Abstract
Covalent organic frameworks (COFs) are a new kind of crystalline porous materials composed of organic molecules connected by covalent bonds, processes the characteristics of low density, large specific surface area, adjustable pore size and structure, and easy to functionalize, which have been widely used in the field of membrane separation technology. Recently, there are more and more researches focusing on the preparation methods, separation application, and mechanism of COF membranes, which need to be further summarized and compared. In this review, we primarily summarized several conventional preparation methods, such as two-phase interfacial polymerization, in-situ growth on substrate, unidirectional diffusion method, layer-by-layer assembly method, mixed matrix membranes, and so on. The advantages and disadvantages of each method are briefly summarized. The application potential of COF membrane in liquid separation are introduced from four aspects: dyeing wastewater treatment, heavy metal removal, seawater desalination and oil-water separation. Then, the mechanisms including pore structure, hydrophilic/hydrophobic, electrostatic repulsion/attraction and Donnan effect are introduced. For the efficient removal of different kind of pollutions, researchers can select different ligands to construct membranes with specific pore size, hydrophily, salt or organic rejection ability and functional group. The ideas for the design and preparation of COF membranes are introduced. Finally, the future direction and challenges of the next generation of COF membranes in the field of separation are prospected.

Abstract
Echinococcosis poses a significant threat to public health. The Chinese government has implemented prevention and control measures to mitigate the impact of the disease. By analyzing data from the Chinese Center for Disease Control and Prevention and the State Council of the People's Republic of China, we found that implementation of these measures has reduced the infection rate by nearly 50% between 2004 to 2022 (from 0.3975 to 0.1944 per 100,000 person-years). Nonetheless, some regions still bear a significant disease burden, and lack of detailed information limites further evaluation of the effects on both alveolar and cystic echinococcosis. Our analysis supports the continuing implementation of these measures and suggests that enhanced wildlife management, case-based strategies, and surveillance systems will facilitate disease control.

Abstract
Objective: To compare the point-of-care assays for tear matrix metalloproteinase 9 (MMP-9) using domestic and InflammaDry kits, and to evaluate the feasibility of diagnosing dry eye with the domestic kit. Methods: It was a cross-sectional study. Thirty dry eye patients and 30 age-and sex-matched normal volunteers were continuously enrolled in this cross-sectional study from June 2022 to July 2022. Both domestic and InflammaDry kits were used to detect the tear MMP-9 levels. The positive rates were recorded for qualitative analysis, and the gray ratios of bands (the gray value of detection bands to that of control bands) were collected for quantitative analysis. The correlations of MMP-9 levels with age, ocular surface disease index, fluorescence tear break-up time, tear meniscus height, Schirmer's Ⅰ test score, corneal fluorescein staining score, and meibomian gland dropout were analyzed. The Mann-Whitney U test, paired Chi-square test, Kappa test, and Spearman's correlation coefficient were used for statistical analysis. Results: There were 14 males and 16 females (30 eyes) in the control group, and their age was (39.37±19.55) years. In the dry eye group, 11 males and 19 females (30 eyes), aged (46.87±17.85) years, had moderate to severe dry eye. The positive rates of MMP-9 in tear fluid were significantly different between dry eye patients (InflammaDry: 86.67%; domestic kit: 70.00%) and controls (InflammaDry: 16.67%, P<0.001; domestic kit: 6.67%, P<0.001). Although the sensitivity of the domestic kit was lower than that of the InflammaDry kit (70.0% vs. 86.7%, P=0.001), the specificity was higher (93.3% vs. 83.3%, P=0.001). In dry eye patients, the positive coincidence rate was 80.7% (21/26), the negative coincidence rate was 100% (4/4), and the total coincidence rate was 83.3% (25/30), with no significant difference between the two kits (McNemar test: χ2=3.20, P>0.05), and the results of both kits were consistent (Kappa=0.53, P=0.001). The Spearman's correlation coefficient showed the gray ratios using both kits were positively correlated with the corneal fluorescein staining score (InflammaDry: ρ=0.48, P<0.05; domestic kit: ρ=0.52, P=0.003). Conclusion: The performances of the domestic and InflammaDry kits are consistent in the point-of-care assay for tear MMP-9, and the domestic kit has lower sensitivity but higher specificity.

Abstract
Objective: To explore whether hsa_circ_0000670 promotes the progression of gastric cancer by regulating the miR-515-5p/SIX1 molecular axis. Methods: The gastric cancer and adjacent normal tissues of 35 gastric cancer patients admitted to Rugao Hospital Affiliated to Nantong University from 2014 to 2015 were collected. The expression levels of circ_0000670, miR-515-5p and Sine oculis homeobox 1 (SIX1) in gastric cancer tissues and cells were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. The correlations between circ_0000670 and miR-515-5p, miR-515-5p and SIX1, circ_0000670 and SIX1 were analyzed by the Pearson method. Patients were divided into low circ_0000670 expression group (17 cases) and high circ_0000670 expression group (18 cases) based on the median of circ_0000670 expression level, and Kaplan-Meier was used to analyze the 5-year survival of patients. Cell proliferation was assessed via clone formation assay. Cell cycle and apoptosis were detected by flow cytometry. Wound healing and Transwell assays were used to detect cell migration and invasion ability. The targeting relationship between miR-515-5p and circ_0000670 or SIX1 was confirmed by the dual luciferase reporter assay. Nude mice were injected into HGC-27 cells transfected with sh-NC or sh-circ_0000670, and the volume and weight of the transplanted tumor were measured, also, the levels of circ_0000670, miR-515-5p and SIX1 in the transplanted tumor tissue were detected. Results: The expression levels of circ_0000670 and SIX1 in gastric cancer tissues and cell lines were significantly increased (P<0.05), while the expression levels of miR-515-5p were significantly decreased (P<0.05). The survival rate of patients in the low circ_0000670 expression group (82.4%) was significantly higher than that in the high circ_0000670 expression group (28.7%, P=0.034). Circ_0000670 was negatively correlated with miR-515-5p (r=-0.846, P<0.001), and miR-515-5p was negatively correlated with SIX1 (r=-0.615, P<0.001), but circ_0000670 was positively correlated with SIX1 (r=0.814, P<0.001). Transfection of si-circ_0000670 or miR-515-5p mimic could significantly reduce the number of clone-forming cells, migration distance, migration and invasion cells (P<0.05), and increase the ratio of G(0)/G(1) phase cells, apoptosis rate and the protein level of E-cadherin (P<0.05), decreased the proportion of S-phase cells and the protein level of Vimentin (P<0.05). The dual luciferase report assay confirmed that circ_0000670 could target miR-515-5p, and miR-515-5p could bind to SIX1. Co-transfection of si-circ_0000670 and miR-515-5p inhibitor could significantly attenuate the effects of si-circ_0000670 on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Co-transfection of miR-515-5p mimic and pcDNA-SIX1 could significantly reduce the effects of miR-515-5p mimic on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Compared with the sh-NC group [volume=(596.20±125.46) mm(3) and weight=(538.00±114.39) g], the volume and weight of transplanted tumors in the sh-circ_0000670 group [volume=(299.20±47.58) mm 3 and weight=(289.80±48.73 g)] were significantly reduced (P<0.05), the expression levels of circ_0000670 and SIX1 were significantly reduced (P<0.05), and the expression level of miR-515-5p was significantly increased (P<0.05). Conclusion: Knockdown of circ_0000670 could inhibit cell proliferation, migration, invasion of gastric cancer cells, induce cell cycle arrest in G(0)/G(1) phase and promote cell apoptosis by regulating the miR-515-5p/SIX1 axis.

