ABSTRACT

Childhood-onset schizophrenia (COS) is an unusual severe neurodevelopmental disorder of unknown etiology. In this study, we aimed to survey the missense variants in new cases of COS and also identify possible pathology biomarkers for COS. We found one list of mutated genes such as TTN, MUC12, and MUC2, which are the candidates to be involved in the etiology of COS. Next, we used WGSNA to predict COS disease-related genes and identified differential DNA methylation among COS disease groups, COS dangerous groups, and normal groups and found eight methylation sites that can be used as the diagnostic biomarkers. A total of six key genes are obtained through the intersection analysis between weighted correlation network analysis (WGCNA) mode, methylation-related genes, and differentially expressed genes (DGenes). These genes may play important roles in the progression of COS and serve as the potential biomarkers for future diagnosis. Our results might help to design the molecule or gene-targeted drugs for COS.

ABSTRACT

Based on the collected urban motor vehicle activity ownership and traffic flow of highways, combined with the mileage and source profiles of VOCs, using the emission factor method, we established high-resolution emission inventories from 2016 to 2019 for urban and 2016-based highway motor vehicles, respectively, in Henan Province, China. The results showed that gasoline vehicles, particularly minibuses and ordinary motorcycles, were the main contributors of CO, VOCs, and NH3, whereas heavy-duty and light-duty diesel trucks emitted SO2, NOx, and PM. Vehicles with China 1, China 3, and China 4 emission standards contributed significantly to pollutant emissions in the fleet. The temporal variation in traffic flow was consistent with the changes in freight and passenger traffic, with higher coefficients of variation for highways from August to October and the lowest in November. The weekly and daily changes in urban trunk roads showed distinct weekend effects and clear double-peak features, respectively. High-value emission areas were concentrated in urban centers with dense transport networks and high traffic volumes and on roads radiating outward from urban areas. The Lianhuo Expressway and the Beijing-Hong Kong-Macau Expressway were high-emission roads. Light-duty gasoline vehicles made the largest contribution to the ozone formation potential (OFP) of VOCs from motor vehicles. Five species, such as ethylene and propylene, contributed significantly to VOC emissions and OFP. The average annual growth rate of vehicle ownership from 2016 to 2019 was 5.7%. Compared with 2016, VOC emissions increased by 2.8% in 2019, whereas emissions of other pollutants showed decreasing trends of different degrees, with decreases of 76.3%, 51.7%, 50.3%, 43.1%, 16.7%, and 5.9% for SO2, PM2.5, PM10, NH3, CO, and NOx, respectively. The emission reduction percentage of each pollutant in 2019 under the control policies relative to the baseline scenario ranged from 15.6% to 82.4%.

ABSTRACT

OBJECTIVE: To study the changes in metabolic markers and clinical outcome after treatment with different drug regimens in children with bipolar affective disorder. METHODS: A retrospective analysis was performed on the medical data of 220 children with bipolar affective disorder who attended the hospital from January 2017 to January 2020. According to the treatment method, 112 children treated with atypical antipsychotic drugs alone were enrolled as the control group, and 108 children treated with atypical antipsychotic drugs combined with mood stabilizer were enrolled as the study group. The two groups were compared in terms of baseline data, changes in related metabolic markers[fasting insulin (FIN), glycosylated hemoglobin (HbAlc), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C)] after treatment, incidence rate of metabolic syndrome, and clinical outcome. RESULTS: There were no significant differences in the baseline data including age, sex, and course of disease between the two groups (P > 0.05). The study group had a significantly higher overall response than the control group (92.6% vs 82.1%, P < 0.05). Before treatment, there were no significant differences in the levels of FIN and HbAlc between the two groups (P > 0.05). After treatment, the control group had a significant increase in the level of FIN and a significantly higher level of FIN than the study group (P < 0.05). The study group showed no significant change in the level of FIN after treatment (P > 0.05). There was no significant difference in the level of HbAlc between the two groups before and after treatment (P > 0.05). Before treatment, there were no significant differences in the levels of TC, TG, HDL-C, and LDL-C between the two groups (P > 0.05), and after treatment, the control group had significant increases in TC and TG and significantly higher levels of TC and TG than the study group (P < 0.05). The study group showed no significant changes in TC and TG after treatment (P > 0.05). There were no significant differences in the levels of HDL-C and LDL-C between the two groups before and after treatment (P > 0.05). The study group had a significantly lower incidence rate of metabolic syndrome than the control group (2.8% vs 9.8%, P < 0.05). CONCLUSIONS: Atypical antipsychotic drugs combined with mood stabilizer in the treatment of bipolar disorder in children have little effect on the level of metabolic markers, and the curative effect is significant.

