Résumé

<p><b>OBJECTIVE</b>Obstructive sleep apnea-hypopnea syndrome (OSAHS) may cause serious morbidities, such as systemic hypertension, diabetes, and cor pulmonale. However, currently no many reports on study of OSAHS in children are available. This study aimed to explore the effects of OSAHS on children's multiple systems.</p><p><b>METHOD</b>A total of 89 cases of children who came to the Sleep Treatment Center in the authors' hospital from March 2009 to December 2010 with snoring were tested with overnight polysomnography (PSG). They were classified into mild OSAHS group (n = 59, mean age of 5.71, SD = 2.46) and moderate to severe group (n = 30, mean age of 5.30, SD = 2.73) based on the PSG results, and 100 healthy children were selected as the control group (n = 100, mean age of 6 years, SD = 2.98). Data including height, weight, body mass index and blood pressure, peripheral blood routine, blood lipids, glucose and insulin, electrocardiogram and echocardiography were collected. Patients' adenoid face and abnormal occlusion were also recorded. Comparisons of the data were made among those groups.</p><p><b>RESULT</b>Mild OSAHS and moderate to severe group had significantly higher prevalence of adenoid face (23.7%, 26.7%), and abnormal occlusion (74.6%, 60.0%) than that in control group (0, 40%) (P < 0.05). There were no significant differences in terms of BMI between the OSAHS group and the control group, but the weight (kg) and height (cm) in the mild OSAHS group (23.3 ± 10.1, 114.9 ± 16.2) and moderate to severe group (21.9 ± 8.4, 110.8 ± 13.3) were lower than those of the control group (31.8 ± 10.1, 136.1 ± 15.1) (all P < 0.05). Compared with the control group, the level of HDL-C (mmol/L)and insulin (mU/L) in moderate and severe group decreased [(1.20 ± 0.30) vs. (1.40 ± 0.27), 2.79 (0.84 - 16.16) vs. 4.92 (0.76 - 16.80), P < 0.05], while the LDL-C (mmol/L) increased [(2.61 ± 0.75) vs. (2.32 ± 0.62), P < 0.05]. The red blood cell counts (× 10(12)/L) and the blood platelet counts (× 10(9)/L) in the mild OSAHS (4.93 ± 0.37, 292.92 ± 75.64) and moderate and severe OSAHS group (5.23 ± 0.22, 292.50 ± 63.05) were significantly higher in contrast to the control group (4.70 ± 0.31, 255.60 ± 69.12) (all P < 0.05), systolic blood pressure (mmHg) in mild group (98.54 ± 10.44) and moderate to severe group (99.13 ± 19.13) was significantly higher compared to control group (87.88 ± 11.37), and the heart rate (beats/min) in moderate to severe group (94.43 ± 10.64) was higher than those in control group (87.12 ± 16.20) (all P < 0.05). The mild OSAHS and moderate and severe OSAHS group had decreased right ventricular internal diameter [(14.24 ± 1.64) mm, (13.17 ± 2.07) mm ], increased main pulmonary artery diameter [(17.05 ± 3.33) mm, (16.33 ± 3.14) mm] and the thickness of right ventricular wall [(3.43 ± 0.26) mm, (3.57 ± 0.20) mm] compared to control group [ (16.10 ± 2.96) mm, (14.11 ± 2.52) mm, (3.32 ± 0.25) mm] (all P < 0.05).</p><p><b>CONCLUSION</b>OSAHS in children may be associated with craniofacial malformations, and may contribute to slow growth and development, elevated blood viscosity and blood pressure, metabolic abnormalities, and change cardiac structure.</p>

Résumé

<p><b>OBJECTIVE</b>To explore the relationship between genetic polymorphisms of CACNA1C that encoded the a1c subunit of the L-type calcium channel and the efficacy of calcium channel blocker (CCB, Nifedipine extended release tablet/20 mg/d) in essential hypertension (EH) patients of Han Chinese in Wenzhou.</p><p><b>METHODS</b>For the enrolled 103 EH patients, Multiplex Polymerase Chain Reaction (Multi-PCR) and matrix assisted laser desorption ionization time of flight MS (MLDI-TOF MS) were performed to detect their genotypes (rs216008, rs1051375, rs2299661, rs10848683, rs215976), blood pressure (BP) after CCB monotherapy was compared among patients with different genotypes.</p><p><b>RESULTS</b>(1) Blood pressure was significantly reduced in all patients post CCB (P < 0.05 vs. pre-CCB). (2) Diastolic blood pressure reduction was more significant in subjects with rs2299661 C/C genotype (wild genotype) than in subjects with rs2299661C/G and rs2299661G/G genotype (mutational genotype) [(12.46 ± 7.91) mm Hg (1 mm Hg = 0.133 kPa) vs. (7.22 ± 8.01) mm Hg and (5.93 ± 9.77) mm Hg, P < 0.05]. (3) Systolic blood pressure reduction was more significant in subjects with rs216008 C/C genotype (wild genotype) than in subjects with rs216008 C/T genotype (mutational genotype) [(20.60 ± 12.35) mm Hg vs. (13.62 ± 10.21) mm Hg, P < 0.05]. (4) Blood pressure reduction was similar between subjects with genotype of rs1051375, rs10848683 and rs215976.</p><p><b>CONCLUSION</b>EH patients with wild genotype of rs2299661 and rs216008 in CACNA1C are more likely to be responders of CCB monotherapy.</p>

Résumé

<p><b>OBJECTIVE</b>To explore etiologic fraction (EF) and interaction of serum hepatitis B surface antigen (HBsAg) carriage and other risk factors for primary hepatocellular carcinoma (PHC) in Wenzhou, Zhejiang, China.</p><p><b>METHODS</b>1:1 matched case-control study was carried out in Wenzhou, with 180 cases of PHC and 180 controls. EF and interactions of serum positive HBsAg [HBsAg(+)] and other risk factors for PHC were analyzed by Mantel-Haenszel stratified method and conditional multiple logistic regression.</p><p><b>RESULTS</b>Serum HBsAg(+), poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events all were risk factors for PHC, with EFs of 0.728, 0.245, 0.224, 0.084, and 0.234, respectively. There existed interactions of HBsAg(+) with other risk factors, including poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events, with etiologic fractions attributable to interaction [EF (A x B)] of 0.770, 0.630, 0.848, and 0.627, and indices of interaction of 0.789, 0.638, 0.852, and 0.634, respectively.</p><p><b>CONCLUSIONS</b>Main risk factor for PHC in Wenzhou, Zhejiang, China could include HBsAg(+), poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events. HBsAg(+) plus any of the following factors, such as poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events, could increase the risk of PHC.</p>