Abstract
In this study, the facile carbothermal reduction method was enforced using urea as dopant to modify the structure and chemical composition of nanoscale zero-valent-iron/biochar hybrid thereby boosting its reduction performance. Through fine-tuning the N-doped amount, the optimal nZVI/N-doped BC was obtained, which exhibited more active sites (nZVI, persistent free radicals (PFRs), pyrrolic-N) and superior electrochemical conductivity. With these blessings, the electrons originating from galvanic cell reaction could zip along the highway within the hybrid. Taking nitrobenzene (NB) as the target pollutant, the quantitative analysis revealed that the NB reduction and adsorption removal efficiency were dramatically improved by 2.42 and 2.78 times, respectively. What's more, combining the in-situ experimental detection and theoretical calculations, unexpected NB reductive multipath with respect to PFRs and pyrrolic-N accelerating the Fe3+/Fe2+ cycle within the nZVI/N-doped BC system was decoded. The enhancement of Fe3+/Fe2+ cycle improved the electron utilization efficiency and maintained the reduction reactivity of the hybrid. This work raised awareness of the mechanisms regarding the reduction performance of nZVI/N-doped BC elevated by N-doped and the pollutant reductive pathway within the system, uncovered the dusty roles of PFRs and N-species during the reduction process.

Abstract
OBJECTIVES Dietary Approaches to Stop Hypertension (DASH) pattern has been found to aid in the reduction of obesity, oxidative stress, and chronic inflammation, which are all strongly linked to the development of head and neck cancer (HNC). Nevertheless, no epidemiological studies have investigated the association between this dietary pattern and HNC risk. This study was conducted with the purpose of bridging this gap in knowledge. DESIGN A prospective cohort study involving 98,459 American adults aged 55 years and older. SETTING AND PARTICIPANTS Data were drawn from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Trial. In the present study, participants with dependable energy intake data who furnished baseline and dietary history information were identified as the study population. METHODS Diet was assessed by food frequency questionnaires and the DASH score was calculated to assess each participant's adherence to DASH eating pattern. Cox proportional hazards models were used to calculate multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the occurrence of HNC. To visualize the variation in cancer risk for HNC and its subtypes across the entire spectrum of DASH scores, restricted cubic spline plots were utilized. Additionally, a series of predefined subgroup analyses were performed to identify potential effect modifiers, and several sensitivity analyses were conducted to assess the stability of the findings. RESULTS During a follow-up period of 871,879.6 person-years, 268 cases of HNC were identified, comprising 161 cases pertaining to oral cavity and pharynx cancers, as well as 96 cases of larynx cancer. In the fully adjusted model, adherence to the DASH diet was associated with a remarkable 57% reduction in the risk of HNC when comparing extreme quartiles (HR quartile 4 vs 1: 0.43; 95% CI: 0.28, 0.66; P for trend < 0.001). The restricted cubic spline plots demonstrated a linear dose-response relationship between the DASH score and the risk of HNC as well as its subtypes. Subgroup analysis revealed that the protective effect of the DASH diet against HNC was particularly pronounced in individuals with lower daily energy intake. The primary association remained robust in the sensitivity analysis. CONCLUSIONS In American middle-aged and older population, adherence to the DASH diet may help prevent HNC, particularly for individuals with lower daily energy intake.

Abstract
Background Numerous studies have suggested that ferroptosis plays a significant role in the development of polycystic ovary syndrome (PCOS), but the mechanism remains unclear. Methods In this study, we explored the role of ferroptosis-related genes in the pathogenesis of PCOS using a comprehensive bioinformatics method. First, we downloaded several Gene Expression Omnibus (GEO) datasets and combined them into a meta-GEO dataset. Differential expression analysis was performed to screen for significant ferroptosis-related genes between the normal and PCOS samples. The least absolute shrinkage selection operator regression and support vector machine-recursive feature elimination were used to select the best signs to construct a PCOS diagnostic model. Receiver operating characteristic curve analysis and decision curve analysis were applied to test the performance of the model. Finally, a ceRNA network-related ferroptosis gene was constructed. Results Five genes, namely, NOX1, ACVR1B, PHF21A, FTL, and GALNT14, were identified from 10 differentially expressed ferroptosis-related genes to construct a PCOS diagnostic model. Finally, a ceRNA network including 117 lncRNAs, 67 miRNAs, and five ferroptosis-related genes was constructed. Conclusion Our study identified five ferroptosis-related genes that may be involved in the pathogenesis of PCOS, which may provide a novel perspective for the clinical diagnosis and treatment of PCOS.

