ABSTRACT
ObjectiveTo visualize the research trends of verbal and nonverbal cognitive functions in patients with post-stroke aphasia (PSA). MethodsPapers about verbal and nonverbal cognitive functions after stroke were extracted from Web of Science Core Collection from establishment to August, 2022, and a bibliometric analysis was conducted on the distribution of articles published by year, author, journal, institution, and country. Author cooperation, author co-citation, journal co-citation, country/institution cooperation, dynamic evolution, keyword hotspots, and trends were visually analyzed by using VOSviewer software. ResultsA total of 1 630 publications were identified for final analysis. The first article related to the topic was retrieved in 2004. After that, the number of published papers showed an increasing trend year by year, with some fluctuations after 2019. Matthew A. Lambon Ralph and Elizabeth Jefferies were the authors who produced the most, were cited the most, and were the most influential. Neuropsychologia was a highly productive and well-cited publication. The University of Manchester in the United Kingdom and Johns Hopkins University in the United States were the nations/institutions with high yield and high centrality. Although China had a high yield and was in the top five, the centrality was insufficient. The dynamic emergence of keywords revealed that the research had gone through the following stages: evaluating the mechanism of language and nonverbal cognitive function impairment based on neuroimage, exploring the role of nonverbal cognitive dysfunction in pathology and recovery mechanisms of patients with PSA, examining the therapeutic mechanism of non-invasive brain stimulation and electronic tele-rehabilitation equipment, and revealing not only the frontal and temporal areas but also brain network supporting nonverbal cognition. ConclusionIn recent years, some achievements have been made in the researches on verbal and nonverbal cognitive function, particularly in the studies of the neuroimaging-based mechanisms of common damage and the intervention effects of synergistic therapy. In the future, academic cooperation between different regions and different teams needs to be strengthened. Further exploration should be focused on refining the cognitive neuropsychology and exploring new technologies to improve the therapeutic effect of PSA.
ABSTRACT
Childhood obesity is a global public health problem, which can not only endangers children's health, but also might be an important cause of chronic diseases in adulthood. In recent years, with the in-depth development of precision medicine research, more and more research evidences have shown that there are interactions between environmental factors, such as early intrauterine environment, children's diet, physical activity and children's gene factor on the incidence of childhood obesity, which can result in or inhibit the incidence and development of childhood obesity. This paper summarizes the progress in research in this field to reveal the effects and potential mechanisms of genetic factors and environmental factors on the incidence of childhood obesity in order to provide reference for the precise prevention and control of childhood obesity under different genetic backgrounds.

Objective: The fingerprint of Bupleurum chinense roots was developed with ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry(UPLC/Q-TOF-MS),the main chromatographic peaks were preliminary identified,and combined with principal component analysis(PCA) pattern recognition method to evaluate the quality of this herb from different origins. Method: The chromatographic separation was performed on a ZORBAX Eclipse Plus C18 column(2.1 mm×100 mm,1.8 μm) with a gradient elution of acetonitrile-0.1%formic acid aqueous solution.The mass spectrometer equipped with electrospray ionization(ESI) was used as detector and operated under the negative ion mode.Taking mass spectrometry data processing software of PeakView 1.2 and metabolomics analysis software of MarkerView 1.2.1,the different origins of B. chinense roots were analyzed by PCA. Result: The fingerprint of B. chinense roots was established within 35 min by UPLC/Q-TOF-MS.The samples from different origins were apparently classified by PCA.Eight compounds with significant differences were screened out,and the structures of three of them were identified as 3″-O-acetyl saikosaponin A,3″-O-acetyl saikosaponin D,6″-O-acetyl saikosaponin D. Conclusion: UPLC/Q-TOF-MS can be used for the rapid identification of fingerprint of B. chinense roots from different origins.IBM SPSS Statistics 21.0 and PCA can comprehensively distinguish the differences of chemical components in B. chinense roots from different origins and can be used to evaluate the quality of this herb.
