ABSTRACT

Abstract Ri chicken is the most popular backyard chicken breed in Vietnam, but little is known about the growth curve of this breed. This study compared the performances of models with three parameters (Gompertz, Brody, and Logistic) and models containing four parameters (Richards, Bridges, and Janoschek) for describing the growth of Ri chicken. The bodyweight of Ri chicken was recorded weekly from week 1 to week 19. Growth models were fitted using minpack.lm package in R software and Akaike's information criterion (AIC), Bayesian information criterion (BIC), and root mean square error (RMSE) were used for model comparison. Based on these criteria, the models having four parameters showed better performance than the ones with three parameters, and the Richards model was the best one for males and females. The lowest and highest value of asymmetric weights (α) were obtained by Bridges and Brody models for each of sexes, respectively. Age and weight estimated by the Richard model were 8.46 and 7.51 weeks and 696.88 and 487.58 g for males and for females, respectively. Differences in the growth curves were observed between males and female chicken. Overall, the results suggested using the Richards model for describing the growth curve of Ri chickens. Further studies on the genetics and genomics of the obtained growth parameters are required before using them for the genetic improvement of Ri chickens.


Resumo O frango Ri é a raça de frango de quintal mais popular do Vietnã, mas pouco se sabe sobre a curva de crescimento dessa raça. Este estudo comparou o desempenho de modelos com três parâmetros (Gompertz, Brody e Logistic) e modelos contendo quatro parâmetros (Richards, Bridges e Janoschek) para descrever o crescimento do frango Ri. O peso corporal do frango Ri foi registrado semanalmente da semana 1 à semana 19. Os modelos de crescimento foram ajustados usando o pacote minpack.lm no software R e o critério de informação de Akaike (AIC); critério de informação bayesiano (BIC) e erro quadrático médio (RMSE) foram usados ​​para comparação de modelos. Com base nesses critérios, os modelos com quatro parâmetros apresentaram melhor desempenho do que os com três parâmetros, sendo o modelo de Richards o melhor para homens e mulheres. O menor e o maior valor dos pesos assimétricos (α) foram obtidos pelos modelos Bridges e Brody para cada um dos sexos, respectivamente. A idade e o peso estimados pelo modelo de Richard foram de 8,46 e 7,51 semanas e 696,88 e 487,58 g para homens e mulheres, respectivamente. Diferenças nas curvas de crescimento foram observadas entre frangos machos e fêmeas. No geral, os resultados sugeriram o uso do modelo de Richards para descrever a curva de crescimento de frangos Ri. Mais estudos sobre a genética e genômica dos parâmetros de crescimento obtidos são necessários antes de usá-los para o melhoramento genético de frangos Ri.

ABSTRACT

RESUMO: Introdução: apesar de ser o país de maior média de idade no mundo, o Japão tem se destacado no combate à pandemia da COVID-19 (do inglês Coronavirus Disease 2019) ao apresentar reduzidas taxas de contaminação pelo vírus e de mortalidade. Objetivo: discutir acerca das estratégias em saúde adotadas pelo Japão diante da pandemia da doença da COVID-19, bem como avaliar os dados sobre contaminação e mortalidade japoneses em comparação com os outros quatro países com maior média de idade do mundo (Itália, Alemanha, Portugal e Espanha) e o Brasil. Metodologia: para avaliação das estratégias em saúde japonesas foi realizada busca nas bases de dados: PubMed, Cochrane e Scielo, utilizando-se combinação dos termos "Japão", "covid", "coronavirus" e "sistemas de saúde", nos idiomas Inglês, Espanhol e Português. Os dados de infecção da COVID-19 foram extraídos do site Our World in Data, correspondendo ao período de 25 de janeiro de 2020 a 30 de julho de 2020. Resultados: dentre as medidas adotadas pelo país no enfrentamento à pandemia, destacam-se o diagnóstico e resposta precoces à infecção, o rastreamento de contatos, o diagnóstico precoce e disponibilidade de cuidados intensivos para pacientes graves e estímulo a medidas comportamentais de distanciamento. Dentre os países analisados, o Japão apresenta as menores taxas de contaminação e mortalidade em termos absolutos pela COVID-19. Conclusões: medidas de distanciamento social, diagnóstico e tratamento precoces parecem ter contribuído para o sucesso no combate à COVID-19 no Japão. No período estudado, em milhão de habitantes, o Japão teve 6,13 casos de Covid, enquanto o Brasil apresentou 218,26 casos. Já no número de mortes confirmadas pela doença, o primeiro teve uma taxa de 0,23 enquanto o segundo de 5,16 casos por milhão de habitantes. É possível, a partir do conhecimento dessas medidas, buscar mecanismos semelhantes ao traçar políticas de saúde no enfrentamento de pandemias em outros países. (AU)


