Objective: The study aims to explore malnutrition issues among infants under five years old in Guéra Province. Methods: The study used a cross-sectional design and a two-stage cluster sampling method to select participants. The study population was infants aged between 0 - 24 months. Data collection was done between June 2023 and September 2024;it included anthropometric measurements, blood analyses, and interviews. Anthropometric parameters were calculated using ENA for SMART software. Statistical analyses were performed by R Studio to investigate associations between different characteristics, using logistic regression models to identify risk factors. A p-value less than 0.05 was considered significant. Results: The study included 377 infants in eight villages in Guéra Province, Chad. The sample was predominantly girls (55.3%), with a median age of 16 months. Most infants (94%) were mixed-fed, and only 6% were exclusively breastfed. We found that 7.3% of children were globally malnourished, with higher rates in boys 9.6%. A significant disparity existed between boys and girls in global acute malnutrition (GAM) rates, with boys having a higher prevalence of 17.9%. A substantial proportion of Infants were underweight, with males 27.4%. Stunting was prevalent 20.1%. Several factors were associated with malnutrition, including gender, feeding practices, infectious diseases, and socioeconomic factors. Diarrhea, malaria, limited access to drinking water, and early diet diversification were significantly associated with malnutrition. Conclusion: Targeted interventions are necessary to address these issues and improve the nutritional status of children in the Guéra province.展开更多

WHO revised its earlier recommendation of Exclusive Breastfeeding (EBF) of infants from 4 to 6 months of age to EBF until about 6 months of age, with the addition of complementary foods thereafter. This recommendation confirms that breast milk alone is sufficient to meet infants’ nutritional requirements for the first 6 months of life. The main objective of this study was to investigate the effect of various feeding practices on the Nutritional status of infants 0 - 12-month-old in the Kumba 1 Sub-Division. A descriptive cross-sectional study was conducted from December 2019 to August 2020. A total of 341 nursing mothers and their infants 0 - 12 months of age were recruited. Socio-demographic factors and the different feeding habits of the children were assessed using a semi-structured questionnaire. Nutritional status was assessed using anthropometric measurements. The overall proportion of infants who exclusively breastfed for 6 months was 69.2% and those who were mix-fed were 30.8% in the study area. The overall prevalence of malnutrition in the population was 61.0%. Among the malnourished children, 53.1% were underweight, 19.6% were wasted and 10.0% were stunted. Though not significant, the prevalence of wasting (21.0%) and underweight (58.3%) was higher among Mix-Fed (MF) children when compared to their EBF counterparts. Feeding practices affected the nutritional status of the infants. Underweight and wasting were observed among infants on Complementary Feeding (CF), although some exclusively breast-fed infants were stunted. Hence, nursing mothers should try as much as possible to practice EBF as recommended by WHO and can practice CF when the child is above six months.展开更多

Factors include insufficient oral intake, poor nutrient absorption, and increased metabolic demands. Previous studies have shown high malnutrition rates in hospitalized children due to illness-related metabolic demands, decreased appetite, and inadequate intake. Our objective was to assess the growth and nutritional status of children admitted to King Abdullah University Hospital (KAUH) and identify the prevalence of undernutrition and associated factors. Methods: This prospective, cross-sectional cohort study was conducted at KAUH from July to December 2022. We included children aged 2 months to 16 years, excluding those with conditions altering growth parameters. Data were collected through pediatric data sheets, physical examinations, and laboratory tests. Anthropometric measurements were taken, and growth was assessed using CDC growth charts. Nutritional anemia was defined as hemoglobin 16. Results: A total of 111 patients were included (56.8% male, median age 65 months). Most patients had normal height (82%) and weight (86.5%) upon admission. However, 14.4% were stunted, 11.7% were underweight, 14.4% were overweight, and 3.6% were obese. Growth impairment correlated with higher anemia rates (p = 0.042). Nutritional anemia was present in 12% of patients. No significant relation was found between breastfeeding history and growth retardation, but maternal perception of malnutrition correlated well with actual malnutrition. Conclusion: Our study found a malnutrition prevalence of 19.8%, highlighting the need for systematic nutritional screening in hospitalized children. The study’s limitations include its small sample size and specific patient population, suggesting the need for larger, multicenter studies for more generalizable results.展开更多

