ABSTRACT
OBJECTIVE: In order to have a basic understanding of the neglect condition of rural children aged 12 to 17 years old of Tujia and Miao minorities in Wuling mountainous area as well as its causes. METHODS: According to the principle of multistage stratified cluster samplingmethod, a total of 1974 students of eight middle schoolsfrom rural areas in four counties of Tujia-Miao Autonomous Prefecture of Xiangxi had been selected from November to December in 2014( 1020 students from Tujia minority and 954 students from Miao minority). In addition, by adopting themethod of "The Normal Value of Evaluation on the Neglect of Middle School Students from 12 to 17 Years Old in Rural China", the neglect rate and degree can reflect how often and how strong children in rural areas have been neglected. Also, relative factors of the neglect was analyzed by logistic multi-factor regression analysismethod. RESULTS: The total neglect rate of children in rural areas from 12 to 17 years old of Tujia and Miao minorities was 67. 83 %( 1339/1974). The proportion of male students which was 70. 42%( 631/896) was higher than the female students counterpart, which was 65. 68%( 708/1078)( χ~2= 5. 053, P <0. 05). The total neglect degree was( 54. 96 ± 10. 31), and the degree of children between 12 and 14 years old( 55. 45 ± 9. 51) was higher than that of children between 15 and 17 years old( 54. 54 ± 10. 95)( t = 1. 980, P < 0. 05). The neglect rate and degree in medication for female students were higher than male students( χ~2= 10. 233, P < 0. 01, t =2. 139, P < 0. 05), while the neglect rate and degree in education and the neglect degree in security male students had a higher rate and a more severe degree than female students( χ~2= 3. 969, t = 1. 989, t = 2. 014, P < 0. 05). In addition to the neglect of education, the neglect rate and degree of other aspects for children of Tujia and Miao minorities in rural areas had statistical significance( P < 0. 05). The neglect rate of left-behind children was higher than that of un-left-behind children in physical and medical aspects( χ~2= 6. 267, χ~2= 4. 040, P < 0. 05). As theresult of logistic multi-factor regression analysis showed, male students( OR = 1. 292, 95% CI 1. 062-1. 573), children who have less intimate relationship with parents( OR = 1. 344, 95% CI 1. 009-1. 791, OR = 1. 475, 95% CI 1. 063-2. 046), whose parents do not share a close relationship( OR = 1. 396, 95% CI 1. 042-1. 870), those without a single room( OR = 0. 577, 95% CI 0. 464-0. 719) were more likely to be neglected. CONCLUSION: Children of Tujia and Miao minorities in Wuling mountainous area are under a serious neglecting state, and the main influencing factors are whether children have single rooms, the relationship between children and parents and the relationship between parents.

Objective:To discuss the screening results and clinical characteristics of children of Miao and Dong nationalities with mediterranean anemia in ethnic minority areas of Qiandongnan State of Guizhou Province,and to clarify the differences of the mediterranean anemia among different minorities.Methods:A total of 1 623 children of Miao and Dong nationalities with mediterranean anemia in minority areas of Qiandongnan State were selected by multistage stratified random sampling method;quantitative analysis of HbA2 and HbF was used to screen the selected children with mediterranean anemia initially;phenol chloroform extraction method was applied to extract the DNA from the children with mediterranean anemia;ASO/RDB-PCR reverse dot blot hybridization method was used to analyze the gene characteristics of the children with mediterranean anemia.Results:A total of 1 623 children of Miao and Dong nationalities were selected as the subjects.Among 938 children with Miao nationality,there were 18 children with positive α-mediterranean anemia and 36 children with positive β-mediterranean anemia,and the positive detection rate was 1.92%.Among 685 children with Tong nationality,there were 13 children with positive α-mediterranean anemia and 24 children with positive β-mediterranean anemia,and the positive detection rate was 3.50%.The detection rates of composite of α-and β-mediterranean anemia in the children of Miao nationality and Tong nationality were 1.49% and 4.61%.There was no significant difference in the detection rates of different kinds of mealiterranean anemia between two nationalities (P<0.05).The major gene mutations in α-mediterranean anemia were——SEA/-αα and-α3.7,and the major gene mutations in β-mediterranean anemia were CD17/N and CD14-15/N,while the major gene types of the composite of α-and β-mediterranean anemia were——SEA/β41-42 and——SEA/β17.There was no difference in the positive rates of major gene types of different kinds of mediter ranean anemia between two nationalities(P<0.05).Conclusion:There is no difference in the positive rate of children of Miao and Dong nationalities with mediterranean anemia in minority areas of Qiandongnan State.CD17/N,——SEA/-αα and ——SEA/β41-42 are the major gene types of α-,β-,and αβ-mediterranean anemia,respectively.
ABSTRACT
AlM:To determine the group distribution characteristics of lachrymal duct obstruction diseases in major Li Miao minority areas of Hainan province. METHODS: Totally 5 353 residents were selected and researched by randomized cluster sampling in the major Li Miao minority areas of Hainan province. Ocular examination and lachrymal duct flushing were carried out, and questionnaire survey on lachrymal duct obstruction was conducted. The ratio of lachrymal duct obstruction diseases and group distribution characteristics were analyzed based on above research. RESULTS: The prevalence ratios of lachrymal duct obstruction was 4. 47% in major Li Miao minority areas of Hainan province, with 2. 62% in urban area, and 5. 93% in rural area respectively. Prevalence ratios of men and women group were 1. 69% and 6. 39% correspondingly. Difference between the two groups was statistically significant (χ2 = 67. 2821, P = 0. 0000 ). The highest prevalence ratio was 40-69 year-old group, second one was 70-79 year-old group, especially for women in these groups. The prevalence ratios of Ledong, Lingshui, Baisha and Changjiang county were higher than those of Baoting, Qiongzhong county and Wuzhishan city. No significant difference was found between both eyes. CONCLUSlON: ln major Li Miao minority areas of Hainan province, lachrymal duct obstruction mainly occurs in 40-79 year-old patients, with specially higher ratio of women. Statistically, significant difference of the prevalence ratio between urban and rural areas exists. The higher prevalence ratio is attributed to age, gender, geographical location, climate condition, health environment and so on. The prevalence ratio is higher in the dry and windy areas than in the humid and less windy areas.
