Objective: To describe the study design, the characteristics of participants as well as the pedigrees included in the baseline survey of Fujian Tulou Family Cohort Study. Methods: Fujian Tulou Family Cohort Study was a prospective open cohort study with a biological sample bank. A baseline survey was conducted in Tulou areas of Nanjing county in Fujian province from 2015 to 2018, including questionnaire survey, physical and biochemical indicators examinations, and blood sample collection in adults aged ≥18 years. In addition, family relationship of the participants was also recorded. The pedigree information of the juveniles under 18 years old were also collected. Results: The baseline survey included 2 727 individuals in two clans, of whom 2 373 (87.0%) were adults, and 2 126 participants completed questionnaires, physical examinations and biochemical tests. The average age of the 2 126 participants was (57.9±13.3) years, with 39.4% being males. The current smoking rates in male and female participants were 41.2% and 2.1%, respectively. The corresponding rates of current alcohol consumption were 19.0% and 2.6%. For common chronic diseases, the prevalence rates were 51.3% for hypertension, 9.7% for diabetes and 26.7% for hyperlipemia according to the self-reported disease diagnoses, health examination results and biochemical examination results in class Ⅱ or Ⅲ hospitals. Based on the family relationship information and genealogical data, 710 pedigrees were finally identified, consisting of 5 087 family members. The numbers of five, four, three, and two generations pedigrees were 3, 88, 238 and 381, respectively. The pairs of the first to the fifth degree relatives were 12 039, 2 662, 1 511, 202 and 31, respectively. Conclusion: The establishment of Fujian Tulou Family Cohort provides valuable resources for exploring the genetic risk factors, environmental risk factors and gene-environment interactions contributing to the risk of common chronic diseases.

OBJECTIVETo analyze the status of maternal health behaviors and it's risk factors for Yi-nationality women in poor rural areas of Sichuan province.

METHODSIn 2012, multi-stage stratified cluster sampling method was used to select 14 villages of two poor counties in Liangshan Yi-nationality autonomous prefecture Sichuan province. At least 10 women who have infants aged 0-12 months were selected in each simple villages, a total of 284. The structured questionnaire was developed on the basis of the theory of reasoned action. Yi-nationality female college students were trained as investigators. Research indicators included prenatal care rate, hospital delivery rate, postpartum examination rate, socio-demographic characteristics, maternal health care knowledge. χ² test was used to compare the differences of above indicators among different groups. The structural equation model were used to statistical analyze.

RESULTSIn the 284 subject women, 51.7% (147/284) women owned more than 2 children, 41.6% (118/284) women were more than 30 years old, 87.3% (248/284) women were illiteracy. The prenatal care rate was 69.7% (197/284), the hospital delivery rate was 26.8% (76/284), and the postnatal check rate was 22.9% (65/284). The influence factors of maternal health behaviors included the number of children, age and education (χ² were 10.92, 13.24, 9.58; P values were 0.027, 0.004, 0.008, respectively).The structural equation model analysis results showed that the maternal health behaviors were directly or indirectly affected by subjective norms (β = 0.236, P < 0.001), women's cognition (β = 0.226, P = 0.020) and women's attitudes on maternal health behavior (β = 0.157, P = 0.001). Among subjective norms, women have high compliance to their husbands (β = 0.850, P < 0.001), their peers (β = 0.708, P < 0.001), and their mothers-in-law (β = 0.636, P < 0.001).

CONCLUSIONThere were still serious problems in maternal health behaviors for Yi-nationality women in poor rural areas. The main factors included not only the women's cognition and attitudes for maternal health, but also the attitudes of important social relationships.