Methods We analyzed data from the Chinese National Survey on Students＇ Constitution and Health for the years 1995, 2000, 2005, and 2010 pertaining to Tibetan children and adolescents in Lase （Lhasa）, aged 7-18 years old. Numbers of survey subjects for these years were：2 393, 2 754, 2 397, and 2 643, respectively. Results Our results indicated that the rate of occurrence of stunting in Tibet has evidenced a gradual decline：for boys, from 26.8%in 2000 to 9.3%in 2010;and for girls, from 25.8%in 2000 to 10.8%in 2010. In general, the wasting rate for both boys and girls in Tibet has gradually decreased over time：for boys, from 17.7%in 1995 to 4.6%in 2005;and for girls from 12.5%in 1995 to 2.3%in 2005. The stunting rates of boys aged 7-13 years old and of girls aged 7-11 years old were 67.5%and 53.1%, respectively, while these rates for boys aged 14-18 years old and girls aged 12-18 years old were 32.5%and 46.9%, respectively. Conclusion Stunting and wasting rates of Tibetan children and adolescents indicate a gradual declining trend over time. The stunting rates of both boys and girls during early puberty were significantly higher than those during late puberty.展开更多

The capsid protein（CP） gene of the major outer capsid protein of RRSV was expressed in Escherichia coli BL21（DE3） using the pMAL-C2 X expression vector. The recombinant protein was used as the immunogen to immunize BALB/c mice. A hybridoma cell line 8A12 secreting monoclonal antibody（MAb） against RRSV was obtained by fusing mouse myeloma cells（Sp 2/0） with spleen cells from the immunized BALB/c mice. Western blot analysis showed that the MAb 8A12 can specifically react with RRSV CP. Using the MAb, an antigen-coated-plate enzyme-linked immunosorbent assay（ACP-ELISA）, a dot enzyme-linked immunosorbent assay（dot-ELISA）, and immunocapture-RT-PCR（IC-RT-PCR） assay were developed to detect RRSV. The established ACP-ELISA, dot-blot ELISA and IC-RT-PCR methods could detect RRSV in infected rice tissue crude extracts with dilutions of 1：40 960, 1：1 280 and 1：655 360（w/v, g mL-1）, respectively. The ACP-ELISA and dot-blot ELISA methods could detect RRSV in infected insect vector crude extracts with dilutions of 1：12 800 and 1：1 600（an individual planthopper μL-1）, respectively. The field survey revealed that Rice ragged stunt disease occurs on rice in Hainan, Yunnan, Guangxi, Sichuan, Guizhou, Fujian, Hunan, Jiangxi and Zhejiang in China.展开更多

Methods Data were obtained from the Chinese National Survey on Students＇ Constitution and Health in 1995, 2000, 2005, and 2010 for Chinese-Korean children and adolescents aged 7-18 years. The number of the subjects included was 4789, 4704, 5875, and 5315, respectively. Results The rate of the occurrence of stunting showed a declining trend from 1995 to 2010 （for boys： urban, 6.3%; rural, 12.7% in 1995 and 3.5% for both in 2010. For girls： urban, 7.8%; rural, 13.4% in 1995 and 4.2% and 5.5%, respectively, in 2010）. Although the ratio of wasting did not show significant differences between the urban and rural children and adolescents in 1995, 2000, 2005, and 2010 respectively, the ratio of occurrence of overweight or obesity increased （for boys： urban, 7.3% and 1.3% in 1995, 17.6% and 12.9% in 2010; rural, 7.0% and 1.3% in 1995, 14.6% and 12.8% in 2010, respectively. For girls： urban, 8.1% and 1.0% in 1995, 17.3% and 8.6% in 2010; rural 5.7% and 0.7% in 1995, 16.4% and 7.4% in 2010, respectively）. Conclusion The ratio of malnutrition in children and adolescents in Chinese-Korean areas declined from 1995 to 2010, and the distinction in malnutrition between the urban and rural areas was negligible in 2010. Further, the ratio of overweight and obesity increased over this period.展开更多

