| 1 | Accumulation of carotenoids and expression of carotenoid biosynthesis genes in fruit flesh during fruit development in two Cucurbita maxima inbred lines显示文摘Mesocarp color is an important agronomic trait of Cucurbita maxima and is determined mainly by the contents and compositions of the carotenoids.The two inbred lines with significant differences in fruit flesh color were used in the study,the orange’312-1’and white’98-2’.Changes in seven carotenoid contents and compositions in the flesh of fruit produced by inbred lines’312-1’and’98-2’were analyzed during fruit development.The expression of eight key carotenoid biosynthesis genes in the fruit flesh were investigated during five fruit development stage in two inbred lines.As the flesh color intensified,the orange flesh color of’312-1’was determined mainly by the increased contents of lutein,β-carotene and zeaxanthin and the lack of carotenoid accumulation led to the formation of white flesh in’98-2’fruit.The expression of the LCY-e and CHYb genes was significantly stronger in’312-1’than in’98-2’,and their expression was strongly correlated with lutein andβ-carotene contents during fruit development.This study provides a deep understanding of the molecular mechanism of carotenoid biosynthesis in fruit flesh and provides a basis for additional studies on the highly refined improvement of squash quality. | Yusong Luo Chaojie Wang Manman Wang Yunli Wang Wenlong Xu Hongyu Han Zhichao Wang Yujuan Zhong Hexun Huang Shuping Qu | 2021 | Horticultural Plant Journal2021，7，6： | 3 |
| 2 | Genetic Architecture of Childhood Kidney and Urological Diseases in China显示文摘Kidney disease is manifested in a wide variety of phenotypes,many of which have an important hereditary component.To delineate the genotypic and phenotypic spectrum of pediatric nephropathy,a multicenter registration system is being imple-mented based on the Chinese Children Genetic Kidney Disease Database(CCGKDD).In this study,all the patients with kidney and urological diseases were recruited from 2014 to 2020.Genetic analysis was conducted using exome sequencing for families with multiple affected individuals with nephropathy or clinical suspicion of a genetic kidney disease owing to early-onset or extrarenal features.The genetic diagnosis was confirmed in 883 of 2256(39.1%)patients from 23 provinces in China.Phenotypic profiles showed that the primary diagnosis included steroid-resistant nephrotic syndrome(SRNS,23.5%),glomerulonephritis(GN,32.2%),congenital anomalies of the kidney and urinary tract(CAKUT,21.2%),cystic renal disease(3.9%),renal calcinosis/stone(3.6%),tubulopathy(9.7%),and chronic kidney disease of unknown etiology(CKDu,5.8%).The pathogenic variants of 105 monogenetic disorders were identified.Ten distinct genomic disorders were identified as pathogenic copy number variants(CNVs)in 11 patients.The diagnostic yield differed by subgroups,and was highest in those with cystic renal disease(66.3%),followed by tubulopathy(58.4%),GN(57.7%),CKDu(43.5%),SRNS(29.2%),renal calcinosis/stone(29.3%)and CAKUT(8.6%).Reverse phenotyping permitted correct identification in 40 cases with clinical reassessment and unexpected genetic conditions.We present the results of the largest cohort of children with kidney disease in China where diagnostic exome sequencing was performed.Our data demonstrate the utility of family-based exome sequencing,and indicate that the combined analysis of genotype and phenotype based on the national patient registry is pivotal to the genetic diagnosis of kidney disease. | Ye Fang Hua Shi Tianchao Xiang Jiaojiao Liu Jialu Liu Xiaoshan Tang Xiaoyan Fang Jing Chen Yihui Zhai Qian Shen Guomin Li Li Sun Yunli Bi Xiang Wang Yanyan Qian Bingbing Wu Huijun Wang Wenhao Zhou Duan Ma Jianhua Mao Xiaoyun Jiang Shuzhen Sun Ying Shen Xiaorong Liu Aihua Zhang Xiaowen Wang Wenyan Huang Qiu Li Mo Wang Xiaojie Gao Yubin Wu Fang Deng Ruifeng Zhang Cuihua Liu Li Yu Jieqiu Zhuang Qing Sun Xiqiang Dang Haitao Bai Ying Zhu Siguang Lu Bili Zhang Xiaoshan Shao Xuemei Liu Mei Han Lijun Zhao Yuling Liu Jian Gao Ying Bao Dongfeng Zhang Qingshan Ma Liping Zhao Zhengkun Xia Biao Lu Yulong Wang Mengzhun Zhao Jianjiang Zhang Shan Jian Guohua He Huifeng Zhang Bo Zhao Xiaohua LI Feiyan Wang Yufeng Li Hongtao Zhu Xinhui Luo Jinghai Li Jia Rao Hong Xu | 2021 | Phenomics2021，1，3： | 0 |
| 3 | Determination of atractylon in rat plasma by a GC-MS method and its application to a pharmacokinetic study显示文摘A sensitive and selective method based on gas chromatography hyphenated to mass spectrometry(GCMS) was developed and validated for the determination of atractylon in rat plasma.Plasma samples were processed by liquid-liquid extraction with ethyl acetate-n-hexane(1:1,v/v) using acetophenone as an internal standard(IS).Analytes were determined in selective ion monitoring(SIM) mode using target ions at m/z 108.1 for atractylon and m/z 105.1 for acetophenone.The calibration curve was linear over the concentration range of 10-1000 ng/mL with lower limit of quantification of 10 ng/mL The intra- and inter-day precision variations were not more than 10.4%and 9.6%,respectively,whilst accuracy values ranged from-6.5%to 4.9%.Extraction recovery of the assay was satisfactory.This method was successfully applied to quantification and pharmacokinetic study of atractylon in rat plasma after intragastric administration of Atractylodis extract. | Han Yan Yuanyuan Sun Yuying Ma Bin Ji Xiaohong Hou Zhiguo Yu Yunli Zhao | 2015 | Journal of Pharmaceutical Analysis2015，5，5： | 0 |
