Objective To investigate how total parenteral nutrition( TPN) is applied in the neonatal units of the first affiliated hospital of Jinan university, provide reference for the standardized use of TPN, formulate appropriate guidelines, and ensure that clinical nutrition is properly and safely used in prenatal patients. Methods Preterm infants with gestational age<37 weeks and birth weights <2 500 g who used TPN in the neonatal units from January 2012 to June 2013 were assigned into two groups, Patients in Group 1 (n=27) began TPN within 3 d after birth, and patients in Group 2 (n=28) began TPN 3 d after birth. Body weight and the time to regain birth weight were obtained at discharge,, and biochemical indexes before and after TPN were also evaluated. Results Compared with late TPN, early TPN significantly reduce the time to regain birth weight[(12. 5± 7. 2) d vs (8. 9±5. 5) d, P<0. 05], and maintained normal blood glucose level (P<0. 05). There were no differences with regards to length of hospitalization, duration of TPN use, growth rate, blood glucose, K+, Ca2+, Cl-, BUN, serum creatinine, BUN and serum bilirubin (all P>0. 05). Both groups can effectively prevent and correct hypoglycemia and hypocalcemia. Conclusion Early TPN can promote growth of preterm infant. The use of TPN can improve hypoglycemia and hypocalcemia without effect on liver and kidney function. Neither group achieved ideal nutritional support outcome and therefore requires further improvement.

Objective To investigate the method for the treatment of haemorrhage of all ventricles.Methods 46 cases were treated by continuous extrinsic drainage through puncture of the lateral ventricle which accumulated more blood combming with substitution of CSF by meams of lumbus puncture per day.Urokinase was injected into ventricle at regular intervals.Results The symptoms were improved.Head CT were reexamined in 41 cases,which showed disappearance of hematocele in ventricle within 4～15 days.Except for 5 cases of death,other cases recovered from the disease.Conclusion The hematocele above and below the duct in ventricle can be eliminated by this method,and the mortality rate can reduced greatly and the quality of survival can improved.

Objective To establish a quality standard for Aiweixin oral liquid. Methods TLC was applied to the identification of Caryophylli Flos and Crocin in Aiweixin oral liquid. Eugenol was analyzed by GC. Results TLC of Caryophylli Flos and Crocin had distinct separation of characteristic spots and there was no interference in negative comparison. The linear response ranges of Eugenol were between 0.052 17-2.086 8μg (r=0.999 9). The samples were steady within 24 h. The average recovery of eugenol was 95.7%, RSD=1.4% (n=6). Conclusion The method is simple, accurate and reliable, and can be used for the quality control of Aiweixin oral liquid.

Objective To explore the higher dangerous factors,the early clinical performances and its contents of neonatal pulmonary hemorrhage(NPH).Methods The clinical performances,chest radiograms and autoptical pathological materials of 66 cases of newborns who died of NPH at our neonatal department during 1993 to 2003 were reviewed and analyzed.Results The higher dangerous factors of NPH were premature delivery/low birth weight,serious diseases lead to hypoxia and severe infections.The early clinical performances of NPH were the suddenly aggravation of dyspnea and the increasing of moist sounds.The early X-ray performances were lower penetrance of lung fields extensively and well-distributly with path clouds,the intercostals space usually increased.According to the autoptical(patho)-logy,this X-ray perfomance indicated the edema of the pulmonary with small amount of hemorrhage.Conclusion The patients with the higher dangerous factors and the early clinical performances of NPH,must be diagnosed and interfered it as early as possible to reduce the mortality of NPH.

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.

Based on target cycling amplification and 3 ,4 ,9 ,10-perylenetetracarboxylic dianhydride derivative functionalized singal probe, an ultrasensitive electrochemiluminescence ( ECL) sensor was designed for the detection of lead ions. The hairpin substrate DNA was immobilized on the electrode through molecular self-assembly. In the presence of Pb2+and DNAzyme, the substrate was cleaved with single strand DNA fragments left on the electrode surface. Meanwhile, the target and DNAzyme was released for another cleaving circularly. As a result, the single strand DNA fragments hybridized with the assist hairpin probe H1, which leaded to the fabrication of H2 labeled with the 3 , 4 , 9 , 10-perylenetetracarboxylic dianhydride derivative functionalized hollow gold nanoparticles. With the increasing concentration of Pb2+, much more signal probe was been captured and the ECL signal of the biosensor in peroxydisulfate ( S2 O2-8 ) solution would increase. An ECL assay demonstrates that the sensor has a good linear response to Pb2+ concentration in the range of 1í10-12 mol/L-1í10-6 mol/L, with a detection limit of 1í10-12 mol/L. The fabricated sensor shows good selectivity toward Pb2+against other common metal ions.

Objective To explore the effects of application of laparoscopic simulators in teaching of plastic surgery. Methods 10 plastic surgeons and 20 standardized training surgical residents with 2 to 4 years' experience were tested about their proficiency in moving beans, pinching, suturing and tying by timing and counting. After they were trained with laparoscopic simulators 3, 6, 9 times with each time for 90 min, tests were taken. SPSS 19.0 was used to make single factor variance analysis of the related data or conduct q test. Result There was significant difference before and after the residents' training of moving beans, pinching, suturing and tying (P<0.05). Less time to finish the operation was needed after training, but after training for 6 times or 9 times, there was no significant difference in operation time (P >0.05). Conclusion Application of laparoscopic simulator training can significantly improve the operation skills of the novices with some clinical experience in the short term, which is conducive to the endoscope assisted breast augmentation surgery, and is worthy of promotion.