Methods Overweight and obesity were defined by age-, sex-, specific BMI reference developed by WHO （2007）, IOTF （2000）, and WGOC （2004）, respectively. Stunting and thinness were defined as height and BMI less than two standard deviations （SD） of the WHO growth reference （2007）, respectively. Data of children and adolescents aged 5 to 19 years （n=54 857, 28 273 boys, 26 584 girls） from the 2002 China National Nutrition and Health Survey （CNNHS） were used in the study. Results The prevalence of overweight, obesity, stunting and thinness among Chinese children and adolescents aged 5-19 years was 5.0%, 1.2%, 13.8%, and 7.4%, respectively when the WHO growth reference （2007） was used, whereas the estimated absolute total number affected by these 4 conditions were 14.6, 3.7, 40.6, and 21.8 million, respectively. The prevalence of overweight and obesity was 18.1% in large cities, while the stunting prevalence was 25.1% in rural 4. Obesity prevalence assessed by the WHO growth reference was higher than that as assessed by the IOTF reference, and obesity prevalence assessed by the WGOC reference was lower than that as assessed by the IOTF reference. Conclusion The nutritional status of children and adolescents is not equal in different areas of China. Stunting is still the main health problem of the poor, while overweight and obesity are the main health problems in large cities.展开更多

文摘The Rural Minimum Living Standard Guarantee(Rural Dibao)is an important unconditional cash transfer program to alleviate poverty in rural China.Despite the importance of children’s nutrition in breaking poverty cycles,little is known about the impact of Rural Dibao on child nutrition outcomes.Using China Family Panel Studies(CFPS),this paper examines the effects of Rural Dibao on child nutrition outcomes and investigates potential pathways and heterogeneous effects.We exploit propensity score matching and difference-in-differences techniques to evaluate the effects of the Rural Dibao program on child nutrition outcomes.Our results suggest that Rural Dibao significantly impacts the nutrition outcomes of children up to 15 years of age.Specifically,our results suggest that Rural Dibao improves child height-to-age z-scores by 1.05 standard deviations and lowers the probability of stunting by 11.9 percentage points.Additional analyses suggest that increased protein intake is the main pathway through which Rural Dibao participation contributes to better nutrition outcomes.We also find that the effect of the program is more pronounced among girls,children who are non-left-behind or live with highly educated mothers,and those from low-income families and poor areas.Our findings suggest that Rural Dibao participation helps improve child nutrition outcomes through improving diet quality.
文摘Appropriate feeding practices are important during infancy for good health, growth and development of infants and children. WHO revised its earlier recommendation of Exclusive Breastfeeding (EBF) of infants from 4 to 6 months of age to EBF until about 6 months of age, with the addition of complementary foods thereafter. This recommendation confirms that breast milk alone is sufficient to meet infants’ nutritional requirements for the first 6 months of life. The main objective of this study was to investigate the effect of various feeding practices on the Nutritional status of infants 0 - 12-month-old in the Kumba 1 Sub-Division. A descriptive cross-sectional study was conducted from December 2019 to August 2020. A total of 341 nursing mothers and their infants 0 - 12 months of age were recruited. Socio-demographic factors and the different feeding habits of the children were assessed using a semi-structured questionnaire. Nutritional status was assessed using anthropometric measurements. The overall proportion of infants who exclusively breastfed for 6 months was 69.2% and those who were mix-fed were 30.8% in the study area. The overall prevalence of