Objective To assess the nutritional status of critically ill children and the nutritional intake during their stay in pediatric intensive care unit (PICU),and analyze the correlation factors of nutritional deftciencies.Methods One hundred and twenty-seven patients who met the PICU admission standards with a PICU stay of ＞72 h were recruited from June to October 2012 in Shanghai Children's Medical Center.Anthropometric measurements and all nutrition-related indicators of those patients were recorded from day 1 to day 10.Results 59 of the 127 patients (46.5％) showed malnutrition at admission,in which 49.2％ had severe malnutrition.65 of the 127 patients (51.2％) showed malnutrition at discharge,in which 63.1％ were severely malnourished.Median estimated energy requirements (EER) by American Society for Parenteral and Enteral Nutrition was 376.7 kJ/ (kg · d) [interquartile range,IQR:314.0～376.7 kJ/ (kg · d)],prescribed calories were 237.8 kJ/ (kg· d) [IQR:159.5 ～291.8 kJ/ (ks· d)],and delivered calories were 220.2 kJ/ (kg· d)[IQR:132.3 ～ 279.2 k J/ (kg · d)],showing significant difference (P =0.000).The delivered energy was ＜90％ of EER in 80.7％ of the 1021 recorded days and the prescribed energy was ＜90％ of EER in 74.3％of the 1021 recorded days.The cumulative calory deficiency from day 1 to day 10 in PICU was (933.5 ±745.5) kJ/ (kg · person),and the cumulative protein deficiency was (4.0 ±5.0) g/ (kg · person).83 patients (65.4％) experienced at least one feeding interruption.Altogether 170 times of feeding interruption were recorded,of which 117 (68.8％) could be explained by examination procedures.Conclusions There is a high prevalence of malnutrition in critically ill children at admission into PICU,and their nutritional status deteriorates during hospital stay.Discrepancies between required and delivered energy were mainly attributed to under-prescription,while discrepancies between prescribed and delivered energy were mainly attributed to feeding interruptions.Appropriate care for these children entails early nutritional risk screening and correct nutrition support to avoid nutritional deficiencies.

OBJECTIVE: To investigate the effect of inhibiting high mobility group box-1 (HMGB1) gene expression on the invasion and migration of endometrial carcinoma HEC-1A cells by small hairpin RNA. METHODS: Three specific recombinant plasmids of HMGB1 (pshRNA-1 /HMGB1, pshRNA-2 / HMGB1, and pshRNA-3/HMGB1) were transfected into the endometrial cancer cell lines HEC- 1A by lipofectamine (TM) 2000. The expression of HMGB1 mRNA and protein was decteted by RTPCR and Western blot. The invasion and migration abilities of transfected HEC-1A cells were evaluated using Transwell assay and wound healing assay. RESULTS: RT-PCR and Western blot revealed that the expression of HMGB1 at both mRNA and protein levels was significantly inhibited by HMGB1-pshRNA targeting sequence 1, 2, and 3 (P<0.05), and the levels of 3 mRNAs in the transfection group were 0.192±0.006, 0.055±0.002, and 0.123±0.086, respectively, which were significantly lower than those in the Lipo group (0.268±0.008) and the HMGB1/p-NC group (0.270±0.004). The maximum inhibiton rates of the 3 mRNAs were 28.4%, 79.5%, and 54.1%. The levels of 3 HMGB1 proteins in the transfection group were 0.259±0.129, 0.032±0.002, and 0.104±0.007, significantly lower than those in the Lipo group (0.347±0.007) and the HMGB1/p-NC group (0.349±0.007), and the maximum inhibitory rates were 25.4%, 90.8%, and 70.0%. The transwell chamber assay and wound healing assay showed that the invasion and migration of HEC-1A cells were effectively suppressed by inhibiting HMGB1 expression (P<0.05). CONCLUSION pshRNA-HMGB1 can effectively inhibit HMGB1 expression at both mRNA and protein levels, and decrease the invasion and migration of endometrial cancer cells.
