An 11-day-old female neonate was admitted for cough with mouth foaming and feeding difficulties. The laboratory results indicated hyperlactatemia, elevated markers of myocardial injury and inflammation, and high levels of acylcarnitine octanoylcarnitine and decanoylcarnitine in tandem mass spectrometry. Ultrasonography and MRI suggested cardiac insufficiency and hypertrophic cardiomyopathy. Whole exome sequencing showed that both the proband and her elderly sister had a compound heterozygous variant of c.1492dup (p.T498Nfs*13) and c.1376T>C (p.F459S) in the ATAD3A gene, inherited from their father and mother, respectively. The diagnosis of Harel-Yoon syndrome was confirmed. The proband and her sister were born with clinical manifestations of metabolic acidosis, hyperlactatemia, feeding difficulties, elevated markers of myocardial injury as well as cardiac insufficiency, and both died in early infancy.

Objective: To investigate the association between the urinary arsenic level and serum total testosterone in Chinese men aged 18 to 79 years. Methods: A total of 5 048 male participants aged 18 to 79 years were recruited from the China National Human Biomonitoring (CNHBM) from 2017 to 2018. Questionnaires and physical examinations were used to collect information on demographic characteristics, lifestyle, food intake frequency and health status. Venous blood and urine samples were collected to detect the level of serum total testosterone, urinary arsenic and urinary creatinine. Participants were divided into three groups (low, middle, and high) based on the tertiles of creatinine-adjusted urinary arsenic concentration. Weighted multiple linear regression was fitted to analyze the association of urinary arsenic with serum total testosterone. Results: The weighted average age of 5 048 Chinese men was (46.72±0.40) years. Geometric mean concentration (95%CI) of urinary arsenic, creatinine-adjusted urinary arsenic and serum testosterone was 22.46 (20.08, 25.12) μg/L, 19.36 (16.92, 22.15) μg/g·Cr and 18.13 (17.42, 18.85) nmol/L, respectively. After controlling for covariates, compared with the low-level urinary arsenic group, the testosterone level of the participants in the middle-level group and the high-level group decreased gradually. The percentile ratio (95%CI) was -5.17% (-13.14%, 3.54%) and -10.33% (-15.68%, -4.63). The subgroup analysis showed that the association between the urinary arsenic level and testosterone level was more obvious in the group with BMI<24 kg/m² group (P_interaction=0.023). Conclusion: There is a negative association between the urinary arsenic level and serum total testosterone in Chinese men aged 18 to 79 years.

BackgroundHome-based intervention occupies a prominent place in the treatment of autism spectrum disorder （ASD） in children， whereas previous studies on the effect of home-based early intensive behavioral intervention on verbal ability of children with ASD are somewhat inadequate. ObjectiveTo study the effects of intensive family behavioral of intervention based on Verbal Behavior Milestones Assessment and Placement Program （VB-MAPP） on the language ability of children with ASD， so as to provide references for the development of family intervention strategies for children with ASD. MethodsChildren aged 2 to 3 years old who attended the Children's Rehabilitation Department of the Second Affiliated Hospital of Shantou University Medical College from September 2020 to December 2021 and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria for ASD were selected as the study objects. A non-randomized concurrent control trial was conducted to compare a study group （n=24） receiving home-based early intensive behavioral intervention using VB-MAPP with a control group （n=14） receiving training from other special institutions or early childhood education institutions. The intervention lasted for 6 months in both groups. Before and after the intervention， the VB-MAPP milestone assessment was performed in the two groups， and the VB-MAPP milestone score， mand， trac and listener responds were selected as the study indicators. Then the intervention effect was compared between two groups， and the multiple linear regression was performed to screen the related influencing factors. ResultsAfter intervention， the total milestone assessment score， mand， tact and listener responds scores of study group were higher than those of control group， with statistical difference （Z=-4.339~-2.195， P<0.05 or 0.01）. Multiple linear regression analysis denoted that the average weekly hours of home-based intervention in the first three months had certain effect on listener responds （β=1.029， P<0.05）. ConclusionApplication of home-based early intensive behavior intervention using VB-MAPP may contribute to the improvement of verbal abilities such as mand， tact and listener responds in children with ASD. ［Funded by 2020 Guangdong Provincial Science and Technology Innovation Strategy Special Fund （number， 20200601）］