malnutrition in the population was 61.0%. Among the malnourished children, 53.1% were underweight, 19.6% were wasted and 10.0% were stunted. Though not significant, the prevalence of wasting (21.0%) and underweight (58.3%) was higher among Mix-Fed (MF) children when compared to their EBF counterparts. Feeding practices affected the nutritional status of the infants. Underweight and wasting were observed among infants on Complementary Feeding (CF), although some exclusively breast-fed infants were stunted. Hence, nursing mothers should try as much as possible to practice EBF as recommended by WHO and can practice CF when the child is above six months.
文摘Introduction: Failure to thrive (FTT) occurs when a child’s growth falls below expected standards, typically due to inadequate nutrient intake. Factors include insufficient oral intake, poor nutrient absorption, and increased metabolic demands. Previous studies have shown high malnutrition rates in hospitalized children due to illness-related metabolic demands, decreased appetite, and inadequate intake. Our objective was to assess the growth and nutritional status of children admitted to King Abdullah University Hospital (KAUH) and identify the prevalence of undernutrition and associated factors. Methods: This prospective, cross-sectional cohort study was conducted at KAUH from July to December 2022. We included children aged 2 months to 16 years, excluding those with conditions altering growth parameters. Data were collected through pediatric data sheets, physical examinations, and laboratory tests. Anthropometric measurements were taken, and growth was assessed using CDC growth charts. Nutritional anemia was defined as hemoglobin 16. Results: A total of 111 patients were included (56.8% male, median age 65 months). Most patients had normal height (82%) and weight (86.5%) upon admission. However, 14.4% were stunted, 11.7% were underweight, 14.4% were overweight, and 3.6% were obese. Growth impairment correlated with higher anemia rates (p = 0.042). Nutritional anemia was present in 12% of patients. No significant relation was found between breastfeeding history and growth retardation, but maternal perception of malnutrition correlated well with actual malnutrition. Conclusion: Our study found a malnutrition prevalence of 19.8%, highlighting the need for systematic nutritional screening in hospitalized children. The study’s limitations include its small sample size and specific patient population, suggesting the need for larger, multicenter studies for more generalizable results.
文摘Objective:To identify the illustration of feeding patterns of stunting children using literature review method.Methods:This study was a descriptive narrative research using literature review approach to explore dietary habits of children with stunting problem.All the literature review processes employed Guideline Review measurement of Joanna Briggs Institute.Related ar ticles in literature were obtained from journal databases,such as Pub Med,Science Direct,Google Scholar,and Dimensions through structured research question with Patient,Exposure an interest,Outcome or response(PEO)methods.Results:This study found 2246 published ar ticles from 2018 to 2021 about children with stunting.Screening process was conducted fur ther to eliminate ar ticles with irrelevant titles and abstracts,and also the unsuitable ar ticles with the research question;hence,about 9 ar ticles were eligible to be reviewed ahead.All these ar ticles mentioned that children with irregular dietary habits would likely experience stunting.The low intake of nutritional food became the major predictor of stunting.Conclusions:Inappropriate feeding patterns and the variety of food were being the factors of stunting emergence among children<5 years of age.High consumption of carbohydrates,less animal-based protein,and misunderstanding about intake of sweetenedcondensed milk predisposed children to suffer stunting.