Abstract
BACKGROUND Sodium formononetin-3'-sulphonate (Sul-F) may alleviate I/R injury in vivo with uncertain mechanism. Endoplasmic reticulum (ER) stress-mediated apoptosis participates in the process of cerebral ischemia-reperfusion (I/R) injury. Our aim is to figure out the effect of Sul-F on cerebral I/R injury and to verify whether it works through suppressing ER stress-mediated apoptosis. RESULTS The cerebral lesions of middle cerebral artery occlusion (MCAO) model in SD rats were aggravated after 24 h of reperfusion, including impaired neurological function, increased infarct volume, intensified inflammatory response and poor cell morphology. After intervention, the edaravone (EDA, 3 mg/kg) group and Sul-F high-dose (Sul-F-H, 80 mg/kg) group significantly alleviated I/R injury via decreasing neurological score, infarct volume and the serum levels of inflammatory factors (TNF-α, IL-1β and IL-6), as well as alleviating pathological injury. Furthermore, the ER stress level and apoptosis rate were elevated in the ischemic penumbra of MCAO group, and were significantly blocked by EDA and Sul-F-H. In addition, EDA and Sul-F-H significantly down-regulated the ER stress related PERK/eIF2α/ATF4 and IRE1 signal pathways, which led to reduced cell apoptosis rate compared with the MCAO group. Furthermore, there was no difference between the EDA and Sul-F-H group in terms of therapeutic effect on cerebral I/R injury, indicating a therapeutic potential of Sul-F for ischemic stroke. CONCLUSIONS Sul-F-H can significantly protects against cerebral I/R injury through inhibiting ER stress-mediated apoptosis in the ischemic penumbra, which might be a novel therapeutic target for ischemic stroke.

Abstract
Objective: To examine the association of body mass index (BMI) and waist circumference (WC) with frailty among oldest-old adults in China. Methods: A total of 7 987 people aged 80 years and older (oldest-old) who participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2017-2018 were included. Information on demographic characteristics, behavior pattern, diet, activities of daily living, cognitive function, health status, disease condition were collected by questionnaire and physical examination. Generalized linear mixed model and restricted cubic splines (RCS) were used to analyze the association of BMI and WC with frailty. Results: The mean age of all participants was 91.7 years, and their mean BMI and WC were (21.3±3.5) kg/m2 and (82.9±10.5) cm, respectively. The proportion of male was 42.3% (3 377/7 987), and the proportion of people with frailty was 33.7% (2 664/7 987). After controlling confounding factors, compared with T2 (19.1-22.1 kg/m2) of BMI, the OR (95%CI) of the female T1 (<19.1 kg/m2) and T3 (≥22.2 kg/m2) group was 1.39 (1.17-1.65) and 1.27 (1.07-1.52), respectively. Compared with T2 (77-85 cm) of WC, the OR (95%CI) of female T1 (<77 cm) and T3 (≥86 cm) group was 1.20 (1.01-1.42) and 1.10 (0.93-1.31), respectively. The results of multiple linear regression model with restrictive cubic spline showed that there was a non-linear association of BMI and WC with frailty in female. Conclusion: There is a U-shaped association of BMI and WC with frailty in female participants.

Abstract
Objective: To explore the impact of composite clinical worsening (cCW) events and its components on the prognosis of patients with pulmonary arterial hypertension associated with congenital heart disease (CHD-PAH). Methods: This is a retrospective study. Patients who were diagnosed with CHD-PAH in Beijing Anzhen Hospital between January 2007 and July 2018, were included, and their baseline clinical data including demographic, clinical manifestations and New York Heart Association (NYHA) classification were collected retrospectively. All-cause deaths and clinical worsening events were recorded, which included syncope, PAH related hospitalization, NYHA classification deterioration and ≥ 2 PAH related clinical symptoms (dyspnea, hemoptysis, edema, chest pain, palpitations, cyanosis) appearance/progress. Three kinds of cCW events were defined: cCW1 (included PAH related hospitalization, NYHA classification deterioration), cCW2 (increased syncope on the basis of cCW1) and cCW3 (increased ≥ 2 PAH related clinical symptoms appearance/progress on the basis of cCW2). The Kaplan-Meier survival curve was used to analyze the long-term survival of the included patients. Univariate and multivariate Cox regression models were used to evaluate the impact of cCW events and their components on the risk of all-cause mortality. Results: A total of 525 patients with CHD-PAH were included in this study. The median age at diagnosis was 20.7 (11.2, 30.3) years. There were 43.8% children (<18 years), and 68.8% female patients. There were 431 patients (82.1%) with NYHA classification II. A total of 180 patients had PAH symptoms at diagnosis. The median follow-up time was 4.5 (2.6, 6.7) years. Forty-seven patients (9.0%) died during the follow-up period. Survival rates at 1, 5 and 10 years after diagnosis of PAH were 98.0%, 89.9% and 84.4%, respectively. Cox multivariate analysis showed that NYHA classification deterioration (HR=3.901, 95%CI 1.863-8.169, P<0.001), ≥2 PAH symptoms appearance/progress (HR=4.458, 95%CI 1.870-10.625, P<0.001), PAH-related hospitalization (HR=4.058, 95%CI 1.851-8.896, P<0.001) and syncope (HR=11.313, 95%CI 4.860-26.332, P<0.001) were independent predictors of increased risk of death. All 3 kinds of cCW events were significantly associated with the significantly increased risk of death, and cCW2 was highly predictive to increased risk of death (HR=15.476, 95%CI 4.346-37.576, P<0.001). Conclusions: The overall long-term prognosis of CHD-PAH patients in this study is relatively good. cCW events and its components (NYHA classification deterioration, ≥2 PAH symptoms occurrence/worsening, PAH-related hospitalization and syncope) have adverse influence on all-cause death in this patient cohort.

Abstract
AbstractA flexible approach to both type II and III lepadin alkaloids is developed for the first time. A key Diels–Alder reaction based on a novel chiral ketolactone dienophile is employed to obtain the desirable all-cis-trisubstituted cyclohexene with excellent regio- and stereoselectivity. As the subsequent closure of the piperidine ring is devised at the N1 and C2 position via an intramolecular nucleophilic amination, the two stereochemical types of lepadin frameworks with the opposite configuration at C2 can be conveniently accessible from a common intermediate. By the approach, lepadins D, E (type II) and F (type III) are stereoselectively synthesized from ethyl l-lactate.

Abstract
A porous carbon obtained from cotton/polyester textile wastes was synthesized by the calcium acetate template method. This research studied the effect of preparation conditions and evaluated the characterization of porous carbon, and further explored its formation mechanism. The porous carbon possessed a high specific surface area of 1106.63 m2/g under an optimum condition (pyrolysis temperature = 800 °C, mass ratio of CA: CPW = 1.5:1, pyrolysis time = 1.5 h). It was found that calcium acetate played the role of catalyst to promote the degradation of cotton/polyester textile. CaCO3 and CaO fabricated by calcium acetate acted as the template to generate a mesoporous structure. The generated CO2 etched carbon skeleton to create a large number of micropores. Besides, it was supported as the carbon source to fuse with carbon structures, further consolidating the aromatic structures of porous carbon. The optimized porous carbon has a high adsorption capacity of 506.40 mg/g for tetracycline. And the adsorption data fitted better by the first-pseudo-order model and Langmuir isotherms with an endothermic and spontaneous adsorption process. The cotton/polyester-based porous carbon was a promising economical material for tetracycline.