Objective: To investigate the predictive value of glycosylated hemoglobin A1c/apolipoprotein A-1 (HbA1c/ApoA-1) ratio for major adverse cardiovascular events (MACEs) in patients with acute coronary syndrome (ACS). Methods: The present study is a retrospective cohort study. ACS patients who were hospitalized and underwent coronary angiography at Beijing Hospital from March 2017 to March 2019 were enrolled. Baseline information such as sex, age, previous history, Gensini score, HbA1c and ApoA-1 were analyzed. Patients were divided into two groups according to presence or absence of MACEs and the difference on HbA1c/ApoA-1 ratio was compared between the two groups. According to the tertiles of HbA1c/ApoA-1 levels, patients were divided into high (5.87-16.12), medium (4.50-5.83) and low (2.11-4.48) HbA1c/ApoA-1 groups. Cox proportional risk model was used to evaluate the differences in MACEs and all-cause mortality among the three groups. Kaplan-Meier survival analysis was used to compare the differences of MACEs between the various HbA1c/ApoA-1 groups. Results: A total of 366 ACS patients were included in this study. The mean age of the patients was (65.9±10.3) years. There were 59 MACEs and 10 all-cause deaths during the mean of (22.3±4.4) months follow-up. After adjusting for age, systolic blood pressure, history of diabetes and Gensini score, the incidence of MACEs was 2.45 times higher in the high HbA1c/ApoA-1 group than in the low HbA1c/ApoA-1 group (95%CI 1.16-5.18, P=0.019). There was no significant difference in all-cause mortality between the high and low HbA1c/ApoA-1 groups (P=1.000). Kaplan-Meier survival analysis showed that patients in the high HbA1c/ApoA-1 group had the highest risk of MACEs, while patients in the low HbA1c/ApoA-1 group had the lowest risk of MACEs (P<0.01). Spearman rank correlation analysis showed that HbA1/ApoA-1 ratio was positively correlated with Gensini score in ACS patients (r=0.274, P<0.01). Conclusion: High HbA1c/ApoA-1 ratio was an independent risk factor for MACEs in ACS patients. Patients with high HbA1c/ApoA-1 ratio had more severe coronary artery disease lesions. HbA1c/ApoA-1 ratio may be used as a potential risk stratification biomarker for ACS patients, it might be useful for the early identification of high-risk population and for predicting the incidence of MACEs among ACS patients.

To explore the changes and the reaction mechanisms between soil microecological environment and the content of secon-dary metabolites of plants under water deficit, this study carried out a pot experiment on the 3-leaf stage seedlings of Rheum officinale to analyze their response mechanism under different drought gradients(normal water supply, mild, moderate, and severe drought). The results indicated that the content of flavonoids, phenols, terpenoids, and alkaloids in the root of R. officinale varied greatly under drought stresses. Under mild drought stress, the content of substances mentioned above was comparatively high, and the content of rutin, emodin, gallic acid, and(+)-catechin hydrate in the root significantly increased. The content of rutin, emodin, and gallic acid under severe drought stress was significantly lower than that under normal water supply. The number of species, Shannon diversity index, richness index, and Simpson index of bacteria in the rhizosphere soil were significantly higher than those in blank soil, and the number of microbial species and richness index decreased significantly with the aggravation of drought stresses. In the context of water deficit, Cyanophyta, Firmicutes, Actinobacteria, Chloroflexi, Gemmatimonadetes, Streptomyces, and Actinomyces were the dominant bacteria in the rhizosphere of R. officinale. The relative content of rutin and emodin in the root of R. officinale was positively correlated with the relative abundance of Cyanophyta and Firmicutes, and the relative content of(+)-catechin hydrate and(-)-epicatechin gallate was positively correlated with the relative abundance of Bacteroidetes and Firmicutes. In conclusion, appropriate drought stress can increase the content of secondary metabolites of R. officinale from physiological induction and the increase in the association with beneficial microbe.