ABSTRACT

PURPOSE: Children who are left behind when their parents migrate for work have a high prevalence of emotional and behavioral problems, which affect social function and increase family burden. To date, no national survey has been conducted on the emotional and behavioral problems of left-behind children (LBC) in China. This study aimed to investigate the emotional and behavioral outcomes of primary school LBC in the fourth grade in impoverished rural China and the possible influences of family environment and parenting practices. METHODS: A cross-sectional study was carried out in 27 rural counties in the central and western parts of China from November 2016 to January 2017. The method of quota sampling was adopted to achieve a representative sample using postweighting adjustment. The survey sample was distributed proportionately across each county. LBC were defined as children aged <16 years who had two parents leave home to work or one parent leave home while the other lost the capacity to rear their children. The term "non-left-behind children" (NLBC) refers to children who have at least one parent who has not migrated for work. The Strengths and Difficulty Questionnaire (SDQ) was applied to measure children's emotional and behavioral problems. RESULTS: After the weighted calculations were performed, there were 1,147 LBC and 3,953 NLBC. The proportion of abnormal SDQ total scores (>17) was significantly higher in the LBC group than in the NLBC group (15.6% vs. 11.6%; p < .01). Binary regression analysis showed that high levels of insomnia (odds ratio [OR] 1.54, 95% confidence interval [CI] 1.04-2.27), loneliness (OR 1.65, 95% CI 1.13-2.43), and self-harm (OR 1.92, 95% CI 1.17-3.16) may increase the risk of abnormal SDQ total scores in LBC. CONCLUSIONS: LBC showed a higher prevalence of abnormal SDQ total scores than NLBC. Insomnia, loneliness, and self-harm behavior were associated with abnormal SDQ total scores in LBC.

ABSTRACT

The spatio-temporal characteristics of ozone (O3) pollution in the Henan Province in 2017 and its relationship with particulate matter, precursors, and meteorological factors were studied using the data obtained from the air quality monitoring station and national baseline ground climate station. Results showed that the annual mean O3 concentration of a maximum daily 8-h average (MDA8) was 108 µg·m-3 in the Henan Province with the trend of summer > spring > autumn > winter. Different levels of O3 were observed in various cities. The number of days exceeding the standard was up to 88 days in Anyang, while the lowest was found in Xinyang with 17 days. The most severe of O3 pollution occurred during late spring and early summer. During this period, the average monthly concentration of O3 MDA8 was above 140 µg·m-3, and peaked in June. The qualitative and quantitative analysis showed that the monthly average concentration of O3 MDA8 was negatively correlated with particulate matter, and the O3 hourly concentration was also negatively correlated with CO and NO2. The O3 MDA8 concentration and meteorological factors (sunshine duration, temperature, rainfall, visibility, humidity, and wind speed) had different correlations during different seasons and various cities.

ABSTRACT

This study uses the national ambient air quality station data of Anyang City from 2014 to 2017 to analyze the characteristics and variation rules of ozone (O3) in different functional zones (urban, suburban, and industrial), and also studies meteorological influencing factors and potential source distributions of O3 pollution. The results showed that the O3 concentration in Anyang increased significantly between 2014 and 2017, whereby pollution started to advance from 2015 and the earliest occurrence of an O3 pollution episode was in April 2017. The 90th percentile and average concentrations of O3 in the industrial zone increased at faster rates (average annual growth of 16.0 µg·m-3 and 13.0 µg·m-3, respectively) than of those in the urban and suburban zones. The O3 concentrations at the suburban site showed the fastest increase of all zones at the 5th percentile (average annual growth of 13.2 µg·m-3). The monthly variation in O3 concentrations in Anyang showed an "M" pattern that varied spatially depending on the zone. Temperature played a leading role in O3 concentrations; air temperatures >23℃, relative humidity <58%, and a wind speed of 5 m·s-1 in a south-southwesterly direction were closely related to the occurrence of high O3 concentrations. Potential sources of O3 in different seasons were significantly different, and mainly distributed in southern Hebei, northern Hubei, and northern Shenyang in summer. The first heavy O3 pollution day in the studied period was in May 2017, at which time the highest O3 concentration was found in the industrial zone (up to 405 µg·m-3). This heavy O3 pollution episode was related to the continuous high temperature that was caused by the transfer of a dry, hot air mass in western China.