| 4 | Untargeted and targeted mass spectrometry reveal the effects of theanine on the central and peripheral metabolomics of chronic unpredictable mild stress-induced depression in juvenile rats显示文摘L-theanine has been shown to have a therapeutic effect on depression.However,whether L-theanine has an excellent preventive effect on depression in children and adolescents and what its mechanism is have not been well explained.Given the complexity of the pathogenesis of depression,this study investigated the preventive effect and mechanism of L-theanine on depression in juvenile rats by combining serum and hippocampal metabolomic strategies.Behavioral tests,hippocampal tissue sections,and serum and hippocampal biochemical indexes were studied,and the results confirmed the preventive effect of Ltheanine.Untargeted reversed-phase liquid chromatography-quadrupole-time-of-flight mass spectrometry and targeted hydrophilic interaction liquid chromatography-triple quadrupole mass spectrometry were developed to analyze the metabolism changes in the serum and hippocampus to screen for potential biomarkers related to L-theanine treatment.The results suggested that 28 abnormal metabolites in the serum and hippocampus that were considered as potential biomarkers returned to nearnormal levels after L-theanine administration.These biomarkers were involved in various metabolic pathways,mainly including amino acid metabolism and lipid metabolism.The levels of amino acids and neurotransmitters in the phenylalanine,tryptophan,and glutamic acid pathways were significantly reduced after L-theanine administration compared with chronic unpredictable mild stress-induced rats.In summary,L-theanine had a significant preventive effect on depression and achieved its preventive results on depression by regulating various aspects of the body,such as amino acids,lipids,and inflammation.This research systematically analyzed the mechanism of L-theanine in preventing depression and laid the foundation for applying L-theanine to prevent depression in children and adolescents. | Yanru Zhu Feng Wang Jiatong Han Yunli Zhao Miao Yu Mingyan Ma Zhiguo Yu | 2023 | Journal of Pharmaceutical Analysis2023，13，1： | 0 |
| 5 | Intravenous immunoglobulin accompanied with high-dose methylprednisolone therapy for 17 children with anti-N-methyl-D-aspartate receptor encephalitis:Clinic and nursing显示文摘Objective:An increasing number of pediatric patients are being diagnosed with anti-N-methyl-Daspartate receptor(NMDAR)encephalitis,whose treatment requires immunotherapy through nursing interventions.This study aimed to analyze the clinical features and long-term prognosis of pediatric anti-NMDAR encephalitis and to gather nursing experiences of immunotherapy.Methods:Seventeen children diagnosed with anti-NMDAR encephalitis were admitted to the pediatric department.They were subjected to a therapy of intravenous immunoglobulin(IVIG)accompanied with high-dose methylprednisolone(HDMP).Multidisciplinary cooperation and intensive care were used to manage them.The effects of nursing intervention and therapy were repeatedly assessed and analyzed throughout the course of treatment and recovery.Results:None of the patients manifested adverse drug reaction(ADR)during IVIG administration.At the first administration of HDMP,ADRs were promptly and efficiently treated in four patients(24%;i.e.,one case each of hyperglycosemia,hypertension,aggravated symptoms,and gastrointestinal bleed).Two patients underwent rehabilitation,and six patients received hyperbaric oxygenation during hospitalization.Nine patients with indwelling gastric tubes experienced four times of unplanned extubation.Hospital stay ranged from 11 days to 59 days,with the mean duration of 26 days.Discharge evaluation revealed that 16 patients who scored 0e2 on the modified Rankin scale presented obvious remission,and one patient who had a mRS score of 4 exhibited less improvement.The mRS scores of hospitalization,discharge,and six-month follow-up displayed statistically significant differences.Conclusions:Nursing interventions of immunotherapy ensures the security of IVIG administration.Multidisciplinary cooperation promotes remission.Our findings can serve as reference for healthcare teams. | Huihan Zhao Yunli Han Yu He Huiqiao Huang Qin Wei Pengpeng Wang Yanping Ying | 2016 | International Journal of Nursing Sciences2016，3，4： | 0 |
