportions of cases reported from the eastern, western and central regions were 42.5% (27 501),22.1% (14 315) and 35.4% (22 870), respectively. The consistent rate of the clinical types between the reported cases and the verified cases was 58.8%, with a Kappa value of 0.15. For the 39 271 cases confirmed as acute and chronic hepatitis B cases in the reporting cards, the consistent rate of the clinical types between the reported cases and the verified cases was 96.9%, with a Kappa value of 0.73. In 94.5% (24 267/25 681) of the cases with inconsistent clinical types, the reporting card information were incomplete. Conclusion: The diagnosis of hepatitis B has been improved in the hepatitis B surveillance in China, but it is necessary to improve the completeness of the reporting cards of hepatitis B cases to NNDRS.

Abstract
Objective: To make a cost-benefit analysis of the hepatitis B vaccination (HepB) to prevent mother-to-child transmission (PMTCT) strategies in China, 1992-2019. Methods: We built a decision analytic-Markov model to estimate the birth cohorts of 1992-2019. The parameters in our model were referred from literature, published yearbooks, and data from Chinese Center for Disease Control and Prevention. We conducted a univariate sensitivity analysis to test the robustness of the model. Results: For the 28 birth cohorts, the Chinese government has invested 37.43 billion RMB Yuan in direct costs and 47.61 billion RMB Yuan in societal costs on HepB vaccination and HBV prevention of mother to child transmission (PMTCT). And we estimated that about 50 million chronic HBV infections and 12.5 million premature deaths due to HBV-related diseases would be averted. China would save 2.89 trillion RMB Yuan and 6.92 trillion RMB Yuan for the direct and societal medical burden on HBV-related conditions. The direct and societal net benefit was 2.85 trillion RMB yuan 6.87 trillion RMB yuan, respectively. The direct and societal benefit-cost ratios (BCRs) were 77.21 and 145.29, respectively. Conclusion: The strategies of HepB vaccination for HBV PMTCT prevention were cost-effective in China during 1992-2019.

Abstract
Objective: To understand the epidemiological characteristics of hepatitis B in China, evaluate the performance of elimination hepatitis B in China and provide scientific evidence for the prevention and control of hepatitis B. Methods: An analysis was conducted by using the data of hepatitis B cases reported to the National Notifiable Disease Reporting System (NNDRS) from the areas with low, moderate and high hepatitis B prevalence in China from 2013 to 2020, and the information about the diagnoses of the hepatitis B cases were collected, the incidence of hepatitis B was estimated according to the reporting and diagnosis information and the characteristics of acute and chronic hepatitis B were compared. Results: A total of 27 013 hepatitis B cases were reported to NNDRS, including 4 070 acute cases, 21 971 chronic cases and 972 unclassified cases. Among the reported acute hepatitis B cases, 69.9% (2 845/4 070) were confirmed. Among the reported chronic hepatitis B cases, 89.0% (19 548/21 971) were confirmed, and 2.1% (452/21 971) were confirmed as acute cases. It was estimated that the incidence of acute hepatitis B was 4.6/100 000 and the incidence of chronic hepatitis B cases was 54.5/100 000. The case number of acute hepatitis B in age group 31-45 years was highest, accounting for 35.3% (1 164/3 297). The case number of acute hepatitis B in children under 15 years old was lowest, accounting for 0.4% (13/3 297). The case number of chronic hepatitis B in age group 46-60 years was highest, accounting for 34.4% (7 211/20 932). Conclusions: The incidence of acute hepatitis B was in decrease and the incidence of chronic of hepatitis B was in increase in China year by year. It is important to strengthen the standardized diagnosis and treatment of chronic hepatitis B to decrease the morbidity and mortality of hepatitis B. At the same time, it is necessary to standardize the management and reporting of hepatitis B cases reported to NNDRS to improve the accuracy of the reporting of hepatitis B.