OBJECTIVE: To analyze the preservation effect and related influencing factors of human peripheral blood mononuclear cells under serum-free condition at 4 ℃. METHODS: Human peripheral blood mononuclear cells were isolated by density gradient centrifugation, and stored at 4 ℃ under different cell concentrations, supplemented with human serum albumin, and glucose. The cell viability, total cell number, viable cell number and cell phenotype were detected during preservation of 72 h. RESULTS: With the prolongation of storage time, the number of human peripheral blood mononuclear cells gradually decreased(r=0.982). Compared with the cell concentration of (5-6)×10⁶ cells/ml, the cell number decreased more slowly when the cell storage concentration was (1-2)×10⁶ cells/ml; Adding human serum albumin and glucose can effectively improve the survival rate of human peripheral blood mononuclear cells, among which 2% human serum albumin has a better preservation effect; Compared with the blank control group, the analysis results of cell subsets showed that the downward trends of NK cells and T cells were significantly slowed after adding albumin and glucose. CONCLUSION The cell density of (1-2)×10⁶/ml and 2% human serum albumin are more suitable for the preservation of PBMC, and 5% glucose can improve the preservation effect of human peripheral blood mononuclear cells at 4 ℃.

Glioblastoma is carcinogenesis of glial cells in central nervous system and has the highest incidence among primary brain tumors. Brain metastasis, such as breast cancer and lung cancer, also leads to high mortality. The available medicines are limited due to blood-brain barrier. Abnormal activation of phosphatidylinositol 3-kinases (PI3K) signaling pathway is prevalent in glioblastoma and metastatic tumors. Here, we characterized a 2-amino-4-methylquinazoline derivative XH30 as a potent PI3K inhibitor with excellent anti-tumor activity against human glioblastoma. XH30 significantly repressed the proliferation of various brain cancer cells and decreased the phosphorylation of key proteins of PI3K signaling pathway, induced cell cycle arrest in G1 phase as well. Additionally, XH30 inhibited the migration of glioma cells and blocked the activation of PI3K pathway by interleukin-17A (IL-17A), which increased the migration of U87MG. Oral administration of XH30 significantly suppressed the tumor growth in both subcutaneous and orthotopic tumor models. XH30 also repressed tumor growth in brain metastasis models of lung cancers. Moreover, XH30 reduced IL-17A and its receptor IL-17RA in vivo. These results indicate that XH30 might be a potential therapeutic drug candidate for glioblastoma migration and brain metastasis.

OBJECTIVE: To analyze the epidemiological characteristics of pneumoconiosis among migrant workers without liability subject(hereinafter referred to as Pneumoconiosis without Liability Subject) in Hunan Province. METHODS: The cases of pneumoconiosis without liability subject from 2017 to 2019 in Hunan Province were selected as the research subjects using typical sampling method. They were clinical diagnosis by occupational disease diagnostic institutions. The distributions of age, gender, length of service, area, type of work, type of pneumoconiosis, pneumoconiosis stage and the situation of poor households with filing and registration card were analyzed. RESULTS: A total of 18 870 cases of pneumoconiosis without liability subject were clinically diagnosed in Hunan Province from 2017 to 2019. The patients were mainly males(accounting for 99.8%), with the age ranged 50-65 years old(64.7%). Most of them had dust exposure service length of 5-29 years(78.4%). The cases of stage Ⅰ, Ⅱ and Ⅲ pneumoconiosis accounted for 32.2%, 26.0% and 41.8% respectively. The main types of disease were coal workers′ pneumoconiosis and silicosis(accounted for 99.3%). The first five geographical distributions were Chenzhou City, Zhuzhou City, Hengyang City, Yiyang City and Shaoyang City, accounting for 17.9%, 14.6%, 14.1%, 11.8% and 9.2% respectively. The distribution of work types were mainly mine-related jobs(91.3%). There were 1 774 cases who had complications(9.4%), of which the top three complications were emphysema, pulmonary and bronchial infection and tuberculosis. There were 3 662 cases with poor households archives and cards(19.4%). CONCLUSION: The hazards of pneumoconiosis among migrant workers in Hunan Province should not be ignored. In 2017, Hunan Province took the lead in launching a large-scale basic medical treatment and rescue operation for migrant workers with pneumoconiosis, which helped solve the problem of pneumoconiosis in migrant workers who had no professional history certification and responsible employer.