文摘Objective:To assess prevalence and factors associated with soil-transmitted helminth(STH)infections among rural school children.Methods:This school-based survey applied a cross-sectional design which included children aged 6-14 years enrolled in 12 elementary schools in Banjarwangi,Garut,West Java Province.Stool and blood samples were collected from 388 randomly selected students to examine the STH infections and anemia status,respectively.Anthropometric assessment was performed to profile nutritional status.A structured questionnaire was employed to collect socio-demographic and school performance data.Multivariable logistic regression models were built to assess the factors associated with STH infections in school children.Results:Among 386 schoolchildren,9.8%children were positive for one or more STH infections,predominantly Trichuris trichiura(9.0%),with males(n=23),significantly more infected than females(n=13)(5.9%vs.3.4%,P=0.04).The most infected age group was 6-10 years(n=25,6.5%).The prevalence of STH infection was significantly higher among students that practicing open defecation(n=22,5.7%)(P=0.03).The odds risk of STH infections was associated with practicing open defecation(aOR 2.54,95%CI 1.17-5.53,P=0.02).Conclusions:The findings from this study demonstrate the persistent STH transmission among children underscoring the need for sustained post-MDA intervention strategies in resource-limited settings.
文摘Objective To describe the impact of the global economic crisis on the nutritional status of children in China during and after the crisis.Methods Data from 1990 to 2010 were sourced from the National Food and Nutrition Surveillance System.Approximately 16 000 children under 5 years old were selected using a stratified random cluster method from 40 surveillance sites.Anthropometric and hemoglobin measurements for children under 5 were conducted.Nutritional status was determined according to WHO child growth standards.Results Prevalence of underweight and stunting in children under 5 had a downward trend.Underweight prevalence was close to normal （less than 5%）,with prevalence of stunting 12.6% in 2009 and 12.1% in 2010 in rural areas.Prevalence of stunting in infants under 6 months and 6‐12 months old in poorer rural areas increased from 5.7%‐9.1% and 6.7%‐12.5%,respectively,in 2008‐2009.This trend also continued post‐crisis in 2010.Prevalence of stunting in children left behind by mothers was 20%‐30% higher than in children the same age in general and poorer rural areas.Prevalence of anemia in children did not change in rural areas,but prevalence of anemia in all age groups increased in poorer rural areas,especially in children under 24 months old.Level reached 30%‐40% in 2009,and fluctuated in 2010.Conclusion The nutritional status of children under 5 was comparatively stable during and after the global economic crisis,attributable to the Chinese government＇s policy response.The nutritional status in poorer rural areas fluctuated in response to the economic crisis and,thus,relevant action and intervention must be taken immediately to help the most vulnerable population in poorer rural areas.A proper national nutritional strategy for children under 2 years old,including nutrition supplementation for pregnant women and in‐home fortification for complementary feeding,should be initiated.

文摘Objective To assess the prevalence of malnutrition among children and adolescents in Xizang （Tibet）. Methods We analyzed data from the Chinese National Survey on Students＇ Constitution and Health for the years 1995, 2000, 2005, and 2010 pertaining to Tibetan children and adolescents in Lase （Lhasa）, aged 7-18 years old. Numbers of survey subjects for these years were：2 393, 2 754, 2 397, and 2 643, respectively. Results Our results indicated that the rate of occurrence of stunting in Tibet has evidenced a gradual decline：for boys, from 26.8%in 2000 to 9.3%in 2010;and for girls, from 25.8%in 2000 to 10.8%in 2010. In general, the wasting rate for both boys and girls in Tibet has gradually decreased over time：for boys, from 17.7%in 1995 to 4.6%in 2005;and for girls from 12.5%in 1995 to 2.3%in 2005. The stunting rates of boys aged 7-13 years old and of girls aged 7-11 years old were 67.5%and 53.1%, respectively, while these rates for boys aged 14-18 years old and girls aged 12-18 years old were 32.5%and 46.9%, respectively. Conclusion Stunting and wasting rates of Tibetan children and adolescents indicate a gradual declining trend over time. The stunting rates of both boys and girls during early puberty were significantly higher than those during late puberty.