Abstract
Objective: To investigate the incidence and determinants of vaccine hesitancy towards national immunization program in China and understand the current status of parents' hesitancy to different vaccines used in national immunization program. Methods: A cross-sectional survey was conducted in Beijing, Sichuan and Gansu. The methods of proportional probability sampling and convenience sampling were used to select the eligible study subjects for questionnaire surveys. Results: A total of 3 592 parents were enrolled in the study, in whom 38.22% fully accepted all the vaccines, 59.35% agreed to let their children to receive all the vaccines but showed slight concern, and 2.42% had hesitancy to the vaccines. The vaccine with the most hesitancy was polio vaccine (0.89%), followed by diphtheria pertussis tetanus vaccine (0.70%) and hepatitis A vaccine (0.64%). The dominant reason for vaccine hesitancy was the risk-benefit perception of vaccination (31.03%), followed by the low awareness of the parents (21.84%) and the inconvenience caused by distance and time (21.84%). Conclusions: The incidence of vaccine hesitancy towards national immunization program was low in parents in China, but over 50% of the parents showed concern to the vaccines. It is essential to improve the service quality of national immunization program and strengthen the health education about the vaccination to reduce the incidence of vaccine hesitancy in parents.

Abstract
OBJECTIVE To investigate the efficacy and safety of intravascular ultrasound (IVUS)-guided rotational atherectomy (RA) combined with cutting balloon for pretreatment of severe calcified lesions in the coronary artery before stent placement. METHODS A total of 120 patients with severe coronary artery calcifications detected by IVUS that required percutaneous coronary intervention (PCI) were recruited from our hospital between January, 2016 to January, 2019. The patients were randomized into two groups for pretreatment of the lesions with semicompliant balloon (SB group, 60 cases) or RA combined with CB (RA+CB group, 60 cases), and drug-eluting stents were implanted after the procedure. The immediate success rate of PCI, vascular parameters detected by IVUS after PCI, and the rates of residual stenosis < 10% were compared between the two groups. The incidences of intraoperative complications and major adverse cardiac events (MACE) within 24 months after the surgery were also observed in the two groups. RESULTS The immediate success rate was significantly higher in RA+CB group than in SB group (P=0.032). After pretreatment and stent placement, the minimum stent lumen diameter (P=0.035), minimum stent lumen cross-sectional area (P=0.029), immediate lumen acquisition, immediate lumen cross-sectional area acquisition and the rate of residual stenosis < 10% were all significantly higher in RA+CB group than in SB group (P < 0.001). The patients in RA+ CB group showed obviously less residual stenosis of lumen cross-sectional area than those in SB group after the surgery (χ2= 7.859, P=0.005). The incidences of intraoperative complications (χ2=5.997, P=0.014) and MACE within 24 months after the operation (χ2=4.285, P=0.038) were significantly lower in RA+CB group than in SB group. CONCLUSION For patients with severe coronary artery calcifications eligible for PCI, RA combined with CB angioplasty can significantly improve the success rate of immediate PCI, expand the lumen diameter and cross-sectional area of the stent after PCI, enhance immediate lumen gain, and reduce the incidence of intraoperative complications and MACE after the operation.

Abstract
Objective: To explore the relationship between age at menarche and general obesity (based on BMI) and central obesity (based on WC or WHtR) in middle-aged and elderly women in China. Methods: A total of 6 363 women from the China Health and Retirement Longitudinal Study were included. Restricted cubic splines based on binary logistic regressions were used to analyze the relationship between age at menarche and the risk of obesity. Age at menarche was divided into four groups: ≤13, 14- (control group), 16- , and ≥18 years old. Binary logistic regressions were applied to analyze the relationship between the continuous or grouped variable of age at menarche and the risk of obesity. Results: After adjusting potential confounders, the age at menarche showed a negative linear relationship with the risk of general obesity and central obesity. The risk for obesity based on BMI, WC and WHtR significantly decreased by 6% (OR=0.94, 95%CI: 0.90-0.99), 4% (OR=0.96, 95%CI: 0.92-1.00), and 6% (OR=0.94, 95%CI: 0.90-0.99) for each 1 year increase in age at menarche. Compared with participants who had menarche at age 14- years old, the risk for obesity based on BMI (OR=0.71, 95%CI: 0.55-0.91), WC (OR=0.75, 95%CI: 0.62-0.92) and WHtR (OR=0.76, 95%CI: 0.61-0.96) significantly decreased by 29%, 25%, and 24% in participants who had menarche at age ≥18 years old. Conclusions: There was a negative linear relationship between age at menarche and the risk for general obesity and central obesity in middle-aged and elderly women in China. Older age at menarche might be negatively associated with risk for obesity in middle-aged and elderly women.

Abstract
In order to curve the ongoing trend of the COVID-19 pandemic and save more lives, effective treatments against COVID-19 are urgently needed. Comparing to developing new drugs, which may take too much time, it's more efficient and cost-effective to repurpose existing drugs in the treatment of COVID-19. Fortunately, some of the shared features of COVID-19 and other well-known diseases make it possible to use old strategies to combat this new challenge. In this paper, we reviewed various possible strategies of drug repurposing in the treatment of COVID-19 and explored the possible scientific mechanisms behind each strategy.