Abstract
The feasibility of submandibular gland (SMG) preservation during neck dissection has been described. The aim of this study was to analyse the functional outcomes in patients undergoing SMG preservation during neck dissection for cT1-2N0 oral squamous cell carcinoma. Consecutive patients were divided into two groups based on the management of the SMG, and underwent a saliva flow test before surgery, 7 days after surgery, and at 3, 6, 9, and 12 months after surgery. All enrolled patients completed the fourth version of the University of Washington Quality of Life (UWQOL) questionnaire at 12 months after surgery. In patients who underwent SMG preservation during neck dissection, the flow rate at 7 days after surgery was significantly lower than that preoperative; however, it gradually returned to baseline at 9 months after surgery. The saliva flow rate at 9 months after surgery was similar to that at 12 months after surgery. Further, patients with SMG preservation had higher scores for the activity, swallowing, chewing, and saliva domains than patients without SMG preservation. The results of the study suggest that saliva secretion ability can be preserved following SMG-sparing neck dissection, and that SMG preservation improves postoperative quality of life.

Abstract
Introduction Presence of heart failure is associated with a poor prognosis in patients with COVID-19. The aim of the present study was to examine whether first-phase ejection fraction (EF1), the ejection fraction measured in early systole up to the time of peak aortic velocity, a sensitive measure of pre-clinical heart failure, is associated with survival in patients hospitalised with COVID-19. Methods A retrospective outcome study was performed in patients hospitalised with COVID-19 who underwent echocardiography (n=380) at the West Branch of the Union Hospital, Wuhan, China and in patients admitted to King's Health Partners in South London UK. Association of EF1 with survival was performed using Cox proportional hazards regression. EF1 was compared in patients with COVID-19 and in historical controls with similar co-morbidities (n=266) who had undergone echocardiography before the COVID-19 pandemic. Results In patients with COVID-19, EF1 was a strong predictor of survival in each patient group (Wuhan and London). In the combined group, EF1 was a stronger predictor of survival than other clinical, laboratory and echocardiographic characteristics including age, co-morbidities and biochemical markers (figure 1). A cut-off value of 25% for EF1 gave a hazard ratio of 5.23 (95% CI: 2.85–9.60, p<0.001) unadjusted and 4.83 (95% CI: 2.35–9.95, p<0.001) when adjusted for demographics, co-morbidities, hs-cTnI and CRP (figure 2). EF1 was similar in patients with and without COVID-19 (23.2±7.3 vs 22.0±7.6%, p=0.092, adjusted for prevalence of risk factors and co-morbidities). Conclusion Impaired first-phase ejection fraction is strongly associated with mortality in COVID-19 and probably reflects pre-existing, pre-clinical heart failure.

Abstract
Objective: To investigate the effect of plasma uric acid level on the incident risk of type 2 diabetes mellitus (T2DM) among the oldest old (those aged ≥80 years). Methods: Participants were recruited from the Healthy Aging and Biomarkers Cohort Study (HABCS), which conducted a baseline survey in 2008-2009 and follow-up of 3 times in 2011-2012, 2014, and 2017-2018, respectively. A total of 2 213 oldest old were enrolled in this study. The general demographic, socioeconomic, lifestyle and disease data of the oldest old were collected, and physical measurements were made for the oldest old. Fasting venous blood was collected for uric acid and blood glucose detection. Information on the incident and death of T2DM were collected through the follow-up. Cox proportional hazard regression model was used to explore the association of hyperuricemia and plasma uric acid level with the incidence of T2DM. Restricted cubic spline (RCS) function was used to explore the dose-response relationship of plasma uric acid levels with the risk of T2DM. Results: The age of participants was (93.2±7.6) years old, and 66.7% of the participants (1 475) were female. The plasma uric acid level at baseline was (289.1±88.0)μmol/L, and the prevalence of hyperuricemia was 13.3% (294 cases). During 9 years of cumulative follow-up of 7 471 person-years (average of 3.38 years for each), 122 new cases of T2DM occurred and the incidence density was 1 632.98/105 person year. Cox proportional hazards regression analysis showed that per 10μmol/L increase in plasma uric acid level, the risk of T2DM increased by 1.1% [HR (95%CI): 1.011 (1.004, 1.017)]. Compared with the participants with the lowest quintile of plasma uric acid (Q1), the risk of diabetes increased by 20.7 % among the oldest old with uric acid in the highest quintile (Q5) [HR (95%CI):1.207 (1.029, 1.416)]. The risk of T2DM was 19.2% higher in the hyperuricemia group than that in the oldest old with normal plasma uric acid [HR (95%CI): 1.192 (1.033, 1.377)]. RCS function showed that the risk of T2DM increased with the increase in plasma uric acid levels in a nonlinear dose-response relationship (P=0.016). Conclusion: The incident risk of T2DM increases with the elevates of plasma uric acid levels in the oldest old.

Abstract
BACKGROUND Late recovery in patients following prolonged coma from carbon monoxide poisoning have been reported, but the probability is unclear. The purpose of this research was to assess the prognosis of patients in prolonged coma after severe carbon monoxide poisoning and related clinical and imaging features. METHODS There were 13 patients who had been in a state of coma for >7 days after acute carbon monoxide poisoning in the retrospective observational study, and demographic data, clinical data, laboratory data, complications, and image data were collected. Outcome was assessed by means of the Glasgow outcome scale after 1 year. The relationship between complications and imaging manifestations and prognosis was also analyzed. RESULTS One year after severe carbon monoxide poisoning, two patients (15.4%) had died (GOS 1), nine (69.2%) were in a persistent vegetative state (GOS 2), one (7.7%) was moderately disabled (GOS 4), and one (7.7%) achieved a good recovery (GOS 5) with minimal disability. CONCLUSIONS Most patients with prolonged coma after severe carbon monoxide poisoning had a poor prognosis, although the younger patients had a better prognosis. Respiratory failure, hypotension and renal failure during the course of the disease were associated with a poor prognosis. The prognosis of patients with injuries in two sites in early CT was poor. Multiple lesions (≥3) and extensive white matter damage (Fazekas grade (PVH or DWMH) = 3) on MRI of chronic phase were also associated with a poor prognosis.