PURPOSE: This study was to explore adaptation experience to family among women who immigrated for marriage. Specific aims were to identify problems immigrant women face as family members and how they interact with other family members. METHODS: Grounded theory methodology was utilized. Data were collected from iterative fieldwork with individual in-depth interviews from 6 immigrant women as key informants, and 2 of their husbands and 2 of their mothers-in-law as general informants. RESULTS: Through constant comparative analysis, a core category emerged as "tearing down the wall in communicating". Causal conditions were feeling frustrated in one's expectations, differences in language and life style, differences in recognition, and perceptions of discrimination and prejudice. Strategies were learning the Korean language, learning Korean culture, managing stress, mediating differences between family members, and introspecting. Intervening factors were support systems, burdens of child-rearing, and the condition of one's health. Consequences were rooting oneself in one's family and accepting one's life as it is. CONCLUSION: Results of the study indicate that there is a need for nurses to understand differences in communication with family members among immigrant women and to provide information and emotional support to improve the adaptation of these women to their Korean families.

PURPOSE: This study was designed to identify the degree of self-image and social support among Korean-Chinese adolescents and investigate the relationship between these variables. METHOD: A total of 621 Korean-Chinese adolescents in five middle schools in YanBian, China were recruited from March 1st to the 9th, 2005. Data was analysed using descriptive statistics, Pearson correlation coefficient, t-test, and ANOVA with the SPSS 11.5 program. RESULT: In Korean-Chinese adolescents, the total self-image score was statistically different for age, parents' education status, parents' job and living with parents. In the 12 subscales, scoresof emotional tone, impulse control, sexuality, social functioning, vocational attitudes and self-reliance had significant differences between groups regarding gender. The total self-image was in the average range. However, areas of mental health and family function were lower than average and the scale of idealism washigher than average. The adolescents perceived parent's support was higher then friend's support. There was a positive correlation between self-image and social support. CONCLUSION: The findings suggest there is a need to examine self-image and social support of Korean- Chinese adolescents according to their parents' marital status and a need to develop a program to help these broken family's adolescents.

OBJECTIVETo explore the quality of life and related social support among people living with HIV/AIDS with related factors.

METHODS331 people living with HIV/AIDS and 148 of their family members were selected using a typical sampling method. Questionnaires on general conditions, tables on history of infection, generic quality of life inventory-74 (GQOLI-74) and social support scale (SSS) were used.

RESULTSData from one-way analysis suggested that people living with HIV/AIDS and their family members with the different sexs, different villages and different cultural backgrounds had differences in GQOLI-74 scores (P < 0.05) while people living with HIV/AIDS with the different villages had differences in SSS scores (P < 0.05). Results from Multiple linear regression analysis revealed that being elderly and negative life events were negatively associated with social support (P < 0.05), while factors as more advanced educational background, harmonious neighborhood relationship and having bother pouring nature were the predictive factors (P < 0.05).

CONCLUSIONMany factors might affect dimensions of quality of life among people living with HIV/AIDS and their family members in rural areas of northern Anhui. Community care and social support of HIV/AIDS should still be greatly enhanced in the countryside of China. A community care mode based on family and neighborhood was expected to be developed.

PURPOSE: The present study was intended to compare difference in research variables between delinquent adolescents and student adolescents, and to analyze discriminative factors of delinquent behaviors among Korean adolescents. METHODS: The research design of this study was a questionnaire survey. Questionnaires were administered to 2,167 adolescents (1,196 students and 971 delinquents), sampled from 8 middle and high school and 6 juvenile corrective institutions, using the proportional stratified random sampling method. Statistical methods employed were Chi-square, t-test, and logistic regression analysis. RESULTS: The discriminative factors of delinquent behaviors were smoking, alcohol use, other drug use, being sexually abused, viewing time of media violence and pornography. Among these discriminative factors, the factor most strongly associated with delinquency was smoking (odds ratio: 32.32). That is, smoking adolescent has a 32-fold higher possibility of becoming a delinquent adolescent than a non-smoking adolescent. CONCLUSIONS: Our findings, that smoking was the strongest discriminative factor of delinquent behavior, suggest that educational strategies to prevent adolescent smoking may reduce the rate of juvenile delinquency. Antismoking educational efforts are therefore urgently needed in South Korea.

