Glycosylation of IgG Associates with Hypertension and Type 2 Diabetes Mellitus Comorbidity in the Chinese Muslim Ethnic Minorities and the Han Chinese.

ABSTRACT: Hypertension and type 2 diabetes mellitus comorbidity (HDC) is common, which confers a higher risk of cardiovascular disease than the presence of either condition alone. Describing the underlying glycomic changes of immunoglobulin G (IgG) that predispose individuals to HDC may help develop novel protective immune-targeted and anti-inflammatory therapies. Therefore, we investigated glycosylation changes of IgG associated with HDC. The IgG N-glycan profiles of 883 plasma samples from the three northwestern Chinese Muslim ethnic minorities and the Han Chinese were analyzed by ultra-performance liquid chromatography instrument. We found that 12 and six IgG N-glycan traits showed significant associations with HDC in the Chinese Muslim ethnic minorities and the Han Chinese, respectively, after adjustment for potential confounders and false discovery rate. Adding the IgG N-glycan traits to the baseline models, the area under the receiver operating characteristic curves (AUCs) of the combined models differentiating HDC from hypertension (HTN), type 2 diabetes mellitus (T2DM), and healthy individuals were 0.717, 0.747, and 0.786 in the pooled samples of Chinese Muslim ethnic minorities, and 0.828, 0.689, and 0.901 in the Han Chinese, respectively, showing improved discriminating performance than both the baseline models and the glycan-based models. Altered IgG N-glycan profiles were shown to associate with HDC, suggesting the involvement of inflammatory processes of IgG glycosylation. The alterations of IgG N-glycome, illustrated here for the first time in HDC, demonstrate a biomarker potential, which may shed light on future studies investigating their potential for monitoring or preventing the progression from HTN or T2DM towards HDC.

Project description:BackgroundNo studies have assessed the association between sleep duration and obesity in Chinese ethnic minorities. Whether the relationship between sleep duration and obesity is different between Chinese Han people and Chinese ethnic minorities remains unclear. The study aimed to explore the relationship between sleep duration and obesity among Chinese Han people and Chinese ethnic minorities.MethodsWe applied data from the Guizhou Population Health Cohort Study (GPHCS), which 9,280 participants were recruited in the baseline survey from 2010 to 2012, and 8,163 completed the follow-up survey from 2016 to 2020. A total of 5,096 participants (3,188 Han Chinese and 1,908 ethnic minorities) were included in the ultimate analysis. Information on sleep duration (total 24-hour sleep time), body mass index (BMI), and waist circumference (WC) was collected at the baseline and follow-up survey, respectively. Cross-lagged panel analyses were conducted to explore the temporal relationship between sleep duration and obesity for Han people and ethnic minorities.ResultsFor Han people, the results from cross-lagged panel analyses indicated that baseline sleep duration was significantly associated with follow-up BMI (βBMI = -0.041, 95% CIBMI: -0.072 ~ -0.009) and follow-up WC (βWC = -0.070, 95%CIWC: -0.103 ~ -0.038), but baseline BMI (βBMI = -0.016, 95% CIBMI: -0.050 ~ 0.018) and baseline WC (βWC = -0.019, 95% CIWC: -0.053 ~ 0.016) were not associated with follow-up sleep duration. In addition, the relationship between baseline sleep duration and follow-up BMI was gender-specific and significant only in the Han people female (βBMI = -0.047, 95% CIBMI: -0.090 ~ -0.003) but not in the Han people male (βBMI = -0.029, 95% CIBMI: -0.075 ~ 0.016). For ethnic minorities, the results indicated that there was no relationship between sleep duration and obesity at all, either from sleep duration to obesity (βBMI = 0.028, 95%CIBMI: -0.012 ~ 0.068; βWC = 0.020, 95%CIWC: -0.022 ~ 0.062), or from obesity to sleep duration (βBMI = -0.022, 95%CIBMI: -0.067 ~ 0.022; βWC = -0.042, 95%CIWC: -0.087 ~ 0.003).ConclusionThe relationship pattern between sleep duration and obesity across Han people and ethnic minorities is different. Future sleep-aimed overweight and obesity intervention should be conducted according to population characteristics.

Project description:BackgroundIn China, there has never been a comprehensive analysis of lung cancer-associated genetic mutations focused on ethnic minorities in the southwestern region. Our study aimed to provide valuable information on lung cancer-associated genetic alterations for cancer diagnosis and treatment, especially in ethnic minorities.MethodsRetrospective data acquisition was conducted spanning 3 years (2016.01-2019.06) among all patients who were diagnosed with lung cancer at the Third Affiliated Hospital of Kunming Medical University Hospital. A total of 5,167 patients including 373 ethnic minorities were included in this study. Propensity score matching (PSM) was used to eliminate the bias between Han and other ethnic minorities, including gender, age, smoking history, metastasis status, clinical stage, histological type, sample type, region, and Xuanwei origin. All tests were two-tailed, and significance was defined as P less than 0.05.ResultsIn terms of the prevalence of EGFR, EGFR L858R, EGFR T790M, ROS1, RET, MET, BRAF, and ERBB2 mutations, there was no significant difference among ethnic groups in Yunnan Province (P>0.05). A higher proportion of EGFR 19 deletion was observed in Hui patients with lung cancer compared with patients of other ethnicities in Yunnan (P=0.048). The prevalence of KRAS mutations was higher in Hani (17.65%, 3/17) and Han patients (11.44%, 80/699) than that in other Yunnan ethnicities (6.04%, 9/149; P=0.07). In Hui patients, ALK fusion was correlated with a history of non-smoking and male gender. In Bai patients, BRAF mutation was also correlated with a history of non-smoking. In all ethnic groups, EGFR mutation was more frequent in women.ConclusionsThis study is the first in-depth large case-control study on genetic mutation profiles among multi-ethnic patients in southwestern China, especially focused on ethnic minorities in this area. Our study may facilitate the understanding of the etiology of this malignant disease and consequently help to reduce the incidence of lung cancer in Yunnan ethnic minority areas.