ABSTRAC: Introduction: despite being the country with the highest average age globally, Japan has stood out in the fight against the COVID-19 (Coronavirus Disease 2019) pandemic by presenting low contamination rates by the virus and mortality. Objective: we aim to discuss the health strategies adopted by Japan in the face of the COVID-19 disease pandemic, as well as to evaluate data on Japanese contamination and mortality compared to the other four countries with the highest average age in the world (Italy, Germany, Portugal and Spain) and Brazil. Methodology: the search was carried out to evaluate Japanese health strategies by using the following databases: PubMed, Cochrane, and Scielo using a combination of the terms "Japan", "covid", "coronavirus" and "health systems" in English, Spanish and Portuguese. The COVID-19 infection data was extracted from the Our World in Data website, from January 25, 2020, to July 30, 2020. Results: Among the measures adopted by the country to face the pandemic, the early diagnosis and response to infection, contact tracing, early diagnosis and availability of intensive care for critically ill patients, and encouraging behavioral distancing measures stand out. Among the countries analyzed, Japan has the lowest rates of contamination and mortality in absolute terms by COVID-19. Conclusions: social distancing measures, early diagnosis, and treatment seem to have contributed to the success in combating COVID-19 in Japan. In the studied period, in a million inhabitants, Japan had 6.13 cases of covid while Brazil had 218.26 cases. As for the number of deaths confirmed by the disease, the first had a rate of 0.23 while the second had 5.16 cases per million inhabitants. Based on the knowledge of these measures, it is possible to seek similar mechanisms when designing health policies to face pandemics in other countries.(AU)

ABSTRACT

Chinese Society of Colorectal Surgery firstly issued guidelines on the chronic constipation in 2008, which played a positive role in the standardization of chronic constipation surgery in China. In recent years, some progress has been made in the basic and clinical researches on chronic constipation. But in terms of clinical practice, there is still a lack of gold standard and high-level clinical research evidence, and surgeons have no authoritative reference in preoperative evaluation, operation selection and efficacy evaluation. In order to further standardize the diagnostic assessment and surgical treatment of chronic constipation, it is necessary to update the guidelines. Based on the published literatures combined with the clinical experience of experts, the "Clinical practice guideline on the evaluation and management of chronic constipation for Chinese adults (2022 edition)" has been formulated, which aims at the common problems in constipation assessment and treatment, is problem-oriented, and puts forward rationalization suggestions on the basis of evidence. It is expected to contribute to the learning and practice on constipation for Chinese surgeons and other relevant medical practitioners, and improve the overall diagnosis and treatment level of constipation surgery in China.

ABSTRACT

OBJECTIVES@#To study the clinical value of attention time combined with behavior scale in the screening of attention deficit hyperactivity disorder (ADHD) in preschool children.@*METHODS@#A total of 200 preschool children with ADHD diagnosed in Fujian Maternal and Child Health Hospital from February 2019 to March 2020 were enrolled as the ADHD group. A total of 200 children who underwent physical examination in the hospital or kindergartens during the same period were enrolled as the control group. Attention time was recorded. Chinese Version of Swanson Nolan and Pelham, Version IV Scale-Parent Form (SNAP-IV) scale was used to evaluate symptoms. With clinical diagnosis as the gold standard, the decision tree analysis was used to evaluate the clinical value of attention time combined with behavior scale in the screening of ADHD.@*RESULTS@#Compared with the control group, the ADHD group had significantly higher scores of SNAP-IV items 1, 4, 7, 8, 10, 11, 14, 15, 16, 18, 20, 21, and 22 (P<0.05) and a significantly shorter attention time (P<0.05). The variables with statistically significant differences between the two groups in univariate analysis were used as independent variables to establish a decision tree model. The accuracy of the model in predicting ADHD was 81%, that in predicting non-ADHD was 69%, and the overall accuracy was 75%, with an area under the ROC curve of 0.816 (95% CI: 0.774-0.857, P<0.001).@*CONCLUSIONS@#The decision tree model for screening ADHD in preschool children based on attention time and assessment results of behavior scale has a high accuracy and can be used for rapid screening of ADHD among children in clinical practice.

