Objective To explore the clinical value of real‐time elastography in evaluating rabbit carotid vulnerable plaque . Methods Thirty male New Zealand rabbits ( weighted from 2 .0 to 3 .0 kg) were all fed with high cholesterol diet for one week before balloon injury of their right common carotid arteries . Then they were categorized randomly into two groups which were continued fed by high cholesterol diet for 6 and 12 weeks ,respectively . Ultrasound and real‐time elastography of their right common carotid arteries were applied after their anesthesia by ear marginal vein . Strains of the carotid plaques were measured and analyzed statistically by two independent experienced sonographers . All the rabbits were sacrificed by air embolism method after all the examinations . The atherosclerotic rabbit common carotid lesions were dissected ,fixed for pathologic examination , and graded according to the standard of American Heart Association ( AHA) ,which were compared with the real‐time elastography findings . Results Real‐time elastography had well repeatability between different operators . Consistency between elastography and the AHA pathology was quite good ,with the Cohen′s kappa= 0 .803 (95% CI 0 .669 to 0 .938) . Strains of different regions in a plaque had statistically significant difference ( P <0 .000 1) . By using strain higher than 0 .37% ,the sensitivity and specificity of detecting a lipid core were 88 .0% and 81 .6% ,and area under ROC curve was 0 .902 (95% CI 0 .810 -0 .959 , P < 0 .0001) . Conclusions Real‐time elastography can display the inner elastic characteristics of the rabbit carotid plaques ,and may help evaluate the grading of a plaque . The strain value may help detect a necrotic core ,thereby help evaluate the stability of a plaque .

Objective To study the protective effects of intense pulse light (IPL) on the injury of normal human skin fibroblasts (FB) induced by ultraviolet A (UVA Ⅰ ) in vitro and to explore its possible mechanism. Methods The human skin fibroblasts were isolated and cultured, and then irradiated by UVA Ⅰ (9 J/cm2) and IPL (15 J/cm2), respectively. The proliferative ability of the cells were detected by CCK-8. Cell cycle was detected by flow cytometry, and cylin D1 and CDK2 protein expression levels were detected by Western blot. Results Different doses of UVA Ⅰ irradiation caused certain damages of cultured fibroblasts. With the increasing of of UVA Ⅰ dose, cell proliferation was decreased. Cells went to death at the exposure to 11 J/cm2 UVA Ⅰ , while the proliferative activity did not change much at 7 J/cm2 UVA Ⅰ . Cells were treated with UVA Ⅰ for other 2 days, then with IPL irradiation for other 2days, showing clear stimulating to the cell proliferation as compared with the cells that received UVA Ⅰ treatment only. Flow cytometry results showed that an increase of cell proliferating index, and cell cycle protein cyclin D1 and CDK2 expression levels were also upregulated after IPL irradiation.Conclusion UVA Ⅰ irradiation may cause cell damage as showed by cell growth index, cyclin D1 and CDK2 expression, and this injury could be protected partly by IPL treatment. The intense pulsed light may regulate the expression of cyclin proteins that may promote normal fibroblast proliferation, which could be one of the mechanisms of IPL skin rejuvenation.

Objective To investigate the anticoagulant factors that Kazakh women are prone to develop deep vein thrombosis before or after delivery.MethodsThe protein C,protein S,antithrombin Ⅲ (AT-Ⅲ) activity,activated protein C resistance ratio (APCR) of 36 Kazakh women cases and 39 Hans women cases before and after delivery were determined.ResultsThe protein S (43.13±11.36,58.05±17.10) was significant changed (P＜0.01)in Kazakh women before and after delivery.The protein C (97.34±18.37,118.02±23.46) and protein S (58.05±17.10,67.97±19.22) were statistically different between Kazakh women and Han women after delivery(P＜0.05,which protein C was P＜0.01).The anticoagulant indexes of Kazak women after delivery was still within normal range.ConclusionsNormal women have prothrombotic state before and after delivery,especially the Kazakh women.It may be an important factor of deep vein thrombosis-prone before and after delivery that protein C and protein S in Kazakh women have lower activity than that in Han women.The detection of anti-coagulation have some clinical significance on the prevention of the deep vein thrombosis in Kazakh women before and after delivery.
