ObjectiveTo determine the possibility of r eal-time perfusion imaging in the quantitative evaluation of myocardial perfusion in various segments of left ventricle. MethodsImages of ten anesthetized dogs were obtained at the mid-papillary muscle short-axis view with a real-time imaging system. Mechanical index (MI) was adjusted to 0.1 , 0.2 and 0.4 respectively, and frame rate was set at 20 Hz. Optison was infused intravenously at a rate of 0.1 , 0.2 and 0.5 ml/min, respectively. Images were recorded for 150 real-time frames commencing immediately after a couple of Doppler bursts. Myocardial opacification was assessed both visually and quantitatively for six segments of left ventricle (antero- and infero-septum, inferior, posterior, lateral and anterior wall). Myocardial signal intensity versus real-time frame curves were made and fitted to an exponential function: Y=A(1-e -?t ). ResultsUsing low MI (MI= 0.1 or 0.2 ) and with continuously infusion of Optison at a rate of 0.2 or 0.5 ml/min, real-time imaging resulted in sufficient myocardial opacification and left ventricular endocardial border definition, and displayed myocardial thickening and wall motion simultaneously. ConclusionsReal-time imaging has a potential in the quantitative assessment of myocardial perfusion, and allows simultaneous assessment of perfusion and myocardial function.

Objective To analysis the progress in prevention and control of iodine deficiency disorders (IDD) in Dalian and to provide a scientific basis for further prevention and control of the disease.Methods From 2006 to 2010,5 or 9 townships were randomly sampled from each county in Dalian,4 villages were sampled from each selected townships and 15 or 8 households were sampled from each selected villages for collecting salt samples and salt iodine level was determined by direct titration method.Sixty daytime urine samples from pregnant women,breast feeding women,infants and young children were collected,respectively,every year to detect urinary iodine level.From 2007 to 2009,2 to 11 counties were sampled and from each selected county one school was sampled to collect 100 daytime urine samples of children aged 8-10 and iodine content was determined.From 2006 to 2009,2 to 5 counties were sampled,from each selected county 2 to 5 schools were sampled and 100 children aged 8 to 10 in each selected school were sampled to detect intelligence quotient level and the thyroid volume.Results From 2006 to 2010,16 012 copies of households' edible salt samples were monitored; the average iodine content was ranged 29.68-31.51 mg/kg,the rate of qualified iodized salt in household ranged from 97.24％ to 98.42％.A total of 1398 copies of urine samples of pregnant women,486 breast feeding women,473 infants and 502 young children were monitored,and the median value of urinary iodine was 129.3-189.6,114.6-190.6,148.5-298.5 and 144.4-187.3 μg/L,respectively.A total of 1657 urine samples were monitored,1264 intelligence quotient level and 1197 thyroid volume of school-age children were determined,the median urinary iodine,thyroid goiter rate and intelligence quotient level was 217.9-266.7 μg/L,0-3.29％ and 110.4-117.2 μg/L,respectively.Conclusions From 2006 to 2010,the city's households qualified iodized salt coverage rate has reached the national standard for elimination of iodine deficiency disorders.The iodine nutrition of key population and school-age children has reached adequate level,the thyroid goiter rate is less than 5％,and the level of intelligence quotient has increased every year.But the iodine nutrition of breast feeding women in 2009 and 2010,pregnant women in 2010 is inadequate,so iodine nutrition surveillance and health education in pregnant and breast feeding women need to be strengthened in the future.

Objective:To determine the basic characteristics and clinical manifestations of hospitalized patients with psoriasis in Hunan, and to provide reasonable reference for the etiology and treatment of psoriasis.
Methods:Totally 190 patients with psoriasis from January 1, 2012 to December 31, 2012 treated in the Department of Dermatology, the Second Affiliated Hospital of Central South University were retrospectively analyzed. The data were analyzed by SPSS17.0.
Results:The ratio of male to female inpatient numbers was 3.13:1, aged was between 40 and 70 years. The most common subtype of psoriasis was psoriasis vulgaris (64.73%), followed by psoriatic erythroderma (18.42%). The distribution of the subtype of psoriasis did not differ by gender. Nineteen patients recalled clearly the cause of proriasis, 5 of which were caused by medicine, and 4 by drinking. Totally 96 cases accompanied with other diseases, 24.21%of which accompanied with cardiovascular system disease.
Conclusion:There is no season difference in the hospitalization of patients with psoriasis. there are more male than female inpatients. Treatment of psoriasis should consider clinical classification, drug adverse reactions, and individual factors for individual treatment.