ABSTRACT

OBJECTIVE@#To explore the genotype-phenotype correlation of a case with GM1-gangliosidosis caused by compound heterogenic variants in GLB1.@*METHODS@#Genomic DNA was extracted from peripheral blood samples from the patient and her parents. Trio-based whole-exome sequencing (WES) was performed for the family and suspected mutation was verified by Sanger sequencing.@*RESULTS@#The proband, a 2-year-3-month old Chinese girl, presented with psychomotor deterioration, absent speech, intellectual disabilities and behavior problem. Trio-based WES has identified compound heterozygosity for 2 variants in the GLB1 gene: NM_000404.2:c.1343A>T, p.Asp448Val and c.1064A>C, p.Gln355Pro (GRCh37/hg19),which was inherited from the mother and father, respectively. Homozygous or compound heterozygous pathogenic variants in GLB1, encoding β-galactosidase, are responsible for GM1-gangliosidosis,an autosomal recessive lysosomal storage disorder characterized by variable degrees of neurodegeneration and skeletal abnormalities. The p.Asp448Val variant has been classified as pathogenic for GM1 gangliosidosis in medical literatures for the reason that functional studies demonstrated that expression of the p.Asp448Val variant in COS-1 cells resulted in no detectable β-galactosidase activity compared to wild type GLB1. The p.Gln355Pro variant has not been reported in literatures or database. The variant is highly conserved residue (PM1), and was not found in either the Genome Aggregation Database or the 1000 Genomes Project (PM2) and was predicted to have a deleterious effect on the gene product by multiple in silico prediction tools (PP3). Next, the β-galactosidase activity of the patient's peripheral blood leukocytes was determined by fluorescent method. The result was 0.0 nmol/mg. It showed that the p.Gln355Pro variant also resulted in loss of β-galactosidase activity, thus the variant was classified into clinical pathogenic variant.@*CONCLUSION@#Our study expands the mutational spectrum of the GLB1 gene and provides genetic counseling for the family.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a child featuring complex cortical dysplasia and other brain malformations (CDCBM3).@*METHODS@#Genomic DNA was extracted from peripheral blood samples from the patient and his parents. Whole exome sequencing (WES) was carried out for the family trio. Suspected variant was verified by Sanger sequencing.@*RESULTS@#The proband, a 1-year-and-2-month old Chinese boy, had presented with motor developmental delay, lissencephaly, severe cognitive impairments, absent speech and congenital laryngomalacia. WES revealed that he has harbored a heterozygous missense variant of the KIF2A gene, namely NM_001098511.2: c.952G>A, p.Gly318Arg (GRCh37/hg19). The highly conserved residue is located around the ATP nucleotide-binding pocket in the kinesin motor domain (PM1). The variant was not found in the Genome Aggregation Database and the 1000 Genomes Project (PM2), and was predicted to be deleterious on the gene product by multiple in silico prediction tools (PP3). This variant was unreported previously and was de novo in origin (PS2). Based on the ACMG guidelines, it was categorized as likely pathogenic (PS2+PM1+PM2+PP3). Furthermore, the congenital laryngomalacia found in our patient was absent in previously reported CDCBM3 cases.@*CONCLUSION@#The novel variant of the KIF2A gene probably underlay the disorders in the proband. Above finding has expanded the phenotypic and mutational spectrum of CDCBM3.

