Background Rapamycin(RAPA)is a specific inhibitor of the mammalian target of rapamycin (mTOR).Researches showed that RAPA inhibits the proliferation of lens epithelium cells(LECs)and tumor cells and induces apoptosis of tumor cells.To investigate whether rapamycin has the inhibitory effect on retinal pigment epithelium(RPE)cells is very important for the prevention and management of proliferative vitreoretinopathy (PVR).Objective This study was to investigate the effects of RAPA on the proliferation and apoptosis of human RPE cells in vitro.Methods Human RPE cells(D407 strain)were cultured and passaged and then divided into regular culture group(blank control group),DMSO control group(0.1‰ DMSO +regular culture),and different concentrations RAPA-treatment groups(5,10,20,40,80,160,320 nmol/L).The proliferation(A490)of human RPE cells was detected using MTT,and the inhibitory rates of RAPA on the proliferation of RPE cells were calculated and compared among different groups at 12,24 and 48 hours.The apoptosis rates of the cells were analyzed among various groups by Hoechst staining after 12,24,48 hours.Results The inhibitory rates of RAPA on RPE cells were significantly different among various groups(F=484.451,P＜0.01)and evidently elevated in 20-320 nmol/L RAPA groups compared with DMSO control group(P ＜ 0.01).The inhibition of RAPA on the cells was considerably enhanced as the lapse of time(F=232.262,P＜0.01)with more dominant effects in 24 and 48 hours compared to 12 hours after addition of RAPA(P＜0.05-0.01).Compared with blank control group and DMSO control group,the apoptotic rates of the cells were evidently increased in 12,24,48 hours in 10 nmol/L RAPA group(all P＜0.05),and higher cellular apoptotic rates were found in 20-320 nmol/L RAPA groups(all P＜0.01).The alteration of cellular apoptotic rate showed a gradually incremental trend as the acting time of RAPA(F =625.584,P＜0.01).Karyorrhexis and mass-like density staining and chromatin substance were seen in RPE cells under the fluorescence microscope in ≥ 10 nmoL/L RAPA groups.Conclusions RAPA suppresses the proliferation and induces the apoptosis of human RPE cells in concentration-and time-dependent manner in vitro.

ObjectiveTo explore clinical features of cerebral palsy of premature infants and attempt to deduce the etiology and time of brain damages.MethodsMaterials included perinatal risk factors, neurodevelopmental evaluation, types of cerebral palsy and CT or MRI findings of 281 cerebral palsied children embryo age less than 37 weeks were analyzed retrospectively.ResultsAmong 281 cases, 47.07% of them were premature infants and most of them (64.67%) suffered from multiple high risk factors especially during perinatal and post neonatal periods. The main causes were perinatal asphyxia, icterus, and twin pregnancy. Spastic diplegia was more common in this group (70.81%), followed by athetosis and mixed of spastic and athetosis. The characteristic of neuroimaging findings was periventricular leukomalacia (PVL).ConclusionFor cerebral palsy of premature children, pematurity is an important cause of cerebral palsy and brain damages are often occurred during perinatal and post neonatal periods, main type is spastic diplegia, and main pathological change is PVL.

Objective To explore the difference of the professional self-concept in nursing staff of gynecology and obstetric department with the different career motivations in a three-level general hospital.Methods A total of 97 nurses were selected and investigated with professional self-concept scale and career motivation questionnaire.Results Among 97 nurses,44 nurses voluntarily chose the nursing job and their score of professional self-concept and job satisfaction was ( 3.04 ± 0.36),(2.91 ± 0.53 ),respectively.Fifty-three nurses passivity chose the nursing job by external factors and their score of professional self-concept and job satisfaction was(2.89 ± 0.29),(2.49 ± 0.53 ),respectively,and the difference between the two group was statistically significant (t =2.295,3.868,respectively ; P ＜ 0.05 ).Scores of two groups except job satisfaction score in 53 nurses group were more than 2.5 and 2.5 was a level boundary value.Conclusions Nurses with different career motivation have different professional self-concept.It is important for nursing educator to pay attention on cultivating nurse students' professional interest and career motivation.

OBJECTIVEThis study was undertaken to investigate the clinical features of oral motor dysfunction and feeding problems as well as the nutritional status of children with cerebral palsy (CP).

METHODSFifty-nine CP children, 39 boys and 20 girls, mean age 31 months (20 to 72 months), were recruited. Their parents were interviewed for high risk factors and feeding history. Each case was assessed for oral motor and feeding problems based on oral motor and feeding skill score; for nutritional status by measurement of weight, height; neurologically for type of cerebral palsy and for developmental age by Gesell's developmental scale. Equal number of age and sex matched controls were included for comparison of nutritional status, oral motor and feeding skill score.

RESULTSAmong 59 patients, 51 cases had oral motor dysfunction and 55 cases had feeding problems including all athtosis, spastic tetraplegia, and 16 had spastic diplegia. The scores of both the mean oral motor function and feeding skill of CP children were significantly lower than those of the controls (P < 0.001). Main food of children with cerebral palsy consisted of liquid and semisolid diet. Body weight and height below the 25th percentile were found in 13 cases and 19 cases, respectively.

CONCLUSIONSThe majority of the children with cerebral palsy had oral motor dysfunction and feeding problems which appeared in early age and disturbed the growth and nutritional status. Thorough assessment for oral motor function, feeding problems and nutritional status of CP children is indicated in order to start timely rehabilitation and nutritional interventions which can significantly improve their nutritional status and quality of life.
