Objective To investigate relation of IL-18 and collagen fibre(CF) with plaque stability in aorta atherosclerotic lesion.Methods Morphology and content of CF in rupture of aorta atherosclerotic group(A group),non-rupture of aorta atherosclerotic group(B group) and normal aorta group(C group) were examined by Massion's staining.Expression of IL-18 by was measured immunohistochemical staining among three groups.Results Increasing and arranging turbulence of the CF was found in tunica intima,middle layer and tunica adventitia in A and B groups.Around necrosis of atheromatous plaque,CF significantly increased and arranged turbulence,but the CF decreased or disappeared in necrosis area of atheromatous plaque in A group.The CF significantly increased,arranged turbulence and extended to SMCs in necrosis of atheromatous plaque in B group.Arranging orderliness and absence of disruption of the CF was recorded in C group.Percent age of CF content was significantly different among three groups(P

Objective To discuss the characteristics of knee injury in traffic accidents so as to provide an objective basis for its forensic identification.Methods Retrospective analysis was carried out on 201 cases of knee injury in traffic accidents identified by our department from 2006 to 2009.Results According to the types of knee injury,all cases were divided into bone injury group,soft tissue injury group and bone combined soft tissue injury group.Analysis of the knee joint function in the three groups revealed that there were significant differences between bone injury or bone combined soft tissues injury groups and soft tissue injury group in weight bearing including the normal bearing rate and nonbearing rate( P < 0.05,respectively). ConclusionsIf patients' weight loading,walking functions as well as their gait conditions are introduced into the process of forensic identification for the knee injury in traffic accidents,the identification results will be more reasonable.

Objective To better understand pathological types of pediatric interstitial pneumonia and improve clinical diagnosis by analyzing the clinical records and pathological typing of interstitial pneumonia. Methods 70 cases of children diagnosed as interstitial pneumonia by autopsy were retrospectively analyzed. Results The number of males was more than that of females. There was a signiifcant predominance of infants less than 2 years. The clinical features include acute onset, rapid development, short duration and atypical clinical manifestations. Most patients had poor prognosis and curative effect with general therapies. Twelve cases had dubious etiology. Pathologic types of 58 cases with unclear etiology were diffuse alveolar damage type (DAD type, 38/58), desquamative interstitial pneumonia type (DIP type, 5/58), lymphoid interstitial pneumonia type (LIP type, 3/58), DAD type complicating DIP type (6/58), DAD type complicating LIP type (2/58), DAD type complicating respiratory bronchiolotitis-associated interstitial lung disease type (RB-ILD type, 3/58), DIP type complicating LIP type (1/58). Conclusions The conifrmed diagnosis rate was relatively low for pediatric interstitial pneumonia. Postmortem examination was helpful for diagnosis and improving clinical diagnosis and pathological typing.

Lyophylized antler powder was hydrolyzed by pepsin and trypsin separately and also simultaneously to give hydrolysates with special physical activities. Complete hydrolysis peptides with MW lower than 1 x 10(3) were collected for assay of angiotensin I-converting enzyme (ACE) inhibitory activity, antioxidant activity and proliferative activity toward UMR-106 osteoblast cells. The results of the experiments revealed that all hydrolysates exhibited potent hydroxyl radical scavenging activity with an IC50 value less than 1 mg/ml which was much lower than the value of 5.5 g x L(-1) for vitamin C. The peptic and peptic tryptic hydrolysates demonstrated strong angiotensin I-converting enzyme (ACE) inhibitory activity. The tryptic hydrolysate increased the proliferation of the UMR-106 cells by 73.43%. The results verified the traditional use of antler in bone-strengthening, anti-aging. The exploratory studies on the ACE inhibitory activity of antler hydrolysates indicated that the hydrolysates might be potentially useful in prevention and treatment of hypertension. Further purification of peptides contributing to the antioxidant activity, angiotensin I-converting enzyme-inhibitory activity and proliferative activity toward osteoblasts from antler hydrolysates is warranted.
