Objective To study the relationship between vulnerable plaque and nonlacunar infarction, and analyze distribution regularity of carotid atherosclerotic plaque. Methods One hundred and four patients with ischemic stroke were divided into two groups: nonlacunar infarction group (64 cases) and lacunar infarction group (40 cases) based on imaging and clinical manifestation. Location, number, type,degree of carotid atherosclerotic plaque was recorded and compared between the two groups. Results Two hundred and ninety-seven plaques shown by the imaging were distributed in different areas:9 plaques located in the initial part of the carotid artery, 51 plaques located in the carotid artery, 148 plaques located in the bifurcation of the carotid artery, 27 plaques located in the internal carotid artery and 62 plaques located in the intracalvarium part of internal carotid artery. The percentage of severe or occlusion carotid artery stenosis in nonlacunar infarction group was 29.7% (19/64), which was higher than that in lacunar infarction group [10.0% (4/40)] (P = 0.019 ). The percentage of vulnerable plaque in nonlacunar infarction group was 62.5% (40/64), which was higher than that in lacunar infarction group [47.5%( 19/40)](P=0.004). Multivariate analysis showed that the degree of carotid artery stenosis(OR = 1.740,95% CI: 1.002 -3.021 ) and vulnerable plaque (OR = 2.865,95% CI: 1.047 - 7.813 ) was related with nonlacunar infarction.Conclusions The plaque is more frequently encountered at the bifurcation of the carotid artery. The degree of carotid artery stenosis and vulnerable plaque are the independent risk factors of the nonlacunar infarction.CT angiography can clearly display carotid artery stenosis, morphology and component of plaque, so it will be used as the preferred clinical examination.

Decellularized tissues and organs have been widely used in tissue engineering and regenerative medicine applications. The efficiency of cell removal from a tissue depends on the origin of the tissue and the methods applied. Each of these treatment affects the biochemical composition, tissue ultrastructure, and mechanical behavior of the remaining scaffold, which in turn, affect the host response to the material. Herein, we made a review about the most commonly used decellularization methods and their effects upon biologic scaffolds.

Objective: To explore the effect of immune reaction induced by alginate on parotid acinar cells in vitro. Methods: Rabbits were immunized from the conjugated alginate- BSA (1.0 mg/kg) by 40-days routine immunity method. ELJSA method was used to examine the titration (valence) of anti-alginate serum. Five groups (group A: contrast, group B: BSA, group C; alginate, group D: anti-alginate serum, group E; alginate + anti-alginate serum) were examined by MTT method at four time points( 1, 6,12 and 24 h). The growth and morphology of parotid acinar cells were observed under inverted phase contrast microscope and scanning electron microscope. Results: Antibody-serum was acquired by routine immunity method, and the titration (valence) of anti-alginate serum was 1: 400. MTT results showed that the proliferation of parotid acinar cells had been limited at 24 h( P <0.05), the other three time points showed no difference. Under inverted phase contrast microscope, a few of acinar cells whose membranes were destroyed after 12 h, some cell contents leaked out. The holes in membrane could be seen early at 6h under scanning electron microscope. Most of the acinar cells were broken at 24 h. Conclusion: The antibody-serum to alginate and immunized rabbit was acquired by routine immunity method. The immune reaction induced by alginate can destroy parotid acinar cells in vitro.