ABSTRACT

OBJECTIVE@#To determine the carrier rate for 21 inherited metabolic diseases among a Chinese population of childbearing age.@*METHODS@#A total of 897 unrelated healthy individuals (including 143 couples) were recruited, and DNA was extracted from their peripheral blood samples. Whole exome sequencing (WES) was carried out to screen potential variants among 54 genes associated with 21 inherited metabolic diseases. Pathogenic and likely pathogenic variants and unreported loss-of-function variants were analyzed.@*RESULTS@#One hundred fourty types of pathogenic/likely pathogenic variants (with an overall number of 183) and unreported loss-of-function variants were detected, which yield a frequency of 0.20 per capita. A husband and wife were both found to carry pathogenic variants of the SLC25A13 gene and have given birth to a healthy baby with the aid of preimplantation genetic diagnosis. The detected variants have involved 40 genes, with the most common ones including ATP7B, SLC25A13, PAH, CBS and MMACHC. Based on the Hardy-Weinberg equilibrium, the incidence of the 21 inherited metabolic diseases in the population was approximately 1/1100, with the five diseases with higher incidence including citrullinemia, methylmalonic acidemia, Wilson disease, glycogen storage disease, and phenylketonuria.@*CONCLUSION@#This study has preliminarily determined the carrier rate and incidence of 21 inherited metabolic diseases among a Chinese population of childbearing age, which has provided valuable information for the design of neonatal screening program for inherited metabolic diseases. Pre-conception carrier screening can provide an important measure for the prevention of transmission of Mendelian disorders in the population.

ABSTRACT

OBJECTIVE@#To analyze the clinical phenotype and genetic variant in a Chinese pedigree affected with benign familial neonatal convulsion (BFNC).@*METHODS@#Clinical data and peripheral blood samples of the pedigree were obtained with informed consent. Whole exome sequencing (WES) was carried out for the proband. Candidate variants were verified by Sanger sequencing.@*RESULTS@#The pedigree comprised 9 individuals, among whom 4 were affected, including 3 males and 1 female. All patients had developed seizures during the neonatal period, which had ceased in 4 to 6 months. One patient had recurrence in between 1 and 2 years old. Genetic testing has identified a novel nonsense c.810G>A (p.W270X) variant in exon 5 of the KCNQ2 gene, which has co-separated with the BFNC phenotype in the pedigree.@*CONCLUSION@#The patients from this pedigree have conformed to the diagnosis of BFNC with good prognosis, which was in keeping with previously reported cases. The heterozygous c.810G>A (p.W270X) nonsense variant of the KCNQ2 gene probably underlay the pathogenesis of BFNC in this pedigree, which has expanded the mutational spectrum of the disease.

ABSTRACT

OBJECTIVE@#To analyze the clinical features and variants of ABCD1 gene in a Chinese pedigree affected with X-linked adrenoleukodystrophy.@*METHODS@#Clinical data of the proband were collected and analyzed. Potential variant of the ABCD1 gene were analyzed by PCR and Sanger sequencing of the proband, his parents and 100 unrelated healthy individuals.@*RESULTS@#The prominent features of the proband included cerebellar and brainstem lesions, along with increased serum level of very-long chain fatty acids. He was found to harbor a hemizygous c.1509delG (p.L504Sfs*54) variant of the ABCD1 gene, for which his mother was heterozygous. The same variant was not detected in his father and 100 healthy controls.@*CONCLUSION@#X-linked adrenoleukodystrophy has a variety of clinical manifestations. Discovery of the c.1509delG (p.L504Sfs*54), as a novel pathogenic variant of the ABCD1 gene, has enabled diagnosis and genetic counseling for this pedigree.

ABSTRACT

Chinese medicine extracts are the important pharmaceutical materials of Chinese medicinal preparations, but their nomenclature still needs improvement in the field of traditional Chinese medicine(TCM). By the analysis of the evolution rules of names of Chinese medicine extracts recorded in the Chinese Pharmacopoeia, this study proposed a three-level nomenclature of "Chinese medicine name+chemical information+extract" based on the standardization problems involved in the existing nomenclature, striving to accurately suggest the material basic information on extract names. Meanwhile, the basic elements of Chinese medicine components, the special case from Chinese medicine extracts, were clarified, and the core connotations of the professional names were discriminated to arouse attention and discussions of researchers, facilitate the standardization of Chinese medicine terminology, and promote the scienti-fic development of Chinese medicinal preparations, and the modernization and internationalization of Chinese medicine.

