0.05].After 12 week treatment,the YGTSS total score in study group was significantly lower [(27.88?14.24) vs(36.53?17.45) scores] and the reduction rate of YGTSS score was significantly higher [(43.12?18.42)% vs(33.49?14.38)%] compared with those in control group(Pa

Perforator stroke(PS)is one of peri-procedural complications associated with stenting of intracranial arterial stenosis.A lot of perforator arteries are derived from intracranial arteries with difference from coronary arteries,because once the intracranial perforator arteries of crucial regions are occluded,may lead to fatal prognosis.Three hypothesis have been used to explain PS including snow-plowing,stent jailing effect and in-stent neointimal growth.In vivo models,investigators have already found these phenomenas.After much attention been paid on PS,authors have published a report covered with a large amount of cases in 2006. The author figured out that patients with perforator infarct adjacent to the stenotie segment(PIAS)under MRI beforehand would have higher chance occurring PS after stenting of intracranial stenosis.The patients with priority of PS easily are affected by the morphology,location,etiology,sites,the type and equipments.Many yet unsolved problems including the prevention would arouse us to go deeper into for the exploration of the mechanism.(J Intervent Radiol,2007,16:858-862)

Universities are cradles of leadership and full-developed specific professional.Besides specific courses,reasonable sexual health education should be set up to make the students succeed when they grow up.

Objective To discuss the application of prospective risk nursing measures in reducing the occurrence of postoperative local hematoma at femoral artery puncture site. Methods A total of 605 patients receiving femoral artery puncture for interventional management were collected as the control group , and 322 patients were used as the intervention group. The risk factors causing postoperative local hematoma at femoral artery puncture site in the control group were recorded, and based on which risk estimation survey table was designed. According to risk estimation survey, the prospective intervention measures, including risk assessment, standardization of professional training, individual health education, the improvement of care appliance, etc. were carried out for the patients of the intervention group. The occurrences of postoperative local hematoma at femoral artery puncture site were recorded and the results were compared between the two groups. Results No statistically significant differences in demographic and clinical data existed between the two groups. However, the incidence of hematoma in the intervention group was significantly lower than that in the control group (χ2 = 4.652, P < 0.05), although the difference in the severity of hematoma was not significant between the two groups. Conclusion The use of prospective risk nursing measures can effectively reduce the incidence of postoperative hematoma at femoral artery puncture site.

Objective Adsorption effect of dietary fibers from seaweeds on extrinsic estrogens was studied.Methods The methods included the tests in vivo and in vitro which simulated environments of stomach and small intestine of rat. Results The adsorption effect of four kinds of dietary fibers on estradiol in simulated environments of small intestine was better than that in simulated environments of stomach. The effect of Laminaria japonica was the best. And the rate of adsorption on estradiol was 108 g?g~ -1.It is 1.5,1.8, 3.1, and 3.0 times that of Sargassum,wheat blan,Gracilaria and Eucheuma,respectively. The rates of adsorption on estradiol of four kinds of dietary fibers from Gracilaria, Eucheuma, Sargassum and laminaria japonica was 11.1%,13.6%,27.5% and 38.7%, respectively. Adsorption rate of Sargassum and laminaria japonica was 1.9 and 1.3 times than that of wheat bran, respectiveiy which was 20.4%. While for Gracilaria and Eucheuma, adsorption rate was lower than that of wheat bran. Conclusion The dietary fibers from four seaweeds showed adsorption effect on extrinsic estrogens. The dietary fibers from brown seaweeds (Sargassum and laminaria japonica) had more adsorption effect than that of red seaweeds (Gracilaria and Eucheuma).

Hyperlipidemia is a major factor causing coronary heart disease and atherosclerosis. The high-density lipoprotein cholesterol (HDL-C) is a major indicator for measuring lipid levels. However, there is no an effective medicine that can obviously increase HDL-C at present. According to previous laboratory studies, atractylodes macrocephalae extracts could significantly increase HDL-C level. In this study, the metabolic hyperlipidemia rat model was established by feeding high-sugar and fat diets and alcohol-drinking to explore the effect and mechanism of atractylodes macrocephalae extracts on hyperlipidemia rats. According to the findingins, different doses of atractylodes macrocephalae extracts could reduce the levels of TC, TG, LDL-C, ACAT and increase the contents of LCAT, HDL-C. Particularly, the atractylodes macrocephalae extracts (100 mg · kg(-1) group showed increase in HDL-C by about 50% and significant declines in HMG-CoA reductase, TC, TG. In conclusion, Atractylodes Macrocephelae Rhizoma extracts could effectively regulate the dyslipidemia of hyperlipidemia rats, especially on HDL-C. Its mechanism may be related to reduction in cholesterol synthesis by inhibiting HMG-CoA reductase in livers and increase in lipid metabolism and transport by regulating LCAT and ACAT levels.

Objective:To investigate the relationship between ciaH, eno, pykF genes and fluoride resistance through determining the differential expressions of ciaH, eno and pykF genes of fluoride-resistant Streptococcus mutans cultivated in fluoride environment. Methods:The cultured Streptococcus mutans and their fluoride-resistant strains were divided into UA (Streptococcus mutans subcultured in BHI without NaF), FR (fluoride-resistant Streptococcus mutans subcultured in BHI without NaF) and FFR (fluoride-resistant Streptococcus mutans subcultured in BHI containing 1 g·L-1 NaF) groups.After 11 h (logarithmic phase) and 20 h (platform stage) cultivation, the expression levels of ciaH, eno and pykF mRNA were detected by RT-PCR method.Results:Compared with FR group, the expression levels of ciaH, eno and pykF mRNA in FFR group were increased both in the logarithmic phase and the platform stage(P<0.05 or P<0.01).Compared with UA group, the expression levels of eno and pykF mRNA in FR group were decreased both in the logarithmic phase and the platform stage(P<0.01), whereas the expression level of ciaH mRNA had no significant difference in the logarithmic phase (P>0.05), but it was increased in the platform stage (P<0.01).Conclusion:Fluoride can increase the expression levels of ciaH, eno and pykF genes in fluoride-resistant Streptococcus mutans, indicating that these genes are related to the production of fluoride resistance.

The potential of Rhizobium sp. N613 to produce the exopolysaccharide (REPS) was studied in this paper. Using an orthogonal design in a flask-shaker culture system, the fermentation medium and conditions of synthesizing REPS were optimized. Based on these results, the fermentation kinetic parameters were obtained in the batch fermentation with a 10L fermentor. The REPS yield of 11.31g/L was achieved by metabolic regulation during 40 h fed-batch fermentation. Transplanted tumor models of sarcoma 180 in mice were used to evaluate the anti-tumor effect. The result of anti-tumor activities showed that inhibition rate was 53.40%, when dose of REPS was 5mg/kg. These results indicate that REPS has the following properties: the short duration of fermentation, the high yield, the low cost, the effective immunocompetence and thickening. Thus, REPS has the value of development and application.