文摘Rice ragged stunt virus（RRSV） is a serious rice disease in Asia, causing serious yield losses on rice. The capsid protein（CP） gene of the major outer capsid protein of RRSV was expressed in Escherichia coli BL21（DE3） using the pMAL-C2 X expression vector. The recombinant protein was used as the immunogen to immunize BALB/c mice. A hybridoma cell line 8A12 secreting monoclonal antibody（MAb） against RRSV was obtained by fusing mouse myeloma cells（Sp 2/0） with spleen cells from the immunized BALB/c mice. Western blot analysis showed that the MAb 8A12 can specifically react with RRSV CP. Using the MAb, an antigen-coated-plate enzyme-linked immunosorbent assay（ACP-ELISA）, a dot enzyme-linked immunosorbent assay（dot-ELISA）, and immunocapture-RT-PCR（IC-RT-PCR） assay were developed to detect RRSV. The established ACP-ELISA, dot-blot ELISA and IC-RT-PCR methods could detect RRSV in infected rice tissue crude extracts with dilutions of 1：40 960, 1：1 280 and 1：655 360（w/v, g mL-1）, respectively. The ACP-ELISA and dot-blot ELISA methods could detect RRSV in infected insect vector crude extracts with dilutions of 1：12 800 and 1：1 600（an individual planthopper μL-1）, respectively. The field survey revealed that Rice ragged stunt disease occurs on rice in Hainan, Yunnan, Guangxi, Sichuan, Guizhou, Fujian, Hunan, Jiangxi and Zhejiang in China.

文摘Objective To study the nutrition habits among Chinese-Korean children and adolescents in Yanbian Autonomous Prefecture, Jilin, China. Methods Data were obtained from the Chinese National Survey on Students＇ Constitution and Health in 1995, 2000, 2005, and 2010 for Chinese-Korean children and adolescents aged 7-18 years. The number of the subjects included was 4789, 4704, 5875, and 5315, respectively. Results The rate of the occurrence of stunting showed a declining trend from 1995 to 2010 （for boys： urban, 6.3%; rural, 12.7% in 1995 and 3.5% for both in 2010. For girls： urban, 7.8%; rural, 13.4% in 1995 and 4.2% and 5.5%, respectively, in 2010）. Although the ratio of wasting did not show significant differences between the urban and rural children and adolescents in 1995, 2000, 2005, and 2010 respectively, the ratio of occurrence of overweight or obesity increased （for boys： urban, 7.3% and 1.3% in 1995, 17.6% and 12.9% in 2010; rural, 7.0% and 1.3% in 1995, 14.6% and 12.8% in 2010, respectively. For girls： urban, 8.1% and 1.0% in 1995, 17.3% and 8.6% in 2010; rural 5.7% and 0.7% in 1995, 16.4% and 7.4% in 2010, respectively）. Conclusion The ratio of malnutrition in children and adolescents in Chinese-Korean areas declined from 1995 to 2010, and the distinction in malnutrition between the urban and rural areas was negligible in 2010. Further, the ratio of overweight and obesity increased over this period.

文摘Objective To assess the nutrition status of children and adolescents in China using the WHO growth reference （2007） in comparison with that defined by the International Obesity Task Force （IOTF） and the Working Group on Obesity in China （WGOC）. Methods Overweight and obesity were defined by age-, sex-, specific BMI reference developed by WHO （2007）, IOTF （2000）, and WGOC （2004）, respectively. Stunting and thinness were defined as height and BMI less than two standard deviations （SD） of the WHO growth reference （2007）, respectively. Data of children and adolescents aged 5 to 19 years （n=54 857, 28 273 boys, 26 584 girls） from the 2002 China National Nutrition and Health Survey （CNNHS） were used in the study. Results The prevalence of overweight, obesity, stunting and thinness among Chinese children and adolescents aged 5-19 years was 5.0%, 1.2%, 13.8%, and 7.4%, respectively when the WHO growth reference （2007） was used, whereas the estimated absolute total number affected by these 4 conditions were 14.6, 3.7, 40.6, and 21.8 million, respectively. The prevalence of overweight and obesity was 18.1% in large cities, while the stunting prevalence was 25.1% in rural 4. Obesity prevalence assessed by the WHO growth reference was higher than that as assessed by the IOTF reference, and obesity prevalence assessed by the WGOC reference was lower than that as assessed by the IOTF reference. Conclusion The nutritional status of children and adolescents is not equal in different areas of China. Stunting is still the main health problem of the poor, while overweight and obesity are the main health problems in large cities.