BACKGROUND:5-Fluorouracil occupies an important position in the treatment of gastric cancer, but its long-term use can easily induce adverse reactions such as myelosuppression and leukopenia. Polylactic acid and its copolymers have a higher biocompatibility, and their decomposer cannot gather in the body.
OBJECTIVE:To investigate the in vitro cytotoxicity mechanism of 5-fluorouracil-loaded polylactic acid nanoparticles on gastric cancer cel lines.
METHODS:Ten mice were selected in this study. 5-fluorouracil-loaded polylactic acid nanoparticles (1×10-7, 1×10-6, 1×10-5, 1×10-4 mol/L) were prepared using ultrasonic emulsification method. Kiling effect of polylactic acid nanoparticles on gastric cancer cel lines in vitrowere detected. Then, the inhibition rate was calculated at different concentrations.
RESULTS AND CONCLUSIONS: Under the transmission electron microscope, 5-fluorouracil-loaded polylactic acid nanoparticles had good shape and relatively evenly distributed with no adhesions. After drug administration, the drug concentration was 50% at 24 hours and 62.9% at 72 hours. After 48 hours co-culture with single 5-fluorouracil or 5-fluorouracil-loaded polylactic acid nanoparticles, the viability of gastric cancer cels showed a decrease trend with the increase of drug concentrations, and moreover, 5-fluorouracil-loaded polylactic acid nanoparticles had a better cel inhibition ability than the single 5-fluorouracil (P < 0.05). The IC50value of 5-fluorouracil-loaded polylactic acid nanoparticles was significantly lower than that of 5-fluorouracil (P < 0.05). These findings indicate that polylactic acid nanoparticles as good drug carriers have a strong drug loading capacity and increase drug concentration in the body, but cannot reduce the biological activity of 5-fluorouracil, which provide new ideas for the treatment of gastric cancer.

Interleukin 24 ( IL-24) has a good prospect in tumor therapy because it can specifically inhibit proliferation in a variety of tumor cells in vitro and in vivo and induce apoptosis of tumor cells without affecting normal cells .Gene therapies which use recombinant adenovirus as a vector have some limitations that restrict the clinical application of IL-24. In comparison, protein drugs have tremendous advantages .In this paper, the progress in research on IL-24 gene engineering protein is elaborated .

Objective To observe the clinical effect of moxibustion on body sub-health fatigue state.Methods 120 cases of body sub-health patients were randomly divided into A,B,C three groups,with 40 cases in each group.Group A was treated with moxibustion,group B was treated with acupuncture therapy,and group C (control group) did not receive any measure of treatments.Fatigue scale (FS) was adopted to the three groups respectively for measuring physical fatigue score,mental fatigue score and total fatigue score before and after the treatment.Treatment efficacy was evaluated and analyzed after three weeks of continuous treatment.Results The total score of fatigue scale was 6.10 ± 2.47、6.82± 2.36、and 10.10±2.66 respectively in group A,group B and group C.Compared with group C,the difference in group A and group B was statistically significant (P＜0.01).Compared with group B,the difference in group A was not statistically significant (P＞0.05) ; The Physical fatigue points of group A,B,C was 2.46± 2.06、3.60 ± 2.24 and 5.03 ± 2.66 respectively.Compared with C group,the difference in group A and group B was statistically significant (P＜0.01).Compared with group B,the difference in group A was statistically significant (P＜0.05).Conclusions Moxibustion and acupuncture can effectively improve patients total body sub-health state of fatigue.Moxibustion treatment showed better effects in alleviating physical fatigue,

Objective To explore the significance of language proficiency in bilingual perception in Chinese-English late bilingual subjects with block-design functional magnetic resonance imaging (bfMRI).Methods Thirteen right-handed Chinese Han healthy male late bilinguists who had limited English proficiency were scanned while listening to short sentences in Chinese and English.Based on blood oxygenation level-dependent (BOLD) signal efficacy,functional images were collected using a 1.5-T MRI.Statistical parametric mapping 2 (SPM2) was used to analyze the data of functional images (P＜0.001,KE＞ 100).Results For Chinese familiar voices,more significant activation was observed in the right superior temporal gyrus than that for English familiar voices.On the contrary,more significant activations for English familiar voices were observed in the left precuneus,middle frontal gyrus and left posterior cingulate cortex compared with that for Chinese familiar voices.For Chinese unfamiliar voices,more significant activations were observed in the right middle temporal gyrus and right medial frontal gyrus than that for English unfamiliar voices.In contrast,more significant activations by English unfamiliar voices were observed in the right inferior frontal gyrus,middle frontal gyrus and left middle temporal gyrus compared with that for Chinese unfamiliar voices.Conclusion Language proficiency may play an important role in different language perception from auditory level.

In order to obtain nucleotides aptamers bind to IgE, 80 bp nucleotides single-stranded DNA library containing 40 random nucleotides was designed and synthesized. Oligonucleotides that bind to human Cepsilon3-Cepsilon4 protein were isolated from ssDNA pools by the systematic evolution of ligands by exponential enrichment (SELEX) method using nitrocellulose filters as screening medium. Through the optimization of critical PCR and asymmetric PCR parameters including annealing temperature, cycles, and molar ratios of target protein and ssDNA etc, a suitable screening system was established. The aptamers of Cepsilon3-Cepsilon4 protein with high affinity and high specificity were identified by ELISA with biotin-streptavidin-horseradish peroxidase system, and its primary sequence and second structure were analyzed by DNAMAN package and DNA folding sever after being cloned and sequenced. Moreover, target protein was bound to one aptamer and another aptamer modified with biotion together forming a sandwich-like complex, which was captured in microwell to detect IgE concentration using the optimal combination in the sandwich method named enzyme-linked aptamers sorption assay (ELASA). The method could be used for the quantitative detection of human IgE, and whose sensitivity reached to 120 ng x mL(-1).
