Objective: We aimed to compare the perinatal outcomes in late preterm spontaneous and indicated birth neonates. Methods: We studied 289 late preterm births, classified as either aspontaneous late preterm birth (sLPTB) group (preterm labor with intact membranes and preterm premature rupture of membranes) or an indicated late preterm birth (iLPTB) group (hypertensive disorder in pregnancy, placental causes, and maternal diseases), according to the delivery indication. We then compared the maternal and neonatal characteristics and perinatal outcomes, including the Apgar score, admission to the neonatal intensive care unit (NICU) or special care nursery (SCN), duration of NICU stay, and the rate of composite morbidity (antibiotic use, hypoglycemia, hypocalcemia, hyperbilirubinemia requiring phototherapy, respiratory support, and respiratory distress syndrome). Results: A total of 198 neonates were in the sLPTB group and 91 were in the iLPTB group. In spite of greater gestational age at the time of delivery in the iLPTB group, the mean birth weight was lower than that in the sLPTB group. Additionally, the iLPTB group showed lower Apgar scores, and higher rates of NICU or SCN admission, respiratory support, and hypoglycemia, but there was no difference in the rate of composite morbidity between the two groups. Conclusion: iLPTB neonates had lower birth weights despite greater gestational age than those in the sLPTB group, but there was no difference in the rate of composite morbidity between the two groups.

Background There are limited data comparing long-term clinical outcomes between first-generation (1G) and second-generation (2G) drug-eluting stents (DESs) in patients who underwent successful percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO) lesion. Methods A total of 840 consecutive patients who underwent PCI with DESs for CTO lesion from January 2004 to November 2015 were enrolled. Finally, a total of 324 eligible CTO patients received 1G-DES (Paclitaxel-eluting stent or Sirolimus-eluting stent, n = 157) or 2G-DES (Zotarolimus-eluting stent or Everolimus-eluting stent, n = 167) were enrolled. The clinical endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), total repeat revascularization [target lesion revascularization (TLR), target vessel revascularization (TVR), and non-TVR]. We investigated the 5-year major clinical outcomes between 1G-DES and 2G-DES in patient who underwent successful CTO PCI. Results After propensity score matched (PSM) analysis, two well-balanced groups (111 pairs, n = 222, C-statistic = 0.718) were generated. Up to the 5-year follow-up period, the cumulative incidence of all-cause death, re-MI, TLR, TVR and non-TVR were not significantly different between the two groups. Finally, MACE was also similar between the two groups (HR = 1.557, 95% CI: 0.820–2.959, P = 0.176) after PSM. Conclusions In this study, 2G-DES was not associated with reduced long-term MACE compared with 1G-DES following successful CTO revascularization up to five years.

Background Central blood pressure （BP） is pathophysiologically more important than peripheral BP for the pathogenesis of cardiovascular disease. Arterial stiffness is also a good predictor of cardiovascular morbidity and mortality. The effects of benidipine, a unique dual L-IT-type calcium channel blocker, on central BP have not been reported. This study aimed to compare the effect of benidipine and Iosartan on the central BP and arterial stiffness in mild to moderate essential hypertensives. Methods This 24 weeks, multi-center, open label, randomized, active drug comparative, parallel group study was designed as a non-inferiority study. The eligible patients （n=200） were randomly assigned to receive benidipine （n=101） or Iosartan （n=99）. Radial artery applanation tonometry and pulse wave analysis were used to measure the central BP, pulse wave velocity （PWV） and augmentation index （AIx）. We also measured the metabolic and inflammatory markers. Results After 24 weeks, the central BP decreased significantly from baseline by （16.8±14.0/10.5±9.2） mmHg （1 mmHg =0.133 kPa）（systolic/diastolic BP; P 〈0.001） in benidipine group and （18.9±14.7/12.1±10.2） mmHg （P 〈0.001） in Iosartan group respectively. Both benidipine and Iosartan groups significantly lowered peripheral BP （P 〈0.001） and AIx （P 〈0.05）, but there were no significant differences between the two groups. The mean aortic, brachial and femoral PWV did not change in both groups after 24-week treatment. There were no significant changes of the blood metabolic and inflammatory biomarkers in each group. Conclusion Benidipine is as effective as Iosartan in lowering the central and peripheral BP, and improving arterial stiffness.

The aim of this study is to investigate the causal relationships between key factors relating to education that affect the happiness of adolescents, and to put forward policy suggestions wherewith 20 OECD countries may raise their levels of adolescent happiness. The HBSC score of adolescents from 20 OECD countries was selected as an indicator for happiness, and a number of independent variables such as per capita GDP and per capita educational expenditure were included in the analysis. A structural equation model was employed for the analysis. The research results show that the variables that directly affected happiness were per capita educational expenditure, educational decentralization level, number of students per teacher, and others. Of these, per capita educational expenditure had the greatest influence. Of the paths to adolescent happiness, those that contained a significant indirect effect were ＂per capita GDP → per capita educational expenditure → happiness＂ and ＂educational decentralization → number of students per teacher → happiness＂, which were significant at the level ofp 〈 0.05. Compiling the paths toward adolescent happiness focusing on the significance of these direct and indirect effects shows that the ＂per capita GDP →per capita educational expenditure → happiness＂ path has the greatest effect.

＜正＞In this paper, the permanent magnet synchronous generator of 1.5MW output power which is driven directly without gear system is designed by conventional magnetic equivalent circuit method and analyzed by finite element method for verification of design. We analyzed the characteristics of generator like no load, rated load, short circuit condition and demagnetization of permanent magnet. The last, the analysis results of two kinds of rotor types are compared with each other. Especially the THD （total harmonic distortion） of output voltage is examined for the comparison.

AIM： To investigate the efficacy of combined topical 0.05% cyclosporine A（CsA; Restasis~？, Allergan pharmaceuticals, USA） and 0.1% sodium hyaluronate treatment in dry eyes with meibomian gland dysfunction（MGD）.METHODS： In a retrospective analysis, 53 patients（106 eyes） with MGD were enrolled and performed lid warm massage for 10 min daily and be instilled preservative free sodium hyaluronate 0.1% eye drops 4 times daily. Patients were divided into subjects treated with topical 0.05% CsA and preservative free sodium hyaluronate vehicle（experimental group, n=74 eyes） and subjects treated with the preservative free sodium hyaluronate vehicle（control group, n=32 eyes）. They were evaluated at baseline and 1, 2, and 3 mo for subjective symptoms and objective signs including tear film break-up time（t BUT）, Schirmer test, corneal staining（CS） score, lid margin telangiectasia（LMT）, meibomian gland secretion（MGS）, and conjunctival injection（CI）.RESULTS： In the short-term treatment, the experimental group showed a statistically significant improvement in the ocular surface disease index（OSDI; P〈0.001）, tBUT（P=0.004）, Schirmer test score（P=0.008） and LMT（P=0.021） by repeated measure ANOVA. Additionally, mean changes from baseline in OSDI（P〈0.001）, tBUT（P=0.001）, Schirmer test score（P=0.029）, CS score（P=0.047）, LMT（P=0.002）, CI（P=0.030） were improved better in the experimental group than in the control group at 3 mo. However, there was no significant difference between the two groups in MGS（P=0.67）.CONCLUSION： In dry eyes with MGD, 0.05% CsA improves the tear film stability as well as subjective ocular discomfort, and is effective in controlling lid margin inflammation.
