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)

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

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.

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 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).

Objective To adopt a three-dimensional limited element analytic method to research into the cause and mechanism of the complications taking place after resection of head radius.Method To adopt a three-dimensional limited element analytic method to research into the stress transmission action of the head radi-us and the distribution alteration of the stress transmission after resection of head radius impacting on the stability of elbow and wrist.Result In normal cases,the stress value transmitted via head of radius takes 58% of the stress placed,36.85% via humeroulnar joint.The head of radius places a leading role in the stress transmission of the elbow joint.After rasection of the head of radius,the lateral of humeroulnar joint bears about 43% of the stress placed while the medial part bears about 21.6% of the stress.To compare with that before the resection of the head of radius the stress on the lateral is obviously increased more than the medial part.Conclusions The head of radius places a leading role in the stress transm ission of the el-bow joint.The resection of the head radius breaks the normal distribution of the stress on the elbow joint and produces great effect on the stability of the elbow joint and wrist joint.Therefore,in clinics we should pay great attention to the indication of rasection of the head of radius.
