Some studies have shown that compared with pressure-support ventilation,NAVA can improve patient-venti-lator synchrony while maintaining spontaneous breathing,unload respiratory musculaturei n term adn prte erm i nfants.Further studies are needed to determ ine whether NA VA will have significant impact on the overall outcomes of neonates.

Objective: In this paper, a method of gas chromatography mass spectrometry for determination of free resveratrol in grape wine was established. Methods: After evaporated to eliminate ethanol, sample of grape wine was extracted with ethyl acetate, and evaporated again to dryness. The residues were derivatized with N,O bis (trimethylsianyl) trifluoroacetamide plus 1% trimethychlorosilane. Then, qualitative and quantitative analysis of cis and trans resveratrol were carried out using GC MS scan mode. Results: The average recoveries were 85.6%-110.5%,and the relative standard deviations were 8.2%-11.5%, when resveratrol was added to grape wine at 0.25-1.25 mg/L levels. The correlation coefficient was 0.995 in range of 0.50-10.00 mg/L. The detection limit for resveratrol in grape wine was 0.005 mg/L. Further 15 grape wines made in China were analyzed. The contents of cis resveratrol were 0.02 -0.56 mg/L and trans resveratrol were 0.15-1.28 mg/L. Total resveratrol were 0.26-1.48 mg/L. Conclusion: This assay is accurate and reproducible for determination of free resveratrol in grape wines.

Methods Using semi-RT-PCR and immunohistochemistry technique, specimens from 63 patients of breast cancer,20 of fibroadenoma were detected for expression of VCAM-1.Microvessel density(MVD) was counted by endothelial cells immunostained using monoclonal antibody CD34.Circulating sVCAM-1 concentrations were measured by enzyme linked immunosorbent assay. Results Of 63 breast cancer tumor tissues VCAM-1 mRNA was detected in 37 cases. The rate of VCAM-1 mRNA in the primary breast cancer tissues were significantly higher than that in the adjacent non-cancerous tissues and benign fibroadenoma tissues (?2=43,P

Objective To investigate the characteristics of apparent diffusion coefficient (ADC)values in the normal fetal kidney and to explore the normal data reference of fetal kidney by using diffusion-weighted imaging (DWI).Methods 71 normal kidneys of fetuses confirmed by ultrasound and MR were examined with DWI with four b values of 100 s/mm2 ,200 s/mm2 ,500 s/mm2 and 700 s/mm2 ADC values of the symmetrical ROIs were compared between left and right kidney for each b value.While ADC values between different group in ipsilateral kidney were compared between different b values.And the relationship between ADC values and gestational age was also evaluated.Results When b = 100 s/mm2 ,there was a statistically significant difference between the ADC value of left and right kidney,and the remaining group showed no statistically significant differences between the ADC values of left and right kidney.Comparisons among different b values of ipsilateral kidney showed statistically significant differences among the groups with different b values except the comparison between b=100 s/mm2 and b=700 s/mm2 groups of the right kidney with the increase of gestational weeks,the ADC values of bilateral kidneys were declining,and there was a reflection of this trend in different b values. Conclusion It is feasible for using DWI to evaluate the fetal kidney development.With a selected different b value,ADC value is a specific quantitative parameter that could help evaluating normal fetal kidney development.

Objective To investigate the therapeutic effect of aminophylline on the treatment of patients with thoracic surgery perioperative. Methods 230 cases with thoracic surgery were selected as the research objects and divided into the research group and the control group randomly, and there was 15 cases in each group. the control group were ginven closed drainage of thoracic cavity during the surgery, continued to 3 days after surgery. The control group were given intravenous drip of ciprofloxacin lactate injection at 12 h after operation, and the treatment lasted for 7 days. At this basis, the research group were given aminophylline 0.5 mg/d by intravenous injection at the beginning of anesthesia induction and continued for 3 days. The levels of lung and respiratory inflammation related factor (White blood cells, PCT, hs-CRP, TNF-α, IL-6, IL-8 and IL-10), blood gas index in the two groups pre- and post–surgery were detected, and the complications and adverse drug reactions were observed. Results 24h after surgery, TNF alpha, IL-6, IL-8 were significantly lower than those in the control group (P<0.05), and IL-10 level was significantly higher than that in the control group (P<0.05). And PaO2 in the research groupwas significantly higher than that in the control group patients (P<0.05). After treatment, arterial carbon dioxide partial pressure (PaCO2) in the two groups were significantly lower than preoperative (P<0.05). The complication rate in the research group was significantly lower than that in the control group within ten days(P<0.05). There were no adverse reactions in both groups. Conclusion During the perioperative period in thoracic surgery, aminophylline intervention can effectively improve the prognosis. .