ABSTRACT

Two novel heterometallic organic frameworks built from trinuclear indium and cuprous halide clusters, [(In3O)2(Cu2I2)3(ina)12(H2O)6](NO3)2·7DMA·10H2O (1) and [NH2(CH3)2][In3(OH)2(H2O)2(ina)8(Cu4I4)2]·5DMA·8H2O (2), where Hina = isonicotinic acid, have been successfully constructed with the orientation of the ina ligand. 1 shows a fascinating highly porous honeycomb-like 3D cationic framework with a trigonal-bipyramid-type cage based on a planar [In3O(CO2)6]+ trimer and a rhombohedral Cu2I2 cluster. Comparably, 2 displays a 3D negative network with irregular hexagonal channels constructed from a [In3(OH)2(CO2)8]- trimer and a cubane-like Cu4I4 cluster. Especially, 1 displays a reversible I2 adsorption/release performance with high adsorption capacity, whose mechanism has been disclosed by theoretical simulation. Also, the green/red emission of 2 stems from iodocuprate centers with quenched indium-centered emission.

ABSTRACT

A protein-sized (ca. 4.2×4.2×3.6 nm3 ) non-biologically derived molecule {Nb288 O768 (OH)48 (CO3 )12 } (Nb288 ) containing up to 288 niobium atoms has been obtained, which is by far the largest and the highest nuclearity polyoxoniobate (PONb). Particularly, in terms of metal nuclearity number, Nb288 is the second largest cluster so far reported in classic polyoxometalate chemistry (V, Mo, W, Nb, and Ta). Nb288 can be described as a giant windmill-like cluster aggregate of six nanoscale high-nuclearity PONb units {Nb47 O128 (OH)6 (CO3 )2 } (Nb47 ) joined together by six additional Nb ions. Interestingly, the 47-nuclearity Nb47 units generated in situ can be isolated and bridged by copper complexes to form an inorganic-organic hybrid three-dimensional PONb framework, which exhibits effective catalytic activity for hydrolyzing nerve agent simulant of dimethyl methylphosphonate. The unique Nb47 cluster also provides a new type of topology to very limited family of Nb-O clusters.

ABSTRACT

A series containing the highest nuclearity polyoxoniobate (PONb) nanoclusters, ranging from dimers to tetramers, has been obtained. They include one 114-nuclear {Li8 ⊂Nb114 O316 }, one 81-nuclear {Li3 K⊂Nb81 O225 }, and one 52-nuclear {H4 Nb52 O150 }. The Nb nuclearity of these PONbs is remarkably larger than those of all known high-nuclearity PONbs (≤32). Furthermore, the introduction of 3d Cu2+ ions can lead to the generation of extended inorganic-organic hybrid frameworks built from novel, high-nuclearity, nanoscale heterometallic PONb building blocks {H3 Cu3 Nb78 O222 } or {H3 Cu4 (en)Nb78 O222 }. These building blocks also contain the largest number of Nb centers of any heterometallic PONbs reported to date. The synthesis of new-type PONbs has long been a challenging subject in PONb chemistry.

ABSTRACT

The two novel cluster organic frameworks based on heterometallic supertetrahedral cluster secondary building units (SBUs) [Cd4Cu6(L)4(Ac)7(H2O)4](Ac)·7H2O (1) and [Mn4Cu6(L)4(Ac)4.5(H2O)9]CuCN(Ac)3.5·H2O (2), where H3L = 2-(hydroxymethyl)-2-(pyridin-4-yl)-1,3-propanediol and Ac = CH3COO-, have been prepared under solvothermal conditions. 1 and 2 are the first cases of cluster organic frameworks containing Cd-Cu/Mn-Cu heterometallic supertetrahedral cluster SBUs. Furthermore, 1 and 2 show an integration of magnetic properties and adsorption properties from both the heterometallic cluster secondary building units and the framework in a porous material.

