Objective To explore the speech respiratory characteristics of 7-15 years old children with spastic cerebral palsy and the differences between ordinary children and children with cerebral palsy.Methods The maximum phonation time (MPT) and maximum counting ability (MCA) of 90 ordinary children and 58 children with cerebral palsy aged 7-15 years were measured and a comparison between the 2 groups were conducted.Results (1) Age has significant effects on MPT and MCA of the ordinary children (P ＜0.05).The MPT and MCA of the ordinary children at the age of 7 ～9 years and 10 ～ 12 years are lower than the ones at the age of 13 ～ 15 years.Age has almost no effects on MPT and MCA of children with cerebral palsy(P ＞0.05) ; (2)Sex has no significant effects on MPT and MCA of ordinary children and children with cerebral palsy (P ＞0.05) ; (3) The MPT and MCA of children with cerebral palsy are significantly lower than those of ordinary children (P ＜0.05).Conclusions The MPT and MCA of ordinary children are increased with the growth of age,especially after the age of 13 years,but the children with spastic cerebral palsy do not show that kind of trend and demonstrate a state of retardation of speech respiratory function.Compared with ordinary children,the children with spastic cerebral palsy are easier to suffer from insufficient respiratory support and poor respiratory-phonatory coordination.

OBJECTIVE To explore the absorption mechanism of thiophenorphine, and its effect on P-glycoprotein (P-gp) expression by using Caco-2 cell monolayer model. METHODSThe LC-MS-MS method was applied to determine thiophenorphine concentration in millicell system. The bi-directional permeability studies were performed to investigate the potential involvement of efflux carriers in the intestinal absorption. P-gp inhibition was studied by flow cytometry using calcein-AM as P-gp substrate.The expression of P-gp was evaluated using Western blotting. RESULTSThiophenorphine transport in Caco-2 cells was in time-dependent manner. Its average apparent permeability coefficient (P_(app)) was 2.338×10~(-6) cm·s~(-1). P_(app) was increased 2.8 folds by P-gp inhibitor ciclosporin A, and 2.3 folds by mulitdrug resistance-associated protein2 (MRP2) inhibitor MK571. The accumulation of calcein-AM and the expression of P-gp in Caco-2 cell line wasn't changed noticeably by thiophenorphine. CONCLUSION Thiophenorphine is a common substrate of P-gp and MRP2 and it shows normal transport in millicell system. The expression of P-gp doesn't induce by thiophenorphine.

Objective To establish a system of the screening, evaluation and intervention of congenital heart disease (CHD) in China. Methods All infants (16070) born in Changzhou Maternal and Child Health Hospital from May 1st 2011 to April 30th 2013 were screened for CHD. The infants with CHD were followed up till 1 year of age. Results One hundred and three infants were diagnosed with CHD, and the incidence rate was 0.641%. The top three CHD types in incidences were VSD (0.205%), PDA (0.174%) and ASD (0.10%), respectively. In these infants, 94 cases were followed-up and 9 cases were lost. The incidence of small gapped VSD, ASD and premature PDA were high. Some infants with serious CHD were subjected to surgery, and others were still followed up. Conclusions The incidence of CHD in Changzhou is comparable with that in the whole country. The follow-up can improve the life quality of CHD infants.