Long-lived people may have a unique genetic makeup that makes them more resistant than the general population to prevalent age-related diseases; however, not much is known about genes involved in the longevity. To identify susceptibility variants controlling longevity, we performed a high-throughput candidate gene study using 137 Koreans over 90 yr old and 213 young healthy Koreans. We evaluated 463 informative markers located in 176 candidate genes mostly for diabetes mellitus, cardiovascular disease and cancer under five genetic models. We estimated the odds ratios for each allele, genotype, haplotype, and gene-gene interaction using logistic regression analysis. Associations between 13 genes and longevity were detected at a P-value less than 0.01. Particularly, the rs671 (A) allele of the aldehyde dehydrogenase 2 family (mitochondrial) (ALDH2) gene was associated with longevity only in men (OR 2.11, P = 0.008). Four genes, proprotein convertase subtilisin/kexin type 1 (PCSK1, P = 0.008), epidermal growth factor receptor (EGFR, P = 0.003), paired box 4 (PAX4, P = 0.008), and V-yes-1 Yamaguchi sarcoma viral related oncogene homolog (LYN, P = 0.002) consistently yielded statistical evidence for association with longevity. The findings of the current study may provide a starting point for future studies to unravel genetic factors controlling longevity in Koreans.

OBJECTIVETo identify potential mutations of the FLG gene in two Chinese families affected with ichthyosis vulgaris.

METHODSAll coding exons and exon-intron boundary of the FLG gene were amplified by polymerase chain reaction (PCR) and analyzed by direct sequencing. The results were compared with those of 100 unrelated healthy controls.

RESULTSTwo novel missense mutations, c.1360A>G (p.T454A) and c.10363G>T (p.D3455Y), were detected in all affected individuals from family 1 and family 2 respectively but none of the controls.

CONCLUSIONThe c.1360A>G (p.T454A) and c.10363G>T (p.D3455Y) of the FLG gene may lead to alteration of the structure and function of the FLG protein and cause ichthyosis vulgaris in the two families.

INTRODUCTIONSarcosinaemia is a rare metabolic disorder which has not been reported in Asia.

CLINICAL PICTUREThe urine samples of 2 patients were screened as a routine metabolic screening offered for patients with mental retardation in our hospital. We used gas chromatography-mass spectrometry (GC-MS) which is capable of detecting abnormal pattern in amino acids and organic acids. Plasma sarcosine level was further quantified by GC-MS. The same methods were used in the investigations of asymptomatic family members. Urine examination by GC-MS revealed excessive amount of sarcosine in urine (normally undetectable) and their plasma sarcosine levels were raised. The 2 differential diagnoses of presence of sarcosine in urine--glutaric aciduria type II and folate deficiency--were ruled out by the absence of abnormal organic acids in the initial urine screen and by normal serum folate level respectively. Screening of the 2 families identified excessive sarcosine in urine in 2 siblings, one from each family. However, these 2 siblings of indexed patients thus identified have no neurological or developmental problem.

CONCLUSIONOur finding was consistent with the notion that sarcosinaemia is a benign condition picked up coincidentally during screening for mental retardation.

OBJECTIVEP-glycoprotein 170 (P-gp) is a plausible biologic candidate for pharmacoresistance in epilepsy. The expression and efflux efficiency of P-gp is influenced by a polymorphism (C3435T) in the encoding gene (MDR1). The CC genotype at the MDR1 C3435T polymorphism was reported to be associated with the response to antiepileptic drug treatment. This study attempted to replicate this finding by examining the association of this genetic polymorphism with response to antiepileptic drug treatment in ethnic Han Chinese children with epilepsy.

METHODSTwo hundred and fourteen ethnic Han Chinese children with epilepsy were classified based on the response to antiepileptic drug treatment: drug-nonresponsive and drug-responsive. DNA samples were obtained from the patients. Genotypes of the C3435T polymorphism were determined by traditional polymerase chain reaction followed by restriction digestion (PCR-RFLP). The frequency of genotypes and alleles between the two groups was compared by Chi-square test.

RESULTSOf the 214 patients, 164 were drug-responsive and 50 were drug-nonresponsive. There were no significant differences in the allele frequency and genotype frequency between the two groups.

CONCLUSIONSThere is no an association between the CC genotype or C allele at the locus of C3435T in MDR1 gene and response to antiepileptic drug treatment in ethnic Han Chinese children with epilepsy.