Abstract
Obstructive sleep apnea (OSA) is a highly prevalent sleep disorder that is associated with many cardiovascular complications. Similar to OSA, chronic intermittent hypoxia (CIH) (a model for OSA) leads to oxidative stress and impairs baroreflex control of the heart rate (HR) in rodents. The baroreflex arc includes the aortic depressor nerve (ADN), vagal efferent, and central neurons. In this study, we used mice as a model to examine the effects of CIH on baroreflex sensitivity, aortic baroreceptor afferents, and central and vagal efferent components of the baroreflex circuitry. Furthermore, we tested whether human Cu/Zn Superoxide Dismutase (SOD1) overexpression in transgenic mice offers protection against CIH-induced deficit of the baroreflex arc. Wild-type C57BL/6J and SOD1 mice were exposed to room air (RA) or CIH and were then anesthetized, ventilated, and catheterized for measurement of mean arterial pressure (MAP) and HR. Compared with wild-type RA control, CIH impaired baroreflex sensitivity but increased maximum baroreceptor gain and bradycardic response to vagal efferent stimulation. Additionally, CIH reduced the bradycardic response to ADN stimulation, indicating a diminished central regulation of bradycardia. Interestingly, SOD1 overexpression prevented CIH-induced attenuation of HR responses to ADN stimulation and preserved HR responses to vagal efferent stimulation in transgenic mice. We suggest that CIH decreased central mediation of the baroreflex and SOD1 overexpression may prevent the CIH-induced central deficit.

Abstract
An efficient approach to the type III lepadin alkaloids (lepadins F and G) has been developed through a key Diels-Alder reaction, in which a novel ketolactone-type dienophile with chiral diol unit is employed to generate the desirable all-cis-trisubstituted cyclohexene with excellent regio- and stereoselectivity control. The subsequent selective sulfonylation of the diol unit followed by SN 2 cyclization under hydrogenation conditions could construct the substituted piperidine ring. By using this approach, (-)-lepadin F is synthesized from ethyl l-lactate for the first time.

Abstract
The cotton textile was an abundant energy resource while was otherwise treated as waste. In this work, surfactants were used as catalysts in the hydrothermal carbonization (HTC) to transform cotton textile waste (CTW) into clean solid fuel. Furthermore, the conversion mechanisms of hydrothermal products during surfactant-assisted HTC were preliminarily proposed. The results showed that Span 80 and sodium dodecylbenzenesulfonate facilitated the transformation of CTW into bio-oil, while Tween 80 was more conducive to the development of pseudo-lignin, which endowed hydrochars higher energy density and updated the fuel quality and combustion behavior. Therefore, the research presented an effective method to convert CTW to clean solid fuel through the HTC treatment combining with surfactants.

Abstract
Background Hyperlipidemia has been hypothesized as a risk factor for thyroid cancer. However, the association between hypercholesterolemia and thyroid cancer is unclear, especially in Chinese population without available published data. We conducted this study to investigate the relationship between hypercholesterolemia and differentiated thyroid cancer (DTC) in Chinese population. Methods Three thousand seven hundred forty-eight patients were enrolled in the study, including 2,021 DTC patients and 1,727 benign subjects with benign thyroid nodules. Demographic characteristics, medical history, and clinical hematological examination were collected. Stratified analyses of association between hypercholesterolemia and risk of DTC were done. Multivariable logistic regression models were used to estimate the association between hypercholesterolemia and the risk of thyroid nodules being malignant. This study protocol was approved by the ethics committee of Shandong Provincial Qianfoshan Hospital and assigned in ClinicalTrials.gov protocol registration and results system (NCT03006289, https://clinicaltrials.gov/ct2/show/NCT03006289). Results The level of serum total cholesterol in patients with DTC is higher than that in benign subjects (P < 0.001). After adjusting hypercholesterolemia, age (P < 0.001), triglyceride (P = 0.003), and thyroid stimulating hormone (TSH) (P < 0.001) are found to be confounding factors. The risk of DTC in patients younger than 45 years old is 2.08 times than that of patients older than 45 years old (odds ratio = 0.48, 95% CI (0.38, 0.61), P < 0.001). A high TSH level is highly associated with the increased risk of DTC (P < 0.001). The multivariable logistic regression analysis revealed that the absence of hypercholesterolemia could reduce the risk of thyroid nodules being malignant (odds ratio = −0.75, 95% CI (−1.39, −0.12), P = 0.02). Comparing to the higher level of serum total cholesterol (>5.7 mmol/L), the closer the serum total cholesterol level is to normal (3.17–5.7 mmol/L), the less the risk of thyroid nodules being malignant is, and this difference is statistically significant (odds ratio = −0.67, 95% CI (−1.31, −0.03), P = 0.040). However, this difference is not found in the group of patients with lower level of total cholesterol (<3.17 mmol/L, odds ratio = 0.43, 95% CI (−1.22, 2.09), P = 0.068), suggesting that hypocholesterolemia is not a protective factor in the risk of thyroid nodules being malignant. Conclusions Hypercholesterolemia is an associated factor for risk of DTC in Chinese population.

Abstract
Objective: To investigate the association between blood lead concentrations and cognition impairment among Chinese older adults aged 65 or over. Method: Data was collected in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study between 2017 and 2018. This study included 1 684 elderly aged 65 years and older. Information about demographic characteristics, socioeconomic factors, health status and cognitive function score of respondents were collected by questionnaire survey and physical examination. Venous blood of the subjects was collected to detect the blood lead concentration. Subjects were stratified into four groups (Q1-Q4) by quartile of blood lead concentration. Multivariate logistic regression model was used to analyze the association between blood lead concentration and cognitive impairment. The linear or non-linear association between blood lead concentration and cognitive impairment were described by restrictive cubic splines (RCS). Results: Among the 1 684 respondents, 843 (50.1%) were female and 191 (11.3%) suffered from cognition impairment. After adjusting for confounding factors, the OR value and 95%CI of cognition impairment was 1.05 (1.01-1.10) for every 10 μg/L increase in blood lead concentration in elderly; Compared with the elderly in Q1, the elderly with higher blood lead concentration had an increased risk of cognitive impairment. The OR value and 95%CI of Q2, Q3 and Q4 groups were 1.19 (0.69-2.05), 1.45 (0.84-2.51) and 1.92 (1.13-3.27), respectively. Conclusion: Higher blood lead concentration is associated with cognitive impairment among the elderly aged 65 years and older in 9 longevity areas in China.