文摘The ratoon stunting disease (RSD) of sugarcane,caused by the bacterium Leifsonia xyli subsp.xyli,is one of the major concerns to sugarcane production and breeding programs worldwide.Due to no obvious external symptoms,RSD cannot be easily detected by the growers,hence has reduced the world’s sugarcane production significantly.This study aimed to identify quantitative trait loci (QTL) associated with RSD resistance and to assist in the development of linked molecular markers for marker-assisted breeding to minimize the reduction in sugarcane yield by the RSD infection.A set of 146 individuals derived from a self-crossing of CP80-1827 were evaluated for RSD resistance in a mechanically duplicated inoculated field trial from 2014 to 2017 using tissue blot immunoassay.Leveraging the genetic data and the four years phenotyping data of CP80-1827 selfing population,linkage map construction and QTL analysis were conducted based on clonal F_1 and F_2 mapping population types with GACD V.1.2 and Ici Mapping V.3.3,respectively.A total of 23 QTL associated with RSD resistance were identified,which explained 6%to13%of the phenotypic variation with the two types of software.A total of 82 disease resistance genes were identified by searching these 23 QTL regions on their corresponding regions on the Sorghum bicolor genome (44 genes),sugarcane R570 genome (20 genes),and S.spontaneum genome (18 genes),respectively.Compared with Ici Mapping V.3.3,GACD V.1.2 identified more major (6 vs.3) and stable QTL (2vs.0),and more disease resistance genes (51 vs.31),indicating GACD V.1.2 (clonal F_1 mapping type) is most likely to be more efficient than Ici Mapping (F_2 mapping type) for QTL analysis of a sefling population or clonal F_1 population in clonal species.The identified QTL controlling RSD resistance along with the associated SNP markers will assist sugarcane molecular breeding programs in combating this disease.

文摘Background:B-cell CLL/lymphoma 6(BCL6)is a transcriptional master regulator that represses more than 1200 potential target genes.Our previous study showed that a decline in blood production in runting and stunting syndrome(RSS)affected sex-linked dwarf(SLD)chickens compared to SLD chickens.However,the association between BCL6 gene and hematopoietic function remains unknown in chickens.Methods:In this study,we used RSS affected SLD(RSS-SLD)chickens,SLD chickens and normal chickens as research object and overexpression of BCL6 in hematopoietic stem cells(HSCs),to investigate the effect of the BCL6 on differentiation and development of HSCs.Results:The results showed that comparison of RSS-SLD chickens with SLD chickens,the BCL6 was highly expressed in RSS-SLD chickens bone marrow.The bone marrow of RSS-SLD chickens was exhausted and red bone marrow was largely replaced by yellow bone marrow,bone density was reduced,and the levels of immature erythrocytes in peripheral blood were increased.At the same time,the hematopoietic function of HSCs decreased in RSS-SLD chickens,which was manifested by a decrease in the hematopoietic growth factors(HGFs)EPO,SCF,TPO,and IL-3,as well as hemoglobinα1 and hemoglobinβexpression.Moreover,mitochondrial function in the HSCs of RSS-SLD chickens was damaged,including an increase in ROS production,decrease in ATP concentration,and decrease in mitochondrial membrane potential(ΔΨm).The same results were also observed in SLD chickens compared with normal chickens;however,the symptoms were more serious in RSS-SLD chickens.Additionally,after overexpression of the BCL6 in primary HSCs,the secretion of HGFs(EPO,SCF,TPO and IL-3)was inhibited and the expression of hemoglobinα1 and hemoglobinβwas decreased.However,cell proliferation was accelerated,apoptosis was inhibited,and the HSCs entered a cancerous state.The function of mitochondria was also abnormal,ROS production was decreased,and ATP concentration andΔΨm were increased,which was related to the inhibition of apoptosis of stem cells.Conclusions:Taken together,we conclude that the high expression of BCL6 inhibits the differentiation and development of HSCs by affecting mitochondrial function,resulting in impaired growth and development of chickens.Moreover,the abnormal expression of BCL6 might be a cause of the clinical manifestations of chicken comb,pale skin,stunted growth and development,and the tendency to appear RSS in SLD chickens.
