Conclusion Through the implementation of QCC, the locations of material in the operating room are standardized, and the quality of operating room management and nurses'work efficiency both improved.

Objective To investigate the therapeutic effect of different doses of caffeine on premature apnea.Methods 80 patients with apnea were divided into observation group and control group,each group in 40cases.The two groups applicated caffeine citrate.The control group received the basal dose, first application of 20 mg/kg, intravenous injection, intravenous injection of 5 mg/kg after 24 h.The observation group was treated with intravenous injection of 10 mg/kg after 24 h.The treatment period was 7 d.The therapeutic effect, blood gas and oxygenation index and adverse reactions were observed in the two groups.Results The effective rate of the observation group was 92.5%,which was significantly higher than 75.0% of the control group(x2=4.501,P<0.05).After treatment, the duration[(9.05±1.82)s vs (13.53±2.63)s]and lost time[(2.52±0.94)h vs (3.42±1.13)h]of apnea in the observation group were longer than those of the control group.The number of seizures[(22.15±4.16) vs (33.53±8.48)]was less than that of the control group,the differences were statistically significant(t=8.767,5.434,9.231,all P<0.05).After treatment, PaO2[(84.74±9.74)mmHg vs (71.46±8.53)mmHg],PaCO2[(42.62±4.15)mmHg vs (48.54±5.18)mmHg]and PaO2/FiO2[(221.52±26.51)mmHg vs (197.76±21.71)mmHg]in the observation group were significantly better than those of the control group(t=7.574,4.765,8.643,all P<0.05).The incidence rate of adverse reactions include tachycardia, hyperglycemia, hypoglycemia and restlessness had no significant difference between the two groups (15.0% vs 10.0%, P>0.05).Conclusion In the treatment of premature apnea, advanced caffeine citrate treatment can better improve the clinical symptoms and blood gas index, the curative effect is reliable.

The early of nutritional support (parenteral and enteral) in the very/extremely low birth weight infants improve the survival rate and avoid extrauterine growth restriction.The practice of early nutritional strategy,appropriate enteral feeding and the individualized care and assessment program can result in catch-up growth and avoid growth and development deficits.

Objective To evaluate neurodevelopmental outcome of very preterm(gestational age ＜ 32 weeks) and very low birth weight infant (VLBWI) (weight ＜ 1 500 g) and to examine the effectiveness of an early intervention program till 12 months corrected age.Methods Seventy followed-up very preterms and VLB-WI in Jinan Maternity and Childcare Hospital were enrolled in this study from January 2012 to and were divided into two groups by birth weight.All infants received 20 items of behavioral neurological assessment at 1 to 12 months corrected age and tested mental and psychomotor development with the use of CDCC at 6,12 months corrected age.The preterms who were abnomal in the 20 items of behavioral neurological assessment would receive early intervention (including kinesitherapy, physiotherapy, cereal circulation therapeutic equipment) by physiotherapists and their parents who received an intervention program training and were strongly encouraged to participate in the intervention sessions.The intervention method was adjusted according to the neurological assessment.The SPSS statistical software package for Windows, version 15.0, was used to run Fisher's exact test and t-test on the data presented,and P value of less than 0.05 was regarded as statistically significant.Results The average gestational age of infants was (30.4 ± 1.8) weeks,and average birth weight (1 463.7 ± 307.5) g.The incidence of extrauterine growth restriction was 57.1％ at first follow-up.The incidence of neurodevelpmental impairment NDI) and cerebral palsy tendency at 6 corrected months were 14.3％ ,8.6％ respectively.At 12 months corrected age,the incidence of NDI decreased to 2.9％ and cerebral palsy to 2.9％.There was significant difference in the incidence of NDI between 6 and 12 corrected months.There was no significant difference in the incidence of psychomotor developmental index ＜ 70, mental developmental index ＜ 70, NDI and cerebral palsy between the two groups.Conclusion The early intervention program can improve VLBWI neurodevelopmental outcomes at 12 months' corrected age and reduce the incidence of cerebral palsy.

Objective Radiosensitivity is highly correlated with DNA doub le stra nd breaks(DSBs). The repair of human DSB is possible mainly through nonhomologou s DNA end joining(NHEJ)pathway. This study was designed to determine the relat ionship between expression of 70Ku/ 80Ku prot ein (a modulating subunit of DNA-PK, which is an important component in NHEJ pathway) and radiosensitivity of nasoph aryngeal carcinoma cell lines. Methods Radiosensitivity parameters of the nasoph aryngeal carcinoma cell lines were obtained by the colony forming assay and radi ation dose-survival curve was done by linear quadratic model. Western blot was p erformed to determine the expression of 70Ku and 80 Ku in total extract of CNE1 a nd CNE2 at baseline level、different time after 4?Gy irradiation、12 h after di ff erent doses of irradiation. To perform a semi-quantitated assay of protein expr e ssion, the optic density (OD) value of each band was estimated by automatic imag e analysis system. Results Surviving fraction of CNE1 was higher than those of CNE2 at each dose point. Mean inactivation dose was higher in the CNE1(2.35)t han that in the CNE2(1.11), but the quantity of 70Ku/ 80Ku in either cell line was similar at both baseline and postirradiation levels. Conclusions CNE2 is mo re radiaosensitive than CNE1; as there was no marked correlation observed betwee n the quantity of Ku protein and radiosensitivity of the nasopharyngeal carcinom a cell lines. X-irradiation cannot result in any change in total quantity of Ku protein.