ABSTRACT
Objectives This research explored the characteristics of changes in the serum metabolic profile of preeclampsia pregnancy(PE) to establish the disease distinguish model and screen characteristic metabolic markers with potential diagnostic value for preeclampsia.Methods From August 2014 to January 2016,samples in three groups were collected at Tianjin Third Central Hospital.Thirty-one clinically diagnosis patients with preeclampsia,25 normal pregnancy women and 29 healthy volunteers of childbearing age were enrolled.Ultraperformance liquid chromatography-mass spectrometry (UPLC-MS) was used to analyze serum metabolites of PE group (31 patients with preeclampsia),P group (25 normal pregnancy women) and Normal group (29 healthy volunteers of childbearing age).Nonparametric test analyzes were used to analyze the data and find the specific metabolites.Results This research established the principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) disease distinguish model for PE group,P group and Normal group.To distinguish PE group,P group and Normal group,15 characteristic metabolites were identified.Eight kinds of glycerol phospholipid (including 7 kinds of hemolysis phosphatidyl choline and 1 kind of lysophospholipids acid) and 1 kind of sphingomyelin in PE group were higher than that of normal pregnancy group.The difference had statistically significant(Z of the metabolites were 2.32,3.34,3.21,2.60,2.22,3.40,3.58,5.84,2.70 respectively,all P<0.05).1,25-Dihydroxyvitamin D3-26,23-lactone and 24-Oxo-1alpha,23,25-trihydroxyvitamin D3 in PE group were higher than that of P group and Normal group,which had a statistics difference (Z of the metabolites were 2.01,3.89,3.26,2.34 respectively,all P<0.05).Conclusions Metabolomics distinguish model has a good ability to distinguish PE group,P group and Normal group.Serum characteristic metabolites can successfully reflect the status of fat,calcium and phosphorus metabolism of preeclampsia patients and provide high value for prediction,diagnosis and treatment.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the interaction effects of breastfeeding and passive smoking on asthma and asthma related symptoms among children.</p><p><b>METHODS</b>Using a cluster random sampling method, 2 elementary schools and 1 kindergarten were randomly selected from 7 cities of Liaoning province. The resulting 25 elementary schools and 50 kindergartens were included, and 31 049 children from the selected schools living up to 2 years were recruited in this survey. The information about the children's type of feeding up, living environment, passive smoking exposure, respiratory diseases and symptoms were collected. The interaction effects of breastfeeding and passive smoking on asthma and asthma related symptoms (persistent cough,persistent phlegm, current wheeze and allergic rhinitis) were evaluated with Glimmix procedure.</p><p><b>RESULTS</b>There were 31 049 children involved in this investigation. The age was (8.32 ± 2.75) years old. There were 23 987 (77.26%) children with breastfeeding and 11 820 (38.07%) children with passive smoking. The prevalence of asthma and allergic rhinitis were 6.22%(1491/23 987), 4.67%(1120/23 987) in children with breastfeeding, and were 7.70%(544/7062), 5.48%(387/7062) in children without breastfeeding,compared to the children without breastfeeding, the children with breastfeeding had lower risk of asthma(OR = 0.79, 95%CI:0.72-0.88) and allergic rhinitis(OR = 0.85, 95%CI:0.75-0.95); The prevalence of current wheeze was 7.89%(929/11 770) in children with father smoking, and was 5.37%(1036/19 279) in children without father smoking, compared to the children without father smoking, the children with father smoking increased the risk of current wheeze(OR = 1.51, 95%CI:1.38-1.65). The prevalence of persistent cough was 18.96%(51/269) in children with mother smoking, and was 9.51%(2926/30 780) in children without mother smoking,compared to the children without mother smoking, the children with mother smoking increased the risk of persistent cough(OR = 2.23, 95%CI:1.64-3.03). The prevalence of persistent phlegm was 5.69%(871/5316) in children with anyone