OBJECTIVE: To investigate the significance of tumor necrosis factor-alpha (TNF-α) and plasma endothelium (ET) in pathophysiologic process of patients with obstructive sleep apnea hypopnea syndrome(OSAHS) with type 2 diabetes mellitus (T2DM). METHOD: All observed subjects were divided into 4 groups. A number of 80 patients with OSAHS, 65 cases of OSAHS with T2DM patients, 20 patients with T2DM, and 32 cases of healthy control group were observed in this study. The serum levels of TNF-α and ET were detected by double antibody sandwich ELISA, the content of TNF-α and ET were compared between OSAHS group and OSAHS + T2DM group. It were also compared before and after treatment of CPAP or surgery. RESULT: TNF-α level is higher in OSAHS+T2DM group than that in the OSAHS group, T2DM group and the control group (P < 0.05); TNF-α level in OSAHS group and the T2DM group are higher than that in the control group (P < 0.05), but there was no difference in TNF-α level between the OSAHS group and the T2DM group. There was also no difference in ET level of the four groups. There were significant differences of TNF-α before and after treatment of CPAP or surgery in OSAHS group and OSAHS+T2DM group (P < 0.05). But there was no significant differences of ET before and after treatment of CPAP or surgery in the OSAHS+T2DM group (P > 0.05). CONCLUSION TNF-α may be involved in the development of OSAHS and T2DM, while ET may have little effect on the occurrence and development of OSAHS and T2DM.

Objective:To evaluate the effects of quality improvement (QI) program on the incidence of bronchopulmonary dysplasia (BPD) in very preterm infants (VPIs) [gestational age (GA)<32 weeks].Methods:From July to December 2017,VPIs admitted to the Department of Neonatology of Yancheng Maternity and Child Health Care Hospital were retrospectively enrolled and were assigned into pre-quality improvement program group (Pre-QI group).From July to December 2018, VPIs were assigned into post-quality improvement program group (Post-QI group). QI program included delayed umbilical cord clamping (DCC), early postnatal nasal continuous positive airway pressure ventilation (nCPAP) and minimally invasive pulmonary surfactant therapy (MIST). The clinical data and prognostic indicators of the two groups of VPIs and their mothers were compared. Independent sample t-test or continuity-adjusted Chi-square test (or Fisher's exact test) and Logistic regression were used for statistical analysis. Results:A total of 204 VPIs were enrolled, including 96 cases in Pre-QI group and 108 cases in Post-QI group. 1 min Apgar score and hematocrit on admission to the neonatal intensive care unit (NICU) in the Post-QI group were significantly higher than the Pre-QI group( P<0.05). The incidence of delivery room resuscitation, endotracheal intubation at birth and endotracheal intubation in NICU in the Post-QI group were significantly lower than the Pre-QI group( P<0.05). The application of pulmonary surfactant and mechanical ventilation, the incidence of neonatal respiratory distress syndrome and BPD in the Post-QI group were lower than the Pre-QI group ( P<0.05). After adjusting for confounding factors, Logistic regression analysis showed that DCC ( aOR=0.261,95% CI 0.091~0.718, P=0.023), nCPAP ( aOR=0.284,95% CI 0.123~0.667, P=0.015), MIST ( aOR=0.276,95% CI 0.114~0.627, P=0.011) were protective factors of BPD, and MV ( aOR=2.023,95% CI 1.048~3.918, P=0.036) was risk factor of BPD. Conclusions:The QI program consisting of DCC, early nCPAP and MIST for VPIs can reduce the incidence of BPD.
