Objective:To investigate the effect of PLTP gene on CSE-induced IL-8 production in human alveolar Type Ⅱcells ( Adenocarcinomic human alveolar epithelial cells , A549 ) .Methods: The different concentrations of CSE co-cultured with human alveolar epithelial cell line ( A549 ) for 24 hours.MTT assay was performed to study the effect of CSE on human alveolar epithelial cell line(A549) growth.Expression levels of PLTP mRNA and IL-8 mRNA were examined by RT-PCR,protein of PLTP were examined by Western blot ,and protein of IL-8 was examined by ELISA .Results: MTT assay showed that the proliferation of A 549 cell line were stimulated by the 0.125%CSE,while the proliferation of A549 cell tends to decrease at high concentrations of CSE (2.0% CSE and 4.0%CSE),and in this middle concentrations of CSE (0.25%CSE ,0.5%CSE and 1.0%CSE),the proliferation of A549 cell was not significantly affected .Our studys suggested that PLTP and IL-8 release were induced by CSE in a concentration-dependent and time-dependent manner ,and expression levels of IL-8 obviously increased after silence PLTP gene .Conclusion:PLTP siRNA can increased CSE-induced IL-8 production in human alveolar epithelial cells (A549).

Objective To evaluate the application of echocardiography in the diagnosis of bicuspid aortic valve and its pathophysiologic development and to demonstrate the degree of aortic valve dysfunction. Methods The echocardiographic characteristics and clinical data were analyzed retrospectively in 135 patients with bicuspid aortic valve to demonstrate the variation of aortic valve dysfunction in the progression of the course of the disease. Results Isolated aortic regurgitation was present in 68 (50%) patients, 19 (14%)patients had isolated aortic stenosis and 29 (22%)patients had combined aortic stenosis and regurgitation, 19 (14%) patients had neither stenosis nor regurgitation. Aortic regurgitation were all more commen within each age group, aortic regurgitation were also more commen within each age group in patients in their advanced course who went to surgical treatment. Conclusions Echocardiography is an effective method in the early diagnosis of aortic valve dysfunction.

OBJECTIVETo observe the effects of combination of Lumbrukinase Capsule (LC) and Probucol Tablet (PT) in treating cerebral infarction (CI) patients' unstable atheromatous plaque of the carotid artery.
METHODS150 patients were randomly assigned to the PT group and the LC group, 75 cases in each. Patients in the PT group took 0.5 g PT each time, twice daily. On the basis of PT, patients in the LC group also took 600 thousand U LC, thrice daily. The treatment course was 12 months for all. The serum levels of TC, TG, HDL-C, LDL-C, fibrinogen (FIB), and changes of the carotid atherosclerotic plaque were measured before treatment, 6 and 12 months after treatment. Meanwhile, adverse events were recorded.
RESULTSThe serum levels of TC, TG, and LDL-C were all lower 6 months after treatment than before treatment in the two groups, showing statistical significance (P < 0.05). The serum level of HDL-C was higher 6 months after treatment than before treatment in the two groups, showing no statistical significance (P > 0.05). When compared with before treatment in the same group, the serum level of FIB significantly decreased after treatment. Besides, there was statistical difference between the two groups (P < 0.05). There was no statistical difference in the serum levels of blood lipids or FIB between 12-month treatment and 6-month treatment in the same group (P > 0.05). The plaque effective rate in the LC group was superior to that of the PT group, showing statistical significance (P < 0.01). During the treatment period, the occurrence of cerebrovascular event was lower in the LC group than in the PT group (P < 0.05). Partial patients in the two groups had gastric discomfort.
CONCLUSIONSThe combination of LC and PT could prevent and treat arteriosclerosis, stabilize the plaque, effectively lower the occurrence of ischemic events. Its clinical application did not increase the risk of hemorrhage. It was safe and effective, worthy of spreading. It was necessary to further observe whether combination of LC and PT could increase side effects of the digestive tract.