Abstract
Breeding for good meat quality performance while maintaining large body size and desirable carcass traits has been the major challenge for modern swine selective breeding. To address this goal, in the present work we studied five related populations produced by two commercial breeds (Berkshire and Duroc) and two Chinese breeds (Licha black pig and Lulai black pig). A single-trait GWAS performed on 20 body size and carcass traits using a self-developed China Chip-1 porcine SNP50K BeadChip identified 11 genome-wide significant QTL on nine chromosomes and 22 suggestive QTL on 15 chromosomes. For the 11 genome-wide significant QTL, eight were detected in at least two populations, and the rest were population-specific and only mapped in Shanxia black pig. Most of the genome-wide significant QTL were pleiotropic; for example, the QTL around 75.65 Mb on SSC4 was associated with four traits at genome-wide significance level. After screening the genes within 50 kb of the top SNP for each genome-wide significant QTL, NR6A1 and VRTN were chosen as candidate genes for vertebrae number; PLAG1 and BMP2 were identified as candidate genes for body size; and MC4R was the strong candidate gene for body weight. The four genes have been reported as candidates for thoracic vertebrae number, lumbar vertebrae number, carcass length and body weight respectively in previous studies. The effects of VRTN on thoracic vertebrae number, carcass length and body length have been verified in Shanxia black pig. Therefore, the VRTN genotype could be used in gene-assisted selection, and this could accelerate genetic improvement of body size and carcass traits in Shanxia black pig.

Abstract
Objective: To analyze the clinical features, genetic characteristics, treatment and follow-up results of patients with hydrocephalus caused by methylmalonic acidemia combined with homocysteinuria, and to discuss the optimal strategies for assessing and treating such patients. Methods: From January 1998 to December 2020, 76 patients with hydrocephalus due to methylmalonic acidemia combined with homocysteinuria in the Department of Pediatrics in 11 hospitals including Peking University First Hospital were diagnosed by biochemical, genetic analysis and brain imaging examination. The patients were divided into operation-group and non-operation-group according to whether they underwent ventriculoperitoneal shunt. The clinical features, laboratory examinations, genotype, and follow-up data were retrospectively analyzed. Data were compared between the two groups using rank sum test, and categorical data were compared using χ2 test. Results: Among the 76 patients (51 male, 25 female), 5 were detected by newborn screening, while 71 were diagnosed after clinical onset, 68 cases (96%) had early-onset, 3 cases (4%) had late-onset. The most common clinical manifestations of 74 cases with complete data were psychomotor retardation in 74 cases (100%), visual impairment in 74 cases (100%), epilepsy in 44 cases (59%), anemia in 31 cases (42%), hypotonia or hypertonia in 21 cases (28%), feeding difficulties in 19 cases (26%) and disturbance of consciousness in 17 cases (23%). Genetic analysis was performed in 76 cases, all of whom had MMACHC gene variations, including 30 homozygous variations of MMACHC c.609G>A. The most common variations were c.609G>A (94, 62.7%), followed by c.658_660del (18, 12.0%), c.567dupT (9, 6.0%) and c.217C>T (8, 5.3%). Therapy including cobalamin intramuscular injection, L-carnitine and betaine were initiated immediately after diagnosis. A ventriculoperitoneal shunt operation was performed in 41 cases (operation group), and 31 patients improved after metabolic intervention (non-operation group). There was no significant difference in the age of onset, the age of diagnosis, the blood total homocysteine, methionine, and urinary methylmalonic acid concentration between the two groups (all P>0.05). The symptoms of psychomotor development, epilepsy, and visual impairments improved gradually after a long-term follow-up in the operation group. Conclusions: Hydrocephalus is a severe complication of methylmalonic acidemia combined with homocysteinuria. The most common clinical manifestations are psychomotor retardation, visual impairment, and epilepsy. It usually occurs in early-onset patients. Early diagnosis and etiological treatment are very important. Hydrocephalus may improve after metabolic intervention in some patients. For patients with severe ventricular dilatation, prompt surgical intervention can improve the prognosis.

