Objective To investigate the correlations of circulating miRNA-205 expression with systemic immune-inflammation index(SII)and systemic inflammation response index(SIRI)in patients with severe obstructive sleep apnea(OSA). Methods The patients who attended the Hypertension Center of the People's Hospital of Xinjiang Uygur Autonomous Region from January to June 2023 and underwent complete overnight polysomnography were consecutively included in this study.Among them,30 patients had severe OSA,and 32 patients did not have OSA.Blood routine tests(white blood cells,neutrophils,monocytes,platelets,etc.)were performed and the expression of miRNA-205 was determined by quantitative reverse transcription PCR.Simple regression was adopted to analyze the correlations among miRNA-205,SII,SIRI,and OSA parameters.The potential regulatory effects of miRNA-205 on OSA and inflammation indices were further evaluated. Results The patients with severe OSA showed lower expression of circulating miRNA-205[1.910(1.240,2.403)vs.3.650(2.148,5.109),z=-3.874,P<0.001]and higher SIRI[1.090(0.775,1.573)vs.0.870(0.650,1.240),z=-2.031,P=0.041]and SII[555.200(451.780,936.350)vs.448.685(380.823,646.073),z=-2.029,P=0.042]than non-OSA patients.In the whole population,apnea-hypopnea index(AHI)showed a negative correlation with circulating miRNA-205(r=-0.391,P=0.002).Among severe OSA patients,each 1-unit increase in AHI was associated with a reduction of 0.030 in miRNA-205 and increases of 10.046 and 0.037 in SII and SIRI,respectively(SII:P=0.003;SIRI:P=0.037).Conversely,each 1-unit rise in miRNA-205 predicted a decrease of 121.093 in SII(β=-0.40,P=0.046).The low expression of miRNA-205 might have a negative moderating effect on elevated SII(β=-0.40,P=0.004). Conclusions Compared with the patients without OSA,those with severe OSA showed elevated SII and SIRI and down-regulated expression of miRNA-205.The low expression of miRNA-205 might have a negative moderating effect on the systemic inflammatory state associated with severe OSA.

Objective:To explore the effects of health education on the knowledge and awareness of hypertension in primary and secondary school students.Methods:Twenty seven primary and secondary schools in Emin County of Xinjiang Uygur Autonomous Region were selected in 2014 as study sites; among which 24 schools were randomly assigned as the intervention group and 3 schools were assigned as control group. According to the education methods (classroom teaching, publicity manual, hypertension class reports and the combination of the three) and the frequency of education (1, 2, 3 times per semester), the intervention group were further randomly divided into 12 subgroups with 2 schools in each group. The intervention study was carried out for 3 years.Results:A total 13 402 students were involved in the study, and there were 11 333 students in the intervention group and 2 069 students in the control group. The awareness rates of hypertension concept [41.8% (4 738/11 333) vs. 24.6% (511/2 069), χ 2=154.86, P<0.01], the adverse consequences of hypertension [85.8% (9 735/11 333) vs. 75.4% (1 561/2 069),χ 2=25.80, P<0.01], the hypertension risk factors [84.3% (9 564/11 333) vs. 72.5%(1 501/2 069), χ 2=12.83, P<0.01), and the health behaviors after hypertension [84.9% (9 629/11 333) vs. 67.7%(1 402/2 069), χ 2=187.24, P<0.01] in intervention group were all significantly higher than those in control group. The stratified analysis showed that among students in elementary school, junior high school and high school, there were significant differences in the awareness rate of adverse consequences [94.4% (2 019/2 138) vs. 81.6% (3 829/4 690), 86.2% (3 887/4 505), χ 2=199.31, P<0.01], awareness rate of risk factor [86.8% (1 857/2 138) vs.86.1% (4 038/4 690), 81.4% (3 669/4 505) , χ 2=49.96, P<0.01); and awareness rate of correct behavior [89.9% (1 923/2 138) vs. 86.1% (4 037/4 690), 81.4% (3 669/4 505) χ 2=89.77, P<0.01]. Up to 95.9% (10 868/11 333) students in the intervention group liked the hypertension health education. Conclusion:Based on the school health education curriculum, the intervention measures of hypertension health education are effective, and the awareness rate of hypertension related knowledge among senior high school students is significantly improved.

Background: The pathogenesis of obstructive sleep apnea (OSA) remains not fully understood. This study aimed to explore the mechanism of OSA by assessing the association between the human tandem of P domains in a weak inwardly rectifying K⁺ channel (TWIK)-related acid-sensitive K⁺ channel-1 (TASK-1) gene and OSA. Methods: A total of 164 patients with severe OSA and 171 patients without OSA were recruited from the Center for Hypertension of People’s Hospital of Xinjiang Uygur Autonomous Region (China) from April to December in 2016. Two single nucleotide polymorphisms (rs1275988 and rs2586886) in the TASK-1 gene were selected and genotyped using a kompetitive allele specific polymerase chain reaction genotyping system. Clinical-pathological characteristics and genotype data were compared between the severe and non-OSA groups to explore the association between TASK-1 gene polymorphism and severe OSA. Results: There were no significant differences in genotype distribution, allele frequency, and the recessive and dominant model of the two selected single nucleotide polymorphisms (rs1275988 and rs2586886) between the severe and non-OSA groups in the total population (P < 0.05). However, for patients with a body mass index (BMI) ≥28 kg/m², the distribution of genotypes and alleles, and the recessive model (GG + GA vs. AA) exhibited significant differences between the severe and non-OSA group (for genotypes: P = 0.014 and P = 0.026; for alleles: P = 0.006 and P = 0.011; for the recessive model: P = 0.005 and P = 0.009, respectively). The simple logistic regression analysis revealed that the GG genotype was a risk factor for OSA. The odds ratio (OR) and 95% confidence intervals (CI) were 4.902 (1.582–15.186, P = 0.006) for rs1275988 and 4.420 (1.422–13.734, P = 0.010) for rs2586886, respectively. In multivariate logistic regression analysis, the combination of GG genotypes of rs1275988 with BMI ≥28 kg/m² increased the risk of severe OSA (OR = 8.916, 95% CI 4.506–17.645, P < 0.001). Conclusion Both the GG genotype of rs1275988 and GG genotype of rs2586886 in the TASK-1 gene may play as potential risk factors in obese patients with OSA.
