Correlation between single nucleotide polymorphism of FCRL-3 gene and Graves' disease in Han population of northern Anhui province, China.

ABSTRACT: OBJECTIVE:The frequency distribution of A/G genotype at position-169 in promoter of FCRL3 gene (Fc receptor-like 3) was identified in Han population of northern Anhui Province. The correlation between single nucleotide polymorphism (SNP) at this site and genetic susceptibility of Graves disease (GD) was discussed. How the genotype at this position correlated to age, gender, severity of goiter, presence or absence of exophthalmos, levels of thyrotrophin receptor antibody (TRab), thyroid peroxidase antibody (TpoAb) and anti-thyroglobulin antibody (TgAb) and thyroid function was analyzed in details. METHOD:Peripheral venous blood was collected for DNA extraction. SNP at position-169 in the promoter of FCRL3 gene was determined by using PCR-RELP among 180 GD cases and 146 normal subjects. Thyroid function tests and antibody detection were performed. RESULTS:The frequency of GG genotype of position-169 in promoter of FCRL3 gene was higher in GD group than in control group. The frequency was 28.9% and 13.8%, respectively, showing significant differences in intergroup comparison (?(2)=6.618, P=0.046). The G allele frequency of GD group and control group was 49.4% and 40.4%, respectively, also showing significant differences between the groups (?(2)=5.308, P=0.021). GD cases with AA, AG and GG genotypes at position-169 in FCRL3 promoter had significant differences in serum level of TRAb (?(2)=7.319, P=0.026). However, no significant differences in gender, severity of goiter, TpoAb and TgAb level, presence or absence of exophthalmos and thyroid function (FT3, FT4, TSH) were found between the three genotypes (P>0.05). CONCLUSION:A/G SNP at position-169 in promoter of FCRL3 gene was correlated with susceptibility to GD among Han population in northern Anhui Province. G allele may contribute to the susceptibility to GD and correlate to positive TRAb result in thyroid diseases, but not to age of onset, gender, presence or absence of exophthalmos, thyroid function, TpoAb and TgAb level or severity of goiter.

Project description:BackgroundAnhui Province in China is facing a severe HIV epidemic with an increasing number of newly diagnosed cases.MethodsIn this study, HIV genetic characteristics in the province were investigated. Newly reported HIV-positive individuals from 15 districts of Anhui Province were enrolled and interviewed. Total viral RNA was extracted from plasma isolated from blood samples. We amplified and sequenced an HIV pol fragment of the 1062 bp. The sequences were used for determination of HIV subtypes and the presence of drug resistance mutations. Transmission networks were constructed to explore possible relationships. And all of assembled partial pol genes were submitted to the Stanford HIV Drug Resistance Database website to find the transmitted drug resistance.ResultsPartial pol gene sequences were obtained from 486 cases. The results showed that MSM was the most dominant transmission route (253, 52.06%), followed by heterosexual transmission (210, 43.21%) and blood-borne transmission (1, 0.21%). Many subtypes were identified, including CRF01_AE (226, 46.50%), CRF07_BC (151, 31.07%), subtype B (28, 5.76%), CRF08_BC (20, 4.12%), CRF55_01B (15, 3.09%), CRF68_01B (7, 1.44%), CRF67_01B (3, 0.62%), CRF57_BC (2, 0.41%), CRF59_01B (2, 0.41%), CRF79_0107 (2, 0.41%), subtype C (2, 0.41%), CRF64_BC (1, 0.21%), and circulating recombinant forms (URFs) (27, 5.55%). Four transmission subnetworks containing high transmission risk individuals (with degree ≥4) were identified based on CRF01_AE and CRF07_BC sequences, including two CRF01_AE transmission subnetworks constituted by elderly people with average ages of 67.9 and 61.5 years. Infection occurred most likely through heterosexual transmission, while the other two CRF07_BC transmission subnetworks consist mainly of MSMs with average ages of 31.73 and 34.15. The level of HIV-transmitted drug resistance is 3.09%.ConclusionsThe simultaneous spread of multiple HIV subtypes in Anhui province underscores that close surveillance of the local HIV epidemic is necessary. Furthermore, the elderly people were frequently involved, arguing for behaviour intervention in this specific population besides the MSM risk group.

Project description:ObjectiveWe aimed to explore the correlation between functional disability and quality of life (QoL). And exploring the interaction of functional disability, basic demographic characteristics and health-related information on QoL among the rural elderly in Anhui Province.MethodsThis study used multi-stage stratified cluster sampling in rural Anhui Province from January to July 2018 to conduct a cross-sectional survey of older adults who met the inclusion criteria. The Five-Dimensional European Quality Of Health Scale (EQ-5D) and the WHO Disability Assessment Schedule (WHODAS2.0) scale were used to evaluate the QoL and functional disability, and the basic demographic characteristics of the survey subjects were also collected. Using binary logistic and Classification and regression tree model (CART) models to analyze the data, explore the relationship between functional disability and QoL in the elderly.ResultsA total of 3491 older adults were included in the survey, and 3336 completed the entire survey, with an effective response rate of 95.56%. After adjusting for covariables, those who had limited in dimension of mobility (AOR=2.243, 95%CI: 1.743-2.885), getting along (AOR=1.615, 95%CI: 1.173-2.226), life activities (AOR=2.494, 95%CI:1.928-3.226), and social participation (AOR=2.218, 95%CI: 1.656-2.971) had a lower QoL. However, the dimension of cognition (AOR=0.477, 95%CI: 0.372-0.613) is a protective factor for QoL. Additionally, we also observe that 96.3% of those who were unemployed and limited in both mobility and life activities dimensions had a lower QoL, but among those who were robust in both mobility and social participation dimensions and not suffer from chronic diseases, 56.3% had a higher QoL.ConclusionsOur findings indicate that special attention should be paid to the elderly who are unemployed, have limited in cognition, getting along, social participation, mobility, life activities and cognition robust to improve their QoL. This research is of great significance for formulating targeted strategies and measures to improve the QoL for rural elderly.