ABSTRACT

Two novel cluster-organic frameworks based on the 12-nuclearity manganese-cluster secondary building unit (SBU), [MnIII4MnII8(L)4(Ac)8(MeO)2(µ5-O)2(H2O)4](Ac)2·16H2O (1) and [MnIII4MnII8(L)4(Ac)8(MeO)2(µ5-O)2(H2O)4](Ac)2·12H2O (2), where Ac = CH3COO- and MeO = CH3O, have been constructed from solvothermal reactions of the 3-nuclearity manganese cluster [Mn3(µ3-O)(Ac)6(py)3](ClO4) (Mn3, where py = pyridine) with a tripodal alcohol ligand containing a 4-pyridyl group. 1 and 2 represent the first examples of metal-organic frameworks containing 12-nuclearity manganese-cluster SBUs. In addition, 1 exhibits an integration of the porosity and magnetic properties from both the framework and cluster in a porous material.

ABSTRACT

The first series of niobium-tungsten-lanthanide (Nb-W-Ln) heterometallic polyoxometalates {Ln12 W12 O36 (H2 O)24 (Nb6 O19 )12 } (Ln=Y, La, Sm, Eu, Yb) have been obtained, which are comprised of giant cluster-in-cluster-like ({Ln12 W12 }-in-{Nb72 }) structures built from 12 hexaniobate {Nb6 O19 } clusters gathered together by a rare 24-nuclearity sodalite-type heterometal-oxide cage {Ln12 W12 O36 (H2 O)24 }. The Nb-W-Ln clusters present the largest multi-metal polyoxoniobates and a series of rare high-nuclearity 4d-5d-4f multicomponent clusters. Furthermore, the giant Nb-W-Ln clusters may be isolated as discrete inorganic alkali salts and can be used as building blocks to form high-dimensional inorganic-organic hybrid frameworks.

ABSTRACT

A step-by-step synthetic strategy, setting up a bridge between the polyoxometalate (POM) and metal halide cluster (MHC) systems, is demonstrated to construct an unprecedented composite hybrid cluster built up from one high-nuclearity cationic MHC [Cu8I6](2+) and eight Anderson-type anionic POMs [HCrMo6O18(OH)6](2-) cross-linked by a tripodal alcohol derivative.

ABSTRACT

A series of sulforaphane derivatives were synthesized and evaluated in vitro for their cytotoxicity against five cancer cell lines (HepG2, A549, MCF-7, HCT-116 and SH-SY5Y). The pharmacological results showed that many of the derivatives displayed more potent cytotoxicity than sulforaphane (SFN). Furthermore, SFN and derivative 85 could induce cell cycle arrest at S or G2/M phase and cell apoptosis. SFN and 85 exhibited time- and dose-dependent activation on Nrf2 transcription factor, and 85 acted as a more potent Nrf2 inducer than SFN.

ABSTRACT

Pollution levels of perfluorochemicals in eggs purchased from the markets in Beijing had been investigated. The egg samples of chicken and duck were collected from the 59 stalls of 14 main eggs wholesale markets in Beijing, respectively. Systematic analyses were made for seventeen kinds of perfluorochemicals (11 perfluorinated carboxylates (PFCAs), 3 perfluorinated sulfonates (PFSAs), perfluorooctane sulfonamide (FOSA), 2-perfluorooctylethanoic acid (FOEA) and 2H-perfluoro-2-decenoic acid (FOUEA) by a high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The results showed that there was a certain perfluorochemical contamination in all egg samples. Nine kinds of perfluorochemicals were detected in chicken eggs, perfluorononanoic acid (PFNA), perfluoroheptanoic acid (PFHpA) and perfluorooctanoate acid (PFOA) are dominant, and their average concentrations were 0.105, 0.073 and 0.069 ng x g(-1), respectively. Ten kinds of perfluorochemicals were detected in the duck eggs, perfluorooctane sulfonate (PFOS) and PFOA are dominant, and their average concentrations were 0.378 and 0.296 ng x g(-1), respectively. Perfluoropentanoic acid ( PFPeA), perfluorotetradecanoic acid (PFTA), perfluorobutane sulfonate (PFBS) and 2-perfluorooctylethanoic acid (FOEA) were not detected in all samples. The total concentration of PFCs in the duck eggs was 3.4 times of that in the chicken eggs. A strong positive correlation (r = 0.954) was not only observed between of PFNA and PFHpA in chicken eggs, but also found between perfluoroundecanoic acid (PFUnDA) and perfluorotridecanoic acid (PFTrDA) in duck eggs (r = 0.915). The results of health-based risk assessment showed that there was little immediate risk of exposure to PFOS and PFOA via the consumption of chicken eggs and duck eggs purchased from the markets in Beijing.