ABSTRACT

Objective@#This study aimed to examine the sleep arrangements and soothing methods and to assess their associations with sleep problems among children aged < 3 years in China.@*Methods@#A cross-sectional survey was conducted in 2019 from six provinces in China. A total of 1,195 caregivers of children aged 0-35 months were included in the study. Data on sleep arrangements, soothing methods, and sleep problems (i.e., frequent night awakenings and difficulty falling asleep) were assessed using the Brief Infant Sleep Questionnaire. The reasons for bed-sharing in sleep arrangements were recorded using a self-designed questionnaire.@*Results@#The bed-sharing practice was very prevalent at any age, which ranged from 69.9% to 78.3%. Most infants fell asleep while feeding or being rocked/held before age 12 months. By age 35 months, 62.4% of the children fell asleep in bed near parents. The most common reasons for bed-sharing were breastfeeding/feeding and convenience. Parental involvement when falling asleep was significantly related with frequent night awakenings and difficulty falling asleep. No association was found between bed-sharing and sleep.@*Conclusion@#Bed-sharing and parental involvement were very common among Chinese children aged < 3 years. Children who fall asleep with parental involvement were more likely to have sleep problems.

ABSTRACT

Objective@#To explore associations between lipoprotein-associated phospholipase A2 (Lp-PLA2) and the risk of cardiovascular events in a Chinese population, with a long-term follow-up.@*Methods@#A random sample of 2,031 participants (73.6% males, mean age = 60.4 years) was derived from the Asymptomatic Polyvascular Abnormalities Community study (APAC) from 2010 to 2011. Serum Lp-PLA2 levels were determined by enzyme-linked immunosorbent assay (ELISA). The composite endpoint was a combination of first-ever stroke, myocardial infarction (MI) or all-cause death. Lp-PLA2 associations with outcomes were assessed using Cox models.@*Results@#The median Lp-PLA2 level was 141.0 ng/mL. Over a median follow-up of 9.1 years, we identified 389 events (19.2%), including 137 stroke incidents, 43 MIs, and 244 all-cause deaths. Using multivariate Cox regression, when compared with the lowest Lp-PLA2 quartile, the hazard ratios with 95% confidence intervals for developing composite endpoints, stroke, major adverse cardiovascular events, and all-cause death were 1.77 (1.24-2.54), 1.92 (1.03-3.60), 1.69 (1.003-2.84), and 1.94 (1.18-3.18) in the highest quartile, respectively. Composite endpoints in 145 (28.6%) patients occurred in the highest quartile where Lp-PLA2 (159.0 ng/mL) was much lower than the American Association of Clinical Endocrinologists recommended cut-off point, 200 ng/mL.@*Conclusion@#Higher Lp-PLA2 levels were associated with an increased risk of cardiovascular event/death in a middle-aged Chinese population. The Lp-PLA2 cut-off point may be lower in the Chinese population when predicting cardiovascular events.

ABSTRACT

OBJECTIVE@#To explore the association of single nucleotide polymorphisms (SNPs) of the vitamin D receptor gene ( VDR) with circulating lipids considering gender differences.@*METHODS@#Of the Han Chinese adults recruited from a health examination center for inclusion in the study, the circulating lipids, 25-hydroxyvitamin D (25OHD), and other parameters were measured. The VDR SNPs of Cdx2 (rs11568820), Fok1 (rs2228570), Apa1 (rs7975232), and Taq1 (rs731236) were genotyped with a qPCR test using blood DNA samples, and their associations with lipids were analyzed using logistic regression.@*RESULTS@#In the female participants ( n = 236 with dyslipidemia and 888 without dyslipidemia), multiple genotype models of Fok1 indicated a positive correlation of B (not A) alleles with LDLC level ( P < 0.05). In the male participants ( n = 299 with dyslipidemia and 564 without dyslipidemia), the recessive model of Cdx2 and the additive and recessive models of Fok1 differed ( P < 0.05) between the HDLC-classified subgroups, respectively, and Fok1 BB and Cdx2 TT presented interactions with 25OHD in the negative associations with HDLC ( P < 0.05).@*CONCLUSION@#In the Chinese Han adults included in the study, the Fok1 B-allele of VDR was associated with higher LDLC in females, and the Fok1 B-allele and the Cdx2 T-allele of VDR were associated with lower HDLC in males. The interaction of VD and Fok1 BB or Cdx2 TT in males synergistically decreased HDLC levels.