Abstract
Objective: To investigate the association of blood oxidative stress level with hypertriglyceridemia in the elderly aged 65 years and older in China. Methods: A total of 2 393 participants aged 65 years and older were recruited in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study, during 2017 to 2018. Information on demographics characteristic, life style and health status were collected by questionnaire and physical examination, and venous blood was collected to detect the levels of blood oxidative stress and hypertriglyceridemia. The linear or non-linear association between oxidative stress and hypertriglyceridemia was described by restrictive cubic splines (RCS) fitting multiple linear regression model. The generalized linear mixed effect model was conducted to assess the association between oxidative stress and hypertriglyceridemia. Results: A total of 2 393 participants, mean age was 84.6 years, the youngest was 65 and the oldest was 112, the male was 47.9%(1 145/2 393), the triglyceride level was (1.4±0.8) mmol/L. The hypertriglyceridemia detection rate was 9.99%(239/2 393). The results of multiple linear regression model with restrictive cubic spline fitting showed that MDA level was linear association with triglyceride level; SOD level was nonlinear association with triglyceride level. MDA level had significantly association with hypertriglyceridemia, and the corresponding OR value was 1.063 (95%CI: 1.046,1.081) with 1 nmol/ml increment of blood MDA; SOD level had significantly association with hypertriglyceridemia, and the corresponding OR value was 0.986(95%CI: 0.983,0.989) with 1 U/ml increment of blood SOD. Conclusion: Among the elderly aged 65 and older in 9 longevity areas in China, MDA and SOD levels were associated with the risk of hypertriglyceridemia.

Abstract
Abstract
Background
Cardiac Resynchronization Therapy (CRT) is an important therapeutic treatment for chronic heart failure. However, even in carefully selected cases up to 40% of patient fail to respond. First-phase ejection fraction (EF1), the ejection fraction up to the time of maximal ventricular contraction, is a novel and more sensitive echocardiographic measure of early systolic function.
Purpose
We examined the value of EF1, to predict response to CRT and clinical outcomes after CRT.
Methods
We analysed echocardiograms from 197 patients who underwent CRT between 2009 and 2018 and were followed to determine clinical outcomes.
Results
Volumetric response rate (reduction in end-systolic volume ≥15%) was 92.3% vs. 12.1%, for those with EF1 in the highest vs. lowest tertiles (p<0.001). A cut-off value of 11.9% for EF1 had >85% sensitivity and specificity for prediction of response to CRT; on multivariate logistic regression analysis incorporating previously defined predictors, EF1 was the strongest predictor of response (OR: 1.563, 95% CI: 1.371–1.782, p<0.001) (table 1). EF1 was also the strongest predictor of a clinical composite score (OR: 1.115, 95% CI: 1.044–1.191, p=0.001). Improvement in EF1 at 6 months after CRT implantation (6.5±5.8% vs 1.8±4.3% in responders vs. non-responders, p<0.001) was the best predictor of heart failure re-hospitalization and death after median follow-up of 29.2 months (HR: 0.819, 95% CI:0.765–0.876, p<0.001).
Conclusion
EF1 is a promising marker to identify patients likely to respond to CRT and most likely provides a measure of myocardial viability that determines response.

Abstract
Egg-type ducks and meat-type ducks are predominantly commercial or indigenous and have been subjected to artificial directional selection. These two duck types differ substantially in body shape, production performance and reproductivity. However, the genetic changes associated with phenotypic differences remain unclear. Here, we compared the two duck types at the genomic and transcriptomic levels. We identified a large number of SNPs and genes in genomic divergent regions in terms of FST and θπ values. The corresponding genes were mainly enriched in embryonic development function and metabolic pathway. RNA-seq analysis also revealed differential gene expression in the liver and gonads. The differentially expressed genes were functionally associated with signal transmission and substance metabolism respectively. Furthermore, we found that seven genes were related to differentiation between the two types by both g genome and transcriptome analysis and were plausible candidate genes. These genes were annotated to GO categories of cell development and disease immunity. These findings will enable a better understanding of the artificial selection history of meat and egg ducks and provide a valuable resource for future research on the breeding of these two lineages.

Abstract
OBJECTIVE The aim of this study was to explore the effect of long non-coding ribonucleic acid (lncRNA) KCNQ1 overlapping transcript 1 (KCNQ1OT1) on fracture healing and its possible mechanism. PATIENTS AND METHODS Abnormal lncRNAs were compared between patients with delayed fracture healing and those with normal fracture healing using gene expression profiling method. LncRNA expression in patients was verified by quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). Subsequently, the model of tibial fracture was successfully established in rabbits. The effect of lncRNA KCNQ1OT1 expression on tibial fracture healing in rabbits was explored. Meanwhile, the effects of lncRNA KCNQ1OT1 on cell proliferation and apoptosis were investigated by knockdown and overexpression experiments with HC-a as a cell model. Furthermore, Western blotting was used to explore the expressions of proteins in signaling pathway affected by lncRNA KCNQ1OT1. RESULTS Gene expression profiling and qRT-PCR revealed that lncRNA KCNQ1OT1 was significantly down-regulated in bone tissues of patients with delayed fracture healing. Compared with the control group, knocking down lncRNA KCNQ1OT1 remarkably reduced the serum levels of alkaline phosphatase (ALP) and osteoprotegerin (OPG) in rabbits, and markedly decreased bone trabecular growth index (p<0.05). In HC-a cells, overexpression of lncRNA KCNQ1OT1 activated the Wnt/β-catenin signaling pathway, which could be suppressed by knocking down lncRNA KCNQ1OT1. Cell Counting Kit-8 (CCK-8) assay and 5(6)-carboxyfluorescein diacetate, succinimidyl ester (CFSE) results manifested that lncRNA KCNQ1OT1 remarkably promoted the proliferation and inhibited apoptosis of HC-a cells by activating the Wnt/β-catenin signaling pathway. CONCLUSIONS LncRNA KCNQ1OT1 plays a vital role in delayed fracture healing. Moreover, it can induce cell proliferation and inhibit cell apoptosis by activating the Wnt/β-catenin signaling pathway. Therefore, KCNQ1OT1 may be used as a biomarker to predict the occurrence of delayed fracture healing.