Abstract
The Yijing Dazhi (, Great Illustrated Directions on Medical Classics) was written by Haiyan He Yue in the Ming Dynasty. This book cited some sections from the Danxi Yi An ( , Danxi's Medical Cases), and some cases in this book were new discoveries. Using the method of philology, this paper compared the cited sections from the Danxi Yi An () in The Yijing Dazhi with the medical records in Danxi Yi An (), Gezhi Yu Lun (, Further Discourses on the Properties of Things), Danxi Zuanyao (, Collected Essentials of Master Danxi's Medical Book), and Danxi Zhifa Xinyao (, Heart and Essentials of Danxi's Treatment Methods). It found that Danxi Yi An() and Danxi Yi An () are actually two individual books. In addition, the contents of Yijing Dazhi cited from Danxi Yi An () are well preserved and have important reference value for collating the medical records of Zhu Danxi in other relevant medical archives.

Abstract
Objective: To evaluate the effect of transfusion-free techniques on the prognosis of liver transplant patients. Methods: The recipients of adult liver transplantation at Tianjin First Central Hospital from August to December 2019 were included in the clinical observation. Liver transplantation without allogeneic blood transfusion was performed through anesthesia management techniques such as acute hemodilution or phlebotomy without volume replacement,maintaining decreased baseline central venous pressure and cell saver. According to the actual results,the patients were divided into two groups: transfusion-free group(n=21) and allogeneic transfusion group(n=28). There were 13 males and 8 females aged of (56.3±11.6) years in the transfusion-free group;and there were 16 males and 12 females aged (54.3±14.2)years in the allogeneic transfusion group. The transplant recipients who had not adopted transfusion management strategy from January to July 2019 were included as control group(27 males and 13 females,aged of (58.9±14.1)years). The clinical data of patients in perioperative period were collected to compare whether there were differences in the recovery of liver function and early complications among the three groups, one-way ANOVA test, rank-sum test, and χ2 test were used for data analysis. Results: The amount of intraoperative blood loss in both the transfusion-free group and the transfusion group was less than that in the control group((454.2±271.3)ml vs.(673.6±333.4)ml vs.(890.3±346.7)ml;q=-6.342,-5.286,both P<0.05).The duration of stay in ICU of the transfusion-free group was less than that of the transfusion group and control group((36.4±9.1)hours vs.(44.3±14.9)hours vs.(58.2±21.1)hours;q=-4.432,-3.824,both P<0.05).The mean ALT level at 7 days after operation was significantly lower in the transfusion-free group than in the control group((56.8±32.1)U/L vs.(89.6±45.6)U/L;q=-3.358,P<0.05). Conclusions: The improvement of multi-disciplinary transfusion management technology aimed at transfusion-free liver transplantation can effectively reduce intraoperative hemorrhage and help to avoid surgical transfusion. Transfusion-free liver transplantation is beneficial to the early postoperative recovery,and its long-term clinical significance is worthy of further clinical research.

Abstract
OBJECTIVE This study aimed to identify the different expression of microRNAs (miRNAs) in the plasma derived exosomes of patients with esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS A total of 9 patients with ESCC and 9 patients with benign diseases were involved. miRNA sequencing was performed to screen differential expression of microRNAs in plasma exosomes between patients with ESCC and controls. The function of miRNA on proliferation and migration abilities was determined by CCK-8 analysis, wound scratch and transwell test. Predicted target genes were screened by databases and confirmed by RT-qPCR. RESULTS We identified a total of 10 miRNAs (7 upregulated and 3 downregulated) that were differentially expressed in plasma exosomes between patients with ESCC and control patients (fold change, FC ≥ 2.0 or ≤ -2.0, p ≤ 0.05) by miRNA sequencing. Ten miRNAs were detected by qRT-PCR to verify the results of the miRNA sequencing. MiR-103a-2-5p demonstrated the most significant differential expression in both exosomes of ESCC cell lines and plasma of patients as compared with control patients and was therefore selected for subsequent functional experiments. Overexpression of miR-103a-2-5p promoted proliferation and migration in TE-1 cells, whereas inhibition of miR-103a-2-5p suppressed proliferation and migration in KYSE-150 cells. Exosomes extracted from the cells transfected with miR-103a-2-5p mimics significantly increased the proliferation and migration of two ESCC cell lines. Two genes, CDH11 and NR3C1 were identified as predicted targets of miR-103a-2-5p by the bioinformatics tools TargetScan, MiRanda, and mirDIP and RT-qPCR. CONCLUSIONS Our results shed light on how exosomal miR-103a-2-5p can promote proliferation and migration of ESCC cells and may represent a potential target for ESCC therapies.
