Objective To evaluate the efficiency of Flixotide in decreasing the incidence of asthma following bronchiolitis.Methods 23 children with brochiolitis received Flixotide daily while other 29 subjects not intervented as control.The intervention duration was 60 days,then followed up for more then 1 year.Results After following up over 1 year,only 3 cases in 29 patients with brochiolitis receiving Flixotide developed into asthma.However,24 cases in control group developed into asthma.The incidence of asthma was 13.04% and 82.76% in two group,respectively.Conclusion Flixotide may be an effective intervention to prevent the development of asthma after bronchiolitis.

Objective To reconstruct the three-dimensional(3D) image and to study on the virtual anatomy of the thigh part based on computed tomography(CT) data source. Methods Ten patients' contrast-enhanced light-speed CT images of the thigh part were chosen, “3D medical studio” was applied to read CT data, then to reconstruct and anatomize the thigh part. Results The reconstructed 3D images of the thigh part were realistically pseudocolored displayed, it was composed of four kinds of tissues(skin, muscle, skeleton and artery) and could be freely rotated and incised and restored for many times at any shape and depth on real time. Its' layers were distinct among tissues. Conclusion This research realizd partial function of virtual anatomy, it may play a definite role on regional anatomy and sectional image anatomy teaching and clinical radiology diagnosis.

BACKGROUND: Polyblends composed of thermoplastic polyurethane elastomer (TPU) and bisphenol A type of polysulfone (PSF) or polymethyl methacrylate (PMMA) can improve the properties of TPU, bisphenol A type of polysulfone or PMMA and can widen the scope of application. The property of polyblends bad or good depends on the miscibility of polyblends. The dilute-solution viscometry (DSV) is a simple and rapid way for determining the miscibility for polyblends. The study on the determination of miscibility for TPU/PSF and TPU/PMMA polyblends by the DSV has not been reported up to now. OBJECTIVE: To differentiate the miscibility of TPU/PSF polyblend and that of TPU/PMMA polyblend, and at the same time to verify the consistency of μ and α criteria in the determination of polyblend miscibility by DSV.DESIGN: Observation and contrast analysis based on the two polyblend systems.SETTING: Chemical Engineering and Pharmaceutics College, Henan University of Science and Technology.MATERIALS: TPU sample was purchased from Luoyang Jiming Chemical Industry Limited Company, China. PSF sample was purchased from the First Plastic Factory of Dalian, China. PMMA sample was synthesized by our laboratory. N, N-dimethylformamide was provided by Beijing Chemical Plant.METHODS:This study was performed at the Key Laboratory of Polymer Science and Nano-technology, Henan University of Science and Technology in May 2006. The different molar ratio of TPU / PSF and TPU / PMMA polyblends were prepared in N, N-dimethylformamide. An ubbelohde dilution viscometer (whose inner diameter was between 0.5 mm and 0.6 mm) was employed for measuring the relative viscosities of the polymer solutions in DMF at (25±0.01) ℃. The second stop-clock was used to record efflux time. From the efflux time, the relative viscosities could be obtained. Then the specific viscosities could be given by the relative viscosities value. From a series of relative viscosities, the specific viscosities and other data of two polyblends, μ values and α values of two polyblends were obtained.MAIN OUTCOME MEASURES: The efflux time of two polyblend solutions in an ubbelohde viscometer.RESULTS: The μ and α values of TPU/PSF polyblend were all above zero, which showed that TPU/PSF polyblend was miscible. But the μ and α values of TPU/PMMA polyblend were all below zero, which showed that TPU/PMMA polyblend was immiscible. CONCLUSION:The μ criterion is consistent with the α criterion in judging for polyblend miscibility. DSV method is simple, and it can be used in the determination of polyblend miscibility.

0.05). The mainly side-effects were myelosuppression, nausea, and vomiting. Conclusions:Docetaxel/cisplatin and gemcitabine/cisplatin regimens were well toleranced in advanced NSCLC patients with long term survival.

Objective To reconstruct three-dimensional (3D) image of heart and coronary artery on internet and explore the reliability. Methods After the contrast medium was injected into coronary artery of 2 heart specimens, hearts were scanned by UFCT with enhancement volume. One patient's UFCT images of coronary artery angiography were also chosen.Then the primitive images were transposed format, removed noise, specified interesting areas. 3D software on server was applied to reconstruct heart and coronary artery. Results The reconstructed 3D images of the heart and coronary artery were realistically displayed, freely rotated and transected.Main parts and branches of coronary artery were similar to those in the images of the UFCT. Conclusion Heart and coronary artery can be reconstructed on internet,which offers a new approach for reconstructing organs and tissues of human being.;

AIM: To evaluate the relationship between coexpression of EGFR and ERK2 on the level of protein and mRNA and activation of ERK2 in lung squamous cell carcinomas (SCC). METHODS: Twenty cases of lung squamous cell carcinomas and their paired normal lung tissues were studied. The expression of mRNA and protein of EGFR and ERK2 was measured by reverse transcription PCR (RT-PCR) and Western blotting, respectively. The activity of ERK2 was detected by immunoprecipitation and kinase reaction. RESULTS: The results showed that the expression of EGFR mRNA and protein in paired normal lung tissues was hardly detected by RT-PCR and Western blotting, respectively, but in 20 cases of lung SCCs their expression was upregulated significantly. Compared with normal lung tissues, the expression of ERK2 mRNA and protein in lung cancer tissues was also upregulated significantly, the latter increased about 3-5-fold, and the activity of ERK2 in lung SCCs was also markedly activated. CONCLUSIONS: These data highlight that the overexpression of ERK2 and EGFR protein occurs simultaneously in lung SCCs, which mainly results from the increasing level of gene transcription, the increased activity of ERK2 in lung cancer tissues perhaps attributes to the upregulation of coexpression of EGFR and ERK2.

Normal function of growth hormone-insulin-like growth factor Ⅰaxis is essential for linear growth after birth. A case of continuous growth with undetectable growth hormone level even under insulinhypoglycemia stimulation was reported. The growth hormone deficiency was due to pituitary stalk interruption combined with deficiency of multiple pituitary hormones. Taken together with reviewed literature, this so-called nongrowth hormone-dependent linear growth was preconditioned by other hormones, especially gonadotropin deficiency,and the unclosed epiphysis.

UNLABELLEDThis study was conducted to reconstruct three-dimensional medical images based on web and to achieve highly realistic display. Using the volume rendering techniques to reconstruct and display three-dimensional images in Java Applet program and utilizing signed Applets for solving security problem, We got two-dimensional images of human organs from ultrafast CT as sources and reconstructed the organs configuration of heart, coronary artery, head, cervical vertebrae, and pelvis. This reconstruction can be run in Web browser on different kinds of computers and for virtual surgical planning.

CONCLUSIONS1. Three-dimensional medical image reconstruction in Web browser implemented by Java Applet is feasible, which will prompt clinical use of three-dimensional images. 2. The solid conformation of human organs, especially the anatomic structure of the coronary artery, can be displayed by using three-dimensional reconstruction techniques, which may offer more information to clinics.