Organ transplantation is the most effective treatment for end stage organ failure,and voluntary donation after citizen's death is the only source of transplanted organ in China.Clinically,transplantation organ protection technology plays a critical role in improving the quality of transplantation organs and the prognosis of recipients.On the basis of domestic and worldwide basic research and clinical practice and according to the Oxford evidence classification and GRADE system,the experts organized by Organ Transplantation Doctor Branch of Chinese Medical Doctor Association,Organ Transplantation Group in Surgery Branch of Chinese Medical Association and China Liver Transplant Registry Scientific Committee had compiled and published the Chinese Expert Consensus on Organ Protection of Transplantation(2016 edition) for liver,kidney,pancreas,small intestine,heart,lung transplantation organs.With the support of China Liver Transplant Registry,National Center for Healthcare Quality Management in Liver Transplant,National Quality Control Center for Donated Organ Procurement,National Clinical Research Center for Orthopedics & Sports Medicine & Rehabilitation and National Trauma Medical Organ Protection Committee and combined with recent domestic and worldwide clinical practice and research progress for organ transplantation and organ protection,the Chinese Expert Consensus on Organ Protection of Transplantation(2022 edition)(hereinafter referred to as the consensus) has been formulated in 2022.This edition of the consensus focuses on updating the technical progress and evidence-based medicine of organ procurement,organ preservation,organ transport,and quality evaluation in clinical practice.Additionally,protection of composite tissue for transplantation,mainly including limb graft,has also been included.The organ protection strategy recommended in this consensus aims to promote scientific and standardize clinical organ transplantation work.

ABSTRACT

BACKGROUND@#Few studies have assessed the relationship between multimorbidity patterns and mortality risk in the Chinese population. We aimed to identify multimorbidity patterns and examined the associations of multimorbidity patterns and the number of chronic diseases with the risk of mortality among Chinese middle-aged and older adults.@*METHODS@#We used data from the China Kadoorie Biobank and included 512,723 participants aged 30 to 79 years. Multimorbidity was defined as the presence of two or more of the 15 chronic diseases collected by self-report or physical examination at baseline. Multimorbidity patterns were identified using hierarchical cluster analysis. Cox regression was used to estimate the associations of multimorbidity patterns and the number of chronic diseases with all-cause and cause-specific mortality.@*RESULTS@#Overall, 15.8% of participants had multimorbidity. The prevalence of multimorbidity increased with age and was higher in urban than rural participants. Four multimorbidity patterns were identified, including cardiometabolic multimorbidity (diabetes, coronary heart disease, stroke, and hypertension), respiratory multimorbidity (tuberculosis, asthma, and chronic obstructive pulmonary disease), gastrointestinal and hepatorenal multimorbidity (gallstone disease, chronic kidney disease, cirrhosis, peptic ulcer, and cancer), and mental and arthritis multimorbidity (neurasthenia, psychiatric disorder, and rheumatoid arthritis). During a median of 10.8 years of follow-up, 49,371 deaths occurred. Compared with participants without multimorbidity, cardiometabolic multimorbidity (hazard ratios [HR] = 2.20, 95% confidence intervals [CI]: 2.14 - 2.26) and respiratory multimorbidity (HR = 2.13, 95% CI:1.97 - 2.31) demonstrated relatively higher risks of mortality, followed by gastrointestinal and hepatorenal multimorbidity (HR = 1.33, 95% CI:1.22 - 1.46). The mortality risk increased by 36% (HR = 1.36, 95% CI: 1.35 - 1.37) with every additional disease.@*CONCLUSION@#Cardiometabolic multimorbidity and respiratory multimorbidity posed the highest threat on mortality risk and deserved particular attention in Chinese adults.