Abstract
Objective: To explore the risk factors for death in patients with pulmonary arterial hypertension related to congenital heart disease (PAH-CHD) and the clinical characteristics of different subtypes in patients with PAH-CHD. Methods: It was a retrospective study. A total of 507 PAH-CHD patients, who were hospitalized in the Department of Pediatric Cardiology of Beijing Anzhen Hospital between September 2005 and May 2019, were included. Patients were divided into 4 subgroups: (1) Eisenmenger syndrome(ES) group. (2) PAH associated with prevalent systemic-to-pulmonary shunts(SP) group. (3) PAH associated with small defects(SD) group. (4) PAH after defect correction(CD) group. According to the complexity of cardiac malformation, patients were divided into simple-medium complex malformation group and complex malformation group. According to the location of shunts, patients were divided into pre-tricuspid group, post-tricuspid group, and mixed group or complex deformity group. Baseline clinical data of patients were collected from the electronic medical record system. Demographic data (age, gender, etc.), percutaneous oxygen saturation(SPO(2)), New York Heart Association(NYHA) cardiac function classification, 6 minutes walking distance(6MWD), and B type natriuretic peptide(BNP), systolic pulmonary arterial pressure(sPAP) estimated by echocardiography and mean pulmonary artery pressure (mPAP), mean right atrial pressure(mRAP), cardiac index(CI), and calculated pulmonary vascular resistance (PVR) estimated by right heart catheterization were compared among various groups. The results of regular follow-up of all enrolled patients were collected, including the status of monotherapy or combination of PAH-targeted drugs during the follow-up period, cardiac-related adverse events(hemopysis, syncope, edema, arrhythmia, etc.) and primary endpoint event(all-cause death) were obtained and analyzed. Risk factors for all-cause death were analyzed using univariate and multivariate Cox regression analysis model. Results: The median age at diagnosis was 23.1(13.9,32.1) years, 345 cases(68.0%) were female. Two hunderds and thirty-five cases(46.4%) were diagnosed with ES; 193 cases(38.1%) were diagnosed with CD, 47 cases (9.3%) were diagnosed with SD. Among them, 32 cases(6.3%) were in the SP group. All 507 patients underwent echocardiography examination, there were significant differences in sPAP among different clinical subgroups(P<0.001). A total of 289 patients(57.0%) received right heart catheterization examination, the results showed that the ES group had the highest mPAP and PVR and the lowest mRAP(all P<0.001), the CD group had the highest mRAP and CI(both P<0.001). The 6MWD in the ES group was significantly shorter than that in the SP, SD, and CD groups(all P<0.001). The proportion of patients with NYHA class Ⅲ/Ⅳ was higher in SD group than in SP group(P<0.001), which was similar between SD, ES and CD groups (P values were 0.077 and 0.072, respectively). At admission, the proportion of patients with NYHA class Ⅰ/Ⅱwas the highest in SP group(96.9% (31/32) ), followed by CD group (85.5%(165/193)) and the ES group(85.1%(200/235)), and the SD group(75.0%(35/47)). The BNP level at admission was also higher in SD group than in SP, ES and CD groups(P<0.001). Of the 507 patients, 379(74.8%) patients received PAH-targeted drug therapy at the last follow-up, and the treatment plan was mainly monotherapy(75.7%(287/379)). The median follow-up time was 3.6(2.0, 5.6) years and 37(7.3%) patients died, including 13 in the CD group, 17 in the ES group, and 7 in the SD group. No deaths occurred in the SP group. Right heart failure was the most common cause of death(11(29.7%)), followed by severe hemoptysis dyspnea(7(18.9%)), sudden cardiac death(6(16.2%)), and pulmonary hypertensive crisis(4(10.8%)). Kaplan-Meier curve showed that survival rates of end-point-free events at 1, 3, 5 and 10 years after diagnosis of PAH were 98.0%, 95.4%, 89.9%, and 84.4%, respectively; there were statistically significant differences in survival among the subgroups(P=0.026); there was no significant difference in the survival rate between the ES group and the CD group(P=0.918), and both were higher than the SD group(P values were 0.011 and 0.013, respectively). Univariate Cox regression analysis showed that NYHA class Ⅲ/Ⅳ and BNP>100 ng/L at admission were the risk factors for all-cause death in patients with PAH-CHD(HR=6.452, 95%CI 3.378-12.346, P<0.001, and HR=2.481, 95%CI 1.225-5.025, P=0.012). Multivariate Cox regression analysis showed that NYHA class Ⅲ/Ⅳ was an independent risk factor for all-cause death in patients with PAH-CHD(HR=4.998, 95%CI 1.246-20.055, P=0.023). Conclusions: PAH-CHD patients with different clinical subtypes have different clinical symptoms, cardiac functional class, hemodynamic characteristics, and mid to long-term survival rates. SP patients have the best prognosis, outcome of ES and CD patients is similar, and SD patients have the worst prognosis. NYHA class Ⅲ/Ⅳ is an independent risk factor for all-cause death in patients with PAH-CHD.

The top 3 types of rare diseases were "diseases of blood and blood-forming organs and certain disorders involving immune mechanism" (32.81%, 8 001/24 388), "congenital malformations, deformations and chromosomal abnormalities" (24.87%, 6 065/24 388) and "diseases of the nervous system" (19.01%, 4 635/24 388). The number of rare disease cases increased year by year from 2007 to 2017 with an average annual growth of 19.69%, however, the proportion of rare disease cases in the annual number of hospitalized cases only showed upward trend during 2016-2017, the time distribution of different types of rare diseases had different characteristics. The male to female ratio of rare diseases cases was 1.35∶1(13 990/10 398), "diseases of the digestive system" (4.45∶1, 1 180/265), "consequences of injury, poisoning and other external causes" (3.51∶1, 281/80) and "diseases of the nervous system" (2.26∶1, 3 213/1 422) had the highest male to female ratio. The distributions of rare disease types and diseases of different types in different age groups varied. The top 10 rare diseases accounted for 53.55% (13 060/24 388) of the total cases, and the top 3 diseases were adult idiopathic neutropenia (14.41%, 3 515/24 388), corticobasal degeneration (7.60%, 1 854/24 388) and henock-schoenlein purpura (6.01%, 1 466/24 388). Conclusion: The analysis on the characteristics of 24 388 rare disease cases in Zhejiang during 2007-2017 provided reference evidence for the promotion of rare disease research, monitoring, building registration database, and development of the prevention and control strategy for rare diseases in China.