Objective: To explore the association between inflammation activity of left atrial epicardial adipose tissue (LA-EAT) measured by ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG PET/CT) and atrial fibrillation (AF). Methods: A total of 78 patients with AF, who underwent ¹⁸F-FDG PET/CT in the Nuclear Medicine Department of the Third Affiliated Hospital of Soochow University due to abnormally elevated levels of tumor indicators or malignant tumors from March 2018 to December 2019, were enrolled in this retrospective study. According to the examination date of PET/CT and basic characteristics of AF patients (gender, age), a 1∶1 propensity score matching was used to enroll a non-AF control group (78 patients). The maximum standard uptake value of left atrial epicardial tissue (LA-EAT FDG SUV_max) and total EAT volume (V-EAT) were measured by ¹⁸F-FDG PET/CT. Left ventricular ejection fraction (LVEF) and left atrial diameter (LAD) were obtained by echocardiography. Blood lipids and biomarkers of inflammation were measured. The differences of clinical data and EAT-related indicators were compared between the AF group and control group. Logistic multivariate regression analysis was used to determine the related factors of AF. Then the receiver operating characteristic (ROC) curve was used to determine the cutoff value of LA-EAT FDG SUV_max on the diagnosis of AF. Univariate and multivariate logistic regression analysis were used to analyze the relationship between the increase of LA-EAT FDG SUV_max and AF. Results: The age was (66.9±10.2) years and there were 55 males (70.5%) in the AF group. The age was (66.9±8.0) years, and there were 52 males (66.7%) in the control group (both P>0.05). The LAD ((44.2±5.8) mm vs. (35.4±4.4) mm), V-EAT ((122.1±42.0) cm³ vs. (91.6±34.5) cm³), and LA-EAT FDG SUV_max ((1.6±0.3) vs. (1.4±0.2)) values were significantly higher, while LVEF ((60.1±4.7)% vs. (63.9±2.9)%) was lower in the AF group than in the control group (P all<0.001). Multivariate logistic regression analysis showed that LAD (OR=1.340, 95%CI 1.195-1.502), V-EAT (OR=1.016, 95%CI 1.001-1.031), and LA-EAT FDG SUV_max (OR=1.375, 95%CI 1.095-1.723) were positively correlated with AF, LVEF (OR=0.781, 95%CI 0.659-0.926) was negatively correlated with AF(P all<0.05). The area under the ROC curve of LA-EAT FDG SUV_max for diagnosis of AF was 0.680 (95%CI 0.597-0.764, P<0.001), and the best cut-off value was 1.415 with a sensitivity of 65.4% and specificity of 61.5%. After adjusting for high-density lipoprotein cholesterol, LVEF, LAD and V-EAT, LA-EAT FDG SUV_max≥1.415 was independently associated with AF (OR=2.982, 95%CI 1.122-7.926, P=0.010). Conclusions: The inflammatory activity of LA-EAT measured by ¹⁸F-FDG PET/CT is an independent risk factor of AF, and the increased inflammatory activity of LA-EAT is positively correlated with AF.

Objective: To determine the prevalence and determinants of folic acid (FA) supplementation in Chinese couples planning for pregnancy and in women during early pregnancy. Methods: This was a cross-sectional study based on the Shanghai PreConception Cohort (SPCC) study. Data on FA supplementation and socio-demographic features were collected using questionnaires. Couples visiting clinics for pre-pregnancy examination and pregnant women at < 14 gestational weeks were recruited in Shanghai, China, between March 2016 and September 2018. Results: Among the pregnancy planners, 42.4% (4,710/11,099) women and 17.1% (1,377/8,045) men used FA supplements, while 93.4% (14,585/15,615) of the pregnant women used FA supplements. FA supplement use was higher in female pregnancy planners who were older ( : 1.13, 95% : 1.08-1.18), had higher education ( : 1.71, 95% : 1.53-1.92), and were residing in urban districts ( : 1.06, 95% : 1.01-1.11) of FA supplementation; female pregnancy planners with alcohol consumption ( : 0.95, 95% : 0.90-0.99) had lower odds of FA supplementation. In early pregnancy, women with higher educational level ( : 1.04, 95% : 1.03-1.06), who underwent pre-pregnancy examination ( : 1.02, 95% : 1.01-1.03) had higher odds of using an FA supplement; older aged ( : 0.99, 95% : 0.98-0.99), and multigravida ( : 0.97, 95% : 0.96-0.98) had lower odds of FA supplementation. Conclusion Although the majority of pregnant women took FA supplements, more than half of the women planning for pregnancy did not. Urgent strategies are needed to improve pre-conception FA supplementation.