smoking, and was 3.50%(550/15 733) in children without anyone smoking, compared to the children without anyone smoking, the children with anyone smoking increased the risk of persistent phlegm(OR = 1.67, 95%CI:1.49-1.86).Glimmix procedure analysis showed there was a significant interaction effects between breastfeeding and passive smoking. The estimated OR for father smoking among breastfeeding children were consistently lower than those among non-breastfeeding children for asthma. The estimated OR for mother smoking among breastfeeding children were consistently lower than those among non-breastfeeding children for allergic rhinitis. The estimated OR for anyone smoking among breastfeeding children were consistently lower than those among non-breastfeeding children for asthma and allergic rhinitis(all P values < 0.05).</p><p><b>CONCLUSION</b>Breastfeeding decreases the detrimental effects of passive smoking on asthma and asthma related symptoms in children.</p>

<p><b>OBJECTIVE</b>To study the effects of indoor air pollution and individual susceptible factors on prevalence of children's asthma and asthma-related symptoms in Shenyang city.</p><p><b>METHODS</b>On April, 2007, 8733 Han children who were under age of 12 and lived for more than 2 years in Shenyang city, were selected from five administrative areas (one primary school and two kindergartens for each area) through cluster random sampling method. Information on children's general condition, asthma and related symptoms (including stridor, stridor symptoms, persistent cough, persistent phlegm), indoor air pollution, and susceptibility history were obtained by a standard questionnaire from the American Thoracic Society. The effects of indoor air pollution on asthma and asthma-related symptoms was analyzed through χ(2) test. Logistic regression was used to research the effects of risk factors on the prevalence of asthma and asthma-related symptoms of both susceptible and non-susceptible children.</p><p><b>RESULTS</b>Among the 8733 subjects, 4420 (50.6%) were boy and 4313 (49.4%) were girl, with the age of (8.08 ± 2.88) years old. The prevalence of asthma, current asthma, cough, persistent phlegm, stridor and stridor symptom were 6.4% (559 cases), 2.5% (215 cases), 9.6% (836 cases), 4.4% (386 cases), 17.5% (1524 cases) and 2.6% (229 cases) respectively. The prevalence of asthma the boys and girls were among 7.1% (313 cases) and 5.7% (246 cases) (χ(2) = 6.916, P < 0.05); and stridor symptom for them were 19.2% (850 cases), 15.6% (674 cases) (χ(2) = 19.678, P < 0.05), respectively. Passive smoking before two years old, house decoration and pet were related to asthma of children, and there was significant difference between the two groups. The prevalence of asthma of exposed children were 7.7% (312 cases), 9.5% (159 cases), 8.0% (270 cases), 9.0% (114 cases), respectively. Compared with the non-exposed children who had asthma, the prevalence of asthma were 5.7% (400 cases), 5.4% (289 cases), 6.0% (445 cases), the value of χ(2) were 33.646, 23.944 and 16.527 respectively (all P values < 0.05). Children who had family history of asthma, family history of allergy and allergy history were also related with asthma, the prevalence of asthma were 17.3% (106 cases), 13.1% (85 cases), 22.0% (147 cases), compared with the non-exposed children who had asthma, the prevalence of asthma were 5.5% (453), 5.9% (474), 5.1% (412), and there was significant difference between the two groups, the value of χ(2) were 130.522, 59.929 and 293.997, respectively (all P values < 0.05). Logistic regression analysis showed that passive smoking (OR = 1.7, 95%CI: 1.2 - 2.4), house decoration (OR = 1.5, 95%CI: 1.1 - 1.9) and pet (OR = 1.6, 95%CI: 1.1 - 2.3) were statistically significant to asthma in non-susceptible children. While passive smoking (OR = 1.3, 95%CI: 1.0 - 1.7) and house decoration (OR = 1.4, 95%CI: 1.1 - 1.7) were increased the risk of asthma.</p><p><b>CONCLUSION</b>Indoor air pollution is a risk factor of children' s asthma. Family history of asthma and physical susceptible children are high risk to asthma, and susceptible children are easily influenced by other risk factors.</p>
