[Influence of premature rupture of membranes on the early prognosis of extremely premature infants].

Objective: To study the influence of premature rupture of membranes (PROM) on the early prognosis of extremely premature infants, and to provide a basis for the management of extremely premature infants and prenatal consultation.

Methods: A total of 179 extremely premature singleton infants who were born from 2017 to 2019 were enrolled. According to the presence or absence of PROM, they were divided into two groups: PROM group (=69) and non-PROM group (=110).

Acute myocardial infarction in a child with myocardial bridge.

Background: Myocardial infarction (MI) is rare in children, and Kawasaki disease is now recognized as the main cause for MI. In this report, we present a child with MI caused by myocardial bridge (MB).

Methods: A 7.

Isothermal titration calorimetry and 1H NMR studies on host-guest interaction of paeonol and two of its isomers with beta-cyclodextrin.

Thermodynamic parameters of inclusion complex of beta-cyclodextrin (beta-CD) with paeonol and two of its isomers in aqueous solution have been determined with nano-watt-order isothermal titration calorimetry (ITC) and the host-guest inclusion structure has been investigated by using 1H NMR spectra at 298.2 K. The analysis of thermodynamic data reveals that stoichiometry of beta-CD complex with paeonol (Pae) or acetovanillone (Ace) is 1:1 whereas the inclusion complex of beta-CD with 2-hydroxyl-5-methoxyacetophone (Hma) is in 1:1 coexistence with 2:1 stoichiometry.

[A study on acquired immune deficiency syndrome related behaviors in male clients of female sex workers].

Objective: To study the socio-demographic characteristics, acquired immune deficiency syndrome (AIDS) related behaviors of male clients of female sex workers and their determinants.

Methods: Contacting subjects through 5 ways including volunteers of female sex workers (FSWs), sexually transmitted disease (STD) clinics, long-distance bus stations, long-distance cargo station while adopting methods as snowballing, employing an anonymous questionnaire. Data was analyzed by logistic regression analysis.
