Objective To explore the clinical features of respiratory syncytial virus(RSV) pneumonia in full-term neonatal patients.Methods All 422 full-term newborns diagnosed as pneumonia in NICU of Shenzhen Children's Hospital during January 2014 to January 2015 were included in this study.They had been detected for RSV in the way of direct immunofluorescence assay.According to the detection results, they were divided into RSV positive group and RSV negative group, the clinical data in two groups were analyzed.Results Forty-five cases were RSV positive,377 cases were RSV negative.The proportion of breast feeding was 42.22％ vs.65.25％ ,the proportion of cesarean section was 20.00％ vs.76.12％ in two groups,there were significant differences between the two groups.Hospitalization time, birth weight, gestational age, the age of admission showed no difference between two groups.The incidencs of cough (100％), shormess of breath (88.89％), three depressions (48.89 ％), fine rales (66.67 ％), wheezing (22.22％) in RSV positive group were higher than those in the RSV negative group(84.88％ ,42.44％, 13.26％, 13.53％ ,3.98％ respectively), there were significant differences between the two groups.The incidences of fever, saliva, nasal showed no significant difference between the two groups.There was significant difference in the X-ray chest film performance between two groups,RSV positive group was more emhrysema(71.11％ vs.6.9％) ,and less patch shadow(88.89％ vs.93.10％).The laboratory examination of blood routine test, C-reactive protein,respiratory failure, the positive rate of sputum culture, pneumothorax, pleural effusion were without differences.Conclusion RSV is an important pathogen of full-term neonates with infectious pneumonia.Breastfeeding and eutocia can reduce the incidence of RSV infection.Cough, shortness of breath, pulmonary rales, and emphysema in X-ray were common in RSV pneumonia.

Objective To investigate the changes in the expression of macrophage migration inhibitory factor (MIF) mRNA in a rat model of ventilator-induced lung injury.Methods Thirty adult male Sprague-Dawley rats,weighing 2β5-260 g,were randomly divided into 3 groups (n =10 each) using a random number table:control group (group C),small tidal volume (VT) mechanical ventilation group (group S) and large tidal volume mechanical ventilation group (group L).The animals were anesthetized with intraperitoneal ketamine 100 mg/kg,midazolam 0.2 mg/kg and atropine 1.0 mg/kg.The rats were tracheostomized and spontaneous breathing was maintained in group C,while the rats were tracheostomized and mechanically ventilated for 4 h in groups S and L.The tidal volume was 7 ml/kg (group S) or 40 ml/kg (group L),I ∶ E was 1 ∶ 1,RR was 80 bpm and FiO2 was 100％.At 4 h of spontaneous breathing or mechanical ventilation,broncho-alveolar lung lavage fluid (BALF) was collected for determination of the total protein concentration,white blood cell (WBC) counts and concentrations of MIF,IL-6 and IL-1β (by ELISA).Then the rats were sacrificed and the lungs removed for microscopic examination and for determination of wet to dry lung weight ratio (W/D ratio) and expression of MIF mRNA (by RT-PCR).Results Compared with C and S groups,WBC counts,concentrations of total protein,MIF,IL-6 and IL-1β in BALF,and W/D ratio and expression of MIF mRNA in lung tissues were significantly increased in group L (P ＜ 0.05).There was no significant difference in the indexes mentioned above between group C and group S (P ＞ 0.05).The pathological changes occurred in group L.Conclusion The up-regulation of MIF mRNA expression in lung tissues may be involved in the development of ventilator-induced lung injury in rats.

Objective To establish the rabbit model with hepatic VX-2 tumor and to investigate the intake of folate-conjugated silica-coated gold nanorods (GNRs@SiO2-FA) in experimental rabbits. Methods Under CT-guidance, animal model with VX-2 liver cancer was established in 27 rabbits by using puncture inoculation method. CT scanning and sonography were employed to observe the tumor growth. After two weeks, the rabbits were randomly and equally divided into blank control group (n=9, injection of saline), portal vein injection group (n=9, injection of GNRs@SiO2-FA) and intra-tumoral injection group (n=9, injection of GNRs@SiO2-FA). Every three rabbits from each group were sacrificed each time at 24 h, 48 h and 72 h after the treatment. The tumor tissue and the major organs were collected and sent for pathological examination. The cellular uptake of GNRs@SiO2-FA was studied by confocal laser scanning microscopy. Results The rabbit model of VX-2 liver cancer was successfully established. CT and sonography examination indicated that the tumor was rich in blood supply. Confocal laser scanning microscopy revealed that GNRs@SiO2-FA could specifically bind with tumor cells within 24 hours after injection, then the GNRs@SiO2-FA entered into the tumor cells and gathered in the tumor cytoplasm. Conclusion GNRs@SiO2-FA has highly targeted effect on the liver cancer cells in experimental animals, which has very important application prospect in targeting hyperthermia therapy and in 125I seed implantation therapy.

TheLutetium-YttriumOrthosilicate(LYSO)isakindofscintillatingcrystalmaterialwiththebest comprehensive properties. In this work, the trace elements Ca, Fe, K, Li, Mg and Na in LYSO were determined by solution-cathode glow discharge-atomic emission spectrometry ( SCGS-AES ) . The optimal conditions included 0. 1 mol/L HNO3 sample solutions and operation at a voltage at 1080 V with a flow rate of 2. 0 mL/min. The LYSO matrix concentration tolerance of the SCGD source was determined to be 10 g/L. Sample solutions dissolving from several LYSO samples with HF, HNO3 and HClO4 were examined by SCGD-AES. For LYSO samples, the values obtained by SCGD-AES agree well with those obtained by axial inductively coupled plasma-atomic emission spectroscopy ( ICP-AES ) and inductively coupled plasma-mass spectroscopy (ICP-MS). The emissions of Lu and Y were not observed, so that the determination of trace elements in LYSO matrices could be conducted with little interference. The detection limits of Ca, Fe, K, Li, Mg and Na in LYSO were 1. 0, 3. 0, 0. 02, 0. 01, 0. 02 and 1. 0 mg/kg, respectively.
