Periodontitis is an inflammatory disease of the periodontium. Any imbalance between the matrix metalloproteinases (MMPs) secreted by neutrophils and tissue inhibitors initiates the destruction of collagen in gum tissue, leading to chronic periodontitis. This study aimed to correlate salivary levels of MMP-8 and periodontal parameters of chronic periodontitis to establish MMP-8 as a noninvasive marker for the early diagnosis of chronic periodontitis. The study involved 40 subjects visiting the periodontic OPD of Dr. Ziauddin Ahmad Dental College and Hospital, located in Aligarh, U.P., India, from 2011 to 2012. The subjects were divided into two groups: group I consisted of 20 periodontally healthy subjects (controls) while group II consisted of 20 patients with chronic periodontitis. Chronic periodontitis was assessed on the basis of several periodontal parameters, including pocket probing depth (PPD), clinical attachment level (CAL), gingival index (GI), and plaque index (PI). Around 3 ml of unstimulated and whole expectorated saliva was collected for MMP-8 estimation by ELISA using Quantikine human total MMP-8 immunoassay kits. Data were analyzed using STATISTICA (Windows version 6) software. Salivary MMP-8 levels of groups I and II were 190.91±143.89 ng/ml and 348.26±202.1 ng/ml, respectively. The MMP-8 levels and periodontal status (PPD, CAL, GI, and PI) of groups I and II showed positive and significant correlations (for PPD, r = 0.63, P<0.001; for CAL, r = 0.54, P<0.001; for GI, r = 0.49, P<0.001; and for PI, r = 0.63, P<0.001). The results of this study demonstrate elevated concentrations of MMP-8 in individuals with chronic periodontitis.

We studied BAC biofilm during the process of initial operation and backwash. Microbial diversity decreased gradually with the increase of BAC filter depth. Proteobacteria dominated at the phylum level among the BAC biofilm samples. α-proteobacteria increased about 10% in all carbon filter depth after backwash.

运用理论分析和数值计算相结合的方法,分别从施工期和运营期角度提出了隧道抗浮稳定合理覆土厚度设定原则和理论计算方法;对于隧道施工期,考虑土体侧向摩阻力和管片环间摩阻力的影响等较为有利因素,同时考虑未凝浆液的影响等不利因素,建立了合理覆土厚度的理论计算公式;对于隧道运营期,建议只考虑隧道上覆土体自重进行抗浮,对于存在洪水冲刷的隧道设计,其上覆土体厚度还要加上设计冲刷深度;为南京某在建隧道的纵断面设计提供了一定的参考,同时也为其他过江海盾构隧道满足抗浮稳定的覆土厚度设定提供理论支持。