Abstract
WSL8 encoding a deoxyribonucleoside kinase (dNK) that catalyzes the first step in the salvage pathway of nucleotide synthesis plays an important role in early chloroplast development in rice. The chloroplast is an organelle that converts light energy into chemical energy; therefore, the normal differentiation and development of chloroplast are pivotal for plant survival. Deoxyribonucleoside kinases (dNKs) play an important role in the salvage pathway of nucleotides. However, the relationship between dNKs and chloroplast development remains elusive. Here, we identified a white stripe leaf 8 (wsl8) mutant that exhibited a white stripe leaf phenotype at seedling stage (before the four-leaf stage). The mutant showed a significantly lower chlorophyll content and defective chloroplast morphology, whereas higher reactive oxygen species than the wild type. As the leaf developed, the chlorotic mutant plants gradually turned green, accompanied by the restoration in chlorophyll accumulation and chloroplast ultrastructure. Map-based cloning revealed that WSL8 encodes a dNK on chromosome 5. Compared with the wild type, a C-to-G single base substitution occurred in the wsl8 mutant, which caused a missense mutation (Leu 349 Val) and significantly reduced dNK enzyme activity. A subcellular localization experiment showed the WSL8 protein was targeted in the chloroplast and its transcripts were expressed in various tissues, with more abundance in young leaves and nodes. Ribosome and RNA-sequencing analysis indicated that some components and genes related to ribosome biosynthesis were down-regulated in the mutant. An exogenous feeding experiment suggested that the WSL8 performed the enzymic activity of thymidine kinase, especially functioning in the salvage synthesis of thymidine monophosphate. Our results highlight that the salvage pathway mediated by the dNK is essential for early chloroplast development in rice.

Aims
First-phase ejection fraction (EF1), the ejection fraction up to the time of maximal ventricular contraction may be impaired in heart failure with preserved ejection fraction (HFpEF), with homeostatic mechanisms preserving the overall ejection fraction. We examined whether EF1 is impaired and whether it predicts adverse outcomes in patients with HFpEF.
Methods and Results
We examined EF1 in patients with HFpEF diagnosed according to European Society of Cardiology guidelines, in subjects with pre-clinical diastolic dysfunction and in control subjects with no evidence of heart failure. The predictive value of EF1 for a combined end-point of re-hospitalisation for heart failure and death from any cause was compared to that of conventional echocardiographic and other indices. There was a progressive impairment of EF1 in patients with diastolic dysfunction and HFpEF compared to those without evidence of heart failure (P < 0.001). In 180 HFpEF patients followed for a median of 14.7 months, 101 patients reached the primary endpoint (61 deaths and 40 hospitalisations). EF1 was the most powerful predictor of events (table 1). A cut-off value of 19.4% gave hazard ratios (for EF1 < 19.4% compared to ≥19.4%) of 3.04 (figure 1), (95% confidence interval 2.014 – 4.604, P < 0.001) unadjusted, and 2.976 (1.887 – 4.695, P < 0.001) adjusted for age, gender, other echocardiographic indices (including EF, E/e’ ratio, stroke volume and left atrial volume index) and N-terminal pro-brain natriuretic peptide.
Conclusion
Early systolic function is impaired in HFpEF and is a powerful predictor of clinical outcomes. Therapies targeted at improving early systolic function may improve outcomes in HFpEF.

Abstract
OBJECTIVE Previous study has reported that miR-330-3p was highly expressed in breast cancer (BC) patients. However, the effect of miR-330-3p in BC progression remains largely unclear. The purpose of this study was to investigate the clinical significance of miR-330-3p expression in BC. PATIENTS AND METHODS The expression of miR-330-3p was detected by quantitative Real-time PCR in BC tissues and matched normal breast tissues. The association of miR-330-3p expression with clinicopathological factors of BC patients was also analyzed by x2-test. Prognosis value of patients with BC was assessed by Kaplan-Meier method and Cox proportional hazards model, respectively. RESULTS Quantitative real-time PCR analysis showed that the expression level of miR-330-3p was significantly higher in BC specimens than that in corresponding noncancerous tissues (p < 0.01). The levels of miR-330-3p were positively correlated with the status of TNM stage (p = 0.011) and lymph node metastasis (p = 0.006). Kaplan-Meier analysis revealed that 5-year overall survival of BC patients with high miR-330-3p expression was shorter compared to those patients with low miR-330-3p expression (p < 0.0001). Moreover, univariate and multivariate regression analysis demonstrated that miR-330-3p was an independent prognostic factor in BC. CONCLUSIONS Our data suggest that miR-330-3p upregulation maybe concurrently associated with prognosis in patients with BC, suggesting that miR-330-3p may be a potential prognostic biomarker and therapeutic target for patients with BC.

Abstract
Hearing loss is one of the most common sensory disorders worldwide, and about half of all occurrences are attributable to genetic factors. Here, we have identified a novel pathogenic variant in HOMER2 in a Chinese family with autosomal dominant, non-syndromic hearing loss. This is the second family reported globally with hearing loss caused by a variant in HOMER2. The pathogenic variant c.840_841insC in HOMER2 (NM_199330), segregating with the hearing-loss phenotype in the family, leads to a premature stop codon producing a truncated protein. The coiled-coil domain in the C-terminal of HOMER2 protein is essential for protein multimerization and HOMER2-CDC42 interaction. We compared the phenotypes in the two families and found that hearing impairment in this Chinese family was more severe. Furthermore, we found that the ability of this insertion mutant type HOMER2 (HOMER2MU ) to multimerize decreased more significantly than wild-type HOMER2 (HOMER2WT ) and the reported c.554G>C (NM_004839) mutant HOMER2. HOMER2MU protein tended to be distributed in a diffuse manner, whereas HOMER2WT and the reported mutant HOMER2 tended to cluster together. Our research provides a validating second family for variants in HOMER2 causing non-syndromic sensorineural hearing loss. HOMER2 homo-/hetero-multimerization might be the first step in exerting its normal function.

Abstract
A concise formal synthesis of ecteinascidin 743 is described. Key features involve the coupling of the multisubstituted tetrahydroisoquinoline and phenylalaninol moieties via a regio- and stereoselective Pictet-Spengler cyclization as well as the subsequent chemoselective MOM protection of the phenol group, which opens a rapid access to the desirable pentacycle. The synthesis successfully delivered the advanced intermediate with the characteristic macrolactone from sesamol in 23 steps.
